[0063] The following will be combined with the accompanying drawings to clearly and completely describe some embodiments of the present disclosure. Obviously, the embodiments described are only some embodiments of the present disclosure, rather than all embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present disclosure.

[0064] Unless the context requires otherwise, throughout the specification and claims, the term "comprise" and its other forms, such as the third person singular form "comprises" and the present participle form "comprising", are to be interpreted as open and inclusive, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example", "specific example" or "some examples" are intended to indicate that the particular features, structures, materials or characteristics associated with the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the particular features, structures, materials or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

[0065] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present disclosure, unless otherwise specified, "plurality" means two or more.

[0066] When describing some embodiments, the expressions "coupled" and "connected" and their derivatives may be used. The term "connected" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. The term "coupled" indicates that two or more components are in direct physical or electrical contact. The term "coupled" or "communicatively coupled" may also refer to two or more components that are not in direct contact with each other, but still cooperate or interact with each other. The embodiments disclosed herein are not necessarily limited to the contents of this document.

[0067] “At least one of A, B and C” has the same meaning as “at least one of A, B or C” and both include the following combinations of A, B and C: A only, B only, C only, the combination of A and B, the combination of A and C, the combination of B and C, and the combination of A, B and C.

[0068] “A and / or B” includes the following three combinations: A only, B only, and a combination of A and B.

[0069] The use of "adapted to" or "configured to" herein is intended to be open and inclusive language that does not exclude devices adapted or configured to perform additional tasks or steps.

[0070] As used herein, "about," "substantially," or "approximately" includes the stated value and an average value that is within an acceptable range of deviation from the particular value as determined by one of ordinary skill in the art taking into account the measurements in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system).

[0071] As used herein, "parallel", "perpendicular", and "equal" include the situations described and situations similar to the situations described, and the range of the similar situations is within an acceptable deviation range, wherein the acceptable deviation range is as determined by a person of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the specific quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, wherein the acceptable deviation range of approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, wherein the acceptable deviation range of approximate perpendicularity can also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, wherein the acceptable deviation range of approximate equality can be, for example, that the difference between the two equals is less than or equal to 5% of either one.

[0072] Typically, a clothing processing device includes a heat pump system housed within a drying duct. This duct communicates with the clothing receiving chamber of the clothing processing device, forming an air circulation space. When drying clothing, moist air in the chamber flows through the air outlet of the drum assembly into the drying duct. After condensation and heating by the heat pump system, the air becomes hot, dry air, which then flows through the drum assembly's air inlet back into the chamber, where it circulates to dry the clothing.

[0073] However, due to the unreasonable structural setting of the drying duct in the current clothing processing equipment, the air inlet of the drying duct is almost perpendicular to the air duct between the heat pump system, so that the air cannot flow smoothly to the heat pump system after entering the drying duct, which in turn reduces the heat exchange efficiency of the evaporator and condenser and increases the drying time of the clothes.

[0074] Furthermore, when the current clothes processing equipment is drying clothes, foreign matter in the air (such as hair scraps in the clothes receiving chamber) will enter the heat pump system through the drying air duct, thereby affecting the operation of the heat pump system.

[0075] The present disclosure provides a laundry processing device 100. A filter device is provided within the drying duct of the laundry processing device 100 to filter foreign matter from the air, thereby ensuring the proper functioning of the heat pump system. Furthermore, an air guide structure and an air distributor are provided within the drying duct to smoothly direct air from the laundry compartment to the heat pump system, thereby improving the heat exchange efficiency of the evaporator and condenser.

[0076] 1A , a laundry processing apparatus 100 includes a housing 10, which forms an outer shell of the laundry processing apparatus 10. The housing 10 has a storage space that can accommodate internal components of the laundry processing apparatus 100, such as a drum assembly, circuit structure, air duct structure, drive mechanism, and drainage structure, to protect these components.

[0077] For example, the box body 10 includes a base 11, box side walls 12, and a box top wall 13. The box side walls 12 are arranged around the base 11, and the box top wall 13 is covered on the box side walls 12, thereby forming the accommodating space.

[0078] In some embodiments, the housing 10 further includes a loading port 101. The loading port 101 is located on the front sidewall 12 of the housing 10 and communicates with the storage space of the housing 10. Clothes enter the housing 10 through the loading port 101, where they are then washed or dried by the laundry processing device 100. A door is provided on the front side of the housing 10, configured to open and close the loading port 101, and thereby the storage space of the housing 10.

[0079] It should be noted that FIG. 1A does not show the side wall 12 of the cabinet located at the front of the clothes processing device 10 and the door for covering the front opening.

[0080] 1B to 5 , the laundry processing apparatus 100 further includes a drum assembly 20 disposed within the housing 10. The drum assembly 20 has a laundry receiving chamber 21 for receiving laundry. The laundry receiving chamber 21 includes a chamber body and a first air outlet 211 and a first air inlet 212 communicating with the chamber body.

[0081] When the laundry processing device 100 is processing laundry, the door covers the loading port 101, thereby enclosing the laundry chamber 21. For example, when the laundry processing device 100 is washing laundry, the door seals the loading port 101, making the laundry chamber 21 a sealed space during the washing process and preventing liquid from leaking out and affecting the washing effect. The door can also be equipped with a glass door to facilitate observation of the laundry processing progress.

[0082] In some embodiments, the drum assembly 20 includes an outer drum 22 and an inner drum 23. The outer drum 22 is disposed within the housing 10, and the inner drum 23 is disposed within the outer drum 22. The inner drum 23 can rotate relative to the outer drum 22. The clothing receiving chamber 21 is disposed within the inner drum 23. For example, when clothing is placed in the clothing receiving chamber 21 for washing, the inner drum 23 rotates relative to the outer drum 22, causing the clothing to rotate and tumble for washing.

[0083] The openings of the outer drum 22 and the inner drum 23 are arranged opposite each other, and are also arranged opposite the loading port 101. Therefore, clothes can enter the clothes receiving chamber 21 from the loading port 101, the openings of the outer drum 22 and the openings of the inner drum 23 in sequence.

[0084] The sidewall of the inner drum 23 is provided with a plurality of spaced-apart communication holes 231 for connecting the laundry accommodating cavity 21 of the inner drum 23 and the space between the inner drum 23 and the outer drum 22. The first air outlet 211 is provided at the rear side of the drum assembly 20 and communicates with the outer drum 22, while the first air inlet 212 is provided at the front side of the drum assembly 20 and communicates with the inner drum 23. The front side of the drum assembly 20 is the side from which a user operates the laundry processing apparatus 100.

[0085] In some embodiments, the laundry processing apparatus 100 further includes a wastewater outlet. The wastewater outlet is disposed at the bottom of the drum assembly 20 and is configured to discharge wastewater generated during the laundry processing process. For example, the wastewater outlet is disposed at the bottom of the outer drum 22. During the laundry washing process, the inner drum 23 discharges wash water into the outer drum 22 through the communication hole 231. The wash water then exits the laundry processing apparatus 100 through the wastewater outlet and other drainage structures (such as a drainpipe, etc.) connected to the outer drum 22.

[0086] In some embodiments, the laundry processing apparatus 100 further includes a driving device, which is disposed within the housing 10. For example, the driving device is disposed outside the outer drum 22, and an output end of the driving device extends into the outer drum 22 and is transmission-connected to the inner drum 23 to drive the inner drum 23 to rotate relative to the outer drum 22, thereby achieving flipping of the laundry to improve the laundry processing effect of the laundry processing apparatus 100.

[0087] Referring to Figures 6 to 8 , the laundry processing apparatus 100 further includes a drying duct 30. It will be appreciated that the drying duct 30 is sealed. The drying duct 30 is disposed at the top of the drum assembly 20. One end of the drying duct 30 communicates with the first air outlet 211, and the other end communicates with the first air inlet 212. The dotted arrows in Figure 8 indicate the direction of air flow within the drying duct 30.

[0088] For example, the air in the clothing receiving chamber 21 flows into the drying duct 30 through the first air outlet 211. The drying duct 30 dehumidifies and heats the air to produce high-temperature dry air. The high-temperature dry air then enters the clothing receiving chamber 21 through the first air inlet 212, thereby drying the clothes in the clothing receiving chamber 21.

