[0085] In order to illustrate the technical solutions described in the present application, the following will be described in detail in combination with specific drawings and embodiments.

[0086] Please refer to Figures 1 to 4 The embodiment of the present application provides a clothes processing apparatus 200.

[0087] Based on the normal working state of the clothes processing apparatus 200, for the purpose of description and understanding, here, "up", "down", "left", "right", "front", "back" and other directions are defined first, the side of the clothes processing apparatus 200 facing the user is "front", the side away from the user is "back", the side facing the ground is "down", the side 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".

[0088] As Figures 1 to 4As shown, the clothes treatment device 200 includes a device housing 1, and a drying module 100, a first driving member 5 and a drum 2 arranged in the device housing 1. The first driving member 5 is connected with the drum 2 and used to drive the drum 2 to rotate.

[0089] As shown in Figure 2 , Figure 3 and Figure 4 , the device housing 1 can include a plurality of outer standing plates 15 which are connected with each other to enclose the drying module 100. For example, the plurality of outer standing plates 15 of the device housing 1 can include 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 rear side plate, etc. In other embodiments, the plurality of outer standing plates 15 can be connected in other numbers and in other orientations.

[0090] As shown in 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 a space between the air inlet 21 and the air outlet 23 serves as a clothes treatment space 22.

[0091] As shown in Figure 2 and Figure 3 , the device housing 1 can further include 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 rear side plate and the drum 2. The drum 2 is rotatably mounted between the first support member 16 and the second support member at both axial ends of the drum 2. In some embodiments, the second support member can be integrally arranged with the rear side plate.

[0092] 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.

[0093] As shown in Figure 5 and Figure 6 , the drying module 100 can include a base assembly 11 which is located below the drum 2. The plurality of outer standing plates 15 are connected with the periphery of the base assembly 11 to enclose the drum 2.

[0094] As shown in Figure 5 , Figure 6 and Figure 7 , in one embodiment, the drying module 100 of the clothes treatment device 200 can further include a heat pump system 3 and a moisture absorption and removal 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 and dehumidification and heating on the air flowing out of the drum 2. The moisture absorption and removal system 4 is used to perform primary moisture absorption and removal (secondary dehumidification) on the air flowing out of the drum 2.

[0095] As shown in Figure 6As shown, the heat pump system 3 comprises, sequentially connected along the flow direction of refrigerant, a compressor 31, a second heat exchanger 34, a throttling device 36 and a first heat exchanger 32.

[0096] The refrigerant can be a hydrofluorocarbon (HFCs), a chlorofluorocarbon (CFCs), a hydrochlorofluorocarbon (HCFCs), or a natural refrigerant (such as ammonia, carbon dioxide, hydrocarbon, etc.). The second heat exchanger 34 serves as a heat source to heat the air so that the high-temperature air enters the drum 2, and the first heat exchanger 32 serves as a cold source to cool and condense the air flowing out of the drum 2.

[0097] In one embodiment, as shown in Figure 6 and Figure 7 The base assembly 11 defines a main drying air duct 110 therein, and further defines a receiving cavity 112 in the base assembly 11 which is isolated from the main drying air duct 110. The air inlet end of the main drying air duct 110 is in communication with the air outlet 23 of the drum 2, and the air outlet end of the main drying air duct 110 is in communication with the air inlet 21 of the drum 2. Please refer to Figure 6 and Figure 7 In the heat pump system 3, the first heat exchanger 32 and the second heat exchanger 34 are arranged along the air flow direction in the main drying air duct 110, and the compressor 31 and the throttling device 36 are arranged in the receiving cavity 112 of the base assembly 11.

[0098] In addition, as shown in Figure 5 The components not involved in the air circulation, such as the first driving member 5, are also arranged in the receiving cavity 112.

[0099] After passing through the first heat exchanger 32, the temperature of the air decreases, the absolute humidity decreases, and the relative humidity increases. After passing through the second heat exchanger 34, the temperature of the air increases, and the relative humidity decreases.

[0100] In one embodiment, the first heat exchanger 32 comprises a first evaporator, and the second heat exchanger 34 comprises a condenser.

[0101] Absolute humidity: refers to the mass of water vapor contained in a unit volume of air, which directly reflects the actual content of water vapor in the air.

[0102] Relative humidity: refers to the percentage of the actual content of water vapor (absolute humidity) in the air to the saturated water vapor content at the same temperature, which is a relative concept used to describe the degree of saturation of water vapor in the air.

[0103] When the absolute humidity remains unchanged, the decrease in temperature will increase the relative humidity, and even possibly reach the saturated state of water vapor to produce condensation. When the absolute humidity remains unchanged, the increase in temperature will decrease the relative humidity, and increase the unsaturated degree of water vapor in the air.

[0104] Therefore, the air, after passing through the second heat exchanger 34, becomes high-temperature and low-humidity (low absolute humidity, low relative humidity), and can effectively take away the moisture in the clothes after re-entering the drum 2.

[0105] The moisture absorption and removal system 4 is used to absorb and remove the moisture from the air flowing out of the drum 2 (secondary dehumidification). The moisture absorption and removal system 4 is at least partially arranged in the main drying air duct 110 and located between the first heat exchanger 32 and the second heat exchanger 34, and is used to absorb and remove the moisture from the low-temperature air after the first heat exchanger 32, so as to further reduce the absolute humidity and the relative humidity of the air.

[0106] Please refer to Figure 16 Fig. 2 shows that, in some embodiments, the moisture absorption and removal system 4 at least includes a moisture absorption and removal component 42, a moisture absorption and removal shell 41, and a regeneration assembly 44, wherein the moisture absorption and removal component 42 is arranged in the moisture absorption and removal shell 41 and functions to absorb and remove the moisture.

[0107] Please refer to Figure 22 Fig. 2 shows that the space in the moisture absorption and removal shell 41 is divided into a moisture absorption zone 4102 and a desorption zone 4101. Please refer to Figure 16 Fig. 2 shows that the moisture absorption and removal component 42 includes a moisture absorption part 4201 located in the moisture absorption zone 4102 and a desorption part 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, so as to provide the desorption energy (heat) for the moisture in the desorption part 4202.

[0108] In some embodiments, the shape of the moisture absorption and removal shell 41 can be designed according to the actual working condition requirements, as long as it at least includes the two functional zones of the moisture absorption zone 4102 and the desorption zone 4101, and the shape of each functional zone can also be designed according to the actual needs, which can be square, triangular, circular, or sector, as long as the moisture absorption zone 4102 and the desorption zone 4101 are isolated from each other. In some embodiments, the sector-shaped moisture absorption zone 4102 and the desorption zone 4101 can more effectively and reasonably utilize the space.

[0109] In some embodiments, the moisture absorption and removal component 42 is arranged in the moisture absorption and removal shell 41, as long as it can function to absorb and remove the moisture. The shape of the moisture absorption and removal component 42 is not limited, which can be polygonal such as triangular or square, or can be disc-shaped, such as Figure 16 and Figure 18As shown, the wheel-shaped moisture absorbing and removing member 42 is designed to move cyclically between the moisture absorbing zone 4102 and the desorption zone 4101. The part of the moisture absorbing and removing member 42 (i.e. the moisture absorbing part 4201) moving to the moisture absorbing zone 4102 absorbs moisture in the air, and then the part of the moisture absorbing and removing member 42 (i.e. the desorption part 4202) moving to the desorption zone 4101 desorbs the absorbed moisture. The part of the moisture absorbing and removing member 42 after desorption moves to the moisture absorbing zone 4102 again to absorb moisture, and the process is repeated to remove moisture in the air, thereby achieving the effect of moisture absorption and removal.

[0110] In some embodiments, the moisture absorbing and removing member 42 is a dehumidification rotating disc member. The dehumidification rotating disc in the dehumidification rotating disc member can be a honeycomb or corrugated rotating disc carrying a moisture absorbent, which can adsorb and desorb the absorbed water vapor to achieve repeated desorption and regeneration. In some embodiments, the dehumidification rotating disc includes inorganic / organic fiber carriers such as ceramic, glass fiber, MOFs (Metal-Organic Frameworks), COFs (Covalent-Organic Frameworks), cordierite, etc., and the fiber carriers are coated with a moisture absorbent such as a molecular sieve, which is uniformly distributed between the fiber carriers and on the surface of the fiber carriers to achieve adsorption of moisture in the air flow. The moisture absorbent can be, for example, a zeolite, a modified / synthetic zeolite, a molecular sieve (including but not limited to single-crystal molecular sieves such as A-type molecular sieves, X / Y-type molecular sieves, ZSM molecular sieves, Beta molecular sieves, etc., or mixed-crystal molecular sieves, etc.), a high-molecular-weight moisture absorbent, an alkali metal aluminosilicate (13X molecular sieve), lithium chloride, silica gel, modified silica gel, activated alumina, etc.

