[0088] 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.

[0089] Please refer to Figures 1 to 4 As shown in the drawings, the present application provides a laundry treating apparatus 200.

[0090] For the convenience of description and understanding, the directions of "up", "down", "left", "right", "front" and "back" are defined herein based on the normal working state of the laundry treating apparatus 200. The side of the laundry treating apparatus 200 facing the user is "front", the side facing away from the user is "back", the side facing the ground is "down", the side facing away from the ground is "up", the side corresponding to the left hand of the user is "left", and the side corresponding to the right hand of the user is "right".

[0091] As shown in Figures 1 to 4 , the laundry treating apparatus 200 comprises an apparatus housing 1, and a drying module 100, a first driving member 5 and a drum 2 arranged in the apparatus housing 1. The first driving member 5 is connected with the drum 2 and used to drive the drum 2 to rotate.

[0092] As shown in Figure 2 , Figure 3 and Figure 4 , the apparatus housing 1 can comprise a plurality of outer standing plates 15 connected with each other to enclose the drying module 100. For example, the plurality of outer standing plates 15 of the apparatus housing 1 can comprise an upper side plate (or referred to as an upper cover plate), a front side plate (or referred to as a door plate), a left side plate, a right side plate and a back side plate, etc. In other embodiments, the plurality of outer standing plates 15 can be connected in other numbers and orientations.

[0093] Please refer to Figure 2 , Figure 3 and Figure 4 , and Figure 8 , the drum 2 is provided with an air inlet 21 and an air outlet 23, and the space between the air inlet 21 and the air outlet 23 serves as a laundry treating space 22.

[0094] Referring to Figure 2 and Figure 3 , the apparatus housing 1 can further comprise a first support member 16 and a second support member (not shown). The first support member 16 is arranged between the front side plate and the drum 2, and the second support member (not shown) is arranged between the back side plate and the drum 2. The drum 2 is rotatably mounted at both axial ends thereof between the first support member 16 and the second support member. In some embodiments, the second support member can be integrally arranged with the back side plate.

[0095] 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.

[0096] As shown in Figure 5 and Figure 6 , the drying module 100 can comprise a base assembly 11. The base assembly 11 is located below the drum 2, and the plurality of outer standing plates 15 are connected with the periphery of the base assembly 11 to enclose the drum 2.

[0097] Referring to Figure 5 ,Figure 6 and Figure 7 As shown in FIG. 1, in one embodiment, the laundry treating apparatus 200 further comprises a heat pump system 3 and a moisture absorbing and discharging system 4. The heat pump system 3 is configured to provide at least one cold source and at least one hot source, and to perform primary condensation and dehumidification and heating on the air flowing out of the drum 2. The moisture absorbing and discharging system 4 is configured to perform primary moisture absorbing and discharging (secondary dehumidification) on the air flowing out of the drum 2.

[0098] As shown in FIG. 2, the heat pump system 3 comprises, in sequence along the flow direction of the refrigerant, a compressor 31, a second heat exchanger 34, a throttling device 36, and a first heat exchanger 32. Figure 6 The refrigerant can be a hydrofluorocarbon (HFC), a chlorofluorocarbon (CFC), a hydrochlorofluorocarbon (HCFC), or a natural refrigerant (e.g., 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. The first heat exchanger 32 serves as a cold source to cool and condense the air flowing out of the drum 2.

[0099] In one embodiment, as shown in FIG. 3, 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.

[0100] Figure 6 and Figure 7 As shown in FIG. 4, in the heat pump system 3, the first heat exchanger 32 and the second heat exchanger 34 are arranged in the main drying air duct 110 along the air flow direction, and the compressor 31 and the throttling device 36 are arranged in the receiving cavity 112 of the base assembly 11. Figure 6 Figure 7 In addition, as shown in FIG. 5, components that do not participate in air circulation, such as the first driving member 5, are also arranged in the receiving cavity 112.

[0101] 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. Figure 5 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 ratio of the actual water vapor content in the air to the maximum water vapor content in the air at the same temperature.

[0104]

[0105] ​​​Relative humidity: refers to the percentage of the actual water vapor content (absolute humidity) in the air compared to the saturated water vapor content at the same temperature. It is a relative concept used to describe the degree to which the water vapor content in the air approaches saturation.

[0106] When absolute humidity remains constant, a decrease in temperature will cause relative humidity to increase, potentially even reaching water vapor saturation and causing condensation. Conversely, when absolute humidity remains constant, an increase in temperature will cause relative humidity to decrease, increasing the degree of unsaturation of water vapor in the air.

[0107] 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 from the clothes.

[0108] The moisture absorption and dehumidification system 4 is used to absorb and dehumidify the air flowing out of the drum 2 (secondary dehumidification). At least a portion of the moisture absorption and dehumidification system 4 is installed in the main drying air duct 110 and located between the first heat exchanger 32 and the second heat exchanger 34. It is used to absorb and dehumidify the low-temperature air after the first heat exchanger 32 to further reduce the absolute humidity and relative humidity of the air.

[0109] Please refer to the following: Figure 16 As shown, in some embodiments, the moisture absorption and dehumidification system 4 includes at least a moisture absorption and dehumidification component 42, a moisture absorption and dehumidification housing 41, and a regeneration component 44. The moisture absorption and dehumidification component 42 is disposed in the moisture absorption and dehumidification housing 41 and performs the function of moisture absorption and dehumidification.

[0110] Please refer to the following: Figure 22 As shown, the space inside the moisture absorption and desorption housing 41 is divided into a moisture absorption zone 4102 and a desorption zone 4101. Please refer to the relevant documentation. Figure 16 As shown, the moisture absorption and desiccation component 42 includes a moisture absorption section 4201 located in the moisture absorption zone 4102 and a desorption section 4202 located in the desorption zone 4101. The regeneration component 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 section 4202.

