Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a drying module and clothing processing equipment. Background Technology

[0002] Currently, clothes drying equipment with drying function is mainly divided into two types: one is the direct exhaust type, which raises the temperature of the air inside the drum through a heating device. The hot air carries away the moisture in the clothes, forming humid air, which is then directly discharged to the outside environment through an exhaust pipe. The other type is the heat pump type, which delivers high-temperature, low-humidity hot air into the drum to evaporate the moisture in the clothes and reduce their moisture content. The humid air discharged after passing through the drum is first cooled and condensed, then heated up and sent back into the drum.

[0003] The disadvantages of the above technologies are low drying efficiency, slow drying speed, and high energy consumption.

[0004] In view of this, a clothing processing device with low energy consumption and high drying efficiency is proposed. Summary of the Invention

[0084] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0085] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly or indirectly fixed to or set on that other component. When a component is referred to as being "connected to" another component, it can be directly or indirectly connected to that other component. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. "A plurality of" means two or more, unless otherwise expressly and specifically defined.

[0086] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0087] Please see Figures 1 to 4 As shown in the figure, this application provides a garment processing device 200.

[0088] Based on the normal working state of the clothing processing device 200, for ease of description and understanding, we first define multiple directions such as "up", "down", "left", "right", "front" and "back". The side of the clothing processing device 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 user's left hand is "left", and the side corresponding to the user's right hand is "right".

[0089] like Figures 1 to 4 As shown, the garment processing equipment 200 includes a housing 1, a drying module 100, a first drive member 5, and a drum 2 disposed within the housing 1. The first drive member 5 is connected to the drum 2 and is used to drive the drum 2 to rotate.

[0090] like Figure 2 , Figure 3 and Figure 4 As shown, the equipment housing 1 may include a plurality of outer panels 15 that are mutually enclosing and connected to the drying module 100. For example, the plurality of outer panels 15 of the equipment housing 1 may include an upper side panel (or upper cover), a front side panel (or door panel), a left side panel, a right side panel, and a rear side panel, etc. In other embodiments, the plurality of outer panels 15 may have other numbers and be connected in other orientations.

[0091] Please refer to the following: Figure 2 , Figure 3 and Figure 4 ,as well as Figure 8 As shown, the roller 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 clothing processing space 22.

[0092] Reference Figure 2 and Figure 3 As shown, the equipment housing 1 may further include a first support member 16 and a second support member (not shown). The first support member 16 is disposed between the front side plate and the roller 2, and the second support member (not shown) is disposed between the rear side plate and the roller 2. The axial ends of the roller 2 are rotatably mounted between the first support member 16 and the second support member. In some embodiments, the second support member may be integrally disposed with the rear side plate.

[0093] In one embodiment, the air inlet 21 of the roller 2 may be positioned forward, that is, towards the first support member 16.

[0094] like Figure 5 and Figure 6 As shown, the drying module 100 may include a base assembly 11 located below the roller 2, and a plurality of outer uprights 15 are connected to the periphery of the base assembly 11 to enclose the roller 2 within it.

[0095] Reference Figure 5 , Figure 6 and Figure 7 As shown, in one embodiment, the drying module 100 of the clothing processing equipment 200 may further include a heat pump system 3 and a moisture absorption and dehumidification system 4. The heat pump system 3 is used to provide at least one cold source and at least one heat source to perform primary condensation dehumidification and heating on the air flowing out of the drum 2, and the moisture absorption and dehumidification system 4 is used to perform primary moisture absorption and dehumidification (secondary dehumidification) on the air flowing out of the drum 2.

[0096] Please see Figure 6 As shown, the heat pump system 3 includes a compressor 31, a second heat exchanger 34, a throttling device 36, and a first heat exchanger 32 connected in sequence along the refrigerant flow direction.

[0097] The refrigerants mentioned include hydrofluorocarbons (HFCs), chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), or natural refrigerants (such as ammonia, carbon dioxide, hydrocarbons, etc.). The second heat exchanger 34 acts as a heat source to heat the air, allowing the high-temperature air to enter the drum 2. The first heat exchanger 32 acts as a cold source to cool and condense the air flowing out of the drum 2.

[0098] In one embodiment, such as Figure 6 and Figure 7 As shown, a main drying air duct 110 is defined within the base assembly 11, and a receiving cavity 112, isolated from the main drying air duct 110, is also defined on the base assembly 11. The air inlet of the main drying air duct 110 is connected to the air outlet 23 of the drum 2, and the air outlet of the main drying air duct 110 is connected to the air inlet 21 of the drum 2. Please refer to... Figure 6 and Figure 7 As shown, in the heat pump system 3, the first heat exchanger 32 and the second heat exchanger 34 are arranged in the main drying air duct 110 along the wind direction, and the compressor 31 and the throttling device 36 are arranged in the receiving cavity 112 of the base assembly 11.

[0099] In addition, please see Figure 5 As shown, components that do not participate in air circulation, such as the first drive component 5, are also located in the accommodating cavity 112.

[0100] After passing through the first heat exchanger 32, the air temperature decreases, the absolute humidity decreases, and the relative humidity increases. After passing through the second heat exchanger 34, the air temperature increases, and the relative humidity decreases.

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

[0102] Absolute humidity refers to the mass of water vapor contained in a unit volume of air, and it directly reflects the actual content of water vapor in the air.

[0103] 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.

[0104] 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.

[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 from the clothes.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] In some embodiments, the moisture-absorbing and desiccant component 42 is disposed within the moisture-absorbing and desiccant housing 41, as long as it can perform the function of moisture absorption and desiccant. The shape of the moisture-absorbing and desiccant component 42 is not limited; it can be a triangle, a square, or other polygons, or it can be a disc shape, such as... Figure 16 and Figure 18 As shown, the disc-shaped moisture-absorbing and dehumidifying component 42 is designed to circulate between the moisture-absorbing zone 4102 and the desorption zone 4101. The part of the moisture-absorbing and dehumidifying component 42 (i.e., the moisture-absorbing part 4201) that moves to the moisture-absorbing zone 4102 absorbs moisture from the air. Then, the part of the moisture-absorbing and dehumidifying component 42 that has absorbed moisture moves to the desorption zone 4101 to desorb the moisture. After desorption, the part of the moisture-absorbing and dehumidifying component 42 (i.e., the desorption part 4202) moves back to the moisture-absorbing zone 4102 to absorb moisture. This cycle is repeated to remove moisture from the air, thereby achieving the effect of moisture absorption and dehumidification.

[0111] In some embodiments, the moisture absorption and dehumidification component 42 is a dehumidification turntable component. The dehumidification turntable component can be a honeycomb or corrugated turntable carrying a desiccant, which can adsorb and desorb absorbed water vapor to achieve repeated desorption and regeneration. In some embodiments, the dehumidification turntable includes an inorganic / organic fiber carrier, such as ceramics, glass fibers, MOFs (Metal-Organic Frameworks), COFs (Covalent-Organic Frameworks), cordierite, etc. The fiber carrier is coated with a desiccant such as a molecular sieve, and the desiccant is evenly distributed between the fiber carriers and on the surface of the fiber carrier to achieve the adsorption of moisture in the airflow. Hygroscopic agents can be materials with hygroscopic properties such as zeolite, modified / synthetic zeolite, molecular sieves (including but not limited to single crystal molecular sieves or mixed crystal molecular sieves such as type A molecular sieve, type X / Y molecular sieve, ZSM molecular sieve, Beta molecular sieve, etc.), polymeric hygroscopic agents, alkali metal aluminosilicates (13X molecular sieve), lithium chloride, silica gel, modified silica gel, activated alumina, etc.

