[0003] In related technologies, 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 and hot air, which is then directly discharged to the external 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 the moisture content of the clothes. The humid and hot air discharged after passing through the drum is first cooled and condensed, then heated up and sent back into the drum. Summary of the Invention

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

[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 disclosure, the following detailed description is provided in conjunction with specific accompanying drawings and embodiments.

[0087] Please refer to Figures 1 to 4. This disclosure 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] As shown in Figures 1 to 4, the clothing processing equipment 200 includes a housing 1, a drying module 100, a first driving component 5, and a roller 2 disposed within the housing 1. The first driving component 5 is connected to the roller 2 and is used to drive the roller 2 to rotate.

[0090] As shown in Figures 2, 3, and 4, the equipment housing 1 may include a plurality of outer panels 15 that are interconnected with the drying module 100. In some embodiments, 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 Figures 2, 3, and 4, as well as Figure 8. The roller 2 is provided with an air inlet 21 and an air outlet 23. The space between the air inlet 21 and the air outlet 23 serves as the clothing processing space 22.

[0092] Referring to Figures 2 and 3, the device 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 two 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 some embodiments, the air inlet 21 of the roller 2 may be positioned forward, that is, towards the first support member 16.

[0094] As shown in Figures 5 and 6, 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] Referring to Figures 5, 6, and 7, in some embodiments, the drying module 100 of the garment 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 refer to Figure 6. The heat pump system 3 includes a compressor 31, a second heat exchanger 34, a throttling device 36, and a first heat exchanger 32 connected in sequence along the 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 some embodiments, as shown in Figures 6 and 7, 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 communicates with the air outlet 23 of the roller 2, and the air outlet of the main drying air duct 110 communicates with the air inlet 21 of the roller 2. Referring to Figures 6 and 7, in the heat pump system 3, the first heat exchanger 32 and the second heat exchanger 34 are arranged along the airflow direction within the main drying air duct 110, and the compressor 31 and the throttling device 36 are arranged within the receiving cavity 112 of the base assembly 11.

[0099] In addition, as shown in Figure 5, components that do not participate in air circulation, such as the first drive unit 5, are also disposed 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 some embodiments, 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] Referring to Figure 16, 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] Referring to Figure 22, the space within the moisture absorption and desorption housing 41 is divided into a moisture absorption zone 4102 and a desorption zone 4101. Referring to Figure 16, the moisture absorption and desorption 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 assembly 44 communicates with the desorption zone 4101 and is used to supply high-temperature air into the desorption zone 4101, thereby providing energy (heat) for the desorption of 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 dehumidifying component 42 is disposed in the moisture-absorbing and dehumidifying housing 41, as long as it can perform the function of moisture absorption and dehumidification. The shape of the moisture-absorbing and dehumidifying component 42 is not limited, and it can be a triangle, a square or other polygon, or a disc shape, as shown in Figures 16 and 18. The disc-shaped moisture-absorbing and dehumidifying component 42 design allows the moisture-absorbing and dehumidifying component 42 to circulate between the moisture absorption zone 4102 and the desorption zone 4101. The part of the moisture-absorbing and dehumidifying component 42 that moves to the moisture absorption zone 4102 (i.e., the moisture absorption part 4201) 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 absorption zone 4102 to absorb moisture, and so on, to remove moisture from the air, thereby achieving the effect of moisture absorption and dehumidification.

[0111] In some embodiments, the moisture absorption and desiccation component 42 is a desiccant disc. The desiccant disc in the desiccant disc can be a honeycomb or corrugated disc carrying a desiccant, capable of adsorbing and desorbing absorbed water vapor to achieve repeated desorption and regeneration. In some embodiments, the desiccant disc 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. In some embodiments, the hygroscopic agent may be zeolite, modified / synthetic zeolite, molecular sieve (including but not limited to single crystal molecular sieves or mixed crystal molecular sieves such as type A molecular sieve, type X / Y molecular sieve, ZSM molecular sieve, Beta molecular sieve, etc.), polymeric hygroscopic agent, alkali metal aluminosilicate (13X molecular sieve), lithium chloride, silica gel, modified silica gel, activated alumina, and other materials with hygroscopic properties.