[0111] In some embodiments, the shape of the moisture-absorbing and desiccant housing 41 can be designed according to actual operating conditions, as long as it includes at least two functional areas: a moisture-absorbing area 4102 and a desorption area 4101. The shape of each functional area can also be designed according to actual needs, and can be square, triangular, circular, or fan-shaped, as long as the moisture-absorbing area 4102 and the desorption area 4101 are isolated from each other. In some embodiments, a fan-shaped moisture-absorbing area 4102 and desorption area 4101 can utilize space more effectively and rationally.

[0112] In some embodiments, the moisture absorbing and removing member 42 is arranged in the moisture absorbing and removing shell 41 as long as it can function as a moisture absorbing and removing member. The shape of the moisture absorbing and removing member 42 is not limited, which can be a polygon such as a triangle or a square, or a wheel disc. As shown in Figure 16 and Figure 18 , the moisture absorbing and removing member 42 in the form of a wheel disc can be designed to move in a cycle between the moisture absorbing area 4102 and the desorption area 4101. The part of the moisture absorbing and removing member 42 (i.e. the moisture absorbing part 4201) moving to the moisture absorbing area 4102 absorbs moisture in the air, and then the part of the moisture absorbing and removing member 42 (i.e. the desorption part 4202) absorbing moisture moves to the desorption area 4101 to desorb the moisture. The part of the moisture absorbing and removing member 42 desorbing the moisture moves to the moisture absorbing area 4102 again to absorb moisture, so as to remove the moisture in the air and achieve the effect of moisture absorption and removal.

[0113] In some embodiments, the moisture absorbing and removing member 42 is a dehumidifying wheel disc member. The dehumidifying wheel disc in the dehumidifying wheel disc member can be a honeycomb or corrugated wheel disc loaded with a moisture absorbing agent, which can absorb and desorb the absorbed water vapor to realize repeated desorption and regeneration. In some embodiments, the dehumidifying wheel 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 absorbing agent such as a molecular sieve, which is uniformly distributed between the fiber carriers and on the surface of the fiber carriers to realize the adsorption of the moisture in the air flow. The moisture absorbing agent can be, for example, a zeolite, a modified / synthetic zeolite, a molecular sieve (including but not limited to a single crystal molecular sieve such as an A-type molecular sieve, an X / Y-type molecular sieve, a ZSM molecular sieve, a Beta molecular sieve, or a mixed crystal molecular sieve, etc.), a high molecular weight moisture absorbing agent, an alkali metal aluminosilicate (13X molecular sieve), lithium chloride, silica gel, modified silica gel, activated alumina, etc.

[0114] In an optional embodiment, the moisture absorbing and removing member 42 is a molecular sieve dehumidifying wheel disc.

[0115] 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.

[0116] Then, please refer to Figure 6 , Figure 7 and Figure 8As shown, in one embodiment, the heat pump system 3 further comprises 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 section 4202, so as to reduce the absolute humidity of the air after the desorption section 4202.

[0117] By using the third heat exchanger 33 as the cold source of the moisture absorption and dehumidification system 4, the internal heat circulation during the regeneration process of the moisture absorption and dehumidification system 4 can be further achieved, and the high-temperature air can be prevented from being discharged outside the equipment shell 1. The laundry treatment equipment 200 has a wider applicability.

[0118] In one embodiment, the third heat exchanger 33 comprises a second evaporator.

[0119] 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.

[0120] 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.

[0121] Please refer to Figure 6 As shown, the base assembly 11 further comprises a regeneration air duct, which is at least formed by the desorption section 4101 in the moisture absorption and dehumidification shell 41 and the first air duct section 1111, and is used for accommodating the desorption section 4202 of the moisture absorption and dehumidification 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.

[0122] Next, the base assembly 11 and the arrangement of the heat pump system 3 on the base assembly 11 will be described in detail.

[0123] Please refer to Figure 5 ,Figure 6 、 Figure 11 and Figure 12 As shown in Figure 5 and Figure 6 , 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.

[0124] 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 element 42 are arranged in the main drying air duct 110, and the rotation center axis of the moisture absorption and removal element 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 element 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 element 42 is arranged. That is, the air passing through the moisture absorption and removal element 42 flows straight in the main drying air duct 110.

[0125] 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 element 42 is arranged, thereby reducing the possibility of air reversing and vortex, and the air passing efficiency of the drying module 100 is high and the air resistance is small, and 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.

[0126] As shown in 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.

[0127] 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.

[0128] 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 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.

[0129] The first heat exchanger 32 and the second heat exchanger 34 are arranged in the main drying air duct 110, i.e. on the upper surface of the bottom plate 120, and the first heat exchanger 32 produces condensate water. Therefore, as shown in Figure 11 and Figure 12 , the bottom plate 120 is provided with a water running channel 113 in the main drying air duct 110, or the condensate water drops on the upper surface of the bottom plate 120, and the space below the main drying air duct 110 can be used as the water running channel 113.

[0130] As shown in Figure 5 , Figure 6 and Figure 11 , 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 connected with the water running channel 113 and the water collecting box 123. As shown in Figure 11 , the bottom surface of the water running channel 113, i.e. the upper surface of the part of the bottom plate 120 in the main drying air duct 110, gradually decreases in the direction towards the first water outlet 1210. In this way, the condensate water can automatically flow to the first water outlet 1210 and enter the water collecting box 123.

[0131] The water collecting box 123 can be a drawer type, a screw type or other detachable water collecting structure, or can be connected with a water pipe to drain into a sewer.

