PCT / EP2015 / 073478 surface cleaning machines are known. From the non-prepublished PCT / EP2015 / 073315 a surface cleaning machine is also known. The object of the invention is to provide a surface cleaning machine of the type mentioned at the outset, which provides optimized cleaning results with ease of operation. This object is achieved according to the invention in the surface cleaning machine mentioned above, that in a cleaning operation

Surface cleaning machine is supported only on the cleaning roller unit with the rotation axis on a surface to be cleaned, a drive motor for the cleaning roller unit is provided, and a dirt fluid tank means is provided, which is removably mounted on the cleaning head.

The fact that the surface cleaning machine is supported only on the cleaning roller unit on a surface to be cleaned, there is a relatively simple construction of the surface cleaning machine, which can be realized with low weight.

The cleaning roller unit is a one-piece or multi-part cleaning roller with a single axis of rotation. In a multi-part cleaning roller unit all subunits have the same coaxial rotation axis and in the cleaning operation, all subunits are rotated about the same axis of rotation in the same direction of rotation at the same rotational speed and the drive motor drives all subunits. Furthermore, then a cleaning can also be done in hard to reach areas, since the space required for the cleaning head can be kept low. The driven cleaning roller unit also acts as a support device; As a result, no further driving elements such as wheels or the like must be provided.

By a removable Schmutzfluidtankeinrichtung on the cleaning head can be the way for dirt fluid from the cleaning roller unit to the Keep the dirt fluid tank device small so that simple coupling is possible.

Due to the removability of Schmutzfiuidtankeinrichtung of the

The cleaning head can be easily emptied and cleaned. It can absorb a large amount of dirt fluid including a liquid. In particular, the Schmutzfiuidtankeinrichtung can be removed as a whole from the cleaning head or use as a whole in this, so that a high degree of filling for the

Schmutzfiuidtankeinrichtung can also be achieved with liquid.

It is thereby even possible to realize a coupling of dirt fluid from the cleaning roller unit to the Schmutzfiuidtankeinrichtung suction fan free or it can be provided to support a suction fan, which has a relatively low power consumption and thus a relatively low energy consumption.

As a result, it is possible to supply the surface cleaning machine and in particular the drive motor with a preferably rechargeable battery device with electric current. The surface cleaning machine can thus be operated independently of the mains.

It is advantageous if a longitudinal axis of the Schmutzfluidtankein- direction parallel to the (in particular single) axis of rotation of

Cleaning roller unit is oriented. The longitudinal axis of the

Schmutzfiuidtankeinrichtung extends between a first end face and a second opposite end face of the Schmutzfiuidtankeinrichtung. It specifies the longest extension of the dirt refueling device. This results in a space-saving arrangement of Schmutzfiuidtankeinrichtung on the cleaning head. It is also advantageous if a motor axis of the drive motor is oriented transversely and in particular perpendicular to a longitudinal extension axis of the dirty fluid tank device. The motor axis of the drive motor corresponds to a rotor axis of the drive motor. The transverse orientation to the longitudinal extension axis of the dirty fluid tank device results in a space-saving construction.

It is particularly advantageous if the dirty fluid tank device is arranged between the cleaning roller unit and the drive motor. This results in a short Einkopplungsweg for coupling of

Dirt fluid from the cleaning roller unit in the Schmutzfluidtankeinrichtung. In turn, it is sufficient to use a suction fan with a relatively low power for the suction of dirt fluid or it is a suction fan-free training possible.

In one embodiment, a torque transmitting transmission device is provided, which is disposed between the drive motor and the cleaning roller unit, wherein the dirty fluid tank means having an upper side and a lower side, wherein the underside faces a cleaning roller holder of the cleaning roller unit and faces away from the upper side of the underside, and wherein the Transmission device is guided past the bottom or at the top of the dirty fluid tank device. The transmission device provides the torque transmission from the drive motor to the cleaning roller unit. The

Cleaning roller unit is positioned spaced from the drive motor. The transmission device provides in particular for a speed reduction, torque reversal and possibly for a bridging of

Intervals. By passing the transmission device on the underside or top side of the dirty fluid tank device results in a simple compact design. In principle, it is also possible that the transmission device is performed by a through opening in the Schmutzfluidtankeinrichtung. When passing the transmission device on the underside or top side results in comparison in addition a simplified removability of the Schmutzfluidtankeinrichtung of the cleaning head and a simplified design of the Schmutzfluidtankeinrichtung. In one embodiment, the dirty fluid tank device has a recess in which at least one partial region of the transmission device is positioned when the dirty fluid tank device is fixed to the cleaning head. Through the corresponding free space of the recess, a space is provided in which the transmission device can be positioned.

This results in an optimized adaptation of the geometric shape of the dirty fluid tank device to the cleaning head.

In one embodiment, a device body is provided, on which the cleaning head is arranged, wherein at least one of the following devices is positioned on the device body: a tank device for cleaning fluid; a valve device for the supply of

Cleaning fluid to the cleaning head; a battery device for the drive motor; a holding rod device for holding and / or guiding the surface cleaning machine; a filter device for cleaning fluid; at least partially the drive motor. This results in a compact structure. In particular, elements of the surface cleaning machine which have a relatively high weight, such as the drive motor, can be positioned far down in the vicinity of the cleaning head. Furthermore, a removable tank device for cleaning fluid can be positioned on the device body, for example. Protected in the housing, a valve device for the supply of cleaning fluid to the cleaning head and also a filter device for the cleaning fluid can be positioned on the device body. Furthermore, the battery device can be optimally positioned, in particular if the

Drive motor itself is arranged on the device body. It can also be provided that at least partially the drive motor is positioned in the device body. For example, the device body is used to "anchor" the drive motor to the surface cleaning machine. It is advantageous if the drive motor is arranged at least partially between the device body and the cleaning head, wherein it is in particular at least partially disposed in the device body. As a result, for example, a battery device can be arranged in an optimized manner on the device body. Furthermore, torque transmission from the drive motor to the cleaning roller unit on the cleaning head can be realized in a simple manner. In this case, the drive motor can be arranged relatively far down (relative to a proper operation with cleaning roller unit supported on the surface to be cleaned), so that a simple operability results. It can be realized with such an arrangement in a simple way a pivoting between the cleaning head and the device body. It is advantageous if the cleaning head is pivotable about a pivot axis relative to the drive motor and / or the device body, wherein the pivot axis is oriented in particular parallel or coaxial with a motor axis of the drive motor. This results in extended operating options; it improves access to confined spaces of the area to be cleaned, as the device body adapted to the

Cleaning head can be repositioned. A corresponding pivot bearing can be formed in a simple manner, for example by encapsulating the drive motor as an inner sleeve and an outer sleeve arranged on the device body are designed so that a pivot bearing is realized.