[0089] For example, the drying duct 30 includes a second air inlet 301 and a second air outlet 302. The second air inlet 301 is connected to the first air outlet 211, and the second air outlet 302 is connected to the first air inlet 212. Air in the clothing receiving chamber 21 can be discharged from the clothing receiving chamber through the first air outlet 211, flow into the drying duct 30 through the second air inlet 301, and then flow out of the drying duct 30 through the second air outlet 302 and into the clothing receiving chamber 21 through the first air inlet 212.

[0090] In some embodiments, the laundry processing apparatus 100 includes a duct member 3. The duct member 3 is disposed on top of the drum assembly 20 and is located between the drum assembly 20 and the top wall 13 of the housing. The duct member 3 includes a first cover plate 31 (i.e., a cover plate) and a support plate 80. The first cover plate 31 covers the top of the support plate 80, and a drying duct 30 is defined between the first cover plate 31 and the support plate 80. The first cover plate 31 constitutes at least a portion of the top wall of the drying duct 30, and the support plate 80 constitutes at least a portion of the bottom wall of the drying duct 30.

[0091] In some embodiments, the support plate 80 is arranged horizontally, and at least one side edge of the support plate 80 is fixedly connected to the box body 10 .

[0092] By covering the first cover plate 31 with the support plate 80, the sealing performance of the air duct member 3 can be increased to seal the drying air duct 30, so that the drying air duct 30 can be connected to the clothing holding chamber 21 through the second air inlet 301 and the second air outlet 302, thereby ensuring the drying effect of the clothing processing device 100.

[0093] 9 and 10 , the laundry processing apparatus 100 further includes a heat pump system 40 , which is disposed in the drying air duct 30 . The heat pump system 40 is configured to dehumidify and heat the air in the laundry receiving chamber 21 to form high-temperature dry air.

[0094] The heat pump system 40 includes an evaporator 41 and a condenser 42. The evaporator 41 and condenser 42 are disposed within the drying duct 30 and arranged sequentially along the air flow direction S within the drying duct 30. The evaporator 41 is configured to condense moisture from the air drawn out of the first air outlet 211. The condenser 42 is configured to heat the air condensed by the evaporator 41 and direct the heated air into the clothing receiving chamber 21 to dry the clothing within the clothing receiving chamber 21.

[0095] For example, the heat pump system 40 dries clothes as follows: the relatively moist, low-temperature air flowing out of the drum assembly 20 first passes through the evaporator 41 for heat exchange, which lowers the air temperature and condenses the moisture, turning it into dry, low-temperature air. The dry, low-temperature air then passes through the condenser 42 for heat exchange, raising its temperature to become dry, high-temperature air. The dry, high-temperature air then enters the drum assembly 20, exchanges heat with the moist clothes, and circulates continuously to dry the clothes.

[0096] In some embodiments, both the evaporator 41 and the condenser 42 are constructed by inserting a copper tube through a plurality of fins spaced in the same direction. The fins and the copper tubes form the heat exchanger components of the evaporator 41 and the condenser 42. Refrigerant flows through the copper tubes to absorb or release heat. The fins increase the contact area between the copper tubes and the outside world, thereby improving heat exchange efficiency.

[0097] As can be seen, the larger the heat exchange components of the evaporator 41 and condenser 42, the more complete their contact with the air, resulting in higher heat exchange efficiency. In other words, the larger the space accommodating the heat pump system 40, the better the drying effect of the laundry processing device 100. Since the space between the top of the drum assembly 20 and the housing 10 is larger than the space between the bottom of the drum assembly 20 and the housing 10, positioning the drying duct 30 between the top of the drum assembly 20 and the housing 10 allows for a larger heat pump system 40, thereby improving the heat exchange efficiency of the heat pump system 40 and the drying effect of the laundry processing device 100.

[0098] Furthermore, in order to better utilize the space at the top of the cylinder assembly 20 , the evaporator 41 and the condenser 42 are spaced apart between the second air inlet 301 and the second air outlet 302 along the left-right direction.

[0099] 9 and 10 , the laundry processing apparatus 100 further includes a first air duct 32 and a second air duct 33, which are located at opposite ends of the drying duct 30. The first air duct 32 communicates with the first air outlet 211, allowing moist air within the laundry receiving chamber 21 to enter the drying duct 30 through the second air duct 33. The second air duct 33 communicates with the first air inlet 212, allowing hot, dry air within the drying duct 30 to be introduced into the laundry receiving chamber 21 through the first air duct 32.

[0100] For example, one end of the first air duct 32 is connected to the first air outlet 211, and the other end of the first air duct 32 is connected to the second air inlet 301. One end of the second air duct 33 is connected to the second air outlet 302, and the other end of the second air duct 33 is connected to the first air inlet 212.

[0101] It is understood that the clothing processing device 100 provided in the present disclosure can be a clothes dryer that is only used to dry clothes. The clothing processing device 100 can also be a washing and drying machine that can wash and dry clothes. For example, the washing and drying machine washes clothes and then dries them, or only washes and dries clothes. Since the clothing processing device 100 achieves the drying function through a heat pump system, the clothing processing device is a heat pump dryer or a heat pump washing and drying machine.

[0102] 11 to 15 , the laundry processing apparatus 100 further includes a filter device 50. The filter device 50 is disposed within the drying air duct 30 and is configured to filter foreign matter from the air directed out of the first air outlet 211. The filter device 50 is located on a side of the evaporator 41 near the first air outlet 211. Specifically, the filter device 50 is located between the second air inlet 301 and the evaporator 41.

[0103] It should be noted that the filter device 50 may be partially or entirely located within the drying duct 30, without specific limitation. When the filter device 50 is partially located within the drying duct 30, the portion of the filter device 50 located within the drying duct 30 performs a filtering function, while the portion located outside the drying duct 30 facilitates user access.

[0104] It is understood that when the filter device 50 is disposed between the first air outlet 211 and the evaporator 41, the air discharged from the first air outlet 211 will be filtered by the filter device 50 before being introduced into the evaporator 41. Therefore, even if foreign matter in the clothing receiving chamber 21 is discharged from the first air outlet 211, it will be filtered out by the filter device 50 before entering the evaporator 41, thereby preventing the foreign matter from entering the evaporator 41 and condenser 42 and affecting the normal operation of the heat pump system 40.

[0105] In some embodiments, the filter device 50 can be installed in the housing 10 in a pull-out manner to facilitate cleaning of foreign matter accumulated on the filter device 50 , thereby ensuring the filtering effect of the filter device 50 and further ensuring the heat exchange efficiency of the evaporator 41 and the condenser 42 .

[0106] 14 to 17 , the duct member 3 further includes a mounting slot 34 . The mounting slot 34 is disposed within the drying duct 30 . The mounting slot 34 has a first opening 341 , which is located at the front side of the mounting slot 34 and communicates with the mounting slot 34 . The filter device 50 is retractably disposed within the mounting slot 34 .

[0107] The mounting slot 34 extends along the width of the drying duct 30 (i.e., the front-to-back direction of the drying duct 30 or a direction perpendicular to the air flow direction S). In this case, the length of the mounting slot 34 coincides with the width of the drying duct 30. The vertical height of the mounting slot 34 can be set to be lower than the vertical height of the drying duct 30, thereby avoiding occupying too much space in the drying duct 30 and affecting air flow. The width of the first opening 341 of the mounting slot 34 can be equal to the width of the structure at the bottom of the filter device 50 mounted at the first opening 341, thereby allowing the filter device 50 to be snapped into place within the mounting slot 34 and securely fixed.

[0108] The mounting slot 34 can extend from one sidewall (e.g., the front sidewall) of the drying duct 30 to the other opposite sidewall (e.g., the rear sidewall). When the filter device 50 is installed in the mounting slot 34, the drying duct 30 is divided into two sections arranged along the direction of air flow. Air from the portion of the drying duct 30 located on one side (e.g., the left side) of the filter device 50 must pass through the filter device 50 before being introduced into the portion of the drying duct 30 located on the other side (e.g., the right side) of the filter device, thereby enabling the filter device 50 to fully filter the air entering the heat pump system 40.

