Description

[Technical Field]

[0001] The present invention relates to a clothing treatment device and a control method thereof, and more particularly to a clothing treatment device and a control method thereof that supplies steam and hot air to clothing to perform a refreshing process such as sterilizing, removing wrinkles, deodorizing, and drying the clothing. [Background technology]

[0002] Generally, a clothing treatment device is a concept that includes (has; constitutes; constructs; sets; includes; contains; contains) a washing machine that wets clothes with water to make a compress, and then removes foreign matter through the chemical action of detergent and physical action such as drum rotation, and a dryer that dries the damp clothes using hot air and steam.

[0003] Recently, however, clothing care machines have emerged that keep dry clothes comfortable and clean without wetting them. These clothing care machines supply steam or hot air to the clothes while they are hanging, deodorizing them and then performing a refresh process to dry or sterilize them.

[0004] This clothing care machine can selectively add fragrance to clothing, and has recently become an important part of clothing treatment equipment along with washing machines and dryers.

[0005] A clothing care machine that performs a clothing refreshing process must include a steam supply unit that supplies steam to the clothing in order to accommodate the clothing in a dry state.

[0006] FIG. 1 shows a conventional clothing treatment device equipped with a steam supply unit.

[0007] Referring to Korean Patent Publication No. 10-2020-0057545, a conventional clothing processing device includes a cabinet 1 that forms the exterior and an inner case 2 that is provided inside the cabinet 1 and on which clothing is hung.

[0008] The clothing treatment device includes a circulation duct 13 at the bottom of the inner case 2 for circulating the air in the inner case 2, a heat exchanger 15 provided in the circulation duct 13 for exchanging heat with the air, and a compressor 14 for supplying high-temperature refrigerant to the heat exchanger 15. When the compressor 14 is driven, hot air is supplied to the inner case 2, raising the temperature inside the inner case 2 and drying or sterilizing the clothing.

[0009] The clothing treatment device also includes a steam tank 16 that is provided outside the circulation duct 13 and stores water, and a heater 17 that is housed in the steam tank 16 and heats the water to generate steam. When the heater 17 is driven, steam is supplied into the inner case 2 to deodorize the clothing or remove wrinkles from the clothing.

[0010] Meanwhile, the clothes stored inside the inner case 2 are hung in a dry state. Therefore, in order to efficiently refresh the clothes, it is necessary to supply a sufficient amount of moisture to the inside of the inner case 2 to refresh the clothes.

[0011] Therefore, the heater 17 has a relatively large capacity so that the clothes hung in the inner case 2 are sufficiently moistened. For example, the heater 17 has a larger electric capacity than heaters used in washing machines and dryers that supply steam to wet clothes.

[0012] As a result, conventional clothing treatment devices have a fundamental limitation in that the heater 17 and compressor 14 cannot be driven simultaneously in order to avoid exceeding the allowable electrical capacity.

[0013] Therefore, when the heater 17 is driven to supply steam into the inner case 2, there is a problem in that hot air is not supplied into the inner case 2. That is, although the supply of steam can increase the moisture content of the clothes and raise the temperature inside the inner case 2 to a predetermined level, there is a problem in that the temperature inside the inner case 2 cannot be maintained above the minimum temperature required for deodorization, sterilization, and drying.

[0014] As a result, when the steam 2 is supplied to the inside of the inner case 2, there is a limitation in that the performance of deodorizing and sterilizing clothes cannot be guaranteed.

[0015] Furthermore, in conventional clothing treatment devices, a sufficient amount of moisture needs to be supplied from hot air to refresh the clothing, and all of the supplied moisture needs to be dried, so the compressor 17 is driven after the heater 17 is driven.

[0016] As a result, conventional clothing processing devices had the problem that the temperature inside the inner case 2 could not be maintained at the minimum temperature before the compressor 17 was driven, and therefore the effect of the refresh process was not achieved.

[0017] Therefore, since the temperature inside the inner case 2 can be raised to and maintained at the minimum temperature only after the compressor 17 is driven during the refreshing process, there is a fundamental limitation in that the process of refreshing the clothes itself is significantly delayed.

[0018] In addition, since steam cannot be supplied to the inside of the inner case 2 at the initial stage of operation of the compressor 17, the air in contact with the heat exchanger 15 is at a relatively low temperature. As a result, the air discharged from the inner case 2 does not have enough heat to exchange heat with the refrigerant flowing through the heat exchanger 15, which causes a problem in that the coefficient of performance (COP) of the heat pump system cannot be ensured.

[0019] As described above, the heater 6 is provided with a large capacity to increase the moisture content of the clothes inside the inner case 2, so when the heater 6 is activated, the humidity inside the inner case 2 rises rapidly.

[0020] Therefore, conventional clothing treatment devices have the problem of being unable to treat clothing that is sensitive to moisture, such as silk or cashmere.

[0021] Meanwhile, a clothing treatment device equipped with a steam supply unit that supplies steam to a drum containing clothing in the washing machine or the dryer has also appeared.

[0022] FIG. 2 shows a conventional clothes treating device equipped with a steam supply for drying.

[0023] Referring to Korean Patent Publication No. 10-1448632, a conventional clothing treatment device includes a clothing storage section 2 that stores clothing inside a cabinet 1, a water supply pipe 5 that supplies water to the clothing storage section 2, and a steam supply section 4 that is connected to the water supply pipe 5 to receive water and supply steam to the clothing storage section 2.

[0024] The steam supply unit 4 includes a heater 6 for heating water to generate steam. As a result, the conventional laundry processing device can use the steam supply unit 4 to heat water and generate steam during the washing and drying processes. By injecting the steam into the interior of the clothing storage section 2 through section 4, the temperature inside the clothing storage section 2 is raised, thereby increasing the washing or drying efficiency, or removing wrinkles or sterilizing the clothing.

[0025] However, since conventional clothing treatment devices such as washing machines or dryers are designed to treat wet clothing, there is no need to generate a large amount of steam inside the clothing storage section 2 to increase the moisture content of dry clothing, as is the case with clothing management machines.

[0026] Therefore, the conventional clothing treatment device shown in FIG. 2 does not need to be equipped with a large-capacity heater 6, as is the case with clothing care machines.

[0027] Of course, in the conventional clothing treatment device, the heater 6 is composed of a first heater 61 and a second heater 62 that can be driven independently of the first heater 61, and is provided to adjust the amount of steam supplied.

[0028] However, conventional clothing treatment devices such as washing machines and dryers perform a dehydration process to remove moisture from damp clothing and a drying process. Therefore, when the clothing storage unit 2 rotates or when the drying process is performed, there is a fundamental limitation in that the heater 6 cannot operate when a heat pump system including a compressor or a heating system including an air heater (hereinafter referred to as the heat supply unit) is operating.

[0029] As a result, even if dry clothes are put into the washing machine and dryer, there is a fundamental limitation in that the heater 6 and the heat supply unit or motor cannot be driven simultaneously to refresh the clothes.

[0030] Furthermore, when a drying process is performed in a clothes treating device such as a washing machine or a dryer, the purpose is to finally dry wet clothes, so even if the heater 6 is heated and supplies steam during the drying process, the heat supply unit will not stop operating until the process is completed once it has started. In this case, not only will the drying performance be rapidly reduced, but the drying process will also be significantly delayed.

[0031] Therefore, the washing machine and dryer have limitations in that there is no possibility or suggestion of a technology for simultaneously driving the heater for generating steam and the compressor, or a technology for stopping the operation of the compressor in order to drive the heater for generating steam after starting the operation of the compressor.

[0032] As a result, conventional clothing treatment devices have limitations in that they are unable to provide technical information on how to simultaneously drive a heater that generates steam and a compressor that generates hot air in a clothing treatment machine, or how to control and apply the heaters when they are installed as dual heaters in a clothing treatment machine that treats dry clothing.

[0033] Furthermore, conventional clothing processing devices have the problem that they are unable to provide any standards for determining the specifications of the heater that generates steam or any control method for driving the heater and compressor in cooperation with each other. Summary of the Invention [Problem to be solved by the invention]

[0034] The present invention aims to solve the problem of providing a standard for optimally determining the specifications of a system having multiple heaters that generate steam, some of which are driven simultaneously with a compressor.

[0035] The present invention uses water that each heater uses below the allowable value to maintain the internal temperature of the inner case. The problem to be solved is to provide a clothing treatment device that is equipped with specifications to raise the temperature to a target temperature.

[0036] An object of the present invention is to provide a clothing treatment device that optimally determines the specifications of each heater based on the dehumidification amount of an evaporator that condenses moisture.

[0037] SUMMARY OF THE INVENTION An object of the present invention is to provide a clothes treating device that drives a steam heater in a manner that ensures the reliability of a compressor. [Means for solving the problem]

[0038] In order to solve the above-mentioned problems, the present invention optimally determines the specifications of the first heater and the second heater that supply steam to the inside of the inner case where clothes are hung.

[0039] For example, the first heater is configured (or set) to generate a steam amount greater than the dehumidification amount of the evaporator, and the second heater is configured to generate a steam amount equal to or less than the dehumidification amount of the evaporator.

[0040] The first heater is configured so that the average steam generation rate per minute is greater than the average dehumidification rate per minute of the evaporator, and the second heater is configured so that the average steam generation rate per minute is equal to or less than the average dehumidification rate per minute of the evaporator.

[0041] The first heater is provided so that its maximum steam generation rate is greater than the maximum dehumidification rate of the evaporator, and the second heater is provided so that its maximum steam generation rate is equal to or less than the maximum dehumidification rate of the evaporator.

[0042] When the compressor and the first heater are simultaneously driven for a predetermined time or longer, the humidity inside the inner case increases.

[0043] When the compressor and the second heater are simultaneously driven for a predetermined time or longer, the internal humidity of the inner case is maintained or decreased.

[0044] When the compressor, the first heater, and the second heater are simultaneously driven for a predetermined time or longer, the humidity inside the inner case increases.

[0045] The average steam generation amount of the second heater is set to be smaller than the average dehumidification amount of the evaporator.

[0046] The first heater or the second heater is provided so that the amount of steam generated in the basic course corresponds to 80 to 120% of the dehumidification amount of the evaporator.

[0047] The first heater or the second heater is provided so that the amount of steam generated in the strong course corresponds to 130 to 150% of the dehumidification amount of the evaporator.

[0048] The second heater is set to generate a smaller amount of steam than the first heater.

[0049] The control unit drives either the first heater or the second heater intermittently and repeatedly when the compressor is driven in at least a portion of a course.

[0050] The heat supply unit detects the temperature of the refrigerant discharged from the compressor or the condenser. Includes sensors.

[0051] The control unit intermittently and repeatedly drives the first heater or the second heater when the temperature of the refrigerant flowing into or discharged from the compressor reaches a limit temperature while the first heater or the second heater and the compressor are simultaneously driven.

[0052] The clothing treatment device of the present invention further includes a temperature sensor for detecting the temperature inside the inner case or the temperature of the air flowing into the circulation duct.

[0053] When the temperature reaches a target temperature while the first heater or the second heater and the compressor are simultaneously driven, the control unit intermittently and repeatedly drives the first heater or the second heater.

[0054] When the first heater or the second heater is driven intermittently, the driving time is set to be longer than the driving stop time.

[0055] On the other hand, the second heater, which is set to generate less steam than the first heater, is set to increase the internal temperature of the inner case to at least a target temperature.

[0056] The second heater is configured to raise the internal temperature of the inner case to at least the target temperature before the delay time elapses.

[0057] The second heater is set to a specification that uses water at a level not exceeding an allowable value to raise the internal temperature of the inner case to the target temperature.

[0058] The driving power of the second heater is set to between 450W and 700W.

[0059] The driving power of the first heater is set to between 800W and 1100W. [Effects of the Invention]

[0060] The present invention has the effect of providing a standard for optimally determining the specifications of a plurality of heaters that generate steam, while some of the heaters and the compressor are driven simultaneously.

[0061] The present invention has the advantage that each heater can be provided with specifications that use water below the allowable value to raise the internal temperature of the inner case to a target temperature.

[0062] The present invention has the effect of optimally determining the specifications of each heater based on the dehumidification amount of the evaporator that condenses moisture.

[0063] The present invention has the effect of driving a steam heater in a manner that ensures the reliability of the compressor. [Brief explanation of the drawings]

[0065] FIG. 3 shows the appearance of the clothing treatment device 1 of the present invention.

[0066] Referring to FIG. 3( a ), the clothing treating device of the present invention includes a cabinet 100 that forms the exterior, and a door 400 that is rotatably coupled to the cabinet 100 .

[0067] The door 400 includes a main body 410 that forms the front face of the cabinet 100, and an installation body 420 that extends from one side of the main body 410 and has a display that displays information about the laundry treatment device.

[0068] The installation body 420 is provided to form a step 430 from the main body 410 toward the rear of the cabinet 100 .

[0069] Meanwhile, at least a portion of the installation body 420 is disposed so as to overlap the rear of the main body 410 in the front-rear direction, so that the step 430 serves as a handle.

[0070] The installation body 420 may be made of a different material or color from the main body 410. The installation body 420 may be made of a translucent material that transmits light emitted from the display.

[0071] 3(b), an inner case 200 having a storage space 220 for storing clothes is provided inside the cabinet 100. The inner case 200 has an opening 210 at the front for allowing clothes to enter and exit, and the opening 210 is closed by the door 400.

[0072] The inner case 200 is made of a plastic resin, and is made of a reinforced plastic resin that is not deformed by air at a temperature higher than room temperature or heated air (hereinafter referred to as hot air), steam, or moisture.

[0073] The inner case 200 has a height greater than a width, so that the clothes can be accommodated in the accommodation space 220 without being folded or wrinkled.

[0074] The clothing disposal device 1 of the present invention includes a moving hanger 1000 for hanging clothing in the storage space 220 of the inner case 200.

[0075] The moving hanger 100 is provided as a simple hanging part that is seated on the upper part of the inner case 200 and is provided to fix the clothes in a floating state inside the receiving space 220.

[0076] Alternatively, the moving hanger 1000 is mounted on the upper surface of the inner case 200 to swing the clothes.

[0077] The moving hanger 1000 is provided to move back and forth or rotate back and forth on the upper part of the inner case 200. As a result, the clothes hung on the moving hanger 100 are swung in the receiving space 220 to remove foreign matter and are effectively exposed to the supplied steam or hot air.

[0078] The detailed structure and function of the moving hanger 1000 will be described later.

[0079] The door 400 is provided on its inner surface with a pressure member 520 for applying pressure to the clothes.

[0080] The pressure unit 520 includes a support unit 522 fixed to the inner surface of the door 400 and supporting one side of the garment, and a compression unit 521 that applies pressure to the garment supported by the support unit 522 .

[0081] The pressing portion 521 is provided to move toward or away from the support portion 522. For example, the pressing portion 521 is provided on the support portion 522 or the inner surface of the door 400 to be rotatable.

[0082] As a result, the compression part 521 and the support part 522 can pressurize both sides of the clothing, remove wrinkles from the clothing, and create the desired creases.

[0083] The clothing treatment device of the present invention includes a machine room 300 in which various devices are installed that supply one or more of hot air or steam to the storage space 220, or absorb the air outside the cabinet 100, purify or dehumidify it, and then discharge it.

[0084] A control unit for controlling the clothing treatment device is installed inside the machine room 300. Of course, the control unit may be installed inside the door 400.

[0085] The control unit is provided as a PCB that controls one or more of the electrical components of the clothing treatment device of the present invention and performs any course of treatment of the clothing.

[0086] The machine chamber 300 is separated or partitioned from the inner case 200, but is provided to communicate with the inner case 200.

[0087] The machine chamber 300 is disposed below the inner case 200. As a result, hot air and steam with low specific gravity are supplied to the inner case 200, and the hot air and steam are naturally supplied to the clothes.

[0088] The machine room 300 includes a heat supply unit 340 that supplies hot air to the inside of the inner case 200. The heat supply unit 340 may be implemented as a heat pump system or as a heater that directly heats air with electrical energy.

[0089] When the heat supply unit 340 is provided as a heat pump system, it is configured to dehumidify and heat the air discharged from the inner case 200 again and supply the air to the inner case 200. The detailed structure will be described later.

[0090] The machine chamber 300 includes a steam supplier 800 for supplying steam to the inside of the inner case 200. The steam supplier 800 is configured to directly supply steam to the inside of the inner case 200. A detailed structure will be described later.

[0091] For this purpose, the inner case 200 has a plurality of through holes 230 penetrating one surface thereof and communicating with the machine chamber 300 .

[0092] Air in the receiving space 220 is supplied to the machine room 300 through the through-holes 230, and at least one of hot air and steam generated from the machine room 300 is supplied to the receiving space 200.

[0093] The through-holes 230 include an inlet hole 231 that penetrates the lower surface of the inner case 200 to allow the air inside the inner case 200 to flow into the machine chamber 300, and an outlet hole 232 that is spaced apart from the inlet hole 231 and penetrates the lower surface of the inner case 200 to discharge the hot air generated from the machine chamber 300 into the inside of the inner case 200.

[0094] The exhaust hole 232 is disposed closer to the rear side of the lower surface of the inner case 200 than the front side or the door 400 .

