Description

Garment processing equipment

[0001] The present invention relates to a garment treatment device and a control method thereof. More specifically, the present invention relates to a garment treatment device capable of performing refreshing processes, such as sterilizing, removing wrinkles, deodorizing, and drying, by supplying steam and hot air to garments.

[0002] A dryer is a clothing treatment device that supplies hot air to clothing stored in a drum, rotates the drum to evenly expose the hot air to the clothing, and performs a drying process to remove moisture from the clothing.

[0003] Recently, a clothing treatment device has appeared that can simultaneously perform a drying cycle with a dryer and a washing machine that removes foreign substances from clothing using water and detergent.

[0004] Conventional garment treatment devices that perform a drying process may include a circulating dryer that condenses and reheats air laden with moisture evaporated from garments by hot air and then circulates it back to the drum. Such circulating dryers have the advantage of not changing the external humidity or temperature even when performing the drying process.

[0005] These circulating dryers include a heater pump system that includes multiple heat exchangers, such as evaporators and condensers, because the air discharged from the drum must be cooled and reheated.

[0006] While these evaporators and condensers can exchange heat with the air passing through them, lint from clothing inevitably accumulates in the air. Specifically, the evaporator is designed to exchange heat with the air discharged from the drum first, so lint and other foreign substances discharged from the drum accumulate there the most. This buildup of foreign substances in the evaporator not only impedes heat exchange between the evaporator and the air, reducing drying performance, but can also hinder or block the airflow itself.

[0007] Recently, a garment treatment device has emerged that features a washing unit that washes accumulated foreign substances in the evaporator using an external water source or condensate. These devices discharge the external water source and condensate through a nozzle positioned above the evaporator, thereby washing foreign substances from the evaporator and the duct in which it is installed.

[0008] In particular, a clothing treatment device has been developed that includes a nozzle arranged to extend in the width direction of the evaporator and to clean the entire area of ​​the evaporator. (See Korean Patent Publication No. 10-2021-0139899 and Korean Patent Publication No. 10-2016-0001189)

[0009] Figure 1 illustrates a structure of a conventional clothing treatment device that washes an evaporator.

[0010] The nozzle (N) of a conventional clothing treatment device had the advantage of being able to extend in the width direction of the evaporator (H) and spray water over the entire area of ​​the evaporator (H).

[0011] However, the nozzle (N) of the conventional clothing treatment device is designed to spray water while moving in the width direction of the evaporator (H) in the same direction as it was supplied, so that when the supplied water is of low pressure, water cannot be properly supplied to the end of the nozzle, and when the supplied water is of high pressure, the supplied water becomes turbulent in the upstream area (I) adjacent to one end of the nozzle, and there is a problem that the water cannot be properly sprayed.

[0012] In addition, when the amount of water supplied is so large that it can move from one end of the nozzle to the other end during the process of water being sprayed, there was a problem in that a stagnant area (II) was generated between one end and the other end of the nozzle due to a collision between the water entering the nozzle and the water remaining after moving to the other end of the nozzle and not being discharged, and the amount of water sprayed in that section was reduced.

[0013] Therefore, there was a problem in which foreign substances were not washed away and remained in the areas of the evaporator and duct facing the upper and lower parts of the nozzle where water was not sprayed smoothly.

[0014] This residual foreign matter could combine with newly introduced foreign matter and grow to block the entire evaporator area, and could also block the duct itself, causing problems by blocking the movement of air.

[0015] Additionally, there was a problem in which the remaining foreign substances decayed due to moisture, causing the clothes inside the drum to become contaminated during the drying process.

[0016] Furthermore, the conventional clothing treatment device had a problem in that the storage space inside the nozzle (N) where water is not sprayed was connected to an arbitrary section of the spray path where water is sprayed, so that the water pressure of the sprayed water dropped and the flow rate sprayed throughout the spray path was not maintained consistently.

[0017] The present invention aims to solve the problem of providing a clothes treatment device with a nozzle that normally discharges water over the entire section extending in the width direction of the evaporator.

[0018] The present invention aims to provide a clothing treatment device in which water can be normally delivered and sprayed to the end of a nozzle or spray path even when the supplied water is at low pressure.

[0019] The present invention aims to provide a clothing treatment device capable of supplying water uniformly throughout the entire nozzle section even when the supplied water is at high pressure.

[0020] The present invention aims to provide a clothing treatment device in which water is normally discharged without stagnation areas throughout the entire nozzle section even when a large amount of water is supplied.

[0021] In order to solve the above-described problem, the present invention provides a clothes treatment device including a cabinet having an opening at the front, a drum rotatably provided inside the cabinet to store clothes fed into the opening, a circulation duct forming a path for guiding air discharged from the drum to the drum, a fan mounted on the circulation duct to move the air, a heat exchanger disposed inside the circulation duct to cool or heat the air, and a water supply washing unit mounted on the circulation duct to receive water and wash the circulation duct or the heat exchanger.

[0022] The above water supply washing unit may include a water supply valve coupled to the cabinet to receive water from an external water source, a supply pipe coupled to the water supply valve to deliver the water, and a supply nozzle coupled to an end of the supply pipe to discharge the water into the circulation duct.

[0023] The above supply nozzle may include a nozzle case mounted on the circulation duct, a connection pipe provided at one end of the nozzle case and connected to the supply pipe, a spray path for discharging water supplied from the connection pipe inside the nozzle case into the circulation duct, and a nozzle path section including an additional space in which water passing through the spray path is collected at least temporarily.

[0024] The above additional space may be provided to receive water that has moved from the connecting pipe to the end of the injection path.

[0025] The above additional space may be provided so that it is connected only to the end or downstream of the injection path and is blocked from connecting to the area between one end and the end of the injection path.

[0026] The above supply nozzle may further include a baffle disposed inside the nozzle case to block water flowing into the nozzle case from flowing into the additional space before passing through the entire injection path.

[0027] The above-mentioned bulkhead can extend from the lower surface to the upper surface of the nozzle case to completely partition the injection path and the additional space.

[0028] The above additional space can be arranged in the forward and backward direction of the injection path inside the nozzle case.

[0029] The above bulkhead may be placed between the injection path and the additional space.

[0030] The length of the above bulkhead may be formed to be shorter than the length of the injection path and the length of the additional space.

[0031] The length of the above additional space can be formed to be equal to or shorter than the length of the above injection path.

[0032] The cross-sectional area of ​​the above additional space may be formed to be equal to or smaller than the cross-sectional area of ​​the above injection path.

[0033] The above nozzle flow path may further include an inlet flow path that is provided to connect the connecting pipe and the injection flow path and transmit water.

[0034] The above-mentioned intake path can be formed so that an area with a constant cross-sectional area is longer than an area with a variable cross-sectional area.

[0035] The length of the above-mentioned intake passage can be formed to be equal to or longer than the length of the above-mentioned injection passage.

[0036] The length of the above-mentioned intake path can be formed longer than the length of the above-mentioned additional space.

[0037] The above-mentioned intake path, the above-mentioned injection path, and the above-mentioned additional space can be arranged to overlap in the front-back direction inside the nozzle case.

[0038] The above injection path can be arranged between the above intake path and the above additional space.

[0039] The above supply nozzle may further include a baffle disposed inside the nozzle case to block water from flowing into the injection path before it passes through the entire intake path.

[0040] The above injection path may include a protruding surface protruding from the nozzle case toward the heat exchanger, and a plurality of injection holes that penetrate the protruding surface and discharge the water.

[0041] The washing unit of the clothing treatment device of the present invention may include a nozzle mounted on the circulation duct to discharge the supplied water.

[0042] The above additional space may be provided to communicate with the end of the injection path so that water passing through the entire injection path is collected.

[0043] The present invention has the effect of normally discharging water over the entire section extending in the width direction of the evaporator.

[0044] The present invention has the effect of enabling water to be normally delivered and sprayed to the end of a nozzle or spray path even when the water being supplied is at low pressure.

[0045] The present invention has the effect of supplying water uniformly throughout the entire nozzle section even when the supplied water is at high pressure.

[0046] The present invention has the effect of normally discharging water without stagnation areas throughout the entire nozzle section even when the amount of water supplied is large.

[0077] Hereinafter, embodiments disclosed in this specification will be described in detail with reference to the attached drawings. In this specification, identical or similar components are given identical or similar reference numerals even in different embodiments, and the description thereof is replaced with the first description. The singular expression used in this specification includes plural expressions unless the context clearly indicates otherwise. In addition, when describing the embodiments disclosed in this specification, if a detailed description of a related known technology is judged to obscure the gist of the embodiments disclosed in this specification, the detailed description thereof will be omitted. In addition, it should be noted that the attached drawings are only intended to facilitate easy understanding of the embodiments disclosed in this specification, and the technical ideas disclosed in this specification should not be construed as being limited by the attached drawings.

[0078] Figure 2 illustrates the appearance of the clothing treatment device of the present invention.

[0079] The clothing treatment device of the present invention may be equipped as a dryer for drying clothes, or may be equipped as a combined laundry dryer that can dry clothes while washing them.

[0080] Hereinafter, the description will be made based on the garment treatment device of the present invention being equipped with a dryer, but it is not excluded that the garment treatment device of the present invention is equipped with a washing and drying device.

[0081] A garment treatment device according to one embodiment of the present invention may include a cabinet (100) forming an exterior.

[0082] The cabinet (100) may include a front panel (110) forming the front surface of the garment treatment device, an upper panel (150) forming the upper surface, and a side panel (140) forming the side surface. The side panel (140) may include a left panel (141) forming the left surface. The front panel (110) may be provided with an opening (111) provided to communicate with the interior of the cabinet (100), and a door (130) rotatably coupled to the cabinet (100) to open and close the opening (111).

[0083] An operation panel (117) may be installed on the front panel (110). The operation panel (117) may be provided with an input unit (118) for receiving a control command from a user, and a display unit (119) for outputting information such as control commands that can be selected by the user. The control commands may include a drying course or drying option that can perform a series of drying operations. A control box (see FIG. 10) that controls internal components to perform the control commands input through the input unit (118) may be installed inside the cabinet (100). The control box may be connected to components inside the garment treatment device and control the corresponding components to perform the input commands.

[0084] The above input unit (118) may be provided to include a power supply request unit that requests power supply to the garment treatment device, a course input unit that allows the user to select a desired course from among a plurality of courses, and an execution request unit that requests the start of a course selected by the user.

[0085] The above display unit (119) may be provided to include at least one of a display panel capable of outputting text and shapes, and a speaker capable of outputting voice signals and sounds.

[0086] Meanwhile, the garment treatment device of the present invention may include a water storage tank (120) that is provided to separately store moisture generated during the drying process of the garment. The water storage tank (120) may include a handle that is provided so as to be withdrawable to the outside from one side of the front panel (110). The water storage tank (120) may be provided to collect condensate generated during the drying process. Thus, a user may withdraw the water storage tank (120) from the cabinet (100), remove the condensate, and then re-install it in the cabinet (100). Thus, the garment treatment device of the present invention may be placed even in a location where a drain or the like is not installed.

[0087] Meanwhile, the water storage tank (120) may be placed on the upper part of the door (130). This allows the user to bend his / her back relatively less when pulling out the water storage tank (120) from the front panel (110), thereby increasing user convenience.

[0088] Figure 3 is a simplified illustration of the interior of the clothing treatment device of the present invention.

[0089] The clothing treatment device of the present invention may include a drum (200) accommodated inside the cabinet (100) to accommodate clothing, a driving unit that rotates the drum (200), a heat exchange unit (900) that supplies hot air to the drum (200), and a base (800) that is provided with a circulation duct (820).

[0090] The above circulation duct (820) is provided to communicate with the drum (200). Air discharged from the drum (200) can be supplied to the circulation duct (820). In addition, air discharged from the circulation duct (820) can be supplied back to the drum (200).

[0091] The above driving unit may include a motor unit (500) that provides power to rotate the drum (200).

[0092] The garment treatment device of the present invention may be installed in a base (800) where the motor unit (500) is positioned lower than the drum (200), and the drum (200) may be configured to rotate by the power of the motor unit (500) due to a structure such as a belt and pulley.

[0093] In addition, the garment treatment device of the present invention may be provided such that the driving unit is directly connected to the drum (200) so as to rotate the drum (200), as illustrated. For example, the driving unit may be provided as a DD (Direct Drive unit) type. Accordingly, the driving unit can control the rotational direction or rotational speed of the drum (200) by directly rotating the drum (200) without requiring components such as belts and pulleys.

[0094] Hereinafter, the description will be made based on the case where the driving unit of the garment treatment device of the present invention is arranged as a DD type, but this does not exclude the case where the driving unit of the garment treatment device of the present invention is arranged as a belt / pulley type.

[0095] The above motor unit (500) can rotate at a high RPM. For example, it can rotate at a much higher RPM than the RPM at which clothes inside the drum (200) can rotate while attached to the inner wall of the drum (200).

[0096] However, there is a problem that the drying efficiency decreases because the clothes inside the drum (200) are continuously attached to the inner wall of the drum (200) and rotate, and the part attached to the inner wall of the drum is not exposed to hot air.

[0097] If the rotor (520) is rotated at a low RPM so that the clothes inside the drum (200) roll or are stirred without being attached to the inner wall of the drum (200), a problem may occur in which the output or torque that the driving unit can generate is not properly utilized.

[0098] Accordingly, the driving unit of the garment treatment device of the present invention may further include a reducer (600) that can increase torque while utilizing the maximum output of the motor unit (500) by reducing the RPM.

[0099] The above-described reducer (600) may include a gearbox including a sun gear coupled to a motor unit (500) therein, a planetary gear that rotates while meshing with the sun gear, a ring gear arranged on an outer surface of the planetary gear, and a carrier that rotates according to the revolution of the planetary gear. The above-described reducer (600) may include a rotation shaft that is connected to the gearbox and coupled to the rear surface of the drum (200).

[0100] The drum (200) may be provided in a cylindrical shape to accommodate clothing. The drum (200) may omit the through hole provided along the circumference.

[0101] The above drum (200) may be provided in an integral cylindrical shape, but may also be manufactured in a form in which a drum body (210) including a circumferential surface and a drum rear surface (220) forming a rear surface are combined.

[0102] An inlet (211) for clothes to enter and exit may be provided at the front of the drum body (210). A driving unit for rotating the drum may be connected to the rear of the drum back surface (220). The drum body (210) and the drum back surface (220) may be joined by a fastening member such as a bolt, but are not limited thereto. If the drum body (210) and the drum back surface (220) are joined so that they can rotate together, they may be joined using various methods.

[0103] The drum body (210) may be equipped with a lifter (213) that pulls the clothes contained therein upward so that the clothes can be mixed as the drum rotates. As the drum (200) rotates, the clothes contained therein can be repeatedly raised and lowered by the lifter (213). The clothes contained within the drum (200) can be evenly exposed to hot air as they repeatedly rise and fall. Therefore, the drying efficiency is increased and the drying time is shortened.

[0104] A reinforcing bead (212) may be formed on the circumference of the drum body (210). The reinforcing bead (212) may be provided to be recessed or protruding from the inside / outside along the circumference of the drum (200). A plurality of such reinforcing beads may be provided, and may be provided spaced apart from each other.

[0105] The rigidity of the drum body (210) can be increased by the reinforcing beads (212). Therefore, even if a large amount of clothing is accommodated in the drum body (210) or a sudden rotational force is transmitted through the driving unit, the drum body (210) can be prevented from twisting.

[0106] When the clothing treatment device of the present invention is equipped with a DD type washing machine, the driving unit is fixedly coupled to a tub that accommodates the drum (200) and stores water, and the drum (200) can be coupled to the driving unit and supported by the tub.

[0107] However, when the garment treatment device of the present invention is equipped with a DD type dryer, the tub accommodating the drum (200) may be omitted. Accordingly, the garment treatment device of the present invention may further include a support member (400) provided to fix or support the drum (200), the motor member (500), and the reducer (600) within the cabinet (100).

[0108] The support member (400) may include a front plate (410) disposed in front of the drum (200) and a rear plate (420) disposed in the rear of the drum (200). The front plate (410) and the rear plate (420) may be provided in a plate shape and may be disposed to face the front and rear of the drum (200). The distance between the front plate (410) and the rear plate (420) may be set to be equal to the length of the drum (200) or longer than the length of the drum (200). The front plate (410) and the rear plate (420) may be fixed to and supported by the bottom surface or base (800) of the cabinet (100).

[0109] The front plate (410) may be placed between the front panel forming the front surface of the cabinet and the drum (200). In addition, the front plate (410) may be provided with an input communication hole (412) communicating with the input port (211). Since the front plate (410) is provided with the input communication hole (412), clothes can be put into or taken out of the drum (200) while supporting the front surface of the drum (200).

[0110] The front plate (410) may include a duct connection portion (416) provided on the lower side of the injection communication hole (412). The duct connection portion (416) may form the lower surface of the front plate (410).

[0111] The front plate (410) may include a duct communication hole (417) penetrating the duct connection portion (416). The duct communication hole (417) is provided in a hollow shape and can guide air discharged through the drum inlet (211) to the lower side of the drum (200). In addition, the air discharged through the drum (211) can be guided to a circulation duct (820) located at the lower side of the drum (200).

[0112] A filter unit (not shown) may be installed in the above duct communication hole (417) to filter out lint or large foreign substances generated from clothing. The filter unit filters the air discharged from the drum (200), thereby preventing foreign substances from accumulating inside the clothing treatment device and preventing the accumulation of foreign substances from interfering with air circulation.

