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.
DISCLOSURE OF INVENTIONTechnical Problem
• An object of the present invention devised to solve the problem lies on an apparatus which enables short term storage of clothes and can perform a refresh operation for de-wrinkling and sterilizing the clothes stored.
• Another object of the present invention devised to solve the problem lies on a new refresher which can be used independently based on configuration thereof, and can achieve an improvement in installation and portability thereof.

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 toFIGS. 1 to 10.
• As shown inFIGS. 1 and 2, the refresher basically comprises abase100, asteam generator200, acover300, and abody400.
• Here, thebase100 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 base100 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 thebase100. 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 base100 be further formed with aninlet opening110 to introduce water into the water storage space.
• Preferably, theinlet opening110 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 base100 be further provided with aninlet passage120 between theinlet opening110 and the water storage space. This is for the sake of achieving the accurate introduction of water.
• Theinlet opening110 is preferably provided with an opening/closing door130, to be selectively opened and closed.
• Thesteam generator200, which is one constituent element of the refresher, serves to selectively heat and evaporate the water stored in thebase100.
• Thesteam generator200 includes a heat-radiatingheater210, and acontroller220.
• The heat-radiatingheater210 is installed such that one end thereof is located in the water storage space of thebase100 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-radiatingheater210, where the terminal is formed, be provided with a packing211 for preventing leakage of water.
• In particular, the heat-radiatingheater210 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.
• Thecontroller220 is located in an inner space of the base100 separated from the water storage space, and is adapted to control a heat-radiating operation of theheater210.
• Preferably, anoperation panel140 is provided at a front surface of thebase100 for manual control of thecontroller220. The reason why theoperation panel140 is located at the front surface of thebase100 is to keep theoperation panel140 at a fixed position regardless of folding and unfolding operations of thebody400, and also, to ensure easy manual operation of theoperation panel140 regardless of the user's height.
• In the case of the above describedsteam generator200, if the level of water, stored in the water storage space of thebase100, drops below the lowest water level, the heat-radiatingheater210 is exposed to the outside, and this may result in a risk of fire.
• For this reason, although not shown, it is desirable that thesteam generator200 or the base100 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.
• Thecover300, which is one constituent element of the refresher, serves to selectively close an upper surface of thebase100, and preferably, is configured to have a predetermined space therein.
• Aholder bar310 is provided in the space of thecover300 to hang a clothes hanger thereon. Theholder bar310 is connected at both ends thereof to two shorter side surfaces of therectangular cover300 facing each other.
• Of course, it will be appreciated that both the ends of theholder bar310 may be connected to opposite longer side surfaces of thecover300 facing each other.
• Thecover300 is preferably formed with anoutlet opening320 to discharge part of air or steam existing in the space of thecover300.
• Theoutlet opening320 may take the form of a simple opening, but may be formed to be adjustable in the degree of opening thereof.
• Thebody400, which is one constituent element of the refresher, is connected between the base100 and thecover300. Preferably, thebody400 is made of a foldable flexible material.
• In particular, thebody400 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 thebody400 is provided with a structure for selective opening of the receiving space.
• The structure for opening and closing the receiving space of thebody400 may be preferably a zipper.
• Such a structure for opening and closing the receiving space must allow a user to easily put clothes into thebody400 and take out the clothes from thebody400, and also, prevent steam present in theclosed body400 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 thebody400 is made of a flexible material, it is desirable that the refresher further comprise asupporter500 to support thebody400 when thebody400 is completely unfolded, as shown inFIGS. 3 to 6.
• Thesupporter500 is preferably connected at both ends thereof to rear surfaces of both thebase100 and thecover300 and adapted to be folded and unfolded like a link. Although not shown, it will be appreciated that thesupporter500 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, thecover300 closes the upper surface of the base100 as shown inFIGS. 1 to 3.
• In such a closed state, thebody400 is hidden inside thecover300 and the base100 while being in a folded state.
• Then, when it is intended to perform a clothes refresh operation, thecover300 is opened away from thebase100.
• In accordance with the opening operation of thecover300, thebody400 is exposed from between thecover300 and thebase100, and is gradually unfolded.