[0112] In some embodiments, the moisture absorption and dehumidification component 42 is a molecular sieve dehumidification disc.

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

[0114] Then, referring to Figures 6, 7, and 8, in some embodiments, 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 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 some embodiments, the third heat exchanger 33 includes a second evaporator.

[0117] In some embodiments, 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 Figures 6 and 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 sequentially along the direction of refrigerant outflow.

[0118] In some 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 some 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 includes two parallel throttling elements, 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, with the first heat exchanger 32 and the third heat exchanger 33 connected in parallel.

[0119] Please refer to Figure 6. 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 refer to Figures 5, 6, 11 and 12. The base assembly 11 includes a base 12 and a top cover 13. As shown in Figures 5 and 6, the base 12 includes a bottom plate 120 and a first side plate 121 disposed on the upper surface of the bottom plate 120. The top cover 13 is connected to the end face of the first side plate 121 that is away from the bottom plate 120, that is, the upper end face of the first side plate 121, to define the aforementioned main drying air duct 110.

[0122] In some embodiments, as shown in Figures 7 and 16, 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 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 duct 110. It is understood that here, the rotation center axis of the moisture-absorbing and desiccant component 42 is not parallel to the airflow direction at any location within the main drying duct 110, but rather parallel to the airflow direction of the portion of the main drying 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 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 refer to Figures 5 and 6. In some embodiments, 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 top 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 some embodiments, 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 some embodiments, as shown in Figures 11 and 12, the base plate 120 is provided with a water channel 113 located within the main drying air duct 110. In other words, condensate drips onto the upper surface of the base plate 120, and the lower portion of the space in the main drying air duct 110 can serve as the water channel 113.

[0128] As shown in Figures 5, 6, and 11, 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, connecting the water collection box 123 to the water flow channel 113. Furthermore, as shown in Figure 11, the bottom surface of the water flow channel 113 (i.e., the portion of the upper surface of the base plate 120 located within the main drying air duct 110) gradually slopes downwards towards the first drain outlet 1210. This facilitates the automatic flow of condensate to 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] As shown in Figure 12, 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 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 some embodiments, depending on the positional relationship between the first air duct section 1111 and the main drying air duct 110, the first drain outlet 1210 may be sequentially connected to the main drying air duct 110 and the first drain outlet 1210.

[0131] Referring to Figures 6, 11, and 12, in some embodiments, 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] As shown in Figures 6, 11, and 12, in some embodiments, a plurality of raised blocks 124 protrude from the upper surface of the base plate 120. The raised blocks 124 are used to support the isolation plate 14 at a certain height, that is, the isolation plate 14 is located on the end face of the raised block 124 facing the upper cover 13. In order to evenly support multiple positions of the isolation plate 14, the raised blocks 124 are designed with different shapes and positions. In some embodiments, referring to Figure 6, 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 (a plurality of second raised blocks 1242) are spaced apart 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] As shown in Figures 11 and 12, in some embodiments, a portion of the raised blocks 124 (third raised blocks 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. In some embodiments, a portion of the moisture absorption and desiccation housing 41 has a clearance opening 143 on the isolation plate 14 corresponding to the first mounting cavity 1240, as shown in Figure 6. Thus, the moisture absorption and desiccation system 4 can be partially located above and partially located below the isolation plate 14, and isolated from the water channel 113. The purpose of this arrangement is to allow the moisture absorption and desiccation 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 desiccation system 4 and consequently reducing the overall height of the garment processing equipment 200.

[0134] In some embodiments, 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, as shown in Figures 11 and 12, to further reduce the position of the moisture absorption and dehumidification system 4.

[0135] Please refer to Figure 11. 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 drainage holes 141 are 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 drainage holes 141, and then through the drainage holes 141 into the water channel 113 below the isolation plate 14.

