[0069] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0070] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "one", "an" and "said" as used herein may also be meant to include plural forms. The terms "comprise", "include", "contain" and "have" are inclusive and therefore specify the presence of stated features, steps, operations, elements and / or parts, but do not exclude the presence or addition of one or more other features, steps, operations, elements, parts, and / or combinations thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring them to be performed in the specific order described or illustrated, unless the order of execution is clearly indicated. It should also be understood that additional or alternative steps may be used.

[0071] Although the terms first, second, third, etc. can be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. Therefore, the first element, component, region, layer or section discussed below can be referred to as the second element, component, region, layer or section without departing from the teaching of the example embodiments.

[0072] For ease of description, spatially relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is flipped, an element described as "below" or "below" another element or feature would then be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be otherwise oriented (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein are interpreted accordingly.

[0073] As shown in Figures 1 to 13, according to an embodiment of the present application, a laundry processing device 100 is provided, which includes a drum assembly 10, a cooling assembly, and a flow guide 30. The drum assembly 10 includes an overflow structure, the cooling assembly includes a liquid outlet 226, and the flow guide 30 includes a liquid flow channel 33, a first liquid inlet structure 34, and a second liquid inlet structure 36. The overflow structure is connected to the liquid flow channel 33 via the first liquid inlet structure 34, and the liquid outlet 226 is connected to the liquid flow channel 33 via the second liquid inlet structure 36.

[0074] When the clothing processing device 100 is washing clothes, when the water in the clothing processing chamber in the drum assembly 10 reaches the highest water level, the water in the clothing processing chamber will overflow through the overflow structure, and the water overflowing through the overflow structure enters the liquid flow channel 33 through the first liquid inlet structure 34. At the same time, when the drying system 20 of the clothing processing device 100 is drying clothes, the air flow is heated and enters the clothing processing chamber, and the hot air flow exchanges heat with the clothes to realize the drying operation of the clothes. The air flow after heat exchange enters the cooling component, and the coolant in the cooling component cools the air flow after heat exchange. The cooled coolant enters the liquid channel through the liquid outlet 226 and the second liquid inlet structure 36.

[0075] It should be understood that, in the present application, the overflow structure of the drum assembly 10 refers to a structure such as an overflow port or overflow joint formed on the drum assembly 10 of the laundry processing device 100. The overflow structure is connected to the position of the highest water level of the laundry processing device 100. When the water level in the laundry processing chamber of the drum assembly 10 reaches the highest water level, if water is continued to be poured into the laundry processing chamber, the water in the laundry processing chamber will overflow through the overflow position. The provision of the overflow structure can prevent the laundry processing device 100 from being unusable due to the excessively high water level in the laundry processing chamber or water from overflowing to the outside of the laundry processing device 100.

[0076] In the prior art, the overflow structure of the drum assembly 10 is connected to the overflow pipe, and the water outlet of the cooling assembly is connected to the water conduit. The overflow pipe and the water conduit are independently arranged structures. The water conduit is a rubber tube. Due to the limited space, the water conduit is not fixed separately, but is fixed by adding a snap structure or other structure to the overflow pipe. When the clothing processing device 100 is in operation and the drum assembly 10 moves (when the inner drum of the drum assembly 10 rotates relative to the outer drum 11, the outer drum 11 will shake or vibrate with the movement of the inner drum), the drum assembly 10, the overflow pipe, and the water conduit move asynchronously. The connection between the overflow pipe, the water conduit, and the drum assembly 10 is prone to loosening. At the same time, friction will occur between the vibrating overflow pipe and the water conduit, or the shaking overflow pipe and the water conduit will rub against other structural components (such as pulleys). This friction will cause wear of the overflow pipe and the water conduit, resulting in water leakage.

[0077] In the clothing processing device 100 of the present application, the flow guide 30 integrates the overflow pipe and the water guide pipe in the prior art. When the flow guide 30 integrating the two functions is used on the clothing processing device 100, the flow guide 30 is fixed on the outside of the drum assembly 10. When the drum assembly 10 is running and moves, the flow guide 30 fixed on the outside of the drum assembly 10 vibrates synchronously with the drum assembly 10, thereby avoiding the situation in the prior art where the overflow pipe and the water guide pipe move asynchronously with each other, causing the connection position to become loose, and also reducing the wear caused by asynchronous movement, thereby effectively improving the reliability of the clothing processing device 100.

[0078] In addition, in the clothing processing device 100 of the present application, the use of the guide member 30 can reduce the use of rubber tubes, improve the convenience of installation, effectively improve the efficiency of installation, and facilitate installation in place, so that the accuracy of installation is effectively improved.

[0079] In the present application, the connection method between the first liquid inlet structure 34 and the overflow structure includes but is not limited to plugging, snapping, welding or bonding.

[0080] Taking the plug-in connection between the first liquid inlet structure 34 and the overflow structure as an example, one of the first liquid inlet structure 34 and the overflow structure is a joint structure, and the other is an interface structure. The joint structure and the interface structure are plugged in and matched (a sealing structure is provided between the joint structure and the interface structure, and the sealing structure is used to seal the joint structure and the interface structure to reduce water leakage. The sealing structure includes but is not limited to a sealing ring or a sealant, etc.). The plug-in assembly method is adopted to facilitate the implementation of the assembly process, which can effectively improve the assembly efficiency and effectively reduce the manufacturing cost.

