Abstract

The present invention relates to a laundry treating apparatus in which, in a case where a drying operation is performed, driving of a compressor is maintained until the drying operation is finished or drying of the laundry is completed, while a first heater and a second heater are driven together in the driving of the compressor so as to raise an internal temperature of an inner case to a set temperature or above.

Description

Technical Field

[0001] The present invention relates to a laundry processing device and a control method thereof, and more particularly to a laundry processing device capable of performing laundry refreshing operations such as sterilizing, removing creases, deodorizing, and drying by supplying steam and hot air to the laundry, and a control method thereof. Background Art

[0002] Generally, among laundry treating apparatuses, a drying machine having a rotating drum and a laundry care machine having an inner case in which laundry is placed in a floating state may perform a drying operation of removing moisture from the laundry.

[0003] Creases or wrinkles on clothes can only be removed if moisture content, temperature, and physical force are satisfied. However, the drying machine and clothing care machine are set to a range where it is difficult to ensure that all three factors are satisfied during the drying operation.

[0004] As a result, although the drying machine and the clothing care machine may dry the clothes while supplying hot air, creases or wrinkles on the clothes may not be easily removed.

[0005] Figure 1 It is a diagram showing the principle of removing creases from clothes.

[0006] Reference Figure 1 (a), the fibers constituting the clothing L may be woven in the order of 1, 2, 3, 4, and 5. That is, fiber 1, fiber 2, fiber 3, fiber 4, and fiber 5 may be connected by physical bonding I.

[0007] However, depending on their internal chemical structure, such fibers may form chemical bonds II between the fibers when they rub or come into contact with each other, such as covalent bonds, hydrogen bonds, or intermolecular bonds. For example, although fiber 1 and fiber 3 may not be physically bonded I, they may be connected by chemical bond II. Similarly, fiber 3 and fiber 5 may not be physically bonded I, but may be connected by chemical bond II.

[0008] Therefore, the chemical bond II occurs intensively in at least a portion of the clothing L, causing a change in the arrangement or configuration of the fibers producing the chemical bond II, ultimately resulting in creases or wrinkles.

[0009] Since the creases and wrinkles are caused by the chemical bond II, they cannot be removed by simple physical force. Only by breaking the chemical bond II can the creases and wrinkles be removed.

[0010] Reference Figure 1(b) To remove the creases and wrinkles, water is first required to release the chemical bonds II. If water is introduced between the chemical bonds II between the fibers, the chemical bonds II will be weakened or released.

[0011] The amount of moisture required to remove creases and wrinkles can be determined by the moisture content of the clothing. It is known that a moisture content between 5% and 45% is generally required. Therefore, a moisture content between 5% and 45% can be defined as the removal moisture content.

[0012] If the clothes contain more water than the removal moisture content, the water will further combine the fibers, resulting in no crease and wrinkle removal effect. If the clothes contain less water than the removal moisture content, the chemical bonds II between the fibers cannot be removed, so there is no crease and wrinkle removal effect.

[0013] Reference Figure 1 (c) To remove the creases and wrinkles, heat or energy is required to release the chemical bonds II. If the chemical bonds II between the fibers are heated, the bonds between the fibers in chemical bonds II may weaken. The heat or energy required to remove the creases and wrinkles can be achieved by exceeding a set temperature. The set temperature is higher than room temperature and can be set to, for example, 36°C.

[0014] When water is introduced between the fibers and the temperature reaches a high temperature exceeding a set temperature, the chemical bond II may become extremely weak.

[0015] Reference Figure 1 (d) In order to remove the creases and wrinkles, a physical force capable of changing the arrangement of the fibers is required. The physical force may include a tensile force capable of causing the fibers to be arranged in an order of physical bonding. The physical force capable of generating the tensile force may be defined as a physical force for removal.

[0016] Reference Figure 1 (e) When chemical bonds II occur in the fibers constituting the clothing L, resulting in creases and wrinkles in the clothing, if the conditions for removing the moisture content, setting the temperature, and removing the physical force are all met, the chemical bonds II can be removed, and the fibers can be aligned in the order connected by the physical bonds I. As a result, the wrinkles and creases can be removed.

[0017] As a result, it can be considered that the removal of moisture content, setting temperature, and removing physical force are equivalent to the removal conditions of creases and wrinkles.

[0018] Figure 2 FIG. 1 is a diagram showing a state in which clothes are dried in a dryer.

[0019] The dryer may accommodate laundry in a drum D and perform a drying operation of removing moisture from the laundry by supplying hot air.

[0020] Reference Figure 2 (a), in the early stage of the drying operation, the moisture content of the laundry L is generally equivalent to a moisture content above the removal moisture content, and sufficient heat H may not be applied to the inside of the drum D.

[0021] Even if the drum D rotates, since the clothes having a high moisture content are entangled with each other, it is impossible to apply a proper stretching force to the clothes.

[0022] As a result, at the initial stage of the drying operation, the removal conditions cannot be satisfied, and thus the creases of the laundry cannot be removed.

[0023] Reference Figure 2 (b) In the middle of the drying operation, the moisture content of the clothes L may reach the removal moisture content. However, since a large amount of moisture contained in the clothes L is vaporized, most of the heat H supplied to the inside of the drum D is consumed as vaporization heat.

[0024] Therefore, the temperature inside the drum D cannot reach a set temperature or above. Thus, the removal condition cannot be fully satisfied in the middle of the drying operation, and thus the creases on the clothes cannot be removed.

[0025] Reference Figure 2 (c) At the end of the drying operation, most of the moisture contained in the clothes L is evaporated, so the amount of heat absorbed as vaporization heat can be sharply reduced.

[0026] Therefore, the temperature inside the drum D rises rapidly to above the set temperature, thereby satisfying the removal temperature.

[0027] In addition, since the laundry is in a dried state, the laundry can be separated from each other and fall in the rotating drum D, thereby also achieving the removal of physical force.

[0028] However, since most of the clothes L have been dried, the moisture content of the clothes is lower than the removal moisture content.

[0029] Therefore, at the end of the drying operation, the removal conditions are not satisfied, and the creases of the laundry cannot be removed.

[0030] As a result, it is difficult for the dryer to form a section in which all the removal conditions are satisfied during the entire drying process.

[0031] Therefore, during the drying operation performed by the existing clothes treating apparatus, there is a fundamental problem that creases of clothes cannot be removed.

[0032] As a result, there are limitations such as the need for users to perform additional ironing on the clothes to remove creases, or the need to throw ice cubes into the drum at the end of the drying process to meet the moisture content removal condition.

[0033] In recent years, there have also been clothes treating apparatuses that can spray steam at the end of a drying operation in order to satisfy removal conditions at the end of the drying operation.

[0034] However, although the existing clothes processing device can remove creases, there is a problem that it is necessary to supply additional water to the dried clothes at the end of the drying operation and dry them again, which not only prolongs the drying operation but also inevitably wastes energy.

[0035] Furthermore, existing laundry processing devices have control limitations. Specifically, the compressor must be interrupted to prevent excess power consumption during the operation of the heater to supply steam. Consequently, steam must be supplied after the drying process is complete, and the compressor must be activated again to continue drying. Alternatively, the compressor must be interrupted midway through the drying process, steam must be supplied, and then the compressor must be activated again. This not only prolongs the drying process but also significantly reduces drying efficiency.

[0036] Existing clothes treating apparatuses have the problem of being unable to automatically remove creases and wrinkles from clothes during a drying operation for removing moisture from the clothes. Summary of the Invention

[0037] Problem to be solved

[0038] The problem to be solved by the present invention is to provide a clothes treating device capable of removing creases and wrinkles of clothes during a drying operation.

[0039] An object of the present invention is to provide a clothes treating apparatus capable of maintaining the driving of a compressor without interruption even when steam is supplied to remove creases and wrinkles from clothes.

[0040] An object of the present invention is to provide a clothes treating apparatus capable of ensuring a section satisfying a removal condition during a drying operation for removing moisture from clothes.

[0041] The problem to be solved by the present invention is to provide a clothes treating device that can remove creases and wrinkles of clothes while maintaining energy efficiency and preventing drying delay during a drying operation.

[0042] Technical solutions to the problem

[0043] In order to solve the above-mentioned problems, the present invention provides a clothing processing device, which includes: a box body; an inner shell body, which is arranged inside the box body and accommodates clothes; a mechanical chamber, which is provided with a heating part for supplying hot air to the inside of the inner shell body and a steam supply part for supplying steam; a control part, which is arranged in the mechanical chamber and performs a drying operation of drying the clothes by controlling the heating part and the steam supply part; and a temperature sensor, which is arranged in the inner shell body or the mechanical chamber and senses the temperature of the air inside the inner shell body.

[0044] The heating unit may include: a circulation duct that circulates air exhausted from the inner shell; a heat exchanger provided in the circulation duct that dehumidifies and reheats the air; and a compressor that compresses a refrigerant that exchanges heat with the air and supplies the refrigerant to the heat exchanger.

[0045] The steam supply part may include a steam housing storing water for generating the steam; a first heater accommodated in the steam housing and generating the steam by heating the water; and a second heater spaced apart from the first heater and generating the steam by heating the water.

[0046] In a case where the drying operation is performed, the control part may maintain driving of the compressor until the drying operation ends or drying of the laundry is completed.

[0047] The control unit may drive the first heater or the second heater together with the driving of the compressor so as to increase the temperature inside the inner casing to a set temperature or higher.

[0048] The control unit may interrupt driving of the first heater or the second heater before a constant rate interval in which the rate of increase of the temperature inside the inner casing drops below a reference value ends.

[0049] The control unit may maintain the first heater or the second heater for a set driving time while the internal temperature of the inner casing is equal to or higher than the set temperature.

[0050] The control portion may intermittently and repeatedly drive the first heater or the second heater to prevent the internal temperature of the inner case from rising to a limit temperature higher than the set temperature.

[0051] The control unit may interrupt driving of the first heater or the second heater in a section where a variation range of the internal temperature of the inner casing is below a specific range during driving of the compressor.

[0052] The control unit may block driving of the steam heater before the rate of increase of the inner casing internal temperature becomes higher than a reference value again.

[0053] The control unit may block driving of the steam heater after the internal temperature of the inner casing reaches a drying temperature higher than the target temperature.

[0054] The second heater may be set so that the amount of steam generated by the second heater is smaller than the amount of steam generated by the first heater.

[0055] The steam generation amount generated by the second heater may be set to 50 to 150% of the dehumidification amount of the heat exchanger.

[0056] A movable hanger may also be included, wherein the movable hanger places the clothes inside the inner shell and is driven to shake the clothes.

[0057] The control unit may drive the movable hanger in a section where the internal temperature of the inner case is equal to or higher than the set temperature or when the first heater or the second heater is driven.

[0058] When the temperature inside the inner case is below a set temperature, the control unit may drive the movable hanger at a first frequency or stop driving the movable hanger. When the temperature inside the inner case is above a set temperature, the control unit may drive the movable hanger at a second frequency faster than the first frequency.

[0059] If the control part drives the moving hanger at the second frequency during a reference time, the control part may drive the moving hanger at a third frequency lower than the second frequency.

[0060] If the rate of increase of the inner case internal temperature becomes higher than a reference value or the inner case internal temperature reaches a drying temperature higher than the set temperature, the control part may drive the movable hanger at a third frequency slower than the second frequency.

[0061] The first frequency may be set to be lower than the third frequency.

[0062] When the drying operation is performed, the controller may maintain driving of the compressor until the drying operation ends or the clothes are dried, and drive the movable hanger so that at least a portion of the driving interval overlaps with the driving interval of the steam heater.

[0063] If the moving hanger is driven before the steam heater is driven, the control part may drive the moving hanger faster in the section in which the steam heater is driven.

[0064] If the driving of the moving hanger is blocked before the steam heater is driven, the control part may drive the moving hanger in the section in which the steam heater is driven.

[0065] If the moving hanger is driven during the driving of the steam heater, the control part may not drive the moving hanger or drive the moving hanger slowly after the driving of the steam heater ends.

[0066] In a case where the moving hanger is driven during the driving of the steam heater, if the driving of the steam heater is finished, the control part may maintain the driving speed of the moving hanger for a prescribed time.

[0067] The control unit may drive the steam heater while driving the compressor.

[0068] The control part may set a driving frequency of the moving hanger differently according to an internal temperature of the inner case.

[0069] The control part may drive the moving hanger at a first frequency until the internal temperature of the inner case reaches a set temperature, and may drive the moving hanger at a second frequency faster than the first frequency after the internal temperature of the inner case reaches the set temperature.

[0070] The control unit may drive the movable hanger at a third frequency lower than the second frequency in a period after the internal temperature of the inner case reaches a drying temperature higher than the set temperature.

[0071] The control unit may drive the moving hanger at the second frequency for a set time and then drive the moving hanger at a third frequency lower than the second frequency.

[0072] The second frequency may be set to the fastest frequency for driving the mobile hanger during execution of the program.

[0073] The control unit may drive the steam supply unit to increase the internal temperature of the inner casing to above the set temperature.

[0074] The control unit may drive the movable hanger at the second frequency so that at least a portion of a driving interval overlaps with a driving interval of the steam supply unit.

[0075] The control part may drive the moving hanger at the second frequency after driving the steam supply part.

[0076] When the drying operation is performed, the control unit may maintain driving of the compressor until the drying operation ends or the drying of the clothes is completed, and may control the steam heater so that steam is supplied to the inside of the inner case during driving of the compressor.

[0077] The control unit may first drive the steam heater and then drive the compressor.

[0078] The control unit may first drive the first heater and the second heater, and then simultaneously drive the compressor and the first heater or the second heater.

[0079] Even after the driving of the first heater or the second heater is terminated, the driving of the compressor may be maintained.

[0111] Figure 3 1 is a diagram showing the appearance of the clothes treating apparatus 1 according to the present invention.

[0112] Reference Figure 3 (a) The clothes treating apparatus of the present invention may include: a housing 100 forming an exterior; and a door 400 rotatably coupled to the housing 100 .

[0113] The door 400 may include a main body 410 forming the front of the housing 100 , and a setting body 420 extending from one side of the main body 410 , and a display for displaying information of the laundry treating apparatus may be provided on the setting body 420 .

[0114] The setting body 420 may be configured to form a step 430 from the main body 410 toward the rear of the box body 100 .

[0115] On the other hand, at least a portion of the setting body 420 may be configured to overlap with the main body 410 along the front-to-back direction at the rear of the main body 410. Thus, the step 430 may function as a handle.

[0116] The setting body 420 may be made of a material or color different from that of the main body 410. In addition, the setting body 420 may be made of a translucent material through which light emitted from the display can pass.

[0117] Reference Figure 3 (b), an inner shell 200 may be provided inside the box 100, and the inner shell 200 has a storage space 220 for storing clothes. An opening 210 may be provided in front of the inner shell 200, through which clothes are put in and out, and the opening 210 may be shielded by the door 400.

[0118] The inner housing 200 may be made of a plastic resin or a reinforced plastic resin that is not deformed by air having a temperature higher than normal temperature or heated air (hereinafter referred to as hot air), steam, or moisture.

[0119] The inner housing 200 may be configured to have a height greater than a width, so that the clothes can be accommodated in the accommodation space 220 in an undone or unwrinkled state.

[0120] The clothes treating apparatus 1 of the present invention may include a hanger portion 1000 capable of placing clothes in the accommodation space 220 of the inner housing 200 .

[0121] The hanger 1000 may be disposed on an upper portion of the inner surface of the inner housing 200 and configured to allow the clothes to be placed in a state of hanging down or unfolding from the upper portion to the lower portion.

[0122] Thus, the clothes will not be wrinkled and can be placed inside the inner shell 200.

[0123] In addition, the hanger portion 1000 may be configured to hold a plurality of clothes. The hanger portion 1000 may hold a plurality of clothes spaced apart along the width direction of the inner case 200.

[0124] Thus, even if a plurality of clothes are accommodated in the inner housing 200, they will not contact or interfere with each other. As a result, not only will the plurality of clothes not be damaged, but the entire clothes can be evenly exposed to hot air and steam.

[0125] That is, the hanger portion 100 may be configured as a simple placement portion placed on the upper portion of the inner shell 200 , and configured to fix the clothes in a state of being suspended inside the accommodating space 220 .

[0126] Alternatively, the hanger portion 1000 may be configured as a mobile hanger 1000 that is placed on the upper surface of the inner housing 200 and swings the clothes.

[0127] The movable hanger 1000 may be configured to reciprocate or rotate on the upper portion of the inner housing 200. Thus, foreign matter and the like can be removed as the clothes placed on the movable hanger 100 are shaken in the receiving space 220, and the clothes can be effectively exposed to the supplied steam or hot air.

[0128] The detailed structure and function of the movable clothes hanger 1000 will be described later.

[0129] A pressurizing portion 520 for pressurizing the laundry may be provided on an inner surface of the door 400 .

[0130] The pressurizing portion 520 may include a supporting portion 522 fixed to the inner surface of the door 400 and supporting one side of the clothes; and a pressing portion 521 pressurizing the clothes supported by the supporting portion 522 .

[0131] The pressing portion 521 may be configured to move toward or away from the supporting portion 522. For example, the pressing portion 521 may be rotatably disposed on the supporting portion 522 or the inner surface of the door 400.

[0132] Thus, the pressing portion 521 and the supporting portion 522 can remove creases of the clothing by applying pressure to both sides of the clothing, and can also form desired creases.

[0133] The clothes treating apparatus of the present invention may include a machine room 300 , in which various devices may be provided that can supply one or more of hot air and steam to the accommodating space 220 or can absorb the external air of the housing 100 and discharge it after purification or dehumidification.

[0134] A control unit capable of controlling the laundry processing device may be built into the machine room 300 . Of course, the control unit may also be disposed inside the door 400 .

[0135] The control unit may be provided by a PCB that controls one or more electrical components of the laundry treating apparatus of the present invention to execute any program for treating the laundry.

[0136] The machine chamber 300 may be configured to be separated or partitioned from the inner housing 200 and provided to communicate with the inner housing 200 .

[0137] The machine room 300 may be disposed at a lower portion of the inner case 200. Thus, if hot air and steam having a low specific gravity are supplied to the inner case 200, the hot air and steam may be naturally supplied to the clothes.

[0138] The machine room 300 may include a heating unit 340 capable of supplying hot air to the interior of the inner casing 200. The heating unit 340 may be configured as a heat pump system or as a heater that directly utilizes electrical energy to heat air.

[0139] When the heat supply unit 340 is configured as a heat pump system, the air exhausted from the inner casing 200 can be dehumidified and heated again, and then supplied to the inner casing 200. The detailed structure will be described later.

[0140] The machine room 300 may include a steam supply unit 800 capable of supplying steam to the interior of the inner housing 200. The steam supply unit 800 may be configured to directly supply steam to the interior of the inner housing 200. The detailed structure will be described later.

[0141] To this end, the inner housing 200 may be provided with a plurality of through holes 230 , and the plurality of through holes 230 penetrates one side of the inner housing 200 and communicates with the machinery chamber 300 .

[0142] The air in the accommodation space 220 may be supplied to the machine room 300 through the through hole 230 , and one or more of hot air and steam generated in the machine room 300 may be supplied to the accommodation space 200 .

