[0039] In related technologies, with the diversification of clothing processing machines on the market, the quality of laundry detergents and washing machines varies greatly. During washing, excessive foam can easily overflow from the drum, severely impacting the user experience.

[0040] This application provides a water inlet component and a washing device to solve the problem of foam overflow in existing washing devices. The following will be described in conjunction with the accompanying drawings. Figure 1-6 Please provide an explanation.

[0041] The water inlet assembly provided in this application embodiment is referenced from... Figure 1 , Figure 2 and Figure 3 As shown, the device includes a water inlet box 100, a water inlet pipe 200, a baffle 300, and a reset member 400. One end of the water inlet pipe 200 is connected to the water inlet box 100, and the other end is provided with a water inlet 210 for connecting to the washing drum. The baffle 300 is slidably disposed on the water inlet pipe 200 and is adapted to move under the action of water flow in the water inlet pipe 200 to move from a first position to a second position. The reset member 400 is connected to the baffle 300 and is used to drive the baffle 300 to reset to the first position when the water inlet pipe 200 stops supplying water. In the first position, the baffle 300 blocks the water inlet 210, and in the second position, the baffle 300 opens the water inlet 210.

[0042] In this embodiment, the water inlet box 100 can be connected to an external water supply system and guide water to the water inlet pipe 200 through an internal pipe. The water inlet pipe 200 is a connecting component that connects the water inlet box 100 and the washing drum, used to deliver water into the washing drum for washing. The baffle 300 is slidably disposed on the water inlet pipe 200 and is used to control the opening and closing of the water inlet 210. The reset member 400 can be made of an elastic material, such as a spring, to provide a reverse driving force, ensuring that the baffle 300 can accurately and quickly reset to the state of blocking the water inlet 210 when water intake stops.

[0043] When water needs to be added to the washing drum, the water pressure pushes the baffle 300 from the first position to the second position, opening the water inlet 210 and allowing water to flow into the washing drum through it. After water intake is complete, the reset member 400 can drive the baffle 300 back to the first position (blocking the water inlet 210), cutting off the water intake channel. This effectively prevents foam generated during washing from entering the water inlet pipe 200 through the water inlet 210, avoiding the inconvenience caused by foam overflow. By physically isolating the system, the possibility of foam backflow is blocked, reducing cleaning and maintenance workload, creating a cleaner and tidier laundry environment for users, and improving the overall laundry experience.

[0044] In one alternative implementation, refer to Figure 2 and Figure 5As shown, a limiting plate 220 is provided inside the water inlet pipe 200, and a guide post 221 is provided on the limiting plate 220. The baffle 300 is slidably disposed on the guide post 221; in the first position, the baffle 300 abuts against the limiting plate 220.

[0045] In this embodiment, the limiting plate 220 can be a component fixed to the inner wall of the water inlet pipe 200, and its position is set at the ideal stopping point when the baffle 300 is in the position of completely blocking the water inlet 210 (first position). One or more guide posts 221 are provided on the limiting plate 220, and these guide posts 221 can be protrusions extending from the limiting plate 220. At the same time, corresponding guide parts, such as guide holes, sleeves, grooves, or slots, can also be provided on the baffle 300 to match the guide posts 221.

[0046] When the water inlet pipe 200 stops supplying water, the reset element 400 (such as a spring) drives the baffle 300 to move to the first position. When the baffle 300 slides to the position where the water inlet 210 is completely blocked, it will abut against the limiting plate 220, ensuring that the baffle 300 reliably stays in the blocked position and will not excessively rebound due to the continuous force of the reset element 400, thereby ensuring complete and stable blocking of the water inlet 210. The guide post 221 reduces the shaking or offset of the baffle 300 during the sliding process, making its movement more stable and reliable, and integrates the limiting and guiding functions into the water inlet pipe 200, making the overall structure more compact and integrated.

[0047] In one optional implementation, combined with Figure 3 and Figure 5 As shown, the limiting plate 220 is provided with multiple reinforcing ribs 222, and water passage holes 223 are formed between adjacent reinforcing ribs 222; the water inlet 210 is opened on the side of the water inlet pipe 200, and in the second position, the water inlet 210 is connected to the water passage hole 223.

