[0044] In the related art, the display area and control interaction of most washing machines on the market are set on the control panel. The main interaction method is to directly touch and select the program or to select the desired program by rotating the knob. As the functions of washing machines increase, the interaction with washing machines is becoming more and more complicated. Currently, the knob on the washing machine is a major interactive component. Most of them are simple ordinary plastic knobs that are only used for rotating to select programs. Therefore, display knob assemblies that integrate display and interactive operations are gradually being applied to washing machines. The display knob assembly installed on the control panel needs to maximize the display area within the limited space to improve the user experience. In addition, due to the diverse usage environments of washing machines, the knob assembly with display function is subject to the problem of water ingress or water mist condensation affecting the circuit and display. Therefore, waterproofing is also an issue that must be considered for knobs with display functions.

[0045] The present invention provides a knob assembly and a clothes processing device to solve the problem of limited display area of the existing knob assembly. Figure 1-7 Provide explanation.

[0046] The knob assembly provided in the embodiment of the present application is referred to as Figure 1 and Figure 2 As shown, it includes a base 100, a display structure 200 and a knob screen 300. The display structure 200 is installed on the base 100. The display structure 200 is provided with a glue dispensing groove 201, and the glue dispensing groove 201 contains an adhesive layer; the knob screen 300 is bonded to the display structure 200 through the adhesive layer.

[0047] It can be understood that in this embodiment, the base 100 is used to provide a stable support platform for the display structure 200 and the knob screen 300. The display structure 200 is used to display content. The display structure 200 is installed on the base 100 to display information or images. The knob screen 300 can be made of transparent or translucent materials, such as glass, so that the user can clearly see the content on the display structure 200 through the knob screen 300.

[0048] Furthermore, the display structure 200 is provided with a dispensing groove 201 for accommodating an adhesive layer. That is, the knob screen 300 and the display structure 200 are connected by dispensing glue. This dispensing connection allows for a tighter fit between the knob screen 300 and the display structure 200, eliminating the need to reserve additional space for the snap-fit structure. This significantly reduces the overall assembly space and allows for a more compact knob assembly. By eliminating the space occupied by mechanical connectors such as snaps, the display area of the knob screen 300 and the display structure 200 can be designed to be larger, thereby providing a richer display of information and enhancing the user experience.

[0049] For example, the adhesive dispensing groove 201 can be arranged along the circumference of the display structure 200 to form a complete ring, thereby improving the sealing and waterproof performance of the display structure 200. When the knob screen 300 is placed and pressed against the display structure 200, the adhesive layer will evenly expand along the guidance of the annular adhesive dispensing groove 201, filling the space within the groove and tightly fitting between the contact surface between the knob screen 300 and the display structure 200, effectively preventing moisture, dust, and other external contaminants from infiltrating from the edges into the interior of the display structure 200, thereby protecting the electronic components inside the display structure 200 from damage and preventing water ingress or water mist condensation from affecting the circuit and display.

[0050] The knob assembly provided in the embodiment of the present application includes a base 100, a display structure 200, and a knob screen 300. The display structure 200 is mounted on the base 100 and provided with a glue dispensing groove 201 for receiving an adhesive layer. The knob screen 300 is bonded to the display structure 200 via the adhesive layer. The glue dispensing method of connecting the knob screen 300 and the display structure 200 significantly reduces the space occupied by the entire assembly compared to traditional methods such as snap-on connections. The display area of the knob screen 300 can be designed to be as large as possible, improving the user experience.

[0051] According to one embodiment of the present application, the display structure 200 includes a digital tube 210, which is installed on the base 100, and a glue groove 201 is opened on the digital tube 210. The knob screen 300 is bonded to the digital tube 210 through an adhesive layer, which can firmly fix the knob screen 300 on the digital tube 210 and has good support stability.

[0052] According to one embodiment of the present application, Figure 1 、 Figure 2 and Figure 3 As shown, the display structure also includes a display light board 220, and a light guide hole 211 is opened on the digital tube 210. The display light board 220 is located on the side of the digital tube 210 away from the knob screen 300. The light emitted by the display light board 220 is suitable for passing through the light guide hole 211 for display.

[0053] It can be understood that in this embodiment, a plurality of light-emitting elements (such as LED lamp beads) are installed on the display light board 220, and a plurality of light-guiding holes 211 are opened on the digital tube 210. The size, shape and position of the light-guiding holes 211 can be set as needed so that the light in the display light board 220 can pass through and display a specific shape. The display light board 220 is the control part of the display structure 200, which can receive the electrical signal of the controller and control the display content.

[0054] For example, a display film 230 is provided on the side of the digital tube 210 close to the knob screen 300, and icons, text or symbols corresponding to the parameter information are provided on the display film 230. The position and shape of the light guide hole 211 in the digital tube 210 correspond one-to-one to the display content on the display film 230.

[0055] The display film 230 mainly serves to decorate and enhance the display effect. It can improve the user's perception and understanding of the displayed information through visual guidance and emphasis. For example, if the digital tube 210 is used to display the number "1", a bold or highlighted "1" pattern can be set at the corresponding position on the display film 230.

[0056] According to one embodiment of the present application, Figure 4 As shown, a glue layer 110 is provided in the gap between the digital tube 210 and the base 100 , and the glue layer 110 is provided along the circumference of the base 100 .

[0057] In this embodiment, the glue layer 110 directly fills the tiny gap between the digital tube 210 and the base 100. Compared with traditional snap-on connection methods, the seamless connection method of the glue layer 110 greatly saves space, making the entire knob assembly more compact, and can maximize the area of the display area, providing users with a larger visual information display space.

