Description

Clothing processing device and control method of clothing processing device

[0001] The present invention relates to a garment processing device and a control method thereof. More specifically, it relates to a washing machine capable of performing both a washing process of washing clothes using detergent and water and a drying process of drying moisture from clothes by supplying hot air.

[0002]

[0003] Generally, a clothing processing device includes a washing machine that removes foreign substances from clothing using water and detergent, and a dryer that dries the moisture contained in the clothing using hot air.

[0004] Recently, a garment processing device has emerged that combines the functions of a washing machine and a dryer into a single unit. This garment processing device includes a drum for receiving clothes and a tub for receiving the drum; a drainage section for draining water from the tub is positioned at the bottom of the tub, and a circulation duct for circulating air inside the tub and the drum is positioned at the top of the tub. In this conventional garment processing device, a heat exchanger for heat exchange of the air is placed inside the circulation duct, and a compressor is placed outside the tub.

[0005] Recently, a garment processing device has appeared in which the compressor is positioned below the tub, and a heat exchanger positioned above the tub is connected to the compressor via the refrigerant pipe. (See CN116200902A, CN116200923A)

[0006] By securing additional space in the upper region of the tub where the compressor was installed, this garment processing device was able to not only increase the width of the circulation duct but also arrange the circulation duct in the front-rear direction. Accordingly, there was an advantage of increased drying efficiency.

[0007] However, in conventional clothing processing devices, the refrigerant pipe (950) connecting the compressor located at the bottom of the tub and the heat exchanger placed inside the circulation duct is supported on the tub, etc., and there was a problem in that the refrigerant pipe (950) was directly exposed to the vibration of the tub.

[0008] In addition, when the refrigerant pipe (950) is positioned at the rear of the tub, etc., the refrigerant pipe (950) is formed to be frequently bent in correspondence with the rear shape of the tub, which not only increases the flow resistance of the refrigerant but also causes a problem of heat loss as the refrigerant pipe (950) becomes longer.

[0009] Furthermore, since the aforementioned conventional garment processing device is equipped to dry the washed clothes immediately as a combined washing machine and dryer, there is no opportunity for the user to separately remove foreign substances adhering to the surface of the clothes; consequently, there was a problem in which more foreign substances accumulated on the heat exchanger placed inside the circulation duct. However, because the user had no choice but to manually remove such foreign substances, the conventional garment processing device had a fundamental problem in that the drying performance of the device could not be guaranteed without user intervention.

[0010] Even if we assume that a nozzle structure for washing a heat exchanger with clean water supplied from a water supply valve is applied to such a conventional clothing processing device, as long as the circulation duct is positioned at the top of the tub, it may be difficult to secure space to install the nozzle structure above the circulation duct.

[0011] In addition, there was a fundamental problem in that conventional clothing processing devices did not provide any indication or possibility regarding how to install the nozzle structure in a circulation duct positioned above the tub.

[0012]

[0013] The present invention aims to solve the problem of providing a clothing processing device capable of cleaning a heat exchanger in a washing machine combined with a dryer using water supplied from a water supply valve.

[0014] The present invention aims to solve the problem of providing a clothing processing device that secures a structure capable of installing a nozzle part capable of cleaning a heat exchanger inside a circulation duct.

[0109] Hereinafter, embodiments disclosed in this specification will be described in detail with reference to the attached drawings. In this specification, identical or similar reference numbers are assigned to identical or similar components even if they are different embodiments, and the description thereof is replaced by the first description. Singular expressions used in this specification include plural expressions unless the context clearly indicates otherwise.

[0110] FIG. 1 illustrates the clothing processing device of the present invention.

[0111] The clothing processing device of the present invention may include a cabinet (100) forming an exterior and a clothing receiving section (200) provided to store clothing inside the cabinet (100).

[0112] The clothing receiving section (200) may include a drum (220) for storing clothing inside the cabinet (100). The drum (220) may be provided to rotate the clothing inside the cabinet (100).

[0113] Alternatively, the clothing receiving section (200) may further include a tub (210) for storing water inside the cabinet (100), and the drum (220) may be rotatably provided inside the tub (210).

[0114] The cabinet (100) may include a front panel (110) having an opening (111) communicating with the interior of the drum (220), side panels (150) arranged on both sides of the front panel (110), and a back panel (160) connecting the back of the side panels (150).

[0115] The above front panel (110) may be provided in a plate shape, and a door (112) for opening and closing the opening may be rotatably coupled.

[0116] The above front panel (110) may be equipped with an interface (I) that receives user commands or displays the status of the clothing processing device above the opening (111). At least a portion of the interface (I) may be provided as a touch panel.

[0117] The cabinet (100) may further include an installation panel (120) that is positioned above the opening of the drum (220) and coupled to side panels (150) positioned on both sides.

[0118] The above installation panel (120) may be equipped with a control panel capable of receiving commands to control the clothing processing device or displaying the operating status of the clothing processing device to the outside.

[0119] The above installation panel (120) can be positioned at the rear of the above front panel (110) (110) and can be coupled to the upper part of the front of the above side panel (150).

[0120] The above-described installation panel (120) may have a panel installation part (121) formed therein for fixing the front of the circulation duct (800) described later. The panel installation part (121) may be provided in a groove shape for mounting the rear of the circulation duct (800), or in a hole shape through which a fastening member, which is fastened to the rear of the circulation duct (800), passes.

[0121] The tub (210) may be provided in a cylindrical shape and may be provided with an inlet (213) at the front for introducing clothing. The inlet (213) may be provided to communicate with the opening of the front panel (110) and may also be provided to communicate with the inside of the drum (220).

[0122] The drum (220) may be provided with a cylindrical metal material with an open front, and may have a through hole on its outer surface so that water and detergent stored in the tub (210) can be introduced or discharged.

[0123] The clothing processing device of the present invention may further include a water supply and drainage unit (400) for supplying or draining water to the tub (200).

[0124] The above water supply and drainage unit (400) may include a water supply unit (410) that supplies water to the tub (210) and a drainage unit (420) that drains the water contained in the tub (210) to the outside of the cabinet (100).

[0125] The above water supply unit (410) may include a water supply valve (411) that receives water from an external water source, a water supply pipe (413) that guides the water supplied from the water supply valve (411) toward the tub (200), and a detergent box (412) that stores detergent and receives water supplied from the water supply valve (411) to supply the detergent to the tub (200).

[0126] The above water supply valve (411) can be connected to the back panel (160) and, if necessary, may be provided in multiple numbers to selectively open and supply water. The above water supply pipe (413) may also be provided in multiple numbers to supply water to at least one of the detergent box (411), the tub (210), and the circulation duct (800) described later.

[0127] The above drainage section (420) may include a drain pipe (421) extending from the lower part of the tub (210) and a drain pump (422) that provides power to discharge water discharged from the drain pipe (421) to the outside of the cabinet (100).

[0128] Additionally, the above-mentioned water supply and drainage unit (400) may further include a circulation unit (430) that recirculates water drained from the drain pipe (421) back into the tub (210).

[0129] The above circulation unit (430) may include a circulation nozzle (431) coupled to the inlet (213) of the tub to discharge water into the tub (200), and at least one of a circulation hose and a circulation pump that supply water discharged from the drain pipe (421) to the circulation nozzle (431).

[0130] The present invention may further include a base (600) forming the bottom surface of the clothing processing device. The base (600) may be provided to support the cabinet (100) on which the cabinet (100) is seated. Additionally, the base (600) may support electrical components such as the drainage pump (421).

[0131] The clothing processing device of the present invention may further include a support member (500) that supports the tub (200) inside the cabinet (100). The support member (500) may be provided with a plurality of suspensions, one end of which is connected to the tub (200) and the other end of which is connected to the base (600).

[0132] The garment processing device of the present invention may further include a circulation duct (800) capable of circulating air inside the tub (210). The circulation duct (800) may form a flow path for circulating air inside the drum (220) outside the tub (210). Thus, the garment processing device of the present invention may be equipped as a washing machine with a drying function.

[0133] Since components such as a drainage section (420) and a support section (500) are arranged in the lower part of the tub (210), the circulation duct (800) can be placed above the tub (210).

[0134] The clothing processing device of the present invention may further include a heat exchanger (900) for heating air moving through the circulation duct (800). The heat exchanger (900) may include a heat exchanger disposed inside the circulation duct (800) and a compressor (940) disposed outside the circulation duct (800) for supplying high-temperature refrigerant to the heat exchanger.