[0109] The first opening 341 of the mounting groove 34 can have a certain depth to communicate with the mounting groove 34, thereby allowing the filter device 50 to be installed in the mounting groove 34 through the first opening 341 and to be removed from the first opening 341. The shape of the first opening 341 can match the shape and size of the structure of the portion of the filter device 50 that is installed at the first opening 341, thereby allowing the filter device 50 to be tightly combined with the first opening 341 when installed, thereby sealing the first opening 341 and ensuring the airtightness of the drying duct 30.

[0110] 18 , the filter device 50 includes a mounting portion 51 and a filter portion 52. The mounting portion 51 and the filter portion 52 are arranged along the length (i.e., the front-to-back direction) of the filter device 50. The mounting portion 51 is located at the front of the filter device 50 to facilitate installation of the filter device 50 in the mounting slot 34 through the first opening 341. The filter portion 52 is located within the drying air duct 30 to filter foreign matter.

[0111] The mounting portion 51 and the filter portion 52 can be integrally formed to ensure the integrity and durability of the filter device 50. The mounting portion 51 is at least partially exposed outside the first opening 341, and further, at least partially exposed outside the sidewall of the drying duct 30, allowing a user to grasp the portion of the mounting portion 51 exposed outside the first opening 341 to remove and place the filter device 50.

[0112] When the filter device 50 is installed in the drying air duct 30 , the filter portion 52 is entirely located inside the drying air duct 30 , so that the filter portion 52 can fully contact the air in the drying air duct 30 , thereby improving the air filtering effect.

[0113] 19 to 22 , the filter unit 52 includes a filter frame 521 and a filter screen 522. The filter frame 521 has a hollow area 5211, and the filter screen 522 is disposed in the hollow area 5211 (e.g., on the right side of the filter device 50). The shape and size of the hollow area 5211 match those of the filter screen 522, allowing the filter screen 522 to cover the hollow area 5211.

[0114] The filter rack 521 is at least partially disposed within the drying duct 30. The height of the filter rack 521 can be aligned with the height of the drying duct 30. The length of the filter rack 521 can be equal to the width of the drying duct 30 at the corresponding position (i.e., the length in the front-to-back direction), thereby enabling the filter rack 521 and the filter screen 522 thereon to separate the drying duct 30 into two parts along the direction of air flow. At this time, air on one side of the filter rack 521 (e.g., the left side) can pass through the filter screen 522 on the filter rack 521 before passing through the filter device 50, thereby enabling the air to be fully filtered.

[0115] In some embodiments, the filter 522 is provided with a plurality of filter holes arranged at intervals, the diameter of the filter holes being smaller than the diameter of the foreign matter (such as hair) to be filtered. Thus, when the air containing foreign matter passes through the filter device 50, the foreign matter in the air is blocked by the filter 522. In this way, the air flowing through the drying duct 30 is filtered.

[0116] Referring to Figure 22 , a second slot 5212 is provided on one side of the filter frame 521 near the first air outlet 211. The second slot 5212 is configured to collect foreign matter blocked by the filter 522. The opening of the second slot 5212 faces the top wall of the drying duct 30 and is lower than the top of the filter 522. After foreign matter is blocked by the filter 522, some will fall into the second slot 5212, while the rest will adhere to the filter 522 and, after accumulating to a certain amount, fall out of the second slot 5212.

[0117] The second slot 5212 prevents foreign matter filtered out by the filter 522 from being stored in the second slot 5212, thereby preventing the foreign matter from being scattered in the drying duct 30 and being difficult to collect, or from flowing back into the clothing receiving chamber 21 and affecting the clothing treatment effect. When the amount of foreign matter in the second slot 5212 reaches a certain level, the user can remove the filter device 50 and clean out the foreign matter in the second slot 5212 to ensure the filtering effect of the filter device 50.

[0118] In some embodiments, the filter frame 521 further includes a bottom wall 5213 and side walls 5214, which can also be considered the bottom wall and side walls of the second groove 5212. The bottom wall 5213 is disposed at the bottom of the filter frame 521 and below the filter screen 522. The side wall 5214 is disposed on a side of the bottom wall 5213 away from the filter screen 522 and opposite to the filter screen 522. The bottom of the side wall 5214 is flush with the bottom wall 5213, and the top of the side wall 5214 is lower than the top of the filter screen 522. That is, the height of the side wall 5214 in the vertical direction is lower than the height of the filter screen 522 in the vertical direction. This allows the top of the second groove 5212 to be lower than the top of the filter screen 522, thereby avoiding affecting the ventilation effect of the filter device 50.

[0119] In some embodiments, referring to FIG. 22 , the filter frame 521 further includes a filter plate 5215 , which is hollowed out to ensure ventilation of the filter device 50. The filter screen 522 can be disposed on one side (e.g., the right side) of the filter plate 5215 . The bottom wall 5213 and side wall 5214 are located on the side of the filter plate 5215 near the first air outlet 211 (i.e., the left side of the filter frame 521 ), thereby enclosing the filter plate 5215 , the bottom wall 5213 , and the side wall 5214 to form a second groove 5212 .

[0120] Referring to Figures 16 and 17 , the drying duct 30 includes an expansion duct 35 and a first chamber 36, which are arranged sequentially along the direction of air flow within the drying duct 30. One end of the expansion duct 35 communicates with the first air outlet 211, the other end of the expansion duct 35 communicates with one end of the first chamber 36, and the other end of the first chamber 36 communicates with the first air inlet 212. The expansion duct 35 is configured to direct air into the first chamber 36. The first chamber 36 is configured to accommodate the evaporator 41 and the condenser 42. For example, the first air duct 32 communicates with the expansion duct 35, and the first chamber 36 communicates with the second air duct 33. Consequently, air discharged from the first air outlet 211 passes through the second air duct 33, the expansion duct 35, the first chamber 36, the first air duct 32, and the first air inlet 212, and enters the clothing receiving chamber 21.

[0121] It should be noted that the second air inlet 301 is located at one end of the air expansion duct 35, and the second air outlet 302 is located at one end of the first cavity 36. That is, the air expansion duct 35 includes the second air inlet 301, and the first cavity 36 includes the second air outlet 302.

[0122] Because the area of ​​the air inlet surface of the first chamber 36 is larger than that of the second air inlet 301, the width of the expansion duct 35 increases along the direction of air flow. For example, the cross-sectional area of ​​the expansion duct 35 perpendicular to the direction of air flow increases. This increases the outlet area of ​​the expansion duct 35 relative to the area of ​​the second air inlet 301, thereby increasing the efficiency of air circulation within the expansion duct 35 and smoothly directing air into the first chamber 36. This improves the drying efficiency of the laundry processing apparatus 100 and shortens the drying time of the laundry.

[0123] When the drying duct 30 includes the expansion duct 35 and the first chamber 36, the filter device 50 is disposed between the expansion duct 35 and the first chamber 36. Air in the expansion duct 35 passes through the filter device 50 and enters the first chamber 36. At this time, one side of the filter device 50 communicates with the expansion duct 35 to receive air discharged from the expansion duct 35, and the other side of the filter device 50 communicates with the first chamber 36, allowing the air filtered by the filter device 50 to enter the first chamber 36.

[0124] 20 and 21 , the hollow region 5211 of the filter frame 521 further includes a plurality of sub-hollow regions 52111, which are arranged at intervals along the length of the filter frame 521. The filter frame 521 further includes a plurality of dividers 5216, which are arranged at intervals along the length of the filter frame 521 in the hollow region 5211, thereby dividing the hollow region 5211 into the plurality of sub-hollow regions 52111.

[0125] 23 and 24 , the duct member 3 further includes a plurality of air distribution plates 351 , which are disposed within the expansion duct 35 and extend along the direction of air flow. For example, the air distribution plates 351 gradually bend and extend in the direction from the second air inlet 301 toward the heat pump system 40 to form an arc-shaped structure. The plurality of air distribution plates 351 divide the expansion duct 35 into a plurality of sub-ducts, with different sub-ducts directing air into different sub-hollow regions 52111 . For example, the air distribution plates 351 extend from one side of the expansion duct 35 to the other. The width of the sub-ducts can be determined based on the air flow rate, so that the air flow rates directed into the sub-hollow regions 52111 by different sub-ducts are similar, thereby ensuring the filtering effect of the filter device 50 and allowing the air to enter the first chamber 36 evenly. This improves the heat exchange efficiency of the evaporator 41 and the condenser 42 and enhances the heat exchange effect.