[0113] Since the above-mentioned inlet (211) is positioned at the front, it is preferable that the driving unit be installed on the rear plate (420) rather than the front plate (410). The driving unit may be provided to be mounted and supported on the rear plate (420). Accordingly, the driving unit can rotate the drum (200) while its position is stably fixed through the rear plate (420).

[0114] At least one of the front plate (410) and the rear plate (420) can rotatably support the drum (200). At least one of the front plate (410) and the rear plate (420) can rotatably accommodate the front or rear end of the drum (200).

[0115] For example, the front of the drum (200) may be rotatably supported on the front plate (410), and the rear of the drum (200) may be spaced apart from the rear plate (420) but connected to the motor unit (500) mounted on the rear plate (420) and indirectly supported on the rear plate (420). As a result, the area where the drum (200) comes into contact with or rubs against the support unit (400) can be minimized, and unnecessary noise or vibration can be prevented from occurring.

[0116] Of course, the drum (200) may be provided to be rotatably supported on both the front plate (410) and the rear plate (420).

[0117] At least one support wheel (415) for supporting the front of the drum (200) may be provided at the lower portion of the front plate (410). The support wheel (415) may be rotatably provided on the rear surface of the front plate (410). The support wheel (415) may be rotated while in contact with the lower portion of the drum (200).

[0118] When the drum (200) is rotated by the driving unit, the drum (200) may be supported by a drum rotation shaft (6341) connected to the rear. When clothing is accommodated inside the drum (200), the load imposed on the drum rotation shaft (6341) by the clothing may increase. Therefore, the drum rotation shaft (6341) is at risk of bending due to the load.

[0119] When the support wheel (415) supports the front lower part of the drum (200), the load applied to the drum rotation shaft (6341) can be reduced. Accordingly, the drum rotation shaft (6341) can be prevented from bending and noise generated by vibration can be prevented.

[0120] The above support wheels (415) are provided at positions symmetrical to each other with respect to the center of rotation of the drum (200) to support the load of the drum (200). It is preferable that the support wheels (415) are provided at the lower left and right sides of the drum (200) to support the drum (200). However, this is not limited to this, and a greater number of support wheels (415) may be provided depending on the operating environment of the drum (200).

[0121] The above circulation duct (820) can form a path that circulates the air inside the drum (200) and then returns it to the inside of the drum (200).

[0122] The above circulation duct (820) may include an inlet duct (821) into which air discharged from the drum (200) is introduced, an exhaust duct (823) that supplies air to the drum (200), and a moving duct (822) that connects the inlet duct (821) and the exhaust duct (823).

[0123] When air is discharged from the front of the drum (200), the moving duct (822) may be located on the front side of the circulation duct (820). And the discharge duct (823) may be located on the rear side of the circulation duct (820).

[0124] A duct cover (830) is attached to the upper side of the above-mentioned circulation duct (820), so as to partially shield the open upper surface of the circulation duct (820). The duct cover (830) can prevent air from leaking out of the circulation duct (820). In other words, the duct cover (830) can form one side of a flow path through which air circulates.

[0125] In addition, the heat exchange unit (900) provided in the base (800) may include an evaporator (910) provided inside the circulation duct (820) to cool air and a condenser (920) provided inside the circulation duct (820) to heat air cooled in the evaporator (910).

[0126] The above evaporator (910) dehumidifies air discharged from the drum (200), and the condenser (920) can heat the dehumidified air. The heated air can be supplied back to the drum (200) to dry clothes contained in the drum (200).

[0127] The above evaporator (910) and the above condenser (920) may be provided as a heat exchanger through which refrigerant flows.

[0128] The refrigerant moving along the above evaporator (910) and condenser (920) may be provided to exchange heat with the air discharged from the drum (200).

[0129] The heat exchange unit (900) may include a circulation fan (950) installed in the circulation duct (820) to generate air flow inside the circulation duct (820). In addition, the heat exchange unit (900) may further include a circulation fan motor (951) that rotates the circulation fan (950). The circulation fan (950) may rotate by receiving rotational power from the circulation fan motor (951). When the circulation fan (950) operates, air dehumidified in the evaporator (910) and heated in the condenser (920) may move to the rear of the drum (200).

[0130] The circulation fan (950) may be installed in any one of the inlet duct (821), the moving duct (822), and the exhaust duct (823). Since the circulation fan (950) is designed to rotate, noise may be generated when the circulation fan (950) operates. Therefore, it is preferable that the circulation fan (950) be placed at the rear of the circulation duct (820).

[0131] The above circulation fan (950) may be installed in the air blower duct (8231). In addition, the circulation fan motor (951) may be positioned at the rear of the air blower duct (8231). When the circulation fan (950) rotates by the circulation fan motor (951), air inside the circulation duct (820) may be discharged to the outside of the circulation duct (820) through the air blower duct (8231).

[0132] Since it is preferable that the inlet (211) of the drum (200) be positioned at a relatively high position so that the user can easily take out clothes located inside the drum (200), it is preferable that the circulation duct (820) and the heat exchange unit (900) be positioned at the bottom of the drum (200).

[0133] A rear plate (420) may be provided at the rear of the drum (200) to guide air discharged from the circulation duct (820) to the drum (200). The rear plate (420) may be provided to be spaced apart from the rear surface (220) of the drum. The circulation duct (820) may receive air inside the drum (200) through the front plate (410) and supply air to the drum (200) through the rear plate (420). The air discharged from the circulation duct (820) may be guided to the drum (200) by passing through the rear plate (420).

[0134] The above base (800) may further include a connector (850) that guides the air discharged from the circulation duct (820) to the rear plate (420). The connector (850) may guide the discharged air to be evenly distributed throughout the entire rear plate (420).

[0135] The above drum (200) may include a drum body (210) having a cylindrical shape and configured to accommodate clothing, and a drum back surface (220) coupled to the rear of the drum body (210) to form the back surface of the drum.

[0136] The drum back surface (220) may be provided to shield the rear of the drum body (210) and provide a coupling surface directly coupled to the driving unit. That is, the drum back surface (220) may be provided to be connected to the driving unit and receive rotational power to rotate the entire drum (200). As a result, an input port (211) for inserting clothes may be formed at the front of the drum body (210) and the rear may be shielded by the drum back surface (220).

[0137] The drum back surface (220) may be provided with a bushing (300) that connects the driving unit and the drum back surface (220). The bushing (300) may be provided on the drum back surface (220) to form a center of rotation of the drum (200). The bushing (300) may be provided as an integral part with the drum back surface (220), but may be provided with a material that has greater rigidity or durability than the drum back surface (220) in order to be firmly connected to the rotation shaft that transmits power. The bushing (300) may be mounted and connected to the drum back surface (220) so as to be coaxial with the center of rotation of the drum back surface (220).

[0138] The drum back surface (220) may include a peripheral portion (221) coupled to the outer surface of the drum body (210) and a mounting plate (222) provided on the inner side of the peripheral portion (221) and capable of being coupled to the driving unit. The bushing portion (300) may be seated and coupled to the mounting plate (222). The rotating shaft that rotates the drum is coupled to the mounting plate (222) through the bushing portion (300), thereby providing an effect of more secure coupling. In addition, deformation of the drum back surface (220) may be prevented.

[0139] The drum back surface (220) may include a suction hole (224) formed through a penetration between the peripheral portion (221) and the mounting plate (222) and connecting the front and rear surfaces of the drum back surface (220). Hot air supplied through the circulation duct (820) may be introduced into the drum body (210) through the suction hole (224). The suction hole (224) may be provided as a plurality of holes formed through the drum back surface (220) or may be provided as a mesh-shaped net.

[0140] A driving unit that rotates the drum (200) may be positioned at the rear of the rear plate (420). The driving unit may include a motor unit (500) that generates rotational power and a reducer (600) that reduces the rotational power of the motor unit (500) and transmits it to the drum (200).

[0141] A motor unit (500) may be placed at the rear of the rear plate (420). In addition, the motor unit (500) may be coupled to the rear of the rear plate (420) via the reducer (600).

[0142] The above-described reducer (600) is fixed to the rear surface of the rear plate (420), and the motor unit (500) can be coupled to the rear surface of the reducer (600). That is, the rear plate (420) can provide a support surface on which the reducer (600) or the motor unit (500) is supported. However, the present invention is not limited thereto, and the motor unit (500) can also be coupled to the rear plate (420).

[0143] Figure 4 is an exploded perspective view showing the internal components of the garment treatment device separated from each other.

[0144] The front plate (410) may include a front panel (411) forming a front surface, and an input communication hole (412) formed to penetrate the front panel (411) and communicate with the drum (200). The front plate (410) may be provided on the back surface of the front panel (411), and a front gasket (413) may be provided to surround the radially outer side of the input communication hole (412) and accommodate a portion of the drum body (210).

[0145] The front gasket (413) can rotatably support the drum body (210) and can be provided so as to be in contact with the outer or inner surface of the inlet (211). The front gasket (413) can prevent hot air inside the drum (200) from leaking between the drum body (210) and the front plate (410). The front gasket (413) can be provided with a plastic resin series or an elastic body, and a separate sealing member can be additionally coupled to the front gasket (413) to prevent clothes or hot air from escaping from the drum body (210) to the front plate (410).

[0146] Meanwhile, the front plate (410) may include a duct communication hole (417) formed by penetrating the inner surface of the injection communication hole (412). In addition, the front plate (410) may include a duct connection part (416) that extends downward from the duct communication hole (417) to form a flow path connecting the drum body (210) and the circulation duct (820).

[0147] The above duct connection part (416) can be communicated with the drum body (210) through the duct communication hole (417), and the air discharged from the drum body (210) can be introduced into the duct connection part (416) through the duct communication hole (417) and guided to the circulation duct (820). Since the air discharged from the drum body (210) is guided to the circulation duct (820) by the duct connection part (416), there is an effect of preventing the air inside the drum from leaking out.

[0148] A filter member (not shown) that filters foreign substances or lint from the air discharged from the drum (200) and prevents foreign substances from entering the circulation duct (820) may be installed in the above duct connection part (416).

[0149] The front plate (410) is rotatably installed on the back surface of the front panel (411), and a support wheel (415) that supports the lower portion of the drum (200) can be installed. The support wheel (415) supports the front of the drum (200), which has the effect of preventing the rotation shaft connected to the drum from bending.

[0150] The front plate (410) may be provided with a water tank support hole (414) that penetrates the front panel (411) and allows a water tank (120, see FIG. 1) for storing condensate generated during the drying process to be withdrawn or supported. If the water tank support hole (414) is provided on the upper side, the user does not have to bend over when withdrawing the water tank, which increases the convenience of the user.

[0151] The drum back surface (220) may include a peripheral portion (221) connected to the drum body (210), a suction hole (224) formed to penetrate the drum back surface (220) from the inside of the peripheral portion (221), and a mounting plate (222) provided at the center of rotation of the drum back surface (220) and coupled to a rotational shaft. Air may be introduced to the rear of the drum through the suction hole (224).

[0152] The drum back surface (220) may further include a reinforcing rib (225) extending from the peripheral portion (221) toward the center of rotation. The reinforcing rib (225) may extend to avoid the suction hole (224). The reinforcing rib (225) has the effect of preventing the rigidity of the drum back surface (220) from being reduced due to the suction hole (224). The reinforcing rib (225) may be provided to extend radially from the outer peripheral surface of the mounting plate (222) toward the inner peripheral surface of the peripheral portion (221).

[0153] In addition, the drum back surface (220) may further include a circumferential rib (227) that extends in the circumferential direction of the drum back surface (220) to connect the reinforcing ribs (225) to each other. The suction hole (224) may be arranged between each reinforcing rib (225), the circumferential rib (227), and the peripheral portion (221). The reinforcing rib (225) and the circumferential rib (227) have the effect of preventing the drum back surface (220) from being deformed even when rotational force is transmitted from the motor unit (500).

[0154] The above inlet duct (821) may be provided to communicate with the duct communication hole (417) of the front plate (410) and the flow path installed inside the front plate (410). The moving duct (822) may be provided to extend from the end of the inlet duct (821) toward the rear of the drum (200), and the exhaust duct (823) may be provided at the end of the moving duct (822) to guide the air to the drum (200).

[0155] The above-mentioned blower duct (8231) may be positioned downstream of the above-mentioned exhaust duct (823), and the blower duct (8231) may provide a space in which a circulation fan is installed. When the circulation fan operates, air drawn into the inlet duct (821) may be discharged to the upper portion of the blower duct (8231).

[0156] Meanwhile, a heat exchange unit (900) capable of cooling and heating air circulating within the drum (200) may be installed in the base (800). The heat exchange unit (900) may further include a compressor (930) connected to the evaporator and the condenser to supply compressed refrigerant. The compressor (930) may be provided so as not to directly exchange heat with the circulating air, and thus may be located outside the circulation duct (820).

[0157] Additionally, the heat exchange unit may include a circulation fan motor (951) that is supported at the rear of the blower duct (8231) and rotates the circulation fan.

[0158] The above exhaust duct (823) may further include a blower duct (8231) for exhausting air to the outside of the circulation duct (820). The blower duct (8231) may be provided at the rear side of the exhaust duct (823). The air exhausted through the blower duct (8231) may move to the drum (200).

[0159] The above connector (850) can be installed in the air duct (8231). That is, the connector (850) can guide the air discharged from the air duct (8231) to the rear plate (420). The hot air supplied to the rear plate (420) can be introduced into the interior of the drum (200) through the drum rear surface (220).

[0160] The above circulation fan motor (951) can be coupled to the rear of the blower duct (8231).

[0161] Meanwhile, a clothing treatment device according to one embodiment of the present invention may further include a connector (850) coupled to the circulation duct (820) to guide hot air discharged from the circulation duct (820) to the rear of the drum (200) or the rear plate (420).

[0162] The connector (850) may be positioned above the exhaust duct (823) to guide the heated hot air passing through the condenser (920) upward from the exhaust duct (823). In addition, the connector (850) may be coupled to an opening provided on the upper side of the blower duct (8231).

[0163] The connector (850) may be provided to form a flow path therein. The connector (850) may be provided to evenly guide the air flow generated by the circulation fan to the rear plate (420). That is, the connector (850) may be provided so that the area of ​​the flow path increases as it gets farther away from the blower duct (8231).

[0164] The rear plate (420) may be coupled to the base (800) or supported by the base (800) and positioned at the rear of the drum (200). The rear plate (420) may include a rear panel (421) positioned to face the front plate (410), a duct portion (423) provided to be recessed in the rear panel (421) to form a flow path for air and to guide air discharged from the circulation duct (820) to the drum.

[0165] The above rear plate (420) may include a mounting portion (425) to which the driving portion is coupled or supported. The mounting portion (425) may be provided to penetrate the rear panel (421) and may be arranged on the inner circumference of the duct portion (423). The mounting portion (425) may be provided to be spaced radially inward from the inner circumference of the duct portion (423).

[0166] Here, the driving unit may refer to a combination of the reducer (600) and the motor unit (500) as described above. And the driving unit may refer to only the motor unit (500). In other words, a component that generates power and transmits rotational power to the drum may be referred to as the driving unit.

[0167] The above driving unit can be mounted on the mounting unit (425). The mounting unit (425) can support the load of the driving unit. The driving unit can be connected to the drum (200) while being supported by the mounting unit (425).

[0168] The above duct portion (423) may be provided to accommodate a portion of the drum back surface (220). The duct portion (423) may form a path through which air moves together with the drum back surface (220).

[0169] The driving unit may be installed in the mounting portion (425) so as to prevent interference with the duct portion (423). That is, the driving unit may be positioned radially inwardly from the inner circumferential surface of the duct portion (423). The driving unit may be installed in the mounting portion (425), but may be installed so that the rear side is exposed to the outside so as to be cooled by external air.

[0170] The above driving unit may include a motor unit (500) that provides power to rotate the drum (200). The motor unit (500) may include a stator (510) that generates a rotating magnetic field and a rotor (520) that is provided to rotate by the stator (510).

[0171] The rotor (520) may be provided as an outer rotor type that accommodates the stator (510) and is configured to rotate around the circumference of the stator (510). At this time, a drive shaft may be coupled to the rotor (520) and may be directly connected to the drum (200) by penetrating the stator (510) and the mounting portion (425). In this case, the rotor (520) may directly transmit power to rotate the drum (200).

[0172] The above rotor (520) can be coupled to the drive shaft through the washer portion (540). The washer portion (540) can perform the function of connecting the drive shaft and the rotor (520). Since the contact area between the rotor (520) and the drive shaft can be increased by the washer portion (540), there is an effect of more effectively transmitting the rotation of the rotor (520).

[0173] The above reducer (600) may be provided to connect the motor unit (500) and the drum (200). The reducer (600) may convert the power of the motor unit (500) to rotate the drum (200). The reducer (600) may be arranged between the motor unit (500) and the drum (200) to receive the power of the motor unit (500), convert it, and transmit it to the drum (200). The reducer (600) may be provided to convert the RPM of the rotor into a small RPM, increase the torque value, and transmit it to the drum (200).

[0174] Specifically, the reducer (600) may be coupled with a drive shaft that is coupled with the rotor (520) and rotates together with the rotor (520). The reducer (600) includes a gear combination that is internally engaged with the drive shaft and rotates to change the rpm of the drive shaft while increasing the torque, and the gear combination may be connected to a drum rotation shaft that is coupled to the drum (200) and rotates the drum. Therefore, when the drive shaft (530) rotates, the drum rotation shaft rotates at a slower rpm than the drive shaft, but can rotate with a greater torque.

