SHOES CARE DEVICE

TECHNICAL FIELD

The present invention relates to a shoes care device, and more particularly, to a shoes care device which treats shoes by air circulation.

BACKGROUND

Shoes may get wet by a wearer's sweat, external contaminants, or rain or snow. Wearing such shoes may make the wearer uncomfortable, and in this condition, germs may also breed or the shoes may stink.

Accordingly, there is an increasing interest in a shoes care device, which removes germs and odors by performing a predetermined treatment on the shoes so that a user can comfortably wear the shoes all the time.

For the shoes care device, Korean Patent No. 10-1037245 (hereinafter, referred to as “Prior Art Document 1”), entitled, “Apparatus for sterilization disposal of shoes”, includes a main body, an ultraviolet emission module, and a deodorization module.

According to Prior Art Document 1 above, the shoes are disposed in a sterilization chamber of the main body, and the ultraviolet emission module is driven to remove germs and odors of the shoes. Furthermore, the air in the sterilization chamber is sucked into a ventilation pipe and discharged to the outside of the main body through an exhaust port through the deodorization module.

Here, the deodorization module includes a deodorization column made up of materials such as zeolite, activated carbon, and charcoal, and removes contaminants from the air discharged from the inside of the main body to the outside by the deodorization column.

According to Prior Art Document 1 above, the air from which moisture has been removed by a deodorization module including zeolite and activated carbon can be discharged to the outside of the apparatus for sterilization of shoes.

However, in Prior Art Document 1 above, since the air is discharged to the outside of the apparatus for sterilization of shoes, the air that has not sufficiently removed moisture or odors may be discharged to the outside of the apparatus for sterilization of shoes, and such air may be discharged to the inside where the wearer resides.

In addition, Korean Patent Unexamined Publication No. 10-2000-0009653 (hereinafter referred to as “Prior Art Document 2”), entitled, “The shoes cabinet for sanitation”, discloses a shoe closet that includes a main body, a far infrared radiation part, a circulation fan, an air circulation passage, and a sanitary filter portion.

According to Prior Art Document 2 above, while storing shoes in the shoe closet, hygiene treatments such as dehumidification, sterilization, and deodorization can be performed on the shoes by far-infrared rays and a filter during the storing of the shoes.

Here, since the sanitary filter portion is filled with excellent adsorptive materials such as charcoal, it can serve to adsorb moisture in the process of ventilating air and filter bacteria, as well as to capture malodorous substances.

According to Prior Art Document 2 above, the air is circulated by a circulating fan in a shoe closet, and the sanitary filter portion is disposed on a circulation path of the air to remove germs and odors in the air.

However, since Prior Art Document 2 above does not consider a technology to prevent the reduction of the performance of the sanitary filter portion configured to remove moisture or odors, a user may not be satisfied because the shoes are not properly treated at the time of using a shoes care device.

As described above, for the shoes care device that removes germs or odors by treating the shoes in a predetermined manner, a task that has to be solved to ensure proper performance for shoes treatment while preventing the air used for dehumidification and deodorization from being exposed to the user is present in in the process of treating the shoes.

However, there is a limitation in that the conventional shoes care device cannot properly solve such a task.

In addition, when designing and manufacturing devices including a dehumidifier such as zeolite, it is necessary to consider how the dehumidification efficiency of a dehumidifying material can be further improved, whether the dehumidifying material can be effectively regenerated, whether water vapor generated during the use of the shoes care device and the regeneration of the dehumidifying material can be effectively removed or managed, whether moisture is left in an unintended area during use of the shoes care device and the regeneration of the dehumidifying, whether components are properly disposed in a limited space, and whether the devices provides excellent use convenience. There is a need to develop a shoes care device that takes these matters into consideration.

In addition, the reduction of manufacturing costs, the convenience of manufacturing and assembling each component, and the convenience of maintenance needs to be considered in the development of the shoes care device.

To this end, the heating part 320 is disposed inside the module housing 200 adjacent to the dehumidifying part 330. Specifically, the heating part 320 is disposed inside the module housing 200 adjacent to the dehumidifying part 330 based on a movement path of the air inside the module housing 200.

In the module housing 200, the dehumidification by the dehumidifying material 331 or the regeneration of the dehumidifying material 331 may be achieved by selectively heating the heating part 320.

The heating part 320 may be fixedly coupled to the module housing 200 in the module housing 200.

The heating part 320 may be made up of various devices and structures within a range capable of heating the air inside the module housing 200 or supplying heat to the dehumidifying part 330.

The heating part 320 may be formed of an electric heater 321. In one embodiment of the present invention, the heating part 320 may include the heater 321. The heater 321 includes a heating element, and may be configured to supply heat to the periphery while the heating element generates heat by supplied electric energy. The heater 321 may include a nichrome wire as the heating element.

The heater 321 of the heating part 320 may be formed in a ring shape, and the air may move by penetrating the center and surroundings of the ring-shaped heater 321 and be simultaneously heated. The heater 321 of the heating part 320 may be repeatedly formed in a second module chamber 213 along the movement direction of air.

The heater 321 of the heating part 320 may be formed in a circular ring shape or a rectangular ring shape.

The heating part 320 may include a heater flange 322 to which the heater 321 is fixed.

The heater flange 322 may be formed in the form of a metallic plate.

The heater flange 322 may be formed of a combination of flat plates in the second module chamber 213 along the movement direction of air. The heater flange 322 has a cross section that may be formed of a plate shape or a combination of plates in the second module chamber 213 along the movement direction of air (the second direction (Y direction)).

The heater flange 322 may include an outer flange 322a and an inner flange 322b.

The outer flange 322a may be formed in a tubular shape along the second direction (Y direction). An interior of the outer flange 322a is provided with a space to move air along the movement direction of air (a direction parallel to the second direction (Y direction)) in the second module chamber 213.

The inner flange 322b is fixed to the interior of the outer flange 322a. The inner flange 322b may include two or more plates crossing each other, and the heater 321 of the heating part 320 may be fixed to the inner flange 322b.

The heater flange 322 may be formed in various forms that fix the heater 321 of the heating part 320 and do not interfere with a flow of air moving through the second module chamber 213.

In one embodiment of the present invention, the blowing part 310, the heating part 320, the dehumidifying part 330, and the module housing 200 may form one set.

The set may be provided in a plural form. The shoes care device 1 according to one embodiment may be provided with two sets.

Such a set may be provided in each of the first management device 2a and the second management device 2b.

Such a set may form a drying module DM in the shoes care device 1 according to one embodiment of the present invention.

That is, in one embodiment of the present invention, the drying module DM may include the module housing 200, the blowing part 310, the heating part 320, and the dehumidifying part 330. Furthermore, the drying module DM is provided in each of the first management device 2a and the second management device 2b.

In the shoes care device 1 according to one embodiment of the present invention, a plurality of drying modules DM may be provided.

In the shoes care device 1 according to one embodiment of the present invention, a pair of drying modules DM may be provided. When the shoes care device 1 is provided with the pair of drying modules DM, one of the drying modules DM may form a ‘drying module A (DM1)’ as a drying module of the first management device 2a, and the other may form a ‘drying module B (DM2)’ as a drying module of the second management device 2b.

The ‘drying module’ described in one embodiment of the present invention may be understood to refer to each of the ‘drying module A’ and the ‘drying module B’ except as otherwise particularly limited.

In the shoes care device 1 according to one embodiment of the present invention, the drying module A (DM1) and the drying module B (DM2) may operate in different modes. When the drying module A (DM1) operates in a moisture absorption mode, the drying module B (DM2) may operate in a regeneration mode. Conversely, when the drying module A (DM1) operates in the regeneration mode, the drying module B (DM2) may operate in the moisture absorption mode.

The ‘moisture absorption mode’ described in the present invention means a case in which the dehumidifying part 330 adsorbs moisture in the air, and the ‘regeneration mode’ means a case in which the moisture adsorbed to the dehumidifying part 330 is separated by heating the dehumidifying part 330.

Naturally, both the drying module A (DM1) and the drying module B (DM2) may operate in the moisture absorption mode or may operate in the regeneration mode.

The module housing 200 may be fixedly coupled to a lower side of the inner cabinet 100. The module housing 200 may be detachably coupled to a lower side of the inner cabinet 100.

The module housing 200 includes the module chamber 210 that is a space having other components accommodated inside. That is, the module chamber 210 is a space inside the module housing 200 distinguished from an external space of the module housing 200. As described above, the module housing 200 forms part of the connection path F10, and accordingly, the module chamber 210 is configured to communicate with a space outside the module housing 200. The module chamber 210 communicates with the accommodation space 101 of the inner cabinet 100.

The module housing 200 may include a module case 201 and a module cover 202.

The module case 201 and the module cover 202 may be formed by injection molding, respectively, and may be assembled with each other after manufacturing to form the module housing 200.

The module case 201 is formed in the form of a container that is concave substantially downwards, and forms the module chamber 210 of the module housing 200.

The module case 201 may be configured in the form of a container opened upwards, and includes a module opening 201a.

In a plan view, an area of the module opening 201a may be larger than or equal to an area of the module chamber 210.

The module chamber 210 may include a first module chamber 212, a second module chamber 213, and a third module chamber 214. The module chamber 210 may include a suction module chamber 211.

