[0041] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] The knob is a module electrically connected to the clothes processing device, and the user can adjust and control a certain function of the clothes processing device by turning the knob. For example, it is used to adjust the working module, drying temperature, drying time, soaking time, speed, etc. of the clothes processing device.

[0043] However, in the related art, a knob is usually injection molded on a metal driving member to form a non-metallic connecting member, and the driving member is connected to the transmission assembly through the connecting member. This results in a complex structure of the knob, cumbersome processing, and high injection molding cost. In addition, since the connecting member needs to be used as an intermediate adapter to achieve the connection between the connecting structure and the driving member, the connection reliability between the transmission assembly and the driving member is reduced.

[0044] Based on this, the embodiments of the present application provide a knob and a clothing processing device, aiming to improve the problems of complex knob structure, cumbersome processing and high injection molding cost.

[0045] See also Figure 1 An embodiment of the present application provides a knob 1 and a clothing processing device. The clothing processing device can be a dryer, a washing machine, a dryer-washer, etc. The clothing processing device includes a shell, a controller and a knob 1. The controller is installed in the shell. The controller can be used to select a washing program or a drying program, or adjust the drying temperature, drying time, soaking time, etc. of the clothing processing device.

[0046] The knob 1 includes a driving member 11 and a transmission assembly 12. The driving member 11 is a metal member, so that the driving member 11 has a high hardness and strong corrosion resistance, thereby strengthening the driving member 11 to protect the transmission assembly 12 and the components in the knob 1. The driving member 11 can be made of an aluminum alloy material, a zinc alloy material, or an alloy of other materials, which is not specifically limited here.

[0047] In some embodiments, the driving member 11 can at least partially extend out of the housing, so that the user can drive the driving member 11 to rotate by holding the portion of the driving member 11 extending out of the housing. The driving member 11 can be cylindrical, the driving member 11 can be cap-shaped, the driving member 11 can be ring-shaped, and the driving member 11 can be other irregular shapes, which are not specifically limited here. In some embodiments, the driving member 11 can partially extend out of the housing when needed, and retract into the box when not needed, so as to improve the neatness and aesthetics of the appearance of the box.

[0048] The transmission assembly 12 is at least partially mounted on the housing and is provided with a first connection portion 124. The driving member 11 is provided with a second connection portion 111. The second connection portion 111 is suitable for connecting with the first connection portion 124. It can be understood that the driving member 11 is connected to the transmission assembly 12 through the first connection portion 124 and the second connection portion 111. When the second connection portion 111 is connected to the first connection portion 124, the user drives the driving member 11 to rotate, and the driving member 11 drives the transmission assembly 12 to rotate relative to the housing. There are many ways to connect the first connection portion 124 and the second connection portion 111. The first connection portion 124 and the second connection portion 111 can be snap-fit, rotationally fit, or screw-fitted, which is not specifically limited here.

[0049] The transmission assembly 12 is at least partially connected to the controller. When the second connection portion 111 is connected to the first connection portion 124, the driving member 11 drives the transmission assembly 12 to rotate around the rotation axis to trigger the transmission assembly 12 to transmit a control signal to the controller. There are many ways to connect the transmission assembly 12 to the controller. The transmission assembly 12 can be electrically connected to the controller by wire connection, or by wireless means such as Bluetooth, WIFI, etc., or by optical signal connection, or by converting optical signals into electrical signals. No specific limitation is made here.

[0050] It should be noted that the first connection portion 124 and the second connection portion 111 are arranged on the two wall surfaces opposite to the driving member 11 and the transmission assembly 12. In some embodiments, the driving member 11 is in a cap-like or ring-like shape. Of course, the driving member 11 can also be in other shapes, which are not specifically limited here. The driving member 11 is sleeved on the outer peripheral side of the transmission assembly 12, the first connection portion 124 is arranged on the inner surface of the driving member 11, and the second connection portion 111 is arranged on the outer wall of the transmission assembly 12. For another example, the driving member 11 is located at one end of the transmission assembly 12 on the rotation axis, the first connection portion 124 is arranged on the surface of the driving member 11 facing the transmission assembly 12 on the rotation axis, and the second connection portion 111 is arranged on the surface of the transmission assembly 12 on the rotation axis facing the driving member 11, which are not listed one by one here.

