[0046] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0047] Please see Figure 1 This application provides a knob assembly 1000 and a garment processing device. The garment processing device includes the knob assembly 1000 and a housing. The housing includes a panel. The housing can be made of various materials, including metal and plastic, without specific limitations. The housing typically has a mounting cavity for mounting the functional components of the garment processing device. The panel can be integrally formed with the housing, or it can be detachably connected to the housing, without specific limitations.

[0048] Please refer to the following: Figures 1 to 3 The knob assembly 1000 includes a mounting member 100, a knob 200, and a first water-guiding rib 300. The mounting member 100 includes a panel; it should be noted that the panel is part of the mounting member 100 and also part of the housing. The mounting member 100 has a mounting hole 110, which can be circular or square, without specific limitation. Preferably, the mounting hole 110 is circular, which reduces the gap between the knob 200 and the mounting hole 110, thereby improving the waterproof performance of the knob assembly 1000.

[0049] It should be noted that the mounting component 100 is located on the side of the housing, and the axis of the mounting hole 110 is set at an angle to the vertical direction. In this configuration, water on the mounting component 100 will only flow from top to bottom under the influence of gravity. Please refer to [link / reference]. Figure 2 The axis of the mounting hole 110 is perpendicular to the vertical direction.

[0050] Please see Figure 2 The knob 200 extends at least partially into the mounting hole 110 and connects with the wall of the mounting hole 110. At least part of the knob 200 is located outside the mounting hole 110, forming a guide gap 400 between the knob 200 and the mounting member 100. It should be noted that the guide gap 400 between the knob 200 and the mounting member 100 means that the portion of the knob 200 outside the mounting hole 110 completely covers the mounting hole 110 axially, and the guide gap 400 communicates with the mounting hole 110. The guide gap 400 is annular. The knob 200 can rotate relative to the mounting member about its axis.

[0051] Please see Figure 3 A first water guide rib 300 is disposed on the mounting member 100, that is, the first water guide rib 300 is disposed on the panel. The first water guide rib 300 is at least partially located above the mounting hole 110 and at least partially located on the flow path formed by the flow guide gap 400, which is the path through which water flows under the action of gravity within the flow guide gap 400. The first water guide rib 300 is inclined from the direction away from the mounting member 100 toward the axis away from the knob 200, so as to guide the water flowing to the first water guide rib 300 from the flow guide gap 400 to the left and / or right side of the first water guide rib 300. It can be understood that the direction of the first water guide rib 300 away from the mounting member 100 is the direction in which the first water guide rib 300 extends along the axis of the knob 200 toward the portion of the knob 200 located outside the housing 100.

[0052] It should be noted that the water flowing from the guide gap 400 to the first guide rib 300 will be affected by the inclination of the first guide rib 300, causing it to accumulate at the end of the first guide rib 300 near the mounting part 100. Subsequently, the water will flow to the left and / or right side of the first guide rib 300 under the guidance of the first guide rib 300. The hole axis of the mounting hole 110 and the vertical direction together define the mid-plane, and the left and right sides of the first guide rib 300 are located on both sides of the mid-plane.

[0053] There are many ways to set the first water guide rib 300 on the mounting part 100. The first water guide rib 300 can be integrally formed with the mounting part 100, or it can be detachably connected to the mounting part 100. No specific limitation is made here. Preferably, the first water guide rib 300 is integrally formed with the mounting part 100. This can reduce the gap between the first water guide rib 300 and the mounting part 100, thereby improving the waterproof effect of the knob assembly 1000.