[0095] The exhaust hole 232 is disposed at an angle to the ground between the lower surface or rear surface of the inner case 200. The exhaust hole 232 is provided to face the moving hanger 1000, and guides the hot air to be supplied toward the clothes.

[0096] The inlet hole 231 is disposed in the lower surface of the inner case 200 in front of the rear surface or closer to the door 400 .

[0097] The inlet hole 231 is disposed farthest from the outlet hole 232 to prevent the air discharged from the outlet hole 232 from reaching the clothes and being immediately absorbed into the inlet hole 231 .

[0098] The through-hole 230 further includes a steam hole 233 that penetrates the lower part of the inner case 200 and introduces the steam generated from the steam supply part 800 into the inner case 200 .

[0099] The steam hole 233 is disposed closer to the discharge hole 232 than the inlet hole 231. For example, the steam hole 233 is disposed on one side of the discharge hole 232.

[0100] Meanwhile, the machine room 300 further includes a water supply tub 30 for supplying water to the steam supply unit 800, and a drain tub 40 for collecting condensed water condensed in the heat supply unit 340.

[0101] The water supply tub 30 and the drainage tub 40 are detachably provided in front of the machine chamber 300. This allows the clothing treatment device 1 of the present invention to be freely installed without being limited to a water supply source or a drainage source.

[0102] Meanwhile, the machine room 300 further includes a drawer 50 that can be accessed from the front and has another storage space. For example, the drawer 50 may accommodate a steam generator or an iron.

[0103] FIG. 4 shows the structure of the machine chamber of the clothes treating device of the present invention.

[0104] FIG. 4(a) is a view of the machine room 300 as seen from the front, and FIG. 4(b) is a view of the machine room 300 as seen from the rear.

[0105] Inside the machine chamber 300, there are arranged components for supplying hot air to the clothing treatment space, circulating air inside the clothing treatment space, supplying steam to the clothing treatment space, or purifying the air outside the cabinet.

[0106] The machine room 300 includes a base 310 that provides a space for supporting or installing various devices. The base 310 provides an area where the various devices are installed.

[0107] The base part 310 is provided with a circulation duct 320 through which air introduced from the outside of the inner case 200 or the cabinet 100 moves.

[0108] The circulation duct 320 is provided in the form of a case with an open top, and some components of the heat supply unit 340 are provided inside.

[0109] When the heat supply unit 340 is provided as a heat pump system, the circulation duct 320 contains heat exchangers 341 and 343, which will be described later, and a compressor 342 that supplies high-temperature and high-pressure refrigerant to the heat exchangers.

[0110] The heat exchangers 341 and 343 are housed inside the circulation duct 320 and can cool and dehumidify the air flowing through the circulation duct 320, and can also heat the air to generate hot air.

[0111] When the circulation duct 320 is provided to draw air from the outside of the cabinet 100, an outside air duct 370 for drawing in outside air is provided in front of the circulation duct 320.

[0112] The circulation duct 320 is provided to communicate with the outside air duct 370 and is provided to selectively draw in outside air.

[0113] The water supply bucket and the drain bucket are detachably connected to the front of the circulation duct 320. The water supply bucket 30 and the drain bucket 40 are seated on the upper part of the outside air duct 370.

[0114] The circulation duct 320 may be coupled to the base 310 or may be integral with the base 310. For example, the base 310 and the circulation duct 320 may be manufactured by injection molding.

[0115] The machine room 300 includes a base cover 360 that is provided to communicate the circulation duct 320 and the inlet hole 231 .

[0116] The base cover 360 is coupled to an upper portion of the circulation duct 320 to guide the air drawn in through the inlet 231 into the circulation duct 320 .

[0117] The base cover 360 covers the upper surface of the circulation duct 320 to prevent the air inside the circulation duct 320 from being discharged to the outside. The lower part of the base cover 360 and the upper surface of the circulation duct 320 form one surface of the flow path of the circulation duct 320.

[0118] The base cover 360 includes an inlet portion 362 connecting the inlet hole 231 and the circulation duct 320. The inlet portion 362 has a duct shape and serves as an intake duct for transferring air inside the inner case 200 to the circulation duct 320.

[0119] The machine chamber 300 is provided with a steam supply unit 800 connected to the water supply tub 30, which receives water, generates steam, and supplies the steam to the inner case 200. The steam supply unit 800 is seated on the upper part of the base cover 360.

[0120] The steam supply unit 800 is disposed outside the circulation duct 320. This prevents the steam supply unit 800 from interfering with the movement of air flowing through the circulation duct 320 or heating the air.

[0121] In addition, the steam supply unit 800 is disposed at a distance from the inlet unit 362. For example, the steam supply unit 800 is disposed rearward of the inlet unit 362.

[0122] The machine room 300 includes a fan installation unit 350 that communicates the circulation duct 320 with the inner case 200. The fan installation unit 350 includes a blower fan 353 that provides power to move air in one direction inside the circulation duct 320, and a fan housing 351 that houses the blower fan 353 and is connected to or extended from the circulation duct 320.

[0123] The fan installation unit 350 includes an exhaust duct 352 that communicates the circulation duct 320 with the exhaust hole 232 .

[0124] The exhaust duct 352 extends from the fan housing 351 toward the exhaust hole 232 with a cross section corresponding to the area of ​​the exhaust hole 232 .

[0125] As a result, the air inside the inner case 200 is introduced through the base cover 360 , passes through the circulation duct 320 , and is then supplied back into the inner case 200 through the fan installation part 350 .

[0126] Meanwhile, the base part 310 includes a compressor installation part 313 in which the compressor 342 is installed to supply refrigerant to the heat exchangers 341 and 343. The compressor installation part 313 is disposed outside the circulation duct 320.

[0127] The base unit 310 is also provided with the control unit 700 that controls the clothing treatment device of the present invention.

[0128] The base portion 310 is provided with a base portion 310, and the control portion 700 is inserted into the lower portion of the circulation duct 320. A control unit installation section 312 is provided to form a space where the control unit is installed.

[0129] The control unit 700 is provided to control all electronically controlled electrical components such as the compressor 342, the steam supply unit 800, and the blower fan 353.

[0130] Since the control unit 700 is inserted into and supported by the base unit 310, vibrations generated from the moving hanger 1000 or the clothes are blocked from being transmitted to the control unit 700 or are attenuated and transmitted to the control unit 700.

[0131] In addition, the control unit 700 is installed on the base unit 310, and is closely spaced from all the electrical components installed in the machine room 300, thereby preventing noise or control errors from occurring.

[0132] In the clothing treatment device 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. Therefore, the circulation duct 320 is provided in the form of a straight duct 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 is minimized.

[0133] The circulation duct 320, the outside air duct 370, the steam supply unit 800, the control unit 700, and the heat supply unit 340 are all provided on the base unit 310, so that the base unit 310 is provided as a single module. As a result, the base unit 310 can be moved forward or backward in the machine room 300, and most of the electrical components can be easily installed and maintained.

[0134] FIG. 5 shows the base structure of the machine chamber of the clothes treating device of the present invention.

[0135] FIG. 5(a) is a perspective view of the base portion 310 as seen from the front, and FIGS. 5(b) and 5(c) are perspective views of the base portion 310 as seen from the rear.

[0136] The base 310 is mounted on a base plate that forms the lower surface of the laundry treatment device. The base 310 itself forms the lower surface of the laundry treatment device.

[0137] The base 310 includes a base bottom 311 that forms a support surface. The base bottom 311 forms the lower surface of the laundry treatment device. The base bottom 311 is also provided on the upper surface of the bottom surface of the cabinet 100 that forms the lower surface of the laundry treatment device.

[0138] The base part 310 is integrally provided with the circulation duct 320, which forms at least a part of a flow path through which air moves. The circulation duct 320 is formed to extend from the bottom part 311 of the base to an upper part.

[0139] The circulation duct 320 includes a duct body 321 extending from the base bottom 311 to form a flow path, a heat exchanger installation section 3212 providing space for an evaporator 341 or a condenser 343 to be installed inside the duct body 321, and an air discharge section 323 provided at the rear of the duct body 321 and through which air from the duct body 321 is discharged.

[0140] The air discharge part 323 has a pipe shape and extends rearward from the duct body 321. The diameter of the air discharge part 323 is smaller than the width of the duct body 321.

[0141] The air discharge part 323 is connected to the fan housing 350. The air discharged from the air discharge part 323 is guided into the inside of the inner case 200 through the fan housing 350.

[0142] The circulation duct 320 includes an outside air intake portion 322 formed by penetrating the front surface of a duct body 321 .

[0143] The outside air intake part 322 is provided to communicate with the outside air duct 370. The outside air duct 370 is seated and supported in front of the outside air intake part 322.

[0144] The circulation duct 320 includes a damper that opens and closes the outside air intake portion 322. The damper allows or blocks the outside air from flowing into the circulation duct 320 depending on whether the damper is open or closed.

[0145] The base part 310 includes a compressor installation part 312 that provides a space for installing the compressor 342. The compressor installation part 312 is formed on one side of the base bottom part 311 and is integral with the base bottom part 311.

[0146] The compressor installation part 312 has a protrusion formed thereon to support the compressor 342. The compressor installation part 312 is disposed offset toward the rear of the base part 310. The compressor installation part 312 is disposed to overlap at least a portion of the air discharge part 323 in the width direction.

[0147] The compressor installation part 312 is provided with a buffer member for reducing vibration transmitted from the compressor 342. The buffer member is fixed to the protrusion.

[0148] The base 310 includes a control unit installation part 313 on which the control unit 700 is installed. The control unit installation part 313 is formed between the base bottom 311 and the circulation duct 320. The control unit installation part 313 is formed between the base bottom 311 and the bottom surface of the circulation duct 320. The control unit installation part 313 is provided in the shape of a duct at the bottom of the circulation duct 320, with either the front or rear ends being open.

[0149] FIG. 6 shows the structure of the circulation duct of the laundry treatment device of the present invention.

[0150] The circulation duct 320 extends from the bottom to the top of the base, forming a flow path for air to flow through. The circulation duct 320 includes a heat exchanger installation portion 3212 that provides a space for installing an evaporator 341 and a condenser 342. The heat exchanger installation portion 3212 is provided inside the duct body 321.

[0151] The duct body 321 has an open upper surface, through which a condenser 343 and an evaporator 341 are inserted.

[0152] The opening of the duct body 321 is covered by the base cover 360 , and the base cover 360 and the duct body 321 form a flow path of the circulation flow path 320 .

[0153] The front surface of the duct body 321 is spaced rearward from the front end of the base bottom 311 .

[0154] Thus, the base bottom 311 secures a support surface 3111 on which at least one of the water supply tub 30, the drain tub 40 and the outside air duct 370 is provided and supported.

[0155] Meanwhile, the heat supply unit 340 includes an evaporator 341 installed inside the circulation duct 320 and configured as a heat exchanger for cooling and dehumidifying the air flowing into the circulation duct 320, a condenser 343 installed as a heat exchanger for heating the air passing through the evaporator 341 to form hot air, a compressor 342 installed outside the circulation duct 320 and supplying a refrigerant to the condenser 343 for heat exchange with the air, and an expansion valve 344 for expanding and cooling the refrigerant passing through the condenser 343.

[0156] Meanwhile, since the duct body 321 is integrally formed with the base part 310, the height of the heat exchanger installation part 3212 can be further secured, and the heights of the condenser 343 and the evaporator 341 can also be increased. As a result, the widths of the condenser 343 and the evaporator 341 in the front-rear direction can be reduced, and the number of refrigerant pipes passing through the condenser and the evaporator can be reduced. This has the effect of reducing the flow loss of air passing through the condenser and the evaporator.

[0157] Meanwhile, the sum of the lengths of the evaporator 341 and the condenser 343 is set to be shorter than the length of the heat exchanger installation portion 3212. Thus, the length of the heat exchanger installation portion 3212 in the front-rear direction is set to be equal to or shorter than half the length of the duct body 321.

[0158] Therefore, since the heat exchanger installation part 3212 is sufficiently separated from the outside air intake part 322, a sufficient space can be secured inside the circulation duct 320 for the outside air and the air inside the inner case 200 to flow in.

[0159] Meanwhile, the inside of the duct body 321 includes an installation partition 3211 that separates the heat exchanger installation portion 3212 from the outside of the heat exchanger base portion 3212. The installation partition 3211 protrudes from the side of the duct body 321 to support the front of the evaporator 341.

[0160] In addition, the duct body 321 is expanded in width based on the installation partition wall 3211 and extends rearward.

[0161] As a result, the width of the heat exchanger installation portion 3212 is greater than half the width of the base portion 310. Also, the width of the circulation duct 320 is greater than half the width of the base portion 310.

[0162] The width of the condenser 343 and the width of the evaporator 341 are also greater than half the overall width of the base part 310. As described above, when the widths of the condenser 343 and the evaporator 341 are secured, there is an effect that a sufficient heat exchange capacity can be secured.

[0163] In addition, the fan housing 350 is disposed to overlap the condenser 343 or the evaporator 341 in the front-rear direction. Therefore, the air that has passed through the evaporator 341 and the condenser 343 flows into the fan housing 350 without bending its flow path. That is, the air that has flowed into the circulation duct 320 does not bend its flow path while traveling to the fan housing, which minimizes flow loss. The clothing treatment device of the present invention further includes a temperature sensor S1 that detects the temperature inside the inner case 200 or the temperature of the air that flows from the inside of the inner case 200 into the circulation duct 320, and a refrigerant sensor S2 that detects the temperature of the refrigerant circulating through the heat supply unit.

[0164] The temperature sensor S1 is provided on the inner wall of the circulation duct 320, and the refrigerant sensor S2 is provided on the discharge side of the compressor 342.

[0165] FIG. 7 shows the structure of the air discharge section 323 of the laundry treatment device of the present invention.

[0166] The base portion 310 includes an air outlet portion 323 that discharges treated air toward the fan housing.

[0167] The air discharge part 323 is provided to communicate the inside of the circulation duct 320 or the duct body 321 with the fan housing 350. The air discharge part 323 has a bell mouth shape, which can reduce air flow loss and improve air circulation efficiency.

[0168] The air exhaust pipe 3232 of the air exhaust part 323 is provided in a pipe shape, and based on the parting line 3233, during the mold removal process, the mold placed in front of the parting line 3233 is pulled forward, and the mold placed behind the parting line 3233 is pulled backward.

[0169] The fan installation part 350 is coupled to and supported by the air discharge pipe 3232. The fan housing 351 has a coupling hole coupled to the outer circumferential surface of the air discharge pipe 3232, and the blower fan 353 is disposed in the coupling hole.

[0170] The fan housing 351 includes an exhaust duct 352 extending from the outer circumferential surface or outside of the blower fan 353 to the exhaust hole 232 .

[0171] The fan housing 351 and the exhaust duct 352 house the blower fan 353 therein and form a flow path through which air moves.

[0172] A motor for rotating the blower fan 353 is coupled to and supported on the outside of the fan housing 351 .

[0173] FIG. 8 shows the structure of the base cover of the clothing treatment device of the present invention.

[0174] The base cover 360 is coupled to an upper surface of the circulation duct 320 to prevent the inside of the circulation duct 320 from being exposed.

[0175] The base cover 360 is coupled to the upper surface of the circulation duct 320 and includes an inlet body 361 that connects the inner case 200 to the circulation duct 320, and a shielding body 363 that extends from the inlet body 361 and shields the circulation duct 320.

[0176] The inflow body 361 has a duct shape and is provided to communicate the inflow hole 231 of the inner case with the inside of the circulation duct 320. The inflow body 361 is provided to protrude upward from the shielding body 363.

[0177] The inflow body 361 is disposed forward of the evaporator 341 and the partition wall 3211 so as not to face the evaporator 341 and the condenser 343 .

[0178] The inflow body 361 serves as an inflow duct that transfers the air in the inner case 200 to the circulation duct 320 .

[0179] The inlet body 361 has an inlet portion 362 therein through which the air of the inner case 200 passes.

[0180] Specifically, the base cover 360 includes a first rib 362a extending along the width direction of the inlet body 361 and a second rib 362b spaced rearward from the first rib 362a and extending along the width direction of the inlet body 361.

[0181] The first rib 362a and the second rib 362b are arranged side by side. The first rib 362a and the second rib 362b are arranged in a plate shape extending vertically, and their heights correspond to the height of the inlet body 361.

[0182] The front corner of the inlet body 361 and the first rib 362a form a first inlet 3621, the first rib 362a and the second rib 362b form the second inlet 3622, and the second rib 362b and the rear corner of the inlet body 361 form a third inlet 3623.

[0183] The first inlet 3621 and the third inlet 3622 have the same area, and the second inlet 36222 has an area smaller than the areas of the first inlet 3621 and the third inlet 3622.

[0184] The base cover 360 includes a damper part 364 configured to open and close the inlet part 362, and a driver 365 coupled to the damper part 364 and controlling the opening and closing of the damper part 364.

[0185] The damper part 364 includes a first damper part 3641 configured to open and close the first inlet 3621 and a second damper part 3642 configured to open and close the third inlet 3623 .

[0186] The first damper part 3641 is formed in a plate shape having an area corresponding to the first inlet 3621 and is rotatably coupled to both sides of the inlet body 361 inside the first inlet 3621 .

