[0084] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. This description is merely illustrative of the basic principles of the invention and is not intended to limit it.

[0085] To enable those skilled in the art to better understand this disclosure, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0086] In clothing processing devices, such as dryers or washer-dryer combos, there are heating modules and moisture-absorbing and dehumidifying modules. The moisture-absorbing and dehumidifying modules can absorb moisture from the drum, and the heating modules provide heat energy to the moisture-absorbing and dehumidifying modules to desorb the moisture adsorbed by the moisture-absorbing and dehumidifying components. This cycle can dry the clothes in the clothing processing device.

[0087] The moisture absorption and dehumidification module includes a wheel assembly and a housing for accommodating the wheel assembly. The wheel assembly is rotatably disposed within the housing. Two or more pairs of partition ribs are provided on the inner walls of the upper and lower end faces of the housing to divide the internal space of the housing into a moisture absorption area and a moisture dehumidification area. During the rotation of the wheel assembly within the housing, the moisture absorbed in the moisture absorption area is absorbed by the wheel assembly, thereby causing the wheel assembly to output dry gas. The dry gas is then transported to the drum through the dehumidification area. For details, please refer to the technical solution disclosed in patent document application number "202222327022.1" entitled "Washer-Dryer Combo".

[0088] In related technologies, the partition ribs are arranged radially along the disc of the disc assembly. This causes the disc to easily get stuck with the partition ribs due to excessive contact area during the rotation of the disc assembly within the housing, thus affecting the normal operation of the disc assembly.

[0089] Based on the above-mentioned technical problems, this disclosure provides a wheel assembly, a moisture absorption and desiccation module, and a clothing treatment device, aiming to at least partially solve the technical problem that the wheel is easily jammed by the partition ribs, affecting the normal operation of the wheel assembly.

[0090] In a first aspect, this disclosure provides a roulette wheel assembly. FIG1 shows a structural schematic diagram of the roulette wheel assembly in some embodiments, FIG2 shows a structural schematic diagram of FIG1 from another perspective, and FIG3 shows an exploded schematic diagram of FIG1. ​​Referring to FIG1-3, the roulette wheel assembly 100 includes a support housing 11 and a roulette wheel 12. The support housing 11 is provided with an outer ring 111, and a central member 15 is provided at the center of the support housing 11. The outer peripheral surface of the central member 15 and the inner peripheral surface of the outer ring 111 are connected by a support rib 13. The support rib 13 and the radial direction of the outer ring 111 have an included angle. The roulette wheel 12 is disposed between the outer ring 111 and the central member 15 and is mounted on the support rib 13.

[0091] The support rib 13 connects the outer peripheral surface of the center component 15 and the inner peripheral surface of the outer ring 111. The support rib 13 is roughly elongated. The radial direction of the support rib 13 and the outer ring 111 is at an angle, indicating that the extension direction of the support rib 13 is different from that of the outer ring 111. During the rotation of the turntable assembly, the support rib 13 will gradually come into contact with the partition rib on the housing of the moisture absorption and desiccation module, thereby reducing the contact area between the support rib 13 and the partition rib. Due to the reduced contact area, the friction between the turntable assembly 100 and the housing of the moisture absorption and desiccation module is also reduced, which reduces the risk of the turntable assembly 100 being stuck by the partition rib, enabling the turntable assembly 100 to work normally and has good practicality.

[0092] Figure 4 shows a schematic diagram of the structure of the support housing in Figure 1, and Figure 5 shows a top view of Figure 4. Referring to Figures 4 and 5, in some embodiments, multiple support members 13 may be provided. One end of each support rib 13 may be connected to the central member 15, and the other end of each support rib 13 extends radially to the inner circumferential surface of the outer ring 111 to evenly support the wheel 12.

[0093] Referring to Figures 4 and 5, in some embodiments, the outer peripheral surfaces of the support rib 13 and the center member 15 may be tangent. In other embodiments, the outer peripheral surfaces of the support rib 13 and the center member 15 may not be tangent, and this is not a limitation.