[0112] In one optional embodiment, the moisture absorption and dehumidification component 42 is a molecular sieve dehumidification disc.

[0113] In one embodiment, the regeneration component 44 is a heating element used to heat the air in the desorption zone 4101. In another embodiment, the regeneration component 44 includes an electric heating element.

[0114] Then, please refer to the following: Figure 6 , Figure 7 and Figure 8 As shown, in one embodiment, the heat pump system 3 further includes a third heat exchanger 33, which is connected in series between the throttling device 36 and the first heat exchanger 32, or between the first heat exchanger 32 and the compressor 31. The third heat exchanger 33 serves as another cold source, used to cool, condense, and dehumidify the high-temperature air after the desorption section 4202, thereby reducing the absolute humidity of the air after the desorption section 4202.

[0115] By using a third heat exchanger 33 as the cold source for the moisture absorption and dehumidification system 4, the internal circulation of heat during the regeneration process of the moisture absorption and dehumidification system 4 can be further realized, preventing high-temperature air from being discharged outside the equipment housing 1. This makes the clothing processing equipment 200 more widely applicable.

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

[0117] 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. (See also...) Figure 6 and Figure 7 As shown. 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 may be connected sequentially 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 may be connected in parallel with the first heat exchanger 32 downstream of the throttling device 36; or, the throttling device 36 may include two parallel throttling elements, one connected in series with the first heat exchanger 32 and the other connected in series with the third heat exchanger 33, with the first heat exchanger 32 and the third heat exchanger 33 connected in parallel.

[0119] Please see Figure 6As shown, the base assembly 11 is also provided with a regeneration air duct. The regeneration air duct is formed by connecting at least the desorption zone 4101 in the moisture absorption and desorption housing 41 and the first air duct section 1111. The regeneration air duct is used to accommodate the desorption section 4202 of the moisture absorption and desorption component 42 and the third heat exchanger 33. The regeneration air duct and the main drying air duct 110 are functionally independent and structurally isolated from each other.

[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 see Figure 5 , Figure 6 , Figure 11 and Figure 12 As shown, the base assembly 11 includes a base 12 and a top cover 13, as... Figure 5 and Figure 6 As shown, the base 12 includes a base plate 120 and a first side plate 121 disposed on the upper surface of the base plate 120. The upper cover 13 is connected to the end face of the first side plate 121 that is away from the base plate 120, that is, the upper end face of the first side plate 121, so as to define the main drying air duct 110 mentioned above.

[0122] In one alternative embodiment, such as Figure 7 and Figure 16 As shown, at least a portion of the moisture-absorbing and desiccant housing 41 and the moisture-absorbing and desiccant component 42 are disposed within the main drying air duct 110, and the rotation center axis of the moisture-absorbing and desiccant component 42 is parallel to the airflow direction within the main drying air duct 110. It can be understood that here, the rotation center axis of the moisture-absorbing and desiccant component 42 is not parallel to the airflow direction at any arbitrary location within the main drying air duct 110, but rather parallel to the airflow direction of the portion within the main drying air duct 110 where at least the moisture-absorbing and desiccant component 42 is disposed. That is, the air passing through the moisture-absorbing and desiccant component 42 flows in a straight line within the main drying air duct 110.

[0123] The purpose of this design is to ensure that the air flows straight within the main drying duct 110, at least in the section with the moisture absorption and desiccation components 42, reducing the possibility of air reversal and eddy current generation. This results in high airflow efficiency and low wind resistance for the drying module 100. No complex isolation and sealing structure is required between the main drying duct 110 and the moisture absorption and desiccation system 4. This garment processing equipment 200 also has the advantages of fast drying speed and low energy consumption.

[0124] Please see Figure 5 and Figure 6 As shown, in one embodiment, the base 12 further includes a second side plate 122 disposed on the upper surface of the base plate 120 and located beside the first side plate 121. The upper cover 13 is also connected to the upper end face of the second side plate 122 to define a first air duct portion 1111 of the regeneration air duct.

[0125] In one embodiment, a second air duct section is provided within the moisture absorption and desiccation housing 41 disposed within the main drying air duct 110. The first air duct section 1111 communicates with the second air duct section and forms a regeneration air duct. A second heat exchanger 34 is disposed within the first air duct section 1111.

[0126] It is understandable that, for the base assembly 11, there is no need to set up a clear dividing structure in the main drying air duct 110 to divide the part used to accommodate the moisture absorption and desiccation shell 41. Instead, the moisture absorption and desiccation shell 41 itself in the main drying air duct 110 defines another part of the regeneration air duct, namely the desorption zone 4101.

[0127] The first heat exchanger 32 and the second heat exchanger 34 are disposed within the main drying air duct 110, that is, on the upper surface of the base plate 120. Condensate is generated around the first heat exchanger 32. Therefore, in one embodiment, please refer to... Figure 11 and Figure 12 As shown, the base plate 120 is provided with a water channel 113 located in the main drying air duct 110. In other words, condensate will drip onto the upper surface of the base plate 120, and the lower part of the space of the main drying air duct 110 can serve as the water channel 113.

[0128] like Figure 5 , Figure 6 and Figure 11 As shown, the base plate 120 includes a water collection box 123 located outside the first side plate 121. A first drain outlet 1210 is provided on the first side plate 121 and / or the base plate 120, and the first drain outlet 1210 connects the water collection box 123 to the water passage 113. Furthermore, as... Figure 11 As shown, the bottom surface of the water channel 113 (that is, the upper surface of the bottom plate 120 located inside the main drying air duct 110) gradually slopes down in the direction toward the first drain outlet 1210. This facilitates the automatic flow of condensate toward the first drain outlet 1210 and into the water collection box 123.

[0129] The water collection box 123 can be configured as a drawer-type, screw-type, or other detachable water collection structure, or it can be drained into the sewer through a water pipe.

[0130] like Figure 12As shown, the third heat exchanger 33 within the first air duct section 1111 also generates condensate. This condensate drips onto the upper surface of the base plate 120 located within the first air duct section 1111. In other words, the lower portion of the space within the first air duct section 1111 also serves as a water channel 113. A second drain outlet 1220 is provided on the second side plate 122 and / or the base plate 120. Within the first air duct section 1111, the upper surface of the base plate 120 gradually decreases towards the second drain outlet 1220, which communicates with the water collection box 123. In an optional embodiment, depending on the positional relationship between the first air duct section 1111 and the main drying air duct 110, the first drain outlet 1210 can be sequentially connected to the main drying air duct 110 and the first drain outlet 1210.

[0131] Please see Figure 6 , Figure 11 and Figure 12 As shown, in one embodiment, the base assembly 11 further includes an isolation plate 14, which is disposed within the main drying air duct 110. The isolation plate 14 is spaced apart from the upper surface of the base plate 120, forming a water passage 113. At least one drainage hole 141 is provided on the isolation plate 14 corresponding to the position of the first heat exchanger 32. Thus, the first heat exchanger 32 and the second heat exchanger 34 can be supported on the isolation plate 14, and the condensate generated on the first heat exchanger 32 can enter the water passage 113 through the drainage hole 141.

[0132] like Figure 6 , Figure 11 and Figure 12 As shown, in one embodiment, a plurality of raising blocks 124 protrude from the upper surface of the base plate 120. The raising blocks 124 are used to support the partition plate 14 at a certain height, that is, the partition plate 14 is located on the end face of the raising block 124 facing the upper cover 13. In order to evenly support the multiple positions of the partition plate 14, the raising blocks 124 are designed with different shapes and positions. For example, referring to… Figure 6 As shown, a portion of the raised blocks 124 (first raised blocks 1241) are disposed on the inner peripheral wall of the first side plate 121 to support the edge of the isolation plate 14, and another portion of the raised blocks 124 (multiple second raised blocks 1242) are disposed at intervals in the water channel 113 and the main drying air duct 110 to provide multi-point support for the middle part of the isolation plate 14.