[0136] Furthermore, condensation will also occur around the first heat exchanger 32. Therefore, in some embodiments, as shown in Figures 6 and 11, a water-blocking strip 142 is provided on the upper surface of the isolation plate 14. 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 portion of 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, as shown in Figure 6.

[0137] Referring to Figures 6 and 12, in some embodiments, a downwardly extending flange 144 is formed on the partition plate 14 around the periphery of the clearance opening 143. In some embodiments, the flange 144 is a closed enclosure. Therefore, the flange 144 is located within the first mounting cavity 1240. This arrangement is intended to guide the moisture absorption and dehumidification system 4 during assembly. Furthermore, the interference fit between the flange 144 and the first pad further prevents condensate from entering the first mounting cavity 1240 from the water channel 113.

[0138] In some embodiments, the isolation plate 14 may be fixedly connected to at least one shim block 124 by fasteners, and in some embodiments, to a third shim block 1243 by fasteners. The fasteners may be bolts, screws, or other fastening structures.

[0139] In some embodiments, at least one shim 124 is connected to the lower surface of the partition plate 14 via a limiting fit structure. In some embodiments, 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 some embodiments, other shims 124 may also be connected to the isolation plate 14 via fasteners and / or limiting fit structures. In some embodiments, the third shim 1243 is connected to the isolation plate 14 via fasteners, and in some embodiments, the second shim 1242 is connected to the isolation plate 14 via a limiting fit structure, etc.

[0141] Referring to Figure 13, in some embodiments, 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. In some embodiments, the upper surface of the first side plate 121 and the second side plate 122 is 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 some embodiments, a sealing element (not shown), such as an elastic sealing strip, is provided between the sealing protrusion 1311 and the sealing groove 1312. In addition, the first side plate 121, the second side plate 122 and the top 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, so as to ensure the sealing between the first side plate 121, the second side plate 122 and the top cover 13.

[0142] As shown in Figure 6, 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. As shown in Figures 6 and 7, 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 portion 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.

[0143] Referring to Figure 4, the first driving component 5 is used to drive the roller 2 to rotate. In some embodiments, the first driving component 5 may 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.

[0144] In some embodiments, the first drive 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. In some embodiments, the tensioning member may be a spring, a tension rope, etc.

[0145] As shown in Figure 8, in some embodiments, the base plate 120 is provided with a mounting portion 127, 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.

[0146] The rear side of the base 12 is used to connect with the rear side plate. As shown in FIG9, in some embodiments, the edge of the base plate 120 is provided with a plurality of guide blocks 126, which 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.

[0147] Please refer to Figures 6, 7 and 11. In some embodiments, 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 encloses and defines the front air duct 1250. As shown in Figure 11, the third side plate 125 is provided with a fourth connecting port 1251 that communicates with the main drying air duct 110. The end face of the third side plate 125 away from the base plate 120 defines a fifth connecting port 1252. The second connecting port 1212 is used to communicate with the air outlet 23 of the roller 2.

[0148] In some embodiments, as shown in Figures 2 and 3, the first support member 16 has a third opening 161 corresponding to the air inlet 21 of the roller 2. This 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 in communication with 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.

[0149] Please refer to Figures 2 and 3 for details. A filter duct 160 is formed on the inner peripheral wall of the third opening 161 on the first support member 16. 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. In some embodiments, 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. In some embodiments, 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.

[0150] Referring to Figures 2 and 3, 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.

[0151] Referring to Figures 6 and 12, in some embodiments, 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. Referring to Figures 16 and 17, the heating element 441 is an electric heating element in some embodiments. In this case, the power line is used to provide power to the electric heating element.

[0152] As shown in Figures 6 and 12, 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. passing through the first wire hole 132. The form of the wire fixing blocks 133 is not limited.

[0153] Please refer to Figure 4. In some embodiments, the garment 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.

[0154] In some embodiments, as shown in FIG4, the main circulating fan 6 is located downstream of the second heat exchanger 34 and is used to deliver air from the main drying duct 110 to the air inlet 21 of the drum 2.

[0155] In some embodiments, 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.

[0156] Please refer to Figures 6 and 12. 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. In some embodiments, the mounting positions 135 may be mounting holes 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.

