[0085] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0086] It should be noted that when a component is referred to as being "fixed to" or "disposed on" another component, it may be fixed or disposed on the other component directly or indirectly. When a component is referred to as being "connected to" another component, it may be directly or indirectly connected to the other component.

[0087] In order to illustrate the technical solution described in this application, the following is a detailed description with reference to specific drawings and embodiments.

[0088] See also Figures 1 to 4 As shown, an embodiment of the present application provides a clothing processing device 200.

[0089] For the purpose of description and understanding, the directions of "up", "down", "left", "right", "front" and "back" are defined herein based on the normal working state of the laundry treating apparatus 200. The side of the laundry treating apparatus 200 facing the user is "front", the side facing away from the user is "back", the side facing the ground is "down", the side facing away from the ground is "up", the side corresponding to the left hand of the user is "left", and the side corresponding to the right hand of the user is "right".

[0090] As shown in Figures 1 to 4 , the laundry treating apparatus 200 comprises an apparatus housing 1, and a drying module 100, a first driving member 5 and a drum 2 arranged in the apparatus housing 1. The first driving member 5 is connected with the drum 2 and used to drive the drum 2 to rotate.

[0091] As shown in Figure 2 , Figure 3 and Figure 4 , the apparatus housing 1 can comprise a plurality of outer standing plates 15 connected with each other to enclose the drying module 100. For example, the plurality of outer standing plates 15 of the apparatus housing 1 can comprise an upper side plate (or referred to as an upper cover plate), a front side plate (or referred to as a door plate), a left side plate, a right side plate and a back side plate, etc. In other embodiments, the plurality of outer standing plates 15 can be connected in other numbers and orientations.

[0092] Please refer to Figure 2 , Figure 3 and Figure 4 , and Figure 8 , the drum 2 is provided with an air inlet 21 and an air outlet 23, and the space between the air inlet 21 and the air outlet 23 serves as a laundry treating space 22.

[0093] Referring to Figure 2 and Figure 3 , the apparatus housing 1 can further comprise a first support member 16 and a second support member (not shown). The first support member 16 is arranged between the front side plate and the drum 2, and the second support member (not shown) is arranged between the back side plate and the drum 2. The drum 2 is rotatably mounted at both axial ends thereof between the first support member 16 and the second support member. In some embodiments, the second support member can be integrally arranged with the back side plate.

[0094] In one embodiment, the air inlet 21 of the drum 2 can be arranged towards the front, i.e. towards the first support member 16.

[0095] As shown in Figure 5 and Figure 6 , the drying module 100 can comprise a base assembly 11. The base assembly 11 is located below the drum 2, and the plurality of outer standing plates 15 are connected with the periphery of the base assembly 11 to enclose the drum 2.

[0096] Referring to Figure 5 , Figure 6 and Figure 7 As shown, in one embodiment, in the laundry processing device 200, the drying module 100 may further include a heat pump system 3 and a moisture absorption and dehumidification system 4. The heat pump system 3 is used to provide at least one cold source and at least one heat source to perform primary condensation dehumidification and heating on the air flowing out of the drum 2. The moisture absorption and dehumidification system 4 is used to perform primary moisture absorption and dehumidification (secondary dehumidification) on the air flowing out of the drum 2.

[0097] See also Figure 6 As shown, the heat pump system 3 includes: a compressor 31, a second heat exchanger 34, a throttling device 36 and a first heat exchanger 32 connected in sequence along the refrigerant flow direction.

[0098] The refrigerants include hydrofluorocarbons (HFCs), chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), or natural refrigerants (such as ammonia, carbon dioxide, hydrocarbons, etc.). The second heat exchanger 34 acts as a heat source to heat the air, allowing the high-temperature air to enter the drum 2. The first heat exchanger 32 acts as a cold source to cool and condense the air flowing out of the drum 2.

[0099] In one embodiment, if Figure 6 and Figure 7 As shown, the base assembly 11 defines a main drying air duct 110, and the base assembly 11 further defines a receiving cavity 112 isolated from the main drying air duct 110. The air inlet end of the main drying air duct 110 is connected to the air outlet 23 of the drum 2, and the air outlet end of the main drying air duct 110 is connected to the air inlet 21 of the drum 2. Figure 6 and Figure 7 As shown, in the heat pump system 3 , the first heat exchanger 32 and the second heat exchanger 34 are arranged in the main drying air duct 110 along the wind direction, and the compressor 31 and the throttling device 36 are arranged in the accommodating cavity 112 of the base assembly 11 .

[0100] Also, see Figure 5 As shown, components not involved in air circulation, such as the first driving member 5 , are also arranged in the accommodating cavity 112 .

[0101] After the air passes through the first heat exchanger 32, the temperature and absolute humidity of the air decrease, while the relative humidity increases. After the air passes through the second heat exchanger 34, the temperature of the air increases, while the relative humidity decreases.

[0102] In one embodiment, the first heat exchanger 32 comprises a first evaporator and the second heat exchanger 34 comprises a condenser.

[0103] Absolute humidity: refers to the mass of water vapor contained in unit volume of air, which directly reflects the actual content of water vapor in the air.

[0104] Relative humidity: refers to the percentage of the actual water vapor content in the air (absolute humidity) to the saturated water vapor content at the same temperature. It is a relative concept used to describe the degree to which the water vapor content in the air is close to saturation.

[0105] When the absolute humidity remains constant, a drop in temperature will cause the relative humidity to rise, and may even reach a state of water vapor saturation, resulting in condensation. When the absolute humidity remains constant, a rise in temperature will cause the relative humidity to fall, and the degree of water vapor unsaturation in the air will increase.

[0106] Therefore, after passing through the second heat exchanger 34, the air becomes high temperature and low humidity (low absolute humidity, low relative humidity), and after re-entering the drum 2, it can effectively take away moisture from the clothes.

[0107] The moisture absorption and dehumidification system 4 is used to absorb and dehumidify the air flowing out of the drum 2 (secondary dehumidification). At least a portion of the moisture absorption and dehumidification system 4 is disposed within the main drying air duct 110, between the first heat exchanger 32 and the second heat exchanger 34. The system is used to absorb and dehumidify the low-temperature air after the first heat exchanger 32, thereby further reducing the absolute humidity and relative humidity of the air.

[0108] Please refer to Figure 16 As shown, in some embodiments, the moisture absorption and dehumidification system 4 includes at least a moisture absorption and dehumidification component 42, a moisture absorption and dehumidification shell 41 and a regeneration component 44. The moisture absorption and dehumidification component 42 is arranged in the moisture absorption and dehumidification shell 41 to perform the moisture absorption and dehumidification function.

[0109] Please refer to Figure 22 As shown, the space inside the moisture absorption and dehumidification housing 41 is divided into a moisture absorption area 4102 and a desorption area 4101. Figure 16 As shown, the moisture absorption and desorption member 42 includes a moisture absorption portion 4201 located in the moisture absorption zone 4102 and a desorption portion 4202 located in the desorption zone 4101. The regeneration assembly 44 is in communication with the desorption zone 4101 and is used to provide high-temperature air into the desorption zone 4101, thereby providing energy (heat) for desorption of moisture in the desorption portion 4202.

[0110] In some embodiments, the shape of the moisture absorption and desorption housing 41 can be designed based on actual operating requirements, as long as it includes at least two functional areas: a moisture absorption area 4102 and a desorption area 4101. The shape of each functional area can also be designed based on actual needs and can be square, triangular, circular, or even fan-shaped, as long as the moisture absorption area 4102 and the desorption area 4101 are isolated from each other. In some embodiments, fan-shaped moisture absorption areas 4102 and desorption areas 4101 can more effectively and rationally utilize space.

[0111] In some embodiments, the moisture absorption and dehumidification member 42 is disposed in the moisture absorption and dehumidification housing 41, as long as it can perform the moisture absorption and dehumidification function. The shape of the moisture absorption and dehumidification member 42 is not limited, and can be a polygon such as a triangle or a square, or a roulette shape, such as Figure 16 and Figure 18 As shown, the roulette-shaped moisture absorption and dehumidification component 42 is designed to make the moisture absorption and dehumidification component 42 circulate between the moisture absorption zone 4102 and the desorption zone 4101. The part of the moisture absorption and dehumidification component 42 that moves to the moisture absorption zone 4102 (that is, the moisture absorption part 4201) absorbs moisture in the air, and then the part of the moisture absorption and dehumidification component 42 that has absorbed moisture moves to the desorption zone 4101 to desorb moisture, and the part of the moisture absorption and dehumidification component 42 that has desorbed moisture (that is, the desorption part 4202) moves to the moisture absorption zone 4102 again to absorb moisture, so that the moisture in the air is removed in this cyclical manner, thereby achieving the effect of moisture absorption and dehumidification.