[0133] like Figure 11 and Figure 12As shown, in one embodiment, a portion of the raised blocks 124 (the third raised block 1243) surround and define a first mounting cavity 1240 within the water channel 113. The first mounting cavity 1240 is configured to accommodate a part of the moisture absorption and desiccation system 4, specifically, a part of the moisture absorption and desiccation housing 41. The isolation plate 14 has a clearance opening 143 corresponding to the first mounting cavity 1240. Figure 6 As shown. Thus, the moisture absorption and dehumidification system 4 can be located partly above the partition plate 14 and partly below the partition plate 14, and is isolated from the water channel 113. The purpose of this arrangement is to allow the moisture absorption and dehumidification system 4 to be as close as possible to the bottom plate 120 in the vertical direction, thereby lowering the position of the moisture absorption and dehumidification system 4 and consequently reducing the overall height of the garment processing equipment 200.

[0134] In one optional embodiment, where permissible, the lower surface of the base plate 120 may protrude downwards corresponding to the first mounting cavity 1240, and the upper surface of the base plate 120 may be recessed downwards corresponding to the first mounting cavity 1240, such as... Figure 11 and Figure 12 As shown, the position of the moisture absorption and dehumidification system 4 is further reduced.

[0135] Please see Figure 11 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.

[0136] Furthermore, condensate will also be generated around the first heat exchanger 32. Therefore, in one embodiment, please refer to... Figure 6 and Figure 11 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 6 As shown.

[0137] Please see Figure 6 and Figure 12 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.

[0138] 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.

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

[0140] In other embodiments, other shims 124 may also be connected to the isolation plate 14 via fasteners and / or limiting fit structures. For example, the third shim 1243 may be connected to the isolation plate 14 via fasteners, and the second shim 1242 may be connected to the isolation plate 14 via a limiting fit structure.

[0141] Please see Figure 13 As shown, in one embodiment, the upper surfaces of the first side plate 121 and the second side plate 122 are connected to the lower 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 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 surface of the upper cover 13 is provided with the other of the sealing groove 1312 and the sealing protrusion 1311, with the sealing protrusion 1311 located within the sealing groove 1312. In an optional embodiment, a sealing element (not shown), such as an elastic sealing strip, is provided between the sealing protrusion 1311 and the sealing groove 1312.

[0142] Furthermore, 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 and bolts) to keep the seal pressed between the sealing groove 1312 and the sealing protrusion 1311, ensuring the sealing performance 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 methods.

[0143] like Figure 6 As shown, the second side plate 122 is connected to a portion of the first side plate 121, or in other words, a portion of the first side plate 121 is used to enclose and define the first air duct portion 1111 with the second side plate 122. Figure 6 and Figure 7 As shown, the first side plate 121 is provided with a first connecting port 1211 and a second connecting port 1212. The first connecting port 1211 connects the main drying air duct 110 and the first air duct section 1111. The second side plate 122 is provided with a third connecting port 1221. Both the second connecting port 1212 and the third connecting port 1221 are connected to the accommodating cavity 112. The first connecting port 1211 is used to connect the first heat exchanger 32 with the desorption zone 4101 of the moisture absorption and desorption housing 41 along the airflow direction. The second connecting port 1212 and the third connecting port 1221 are used to connect the first heat exchanger 32 with the regeneration assembly 44 along the airflow direction.

[0144] Please refer to the following: Figure 4 As shown, the first driving component 5 is used to drive the roller 2 to rotate. The first driving component 5 may specifically include a first motor, a synchronous pulley, and a first synchronous belt (not shown). The first motor drives the synchronous pulley to rotate, the synchronous pulley drives the synchronous belt to rotate, and the synchronous belt is sleeved on the outer circumferential surface of the roller 2 to drive the roller 2 to rotate synchronously.

[0145] In one embodiment, the first driving member 5 may include a second synchronous belt, a connecting arm, and a tensioning member (none shown). The connecting arm is movably mounted on the first motor and connected to the synchronous pulley. The second synchronous belt is connected between the synchronous pulley and the drive shaft of the first motor. One end of the tensioning member is connected to the synchronous pulley, and the other end is connected to the base plate 120 to tension at least the second synchronous belt. The tensioning member may specifically be a spring, a tension rope, etc.

[0146] like Figure 8 As shown, in one embodiment, a mounting portion 127 is provided on the base plate 120, and a chamfered arc surface 1270 is provided on the protrusion inside the mounting portion 127 on the base plate 120. Typically, based on the positional relationship between the tensioning member and the synchronous wheel, the tensioning member is inclined relative to the vertical and horizontal directions. The chamfered arc surface 1270 is used to avoid the tensioning member and prevent the right-angled surface from interfering with the elastic expansion and contraction of the tensioning member.

[0147] The rear side of base 12 is used for connection with the rear side panel. For example... Figure 9 As shown, in one embodiment, the edge of the base plate 120 is provided with a plurality of guide blocks 126. The guide blocks 126 are located on the periphery of the first side plate 121. The side of the guide block 126 facing the first side plate 121 has a guide surface 1260, which is inclined close to the first side plate 121 in the direction from the top cover 13 to the base plate 120. Thus, when the rear side plate is installed, the rear side plate is aligned with the guide block 126 and the rear side plate is 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, realizing quick positioning and pre-fixed connection between the rear side plate and the base 12.

[0148] Please see Figure 6 , Figure 7 and Figure 11 As shown, in one embodiment, the base 12 further includes a third side plate 125 disposed on the base plate 120 and located outside the first side plate 121 and the second side plate 122, the third side plate 125 enclosing and defining the front air duct 1250; as Figure 11 As shown, the third side plate 125 is provided with a fourth connecting port 1251 that is connected to the main drying air duct 110. The end face of the third side plate 125 away from the bottom plate 120 defines a fifth connecting port 1252. The second connecting port 1212 is used to connect with the air outlet 23 of the drum 2.

[0149] In one embodiment, please refer to [reference needed]. Figure 2 and Figure 3 As shown, the first support member 16 has a third opening 161 corresponding to the air inlet 21 of the roller 2. The third opening 161 is connected to and aligned with the air inlet 21 in the axial direction of the roller 2. During the rotation of the roller 2, the air inlet 21 remains connected to the third opening 161. The third opening 161 is also connected to the front air duct 1250, so that the clothing processing space 22 of the roller 2 is connected to the front air duct 1250.

[0150] Please refer to the details. Figure 2 and Figure 3 As shown, a filter duct 160 is formed on the inner peripheral wall of the third opening 161 on the first support member 16, and the filter duct 160 connects the front air duct 1250 and the third opening 161. This achieves communication between the third opening 161 and the front air duct 1250. Optionally, a filter device (not shown) may be provided in the filter duct 160 to filter lint and other debris carried by the air flowing out of the roller 2. Optionally, a filter device may also be provided in the front air duct 1250. The filter device includes, but is not limited to, filter boxes, filter plates, etc.

[0151] Reference Figure 2 and Figure 3 As shown, the first support member 16 is located above the third side plate 125. The filter duct 160 and the front duct 1250 are generally aligned and connected in the vertical direction.

