Description

TECHNICAL FIELD

The present invention relates to an apparatus for clothes, and more particularly, to a new clothes refresher capable of de-wrinkling and sterilizing clothes.

BACKGROUND ART

Generally, apparatuses for clothes are designed to perform a variety of operations associated with clothes. Examples of these apparatuses for clothes include a washing machine for washing clothes, a drying machine for drying wet clothes, and other various appliances.
Among the variety of apparatuses for clothes, the drying machine is adapted to perform a drying operation in a state wherein clothes are put in as one lump, and therefore, has a problem in that entangled portions of the clothes are difficult to be efficiently dried.
Furthermore, if the dried clothes are left in the drying machine for a long time, wrinkles of the clothes increase and deepen, resulting in a requirement of troublesome ironing. Accordingly, it is impossible to store clothes in the drying machine.
For these reasons, a recent trend requires a new drying apparatus capable of achieving an increase in drying capacity and enabling long term storage of clothes. U.S. Published Patent Applications Nos. US2004/0194339 A1 and US2004/0154194 A1 disclose dual type drying machines in which a drum type drying machine is provided with a separate drying cabinet.
The dual type drying machine is a drying appliance configured in such a fashion that the drying cabinet having a space for receiving a variety of clothes is mounted at an upper side of the drum type drying machine having a rotary drum, and the drying cabinet is configured to receive hot air.
If the hot air is supplied from the drum type drying machine to the drying cabinet, the drying cabinet is used to dry clothes received therein or to enable long term storage of the clothes.
The above described drying cabinet, however, has a problem in that it must be integrally formed with the drum type drying machine to perform a drying operation.
This is die to the fact that the drying cabinet can receive hot air only when it is coupled to the drum type drying machine.
For this reason, it is impossible to use the drying cabinet independently of the drum type drying machine, and the control of the drying cabinet is possible only when the overall power of the dual type drying machine is applied.
Moreover, the drying cabinet of the above described dual type drying machine has no refresh operation for de-wrinkling and sterilizing clothes, and therefore, is inappropriate for short term storage of clothes.