In order to distinguish between the suction module chamber 211, the first module chamber 212, the second module chamber 213, and the third module chamber 214, a module partition wall 220 may be formed inside the module housing 200. Furthermore, the module partition wall 220 guides the movement of air so that air moves in a predetermined direction inside the module housing 200.

The suction module chamber 211 is a first space where air is introduced into the module housing 200.

The first module chamber 212 is a space in which the blowing part 310 is accommodated, the second module chamber 213 is a space in which the heating part 320 is accommodated, and the third module chamber 214 is a space in which the dehumidifying part 330 is accommodated.

In one embodiment of the present invention, the suction module chamber 211, the first module chamber 212, the second module chamber 213, and the third module chamber 214 may be formed at different positions in a plan view.

In addition, the air of the module chamber 210 may be configured to move through the suction module chamber 211, the first module chamber 212, the second module chamber 213, and the third module chamber 214 sequentially. That is, when the blowing part 310 is driven, air moves sequentially through the suction module chamber 211, the first module chamber 212, the second module chamber 213, and the third module chamber 214 inside the module housing 200.

The module case 201 may include a dry air outlet 231 and a wet air outlet 232.

The dry air outlet 231 may be formed in a hole shape opened to allow air in the third module chamber 214 to flow out. The dry air outlet 231 is formed adjacent to the third module chamber 214. The dry air outlet 231 may be formed on one edge of the module case 201. Furthermore, the dry air outlet 231 may be connected to the accommodation space 101 through the dry air duct 370 and the nozzle duct 810.

The wet air outlet 232 may be formed in a hole shape opened to allow the air in the third module chamber 214 to flow out. The wet air outlet 232 is formed adjacent to the third module chamber 214. The wet air outlet 232 may be formed on a frame on one side of the module case 201. Furthermore, the wet air outlet 232 may be connected to the condenser 400.

The dry air outlet 231 and the wet air outlet 232 may be formed adjacent to each other. The dry air outlet 231 and the wet air outlet 232 may be formed adjacent to any one vertex part of the module housing 200.

The suction module chamber 211 is formed adjacent to the first module chamber 212, and a bottom surface of the suction module chamber 211 may be inclined downwardly toward the first module chamber 212. Accordingly, air introduced into the suction module chamber 211 may naturally move toward the first module chamber 212 by hitting the bottom surface of the suction module chamber 211 forming an inclined surface, and a condensed water introduced into the suction module chamber 211 may move along the bottom surface of the suction module chamber 211 forming the inclined surface, and may move to the first module chamber 212.

The blowing part 310 may be assembled to the module housing 200 while being spaced apart from a bottom surface of the first module chamber 212. Furthermore, in this case, the blowing part 310 may be configured such that air may be introduced from a lower side of the first module chamber 212 to an interior of the blowing part 310 inside the first module chamber 212.

The module case 201 may include a first condensed water discharge hole 233.

The first condensed water discharge hole 233 is formed in a hole shape penetrating the module case 201. The first condensed water discharge hole 233 is formed on an edge of the module case 201 adjacent to a condenser 400 and formed to be equal to or lower than the bottom surface of the first module chamber 212, and communicates with the condenser 400. Among the bottom surfaces of the first module chamber 212, the first condensed water discharge hole 233 may form the lowest part, or the bottom surface of the first module chamber 212 may be formed such that a height thereof is lowered toward or at least equal to the first condensed water discharge hole 233.

As such, the first condensed water discharge hole 233 may be lower than the bottom surface of the first module chamber 212, and accordingly, the condensed water introduced into the first condensed water discharge hole 232 may move toward the first condensed water discharge hole 233 and flow into the condenser 400 through the first condensed water discharge hole 233.

Meanwhile, since the first condensed water discharge hole 233 is a hole in which the module housing 200 and the condenser 400 communicate with each other, the air inside the condenser 400 may flow into the module housing 200 through the first condensed water discharge hole 233. The air introduced into the module housing 200 through the first condensed water discharge hole 233 from an interior of the condenser 400 may move along the first module chamber 212, the second module chamber 213, and the third module chamber 214 by an operation of the blowing part 310 and may be introduced again into the condenser 400 and condensed.

The shoes care device 1 according to one embodiment of the present invention includes the condenser 400 coupled to an outer surface of the inner cabinet 100 and forming a regeneration path F20. In a plan view, the first module chamber 212 may be provided between the second module chamber 213 and the condenser 400. Since the first module chamber 212 is disposed between the second module chamber 213 and the condenser 400, a direct heat exchange between the condenser 400 and the heating part 320 is blocked, and the heat may be prevented from being transferred to the condenser 400 when the heating part 320 is heated inside the second module chamber 213.

Accordingly, when the dehumidifying part 330 is regenerated, condensation depending on heating of air by the heater 321 of the heating part 320 and cooling of air inside the condenser 400 may be effective performed.

The dehumidifying part 330 may be coupled to the module housing 200 while being spaced apart from a bottom surface of the third module chamber 214. Furthermore, in this case, the air inside the third module chamber 214 may move downwards through the dehumidifying part 330 from an upper side of the third module chamber 214.

The module case 201 may include a second condensed water discharge hole 234.

The second condensed water discharge hole 234 is formed in a hole shape penetrating the module case 201. The second condensed water discharge hole 234 is formed on the edge of the module case 201 adjacent to the condenser 400 and formed to be equal to or lower than the bottom surface of the third module chamber 214, and communicates with the condenser 400. Among the bottom surfaces of the third module chamber 214, the second condensed water discharge hole 234 may form the lowest part, or the bottom surface of the third module chamber 214 may be formed such that a height thereof is lowered toward or at least equal to the second condensed water discharge hole 234.

The second condensed water discharge hole 234 may be formed adjacent to the wet air outlet 232.

In this way, the second condensed water discharge hole 234 may be lower than the bottom surface of the third module chamber 214, and accordingly, condensed water introduced into the third module chamber 214 may move toward the second condensed water discharge hole 234, and may flow into the condenser 400 through the second condensed water discharge hole 234.

Meanwhile, since the second condensed water discharge hole 234 is a hole in which the module housing 200 and the condenser 400 communicate with each other, the air inside the condenser 400 may flow into the module housing 200 through the second condensed water discharge hole 234. In this way, the air introduced from the interior of the condenser 400 into the module housing 200 through the second condensed water discharge hole 234 moves directly to the wet air outlet 232 by the driving of the blowing part 310, and may be introduced again into the condenser 400 and condensed.

The module housing 200 may include the module cover 202.

The module cover 202 is coupled to the module case 201 while shielding the module opening 201a from an upper side of the module case 201. The module cover 202 may be detachably coupled to the module case 201. A plurality of locking projections 292 may protrude from one of the module cover 202 and the module case 201, and a plurality of locking grooves 291 into which the locking projections 292 are inserted and locked may be formed on the other. The locking projections 292 and locking grooves 291 are provided in a plural form, respectively, and may be spaced apart along an edge of the module housing 200 and repeatedly formed.

With the blowing part 310, the heating part 320, and the dehumidifying part 330 accommodated in the module case 201, the module cover 202 may shield the blowing part 310, the heating part 320, and the dehumidifying part 330 and may be coupled to the module case 201.

The shoes care device according to one embodiment of the present invention may be formed in a structure in which the dehumidifying part 330 may be detachable from the module housing 200. The structure of the shoes care device provides an advantage in maintaining and managing the dehumidifying part 330 and the shoes care device 1 on the whole.

On the other hand, the dehumidifying part 330 may be repeatedly used by regeneration, but with the repeated use, the dehumidifying part 330 needs to be replaced.

Considering these descriptions, the shoes care device 1 according to one specific embodiment of the present invention may be configured to separate and replace the dehumidifying part 330.

In one embodiment of the present invention, the module cover 202 of the module housing 200 may form a bottom surface of the inner cabinet 100.

The module cover 202 may form a boundary surface between the inner cabinet 100 and the module housing 200. The module cover 202 may be formed in a substantially rectangular shape.

The module cover 202 may be configured in substantially parallel with the horizontal direction.

Alternatively, the module cover 202 may be inclined to any one side. In one embodiment, an upper surface of the module cover 202 may be inclined downwardly toward the first direction (X direction) (a front side of the shoes care device 1).

In one embodiment of the present invention, the main shelf 40 is mounted in close contact with an upper side surface of the module cover 202, and the main shelf 40 mounted on the upper side surface of the module cover 202 is also configured to be inclined when the upper side surface of the module cover 202 is inclined. In this case, since an upper surface of the main shelf 40 is inclined, water (e.g., condensed water) placed on the upper surface of the main shelf 40 may flow along an inclined direction.

The shoes care device 1 may include a dehumidifying material cover 241.

The dehumidifying material cover 241 forms part of the module cover 202 that is the bottom of the inner cabinet 100. Furthermore, the dehumidifying material cover 241 may be detached from the module cover 202 of the inner cabinet 100 or may be hinge-coupled to the module cover 202.