[0187] The second damper part 3642 is provided in a plate shape having an area corresponding to the third inlet 3622 and is rotatably coupled to both sides of the inlet body 361 inside the third inlet 3622 .

[0188] The second inlet 3622 is provided with a blocking filter 366 that allows air to pass through but filters out foreign matter such as fine dust and lint.

[0189] The blocking filter 366 is inserted into the second inlet 3622 and is configured to separate the first inlet 3621 and the third inlet 3623. The blocking filter 366 is disposed to extend from the second inlet 3622 so as to contact the bottom surface of the circulation duct 320.

[0190] The blocking filter 366 is a filter capable of filtering out the moisture, such as a HEPA filter.

[0191] Meanwhile, when the blocking filter 366 is inserted, a blocking member for blocking the second inlet 3622 is further coupled to the second inlet 3622 .

[0192] The driving unit 365 includes a motor that provides power to selectively rotate the first damper unit 364 and the second damper unit 365, and a plurality of gear members that are engaged with the motor to rotate and selectively rotate the first damper unit 364 and the second damper unit 365. .

[0193] The first inlet 3611 and the third inlet 3623 are selectively opened by the driving part 365 .

[0194] By the driving part 365, the air stored inside the inner case 200 may be flowed into the inside of the circulation duct 320 along the first inlet 3621, and may be flowed into the inside of the circulation duct 320 along the third inlet 3623.

[0195] Of course, the driving unit 365 controls the first damper 3641 and the second damper 3642 to open both the first inlet 3611 and the third inlet 3623, and controls the first damper 3641 and the second damper 3642 to close both the first inlet 3611 and the third inlet 3623.

[0196] The driving unit 365 may have any structure as long as it rotates the first damper 3641 and the second damper 3642. For example, it may be provided as 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 driving gear.

[0197] The base cover 360 includes a shielding body 363 extending from the inlet body 361 and shielding the evaporator 341 and the condenser 343. The shielding body 363 has a plate shape.

[0198] The base cover 360 is detachably connected to the upper surface of the circulation duct 320 by an inlet hook 3612 extending from the lower surface of the inlet body 361 .

[0199] The circulation duct 320 has a coupling portion that is detachably coupled to the inlet hook 3612 .

[0200] FIG. 9 is a diagram showing the installation structure of the steam supply unit.

[0201] The steam supply unit 800 is seated and supported on the base cover 360 .

[0202] The steam supply unit 800 is seated on the base cover 360 and includes a steam generator 810 that stores water for generating the steam.

[0203] The steam supply 800 further includes a mounting bracket 870 that secures the steam generator 810 to the base cover 360 .

[0204] The mounting bracket 870 is coupled to the base cover 360 to secure the steam generator 810 in place.

[0205] The installation bracket 870 includes a lower panel 871 that supports the lower surface of the steam generator 810 , and side panels 872 that support both side surfaces of the steam generator 810 on the lower panel 871 .

[0206] The mounting bracket 870 further includes one or more securing clips 873 extending from the side panel 872 to prevent the steam generator 810 from detaching.

[0207] The fixing clip 873 is detachably provided on the top or side of the steam generator 810. can be.

[0208] The compressor 342 is disposed below the steam supply unit 800 .

[0209] The installation bracket 870 is provided to block heat generated from the compressor or heat generated from the refrigerant compressed in the compressor from being transferred to the steam supplier 800 .

[0210] The mounting bracket 870 can also prevent the fire from spreading to the steam supply unit 800 if a fire occurs in the compressor 342 .

[0211] Meanwhile, the base cover 360 includes a fastening part 3631 provided on the shielding body 363 and detachably coupled to the steam supply part 800. The fastening part 3631 is provided in a structure that allows it to be detachably coupled to a protrusion protruding from the lower part of the steam generator 810.

[0212] Therefore, even if a large amount of water is contained inside the steam generator 810, the steam generator 810 is stably seated on the base cover 360.

[0213] In addition, since the steam generator 810 is disposed above the circulation duct 320 and the distance to the inner case 200 is further shortened, condensation of the steam generated from the steam generator 810 before it reaches the inner case 200 can be minimized.

[0214] FIG. 10 shows the detailed structure of the steam supply section.

[0215] Referring to FIG. 10(a), the steam supply unit 800 includes a steam generator 810 that stores water for generating steam, and a steam heater 840 that is housed in the steam generator 810 and heats the water to generate steam.

[0216] The steam generator 810 is provided in the form of a case that forms a space for accommodating the steam heater 840 .

[0217] For example, the steam generator 810 is provided in the form of a case with an open top, and is provided to accommodate the steam heater 840 therein.

[0218] The steam supply unit 800 further includes a case cover 820 coupled to the steam generator 810 to prevent the steam heater 840 from being exposed to the outside and to prevent the water from leaking out.

[0219] The case cover 820 is provided with a water level sensor 850 for detecting the water level in the steam generator 810 and a steam sensor 860 for detecting the temperature inside the steam generator 810 or detecting whether steam is generated inside the steam generator 810.

[0220] Referring to FIG. 10( b ), the steam generator 810 includes a case body 811 that stores the water and provides a space for accommodating a steam heater 840 .

[0221] The case body 811 has an open top, and various components can be easily installed inside the case body 811 .

[0222] The case body 811 has one side penetrated and includes a heater insertion hole 8111 into which the heater 840 is inserted or pulled out.

[0223] The case body 811 has a water return pipe 814 therein to which water for generating steam is supplied.

[0224] The water return pipe 814 may be provided to discharge water stored inside the case body 811 to the outside.

[0225] The water return pipe 814 is maintained in a closed state by a shielding plug 8141 so that it is opened only when residual water inside the steam generator 810 is removed, and includes a shielding clip 8142 that maintains a state in which the shielding plug 8141 is attached to the water return pipe 814 so that the shielding plug 8141 is prevented from being accidentally separated.

[0226] Thus, when the steam generator 800 is repaired or when the steam generator 800 is to be prevented from freezing and breaking, water inside the steam generator 800 is discharged through the water return pipe 814 .

[0227] Of course, the water return pipe 814 is provided to supply water to the water supply tub 30. The details will be described later.

[0228] Meanwhile, a heater fixing part 830 for supporting or fixing the steam heater 840 is provided inside the case body 811. The heater fixing part 830 includes a fixing clip 831 for fixing the steam heater 840, and a clip fastening member 833 for fixing the support clip 831 to the case body 811.

[0229] The fixing clip 831 is provided to house or surround at least a portion of the steam heater 840 .

[0230] Meanwhile, the steam supply unit 800 is provided with a water supply pipe 815 for supplying water. The water supply pipe 815 is connected to the water supply tub 30 so that water can be supplied.

[0231] The water supply pipe 815 is provided in the case cover 820 or disposed on the top of the steam generator 810. This prevents water from flowing back through the water supply pipe 815.

[0232] The steam supply unit 800 includes a steam pipe 813 that discharges steam generated by the operation of the steam heater 840 to the outside. The steam pipe 813 is also provided on the upper part of the case cover 820, and water is prevented from being discharged into the steam pipe 813.

[0233] The steam pipe 813 is connected to the steam hole 233 of the inner case 200 .

[0234] The case cover 820 is provided with a water level sensor hole 854 in which the water level sensor is installed.

[0235] The water level sensor 850 includes one or more contact protrusions 852 that are inserted into the water level sensor hole 854 and immersed in water to detect the water level, and the contact protrusions 852 are connected to the steam generator 8. 10 , and a sensor body 851 that is coupled to the water level sensor hole 854 or supported by the case cover 820 to maintain a floating state inside the case cover 820 .

[0236] The sensor body 851 is coupled to the case cover 820 via a sensor fastening member 853 .

[0237] Meanwhile, the case cover 820 has an insertion hole 864 in which the steam sensor 860 is installed. The steam sensor 860 includes a detection device 861 that is inserted into the insertion hole 864 and detects whether steam is generated inside the steam generator 810, a support 863 that fixes the detection device 861 to the case cover 820, and a connecting member 862 that connects the support 863 to the case cover 820.

[0238] The detection device 861 is provided as a humidity sensor or a temperature sensor, and detects whether steam is generated inside the steam generator 810.

[0239] Meanwhile, the case cover 820 is provided with a cover hook 821 that extends forward and is coupled to the base cover 860 .

[0240] In addition, a fixing protrusion 822 for fixing the lower part of the inner case 200 or a separate steam discharge part 900 is also provided at the rear of the case cover 820 .

[0241] The steam heater 840 is inserted into the heater insertion hole 8111, accommodated in the steam generator 810, and supplied with power to heat water.

[0242] The steam heater 840 is provided as a sheath heater or the like, and is controlled by the control unit 700 so that it is repeatedly driven and stopped.

[0243] The steam heater 840 includes a first heater 841 supplied with a first power to heat water, and a second heater 842 supplied with a power smaller than the first power to heat water.

[0244] As a result, the second heater 842 is configured to heat less water and produce more steam than the first heater 841.

[0245] The first heater 841 and the second heater 842 are configured to consume a portion of the maximum heater power allowed for the steam heater 840 in the laundry treatment device. That is, when the first heater 841 is configured to consume a portion of the maximum heater power, the second heater 842 is configured to consume the remainder of the maximum heater power.

[0246] For example, if the maximum heater power allowed for the steam heater 840 is 1500 W, the first heater 841 is configured to consume 880 W, and the second heater 842 is configured to consume 600 W. In this way, 20 W may be divided into smaller amounts in consideration of errors, etc.

[0247] Of course, the steam heater 840 may include three or more heaters, for example, 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 are configured to share the maximum amount of heater power.

[0248] Hereinafter, the steam heater 340 is connected to the first heater 841 and the second heater 842. This explanation will be based on what can be provided in 42.

[0249] The first heater 841 and the second heater 842 are formed of U-shaped metal tubes.

[0250] The steam heater 840 includes a heater sealer 843 that fixes the first heater 841 and the second heater 842 and seals the heater through-hole 8111, and includes a terminal part 844 that supplies current to the first heater 841 and the second heater 842.

[0251] The terminal portion 844 includes 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 .

[0252] The first heater 841 and the second heater 842 are disposed at the same height, so that the first heater 841 and the second heater 842 are configured to heat water at the same water level to generate steam.

[0253] Accordingly, the control unit 700 controls the amount of steam generated and the amount of power consumed by using both or selectively the first heater 841 and the second heater 842.

[0254] FIG. 11 is a diagram showing the inside of the steam generator.

[0255] The steam generator 810 has a heating space 817 that stores water therein and accommodates a steam heater 840 .

[0256] The steam generator 810 is supplied with water for generating steam through a water supply hose 8151 connected to the water supply pipe 815 .

[0257] Meanwhile, the steam generated by driving the steam heater 840 in the steam generator 810 is discharged to the outside of the steam supply unit 800 through the steam discharge pipe 813 and the steam hose 8131 .

[0258] The steam hose 8131 is connected to the steam hole 233 of the inner case 200 .

[0259] Meanwhile, the steam generator 810 includes a partition wall 812 that separates the heating space 817 from the water level sensor 850. That is, the partition wall 812 is provided to separate the steam heater 840 from the water level sensor 850, and is disposed on one side of the case body 811.

[0260] The water level sensor 850 is disposed between the separating partition 812 and the inner surface of the case body 811 .

[0261] This prevents the vibrations of the water generated when the water boils from being transmitted to the water level sensor 850, and also prevents the heat generated by the steam heater 840 from being directly transmitted to the water level sensor 850.

[0262] FIG. 12 is a diagram showing a steam supply section provided with the steam heater.

[0263] Referring to FIG. 12(a), the steam sensor 860 detects the temperature of the steam heater 8 40 and is provided to detect the temperature inside the steam generator 810. Thus, the steam sensor 860 detects that steam is generated when the water reaches 100°C or a high temperature.

[0264] The steam heater 840 is supported by the support clip 832, which prevents the steam heater 840 from contacting the bottom surface of the steam generator 810, etc.

[0265] In addition, the upper part is enclosed by the fixing clip 831, which prevents the water level in which the steam heater 840 is placed from fluctuating.

[0266] Referring to FIG. 12(b), the heater sealer 844 of the steam heater 840 includes a first support hole 8441 through which the first heater 841 passes and is supported, and a second support hole 8442 through which the second heater 842 passes and is supported.

[0267] A first length L1 by which the first support hole 8441 is spaced from the bottom surface of the steam generator 810 and a second length L2 by which the second support hole 8442 is spaced from the bottom surface of the steam generator 810 are the same as each other.

[0268] Although the first support hole 8441 and the second support hole 8442 have different diameters, they have the same height.

[0269] As a result, the first heater 841 and the second heater 842 heat the water at the same water level to generate steam.

[0270] FIG. 13 shows in detail the steam supply structure of the clothes treating device of the present invention.

[0271] The steam generated in the steam generator 810 is immediately supplied to the inside of the inner case 200 through the steam pipe 813 .

[0272] However, if steam is immediately supplied into the inner case 200 through the steam pipe 813, the water stored in the steam generator 810 may also be supplied into the inner case 200.

[0273] In addition, the water heated in the steam generator 810 heats the bottom surface of the inner case 200, which may cause thermal damage to the inner case 200.

[0274] To prevent this, the steam supply unit 800 of the present invention further includes a steam nozzle 900 that receives the steam generated from the steam generator 810 and supplies it to the inner case 200 .

[0275] The steam nozzle 900 is disposed apart from the steam generator 810 so that only the steam generated from the steam generator 810 is supplied, and the water stored in the steam generator 810 is not supplied.

[0276] For example, the steam nozzle 900 is disposed above the steam generator 810 and connected to the steam pipe 813. Thus, the steam generated in the steam generator 810 rises due to a difference in density and is supplied to the steam nozzle 900 along the steam pipe 813, and water stored in the steam generator 810 does not flow into the steam pipe 813 or the steam nozzle 900 due to gravity.

[0277] The steam nozzle 900 is disposed between the bottom surface of the inner case 200 and the steam generator 810 and communicates with the steam hole 233 .

[0278] Meanwhile, the steam supply unit 800 of the present invention is provided to receive water from the water supply tub 30 and generate steam.

[0279] For this purpose, the laundry treatment device of the present invention further includes a water supply pump 880 for supplying water stored in the water supply tub 30 to the steam supply unit 800 .

[0280] The steam supply unit 800 further includes a supply pipe 890 that introduces water stored in the water supply tub 30 to the water supply pump 880 .

[0281] The laundry treatment device of the present invention further includes a water supply pipe 815 for introducing water discharged from the water supply pump 880 to the steam supply unit 800. The water supply pipe 815 is provided in the form of a water supply hose 8151 made of rubber.

[0282] As a result, the water supply pump 880 is configured to supply water from a supply pipe 890 connected to the water supply tub 30. Also, the water supply pump 880 is configured to supply and discharge water to the steam supplier 800 through a water supply pipe 881.

[0283] The steam supply unit 800 includes a water supply pump 880 that provides power to supply water stored in the water supply tub 30 to the steam generator 810 .

[0284] The supply pipe 890 is provided as a hose connecting the water supply tub 30 and the water supply pump 880 , and the water supply pipe 881 is provided as a hose connected to the water supply pump 880 .

[0285] Meanwhile, the water supply pipe 815 is provided to directly connect the water supply pump 880 and the steam generator 810. Thus, water supplied from the water supply pump 880 is directly supplied to the steam generator 810 and heated by the steam heater 840 to generate steam. The steam is supplied to the steam nozzle 900 through the steam pipe 813 and transferred to the inner case 200.

[0286] However, as shown in FIG. 15, the water supply pipe 815 is provided to directly connect the water supply pump 880 and the steam nozzle 900 .

[0287] In other words, the laundry treatment device of the present invention is configured to supply water stored in the water supply tub 30 to the steam nozzle 900 rather than to the steam generator 810. Water supplied from the water supply pump 880 is supplied directly to the steam nozzle 900.

[0288] The water supply pump 880 does not have to be directly connected to the steam generator 810. The water supply pump 880 communicates with the steam generator 810 through the steam nozzle 900.

[0289] The water stored in the water supply tub 30 is supplied to the steam nozzle 900 through the water supply pump 880. The water supplied to the steam nozzle 900 is transferred to the steam generator 810.

[0290] The steam nozzle 900 is disposed above the steam generator 810, so that the water supplied to the steam nozzle 900 is automatically supplied to the steam generator 810. .

[0291] As a result, the steam nozzle 900 is configured so that the water stored in the water supply tub 30 is supplied to the steam generator 810 via the water supply pump 880 .

[0292] The steam supply unit 900 further includes a water return pipe 815 connecting the steam nozzle 900 and the steam generator 810. The water return pipe 815 supplies the water, which is supplied to the steam nozzle 900 and temporarily stored therein, to the steam generator 810.

[0293] Therefore, the steam pipe 813 through which steam flows into the steam nozzle 900 and the water return pipe 815 through which water is discharged from the steam nozzle 900 are provided as separate flow paths.

[0294] Therefore, the water supplied from the steam nozzle 900 is prevented from interfering with the movement of the steam supplied from the steam generator 810 .

