Description

Technical Field

[0001] The present application relates to the field of household appliance technology, and in particular to a clothing processing device. Background Art

[0002] The heat exchange flow path of a clothing treatment device (such as a heat pump dryer) is equipped with heat exchange components such as an evaporator and condenser. These components convert the moist airflow from the clothing treatment chamber into a dry, hot airflow. The dry, hot airflow then flows back into the chamber, exchanging heat with the wet clothing inside to form a moist airflow. The moist airflow then flows out of the chamber, repeating this cycle to dry the clothing. Because the moist airflow carries debris such as lint, the heat exchange components are prone to lint accumulation after long-term use. Failure to promptly remove these debris from the heat exchange components can not only severely impact heat exchange performance but also create unpleasant odors. Utility Model Content

[0064] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0065] The inventors discovered that the heat exchange flow channel of the clothing processing equipment (such as a heat pump dryer) is provided with heat exchange components such as an evaporator and a condenser. The humid airflow returning from the clothing processing chamber is dried and heated by the heat exchange components to form a high-temperature airflow which is sent to the clothing processing chamber. This cycle is repeated to dry the clothes. Since the humid airflow returning from the clothing processing chamber carries debris such as hair, the humid airflow enters the heat exchange flow channel. The debris such as hair carried by the humid airflow is easily attached to the surface of the heat exchange component. If the debris such as hair on the heat exchange component is not cleaned in time, it will not only seriously affect the heat exchange performance, but also easily produce odor. Based on this, the embodiment of the present application provides a clothing processing device, such as Figure 1 As shown, the clothing treatment device includes a heat exchange component 200 and a nozzle 320 , and the water flow sprayed from the nozzle 320 is used to remove debris such as hair scraps on the surface of the heat exchange component 200 .

[0066] The clothes treating apparatus further comprises a housing, such as Figure 1 and Figure 2As shown, the housing has a heat exchange channel 401, and the heat exchange assembly 200 is disposed in the heat exchange channel 401. The heat exchange assembly 200 includes an evaporator 210. The evaporator 210 is used to cool the airflow in the heat exchange channel 401 to condense the water vapor in the heat exchange channel 401 and reduce the humidity of the airflow in the heat exchange channel 401. The heat exchange assembly 200 also includes a condenser 220. The condenser 220 is used to heat the airflow in the heat exchange channel 401 and increase the temperature of the airflow in the heat exchange channel 401. Through the cooperation of the condenser 220 and the evaporator 210, the humid airflow in the heat exchange channel 401 is converted into dry high-temperature gas for output.

[0067] like Figure 2 As shown, the heat exchange channel 401 may include a return air zone 401a, a cooling zone 401b, a heating zone 401c and an air outlet zone 401d arranged in sequence. The evaporator 210 is arranged in the cooling zone 401b, and the condenser 220 is in the heating zone 401c. The humid airflow entering the heat exchange channel 401 may first enter the cooling zone 401b and be cooled by the evaporator 210, and then enter the heating zone 401c and be heated by the condenser 220 before flowing to the air outlet zone 401d, and finally flow out of the heat exchange channel 401.

[0068] The laundry processing device also includes an inner drum having a laundry processing chamber for accommodating laundry. The laundry processing device has a washing mode and a drying mode. In the washing mode, the inner drum rotates about its central axis to wash laundry, and the laundry processing chamber is sealed between the return air section 401a and the outlet air section 401d. In the drying mode, the laundry processing chamber is connected to the return air section 401a and the outlet air section 401d, respectively, so that air in the laundry processing chamber can pass through the return air section 401a, the cooling section 401b, the heating section 401c, and the outlet air section 401d in sequence before returning to the laundry processing chamber, thereby drying the laundry in the laundry processing chamber.

[0069] It can be understood that since the evaporator 210 is at the front end of the air flow, the humid air flow returning from the clothing processing chamber first contacts the evaporator 210. The humid air flow carries debris such as hair and easily adheres to the surface of the evaporator 210, especially on the windward side 211 of the evaporator 210, which will absorb a larger amount of debris such as hair. If the debris such as hair on the evaporator 210 is not removed in time, the heat exchange performance will be seriously affected.