[0111] In an optional embodiment, the moisture absorbing and removing member 42 is a molecular sieve dehumidification rotating disc.

[0112] In an embodiment, the regeneration assembly 44 is a heating member for heating the air in the desorption zone 4101. In an embodiment, the regeneration assembly 44 includes an electric heating member.

[0113] Then, please refer to Figure 6 , Figure 7 and Figure 8 As shown, in an embodiment, the heat pump system 3 further includes a third heat exchanger 33 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 and condensing the high-temperature air after the desorption part 4202 to remove moisture, thereby reducing the absolute humidity of the air after the desorption part 4202.

[0114] By using the third heat exchanger 33 as the cold source of the moisture adsorption and removal system 4, the heat internal circulation in the regeneration process of the moisture adsorption and removal system 4 can be further realized, and the high-temperature air is prevented from being discharged outside the equipment shell 1. The laundry treatment device 200 has a wider applicability.

[0115] In one embodiment, the third heat exchanger 33 comprises a second evaporator.

[0116] 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, as shown in 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 of refrigerant outflow.

[0117] In other alternative 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 can be connected in sequence along the direction of refrigerant outflow. In other alternative embodiments, based on the design of the base assembly 11 or other design requirements, the third heat exchanger 33 can be connected in parallel with the first heat exchanger 32 downstream of the throttling device 36; or the throttling device 36 comprises two throttling devices connected in parallel, one of which is connected in series with the first heat exchanger 32, and the other of which is connected in series with the third heat exchanger 33, and the first heat exchanger 32 and the third heat exchanger 33 are connected in parallel.

[0118] Please refer to Figure 6 , the base assembly 11 is further provided with a regeneration air duct, which is at least composed of the desorption area 4101 in the moisture adsorption and removal shell 41 and the first air duct part 1111, and is used for accommodating the desorption part 4202 of the moisture adsorption and removal member 42 and the third heat exchanger 33. The regeneration air duct and the main drying air duct 110 are functionally independent and structurally isolated.

[0119] Next, the base assembly 11 and the arrangement of the heat pump system 3 on the base assembly 11 will be described in detail.

[0120] Please refer to Figure 5 , Figure 6 , Figure 11 and Figure 12 , the base assembly 11 comprises a base 12 and an upper cover 13, as shown in Figure 5 and Figure 6As shown, the base 12 comprises a bottom plate 120 and a first side plate 121 arranged on the upper surface of the bottom plate 120, and the upper cover 13 is connected with the end surface of the first side plate 121 away from the bottom plate 120, i.e., the upper end surface of the first side plate 121, to define the main drying air duct 110.

[0121] In an optional embodiment, as shown in Figure 7 and Figure 16 , at least a part of the moisture absorption and removal shell 41 and the moisture absorption and removal member 42 are arranged in the main drying air duct 110, and the rotation center axis of the moisture absorption and removal member 42 is parallel to the air direction in the main drying air duct 110. It can be understood that here, the rotation center axis of the moisture absorption and removal member 42 is not parallel to the air direction at any position in the main drying air duct 110, but is parallel to the air direction in the part of the main drying air duct 110 where the moisture absorption and removal member 42 is arranged. That is, the air passing through the moisture absorption and removal member 42 flows straight in the main drying air duct 110.

[0122] The purpose of such arrangement is to make the air flow straight in the part of the main drying air duct 110 where the moisture absorption and removal member 42 is arranged, reducing the possibility of air reversing and vortex, so that the drying module 100 has high air passing efficiency and small air resistance, and the main drying air duct 110 and the moisture absorption and removal system 4 do not need complex isolation and sealing structure, and the clothes treatment apparatus 200 has the advantages of fast drying speed and low energy consumption.

[0123] Please refer to Figure 5 and Figure 6 , in an embodiment, the base 12 further comprises a second side plate 122 arranged on the upper surface of the bottom plate 120 and located beside the first side plate 121. The upper cover 13 is further connected with the upper end surface of the second side plate 122 to define the first air duct part 1111 of the regeneration air duct.

[0124] In an embodiment, the second air duct part is arranged in the moisture absorption and removal shell 41 arranged in the main drying air duct 110. The first air duct part 1111 and the second air duct part are in communication and constitute the regeneration air duct. The second heat exchanger 34 is arranged in the first air duct part 1111.

[0125] It can be understood that, as far as the base assembly 11 is concerned, the part of the main drying air duct 110 for accommodating the moisture absorption and removal shell 41 does not necessarily need to be divided by a clear dividing structure, but the other part of the regeneration air duct, i.e., the desorption area 4101, is defined by the internal part of the moisture absorption and removal shell 41 arranged in the main drying air duct 110.

[0126] The first heat exchanger 32 and the second heat exchanger 34 are arranged in the main drying air duct 110, i.e., at the upper surface of the bottom plate 120, and the first heat exchanger 32 generates condensed water around it. Therefore, in an embodiment, please refer to Figure 11 andFigure 12 As shown in Figs. 1, 2 and 3, the bottom plate 120 is provided with a water running channel 113 within the main drying air duct 110, or in other words, the condensed water will drop onto the upper surface of the bottom plate 120, and the space below the main drying air duct 110 can serve as the water running channel 113.

[0127] As shown in Figs. 1, 2 and 3, the bottom plate 120 is provided with a water running channel 113 within the main drying air duct 110, or in other words, the condensed water will drop onto the upper surface of the bottom plate 120, and the space below the main drying air duct 110 can serve as the water running channel 113.

Figure 11 As shown in Figs. 1, 2 and 3, the bottom plate 120 is provided with a water running channel 113 within the main drying air duct 110, or in other words, the condensed water will drop onto the upper surface of the bottom plate 120, and the space below the main drying air duct 110 can serve as the water running channel 113.

[0128] The water collecting box 123 can be provided as a drawer type, a screw type or other detachable water collecting structure, or can be drained into the sewer through a water pipe.

[0129] As shown in Figs. 1, 2 and 3, the bottom plate 120 is provided with a water running channel 113 within the main drying air duct 110, or in other words, the condensed water will drop onto the upper surface of the bottom plate 120, and the space below the main drying air duct 110 can serve as the water running channel 113.

[0130] As shown in Figs. 1, 2 and 3, the bottom plate 120 is provided with a water running channel 113 within the main drying air duct 110, or in other words, the condensed water will drop onto the upper surface of the bottom plate 120, and the space below the main drying air duct 110 can serve as the water running channel 113.

[0131] As shown in Figs. 1, 2 and 3, the bottom plate 120 is provided with a water running channel 113 within the main drying air duct 110, or in other words, the condensed water will drop onto the upper surface of the bottom plate 120, and the space below the main drying air duct 110 can serve as the water running channel 113.​​​​Figure 6 , Figure 11 and Figure 12 As shown, in one embodiment, a plurality of raising blocks 124 protrude from the upper surface of the base plate 120. The raising blocks 124 are used to support the partition plate 14 at a certain height, that is, the partition plate 14 is located on the end face of the raising block 124 facing the upper cover 13. In order to evenly support the multiple positions of the partition plate 14, the raising blocks 124 are designed with different shapes and positions. For example, referring to… Figure 6 As shown, a portion of the raised blocks 124 (first raised blocks 1241) are disposed on the inner peripheral wall of the first side plate 121 to support the edge of the isolation plate 14, and another portion of the raised blocks 124 (multiple second raised blocks 1242) are disposed at intervals in the water channel 113 and the main drying air duct 110 to provide multi-point support for the middle part of the isolation plate 14.