[0112] In some embodiments, the moisture absorption and dehumidification component 42 is a dehumidification turntable component. The dehumidification turntable in the dehumidification turntable component can be a honeycomb or corrugated turntable carrying a desiccant, which can adsorb and desorb / desorb the absorbed water vapor to achieve repeated desorption and regeneration. In some embodiments, the dehumidification turntable includes an inorganic / organic fiber carrier, such as ceramics, glass fiber, MOFs (Metal-Organic Frameworks, metal-organic framework materials), COFs (Covalent-Organic Frameworks, covalent organic framework materials), cordierite, etc. The fiber carrier is coated with a desiccant such as a molecular sieve, and the desiccant is evenly distributed between the fiber carriers and on the surface of the fiber carrier to achieve adsorption of moisture in the airflow. The desiccant can be, for example, zeolite, modified / synthetic zeolite, molecular sieve (including but not limited to single crystal molecular sieves or mixed crystal molecular sieves such as type A molecular sieve, type X / Y molecular sieve, ZSM molecular sieve, Beta molecular sieve, etc.), polymer desiccant, alkali metal aluminosilicate (13X molecular sieve), lithium chloride, silica gel, modified silica gel, activated alumina and other materials with hygroscopic properties.

[0113] In an optional embodiment, the moisture absorption and dehumidification component 42 is a molecular sieve dehumidification rotary disk.

[0114] In one embodiment, the regeneration component 44 is a heating element for heating the air in the desorption zone 4101. In one embodiment, the regeneration component 44 includes an electric heating element.

[0115] Then, please refer to Figure 6 、 Figure 7 and Figure 8As shown, in one embodiment, the heat pump system 3 further includes a third heat exchanger 33, which is connected in series between the throttling device 36 and the first heat exchanger 32 or between the first heat exchanger 32 and the compressor 31. The third heat exchanger 33 serves as another cold source for cooling, condensing, and dehumidifying the high-temperature air after the desorption unit 4202, thereby reducing the absolute humidity of the air after the desorption unit 4202.

[0116] By using the third heat exchanger 33 as a cold source for the moisture absorption and dehumidification system 4, internal heat circulation during the regeneration process of the moisture absorption and dehumidification system 4 can be further achieved, thereby preventing high-temperature air from being discharged outside the device housing 1. The applicability of the clothing processing device 200 is wider.

[0117] In one embodiment, the third heat exchanger 33 includes a second evaporator.

[0118] In one embodiment, based on the design of the base assembly 11 and the arrangement of the heat pump system 3 on the base assembly 11, the third heat exchanger 33 is connected in series between the throttling device 36 and the first heat exchanger 32. Figure 6 and Figure 7 That is, the compressor 31, the second heat exchanger 34, the throttling device 36, the third heat exchanger 33 and the first heat exchanger 32 are connected in sequence along the direction in which the refrigerant flows out.

[0119] In other optional embodiments, based on the design of the base assembly 11 or other design requirements, the compressor 31, the second heat exchanger 34, the throttling device 36, the first heat exchanger 32, and the third heat exchanger 33 may be connected sequentially along the refrigerant outflow direction. In other optional embodiments, based on the design of the base assembly 11 or other design requirements, the third heat exchanger 33 may be connected in parallel with the first heat exchanger 32 and downstream of the throttling device 36; alternatively, the throttling device 36 may include two parallel throttling devices, one throttling device connected in series with the first heat exchanger 32 and the other throttling device connected in series with the third heat exchanger 33, with the first heat exchanger 32 and the third heat exchanger 33 connected in parallel.

[0120] See also Figure 6 As shown, the base assembly 11 is further provided with a regeneration duct. The regeneration duct is formed by at least a connection between the desorption zone 4101 within the moisture absorption and desorption housing 41 and the first duct portion 1111. The regeneration duct is used to accommodate the desorption portion 4202 of the moisture absorption and desorption element 42 and the third heat exchanger 33. The regeneration duct is functionally independent and structurally isolated from the main drying duct 110.

[0121] Next, the base assembly 11 and the arrangement of the heat pump system 3 on the base assembly 11 will be described in detail.

[0122] See also Figure 5 、 Figure 6 、 Figure 11 and Figure 12 As shown, the base assembly 11 includes a base 12 and an upper cover 13. Figure 5 and Figure 6 As shown, the base 12 includes a bottom plate 120 and a first side plate 121 arranged on the upper surface of the bottom plate 120. The upper cover 13 is connected to the end surface of the first side plate 121 facing away from the bottom plate 120, that is, the upper end surface of the first side plate 121, to define the above-mentioned main drying air duct 110.

[0123] In an optional embodiment, if Figure 7 and Figure 16 As shown, at least a portion of the moisture absorption and dehumidification housing 41 and the moisture absorption and dehumidification element 42 are disposed within the main drying duct 110, and the rotational axis of the moisture absorption and dehumidification element 42 is parallel to the wind direction within the main drying duct 110. It should be understood that the rotational axis of the moisture absorption and dehumidification element 42 is not parallel to the wind direction at any position within the main drying duct 110, but rather is parallel to the wind direction within at least the portion of the main drying duct 110 where the moisture absorption and dehumidification element 42 is disposed. In other words, air passing through the moisture absorption and dehumidification element 42 flows straight within the main drying duct 110.

[0124] The purpose of this arrangement is that the air flows straightly in at least part of the main drying duct 110 where the moisture absorption and dehumidification component 42 is arranged, thereby reducing the possibility of air reversal and vortex generation. The drying module 100 has high air flow efficiency and low wind resistance. No complex isolation and sealing structure is required between the main drying duct 110 and the moisture absorption and dehumidification system 4. The clothing processing device 200 also has the advantages of fast drying speed and low energy consumption.

[0125] See also Figure 5 and Figure 6 As shown, in one embodiment, the base 12 further includes a second side plate 122 disposed on the upper surface of the bottom plate 120 and located next to the first side plate 121. The upper cover 13 is also connected to the upper end surface of the second side plate 122 to define a first air duct portion 1111 of the regeneration air duct.

[0126] In one embodiment, a second air channel portion is provided in the moisture absorption and dehumidification housing 41 disposed in the main drying air channel 110. The first air channel portion 1111 is connected to the second air channel portion and forms a regeneration air channel. The first air channel portion 1111 is used to house the second heat exchanger 34.

[0127] It can be understood that, as far as the base assembly 11 is concerned, there is no need to set up an obvious dividing structure in the main drying air duct 110 to divide the part for accommodating the moisture absorption and dehumidification shell 41. Instead, the moisture absorption and dehumidification shell 41 itself is set in the main drying air duct 110 to define another part of the regeneration air duct, namely the desorption zone 4101.

[0128] The first heat exchanger 32 and the second heat exchanger 34 are arranged in the main drying air duct 110, that is, arranged on the upper surface of the bottom plate 120, and condensed water is generated around the first heat exchanger 32. Therefore, in one embodiment, please refer to Figure 11 and Figure 12 As shown, a water channel 113 located in the main drying air duct 110 is provided on the bottom plate 120 , or in other words, the condensed water will drip onto the upper surface of the bottom plate 120 , and the partial space below the main drying air duct 110 can be used as the water channel 113 .

[0129] like Figure 5 、 Figure 6 and Figure 11 As shown, the bottom plate 120 includes a water collecting box 123 located outside the first side plate 121, and a first drain port 1210 is provided on the first side plate 121 and / or the bottom plate 120. The first drain port 1210 connects the water collecting box 123 with the water passage 113. Figure 11 As shown, the bottom surface of the water channel 113 (i.e., the upper surface of the portion of the bottom plate 120 located in the main drying air duct 110) gradually decreases in the direction toward the first drain port 1210. In this way, the condensed water automatically flows toward the first drain port 1210 and enters the water collection box 123.

[0130] The water collection box 123 can be configured as a detachable water collection structure such as a drawer type or a screw type, and can also be discharged into a sewer through a water pipe.

[0131] like Figure 12 As shown, the third heat exchanger 33 in the first air duct section 1111 also produces condensed water, which drips onto the upper surface of the bottom plate 120 located in the first air duct section 1111, or in other words, the partial space below the first air duct section 1111 also serves as the water passage 113. A second drain port 1220 is provided on the second side plate 122 and / or the bottom plate 120. In the first air duct section 1111, the upper surface of the bottom plate 120 gradually decreases in the direction toward the second drain port 1220, and the second drain port 1220 is connected to the water collection box 123. In an optional embodiment, according to the positional relationship between the first air duct section 1111 and the main drying air duct 110, the first drain port 1210 can be connected to the main drying air duct 110 and the first drain port 1210 in sequence.

[0132] See also Figure 6 、 Figure 11 and Figure 12As shown, in one embodiment, the base assembly 11 further includes an isolation plate 14 disposed within the main drying air duct 110. The isolation plate 14 is spaced apart from the upper surface of the bottom plate 120 to form a water passage 113. At least one drainage hole 141 is provided on the isolation plate 14 at a position corresponding to the first heat exchanger 32. This allows the first and second heat exchangers 32, 34 to be supported on the isolation plate 14, and condensed water generated on the first heat exchanger 32 can enter the water passage 113 through the drainage hole 141.

[0133] like Figure 6 、 Figure 11 and Figure 12 As shown, in one embodiment, a plurality of raising blocks 124 are provided on the upper surface of the bottom plate 120. The raising blocks 124 are used to support the isolation plate 14 at a certain height. That is, the isolation plate 14 is provided on the end surface of the raising blocks 124 facing the upper cover 13. In order to evenly support the isolation plate 14 at multiple positions, the raising blocks 124 are designed in different shapes and positions. For example, referring to Figure 6 As shown, a portion of the raising blocks 124 (the first raising block 1241) is arranged on the inner wall of the first side panel 121 to support the edge of the isolation plate 14, and another portion of the raising blocks 124 (a plurality of second raising blocks 1242) is arranged at intervals in the water channel 113 and the main drying air duct 110 to provide multi-point support to the middle of the isolation plate 14.

