[0055] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. The following description is only for the purpose of illustrating the basic principles of the present invention and is not intended to limit the present invention.

[0056] In clothes handling appliances like dryers and washer-dryers, moisture inside the clothing container is converted into dry air by a drying module, which then re-enters the clothing container, creating an airflow cycle. This section describes the drying module using a washer-dryer as an example.

[0057] A washer-dryer includes a clothing container for loading clothes and a drying module. The clothing container is equipped with an air inlet and an air outlet. The drying module includes a housing, within which a motor and a moisture-absorbing wheel are housed. A distance is provided between the wheel and the two end surfaces of the housing to form an air inlet and an air outlet. The air inlet communicates with the air outlet of the clothing container, while the air outlet communicates with the air inlet of the clothing container. The motor drives the wheel to rotate within the housing. In drying mode, moisture from the clothing container is transported to the air inlet, forming a humid airflow. The humid airflow enters the rotatable wheel, where it is absorbed and converted into dry airflow. The dry airflow is then transported through the exhaust duct to the clothing container, and this cycle continues until the desired drying effect is achieved.

[0058] Example 1:

[0059] During the transportation and assembly of the drying module, the wheel may move inside the shell (including but not limited to vibration / falling, etc.), causing the wheel to collide with the shell of the drying module and cause damage, which is not conducive to the assembly and use of the drying module.

[0060] Based on the above technical problems, the present disclosure provides a drying module to facilitate the assembly and use of the drying module to a certain extent.

[0061] FIG1 shows a cross-sectional schematic diagram of a drying module according to some embodiments of the present disclosure, FIG2 shows an enlarged schematic diagram of point A in FIG1 , FIG3 shows a structural schematic diagram of the first housing in FIG1 , and FIG4 shows a schematic diagram of the assembly of the buffer assembly in FIG3 on the first housing. In conjunction with FIG1 to FIG4 , the drying module 1 includes a housing 100, a wheel 200, and a buffer assembly 1100, wherein the wheel 200 is rotatably disposed within the housing 100, the buffer assembly 1100 is disposed on at least one inner wall of the housing 100 facing the wheel 200, the buffer assembly 1100 includes a connector 1101 and a contact member 1102, one end of the connector 1101 is connected to the inner wall of the housing 100, the contact member 1102 is disposed at an end of the connector 1101 away from the inner wall of the housing 100, the contact member 1102 is in contact with the end face of the wheel 200, and at least one of the connector 1101 and the contact member 1102 is elastic.

[0062] The drying module 1 provided in the present disclosure has a buffer assembly 1100 provided in the shell 100 of the drying module 1, and the buffer assembly 1100 includes a connector 1101 and a contact member 1102. One end of the connector 1101 is connected to the inner wall of the shell 100, and the contact member 1102 is provided at the end of the connector 1101 away from the inner wall of the shell 100. The contact member 1102 contacts the end face of the wheel 200, and the contact member 1102 can limit the movement of the wheel 200 in the shell 100. Since at least one of the connector 1101 and the contact member 1102 is elastic, the contact between the buffer assembly 1100 and the wheel 200 can be flexible, thereby avoiding the phenomenon of collision and damage between the wheel 200 and the shell 100 during transportation and assembly of the drying module 1.

[0063] FIG5 is a schematic structural diagram of the second housing in FIG1 . In conjunction with FIG1 , FIG3 , and FIG5 , housing 100 includes a first housing 101 and a second housing 102 connected to each other. First housing 101 is provided with a first accommodating chamber 104, and second housing 102 is provided with a second accommodating chamber 105. When first housing 101 and second housing 102 are assembled, first accommodating chamber 104 and second accommodating chamber 105 cooperate to form an accommodating chamber for loading wheel disc 200, within which wheel disc 200 is rotatably disposed. Wheel disc 200 can be made of a material with good moisture absorption and desorption properties, such as zeolite, lithium chloride, silica gel, modified silica gel, or 13X (sodium X-type) molecular sieve.

[0064] Due to the characteristics of the material used to make the wheel disc 200, the wheel disc 200 is relatively brittle. Therefore, during assembly and transportation of the drying module 1, the wheel disc 200 is susceptible to breakage due to vibrations, falls, and other movements. The buffer assembly 1100 provided within the housing 100 of the present disclosure is in flexible contact with the end surface of the wheel disc 200, thereby preventing the wheel disc 200 from breaking to a certain extent.

[0065] In some embodiments, at least a portion of the connector 1101 is elastic, and the contact member 1102 is a rigid member. Although the contact member 1102 is in rigid contact with the wheel disc 200, at least a portion of the connector 1101 is elastic. Therefore, when the wheel disc 200 moves, the wheel disc 200 causes the connector 1101 to deform through the contact member 1102 to accommodate the movement of the wheel disc 200. When the wheel disc 200 returns to its initial position, the connector 1101 also recovers its deformation accordingly.

[0066] In some embodiments, the end faces of the contact member 1102 and the wheel disc 200 are in point contact, which can reduce the contact area between the contact member 1102 and the wheel disc 200, thereby reducing the friction on the wheel disc 200 and allowing the wheel disc 200 to rotate smoothly. In addition, it can also reduce damage to the wheel disc 200 and has good practicality.

[0067] In a specific implementation, the side of the contact member 1102 facing the wheel disc 200 is arc-shaped, so that the contact member 1102 and the wheel disc 200 are in point contact. The contact member 1102 can be spherical or hemispherical, etc., without limitation. It is sufficient to ensure that the contact member 1102 and the wheel disc 200 are in point contact.

[0068] In some other embodiments, the contact member 1102 may also be in line contact or surface contact with the wheel 200, which is not limited here.

[0069] In conjunction with Figures 2 and 4 , in some embodiments, contact member 1102 may be a steel ball, and connector 1101 may be a spring, etc. Of course, contact member 1102 may also be a ball made of other materials, and connector 1101 may also be an elastic member made of other materials, such as a gasket made of an elastic material, without limitation. When connector 1101 is a spring, contact member 1102 can be snapped into the end of connector 1101 to facilitate assembly of contact member 1102 and connector 1101, providing convenient and practical solutions.

[0070] It should be noted that the connecting member 1101 may be only partially elastic, or have elasticity in two or more sections, or be elastic as a whole, etc., and there is no limitation here.

[0071] 2 and 4 , in some embodiments, the buffer assembly 1100 further includes a stopper 1103 disposed on the inner wall of the housing 100. The connector 1101 deforms within the stopper 1103, and the contact member 1102 includes a contact portion that protrudes from the stopper 1103 and contacts the end surface of the wheel disc 200. The stopper 1103 can limit deformation of the connector 1101, preventing buffer failure caused by the connector 1101 failing to return to its original position in a timely manner.

[0072] In combination with Figures 2 and 4, in some embodiments, the limiting member 1103 may include a first limiting groove 130 arranged on the inner wall of the shell 100, one end of the connecting member 1101 is arranged at the bottom of the first limiting groove 130, and the other end of the connecting member 1101 is assembled with the above-mentioned contact member 1102.

[0073] In a specific implementation, in combination with Figures 2 and 4, a support portion 129 can be provided on the inner wall of the housing 100. The support portion 129 can correspond to the rotation axis of the wheel disc 200, and the first limiting groove 130 can be provided on the support portion 129.

[0074] In some other embodiments, the limiting member 1103 can also be a limiting protrusion arranged on the inner wall of the shell 100, and a limiting hole can be opened on the limiting protrusion, that is, the connecting member 1101 is arranged in the limiting hole, one end of the connecting member 1101 is connected to the limiting protrusion, and the other end of the connecting member 1101 is assembled with the above-mentioned contact member 1102; or, the limiting member 1103 is a combination of the first limiting groove 130 and the limiting protrusion, that is, the first limiting groove 130 is connected to the limiting hole, one end of the connecting member 1101 is connected to the bottom of the first limiting groove 130, and the other end of the connecting member 1101 passes through the first limiting groove 130 in sequence and is located in the limiting hole, and the other end of the connecting member 1101 is assembled with the above-mentioned contact member 1102.

[0075] When a limiting member 1103 is provided, one end of the connecting member 1101 can be connected to the bottom of the limiting member 1103 or can be directly pressed against the bottom of the limiting member 1103, and the assembly of the connecting member 1101 in the limiting member 1103 is achieved by the extrusion of the wheel 200.