[0132] As shown in Figure 12 , the third heat exchanger 33 in the first air duct part 111 also produces condensate water, and the condensate water drops on the upper surface of the part of the bottom plate 120 in the first air duct part 111, or the space below the first air duct part 111 is also used 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 part 111, 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 connected with the water collecting box 123. In an optional embodiment, according to the positional relationship between the first air duct part 111 and the main drying air duct 110, the first water outlet 1210 can be connected with the main drying air duct 110 and the first water outlet 1210 in sequence.

[0133] Please refer to Figure 6 , Figure 11 and Figure 12As shown, in one embodiment, the base assembly 11 further comprises a partition plate 14, which is arranged in the main drying air duct 110 and is spaced apart from the upper surface of the bottom plate 120 to form a 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 on the first heat exchanger 32 can enter the water running channel 113 through the water leakage hole 141.

[0134] As shown in Figure 6 , Figure 11 and Figure 12 , 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 partition plate 14 at a certain height, i.e., the partition plate 14 is arranged at the end face of the raised blocks 124 facing the upper cover 13. Among them, in order to be able to uniformly support multiple positions of the partition plate 14, the raised blocks 124 are designed according to different shapes and positions. For example, as shown in Figure 6 , 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 partition 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 in the main drying air duct 110, which are used to support the middle part of the partition plate 14 at multiple points.

[0135] As shown in Figure 11 and Figure 12 , in one embodiment, a part of the raised blocks 124 (third raised blocks 1243) are arranged in the water running channel 113 and surround each other to 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 partition plate 14 is provided with an 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 partition plate 14 and partially located below the partition plate 14 and be 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, thereby reducing the overall height of the clothes treatment apparatus 200.

[0136] 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.

[0137] Please refer toFigure 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.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] In one embodiment, at least one of the cushion blocks 124 is connected to the lower surface of the isolation plate 14 by a limiting fit structure. For example, the upper surface of at least the first cushion block 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 cushion block 1241 and the lower surface of the isolation plate 14, the installation stability of the isolation plate 14 on the cushion block 124 can be further ensured.

[0142] In other embodiments, other cushion blocks 124 can also be connected to the isolation plate 14 by fasteners and / or limiting fit structures. For example, the third cushion block 1243 is connected to the isolation plate 14 by a fastener, and for example, the second cushion block 1242 is connected to the isolation plate 14 by a limiting fit structure.

[0143] As shown in Figure 7 In one embodiment, the upper end surfaces of the first side plate 121 and the second side plate 122 are connected together with the lower end surface of the upper cover 13 by a sealing structure 131. The sealing structure 131 includes a sealing protrusion 1311 and a sealing groove 1312. For example, the upper end surfaces of the first side plate 121 and the second side plate 122 are provided with one of the sealing groove 1312 and the sealing protrusion 1311, and the lower end surface of the upper cover 13 is provided with the other of the sealing groove 1312 and the sealing protrusion 1311, and the sealing protrusion 1311 is located in the sealing groove 1312. In an optional embodiment, a sealing member (not shown), such as an elastic sealing strip, is provided between the sealing protrusion 1311 and the sealing groove 1312.

[0144] 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 pressed 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 optional embodiments, the first side plate 121, the second side plate 122, and the upper cover 13 can be connected together by other detachable means.

[0145] As shown in Figure 4 The second side plate 122 is connected to a part of the first side plate 121, or in other words, a part of the first side plate 121 is used to enclose the first air duct part 1111 with the second side plate 122. As shown in Figure 8 and Figure 9As shown, 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 dehumidification 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.

[0146] Please refer to Figure 6 As shown, the first driving member 5 is used to drive the rotation of the roller 2. The first driving member 5 can specifically 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 roller 2 to drive the synchronous rotation of the roller 2.

Generally, based on the positional relationship between the tensioning member and the synchronous wheel, the tensioning member is arranged to be inclined with respect to the up-down direction and the horizontal direction, and the chamfered arc 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-angled surface.

[0149] The rear side of the base 12 is used to be connected with a rear side plate. As Figure 11 shown, in one embodiment, the edge of the bottom plate 120 is provided with a plurality of guide blocks 126, the guide blocks 126 are located at the periphery of the first side plate 121, the side of the guide block 126 facing the first side plate 121 has a guide surface 1260, and the guide surface 1260 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.

[0150] Please refer to Figure 11 , Figure 2 andFigure 3 As shown, in one embodiment, the base 12 further comprises a third side plate 125 provided on the bottom plate 120 and outside the first side plate 121 and the second side plate 122, and the third side plate 125 defines a front air duct 1250. Figure 2 As shown, the third side plate 125 is provided with a fourth communication opening 1251 which is in communication with the main drying air duct 110, and an end surface of the third side plate 125 away from the bottom plate 120 defines a fifth communication opening 1252, and the second communication opening 1212 is used to communicate with the air outlet 23 of the drum 2.

[0151] In one embodiment, please refer to Figure 3 and Figure 2 As shown, the first support 16 is provided with a third opening 161 corresponding to the air inlet 21 of the drum 2, and the third opening 161 is in communication with and aligned with the air inlet 21 in the axial direction of the drum 2. During the rotation of the drum 2, the air inlet 21 always communicates with the third opening 161. The third opening 161 also communicates with the front air duct 1250, so that the clothes processing space 22 of the drum 2 is communicated to the front air duct 1250.

[0152] Please refer to Figure 3 and Figure 6 As shown, the first support 16 is provided with a third opening 161 corresponding to the air inlet 21 of the drum 2, and the third opening 161 is in communication with and aligned with the air inlet 21 in the axial direction of the drum 2. During the rotation of the drum 2, the air inlet 21 always communicates with the third opening 161. The third opening 161 also communicates with the front air duct 1250, so that the clothes processing space 22 of the drum 2 is communicated to the front air duct 1250.

