Description

Technical Field

[0001] The present invention relates to a clothes processing device, and more particularly to a clothes processing device capable of determining whether clothes have fallen or not by using an illumination sensor. Background Art

[0002] Generally, a clothes treating apparatus includes a washing machine that wets clothes by soaking them in water and then removes foreign matter through chemical action of detergent and physical action such as drum rotation, and a drying machine that dries the wet clothes by hot air and steam.

[0003] However, recently, a clothing care machine that can keep clothes in a dry state comfortably and cleanly without soaking them in water has been launched. Such a clothing care machine can supply steam or hot air to remove the odor of the clothes while leaving them, and perform a refresh program to dry or sterilize the clothes.

[0004] Such a clothing care machine can selectively add fragrance to the clothing, and recently, such a clothing care machine occupies an important proportion among clothing treating apparatuses together with washing machines and drying machines.

[0005] Figure 1 FIG. 1 is a diagram showing a conventional clothes treating apparatus having a steam supply unit.

[0006] Referring to Korean Patent Publication No. 10-2020-0057545, the existing clothes processing device includes: a box body 1, which forms an appearance; and an inner shell 2, which is arranged inside the box body 1 for placing clothes.

[0007] The clothes treating device may include: a circulation duct 13 for circulating the air of the inner shell 2 at the lower part of the inner shell 2; a heat exchanger 15 provided in the circulation duct 13 for exchanging heat with the air; and a compressor 14 for supplying a high-temperature refrigerant to the heat exchanger 15. In addition, a hanger portion for placing the clothes may be provided inside the inner shell 2. If the compressor 14 is driven, hot air may be supplied to the inner shell 2, and the temperature inside the inner shell 2 may be increased, so that the clothes may be dried or sterilized.

[0008] On the other hand, referring to Korean Patent Publication No. 10-2020-0065886, a clothes processing device is provided that uses a light sensor to measure the material of clothes inside an inner casing, the load amount of clothes, etc.

[0009] The conventional laundry treating apparatus determines control parameters applied to the air supply device or the steam generating device based on the estimated laundry load amount, thereby having the advantages of being able to effectively perform laundry care and shorten the time required for the care.

[0010] However, the existing clothing processing device has the following problem: when clothing falls off from the hanger portion inside the inner shell 2 during clothing processing, the user cannot identify the clothing that has fallen off the hanger during clothing processing, so the fallen clothing blocks the steam or hot air injection port and damages the clothing.

[0011] In addition, the user can only recognize that the clothes have not been properly handled due to shedding after the clothing treatment process is completed, so the user cannot take proactive measures, resulting in a problem of reduced satisfaction with the use of the product.

[0012] Therefore, a clothing processing device is available that directly detects whether clothing has fallen by installing a load sensor on a hanger, etc. However, the load sensor cannot accurately detect whether clothing has fallen due to vibrations during clothing processing and the weight of light clothing (less than 1 kg).

[0013] Therefore, it is necessary to provide a clothes treating device which can accurately determine whether clothes have fallen. Summary of the invention

[0092] The inner case 200 may be formed of a plastic resin system, or may be formed of a reinforced plastic resin system that does not deform even in air having a temperature higher than normal temperature or heated air (hereinafter, hot air), steam, or moisture.

[0093] The inner housing 200 may be configured to have a height that is longer than a width, so that the clothes can be accommodated in the accommodation space 220 in an undone or wrinkled state.

[0094] The laundry treating apparatus 1 of the present invention may include a placing portion 500 capable of placing laundry in the accommodation space 220 of the inner housing 200 .

[0095] The placement portion 500 may include a hanger portion 510 , which is disposed on an upper surface of the inner housing 200 and is used to place clothes thereon.

[0096] If the clothes are placed on the hanger portion 510 , the clothes may be arranged in a state of being suspended in the air within the storage space 220 .

[0097] On the other hand, the placement portion 500 may further include a pressurizing portion 520 coupled to the inner surface of the door 40 and capable of fixing the clothes.

[0098] The hanger portion 510 may also have a strip shape arranged along the width direction of the inner housing 200, and may support a hanger for placing clothes. In addition, as shown in the figure, the hanger portion 510 may have a hanger shape, and clothes may be placed directly thereon.

[0099] The clothes treating apparatus of the present invention may further include a vibrating portion, and the vibrating portion can remove foreign matter such as dust attached to the clothes by vibrating the hanger portion 510 .

[0100] The placing part 500 may include a pressurizing part 520, which is disposed on the door 40 and can press and fix the clothes. The pressurizing part 520 may include: a supporting part 522, which is fixed to the inner surface of the door 40 and supports one side of the clothes; and a pressing part 521, which presses the clothes supported by the supporting part 522.

[0101] The pressing portion 521 may be disposed to move toward or away from the supporting portion 522. For example, the pressing portion 521 may be rotatably disposed on the supporting portion 522 or the inner surface of the door 40.

[0102] Thus, the pressing portion 521 and the supporting portion 522 can remove wrinkles of the clothing by pressing both sides of the clothing, and can also generate desired creases.

[0103] The clothes treating apparatus of the present invention may include a machine room 300 that supplies at least one of hot air and steam to the accommodating space 220 , or may be provided with various devices capable of purifying or dehumidifying the external air of the housing 100 .

[0104] The machine room 300 may be configured to be separated or partitioned from the inner case 200 and communicate with the inner case 200 .

[0105] The machine room 300 may be disposed at a lower portion of the inner case 200. Thus, if hot air and steam having a small specific gravity are supplied to the inner case 200, the hot air and steam may be naturally supplied to the clothes.

[0106] The machine room 300 may include a heat supply part 340 capable of supplying hot air to the inside of the inner case 200. The heat supply part 340 may be formed by a heat pump system or may be formed by a heater that directly heats air using electric energy.

[0107] In the case where the heat supply part 340 is formed of a heat pump system, the air exhausted from the inner case 200 may be dehumidified and heated again and supplied to the inner case 200. A detailed structure of the heat supply part 340 will be described later.

[0108] The machine room 300 may include a steam supply part 800 capable of supplying steam to the inside of the inner case 200. The steam supply part 800 may directly supply steam to the inside of the inner case 200. A detailed structure of the steam supply part 800 will be described later.

[0109] To this end, the inner housing 200 may have a plurality of through holes 230 penetrating through one surface and communicating with the machine chamber 300 .

[0110] The air of the accommodation space 220 may be supplied to the machine room 300 through the through hole 230 , and at least one of hot wind and steam generated in the machine room 300 may be supplied to the accommodation space 200 .

[0111] The through hole 230 may include: an inlet hole 231, which passes through the lower surface of the inner shell 200, for the air inside the inner shell 200 to be discharged or sucked into the machine room 300; and an outlet hole 232, which passes through the lower surface of the inner shell 200, for the hot air generated in the machine room 300 to be discharged.

[0112] The discharge hole 232 may be disposed in the lower surface of the inner case 200 toward the rear surface. For example, the discharge hole 232 may be disposed between the lower surface or the rear surface of the inner case 200 and inclined to the ground, and disposed toward the hanger portion 510 .

[0113] In addition, the inflow hole 231 may be disposed biased forward in the lower surface of the inner housing 200 . Thus, the inflow hole 231 may be disposed apart from the discharge hole 232 .

[0114] The through hole 230 may include a steam hole 233 to which the steam generated in the steam supply part 800 is supplied. The steam hole 233 may be disposed at one side of the discharge hole 232.

[0115] On the other hand, a water supply tub 3 capable of supplying water to the steam supply part 800 and a drain tub 4 for collecting condensed water condensed in the heat supply part 340 may be provided in front of the machine room 300 .

[0116] The water supply tub 3 and the drainage tub 4 may be detachably disposed in front of the machine room 300. Thus, the laundry processing apparatus 1 of the present invention may be freely disposed without being restricted by a water supply source or a drainage source.

[0117] On the other hand, a drawer 5 leading out and leading in to the front and having a separate accommodation space can also be provided in front of the machine room 300. The drawer 5 can also store a steam generating device or an iron.

[0118] Figure 3 It is a diagram showing the upper structure of the inner casing.

[0119] The hanger part 510 of the clothes treating apparatus of the present invention may include a power transmission part 513 , and the power transmission part 513 is disposed on the upper part of the inner housing 200 to shake the hanger 511 .

[0120] A hanging portion 512 for placing or resting the hanger 511 may be provided at the lower portion of the power transmission portion 513 .

[0121] Thus, when the power transmission part 513 moves, the hanging part 512 moves, which can have an effect of shaking the hanger 511 placed on the hanging part 512 and causing the clothes to vibrate.

[0122] There may be a plurality of the power transmission parts 513, and there may also be a plurality of the hanging parts 512 coupled to the power transmission parts 513. Thus, a large number of clothes corresponding to the number of the power transmission parts 513 can be placed inside the inner case 200 and refreshed.

[0123] Figure 3 The hanger portion 510 and the power transmission portion 513 are shown based on a case where they are arranged along the width direction of the inner housing 200 .

[0124] The hanger 510 and the power transmission unit 513 may be arranged along the direction in which the clothes are arranged in the storage space. For example, if the clothes are arranged in the front-to-back direction in the inner shell 200, the hanger 510 and the power transmission unit 513 may be arranged in the front-to-back direction of the inner shell 200.

[0125] The following description will be based on the case where the hanger portion 510, the plurality of power transmission portions 513, and the plurality of hanging portions 512 are arranged along the width direction of the inner shell 200, but this is only one embodiment. The hanger portion 510, the plurality of power transmission portions 513, and the plurality of hanging portions 512 can be arranged along the designed direction so as to place or arrange a plurality of clothes in the storage space.

[0126] The hanger part 510 may further include a driving part 514 for providing power to move the power transmission part 513 .

[0127] As long as the driving part 514 can transmit power to the power transmission part 513, the driving part 514 may be exposed to the inside of the inner housing 200. However, since the driving part 514 is configured to operate by receiving electric energy, it is preferable to prevent the driving part 514 from being exposed to steam or hot air.

[0128] The driving unit 514 is disposed between the upper surface of the inner housing 200 and the box body 10 , thereby preventing the driving unit 514 from being exposed to the accommodation space 210 .

[0129] The power transmission part 513 may penetrate the upper portion of the inner housing 200 and receive power from the driving part 514. The power transmission part 513 may penetrate the upper portion of the inner housing 200 and extend downward, so that the lower end of the power transmission part 513 may be exposed to the accommodation space 210.

[0130] The power transmission part 513 may have a rod shape, a tube shape, a plate shape, or the like formed so that its length is longer than its thickness.

[0131] Figure 4 2 is a diagram showing the structure of a machine room of the clothes treating apparatus according to the present invention.

[0132] Figure 4 (a) is a view of the machine room 300 viewed from the front. Figure 4 (b) is a diagram of the machine room 300 as viewed from the rear.

[0133] A plurality of components for supplying hot air to the clothes processing space, circulating the air in the clothes processing space, supplying steam to the clothes processing space, or purifying the air outside the cabinet may be disposed inside the machine room 300 .

[0134] The machine room 300 may include a base portion 310, and the base portion 310 is configured to support or install a space for various devices. The base portion 310 may provide an area for installing various devices.

[0135] The base portion 310 may be provided with a circulation duct 320 through which air flowing in from the inner case 200 or the outside of the housing 100 moves.

[0136] The circulation duct 320 may have a shell shape with an open top surface, and may include a portion of the heat supply unit 340 disposed therein.

[0137] When the heat supply unit 340 is formed of a heat pump system, the circulation pipe 320 may include heat exchangers 341 and 343 described later and a compressor 342 for supplying a high-temperature and high-pressure refrigerant to the heat exchangers.

[0138] The heat exchangers 341 and 343 may be accommodated in the circulation duct 320 , and may cool and dehumidify the air flowing through the circulation duct 320 , or may generate hot air by heating the air.

[0139] In the case where the circulation duct 320 draws air from outside the housing 100 , an external air duct 370 for drawing external air may be provided in front of the circulation duct 320 .

[0140] The circulation duct 320 may be arranged to communicate with the external air duct 370 to selectively inhale external air.

[0141] The water supply bucket and the drainage bucket may be detachably coupled to the front of the circulation duct 320. The water supply bucket 3 and the drainage bucket 4 may be disposed on the upper portion of the external air duct 370.

