DETAILED DESCRIPTION

[0040] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0041] The rotary knob is a module electrically connected with a clothes treatment apparatus, and a user can adjust and control a certain function of the clothes treatment apparatus by rotating the rotary knob. For example, the rotary knob is used to adjust a working module, a drying temperature, a drying time, an immersion time, a rotating speed, etc. of the clothes treatment apparatus.

[0042] However, in the related art, the knob is usually formed by injection molding a non-metallic connecting piece on a metallic driving piece, and the driving piece is connected with the transmission assembly through the connecting piece, which leads to complex structure, complicated processing, high injection molding cost, and reduced connection reliability between the transmission assembly and the driving piece due to the need of the connecting piece as an intermediate adapter to realize the connection between the connecting structure and the driving piece.

[0043] Based on this, the embodiments of the present application provide a knob and a clothes processing device, aiming to improve the problems of complex structure, complicated processing, and high injection molding cost.

[0044] Please refer to Figure 1 The embodiments of the present application provide a knob 1 and a clothes processing device, which can be a dryer, a washing machine, a drying-washing integrated machine, etc. The clothes processing device comprises a shell, a controller, and the knob 1. The controller is installed in the shell, and can be used to select a washing program or a drying program, or adjust the drying temperature, drying time, soaking time, etc. of the clothes processing device.

[0045] The knob 1 comprises a driving piece 11 and a transmission assembly 12. The driving piece 11 is a metal piece, so that the driving piece 11 has high hardness and strong corrosion resistance, thereby strengthening the protection of the driving piece 11 on the transmission assembly 12 and the components in the knob 1. The material of the driving piece 11 can be an aluminum alloy material, a zinc alloy material, or an alloy of other materials, which is not limited here.

[0046] In some embodiments, the driving piece 11 can at least partially extend out of the shell, so that the user can drive the driving piece 11 to rotate by holding the part of the driving piece 11 extending out of the shell. The driving piece 11 can be columnar, or can be cover-shaped, or can be ring-shaped, or can be other irregular shapes, which is not limited here. In some embodiments, the driving piece 11 can partially extend out of the shell when needed, and can be retracted into the shell when not needed, so as to improve the neatness and aesthetics of the appearance of the shell.

[0047] The transmission assembly 12 is at least partially mounted in the shell, and is provided with a first connecting portion 124. The driving member 11 is provided with a second connecting portion 111, which is adapted to be connected with the first connecting portion 124. It can be understood that the driving member 11 is in transmission connection with the transmission assembly 12 through the first connecting portion 124 and the second connecting portion 111. When the second connecting portion 111 is connected with the first connecting 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 shell. The connection mode of the first connecting portion 124 and the second connecting portion 111 can be various, and the first connecting portion 124 and the second connecting portion 111 can be snap-fitted, rotatably fitted, screw-connected, or plug-fitted, which is not specifically limited here.

[0048] The transmission assembly 12 is at least partially connected with the controller. When the second connecting portion 111 is connected with the first connecting portion 124, the driving member 11 drives the transmission assembly 12 to rotate around the rotation axis, so as to trigger the transmission assembly 12 to transmit a control signal to the controller. The connection mode of the transmission assembly 12 and the controller can be various. The transmission assembly 12 can be electrically connected with the controller through a wire connection mode. The transmission assembly 12 can be electrically connected with the controller through a wireless mode such as Bluetooth or WIFI. The connection mode can also be an optical signal connection or a connection of converting an optical signal into an electrical signal, which is not specifically limited here.