In one embodiment, a cleaning roller holder, on which the cleaning roller unit is positioned, has a receiving chamber with a receiving space for the dirty fluid tank device. The receiving chamber may be multi-chambered and the receiving space may include a plurality of subspaces. In principle, subspaces can be connected to one another in a fluid-effective manner or can be separated from each other in a fluid-efficient manner. In particular, the receiving chamber is associated with a fixing device by which the Schmutzfluidtankeinrichtung is fixed to the receiving chamber, wherein the fixing device for the removability of the dirty fluid tank means of the cleaning head is detachably formed and in particular the fixing device is formed so that the Schmutzfluidtankeinrichtung to the receiving chamber by positive locking is held in a holding position. This makes it possible in a simple manner to achieve a fixation of the dirty fluid tank device on the receiving chamber. Furthermore, the Schmutzfluidtankeinrichtung can be easily removed to empty them and optionally clean. Furthermore, the

Fixing device may be formed so that the Schmutzfluidtankeinrichtung is positioned with an inlet opening defined to the cleaning roller unit. Thereby, in particular, a wiping guide can be positioned defined to the cleaning roller unit.

In a structurally simple embodiment, the fixing device comprises at least one pivotable flap or is such. Due to the pivotable flap, the receiving chamber can be released in a simple manner such that the dirty fluid tank device can be inserted or removed. By the flap, when acting on the dirty fluid tank means, further, a holding position of the dirty fluid tank means can be secured. Furthermore, the flap may be formed to exert a certain bias to position the dirty fluid tank means defined on the receiving chamber, in particular to position an inlet mouth of the dirty fluid tank means and / or optionally a scraper deflector defined relative to the cleaning roll unit. Conveniently, a pivot axis of the at least one flap is aligned at least approximately parallel to a rotational axis of the cleaning roller unit. This results in a simpler constructive Construction. The Schmutzfluidtankeinrichtung can be easily removed and replaced.

It is favorable if the at least one flap acts on an upper side of the dirty fluid tank device, which faces away from a lower side, wherein the underside of the dirty fluid tank device faces a bottom of the receiving chamber when the dirty fluid tank device is fixed to the cleaning head. As a result, a holding position of the dirty fluid tank device on the receiving chamber can be secured in a simple manner. Furthermore, a defined positioning can be achieved.

It is advantageous if the at least one flap is designed as a hold-down, which the Schmutzfluidtankeinrichtung in relation to the

Cleaning roller unit defines positioned and / or positioned in the receiving space and in particular the dirt fluid tank means in a holding position against a bottom of the receiving chamber suppressed. As a result, the dirty fluid tank device can be easily removed or replaced by an operator and, to a certain extent, an automatic positioning can be achieved; the operator does not have to worry about the exact positioning.

For example, the at least one flap is spring-loaded and / or designed to be elastic such that the dirty fluid tank device is held in the receiving space with a bias. This bias ensures that the inlet mouth of the dirty fluid tank means is in a defined position relative to the cleaning roller unit.

In a structurally simple embodiment, at least one recess is arranged on the upper side of the dirty fluid tank device and the at least one flap has at least one counter element for immersion in the at least one recess. This makes it possible in particular to easily block the mobility of the Dirtfluidtankeinrichtung reach the receiving chamber in a take-out direction.

It is furthermore advantageous if the at least one recess has at least one undercut and the at least one counter element has a blocking element adapted to the at least one undercut which, when the at least one flap is closed, blocks mobility of the dirty fluid tank device in one direction away from a bottom of the receiving chamber , It can thereby achieve a positive connection, which ensures falling out in the holding position of the dirty fluid tank means. Furthermore, this makes it possible in a simple manner to achieve a positioning of the dirty fluid tank device relative to the cleaning roller unit.

In particular, the receiving chamber and the Schmutzfluidtankeinrichtung are adapted to be adapted to each other, that in a holding position of the Schmutzfluidtankeinrichtung on the receiving chamber a mobility of the

Schmutzfluidtankeinrichtung is transversely locked to a vertical of a bottom of the receiving chamber. This results in a simple way a fixation. The floor then provides a blockage of mobility parallel to the vertical of the floor and the flap provides for blocking the mobility in the opposite direction thereto.

In one embodiment, the dirty fluid tank means comprises one or more hinged lids. By opening the hinged lid, the Schmutzfluidtankeinrichtung can be emptied and, if necessary, this can be cleaned easily. The hinged lid forms, in particular, an upper side of the dirty fluid tank device, onto which the at least one flap of the fixing device can act. In one embodiment, the dirty fluid tank means is formed as a unit. This can include one or more chambers. It is as a whole of the cleaning head removable or usable in this. It is also possible in principle the Schmutzfluidtankeinrichtung has separate subunits, which are individually removed from the cleaning head

or can be used on this. In one embodiment, the cleaning roller unit is formed in two parts (is a two-part cleaning roller) with a first part and a second part, wherein the first part of the cleaning roller unit, a first chamber of the dirty fluid tank means and the second part of the cleaning roller unit, a second chamber of Schmutzfluidtankeinrichtung is assigned and in particular, the drive motor acts on a central region which lies between the first part and the second part. The central area is, for example, the middle area of a wave. This results in a space-saving and structurally simple design for the transmission of torque from the drive motor to the cleaning roller unit with the (exactly one) rotation axis. In particular, this allows the drive motor to be positioned so that its motor axis is transverse to the axis of rotation of the cleaning roller unit.