[0051] The knob 1 in the embodiment of the present application does not need to be provided with a non-metallic connector on the driver 11 to install the driver 11 on the transmission assembly 12, thereby simplifying the structure of the knob 1 and reducing the injection molding cost of the knob 1. The driver 11 is directly connected to the transmission assembly 12 through the first connecting portion 124 and the second connecting portion 111, which can improve the connection reliability between the transmission assembly 12 and the driver 11.

[0052] See also Figure 2In some embodiments of the present application, the driving member 11 has an opening 11a on one side in the rotation axis direction, and the transmission assembly 12 is suitable for being assembled to the driving member 11 from the opening 11a. The inner surface of the driving member 11 is provided with a mounting section 112 and a non-mounting section 113 in sequence from the opening 11a along the rotation axis. The wall thickness of the mounting section 112 is less than the wall thickness of the non-mounting section 113, and the second connecting portion 111 is provided at the mounting section 112. In this way, by reducing the wall thickness of the mounting section 112, the contact area between the end of the driving member 11 close to the transmission assembly 12 on the rotation axis and the transmission assembly 12 is reduced, thereby reducing the wear of the driving member 11 and the transmission assembly 12 during the assembly process, and providing an installation space for the connection between the driving member 11 and the transmission assembly 12. Since the driving member 11 is provided with the opening 11a, the driving member 11 can be in a cover shape or a ring shape, which is not specifically limited here. During the assembly process of the driving member 11 and the transmission assembly 12, the transmission assembly 12 will extend into the driving member 11 through the opening 11a. The wall thickness of the mounting section 112 is smaller than that of the non-mounting section 113 . It can be understood that the distance from any point on the inner surface of the mounting section 112 to the rotation axis is greater than the distance from any point on the inner surface of the non-mounting section 113 to the rotation axis.

[0053] For some implementation plans, please also refer to Figures 2 to 3 The inner surface of the installation section 112 is provided with a limiting groove 1122, which extends from the opening 11a side toward the non-installation section 113 and forms a limiting wall 112a on the side away from the opening 11a. The outer wall of the transmission assembly 12 is provided with a limiting portion 125, which is at least partially located in the limiting groove 1122 and abuts against the limiting wall 112a. In this way, during the assembly process of the driving member 11 and the transmission assembly 12, the limiting groove 1122 and the limiting portion 125 can cooperate to limit the driving member 11 and the transmission assembly 12 in the axial direction, so that the driving member 11 can be accurately sleeved on the specified position of the transmission assembly 12 on the rotation axis, thereby facilitating the assembly of the knob 1.

[0054] In some embodiments, the limiting groove 1122 is arranged in a ring shape, so as to ensure that the limiting portion 125 can extend into the limiting groove 1122 when the driving member 11 is sleeved on the transmission assembly 12, thereby reducing the steps of aligning the limiting groove 1122 and the limiting portion 125 during the assembly process of the driving member 11 and the transmission assembly 12, thereby improving the assembly efficiency of the knob 1.

[0055] Please also read Figures 2 to 3In some embodiments, the inner surface of the mounting section 112 is provided with a limiting protrusion 1121, and the limiting protrusion 1121 can cooperate with at least part of the outer wall of the transmission assembly 12 to limit the radial position of the transmission assembly 12. In the case where the driving member 11 is at least partially annular, since the entire ring of the driving member 11 may not be of equal diameter during the manufacturing process, such a setting can reduce the gap between the mounting section 112 and the transmission assembly 12 through the limiting protrusion 1121, thereby reducing the radial error between the annular driving member 11 and the transmission assembly 12, and can limit the radial position of the transmission assembly 12, thereby avoiding the relative movement of the annular driving member 11 and the transmission assembly 12 in the radial direction during the rotation of the annular driving member 11 and the transmission assembly 12, and further improve the transmission stability between the transmission assembly 12 and the annular driving member 11.

[0056] In some embodiments, the distance between the end of the limiting protrusion 1121 close to the opening 11a and the opening 11a is smaller than the distance between the end of the transmission assembly 12 extending into the driving member 11 and the opening 11a.

[0057] The limiting protrusion 1121 may be arranged in a ring shape, or may be composed of a plurality of protrusions arranged at intervals along the circumference of the driving member 11, which is not specifically limited here.

[0058] It should be noted that the driving member 11 is connected to the transmission assembly 12 by connecting the first connecting portion 124 and the second connecting portion 111. The second connecting portion 111 is arranged on the inner surface of the mounting section 112. At this time, there are many types of positional relationships between the limiting protrusion 1121 and the second connecting portion 111.