[0081] At the same time, the connection method between the second liquid inlet structure 36 and the liquid outlet 226 is the same as the connection method between the first liquid inlet structure 34 and the overflow structure. For details, please refer to the implementation method of the connection between the first liquid inlet structure 34 and the overflow structure, which will not be repeated in this application.

[0082] In some embodiments of the present application, as shown in Figures 5 and 6, the liquid flow channel 33 includes a first channel portion 331 and a second channel portion 332, the overflow structure is connected to the first channel portion 331 through the first liquid inlet structure 34, and the liquid outlet 226 is connected to the second channel portion 332 through the second liquid inlet structure 36.

[0083] Specifically, the liquid channel includes a first channel portion 331 and a second channel portion 332. The first channel portion 331 is connected to the overflow structure of the cartridge assembly 10 via the first liquid inlet structure 34, and the second channel portion 332 is connected to the liquid outlet 226 of the cooling assembly via the second liquid inlet structure 36. The first liquid inlet structure 34 and the first channel portion 331 form a first liquid flow path, which is used to guide overflow water from the cartridge assembly 10. The second liquid inlet structure 36 and the second channel portion 332 form a second liquid flow path, which is used to guide the coolant of the cooling assembly.

[0084] By providing the first channel portion 331 and the second channel portion 332, it is possible to separately guide the overflow water of the drum assembly 10 and the coolant of the cooling assembly, thereby reducing the backflow of the coolant through the first liquid inlet structure 34 and the overflow water through the second liquid inlet structure 36, thereby improving the guiding effect of the overflow water and the coolant, and reducing the malfunction of the clothing processing device 100 due to the inability to effectively discharge the overflow water or the coolant.

[0085] It should be pointed out that in the present application, the first channel portion 331 and the second channel portion 332 are not connected to each other. The first channel portion 331 and the second channel portion 332 are two completely independent channels, and the liquid channels can be separated by a structure.

[0086] Furthermore, the shape of the flow cross section of the first channel portion 331 includes, but is not limited to, a circle, a square, a triangle, a pentagon, a hexagon, a rhombus, or an ellipse, and similarly, the shape of the flow cross section of the second channel portion 332 also includes, but is not limited to, a circle, a square, a triangle, a pentagon, a hexagon, a rhombus, or an ellipse, etc. The flow cross section shape of the first channel portion 331 and the flow cross section shape of the second channel portion 332 can be the same or different, and the flow cross section shape of the first channel portion 331 and the flow cross section shape of the second channel portion 332 can be set according to specific applications and manufacturing requirements.

[0087] In some embodiments of the present application, as shown in Figures 2 to 6, the guide member 30 further includes a first liquid outlet structure 35, the clothing processing device 100 further includes a drainage assembly, and the first channel portion 331 is connected to the drainage assembly through the first liquid outlet structure 35.

[0088] Specifically, the flow guide 30 is fixedly mounted on the outside of the drum assembly 10, and a first liquid inlet structure 34 and a first liquid outlet structure 35 are respectively provided on the flow guide 30. The first channel portion 331 of the flow guide 30 is connected to the overflow structure of the drum assembly 10 via the first liquid inlet structure 34, and the first channel portion 331 is connected to the drain assembly via the first liquid outlet structure 35. When the water level in the laundry treatment chamber of the drum assembly 10 reaches the maximum water level, the water in the laundry treatment chamber enters the first channel portion 331 through the overflow structure and the first liquid inlet structure 34, and then flows into the drain assembly through the first liquid outlet structure 35 for discharge, thereby reducing the possibility of water in the laundry treatment chamber overflowing to the outside, thereby effectively improving the user experience.

[0089] It should be noted that in the present application, the drainage assembly includes a drain pipe 50, one end of which is connected to the first liquid outlet structure 35, and the other end of the drain pipe 50 is connected to the sewer. The drain pipe 50 is used to discharge overflow water discharged from the first liquid outlet structure 35 into the sewer, thereby effectively treating the overflow water and reducing the situation where the overflow water overflows onto the floor and other locations, thereby reducing the user experience. Among them, the first liquid outlet structure 35 is a joint structure, and the drain pipe 50 is mounted on the first liquid outlet structure 35 and fixed to the first liquid outlet structure 35 by fasteners such as clamps to prevent the drain pipe 50 from falling off. At the same time, it can also achieve a sealing of the connection between the first liquid outlet structure 35 and the drain pipe 50.

[0090] In some embodiments of the present application, as shown in Figures 5 and 6, the first liquid inlet structure 34 is connected to one end of the first channel portion 331, and the first liquid outlet structure 35 is connected to the other end of the first channel portion 331. The first liquid outlet structure 35 is located below the first liquid inlet structure 34.

[0091] Specifically, the first liquid inlet structure 34 is connected to the overflow structure of the barrel assembly 10, and the first liquid outlet structure 35 is connected to the drainage assembly. By arranging the first liquid outlet structure 35 below the first liquid inlet structure 34, the overflow water entering the clothing processing chamber can enter the first channel portion 331 through the first liquid inlet structure 34. The overflow water can naturally flow to the first liquid outlet structure 35 under the action of gravity, and flow into the drainage assembly through the first liquid outlet structure 35 to achieve the natural outflow of the overflow water, thereby eliminating the need to set a power component (such as a water pump, etc.) for driving the discharge of the overflow water, thereby reducing the number of components, and effectively reducing the manufacturing cost of the clothing processing device 100.

[0092] It should be understood that the first liquid outlet structure 35 being located below the first liquid inlet structure 34 may mean that the first liquid outlet structure 35 is located directly below the first liquid inlet structure 34 , or that the first liquid outlet structure 35 is located obliquely below the first liquid inlet structure 34 .