[0070] like Figure 2 As shown, the nozzle 320 also has a water flow cavity 3201, and the water flow cavity 3201 has a water outlet 3240. The water outlet 3240 is connected to the heat exchange flow channel 401, and can transport water into the water flow cavity 3201 and spray it out through the water outlet 3240 to flush the heat exchange components and other structures in the heat exchange flow channel 401, and wash away the hair and other debris adhering to the heat exchange components and other structures, thereby improving the heat exchange efficiency of the heat exchange components.

[0071] The evaporator 210 has a windward surface 211, which faces the return air zone 401a. The windward surface 211 is angled with the horizontal direction S, so that the windward surface 211 has an appropriate area in contact with the airflow. This also poses the problem of a large amount of debris adhering to the windward surface 211. In this embodiment of the present application, the water outlet 3240 is located adjacent to the windward surface 211 so that the water sprayed from the water outlet 3240 can flush away debris adhering to the windward surface 211.

[0072] like Figure 2 As shown, the evaporator 210 also has a rear side surface 212 facing away from the windward surface 211. In the gravity direction G, the windward surface 211 is located below the water outlet 3240. In the horizontal direction S, at least part of the water outlet 3240 is located behind the windward surface 211.

[0073] The water outlet 3240 of the embodiment of the present application is located above the windward surface 211 and is at least partially arranged toward the portion between the windward surface 211 and the rear side surface 212 of the evaporator 210. The water flowing out of the water outlet 3240 can flow directly to the surface of the evaporator 210 under the action of gravity, and rinse the surface of the evaporator 210 to wash away the debris on the surface of the evaporator 210. Therefore, the clothing processing device of the embodiment of the present application can rinse the surface of the evaporator 210 without flowing airflow in the heat exchange flow channel 401, and there is no need to rely on airflow to drive the water flow to the windward surface 211. The water flow sprayed out of the water outlet 3240 of the present application is more stable.

[0074] Furthermore, when using airflow to drive water to the windward surface 211, the pressure of the airflow can easily cause debris to cling tightly to the surface of the evaporator 210, or even embed itself in gaps within the evaporator 210. In such a situation, spraying water onto the windward surface 211 can make it difficult for some debris to be flushed down, thus affecting the cleaning effect. To ensure that the water ejected from the water outlet 3240 is more accurately directed toward the evaporation surface, the water outlet 3240 needs to be positioned toward the windward surface 211. For example, a structural member with the water outlet 3240 can be positioned to extend beyond the windward surface 211. This structural member can partially overlap the windward surface 211 in the horizontal direction S, disrupting the airflow and increasing wind resistance. It can also block airflow from flowing through the sides of the evaporator 210, reducing heat exchange efficiency. The water outlet 3240 of the embodiment of the present application is located above the windward surface 211. In the gravity direction G, the water outlet 3240 is spaced apart from the evaporator 210. The airflow reaching the windward surface 211 can go around to the top of the evaporator 210, and the airflow is smooth and the heat exchange efficiency is high.

[0075] In some embodiments, the water flow sprayed from the water outlet 3240 is divergent. In the direction of gravity G, the water outlet 3240 and the evaporator 210 are spaced apart so that the water flow sprayed from the water outlet 3240 can cover more areas and clean more areas of the outer surface of the evaporator 210.

[0076] In some embodiments, the water outlet 3240 is located between the windward surface 211 and the rear side surface 212, so that the projection of the water outlet 3240 is entirely within the projection area of the evaporator 210. Among them, in the horizontal direction S, the distance from the water outlet 3240 to the windward surface 211 is less than the distance from the water outlet 3240 to the rear side surface 212. By setting the water outlet 3240 adjacent to the windward surface 211, the water flow ejected from the water outlet 3240 can flow more to the windward surface 211, and the sundries adhered to the windward surface 211 can be washed down. <l

[0077] In some embodiments, as Figure 3 shown, an edge of the windward surface 211 facing the water outlet 3240 forms a first windward edge 211a. In the horizontal direction S, the distance from the water outlet 3240 to the first windward edge 211a is L1, and 0 mm ≤ L1 ≤ 3 mm. Within this distance range, the water flow ejected from the water outlet 3240 can wash the windward surface 211 of the evaporator 210 and the surface adjacent to the windward surface 211, and most of the water flow ejected from the water outlet 3240 can reach the outer surface of the evaporator 210, so as to improve the efficiency of cleaning the sundries on the outer surface of the evaporator 210.