[0059] For example, see Figure 4 The inner surface of the mounting section 112 is provided with a second connection portion 111, and the second connection portion 111 is located on the side of the limiting protrusion 1121 away from the non-mounting section 113, and the outer wall of the transmission assembly 12 is provided with a first connection portion 124. At this time, the space of the driving member 11 in the rotation axis direction is fully utilized, and at the same time, the first connection portion 124 can be prevented from interfering with the limiting protrusion 1121 during the assembly process of the transmission assembly 12 and the driving member 11.

[0060] For example, see Figure 5, the inner surface of the mounting section 112 is provided with a second connection portion 111, the limiting protrusion 1121 is at least partially located on one side of the second connection portion 111 in the circumferential direction of the driving member 11, and the outer wall of the transmission assembly 12 is provided with a first connection portion 124. At this time, the space of the driving member 11 in the circumferential direction is fully utilized, so that the structure of the knob 1 is more compact, and the axial length of the knob 1 can be reduced. Preferably, the two boundaries of the second connection portion 111 in the axial direction of the knob 1 do not exceed the two boundaries of the limiting protrusion 1121 in the axial direction of the knob 1, which can be understood as follows: the distance between the boundary of the second connection portion 111 close to the opening 11a and the opening 11a is greater than or equal to the distance between the boundary of the limiting protrusion 1121 close to the opening 11a and the opening 11a, and the distance between the boundary of the second connection portion 111 away from the opening 11a and the opening 11a is less than or equal to the distance between the boundary of the limiting protrusion 1121 away from the opening 11a and the opening 11a. This can avoid interference between the first connecting portion 124 and the limiting protrusion 1121 during the assembly process of the transmission assembly 12 and the driving member 11 .

[0061] When the limiting protrusion 1121 is located on the circumferential side of the second connecting portion 111 of the driving member 11, the inner surface of the mounting section 112 is further provided with a tool withdrawal groove 1123, and the second connecting portion 111 is arranged in the tool withdrawal groove 1123. One end of the tool withdrawal groove 1123 in the circumferential direction of the driving member 11 is connected to the limiting protrusion 1121, thereby facilitating the processing of the limiting protrusion 1121.

[0062] For details, please refer to Figure 1 , Figure 4 as well as Figure 6 One of the first connection portion 124 and the second connection portion 111 includes a snap-fitting groove 124a, and the other of the first connection portion 124 and the second connection portion 111 includes a snap-fitting portion 111a, and the snap-fitting portion 111a is suitable for snapping with the snap-fitting groove 124a. In this way, the transmission assembly 12 and the driving member 11 can be connected to each other by snapping the snap-fitting portion 111a with the snap-fitting groove 124a, thereby facilitating the assembly of the knob 1 assembly.

[0063] During the assembly process of the knob 1, the driving member 11 can move along the axial direction relative to the transmission component 12 to snap the snap-fitting portion 111a into the snap-fitting groove 124a, and the driving member 11 can also rotate circumferentially relative to the transmission component 12 to snap-fit ​​the snap-fitting portion 111a into the snap-fitting groove 124a, which is not specifically limited here.

[0064] For further information, see Figure 6, one of the first connection part 124 and the second connection part 111 provided with the snap-fit ​​groove 124a is also provided with a mounting channel 124b, the mounting channel 124b extends along the rotation axis of the knob 1, and the mounting channel 124b is located on one side of the snap-fit ​​groove 124a in the circumferential direction of the transmission assembly 12. It can be understood that when the mounting channel 124b and the snap-fit ​​groove 124a are provided in the transmission assembly 12, the mounting section 112 is provided with the snap-fit ​​portion 111a. When the mounting channel 124b and the snap-fit ​​groove 124a are provided in the mounting section 112, the transmission assembly 12 is provided with the snap-fit ​​portion 111a.

[0065] During the assembly process of the transmission assembly 12 and the driving member 11, the buckling portion 111a can extend into the installation channel 124b along the rotation axis, and the transmission assembly 12 can rotate relative to the driving member 11, so that the buckling portion 111a and the buckling groove 124a are buckled and matched. It should be noted that one end of the installation channel 124b needs to be connected to the opening 11a, so that the buckling portion 111a can extend into the installation channel 124b along the rotation axis.