BEST MODE FOR CARRYING OUT THE INVENTION

Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.
Now, a refresher in accordance with a preferred embodiment of the present invention will be explained with reference to FIGS. 1 to 10.
As shown in FIGS. 1 and 2, the refresher basically comprises a base 100, a steam generator 200, a cover 300, and a body 400.
Here, the base 100 is configured to have a space for storing a predetermined amount of water required to generate steam.
Although not shown, it is desirable that the water storage space of the base 100 be formed with a discharge portion for discharging the water, which remains after completing a refresh operation, to the outside. Preferably, the discharge portion is located at a lower surface of the base 100. More preferably, the discharge portion is provided with a valve, which is designed to be electrically opened and closed.
In particular, it is desirable that the base 100 be further formed with an inlet opening 110 to introduce water into the water storage space.
Preferably, the inlet opening 110 is formed at a position approximately higher than an appropriate level of water stored in the water storage space. This is for the sake of preventing leakage of the water stored.
It is desirable that the base 100 be further provided with an inlet passage 120 between the inlet opening 110 and the water storage space. This is for the sake of achieving the accurate introduction of water.
The inlet opening 110 is preferably provided with an opening/closing door 130, to be selectively opened and closed.
The steam generator 200, which is one constituent element of the refresher, serves to selectively heat and evaporate the water stored in the base 100.
The steam generator 200 includes a heat-radiating heater 210, and a controller 220.
The heat-radiating heater 210 is installed such that one end thereof is located in the water storage space of the base 100 and the other end thereof, which is formed with a terminal, is located at the outside of the water storage space.
In this case, it is desirable that a region of the heat-radiating heater 210, where the terminal is formed, be provided with a packing 211 for preventing leakage of water.
In particular, the heat-radiating heater 210 may be preferably a sheath heater. Here, the sheath heater means a heater wherein a coil thereof is surrounded by a highly heat conductive material, such as for example, aluminum or copper, so as not to be exposed to the outside. This is for the sake of preventing the coil from being brought into contact with the stored water.
The controller 220 is located in an inner space of the base 100 separated from the water storage space, and is adapted to control a heat-radiating operation of the heater 210.
Preferably, an operation panel 140 is provided at a front surface of the base 100 for manual control of the controller 220. The reason why the operation panel 140 is located at the front surface of the base 100 is to keep the operation panel 140 at a fixed position regardless of folding and unfolding operations of the body 400, and also, to ensure easy manual operation of the operation panel 140 regardless of the user's height.
In the case of the above described steam generator 200, if the level of water, stored in the water storage space of the base 100, drops below the lowest water level, the heat-radiating heater 210 is exposed to the outside, and this may result in a risk of fire.
For this reason, although not shown, it is desirable that the steam generator 200 or the base 100 contain at least one of a temperature sensor, humidity sensor, and water level sensor, in order to prevent the level of water from dropping below a pre-determined water level.
The cover 300, which is one constituent element of the refresher, serves to selectively close an upper surface of the base 100, and preferably, is configured to have a predetermined space therein.
A holder bar 310 is provided in the space of the cover 300 to hang a clothes hanger thereon. The holder bar 310 is connected at both ends thereof to two shorter side surfaces of the rectangular cover 300 facing each other.
Of course, it will be appreciated that both the ends of the holder bar 310 may be connected to opposite longer side surfaces of the cover 300 facing each other.
The cover 300 is preferably formed with an outlet opening 320 to discharge part of air or steam existing in the space of the cover 300.
The outlet opening 320 may take the form of a simple opening, but may be formed to be adjustable in the degree of opening thereof.
The body 400, which is one constituent element of the refresher, is connected between the base 100 and the cover 300. Preferably, the body 400 is made of a foldable flexible material.
In particular, the body 400 is configured to define a predetermined receiving space for receiving clothes, which will be subjected to a refresh operation, when it is unfolded. A surface of the body 400 is provided with a structure for selective opening of the receiving space.
The structure for opening and closing the receiving space of the body 400 may be preferably a zipper.
Such a structure for opening and closing the receiving space must allow a user to easily put clothes into the body 400 and take out the clothes from the body 400, and also, prevent steam present in the closed body 400 from leaking to the outside.
Of course, it will be appreciated that the structure for opening and closing the receiving space may be selected from among a variety of configurations other than the zipper.
In particular, when the body 400 is made of a flexible material, it is desirable that the refresher further comprise a supporter 500 to support the body 400 when the body 400 is completely unfolded, as shown in FIGS. 3 to 6.
The supporter 500 is preferably connected at both ends thereof to rear surfaces of both the base 100 and the cover 300 and adapted to be folded and unfolded like a link. Although not shown, it will be appreciated that the supporter 500 may take a telescopic configuration to be extendible and contractible in length thereof.