[0175] The performance of this reducer (600) may depend on whether the drive shaft and the drum rotation shaft can maintain coaxiality. That is, if the drive shaft and the drum rotation shaft are misaligned, there is a risk that the components constituting the gear assembly inside the reducer (600) may become loose or disengaged from at least one of the drive shaft and the drum rotation shaft. Accordingly, the power of the drive shaft may not be properly transmitted to the drum rotation shaft, or the drive shaft may rotate.

[0176] In addition, if the drive shaft and the drum rotation shaft are misaligned even temporarily, the gears inside the reducer (600) may misalign with each other and collide, causing unnecessary vibration or noise.

[0177] In addition, if the angle of misalignment between the drive shaft and the drum rotation shaft becomes severe, even temporarily, there is a risk that the reducer (600) may completely move out of its original position or be damaged.

[0178] To prevent this, it is preferable that garment treatment devices equipped with a reducer fix the reducer (600) and the motor unit (500) to a support that maintains its original state without deformation even when an external force is applied.

[0179] For example, in the case of a washing machine, a method can be applied in which the tub accommodating the drum is first fixed to a cabinet, and then the motor unit and the reducer are secondarily fixed to a bearing housing made of a rigid body that is injection-molded and built into the inside of the tub. Accordingly, even if significant vibration occurs in the tub, the reducer and the driving unit can tilt or vibrate together with the bearing housing or the fixed steel plate. As a result, the effect of the reducer and the driving unit themselves always remaining coupled can be achieved, and the driving shaft and the rotating shaft can be maintained in a coaxial state.

[0180] However, since the clothes treatment device of the present invention is equipped with a dryer, the configuration of a tub fixed inside the cabinet is omitted. In addition, since the back panel of the cabinet is equipped with a relatively thin plate, even if the stator (510) is fixed, the back panel can easily vibrate or bend due to the repulsive force when the rotor (520) rotates. If the back panel vibrates or bends even temporarily, a problem may occur in which the centers of rotation of the reducer (600) and the motor unit (500), which are arranged in combination with the drum (200), are misaligned with each other.

[0181] In addition, since the back panel is made of a thin steel plate, it may be difficult to support both the reducer (600) and the motor unit (500). For example, when the reducer (600) and the motor unit (500) are coupled to the back panel in parallel, a rotational moment may be generated due to the overall length and self-weight of the reducer (600) and the motor unit (500), causing the reducer (600) to sag downward. As a result, the drum rotation shaft itself coupled to the drum may become misaligned with the reducer (600), and may not be able to maintain coaxiality with the drive shaft.

[0182] Meanwhile, it may be considered that the stator (510) is coupled to the rear plate (420) to support the motor unit (500). When a large amount of clothing is accommodated inside the drum (200) or eccentricity occurs, the drum rotation axis may be twisted along the arrangement of the clothing each time the drum (200) rotates. At this time, since the stator (510) is separated from the drum (200) and fixed to the rear plate (420), the drum rotation axis may vibrate at a different width or tilt at a different angle from the stator (510). Therefore, the coaxiality of the drum rotation axis and the drive shaft may not be maintained.

[0183] From another perspective, the drum (200) can be installed in a position that is supported by the front plate (410) and the rear plate (420) and can be fixed to a certain level. Accordingly, the position of the drum rotation axis coupled to the drum (200) can also be fixed to a certain level. Accordingly, even if vibration occurs in the drum (200), the vibration can be buffered by at least one of the front plate (410) and the rear plate (420).

[0184] However, if the vibration generated from the drum (200) is transmitted to the motor unit (500), even if the reducer (600) and the motor unit (500) are fixed to the rear plate (420), the vibration amplitude of the motor unit (500) and the rear plate (420) may be greater than the vibration amplitude of the drum rotation shaft. In this case, a problem may occur in which the drive shaft and the drum rotation shaft cannot maintain coaxiality.

[0185] To solve this problem, the garment treatment device of the present invention can fix the motor unit (500) by coupling it to the reducer (600). In other words, the reducer (600) itself can serve as a reference point for the entire driving unit. That is, the reducer (600) can serve as a reference for the vibration and inclination angle of the entire driving unit.

[0186] Since the motor unit (500) is not fixed to other components of the garment treatment device but is only fixed to the reducer (600), when vibration or external force is transmitted to the driving unit, the motor unit (500) can always be tilted or vibrated simultaneously with the reducer (600) when the reducer (600) tilts or vibrates.

[0187] As a result, the reducer (600) and the motor unit (500) can form a single vibration system, and the reducer (600) and the motor unit (500) can be maintained in a fixed state without moving relative to each other.

[0188] Among the motor section (500), the stator (510) can be directly coupled to and fixed to the reducer (600). As a result, the position at which the drive shaft (530) is installed relative to the reducer (600) may not change. The center of the drive shaft (530) and the center of the reducer (600) may be arranged to coincide with each other, and the drive shaft (530) may rotate while maintaining the same axis as the center of the reducer (600).

[0189] The first axis (M1) may refer to an imaginary line extending in the forward and backward direction along the center of rotation of the drum (200). That is, the first axis (M1) may be provided parallel to the X-axis.

[0190] The second axis (M2) and the third axis (M3) may refer to imaginary lines extending from the front to the rear upper side of the garment processing device. That is, the second axis (M2) and the third axis (M3) may be provided parallel to the XZ plane or orthogonal to the Y axis.

[0191] The first axis (M1) and the second axis (M2) can intersect each other in the reducer (600). In addition, the first axis (M1) and the third axis (M3) can intersect in the mounting portion (425).

[0192] The above reducer (600) and the above motor unit (500) can be designed to be arranged along the first axis (M1) parallel to the ground when there is no load on the drum (200) or the above motor unit (500) is not operating.

[0193] However, when vibration occurs in the drum (200) or motor unit (500), the vibration is transmitted to the reducer (600), causing the reducer (600) to tilt, thereby temporarily causing the reducer (600) to tilt along the second axis (M2).

[0194] At this time, since the motor unit (500) is coupled to the reducer (600), it can vibrate or tilt together with the reducer (600). Accordingly, the motor unit (500) can be arranged parallel to the reducer (600) on the second axis (M2). Accordingly, the driving shaft and the drum rotation shaft can also be arranged parallel along the second axis (M2).

[0195] As a result, even if the reducer (600) is tilted, the motor unit (500) can move integrally with the reducer (600), and the driving shaft and the drum rotation shaft can maintain coaxiality.

[0196] The above-described reducer (600) may be fixedly coupled to the rear plate (420). In this case, since the reducer (600) will tilt or vibrate while being coupled to the rear plate (420), it can be seen that the rear plate (420) serves as the center of a vibration system including the reducer (600), the motor unit (500), and the drum (200). In this case as well, the motor unit (500) may not be directly coupled to the rear plate (420), but may be fixedly coupled only to the reducer (600).

[0197] The above reducer (600), the motor unit (500), and the drum (200) are arranged in parallel along the first axis (M1), and the reducer (600) can be inclined parallel to the third axis (M3) by vibration of the drum (200) or the motor unit (500). The third axis (M3) can pass through the reducer (600) coupled to the rear plate (420). At this time, since the reducer (600) and the motor unit (500) are coupled, the motor unit (500) can also be inclined parallel to the third axis (M3) in the same manner as the reducer (600).

[0198] Finally, the motor unit (500) and the drum (200) are coupled to the reducer (600), so that the motor unit (500) and the drum (200) can tilt parallel to each other or vibrate simultaneously with respect to the reducer (600).

[0199] The aforementioned coaxiality and coincidence do not imply physically perfect coaxiality and coincidence, but rather allow for a range of error that is mechanically acceptable or a range that a person skilled in the art would consider coaxiality or coincidence. For example, the range in which the drive shaft (530) and the drum rotation shaft (6341) are misaligned by less than 5 degrees can be defined as coaxiality or coincidence. However, such angle values ​​are merely examples, and the allowable error in design may vary.

[0200] Since the above drive shaft (530) rotates relative to the reducer (600) but is fixed to prevent tilting, and the stator (510) is also fixed to the reducer (600), the gap between the stator (510) and the rotor (520) can always be maintained. As a result, collision between the stator (510) and the rotor (520) can be prevented, and noise or vibration that may occur due to the center of rotation of the rotor (520) changing while rotating the stator (510) can be fundamentally blocked.

[0201] The drum rotation shaft (6341) is provided to extend toward the drum (200) from within the reducer (600), and can vibrate and tilt together with the reducer (600). That is, the drum rotation shaft (6341) is provided to rotate in the reducer (600), but the installed position can be fixed. As a result, the drum rotation shaft (6341) and the drive shaft (530) can always be arranged in parallel and form a coaxial connection. In other words, the center of the drum rotation shaft (6341) and the center of the drive shaft (530) can be maintained in a state where they are aligned with each other.

[0202] Meanwhile, a sealing portion (450) may be provided between the drum back surface (220) and the rear plate (420). The sealing portion (450) may seal the space between the drum back surface (220) and the rear plate (420) so that air introduced into the duct portion (423) of the rear plate (420) is prevented from leaking out and is introduced into the suction hole (224).

[0203] The above sealing portion (450) may be arranged on each of the outer and inner surfaces of the duct portion (423). A first sealing portion (451) may be provided on the radially outer side of the duct portion (423), and a second sealing portion (452) may be provided on the radially inner side. The first sealing portion (451) may prevent hot air from leaking outward in the radial direction between the drum back surface (220) and the duct portion (423), and the second sealing portion (452) may prevent hot air from leaking outward in the radial direction between the drum back surface (220) and the duct portion (423).

[0204] In other words, the sealing portion (450) may be respectively positioned on the radially outer and inner sides of the suction hole (224). The first sealing portion (451) may be positioned on the radially outer side of the suction hole (224), and the second sealing portion (452) may be positioned on the radially inner side of the suction hole (224).

[0205] In order to prevent hot air from leaking out, the sealing portion (450) is preferably provided to contact both the drum back surface (220) and the rear plate (420). Since the drum (200) rotates during the operation of the clothing treatment device, continuous friction is applied to the sealing portion (450) by the drum back surface (220). Therefore, it is preferable that the sealing portion (450) be provided with a material that can seal between the drum back surface (220) and the duct portion (423) without deteriorating in performance even with the frictional force and frictional heat generated by the rotation.

[0206] Meanwhile, a motor unit (500) or a reducer (600) may be coupled to the rear of the rear plate (420). Since the rear plate (420) may be formed of a thin iron plate material, there is a possibility that it may bend or be deformed due to the load transmitted to the reducer (600) by the reducer (600) and the drum (200). That is, the rigidity of the rear plate (420) needs to be secured in order to install the reducer (600), the motor unit (500), etc.

[0207] For this purpose, the rear plate (420) may further include a bracket (700) to reinforce the joint rigidity. The rear plate (420) may additionally be coupled with a bracket (700), and the reducer (600) and the motor unit (500) may be coupled to the rear plate (420) by the bracket (700).

[0208] The reducer (600) can be simultaneously coupled with the bracket (700) and the rear plate (420). The reducer (600), the rear plate (420), and the bracket (700) can be simultaneously coupled by using a fastening member. The rear plate (420) can be rigidly coupled with the bracket (700). The reducer (600), the motor unit (500), and the like can be coupled to the rear plate (420) with secured rigidity.

[0209] The reducer (600) may be first coupled to the above bracket (700) and then the bracket (700) may be coupled to the rear plate (420). That is, the reducer may not be directly coupled to the rear plate (420) but may be fixed to the rear plate (420) through the bracket (700).

[0210] Meanwhile, when the motor unit (500) or the reducer (600) is coupled to the rear of the rear plate (420), the motor unit (500) and the reducer (600) may be exposed to the outside. Therefore, it is necessary to prevent the motor unit (500) from being exposed by being coupled to the rear of the rear plate (420). In addition, the duct unit (423) may be heated by hot air. Therefore, it may be necessary to insulate the rear surface of the duct unit (423).

[0211] The rear cover (430) may be coupled to the rear of the rear plate (420) to prevent the duct section (423) and the motor section (500) or reducer (600) from being exposed to the outside. The rear cover (430) may be positioned apart from the duct section (423) and the driving section.

[0212] The rear cover (430) has the effect of preventing the motor section (500) from being damaged by external interference or from heat loss occurring through the duct section (423) and reducing drying efficiency.

[0213] Figure 5 illustrates the base structure of the clothing treatment device of the present invention.

[0214] The above base (800) may be arranged with the circulation duct (820) extending from one side. The circulation duct (820) may be arranged to be offset from the center of the base (800). The circulation duct (820) may be arranged to extend in the front-back direction.

[0215] The above circulation duct (820) may be formed integrally with the base (800) and may be provided in the shape of a duct with an open upper portion. The duct cover portion (830) may be detachably coupled to the upper surface of the circulation duct (820) so that a flow path within the circulation duct (820) may be formed.

[0216] The above duct cover part (830) may be formed to be shorter than the length of the circulation duct (820), or may have one end formed in a ring shape to form the inflow duct (821).

[0217] Among the above circulation ducts (820), the moving duct (822) can be arranged to extend in the forward and backward directions. Both the evaporator (910) and the condenser (920) can be mounted inside the moving duct (822).

[0218] The above inlet duct (821) may be formed to have a width longer than the above moving duct (822). The above inlet duct (821) may be arranged so that most of the area overlaps the inlet (211) of the drum (200) in the vertical direction. As a result, the above inlet duct (821) can suck in air discharged from the drum (200).

[0219] In the above base (800), an external area of ​​the circulation duct (820) may be formed with a device installation section (810) where electrical components are installed. The device installation section (810) is an area on the other side of the circulation duct (820) in the base (800), and components such as a compressor (930) may be installed, a pump (861) that discharges water discharged from the circulation duct (820) to the outside, a washing section (1000) that washes the circulation duct (820), and a steam section (2000) that supplies steam to the inside of the circulation duct (820) may be installed.

[0220] Since the above circulation duct (820) is arranged in a forward-backward direction on one side of the base (800), the device installation unit (810) can be provided so that it can be accessed from the rear or front of the cabinet (100) without interference with the circulation duct (820). Accordingly, it can be easy to install or repair / replace components or electrical equipment arranged in the device installation unit (810) from the base (800).

[0221] The above device installation unit (810) may include a water collection unit (860) in which water discharged from the moving duct (822) is collected.

[0222] The above water collection unit (860) may be sunken downward from the base (800) to form a space in which water is stored. The bottom surface of the water collection unit (860) may be formed lower than the bottom surface of the moving duct (822).

[0223] The above collection unit (860) may be arranged on one side of the moving duct (822) and may be provided so as to be in communication with the inside of the moving duct (822).

[0224] The above water collection unit (860) can collect water condensed from the above evaporator (910). In addition, the above water collection unit (860) can also collect water supplied from the washing unit (1000) described below.

[0225] The above device installation unit (810) may further include a pump (861) mounted on the water collection unit (860) to discharge water collected in the water collection unit (860). The pump (861) may provide power to discharge water collected in the water collection unit (860) into a water storage tank (120) or to the outside of the cabinet (100).

[0226] Additionally, the pump (861) may be provided to supply water collected in the water collection unit (860) to the washing unit (1000) to wash the inside of the circulation duct (820).

[0227] The above base (800) does not have a motor unit (500) installed. Accordingly, the water collecting unit (860) can be provided with a diameter much larger than the pump (861). For example, the water collecting unit (860) can be provided with a diameter more than twice that of the pump (861). As a result, the water collecting unit (860) can sufficiently store not only the water collected from the evaporator (910) but also the water supplied from the washing unit (1000).

[0228] The above device installation unit (810) may include a washing unit (1000) that supplies water to the inside of the circulation duct (820) to wash the inside of the circulation duct (820).

[0229] The above washing unit (1000) can receive water from the outside and wash the inside of the circulation duct (820) with clean water (direct water), and can wash the evaporator (910) placed inside the circulation duct (820) or a filter placed upstream of the evaporator (910) based on the direction in which air is introduced. Hereinafter, washing the components such as the evaporator (910) and the filter placed in front of the evaporator (910) with water sprayed from the washing unit (1000) is collectively referred to as washing the evaporator (910).

[0230] The above device installation unit (810) may further include a steam generating unit (8200) that can receive water and generate steam.

[0231] The steam generator (8200) may be mounted on the base (800) and configured to supply steam into the circulation duct (820). As a result, the steam may be supplied into the drum (200) via the circulation fan (950). In addition, the steam discharged from the steam generator (2000) may also be supplied to the evaporator (910) and the condenser (920), so that the evaporator (910) and the condenser (920) may be sterilized.

[0232] The above base (800) may be provided with a steam mounting portion (890) that is positioned in front of the water collection portion (860) and on which a steam generating portion (2000) is mounted.

[0233] The above steam mounting portion (890) can protrude upward from the base (800) to form a space in which the steam generating portion (2000) can be supported.

[0234] Figure 6 illustrates an example of a configuration installed in the above device installation unit.

[0235] The above washing unit (1000) may be equipped with a water supply washing unit that can wash the inside of a circulation duct (820) or wash an evaporator (910) by receiving water from an external water source.

[0236] The washing unit (1000) may include a water supply valve (1100) that is mounted on the base (800) or fixed to the back of the cabinet (100) to receive water from an external water source, a supply pipe (1200) that transmits water supplied from the water supply valve (1100), and a supply nozzle (1300) that is disposed on the upper portion of the circulation duct (820) and discharges water supplied from the supply pipe (1200) into the interior of the circulation duct (820).