[0076] In other embodiments, the connector 1101 may be rigid, and at least a portion of the contact member 1102 may be elastic. When the wheel 200 moves, the wheel 200 compresses the contact member 1102 to directly deform to accommodate the movement of the wheel 200. When the wheel 200 returns to its initial position, the contact member 1102 also recovers its deformation accordingly. Under such operating conditions, the portion where the contact member 1102 contacts the end face of the wheel 200 is elastic. Of course, other portions of the contact member 1102 may also be elastic, or the contact member 1102 may have two or more sections of elasticity, or the contact member 1102 may be elastic as a whole, without limitation.

[0077] In some other embodiments, at least portions of the connector 1101 and the contact member 1102 are elastic. When the wheel 200 moves, the wheel 200 compresses the contact member 1102 and the connector 1101 to deform to accommodate the movement of the wheel 200. When the wheel 200 returns to its initial position, the contact member 1102 and the connector 1101 also recover their deformation accordingly. Under such operating conditions, the contact member 1102 and the connector 1101 can each have a section of elasticity. Of course, the contact member 1102 and the connector 1101 can also have more than two sections of elasticity, or the contact member 1102 and the connector 1101 can be elastic as a whole, etc., without limitation here.

[0078] 3 , a plurality of buffer assemblies 1100 may be provided, and the plurality of buffer assemblies 1100 may be spaced apart around the rotation axis of the wheel disc 200 , thereby providing a more uniform buffering effect on the wheel disc 200 to prevent the wheel disc 200 from being damaged due to the movement of the wheel disc 200 colliding with the shell 100 .

[0079] As described above, the housing 100 includes a first housing 101 and a second housing 102, which are connected. The first housing 101 is generally located above the second housing 102. The buffer assembly 1100 can be disposed on the first housing 101. To prevent the second housing 102 from contacting the wheel 200, foam is typically disposed on the second housing 102 to provide a cushioning support. However, after long-term use, the foam will wear out and become ineffective, failing to provide a cushioning support function.

[0080] FIG6 shows a schematic diagram of the assembly of the support member in FIG5 on the second shell. In combination with FIG5 and FIG6, the present disclosure provides a support member 1104 in the second shell 102. The support member 1104 can be made of a rigid material, preferably a material with self-lubricating function, to improve the smoothness of the rotation of the wheel 200. The support member 1104 is arranged on the outside of the rotating shaft and only plays a supporting role. Since the support member 1104 is made of a rigid material, it can avoid the technical problem of the foam in the related art that wears out after long-term use, so as to effectively support the wheel 200. The buffer assembly 1100 can achieve buffering of the wheel 200 to prevent the wheel 200 from being damaged during assembly and transportation.

[0081] 5 and 6 , the support member 1104 can be annular and coaxially disposed outside the rotation axis of the wheel disc 200. Furthermore, the support member 1104 can be integrally formed on the second housing 102. The support member 1104 and the second rotation axis 132 can be connected via a plurality of connecting ribs 1105. The plurality of connecting ribs 1105 are radially arranged around the rotation axis of the wheel disc 200 to enhance the reliability of the assembly between the support member 1104 and the second housing 102. Furthermore, the plurality of connecting ribs 1105 can also be integrally formed on the second housing 102 to further enhance the connection strength of the support member 1104 to the second housing 102.

[0082] 2 , a first rotating shaft 131 is provided in the first shell 101, and a second rotating shaft 132 may be provided in the second shell 102. The first rotating shaft 131 and the second rotating shaft 132 are connected to form a rotating shaft for the wheel disc 200 to rotate. The wheel disc 200 is provided with a center hole, and a sleeve 1106 is provided in the center hole. The sleeve 1106 is rotatably connected to the rotating shaft, so that the wheel disc 200 can rotate around the rotating shaft under the drive of the driving assembly.

[0083] In some embodiments, the first rotating shaft 131 and the second rotating shaft 132 can be assembled by docking. After the first rotating shaft 131 and the second rotating shaft 132 are docked, they can be fixedly connected by bolts. In other embodiments, the first rotating shaft 131 and the second rotating shaft 132 can be fixedly assembled by interference fit, snap fit, or other connection methods, which are not limited here.

[0084] 2 , the contact member 1102 of the buffer assembly 1100 and the sleeve 1106 are in contact with the end portion facing the first shell 101, while at least a portion of the support member 1104 and the sleeve 1106 are in contact with the end portion facing the second shell 102, thereby ensuring the supporting effect of the support member 1104 on the wheel disc 200 while ensuring the buffering effect of the buffer assembly 1100 on the wheel disc 200.

[0085] 2 , in some embodiments, the sleeve 1106 is provided with flaps at two opposing ends. Both flaps extend radially along the wheel disc 200 to the ends of the wheel disc 200. The two flaps are a first flap 1101 facing the first shell 101 and a second flap 1102 facing the second shell 102. Because at least a portion of the buffer assembly 1100 is elastic, the contact member 1102 of the buffer assembly 1100 is in full contact with the first flap 1101 to ensure the buffering effect of the buffer assembly 1100 on the wheel disc 200. The support member 1104 is rigid and can partially contact the second flap 1102, as shown in the figure. In other embodiments, the support member 1104 can also be in full contact with the second flap 1102, which is not a limitation here.

[0086] It should be noted that the above-mentioned buffer assembly 1100 can also be provided in the second shell 102, but since the second shell 102 is provided below the first shell 100, the buffer assembly 1100 provided on the second shell 102 needs to bear a larger deadweight, which is not conducive to the deformation recovery of the buffer assembly 1100 on the second shell 102. Therefore, the buffer assembly is only provided in the first shell 101 located above, and a rigid support member 1104 is provided in the second shell 102 located below.

[0087] Based on the above-mentioned drying module 1 , the present disclosure further provides an electrical device, which includes the above-mentioned drying module 1 .

[0088] The electrical equipment provided by the present disclosure has a buffer assembly 1100 provided in the shell 100 of the drying module 1, and the buffer assembly 1100 includes a connector 1101 and a contact 1102. One end of the connector 1101 is connected to the inner wall of the shell 100, and the contact 1102 is provided at the other end of the connector 1101. The contact 1102 contacts the end face of the wheel 200, and the contact 1102 can limit the movement of the wheel 200 in the shell 100. Since at least one of the connector 1101 and the contact 1102 is elastic, the contact between the buffer assembly 1100 and the wheel 200 can be flexible, thereby avoiding the phenomenon of damage caused by collision between the wheel 200 and the shell 100 during transportation and assembly of the drying module 1, and having good practicality.

[0089] Figure 7 shows a schematic diagram of the structure of an electrical appliance equipped with the drying module shown in Figure 1. In conjunction with Figure 7, the electrical appliance provided by the present disclosure can be a dryer or a washer-dryer. In a specific implementation, the drying module 1 is connected to the air outlet and air inlet of the clothing container R, respectively. Thus, the drying module 1 and the clothing container R form a circulation path, thereby drying the hot and humid air circulating therein.

[0090] In other embodiments, the drying module may also be included in various electrical appliances requiring dehumidification, such as a dehumidifier and a dishwasher, and is not limited here.

[0091] Example 2:

In conjunction with Figures 8-13, the drying module includes a housing 100, with a second limiting groove 103 for loading the gear assembly provided on the inner side of the housing 100, and a lubricating layer 127 provided on the circumferential inner wall of the second limiting groove 103.

[0093] The drying module provided by the present disclosure has a second limiting groove 103 provided on the end face of the shell 100, so that the gear assembly can be assembled in the second limiting groove 103 to limit the radial swing of the gear assembly, thereby eliminating the limiting parts such as the shaft sleeve used to limit the swing of the gear assembly to reduce production costs, and correspondingly, the assembly process of the shaft sleeve in the shell 100 can also be reduced; in addition, since a lubricating layer 127 is provided on the circumferential inner wall of the second limiting groove 103, the gear assembly can rotate smoothly in the second limiting groove 103, which has good practicality.

[0094] In conjunction with Figure 9, the shell 100 may include a first shell 101 and a second shell 102 connected to each other. The first shell 101 is provided with a first accommodating cavity 104, and the second shell 102 is provided with a second accommodating cavity 105. The first accommodating cavity 104 and the second accommodating cavity 105 cooperate to form an accommodating cavity for loading the wheel 200. The wheel 200 is rotatably arranged in the accommodating cavity. The first shell 101 can be located above the second shell 102. The space between the wheel 200 and the first shell 101 can be set as an air inlet channel, and the space between the wheel 200 and the second shell 102 can be set as an air outlet channel. This is the existing technology and will not be elaborated here.

