[0086] To illustrate the technical solutions described in the present application, the following will be described in detail in combination with specific drawings and embodiments.

[0087] Please refer to Figures 1 to 4 The embodiment of the present application provides a clothes processing apparatus 200.

[0088] Based on the normal working state of the clothes processing apparatus 200, for the purpose of description and understanding, "up", "down", "left", "right", "front", "back" are defined here, 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".

[0089] As Figures 1 to 4 shown, the clothes processing apparatus 200 includes an apparatus shell 1, and a drying module 100, a first driving member 5 and a drum 2 arranged in the apparatus shell 1. The first driving member 5 is connected with the drum 2 and used to drive the drum 2 to rotate.

[0090] As Figure 2 , Figure 3 and Figure 4 shown, the apparatus shell 1 can include a plurality of outer standing plates 15 connected with each other to surround the drying module 100. For example, the plurality of outer standing plates 15 of the apparatus shell 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 back side plate, etc. In other embodiments, the plurality of outer standing plates 15 can have other numbers and be connected in other orientations.

[0091] Please refer to Figure 2 , Figure 3 and Figure 4 , and Figure 8 shown, 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 clothes processing space 22.

[0092] Referring to Figure 2 and Figure 3As shown, the device housing 1 can further include a first support 16 and a second support (not shown), the first support 16 being arranged between the front side plate and the drum 2, and the second support (not shown) being arranged between the rear side plate and the drum 2, the axial ends of the drum 2 being rotatably mounted between the first support 16 and the second support. In some embodiments, the second support can be integrally arranged with the rear side plate.

[0093] In one embodiment, the air inlet 21 of the drum 2 can be arranged towards the front, i.e. towards the first support 16.

[0094] As shown in Figure 5 and Figure 6 , the drying module 100 can include a base assembly 11, the base assembly 11 being arranged below the drum 2, and a plurality of outer side plates 15 being connected to the periphery of the base assembly 11 to define the drum 2 therebetween.

[0095] As shown in Figure 5 , Figure 6 and Figure 7 , in one embodiment, the laundry 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 configured to provide at least one cold source and at least one heat source, and 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 configured to perform primary moisture absorption and removal (secondary dehumidification) on the air flowing out of the drum 2.

[0096] As shown in Figure 6 , 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 flow direction of the refrigerant.

[0097] The refrigerant can include hydrofluorocarbons (HFCs), chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), or natural refrigerants (such as ammonia, carbon dioxide, hydrocarbons, etc.). The second heat exchanger 34 serves as a heat source for heating the air, so that high-temperature air enters the drum 2. The first heat exchanger 32 serves as a cold source for cooling and condensing the air flowing out of the drum 2.

[0098] 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 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. As shown in Figure 6 and Figure 7As shown, 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 accommodating cavity 112 of the base assembly 11.

[0099] In addition, please refer to Figure 5 As shown, the components such as the first driving member 5 that do not participate in the air circulation are also arranged in the accommodating cavity 112.

[0100] After passing through the first heat exchanger 32, the air has a reduced temperature, a reduced absolute humidity, and an increased relative humidity. After passing through the second heat exchanger 34, the air has an increased temperature and a reduced relative humidity.

[0101] In one embodiment, the first heat exchanger 32 comprises a first evaporator, and the second heat exchanger 34 comprises a condenser.

[0102] 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.

[0103] 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.

[0104] When the absolute humidity remains unchanged, a temperature drop will increase the relative humidity, and even possibly reach the saturated state of water vapor to produce condensation, i.e., produce condensate. When the absolute humidity remains unchanged, a temperature rise will reduce the relative humidity and increase the unsaturated degree of water vapor in the air.

[0105] Therefore, after passing through the second heat exchanger 34, the air becomes high-temperature and low-humidity (low absolute humidity and low relative humidity), and after re-entering the drum 2, it can effectively remove the moisture in the clothes.

[0106] The moisture absorption and removal system 4 is used for moisture absorption and removal (secondary dehumidification) of the air flowing out of the drum 2. At least a part of the moisture absorption and removal system 4 is arranged in the main drying air duct 110 and located between the first heat exchanger 32 and the second heat exchanger 34, for moisture absorption and removal of the low-temperature air after the first heat exchanger 32, to further reduce the absolute humidity and the relative humidity of the air.