It is advantageous if a stripping guide device for dirty fluid is provided, which acts on the cleaning roller unit and which is arranged on an inlet opening of the dirty fluid tank device. The wiping guide device makes it possible to detach dirt from the cleaning roller unit, and the detached dirt can be coupled in in particular into the dirty fluid tank device via the inlet mouth.

In particular, the scraper-guide is arranged and configured such that dirt fluid, which is entrained by the cleaning roller unit, which is removed by stripping the cleaning roller unit and is directed to the input mouth of the dirty fluid tank means. The coupling of dirt fluid at the inlet mouth into the dirty fluid tank device can at least partially take place via a baffle effect also by the action of the centrifugal force. It can be at least partially Dirt fluid are thrown over the wiper guide at the inlet mouth in the Schmutzfluidtankeinrichtung.

It is particularly advantageous if the wiping guide device is embodied so that dirt fluid is guided through the wiping guide at the inlet mouth of the dirty fluid tank device into the dirty fluid tank device without any fan of suction. The wiping guide is then arranged in particular directly at the inlet mouth of the dirty fluid tank device. In particular, the stripping guide itself forms a wall of the inlet mouth. This results in a total of a structurally simple construction of the surface cleaning machine, since no suction fan with fan motor, vacuum lines and the like must be provided. Furthermore, no separator must be provided. It is also advantageous if, based on a direction of rotation of the cleaning roller unit, the stripping guide is arranged downstream of the inlet mouth. As a result, dirt fluid can be detached from the cleaning roller unit via a stripping effect and directed into the dirty fluid tank device. It is particularly advantageous if the wiping guide protrudes into a trimming of the cleaning roller unit. As a result, dirt fluid can be released from the cleaning roller unit via a wiping effect.

It is advantageous if the wiping guide is rounded or chamfered on an edge which projects into the trimming of the cleaning roller unit and which faces the entrance mouth. This results in a

Protection of stocking fibers. Furthermore, the rotational drive of the

Operate cleaning roller unit energy-saving. It is particularly advantageous if the stripping guide protrudes with a depth of at least 5% of a thickness of the stocking in the stocking, based on a wet stocking. It is basically possible for the wiping guide to be arranged on a cleaning roller holder. In one embodiment, the wiper guide is disposed on the dirty fluid tank means and removable with the dirty fluid tank means from the cleaning head. When the dirt fluid tank device is positioned at a holding position on the cleaning head, the wiping guide is then automatically defined "correctly" positioned relative to the cleaning roller unit.

In particular, the wiping guide device is formed by one or more edge elements, that is to say formed by one or more strips, which have corresponding edges which can protrude in particular into the trim of the cleaning roller unit. Preferably, an edge element at least partially forms a wall of the entrance mouth. It is also advantageous if a sweeping element is arranged on the cleaning head, through which the cleaning roller unit coarse dirt can be supplied for driving through the cleaning roller unit.

In particular, an inlet mouth of the dirty fluid tank means is positioned between the scraper guide and the sweeper.

As a result, coarse dirt, which has been supplied via the sweeping element of the cleaning roller unit, can be taken along by the cleaning roller unit and scraped off at the wiper guide device. It is particularly advantageous if a battery device and in particular a rechargeable battery device for supplying the drive motor with electrical energy is provided. As a result, the surface cleaning machine can be operated independently of the power supply. This results in a simple operation.

It is also advantageous if the drive motor is arranged between the battery device and the cleaning head. This results in an optimized positioning of the battery device. It is also advantageous if a tank device is provided for cleaning fluid. It can thereby moisten the surface to be cleaned directly or indirectly (by moistening the cleaning roller unit). The cleaning liquid is in particular water, to which a chemical cleaning agent can be admixed. The cleaning liquid makes it possible to moisten dirt on the surface to be cleaned in order to obtain improved solubility. In a structurally simple embodiment, the cleaning liquid tank means is positioned above the cleaning roller unit with respect to the direction of gravity when the surface cleaning machine is operated in a proper cleaning operation with the cleaning roller unit mounted on the surface to be cleaned. A supply of cleaning liquid to the cleaning head and in particular to the cleaning roller unit then takes place solely under the action of gravity. There is no need to provide an additional pump for pumping cleaning fluid. It is favorable if an inlet mouth of the dirty fluid tank device has a longitudinal extension direction, which is oriented parallel to a rotation axis of the cleaning roller unit. As a result, dirt fluid can be coupled into the dirty fluid tank device over a large length range.

The surface cleaning machine is designed in particular as a hand-operated or hand-guided surface cleaning machine. Due to the support via the cleaning roller unit on the surface to be cleaned, an operator can hold the surface cleaning machine at an end facing away from the cleaning head (so that it can not tip over) and guide it on the surface to be cleaned. The following description of preferred embodiments is used in conjunction with the drawings for further explanation of the invention.

Partial view is shown and designated 10, is designed in particular as a hand-held and hand-held floor cleaning machine for hard floors.

The surface cleaning machine 10 comprises a device body 12 and a cleaning head 14. The cleaning head 14 is arranged on the device body 12.

In a cleaning operation on a surface 16 to be cleaned, the surface cleaning machine 10 is supported by a cleaning roller unit 18 and in particular a single cleaning roller unit 18 on the surface 16 to be cleaned. The cleaning roller unit 18 has a single axis of rotation (see below). The cleaning roller unit 18 is a cleaning roller which may be one-piece or multi-piece. In the embodiment described below, the cleaning roller unit 18 is a two-part one

Cleaning roller.

The device body 12 has a longitudinal axis 20. The surface cleaning machine 10 is stalked or stalk guided. For this purpose, a holding rod device 22 is seated on the device body 12. In one exemplary embodiment, the holding rod device 22 comprises a (in particular exactly one) holding rod 24, which has a longitudinal extent parallel to the longitudinal axis 20. At an upper portion of the holding rod device 22, a handle 26 and in particular a bow handle is arranged. An operator can hold on this handle 26 with one hand the surface cleaning machine 10 and on the surface to be cleaned 16 (with mounted cleaning roller unit 18) lead. The holding rod device 22 may be designed to be variable in length or length-fixed with respect to a length in the longitudinal axis 20.