[0095] 10-13 , in actual implementation, the gear 400 includes a gear shaft 401, which is drivingly connected to the drive shaft 301 of the motor 300. The gear shaft 401 includes a stopper 402 protruding from the end of the gear 400. The stopper 402 of the gear shaft 401 is loosely fitted within the second stopper slot 103. The second stopper slot 103 limits radial swing of the stopper 402 of the gear shaft 401, thereby limiting radial swing of the gear 400. The circumference of the gear 400 contacts the periphery of the wheel disc 200, driving the wheel disc 200 to rotate.

[0096] In other embodiments, part of the circumferential surface clearance of the gear 400 can also be assembled in the second limiting groove 103, and the remaining circumferential surface of the gear 400 is in contact with the periphery of the wheel disc 200, which can also achieve the limitation of the radial swing of the gear assembly.

[0097] 13 , a motor accommodating portion 106 is provided on the end face of the second shell 102, and the motor accommodating portion 106 is provided on the outside of the second accommodating cavity 105. The motor 300 for driving the gear 400 to rotate is provided in the motor accommodating portion 106. The output end of the motor 300 is connected to the drive shaft 301, and the gear shaft 401 of the gear 400 can be fixedly connected to the drive shaft 301. In this way, the motor 300 can drive the gear 400 to rotate, thereby driving the wheel 200 to rotate in the accommodating cavity. The second limiting groove 103 is provided on the outside of the first accommodating cavity 104 of the first housing 101, which is located above the motor accommodating portion 106. The limiting portion 401 of the gear shaft 401 is provided with a clearance in the second limiting groove 103, so that the gear 400 can rotate normally within the set swing range. During the rotation of the gear 400, the gear 400 will contact the circumferential inner wall of the second limiting groove 103. In order to ensure smooth rotation of the gear 400, a lubricating layer 127 can be provided on the circumferential inner wall of the second limiting groove 103. In a specific implementation, the lubricating layer can be provided only on the circumferential inner wall of the second limiting groove 103 by attaching or applying. The lubricating layer can be made of a soft metal material. Alternatively, the first housing 101 can be made of a self-lubricating material as a whole. The self-lubricating material can be a mixture of nylon and glass fiber or a polymer-based, ceramic-based material. Accordingly, the circumferential inner wall of the second limiting groove 103 also has a self-lubricating function, so that the gear 400 can rotate smoothly in the second limiting groove 103.

[0098] It should be noted that the entire second shell 102 can also be made of self-lubricating material, which is not limited here.

[0099] 10-12 , a first protrusion 107 is provided on the inner side of the first housing 101, and the second limiting groove 103 is provided on the first protrusion 107. The first protrusion 107 can be integrally formed on the first housing 101. The first protrusion 107 can be cylindrical. In other embodiments, the first protrusion 107 can also be square, frustum-shaped, or other shapes, which are not limited here.

[0100] 10-12 , a recessed portion 108 may be provided on the inner side of the first housing 101, and the first protrusion 107 may be integrally formed with the recessed portion 108. The recessed portion 108 allows for a sufficient distance between the first protrusion 107 and the motor housing 106 to facilitate assembly of the gear 400 and rolling contact between the gear 400 and the periphery of the wheel disc 200. The recessed portion 108 is also generally cylindrical, but may also have other shapes, such as a square or a frustum, without limitation.

[0101] 4 , part of the periphery of the first protrusion 107 may be connected to the side wall of the recess 108 , which can improve the connection strength between the first protrusion 107 and the first housing 101 and ensure the reliability of the gear 400 rotating in the second limiting groove 103 .

[0102] 10-12 , a distance may be provided between the periphery of another portion of the first protrusion 107 and the sidewall of the recess 108. The first protrusion 107 and the sidewall of the recess 108 may be connected by a plurality of spaced-apart first reinforcing ribs 109, thereby further enhancing the connection strength of the first protrusion 107 within the housing 100 and ensuring the reliable rotation of the gear 400 within the second limiting groove 103. The first reinforcing rib 109 may be integrally formed with the first protrusion 107 on the bottom of the recess 108. The plurality of first reinforcing ribs 109 may be radially arranged at intervals around the circumference of the first protrusion 107 to enhance the reliability of the connection between the first reinforcing ribs 109 and the first protrusion 107 on the first housing 101.

[0103] It should be noted that the second limiting groove 103 can also be directly opened on the end face of the first shell 101, that is, the end face of the first shell 101 is not recessed at the place where the second limiting groove 103 is opened. In this case, the thickness of the part of the first shell 101 where the second limiting groove 103 is set will be thicker, which is not conducive to ensuring the flatness of the inner end face of the first shell 101 during molding. The recessed treatment at the position where the second limiting groove 103 is set in the first shell 101 can reduce the thickness of this part of the first shell 101, so that the inner end face of the first shell 101 is as flat as possible during molding.

[0104] In addition, in conjunction with Figure 13, a through hole 110 can be provided on the second limiting groove 103, and the through hole 110 can be provided at the bottom of the second limiting groove 103. The internal conditions of the shell 100 can be intuitively observed through the through hole 110, especially for observing the operation of the motor 300 and / or the gear 400, including but not limited to the speed of the motor 300 and / or the gear 400, the wear condition of the gear 400, etc.

[0105] 13 , the drying module further includes a seal 500, which is detachably connected to the through hole 110. When it is necessary to observe the interior of the shell 100, the seal 500 can be removed to facilitate observation of the interior of the shell 100. After the observation is completed, the seal 500 is assembled in the observation hole 110 to enable the device to operate normally, thereby preventing airflow from leaking from the observation hole 110 when the device is running.

[0106] In a specific implementation, the sealing member 500 may be a blocking block, which may be connected to the observation hole 110 by means of threads or interference fit to facilitate disassembly of the sealing member 500 .

[0107] In conjunction with Figure 10, a first support portion 111 for limiting the movement of the wheel disc 200 is provided in the first accommodating cavity 104 of the first shell 101. The first support portion 111 is used to assist the rotation of the wheel disc 200. The first support portion 111 can be partially annular or roughly annular. The outer wall of the first support portion 111 is connected to the circumferential inner wall of the first accommodating cavity 104. There is a gap between the periphery of the wheel disc 200 and the circumferential inner wall of the first accommodating cavity 104. The projection of the periphery of the wheel disc 200 falls on the first support portion 111. In order to enable the gear 400 to drive the wheel disc 200, the depth of the second limiting groove 103 (i.e., the height of the first protrusion 107) can be less than or equal to the height of the first support portion 111. Preferably, the depth of the second limiting groove 103 is consistent with the height of the first support portion 111, i.e., the notch of the second limiting groove 103 and the first support portion 111 are located in the same plane. In this way, the first protrusion 107 and the first support portion 111 are located in the same plane to avoid interference with the rotation of the wheel disc 200. Part of the periphery of the first protrusion 107 is connected to the outside of the first support portion 111.

[0108] 10 to 12 , when the motor 300 drives the gear 400 to rotate the wheel 200, the wheel 200 may generate friction with the first support portion 111, which will affect the normal operation of the wheel 200 on the one hand, and generate noise on the other hand. Based on this, the present invention provides one or more shock-absorbing members 600 at intervals on the first support portion 111, so that when the wheel 200 rotates, the wheel 200 will contact the shock-absorbing members 600. Since the shock-absorbing members 600 are arranged at intervals, the contact area between the wheel 200 and the first support portion 111 can be reduced, thereby reducing the vibration and noise of the housing 100 when the wheel 200 rotates.

[0109] 10-12 , in a specific implementation, shock-absorbing mounting portions 700 may be spaced apart on the first support portion 111, and the shock-absorbing mounting portions 700 and the shock-absorbing members 600 are provided correspondingly, and the shock-absorbing members 600 are provided in the corresponding shock-absorbing mounting portions 700, and the shock-absorbing members 600 at least partially protrude from the plane where the corresponding shock-absorbing mounting portions 700 are located to form a shock-absorbing portion. When the wheel 200 rotates, the shock-absorbing portion of the shock-absorbing member 600 protruding from the plane where the shock-absorbing mounting portions 700 are located is in direct contact with the wheel 200, so as to reduce the vibration and noise of the shell 100 when the wheel 200 rotates.

[0110] In addition, in order to improve the reliability of the installation of the shock absorber 600, adhesive can be applied between the shock absorber 600 and the first support part 111 and between the shock absorber 600 and the corresponding shock absorber mounting part 700, and then the shock absorber 600 can be fixed in the corresponding shock absorber mounting part 700 by bonding.