Hereinafter, the operational sequence of the refresher having the above described configuration will be explained.
First, in an initial state of the refresher, the cover 300 closes the upper surface of the base 100 as shown in FIGS. 1 to 3.
In such a closed state, the body 400 is hidden inside the cover 300 and the base 100 while being in a folded state.
Then, when it is intended to perform a clothes refresh operation, the cover 300 is opened away from the base 100.
In accordance with the opening operation of the cover 300, the body 400 is exposed from between the cover 300 and the base 100, and is gradually unfolded.
Referring to FIGS. 4 to 6, the body 400 is shown in a completely unfolded state.
After being completely unfolded, the body 400 is able to be continuously kept in the unfolded state by the supporter 500.
Also, in the completely unfolded state of the body 400, the zipper is operated to open the inner surface of the body 400.
After clothes to be refreshed are hung on hangers, and in turn, the hangers are hung on the holder bar 310 inside the cover 300, the zipper is again operated to close the inner space of the body 400.
In this way, the clothes are received in the body 400.
After that, the controller 220 of the steam generator 200 is controlled to operate the heat-radiating heater 210.
If the heater 210 operates to radiate heat in accordance with the above described serial procedure, the water stored in the base 100 is heated and evaporated, resulting in generation of steam.
The steam generated as stated above rises from the inner space of the base 100, to be supplied into the body 400, and consequently, to be supplied to the clothes received in the body 400.
As a result, the clothes are able to be sterilized and de-wrinkled by the high-temperature steam, to accomplish a refresh operation of the clothes.
Since the inner space of the body 400 for receiving the clothes has a small volume, in particular, the refresh operation of the clothes can be performed within a short time. This has an advantage in that the clothes can be efficiently refreshed even if the storage time of the clothes is short.
Meanwhile, if the body 400 is still full of the steam after the refresh operation is performed in the middle of the above described serial procedure, the refreshed clothes may be wet by the steam.
For this reason, it is desirable that the outlet opening 320 formed at the cover 300 be opened if the refresh operation is performed.
In the above described refresher, meanwhile, the water storage space of the base 100 for receiving the water required to generate steam is configured to communicate with the inner space of the body 400, and therefore, there is a risk in that a lower end of the clothes may reach the water or the clothes may carelessly drop into the water when they are hung on the holder bar 310.
Furthermore, in a state wherein the cover 300 closes the base 100 as shown in FIG. 2, the body 400 may be wet by the water stored in the base 100.
Accordingly, the above described refresher needs a separate structure to solve the above described problems. To comply with this necessity, the refresher of the present invention may further comprise a partition 170 inside the base 100 as shown in FIGS. 7 and 8.
Preferably, the partition 170 is configured to separate the water storage space of the base 100 from a space above the water storage space while allowing the steam generated by the steam generator 200 to be efficiently supplied into the inner space of the body 400 where the clothes are received.
For this, the partition 170 may take the form of a lattice grill or mesh.
When the partition 170 takes the form of the lattice grill or mesh, the steam is able to be distributed throughout the partition 170, and therefore, is able to be uniformly supplied into the overall inner space of the body 400.
More preferably, the partition 170 may be detachably coupled to an inner wall surface of the base 100, for the sake of cleaning of the inner space of the base 100.
With the use of the partition 170, even in a state wherein the cover 300 closes the base 100, the body 400 is placed on the partition 170, thereby being kept in a stably folded state without a risk of being wet by the water stored in the base 100.
Also, in a state wherein the cover 300 opens the base 100, more particularly, in a state wherein the body 400 is unfolded for the use of the refresher as shown in FIG. 8, the partition 170 prevents the lower end of the clothes from reaching the water stored in the base 100.
Referring to FIG. 9, a blowing device 630 may be mounted at the cover 300, to facilitate efficient circulation of the steam in the inner space of the body 400.
The blowing device 630 is able to discharge air inside the body 400 to the outside, and to achieve efficient circulation of steam and air.
The reason why the blowing device 630 is provided at the cover 300 is to efficiently supply the steam generated to the uppermost space of the refresher in consideration of the fact that the steam is generated in the lowermost space of the refresher.
Referring to FIG. 10, a partition 821 having a plurality of injection nozzles 822 for the injection of steam may be provided.
The injection nozzles 822 are configured to protrude upward from the partition 821 by a predetermined height, and each has a hollow tubular form.
Preferably, the injection nozzle 822, having the hollow tubular form, gradually decreases in an inner diameter toward an upper end thereof, more particularly, toward a steam discharge side, in order to achieve an increase in a steam injection pressure. This facilitates the refresh operation of clothes using the steam.
As stated above, although the refresher in accordance with the present invention has the basic effects of sterilizing and de-wrinkling clothes, it is also able to remove bad smells of the clothes when perfume is added into the water storage space of the base. Accordingly, it will be appreciated that the refresher can achieve a variety of effects in accordance with functional additives supplied thereto.