[0093] In some embodiments of the present application, as shown in FIG. 5 and FIG. 6 , the first channel portion 331 includes at least one U-shaped bend 3311 , and the at least one U-shaped bend 3311 is disposed between the first liquid inlet structure 34 and the first liquid outlet structure 35 .

[0094] Specifically, the flow guide 30 is fixedly mounted on the outside of the drum assembly 10, and the first liquid outlet structure 35 is located below the first liquid inlet structure 34. The first liquid inlet structure 34 is connected to the overflow structure of the drum assembly 10, and the first liquid outlet structure 35 is connected to the drainage assembly of the laundry processing device 100. When the water level in the laundry processing chamber of the drum assembly 10 reaches the maximum water level, the water in the laundry processing chamber enters the interior of the first channel portion 331 through the overflow structure and the first liquid inlet structure 34, and then reaches the position of the first liquid outlet structure 35 through the first channel portion 331. Then, it flows into the drainage assembly through the first liquid outlet structure 35 and is discharged to the sewer.

[0095] At least one U-shaped bend 3311 is provided in the area of ​​the first channel portion 331 located between the first liquid inlet structure 34 and the first liquid outlet structure 35, and the communicating vessel principle of the U-shaped bend 3311 is utilized to form a water-sealed structure, thereby reducing the odor phenomenon in the sewer and improving the user experience during use.

[0096] It should be understood that, in the present application, the U-shaped bend 3311 is a positive U-shaped bend 3311 or an inverted U-shaped bend 3311 .

[0097] It should be noted that, in the present application, the number of U-shaped bends 3311 can be one, two, three, four or five, etc.

[0098] As shown in Figures 5 and 6, when there are multiple U-shaped bends 3311, the multiple U-shaped bends 3311 can be connected in sequence to form a serpentine structure (positive U-shaped bends 3311 and inverted U-shaped bends 3311 are arranged alternately), thereby further improving the water sealing effect.

[0099] In some embodiments of the present application, as shown in FIG5 and FIG6 , the flow guide 30 further includes a second liquid outlet structure 37 , the cartridge assembly 10 further includes a water return structure, and the second channel portion 332 is connected to the water return structure through the second liquid outlet structure 37 .

[0100] Specifically, the flow guide 30 is fixedly mounted on the outside of the drum assembly 10, and a second liquid inlet structure 36 and a second liquid outlet structure 37 are respectively provided on the flow guide 30. The second channel portion 332 of the flow guide 30 is connected to the liquid outlet 226 of the cooling assembly via the second liquid inlet structure 36, and the second channel portion 332 is connected to the return structure of the drum assembly 10 via the second liquid outlet structure 37. When the laundry processing apparatus 100 is drying clothes, the drying system 20 of the laundry processing apparatus 100 heats the airflow. The heated airflow enters the laundry processing chamber and exchanges heat with the clothes to dry the clothes. After the heat exchange, the airflow enters the cooling assembly. The coolant in the cooling assembly exchanges heat with the airflow to cool the airflow. The coolant after the heat exchange also enters the second channel portion 332 via the second liquid inlet structure 36. The coolant entering the second channel portion 332 enters the interior of the drum assembly 10 via the second liquid outlet structure 37 and the return structure to achieve unified treatment of the coolant.

[0101] In some embodiments of the present application, the return water structure is connected to the outer cylinder 11 of the cylinder assembly 10, and is connected between the outer cylinder 11 and the inner cylinder. The coolant enters between the outer cylinder 11 and the inner cylinder through the return water structure, and is uniformly discharged through the discharge position of the washing water, so as to achieve unified treatment of the coolant.

[0102] In addition, a corresponding temperature detection element (such as a temperature sensor, etc.) can be set at the position of the return water structure to detect the return water temperature of the coolant using the temperature detection element, so as to indirectly judge the cooling effect of the cooling component using the return water temperature.

[0103] In addition, in the present application, the connection method between the second liquid outlet structure 37 and the water return structure includes but is not limited to plugging, snapping, welding or bonding.

[0104] Taking the plug-in connection between the second liquid outlet structure 37 and the return water structure as an example, one of the second liquid outlet structure 37 and the return water structure is a joint structure, and the other is an interface structure. The joint structure and the interface structure are plugged in and matched (a sealing structure is provided between the joint structure and the interface structure, and the sealing structure is used to seal the joint structure and the interface structure to reduce water leakage. Among them, the sealing structure includes but is not limited to a sealing ring or sealant, etc.). The plug-in assembly method facilitates the implementation of the assembly process, can effectively improve the assembly efficiency, and effectively reduce the manufacturing cost.

[0105] In some embodiments of the present application, as shown in FIG. 5 and FIG. 6 , the guide member 30 further includes a plurality of ribs 38 , which are disposed inside the guide member 30 and separate the first channel portion 331 and the second channel portion 332 within the guide member 30 .

[0106] Specifically, a liquid channel is provided inside the guide member 30, and a rib plate 38 is provided in the liquid channel. There are multiple rib plates 38, and the multiple rib plates 38 separate the liquid channel into a first channel portion 331 and a second channel portion 332. The first liquid inlet structure 34 and the first liquid outlet structure 35 are respectively connected to the first channel portion 331, and the second liquid inlet structure 36 and the second liquid outlet structure 37 are respectively connected to the second channel portion 332.