[0132] like Figure 11 and Figure 12 As shown, in one embodiment, a portion of the raised blocks 124 (the third raised block 1243) surround and define a first mounting cavity 1240 within the water channel 113. The first mounting cavity 1240 is configured to accommodate a part of the moisture absorption and desiccation system 4, specifically, a part of the moisture absorption and desiccation housing 41. The isolation plate 14 has a clearance opening 143 corresponding to the first mounting cavity 1240. Figure 11 As shown. Thus, the moisture absorption and dehumidification system 4 can be located partly above the partition plate 14 and partly below the partition plate 14, and is 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 as possible to the bottom plate 120 in the vertical direction, thereby lowering the position of the moisture absorption and dehumidification system 4 and consequently reducing the overall height of the garment processing equipment 200.

[0133] In one optional embodiment, where permissible, the lower surface of the base plate 120 may protrude downwards corresponding to the first mounting cavity 1240, and the upper surface of the base plate 120 may be recessed downwards corresponding to the first mounting cavity 1240, such as... Figure 6 and Figure 11 As shown, the position of the moisture absorption and dehumidification system 4 is further reduced.

[0134] Please see Figure 6 As shown, the upper surface of the isolation plate 14 corresponding to the first heat exchanger 32 is designed as a downward concave surface, and at least part of the water leakage hole 141 is provided on the concave surface. The purpose of this design is to better guide the water dripping from the first heat exchanger 32 to the water leakage hole 141, and then through the water leakage hole 141 to the water channel 113 below the isolation plate 14.

[0135] Furthermore, condensate will also be generated around the first heat exchanger 32. Therefore, in one embodiment, please refer to...Figure 6 and Figure 12 As shown, the upper surface of the isolation plate 14 is provided with a water-blocking strip 142. The water-blocking strip 142 is located on the side of the first heat exchanger 32 near the moisture absorption and dehumidification system 4, and is spaced a certain distance from the first heat exchanger 32. Drainage holes 141 and clearance openings 143 are located on opposite sides of the water-blocking strip 142. The purpose of this arrangement is that, since the airflow direction is from the first heat exchanger 32 to the moisture absorption and dehumidification system 4, significant condensation will also occur in the space downstream of the first heat exchanger 32. The water-blocking strip 142 can block this condensation outside the clearance opening 143, preventing condensation from entering the clearance opening 143 and the first mounting cavity 1240. Based on the height relationship between the concave surface and the water-blocking strip 142, one or more drainage holes 141 can be provided on the side of the water-blocking strip 142 near the first heat exchanger 32, such as... Figure 13 As shown.

[0136] Please see Figure 6 and Figure 6 As shown, in one embodiment, a downwardly extending baffle 144 is formed on the partition plate 14 around the periphery of the clearance opening 143. The baffle 144 may be a closed enclosure. Therefore, the baffle 144 is located within the first mounting cavity 1240. The purpose of this arrangement is that, when assembling the moisture absorption and dehumidification system 4, the baffle 144 can guide the moisture absorption and dehumidification system 4. In addition, the interference fit between the baffle 144 and the first pad can further prevent condensate in the water channel 113 from entering the first mounting cavity 1240.

[0137] In one embodiment, the isolation plate 14 may be fixedly connected to at least one shim block 124 by fasteners, for example, to a third shim block 1243 by fasteners. The fasteners may be bolts, screws, or other structures that can be fixed.

[0138] In one embodiment, at least one shim 124 is connected to the lower surface of the partition plate 14 via a limiting fit structure. For example, at least the upper surface of the first shim 1241 is provided with a limiting structure (not shown), and the lower surface of the partition plate 14 is provided with a matching fit structure (not shown) corresponding to the limiting structure. The limiting structure can be a groove or a protrusion, and the fit structure can be a protrusion or a groove. Through the interlocking fit between the upper surface of the first shim 1241 and the lower surface of the partition plate 14, the installation stability of the partition plate 14 on the shim 124 can be further ensured.

[0139] In other embodiments, other shims 124 may also be connected to the isolation plate 14 via fasteners and / or limiting fit structures. For example, the third shim 1243 may be connected to the isolation plate 14 via fasteners, and the second shim 1242 may be connected to the isolation plate 14 via a limiting fit structure.

[0140] As shown in Figure 7 In one embodiment, the upper end faces of the first side plate 121 and the second side plate 122 are connected together with the lower end face of the upper cover 13 through a sealing structure 131. The sealing structure 131 includes a sealing protrusion 1311 and a sealing groove 1312. For example, the upper end faces of the first side plate 121 and the second side plate 122 are provided with one of the sealing protrusion 1311 and the sealing groove 1312, and the lower end face of the upper cover 13 is provided with the other one of the sealing protrusion 1311 and the sealing groove 1312, and the sealing protrusion 1311 is located in the sealing groove 1312. In an alternative embodiment, a sealing member (not shown), such as an elastic sealing strip, is arranged between the sealing protrusion 1311 and the sealing groove 1312. In addition, the first side plate 121, the second side plate 122 and the upper cover 13 are fastened together through fasteners (such as screws or bolts) to keep the sealing member pressed between the sealing protrusion 1311 and the sealing groove 1312, thereby ensuring the sealing between the first side plate 121, the second side plate 122 and the upper cover 13.

[0141] As shown in Figure 4 The second side plate 122 is connected with a part of the first side plate 121, or in other words, a part of the first side plate 121 is used to define the first air duct part 1111 together with the second side plate 122. As shown in Figure 8 and Figure 9 The first side plate 121 is provided with a first communication port 1211 and a second communication port 1212, the first communication port 1211 communicates the main drying air duct 110 and the first air duct part 1111, and the second side plate 122 is provided with a third communication port 1221, the second communication port 1212 and the third communication port 1221 both communicate with the accommodating cavity 112. The first communication port 1211 is used to form communication between the first heat exchanger 32 and the desorption area 4101 of the moisture absorption and removal shell 41 along the air direction, and the second communication port 1212 and the third communication port 1221 are used to form communication between the first heat exchanger 32 and the regeneration assembly 44 along the air direction.

Generally, based on the positional relationship between the tensioning member and the synchronous wheel, the tensioning member is arranged to be inclined relative to the vertical direction and the horizontal direction, and the chamfered cambered surface 1270 is used to avoid the tensioning member, so as to avoid the interference caused by the elastic expansion of the tensioning member to the right angle chamfered surface.

[0145] The rear side of the base 12 is used to be connected with the rear side plate. As shown in Figure 11 , 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, and the side of the guide block 126 facing the first side plate 121 has a guide surface 1260, which is inclined to the first side plate 121 in the direction from the upper cover 13 to the bottom plate 120. In this way, when the rear side plate is installed, 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 surface 1260 and enters the front side of the guide block 126, thereby realizing the rapid positioning and pre-fixing connection between the rear side plate and the base 12.

[0146] Please refer to Figure 11 , Figure 2 and Figure 3 , in one embodiment, the base 12 further includes a third side plate 125 provided on the bottom plate 120 and located outside the first side plate 121 and the second side plate 122, the third side plate 125 defines a front air duct 1250; as shown in Figure 2 , the third side plate 125 is provided with a fourth communication port 1251 connected with the main drying air duct 110, and the end surface of the third side plate 125 away from the bottom plate 120 defines a fifth communication port 1252, the second communication port 1212 is used to communicate with the air outlet 23 of the drum 2.

[0147] In one embodiment, please refer to Figure 3 and Figure 2As shown, the first support member 16 is provided with a third opening 161 corresponding to the air inlet 21 of the drum 2. The third opening 161 is in communication with the air inlet 21 in the axial direction of the drum 2. During rotation of the drum 2, the air inlet 21 is always in communication with the third opening 161. The third opening 161 is also in communication with the front air duct 1250, so that the laundry treatment space 22 of the drum 2 is in communication with the front air duct 1250.

[0148] Specifically, please refer to Figure 3 and Figure 6 As shown, the first support member 16 is provided with a third opening 161 corresponding to the air inlet 21 of the drum 2. The third opening 161 is in communication with the air inlet 21 in the axial direction of the drum 2. During rotation of the drum 2, the air inlet 21 is always in communication with the third opening 161. The third opening 161 is also in communication with the front air duct 1250, so that the laundry treatment space 22 of the drum 2 is in communication with the front air duct 1250.

[0149] Please refer to Figure 12 and Figure 16 As shown, the first support member 16 is provided above the third side plate 125. The filter air duct 160 and the front air duct 1250 are generally aligned in the up-down direction.