[0295] Meanwhile, the water return pipe 815 is provided in a U-shape. That is, the height of a portion of the area between the ends of the water return pipe 815 is lower than that of both ends of the water return pipe 815. As a result, a predetermined amount of water accumulates in the water return pipe 815 like a water trap, and steam or water supplied from the steam generator 810 is prevented from re-entering through the water return pipe 815.

[0296] The steam pipe 813 includes a steam hose 8131 that connects the steam nozzle 900 and the steam generator 810. The steam hose 8131 is made of a rubber material.

[0297] The water return pipe 815 is provided separately from the steam pipe 813 and is spaced apart from the steam pipe 813. The water return pipe 815 includes a recovery hose 8151 that connects the steam nozzle 900 and the steam generator 810. The recovery hose 8151 is made of a rubber material.

[0298] The steam generator 810 receives and accommodates water supplied to the steam nozzle 900. Since the steam generator 810 is not directly connected to the water supply pump 880, there is no possibility that the water flowing into the steam generator 810 will flow back to the water supply pump 880.

[0299] In addition, the steam nozzle 900 is disposed above the steam generator 810 and is connected to the steam generator 810 via the water return pipe 815, so that the water supplied to the steam nozzle 900 is 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 does not have the possibility of flowing back to the water supply pump 880.

[0300] As a result, a check valve may be omitted between the water supply pump 800 and the steam nozzle 900 or the steam generator 810. Therefore, the water supply pipe 881 is provided with a single water supply hose. This simplifies the flow path for supplying water to the steam supply unit 900, thereby reducing the possibility of water being filtered out from the flow path.

[0301] Also, a large amount of water is supplied to the steam nozzle 900 at a considerable pressure through the water supply pump 800. As a result, foreign matter or bacteria that has accumulated in the steam nozzle 900 is washed away by the water supplied to the steam nozzle 900 and is washed away into the steam generator 810. Therefore, the steam nozzle 900 is always kept clean. This can prevent the flow of supplied steam from being obstructed.

[0302] Meanwhile, when the steam supplied from the steam nozzle 900 is condensed, the condensed water is returned to the steam generator 810 via the water return pipe 815. That is, the condensed water generated from the steam nozzle 900 is collected in the steam generator 810 in the same direction as the water supplied from the water supply pump 800 and is reused as water for generating the steam. Therefore, the laundry treatment device of the present invention can prevent the water level in the water supply tub 30 from decreasing rapidly, and can also prevent water waste.

[0303] FIG. 14 illustrates the flow path structure of the steam supply of the present invention.

[0304] Water supplied from the water supply pump 880 is supplied to the steam nozzle 900 along the water supply pipe 881 .

[0305] The steam nozzle 900 supplies the supplied water to the steam generator 810 .

[0306] The steam generator 810 is supplied with water via the water return pipe 815 .

[0307] When water is heated by the steam heater 840 in the steam generator 810 to generate steam, the steam is supplied to the steam nozzle 900 along the steam pipe 813 .

[0308] At this time, the water return pipe 815 and the steam pipe 813 are disposed in the steam generator 810 separated from each other.

[0309] The steam condensed in the steam nozzle 900 is re-entered into the steam generator 810 via the water return pipe 815 .

[0310] The steam generator 810 may not have any hoses connected to the outside except for the water return pipe 815 and the steam pipe 813 connected to the steam nozzle 900. That is, since the water supply pump 880 is not directly connected to the steam generator 810, the hoses connecting the water supply pump 800 and the steam generator 810 may be omitted.

[0311] Therefore, the clothing treatment device of the present invention only needs to include the water supply pipe 881, the water return pipe 815, and the steam pipe 813 as steam-related flow paths, which simplifies the structure of the flow paths.

[0312] Also, the steam nozzle 900 is disposed above the steam generator 810. Therefore, the water supplied to the steam nozzle 900 is entirely guided to the steam generator 810 without a separate check valve.

[0313] Therefore, when the 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 is led to the steam generator 810, thereby preventing the possibility of water flowing back from the steam nozzle 900 to the water supply pump 880.

[0314] Therefore, the check valve between the water supply pump 880 and the steam nozzle 900 may be omitted.

[0315] In addition, since the check valve does not need to be provided in the water supply pipe 880, there is no need to provide a plurality of water supply pipes 880, and the water supply pipes 880 can be provided as a single hose. Not only is this simplified, but the flowpath is also easier to install and repair, further reducing the chance of drainage.

[0316] FIG. 15 shows the flow path structure of the steam nozzle.

[0317] The steam nozzle 900 includes a supply container 910 that receives steam from the steam case 810 or water supplied from the water supply pump 880 and accommodates the steam.

[0318] The supply container 910 is provided in the form of a case having an internal space for receiving and storing water or steam.

[0319] The water supply pipe 881 is 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 is connected to the side surface of the supply container 910. This prevents water supplied to the supply container 910 from flowing back into the water supply pipe 881.

[0320] The water supply pipe 881 is connected to the supply vessel 910 at a location higher than the water return pipe 815. For example, one end of the water return pipe 815 is connected to the bottom of the supply vessel 910, and the other end is connected to the steam generator 810. Thus, water supplied to the water supply pipe 881 automatically flows into the water return pipe 815.

[0321] The water return pipe 815 is U-shaped so as to accommodate a predetermined amount of water therein.

[0322] Meanwhile, the water return pipe 815 is disposed adjacent to the water supply pipe 881. Therefore, the water supplied to the water supply pipe 811 does not remain in the supply container 810 but quickly flows into the steam case 810.

[0323] Meanwhile, one end of the steam pipe 813 is connected to the lower part of the supply container 910, and the other end is connected to the upper end of the steam generator 810 or the steam cover 820. Thus, the steam generated from the steam generator 810 is automatically supplied to the supply container 910 according to the difference in density.

[0324] The steam pipe 813 is connected to the supply vessel 910 at a position higher than the water return pipe 815. In addition, the steam pipe 813 is disposed farther away from the water supply pipe 881 than the water return pipe 815.

[0325] As a result, the water supplied to the supply vessel 910 does not flow back to the steam pipe 813 and is supplied to the water return pipe 815 in greater amount.

[0326] The steam wand 813 is coupled to the bottom of the supply vessel 910 .

[0327] The bottom of the supply vessel 910 is lower where the water return pipe 815 is connected and higher where the steam pipe 813 is connected. For this purpose, the bottom of the supply vessel 910 has a step or is inclined.

[0328] The steam nozzle 900 further includes a container cover 920 coupled to the top of the supply container 910. The container cover 920 includes a steam injection hole 923 formed through the top of the container cover 920. The steam injection hole 923 is formed to communicate with the interior of the inner case 200.

[0329] The supply container 910 has a box shape with an open top, and the container cover 920 is provided to cover the top of the supply container 910 .

[0330] The steam supplied through the steam pipe 813 is discharged through the steam injection holes 923 and supplied to the inside of the inner case 200 .

[0331] The steam pipe 813 is disposed between the steam injection hole 932 and the inner surface of the supply container 910. The steam injection hole 932 is disposed between the water supply pipe 881 and the steam pipe 813, and between the water return pipe 815 and the steam pipe 813. As a result, steam that is not discharged to the steam injection hole 932 and is condensed does not remain inside the supply container 910, but is discharged to the water return pipe 815.

[0332] The steam injection hole 932 is disposed at the center of the width direction of the container cover 920 .

[0333] The container cover 920 is coupled to the supply container 910 by a method such as hook coupling, so that a separate fastening member for coupling the container cover 920 to the supply container 910 may be omitted.

[0334] Meanwhile, the supply container 910 has an open top, which is advantageous for installing various structures inside, and the container cover 920 is advantageous for installing various structures below.

[0335] With respect to the steam injection hole 932 , the water supply pipe 881 and the water return pipe 815 are disposed on one side of the supply vessel 910 , and the steam pipe 813 is disposed on the other side of the supply vessel 910 .

[0336] That is, the water supply pipe 881 and the water return pipe 815 are disposed adjacent to each other, and the steam pipe 813 is disposed farther away from the water supply pipe 881 than the water return pipe 815 is.

[0337] As a result, water moving to the water supply pipe 881 is supplied to the supply container 910 along direction I. The water supplied to the supply container 910 is immediately discharged to the water return pipe 815 along direction II and supplied to the steam generator 810. Steam supplied from the steam pipe 813 is supplied to the supply container 910 along direction III and discharged to the steam injection hole 932, and the condensed water is discharged to the water return pipe 815 along direction II and re-supplied to the steam generator 810.

[0338] An embodiment of the moving hanger 1000 will now be described in detail.

[0339] The moving hanger 1000 is provided to move linearly back and forth inside the inner case 200. Thus, the clothes are moved back and forth directly inside the inner case 200 and shaken.

[0340] The moving hanger 1000 is configured to periodically shake the clothes at various frequencies.

[0341] For example, the moving hanger 1000 may be provided with a structure similar to that disclosed in Korean Patent Publication No. 10-1285890.

[0342] The moving hanger 1000 also holds the clothes inside the inner case. The clothes are provided to be rotated back and forth to shake the clothes.

[0343] That is, in the clothing disposal device of the present invention, the moving hanger 1000 may have any structure as long as it can shake the clothing in the inner case.

[0344] The structure of the moving hanger 1000 that rotates the clothes back and forth will be described below.

[0345] FIG. 16 shows the structure of the upper part of the inner case of the clothes treating device of the present invention.

[0346] The moving hanger 1000 of the clothing disposal device of the present invention is disposed on the upper part of the inner case 200 and includes a power transmission unit 1400 for swinging the hanger 1900.

[0347] A hanging portion 1700 on which the hanger 1900 is seated or hung is provided at the lower portion of the power transmission portion 1400.

[0348] As a result, when the power transmission part 1400 moves, the hanging part 1700 moves, and the hanger 1900 hung on the hanging part 1700 is swung, thereby producing the effect of hitting the clothes.

[0349] A plurality of power transmission units 1400 are provided, and a plurality of hanging units 1700 are also provided to be connected to the power transmission units 1400. As a result, a large number of clothes corresponding to the number of power transmission units 1400 can be hung inside the inner case 200 and refreshed.

[0350] The moving hanger 1000 further includes a drive unit 1200 that provides power for moving the power transmission unit 1400 .

[0351] The driving unit 1200 may be exposed to the inside of the inner case 200 as long as it can transmit power to the power transmission unit 1400. However, since the driving unit 1200 is operated by receiving electrical energy, it is preferable that it is shielded from exposure to steam or hot air.

[0352] Therefore, the driving unit 1200 is disposed between the upper surface of the inner case 200 and the cabinet 100 and is prevented from being exposed to the receiving space 220 .

[0353] The power transmission part 1400 passes through the inner case 200 to transmit power to the driving part 1200 and then to the hanging part 1700 .

[0354] The power transmission part 1400 extends through the upper surface of the inner case 200 into the receiving space 220. The lower end of the power transmission part 1400 is exposed to the receiving space 220, and the upper end of the power transmission part 1400 is exposed above the inner case 200.

[0355] The power transmission part 1400 may be in the form of a rod, a tube, or a plate, the length of which is greater than the thickness.

[0356] Meanwhile, the upper surface of the inner case 200 supports the loads of the power transmission unit 1400 and the driving unit 1200. The power transmission unit 1400 moves when clothes are hung on it, and the load of the driving unit 1200 is also relatively heavy. Therefore, in order to stably install the moving hanger 1000 on the upper surface of the inner case 200, 1 further comprises a support portion 1800.

[0357] The support part 1800 is disposed on the upper part of the inner case 200 and is coupled to and supported by the cabinet 100. The support part 1800 is made of a metal material that is durable and difficult to deform.

[0358] The power transmission unit 1400 and the driving unit 1200 are seated on the support unit 1800 and disposed on the upper part of the inner case 200. The power transmission unit 1400 passes through the support unit 1800 and extends into the receiving space 220.

[0359] Meanwhile, the driving unit 1200 includes a motor that rotates a rotation shaft, and the driving unit 1200 is configured to drive the power transmission unit 1400 with the power that rotates the rotation shaft.

[0360] However, it is difficult to cause the power transmission unit 1400 to undergo a sufficient displacement simply by rotating the rotation shaft in place.

[0361] Therefore, the moving hanger 1000 further includes a displacement generating unit 1300 coupled to a rotation shaft rotated by the motor, which generates a sufficient displacement (amount of change in position) to move the power transmission unit 1400.

[0362] The displacement generating unit 1300 is connected or coupled to the driving unit 1200 .

[0363] For example, the displacement generating unit 1300 is configured to transmit the power of the driving unit 1200 to the power transmitting unit 1400 .

[0364] The displacement generating unit 1300 includes an eccentric shaft that rotates along a path larger than the diameter of the rotation shaft. The eccentric shaft may be directly connected to the rotation shaft of the driving unit 1200, or may be eccentrically connected to or extend from a power shaft 1240 that rotates with the rotation shaft.

[0365] The displacement generating unit 1300 may have any configuration as long as it can generate a displacement that can move the power transmission unit 1400 back and forth within a predetermined range. The detailed structure will be described later.

[0366] When the driving unit 1200 is operated, the power generated by the rotation shaft generates a displacement of the displacement generating unit 1300 , and the power transmission unit 1400 moves along with the displacement of the displacement generating unit 1300 .

[0367] The displacement generating unit 1300 can directly move the power transmission unit 1400, but can also move the power transmission unit 1400 through an additional configuration.

[0368] The moving hanger 1000 of the present invention is provided to reciprocate the power transmission unit 1400.

[0369] In addition, the moving hanger 1000 of the present invention is configured to rotate the power transmission unit 1400. Specifically, the moving hanger 1000 is configured to rotate the power transmission unit 1400 back and forth within a predetermined angle range, rather than moving the power transmission unit 1400 back and forth in a straight line.

[0370] The power transmission unit 1400 is provided to rotate clockwise or counterclockwise from a normal position, and the clothes hung on the power transmission unit 1400 also move clockwise or counterclockwise. The power transmission unit 1400 is provided to rotate by the moving hanger 1000. However, there is a possibility that the position may change to the left or right side and not move.

[0371] 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 is limited. Therefore, even if the moving hanger 1000 is operated, the vibration generated inside the inner case 200 is rapidly reduced, and the generation of noise is also minimized.

[0372] For this purpose, the moving hanger 1000 further includes a reciprocating rotation unit 1500 that converts continuous rotational energy generated from the driving unit 1200 or the displacement generating unit 1300 into a reciprocating rotational motion of the power transmitting unit 1400 .

[0373] The reciprocating rotation unit 1500 is provided to connect the displacement generating unit 1300 and the power transmitting unit 1400 to each other. The reciprocating rotation unit 1500 is provided to connect the displacement generating unit 1300 and the power transmitting unit 1400 to each other above the inner case 200. The reciprocating rotation unit 1500 prevents the garment from being exposed to the receiving space 220, thereby preventing the garment from being damaged by the reciprocating rotation unit 1500.

[0374] Meanwhile, the moving hanger 1000 is provided so that only one of the plurality of power transmission parts 1400 rotates back and forth.

[0375] However, if only one power transmission unit 1400 rotates, the clothes hung on the rotating power transmission unit may collide with and be damaged by the clothes hung on the other power transmission units 1400. Furthermore, the impact may be transmitted to the moving hanger 1000, which may be damaged.

[0376] Therefore, it is preferable that the moving hanger 1000 is provided to rotate all of the plurality of power transmission parts 1400.

[0377] The moving hanger 1000 rotates the plurality of power transmission units 1400 as a unit. The moving hanger 1400 is provided to simultaneously rotate the plurality of power transmission units 1400 at the same angle. As a result, the clothing disposal device of the present invention can prevent the power transmission units 1400 from colliding with each other.

[0378] It is advantageous for the power generated by the driving unit 1200 to be directly transmitted to the plurality of power transmission units 1400 in order to rotate all of the power transmission units 1400 .

[0379] However, if the driving unit 1200 is configured to directly transmit power to each of the power transmission units 1400, the structure for connecting the driving unit 1200 to all of the power transmission units 1400 becomes complicated.

[0380] In addition, if a plurality of driving units 1200 are provided, or if a plurality of components for connecting all of the power transmission units 1400 are provided in the driving unit 1200, an excessive load may be applied to the inner case 200 or the support unit 1800. In addition, it may be inconvenient to have to control a plurality of driving units 1200.

[0381] Furthermore, 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 each of all power transmitting units 1400, the arrangement and structure of the displacement generating unit 1300 and the reciprocating rotating unit 1500 become complicated, and reliability decreases.

[0382] Therefore, the moving hanger 1000 is configured such that one driving unit 1200 generates power to rotate a plurality of power transmission units 1400 .

[0383] In addition, the moving hanger 1000 is configured so that the power generated from the driving unit 1200 is transmitted preferentially to some of the power transmission units 1400 or some of the reciprocating rotation units 1500, and the remaining power transmission units 1400 or remaining reciprocating rotation units 1500 transmit the power secondarily.

[0384] For example, the reciprocating rotation unit 1500 is configured to receive power transmitted from the driving unit 1200 or the displacement generating unit 1300 and transmit it to a part of the power transmission unit 1400. That is, the moving hanger 1000 is configured to transmit the power generated from the driving unit 1200 intensively to one reciprocating rotation unit 1500, which simplifies the design of the power transmission structure and minimizes power loss.