[0135] The compressor (940) may be positioned below the tub (210). Therefore, a wider space may be secured between the upper part of the tub (210) and the side panel (150) for installing the circulation duct (800). Accordingly, in the clothing processing device of the present invention, the circulation duct (800) may be extended and arranged in the front-rear direction. As a result, the circulation duct (800) extends in the same direction as the extension of the tub (210) and the drum (220), thereby reducing flow resistance and allowing hot air to be supplied evenly inside the drum (220).

[0136] Additionally, by omitting the compressor (940) above the tub (210), the circulation duct (800) can be positioned offset toward either of the two side panels (150) from the top of the tub (210), thereby expanding the cross-sectional area of ​​the circulation duct (800). Accordingly, the clothing processing device of the present invention can circulate a larger flow rate of air to the outside of the tub (210) than when the compressor (940) is positioned above the tub (210).

[0137] The clothing processing device of the present invention may further include a circulation fan (1000) mounted in a circulation duct (800) to circulate air in the tub (210). Since the compressor (940) is not positioned at the top of the tub (210), the circulation fan (1000) may be positioned at the rear of the circulation duct (800) to suck in air from inside the tub (210) and supply it into the circulation duct (800).

[0138] Additionally, since the compressor (940) is positioned below the tub (210), the circulation fan (1000) can utilize the entire space between the top of the tub (210) and the side panel (150). As a result, the circulation fan (1000) can be positioned with a diameter in the width direction and arranged to rotate around a vertical axis of rotation, thereby enabling the circulation of a more abundant flow rate.

[0139] As a result, in the clothing processing device of the present invention, the compressor (940) is positioned lower than the tub (210), so that a larger flow rate per unit time can circulate through the circulation duct (800), thereby increasing the drying efficiency.

[0140] Figure 2 illustrates the arrangement of the circulation duct and the heat exchanger.

[0141] The tub (210) is provided in a cylindrical shape extending in the front-rear direction, and the cabinet (100) is provided in an internal rectangular shape. Accordingly, in the upper region of the tub (210), more space is secured to the left and right of the center (O) in the width direction of the cabinet (100).

[0142] The above circulation duct (800) may be positioned offset from the center (O) in either the left or right direction. That is, the width-direction center of the above circulation duct (800) may also be positioned offset from the width-direction center (O) of the cabinet in either the left or right direction.

[0143] At this time, a portion of the circulation duct (800) may be arranged to overlap the width-direction center (O) and the height-direction of the cabinet. Additionally, a portion of the circulation duct (800) may be arranged spaced apart from the width-direction center (O) of the cabinet in either the left or right direction. As a result, the cross-sectional area of ​​the circulation duct (800) may be expanded.

[0144] Meanwhile, the compressor (940) may be positioned so as to be offset from the left or right side of the width direction center (O) of the cabinet (100) where the circulation duct (800) is offset.

[0145] For example, the compressor (940) may be placed at the bottom of the circulation duct (800), and the circulation duct (800) and the compressor (940) may be placed so that at least a portion overlaps in the height direction.

[0146] As a result, the vertical distance between the circulation duct (800) and the compressor (940) can be reduced, and the length of the refrigerant pipe (950) connecting the compressor (940) and the heat exchanger placed inside the circulation duct (800) can be reduced. Accordingly, the refrigerant pipe (950) can be arranged in a straight line in the maximum height direction, thereby reducing the flow resistance of the refrigerant and minimizing heat loss occurring in the refrigerant pipe (950).

[0147] Meanwhile, the heat exchanger (900) of the present invention may further include a fixing plate (960) for fixing the refrigerant pipe (950) to the back panel (160) of the cabinet (100). The fixing plate (960) may be provided in the shape of a bracket in which the height is greater than the width, and at least one of the back and both sides of the refrigerant pipe (950) is mounted. Thus, the refrigerant pipe (950) can be spaced apart from the tub (210) and supported by the fixing plate (850) and the cabinet (100), and vibrations generated in the tub (210) are prevented from being directly transmitted to the refrigerant pipe (950), thereby enhancing durability.

[0148] Consequently, the compressor (940), the circulation duct (800), the refrigerant pipe (950), and the fixing plate (960) can all be positioned on the left side of the tub (210) or on the right side of the tub (210). Thus, the compressor (940), the circulation duct (800), the refrigerant pipe (950), and the fixing plate (960) can all be easily installed, repaired, and replaced when a single side panel (150) is removed.

[0149] The above circulation duct (800) may include a duct body (810) on which the heat exchanger is seated, and a duct cover (820) coupled to the duct body (810) to shield the duct body (810).

[0150] The above duct body (810) may be provided in a case shape or duct shape with an open top, and the above duct cover (820) may be provided in a plate shape or case shape corresponding to the shape of the duct body (810).

[0151] The above duct body (810) may include a rear connecting part (850) connected to the rear of the tub (210) and communicating with the tub (210), and a front connecting part (840) connected to the front of the tub (210) and communicating with the tub (210).

[0152] The rear connecting part (850) and the front connecting part (840) may be provided in the shape of a duct or pipe through which air can move. The rear connecting part (850) and the front connecting part (840) may be provided with an elastic material. Thus, even if the tub (210) vibrates, the vibration of the tub (210) can be prevented from being transmitted to the duct body (810).

[0153] The above circulation duct (800) may be connected to the tub (210) only at the front connection part (840) and the rear connection part (850), and the duct body (810) may be spaced apart from the tub (210). It may further include a bracket (830) that fixes the position of the rear connection part (850) by fixing the rear connection part (850) to the tub (210).

[0154] The bracket (830) can be positioned at the bottom of the duct body (810) and seated on the tub (210). Thus, even if the duct body (810) is positioned to block the air inlet / outlet of the tub (210), the position of the rear connecting part (850) is fixed through the bracket (830), allowing the air inlet / outlet of the tub (210) and the duct body (810) to be easily connected via the rear connecting part (850).

[0155] FIG. 3 illustrates the structure of the base and the back panel.

[0156] The above base (600) may include a base body (610) that supports the load of the clothing processing device and an installation groove (620) that is recessed in at least one of the left and right sides of the base body (610).

[0157] The above installation groove (620) may be positioned offset to one side of the base body (610) and may be positioned at the rear of the base body (610). The above installation groove (620) may form a space on which the compressor (940) is seated.

[0158] The clothing processing device of the present invention may further include a control unit or a control panel (2000) capable of controlling electrical components placed in the clothing processing device. A circulation duct (800) may be installed on one side of the upper part of the tub (210), and a detergent box or a water storage tank, etc., may be installed on the other side. Accordingly, the control panel (2000) may be installed on the base body (610) and positioned below the tub (210).

[0159] The control panel (2000) may be positioned on the base body (610) spaced apart from the installation groove (620). For example, the control panel (2000) may be positioned offset to the other side of the base body (610). As a result, the control panel (2000) may be prevented from being exposed to heat generated by the compressor (940). Additionally, by positioning the control panel (2000) and the compressor (940) on both lower sides of the tub (210), interference between the control panel (2000) and the compressor (940) and the tub (210) may be prevented.

[0160] The control panel (2000) may include an HP case (2100) that controls the heat exchanger (900) and a main PCB (2200) coupled to the HP case (2100) to control electrical components other than the heat exchanger (900). Since the HP case (2100) has a larger volume and generates more heat than the main PCB (2200), the control panel (2000) may include a panel fan (2300) coupled to one side of the HP case (2100) to cool the HP case (2100). Additionally, the control panel (2000) may further include a noise filter (2300) capable of removing noise from various sensors of the clothing processing device, current supplied from external power, or electrical signals generated from the HP case (2100) and the main PCB (2200). The noise filter (2300) may be mounted on the upper part of the main PCB (2200) to receive current or transmit a current signal.

[0161] The above rear panel (160) may be provided with a panel fixing part (161) on the upper part for fixing the rear of the circulation duct (800). The panel fixing part (161) may be provided in a groove shape for mounting the rear of the circulation duct (800), or in a hole shape through which a fastening member that is fastened to the rear of the circulation duct (800) passes.

[0162] Figure 4 illustrates the structure of the above tub.

