[0046] An embodiment of the present application provides a knob assembly 1 , which includes an electronic control assembly 13 , a knob 11 and a transmission structure 12 , as shown in FIG1 , FIG3 and FIG4 .

[0047] The user can hold the knob 11 and drive the knob 11 to rotate.

[0048] Transmission structure 12 is designed to rotate with knob 11, triggering electronic control component 13 to generate an electrical signal. In other words, transmission structure 12 is a passive component; rotation of knob 11 drives transmission structure 12 along with it. When transmission structure 12 rotates with knob 11, it triggers electronic control component 13 to generate an electrical signal.

[0049] Please refer to Figures 4, 5 and 6. The knob 11 includes a ring body 111 and a connecting structure 112 provided on the ring body 111. The knob 11 is connected to the transmission structure 12 via the connecting structure 112.

[0050] The ring body 111 is generally annular in shape.

[0051] At least one of the ring body 111 and the connecting structure 112 is a metal member. For example, in some embodiments, the ring body 111 is a metal member and the connecting structure 112 is also a metal member. In other embodiments, the ring body 111 is a metal member and the connecting structure 112 is a non-metallic member. In still other embodiments, the ring body 111 is a non-metallic member and the connecting structure 112 is a metal member.

[0052] In the related art, the knob is made of plastic as a whole, and a damping structure is set at the rotation center of the knob to obtain a damping feel. However, the damping force arm at the rotation center is small, and a significant damping force needs to be set to obtain the damping feel. In addition, the friction resistance of the knob during rotation is relatively large, and the components are prone to wear. When the wear of the components reaches a certain level, the damping feel will be reduced or even disappear.

[0053] Compared with plastic parts of the same size, the knob assembly 1 in the embodiment of the present application has a higher density of metal parts, so the knob assembly 1 is heavier, giving it a heavy feel and improving the user experience. In addition, the heavy feel is achieved through the weight of the knob assembly 1 itself, without the need for friction damping, reducing the wear of components and increasing the service life of the knob assembly 1.

[0054] In some specific embodiments, the ring body 111 is metal, and the connecting structure 112 is non-metallic. In this embodiment, the non-metallic connecting structure 112 connects to the transmission structure 12, eliminating the need to machine the connecting structure 112 on the ring body 111 to meet assembly precision requirements. This reduces manufacturing requirements for the ring body 111, conserves materials, and reduces costs. Only the connecting structure 112 needs to be manufactured to the designed shape. Therefore, the knob assembly 1 of this embodiment of the present application provides a substantial feel while also balancing manufacturing costs and process requirements.

[0055] In the embodiments of the present application, non-metallic materials are a general term for materials other than metal materials. Non-metallic materials may include plastics, polymer materials, etc.

[0056] Exemplarily, the transmission structure 12 is a plastic part. In some embodiments, the transmission structure 12 is an integrated plastic part.

[0057] The connection method between the ring body 111 and the connection structure 112 is not limited, for example, bonding, welding, etc.

[0058] For example, in some embodiments, the connecting structure 112 is a plastic part, the ring body 111 is a metal part, and the ring body 111 and the connecting structure 112 are injection molded into an integral structure. For example, during the manufacturing process, after the ring body 111 is processed, the ring body 111 is placed in an injection mold, and molten resin is injected into the injection mold. After the mold is opened, the resin cools to form the connecting structure 112, and the resin and the ring body 111 are combined together, without the need for other fasteners for connection.

[0059] The specific connection method between the connection structure 112 and the transmission structure 12 is not limited.

[0060] Illustratively, one of the transmission structure 12 and the connecting structure 112 is provided with a plurality of slots 12a (see FIG8 ), while the other is provided with a plurality of hooks 1122 (see FIG6 ). The plurality of hooks 1122 are arranged along the circumference of the ring body 111, and the hooks 1122 engage with the slots 12a. For example, in some embodiments, the transmission structure 12 is provided with the hooks 1122, and the connecting structure 112 is provided with the slots 12a. In other embodiments, the transmission structure 12 is provided with the slots 12a, and the connecting structure 112 is provided with the hooks 1122. In some other embodiments, a portion of a hook 1122 and a portion of a slot 12a are provided on the transmission structure 12, and another portion of a hook 1122 and another portion of a slot 12a are provided on the connecting structure 112. The hook 1122 on the connecting structure 112 is engaged with the slot 12a on the transmission structure 12, and the slot 12a on the connecting structure 112 is engaged with the hook 1122 on the transmission structure 12.

[0061] In this embodiment, the hook 1122 cooperates with the slot 12a to achieve quick connection without the need for special tools, making assembly simple and quick.

[0062] For example, along the axial direction of the ring body 111, the hook 1122 does not extend beyond the axial end surfaces of the ring body 111 at opposite ends. This reduces the interference of the hook 1122 with the axial direction of the ring body 111, allows the ring body 111 to be as close as possible to the mounting surface 2c (see FIG. 11 ) for mounting the knob assembly 1, and reduces the axial clearance between the ring body 111 and the mounting surface 2c, resulting in a more aesthetically pleasing appearance.