[0111] 11 , in some embodiments, the shock-absorbing mounting portion 700 can be a shock-absorbing frame provided on the first support portion 111. The shock-absorbing frame can be fixed to the first support portion 111 in an integrally formed manner, and the shock-absorbing member 600 can be interference-fitted into the corresponding shock-absorbing frame. Of course, in other embodiments, a groove can be provided on the first support portion 111, and the shock-absorbing member 600 can be assembled into the corresponding groove, or the shock-absorbing member 600 can be directly bonded to the first support portion 111, without limitation herein.

[0112] Based on the above-mentioned drying module, the present disclosure also provides a clothing processing device, which includes the above-mentioned drying module.

[0113] The clothing processing device having the above-mentioned drying module, since the radial swing of the gear assembly is limited by setting a second limiting groove 103 on the end face of the shell 100, the limiting member used to limit the swing of the gear assembly can be eliminated, thereby reducing production costs and correspondingly reducing the assembly process; in addition, since a lubricating layer is provided on the circumferential inner wall of the second limiting groove 103, the gear assembly can rotate smoothly in the second limiting groove 103, which has good practicality.

[0114] The clothing processing device may be a clothes dryer or a washer-dryer. Of course, the drying module therein may also be applied to various devices requiring dehumidification, such as dehumidifiers and dishwashers.

[0115] Example 3:

[0116] 10 to 12 , in the first embodiment, a shock absorber 600 is provided on the first support portion 111 to reduce friction and vibration between the wheel disc 200 and the first support portion 111 . However, the shock absorber 600 and the wheel disc 200 are in sliding friction, resulting in a large friction force, which affects the smooth rotation of the wheel disc 200 .

[0117] Based on the above technical problems, the present disclosure provides a drying module and a clothes processing device to improve the friction force of the wheel 200 during rotation to a certain extent, so that the wheel 200 can rotate smoothly.

[0118] Figure 15 shows a top view of a first shell provided with a shock-absorbing wheel. In conjunction with Figure 15, the drying module includes a shell 100 and a wheel disc 200. The wheel disc 200 is rotatably arranged in the shell 100. A plurality of shock-absorbing wheels 800 are arranged on the inside of the shell 100. The shock-absorbing wheels 800 are rotatably connected in the shell 100, and the circumferential surface of the shock-absorbing wheel 800 is in rolling contact with the wheel disc 200.

[0119] The drying module provided by the present disclosure has multiple shock-absorbing wheels 800 arranged on the inner side of the shell 100. The shock-absorbing wheels 800 are rotatably connected to the shell 100, and the circumferential surface of the shock-absorbing wheels 800 is in rolling contact with the wheel disc 200. In this way, the sliding friction in the related art can be changed to rolling friction, so as to reduce and improve the friction force when the wheel disc 200 rotates, so that the wheel disc 200 rotates smoothly.

[0120] It should be noted that when the shock-absorbing wheel 800 is installed, a certain installation gap is maintained between the shock-absorbing wheel 800 and the wheel disc 200, and the circumference of the shock-absorbing wheel 800 is in contact with the wheel disc 200 for at least part of the time.

[0121] As described above, in combination with Figure 9, the shell 100 includes a first shell 101 and a second shell 102 connected to each other. The first shell 101 is provided with a first accommodating cavity 104, and the second shell 102 is provided with a second accommodating cavity 105. When the first shell 101 and the second shell 102 are assembled, the first accommodating cavity 104 and the second accommodating cavity 105 cooperate to form an accommodating cavity for loading the wheel 200. The wheel 200 is rotatably arranged in the accommodating cavity. The first shell 101 can be located above the second shell 102. The area between the end faces of the wheel 200 and the first shell 101 is set as an air inlet channel, and the area between the end faces of the wheel 200 and the second shell 102 is set as an air outlet channel. This is the existing technology and will not be elaborated here.

[0122] Figure 16 shows a schematic diagram of the specific arrangement of the shock-absorbing wheel in Figure 15. In combination with Figure 15 and Figure 16, during specific implementation, a mounting cavity 112 corresponding to the shock-absorbing wheel 800 can be provided in the shell 100, and the mounting cavity 112 is provided with an opening. The opening of the mounting cavity 112 faces the wheel disc 200, and the shock-absorbing wheel 800 is arranged in the mounting cavity 112. The shock-absorbing wheel shaft 801 of the shock-absorbing wheel 800 is provided on the side wall of the mounting cavity 112. The shock-absorbing wheel 800 at least partially protrudes from the plane where the opening of the mounting cavity 112 is located. When the wheel disc 200 rotates, the circumferential surface of the shock-absorbing wheel 800 can contact the wheel disc 200, so that the shock-absorbing wheel 800 and the wheel disc 200 form rolling friction, so that the wheel disc 200 can rotate smoothly under the premise of effectively supporting and damping the wheel disc 200.

[0123] In some embodiments, the circumference of the shock-absorbing wheel 800 has a certain elasticity, or the shock-absorbing wheel 800 itself is made of elastic material to adapt to the swing of the wheel disc 200 during rotation. The axial direction of the shock-absorbing wheel 800 can be set along the wheel disc 200 or close to the radial direction of the wheel disc 200, so that multiple shock-absorbing wheels 800 are radially arranged around the central axis of the wheel disc 200 to further reduce the friction between the shock-absorbing wheel 800 and the wheel disc 200, so that the wheel disc 200 rotates smoothly.

[0124] In conjunction with Figure 16, in some embodiments, the shock-absorbing wheel 800 can be fixedly connected to the shock-absorbing wheel shaft 801, and the two ends of the shock-absorbing wheel shaft 801 can be rotatably connected to the side walls of the installation cavity 112. When the wheel disc 200 and the shock-absorbing wheel 800 come into contact, the wheel disc 200 drives the shock-absorbing wheel 800 to rotate, and the shock-absorbing wheel shaft 801 of the shock-absorbing wheel 800 rotates on the side walls of the installation cavity 112, thereby realizing the driven rotation of the shock-absorbing wheel 800.

[0125] In some embodiments, the damping wheel 800 and the damping wheel shaft 801 are preferably integrally formed to improve the reliability of the two during use and improve assembly efficiency. Of course, in other embodiments, the damping wheel 800 can also be fixedly connected to the damping wheel shaft 801 using a key connection or other methods, which is not limited here.

[0126] FIG17 shows a front view of FIG16 . In conjunction with FIG16 and FIG17 , the mounting cavity 112 is square or substantially square in shape, with the ends of the shock-absorbing axle 801 rotatably connected to two opposing sidewalls of the mounting cavity 112. A first mounting hole 113 is provided on the sidewall of the mounting cavity 112. The first mounting hole 113 extends from the opening of the mounting cavity 112 away from the wheel disc 200. The first mounting hole 113 includes a first hole 1132 and a second hole 1133, which are sequentially connected to the opening. The shock-absorbing axle 801 and the first hole 1132 have at least a partial interference fit, and the shock-absorbing axle 801 is disposed within the second hole 1133 with a clearance fit. In practice, the shock-absorbing axle 801 can be placed at the opening of the mounting cavity 112 and then pressed downward, causing the end of the shock-absorbing axle 801 to pass through the first hole 1132 at the same end and enter the second hole 1133 at the same end. Because the shock-absorbing wheel shaft 801 is disposed in the second hole 1133 with a clearance fit, the rotating shock-absorbing wheel 800 can drive the shock-absorbing wheel shaft 801 to rotate in the second hole 1133 under the drive of an external force. Due to the interference fit between the shock-absorbing wheel shaft 801 and the first hole 1132, the shock-absorbing wheel shaft can be restricted from entering the second hole 1133 from the first hole 1132, thereby preventing the shock-absorbing wheel shaft 801 from escaping from the corresponding installation cavity 112, so that the shock-absorbing wheel shaft 801 and the shock-absorbing wheel 800 can rotate normally. In some embodiments, the interference fit and the clearance fit can be achieved by designing the diameter of the shock-absorbing wheel shaft 801 to be H, which is larger than the diameter of the portion of the first hole 1132 that fits the shock-absorbing wheel shaft 801, and smaller than the diameter of the portion of the second hole 1133 that fits the shock-absorbing wheel shaft 801.

[0127] Since the shock-absorbing wheel set E consisting of the shock-absorbing wheel shaft 801 and the shock-absorbing wheel 800 can be assembled into place only by pressing down, the assembly efficiency of the shock-absorbing wheel set E can be improved, and the device has good practicality.