[0078] In some embodiments, the housing has a first water outlet edge 324c and a second water outlet edge 324f. The first water outlet edge 324c and the second water outlet edge 324f enclose to form the water outlet 3240. In the horizontal direction S, the second water outlet edge 324f is located on the side of the first water outlet edge 324c away from the windward surface 211. L1 can be the distance from the first water outlet edge 324c in the horizontal direction S to the first windward edge 211a. In the horizontal direction S, the distance from the second water outlet edge 324f to the first windward edge 211a is L2. Optionally, 0 mm < L2 ≤ 3 mm, and L1 < L2.

[0079] Since the water outlet 3240 is connected to the heat exchange flow channel 401, when the air flow in the heat exchange flow channel 401 flows from the return air area 401a to the air outlet area 401d, it is easy for the air flow that enters the cooling area 401b from the return air area 401a to flow back into the water outlet 3240, interfering with the flow stability of the air flow in the heat exchange flow channel 401. As Figure 4As shown, in some embodiments, the casing is provided with an end flow guiding surface 324d. The end flow guiding surface 324d is connected to the first water outlet edge 324c, and the end flow guiding surface 324d extends along the gravity direction G towards the side where the evaporator 210 is located. The end flow guiding surface 324d protrudes from the plane where the first water outlet edge 324c and the second water outlet edge 324f are located, blocking the backflow of the air flowing from the return air area 401a into the cooling area 401b from entering the water outlet 3240. In addition, the end flow guiding surface 324d is set to extend along the gravity direction G, guiding the water flow ejected from the water outlet 3240 to flow along the gravity direction G, so that more of the water flow ejected from the water outlet 3240 can reach the windward surface 211.

[0080] As Figure 3 and Figure 4 As shown, the end flow guiding surface 324d has a wind blocking edge 324e. The wind blocking edge 324e is located on the side of the first water outlet edge 324c facing the evaporator 210. The wind blocking edge 324e and the second water outlet edge 324f are respectively arranged at intervals from the evaporator 210, and in the gravity direction G, the distance from the wind blocking edge 324e to the windward surface 211 is less than the distance from the second water outlet edge 324f to the windward surface 211. Thus, when the air flows from the return air area 401a to the cooling area 401b, the end flow guiding surface 324d can better block the backflow of the air to the water outlet 3240.

[0081] In some embodiments, the width of the end flow guiding surface 324d along the gravity direction is M, where 0 mm < M ≤ 10 mm. Within this width range, the end flow guiding surface 324d can play the role of blocking the backflow of the air to the water outlet 3240, while guiding the water ejected from the water outlet 3240 to be sprayed onto the surface of the evaporator 210, and imposing less restriction on the spraying range of the water ejected from the water outlet 3240.

[0082] In some embodiments, the first water outlet edge 324c and the second water outlet edge 324f are in the same plane parallel to the horizontal plane, which is convenient for cooperating with the end flow guiding surface 324d to enable the water flow ejected from the water outlet 3240 to reach the surface of the evaporator 210 at an appropriate flow rate and angle. Optionally, the nozzle 320 has a water outlet end wall surface 324g connected to the second water outlet edge 324f. The water outlet end wall surface 324g extends in a direction away from the first water outlet edge 324c, and the water outlet end wall surface 324g is a plane parallel to the horizontal plane. The first water outlet edge 324c and the second water outlet edge 324f are in the plane where the water outlet end wall surface 324g is located.