[0143] The through hole 230 may include: an inlet hole 231, which passes through the lower surface of the inner shell 200, so that the air inside the inner shell 200 flows into the mechanical chamber 300; and an outlet hole 232, which is separated from the inlet hole 231 and passes through the lower surface of the inner shell 200, so that the hot air generated in the mechanical chamber 300 is discharged into the inner shell 200.

[0144] The exhaust hole 232 may be disposed closer to the rear side than the front side or the door 400 in the lower side of the inner case 200 .

[0145] In addition, the exhaust hole 232 may be arranged between the lower surface and the back surface of the inner case 200 to be inclined relative to the ground. The exhaust hole 232 may be provided toward the movable hanger 1000 to guide the hot air to be supplied toward the clothes.

[0146] The inflow hole 231 may be disposed closer to the front or door 400 than to the rear in the lower surface of the inner case 200 .

[0147] The inflow hole 231 may be spaced apart from the discharge hole 232 as much as possible, thereby preventing the air discharged from the discharge hole 232 from not reaching the clothes and being directly absorbed into the inflow hole 231 .

[0148] The through hole 230 may further include a steam hole 233 that penetrates the lower portion of the inner case 200 and guides the steam generated in the steam supply part 800 into the inner case 200 .

[0149] The steam hole 233 may be disposed closer to the discharge hole 232 than the inflow hole 231. For example, the steam hole 233 may be disposed on one side of the discharge hole 232.

[0150] On the other hand, the machine room 300 may further include a water supply tub 30 capable of supplying water to the steam supply part 800 , and a water drain tub 40 for collecting condensed water condensed in the heat supply part 340 .

[0151] The water supply tub 30 and the drainage tub 40 may be installed so as to be detachable from the front of the machine room 300. Thus, the laundry processing apparatus 1 of the present invention may be freely installed without being restricted by a water supply source or a drainage source.

[0152] On the other hand, the machine room 300 may further include a drawer 50, which is introduced into and out of the machine room 300 at the front and has an additional storage space. For example, the drawer 50 may store a steam generator or an iron.

[0153] Figure 4 1 is a diagram showing the structure of a machine room of a clothes treating apparatus according to the present invention.

[0154] Figure 4 (a) is a view of the machine room 300 viewed from the front. Figure 4 (b) is a view of the machine room 300 as viewed from the rear.

[0155] The machine room 300 may include a structure for supplying hot air to the clothes processing space, circulating the air in the clothes processing space, supplying steam to the clothes processing space, or purifying the air outside the cabinet.

[0156] The machine room 300 may include a base portion 310 , which supports various devices or provides a space for installing various devices. The base portion 310 may provide an area for installing various devices.

[0157] The base portion 310 may be provided with a circulation duct 320 through which air flowing in from the inner case 200 or the outside of the housing 100 moves.

[0158] The circulation duct 320 may be provided in a shell shape with an open top surface, and a portion of the heat supply unit 340 may be provided inside the circulation duct 320 .

[0159] When the heating unit 340 is configured as a heat pump system, the heating unit 340 may include heat exchangers 341 and 343 described later within the circulation pipe 320 and a compressor 342 for supplying high-temperature and high-pressure refrigerant to the heat exchangers.

[0160] The heat exchangers 341 and 343 may be accommodated in the circulation duct 320 and dehumidify the air by cooling the air flowing through the circulation duct 320 , or may generate hot air by heating the air.

[0161] In the case where the circulation duct 320 is configured to draw air from outside the housing 100 , an external air duct 370 for drawing external air may be provided in front of the circulation duct 320 .

[0162] The circulation duct 320 may be arranged to communicate with the external gas duct 370 and selectively draw in external air.

[0163] The water supply tank and the drain tank may be detachably coupled to the front of the circulation pipe 320. The water supply tank 30 and the drain tank 40 may be positioned and arranged on the upper portion of the external gas pipe 370.

[0164] The circulation duct 320 may be combined with the base portion 310, or may be integrally provided with the base portion 310. For example, the base portion 310 and the circulation duct 320 may be manufactured by injection molding.

[0165] The machine room 300 may include a base cover 360 configured to communicate with the circulation pipe 320 and the inflow hole 231 .

[0166] The base cover 360 may be combined with an upper portion of the circulation duct 320 and guide the air drawn in through the inflow hole 231 into the inside of the circulation duct 320 .

[0167] The base cover 360 can block the air inside the circulation duct 320 from being discharged to the outside by shielding the upper surface of the circulation duct 320. The lower portion of the base cover 360 and the upper surface of the circulation duct 320 can form one side of the flow path of the circulation duct 320.

[0168] The base cover 360 may include an inflow portion 362 connecting the inflow hole 231 and the circulation duct 320 . The inflow portion 362 may be provided in a duct shape and function as an air intake duct for transferring air inside the inner case 200 to the circulation duct 320 .

[0169] The machine room 300 may be provided with a steam supply unit 800 that receives water by connecting to the water supply tub 30 and generates steam to supply the steam to the inner housing 200. The steam supply unit 800 may be installed and disposed on an upper portion of the base cover 360.

[0170] The steam supply unit 800 may be disposed outside the circulation duct 320. Thus, the steam supply unit 800 may be prevented from hindering movement of air flowing through the circulation duct 320 or heating the air.

[0171] In addition, the steam supply part 800 may be disposed apart from the inflow part 362. For example, the steam supply part 800 may be disposed at a position further rearward than the inflow part 362.

[0172] The machine room 300 may include a fan installation portion 350 configured to connect the circulation duct 320 and the inner housing 200. The fan installation portion 350 may include: an air supply fan 353 for providing power to move air in the circulation duct 320 in one direction; and a fan cover 351 for accommodating the air supply fan 353 and being coupled to or extending from the circulation duct 320.

[0173] The fan installation portion 350 may be provided with an exhaust duct 352 , and the exhaust duct 352 is provided to communicate with the circulation duct 320 and the exhaust hole 232 .

[0174] The exhaust duct 352 may be provided to extend from the fan cover 351 toward the exhaust hole 232 with a cross section corresponding to an area of ​​the exhaust hole 232 .

[0175] As a result, air inside the inner case 200 may flow in through the base cover 360 , pass through the circulation duct 320 , and then be supplied back into the inner case 200 through the fan installation portion 350 .

[0176] Meanwhile, the base portion 310 may be provided with a compressor installation portion 313 , and the compressor 342 that supplies refrigerant to the heat exchangers 341 and 343 may be installed in the compressor installation portion 313 . The compressor installation portion 313 may be disposed outside the circulation pipe 320 .

[0177] In addition, the base portion 310 may be provided with the control portion 700 for controlling the laundry treating apparatus of the present invention.

[0178] The base portion 310 may be provided with a control unit installation portion 312 . The control unit installation portion 312 forms a space at a lower portion of the circulation duct 320 into which the control unit 700 can be inserted.

[0179] The control unit 700 may be configured to control all electronically controllable electrical components, such as the compressor 342 , the steam supply unit 800 , the air supply fan 353 , and the like.

[0180] Since the control unit 700 is inserted into and supported by the base 310 , the vibration generated by the movable hanger 1000 or the clothes can be blocked from being transmitted to the control unit 700 , or the vibration can be transmitted to the control unit 700 after being attenuated.

[0181] Furthermore, since the controller 700 is installed on the base 310 , it is possible to prevent noise or control errors caused by the close distance to all the electrical components installed in the machine room 300 .

[0182] In the laundry processing apparatus of the present invention, the steam supply unit 800 is disposed above the circulation duct 320, and the control unit 700 is disposed below the circulation duct 320. Thus, the circulation duct 320 can be provided in a straight duct shape between the steam supply unit 800 and the control unit 700. As a result, the flow resistance of air passing through the circulation duct 320 can be minimized.

[0183] Since the circulation pipe 320, the external gas pipe 370, the steam supply unit 800, the control unit 700, and the heating unit 340 can all be installed on the base 310, the base 310 can be configured as a module. As a result, most electrical components can be easily installed, maintained, and repaired by allowing the base 310 to be introduced into or removed from the machine room 300 from the front or rear.

[0184] Figure 5 1 is a diagram showing the base structure of a machine chamber of a clothes treating apparatus according to the present invention.

[0185] Figure 5 (a) is a perspective view of the base portion 310 viewed from the front. Figure 5 (b) and Figure 5 (c) is a three-dimensional view of the base portion 310 as viewed from the rear.

[0186] The base portion 310 may be disposed on a base plate forming the lower surface of the laundry processing apparatus, or the base portion 310 itself may form the lower surface of the laundry processing apparatus.

[0187] The base portion 310 may include a base bottom 311 forming a support surface. The base bottom 311 may form the lower surface of the laundry treatment device. In addition, the base bottom 311 may be provided on the upper surface of the bottom surface of the housing 100 forming the lower surface of the laundry treatment device.

[0188] The base portion 310 may be integrally provided with the circulation duct 320 , and the circulation duct 320 may form at least a portion of a flow path for air movement. The circulation duct 320 may be formed by extending upward from the base bottom portion 311 .

[0189] The circulation duct 320 may include: a duct body 321 extending from the bottom 311 of the base to form a flow path; a heat exchanger setting portion 3212 providing a space inside the duct body 321 for setting an evaporator 341 or a condenser 343; and an air exhaust portion 323 provided at the rear of the duct body 321 to exhaust air from the duct body 321.

[0190] The air discharge portion 323 may be provided in a tube shape extending rearward from the duct body 321. A diameter of the air discharge portion 323 may be smaller than a width of the duct body 321.

[0191] The air discharge portion 323 may be connected to the fan cover 350 . The air discharged from the air discharge portion 323 may be guided into the inner housing 200 through the fan cover 350 .

[0192] The circulation duct 320 may include an external air suction portion 322 formed through a front surface of the duct body 321 .

[0193] The external air intake portion 322 may be provided to communicate with the external air pipe 370 . The external air pipe 370 may be positioned and supported in front of the external air intake portion 322 .

[0194] The circulation duct 320 may be provided with a damper for opening and closing the external air suction portion 322. By opening and closing the damper, the external air may be allowed or blocked to flow into the circulation duct 320.

[0195] The base portion 310 may include a compressor installation portion 312, which provides a space for installing the compressor 342. The compressor installation portion 312 may be formed on one side of the base bottom 311 and integrally formed with the base bottom 311.

[0196] The compressor mounting portion 312 may also be formed with a protrusion capable of supporting the compressor 342. The compressor mounting portion 312 may be disposed at a position offset to the rear of the base portion 310. The compressor mounting portion 312 may be disposed so that at least a portion overlaps with the air discharge portion 323 in the width direction.

[0197] The compressor installation portion 312 may be provided with a buffer member to reduce vibration transmitted from the compressor 342. The buffer member may be fixed to the protrusion.

[0198] The base 310 may include a control unit installation portion 313 for installing the control unit 700. The control unit installation portion 313 may be formed between the base bottom 311 and the circulation duct 320. The control unit installation portion 313 may be installed between the base bottom 311 and the bottom surface of the circulation duct 320. The control unit installation portion 313 may be installed in the shape of a duct at the bottom of the circulation duct 320, with either the front or rear side open.

[0199] Figure 6 1 is a diagram showing a circulation duct structure of a clothes treating apparatus according to the present invention.

[0200] The circulation duct 320 may extend from the bottom of the base to the top to form a flow path for air flow. The circulation duct 320 may include a heat exchanger installation portion 3212, which provides a space for installing the evaporator 341 and the condenser 342. The heat exchanger installation portion 3212 may be installed inside the duct body 321.

[0201] The duct body 321 may be provided with an open top surface, and the condenser 343 and the evaporator 341 may be inserted and installed through the opening of the duct body 321 .

[0202] The opening of the duct body 321 may be shielded by the base cover 360 , and the base cover 360 and the duct body 321 may form a flow path of the circulation flow path 320 .

[0203] The front surface of the duct body 321 may be spaced apart from the front end of the base bottom 311 toward the rear.

[0204] Thus, the base bottom 311 can ensure a support surface 3111 for installing and supporting at least one of the water supply bucket 30 , the drainage bucket 40 and the external gas pipe 370 .

[0205] On the other hand, the heating part 340 may include: an evaporator 341, which is arranged inside the circulation pipe 320 and is configured as a heat exchanger for dehumidifying by cooling the air flowing into the circulation pipe 320; a condenser 343, which is configured as a heat exchanger for forming hot air by heating the air passing through the evaporator 341; a compressor 342, which supplies a refrigerant for heat exchange with the air to the condenser 343 and is configured outside the circulation pipe 320; and an expansion valve 344, which cools by expanding the refrigerant passing through the condenser 343.

[0206] Furthermore, since the duct body 321 is integrally formed with the base portion 310, the height of the heat exchanger mounting portion 3212 can be increased, and the heights of the condenser 343 and evaporator 341 can be increased. As a result, the widths of the condenser 343 and evaporator 341 in the front-to-back direction can be shortened, thereby reducing the number of refrigerant pipes passing through the condenser and evaporator. This effectively reduces air flow losses through the condenser and evaporator.

[0207] On the other hand, the sum of the lengths of the evaporator 341 and the condenser 343 may be shorter than the length of the heat exchanger installation portion 3212 .

[0208] Therefore, the heat exchanger installation portion 3212 can be sufficiently separated from the external air suction portion 322 , thereby ensuring a sufficient space in the circulation duct 320 for the external air and the air in the inner casing 200 to flow in.

[0209] On the other hand, the interior of the duct body 321 may include a partition wall 3211 that divides the heat exchanger installation portion 3212 from the outside of the heat exchanger installation portion 3212. The partition wall 3211 may protrude from a side of the duct body 321 and support the front of the evaporator 341.

[0210] In addition, the duct body 321 may be expanded with the partition wall 3211 as a reference width and extend rearward.

[0211] As a result, the width of the heat exchanger installation portion 3212 can be set to be larger than half the width of the base portion 310. In addition, the width of the circulation duct 320 can be set to be larger than half the width of the base portion 310.

[0212] The width of the condenser 343 and the width of the evaporator 341 may also be set to be larger than half of the entire width of the base portion 310. As described above, if the widths of the condenser 343 and the evaporator 341 are ensured, the heat exchange capacity can be sufficiently ensured.

[0213] In addition, the fan cover 350 can be configured to overlap with the condenser 343 or the evaporator 341 in the front-to-back direction. As a result, the air that has passed through the evaporator 341 and the condenser 343 can flow into the fan cover 350 without any bends in the flow path. That is, the air that flows into the circulation duct 320 does not have any bends in the flow path during the process of moving to the fan cover, thereby having the effect of minimizing flow losses. The clothing processing device of the present invention may further include: a temperature sensor S1 for sensing the temperature inside the inner shell 200 or the temperature of the air flowing from the inside of the inner shell 200 into the circulation duct 320; and a refrigerant sensor S2 for sensing the temperature of the refrigerant circulating in the heating unit.

[0214] The temperature sensor S1 may be installed on the inner wall of the circulation pipe 320 , and the refrigerant sensor S2 may be installed on the discharge side of the compressor 342 .

[0215] Figure 7 FIG. 1 is a diagram showing the structure of the air exhaust portion 323 of the clothes treating apparatus according to the present invention.

[0216] The base portion 310 may include an air discharge portion 323 for discharging processed air toward the fan housing.

[0217] The air outlet portion 323 may be configured to communicate with the interior of the circulation duct 320 or the duct body 321 and the fan cover 350. The air outlet portion 323 may be configured in a bell mouth shape. By configuring in a bell mouth shape, air flow loss can be reduced and air circulation efficiency can be improved.

[0218] The air exhaust pipe 3232 of the air exhaust portion 323 can be set in a tube shape. During the demolding process based on the parting line 3233, the mold arranged in front of the parting line 3233 can be led out forward, and the mold arranged behind the parting line 3233 can be led out from the rear.

[0219] The fan installation portion 350 may be supported by being coupled to the air outlet pipe 3232. The fan cover 351 may have a coupling hole coupled to the outer peripheral surface of the air outlet pipe 3232, and the air supply fan 353 may be disposed in the coupling hole.

[0220] The fan cover 351 may include an exhaust duct 352 , and the exhaust duct 352 extends from an outer circumference or outer side of the air supply fan 353 toward the exhaust hole 232 .

[0221] The fan cover 351 and the exhaust duct 352 may house the air supply fan 353 and form a flow path for air movement.

[0222] A motor for rotating the air supply fan 353 may be coupled to and supported by the exterior of the fan cover 351 .

[0223] Figure 8 1 is a diagram showing the structure of a base cover of a clothes treating apparatus according to the present invention.

[0224] The base cover 360 may be coupled to an upper surface of the circulation duct 320 and provided to prevent the inside of the circulation duct 320 from being exposed.

[0225] The base cover 360 may include an inflow body 361 coupled to an upper surface of the circulation duct 320 to connect the inner shell 200 and the circulation duct 320 ; and a shielding body 363 extending from the inflow body 361 to shield the circulation duct 320 .

[0226] The inflow body 361 may be in the shape of a pipe and is provided to communicate with the inflow hole 231 of the inner shell and the inside of the circulation pipe 320. The inflow body 361 may be more protruding upward than the shielding body 363.

[0227] The inflow body 361 may be disposed forward of the evaporator 341 so as not to face the evaporator 341 and the condenser 343 , and may be disposed forward of the partition wall 3211 .

[0228] The inflow body 361 may function as an inflow duct for moving the air in the inner casing 200 toward the circulation duct 320 .

[0229] An inlet portion 362 through which air of the inner housing 200 can pass may be provided inside the inlet body 361 .

[0230] Specifically, the base cover 360 may include: a first rib 362 a extending along the width direction of the inflow body 361 ; and a second rib 362 b spaced rearward from the first rib 362 a and extending along the width direction of the inflow body 361 .

[0231] The first rib 362a and the second rib 362b may be arranged in parallel. The first rib 362a and the second rib 362b may be arranged in a plate shape extending in a vertical direction, and the height thereof may correspond to the height of the inflow body 361 .

[0232] The front edge of the inflow body 361 and the first rib 362a may form a first inflow port 3621 , the first rib 362a and the second rib 362b may form a second inflow port 3622 , and the second rib 362b and the rear edge of the inflow body 361 may form a third inflow port 3623 .

[0233] The area of ​​the first inlet 3621 and the area of ​​the third inlet 3622 may be the same as each other, and the area of ​​the second inlet 36222 may be smaller than the areas of the first inlet 3621 and the third inlet 3622 .

[0234] The base cover 360 may include a damper portion 364 configured to open and close the inlet portion 362 ; and a driving portion 365 coupled to the damper portion 364 to control the opening and closing of the damper portion 364 .

[0235] The damper portion 364 may include a first damper portion 3641 configured to open and close the first inlet 3621 ; and a second damper portion 3642 configured to open and close the third inlet 3623 .

[0236] The first damper portion 3641 may be provided in a plate shape having an area corresponding to the first inlet 3621 , and may be rotatably coupled to both side surfaces of the inlet body 361 within the first inlet 3621 .