[0094] Referring to Figures 4 and 5, in some embodiments, the included angle between adjacent support ribs 13 can be 90°, that is, adjacent support ribs 13 are perpendicular to each other, so as to make the support for the wheel 12 as balanced as possible. In other embodiments, adjacent support ribs 13 may not be perpendicular to each other. In some embodiments, the included angle between adjacent support ribs 13 is greater than 90°, which is not limited here.

[0095] In some embodiments, four support ribs 13 are provided to ensure that the support for the wheel 12 is as comprehensive and balanced as possible. In other embodiments, the number of support ribs 13 may be three, five, or more, and there is no limitation herein.

[0096] Referring to Figures 4 and 5, in some embodiments, the support housing 11 can be cylindrical, with at least a portion of its outer circumferential surface provided with teeth 113 to mesh with a drive wheel disposed outside the support disc 12. The central member 15 of the support housing 11 is rotatably connected to a rotating shaft (not shown), and the support housing 11 is driven to rotate around the rotating shaft when the drive wheel rotates.

[0097] Referring to Figures 4 and 5, in some embodiments, the aforementioned teeth 113 may be provided on the upper part of the outer peripheral surface of the support housing 11, and the lower part of the outer ring 111 of the support housing 11 may be a smooth curved surface. A support ring 114 may be provided at the bottom of the outer ring 111 of the support housing 11 to support the edge of the wheel 12, and the aforementioned plurality of support ribs 13 may be connected to the support ring 114.

The reinforcing ring 14 may be concentrically arranged with the outer ring 111. The arrangement of the reinforcing ring 14 can strengthen the structure of the support rib 13 on the one hand, and support the wheel 12 on the other hand, thereby improving the support effect of the wheel 12.

[0099] Referring to Figures 4 and 5, in some embodiments, two or more reinforcing rings 14 may be provided, with the two or more reinforcing rings 14 spaced apart along the radial direction of the outer ring 111 between the positioning part 112 and the side wall of the outer ring 111. In other embodiments, only one, three, or four reinforcing rings 14 may be provided, and no limitation is made here.

[0101] It should be noted that the positioning part 112, the support ring 114, the reinforcing ring 14, and the support rib 13 constitute a support structure for the wheel 12. The top plane of the support structure is at the same height so that the wheel 12 can be stably placed on the support structure. Similarly, the bottom plane of the support structure is also at the same height.

[0102] Referring to Figure 3, in some embodiments, the central component 15 includes a first clamp 151 and a second clamp 152. The positioning part 112 can be connected to the outer peripheral surface of the bottom of the first clamp 15. The second clamp 152 is fitted onto the first clamp 151. The wheel 12 is fitted onto the second clamp 152. The top of the second clamp 152 is provided with a limiting part 1525 extending to the outer peripheral surface of the second clamp 152. The limiting part 1525 is pressed onto the wheel 12 to fix the wheel 12, so that the wheel 12 and the support housing 11 are relatively fixed. When the drive wheel rotates to drive the support housing 11 to rotate around the axis, the wheel 12 also rotates around the axis with the support housing 11 to realize the moisture absorption and dehumidification function.

[0103] Figure 6 shows a schematic diagram of the wheel assembly shown in Figure 1 with the wheel removed. Figure 7 shows a partially enlarged schematic diagram at point A in Figure 6. Figure 8 shows a schematic diagram of the second clamp in Figure 6. Figure 9 shows an enlarged schematic diagram at point B in Figure 4. In conjunction with Figures 6-9, in some embodiments, the center member 15 includes a first clamp 151 and a second clamp 152. The first clamp 151 is rotatably mounted on the rotating shaft.

The ends of the connecting posts 1521 facing the positioning part 112 are provided with a plurality of second connecting holes, so that the second clamp 152 can be installed on the positioning part 112 by means of connecting members passing through the first connecting holes 1511 and the second connecting holes.

[0105] Referring to Figures 8 and 9, in a specific implementation, the positioning part 112 can be annular, and a receiving part 1515 can be provided on the top of the positioning part 112. The receiving parts 1515 are spaced apart on the outer peripheral surface of the first clamp 151.