[0153] Please refer to Figure 12 and Figure 16 As shown, the first support 16 is provided with a third opening 161 corresponding to the air inlet 21 of the drum 2, and the third opening 161 is in communication with and aligned with the air inlet 21 in the axial direction of the drum 2.

The third opening 161 also communicates with the front air duct 1250, so that the clothes processing space 22 of the drum 2 is communicated to the front air duct 1250.

[0154] Please refer to Figure 17 and Figure 6 As shown, in one embodiment, the upper cover 13 is provided with a first wire hole 132. The first wire hole 132 is used for power supply wires, signal wires and the like to pass through. In some embodiments, the regenerative assembly 44 comprises 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 wire is used to provide electric energy for the electric heating element.

[0155] As shown Figure 4 and Figure 6As shown, the edge of the upper cover 13 is provided with a plurality of fixed wire blocks 133 arranged at intervals. The fixed wire blocks 133 are used to provide fixing effect for the power supply wires, signal lines and the like that pass out of the first wire passing hole 132. The form of the fixed wire blocks 133 is not limited.

[0156] Please refer to Figure 12 As shown, in one embodiment, the clothes treatment apparatus 200 further comprises a main circulating fan 6, which is at least partially arranged in the main drying air duct 110, and the first driving member 5 is connected to the main circulating fan 6 to drive the main circulating fan 6 to rotate, and the main circulating fan 6 is used to drive the air in the main drying air duct 110 to flow.

[0157] In one embodiment, as Figure 6 As shown, the main circulating fan 6 is arranged downstream of the second heat exchanger 34 and is used to transport the air in the main drying air duct 110 to the air inlet 21 of the drum 2.

[0158] In one embodiment, the first driving member 5 is a double driving member, such as a double rotor motor, which has 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 be connected to the main circulating fan 6. In this way, one first driving member 5 can be used to provide the rotation of the drum 2 and the main circulating fan 6, thereby saving the structural cost and reducing the volume occupation.

[0159] Please continue to 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 / are 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 much as possible to reduce the height of at least the position of the base assembly 11 corresponding to 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 much as possible to design the upper cover 13 to be thin while ensuring the strength of the upper cover 13.

[0160] In one embodiment, any one of the base 12, the isolation plate 14 and the upper cover 13 can be a plastic piece, 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 relatively low thermal conductivity, and the heat exchange between them and the air in the main drying air duct 110 and the regenerative air duct is relatively low.

[0161] Next, please refer to Figure 10 , Figure 6 and Figure 8As 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 connected through the refrigerant pipe 35.

[0162] During the operation of the compressor 31, the suction and discharge of the refrigerant are constantly occurring, and thus the compressor 31 generates vibration. Generally, the vibration is mostly multi-directional vibration in the horizontal plane. In order to reduce the pulling and extruding 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, the refrigerant pipe 35 is preferably designed to have a plurality of pipe segments 351 connected in a relative bending manner in the horizontal direction and / or the vertical direction. Figure 10 As shown, in an embodiment, the refrigerant pipe 35 includes a plurality of pipe segments 351 connected in a relative bending manner in the horizontal direction and / or the vertical direction. For example, when the compressor 31 vibrates in the left-right direction and the first pipe segment 351 connected with the compressor 31 also extends in the left-right direction, the first pipe segment 351 will generate a movement amount in the left-right direction, and the second pipe segment 351 will be deflected or bent towards the left-right direction. For the pipe segments 351 connected in sequence and elongated (the length is greater than the outer diameter), the risk of breakage caused by deflection or bending is obviously reduced compared with the pulling and extruding in the length direction. When a plurality of pipe segments 351 are connected in a relative bending manner, the pulling and extruding of the refrigerant pipe 35 caused by the vibration of the compressor 31 will be significantly improved.

[0163] The relative bending connection of the adjacent pipe segments 351 in the horizontal direction means that the projections of the adjacent pipe segments 351 on the horizontal plane or on the bottom plate 120 are connected in a bending manner; and the relative bending connection of the adjacent pipe segments 351 in the vertical direction means that the projections of the adjacent pipe segments 351 in the vertical plane are connected in a bending manner.

[0164] In an 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 laundry treating apparatus 200, etc.

[0165] Please refer to Figure 15 and Figure 16As shown, in one embodiment, the shell of the compressor 31 is provided with a plurality of first fixing lugs 311, each of which is provided with a fixing hole 3110, and 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 described above. If the first fixing lug 311 is fixedly connected with the first fastener 37 without a gap, the first fixing lug 311 of the compressor 31 may be damaged during the continuous vibration of the compressor 31, 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 also be caused. In the embodiment of the application, the vibration of the compressor 31 is transmitted to the refrigerant pipe 35, and is buffered and consumed by the bent pipe section 351, thereby reducing the damage to the compressor 31 itself and reducing the vibration of the entire laundry treating apparatus 200.

[0166] In one optional embodiment, please refer to Figure 17 As 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 this 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 avoiding space 350 as described above.

[0167] Next, the moisture absorption and removal system 4 of the embodiment of the application will be introduced.

[0168] 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, such as Figure 14 、 Figure 16 and Figure 22As shown, the moisture absorption and removal shell 41 is further provided with a second opening 4120. The first opening 4110 and the second opening 4120 respectively expose a part 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 via the moisture absorption part 4201 of the moisture absorption and removal member 42. 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 in the air can be absorbed by the moisture absorption part 4201. The part of the moisture absorption and removal shell 41 corresponding to the part between the first opening 4110 and the second opening 4120 is the moisture absorption area 4102.

[0169] In an alternative 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 part of the first axial end surface of the moisture absorption and removal member 42. In this way, the first opening 4110 can be easily manufactured and has a larger area, which facilitates the increase of the air passing area of the moisture absorption part 4201 and the improvement of the moisture absorption efficiency in the moisture absorption part 4201.