[0237] The second damper portion 3642 may be provided in a plate shape having an area corresponding to the third inlet 3622 , and may be rotatably provided on both side surfaces of the inlet body 361 inside the third inlet 3622 .

[0238] The second inlet 3622 may be provided with a blocking filter 366 . The blocking filter 366 allows air to pass through but can filter foreign matter such as dust and fluff.

[0239] The blocking filter 366 may be inserted into the second inlet 3622 to separate the first inlet 3621 from the third inlet 3623 . The blocking filter 366 may extend to the second inlet 3622 to contact the bottom surface of the circulation duct 320 .

[0240] The blocking filter 366 may be provided as a filter capable of filtering even the moisture. For example, the blocking filter 366 may be provided as a high efficiency particulate air filter or the like.

[0241] On the other hand, the second inlet 3622 may be further combined with a shielding member. If the blocking filter 366 is inserted, the shielding member shields the second inlet 3622 .

[0242] The driving portion 365 may include a motor that provides power to selectively rotate the first damper portion 364 and the second damper portion 365 ; and a plurality of gear members that engage with and rotate with the motor to selectively rotate the first damper portion 364 and the second damper portion 365 .

[0243] The first inlet 3611 and the third inlet 3623 may be selectively opened by the driving unit 365 .

[0244] The air contained in the inner shell 200 may flow into the circulation duct 320 through the first inlet 3621 or the third inlet 3623 through the driving unit 365 .

[0245] Of course, the driving unit 365 can control the first damper 3641 and the second damper 3642 to fully open the first inlet 3611 and the third inlet 3623 , and can control the first damper 3641 and the second damper 3642 to fully cover the first inlet 3611 and the third inlet 3623 .

[0246] The driving unit 365 may be configured in any structure as long as it can rotate the first damper 3641 and the second damper 3642. For example, it may be configured in a combination of a motor, a driving gear rotated by the motor, and a driven gear coupled to the first damper and the second damper and rotated by the rotation of the driving gear.

[0247] The base cover 360 may include a shielding body 363 extending from the inflow body 361 and capable of shielding the evaporator 341 and the condenser 343. The shielding body 363 may have a plate shape.

[0248] The base cover 360 may be detachably coupled to the upper surface of the circulation duct 320 using an inflow hook 3612 extending from the lower surface of the inflow body 361 .

[0249] The circulation pipe 320 may be provided with a coupling portion detachably coupled to the inflow hook 3612 .

[0250] Figure 9 It is a diagram showing the installation structure of the steam supply unit.

[0251] The steam supply part 800 may be seated and supported on the base cover 360 .

[0252] The steam supply part 800 may include a steam generator 810 installed at the base cover 360 and storing water for generating the steam.

[0253] The steam supply unit 800 may further include a mounting bracket 870 , and the mounting bracket 870 may be configured to fix the steam generator 810 to the base cover 360 .

[0254] The mounting bracket 870 may be combined with the base cover 360 and fix the steam generator 810 .

[0255] The mounting bracket 870 may include a lower panel 871 for supporting the lower surface of the steam generator 810 , and side panels 872 for supporting both side surfaces of the steam generator 810 on the lower panel 871 .

[0256] The mounting bracket 870 may further include one or more fixing clips 873 , which extend from the side panel 872 and prevent the steam generator 810 from being detached.

[0257] The fixing clip 873 may be detachably mounted on the upper portion or side of the steam generator 810 .

[0258] The compressor 342 may be disposed below the steam supply unit 800 .

[0259] The bracket 870 may be provided to block heat generated in the compressor or heat generated by the refrigerant compressed in the compressor from being transferred to the steam supply part 800 .

[0260] The bracket 870 may also prevent the fire from spreading to the steam supply unit 800 when a fire occurs in the compressor 342 .

[0261] On the other hand, the base cover 360 may include a fastening portion 3631 provided on the shielding body 363 and detachably coupled to the steam supply unit 800. The fastening portion 3631 may be detachably coupled to a protrusion protruding from the lower portion of the steam generator 810.

[0262] Thus, even if a large amount of water is contained in the steam generator 810 , the steam generator 810 can be stably placed on the base cover 360 .

[0263] In addition, since the steam generator 810 is arranged at an upper position than the circulation pipe 320 and is closer to the inner shell 200 , condensation of the steam generated by the steam generator 810 before reaching the inner shell 200 can be minimized.

[0264] Figure 10 1 is a diagram showing a detailed structure of the steam supply unit.

[0265] Reference Figure 10 (a), the steam supply unit 800 may include: a steam generator 810 capable of receiving and storing water for generating steam; and a steam heater 840 accommodated in the steam generator 810, generating steam by heating the water.

[0266] The steam generator 810 may be provided in a housing shape forming a space for accommodating the steam heater 840 .

[0267] For example, the steam generator 810 may be provided in the form of a shell with an upper portion opened, and may be provided to accommodate the steam heater 840 .

[0268] The steam supply unit 800 may further include a housing cover 820 . The housing cover 820 is combined with the steam housing 810 to prevent the steam heater 840 from being exposed to the outside and the water from flowing out.

[0269] The housing cover 820 may be provided with: a water level sensor 850 for sensing the water level of the steam generator 810 ; and a steam sensor 860 for sensing the temperature inside the steam generator 810 or sensing whether steam is generated inside the steam generator 810 .

[0270] Reference Figure 10 (b), the steam generator 810 may include a housing body 811 providing a space for storing the water and accommodating the steam heater 840 .

[0271] The housing body 811 may be provided in a shape with an upper opening, so that various components can be easily provided inside the housing body 811 .

[0272] The housing body 811 may include a heater insertion hole 8111 that passes through one side of the housing body 811 , and the steam heater 840 may be inserted into or drawn out of the housing body 811 through the heater insertion hole 8111 .

[0273] A recovery pipe 814 for receiving water for generating steam may be provided inside the housing body 811 .

[0274] The recovery pipe 814 may also be configured to discharge the water contained in the shell body 811 to the outside.

[0275] The recovery pipe 814 can remain blocked by the shielding cover 8141 so as to be opened only when the residual water inside the steam shell 810 is removed, and can include a shielding clamp 8142, which keeps the shielding cover 8141 coupled to the recovery pipe 814 to prevent the shielding cover 8141 from being separated at will.

[0276] Therefore, when repairing the steam generator 800 or preventing the steam generator 800 from freezing and cracking, the water inside the steam generator 800 can be discharged through the recovery pipe 814.

[0277] Of course, the recovery pipe 814 can be configured to receive water from the water supply tank 30. The details will be described later.

[0278] On the other hand, a heater fixing portion 830 capable of supporting or fixing the steam heater 840 may be provided inside the housing body 811. The heater fixing portion 830 may include a fixing clamp 831 for fixing the steam heater 840 and a clamping member 833 for fixing the supporting clamp 831 to the housing body 811.

[0279] The fixing clip 831 may be configured to accommodate or surround at least a portion of the steam heater 840 .

[0280] On the other hand, the steam supply unit 800 may be provided with a water supply pipe 815 for receiving water. The water supply pipe 815 may receive water by being communicated with the water supply tub 30.

[0281] The water supply pipe 815 may be provided on the housing cover 820 or disposed on the upper portion of the steam generator 810. Thus, water can be prevented from flowing back through the water supply pipe 815.

[0282] The steam supply unit 800 may be provided with a steam pipe 813 for discharging steam generated by the steam heater 840 to the outside. The steam pipe 813 may also be provided on the upper portion of the housing cover 820 to prevent water from being discharged from the steam pipe 813.

[0283] The steam pipe 813 may be in communication with the steam hole 233 of the inner shell 200 .

[0284] The housing cover 820 may be provided with a water level sensor hole 854 , and the water level sensor may be provided in the water level sensor hole 854 .

[0285] The water level sensor 850 may include: one or more contact protrusions 852, which are inserted into the water level sensor hole 854 and sense the water level by being immersed in water; and a sensor body 851, which is combined with the water level sensor hole 854 or supported on the shell cover 820 in order to keep the contact protrusion 852 in a floating state inside the steam generator 810.

[0286] The sensor body 851 may be coupled to the housing cover 820 using a sensor fastening member 853 .

[0287] On the other hand, the housing cover 820 may be provided with an insertion hole 864, and the steam sensor 860 may be provided in the insertion hole 864. The steam sensor 860 may include: a sensing device 861 inserted into the insertion hole 864 to sense whether steam is generated inside the steam generator 810; a support 863 to fix the sensing device 861 to the housing cover 820; and a coupling member 862 to couple the support 863 to the housing cover 820.

[0288] The sensing device 861 may be configured as a humidity sensor or a temperature sensor, and senses whether steam is generated inside the steam generator 810 .

[0289] On the other hand, the housing cover 820 may be provided with a cover hook 821 , and the cover hook 821 may extend forward and be coupled to the base cover 860 .

[0290] In addition, a fixing protrusion 822 may be further provided at the rear of the housing cover 820 , and the fixing protrusion 822 may fix the lower portion of the inner housing 200 or the additional steam exhaust portion 900 .

[0291] The steam heater 840 may be configured to be inserted into the heater insertion hole 8111 and accommodated in the steam generator 810 , and heat water by receiving power.

[0292] The steam heater 840 may be provided as a jacket heater or the like, and may be controlled by the control unit 700 to be repeatedly driven and stopped.

[0293] The steam heater 840 may include a first heater 841 that heats water by receiving a first power, and a second heater 842 that heats water by receiving a power smaller than the first power.

[0294] As a result, the second heater 842 may be configured to heat less water and generate more steam than the first heater 841 .

[0295] The first heater 841 and the second heater 842 may be configured to share the maximum heater power allowed for the steam heater 840 of the laundry processing apparatus. That is, if the first heater 841 consumes a portion of the maximum heater power, the second heater 842 consumes the remaining portion of the maximum heater power.

[0296] For example, if the maximum heater power allowed for the steam heater 840 is 1500W, the first heater 841 can be set to consume 880W, while the second heater 842 can be set to consume 600W. In this way, 20W can be allocated less to account for errors.

[0297] Of course, the steam heater 840 may include more than three heaters. For example, the steam heater 840 may include the first heater 841, the second heater 842, and the third heater 843, and the first heater 841, the second heater 842, and the third heater 843 may share the maximum heater power consumption.

[0298] The following description will be based on a case where the steam heater 340 includes the first heater 841 and the second heater 842 .

[0299] The first heater 841 and the second heater 842 may be formed of metal pipes in a “U” shape.

[0300] The steam heater 840 may include a heater seal 843 that fixes the first heater 841 and the second heater 842 and seals the heater through hole 8111 , and may include a terminal portion 844 that supplies current to the first heater 841 and the second heater 842 .

[0301] The terminal portion 844 may include a first terminal 844 a for supplying current to the first heater 841 and a second terminal 844 b for supplying current to the second heater 842 .

[0302] The first heater 841 and the second heater 842 may be disposed at the same height. Thus, the first heater 841 and the second heater 842 may be configured to generate steam by heating water at the same water level.

[0303] Thus, the control part 700 can adjust the amount of steam generated and the power consumption by using the first heater 841 and the second heater 842 entirely or selectively.

[0304] Figure 11is a diagram showing the interior of the steam generator.

[0305] The steam generator 810 may include a heating space 817 in which water is stored and a steam heater 840 is accommodated.

[0306] In addition, the steam generator 810 may receive water for generating steam through a water supply hose 8151 connected to the water supply pipe 815 .

[0307] On the other hand, the steam generated in the steam generator 810 by driving the steam heater 840 may be discharged to the outside of the steam supply part 800 through the steam discharge pipe 813 and along the steam hose 8131 .

[0308] The steam hose 8131 may be in communication with the steam hole 233 of the inner shell 200 .

[0309] On the other hand, the steam generator 810 may be provided with a partition wall 812 capable of separating the heating space 817 and the water level sensor 850. That is, the partition wall 812 may be provided to separate the steam heater 840 and the water level sensor 850 and configured to be biased toward one side of the housing body 811.

[0310] The water level sensor 850 may be disposed between the partition wall 812 and the inner surface of the housing body 811 .

[0311] Thus, water vibration generated when the water boils can be prevented from being transmitted to the water level sensor 850 , and heat generated by the steam heater 840 can be prevented from being directly transmitted to the water level sensor 850 .

[0312] Figure 12 FIG. 1 is a diagram showing a steam supply unit provided with the steam heater.

[0313] Reference Figure 12 (a), the steam sensor 860 can be arranged at a position higher than the steam heater 840 and configured to sense the temperature inside the steam generator 810. Thus, when the temperature of the water reaches 100 degrees or higher, the steam sensor 860 can sense that steam is generated.

[0314] The steam heater 840 is supported by the support clip 832 , thereby preventing the steam heater 840 from contacting the bottom surface of the steam generator 810 .

[0315] In addition, the upper portion of the steam heater 840 is surrounded by the fixing clamp 831 , thereby preventing the water level where the steam heater 840 is disposed from changing.

[0316] Reference Figure 12 (b), the heater seal 844 of the steam heater 840 may include: a first support hole 8441, the first heater 841 passes through the first support hole 8441 and is supported; and a second support hole 8442, the second heater 842 passes through the second support hole 8442 and is supported.

[0317] A first length L1 of the first supporting hole 8441 spaced from the bottom surface of the steam generator 810 and a second length L2 of the second supporting hole 8442 spaced from the bottom surface of the steam generator 810 may be the same as each other.

[0318] Even if the diameters of the first support hole 8441 and the second support hole 8442 are different from each other, the setting heights may be the same.

[0319] Thus, the first heater 841 and the second heater 842 can heat water at the same water level to generate steam.

[0320] Figure 13 FIG. 1 is a diagram showing in detail the steam supply structure of the clothes treating apparatus of the present invention.

[0321] The steam generated in the steam generator 810 may be directly supplied to the inside of the inner case 200 through the steam pipe 813 .

[0322] However, if steam is directly supplied to the interior of the inner case 200 through the steam pipe 813 , there is a risk that water contained in the steam generator 810 may also be supplied to the interior of the inner case 200 .

[0323] In addition, there is a risk that the water heated in the steam generator 810 heats the bottom surface of the inner casing 200 , causing the inner casing 200 to be damaged by the heat.

[0324] To this end, the steam supply unit 800 of the present invention may further include a steam nozzle 900 that receives the steam generated in the steam generator 810 and supplies the steam to the inner housing 200 .

[0325] The steam nozzle 900 may be spaced apart from the steam generator 810 and configured to receive only the steam generated in the steam generator 810 but not the water contained in the steam generator 810 .

[0326] For example, the steam nozzle 900 may be disposed above the steam generator 810 and connected to the steam pipe 813. Thus, the steam generated by the steam generator 810 can rise due to a density difference and be supplied to the steam nozzle 900 along the steam pipe 813, while the water contained in the steam generator 810 cannot flow into the steam pipe 813 or the steam nozzle 900 due to gravity.

[0327] The steam nozzle 900 may be disposed between the bottom surface of the inner casing 200 and the steam generator 810 and configured to communicate with the steam hole 233 .

[0328] On the other hand, the steam supply part 800 of the present invention is configured to generate steam by receiving water from the water supply tub 30 .

[0329] To this end, the laundry treating apparatus of the present invention may further include a water supply pump 880 that supplies water contained in the water supply tub 30 to the steam supply part 800 .

[0330] The steam supply unit 800 may further include a supply pipe 890 configured to guide the water contained in the water supply tub 30 to the water supply pump 880 .

[0331] In addition, the laundry processing apparatus of the present invention may further include a water supply pipe 815 for guiding water discharged from the water supply pump 880 to the steam supply unit 800. The water supply pipe 815 may be provided in the form of a rubber water supply hose 8151, for example.

[0332] As a result, the water supply pump 880 may be configured to receive water from the supply pipe 890 connected to the water supply tub 30. In addition, the water supply pump 880 may be configured to discharge water through the water supply pipe 881 to supply water to the steam supply part 800.

[0333] It can be considered that the steam supply unit 800 includes a water supply pump 880 that provides power to supply water contained in the water supply tub 30 to the steam generator 810 .

[0334] The supply pipe 890 may be provided as a hose connecting the water supply barrel 30 and the water supply pump 880 , and the water supply pipe 881 may be provided as a hose combined with the water supply pump 880 .

[0335] On the other hand, the water supply pipe 815 may be provided to directly connect the water supply pump 880 and the steam generator 810. Thus, water supplied from the water supply pump 880 may be directly supplied to the steam generator 810 and heated by the steam heater 840 to generate steam. The steam may be supplied to the steam nozzle 900 through the steam pipe 813 and transferred to the inner casing 200.

[0336] However, if Figure 15 As shown, the water supply pipe 815 can be configured to directly connect the water supply pump 880 and the steam nozzle 900 .

[0337] In other words, the laundry treating apparatus of the present invention may be configured to supply water contained in the water supply tub 30 to the steam nozzle 900 instead of the steam generator 810 . Water supplied from the water supply pump 880 may be directly supplied to the steam nozzle 900 .

[0338] The water supply pump 880 may not be directly connected to the steam generator 810 . Instead, the water supply pump 880 may be connected to the steam generator 810 via the steam nozzle 900 .

[0339] The steam nozzle 900 may receive water contained in the water supply tub 30 using the water supply pump 880. The water supplied to the steam nozzle 900 may be transferred to the steam generator 810.

[0340] Since the steam nozzle 900 is disposed above the steam generator 810 , water supplied to the steam nozzle 900 may be automatically supplied to the steam generator 810 .

[0341] As a result, the steam nozzle 900 may be configured to receive water contained in the water supply tub 30 using the water supply pump 880 and transfer the water to the steam generator 810 .

[0342] The steam supply unit 900 may further include a recovery pipe 815 connecting the steam nozzle 900 and the steam generator 810. The recovery pipe 815 may supply the water temporarily stored in the steam nozzle 900 to the steam generator 810.

[0343] Thus, the steam pipe 813 for allowing steam to flow into the steam nozzle 900 and the recovery pipe 815 for discharging water from the steam nozzle 900 may be provided as separate flow paths.

[0344] Therefore, it is possible to prevent the water supplied from the steam nozzle 900 from interfering with the movement of the steam supplied from the steam generator 810 .

[0345] Alternatively, the recovery pipe 815 may be arranged in a U-shaped configuration. Specifically, the recovery pipe 815 may be configured so that a portion of the area between its two ends is lower than the height of the two ends. As a result, water may accumulate in the recovery pipe 815, acting like a trap, thereby preventing steam or water supplied from the steam generator 810 from flowing back into the recovery pipe 815.

[0346] The steam pipe 813 may include a steam hose 8131 connecting the steam nozzle 900 and the steam generator 810. The steam hose 8131 may be made of rubber.

[0347] The recovery pipe 815 may be provided separately from the steam pipe 813 and spaced apart from the steam pipe 813. A recovery hose 8151 may be included to connect the steam nozzle 900 and the steam generator 810. The recovery hose 8151 may be made of rubber.

[0348] The steam generator 810 may receive and contain water supplied from the steam nozzle 900. Since the steam generator 810 is not directly connected to the water supply pump 880, the water flowing into the steam generator 810 may not flow back to the water supply pump 880.