• Referring toFIGS. 4 to 6, thebody400 is shown in a completely unfolded state.
• After being completely unfolded, thebody400 is able to be continuously kept in the unfolded state by thesupporter500.
• Also, in the completely unfolded state of thebody400, the zipper is operated to open the inner surface of thebody400.
• After clothes to be refreshed are hung on hangers, and in turn, the hangers are hung on theholder bar310 inside thecover300, the zipper is again operated to close the inner space of thebody400.
• In this way, the clothes are received in thebody400.
• After that, thecontroller220 of thesteam generator200 is controlled to operate the heat-radiatingheater210.
• If theheater210 operates to radiate heat in accordance with the above described serial procedure, the water stored in thebase100 is heated and evaporated, resulting in generation of steam.
• The steam generated as stated above rises from the inner space of thebase100, to be supplied into thebody400, and consequently, to be supplied to the clothes received in thebody400.
• 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 thebody400 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 thebody400 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 theoutlet opening320 formed at thecover300 be opened if the refresh operation is performed.
• In the above described refresher, meanwhile, the water storage space of thebase100 for receiving the water required to generate steam is configured to communicate with the inner space of thebody400, 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 theholder bar310.
• Furthermore, in a state wherein thecover300 closes the base100 as shown inFIG. 2, thebody400 may be wet by the water stored in thebase100.
• 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 apartition170 inside the base100 as shown inFIGS. 7 and 8.
• Preferably, thepartition170 is configured to separate the water storage space of the base100 from a space above the water storage space while allowing the steam generated by thesteam generator200 to be efficiently supplied into the inner space of thebody400 where the clothes are received.
• For this, thepartition170 may take the form of a lattice grill or mesh.
• When thepartition170 takes the form of the lattice grill or mesh, the steam is able to be distributed throughout thepartition170, and therefore, is able to be uniformly supplied into the overall inner space of thebody400.
• More preferably, thepartition170 may be detachably coupled to an inner wall surface of thebase100, for the sake of cleaning of the inner space of thebase100.
• With the use of thepartition170, even in a state wherein thecover300 closes thebase100, thebody400 is placed on thepartition170, thereby being kept in a stably folded state without a risk of being wet by the water stored in thebase100.
• Also, in a state wherein thecover300 opens thebase100, more particularly, in a state wherein thebody400 is unfolded for the use of the refresher as shown inFIG. 8, thepartition170 prevents the lower end of the clothes from reaching the water stored in thebase100.
• Referring toFIG. 9, ablowing device630 may be mounted at thecover300, to facilitate efficient circulation of the steam in the inner space of thebody400.
• Theblowing device630 is able to discharge air inside thebody400 to the outside, and to achieve efficient circulation of steam and air.
• The reason why theblowing device630 is provided at thecover300 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 toFIG. 10, apartition821 having a plurality ofinjection nozzles822 for the injection of steam may be provided.
• The injection nozzles822 are configured to protrude upward from thepartition821 by a predetermined height, and each has a hollow tubular form.
• Preferably, theinjection nozzle822, 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 toFIGS. 11 to 21. In the present embodiment, a blowing device is included in the refresher.
• As shown inFIGS. 11 to 13, ablowing device600, may be placed in the base. In this case, it is desirable that theblowing device600 be located out of the water storage space. Theblowing device600 includes anaxial flow fan601 to axially suck and discharge air, and amotor602 to rotate theaxial flow fan601. Preferably, themotor602 is mounted to eliminate a risk of short circuit due to steam. Also, it is desirable that theblowing device600 is mounted to discharge air toward the water storage space. Theblowing device600 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 toFIGS. 14 and 15, thelattice partition170 is preferably provided above the water storage space and the blowing device to allow the passage of steam.
• Referring toFIGS. 16 and 17, alternatively, a blowing device may be mounted to discharge air upward in an oblique direction.
• In this case, theblowing device610 includes anaxial flow fan612 to axially suck and discharge air, and amotor612 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 inFIG. 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 toFIGS. 18 and 19, alternatively, ablowing device620 may include acentrifugal fan621 designed to suck air in an axial direction and to discharge the sucked air in a radial direction.