[0170] In an alternative embodiment, as shown in Figure 22 , Figure 16 , Figure 21 and Figure 22 , the second opening 4120 is formed on the second axial end surface of the moisture absorption and removal shell 41, and the second opening 4120 exposes a part of the second axial end surface of the moisture absorption and removal member 42. Similarly, the second opening 4120 can be easily manufactured and has a larger area, which facilitates the increase of the air passing area of the moisture absorption part 4201 and the improvement of the moisture absorption efficiency in the moisture absorption part 4201.

[0171] 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 absorption and removal shell 41, and the second opening 4120 is formed on the second axial end surface of the moisture absorption and removal shell 41. Overall, the air passing area of the moisture absorption and removal shell 41 and the moisture absorption and removal member 42 is larger, which is conducive to the improvement of the moisture absorption efficiency, the reduction of the consumption of air kinetic energy, the reduction of energy consumption and the improvement of the drying efficiency.

[0172] Further alternatively, as shown in Figure 7 , Figure 7 and Figure 16As shown, the first opening 4110 and the second opening 4120 are communicated along the axial direction via the moisture absorption portion 4201 of the moisture absorption and removal 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 absorption and removal member 42. The air passes through the moisture absorption and removal member 42 along the axial direction, which has a larger air passing area and adsorption area, and has a smaller air resistance, which is beneficial to improve the flow speed of the air in the moisture absorption and removal system 4, thereby improving the moisture desorption efficiency and reducing the energy consumption.

[0173] In one embodiment, the first axial end surface and the second axial end surface of the moisture absorption and removal 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 absorption and removal 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 absorption and removal 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 absorption and removal 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 absorption and removal 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 absorption and removal member 42 allows a smaller diameter and volume to be designed, which is beneficial to reduce the overall volume of the moisture absorption and removal system 4 and the overall volume of the laundry treatment apparatus 200.

[0174] Please refer to Figure 17 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, Figure 21 The solid triangle arrow in the figure indicates the direction of the air. In the main drying air duct 110, at least part of the first heat exchanger 32, the moisture absorption and removal system 4, and the second heat exchanger 34 is generally a square space. This allows the air to pass through the first heat exchanger 32, the moisture absorption and removal system 4, and the second heat exchanger 34 in sequence, avoiding the change of direction and vortex of the air, and the air has the highest flow efficiency between the first heat exchanger 32, the moisture absorption and removal system 4, and the second heat exchanger 34. In addition, in the moisture absorption and removal member 42, the flow direction of the air is completely parallel to the direction of the air permeable hole of the moisture absorption and removal member 42, and the air dried by the moisture absorption and removal member 42 can pass straight out, which minimizes the loss of air kinetic energy and wind speed. According to specific needs, the first heat exchanger 32, the moisture absorption and removal system 4, and the second heat exchanger 34 can be arranged at a certain distance along the axial direction of the moisture absorption and removal member 42 in the main drying air duct 110, or can not be arranged at a distance, which does not affect the operation of each.

[0175] Please refer to Figure 22 、 Figure 16 、 Figure 17 and Figure 22 , the moisture absorption and moisture removal shell 41 includes a first shell 411 and a second shell 412, the first shell 411 and the second shell 412 are connected on both sides of the axial direction of the moisture absorption and moisture removal piece 42 to limit the moisture absorption and moisture removal piece 42 inside. The first opening 4110 is provided on the first shell 411, and the second opening 4120 is provided on the second shell 412. The first shell 411 and the second shell 412 can be connected by fasteners (such as bolts, screws) and the like. In addition, please refer to Figure 22 and Figure 14 , in an optional embodiment, according to the shape of the first shell 411 and the second shell 412, at positions where it is not convenient to set the fasteners, a ring-shaped connecting piece 414 can also be sleeved on the first shell 411 and the second shell 412 to achieve further fixed connection of the first shell 411 and the second shell 412.

[0176] Please refer to 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 moisture removal piece 42 to form a second air duct part, that is, the desorption area 4101 of the moisture absorption and moisture removal shell 41. In this way, the moisture absorption and moisture removal shell 41 is at least partially arranged in the main drying air duct 110, and the second air duct part in the moisture absorption and moisture removal shell 41 is in communication with the first air duct part 1111 outside the main drying air duct 110, thereby forming a regeneration air duct.

[0177] Please refer to Figure 22 , the first shell 411 forms an air outlet air duct part 4115, and the second shell 412 forms an air inlet air duct part 4125, the air inlet air duct part 4125 and the air outlet air duct part 4115 are in communication through the desorption part 4202 of the moisture absorption and moisture removal piece 42, and constitute the above-mentioned second air duct part. That is, in the regeneration air duct, the air in the second shell 412 passes through the desorption part 4202, enters the first shell 411, and then reaches the third heat exchanger 33, and finally circulates back to the second shell 412.

[0178] The first opening 4110 is used for air inlet, and the second opening 4120 is used for air outlet. In this embodiment, the flow direction of the air in the desorption part 4202 is opposite to that in the moisture absorption part 4201, which is beneficial to improve the desorption efficiency.

[0179] In other optional embodiments, the air outlet air duct part 4115 can also be formed on the second shell 412, and the air inlet air duct part 4125 is formed on the first shell 411, so that the air flow direction in the desorption part 4202 and the flow direction in the moisture absorption part 4201 are the same; 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 and the flow direction in the moisture absorption part 4201 are the same.

[0180] 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, which is arranged to be inclined to the axial direction of the moisture absorption and removal part 42, specifically, it is inclined to the desorption part 4202 in the direction towards the central axis of the moisture absorption and removal part 42.

[0181] 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 the figure indicates the direction of the air. 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 treatment equipment 200, and improve the drying efficiency of the clothes treatment equipment 200.