In the module cover 202, a dehumidifying material exit 240 which is an opening of a shape and a size corresponding to the dehumidifying material cover 241 may be formed. The dehumidifying material cover 241 may be configured to open and close the dehumidifying material exit 240. The dehumidifying material cover 241 may be tightly coupled to the dehumidifying material exit 240. At least a part of the dehumidifying material cover 241 may be separated from the module cover 202. In one embodiment, the dehumidifying material exit 240 of the module cover 202 may be opened while completely separating the dehumidifying material cover 241 from the module cover 202, and in another embodiment, the dehumidifying material cover 241 of the module cover 202 may be opened while rotating the dehumidifying material cover 241 around a hinge axis. The dehumidifying part 330 may be introduced into or withdrawn from the module housing 200 through the dehumidifying material exit 240.

The dehumidifying material exit 240 and the dehumidifying material cover 241 may be formed in a position corresponding to the third module chamber 214 in a plan view. That is, the dehumidifying material exit 240 and the dehumidifying material cover 241 may be formed directly above the third module chamber 214. The shoes care device 1 according to one embodiment of the present invention may be configured such that the first module chamber 212 and the second module chamber 213 are not exposed in a plan view in a state where the dehumidifier cover 241 is opened.

When the dehumidifying material cover 241 is opened in the module cover 202, the third module chamber 214 disposed on a lower part of the module cover 202 is exposed through the dehumidifying material exit 240 of the module cover 202, and the dehumidifying part 330 may be settled inside the module case 201, or may be immediately withdrawn and separated from the module case 201.

The sizes and shapes of the dehumidifying material cover 241 and the dehumidifying material exit 240 are variously provided within the range capable of withdrawing or inserting the dehumidifying part 330.

The dehumidifying material cover 241 may be formed in a rectangular plate shape.

The length of the dehumidifying material cover 241 in the first direction (X direction) may be equal to or longer than the length of the dehumidifying part 330, and the length of the dehumidifying material cover 241 in the second direction (Y direction) may be equal to or longer than the length of the dehumidifying part 330.

As described above, in the shoes care device 1 according to one embodiment of the present invention, the heating part 320 and the dehumidifying part 330 are formed at different positions in a top plane view, and when the dehumidifying material cover 241 is opened on the module cover 202 that forms the bottom surface of the inner cabinet 100, the dehumidifying part 330 disposed directly below the dehumidifying material cover 241 may be withdrawn from the module housing 200, and the dehumidifying part 330 may be easily replaced by the user.

In addition, since only the third module chamber 214 is exposed in a state in which the dehumidifier cover 241 is opened, and the first module chamber 212 and the second module chamber 213 are not exposed, the blowing part 310 accommodated in the first module chamber 212 and the heating part 320 accommodated in the second module chamber 213 are not exposed. That is, since the blowing part 310 and the heating part 320 are not directly exposed to the user, safety accidents due to an unintended operation of the blowing part 310 and/or the heating part 320 can be prevented.

The dehumidifying material cover 241 may be configured to separately shield the dehumidifying part 330. A space between the dehumidifying material cover 241 and the dehumidifying part 330 may form a part of the connection path F10.

As described above, the outlet 203 forms an inlet through which the air inside the inner cabinet 100 is sucked into the module housing 200. The outlet 203 may form a start part of the connection path F10. The outlet 203 may be formed in the shape of a hole vertically penetrated from the bottom surface (the upper surface of the module cover 202) of the inner cabinet 100.

A network such as a grid shape, a mesh shape, etc., may be formed on the outlet 203.

The outlet 203 may be formed parallel to the second direction (Y direction). That is, the outlet 203 may be formed in a long hole shape in the module cover 202 along the second direction (Y direction).

The outlet 203 may be formed on an edge of the module cover 202. The outlet 203 may be formed on the edge of the module cover 202 along the second direction (Y direction).

The outlet 203 may be formed on a front part or a rear part of the module cover 202 based on the first direction (X direction).

The outlet 203 may be disposed relatively close to the door 30 in the module cover 202. That is, the outlet 203 may be disposed relatively in the front of the module cover 202.

The upper surface of the module cover 202 may be inclined downwardly toward the outlet 203. That is, a part of the module cover 202 where the outlet 203 is formed may be configured to be the lowest. Accordingly, when water is present on the module cover 202 or the main shelf 40, such water may flow along the surface of the module cover 202 by gravity and flow into the inlet 203.

In the shoes care device 1 according to one embodiment of the present invention, the module chamber 210 is provided inside the module housing 200, and the module chamber 210 includes a first module chamber 212, a second module chamber 213, and the third module chamber 214. The first module chamber 212, the second module chamber 213, and the third module chamber 214 may be formed at different positions in a plan view. That is, the blowing part 310, the heating part 320, and the dehumidifying part 330 may be disposed at different positions in the module housing 200. According to one embodiment of the present invention, the blowing part 310, the heating part 320, and the dehumidifying part 330, which are main means for drying the air inside the inner cabinet 100 and main means for regenerating the dehumidifying part 330, are disposed together in the module chamber 210 of the module housing 200. Accordingly, the blowing part 310, the heating part 320, and the dehumidifying part 330 are disposed at positions considerably close to each other.

In one embodiment of the present invention, the module case 201 of the module housing 200 may be integrally formed by injection molding. In this case, the bottom parts of the module housing 200 may be integrally formed, the bottom parts may not be assembled with each other, and no gaps may be formed in the bottom parts.

In the arrangement explained above, the condensed water can be effectively prevented from leaking from the module housing 200. In addition, a vertical height of the module housing 200 can be minimized.

When moisture remains at an unintended part inside the shoes care device 1, such moisture may reproduce bacteria or cause odors. This is why there is need for countermeasures to solve the problems, and the shoes care device 1 according to one embodiment of the present invention can effectively prevent water from leaking in consideration of such problems.

In the shoes care device 1 according to one embodiment of the present invention, the air in the module chamber 210 may sequentially move the first module chamber 212, the second module chamber 213, and the third module chamber 214. Accordingly, since the third module chamber 214 and a drying flow path F10b may be connected in the shortest distance, which provides excellent drying efficiency by the dehumidifying part 330, and air heated by the heating part 320 moves directly to the dehumidifying part 330 to form the shoes care device 1 with excellent regeneration efficiency.

In the shoes care device 1 according to one embodiment of the present invention, the module housing 200 includes the suction module chamber 211, and the bottom surface of the suction module chamber 211 may be inclined downwardly toward the first module chamber 212. Accordingly, the air introduced through the outlet 203 moves naturally to the first module chamber 212 by hitting the bottom surface of the suction module chamber 211, and the condensed water introduced into the outlet 203 moves to the first module chamber 212 such that the condensed water can be easily drained.

The shoes care device 1 according to one embodiment of the present invention may include the condenser 400, and the module case 201 may include the first condensed water discharge hole 233. In addition, the module case 201 may include the second condensed water discharge hole 234. Accordingly, the dehumidifying part 330 may be effectively regenerated, and condensed water inside the module housing 200 may be easily discharged to the condenser 400.

In the shoes care device 1 according to one embodiment of the present invention, steam generated by the steam generator 700 is supplied to the accommodation space 101 of the inner cabinet 100, and to this end, the shoes care device 1 includes a steam inlet 204.

The steam inlet 204 forms an inlet through which steam is supplied to the accommodation space 101 of the inner cabinet 100.

In the shoes care device according to one embodiment of the present invention, the steam inlet 204 is formed in the module housing 200.

The steam inlet 204 may be formed in a rear part of the module housing 200 based on the first direction (X direction). The steam inlet 204 may be formed to vertically penetrate the module housing 200. The steam inlet 204 may be formed to vertically penetrate the module case 201 and the module cover 202. The steam inlet 204 may be formed in the center in a right-left direction at the rear part of the module housing 200.

The steam inlet 204 may be formed on a rear edge of the module housing 200, and may be formed directly behind a position where the third module chamber 214 is formed. The third module chamber 214 and the steam inlet 204 are shielded from each other.

In the module housing 200, the module cover 202 forms the bottom surface of the accommodation space 101, and when the module housing 200 is coupled to the inner cabinet 100, the steam inlet 204 is formed behind the bottom of the inner cabinet 100.

The steam generator 700 and the steam valve 710 are disposed in a lower part, the distance from the steam generator 710 to the steam inlet 204 can be reduced by forming the module housing 200, and the steam inlet 204 in a rear part of the module housing 200, and an increase in the load required for the supply of steam can be prevented. Accordingly, steam may be smoothly supplied from the steam generator 700 to the steam inlet 204.

FIG. 11 is a diagram illustrating a connection relationship between components and a flow of fluid in the shoes care device 1 according to one embodiment of the present invention.

The connection path F10 forms a movement path of air connected from the outlet 203 to the nozzle 820. That is, the outlet 203 may form an inlet of the connection path F10, and the nozzle 820 may form an outlet of the connection path F10.

The outlet 203 may be coupled to communicate with the inner cabinet 100, and the nozzle 820 may be provided inside the inner cabinet 100. Except the outlet 203 and the nozzle 820, one part of the connection path F10 may be provided inside the inner cabinet 100, and the other part may be provided outside the inner cabinet 100.

The air inside the inner cabinet 100 moves to the connection path F10 through the outlet 203, and the air passing through the connection path F10 moves back into the inner cabinet 100 through the nozzle 820. As such air flow is repeated, the air circulation is performed in the shoes care device 1.

In the nozzle 820, a hole through which air is discharged is formed in the accommodation space 101 of the inner cabinet 100, and the nozzle 820 may form a last part of the connection path F10.