[0134] like Figure 11 and Figure 12 As shown, in one embodiment, a portion of the raising blocks 124 (third raising blocks 1243) are mutually enclosed in the water passage 113 and define a first installation cavity 1240. The first installation cavity 1240 is configured to accommodate a portion of the moisture absorption and dehumidification system 4, specifically, a portion of the moisture absorption and dehumidification housing 41. The isolation plate 14 is provided with an avoidance opening 143 corresponding to the first installation cavity 1240, as shown in FIG. Figure 6 As shown, the moisture absorption and dehumidification system 4 can be partially located above the isolation plate 14 and partially located below the isolation plate 14, and can be isolated from the water channel 113. The purpose of this arrangement is to allow the moisture absorption and dehumidification system 4 to be as close to the bottom plate 120 as possible in the vertical direction, thereby lowering the position of the moisture absorption and dehumidification system 4 and, in turn, reducing the overall height of the clothing processing device 200.

[0135] In an optional embodiment, if permitted, the lower surface of the bottom plate 120 may protrude downward corresponding to the first installation cavity 1240, and the upper surface of the bottom plate 120 may be recessed downward corresponding to the first installation cavity 1240, such as Figure 11 and Figure 12 As shown, the position of the moisture absorption and dehumidification system 4 can be further lowered.

[0136] See also Figure 11 As shown, the upper surface of the isolation plate 14 corresponding to the first heat exchanger 32 is designed as a downwardly facing concave surface, with at least some of the drainage holes 141 disposed on the concave surface. This design is intended to better direct water dripping from the first heat exchanger 32 toward the drainage holes 141, and then through the drainage holes 141 into the water channel 113 below the isolation plate 14.

[0137] In addition, condensed water is also generated around the first heat exchanger 32. Therefore, in one embodiment, please refer to Figure 6 and Figure 11 As shown, a water retaining bar 142 is provided on the upper surface of the isolation plate 14. The water retaining bar 142 is located on the side of the first heat exchanger 32 close to the moisture absorption and dehumidification system 4 and is spaced a certain distance from the first heat exchanger 32. The leakage hole 141 and the avoidance port 143 are respectively located on opposite sides of the water retaining bar 142. The purpose of this arrangement is that, since the wind direction is from the first heat exchanger 32 to the moisture absorption and dehumidification system 4, significant condensation water will also be generated in part of the space downstream of the first heat exchanger 32. The water retaining bar 142 can block this part of the condensation water outside the avoidance port 143, thereby preventing the condensation water from entering the avoidance port 143 and the first installation cavity 1240. According to the height relationship between the above-mentioned concave surface and the water retaining bar 142, one or more water retaining holes 141 can be provided on the side of the water retaining bar 142 close to the first heat exchanger 32, such as Figure 6 shown.

[0138] See also Figure 6 and Figure 12 As shown, in one embodiment, a downwardly extending rib 144 is formed on the isolation plate 14 at the periphery of the avoidance opening 143. The rib 144 can optionally be a closed enclosure. Therefore, the rib 144 is located within the first installation cavity 1240. The purpose of this arrangement is to guide the moisture absorption and dehumidification system 4 during assembly. In addition, the interference fit between the rib 144 and the first gasket further prevents condensed water in the water channel 113 from entering the first installation cavity 1240.

[0139] In one embodiment, the isolation plate 14 can be fixedly connected to at least one of the spacer blocks 124 by fasteners, for example, the isolation plate 14 can be fixedly connected to the third spacer block 1243 by fasteners. The fasteners can be bolts, screws, etc., or other fixing structures.

[0140] In one embodiment, at least one of the raising blocks 124 is connected to the lower surface of the isolation plate 14 via a position-limiting mating structure. For example, the upper surface of at least the first raising block 1241 is provided with a position-limiting structure (not shown), and the lower surface of the isolation plate 14 is provided with a mating structure (not shown) that matches the position-limiting structure. The position-limiting structure can be a groove or a protrusion, and the mating structure can be a protrusion or a groove. The concave-convex mating between the upper surface of the first raising block 1241 and the lower surface of the isolation plate 14 can further ensure the installation stability of the isolation plate 14 on the raising block 124.

[0141] In other embodiments, other raising blocks 124 may also be connected to the isolation plate 14 via fasteners and / or position-limiting structures. For example, the third raising block 1243 may be connected to the isolation plate 14 via fasteners, or the second raising block 1242 may be connected to the isolation plate 14 via a position-limiting structure.

[0142] See also Figure 13 As shown, in one embodiment, the upper end surfaces of the first side panel 121 and the second side panel 122 are connected to the lower end surface of the upper cover 13 via a sealing structure 131. The sealing structure 131 includes a sealing protrusion 1311 and a sealing groove 1312. For example, the upper end surfaces of the first side panel 121 and the second side panel 122 are provided with one of the sealing groove 1312 and the sealing protrusion 1311, and the lower end surface of the upper cover 13 is provided with the other of the sealing groove 1312 and the sealing protrusion 1311, and the sealing protrusion 1311 is located in the sealing groove 1312. In an optional embodiment, a sealing member (not shown), such as an elastic sealing strip, is provided between the sealing protrusion 1311 and the sealing groove 1312.

[0143] In addition, the first side panel 121, the second side panel 122, and the upper cover 13 are detachably connected. Specifically, the first side panel 121, the second side panel 122, and the upper cover 13 are fastened together by fasteners (such as screws and bolts) to maintain the seal between the sealing groove 1312 and the sealing protrusion 1311, thereby ensuring the seal between the first side panel 121, the second side panel 122, and the upper cover 13. In other optional embodiments, the first side panel 121, the second side panel 122, and the upper cover 13 may be connected together by other detachable means.

[0144] like Figure 6 As shown, the second side plate 122 is connected to a portion of the first side plate 121, or in other words, a portion of the first side plate 121 is used to enclose the second side plate 122 to define the first air duct portion 1111. Figure 6 and Figure 7As shown, the first side panel 121 is provided with a first communication port 1211 and a second communication port 1212. The first communication port 1211 connects the main drying air duct 110 and the first air duct portion 1111. The second side panel 122 is provided with a third communication port 1221. Both the second communication port 1212 and the third communication port 1221 are in communication with the accommodating chamber 112. The first communication port 1211 is used to connect the first heat exchanger 32 with the desorption zone 4101 of the moisture absorption and dehumidification housing 41 along the wind direction. The second communication port 1212 and the third communication port 1221 are used to connect the first heat exchanger 32 with the regeneration assembly 44 along the wind direction.

[0145] Please refer to Figure 4 As shown, the first driving member 5 is used to drive the drum 2 to rotate. The first driving member 5 may specifically include a first motor, a synchronous wheel, and a first synchronous belt (not shown). The first motor drives the synchronous wheel to rotate, and the synchronous wheel drives the synchronous belt to rotate. The synchronous belt is sleeved on the outer circumference of the drum 2 to drive the drum 2 to rotate synchronously.

[0146] In one embodiment, the first driving member 5 may include a second synchronous belt, a connecting arm, and a tensioning member (none of which are shown). The connecting arm is movably mounted on the first motor and connected to a synchronous pulley. The second synchronous belt is connected between the synchronous pulley and the drive shaft of the first motor. One end of the tensioning member is connected to the synchronous pulley and the other end is connected to the base plate 120 to tension at least the second synchronous belt. The tensioning member may specifically be a spring, a tension rope, or the like.

[0147] like Figure 8 As shown, in one embodiment, a mounting portion 127 is provided on the base plate 120, and a chamfered arc surface 1270 is provided on the protrusion on the inner side of the mounting portion 127 on the base plate 120. Typically, due to the positional relationship between the tensioning member and the synchronous wheel, the tensioning member is tilted relative to the vertical direction and the horizontal direction. The chamfered arc surface 1270 is used to avoid the tensioning member and prevent the right-angled surface from interfering with the elastic expansion and contraction of the tensioning member.

[0148] The rear side of the base 12 is used to connect with the rear side plate. Figure 9 As shown, in one embodiment, the edge of the bottom plate 120 is provided with a plurality of guide blocks 126. The guide blocks 126 are located on the periphery of the first side plate 121. The side of the guide blocks 126 facing the first side plate 121 has a guide surface 1260. The guide surface 1260 is inclined toward the first side plate 121 in the direction from the upper cover 13 to the bottom plate 120. Thus, when installing the rear side plate, the rear side plate is aligned with the guide blocks 126 and moved from top to bottom. The rear side plate slides along the guide surfaces 1260 and enters the front side of the guide blocks 126, achieving rapid positioning and pre-fixed connection between the rear side plate and the base 12.

[0149] See also Figure 6 、 Figure 7 and Figure 11 As shown, in one embodiment, the base 12 further includes a third side plate 125 disposed on the bottom plate 120 and located outside the first side plate 121 and the second side plate 122. The third side plate 125 encloses and defines a front air duct 1250; Figure 11 As shown, the third side panel 125 is provided with a fourth connecting port 1251 connected to the main drying air duct 110 , and the end surface of the third side panel 125 facing away from the bottom plate 120 defines a fifth connecting port 1252 , and the second connecting port 1212 is used to connect with the air outlet 23 of the drum 2 .