[0152] Please see Figure 6 and Figure 12 As shown, in one embodiment, the upper cover 13 is provided with a first cable routing hole 132. The first cable routing hole 132 is used for power lines, signal lines, etc. to pass through. In some embodiments, the regeneration assembly 44 includes a heating element 441; please refer to the relevant documentation. Figure 16 and Figure 17 As shown, heating element 441 is specifically an electric heating element. In this case, the power supply line is used to provide power to the electric heating element.

[0153] like Figure 6 and Figure 12 As shown, the edge of the upper cover 13 is provided with a plurality of spaced wire fixing blocks 133. The wire fixing blocks 133 are used to fix power lines, signal lines, etc. that pass through the first wire hole 132. The form of the wire fixing blocks 133 is not limited.

[0154] Please see Figure 4 As shown, in one embodiment, the clothing processing device 200 further includes a main circulation fan 6, which is at least partially disposed in the main drying duct 110. The first driving member 5 is connected to the main circulation fan 6 to drive the main circulation fan 6 to rotate. The main circulation fan 6 is used to drive the airflow in the main drying duct 110.

[0155] In one embodiment, such as Figure 4 As shown, the main circulating fan 6 is located downstream of the second heat exchanger 34 and is used to transport the air from the main drying air duct 110 to the air inlet 21 of the drum 2.

[0156] In one embodiment, the first drive element 5 is a dual drive element, such as a dual-rotor motor, having a first drive shaft and a second drive shaft (not shown). The second drive shaft is used to drive the roller 2, and the first drive shaft is used to connect to the main circulating fan 6. In this way, a single first drive element 5 can be used to operate both the roller 2 and the main circulating fan 6, saving structural costs and reducing volume.

[0157] Please continue reading. Figure 6 and Figure 12As shown, the main circulating fan 6 is disposed between the upper cover 13 and the first side plate 121. The upper cover 13 and / or the first side plate 121 are provided with mounting positions 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 accommodate the shape of the main circulating fan 6 and to minimize the height of the base assembly 11 at least corresponding to the position of the main circulating fan 6, in one embodiment, the upper cover 13 is provided with one or more reinforcing ribs 134 on the upper surface corresponding to the main circulating fan 6, so as to make the upper cover 13 as thin as possible while ensuring the strength of the upper cover 13.

[0158] In one embodiment, any one of the base 12, the partition plate 14, and the top cover 13 may be a plastic component, for example, an integral structure formed by injection molding. Furthermore, the plastic components of the base 12, partition plate 14, and top cover 13 also have low thermal conductivity, resulting in lower heat exchange with the air in the main drying duct 110 and the regeneration duct.

[0159] Next, please refer to Figure 6 , Figure 7 and Figure 10 As shown, in the heat pump system 3, the compressor 31, the second heat exchanger 34, the throttle valve, the third heat exchanger 33 and the first heat exchanger 32 are all connected in sequence through refrigerant pipes 35.

[0160] During operation, compressor 31 continuously draws in and discharges refrigerant, thus causing vibration. Generally, this vibration manifests as multi-directional vibration within the horizontal plane. To reduce the pulling and squeezing of the refrigerant piping 35 during compressor 31 vibration and to prevent breakage of the refrigerant piping 35, especially the portion of the refrigerant piping 35 closest to compressor 31, [further measures are needed]. Figure 10 As shown, in one embodiment, the refrigerant pipe fitting 35 includes multiple pipe segments 351, with adjacent pipe segments 351 bent relative to each other in the horizontal and / or vertical directions. For example, when the compressor 31 vibrates in the left-right direction, and the first pipe segment 351 connected to the compressor 31 also extends in the left-right direction, the first pipe segment 351 will experience a movement in the left-right direction, and the second pipe segment 351 will deflect and bend in the left-right direction. For sequentially connected and slender (length greater than outer diameter) pipe segments 351, the risk of breakage caused by deflection and bending is significantly reduced compared to tension and compression along the length direction. When multiple pipe segments 351 are sequentially bent and connected, the tension and compression of the refrigerant pipe fitting 35 caused by the vibration of the compressor 31 will be significantly improved.

[0161] The horizontal bending connection of adjacent pipe segments 351 means that the projections of adjacent pipe segments 351 on the horizontal plane or on the base plate 120 are bent; the vertical bending connection of adjacent pipe segments 351 means that the projections of adjacent pipe segments 351 in the vertical plane are bent.

[0162] In one embodiment, the refrigerant fitting 35 is a copper tube. Copper tubes have good ductility, making it easy to manufacture multiple relatively bent tube segments 351. Further optionally, adjacent tube segments 351 are smoothly connected to reduce the resistance to refrigerant flow between tube segments 351 and to facilitate the assembly operation of the garment handling equipment 200.

[0163] Please see Figure 6 and Figure 8 As shown, in one embodiment, the compressor 31's outer casing is provided with multiple first fixing ears 311, each first fixing ear 311 having a fixing hole 3110. A first fastener 37 is disposed within the fixing hole 3110 and connected to the base plate 120, the outer diameter of the first fastener 37 being smaller than the inner diameter of the fixing hole 3110. Thus, an annular gap is formed around the first fastener 37. This arrangement is intended to accommodate the vibration of the compressor 31. If the first fixing ears 311 and the first fastener 37 are fixedly connected without gap, the continuous vibration of the compressor 31 may cause damage to the first fixing ears 311, or even damage to the outer casing of the compressor 31, and may also cause the base plate 120, along with the entire base 12 and base assembly 11, to vibrate. In this embodiment, the vibration of the compressor 31 is transmitted to the refrigerant pipe 35, and buffered and consumed by the bent pipe section 351, reducing damage to the compressor 31 itself and also mitigating the overall vibration of the clothing processing equipment 200.

[0164] In one alternative embodiment, please refer to Figure 10 As shown, in the heat pump system 3, multiple sequentially connected pipe segments 351 define a clearance space 350, which is used to accommodate the first driving member 5. This arrangement is intended so that, since both the refrigerant pipe 35 and the first driving member 5 are located within the receiving cavity 112 of the base plate 120, the refrigerant pipe 35 must avoid the first driving member 5. Optionally, at least a portion of the refrigerant pipe 35 is located below the first driving member 5 to avoid affecting the connection between the first driving member 5 and the roller 2. Therefore, the clearance space 350 is defined by the portion of pipe segment 351 located below the first driving member 5 and the portion of pipe segment 351 located around the first driving member 5 adapted to the shape of the first driving member 5.

[0165] Next, we will introduce the moisture absorption and dehumidification system 4 of this application embodiment.

[0166] Please see Figure 15 , Figure 16 , Figure 17 and Figure 22 As shown, in one embodiment, in the moisture absorption and desiccation system 4, the moisture absorption and desiccation housing 41 is provided with a first opening 4110, such as... Figure 14 , Figure 16 and Figure 22 As shown, the moisture-absorbing and desiccant housing 41 is also provided with a second opening 4120. The first opening 4110 and the second opening 4120 respectively expose a portion of the surface of the moisture-absorbing and desiccant component 42, so that the first opening 4110 and the second opening 4120 are connected through the moisture-absorbing part 4201 of the moisture-absorbing and desiccant component 42. Air passes through the passage formed by the first opening 4110, the moisture-absorbing part 4201 and the second opening 4120 in sequence, and the moisture therein can be absorbed by the moisture-absorbing part 4201. The part inside the moisture-absorbing and desiccant housing 41 corresponding to the first opening 4110 and the second opening 4120 is called the moisture-absorbing area 4102.