In the shoes care device 1 according to one embodiment of the present invention, since the nozzle 820 is configured to be movable to various positions inside the inner cabinet 100, the shoes may be managed in various positions.

As described above, the dehumidifying part 330 is disposed in the connection path F10. The air moving through the connection path F10 passes through the dehumidifying part 330, and the dehumidifying part 330 absorbs moisture from the air moving through the connection path F10 such that the air from which moisture has been removed may be supplied into the inner cabinet 100.

The connection path F10 may be divided into a conversion flow path F10a and a drying flow path F10b. The conversion flow path F10a and the drying flow path F10b form a movement path of air sequentially connected to each other. The air in the connection path F10 may sequentially move through the conversion flow path F10a and the drying flow path F10b.

The conversion flow path F10a forms an upstream section of the connection path F10, which is connected to the outlet 203. The conversion flow path F10a may be a section in which the blowing part 310, the heating part 320, and the dehumidifying part 330 are disposed. The conversion flow path F10a may be formed by the module housing 200, and the module chamber 210 inside the module housing 200 may form the conversion flow path F10a.

The conversion flow path F10a may be a section in which humid air moves and dries. The conversion flow path F10a may be a section in which air is dehumidified by the dehumidifying part 330.

Meanwhile, the conversion flow path F10a may be a section in which the dehumidifying part 330 (the dehumidifying material 331) are regenerated.

The drying flow path F10b forms a downstream section of the connection path F10, which connects the conversion flow path F10a to the nozzle 820. A flow path formed by the drying air duct 370, the nozzle duct 810, and the nozzle 820 may form the drying flow path F10b.

The drying passage F10b may be a section in which dry air with moisture removed therefrom moves.

When the drying module DM operates in the moisture absorption mode, the drying flow path F10b communicates with the conversion flow path F10a, and when the drying module DM operates in the regeneration mode, the drying flow path F10b and the conversion flow path F10a may not communicate with each other such that the drying flow path F10b and the conversion flow path F10a block each other.

Accordingly, when air is dehumidified by the dehumidifying part 330 in the conversion flow path F10a, the dried air moves through the drying flow path F10b.

The dry air duct 370 may be fixedly coupled to an outer wall surface of the inner cabinet 100, and the nozzle duct 810 may be provided inside the inner cabinet 100.

As the dry air duct 370 is tightly coupled to an inner rear plate 110 of the inner cabinet 100, a flow path may be formed between the dry air duct 370 and the inner cabinet 100 (the inner rear plate 110), and such a flow path may form a part of the drying flow path F10b. A lower part of the dry air duct 370 communicates with the dry air outlet 231 of the module housing 200, an upper part thereof communicates with the nozzle duct 810, which connect the interior of the module housing 200 and the interior of the nozzle duct 810 for mutual communication.

As described above, after humid air in the accommodation space 101 of the inner cabinet 100 flows into the conversion flow path F10a, the air is dehumidified by the dehumidifying part 330 and converted into dry air, and the dry air can be resupplied to the accommodation space 101 of the inner cabinet 100 through the drying flow path F10b.

The regeneration path F20 forms a movement path of a fluid.

The regeneration path F20 forms a passage through which air and/or condensed water inside the shoes care device moves.

The regeneration path F20 forms a path through which air and/or condensed water passing through the dehumidifying part 330 moves when the dehumidifying material 331 is regenerated. The regeneration path F20 may be entirely or partially formed of a pipe, a hose, a tube, a duct, a housing, or a combination thereof.

Moisture generated during the regeneration process of the dehumidifying material 331 needs to be discharged through a separate flow path separated from the drying flow path F10b, which is a flow path through which dry air moves. Accordingly, the shoes care device 1 according to one embodiment of the present invention includes the regeneration path F20, and when the dehumidifying material 331 is regenerated, air passing through the dehumidifying part 330 is not ventilated to the nozzle 820 but moves through the regeneration path F20.

The regeneration path F20 is a flow path branched from the connection path F10. The regeneration path F20 may be branched from the connection path F10 to form a path different from that of the drying flow path F10b of the connection path F10. The regeneration path F20 is connected to the sump 600.

The regeneration path F20 may be a section that connects the conversion flow path F10a and the sump 600.

The regeneration path F20 may be a section in which humid air separated from the dehumidifying part 330 moves.

The condenser 400 according to one embodiment of the present invention forms a regeneration path F20. Moisture separated from the dehumidifying material 331 may be condensed after moving to the condenser 400 along with air moving along the regeneration path F20. In addition, condensed water condensed in the condenser 400 may be moved to the sump 600 through the regeneration path F20, collected from a lower part of the sump 600, and then discharged to the drain tank 70, discharged to the outside, or pressed to the steam generator 700.

In the shoes care device 1 according to one embodiment of the present invention, when the drying module DM operates in the regeneration mode, the regeneration path F20 communicates with the conversion flow path F10a, and when the drying module DM operates in the moisture absorption mode, the regeneration path F20 and the conversion flow path F10 may not communicate with each other such that the regeneration path F20 and the conversion flow path F10 block each other.

Accordingly, when the dehumidifying part 330 is regenerated in the conversion flow path F10a, humid air containing moisture separated from the dehumidifying part 330 moves through the regeneration path F20.

In one embodiment of the present invention, the damper 350 may be formed in the form of a damper valve.

The damper 350 may be rotatably coupled to the module housing 200. The damper 350 may be coupled to the module housing 200 in a form accommodated in the module housing 200.

As described above, in the module housing 200, the dry air outlet 231 forming an inlet of the drying flow path F10b is formed as a passage of the connection path F10, and the wet air outlet 232 forming an inlet of the regeneration path F20 is formed.

The damper 350 controls a movement path of air passing through the dehumidifying material 331 in the module housing 200. Depending on the operation of the damper 350, the air passing through the dehumidifying material 331 may move into the inner cabinet 100 through the nozzle 820 or may move into the regeneration path F20.

The damper 350 may be configured to open the regeneration path F20 while blocking the drying flow path F10b, or to open the drying flow path F10b while blocking the regeneration path F20.

The damper 350 may be configured to selectively shield the dry air outlet 231 and the wet air outlet 232. The damper 350 may be configured to selectively seal the dry air outlet 231 and the wet air outlet 232.

The damper 350 may selectively block one of the dry air outlet 231 and the wet air outlet 232. When the damper 350 opens the dry air outlet 231 while blocking the wet air outlet 232, the air passing through the dehumidifying material 331 may move into the inner cabinet 100 through the nozzle 820, and when the damper 350 opens the wet air outlet 232 while blocking the dry air outlet 231, the air passing through the dehumidifying material 331 may be condensed while moving through the regeneration path F20.

In the shoes care device 1 according to one embodiment of the present invention, the damper 350 may be configured to be hinge-rotatable around a hinge axis 350a formed on one side. The hinge axis 350a of the damper 350 may be parallel to the third direction (Z direction). In addition, the shoes care device 1 may include a damper motor 351 configured to rotate the damper 350 around the hinge axis 350a of the damper 350. The damper motor 351 may be formed as an electric motor and may be configured to rotate the damper 350 bidirectionally.

When the damper 350 opens the dry air outlet 231 and seals the wet air outlet 232, the air inside the inner cabinet 100 moves along the connection path F10 and is circulated by sequentially passing through the inlet 203, the module housing 200 (the blowing part 310 and the dehumidifying part 330, the dry air outlet 231, the dry air duct 370, the nozzle duct 810, and the nozzle 820.

When the damper 350 seals the dry air outlet 231 and opens the wet air outlet 232, the air moves along the conversion flow path F10a and the regeneration path F20 and is circulated by sequentially passing through the module housing 200 (the blowing part 310, the heating part 310, and the dehumidifying part 330), the wet air outlet 232, and the condenser 400.

In one embodiment of the present invention, the controller 10 may control the damper motor 351 such that the damper 350 closes the dry air outlet 231 and opens the wet air outlet 232 when the heating part 320 is turned on. In addition, the controller 10 may control the damper motor 351 such that the damper 350 opens the dry air outlet 231 and closes the wet air outlet 232 when the heating part 320 is turned off.

Accordingly, by controlling the damper motor 351 by the controller 10, the damper 350 may open the drying flow path F10b and close the regeneration path F20 when the heating part 320 is turned off, and may close the drying flow path F10b and open the regeneration path F20 when the heating part 320 is turned on.

The damper motor 351 may be controlled individually in each of the first management device 2a and the second management device 2b.

Referring to FIG. 11, in the drying module A (DM1) of the first management device 2a, the damper 350 seals the wet air outlet 232 and opens the dry air outlet 231 of the second management device 2b, and in the drying module B (DM2) of the second management device 2b, when the damper 350 opens the wet air outlet 232 and seals the dry air outlet 231, the air in the conversion flow path F10a of the first management device 2a may flow through the drying flow path F10b, and the air in the conversion flow path F10a of the second management device 2b may flow through the regeneration path F20. Furthermore, in this case, the drying module A (DM1) of the first management device 2a may operate in the moisture absorption mode, and the drying module B (DM2) of the second management device 2b may operate in the regeneration mode.

