Description

Technical Field

[0001] This utility model relates to the field of drum washing machine technology, and more specifically to a drum noise reduction device for a drum washing machine. Background Technology

[0002] The washing method is designed to mimic the principle of beating clothes with a stick. It uses the mechanical work of an electric motor to rotate the drum. The clothes are repeatedly lifted and dropped inside the drum, and then lifted and dropped again, making a repetitive motion. With the combined action of detergent and water, the clothes are cleaned. Drum washing machines are widely popular because of their reliable basic structure, exquisite and compact manufacturing, and water-saving properties. The drum is an important component of the drum washing machine. When using it, the clothes to be washed are placed inside the drum, and the drive unit drives the drum to rotate, thus washing the clothes.

[0003] Existing technology has shortcomings: When a drum washing machine rotates, it shakes, and the clothes and water collide inside the drum, which can easily generate noise and affect people in the vicinity. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a drum noise reduction device for a drum washing machine to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drum noise reduction device for a drum washing machine, comprising a drum body and a noise reduction mechanism, wherein the inner side wall of the noise reduction mechanism is fixedly connected to the side of the drum body by an adhesive, the noise reduction mechanism includes a buffer layer, and a wear-resistant layer is fixedly connected to the side of the buffer layer by an adhesive, wherein the inner side wall of the buffer layer is fixedly connected to the side of the drum body by an adhesive.

[0006] To achieve the above technical solution, the buffer layer is closely attached to the surface of the drum body, which provides good sound insulation and reduces noise diffusion into the air. At the same time, the wear-resistant layer is wrapped around the surface of the buffer layer, which protects the buffer layer, improves the sealing of the wear-resistant layer, and plays a sound insulation role. This reduces the transmission of sound waves through air bubbles inside the buffer layer, which helps to reduce the noise of the drum washing machine.

[0007] As a preferred embodiment of this application, the buffer layer is a nitrile rubber foam material layer, and the wear-resistant layer is an aluminum foil layer.

[0008] As a preferred embodiment of this application, the side of the buffer layer is provided with a joint groove, and the joint groove has a Z-shaped structure.

[0009] As a preferred embodiment of this application, the side of the buffer layer is provided with edge protrusions.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. This utility model uses an adhesive coated on one side of the buffer layer, which is then bonded to the surface of the drum body. The buffer layer, made of nitrile rubber foam, adheres tightly to the surface of the drum body, providing good sound insulation and reducing noise diffusion into the air. At the same time, a wear-resistant layer wraps around the surface of the buffer layer, protecting it and improving its sealing performance, thus providing sound insulation and reducing the transmission of sound waves through air bubbles within the buffer layer, which helps to reduce the noise of the drum washing machine.

[0012] 2. This utility model has joint grooves at both ends of the buffer layer. When the buffer layer is adhered to the surface of the roller body, the joints of the buffer layer are staggered by the two joint grooves, which improves the sealing performance of the buffer layer and helps to improve the noise reduction effect of the noise reduction mechanism.

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0019] This application discloses a noise reduction device for a drum washing machine. (Refer to...) Figures 1 to 3This utility model provides a noise reduction device for a drum washing machine, including a drum body 1 and a noise reduction mechanism 2. The inner side wall of the noise reduction mechanism 2 is fixedly connected to the side of the drum body 1 by an adhesive. The noise reduction mechanism 2 includes a buffer layer 201, and a wear-resistant layer 202 is fixedly connected to the side of the buffer layer 201 by an adhesive. The inner side wall of the buffer layer 201 is fixedly connected to the side of the drum body 1 by an adhesive. The buffer layer 201 is a nitrile rubber foam layer, and the wear-resistant layer 202 is an aluminum foil layer. The noise reduction mechanism 2 is formed by bonding the wear-resistant layer 202 and the buffer layer 201 together. The buffer layer 201 is made of nitrile rubber foam. During production and processing, one side of the buffer layer 201 is coated with adhesive and then bonded to the surface of the roller body 1. The buffer layer 201, made of nitrile rubber foam, has excellent waterproof, moisture-proof, cushioning and shock-absorbing, sound-absorbing, sound-insulating and flame-retardant properties. It adheres tightly to the surface of the roller body 1 and provides good sound insulation, reducing noise diffusion into the air. At the same time, the wear-resistant layer 202 wraps around the surface of the buffer layer 201, protecting the buffer layer 201, improving the sealing of the wear-resistant layer 202, and providing sound insulation, thus reducing the transmission of sound waves through air bubbles inside the buffer layer 201.

[0020] The buffer layer 201 has a joint groove 203 on its side. The joint groove 203 has a Z-shaped structure. The buffer layer 201 adhered to the surface of the roller body 1 is an integral structure. Both ends of the buffer layer 201 have joint grooves 203. When the buffer layer 201 is adhered to the surface of the roller body 1, the joint of the buffer layer 201 is staggered by the two joint grooves 203, which improves the sealing performance of the buffer layer 201.

[0021] The side of the buffer layer 201 is provided with edge protrusions 204, and the wear-resistant layer 202 on the surface of the buffer layer 201 is provided with edge protrusions 204 extending beyond the edge in three directions, so as to ensure that when the noise reduction mechanism 2 is adhered to the surface of the roller body 1, the wear-resistant layer 202 can completely cover the buffer layer 201 to protect the buffer layer 201.

[0022] The implementation principle of the noise reduction device for a drum washing machine according to an embodiment of this application is as follows: The noise reduction mechanism 2 is composed of a wear-resistant layer 202 and a buffer layer 201 bonded together with an adhesive. During production and processing, one side of the buffer layer 201 is coated with adhesive and bonded to the surface of the drum body 1. At the seam of the buffer layer 201, two seam grooves 203 engage to stagger the seams and adhere tightly to the surface of the drum body 1, thereby achieving a good sound insulation effect and reducing noise diffusion into the air. At the same time, the wear-resistant layer 202 completely wraps around the surface of the buffer layer 201, protecting the buffer layer 201, improving the sealing performance of the wear-resistant layer 202, and playing a sound insulation role, thereby reducing the transmission of sound waves through air bubbles inside the buffer layer 201.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