[0349] Furthermore, the steam nozzle 900 is disposed above the steam generator 810 and is connected to the steam generator 810 via the recovery pipe 815. Therefore, water supplied to the steam nozzle 900 can be automatically supplied to the steam generator 810 by gravity. As a result, the water supplied to the steam nozzle 900 from the water supply pump 880 cannot flow back to the water supply pump 880.

[0350] As a result, the check valve between the water supply pump 800 and the steam nozzle 900 or the steam generator 810 can be omitted. Thus, the water supply pipe 881 can be provided as a water supply hose. This simplifies the flow path for water supply to the steam supply unit 900 and reduces the possibility of water leakage from the flow path.

[0351] Furthermore, the water supply pump 800 can supply water at a very high pressure to the steam nozzle 900. Consequently, foreign matter and bacteria accumulated in the steam nozzle 900 can be washed away by the water supplied to the steam nozzle 900 and supplied to the interior of the steam generator 810. Therefore, the steam nozzle 900 can be kept clean at all times, and the flow of the supplied steam can be prevented from being obstructed.

[0352] On the other hand, if the steam supplied from the steam nozzle 900 is condensed, the condensed water can flow back into the steam generator 810 through the recovery pipe 815. That is, the condensed water generated in the steam nozzle 900 can be recovered to the steam generator 810 in the same direction as the water supplied from the water supply pump 800 and reused as water for generating the steam. Therefore, the laundry treatment apparatus of the present invention can prevent the water level in the water supply tub 30 from dropping rapidly and also prevent water waste.

[0353] Figure 14 Schematic diagram showing the flow path structure of the steam supply unit of the present invention.

[0354] The water supplied from the water supply pump 880 may be supplied to the steam nozzle 900 along the water supply pipe 881 .

[0355] The steam nozzle 900 may supply the received water to the steam generator 810 .

[0356] The steam generator 810 may utilize the recovery pipe 815 to receive water.

[0357] If steam is generated by heating water in the steam generator 810 through the steam heater 840 , the steam may be supplied to the steam nozzle 900 along the steam pipe 813 .

[0358] At this time, the recovery pipe 815 and the steam pipe 813 may be separated from each other and disposed in the steam generator 810 .

[0359] The steam condensed in the steam nozzle 9000 may flow back into the steam generator 810 through the recovery pipe 815 .

[0360] In the steam generator 810, except for the recovery pipe 815 and the steam pipe 813 connected to the steam nozzle 900, the hose connected to the outside can be omitted. In other words, since the water supply pump 880 does not need to be directly connected to the steam generator 810, the hose connecting the water supply pump 800 and the steam generator 810 can be omitted.

[0361] Therefore, in the clothes processing apparatus of the present invention, only the water supply pipe 881, the recovery pipe 815, and the steam pipe 813 are provided as the flow path related to steam, thereby simplifying the flow path structure.

[0362] In addition, the steam nozzle 900 may be disposed above the steam generator 810. Thus, all water supplied to the steam nozzle 900 may be guided to the steam generator 810 without an additional check valve.

[0363] Therefore, if water supplied from the water supply pump 880 is supplied to the steam nozzle 900 , all of the water supplied to the steam nozzle 900 may be guided to the steam generator 810 , thereby eliminating the possibility of water backflowing from the steam nozzle 900 to the water supply pump 880 .

[0364] Therefore, the check valve between the water supply pump 880 and the steam nozzle 900 may be omitted.

[0365] Furthermore, since the check valve is not required on the water supply pipe 880, there is no need to install multiple water supply pipes 880, and a single hose can be used. This not only simplifies the flow path structure, but also simplifies the installation and repair of the flow path, further reducing the possibility of water leakage.

[0366] Figure 15 It is a diagram showing the flow path structure of the steam nozzle.

[0367] The steam nozzle 900 may include a supply container 910 , and the supply container 910 may receive and store steam from the steam housing 810 or water from the water supply pump 880 .

[0368] The supply container 910 may be provided in a housing shape having an inner space capable of receiving and containing water or steam.

[0369] The water supply pipe 881 may be connected to the supply container 910 at a position higher than the bottom surface of the supply container 910. For example, the water supply pipe 881 may be coupled to the side surface of the supply container 910. This prevents the water supplied to the supply container 910 from flowing back into the water supply pipe 881.

[0370] The water supply pipe 881 may be connected to the supply container 910 at a higher position than the recovery pipe 815. For example, the recovery pipe 815 may be configured such that one end is coupled to the bottom surface of the supply container 910 and the other end is coupled to the steam generator 810. Thus, water supplied to the water supply pipe 881 may automatically flow into the recovery pipe 815.

[0371] In addition, the recovery pipe 815 may be provided in a U-shape so as to accommodate a predetermined amount of water inside the recovery pipe 815 .

[0372] On the other hand, the recovery pipe 815 may be disposed adjacent to the water supply pipe 881 , so that the water supplied from the water supply pipe 881 can flow quickly into the steam housing 810 without remaining in the supply container 810 .

[0373] On the other hand, one end of the steam pipe 813 may be coupled to the lower portion of the supply container 910, and the other end may be coupled to the upper end of the steam generator 810 or the steam cover 820. Thus, the steam generated in the steam generator 810 may be automatically supplied to the supply container 910 by density difference.

[0374] The steam pipe 813 may be connected to a position above the supply container 910 relative to the recovery pipe 815. In addition, the steam pipe 813 may be disposed farther from the water supply pipe 881 than the recovery pipe 815.

[0375] Thus, the water supplied to the supply container 910 can be supplied more toward the recovery pipe 815 without flowing back from the steam pipe 813 .

[0376] The steam pipe 813 may be combined with a bottom surface of the supply container 910 .

[0377] The bottom surface of the supply container 910 may be arranged such that the position where it is combined with the recovery pipe 815 is low, and the portion where it is combined with the steam pipe 813 is higher. To this end, the bottom surface of the supply container 910 may be formed with a step or inclined setting.

[0378] The steam nozzle 900 may further include a container cover 920 coupled to an upper portion of the supply container 910. The container cover 920 may include a steam injection hole 923 formed through an upper portion of the container cover 920. The steam injection hole 923 may be provided to communicate with the interior of the inner case 200.

[0379] The supply container 910 may be provided in the form of a box with an upper portion opened, and the container cover 920 may be provided to cover the upper portion of the supply container 910 .

[0380] The steam supplied through the steam pipe 813 may be discharged through the steam injection hole 923 and supplied to the inside of the inner case 200 .

[0381] The steam pipe 813 can be disposed between the steam injection hole 932 and the inner side surface of the supply container 910. The steam injection hole 932 can be disposed between the water supply pipe 881 and the steam pipe 813, and can be disposed between the recovery pipe 815 and the steam pipe 813. Thus, steam that is not discharged from the steam injection hole 932 and is condensed can be discharged from the recovery pipe 815 without remaining inside the supply container 910.

[0382] The steam injection hole 932 may be disposed at the center of the container cover 920 based on the width direction of the container cover 920 .

[0383] The container cover 920 may be coupled to the supply container 910 by hook coupling, etc. Thus, an additional fastening member for coupling the container cover 920 and the supply container 910 may be omitted.

[0384] On the other hand, since the supply container 910 is configured to be open at the top, it is convenient to arrange structures of various shapes inside, and it is convenient to arrange various structures at the bottom of the container cover 920.

[0385] With the steam injection hole 932 as a reference, the water supply pipe 881 and the recovery pipe 815 are arranged on one side of the supply container 910 , and the steam pipe 813 is arranged on the other side of the supply container 910 .

[0386] That is, the water supply pipe 881 and the recovery pipe 815 may be arranged adjacent to each other, and the steam pipe 813 may be arranged farther from the water supply pipe 881 than the recovery pipe 815 .

[0387] Thus, the water moving toward the water supply pipe 881 can be supplied to the supply container 910 along direction I. The water supplied to the supply container 910 can be immediately discharged from the recovery pipe 815 along direction II and supplied to the steam generator 810. The steam supplied from the steam pipe 813 can be supplied to the supply container 910 along direction III and discharged from the steam injection hole 932, while the condensed water can be discharged from the recovery pipe 815 along direction II and supplied to the steam generator 810 again.

[0388] Hereinafter, an embodiment of the movable clothes hanger 1000 will be described in detail.

[0389] The movable hanger 1000 can also be configured to move back and forth linearly inside the inner shell 200. Thus, the clothes can move back and forth linearly inside the inner shell 200 and shake.

[0390] The movable hanger 1000 may be configured to enable the clothes to periodically shake at various frequencies.

[0391] For example, the movable hanger 1000 may also be configured in a structure as disclosed in Korean Patent Publication No. 10-1285890.

[0392] In addition, the moving hanger 1000 may be configured to shake the clothes by causing the clothes to reciprocate inside the inner case.

[0393] That is, in the clothes treating apparatus of the present invention, the movable hanger 1000 can be provided in any structure as long as it can swing the clothes in the inner housing.

[0394] Hereinafter, the structure of the movable hanger 1000 for reciprocating the clothes will be described.

[0395] Figure 16 It is a diagram showing the upper structure of the inner casing of the laundry processing apparatus according to the present invention.

[0396] The movable hanger 1000 of the clothes treating apparatus of the present invention may include a power transmission unit 1400 , which is disposed on the upper portion of the inner housing 200 and enables the clothes hanger 1900 to swing.

[0397] A hanging portion 1700 may be provided at a lower portion of the power transmission portion 1400 , and the clothes hanger 1900 may be placed on or hung on the hanging portion 1700 .

[0398] Thus, when the power transmission part 1400 moves, the hanging part 1700 is driven to move, which has the effect of shaking the clothes by making the clothes hanging part 1900 hung on the hanging part 1700 shake.

[0399] The power transmission unit 1400 may be provided in plurality, and the hanging unit 1700 coupled to the power transmission unit 1400 may also be provided in plurality. Thus, a large number of clothes corresponding to the number of the power transmission units 1400 can be placed inside the inner housing 200 and cared for.

[0400] The movable hanger 1000 may further include a driving unit 1200 for providing power to move the power transmission unit 1400 .

[0401] The driving unit 1200 may be exposed to the interior of the inner housing 200 as long as it can transmit power to the power transmission unit 1400. However, since the driving unit 1200 operates by receiving electrical energy, it is preferably not exposed to steam or hot air.

[0402] Thus, the driving unit 1200 may be disposed between the upper surface of the inner housing 200 and the box body 100 , thereby preventing the driving unit 1200 from being exposed to the accommodation space 220 .

[0403] The power transmission unit 1400 may penetrate the inner housing 200 and receive power from the driving unit 1200 and then transmit the power to the hanging unit 1700 .

[0404] The power transmission part 1400 may penetrate the upper surface of the inner housing 200 and extend into the accommodation space 220. The lower end of the power transmission part 1400 may be exposed to the accommodation space 220, and the upper end of the power transmission part 1400 may be exposed above the inner housing 200.

[0405] The power transmission part 1400 may be configured to be in a rod shape, a tube shape, a plate shape, etc., with a length greater than a thickness.

[0406] On the other hand, the upper surface of the inner housing 200 can support the load of the power transmission unit 1400 and the driving unit 1200. The power transmission unit 1400 moves when loaded with clothes, and the load on the driving unit 1200 is relatively large. Therefore, the laundry processing device 1 of the present invention may also be provided with a support portion 1800 to stably position the movable hanger 1000 on the upper surface of the inner housing 200.

[0407] The support portion 1800 may be disposed on the upper portion of the inner housing 200 and supported by being coupled to the box body 100. The support portion 1800 may be made of a metal material that is durable and difficult to deform.

[0408] The power transmission unit 1400 and the driving unit 1200 may be mounted on the support unit 1800 and disposed on an upper portion of the inner housing 200. The power transmission unit 1400 may penetrate the support unit 1800 and extend into the accommodation space 220.

[0409] On the other hand, the driving unit 1200 includes a motor that rotates a rotating shaft. The driving unit 1200 may be configured to move the power transmission unit 1400 using the power generated by the rotation of the rotating shaft.

[0410] However, it may be difficult to shake the power transmission unit 1400 with sufficient displacement simply by rotating the rotation shaft at the original position.

[0411] Therefore, the movable hanger 1000 may further include a displacement generating unit 1300 that is coupled to the rotating shaft rotated by the motor and generates a sufficient displacement (amount of position change) to move the power transmission unit 1400 .

[0412] The displacement generating unit 1300 may be connected to or combined with the driving unit 1200 .

[0413] For example, the displacement generating unit 1300 may be configured to transmit the power of the driving unit 1200 to the power transmitting unit 1400 .

[0414] The displacement generating unit 1300 may include an eccentric shaft that rotates along a larger path than the diameter of the rotating shaft. The eccentric shaft may be directly coupled to the rotating shaft of the driving unit 1200, or may be eccentrically coupled to or extended to the power shaft 1240 that rotates via the rotating shaft.

[0415] The displacement generating unit 1300 may be provided in any configuration as long as it can generate displacement that causes the power transmission unit 1400 to reciprocate within a predetermined range.

[0416] When the driving unit 1200 operates, the power generated by the rotating shaft may cause the displacement generating unit 1300 to be displaced, and the power transmitting unit 1400 may move along with the displacement of the displacement generating unit 1300 .

[0417] The displacement generating unit 1300 can directly move the power transmitting unit 1400 , but the power transmitting unit 1400 can also be moved by using an additional structure.

[0418] The movable hanger 1000 of the present invention may be configured to allow the power transmission part 1400 to reciprocate.

[0419] In addition, the mobile hanger 1000 of the present invention may also be configured to rotate the power transmission unit 1400. Specifically, the mobile hanger 1000 may be configured to reciprocate the power transmission unit 1400 within a predetermined angle range instead of reciprocating the power transmission unit 1400 along a straight line.

[0420] The power transmission unit 1400 can be configured to reciprocate clockwise or counterclockwise from a predetermined position, and the clothes placed on the power transmission unit 1400 can also be rotated clockwise or counterclockwise. The power transmission unit 1400 can be configured so that although it is rotated by the movable hanger 1000, its position does not change, such as moving to the left or right.

[0421] Even if the clothes rotate inside the inner case 200 due to the power transmission unit 1400, the movement of the center of gravity inside the inner case 200 can be restricted. Therefore, even if the mobile hanger 1000 is in operation, the vibration generated inside the inner case 200 can be greatly reduced, and the generation of noise can be minimized.

[0422] To this end, the mobile hanger 1000 may further include a reciprocating rotation unit 1500 that converts the continuous rotation energy generated by the driving unit 1200 or the displacement generating unit 1300 into a reciprocating rotation motion of the power transmitting unit 1400 .

[0423] The reciprocating rotating unit 1500 may be configured to connect the displacement generating unit 1300 and the power transmission unit 1400. The reciprocating rotating unit 1500 may be configured to connect the displacement generating unit 1300 and the power transmission unit 1400 at a position above the inner housing 200. By preventing the reciprocating rotating unit 1500 from being exposed to the accommodating space 220, the clothing may be prevented from being damaged by the reciprocating rotating unit 1500.

[0424] On the other hand, the movable hanger 1000 may also be configured to reciprocate only one of the plurality of power transmission parts 1400 .

[0425] However, if only one power transmission unit 1400 rotates, the clothes placed on the rotating power transmission unit may collide with the clothes placed on other power transmission units 1400 and be damaged. In addition, there is a hidden danger that the impact is transmitted to the mobile hanger 1000, causing damage to the mobile hanger 1000.

[0426] Therefore, it is preferred that the movable hanger 1000 is configured so that all of the plurality of power transmission parts 1400 rotate.

[0427] The movable hanger 1000 can rotate the plurality of power transmission units 1400 in unison. The movable hanger 1400 can be configured to rotate the plurality of power transmission units 1400 simultaneously at the same angle. Thus, the laundry processing apparatus of the present invention can prevent the power transmission units 1400 from colliding with each other.

[0428] Directly transmitting the power generated by the driving unit 1200 to the plurality of power transmission units 1400 may be beneficial for rotating all of the power transmission units 1400 .

[0429] However, if the driving unit 1200 directly transmits power to each of the power transmission units 1400 , the structure connecting the driving unit 1200 and all the power transmission units 1400 may become complicated.

[0430] Furthermore, if a plurality of drive units 1200 are provided, or if a plurality of drive units 1200 are connected to all power transmission units 1400, an excessive load may be applied to the inner housing 200 or the support unit 1800. Furthermore, the need to control the plurality of drive units 1200 may be inconvenient.

[0431] In addition, if the displacement generating unit 1300 and the reciprocating rotating unit 1500 are connected to transmit the power transmitted from one driving unit 1200 to all the power transmitting units 1400 respectively, the configuration and structure of the displacement generating unit 1300 and the reciprocating rotating unit 1500 become complicated, which may reduce reliability.

[0432] Therefore, the movable hanger 1000 may be configured such that one driving unit 1200 generates power to rotate the plurality of power transmission units 1400 .

[0433] In addition, the movable clothes hanger 1000 can be configured so that the power generated in the driving part 1200 can be preferentially transmitted to a part of the power transmission part 1400 or a part of the reciprocating rotating part 1500, and the remaining power transmission part 1400 or the remaining reciprocating rotating part 1500 can receive the power secondarily.

[0434] For example, the reciprocating rotating unit 1500 may be configured to receive power transmitted from the driving unit 1200 or the displacement generating unit 1300 and transmit the power to a portion of the power transmitting unit 1400. In other words, the mobile hanger 1000 is configured to transmit the power generated by the driving unit 1200 to a single reciprocating rotating unit 1500, thereby simplifying the design of the power transmission structure and minimizing power loss.

[0435] The movable hanger 1000 of the present invention may be configured to transmit the power transmitted from the driving unit 1200 to a reciprocating rotating unit 1500 , thereby rotating a specific power transmission unit 1400 connected to the reciprocating rotating unit 1500 .

[0436] In addition, the movable clothes hanger 1000 may further include a connecting portion 1600 configured to transmit the power transmitted to a specific power transmission portion 1400 to other power transmission portions 1400 .

[0437] For example, the connection portion 1600 may be configured to connect the plurality of power transmission units 1400 to each other. Thus, when any one of the power transmission units 1400 rotates, the connection portion 1600 may cause all of the plurality of power transmission units 1400 to rotate.

[0438] Figure 17 It is a figure which shows the operation mode of the movable clothes hanger of this invention.

[0439] Reference Figure 17 (a), if the driving unit 1200 is in operation, the power transmission unit 1400 may rotate to the right through the reciprocating rotation unit 1500. At this time, the power transmission unit 1400 connected to the connecting unit 1600 may also rotate to the right.

[0440] Reference Figure 17 (b), if the driving unit 1200 further operates, the power transmission unit 1400 may rotate to the left through the reciprocating rotation unit 1500. At this time, the power transmission unit 1400 connected to the connecting unit 1600 may also rotate to the left.

[0441] The power transmission unit 1400 may rotate left and right as the above process is repeated.

[0442] At this time, the power transmission unit 1400 may be configured to rotate left and right while being fixed at a predetermined position. The power transmission unit 1400 may be fixed to the support unit 1800 so that its position does not change in the front, back, left, and right directions during rotation.

[0443] The power transmission unit 1400 may be fixed so as not to move based on vertical, front-back, and width directions.