[0083] Of course, in some other embodiments, the first water outlet edge 324c and the second water outlet edge 324f can also be set in the same plane that forms an angle with the horizontal plane. For example, in the direction of gravity G, the distance from the first water outlet edge 324c to the first windward edge 211a is greater than the distance from the second water outlet edge 324f to the first windward edge 211a, or the distance from the first water outlet edge 324c to the first windward edge 211a is less than the distance from the second water outlet edge 324f to the first windward edge 211a.

[0084] The evaporator 210 also has a top wall, which is set at an angle to the windward surface 211. The water outlet 3240 is facing the top wall of the evaporator 210. The water flow sprayed from the water outlet 3240 has a certain speed. Part of the water flow sprayed from the water outlet 3240 reaches the top wall of the evaporator 210 and flows to the windward surface 211 to flush out debris attached to the surface of the evaporator 210.

[0085] In some embodiments, the top wall of the evaporator 210 is perpendicular to the windward surface 211; or, in the direction of gravity G, the area of ​​the top wall adjacent to the windward surface 211 is inclined toward the side away from the water outlet 3240, so that the water sprayed onto the top wall can flow downstream to the windward surface 211; or, the evaporator 210 has a space connecting the top wall and the windward surface 211, and the water sprayed onto the top wall can flow to the windward surface 211 through the space.

[0086] like Figure 5 As shown, the nozzle 320 has a water outlet section 320b. The nozzle 320 has a first opening wall 3041 and a second opening wall 3042 defining the water outlet section 320b. In the horizontal direction S, the second opening wall 3042 is located on the side of the first opening wall 3041 away from the windward surface 211. The first opening wall 3041 has a first water outlet edge 324c facing the evaporator 210, and the second opening wall 3042 has a second water outlet edge 324f facing the evaporator 210. Fluid entering the water flow cavity 3201 ultimately passes through the water outlet section 320b and is ejected from the water outlet 3240. Optionally, when the nozzle 320 also has an end guide surface 324d, the first opening wall 3041 is configured to have an end guide surface 324d connected to the first water outlet edge 324c.

[0087] In some embodiments, the shape of the outlet flow section 320b can be adjusted by configuring the surface profiles of the first and second walls 3041, 3042, thereby adjusting the velocity and direction of the water ejected from the water outlet 3240. Optionally, along the direction of gravity G, the horizontal distance S between at least a portion of the first wall 3041 (excluding the portion having the end guide surface 324d) and the second wall 3042 gradually decreases. This gradually increases the pressure exerted on the water entering the outlet flow section 320b along the direction of gravity G, thereby enabling the water to be ejected from the water outlet 3240 at a higher velocity.

[0088] In some embodiments, along the gravity direction G, the distance from at least a portion of the first wall 3041 to the windward surface 211 in the horizontal direction S gradually increases, while the distance from the second wall 3042 to the windward surface 211 in the horizontal direction S gradually decreases or remains unchanged. In some embodiments, along the gravity direction G, the distance from at least a portion of the second wall 3042 to the windward surface 211 in the horizontal direction S gradually decreases, while the distance from the first wall 3041 to the windward surface 211 in the horizontal direction S gradually increases or remains unchanged. In some embodiments, along the gravity direction G, the distance from at least a portion of the first wall 3041 to the windward surface 211 in the horizontal direction S gradually increases, while the distance from at least a portion of the second wall 3042 to the windward surface 211 in the horizontal direction S gradually decreases. Using the above-described methods, at least a portion of the distance in the horizontal direction S between the first wall 3041 (excluding the portion having the end guide surface 324d) and the second wall 3042 can be gradually reduced along the gravity direction G.

[0089] In some embodiments, as Figure 5 As shown, the nozzle 320 includes an inlet flow section 320d and an expansion section 320c. The expansion section 320c is connected between the inlet flow section 320d and the outlet flow section 320b. The expansion section 320c is located on the side of the outlet flow section 320b away from the return air region 401a in the horizontal direction S, so that water in the expansion section 320c flows into the outlet flow section 320b on the side of the outlet flow section 320b away from the first opening wall 3041. Optionally, the expansion section 320c is located above the heating zone 401c and the cooling zone 401b of the heat exchange channel 401 to facilitate the positioning of the water flow cavity 3201, making the housing structure compact and facilitating the installation of other structural components of the clothing processing apparatus. At this time, the distance between at least a portion of the second opening wall 3042 and the windward surface 211 in the horizontal direction S may be gradually reduced, so that the second opening wall 3042 guides the water flow to flow smoothly to the water outlet 3240 .

