Description

Technical Field

[0001] This utility model relates to the field of washing machine accessories technology, and in particular to a highly wear-resistant washing machine door ring. Background Technology

[0002] Among the many components of a washing machine, the washing machine door seal plays a crucial role. As a key component connecting the machine body and the door panel, it mainly undertakes the function of sealing. When the washing machine is running, the door seal can effectively prevent water from seeping out from the gap between the machine body and the door panel, avoiding water flowing to the ground and causing safety hazards. At the same time, it also ensures a stable washing environment inside the washing machine and ensures that the washing process proceeds smoothly.

[0003] As one of the important components of a washing machine, the washing machine door seal is frequently affected by factors such as friction, detergent corrosion, and humidity changes during daily use. It is prone to wear, deformation, and aging, which not only affects the appearance of the washing machine but may also lead to a decrease in sealing performance, causing malfunctions such as water leakage, reducing the lifespan of the washing machine and the user experience.

[0004] Therefore, this utility model proposes a highly wear-resistant washing machine door ring. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and propose a highly wear-resistant washing machine door ring.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a highly wear-resistant washing machine door ring, comprising:

[0007] A sealing ring assembly, which consists of an outer rubber ring and an inner rubber ring, wherein the inner rubber ring is snapped onto the inside of the outer rubber ring;

[0008] An outer rubber ring is provided with a first compression pad on the side of the outer rubber ring near the inner rubber ring. A first inner groove is provided on the outer rubber ring on the side of the first compression pad. A first reinforcing rib and a first elastic rib are provided in the first compression pad.

[0009] An inner rubber ring is provided with a second compression pad on the side of the inner rubber ring near the outer rubber ring. A second inner groove is provided on the side of the inner rubber ring located on the second compression pad. A second reinforcing rib and a second elastic rib are provided inside the second compression pad.

[0010] In a preferred embodiment, the first elastic ribs are arranged in a ring, and the included angle between two adjacent first reinforcing ribs is equal.

[0011] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the first elastic rib, the elasticity of the outer rubber ring is increased, and the deformation of the outer rubber ring after long-term use is avoided, which would lead to a decrease in the sealing effect.

[0012] In a preferred embodiment, the diameter of the first inner groove is adapted to the diameter of the second compression pad.

[0013] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the first inner groove, the second compression pad is limited, preventing the outer rubber ring and the inner rubber ring from separating during use.

[0014] In a preferred embodiment, the second elastic ribs are arranged in a ring, and the included angle between two adjacent second elastic ribs is equal.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the second elastic rib, it provides auxiliary support for the inner rubber ring, and avoids deformation of the inner rubber ring after being squeezed during use, which would reduce the sealing effect of the inner rubber ring.

[0016] In a preferred embodiment, the diameter of the second inner groove is adapted to the diameter of the first compression pad.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the first compression pad is limited by the second inner groove, so that the outer rubber ring and the inner rubber ring form a mutually interlocking limiting state, thereby preventing the outer rubber ring and the inner rubber ring from separating during use.

[0018] In a preferred embodiment, an outer friction pad is provided on the side of the outer rubber ring away from the inner rubber ring.

[0019] The beneficial effects of adopting the above-mentioned further solution are: under the action of the outer friction pad, it is used to connect the outer rubber ring and the machine body, and the outer friction pad is a deformable structure, so the outer friction pad will deform with the extrusion force during use, thereby improving the sealing effect.

[0020] In a preferred embodiment, an inner friction pad is provided on the side of the inner rubber ring away from the outer rubber ring.

[0021] The beneficial effects of adopting the above-mentioned further solution are: under the action of the inner friction pad, the inner rubber ring is connected to the housing, and the friction between the inner rubber ring and the housing is increased by the inner friction pad, thus preventing the inner rubber ring from rotating on the housing during use.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] 1. In this utility model, the outer rubber ring and the inner rubber ring are connected to each other by a first compression pad, a first inner groove, a second compression pad, and a second inner groove. The advantage of using a double layer is that, in actual use, the inner rubber ring is mainly used to prevent water leakage, while the outer rubber ring plays an auxiliary sealing and protection role for the inner rubber ring. The double-layer sealing structure can effectively improve the sealing reliability of the door ring and reduce water leakage problems caused by poor sealing.