[0167] In one alternative embodiment, please refer to Figure 14 , Figure 16 and Figure 22 As shown, the first opening 4110 is formed on the first axial end face of the moisture-absorbing and desiccant housing 41, and the first opening 4110 exposes a portion of the first axial end face of the moisture-absorbing and desiccant component 42. This allows the first opening 4110 to be manufactured in a simple form and has a larger area, which facilitates increasing the air passage area of ​​the moisture-absorbing part 4201 and improving the adsorption efficiency of moisture in the moisture-absorbing part 4201.

[0168] In one alternative embodiment, please refer to Figure 15 , Figure 16 , Figure 17 and Figure 22 As shown, the second opening 4120 is formed on the second axial end face of the moisture-absorbing and desiccant housing 41, and the second opening 4120 exposes a portion of the second axial end face of the moisture-absorbing and desiccant member 42. Similarly, this allows the second opening 4120 to be made in a simple form and has a larger area, which facilitates increasing the air passage area of ​​the moisture-absorbing part 4201 and improving the adsorption efficiency of moisture in the moisture-absorbing part 4201.

[0169] In one alternative embodiment, please refer to Figure 16 , Figure 21 and Figure 22 As shown, the first opening 4110 is formed on the first axial end face of the moisture-absorbing and desiccant housing 41, and the second opening 4120 is formed on the second axial end face of the moisture-absorbing and desiccant housing 41. Overall, the moisture-absorbing and desiccant housing 41 and the moisture-absorbing and desiccant component 42 have a larger air passage area, which is beneficial to improving the moisture adsorption efficiency, reducing the consumption of air kinetic energy, reducing energy consumption, and improving drying efficiency.

[0170] Further optional, please refer to Figure 16 , Figure 17 and Figure 22 As shown, the first opening 4110 and the second opening 4120 are connected axially via the moisture-absorbing portion 4201 of the moisture-absorbing and desiccant 42. Thus, the first opening 4110 and the second opening 4120 are aligned and connected along the axial direction of the moisture-absorbing and desiccant 42. Air passes axially through the moisture-absorbing and desiccant 42, which has a larger airflow area, an adsorption area, and lower air resistance. This facilitates increased airflow velocity within the moisture-absorbing and desiccant system 4, thereby improving moisture desorption efficiency and reducing energy consumption.

[0171] In one embodiment, both the first and second axial end faces of the moisture-absorbing and wicking member 42 are circular. Both the first opening 4110 and the second opening 4120 are fan-shaped. Optionally, the areas of both the first opening 4110 and the second opening 4120 are at least 50% of the area of ​​the axial end face of the moisture-absorbing and wicking member 42. More preferably, the areas of both the first opening 4110 and the second opening 4120 are at least 60% of the area of ​​the axial end face of the moisture-absorbing and wicking member 42. More preferably, the areas of both the first opening 4110 and the second opening 4120 are at least 70% of the area of ​​the axial end face of the moisture-absorbing and wicking member 42. More preferably, the areas of both the first opening 4110 and the second opening 4120 are at least 80% of the area of ​​the axial end face of the moisture-absorbing and wicking member 42. This ensures that both the first opening 4110 and the second opening 4120 have sufficient area, while allowing for a smaller diameter and volume in the design of the moisture-absorbing and wicking member 42, which helps to reduce the overall volume of the moisture-absorbing and wicking system 4 and the overall volume of the clothing treatment device 200.

[0172] Please refer to the following: Figure 7 As shown, in one embodiment, the first heat exchanger 32, the moisture absorption and dehumidification system 4, and the second heat exchanger 34 are arranged sequentially along the axial direction of the moisture absorption and dehumidification component 42 within the main drying air duct 110. Figure 7The solid triangular arrows in the diagram indicate the airflow direction. Within the main drying duct 110, the portion containing at least the first heat exchanger 32, the moisture absorption and desiccation system 4, and the second heat exchanger 34 is generally square. This allows air to pass through the first heat exchanger 32, the moisture absorption and desiccation system 4, and the second heat exchanger 34 in a straight line, avoiding air reversal and eddies, ensuring the highest airflow efficiency between these components. Furthermore, within the moisture absorption and desiccation component 42, the airflow direction is completely parallel to the direction of its vents. Air dried by the moisture absorption and desiccation component 42 can exit directly, minimizing the loss of air kinetic energy and wind speed. Depending on specific needs, within the main drying duct 110, the first heat exchanger 32, the moisture absorption and desiccation system 4, and the second heat exchanger 34 can be arranged sequentially at intervals along the axial direction of the moisture absorption and desiccation component 42, or they can be arranged without intervals, as long as it does not affect their respective operation.

[0173] Please see Figure 16 , Figure 17 , Figure 21 and Figure 22 As shown, the moisture-absorbing and desiccant housing 41 includes a first housing 411 and a second housing 412. The first housing 411 and the second housing 412 are connected opposite each other on both axial sides of the moisture-absorbing and desiccant member 42 to confine the moisture-absorbing and desiccant member 42 within it. A first opening 4110 is provided on the first housing 411, and a second opening 4120 is provided on the second housing 412. The first housing 411 and the second housing 412 can be connected by fasteners (such as bolts, screws, etc.). Furthermore, please refer to [reference needed]. Figure 16 and Figure 17 As shown, in one optional embodiment, depending on the shape of the first housing 411 and the second housing 412, in locations where it is inconvenient to install fasteners, an annular connector 414 can be sleeved on the first housing 411 and the second housing 412 to achieve a further fixed connection between the first housing 411 and the second housing 412.

[0174] Please see Figure 22 As shown, the area on the first housing 411 that avoids the first opening 4110 and the area on the second housing 412 that avoids the second opening 4120 are connected along the axial direction of the moisture absorption and desiccation member 42 to form a second air duct section, which is also the desorption area 4101 of the moisture absorption and desiccation housing 41. Thus, the moisture absorption and desiccation housing 41 is at least partially disposed within the main drying air duct 110, and the second air duct section inside the moisture absorption and desiccation housing 41 is connected to the first air duct section 1111 outside the main drying air duct 110, thereby forming a regeneration air duct.

[0175] Please see Figure 22As shown, an air outlet duct 4115 is formed on the first housing 411, and an air inlet duct 4125 is formed on the second housing 412. The air inlet duct 4125 and the air outlet duct 4115 are connected via the desorption section 4202 of the moisture absorption and dehumidification member 42, thus forming the aforementioned second duct section. That is, in the regeneration duct, the air in the second housing 412 passes through the desorption section 4202, enters the first housing 411, reaches the third heat exchanger 33, and finally circulates back to the second housing 412.

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

[0177] In other alternative embodiments, the air outlet duct 4115 may also be formed on the second housing 412, and the air inlet duct 4125 may be formed on the first housing 411, such that the air flow direction in the desorption section 4202 is the same as the flow direction in the moisture absorption section 4201; or, the first opening 4110 is used for air outlet and the second opening 4120 is used for air inlet, such that the air flow direction in the desorption section 4202 is the same as the flow direction in the moisture absorption section 4201.

[0178] Please see Figure 14 , Figure 16 and Figure 22 As shown, in one embodiment, the first housing 411 is provided with a first external air guide surface 4114, which is axially inclined to the moisture absorption and desiccation component 42, specifically, it is gradually inclined toward the desorption portion 4202 in the direction toward the central axis of the moisture absorption and desiccation component 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 gradually concentrates into the first opening 4110 on the moisture absorption and exhaust housing 41, avoiding the generation of eddies when the air reaches the surface of the first housing 411. Figure 22 The solid triangular arrow in the image indicates the wind direction. This ensures the airflow speed within the main drying duct 110, guarantees the moisture adsorption efficiency in the moisture absorption section 4201, reduces the energy consumption of the garment processing equipment 200, and improves the drying efficiency of the garment processing equipment 200.