[0182] In one optional embodiment, please refer to Figure 17 and Figure 22 , 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 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.

[0183] 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 arranged to be inclined to the axial direction of the moisture absorption and removal part 42, specifically, it is inclined to the desorption part 4202 in the direction towards the central axis of the moisture absorption and removal part 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 from 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.

[0184] Further, the air flow speed in the main drying air duct 110 can be ensured, the moisture adsorption efficiency in the moisture absorption part 4201 can be ensured, the energy consumption of the clothes treatment equipment 200 can be reduced, and the drying efficiency of the clothes treatment equipment 200 can be improved.

[0185] In an optional embodiment, as shown in Figure 16 As shown in , the second outer air guide surface 4124 gradually decreases in width in the direction towards the central axis of the moisture absorption and removal part 42. That is to say, as viewed in the axial direction of the moisture absorption and removal part 42, the second outer air guide surface 4124 is in the shape of a sector, which corresponds to the sector shape of the second opening 4120.

[0186] Figure 17 As shown in Figure 22 In an embodiment, as shown in , the first inner air guide surface 4113 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 towards the central axis of the moisture absorption and removal part 42. The first inner air guide surface 4113 is used to guide the air flowing out of the desorption part 4202 to change direction, so as to avoid vortex and wind energy loss caused by sharp change of direction when the air flows from the desorption part 4202 to the third heat exchanger 33. Optionally, the first outer air guide surface 4114 is generally parallel to the first inner air guide surface 4113.

[0187] Further, through the arrangement of the first inner air guide surface 4113, the air flow speed in the moisture absorption and removal system 4 can be ensured, the moisture desorption efficiency in the desorption part 4202 can be ensured, the energy consumption of the clothes treatment equipment 200 can be reduced, and the drying efficiency of the clothes treatment equipment 200 can be improved.

[0188] In an optional embodiment, the first inner air guide surface 4113 gradually decreases in width in the direction towards the central axis of the moisture absorption and removal part 42. That is to say, as viewed in the axial direction of the moisture absorption and removal part 42, the first inner air guide surface 4113 is in the shape of a sector, which corresponds to the sector shape of the first opening 4110.

[0189] As shown in Figure 17 , Figure 22 and Figure 16 In an embodiment, as shown in , the second inner air guide surface 4123 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 towards the central axis of the moisture absorption and removal part 42. The second inner air guide surface 4123 is used to guide the air flowing out of the desorption part 4202 to change direction, so as to avoid vortex and wind energy loss caused by sharp change of direction when the air flows from the third heat exchanger 33 to the desorption part 4202. Optionally, the second outer air guide surface 4124 is generally parallel to the second inner air guide surface 4123.

[0190] In an optional embodiment, referring to Figure 17 As shown, 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 in 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.

[0191] In an embodiment, referring to Figure 16 As shown, 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 in a symmetrical manner about the radial plane of the moisture absorbing and removing member 42.

[0192] In an embodiment, referring to Figure 17 and Figure 17 As shown, 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 portion 4125, to heat the air entering the desorption portion 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 to the inner wall surface of the second shell 412.

[0193] In an embodiment, referring to Figure 17 As shown, the heating member 441 is fixed to 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 portion 4125 is guided by the second inner air guide surface 4123 and then heated by the heating member 441. The purpose of this arrangement is that the heating member 441 is closer to the surface of the desorption portion 4202 of the moisture absorbing and removing member 42, and the heat is more easily transferred to the moisture absorbing and removing member 42, thereby improving the energy utilization and the desorption efficiency of the desorption portion 4202.

[0194] Specifically, as shown Figure 17 The heating member 441 is fixed to the inner wall surface of the second shell 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 member 441. For example, for an electric heating pipe, the fastener can be adapted to the pipe surface of the electric heating pipe, and for an electric heating plate, the fastener can be adapted to the plate surface.

[0195] In an embodiment, referring to Figure 22As shown, in one embodiment, the heating member 441 is fixed on the inner wall surface of the second housing 412 by a mounting plate 45. Since the heating member 441 is generally aligned with the second inner air guide surface 4123 in the axial direction, in order to keep the heating member 441 generally parallel to the axial surface of the moisture absorbing and removing member 42 so as to facilitate the uniform heating of the heating member 441 to the surface of the desorption portion 4202, a mounting plate 45 is provided to fix the heating member 441 and keep the orientation of the heating member 441. The mounting plate 45 can be in the form of a flat plate, and keep a large contact area between the heating member 441 to ensure the stability of the installation of the heating member 441.

[0196] As can be understood, Figure 14 the mounting plate 45 is in a porous structure so as not to affect the flow of air from the second inner air guide surface 4123 to the heating member 441.

[0197] Specifically, as shown in Figures 14 to 17 and Figure 6 in one embodiment, the second inner air guide surface 4123 is provided with a mounting platform 4121 protruding towards the first housing 411, the mounting plate 45 is arranged on the surface of the mounting platform 4121 facing the first housing 411, and the second fastener 413 passes through the mounting plate 45 and is fastened on the mounting platform 4121. In this way, the mounting plate 45 can be arranged spaced apart from the second inner air guide surface 4123, and the mounting position of the mounting plate 45 is provided.

[0198] The mounting platform 4121 is designed in a shape to reduce the space occupation in the air inlet duct portion 4125 and reduce the obstruction to the flow path of air. For example, the mounting platform 4121 is generally in the form of a thin plate, and the thickness direction is generally perpendicular to the air flow direction in the air inlet duct portion 4125, so the thickness is set to be small, which can reduce the obstruction to the air flow.

[0199] As shown in Figure 7 and Figure 15 the second housing 412 is provided with one or more second wire passing holes 4126 corresponding to the heating member 441. The heating member 441 is connected to the external power supply through the power supply wire, and the second wire passing hole 4126 is used for the power supply wire and the like to pass through.