[0049] It should be noted that the first connecting portion 124 and the second connecting portion 111 are arranged on the two opposite walls of the driving member 11 and the transmission assembly 12. In some embodiments, the driving member 11 is in a cover shape or a ring shape, and of course the driving member 11 can also be in other shapes, which is not specifically limited here. The driving member 11 is sleeved on the outer circumferential side of the transmission assembly 12. The first connecting portion 124 is arranged on the inner surface of the driving member 11, and the second connecting portion 111 is arranged on the outer wall of the transmission assembly 12. For example, the driving member 11 is located at one end of the transmission assembly 12 on the rotation axis. The first connecting portion 124 is arranged on the surface of the driving member 11 on the rotation axis and faces the transmission assembly 12. The second connecting portion 111 is arranged on the surface of the transmission assembly 12 on the rotation axis and faces the driving member 11, which is not listed one by one here.

[0050] The knob 1 in the embodiment of the application does not need to be provided with a non-metal connecting member on the driving member 11 to mount the driving member 11 on the transmission assembly 12, so that the structure of the knob 1 is simplified, and the injection molding cost of the knob 1 is reduced. The driving member 11 is directly connected with the transmission assembly 12 through the first connecting portion 124 and the second connecting portion 111, so that the connection reliability between the transmission assembly 12 and the driving member 11 can be improved.

[0051] Please refer to Figure 2In some embodiments of the present application, the driving member 11 has an opening 11a on one side of the rotation axis, the transmission assembly 12 is adapted to be assembled to the driving member 11 from the opening 11a, the inner surface of the driving member 11 is sequentially provided with a mounting section 112 and a non-mounting section 113 along the rotation axis from the opening 11a, the wall thickness of the mounting section 112 is smaller than that of the non-mounting section 113, and the second connecting portion 111 is arranged on 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 along the rotation axis and the transmission assembly 12 is reduced, thereby reducing the wear between the driving member 11 and the transmission assembly 12 during assembly, and providing mounting 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 cover-shaped or ring-shaped, which is not specifically limited here. During the assembly of the driving member 11 and the transmission assembly 12, the transmission assembly 12 extends 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, which can be understood as 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.

[0052] In some embodiments, please refer to Figures 2 to 3 The inner surface of the mounting section 112 is provided with a limiting groove 1122, the limiting groove 1122 extends from the side of the opening 11a towards the non-mounting 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, the limiting portion 125 is at least partially located in the limiting groove 1122 and abuts against the limiting wall 112a. In this way, during the assembly of the driving member 11 and the transmission assembly 12, the driving member 11 and the transmission assembly 12 can be limited in the axial direction by the cooperation between the limiting groove 1122 and the limiting portion 125, so that the driving member 11 can be accurately sleeved on the specified position of the transmission assembly 12 along the rotation axis, thereby facilitating the assembly of the knob 1.

[0053] In some embodiments, the limiting groove 1122 is annularly arranged, which ensures 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 step of aligning the limiting groove 1122 and the limiting portion 125 during the assembly of the driving member 11 and the transmission assembly 12, and thereby improving the assembly efficiency of the knob 1.

[0054] Please refer to Figures 2 to 3In some embodiments, the inner surface of the mounting section 112 is provided with a limiting protrusion 1121 which can cooperate with at least part of the outer wall of the transmission assembly 12 to limit the radial movement of the transmission assembly 12. In the case of the driving member 11 being at least partially annular, the entire annular driving member 11 can not be of equal diameter due to manufacturing process. In this case, the limiting protrusion 1121 can reduce the gap between the mounting section 112 and the transmission assembly 12, thereby reducing the radial error between the annular driving member 11 and the transmission assembly 12, and limiting the radial movement of the transmission assembly 12, so as to avoid the relative radial movement between the annular driving member 11 and the transmission assembly 12 during the rotation of the annular driving member 11, and thereby improve the transmission stability between the transmission assembly 12 and the annular driving member 11.

[0055] In some embodiments, the distance between the limiting protrusion 1121 and the opening 11a is less than the distance between the end of the transmission assembly 12 extending into the driving member 11 and the opening 11a.

[0056] The limiting protrusion 1121 can be annular or composed of a plurality of protrusions spaced along the circumference of the driving member 11, and the specific configuration is not limited herein.