[0107] Please refer to Figure 16 As shown, in some embodiments, the moisture absorption and removal system 4 at least comprises a moisture absorption and removal member 42, a moisture absorption and removal shell 41, and a regeneration assembly 44, the moisture absorption and removal member 42 is arranged in the moisture absorption and removal shell 41 and plays a moisture absorption and removal function.

[0108] Please refer to Figure 22As shown, the space in the moisture absorption and removal casing 41 is divided into a moisture absorption zone 4102 and a desorption zone 4101. Please refer to Figure 16 As shown, the moisture absorption and removal member 42 includes a moisture absorption portion 4201 in the moisture absorption zone 4102 and a desorption portion 4202 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 desorption energy (heat) for the moisture in the desorption portion 4202.

[0109] In some embodiments, the shape of the moisture absorption and removal casing 41 can be designed according to the actual working condition requirements, as long as it includes at least 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 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 desorption zone 4101 can more effectively and reasonably utilize the space.

[0110] In some embodiments, the moisture absorption and removal member 42 is arranged in the moisture absorption and removal casing 41, as long as it can play the function of moisture absorption and removal. The shape of the moisture absorption and removal member 42 is not limited, which can be a polygon such as a triangle or a square, or a wheel disc shape, such as Figure 16 and Figure 18 As shown, the design of the wheel disc-shaped moisture absorption and removal member 42 can make the moisture absorption and removal member 42 move circularly between the moisture absorption zone 4102 and the desorption zone 4101. The part of the moisture absorption and removal member 42 (i.e., the moisture absorption portion 4201) moving to the moisture absorption zone 4102 absorbs the moisture in the air, and then the part of the moisture absorption and removal member 42 (i.e., the desorption portion 4202) moving to the desorption zone 4101 desorbs the moisture. The part of the moisture absorption and removal member 42 (i.e., the desorption portion 4202) after desorption moves to the moisture absorption zone 4102 to absorb the moisture, which is cyclically repeated to remove the moisture in the air, thereby achieving the effect of moisture absorption and removal.

[0111] In some embodiments, the moisture absorbing and removing member 42 is a desiccant wheel member, and the desiccant wheel in the desiccant wheel member can be a honeycomb or corrugated wheel loaded with a desiccant, which can adsorb and desorb the absorbed water vapor to realize repeated desorption and regeneration. In some embodiments, the desiccant wheel 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 desiccant such as a molecular sieve, which is uniformly distributed between the fiber carriers and on the surface of the fiber carriers to realize adsorption of the moisture in the air flow. The desiccant can be, for example, a zeolite, a modified / synthetic zeolite, a molecular sieve (including but not limited to single-crystal molecular sieves or mixed-crystal molecular sieves such as A-type molecular sieves, X / Y-type molecular sieves, ZSM molecular sieves, Beta molecular sieves, etc.), a polymer desiccant, an alkali metal aluminosilicate (13X molecular sieve), lithium chloride, silica gel, modified silica gel, activated alumina, or other materials with moisture absorption properties.

[0112] In an optional embodiment, the moisture absorbing and removing member 42 is a molecular sieve desiccant wheel.

[0113] In an embodiment, the regeneration assembly 44 is a heating member for heating the air in the desorption area 4101. In an embodiment, the regeneration assembly 44 includes an electric heating member.

[0114] Then, please refer to Figure 6 , Figure 7 and Figure 8 , in an 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 and dehumidifying the high-temperature air after the desorption area 4202 to reduce the absolute humidity of the air after the desorption area 4202.

[0115] By using the third heat exchanger 33 as the cold source of the moisture absorbing and removing system 4, the internal heat circulation during the regeneration process of the moisture absorbing and removing system 4 can be further realized, and the high-temperature air can be prevented from being discharged to the outside of the equipment housing 1. The applicability of the laundry treatment apparatus 200 is more extensive.

[0116] In an embodiment, the third heat exchanger 33 includes a second evaporator.

[0117] In an 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. Please refer to Figure 6 andFigure 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.

[0118] 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 includes 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.

[0119] Please refer to Figure 6 As shown in the drawings, 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 absorption and removal shell 41 and the first air duct part 1111, and is used to accommodate the desorption part 4202 of the moisture absorption and removal part 42 and the third heat exchanger 33. The regeneration air duct and the main drying air duct 110 are functionally independent and structurally isolated.