[0163] The above tub (210) may include a cylindrical tub body (211) and an inlet (214) provided at the front of the tub body (211) into which clothing can be inserted.

[0164] The diameter of the inlet (214) may be smaller than the diameter of the tub body (211). The circulation part (430) may be coupled to and fixed to the outer surface of the inlet (214).

[0165] The above tub body (211) may be formed by dividing it into a front body and a rear body and joining them together, or it may be formed as a single unit.

[0166] The above tub (210) may further include an air outlet (212) provided at the upper rear of the tub body (211) through which air inside the tub (210) is discharged, and an air inlet (213) provided at the upper part of the inlet (214) through which air discharged from the circulation duct (800) is introduced.

[0167] The air outlet (212) may be formed offset to one side from the top of the tub body (211). By doing so, the air outlet (212) extends from a position lower than the top of the tub body (211), thereby ensuring sufficient space for the circulation fan (1000) to be installed.

[0168] The air inlet (211) may be formed at the top of the inlet (211).

[0169] The above tub (210) may further include a vent hole (215) that is offset to the other side from the top of the tub body (211) and communicates with the outside, and a connecting pipe (216) that communicates the vent hole (215) with the outside of the cabinet (100).

[0170] FIG. 5 illustrates the state in which a circulation duct is installed in the above tub.

[0171] FIG. 5(a) illustrates the tub viewed from the front, and FIG. 5(b) illustrates the tub viewed from the rear.

[0172] The above circulation duct (800) may include a duct body (810) that receives air from an air outlet (212) formed at the upper rear of the tub (210) and discharges air to an air inlet (213) formed at the upper front of the tub (210), and a duct cover (820) that is coupled to the upper part of the duct body (810) and shields the inside of the duct body (810).

[0173] The above duct body (810) can be extended from the rear to the front and can be arranged in a direction corresponding to the front-rear direction of the tub (210) and the drum (220). By doing so, the air resistance flowing through the clothing receiving section (200) and the circulation duct (800) can be reduced.

[0174] The rear connecting part (850) may be provided to connect the rear of the duct body (810) and the air outlet (212), and the front connecting part (840) may be provided to connect the front of the duct body (810) and the air inlet (213).

[0175]

[0176] The above front connecting part (840) may be provided in a square duct shape or in a bellows type. One end or the upper end of the above front connecting part (840) may be connected to the duct body (810), and the other end or the lower end may be connected to the air inlet (213).

[0177] The above rear connecting part (850) may be provided in a pipe shape or in a zarab type.

[0178] However, the rear connecting part (850) may be positioned between the duct body (810) and the tub body (211). Accordingly, the duct body (810) may pressurize the rear connecting part (850) toward the air inlet (212) due to the load. Accordingly, the rear connecting part (850) may be provided such that one end or the upper end is connected to or in close contact with the duct body (810), and the end or lower end is connected to or in close contact with the air inlet (212).

[0179] The above circulation fan (1000) may be positioned with at least a portion between the duct body (810) and the duct cover (820), and may be positioned closer to the rear than to the front of the duct body (810).

[0180] The above circulation fan (1000) may be configured to suck in air from the air outlet (212) and supply it into the duct body (810). That is, the circulation fan (1000) can supply air from inside the tub (210) into the circulation duct (800) at positive pressure.

[0181] A drive unit (300) for rotating the drum (220) may be coupled to the rear of the tub (210). The drive unit (300) may be provided as an outer rotor type.

[0182] FIG. 6 illustrates the positional relationship between the circulation duct of the present invention and the tub.

[0183] The above circulation duct (800) is provided with a resin-based material, and the heat exchanger housed inside may be provided with a metal material. Therefore, the above circulation duct (800) may be susceptible to vibration. In addition, since the above circulation duct (800) has a large self-weight due to the heat exchanger and the circulation fan (1000), it may vibrate with a frequency and amplitude separate from the vibration of the tub (210). As a result, if the above circulation duct (800) is directly seated on the tub (210), a problem may occur in which the above circulation duct (800) and the above tub (210) collide with each other or, in severe cases, are damaged. Therefore, the above circulation duct (800) may be installed inside the cabinet (100) while maintaining a certain distance from the above tub (210).

[0184] The front connecting part (840) and the rear connecting part (850) are coupled to the tub (210), and the duct body (810) may be positioned such that its lower surface is spaced apart from the tub (210) by a specific distance (h). The front connecting part (840) and the rear connecting part (850) are provided with an elastic material to block vibrations and noise from the tub (210) from being transmitted to the duct body (810).

[0185] FIG. 7 illustrates a specific structural embodiment of the above-mentioned duct body.

[0186] The above duct body (810) may include an inlet duct (811) that receives air from the air outlet (212), a fan housing (812) that extends from the inlet duct (811) and accommodates the circulation fan (1000), a connecting duct (813) that extends forward from the fan housing (812), an installation duct (814) that extends forward from the connecting duct (813) and installs a heat exchanger, and an exhaust duct (815) that extends forward or downward from the installation duct (814) and discharges air to the air inlet (213).

[0187] The above inlet duct (811) may be positioned above the air inlet (813) and may be positioned overlapping the air inlet (813) in the height direction.

[0188] The above inlet duct (811) may be provided in the shape of a pipe or in the shape of a through hole so that the above rear connecting part (850) can be connected.

[0189] The rear connecting part (850) may have one end or the lower end connected to or in contact with the air inlet (212), and the other end or the upper end connected to or in contact with the inlet duct (811).

[0190] The above-mentioned fan housing (812) may be provided in a circular or spiral shape.

[0191] The above fan housing (812) is provided to be larger than the diameter or area of ​​the above inlet duct (811) so as to secure a space for the above circulation fan (1000) to be installed.

[0192] The above circulation fan (1000) may be installed in the fan housing (812) to draw in air from the tub (210) and supply it to the heat exchanger.

[0193] The above connecting duct (813) may extend forward from one side of the fan housing (812). The connecting duct (813) may guide the radial airflow formed by the circulation fan (1000) forward.

[0194] The above connecting duct (813) may be configured so that its cross-sectional area gradually widens from the rear toward the front. As a result, the air supplied by the circulation fan (1000) can be distributed evenly as its flow velocity slows down.

[0195] The above installation duct (814) is provided with a width greater than that of the connecting duct (813) so that the heat exchanger can be seated thereon.

[0196] The above installation duct (814) can form a space in which the evaporator and condenser described later are seated.

[0197] The exhaust duct (815) may be formed with a smaller diameter than the installation duct (814). The exhaust duct (815) may be formed so that its width decreases as it extends forward from the installation duct (814). The end of the exhaust duct (815) may be provided with an area and shape corresponding to the air inlet (213).

[0198] The above exhaust duct (815) is extended forward from the above installation duct (814) with a reduced width and can form an opening at the lower front.

[0199] The above duct body (810) may further include a receiving rib (816) that partitions the fan housing (812) and the connecting duct (813) and accommodates a circulation fan (1000).

[0200] The receiving rib (816) may be provided to discharge air circulating around the inner surface of the fan housing (812) forward. That is, the receiving rib (816) can perform the function of an outlet of the fan housing (812) together with one side of the installation duct (813).

[0201] The clothing processing device of the present invention may further include a fixing part (860) that fixes the front and rear of the circulation duct (800) to the cabinet (100) to separate the circulation duct (800) from the tub (210).

[0202] The above fixing part (860) may include a front fixing part (861) provided at the front of the duct body (810) and fixed to the installation panel (120), and a rear fixing part (862) provided at the rear of the duct body (810) and fixed to the rear panel (160).

[0203] For example, the front fixing part (861) may be provided so that a fastening member, etc., can be attached to the front of the exhaust duct (815).

[0204] Additionally, the front fixing part (861) may be provided in the shape of a protruding projection that protrudes from the front of the exhaust duct (815). The front fixing part (861) may be provided in multiple numbers and arranged spaced apart in the width direction in front of the exhaust duct (815). The front fixing part (861) may be inserted into and seated in the panel installation part (121).

[0205] For example, the rear fixing part (862) may be provided so that a fastening member, etc., can be attached to the rear of the fan housing (812).

[0206] Additionally, the rear fixing part (862) may be provided in the shape of a protruding projection that protrudes from the rear of the fan housing (812). The rear fixing part (862) may be provided in multiple numbers and arranged spaced apart in the width direction at the rear of the fan housing (812). The rear fixing part (862) may be inserted into and seated in the panel fixing part (161).