[0054] Please see Figure 3The first water guide rib 300 directs the water flowing through the guide gap 400 to the left and / or right side of the first water guide rib 300. Whether the first water guide rib 300 directs the water to the left or right depends on the direction of extension of the first water guide rib 300 in the circumferential direction of the knob 200. When the first water guide rib 300 extends from top to bottom and to the right in the circumferential direction of the knob 200, the water will flow to the right side of the first water guide rib 300 under the guidance of the first water guide rib 300; when the first water guide rib 300 extends from top to bottom and to the left in the circumferential direction of the knob 200, the water will flow to the left side of the first water guide rib 300 under the guidance of the first water guide rib 300; when the first water guide rib 300 extends from top to bottom and to the left and right sides respectively at both ends in the circumferential direction of the knob 200, the water will flow to the left and right sides of the first water guide rib 300 under the guidance of the first water guide rib 300. These are not listed in detail here. Preferably, the first water guide rib 300 extends around the pivot of the knob 200 in an arc shape, so that water can flow better along the first water guide rib 300, thereby preventing excessive water accumulation at the end of the first water guide rib 300 near the mounting part 100, which would cause water to overflow the first water guide rib 300.

[0055] In this embodiment, the knob assembly 1000 blocks water above the mounting hole 110 by setting a first water guide rib 300. The first water guide rib 300 guides the water flowing into the guide gap 400 to the left and / or right side of the first water guide rib 300. At the same time, the inclined first water guide rib 300 can prevent water from passing over the first water guide rib 300, thereby preventing water from flowing into the gap between the mounting hole 110 and the knob 200 from above the mounting hole 110, thereby improving the waterproof effect of the knob assembly 1000.

[0056] Please see Figure 3 The first water guide rib 300 is tilted at an angle b relative to the axis of the knob 200, where b ≥ 2°. This configuration allows the first water guide rib 300 to effectively collect water flowing from the guide gap 400 to the end of the first water guide rib 300 near the mounting component 100, thus preventing water from overflowing the first water guide rib 300 and consequently preventing water from flowing from above the mounting hole 110 into the gap between the mounting hole 110 and the knob 200. This improves the waterproofing effect of the knob assembly 1000.

[0057] Please see Figure 1 Considering the slope of the first water guide rib 300, and to facilitate its draft forming, the first water guide rib 300 extends around the axis of rotation of the knob 200 in an arc shape. The arc of the first water guide rib 300 in the circumferential direction of the knob 200 is 'a', where 100°≤a≤360°. This design ensures the first water guide rib 300 has sufficient length to prevent damage during drafting, thus facilitating its formation.

[0058] Furthermore, the first water guide rib 300 is symmetrically arranged along the midline. This arrangement ensures that water can flow evenly to the left and right sides of the first water guide rib 300 under its guidance, thereby preventing water from concentrating on one side of the first water guide rib 300 and thus preventing excessive water accumulation on one side of the first water guide rib 300, which could cause water to overflow the first water guide rib 300.

[0059] Preferably, the first water guide rib 300 has an arc of 180° in the circumferential direction of the knob 200, and the first water guide rib 300 is symmetrically arranged along the center plane. With this arrangement, the first water guide rib 300 partially covers the mounting hole 110, thereby preventing water guided by the first water guide rib 300 to the left and right sides from flowing into the mounting hole 110.

[0060] Please see Figure 4 In some embodiments of this application, the knob assembly 1000 further includes a second water-guiding rib 500. The second water-guiding rib 500 is disposed on the mounting member 100 and is at least partially located below the mounting hole 110, extending into the flow-guiding gap 400. The second water-guiding rib 500 connects to the first water-guiding rib 300 at both ends of the knob 200 in the circumferential direction to form an annular water-guiding rib 600. The mounting hole 110 is located inside the annular water-guiding rib 600. With this configuration, the annular water-guiding rib 600 can block water at any position in the circumferential direction of the knob 200, thereby improving the waterproof effect of the knob assembly 1000 and preventing water guided to the left and right sides by the first water-guiding rib 300 from flowing into the mounting hole 110.