[0142] The circulation duct 320 may be combined with the base portion 310, or may be integrally provided with the base portion 310. For example, the base portion 310 and the circulation duct 320 may be manufactured by injection molding.

[0143] The machine room 300 may include a base cover 360 disposed to communicate with the circulation pipe 320 and the inflow hole 231 .

[0144] The base cover 360 may be configured to be coupled to an upper portion of the circulation duct 320 to guide the air sucked from the inflow hole 231 into the circulation duct 320 .

[0145] The base cover 360 may block the air inside the circulation duct 320 from being discharged to the outside by shielding the upper surface of the circulation duct 320. The lower portion of the base cover 360 and the upper surface of the circulation duct 320 may form one side of the flow path of the circulation duct 320.

[0146] The base cover 360 may include an inflow portion 362 connecting the inflow hole 231 and the circulation duct 320. The inflow portion 362 has a duct shape, and thus may function as an air intake duct that transfers air inside the inner case 200 to the circulation duct 320.

[0147] The machine room 300 may be provided with a steam supply unit 800 connected to the water supply tub 3 to receive water to generate steam and supply the steam to the inner case 200. The steam supply unit 800 may be disposed on an upper portion of the base cover 360.

[0148] The steam supply part 800 may be disposed behind the inflow part 362 .

[0149] The machine room 300 may include a fan installation part 350 configured to communicate the circulation duct 320 and the inner housing 200. The fan installation part 350 may include: an air supply fan 353 providing power to move the air inside the circulation duct 320 in one direction; and a fan cover 351 accommodating the air supply fan 353, which is combined with the circulation duct 320 or extends in the circulation duct 320.

[0150] The fan installation portion 350 may further include an exhaust duct 352 configured to communicate with the circulation duct 320 and the exhaust hole 232 .

[0151] The exhaust duct 352 may be formed to extend from the lower portion of the fan cover 351 toward the exhaust hole 232 such that a cross-sectional shape and a cross-sectional area thereof have a cross-sectional shape and an area corresponding to those of the exhaust hole 232 .

[0152] As a result, air inside the inner case 200 may flow in through the base cover 360 and be supplied again to the inside of the inner case 200 through the fan installation part 350 after passing through the circulation duct 320 .

[0153] Figure 5 The base 310 may be provided with a compressor installation portion 313, and the compressor installation portion 313 is provided with the compressor 342 that supplies refrigerant to the heat exchangers 341 and 343. The compressor installation portion 313 may be arranged outside the circulation duct 320.

[0154] In addition, the base portion 310 may be provided with a control portion or a control panel C for controlling the laundry treating apparatus of the present invention.

[0155] The base portion 310 may be provided with a control portion installation portion 313 forming a space in which the control portion C can be inserted at a lower portion of the circulation duct 320 .

[0156] The control unit C may control all components that electronically control the compressor 342 , the steam supply unit 800 , the air supply fan 353 , and the like.

[0157] Since the control unit C is inserted and supported by the base 310, vibration or impact applied to the control unit C can be buffered. In addition, the control unit C is arranged close to all electronic components, so that the occurrence of control errors such as noise can be minimized.

[0158] In addition, a steam supply part is disposed at the upper portion of the circulation duct 320, and a control part C is disposed at the lower portion of the circulation duct 320. Therefore, the circulation duct 320 may be provided in a straight duct shape between the steam supply part 800 and the control part C. Therefore, the flow path resistance of the air passing through the circulation duct 320 may be minimized.

[0159] The circulation duct 320 , the external air duct 370 , the steam supply part 800 , the control part C, and the heat supply part 340 may be provided on the base part 310 in a module form.

[0160] Thus, the base portion 310 can be introduced into and taken out of the machine room 300 to the front or rear, thereby facilitating installation and maintenance.

[0161] Figure 5 (a) is a three-dimensional view of the base portion 310 viewed from the front, Figure 5 (b) and Figure 5 (c) is a stereoscopic view of the base portion 9310 as viewed from the rear.

[0162] The base portion 310 may be disposed above a base plate forming a lower surface of the laundry treating apparatus. The base portion 310 itself may form a lower surface of the laundry treating apparatus.

[0163] The base portion 310 may include a base bottom 311 forming a support surface. The base bottom 311 may form a lower surface of the laundry treatment device. In addition, the base bottom 311 may be disposed on an upper surface of the bottom surface of the housing 100 forming the lower surface of the laundry treatment device.

[0164] The base portion 310 may be integrally provided with the circulation duct 320 forming at least a portion of a flow path for air movement. The circulation duct 320 may be formed to extend upward from the base bottom portion 311 .

[0165] The circulation duct 320 may include: a duct body 321 extending from the base bottom 311 to form a flow path; a heat exchanger setting portion 3212 providing a space for setting an evaporator 341 or a condenser 343 inside the duct body 321; and an air exhaust portion 323, arranged at the rear of the duct body 321 for exhausting air from the duct body 321.

[0166] The air discharge portion 323 may have a tube shape extending rearward from the duct body 321 . A diameter of the air discharge portion 323 may be smaller than a width of the duct body 321 .

[0167] The air discharge portion 323 may be connected to the fan cover 350 . The air discharged from the air discharge portion 323 may be guided to the inside of the inner housing 200 through the fan cover 350 .

[0168] The circulation duct 320 may include an external air suction portion 322 formed through a front surface of a duct body 321 .

[0169] The external air intake portion 322 may be communicated with the external air duct 370. The external air duct 370 may be disposed and supported in front of the external air intake portion 322.

[0170] The circulation duct 320 may include a damper for opening and closing the external air suction portion 322. By opening and closing the damper, the external air may be allowed or blocked to flow into the circulation duct 320.

[0171] The base portion 310 may include a compressor installation portion 312 providing a space for installing the compressor 342. The compressor installation portion 312 may be formed at one side of the base bottom portion 311 and may be formed integrally with the base bottom portion 311.

[0172] The compressor installation portion 312 may also be formed with a protrusion capable of supporting the compressor 342. The compressor installation portion 312 may be disposed toward the rear of the base portion 310. The compressor installation portion 312 may be disposed to overlap at least a portion with the air discharge portion 323 in the width direction.

[0173] The compressor installation portion 312 may be provided with a buffer member that reduces vibration transmitted from the compressor 342. The buffer member may be fixed to the protrusion.

[0174] The base portion 310 may include a control portion installation portion 313 where the control portion C is installed. The control portion installation portion 313 may be formed between the base bottom portion 311 and the circulation duct 320. The control portion installation portion 313 may be formed between the base bottom portion 311 and the bottom surface of the circulation duct 320. The control portion installation portion 313 may have a duct shape that is open at one of the front and rear of the lower portion of the circulation duct 320.

[0175] The structure of the control section setting section 313 will be described later.

[0176] Figure 6 2 is a diagram showing a circulation duct structure of a clothes treating apparatus according to the present invention.

[0177] The circulation duct 320 may extend from the bottom of the base to the top to form a flow path for air flow. The circulation duct 320 may include a heat exchanger installation part 3212 providing a space for installing the evaporator 341 and the condenser 343. The heat exchanger installation part 3212 may be installed inside the duct body 321.

[0178] The upper surface of the duct body 321 may be open. The condenser 343 and the evaporator 341 may be inserted and installed through the opening of the duct body 321 .

[0179] The opening of the duct body 321 may be shielded by the base cover 360 , and the base cover 360 and the duct body 321 may form a flow path of the circulation flow path 320 .

[0180] The front surface of the duct body 321 may be arranged to be spaced apart from the front end of the base bottom 311 toward the rear.

[0181] Thus, the base bottom 311 can ensure that a support surface 3111 of at least one of the water supply bucket 3 or the drainage bucket 4 and the external air duct 370 is provided and supported.

[0182] On the other hand, the heat supply unit 340 may include: an evaporator 341, which is a heat exchanger arranged inside the circulation pipe 320 and cools and dehumidifies the air flowing into the circulation pipe 320; a condenser 343, which is a heat exchanger that heats the air passing through the evaporator 341 and forms hot air; a compressor 342, which supplies a refrigerant for heat exchange with the air to the condenser 343 and is arranged outside the circulation pipe 320; and an expansion valve 344, which expands and cools the refrigerant passing through the condenser 343.

[0183] On the other hand, since the duct body 321 and the base portion 310 are integrally formed, the height of the heat exchanger installation portion 3212 can be further ensured, and the heights of the condenser 343 and the evaporator 341 can also be increased.

[0184] As a result, the width of the condenser 343 and the evaporator 341 in the front-rear direction can be reduced, thereby reducing the number of refrigerant pipes passing through the condenser and the evaporator. This has the effect of reducing the flow loss of air passing through the condenser and the evaporator.

[0185] On the other hand, the sum of the length of the evaporator 341 and the length of the condenser 343 may be less than the length of the heat exchanger setting portion 3212. Thus, the front-to-back length of the heat exchanger setting portion 3212 may be the same as or less than half the length of the duct body 321.

[0186] Therefore, the heat exchanger installation portion 3212 can be sufficiently separated from the external air suction portion 322 , and thus a sufficient space for the external air and the air inside the inner case 200 to flow in can be ensured inside the circulation duct 320 .

[0187] On the other hand, the interior of the duct body 321 may include a setting partition wall 3211 that separates the heat exchanger setting part 3212 from the outside of the heat exchanger setting part 3212. The setting partition wall 3211 may protrude from the side of the duct body 321 to support the front of the evaporator 341.

[0188] In addition, the width of the duct body 321 may be expanded based on the partition wall 3211 and extend rearward.

[0189] As a result, the width of the heat exchanger installation portion 3212 may be greater than half the width of the base portion 310 . In addition, the width of the circulation duct 320 may be greater than half the width of the base portion 310 .

[0190] The width of the condenser 343 and the width of the evaporator 341 may also be greater than half of the entire width of the base portion 310 .

[0191] As described above, if the widths of the condenser 343 and the evaporator 341 are ensured, there is an effect that the heat exchange capacity can be sufficiently ensured.

[0192] In addition, the fan cover 350 can be arranged to overlap with the condenser 343 or the evaporator 341 in the front-to-back direction. Therefore, the air passing through the evaporator 341 and the condenser 343 can flow into the fan cover 350 without bending the flow path. That is, the air flowing into the circulation duct 320 does not bend the flow path in the process of moving to the fan cover, which has the effect of minimizing flow loss.

[0193] Figure 7 The shape of the circulation duct of the clothes treating apparatus of the present invention will be described.

[0194] The base portion 310 may be formed by injection molding so that the base bottom 310 and the circulation flow path 320 are integrally formed.

[0195] The mold for molding the inner surface of the duct body 321 can be drawn out and removed upward from the inside of the duct body 321. At this time, the wall surface of the duct body 321 can be inclined at a predetermined angle relative to the removal direction of the mold to easily draw out the mold.

[0196] The width of the lower surface 321 a of the duct body 321 may be greater than the width of the upper surface 321 b of the duct body 321 .

[0197] Specifically, the distance between the wall surfaces of the duct body 321 facing each other can be formed to increase as the distance from the base bottom 311 increases. The distance between the left side and the right side of the circulation flow path facing each other can increase along the lead-out direction of the mold. Thus, the removal of the mold can be facilitated.

[0198] On the other hand, the air discharge part 323 may include an air extension pipe 3231 extending from the rear of the duct body 321 with a reduced diameter or width, and an air discharge pipe 3232 extending from the air extension pipe 3231 in a pipe shape with a uniform diameter and forming a hollow 3233 inside. The air extension pipe 3231 may perform the function of a nozzle, thereby increasing the speed of the discharged air.

[0199] In addition, the mold for molding the air discharge portion 323 can be removed as shown in the figure above. After being led forward from the inside of the air discharge portion 323 toward the inside of the circulation flow path 320, it can be removed toward the upper open surface of the circulation flow path 320. It can be formed by a structure that makes it easy to lead out the mold in the above process.

[0200] Figure 8 A cross-sectional view of the circulation conduit is shown.

[0201] The partition wall 3211 may be protruded inward from the inner wall of the pipe body 321 or the outer wall of the circulation pipe may be recessed inward.

[0202] The heat exchanger installation portion 3212 may be formed between the heat exchanger installation partition wall 3211 and the air discharge portion 323 .