[0150] Please refer to Figure 17 and Figure 6 As shown, in one embodiment, the upper cover 13 is provided with a first wire passing hole 132. The first wire passing hole 132 is used for power supply wires, signal wires, etc. to pass through. In some embodiments, the regenerating assembly 44 includes a heating element 441. Please refer to Figure 12 and Figure 4 As shown, the heating element 441 is specifically an electric heating element, at this time, the power supply wires are used to provide electric energy for the electric heating element.

[0151] As shown in Figure 4 and Figure 6 The edge of the upper cover 13 is provided with a plurality of spaced-apart wire fixing blocks 133. The wire fixing blocks 133 are used to provide fixing action for power supply wires, signal wires, etc. passing out of the first wire passing hole 132. The form of the wire fixing blocks 133 is not limited.

[0152] Please refer to Figure 12 As shown, in one embodiment, the laundry treatment apparatus 200 further includes a main circulating fan 6, the main circulating fan 6 is at least partially arranged in the main drying air duct 110, the first driving member 5 is connected with the main circulating fan 6 to drive the main circulating fan 6 to rotate, and the main circulating fan 6 is used to drive air in the main drying air duct 110 to flow.

[0153] In one embodiment, asFigure 6 As shown, the main circulating fan 6 is arranged downstream of the second heat exchanger 34, for conveying air in the main drying air duct 110 to the air inlet 21 of the drum 2.

[0154] In one embodiment, the first driving member 5 is a double driving member, such as a double rotor motor, having a first driving shaft and a second driving shaft (not shown), the second driving shaft being used to drive the drum 2, and the first driving shaft being used to connect with the main circulating fan 6. In this way, one first driving member 5 can be used to provide the operation of the drum 2 and the main circulating fan 6, thereby saving structural cost and reducing volume occupation.

[0155] Please refer to Figure 7 and Figure 10 As shown, the main circulating fan 6 is arranged between the upper cover 13 and the first side plate 121, and the upper cover 13 and / or the first side plate 121 is provided with a mounting position 135 for mounting the main circulating fan 6. For example, the mounting position 135 can be a mounting hole defined by the upper cover 13 and / or the first side plate 121. In order to adapt to the shape of the main circulating fan 6, and to reduce the height of the base assembly 11 as much as possible at least corresponding to the position of the main circulating fan 6, in one embodiment, the upper surface of the upper cover 13 corresponding to the main circulating fan 6 is provided with one or more reinforcing ribs 134, so as to thin the design of the upper cover 13 as much as possible while ensuring the strength of the upper cover 13.

[0156] In one embodiment, any one of the base 12, the isolation plate 14 and the upper cover 13 can be a plastic member, for example, an integral structure formed by injection molding. In addition, the plastic base 12, the isolation plate 14 and the upper cover 13 also have a lower thermal conductivity, which has a lower heat exchange between the air in the main drying air duct 110 and the air in the regeneration air duct.

[0157] Next, please refer to Figure 10 , Figure 6 and Figure 8 As shown, in the heat pump system 3, the compressor 31, the second heat exchanger 34, the throttling device, the third heat exchanger 33 and the first heat exchanger 32 are sequentially communicated through the refrigerant pipe 35.

[0158] During the operation of the compressor 31, the suction and discharge of the refrigerant are constantly occurring, and therefore the compressor 31 will generate vibration. Generally, the vibration is mostly multi-directional vibration in the horizontal plane. In order to reduce the pulling and extrusion of the refrigerant pipe 35 during the vibration of the compressor 31, and to avoid the refrigerant pipe 35 from being broken, especially the part of the refrigerant pipe 35 close to the compressor 31, such as Figure 10As shown, in one embodiment, the refrigerant pipe 35 comprises a plurality of pipe segments 351, adjacent pipe segments 351 are connected in a relative bending manner in a horizontal direction and / or a vertical direction. For example, when the compressor 31 vibrates along the left-right direction, and the first pipe segment 351 connected with the compressor 31 also extends along the left-right direction, the first pipe segment 351 will generate a moving amount along the left-right direction, and the second pipe segment 351 will generate a deflection or bending towards the left-right direction. For the pipe segments 351 connected in sequence and elongated (length is greater than outer diameter), the deflection or bending will obviously reduce the risk of breakage compared to the pulling and extrusion along the length direction. When the plurality of pipe segments 351 are connected in sequence in a bending manner, the pulling and extrusion of the refrigerant pipe 35 caused by the vibration of the compressor 31 will be obviously improved.

[0159] The adjacent pipe segments 351 are connected in a relative bending manner in a horizontal direction, which means that the projections of the adjacent pipe segments 351 on a horizontal plane or on the bottom plate 120 are connected in a bending manner; the adjacent pipe segments 351 are connected in a relative bending manner in a vertical direction, which means that the projections of the adjacent pipe segments 351 in a vertical plane are connected in a bending manner.

[0160] In one embodiment, the refrigerant pipe 35 is a copper pipe. The copper pipe has good ductility, which is convenient for manufacturing the plurality of pipe segments 351 connected in a relative bending manner. Further optionally, the adjacent pipe segments 351 are connected in a smooth transition manner, so as to reduce the resistance of the refrigerant flowing between the pipe segments 351, and facilitate the assembly operation of the clothes treatment apparatus 200, etc.

[0161] As shown in FIG. 1, Figure 15 and Figure 16 As shown, in one embodiment, the shell of the compressor 31 is provided with a plurality of first fixing ears 311, each first fixing ear 311 is provided with a fixing hole 3110, the first fastener 37 is arranged in the fixing hole 3110 and connected with the bottom plate 120, and the outer diameter of the first fastener 37 is smaller than the inner diameter of the fixing hole 3110. In this way, an annular gap is formed around the first fastener 37. The purpose of this arrangement is to adapt to the vibration of the compressor 31 as mentioned above. If the first fixing ear 311 is fixedly connected with the first fastener 37 without a gap, in the process of continuous vibration of the compressor 31, the first fixing ear 311 of the compressor 31 may be damaged, and even the shell of the compressor 31 may be damaged, and the vibration of the bottom plate 120 and the entire base 12 and the base assembly 11 may be caused. In the embodiment of the present application, the vibration of the compressor 31 is transmitted to the refrigerant pipe 35, and is buffered and consumed by the pipe segments 351 connected in a bending manner, which reduces the damage to the compressor 31 itself, and also reduces the vibration of the entire clothes treatment apparatus 200.

[0162] In one optional embodiment, please refer to Figure 17As shown, in the heat pump system 3, a plurality of sequentially connected pipe sections 351 define an avoiding space 350 for accommodating the first driving member 5. The purpose of such arrangement is that the refrigerant pipe 35 and the first driving member 5 are both arranged in the accommodating cavity 112 of the bottom plate 120, and the refrigerant pipe 35 needs to avoid the first driving member 5, and optionally, at least a portion of the refrigerant pipe 35 is located below the first driving member 5 so as not to affect the connection between the first driving member 5 and the drum 2. Therefore, the portion of the pipe section 351 located below the first driving member 5 and the portion of the pipe section 351 located around the first driving member 5 are arranged to adapt to the shape of the first driving member 5, thereby defining the above-mentioned avoiding space 350.

[0163] Next, the moisture absorption and removal system 4 of the embodiment will be introduced.

[0164] As shown in Figure 22 、 Figure 14 、 Figure 16 and Figure 22 , in one embodiment, in the moisture absorption and removal system 4, the moisture absorption and removal shell 41 is provided with a first opening 4110, as shown in Figure 14 、 Figure 16 and Figure 22 , the moisture absorption and removal shell 41 is further provided with a second opening 4120, and the first opening 4110 and the second opening 4120 respectively expose a portion of the surface of the moisture absorption and removal member 42, so that the first opening 4110 and the second opening 4120 are in communication through the moisture absorption part 4201 of the moisture absorption and removal member 42, and the air passes through the passageway formed by the first opening 4110, the moisture absorption part 4201 and the second opening 4120 in sequence, and the moisture therein can be absorbed by the moisture absorption part 4201. The portion of the moisture absorption and removal shell 41 corresponding to the portion between the first opening 4110 and the second opening 4120 is the said moisture absorption area 4102.