[0057] It should be noted that the driving member 11 and the transmission assembly 12 are connected through the first connecting portion 124 and the second connecting portion 111, and the second connecting portion 111 is arranged on the inner surface of the mounting section 112. In this case, the positional relationship between the limiting protrusion 1121 and the second connecting portion 111 can be various.

[0058] For example, referring to Figure 4 the inner surface of the mounting section 112 is provided with the second connecting portion 111 which 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 the first connecting portion 124. In this case, the space in the axial direction of the driving member 11 is fully utilized, and the interference between the first connecting portion 124 and the limiting protrusion 1121 during the assembly of the transmission assembly 12 and the driving member 11 can be avoided.

[0059] For another example, referring to Figure 5The inner surface of the mounting section 112 is provided with a second connecting portion 111, and the limiting protrusion 1121 is at least partially located at one side of the second connecting portion 111 in the circumferential direction of the driving member 11. The outer wall of the transmission assembly 12 is provided with a first connecting portion 124. At this time, the space in the circumferential direction of the driving member 11 is fully utilized, so that the structure of the knob 1 is more compact, and the length of the knob 1 in the axial direction can be reduced. Preferably, the two boundaries of the second connecting 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. It can be understood that the distance between the boundary of the second connecting 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 connecting portion 111 far from the opening 11a and the opening 11a is less than or equal to the distance between the boundary of the limiting protrusion 1121 far from the opening 11a and the opening 11a. In this way, interference between the first connecting portion 124 and the limiting protrusion 1121 can be avoided during assembly of the transmission assembly 12 and the driving member 11.

[0060] When the limiting protrusion 1121 is located at one side of the second connecting portion 111 in the circumferential direction of the driving member 11, the inner surface of the mounting section 112 is further concave and 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 with the limiting protrusion 1121, so that the machining of the limiting protrusion 1121 is facilitated.

[0061] Specifically, please refer to Figure 1 , Figure 4 and Figure 6 One of the first connecting portion 124 and the second connecting portion 111 comprises a buckling groove 124a, and the other of the first connecting portion 124 and the second connecting portion 111 comprises a buckling portion 111a, and the buckling portion 111a is adapted to be buckled and matched with the buckling groove 124a. In this way, the transmission connection between the transmission assembly 12 and the driving member 11 can be realized by buckling and matching the buckling portion 111a with the buckling groove 124a, so that the assembly of the knob 1 is facilitated.

[0062] During assembly of the knob 1, the driving member 11 can be moved along the rotation axis relative to the transmission assembly 12 to buckle and match the buckling portion 111a with the buckling groove 124a, or the driving member 11 can be rotated in the circumferential direction relative to the transmission assembly 12 to buckle and match the buckling portion 111a with the buckling groove 124a, which is not specifically limited here.

[0063] Further, please refer to Figure 6The one of the first connecting part 124 and the second connecting part 111, which is provided with the buckling groove 124a, is further provided with a mounting channel 124b, which extends along the rotation axis of the knob 1 and is located on one side of the buckling groove 124a in the circumferential direction of the transmission assembly 12. It can be understood that when the mounting channel 124b and the buckling groove 124a are provided on the transmission assembly 12, the mounting section 112 is provided with the buckling part 111a. When the mounting channel 124b and the buckling groove 124a are provided on the mounting section 112, the transmission assembly 12 is provided with the buckling part 111a.

[0064] During the assembly of the transmission assembly 12 and the driving member 11, the buckling part 111a can extend into the mounting channel 124b along the rotation axis, and the transmission assembly 12 can rotate relative to the driving member 11, so that the buckling part 111a is buckled and matched with the buckling groove 124a. It should be noted that one end of the mounting channel 124b needs to be in communication with the opening 11a, so that the buckling part 111a can extend into the mounting channel 124b along the rotation axis.