[0106] Referring to Figures 6-9, in some embodiments, a first guide member 1513 is provided on the outer peripheral surface of the first clamp 151, and the first guide member 1513 is arranged along an axis parallel to the first clamp 151. A second guide member 1523 is provided on the second clamp 152, and the second guide member 1523 and the first guide member 1513 are interlocked. During the process of the second clamp 152 being fitted onto the first clamp 151, the interlocking guidance of the second guide member 1523 and the first guide member 1513 can automatically align the first connecting hole 1511 on the connecting block 1512 with the second connecting hole on the corresponding connecting post 1521, and can limit the circumferential displacement between the second clamp 152 and the first clamp 151, thereby improving assembly efficiency.

[0107] Referring to Figure 7, in some embodiments, the first guide 1513 may be a guide protrusion disposed on the outer peripheral surface of the first clamp 151, and referring to Figure 8, the second guide 1523 may be a guide groove disposed on the inner wall of the second clamp 152. The guide protrusion can slide within the guide groove to provide guidance for the assembly between the second clamp 152 and the first clamp 151.

[0108] Referring to Figures 6-9, in some embodiments, one first guide member 1513 may be provided, and multiple second guide members 1523 may be provided at circumferential intervals around the second clamp 152. The central angles of adjacent second guide members 1523 and adjacent connecting posts 1521 are the same. The first guide member 1513 can be connected with any one of the second guide members 1523. Since the central angles of adjacent second guide members 1523 and adjacent connecting posts 1521 are the same, during operation, any second guide member 1523 can be selected to cooperate with the first guide member 1513. This also allows the first connecting hole 1511 on the connecting block 1512 to automatically align with the corresponding second connecting hole on the connecting post 1521, improving operational efficiency.

[0111] Referring to Figure 8, in some embodiments, the top of the second clamp 152 is provided with a limiting portion 1525 extending towards the side wall of the outer ring 111. The wheel 12 is disposed between the limiting portion 1525 and the positioning portion 112, so as to further limit the displacement of the wheel 12 by clamping it through the limiting portion 1525 and the aforementioned support structure. The limiting portion 1525 can be annular and can be integrally formed on the top of the second clamp 152.

[0112] In some embodiments, an elastic layer may be provided between the sidewall of the outer ring 111 and the circumferential surface of the wheel 12, so that there is a certain compressive force between the circumferential surface of the wheel 12 and the sidewall of the outer ring 111. This allows the wheel 12 to be assembled in the elastic layer with an interference fit, thereby improving the reliability of the assembly between the wheel 12 and the support housing 11.

[0113] In specific implementation, the elastic layer can be foam, which can be adhered to the side wall of the outer ring 111; or, a groove can be opened on the side wall of the outer ring 111, and the elastic layer can be embedded in the groove of the side wall of the outer ring 111.

[0130] Referring to Figures 12 and 13, the support member 25 can be an annular structure with a gap on the outside of the first clamp 22, and it can be integrally formed on the top of the positioning part 221. The guide part 222 of the first clamp 22 protrudes from the support member 25. Referring to Figure 14, the bottom of the second clamp 24 is provided with a support part 245. The support part 245 can be an annular structure integrally formed on the bottom of the second clamp 24 and gapped on the outside of the guide part 222. The first snap-fit ​​member 243 is provided on the inner side of the support part 245, and the first protrusion 242 is provided on the outer side of the support part 245. The support part 245 can be detachably supported by the support member 25.

[0131] Referring to Figures 12-14, in order to improve the reliability of the assembly of the second clamp 24 and the first clamp 22, the turntable assembly of this disclosure may also include multiple connectors 26. The second clamp 24 and the connectors 26 can be detachably connected by screws or other components to further fix the second clamp 24 to the first clamp 22, thereby further fixing the turntable.

[0132] Referring to Figures 12 and 13, in a specific implementation, the connector 26 can be a columnar structure, integrally formed on the top of the positioning part 221. Both sides of the connector 26 are connected to the support member 25 and the first clamp 22 respectively, to further improve the reliability of the connector 26 on the positioning part 221. Bolt holes can be provided on the top of the connector 26. Referring to Figure 5, a connecting part 246 can be provided at the bottom of the second clamp 24. The connecting part 246 can be connected to multiple connectors 26 via bolts to achieve a detachable connection between the second clamp 24 and the connectors 26.