[0061] Furthermore, please refer to the following: Figure 1 , Figures 3 to 4 The mounting component 100 is also provided with an annular groove 120, which is located outside the annular water guide rib 600. With this configuration, water flowing from the guide gap 400 to the first water guide rib 300 will flow into the annular groove 120 under the guidance of the outer peripheral wall of the first water guide rib 300, and then flow to the left and right sides of the first water guide rib 300 under the guidance of the first water guide rib 300. This can increase the amount of water accumulated at the end of the first water guide rib 300 near the mounting component 100. Thus, when a large amount of water enters the guide gap 400, the annular groove 120 can share some of the water volume with the first water guide rib 300 to prevent the water from overflowing the first water guide rib 300.

[0062] Considering that when a large amount of water enters the flow guide gap 400, the water will flow along the knob 200 towards the surface of the mounting panel, thus allowing water to easily pass through the gap between the knob 200 and the first water guide rib 300 and enter the mounting hole 110, please refer to the following: Figures 3 to 4The knob 200 has an annular relief groove 210 recessed on the surface facing the mounting piece 100. The first water guide rib 300 extends into the annular relief groove 210. With this configuration, water entering through the flow guide gap 400 located outside the annular relief groove 210 will first contact the first water guide rib 300. When a large amount of water enters through the flow guide gap 400, the water will flow along the surface of the knob 200 facing the mounting panel to the annular relief groove 210 and be blocked, thereby preventing water from passing through the gap between the first water guide rib 300 and the bottom of the annular relief groove 210.

[0063] Please refer to the following: Figure 1 , Figures 3 to 4 In some embodiments of this application, the knob 200 includes a mounting base 220, a rotating assembly 230, and a display module 240. The mounting base 220 is mounted in the mounting hole 110. The rotating assembly 230 is arranged in a ring and rotatably mounted on the mounting base 220. The display module 240 has a display part 241 and a mounting part 242. The mounting part 242 is located inside the rotating assembly 230. One end of the mounting part 242 is connected to the display part 241, and the other end of the mounting part 242 passes through the inner ring of the rotating assembly 230 and is mounted on the mounting base 220. With this configuration, the display module 240 can display various data of the clothing processing equipment, thereby facilitating user operation of the clothing processing equipment. At the same time, the display module 240 is located on the knob 200, making full use of the space of the knob 200 in the rotation axis.

[0064] The display module 240 can display various types of data. For example, when the garment processing device is an oven, the display module 240 can display data such as baking time and baking temperature. Similarly, when the garment processing device is a washing machine, it can display data such as washing mode and washing time. These are just a few examples. The mounting part 242 can be installed on the mounting base 220 in various ways. It can be installed using screws or by snap-fitting; no specific limitation is made here.

[0065] To prevent wear between the rotating assembly 230 and the outer peripheral wall of the display unit 241 during rotation, a gap is typically maintained between the display unit 241 and the rotating assembly 230. Therefore, please refer to [the relevant documentation / reference needed]. Figures 3 to 4 A drain outlet 236 is provided on the surface of the rotating assembly 230 facing the mounting member 100. The distance between the drain outlet 236 and the rotation axis of the knob 200 is greater than the maximum distance between the first water guide rib 300 and the rotation axis of the knob 200. A water inlet channel 237 is formed between the rotating assembly 230 and the outer peripheral wall of the display part 241, and the drain outlet 236 communicates with the water inlet channel 237. It should be noted that the gap formed between the display part 241 and the rotating assembly 230 forms the water inlet channel 237.

[0066] Understandably, the drain outlet 236 will rotate with the rotating component 230. When the drain outlet 236 rotates to the top of the first water guide rib 300, the drain outlet 236 is located on the side of the first water guide rib 300 away from the rotating axis of the knob 200, so that the water flowing out from the drain outlet 236 will flow through the guide gap 400 to the outer peripheral wall of the first water guide rib 300.

[0067] With this configuration, water entering through the inlet channel 237 will be discharged through the outlet 236, thus preventing water from accumulating in the inlet channel 237 and causing water to come into contact with the circuit inside the display module 240, resulting in a short circuit and damage to the circuit inside the display module 240. Furthermore, when the outlet 236 is located above the first water guide rib 300, the water flowing out of the outlet 236 will flow through the guide gap 400 to the outer peripheral wall of the first water guide rib 300, thus preventing the water flowing out of the outlet from flowing directly into the mounting hole 110.