[0128] In combination with Figures 16 and 17, in some embodiments, the second hole body 1133 can be arc-shaped so that the shock-absorbing wheel shaft 801 can rotate in the second hole body 1133, and the first hole body 1132 has at least a hole diameter smaller than the diameter of the second hole body 1133, so that the shock-absorbing wheel shaft 801 can rotate in the second hole body 1133 but cannot escape through the second hole body 1132.

[0129] 16 and 17 , the first hole body 1132 may be rectangular, the aperture of the first hole body 1132 needs to be smaller than the diameter of the third hole body 1133, and the central angle of the second hole body 1132 needs to be greater than 180°, so that the end of the shock-absorbing wheel shaft 801 can be passed through the first hole body 1132 by pressing down, and the shock-absorbing wheel shaft 801 can be rotated in the second hole body 1133, but cannot escape through the first hole body 11323, so as to achieve the limitation of the shock-absorbing wheel shaft 801 in the direction parallel to the central axis of the wheel disc 200.

[0130] In other embodiments, the first hole body 1132 may be partially rectangular, and the aperture of this portion may be smaller than the diameter of the second hole body 1133 to prevent the vibration-damping wheel shaft 801 from escaping from the first hole body 1132, and the remaining portion of the first hole body 1132 may be arc-shaped or trapezoidal, etc., which is not limited here.

[0131] In addition, in combination with Figures 16 and 17, the first mounting hole 113 can also include a first guide hole 1131. The first guide hole 1131 is arranged between the first hole body 1132 and the opening of the mounting cavity 112, that is, the two are transitioned through the first guide hole 1131. The hole spacing of the first guide hole 1131 on the side close to the opening of the mounting cavity 112 is greater than the hole spacing on the side close to the first hole body 1132. When the vibration-damping wheel shaft 801 needs to be assembled, the vibration-damping wheel shaft 801 with the vibration-damping wheel 800 can be placed in the first guide hole 1131. Since the vibration-damping wheel shaft 801 and the first hole body 1132 have an interference fit, the vibration-damping wheel shaft 801 is supported in the first guide hole 1131 of the first mounting hole 113, and the initial positioning of the vibration-damping wheel shaft 801 can be achieved. The vibration-damping wheel shaft 801 is then pressed down by external force so that the vibration-damping wheel shaft 801 passes through the first hole body 1132 and is assembled in the second hole body 1133.

[0132] In some embodiments, the hole pitch of the first guide hole 1131 gradually decreases from the opening of the mounting cavity 112 toward the first hole body 1132 , that is, the first guide hole 1131 may be in an inverted figure eight shape to facilitate support for the vibration damping wheel shaft 801 .

[0133] As for the thickness of the first guide hole 1131, the first hole body 1132 and the second hole body 1133, they can be set accordingly according to the diameter of the shock-absorbing wheel 800, but it is necessary to ensure that at least part of the shock-absorbing wheel 800 has a plane where the opening of the protruding mounting cavity 112 is located, so that the circumferential surface of the shock-absorbing wheel 800 can be in rolling contact with the wheel disc 200 to achieve shock absorption of the wheel disc 200.

[0134] In some embodiments, the first mounting holes 113 are provided on opposite sides of the mounting cavity 113 , and both ends of the vibration-damping wheel shaft 801 are disposed in the corresponding first mounting holes 113 .

[0135] 16 and 17 , the diameter of the shock-absorbing wheel 800 is larger than the hole pitch of the second hole body 1133 of the first mounting hole 113. When the shock-absorbing wheel 800 rotates along with the wheel disc 200, the shock-absorbing wheel 800 may move along the axial direction of the shock-absorbing wheel shaft 801. Since the diameter of the shock-absorbing wheel 800 is larger than the hole pitch of the second hole body 1133 of the first mounting hole 113, the axial movement of the shock-absorbing wheel 800 can be limited so that the shock-absorbing wheel 800 can only rotate within the mounting cavity 112. In this case, the shock-absorbing wheel 800 may contact the side wall of the installation cavity 112. Therefore, a baffle can be provided on the outer wall of the first installation hole 113, and the baffle at least covers the outer side of the second hole body 1133. The baffle limits the movement of the shock-absorbing wheel shaft 801 of the shock-absorbing wheel 800, so that the shock-absorbing wheel 800 will not contact the side wall of the installation cavity 112, thereby improving the smoothness of the rotation of the shock-absorbing wheel 800 and further improving the smoothness of the rotation of the wheel disc 200.

[0136] 15 to 17 , in some embodiments, a first mounting groove 1121 may be provided on the side of the first housing 101 facing the wheel disc 200, and a mounting frame 114 may be provided at the opening of the first mounting groove 1121. The mounting frame 114 is in communication with the opening of the first mounting groove 1121 to form the aforementioned mounting cavity 112. The mounting frame 114 may be integrally formed on the end face of the housing 100, and the size of its through hole may be consistent with the size of the opening of the first mounting groove 1121. Of course, in other embodiments, the mounting frame 114 may be detachably connected to the end face of the housing 100 by means of bolts or the like, and the size of the through hole of the mounting frame 114 may be larger or smaller than the size of the opening of the first mounting groove 1121. Corresponding designs may be made without hindering the assembly of the shock-absorbing wheel 800, which will not be elaborated herein.

[0137] To improve the smoothness of the rotation of the shock-absorbing wheel 800, a lubricating layer can be provided on the inner wall of the second hole body 1133 of the first mounting hole 113. In a specific implementation, the lubricating layer can be provided only on the inner wall of the second hole body 1133 by attaching or applying it. The lubricating layer can be made of a soft metal material. Alternatively, the first shell 101 can be made entirely of a self-lubricating material, such as a mixture of nylon and glass fiber, or a polymer-based, ceramic-based material. Accordingly, the inner wall of the second hole body 1133 also has a self-lubricating function, thereby allowing the support wheel shaft 901 to rotate smoothly within the second hole body 1133.

[0138] It should be noted that the above-mentioned shock-absorbing wheel 800 can also be connected to the shock-absorbing wheel shaft 801 in a rotating manner, and the two ends of the shock-absorbing wheel shaft 801 are fixedly connected to the opposite sides of the installation cavity 112, that is, the wheel disc 200 drives the shock-absorbing wheel 800 to rotate on the shock-absorbing wheel shaft 801, which can also achieve the purpose of rolling friction between the wheel disc 200 and the shock-absorbing wheel 800, and no limitation is made here.

[0139] 15-17 , a first support portion 111 is disposed within the first accommodating cavity 104 of the first housing 101 for limiting the movement of the wheel disc 200. The configuration of the first support portion 111 can be referred to in Example 1 and will not be further described here. The aforementioned damping wheel 800 can be disposed on the first support portion 111. The damping wheel 800 not only creates a gap between the wheel disc 200 and the first support portion 111 but also ensures rolling contact between the wheel disc 200 and the first support portion 111, ensuring smooth rotation of the wheel disc 200.

[0140] In addition, the shock-absorbing member 600 shown in the second embodiment can also be provided on the first support portion 111, that is, the shock-absorbing wheel 800 and the shock-absorbing member 600 can both be provided on the first support portion 111. In this case, since the shock-absorbing wheel 800 and the shock-absorbing member 600 can be provided at intervals, on the one hand, the number of shock-absorbing members 600 is reduced to make the wheel 200 rotate smoothly. On the other hand, it can also avoid the vibration and noise caused by the direct contact between the wheel 200 and the first support portion 111 when the shock-absorbing wheel 800 or the shock-absorbing member 600 fails.

[0141] Based on the above-mentioned drying module, the present disclosure also provides a clothing processing device, which includes the above-mentioned drying module.

[0142] The clothing processing device having the above-mentioned drying module has multiple shock-absorbing wheels 800 arranged on the end face of the shell 100 of the drying module. The shock-absorbing wheels 800 are rotatably connected in the shell 100, and the circumferential surface of the shock-absorbing wheels 800 is in rolling contact with the end face of the wheel disc 200. In this way, the sliding friction in the related art can be changed to rolling friction, so as to reduce and improve the friction force when the wheel disc 200 rotates, so that the wheel disc 200 rotates smoothly.

[0143] The clothing processing device may be a clothes dryer or a washer-dryer. Of course, the drying module therein may also be applied to various devices requiring dehumidification, such as dehumidifiers and dishwashers.