[0444] However, the power transmission unit 1400 can rotate left and right with the vertical direction or height direction of the power transmission unit as the rotation axis. As a result, when the driving unit 1200 is driven, the hanging unit 1700 can reciprocate left and right with the power transmission unit 1400 as the axis without displacement.

[0445] Reference Figure 17 (c), the clothes hanging portion 1900 may include: a hook portion 1910 placed on the hanging portion 1700; and a placement portion 1900 combined with the hook portion 1910. A surface portion 950 that prevents clothes from sliding may be provided on the surface of the placement portion 1950.

[0446] The placement portion 1950 may be bilaterally symmetrical with respect to the hook portion 1910. The hanger portion 1900 may be placed on the hanger portion 1700 such that the placement portion 1950 is arranged along the front-back direction.

[0447] If the power transmission unit 1400 rotates to the left, the left side of the placement portion 1950 of the hanger portion 1900 may rotate to the left with respect to the hook portion 1910, while the right side of the placement portion 1950 rotates to the right. In this case, the angle I of the left rotation of the placement portion 1950 may be the same as the angle θ of the right rotation of the placement portion 1950, and the distance moved by the left side of the placement portion 1950 may be the same as the distance moved by the right side of the placement portion 1950.

[0448] As a result, the weight and force moving to the left with respect to the hanger portion 1900 are the same as the weight and force moving to the right, and thus can cancel each other out.

[0449] Likewise, even if the power transmission unit 1400 rotates to the right, the weight and force moving to the left with respect to the hanger unit 1900 are the same as the weight and force moving to the right, and thus can cancel each other out.

[0450] As a result, even if the power transmission unit 1400 rotates, the forces applied to the hanger unit 1900 can be offset, thereby minimizing the vibration force or excitation force and inertial force generated by the hanger unit 1900 itself. Thus, by minimizing the inertial force generated in the plurality of power transmission units 1400, the vibration or noise generated in the entire movable hanger 1000 can be minimized, and the vibration or noise generated in the entire clothing processing device 1 can be significantly reduced.

[0451] As a result, even if the driving unit 1200 rotates at a maximum output, no large vibration is generated in the movable hanger 1000 or the entire clothing treating apparatus 1 .

[0452] Furthermore, the surfaces of the clothes hung on the hanger 1900 are rotated left and right and shaken, thereby ensuring a large shaking force.

[0453] As previously mentioned, the power transmission unit 1400 can be arranged to penetrate the inner housing 200 and, upon receiving the power, reciprocate clockwise and counterclockwise. As a result, the power transmission unit 1400 can reciprocate left and right while being fixed in position at the upper portion of the inner housing 200. The power transmission unit 1400 is fixed so as not to move in the vertical, horizontal, or lateral directions. Furthermore, not only the upper portion of the power transmission unit 1400, but also the lower portion of the power transmission unit 1400 is fixed so as not to move in the vertical, horizontal, or lateral directions.

[0454] That is, the power transmission unit 1400 may be configured to reciprocate and rotate within a predetermined angle in a manner of less than one rotation with a fixed rotation center.

[0455] As a result, no matter how fast the power transmission unit 1400 rotates, the position of the hanger unit 1900 is fixed and one end rotates or moves to one side while the other end rotates or moves to the other side, so that the force and vibration transmitted to the power transmission unit 1400 can offset each other.

[0456] Thus, vibration and noise generated by the power transmission unit 1400 , the hanging unit 1700 , and the clothing hanging unit 1900 inside the inner housing 200 can be minimized.

[0457] As a result, the laundry processing apparatus of the present invention can rotate the driving unit 1200 at a higher rpm, thereby causing the power transmission unit 1400 to reciprocate at a faster frequency.

[0458] In addition, the mobile hanger 1000 of the present invention is configured such that the power transmission unit 1400 rotates back and forth clockwise or counterclockwise at its original position. Therefore, as previously described, regardless of how fast the hanging unit 900 rotates, the vibration or inertial force generated by the hanging unit 1900 and the clothing can be offset when transmitted to the power transmission unit 1400.

[0459] As a result, in the movable hanger 1000 of the present invention, even if the driving unit 1200 is increased to a specific RPM or higher, the movable hanger 1000 is not damaged, and vibration or noise exceeding a limit value is prevented from occurring in the clothes treating apparatus.

[0460] Therefore, the clothes treating apparatus of the present invention can drive the driving part 1200 faster than the existing clothes treating apparatus using the movable clothes hanger, and can shake the clothes more strongly by driving the power transmission part 1400 at a faster frequency.

[0461] Thus, the laundry processing apparatus of the present invention can more reliably remove foreign matter attached to laundry and more effectively remove creases in laundry through the movable hanger 1000. In addition, the laundry processing apparatus of the present invention can expose the laundry to more steam by vibrating the laundry faster.

[0462] In addition, the laundry processing apparatus of the present invention can freely adjust the RPM of the driving unit 1200, thereby adjusting the driving frequency or driving cycle of the power transmission unit 1400 in accordance with the program.

[0463] Figure 18 FIG. 1 is a diagram showing an embodiment of a mobile clothes hanger 1000 according to the present invention.

[0464] The movable clothes hanger 1000 of the present invention can be configured to transmit the power of the driving unit 1200 only to any one of the plurality of power transmission units 1400 , and transmit the power transmitted to the specific power transmission unit 1400 to the remaining power transmission units 1400 through the connecting unit 1600 .

[0465] The displacement generating unit 1300 or the reciprocating rotating unit 1500 may be configured to collectively transmit the power generated by one driving unit 1200 to one power transmitting unit 1400. The connecting unit 1600 may transmit the power transmitted to a specific power transmitting unit 1400 to all the power transmitting units 1400.

[0466] The connecting portion 1600 may be formed of a rigid body and its length may not change. The connecting portion 1600 may be configured to connect all the power transmission portions 1400 .

[0467] Thus, when the connecting portion 1600 moves, all the power transmission portions 1400 can rotate simultaneously in the same direction and at the same angle.

[0468] The movable clothes hanger 1000 may include: a driving part 1200, fixed to the upper part of the inner shell 200, providing power for the movement of the power transmission part; a plurality of reciprocating rotating parts 1500, respectively combined with the plurality of power transmission parts 1400, and rotating by receiving the power from the driving part 1200 so that the rotation direction repeatedly changes; and a connecting part 1600, connecting the plurality of reciprocating rotating parts to each other.

[0469] The connecting portion 1600 may include a connecting rod configured to connect the plurality of reciprocating rotating portions 1500 so as to rotate the plurality of reciprocating rotating portions 1500 as a whole.

[0470] The connecting portion 1600 may be provided in a single piece.

[0471] The connecting portion 1600 may also be configured to connect all of the power transmission portions 1400 .

[0472] However, if the connecting portion 1600 is configured to connect the reciprocating transmission portion 1500 , the connecting portion 1600 may be disposed at a position higher than the supporting portion 1800 , thereby preventing the connecting portion 1600 from being exposed to the interior of the inner shell 200 .

[0473] The connecting portion 1600 is coupled to either the front or rear side of the reciprocating rotating portion 1500, and one or more of the displacement generating portion 1300 and the driving portion 1200 can be disposed on the other side of the front or rear side of the reciprocating rotating portion 1500. This prevents interference between the connecting portion 1600 and the driving portion 1200.

[0474] The connecting portion 1600 may be configured to reciprocate along a width direction of the inner housing 200 to rotate the plurality of reciprocating rotating portions 1500 .

[0475] The driving unit 1200 may include: a motor 1210 that rotates the rotating shaft 1210; a power shaft 1240 that is configured to rotate together with the rotating shaft 1210; and a transmission unit 1230 that connects the power shaft 1240 and the rotating shaft 1210 to transmit the rotational force of the rotating shaft 1210 to the power shaft 1240.

[0476] The motor 1210 can be fixed to the upper portion of the inner housing 200 and rotate the rotating shaft 1220. However, the rotating shaft 1220 rotates at a speed much higher than the appropriate period for the motor 1210 to reciprocate the power transmission unit 1400. Given this, if the RPM of the rotating shaft is reduced, there is a risk that the output of the motor 1210 cannot be transmitted to the power transmission unit 1400.

[0477] In order to solve this problem, the transmission unit 1230 may be configured to transmit the output of the rotating shaft 1220 to the power transmission unit 1400 as it is, but to reduce the RPM of the rotating shaft 1220 for transmission.

[0478] The transmitting portion 1230 may be connected to and rotated by the rotating shaft 1220 and may have a larger diameter than the rotating shaft 1220 so as to rotate. Thus, the transmitting portion 1230 may be configured to rotate at a slower speed than the RPM of the rotating shaft 1220 and transmit the torque of the rotating shaft 1220 .

[0479] The power shaft 1240 is rotatable by the transmission unit 1230 , is independently provided relative to the rotation shaft 1230 , and directly transmits power to the power transmission unit 1400 .

[0480] The reciprocating rotation unit 1500 may be provided to be coupled to the power transmission unit 1400 and rotatable together with the power transmission unit 1400 .

[0481] The reciprocating rotation part 1500 may include a reciprocating rod 1510 coupled to an upper portion of the power transmission part 1400 to rotate the power transmission part 1400 .

[0482] The reciprocating rod 1510 may be provided in the shape of a rib or a rod coupled to the support shaft 1410 at a rotation center.

[0483] The reciprocating rods 1510 may be respectively coupled to the upper ends of the plurality of power transmission parts 1400 , and a portion of the reciprocating rods 1510 may be configured to receive the power of the motor 1210 by being connected to the transmission part 1230 .

[0484] The reciprocating rod 1510 may be configured to reciprocate at a predetermined angle when the transmission unit 1230 is rotated by the motor 1210. The power transmission unit 1400 may be coupled to a rotation center of the reciprocating rod 510 and rotate together with the reciprocating rod 1510.

[0485] The plurality of reciprocating rods 1510 may be connected using a connecting portion 1600 .

[0486] The connecting portion 1600 may be configured to connect one end of a plurality of reciprocating rods 1510 .

[0487] Therefore, as long as any one of the plurality of reciprocating rods 1510 rotates, the connecting portion 1600 can move and drive the plurality of reciprocating rods 1510 to rotate simultaneously.

[0488] The power transmission unit 1400 and the reciprocating rod 1510 may be supported on the support unit 1800 . In addition, the motor 1210 and the transmission unit 1230 may also be supported on the support unit 1800 .

[0489] Figure 19 FIG. 1 is a diagram showing the movable hanger 1000 of the present invention being separated from the inner case 200 .

[0490] The power transmission part 1400 may extend from an upper portion to a lower portion of the inner housing, and the hanging part 1700 may be coupled to a lower portion of the power transmission part 1400 .

[0491] The reciprocating rotating part 1500 may be combined with each of the power transmission parts 1400 and may be easily connected to the driving part 1200 by being combined with the upper portion of the power transmission part 1400 .

[0492] A plurality of the power transmission unit 1400 and the reciprocating rotation unit 1500 may be provided and arranged at predetermined intervals along the width direction of the inner housing.

[0493] The connecting portion 1600 is configured to connect the plurality of power transmission units 1400 or the plurality of reciprocating rotation units 1500. Thus, the connecting portion 1600 can be configured to allow all of the plurality of power transmission units 1400 or the plurality of reciprocating rotation units 1500 to rotate simultaneously.

[0494] The power transmission unit 1400 may include a support shaft 1410 that passes through an upper portion of the inner housing 200 and is coupled to the reciprocating rod 1510 .

[0495] The support shaft 1410 may penetrate the support portion 1800 and be exposed at an upper portion of the support portion 1800 or an upper portion of the inner case 200 .

[0496] The power transmission unit 1400 may include an auxiliary support unit 1420 coupled to the support shaft 1410 and exposed to the receiving space. The auxiliary support unit 1420 may be in a rod shape, and the hanging unit 1700 may be coupled to and fixed to a lower portion of the auxiliary support unit 1420 .

[0497] The auxiliary support portion 1420 may be fixed to the support shaft 1410 and rotate together with the support shaft 1410. Thus, if the support shaft 1410 rotates via the reciprocating rod 1510, the auxiliary support portion 1420 coupled to the support shaft 1410 may also rotate and drive the hanging portion 1700 to rotate left and right.

[0498] The reciprocating rod 1510 may include a main rod 1511 that reciprocates by directly receiving power from the driving portion 1200 , and an auxiliary rod 1512 that receives power from the main rod 1511 through a connecting portion 1600 .

[0499] The main rod 1511 may be provided as a single one and directly receive power from the driving unit 1200 .

[0500] In the driving unit 1200 , the motor 1210 may include a vertical motor 1211 coupled to the supporting unit 1800 , and a vertical rotation shaft 1221 rotated by the vertical motor 1211 .

[0501] The transmission part 1230 may include: a power pulley 1231, which is combined with the vertical rotation shaft 1221 and rotates together with the vertical rotation shaft 1221; a transmission pulley 1232, which is combined with the power shaft 1240 to rotate the power shaft 1240; and a transmission belt 1233, which connects the power pulley 1231 and a portion of the outer circumference of the transmission pulley 1232.

[0502] The transmission unit 1230 may further include a pulley support portion 1224 that rotatably supports the power shaft 1240 and the transmission pulley 1232. The pulley support portion 1224 may support the transmission pulley 1232 so as to align with the power pulley 1231 and be positioned on the support portion 1800.

[0503] The power shaft 1240 may be configured to transmit the power transmitted from the rotation shaft 1220 to one end of the main rod 1511 .

[0504] The displacement generating unit 1300 may receive power by being coupled to the power shaft 1240. In addition, the displacement generating unit 1300 may be connected to the main rod 1511 to allow the main rod 1511 to reciprocate around the support shaft 410.

[0505] For example, the displacement generating unit 1300 may include an eccentric shaft that is eccentrically coupled to the power shaft 1240 and rotates at a predetermined radius with respect to the rotation center of the power shaft 1240 .

[0506] The displacement generating unit 1300 may be connected to the end of the main rod 1511. The displacement generating unit 1300 may rotate via the power shaft 1240, thereby causing the end of the main rod 1511 to reciprocate around the support shaft 410.

[0507] The connecting portion 1600 may include a connecting rod 1610 , which connects one end of the main rod 1511 that is not connected to the power shaft 1240 or the displacement generating portion 1300 and one end of the auxiliary rod 1512 .

[0508] The auxiliary rod 1512 may be configured such that the other end not coupled to the main rod 1511 is rotatably coupled to the support shaft 1410 , and extends from the position coupled to the support shaft 1410 in one direction to be connected to the connecting rod 1610 .

[0509] The connecting rod 1610 may be provided in the form of a straight frame connecting one end of the main rod 1511 and one end of the auxiliary rod 1512. In this case, one end of the main rod 1511 and one end of the auxiliary rod 1512 may be arranged side by side with respect to the connecting rod 1610 or the width direction.

[0510] The connecting rod 1610 may be provided as a single unit and allows the main rod 1511 and the auxiliary rod 1512 to rotate simultaneously around their respective support shafts 1410 .

[0511] The inner housing 200 may be provided with a through hole 230 , and a portion of the support portion 1800 is disposed in the through hole 230 , so that the power transmission portion 1400 is exposed to the accommodating space 220 .

[0512] The through hole 230 may be provided on the upper surface 22 of the inner housing, and the through hole 230 may be provided along the configuration direction of the power transmission part 1400 .

[0513] For example, the power transmission parts 1400 may be spaced apart from each other along the width direction of the inner housing, and the through holes 230 may be arranged along the width direction of the inner housing.

[0514] The laundry treating apparatus 1 of the present invention may include a support frame 120 , which is disposed outside the inner housing and supports the housing 100 .

[0515] The support frame 120 can be made of a metal material and disposed at each corner of the housing 100 or the inner housing 200 to maintain the appearance of the laundry processing apparatus. Both ends of the support portion 1800 can be supported by the support frame 120, thereby preventing unnecessary impact or load from being transmitted to the upper surface 220 of the inner housing.

[0516] Figure 20 10 is a diagram showing the operation mode of the mobile clothes hanger 1000 of the present invention.

[0517] Reference Figure 20 (a), the main rod 1511 may include a main body 15111 , and the main body 15111 is combined with the support shaft 1410 and the connecting rod 1610 .

[0518] The main body 15111 may include a main center hole 15115 coupled to the support shaft 1410 and capable of rotating the support shaft 1410 , and may be configured to extend toward both sides from the main center hole 15115 .

[0519] A main receiving hole 15112 for receiving power from the driving part 1200 may be provided at one end of the main body 15111 , and a main transmission hole 15113 may be included at the other end of the main body 15111 , and the connecting rod 1610 may be disposed and coupled to the main transmission hole 15113 .

[0520] The main body 15111 may further include a stepped portion 15114 extending from the central hole toward the main receiving hole 15112 to form a step. Due to the stepped portion 15114, one end of the main body 15111 or the main transfer hole 15113 may be positioned below the main central hole 15115.

[0521] Thus, the length of the power shaft 1240 or the eccentric shaft 1310 arranged at the upper portion of the main center hole 15115 extending from the transmission portion 1230 can be ensured.

[0522] On the other hand, the auxiliary rod 1512 may include an auxiliary body 15121 having an auxiliary center hole 15125 coupled to the support shaft 1410 and an auxiliary transfer hole 15123 extending to one side from the auxiliary center hole 15125 and coupled to the connecting rod 1610 .

[0523] The length of the auxiliary body 15121 may be smaller than the length of the body 15111 .

[0524] The distance from the main center hole 15115 to the main transfer hole 15113 can be set to be the same as the distance from the auxiliary center hole 15125 to the auxiliary transfer hole 15123.

[0525] The connecting rod 1610 may be disposed above the auxiliary transfer hole 15123 and the main transfer hole 15113 and connect the auxiliary rod 1512 and the main rod 1511 to each other.

[0526] Reference Figure 20 (b), the driving unit 1200 may be configured such that the power shaft 1240 is inserted into the main receiving hole 15112. Thus, the main receiving hole 15112 may be rotated left and right by directly rotating the power shaft 1240.

[0527] In other words, sufficient displacement for rotating the main receiving hole 15112 leftward and rightward with respect to the main center hole 15115 may not be generated only by the rotation of the power shaft 1240 .

[0528] To this end, the displacement generating portion 1300 may be configured to be coupled to the power shaft 1240 and generate a displacement greater than a rotation radius of the power shaft 1240 .

[0529] The displacement generating unit 1300 may be configured to convert the rotational motion of the power shaft 1240 into a displacement motion that reciprocates within a predetermined range. The displacement motion is transmitted to the reciprocating rotating unit 1500, thereby causing the power transmitting unit 1400 to reciprocate.

[0530] As mentioned above, the displacement generating unit 1300 may include the eccentric shaft 1310 . The eccentric shaft 1310 extends to the power shaft 1240 and rotates along a trajectory according to a predetermined radius.

[0531] The eccentric shaft 1310 may have a diameter smaller than that of the power shaft 1240 , and may be coupled to or extended from the power shaft 1240 at a predetermined distance from the rotation center of the power shaft 1240 .