[0065] In this way, by providing the mounting channel 124b extending along the rotation axis, the mounting channel 124b can guide the buckling part 111a to move along the rotation axis during the assembly of the transmission assembly 12 and the driving member 11, so that the driving member 11 can be sleeved on the transmission assembly 12 along the rotation axis, and then only the relative rotation of the driving member 11 and the transmission assembly 12 is needed to buckle and match the buckling part 111a with the buckling groove 124a, so as to fixedly connect the driving member 11 and the transmission assembly 12, thereby facilitating the assembly of the knob 1.

[0066] The buckling part 111a can be formed by a protrusion, which is buckled and matched with the buckling groove 124a, at this time, the surface of the mounting channel 124b close to the mounting section 112 is provided with a avoiding hole for the buckling part 111a to extend into the mounting channel 124b; the buckling part 111a can also be provided in a hook shape to have a connecting part and a protrusion, at this time, the outer wall surface of the transmission assembly 12 is further provided with an avoiding channel, which is located on the same side of the buckling groove 124a in the mounting channel 124b in the circumferential direction of the transmission assembly 12, and which is in communication with the mounting channel 124b and the buckling groove 124a, when the transmission assembly 12 and the driving member 11 rotate relative to each other, the connecting part rotates in the avoiding channel, and the protrusion buckles into the buckling groove 124a, which will not be listed one by one here.

[0067] It should be noted that after the knob 1 is assembled, the buckle part 111a is buckled and matched with the buckle groove 124a, and the driving part 11 drives the transmission assembly 12 to rotate through the cooperation of the buckle part 111a and the buckle groove 124a. There are many ways to prevent the buckle part 111a from exiting the buckle groove 124a, for example, when the distance between the wall surface of the buckle 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 buckle groove 124a is communicated with the mounting channel 124b, and a step formed between the wall surface of the buckle groove 124a facing the inner surface of the mounting section 112 and the wall surface of the mounting channel 124b facing the inner surface of the mounting section 112 abuts against the buckle part 111a. For another example, a limiting protrusion 124d is arranged between the buckle groove 124a and the mounting channel 124b, and the limiting protrusion 124d abuts against the buckle part 111a to prevent the buckle part 111a from exiting, which will not be listed one by one here.

[0068] Considering that the thickness of the driving part 11 at the mounting section 112 is small, if the inner surface of the mounting section 112 is concave to form the mounting channel 124b and the buckle groove 124a, the thickness of the driving part 11 at the mounting channel 124b and the buckle groove 124a is smaller, which causes the strength of the driving part 11 at the mounting section 112 to be insufficient. In view of this, please refer to Figure 1 , Figure 4 and Figure 6 , the second connecting part 111 includes the buckle part 111a, the first connecting part 124 includes the mounting channel 124b and the buckle groove 124a, so that the strength of the driving part 11 at the inner surface of the mounting section 112 can be improved through the buckle part 111a, and the driving part 11 is a metal part, which is convenient for processing the buckle part 111a.

[0069] Further, please refer to Figure 6 , the first connecting part 124 further includes a limiting protrusion 124d, the limiting protrusion 124d is located between the buckle groove 124a and the mounting channel 124b, and the limiting protrusion 124d is adapted to abut against the buckle part 111a to prevent the buckle part 111a from exiting the buckle groove 124a when the transmission assembly 12 is buckled with the driving part 11. In this way, the buckle part 111a can be more stably buckled and matched with the buckle groove 124a, and the driving part 11 can drive the transmission assembly 12 to rotate through the cooperation of the buckle part 111a, the buckle groove 124a and the limiting protrusion 124d, so that the driving part 11 can better drive the transmission assembly 12 to rotate.