[0120] Next, the base assembly 11 and the arrangement of the heat pump system 3 on the base assembly 11 will be described in detail.

[0121] Please refer to Figure 5 、 Figure 6 、 Figure 11 and Figure 12 As shown in the drawings, the base assembly 11 includes a base 12 and an upper cover 13, as shown in Figure 5 and Figure 6 The base 12 includes a bottom plate 120 and a first side plate 121 provided 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, that is, the upper end surface of the first side plate 121, to define the main drying air duct 110 described above.

[0122] In one alternative embodiment, as shown in Figure 7 and Figure 16As shown, 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 in which 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.

[0123] The purpose of such arrangement is to make the air flow straight in the part of the main drying air duct 110 in which the moisture absorption and removal member 42 is arranged, reduce the air reversing and the possibility of vortex, and make the air flow in the drying module 100 have high efficiency and small resistance, so that a complex isolation and sealing structure is not needed between the main drying air duct 110 and the moisture absorption and removal system 4, and the clothes treatment apparatus 200 has the advantages of fast drying speed and low energy consumption.

[0124] As shown in Figure 5 and Figure 6 In one embodiment, the base 12 further includes 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.

[0125] In one embodiment, the moisture absorption and removal shell 41 arranged in the main drying air duct 110 is provided with a second air duct part. The first air duct part 1111 and the second air duct part are in communication and constitute the regeneration air duct. The first air duct part 1111 is used for arranging the second heat exchanger 34.

[0126] It can be understood that, as far as the base assembly 11 is concerned, the main drying air duct 110 can not necessarily be provided with an obvious partition structure to divide the part for accommodating the moisture absorption and removal shell 41, but the moisture absorption and removal shell 41 arranged in the main drying air duct 110 itself internally defines another part of the regeneration air duct, i.e., the desorption area 4101.

[0127] 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 one embodiment, as shown in Figure 11 and Figure 12 The bottom plate 120 is provided with a water running channel 113 located in the main drying air duct 110, or the condensed water will drip to the upper surface of the bottom plate 120, and the part of the main drying air duct 110 located below can serve as the water running channel 113.

[0128] As Figure 5 , Figure 6 andFigure 11 As shown, the bottom plate 120 includes a water collecting box 123 outside the first side plate 121, and the first side plate 121 and / or the bottom plate 120 is provided with a first water outlet 1210, which is in communication with the water collecting box 123 and the water running channel 113. Also, as shown, Figure 11 As shown, the bottom surface of the water running channel 113 (i.e. the upper surface of the portion of the bottom plate 120 located inside the main drying air duct 110) gradually decreases in the direction towards the first water outlet 1210. In this way, the condensed water can automatically flow to the first water outlet 1210 and enter the water collecting box 123.

[0129] The water collecting box 123 can be provided in a drawer type, a screw type or other detachable water collecting structure, or can be drained into a sewer through a water pipe.

[0130] As shown, Figure 12 The third heat exchanger 33 inside the first air duct portion 1111 can also generate condensed water, and the condensed water drops onto the upper surface of the portion of the bottom plate 120 located inside the first air duct portion 1111, or in other words, the portion of the first air duct portion 1111 located below also serves as the water running channel 113. The second side plate 122 and / or the bottom plate 120 is provided with a second water outlet 1220. In the first air duct portion 1111, the upper surface of the bottom plate 120 gradually decreases in the direction towards the second water outlet 1220, and the second water outlet 1220 is in communication with the water collecting box 123. In an optional embodiment, according to the positional relationship between the first air duct portion 1111 and the main drying air duct 110, the first water outlet 1210 can be in communication with the main drying air duct 110 and the first water outlet 1210 in sequence.

[0131] As shown in Figure 6 , Figure 11 and Figure 12 In an embodiment, the base assembly 11 further includes a partition plate 14, which is arranged inside the main drying air duct 110 and is spaced apart from the upper surface of the bottom plate 120 to form the water running channel 113. The partition plate 14 is provided with at least one water leakage hole 141 at a position corresponding to the first heat exchanger 32. In this way, the first heat exchanger 32 and the second heat exchanger 34 can be carried on the partition plate 14, and the condensed water generated by the first heat exchanger 32 can enter the water running channel 113 through the water leakage hole 141.