[0180] In one alternative embodiment, please refer to Figure 15 and Figure 16 As shown, the width of the first outer air guide surface 4114 gradually decreases in the direction toward the central axis of the moisture absorption and desiccation component 42. That is to say, viewed from the axial direction of the moisture absorption and desiccation component 42, the first outer air guide surface 4114 is fan-shaped, which corresponds to the fan-shaped shape of the first opening 4110.

[0181] Please continue reading. Figure 16 , Figure 17 and Figure 22 As shown, in one embodiment, the second housing 412 is further provided with a second external air guide surface 4124. The second external air guide surface 4124 is axially inclined to the moisture absorption and desiccation component 42, specifically, it gradually inclines towards the desorption portion 4202 in the direction towards the central axis of the moisture absorption and desiccation component 42. The purpose of this arrangement is to guide the air in the main drying air duct 110 so that after the air flows out from the second opening 4120, it flows evenly to the second heat exchanger 34, avoiding the generation of eddies between the second housing 412 and the second heat exchanger 34.

[0182] This ensures the airflow speed within the main drying duct 110, guarantees the moisture adsorption efficiency in the moisture absorption section 4201, reduces the energy consumption of the garment processing equipment 200, and improves the drying efficiency of the garment processing equipment 200.

[0183] In one alternative embodiment, please refer to Figure 14 As shown, the width of the second outer air guide surface 4124 gradually decreases in the direction toward the central axis of the moisture absorption and desiccation component 42. That is to say, viewed from the axial direction of the moisture absorption and desiccation component 42, the second outer air guide surface 4124 is fan-shaped, which corresponds to the fan-shaped shape of the second opening 4120.

[0184] Please continue reading. Figure 16 and Figure 22 As shown, in one embodiment, a first inner air guide surface 4113 is provided on the inner wall of the first housing 411. The first inner air guide surface 4113 is inclined axially to the moisture absorption and desiccation component 42, specifically, it gradually inclines towards the desorption portion 4202 in the direction towards the central axis of the moisture absorption and desiccation component 42. The first inner air guide surface 4113 is used to guide the air flowing out of the desorption portion 4202 to change direction, avoiding abrupt reversal of air flow from the desorption portion 4202 to the third heat exchanger 33, which would cause eddies and energy loss. Optionally, the first outer air guide surface 4114 is generally parallel to the first inner air guide surface 4113.

[0185] Furthermore, by setting the first inner air guide surface 4113, the airflow speed inside the moisture absorption and dehumidification system 4 is guaranteed, the desorption efficiency of moisture in the desorption section 4202 is guaranteed, the energy consumption of the clothing processing equipment 200 is reduced, and the drying efficiency of the clothing processing equipment 200 is improved.

[0186] In one alternative embodiment, the width of the first inner air guide surface 4113 gradually decreases in the direction toward the central axis of the moisture absorption and desiccation member 42. That is, viewed from the axial direction of the moisture absorption and desiccation member 42, the first inner air guide surface 4113 is fan-shaped, which corresponds to the fan-shaped shape of the first opening 4110.

[0187] Similarly, please see Figure 16 , Figure 17 and Figure 22 As shown, in one embodiment, a second inner air guide surface 4123 is provided on the inner wall of the second housing 412. The second inner air guide surface 4123 is inclined axially to the moisture absorption and desiccation component 42, specifically, it gradually inclines towards the desorption section 4202 in the direction towards the central axis of the moisture absorption and desiccation component 42. The second inner air guide surface 4123 is used to change the direction of air flowing towards the desorption section 4202, avoiding the generation of eddies and energy loss caused by the abrupt change of direction of air flowing from the third heat exchanger 33 to the desorption section 4202. Optionally, the second outer air guide surface 4124 is generally parallel to the second inner air guide surface 4123.

[0188] In one alternative embodiment, please refer to Figure 17 As shown, the width of the second inner air guide surface 4123 gradually decreases in the direction toward the central axis of the moisture absorption and desiccation component 42. That is to say, viewed from the axial direction of the moisture absorption and desiccation component 42, the second inner air guide surface 4123 is fan-shaped, which corresponds to the fan-shaped shape of the second opening 4120.

[0189] In one embodiment, please refer to Figure 22 As shown, the inner wall of the first housing 411 is provided with a first inner air guide surface 4113, and the inner wall of the second housing 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 generally symmetrical about the radial plane of the moisture absorption and dehumidification component 42.

[0190] Please see Figure 16 and Figure 17 As shown, in one embodiment, the heating element 441 of the regeneration component 44 is disposed inside the second housing 412, that is, inside the air inlet duct 4125, to heat the air entering the desorption section 4202. Specifically, the heating element 441 can be an electric heating structure such as an electric heating tube or an electric heating plate, which is fixed to the inner wall surface of the second housing 412.

[0191] Please refer to the following: Figure 16 As shown, the heating element 441 is fixed to the inner wall of the second housing 412 and is spaced apart from the second inner air guide surface 4123. The air in the air inlet duct 4125 is guided by the second inner air guide surface 4123 before reaching the heating element 441 and being heated. The purpose of this arrangement is that the heating element 441 is closer to the surface of the desorption section 4202 of the moisture absorption and desorption component 42, making it easier for heat to be transferred to the moisture absorption and desorption component 42, thereby improving energy utilization and the desorption efficiency of the desorption section 4202.

[0192] Specifically, such 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 17 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 17 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 Figure 17 and Figure 22 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 14 and Figure 21 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 Figures 14 to 17As shown, the regeneration assembly 44 also includes a regeneration fan 442, which is connected to the second housing 412. For example, the regeneration fan 442 may be disposed inside the second housing 412 or connected to the end of the second housing 412 opposite to the second opening 4120. The regeneration fan 442 is used to provide the airflow power within the regeneration duct.

[0199] Please refer to the following: Figure 6 and Figure 7 As shown, the regeneration fan 442 is located at the third communication port 1221 of the second side plate 122 and communicates with the first air duct portion 1111 inside the second side plate 122. The second housing 412 is connected to the regeneration fan 442 via the second communication port 1212.

[0200] Please see Figure 15 , Figure 16 and Figure 20 As shown, the moisture absorption and dehumidification system 4 also includes a second driving member 43, which is fixed on the moisture absorption and dehumidification housing 41 and is used to drive the moisture absorption and dehumidification member 42 to rotate.

[0201] In one optional embodiment, the rotation center axis of the moisture-absorbing and desiccant component 42 is set to be parallel to the rotation center axis of the drum 2. The purpose of this arrangement is to facilitate the arrangement of various structures within the equipment housing 1. Specifically, since the rotation center axis of the moisture-absorbing and desiccant component 42 is parallel to the rotation center axis of the drum 2, the portion of the main drying duct 110 containing the first heat exchanger 32, the moisture-absorbing and desiccant system 4, and the second heat exchanger 34 is also parallel to the rotation center axis of the drum 2. That is, the portion of the main drying duct 110 containing the first heat exchanger 32, the moisture-absorbing and desiccant system 4, and the second heat exchanger 34 is arranged outside the drum 2 and alongside it. This maximizes the utilization of space within the equipment housing 1 and helps ensure the overall structure of the clothing processing equipment 200 is compact and miniaturized.

[0202] In one embodiment, please refer to Figure 15 and Figure 16 As shown, the second drive element 43 is disposed on the first housing 411.