[0237] The garment treatment device of the present invention may include a water supply bracket (880) that secures the water supply valve (1100). The water supply bracket (800) may be provided in a plate shape and may be provided with a material having stronger rigidity than the base (800). For example, the water supply bracket (800) may be provided with a metal material. Accordingly, even if water at a high water pressure is supplied to the water supply valve (1100) or vibration is transmitted to the water supply valve (1100), the position where the water supply valve (1100) is installed is fixed, thereby preventing risks such as water leakage.

[0238] The above water supply bracket (880) may be fixed by being joined to the back surface of the base (800), or may be fixed to the back surface of the cabinet (100) and placed upwardly spaced from the base (800).

[0239] The above water supply valve (1100) may be provided to supply water not only to the supply nozzle (1300) but also to the steam generator (2200). This may be advantageous in terms of energy and control / management compared to a case where the water supply valve (1100) is provided separately.

[0240] To this end, the water supply valve (1100) may include a main valve (1110) that communicates with water from an external water supply source passing through a water supply bracket (800), a supply valve (1120) that receives water from the main valve (1110) and supplies it to the supply nozzle (1300), and a steam valve (1130) that receives water from the main valve (1110) and supplies it to a steam generator (1300).

[0241] The above supply valve (1120) can be connected to one end of the above supply pipe (1200), and the above steam valve (1130) can be connected to one end of the steam pipe (2200) described later.

[0242] In the following, in all configurations where water flows, the first region is defined as the area where water flows into the configuration, and the last region is defined as the area where the introduced water finally reaches in the process of flowing without backflow in the configuration.

[0243] The above main valve (1110), the above supply valve (1120), and the above steam valve (1130) may be provided to be sequentially connected, or may be provided to be simultaneously connected.

[0244] The above main valve (1110) can be controlled to supply all water to the above supply valve (1120) and the above steam valve (1130) or to block all water.

[0245] Additionally, the supply valve (1120) may be provided to selectively open and close the supply pipe (1200) even if water is supplied from the main valve (1110).

[0246] Additionally, the steam valve (1130) may be provided to selectively open and close the steam pipe (2200) even if water is supplied from the main valve (1110) or the supply valve (1120).

[0247] Accordingly, whether or not water is supplied from the external water source can be primarily determined through the main valve (1110), and secondarily determined through the supply valve (1120) and steam valve (1130). As a result, even if some of the water supply valves (1110) break down or become uncontrollable, water can be prevented from being supplied arbitrarily through the water supply valves (1110).

[0248] The above supply nozzle (1300) may be provided with multiple supply pipes (1200) depending on whether the euro is divided. In this case, the supply valves (1120) may also be provided with a number corresponding to the supply pipes (1200).

[0249] For example, in the case where the above supply pipe (1200) is provided in two, it may include a first supply valve (1121) that is connected to one of the supply pipes (1200) and receives water from the main valve (1100), and a second supply valve (1122) that is connected to the other of the supply pipes (1200) and receives water from the main valve (1100) or the first supply valve (1121).

[0250] The above supply nozzle (1300) may be placed on the upper portion of the circulation duct (820). For example, it may be mounted and fixed to the duct cover portion (830).

[0251] The above supply nozzle (1300) can be arranged to extend along the width direction of the circulation duct (820). As a result, water can be evenly sprayed inside the circulation duct (820).

[0252] For example, the width of the supply nozzle (1300) may be provided to correspond to the width of the circulation duct (820). As a result, water can be evenly supplied to the entire width area of ​​the circulation duct (820).

[0253] The above evaporator (910) may be exposed to foreign substances such as lint discharged from the drum (200) by contacting the air supplied from the inlet duct (821). The supply nozzle (1300) may be positioned at the top of the evaporator (910). As a result, foreign substances such as lint attached from the top to the bottom of the evaporator (910) can be washed with water.

[0254] Meanwhile, the front surface of the evaporator (910) may be more prone to foreign substances such as lint being attached than the back surface. The supply nozzle (1300) may be positioned at the front upper portion of the evaporator (910). The supply nozzle (1300) may be positioned closer to the front surface than the back surface of the evaporator (910). As a result, foreign substances that are concentratedly attached to the front surface of the evaporator (910) may be washed away with water.

[0255] The water used to wash the evaporator (910) can also wash the inner surface of the circulation duct (820). In addition, at least a portion of the water discharged from the supply nozzle (1300) can wash down both sides of the circulation duct (820). The water discharged from the supply nozzle (1300) can ultimately be collected on the bottom surface of the circulation duct (820) and discharged to the water collection unit (860). In this process, all foreign substances that have settled on the bottom surface of the circulation duct (820) can be washed away.

[0256] As a result, the control unit of the clothing treatment device of the present invention can wash both the evaporator (910) and the inside of the circulation duct (820) by controlling the water supply valve (1100).

[0257] The water collecting unit (860) may be disposed on one side of the evaporator (910) so as to collect water condensed in the evaporator (910). The water collecting unit (860) may be disposed closer to the evaporator (910) than to the condenser (920). As a result, the supply nozzle (1300) may be disposed to overlap the water collecting unit (860) in the width direction, and the water collecting unit (860) may be disposed on one side of the supply nozzle (1300).

[0258] Hereinafter, the forward / backward direction and the width direction may be defined based on the clothing treatment device. For example, the extension direction of the circulation duct may correspond to the forward / backward direction, and the cross-sectional direction of the circulation duct perpendicular to the forward / backward direction may correspond to the width direction.

[0259] The above steam generating unit (2000) may include a steam case (2100) that is mounted on the base (800) and stores water, a steam pipe (2200) that receives water from the water supply valve (1100) and delivers it to the steam case (2100), a supply pipe (2400) that moves steam discharged from the steam case (2100), and a steam nozzle (2300) that is connected to the end of the supply pipe (2400) and discharges steam into the inside of the circulation duct (820).

[0260] The steam case (2100) can be installed in front of the water collection unit (860). As a result, the steam case (2100) can be easily exposed in front of the cabinet (100), making at least one of installation, maintenance, and residual water discharge easier.

[0261] The above steam case (2100) can be installed in the steam mounting portion and have a space for storing water, and a heater that heats the water to generate steam can be installed inside.

[0262] The steam pipe (2200) may have one end connected to the steam valve (1130) and the other end coupled to the steam case (2100). The other end of the steam pipe (2200) may be coupled above the lower portion of the steam case (2100) to prevent water from flowing backward.

[0263] The above supply pipe (2400) may be separated and spaced from the steam pipe (2200) and connected to the steam case (2100). One end of the supply pipe (2400) may be positioned closer to the upper portion than the lower portion of the steam case (2100). As a result, steam generated by heating water may be automatically discharged to the supply pipe (2400) due to the density difference.

[0264] The above steam nozzle (2300) may be positioned above the circulation duct (820) to supply steam into the interior of the circulation duct (820). The steam nozzle (2300) may be mounted on the duct cover (830).

[0265] The above steam nozzle (2300) may be provided to extend in the width direction of the circulation duct (820). Accordingly, the steam nozzle (2300) can supply steam to the widest possible area of ​​the circulation duct (820) to sterilize the inside of the circulation duct (820).

[0266] The above steam nozzle (2300) may be placed on the upper part of the above evaporator (910).

[0267] However, the steam nozzle (2300) may be placed apart from the direct water line (1300) to avoid interference with the supply nozzle (1300).

[0268] The above supply nozzle (1300) may be arranged to overlap vertically on the front surface of the evaporator (910) to increase the efficiency of washing the evaporator (910).

[0269] In this case, if the steam nozzle (2300) is positioned downstream or rearward of the supply nozzle (1300), there is a concern that the front surface of the evaporator (910) may not be exposed to steam. Therefore, the steam nozzle (2300) may be positioned forward of the supply nozzle (1300). Accordingly, the steam sprayed from the steam nozzle (2300) can move along the extension direction of the circulation duct (820), and in this process, can pass through the entire area of ​​the evaporator (910).

[0270] Steam passing through the evaporator (910) can sterilize the evaporator (910), but can also provide heat to the refrigerant passing through the evaporator (910). As a result, the evaporator (910) can absorb sufficient heat and transfer it to the compressor (930).

[0271] The garment treatment device of the present invention can control the heater, etc., contained in the steam generating unit (2000) at the beginning of the drying cycle to supply steam to the evaporator (910), thereby inducing the temperature of the refrigerant discharged from the compressor (930) to quickly reach the target temperature. As a result, the drying time can be shortened and the drying efficiency can be increased.

[0272] The above supply pipe (1200) may be made of an elastic material. For example, the above supply pipe (1200) may be made of a rubber hose or the like.

[0273] The above supply pipe (2400) and the steam pipe (2200) may be made of an elastic material. For example, the above supply pipe (2400) and the steam pipe (2200) may be made of a rubber hose or the like.

[0274] Figure 7 illustrates a state in which the base of the garment treatment device of the present invention is viewed from the front side.

[0275] When multiple flow paths are formed in the supply nozzle (1300) and the flow paths are partitioned / separated, the supply pipe (1200) may include a first supply pipe (1221) having one end connected to the first supply valve (1121) and the other end connected to the supply nozzle (1300), and a second supply pipe (1222) having one end connected to the second supply valve (1122) and the other end connected to the supply nozzle (1300). As a result, even when the water pressure or quantity of water supplied through the main valve (1110) is insufficient, the quantity and water pressure of water sprayed per unit area from the supply nozzle (1300) can be secured.

[0276] The above water collection unit (860) may include a water collection body (862) that provides a space for collecting water discharged from the circulation duct (820), and a water collection cover (863) that shields the water collection body (862) and maintains the internal pressure of the water collection body (862).

[0277] The above water collection cover (863) may have a space formed in the center where the pump (861) is installed.

[0278] The above water collection unit (860) may include a drain pipe (864) that guides water discharged from the water collection body (862). The drain pipe (864) may be connected to the water collection cover (863) or the pump (861), and the other end may be connected to a drain located outside the water storage tank (120) or the cabinet (100).

[0279] The above water collection unit (860) may include a support bracket (865) that is fixed to the back surface of the base (800) or the cabinet (100) and fixes the end of the drain pipe (864). The drain pipe (864) may be provided to pass through the support bracket (865). In this case, the support bracket (864) may support the outer circumferential surface of the drain pipe (864). Accordingly, even if high-pressure water moves through the drain pipe (864), the position of the drain pipe (864) can be fixed, and the drain pipe (864) can be prevented from being arbitrarily separated from the pump (861), etc.

[0280] Figure 8 illustrates the water supply path of the clothing treatment device of the present invention.

[0281] When the above water supply valve (1100) is opened, water supplied from an external water source can be supplied through the main valve (1110).

[0282] When the main valve (1110) is opened, water is supplied to the supply valve (1120), and when the supply valve (1120) is opened, water can be supplied to the supply nozzle (1300) through the supply pipe (1200).

[0283] For example, when the first supply valve (1121) is opened, water can be supplied to the supply nozzle (1300) through the first supply pipe (1210), and when the second supply valve (1122) is opened, water can be supplied to the supply nozzle (1300) through the second supply pipe (122).

[0284] After the water supplied through the supply nozzle (1300) washes the inside of the evaporator (910) and the circulation duct (820), it can be collected in the water collection unit (860).

[0285] When the main valve (1110) is opened, water can be supplied to the steam valve (1130), and when the steam valve (1130) is opened, water can be supplied to the steam case (2100) through the steam pipe (2200).

[0286] Steam generated in the steam case (2100) can be sprayed to the steam nozzle (2300) through the supply pipe (2400), and steam condensed in the evaporator (910) or condensed in the circulation duct (820) can be collected in the water collection unit (860).

[0287] The water collected in the above collection unit (860) can be discharged along the drain pipe (864) when the pump (861) is driven. The water discharged through the drain pipe (864) can pass through the support bracket (865) and be discharged into the water storage tank (120) or a sewer.

[0288] The above drain pipe (864) may be made of an elastic material. For example, the above drain pipe (864) may be made of a rubber hose.

[0289] Figure 9 illustrates an example structure of a steam nozzle and a supply nozzle.

[0290] Water supplied from the above steam pipe (2200) can be supplied to the steam case (2100), and steam heated in the steam case (2100) can move to the steam nozzle (2300) while moving through the supply pipe (2400).

[0291] The above steam nozzle (2300) may include a steam body (2310) through which steam supplied from the supply pipe (2400) passes, a communication pipe (2320) provided to connect the steam body (2310) and the supply pipe (2400), and a steam discharge unit (2330) that sprays steam supplied from the steam body (2310) into the inside of the circulation duct (820).

[0292] The above steam body (2310) may be provided in a case shape in which the length in the width direction is longer than the width in the front-back direction.

[0293] The steam body (2310) may be positioned in front of the evaporator (910) and may be positioned above the evaporator (910). At least a portion of the steam body (2310) may be positioned below the upper portion of the circulation duct (820) to more effectively supply steam to the evaporator (910).

[0294] To this end, the duct cover part (830) may be formed to be sunken downward so that the area where the steam body (2310) is mounted is positioned lower than the area where the circulation duct (820) is installed.

[0295] The above-mentioned communication pipe (2310) may be provided to extend outward from one side of the steam body (2310). The end of the communication pipe (2310) may be connected to the supply pipe (2400).

[0296] Steam introduced along the above-mentioned communication pipe (2310) can move along the length of the steam body (2310) and be discharged to the steam discharge unit (2330).

[0297] The water condensed in the steam body (2310) can be discharged through the steam discharge unit (2330) so as not to block the inside of the steam body (2310).

[0298] For this purpose, the steam discharge unit (2330) may be provided to extend outward from the lower portion of the steam body (2310).

[0299] The steam discharge unit (2330) may be provided in the shape of a slit protruding from the lower portion of the steam body (2310). In this case, the steam discharge unit (2230) may also be formed so that the length in the width direction is longer than the width in the front-back direction.

[0300] Additionally, the steam discharge unit (2330) may be provided in the shape of a pipe protruding from the lower portion of the steam body (2310).

[0301] The steam discharge unit (2330) may be formed to extend rearward from the steam body (2310) toward the evaporator (910). The steam discharge unit (2230) may extend slantedly rearward from the lower portion of the steam body (2310). Accordingly, steam discharged from the steam discharge unit (2330) may be supplied to the front surface of the evaporator (910).

[0302] The above supply nozzle (1300) may include a nozzle case (1310) that provides a path for temporarily storing or moving water supplied from the supply pipe (1200), a connection pipe (1320) that connects the nozzle case (1310) and the supply pipe (1200), and a spray unit (1330) that sprays water supplied to the nozzle case (1310) into the inside of a circulation duct (820).

[0303] The above nozzle case (1310) may be provided in a case shape in which the length in the width direction is longer than the width in the front-back direction. The nozzle case (1310) may form a flow path inside that extends in the width direction of the circulation duct (820).

[0304] The nozzle case (1310) may be arranged so that at least a portion thereof overlaps the evaporator (910) in the vertical direction. For example, the nozzle case (1310) may be arranged so that at least a portion thereof overlaps the front surface of the evaporator (910). This allows water supplied to the nozzle case (1310) to be guided to wash the evaporator (910).

[0305] The above connecting pipe (1320) may be connected to one end of the nozzle case (1310) to supply water into the inside of the nozzle case (1310).

[0306] The nozzle case (1310) may be positioned higher than the evaporator (910). For example, the nozzle case (1310) may be mounted on the upper surface of the duct cover part (830), and the duct cover part (830) may have a through hole formed at a position corresponding to the spray part (1330). The spray part (1330) may be provided to penetrate the nozzle case (1310) so that water supplied to the nozzle case (1310) may fall by gravity. Accordingly, even if the water pressure of the water supplied to the nozzle case (1310) is somewhat weak, a drop that allows the water falling from the spray part (1330) to wash foreign substances on the evaporator (910) by gravity may be secured. The spray part (1330) may be positioned at a position corresponding to the front surface of the evaporator (910).

[0307] The above-mentioned injection unit (1330) may include an injection hole (1333) that discharges water by penetrating the nozzle case (1310). The injection hole (1333) may be positioned at a position to spray water in the height direction from the front surface of the evaporator (910).

[0308] For example, the injection hole (1333) may be arranged to overlap the front surface of the evaporator (910) in the height direction.

[0309] Figure 10 illustrates an internal embodiment of the nozzle case.

[0310] The above nozzle case (1310) may include multiple passages (A, B) that receive water from the main valve (1100), and the multiple passages may be completely partitioned and separated. That is, water supplied to one passage (A) may be blocked from moving to another passage (B).

[0311] The supply nozzle (1300) of the garment treatment device of the present invention may be provided with a plurality of channels arranged in the nozzle case (1310) and capable of independently supplying water to each of the plurality of channels.

[0312] For example, the supply nozzle (1300) may have a connection pipe (1320) arranged in each of the sections of the nozzle case (1310), the water supply valve (1100) may have a plurality of supply valves (1120) that independently supply water to a plurality of the connection pipes (1320), and the supply pipe (1200) may be provided in multiple numbers to individually connect a plurality of the connection pipes (1320) and a plurality of supply valves (1120).

[0313] Of course, only one euro is formed inside the nozzle case (1310), and multiple nozzle cases (1310) may be provided and arranged in the width direction of the circulation duct (820).

[0314] However, if the nozzle case (1310) is provided in a single unit, the deviation in the position where the nozzle case (1310) is installed in the duct cover part (830) for each product can be reduced, and the installation process can be shortened.

[0315] Therefore, the following description is based on the assumption that a single nozzle case (1310) is provided and multiple flow paths are arranged inside.

[0316] The supply nozzle (1300) of the garment treatment device of the present invention may have at least two internal channels within the nozzle case (1310). The following description is based on the arrangement of two channels within the supply nozzle (1300) of the present invention, but this is merely an example, and three or more channels may be arranged within the nozzle case.