[0165] In an optional embodiment, as shown in Figure 15 、 Figure 16 and Figure 17 , the first opening 4110 is formed on the first axial end surface of the moisture absorption and removal shell 41, and the first opening 4110 exposes a portion of the first axial end surface of the moisture absorption and removal member 42. In this way, the first opening 4110 can be made in a simple form and has a larger area, which facilitates increasing the air passing area of the moisture absorption part 4201 and improving the absorption efficiency of the moisture in the moisture absorption part 4201.

[0166] In an optional embodiment, as shown in Figure 22 、 Figure 16 、 Figure 21 and Figure 22As shown, the second opening 4120 is formed on the second axial end surface of the moisture absorbing and releasing shell 41, and exposes a portion of the second axial end surface of the moisture absorbing and releasing member 42. Similarly, this allows the second opening 4120 to be made in a simple form and have a larger area, facilitating an increase in the air passing area of the moisture absorbing portion 4201 and an improvement in the moisture adsorption efficiency in the moisture absorbing portion 4201.

[0167] In an alternative embodiment, as shown in Figure 16 , Figure 17 and Figure 22 , the first opening 4110 is formed on the first axial end surface of the moisture absorbing and releasing shell 41, and the second opening 4120 is formed on the second axial end surface of the moisture absorbing and releasing shell 41. Overall, the moisture absorbing and releasing shell 41 and the moisture absorbing and releasing member 42 have a larger air passing area, which is conducive to improving the moisture adsorption efficiency, reducing the consumption of air kinetic energy, reducing energy consumption, and improving drying efficiency.

[0168] Further alternatively, as shown in Figure 7 , Figure 7 and Figure 16 , the first opening 4110 and the second opening 4120 communicate with each other along the axial direction through the moisture absorbing portion 4201 of the moisture absorbing and releasing member 42. In this way, the first opening 4110 and the second opening 4120 are aligned and communicated along the axial direction of the moisture absorbing and releasing member 42. The air passes through the moisture absorbing and releasing member 42 along the axial direction, which has a larger air passing area and adsorption area, and has a smaller air resistance, which is conducive to improving the flow speed of the air in the moisture absorbing and releasing system 4, thereby improving the moisture desorption efficiency and reducing energy consumption.

[0169] In an embodiment, the first axial end surface and the second axial end surface of the moisture absorbing and releasing member 42 are circular. The first opening 4110 and the second opening 4120 are both fan-shaped. Alternatively, the area of the first opening 4110 and the second opening 4120 is more than 50% of the area of the axial end surface of the moisture absorbing and releasing member 42. Further alternatively, the area of the first opening 4110 and the second opening 4120 is more than 60% of the area of the axial end surface of the moisture absorbing and releasing member 42. Further alternatively, the area of the first opening 4110 and the second opening 4120 is more than 70% of the area of the axial end surface of the moisture absorbing and releasing member 42. Further alternatively, the area of the first opening 4110 and the second opening 4120 is more than 80% of the area of the axial end surface of the moisture absorbing and releasing member 42. In this way, it is ensured that the first opening 4110 and the second opening 4120 both have sufficient area, and at the same time, the moisture absorbing and releasing member 42 allows a smaller diameter and volume to be designed, which is conducive to reducing the overall volume of the moisture absorbing and releasing system 4 and the overall volume of the clothes treatment apparatus 200.

[0170] Please refer to Figure 17As shown, in one embodiment, the first heat exchanger 32, the moisture absorption and removal system 4 and the second heat exchanger 34 are arranged in the main drying air duct 110 along the axial direction of the moisture absorption and removal member 42 in sequence. Figure 21 As shown, in one embodiment, the first heat exchanger 32, the moisture absorption and removal system 4 and the second heat exchanger 34 are arranged in the main drying air duct 110 along the axial direction of the moisture absorption and removal member 42 in sequence,

[0171] As shown in Figure 22 , Figure 16 , Figure 17 and Figure 22 , the moisture absorption and removal shell 41 includes a first shell 411 and a second shell 412, which are connected opposite to each other on both sides of the axial direction of the moisture absorption and removal member 42 to confine the moisture absorption and removal member 42. The first opening 4110 is arranged on the first shell 411, and the second opening 4120 is arranged 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, as shown in Figure 22 and Figure 14 , in one optional embodiment, according to the shape of the first shell 411 and the second shell 412, at positions where it is inconvenient to arrange 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.

[0172] As shown in Figure 16 , 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 connected along the axial direction of the moisture absorption and removal member 42 to form a second air duct part, that is, a desorption area 4101 of the moisture absorption and removal shell 41. In this way, the moisture absorption and removal shell 41 is arranged at least partially in the main drying air duct 110, and the second air duct part in the moisture absorption and removal shell 41 is connected in communication with the first air duct part 1111 outside the main drying air duct 110, thereby forming a regeneration air duct.

[0173] Please refer to Figure 22 As shown in FIG. 11, the first casing 411 is provided with an air outlet air duct part 4115, and the second casing 412 is provided with an air inlet air duct part 4125. The air inlet air duct part 4125 and the air outlet air duct part 4115 are connected via the desorption part 4202 of the moisture absorption and removal component 42, and form the second air duct part described above. That is, in the regeneration air duct, the air in the second casing 412 passes through the desorption part 4202, enters the first casing 411, reaches the third heat exchanger 33, and finally circulates back to the second casing 412.

[0174] The first opening 4110 is used for air inlet, and the second opening 4120 is used for air outlet. In this embodiment, the air flow direction 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.

[0175] In other alternative embodiments, the air outlet air duct part 4115 can also be formed on the second casing 412, and the air inlet air duct part 4125 is formed on the first casing 411, so that the air flow direction in the desorption part 4202 is the same as the flow direction in the moisture absorption part 4201; or, the first opening 4110 is used for air outlet, and the second opening 4120 is used for air inlet, so that the air flow direction in the desorption part 4202 is the same as the flow direction in the moisture absorption part 4201.

[0176] Please refer to Figure 22 , Figure 15 and Figure 16 As shown in FIG. 11, in one embodiment, the first casing 411 is provided with a first outer air guide surface 4114, which is inclined to the axial direction of the moisture absorption and removal component 42, specifically, gradually inclined to the desorption part 4202 in the direction towards the central axis of the moisture absorption and removal component 42.

[0177] The first outer air guide surface 4114 is used to guide the air in the main drying air duct 110, so that the air is gradually concentrated into the first opening 4110 on the moisture absorption and removal casing 41, avoiding vortex when the air reaches the surface of the first casing 411. Among them, Figure 16 The solid triangle arrow in FIG. 11 indicates the direction of the air. Further, this can ensure the air flow speed in the main drying air duct 110, ensure the adsorption efficiency of the moisture in the moisture absorption part 4201, reduce the energy consumption of the clothes treatment equipment 200, and improve the drying efficiency of the clothes treatment equipment 200.

[0178] In one alternative embodiment, please refer to Figure 17 and Figure 22 As shown in FIG. 11, the width of the first outer air guide surface 4114 gradually decreases in the direction towards the central axis of the moisture absorption and removal component 42. That is, from the axial direction of the moisture absorption and removal component 42, the first outer air guide surface 4114 is fan-shaped, which corresponds to the fan-shaped shape of the first opening 4110.

[0179] Please continue reading. Figure 14 , Figure 16 and Figure 22 As shown, in one embodiment, the second housing 412 is further provided with a second external air guide surface 4124. The second external air guide surface 4124 is axially inclined to the moisture absorption and desiccation component 42, specifically, it gradually inclines towards the desorption portion 4202 in the direction towards the central axis of the moisture absorption and desiccation component 42. The purpose of this arrangement is to guide the air in the main drying air duct 110 so that after the air flows out from the second opening 4120, it flows evenly to the second heat exchanger 34, avoiding the generation of eddies between the second housing 412 and the second heat exchanger 34.

[0180] This ensures the airflow speed within the main drying duct 110, guarantees the moisture adsorption efficiency in the moisture absorption section 4201, reduces the energy consumption of the garment processing equipment 200, and improves the drying efficiency of the garment processing equipment 200.

[0181] In one alternative embodiment, please refer to Figure 16 As shown, the width of the second outer air guide surface 4124 gradually decreases in the direction toward the central axis of the moisture absorption and desiccation component 42. That is to say, viewed from the axial direction of the moisture absorption and desiccation component 42, the second outer air guide surface 4124 is fan-shaped, which corresponds to the fan-shaped shape of the second opening 4120.