[0150] In one embodiment, please refer to Figure 2 and Figure 3 As shown, a third opening 161 is provided on the first support member 16 corresponding to the air inlet 21 of the drum 2. This third opening 161 is connected to and aligned with the air inlet 21 in the axial direction of the drum 2. During the rotation of the drum 2, the air inlet 21 remains connected to the third opening 161. This third opening 161 is also connected to the front air duct 1250, thereby connecting the laundry processing space 22 of the drum 2 to the front air duct 1250.

[0151] Please refer to the following for details: Figure 2 and Figure 3 As shown, a filter duct 160 is provided on the inner circumferential wall of the third opening 161 on the first support member 16. The filter duct 160 is connected between the front duct 1250 and the third opening 161. This allows communication between the third opening 161 and the front duct 1250. Optionally, a filter device (not shown) may be provided within the filter duct 160 to filter clothing debris and the like carried by the air flowing out of the drum 2. Optionally, a filter device may also be provided within the front duct 1250. Filter devices include, but are not limited to, filter boxes, filter plates, and the like.

[0152] Reference Figure 2 and Figure 3 As shown, the first support member 16 is disposed above the third side plate 125. The filter air duct 160 and the front air duct 1250 are substantially aligned and connected in the vertical direction.

[0153] See also Figure 6 and Figure 12 As shown, in one embodiment, the upper cover 13 is provided with a first wire hole 132. The first wire hole 132 is used for passing power lines, signal lines, etc. In some embodiments, the regeneration component 44 includes a heating element 441, please refer to Figure 16 and Figure 17 As shown, the heating element 441 is specifically an electric heating element. In this case, the power supply line is used to provide electrical energy to the electric heating element.

[0154] like Figure 6 and Figure 12As shown, a plurality of spaced apart wire fixing blocks 133 are provided at the edge of the upper cover 13. The wire fixing blocks 133 are used to fix the power lines, signal lines, etc. passing through the first wire holes 132. The form of the wire fixing blocks 133 is not limited.

[0155] See also Figure 4 As shown, in one embodiment, the clothing processing device 200 also includes a main circulation fan 6, which is at least partially arranged in the main drying duct 110. The first driving member 5 is connected to the main circulation fan 6 to drive the main circulation fan 6 to rotate, and the main circulation fan 6 is used to drive the air flow in the main drying duct 110.

[0156] In one embodiment, if Figure 4 As shown, the main circulation fan 6 is arranged downstream of the second heat exchanger 34 , and is used to transport the air in the main drying air duct 110 to the air inlet 21 of the drum 2 .

[0157] In one embodiment, the first drive member 5 is a dual-drive member, such as a dual-rotor motor, having a first drive shaft and a second drive shaft (not shown). The second drive shaft is used to drive the drum 2, and the first drive shaft is used to connect to the main circulation fan 6. In this way, a single first drive member 5 can provide operation for the drum 2 and the main circulation fan 6, saving structural costs and reducing space.

[0158] Please continue reading Figure 6 and Figure 12 As shown, the main circulation fan 6 is arranged between the upper cover 13 and the first side panel 121, and a mounting position 135 for mounting the main circulation fan 6 is provided on the upper cover 13 and / or the first side panel 121. For example, the mounting position 135 can be a mounting hole defined by the upper cover 13 and / or the first side panel 121. In order to adapt to the shape of the main circulation fan 6 and to reduce the height of at least the position corresponding to the main circulation fan 6 on the base assembly 11 as much as possible, in one embodiment, one or more reinforcing ribs 134 are provided on the upper surface of the upper cover 13 corresponding to the main circulation fan 6, so as to ensure the strength of the upper cover 13 while making the upper cover 13 as thin as possible.

[0159] In one embodiment, any one of the base 12, the isolation plate 14, and the upper cover 13 can be a plastic component, for example, an integral structure formed by injection molding. Furthermore, the plastic base 12, isolation plate 14, and upper cover 13 have low thermal conductivity, resulting in low heat exchange with the air in the main drying duct 110 and the regeneration duct.

[0160] Next, see Figure 6 、 Figure 7 and Figure 10As shown, in the heat pump system 3 , the compressor 31 , the second heat exchanger 34 , the throttle, the third heat exchanger 33 and the first heat exchanger 32 are sequentially connected through the refrigerant pipe 35 .

[0161] During the operation of the compressor 31, the refrigerant is continuously sucked in and discharged, and therefore, the compressor 31 will vibrate. Generally speaking, the vibration is mostly manifested as multi-directional vibration in the horizontal plane. In order to reduce the pulling and squeezing of the refrigerant pipe 35 during the vibration of the compressor 31 and avoid the refrigerant pipe 35 from breaking, especially the part of the refrigerant pipe 35 close to the compressor 31, such as Figure 10 As shown, in one embodiment, the refrigerant pipe 35 includes multiple pipe segments 351, and adjacent pipe segments 351 are bent relative to each other in the horizontal direction and / or vertical direction. For example, when the compressor 31 vibrates in the left-right direction, and the first pipe segment 351 connected to the compressor 31 also extends in the left-right direction, the first pipe segment 351 will move in the left-right direction, and the second pipe segment 351 will deflect and bend in the left-right direction. For the pipe segments 351 that are connected in sequence and are slender (the length is greater than the outer diameter), the risk of breakage caused by deflection and bending is significantly reduced compared to pulling and squeezing along the length direction. When multiple pipe segments 351 are bent and connected in sequence, the pulling and squeezing of the refrigerant pipe 35 caused by the vibration of the compressor 31 will be significantly reduced.

[0162] Adjacent pipe sections 351 are relatively bent and connected in the horizontal direction, which means that the projections of adjacent pipe sections 351 on the horizontal plane or on the base plate 120 are bent and connected; adjacent pipe sections 351 are relatively bent and connected in the vertical direction, which means that the projections of adjacent pipe sections 351 in the vertical plane are bent and connected.

[0163] In one embodiment, the refrigerant pipe 35 is a copper pipe. Copper pipe has good ductility, which facilitates the production of multiple relatively curved pipe segments 351. Furthermore, adjacent pipe segments 351 can be connected with smooth transitions to reduce resistance to refrigerant flow between the pipe segments 351 and facilitate assembly of the laundry processing device 200.

[0164] See also Figure 6 and Figure 8As shown, in one embodiment, the housing of the compressor 31 is provided with a plurality of first fixing ears 311, each of which is provided with a fixing hole 3110. A first fastener 37 is disposed within the fixing hole 3110 and connected to the base plate 120. The outer diameter of the first fastener 37 is smaller than the inner diameter of the fixing hole 3110. This creates an annular gap around the first fastener 37. This arrangement is intended to accommodate the vibration of the compressor 31 as described above. If the first fixing ears 311 and the first fastener 37 are fixedly connected without a gap, continuous vibration of the compressor 31 could damage the first fixing ears 311 of the compressor 31, or even the housing of the compressor 31. This could also cause vibration of the base plate 120, the entire base 12, and the base assembly 11. In this embodiment, the vibration of the compressor 31 is transmitted to the refrigerant pipe 35, where it is buffered and dissipated by the bent pipe section 351. This reduces damage to the compressor 31 itself and mitigates the overall vibration of the laundry processing device 200.

[0165] In an alternative embodiment, see Figure 10 As shown, in the heat pump system 3, a plurality of sequentially connected pipe segments 351 define an escape space 350, which is used to accommodate the first drive member 5. This arrangement is intended to ensure that both the refrigerant pipe 35 and the first drive member 5 are disposed within the accommodating cavity 112 of the base plate 120. The refrigerant pipe 35 must escape the first drive member 5. Optionally, at least a portion of the refrigerant pipe 35 is positioned below the first drive member 5 to avoid affecting the connection between the first drive member 5 and the drum 2. Therefore, the escape space 350 is defined by the portion of the pipe segment 351 positioned below the first drive member 5 and the portion of the pipe segment 351 positioned around the first drive member 5, adapted to the shape of the first drive member 5.

[0166] Next, the moisture absorption and dehumidification system 4 according to an embodiment of the present application is introduced.

[0167] See also Figure 15 、 Figure 16 、 Figure 17 and Figure 22 As shown, in one embodiment, in the moisture absorption and dehumidification system 4, a first opening 4110 is provided on the moisture absorption and dehumidification shell 41. Figure 14 、 Figure 16 and Figure 22As shown, the moisture absorption and dehumidification housing 41 is further provided with a second opening 4120. The first opening 4110 and the second opening 4120 respectively expose a portion of the surface of the moisture absorption and dehumidification member 42, so that the first opening 4110 and the second opening 4120 are connected via the moisture absorption portion 4201 of the moisture absorption and dehumidification member 42. Air sequentially passes through the passage formed by the first opening 4110, the moisture absorption portion 4201, and the second opening 4120, and moisture in the air is absorbed by the moisture absorption portion 4201. The portion of the moisture absorption and dehumidification housing 41 corresponding to the first opening 4110 and the second opening 4120 is referred to as the moisture absorption zone 4102.