In contrast, when in the drying module A (DM1) of the first management device 2a, the damper 350 opens the wet air outlet 232 and seals the dry air outlet 231, and in the drying module B (DM2) of the second management device 2b, the damper 350 seals the wet air outlet 232 and opens the dry air outlet 231, the air in the conversion flow path F10a of the first management device 2a may flow along the regeneration path F20, and the air in the conversion flow path F10a of the second management device 2b may flow along the drying flow path F10b. Furthermore, in this case, the drying module A (DM1) of the first management device 2a may operate in the regeneration mode, and the drying module B (DM2) of the second management device 2b may operate in the moisture absorption mode.

In both the drying module A (DM1) of the first management device 2a and the drying module B (DM2) of the second management device 2b, when the damper 350 seals the wet air outlet 232 and opens the dry air outlet 231, both the drying module A (DM1) and the drying module B (DM2) may operate in the moisture absorption mode.

In both the drying module A (DM1) of the first management device 2a and the drying module B (DM2) of the second management device 2b, when the damper 350 seals the dry air outlet 231 and opens the wet air outlet 232, both the drying module A (DM1) and the drying module B (DM2) may operate in the regeneration mode.

In the shoes care device 1 according to one embodiment of the present invention, the first management device 2a and the second management device 2b individually include the inner cabinet 100, the connection path F10, the blowing part 310, and the dehumidifying part 330. In addition, the shoes care device 1 includes the steam generator 700 and the steam valve 710. Accordingly, the degree of the supply of steam, the degree of dehumidification by the dehumidifying part 330, and the flow of air circulated along the connection path F10 may be different in each of the first management device 2a and the second management device 2b, and the first management device 2a and the second management device 2b may manage shoes under different conditions.

In addition, the first management device 2a and the second management device 2b include the module housing 200, the blowing part 310, the heating part 320, the dehumidifying part 330, and the drying flow path F10b, respectively. The air and condensed water moving in the first management device 2a and the air and condensed water moving in the second management device 2b move along different paths, thereby achieving accurate control intended in each of the first management device 2a and the second management device 2b. In this case, since the first management device 2a and the second management device 2b share and use the steam generator 700, the steam generator 700 can be efficiently utilized in the shoes care device 1, and the shoes care device 1 can efficiently utilize the space.

In addition, as described above, when the shoes are dried in one of the first management device 2a and the second management device 2b, the dehumidifying part 330 may be regenerated in the other, and the efficient management of the shoes and efficient use of the shoes care device 1 can be achieved.

In the shoes care device 1 according to one embodiment of the present invention, the first management device 2a and the second management device 2b each include the regeneration path F20 and the damper 350 individually.

The controller 10 may control the heating part 320 (the heater 321) and the damper 350 to interwork with each other.

The controller 10 may control the damper 350 to open the drying flow path F10b and close the regeneration path F20 when the heating part 320 is turned off, and may control the damper 350 to close the drying flow path F10b and open the regeneration path F20 when the heating part 320 is turned on.

The controller 10 may control each component of the shoes care device 1 such that air flowing into the module chamber 210 from the accommodation space 101 and passing through the dehumidifying part 330 moves along the drying flow path F10b when the heating part 320 is turned off (when the heater 321 of the heating part 320 is turned off), and the air moves along the regeneration path F20 when the heating part 320 is turned on (when the heater 321 of the heating part 320 is turned on).

Such control may be performed individually in each of the first management device 2a and the second management device 2b. Accordingly, since the movement path of air inside the module chamber 210 is changed depending on an operation of the heating part 320, the drying of the shoes and the regeneration of the dehumidifying part 330 can be effectively achieved.

The controller 10 may control the steam valve 710 and the heating part 320 to interwork with each other.

The controller 10 may control the steam valve 710 such that when the heating part 320 of the first management device 2a is turned off, the valve disk 715 closes or opens the first valve outlet 713, when the heating part 320 of the first management device 2a is turned on, the valve disk 715 closes the first valve outlet 713, when the heating part 320 of the second management device 2b is turned off, the valve disk 715 closes or opens the second valve outlet 714, and when the heating part 320 of the second management device 2b is turned on, the valve disk 715 closes the second valve outlet 714.

In this way, the supply of steam to the accommodation space 101 of the inner cabinet 100 and the operation of the heating part 320 inside the module housing 200 may interwork with each other to effectively perform the drying of the shoes and the regeneration of the dehumidifying part 330.

The shoes care device 1 according to one embodiment of the present invention may include a first sensor 361 and a second sensor 362 (see FIG. 9).

The first sensor 361 may be installed in the second module chamber 213 of the module housing 200, and the second sensor 362 may be installed in the third module chamber 214 of the module housing 200. The first sensor 361 may be configured to measure the temperature and/or humidity of the second module chamber 213, and the second sensor 362 may measure the temperature and/or humidity of the third module chamber 214.

The first sensor 361 measures the temperature and/or humidity of air before passing through the dehumidifying part 330, and the second sensor 362 measures the temperature and/or humidity of air after passing through the dehumidifying part 330.

The controller 10 may compare the temperature and/or humidity of the second module chamber 213 measured by the first sensor 361 with the temperature and/or humidity of the third module chamber 214 measured by the second sensor 362 to recognize a state and a change of the temperature and/or humidity inside the module housing, and may also check an operation state of the drying module DM.

The controller 10 may recognize the temperature and humidity of the second module chamber 213 measured by the first sensor 361, and the temperature and humidity of the third module chamber 214 measured by the second sensor 362 to recognize a change in the humidity inside the module housing 200. Accordingly, the degree of dehumidification by the dehumidifying part 330 may be checked, and the degree of regeneration of the dehumidifying part 330 may be checked.

In one embodiment, when the drying module DM operates in the moisture absorption mode, the controller 10 may control the drying module DM to stop operating in the moisture absorption mode and operate in the regeneration mode if a humidity change amount of the second module chamber 213 recognized by the first sensor 361 and a humidity change amount of the third module chamber 214 recognized by the second sensor 362 is less than or equal to a reference value.

In one embodiment, when the drying module DM operates in the regeneration mode, the controller 10 may control the drying module DM to stop operating in the regeneration mode if the humidity change amount of the second module chamber 213 recognized by the first sensor 361 and the humidity change amount of the third module chamber 214 recognized by the second sensor 362 is less than or equal to the reference value.

The shoes care device 1 according to one embodiment of the present invention further includes a third sensor 363 capable of measuring the amount of moisture adsorbed to the dehumidifying material 331, and the controller 10 may control the drying module DM to operate the regeneration mode until the amount of moisture measured by the third sensor 363 is less than or equal to a set value.

Specifically, the controller 10 may control all the heating parts 320 to operate until the amount of moisture measured by the third sensor 363 is less than or equal to the set value.

In this case, as illustrated in FIG. 11, the third sensor 363 may include a moisture sensor installed adjacent to the dehumidifying material 331 to measure the amount of moisture adsorbed to the dehumidifying material 331, and the type and number thereof may vary as necessary.

In this way, when the moisture adsorbed on the dehumidifying material 331 is sensed to exceed the reference value, the shoes care device 1 according to one embodiment of the present invention first regenerates all dehumidifying materials 331 until the moisture is less than or equal to the reference value. Accordingly, the dehumidifying material 331 can maintain an appropriate state for dehumidification all the time even when the shoes care device 1 operates to refresh the shoes.

FIG. 12 is a view illustrating a state in which the auxiliary shelf 900 is installed in the shoes care device 1 according to one embodiment of the present invention. FIG. 13a is a cross-sectional view illustrating an inner surface of the door illustrated in the shoes care device according to one embodiment of the present invention. FIGS. 13b to 13e are views illustrating an insertion groove and an insertion protrusion in more detail in the shoes care device according to one embodiment of the present invention. FIG. 14 is a perspective view illustrating the auxiliary shelf 900 in the shoes care device 1 according to one embodiment of the present invention. FIG. 15 is a view illustrating the auxiliary shelf 900 and the nozzle duct 810 in the shoes care device 1 according to one embodiment of the present invention. FIG. 16 is a view illustrating a state in which the nozzle duct 810 is coupled to a cross section taken along line 16-16′ of the auxiliary shelf 900 illustrated in FIG. 14. FIG. 17 is a view exemplarily illustrating a state in which the shoes are settled on the auxiliary shelf 900 in the shoes care device 1 according to one embodiment of the present invention.

The shoes care device 1 according to one embodiment of the present invention may include the inner cabinet 100, the outlet 203, the connection path F10, the blowing part 310, the dehumidifying part 330, and the auxiliary shelf 900.

As illustrated in FIG. 12, a shelf holder 910 is formed in the inner cabinet 100, and the auxiliary shelf 900 may be mounted on the shelf holder 910.

In this case, the auxiliary shelf 900 is installed to be mounted on the shelf holder 910, which is a part where the shoes can be settled on the upper surface thereof, and may spatially partition the accommodation space 101 of the inner cabinet 100.

Accordingly, the shoes may be accommodated in each space partitioned by the auxiliary shelf 900 in the inner cabinet 100 and then treated.

As described above, since the shoes care device 1 according to one embodiment of the present invention is used by mounting the auxiliary shelf 900 on the shelf holder 910 formed in the inner cabinet 100, a plurality of shoes can be efficiently treated even in one inner cabinet 100.

