Together with the common action of washing powder and water, the clothes are washed clean. Because of its reliable basic structure, delicate and compact production, and water saving, it is widely welcomed by people. During the use of the drum washing machine, in order to avoid water leakage at the joint between the lid and the body, a sealing ring is usually provided on the side of the lid to improve the sealing performance of the contact position.

[0003] In view of the above related technologies, the inventor found that: the existing sealing ring for the lid of a drum washing machine has a simple structure, is prone to falling off during use, and there are easily gaps at the contact position, affecting the sealing effect. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a sealing ring for the lid of a drum washing machine to solve the problems existing in the above background art.

[0005] To achieve the above object, the technical solution of the utility model is as follows:

[0006] A sealing ring for the lid of a drum washing machine includes a sealing ring main body. An installation ring is provided at the top end of the sealing ring main body. A cavity is opened at the top end of the sealing ring main body. The side surface of the sealing ring main body is an arc-shaped structure. The sealing ring main body is made of elastic rubber material. A groove is opened at the bottom end of the sealing ring main body.

[0007] Implementing the above technical solution, the installation ring and the side surface of the sealing ring main body form an annular cavity. When installing, the cavity is sleeved on the lid, so that an air bag is formed between the cavity and the lid. During use, the air in the cavity can play a role in buffering and shock absorption. At the same time, under the action of air pressure, the surface of the sealing ring main body fits more closely on the barrel wall of the washing machine, better playing a sealing role, which is beneficial to improving the sealing effect of the sealing ring. At the same time, when closing the lid, the sealing ring main body plays a role in shock absorption and buffering to avoid damage.

[0008] As a preferred solution of the present application, the sealing ring main body is processed and formed by an injection molding method, and the sealing ring main body is an integral structure.

[0009] As a preferred solution of the present application, an inner ring protrusion is fixedly connected to the inner wall of the side surface of the installation ring.

[0010] As a preferred embodiment of the present application, the side surface of the mounting ring is provided with anti-slip protrusions, and the top of the anti-slip protrusions forms an oblique angle of 30 degrees with the horizontal plane.

[0011] As a preferred embodiment of the present application, the surface of the sealing ring body is subjected to frosted treatment.

[0012] Technical effects and advantages of the present utility model:

[0013] 1. The present utility model forms an annular cavity through the side surfaces of the mounting ring and the sealing ring body. During installation, the cavity is sleeved on the barrel cover, so that an air bag is formed between the cavity and the barrel cover. During use, the air in the cavity can play a role in buffering and shock absorption. At the same time, under the action of air pressure, the surface of the sealing ring body fits more closely on the inner wall of the washing machine barrel, better playing a sealing role, which is beneficial to improving the sealing effect of the sealing ring. At the same time, when closing the barrel cover, the sealing ring body plays a role in shock absorption and buffering to avoid damage. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will further describe the present application in detail Figures 1-3 with reference to the accompanying drawings.

[0020] The embodiment of the present application discloses a sealing ring for the barrel cover of a drum washing machine. Refer to Figures 1 to 3, the present utility model provides a barrel cover sealing ring for a drum washing machine, including a sealing ring main body 1. An installation ring 2 is provided at the top end of the sealing ring main body 1. A cavity 6 is opened at the top end of the sealing ring main body 1. The side surface of the sealing ring main body 1 is an arc structure. The sealing ring main body 1 is made of elastic rubber material. A groove 5 is opened at the bottom end of the sealing ring main body 1. The installation ring 2 and the side surface of the sealing ring main body 1 form an annular cavity 6. When installed, the cavity 6 is sleeved on the barrel cover, so that an air bag is formed between the cavity 6 and the barrel cover. When in use, the air in the cavity 6 can play a role in buffering and shock absorption. At the same time, under the action of air pressure, the surface of the sealing ring main body 1 fits more closely on the barrel wall of the washing machine, better playing a sealing role.

[0021] The sealing ring main body 1 is processed and formed by an injection molding method, and the sealing ring main body 1 is an integral structure.

[0022] An inner ring protrusion 4 is fixedly connected to the inner wall of the side surface of the installation ring 2. The inner ring protrusion 4 is on the inner wall of the installation ring 2, which is convenient for fitting on the side surface of the barrel cover, increasing the contact area and improving the sealing effect.

[0023] Anti-slip protrusions 3 are provided on the side surface of the installation ring 2. The top end of the anti-slip protrusions 3 forms an angle of thirty degrees with the horizontal plane. When the installation ring 2 is sleeved on the barrel cover, the anti-slip protrusions 3 increase the friction between the installation ring 2 and the barrel cover to prevent falling off. At the same time, the obliquely downward inner ring protrusion 4 is convenient for sleeving the installation ring 2 on the barrel cover.

[0024] The surface of the sealing ring main body 1 is treated by frosting to increase the friction between the sealing ring main body 1 and the barrel cover and the washing machine body to prevent falling off.

[0025] The working principle of a barrel cover sealing ring for a drum washing machine in this application: When installed, the side surface of the cavity 6 is sleeved on the barrel cover. At this time, the obliquely downward inner ring protrusion 4 is convenient for sleeving the installation ring 2 on the barrel cover, and the anti-slip protrusions 3 increase the friction between the installation ring 2 and the barrel cover, so that an air bag is formed between the cavity 6 and the barrel cover. When in use, the air in the cavity 6 can play a role in buffering and shock absorption. At the same time, under the action of air pressure, the surface of the sealing ring main body 1 fits more closely on the barrel wall of the washing machine, better playing a sealing role.

[0026] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