The surface cleaning machine 10 is dimensioned such that when the cleaning roller unit 18 is supported on the surface 16 to be cleaned, an operator can conveniently perform a cleaning operation on the surface 16 to be cleaned with an angled support arm. In particular, a length of the surface cleaning machine 10 in the longitudinal axis 20 between the cleaning roller unit 18 and the strap handle 26 is in a range between 60 cm and 130 cm.

On the handle 26 in particular one or more operating elements are arranged. For example, a switch is arranged, via which the surface cleaning machine 10 can be switched on or switched off for a cleaning operation. By this switch, the operation of a drive motor 28 for a rotational operation of the cleaning roller unit 18 is switchable. Furthermore, a switch for actuating a valve device 38 (see below) may be provided. The device body 12 comprises a housing 30 in which components of the surface cleaning machine 10 are arranged protected.

On the housing 30, a holder 32 is arranged. On the holder 32, a tank means 34 for cleaning liquid (in particular water with or without an additional cleaning agent) is removably arranged.

On the housing 30, a tank receptacle 36 for the tank device 34 is arranged on the holder 32. A corresponding outlet of the tank device 34 can be connected to the tank receptacle 36.

In the housing 30, the tank receptacle 36 is positioned downstream of a valve device 38. From the valve device 38, one or more fluid lines 40 lead to the cleaning head 14.

The valve device 38 has a shut-off valve, via which the supply of cleaning fluid from the tank means 34 to the cleaning head 14 is switchable lockable. The valve device 38 may be associated with a filter device 39 for cleaning fluid. The filter device 39 is in particular connected upstream of the check valve and arranged between the valve device 38 and the tank receptacle 36.

When the shut-off valve is open, cleaning liquid can flow out of the tank device 34 through the fluid line or fluid lines 40 to the cleaning head 14 and act on the surface 16 to be cleaned. For this purpose, one or more outlet openings for cleaning liquid are provided on the cleaning head 14. It is in principle possible that the outlet or outlet orifices are arranged so that the surface to be cleaned 16 is applied directly with cleaning liquid. In an advantageous variant, the outlet or outlet orifices are arranged so that the cleaning roller unit 18 and in particular a stocking 42 of the cleaning roller unit 18 is supplied with cleaning liquid. When the cleaning roller unit 18 is acted upon by cleaning fluid, the surface 16 to be cleaned is then indirectly exposed to cleaning fluid.

The trim 42 is made in particular of a textile material.

The valve means 38 is associated with a switch by which the user can set whether the check valve of the valve means 38 is locked (that is, the inflow of cleaning liquid to the cleaning head 14 is locked), or whether the check valve is open (that is, the inflow for Cleaning fluid from the tank means 34 is released to the cleaning head 14).

This switch can be arranged on the housing 30. It is also possible in principle that the switch is arranged on the handle 26.

In one embodiment, a battery device 44 for the electrical power supply of the drive motor 28 is arranged in the housing 30. The battery device 44 is rechargeable. As a result, the surface cleaning machine 10 can be operated independently of a mains supply.

But it is also possible in principle that the surface cleaning machine 10 is operated by mains power. It is then arranged a corresponding connection device for mains power to the surface cleaning machine 10.

The battery device 44 may be removable from the device body 12 in order to perform a recharging on a corresponding charger. It can also be provided that a corresponding charging device is integrated into the device body 12 and recharging is possible without removal of the battery device 44 from the device body 12. Corresponding connection sockets are arranged for example on the support rod 24.

The drive motor 28 is an electric motor. It has a motor shaft 46. The motor shaft 46 is coaxial with a rotation axis of the drive motor 28.

The drive motor 28 is seated between the cleaning head 14 and the housing 30 on the device body 12.

In one embodiment, the motor shaft 46 is oriented at an angle to the longitudinal axis 20 of the tool body 12 (and the support rod 24). Of the Angle between the motor axis 46 and the longitudinal axis 20 is for example in the range between 150 ° and 170 °.

In one embodiment, the cleaning head 14 is pivotable about a pivot axis 48 (see Figures 2 and 3) with respect to the apparatus body 12. This pivoting is shown in Figure 2 by the double arrow with the

Reference numeral 50 indicated.

In particular, the pivot axis 48 is coaxial with the motor axis 46.

In one embodiment, the drive motor 28 is disposed on an inner sleeve 52. The inner sleeve 52 is seated in the outer sleeve 54. The inner sleeve 52 is pivotable about the pivot axis 48 relative to the outer sleeve 54, wherein the inner sleeve 52nd is pivotally mounted in the outer sleeve 54. The inner sleeve 52 and the outer sleeve 54 form a pivot bearing 56 for the pivoting of the cleaning head 14 relative to the device body 12. The drive motor 28 is pivotable about the pivot axis 48 relative to the device body 12. Respective supply lines from the battery device 44 to the drive motor 28 are arranged and adapted to allow the pivoting. Accordingly, the fluid line 40 or the fluid lines 40 are designed so that they allow this pivoting.

The pivot bearing 56 has a basic position, which is defined, for example, in that (the only) an axis of rotation 58 of the cleaning roller unit 18 is oriented perpendicular to the plane E according to FIG. A pivoting about the pivot axis 58 relative to this basic position is expressed in an angular position of the rotation axis 58 to the plane E. The pivot bearing 56 is set in particular such that a relative to a normal cleaning operation requires special effort to effect a pivoting of the cleaning head 14 from its normal position.

The pivotability of the cleaning head 14 about the pivot axis 48 allows improved cleaning options even in less accessible places, as it were, the device body 12 with the Haltestabein- device 22 relative to the surface to be cleaned 16 can be "repositioned".

The cleaning head 14 has a cleaning roller holder 60, on which the cleaning roller unit 18 is rotatable about the rotation axis 58. The cleaning roller holder 60 is non-rotatably connected to the inner sleeve 52 connected.