[0207] FIG. 8 illustrates an example of a structure in which a duct body communicates with a tub.

[0208] The above duct body (810) can be extended from the rear to the front of the tub.

[0209] Additionally, the duct body (810) may be provided with a wide width to accommodate the diameter of the circulation fan (1000) in the width direction and to further expand the cross-sectional area. As a result, the duct body (810) may be arranged to completely overlap in the height direction from the top of the air outlet (212) to the top of the air inlet (213).

[0210] Since the air inlet (213) is provided in the input port (214), a space can be formed in which the front connecting part (840) is installed in front of the tub (210).

[0211] However, since the air outlet (212) extends upward from the tub body (211), if the inlet duct (811) is positioned above the air outlet (212), there may be insufficient space for the rear connecting part (850) to be installed or assembled between the air outlet (212) and the inlet duct (811).

[0212] Accordingly, the bracket (830) may be provided to be seated on the upper part of the tub body (211) to connect the rear connecting part (850) to the air outlet (212). The bracket (830) may be coupled to the upper part of the tub body (211) and the lower end of the rear connecting part (850) may be brought into close contact with the air outlet (212).

[0213] The rear connecting part (850) can be connected to the inlet duct (811) at its upper end while fixed to the bracket (830). The duct body (810) can fix the position of the rear connecting part (850) by pressing the rear connecting part (850) toward the bracket (830).

[0214] Figure 9 illustrates the internal configuration of a circulation duct.

[0215] The above circulation fan (1000) can be placed above the inlet duct (811).

[0216] The above circulation fan (1000) may include an impeller (1100) that is housed in the fan housing (812) and introduces air inside the tub body (211), a fan motor (1200) that is seated on the outside of the duct cover (820) and provides power to rotate the impeller (1100), and a rotating shaft (1300) that passes through the duct cover (820) and connects the fan motor (1200) and the impeller (1100).

[0217] The heat exchanger (900) may include an evaporator (910) seated in the installation duct (814) and a condenser (920) spaced apart from the evaporator (910) toward the exhaust duct (815).

[0218] The above evaporator (910) may be positioned behind the above condenser (920) and close to the circulation fan (1000), and the above condenser (920) may be connected to the compressor (940) and the refrigerant pipe (950) to receive high-temperature refrigerant.

[0219] When the fan motor (1200) rotates the impeller (1100), the air inside the tub (210) can be introduced into the inlet duct (811). (1) The air introduced into the inlet duct (811) can be introduced into the installation duct (814) along the connecting duct (813) while rotating radially by the impeller (1100). The air introduced into the installation duct (814) can be cooled as it passes through the evaporator (910) to condense moisture, and heated as it passes through the condenser (920). (2)

[0220] The air passing through the condenser (920) can be discharged through the exhaust duct (815) and then discharged through the air inlet (213). (3)

[0221] This process is performed continuously so that the clothing contained in the drum (220) can be dried.

[0222] Figure 10 illustrates the internal structure of a circulation duct.

[0223] Referring to FIG. 10(a), the diameter (w2) of the fan housing (812) may be larger than half the width (w1) of the installation duct. Thus, as shown in FIG. 10(b), the impeller (1100) may be positioned to rotate around a vertical axis of rotation (1300). As a result, more air inside the tub (210) can be drawn into the duct body (210) with greater force and without loss.

[0224] That is, the diameter (R) of the impeller (1100) is provided to be longer than the thickness (H), and the impeller (1100) can be accommodated inside the fan housing (812) such that the diameter (R) is arranged in the width direction and the thickness (H) is arranged in the up-down direction.

[0225] Referring to FIG. 10(a), due to the receiving rib (816), the rear or inlet width (W3) of the connecting duct (813) can be formed to be smaller than the width of the installation duct (W1) and smaller than the diameter (W2) of the fan housing (812). Additionally, the connecting duct (813) can be configured so that its width gradually increases as it faces the evaporator (810).

[0226] Thus, the connecting duct (813) can function as a diffuser that evenly disperses the air supplied from the fan housing (812) in the width direction toward the front.

[0227] The clothing treatment device of the present invention may further include a nozzle part (3000) capable of cleaning the evaporator (910) by spraying water onto the evaporator (910).

[0228] The nozzle section (3000) may be configured to receive water from the water supply section (410) and spray it onto the evaporator (910). The nozzle section (3000) may be arranged to extend in the width direction of the evaporator (910) so as to supply water to the entire rear surface of the evaporator (910).

[0229] The above circulation duct (800) may be provided to discharge water condensed in the evaporator (910) and water sprayed into the evaporator (910) back to the drain (420) or the tub (210).

[0230] The rear surface of the evaporator (910) corresponds to the area where it is first exposed to the air introduced from the tub (210). Accordingly, the nozzle part (3000) can spray water onto the rear of the evaporator (910) to remove foreign matter adhering to the rear surface of the evaporator (910).

[0231] FIG. 11 illustrates a structure for supplying water to the above-mentioned circulation duct.

[0232] The nozzle part (3000) can be positioned between the lower part of the duct cover (420) and the evaporator (910).

[0233] The above water supply unit (410) may include a water supply pipe (413) connected to the above water supply valve (411) to supply water to the above nozzle unit (3000).

[0234] The above water supply pipes (413) are provided in multiple numbers and can extend from the water supply valve (411) toward both ends of the nozzle section (3000). As a result, water can be evenly supplied to the entire width of the nozzle section (3000).

[0235] FIG. 12 illustrates an embodiment of a structure in which the nozzle part is arranged.

[0236] The nozzle section (3000) may include an inlet pipe (3100) connected to the water supply pipe (413) to receive water supplied from the water supply valve (411), a nozzle body (3200) providing a flow path for the water supplied from the inlet pipe (3100), and a spray hole (3300) that sprays the water flowing through the nozzle body (3200) toward the evaporator (910).

[0237] The nozzle body (3200) may be provided in a duct shape that forms a flow path extending in the width direction of the evaporator (910). The injection hole (3300) may be provided to penetrate the lower part of the nozzle body (3200) and to spray water introduced into the nozzle body (3200). The injection hole (3300) may be provided in multiple numbers and formed along the extension direction of the nozzle body (3200).

[0238] The inlet pipe (3100) may be configured to communicate with the interior of the nozzle body (3200) and to be connected to the water supply pipe (413) on one side of the nozzle body (3200). The inlet pipe (3100) may be configured in a pipe shape.

[0239] The above inlet pipe (3100) may be provided to extend from at least one of the two ends of the nozzle body (3200) to supply water supplied from the water supply pipe (413) to one end of the nozzle body (3200).

[0240] The inlet pipe (3100) may be extended in a direction different from the extension direction of the nozzle body (3200). For example, the inlet pipe (3100) may be extended toward the rear from the back of the nozzle body (3200). This prevents the water supply pipe (413), which is directed from the water supply valve (411) connected to the back panel (160) toward the nozzle body (3200), from being excessively bent or twisted during the process of being connected to the inlet pipe (3100).

[0241] Of course, the inlet pipe (3100) may be extended parallel to the direction in which the nozzle body (3200) extends at least one of the two ends of the nozzle body (3200).

[0242] The nozzle body (3200) may be provided in the shape of a case that temporarily stores water flowing in from the inlet pipe (3100). Accordingly, water flowing in from the inlet pipe (3100) may be prevented from arbitrarily leaking out to an area other than the spray hole (3300).

[0243] Meanwhile, the nozzle part (3000) must be positioned above the evaporator (910) so that the entire rear area of ​​the evaporator (910) can be evenly sprayed with water through the spray hole (3300).

[0244] To this end, the nozzle part (3000) can be coupled and fixed to the duct cover (820). The nozzle part (3000) can be coupled and fixed to the lower surface of the duct cover (820). That is, the nozzle part (3000) can be placed inside the circulation duct (800).

[0245] Thus, the nozzle body (3200) can be formed with an open upper surface and can be sealed by adhering to the lower surface of the duct cover (820). As a result, a complex structure can be freely formed inside the nozzle body (3200), and since the nozzle body (3200) does not need to be divided into upper and lower components for mold placement, the sealing performance of the nozzle part (3000) itself can be improved.