[0144] Example 4:

[0145] In related art, a drying module is equipped with support wheels within the housing to provide rolling support for the rotating disc and to act as a limiter, preventing the disc from deflecting and / or colliding with the housing. However, the support wheels are rotatably connected to corresponding support axles, making assembly relatively complex and leaving room for improvement.

[0146] Based on the above technical problems, the present disclosure provides a drying module and a clothes processing device to improve the assembly efficiency of the supporting wheel group to a certain extent.

[0147] FIG18 is a top view of the second shell in FIG9 , FIG19 is a structural schematic diagram of the support wheel group in FIG18 , FIG20 is an assembly schematic diagram of the support wheel group in FIG18 , and FIG21 is a front view schematic diagram of FIG20 . In conjunction with FIG18 to FIG21 , the drying module includes a shell 100, a wheel disc 200 and a plurality of support wheel groups F. The wheel disc 200 is rotatably disposed in the shell 100. The inner side of the shell 100 is provided with a plurality of second mounting grooves 115 , and at least one side of the second mounting groove 115 is provided with a second mounting hole 116 , The second mounting hole 116 extends from the opening of the second mounting groove 115 in a direction away from the wheel disc 200 , and the second mounting hole 116 includes a third hole body 1162 and a second hole body 1163 that are sequentially connected to the opening of the second mounting groove 115 The fourth hole body 1163; the support wheel group F and the second mounting groove 115 are arranged correspondingly, the support wheel group F includes a support wheel 900 and a support wheel shaft 901, the support wheel 900 is fixedly connected to the support wheel shaft 901, the support wheel shaft 901 and the third hole body 1162 are at least partially interference fit, the support wheel shaft 901 is arranged in the fourth hole body 1163 with a clearance fit, the support wheel 900 at least partially protrudes from the plane where the opening of the second mounting groove 115 is located, the support wheel 900 and the wheel disc 200 are in rolling contact to support the wheel disc 200.

[0148] In the drying module provided by the present disclosure, since the support wheel 900 of the support wheel assembly F is fixedly connected to the support wheel 900, in a specific implementation, the support wheel shaft 901 having the support wheel 900 can be placed at the opening of the second mounting groove 115, and then the support wheel shaft 901 is pressed downward so that the end of the support wheel shaft 901 passes through the third hole 1162 and enters the fourth hole 1163. Since the support wheel shaft 901 is arranged in the fourth hole 1163 with a clearance fit, the support wheel 900, under the drive of the wheel disc 200, will drive the support wheel shaft 901 to rotate in the fourth hole 1163. Due to the at least partial interference fit between the support wheel shaft 901 and the third hole 1162, the support wheel shaft 901 can be restricted from entering the third hole 1162 from the fourth hole 1163, thereby preventing the support wheel shaft 901 from escaping from the corresponding second mounting groove 115, and allowing the support wheel shaft 901 to rotate normally.

[0149] Since the supporting wheel set F can be assembled into place only by pressing downward, the assembly efficiency of the supporting wheel set F can be improved, and the device has good practicality.

[0150] In combination with Figures 20 and 21, in some embodiments, the fourth hole body 1163 can be arc-shaped so that the support wheel shaft 901 can rotate in the fourth hole body 1163, and the third hole body 1162 has at least a hole diameter that is smaller than the diameter of the fourth hole body 1163, so that the support wheel shaft 901 can rotate in the fourth hole body 1163 but cannot escape through the third hole body 1162.

[0151] 19 and 20 , the third hole body 1162 may be rectangular, the aperture of the third hole body 1162 needs to be smaller than the diameter of the fourth hole body 1163, and the central angle of the fourth hole body 1163 needs to be greater than 180°, so that the end of the support axle 901 can be passed through the third hole body 1162 by pressing down, and the support axle 901 can be rotated in the fourth hole body 1163, but cannot escape from the third hole body 1163, so as to limit the support axle 901 in a direction parallel to the central axis of the wheel disc 200.

[0152] In other embodiments, the third hole body 1162 may be partially rectangular, and the aperture of this part may be smaller than the diameter of the fourth hole body 1163 to prevent the support wheel shaft 901 from escaping from the third hole body 1162, and the remaining part of the third hole body 1162 may be arc-shaped or trapezoidal, etc., which is not limited here.

[0153] In addition, in combination with Figures 20 and 21, the second mounting hole 116 can also include a second guide hole 1161, and the second guide hole 1161 is arranged between the third hole body 1162 and the opening of the second mounting groove 115, that is, the two are transitioned through the second guide hole 1161, and the hole spacing of the second guide hole 1161 close to the opening of the second mounting groove 115 is greater than the hole spacing close to the third hole body 1162. When the support wheel shaft 901 needs to be assembled, the support wheel shaft 901 with the support wheel 900 can be placed in the second guide hole 1161. Since the support wheel shaft 901 and the third hole body 1162 have an interference fit, the support wheel shaft 901 is supported in the second guide hole 1161 of the second mounting hole 116, and the initial positioning of the support wheel shaft 901 can be achieved. The support wheel shaft 901 is then pressed down by external force so that the support wheel shaft 901 passes through the third hole body 1162 and is assembled in the fourth hole body 1163.

[0154] 20 and 21 , in some embodiments, the hole pitch of the second guide hole 1161 gradually decreases from the opening of the second mounting groove 115 toward the third hole body 1162 , that is, the second guide hole 1161 can be in an inverted figure eight shape to facilitate support for the support wheel shaft 901 .

[0155] As for the thickness of the second guide hole 1161, the third hole body 1162 and the fourth hole body 1163, they can be set accordingly according to the diameter of the support wheel 900, but it is necessary to ensure that at least part of the support wheel 900 protrudes from the plane where the opening of the second mounting groove 115 is located, so that the circumference of the support wheel 900 can be in rolling contact with the wheel disc 200, thereby providing effective rolling support for the wheel disc 200.

[0156] In some embodiments, the second mounting holes 116 are disposed on opposite sides of the second mounting slot 115 , and both ends of the support axle 901 are disposed in the corresponding second mounting holes 116 .

[0157] 20 and 21 , the diameter of the support wheel 900 can be larger than the hole pitch of the second mounting holes 116. When the support wheel 900 rotates with the wheel disc 200, the support wheel 900 may move axially along the support wheel shaft 901. Since the diameter of the support wheel 900 is larger than the hole pitch of the second mounting holes 116, this can restrict the axial movement of the support wheel 900, forcing the support wheel 900 to rotate only within the second mounting slot 115. In this case, the support wheel 900 may contact the sidewalls of the mounting slot. Therefore, in some embodiments, a baffle is further provided on the second mounting slot 115, covering at least the outer side of the fourth hole 1163 of the second mounting hole 116. The baffle restricts the movement of the support wheel shaft 901, preventing the support wheel 900 from contacting the sidewalls of the mounting slot, thereby improving the smoothness of the rotation of the support wheel 900 and further improving the smoothness of the rotation of the wheel disc 200.

[0158] In some embodiments, the baffle may cover the outer side of the second mounting hole 116 , or may only cover the outer side of the fourth hole body 1163 of the second mounting hole 116 .

[0159] 19 , the support wheel 900 and the support wheel shaft 901 may be integrally formed, so that the formed support wheel assembly F can be directly assembled to improve the assembly efficiency of the support wheel assembly F.

[0160] To improve the smoothness of rotation of the support wheel 900, a lubricating layer may be provided on the inner wall of the fourth hole 1163 of the second mounting hole 116. In a specific implementation, the lubricating layer may be provided only on the inner wall of the fourth hole 1163 by attaching or applying the lubricating layer. The lubricating layer may be made of a soft metal material. Alternatively, the second housing 102 may be entirely made of a self-lubricating material, such as a mixture of nylon and glass fiber, or a polymer-based, ceramic-based, or other material. Accordingly, the inner wall of the fourth hole 1163 also has a self-lubricating function, thereby allowing the support wheel shaft 901 to rotate smoothly within the second hole 1133.

[0161] In some embodiments, the support wheel 900 of the support wheel shaft 901 is made of a hard material to effectively support the wheel disc 200 and prevent the wheel disc 200 from deflecting or / and colliding with the housing 100 due to deformation of the support wheel 900.

[0162] 18 and 20 , a first support portion 111 for limiting the movement of the wheel 200 is provided in the first accommodating cavity 104 of the first shell 101, and a second support portion 117 for limiting the movement of the wheel 200 is provided in the second accommodating cavity 105 of the second shell 102. The arrangement of the first support portion 111 and the second support portion 117 is similar to that of the first support portion 111 in Example 1 and will not be elaborated here.