[0058] The glue potting layer 110 is arranged along the circumference of the base 100, forming a complete waterproof barrier between the base 100 and the digital tube 210. The circumferential sealing design can effectively prevent external substances such as moisture and dust from entering the gap between the digital tube 210 and the base 100, thereby protecting the internal electronic components from damage.

[0059] Optionally, the material of the glue potting layer 110 can be vulcanized silicone. Vulcanized silicone has good sealing performance and certain elasticity, and can absorb some vibration and impact, thereby playing a certain protective role for the digital tube 210.

[0060] According to one embodiment of the present application, Figure 2 As shown, the digital tube 210 is provided with at least one positioning post 212 along the circumference, and the base 100 is provided with a positioning groove 120 that cooperates with the positioning post 212. The positioning post 212 is passed through the positioning groove 120, so that the digital tube 210 can be accurately aligned and fixed on the base 100 during installation, preventing displacement or loosening during use or installation, improving the installation accuracy of the digital tube 210, and ensuring that the digital tube 210 can present clear and accurate images or numbers when displaying.

[0061] Optionally, there are multiple positioning posts 212, and the multiple positioning posts 212 are spaced apart along the circumference of the digital tube 210. The arrangement of multiple positioning posts 212 provides multiple positioning support points for the digital tube 210, ensuring the positioning accuracy of the digital tube 210 during installation and improving the durability and reliability of the connection between the digital tube 210 and the base 100. Furthermore, the multiple positioning posts 212 are spaced apart along the circumference, which helps achieve a balanced layout between the digital tube 210 and the base 100 and ensures stable installation of the digital tube 210.

[0062] According to one embodiment of the present application, Figure 1 and Figure 5 As shown, the base 100 is provided with a first threaded hole 130 , the digital tube 210 is provided with a second threaded hole 213 , and the knob assembly further includes a screw 140 , which is threadedly connected to the first threaded hole 130 and the second threaded hole 213 to fix the digital tube 210 and the base 100 .

[0063] In this embodiment, the digital tube 210 and the base 100 can be fastened together by a screw 140 after positioning is completed. The first threaded hole 130 and the second threaded hole 213 are coaxially arranged, and the screw 140 is threadedly connected to the first threaded hole 130 and the second threaded hole 213 to firmly fix the digital tube 210 on the base 100. This fastening method is not only simple and fast, but also has high connection strength and stability, and is also convenient for subsequent disassembly and maintenance.

[0064] In an optional embodiment, the number of the first threaded holes 130 and the second threaded holes 213 are both multiple, the first threaded holes 130 and the second threaded holes 213 are arranged in a one-to-one correspondence, and the first threaded holes 130 and the second threaded holes 213 are respectively arranged at circumferential intervals along the knob assembly, further enhancing the connection strength and stability between the digital tube 210 and the base 100.

[0065] According to one embodiment of the present application, Figure 1 、 Figure 2 and Figure 6 As shown, the knob assembly also includes a rotating module 400, which includes a knob rotor 410, a knob outer ring 420 and a knob pointer 430. The knob rotor 410 is rotatably mounted on the base 100; the knob outer ring 420 is sleeved on the knob outer ring 420, and the knob outer ring 420 is located on the outside of the display structure 200. The knob pointer 430 is installed on the outside of the knob outer ring 420 to indicate the user's target selection procedure.

[0066] It will be appreciated that in this embodiment, the knob assembly integrates both knob operation and display functions. The knob rotor 410 is rotatably mounted on the base 100. Specifically, the knob rotor 410 can be rotatably connected to the base 100 via structures such as bearings and sleeves. The knob outer ring 420 is sleeved on the outside of the knob rotor 410 and is fixedly connected to the knob rotor 410. The knob outer ring 420 provides a comfortable gripping surface for the user. When the user rotates the knob outer ring 420, the knob rotor 410 rotates accordingly. The knob pointer 430 is mounted on the outside of the knob outer ring 420 and is fixed to the knob outer ring 420. It is used to indicate the target program, parameter value, or position currently selected or adjusted by the user. As the knob outer ring 420 rotates, the knob pointer 430 moves accordingly, pointing to the corresponding position or scale on the appliance, such as a washing machine, thereby providing intuitive visual feedback to the user.

[0067] The color of the knob pointer 430 can be set to be different from that of the knob outer ring 420 to increase recognition, facilitate users to determine the direction of the knob pointer 430, reduce misoperation, save time and improve operating efficiency.

[0068] Optionally, the knob pointer 430 can be fixed to the knob outer ring 420 by riveting. Through the riveting action, a tight connection is formed between the knob pointer 430 and the knob outer ring 420, which is not easy to loosen or fall off. The riveting fixation method does not require additional connectors or space, which helps to maintain the compactness of the knob assembly. Optionally, the knob pointer 430 can also be connected to the knob outer ring 420 by a fixing pin.

[0069] According to one embodiment of the present application, Figure 1 and Figure 5 As shown, the knob rotor 410 is provided with at least one first clamping portion 411 along the circumferential direction, and the knob outer ring 420 is provided with a second clamping portion 421. The first clamping portion 411 is engaged with the second clamping portion 421 to fix the knob outer ring 420 and the knob rotor 410.

[0070] In this embodiment, the knob outer ring 420 and the knob rotor 410 are fixedly connected by the snap-fitting cooperation of the first snap-fitting portion 411 and the second snap-fitting portion 421, ensuring that the knob rotor 410 can be driven to rotate synchronously when the knob outer ring 420 rotates. The snap-fitting design facilitates the disassembly and replacement of the knob outer ring 420, thereby improving the maintainability of the knob module.

[0071] Optionally, the first clamping portion 411 and the second clamping portion 421 can be a clamping slot and a buckle that cooperates with the clamping slot. The clamping slot can be set on the inner side of the knob outer ring 420, and the buckle can be set on the outer side of the knob rotor 410.