[0168] In an alternative embodiment, see Figure 14 、 Figure 16 and Figure 22 As shown, the first opening 4110 is formed on the first axial end surface of the moisture absorption and dehumidification housing 41, and the first opening 4110 exposes a portion of the first axial end surface of the moisture absorption and dehumidification member 42. This allows the first opening 4110 to be manufactured in a simple manner and have a larger area, thereby increasing the air flow area of ​​the moisture absorption portion 4201 and improving the moisture absorption efficiency within the moisture absorption portion 4201.

[0169] In an alternative embodiment, see Figure 15 、 Figure 16 、 Figure 17 and Figure 22 As shown, the second opening 4120 is formed on the second axial end surface of the moisture absorption and dehumidification shell 41, and the second opening 4120 exposes a portion of the second axial end surface of the moisture absorption and dehumidification member 42. Similarly, this allows the second opening 4120 to be manufactured in a simple manner and have a larger area, thereby increasing the air flow area of ​​the moisture absorption portion 4201 and improving the moisture adsorption efficiency within the moisture absorption portion 4201.

[0170] In an alternative embodiment, see Figure 16 、 Figure 21 and Figure 22 As shown, the first opening 4110 is provided on a first axial end surface of the moisture absorption and dehumidification housing 41, and the second opening 4120 is provided on a second axial end surface of the moisture absorption and dehumidification housing 41. Overall, the moisture absorption and dehumidification housing 41 and the moisture absorption and dehumidification element 42 have a larger airflow area, which helps improve moisture adsorption efficiency, reduce air kinetic energy consumption, reduce energy consumption, and improve drying efficiency.

[0171] Alternatively, see Figure 16 、 Figure 17 and Figure 22As shown, the first opening 4110 and the second opening 4120 are axially connected through the moisture absorption portion 4201 of the moisture absorption and dehumidification member 42. Thus, the first opening 4110 and the second opening 4120 are aligned and connected along the axial direction of the moisture absorption and dehumidification member 42. Air passes axially through the moisture absorption and dehumidification member 42, which has a larger airflow area and adsorption area, and exhibits lower air resistance. This helps increase the air flow rate within the moisture absorption and dehumidification system 4, thereby improving moisture desorption efficiency and reducing energy consumption.

[0172] In one embodiment, the first and second axial end surfaces of the moisture absorption and dehumidification member 42 are both circular. The first opening 4110 and the second opening 4120 are both fan-shaped. Optionally, the areas of the first opening 4110 and the second opening 4120 are both greater than 50% of the area of ​​the axial end surface of the moisture absorption and dehumidification member 42. Further, optionally, the areas of the first opening 4110 and the second opening 4120 are both greater than 60% of the area of ​​the axial end surface of the moisture absorption and dehumidification member 42. Further, optionally, the areas of the first opening 4110 and the second opening 4120 are both greater than 70% of the area of ​​the axial end surface of the moisture absorption and dehumidification member 42. Further, optionally, the areas of the first opening 4110 and the second opening 4120 are both greater than 80% of the area of ​​the axial end surface of the moisture absorption and dehumidification member 42. This ensures that both the first opening 4110 and the second opening 4120 have sufficient areas. At the same time, the moisture absorption and dehumidification member 42 can be designed with a smaller diameter and volume, which helps reduce the overall volume of the moisture absorption and dehumidification system 4 and the overall volume of the clothing processing device 200.

[0173] Please refer to Figure 7 As shown, in one embodiment, the first heat exchanger 32, the moisture absorption and dehumidification system 4, and the second heat exchanger 34 are sequentially arranged in the main drying air duct 110 along the axial direction of the moisture absorption and dehumidification component 42. Figure 7 The solid triangular arrows in the figure indicate wind direction. Within the main drying duct 110, at least the portion housing the first heat exchanger 32, the moisture absorption and dehumidification system 4, and the second heat exchanger 34 is generally a square space. This allows air to flow smoothly through the first heat exchanger 32, the moisture absorption and dehumidification system 4, and the second heat exchanger 34, preventing air reversal and eddy currents. This maximizes air flow efficiency between the first heat exchanger 32, the moisture absorption and dehumidification system 4, and the second heat exchanger 34. Furthermore, within the moisture absorption and dehumidification element 42, the air flow direction is completely parallel to the direction of the vents in the element 42. Air dried through the element 42 can exit directly, minimizing the loss of air kinetic energy and wind speed. Depending on specific needs, within the main drying duct 110, the first heat exchanger 32, the moisture absorption and dehumidification system 4, and the second heat exchanger 34 can be arranged at a predetermined distance along the axial direction of the element 42, or they can be arranged without any separation, as long as they do not affect their respective operations.

[0174] Please refer to Figure 16 、 Figure 17 、 Figure 21 and Figure 22 , the moisture absorption and moisture removal shell 41 includes a first shell 411 and a second shell 412, the first shell 411 and the second shell 412 are connected on both sides of the axial direction of the moisture absorption and moisture removal piece 42 to limit the moisture absorption and moisture removal piece 42 inside. The first opening 4110 is provided on the first shell 411, and the second opening 4120 is provided on the second shell 412. The first shell 411 and the second shell 412 can be connected by fasteners (such as bolts, screws) and the like. In addition, please refer to Figure 16 and Figure 17 , in an optional embodiment, according to the shape of the first shell 411 and the second shell 412, at positions where it is not convenient to set the fasteners, a ring-shaped connecting piece 414 can also be sleeved on the first shell 411 and the second shell 412 to achieve further fixed connection of the first shell 411 and the second shell 412.

[0175] Please refer to Figure 22 , the area of the first shell 411 avoiding the first opening 4110 and the area of the second shell 412 avoiding the second opening 4120 are communicated along the axial direction of the moisture absorption and moisture removal piece 42 to form a second air duct part, that is, the desorption area 4101 of the moisture absorption and moisture removal shell 41. In this way, the moisture absorption and moisture removal shell 41 is at least partially arranged in the main drying air duct 110, and the second air duct part in the moisture absorption and moisture removal shell 41 is communicated with the first air duct part 1111 outside the main drying air duct 110, thereby forming a regeneration air duct.

[0176] Please refer to Figure 22 , the first shell 411 forms an air outlet air duct part 4115, and the second shell 412 forms an air inlet air duct part 4125, the air inlet air duct part 4125 and the air outlet air duct part 4115 are communicated via the desorption part 4202 of the moisture absorption and moisture removal piece 42, and constitute the second air duct part described above. That is, in the regeneration air duct, the air in the second shell 412 passes through the desorption part 4202, enters the first shell 411, then reaches the third heat exchanger 33, and finally circulates back to the second shell 412.

[0177] The first opening 4110 is used for air inlet, and the second opening 4120 is used for air outlet. In this embodiment, the flow direction of the air in the desorption part 4202 is opposite to the flow direction in the moisture absorption part 4201, which is beneficial to improve the desorption efficiency.

[0178] In other optional embodiments, the air outlet duct portion 4115 can also be formed on the second shell 412, and the air inlet duct portion 4125 can be formed on the first shell 411, so that the air flow direction in the desorption portion 4202 is the same as the flow direction in the moisture absorption portion 4201; or, the first opening 4110 is used for air outlet, and the second opening 4120 is used for air intake, so that the air flow direction in the desorption portion 4202 is the same as the flow direction in the moisture absorption portion 4201.

[0179] See also Figure 14 、 Figure 16 and Figure 22 As shown, in one embodiment, the first shell 411 is provided with a first outer air guide surface 4114, and the first outer air guide surface 4114 is axially inclined to the moisture absorption and dehumidification component 42, specifically gradually inclined toward the desorption portion 4202 in the direction toward the central axis of the moisture absorption and dehumidification component 42.

[0180] The first outer air guide surface 4114 is used to guide the air in the main drying air duct 110 so that the air gradually concentrates into the first opening 4110 on the moisture absorption and dehumidification housing 41, thereby preventing vortexes from being generated when the air reaches the surface of the first housing 411. Figure 22 The solid triangle arrow in the figure indicates the wind direction. This can ensure the air flow speed in the main drying duct 110, ensure the water adsorption efficiency in the moisture absorption part 4201, reduce the energy consumption of the clothes processing device 200, and improve the drying efficiency of the clothes processing device 200.

[0181] In an alternative embodiment, see Figure 15 and Figure 16 As shown, the width of the first outer air guide surface 4114 gradually decreases toward the central axis of the moisture absorption and dissipation element 42. In other words, when viewed from the axial direction of the moisture absorption and dissipation element 42, the first outer air guide surface 4114 is fan-shaped, which corresponds to the fan-shaped shape of the first opening 4110.

[0182] Please continue reading Figure 16 、 Figure 17 and Figure 22 As shown, in one embodiment, the second housing 412 is further provided with a second outer air guide surface 4124. The second outer air guide surface 4124 is arranged to be inclined relative to the axial direction of the moisture absorption and dehumidification component 42. Specifically, the second outer air guide surface 4124 is gradually inclined toward the desorption portion 4202 in the direction toward the central axis of the moisture absorption and dehumidification component 42. The purpose of this arrangement is to guide the air in the main drying air duct 110 so that after flowing out of the second opening 4120, the air flows evenly toward the second heat exchanger 34, thereby avoiding the generation of vortexes between the second housing 412 and the second heat exchanger 34.