[0317] The above supply nozzle (1300) may have a connecting pipe (1320) arranged at one end in the width direction of the nozzle case (1310).

[0318] A plurality of paths arranged and partitioned inside the above nozzle case (1310) can be arranged along the width direction of the circulation duct (820) or the evaporator (910).

[0319] For example, the nozzle case (1310) may include a first flow path (A) provided to spray water in an area adjacent to the connecting pipe (1320), and a second flow path (B) provided to spray water in an area further from the connecting pipe (1320) in the width direction than the first flow path (A).

[0320] The clothing treatment device of the present invention can individually supply water to the first flow path (A) and the second flow path (B) provided in the nozzle case (1310) by individually controlling the opening and closing of the first supply valve (1121) and the second supply valve (1122).

[0321] Accordingly, when the water pressure or quantity of an external water source is insufficient, the pressure and quantity of water supplied to the first flow path (A) and the second flow path (B) can be secured by selectively and sequentially opening and closing the first supply valve (1121) and the second supply valve (1122).

[0322] Figure 11 illustrates an embodiment of a supply nozzle of the garment treatment device of the present invention.

[0323] The above nozzle case (1310) may be formed to be extended in the width direction in order to evenly wash the supplied water across the entire width direction of the circulation duct (820) or the entire front surface of the evaporator (910) as described above.

[0324] The above nozzle case (1310) is installed in an area positioned above the evaporator (910), and the water supply valve (1100) is installed in an area close to the back surface of the cabinet (100), so it may be reasonable for the supply pipe (1200) to be connected to the back surface of the nozzle case (1310) facing the water supply valve (1100).

[0325] In this case, a connecting pipe (1320) may be provided at the rear of the nozzle case (1310). However, since the nozzle case (1310) is placed on the upper part of the duct cover part (830) or the circulation duct (820), it is placed to face the lower part of the drum (200). In this state, if the supply pipe (1200) is connected to the rear of the nozzle case (1310), the supply pipe (1200) is also placed to face the lower part of the drum (200), and there is a concern that the supply pipe (1200) may interfere with the rotating drum (200).

[0326] To prevent this, the water supply valve (1100) may also be positioned on the side of the moving duct (822), and the supply pipe (1200) may also extend from the side of the moving duct (822). Accordingly, the supply pipe (1200) may extend to the nozzle case (1310) at a position lower than the upper surface of the duct cover part (830) or the circulation duct (820). As a result, the supply pipe (1200) may be prevented from interfering with the drum (200).

[0327] The above supply pipe (1200) may be arranged at a position lower than the upper surface of the duct cover (830) or the circulation duct (820) on one side of the moving duct (822) facing the water collection unit (860). Therefore, it may be most efficient for the supply pipe (1200) to be coupled to one end of the nozzle case (1310) facing the device installation unit (810) corresponding to the side of the moving duct (822). To this end, the supply nozzle (1300) may arrange the connection pipe (1320) on one end of the nozzle case (1310).

[0328] Meanwhile, the water supply valve (1100) may be positioned at a position at least partially lower than the upper surface of the duct cover (830) or the circulation duct (820).

[0329] The supply nozzle (1300) of the present invention may include a nozzle passage (1340) disposed inside the nozzle case (1310) and through which water supplied from the connecting pipe (1320) moves.

[0330] The above nozzle flow path (1340) can extend from one end of the nozzle case (1310) toward the other end. As a result, water supplied from one end of the nozzle case (1310) can be delivered to the other end of the nozzle case (1310), and water can be supplied in the width direction of the circulation duct (820).

[0331] All configurations of the above nozzle flow path (1340) can be described based on upstream and downstream along the direction in which water flowing from the connecting pipe (1320) flows.

[0332] The above nozzle flow path (1340) can be arranged in multiple sections inside the nozzle case (1310).

[0333] The supply nozzle (1300) of the present invention may further include a partition (1350) that divides the plurality of flow paths and blocks water from communicating or moving between the plurality of flow paths.

[0334] The above nozzle flow path (1340) may include a first flow path (A) that forms a flow path for moving water supplied from the connecting pipe (1320) inside the nozzle case (1310), and a second flow path (B) that is separated from the first flow path (A) and forms a flow path for moving water supplied from the connecting pipe (1320).

[0335] The above second euro (B) can be arranged in the width direction with the above first euro (A).

[0336] The second flow path (B) may be provided to move the water supplied from the connecting pipe (1320) further to the other end of the nozzle case (1310) than the first flow path (A).

[0337] The above partition wall (1350) may be provided to separate the first flow path (A) and the second flow path (B) inside the nozzle case (1310).

[0338] The above nozzle flow path (1340) may include a spray flow path (1342) that extends in the width direction of the nozzle case (1310) inside the nozzle case (1310) and discharges water.

[0339] When the above nozzle flow path (1340) is provided in multiple parts, such as a first flow path (A) and a second flow path (B), the injection flow path (1342) may include a first injection flow path (1342a) arranged in the first flow path (A) and a second injection flow path (1342b) arranged in the second flow path (B).

[0340] The first injection path (1342a) and the second injection path (1342b) can be arranged in the width direction inside the nozzle case (1310).

[0341] The first injection path (1342a) and the second injection path (1342b) are arranged in parallel in the width direction, so that water can be supplied intensively to the area that requires the most cleaning among the evaporator (910) and the circulation duct (820).

[0342] The second injection path (1342b) may be positioned further away from the first injection path (1342a) than the connecting pipe (1320). That is, the first injection path (1342a) may be positioned closer to one end of the nozzle case (1310), and the second injection path (1342b) may be positioned closer to the other end of the nozzle case (1310).

[0343] The first injection path (1342a) and the second injection path (1342b) may be separated by a partition wall (1350). The partition wall (1350) may be placed between the first injection path (1342a) and the second injection path (1342b).

[0344] The above connecting pipe (1320) may be arranged at one end of the nozzle case (1310) and may be provided to correspond to the number of nozzle flow paths (1340). The connecting pipe (1320) may include a first connecting pipe (1320a) that supplies water to the first injection flow path (1342a) and a second connecting pipe (1320b) that supplies water to the second injection flow path (1342b).

[0345] The first connecting pipe (1320a) and the second connecting pipe (1320b) can both be provided in the shape of a pipe extending from one end of the nozzle case (1310) and can be arranged spaced apart from each other in the front-rear direction.

[0346] The nozzle flow path (1340) of the present invention may further include an intake flow path (1341) that is arranged between the connecting pipe (1320) and the injection flow path (1342) and guides water supplied from the connecting pipe (1320) to the injection flow path (1342).

[0347] The above-mentioned intake passage (1341) may be blocked from communicating with the outside of the nozzle case (1310), and the above-mentioned injection passage (1342) may be provided to communicate with the outside of the nozzle case (1310).

[0348] The above-mentioned intake path (1341) may omit the injection part (1330), and the injection part (1330) may be formed only in the injection path (1342).

[0349] The above-mentioned intake passage (1341) extends downstream of the above-mentioned connecting pipe (1320) and can be positioned upstream of the above-mentioned injection passage (1342).

[0350] When the nozzle flow path (1340) is provided in multiple numbers, the intake flow path (1341) may include a first intake flow path (1341a) arranged between the first connecting pipe (1320a) and the first injection flow path (1342a), and a second intake flow path (1341b) arranged between the second connecting pipe (1320b) and the second injection flow path (1342b).

[0351] Meanwhile, the nozzle case (1310) may further include a nozzle cover (1313) that shields the nozzle passage (1340) from the outside, and may include a fastening member that connects the nozzle cover (1313) and the nozzle case (1310). The fastening member may penetrate at least one of the nozzle case (1310) and the nozzle cover (1313). To this end, the nozzle case (1310) may further include a fastening area (1344) to which the fastening member is connected.

[0352] The above-mentioned joining area (1344) can be extended in the width direction to secure a space in which a plurality of joining members are joined in the width direction of the nozzle case (1310) and the nozzle cover (1313).

[0353] The above-mentioned joining area (1344) may include a first joining area (1344a) arranged in the first flow path and a second joining area (1344b) arranged in the second flow path, and a partition wall (1350) may be arranged between the first joining area (1344a) and the second joining area (1344b).

[0354] The water supplied when the above water supply valve (1100) is opened may correspond to a turbulent flow rather than a laminar flow as it passes through the above supply pipe (1200).

[0355] The above-mentioned intake channel (1341) can serve to convert the water into a laminar flow or a near-laminar flow by guiding it evenly in the width direction even when the water in the turbulent form is received. Accordingly, the above-mentioned intake channel (1341) can induce the water to move at a constant flow rate to the above-mentioned injection channel (1342), thereby inducing the water to be evenly sprayed over the entire area of ​​the injection channel (1342).

[0356] Figure 12 illustrates a phenomenon that may occur in a supply nozzle equipped with Figure 11.

[0357] The above injection path (1342) may extend in the width direction of the evaporator (910) from the nozzle case (1310), and the injection unit (1330) may be provided to penetrate the nozzle case (1310) so as to connect the injection path (1342) and the outside of the nozzle case (1310).

[0358] When the nozzle flow path (1340) is provided in multiple units, the injection unit (1330) may include a first injection unit (1330a) disposed in the first flow path (A) to inject water flowing through the first injection flow path (1342a) to the outside of the nozzle case (1310), and a second injection unit (1330b) disposed in the second flow path (A) to inject water flowing through the second injection flow path (1342b) to the outside of the nozzle case (1310).

[0359] The above injection path (1342) and the injection unit (1330) may be formed in the nozzle case (1310) to be the same width as or longer than the width of the evaporator (910). As a result, the supply nozzle (1300) can wash the entire area from the upper to the lower portion of the evaporator (910).

[0360] The above-mentioned intake passage (1341) may be formed so as to be positioned outside one side of the evaporator (910) so as not to overlap with the evaporator (910) in the front-back direction. To this end, the nozzle case (1310) may be provided to be longer than the width of the evaporator (910) so as to form an area where the intake passage (1341) is spaced apart from the evaporator (910), and the injection passage (1342) and the injection unit (1330) may be positioned so as to overlap with the other side of the evaporator (910) in the vertical direction.

[0361] However, although the injection path (1342) and the injection unit (1330) discharge water in the entire area, a deficiency area (P1) may be formed in an area close to the water intake path (1341) where the amount of water injected is less than in other areas.

[0362] For example, when the nozzle flow path (1340) is provided in a single unit, the shortage area (P1) may be formed in an area of ​​the injection flow path (1342) close to the intake flow path (1341) or the connecting pipe (1320).

[0363] In addition, when the above-described direct injection flow path (1340) is provided in multiple units, the deficiency area (P1) may be formed in an area close to the first intake flow path (1341a) in the first injection flow path (1342A) arranged close to the connecting pipe (1320).

[0364] The above-mentioned shortage area (P1) can occur even when the water pressure of the water supplied from the water supply valve (1100) is high and the water quantity is abundant. Therefore, the above-mentioned shortage area (P1) can be understood as the water flowing directly into the water inlet (1341) from the connecting pipe (1320) is turbulent or close to turbulent, so the water flow is unstable and cannot be discharged to the injection unit (1330).

[0365] Figure 13 illustrates an additional embodiment of a supply nozzle of the garment treatment device of the present invention.

[0366] The supply nozzle (1300) of the present invention may be provided to block the formation of the above-mentioned deficiency area (P1).

[0367] Specifically, the supply nozzle (1300) of the present invention may be provided to extend the intake passage (1341) to a sufficient length so that the water supplied from the connecting pipe (1320) can be converted to laminar flow as much as possible and reach the injection passage (1342).

[0368] For example, the supply nozzle (1300) of the present invention has the water intake passage (1341) equal to or longer than the length of the injection passage (1342), so that water supplied from the connection pipe (1320) can reach the injection passage (1342) in a stable state.

[0369] For example, the injection path (1342) may be connected only to the end of the intake path (1341), but may extend parallel to the intake path (1341) in front and rear of the intake path (1341). For example, the supply nozzle (1300) of the present invention may arrange the intake path (1341) and the injection path (1342) in the front-back direction. Accordingly, even if the intake path (1341) becomes longer, the length of the injection path (1342) can be maintained.

[0370] In the case where the above nozzle flow path (1340) is provided in multiple numbers, the arrangement of the first intake flow path (1341a) and the first injection flow path (1342a) and the arrangement of the second intake flow path (1341b) and the second injection flow path (1342b) may be different from each other.

[0371] For example, the first intake passage (1341a) may be arranged rearward relative to the first injection passage (1342a), and the second intake passage (1341b) may be arranged forward relative to the second injection passage (1342b). Accordingly, even if the first injection passage (1342a) and the second injection passage (1342b) are arranged in parallel in the width direction, the first intake passage (1341a) and the second intake passage (1341b) may be extended to a sufficient length within the nozzle case (1310) without interfering with each other.

[0372] In the case where the above nozzle flow path (1340) is provided in multiple units, the second flow path (B) is provided such that the second intake flow path (1341b) is longer than the second injection flow path (1342b), so that the occurrence of the insufficient area (P1) in the entire area of ​​the second injection flow path (1342b) can be prevented. As a result, water can be smoothly sprayed in the entire area of ​​the second injection flow path (1342b).

[0373] In the case of the first flow path (A), the first inlet flow path (1341a) may be provided with a width equal to or longer than the first injection flow path (1342a). Accordingly, the water supplied from the first connecting pipe (1320a) can be stabilized while passing through the first inlet flow path (1341a), and the occurrence of a shortage area (P1) in the first injection flow path (1342a) can be prevented. As a result, water can be smoothly sprayed throughout the entire area of ​​the first injection flow path (1342a).

[0374] Meanwhile, the injection flow path (1342) of the present invention may be provided so as to extend in a direction different from the direction in which water is received from the inlet pipe (1320a). Accordingly, the direction in which water moves in the injection flow path (1342) may be set differently from the direction in which water moves in the inlet pipe (1320a) and the inlet flow path (1341).

[0375] For example, the above-mentioned intake passage (1341) and the above-mentioned injection passage (1342) can be arranged so as to overlap at least partly in the front-back direction.

[0376] One end of the above-mentioned intake passage (1341) may be positioned closer to the other end of the above-mentioned injection passage (1342) than one end of the above-mentioned injection passage (1342).

[0377] One end of the intake passage (1341) may be arranged in the forward-backward direction with the end of the injection passage (1342), and the other end of the intake passage (1341) and one end of the injection passage (1342) may be arranged in the forward-backward direction.

[0378] For example, water flowing into the intake channel (1341) may flow in one of the left and right directions, and water flowing into the injection channel (1342) may flow in the other of the left and right directions. Consequently, with respect to the nozzle case (1310), the direction of water passing through the intake channel (1341) may be set opposite to the direction of water passing through the injection channel (1342).

[0379]

[0380] As a result, water passing through the intake channel (1341) can reach one end of the injection channel (1342) while maintaining a uniform pressure and quantity of water, and then be supplied to the end of the injection channel (1342). Therefore, even when the quantity of water supplied from the water supply valve (1100) is insufficient or the water pressure of the water supplied from the water supply valve (1100) is low, the supply nozzle (1300) can uniformly collect water up to one end of the injection channel (1342) and then move it to the end of the injection channel (1342). As a result, water can be uniformly supplied to the entire section of the injection channel (1342).

[0381] Accordingly, even if the supply nozzle (1300) of the present invention is provided with a plurality of nozzle passages (1340), the extension direction of the injection passage (1342) can be set opposite to the extension direction of the intake passage (1341).

[0382] The first intake passage (1341a) and the first injection passage (1342a) may be arranged to overlap at least partly in the front-rear direction.

[0383] The above first intake path (1341a) may be provided longer than the above first injection path (1342a).

[0384] Accordingly, one end of the first intake passage (1341a) may be placed closer to the connecting pipe (1320) than the end of the first injection passage (1342a).

[0385] The above second intake path (1341b) can be arranged to overlap at least a portion of the above second injection path (1342b) in the forward and backward direction.

[0386] The above second intake path (1341b) may be provided longer than the above second injection path (1342b).

[0387] The end of the second intake passage (1341b) may be positioned closer to the connecting pipe (1320) than the end of the second injection passage (1341b).

[0388] The above second intake passage (1341b) may be arranged to overlap with the first injection passage (1341a) in the forward and backward direction, and may also be arranged to overlap with the first intake passage (1341a) in the forward and backward direction.

[0389] The end of the second intake passage (1341b) may be positioned closer to the connecting pipe (1320) than the end of the first injection passage (1341a).

[0390] The first injection path (1342a) and the second injection path (1342b) may be arranged between the first intake path (1341a) and the second intake path (1341b).

[0391] The first injection path (1342a) and the second injection path (1342b) can be arranged parallel to each other in the width direction inside the nozzle case (1310). As a result, regardless of the shape, arrangement, and length of the water intake path (1341), the first injection path (1342a) and the second injection path (1342b) can supply water intensively to the front area of ​​the evaporator (910) along the width direction of the circulation duct (820).

[0392] (The specific bulkhead / positional relationship between each euro is described in great detail in the preceding detailed description paragraph.)

[0393] Figure 14 illustrates a phenomenon that may occur in the supply nozzle provided in Figures 11 and 13.

[0394] Even if the water supplied from the above connecting pipe (1320) is sufficient in quantity and pressure to reach from one end to the other end of the injection passage (1342), a restricted area (P2) may be formed between the one end and the other end of the injection passage (1342) in which the injection amount is less than that of other areas.

[0395] Regardless of whether the above nozzle flow path (1340) is provided in a single unit or in a plurality of units, the restriction area (P2) can always be formed.