[0090] In some embodiments, as Figure 6 As shown, the first port wall 3041 includes a main flow surface 324a, and the main flow surface 324a has a first water outlet edge 324c. Along the gravity direction G, the distance between the main flow surface 324a and the windward surface 211 in the horizontal direction S remains unchanged. At this time, the main flow surface 324a and the end guide surface 324d are in the same plane. After reaching the main flow surface 324a, part of the water flowing into the water outlet flow section 320b flows downstream to the end guide surface 324d and then flows to the surface of the evaporator 210, and the flow path is smooth.

[0091] In some embodiments, as Figure 7As shown, the first inlet wall 3041 includes a main flow surface 324a, which has a first water outlet edge 324c. Along the gravity direction G, the distance between the main flow surface 324a and the windward surface 211 in the horizontal direction S gradually increases, that is, the main flow surface 324a is inclined toward the side where the second inlet wall 3042 is located, so that the water outlet flow section 320b has more space for accommodating water flow in the area away from the water outlet 3240, and the pressure on the water flow in this area is small. When the water flow reaches the area of ​​the water outlet flow section 320b adjacent to the water outlet 3240, the space is small and the pressure on the water flow is large, so that the pressure difference on the water flow entering different areas of the water inlet flow section 320d is large, so that the speed of the water sprayed out of the water outlet 3240 is large, which can more effectively flush the debris on the surface of the evaporator 210. The water flow sprayed out from the water outlet 3240 has a certain speed and is also divergent. The end guide surface 324d is set to extend along the gravity direction G. The end guide surface 324d is set at an angle to the main guide surface 324a. Through the restriction of the end guide surface 324d, it is also possible to prevent the divergence angle of the water flow sprayed out from the water outlet 3240 from being too large, resulting in part of the water flow being sprayed to the return air area 401a and failing to flow to the surface of the evaporator 210, causing waste, so that more water can flow to the surface of the evaporator 210, thereby improving the flushing efficiency.

[0092] Please refer to Figure 4 The nozzle 320 has a water guide portion 3251, the end of which extends into the water outlet flow section 320b. The walls of the water inlet flow section 320d, the expansion section 320c, the water outlet flow section 320b and the water guide portion 3251 together define the water flow cavity 3201. The water guide portion 3251 is used to guide the water flow in the expansion section 320c to smoothly enter the water outlet flow section 320b.

[0093] In some embodiments, the expansion section 320c is located on the side of the outlet flow section 320b away from the first mouth wall 3041. When the main flow surface 324a is set to be inclined along the gravity direction G toward the side where the second mouth wall 3042 is located, the inclined main flow surface 324a can also reserve an area for water flow buffering, preventing the water flow entering the outlet flow section 320b from the expansion section 320c from directly impacting the first mouth wall 3041 and causing water flow turbulence, so that the water pressure between the second mouth wall 3042 and the main flow surface 324a is small, which facilitates the water flow to smoothly enter the outlet flow section 320b.

[0094] Please refer to Figure 4In some embodiments, the water guide portion 3251 has a water-facing arc surface 325a facing the second mouth wall 3042. The water flow first enters the water outlet section 320b from the space between the second mouth wall 3042 and the water-facing arc surface 325a, then flows to the gap between the second mouth wall 3042 and the main flow surface 324a, and finally is ejected through the water outlet 3240. The water-facing arc surface 325a can guide the water flow entering the water outlet section 320b to change direction, so that the water flow entering the water outlet section 320b can reach the water outlet 3240 more smoothly, thereby reducing flow resistance. The circle where the water-facing arc surface 325a is located has a vertical tangent X, and the first water outlet edge 324c is on the vertical tangent X. The position of the first water outlet edge 324c relative to the water-facing arc surface 325a is appropriate. Under the guidance of the water-facing arc surface 325a, the water flow mainly flows out of the water outlet 3240 along the gravity direction G. Even if the water flow ejected from the water outlet 3240 is divergent under the action of water pressure, it is also convenient to control the direction of the water flow ejected from the water outlet 3240.