[0532] Thus, when the power shaft 1240 rotates, the eccentric shaft 1310 may rotate while drawing a circle having a radius equal to the distance from the power shaft 1240 .

[0533] The diameter of the eccentric shaft 1310 may be set to be smaller than the diameter or width of the main receiving hole 15112 .

[0534] The eccentric shaft 1310 may be inserted into the main receiving hole 15112 and supported.

[0535] However, the predetermined radius of rotation of the eccentric shaft 1310 may be larger than the width or diameter of the main receiving hole 15112. As a result, if the eccentric shaft 1310 rotates, the main receiving hole 15112 may be pushed by the eccentric shaft 1310 and move left and right with respect to the main center hole 15115.

[0536] As a result, when the eccentric shaft 1310 rotates in a specific direction x, the main receiving hole 15112 of the main body 1511 also rotates back and forth along the prescribed direction y. As a result, the center hole 15115 of the main body also rotates in the same direction as the main receiving hole 15112, and the main transfer hole 15113 can rotate back and forth in the direction z opposite to the prescribed direction.

[0537] When the eccentric shaft 1310 rotates, the support shaft 1410 and the main center hole 15115 rotate back and forth together, thereby driving the power transmission unit 1400 to rotate back and forth, and also causing the main transmission hole 15113 to rotate back and forth, thereby causing the connecting rod 1610 to move back and forth, and thus causing the auxiliary rod 1521 to reciprocate around the auxiliary center hole 15125 and the support shaft 1410. The power transmission unit 1400 coupled to the auxiliary rod 1521 can also rotate back and forth.

[0538] In the power transmission unit 1400 , a thread may be provided along the outer circumference of the upper portion of the support shaft 1410 .

[0539] The main transfer hole 15113 and the auxiliary center hole 15125 may be directly coupled and fixed to the support shaft 1410 via threads.

[0540] However, the power transmission part 1400 may also include a transmission coupling part 1415, which is coupled to the thread of the support shaft 1410 to fix the support shaft 1410 to the main transmission hole 15113 and the auxiliary center hole 15125 after the support shaft 1410 directly passes through the main transmission hole 15113 and the auxiliary center hole 15125.

[0541] Therefore, the support shaft 1410 is coupled to the reciprocating rod 1510 through the transmission coupling portion 1415 , so that the support shaft 1410 and the reciprocating rod 1510 can rotate simultaneously.

[0542] Hereinafter, based on the above configuration, an embodiment in which the control unit 700 of the laundry processing apparatus of the present invention executes an arbitrary program will be described.

[0543] Figure 21 FIG. 1 is a diagram illustrating a process in which the clothes treating apparatus of the present invention executes a clothes treating program.

[0544] In the laundry processing apparatus of the present invention, an allowable power level may be set as the maximum usable power level. If it is sensed that the power consumption exceeds the allowable power level, the control unit 700 of the laundry processing apparatus of the present invention may block the power supply.

[0545] The allowable power may be less than the power consumed when the first heater 841, the second heater 842, and the compressor 342 are driven simultaneously. As a result, the laundry processing apparatus of the present invention is configured not to drive all of the steam heater 840 and the compressor 342 simultaneously.

[0546] As a result, the laundry processing apparatus of the present invention is configured such that the first heater 841 and the second heater 842 cannot be driven simultaneously while the compressor 342 is being driven, and the compressor 342 cannot be driven while the first heater 841 and the second heater 842 are being driven simultaneously.

[0547] Therefore, the clothes treating apparatus of the present invention may be configured such that the maximum steam that can be supplied is not supplied together with the hot air being supplied to the inside of the inner case.

[0548] However, the allowable power amount may be greater than the power consumed when the first heater 841 and the second heater 842 are driven simultaneously. Furthermore, the allowable power amount may be greater than the power consumed when the first heater 841 and the compressor 342 are driven simultaneously. Furthermore, the allowable power amount may be greater than the power consumed when the second heater 842 and the compressor 342 are driven simultaneously.

[0549] As a result, the first heater 841 and the second heater 842 can be driven at the same time, the first heater 841 and the compressor 342 can be driven at the same time, and the second heater and the compressor 342 can be driven at the same time.

[0550] Therefore, in the clothes treating apparatus of the present invention, if the compressor 342 is not driven, the maximum steam that can be supplied can be supplied to the inside of the inner case by driving the first heater 841 and the second heater 842 at the same time.

[0551] In addition, in the clothing processing device of the present invention, by simultaneously driving any one of the first heater 841 and the second heater 842 and the compressor 342, the steam can be supplied to the interior of the inner shell 200 while hot air is supplied to the interior of the inner shell 200, and hot air can be supplied to the interior of the inner shell 200 while steam is supplied.

[0552] In the laundry processing apparatus of the present invention, the first heater 841 and the second heater 842 can be driven simultaneously in the initial stage to rapidly heat the water within the steam generator 810 and preferentially generate steam. Thereafter, if steam is generated, the laundry processing apparatus of the present invention can drive only one of the first heater 841 and the second heater 842 to maintain the water temperature at a boiling point, for example, and to continuously generate steam.

[0553] However, in this case, the injection amount of steam after the steam is generated may be reduced compared to when the first heater 841 and the second heater 842 are driven simultaneously.

[0554] The laundry treatment apparatus of the present invention can adjust the steam supply amount by driving only one of the first heater 841 and the second heater 842. Therefore, even for materials such as silk or cashmere that are easily affected by moisture and temperature, a care operation can be fully performed by supplying only a small amount of steam.

[0555] In the laundry processing apparatus of the present invention, only one of the first heater 841 and the second heater 842 may be used when supplying steam to the interior of the inner case, thereby reducing the amount of electricity required for steam supply.

[0556] Furthermore, in the laundry processing apparatus of the present invention, the compressor 342 can be driven simultaneously with the steam supply, thereby rapidly increasing the temperature inside the inner housing. Consequently, the laundry processing apparatus of the present invention can rapidly complete a drying process for removing moisture from wet laundry, as well as perform laundry care operations such as sterilizing, deodorizing, and removing creases from laundry.

[0557] Figure 21 (a) is a diagram illustrating an embodiment of a method for controlling a clothes treating apparatus according to the present invention.

[0558] In the clothing treatment device of the present invention, if a care program or a standard program for performing the care operation is executed, the following can be performed: a steam preparation step A1 of heating water by driving a steam heater; and if steam is generated by heating water during the execution of the steam preparation step A1, a steam injection step A2 of supplying the steam to the clothing.

[0559] Generally, a care operation aims to supply moisture to clothes in a dry state, and therefore a large amount of steam needs to be sprayed onto the clothes.

[0560] Therefore, the laundry treating apparatus of the present invention can simultaneously drive the first heater 841 and the second heater 842 in both the steam preparing step A1 and the steam spraying step A2.

[0561] In consideration of an allowable amount of power, the compressor 342 may not be driven in the steam preparing step A1 and the steam injecting step A2.

[0562] The clothes treating apparatus of the present invention performs a waiting step A3 of providing time for the clothes to absorb moisture using the supplied steam.

[0563] After the waiting step A3 is executed for a predetermined time, the laundry processing apparatus of the present invention executes a cooling step A4 in which only the air supply fan is driven before the compressor to reduce the surface temperature of the laundry. The cooling step A4 can prevent the laundry from being damaged by heat.

[0564] When the temperature inside the inner shell 200 drops and the moisture content of the clothes is sufficient, the clothes treating apparatus of the present invention performs a drying step A5 of driving at least one of the compressor 342 and the air supply fan 351 .

[0565] Through the drying step A5, the moisture contained in the clothes can be dried while performing clothing care operations such as deodorization and crease removal. Compared with all the steps previously performed, the duration of the drying step A5 can be the longest.

[0566] On the other hand, since the compressor cannot be driven during the steam injection step A2, hot air cannot be supplied. Therefore, before reaching the drying step A5, the temperature inside the inner casing 200 and the temperature of the refrigerant flowing in the heating unit 400 can be relatively low.

[0567] Therefore, in the aforementioned control method, only if the drying step A5 lasts longer can the care performance, including any one of complete drying, sterilization, deodorization, and crease removal of the clothes, be ensured.

[0568] Figure 21 (b) is a diagram illustrating another embodiment of a method for controlling a laundry processing apparatus according to the present invention.

[0569] However, as mentioned above, since the clothes treating apparatus of the present invention divides the heater into a plurality of heaters, some of the heaters and the compressor can be driven simultaneously.

[0570] For example, since the steam heater 840 includes the first heater 841 and the second heater 842, any one of the first heater 841 and the second heater 842 and the compressor can be driven simultaneously.

[0571] Therefore, in the clothing processing device of the present invention, the heater and the compressor are driven simultaneously before the drying step, thereby enabling the temperature inside the inner shell 200 to rise rapidly before the drying step, thereby ensuring that the temperature and time required for complete drying, sterilization, deodorization, and crease removal of the clothing are performed faster.

[0572] As a result, the duration of the drying step can be shortened compared to before. Furthermore, the drying step can be set to the longest duration during the treatment process. By shortening the duration of the drying step, the duration of the entire treatment process can be significantly reduced. Furthermore, by shortening the compressor drive time, energy efficiency can be improved.

[0573] If any program capable of caring for or managing clothes is executed, the clothes treating apparatus of the present invention may perform a steam preparation step B1 of fully driving the steam heater 840 in order to supply steam to the clothes.

[0574] In the steam preparation step B1 , the controller 700 may drive all the heaters of the steam heater 840 because the faster the steam is generated, the shorter the care operation time.

[0575] In other words, in the steam preparation step B1 , the control unit 700 may use the maximum power of the steam heater 840 to heat water.

[0576] If the steam heater 840 is composed of the first heater 841 and the second heater 842 , water may be heated by driving the first heater 841 and the second heater 842 simultaneously.

[0577] In the steam preparation step B1 , if the sensing device 860 senses that steam is generated inside the steam housing 810 , the laundry treating apparatus of the present invention may perform a preheating step B2 of driving only a portion of the steam heater 840 .

[0578] That is, after the steam housing 810 generates steam, even if only one of the first heater 841 and the second heater 842 is driven, the steam can continue to be generated and supplied to the inner housing 200 .

[0579] In the preheating step B2 , the controller 700 may drive either the first heater 841 or the second heater 842 to supply heat to the interior of the inner case 200 .

[0580] Thus, the laundry processing apparatus of the present invention can use the steam to increase the temperature inside the inner housing 200 and the moisture content of the laundry starting from the preheating step B2. In addition, in the preheating step B2, since only a portion of the steam heater 840 is used, additional power can be ensured.

[0581] In the preheating step B2 , the laundry processing apparatus of the present invention may drive at least one of the compressor 342 and the air supply fan 351 , thereby supplying hot air into the inner casing 200 .

[0582] As a result, in at least a portion of the preheating step B2, the compressor 342, the blower fan 351, and a portion of the steam heater 840 can be driven in an overlapping manner.

[0583] In the preheating step B2, any one of the first heater 841 and the second heater 842 and the compressor 342 may be driven simultaneously. Steam and hot air may be supplied to the interior of the inner casing 200 simultaneously.

[0584] If either the first heater 841 or the second heater 842 is driven simultaneously with the compressor 342, the temperature inside the inner housing 200 can be raised from the initial stage of the treatment procedure, allowing hotter air to flow into the evaporator 341. As a result, the heat exchange performance of the evaporator 341 is enhanced, and the condenser 343 can be heated to a higher temperature. This allows hotter air to be supplied to the interior of the inner housing 200, allowing the interior of the inner housing 200 to reach the optimal or minimum temperature required for the treatment procedure more quickly. Consequently, the time required to perform subsequent treatment procedures can be significantly shortened.

[0585] In addition, the coefficient of performance (COP) of the entire heating unit 340 can also be increased.

[0586] The preheating step B2 may include at least one of a section in which any one of the first heater 841 and the second heater 842 and the compressor 342 are driven simultaneously and a section in which only the compressor 342 is driven.

[0587] For example, in the preheating step B2, there is not only a section in which the steam heater 840 and the compressor 342 are driven simultaneously, but there may also be a section in which only the compressor 342 is driven.

[0588] However, it is preferable that the section in which only the compressor 342 is driven is arranged after the section in which the steam heater 840 and the compressor 342 are driven.

[0589] This is because supplying high-heat-capacity air to the evaporator 341 before driving the compressor 342 facilitates driving the heating unit 340. Specifically, supplying steam to the inner casing 200 via the steam heater 840 not only increases the temperature inside the inner casing 200 but also increases the absolute humidity, allowing high-heat-capacity air to come into contact with the evaporator 341.

[0590] Specifically, the preheating step B2 may include a first interval in which any one of the first heater 841 and the second heater 842 and the compressor 342 are driven, and a second interval in which driving of the first heater 841 and the second heater 842 is interrupted and only the compressor 342 is driven.

[0591] The first section can increase the temperature inside the inner case 200 and the heat of the air flowing into the circulation duct 320 by supplying hot air and steam to the inner case 200 .

[0592] Through the second interval, hot air can be officially supplied to the interior of the inner shell 200 to meet the minimum temperature conditions for performing care such as deodorization, crease removal, and sterilization of clothing.

[0593] In the preheating section B2, the first heater 841 may be driven. Thus, a greater amount of steam may be supplied to the inner shell 200 than when the first heater 841 is driven, thereby further increasing the temperature inside the inner shell 200 and the heat of the air flowing into the circulation duct 320.

[0594] Alternatively, in the preheating section B2, the second heater 841 may be driven.

[0595] Thus, in the preheating section B2, the temperature inside the inner housing 200 can be gradually increased and the increased temperature can be maintained stably for a longer period of time, thereby ensuring the time required for sterilization.

[0596] In addition, it can prevent clothes from being deformed due to high humidity.

[0597] On the other hand, the laundry processing apparatus of the present invention may be configured to interrupt the driving of the steam heater 840 if the temperature inside the inner shell 200 rises sharply or the temperature of the refrigerant discharged from the compressor 342 exceeds a limit temperature in the preheating interval B2.

[0598] Furthermore, the laundry processing apparatus of the present invention can be configured to repeatedly operate and interrupt (ON / OFF) either the first heater 841 or the second heater 842 during the preheating interval B2. Specifically, the control unit 700 can repeatedly operate the following process: if the refrigerant temperature approaches or exceeds a limit temperature, the steam heater 840 can be interrupted during operation; if the refrigerant temperature reaches a safe temperature below the limit temperature, the steam heater 840 can be activated again. Furthermore, the control unit 700 can repeatedly operate the following process: if the internal temperature of the inner casing approaches or exceeds a target temperature, the steam heater 840 can be interrupted during operation; if the internal temperature reaches a cooling temperature below the target temperature, the steam heater 840 can be activated again.

[0599] On the other hand, even if the steam heater 840 is driven intermittently, since the purpose of the preheating interval B2 is to quickly increase the temperature inside the inner shell 200, the time when the first heater 841 and the second heater 842 are driven can be set to be longer than the time when the first heater 841 and the second heater 842 are stopped.

[0600] The preheating interval B2 may be performed during a predetermined time, and the preheating interval B2 may be terminated if the temperature inside the inner casing or the temperature of the refrigerant is maintained at a predetermined temperature or above for a predetermined time.

[0601] After the preheating period B2 is completed, the laundry treating apparatus of the present invention may perform a steam injection step B3 for formally supplying steam to the interior of the inner housing 200. In the steam injection step B3, a large amount of steam may be supplied to the inner housing 200 by simultaneously driving the first heater 841 and the second heater 842.

[0602] Since the steam spraying step B3 is performed after the clothes placed in the inner housing 200 are heated to a predetermined level through the preheating step B2, the moisture content of the entire clothes can be greatly increased.

[0603] Compared with the steam injection step A2 without the preheating step B2, the execution time of the steam injection step B3 can be shorter because a predetermined level of steam has been supplied in the preheating step B2, and thus the amount of steam to be additionally supplied is set to be smaller.

[0604] If the guaranteed time for the clothes to fully absorb moisture has passed, the steam spraying step B3 may be ended.

[0605] If the steam injection step B3 is completed, the drying step B6 for drying the clothes with hot air may be performed. However, if the steam injection step B3 is completed, a waiting step B4 for a predetermined time may be added to ensure that the steam injected into the inner housing 200 has time to penetrate the entire clothes.

[0606] The waiting step B4 may correspond to a state in which the steam heater 840 and the compressor 342 are not driven.

[0607] The waiting step B4 can prevent the steam injected into the inner shell from evaporating directly before being absorbed by the clothes, and prevent the surface temperature of the clothes from rising sharply and causing damage to the clothes by supplying additional hot air when the surface temperature of the clothes rises due to the steam.

[0608] The drying step B6 is a step in which hot air is supplied to the inner housing 200 by driving the compressor 342. Therefore, if hot air is supplied directly before the temperature inside the inner housing 200 drops below a safe temperature, the temperature inside the inner housing 200 may rise above the limit temperature, causing damage to the clothes.

[0609] Therefore, before performing the drying step B6, the cooling step B5 of driving the air supply fan 352 may be performed. In the cooling step B5, the controller 700 drives the air supply fan 352, but stops driving the compressor 342 and the steam heater 340.

[0610] In the cooling step B5 , the air inside the inner casing 200 may be circulated along the circulation duct 200 to be cooled.

[0611] If the temperature inside the inner shell 200 drops below a safe temperature, or the cooling step B5 is performed for a required time, the cooling step B5 may be terminated.

[0612] The laundry processing apparatus of the present invention may perform a drying step B6 of supplying hot air to the laundry. The drying step B6 may be performed until the moisture content of the laundry drops below a predetermined level.

[0613] The controller 700 may detect that the moisture content has fallen below a predetermined level by sensing the temperature inside the inner casing 200 or the temperature of the refrigerant.

[0614] For example, when the moisture content of the clothes is high, even if the drying step B6 is performed, the temperature of the clothes flowing into the circulation duct 320 again will not rise due to the heat of vaporization, or even if it rises, it will not rise sharply.

[0615] However, when most of the clothes are dried and the moisture content is below a predetermined level, the temperature of the clothes flowing into the circulation duct 320 may rise sharply due to the low heat of vaporization, and may eventually reach the temperature of the hot air.

[0616] Here, the temperature of the refrigerant may also change in a manner similar to the temperature of the refrigerant flowing into the circulation pipe 320 .

[0617] If the control unit 700 senses that the moisture content of the clothes has become low, the clothes have been sufficiently dried, and the minimum time required for care has passed, the control unit 700 may end the drying step B6.

[0618] Alternatively, if the time for which the clothes are exposed to a temperature above the minimum drying temperature reaches or exceeds a minimum time, the control unit 700 may end the drying step B6.

[0619] As a result, the clothes processing apparatus of the present invention can be further configured with a preheating step B2 before the drying step B6, thereby increasing the total time for the temperature inside the inner shell 200 to reach above the minimum temperature condition, thereby significantly reducing the duration of the drying step B6.

[0620] On the other hand, in the clothes treating apparatus of the present invention, after the driving of the compressor 342 is interrupted in the preheating section B2, the driving of the compressor 342 may be kept interrupted until before the drying step B6 is performed.

[0621] Figure 22 FIG. 1 is a diagram illustrating an embodiment of a clothes treating apparatus according to the present invention performing a drying process.