[0203] The mold for molding the air discharge portion 323 may be led out to the upper portion and removed after being led out to the front of the air discharge portion 323. It is necessary to prevent the mold for molding the air discharge portion 323 from interfering with the partition wall provided in the heat exchanger when being led out to the front from the inside of the air discharge portion 323. To this end, the design value of the air discharge portion 323 may be adjusted.

[0204] Specifically, when the air discharge portion 323 is molded, a mold for molding the front side and a mold for molding the rear side can be separately set based on the parting line 3233 of the air discharge portion 323 in the figure. Thus, the removal directions of the molds can also be different from each other. The mold formed in the front part based on the parting line of the air discharge portion 323 can be led out to the front, and the mold formed in the rear part based on the parting line of the air discharge portion 323 can be led out to the rear.

[0205] That is, in order to prevent the mold drawn forward from interfering with the partition wall set for the heat exchanger during the drawing process, in the drawings, the distance 1 321a may be smaller than the distance 2 321c. The distance 1 321a may refer to the distance between the parting line of the air discharge portion 323 and the front end of the air discharge portion 323. In addition, the distance 1 321a may refer to the distance between the parting line of the air discharge portion 323 and the rear opening of the circulation duct. The distance 2 321c may refer to the distance between the front end of the air discharge portion 323 and the partition wall set for the heat exchanger. In addition, the distance 2 321c may refer to the distance between the rear opening of the circulation duct and the partition wall set for the heat exchanger.

[0206] Fig. 9 1 is a diagram showing a structure of a control unit installation portion provided on a base of a clothes treating apparatus according to the present invention.

[0207] Fig. 9 (a) is a diagram showing a state in which the control unit C is installed in the control unit installation portion 313.

[0208] The control unit C can be configured to control all devices required for the laundry processing device of the present invention to execute any process of the laundry refreshment program. The control unit C can be formed by a PCB substrate, but is not limited thereto, and can be formed by various devices for control.

[0209] The control unit C may be inserted into and placed in the control unit setting portion 313 .

[0210] The control unit installation portion 313 may be disposed at a lower portion of the circulation pipe 320 .

[0211] The bottom surface of the circulation duct 320 may form the top surface of the control unit installation portion 313. The control unit installation portion 313 may be disposed at a lower position than the air discharge portion 323.

[0212] The control part installation part 313 may be formed integrally with the base bottom 311. The control part installation part 313 may form a recessed space at the lower part of the circulation duct during the process of molding the circulation duct 320 in the base part 310.

[0213] The control part C may be introduced into the control part installation part 313 in a manner of sliding from the rear to the front.

[0214] A bracket 3131 surrounding the control part may be further provided on the surface of the control part C. The bracket 3131 may be disposed on the upper part and the lower part of the control part, so as to prevent foreign matter from flowing into the control part.

[0215] In addition, the bracket 3131 can prevent heat or vibration from being transferred to the control part C and damaging the circuit substrate inside the control part C. The bracket 3131 can be formed of a metal material.

[0216] Fig. 9 (b) is a diagram showing a state in which the control unit is set in the control unit setting unit.

[0217] As shown in the above figure, the control part C can be set to form a specified angle with the base bottom 311.

[0218] For example, the control portion C may be configured to be inclined toward the water storage portion 326. Thus, when water flows out to the upper portion of the control portion C, the water may quickly escape from the control portion C, and the bottom surface of the circulation pipe 320 may be formed to be inclined toward the water storage portion 326.

[0219] The control portion C may include a support member 3132 that is formed to protrude toward the side.

[0220] The control unit setting portion 313 may include ribs 3134 protruding from both sides of the setting portion. The support member 3132 of the control unit may be placed on the upper side of the ribs 3134.

[0221] The support member 3132 of the control part may support the entire load of the control part C. If the support member 3132 of the control part is supported on the upper side of the rib 3134 , the control part C may be spaced apart from the base bottom 311 by a predetermined distance.

[0222] The ribs 3134 may be formed integrally with the base portion 310. The ribs 3134 are formed together when the base portion 310 is injection molded, and may be integrally provided with the base bottom portion 311, the circulation pipe 320, and the like.

[0223] A protrusion 3133 may be provided on the front side of the control unit C. In addition, a guide protruding toward the rear may be provided on the inner side of the control unit setting portion 313. The protrusion may be combined with the guide. The protrusion may be inserted into the guide. When the control unit is introduced into the control unit setting portion, the control unit may be aligned to an accurate position by combining the protrusion with the guide.

[0224] In addition, as described above, the two sides of the control part can be positioned in a manner that the support members are placed on the ribs. Using the above-described coupling process, the control part can be coupled to the exact position of the control part setting part without additional fastening members.

[0225] Fig.10 FIG. 1 is a diagram showing the structure of the air exhaust portion 323 of the clothes treating apparatus of the present invention.

[0226] The base portion 310 may include an air discharge portion 323 for discharging the processed air toward the fan housing.

[0227] The air discharge portion 323 may be configured to connect the interior of the circulation duct 320 or the duct body 321 to the fan cover 350. The air discharge portion 323 may have a bell mouth shape. Due to the bell mouth shape, the flow loss of air can be reduced and the air circulation efficiency can be improved.

[0228] The air exhaust pipe 3232 of the air exhaust portion 323 has a tube shape. In the process of removing the mold based on the parting line 3233, the mold arranged in front of the parting line 3233 can be led out forward, and the mold arranged behind the parting line 3233 can be led out backward.

[0229] The fan installation portion 350 may be coupled to and supported by the air outlet pipe 3232. The fan cover 351 may have a coupling hole coupled to the outer peripheral surface of the air outlet pipe 3232, and the air supply fan 353 may be disposed in the coupling hole.

[0230] The fan cover 351 may include an exhaust duct 352 extending from an outer circumferential surface or an outer side of the air supply fan 353 toward the exhaust hole 232 .

[0231] The fan cover 351 and the exhaust duct 352 may house the air supply fan 353 therein and form a flow path through which air may flow.

[0232] A motor for rotating the air supply fan 353 may be coupled to and supported on the outside of the fan cover 351 .

[0233] Fig.11 1 is a diagram showing the structure of a base cover of a clothes treating apparatus according to the present invention.

[0234] The base cover 360 may be configured to be combined with an upper surface of the circulation duct 320 to prevent the inside of the circulation duct 320 from being exposed.

[0235] The base cover 360 may include: an inflow body 361 combined with an upper surface of the circulation duct 320 to connect the inner shell 200 and the circulation duct 320 ; and a shielding body 363 extending from the inflow body 361 to shield the circulation duct 320 .

[0236] The inflow body 361 may have a pipe shape so that the inflow hole 231 of the inner case communicates with the inside of the circulation pipe 320. The inflow body 361 may protrude more upward than the shielding body 363.

[0237] The inflow body 361 may be disposed at a position further forward than the evaporator 341 so as not to face the evaporator 341 and the condenser 343 , and may be disposed at a position further forward than the partition wall 3211 .

[0238] The inflow body 361 may function as an inflow duct for moving the air in the inner casing 200 toward the circulation duct 320 .

[0239] The inflow body 361 may be provided with an inflow portion 362 therein through which the air of the inner housing 200 can pass.

[0240] Specifically, the base cover 360 may include: a first rib 362 a extending along the width direction of the inflow body 361 ; and a second rib 362 b spaced rearward from the first rib 362 a and extending along the width direction of the inflow body 361 .

[0241] The first rib 362a and the second rib 362b may be arranged in parallel. The first rib 362a and the second rib 362b may have a plate shape extending in a vertical direction, and the height may correspond to the height of the inflow body 361.

[0242] The front surface of the inflow body 361 and the first rib 362a may form a first inflow port 3621 , the first rib 362a and the second rib 362b may form a second inflow port 3623 , and the second rib 362b and the rear surface of the inflow body 361 may form a third inflow port 3622 .

[0243] The first inlet 3621 and the third inlet 3622 may have the same area as each other, and the second inlet 36222 may be smaller in area than the first inlet 3621 and the third inlet 3622 .

[0244] The base cover 360 may include a damper portion 364 for opening and closing the inflow portion 362 , and a driving portion 365 coupled to the damper portion 364 to control the opening and closing of the damper portion 364 .

[0245] The damper portion 364 may include: a first damper portion 3641 for opening and closing the first inlet 3621 ; and a second damper portion 3642 for opening and closing the third inlet 3622 .

[0246] The first damper portion 3641 may have a plate shape provided with an area corresponding to the first inlet 3621 , and may be rotatably coupled to both side surfaces of the inlet body 361 inside the first inlet 3621 .

[0247] The second damper portion 3642 may have a plate shape provided with an area corresponding to the third inlet 3622 , and may be rotatably coupled to both side surfaces of the inlet body 361 inside the third inlet 3622 .

[0248] The second inlet 3623 may be provided with a blocking filter 366 , and the blocking filter 366 allows air to pass through but can filter foreign matter such as dust and fluff.

[0249] The blocking filter 366 may be inserted into the second inlet 3623 to divide the first inlet 3621 and the third inlet 3622. The blocking filter 366 may extend in contact with the bottom surface of the circulation duct 320 at the second inlet 3623.

[0250] The blocking filter 366 may be a filter capable of filtering the moisture. For example, the blocking filter 366 may be a high efficiency air (HEPA) filter or the like.

[0251] On the other hand, the second inlet 3623 may be further combined with a shielding member that shields the second inlet 3623 when the blocking filter 366 is inserted.

[0252] The driving part 365 may include: a motor providing power to selectively rotate the first damper part 364 and the second damper part 365; and a plurality of gear components engaged with the motor to rotate, so as to selectively rotate the first damper part 364 and the second damper part 365.

[0253] Due to the driving unit 365 , the first inlet 3611 and the third inlet 3622 may be selectively opened.

[0254] Due to the driving unit 365 , the air contained in the inner shell 200 may flow into the circulation duct 320 along the first inlet 3621 or into the circulation duct 320 along the third inlet 3622 .

[0255] Of course, the driving unit 365 can control the first damper 3641 and the second damper 3642 to open the first inlet 3611 and the third inlet 3622 , and control the first damper 3641 and the second damper 3642 to cover the first inlet 3611 and the third inlet 3622 .

[0256] The driving unit 365 may be any structure as long as it can rotate the first damper 3641 and the second damper 3642. For example, it may be a combination of a motor, a driving gear rotated by the motor, and a driven gear coupled to the first damper and the second damper and rotated by the rotation of the driving gear.

[0257] The base cover 360 may include a shielding body 363 extending from the inflow body 361 and capable of shielding the evaporator 341 and the condenser 343. The shielding body 363 may have a plate shape.

[0258] The base cover 360 may be detachably coupled to the upper surface of the circulation duct 320 via an inflow hook 3612 extending from the lower surface of the inflow body 361 .

[0259] The circulation pipe 320 may include a coupling portion detachably coupled to the inflow hook 3612 .

[0260] Fig.12 It is a diagram showing the structure of an external air duct.

[0261] Reference Fig.12 (a), the external air duct 370 may be combined with the base portion 310 .

[0262] The external air duct 370 may communicate with the external air suction part 322 .

[0263] The external air duct 370 may include an external air damper 373 for opening and closing the external air suction part 322 , and an external air driving part 374 for controlling to selectively open the external air suction part 322 by rotating the external air damper 373 .

[0264] The external air damper 373 may have a plate shape capable of sealing the external air intake portion 322 , and may be rotatably coupled to both side surfaces of the external air intake portion 322 .

[0265] The external air driving part 374 may be an actuator coupled to the external air duct 370 or the circulation duct 320 to rotate the external air damper 373 .

[0266] The external air duct 370 may include an extension duct 372 extending forward from the external air suction portion 322 in front of the external air suction portion 322 , and an air suction duct 371 extending forward from the extension duct 372 into which external air can flow.

[0267] The air intake duct 371 may extend from the lower portion of the extension duct 372 , and may be provided with a water supply bucket 3 and a water discharge bucket 4 at the upper portion. The water supply bucket 3 and the water discharge bucket 4 may also be combined or placed in the air intake duct 371 .

[0268] The air intake duct 371 may include: an external air port 3711 for external air intake at one end or a free end; and a partition rib 3712 for partitioning the external air port 3711 .

[0269] The external air port 3711 may be disposed at a lower position than the door 40 to prevent the external air port 3711 from being blocked by the door 40 .