[0107] The ribs 38 are used to separate the liquid channel so that the first channel portion 331 and the second channel portion 332 can be integrated into the interior of the flow guide 30, thereby optimizing the structure, reducing the overall volume, and effectively reducing the manufacturing cost.

[0108] In the present application, the flow guide 30 is an integrated structure. When the flow guide 30 is an integrated structure, it can be manufactured by casting; or it can be manufactured by injection molding and then assembled.

[0109] Furthermore, there are multiple ribs 38 that enclose the first channel portion 331. Adjacent ribs 38 are staggered at the U-shaped bend 3311 of the first channel portion 331, thereby forming the U-shaped bend 3311. Furthermore, when there are multiple U-shaped bends 3311, adjacent ribs 38 are staggered to form a sequentially connected maze structure, thereby reducing the risk of odor regurgitation.

[0110] In some embodiments of the present application, as shown in Figures 3 to 5, the guide member 30 includes a first body 31 and a second body 32, and a plurality of ribs 38 are provided on the first body 31 and / or the second body 32. The first body 31, the second body 32 and the plurality of ribs 38 surround a first channel portion 331 and a second channel portion 332.

[0111] Specifically, the plurality of ribs 38 used to separate and form the first channel portion 331 and the second channel portion 332 can be entirely disposed on the first body 31, entirely disposed on the second body 32, or partially disposed on the first body 31 and partially disposed on the second body 32. When the first body 31 and the second body 32 are mated with each other, the first body 31 and the second body 32 together form a chamber structure, and the plurality of ribs 38 are located within and separate the chamber structure to form the first channel portion 331 and the second channel portion 332.

[0112] The matching manner between the first body 31 and the second body 32 includes but is not limited to welding, bonding, riveting, clamping or screw connection.

[0113] In some embodiments of the present application, as shown in FIG. 3 to FIG. 5 , at least one connecting structure 39 is provided on the flow guide 30 , and the at least one connecting structure 39 is fixedly connected to the outer cylinder 11 of the cylinder assembly 10 .

[0114] Specifically, the guide member 30 is installed and fixed on the outside of the barrel assembly 10 through the connecting structure 39. By setting the connecting structure 39, it is convenient to assemble the guide member 30, thereby effectively improving the assembly efficiency and reducing the production cost.

[0115] It should be noted that, in the present application, the connection structure 39 includes but is not limited to a buckle or a connection hole. For example, if the connection structure 39 is a connection hole, when the flow guide 30 is connected and fixed to the outer cylinder 11 of the cylinder assembly 10, a screw can be passed through the connection hole to connect and fix the flow guide 30 to the outer cylinder 11.

[0116] In some embodiments of the present application, as shown in Figures 1, 2, 8 to 13, the cooling assembly also includes a condenser 22, the condenser 22 includes a shell 221, an air inlet 223, an air outlet 224, a liquid inlet 225 and a liquid outlet 226 and a blocking structure 227, wherein a fluid channel 222 is defined inside the shell 221, the air inlet 223, the fluid channel 222, and the air outlet 224 are interconnected to form a gas flow path, the liquid inlet 225, the fluid channel 222 and the liquid outlet 226 are interconnected to form a liquid flow path, the blocking structure 227 is located inside the fluid channel 222, and the blocking structure 227 is located on the gas flow path.

[0117] It should be understood that in the present application, the air inlet 223, the air outlet 224, the liquid inlet 225 and the liquid outlet 226 are arranged at intervals on the shell 221, and the air inlet 223, the air outlet 224, the liquid inlet 225 and the liquid outlet 226 are respectively connected to the fluid channel 222 inside the shell 221, wherein the liquid inlet 225 receives the coolant so that the coolant can enter the fluid channel 222, the liquid outlet 226 is used to discharge the coolant from the fluid channel 222, the air inlet 223 is used to receive the airflow to be cooled, and the air outlet 224 discharges the cooled airflow from the fluid channel 222.

[0118] In this application, the gas flow path refers to the path for gas to flow on the condenser 22. Specifically, the gas enters the fluid channel 222 through the air inlet 223, and the gas entering the fluid channel 222 flows in the fluid channel 222 toward the air outlet 224 and is discharged from the condenser 22 through the air outlet 224.

[0119] The liquid flow path refers to the path for liquid to flow on the condenser 22. Specifically, the coolant enters the fluid channel 222 through the liquid inlet 225, flows in the fluid channel 222 toward the liquid outlet 226, and is discharged from the condenser 22 through the liquid outlet 226.

[0120] When the condenser 22 is in use, the coolant enters the fluid channel 222 through the liquid inlet 225, and the coolant entering the fluid channel 222 flows along the liquid flow path. The airflow after the drying system 20 completes the heat exchange with the clothes is passed into the fluid channel 222 through the air inlet 223, and the airflow entering the fluid channel 222 flows along the gas flow path. The gas flowing on the gas flow path exchanges heat with the coolant flowing on the liquid flow path to achieve cooling of the gas. The cooled gas returns to the drying system 20 through the air outlet 224 to exchange heat with the clothes again, and the coolant after heat exchange flows out through the liquid outlet 226.

[0121] In the fluid channel 222, during the heat exchange process between the coolant and the airflow, the coolant is easy to flow along the gas flow path with the airflow. The present application sets a blocking structure 227 on the gas flow path, and uses the blocking structure 227 to block the coolant, thereby reducing the flow of the coolant along the gas flow path, thereby reducing the flow of the coolant along the airflow through the air outlet 224, and further reducing the malfunction of the drying system 20 caused by the coolant entering the drying system 20.