[0203] Optionally, the second driving member 43 is disposed on the surface of the first housing 411 opposite to the second housing 412. That is, the second driving member 43 is disposed between the moisture absorption and dehumidification 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. This helps to reduce the impact of moisture and high temperature on the second driving member 43 and ensure the service life of the second driving member 43.

[0204] Furthermore, the second driving component 43 and the heating component 441 are located on opposite sides of the moisture absorption and desiccation component 42, which helps to balance the volume and space on both sides of the moisture absorption and desiccation system 4. This also helps to ensure that the airflow on both sides of the moisture absorption and desiccation system 4 within the main drying duct 110 is generally symmetrical, reducing pressure differences and air turbulence caused by spatial imbalance. In addition, the location of the second driving component 43 and the heating component 441 on opposite sides of the moisture absorption and desiccation component 42 also helps to maintain weight balance on both sides of the moisture absorption and desiccation system 4.

[0205] As previously mentioned, both the first opening 4110 and the second opening 4120 are fan-shaped, exposing more of the surface of the moisture-absorbing and desiccant 42 for moisture adsorption. Based on this, in one embodiment, the second drive member 43 is misaligned with the first opening 4110 in the axial direction of the moisture-absorbing and desiccant 42. (See [link to previous text]). Figure 15 As shown, the second driving member 43 is not aligned with the rotation center axis of the moisture absorption and desiccation member 42. Instead, it is offset from the first opening 4110 relative to the rotation center axis. In other words, the second driving member 43 is radially offset from the first opening 4110, and the second driving member 43 is arranged radially away from the first opening 4110. The purpose of this arrangement is to reduce the obstruction of the second driving member 43 to the first opening 4110 in the axial direction of the moisture absorption and desiccation member 42, thereby reducing the obstruction of airflow from the first heat exchanger 32 to the moisture absorption and desiccation member 42, increasing the airflow speed, and improving the drying efficiency.

[0206] Please see Figure 20 As shown, in one embodiment, the second drive member 43 includes a second motor 432. The second motor 432 is offset from the first opening 4110 relative to the rotation center axis of the moisture absorption and desiccation member 42.

[0207] In one optional embodiment, the second motor 432 includes an eccentric motor, the output shaft 4323 of which is coaxially connected to the moisture absorption and desiccation component 42. Thus, the second driving component 43 is offset relative to the central axis of the moisture absorption and desiccation component 42, but the output shaft 4323 of the second driving component 43 is aligned with the central axis of the moisture absorption and desiccation component 42. No transmission assembly is needed between the second driving component 43 and the moisture absorption and desiccation component 42, simplifying the structure of the moisture absorption and desiccation system 4. Simultaneously, this eccentric arrangement reduces the obstruction of the first opening 4110 by the second driving component 43, increases the airflow area of ​​the moisture absorption section 4201, and improves drying efficiency.

[0208] In another embodiment, the output shaft 4323 of the second drive member 43 is connected to the moisture absorption and desiccation member 42 via a transmission assembly (not shown), and the output shaft 4323 of the second drive member 43 is further offset away from the central axis of the moisture absorption and desiccation member 42 from the first opening 4110. The purpose of this arrangement is to further reduce the obstruction of the first opening 4110 by the second drive member 43, allowing the first opening 4110 to be opened as close as possible to the central axis of the moisture absorption and desiccation member 42, or even to achieve complete non-obstruction of the first opening 4110 by the second drive member 43.

[0209] Please see Figure 20 As shown, in one embodiment, the output shaft 4323 of the second drive member 43 has multiple flat surfaces 43230, which are circumferentially symmetrically distributed. When the output shaft 4323 is connected to the moisture absorption and desiccation member 42 and drives the moisture absorption and desiccation member 42 to rotate, the driving force is evenly distributed on the multiple flat surfaces 43230, which can increase the driving contact area between the output shaft 4323 and the moisture absorption and desiccation member 42. This allows the output shaft 4323 with a smaller diameter to drive the larger moisture absorption and desiccation member 42, and reduces wear and fatigue damage to both the output shaft 4323 and the moisture absorption and desiccation member 42.

[0210] Except for output shaft 4323, please refer to Figure 20 As shown, the second motor 432 also includes a motor housing 4321, a rotating assembly (not shown) disposed within the motor housing 4321, and an electronic control unit (not shown) disposed within the motor housing 4321 and connected to the rotating assembly. An output shaft 4323 passes through the motor housing 4321 and is connected to the rotating assembly. The electronic control unit is located on one side of the rotating assembly and is used to connect an external power source to the rotating assembly. The motor housing 4321 is fixedly connected to the end face of the first housing 411 facing away from the second housing 412.

[0211] In one embodiment, please refer to Figure 20 As shown, the outer surface of the motor housing 4321 is non-circular, and a protrusion 4322 is formed corresponding to the electronic control unit protruding outward. Based on this protrusion 4322, as... Figure 16 , Figure 22 As shown, a limiting groove 4112 is provided on the first housing 411 corresponding to the protrusion 4322. The inner wall of the limiting groove 4112 is used to abut against the limiting part 4311 along the rotation direction of the moisture-absorbing and dehumidifying component 42 to restrict the rotation of the limiting part 4311. That is, the limiting groove 4112 and its limiting wall are used to prevent the motor housing 4321 from rotating with the rotating assembly, so that the motor housing 4321 remains fixed on the first housing 411. In an optional embodiment, the inner wall of the limiting groove 4112 is provided on both circumferential sides of the protrusion 4322.

[0212] In one embodiment, please refer to... Figure 20As shown, the second drive unit 43 also includes a sealing housing 431. The motor housing 4321 of the second motor 432 is disposed inside the sealing housing 431, and the sealing housing 431 is sealed to the surface of the first housing 411 facing away from the second housing 412. By additionally providing a sealing housing 431, the second motor 432 is completely protected and sealed inside, which can further reduce the impact of moisture in the main drying air duct 110 on the second drive unit 43.

[0213] Specifically, such as Figure 20 As shown, the sealing 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 (bolts, screws, etc.).

[0214] Optionally, such as Figure 20 As shown, the second drive component 43 also includes a sealing washer 434, which is disposed between the sealing housing 431 and the surface of the first housing 411 facing away from the second housing 412, and surrounds the output shaft 4323. The sealing housing 431 is fixed to the first housing 411 by fasteners (such as bolts, screws, etc.). The sealing washer 434 is pressed between the sealing housing 431 and the first housing 411, thereby maintaining a sealed connection between the sealing housing 431 and the first housing 411, further reducing the possibility of moisture entering the sealing housing 431.

[0215] Correspondingly, such as Figure 20 As shown, the sealing housing 431 has a limiting portion 4311 protruding outward from the protrusion 4322, the protrusion 4322 being located within the limiting portion 4311, and the limiting portion 4311 being located within 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 protrusion 4322.

[0216] like Figure 16 and Figure 22 As shown, a motor mounting groove 4111 facing the second housing 412 is recessed axially on the end face of the first housing 411 on the side opposite to the second housing 412. A part of the sealing housing 431 and the sealing gasket 434 are disposed in the motor mounting groove 4111. The purpose of this arrangement is that, on the one hand, the shape of the motor mounting groove 4111 matches the shape of the sealing gasket 434 and the sealing housing 431, which is conducive to the overall quick positioning of the second drive component 43 when it is installed; on the other hand, the output shaft 4323 can be as close as possible to the moisture absorption and dehumidification component 42 in the axial direction, which helps to reduce the deformation of the output shaft 4323, ensure the transmission efficiency between the output shaft 4323 and the moisture absorption and dehumidification component 42, and reduce the wear on the output shaft 4323 and the moisture absorption and dehumidification component 42.