[0385] The moving hanger 1000 of the present invention is configured to transmit the power transmitted from the driving unit 1200 to one reciprocating rotating unit 1500 and rotate a specific power transmitting unit 1400 connected to the reciprocating rotating unit 1500.

[0386] In addition, the moving hanger 1000 further includes a connecting part 1600 that is provided to transmit the power transmitted to a specific power transmission part 1400 to another power transmission part 1400 .

[0387] For example, the connecting unit 1600 is provided to connect the plurality of power transmission units 1400 to each other, so that when any one of the power transmission units 1400 rotates, the connecting unit 1600 can rotate all of the plurality of power transmission units 1400.

[0388] FIG. 17 shows how the moving hanger of the present invention operates.

[0389] 17(a), when the driving unit 1200 is operated, the power transmission unit 1400 rotates rightward by the reciprocating rotation unit 1500. At this time, the power transmission unit 1400 connected to the connecting unit 1600 also rotates rightward.

[0390] 17(b), when the driving unit 1200 is further operated, the power transmission unit 1400 is rotated leftward by the reciprocating rotation unit 1500. At this time, the power transmission unit 1400 connected to the connecting unit 1600 also rotates leftward.

[0391] This process is repeated, causing the power transmission unit 1400 to rotate left and right.

[0392] At this time, the power transmission unit 1400 is configured to rotate left and right while being fixed in a normal position. The power transmission unit 1400 is fixed to the support unit 1800 so that its position does not change forward, backward, left and right when it rotates.

[0393] The power transmission unit 1400 is fixed so that its position does not move in the vertical, front-rear and width directions.

[0394] However, the power transmission unit 1400 is configured to rotate left and right around a rotation axis in the vertical direction or height direction in which the power transmission unit extends. As a result, when the driving unit 1200 is driven, the hanging unit 1700 rotates back and forth left and right around the power transmission unit 1400 as an axis, and does not move in position.

[0395] Referring to FIG. 17(c), the hanger 1900 is hung on the hanging portion 1700. and a seating portion 1900 coupled to the hook portion 1910. The seating portion 1950 has a surface portion 950 on its surface that prevents the clothes from slipping.

[0396] The seating portions 1950 are provided symmetrically with respect to the hook portion 1910. The hanger 1900 is hung on the hanging portion 1700 so that the seating portions 1950 are arranged in the front-rear direction.

[0397] When the power transmission unit 1400 rotates to the left, the left side of the seat 1950 of the hanger 1900 rotates to the left and the right side of the seat 1950 rotates to the right based on the hook unit 1910. In this case, the angle (I) by which the left side of the seat 1950 rotates is the same as the angle (theta) by which the right side of the seat 1950 rotates, and the distance by which the left side of the seat 1950 moves is the same as the distance by which the right side of the seat 1950 moves.

[0398] As a result, the weight and force moving leftward and the weight and force moving rightward relative to the hanger 1900 are equal and cancel each other out.

[0399] Similarly, even if the power transmission unit 1400 rotates to the right, the weight and force moving leftward and rightward relative to the hanger 1900 are equal and cancel each other out.

[0400] As a result, even when the power transmission unit 1400 rotates, the forces applied to the hanger 1900 are offset with each other, and as a result, the vibration force, excitation force, and inertial force generated from the hanger 1900 itself are minimized. As a result, the inertial force generated from the plurality of power transmission units 1400 is minimized, and the vibration and noise generated from the entire moving hanger 1000 are minimized, and the vibration and noise generated from the entire clothing treatment device 1 are rapidly reduced.

[0401] As a result, even if the drive unit 1200 rotates at maximum output, the moving hanger 1000 or the entire clothing processing device 1 does not generate large vibrations.

[0402] Instead, each surface of the clothes hung on the hanger 1900 is hit by rotating left and right, so that a large hitting force can be ensured.

[0403] As described above, the power transmission unit 1400 is installed to penetrate the inner case 200, and is installed to transmit the power and rotate back and forth in a clockwise or counterclockwise direction. As a result, the power transmission unit 1400 rotates back and forth left and right while being fixed in position at the top of the inner case 200. The power transmission unit 1400 is fixed so that its position cannot be changed up, down, left, or right. In addition to the top, the bottom of the power transmission unit 1400 is also fixed so that its position cannot be changed up, down, left, or right.

[0404] That is, the power transmission unit 1400 is configured to rotate back and forth at a predetermined angle less than one revolution while the center of rotation is fixed.

[0405] As a result, no matter how fast the power transmission unit 1400 rotates, the hanger 1900 remains fixed in position, and one end rotates or moves to one side and the other end to the other side, so that the forces and vibrations transmitted to the power transmission unit 1400 cancel each other out.

[0406] Therefore, vibrations and noises generated by the power transmission part 1400, the hanging part 1700 and the hanger 1900 inside the inner case 200 are minimized.

[0407] As a result, the clothing treatment device of the present invention rotates the driving unit 1200 at a higher rpm. , the power transmission unit 1400 is reciprocated at a faster frequency, thereby enabling the clothes treating device of the present invention to shake the clothes more vigorously.

[0408] In addition, the moving hanger 1000 of the present invention is provided with a power transmission unit 1400 that rotates clockwise or counterclockwise on the spot. Therefore, as described above, no matter how fast the hanger 900 rotates, the vibration or inertial force generated from the hanger 1900 and the clothes is canceled out when it is transmitted to the power transmission unit 1400.

[0409] As a result, even if the driving unit 1200 of the moving hanger 1000 of the present invention is increased above a predetermined RPM, the moving hanger 1000 is not damaged, and vibrations and noises exceeding the limit value can be prevented from occurring in the clothing processing device.

[0410] Therefore, the clothing treatment device of the present invention can drive the drive unit 1200 faster than clothing treatment devices using conventional moving hangers, and can drive the power transmission unit 1400 at a faster frequency, allowing the clothing to be shaken more strongly.

[0411] As a result, the clothing treatment device of the present invention can more reliably remove foreign matter attached to the clothing and more effectively remove wrinkles from the clothing by the moving hanger 1000. Also, the clothing treatment device of the present invention vibrates the clothing more quickly, exposing it to the supplied steam more.

[0412] In addition, the clothes treating device of the present invention can freely adjust the RPM of the driving unit 1200 and adjust the driving frequency or driving cycle of the power transmission unit 1400 according to the course.

[0413] FIG. 18 shows one embodiment of a moving hanger 1000 of the present invention.

[0414] The moving hanger 1000 of the present invention is configured to transmit the power of the driving unit 1200 to only one of the multiple power transmission units 1400, and to transmit the power transmitted to a specific power transmission unit 1400 to other power transmission units 1400 via the connecting unit 1600.

[0415] The displacement generating unit 1300 or the reciprocating rotating unit 1500 is configured to transmit power generated by one driving unit 1200 in a concentrated manner to one power transmitting unit 1400. The connecting unit 1600 transmits the power transmitted to a specific power transmitting unit 1400 to all power transmitting units 1400.

[0416] The connecting part 1600 is provided as a rigid body so that its length is not variable, and is provided to connect all the power transmission parts 1400 together.

[0417] As a result, all of the power transmission parts 1400 rotate simultaneously in the same direction and at the same angle when the connecting part 1600 moves. As a result, the moving hanger 1000 of the present invention rotates a plurality of power transmission parts 1400 back and forth simultaneously or at the same angle at once by one driving part 1200.

[0418] The moving hanger 1000 includes a driving unit 1200 fixed to the upper part of the inner case 200 and providing power for the power transmission unit to move, a plurality of reciprocating rotating units 1500 respectively coupled to the plurality of power transmission units 1400, receiving the power from the driving unit 1200 and rotating so that the rotation direction changes repeatedly, and a connecting unit 1600 provided to connect the plurality of reciprocating rotating units to each other.

[0419] The connecting part 1600 includes a link bar that connects the plurality of reciprocating rotating parts 1500 and rotates the plurality of reciprocating rotating parts 1500 as a unit.

[0420] The connecting portion 1600 is provided in a single piece.

[0421] The connecting unit 1600 is provided to connect all of the power transmission units 1400 together.

[0422] However, when the connecting part 1600 is provided to connect the reciprocating transmission part 1500, the connecting part 1600 may be provided above the support part 1800, so that it can be prevented from being exposed inside the inner case 200.

[0423] The connecting unit 1600 is coupled to either the front or rear of the reciprocating rotation unit 1500, and at least one of the displacement generating unit 1300 and the driving unit 1200 is disposed at the other of the front or rear of the reciprocating rotation unit 1500. Therefore, the connecting unit 1600 can be prevented from interfering with the driving unit 1200.

[0424] The connecting part 1600 is configured to reciprocate in the width direction of the inner case 200 to rotate the plurality of reciprocating rotating parts 1500 .

[0425] The driving unit 1200 includes a motor 1210 that rotates a rotating shaft 1210, a power shaft 1240 that rotates together with the rotating shaft 1210, and a transmission unit 1230 that connects the power shaft 1240 and the rotating shaft 1210 and transmits the rotational force of the rotating shaft 1210 to the power shaft 1240.

[0426] The motor 1210 is fixed to an upper portion of the inner case 200 and configured to rotate the rotating shaft 1220. However, the rotating shaft 1220 is configured to rotate at a speed that is faster than an appropriate period for reciprocating the power transmission unit 1400 in the motor 1210. In consideration of this, if the RPM of the rotating shaft is reduced, the output of the motor 1210 may not be transmitted to the power transmission unit 1400.

[0427] To solve this problem, the transmission unit 1230 transmits the output of the rotary shaft 1220 to the power transmission unit 1400 as is, but is configured to transmit the output at a lower RPM of the rotary shaft 1220.

[0428] The transmission part 1230 is connected to the rotary shaft 1220 to rotate, and has a diameter larger than that of the rotary shaft 1220. Thus, the transmission part 1230 rotates slower than the RPM of the rotary shaft 1220 to transmit the torque of the rotary shaft 1220.

[0429] The power shaft 1240 is provided to be rotated by the transmission unit 1230 , and is provided separately from the rotation shaft 1230 , and is configured to directly transmit power to the power transmission unit 1400 .

[0430] The reciprocating rotation unit 1500 is coupled to the power transmission unit 1400 and is provided to be rotatable together with the power transmission unit 1400 .

[0431] The reciprocating rotation part 1500 is coupled to the upper part of the power transmission part 1400 and includes a reciprocating lever 1510 for rotating the power transmission part 1400 .

[0432] The reciprocating lever 1510 is a rib or rod-shaped member whose rotation center is connected to the support shaft 1410. It can be prepared.

[0433] The reciprocating levers 1510 are coupled to the upper ends of the plurality of power transmission units 1400, respectively, and some of the reciprocating levers 1510 are connected to the transmission unit 1230 so that the power of the motor 1210 is transmitted thereto.

[0434] The reciprocating lever 1510 is configured to rotate reciprocally at a predetermined angle when the transmission unit 1230 is rotated by the motor 1210. The power transmission unit 1400 is coupled to the rotation center of the reciprocating lever 1510 and configured to rotate together with the reciprocating lever 1510.

[0435] A plurality of reciprocating levers 1510 are arranged connected to a connecting portion 1600 .

[0436] The connecting portion 1600 is provided to connect one end of a plurality of reciprocating levers 1510 .

[0437] Therefore, when any one of the plurality of reciprocating levers 1510 rotates, the connecting portion 1600 moves, and the plurality of reciprocating levers 1510 rotate simultaneously.

[0438] The power transmission unit 1400 and the reciprocating lever 1510 are supported by the support unit 1800. The motor 1210 and the transmission unit 1230 are also supported by the support unit 1800.

[0439] FIG. 19 shows the moving hanger 1000 of the present invention separated from the inner case 200.

[0440] The power transmission part 1400 extends from the top to the bottom of the inner case, and the hook part 1700 is coupled to the bottom of the power transmission part 1400 .

[0441] The reciprocating rotation unit 1500 is coupled to each of the power transmission units 1400 and to the upper part of the power transmission unit 1400 , and is easily connected to the driving unit 1200 .

[0442] The power transmission unit 1400 and the reciprocating rotation unit 1500 are provided in plural numbers and are spaced apart from each other by a predetermined distance along the width direction of the inner case.

[0443] The connecting unit 1600 is provided to connect the plurality of power transmission units 1400 or the plurality of reciprocating rotation units 1500 to each other, so that the connecting unit 1600 is provided to rotate the plurality of power transmission units 1400 or the plurality of reciprocating rotation units 1500 as a whole simultaneously.

[0444] The power transmission part 1400 includes a support shaft 1410 that penetrates the upper part of the inner case 200 and is coupled to the reciprocating lever 1510 .

[0445] The support shaft 1410 passes through the support part 1800 and is exposed to the top of the support part 1800 or the top of the inner case 200 .

[0446] The power transmission part 1400 includes an auxiliary support part 1420 connected to the support shaft 1410 and exposed to the receiving space. The auxiliary support part 1420 has a rod shape, and a hook part 1700 is connected and fixed to a lower part of the auxiliary support part 1420.

[0447] The auxiliary support part 1420 is fixed to the support shaft 1410 and is configured to rotate together with the support shaft 1410. Therefore, when the support shaft 1410 rotates due to the reciprocating lever 1510, the auxiliary support part 1420 connected to the support shaft 1410 also rotates, and the hook part 1700 also rotates left and right.

[0448] The reciprocating lever 1510 includes a main lever 1511 that receives power directly from the driving unit 1200 to rotate reciprocally, and an auxiliary lever 1512 that receives power from the main lever 1511 via a connecting unit 1600 .

[0449] The main lever 1511 is provided in a single piece, and is provided so that power is directly transmitted from the driving unit 1200 .

[0450] In the driving unit 1200 , the motor 1210 includes a vertical motor 1211 coupled to the support unit 1800 and a vertical rotation shaft 1221 rotated by the vertical motor 1211 .

[0451] The transmission unit 1230 includes a power pulley 1231 coupled to the vertical rotation shaft 1221 and rotating together with the vertical rotation shaft 1221, a transmission pulley 1232 coupled to the power shaft 1240 and rotating the power shaft 1240, and a belt 1233 connecting a portion of the outer circumferential surface of the power pulley 1231 and the transmission pulley 1232.

[0452] The transmission unit 1230 further includes a pulley support unit 1224 that rotatably supports the power shaft 1240 and the transmission pulley 1232. The pulley support unit 1224 supports the transmission pulley 1232 so that it is arranged next to the power pulley 1231, and is seated on the support unit 1800.

[0453] The power shaft 1240 is provided to transmit the power transmitted from the rotation shaft 1220 to one end of the main lever 1511 .

[0454] The displacement generating unit 1300 is coupled to the power shaft 1240 and receives power. The displacement generating unit 1300 is also connected to the main lever 1511 and rotates the main lever 1511 reciprocally around the support shaft 410.

[0455] For example, the displacement generating unit 1300 includes an eccentric shaft that is eccentrically coupled to the power shaft 1240 and rotates at a predetermined radius around the rotation center of the power shaft 1240 .

[0456] The displacement generating unit 1300 is connected to the end of the main lever 1511. The displacement generating unit 1300 is rotated by the power shaft 1240 to rotate the end of the main lever 1511 back and forth around the support shaft 410.

[0457] The connecting part 1600 includes a link bar 1610 that connects one end of the main lever 1511 that is not connected to the power shaft 1240 or the displacement generating part 1300 to one end of the auxiliary lever 1512 .

[0458] The auxiliary lever 1512 is rotatably connected to another support shaft 1410 that is not connected to the main lever 1511, extends in one direction from the point where it is connected to the support shaft 1410, and is configured to be connected to the link bar 1610.

[0459] The link bar 1610 is provided in the form of a straight frame connecting one end of the main lever 1511 and one end of the auxiliary lever 1512. The ends of the auxiliary levers 1512 are arranged side by side with respect to the link bar 1610 or the width direction.

[0460] The link bar 1610 is provided singly and is provided to rotate the main lever 1511 and the auxiliary lever 1512 simultaneously and at the same time around the respective support shafts 1410 .

[0461] The inner case 200 has a through-hole 230 through which a portion of the support part 1800 is seated to expose the power transmission part 1400 to the receiving space 220 .

[0462] The through-hole 230 is formed in the upper surface 22 of the inner case, and the through-hole 230 is formed in a direction in which the power transmission part 1400 is arranged.

[0463] For example, the power transmission parts 1400 are spaced apart from each other along the width direction of the inner case, and the through holes 230 are arranged along the width direction of the inner case.

[0464] The clothing processing device 1 of the present invention further includes a support frame 120 that is disposed outside the inner case and supports the cabinet 100.

[0465] The support frame 120 is disposed at a position corresponding to a corner of the cabinet 100 or a corner of the inner case 200, and is made of a metal material that maintains the appearance of the clothing treatment device. Both ends of the support part 1800 are seated and supported by the support frame 120, thereby preventing unnecessary impact or load from being transmitted to the upper surface 220 of the inner case.

[0466] FIG. 20 shows the operating method of the moving hanger 1000 of the present invention.

[0467] Referring to FIG. 20( a ), the main lever 1511 is coupled to the support shaft 1410 and includes a main body 15111 coupled to the connecting bar 1610 .

[0468] The main body 15111 is coupled to the support shaft 1410 and includes a main central hole 15115 for rotating the support shaft 1410, and extends from the main central hole 15115 to both sides.