[0133] Referring to Figure 14, according to one embodiment of this disclosure, the connecting portion 246 may include multiple portions, which are spaced apart at the bottom of the second clamp 24. Each connecting portion 246 may be an integrally formed columnar structure on the bottom of the second clamp 24. The connecting portions 246 and the connecting members 26 are arranged in a one-to-one correspondence. Each connecting portion 246 is provided with a threaded through hole for connecting the corresponding connecting portion 246 to the connecting member 26 by bolts. According to another embodiment of this disclosure, the connecting portion 246 may also be a single structure provided on the bottom of the second clamp 24, that is, only one connecting portion 246 is provided. The connecting portion 246 may be an integrally formed ring-shaped structure on the bottom of the second clamp 24. The connecting portion 246 is provided with bolt through holes corresponding to the connecting members 26 for connecting the connecting portion 246 to the multiple connecting members 26 by bolts.

[0134] In some other embodiments, referring to FIG14, the two sides of the connecting portion 246 can be connected to the support portion 245 and the reinforcing rib 244 to improve the installation strength of the connecting portion 246.

[0135] It should be noted that the detachable connection between the connecting part 246 and the connecting member 26 is an optional feature. If the weight and size of the wheel 23 are relatively small, the detachable connection between the connecting part 246 and the connecting member 26 may not be necessary. If the weight and size of the wheel 23 are relatively large, the detachable connection between the connecting part 246 and the connecting member 26 may be provided to improve the assembly stability of the wheel 23.

[0136] The assembly of the support housing of the wheel assembly of this disclosure will be further described below with reference to Figures 11, 16-21.

[0137] Referring to Figure 11, the support housing 21 of this embodiment includes a first housing 212 and a second housing 213 that are detachably connected. Both the first housing 212 and the second housing 213 can be annular structures. When the first housing 212 and the second housing 213 are assembled, they can form a cylindrical receiving cavity 211. When the wheel assembly is assembled in the corresponding garment processing equipment, the wheel assembly is usually arranged horizontally or nearly horizontally. The second housing 213 is disposed above the first housing 212. The outer peripheral surface of the second housing 213 is provided with a toothed ring 2135 that matches the power component, so that the support housing 21 rotates with the wheel 22 under the drive of the power component. In other embodiments, the wheel assembly can also be arranged at an inclination in the horizontal direction, which is not limited here.

[0138] Figure 16 shows a schematic diagram of the structure of the first housing in Figure 11. Referring to Figure 16, a support portion 2121 is provided on the inner side of the first housing 212. The support portion 2121 and the positioning portion 221 are located at the same end of the receiving cavity 211. The support portion 2121 and the positioning portion 221 are configured as a bearing portion for loading the wheel 23.

[0139] Figure 17 shows a schematic diagram of the structure of the second housing in Figure 11. Referring to Figure 17, a holding portion 2131 is provided on the inner side of the second housing 213. The holding portion 2131 and the limiting portion 241 are located at the same end of the receiving cavity 211. The holding portion 2131 and the limiting portion 241 are configured to clamp the outer side of the circumferential surface of the wheel 23. The wheel 23 is disposed between the holding portion 2131 and the supporting portion 2121. In specific assembly, the wheel 23 can be first positioned on the supporting portion 2121 within the first housing 212, and then the second housing 213 can be connected to the first housing 212. This clamps the wheel 23 between the holding portion 2131 and the supporting portion 2121, thus positioning the wheel 23 within the receiving cavity 211.

[0140] Referring to Figures 16 and 17, according to one embodiment of this disclosure, the support portion 2121 can be an annular structure integrally formed on the bottom inner side of the first housing 212, and the holding portion 2131 can also be an annular structure integrally formed on the top inner side of the second housing 213. By placing the support portion 2121 at the bottom of the first housing 212 and the holding portion 2131 at the top of the second housing 213, the axial dimension of the wheel assembly 200 can be reduced, thereby reducing its space occupation. According to another embodiment of this disclosure, the support portion 121 can also be integrally formed on the middle inner side of the first housing 212, and the holding portion 2131 can be integrally formed on the middle inner side of the second housing 213.