[0270] The partition rib 3712 may partition the interior of the external air port 3711 to prevent foreign matter or a user's body from entering.

[0271] Reference Fig.12 (b), if the external air driving unit 374 rotates the external air damper 373 to open the external air suction unit 322, the air suction duct 371 and the circulation duct 320 may be communicated with each other.

[0272] At this time, if the air supply fan 352 is driven, the air outside the cabinet may flow into the circulation duct 320. If the compressor 342 is driven, the external air may be dehumidified while passing through the circulation duct 320 and supplied to the inside of the inner case 200.

[0273] The door 40 may further include: an exhaust port for exhausting the air inside the inner housing 200 to the outside; and an exhaust damper for selectively opening and closing the exhaust port. The exhaust port may be disposed to face the accommodation space of the inner housing 200.

[0274] Thereby, the dehumidified air can be discharged through the discharge port.

[0275] In addition, the external air may be filtered while passing through the blocking filter 366 and discharged to the outside of the housing 100 again.

[0276] Fig.13 It is a diagram showing the flow of air flowing through the circulation duct.

[0277] Reference Fig.13 (a) can be controlled so that the external air damper 373 blocks the external air intake portion 322 , the first damper 3641 opens the first inlet 3621 , and the second damper 3642 blocks the third inlet 3622 .

[0278] When the air supply fan 352 is driven, the air inside the inner housing 200 may flow into the first inlet 3621 and be filtered while passing through the blocking filter 366 .

[0279] If the compressor 342 is driven, the air passing through the blocking filter 366 may be dehumidified and heated while passing through the evaporator 341 and the condenser 343 .

[0280] The air passing through the heat exchanger may be supplied to the inside of the inner case 200 via the fan installation part 350 .

[0281] This state may be a state in which steam is not supplied to the inner case 200. This is because, if steam is supplied to the inner case 200, the moisture wets the blocking filter 366, and thus the performance of the blocking filter 366 cannot be guaranteed.

[0282] As a result, when steam is not supplied to the inner shell 200 or when the humidity is low before or after steam is supplied to the inner shell 200, the air inside the inner shell 200 can pass through the first inlet 3641 and foreign matter such as fluff can be filtered out through the blocking filter 366.

[0283] Reference Fig.13(b) can be controlled so that the external air damper 373 blocks the external air intake portion 322 , the first damper 3641 blocks the first inlet 3621 , and the second damper 3642 opens the third inlet 3622 .

[0284] When the air supply fan 352 is driven, the air inside the inner housing 200 may flow into the third inlet 3622 . The third inlet 3622 may be disposed downstream of the blocking filter 366 , so the air flowing into the third inlet 3622 may not pass through the blocking filter 366 .

[0285] If the compressor 342 is driven, the air passing through the blocking filter 366 may be dehumidified and heated while passing through the evaporator 341 and the condenser 343 .

[0286] The air passing through the heat exchanger may be supplied to the inside of the inner case 200 via the fan installation part 350 .

[0287] As a result, when steam is supplied to the inner shell 200 or the humidity inside the inner shell 200 is very high, the air in the inner shell 200 can flow into the third inlet 3622 and prevent the blocking filter 366 from being exposed to moisture by blocking the flow into the first inlet 3621.

[0288] Reference Fig.13 (c) can be controlled so that the external air damper 373 opens the external air intake portion 322 , the first damper 3641 blocks the first inlet 3621 , and the second damper 3642 blocks the third inlet 3622 .

[0289] When the air supply fan 352 is driven, the air inside the inner housing 200 can be blocked from flowing into the inlet portion 362, so that only the air outside the housing 100 flows into the circulation duct 320 and passes through the blocking filter 366. Thus, foreign matter such as dust contained in the external air can be filtered in the blocking filter 366.

[0290] If the compressor 342 is driven, the air passing through the blocking filter 366 may be dehumidified while passing through the evaporator 341 and the condenser 343 .

[0291] The air passing through the heat exchanger may be supplied to the inside of the inner case 200 via the fan setting part 350 and supply fresh hot air to the clothes.

[0292] At this time, when the door 40 is provided with a device for discharging the air inside the inner shell 200 to the outside, the air outside the box can be purified while passing through the blocking filter 366 and the heat supply part 340, and discharged in a dehumidified state.

[0293] As a result, in the laundry processing apparatus of the present invention, the control unit C can determine the flow directions of the air inside the inner shell 200 and the air outside the box by controlling the external air driving unit 374 and the inflow driving unit 365 .

[0294] Fig.14 It is a diagram showing the installation structure of the steam supply unit.

[0295] The steam supply part 800 may be mounted and supported on the base cover 360 .

[0296] The steam supply unit 800 may include a steam housing 810 disposed on the base cover 360 and storing water for generating the steam.

[0297] The steam supply part 800 may further include a mounting bracket 870 capable of fixing the steam housing 810 to the base cover 360 .

[0298] The mounting bracket 870 may be coupled to the base cover 360 and fix the steam housing 810 .

[0299] The mounting bracket 870 may include: a lower panel 871 supporting the lower surface of the steam housing 810 ; and side panels 872 supporting both side surfaces of the steam housing 810 at the lower panel 871 .

[0300] The mounting bracket 870 may further include one or more securing clips 873 extending from the side panel 872 and preventing the steam housing 810 from being disengaged.

[0301] The fixing clip 873 may be detachably disposed on the upper portion or side of the steam housing 810 .

[0302] The compressor 342 may be disposed at a lower position than the steam supply part 800 .

[0303] The bracket 870 may block heat generated in the compressor or heat generated by the refrigerant compressed in the compressor from being transferred to the steam supply part 800 .

[0304] When a fire occurs in the compressor 342 , the bracket 870 may further block the fire from transferring to the steam supply unit 800 .

[0305] On the other hand, the base cover 360 may include a fastening portion 3631 provided on the shielding body 363 and detachably combined with the steam supply part 800. The fastening portion 3631 may be formed of a structure detachably combined with a protrusion protruding from the lower part of the steam housing 810.

[0306] Thus, even if a large amount of water is contained in the steam housing 810 , the steam housing 810 can be stably placed on the base cover 360 .

[0307] In addition, the steam housing 810 is disposed above the circulation duct 320 , so that the distance between the steam housing 810 and the inner housing 200 becomes shorter, thereby minimizing the condensation of the steam generated in the steam housing 810 before reaching the inner housing 200 .

[0308] Fig.15 It is a diagram showing the detailed structure of the steam supply unit.

[0309] Reference Fig.15 (a), the steam supply unit 800 may include: a steam housing 810 capable of receiving and storing water to generate steam; and a heater unit 840 accommodated in the steam housing 810 to generate steam by heating the water.

[0310] The steam housing 810 may have a housing shape with an upper portion opened, and may accommodate the heater unit 840 .

[0311] The steam supply unit 800 may further include a housing cover 820 coupled to the steam housing 810 to prevent the heater unit 840 from being exposed to the outside and to prevent the water from flowing out.

[0312] The housing cover 820 may be provided with: a water level sensor 850 for sensing the water level of the steam housing 810 ; and a steam sensor 860 for sensing the temperature inside the steam housing 810 or sensing whether steam is generated inside the steam housing 810 .

[0313] Reference Fig.15 (b), the steam housing 810 may include a housing body 811 providing a space for storing the water and accommodating the heater part 840 .

[0314] The housing body 811 has an open top, and various components can be easily installed inside the housing body 811 .

[0315] The housing body 811 may include a heater insertion hole 8111 through which one side is penetrated and through which the heater 840 can be inserted or led out.

[0316] The housing body 811 may include a recovery pipe 814 capable of discharging water contained inside to the outside.

[0317] The recovery pipe 814 can be kept in a closed state by a shielding cover 8141 so as to be opened only when the residual water inside the steam shell 810 is removed, and can include a shielding clip 8142, which keeps the shielding cover 8141 coupled to the recovery pipe 814 to prevent the shielding cover 8141 from being separated at will.

[0318] Therefore, when the steam housing 800 is repaired or the steam housing 800 is prevented from freezing, the water inside the steam housing 800 can be discharged through the recovery pipe 814 .

[0319] On the other hand, a heater fixing part 830 capable of supporting or fixing the heater part 840 may be provided inside the housing body 811. The heater fixing part 830 may include: a fixing clip 831 to fix the heater part 840; and a clip fastening member 833 to fix the supporting clip 831 to the housing body 811.

[0320] The fixing clip 831 may accommodate or surround at least a portion of the heater portion 840 .

[0321] On the other hand, the steam supply part 800 may have a water supply pipe 815 for receiving water. The water supply pipe 815 may communicate with the water supply tub 30 and receive water.

[0322] The water supply pipe 815 may be provided on the housing cover 820 or disposed on the upper portion of the steam housing 810. Thus, it is possible to prevent water from flowing back through the water supply pipe 815 again.

[0323] The steam supply unit 800 may include a steam pipe 813 for discharging steam generated by the heater unit 840 to the outside. The steam pipe 813 is also provided on the upper portion of the housing cover 820, thereby blocking water from being discharged toward the steam pipe 813. The steam pipe 813 may be communicated with the steam hole 233 of the inner housing 200.

[0324] The housing cover 820 may be provided with a water level sensor hole 854 in which the water level sensor may be provided.

[0325] The water level sensor 850 may include: one or more contact protrusions 852, which are inserted into the water level sensor hole 854, immersed in water and sense the water level; and a sensor body 851, which is combined with the water level sensor hole 854 or supported by the shell cover 820 in order to keep the contact protrusion 852 in a floating state inside the steam shell 810.

[0326] The sensor body 851 may be coupled to the housing cover 820 via a sensor fastening member 853 .

[0327] On the other hand, the housing cover 820 may have an insertion hole 864 for the steam sensor 860 to be installed. The steam sensor 860 may include: a sensing device 861 inserted into the insertion hole 864 to sense whether steam is generated inside the steam housing 810; a support platform 863 to fix the sensing device 861 to the housing cover 820; and a coupling member 862 to couple the support platform 863 to the housing cover 820.

[0328] The sensing device 861 may be a humidity sensor or a temperature sensor, and may sense whether steam is generated inside the steam housing 810 .

[0329] On the other hand, the housing cover 820 may include a cover hook 821 , and the cover hook 821 may extend forward and be coupled to the base cover 860 .

[0330] In addition, a fixing protrusion 822 may also be provided at the rear of the housing cover 820 , and the fixing protrusion 822 can fix the lower portion of the inner housing 200 or a separate steam exhaust portion 900 .

[0331] The heater unit 840 may be configured to be inserted into the heater insertion hole 8111 , accommodated in the steam housing 810 , receive power, and heat water.

[0332] The heater unit 840 may be a sheath heater or the like, and may be controlled so as to be repeatedly driven and stopped by the control unit 700 .

[0333] The heater part 840 may include a first heater 841 receiving a first power and heating water, and a second heater 842 receiving a power greater than the first power and heating water.

[0334] As a result, the second heater 842 can be configured to heat more water and generate more steam than the first heater 841.

[0335] The first heater 841 and the second heater 842 may be configured to separately consume the maximum heater power allowed by the heater part 840 in the laundry treating apparatus. That is, if the first heater 841 consumes a portion of the maximum heater power, the second heater 842 may consume the rest of the maximum heater power.

[0336] For example, when the maximum heater power normally allowed in the heater unit 840 is 1500 W, the first heater 841 may consume 600 W, and the second heater 842 may consume 880 W. 20 W may be allocated less in consideration of errors and the like.

[0337] Of course, the heater unit 840 may include more than three 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 may consume the maximum heater power separately.

[0338] The following description will be based on a case where the heater unit 340 includes the first heater 841 and the second heater 842 .

[0339] The first heater 841 and the second heater 842 may be formed as U-shaped metal pipes.

[0340] The heater portion 840 may include a heater seal 843 capable of fixing the first heater 841 and the second heater 842 and sealing the heater through hole 8111 ; and may include a terminal portion 844 for supplying current to the first heater 841 and the second heater 842 .

[0341] The terminal portion 844 may include a first terminal 844 a for supplying current to the first heater 841 , and a second terminal 844 b for supplying current to the second heater 842 .

[0342] The first heater 841 and the second heater 842 may be disposed at the same height. Therefore, the first heater 841 and the second heater 842 may generate steam by heating water at the same water level.