[0126] Multiple air distribution plates 351 are spaced apart along the axis of the second air inlet 301 (i.e., in the front-to-back direction of the air expansion duct 35). The air distribution plates 351 can also be staggered in the left-right direction to avoid mutual interference. Providing multiple air distribution plates 351 can further enhance the air diversion effect.

[0127] It is understandable that the number of air distribution plates 351 can be set according to actual needs, and can be multiple or one, and the present disclosure does not impose any restrictions on this.

[0128] The extending direction of the partition 5216 is consistent with the extending direction of the air distribution plate 351. One end of the partition 5216 is connected to the air distribution plate 351, and the other end of the partition 5216 abuts against the filter 522. Therefore, after passing through the air distribution plate 351 and the partition 5216, the air is filtered by the filter 522 covered by the different sub-hollow areas 52111, thereby fully utilizing the filtration rate of the filter 522 and improving the air filtering effect.

[0129] In some embodiments, the partition 5216 divides the interior space of the filter frame 521 into equal parts along the length of the filter frame 521. The air distributor 351 divides the interior space of the air expansion duct 35 into equal parts, thereby allowing air to flow evenly from the air expansion duct 35 into the first chamber 36, thereby increasing the uniformity of air entering the first chamber 36.

[0130] The two sides (e.g., the left and right sides) of the filter frame 521 are respectively disposed in contact with the air expansion duct 35 and the first chamber 36, and the length direction of the filter frame 521 is aligned with the width direction of the side of the first chamber 36 adjacent to the air expansion duct 35. The filter frame 521 can be disposed parallel to the side of the first chamber 36 adjacent to the air expansion duct 35. By disposing the filter frame 521 on one side (e.g., the left side) of the first chamber 36 and aligning the length direction of the filter frame 521 with the width direction of the side of the first chamber 36, the space at the top of the cartridge assembly 20 can be fully utilized.

[0131] For example, a second opening 5201 and a third opening 5202 are respectively provided on opposite sides of the filter frame 521. The second opening 5201 and the third opening 5202 are interconnected, with the second opening 5201 communicating with the second air inlet 301, and the third opening 5202 communicating with the first cavity 36, thereby allowing air to flow into the first cavity 36 through the second opening 5201 and the third opening 5202. The filter screen 522 is provided at the third opening 5202 to filter the air flowing into the first cavity 36.

[0132] 15 to 17 , the first air duct 32 has an air outlet end 331. The air outlet end 331 is located at the end of the first air duct 32 away from the first air outlet 211 (i.e., the end of the first air duct 32 connected to the second air inlet 301 is located at the top rear side of the barrel assembly 20), that is, the second air inlet 301 is located at the top rear side of the barrel assembly 20. The filter frame 521 is arranged on one side of the air outlet end 331 (such as the right side). Therefore, in some embodiments, the air expansion duct 35 is arranged in an arc shape. For example, the air expansion duct 35 extends in an arc shape from the second air inlet 301 toward the first cavity 36.

[0133] It is understood that the air outlet 331 faces the front of the drying duct 30, and the air inlet of the first chamber 36 faces the left side of the drying duct 30. Therefore, after entering the drying duct 30 through the second air inlet 301, air may first flow along the side walls (such as the left wall) of the expansion duct 35 to the front inner wall of the expansion duct 35 before turning to the heat pump system 40. To prevent the air from being obstructed by the front inner wall, which would reduce its velocity and flow rate, the expansion duct 35 needs to be configured in an arc shape to ensure smooth air flow from the air outlet 331 to the first chamber 36.

[0134] In some embodiments, referring to Figures 25 and 54, the duct member 3 further includes an air guide structure 39. The air guide structure 39 is provided in the air expansion duct 35 and is located between the second air inlet 301 and the heat pump system 40. The air guide structure 39 is configured to guide air to the heat pump system 40. The end of the air guide structure 39 away from the second air inlet 301 is inclined toward the heat pump system 40, so that the air entering the drying duct 30 from the second air inlet 301 can gradually turn along the air guide structure 39, avoiding the air from hitting the front inner wall and dispersing everywhere. In addition, the air guide structure 39 cooperates with the air distribution plate 351 to further guide the air to the heat pump system, thereby accelerating the heat exchange between the air and the heat pump system 40, thereby further improving the drying efficiency of the clothing processing device 100.

[0135] In some embodiments, the air guide structure 39 serves as a side wall of the air expansion duct 35. For example, the edge of one side (e.g., the left side) of the first cover plate 31 adjacent to the second air inlet 301 covers the top of the support plate 80 to form a side wall of the air expansion duct 35, which constitutes the air guide structure 39.

[0136] 23 to 27 , the drying duct 30 further includes an air guide 352, which is disposed on a side of the filter device 50 near the first air outlet 211. Air exiting the first air outlet 211 enters the filter device 50 through the air guide 352. Specifically, the air expansion duct 35 is provided at one end near the filter device 50 with the air guide 352, and air within the air expansion duct 35 enters the filter device 50 through the air guide 352.

[0137] 27 , the bottom of the air guide 352 is higher than the top of the second slot 5212, that is, the bottom of the air guide 352 is located above the sidewall of the second slot 5212. This allows the air flowing out of the air guide 352 to flow from the top of the second slot 5212 toward the filter 522, preventing the air from flowing into the second slot 5212 and blowing up foreign matter within the second slot 5212. Furthermore, because the top of the second slot 5212 is lower than the air guide 352, when air from the filter device 50 flows back to the first air outlet 211, foreign matter in the second slot 5212 is less likely to flow back to the first air outlet 211 along with the air. This reduces the backflow of collected foreign matter and ensures the cleanliness of the clothing receiving chamber 21.

[0138] In some embodiments, the air guide port 352 can be an air guide port at one end of the air expansion duct 35 close to the filter device 50, that is, the air entering the air expansion duct 35 needs to pass through the air guide port 352 before it can enter the filter device 50 for filtration, that is, the air expansion duct 35 and the filter device 50 are connected through the air guide port 352.

[0139] In order to further reduce the backflow of foreign matter in the second groove 5212, in some embodiments, the air duct member 3 further includes a baffle 37. The baffle 37 is movably disposed at the air guide port 352. The baffle 37 is configured to open and close the air guide port 352.

[0140] For example, the flap 37 is disposed on a side of the air guide opening 352 that is close to the filter device 50. During the process of opening the air guide opening 352, the flap 37 moves toward the filter device 50. When air is not flowing in the drying duct 30, the flap 37 covers the air guide opening 352. When air is flowing in the drying duct 30, the air within the drying duct 30 drives the flap 37 to move, thereby opening the air guide opening 352.

[0141] It is understood that the shape and size of the baffle 37 can match the shape and size of the air duct 352, so that the baffle 37 can completely cover the air duct 352. The top of the baffle 37 can be connected to the top of the air duct 352, and the connection between the two can be a movable connection or a fixed connection. For example, when the baffle 37 and the air duct 352 are movably connected via a rotating shaft, the baffle 37 can rotate around the rotating shaft to open and close the air duct 352, and the baffle 37 can cover the air duct 352 by its own gravity. When the baffle 37 and the air duct 352 are fixedly connected, the baffle 37 can have a certain degree of elasticity, and the baffle 37 covers the air duct 352 in the initial state, moves to open the air duct 352 under the drive of wind, and re-closes the air duct 352 by its own elastic force when there is no wind.

[0142] It should be noted that when the baffle 37 is set at the air guide port 352, the baffle 37 can be connected to the air duct wall of the air expansion duct 35, or can be connected to the side of the filter device 50 close to the air expansion duct 35. The present disclosure does not limit this.

[0143] Referring to Figures 22 and 27 , the filter frame 521 further includes a top wall 5217, which is disposed at the top of the filter frame 521, i.e., at the top of the filter plate 5215. The top wall 5217 is disposed opposite the bottom of the second slot 5212, i.e., the top wall 5217 is disposed opposite the bottom wall 5213. The air guide 352 is formed between the sidewall 5214 and the top wall 5217. When the baffle 37 is connected to the filter device 50, the top of the baffle 37 can be connected to the top wall 5217, and in this case, the baffle 37 can be considered part of the filter device 50.