[0095] The water guide portion 3251 has a back surface 325b facing the first inlet wall 3041 and a transition arc surface connecting the back surface 325b and the front surface 325a. The first inlet wall 3041 has a diversion base surface 324b connected to the edge of the main diversion surface 324a away from the first outlet edge 324e. The back surface 325b is arranged to be in contact with the diversion base surface 324b of the first inlet wall 3041 to prevent water from entering the area between the back surface 325b and the diversion base surface 324b. In some embodiments, the diversion base surface 324b extends in the direction of gravity, or is inclined toward the side of the second inlet wall 3042 in the direction of gravity, to facilitate the smooth extension of the water guide portion 3251 into the outlet flow section 320b and facilitate assembly.

[0096] The expansion section 320c has an expansion bottom surface 3204 connected to the second opening wall 3042. Figure 5 , along the direction of the water inlet flow segment 320d pointing to the water outlet flow segment 320b, at least a portion of the flow expansion bottom surface 3204 is inclined toward one side of the evaporator 210. Optionally, the flow expansion bottom surface 3204 includes a flow expansion area, a middle area and an inlet area, the middle area is connected between the flow expansion area and the inlet area, the flow expansion area is connected to the second port wall 3042, and at least one of the flow expansion area, the middle area and the inlet area is inclined toward one side of the evaporator 210, so that gravity can be used to enable the water flow in the flow expansion segment 320c to flow smoothly into the water outlet flow segment 320b.

[0097] In some embodiments, the expansion area is located above the cooling zone 401b in the gravity direction G, and the inlet area is located above the heating zone 401c in the gravity direction G, pointing along the water inlet flow section 320d to the water outlet flow section 320b. The middle area of ​​the expansion bottom surface 3204 is inclined toward one side of the evaporator 210, so that the inlet area is higher than the expansion area in the gravity direction G, so that the water flows smoothly from the water inlet flow section 320d to the water outlet flow section 320b. At the same time, it is convenient to avoid more space to supply the heating zone 401c, so that the size of the heating zone 401c in the gravity direction G is larger, so that it can accommodate a larger condenser 220.

[0098] Along the direction from the water inlet flow section 320d to the water outlet flow section 320b, the lateral width of at least part of the expansion section 320c gradually increases. On the one hand, it is convenient to match the size of the evaporator 210, so that the lateral width of the water outlet 3240 is larger, and the surface of the evaporator 210 can be washed over a larger area. On the other hand, the lateral width of the expansion section 320c away from the water outlet flow section 320b is relatively small, which is convenient for planning the structure of the shell so as to arrange the positions of other structural parts of the clothing processing equipment. For example, the part of the casing that limits the expansion section 320c is approximately flat, which is convenient for installing the inner barrel 100 for accommodating clothes on one side of the expansion section 320c in the gravity direction G, and for arranging the structural parts connected to the water inlet flow section 320d in the lateral direction of the expansion section 320c away from the central axis of the inner barrel 100, thereby making full use of the space, making the internal structure of the clothing processing equipment compact, and reducing interference between the various structural parts.

[0099] In some embodiments, along the direction from the inlet flow section 320d to the outlet flow section 320b, at least part of the lateral width of the outlet flow section 320b gradually decreases to reduce the flow area of ​​the outlet flow section 320b, increase the water pressure, and enable the water flow in the outlet flow section 320b to be ejected at a higher speed. Figure 8 As shown, along the direction from the water inlet flow section 320d to the water outlet flow section 320b, the lateral width of the expansion section 320c gradually increases, and the lateral width of the water outlet flow section 320b gradually decreases, so that the water flow can smoothly enter the water outlet flow section 320b and be ejected at a higher speed.