MODE FOR THE INVENTION

Now, a refresher for clothes in accordance with a further embodiment of the present invention will be explained with reference to FIGS. 11 to 21. In the present embodiment, a blowing device is included in the refresher.
As shown in FIGS. 11 to 13, a blowing device 600, may be placed in the base. In this case, it is desirable that the blowing device 600 be located out of the water storage space. The blowing device 600 includes an axial flow fan 601 to axially suck and discharge air, and a motor 602 to rotate the axial flow fan 601. Preferably, the motor 602 is mounted to eliminate a risk of short circuit due to steam. Also, it is desirable that the blowing device 600 is mounted to discharge air toward the water storage space. The blowing device 600 serves to bring about circulation of steam, and also, to apply a shock to clothes or slightly shake the clothes via collision between the steam and the clothes, thereby functioning as an assistant for a clothes refresh operation.
Referring to FIGS. 14 and 15, the lattice partition 170 is preferably provided above the water storage space and the blowing device to allow the passage of steam.
Referring to FIGS. 16 and 17, alternatively, a blowing device may be mounted to discharge air upward in an oblique direction.
In this case, the blowing device 610 includes an axial flow fan 612 to axially suck and discharge air, and a motor 612 to rotate the axial flow fan. The axial flow fan is mounted such that a rotary axis thereof has a predetermined inclination angle.
The refresher of the present embodiment, as shown in FIG. 17, acts to allow air to come into direct contact with clothes, so as to accomplish more efficient contact between the steam and the clothes.
Referring to FIGS. 18 and 19, alternatively, a blowing device 620 may include a centrifugal fan 621 designed to suck air in an axial direction and to discharge the sucked air in a radial direction.
In addition to the centrifugal fan 621 to axially suck the air and to radially discharge the sucked air, the blowing device 620 includes a motor 622 to rotate the centrifugal fan 621, and a case 623 to guide a flow path of the air discharged from the centrifugal fan 621. The case 623 is formed with a suction hole to correspond to the axial direction of the centrifugal fan 621, and a discharge hole to correspond to the radial direction of the centrifugal fan. Here, the discharge hole may be oriented to face upward or to be tilted upward.
With the above described configuration, if the blowing device starts to operate during the implementation of the refresh operation, as shown in FIG. 19, the steam generated in the steam generator is first sucked axially into the blowing device, and then, is discharged in the radial direction of the blowing device. In this case, the centrifugal fan can successfully achieve higher flow rate of air than the axial flow fan. Therefore, the centrifugal fan is suitable for use in a large capacity refresher.
Referring to FIGS. 20 and 21, alternatively, the blowing device 630 may be provided inside the cover 300. In this case, the blowing device 630 includes a centrifugal fan 631 to suck air in an axial direction and to discharge the sucked air in a radial direction.
In addition to the centrifugal fan 631 to axially suck the air and radially discharge the sucked air, the blowing device 630 includes a motor 632 to rotate the centrifugal fan 631, and a case 633 to guide a flow path of the air discharged from the centrifugal fan 631. The case 633 is formed with a suction hole to correspond to the axial direction of the centrifugal fan 631, and discharge holes to correspond to the radial direction of the centrifugal fan 631. Here, preferably, the suction hole is oriented to face downward, and the discharge holes are oriented to face opposite sides of the cover.
With this configuration, if the blowing device starts to operate during the implementation of the refresh operation, as shown in FIG. 21, the blowing device sucks air upward in the inner space of the refresher, and discharges the air toward opposite sidewalls of the cover 300. In this case, in accordance with the flow of air, the steam generated in the steam generator 200 first passes through the clothes. In succession, the steam is sucked into the blowing device 630 and then, is again discharged into the inner space of the refresher. When the circulation of steam is brought about by the circulation of air, it has the effect of preventing the steam from being concentrated on a specific portion of the clothes. Also, when the air is sucked above the clothes, the steam is able to come into contact with the clothes as soon as being evaporated, and therefore, this results in a reduction in heat loss of the steam.
Now, a refresher in accordance with another embodiment of the present invention will be explained with reference to FIGS. 22 to 28. In the present embodiment, a steam injection device is included in the refresher.
An upper steam injection device 700 for injecting steam into an upper space of the body 400 is provided between the base 100 and the cover 300. The upper steam injection device 700 is configured to inject the steam generated by the steam generator 200 into the upper space of the body 400 adjacent to the cover 300.
Here, as shown in FIGS. 22 and 25, the upper steam injection device 700 includes a steam injection pipe 701, and a steam supply pipe 702.
The steam injection pipe 701 is provided in the cover 300, and has a steam injector 611 including a plurality of holes formed at the bottom of the cover 300 adjacent to the upper space of the body 400.
The steam supply pipe 702 extends between the base 100 and the steam injection pipe 701 to communicate with the water storage space of the base 100. The steam supply pipe 702 is configured to be extendible and contractible in length.
Specifically, the steam supply pipe 702 has a telescopic structure such that the length thereof is extendible and contractible in accordance with the unfolding and folding operations of the body 400.
Preferably, the steam supply pipe 702 is detachably connected to the steam injection pipe 701.
When the steam supply pipe 702 is detachably connected to the steam injection pipe 701, more preferably, a packing is provided at a joint between the steam supply pipe 702 and the steam injection pipe 701 to seal a steam passage.
In the present embodiment, although the steam supply pipe 702 is illustrated and explained to be located in the body 400, it will be appreciated that the steam supply pipe 702 may be located at the outside of the body 400.
One end of the steam supply pipe 702 communicates with the water storage space of the base 100, and the other end of the steam supply pipe 702 communicates with the steam injection pipe 701. Accordingly, as the body 400 is folded and unfolded, the length of the steam supply pipe 702 is contractible and extendible in a telescopic manner.
Meanwhile, although not shown, the steam supply pipe 702 may have a plurality of longitudinal pleats, which are adapted to be folded and unfolded in a bellows manner, to be extendible and contractible in length.
The steam, generated by the heat radiating operation of the heater 210, rises along the steam supply pipe 702, and is injected into the upper space of the body 400 through the steam injection holes 611 of the steam injection pipe 701 that communicates with the steam supply pipe 702.