[0122] It should be pointed out that in the present application, the coolant flow path and the gas flow path are at least partially intersected in the fluid channel 222. By intersecting the coolant flow path and the gas flow path, the gas needs to pass through the coolant during the flow process, so that the gas can fully contact the coolant, thereby improving the heat exchange effect between the coolant and the airflow, and improving the cooling effect on the gas.

[0123] In addition, the liquid outlet 226 of the condenser 22 is connected to the second liquid inlet structure 36 of the guide member through a connecting pipe.

[0124] In addition, the drying system 20 of the clothing processing device 100 includes an air duct assembly, and the fan 21 of the air duct assembly is connected to the air outlet 224 of the condenser 22. Under the suction action of the fan 21, the gas in the fluid channel 222 is extracted through the air outlet 224.

[0125] In some embodiments of the present application, as shown in FIG. 12 and FIG. 13 , the blocking structure 227 is located between the liquid inlet 225 and the gas outlet 224 .

[0126] In some embodiments of the present application, the air inlet 223, the air outlet 224, the liquid inlet 225 and the liquid outlet 226 are respectively arranged on the shell 221 and are connected to the fluid channel 222 inside the shell 221. The coolant enters the fluid channel 222 through the liquid inlet 225 and flows along the liquid flow path, and finally discharges the fluid channel 222 through the liquid outlet 226. The gas enters the fluid channel 222 through the air inlet 223 and flows along the gas flow path, and finally is discharged through the air outlet 224.

[0127] The blocking structure 227 is arranged between the liquid inlet 225 and the air outlet 224, which reduces the situation where the coolant is carried out of the fluid channel 222 along with the gas through the air outlet 224 during the process of entering the fluid channel 222 through the liquid inlet 225, further reduces the situation where the coolant flows out through the air outlet 224, thereby further reducing the situation where the coolant enters the drying system 20 and causes the drying system 20 to malfunction.

[0128] In some embodiments of the present application, as shown in Figures 11 to 13, the shell 221 includes a top wall 2221, a bottom wall 2222, a first side wall 2223, a second side wall 2226, a first end wall 2224 and a second end wall 2225. The top wall 2221, the bottom wall 2222, the first side wall 2223, the second side wall 2226, the first end wall 2224 and the second end wall 2225 together form a fluid channel 222. The top wall 2221 and the bottom wall 2222 are arranged opposite to each other, the first side wall 2223 and the second side wall 2226 are arranged opposite to each other, and the first end wall 2224 and the second end wall 2225 are arranged opposite to each other.

[0129] Specifically, the fluid channel 222 is formed by the top wall 2221, the bottom wall 2222, the first side wall 2223, the second side wall 2226, the first end wall 2224 and the second end wall 2225. The top wall 2221, the bottom wall 2222, the first side wall 2223 and the second side wall 2226 form a cylindrical structure with two ends open. The bottom wall 2222 is arranged opposite to the top wall 2221, and the first side wall 2223 and the second side wall 2226 are arranged opposite to each other. The first end wall 2224 is provided at one end of the cylindrical structure, and the first end wall 2224 is respectively connected to the top wall 2221, the bottom wall 2222, the first side wall 2223 and the second side wall 2226 to close an opening of the cylindrical structure. The second end wall 2225 is provided at the other end of the cylindrical structure, and the second end wall 2225 is respectively connected to the top wall 2221, the bottom wall 2222, the first side wall 2223 and the second side wall 2226 to close the other opening of the cylindrical structure.

[0130] In some embodiments of the present application, as shown in Figures 12 and 13, the air inlet 223 is arranged on the first end wall 2224, and the top wall 2221 includes a first top wall 22211, a second top wall 22212 and a third top wall 22213 connected in sequence, wherein the first top wall 22211 is connected to the first end wall 2224, the third top wall 22213 is connected to the second end wall 2225, the liquid inlet 225 is arranged on the first top wall 22211, the air outlet 224 is arranged on the third top wall 22213, and a blocking structure 227 is provided on the first top wall 22211 or the second top wall 22212.

[0131] Specifically, the air outlet 224 and the liquid inlet 225 are both arranged on the top wall 2221, and a blocking structure 227 is provided between the air outlet 224 and the liquid inlet 225, wherein the top wall 2221 includes a first top wall 22211, a second top wall 22212 and a third top wall 22213 connected in sequence, the liquid inlet 225 is arranged on the first top wall 22211, the air outlet 224 is arranged on the third top wall 22213, and the blocking structure 227 is arranged on the first top wall 22211 or the second top wall 22212. When the condenser 22 is in use, the coolant enters the fluid channel 222 through the liquid inlet 225, and the gas to be cooled enters the fluid channel 222 through the air inlet 223. During the flow of the gas, part of the coolant will flow along the top wall 2221 along the gas flow path with the gas. A blocking structure 227 is provided on the top wall 2221 (the first top wall 22211 or the second top wall 22212). The blocking structure 227 is used to block the coolant flowing along the top wall 2221 to the air outlet 224, so as to reduce the outflow of the coolant through the air outlet 224.