[0183] Further, the air flow speed in the main drying air duct 110 can be ensured, the moisture adsorption efficiency in the moisture absorption part 4201 can be ensured, the energy consumption of the clothes treatment equipment 200 can be reduced, and the drying efficiency of the clothes treatment equipment 200 can be improved.

[0184] In an optional embodiment, as shown in Figure 14 As shown in

[0185] As shown in Figure 16 and Figure 22 As shown in an embodiment, the inner wall of the first shell 411 is provided with a first inner air guide surface 4113, and the first inner air guide surface 4113 is arranged obliquely to the axial direction of the moisture absorption and removal part 42, specifically, gradually inclined to the desorption part 4202 in the direction toward the central axis of the moisture absorption and removal part 42. The first inner air guide surface 4113 is used to guide the air flowing out of the desorption part 4202 to change direction, so as to avoid vortex and wind energy loss caused by sharp change of direction when the air flows from the desorption part 4202 to the third heat exchanger 33. Optionally, the first outer air guide surface 4114 is generally parallel to the first inner air guide surface 4113.

[0186] Further, through the arrangement of the first inner air guide surface 4113, the air flow speed in the moisture absorption and removal system 4 can be ensured, the moisture desorption efficiency in the desorption part 4202 can be ensured, the energy consumption of the clothes treatment equipment 200 can be reduced, and the drying efficiency of the clothes treatment equipment 200 can be improved.

[0187] In an optional embodiment, the width of the first inner air guide surface 4113 gradually decreases in the direction toward the central axis of the moisture absorption and removal part 42. That is, as viewed in the axial direction of the moisture absorption and removal part 42, the first inner air guide surface 4113 is in the shape of a sector, which corresponds to the sector shape of the first opening 4110.

[0188] As shown in Figure 16 , Figure 17 and Figure 22 As shown in an embodiment, the inner wall of the second shell 412 is provided with a second inner air guide surface 4123, and the second inner air guide surface 4123 is arranged obliquely to the axial direction of the moisture absorption and removal part 42, specifically, gradually inclined to the desorption part 4202 in the direction toward the central axis of the moisture absorption and removal part 42. The second inner air guide surface 4123 is used to guide the air flowing out of the desorption part 4202 to change direction, so as to avoid vortex and wind energy loss caused by sharp change of direction when the air flows from the third heat exchanger 33 to the desorption part 4202. Optionally, the second outer air guide surface 4124 is generally parallel to the second inner air guide surface 4123.

[0189] In an alternative embodiment, see Figure 17 As shown, the width of the second inner air guide surface 4123 gradually decreases in the direction toward the central axis of the moisture absorption and dehumidification element 42. In other words, when viewed from the axial direction of the moisture absorption and dehumidification element 42, the second inner air guide surface 4123 is fan-shaped, which corresponds to the fan-shaped shape of the second opening 4120.

[0190] For one example, see Figure 22 As shown, a first inner wind guide surface 4113 is provided on the inner wall of the first shell 411, and a second inner wind guide surface 4123 is provided on the inner wall of the second shell 412. The first inner wind guide surface 4113 and the second inner wind guide surface 4123 are generally symmetrical about the radial plane of the moisture absorption and dehumidification component 42.

[0191] See also Figure 16 and Figure 17 As shown, in one embodiment, the heating element 441 of the regeneration assembly 44 is disposed within the second housing 412, that is, within the air inlet duct portion 4125, to heat the air entering the desorption portion 4202. Specifically, the heating element 441 can be an electric heating structure such as an electric heating tube or an electric heating plate, which is fixed to the inner wall surface of the second housing 412.

[0192] Please refer to Figure 16 As shown, the heating element 441 is fixed to the inner wall of the second housing 412 and spaced apart from the second inner air guide surface 4123. Air within the air inlet duct 4125 is guided by the second inner air guide surface 4123 before reaching the heating element 441 for heating. This arrangement places the heating element 441 closer to the surface of the desorption portion 4202 of the moisture absorption and desorption element 42, allowing heat to be more easily transferred to the moisture absorption and desorption element 42. This improves energy utilization and enhances the desorption efficiency of the desorption portion 4202.

[0193] Specific as Figure 17 As shown, the heating element 441 is fixed to the inner wall surface of the second housing 412 via a second fastener 413. The specific form of the second fastener 413 is not limited, as long as it can adapt to the structure of the heating element 441. For example, for an electric heating tube, the fastener can be adapted to the surface of the tube body of the electric heating tube. For example, for an electric heating plate, the fastener can be adapted to the plate surface.

[0194] See also Figure 17As shown, in one embodiment, the heating member 441 is fixed on the inner wall surface of the second housing 412 by a mounting plate 45. Since the heating member 441 is generally aligned with the second inner air guide surface 4123 in the axial direction, in order to keep the heating member 441 generally parallel to the axial surface of the moisture absorbing and removing member 42 so as to facilitate the uniform heating of the heating member 441 to the surface of the desorption portion 4202, a mounting plate 45 is provided to fix the heating member 441 and keep the orientation of the heating member 441. The mounting plate 45 can be in the form of a flat plate, and keep a large contact area between the heating member 441 to ensure the stability of the installation of the heating member 441.

[0195] As can be understood, Figure 17 the mounting plate 45 is in a porous structure so as not to affect the flow of air from the second inner air guide surface 4123 to the heating member 441.

[0196] Specifically, as shown in Figure 17 and Figure 22 in one embodiment, the second inner air guide surface 4123 is provided with a mounting platform 4121 protruding towards the first housing 411, the mounting plate 45 is arranged on the surface of the mounting platform 4121 facing the first housing 411, and the second fastener 413 passes through the mounting plate 45 and is fastened on the mounting platform 4121. In this way, the mounting plate 45 can be arranged spaced apart from the second inner air guide surface 4123, and the mounting position of the mounting plate 45 is provided.

[0197] The mounting platform 4121 is designed in a shape to reduce the space occupation in the air inlet duct portion 4125 and reduce the obstruction to the flow path of air. For example, the mounting platform 4121 is generally in the form of a thin plate, and the thickness direction is generally perpendicular to the air flow direction in the air inlet duct portion 4125, so the thickness is set to be small to reduce the obstruction to the air flow.

[0198] As shown in Figure 14 and Figure 21 the second housing 412 is provided with one or more second wire passing holes 4126 corresponding to the heating member 441. The heating member 441 is connected to the external power supply through the power supply wire, and the second wire passing hole 4126 is used for the power supply wire and the like to pass through.

[0199] As shown in Figures 14 to 17 the regeneration assembly 44 further comprises a regeneration fan 442, and the regeneration fan 442 is connected to the second housing 412. For example, the regeneration fan 442 can be arranged in the second housing 412, or connected to the end of the second housing 412 away from the second opening 4120. The regeneration fan 442 is used to provide the flow power of air in the regeneration air duct.

[0200] As shown in Figure 6 and Figure 7As shown, the regenerative blower 442 is arranged at the third communication opening 1221 of the second side plate 122 and is in communication with the first air duct portion 1111 inside the second side plate 122. The second shell 412 is in communication with the regenerative blower 442 via the second communication opening 1212.

[0201] As shown in Figs. 4 and 5, the moisture absorption and removal system 4 further comprises a second driving member 43 fixed on the moisture absorption and removal shell 41 and configured to drive the moisture absorption and removal member 42 to rotate. Figure 15 、 Figure 16 and Figure 20 As shown in Figs. 4 and 5, the moisture absorption and removal system 4 further comprises a second driving member 43 fixed on the moisture absorption and removal shell 41 and configured to drive the moisture absorption and removal member 42 to rotate.

[0202] In an optional embodiment, the rotation central axis of the moisture absorption and removal member 42 is parallel to the rotation central axis of the drum 2. The purpose of this arrangement is to facilitate the arrangement of structures in the equipment shell 1. Specifically, when the rotation central axis of the moisture absorption and removal member 42 is parallel to the rotation central axis of the drum 2, the portion of the main drying air duct 110 in which the first heat exchanger 32, the moisture absorption and removal system 4, and the second heat exchanger 34 are arranged is also parallel to the rotation central axis of the drum 2, i.e., the portion of the main drying air duct 110 in which the first heat exchanger 32, the moisture absorption and removal system 4, and the second heat exchanger 34 are arranged is arranged side by side with the drum 2 outside the drum 2. This achieves the maximum utilization of the space in the equipment shell 1 and is conducive to ensuring that the overall structure of the laundry treatment equipment 200 is compact and small in size.

[0203] In an embodiment, as shown in Figs. 4 and 5, the second driving member 43 is arranged on the first shell 411. Figure 15 and Figure 16 In an embodiment, as shown in Figs. 4 and 5, the second driving member 43 is arranged on the first shell 411.

[0204] Alternatively, the second driving member 43 is arranged on the side surface of the first shell 411 away from the second shell 412. That is, the second driving member 43 is arranged between the moisture absorption and removal member 42 and the first heat exchanger 32. The purpose of this arrangement is that the air flowing from the first heat exchanger 32 to the second driving member 43 is low-temperature air, and the second driving member 43 is in a low-temperature and low-humidity environment, which is conducive to reducing the influence of water vapor and high temperature on the second driving member 43 and ensuring the service life of the second driving member 43.