[0157] In some embodiments, any one of the base 12, the partition plate 14, and the top cover 13 may be a plastic component, and in some embodiments, it is 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.

[0158] Next, please refer to Figures 6, 7 and 10. 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.

[0159] During operation, the 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 pipe 35 during compressor 31 vibration and to prevent breakage of the refrigerant pipe 35, particularly the portion of the refrigerant pipe 35 near the compressor 31, as shown in Figure 10, in some embodiments, the refrigerant pipe 35 includes multiple pipe segments 351, with adjacent pipe segments 351 bent relative to each other in the horizontal and / or vertical directions. In some embodiments, 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 left-right movement, 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 due to deflection and bending is significantly reduced compared to pulling and squeezing along the length direction. When multiple pipe sections 351 are bent and connected in sequence, the pulling and squeezing of the refrigerant pipes 35 caused by the vibration of the compressor 31 will be significantly improved.

[0160] 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.

[0161] In some embodiments, the refrigerant pipe 35 is a copper pipe. Copper pipes have good ductility, making it easy to manufacture multiple pipe segments 351 with relative bends. In some embodiments, adjacent pipe segments 351 are smoothly connected to reduce the resistance to refrigerant flow between pipe segments 351 and to facilitate the assembly operation of the garment processing device 200.

[0162] Please refer to Figures 6 and 8. In some embodiments, the housing of the compressor 31 is provided with a plurality of first fixing ears 311, each of which has a fixing hole 3110. A first fastener 37 is disposed in the fixing hole 3110 and connected to the base plate 120. The outer diameter of the first fastener 37 is smaller than the inner diameter of the fixing hole 3110. Thus, an annular gap is formed around the first fastener 37. The purpose of this arrangement is to accommodate the vibration of the compressor 31 as described above. If the first fixing ears 311 and the first fastener 37 are fixedly connected without gap, the continuous vibration of the compressor 31 may cause damage to the first fixing ears 311 of the compressor 31, or even damage to the housing 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 is buffered and consumed by the bent pipe section 351, reducing damage to the compressor 31 itself and also slowing down the overall vibration of the clothing processing equipment 200.

[0163] In some embodiments, as shown in FIG10, in the heat pump system 3, a plurality of sequentially connected pipe segments 351 define a clearance space 350 for accommodating the first drive member 5. This arrangement is intended to accommodate both the refrigerant pipe 35 and the first drive member 5 within the receiving cavity 112 of the base plate 120. The refrigerant pipe 35 must avoid the first drive member 5. In some embodiments, at least a portion of the refrigerant pipe 35 is located below the first drive member 5 to avoid affecting the connection between the first drive member 5 and the roller 2. Therefore, the clearance space 350 is defined by the portion of pipe segment 351 located below the first drive member 5 and the portion of pipe segment 351 located around the first drive member 5 adapted to the shape of the first drive member 5.

[0164] Next, we will introduce the moisture absorption and dehumidification system 4 according to an embodiment of this disclosure.

[0165] Please refer to Figures 15, 16, 17, and 22. In some embodiments, the moisture absorption and desiccation system 4 has a first opening 4110 on the moisture absorption and desiccation housing 41, as shown in Figures 14, 16, and 22. The moisture absorption and desiccation housing 41 also has a second opening 4120. The first opening 4110 and the second opening 4120 respectively expose a portion of the surface of the moisture absorption and desiccation component 42, allowing the first opening 4110 and the second opening 4120 to communicate via the moisture-absorbing portion 4201 of the moisture absorption and desiccation component 42. Air passes sequentially through the passage formed by the first opening 4110, the moisture-absorbing portion 4201, and the second opening 4120, and the moisture therein can be absorbed by the moisture-absorbing portion 4201. The portion inside the moisture absorption and desiccation housing 41 between the first opening 4110 and the second opening 4120 is referred to as the moisture-absorbing area 4102.