[0132] It should be understood that when the condenser 22 of the present application is in use, the condenser 22 is mounted and fixed on the outside of the drum assembly 10 of the clothing processing device 100, and the top wall 2221 of the housing 221 is located above the bottom wall 2222. At this time, the liquid inlet 225 is opened on the first top wall 22211 of the top wall 2221, so that after the coolant enters the cooling channel through the liquid inlet 225, it can fall toward the bottom wall 2222 under the action of its own gravity, thereby being arranged away from the air outlet 224, thereby reducing the possibility of the coolant flowing toward the air outlet 224 along with the gas. At the same time, the air outlet 224 is arranged on the third top wall 22213 of the top wall 2221, so that the direction in which the airflow exits the fluid channel 222 is arranged upward. By arranging the air outlet 224 on the third top wall 22213,

[0133] It should be pointed out that the blocking structure 227 provided on the first top wall 22211 or the second top wall 22212 is protruded from the top wall 2221, and one end of the blocking structure 227 is connected to the first side wall 2223, and the other end of the blocking structure 227 is connected to the second side wall 2226. By setting the blocking structure 227, the blocking structure 227 forms a better blocking effect on the coolant on the top wall 2221, reducing the situation where the blocking structure 227 flows along the top wall 2221 to the air outlet 224.

[0134] In some embodiments of the present application, as shown in Figures 11 to 13, the bottom wall 2222 is provided with a blocking structure 227, and the size of the blocking structure 227 in the direction from the first side wall 2223 to the second side wall 2226 is smaller than or equal to the size of the bottom wall 2222.

[0135] Specifically, among the walls forming the fluid channel 222 , the top wall 2221 and the bottom wall 2222 are arranged opposite to each other, and the liquid inlet 225 and the gas outlet 224 are respectively arranged on the top wall 2221 . When the condenser 22 is in use, the coolant enters the fluid channel 222 through the liquid inlet 225, and the gas to be cooled enters the fluid channel 222 through the air inlet 223. The coolant circulates along the liquid flow path, and the gas flows along the gas flow path. The gas exchanges heat with the coolant during the flow process. The coolant after heat exchange falls onto the bottom wall 2222 under the action of its own gravity. The coolant that falls onto the bottom wall 2222 flows along the liquid flow path on the bottom wall 2222. By arranging a blocking structure 227 on the bottom wall 2222, the blocking structure 227 is used to block the coolant flowing along the bottom wall 2222, so that the coolant can flow along the liquid flow path, so as to reduce the situation where the coolant flows along the bottom wall 2222 to the bottom of the air outlet 224 and is sucked out of the air outlet 224.

[0136] It should be pointed out that the blocking structure 227 provided on the bottom wall 2222 protrudes from the bottom wall 2222. Along the direction from the first side wall 2223 to the second side wall 2226, when the size of the blocking structure 227 is equal to the size of the bottom wall 2222, the blocking structure 227 is respectively connected to the first side wall 2223 and the second side wall 2226. When the size of the blocking structure 227 is smaller than the size of the bottom wall 2222, the two ends of the blocking structure 227 can be respectively spaced apart from the first side wall 2223 and the second side wall 2226, or one end can be connected to one of the first side wall 2223 and the second side wall 2226, and the other end can be spaced apart from the other of the first side wall 2223 and the second side wall 2226.

[0137] In some embodiments of the present application, as shown in Figures 12 and 13, along the length direction of the fluid channel 222, the bottom wall 2222 includes a first bottom wall 22221 and a second bottom wall 22222 connected to each other, the second bottom wall 22222 is provided with a liquid outlet 226, and the second bottom wall 22222 is arranged lower than the first bottom wall 22221.

[0138] Specifically, among the walls that enclose the fluid channel 222, the top wall 2221 and the bottom wall 2222 are disposed opposite each other, the liquid inlet 225 is disposed on the first top wall 22211 of the top wall 2221, and the liquid outlet 226 is disposed on the second bottom wall 22222. When the condenser 22 is in use, coolant enters the fluid channel 222 through the liquid inlet 225 and flows along the liquid flow path. Gas enters the fluid channel 222 through the air inlet 223 and flows along the gas flow path. During the flow, the gas exchanges heat with the coolant to cool the gas. The cooled gas is discharged through the air outlet 224, and the coolant after heat exchange is discharged through the liquid outlet 226. By positioning the second bottom wall 22222 lower than the first bottom wall 22221, the coolant can be collected at the location of the liquid outlet 226, thereby improving the coolant discharge efficiency and reducing the problem of bacterial growth caused by coolant residue in the condenser 22.

[0139] It should be pointed out that in the present application, the first bottom wall 22221 is arranged at an angle, and the second bottom wall 22222 is connected to the lowest position of the first bottom wall 22221. The inclined first bottom wall 22221 has a better guiding effect on the coolant, so that the cold zone liquid can flow quickly from the first bottom wall 22221 to the second bottom wall 22222, and then be discharged through the liquid outlet 226.

[0140] In addition, the second end wall 2225 of the fluid channel 222 is connected to the second bottom wall 22222, and the liquid outlet 226 is provided at the connection position between the two.

[0141] In some embodiments of the present application, as shown in Figures 11 to 13, the first bottom wall 22221 includes a first portion 22221a, a second portion 22221b, and a third portion 22221c. The second portion 22221b is connected to the first side wall 2223 via the first portion 22221a, and the second portion 22221b is connected to the second side wall 2226 via the third portion 22221c. The first portion 22221a, the second portion 22221b, and the third portion 22221c are stepped, with the third portion 22221c being lower than the first portion 22221a. The first portion 22221a is an arched structure that arches toward the interior of the fluid channel 222 and is provided with a blocking structure 227. The third portion 22221c is an inclined structure, and the lowest position of the third portion 22221c is connected to the second bottom wall 22222.

