Abstract
Description
Technical Field
[0001] This application relates to the technical field of sealing strips, and in particular to a noise-reducing sealing strip for a washing machine. Background Technology
[0002] Currently, in the dryer industry, clothing is generally made of fabrics, including cotton, polyester, wool, and other synthetic fibers. Sometimes, the washing materials damage the fabric fibers, causing fine fibers to separate from the fabric. During the drying process, the increased temperature and moisture loss, along with the mechanical force of the dryer's rotation and the friction between the fabric, cause these fine fibers to detach, resulting in lint. Traditional door seals often use solid, closed rings. During use, a spring-loaded clamp holds the seal in place within the machine's mounting groove. However, during operation, moisture can cause the spring-loaded clamp to oxidize and rust. Furthermore, the vibrations of the washing machine itself can cause the seal's surface to harden and oxidize, forming a smooth layer. This smooth surface can then rub against the machine body during operation, generating sharp noise. Utility Model Content
[0003] To address the aforementioned technical problems, this application provides a noise-reducing sealing strip for washing machines, which has the advantage of reducing the occurrence of sharp vibration noise after the sealing ring surface hardens due to oxidation caused by rust and vibration, forming a smooth surface.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows:
[0005] A noise-reducing sealing strip for a washing machine includes a body, the body comprising a connecting portion and a sealing portion;
[0006] The connecting part includes an upper connecting leg and a lower connecting leg connected to each other at one end. The upper connecting leg is provided with an upper felt at the end away from the lower connecting leg, and the lower connecting leg is provided with a lower felt at the end away from the upper connecting leg. The lower connecting leg is provided with a sealing protrusion that protrudes upward towards the upper connecting leg at the end away from the sealing part.
[0007] To achieve the above technical solution, the upper connecting foot is fixed to the fixing groove of the inner drum of the washing machine by a spring clamp. At this time, the lower felt is in contact with the positioning groove, and the upper connecting foot is pressed against the lower connecting foot by the positioning wall above the positioning groove of the inner drum, thus completing the installation and positioning of the connection part. At the same time, the upper connecting foot is pressed against the sealing protrusion, so that a sealing cavity is formed between the upper and lower connecting feet. The spring clamp is placed in the sealing cavity, thereby reducing or even preventing moisture from entering and reducing the oxidation of the spring clamp. This prevents the sealing ring surface from hardening due to rust and vibration, forming a smooth surface layer, which would cause sharp vibration noise. The upper and lower felt can prevent the rubber upper and lower connecting feet from directly contacting the inner drum, thereby further reducing vibration and noise.
[0008] As a preferred embodiment of this application, the upper connecting foot is provided with an arc-shaped surrounding portion that protrudes downward in the direction of the connecting foot at the end away from the sealing portion.
[0009] By implementing the above technical solution, after the upper connecting foot is restricted by the outside, the arc-shaped surrounding part can tightly hug the sealing protrusion, thereby ensuring the sealing effect and further reducing noise.
[0010] As a preferred embodiment of this application, the lower felt protrudes beyond the lower connecting foot.
[0011] By implementing the above technical solution, the lower felt can bend upwards to wrap around the upper connecting foot, thereby making the upper and lower connecting feet completely wrapped by the upper and lower felt, which further reduces noise and other issues.
[0012] As a preferred embodiment of this application, the sealing part is provided with a first sealing lip and a second sealing lip in the direction away from the connecting part. When the washing machine door is closed, the first sealing lip presses against the second sealing lip, which in turn forces the free end of the second sealing lip to press against the sealing part.
[0013] To achieve the above technical solution, when the washing machine door is closed, the first sealing lip presses against the second sealing lip, forcing the free end of the second sealing lip to press against the sealing part, thereby forming a double-layer sealing cavity between the first sealing lip, the second sealing lip, and the sealing part, thus further achieving the effect of sound insulation and noise reduction.