[0166] In some embodiments, as shown in Figures 14, 16, and 22, a first opening 4110 is formed on the first axial end face of the moisture-absorbing and desiccant housing 41, exposing a portion of the first axial end face of the moisture-absorbing and desiccant member 42. This allows the first opening 4110 to be manufactured in a simple form and to have a larger area, facilitating an increase in the air passage area of ​​the moisture-absorbing section 4201 and improving the adsorption efficiency of moisture within the moisture-absorbing section 4201.

[0167] In some embodiments, as shown in Figures 15, 16, 17, and 22, a second opening 4120 is formed on the second axial end face of the moisture-absorbing and desiccant housing 41, exposing a portion of the second axial end face of the moisture-absorbing and desiccant member 42. This also allows the second opening 4120 to be manufactured in a simple form and to have a larger area, facilitating an increase in the air passage area of ​​the moisture-absorbing section 4201 and improving the adsorption efficiency of moisture within the moisture-absorbing section 4201.

[0168] In some embodiments, as shown in Figures 16, 21, and 22, a first opening 4110 is formed on the first axial end face of the moisture-absorbing and desiccant housing 41, and a 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.

[0169] In some embodiments, as shown in Figures 16, 17, and 22, the first opening 4110 and the second opening 4120 are axially connected 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.

[0170] In some embodiments, 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. In some embodiments, 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. In some embodiments, 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. In some embodiments, 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. In some embodiments, 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.

[0171] Referring to Figure 7, in some embodiments, the first heat exchanger 32, the moisture absorption and desiccation system 4, and the second heat exchanger 34 are arranged sequentially along the axial direction of the moisture absorption and desiccation component 42 within the main drying duct 110. The solid triangular arrows in Figure 7 indicate the airflow direction. Within the main drying duct 110, at least the portion housing the first heat exchanger 32, the moisture absorption and desiccation system 4, and the second heat exchanger 34 is generally a square space. This allows air to pass straight through the first heat exchanger 32, the moisture absorption and desiccation system 4, and the second heat exchanger 34 sequentially, avoiding air reversal and eddies, and ensuring the highest airflow efficiency between the first heat exchanger 32, the moisture absorption and desiccation system 4, and the second heat exchanger 34. Furthermore, within the moisture absorption and desiccation component 42, the airflow direction is completely parallel to the direction of the vents in the component 42, allowing the air dried by the component 42 to exit directly, minimizing the loss of air kinetic energy and wind speed. Depending on specific needs, the first heat exchanger 32, the moisture absorption and dehumidification system 4, and the second heat exchanger 34 can be arranged sequentially at a certain distance along the axial direction of the moisture absorption and dehumidification component 42 within the main drying air duct 110, or they can be arranged without spacing, as long as it does not affect their respective operation.

[0172] Please refer to Figures 16, 17, 21, and 22. 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, referring to Figures 16 and 17, in some embodiments, 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 fitted onto 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.

[0173] Referring to Figure 22, 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.

[0174] Please refer to Figure 22. 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.

[0175] 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.

[0176] In some 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.

[0177] Please refer to Figures 14, 16 and 22. In some embodiments, the first housing 411 is provided with a first external air guide surface 4114. The first external air guide surface 4114 is axially inclined to the moisture absorption and desiccation member 42. In some embodiments, it is gradually inclined toward the desorption part 4202 in the direction toward the central axis of the moisture absorption and desiccation member 42.

[0178] 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. In Figure 22, the solid triangular arrows indicate the airflow direction. This ensures the airflow speed in the main drying air duct 110, guarantees the moisture adsorption efficiency in the moisture absorption section 4201, reduces the energy consumption of the clothing processing equipment 200, and improves the drying efficiency of the clothing processing equipment 200.

[0179] In some embodiments, as shown in Figures 15 and 16, 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 member 42. That is, viewed from the axial direction of the moisture absorption and desiccation member 42, the first outer air guide surface 4114 is fan-shaped, which corresponds to the fan-shaped shape of the first opening 4110.

[0180] Please refer to Figures 16, 17, and 22. In some embodiments, 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. In some embodiments, it is gradually inclined 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.

[0181] 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.