[0246] Meanwhile, if the entire nozzle body (3200) extends in the width direction of the evaporator (910), it may be difficult to supply water to the entire nozzle body (3200) using only the inlet pipe (3100) positioned at the end of the nozzle body (3200). Therefore, the interior of the nozzle body (3200) may be divided left and right or in the width direction of the evaporator (910), and the inlet pipe (3100) may be provided in multiple numbers to spray water into each divided area of ​​the nozzle body (3200).

[0247] For example, the nozzle body (3200) may include a partition rib (3210) that divides the interior into left and right sections. The partition rib (3210) may divide the interior of the nozzle body (3200) into sections of equal length on the left and right sides, or it may divide the interior of the nozzle body (3200) into sections of different lengths on the left and right sides so that water can be sprayed in a larger amount or at a stronger pressure in a specific area.

[0248] The above inlet pipe (3100) may be provided to be positioned at each end of the nozzle body (3200) to supply water to each partitioned area of ​​the nozzle body (3200).

[0249] The above duct cover (820) is provided with a shape corresponding to the above duct body (810) so as to shield the above duct body (810).

[0250] The above duct cover (820) may include a housing cover (821) that shields the fan housing (812), a connection cover (822) that shields the connection duct (813), an installation cover (823) that shields the installation duct (814), and an exhaust cover (824) that shields the exhaust duct (815).

[0251] The nozzle part (3000) can be coupled to the lower surface of the installation duct (814).

[0252] The nozzle part (3000) may include a fastening part (3700) through which a fastening member, which is extended from the nozzle body (3200) and coupled to the installation duct (814), can pass.

[0253] Additionally, the connecting portion (3700) may be arranged to extend in the same direction as the direction in which the inlet pipe (3100) extends from the nozzle body (3200). This ensures that the nozzle body (3200) is not obstructed from adhering to the back surface or the connecting surface (825) of the duct cover (820).

[0254] The above-mentioned fastening portion (3700) may be provided in multiple numbers. The multiple fastening portions (3700) may be spaced apart from each other between the nozzle body (3200) and the inlet pipe (3100) or between both ends of the nozzle body (3200).

[0255] The inlet pipe (3100) may be extended on one side of the nozzle body (3200), and the fastening member (3700) may be extended on the other side of the nozzle body (3200) facing the one side.

[0256] The nozzle body (3200) may further include a fastening hole inside which a fastening member protruding from the duct cover (820) can be inserted and fixed.

[0257] The above fastening holes may also be provided in multiple numbers and arranged spaced apart along the longitudinal direction of the nozzle body (3200).

[0258] The clothing processing device of the present invention may further include a sealing plate (4000) provided to closely contact the upper surface of the nozzle body (3200) and the lower surface of the installation duct (814). The area of ​​the sealing plate (4000) may be equal to or larger than the area of ​​the nozzle body (3200).

[0259] The sealing plate (4000) may be provided with an elastic material. Thus, the nozzle body (3200) can be fixed by pressing against the installation duct (814), and the open upper end of the nozzle body (3200) and the sealing plate (4000) can be in close contact.

[0260] The above installation cover (823) may be recessed upward to accommodate at least a portion of the upper parts of the evaporator (910) and the condenser (920), and may be provided with a coupling surface (825) on the back surface to which the nozzle part (3000) is coupled or to face the nozzle part (3000).

[0261] Since the connecting cover (822) is formed with a width smaller than that of the installation cover (823), the joining surface (825) can be formed in the area connecting the connecting cover (822) and the installation cover (823).

[0262] Of course, the lower end of the above-mentioned joining surface (825) can also be joined to the area extending from both sides of the connecting duct (813) in the upper end of the above-mentioned installation duct (814).

[0263] The nozzle portion (3000) may be disposed on the inner surface of the coupling surface (825), and the inlet pipe (3100) may penetrate the coupling surface (825) and be exposed at the rear of the duct cover (820). Thus, the inlet pipe (3100) may be coupled with the water supply pipe (413) outside the circulation duct (800).

[0264] The above duct cover (820) may include a through hole (826) through which the inlet pipe (3100) can be inserted by penetrating the above coupling surface (825).

[0265] FIG. 13 illustrates the state in which the duct cover and the nozzle part are combined.

[0266] The above duct cover (820) can be attached to the duct body (810) in a state where the nozzle part (3000) is attached first. With the duct cover (820) in an inverted state, a worker can grasp the nozzle part (3000) and first insert the inlet pipe (3100) into the through hole (326), and then attach the nozzle body (3100) to the inner surface of the installation cover (823).

[0267] The above installation cover (823) is provided to accommodate a portion of the upper area of ​​the evaporator (910) and the condenser (920), and since the length of the nozzle body (3100) corresponds to the width of the installation cover (823), it may be somewhat cumbersome to first place the nozzle body (3100) inside the installation cover (823) and then slide the inlet pipe (3100) into the through hole (826).

[0268] Additionally, the duct cover (820) may include a fixing member (827) that protrudes from the lower surface of the installation cover (823) to detachably fix the nozzle part (3000) or support the front surface of the nozzle part (3000).

[0269] The above fixing member (827) may be provided in a hook shape that detachably fixes the nozzle body (3200), may be extended in the width direction, and may be provided in multiple numbers and spaced apart from each other.

[0270] In this case, it may be more difficult for the nozzle part (3000) to first adhere to the inner surface of the installation cover (823) and then move toward the through hole (826).

[0271] Accordingly, when the nozzle part (3000) is mounted on the installation cover (823), the inlet pipe (3100) can be first inserted at an angle toward the through hole (826) while the nozzle body (3100) is completely separated from the installation cover (823), and then the nozzle body (3100) can be rotated to be seated on the installation cover (823).

[0272] Meanwhile, the duct body (820) may further include a plurality of cut grooves (828) through which a refrigerant pipe (950) passing through the evaporator (910) and the condenser (920) can pass.

[0273] The above-mentioned cut groove (828) may be formed on one side of the installation cover (823) that faces the side panel (150) to which the circulation duct (800) is offset.

[0274] FIG. 14 illustrates the process of installing the nozzle part inside the duct body.

[0275] The nozzle part (3000) may be spaced apart from the installation cover (823) and positioned so that the inlet pipe (3100) is inclined toward the through hole (826). The nozzle part (3000) may be moved toward the through hole (826). The inlet pipe (3100) may be moved toward the through hole (826) while the nozzle part (3000) is inclined, and the free end of the inlet pipe (3100) may be inserted into the through hole (826) while inclined. (1)

[0276] When the inlet pipe (3100) is fully inserted into the through hole (826), the nozzle body (3200) can be mounted on the installation cover (823) while rotating toward the inner surface of the installation cover (823) relative to the through hole (826). (2)

[0277] During this process, the inlet pipe (3100) may rub against the inner surface of the through hole (826), and if the thickness of the through hole (826) is thick, a situation may occur where the inlet pipe (3100) cannot rotate in the through hole (826) or is difficult to rotate. Additionally, there is a risk that the nozzle part (3000) and the duct cover (820) may be damaged during the process of the nozzle part (3000) being coupled to the duct cover (820).

[0278] FIG. 15 illustrates an embodiment of the structure of the through hole in which the inlet pipe can be easily inserted and rotated.

[0279] The area of ​​the through hole (826) can be formed to be larger than the cross-sectional area of ​​the inlet pipe (3100). Accordingly, the process of inserting the inlet pipe (3100) into the through hole (826) can be facilitated, and rotating the inlet pipe (3100) inside the through hole (826) to seat the nozzle body (3200) on the duct cover (820) can also be facilitated.

[0280] The cross-section of the inlet pipe (3100) may be circular. However, the through hole (826) may be elliptical or have a track shape in which both sides are straight but the top and bottom are circular.

[0281] Since the inlet pipe (3100) is inserted into the through hole (826) and rotated in the vertical or height direction to seat the nozzle body (3200) on the installation cover (823), the through hole (826) may be formed such that the vertical length (D2) is longer than the width length (D1).

[0282] FIG. 16 illustrates the state in which the nozzle part is installed on the duct cover.

[0283] When the nozzle part (3000) is installed on the duct cover (820), the nozzle body (3200) is fixed to the installation cover (824), and the inlet pipe (3100) can be positioned in a state where it is inserted into the through hole (826).