[0132] As shown in Figure 6 , Figure 11 and Figure 12As shown, in one embodiment, the upper surface of the bottom plate 120 is provided with a plurality of raised blocks 124, which are used to support the isolation plate 14 at a certain height, i.e., the isolation plate 14 is arranged at the end surface of the raised blocks 124 facing the upper cover 13. Among them, in order to be able to uniformly support the isolation plate 14 at multiple positions, the raised blocks 124 are designed in different shapes and positions. For example, referring to Figure 6 As shown, a part of the raised blocks 124 (first raised blocks 1241) are arranged on the inner circumferential wall of the first side plate 121, which are used to support the edge of the isolation plate 14, and another part of the raised blocks 124 (a plurality of second raised blocks 1242) are arranged in the water running channel 113 and the main drying air duct 110, which are used to support the middle part of the isolation plate 14 at multiple points.

[0133] As shown in Figure 11 and Figure 12 , in one embodiment, a part of the raised blocks 124 (third raised blocks 1243) are arranged to enclose each other in the water running channel 113 and define a first mounting cavity 1240, which is arranged to accommodate a part of the moisture absorption and removal system 4, specifically, a part of the moisture absorption and removal housing 41. The isolation plate 14 is provided with a corresponding avoiding opening 143 corresponding to the first mounting cavity 1240, as shown in Figure 11 . In this way, the moisture absorption and removal system 4 can be partially located above the isolation plate 14 and partially located below the isolation plate 14, and is isolated from the water running channel 113. The purpose of this arrangement is that in the up-down direction, the moisture absorption and removal system 4 can be as close to the bottom plate 120 as possible, so as to lower the position of the moisture absorption and removal system 4, and thus lower the overall height of the clothes treatment equipment 200.

[0134] In an optional embodiment, the lower surface of the bottom plate 120 can be downwardly protruded corresponding to the first mounting cavity 1240, and the upper surface of the bottom plate 120 can be downwardly recessed corresponding to the first mounting cavity 1240, if allowed, as shown in Figure 6 and Figure 11 , so as to further lower the position of the moisture absorption and removal system 4.

[0135] Please refer to Figure 6 , the upper surface of the isolation plate 14 corresponding to the first heat exchanger 32 is designed as a downwardly recessed surface, and at least part of the water leakage hole 141 is arranged on the recessed 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 to the water running channel 113 below the isolation plate 14.

[0136] In addition, condensate water will also be generated around the first heat exchanger 32. Therefore, in one embodiment, please refer to Figure 6 and Figure 12As shown, the upper surface of the isolation plate 14 is provided with a water baffle 142, which is located on the side of the first heat exchanger 32 close to the moisture absorption and dehumidification system 4 and is spaced apart from the first heat exchanger 32. The water leakage hole 141 and the avoidance opening 143 are respectively located on the opposite sides of the water baffle 142. The purpose of such arrangement is that since the wind direction is from the first heat exchanger 32 to the moisture absorption and dehumidification system 4, there will be obvious condensate water in the part of the space downstream of the first heat exchanger 32, and the water baffle 142 can block part of the condensate water from the avoidance opening 143 and prevent the condensate water from entering the avoidance opening 143 and the first mounting cavity 1240. According to the height relationship between the concave surface and the water baffle 142, one or more water leakage holes 141 can be arranged on the side of the water baffle 142 close to the first heat exchanger 32, such as Figure 13 As shown.

[0137] As shown in Figure 6 and Figure 6 In one embodiment, the isolation plate 14 is provided with a downwardly extending flange 144 around the periphery of the avoidance opening 143. The flange 144 can be in a closed enclosure style. Therefore, the flange 144 is located in the first mounting cavity 1240. The purpose of such arrangement is that the flange 144 can play a guiding role for the moisture absorption and dehumidification system 4 when the moisture absorption and dehumidification system 4 is assembled. In addition, through the interference fit between the flange 144 and the first pad, the condensate water in the water channel 113 can be further prevented from entering the first mounting cavity 1240.