• In addition to thecentrifugal fan621 to axially suck the air and to radially discharge the sucked air, theblowing device620 includes amotor622 to rotate thecentrifugal fan621, and acase623 to guide a flow path of the air discharged from thecentrifugal fan621. Thecase623 is formed with a suction hole to correspond to the axial direction of thecentrifugal fan621, 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 inFIG. 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 toFIGS. 20 and 21, alternatively, theblowing device630 may be provided inside thecover300. In this case, theblowing device630 includes acentrifugal fan631 to suck air in an axial direction and to discharge the sucked air in a radial direction.
• In addition to thecentrifugal fan631 to axially suck the air and radially discharge the sucked air, theblowing device630 includes amotor632 to rotate thecentrifugal fan631, and acase633 to guide a flow path of the air discharged from thecentrifugal fan631. Thecase633 is formed with a suction hole to correspond to the axial direction of thecentrifugal fan631, and discharge holes to correspond to the radial direction of thecentrifugal fan631. 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 inFIG. 21, the blowing device sucks air upward in the inner space of the refresher, and discharges the air toward opposite sidewalls of thecover300. In this case, in accordance with the flow of air, the steam generated in thesteam generator200 first passes through the clothes. In succession, the steam is sucked into theblowing device630 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 toFIGS. 22 to 28. In the present embodiment, a steam injection device is included in the refresher.
• An uppersteam injection device700 for injecting steam into an upper space of thebody400 is provided between the base100 and thecover300. The uppersteam injection device700 is configured to inject the steam generated by thesteam generator200 into the upper space of thebody400 adjacent to thecover300.
• Here, as shown inFIGS. 22 and 25, the uppersteam injection device700 includes asteam injection pipe701, and asteam supply pipe702.
• Thesteam injection pipe701 is provided in thecover300, and has asteam injector611 including a plurality of holes formed at the bottom of thecover300 adjacent to the upper space of thebody400.
• Thesteam supply pipe702 extends between the base100 and thesteam injection pipe701 to communicate with the water storage space of thebase100. Thesteam supply pipe702 is configured to be extendible and contractible in length.
• Specifically, thesteam supply pipe702 has a telescopic structure such that the length thereof is extendible and contractible in accordance with the unfolding and folding operations of thebody400.
• Preferably, thesteam supply pipe702 is detachably connected to thesteam injection pipe701.
• When thesteam supply pipe702 is detachably connected to thesteam injection pipe701, more preferably, a packing is provided at a joint between thesteam supply pipe702 and thesteam injection pipe701 to seal a steam passage.
• In the present embodiment, although thesteam supply pipe702 is illustrated and explained to be located in thebody400, it will be appreciated that thesteam supply pipe702 may be located at the outside of thebody400.
• One end of thesteam supply pipe702 communicates with the water storage space of thebase100, and the other end of thesteam supply pipe702 communicates with thesteam injection pipe701. Accordingly, as thebody400 is folded and unfolded, the length of thesteam supply pipe702 is contractible and extendible in a telescopic manner.
• Meanwhile, although not shown, thesteam supply pipe702 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 theheater210, rises along thesteam supply pipe702, and is injected into the upper space of thebody400 through the steam injection holes611 of thesteam injection pipe701 that communicates with thesteam supply pipe702.
• FIG. 27 illustrates another upper steam injection device.
• Here, asteam injection pipe711 is integrally formed in thecover300 to have a pre-determined space therein. Thesteam injection pipe711 has asteam injector713 formed at a bottom surface of thecover300.
• Thesteam injector713 includes an elongated slot extending in a longitudinal direction of thecover300, more particularly, in a leftward and rightward direction thereof.
• Although not shown, it will be appreciated that the steam injector may take the form of a plurality of holes, or may take the form of a plurality of nozzles.
• In the same manner as the above describedsteam supply pipe702, preferably, asteam supply pipe712 is extendible and contractible in length, and is detachably connected to thesteam injection pipe711.
• FIG. 28 illustrates yet another upper steam injection device.