The cleaning roller holder 60 has a holding region 62 for the cleaning roller unit 18, and a receiving chamber 64 for a dirty fluid tank device 66 (cf., for example, FIG.

The receiving chamber 64 is positioned between the holding portion 62 and the inner sleeve 52. The inner sleeve 52 is in particular fixedly connected to an outer side of the receiving chamber 64. The cleaning roller unit 18 is torque-effectively coupled to the drive motor 28 via a transmission device 68.

The transmission device 68 operatively connects a motor shaft of the drive motor 28 (which rotates about the motor axis 46) to a shaft 70 for the cleaning roller unit 18.

The transmission device 68 comprises in one embodiment a speed reducer. This serves to reduce a speed in Comparison with the speed of the motor shaft. For example, a standard electric motor has speeds of the order of 7000 revolutions per minute. The speed reducer reduces the speed to, for example, about 400 revolutions per minute.

The speed reducer may be disposed in the inner sleeve 52 or outside the inner sleeve 52 on the cleaning roller holder 60.

The speed reducer is designed, for example, as a planetary gear.

The transmission device 68 further comprises an angle gear, which provides for a torque deflection, to cause a drive of the cleaning roller unit 18 with the rotation axis 58 transversely (and in particular perpendicular) to the motor axis 46. The angular gear is in particular downstream of the speed reducer.

In one embodiment, the angular gear on one or more gears, which are rotatably coupled to a corresponding shaft of the speed reducer. These act on a bevel gear for angular conversion.

The transmission device 68 further includes, in one embodiment, a belt which is torque-operatively coupled to the bevel gear and acts on the shaft 70. The belt bridges the distance between the shaft 70 and the bevel gear and provides a speed reduction.

In one embodiment, the cleaning roller unit 18 is formed in two parts with a first part 72 and a second part 74. The first part 72 is non-rotatably mounted on a first side of the shaft 70 and the second part 74 is non-rotatably seated on one of the first side of the shaft 70 opposite the second Page. In an intermediate region 76 between the first part 72 and the second part 74, the transmission device 68 is guided and coupled to the shaft 70. They have the same axis of rotation 58.

The cleaning roller unit 18 or the first part 72 and the second part 74 of the cleaning roller unit 18 have a sleeve 78 (cf., for example, FIG. 5), which is cylindrical. On the sleeve 78 of the stocking 42 is arranged. About the sleeve 78, the cleaning roller unit 18 and the first part 72 and the second part 74 is fixed to the shaft 70.

The cleaning roller unit 18 is arranged on the cleaning head 14 such that the rotation axis 58 is oriented perpendicular to the longitudinal axis 20.

The cleaning roller unit 18 has a length along the rotation axis 58 between a first end face 80 (which is formed on the first part 72) and a second end face 82 (which is formed on the second part 74), which is considerably larger than a corresponding width of the device body 12 perpendicular to the longitudinal axis 20. In particular, a length of the cleaning roller unit 18 between the first end face 80 and the second end face 82 is at least 20 cm and preferably at least 25 cm.

The receiving chamber 64 has a bottom 84 (see, for example, Figure 5). On the floor 84, a receiving chamber wall 86 is arranged transversely oriented to this. The receiving chamber wall 86 and the bottom 84 of the receiving chamber 64 define a receiving space 88 for the

Dirt fluid tank 66. Opposite the floor 84, the receiving space 88 is open. Via a corresponding side 90, the dirty fluid tank device 66 can be removed from the receiving space 88 or inserted into it. A removal direction or insertion direction 92 (see FIG Substantially perpendicular to the bottom 84 (and perpendicular to the axis of rotation 58).

In one embodiment, the receiving chamber wall 86 has a step 96 at a wall portion 94 of the receiving chamber wall 86. The wall region 94 in this case faces the holding region 62.

The step 96 is further disposed near the bottom 84. The receiving chamber 64 is associated with a fixing device 98, via which the Schmutzfluidtankeinrichtung 66 can be fixed to the receiving chamber wall 86 in a holding position 100 (Figure 5). The fixation is done in particular by positive locking. In one embodiment, the fixing device 98 comprises a flap 102, which is arranged pivotably about a pivot axis 104 by means of a pivot bearing 106 on the cleaning head 14. The pivot bearing 106 is positioned at or in the vicinity of the inner sleeve 52. The pivot axis 104 is oriented parallel to the rotation axis 58 of the rotation roller 18.

In the stop position 100, the flap 102 acts on the dirty fluid tank 66 and holds it against the receiving chamber 64 in the receiving space 88.

To remove the dirty fluid tank device 66 from the cleaning head 14, the flap 102 is pivotable in the direction of the device body 12 (see FIG the removal direction 92 on the side 90 is removable from the receiving space 88 and is removable from the cleaning head 14. The Schmutzfluidtankeinrichtung 66 (Figures 8 to 10) is formed as a unit. It has a first chamber 110, which is assigned to the first part 72 of the cleaning roller unit 18, and has a second chamber 112, which is assigned to the second part 74 of the cleaning roller unit 18.

The first chamber 110 receives dirt fluid originating from the first part 72 of the cleaning roller unit 18, and the second chamber 112 receives dirt fluid coming from the second part 74 of the cleaning roller unit 18.

It is in principle possible for the first chamber 110 and the second chamber 112 to be connected to one another in a fluid-efficient manner, and in this case, for example, to be connected to a common discharge opening in a fluid-efficient manner.

It can also be provided that the first chamber 110 and the second chamber 112 are fluid-tightly separated from one another and each chamber 110, 112 has its own outlet opening.

The first chamber 110 and the second chamber 112 are spaced apart;

between the first chamber 110 and the second chamber 112, the Schmutzfluidtankeinrichtung 66 has a recess 114. The recess 114 is arranged relative to a longitudinal extension axis 116 of the dirty fluid tank device 66 in a middle region of the dirty fluid tank device 66.

When the dirty fluid tank device 66 is fixed to the cleaning head 14 in the holding position 100, the longitudinal extension axis 116 is oriented parallel to the rotation axis 58 of the cleaning roller unit 18.

The longitudinal axis 116 of the dirty fluid tank means 66 extends between a first outer end 118 and a second outer end 120 of the dirty fluid tank 66 with the dirty fluid tank 66 between the first outer end 118 and the second outer end 120 having their largest length dimensions. The recess 114 is used to carry out at least a portion of the transmission device 68. The cleaning roller unit 18 is driven centrally. The transmission device 68 bridges the distance between the drive motor 28 and the shaft 70. The recess 114 saves on the dirty fluid tank device 86 to a certain extent the space region which receives the transmission device 68.

It can be provided that the receiving chamber 64 has a respective receiving space 88 for the first chamber 110 and the second chamber 112.

It is also possible that a common receiving space 88 is provided for the first chamber 110 and the second chamber 112.

The first chamber 110 and the second chamber 112 are connected to each other via a bridge 122, so that the dirty fluid tank device 66 forms a unit and as a whole is removable from the cleaning head 14 or can be inserted into it.

In one embodiment, the dirty fluid tank means 66 includes a lid flap 124 pivotally seated over spaced pivot bearings 126a, 126b on the first chamber 110 and the second chamber 112.

The lid flap 124 can be opened to provide a corresponding discharge opening for the first chamber 110 and the second chamber 112 and, if appropriate, to be able to clean the dirty fluid tank device 66 in an interior space. In an embodiment shown in FIGS. 8-10, the first chamber 110 and the second chamber 112 are fluid tightly isolated from one another. The lid flap 124 is a common lid flap for both the first chamber 110 and the second chamber 112. By opening the lid flap 124, both the first chamber 110 and the second chamber 112 can then be emptied or access to the first chamber 110 and the second chamber 112 to perform a corresponding cleaning. The lid flap is with the first chamber 110 and / or the second

Chamber 112 and / or the bridge 122 can be fixed such that when the lid flap 124 is closed, a fluid-tight dirty fluid tank means 66 (except for an inlet mouth) is provided. It is fundamentally possible for the dirty fluid tank device 66 to also comprise mechanically separate chambers, with one chamber then being assigned to the first part 72 and the second part 74 of the cleaning roller unit 18. In this case, the corresponding parts of the dirty fluid tank device must then be removed or used separately from the cleaning head 14.

The Schmutzfluidtankeinrichtung 66 has an underside 128 which is formed on an outer side of the bottom 84 respectively to the first chamber 110 and to the second chamber 112. It also has an underside 128 opposite top 130, which is formed on an outer side of the lid flap 124.

On the upper side 130 of the dirty fluid tank device 66 and thus on the cover flap 124, a recess 132 (or a plurality of recesses 132) is formed. The recess or recesses 132 are channel-shaped and have an undercut surface 134. The flap 102 has a counter element 136 (or a plurality of counter elements 136), which serve for cooperation with the recess 132.

A blocking element 138 is arranged on the counter element 136 or the counter elements 136 (FIGS. 5 to 7), which serves for cooperation with the undercut surface 134. When the counter element 136 is immersed with its blocking element 138 in the recess 132 and the holding position 100 is reached, then the blocking element 138 bears against the undercut surface 134. As a result, the flap 102 is blocked from pivoting away from the upper side 130 of the dirty fluid tank device 66. A corresponding force must be applied to guide the blocking element 138 away from the undercut surface 134.

The dirty fluid tank 66 is positioned relative to the flap 102 and the receiving chamber 64 such that when the dirty fluid tank 66 is positioned in the holding position 100 on the receiving chamber 64, the blocking element 138 is immersed in the recess 132 and abuts the undercut surface 134 accordingly and thus the holding position 100 secures.

In one embodiment, the dirty fluid tank 66 has a stage 140 adapted to the stage 96 (see, for example, Figure 6).

When the dirty fluid tank 66 is inserted into the receiving space 88, the receiving chamber wall 86 blocks mobility of the dirty fluid tank 66 in the receiving space 88 in the transverse directions to the removing / inserting direction 92.

This positive locking is optionally supported by the steps 96, 140.

The bottom 84 of the receiving chamber 64 prevents "dousing" the Schmutzfluidtankeinrichtung 66 during insertion. When the flap 102 is closed and the blocking element 138 is positioned in the recess 132 against the undercut surface 134, movement is blocked parallel to the withdrawal direction 92 about the holding position 100 of the dirty fluid tank device 66 on the receiving chamber 64.

The flap 102 is designed in particular as a hold-down device, which ensures a defined positioning of the dirty fluid tank device 66 in relation to the cleaning roller unit 18.

The flap 102 is in particular so elastically arranged or formed that in the holding position 100, the flap 102 exerts a corresponding positioning force and in particular the Schmutzfluidtankein- direction 66 against the bottom 84 and the wall portion 94 is pressed. The pressing against the wall portion 94 is also by

Cooperation of the stage 96 to the wall portion 94 with the stage 140 in the Schmutzfluidtankeinrichtung 66 supports. It can be provided that the flap 102, for example, on the

Swivel bearing 106 is spring-supported. Alternatively or additionally, the flap 102 may be formed, for example, on the counter element 136 such that a corresponding elastic force can be exerted on the dirty fluid tank device 66.

The cleaning head 14 has a scraper guide 142 (see Fig. 5) which acts on the cleaning roller unit 18 (and thereby on the first part 72 and the second part 74) and serves to remove dirt fluid (in particular water) entrained by the cleaning roller unit 18 with dirt particles) and to feed an inlet mouth 144 of the dirty fluid tank device 66, which is fixed in the holding position 100 to the cleaning head 14. As a result, dirt fluid is then coupled into the dirty fluid tank device 66. The inlet mouth 144 of the dirty fluid tank device 66 has a slot-like design (FIG. 9). It includes a first portion 146, which is an entrance mouth for the first chamber 110, and includes a second portion 148, which is an entrance mouth for the second chamber 112.

In the exemplary embodiment shown in FIG. 9, the first part 146 and the second part 148 each have a greater length in the longitudinal extension axis 116 than the associated chamber 110 or 112. The dirty fluid tank device 66 has at the end of the inlet opening 144 on the first part 146 and at the second part 148, a respective wall to about the first part 146 and the second part 148 of the inlet mouth 144 collected dirt fluid each of the first chamber 110th

or the second chamber 112 to be able to supply.

The first part 146 of the inlet mouth 144 is associated with the first part 72 of the cleaning roller unit 18. The second part 148 of the inlet mouth 144 is assigned to the second part 74 of the cleaning roller unit 18. The first part 146 and the second part 148 of the inlet mouth 144 are spaced from each other according to the spacing of the first part 72 and the second part 74.

Preferably, the first part 146 and the second part 148 each have a length in the longitudinal extension axis 116, which at least

Approximately corresponds to a corresponding stocking length of the first part 72 and the second part 74 of the cleaning roller unit 18 along the axis of rotation 58.

The scraper diverter 142 is configured to scrape dirt fluid therefrom from the cleaning roller unit 18 and into the entrance mouth 144. It is possible that when rotating cleaning roller unit 18, a conductive effect on the effect of the centrifugal force is achieved and to some extent dirt fluid is thrown into the Schmutzfluidtankeinrichtung 66. The scraper guide 142 is spaced from the axis of rotation 58.

In one embodiment (cf., for example, FIG. 5), the wiping guide device 142 protrudes with a depth T into the stocking 42 of the cleaning roller unit 18. The depth T is in particular at least 5% of a thickness D (FIG. 5) of the stocking 42 of the cleaning roller unit 18 based on a wet condition of the stocking 42.

The wiping guide 142 is in particular formed by one or more edge elements 150. For example, the first part 72 and the second part 74 of the cleaning roller unit 18 is associated with a respective edge element 150.

An edge element 150 is designed as a strip, which protrudes into the stocking 42 of the cleaning roller unit 18 on the first part 72 and the second part 74 accordingly.

The edge element 150 has a relatively small thickness, which in particular is smaller than a thickness D of the trim 42. In one embodiment, the edge element 150 or the edge elements 150 are formed curved.

The scraper guide 142 with the edge member 150 or the

Edge elements 150 form in particular a wall of the inlet mouth 144.

The edge element or elements 150 are rounded or chamfered at an edge which faces the entrance mouth 144. Thereby fibers of the stocking 42 are spared and it must be overcome in the rotation of the cleaning roller unit 18 a small force. This in turn achieves an energy-saving effect. This rounding at the edge is indicated by the reference numeral 151 in FIG.

It may in principle be provided that the wiping guide 142 is arranged on the cleaning roller holder 60.

In the embodiment shown, the scraper guide 142 is seated on the dirty fluid tank 66.

This has a wall 152, which faces the wall region 94 in the holding position 100. The edge element (s) 150 are disposed on the corresponding wall 152 of the first chamber 110 and the second chamber 112.

The corresponding stripping guide device 142 is preferably arranged outside the cover flap 124 of the dirty fluid tank device 66. In this embodiment, the scraper guide 142 is removed from the cleaning head 14 when the dirty fluid tank 66 is removed therefrom.

It is further provided that a cover 154 is positioned on the cleaning head 14 of the cleaning roller unit 18. The cover 154 is subsequently disposed of the stripper baffle 142 (with the edge element (s) 150). The edge element 150 is curved so that it is adapted to a corresponding curvature of the cleaning roller unit 118 with the stocking 42.

Basically, the cover 154 may touch or penetrate the trim 42, preferably penetrating to a lesser depth than the penetration of the scraper guide 142 across the depth T. In one embodiment, the fluid line 40 opens or open the fluid lines 40 in a region 156 between the cover 154 and the scraper-guide 142. In this area, the cleaning roller unit 18 can be acted upon with cleaning liquid from the tank means 34.

In particular, the region 146 has a length along the rotation axis 58 which corresponds at least approximately to a corresponding length of the first part 72 and the second part 74 of the cleaning roller unit 18, respectively, to allow a uniform liquid loading of the cleaning roller unit 18 over its length.

In the embodiment shown, the cover 154 is at the

Schmutzfiuidtankeinrichtung 66 arranged.

It must then be taken to ensure that a suitable coupling of the fluid line 40 or fluid lines 40 is reached. Based on a rotational direction 158 (see FIG. 5) of the cleaning roller unit 18 in a cleaning operation, the wiping guide 142 with its edge element 150 or its edge elements 150 is arranged downstream of the inlet mouth 144. This is a "slinging" of dirty fluid, which was previously taken by the cleaning roller unit 18 from the surface to be cleaned 16 and was transported in the direction of the stripping guide 142, via the scraper-guide 142 in the inlet mouth 144 and thereby in the Schmutzfiuidtankeinrichtung 66 allows. The cleaning roller unit 18 is in one embodiment further associated with a sweeping element 160, which serves to coarse dirt of the

To supply cleaning roller unit 18. This can then with the

Cleaning roller unit 18 are taken. The entrance port 144 is disposed between the stripper baffle 142 on the sweeping element 160. In the embodiment shown, the sweeping element 160 is positioned on the cleaning roller holder 60 at the holding portion 62. The sweeping element 160 is designed so that it at least in an angular position range (if the surface cleaning machine 10 is not too steep) of the surface cleaning machine 10 with respect to the longitudinal axis 20 to the surface 16 to be cleaned on the surface 16 to be cleaned for the Can act sweeping function.

The sweeping element 160 is for example arranged pivotably on the cleaning roller holder 60 and / or it is designed to be elastic.

In particular, the sweeping element 160 projects into the stocking 42 of the cleaning roller unit 18. However, it can also touch the stocking 42 or be spaced apart from it. Based on the direction of rotation 158 of the cleaning roller unit 18, when it is driven by the drive motor 28 in its rotational movement, the sweeping element 160, followed by a guide portion 162 of the cleaning roller holder 60, which in its form (hollow) cylindrical follows on the surface 16 to be cleaned and is adapted to the cleaning roller unit 18, then the entrance mouth 144, thereon the wiper guide 142 with the edge element (s) 150 and then the cover 154, the area 156 between the cover 154 and the wiper guide 142. In the embodiment shown, the surface cleaning machine 10 is formed without a suction fan. Dirt fluid, which is entrained by the cleaning roller unit 18 is not sucked by an additional suction fan in the dirty fluid tank means 66, but the Wiper guide 142 alone ensures that dirty fluid is coupled into the dirty fluid tank means 66.

In principle, it is also possible that the coupling is still supported by an additional suction fan.

The surface cleaning machine 10 works as follows:

In a cleaning operation, the dirty fluid tank device 66 is fixed to the cleaning head 14 in the holding position 100.

For a cleaning process, the surface cleaning machine 10 is placed alone on the cleaning roller unit 18 on the surface 16 to be cleaned. The drive motor 28 drives the cleaning roller unit 18 in a rotational movement about the (single) rotation axis 58 in the direction of rotation 158.

The cleaning roller unit 18 is supplied with cleaning fluid from the tank device 34.

Dirt on the surface 16 to be cleaned is moistened when the moistened stocking 42 of the cleaning roller unit 18 acts on it to facilitate its releasability. The rotation of the cleaning roller unit 18 causes a mechanical action on dirt on the surface 16 to be cleaned in order to obtain better detachability from the surface 16 to be cleaned.

Any coarse dirt can be supplied to the cleaning roller unit 18 with the sweeping element 160.

Dirt fluid (dirt particles, cleaning liquid with dissolved dirt) is taken along by the cleaning roller unit 18 and removed at the stripping Conductor 142, the dirty fluid from the cleaning roller unit 18 is released and (among other things under the action of centrifugal force) into the inlet port 144 and passes from there into the Schmutzfiuidtankeinrichtung 66. The stripping guide 142 provides by stripping for a solution of dirt fluid from the stocking 42th the cleaning roller unit 18.

The coupling of dirt fluid into the Schmutzfiuidtankeinrichtung 66 takes place in particular without suction fan. The dirty fluid tank 66 is detachably positioned on the cleaning head 14.

The flap 102 provides a backup of the stop position 100. In the stop position 100, the inlet mouth 144 of the dirty fluid tank 66 is also aligned relative to the cleaning roller unit 18 in relation to the wiper guide 142 so that the corresponding release function and engagement function is achieved as described above.

The flap 102, with its function as a hold-down device, ensures that the edge element 150 or the edge elements 150 with the depth T are correspondingly pressed into the stocking 42 in order to achieve an optimum stripping function by stripping.

In particular, the scraper guide device 142 is arranged on the dirty fluid tank device 66 and can be removed therefrom by the cleaning head 14.

The flap 102 presses with its counter element 136 and the blocking element 138 disposed thereon on the top side 130 of the dirty fluid tank device 66 and thereby secures the holding position in which the above-described relative positioning of the scraper guide device 142 to the cleaning roller unit 18 is achieved. A positive retention of the dirty fluid tank device 66 on the receiving chamber 64 in the holding position 100 is provided.

To remove the dirty fluid tank device 66 (FIG. 3, FIGS. 6, 7), the flap 102 is opened. It is pivoted in the direction of the device body 12. In order to guide the blocking element 138 out of the recess 132 with the undercut surface 134, a corresponding elastic deformation of the counter element 136 must be carried out. When the flap 102 (FIG. 6) is completely open, the dirty fluid tank 66 can then be removed (compare FIG. 3).

By opening the cover flap 124 of the dirty fluid tank device 66, it can be emptied and optionally cleaned, for example, by rinsing.

For example, the dirty fluid tank 66 has a capacity of about 150 ml. The surface cleaning machine 10 has a relatively low energy requirement, since no suction fan must be provided and dirt fluid is coupled directly from the cleaning roller unit 18 with "minimized path" in the Schmutzfluidtankeinrichtung 66. The surface cleaning machine 10 can therefore be operated optimally with a rechargeable battery device 44.

The surface cleaning machine according to the invention makes it possible to carry out a wet cleaning of hard floors with a high degree of automation. The force required during wiping is reduced or eliminated by the mechanical support via the driven rotation roller 18. The moistening of the cleaning roller unit 18 makes it possible Operator to perform a cleaning operation without having to

Dirt fluid comes into contact.

In addition, in a cleaning operation, self-cleaning of the cleaning roller unit 18 follows to some extent.

The dirty fluid tank 66 is disposed between the cleaning roller unit 18 and the drive motor 28. A longitudinal direction of the inlet mouth 144, which is parallel to the longitudinal axis 116, is parallel to the axis of rotation 58 of the cleaning roller unit 18 and transversely and in particular perpendicular to the motor axis 46. Further, this longitudinal axis of the entrance mouth 144 is transverse and in particular perpendicular to the longitudinal axis 20. It can It is also contemplated that the drive motor 28 may be utilized to drive one or more suction turbines that are respectively in fluid communication with an interior of the dirty fluid tank 66 to create a vacuum that enhances the introduction of dirty fluid into the dirty fluid tank.

In principle, the surface cleaning machine 10 can also be operated in network operation.

The sweeping element 160 can also be arranged on the dirty fluid tank device 66.

It may be provided an overload protection. This is designed for example as a mechanical overload protection, which includes, for example, a slip clutch. Alternatively or additionally, an electronic overload protection may be provided which, for example, performs an overcurrent shutdown. In a normal cleaning operation, the tank device 34 is arranged above the cleaning head 14 with respect to the direction of gravity.

As a result, cleaning fluid can flow under the effect of gravity from the tank device 34 to the cleaning head 14 in a pump-free manner in order to act on the surface 16 to be cleaned directly or indirectly via the cleaning roller unit 18 with cleaning fluid.

The surface cleaning machine 10 may be designed so that the sweeping element 160 is effective only when a certain angular position is adjusted relative to the longitudinal axis 20 to the surface 16 to be cleaned and in particular an angle between the surface 16 to be cleaned and the longitudinal axis below a Maximum angle is.