[0048] In this embodiment, the reinforcing rib 222 can be a strip structure, and a channel, namely a water passage hole 223, is naturally formed between adjacent reinforcing ribs 222. These water passage holes 223 are the path for water flow through the limiting plate 220 area. When water enters the water inlet pipe 200, the water flow contacts the baffle 300 through the water passage hole 223 and pushes the baffle 300 to move. As the baffle 300 moves, the water inlet 210 on the side wall of the water inlet pipe 200, which was originally blocked by the baffle 300, is opened.

[0049] In one alternative implementation, refer to Figure 2 and Figure 4 As shown, the reset member 400 is an elastic member such as a spring. The reset member 400 is sleeved on the guide post 221 and located on the side of the baffle 300 away from the limiting plate 220. One end of the elastic member abuts against the guide post 221 and the other end abuts against the baffle 300.

[0050] In this embodiment, the guide post 221 can guide the sliding direction of the baffle 300 and also be used to install the elastic element. Using the elastic element as the reset power source results in a relatively simple structure, reduces complex mechanisms and additional connection points, and improves reliability. The elasticity of the elastic element makes the reset process smooth and controllable. Furthermore, the magnitude of the reset force can be precisely adjusted by selecting elastic elements with different stiffness or preload, ensuring reliable reset under various working conditions.

[0051] In one alternative implementation, refer to Figure 2 As shown, the baffle 300 has a mounting groove 310 along the circumferential direction on the side facing the limiting plate 220, and a sealing ring 320 is installed in the mounting groove 310; in the first position, the sealing ring 320 abuts against the limiting plate 220.

[0052] In this embodiment, compared to relying solely on hard contact between the baffle 300 and the limiting plate 220, the elastic sealing ring 320 can better fill the tiny gaps between them, significantly improving the sealing effect and effectively preventing water or foam from leaking out. As a buffer, the sealing ring 320 reduces direct hard friction between the baffle 300 and the limiting plate 220, extending their service life. Furthermore, the sealing ring 320 has a certain degree of elasticity, allowing it to adapt to minor processing errors or deformations that may exist in the baffle 300 or the limiting plate 220, ensuring reliable sealing. Better sealing performance directly reduces the risk of foam leakage, improving the user experience.

[0053] In one alternative implementation, refer to Figure 4 and Figure 5 As shown, the end of the water inlet pipe 200 is provided with a plurality of spaced-apart partitions 201 along the circumferential direction, and a water inlet 210 is formed between two adjacent partitions 201. The plurality of water inlets 210 are arranged around the circumferential direction of the water inlet pipe 200.

[0054] In this embodiment, the end of the water inlet pipe 200 is provided with multiple spaced partitions 201 arranged circumferentially, as if the pipe opening is divided into several segments. Each pair of adjacent partitions 201 forms a water inlet 210, so that multiple water inlets 210 are distributed around the pipe opening, providing multiple channels for water to enter the washing drum, improving water intake efficiency, and introducing water into the washing drum more evenly.

[0055] In one alternative implementation, refer to Figure 4 and Figure 6 As shown, the baffle 300 has a defoaming section 330 on the side facing the washing drum.

[0056] In this embodiment, a structure specifically designed to handle foam is added to the baffle 300, aiming to further reduce the risk of foam entering the water inlet pipe 200 through the water inlet 210 and overflowing. The side of the baffle 300 facing the washing drum refers to the side of the baffle 300 closest to the inside of the washing drum, which faces the water and foam inside the washing drum.

[0057] Optionally, the defoaming section 330 may have a structure including, but not limited to, a textured surface: disrupting foam stability through surface microstructure. Small turbulence-inducing plates / protrusions can increase turbulence as water flows through, accelerating foam breakage. A hydrophilic coating promotes the fusion of foam and water, accelerating defoaming. The defoaming section 330 can act on the foam it contacts, causing it to break, coalesce, or dissolve, reducing foam volume and stability, thereby further reducing the risk of foam spillage.

[0058] By adding a defoaming section 330 to the baffle 300, a mechanism for actively handling foam is provided. The defoaming section 330 can directly act on the foam itself, reducing the amount of foam entering the water inlet pipe 200 at the source. Even if the amount of foam in the washing drum is very large, or if the water flow may carry a small amount of foam towards the water inlet 210, the defoaming section 330 can still play a certain role in interception and elimination, adding an extra layer of protection to the sealing function of the baffle 300 and making the reliability of foam overflow prevention higher.