In the shoes care device 1 according to one embodiment of the present invention, the auxiliary shelf 900 may be installed to be detachable from the shelf holder 910. That is, the auxiliary shelf 900 may be configured to be separated from the shelf holder 910 in an outer direction of the inner cabinet 100.

Accordingly, when the foreign substances are accumulated on the auxiliary shelf 900 and needs to be removed, or when contaminants on the auxiliary shelf 900 needs to be removed, the user can separate the auxiliary shelf 900 from the inner cabinet 100 and perform cleaning and cleaning.

In addition, even if the auxiliary shelf 900 needs to be inspected and replaced, a predetermined operation may be performed after the auxiliary shelf 900 is separated from the inner cabinet 100.

As described above, in the shoes care device 1 according to one embodiment of the present invention, since the auxiliary shelf 900 is detached from the shelf holder 910, the auxiliary shelf 900 may be easily managed.

In the shoes care device 1 according to one embodiment of the present invention, the auxiliary shelf 900 may have an auxiliary isolation rib 902 formed to protrude upwards from an upper surface thereof.

That is, as illustrated in FIG. 14, the auxiliary isolation rib 902 protrudes from the upper surface of the auxiliary shelf 900, and the bottom surfaces of the shoes may be settled on the auxiliary isolation rib 902.

When the shoes are settled on the upper surface of the planar auxiliary shelf 900, the upper surface of the auxiliary shelf 900 and the bottom surfaces of the shoes are mostly in close contact with each other. In this case, since it is difficult for air to get in contact with the bottom surfaces of the shoes, there may be any difficulty treating the bottom surfaces of the shoes. Further, when water is present between the auxiliary shelf 900 and the shoes, it may be difficult to move or evaporate such water.

Therefore, preferably, a separation space through which air or water may move between the upper surface of the auxiliary shelf 900 and the bottom surfaces of the shoes.

As described above, in the shoes care device 1 according to one embodiment of the present invention, since the auxiliary isolation rib 902 is formed on the upper surface of the auxiliary shelf 900, the separation space for a movement of air or water may be formed between the upper surface of the auxiliary shelf 900 and the bottom surfaces of the shoes.

In the shoes care device 1 according to one embodiment of the present invention, the auxiliary isolation rib 902 may be formed in an oblique direction between the front surface and the rear surface of the inner cabinet 100.

That is, as illustrated in FIGS. 14 and 17, the auxiliary isolation ribs 902 may be formed in the oblique direction so as not to be parallel to the horizontal or vertical direction of the planar auxiliary shelf 900.

In general, the protrusion structure for preventing slipping may be formed on the bottom surfaces of the shoes, and such a protrusion structure may be formed on the bottom surfaces of the shoes along a transverse direction and/or a vertical direction.

Accordingly, when the auxiliary isolation rib 902 is formed horizontally or vertically on the auxiliary shelf 900, a relatively large part may be in parallel with a direction of the protrusion structure formed on the bottom surfaces of the shoes.

In this case, when the protrusion structure formed on the bottom surfaces of the shoes engages with the auxiliary isolation rib 902, the shoes and the upper surface of the auxiliary shelf 900 come into relatively more contact, and as described above, the larger the contact area may result in some disadvantages in terms of the function and maintenance of the shoes care device 1.

Accordingly, the auxiliary isolation rib 902 may be preferably formed in the oblique direction such that the protrusion structure formed on the bottom surfaces of the shoes are not parallel to the auxiliary isolation rib 902 as much as possible.

As described above, in the shoes care device 1 according to one embodiment of the present invention, since the auxiliary isolation rib 902 is formed in the oblique direction, an area in which the upper surface of the auxiliary shelf 900 and the bottom surfaces of the shoes come into contact can be further reduced.

In the shoes care device 1 according to one embodiment of the present invention, the auxiliary shelf 900 may be provided with an auxiliary outer rib 903 continuously protruding upwards along the circumferential surface.

That is, as illustrated in FIGS. 14 and 17, the circumferential surface of the auxiliary shelf 900 may be formed to protrude upwards from the remaining parts. Accordingly, water staying on the upper surface of the auxiliary shelf 900 may be blocked by the auxiliary outer rib 903, and may be blocked from moving outside the circumferential surface of the auxiliary shelf 900.

In this way, in the shoes care device 1 according to one embodiment of the present invention, since the auxiliary outer rib 903 is formed along the circumferential surface of the auxiliary shelf 900, water moving on the auxiliary shelf 900 may be prevented from flowing to an unintended part.

In the shoes care device 1 according to one embodiment of the present invention, the auxiliary shelf 900 may be formed in a convex cross-sectional shape from the central part of the inner cabinet 100 to opposite sides. That is, similarly to the main shelf 40, the auxiliary shelf 900 may be formed in a convex shape such that the central part thereof is higher than the opposite sides.

Accordingly, since water staying in the central part of the auxiliary shelf 900 may flow to opposite sides, the occurrence of residual water can be minimized on the auxiliary shelf 900.

In addition, considering the bottom surfaces of shoes formed mostly flat, the upper surface of the auxiliary shelf 900 may have a convex cross-sectional shape, which can minimize a contact area between the upper surface of the auxiliary shelf 900 and the bottom surfaces of the shoes.

In this way, since the central part of the auxiliary shelf 900 is convexly formed, the shoes care device 1 according to one embodiment of the present invention prevents water from accumulating in the central part of the auxiliary shelf 900, and minimizes an area where the upper surface of the auxiliary shelf 900 is in contact with the bottom surfaces of the shoes.

The shoes care device 1 according to one embodiment of the present invention may further include the nozzle duct 810 and the nozzle 820.

The nozzle duct 810 is a part installed inside the inner cabinet 100 and forming a passage of air, and one end thereof is coupled to the inner cabinet 100 and the other thereof end is coupled to the nozzle 820 to form a passage through which air moves to the nozzle 820.

In this case, the nozzle duct 810 may have an upper discharge port 811 opened upwards. For example, since the upper discharge port 811 is formed on a part of the upper surface of the nozzle duct 810, some of the air moving into the nozzle duct 810 may be discharged to the accommodation space 101 through the upper discharge port 811.

Meanwhile, since the nozzle duct 810 is installed to protrude inside the inner cabinet 100, the position where the nozzle 820 is disposed inside the inner cabinet 100 may vary.

The nozzle 820 is a part coupled to the end of the nozzle duct 810 such that the shoes can be inserted in the inner cabinet 100, and air passing through the connection passage F10 may be sprayed into the shoes inside the inner cabinet 100 through the nozzle 820.

Specifically, the nozzle 820 may inject air smoothly into the shoes by injecting air in a state where the nozzle is inserted into the shoes.

In I this case, the nozzle 820 may have a lower discharge port 821 opened downwards so as to spray air into the shoes. For example, the lower discharge port 821 is formed in the end of the nozzle 820, and air may be discharged downwards through the lower discharge port 821 in a state where the end of the nozzle 820 is inserted into the shoe.

The nozzle duct 810 may be hinge-coupled to the inner cabinet 100. That is, a nozzle duct hinge axis 813 formed on one end of the nozzle duct 810 is coupled to the inner cabinet 100, and the nozzle duct 810 may be rotated around the nozzle duct hinge axis 813.

The nozzle duct 810 may be installed to protrude ahead from a rear wall of the inner cabinet 100.

Accordingly, depending on whether the nozzle 820 is used or not, the nozzle duct 810 is hinge-rotated inside the inner cabinet 100 and the angle is adjusted such that the nozzle 820 can be displaced in various positions on an inner space of the inner cabinet 100.

The nozzle 820 may be hinge-coupled to the nozzle duct 810. That is, the nozzle 820 may be coupled to a nozzle hinge axis 825 formed in the other end of the nozzle duct 810, and the nozzle 820 may be rotated around the nozzle hinge axis 825.

When the angle of the nozzle duct 810 is changed and the nozzle duct 810 is inclinedly disposed, it may be difficult for the nozzle 820 to get inserted into the upper surfaces of the shoes if the nozzle 820 is also inclined integrally with the nozzle duct 810.

Accordingly, even if the nozzle duct 810 is inclinedly disposed, the angle may be preferably adjusted such that the nozzle 820 is not inclined by more than a predetermined angle.

In this case, the auxiliary shelf 900 may have a cutout portion 901 with a width corresponding to an outer diameter of the nozzle duct 810. That is, as illustrated in FIG. 14, the central part of the auxiliary shelf 900 may be provided with a cutout portion 901 of which one surface is opened and inserted inside.

Further, as illustrated in FIGS. 12 and 16, the nozzle duct 810 may be inserted into the cutout portion 901 when the auxiliary shelf 900 is mounted on the shelf holder 910.

That is, in the cutout portion 901 of the auxiliary shelf 900, since a part facing the rear wall of the inner cabinet 100 is opened, the auxiliary shelf 900 may be pushed from the front surface of the inner cabinet 100 to the rear wall.

In this case, since the nozzle duct 810 is inserted into the cutout portion 901 of the auxiliary shelf 900 and the width of the cutout portion 901 corresponds to an outer diameter of the nozzle duct 810, interference by the nozzle duct 810 may not occur during the mounting process of the auxiliary shelf 900.

In the shoes care device 1 according to one embodiment of the present invention, when the auxiliary shelf 900 is mounted in the inner cabinet 100, since the nozzle duct 810 is inserted into the cutout portion 901 of the auxiliary shelf 900, the auxiliary shelf 900 may be mounted while minimizing the interference with the nozzle duct 810.