[0066] In this way, by providing an installation channel 124b extending along the rotation axis, during the assembly process of the transmission component 12 and the driving member 11, the installation channel 124b can guide the snap-fitting portion 111a to move along the rotation axis, so that the driving member 11 can be sleeved on the transmission component 12 along the rotation axis. Subsequently, the driving member 11 and the transmission component 12 only need to be driven to rotate relative to each other to snap the snap-fitting portion 111a into the snap-fitting groove 124a, so that the driving member 11 and the transmission component 12 can be fixedly connected, thereby facilitating the assembly of the knob 1.

[0067] The snap-fitting portion 111a may be formed by a convex portion, which is snap-fitted with the snap-fitting groove 124a. In this case, a surface of the mounting channel 124b close to the mounting section 112 is provided with an avoidance hole for the snap-fitting portion 111a to extend into the mounting channel 124b. The snap-fitting portion 111a may also be provided in a hook shape to have a connecting portion and a convex portion. In this case, an avoidance channel is also provided on the outer wall surface of the transmission component 12. The avoidance channel and the snap-fitting groove 124a are located on the same side of the mounting channel 124b in the circumferential direction of the transmission component 12. The avoidance channel is connected to the mounting channel 124b and the snap-fitting groove 124a. When the transmission component 12 and the driving member 11 rotate relative to each other, the connecting portion rotates in the avoidance channel and the convex portion snaps into the snap-fitting groove 124a. They are not listed one by one here.

[0068] It should be noted that after the knob 1 is assembled, the snap-fitting portion 111a is snap-fitted with the snap-fitting groove 124a, and the driving member 11 drives the transmission assembly 12 to rotate through the snap-fitting portion 111a and the snap-fitting groove 124a. There are many ways to prevent the snap-fitting portion 111a from exiting the snap-fitting groove 124a. For example, when the distance between the wall surface of the snap-fitting groove 124a facing the inner surface of the mounting section 112 and the inner surface of the mounting section 112 is greater than the distance between the wall surface of the mounting channel 124b facing the inner surface of the mounting section 112 and the inner surface of the mounting section 112, the snap-fitting groove 124a is connected to the mounting channel 124b, and the step formed between the wall surface of the mounting channel 124b facing the inner surface of the mounting section 112 and the wall surface of the snap-fitting groove 124a facing the inner surface of the mounting section 112 abuts against the snap-fitting portion 111a. For another example, by providing a limiting protrusion 124d between the locking groove 124a and the installation channel 124b, the locking portion 111a is prevented from retreating by abutting the limiting protrusion 124d against the locking portion 111a, which will not be listed here one by one.

[0069] Considering that the thickness of the driver 11 at the installation section 112 is relatively small, if the inner surface of the installation section 112 is recessed to form the installation channel 124b and the buckling groove 124a, the thickness of the driver 11 at the installation channel 124b and the buckling groove 124a will be even smaller, resulting in insufficient strength of the driver 11 at the installation section 112. In view of this, please refer to Figure 1 , Figure 4 as well as Figure 6 The second connecting portion 111 includes a snap-fitting portion 111a, and the first connecting portion 124 includes an installation channel 124b and a snap-fitting groove 124a. With such an arrangement, the strength of the driving member 11 can be improved by the snap-fitting portion 111a at the inner surface of the installation section 112, and the driving member 11 is a metal part, which facilitates the processing of the snap-fitting portion 111a.

[0070] For further information, see Figure 6 The first connection portion 124 further includes a limiting protrusion 124d, which is located between the buckling groove 124a and the installation channel 124b. The limiting protrusion 124d is suitable for abutting against the buckling portion 111a, and prevents the buckling portion 111a from exiting the buckling groove 124a when the transmission assembly 12 is buckled with the driving member 11. Such a configuration can make the buckling portion 111a more stably buckled with the buckling groove 124a, and the driving member 11 can drive the transmission assembly 12 to rotate through the buckling portion 111a, the buckling groove 124a and the limiting protrusion 124d, so that the driving member 11 can better drive the transmission assembly 12 to rotate.

[0071] Specifically, see Figure 6The installation channel 124b has a first depth in the radial direction, the buckling groove 124a has a second depth in the radial direction, the first depth is greater than the second depth, and the installation channel 124b has an inclined surface 124e extending from the installation channel bottom wall 124c to the buckling groove 124a, and the limiting protrusion 124d is provided with a guide surface 124f on one side close to the installation channel 124b, and at least part of the inclined surface 124e is coplanar with the guide surface 124f. In this way, when the transmission assembly 12 and the driving member 11 rotate relative to each other, the buckling portion 111a abuts against the guide surface 124f to guide the buckling portion 111a to buckle into the buckling groove 124a through the limiting protrusion 124d, thereby facilitating the assembly of the knob 1.