[0343] Thus, the control part 700 may adjust the amount of steam generated and the amount of power consumed by using the first heater 841 and the second heater 842 entirely or selectively.

[0344] Fig.16 1 is a diagram showing a laundry processing apparatus according to the present invention provided with a light emitting unit and a sensor unit.

[0345] The existing clothes treating device has the problem that clothes fall off the hanger during the clothes treating process.

[0346] As a result, the user cannot recognize the clothes that have fallen off the hanger during the clothes treatment process, and there is a problem that the clothes are damaged when the fallen clothes block the steam or hot air injection port.

[0347] In addition, the user can only recognize that the clothes have not been properly handled due to shedding after the clothing treatment process is completed, so the user cannot take proactive measures, resulting in a problem of reduced satisfaction with the use of the product.

[0348] In order to solve the above-mentioned problem, the present invention can provide a clothing processing device, which includes: a box body 100 having an opening at the front; an inner shell body 200, which is arranged inside the box body 100 and provides a space for accommodating clothes; a door 40, which is combined with the box body and opens and closes the opening; a hanger part 510, which is arranged at the upper part of the inner shell body 200 and places the clothes; a machine room 300, which is arranged at a position lower than the bottom surface of the inner shell body 200 and supplies at least one of hot air and steam to the inside of the inner shell body 200; a light-emitting part 600, which is arranged at one of the inner shell body 200, the door 40, and the machine room 300, and emits light to the inside of the inner shell body 200; and a sensor part 700, which is arranged at one of the inner shell body 200, the door, and the machine room, and senses that the clothes dropped from the hanger part 510 block at least a part of the light emitted from the light-emitting part 600.

[0349] In the laundry processing apparatus of the present invention, regardless of the locations of the light emitting unit 600 and the sensor unit 700, as long as the light emitted from the light emitting unit 600 reaches the sensor unit 700, the sensor unit 700 can sense the illumination change to determine whether the laundry has fallen.

[0350] The laundry treating apparatus may include a light emitting portion 600 that emits light toward the inside of the inner case 200 .

[0351] The light emitting unit 600 may emit any light as long as the sensor unit 700 can sense. For example, the wavelength of the light emitted from the light emitting unit 600 may be included in the range of ultraviolet rays, visible rays, and the like.

[0352] The wavelength of the light emitted from the light emitting unit 600 is most preferably in the visible light region rather than infrared light, ultraviolet light, etc. Infrared light can pass through objects, so it can pass through clothes even if they fall. On the other hand, visible light is an electromagnetic wave that can be recognized by the human eye and cannot pass through objects. In addition, if visible light is used, it is more suitable for clothing drop sensing using light blocking, which can protect the user's vision.

[0353] The light source of the light emitting unit 600 can be any component that emits light, such as an LED or a light bulb.

[0354] The laundry treating apparatus may include a sensor part 700 receiving the light emitted from the light emitting part 600 .

[0355] The sensor unit 700 may be an illuminance sensor that senses changes in illuminance of light emitted from the light emitting unit 600. Illuminance is a measure of brightness, and if a large amount of light is incident, the illuminance becomes high, and conversely, if a small amount of light is incident, the illuminance becomes low.

[0356] The sensor part 700 may sense at least one of whether the light emitted from the light emitting part 600 is received and the intensity of the light.

[0357] The sensor unit 700 may be disposed at a position where it can completely receive the light emitted from the light emitting unit 600. The specific disposition positions of the light emitting unit 600 and the sensor unit 700 will be described later.

[0358] The light emitting unit 600 and the sensor unit 700 may each include at least one.

[0359] When there are two or more light emitting units 600, the amount of light received by the sensor unit 700 increases, so whether the clothes have fallen can be more accurately understood.

[0360] In the laundry treating apparatus of the present invention, whether the laundry has fallen can be determined from the change in illumination of the light sensed in the sensor part 700 when the laundry has fallen during the laundry treating process.

[0361] For example, the sensor part 700 can be configured to be closer to the bottom surface of the inner shell 200 than the hanger part. When the clothes have not fallen, the sensor part 700 senses a first value. If the sensor part 700 senses a value smaller than the first value, the control part C can determine that the clothes have fallen.

[0362] Fig.17 1 is a diagram showing the spatial division of the inner casing of the clothes treating device of the present invention.

[0363] The inner housing 200 may include a first space area V1, a second space area V2, and a third space area V3 divided along a height.

[0364] The first spatial region V1 may be defined as a space between a first position a and a second position b.

[0365] The first position a may be a region corresponding to an upper surface of the inner case 200 or a lower surface of the hanger portion 510 .

[0366] The second position b may be located below the first position a by a first height.

[0367] The second position b may be located below the first position a by a length from the first position a to a fourth position d or 1 / 3 of the height of the inner housing 200 .

[0368] The height of the first spatial region V1 may be a first height h1.

[0369] The first height h1 may be greater than the length of the hanger in a height direction.

[0370] The first height h1 may be 1 / 3 of the length from the first position a to the fourth position d.

[0371] A hanger portion 510 may be provided in the first space region V1.

[0372] If clothes such as tops, baby clothes, skirts, etc. are placed on the hanger portion 510, clothes that are shorter and smaller than the first height can be placed in the first space area V1.

[0373] The second space region V2 may be defined as a space that is disposed below the first space region V1 and is located between the second position b and a third position c that is disposed below the second position b.

[0374] The second space region V2 may include a central portion of the inner shell 200 in a height direction.

[0375] If clothes of normal length, such as shirts and jackets, are placed on the hanger portion 510 , they can be allocated to the first space area V1 and the second space area V2 .

[0376] The third space region V3 may be defined as a space that is arranged below the second space region V2 and located between the third position c and the fourth position d.

[0377] If long clothes such as coats and pants are placed on the hanger portion 510 , they can be arranged in the first space area V1 , the second space area V2 , and the third space area V3 .

[0378] The dropped clothes may be placed in the lower part of the third space region V3 which is located lower than the second space region V2. Specifically, the dropped clothes may be placed in the lower part of the third space region V3.

[0379] The light emitting unit 600 and the sensor unit 700 may be provided in at least one of the first space region V1 , the second space region V2 , and the third space region V3 .

[0380] The sensor unit 700 may be provided at a position lower than the first position a.

[0381] The sensor unit 700 may be provided at a position higher than the fourth position d.

[0382] Thus, if the sensor unit 700 senses that the light emitting unit 600 is turned off while the light emitting unit 600 remains on, it can be determined that the clothing has fallen off.

[0383] Fig.18 FIG. 1 is a diagram showing an embodiment of the positions of a light emitting unit and a sensor unit of a clothes treating apparatus according to the present invention.

[0384] The laundry processing apparatus or the control unit C of the present invention can determine whether the laundry has fallen by sensing the increase in illumination through the sensor unit 700.

[0385] When the clothes are hung on the hanger part 510, the clothes block the light emitted from the light emitting part 600 from the sensor part 700. When the clothes fall, the light blocked by the clothes reaches the sensor part 700 due to the falling of the clothes. As a result, the clothes treating device or the control part C can determine whether the clothes fall by sensing the increase in illumination.

[0386] The light emitting unit 600 and the sensor unit 700 may each have a single one.

[0387] The light emitting unit 600 and the sensor unit 700 may be disposed in the same spatial region.

[0388] In a case where the light-emitting portion 600 and the sensor portion 700 are arranged at a position lower than a position (hereinafter referred to as a blocking position) on the inner surface of the inner shell 200 or the inner surface of the door 40 corresponding to a height equivalent to the lower end of the clothes when placed on the hanger portion 510, i.e., a blocking position e, the light emitted from the light-emitting portion 600 reaches the sensor portion 700 without being blocked from the beginning, and thus the sensor portion 700 cannot sense changes in illumination.

[0389] For example, when the light emitting unit 600 and the sensor unit 700 are arranged in the second spatial area V2 or the third spatial area V3, short and small clothes are only arranged in the first spatial area V1, so that even if the clothes fall, the sensor unit 700 cannot sense the increase in illumination.

[0390] Therefore, the light emitting unit 600 and the sensor unit 700 are preferably provided at a position at least above the blocking position e.

[0391] The blocking position e is set in at least one of the first space area V1, the second space area V2 and the third space area V3. In order to sense the falling of clothes even when the blocking position e is located in the first space area V1, the light emitting unit 600 and the sensor unit 700 are preferably set in the upper part of the first space area V1.

[0392] In addition, the light emitting unit 600 and the sensor unit 700 are preferably disposed at a lower position than the hanger unit 510. Thus, the sensor unit 700 can minimize the influence of the hanger unit 510 and sense the change in illumination of light by blocking the light emitted from the light emitting unit 600 with clothes.

[0393] Fig.19 FIG. 1 is a diagram showing an embodiment of the positions of a light emitting unit and a sensor unit of a clothes treating apparatus according to the present invention.

[0394] The sensor unit 700 and the light emitting unit 600 may be disposed in different spatial regions. As a result, the sensor unit 700 and the light emitting unit 600 may be disposed at different heights.

[0395] For example, the light emitting unit 600 may be disposed in the second space region V2, and the sensor unit 700 may be disposed in the first space region V1.

[0396] The light emitting unit 600 may be configured to radiate light toward the sensor unit 700 so that the sensor unit 700 can sense the light.

[0397] The light emitting unit 600 may emit light into a region where the sensor unit 700 can sense light. The sensor unit 700 may be disposed on the inner surface of the inner case 200 corresponding to the inner portion of the maximum tilt angle of the light irradiated from the light emitting unit 600 .

[0398] The light emitting portion 600 and the sensor portion 700 may be disposed on surfaces of the inner housing 200 that face each other.

[0399] The light emitting unit 600 may be arranged such that the light emitted from the light emitting unit 600 passes through the first space region V1. Thus, when short clothing is hung, the clothing may block the light emitted from the light emitting unit 600 to increase the illumination of the light sensed by the sensor unit 700.

[0400] In order to guide the light emitted from the light emitting unit 600 to the sensor unit 700 provided in another spatial region, a reflecting unit 400 or the like may be additionally provided.

[0401] Fig. 20 FIG. 1 is a diagram showing an embodiment of the positions of a light emitting unit and a sensor unit of a clothes treating apparatus according to the present invention.

[0402] The light emitting unit 600 and the sensor unit 700 may each include at least one.

[0403] The number of the light emitting units 600 and the number of the sensor units 700 may be different. When there are more than two light emitting units 600 , there may also be more than two sensor units 700 .

[0404] When there are two or more light emitting units 600 , there may be only one sensor unit 700 .

[0405] More than two light emitting units 600 may be disposed in different spatial regions. For example, the light emitting unit 600 may further include a first light emitting unit 610 disposed in the first spatial region V1 and a second light emitting unit 620 disposed in the second spatial region V2.

[0406] The first light emitting portion 610 and the second light emitting portion 620 may be disposed on one side of the inner housing 200 .

[0407] The first light emitting portion 610 and the second light emitting portion 620 may be disposed in parallel along a height direction of one side of the inner housing 200 .

[0408] The sensor unit 700 may be provided on a surface facing a surface on which the light emitting unit 600 is provided so as to face at least one of the first light emitting unit 610 and the second light emitting unit 620 .

[0409] The first light emitting unit 610 may be configured such that the light emitted from the first light emitting unit 610 reaches the sensor unit 700 through the first space region V1 and the second space region V2.

[0410] The second light emitting portion 620 may be configured such that light emitted from the second light emitting portion 620 reaches the sensor portion 700 through the second space region V2.

[0411] Therefore, the clothing processing device or control unit C can utilize the blocking of light emitted from the first light-emitting unit 610 to sense the falling of clothing set in the first space area V1, and can utilize the blocking of light emitted from the second light-emitting unit 620 to sense the falling of clothing set in the second space area V2.

[0412] Therefore, regardless of where the blocking position e is set, the sensor unit 700 can determine whether the clothes have fallen by sensing the change in the illumination of light.

[0413] In addition, the sensor part 700 may receive the light emitted from the light emitting part 600 at one time, and thus the laundry treating apparatus or the control part C may easily control the sensor part 700 at one time.

[0414] Fig.21 FIG. 1 is a diagram showing an embodiment of the positions of a light emitting unit and a sensor unit of a clothes treating apparatus according to the present invention.