[0024] 2. In this utility model, the local strength of the arch is enhanced by the action of the first reinforcing rib and the second reinforcing rib, and the friction force is dispersed to reduce the phenomenon of concentrated wear. Furthermore, the elasticity of the outer rubber ring and the inner rubber ring is improved by the action of the first elastic rib and the second elastic rib, so as to avoid material fatigue after long-term use, loss of elasticity of the water-guiding outer rubber ring and the inner rubber ring, and thus reduce the stability of the sealing effect.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figure 1-3 As shown, this utility model provides a technical solution: a highly wear-resistant washing machine door ring, comprising:

[0032] The sealing ring assembly 1 consists of an outer rubber ring 2 and an inner rubber ring 3, with the inner rubber ring 3 snapped onto the inner side of the outer rubber ring 2.

[0033] The outer rubber ring 2 has a first compression pad 21 on the side of the outer rubber ring 2 close to the inner rubber ring 3. A first inner groove 22 is provided on the outer rubber ring 2 on the side of the first compression pad 21. A first reinforcing rib 23 and a first elastic rib 24 are provided inside the first compression pad 21.

[0034] The inner rubber ring 3 has a second compression pad 31 on the side of the inner rubber ring 3 closest to the outer rubber ring 2. The inner rubber ring 3 has a second inner groove 32 on one side of the second compression pad 31. The second compression pad 31 has a second reinforcing rib 33 and a second elastic rib 34. The diameter of the first inner groove 22 is matched with the diameter of the second compression pad 31, and the diameter of the second inner groove 32 is matched with the diameter of the first compression pad 21. The outer rubber ring 2 and the inner rubber ring 3 are connected by the first compression pad 21, the first inner groove 22, the second compression pad 31, and the second inner groove 32. The advantage of using a double layer is that in actual use, the inner rubber ring 3 is mainly used to prevent water leakage, while the outer rubber ring 2 plays an auxiliary sealing and protection role for the inner rubber ring 3. The double-layer sealing structure can effectively improve the sealing reliability of the door ring and reduce water leakage problems caused by poor sealing.

[0035] Furthermore, such as Figures 2-3 As shown: the first elastic rib 24 is distributed in a ring, and the included angle between two adjacent first reinforcing ribs 23 is equal. The second elastic rib 34 is distributed in a ring, and the included angle between two adjacent second elastic ribs 34 is equal. Under the action of the first reinforcing rib 23 and the second reinforcing rib 33, the local strength of the arch is enhanced, and the friction force can be dispersed to reduce the phenomenon of concentrated wear. Furthermore, under the action of the first elastic rib 24 and the second elastic rib 34, the elasticity of the outer rubber ring 2 and the inner rubber ring 3 is improved, avoiding material fatigue after long-term use, which would cause the outer rubber ring 2 and the inner rubber ring 3 to lose elasticity and reduce the stability of the sealing effect.

[0036] The above solutions still have a sealing problem between the outer rubber ring 2 and the machine body, such as... Figure 3 As shown: In this solution, an outer friction pad 25 is provided on the side of the outer rubber ring 2 away from the inner rubber ring 3. Under the action of the outer friction pad 25, it is used to connect the outer rubber ring 2 to the machine body. The outer friction pad 25 is a deformable structure, so the outer friction pad 25 will deform with the compression force during use, thereby improving the sealing effect.

[0037] The above solutions still have the problem of sealing the inner rubber ring 3 with the shell, such as... Figure 3As shown: In this solution, an inner friction pad 35 is provided on the side of the inner rubber ring 3 away from the outer rubber ring 2. Under the action of the inner friction pad 35, the inner rubber ring 3 is connected to the housing. The friction between the inner rubber ring 3 and the housing is increased by the inner friction pad 35, so as to prevent the inner rubber ring 3 from rotating on the housing during use.

[0038] Working principle:

[0039] like Figure 1-3 As shown, the sealing ring assembly 1 is first installed and fixed on the washing machine shell by fitting the inner friction pad 35. When the washing machine shell and the machine body are closed, the outer friction pad 25 is squeezed and deformed, filling the gap between the shell and the machine body. Furthermore, under the action of the outer rubber ring 2 and the inner rubber ring 3, as the shell and the machine body are closed, they deform and fit together, adapting and filling the gap between the shell and the machine body to achieve a sealing effect.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