[0072] For further information, see Figure 4 , a guiding bevel 111b is provided at one end of the buckling portion 111a in the circumferential direction of the transmission assembly 12; wherein, during the assembly process of the transmission assembly 12 and the driving member 11, the guiding bevel 111b cooperates with the guiding surface 124f to guide the buckling portion 111a to buckle into the buckling groove 124a. In this way, the guiding bevel 111b cooperates with the guiding surface 124f to guide the buckling portion 111a to buckle into the buckling groove 124a through the limiting protrusion 124d, thereby facilitating the assembly of the knob 1. It can be understood that the guiding bevel 111b and the guiding surface 124f are inclined in the same direction, so that the contact area between the guiding bevel 111b and the guiding surface 124f can be increased during the assembly process of the transmission assembly 12 and the driving member 11, thereby improving the guiding effect of the guiding bevel 111b and the guiding surface 124f.

[0073] See also Figure 6 In some embodiments of the present application, the distance from the convex top of the snap-fitting portion 111a to the inner surface of the mounting section 112 is smaller than the distance from the wall of the inner surface of the mounting channel 124b facing the mounting section 112 to the inner surface of the mounting section 112, that is, the radial height of the snap-fitting portion 111a is smaller than the depth of the mounting channel 124b. With this arrangement, during the assembly process of the transmission assembly 12 and the driving member 11, there will be a gap between the snap-fitting portion 111a and the wall of the inner surface of the mounting channel 124b facing the mounting section 112, thereby reducing the friction between the snap-fitting portion 111a and the mounting channel 124b, thereby facilitating the assembly of the knob 1.

[0074] See also Figure 7In some embodiments of the present application, the knob 1 is provided with multiple groups of mounting channels 124b, buckling grooves 124a and buckling portions 111a, and the multiple groups of mounting channels 124b, buckling grooves 124a and buckling portions 111a are arranged at intervals along the circumference of the transmission assembly 12. In this way, during the assembly of the driving member 11 and the transmission assembly 12, the multiple groups of mounting channels 124b, buckling grooves 124a and buckling portions 111a cooperate so that the driving member 11 can be better sleeved on the transmission assembly 12 along the rotation axis, thereby facilitating the assembly of the knob 1.

[0075] See also Figure 3 In some embodiments of the present application, the outer wall of the driving member 11 is provided with a plurality of anti-skid protrusions 114 arranged at intervals. In this way, the plurality of anti-skid protrusions 114 can increase the friction coefficient of the outer wall of the driving member 11, thereby facilitating the user to rotate the driving member 11, and further facilitating the user to use the knob 1.

[0076] See also Figure 7 In some embodiments of the present application, the transmission assembly 12 includes a connection structure 122 and a main structure 121. The connection structure 122 is suitable for transmission connection with the driving member 11 and rotates with the rotation of the driving member 11. The connection structure 122 is provided with a sensed member 123. The main structure 121 is at least partially installed on the housing of the clothing processing device. The main structure 121 is provided with a sensing member 1211, wherein the sensed member 123 rotates relative to the sensing member 1211 during the rotation of the driving member 11 to trigger the sensing member 1211 to transmit a control signal to the controller. In this way, the sensed member 123 is driven to rotate relative to the sensing member 1211 by the connection structure 122, so that the sensing member 1211 recognizes the rotation of the sensed member 123 to transmit a control signal to the controller, and there is no need to set other components to drive the sensed member 123 to rotate, thereby simplifying the structure of the knob 1.

[0077] The connection structure 122 can be made of metal material or plastic, which is not specifically limited here. Preferably, the connection structure 122 is a plastic part, which can reduce the cost of the knob 1 and avoid the connection structure 122 from affecting the sensing part 1211 and the sensing part 123. The sensing part 1211 and the sensing part 123 can be a magnetic ring and a Hall sensor, and the sensing part 1211 and the sensing part 123 can also be an infrared transmitter and an infrared sensor, which is not specifically limited here.

[0078] There are many ways to install the main structure 121 on the shell. The main structure 121 can be installed on the shell by screw connection, or by snap-fitting. No specific limitation is made here.

[0079] The main structure 2 comprises a connecting part 1212, which is at least partially connected to the housing of the laundry treating apparatus.