[0138] In one embodiment, the isolation plate 14 can be fixedly connected with at least one pad 124 by fasteners, for example, fixedly connected with the third pad 1243 by fasteners. The fasteners can be bolts, screws, etc., or other structures that can be fixed.

[0139] In one embodiment, the lower surface of the isolation plate 14 is connected with at least one pad 124 through a limiting fit structure. For example, the upper surface of at least the first pad 1241 is provided with a limiting structure (not shown), and the lower surface of the isolation plate 14 is provided with a matching structure (not shown) corresponding to the limiting structure. The limiting structure can be a groove or a protrusion, and the matching structure can be a protrusion or a groove. Through the concave-convex fit between the upper surface of the first pad 1241 and the lower surface of the isolation plate 14, the installation stability of the isolation plate 14 on the pad 124 can be further ensured.

[0140] In other embodiments, other pads 124 and the isolation plate 14 can also be connected through fasteners and / or limiting fit structures. For example, the third pad 1243 is connected with the isolation plate 14 through fasteners, and for example, the second pad 1242 is connected with the isolation plate 14 through a limiting fit structure.

[0141] Please refer to Figure 7 As shown in

[0142] In addition, the first side plate 121, the second side plate 122 and the upper cover 13 are detachably connected. Specifically, the first side plate 121, the second side plate 122 and the upper cover 13 are fastened together by fasteners (such as screws or bolts) to keep the sealing member compressed between the sealing groove 1312 and the sealing protrusion 1311, thereby ensuring the sealing between the first side plate 121, the second side plate 122 and the upper cover 13. In other alternative embodiments, the first side plate 121, the second side plate 122 and the upper cover 13 can be connected together by other detachable ways.

[0143] 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. Figure 8 Figure 9 As shown in 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, the second side plate 122 is provided with a third communication port 1221, and 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.

[0144] Figure 6 As shown in The first driving member 5 is used to drive the rotation of the drum 2. Specifically, the first driving member 5 can include a first motor, a synchronous wheel and a first synchronous belt (not shown), the first motor drives the synchronous wheel to rotate, the synchronous wheel drives the synchronous belt to rotate, and the synchronous belt is sleeved on the outer circumferential surface of the drum 2 to drive the synchronous rotation of the drum 2.

[0145] In one embodiment, the first driving member 5 can include a second synchronous belt, a connecting arm and a tensioning member (all not shown), the connecting arm is movably arranged on the first motor and connected with the synchronous wheel, the second synchronous belt is connected between the synchronous wheel and the driving shaft of the first motor, one end of the tensioning member is connected with the synchronous wheel and the other end is connected on the bottom plate 120 to tension at least the second synchronous belt.

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.

[0147] 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.

[0148] 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.

[0149] 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.

[0150] 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.

[0151] Please refer to Figure 12 and Figure 16 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.

[0152] 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.

[0153] 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 effect for the 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.

[0154] 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 to the main circulating fan 6 to drive the main circulating fan 6 to rotate. The main circulating fan 6 is used to drive the air in the main drying air duct 110 to flow.

[0155] 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.

[0156] 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.

[0157] 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 as low as possible the height of the base assembly 11 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 as low as possible thin design of the upper cover 13 while ensuring the strength of the upper cover 13.

[0158] 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.

[0159] 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.

[0160] 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 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 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.

[0161] 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.

[0162] 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.

[0163] Please refer to 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.

[0164] 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.

[0165] Next, the moisture absorption and removal system 4 of the embodiment of the present application is introduced.

[0166] Please refer to Figure 22 、 Figure 14 、 Figure 16 and Figure 22 As shown, 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 also 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.

[0167] In one optional embodiment, please refer to Figure 15 、 Figure 16 and Figure 17 As shown, 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 to increase the air passing area of the moisture absorption part 4201 and improve the absorption efficiency of the moisture in the moisture absorption part 4201.

[0168] In one optional embodiment, please refer to 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.

[0169] 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.

[0170] 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.

[0171] 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.

[0172] 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,

[0173] 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.

[0174] 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.

[0175] Please refer to Figure 22 As shown in

[0176] The first opening 4110 is used for air intake, and the second opening 4120 is used for air exhaust. In this embodiment, the air flow direction in the desorption part 4202 is opposite to the air flow direction in the moisture absorption part 4201, which is conducive to improving the desorption efficiency.