[0141] To achieve a detachable connection between the first housing 212 and the second housing 213, the first housing 212 and the second housing 213 can be connected by a snap-fit ​​mechanism. The snap-fit ​​mechanism of the first housing 212 and the second housing 213 will be further explained below with reference to Figures 18-21.

[0142] Figure 18 shows an enlarged view of point I in Figure 17. Referring to Figure 18, the bottom of the second housing 213 is provided with multiple mounting slots 2132 at intervals. The openings of the mounting slots 2132 face the first housing 212, i.e., the openings of the mounting slots 2132 face downwards. Second latches 2133 are provided on the side walls of the mounting slots 2132. Figure 19 shows an enlarged view of point II in Figure 16. Referring to Figure 19, the top of the first housing 212 is provided with multiple second snap-fit ​​pieces 2122. Each second snap-fit ​​piece 2122 corresponds to a mounting slot 2132. Each second snap-fit ​​piece 2122 has a second snap-fit ​​portion 2123. The second snap-fit ​​piece 2122 can enter the corresponding mounting slot 2132 through its opening. The second snap-fit ​​portion 2123 on the second snap-fit ​​piece 2122 engages with the second latch 2133, forming the assembly state shown in Figure 20.

[0143] Referring to Figure 18, according to one embodiment of this disclosure, the second latch 2133 can be a protrusion provided on the side wall of the mounting groove 2132, and the inner side of the mounting groove 2132 can be open to facilitate the assembly of the second latching member 2122 within the mounting groove 2132. Referring to Figures 18-20, the second latching portion 2123 can be a hole-like structure. When the second housing 213 is placed on the first housing 212, the second latching portion 2123 is inserted into the corresponding mounting groove 2132, and the second latching portion 2123 on the second latching member 2122 is engaged with the second latch 2133. According to another embodiment of this disclosure, the second latching portion 2123 can also be a groove-like structure, with the opening of the groove-like structure facing the second latch 2133, allowing the second latch 2133 to enter the second latching portion 2123 through the opening of the groove-like structure.

[0144] Referring to Figure 18, according to one embodiment of the present disclosure, a second buckle 2133 may be provided on the side wall of the mounting groove 2132. According to another embodiment of the present disclosure, more second buckles 2133 may be provided on the side wall of the mounting groove 2132, such as two or three. When two second buckles 2133 are provided, the two second buckles 2133 may be provided on two opposite side walls of the mounting groove 2132. A second snap-fit ​​member 2122 that snaps into the second buckle 2133 may be assembled between the two second buckles 2133. The second snap-fit ​​portion 2123 on the second snap-fit ​​member 2122 has a hole-like structure. The two second buckles 2133 are snapped into the second snap-fit ​​member 2122 through the two openings of the hole-like structure, so that the two second buckles 2133 are connected by one second snap-fit ​​member 2122.

[0145] Referring to Figures 18 and 19, the bottom of the second housing 213 is provided with a positioning groove 2134, and the first housing 212 is provided with a positioning protrusion 2124. The positioning protrusion 2124 is inserted into the positioning groove 2134 to position the second housing 213 onto the first housing 212. During the process of positioning the second housing 213 onto the first housing 212, the second snap-fit ​​part 2123 is inserted into the corresponding mounting groove 2132, and the second snap-fit ​​part 2123 on the second snap-fit ​​member 2122 snaps onto the second buckle 2133 to fix the second housing 213 to the first housing 212.