[0284] The diameter of the inlet pipe (3100) can be formed to be the same as the width-direction diameter (D1) of the through hole (826). Accordingly, air flowing inside the circulation duct (800) can be prevented from leaking out to the left and right of the inlet pipe (3100).

[0285] The upper and lower ends of the through hole (826) may be provided with the same curvature as the outer surface of the inlet pipe (3100). Accordingly, when the outer surface of the inlet pipe (3100) is in close contact with either the upper or lower end of the through hole (826), air flowing inside the circulation duct (800) may be prevented from leaking out through that area.

[0286] However, since the height-direction length (D1) of the through hole (826) is larger than the diameter of the inlet pipe (3100), a gap can be formed between at least one of the upper and lower parts of the inlet pipe (3100) and the through hole (826).

[0287] Of course, the above through hole (826) can be formed at a position where the upper end is in close contact with the upper end of the inlet pipe (3100) while the nozzle body (3200) is seated on the installation cover (823). (The corresponding drawing corresponds to the state where the duct cover (820) is inverted.)

[0288] However, even in this case, the lower end of the through hole (826) may be spaced apart from the lower end of the inlet pipe (3100) to form a spaced-apart space. Therefore, although the through hole (826) is formed larger than the inlet pipe (3100) to increase the ease of installation of the nozzle part (3000), there is a risk that air flowing inside the circulation duct (800) may leak out through the through hole (826).

[0289] FIG. 17 illustrates an embodiment of a nozzle part capable of sealing the through hole.

[0290] The nozzle portion (3000) may further include an extension portion (3500) extending from the outer surface of the inlet pipe (3100) to shield the through hole (826).

[0291] The extension part (3500) can be formed at a position that presses or closes the through hole (826) when the inlet pipe (3100) is completed to the through hole (826).

[0292] The area of ​​the extension part (3500) may be formed to be equal to or larger than the area of ​​the through hole (826). Thus, when the inlet pipe (3100) is inserted into the through hole (826), the extension part (3500) may be provided to cover the entire through hole (826).

[0293] Since the above extension part (3500) must shield the separated area between the through hole (826) and the inlet pipe (3100), it can be extended from the inlet pipe (3100) in a direction away from the nozzle body (3200).

[0294] Of course, the extension portion (3500) may extend to the upper and lower parts of the inlet pipe (3100), and the direction away from the nozzle body (3200) corresponding to the lower part of the inlet pipe (3100) may be extended longer than the direction approaching the nozzle body (3200) from the inlet pipe (3100).

[0295] The width of the extension part (3500) may be formed to be equal to or greater than the width of the inlet pipe (3100).

[0296] The shape of the extension portion (3500) may be formed to correspond to the shape of the through hole (826). Accordingly, the nozzle portion (3000) may be prevented from becoming unnecessarily thick or long.

[0297] The extension portion (3500) may be provided in a plate shape extending vertically from the fixed end of the inlet pipe (3100). The extension portion (3500) may be provided extending from the nozzle body (3200).

[0298] The extension part (3500) can be formed integrally with the nozzle part (3000).

[0299] Meanwhile, the extension portion (3500) may further include an extension rib (3502) disposed along the outer surface of the through hole (826) on one side facing the through hole (826).

[0300] Additionally, when a sealing part (3600) described later is positioned in front of the extension part (3500), the extension part (3500) may further include a guide rib (3502) that guides the positional connection of the sealing part (3600).

[0301] The guide rib (3502) may be formed to protrude in a specific direction from the outer surface of the inlet pipe (3100).

[0302] If the nozzle part (3000) further includes an inlet chamber (3400) that guides water flowing in from the inlet pipe (3100) to the nozzle body (3200), the extension part (3500) may be formed by extending from the outer surface of the inlet chamber (3400).

[0303] FIG. 18 illustrates a nozzle part equipped with the extension part shielding the through hole.

[0304] When the nozzle part (3000) equipped with the extension part (3500) is coupled to the duct cover (820), the inlet pipe (3100) is inserted into the through hole (826), and the extension part (3500) is in close contact with the through hole (826) to shield the through hole (826).

[0305] The above inlet pipe (3100) can be inserted into the through hole (826) until the extension part (3500) comes into close contact with the through hole (826).

[0306] FIG. 19 illustrates an additional embodiment of a nozzle part capable of sealing the through hole.

[0307] The nozzle part (3000) may further include a sealing part (3600) that is coupled to the inlet pipe (3100) and shields the through hole (826).

[0308] The sealing portion (3600) may be detachably provided on the inlet pipe (3100).

[0309] The sealing portion (3600) may be provided so that the inlet pipe (3100) passes through it. That is, the sealing portion (3600) may be coupled to the outer surface of the inlet pipe (3100).

[0310] The sealing portion (3600) may be provided with an elastic member. Accordingly, it can be completely adhered to the outer surface of the through hole (826) to seal the through hole (826).

[0311] The area of ​​the sealing portion (3600) may be larger than the area of ​​the through hole (826). The sealing portion (3600) may be larger in both width and height than the through hole (826). The sealing portion (3600) may be pressed by the inlet pipe (3100) and adhere to the through hole (826).

[0312] Meanwhile, if the sealing part (3600) is provided, the extension part (3500) may be omitted.

[0313] In this case, the shape of the sealing portion (3600) may be provided to be identical to the cross-sectional shape of the inlet pipe (3100). For example, the sealing portion (3600) may be provided in a circular shape having a radius longer than the length of the gap between the inlet pipe (3100) and the through hole (826).

[0314] For example, the maximum diameter of the sealing portion (3600) may be formed to be longer than the height-direction length (D1) corresponding to the major axis of the through hole (826). Thus, the sealing portion (3600) can cover the entire through hole (826).

[0315] Alternatively, the sealing portion (3600) may be provided with a shape different from the cross-sectional shape of the inlet pipe (3100). For example, the sealing portion (3600) may be provided with an elliptical or track shape corresponding to the through hole (826). Thus, even if the shape or area of ​​the inlet pipe (3100) and the through hole (826) are different, the sealing portion (3600) can seal the entire through hole (826).

[0316] Of course, the nozzle part (3000) is provided with the extension part (3500), and the sealing part (3600) is positioned on one side of the extension part (3500) and can be positioned closer to the free end of the inlet pipe (3100) than to the extension part (3500).

[0317] The extension part (3500) may be provided to press the sealing part (3600) into the through hole (826) during the process in which the nozzle part (3000) is mounted on the duct cover (820).

[0318] The area of ​​the extension portion (3500) may be equal to or larger than the area of ​​the sealing portion (3600). By doing so, the extension portion (3500) can induce the entire area of ​​the sealing portion (3600) to press the through hole (826).

[0319] When the sealing portion (3600) is inserted into the inlet pipe (3100), it can be seated on the extension portion (3500). As a result, it can be closely attached to the through hole (826) by the extension portion (3500).

[0320] The sealing portion (3600) may include a sealing body (3610) that shields the through hole (826) and a sealing hole (3620) through which the inlet pipe (3100) passes by penetrating the sealing body (3610).

[0321] Additionally, the sealing portion (3600) may further include a sealing groove (3830) that is recessed in one direction from the outer surface of the sealing hole (3620) so that the guide rib (3501) can be seated thereon. Thus, even if the sealing portion (3600) is provided with a shape different from that of the inlet pipe (3100), it can be induced to be coupled to the inlet pipe (3100) in a position that can shield the through hole (826).

[0322] FIG. 20 illustrates an embodiment in which a nozzle part equipped with the sealing part and the extension part shields a through hole.

[0323] When the sealing portion (3600) is provided, the extension portion (3500) may be positioned so as to be spaced apart from the coupling surface (825) by a certain distance when the inlet pipe (3100) is fully inserted into the through hole (826). By doing so, a space for the sealing portion (3600) to be positioned between the extension portion (3500) and the coupling surface (825) can be secured.

[0324] The thickness of the sealing portion (3600) may be formed to be equal to or greater than the gap between the bonding surface (825) and the extension portion (3500). By doing so, the sealing portion (3600) is pressed against the extension portion (3500) and adheres to the bonding surface (825), thereby sealing the through hole (826).

[0325] FIG. 21 illustrates an additional embodiment of the extension part.

[0326] The extension portion (3500) may be extended at an angle toward the free end of the inlet pipe (3100) as it moves away from the nozzle body (3200).

[0327] The extension portion (3500) may extend in an inclined manner from the nozzle body (3200) toward the inlet pipe (3100).