[0205] Moreover, the second driving member 43 and the heating member 441 are located on the axial two sides of the moisture absorption and removal member 42, which is conducive to balancing the volume and space on the axial two sides of the moisture absorption and removal system 4 and facilitating the flow of air on the axial two sides of the moisture absorption and removal system 4 in the main drying air duct 110 to be generally symmetrical, thereby reducing the pressure difference and air vortex caused by the imbalance of space. In addition, the second driving member 43 and the heating member 441 being located on the axial two sides of the moisture absorption and removal member 42 also helps to keep the weight balance on the axial two sides of the moisture absorption and removal system 4.

[0206] As mentioned above, the first opening 4110 and the second opening 4120 are both fan-shaped, which can expose more of the surface of the moisture absorption and dehumidification member 42 for moisture absorption. On this basis, in one embodiment, in the axial direction of the moisture absorption and dehumidification member 42, the second driving member 43 is offset from the first opening 4110, see Figure 15 As shown, the second driving member 43 is not aligned with the rotational axis of the moisture absorption and dehumidification member 42, but is offset from the first opening 4110 relative to the rotational axis. In other words, the second driving member 43 is radially offset from the first opening 4110 and is radially away from the first opening 4110. This arrangement is intended to reduce obstruction of the first opening 4110 by the second driving member 43 in the axial direction of the moisture absorption and dehumidification member 42, thereby reducing obstruction to the flow of air from the first heat exchanger 32 to the moisture absorption and dehumidification member 42, thereby increasing air velocity and improving drying efficiency.

[0207] See also Figure 20 As shown, in one embodiment, the second driving member 43 comprises a second motor 432. The second motor 432 is disposed offset from the first opening 4110 relative to the rotation center axis of the moisture absorption and discharge member 42.

[0208] In an optional embodiment, the second motor 432 comprises an eccentric motor, whose output shaft 4323 is coaxially connected to the moisture absorption and dehumidification component 42. This allows the second drive member 43 to be offset from the central axis of the moisture absorption and dehumidification component 42, but the output shaft 4323 of the second drive member 43 is aligned with the central axis of the moisture absorption and dehumidification component 42. This eliminates the need for a transmission assembly between the second drive member 43 and the moisture absorption and dehumidification component 42, simplifying the structure of the moisture absorption and dehumidification system 4. Furthermore, this eccentric arrangement reduces obstruction of the first opening 4110 by the second drive member 43, thereby increasing the airflow area of ​​the moisture absorption portion 4201 and improving drying efficiency.

[0209] In another embodiment, the output shaft 4323 of the second driving member 43 is connected to the moisture absorption and desorption member 42 via a transmission assembly (not shown). The output shaft 4323 of the second driving member 43 is further offset relative to the central axis of the moisture absorption and desorption member 42, away from the first opening 4110. This arrangement is intended to further reduce obstruction of the first opening 4110 by the second driving member 43. The first opening 4110 can be opened as close to the central axis of the moisture absorption and desorption member 42 as possible, or even completely clear the first opening 4110 from the second driving member 43.

[0210] See also Figure 20As shown, in one embodiment, the output shaft 4323 of the second driving member 43 has multiple flattened surfaces 43230, which are symmetrically distributed around the circumference. When the output shaft 4323 is connected to the moisture absorption and dehumidification member 42 and drives the moisture absorption and dehumidification member 42 to rotate, the driving force is evenly distributed across the multiple flattened surfaces 43230. This increases the driving contact area between the output shaft 4323 and the moisture absorption and dehumidification member 42, enabling the use of a smaller diameter output shaft 4323 to drive a larger moisture absorption and dehumidification member 42. Furthermore, wear and fatigue damage to both the output shaft 4323 and the moisture absorption and dehumidification member 42 can be reduced.

[0211] Except output shaft 4323, please refer to Figure 20 As shown, the second motor 432 also includes a motor housing 4321, a rotating assembly (not shown) disposed within the motor housing 4321, and an electronic control unit (not shown) disposed within the motor housing 4321 and connected to the rotating assembly. An output shaft 4323 passes through the motor housing 4321 and is connected to the rotating assembly. The electronic control unit is located on one side of the rotating assembly and is used to connect to an external power source and the rotating assembly. The motor housing 4321 is fixedly connected to the end face of the first housing 411 on the side facing away from the second housing 412.

[0212] For one example, see Figure 20 As shown, the outer surface of the motor housing 4321 is a non-circular surface, and the corresponding electric control part is convex outward to form a protrusion 4322. Based on the protrusion 4322, as shown in FIG. Figure 16 、 Figure 22 As shown, a limiting groove 4112 is provided on the first housing 411 corresponding to the protrusion 4322. The inner sidewall of the limiting groove 4112 is configured to abut against the limiting portion 4311 along the rotational direction of the moisture absorption and desorption member 42 to limit the rotation of the limiting portion 4311. In other words, the limiting groove 4112 and its limiting wall are configured to prevent the motor housing 4321 from rotating with the rotating assembly, thereby maintaining the motor housing 4321 fixed to the first housing 411. In an alternative embodiment, the inner walls of the limiting groove 4112 are provided on both circumferential sides of the protrusion 4322.

[0213] In one embodiment, please refer to Figure 20 As shown, the second driving member 43 further includes a sealed housing 431. The motor housing 4321 of the second motor 432 is disposed within the sealed housing 431. The sealed housing 431 is sealedly connected to the surface of the first housing 411 facing away from the second housing 412. By providing the additional sealed housing 431, the second motor 432 is completely protected and sealed therein, further reducing the impact of moisture in the main drying air duct 110 on the second driving member 43.

[0214] Specifically, if Figure 20As shown, a plurality of second fixing ears 4312 are provided on the sealing shell 431 , and the second fixing ears 4312 are fixedly connected to the surface of the first shell 411 through fasteners (bolts, screws, etc.).

[0215] Alternatively, as Figure 20 As shown, the second driving member 43 further includes a sealing gasket 434, which is disposed between the sealing housing 431 and a surface of the first housing 411 facing away from the second housing 412, and surrounds the output shaft 4323. The sealing housing 431 is fixed to the first housing 411 by fasteners (such as bolts, screws, etc.). The sealing gasket 434 is compressed between the sealing housing 431 and the first housing 411, thereby maintaining a sealed connection between the sealing housing 431 and the first housing 411 and further reducing the possibility of moisture entering the sealing housing 431.

[0216] Correspondingly, if Figure 20 As shown, the sealing housing 431 is provided with a stopper 4311 protruding outwardly corresponding to the protrusion 4322. The protrusion 4322 is located within the stopper 4311, and the stopper 4311 is located within the stopper groove 4112. The shape of the stopper groove 4112 is adapted to the shape of the stopper 4311, and the shape of the stopper 4311 is adapted to the shape of the protrusion 4322.

[0217] like Figure 16 and Figure 22 As shown, a motor mounting groove 4111 is axially recessed on the end surface of the first housing 411 facing away from the second housing 412, and faces the second housing 412. A portion of the sealing housing 431 and a sealing gasket 434 are disposed within the motor mounting groove 4111. This arrangement is intended to, on the one hand, ensure that the shape of the motor mounting groove 4111 matches the shapes of the sealing gasket 434 and the sealing housing 431, thereby facilitating rapid positioning of the second driving member 43 as a whole when installing the second driving member 43. Furthermore, the output shaft 4323 can be axially positioned as close as possible to the moisture absorption and dehumidification member 42, thereby minimizing deformation of the output shaft 4323, ensuring transmission efficiency between the output shaft 4323 and the moisture absorption and dehumidification member 42, and reducing wear on the output shaft 4323 and the moisture absorption and dehumidification member 42.

[0218] Next, see Figure 18 and Figure 19 As shown, the moisture absorption and moisture dissipation component 42 of the embodiment of the present application is introduced.

[0219] like Figure 18As shown, the moisture absorption and desorption member 42 includes a moisture absorption and desorption medium layer 421, a first fixing bracket 422, and a shaft 427. The moisture absorption and desorption medium layer 421 is fixed to the first fixing bracket 422, and the shaft 427 is fixedly passed through the first fixing bracket 422 and the moisture absorption and desorption medium layer 421. One end of the shaft 427 is also connected to the output shaft 4323 of the second driving member 43, so that the second driving member 43 can drive the moisture absorption and desorption medium layer 421 to rotate.

[0220] It can be understood that the first fixing bracket 422 is configured to be provided with air holes corresponding to the first opening 4110 and the second opening 4120 to expose a portion of the two axial end surfaces of the moisture absorption and dehumidification medium layer 421 .

[0221] In order to conveniently and effectively fix the moisture absorption and dehumidification medium layer 421 and make the area of ​​the air holes as large as possible, in one embodiment, the first fixing bracket 422 is covered on at least a portion of the outer peripheral surface of the moisture absorption and dehumidification medium layer 421 and abuts against at least one axial end surface of the moisture absorption and dehumidification medium layer 421.