[0622] If the drying process is performed, the drying process may be performed in the order of a first stage or heating stage, a second stage or constant rate stage, a third stage or falling rate stage, and a fourth stage or cooling stage.

[0623] Wet clothes or clothes with a higher moisture content than that of the clothes to be removed may be placed inside the inner housing 200 .

[0624] Reference Figure 22 In step (a), if the first stage is executed, at least one of the compressor 342 and the air supply fan 352 may be driven. This heats the refrigerant while also heating the air inside the inner housing 200. With the aid of the air supply fan 352, the air circulates through the inner housing 200 and the circulation duct 320 while gradually increasing in temperature. During this process, moisture in the clothes may begin to evaporate.

[0625] Reference Figure 22In (b), if the first stage continues for a predetermined time, high-temperature air (hot air) capable of vaporizing moisture from the clothing is supplied to the interior of the inner shell 200. During this process, as the amount of moisture evaporated from the clothing gradually increases, more heat of vaporization is absorbed from the hot air. As a result, despite the supply of hot air to the interior of the inner shell 200, the rate of increase in the temperature within the inner shell 200 may drop below a reference value, or the temperature within the inner shell 200 may remain at a constant rate.

[0626] For example, the reference value may be set to a rate of 1 degree per minute or 0.3 degree per minute, but this is only one embodiment, and the rate of increase of temperature versus time may be set arbitrarily as long as the first stage and the second stage can be distinguished.

[0627] The control unit 700 may drive the mobile hanger 1000 in the second stage. The hanger 1900 placed on the mobile hanger 1000 may reciprocate or vibrate. Thus, the physical force condition may be removed in the constant rate stage.

[0628] In the second stage, the moisture content of the clothes gradually decreases from 100%, thereby achieving moisture removal. However, in the second stage, as the moisture contained in the clothes evaporates, the clothes continue to absorb heat of vaporization from the air inside the inner shell 200, and the temperature inside the inner shell 200 is lower than the set temperature.

[0629] The set temperature may be defined as a temperature at which creases on clothing can be removed. For example, the set temperature may be equivalent to 37 degrees Celsius.

[0630] Reference Figure 22 In step (c), if the second stage continues for a predetermined period of time, the moisture content of the clothing drops below the removal moisture content. From this point on, the amount of water evaporating from the clothing decreases dramatically, and the heat of vaporization absorbed from the air inside the inner housing 200 also decreases. As a result, the third stage can be entered, where the rate of increase in the temperature inside the inner housing 200 rises above a reference value.

[0631] If the third stage starts, the temperature inside the inner shell 200 reaches or exceeds the set temperature. Specifically, in the third stage, the temperature inside the inner shell 200 may reach or exceed a drying temperature higher than the set temperature.

[0632] For example, the drying temperature may be set to 50 degrees or higher.

[0633] In addition, if the third stage is performed, the laundry is in a state of being almost completely dried, so the moisture content of the laundry drops to less than 5%, which is much lower than the removal moisture content.

[0634] If the third stage is executed for a predetermined time or longer, the controller 700 may terminate the drying process. The controller 700 may execute a fourth stage of interrupting the operation of the compressor 342 and driving the air supply fan 352 until the temperature inside the inner casing 200 drops to a safe temperature lower than the set temperature.

[0635] The safety temperature may be equivalent to normal temperature. For example, the safety temperature may be set to 25 degrees.

[0636] Reference Figure 22 (d), the control unit 700 may also additionally perform a step of removing creases and wrinkles from the clothes.

[0637] The steam heater 840 may be driven to supply steam to the inside of the inner case 200. Thus, the moisture content of the laundry in the inner case 200 may be increased to a removal moisture content.

[0638] In addition, the control unit 700 may apply a physical force to the clothes by driving the movable hanger 1000 .

[0639] As a result, in the removing stage, the control part 700 can remove the creases and wrinkles of the clothes by driving the steam heater 840 and the moving hanger 1000 simultaneously.

[0640] Since the removal phase is performed additionally after the fourth phase, the temperature inside the inner housing 200 may be higher than the set temperature. Therefore, during the removal phase, the controller 700 may interrupt the driving of the compressor.

[0641] If the removal phase is executed, a cooling phase may be executed to reduce the internal temperature of the inner casing 200 to a safe temperature lower than the set temperature. In the cooling phase, the air supply fan 352 may be driven, while the steam heater 840 and the compressor 342 are blocked.

[0642] On the other hand, in either the removal stage or the cooling stage, the compressor 342 may be driven again to dry the moisture supplied from the steam heater 840 .

[0643] As a result, the clothes treating apparatus of the present invention can remove creases and wrinkles from the clothes by additionally performing the removing stage after drying the clothes up to the fourth stage.

[0644] Figure 23 It shows Figure 22 The diagram shows the progress of the drying program.

[0645] Reference Figure 23 (a) and Figure 23 (b) If the drying process is executed, the driving of the compressor 342 may be started, and the driving of the compressor 342 may be maintained without interruption until the drying process is completed.

[0646] In addition, when the compressor 342 is driven, the air supply fan 352 may also be driven simultaneously.

[0647] As a result, hot air can be continuously supplied to the interior of the inner case 200 during the execution of the drying process.

[0648] If the driving of the compressor 342 starts, the first stage in which the temperature inside the inner casing 200 gradually increases until the temperature of the refrigerant rises may be performed.

[0649] Afterwards, if the heating of the refrigerant is completed, a second stage may be performed in which hot air is supplied into the inner case 200 to vaporize moisture contained in the clothes so that the rate of increase of the temperature inside the inner case 200 is lower than the reference value.

[0650] In the second stage, the set temperature may not be reached due to vaporization heat of the laundry.

[0651] Thereafter, if the moisture content of the clothes reaches less than 5%, the fourth stage can be executed in which the internal temperature of the inner shell 200 exceeds the set temperature and continues to rise to above the drying temperature.

[0652] Since the compressor 342 is always driven, the power consumption of the entire laundry processing device can be reduced by blocking the driving of the steam heater 342. In addition, in the drying process, since the moisture content in the laundry is high, steam may not be supplied to the laundry.

[0653] The clothes can be shaken by driving the movable hanger 1000. Thus, not only can the moisture contained in the clothes be shaken off, but the entire clothes can also be evenly exposed to the hot air.

[0654] Alternatively, since the weight of the clothes is large in the interval where the moisture content of the clothes is higher than the removal moisture content as in the first stage, the driving of the movable hanger 1000 may be blocked.

[0655] As a result, if the crease removal stage is not performed, Figure 22 and Figure 23In the embodiment of the present invention shown, there may not be an interval that satisfies the removal condition until the fourth stage. Therefore, in this embodiment of the drying program control method, although the clothes can be dried quickly, the creases and wrinkles of the clothes may not be removed.

[0656] Figure 24 FIG. 1 is a diagram illustrating another embodiment of a drying process performed in the clothes treating apparatus of the present invention.

[0657] The clothes treating apparatus of the present invention can supply steam into the inner casing in an initial period when the drying process is performed through the drying process.

[0658] When the moisture content of the clothes is high, even if steam is supplied to the clothes, the moisture content of the clothes will not increase significantly or will remain almost the same, so no additional energy is required to remove the moisture caused by the steam. In addition, the heat of the steam is not carried away in the form of vaporization heat, so the temperature inside the inner housing 200 can be increased sharply.

[0659] As a result, the clothes treating apparatus of the present invention can achieve the removal condition by supplying steam at the beginning of the drying process to raise the temperature inside the inner housing to above the set temperature, thereby automatically removing the creases and wrinkles of the clothes.

[0660] Reference Figure 24 (a) In the clothes treating apparatus of the present invention, if a drying process is performed, a first stage of supplying heated air to the inside of the inner case 200 by driving the compressor 342 and the air supply fan 352 may be performed.

[0661] In the first stage, the control unit 700 may drive the steam heater 840 .

[0662] Specifically, the controller 700 may drive either the first heater 841 or the second heater 842 to generate steam while the compressor 342 is being driven.

[0663] That is, the controller 700 may first drive the compressor 342 and then drive either the first heater 841 or the second heater 842 together with the compressor 342 .

[0664] Alternatively, the controller 700 may simultaneously drive the first heater 841 and the second heater 842 to heat the water contained in the steam housing 381 and then drive the compressor 342. Steam may then be supplied by driving either the first heater 841 or the second heater 842.

[0665] That is, the controller 700 may first drive the first heater 841 and the second heater 842 , and then drive the compressor 342 .

[0666] However, even in this case, the driving of either the first heater 841 or the second heater 842 is interrupted before driving the compressor 342, so when driving the compressor 342, only either the first heater 841 or the second heater 842 may be driven.

[0667] Therefore, it can be considered that when the compressor 342 is driven first, only one of the first heater 841 and the second heater 842 is driven.

[0668] The controller 700 can simultaneously drive either the first heater 841 or the second heater 842 and the compressor 342 during at least a portion of the first stage to simultaneously supply hot air and steam into the inner casing 200. As a result, the temperature inside the inner casing 200 can be raised to a set temperature or above starting from the first stage.

[0669] Although the control unit 700 can simultaneously drive any one of the first heater 841 and the second heater 842 and the compressor 342 from the start of the first stage, it can also simultaneously drive any one of the first heater 841 and the second heater 842 and the compressor 842 after a specified time has passed since the start of the first stage.

[0670] Thus, the time for boiling water can be ensured by driving the first heater 841 and the second heater 842 at the same time at the beginning of the first stage and blocking the driving of the compressor 342, or even if the first heater 841 and the second heater 842 are not driven at the same time at the beginning of the first stage, it is possible to prevent steam from being supplied at the initial stage when the moisture content of the clothes is very high.

[0671] In the first stage, due to the driving of the steam heater 840 , the internal temperature of the inner casing 200 may rise to a limit temperature higher than a set temperature.

[0672] The limit temperature may be set to a temperature that ensures that the internal temperature of the inner case 200 does not drop below the set temperature even if steam is not supplied and moisture contained in the clothes evaporates.

[0673] The limit temperature may be set as a specific temperature, or may be defined as a temperature that is increased by a predetermined % (based on 0 degrees Celsius) or a predetermined temperature compared to the initial temperature.

[0674] For example, the limit temperature may be equivalent to 45 degrees Celsius, or a temperature that is 100% higher than the initial temperature or 30 degrees Celsius.

[0675] Reference Figure 24 (b), if the first stage is passed and the second stage is entered, the moisture content of the clothes can reach the removal moisture content.

[0676] In addition, since the steam supply and the hot air supply are simultaneously performed in the first stage, the clothes may also reach the moisture removal rate in the first stage.

[0677] As a result, the moisture content of the clothes may be removed in the specific intervals of the first and second stages.

[0678] Even in the second stage, steam can be supplied to the interior of the inner casing 200 in the initial period. This can prevent the internal temperature of the inner casing 200 from falling below the set temperature due to the heat of vaporization.

[0679] In addition, the control unit 700 may drive the movable hanger 1000 in the second stage, thereby applying a physical force to the clothes.

[0680] Of course, the control unit 700 may also drive the movable hanger 1000 in the first stage.

[0681] As a result, all crease removal conditions can be satisfied in the second stage.

[0682] Reference Figure 24 (c) If the second stage is performed so that the moisture content of the clothes drops below the removal moisture content, the third stage may be performed.

[0683] However, since all creases have been removed in the second stage, the third stage can be performed in a state where the clothes are free of creases and wrinkles.

[0684] In the third stage, since the moisture content of the clothes is low, the internal temperature of the inner shell 200 can rise to above the drying temperature.

[0685] In the third stage, the first heater 841 and the second heater 842 may be completely blocked. This can omit unnecessary operations that increase the moisture content of the dried laundry and prevent the temperature inside the inner housing 200 from becoming excessively high.

[0686] Reference Figure 24 (d) If the temperature inside the inner shell 200 rises to above the drying temperature that can ensure the drying of the clothes, or the drying time passes under the condition of being above the drying temperature, the control unit 700 can directly execute the aforementioned fourth stage.

[0687] As a result, the clothes treating apparatus of the present invention can perform the first to fourth stages to dry the clothes while omitting the additional crease removal stage.

[0688] It can be considered that the drying program of the clothes processing apparatus of the present invention includes a crease removal stage or the crease removal stage is automatically executed.

[0689] In addition, the clothes treating apparatus of the present invention can automatically remove creases and wrinkles of clothes when performing a drying process.

[0690] That is, the laundry processing apparatus of the present invention can omit the operation of supplying additional steam and drying the laundry again after the moisture content of the laundry drops below 5%. Furthermore, the laundry processing apparatus of the present invention can also omit the operation of interrupting and restarting the compressor until the drying cycle ends, thereby activating both the first heater 841 and the second heater 842. Furthermore, the laundry processing apparatus of the present invention can also omit the inefficient process of increasing the moisture content of the laundry again after the moisture content has fallen below the removal rate.

[0691] In addition, the clothes treating apparatus of the present invention can automatically remove creases and wrinkles from clothes during a drying process, and can prevent drying delay or reduction in drying efficiency due to removal of creases and wrinkles from clothes.

[0692] Therefore, the clothes treating apparatus of the present invention can save the user from taking additional measures to remove creases and wrinkles from clothes.

[0693] Figure 25 Is to show the execution Figure 24 FIG. 1 is a diagram showing a control state of a clothes processing apparatus when using a control method.

[0694] The laundry processing apparatus of the present invention can simultaneously drive either the first heater 841 or the second heater 842 during the operation of the compressor 342 in the first stage. This allows the temperature inside the inner housing 200 to rise faster and higher. Consequently, even if the moisture content of the laundry is very high and has not yet reached the moisture removal level, the temperature inside the inner housing 200 can be raised to above the set temperature starting from the first stage.

[0695] On the other hand, in the clothing processing device of the present invention, since the steam heater 840 and the compressor 342 are driven simultaneously, the internal temperature of the inner shell 200 further rises above the set temperature and rises to the limit temperature, thereby achieving the effect that the execution time of the first stage is set to be longer.

[0696] In addition, since the first stage ends under high temperature conditions, it is also possible to achieve an effect of shortening at least one of the second stage and the third stage.

[0697] For example, normally, the first stage ends at first time t1 when the compressor 342 starts driving and the driving rpm reaches the maximum rpm. However, in the laundry processing apparatus of the present invention, the rate of increase of the temperature inside the inner housing 200 is equal to or higher than the reference value after the first time t1 and until the third time t3, so it can be considered that the first stage is executed until the third time t3.

[0698] In addition, in the clothes treating apparatus of the present invention, after the third time t3, the rising rate of the internal temperature of the inner case 200 begins to be lower than the reference value.

[0699] Therefore, in the clothes treating apparatus of the present invention, the second stage may start from the third time t3.

[0700] In addition, since the temperature rise rate rises above the baseline value again from the seventh time t7, the third stage can be regarded as starting from the seventh time. Since the temperature inside the inner shell 200 exceeds the drying temperature from the eighth time, the third stage can be regarded as being executed from the seventh time t7 to the eighth time t8.

[0701] The fourth stage may be performed from the eighth time to the ninth time when the driving of the compressor 342 ends.

[0702] In the embodiment of the drying process in which steam is not originally supplied to the interior of the inner casing 200, the rate reduction stage is executed even after the ninth time. However, in the embodiment of the drying process in which steam and hot air are simultaneously supplied at the initial stage, the drying process can be terminated at the eighth time because the temperature inside the inner casing 200 is kept higher than the set temperature. That is, Figure 24 The embodiments can be compared with Figure 22 The embodiment of the present invention greatly shortens the execution time of the drying process.

[0703] Reference Figure 25 (a) and Figure 25 In (b), the controller 700 may maintain driving of the compressor 342 after the initial time t0 at which the driving of the compressor is started, until a ninth time t9 at which the drying process ends.

[0704] The controller 700 may drive the compressor 342 from an initial time t0 and maintain the operation until a ninth time t9 at which the drying process ends.

[0705] The controller 700 may also drive the compressor 342 and the air supply fan 352 simultaneously in the first to third stages, and may drive the air supply fan 352 without driving the compressor 342 in the fourth stage.

[0706] Reference Figure 25(c), the control unit 700 may drive the steam heater 840 before driving the compressor 342.

[0707] The control unit 700 may drive the entire steam heater 840 at maximum power before the initial time t0 to quickly heat the water contained in the steam housing 810. For example, before driving the compressor 342, the control unit 700 may drive the first heater 841 and the second heater 842 simultaneously to generate steam as quickly as possible.

[0708] If steam is generated by driving the first heater 841 and the second heater 842 at the same time, the control part 700 may drive only one of the first heater 841 and the second heater 842 .

[0709] When driving either the first heater 841 or the second heater 842 , the controller 700 may start driving the compressor 342 .

[0710] Alternatively, the controller 700 may drive either the first heater 841 or the second heater 842 after driving the compressor 342 .

[0711] In addition, the control unit 700 can heat the water to a certain extent by simultaneously driving the first heater 841 and the second heater 842 before the initial time t0, and when the initial time t0 is reached, it can further heat the water by driving either the first heater 841 or the second heater 842 while driving the compressor 342.

[0712] Alternatively, the controller 700 may first drive the compressor 342 at the initial time t0, and then heat the water by driving either the first heater 841 or the second heater 842 after the initial time t0. Therefore, while the compressor 342 is being driven, a portion of the steam heater 840 may be driven to heat the water, and steam may be generated only at the first time t1, thereby starting to supply steam to the interior of the inner casing 200 from the first time t0.

[0713] In either case, as long as the compressor 342 starts to drive, the driving of the compressor 342 will not be blocked until the end of the third stage, and hot air can be supplied to the interior of the inner shell 200 first, and then steam can be supplied.

[0714] As a result, the control part 700 may drive the steam heater 840 to supply steam into the inner case 200 starting from the first stage.

[0715] The controller 700 may keep the steam heater 840 driven until the temperature inside the inner housing 200 rises to a set temperature or higher. In other words, the controller 700 may keep the first heater 841 or the second heater 842 driven.

[0716] Furthermore, the control unit 700 may maintain the steam heater 840 even after the temperature inside the inner casing 200 rises to or above the set temperature. For example, the control unit 700 may maintain the operation of the first heater 842 or the second heater 842 until the temperature inside the inner casing 200 rises to a limit temperature higher than the set temperature.

[0717] This is because, even if the internal temperature of the inner shell 200 is above the set temperature, if the drive of the steam heater 840 is interrupted, the moisture in the clothes inside the inner shell 200 absorbs the heat of vaporization when evaporating, which may cause the internal temperature of the inner shell 200 to drop below the set temperature again.

[0718] Therefore, even if the internal temperature of the inner shell 200 rises above the set temperature, the control unit 700 can keep driving the first heater 841 or the second heater 842 until entering the second stage corresponding to the increase rate of the internal temperature of the inner shell 200 being below the reference value.

[0719] As a result, the clothes treating apparatus of the present invention can maintain the internal temperature of the inner housing 200 above the set temperature in at least a portion of the first and second stages, thereby meeting the conditions for removing creases and wrinkles from clothes.