[0328] Additionally, the extension portion (3500) may be provided such that its thickness increases as it moves further away from the nozzle body (3200). At this time, one side of the extension portion (3500) facing the inlet pipe (3100) may be provided to protrude toward the inlet pipe (3100) as it moves further away from the nozzle body (3200) than the other side on the opposite side.

[0329] Consequently, the extension portion (3500) may be extended at an angle toward the free end of the inlet pipe (3100) or the through hole (826) as the surface facing the through hole (826) moves further away from the nozzle body (3200).

[0330] Thus, the extension part (3500) can be more effectively attached toward the through hole (826).

[0331] Meanwhile, the extension part (3500) may include a shielding body (3510) extending in the vertical direction (Z) or height direction from the nozzle body (3200), and a pressurizing body (3520) disposed on one side facing the inlet pipe (3100) from the shielding body (3510) and facing the through hole (826).

[0332] The above-mentioned pressurized body (3520) may protrude obliquely toward the inlet pipe (3100) with respect to the vertical direction (Z) from the above-mentioned shielding body (3510). The above-mentioned pressurized body (3520) may be provided with a smaller area than the above-mentioned shielding body (3510).

[0333] Thus, when the nozzle part (3000) is connected to the duct body (820), the extension part (3500) can effectively pressurize the through hole (826) over its entire surface area without being separated from the connection surface (825) at least in part.

[0334] Additionally, if a sealing portion (3600) is positioned in front of the extension portion (3500), the extension portion (3500) can press the sealing portion (3600) more strongly toward the inner surface of the joining surface (825).

[0335] FIG. 22 illustrates an additional structure in which the extension part presses the through hole.

[0336] The above duct body (810) may further include a pressurizing part (860) that protrudes upward and pressurizes the extension part (3500).

[0337] When the nozzle part (3000) is coupled to the duct cover (820) and the duct cover (820) is coupled to the duct body (810), the pressurizing part (860) may be provided to press the extension part (3500) toward the through hole (826).

[0338] Thus, the nozzle part (3000) can first press the sealing part (3600) or the through hole (826) when the nozzle body (3200) is coupled to the duct cover (820), and the extension part (3500) can secondarily press the sealing part (3600) or the through hole (826) by the pressurizing part (860) during the process of the duct cover (820) being coupled to the duct body (810).

[0339] Thus, even if the extension part (3500) is extended from the inlet pipe (3100) by the upper length (D2) of the through hole (826), the entire length from the fixed end of the extension part (3500) to the free end of the extension part (3500) can be pressed against the sealing part (3600) or the through hole (826).

[0340] The above pressurizing part (860) may be provided by being coupled to the inside of the installation duct (814) in the duct body (810) or protruding from the inside of the installation duct (814). The above pressurizing part (860) may be provided to be in contact with the other surface of the extension part (3500) in the installation duct (814) that does not face the inlet pipe (3100).

[0341] When the above inlet pipe (3100) and the above extension part (3500) are provided in multiple numbers, the above pressurizing part (860) may also be provided in a number corresponding to the number of the above inlet pipe (3100) and the above extension part (3500).

[0342] FIG. 23 illustrates a specific arrangement and structural embodiment of the above-mentioned pressurizing part.

[0343] The above-mentioned pressurizing member (860) may be provided to pressurize the extension member (3500) without getting caught on or colliding with the free end of the extension member (3500).

[0344] Specifically, the upper or free end of the pressurizing part (860) may be spaced apart from the extension part (3500). That is, the upper end of the pressurizing part (860) may be spaced further from the through hole (826) in the extension part (3500) and positioned closer to the evaporator (910) than to the extension part (3500).

[0345] Additionally, the lower or fixed end of the pressure member (860) may be positioned to overlap with the extension member (3500) in the vertical direction, and may also be positioned closer to the through hole (826) than to the extension member (3500).

[0346] Thus, even if there is a change in the arrangement state of the other side of the extension part (3500) due to tolerances such as the installation position or thickness of the extension part (3500) or the thickness of the sealing part (3600), the pressing part (860) can always press the extension part (3500) toward the through hole (826).

[0347] Specifically, the pressure member (860) may include at least one of a pressure projection (861) provided to press the extension member (3500) and a reinforcing member (862) that reinforces the pressure projection (861).

[0348] The above pressure projection (861) is provided to press the extension part (3500) toward the coupling surface (825), and the reinforcing part (862) may be provided to support the external force applied as a reaction during the process in which the pressure projection (861) presses the extension part (3500).

[0349] The above pressure projection (861) may be provided with a longer protruding height than the above reinforcing part (862), and the above reinforcing part (862) may be provided with a wider or thicker thickness in the front-rear direction than the above pressure projection (861).

[0350] The above pressure projection (861) may include a support (8614) that is coupled to or protrudes from the duct body (810) and is positioned lower than the extension part (3500), a pressure surface (8613) that extends further upward from the support (8614) to pressure the extension part (3500), a guide surface (8612) that extends upward from the pressure surface (8613) and is spaced apart from at least a portion of the extension part (3500), and an upper surface (8611) located at the top of the inclined surface (8612).

[0351] The support member (8614) may be arranged to overlap with the extension member (3500) in the height direction. The pressure surface (8613) may be provided to extend from the duct body (810) or the support member (8614) so ​​as to face the extension member (3500) and to press the extension member (3500) into the through hole (826).

[0352] The above-mentioned pressure surface (8613) may be extended from the support (8614) so ​​as to make surface contact with the other side of the extension (3500). That is, the above-mentioned pressure surface (8613) may be extended upward from the area of ​​the support (8614) that overlaps in height with the other side of the extension (3500).

[0353] The guide surface (8612) may be extended upward at an angle so as to gradually move away from the extension part (3500) at the pressure surface (8613). Additionally, the guide surface (8612) may be extended downward at an angle toward the through hole (826) as it moves from the top of the pressure part (861) or the top surface (8611). Thus, during the process of joining the extension part (3500), the guide surface (8612) guides the extension part (3500) to press against the pressure surface (8613), thereby inducing the through hole (286) to be pressed.

[0354] The reinforcing member (862) can be extended from the duct body (810) to the rear of the pressurized surface (8613) and the support member (8614).

[0355] FIG. 24 illustrates an additional embodiment capable of shielding or sealing the through hole.

[0356] The clothing processing device of the present invention may include a shielding part (870) that extends from the duct body (810) toward the duct cover (820) and shields the space between the through hole (826) and the inlet pipe (3100).

[0357] The shielding portion (870) may include a shielding rib (871) that extends from the duct body (810) to face the joining surface (825) of the duct cover (820).

[0358] The width of the shielding rib (871) may be formed to be equal to or longer than the width of the through hole (826).

[0359] The length of the above shielding rib (871) may be provided such that it makes surface contact with the inlet pipe (3100) connected to the duct cover (820) in the above duct body (810).

[0360] The shielding rib (871) may be provided at any position as long as it is positioned between the through hole (826) and the nozzle body (3100) to shield the through hole (826).

[0361] For example, the shielding rib (871) may be provided to apply pressure between the fixed end and the free end of the inlet pipe (3100).

[0362] The shielding rib (871) may be provided to be in close contact with the joining surface (825) when the duct cover (820) is joined to the duct body (810). The shielding rib (871) may be provided to extend from the installation body (814) toward the outer surface of the inlet pipe (3100). As a result, the shielding rib (871) may be extended to face the through hole (826) to shield the gap between the through hole (826) and the inlet pipe (3100).

[0363] The above shielding rib (871) may be provided to press the inlet pipe (3100) toward the upper end of the through hole (826) during the process in which the duct cover (820) is coupled to the duct body (810). By doing so, the shielding part (870) may induce the outer surface of the inlet pipe (3100) to seal the upper end of the through hole (826), or may directly seal the outer surface of the inlet pipe (3100) and the lower end of the through hole (826).

[0364] The shielding portion (870) may further include a shielding groove (872) provided at the free end or end of the shielding rib (871) to surround or accommodate the outer surface of the inlet pipe (3100).

[0365] The shielding groove (872) may be provided with a curvature corresponding to the curvature of the outer surface of the inlet pipe (3100). Thus, the shielding groove (872) may be provided to be in surface contact with the inlet pipe (3100). As a result, the shielding portion (870) can completely shield the through hole (826) without any gap between the inlet pipe (3100) and the through hole (826).