In the shoes care device 1 according to one embodiment of the present invention, the upper discharge port 811 may be disposed on an upper part of the auxiliary shelf 900 and the lower discharge port 821 may be disposed below the auxiliary shelf 900 based on a state in which the nozzle duct 810 is inserted into the cutout portion 901 and an upper surface of the nozzle 820 is in contact with the auxiliary shelf 900.

That is, as illustrated in FIGS. 12 and 15, when the auxiliary shelf 900 is mounted on the shelf holder 910 to spatially partition the accommodation space 101 of the inner cabinet 100, the upper discharge port 811 may be disposed in an upper space thereof, and the lower discharge port 821 may be disposed in the lower space thereof.

Accordingly, when a plurality of shoes are accommodated in the accommodation space 101 of the inner cabinet 100, the shoes accommodated in the upper shelf 900 may be treated by the air discharged from the upper outlet 811, and the shoes accommodated in the lower shelf 900 may be treated by the air discharged from the lower outlet 821.

As described above, with the auxiliary shelf 900 mounted in the inner cabinet 100, the upper discharge port 811 discharges air to the upper part of the auxiliary shelf 900 and the lower discharge port 821 discharges air to the lower part of the auxiliary shelf 900. Accordingly, the shoes care device 1 according to one embodiment of the present invention can efficiently treat the shoes by placing the shoes above and below the auxiliary shelf 900.

In the shoes care device 1 according to one embodiment of the present invention, the nozzle 820 may include a nozzle body 822 hinge-coupled to the nozzle duct 810 and a nozzle protrusion 823 protruding downwards from the nozzle body 822 and having the lower discharge port 821 formed in the end thereof.

In this case, the upper surface of the nozzle body 822 can be attached to the lower surface of the auxiliary shelf 900 by magnetic force.

The nozzle 820 may be dropped downwards when an unintended external force is applied to the nozzle 820, or the performance of the part supporting the nozzle is degraded due to long-term use.

Accordingly, the upper surface of the nozzle body 822 may be attached to the lower surface of the auxiliary shelf 900 by the magnetic force, and the nozzle 820 may be held on the lower surface of the auxiliary shelf 900.

In this case, a magnetic body may be disposed in at least one of the nozzle body 822 and the auxiliary shelf 900, and the nozzle body 822 and the auxiliary shelf 900 may be made of a material that can be attached by the magnetic force.

In the shoes care device 1 according to one embodiment of the present invention, since the upper surface of the nozzle body 822 and the lower surface of the auxiliary shelf 900 are magnetically attached to each other, the lower surface of the auxiliary shelf 900 and the upper surface of the nozzle body 822 may be attached to each other.

In the shoes care device 1 according to one embodiment of the present invention, the auxiliary shelf 900 may be in close contact with the upper surface of the nozzle duct 810 by inclinedly forming a front lower surface of the cutout portion 901.

That is, as illustrated in FIG. 16, in order to closely adhere the upper surface of the nozzle duct 810 and the lower surface of the auxiliary shelf 900, the front lower surface of the cutout portion 901 may be inclined in a shape corresponding to the upper surface of the nozzle duct 810.

Accordingly, the auxiliary shelf 900 and the nozzle duct 810 can maintain a more stable contact state by minimizing a gap between the lower surface of the auxiliary shelf 900 and the upper surface of the nozzle duct 810.

In this way, in the shoes care device 1 according to one embodiment of the present invention, since the front lower surface of the cutout portion 901 in close contact with the upper surface of the nozzle duct 810 is formed to be inclined, the lower surface of the auxiliary shelf 900 and the upper surface of the nozzle duct 810 can be in stable contact with each other.

In the shoes care device 1 according to one embodiment of the present invention, the nozzle 820 may further include a nozzle handle 826 formed on a front surface of the nozzle body 822, and the auxiliary shelf 900 may have a handle groove 904 formed in a part corresponding to an upper part of the nozzle handle 826.

That is, as illustrated in FIGS. 12 and 16, since the nozzle handle 826 is formed in the nozzle body 822, the user can easily adjust the angle of the nozzle duct 810 by holding the nozzle handle 826 and applying force without touching the nozzle duct 810.

In this case, when the part where the nozzle handle 826 is formed is covered by the auxiliary shelf 900, it may be difficult for the user to recognize the position of the nozzle handle 826 or grasp the nozzle handle 826.

Accordingly, since the handle groove 904 is formed in a part of the auxiliary shelf 900 corresponding to the upper part where the nozzle handle 826 is formed, the user can more easily recognize the position the nozzle handle 826, or grasp the nozzle handle 826.

In this way, in the shoes care device 1 according to one embodiment of the present invention, since the handle groove 904 is formed in the part of the auxiliary shelf 900 corresponding to the upper part of the nozzle handle 826, the angle of the nozzle can be more easily changed through the nozzle handle 826.

The shoes care device 1 according to one embodiment of the present invention may further include the door 30, and the door 30 may include an accommodation groove 35 formed on the inner surface to correspond to the planar shape of the auxiliary shelf 900 and capable of accommodating the auxiliary shelf 900.

That is, as illustrated in FIG. 13, since the accommodation groove 35 is formed on the inner surface of the door 30, the auxiliary shelf 900 in an unused state may be accommodated in the accommodation groove 35.

As described above, the auxiliary shelf 900 is a component configured to simultaneously perform treatment on several shoes in one inner cabinet 100, and may not be used during the treatment of one shoe.

In this case, since storing the auxiliary shelf 900 in a separate space may be considerably cumbersome from the user's point of view, the auxiliary shelf 900 can be preferably accommodated in the shoes care device 1.

Accordingly, since the shoes care device 1 according to one embodiment of the present invention has the accommodation groove 35 formed on the inner surface of the door 30 to accommodate the auxiliary shelf 900, the auxiliary shelf 900 in the unused state can be conveniently and effectively stored.

In the shoes care device 1 according to one embodiment of the present invention, the accommodation groove 35 may be formed such that the lower part thereof is spaced apart from the auxiliary shelf 900 in a state where the auxiliary shelf 900 is accommodated.

That is, as illustrated in FIG. 13, a predetermined gap may be formed between the auxiliary shelf 900 and the upper part of the accommodation groove 35.

As described above, when the condensed water flows down along the inner surface of the door 30, the condensed water may remain in the accommodation groove 35. Specifically, when both the auxiliary shelf 900 and the accommodation groove 35 are in close contact with each other, bacteria and mold may be generated by the condensed water remaining therebetween.

Accordingly, preferably, as the lower part of the accommodation groove 35 is spaced apart from the auxiliary shelf 900 by the predetermined gap, the condensed water flowing down to the lower part of the accommodation groove 35 is made to evaporate when air is circulated.

In addition, when the user wants to use the auxiliary shelf 900 accommodated in the accommodation groove 35, it may be difficult for the user to separate the auxiliary shelf 900 from the accommodation groove 35 if both the auxiliary shelf 900 and the accommodation groove 35 are in close contact with each other.

Accordingly, as the lower part of the accommodation groove 35 is spaced apart from the auxiliary shelf 900 by the predetermined gap, when the auxiliary shelf 900 is pushed into the corresponding gap, the upper part of the auxiliary shelf 900 is made to protrude from the accommodation groove 35 so that the user can easily separate the auxiliary shelf 900 from the accommodation groove 35.

Since the lower part of the accommodation groove 35 is spaced apart from the auxiliary shelf 900 by the predetermined gap, the shoes care device 1 according to one embodiment of the present invention may prevent moisture from remaining and causing contamination between the auxiliary shelf 900 and the accommodation groove 35, and may easily detach the auxiliary shelf 900 from the accommodation groove 35.

In the shoes care device 1 according to one embodiment of the present invention, the auxiliary shelf 900 may be attached to the accommodation groove 35 by the magnetic force.

The auxiliary shelf 900 in the unused state needs to be stably accommodated in the accommodation groove 35, and needs to be prevented from being unintentionally detached from the accommodation groove 35 even in vibration and impact caused by opening and closing the door 30.

Accordingly, the auxiliary shelf 900 may be attached to the accommodation groove 35 by the magnetic force, and the auxiliary shelf 900 in the unused state may be held in the accommodation groove 35.

In this case, a magnetic material may be disposed in at least one of the accommodation groove 35 and the auxiliary shelf 900, and the accommodation groove 35 and the auxiliary shelf 900 may be made of a material that can be attached by the magnetic force.

In this way, in the shoes care device 1 according to one embodiment of the present invention, since the auxiliary shelf 900 and the accommodation groove 35 are attached to each other by the magnetic force, the auxiliary shelf 900 can be stably attached to the accommodation groove 35.

In the shoes care device 1 according to one embodiment of the present invention, the auxiliary shelf 900 may be accommodated in the accommodation groove 35 in a shape where the cutout portion 901 is disposed in the lower part thereof.

That is, the auxiliary shelf 900 having a L-shaped plane by forming cutout portion 901 may be accommodated in the accommodation groove 35 in a shape where an open surface of the cutout portion 901 is disposed in the lower part thereof. Accordingly, the auxiliary shelf 900 may be accommodated in the accommodation groove 35 in a shape where the handle groove 904 formed on the auxiliary shelf 900 is disposed in the upper part thereof.