[0144] 27 , the duct member 3 further includes a retaining rib 353. The retaining rib 353 is disposed at the bottom of the air guide opening 352. The retaining rib 353 extends along the width of the drying duct 30, that is, along the length of the mounting slot 34. For example, the retaining rib 353 is disposed at one end of the expansion duct 35 near the filter device 50. In this case, the air guide opening 352 is formed between the retaining rib 353 and the top wall 5217.

[0145] The top of the sidewall 5214 of the second slot 5212 abuts against the bottom of the retaining rib 353, allowing the retaining rib 353 to limit the position of the filter device. The retaining rib 353 extends to the top of the second slot 5212, ensuring that the bottom of the air guide port 352 is higher than the top of the second slot 5212. Therefore, the provision of the retaining rib 353 ensures that the filter device 50 is securely fixed and that the air guide port 352 is always located above the second slot 5212.

[0146] 11 to 15 , the laundry processing apparatus 100 further includes a soap box 60, which is disposed on top of the drum assembly 20 and communicates with the laundry receiving chamber 21. Furthermore, the soap box 60 is connected to an external water source, allowing external water to enter the soap box 60 and further into the laundry receiving chamber 21. In some applications, the laundry processing apparatus is a washer-dryer. In this case, the soap box 60 can provide washing water to the laundry receiving chamber 21. The soap box 60 can also contain detergent, which can enter the laundry receiving chamber 21 through the external water source to wash the laundry.

[0147] In some embodiments, the soap box 60 is located on one side of the drying duct 30, and the filter device 50 is disposed between the soap box 60 and the heat pump system 40, that is, the filter frame 521 is disposed between the soap box 60 and the heat pump system 40. For example, the soap box 60 is located on one side (e.g., the left side) of the air expansion duct 35 and is disposed adjacent to the air expansion duct 35.

[0148] In some embodiments, because the second air inlet 301 is located behind the soap box 60, the air expansion duct 35 is partially located at the top of the soap box 60. This increases the space for the air expansion duct 35 and allows the air guide structure 39 to be positioned at an angle. For example, the end of the air guide structure 39 closest to the second air inlet 301 is located at the top of the center of the soap box 60. The end of the air guide structure 39 facing away from the second air inlet 301 is tilted toward the heat pump system 40 until it is located at the top right edge of the soap box 60.

[0149] In some embodiments, the case 10 further includes a panel 14, which is located on the side of the case 10 closest to the user. For example, referring to FIG. 1A , the panel 14 is located at the upper front portion of the case 10. The panel 14 defines an assembly opening 15. For example, the assembly opening 15 is located on the left side of the panel 14. The soap box 60 includes a main body and a pull-out portion, with the pull-out portion of the soap box 60 corresponding to the assembly opening 15. This allows the soap box 60 to be pulled out through the assembly opening 15 when detergent is needed, and then assembled into the case 10 through the assembly opening 15 after detergent addition is complete.

[0150] 1A and 2 , the laundry processing device 100 further includes a control panel 70. For example, the control panel 70 is disposed on the panel 14 of the housing 10. A user can input control commands through the control panel 70 to control the laundry processing device 100. In this case, the filter device 50 can be located between the control panel 70 and the soap dish 60. For example, one side (e.g., the right side) of the end portion of the mounting portion 51 of the filter device 50 is disposed adjacent to the control panel 70, while the other side (e.g., the left side) of the end portion of the mounting portion 51 of the filter device 50 is disposed adjacent to the pull-out portion at the front of the soap dish 60.

[0151] Therefore, through the above arrangement, the filter device 50 reasonably utilizes the space at the top of the box 10. The installation portion 51 of the filter device 50 is arranged between the control panel 70 and the pull-out portion of the soap box 60, which can reasonably utilize the space at the front of the box 10.

[0152] Referring to Figures 28 to 30 , the laundry processing apparatus 100 further includes an exhaust duct 90 disposed on the top of the soap box 60. One end of the exhaust duct 90 communicates with the interior of the soap box 60, and the other end communicates with the air expansion duct 35. The exhaust duct 90 can be integrated into the top wall of the soap box 60, thereby constituting a portion of the exhaust duct 90. Alternatively, the exhaust duct 90 can be formed separately from the top wall of the soap box 60, which is not limited in this disclosure. In some embodiments of the present disclosure, the top wall of the soap box 60 constitutes a portion of the exhaust duct 90.

[0153] By providing the exhaust duct 90 , the air in the soap box 60 can pass through the exhaust duct 90 into the air expansion duct 35 , then into the clothing receiving cavity 21 , and finally be discharged from the housing 10 , thereby achieving exhaust inside the soap box 60 .

[0154] It will be appreciated that the majority of the air flowing from the exhaust duct 90 into the expansion duct 35 flows in the same direction as the air within the expansion duct 35, resulting in the majority of the air exiting the exhaust duct 90 entering the clothing receiving chamber 21 through the first air inlet 212. With this arrangement, when the clothing processing apparatus 100 dries clothing, the air flowing out of the exhaust duct 90 merges with the air flowing into the expansion duct 35 to enter the first chamber 36 and ultimately the clothing receiving chamber 21, thereby enhancing the air flow within the drying duct 30. Furthermore, the air exhausted from the exhaust duct 90 is humid air. After being processed by the heat pump system 40 within the first chamber 36, the air entering the clothing receiving chamber 21 is relatively dry, thus preventing any impact on clothing drying. Of course, in some embodiments, some of the air exiting the exhaust duct 90 may flow in a direction opposite to the flow of the air within the expansion duct 35, entering the clothing receiving chamber 21 through the first air outlet 211.

[0155] It is understood that in order to exhaust excess air from the soap box 60, some clothing processing devices are provided with an air duct connecting the inner cavity of the soap box 60 with the clothing receiving cavity 21. This makes the clothing processing device structure complex and inconvenient to install. In some embodiments of the present disclosure, the exhaust duct 90 is provided to exhaust excess air from the soap box 60 into the air expansion duct 35 and ultimately into the clothing receiving cavity 21, thereby omitting the provision of an air duct and simplifying the structure of the clothing processing device 100.

[0156] 29 and 30 , the laundry processing apparatus 100 further includes an air baffle 91 disposed within the exhaust duct 90. For example, the air baffle 91 is disposed on a sidewall of the exhaust duct 90. The air baffle 91 is configured to reduce air backflow from the drying duct 30 into the exhaust duct 90. One side of the air baffle 91 is secured to the sidewall of the exhaust duct 90, while the other side of the air baffle 91 extends into the exhaust duct 90. The air baffle 91 is arranged to protrude from the inner wall of the exhaust duct 90 but does not completely separate the exhaust duct 90. This prevents backflowing air, while allowing air in the soap box 60 to pass through the air baffle 91 and enter the expansion duct 35.

[0157] To ensure that the air baffle 91 effectively prevents air backflow, it is curved, with the inner side of the arc facing toward the drying duct 30, specifically, toward the expansion duct 35. When backflowing air strikes the curved inner side of the air baffle 91, it guides the air toward the expansion duct 35, thereby further reducing backflow. Furthermore, as air from the soap box 60 enters the expansion duct 35, it strikes the outer side of the arc of the air baffle 91, which guides the air toward the expansion duct 35, ensuring that sufficient air from the soap box 60 enters the expansion duct 35.

[0158] 29 and 30 , there may be a plurality of air baffles 91 , which are arranged in sequence along the air flow direction of the exhaust duct 90 and cross-arranged on two opposite side walls of the exhaust duct 90 to separate the exhaust duct 90 into a curved extending duct.

[0159] For example, the two opposing side walls of the exhaust duct 90 are a first side wall and a second side wall, and the number of the air baffles 91 is four, namely a first air baffle, a second air baffle, a third air baffle, and a fourth air baffle. In this case, the first air baffle, the second air baffle, the third air baffle, and the fourth air baffle are sequentially spaced apart along the air flow direction of the exhaust duct 90, with the first air baffle being disposed on the first side wall, the second air baffle being disposed on the second side wall, the third air baffle being disposed on the first side wall, and the fourth air baffle being disposed on the second side wall.

[0160] Of course, the drawings of the present disclosure only show two wind-blocking plates 91. The number of wind-blocking plates 91 can be set according to the desired effect, and the present disclosure does not impose any restrictions on this.

[0161] It can be understood that after the exhaust air duct 90 is divided into an air duct extending in a curved shape by the air blocking piece 91, the effect of preventing air backflow can be further improved.