[0014] In summary, this application includes at least one of the following beneficial technical effects:
[0015] 1. The upper connecting foot is fixed to the fixing groove of the inner drum of the washing machine by the spring clamp. At this time, the lower felt is in contact with the positioning groove, and the upper connecting foot is pressed against the lower connecting foot by the positioning wall above the positioning groove of the inner drum, thus completing the installation and positioning of the connection part. At the same time, the upper connecting foot is pressed against the sealing protrusion, so that a sealing cavity is formed between the upper and lower connecting feet. The spring clamp is placed in the sealing cavity, thereby reducing or even preventing moisture from entering and reducing the oxidation of the spring clamp. This prevents the sealing ring surface from hardening due to rust and vibration, forming a smooth surface and causing sharp noise from vibration. The upper and lower felt can prevent the rubber upper and lower connecting feet from directly contacting the inner drum, thereby further reducing vibration and noise. Attached Figure Description

[0021] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0022] This application discloses a noise-reducing sealing strip for a washing machine. (Refer to...) Figure 1-3 The noise-reducing sealing strip for the washing machine includes a body 1, which includes a connecting part 11 and a sealing part 12. The sealing strip is fixed in the positioning groove of the inner drum by the connecting part 11, and the sealing part 12 connects the door to the machine body.
[0023] The connecting part 11 includes an upper connecting foot 111 and a lower connecting foot 112 connected to each other at one end. An upper felt 113 is provided at the end of the upper connecting foot 111 away from the lower connecting foot 112, and a lower felt 114 is provided at the end of the lower connecting foot 112 away from the upper connecting foot 111. A sealing protrusion 115 protruding upward towards the upper connecting foot 111 is provided at the end of the lower connecting foot 112 away from the sealing part 12. The upper connecting foot 111 is fixed to the fixing groove of the inner drum of the washing machine by the spring clamp. At this time, the lower felt 114 is in contact with the positioning groove, and the upper connecting foot 111 is pressed against the lower connecting foot 112 by the positioning wall above the positioning groove of the inner drum, thus completing the installation and positioning of the connecting part 11. At the same time, the upper connecting foot 111 is pressed against the sealing protrusion 115, so that a sealing cavity is formed between the upper connecting foot 111 and the lower connecting foot 112. The spring clamp is placed in the sealing cavity, thereby reducing or even preventing moisture from entering and reducing the oxidation of the spring clamp. This prevents the sealing ring surface from hardening due to rust and vibration, forming a smooth surface layer, which would cause sharp vibration noise. The upper felt 113 and the lower felt 114 can prevent the rubber upper connecting foot 111 and the lower connecting foot 112 from directly contacting the inner drum, thereby further reducing vibration and noise.
[0024] An arc-shaped surrounding portion 116 protruding downwards from the sealing portion 12 is provided at the end of the upper connecting foot 111 away from the sealing portion 12. Thus, when the upper connecting foot 111 is restricted by the outside, the arc-shaped surrounding portion 116 can hug the sealing protrusion 115, thereby ensuring the sealing effect and further reducing noise.
[0025] The lower felt 114 protrudes from the lower connecting foot 112, allowing the lower felt 114 to bend upwards and wrap around the upper connecting foot 111. This results in the upper connecting foot 111 and the lower connecting foot 112 being completely wrapped around the periphery by the upper felt 113 and the lower felt 114, thereby further reducing noise and other issues.
[0026] The sealing part 12 is provided with a first sealing lip 121 and a second sealing lip 122 in the direction away from the connecting part 11. When the washing machine door is closed, the first sealing lip 121 presses against the second sealing lip 122, forcing the free end of the second sealing lip 122 to press against the sealing part 12, thereby forming a double-layer sealing cavity between the first sealing lip 121, the second sealing lip 122 and the sealing part 12, thereby further achieving the effect of sound insulation and noise reduction.
[0027] The implementation principle of a noise-reducing sealing strip for a washing machine according to an embodiment of this application is as follows: the upper connecting foot 111 is fixed to the fixing groove of the inner drum of the washing machine by a spring clamp. At this time, the lower felt 114 is in contact with the positioning groove, and the upper connecting foot 111 is pressed against the lower connecting foot 112 by the positioning wall above the positioning groove of the inner drum, thereby completing the installation and positioning of the connecting part 11. At the same time, the upper connecting foot 111 is pressed against the sealing protrusion 115, so that a sealing cavity is formed between the upper connecting foot 111 and the lower connecting foot 112. At this time, the spring clamp is set in the sealing cavity, thereby reducing or even preventing moisture from entering and reducing the oxidation of the spring clamp. This prevents the rust and vibration from causing the sealing ring surface to oxidize and harden, forming a smooth surface layer, resulting in sharp vibration noise. The upper felt 113 and the lower felt 114 can prevent the rubber upper connecting foot 111 and the lower connecting foot 112 from directly contacting the inner drum, thereby further achieving the effect of shock absorption and noise reduction.
[0028] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