[0415] A plurality of clothes may be placed on the hanger portion 510 provided in the first space region V1 from one side of the inner case 200 toward another side facing the one side. For example, the clothes may be placed along the width direction of the inner case 200.

[0416] In this case, the light emitting unit 600 and the sensor unit 700 may be respectively disposed on both sides of the inner housing 200. However, in the case of a plurality of clothes, even if a part of the clothes falls, the light emitted from the light emitting unit 600 is blocked by the clothes placed on at least one of the two sides of the fallen clothes, so that the sensor unit 700 may not be able to sense the change in illumination.

[0417] Therefore, the light emitting unit 600 and the sensor unit 700 may be provided on at least one of the rear surface of the inner case 200 and the door.

[0418] For example, the light emitting portion 600 may be disposed on the door so that the light emitted from the light emitting portion 600 is directed toward the inside of the inner housing 200 .

[0419] In this case, the sensor part 700 may be provided at the rear surface of the inner case 200 to face the light emitting part 600 .

[0420] Different from the above description, the light emitting unit 600 may be disposed on the rear surface of the inner housing 200, and the sensor unit 700 may be disposed on the door.

[0421] When the hanger portion 510 is disposed along the front-rear direction of the inner housing 200 , the sensor portion 700 and the light emitting portion 600 may be disposed on two side surfaces of the inner housing 200 .

[0422] As a result, the light emitting unit 600 and the sensor unit 700 may be arranged along the direction in which the hanger unit 510 is arranged on the inner surface of the inner shell 200 and the inner surface of the door 40 , or may be arranged at positions corresponding to the position where the hanger unit 510 is arranged.

[0423] The light emitting part 600 and the sensor part 700 may be disposed on the same line as a width direction of the hanger part 510 formed longer than a thickness direction of the hanger part 510 or a width direction of clothing hung on the hanger part 510 .

[0424] That is, the light emitting unit 600 and the sensor unit 700 may be disposed on both sides of the clothes placed on the hanger unit 510 .

[0425] For example, the light emitting unit 600 may emit light toward the side of the clothes hung on the hanger unit 510. Therefore, in the case where the clothes are not dropped, the clothes hung on the hanger unit 510 may block the light emitted from the light emitting unit 600.

[0426] The number of the light emitting unit 600 and the sensor unit 700 may be equal to the number of the hanger units 510. For example, if there are five hanger units 510, the number of the light emitting unit 600 and the sensor unit 700 may also be five.

[0427] The light emitting portion 600 may further include a first light emitting portion 610 , a second light emitting portion 620 , a third light emitting portion 630 , a fourth light emitting portion 640 and a fifth light emitting portion 650 .

[0428] The first light emitting unit 610 , the second light emitting unit 620 , the third light emitting unit 630 , the fourth light emitting unit 640 , and the fifth light emitting unit 650 may be arranged in a row to have the same intervals as the intervals between the hanger units 510 .

[0429] The sensor unit 700 may further include a first sensor unit 710 , a second sensor unit 720 , a third sensor unit 730 , a fourth sensor unit 740 , and a fifth sensor unit 750 .

[0430] The intervals between the first sensor part 710 , the second sensor part 620 , the third sensor part 730 , the fourth sensor part 740 , and the fifth sensor part 750 may be set to be the same as the intervals between the hanger parts 510 .

[0431] That is, the intervals between the first sensor unit 710, the second sensor unit 720, the third sensor unit 730, the fourth sensor unit 740, and the fifth sensor unit 750 can be arranged in a row at the same intervals as the intervals between the first light-emitting unit 610, the second light-emitting unit 620, the third light-emitting unit 630, the fourth light-emitting unit 640, and the fifth light-emitting unit 650.

[0432] The first sensor unit 710 , the second sensor unit 720 , the third sensor unit 730 , the fourth sensor unit 740 , and the fifth sensor unit 750 face the first light emitting unit 610 , the second light emitting unit 620 , the third light emitting unit 630 , the fourth light emitting unit 640 , and the fifth light emitting unit 650 , respectively.

[0433] If clothing located between the first light emitting portion 610 and the first sensor portion 710 falls, light emitted from the first light emitting portion 610 reaches the first sensor portion 710 due to the clothing, so that the first sensor portion 710 may sense an increase in illuminance of the light.

[0434] The light emitting unit 600 and the sensor unit 700 may be provided in one of the first space region V1 , the second space region V2 , and the third space region V3 .

[0435] When the blocking position e is located above the sensor unit 700, the clothes cannot block the light emitted from the light emitting unit 600, and thus it may be impossible to determine whether the clothes have fallen. Therefore, most preferably, the light emitting unit 600 and the sensor unit 700 are arranged in the first space region V1.

[0436] If at least one of the clothes hung on the hanger part 510 falls, the sensor part 700 senses the light emitted from the light emitting part 600 disposed on the same line as the clothes. As a result, the clothes treating apparatus or the control part C can sense that the illuminance of the light emitted from the light emitting part 600 increases.

[0437] Thus, when the clothes treating apparatus has a plurality of clothes, the sensor unit 700 senses an increase in the illumination of light, thereby determining not only whether clothes have fallen, but also what kind of clothes have fallen.

[0438] Fig. 22 FIG. 1 is a diagram showing another embodiment of the light emitting unit and the sensor unit of the laundry treating apparatus according to the present invention.

[0439] The laundry treating device or the control unit C may also determine whether the laundry has fallen by sensing the decrease in illumination through the sensor unit 700. When the laundry falls, the fallen laundry blocks the light emitted from the light emitting unit 600. Therefore, the light emitted from the light emitting unit 600 cannot reach the sensor unit 700, and thus the sensor unit 700 may sense the abnormal decrease in illumination.

[0440] That is, the sensor part 700 is arranged closer to the bottom surface of the inner housing 200 than the hanger part, and the sensor part 700 can set the light irradiated from the light emitting part 600 when the clothes are not dropped to the first value.

[0441] If the sensor unit 700 senses a value smaller than the first value, the control unit C may determine that the clothing has fallen.

[0442] The light emitting unit 600 and the sensor unit 700 may be arranged in the width direction or the front-rear direction based on the bottom surface of the inner housing 200 . Thus, part of the light emitted from the light emitting unit 600 may be blocked by the clothing dropped to the bottom surface of the inner housing 200 .

[0443] For example, the sensor part 700 can be configured on the rear surface of the inner shell 200, the light emitting part 600 can be configured in front of the sensor part 700, or the sensor part 700 can be configured on a side of the inner shell 200, and the light emitting part 600 can be configured on the side of the sensor part 700.

[0444] The sensor unit 700 and the light emitting unit 600 may be disposed on different surfaces of the inner housing 200 .

[0445] The sensor unit 700 may be provided on a surface facing a surface on which the light emitting unit 600 is provided.

[0446] At this time, the light emitted from the light emitting unit 600 should not reach the sensor unit 700 due to the fallen clothes, so preferably, the light emitting unit 600 and the sensor unit 700 are arranged to face each other.

[0447] For example, the light emitting unit 600 and the sensor unit 700 may face two side surfaces of the inner housing 200 respectively.

[0448] Alternatively, the light emitting unit 600 and the sensor unit 700 may be disposed to face at least one of the rear surface of the inner housing 200 and the door, respectively.

[0449] This shows an embodiment of the laundry processing device of the present invention in which the light emitting unit 600 is disposed on the door and the sensor unit 700 is disposed on the rear surface of the inner housing 200 .

[0450] The light emitting unit 600 may be disposed in the middle of the width direction of the door. Thus, even if the sensor unit 700 is disposed at any position, the unsensable area can be reduced, so that even if clothes fall from any position, the fallen clothes can be sensed and more light emitted from the light emitting unit 600 can be received.

[0451] The light emitting unit 600 and the sensor unit 700 may be arranged in the same spatial region. For example, the light emitting unit 600 and the sensor unit 700 may be arranged in the third spatial region V3. When the clothes fall, the clothes are located in the third spatial region V3, so the light emitting unit 600 and the sensor unit 700 are preferably arranged in the third spatial region V3.

[0452] The light emitting unit 600 and the sensor unit 700 may be arranged at a position lower than the hanger unit 510. The light emitting unit 600 and the sensor unit 700 may be arranged at a position lower than the lowest height e of the clothes. That is, the light emitting unit 600 and the sensor unit 700 may be arranged closer to the bottom surface of the inner housing 200 than the hanger unit 510. Thus, the clothes treating device or the control unit C may determine whether the clothes have fallen by minimizing the influence of the clothes hanging from the upper part.

[0453] Thus, the sensor unit 700 senses the reduction in light illumination caused by the fallen clothes, so when judging whether the clothes have fallen, it can judge whether the clothes have fallen only by using the reduction in light illumination blocked by the fallen clothes, without being affected by the length of the clothes, etc.

[0454] In addition, when the sensor unit 700 senses the decrease in illumination of light caused by the fallen clothes to determine whether the clothes have fallen, it is possible to more easily and accurately determine whether the clothes have fallen when there are multiple clothes.

[0455] In addition, the light emitting unit 600 and the sensor unit 700 can be used to a minimum, thereby reducing material costs and the like.

[0456] Fig.23 FIG. 1 is a diagram showing an embodiment of the positions of a light emitting unit and a sensor unit of a clothes treating apparatus according to the present invention.

[0457] The light emitting unit 600 and the sensor unit 700 may be disposed to face at least one of an upper portion and a lower portion of the inner housing 200 , respectively.

[0458] The light emitting unit 600 may be disposed on an upper surface of the inner housing 200 .

[0459] Alternatively, the light emitting portion 600 may be disposed at a lower portion of the hanger portion 510 .

[0460] The sensor part 700 may be disposed on the bottom surface of the inner housing 200 so as to be shielded by clothes when the clothes fall.

[0461] Alternatively, the sensor unit 700 may be disposed inside the machine room or the inflow body, thereby facilitating maintenance and power supply.

[0462] Different from the above description, the light emitting unit 600 may be disposed at the lower portion of the inner housing 200, and the sensor unit 700 may be disposed at the upper portion of the inner housing 200. In this case, the light emitting unit 600 may be disposed in the machine room or in the inflow body.

[0463] The light emitting unit 600 and the sensor unit 700 may be disposed facing each other on a straight line.

[0464] Specifically, if the clothes fall, the sensor unit 700 is blocked to block the light emitted from the light emitting unit 600. As a result, the clothes treating apparatus or the control unit C can determine whether the clothes fall by sensing the decrease in illumination of the light by the sensor unit 700.

[0465] The light emitting unit 600 and the sensor unit 700 may have at least one. In particular, the more sensor units 700, the better. In most cases, when clothes fall, they fall to the periphery of the area suspended by gravity. Therefore, when there are a plurality of sensor units 700, the sensor unit 700 can more accurately determine whether the clothes have fallen.

[0466] For example, three sensor parts 700 may be provided on the bottom surface of the inner housing 200. The sensor parts 700 may include a first sensor part 710, a second sensor part 720, and a third sensor part 730.

[0467] The first sensor unit 710 , the second sensor unit 720 , and the third sensor unit 730 may be arranged in a row.

[0468] At least one of the first sensor portion 710 , the second sensor portion 720 , and the third sensor portion 730 may face the light emitting portion 600 .

[0469] When clothes fall, the clothes fall onto the upper part of at least one of the first sensor part 710, the second sensor part 720 and the third sensor part 730, thereby blocking at least one of the first sensor part 710, the second sensor part 720 and the third sensor part 730.

[0470] Thus, by sensing a decrease in the illumination of light through at least one of the first sensor unit 710, the second sensor unit 720, and the third sensor unit 730, the laundry treating apparatus or the control unit C can determine whether the laundry has fallen.

[0471] In addition, whether the clothes have fallen can be judged only by using the reduction in illumination of the light blocked by the fallen clothes, without being affected by the length, quantity, etc. of the clothes.

[0472] Fig.24 FIG. 1 is a diagram showing an embodiment of a reflecting portion of a clothes treating apparatus according to the present invention.

[0473] On the other hand, in the case where the light emitting unit 600 and the sensor unit 700 are arranged facing each other, the light emitted from the light emitting unit 600 travels straight and reaches the sensor unit 700. Therefore, in the case where clothing falls to an area other than the area where the light emitted from the light emitting unit 600 travels straight toward the sensor unit 700, the sensor unit 700 may not sense the change in illumination because the light is not blocked by the clothing.