[0162] To further ensure that the air baffles 91 divide the exhaust duct 90 into curved ducts, the height of the air baffles 91 can be consistent with the height of the exhaust duct 90. In this case, the air flowing back into the exhaust duct 90 can only flow forward from the side of the air baffle 91 to the next air baffle 91, and will not pass through the air baffle 91 through the gap at the top and flow into the soap box 60.

[0163] Referring to Figure 30 , the exhaust duct 90 includes a first section 92, which is located at one end of the exhaust duct 90 near the drying duct 30 and is encircled by a dotted line. The first section 92 primarily prevents air backflow, and the air blocking plate 91 is disposed on the sidewall of the first section 92 and within the first section 92.

[0164] For example, the width of the first section 92 gradually decreases as air flows from the soap box 60 into the drying duct 30. That is, the width of the first section 92 at the end away from the expansion duct 35 is greater than the width at the end closer to the expansion duct 35. By configuring the first section 92 in this shape, the opening where the first section 92 connects to the expansion duct 35 is smaller, further reducing air backflow. Furthermore, the width of the first section 92 gradually increases as it moves away from the opening, ensuring that the air in the soap box 60 is effectively guided into the expansion duct 35.

[0165] The exhaust duct 90 also includes a second section 93, which is located on the side of the first section 92 away from the expansion duct 35. One end of the second section 93 is connected to the first section 92, and the other end of the second section 93 is connected to the interior of the soap box 60. The exhaust duct 90 is now divided into the first section 92 and the second section 93. The second section 93 is bent relative to the first section 92, forming a predetermined angle with the first section 92. Air returning from the expansion duct 35 is blocked by the inner wall of the bent exhaust duct 90, thereby reducing air backflow.

[0166] For example, the laundry processing apparatus 100 further includes a partition 96, which separates the first section 92 from the second section 93. The first section 92 and the second section 93 are located on either side of the partition 96. The first section 92 and the second section 93 are closely arranged, further reducing air backflow.

[0167] In some embodiments, the first cover plate 31 is not only disposed on the top of the drying duct 30, but also covers the top wall of the soap box 60, thereby forming the exhaust duct 90 together with the top wall of the soap box 60. It will be understood that in this embodiment, the first cover plate 31 constitutes the top wall of the drying duct 30 and the top wall of the exhaust duct 90.

[0168] 31 and 32 , in some embodiments, the top wall of the soap box 60 is part of the support plate 80. The support plate 80 constitutes the top wall of the soap box 60 and the bottom wall of the drying duct 30. The exhaust duct 90 is disposed between the support plate 80 and the first cover plate 31.

[0169] It is understood that in some laundry processing devices, the soap box body has an open opening, which is arranged at the top of the soap box body. The soap box cover is covered with the open opening to form the top wall of the soap box 60. The soap box cover and the soap box body define a receiving cavity for receiving detergent.

[0170] Because the soap box cover occupies the top space of the cartridge assembly 20, the space available for accommodating the duct member 3 is reduced, thereby reducing the space for the air expansion duct 35. Therefore, in some embodiments of the present disclosure, the soap box cover is eliminated, and a support plate 80 is extended and arranged on the top of the soap box body. The support plate 80 covers the open opening of the soap box body to form the top wall of the soap box 60. The support plate 80 and the soap box body define the accommodating cavity. This increases the installation space for the duct member 3, thereby increasing the space for the air expansion duct 35.

[0171] The top wall of the soap box 60 and the bottom wall of the drying duct 30 are integrally formed through the support plate 80, thereby simplifying the structure of the clothing processing device 100 for easy installation, and improving the sealing of the drying duct 30. In addition, the arrangement between the soap box 60 and the duct member 3 is made compact to improve the utilization rate of the top space of the drum assembly 20.

[0172] In some embodiments, the support plate 80 is snap-connected to the soap box body. A snap is provided on the edge of one of the support plate 80 and the soap box body, and a snap-fit ​​structure is provided at a corresponding position on the other to facilitate installation and removal of the soap box 60 from the housing 10. When the soap box 60 is installed in the housing 10, the snap engages with the snap-fit ​​structure to secure the support plate 80 and the soap box body. A water diversion plate may also be provided on the top of the soap box 60 to direct wash water into the soap box 60. The water diversion plate may be fixedly connected to the bottom surface of the support plate 80.

[0173] In some embodiments, the laundry processing apparatus 100 further includes a recess 94. For example, the top wall of the soap box 60 is recessed downward to form the recess 94. The recess 94 communicates with the interior of the soap box 60, and the first cover 31 is disposed over the recess 94 to enclose and form the exhaust duct 90. The first cover 31 engages with the opening at the top of the recess 94, thereby sealing the upper opening of the recess 94 to form the exhaust duct 90. The interior of the recess 94 now constitutes the interior of the exhaust duct 90.

[0174] The laundry processing apparatus 100 further includes an exhaust hole 95 formed in the bottom wall of the recess 94. The exhaust hole 95 connects the inner cavity of the soap box 60 and the recess 94. Air inside the soap box 60 can flow through the exhaust hole 95 into the recess 94 and then into the exhaust duct 90. For example, the exhaust hole 95 is disposed at an end of the recess 94 away from the air diffusion duct 35, so that air discharged from the exhaust hole 95 flows along the direction of air flow in the exhaust duct 90 and enters the air diffusion duct 35.

[0175] Of course, in other embodiments, the first cover plate 31 may be raised upward to form a groove 94, which, together with the top wall of the soap box 60, forms the exhaust duct 90. Alternatively, both the top wall of the soap box 60 and the first cover plate 31 may have grooves, and the shapes and sizes of the grooves formed by the two grooves match, so that when the first cover plate 31 is placed on the top wall of the soap box 60, the grooves of the two grooves form the exhaust duct 90. Of course, the configuration of the exhaust duct 90 is not limited to the above-described embodiment, and the present disclosure is not limited thereto.

[0176] In some embodiments, the connection between the exhaust duct 90 and the expansion duct 35 is located at the end of the expansion duct 35 near the first air outlet 211. This allows the air exiting the expansion duct 35 near the first air outlet 211 to have a higher velocity, allowing the air at the connection to be smoothly discharged. The connection is oriented in the direction of air flow in the expansion duct 35, allowing the air discharged from the connection to more easily pass through the expansion duct 35 and enter the first chamber 36.

[0177] One end of the expansion duct 35, near the first air outlet 211, is connected to the first air duct 32, which is disposed at the rear of the duct member 3. Therefore, the exhaust duct 90 is located at the rear of the support plate 80, and is located behind the soap box 60 and on one side (e.g., the left side) of the first air duct 32.

[0178] 31 and 32 , the first cover plate 31 includes a first covering portion 311 and a second covering portion 312. The first covering portion 311 constitutes the main portion of the first cover plate 31, and the second covering portion 312 is located on one side (such as the left side) of the first covering portion 311. The first covering portion 311 constitutes at least a portion of the top wall of the drying air duct 30, and the second covering portion 312 constitutes at least a portion of the top wall of the exhaust air duct 90. At this time, the support plate 80 also has an exhaust area 81, and the groove 94 is provided at the exhaust area 81. The shape and size of the exhaust area 81 match the shape and size of the second covering portion 312, so that the second covering portion 312 covers the groove 94 to form the exhaust air duct 90.

[0179] In the case where the filter device 50 includes the mounting portion 51 and the filter portion 52 , and the mounting portion 51 is disposed at the first opening 341 , the structure of the mounting portion 51 will be described below.

[0180] 33 to 35 , the mounting portion 51 has a second cavity 511. The mounting portion 51 further includes a rotating member 512, a first elastic member 513, and a pressing member 514. The second cavity 511 is configured to accommodate the rotating member 512, the first elastic member 513, and the pressing member 514 to secure the mounting portion 51 to the first opening 341 of the mounting slot 34.

[0181] Referring to Figures 36 to 38 , the rotating member 512 is partially disposed within the second cavity 511 and is capable of rotating about its own rotational axis. For example, the rotational axis can be an axis of the rotating member 512 itself. The rotating member 512 also includes a stopper 5121 disposed on one side of the rotating member 512. The stopper 5121 extends through the sidewall of the mounting portion 51 to be at least partially exposed in the second cavity 511.