[0063] In some embodiments, the end of the transmission structure 12 that is connected to the ring body 111 is located radially inward of the ring body 111. In other words, the ring body 111 surrounds the end of the transmission structure 12 that is close to the ring body 111, so that the transmission structure 12 is not exposed radially outside the ring body 111. In this way, the transmission structure 12 does not affect the appearance of the knob assembly 1, which helps to improve the aesthetic appearance of the knob assembly 1.

[0064] In other embodiments, one end of the transmission structure 12 for connecting with the ring body 111 is located radially outside the ring body 111 , that is, at least a portion of the transmission structure 12 surrounds the radial outside of the ring body 111 .

[0065] In some embodiments, in which the ring body 111 and the connecting structure 112 are injection-molded into an integral structure, as shown in Figures 6 and 7 , the ring body 111 is provided with a receiving groove 111a, into which at least a portion of the connecting structure 112 is filled. The receiving groove 111a increases the contact area and bonding strength between the plastic and the metal, thereby reducing the probability of axial loosening of the connecting structure 112 and the ring body 111.

[0066] The specific shape of the receiving groove 111 a is not limited.

[0067] For example, referring to Figures 6 and 7 , accommodating groove 111a is an annular groove surrounding ring body 111, i.e., accommodating groove 111a is connected end to end, and the central angle corresponding to accommodating groove 111a is 360°. Connecting structure 112 includes connecting ring 1121, which is filled in the annular groove. During the injection molding process, the molten resin poured into accommodating groove 111a forms connecting ring 1121 after cooling and molding. In this embodiment, the structural form of connecting ring 1121 can enhance the structural strength of connecting structure 112, thereby improving reliability.

[0068] It is understandable that when the connection structure 112 is provided with a slot 12 a, the slot 12 a can be formed on the connection ring 1121 . When the connection structure 112 is provided with hooks 1122 , each hook 1122 is connected to the connection ring 1121 .

[0069] It should be noted that in the embodiment where the end of the transmission structure 12 for connection with the ring body 111 is located radially inward of the ring body 111, the accommodating groove 111a is provided on the circumferential inner surface of the ring body 111. In the embodiment where the end of the transmission structure 12 for connection with the ring body 111 is located radially outward of the ring body 111, the accommodating groove 111a is provided on the circumferential outer surface of the ring body 111.

[0070] For example, referring to Figures 6 and 7 , a spiral groove 111b is provided on the radial side of the ring body 111. This spiral groove 111b extends in a spiral direction around the groove wall, and a portion of the connecting ring 1121 is filled in the spiral groove 111b. This spiral groove 111b further strengthens the injection molding bond between the plastic and metal, improving reliability.

[0071] It should be noted that the dimension of the spiral groove 111b along the axial direction of the ring body 111 is smaller than the dimension of the annular groove along the axial direction. For example, the dimension of the spiral groove 111b along the axial direction of the ring body 111 is 1 / 3 to 1 / 6 of the dimension of the annular groove along the axial direction.

[0072] Exemplarily, the radial dimension of the spiral groove 111 b along the ring body 111 is smaller than the radial dimension of the annular groove, so as to reduce the influence of the spiral groove 111 b on the structural strength of the ring body 111 .

[0073] For example, referring to Figure 7 , any one of the groove walls of the annular groove is provided with at least one recess 111c, and at least a portion of the connecting ring 1121 is filled in the recess 111c. For example, recesses 111c are provided on the axial sidewalls of the annular groove and / or the radial sidewalls of the annular groove. Referring to Figure 6 , the structure filled in recess 111c forms a protrusion 11211. The combination of protrusion 11211 and recess 111c can prevent relative rotation between the connecting structure 112 and the ring body 111. It should be noted that during the injection molding process, the molten resin poured into the recess 111c forms the protrusion 11211 after cooling and molding.

[0074] The number of the pits 111c is not limited, and may be one, or two or more.

[0075] In some embodiments, a pattern structure 1111 is provided on the radial outer side of the ring body 111, for example, knurling, which can increase the friction when the user's hand contacts the ring body 111, reduce the chance of finger slipping, improve the feel, and also have a better aesthetic effect.

[0076] In some embodiments, the ring body 111 is a metal part, please refer to Figure 3, the radial thickness d of the ring body 111 is 1.5mm~6mm, that is, 1.5mm≤d≤6mm (millimeters), for example, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 6mm; and / or, the weight of the ring body 111 is 20g~100g, for example, 20g, 30g, 40g, 50g, 60g, 70g, 80g, 90g, 100g, etc.

[0077] The radial thickness d of the ring body 111 refers to the thickness of the thickest portion of the ring body 111 along the radial direction.

[0078] In this embodiment, the radial thickness of the ring body 111 can ensure that the ring body 111 has appropriate structural strength and is not easily deformed during the processing.

[0079] The weight of the ring body 111 can make the ring body 111 have a good thick feel and better conform to ergonomics.