[0396] That is, the restricted area (P2) in which the injection amount is formed to be less than that of other areas may occur not only in the first injection path (1342a) arranged close to the connecting pipe (1320) but also in the second injection path (13242b) arranged far from the connecting pipe (1320). When the restricted area (P2) occurs, a problem may arise in which some areas of the evaporator (910) are not cleaned.

[0397] Figure 15 illustrates the concept of blocking the occurrence of a restricted area.

[0398] If the water supplied to the injection passage (1342) is sufficient to be transmitted from one end of the injection passage (1342) to the other end, the water colliding with the end of the injection passage (1342) or the bulkhead (1350) may return to the connecting pipe (1320) or generate reverse hydraulic pressure toward the connecting pipe (1320).

[0399] As a result, a stagnation area (S) in which water stagnates may be generated between one end and the other end of the injection passage (1342) due to a collision between water flowing in from the connecting pipe (1320) and water repelled from the end. When the stagnation area (S) is generated, the pressure or flow rate of water discharged to the injection unit (1330) is reduced, and therefore, a restriction area (P2) may be generated in the drainage area of ​​the injection unit (1330) corresponding to the stagnation area (S).

[0400] Referring to Fig. 15(a), the water returning to or providing pressure for returning to the injection passage (1342) from the end of the injection passage (1342) can be interpreted as the same situation as if an inlet passage (1341) is additionally arranged at the end of the injection passage (1342). In other words, it can be understood that the first flow rate (Q1) entering one end of the injection passage (1342) through the connecting pipe (1320) and the second flow rate (Q2) entering the end of the injection passage (1342) through the inlet passage (1341) from the connecting pipe (1320) create the stagnation area (S) in the center region of the injection passage (1342).

[0401] Referring to Fig. 15(b), when the quantity or water pressure of the second flow rate (Q2) is reduced, the first flow rate (Q1) can more strongly push the second flow rate (Q2) downstream of the injection passage (1342), thereby pushing the stagnation area (S) downstream of the injection passage (1342). Furthermore, when the second flow rate (Q2) is reduced below the critical region, the stagnation area (S) can be pushed out of the injection passage (1342) and into the region where the intake passage (1341) is formed.

[0402] As a result, the occurrence of the restricted area (P2) in the injection path (1342) can be prevented.

[0403] Referring to Fig. 15(c), the connecting pipe (1320) flowing into the water inlet channel (1341) can be blocked to prevent water from flowing into the water inlet channel (1341), and the water inlet channel (1341) can be designed so that only water that has passed through the injection channel (1342) flows into the water inlet channel (1341).

[0404] In this case, since the second flow rate (Q2) is extinguished, the first flow rate (Q1) can move to the end of the intake channel (1341), and a stagnant area (S) can be formed at the end of the intake channel (1341) due to water colliding at the end of the intake channel (1341). As a result, the stagnant area (S) can be prevented from being formed in the injection channel (1341) itself.

[0405] As a result, if the nozzle path (1340) is designed as in Fig. 15(C), the formation of the stagnant region (S) in the injection path (1342) can be fundamentally prevented.

[0406] In addition, since it may be inefficient and design-wise impossible to place an additional intake path (1341) at the end as well as the end of the injection path (1342), the supply nozzle (1300) of the present invention may design the nozzle path section (1340) as shown in Fig. 15(c).

[0407] In other words, the nozzle path (1340) provided in the supply nozzle (1300) of the garment treatment device of the present invention may further include an additional space (1343) that is additionally extended downstream of the injection path (1341) to form a space in which water that has passed through the injection path (1341) is collected.

[0408] The above additional space (1343) can form a space in which water introduced through the connecting pipe (1320) is stored after moving to the end of the injection path (1341).

[0409] As shown, the above additional space (1343) is partitioned by the injection path (1342) and a partition wall (1350), and the end of the injection path (1342) and one end of the above additional space (1343) may be provided to be in communication with each other.

[0410] Alternatively, the additional space (1343) may be provided to be additionally extended in a direction parallel to the injection path (1342) downstream of the injection path (1342).

[0411] Alternatively, the additional space (1343) may be provided to extend in a direction different from the extension direction of the injection path (1342) downstream of the injection path (1342).

[0412] The length of the above additional space (1343) may be provided to be the same as the length of the injection passage (1342), but may be provided to be smaller than the length of the injection passage (1342), or may be provided to be longer than the length of the injection passage (1342).

[0413] The diameter or width of the additional space (1343) may be provided to be the same as the diameter or width of the injection passage (1342), but the diameter or width of the injection passage (1342) may be provided to be smaller, and the diameter or width of the injection passage (1342) may be provided to be longer.

[0414] Since the water collected in the additional space (1343) cannot be discharged unless it moves back to the injection passage (1342), it may be advantageous for the additional space (1343) to be provided to be smaller than the length of the injection passage (1342) or smaller than the diameter or width of the injection passage (1342).

[0415] As a result, the additional space (1343) is designed to be connected only to the end of the injection passage (1342) and extend further downstream than the injection passage (1341), and as long as it can be designed to store water that has passed through the injection passage (1341), the additional space (1343) may be designed in any shape and structure.

[0416] The above additional space (1343) may be provided so that it is connected only to the end of the injection path (1341) and is blocked from connecting to other areas located upstream from the end of the injection path (1341).

[0417] Figure 16 illustrates another embodiment of the supply nozzle (1300) of the present invention to which additional space is applied.

[0418] The nozzle path (1340) of the supply nozzle (1300) of the present invention may further include an additional space (1343) that extends further downstream of the injection path (1342).

[0419] The above nozzle flow path (1340) may include only the injection flow path (1342) and the additional space (1343), and as shown, may further include an intake flow path (1341) in addition to the injection flow path (1342) and the additional space (1343).

[0420] The above injection path (1342) can be connected to the outside of the nozzle case (1310) through the injection unit (1330), but the additional space (1343) and the intake path (1341) can be provided so that the installation of the injection unit (1330) is excluded and thus communication with the outside of the nozzle case (1310) is impossible.

[0421] The above nozzle flow path (1340) may include an inlet flow path (1341) that receives and delivers water from a connecting pipe (1320), an injection flow path (1342) that injects water supplied from the inlet flow path (1341) into the inside of the circulation duct (820) or the evaporator (910), and an additional space (1343) that extends from the end of the injection flow path (1342) and provides a space for storing water that has passed through the injection flow path (1342).

[0422] The above-mentioned intake passage (1341) extends in the width direction from the above-mentioned connecting pipe (1320) and can transfer all of the water flowing into the above-mentioned connecting pipe (1320a) to one end of the above-mentioned injection passage (1342) to the above-mentioned injection passage (1342).

[0423] The above injection path (1342) can be arranged to overlap with the above intake path (1341) in the front-back direction. As a result, since both the injection path (1342) and the intake path (1341) are arranged, the length and area of ​​the nozzle case (1310) can be prevented from being excessively increased.

[0424] For example, the injection path (1342) may be arranged in front or behind the intake path (1341) and may be provided to communicate with the end of the intake path (1341).

[0425] The above injection path (1342) can be extended in the width direction and arranged parallel to the above intake path (1341).

[0426] The above-mentioned water inlet (1341) may further include an inlet connection for supplying water to one end of the above-mentioned injection outlet (1342).

[0427] The above injection path (1342) may include a spray unit (1330) that sprays water supplied from the connecting pipe (1320). The spray unit (1330) may be arranged along the extension direction of the injection path (1342).

[0428] The above injection path (1342) can be defined as an area from one end to the other end of the injection unit (1330), and the injection path (1342) can be distinguished from the intake path (1341) or the additional space (1343) based on the area where the injection unit (1330) is placed.

[0429] The above additional space (1343) may be placed downstream of the injection path (1342).

[0430] The above additional space (1343) may be provided to communicate with the end of the injection path (1342).

[0431] The above additional space (1343) may be provided in any shape as long as it can form a space in which water passing through the injection path (1342) can be stored.

[0432] However, in order to prevent excessive expansion of the nozzle case (1310), the additional space (1343) may be arranged to overlap the injection path (1341) in the front-back direction.

[0433] The above additional space (1343) may be provided as a channel that extends in the width direction parallel to the injection channel (1343) and has a closed end. This can prevent the length and area of ​​the nozzle case (1310) from increasing excessively.

[0434] For example, the additional space (1343) may be arranged in front or behind the injection passage (1342). In addition, the additional space (1343) may be extended in the width direction and arranged parallel to the injection passage (1342).

[0435] The above additional space (1343) may further include an additional bend connected to receive water from the end or downstream of the injection path (1342).

[0436] The above injection path (1342) may be arranged between the above intake path (1341) and the above additional space (1343). For example, if the above intake path (1341) is arranged at the rear of the injection path (1342), the above additional space (1343) may be arranged at the front of the injection path (1342).

[0437] Accordingly, the intake passage (1341), the injection passage (1342), and the additional space (1343) can be arranged without interfering with each other, and a passage can be formed in which water flowing into the nozzle passage (1340) flows in one direction without backflow or stagnation.

[0438] As a result, the end of the above-mentioned intake passage (1341) may be provided so as to be connected only to one end of the above-mentioned injection passage (1342). In addition, one end of the above-mentioned additional space (1343) may be provided so as to be connected only to the end of the above-mentioned injection passage (1342).

[0439] Meanwhile, the supply nozzle (1300) may further include a fastening member that fastens the nozzle case (1310) to the duct cover part (830) or, when one side of the nozzle case (1310) is opened, a cover that covers one side of the nozzle case (1310), and a fastening space (1344) provided in the nozzle case (1310) to provide a space in which the fastening member can be installed.

[0440] The above-mentioned coupling space (1344) is arranged adjacent to the intake passage (1341), the injection passage (1342), and the additional space (1343), and may be provided to extend in the width direction of the nozzle case (1310) so that a plurality of fastening members can be installed, and thus may be included in the nozzle passage portion (1340).

[0441] However, since the above-mentioned joining space (1344) is an area where a fastening member is installed, there is no need to introduce water into it. If water is introduced, not only will the water be wasted, but there is also a risk of corrosion of the fastening member. Therefore, the above-mentioned joining space (1344) may be provided to be completely separated from the above-mentioned water inlet (1341), the above-mentioned injection channel (1342), and the above-mentioned additional space (1343), and may be formed as a closed space without an inlet for water to flow into.

[0442] That is, the above-mentioned joining space (1344) may be provided with a space through which a fastening member such as a bolt or the like can pass, but may be provided so that water supplied from the connecting pipe (1320) is prevented from flowing into the interior.

[0443] The above-mentioned combination space (1344) can be arranged to overlap with at least one of the intake passage (1341), the injection passage (1342), and the additional space (1343) in the front-rear direction.

[0444] The garment treatment device of the present invention may include a partition wall (1350) provided inside the nozzle case (1310) to partition the nozzle passage (1340).

[0445] The above-mentioned partition walls (1350) may be provided in multiple numbers and spaced apart from each other to be arranged inside the nozzle case (1310) to form the intake passage (1341), the injection passage (1342), the additional space (1343), and the coupling space (1344).

[0446] The above partition wall (1350) may include a separation partition wall (1351) provided to completely separate the plurality of nozzle passages (1340) when the nozzle passages (1340) are arranged to be divided into a plurality of passages.

[0447] For example, when the nozzle flow path (1340) is provided with a first flow path (A) and a second flow path (B) independent of the first flow path, the separation partition (1351) can completely fluidically separate the first flow path (A) and the second flow path (B) inside the nozzle case (1340).

[0448] When the first flow path (A) and the second flow path (B) are arranged in the width direction, the separation partition (1351) can extend in the front-back direction between the inside of the nozzle case (1310) and both ends of the nozzle e-key (1310).

[0449] The above-mentioned partition wall (1350) is spaced apart from the back or front surface of the nozzle case (1310) to form the above-mentioned intake passage (1341), and may include an intake passage wall (1352) that separates the above-mentioned intake passage (1341) from at least one of the above-mentioned injection passage (1342), the above-mentioned additional space (1343), and the above-mentioned combination space (1344).

[0450] The above-mentioned intake bulkhead (1352) may be provided by extending from the inner surface of the connecting pipe (1320) or one end of the nozzle case (1310) to the inside of the nozzle case (1310).

[0451] The above-mentioned intake baffle (1352) is spaced apart from the back or front surface of the nozzle case (1310) and extends in the width direction or the length direction of the nozzle case (1310) to serve as a guide to guide water flowing in from the connection pipe (1320) to one end of the injection path (1342).

[0452] The above-mentioned intake bulkhead (1352) can block the intake passage (1341) from being fluidly connected to the injection passage (1342), the additional space (1343), and the coupling space (1344) from one end to the other.

[0453] The above-mentioned intake bulkhead (1352) can be placed between the above-mentioned intake path (1341), the above-mentioned injection path (1342), the above-mentioned storage space (1343), and the above-mentioned combination space (1344).

[0454] The above-mentioned intake bulkheads (1352) may be provided in multiple numbers and spaced apart from each other in parallel, so that the intake bulkheads (1352) themselves may form an intake passage (1341).

[0455] Alternatively, as illustrated, the inner surface of the nozzle case (1310) may be provided to form one side of the intake passage (1341), and the intake partition wall (1352) may be provided to form the other side of the intake passage (1341). In this case, the volume of the nozzle case (1310) can be prevented from becoming excessively large.

[0456] The length of the above-mentioned intake bulkhead (1351) may be provided to be shorter than the length of the above-mentioned intake passage (1341). As a result, the above-mentioned intake passage (1341) and the above-mentioned injection passage (1342) may be connected to each other through the end of the above-mentioned intake bulkhead (1351).

[0457] The above-mentioned partition wall (1350) may include a spray partition wall (1353) that extends inside the nozzle case (1310) and forms one side of the spray path (1341).

[0458] When the above-mentioned intake passage (1341) and the injection passage (1342) are sequentially arranged in the front-rear direction, the intake bulkhead (1352) may simultaneously perform the role of the injection passage (1353). That is, the intake bulkhead (1352) may be arranged between the intake passage (1341) and the injection passage (1342) to partition the intake passage (1341) and the injection passage (1342). In this case, one surface of the intake bulkhead (1352) may form the other surface of the intake passage (1341), and the other surface of the intake bulkhead (1352) may form one surface of the injection passage (1342).

[0459] However, when a storage space (1343) or a coupling space (1344) is arranged between the intake passage (1341) and the injection passage (1342), the injection partition wall (1353) may be arranged spaced apart from the intake passage wall (1352). The injection partition wall (1353) may be arranged spaced apart from both the rear surface and the front surface of the nozzle case (1310). In this case, the intake passage wall (1352) may form either one of the two surfaces of the intake passage (1341), and the injection partition wall (1353) may form either one of the injection passages (1353). The injection partition wall (1353) may be arranged parallel to the intake passage wall (1352).

[0460] The length of the above-mentioned injection baffle (1353) may be formed to be equal to or smaller than the length of the above-mentioned intake baffle (1352). As a result, a space can be secured through which water flowing in from the intake channel (1341) through the end of the above-mentioned injection baffle (1353) flows into the above-mentioned injection channel (1342).

[0461] The above-mentioned bulkhead (1350) may further include an additional bulkhead (1354) extending from inside the nozzle case (1310) to form the additional space (1343).

[0462] The above additional bulkhead (1354) can form either side of the above additional space (1343).

[0463] When the injection passage (1342) and the additional space (1343) are sequentially arranged in the front-rear direction, the additional partition wall (1354) may simultaneously perform the role of the injection passage wall (1353). That is, the additional partition wall (1354) may be arranged between the injection passage wall (1342) and the additional space (1343) to partition the injection passage wall (1342) and the additional space (1343). In this case, one surface of the additional partition wall (1354) may form the other surface of the injection passage wall (1342), and the other surface of the additional partition wall (1354) may form one surface of the additional space (1343).

[0464] However, when a storage space (1343) or a combination space (1344) is arranged between the injection passage (1342) and the additional space (1343), the additional partition wall (1354) may be arranged spaced apart from the injection partition wall (1353).

[0465] The additional bulkhead (1354) may be spaced apart from each other on both the back and front surfaces of the nozzle case (1310). In this case, the injection bulkhead (1353) may be provided in multiple numbers to form both surfaces of the multiple flow path (1342). The additional bulkhead (1354) may form either one of the two surfaces of the additional space (1354). The additional bulkhead (1354) may be arranged parallel to the injection bulkhead (1353) or the intake bulkhead (1352).

[0466] The length of the additional bulkhead (1354) may be formed to be equal to or smaller than the length of the injection bulkhead (1353). Alternatively, one end of the additional bulkhead (1354) may be spaced apart in the width direction from the end of the injection bulkhead (1353). As a result, a space may be secured through which water introduced from the injection path (1342) through the end of the additional bulkhead (1354) may be introduced into the additional space (1343).

[0467] Meanwhile, the additional partition wall (1354) may be provided in multiple pieces to form both sides of the additional space (1343). In this case, the additional space (1343) is provided independently of the injection partition wall (1353) and only communicates with the end of the injection path (1342), so the additional partition wall (1354) may be provided to extend in a direction different from the extension direction of the injection partition wall (1353).

[0468] Meanwhile, regardless of the shape in which the partition wall (1350) is provided, it may be provided to extend from the lower surface of the nozzle case (1310) to the upper surface of the nozzle case (1310) so as to completely partition the interior of the nozzle case (1310). The partition wall (1350) may be provided in the shape of a plate extending from the lower surface to the upper surface of the inner surface of the nozzle case (1310). As a result, water can be completely blocked from flowing over or passing through the partition wall (1350).