[0068] Specifically, please refer to the following: Figures 5 to 6 The rotating assembly 230 includes a rotating ring 231 and an annular drive member 232. The rotating ring 231 has an annular mounting protrusion 231a and an annular guide portion 231b on its surface facing away from the mounting member 100. The annular drive member 232 is sleeved on the outer peripheral wall of the annular mounting protrusion 231a. The display portion 241 is located inside the annular drive member 232. The protrusion of the annular mounting protrusion 231a, the inner wall of the annular drive member 232, and the outer peripheral wall of the display portion 241 form a water inlet channel 237. The annular guide portion 231b is located inside the annular mounting protrusion 231a. The distance from the protrusion of the annular guide portion 231b to the mounting member 100 is greater than the distance from the annular mounting protrusion 231a to the mounting member 100.

[0069] With this configuration, after water enters the water inlet channel 237, it will first be affected by the convex top of the annular mounting protrusion 231a, thereby reducing the flow rate of the water when it is discharged from the water inlet channel 237. Subsequently, the water will contact the outer peripheral wall of the annular guide part 231b and enter the drain outlet 236 under the guidance of the annular guide part 231b. This avoids the water from contacting the circuit inside the display module 240, which could cause a short circuit and damage to the circuit inside the display module 240.

[0070] The rotating ring 231 can be used to support rotating components such as magnetic rings. The rotating ring 231 can be made of various materials, including metal and plastic; no specific limitation is made here. Preferably, the rotating ring 231 is made of plastic, which reduces the cost of the rotating assembly 230 and minimizes the impact of the rotating ring 231 on the transmission of power to components such as magnetic rings. The plastic can be ABS, PC, or a mixture of ABS and PC materials; no specific limitation is made here.

[0071] The annular drive component 232 is sleeved on the outer periphery of the rotating ring 231 and coaxially arranged with the rotating ring 231. This allows the user to rotate the rotating ring 231 by rotating the annular drive component 232. Simultaneously, the annular drive component 232 protects the rotating ring 231 and the components within the knob 200. The annular drive component 232 can be made of metal or a molded material; no specific limitation is made here. Preferably, the annular drive component 232 is made of an alloy material, which gives it high hardness and strong corrosion resistance, thereby enhancing its protective function for the rotating ring 231 and the components within the knob 200. The alloy material can be aluminum alloy or zinc alloy; no specific limitation is made here.

[0072] Please see Figure 5 One of the outer peripheral wall of the rotating ring 231 and the inner wall of the annular drive member 232 is provided with an installation channel 233 and a fastening groove 234. The fastening groove 234 is located on one side of the installation channel 233 in the circumferential direction of the rotating ring 231. The installation channel 233 extends along the rotation axis of the rotating assembly 230. The other of the outer peripheral wall of the rotating ring 231 and the inner wall of the annular drive member 232 is provided with a fastening part 235. It can be understood that when the installation channel 233 and the fastening groove 234 are provided on the outer peripheral wall of the rotating ring 231, the fastening part 235 is provided on the inner wall of the annular drive member 232; when the installation channel 233 and the fastening groove 234 are provided on the inner wall of the annular drive member 232, the fastening part 235 is provided on the outer peripheral wall of the rotating ring 231.

[0073] During the assembly of the rotating ring 231 and the annular drive member 232, the engaging part 235 can extend into the mounting channel 233 along the rotation axis, and the rotating ring 231 can rotate relative to the annular drive member 232, so that the engaging part 235 engages with the engaging groove 234. It should be noted that one end of the mounting channel 233 in the rotation axis needs to be through-hole so that the engaging part 235 can extend into the mounting channel 233 along the rotation axis.