[0163] 18 , a plurality of support wheel groups F may be provided on the second support portion 117. By providing the support wheel shaft 901, a gap may be created between the wheel disc 200 and the second support portion 117 to support and limit the wheel disc 200, thereby preventing the wheel disc 200 from deflecting or / and colliding with the housing 100. In addition, the wheel disc 200 is in rolling contact with the support wheel shaft 901 on the second support portion 117, thereby enabling the wheel disc 200 to rotate smoothly.

[0164] In combination with Figures 18, 20 and 21, in some embodiments, a plurality of grooves are arranged at intervals on the second support portion 117, and a support plate 118 is provided on the side of the groove facing the inside of the second support portion 117 (i.e., the inner side of the groove), and the support plate 118 and the groove are configured to form the above-mentioned second mounting groove 115. A second mounting hole 116 is provided on the side of the groove facing the outside of the second support portion 117 and on the support plate 118, and the two ends of the support wheel axle 901 of the support wheel group F are respectively connected to the side of the groove facing the outside of the second support portion 117 and the second mounting hole 116 on the support plate 118.

[0165] In other embodiments, the above-mentioned support plate 118 can be provided on the side of the trough body facing away from the interior of the second support portion 117, or the support plate 118 can be provided on both sides of the trough body facing and / or facing away from the interior of the second support portion 117, that is, the support plates 118 are provided on both sides or one side of the trough body along the radial direction of the wheel disc, the support plates 118 and the trough body are configured to form a second mounting groove 115, and the second mounting hole 116 is provided on the support plate 118.

[0166] In some embodiments, the support plate 118 can be integrally formed on the trough body to facilitate production and processing. The support plate 118 can have a gap between the trough body and both sides along the circumference of the second support portion 117. The gap can be defined as a weight-reducing hole to save production costs to a certain extent.

[0167] Based on the above-mentioned drying module, the present disclosure also provides a clothing processing device, which includes the above-mentioned drying module.

[0168] The clothes processing device with the drying module can improve the assembly efficiency of the supporting wheel set F and has good practicality because the supporting wheel set F can be assembled into place only by pressing downward.

[0169] The clothing processing device may be a clothes dryer or a washer-dryer. Of course, the drying module therein may also be applied to various devices requiring dehumidification, such as dehumidifiers and dishwashers.

[0170] Embodiment 5:

[0171] A limiting wheel is installed within the drying module's housing. It's located outside the periphery of the wheel disc. The periphery of the limiting wheel rolls against the periphery of the wheel disc, driving the limiting wheel's rotation as the wheel disc rotates within the housing. If the wheel disc deviates radially, the limiting wheel acts as a limiting force through rolling contact, helping the disc to follow its designated rotational trajectory without causing significant rotational resistance. This prevents the disc from directly contacting the housing itself, reducing the risk of damage.

[0172] In the related art, the limiting wheel is rotatably connected to the limiting wheel axle. During assembly, the limiting wheel must first be assembled to the limiting wheel axle, and then the limiting wheel axle equipped with the limiting wheel must be assembled into the housing. The assembly method is relatively complicated and has room for improvement.

[0173] Based on this, the present disclosure provides a drying module and a clothes processing device to improve the assembly efficiency of the limiting wheel group G to a certain extent.

[0174] Figure 22 shows a schematic diagram of the arrangement of the limiting wheel group within the second housing, Figure 23 shows a schematic diagram of the structure of the limiting wheel group in Figure 22, and Figure 24 shows a bottom view of Figure 23. In conjunction with Figures 22-24, the drying module includes a housing 100, a wheel disc 200, and a plurality of limiting wheel groups G. The wheel disc 200 is rotatably disposed within the housing 100, and the plurality of limiting wheel groups G are spaced apart within the housing 100. The limiting wheel groups G include a limiting wheel 1000 and a limiting wheel shaft 1005. The limiting wheel 1000 is fixedly disposed on the limiting wheel shaft 1005, and the circumference of the limiting wheel 1000 can contact the circumference of the wheel disc 200.

[0175] The drying module provided by the present disclosure has a limiting wheel 1000 of the limiting wheel group G that is fixedly arranged on the limiting wheel shaft 1005. During assembly, the limiting wheel group G can be directly assembled to the corresponding position of the shell 100, without having to first install the limiting wheel 1000 on the limiting wheel shaft 1005 and then install the limiting wheel shaft 1005 into the shell 100. This can improve assembly efficiency and has good practicality.

[0176] Figure 25 shows a schematic diagram of the assembly of the limiting wheel assembly in Figure 22 on the second housing, Figure 26 shows a schematic diagram of the structure of the second housing where the limiting wheel assembly is assembled, and Figure 27 shows a schematic cross-sectional diagram of the assembly of the limiting wheel assembly in Figure 26 on the second housing. In conjunction with Figures 25-27, in a specific implementation, a third mounting hole 120 is provided on the side of the second housing 102 of the housing 100 facing the wheel disc 200, and the end of the limiting wheel assembly G1001 is rotatably disposed in this third mounting hole 120.

[0177] 25-27 , a second protrusion 119 is provided on the side of the second shell 102 of the shell 100 facing the wheel disc 200 , and the third mounting hole 120 is formed in the second protrusion 119 , and one end of the limiting wheel shaft 1005 is rotatably provided in the third mounting hole 120 .

[0178] 25-27 , a third mounting groove 121 is provided on the side of the second shell 102 of the housing 100 facing the wheel disc 200, and the second protrusion 119 is disposed within the third mounting groove 121. This arrangement can reduce the thickness of the second shell 102 of the housing 100 where the second protrusion 119 is disposed, facilitating the integral injection molding of the second shell 102.

[0179] 25-27 , a first bevel 122 is provided at the opening of the third mounting groove 121. The height of the inner side of the first bevel 122 relative to the side of the second shell 102 facing the wheel disc 200 is smaller than the height of the outer side of the first bevel 122 relative to the side of the second shell 102 facing the wheel disc 200. The outer peripheral surface of the limiting wheel 1000 falls on the first bevel 122 to limit the axial movement of the limiting wheel 1000.

[0180] Since the third mounting groove 121 is provided on the shell 100, the outer peripheral surface of the limiting wheel 1000 falls on the first groove 122 on the third mounting groove 121, so that the contact between the limiting wheel 1000 and the shell 100 is annular, so as to reduce the contact area between the limiting wheel 1000 and the shell 100. When the wheel disc 200 rotates in the shell 100 to drive the limiting wheel 1000 to rotate, the friction between the limiting wheel 1000 and the shell 100 is reduced due to the reduction in contact area, so that the limiting wheel 1000 rotates smoothly, thereby further reducing the rotational resistance to the wheel disc 200 and allowing the wheel disc 200 to operate normally.

[0181] In a specific implementation, the third mounting groove 121 has a columnar structure or a substantially columnar structure, and the inner diameter of the first groove 122 gradually decreases from the opening of the third mounting groove 121 toward the interior of the third mounting groove 121. The second protrusion 119 may also have a columnar structure and be coaxially disposed within the second mounting groove 121. Of course, the second protrusion 119 may also have other structures such as a square or a frustum, and this is not limited here.

[0182] As described above, the shell 100 includes a first shell 101 and a second shell 102 connected to each other. The first shell 101 is provided with a first accommodating cavity 104, and the second shell 102 is provided with a second accommodating cavity 105. When the first shell 101 and the second shell 102 are assembled, the first accommodating cavity 104 and the second accommodating cavity 105 are configured as accommodating cavities for loading the wheel disc 200. The wheel disc 200 is rotatably arranged in the accommodating cavity, and the first shell 101 can be located above the second shell 102. Combined with Figure 27, the axial direction of the limiting wheel 1000 is parallel or nearly parallel to the axial direction of the wheel disc 200. Under the action of gravity, the limiting wheel 1000 will fall on the second shell 102. Therefore, the third mounting groove 121 is set on the side of the second shell 102 facing the wheel disc 200, and the first shell 101 can only be provided with a fourth mounting hole 123 corresponding to the limiting wheel shaft 1005. The fourth mounting hole 123 can be a blind hole. The fourth mounting hole 123 and the third mounting hole 120 on the second protrusion 119 are coaxially arranged. The upper end of the limiting wheel shaft 1005 is rotatably set in the fourth mounting hole 123, and the lower end of the limiting wheel shaft 1005 is rotatably set in the third mounting hole 120 on the second protrusion.