[0142] Specifically, among the walls that form the fluid channel 222, the top wall 2221 is arranged opposite to the bottom wall 2222, and the top wall 2221 includes a first top wall 22211, a second top wall 22212, and a third top wall 22213 that are sequentially connected along the length direction of the fluid channel 222, and the bottom wall 2222 includes a first bottom wall 22221 and a second bottom wall 22222 that are sequentially connected along the length direction of the fluid channel 222. The first top wall 22211 and the second top wall 22212 are connected to the bottom wall 22213. The first bottom wall 22221 is arranged opposite to each other, and the third top wall 22213 is arranged opposite to the second bottom wall 22222. A blocking structure 227 is provided on the first top wall 22211 or the second top wall 22212, a liquid inlet structure is provided on the first top wall 22211, an air outlet 224 is provided on the third top wall 22213, a blocking structure 227 is also provided on the first part 22221a of the first bottom wall 22221, and a liquid outlet 226 is provided on the second bottom wall 22222.

[0143] When the condenser 22 is in use, the coolant enters the fluid channel 222 through the liquid inlet 225 and flows along the liquid flow path, and the gas enters the fluid channel 222 through the air inlet 223 and flows along the gas flow path. During the gas flow, heat is exchanged with the coolant to cool the gas. The cooled gas is discharged through the air outlet 224, and the coolant after heat exchange falls onto the first bottom wall 22221, wherein the coolant falling on the first part 22221a is blocked by the blocking structure 227. Under the guidance of the blocking structure 227, the coolant on the first bottom wall 22221 falls along the second part 22221b to the third part 22221c and flows through the third part 22221c to the position of the liquid outlet 226 of the second bottom wall 22222, so as to be discharged through the liquid outlet 226.

[0144] It should be understood that the first part 22221a is a structure formed by the shell 221 arching from its outer surface toward the inside of the fluid channel 222. When the condenser 22 is installed on the drum assembly 10 of the clothing processing device 100, the position corresponding to the first part 22221a can adapt to the structure of the outer peripheral surface of the drum assembly 10, thereby realizing the adaptive installation of the condenser 22 and the drum assembly 10 and improving the overall structural compactness.

[0145] In addition, the first part 22221a, the second part 22221b and the third part 22221c are arranged in a stepped structure, and the third part 22221c is arranged lower than the first part 22221a, wherein the second part 22221b is vertically connected to the first part 22221a, and the second part 22221b is also vertically connected to the third part 22221c, and the third part 22221c is inclined along the length direction of the fluid channel 222, and the lowest end of the third part 22221c is connected to the second bottom wall 22222. By setting the first part 22221a, the second part 22221b and the third part 22221c, the cooling liquid falling on the first bottom wall 22221 can flow along the liquid flow path, reducing the situation of flowing out with the gas.

[0146] In some embodiments of the present application, as shown in Figure 9, the distance between the central axis a of the air outlet 224 and the first side wall 2223 is L1, and the distance between the central axis a of the air outlet 224 and the second side wall 2226 is L2, where L2>L1, and a blocking structure 227 is provided on the first side wall 2223.

[0147] Specifically, a blocking structure 227 is provided on the first top wall 22211 of the top wall 2221, a blocking structure 227 is provided on the first portion 22221a of the first bottom wall 22221 (the first portion 22221a is connected to the first side wall 2223), and a blocking structure 227 is provided on the first side wall 2223. The air outlet 224 has a central axis a. Along the direction from the first side wall 2223 to the second side wall 2226, the distance between the central axis a and the first side wall 2223 is L1, and the distance between the central axis a and the second side wall 2226 is L2. By setting L2 to be greater than L1, the air outlet 224 is positioned closer to the side of the first side wall 2223.

[0148] By providing a blocking structure 227 on the first top wall 22211, the first side wall 2223 and the first part 22221a of the first bottom wall 22221, the blocking structure 227 is used to effectively block the coolant on the gas flow path, further reducing the flow of coolant to the air outlet 224.

[0149] In some embodiments of the present application, as shown in Figures 11 to 13, the blocking structure 227 provided on the first top wall 22211 or the second top wall 22212, the blocking structure 227 provided on the first side wall 2223 and the blocking structure 227 provided on the first part 22221a are connected in sequence.

[0150] Specifically, in the present application, the blocking structure 227 is a convex rib structure provided on the wall of the fluid channel 222, the blocking structure 227 provided on the first top wall 22211 or the second top wall 22212 is a first rib 2271, the blocking structure 227 provided on the first side wall 2223 is a second rib 2272, and the blocking structure 227 provided on the first part 22221a is a third rib 2273, wherein the first rib 2271, the second rib 2272 and the third rib 2273 are connected in sequence.

[0151] By setting the blocking structures 227 on the three walls, the blocking structures 227 on the three walls can form an integrated structure, which can improve the blocking effect and further reduce the situation where the coolant flows to the liquid outlet 226.

[0152] It should be pointed out that in the present application, the protruding height of the rib structure is in the range of 4mm to 10mm, and the specific values ​​can be 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, and 10mm.

[0153] In addition, the connection method between the rib structure and the corresponding wall includes but is not limited to bonding, welding or integral molding.

[0154] In some embodiments of the present application, the gas outlet 224 has a projected area on the bottom wall 2222 , and the liquid outlet 226 and the third portion 22221 c are both located outside the projected area.