[0080] In the embodiment where the ring body 111 is a metal member, the material of the ring body 111 may be, for example, aluminum alloy, zinc alloy, stainless steel, etc.

[0081] In some embodiments, referring to FIG. 2 , the outer diameter D of the ring body 111 is 30 mm to 100 mm, with 30 mm ≤ D ≤ 100 mm, for example, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, etc. This outer diameter range is convenient for human hand gripping, conforms to ergonomics, and enhances user experience.

[0082] For example, referring to Figures 1 and 3 , the knob assembly 1 includes a window cover 14, which is disposed within the ring body 111 and remains stationary relative to the electronic control assembly 13. That is, the knob 11 does not cause the window cover 14 to rotate; during the rotation of the knob 11, the knob 11 and the window cover 14 move relative to each other.

[0083] The material of the window cover 14 is not limited, for example, it can be light-transmitting plastic.

[0084] 3 , the knob assembly 1 includes a display assembly 15 , which is disposed inside the ring body 111 and located on the side of the window cover 14 facing the electronic control assembly 13 . That is, the ring body 111 surrounds the display assembly 15 .

[0085] The display assembly 15 is used to display information; the window cover 14 is used to see through the information displayed by the display assembly 15.

[0086] The type of information displayed by the display component 15 is not limited, for example, it can be text, pattern, symbol, etc., which is not limited here.

[0087] The type of the display component 15 is not limited, and may be, for example, an OLED (Organic Light-Emitting Diode) component.

[0088] In some embodiments, referring to FIG. 3 , the knob assembly 1 further includes an LED assembly 16 having at least one light source. The portion of the window cover 14 corresponding to the light source of the LED assembly 16 may be preset with text or patterns. When the light source is turned on, the corresponding text area or pattern area on the window cover 14 may appear highlighted.

[0089] The specific type of the electronic control component 13 is not limited.

[0090] For example, referring to FIG3 , the electronic control assembly 13 includes a circuit board 131 and an encoder 132 electrically connected to the circuit board 131. The circuit board 131 is disposed on one axial side of the ring body 111, and the encoder 132 is disposed on the side of the circuit board 131 facing the knob 11. Specifically, the encoder 132 is located between the circuit board 131 and the window cover 14.

[0091] 3 and 8 , the transmission structure 12 has a through hole 12b through which the encoder 132 is disposed. As the transmission structure 12 rotates with the knob 11, the transmission structure 12 can trigger the encoder 132 at different angles, generating different electrical signals depending on the rotation angle of the ring body 111.

[0092] The encoder 132 may adopt any suitable structure in the prior art, which will not be described in detail here.

[0093] The application scenarios of the knob assembly 1 in the embodiment of the present application are not limited, for example, household appliances.

[0094] The embodiment of the present application is described by taking the application of the knob assembly 1 in a clothing processing device as an example.

[0095] An embodiment of the present application provides a clothing processing device, including a housing, a drum assembly, a control device, and a knob assembly 1 of any embodiment of the present application.

[0096] The shell serves as the exterior part of the clothing processing device.

[0097] The barrel assembly is arranged in the shell and has a clothes processing chamber.

[0098] The type of the clothes processing apparatus is not limited, for example, it can be a drum-type clothes processing apparatus, that is, the axis of the drum assembly is arranged substantially along the front-to-back direction.

[0099] The knob assembly 1 is arranged on the housing.

[0100] The electronic control assembly 13 is electrically connected to the control device, that is, signals can be transmitted between the two. The control device is used to select a corresponding washing program and / or adjust washing parameters according to the electrical signals generated by the electronic control assembly 13.

[0101] In some embodiments, the clothing processing device may be a dryer or a washer-dryer. In this embodiment, the knob assembly 1 is disposed on the housing, and the electronic control assembly 13 is electrically connected to the control device, i.e., signals can be transmitted therebetween. The control device is configured to select a corresponding drying program and / or adjust drying parameters based on the electrical signals generated by the electronic control assembly 13.

[0102] For example, the user selects the corresponding washing program and washing parameters by rotating the knob 11. Specifically, taking the selection of the washing program as an example, when the user rotates the knob 11, it rotates at different angles, and the electronic control component 13 generates different electrical signals. Different electrical signals correspond to different washing programs. The control device controls the clothing processing equipment to enter the corresponding washing program according to different electrical signals.

[0103] For example, referring to Figures 9, 10 and 11, the housing includes a box body and a control panel 2, which is disposed on the box body. For example, the top side of the front plate of the box body has a vacancy, and the control panel 2 is disposed in the vacancy.

[0104] Referring to Figure 11 , a portion of the control panel 2 is recessed toward the interior of the housing, forming a recessed cavity 2a. The electronic control assembly 13 is disposed within the recessed cavity 2a, and the knob 11 covers the recessed cavity 2a. In other words, the projection of the knob 11 on the panel of the control panel 2 overlaps the projection of the recessed cavity 2a, making the recessed cavity 2a virtually invisible to the user.

[0105] It can be connected that the cavity wall of the recessed cavity 2a is provided with a through hole 2b for passing the cable of the electronic control component 13.