[0182] Please continue reading. Figure 17 and Figure 22 As shown, in one embodiment, a first inner air guide surface 4113 is provided on the inner wall of the first housing 411. The first inner air guide surface 4113 is inclined axially to the moisture absorption and desiccation component 42, specifically, it gradually inclines towards the desorption portion 4202 in the direction towards the central axis of the moisture absorption and desiccation component 42. The first inner air guide surface 4113 is used to guide the air flowing out of the desorption portion 4202 to change direction, avoiding abrupt reversal of air flow from the desorption portion 4202 to the third heat exchanger 33, which would cause eddies and energy loss. Optionally, the first outer air guide surface 4114 is generally parallel to the first inner air guide surface 4113.

[0183] Furthermore, by setting the first inner air guide surface 4113, the airflow speed inside the moisture absorption and dehumidification system 4 is guaranteed, the desorption efficiency of moisture in the desorption section 4202 is guaranteed, the energy consumption of the clothing processing equipment 200 is reduced, and the drying efficiency of the clothing processing equipment 200 is improved.

[0184] In one alternative 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 desiccation member 42. That is, viewed from the axial direction of the moisture absorption and desiccation member 42, the first inner air guide surface 4113 is fan-shaped, which corresponds to the fan-shaped shape of the first opening 4110.

[0185] Similarly, as shown in Figure 17 , Figure 22 and Figure 16 , in an embodiment, the inner wall of the second shell 412 is provided with a second inner air guide surface 4123, which is axially inclined to the moisture absorbing and removing member 42, specifically, gradually inclined to the desorption part 4202 in the direction towards the central axis of the moisture absorbing and removing member 42. The second inner air guide surface 4123 is used to change the direction of the air flowing out of the desorption part 4202, so as to avoid vortex flow 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.

[0186] In an optional embodiment, as shown in Figure 17 , the width of the second inner air guide surface 4123 gradually decreases in the direction towards the central axis of the moisture absorbing and removing member 42. That is to say, as viewed from the axial direction of the moisture absorbing and removing member 42, the second inner air guide surface 4123 is in the shape of a sector, which corresponds to the sector shape of the second opening 4120.

[0187] In an embodiment, as shown in Figure 16 , the inner wall of the first shell 411 is provided with a first inner air guide surface 4113, and the inner wall of the second shell 412 is provided with a second inner air guide surface 4123. The first inner air guide surface 4113 and the second inner air guide surface 4123 are designed symmetrically about the radial plane of the moisture absorbing and removing member 42.

[0188] As shown in Figure 17 and Figure 17 , in an embodiment, the heating member 441 of the regeneration assembly 44 is arranged in the second shell 412, i.e. in the air inlet air duct part 4125, to heat the air entering the desorption part 4202. Specifically, the heating member 441 can be an electric heating pipe, an electric heating plate or other electric heating structural member, which is fixed on the inner wall surface of the second shell 412.

[0189] As shown in Figure 17 , the heating member 441 is fixed on the inner wall surface of the second shell 412 and is arranged in a spaced manner with the second inner air guide surface 4123. The air in the air inlet air duct part 4125 is heated by the heating member 441 after being guided by the second inner air guide surface 4123. The purpose of this arrangement is that the heating member 441 is closer to the surface of the desorption part 4202 of the moisture absorbing and removing member 42, so that heat can be more easily transferred to the moisture absorbing and removing member 42, thereby improving energy utilization and the desorption efficiency of the desorption part 4202.

[0190] Specifically as Figure 17As shown, the heating element 441 is fixed on the inner wall surface of the second housing 412 by the second fastener 413. The specific form of the second fastener 413 is not limited as long as it can be adapted 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, and for an electric heating plate, the fastener can be adapted to the plate surface.

[0191] As shown in FIG. 4A, the second housing 412 is provided with a second inner air guide surface 4123. The second inner air guide surface 4123 is arranged to be substantially parallel to the first inner air guide surface 4113. The second inner air guide surface 4123 is arranged to be substantially perpendicular to the first inner air guide surface 4113. The second inner air guide surface 4123 is arranged to be substantially parallel to the first inner air guide surface 4113. The second inner air guide surface 4123 is arranged to be substantially perpendicular to the first inner air guide surface 4113. Figure 22 As shown, in one embodiment, the heating element 441 is fixed on the inner wall surface of the second housing 412 by the mounting plate 45. Since the heating element 441 is substantially aligned with the second inner air guide surface 4123 in the axial direction, in order to keep the heating element 441 substantially parallel to the axial surface of the moisture absorbing and removing element 42 to facilitate uniform heating of the heating element 441 to the surface of the desorption part 4202, a mounting plate 45 is provided to fix the heating element 441 and keep the orientation of the heating element 441. The mounting plate 45 can be optionally in the form of a flat plate, maintaining a large contact area between the heating element 441 to ensure the stability of the installation of the heating element 441.

[0192] As shown, the mounting plate 45 is of a porous structure so as not to affect the flow of air from the second inner air guide surface 4123 to the heating element 441. Figure 14

[0193] Specifically, as shown in FIG. 4A and FIG. 4B, in one embodiment, the second inner air guide surface 4123 is provided with a mounting table 4121 protruding towards the first housing 411, and the mounting plate 45 is arranged on the surface of the mounting table 4121 facing the first housing 411, and the second fastener 413 passes through the mounting plate 45 and is fastened on the mounting table 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 also provided. Figures 14 to 17 Figure 6 The shape of the mounting table 4121 is designed to reduce the space occupation in the air inlet duct part 4125 and reduce the obstruction to the air flow path. For example, the mounting table 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 part 4125, so the thickness is set to be small, which can reduce the obstruction to the air flow.

[0194] As shown in FIG. 4A and FIG. 4B, in one embodiment, the second housing 412 is provided with one or more second wire passing holes 4126 corresponding to the heating element 441. The heating element 441 is connected to the external power supply by a power supply wire, and the second wire passing hole 4126 is used for the power supply wire to pass through.

[0195] As shown in FIG. 4A and FIG. 4B, in one embodiment, the second housing 412 is provided with one or more second wire passing holes 4126 corresponding to the heating element 441. The heating element 441 is connected to the external power supply by a power supply wire, and the second wire passing hole 4126 is used for the power supply wire to pass through. Figure 7 Figure 15 As shown in FIG. 4A and FIG. 4B, in one embodiment, the second housing 412 is provided with one or more second wire passing holes 4126 corresponding to the heating element 441. The heating element 441 is connected to the external power supply by a power supply wire, and the second wire passing hole 4126 is used for the power supply wire to pass through.

[0196] As shown in FIG. 4A and FIG. 4B, in one embodiment, the second housing 412 is provided with one or more second wire passing holes 4126 corresponding to the heating element 441. The heating element 441 is connected to the external power supply by a power supply wire, and the second wire passing hole 4126 is used for the power supply wire to pass through. Figure 16 ​​​As shown, the regeneration assembly 44 further comprises a regeneration fan 442, which is connected with the second shell 412, for example, the regeneration fan 442 can be arranged in the second shell 412 or connected with an end of the second shell 412 which is away from the second opening 4120. The regeneration fan 442 is used to provide flow power of air in the regeneration air duct.

[0197] Please refer to Figure 20 and Figure 15 As shown, the regeneration fan 442 is arranged at the third communication opening 1221 of the second side plate 122 and forms communication with the first air duct part 1111 inside the second side plate 122. The second shell 412 communicates with the regeneration fan 442 via the second communication opening 1212.

[0198] Please refer to Figure 16 , Figure 15 and Figure 20 As shown, the moisture absorption and removal system 4 further comprises a second driving member 43, which is fixed on the moisture absorption and removal shell 41 and is used to drive the moisture absorption and removal member 42 to rotate.

[0199] In an optional embodiment, the rotation central axis of the moisture absorption and removal member 42 and the rotation central axis of the drum 2 are arranged to be parallel to each other. 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 and the rotation central axis of the drum 2 are parallel to each other, the part 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, that is, the part 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, which realizes the maximum utilization of space in the equipment shell 1 and is conducive to ensuring the overall compact structure of the clothes treatment equipment 200.

[0200] In an embodiment, please refer to Figure 20 and Figure 20 As shown, the second driving member 43 is arranged on the first shell 411.