[0074] For ease of understanding, the surface with the mounting channel 233 and the fastening groove 234 is designated as the first surface; the surface with the fastening part 235 is designated as the second surface. The fastening part 235 can be formed by a protrusion, which engages with the fastening groove 234. In this case, the mounting channel 233 extends through the second surface, making it recessed. Alternatively, the fastening part 235 can be hook-shaped, having a connecting part and a protrusion. In this case, the first surface also has a clearance channel, which is located on the same side of the mounting channel 233 in the circumferential direction of the rotating ring 231 as the fastening groove 234. The clearance channel communicates with both the mounting channel 233 and the fastening groove 234. When the rotating ring 231 rotates relative to the annular drive member 232, the connecting part rotates within the clearance channel, and the protrusion engages with the fastening groove 234. Further details are omitted here.

[0075] It should be noted that after the rotating assembly 230 is assembled, the fastening part 235 engages with the fastening groove 234, and the annular drive unit drives the rotating ring 231 to rotate through the engagement of the fastening part 235 and the fastening groove 234. There are many ways to prevent the fastening part 235 from exiting the fastening groove 234. For example, when the distance between the wall surface of the fastening groove 234 facing the second surface and the second surface is greater than the distance between the wall surface of the mounting channel 233 facing the second surface and the second surface, the fastening groove 234 communicates with the mounting channel 233, and the step formed between the wall surface of the mounting channel 233 facing the second surface and the wall surface of the fastening groove 234 facing the second surface abuts against the fastening part 235. Alternatively, by providing an abutment between the fastening groove 234 and the mounting channel 233, the abutment against the fastening part 235 can prevent the fastening part 235 from exiting. These methods will not be listed here.

[0076] Furthermore, please refer to the following: Figures 3 to 4 The display section 241 has an annular guide groove 241a recessed on its surface facing the mounting member 100, and the annular guide section 231b extends into the annular guide groove 241a. This arrangement allows the annular guide groove 241a and the annular guide section 231b to cooperate to form a labyrinth structure, thereby slowing down the water flow and providing better waterproofing. It should be noted that after passing through the annular guide section 231b and the annular guide groove 241a, the water flows towards the drain outlet 236, at which point the drain outlet 236 is at least partially located inside the annular guide section 231b.

[0077] Specifically, please refer to the following: Figures 3 to 4The annular guide portion 231b gradually decreases in distance from the pivot of the knob 200 in the direction away from the mounting member 100. This arrangement allows the annular guide portion 231b to better guide water from the inlet channel 237 into the annular guide groove 241a. Simultaneously, the annular guide portion 231b is inclined inwards in the direction away from the mounting member 100, which serves as a guide during the draft forming of the rotating ring 231, thus facilitating the forming of the rotating ring 231.

[0078] Please refer to the following: Figure 3 , Figure 4 as well as Figure 6 In some embodiments of this application, the rotating ring 231 is further provided with an annular drainage groove 231c on the surface facing away from the mounting member 100. The annular drainage groove 231c is located inside the annular guide portion 231b, and the first water guide rib 300 is located inside the annular drainage groove 231c. The drain outlet 236 includes an inner water leakage hole 236a, which is located at the bottom of the annular drainage groove 231c. With this configuration, when the inner drain hole 236a is located above the first water guide rib 300, the water entering through the water inlet channel 237 will pass through the annular guide section 231b, the annular guide groove 241a, and the annular drain groove 231c in sequence before being discharged from the inner drain hole 236a. It will then flow to the top of the first water guide rib 300 and finally flow to the left and / or right side of the first water guide rib 300 under the guidance of the first water guide rib 300. The drain groove can store some water, thereby preventing water from not being discharged from the inner drain hole 236a in time, which could cause water to flow into contact with the circuit inside the display module 240 and cause a short circuit damage to the circuit inside the display module 240. Meanwhile, the water in the annular drainage groove 231c will accumulate at the lower end of the annular drainage groove 231c under the influence of gravity. When the inner leakage hole 236a is located below the annular drainage groove 231c, the inner leakage hole 236a is located below the mounting hole 110. Therefore, after the water is discharged from the inner leakage hole 236a, it will not pass through the mounting hole 110, thereby preventing water from entering the mounting hole 110.