[0155] Specifically, the top wall 2221 and bottom wall 2222 of the fluid channel 222 are disposed opposite each other, the third top wall 22213 and the second bottom wall 22222 are both located on the same side of the blocking structure 227 and are disposed opposite each other, the gas outlet 224 is disposed on the third top wall 22213, and the liquid outlet 226 is disposed on the second bottom wall 22222. Gas in the gas flow path is discharged from the condenser 22 through the gas outlet 224, and coolant in the liquid flow path is discharged from the condenser 22 through the liquid outlet 226.

[0156] By arranging the air outlet 224, the liquid outlet 226 and the third part 22221c of the first bottom wall 22221, the air outlet 224 avoids being directly above the liquid outlet 226 and the third part 22221c, so as to reduce the situation in which the coolant at the liquid outlet 226 and the third part 22221c is also extracted when the air after heat exchange is extracted through the air outlet 224, thereby further reducing the situation in which the coolant is discharged through the air outlet 224.

[0157] In some embodiments of the present application, as shown in Figures 12 and 13, the condenser 22 also includes a guide plate 229, which is arranged in the fluid channel 222. The guide plate 229 is located below the liquid inlet 225 and is arranged facing the liquid inlet 225, and the air inlet 223 is arranged facing the guide plate 229.

[0158] Specifically, in the present application, a guide plate 229 is disposed within the fluid channel 222 and connected to the first sidewall 2223 of the fluid channel 222. The guide plate 229 is disposed facing the liquid inlet 225. When the condenser 22 is in use, coolant enters the fluid channel 222 through the liquid inlet 225, falls onto the guide plate 229, and then falls along the edge of the guide plate 229, thereby forming a water curtain structure. The air inlet 223 is disposed on the first end wall 2224 of the fluid channel 222. After entering the fluid channel 222 through the air inlet 223, the gas needs to pass through the water curtain. During the process of passing through the water curtain, the gas exchanges heat with the coolant to achieve cooling. The cooled gas then flows along the gas flow path to the air outlet 224 and is discharged. The coolant, after heat exchange, also flows along the liquid flow path to the liquid outlet 226 and is discharged through the liquid outlet 226.

[0159] By providing the guide plate 229, the heat exchange area between the coolant and the gas is increased, thereby improving the heat exchange effect on the gas.

[0160] In some embodiments of the present application, as shown in Figures 12 and 13, there are multiple guide plates 229, and the multiple guide plates 229 are arranged at intervals along the direction from the top wall 2221 to the bottom wall 2222. Among the two adjacent guide plates 229, the guide plate 229 located above has a projection on the guide plate 229 located below, and the area of ​​the projection is smaller than the area of ​​the guide plate 229 located below.

[0161] By providing a plurality of guide plates 229 and configuring the guide plates 229, the coolant can be dispersed layer by layer after passing through each guide plate 229 from top to bottom, thereby increasing the coverage area of ​​the water curtain, and further increasing the heat exchange area between the coolant and the gas, thereby further improving the heat exchange effect on the gas.

[0162] In some embodiments of the present application, as shown in FIG. 12 and FIG. 13 , a water baffle 228 is further included. The water baffle 228 is disposed on the first top wall 22211 , and the water baffle 228 is disposed between the liquid inlet 225 and the blocking structure 227 .

[0163] Specifically, the water baffle 228 and the liquid inlet 225 are both arranged on the first top wall 22211 of the top wall 2221, and the water baffle 228 is arranged between the blocking structure 227 and the liquid inlet 225. At the same time, the water baffle 228 is arranged at the edge of the liquid inlet 225, and the plate surface of the water baffle 228 is arranged to be inclined toward the liquid inlet 225. In the present application, the gas flow path and the liquid flow path are arranged to intersect. When the coolant enters the fluid channel 222 through the liquid inlet 225, the gas will drive the coolant to flow along the first top wall 22211 toward the liquid outlet 226. By providing the water baffle 228 and blocking the coolant flowing along the first top wall 22211, the coolant can flow along the liquid flow path when entering the fluid channel 222 through the liquid inlet 225, so that it can fully contact with the gas, thereby improving the heat exchange effect on the gas.

[0164] In some embodiments of the present application, as shown in Figures 8 to 11, the condenser 22 is a split structure, including a cover plate 2211 and a shell body 2212. The water baffle 228 and the guide plate 229 are both provided on the shell body 2212. The shell body 2212 has an opening. The cover plate 2211 is connected to the shell body 2212 and closes the opening of the shell body 2212, thereby forming a fluid channel 222. The condenser 22 is configured as a split structure so that it can be processed and manufactured by injection molding, thereby effectively reducing the manufacturing cost.

[0165] In some embodiments of the present application, the matching method between the cover plate 2211 and the shell body 2212 includes but is not limited to welding, riveting, bonding, screw connection or clamping.

[0166] In some embodiments of the present application, a connection portion is provided on the condenser 22 , and the number of the connection portion is at least one.

[0167] Specifically, when the condenser 22 is used in the laundry processing apparatus 100, the condenser 22 is fixed to the outer drum 11 of the drum assembly 10 via the connecting portion. The provision of the connecting portion facilitates assembly of the condenser 22, thereby effectively improving assembly efficiency and reducing manufacturing costs.

[0168] It should be noted that, in the present application, the connection portion includes but is not limited to a buckle or a connection hole, etc. For example, if the connection portion is a connection hole, when the condenser 22 is connected and fixed to the outer cylinder 11 of the cylinder assembly 10, a screw can be passed through the connection hole to connect and fix the condenser 22 to the outer cylinder 11.

[0169] The above description is merely a preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