[0182] In some embodiments, as shown in FIG14, 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 member 42. That is, viewed from the axial direction of the moisture absorption and desiccation member 42, the second outer air guide surface 4124 is fan-shaped, which corresponds to the fan-shaped shape of the second opening 4120.

[0183] Please refer to Figures 16 and 22. In some embodiments, 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 member 42. In some embodiments, it is gradually inclined toward the desorption section 4202 in the direction toward the central axis of the moisture absorption and desiccation member 42. The first inner air guide surface 4113 is used to guide the air flowing out of the desorption section 4202 to change direction, avoiding the abrupt change of direction of the air flowing from the desorption section 4202 to the third heat exchanger 33, which would cause eddies and wind energy loss. In some embodiments, the first outer air guide surface 4114 is generally parallel to the first inner air guide surface 4113.

[0184] 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.

[0185] In some embodiments, 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.

[0186] Similarly, referring to Figures 16, 17, and 22, in some embodiments, 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 member 42. In some embodiments, it is gradually inclined toward the desorption section 4202 in the direction toward the central axis of the moisture absorption and desiccation member 42. The second inner air guide surface 4123 is used to change the direction of air flowing toward the desorption section 4202, avoiding the generation of eddies and energy loss caused by the abrupt change of direction when the air flows from the third heat exchanger 33 to the desorption section 4202. In some embodiments, the second outer air guide surface 4124 is generally parallel to the second inner air guide surface 4123.

[0187] In some embodiments, as shown in FIG17, 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 member 42. That is, viewed from the axial direction of the moisture absorption and desiccation member 42, the second inner air guide surface 4123 is fan-shaped, which corresponds to the fan-shaped shape of the second opening 4120.

[0188] In some embodiments, as shown in FIG22, a first inner air guide surface 4113 is provided on the inner wall of the first housing 411, and a second inner air guide surface 4123 is provided on the inner wall of the second housing 412. 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 desiccation component 42.

[0189] Referring to Figures 16 and 17, in some embodiments, the heating element 441 of the regeneration component 44 is disposed within the second housing 412, i.e., within the air inlet duct 4125, to heat the air entering the desorption section 4202. In some embodiments, the heating element 441 may 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.

[0190] Referring to Figure 16, 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.

[0191] As shown in Figure 17, the heating element 441 is fixed to the inner wall of the second housing 412 by a 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. In some embodiments, for an electric heating tube, the fastener can be adapted to the surface of the tube body of the electric heating tube; in some embodiments, for an electric heating plate, the fastener can be adapted to the plate-like surface.

[0192] Referring to Figure 17, in some embodiments, 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. In some embodiments, the mounting plate 45 is flat and maintains a large contact area with the heating element 441 to ensure the installation stability of the heating element 441.

[0193] Understandably, as shown in Figure 17, 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.

[0194] In some embodiments, as shown in Figures 17 and 22, a mounting platform 4121 protruding towards the first housing 411 is provided on the second inner air guide surface 4123. 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. This ensures that 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.

[0195] The shape of the mounting platform 4121 is designed to minimize its space occupation within the air inlet duct 4125 and to reduce obstruction of the airflow path. In some embodiments, the mounting platform 4121 is generally plate-shaped, with its thickness direction being generally perpendicular to the airflow direction within the air inlet duct 4125. Therefore, its thickness is set to be small, which can reduce obstruction of airflow.

[0196] Please refer to Figures 14 and 21. 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 lines to pass through.

[0197] Referring to Figures 14 to 17, the regeneration assembly 44 also includes a regeneration fan 442, which is connected to the second housing 412. In some embodiments, the regeneration fan 442 may be disposed within 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.

[0198] Referring to Figures 6 and 7, 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 1111 inside the second side plate 122. The second housing 412 is connected to the regeneration fan 442 via the second communication port 1212.

[0199] Please refer to Figures 15, 16 and 20. 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.