The reader 930 may be selected from among a variety of elements including a limit switch and proximity sensor.
Of course, it will be appreciated that the steam generator 200 of the refresher may be controlled to operate even when the steam is supplied from an external source through the steam supply unit 900, if necessary.
Meanwhile, when the refresher in accordance with the embodiment of the present invention is used to cooperate with a washing apparatus 10 (for example, washing machine or clothes drying machine) as shown in FIG. 37, the refresher will be operated in the following serial procedure.
In this case, assuming that the washing apparatus 10 includes a steam generator 20 that is configured to generate steam independently of the refresher, and that the steam generator 20 is connected to a steam flow pipe 30. Preferably, the steam flow pipe 20 is configured to be selectively pulled out of the washing apparatus 10.
When using the washing apparatus 10, if it is desired to perform the refresh operation of a variety of clothes received in the refresher by use of the steam generator 20 provided in the washing apparatus 10, the opening/closing door 920, which closes the pipe connection opening 910 of the refresher, is operated to open the pipe connection opening 910.
Then, the steam flow pipe 30 is connected to the opened pipe connection opening 910.
If the steam flow pipe 30 is connected, the reader 930 provided at the pipe connection opening 910 recognizes the connection of the steam flow pipe 30, and provides the recognized information to the controller 220 of the refresher, so as to prevent the operation of the steam generator 200 provided in the refresher.
It will be noted that the opening operation of the cover 300 of the refresher and the serial operation for putting clothes into the body 400 are performed in the same manner as the independent operation of the refresher.
Then, if the steam generator 20 of the washing apparatus 10 is operated, steam is generated from the steam generator 20, and is transferred into the inner space of the base 100 of the refresher through the steam flow pipe 30.
In succession, the transferred steam rises toward the inner space of the body 400 of the refresher, to be supplied to clothes received in the body 400.
As will be easily understood from the above description, when the refresher of the present invention is used to cooperate with the washing apparatus 10, the steam generator 200 may be omitted. However, in order to allow the refresher to be used independently of and to be combined with the washing apparatus 10, it is most desirable that the refresher includes the steam generator 200.
One end of the steam flow pipe 30, which is connected at the other end thereof to the steam generator 20 of the washing apparatus 10, may be connected to communicate with the cover 300 rather than the base 100.