[0469] The main body 15111 has a main receiving hole 15112 at one end to which power is transmitted from the driving unit 1200, and a main transmitting hole 15113 at the other end to which the connecting bar 1610 is seated and coupled.

[0470] The main body 15111 extends from the central hole to the main receiving hole 15112 and further includes a stepped portion 15114 forming a step. The stepped portion 15114 allows one end of the main body 15111 or the main transmitting hole 15113 to be positioned lower than the main central hole 15115.

[0471] This ensures that the power shaft 1240 or the eccentric shaft 1310 disposed above the main central hole 15115 extends a sufficient length from the transmission unit 1230 .

[0472] Meanwhile, the auxiliary lever 1512 includes an auxiliary center hole 15125 connected to the support shaft 1410 and an auxiliary body 15121 having an auxiliary transmission hole 15123 extending from the auxiliary center hole 15125 to one side and connected to the link bar 1610.

[0473] The auxiliary body 15121 is shorter in length than the main body 15111 .

[0474] The distance from the main central hole 15115 to the main transmission hole 15113 is set to be the same as the distance from the auxiliary central hole 15125 to the auxiliary transmission hole 15123 .

[0475] The link bar 1610 is seated on the upper part of the auxiliary transmission hole 15123 and the main transmission hole 15113 to connect the auxiliary lever 1512 and the main lever 1511 to each other.

[0476] 20(b), the driving unit 1200 is configured so that the power shaft 1240 is inserted into the main receiving hole 15112. This directly rotates the power shaft 1240, thereby rotating the main receiving hole 15112 left and right.

[0477] In other words, rotation of the powered shaft 1240 alone may not generate enough displacement to rotate the main receiver aperture 15112 left or right about the main center aperture 15115 .

[0478] For this purpose, the displacement generating unit 1300 is coupled to the power shaft 1240 and configured to generate a displacement greater than the rotation radius of the power shaft 1240 .

[0479] The displacement generating unit 1300 is 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 rotation unit 1500, and the power transmitting unit 1400 rotates reciprocally.

[0480] As described above, the displacement generating unit 1300 includes the eccentric shaft 1310 that extends from the power shaft 1240 and rotates along a trajectory along a predetermined radius.

[0481] The eccentric shaft 1310 has a diameter smaller than that of the power shaft 1240 , is spaced a predetermined distance from the rotation center of the power shaft 1240 , and is coupled to or extends from the power shaft 1240 .

[0482] Therefore, when the power shaft 1240 rotates, the eccentric shaft 1310 rotates in a circle whose radius is the distance from the power shaft 1240 .

[0483] The diameter of the eccentric shaft 1310 is set to be smaller than the diameter or width of the main receiving hole 15112 .

[0484] The eccentric shaft 1310 is inserted into and supported by the main receiving hole 15112 .

[0485] However, the predetermined radius around which the eccentric shaft 1310 rotates is set to be larger than the width or diameter of the main receiving hole 15112. As a result, when the eccentric shaft 1310 rotates, the main receiving hole 15112 is pushed by the eccentric shaft 1310 and moves left and right based on the main central hole 15115.

[0486] As a result, when the eccentric shaft 1310 rotates in a predetermined direction (x), the main receiving hole 15112 of the main body 1511 also rotates back and forth along the predetermined direction (y), and as a result, the central hole 15115 of the main body also rotates in the same direction as the main receiving hole 15112, and the main transmission hole 15113 rotates back and forth in the direction opposite to the predetermined direction (z).

[0487] When the eccentric shaft 1310 rotates, the support shaft 141 rotates together with the main center hole 15115. When the main transmission hole 15113 rotates back and forth, the power transmission unit 1400 rotates back and forth, and the main transmission hole 15113 also rotates back and forth to move the link bar 1610 back and forth, causing the auxiliary lever 1521 to rotate back and forth around the auxiliary center hole 15125 and the support shaft 1410. The power transmission unit 1400 connected to the auxiliary lever 1521 also rotates back and forth.

[0488] The power transmission part 1400 has a spiral along the periphery of the upper part of the support shaft 1410 .

[0489] The main transmission hole 15113 and the auxiliary central hole 15125 are directly coupled and fixed to the support shaft 1410 using a screw or the like.

[0490] However, the power transmission part 1400 further includes a transmission coupling part 1415 that is coupled to the spiral of the support shaft 1410 so as to fix the support shaft 1410 to the main transmission hole 15113 and the auxiliary central hole 15125 after the support shaft 1410 passes directly through the main transmission hole 15113 and the auxiliary central hole 15125.

[0491] Therefore, the support shaft 1410 and the reciprocating lever 1510 are coupled by the transmission coupling part 1415, and the support shaft 1410 and the reciprocating lever 1510 rotate simultaneously.

[0492] Hereinafter, an embodiment in which the control unit 700 of the clothing processing device of the present invention executes any course based on the above-described configuration will be described.

[0493] FIG. 21 shows the process of the laundry treatment device of the present invention performing a course of treating laundry.

[0494] The clothing processing device of the present invention has a maximum allowable power amount set as the maximum amount of power that can be used. The control unit 700 of the clothing processing device of the present invention is set to cut off the power supply when it detects that power consumption will exceed the allowable amount.

[0495] The allowable power amount is smaller than the power amount consumed when simultaneously driving the first heater 841, the second heater 842, and the compressor 342. As a result, the clothing treatment device of the present invention is configured so that the entire steam heater 840 and the compressor 342 cannot be driven simultaneously.

[0496] As a result, the clothing treatment device of the present invention is configured so that the first heater 841 and the second heater 842 cannot be driven simultaneously while the compressor 342 is in operation, and the compressor 342 cannot be driven when the first heater 841 and the second heater 842 are driven simultaneously.

[0497] Therefore, the clothing treatment device of the present invention is set so that when hot air is supplied to the inside of the inner case, the maximum possible steam cannot be supplied at the same time.

[0498] However, the allowable power amount is greater than the power consumed when the first heater 841 and the second heater 842 are simultaneously driven. Also, the allowable power amount is greater than the power consumed when the first heater 841 and the compressor 342 are simultaneously driven. Also, the allowable power amount is greater than the power consumed when the second heater 842 and the compressor 342 are simultaneously driven.

[0499] As a result, the first heater 841 and the second heater 842 can be driven simultaneously, the first heater 841 and the compressor 342 can be driven simultaneously, and the second heater and the compressor 342 can be driven simultaneously.

[0500] Therefore, when the compressor 342 is not driven, the clothing treatment device of the present invention drives the first heater 841 and the second heater 842 simultaneously, and can supply the maximum amount of steam that can be supplied to the inside of the inner case.

[0501] In addition, in the clothing treatment device of the present invention, either one of the first heater 841 and the second heater 842 and the compressor 342 are driven simultaneously, and the steam can be supplied to the inside of the inner case 200 while hot air is being supplied to the inside of the inner case 200 at the same time, and steam can be supplied to the inside of the inner case 200 while hot air is being supplied.

[0502] The clothing treatment device of the present invention initially drives the first heater 841 and the second heater 842 simultaneously to quickly heat the water inside the steam generator 810 and generate steam first. After that, when steam is generated, the clothing treatment device of the present invention drives only one of the first heater 841 and the second heater 842 to maintain the temperature of the water at, for example, the boiling point and continue to generate steam.

[0503] However, in this case, after the steam is generated, the amount of steam injected is reduced compared to when the first heater 841 and the second heater 842 are driven simultaneously.

[0504] The clothing treatment device of the present invention adjusts the amount of steam supplied by driving only one of the first heater 841 and the second heater 842. Therefore, even for materials that are sensitive to moisture and temperature, such as silk or cashmere, only a small amount of steam is supplied, allowing for a sufficient refreshing process.

[0505] When supplying steam to the inside of the inner case, the clothing treatment device of the present invention can use only one of the first heater 841 and the second heater 842, thereby reducing the amount of electricity required to supply steam.

[0506] In addition, the clothing treatment device of the present invention can quickly increase the temperature inside the inner case by driving the compressor 342 when supplying steam, which allows the clothing treatment device of the present invention to quickly complete the drying process to remove moisture from wet clothing, and the refreshing process to sterilize, deodorize, and remove wrinkles from clothing.

[0507] FIG. 21(a) shows an embodiment of a method for controlling a clothing processing device according to the present invention.

[0508] When the refreshing course or standard course that performs the refreshing process is performed, the clothing treatment device of the present invention performs a steam preparation step (A1) in which a steam heater is driven to heat water, and when water is heated and steam is generated during the steam preparation step (A1), a steam injection step (A2) in which the steam is supplied to clothing.

[0509] Generally, the purpose of the refreshing step is to supply moisture to dry clothes, so a large amount of steam needs to be sprayed onto the clothes.

[0510] Therefore, the clothing treatment device of the present invention can simultaneously drive the first heater 841 and the second heater 842 in both the steam preparation step (A1) and the steam injection step (A2).

[0511] In the steam preparation step (A1) and the steam injection step (A2), the compressor 342 may not be driven in consideration of the allowable amount of power.

[0512] The laundry treatment device of the present invention performs a waiting step (A3) to provide time for the laundry to absorb moisture with the supplied steam.

[0513] If the standby step (A3) is performed for a predetermined time, the clothing treatment device of the present invention performs a cooling step (A4) to further lower the surface temperature of the clothing before operating the compressor and operate only the blower fan, thereby preventing heat damage to the clothing.

[0514] When the internal temperature of the inner case 200 decreases and the moisture content of the clothes is sufficient, the clothes treating device of the present invention performs a drying step (A5) by driving at least one of the compressor 342 and the blower fan 351.

[0515] The drying step (A5) dries the moisture contained in the clothes and refreshes the clothes by deodorizing them, removing wrinkles, etc. The drying step (A5) lasts the longest of all the previous steps.

[0516] Meanwhile, since the compressor cannot be driven in the steam injection step (A2), hot air cannot be supplied, and therefore, the temperature inside the inner case 200 and the temperature of the refrigerant flowing through the heat supply unit 400 are relatively low until the drying step (A5) is reached.

[0517] Therefore, in the above-described control method, only when the drying step (A5) is maintained for a relatively long period of time can the refreshing performance of the laundry, including any one of complete drying, sterilization, deodorization, and wrinkle removal, be guaranteed.

[0518] FIG. 21(b) shows another embodiment of the method for controlling a clothes treating device of the present invention.

[0519] However, since the clothing treatment device of the present invention is provided with a plurality of heaters as described above, some of the heaters and compressors can be driven simultaneously.

[0520] For example, since the steam heater 840 includes a first heater 841 and a second heater 842, it is possible to drive either the first heater 841 or the second heater 842 and the compressor at the same time. This allows the refreshing process to be performed in a different manner.

[0521] Therefore, the clothing treatment device of the present invention can quickly raise the temperature inside the inner case 200 before the drying stage by simultaneously driving the heater and compressor before the drying stage, and can more quickly ensure the temperature and time required for complete drying, sterilization, deodorization, and wrinkle removal of clothing.

[0522] As a result, the duration of the drying step can be reduced compared to before. Furthermore, the duration of the drying step is set to be the longest in the refresh step. By reducing the duration of the drying step, the duration of the entire refresh step can be significantly reduced. Furthermore, by reducing the operating time of the compressor, energy efficiency can be significantly improved.

[0523] When any course for refreshing or caring for clothes is performed, the clothes treatment device of the present invention performs a steam preparation step (b1) in which all of the steam heaters 840 are driven to supply steam to the clothes.

[0524] In the steam preparation step (b1), the faster the steam is generated, the shorter the refresh process time can be, so the control unit 700 can drive all the heaters of the steam heater 840.

[0525] In other words, in the steam preparation step (B1), the control unit 700 heats water using the maximum power of the steam heater 840.

[0526] When the steam heater 840 includes the first heater 841 and the second heater 842, the first heater 841 and the second heater 842 can be driven simultaneously to heat water.

[0527] In the steam preparation step (B1), if the detection device 860 detects that steam is generated inside the steam case 810, the clothing treatment device of the present invention performs a preheating step (B2) in which only a portion of the steam heater 840 is driven.

[0528] That is, after steam is generated in the steam case 810, even if only one of the first heater 841 and the second heater 842 is driven, the steam is continuously generated and supplied to the inner case 200.

[0529] In the preheating step (B2), the control unit 700 may drive only one of the first heater 841 and the second heater 842 to supply heat to the inside of the inner case 200.

[0530] As a result, the clothing treatment device of the present invention can increase the internal temperature of the inner case 200 by the steam from the preheating step (B2) and increase the moisture content of the clothing. Also, since only a portion of the steam heater 840 is used in the preheating step (B2), it is possible to secure extra power.

[0531] In the preheating step (B2), the clothing treatment device of the present invention can drive at least one of the compressor 342 and the blower fan 351. As a result, hot air is also supplied into the inner case 200.

[0532] As a result, in at least a portion of the preheating step (B2), the compressor 342, the blower fan 351, and the steam heater 840 can be driven together in an overlapping manner.

[0533] In the preheating step (B2), one of the first heater 841 and the second heater 842 and the compressor 342 are simultaneously driven. Steam and hot air are simultaneously supplied into the inner case 200.

[0534] When either the first heater 841 or the second heater 842 and the compressor 342 are driven simultaneously, the internal temperature of the inner case 200 can be increased from the beginning of the refresh cycle, and hotter air is introduced into the evaporator 341. As a result, the heat exchange performance of the evaporator 341 is strengthened, and the condenser 343 is heated to a higher temperature. Therefore, hotter air is supplied to the inside of the inner case 200, and the inside of the inner case 200 can quickly reach the optimum temperature or minimum temperature required for the refresh cycle. Therefore, the execution time of the subsequent refresh cycle can be significantly reduced.

[0535] Additionally, the overall coefficient of performance (cop) of the heat supply unit 340 is also increased.

[0536] In the preheating step (B2), there are a section in which either one of the first heater 841 and the second heater 842 and the compressor 342 are simultaneously driven, and a section in which only the compressor 342 is driven. Contains one or more of the following:

[0537] 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 also a section in which only the compressor 342 is driven.

[0538] However, it is preferable that the section in which only the compressor 342 is driven is disposed after the section in which the steam heater 840 and the compressor 342 are driven.

[0539] This is because it is more advantageous to drive the heat supply unit 340 if air with high heat capacity is supplied to the evaporator 341 before the compressor 342 is driven. That is, when the steam is supplied to the inner case 200 by the steam heater 840, not only the temperature inside the inner case 200 but also the absolute humidity increases, and the air with high heat capacity comes into contact with the evaporator 341.

[0540] Specifically, the preheating step (B2) includes a first section in which either one of the first heater 841 and the second heater 842 and the compressor 342 are driven, and a second section in which the driving of the first heater 841 and the second heater 842 is stopped and only the compressor 342 is driven.

[0541] The first section supplies hot air and steam to the inner case 200, thereby increasing the temperature inside the inner case 200 and the heat amount of the air flowing into the circulation duct 320.

[0542] The second section allows hot air to be supplied into the inner case 200 in earnest, thereby satisfying the minimum temperature conditions for refreshing the clothes by deodorizing, removing wrinkles, sterilizing, and the like.

[0543] In the preheating section (B2), the first heater 841 is driven. As a result, a larger amount of steam is supplied to the inside of the inner case 200 than when the first heater 841 is driven, and the temperature inside the inner case 200 and the heat amount of the air flowing into the circulation duct 320 can be further increased.

[0544] Alternatively, in the preheating section (B2), the second heater 841 is driven.

[0545] Therefore, the preheating section (B2) gradually increases the temperature inside the inner case 200 and can stably maintain the increased temperature for a longer period of time, thereby ensuring the time required for sterilization and the like.

[0546] It also prevents the clothes from being deformed by moisture at high humidity.

[0547] Meanwhile, the clothing treatment device of the present invention is configured to stop the operation of the steam heater 840 in the preheating section (B2) if the internal temperature of the inner case 200 rises suddenly or the temperature of the refrigerant discharged from the compressor 342 exceeds the limit temperature.

[0548] In addition, the clothing treatment device of the present invention is configured to repeatedly turn on and off either the first heater 841 or the second heater 842 in the preheating section (B2). That is, when the temperature of the refrigerant approaches or exceeds the limit temperature, the control unit 700 can stop the operation of the steam heater 840, and when the temperature of the refrigerant reaches a safe temperature lower than the limit temperature, the control unit 700 can stop the operation of the steam heater 840. In addition, when the internal temperature of the inner case approaches or exceeds the target temperature, the control unit 700 may stop driving the driven steam heater 840, and when the internal temperature reaches a cooling temperature lower than the target temperature, the control unit 700 may stop driving the driven steam heater 840 and repeat the process of driving the steam heater 840 again.

[0549] Meanwhile, even if the steam heater 840 is driven intermittently, the purpose of the preheating section (B2) is to quickly increase the internal temperature of the inner case 200, so the time during which the first heater 841 and the second heater 842 are driven is set to be longer than the time during which the first heater 841 and the second heater 842 are stopped.

[0550] The preheating section (B2) is performed for a predetermined time and is terminated when the temperature inside the inner case or the temperature of the refrigerant is maintained at a predetermined temperature for a predetermined time or more.