[0070] Specifically, please refer to Figure 6The mounting channel 124b has a first depth in the radial direction, the buckle groove 124a has a second depth in the radial direction, the first depth is greater than the second depth, and the mounting channel 124b has a slope 124e extending from the mounting channel bottom wall 124c to the buckle groove 124a. The limiting protrusion 124d is provided with a guide surface 124f close to one side of the mounting channel 124b, and at least part of the slope 124e and the guide surface 124f are coplanar. In this way, when the transmission assembly 12 rotates relative to the driving member 11, the buckle part 111a abuts against the guide surface 124f to guide the buckle part 111a to pass through the limiting protrusion 124d and buckle into the buckle groove 124a, thereby facilitating the assembly of the knob 1.

[0071] Further, referring to Figure 4 The buckle part 111a is provided with a guide slope 111b at one end in the circumferential direction of the transmission assembly 12; wherein, during the assembly of the transmission assembly 12 and the driving member 11, the guide slope 111b cooperates with the guide surface 124f to guide the buckle part 111a to buckle into the buckle groove 124a. In this way, the guide slope 111b cooperates with the guide surface 124f to guide the buckle part 111a to pass through the limiting protrusion 124d and buckle into the buckle groove 124a, thereby facilitating the assembly of the knob 1. It can be understood that the guide slope 111b and the guide surface 124f are inclined in the same direction, so that the contact area of the guide slope 111b and the guide surface 124f is increased during the assembly of the transmission assembly 12 and the driving member 11, thereby improving the guiding effect of the guide slope 111b and the guide surface 124f.

[0072] Referring to Figure 6 In some embodiments of the present application, the distance from the top of the buckle part 111a to the inner surface of the mounting section 112 is less than the distance from the wall surface of the mounting channel 124b facing the inner surface of the mounting section 112 to the inner surface of the mounting section 112, that is, or the radial height of the buckle part 111a is less than the depth of the mounting channel 124b. In this way, during the assembly of the transmission assembly 12 and the driving member 11, there is a gap between the buckle part 111a and the wall surface of the mounting channel 124b facing the inner surface of the mounting section 112, thereby reducing the friction between the buckle part 111a and the mounting channel 124b, and facilitating the assembly of the knob 1.

[0073] Referring to Figure 7In some embodiments of the present application, the knob 1 is provided with a plurality of sets of mounting channels 124b, buckling grooves 124a and buckling portions 111a, which are arranged 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 plurality of sets of mounting channels 124b, buckling grooves 124a and buckling portions 111a cooperate to allow the driving member 11 to be better sleeved on the transmission assembly 12 along the rotation axis, thereby facilitating the assembly of the knob 1.

[0074] Referring to Figure 3 In some embodiments of the present application, the outer wall of the driving member 11 is provided with a plurality of spaced anti-skid protrusions 114. 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.

[0075] Referring to Figure 7 In some embodiments of the present application, the transmission assembly 12 includes a connecting structure 122 and a main body structure 121, the connecting structure 122 is adapted to be in transmission connection with the driving member 11 and rotates with the driving member 11, the connecting structure 122 is provided with a sensed member 123, the main body structure 121 is at least partially mounted on the shell of the clothes treatment apparatus, and the main body 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 connecting structure 122 drives the sensed member 123 to rotate relative to the sensing member 1211, 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 provide other components to drive the sensed member 123 to rotate, which simplifies the structure of the knob 1.

[0076] The connecting structure 122 can be made of metal material, or can be made of plastic material, which is not specifically limited here. Preferably, the connecting structure 122 is a plastic part, which can reduce the cost of the knob 1, and can also avoid affecting the sensing member 1211 and the sensed member 123. The sensing member 1211 and the sensed member 123 can be a magnetic ring and a Hall sensor, or can be an infrared emitter and an infrared sensor, which is not specifically limited here.

[0077] There are many ways to install the main body structure 121 on the shell, and the main body structure 121 can be installed on the shell by screw connection, or can be installed on the shell by buckling cooperation, which is not specifically limited here.

[0078] The main body structure 2 includes a connecting part 1212 connected at least partially to a housing of the laundry treating apparatus.