Although not shown, preferably, at least one of a temperature sensor, humidity sensor, and water level sensor is provided at the steam generator 1170, 1211, 1212, and 1213 or in the base 100, in order to prevent the water stored in the water container from dropping below a predetermined water level.
The blowing device 640 is placed in the base 100 at the outside of the water container 1170.
Preferably, the partition 170 is provided above the water container 1170 and the blowing device 640 to allow the passage of steam.
FIG. 47 illustrates an alternative refresher which is provided with a blowing device 650 at an upper side of the water container 1170. The blowing device 650 includes an axial flow fan 651 to suck and discharge air in an axial direction, and a motor 652 to rotate the axial flow fan.
FIG. 48 illustrates another partition 1160 configured to separate the water storage space from the remaining inner space of the base 100.
Meanwhile, when the high-temperature heat generated by the electric heating coil 1212 is transferred to the heat conductive plate 1171 provided in the water container 1170, the steam generator of the above described refresher may fail to achieve efficient heat conduction if the heat conductive plate 1171 (or the bottom surface of the water container) does not come into sufficient contact with the electric heating coil 1212.
Accordingly, to solve the above problem, hereinafter, a configuration for allowing both the heat conductive plate and the electric heating coil of the steam generator to come into direct contact with each other will be explained.
FIG. 49 is a sectional view for explaining an alternative configuration of the above described steam generator. As will be appreciated from FIG. 49, the alternative steam generator basically includes a heat conductive plate 1221, an electric heating coil 1222, a power connection terminal 1224, and a controller 1223.
The heat conductive plate 1221 is provided at the inner wall surface of the water container 1170, more particularly, at the bottom side of the water container 1170 to be mounted on the base 100.

More preferably, the electric heating coil 1222 is configured to come into close contact with the lower surface of the heat conductive plate 1221.
The bottom surface of the water container 1170 is preferably made of a heat resistance material having a low heat conductivity. This is to prevent damage to peripheral circuit elements when the bottom surface of the water container 1170 is overheated.
A protrusion 1172 is formed at the water container 1170 to protrude upward by a predetermined height at a position corresponding to the center of the heat conductive plate 1221. A terminal of the electric heating coil 1222 is exposed along an inner circumference of the protrusion 1172.
The power connection terminal 1224 is received in the base 100, more particularly, in the protrusion 1172 of the water container 1170, to come into contact with the terminal of the electric heating coil 1222.
The power connection terminal 1224 serves to provide the electric heating coil 1222 with electric power.
The controller 1223 is provided in the inner space of the base 100, and is adapted to selectively supply electric power to the power connection terminal 1224.
With the above described configuration, if the water container 1170, in which water is stored, is mounted at a region where the power connection terminal 1224 is located, the electric, heating coil 1222 and the power connection terminal 1224 are brought into contact with each other, to enable the supply of electric power to the electric heating coil 1222. Then, if the controller 1223 is operated to start the refresh operation, the electric heating coil 1222 performs a heat radiating operation by use of the electric power supplied thereto.
If high-temperature heat is generated by the heat radiating operation of the electric heating coil 1222, the high-temperature heat is transferred to the heat conductive plate 1221 that comes into close contact with an upper surface of the electric heating coil 1222, thereby allowing the water stored in the water container 1170 to be heated and evaporated. With the evaporation of water, steam is able to be generated.