[0366] The nozzle portion (3000) may be provided with the extension portion (3500) and the sealing portion (3600). In this case, the shielding rib (871) may be inserted between the extension portion (3500) and the sealing portion (3600).

[0367] Alternatively, if the shielding part (870) is provided, the extension part (3500) and the sealing part (3600) may be omitted.

[0368] FIG. 25 illustrates an embodiment of a duct cover combined with the shielding part.

[0369] The shielding portion (870) may be provided to be placed on the inner surface of the coupling surface (825) to shield the through hole (826).

[0370] However, as illustrated, the shielding portion (870) may be provided to be slidably coupled to the back surface of the coupling surface (825) or to the coupling surface (825).

[0371] For example, the lower surface of the coupling surface (825) may be completely open to form a through hole (826) based on the state in which the duct cover (820) is coupled to the duct body (810), and the through hole (826) may be formed on the outer surface of the coupling surface (825) that is exposed to the outside in the thickness direction of the coupling surface (825), and the lower surface of the inner surface of the coupling surface (825) that is exposed to the inside of the circulation duct (820) may be provided with an open bottom.

[0372] That is, the above-mentioned coupling surface (825) may further include a moving groove (829) in which the lower part is open on the inner surface facing the circulation duct (820) so that the shielding rib (871) slides and is coupled.

[0373] The above moving groove (829) can be formed extending from the top of the through hole to the bottom surface of the coupling surface (825).

[0374] The width of the above-mentioned moving groove (829) may be greater than the width (D1) of the above-mentioned through hole (826), and the height of the above-mentioned moving groove (829) may be greater than the height (D2) of the above-mentioned through hole (826).

[0375] The thickness of the above-mentioned moving groove (829) can be formed to be equal to or greater than the thickness of the above-mentioned shielding rib (871).

[0376] Thus, the shielding part (870) is coupled to and fixed to the duct cover (820) so that the through hole (826) can be shielded more securely.

[0377] FIG. 26 illustrates another embodiment of the nozzle part and the duct cover.

[0378] In order to supply water to the entire width direction of the evaporator (910) as much as possible, the nozzle part (3000) may be provided such that the width direction length of the nozzle part (3000) corresponds to 80% to 90% of the width of the installation cover (823).

[0379] However, as the length of the nozzle body (3000) increases, the gap between both sides of the installation cover (823) and both ends of the nozzle body (3000) becomes narrower, making it increasingly difficult to insert the inlet pipe (3100) into the through hole (826).

[0380] Accordingly, the nozzle section (3000) of the present invention can be partitioned in the width direction and provided so as to be separable from one another. As a result, the width of the partitioned nozzle section (3000) becomes smaller than half the width of the installation cover (823), so that each nozzle section (3000) can be easily installed on the installation cover (823).

[0381] Specifically, the nozzle part (3000) may include a first nozzle part (3001) coupled to the lower surface of the duct cover (820) and spraying water in the width direction of the evaporator (910), and a second nozzle part (3002) extending from the first nozzle part (3001) in the width direction of the evaporator and spraying water.

[0382] The first nozzle part (3001) and the second nozzle part (3002) can be provided to be connected to the duct cover (320) respectively while separated from each other. That is, the first nozzle part (3001) and the second nozzle part (3002) can be provided completely separately.

[0383] The first nozzle part (3001) and the second nozzle part (3002) may be provided with the same length as each other, or one of them may be provided with a longer length than the other.

[0384] The above duct cover (820) may include a first through hole (8261) on one side of the coupling surface (826) that connects the first nozzle part (3001) and the water supply valve (411), and a second through hole (8262) spaced apart from the first through hole (8261) in the width direction of the evaporator that connects the second nozzle part (3002) and the water supply valve (411).

[0385] The second through hole (8262) may be positioned on the other side of the coupling surface (826).

[0386] The first nozzle part (3001) may include a first inlet pipe (3101) inserted into the first through hole (8261) to receive water, and a first nozzle body (3201) that extends from the first inlet pipe in the width direction of the evaporator and has a first spray hole (3301) formed therein for spraying water onto the evaporator.

[0387] The second nozzle part (3002) may include a second inlet pipe (3102) inserted into the second through hole (8262) to receive water, and a second nozzle body (3202) that extends from the second inlet pipe (3102) in the width direction of the evaporator (910) and has a second spray hole (3302) formed therein for spraying water onto the evaporator.

[0388] The free end of the first nozzle body (3201) and the free end of the second nozzle body (3202) can be arranged to face each other in the duct cover (820).

[0389] The sum of the length of the first nozzle body (3201) and the length of the second nozzle body (3202) may be provided to correspond to the gap between the first through hole (8621) and the second through hole (8622). Additionally, the gap between the first inlet pipe (3101) and the second inlet pipe (3102) may correspond to the gap between the first through hole (8621) and the second through hole (8622).

[0390] The free end of the first nozzle body (3201) and the free end of the second nozzle body (3202) may be in contact with each other or arranged to face each other in the width direction of the evaporator.

[0391] Accordingly, the free end of the first nozzle body (3201) and the free end of the second nozzle body (3202) may be provided with a curved surface so that installation can be ensured even if they interfere with each other or come into contact with each other during installation.

[0392] FIG. 27 illustrates the process of attaching the nozzle part of FIG. 26 to the duct cover.

[0393] The diameter of the first inlet pipe (3101) may be formed to be equal to or smaller than the diameter of the first through hole (8261), and the diameter of the second inlet pipe (3102) may be formed to be equal to or smaller than the diameter of the second through hole (8262).

[0394] Thus, the first inlet pipe (3101) can be inserted into the first through hole (8261) and rotatably provided, and the second inlet pipe (3102) can be inserted into the second through hole (8262) and rotatably provided. Accordingly, the first inlet pipe (3101) can be provided to rotate the first nozzle body (3201) around the first through hole (8261) while inserted into the first through hole (8261), and the second inlet pipe (3102) can be provided to rotate the second nozzle body (3202) around the second through hole (8262) while inserted into the second through hole (8262).

[0395] Accordingly, with the first nozzle body (3201) separated from the installation cover (823), the first inlet pipe (3101) is inserted into the through hole (8261), and then the first nozzle body (3201) is rotated toward the installation cover (823) to seat the first nozzle body (3201) on the installation cover (823).

[0396] Additionally, with the second nozzle body (3202) separated from the installation cover (823), the second inlet pipe (3102) is inserted into the second through hole (8262), and then the second nozzle body (3202) is rotated toward the installation cover (823) to seat the second nozzle body (3201) on the installation cover (823).

[0397] The free end of the first nozzle body (3201) and the free end of the second nozzle body (3202) are each provided with a curvature by being convex downward or chamfered with respect to the inlet pipe (3100), so that contact or interference with each other can be minimized.

[0398] Therefore, even if the total length of the nozzle part (3000) is long enough to correspond to the width of the duct cover (820), the nozzle part (3000) can be easily installed on the duct cover (820).

[0399] FIG. 28 illustrates an additional embodiment of a duct cover.

[0400] The above duct cover (820) may further include a blocking rib (8230) disposed between the installation cover (823) and the connection cover (822) to prevent backflow of water sprayed from the nozzle part (3000).

[0401] The above blocking rib (8230) is positioned in the above installation cover (823) spaced apart from the evaporator (910) than the nozzle part (3000), and can be positioned closer to the circulation fan (1000) than the nozzle part (3000). As a result, the nozzle part (3000) can be positioned between the blocking rib (8230) and the evaporator (910).

[0402] The above blocking rib (8230) may be extended parallel to the nozzle body (3200) and may be provided longer than the height of the nozzle body (3200).

[0403] The above blocking rib (8230) may be provided in a plate shape.

[0404] The above blocking rib (8230) may be provided with an elastic material.

[0405] Thus, even if water discharged from the injection hole (3300) is sprayed toward the connecting duct (813) due to changes in water pressure or flow rate, it can be blocked by the blocking rib (8230) and prevented from flowing back into the connecting duct (813) or the fan housing (812).

[0406] The present invention may be modified and implemented in various forms, and its scope of rights is not limited to the embodiments described above. Therefore, if a modified embodiment includes the components of the claims of the present invention, it should be considered to fall within the scope of rights of the present invention.