As described above, preferably, the lower part of the accommodation groove 35 is spaced apart from the auxiliary shelf 900 by the predetermined gap such that the condensed water flowing down to the lower part of the accommodation groove 35 is evaporated when air is circulated.

Accordingly, the cutout portion 901 with a relatively large open area is disposed in the lower part of the accommodation groove 35 so that the lower part of the accommodation groove 35 can has a larger separation part that that of the auxiliary shelf 900.

In addition, when the user wants to take out the auxiliary shelf 900 from the accommodation groove 35, a handle portion that is easy to grip may be disposed on the upper part, which can be more conveniently used in the user's point of view.

As described above, since the shoes care device 1 according to one embodiment of the present invention accommodates the auxiliary shelf 900 in the accommodation groove 35 such that the cutout portion 901 is disposed downwards, a more separation part is secured between the lower part of the accommodation groove 35 and the auxiliary shelf 900, and the auxiliary shelf 900 can be easily separated from the accommodation groove 35 through the handle groove 904.

The shoe care device 1 according to an embodiment of the present disclosure may further include a door 30, and the door 30 may include an accommodation groove 35 provided on the inner surface to correspond to the planar shape of the auxiliary shelf 900 to be capable of the auxiliary shelf 900, and an insertion groove 36a provided at the lower end of the accommodation groove 35 in an open-top shape.

In this case, the auxiliary shelf 900 may have an insertion protrusion 905 protruding from the lower end in the state in which the auxiliary shelf 900 is accommodated in the accommodation groove 35 to be insertable into the insertion groove 36a.

As described above, the auxiliary shelf 900 may be accommodated in the accommodation groove 35 provided on the inner surface of the door 30 when the auxiliary shelf is not in use. However, the auxiliary shelf 900 may be unintentionally separated from the accommodation groove 35 due to shock, vibration, or the like that may occur in the process of opening and closing the door 30.

Therefore, except for the case where the auxiliary shelf 900 is intentionally separated from the door 30, it may be desirable to ensure that the auxiliary shelf 900 is accommodated stably in the accommodation groove 35 by allowing the insertion protrusion 905 to be inserted into the insertion groove 36a when the auxiliary shelf 900 is accommodated in the accommodation groove 35.

In this way, since the shoe care device 1 according to the present embodiment is configured such that the insertion protrusion 905 of the auxiliary shelf 900 is inserted into the insertion groove 36a in the door 30 while the auxiliary shelf 900 is accommodated in the accommodation grove 35, it is possible to prevent the auxiliary shelf 900 from being unintentionally separated from the accommodation groove 35.

Meanwhile, an insertion groove drain hole 36c configured to discharge condensed water may be provided inside the insertion groove 36a so as to ensure that the condensed water generated due to steam or the like flowing into the auxiliary shelf 900 accommodated in the accommodation groove 35 can be smoothly discharged.

In the shoe care device 1 according to an embodiment of the present disclosure, the insertion groove 36a may have an insertion rib 36b protruding from one surface toward the other opposite surface inside the insertion groove.

In this case, the insertion protrusion 905 may be inserted into the space between the insertion rib 36b and the other surface inside the insertion groove 36a.

That is, as illustrated in FIGS. 13b to 13e, one surface of the insertion protrusion 905 inserted into the insertion groove 36a may be in contact with the other surface of the insertion groove 36a. In addition, the other surface of the insertion protrusion 905 may be in contact with the insertion rib 36b protruding from the one surface of the insertion groove 36a.

Therefore, even when movement occurs in the insertion protrusion 905 inserted into the insertion groove 36a, the movement may be restricted since the insertion protrusion 905 is supported between the insertion rib 36b and the other surface inside the insertion groove 36a.

In this way, since the shoe care device 1 according to the present embodiment is configured such that the insertion groove 36a provided inside the insertion groove 36a supports the insertion protrusion 905 of the auxiliary shelf 900, the insertion protrusion 905 can be supported more stably.

In this case, the insertion rib 36b may be provided to be continuous along the longitudinal direction of the insertion groove 36a. However, in consideration of a coring structure or the like, it may be desirable to provide a plurality of insertion ribs 36b which are discontinuous along the longitudinal direction of the insertion groove 36a.

In the shoe care device 1 according to an embodiment of the present disclosure, the width di of the insertion groove 36a may be relatively larger than the sum of the thickness dp of the insertion protrusion 905 and the thickness dr of the insertion rib 36b.

That is, as illustrated in FIG. 13e, since the gap between the insertion rib 36b and the other surface inside the insertion groove 36a is relatively larger than the thickness dp of the insertion protrusion 905, a certain amount of free space may be formed in the portion of the insertion groove 36a where the insertion protrusion 905 is inserted.

When there is not a certain amount of free space in the portion of the insertion groove 36a where the insertion protrusion 905 is inserted, it may not be easy to insert the insertion protrusion 905 into the insertion groove 36a.

In addition, in order to separate the auxiliary shelf 900 from the accommodation groove 35, it is necessary to tilt the auxiliary shelf 900 at a predetermined angle. However, when there is not a certain amount of free space in the portion of the insertion groove 36a where the insertion protrusion 905 is inserted, it may not be easy to separate the auxiliary shelf 900 since the auxiliary shelf 900 cannot be tilted.

Therefore, it may be desirable to form the width di of the insertion groove 36a to be relatively larger than the sum of the thickness dp of the insertion protrusion 905 and the thickness dr of the insertion rib 36b such that the auxiliary shelf 900 can be tilted at a predetermined angle θ (e.g., 5° to 7°) even when the insertion protrusion 905 is inserted into the insertion groove 36a.

In this way, in the shoe care device 1 according to the present embodiment, since a certain amount of free space is formed in the portion of the insertion groove 36a where the insertion protrusion 905 is inserted, the auxiliary shelf 900 can be tilted at the predetermined angle even when the insertion protrusion 905 is inserted into the insertion groove 36a.

In the shoe care device 1 according to an embodiment of the present disclosure, the length Lp of the insertion protrusion 905 may be relatively larger than the thickness dp of the insertion protrusion 905.

That is, as illustrated in FIGS. 13c and 13d, since the insertion depth of the insertion protrusion 905 is relatively larger than the thickness of the insertion protrusion 905, the insertion protrusion 905 can be inserted into the insertion groove 36a sufficiently deep compared to the width of the insertion groove.

As described above, when the auxiliary shelf 900 is tilted at the predetermined angle θ even when the insertion protrusion 905 is inserted into the insertion groove 36a, there is a risk that the insertion protrusion 905 may be separated from the insertion groove 36a in the state in which the user does not fully separate the auxiliary shelf 900 from the accommodation groove 35.

Therefore, it is necessary to secure a sufficient insertion depth of the insertion protrusion 905 when the auxiliary shelf 900 is tilted at the predetermined angle θ.

Through this, as illustrated in FIG. 13d, when the auxiliary shelf 900 is tilted at the predetermined angle θ, the lower end of the insertion protrusion 905 is supported on the other surface inside the insertion groove 36a and the upper end of the insertion protrusion 905 is supported on the insertion rib 36b, thereby limiting the tilt of the auxiliary shelf 900 and preventing the insertion protrusion 905 from being separated from the insertion groove 36a.

In this way, in the shoe care device 1 according to the present embodiment, since the insertion protrusion 905 is inserted into the insertion groove 36a sufficiently deep compared to the width of the insertion groove, it is possible to prevent the insertion protrusion 90 from being unintentionally separated from the insertion groove 36a even when the auxiliary shelf 900 is tilted at the predetermined angle.

As described above, in the shoe care device 1 according to an embodiment of the present disclosure, since the auxiliary shelf 900 is magnetically attached to the accommodation groove 35, the auxiliary shelf 900 can be stably attached to the accommodation groove 35.

Here, the auxiliary shelf 900 may include a magnetic metal in a portion thereof, and the accommodation groove 35 may include a magnetic material that is capable of attracting the metal of the auxiliary shelf 900.

It may be desirable for the auxiliary shelf 900 to have a certain degree of rigidity in view of the fact that shoes are placed on the upper surface of the auxiliary shelf. Accordingly, the auxiliary shelf 900 may be strengthened in rigidity by partially including metal.

Especially, considering the structure in which the auxiliary shelf 900 and the accommodation groove 35 are magnetically attached to each other, it may be desirable for a portion of the auxiliary shelf 900 to include a magnetic metal. In addition, the accommodation groove 35 may include a magnetic material so that the auxiliary shelf 900 can be magnetically attached to the accommodation groove.

As described above, in the shoe care device 1 according to the present embodiment, since the auxiliary shelf 900 includes metal that can be magnetically attached to the accommodation groove 35, the auxiliary shelf 900 can be strengthened in rigidity while being easily attached to/detached from the accommodation groove 35.

Hereinabove, a specific embodiment of the present invention is described and illustrated, but the present invention is not limited to the disclosed embodiment, and it may be appreciated by those skilled in the art that the exemplary embodiment can be variously modified and transformed to another specific embodiment without departing from the spirit and the scope of the present invention. Therefore, the scope of the present invention will not be defined by the described embodiment, but defined by the technical spirit disclosed in the claims.