[0474] The laundry treating apparatus may include a first drop region S1 disposed between the light emitting portion 600 and the sensor portion 700 , and an unsensible region X defined as a region other than the first drop region S1 .

[0475] If clothes fall into the first falling area S1, the fallen clothes block the light emitted from the light emitting portion 600, so that the sensor portion 700 can sense the reduction in illumination. However, if clothes fall into the unsensible area, the fallen clothes cannot block the light emitted from the light emitting portion 600, so that the sensor portion 700 cannot sense the reduction in illumination.

[0476] However, even in the case where a small portion of the dropped laundry falls on the first drop region S1, the light emitted from the light emitting part 600 is blocked by a portion of the laundry, and thus the sensor part 700 can sense a decrease in illumination.

[0477] In order to determine whether the laundry has fallen regardless of where the laundry has fallen by minimizing the unsensable area X, the laundry treating apparatus may further include a reflecting portion 400 .

[0478] The reflective portion 400 may be at least one reflective plate that reflects the light irradiated from the light emitting portion 600 .

[0479] The reflective plate may be provided on a surface of the inner surface of the inner case 200 that is different from a surface on which the light emitting portion 600 and the sensor portion 700 are provided.

[0480] For example, the reflective portion 400 may include: a first reflective plate 410 disposed on a side surface of the inner housing 200; and a second reflective plate 420 disposed on a surface facing a surface on which the first reflective plate 410 is disposed.

[0481] The first reflection plate 410 and the second reflection plate 420 may be disposed at the center of the width direction of one surface of the inner housing 200. Thus, the unsensible area X may be reduced by further ensuring the second drop area S2 and the third drop area S3.

[0482] For example, the first reflecting plate 410 and the second reflecting plate 420 may face each other.

[0483] The first reflective plate 410 and the second reflective plate 420 may be disposed at the center of one surface of the inner housing 200 in the width direction.

[0484] The laundry processing apparatus may further include: a second drop region S2 formed by light irradiated from the light emitting portion 600 being reflected by the first reflecting plate 410 and reaching the sensor portion 700; and a third drop region S3 formed by light irradiated from the light emitting portion 600 being reflected by the second reflecting plate 420 and reaching the sensor portion 700. Compared with a case where the reflecting portion 400 is not provided, in the case where the reflecting portion 400 is provided, the area of ​​the non-sensible region X is reduced. In the case where laundry falls and a part of the laundry falls to one of the first drop region S1, the second drop region S2, and the third drop region S3, the light emitted from the light emitting portion 600 is blocked by the fallen laundry, so that the sensor portion 700 can sense that the illumination of the light emitting portion 600 is reduced.

[0485] Therefore, the laundry treating apparatus minimizes the unsensable area X, thereby making it possible to determine whether the laundry has fallen even if the laundry has fallen to any area of ​​the bottom surface of the inner case 200 .

[0486] Fig.25 1 is a diagram showing a filter unit of a clothes treating apparatus according to the present invention.

[0487] In order to prevent dust from flowing into the circulation duct 320 , the laundry treating apparatus 1 may include a filter portion 380 located at an upper portion of the machine room 300 .

[0488] The filter unit 380 may be installed at the inflow body 361 to filter dust flowing into the inflow body 361 .

[0489] The filter unit 380 may include a main body filter 386 installed on the upper portion of the inflow body 361 of the base cover 360 to shield a portion of the upper surface of the inflow body 361. The main body filter 386 may block large dust and may be formed of a mesh material through which light can pass.

[0490] The filter unit 380 may further include a main body cover 385 for accommodating the main body filter 386. The main body cover 385 may be disposed on the upper portion of the inflow body. The main body cover 385 may shield one side of the upper portion of the first inflow port 3621 and the third inflow port 3622. The portion of the main body cover 385 shielding the top surface of the first inflow port 3621 and the third inflow port 3622 may have perforations. In the case where the main body filter 386 is not installed, the main body cover 385 may prevent dust from flowing into the interior of the circulation duct 320 by blocking large dust.

[0491] In order to fix the main body cover 385 and the main body filter 386, the filter part 380 may further include a filter fixing part 384. The filter fixing part 384 may be disposed on the upper part of the base cover 360. The peripheral surface of the main body cover 385 may be combined with the filter fixing part 384 and may be assembled and detached from the filter fixing part 384.

[0492] The laundry processing device may further include a filter cover 382 located on the upper portion of the main body cover 385. The filter cover 382 may be wider than the main body cover 385. The filter cover 382 may cover one side of the main body filter 386. The lower surface of the filter cover 382 may be formed by a lattice-shaped injection molding. The filter cover 382 may be separated from the bottom surface of the inner housing 200 so that the air inside the inner housing 200 flows into the circulation duct 320.

[0493] A blocking cover 381 may be provided on the upper portion of the filter cover 382. The blocking cover 381 may completely shield the top surface of the opening of the machine room 300.

[0494] Fig.26 FIG. 1 is a diagram showing an embodiment of the positions of a light emitting unit and a sensor unit of a clothes treating apparatus according to the present invention.

[0495] The light emitting unit 600 and the sensor unit 700 may be disposed at any position as long as the sensor unit 700 cannot sense the light emitted from the light emitting unit 600 due to the dropped clothes.

[0496] Therefore, the light emitting unit 600 and the sensor unit 700 are preferably disposed below the hanger unit 510. The area below the hanger unit 510 includes the second space region V2, the third space region V3, and the machine room 300 in the inner housing 200.

[0497] Therefore, one of the light emitting unit 600 and the sensor unit 700 may be disposed inside the machine room, and the other of the light emitting unit 600 and the sensor unit 700 may be disposed in the inner housing 200 or the door 40 .

[0498] The light emitting unit 600 may be disposed in the lower portion of the inner housing 200, particularly inside the machine room 300. This may facilitate power supply and maintenance, and when determining whether clothing has fallen, the influence of clothing falling inside the inner housing 200 may be minimized.

[0499] The light emitting unit 600 may be disposed toward the sensor unit 700 so that the sensor unit 700 receives the light emitted from the light emitting unit 600. In this case, the filter cover 382 may not be provided.

[0500] When clothes fall, the clothes exist in the third space area V3, and the sensor part 700 senses that the light is blocked by the fallen clothes, so the sensor part 700 can be set at the lower part of the inner shell 200, that is, the third space area V3.

[0501] In order for the sensor unit 700 to sense light emitted from the light emitting unit 600 disposed inside the machine room 300 , the light emitting unit 600 and the sensor unit 700 are preferably disposed in a width direction or a front-rear direction with respect to the bottom surface of the inner housing 200 .

[0502] That is, a portion of the path of the light emitted from the light emitting unit 600 should pass in parallel with the bottom surface of the inner housing 300 in the width direction or the front-rear direction.

[0503] Therefore, the sensor part 700 can be configured on the rear surface of the inner shell 200, and the light emitting part 600 can be configured in front of the sensor part 700, or the sensor part 700 can be configured on a side surface of the inner shell 200, and the light emitting part 600 can be configured on the side surface of the sensor part 700.

[0504] When clothes fall, there is a high possibility that the clothes fall to the rear of the inner shell 200 , so the light emitted from the light emitting unit 600 preferably crosses the inner shell 200 along the front-rear direction of the inner shell 200 .

[0505] For example, the light emitted from the light emitting unit 600 may be directed toward the rear of the inner housing 200. Therefore, the sensor unit 700 is also preferably disposed on the rear surface of the inner housing 200 to face the inside of the inner housing 200.

[0506] In the case where the laundry falls, the fallen laundry blocks the light emitted from the light emitting part 600. Therefore, the sensor part 700 senses the abnormal illumination reduction, whereby the laundry treating apparatus or the control part C can determine that the laundry falls.

[0507] The light emitting unit 600 may be provided at a lower portion than the main body filter 386 in front of or behind the main body cover 385 .

[0508] The light emitting unit 600 may also be provided in the machine room at a lower position than the main body filter 386. Thus, the light emitting unit 600 can be prevented from being degraded due to dust or the like filtered by the main body filter 386, and can be prevented from being exposed to the eyes of the user.

[0509] The light emitting unit 600 and the sensor unit 700 may be provided via the body filter 386. Thus, the light emitting unit 600 is provided such that light emitted from the light emitting unit 600 passes through the body filter 386 and is sensed by the sensor unit 700.

[0510] The light emitting unit 600 may be provided on one side of the inflow body 361. The light emitting unit 600 may be provided on the front side or the rear side of the inflow body 361 to emit light to the upper part of the inflow body 361. That is, the light emitting unit 600 may be provided to emit light to the upper part of the first inflow port 3621 or the third inflow port 3622. A shielding member for shielding the second inflow port 3623 may also be combined with the second inflow port 3623 of the inflow body 361. Therefore, light cannot be emitted to the upper part of the second inflow port 3623, and thus it is preferably provided on the front side or the rear side of the inflow body 361 instead of the side.

[0511] The light emitting portion 600 may further include an illumination setting portion for setting a light source. The illumination setting portion may penetrate the front surface or the rear surface of the inflow body.

[0512] The light-emitting unit 600 is arranged at the lower part of the main filter 386, so that the clothing processing device or the control unit C can not only use the sensor unit 700 to sense the illumination change of the light emitted from the light-emitting unit 600 to determine whether the clothing has fallen, but also determine whether the main filter 386 is loaded and unloaded or the contamination degree of the main filter 386.

[0513] On the other hand, the machine room 300 may be disposed to the left of the laundry processing apparatus. The center of the machine room 300 in the width direction may be different from the center of the laundry processing apparatus in the width direction. The center of the laundry processing apparatus in the width direction may be disposed on the right side of the machine room 300.

[0514] Therefore, the light emitting portion 600 may be disposed on the same line as the center of the width direction of the laundry treating apparatus, rather than the center of the width direction of the machine room 300 .

[0515] The sensor part 700 may be disposed at the center of the width direction of the rear surface of the inner housing 200. Thus, the sensor part 700 and the light emitting part 600 may be disposed on a straight line with the center of the width direction of the inner housing 200.

[0516] That is, the sensor part 700 can be set at the center of the width direction of the rear surface of the inner shell, the inflow body 361 can be configured to one side on the bottom surface of the inner shell, and the light-emitting part 600 can be configured inside the inflow body 361 at a position corresponding to the sensor part 700.

[0517] Different from the above description, the positions of the light emitting unit 600 and the sensor unit 700 may be interchanged with each other.

[0518] The light emitting unit 600 and the sensor unit 700 may be provided in one. Thus, the laundry treating apparatus can save material cost and manufacturing cost, and can effectively sense whether the laundry has fallen by using one sensor unit 700.

[0519] On the other hand, when the light emitting portion 600 is disposed at the lower portion of the main body filter 386, due to the angle of light emitted from the light emitting portion 600 and the step between the main body cover 385 and the inner shell 200, the light cannot reach the sensor portion 700 disposed on the rear surface of the inner shell 200.

[0520] In order for the sensor part 700 to sense the change in the illumination of the light emitted from the light emitting part 600 , the light emitted from the light emitting part 600 should be guided to the lower portion of the inner case 200 and finally reach the sensor part 700 .

[0521] Therefore, when the light-emitting unit 600 is disposed inside the mechanical room 300, in order to guide the light emitted from the light-emitting unit 600 to the sensor unit 700 and ensure sensing of the required illumination, a reflecting unit 400 may be further included. The reflecting unit 400 is configured to be arranged at a position higher than the light-emitting unit 600 to guide the light emitted from the light-emitting unit 600 to the sensor unit 700.

[0522] The reflective portion 400 may be formed at a position, an angle, and an amount that enable the sensor portion 700 to sense the light emitted from the light emitting portion 600 by reflection.

[0523] The reflective unit 400 may be configured to reflect the light emitted from the light emitting unit 600 and guide the light to the sensor unit 700 regardless of where the light emitting unit 600 and the sensor unit 700 are disposed.

[0524] The reflective portion 400 may be disposed at an upper position than the light emitting portion 600 and may be arranged on a straight line with the light emitting portion 600. The light emitted from the light emitting portion 600 may directly reach the reflective portion 400.