[0222] In one embodiment, the first fixing bracket 422 is configured to cover at least a portion of the outer circumference of the moisture absorption and dehumidification medium layer 421 and abut at least the axial end surface of the moisture absorption and dehumidification medium layer 421 facing the first heat exchanger 32. This configuration is intended to allow the second driving member 43 to be positioned on the side of the moisture absorption and dehumidification medium layer 421 facing the first heat exchanger 32, thereby allowing the first fixing bracket 422 to connect the shaft 427 and the moisture absorption and dehumidification medium layer 421. This eliminates the need for the outer circumference of the shaft 427 to directly interact with the moisture absorption and dehumidification medium layer 421. Instead, the first fixing bracket 422 distributes the applied force to more locations within the moisture absorption and dehumidification medium layer 421, preventing the applied force from directly acting on the center of the moisture absorption and dehumidification medium layer 421 and potentially damaging it.

[0223] like Figure 18 As shown, in one embodiment, the first fixed bracket 422 includes a first plate body 4231, a first inner fixed portion 4241 and a plurality of connecting portions 4242. The first plate body 4231 is annular and abuts against at least a portion of the outer circumference of the moisture absorption and dehumidification medium layer 421. The inner fixed portion 4241 is arranged in the first plate body 4231 and abuts against the end surface of the moisture absorption and dehumidification medium layer 421 facing the first heat exchanger 32. The plurality of connecting portions 4242 are arranged at intervals along the circumferential direction and radially connect the first plate body 4231 and the inner fixed portion 4241. The shaft 427 is fixedly passed through the inner fixed portion 4241 and the moisture absorption and dehumidification medium layer 421.

[0224] The first plate 4231 is used to protect and abut at least a portion of the outer circumference of the moisture absorption and dehumidification medium layer 421. The inner fixing portion 4241 is used to connect to the shaft 427. The connecting portion 4242 securely connects the first plate 4231 and the inner fixing portion 4241 together, and the aforementioned air holes are formed between the connecting portions 4242. During the rotation of the moisture absorption and dehumidification element 42, the air holes are continuously connected to the first opening 4110 and the air outlet duct portion 4115.

[0225] like Figure 18 As shown, the inner fixing portion 4241 defines an axially extending connecting hole 42410. The inner circumferential wall of the connecting hole 42410 is provided with at least one notch 42411. The outer circumferential surface of the shaft member 427 is provided with a protrusion 4275 that engages with the notch 42411. In other words, the inner circumferential wall of the connecting hole 42410 and the outer circumferential surface of the shaft member 427 are not designed to be circular, but rather to form a concave-convex fit, forming a circumferentially fixed connection.

[0226] In one embodiment, in order to facilitate the production of the first fixing bracket 422, as shown in FIG. Figure 18 As shown, the first fixing bracket 422 includes a separate first fixing ring 423 and a bracket portion 424, that is, the first fixing ring 423 and the bracket portion 424 are manufactured separately. The first fixing ring 423 includes a first plate 4231 and a second plate 4232 connected to the first plate 4231. The second plate 4232 is used to abut the edge of the axial end surface of the moisture absorption and dehumidification medium layer 421 facing the first heat exchanger 32. The bracket portion 424 includes the aforementioned connecting portion 4242 and an inner fixing portion 4241. The radial outer edge of the connecting portion 4242 is located between the second plate 4232 and the moisture absorption and dehumidification medium layer 421. This facilitates the manufacture of the inner fixing portion 4241 and the connecting portion 4242, simplifying the structure of the first fixing ring 423 and also facilitating manufacture.

[0227] Furthermore, in order to facilitate the manufacture and installation of the bracket portion 424 and avoid bending and deformation of the radial outer ends of the plurality of spaced connecting portions 4242, in one embodiment, refer to Figure 18 As shown, the bracket portion 424 further includes a bracket outer ring 4243, which is connected between the radial outer ends of each connecting portion 4242, and the bracket outer ring 4243 is located between the second plate 4232 and the moisture absorption and moisture discharge medium layer 421, as shown in FIG. Figure 19 shown.

[0228] like Figure 18 and Figure 19As shown, a first recessed groove 42430 is formed at the outer edge of the bracket outer ring 4243, extending through the outer circumference of the bracket outer ring 4243. The second plate 4232 is disposed within the first recessed groove 42430. This arrangement serves the following purposes: firstly, the first recessed groove 42430 acts as a reinforcement structure, thereby increasing the overall strength of the bracket outer ring 4243 and preventing deformation thereof; secondly, on the side facing the first heat exchanger 32, the height difference between the bracket outer ring 4243 and the second plate 4232 can be minimized, and the plates can even be substantially flush.

[0229] Optionally, a concave-convex limiting structure (not shown) is provided on the outer circumferential surface of the bracket outer ring 4243, and a concave-convex limiting structure that matches it can also be designed on the inner circumferential surface of the first plate body 4231, so that the bracket outer ring 4243 and the first fixed ring 423 are easy to manufacture and maintain a fixed connection in the circumferential direction.

[0230] like Figure 18 As shown, a second recessed groove 42413 is provided on the inner fixing portion 4241. Similarly, the provision of the second recessed groove 42413 can enhance the strength of the inner fixing portion 4241 and reduce the risk of deformation of the inner fixing portion 4241.

[0231] like Figure 18 As shown, to reduce obstruction of the first opening 4110, the number of connecting portions 4242 should be as small as possible, and the circumferential width of the connecting portion 4242 should be as small as possible. On this basis, to improve the strength of each connecting portion 4242, each connecting portion 4242 is provided with a recessed area 42420. The recessed area 42420 serves as a reinforcement structure to improve the deformation resistance of the connecting portion 4242.

[0232] Further, see Figure 18 As shown, each connecting portion 4242 is provided with one or more radially spaced through holes 42421. On the basis of ensuring the anti-deformation capability of the connecting portion 4242, the provision of the through holes 42421 further increases the area of ​​the air holes on the first fixing bracket 422.

[0233] In particular, on each connecting portion 4242 , a plurality of through holes 42421 are arranged at intervals, so that the area of ​​each through hole 42421 can be smaller, and the deformation resistance of each connecting portion 4242 is improved.

[0234] See also Figure 18As shown, the shaft member 427 includes a coaxially connected first shaft segment 4271 and a second shaft segment 4273. The first shaft segment 4271 is provided with a radially extending first abutment portion 4272, and the second shaft segment 4273 is provided with a radially extending second abutment portion 4274. The first abutment portion 4272 and the second abutment portion 4274 are respectively located on opposite axial sides of the moisture absorption and desorption medium layer 421. The first shaft segment 4271 and the second shaft segment 4273 are manufactured separately and connected to the moisture absorption and desorption medium layer 421 from opposite axial sides. The first abutment portion 4272 and the second abutment portion 4274 abut against the opposite axial sides of the moisture absorption and desorption medium layer 421 over a large area, exerting a certain amount of compressive force on the moisture absorption and desorption medium layer 421.

[0235] like Figure 18 As shown, the shape of the second sink groove 42413 is designed to match the shape of the first abutting portion 4272 , and the first abutting portion 4272 is located in the second sink groove 42413 .

[0236] For one example, see Figure 18 As shown, the moisture absorption and dehumidification component 42 also includes a second fixed bracket 425, which is arranged on the side of the moisture absorption and dehumidification shell 41 facing the second shell 412. The second fixed bracket 425 is fixedly connected to the first fixed bracket 422. The second fixed bracket 425 is used to abut at least part of the outer peripheral surface of the moisture absorption and dehumidification medium layer 421 and the end surface on one side facing away from the first shell 411.

[0237] In this way, the first fixing bracket 422 and the second fixing bracket 425 can abut and press the two axial end surfaces of the moisture absorption and dehumidification medium layer 421 , and protect the outer peripheral surface of the moisture absorption and dehumidification medium layer 421 .

[0238] Specifically, see Figure 18 and Figure 19 As shown, the second fixed bracket 425 includes a third plate body 4251 and a fourth plate body 4252 connected to each other, the third plate body 4251 abuts against at least part of the outer peripheral surface of the moisture absorption and dehumidification medium layer 421, and the fourth plate body 4252 abuts against the edge of the axial end face of the moisture absorption and dehumidification medium layer 421 facing the second shell 412.

[0239] The first plate 4231 and the third plate 4251 are stacked in the radial direction, or in other words, the first plate 4231 and the third plate 4251 are in a mutually nested relationship, and the third plate 4251 can be nested in the first plate 4231, or the first plate 4231 can be nested in the third plate 4251. Figure 18 and Figure 19As shown, the two circumferential surfaces of the third plate body 4251 and the first plate body 4231 close to each other are fixedly connected through the buckling structure 426. For example, one of the two circumferential surfaces of the third plate body 4251 and the first plate body 4231 close to each other is provided with a buckling protrusion 4262, and the other is provided with a buckling groove 4261. Through the cooperation of the buckling protrusion 4262 and the buckling groove 4261, the quick connection of the first fixed ring 423 and the second fixed support 425 is realized, and the radial area occupied is not too large, which is beneficial to reduce the outer diameter of the moisture absorption and exhaust element 42.

[0240] In one embodiment, any one of the support portion 424, the fixed ring 423 and the second fixed support 425 can be made of a metal material, such as a metal stamping part, or a non-metal material, such as an injection molding part. The shaft part 427 can be made of a non-metal material to facilitate the formation of the protruding part 4275 and reduce the weight, of course, the shaft part 427 can also be made of a metal material when allowed.

[0241] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