[0469] In summary, the entire embodiment of the nozzle path (1340) and the partition wall (1350) in the supply nozzle (1300) of the present invention, the supply nozzle (1300) of the garment treatment device of the present invention may be provided to necessarily include a connection pipe (1320) and an injection path (1343), and may be provided to further include at least one of the intake path (1341) and the additional space (1343). In addition, the supply nozzle (1300) of the garment treatment device of the present invention may further include the coupling space (1344).

[0470] For example, the nozzle case (1310) may be provided with the connection pipe (1320), the intake passage (1341), and the injection passage (1342). In this case, the turbulent region at one end of the injection passage (1342) is omitted or disappears, thereby preventing the formation of a deficiency region (P1) at one end of the injection passage (1342) or an adjacent area.

[0471] For example, the nozzle case (1310) may be provided with the connection pipe (1320), the injection path (1342), and the additional space (1343). In this case, the stagnation area (S) at the end of the injection path (1342) may be omitted or disappear, thereby preventing the formation of a restriction area (P2) at the end of the injection path (1342) or an area adjacent thereto.

[0472] For example, the nozzle case (1310) may be provided with the connection pipe (1320), the intake passage (1341), the injection passage (1342), and the additional space (1343). In this case, the stagnant region (S) and the turbulent region may disappear or be reduced in the entire area of ​​the injection passage (1342), so that neither the deficiency region (P1) nor the restriction region (P2) may be formed in the entire area of ​​the injection section (1330). Accordingly, the supply nozzle (1300) of the present invention can stably and uniformly supply water to the entire area.

[0473] As described above, the nozzle flow path (1340) of the present invention may include the first flow path (A) and the second flow path (B) separated from the first flow path (A) and spaced apart from the first flow path (A) in the width direction.

[0474] In this case, the connecting pipe (1320) may include a first connecting pipe (1320a) connected to the first supply pipe (1210), and a second connecting pipe (1320b) connected to the second supply pipe (1220) and spaced apart from the first connecting pipe (1320a). Both the first connecting pipe (1320a) and the second connecting pipe (1320b) may be provided to protrude from one end of the nozzle case (1310) toward the water collection unit (860) or away from the moving duct (822).

[0475] The above second connecting pipe (1320b) can be arranged to be spaced apart from the first connecting pipe (1320a) in the front-back direction but overlapped in the front-back direction.

[0476] For example, the first connecting pipe (1320a) may be placed at the rear of one side of the nozzle case (1310), and the second connecting pipe (1320b) may be placed at the front of one side of the nozzle case (1310).

[0477] The above water intake channel (1341) may include a first water intake channel (1341a) that is connected to the first connecting pipe (1320a) and supplies water, and a second water intake channel (1341b) that is connected to the second connecting pipe (1320a) and supplies water.

[0478] The first intake passage (1341a) can extend parallel to the extension direction of the first connecting pipe (1320a), and the second intake passage (1341b) can extend parallel to the extension direction of the second connecting pipe (1320b).

[0479] For example, the first connecting passage (1341a) may be arranged on the back surface of the nozzle case (1310), and the second connecting passage (1341b) may be arranged on the front surface of the nozzle case (1310).

[0480] The above second intake path (1341b) can be extended longer than the above first intake path (1341a).

[0481] For example, if the first intake passage (1341a) extends from one end of the nozzle case (1310) to the separation partition (1351), the second intake passage (1341b) may be arranged so that one end extends from one surface of the nozzle case (1310) and the other end faces the other surface of the nozzle case (1310). That is, the second intake passage (1314b) may extend in the width direction from the second connecting pipe (1320b) to beyond the separation partition (1351).

[0482] The above injection path (1343) may include a first injection path (1342a) that receives water from the first water intake path (1341a) and sprays water to the outside of the nozzle case (1310), and a second injection path (1342) that receives water from the second water intake path (1341b) and sprays water to the outside of the nozzle case (1310).

[0483] The first injection path (1342a) and the second injection path (1342b) may be arranged in parallel in the width direction. A separation bulkhead (1351) may be arranged between the first injection path (1342a) and the second injection path (1342b).

[0484] The above first injection path (1342a) may be positioned in front of the above first intake path (1341a).

[0485] The first injection flow path (1342a) may be provided to be equal to or smaller than the first intake flow path (1341a). That is, the first intake flow path (1341a) may be provided to have a sufficient length to prevent a shortage area (P1) from occurring in the first injection flow path (1342a).

[0486] The above second injection path (1342b) may be positioned further back than the above second intake path (1341b).

[0487] The second injection path (1342b) may be provided to be much smaller than the second intake path (1341b). That is, since the second intake path (1341b) is provided to be much longer than the second injection path (1342), the occurrence of a shortage area (P1) in the second injection path (1342b) can be prevented.

[0488] The above-mentioned joining area (1344) may include a first joining area (1344a) through which a fastening member may pass or be installed between the first intake passage (1341a) and the first injection passage (1342a), and a second joining area (1344b) disposed outside the second injection passage (1342b).

[0489] The first joining region (1344a) and the second joining region (1344b) can be arranged parallel to each other in the width direction. This prevents the worker from confusing the region where the fastening member is joined.

[0490] The first coupling area (1344a) and the second coupling area (1344b) can both be formed in a space separated from the inner surface of the nozzle case (1310). As a result, durability can be secured even if a fastening member penetrates the nozzle case (1310).

[0491] The above storage space (1343) may include a first storage space (1343a) that is connected only to the end of the first injection path (1342a) and a second storage space (1343b) that is connected only to the end of the second injection path (1342b).

[0492] The first injection path (1342a) and the first storage space (1343a) can be arranged in the front-back direction, and the second injection path (1342b) and the second storage space (1343b) can be arranged in the front-back direction.

[0493] For example, the first storage space (1343a) may be arranged in front of the first injection path (1342a). The first storage space (1343a) may be arranged between the first injection path (1342a) and the second intake path (1341b), and the end may be shielded by a separation partition (1351).

[0494] The second storage space (1342b) may be arranged in front of the second injection path (1342b). The second storage space (1343b) may be arranged between the second injection path (1342b) and the second intake path (1341b).

[0495] The first storage space (1343a) and the second storage space (1343b) may be arranged in parallel in the width direction and may be arranged separated by a separation partition (1351).

[0496] The above first flow path (A) includes the first connecting pipe (1320a) and the first injection flow path (1342a), and may further include the first intake flow path (1341a), the first storage space (1343a), and the first coupling space (1344a).

[0497] The above second flow path (B) includes the second connecting pipe (1320b) and the second injection flow path (1342b), and may further include the second intake flow path (1341b), the second storage space (1343b), and the second combination space (1344b).

[0498] The above separation bulkhead (1351) may extend from the back surface of the nozzle case (1310) toward the front surface, but may be spaced apart from the front surface of the nozzle case (1310) by a length corresponding to the diameter of the second inlet passage (1341b).

[0504] The above additional bulkhead (1354) may include a first additional bulkhead (1354a) that divides the first injection path (1342a) and the first additional space (1343a), and a second additional bulkhead (1354b) that divides the second injection path (1342b) and the second additional space (1343b).

[0505] The above first additional wall (1354a) may be provided to block water flowing through the first injection path (1342a) from flowing into the first additional space (1343a) except for the end of the first injection path (1342a).

[0506] The above first additional wall (1354a) can only allow water that has passed through the entire first injection path (1342a) to flow into the first additional space (1343a).

[0507] The above first additional price wall (1354a) can extend in the width direction from the separation partition (1351) toward one surface of the nozzle case (1310).

[0508] The length of the first additional wall (1354a) may be formed to be shorter than the lengths of the first injection passage (1342a) and the first additional space (1343a). As a result, the end of the first injection passage (1342a) and one end of the first additional space (1343a) may be connected.

[0509] The above first additional wall (1354a) can form the other side of the first injection path (1342a) and can form one side of the first additional space (1343a).

[0510] A part of the above second intake bulkhead (1352b) may form the other surface of the above first additional space (1343b).

[0511] The above first additional wall (1354a) may be provided to block water flowing through the first injection path (1342a) from flowing into the first additional space (1343a) except for the end of the first injection path (1342a).

[0516] The above second additional wall (1354b) may be provided to block water flowing through the second injection path (1342b) from flowing into the second additional space (1343b) except for the end of the second injection path (1342b).

[0517] The above second additional wall (1354b) can only allow water that has passed through the entire second injection path (1342b) to flow into the second additional space (1343b).

[0518] The second additional wall (1354b) may be bent at the end of the second intake wall (1352b) and then extended in the width direction toward one side of the nozzle case (1310) or the separation wall (1351).

[0519] The length of the second additional wall (1354b) may be formed to be shorter than the lengths of the second injection passage (1342b) and the second additional space (1343b).

As a result, the end of the second injection passage (1342b) and one end of the second additional space (1343b) may be connected.

[0524] The above second additional wall (1354b) can form the other side of the second injection path (1342b) and can form one side of the second additional space (1343b).

[0525] The remaining portion of the second intake bulkhead (1352b) may form the other surface of the second additional space (1343b).

[0526] Meanwhile, in all embodiments, the injection path (1342) may be defined as an area where the injection unit (1330) or injection hole (1333) is formed. The injection path (1342) may be defined as an area from one side to the other side of a plurality of injection holes (1333), and the outer sides of the injection holes (1333) may be defined as the intake path (1341) and the additional space (1343). Fig. 17 illustrates an embodiment of the injection unit of the present invention.

[0527] The injection unit (1330) of the present invention may include a first injection unit (1330a) formed in the first flow path (A) and a second injection unit (1330b) formed in the second flow path (B).

[0528] The first injection unit (1330a) may be provided to penetrate the lower surface of the nozzle case (1310) corresponding to the lower surface of the first injection path (1342a), and the second injection unit (1330b) may be provided to penetrate the lower surface of the nozzle case (1310) corresponding to the lower surface of the second injection path (1342b).

[0529] The first injection unit (1330a) and the second injection unit (1330b) may be arranged in parallel in the width direction. As a result, water may be supplied evenly in the width direction of the evaporator (910) and the moving duct (822), and the entire cross-section of the evaporator (910) and the moving duct (822) may be completely cleaned. For example, the entire front surface of the evaporator (910) may be cleaned.

[0530] Figure 18 illustrates an example structure of the above injection unit.

[0531] The above-mentioned injection unit (1330) may be provided so as to protrude downward from the injection path (1342). As a result, water can be discharged more intensively through the injection unit (1330) and supplied more accurately to a targeted location.

[0532] The above-mentioned injection unit (1330) may include an inclined surface (1331) extending downwardly from both sides of the injection path (1342). The inclined surface (1331) may serve to cause the injection unit (1330) to protrude downwardly from the nozzle case (1310).

[0533] The above injection unit (1330) may include an extension surface (1332) extending in the width direction from the lower portion of the inclined surface (1331), and an injection hole (1333) provided through the extension surface (1332).

[0534] The above injection holes (1333) may be provided in multiple numbers along the extension direction or width direction of the extension surface (1332).

[0535] The above injection holes (1333) may be provided in multiple numbers in the front-back direction.

[0536] The above extension surface (1332) can uniformly set the water pressure and quantity of water discharged through the entire injection hole (1333), and can secure a space in which multiple injection holes (1333) can be arranged in the front-back direction or width direction.

[0537] The nozzle case (1310) has a flat upper surface, so that the upper surface of the intake passage (1341), the upper surface of the additional space (1343), and the upper surface of the injection passage (1342) can be arranged parallel to each other.

[0538] However, the nozzle case (1310) may have lower surfaces having different heights. For example, the lower surface of the water inlet passage (1341) may be positioned at the lowest position. As a result, the amount of water flowing into the water inlet passage (1341) is sufficiently secured, thereby additionally forming water pressure to push water into the spray passage (1342). The lower surface of the additional space (1343) may be positioned at the highest position. As a result, the amount of water passing through the spray passage (1342) can be reduced, thereby minimizing water waste.

[0539] The lower surface of the above injection passage (1342) may be positioned between the lower surface of the above intake passage (1341) and the lower surface of the above additional space (1343). As a result, water collected in the above additional space (1343) may be naturally induced to flow back into the above injection passage (1342) and be discharged.

[0540] The lower surface of the above-mentioned joining space (1344) can be positioned corresponding to the lower surface of the above-mentioned additional space (1343). As a result, the area where the fastening member is positioned inside the above-mentioned fixing case (1310) can be minimized.

[0541] Fig. 19 illustrates an embodiment of preventing the scattering of water discharged from a spray hole.

[0542] When the above injection part (1330) protrudes downward from the nozzle case (1310), water can be discharged more intensively and at a stronger pressure through the injection hole (1333).

[0543] However, at least a portion of the water discharged from the injection hole (1333) may move along the outer surface of the injection unit (1330) due to surface tension or rise by flowing backwards along the inclined surface (1331).

[0544] In this case, not only is water not supplied accurately to the target point of the evaporator (910) and the moving duct (822), but the water is also supplied in a distributed manner over a wider area, which causes a problem in that the cleaning power of the evaporator (910) and the moving duct (822) is weakened.

[0545] To prevent this, the supply nozzle (1300) of the present invention may further include a separation unit (1360) that is arranged on the lower surface of the nozzle case (1310) to separate water.

[0546] The above separation unit (1360) may be a water-repellent agent applied to the outer lower surface of the injection unit (1330), or may be provided as a film of a water-repellent material or hydrophilic material attached to the outer lower surface of the injection unit (1330).

[0547] The above separation part (1360) may be arranged along the lower outer surface periphery of the injection hole (1333). That is, the outer surface of the injection hole (1333) may be provided to be in contact with the separation part (1360).

[0548] The above separation part (1360) can be arranged on the extension surface (1332) from the outer circumference of the injection hole (1333). As a result, the bonding force of the separation part (1360) arranged on the nozzle case (1310) can be increased.

[0549] In addition, the separating part (1360) may also be placed on the outer lower surface of the inclined surface (1331). This makes it possible to fundamentally block water sprayed from the spray hole (1333) from moving in an unintended direction along the surface of the extended surface (1332) and the inclined surface (1331).

[0550] The above separation part (1360) may include an inclined separation part (1361) applied or attached to the inclined surface (1331), and an extended separation part (1362) applied or attached to the extended surface (1332) but spaced apart from the injection hole (1333).

[0551] The above-mentioned slope separation unit (1361) and the above-mentioned extension separation unit (1362) may be provided as one unit or may be arranged to be connected to each other.

[0552] Figure 20 illustrates an additional embodiment of the above injection unit.

[0553] The above nozzle case (1310) may further include a partition surface (1334) formed by recessing from the lower outer surface to the upper surface between the first injection unit (1330a) and the second injection unit (1330b).

[0554] The above-mentioned partition surface (1334) can separate and partition the first injection part (1330a) and the second injection part (1330b) when the first injection part (1330a) and the second injection part (1330b) protrude into the first injection path (1342a) and the second injection path (1342b) of the nozzle case (1310), respectively.

[0555] Accordingly, the partition surface (1334) can form a mold placement point or injection point when the separation partition (1351) is molded inside the nozzle case (1310), and can induce the inside of the injected separation partition (1351) to be cooled evenly.

[0556] Additionally, the partition surface (1334) may block water discharged from one of the first injection unit (1330a) and the second injection unit (1330b) from moving to the other of the first injection unit (1330a) and the second injection unit (1330b).

[0557] The above-mentioned partition surface (1334) may extend inclinedly from the outer lower surface of the separation bulkhead (1351) toward the extension surface (1332), and the inclination of the partition surface (1334) may be provided to correspond to the inclination of the inclined surface (1331).

[0558] Figure 21 shows a cross-sectional view of the supply nozzle viewed from the front.

[0559] The above supply nozzle (1300) is provided with the injection part (1330) protruding downward.

[0560] The above nozzle case (1310) receives water from the connecting pipe (1320) at one end and delivers water to the end through the nozzle passage (1340).

[0561] The water supplied from the above connecting pipe (1320) first moves toward the injection unit (1330) by gravity. As a result, the water supplied from the connecting pipe (1320) can move along the first lower direction (L1) toward the end in a state close to the lower surface of the nozzle case (1310).

[0562] Water moving along the first low direction (L1) can be discharged through the injection unit (1330). Then, when the water is completely accumulated on the lower surface of the nozzle case (1310), the water can fill the water flowing in the first low direction (L1) while moving toward the end along the high direction (H) in a state where it gradually gets closer to the upper surface (1313) of the nozzle case (1310).

[0563] Meanwhile, water moving in the first low direction (L1) that is not discharged through the injection unit (1330) while moving to the end of the nozzle case (1310) may collide with the end of the nozzle case (1310) or the end of the nozzle passage (1340) and move again in the second low direction (L2) toward the connecting pipe (1320).

[0564] Additionally, water flowing in the high direction (H) that does not join the water flowing in the first low direction (L1) toward the end of the nozzle case (1310) can join the water in the second low direction (L2).

[0565] Water moving in the second low direction (L2) and water moving in the first low direction (L1) may collide. Meanwhile, water moving in the second low direction (L2) may have stronger water pressure and quantity than water moving in the first low direction (L1) because water flowing in the high direction (H) joins with it. This phenomenon may be further enhanced as the quantity and pressure of water flowing into the connecting pipe (1320) are stronger than the quantity and pressure of water discharged from the injection unit (1330). In addition, the flow rate of water flowing in the second low direction (L2) may be faster than the flow rate of water flowing in the first low direction (L1).