[0525] The reflective portion 400 may be disposed between the light emitting portion 600 and the sensor portion 700 .

[0526] The reflecting part 400 may be disposed at a position higher than the main body filter 386 and disposed between the main body filter 386 and the light emitting part 600. The reflecting part 400 may be disposed on one surface of the main body cover 385. Thus, the light emitted from the light emitting part 600 is guided to the reflecting part 400, and the contamination degree of a local area of ​​the main body filter 386 may be sensed.

[0527] The reflecting portion 400 may be disposed between the filter cover 382 and the main body filter 386. The reflecting portion 400 may be disposed on the lower surface of the filter cover 382. In order to overcome the step between the main body cover 385 and the bottom surface of the inner housing 200 and guide the light emitted from the light emitting portion 600 to the sensor portion 700 located on the rear surface of the inner housing 200 by the reflecting portion 400, the reflecting portion 400 is preferably disposed on the lower surface of the filter cover 382.

[0528] When the reflector 400 is disposed at the lower portion of the filter cover 382, ​​the filter cover 382 may further include a reflector 400 installation portion for installing the reflector 400 at the lower surface of the filter cover 382. The detailed structure of the filter cover 382 will be described later.

[0529] Thus, the light emitted from the light emitting part 600 is guided to the sensor part 700 through the spaced-apart space between the filter cover 382 and the bottom surface of the inner case 200, so that the sensor part 700 can sense the reduction in illumination caused by the dropped laundry.

[0530] Fig. 27 It is a diagram showing the structure of the first reflection plate.

[0531] The reflective portion 400 may further include a first reflective plate 410 disposed on the same line as the light emitting portion 600 along a height direction.

[0532] The first reflective plate 410 may be disposed on a lower surface of the filter cover 382 .

[0533] The first reflection plate 410 may be disposed at the center of the filter cover 382 in the width direction.

[0534] The light emitting unit 600 , the sensor unit 700 , and the first reflective plate 410 may be arranged on a straight line. The first reflective plate 410 may be provided with a first reflective surface 411 that directly reflects the light emitted from the light emitting unit 600 to the sensor unit 700 .

[0535] The first reflective surface 411 may be disposed toward the rear of the laundry treating device.

[0536] The first reflection plate 410 may be provided with a hook 414 that can be coupled to the filter cover 382 .

[0537] The laundry treating apparatus may further include a first path R1 for guiding the light emitted from the light emitting portion 600 to the sensor portion 700 through the first reflective surface 411 .

[0538] The first path R1 may pass through a lower portion of the inner case 200. The first path R1 may be close to a bottom surface of the inner case 200.

[0539] In the case where the laundry falls, the fallen laundry blocks the light passing through the first path R1. Therefore, the sensor part 700 senses the abnormal illumination reduction, so that the laundry treating apparatus or the control part C can determine that the laundry falls.

[0540] Fig.28 FIG. 1 is a diagram showing an embodiment of a reflecting portion of a clothes treating apparatus according to the present invention.

[0541] Fig.28 (a) shows an exploded perspective view of the filter unit 380. Fig.28 (b) is a diagram showing a cross section of the machine room cut along the transverse direction.

[0542] There may be a situation where the light emitted from the light emitting unit 600 cannot be sufficiently transmitted to the sensor unit 700 using only the first reflective plate 410 .

[0543] Therefore, if Fig.28 As shown in (a), the reflective portion 400 may further include a second reflective plate 420 and a third reflective plate 430 symmetrically arranged on both sides of the first reflective plate 410 in order to fully transmit the light emitted from the light emitting portion 600 to the sensor portion 700 .

[0544] The second reflecting plate 420 and the third reflecting plate 430 may be disposed on a lower surface of the filter cover 382 close to two side surfaces of the filter cover 382 .

[0545] At this time, the first reflective plate 410 may further include: a second reflective surface 412 for reflecting the light reflected from the light emitting portion 600 to the second reflective plate 420 ; and a third reflective surface 413 for reflecting the light reflected from the light emitting portion 600 to the third reflective plate 430 .

[0546] In addition, the second reflection plate 420 may include a fourth reflection surface 421 that reflects the light reflected from the second reflection surface 412 toward the sensor unit 700. The third reflection plate 430 may include a fifth reflection surface 431 that reflects the light reflected from the third reflection surface 413. Thus, the light reflected from the fourth reflection surface 421 and the fifth reflection surface 431 may be sensed by the sensor unit 700.

[0547] That is, the first reflection plate 410 may reflect the light emitted from the light emitting portion 600 to the second reflection plate 420 and the third reflection plate 430. The light reflected by the second reflection plate 420 and the third reflection plate 430 may be sensed by the sensor portion 700.

[0548] The laundry treating apparatus may further include a second path R2 for guiding the light emitted from the light emitting portion 600 to the sensor portion 700 through the second reflecting surface 412 of the first reflecting plate 410 and the fourth reflecting surface 421 of the second reflecting plate 420 .

[0549] The laundry treating apparatus may further include a third path R3 for guiding the light emitted from the light emitting portion 600 to the sensor portion 700 through the third reflection surface 413 of the first reflection plate 410 and the fifth reflection surface 431 of the third reflection plate 430 .

[0550] In the case where the laundry falls, the fallen laundry blocks the light passing through the second path and the third path. Therefore, the sensor part senses the abnormal illumination reduction, so that the laundry treating device or the control part C can determine that the laundry falls.

[0551] In addition, the light emitted from the light emitting portion 600 is guided to the first path R1 , the second path R2 , and the third path R3 , and the contamination degree of a local area of ​​the body filter 386 may be sensed.

[0552] Fig.29 FIG. 1 is a diagram showing an embodiment of a reflecting portion of a clothes treating apparatus according to the present invention.

[0553] like Fig.28 As shown, when the reflecting part 400 includes the first reflecting plate 410, the second reflecting plate 420, and the third reflecting plate 430, when the clothing falls and blocks at least one of the first path R1, the second path R2, and the third path R3, the sensor part 700 can sense about 0 to 66% of the light emitted from the light emitting part 600. However, when the main body filter 386 is installed and the clothing does not fall, the sensor part 700 can sense about 60 to 70% of the light emitted from the light emitting part 600. Therefore, when the clothing falls and when the clothing does not fall, the amount of light sensed by the sensor part 700 overlaps, and if the light less than about 66% is sensed, it cannot be sensed, and there is a possibility that the accuracy of judging the clothing falling is reduced.

[0554] Therefore, in order to eliminate the overlapping range, in the clothing processing device, the light emitting unit 600 is arranged at the lower part of the main filter 386, and the sensor unit 700 is arranged at the inner shell 200 or the door 40 and is closer to the filter unit 380 than the hanger unit 510, the reflecting unit 400 may only include the second reflecting plate 420 and the third reflecting plate 430 in addition to the first reflecting plate 410.

[0555] The second reflecting plate 420 and the third reflecting plate 430 are provided so that the light emitted from the light emitting portion 600 can pass through the body filter 386 and go through the second path R2 and the third path R3.

[0556] If the clothes fall to the bottom surface of the inner case 200 , the clothes may block at least one of the second path R2 and the third path R3 .

[0557] Thus, the control unit C can determine whether the clothes have fallen by the change in the illumination of the light emitted from the light emitting unit 600 by the sensor unit 700.

[0558] Specifically, when the main body filter 386 is installed and the clothes are not dropped, the sensor unit 700 may sense about 60-70% of the light emitted from the light emitting unit 600. At this time, when the clothes are dropped and block at least one of the second path R2 and the third path R3, the sensor unit 700 may sense about 0-50%.

[0559] Therefore, the overlapping range of the amount of light sensed by the sensor unit 700 disappears when the clothes fall and when the clothes do not fall, so that the control unit C can accurately determine whether the clothes fall and whether the main filter 386 is loaded and unloaded only by configuring the second reflector 420 and the third reflector 430 on both sides of the filter cover 382.

[0560] Fig.30 2 is a diagram showing a laundry drop area of ​​the laundry treating apparatus of the present invention.

[0561] On the other hand, when the light emitting unit 600 is disposed in the machine room or the lower part of the main body filter, the light emitted by the light emitting unit 600 is emitted to the rear of the inner housing 200, and therefore, an area blocked by the filter cover 382 and cannot be sensed by the sensor unit 700 may also occur, that is, an unsensable area X. If clothes fall into the unsensable area X, the light emitted from the light emitting unit 600 cannot be blocked by the fallen clothes, and therefore the sensor unit 700 cannot sense the reduction in illumination.

[0562] Therefore, a reflective portion 400 may be further included, wherein the reflective portion 400 is configured to disperse the light emitted from the light emitting portion 600 in at least two directions so that the sensor portion 700 senses that the clothes dropped to the bottom surface block the light emitted from the light emitting portion 600 .

[0563] like Fig.30 As shown in (a), there is a higher possibility that the clothes fall to the rear of the inner shell 200 or the area of ​​the fallen clothes is wider than the unsensable area X, and thus only fall to a part of the unsensable area X. Therefore, when the light-emitting unit 600 is arranged in the machine room 300 or the lower part of the main body filter 366, the sensor unit 700 can also sense the illumination change of the light emitted from the light-emitting unit 600.

[0564] Just, if Fig.30 As shown in (b), when a very small piece of clothing such as a towel falls or drops in front of the inner shell 200, the area of ​​the fallen clothing is narrower than the unsensible area X, so it can fall into the unsensible area X.

[0565] Therefore, if Fig.30 As shown in (c), in order to minimize the non-sensible area X of the sensor part 700, the reflective part 400 can be arranged between the sensor part 700 and the light emitting part 600 on both sides of the sensor part 700 and the light emitting part 600.

[0566] The second reflective plate 420 and the third reflective plate 430 may be disposed close to both sides of the filter cover 382. In addition, in order to minimize the unsensable area X of the sensor part 700, the second reflective plate 420 and the third reflective plate 430 may be disposed close to the rear surface of the filter cover 382.

[0567] Therefore, the second reflecting plate 420 and the third reflecting plate 430 are arranged as close as possible to both sides and the rear surface of the filter cover 382, ​​so that the unsensible area X can be minimized.

[0568] The reflective portion 400 may be disposed closer to the light emitting portion 600 than the sensor portion 700 .

[0569] In the reflection part 400 , the sensor part 700 and the light emitting part 600 may be arranged along the front-rear direction with the bottom surface as a reference, and the reflection part 400 may be arranged along the width direction with the bottom surface as a reference.

[0570] The plurality of reflection parts 400 may be arranged symmetrically with the sensor part 700 .

[0571] The plurality of reflective units 400 may be symmetrically arranged with respect to the sensor unit 700 and the light emitting unit 600 .

[0572] Fig.31 It is a figure which shows the structure of the filter cover of the clothes processing apparatus of this invention.

[0573] Fig.31 (a) shows a bottom perspective view of the filter cover 382, Fig.31 (b) is a diagram showing the lower surface of the filter cover 382 on which the reflecting portion 400 is provided.

[0574] The filter cover 382 may include a first reflective plate installation portion 3821 a , and the first reflective plate installation portion 3821 a may be used to install the first reflective plate 410 on a lower surface of the filter cover 382 .

[0575] The filter cover 382 may further include: a second reflector installation portion 3821b, on which the second reflector 420 may be installed at the lower surface of the filter cover 382; and a third reflector installation portion 3821c, on which the third reflector 430 may be installed. The second reflector installation portion 3821b and the third reflector installation portion 3821c may be symmetrically installed on both sides of the first reflector installation portion 3821a.

[0576] The filter cover 382 may include a connecting rod installation portion 3822 , and the connecting rod installation portion 3822 may install a connecting rod 383 detachably coupled to the filter fixing portion 384 on a lower surface of the filter cover 382 .

[0577] The filter cover 382 may include a hook 3823 , and the hook 3823 is supported by the filter fixing portion 384 at a lower surface of the filter cover 382 .

[0578] The filter cover 382 may include a fragrance sheet installation portion 3824 , and the fragrance sheet installation portion 3824 may be configured to install a fragrance sheet for deodorizing air at a lower portion of the filter cover 382 .

[0579] The present invention has been shown and described with reference to specific embodiments, but it is obvious to those skilled in the art that the present invention may be variously modified and changed without departing from the scope of the technical idea of ​​the present invention provided by the following claims.