[0146] Referring to Figures 18 and 19, according to one embodiment of the present disclosure, positioning grooves 2134 and mounting grooves 2132 are spaced apart on the same circumferential surface of the receiving cavity 211, and multiple positioning grooves 2134 and mounting grooves 2132 are spaced apart around the circumferential surface of the receiving cavity 211; correspondingly, positioning protrusions 2124 and second snap-fit ​​members 2122 are also spaced apart on the same circumferential surface of the receiving cavity 211, and multiple positioning protrusions 2124 and second snap-fit ​​members 2122 are spaced apart around the circumferential surface of the receiving cavity 211. The positioning groove 2134 and the corresponding positioning protrusion 2124 have relatively long circumferences, while the mounting groove 2132 and the second snap-fit ​​member 2122 have relatively short circumferences. This allows for differentiation between the positioning protrusion 2124 and the second snap-fit ​​member 2122. When the mounting groove 2132 on the second housing 213 is aligned with the second snap-fit ​​member 2122, pressing down on the second housing 213 allows the positioning protrusion 2124 and the second snap-fit ​​member 2122 to be simultaneously inserted into their corresponding positioning grooves 2134 and mounting grooves 2132. This method is convenient and quick, improving the assembly efficiency of the support housing 21. According to another embodiment of this disclosure, multiple positioning grooves 2134 and multiple positioning protrusions 2124 can be disposed on one circumference of the receiving cavity 211, while multiple mounting grooves 2132 and multiple second snap-fit ​​members 2122 are spaced apart on the other circumference of the receiving cavity 211. Under this condition, it is necessary to increase the radial dimensions of the first housing 212 and the second housing 213, which is an alternative solution.

[0147] Referring to Figure 19, according to one embodiment of this disclosure, a plurality of second protrusions 214 may be provided at intervals on the support portion 2121. At least a portion of the plurality of second protrusions 214 contacts the wheel 23 to reduce the contact area between the support portion 2121 and the wheel 23, thereby reducing the wear of the wheel 23 to a certain extent and improving the service life of the wheel 23. The part of the second protrusion 214 that contacts the wheel 23 may be arc-shaped. In some embodiments, the second protrusion 214 may be hemispherical so that the second protrusion 214 contacts the arc surface of the wheel 23. According to another embodiment of this disclosure, a plurality of second protrusions 214 may also be provided at intervals on the holding portion 2131 (as shown in Figure 21), or a plurality of second protrusions 214 that contact the wheel 23 may be provided at intervals on both the holding portion 2131 and the support portion 2121.

[0148] According to one embodiment of this disclosure, the first clamp 22 and the support housing 21 are separately disposed, that is, there is no connection between the first clamp 22 and the support housing 21, thereby eliminating the need for the retaining ribs for supporting the wheel 23 provided at the bottom of the first clamp 22 and the bottom of the support housing 21 in related technologies. This is because the retaining ribs require high temperature resistance of the material and will generate friction with the wheel 23. Separating the first clamp 22 and the support housing 21 can reduce the manufacturing cost of the retaining ribs and also improve the service life of the wheel 23. According to another embodiment of this disclosure, the retaining ribs in related technologies can also be provided between the first clamp 22 and the support housing 21.

[0149] The assembly process of the roulette wheel assembly provided in this disclosure is as follows: the middle part of the roulette wheel 23 is mounted to the outer side of the support member 25 to initially position the roulette wheel 23; then the second clamp 24 is assembled onto the first clamp 22 to clamp the roulette wheel 23 through the limiting part 241 of the second clamp 24 and the first clamp 22, so that the roulette wheel 23 is fixed on the first clamp 22; then the first housing 212 of the support housing 21 is assembled to the periphery of the roulette wheel 23, and the second housing 213 of the support housing 21 is assembled onto the first housing 212, thus completing the assembly of the roulette wheel assembly. The operation is simple, convenient and quick, and improves the assembly efficiency of the roulette wheel assembly.

[0150] As shown in Figures 22 and 23, in some embodiments, the turntable assembly 200 further includes: a center member 27 and a support rib 28; the support housing 21 is provided with an outer ring 215; the center member 27 is disposed at the center of the support housing 21; the support rib 28 is connected between the outer peripheral surface of the center member 27 and the inner peripheral surface of the outer ring 215; the radial directions of the support rib 28 and the outer ring 215 have an included angle; and the wheel 23 is mounted on the support rib 28.

[0151] The support rib 28 connects the outer peripheral surface of the center component 27 and the inner peripheral surface of the outer ring 215. The support rib 28 is roughly elongated. The radial direction of the support rib 28 and the outer ring 215 is at an angle, indicating that the extension direction of the support rib 28 is different from that of the outer ring 215. During the rotation of the turntable assembly, the support rib 28 will gradually come into contact with the partition rib on the housing of the moisture absorption and desiccation module, thereby reducing the contact area between the support rib 28 and the partition rib.