[0201] Alternatively, the second driving member 43 is arranged on a side surface of the first shell 411 which is away from the second shell 412. That is to say, 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.

[0202] Further, the second driving member 43 and the heating member 441 are located at the axial two sides of the moisture absorbing and removing member 42, which is beneficial to the axial two sides volume and space balance of the moisture absorbing and removing system 4, and beneficial to the flow symmetry of the air at the two sides of the moisture absorbing and removing system 4 in the main drying air duct 110, and reduces the pressure difference and air vortex caused by the space imbalance. In addition, the second driving member 43 and the heating member 441 are located at the axial two sides of the moisture absorbing and removing member 42, which is also beneficial to the weight balance of the two sides of the moisture absorbing and removing system 4.

[0203] As mentioned above, the first opening 4110 and the second opening 4120 are both fan-shaped, which can expose more surface of the moisture absorbing and removing member 42 for moisture adsorption. On this basis, in one embodiment, the second driving member 43 is staggered with the first opening 4110 in the axial direction of the moisture absorbing and removing member 42, please refer to Figure 20 As shown in the figure, the second driving member 43 is not aligned with the rotation center axis of the moisture absorbing and removing member 42, but offset from the first opening 4110 relative to the rotation center axis, that is, the second driving member 43 is offset from the first opening 4110 along the radial direction, and the second driving member 43 is arranged away from the first opening 4110 along the radial direction. The purpose of such arrangement is to reduce the obstruction of the second driving member 43 to the first opening 4110 in the axial direction of the moisture absorbing and removing member 42, and further reduce the obstruction to the air flow from the first heat exchanger 32 to the moisture absorbing and removing member 42, and improve the air speed and drying efficiency.

[0204] Please refer to Figure 16 As shown in the figure, in one embodiment, the second driving member 43 includes a second motor 432. The second motor 432 is arranged offset from the first opening 4110 relative to the rotation center axis of the moisture absorbing and removing member 42.

[0205] In an optional embodiment, the second motor 432 includes an eccentric motor, and the output shaft 4323 of the eccentric motor is coaxially connected with the moisture absorbing and removing member 42. In this way, the second driving member 43 is offset from the center axis of the moisture absorbing and removing member 42 as a whole, but the output shaft 4323 of the second driving member 43 is aligned with the center axis of the moisture absorbing and removing member 42. There is no need to arrange a transmission assembly between the second driving member 43 and the moisture absorbing and removing member 42, which can simplify the structure of the moisture absorbing and removing system 4. At the same time, the purpose of such eccentric arrangement is to reduce the obstruction of the second driving member 43 to the first opening 4110, increase the air passing area of the moisture absorbing part 4201, and improve the drying efficiency.

[0206] In another embodiment, the output shaft 4323 of the second drive member 43 is connected to the moisture absorption and desiccation member 42 via a transmission assembly (not shown), and the output shaft 4323 of the second drive member 43 is further offset away from the central axis of the moisture absorption and desiccation member 42 from the first opening 4110. The purpose of this arrangement is to further reduce the obstruction of the first opening 4110 by the second drive member 43, allowing the first opening 4110 to be opened as close as possible to the central axis of the moisture absorption and desiccation member 42, or even to achieve complete non-obstruction of the first opening 4110 by the second drive member 43.

[0207] Please see Figure 22 As shown, in one embodiment, the output shaft 4323 of the second drive member 43 has multiple flat surfaces 43230, which are circumferentially symmetrically distributed. When the output shaft 4323 is connected to the moisture absorption and desiccation member 42 and drives the moisture absorption and desiccation member 42 to rotate, the driving force is evenly distributed on the multiple flat surfaces 43230, which can increase the driving contact area between the output shaft 4323 and the moisture absorption and desiccation member 42. This allows the output shaft 4323 with a smaller diameter to drive the larger moisture absorption and desiccation member 42, and reduces wear and fatigue damage to both the output shaft 4323 and the moisture absorption and desiccation member 42.

[0208] Except for 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 an external power source to the rotating assembly. The motor housing 4321 is fixedly connected to the end face of the first housing 411 facing away from the second housing 412.

[0209] In one embodiment, please refer to Figure 20 As shown, the outer surface of the motor housing 4321 is non-circular, and a protrusion 4322 is formed corresponding to the electronic control unit protruding outward. Based on this protrusion 4322, as... Figure 20 , Figure 20 As shown, a limiting groove 4112 is provided on the first housing 411 corresponding to the protrusion 4322. The inner wall of the limiting groove 4112 is used to abut against the limiting part 4311 along the rotation direction of the moisture-absorbing and dehumidifying component 42 to restrict the rotation of the limiting part 4311. That is, the limiting groove 4112 and its limiting wall are used to prevent the motor housing 4321 from rotating with the rotating assembly, so that the motor housing 4321 remains fixed on the first housing 411. In an optional embodiment, the inner wall of the limiting groove 4112 is provided on both circumferential sides of the protrusion 4322.

[0210] In one embodiment, please refer to... Figure 16As shown, the second driving member 43 further comprises a sealed housing 431, a motor housing 4321 of the second motor 432 is arranged in the sealed housing 431, and the sealed housing 431 is sealingly connected to the side surface of the first housing 411 away from the second housing 412. By additionally arranging the sealed housing 431, the second motor 432 is integrally protected and sealed in the sealed housing 431, which can further reduce the influence of water vapor in the main drying air duct 110 on the second driving member 43.

[0211] Specifically, as shown in Figure 22 , the sealed housing 431 is provided with a plurality of second fixing ears 4312, and the second fixing ears 4312 are fixedly connected to the surface of the first housing 411 by fasteners (such as bolts, screws, etc.).

[0212] Optionally, as shown in Figure 18 , the second driving member 43 further comprises a sealing washer 434, the sealing washer 434 is arranged between the sealed housing 431 and the side surface of the first housing 411 away from the second housing 412, and surrounds the output shaft 4323. The sealed housing 431 is fixed on the first housing 411 by fasteners (such as bolts, screws, etc.). The sealing washer 434 is compressed between the sealed housing 431 and the first housing 411, so as to maintain the sealing connection between the sealed housing 431 and the first housing 411, and further reduce the possibility of water vapor entering the sealed housing 431.

[0213] Correspondingly, as shown in Figure 19 , the sealed housing 431 is outwardly convexly provided with a limiting portion 4311 corresponding to the protruding portion 4322, the protruding portion 4322 is located in the limiting portion 4311, and the limiting portion 4311 is located in the limiting groove 4112. The shape of the limiting groove 4112 is adapted to the shape of the limiting portion 4311, and the shape of the limiting portion 4311 is adapted to the shape of the protruding portion 4322.

[0214] As shown in Figure 18 and Figure 18 , the side end surface of the first housing 411 away from the second housing 412 is axially recessed to form a motor mounting groove 4111 facing the second housing 412, and a part of the sealed housing 431 and the sealing washer 434 are arranged in the motor mounting groove 4111. The purpose of such arrangement is that, on the one hand, the shape of the motor mounting groove 4111 is adapted to the shape of the sealing washer 434 and the sealed housing 431, which is beneficial to the overall rapid positioning of the second driving member 43 during installation of the second driving member 43, and on the other hand, the output shaft 4323 can be as close as possible to the moisture absorbing and discharging member 42 in the axial direction, which is beneficial to reducing the deformation degree of the output shaft 4323, ensuring the transmission efficiency between the output shaft 4323 and the moisture absorbing and discharging member 42, and reducing the wear of the output shaft 4323 and the moisture absorbing and discharging member 42.

[0215] Next, please refer to Figure 18and Figure 18 As shown, the moisture-absorbing and dehumidifying component 42 of this application embodiment is introduced.

[0216] like Figure 18 As shown, the moisture-absorbing and desiccant component 42 includes a moisture-absorbing and desiccant medium layer 421, a first fixed bracket 422, and a shaft 427. The moisture-absorbing and desiccant medium layer 421 is fixed on the first fixed bracket 422, and the shaft 427 passes through the first fixed bracket 422 and the moisture-absorbing and desiccant medium layer 421. One end of the shaft 427 is also connected to the output shaft 4323 of the second drive component 43, so that the second drive component 43 can drive the moisture-absorbing and desiccant medium layer 421 to rotate.