[0100] When the water flows along the direction of the water inlet flow section 320d toward the water outlet flow section 320b, since the lateral width of at least part of the expansion section 320c gradually increases, it is easy to cause the water flow in the lateral edge area of ​​the expansion section 320c to be small. The casing also has a plurality of guide plates 3241 arranged in the expansion area. The plurality of guide plates 3241 are arranged at intervals along the lateral direction of the expansion section 320c, so that the water flow in the expansion section 320c can be more evenly distributed in the lateral direction of the expansion section 320c, and thus enter the outlet flow channel more evenly.

[0101] The housing also has a top diffuser surface 3205, which is positioned opposite the bottom diffuser surface 3204 in the direction of gravity G. A water guide 3251 protrudes from the top diffuser surface 3205 and extends into the outlet flow section 320b. Multiple guide plates 3241 protrude from the diffuser area of ​​the bottom diffuser surface 3204, and their surfaces are respectively attached to the top diffuser surface 3205, creating multiple diversion openings between the top diffuser surface 3205 and the bottom diffuser surface 3204, thereby guiding water more evenly into the outlet flow channel.

[0102] In some embodiments, as Figure 9 As shown, the nozzle 320 includes a first shell 324 and a second shell 325 . The first shell 324 and the second shell 325 are detachably connected, and the first shell 324 and the second shell 325 cover each other to define a water flow cavity 3201 . In some embodiments, the first shell 324 includes a first main board 3224, the first main board 3224 has a flow expansion bottom surface 3204, the second shell 325 includes a second main board 3225, the second main board 3225 has a flow expansion top surface 3205, the first main board 3224 and the second main board 3225 are arranged opposite to each other in the gravity direction G, the first shell 324 also has a water nozzle, the water nozzle extends toward the side away from the second main board 3225, the water nozzle has a first mouth wall 3041 and a second mouth wall 3042, the first mouth wall 3041 and the second mouth wall 3042 together form a water outlet flow section 320b, the second main board 3225 has a water guide portion 3251, the water guide portion 3251 is protruded from the flow expansion top surface 3205 and the end portion extends into the water outlet flow section 320b. The first shell 324 also has two first flanges 3242 protruding from the same side of the first main board 3224, and the second shell 325 also has two second flanges 3252 protruding from the same side of the second main board 3225. The two first flanges 3242 are connected to the two second flanges 3252 in a one-to-one correspondence. The first main board 3224 has a support plate 3248 connected to the first mouth wall 3041. The support plate 3248 extends to a side away from the second mouth wall 3042. The surface of the support plate 3248 is in contact with the surface of the second main board 3225, so that the first main board 3224, the two first flanges 3242, the second main board 3225, the two second flanges 3252, the water guide 3251 and the water nozzle jointly define the water flow cavity 3201.

Among them, during assembly, the first shell 324 and the second shell 325 of the nozzle 320 can be assembled into one, and then installed on the air duct cover 420, and then the nozzle 320 and the air duct cover 420 can be installed together on the air duct base 410. Alternatively, the first shell 324 and the air duct cover 420 of the nozzle 320 can be set as one, and the second shell 325 can be installed on the first shell 324, and then the nozzle 320 and the air duct cover 420 can be installed together on the air duct base 410.

[0105] The chamber housing 400 has a water collection tank connected to the heat exchange flow channel 401, which collects the water flowing down from the evaporator 210. In some embodiments, the clothing processing device further includes a filter assembly for filtering debris from the water flow in the water collection tank to prevent the debris from flowing into other spaces and causing blockage.

[0106] In some embodiments, the laundry processing apparatus further comprises a water pump, which is mounted on the housing. Optionally, the water pump is mounted on the air duct base 410 of the chamber housing 400. The water pump comprises a first water inlet, a second water inlet, and a water outlet.

The water pump is configured to transport water from at least one of the first water inlet and the second water inlet to the water flow chamber 3201 through the water outlet, thereby recycling the water in the water collection tank and saving resources.

[0107] In some embodiments, the laundry processing apparatus further includes a valve body 600 and a water storage box (not shown). The valve body 600 is mounted on the housing.