[0059] In one alternative implementation, refer to Figure 6 As shown, the defoaming part 330 is a defoaming protrusion, and the defoaming part 330 is integrally formed with the baffle 300.

[0060] On the side of the baffle 300 facing the washing drum, instead of a smooth surface, one or more defoaming protrusions are provided. These protrusions can be regular (e.g., cylindrical, conical, hemispherical) or irregular. Optionally, the baffle 300 with protrusions can be directly molded in a mold through injection molding, making the protrusions and the baffle 300 an inseparable whole.

[0061] When water or foam-containing liquid flows over these protrusions, the protrusions disrupt the smoothness of the flow, creating tiny eddies and turbulence. These eddies and turbulence impact the foam film, increasing the frequency of foam bursting. Optionally, sharp points can be provided at the top of the defoaming protrusions to directly puncture passing foam. This physical method effectively breaks larger bubbles into smaller ones, or causes them to burst directly, thereby reducing the overall volume and stability of the foam and minimizing the risk of foam spillage.

[0062] In one alternative implementation, refer to Figure 4 and Figure 6As shown, the defoaming section 330 has a through hole 331, which connects the water inlet pipe 200 and the washing drum.

[0063] In this embodiment, the defoaming protrusion may be provided with tiny through holes 331, which can ensure that the pressure inside the washing drum is connected to the outside, avoid high or low pressure inside the washing drum, reduce the risk of deformation and breakage of the washing drum, and improve the safety performance of the washing equipment.

[0064] In one alternative implementation, refer to Figure 4 and Figure 6 As shown, there are multiple defoaming sections 330, and the multiple defoaming sections 330 are arranged at intervals along the circumference of the baffle 300.

[0065] In this embodiment, by setting multiple defoaming sections 330, the defoaming effect is more comprehensive and uniform, with a larger coverage area, which can better adapt to the complex foam distribution inside the washing drum. Because the defoaming effect is more comprehensive, it can more effectively reduce the foam concentration and stability in the area near the water inlet 210 inside the washing drum, thereby significantly reducing the risk of foam entering the water inlet pipe 200 through the water inlet 210 and causing overflow. Even when the amount of foam generated is large, this multi-point protection can provide more reliable protection.

[0066] The water inlet assembly provided in this application includes a water inlet box 100, a water inlet pipe 200, a baffle 300, and a reset member 400. One end of the water inlet pipe 200 is connected to the water inlet box 100, and the other end is provided with a water inlet 210 for connecting to the washing drum. The baffle 300 is slidably disposed on the water inlet pipe 200 and is adapted to move under the action of water flow in the water inlet pipe 200 to move from a first position to a second position. The reset member 400 is connected to the baffle 300 and is used to drive the baffle 300 to reset to the first position when the water inlet pipe 200 stops supplying water. In the first position, the baffle 300 blocks the water inlet 210, and in the second position, the baffle 300 opens the water inlet 210. When water needs to enter during the washing process, the water pressure overcomes the restoring force of the reset member 400, pushing the baffle 300 from the first position to the second position to open the water inlet 210 for water to enter; after the water enters, the reset member 400 can drive the baffle 300 back to the first position, blocking the water inlet 210, preventing the foam generated during the washing process from entering the water inlet pipe 200 through the water inlet 210, and further preventing the foam from overflowing out of the washing machine along the water inlet pipe 200.

[0067] Secondly, embodiments of this application also provide a washing device, which includes a washing drum and a water inlet assembly as described in the above embodiments.

[0068] It is understood that the washing equipment in this embodiment may include, but is not limited to, household appliances such as drum washing machines, drum washer-dryers, washer-dryer sets, shoe washing machines, and dishwashers.

[0069] It is understood that since the water inlet component has the beneficial effects of the above embodiments, the washing equipment will have the corresponding beneficial effects of the above embodiments. The specific implementation method can be referred to the above embodiments, and this embodiment will not repeat the details.

[0070] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should all be covered within the protection scope of this application.