[0720] If the second stage is reached or the temperature inside the inner housing 200 reaches a limit temperature, the control unit 700 may interrupt the operation of the first heater 841 or the second heater 842. Specifically, if the second stage is reached or the temperature inside the inner housing 200 reaches a limit temperature, the control unit 700 may interrupt the supply of steam to the inner housing 200. This prevents the moisture content of the laundry from unnecessarily increasing or decreasing.

[0721] Of course, the control unit 700 can continue to supply steam until at least a portion of the second stage by continuously driving the first heater 841 or the second heater 842, thereby completely preventing the internal temperature of the inner casing 200 from falling below the set temperature.

[0722] Since the clothes are dried from the first stage, the moisture content of the clothes decreases from the first stage.

[0723] Even if the clothes initially placed in the inner housing 200 are completely wet and have a moisture content of 100%, the moisture content of the clothes can be reduced to the moisture removal rate starting from the second time t2, which is the third time before entering the second stage. In other words, the moisture content of the clothes can be reduced to 45% from the first stage.

[0724] In addition, from the second time t2 to the sixth time t6 equivalent to the second stage or the fifth time t5 earlier than the sixth time, the moisture content of the clothes can be equivalent to 45% to 5%, which can directly meet the moisture content removal condition.

[0725] In addition, the moisture content may be removed before the sixth time, which is before the seventh time of executing the third stage.

[0726] In summary, in the laundry processing apparatus of the present invention, from the second time to the sixth time, which is equivalent to the first stage and the second stage, the internal temperature of the inner shell 200 is higher than the set temperature, and the laundry is in a moisture removal state.

[0727] Therefore, in the clothing processing apparatus of the present invention, the control unit 700 can remove the physical force transmitted to the clothing by driving the movable hanger 1000 in a portion of the first stage from the second time to the sixth time and a portion of the second stage.

[0728] As a result, all the removal conditions are satisfied in a partial section of the first stage from the second time to the sixth time and a partial section of the second stage, and therefore these sections can be set as the crease removal section A.

[0729] That is, the crease removal section A can be defined as a section where the temperature of the clothes is above the set temperature and the moisture content of the clothes is equivalent to the removal moisture content, and a section where the removal conditions are satisfied by applying a physical removal force.

[0730] The clothes treating apparatus of the present invention may drive the movable hanger 1000 at least in the crease removal section A.

[0731] The controller 700 may also intermittently drive the steam heater 840 during the crease removal section A. Specifically, the controller 700 may repeatedly turn the first heater 841 or the second heater 842 on and off. This prevents excessive steam supply, prevents a sudden increase in the temperature inside the inner casing 200, and maintains compressor reliability.

[0732] From a different perspective, if the temperature inside the inner casing 200 reaches a limit temperature higher than the set temperature, the controller 700 may intermittently drive the steam heater 840. The limit temperature may be a temperature at which the temperature of the refrigerant fed into the compressor 342 or the refrigerant discharged from the compressor 342 reaches a critical temperature that threatens the reliability of the compressor 342.

[0733] For example, the limit temperature may correspond to 90 degrees Celsius.

[0734] Therefore, in a temperature range above a limit temperature, the control unit 700 may intermittently drive the first heater 841 or the second heater 842 .

[0735] Although the controller 700 can supply steam to the interior of the inner casing 200 during the crease removal interval A, it can interrupt the operation of the steam heater 840 at the third time t3, which is earlier than the sixth time t6 at which the crease removal interval A ends. This can prevent the humidity inside the inner casing 200 from being unnecessarily increased or energy being wasted during the crease removal interval A.

[0736] The crease removal interval A can be set from the second time to the sixth time, but can also be set shorter as long as the set time, which is the shortest time for removing the crease, is included between the second time and the sixth time.

[0737] That is, during the set time in the crease removal section A, the control unit 700 may rock the hanger 1000 or drive the steam heater 840 to maintain the temperature above the set temperature. In other words, steam may be supplied to the interior of the inner housing 200 during the set time, and after the set time has elapsed, the steam heater 840 may be stopped from being driven even before the sixth time.

[0738] For example, the set time may be equivalent to 15 minutes.

[0739] Reference Figure 25 (d), the control unit 700 may drive the movable hanger 1000 in the crease removal section A at least during a set time.

[0740] If the moving hanger 1000 is not driven before the crease removal section A, the control unit 700 may drive the moving hanger 1000 during the crease removal section A at least for a set time.

[0741] Therefore, if the movable hanger 1000 is driven while the steam heater 840 is driven, even if the set time has not elapsed after the steam heater is driven, the movable hanger 1000 can maintain the driving speed for a predetermined time until the set time elapses.

[0742] That is, even if the steam heater 840 is not driven for the set time, the temperature inside the inner housing 200 may remain above the set temperature. However, the mobile hanger 1000 can only meet the physical force removal condition if it is driven for the set time. For example, the steam heater 840 may be blocked at the third time t3, but the mobile hanger 1000 can still be driven until at least the sixth time t6.

[0743] If viewed from the perspective of driving the moving hanger 1000 and the steam heater 840, the aforementioned control method can be analyzed as follows.

[0744] The moving hanger 1000 may be driven such that at least a portion of a driving section overlaps with a driving section of the steam heater 740 .

[0745] The controller 700 may drive the movable hanger 1000 when the temperature inside the inner housing 200 is at least equal to or higher than the set temperature.

[0746] In addition, the control unit 700 may drive the movable hanger 1000 while driving the first heater 841 or the second heater 842 .

[0747] In addition, if the movable hanger is driven at a first frequency of 1 rpm before the crease removal section A, the controller 700 may drive the movable hanger at a second frequency of 2 rpm, which is faster than the first frequency, in the crease removal section A.

[0748] If the moving hanger 1000 starts to be driven before the steam heater 840 is driven, the controller 700 may drive the moving hanger 1000 faster during the driving section of the steam heater 840 .

[0749] If the moving hanger 1000 is not driven before the steam heater 840 is driven, the controller 700 may drive the moving hanger 1000 in at least a portion of the section in which the steam heater 840 is driven.

[0750] Thus, a physical force greater than the removal physical force is applied to the clothing in the crease removal section A, so that creases and wrinkles in the clothing can be reliably removed by better satisfying the removal conditions.

[0751] The controller 700 may interrupt the driving of the movable hanger 1000 after the crease removal section A, or drive the movable hanger 1000 at a third frequency (3 rpm) slower than the second frequency. This prevents overload of the movable hanger 1000 and saves energy during the drying process.

[0752] The first frequency may be set to be lower than the third frequency. This prevents excessive energy consumption by the moving hanger 1000 in order to shake heavy laundry due to high moisture content, and minimizes vibration generated in the entire laundry processing apparatus.

[0753] If the moving hanger 1000 is driven during the driving of the steam heater 840 , the controller 700 may not drive the moving hanger 1000 or may drive the moving hanger 1000 slowly after the driving of the steam heater 840 ends.

[0754] The controller 700 may control the steam supply unit 800 to be driven so that at least a portion of the interval in which the steam supply unit 800 is driven overlaps with the interval in which the movable hanger 1000 is driven at the second frequency.

[0755] The control part 700 may drive the moving hanger 1000 at the second frequency after driving the steam supply part 800 .

[0756] As a result, the clothes treating apparatus of the present invention can drive or drive the moving hanger 1000 fastest in at least a portion of the first and second stages, and not drive or drive the moving hanger 1000 slowest before that.

[0757] If the above process is described with the driving of the movable hanger 1000 as the center, it can be analyzed as follows.

[0758] The control unit 700 may drive the movable hanger 1000 at a first frequency or keep it stopped when the temperature inside the inner shell is below a set temperature. Furthermore, the control unit 700 may drive the movable hanger 1000 at a second frequency faster than the first frequency when the temperature inside the inner shell is above a set temperature.

[0759] If the moving hanger 1000 is driven at the second frequency during the reference time, the control part 700 may then drive the moving hanger 1000 at a third frequency lower than the second frequency.

[0760] If the rising rate of the inner case internal temperature becomes higher than a reference value or the inner case internal temperature reaches a drying temperature higher than the set temperature, the controller 700 may drive the movable hanger 1000 at a third frequency slower than the second frequency.

[0761] The control unit 700 may set the driving frequency of the movable hanger 1000 differently according to the internal temperature of the inner housing 200 .

[0762] Specifically, the control unit 700 may drive the movable hanger 1000 at a first frequency until the internal temperature of the inner shell reaches a set temperature, and drive the movable hanger 1000 at a second frequency faster than the first frequency after the internal temperature of the inner shell reaches the set temperature.

[0763] The controller 700 may drive the movable hanger 1000 at a third frequency lower than the second frequency in a period after the internal temperature of the inner case reaches a drying temperature higher than the set temperature.

[0764] The control unit 700 may drive the moving hanger 1000 at a third frequency lower than the second frequency after driving the moving hanger 1000 at the second frequency for a set time.

[0765] The second frequency of 2 rpm may be set as the fastest frequency for driving the moving clothes rack during execution of the program.

[0766] If the moisture content of the laundry drops below the removal moisture content, the third stage can be executed. The third stage corresponds to the period in which the rate of increase in the temperature inside the inner housing 200 again becomes higher than the reference value. The crease removal period A can end before the third stage. Therefore, the steam heater 840 can end before the third stage, and the steam heater 840 can be turned off during and after the third stage.

[0767] If the internal temperature of the inner casing 200 reaches or exceeds the drying temperature, the controller 700 may interrupt the driving of the compressor 342 , while the driving of the air supply fan 352 may be maintained at least partially.

[0768] On the other hand, the laundry processing apparatus of the present invention can drive the second heater 842 while simultaneously driving the steam heater 840 and the compressor 342 during a drying cycle including the crease removal section A. This reduces the amount of steam supplied to the interior of the inner housing 200, thereby preventing the moisture content of the laundry from increasing, and allowing the focus to be on raising the temperature inside the inner housing 200 to above the set temperature.

[0769] The power consumption of the second heater 842 may be set so that the amount of steam generated by the second heater 842 is equivalent to 50 to 150% of the dehumidification capacity of the evaporator.

[0770] In addition, the amount of water and energy consumed when raising the temperature inside the inner casing 200 to above a set temperature can be minimized.

[0771] On the other hand, the driving of the steam heater 840 is interrupted at least in the second stage, which is equivalent to the interval in which the temperature rise rate is below the baseline value or the temperature change amplitude inside the inner shell 200 is below a specific range. Therefore, it can be regarded as interrupting the driving of the first heater or the second heater in the interval in which the temperature change amplitude inside the inner shell is below the specific range.

[0772] The specific range may be equivalent to 5 degrees.

[0773] In addition, in the control method of the clothes treating apparatus of the present invention, since the steam supply is blocked after the third stage, it can be considered that the driving of the steam heater is blocked after the drying temperature is reached.

[0774] Figure 26 FIG. 1 is a diagram illustrating another embodiment of a drying process performed in the clothes treating apparatus according to the present invention.

[0775] The clothes treating apparatus of the present invention may also drive the steam heater 840 and the compressor 342 in different crease removal sections A.

[0776] That is, the clothes treating apparatus of the present invention may always drive the steam heater 840 at the maximum power, or the steam heater 840 may be designed as a single heater instead of the first heater and the second heater.

[0777] The following description will focus on the different contents to avoid duplication with the aforementioned embodiments.

[0778] In the clothes treating apparatus of the present invention, when the drying process is executed, a preparation phase may be performed in which the temperature of the refrigerant circulating in the heating unit 340 is increased by driving the compressor 342 .

[0779] The preparation phase may correspond to a phase in which the driving RPM of the compressor 342 is increased to a maximum RPM, thereby increasing the temperature of the refrigerant to a target temperature at which the drying process can be performed.

[0780] The preparation phase may be performed until time a (ta).

[0781] If the preparation stage is performed, the clothes treating apparatus of the present invention may perform a first stage of driving the steam heater 840 .

[0782] When the steam heater 840 is configured as a single heater, the first stage is equivalent to driving the single heater at maximum output. When the steam heater 840 is configured as a plurality of heaters, the first stage is equivalent to driving the entire heater.

[0783] If the steam heater 840 is driven at maximum output, it cannot be driven simultaneously with the compressor 342. However, by driving the steam heater 840 at maximum output, the temperature inside the inner casing 200 can be raised to a set temperature or higher more quickly.

[0784] The controller 700 may increase the internal temperature of the inner housing 200 to a guaranteed temperature that is higher than a set temperature.

[0785] The guaranteed temperature may be equivalent to a temperature that can ensure that the internal temperature of the inner casing 200 remains above a set temperature for a set time when the driving of the steam heater 840 is interrupted and the compressor 342 is driven again.

[0786] The first stage may be executed until time b (tb).

[0787] In the first stage, the control unit 700 may always keep the steam heater 840 driven, or may intermittently and repeatedly drive the steam heater 840.

[0788] If the first stage is completed, the controller 700 may block the driving of the steam heater 840 and drive the compressor 342 and the air supply fan 352 .

[0789] If air flows into the inner shell 200 due to the driving of the air supply fan 352, the moisture contained in the clothes evaporates, so the internal temperature of the inner shell 200 drops due to the absorption of vaporization heat, and the internal temperature of the inner shell 200 can drop to lower than the set temperature before time c (tc).

[0790] However, due to the preheating stage and the supply of hot air by the compressor 342, the temperature inside the inner case 200 stops decreasing and increases. Therefore, the temperature inside the inner case 200 may increase again to a temperature higher than the set temperature from time c.

[0791] From time b (tb) to time c (tb), and then to time d (tb) where the temperature increase rate is above the reference value, the temperature increase rate remains below the reference value. Therefore, the period from time b (tb) to time d (tb) can be defined as the second stage.

[0792] The crease removal section A can be satisfied as long as the internal temperature of the inner shell 200 reaches the set temperature during the second stage.

[0793] The crease removal section A corresponds to a section where the temperature of the clothes is equal to or higher than the set temperature and the moisture content of the clothes is equal to the removal moisture content, and all the removal conditions are satisfied by applying a physical removal force.

[0794] The control unit 700 may start entering the crease removal zone A when the internal temperature of the inner housing 200 reaches the set temperature at least for the second time.

[0795] The crease removal interval A is satisfied in the second stage. That is, in the second stage, the moisture content of the clothes satisfies the removal moisture content and the temperature inside the inner shell is equal to or higher than the set temperature.

[0796] Therefore, in the drying process, the control unit 700 may drive the movable hanger 1000 at least in the crease removal section A. Thus, a physical force for removing the crease may be applied to the clothes.

[0797] As a result, all the removal conditions are achieved in the crease removal section A, so that creases and wrinkles of the clothes can be removed.

[0798] The crease removal section A may be completed before time d (tb) which is a third stage entry section in which the rate of increase of the internal temperature of the inner case 200 becomes larger than a reference value.

[0799] The third stage may be performed until the internal temperature of the inner shell 200 reaches a temperature above the drying temperature for a period of time f (tf).

[0800] From the second stage to the third stage, the driving of the compressor 342 may be maintained, while the driving of the steam heater 840 may be blocked.

[0801] 28( d ), the control unit 700 may drive the movable hanger 1000 in the crease removal section A. If the movable hanger 1000 is not driven before the crease removal section A, the control unit 700 may drive the movable hanger 1000 in the crease removal section A for at least a set time.

[0802] The controller 700 may be configured such that the driving of the compressor 342 and the driving of the movable hanger 1000 at least partially overlap, while the driving of the compressor 342 and the driving of the steam heater 840 do not overlap.

[0803] In addition, the moving hanger 1000 may be driven simultaneously with the driving of the steam heater 840. The moving hanger 1000 may be driven before and after the driving of the steam heater 840.

[0804] In addition, if the control unit drives the movable hanger at a first frequency of 1 rpm before the crease removal section A, the control unit 700 may drive the movable hanger at a second frequency of 2 rpm faster than the first frequency in the crease removal section A.

[0805] Thus, in the crease removal section A, the removal condition is better satisfied by applying a physical force greater than the removal physical force to the clothes, thereby reliably removing creases and wrinkles from the clothes.

[0806] The controller 700 may interrupt the driving of the movable hanger 1000 after the crease removal section A, or drive the movable hanger 1000 at a third frequency (3 rpm) slower than the second frequency. This prevents overload of the movable hanger 1000 during the drying process and saves energy.

[0807] The first frequency may be set to be lower than the third frequency. This prevents excessive energy consumption by the moving hanger 1000 in order to shake heavy laundry due to high moisture content, and minimizes vibration generated in the entire laundry processing apparatus.

[0808] If the movable hanger 1000 is driven while the steam heater 840 is being driven, the controller 700 may drive the movable hanger 1000 faster in at least a portion of the time after the steam heater 840 is driven. Alternatively, the movable hanger 1000 may be driven slowly thereafter.

[0809] The control part 700 may drive the moving hanger 1000 at the second frequency after driving the steam supply part 800 .

[0810] As a result, the clothes treating apparatus of the present invention can drive or drive the moving hanger 1000 fastest in at least a portion of the constant rate phase, while previously the moving hanger 1000 may not be driven or driven slowest.

[0811] If the description is centered on the driving of the mobile hanger 1000, the process is analyzed as follows.

[0812] The controller 700 may drive the movable hanger 1000 at a first frequency or keep the movable hanger 1000 stopped in a range where the temperature inside the inner housing is lower than a set temperature.

[0813] In addition, the control unit 700 may drive the movable hanger 1000 at a second frequency faster than the first frequency starting from the interval in which the temperature inside the inner housing reaches a set temperature or higher for the second time.

[0814] The control part 700 may drive the moving hanger 1000 at a third frequency lower than the second frequency after driving the moving hanger 1000 at the second frequency for a set period of time.

[0815] If the rising rate of the inner case internal temperature becomes higher than a reference value or the inner case internal temperature reaches a drying temperature higher than the set temperature, the controller 700 may drive the movable hanger 1000 at a third frequency slower than the second frequency.

[0816] The control unit 700 may set a driving frequency of the movable hanger 1000 differently according to the internal temperature of the inner case 200 .

[0817] Specifically, the control unit 700 can drive the movable clothes hanger 1000 at a first frequency until the internal temperature of the inner shell rises to the set temperature for the second time, and after the internal temperature of the inner shell rises to the set temperature for the second time, the control unit 700 can drive at a second frequency faster than the first frequency.

[0818] The controller 700 may drive the movable hanger 1000 at a third frequency lower than the second frequency in a period after the internal temperature of the inner case reaches a drying temperature higher than the set temperature.

[0819] The control unit 700 may drive the movable hanger 1000 at the second frequency for a set time and then drive the movable hanger 1000 at a third frequency lower than the second frequency.

[0820] The second frequency of 2 rpm may be set as the fastest frequency at which the mobile hanger is driven during execution of the program.

[0821] If the internal temperature of the inner casing 200 reaches or exceeds the drying temperature, the controller 700 may interrupt the driving of the compressor 342 and maintain at least a portion of the driving of the air supply fan 352 .

[0822] The present invention can be modified and implemented in various forms, so the protection scope of the present invention is not limited to the above-mentioned embodiments. Therefore, if the modified embodiments include the constituent elements of the claims of the present invention, they should be deemed to fall within the protection scope of the present invention.