[0182] In some embodiments, the mounting portion 51 and the filter portion 52 are integrally formed. In this case, the mounting portion 51 further comprises a chute 515 formed in a sidewall of the mounting portion 51. The chute 515 extends along the length of the filter device 50, and the stopper 5121 passes through the chute 515 and is at least partially exposed in the second cavity 511.

[0183] One end of the first elastic member 513 is connected to the rotating member 512, and the other end is connected to the second cavity 511. For example, the other end of the first elastic member 513 is fixed to the inner wall of the second cavity 511. The first elastic member 513 is capable of elastic deformation, thereby expanding and contracting along its own length. The first elastic member 513 can be a spring as shown in Figure 37, or an elastic structure such as an elastic sheet or elastic rod, which is not limited in this disclosure.

[0184] One end of the pressing member 514 is connected to the rotating member 512, and the other end is exposed in the second cavity 511 and located on the end surface of the mounting portion 51. At this time, the pressing member 514 is located on the side of the rotating member 512 near the end of the mounting portion 51, so that the user can press the pressing member 514 provided on the end surface of the mounting portion 51.

[0185] It should be noted that, based on the positional relationship between the first elastic member 513 and the rotating member 512, the first elastic member 513 can also be disposed on the same side of the rotating member 512 as the pressing member 514. The accompanying drawings show that the first elastic members 513 are disposed on opposite sides of the pressing member 514, but this is not limited thereto.

[0186] 39 to 41 , a limiting groove 342 is provided on the side wall of the first opening 341 . For example, the limiting groove 342 extends along the length direction of the mounting groove 34 , and an open end of the limiting groove 342 is located at the end of the mounting groove 34 .

[0187] In combination with the above, during the assembly of the filter device 50, the mounting portion 51 will move toward the inside of the first opening 341. When the limiting portion 5121 is engaged with the limiting groove 342, the rotating member 512 will rotate around its own rotation axis.

[0188] During the rotation of the rotating member 512, the rotating member 512 compresses the first elastic member 513. When the mounting portion 51 is finally assembled into the first opening 341, the first elastic member 513 is still in a compressed state to press against the rotating member 512, thereby causing the limiting portion 5121 of the rotating member 512 to be securely engaged in the limiting groove 342 due to the elastic force of the first elastic member 513.

[0189] When the pressing member 514 is pressed, the pressing member 514 exerts a force on the rotating member 512 to rotate the rotating member 512 . When the rotating member 512 rotates, the first elastic member 513 is further compressed. At this time, the limiting portion 5121 is disengaged from the limiting groove 342 .

[0190] It is understood that when the limiting portion 5121 is engaged with the limiting slot 342, the rotating member 512 rotates in the first direction. During this rotation, the limiting portion 5121 always abuts against the top wall of the limiting slot 342 and moves toward the bottom wall of the limiting slot 342. When the pressing member 514 is pressed, the rotating member 512 continues to rotate in the first direction, and the limiting portion 5121 continues to move toward the bottom wall of the limiting slot 342, thereby disengaging the limiting portion 5121 from the top wall of the limiting slot 342, thereby allowing the mounting portion 51 to be easily removed from the mounting slot 34.

[0191] 40 , in some embodiments, the limiting groove 342 includes a sliding groove 3421 and a snap-fit ​​groove 3422 . The sliding groove 3421 extends along the length direction of the mounting groove 34 , and the snap-fit ​​groove 3422 is disposed on the upper or lower wall of the sliding groove 3421 and is connected to the sliding groove 3421 .

[0192] Taking the engagement groove 3422 provided on the upper wall of the sliding groove 3421 as an example, the engagement process and the disengagement process of the limiting portion 5121 are described as follows:

[0193] As the limiting portion 5121 engages with the engaging groove 3422, the limiting portion 5121 always abuts against the top wall of the limiting groove 342, that is, against the top wall of the sliding groove 3421. As the mounting portion 51 moves toward the interior of the first opening 341, the limiting portion 5121 slides on the top wall and eventually slides into the engaging groove 3422. After the limiting portion 5121 slides into the engaging groove 3422, the first elastic member 513 remains in a compressed state, pressing against the rotating member 512, causing the limiting portion 5121 to press against the engaging groove 3422, ensuring that the mounting portion 51 is firmly fixed in the mounting groove 34. When the pressing member 514 is pressed, the pressing member 514 rotates, causing the limiting portion 5121 to move downward, thereby disengaging the limiting portion 5121 from the engaging groove 3422, allowing the filter device 50 to be removed.

[0194] Of course, when the locking groove 3422 is set on the lower wall of the sliding groove 3421, the process of the limiting portion 5121 locking in and disengaging from the locking groove 3422 is similar to the above process. At this time, the limiting portion 5121 will be against the bottom wall of the sliding groove 3421.

[0195] In some embodiments, an upper wall or a lower wall of the engaging groove 3422 is provided with an inclined surface 3423, and the inclined surface 3423 is provided near the opening of the engaging groove 3422. During assembly of the filter device 50, the mounting portion 51 moves toward the interior of the first opening 341, and the stopper 5121 slides on the inclined surface 3423 and then slides from the inclined surface 3423 into the engaging groove 3422, thereby facilitating the engagement of the stopper 5121.

[0196] For example, when the engaging groove 3422 is provided on the top wall of the sliding groove 3421, the inclined surface 3423 extends downward, and the top of the inclined surface 3423 is closer to the outside of the first opening 341 than the bottom of the inclined surface 3423. When the engaging groove 3422 is provided on the bottom wall of the sliding groove 3421, the inclined surface 3423 extends downward, and the top of the inclined surface 3423 is closer to the outside of the first opening 341 than the bottom of the inclined surface 3423. It is understood that the depth of the first opening 341 is relative to the length of the filter device 50, so that the interior of the first opening 341 is closer to the interior of the drying air duct 30, and the exterior of the first opening 341 is closer to the exterior of the drying air duct 30.

[0197] Referring to Figures 41 to 43 , the rotating member 512 further includes a first connecting portion 5122 and a second connecting portion 5123. The first connecting portion 5122 and the second connecting portion 5123 are connected and arranged at an angle. The rotation axis of the rotating member 512 is located at the junction of the first connecting portion 5122 and the second connecting portion 5123. The limiting portion 5121 is provided on one side (e.g., the right side) of the first connecting portion 5122, and the second connecting portion 5123 is connected to the first elastic member 513.

[0198] In some embodiments, the first connecting portion 5122 and the second connecting portion 5123 are both structures extending along a straight line. The first connecting portion 5122 and the second connecting portion 5123 are integrally formed to ensure the stability of the rotating member 512 structure. The angle between the first connecting portion 5122 and the second connecting portion 5123 is the angle formed between the length direction of the first connecting portion 5122 and the length direction of the second connecting portion 5123. The size of this angle can be set according to actual needs. For example, the angle between the first connecting portion 5122 and the second connecting portion 5123 can be 90°.

[0199] The rotation axis of the rotating member 512 can be perpendicular to the length direction of the first connecting portion 5122 and the second connecting portion 5123. When the rotating member 512 is disposed in the second cavity 511, the rotation axis can be disposed horizontally and perpendicular to the length direction of the filter device 50. Of course, the arrangement of the rotation axis is not limited to this, and the present disclosure does not impose any restrictions on this.

[0200] 42 and 43 , the rotating member 512 further includes a rotating shaft 5124, which is disposed at the junction of the first connecting portion 5122 and the second connecting portion 5123. The central axis of the rotating shaft 5124 serves as the rotation axis of the rotating member 512. The first connecting portion 5122 and the second connecting portion 5123 are rotatably disposed on the rotating shaft 5124. The rotating shaft 5124 can be fixed to the inner wall of the second cavity 511, thereby allowing the first connecting portion 5122 and the second connecting portion 5123 to rotate about the rotating shaft 5124. The first connecting portion 5122 and the second connecting portion 5123 can also be fixed to the rotating shaft 5124. In this case, the rotating shaft 5124 is rotatably disposed on the inner wall of the second cavity 511, thereby allowing the first connecting portion 5122 and the second connecting portion 5123 to rotate through rotation of the rotating shaft 5124.