[0551] When the preheating section (B2) is completed, the clothing treatment device of the present invention performs a steam injection step (B3) to fully supply steam into the inner case 200. In the steam injection step (B3), the first heater 841 and the second heater 842 are simultaneously driven to supply a large amount of steam to the inner case 200.

[0552] Since the steam injection step (B3) is performed while the clothes hung in the inner case 200 are heated to a predetermined level in the preheating step (B2), the moisture content of the clothes increases significantly.

[0553] The steam injection step (B3) is performed for a shorter period than the steam injection step (A2) without the preheating step (B2) because a predetermined level of steam has already been supplied in the preheating step (B2), and therefore the amount of steam to be further supplied is set to be small.

[0554] The steam injection step (B3) is terminated when a guaranteed time has elapsed for the clothes to be sufficiently moistened.

[0555] When the steam injection step (B3) is completed, a drying step (B6) is performed to dry the clothes with hot air. However, when the steam injection step (B3) is completed, a waiting step (B4) may be performed first to wait a predetermined time to ensure that the steam injected into the inner case 200 has time to penetrate the entire clothes.

[0556] The standby step (B4) is a state in which the steam heater 840 and the compressor 342 are not driven.

[0557] The standby step (B4) prevents the steam injected into the inner case from evaporating immediately before it is absorbed into the clothes, and prevents damage to the clothes caused by a sudden increase in the surface temperature due to further supply of hot air when the surface temperature of the clothes has already increased due to the steam.

[0558] The drying step (B6) is a step of driving the compressor 342 to supply hot air to the inner case 200. Therefore, if hot air is supplied when the temperature inside the inner case 200 is not below a safe temperature, the temperature inside the inner case 200 may rise above the critical temperature, damaging the clothes.

[0559] Therefore, before the drying step (B6), a cooling step (B5) is performed in which the blower fan 352 is driven. In the cooling step (B5), the control unit 700 drives the blower fan 352 but stops the compressor 342 and the steam heater 340. .

[0560] In the cooling step (B5), the air inside the inner case 200 is circulated along the circulation duct 200 and cooled.

[0561] When the internal temperature of the inner case 200 drops below a safe temperature or the cooling step B5 has been performed for a required time, the cooling step B5 is terminated.

[0562] The laundry treatment device of the present invention performs a drying step (B6) of supplying hot air to the laundry until the moisture content of the laundry falls below a predetermined level.

[0563] The control unit 700 recognizes that the moisture content has decreased to a predetermined level or lower by detecting the temperature inside the inner case 200 or the temperature of the refrigerant.

[0564] For example, if the moisture content of the clothes is high, the temperature of the clothes re-entering the circulation duct 320 due to the heat of evaporation will not increase or will not increase rapidly even if the drying step (B6) is performed.

[0565] However, when most of the clothes are dried and the moisture content is below a predetermined level, the heat of vaporization is small, so the temperature of the air entering the circulation duct 320 rises rapidly and eventually corresponds to the temperature of the hot air.

[0566] This is because the temperature of the refrigerant also follows a pattern similar to that of the refrigerant entering the circulation duct 320 .

[0567] When the control unit 700 detects that the moisture content of the clothes is low, the clothes are sufficiently dried, and the minimum time required for refreshing has elapsed, the control unit 700 ends the drying step (B6).

[0568] Alternatively, the control unit 700 may terminate the drying step (B6) when the time during which the clothes are exposed to the minimum drying temperature condition or above reaches or exceeds the minimum time.

[0569] As a result, the clothing treatment device of the present invention can significantly reduce the duration of the drying step (B6) by further placing a preheating step (B2) before the drying step (B6) and increasing the overall time for the internal temperature of the inner case 200 to reach or exceed the minimum temperature condition.

[0570] Meanwhile, the clothing treatment device of the present invention continuously maintains the compressor 342 in a stopped state from the time the compressor 342 is driven in the preheating section (B2) until the drying step (B6) is performed after the compressor 342 is stopped.

[0571] Hereinafter, an embodiment for optimally determining the capacity of the heater when a plurality of steam heaters 840 are provided will be described.

[0572] As described above, the control unit 700 is configured to control the heat supply unit 340 and the steam supply unit 800 to operate within the allowable power amount and to perform any course for treating the clothes.

[0573] The sum of the driving power of the compressor 342, the driving power of the first heater 841 and the driving power of the second heater 842 is set to be larger than the allowable power amount.

[0574] The sum of the driving power of the compressor 342 and the driving power of the first heater 841 is set to be smaller than the allowable power amount, and when the sum of the driving power of the compressor 342 and the driving power of the second heater 841 is set to be smaller than the allowable power amount, the specifications of the compressor 342, the first heater 841, and the second heater 842 may be set in various ways.

[0575] The driving power of the compressor 342 is defined as the amount of power required when the compressor 342 is driven at the maximum rpm, and is determined according to the individual specifications of the compressor 342 .

[0576] The driving power of the first heater 841 is defined as the amount of power required to drive the first heater 841 and is determined according to the individual specifications of the first heater 841 .

[0577] The driving power of the second heater 842 is defined as the amount of power required to drive the second heater 842 and is determined according to the individual specifications of the second heater 842 .

[0578] The driving power of the compressor 342 is determined as an amount of power that can remove all the moisture contained in the clothes within an allowable time when the control unit 700 performs the arbitrary course.

[0579] The driving power of the second heater 842 is set to be smaller than the driving power of the first heater 841. A criterion for determining the driving power of the first heater 841 and a minimum criterion for determining the driving power of the second heater 842 are required.

[0580] The first heater 841 or the second heater 842 can be operated without any problem no matter what driving power it has, as long as the driving power is equal to or less than the allowable power amount minus the driving power of the compressor.

[0581] However, if the driving power of the first heater 841 or the second heater 842 is set too small, the amount of heat and moisture required to perform the desired course cannot be supplied to the inside of the inner case 200.

[0582] Furthermore, if the driving power of the first heater 841 or the second heater 842 is set too high, the amount of heat and moisture required to perform the desired course is excessively supplied to the inner case 200.

[0583] Since the second heater 842 is set to have a smaller driving power than the first heater 841, it is first necessary to determine the optimum driving power for the second heater 842.

[0584] Figures 22 and 23 show an embodiment in which the specifications of the steam heater are determined based on temperature and water consumption. Referring to Figure 22, the time required for the steam heater to reach a predetermined temperature when operated with various specifications is shown.

[0585] During the execution of a desired cycle, the control unit 700 uses the steam heater 840 to increase the moisture content of the clothes and raise the internal temperature of the inner case 200. However, since the inner case 200 is sealed, the moisture content of the clothes will be sufficiently high during the execution of the cycle regardless of the driving power of the steam heater 840. Therefore, the steam heater 840 needs to ensure the minimum driving power required to raise the internal temperature of the inner case 200 above the set temperature.

[0586] The set temperature is defined as the minimum temperature at which wrinkles and creases in the clothes can be removed. The target temperature (T) is defined as a temperature higher than the set temperature, which evaporates the moisture contained in the clothes and eradicates bacteria, mites, etc. on the clothes.

[0587] For example, the set temperature is defined as 37°C or higher, and the target temperature (T) is defined as 60°C or higher.

[0588] The driving power of the second heater 842 is set to a specification that increases the internal temperature of the inner case 200 to at least a target temperature (T) or higher.

[0589] On the other hand, even if the second heater 842 is driven and the internal temperature of the inner case 200 rises to the target temperature (T), if the target temperature is reached slowly, an excessively long time will pass when performing the course, and energy efficiency will decrease.

[0590] Therefore, the driving power of the second heater 842 is set to raise the internal temperature of the inner case 200 to a target temperature or higher before the delay time (t7). The delay time is determined as the average time for which the steam heater 840 operates during the given course.

[0591] For example, the delay time (t7) is set within 40 minutes. When the allowable power of the laundry treatment device of the present invention is set to 1500W to 1600W, the driving power of the second heater 842 is determined in the range of 400W to 900W, taking into consideration the driving power of the first heater 841 and the driving power of the compressor 342. Referring to FIG. 22, when the second heater 842 is driven at the first power (I When the inner case 200 is configured to be driven at a second power (II W) higher than the first power, a third power (III W) higher than the second power, a fourth power (IV W) higher than the third power, a fifth power (V W) higher than the fourth power, or a sixth power (VI W) higher than the fifth power, the temperature inside the inner case 200 increases over time.

[0592] It can be confirmed that regardless of the specifications for driving the second heater 842 at any of the first power (IW) to sixth power (VIW), the internal temperature of the inner case 200 always reaches the target temperature (T).

[0593] However, when the second heater 842 is provided with specifications to be driven at the first power (IW), the inside of the inner case 200 reaches the target temperature beyond the delay time, and it can be confirmed that the inside of the inner case 200 reaches the target temperature (T) within the delay time (t7) from when it is provided with specifications to be driven at the second power (II W) or higher.

[0594] Therefore, it is considered preferable that the second heater 842 is provided with a driving power specification that allows it to be driven at least at the second power (II W).

[0595] FIG. 23 shows the time taken to reach the predetermined temperature and the amount of water used when the second heater 842 is driven in various specifications.

[0596] It can be seen that the time required to reach the target temperature decreases as the driving power of the second heater 842 increases. For example, when the driving power of the second heater 842 is set to the first power (1W), it takes the longest time to reach the target temperature.

[0597] For example, when the drive power of the second heater 842 is determined by the specifications of the first power (IW), an overtime (t5) is required.

[0598] For example, the first power (IW) corresponds to 400W.

[0599] The overtime (t5) is set to 40 minutes or more, for example, 46 minutes.

[0600] The excess time (t5) is a time that is longer than the delay time (t4) and causes a course delay.

[0601] When the driving power of the second heater 842 is set to the second power (II W), it takes a delay time (t4) shorter than the overtime (t5) to reach the target temperature.

[0602] For example, the second power (II W) corresponds to 500 W.

[0603] The delay time (t4) is set to within 40 minutes, for example, 35 minutes.

[0604] Therefore, since the driving power of the second heater 842 is the second power (II W), there is no delay in the course and it is believed to enter the appropriate specification section. When the driving power of the second heater 842 is set to the third power (III W), it takes a stabilization time (t3) that is shorter than the delay time (t4) to reach the target temperature.

[0605] For example, the third power (III W) corresponds to 600 W.

[0606] The stabilization time (t3) is also set to within 40 minutes, for example, 28 minutes.

[0607] When the driving power of the second heater 842 is set to the fourth power (IV W), it takes an economical time (t2) shorter than the safe time (t3) to reach the target temperature.

[0608] For example, the fourth power (IV W) corresponds to 700W.

[0609] Furthermore, the economical time (t2) is set to 40 minutes or less, for example, 25 minutes. When the driving power of the second heater 842 is set to the fifth power (VW), it takes a quick time (t1) shorter than the economical time (t2) to reach the target temperature.

[0610] For example, the fifth power (VW) corresponds to 800W.

[0611] In addition, the rapid time (t1) is set to 40 minutes or less, for example, 23 minutes. When the driving power of the second heater 842 is set to the sixth power (VI), it takes a shortened time (t0) shorter than the rapid time (t1) to reach the target temperature.

[0612] For example, the fifth power (VW) corresponds to 800W.

[0613] The shortened time (t0) is set to 40 minutes or less, for example, 21 minutes.

[0614] It can be seen that the higher the specification of the driving power of the second heater 842, the shorter the time required to reach the target temperature.

[0615] However, the time required to reach the target temperature (T) does not decrease in proportion to the increase in the driving power specification of the second heater 842. For example, the difference between the delay time (T4) and the stabilization time (T3) is smaller than the difference between the overtime (T5) and the delay time (T4).

[0616] Furthermore, the difference between the stabilization time (T3) and the economic time (T2) is smaller than the difference between the delay time (T4) and the stabilization time (T3).

[0617] Furthermore, the difference between the economic time (T2) and the quick time (T1) is smaller than the difference between the stable time (T3) and the economic time (T2).

[0618] As described above, it is expected that the higher the driving power of the second heater 842, the shorter the time to reach the target temperature and the corresponding reduction in water consumption. However, since the time to reach the target temperature is not reduced in proportion to the difference in driving power, the reduction in water consumption does not continue.

[0619] Basically, no matter what driving power the second heater 842 is driven with, the target temperature (T) cannot be reached unless the heater is driven for 20 minutes or more.

[0620] In other words, it appears that the higher the driving power of the second heater 842, the faster the target temperature is reached, and therefore the amount of water used tends to decrease. However, as the driving power of the second heater 842 increases, the amount of steam generated per unit time increases, and the driving time is maintained for a predetermined period of time or longer, so that a larger amount of steam is supplied to the inside of the inner case 200. Therefore, it cannot be concluded that the higher the driving power of the second heater 842, the less water is needed to raise the temperature inside the inner case 200 to the target temperature.

[0621] In summary, the second heater 842 must be set to a specification that uses water up to a tolerance level and raises the temperature inside the inner case 200 to the target temperature. The tolerance level is set to an amount of water that allows at least five cycles when the water supply bucket 30 is filled to the maximum. For example, the tolerance level is set to 440 g or less.

[0622] 23, as the driving power of the second heater 842 is set to be gradually higher, such as first power (1W), second power (IIW), and third power (IIIW), the amount of water consumption decreases from excessive (A3), medium (A2), and small (A1). This can be interpreted as meaning that the higher the driving power of the second heater 842, the more steam is supplied to the inside of the inner case 200, which increases the internal temperature of the inner case 200 more quickly, thereby reducing the overall amount of water consumption.

[0623] The small amount (A1) and the medium amount (A2) are defined as amounts of water consumption that ensure the course is performed more than the target number of times, taking into account the volume of the water bottle. For example, the target number of times is defined as four or more times. However, when the driving power of the second heater 842 is set to a fourth power (IVW), a fifth power (VW), or a sixth power (VIW) that is greater than the third power (IIIW), the water consumption gradually increases to the medium amount (A2), excessive amount (A3), and excessive amount (A4).

[0624] For example, the excessive amount (A3) is set to 460 g, the medium amount (A2) to 430 to 440 g, and the appropriate amount (A1) to 420 g.

[0625] This is interpreted as meaning that as the driving power of the second heater 842 is set higher, more steam is supplied to the inside of the inner case 200 and the target temperature can be reached more quickly, but the amount of steam generated per unit time becomes too large, and the amount of water used actually increases.

[0626] Therefore, the second heater 842 is set to a driving power of not less than the second power (II W) and not more than the fourth power (IV W) in consideration of the time required to reach the target temperature and the amount of water used. It is best to do so.

[0627] That is, the second heater 842 is designed to have an optimum driving power that allows the target temperature to be reached in the shortest possible time and minimizes the amount of water used.

[0628] The optimal driving power of the second heater 842, which can prevent delays in the course of using as little water as possible and also save energy, is considered to be the third power (III V). However, taking into consideration the environment in which the clothing treatment device is placed, the amount of power supplied, and the weight and material of the clothing placed inside the inner case 200, the optimal driving power of the second heater 842 is determined to be within the range of the first to fourth powers.

[0629] The optimum driving power of the first heater 841 is determined in the range of the second to fourth powers, taking into consideration the standard of the second heater 842.

[0630] Alternatively, the driving power of the first heater 841 is determined to be equal to or smaller than the value obtained by subtracting the driving power of the second heater from the allowable power amount.

[0631] For example, the driving power of the first heater 841 is set to a seventh power that is set higher than the sixth power to an eighth power that is set higher than the seventh power.

[0632] For example, the driving power of the first heater 841 is set in the range of 800W to 1100W.

[0633] For example, if the allowable power is 1500 W and the driving power of the second heater 842 is determined to be 600 W, the driving power of the first heater 841 is determined to be 900 W. Also, the driving power of the first heater 841 is determined to be 880 W with an error of about 20 W so as not to exceed the allowable power when the second heater 842 is driven together.

[0634] Meanwhile, the specifications of the steam heater 840 of the laundry treatment device of the present invention are determined according to standards different from the water consumption amount and temperature conditions described above.

[0635] 24 and 25 show an embodiment in which the specifications of the steam heater are determined based on the dehumidification amount of the heat supply section.

[0636] In the clothing treatment device of the present invention, the specifications of the steam heater 840 are determined based on the dehumidifying performance or dehumidification amount of the evaporator 341.

[0637] The main purpose of the clothing treatment device of the present invention is not the drying process to remove moisture contained in the clothing, but rather to perform refreshing processes such as deodorizing, removing wrinkles, and sterilizing the clothing.

[0638] The refreshing process is a process in which moisture is supplied to clothes with a low moisture content to increase the moisture content, and then the moisture is evaporated, foreign matter, odorous substances, dust, etc. attached to the clothes are removed, the fibers constituting the clothes are aligned properly, and wrinkles are removed.

[0639] Therefore, in the clothing treatment device of the present invention, the driving power of the first heater 841 and the second heater 842 is set so as to generate an amount of steam that is greater than the amount of dehumidification of the heat supply unit 340.

[0640] Therefore, the clothing treatment device of the present invention has a steam amount generated from the first heater 841 and The specifications of the first heater 841 and the second heater 842 are determined so that the sum of the amount of steam generated from the first heater 841 and the amount of steam generated from the second heater 842 is greater than the amount of moisture removed by condensation in the evaporator 341 .