[0079] Furthermore, please refer to the following: Figures 3 to 4 The surface of the display unit 241 facing the mounting member 100 is also provided with an annular guide protrusion 241b. The annular guide protrusion 241b is located inside the annular guide groove 241a and extends into the annular drain groove 231c. With this configuration, the annular guide protrusion 241b can guide the water flowing out of the annular guide groove 241a into the annular drain groove 231c, thereby preventing water from flowing through the gap between the surface of the rotating ring 231 inside the annular drain groove 231c and the surface of the display unit 241 inside the annular guide groove 241a to come into contact with the circuit inside the display module 240, which would cause a short circuit and damage to the circuit inside the display module 240.

[0080] The annular guide protrusion 241b can be arranged radially spaced from the annular guide groove 241a in the rotating assembly 230, or it can be arranged close to the annular guide groove 241a; no specific limitation is made here. Preferably, the annular guide protrusion 241b is arranged close to the annular guide groove 241a, that is, the wall surface of the annular guide protrusion 241b near the annular guide groove 241a is coplanar with the groove wall of the annular guide groove 241a, which can better guide the water passing through the annular guide groove 241a into the annular drainage groove 231c.

[0081] Please see Figure 6 In some embodiments of this application, the bottom of the annular drainage groove 231c is provided with a plurality of first connecting ribs 231d. The plurality of first connecting ribs 231d are arranged at intervals along the circumference of the knob assembly 1000. The two ends of the first connecting ribs 231d in the radial direction of the knob assembly 1000 are respectively connected to the two opposite groove walls of the annular drainage groove 231c. By setting the first connecting ribs 231d, the strength of the rotating ring 231 at the annular drainage groove 231c can be enhanced, thereby extending the service life of the rotating ring 231.

[0082] Please see Figure 6 In some embodiments of this application, the surface of the rotating ring 231 facing away from the mounting member 100 is further provided with a plurality of second connecting ribs 231e. The plurality of second connecting ribs are arranged at intervals along the circumference of the knob assembly 1000, and the two ends of the second connecting ribs 231e in the radial direction of the knob assembly 1000 are respectively connected to the annular guide portion 231b and the annular mounting protrusion 231a. In this configuration, by providing the second connecting ribs 231e, the strength of the rotating ring 231 between the annular mounting protrusion 231a and the annular guide portion 231b can be enhanced, thereby extending the service life of the rotating ring 231.

[0083] Considering that water entering from the inlet channel 237 will flow circumferentially along the annular guide portion 231b under the influence of gravity, water will accumulate between the annular mounting protrusion 231a and the annular guide groove 241a. Therefore, please refer to... Figure 6 The drain outlet 236 also includes an outer drainage hole 236b, which is located between the annular mounting protrusion 231a and the annular guide section 231b. With this configuration, when the outer drainage hole 236b rotates to the lower part of the mounting hole 110, water accumulated between the annular mounting protrusion 231a and the annular guide groove 241a will flow out through the outer drainage hole 236b. Simultaneously, when water enters the water inlet channel 237 and the outer drainage hole 236b is located above the first guide rib 300, the water, guided by the annular guide section 231b, is discharged from the outer drainage hole 236b to the upper part of the first guide rib 300, and then flows to the left and / or right side of the first guide rib 300 under the guidance of the first guide rib 300.

[0084] Please see Figure 6 In some embodiments of this application, there are multiple drain outlets 236, which are arranged at intervals along the circumference of the knob assembly 1000. This arrangement allows for faster drainage of water from the rotating assembly 230, thus preventing water accumulation within the rotating assembly 230 and its potential impact on the circuitry of the display module 240.