[0200] In some embodiments, 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. In some embodiments, the rotation center axis of the moisture-absorbing and desiccant component 42 is parallel to the rotation center axis of the drum 2. In this case, the portion of the main drying duct 110 in which the first heat exchanger 32, the moisture-absorbing and desiccant system 4, and the second heat exchanger 34 are located is also parallel to the rotation center axis of the drum 2. That is, the portion of the main drying duct 110 in which the first heat exchanger 32, the moisture-absorbing and desiccant system 4, and the second heat exchanger 34 are located outside the drum 2 and arranged side by side with the drum 2. This maximizes the utilization of space within the equipment housing 1 and helps to ensure that the overall structure of the clothing processing equipment 200 is compact and miniaturized.

[0201] In some embodiments, as shown in Figures 15 and 16, a second drive member 43 is disposed on a first housing 411.

[0202] In some embodiments, the second drive member 43 is disposed on the surface of the first housing 411 facing away from the second housing 412. That is, the second drive 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 drive member 43 is low-temperature air, and the second drive 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 drive member 43 and ensure the service life of the second drive member 43.

[0203] 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.

[0204] As mentioned earlier, both the first opening 4110 and the second opening 4120 are fan-shaped, exposing more of the surface of the moisture-absorbing and desiccant component 42 for moisture adsorption. Based on this, in some embodiments, the second drive component 43 is misaligned with the first opening 4110 in the axial direction of the moisture-absorbing and desiccant component 42. Referring to Figure 15, the second drive component 43 is not aligned with the rotation center axis of the moisture-absorbing and desiccant component 42, but rather offset from the first opening 4110 relative to the rotation center axis. In other words, the second drive component 43 is radially offset from the first opening 4110, and is arranged radially away from the first opening 4110. The purpose of this arrangement is to reduce the obstruction of the second drive component 43 to the first opening 4110 in the axial direction of the moisture-absorbing and desiccant component 42, thereby reducing the obstruction to the flow of air from the first heat exchanger 32 to the moisture-absorbing and desiccant component 42, increasing airflow velocity, and improving drying efficiency.

[0205] Referring to Figure 20, in some embodiments, 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.

[0206] In some embodiments, 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 drive 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 drive component 43 is aligned with the central axis of the moisture absorption and desiccation component 42. No transmission assembly is needed between the second drive 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 drive component 43, increases the airflow area of ​​the moisture absorption section 4201, and improves drying efficiency.

[0207] In some embodiments, 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.

[0208] Referring to Figure 20, in some embodiments, 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.

[0209] In addition to the output shaft 4323, as shown in Figure 20, 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. The 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 supply and 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.

[0210] In some embodiments, as shown in FIG20, the outer surface of the motor housing 4321 is a non-circular surface, and a protrusion 4322 is formed by the corresponding electronic control unit protruding outward. Based on this protrusion 4322, as shown in FIG16 and FIG22, a limiting groove 4112 is provided on the first housing 411 corresponding to the protrusion 4322. The inner sidewall of the limiting groove 4112 is used to abut against the limiting part 4311 along the rotation direction of the moisture absorption and desiccation member 42 to limit 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 some embodiments, the inner wall of the limiting groove 4112 is provided on both circumferential sides of the protrusion 4322.

[0211] In some embodiments, referring to Figure 20, the second drive unit 43 further includes a sealing housing 431. The motor housing 4321 of the second motor 432 is disposed within 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 duct 110 on the second drive unit 43.

[0212] In some embodiments, as shown in FIG20, 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.).

[0213] In some embodiments, as shown in FIG20, the second drive member 43 further 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.

[0214] Correspondingly, as shown in Figure 20, the sealing housing 431 has a limiting portion 4311 protruding outward from the protrusion 4322. The protrusion 4322 is located inside the limiting portion 4311, and the limiting portion 4311 is located inside 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.

[0215] As shown in Figures 16 and 22, 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 driving 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.

[0216] Next, please refer to Figures 18 and 19 to describe the moisture absorption and desiccation component 42 of this disclosure embodiment.

[0217] As shown in Figure 18, the moisture absorption and desiccation component 42 includes a moisture absorption and desiccation medium layer 421, a first fixed bracket 422, and a shaft 427. The moisture absorption and desiccation 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 absorption and desiccation 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 absorption and desiccation medium layer 421 to rotate.