[0200] As shown in Figure 16 the regeneration assembly 44 further comprises a regeneration fan 442, and the regeneration fan 442 is connected to the second housing 412, for example, the regeneration fan 442 can be arranged in the second housing 412, or connected to the end of the second housing 412 away from the second opening 4120. The regeneration fan 442 is used to provide the flow power of air in the regeneration air duct.

[0201] As shown in Figure 20 and Figure 15As shown, the regenerative blower 442 is arranged at the third communication opening 1221 of the second side plate 122 and is in communication with the first air duct portion 1111 inside the second side plate 122. The second shell 412 is in communication with the regenerative blower 442 via the second communication opening 1212.

[0202] As shown in Figs. 4 and 5, the moisture absorption and removal system 4 further comprises a second driving member 43 fixed on the moisture absorption and removal shell 41 and configured to drive the moisture absorption and removal member 42 to rotate. Figure 16 、 Figure 15 and Figure 20 As shown in Figs. 4 and 5, the moisture absorption and removal system 4 further comprises a second driving member 43 fixed on the moisture absorption and removal shell 41 and configured to drive the moisture absorption and removal member 42 to rotate.

[0203] In an optional embodiment, the rotation central axis of the moisture absorption and removal member 42 is parallel to the rotation central axis of the drum 2. The purpose of this arrangement is to facilitate the arrangement of structures in the equipment shell 1. Specifically, when the rotation central axis of the moisture absorption and removal member 42 is parallel to the rotation central axis of the drum 2, the portion of the main drying air duct 110 in which the first heat exchanger 32, the moisture absorption and removal system 4, and the second heat exchanger 34 are arranged is also parallel to the rotation central axis of the drum 2, i.e., the portion of the main drying air duct 110 in which the first heat exchanger 32, the moisture absorption and removal system 4, and the second heat exchanger 34 are arranged is arranged side by side with the drum 2 outside the drum 2. This achieves the maximum utilization of the space in the equipment shell 1 and facilitates the compactness and miniaturization of the overall structure of the laundry treatment equipment 200.

[0204] In an embodiment, as shown in Figs. 4 and 5, the second driving member 43 is arranged on the first shell 411. Figure 20 and Figure 20 In an embodiment, as shown in Figs. 4 and 5, the second driving member 43 is arranged on the first shell 411.

[0205] Alternatively, the second driving member 43 is arranged on the side surface of the first shell 411 away from the second shell 412. That is, the second driving member 43 is arranged between the moisture absorption and removal member 42 and the first heat exchanger 32. The purpose of this arrangement is that the air flowing from the first heat exchanger 32 to the second driving member 43 is low-temperature air, and the second driving member 43 is in a low-temperature and low-humidity environment, which facilitates the reduction of the influence of water vapor and high temperature on the second driving member 43 and ensures the service life of the second driving member 43.

[0206] Further, the second driving member 43 and the heating member 441 are located on the axial two sides of the moisture absorption and removal member 42, which facilitates the volume and space balance of the axial two sides of the moisture absorption and removal system 4, facilitates the general symmetry of the air flow on the two sides of the moisture absorption and removal 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 being located on the axial two sides of the moisture absorption and removal member 42 also facilitates the weight balance of the two sides of the moisture absorption and removal system 4.

[0207] 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 offset from the first opening 4110 in the axial direction of the moisture absorbing and removing member 42, please refer to Figure 20 As shown, the second driving member 43 is arranged to be not aligned with the central axis of rotation of the moisture absorbing and removing member 42, but offset from the first opening 4110 relative to the central axis of rotation, 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 to be 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, so as to improve the air speed and improve the drying efficiency.

[0208] Please refer to Figure 16 As shown, in one embodiment, the second driving member 43 includes a second motor 432. The second motor 432 is arranged to be offset from the first opening 4110 relative to the central axis of rotation of the moisture absorbing and removing member 42.

[0209] In an optional embodiment, the second motor 432 includes an eccentric motor, and the output shaft 4323 of the eccentric motor is connected coaxially with the moisture absorbing and removing member 42. In this way, the second driving member 43 is offset as a whole relative to the central axis of the moisture absorbing and removing member 42, but the output shaft 4323 of the second driving member 43 is aligned with the central 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 portion 4201, and improve the drying efficiency.

[0210] In another embodiment, the output shaft 4323 of the second driving member 43 is connected with the moisture absorbing and removing 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 absorbing and removing member 42 to the side away from the first opening 4110. The purpose of such arrangement is to further reduce the obstruction of the second driving member 43 to the first opening 4110, and the first opening 4110 can be arranged as close as possible to the central axis of the moisture absorbing and removing member 42, or even, the second driving member 43 can not obstruct the first opening 4110 at all.

[0211] Please refer to Figure 22As shown, in one embodiment, the output shaft 4323 of the second driving member 43 has a plurality of flat surfaces 43230 which are circumferentially symmetrically distributed. When the output shaft 4323 is connected with the moisture absorption and exhaust member 42 and drives the moisture absorption and exhaust 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 exhaust member 42, realize driving the moisture absorption and exhaust member 42 with a smaller diameter output shaft 4323, and reduce the abrasion and fatigue damage of the output shaft 4323 and the moisture absorption and exhaust member 42.

[0212] In addition to the output shaft 4323, please refer to Figure 20 As shown, the second motor 432 further includes a motor housing 4321, a rotating assembly (not shown) arranged in the motor housing 4321, an electric control part (not shown) arranged in the motor housing 4321 and connected with the rotating assembly, and the output shaft 4323 passes through the motor housing 4321 and is connected with the rotating assembly. The electric control part is located on one side of the rotating assembly and is used for connecting an external power supply and the rotating assembly. The motor housing 4321 is fixedly connected with the side end surface of the first housing 411 which is away from the second housing 412.