[0641] Therefore, when the first heater 841 and the second heater 842 are driven, it is possible to ensure that the humidity inside the inner case 200 and the moisture content of the clothes are always high.

[0642] In the clothing treatment device of the present invention, the first heater 841 can be used to increase both the temperature and the relative humidity inside the inner case 200, and the second heater 842 can be used to increase the temperature inside the inner case 200 in a concentrated manner, while maintaining or even decreasing the relative humidity inside the inner case 200.

[0643] As a result, for a sterilization course where maintaining the temperature inside the inner case 200 is important and where excessive moisture supply is not required, one or more of the second heater 842 and the compressor 342 can be driven, and for a standard course or refresh course where the temperature inside the inner case 200 is increased to increase the moisture content of the clothes, one or more of the first heater 841 and the compressor 342 can be driven.

[0644] Referring to FIG. 24( a ), the first heater 841 is provided so that the amount of steam generated is greater than the amount of dehumidification condensed in the evaporator 341 .

[0645] Specifically, the first heater 841 is provided so that the average amount of steam generated per minute is greater than the average amount of dehumidification per minute of the evaporator.

[0646] Alternatively, the first heater 841 is provided so that the maximum amount of steam that can be generated is greater than the maximum amount of dehumidification of the evaporator that can condense moisture.

[0647] When the first heater 841 and the compressor 342 are driven simultaneously, the first heater 841 generates steam and flows into the inner case 200, and the evaporator 341 condenses moisture from the air flowing into the inner case 200.

[0648] However, since the amount of steam injected from the first heater 841 is greater than the amount of dehumidification from the evaporator 341, a part of the steam or moisture is discharged from the discharge hole 232.

[0649] 24(b), the first heater 841 and the compressor 342 are simultaneously driven to supply hot air and steam into the inner case 200. After that, when the driving of the first heater 841 and the compressor 342 is stopped, moisture (S) remains inside the inner case 200, and the moisture content of the clothes (L) increases.

[0650] As a result, when the compressor 342 and the first heater 841 are simultaneously driven for more than a predetermined time, the humidity inside the inner case increases.

[0651] Naturally, if the compressor 342, the first heater 841, and the second heater 842 are simultaneously driven for more than a predetermined time, the humidity inside the inner case increases.

[0652] For this reason, the driving power of the first heater 841 is determined to be in the range of 800 to 1100 w.

[0653] Referring to FIG. 25(a), the second heater 842 is provided so that the amount of steam generated is equal to or less than the amount of dehumidification of the evaporator.

[0654] Specifically, the second heater 842 is configured so that the average steam generation rate per minute is equal to or less than the average dehumidification rate per minute of the evaporator.

[0655] Alternatively, the second heater 842 is configured so that the maximum steam production rate is equal to or less than the maximum dehumidification rate of the evaporator.

[0656] In addition, the average amount of steam generated by the second heater 842 is set to be smaller than the average amount of dehumidification by the evaporator 341 .

[0657] When the second heater 842 and the compressor 342 are driven simultaneously, the first heater 842 generates steam and flows into the inner case 200, and the evaporator 341 condenses moisture from the air flowing into the inner case 200.

[0658] However, since the amount of steam injected from the second heater 842 is greater than the amount of dehumidification from the evaporator 341, only hot air from which moisture has been removed is discharged from the exhaust hole 232.

[0659] 25(b), the second heater 842 and the compressor 342 are simultaneously driven to supply hot air and steam into the inner case 200. After that, when the second heater 842 and the compressor 342 are stopped, the inside of the inner case 200 is dried and no moisture (S) remains. Also, the moisture content of the clothes (L) is reduced or at least partially dried.

[0660] As a result, when the compressor 342 and the second heater 842 are simultaneously driven for a predetermined time or longer, the humidity inside the inner case 200 is maintained or decreased.

[0661] As described above, the standard of the dehumidification amount that determines the specifications of the second heater 842 is set to the amount of dehumidification that is dehumidified from the evaporator 341 when a specific course is followed.

[0662] For example, the laundry treatment device may be equipped to perform not only the refresh course described above but also the drying course.

[0663] Specifically, the refresh course corresponds to a course in which clothes are de-wrinkled, deodorized, sterilized, and dried in the process of supplying steam to the clothes and then drying them again.

[0664] When the refresh course is performed, the control unit performs a control method as shown in FIG.

[0665] The control unit can stop driving the compressor during the refresh course, during an injection stage in which steam is injected into the inner case in earnest, a standby stage in which neither steam nor hot air is supplied into the inner case, and a cooling stage in which only the blower fan is driven.

[0666] Since the refresh course aims to process clothes that are not wet or clothes with a moisture content of 50% or less, the control unit can set up a section in which the supply of steam or hot air is stopped to prevent the clothes from being thermally damaged.

[0667] However, the drying course is suitable for wet clothes or clothes with a moisture content of 50% or more. Correct.

[0668] Since the main purpose of the drying course is to dry the clothes, once hot air is supplied to the clothes, it must be continued until the clothes are completely dried. If the supply of hot air is stopped, the drying process will be delayed accordingly, and additional energy will be required to supply hot air again.

[0669] Therefore, when the drying course is performed, the control unit drives the compressor 342 to generate hot air and maintains the operation of the compressor 342 until the drying course is completed or the clothes are completely dried.

[0670] Therefore, the drying course is different from the refreshing course in that the waiting and cooling steps are omitted.

[0671] Of course, the laundry treatment device of the present invention includes the steam preparation step (B1) and the preheating step (B2) in the drying course, thereby quickly raising the temperature inside the inner case to a temperature higher than the temperature at which the laundry is dried in the drying course.

[0672] As a result, the drying course is set to perform only the drying step (B6), and to perform the steam preparation step (B1), preheating step (B2), and drying step (B6), but omit the steam injection step (B3), waiting step (B4), and cooling step (B5).

[0673] The specifications of the first heater 841 or the second heater 842 are determined based on the drying course.

[0674] For example, the specifications of the second heater 842 are determined based on the amount of moisture removed from the evaporator 842 during the time the drying course is performed.

[0675] Specifically, the second heater 842 is provided so that the amount of steam generated in the drying course is equal to or less than the amount of dehumidification of the evaporator 341 in the drying course.

[0676] Alternatively, the second heater 842 is provided so that the average amount of steam produced per minute during the drying course is equal to or less than the average amount of moisture removed per minute by the evaporator during the drying course.

[0677] Alternatively, the second heater 842 is provided so that the maximum amount of steam generated in the drying course is equal to or smaller than the maximum amount of dehumidification of the evaporator in the drying course.

[0678] Alternatively, the average amount of steam generated by the second heater 842 in the drying course is set to be smaller than the average amount of dehumidification by the evaporator 341.

[0679] Meanwhile, since the drying course continues until the clothes are completely dried, the running time of the drying course becomes even longer when there is a large amount of clothes. In this case, the amount of dehumidification from the evaporator 342 increases further, making it difficult to determine the specifications of the second heater 842 based on the amount of dehumidification. Therefore, the second heater 842 is determined based on the amount of dehumidification from the evaporator 342 when the drying course is performed for a reference time. Therefore, when the drying course is performed for a reference time, the amount of steam generated by the second heater 842 is set to be equal to or less than the amount of dehumidification from the evaporator 342.

[0680] For example, the reference time is set to within 40 minutes. For example, the reference time is set to 45 minutes. is set to

[0681] The dehumidification amount of the evaporator 342 is set on the assumption that a sufficient amount of moisture to be dehumidified exists inside the inner case 200 for the reference time.

[0682] The amount of steam generated by the second heater 842 during the reference time in the drying course is set to be smaller than the amount of dehumidification by the evaporator 341 during the reference time in the drying course.

[0683] When determining the specifications of the second heater 842 based on the dehumidification amount, the method and standard for measuring the dehumidification amount must be clear.

[0684] The dehumidification amount is defined as the amount of water condensed in the evaporator 341 when the compressor 342 is driven.

[0685] For example, the dehumidification amount is measured by the amount of water condensed in the evaporator 341 when the compressor 342 is driven during the drying course.

[0686] The dehumidification amount is defined based on the amount of weight reduction of the clothes hung up during a predetermined time or during the execution time of any course.

[0687] For example, in the drying course, the dehumidification amount of the evaporator 341 is measured by the amount of weight loss of the clothes during the drying course.

[0688] The weight of the clothes is detected by the control unit 700 based on the change in the driving frequency or driving RPM of the moving hanger 1000, the amount of power, or the like.

[0689] The dehumidification amount is measured by the amount of water lost in the water supply tub 30 during a predetermined time or during the execution time of any course.

[0690] The dehumidification amount is measured by the amount of water that is condensed in the evaporator 341 and collected in the water collection section or drain tank 40 during a predetermined time or an arbitrary course execution time.

[0691] In addition, the specifications of the first heater 841 and the second heater 842 are determined to be within a predetermined range based on the dehumidification amount of the evaporator in any refresh course other than the dry course performed by the control unit 700. The refresh course is generally broadly divided into a basic course and a powerful course.

[0692] The basic course includes the standard course or the boiling course, and the powerful course corresponds to a course that processes clothes more quickly than the basic course.

[0693] The basic course is a course in which the compressor 342 is driven at a basic rpm, such as a standard course, and the powerful course is a course in which the compressor 342 is driven at a powerful rpm higher than the basic rpm.

[0694] The basic course refers to all courses in which the compressor 342 is driven at a basic rpm, and the basic courses are classified in detail according to the time the compressor 342 is driven, which of the first heater 841 and the second heater 842 is driven, the amount of steam supplied to the inside of the inner case 200, the steam injection time, etc.

[0695] The powerful course is defined as a course in which the average rpm of the compressor 342 is set higher than the average rpm of the compressor 342 driven in the basic course.

[0696] The powerful course is defined as a course in which the maximum rpm of the compressor is set higher than the maximum rpm of the compressor 342 driven in the basic course.

[0697] The strong course is defined as a course in which the duration of the compressor 342 is set longer than the duration of the compressor 342 driven in the basic course.

[0698] The powerful course is defined as a course that drives the compressor 342 at a higher output than the output that drives the compressor 342 in the basic course.

[0699] For example, the standard course is a course in which the compressor 342 is driven at the base rpm and either the first heater 841 or the second heater 842 is driven simultaneously, and the boiling course is a course in which the compressor 842 is driven at the base rpm and the second heater 842 is driven simultaneously.

[0700] In the boiling / washing course, the second heater 842 is driven intermittently and repeatedly.

[0701] This is because the boiling course maintains the internal temperature of the inner case 200 at the sterilization temperature for a long period of time, preventing excessive moisture from being supplied to the inside of the inner case 200 and preventing overloading of the compressor 342.

[0702] The powerful course refers to all courses in which the compressor 342 is driven at a powerful rpm, and the powerful course is also classified in detail according to the time the compressor 342 is driven, which of the first heater 841 and the second heater 842 is driven, the amount of steam supplied inside the inner case 200, the steam injection time, etc.

[0703] Of course, the basic course and the powerful course may each be defined as one specific course.

[0704] As a result, the basic course is a course in which normal hot air is supplied inside the inner case, and the powerful course is a course in which hotter air than the basic course is supplied inside the inner case, and which is thought to process clothes more quickly than the basic course.

[0705] Meanwhile, in all the courses corresponding to the basic course, the driving rpm of the compressor 342 is the same, so the amount of dehumidification by the evaporator 341 is similar.

[0706] In addition, all the courses corresponding to the powerful course have the same driving rpm of the compressor 342, and therefore the dehumidification amount of the evaporator 341 is similar. The dehumidification amount of the evaporator 341 in the powerful course is greater than the dehumidification amount of the evaporator 341 in the basic course.

[0707] At least one of the first heater 841 and the second heater 842 is provided with specifications such that the amount of steam generated in the basic course corresponds to 80 to 120% of the dehumidification amount of the evaporator.

[0708] For example, the amount of steam generated by the second heater 842 is determined to be 80 to 120% based on the amount of dehumidification by the evaporator 841 in the basic course.

[0709] For example, the second heater 842 is in the preheating section (B2) during the refresh course. The steam injection amount is determined based on the dehumidification amount of the evaporator 841 in a range of 80 to 120%.

[0710] The preheating section (B2) is a section in which the compressor 342 and the second heater 842 can be driven simultaneously, so that the dehumidification amount and the amount of steam injected by the second heater 842 can be intuitively compared.

[0711] For example, the second heater 842 corresponds to a specification of 450 to 700W, specifically, a specification equivalent to 600W.

[0712] At least one of the first heater 841 and the second heater 842 is provided with specifications such that the amount of steam generated in the strong course corresponds to 110 to 150% of the dehumidification amount of the evaporator.

[0713] For example, the amount of steam generated by the first heater 841 is determined to be 110 to 150% based on the dehumidification amount of the evaporator 841 in the strong course. For example, the first heater 841 is determined to have a specification of 800 to 1000 W, such as 800 W or 950 W.

[0714] FIG. 26 shows an embodiment of the optimum driving method for the steam heater.

[0715] In the clothing treatment device of the present invention, either the first heater 841 or the second heater 842 is driven simultaneously with the compressor 342.

[0716] Referring to FIG. 26(a), when the compressor 342 is driven during at least a portion of the course, the control unit 700 drives either the first heater 841 or the second heater 842 intermittently and repeatedly.

[0717] The control unit 700 may drive either the first heater 841 or the second heater 842 intermittently and repeatedly throughout the entire period in which the compressor 342 is driven, or may drive either the first heater 841 or the second heater 842 intermittently and repeatedly only during a portion of the period in which the compressor 342 is driven.

[0718] When either the first heater 841 or the second heater 842 is driven, steam is supplied into the inner case 200, causing the internal temperature to rise, and the temperature of the air flowing into the evaporator 341 also rises. Therefore, the temperature of the refrigerant flowing into the compressor 342 also rises, and the temperature of the refrigerant discharged from the compressor 342 also rises.

[0719] As a result, the pressure inside the compressor 342 also increases, and an excessive load is applied to the compressor 342.

[0720] In addition, when the refrigerant is R290 or CO2, which has a larger heat capacity than R-139, if the temperature of the refrigerant flowing into or being discharged from the compressor 342 becomes high, the reliability of the compressor 342 decreases.

[0721] In summary, when the temperature of the refrigerant discharged from the compressor 342 is low, the control unit 700 continuously drives either the first heater 841 or the second heater 842. However, when the temperature of the refrigerant discharged from the compressor 342 rises sharply or reaches a critical temperature that threatens the reliability of the compressor 342, the control unit 700 intermittently drives the first heater 841 or the second heater 842. That is, the control unit 700 drives the compressor 342 and the first heater 841. Either the first heater 841 or the second heater 842 is driven by repeatedly turning on and off.

[0722] That is, when the temperature of the refrigerant flowing into or discharged from the compressor 342 reaches a limit temperature while the first heater 841 or the second heater 842 and the compressor 342 are simultaneously driven, the control unit 700 drives the first heater 841 or the second heater 842 alternately and intermittently.

[0723] As a result, the temperature of the refrigerant discharged from the compressor 342 does not exceed the limit temperature, and the compressor 342 operates continuously. Therefore, the compressor 342 can ensure reliability throughout the entire process and prevent delays in the process.

[0724] The first heater 841 and the second heater 842 are driven simultaneously with the compressor 342 in order to quickly increase at least one of the temperature and humidity inside the inner case 200. Therefore, referring to Fig. 26(b), when the first heater 841 or the second heater 842 is driven intermittently, the driving time is set to be longer than the driving stop time.

[0725] Meanwhile, the control unit 700 controls the operation of the steam heater 840 according to the temperature inside the inner case 200 .

[0726] Specifically, when the temperature inside the inner case 200 reaches a target temperature while the first heater 841 or the second heater 842 and the compressor 842 are simultaneously driven, the control unit 700 drives the first heater 841 or the second heater 842 alternately and intermittently.

[0727] As a result, the temperature inside the inner case 200 is prevented from overheating above the target temperature, preventing thermal damage to the clothing, and the target temperature is maintained for a period longer than the sterilization time, at a temperature before the clothing is thermally damaged, thereby eradicating bacteria and mites present on the clothing.

[0728] The sterilization time is set to 10 minutes or more.

[0729] The temperature inside the inner case 200 corresponds to the temperature at the top of the inner case 200 on which the moving hanger 1000 is hung, or corresponds to the temperature of the air flowing from the inner case 200 into the circulation duct 310 .

[0730] The control unit 700 can drive the moving hanger 1000 simultaneously when the compressor 342, the first heater 841, or the second heater 842 is driven.

[0731] The control unit 700 may change the driving frequency of the moving hanger 1000 according to the amount of steam supplied to the inside of the inner case 200 and drive the moving hanger 1000 .

[0732] For example, the control unit 700 may drive the moving hanger 1000 faster when the first heater 841 is driven than when the second heater 842 is driven, thereby allowing the clothes to be more uniformly exposed to steam.

[0733] The present invention may be embodied in various forms, and the scope of the invention is not limited to the above-described embodiments. Therefore, the modified embodiments may include the elements of the claims of the present invention. If so, it should be considered to fall within the scope of the present invention.