[0177] In other alternative embodiments, the air exhaust air duct part 4115 can also be formed on the second shell 412, and the air intake air duct part 4125 is formed on the first shell 411, so that the air flow direction in the desorption part 4202 is the same as the air flow direction in the moisture absorption part 4201; or the first opening 4110 is used for air exhaust, and the second opening 4120 is used for air intake, so that the air flow direction in the desorption part 4202 is the same as the air flow direction in the moisture absorption part 4201.

[0178] Please refer to Figure 22 、 Figure 15 and Figure 16 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 arranged to be inclined 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.

[0179] 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 shell 41, avoiding vortex when the air reaches the surface of the first shell 411. Among them, Figure 16 The solid triangle arrow in

[0180] In one alternative embodiment, please refer to Figure 17 and Figure 22 The width of the first outer air guide surface 4114 gradually decreases in the direction toward the central axis of the moisture absorption and removal part 42. That is to say, from the axial direction of the moisture absorption and removal part 42, the first outer air guide surface 4114 is fan-shaped, which corresponds to the fan-shaped shape of the first opening 4110.

[0181] Please continue to refer to Figure 14 、 Figure 16 and Figure 22 , in one embodiment, the second shell 412 is also provided with a second outer air guide surface 4124, which is axially inclined to 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. The purpose of such arrangement is to guide the air in the main drying air duct 110, so that after the air flows out of the second opening 4120, it uniformly flows to the second heat exchanger 34, avoiding vortex between the second shell 412 and the second heat exchanger 34.

[0182] Further, this can ensure the flow speed of the air 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 processing equipment 200, and improve the drying efficiency of the clothes processing equipment 200.

[0183] In an optional embodiment, please refer to Figure 16 , the width of the second outer air guide surface 4124 gradually decreases in the direction towards the central axis of the moisture absorption and removal component 42. That is to say, from the axial direction of the moisture absorption and removal component 42, the second outer air guide surface 4124 is fan-shaped, which corresponds to the fan-shaped shape of the second opening 4120.

[0184] Please continue to refer to Figure 17 and Figure 22 , in one embodiment, the inner wall of the first shell 411 is provided with a first inner air guide surface 4113, which is axially inclined to 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. The first inner air guide surface 4113 is used to guide the air flowing out of the desorption part 4202 to change direction, avoiding 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.

[0185] Further, through the arrangement of the first inner air guide surface 4113, the flow speed inside the moisture absorption and removal system 4 is ensured, the desorption efficiency of the moisture in the desorption part 4202 is ensured, the energy consumption of the clothes processing equipment 200 is reduced, and the drying efficiency of the clothes processing equipment 200 is improved.

[0186] In an optional embodiment, the width of the first inner air guide surface 4113 gradually decreases in the direction towards the central axis of the moisture absorption and removal component 42. That is to say, from the axial direction of the moisture absorption and removal component 42, the first inner air guide surface 4113 is fan-shaped, which corresponds to the fan-shaped shape of the first opening 4110.

[0187] 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.

[0188] 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.

[0189] 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.

[0190] 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.

[0191] 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.

[0192] Specifically as Figure 17As shown, the heating element 441 is fixed to the inner wall 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 of the electric heating tube; for example, for an electric heating plate, the fastener can be adapted to the plate-shaped surface.

[0193] Please see Figure 22 As shown, in one embodiment, the heating element 441 is fixed to the inner wall surface of the second housing 412 by a mounting plate 45. Since the heating element 441 is substantially aligned with the second inner air guide surface 4123 in the axial direction, a mounting plate 45 is provided to fix the heating element 441 and maintain its orientation in order to keep the heating element 441 substantially parallel to the axial surface of the moisture absorption and desiccation component 42, thereby facilitating uniform heating of the desorption portion 4202 surface by the heating element 441. The mounting plate 45 may be flat, maintaining a large contact area with the heating element 441 to ensure the installation stability of the heating element 441.

[0194] Understandably, such as Figure 14 As shown, the mounting plate 45 has 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.