[0201] 42 , the first elastic member 513 and the pressing member 514 are respectively located on opposite sides of the second connection portion 5123, and the first elastic member 513 and the first connection portion 5122 are located on the same side of the second connection portion 5123. At this time, the first elastic member 513 and the first connection portion 5122 are located on a side of the second connection portion 5123 away from the pressing member 514.

[0202] 44 and 45 , the mounting portion 51 further includes a second elastic member 516 and a sliding member 517. The second elastic member 516 is disposed within the second cavity 511 and is fixed at one end. The sliding member 517 is connected to the other end of the second elastic member 516. The sliding member 517 partially passes through the bottom wall of the mounting portion 51 to protrude relative to the bottom wall. The sliding member 517 can slide to counteract the elastic force of the second elastic member 516.

[0203] For example, the second elastic member 516 and the first elastic member 513 can be similar elastic members, such as springs, but with different spring stiffnesses. The sliding member 517 can be fixed to the other end of the second elastic member 516, so that the second elastic member 516 can drive the sliding member 517 to slide, and the sliding member 517 can also slide to resist the elastic force of the second elastic member 516. It is understood that the sliding member 517 can slide on the bottom wall of the second cavity 511.

[0204] 40 , the mounting groove 34 further includes a protrusion 343 . The protrusion 343 is arranged to protrude relative to the bottom wall of the first opening 341 , and a certain distance is provided between the protrusion 343 and the end of the first opening 341 .

[0205] In light of the above, when the mounting portion 51 moves toward the interior of the first opening 341 for assembly, the sliding member 517 abuts against the protrusion 343. As the mounting portion 51 continues to move toward the interior of the first opening 341, the sliding member 517 moves relative to the end of the mounting portion 51 within the second cavity 511, thereby causing the sliding member 517 to compress the second elastic member 516. When the limiting portion 5121 engages with the limiting groove 342, the second elastic member 516 reaches its maximum compression. The elastic force generated by the compression of the second elastic member 516 causes the mounting portion 51 to move toward the exterior of the first opening 341.

[0206] When the pressing member 514 is pressed to cause the limiting portion 5121 to disengage from the limiting groove 342, the elastic force of the second elastic member 516 causes the mounting portion 51 to move toward the outside of the first opening 341, thereby causing the filter device 50 to move toward the outside of the first opening 341. At this time, the filter device 50 will pop out under the elastic force of the second elastic member 516, making it easier for the user to take it.

[0207] 45 , the sliding member 517 includes a first sliding portion 5171 and a second sliding portion 5172 fixed to each other. The upper sliding portion 5171 is located within the second cavity 511 and is fixed to the second elastic member 516. The bottom wall of the mounting portion 51 is provided with a slide groove 515 extending along the length of the mounting portion 51. The second sliding portion 5172 passes through the slide groove 515 to be partially exposed in the second cavity 511, and the second sliding portion 5172 is able to slide in the slide groove 515.

[0208] For example, the first sliding portion 5171 and the second sliding portion 5172 are integrally formed to ensure the structural stability of the sliding member 517. The first sliding portion 5171 can move within the second cavity 511, thereby causing the first sliding portion 5171 to drive the second sliding portion 5172 to move. The upper portion of the second sliding portion 5172 adjacent to the first sliding portion 5171 is smaller in size, allowing the upper portion of the second sliding portion 5172 to be positioned within the chute 515. The lower portion of the second sliding portion 5172 is larger in size, ensuring that the lower portion of the second sliding portion 5172 is positioned outside the second cavity 511.

[0209] 45 , the first sliding portion 5171 has a first groove 51711. The opening of the first groove 51711 faces the second elastic member 516. The second elastic member 516 is partially disposed in the first groove 51711. One end of the second elastic member 516 is fixed to the bottom of the first groove 51711, so that the sliding member 517 can slide under the pressure of the second elastic member 516.

[0210] For example, the first sliding portion 5171 is hollow to form a first groove 51711. The opening of the first groove 51711 is located at an end of the first sliding portion 5171 near the second elastic member 516, thereby allowing the second elastic member 516 to be partially accommodated in the first groove 51711. When the second elastic member 516 undergoes elastic deformation, the first groove 51711 acts as a limiter for the second elastic member 516, allowing the second elastic member 516 to undergo elastic deformation only in the longitudinal direction of the second elastic member 516. In this case, the shape of the first groove 51711 matches the shape of the second elastic member 516.

[0211] Referring to Figure 45 , in some embodiments, the mounting portion 51 further includes a housing 518 disposed within the second cavity 511. The second elastic member 516 and the first sliding portion 5171 are both disposed within the housing 518. For example, the housing 518 is secured within the second cavity 511 such that the housing 518 cannot move relative to the inner wall of the second cavity 511. In this case, one end of the second elastic member 516 is secured to the inner wall of the housing 518, thereby securing the housing relative to the inner wall of the second cavity 511.

[0212] By providing the accommodating box 518, the second elastic member 516 and the sliding member 517 are both fixed to the accommodating box 518. The accommodating box 518 can be removed to remove the second elastic member 516 and the sliding member 517, thereby meeting the maintenance requirements of specific scenarios. In this case, the accommodating box 518 has an opening on one side, through which the second elastic member 516 and the sliding member 517 can be placed into the accommodating box 518, also facilitating their removal. A snap-fitting portion 5181 is provided on the side of the accommodating box 518 with the opening. The snap-fitting portion 5181 is configured to engage with other structures of the mounting portion 51 (such as the first mounting shell 5191), thereby achieving installation of the accommodating box 518.

[0213] 46 and 47 , the bottom wall of the accommodating box 518 constitutes a portion of the bottom wall of the mounting portion 51, and the side walls of the accommodating box 518 constitute a portion of the side walls of the mounting portion 51. A slide groove 515 is formed between the accommodating box 518 and other portions of the mounting portion 51 (such as the rotating member 512), thereby enabling the second sliding portion 5172 to slide within the slide groove 515. It will be appreciated that by constituting the bottom wall and side walls of the accommodating box 518 as the bottom wall and side walls of the mounting portion 51, the accommodating box 518 can be easily removed from the mounting portion 51.

[0214] 37 , in some embodiments, the mounting portion 51 includes a first mounting shell 5191 and a second mounting shell 5192 disposed along the length of the mounting portion 51. The first mounting shell 5191 and the second mounting shell 5192 are both hollow to form a second cavity 511. The first mounting shell 5191 and the second mounting shell 5192 can be connected by snapping, thereby facilitating connection and removal.

[0215] For example, the first mounting shell 5191 is connected to the filter unit 52, the rotating member 512 and the first elastic member 513 are both disposed in the first mounting shell 5191, and the pressing member 514 is disposed in the second mounting shell 5192. In this case, the first elastic member 513 and the rotating member 512 can be installed before being assembled into the first mounting shell 5191. In conjunction with the above, the chute 515 is provided on the side wall of the first mounting shell 5191, and the sliding member 517 and the receiving box 518 are also disposed in the first mounting shell 5191.

[0216] The mounting portion 51 further includes a second cover plate 5193, which is disposed on an end of the second mounting shell 5192 away from the first mounting shell 5191. The second cover plate 5193 covers the opening at the end of the second mounting shell 5192 and is provided with a through hole, allowing one end of the pressing member 514 to pass through the through hole and partially expose the surface of the cover plate 5193. At this time, the user can eject the filter device 50 by pressing the portion of the pressing member 514 exposed on the second cover plate 5193.

[0217] 37 , in some embodiments, the second mounting shell 5192 is provided with a limiting structure 5194. The limiting structure 5194 is fixed to the inner wall of the second mounting shell 5192. A through hole is provided in the middle of the limiting structure 5194, through which the pressing member 514 passes and can slide. In this case, the limiting structure 5194 primarily supports and limits the position of the pressing member 514, so that after being pressed by a user, the pressing member 514 can slide within the limiting structure 5194 and maintain a stable position.

[0218] Referring to Figure 48 , the duct member 3 also includes a connector 38. The connector 38 is disposed at an edge of the duct member 3. For example, the connector 38 is disposed at the location of the second air inlet 301. The connector 38 communicates with the first air outlet 211 via the first air duct 32. For example, one end of the first air duct 32 communicates with the connector 38, and the other end of the first air duct 32 communicates with the first air outlet 211, allowing air flowing out of the first air outlet 211 to flow along the first air duct 32 toward the connector 38.