[0183] Figure 28 is a schematic diagram of the assembly of the limiting wheel group in the shell when the third mounting hole is a blind hole. In combination with Figure 28, in other embodiments, only the third mounting hole 120 can be set on the side of the second shell 102 facing the wheel disc 200, without setting the third mounting groove 120 and the second protrusion 119. The third mounting hole 120 is also a blind hole, and the upper end of the limiting wheel shaft 1005 is rotatably set in the fourth mounting hole 123, and the lower end of the limiting wheel shaft 1005 is rotatably set in the third mounting hole 120 on the second shell 102.

[0184] 22 , a second supporting ring 112 is provided in the second accommodating cavity 105 of the second shell 102 , and a plurality of limiting wheel groups G are assembled at intervals in the second accommodating cavity 105 outside the second supporting ring 112 .

[0185] 23 and 24 , the limiting wheel 1000 includes an outer wheel body 10001, an inner wheel body 10002, and support ribs 10003. The inner wheel body 10002 can be fixed on the limiting wheel shaft 1005 in an integrated manner. The outer wheel body 10001 is arranged on the side of the limiting wheel shaft 1005 away from the inner wheel body 10002, that is, the outer wheel body 10001 is arranged on the outside of the inner wheel body 1002. The outer wheel body 10001 and the inner wheel body 10002 are connected by multiple support ribs 10003. The outer wheel body 10001 of the limiting wheel 1000 falls on the first groove 122, that is, the first groove 122 can limit the outer wheel body 10001 from moving to the outside of the third mounting groove 121.

[0186] 25-27 , a second groove 124 is further provided at the opening of the third mounting hole 120 of the second protrusion 119. The height of the inner side of the second groove 124 relative to the side of the second housing 102 facing the wheel disc 200 is less than the height of the outer side of the second groove 124 relative to the side of the second housing 102 facing the wheel disc 200. The inner diameter of the second groove 124 can gradually decrease along the opening of the third mounting hole 120 toward the interior of the third mounting hole 120. The inner wheel body 10002 of the limiting wheel 1000 rests on the second protrusion 119. A support ring 10004 is provided at the end of the inner wheel body 10002 facing the second protrusion 119. The projection of the support ring 10004 on the second protrusion 119 is located outside the second groove 124.

[0187] 25-27 , the support ring 10004 on the inner wheel body 10002 can reduce the contact area between the inner wheel body 10002 and the second protrusion 119, and accordingly reduce the contact between the limiting wheel 1000 and the housing 100. When the wheel disc 200 rotates within the housing 100 to drive the limiting wheel 1000 to rotate, the friction between the limiting wheel 1000 and the housing 100 is reduced, thereby ensuring smooth rotation of the limiting wheel 1000, further reducing the rotational resistance to the wheel disc 200 and enabling normal operation of the wheel disc 200. The second groove 124 provides space for the floating generated by the rotation of the limiting wheel shaft 1005, thereby ensuring smooth rotation of the limiting wheel shaft 1005.

[0188] In conjunction with Figure 26, one or more second reinforcing ribs 125 may be provided between the circumferential surface of the second protrusion 119 and the side wall of the third mounting groove 121. The second reinforcing ribs 125 are also connected to the bottom of the third mounting groove 121 to increase the connection strength of the second protrusion 119 in the third mounting groove 121, thereby improving the reliability of assembly.

[0189] Since there is a hole distance between the circumference of the second protrusion 119 and the side wall of the third mounting groove 121, the thickness of the second shell 102 at the location where the second protrusion 119 is set will be relatively thin, so that the wall thickness of the second shell 102 at the location where the third mounting groove 121 is set can be uniform, thereby avoiding the phenomenon of local poor injection molding due to excessive thickness in the production process and improving the flatness of the end face of the shell 100.

[0190] 26 , the bottom and sidewalls of the third mounting groove 121 may be transitioned through a curved connecting portion 126 . The connecting portion 126 may be a curved surface to facilitate the processing and manufacturing of the third mounting groove 121 .

[0191] In addition, the circumference of the limiting wheel 1000 is made of an elastic material. When the wheel disc 200 deflects slightly, the limiting wheel 1000 can deform to accommodate the small deviation of the wheel disc 200. The support ribs 10003 have at least one curved structure. When the limiting wheel 1000 deforms, the support ribs 10003 are forced to deform accordingly. If the support ribs 10003 were linear, they would likely break. Therefore, the support ribs 10003 should have at least one curved structure to accommodate the deformation of the limiting wheel 1000. The curved structure can be arc-shaped, wavy, or a combination of these, without limitation.

[0192] In order to improve the smoothness of the rotation of the limiting wheel 1000, a lubricating layer can be provided on the inner walls of the third mounting hole 120 of the second protrusion 119 and the fourth mounting hole 123 of the first shell 101. In a specific implementation, the lubricating layer can be provided only on the inner walls of the corresponding hole bodies by attaching or applying. The lubricating layer can be made of a soft metal material. Alternatively, the first shell 101 and the second shell 102 can be made of a self-lubricating material as a whole. The self-lubricating material can be a mixture of nylon and glass fiber or a polymer-based, ceramic-based material, etc., which also makes the inner walls of the hole bodies have a self-lubricating function, thereby ensuring smooth rotation of the limiting wheel shaft 1005.

[0193] For clarity, Figure 8 omits part of the outer shell of the washer-dryer. Referring to Figure 8 , the washer-dryer W includes a clothing container R and a drying module D. The clothing container R can be a drum, comprising an inner drum and an outer drum. The inner drum of the clothing container R can be driven to rotate by an external force, while the outer drum is configured to be suspended or hoisted on the washer-dryer frame. The water inlet and outlet are respectively connected to the clothing container R. The drying module D includes a moisture-dissipating component D1, a moisture absorption channel D2, and a moisture-dissipating channel D3. The moisture absorption channel D2 includes a moisture absorption channel air inlet and a moisture absorption channel air outlet, with the clothing container R being connected to the moisture absorption channel air inlet and the moisture absorption channel air outlet, respectively. A moisture absorption channel fan D21 is also provided in the moisture absorption channel D2 to form a circulating moisture absorption airflow within the clothing container R and the moisture absorption channel D2. A moisture-dissipating channel fan D31 is provided in the moisture-dissipating channel D3 to form a moisture-dissipating airflow within the moisture-dissipating channel D3. The moisture absorption and dehumidification component D1 is the aforementioned wheel 200. The moisture absorption and dehumidification component D1 is disposed in the path of the moisture absorption channel D2 and the moisture dehumidification channel D3, so that both the moisture absorption airflow and the moisture dehumidification airflow flow through the moisture absorption and dehumidification component D1. As a result, the moisture absorption and dehumidification component D1 absorbs moisture from the moisture absorption airflow during rotation and discharges the absorbed moisture through the moisture dehumidification airflow. Of course, the washer-dryer W may also include, but is not limited to, an outer shell having at least a clothing access opening and a detergent inlet, a door for closing the clothing access opening, a display and operating device arranged on the outer shell, a frame, a controller, a drain pipe, and other components to achieve the clothing washing and drying functions and control the washer-dryer.

[0194] In conjunction with Figures 8 and 26 , since the air inlet of moisture absorption channel D2 and the air outlet of moisture discharge channel D3 are moisture-rich areas of the housing, some third mounting slots 121 can be positioned in moisture-rich areas of the housing 100. Drain holes 128 can be provided at the bottom of the third mounting slots 121 located in moisture-rich areas of the housing 100. These drain holes communicate with the exterior of the housing 100 to drain water droplets formed by condensation, thereby improving moisture absorption efficiency. Drain holes 128 can be omitted from the bottom of the third mounting slots 121 located in moisture-sparse areas of the housing 100. These moisture-sparse areas can serve as the air outlet of moisture absorption channel D2 and the air inlet of moisture discharge channel D3.

[0195] Based on the above-mentioned drying module, the present disclosure also provides a clothing processing device, which includes the above-mentioned drying module.

[0196] The clothing processing device having the above-mentioned drying module, since the limiting wheel 1000 of the drying module is fixedly set on the limiting wheel shaft 1005, during assembly, the limiting wheel group G can be directly assembled to the corresponding position of the shell 100, without having to first install the limiting wheel 1000 on the limiting wheel shaft 1005 and then install the limiting wheel shaft 1005 into the shell 100 for assembly, which can improve the assembly efficiency and has good practicality.

[0197] The clothing processing device may be a clothes dryer or a washer-dryer. Of course, the drying module therein may also be applied to various devices requiring dehumidification, such as dehumidifiers and dishwashers.

[0198] Example 6:
