Abstract

The invention relates to a carpet cleaning device (1), especially a sweeper or a carpet brush, with a device for removing dust, soiling particles or the like from a surface to be cleaned, especially sweeping units, preferably in the form of sweeping brushes (2) and a collecting chamber (3) for soiling removed. In order to obtain easy and especially hygienic operation with the simplest possible structure, the invention proposes that the cleaning device (1) be connectable to a suction device (12) to empty the collecting chamber (3).

Description

00001 cleaning device 00002 00003 The invention relates to a cleaning device, in particular 00004 re a sweeper, for example a carpet sweeper 00005 with a device for picking up dust, dirt 00006 parts or the like from a surface to be cleaned, for example 00007 sweeping elements, preferably in Form of brushes, and 00008 a holder for the dirt. 00009 00010 Cleaning devices of this type are known as carpet sweepers 00011 in various configurations. E.g. reference is to 00012 the German utility model 19 09 382. Such carpet sweepers have already become known with 00014 an electric drive, for which 00015, for example, the German utility model 75 34 321 and 75 36 00016 434 can be referred to. In the prior art 00017 reference is also made to DE-OS 29 43 201. In carpet sweepers of this type it is also known to collect the dirt collected in a separate receptacle 00020 me. To empty the holder, this 00021 can be removed from the device. Furthermore, vacuum cleaner devices are known, for which purpose reference is made only to 00024, for example, only DE-OS 39 11 580. Here, the said dirt is collected in a 00025 dust bag, which can be removed after opening the vacuum cleaner 00026 and can be disposed of altogether. There is a need to specify a cleaning device such as, in particular, a carpet sweeper, which, on the one hand, is not as complex and large as a vacuum cleaner, but on the other hand, if possible, the same 00032 same hygienic advantages with regard to disposal 00033 of the collected dirt. The technical 00034 problem is therefore given by further training a 00035 cleaning council of the type specified above.

REPLACEMENT SHEET (RULE 26) 00036 and design that with the simplest possible

00037 construction nevertheless an advantageous and in particular

00038 hygienic handling is given. 00039

00040 This technical problem is first and foremost

00041 essentially solved in the subject of claim 1,

00042 is based on the fact that the cleaning device for emptying the receptacle with a suction device

00044 device is interconnectable. The suction device can

00045, for example, can be a conventional vacuum cleaner. This creates a 00046 cleaning device, the inclusion of which, so to speak

00047 an interim storage facility for the collected dirt

00048 represents. The recording itself is preferably not public.

00049 can be opened or removed from the device. The emptying

00050 can only be connected by connecting a suction device, i.e.

00051 special of the usual vacuum cleaner. In advantageous

00052 can this cleaning device over a

00053 longer period and several cleaning processes

00054 can be used without it being necessary to

00055 advises to connect. If the suction device is used anyway,

00056 can also be used to empty the cleaning

00057 advises hereby to be made. Even the dirt that

00058 has been collected by the cleaning device

00059 in the usual way in the dust bag of a vacuum cleaner

00060 transported and can then be a total of the dust bag

00061 are disposed of in the usual way. An expensive one

00062 Device for attaching your own dust bag

00063 or the like on the cleaning device in question

00064 itself is not required. Here the cleaning

00065 power device motor-operated or only hand-operated

Be 00066. Engine operation can be used in particular for driving

00067 of the cleaning brushes can be provided. In another

Embodiment of the invention provides that the

00069 receiving chamber has a suction port for connection

00070 of the suction device. The suction nozzle is therefore 00071 bar coupled to the receiving chamber. As long as the suction device 00072 is not connected, the suction connector 00073 is of no importance. In detail, the receiving chamber 00074 can be designed in such a way that a trough-like receiving channel is formed following a 00075 inlet funnel, which in the case of sweeping brushes is formed in the 00076 tangential direction of ejection of the sweeping brushes. 00078 This receiving channel preferably extends 00079 to a direction in which the cleaning device 00080 is usually to be moved 00081 for cleaning purposes. It is also advantageous to arrange the receiving channel extending in 00082 substantially above the inlet funnel. Through the inlet funnel, the 00084 dirt particles thrown off by the brushes, for example, are directed upwards and deflected towards 00085, so that they then fall into the 00086 receiving channel. In a cross-section, the 00087 receiving chamber is compared with a corner housing. The inlet funnel also expediently extends essentially over the length of the receiving element 00090 ne and at the same time also over the length of the brushes, for example Kehr¬. The suction nozzle can advantageously open into a floor of the receiving channel in 00092. 00093 00094 The invention is further explained below with reference to the drawing 00095, which, however, only represents an exemplary embodiment. Here: 00097 00098 shows a cross-sectional view of the cleaning device with a dashed-on attached 00100 th suction device for emptying the receptacle; 00101 00102 Fig, a bottom view of the device according to Fig, 1, 00103 but without the suction device; 00104 00105 Fig. 3 is an isolated representation of the recording for

00123 Shown and described - initially with reference to

00124 Fig. 1 - a cleaning device 1 in the form of a carpet

00125 sweeper. The cleaning device here has brushes 2

00126, of which usually two individual brushes

00127 are arranged on a central drive.

00128 Furthermore, an electric motor is provided, which is individually

00129 NEN is not shown, for driving the sweeping brushes

00130 2. 00131

00132 The cleaning device 1 has a receptacle 3, in

00133 which dirt particles, dust etc., which by means of

00134 sweeping brushes 2 swept up, collected. In

00135 Fig. 1 is schematically in a receiving groove 4 of the

00136 receiving chamber 3 accumulated dirt 5 shown. 00137

00138 Next is the Aufnähmekämmer 3 with a suction port 6

00139 formed in a bottom of the receiving channel 4th 00140 flows. The bottom of the receiving channel 4 is therefore in the

00141 rich of the intake port 6 partially interrupted. The

00142 suction nozzle 6 can in the embodiment, in the middle

00143 with respect to a transverse extension (extension in the

00144 device of the longitudinal axes of the sweeping brushes 2) of the

00145 chamber 3 can be formed, but it can also, for example

00146 or assigned on both sides to the front ends

00147 of the receiving chamber 3 be formed and in contrast

00148 for the exemplary embodiment would be the bottom of the receiving

00149 ne 4 then with two-sided arrangement twice by each

00150 a suction port 6 interrupted. The suction nozzle can

00151 also attached directly to one or both faces

00152 locks. Here is an enforcement of

00153 floor not required. 00154

00155 The Aufnah ekammer 3 also has an inlet funnel

00156 7, which is in the direction of the sweeping brushes 2

00157 is assigned. The inlet funnel 7 is in its mouth

00158 area 8 formed with an opening height that is about

00159 corresponds to a radius of the carpet sweeping brushes 2. He

00160 then tapers and is curved up to

00161 a height h, in which an inner trough wall 9 den

00162 forms the end of the receiving channel 4. When executing

00163 example, the suction nozzle 6 passes through the inlet funnel

00164 ter 7 approximately in the middle based on a longitudinal or

00165 transverse extension of the inlet funnel 7 and the receptacle

00166 3 in total. The assertive ends in this area

00167 suction nozzle 6 in the inlet funnel 7 as it were

00168 flow divider. 00169

00170 It is also important that the receiving channel 4 above

00171 half of the inlet funnel 7 and to an opening of the

00172 inlet funnel 7 is arranged sunk. The up

00173 channel 4 is approximately assigned to a

00174 upper cross-sectional half of a brush 2. 00175 As from the cross-sectional view according to FIG. 1, however

00176 also the cross-sectional representations of FIGS. 5 and 6

00177 can be seen, the receiving funnel 7 is together

00178 with the receiving channel 4 as a whole

00179 designed like a house. 00180

00181 From the representations of FIGS. 1 and 2 further

00182 visible that the suction nozzle 6 in a Sauglei-

00183 device 10 opens out with a connecting piece 11 with

00184 a suction device shown only schematically, namely

00185 in particular a vacuum cleaner 12 can be connected. The

00186 connecting piece 11 can be closed. 00187

00188 It is also preferably provided in the drawing

00189 not shown in detail, however, that the muzzle

00190 opening 8 of the inlet funnel 7 by a blind

00191 is closable. This can cause a fall out of

00192 collected dirt, for example when the

00193 device to be avoided. 00194

00195 The design of the receiving chamber 3 is further in the

00196 individual from FIGS. 3 to 6 can be seen. 00197

00198 As can be seen in particular from the cross-sectional representation

00199 lung Fig. 5 results, is also the connection of the Saugkanal-

00200 les 6 together with the assigned part of the recording

00201 channel 4 and the upper one in the form of a circular arc

00202 gene end 13 trained like a worm gear. through

00203 locking means 14 can the receiving chamber 3 in the cleaning

00204 device 1 be locked. In particular,

00205 moves that the receiving chamber 3 cannot be released operationally

00206 is arranged in the cleaning device. 00207