[0566] As a result, the water flowing in the second lower direction (L2) can be discharged to the injection unit (1330) at an angle toward the connecting pipe (1320). If the water is discharged at an angle from the injection unit (1330), there is a concern that water may not be smoothly supplied to at least one of the lower surface of the evaporator (910) or the moving duct (822) facing the injection unit (1330) or both sides of the moving duct (822) arranged adjacent to the injection unit (1330), and thus may not be washed.

[0567] This phenomenon can also occur in a situation where the above-mentioned intake channel (1341) and the above-mentioned injection channel (1342) are provided. Water can be discharged at an angle in an area further from the intake channel (1341) than in an area closer to the injection channel (1342).

[0568] Accordingly, the supply nozzle (1300) of the present invention can set the width or diameter of the nozzle path (1340) differently along the width direction so that water is sprayed in a vertical direction as much as possible throughout the entire area of ​​the spray section (1330).

[0569] For example, the cross-sectional area of ​​the injection path (1342) can be set differently along the extension direction of the injection path (1342).

[0570] Figure 22 illustrates an example in which the area of ​​the direct current flow path is variable.

[0571] The nozzle path (1340) of the supply nozzle (1300) of the present invention may have a cross-sectional area smaller than that of the injection path (1342) disposed farther from the connection pipe (1320) or the injection path disposed closer to the additional space (1342).

[0572] In other words, the cross-sectional area of ​​the injection path (1342) at one end may be set to be larger than the cross-sectional area at the other end. For example, the injection path (1342) may be provided so that the cross-sectional area becomes smaller from one end to the other end.

[0573] As a result, the water flowing in the injection passage (1342) encounters increasing resistance and becomes more difficult to move to the end, thereby reducing the flow rate or pressure of the second lower passage (L2). As a result, water can be evenly discharged in the vertical direction throughout the injection passage (1342).

[0574] Fig. 22(a) illustrates a direct flow path formed in a nozzle case (1310), Fig. 22(b) illustrates a cross-section of a nozzle flow path (1340) arranged adjacent to the connecting pipe (1320) in the first flow path (A), and Fig. 22(c) illustrates a cross-section of a nozzle flow path (1340) arranged adjacent to the end of the nozzle case (1310) in the first flow path (A).

[0575] The tendency for water to be discharged in a sloping manner may be more pronounced in the first flow path (A) where water is supplied in an area close to the connecting pipe (1320). However, at least some of the water may also be discharged in a sloping manner in the injection unit (1330) of the second flow path (B).

[0576] The following explanation is based on the first euro (A), but can also be applied to the second euro (B).

[0577] Referring to FIG. 22(b), the cross-sectional area of ​​the injection passage (1342) in the region near the end of the intake passage (1341) in the first passage (A) may be formed larger than the cross-sectional area of ​​the injection passage (1342) in the region near the separation partition (1351) in the first passage (A).

[0578] The overall height of the injection path (1342) in the above first path (A) can be formed to be the same.

[0579]

[0580] However, the width (D2) of the end of the injection passage (1342) may be set smaller than the width (D1) of one end. As a result, the cross-sectional area of ​​the end of the injection passage (1342) may be smaller than the cross-sectional area of ​​one end.

[0581] The above injection path (1342) may be designed to have a width that gradually narrows from one end to the other. As a result, water can be discharged vertically through the injection unit (1330) throughout the injection path (1342).

[0582] Figure 23 shows the flow rate of air moving through the circulation duct.

[0583] The above circulation duct (820) can form a path that sucks air from the drum (200) and supplies air to the drum (200) again.

[0584] The above circulation duct (820) may not be arranged parallel to the inlet (211) arranged on the front of the drum (200) and the suction hole (224) arranged on the back of the drum, but may be arranged offset to one side from the inlet (211) and the suction hole (224) of the drum (200).

[0585] For example, the circulation duct (820) may be arranged to be offset to one side in the width direction from the base (800). For example, one side (820a) of both sides of the circulation duct (820) may be arranged on the outer surface of the base (800), and the other side (820b) of both sides of the circulation duct (820) may be arranged close to the center of the base (800). The drum (200) is arranged in the front-back direction with the center of the base (800) as the center. As a result, the circulation duct (820) is arranged to be offset to one side in the direction of the air flow path inside the drum (200).

[0586] The above circulation fan (950) may be arranged in the discharge duct (823) to suck in air inside the circulation duct (820) and air inside the drum (200) at negative pressure. In this process, the air inside the drum (200) may be introduced into the inlet duct (821) and then pass through the movement duct (822), the discharge duct (823), and the circulation fan (950) to be re-introduced into the drum (200).

[0587] Since the air is sucked in while the circulation duct (820) is tilted to one side, and the circulation fan (950) is positioned tilted from the base (800) toward one side (820a) of the circulation duct, the air introduced into the inlet duct (821) is introduced in a more tilted state toward one side (820a) of the circulation duct. Therefore, the amount or velocity of air introduced into one side (820a) of the circulation duct through the inlet duct (821) may be greater than the amount or velocity of air introduced into the other side (820b) of the circulation duct. In addition, with the circulation duct (820) as a standard, the amount of air moving may gradually increase as it moves from the other side (820b) toward the one side (820a). As a result, the evaporator (910) and the moving duct (822) may accumulate more foreign substances in an area closer to the one surface (820a) than to the other surface (820b), and a larger amount of water may be required to wash them.

[0588] Figure 24 illustrates an additional embodiment of a supply nozzle.

[0589] The above supply nozzle (1300) may be provided so as to be able to spray a larger amount of water to either one end or the other end of the nozzle case (1310).

[0590] The above supply nozzle (1300) may be provided to spray a greater amount of water into an area adjacent to one side (820a) of the circulation duct within the evaporator (910) and the moving duct (822) than into an area adjacent to the other side (820b). Accordingly, even if more foreign substances accumulate in an area closer to one side within the evaporator (910) and the circulation duct (820), they can be sufficiently washed away.

[0591] To this end, the injection path (1342) may be formed to inject a greater amount of water on one end facing one side (820a) of the two sides of the circulation duct (820) than on the other end facing the other side (820b).

[0592] Specifically, the number per unit area of ​​the injection holes (1333) arranged closer to the one side (820a) in the injection path (1342) may be formed to be greater than the number per unit area of ​​the injection holes arranged closer to the other side (820b). As a result, the supply nozzle (1300) can supply water with a more concentrated and stronger pressure to an area where foreign substances are presumed to have accumulated more, thereby cleaning the area.

[0593] In the case where the above nozzle flow path (1340) is provided in multiple numbers, the second injection flow path (1342b) may be arranged closer to one side of the circulation duct (820) than the first injection flow path (1342a), and the second injection flow path (1342b) may be provided to discharge a larger amount of water than the first injection flow path (1342a).

[0594] The length of the second injection passage (1342b) may be formed to be equal to or shorter than the length of the first injection passage (1342a). The number of injection holes (1333) installed in the second injection passage (1342b) may be equal to or greater than the number of injection holes (1333) installed in the first injection passage (1342a). As a result, if the amount and water pressure of water supplied from the first connection pipe (1320a) and the second connection pipe (1320b) are the same, the pressure or water quantity of water sprayed from the second injection passage (1342b) may be increased.

[0595] Figure 25 illustrates another embodiment of a supply nozzle.

[0596] The diameter of the injection hole (1333) positioned close to one side (820a) of the circulation duct in the injection path (1341) may be provided to be much larger than the diameter of the injection hole positioned close to the other side (820b).

[0597] In the case where the above nozzle flow path (1340) is provided in multiple numbers, the diameter of the second injection hole (1333b) may be provided to be larger than the diameter of the first injection hole (1333a).

[0598] Therefore, regardless of the length of the first injection path (1342a) and the second injection path (1342b), the second injection path (1342b) can supply a larger amount of water per unit area than the first injection path (1342a).

[0599] Figure 26 illustrates an additional embodiment in which the supply nozzle is installed in a circulation duct.

[0600] The above supply nozzle (1300) may be positioned closer to the upper surface than the bottom surface of the circulation duct (820). Accordingly, the supply nozzle (1300) may be positioned higher than the evaporator (910) so as to wash the entire area of ​​the evaporator (910) from top to bottom.

[0601] However, the supply nozzle (1300) may be fixed by being joined to the lower surface, rather than the upper surface, of the duct cover part (830). As a result, the duct cover part (830) may be omitted from having a separate through-hole for discharging water from the supply nozzle (1300). As a result, air passing through the circulation duct (820) can be prevented from leaking, thereby increasing drying efficiency and preventing the interior of the cabinet (100) from being corroded or damaged by moisture.

[0602] The above nozzle case (1310) may be installed in an area that shields the upper portion of the moving duct (822) in the duct cover part (830). The width of the nozzle case (1310) may be provided to be equal to or slightly smaller than the width of the moving duct (822).

[0603] In the above nozzle case (1310), the first connecting pipe (1320a) and the second connecting pipe (1320b) may be provided in a protruding manner on one side or a side close to the other side (820b) of the circulation duct.

[0604] The first connecting pipe (1320a) and the second connecting pipe (1320b) can be formed integrally with the nozzle case (1310).

[0605] The above supply pipe (1200) may be connected to the first supply pipe (1210) and the second supply pipe (1220) may be connected to the second connection pipe (1320b). During the connecting process, known connecting members such as sealers and bosses may be added.

[0606] The above supply nozzle (1300) can be coupled to the duct cover part (830) by the fastening member (1360) penetrating the lower part of the nozzle case (1310). The fastening member (1360) can be coupled by penetrating the duct cover part (830) or can be coupled by being received on the lower surface of the duct cover part (830).

[0607] The above fastening member (1360) can be connected by penetrating the above joining area (1344).

[0608] The above fastening member (1360) may be provided in multiple pieces and arranged spaced apart from each other along the direction in which the joining area (1344) extends. As a result, the nozzle case (1310) may be firmly fixed to the duct cover part (830) from one end to the other.

[0609] Fig. 27 illustrates an example of the structure of a coupling space in a supply nozzle.

[0610] Referring to Fig. 27(a), a joining space (1344) into which the fastening member is joined may be arranged inside the nozzle case (1310). The nozzle case (1310) may be provided with a joining hole (1345) through which the fastening member (1360) may pass in the joining space (1344). The joining hole (1345) may be provided to pass through the lower surface of the nozzle case (1310).

[0611] The above supply nozzle (1300) may further include a support member (1370) that protrudes from at least one of both sides of the coupling hole (1345) and guides the fastening member (1360). The support member (1370) may be manufactured integrally with the nozzle case (1310) and may be formed to protrude upward from the lower inner surface of the nozzle case (1310).

[0612] The above support member (1370) can guide the free end of the above fastening member (1360) to the nozzle cover (1313) when the above fastening member (1360) is inserted, and the inside of the nozzle case (1310) can be prevented from being damaged by the above fastening member.

[0613] The above support member (1370) may be provided in the shape of a pipe arranged along the circumference of the above coupling hole (1345), or may be arranged on both sides of the above coupling hole (1345) at a distance equal to the diameter of the above coupling hole (1345).

[0614] If the above fastening member (1360) is provided as a bolt or the like having a screw thread on the outer surface, the support member (1370) may have a screw thread or gear tooth formed on the inner surface facing the coupling hole (1345) that can engage with the fastening member (1360).

[0615] Referring to Fig. 27(b), the fastening member (1360) can be inserted into the joining hole (1345) and joined to the nozzle cover (1313) while being supported by the support member (1370).

[0616] In the case where the above supply nozzle (1300) further includes a separate sealing member (1312) between the nozzle case (1310) and the nozzle cover (1313), the fastening member (1360) can penetrate the sealing member (1312) and be coupled to the nozzle cover (1313).

[0617] The above support member (1370) can also serve to block or minimize the exposure of the fastening member (1360) to the inside of the nozzle case (1310). As a result, the fastening member (1360) can be prevented from being corroded by moisture or humidity remaining inside the nozzle case (1310).

[0618] Figure 28 illustrates the detailed structure of the above supply nozzle.

[0619] The above nozzle case (1310) may include a nozzle body (1311) that forms a space in which the connecting pipe (1320) is extended and a nozzle passage (1340) is formed inside.

[0620] The above nozzle body (1311) may be provided in a case shape.

[0621] The above nozzle body (1311) can be formed with an open upper surface. Accordingly, even if a complex nozzle flow path (1340) and a partition wall (1350) are formed inside the nozzle body (1311), the nozzle body (1311) can be manufactured simultaneously by a method such as injection molding.

[0622] Meanwhile, the nozzle case (1310) may further include a nozzle cover (1313) that shields the upper portion of the nozzle body (1311). The nozzle cover (1313) can shield the upper portion of the nozzle body (1311) to prevent water flowing into the nozzle body (1311) from leaking out.

[0623] The above nozzle cover (1313) may be provided in a case shape that is larger than the area of ​​the nozzle body (1311) and can accommodate at least a portion of the nozzle body (1311). Accordingly, the outer surface of the nozzle body (1311) and the inner surface of the nozzle cover (1313) can be detachably connected through a connecting member such as a hook.

[0624] Meanwhile, the nozzle case (1310) may further include a sealing member (1312) that is placed between the nozzle body (1311) and the nozzle cover (1313) to seal the upper surface of the nozzle body (1311).

[0625] The sealing member (1312) may be made of an elastic material and may be pressurized and provided on the nozzle case (1310) and the nozzle cover (1313). The sealing member (1312) may be provided in a plate shape corresponding to the area of ​​the upper surface of the nozzle body (1311).

[0626] The above sealing member (1312) may be provided so as to be in contact with and pressurized by the entire upper surface of the partition wall (1350). Specifically, the nozzle body (1311) and the nozzle cover (1313) may be provided so as to pressurize the sealing member (1312) through a hook connection.

[0627] The above nozzle body (1311) may be provided with a hook (1390) protruding from the outer surface of the nozzle case (1310), and the nozzle cover (1313) may be provided with a hook groove (1380) to which the hook (1390) is detachably coupled.

[0628] The above hook (1390) may be provided along the circumference of the nozzle case (1310), and the hook groove (1380) may be positioned corresponding to the hook (1390).

[0629] In this way, the bonding force between the nozzle body (1311) and the nozzle cover (1313) can be made uniform along the perimeter of the nozzle case (1310), and at the same time, the pressure applied to the sealing member (1312) can also be made uniform.

[0630] As a result, even if the entire upper surface of the partition wall (1350) is not in close contact with the nozzle cover (1313) due to tolerances or the like, the sealing member (1312) can close the entire upper surface of the partition wall (1350). As a result, water or air can be fundamentally blocked from passing through the upper surface of the partition wall (1350).

[0631] The above-mentioned partition wall (1350) may be provided to extend upward from the lower inner surface of the nozzle body (1311). The partition wall (1350) may be formed integrally with the nozzle body (1311). As a result, water contained in the nozzle passage (1340) may be prevented from arbitrarily flowing to another area through the partition wall (1350) and the sealing member (1312).

[0632] Figure 29 illustrates an additional embodiment of the washing unit of the present invention.

[0633] The washing unit (1000) of the present invention may be equipped to wash the inside of the circulation duct (820) or the evaporator (910) with water collected in the water collection unit (860) rather than an external water source.

[0634] The clothing treatment device of the present invention may be equipped to collect water condensed in a circulation duct (820) or water remaining in the circulation duct (820) into a water collection unit (860), and supply the water collected in the water collection unit (860) to the supply nozzle (1300) as needed.

[0635] In the present embodiment, the supply nozzle (1300) may be installed in the duct cover part (830) and may be positioned above the evaporator (910). The supply nozzle (1300) may be coupled to the lower surface of the duct cover part (830) and may be positioned and secured on the upper surface of the duct cover part (830).

[0636] The washing unit (1000) of the present invention may include a switching valve (870) that can supply water collected in the water collection unit (860) to the supply nozzle (1300), and a guide pipe (1200) that guides water supplied from the water collection unit (860) to the supply nozzle (1300) from the switching valve (870).

[0637] The above switching valve (870) may be coupled to the duct cover (830) or the moving duct (822) and connected to the drain pipe (864) to receive water from the pump (861).

[0638] The clothing treatment device of the present invention may further include a discharge pipe (866) that is connected to the switching valve (870) and a water tank or a sewer pipe to discharge water collected in the water collection unit (860) to the outside of the base (800).

[0639] The above switching valve (870) may be provided so as to be connected to all of the drain pipe (864), the discharge pipe (866), and the guide pipe (1200). The switching valve (870) may be provided as a three-way valve or the like, so as to selectively supply water supplied from the drain pipe (864) to the discharge pipe (866) and the guide pipe (1200).

[0640] The above switching valve (870) may be provided to connect the drain pipe (864) and the discharge pipe (866), or to connect the drain pipe (864) and the guide pipe (1200). When the switching valve (870) is controlled to connect the drain pipe (864) and the guide pipe (1200), and the pump (861) is driven, water collected in the water collection unit (860) can be supplied to the supply nozzle (1300). As a result, the inside of the circulation duct (820) and the evaporator (910) can be cleaned.

[0641] The above switching valve (870) is controlled to connect the drain pipe (864) and the discharge pipe (866), and when the pump (861) is driven, the washed foreign substances can be removed to the outside of the base (800).

[0642] The above supply nozzle (1300) may be provided with the same structure as at least one of the above-described embodiments. As a result, water can be stably and evenly sprayed across the entire area from one end to the other end of the spray section (1330) of the supply nozzle (1300).

[0643] The present invention may be implemented in various modified forms, and its scope is not limited to the above-described embodiments. Therefore, if a modified embodiment includes elements of the claims of the present invention, it should be considered to fall within the scope of the present invention.