[0217] Understandably, the first fixed bracket 422 is configured to have air passages corresponding to the first opening 4110 and the second opening 4120, so as to expose a portion of the two axial end faces of the moisture absorption and desiccation medium layer 421.

[0218] In order to conveniently and effectively fix the moisture-absorbing and desiccant layer 421 and to maximize the area of ​​the air passage, in one embodiment, the first fixing bracket 422 covers at least a portion of the outer peripheral surface of the moisture-absorbing and desiccant layer 421 and abuts against at least one axial end face of the moisture-absorbing and desiccant layer 421.

[0219] In one embodiment, the first fixing bracket 422 is configured to cover at least a portion of the outer peripheral surface of the moisture-absorbing and desiccant layer 421 and at least abut against the axial end face of the moisture-absorbing and desiccant layer 421 facing the first heat exchanger 32. This configuration is intended to allow the shaft 427 and the moisture-absorbing and desiccant layer 421 to be connected via the first fixing bracket 422, since the second driving member 43 is located on the side of the moisture-absorbing and desiccant layer 421 facing the first heat exchanger 32. Thus, the outer peripheral surface of the shaft 427 does not need to directly interact with the moisture-absorbing and desiccant layer 421; instead, the force is distributed across more locations on the moisture-absorbing and desiccant layer 421 via the first fixing bracket 422, preventing the force from directly acting on the center of the moisture-absorbing and desiccant layer 421 and causing damage.

[0220] like Figure 19 As shown, in one embodiment, the first fixed bracket 422 includes a first plate 4231, a first inner fixing part 4241, and a plurality of connecting parts 4242. The first plate 4231 is annular and abuts against at least a portion of the outer peripheral surface of the moisture-absorbing and desiccant layer 421. The inner fixing part 4241 is disposed inside the first plate 4231 and abuts against the side end face of the moisture-absorbing and desiccant layer 421 facing the first heat exchanger 32. The plurality of connecting parts 4242 are arranged circumferentially at intervals and radially connect the first plate 4231 and the inner fixing part 4241. The shaft 427 is fixedly inserted through the inner fixing part 4241 and the moisture-absorbing and desiccant layer 421.

[0221] The first plate body 4231 is used to protect and abut at least part of the outer circumferential surface of the moisture absorbing and releasing medium layer 421, the inner fixing part 4241 is used to be connected with the shaft member 427, the connecting part 4242 is used to fixedly connect the first plate body 4231 and the inner fixing part 4241 together, and the through air holes are formed between the connecting part 4242. During the rotation of the moisture absorbing and releasing member 42, the through air holes are continuously communicated with the first opening 4110 and the air outlet air duct part 4115.

[0222] As shown in Figure 18 , the inner fixing part 4241 is provided with a connecting hole 42410 which penetrates through in the axial direction, the inner circumferential wall of the connecting hole 42410 is provided with at least one notch 42411, and the outer circumferential surface of the shaft member 427 is provided with a protruding part 4275 which cooperates with the notch 42411. That is, the inner circumferential wall of the connecting hole 42410 and the outer circumferential surface of the shaft member 427 are both designed as non-circular surfaces, and are in concave-convex cooperation, thereby forming circumferential fixed connection.

[0223] In one embodiment, in order to facilitate the manufacturing of the first fixing support 422, as shown in Figure 19 , the first fixing support 422 comprises a separate first fixing ring 423 and a support part 424, that is, the first fixing ring 423 and the support part 424 are separately manufactured. The first fixing ring 423 comprises the first plate body 4231 and further comprises a second plate body 4232 which is connected with the first plate body 4231 and is used to abut the edge of the axial end surface of the moisture absorbing and releasing medium layer 421 which faces the first heat exchanger 32, and the support part 424 comprises the connecting part 4242 and the inner fixing part 4241, and the radial outer edge of the connecting part 4242 is located between the second plate body 4232 and the moisture absorbing and releasing medium layer 421. In this way, the inner fixing part 4241 and the connecting part 4242 can be manufactured conveniently, the structure of the first fixing ring 423 is simplified, and the manufacturing is facilitated.

[0224] Further, in order to facilitate the manufacturing and installation of the support part 424 and avoid the radial outer end of the plurality of spaced connecting parts 4242 from being bent and deformed, in one embodiment, as shown in Figure 18 , the support part 424 further comprises a support outer ring 4243 which is connected between the radial outer ends of the connecting parts 4242, and the support outer ring 4243 is located between the second plate body 4232 and the moisture absorbing and releasing medium layer 421, as shown in Figure 18 .

[0225] As shown in Figure 18 and Figure 18As shown, the outer edge of the bracket outer ring 4243 is annularly provided with a first sunken groove 42430 penetrating the outer circumferential surface of the bracket outer ring 4243, and the second plate body 4232 is arranged in the first sunken groove 42430. The purpose of such arrangement is that, on the one hand, the first sunken groove 42430 serves as a reinforcing structure, which can enhance the strength of the bracket outer ring 4243 as a whole and avoid deformation of the bracket outer ring 4243; on the other hand, on the side facing the first heat exchanger 32, the height difference between the bracket outer ring 4243 and the second plate body 4232 can be small, or even can be substantially flush.

[0226] Optionally, the outer circumferential surface of the bracket outer ring 4243 is provided with a concave-convex limiting structure (not shown), and the inner circumferential surface of the first plate body 4231 can also be designed with a concave-convex limiting structure matched therewith, so as to facilitate the manufacturing and keep the circumferential fixed connection of the bracket outer ring 4243 and the first fixed ring 423.

[0227] As shown in Figure 18 The second sunken groove 42413 is arranged on the inner fixed part 4241. Similarly, the second sunken groove 42413 can enhance the strength of the inner fixed part 4241 and reduce the risk of deformation of the inner fixed part 4241.

[0228] As shown in Figure 18 In order to reduce the obstruction to the first opening 4110, the number of the connecting parts 4242 should be as small as possible, and the circumferential width of the connecting parts 4242 should be as small as possible. On this basis, in order to improve the strength of each connecting part 4242, each connecting part 4242 is provided with a recessed area 42420. The recessed area 42420 serves as a reinforcing structure and can improve the anti-deformation ability of the connecting part 4242.

[0229] Further, as shown in Figure 18 Each connecting part 4242 is provided with one or more radially spaced through holes 42421. On the basis of ensuring the anti-deformation ability of the connecting part 4242, the through holes 42421 further increase the area of the air passing hole on the first fixed bracket 422.

[0230] Among them, the plurality of through holes 42421 are arranged at intervals on each connecting part 4242, so that the area of each through hole 42421 can be smaller, and the anti-deformation ability of each connecting part 4242 is improved.

[0231] Please refer to Figure 19As shown, the shaft member 427 comprises a coaxially connected first shaft segment 4271 and a second shaft segment 4273, the first shaft segment 4271 is provided with a first abutting portion 4272 in the radial direction, and the second shaft segment 4273 is provided with a second abutting portion 4274 in the radial direction. The first abutting portion 4272 and the second abutting portion 4274 are respectively located on the axial sides of the moisture absorption and exhaust medium layer 421. The first shaft segment 4271 and the second shaft segment 4273 are separately manufactured and connected from the axial sides of the moisture absorption and exhaust medium layer 421. The first abutting portion 4272 and the second abutting portion 4274 abut the axial sides of the moisture absorption and exhaust medium layer 421 with a large area, and exert a certain compression force on the moisture absorption and exhaust medium layer 421.

[0232] As shown in Figure 18 , the second sink groove 42413 is designed in a shape that matches the shape of the first abutting portion 4272, and the first abutting portion 4272 is located in the second sink groove 42413.

[0233] In one embodiment, referring to Figure 19 , the moisture absorption and exhaust member 42 further comprises a second fixed support 425, which is arranged on the side of the moisture absorption and exhaust shell 41 facing the second shell 412, and the second fixed support 425 is fixedly connected with the first fixed support 422. The second fixed support 425 is used to abut at least part of the outer circumferential surface of the moisture absorption and exhaust medium layer 421 and the side end surface away from the first shell 411.

[0234] In this way, the first fixed support 422 and the second fixed support 425 can abut and compress the two axial end surfaces of the moisture absorption and exhaust medium layer 421, and protect the outer circumferential surface of the moisture absorption and exhaust medium layer 421.