[0213] In one embodiment, please refer to Figure 20 As shown, the outer surface of the motor housing 4321 is a non-circular surface, and a protruding part 4322 is formed by outwardly protruding the electric control part. Based on the protruding part 4322, as Figure 20 、 Figure 20 As shown, the first housing 411 is provided with a limiting groove 4112 corresponding to the protruding part 4322, and the inner side wall of the limiting groove 4112 is used for abutting against the limiting part 4311 in the rotating direction of the moisture absorption and exhaust member 42 to limit the rotation of the limiting part 4311. That is, the limiting groove 4112 and the limiting wall are used for blocking 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 part 4322 in the circumferential direction.

[0214] In one embodiment, please continue to refer to Figure 16 As shown, the second driving member 43 further includes a sealing housing 431, and the motor housing 4321 of the second motor 432 is arranged in the sealing housing 431. The sealing housing 431 is sealingly connected with the side surface of the first housing 411 which is away from the second housing 412. By additionally arranging a sealing housing 431, the second motor 432 is integrally protected and sealed, which can further reduce the influence of water vapor in the main drying air duct 110 on the second driving member 43.

[0215] Specifically, as Figure 22As shown, the sealing shell 431 is provided with a plurality of second fixing lugs 4312, which are fixedly connected with the surface of the first shell 411 by fasteners (screws, bolts, etc.).

[0216] Optionally, as shown in Figure 18 , the second driving member 43 further comprises a sealing washer 434, which is arranged between the sealing shell 431 and the side surface of the first shell 411 away from the second shell 412 and surrounds the output shaft 4323. The sealing shell 431 is fixed on the first shell 411 by fasteners (screws, bolts, etc.). The sealing washer 434 is compressed between the sealing shell 431 and the first shell 411, so as to maintain the sealed connection between the sealing shell 431 and the first shell 411 and further reduce the possibility of water vapor entering the sealing shell 431.

[0217] Correspondingly, as shown in Figure 19 , the sealing shell 431 is outwardly convex to form 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.

[0218] As shown in Figure 18 and Figure 18 , the side end surface of the first shell 411 away from the second shell 412 is axially recessed to form a motor mounting groove 4111 facing the second shell 412, and a part of the sealing shell 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 sealing shell 431, which is beneficial to the overall quick 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.

[0219] Next, please refer to Figure 18 and Figure 18 for the introduction of the moisture absorbing and discharging member 42 of the embodiment of the present application.

[0220] As shown in Figure 18As 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.

[0221] 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.

[0222] 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.

[0223] 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.

[0224] 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.

[0225] 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 fix and 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.

[0226] As shown in Figure 18 , the inner fixing part 4241 is provided with a connecting hole 42410 penetrating along 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 matched 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 matched in concave-convex to form circumferential fixing connection.

[0227] 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 includes 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 includes the first plate body 4231 and further includes a second plate body 4232 connected with the first plate body 4231, the second plate body 4232 is used to abut the edge of the axial end surface of the moisture absorbing and releasing medium layer 421 facing the first heat exchanger 32, the support part 424 includes 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.

[0228] 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 includes a support outer ring 4243 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 .

[0229] 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.

[0230] 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.

[0231] As shown in Figure 18 , the inner fixed part 4241 is provided with a second sunken groove 42413. 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.

[0232] 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.

[0233] 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.

[0234] 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.

[0235] As shown in 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 drainage 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 drainage medium layer 421. The first abutting portion 4272 and the second abutting portion 4274 abut the axial sides of the moisture absorption and drainage medium layer 421 with a large area, and exert a certain compression force on the moisture absorption and drainage medium layer 421.

[0236] 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.

[0237] In one embodiment, referring to Figure 19 , the moisture absorption and drainage member 42 further comprises a second fixing support 425, which is arranged on the side of the moisture absorption and drainage shell 41 facing the second shell 412, and the second fixing support 425 is fixedly connected with the first fixing support 422. The second fixing support 425 is used to abut at least part of the outer circumferential surface of the moisture absorption and drainage medium layer 421 and the side end surface away from the first shell 411.

[0238] In this way, the first fixing support 422 and the second fixing support 425 can abut and compress the two axial end surfaces of the moisture absorption and drainage medium layer 421, and protect the outer circumferential surface of the moisture absorption and drainage medium layer 421.

[0239] Specifically, referring to ​ and ​ , the second fixing support 425 comprises a third plate body 4251 and a fourth plate body 4252 connected with each other. The third plate body 4251 abuts at least part of the outer circumferential surface of the moisture absorption and drainage medium layer 421, and the fourth plate body 4252 abuts the edge of the axial end surface of the moisture absorption and drainage medium layer 421 facing the second shell 412.

[0240] The first plate body 4231 and the third plate body 4251 are arranged in a stacked manner in the radial direction, that is, the first plate body 4231 and the third plate body 4251 are in a sleeved relationship. The third plate body 4251 can be sleeved with the first plate body 4231, or the first plate body 4231 can be sleeved with the third plate body 4251. As shown in ​ and ​As shown, the two circumferential surfaces of the third plate body 4251 and the first plate body 4231 close to each other are fixedly connected through the buckling structure 426. For example, one of the two circumferential surfaces of the third plate body 4251 and the first plate body 4231 close to each other is provided with a buckling protrusion 4262, and the other is provided with a buckling groove 4261. Through the cooperation of the buckling protrusion 4262 and the buckling groove 4261, the quick connection of the first fixed ring 423 and the second fixed support 425 is realized, and the radial area occupied is not too large, which is beneficial to reduce the outer diameter of the moisture absorption and exhaust element 42.