[0217] Next, please refer to Figure 18and Figure 19 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 18 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 4231 is used to protect and abut against at least a portion of the outer peripheral surface of the moisture-absorbing and desiccant layer 421. The inner fixing part 4241 is used to connect with the shaft 427. The connecting part 4242 fixes the first plate 4231 and the inner fixing part 4241 together, and the aforementioned air passage is formed between the connecting parts 4242. During the rotation of the moisture-absorbing and desiccant component 42, the air passage continuously communicates with the first opening 4110 and the air outlet duct 4115.

[0224] like Figure 18 As shown, the inner fixing part 4241 has a through-hole 42410 along the axial direction. The inner peripheral wall of the connecting hole 42410 has at least one notch 42411, and the outer peripheral surface of the shaft 427 has a protrusion 4275 that mates with the notch 42411. That is, the inner peripheral wall of the connecting hole 42410 and the outer peripheral surface of the shaft 427 are both designed as non-circular surfaces, but rather as concave-convex fits, forming a circumferential fixed connection.

[0225] In one embodiment, to facilitate the fabrication of the first fixing bracket 422, such as Figure 18 As shown, the first fixing bracket 422 includes a separate first fixing ring 423 and a bracket portion 424, that is, the first fixing ring 423 and the bracket portion 424 are manufactured separately. The first fixing ring 423 includes a first plate 4231 and a second plate 4232 connected to the first plate 4231. The second plate 4232 is used to abut against the edge of the moisture-absorbing and desiccant layer 421 facing the axial end face of the first heat exchanger 32. The bracket portion 424 includes the aforementioned connecting portion 4242 and inner fixing portion 4241. The radial outer edge of the connecting portion 4242 is located between the second plate 4232 and the moisture-absorbing and desiccant layer 421. In this way, the inner fixing portion 4241 and the connecting portion 4242 can be easily manufactured, and the structure of the first fixing ring 423 is simplified and also easy to manufacture.

[0226] Furthermore, to facilitate the fabrication and installation of the bracket portion 424 and to prevent bending deformation of the radially outer ends of the multiple spaced connecting portions 4242, in one embodiment, please refer to... Figure 18 As shown, the support portion 424 also includes a support outer ring 4243, which is connected between the radially outer ends of each connecting portion 4242. The support outer ring 4243 is located between the second plate 4232 and the moisture-absorbing and desiccant layer 421. Figure 19 As shown.

[0227] like Figure 18 and Figure 19As shown, a first groove 42430 penetrating the outer circumference of the outer ring 4243 is provided around the outer edge of the bracket outer ring 4243, and a second plate 4232 is disposed within the first groove 42430. The purpose of this arrangement is twofold: firstly, the first groove 42430 acts as a reinforcing structure, enhancing the overall strength of the bracket outer ring 4243 and preventing deformation of the bracket outer ring 4243; secondly, on the side facing the first heat exchanger 32, the height difference between the bracket outer ring 4243 and the second plate 4232 can be small, or even substantially flush.

[0228] 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 4231 can also be designed with a matching concave-convex limiting structure, so that the bracket outer ring 4243 and the first fixing ring 423 can be easily manufactured and maintain a fixed connection in the circumferential direction.

[0229] like Figure 18 As shown, the inner fixing part 4241 is provided with a second recess 42413. Similarly, the provision of the second recess 42413 can enhance the strength of the inner fixing part 4241 and reduce the risk of deformation of the inner fixing part 4241.

[0230] like Figure 18 As shown, in order to reduce obstruction of the first opening 4110, the number of connecting portions 4242 should be as small as possible, and the circumferential width of the connecting portions 4242 should be as small as possible. Furthermore, to improve the strength of each connecting portion 4242, each connecting portion 4242 is provided with a recessed area 42420. The recessed area 42420 serves as a reinforcing structure, improving the deformation resistance of the connecting portion 4242.

[0231] Further, please refer to Figure 18 As shown, each connecting part 4242 has one or more radially spaced through holes 42421. While ensuring the deformation resistance of the connecting part 4242, the through holes 42421 further increase the area of ​​the ventilation holes on the first fixed bracket 422.

[0232] In this design, multiple through holes 42421 are spaced apart on each connecting part 4242, which allows the area of ​​each through hole 42421 to be smaller and improves the deformation resistance of each connecting part 4242.

[0233] Please see Figure 18As shown, the shaft member 427 includes a first shaft segment 4271 and a second shaft segment 4273 coaxially connected. The first shaft segment 4271 has a first radial abutment portion 4272, and the second shaft segment 4273 has a second radial abutment portion 4274. The first abutment portion 4272 and the second abutment portion 4274 are located on both axial sides of the moisture-absorbing and desiccant layer 421, respectively. The first shaft segment 4271 and the second shaft segment 4273 are manufactured separately and connected from both axial sides of the moisture-absorbing and desiccant layer 421. The first abutment portion 4272 and the second abutment portion 4274 abut against the two axial sides of the moisture-absorbing and desiccant layer 421 with a larger area, and apply a certain clamping force to the moisture-absorbing and desiccant layer 421.

[0234] like Figure 18 As shown, the shape of the second sink 42413 is designed to match the shape of the first abutment 4272, and the first abutment 4272 is located inside the second sink 42413.

[0235] In one embodiment, please refer to Figure 18 As shown, the moisture-absorbing and dehumidifying component 42 also includes a second fixing bracket 425. The second fixing bracket 425 is disposed on the side of the moisture-absorbing and dehumidifying housing 41 facing the second housing 412. The second fixing bracket 425 is fixedly connected to the first fixing bracket 422. The second fixing bracket 425 is used to abut against at least a portion of the outer peripheral surface of the moisture-absorbing and dehumidifying medium layer 421 and the side end face facing away from the first housing 411.

[0236] Thus, the first fixed bracket 422 and the second fixed bracket 425 can abut and press against the two axial end faces of the moisture-absorbing and desiccant layer 421, and protect the outer peripheral surface of the moisture-absorbing and desiccant layer 421.

[0237] Specifically, please refer to Figure 18 and Figure 19 As shown, the second fixed bracket 425 includes a third plate 4251 and a fourth plate 4252 connected to each other. The third plate 4251 abuts against at least a portion of the outer peripheral surface of the moisture-absorbing and desiccant layer 421, and the fourth plate 4252 abuts against the edge of the moisture-absorbing and desiccant layer 421 facing the axial end face of the second housing 412.

[0238] The first plate 4231 and the third plate 4251 are stacked in the radial direction, or in other words, the first plate 4231 and the third plate 4251 are nested together; either the third plate 4251 nests the first plate 4231, or the first plate 4231 nests the third plate 4251. Figure 18 and Figure 19As shown, the two adjacent circumferential surfaces of the third plate 4251 and the first plate 4231 are fixedly connected by a fastening structure 426. For example, one of the two adjacent circumferential surfaces of the third plate 4251 and the first plate 4231 is provided with a fastening protrusion 4262, and the other is provided with a fastening groove 4261. Through the cooperation of the fastening protrusion 4262 and the fastening groove 4261, the first fixing ring 423 and the second fixing bracket 425 can be quickly connected without occupying an excessively large radial area, which is beneficial to reducing the outer diameter of the moisture-absorbing and dehumidifying component 42.

[0239] In one embodiment, any one of the support portion 424, the retaining ring 423, and the second fixed support 425 may be made of a metal material, such as a metal stamping, or a non-metal material, such as an injection molded part. The shaft 427 may be made of a non-metal material to facilitate the formation of its protrusion 4275 and reduce its weight; however, the shaft 427 may also be made of a metal material where permissible.

[0240] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