[0195] Specifically, please refer to Figures 14 to 17 and Figure 6 As shown, in one embodiment, the second inner air guide surface 4123 is provided with a mounting platform 4121 protruding towards the first housing 411. A mounting plate 45 is disposed on the surface of the mounting platform 4121 facing the first housing 411. A second fastener 413 passes through the mounting plate 45 and is fastened to the mounting platform 4121. In this way, the mounting plate 45 is spaced apart from the second inner air guide surface 4123, while also providing a mounting position for the mounting plate 45.

[0196] The shape of the mounting platform 4121 is designed to minimize its space occupation within the air intake duct 4125 and to reduce obstruction of the airflow path. For example, the mounting platform 4121 is generally plate-shaped, with its thickness direction being generally perpendicular to the airflow direction within the air intake duct 4125. Therefore, its thickness is set to be relatively small, which can reduce obstruction of airflow.

[0197] Please see Figure 7 and Figure 15 As shown, the second housing 412 has one or more second wiring holes 4126 corresponding to the heating element 441. The heating element 441 is connected to an external power source via a power cord, and the second wiring holes 4126 are used for power cords to pass through.

[0198] Please see Figure 16As 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.

[0199] As shown in 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.

[0200] As shown in 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.

[0201] 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.

[0202] In an embodiment, as shown in Figure 20 and Figure 20 The second driving member 43 is arranged on the first shell 411.

[0203] 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, 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.

[0204] 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.

[0205] As described 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, or in other words, 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.

[0206] 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.

[0207] 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.

[0208] In another embodiment, the output shaft 4323 of the second driving member 43 is connected to the moisture absorption and removal member 42 through a transmission assembly (not shown), and the output shaft 4323 of the second driving member 43 is further offset from the central axis of the moisture absorption and removal member 42 to the side away from the first opening 4110. In this way, the second driving member 43 can further reduce the obstruction of the first opening 4110, and the first opening 4110 can be as close as possible to the central axis of the moisture absorption and removal member 42, or even the second driving member 43 can not obstruct the first opening 4110 at all.

[0209] Referring to Figure 22 In one embodiment, the output shaft 4323 of the second driving member 43 has a plurality of flat surfaces 43230, which are distributed circumferentially symmetrically. When the output shaft 4323 is connected to and drives the moisture absorption and removal member 42 to rotate, the driving force is uniformly distributed on the plurality of flat surfaces 43230, which can increase the driving contact area between the output shaft 4323 and the moisture absorption and removal member 42, and can drive a larger moisture absorption and removal member 42 with a smaller diameter output shaft 4323, and the wear and fatigue damage of the output shaft 4323 and the moisture absorption and removal member 42 can be reduced.

[0210] In addition to the output shaft 4323, referring to Figure 20 The second motor 432 further includes a motor housing 4321, a rotating assembly (not shown) disposed in the motor housing 4321, and an electric control portion (not shown) disposed in the motor housing 4321 and connected to the rotating assembly. The output shaft 4323 passes through the motor housing 4321 and is connected to the rotating assembly, and the electric control portion is located on one side of the rotating assembly and is used to connect an external power source and the rotating assembly. The motor housing 4321 is fixedly connected to the side end surface of the first housing 411 away from the second housing 412.

[0211] In one embodiment, referring to Figure 20 The outer surface of the motor housing 4321 is a non-circular surface, and a protruding portion 4322 is formed outwardly protruding from the electric control portion. Based on the protruding portion 4322, as Figure 20 、 Figure 20 A limiting groove 4112 is provided on the first housing 411 corresponding to the protruding portion 4322, and the inner side wall of the limiting groove 4112 is used to abut against the limiting portion 4311 in the rotating direction of the moisture absorption and removal member 42 to limit the rotation of the limiting portion 4311. That is, the limiting groove 4112 and its limiting wall are used to block the rotation of the motor housing 4321 with the rotating assembly, so that the motor housing 4321 remains fixed on the first housing 411. In one optional embodiment, the inner wall of the limiting groove 4112 is arranged on both sides of the protruding portion 4322 in the circumferential direction.

[0212] In one embodiment, referring 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.

[0213] 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.).

[0214] 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.

[0215] 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.

[0216] 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.

[0217] Next, please refer to Figure 18and Figure 18 As shown, the moisture-absorbing and dehumidifying component 42 of this application embodiment is introduced.

[0218] 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.

[0219] 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.

[0220] 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.

[0221] 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.

[0222] 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.

[0223] 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.