[0218] 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.

[0219] In order to conveniently and effectively fix the moisture-absorbing and desiccant layer 421 and to maximize the area of ​​the air passage, in some embodiments, 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.

[0220] In some embodiments, 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 drive 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.

[0221] As shown in Figure 18, in some embodiments, 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.

[0222] 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.

[0223] As shown in Figure 18, the inner fixing part 4241 has an axially penetrating connecting hole 42410, and the inner peripheral wall of the connecting hole 42410 has at least one notch 42411. 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.

[0224] In some embodiments, to facilitate the fabrication of the first fixing bracket 422, as shown in FIG18, 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 fabricated 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 fabricated, and the structure of the first fixing ring 423 is simplified and also easy to manufacture.

[0225] In some embodiments, in order to facilitate the fabrication and installation of the bracket portion 424 and to avoid bending deformation of the radially outer ends of the multiple spaced connecting portions 4242, in some embodiments, as shown in FIG18, the bracket portion 424 further includes a bracket outer ring 4243. The bracket outer ring 4243 is connected between the radially outer ends of each connecting portion 4242 and is located between the second plate 4232 and the moisture-absorbing and desiccant layer 421, as shown in FIG19.

[0226] As shown in Figures 18 and 19, a first recessed groove 42430 is provided around the outer edge of the outer ring 4243, penetrating the outer circumferential surface of the outer ring 4243, and a second plate 4232 is disposed within the first recessed groove 42430. The purpose of this arrangement is twofold: firstly, the first recessed groove 42430 acts as a reinforcing structure, enhancing the overall strength of the outer ring 4243 and preventing deformation; secondly, on the side facing the first heat exchanger 32, the height difference between the outer ring 4243 and the second plate 4232 can be small, or even substantially flush.

[0227] In some embodiments, 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 corresponding 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.

[0228] As shown in Figure 18, 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.

[0229] As shown in Figure 18, to minimize 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, a recessed area 42420 is provided on each connecting portion 4242. The recessed area 42420 serves as a reinforcing structure, improving the deformation resistance of the connecting portion 4242.

[0230] In some embodiments, as shown in FIG18, each connecting portion 4242 has one or more radially spaced through holes 42421. While ensuring the deformation resistance of the connecting portion 4242, the through holes 42421 further increase the area of ​​the ventilation holes on the first fixed bracket 422.

[0231] 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.

[0232] Referring to Figure 18, 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 opposite 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 opposite axial sides of the moisture-absorbing and desiccant layer 421. The first abutment portion 4272 and the second abutment portion 4274 abut against the opposite axial sides of the moisture-absorbing and desiccant layer 421 with a larger area, applying a certain clamping force to the moisture-absorbing and desiccant layer 421.

[0233] As shown in Figure 18, 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.

[0234] In some embodiments, as shown in FIG18, the moisture-absorbing and desiccant component 42 further includes a second fixing bracket 425. The second fixing bracket 425 is disposed on the side of the moisture-absorbing and desiccant 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 desiccant medium layer 421 and the side end face facing away from the first housing 411.

[0235] 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.

[0236] In some embodiments, as shown in Figures 18 and 19, the second fixing 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.

[0237] 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 within the first plate 4231, or vice versa. As shown in Figures 18 and 19, the two adjacent circumferential surfaces of the third plate 4251 and the first plate 4231 are fixedly connected by a fastening structure 426. In some embodiments, 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, a quick connection between the first fixing ring 423 and the second fixing bracket 425 is achieved without occupying an excessively large radial area, which helps to reduce the outer diameter of the moisture-absorbing and dehumidifying component 42.

[0238] In some embodiments, any one of the bracket portion 424, the retaining ring 423, and the second fixed bracket 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 is made of a non-metal material in some embodiments to facilitate the formation of its protrusion 4275 and to reduce its weight; however, the shaft 427 may also be made of a metal material where permissible.

[0239] The above description is merely an embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
