Embodiment Construction

[0030] The following will be combined with the appended in the embodiment of the application Figure 1 to Figure 8 , clearly and completely describe the technical solutions in the embodiments of the present application. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0031] The embodiment of the present application provides a noise reduction device 100, which can block the transmission of the vibration generated by the pump body 200 such as a vacuum pump during the working process, thereby reducing the vibration noise generated by the pump body 200 and realizing the smoothness of the pump body 200. noise reduction. Please refer to Figure 1 to Figure 4 , figure 1 A schematic structural diagram of the noise reduction device...

Abstract

The invention provides a noise reduction device and a refrigerator. A containing space used for containing a pump body is formed in the inner side of a first shell of the noise reduction device. The second shell is arranged on the outer side of the first shell in a sleeving mode, at least part of the second shell and at least part of the first shell are integrally formed and connected, a sealed space is formed between the second shell and the first shell, and the sealed space is used for blocking transmission of vibration generated by the pump body. On the basis, according to the noise reduction device, noise generated by vibration of the pump body is not prone to being transmitted to mounting parts such as the refrigerator from the second shell, the noise reduction device can greatly reduce the noise generated by vibration of the pump body, and the noise reduction device has the excellent noise reduction performance.

Description

technical field [0001] The present application relates to the field of noise reduction of refrigerators, in particular to a noise reduction device and a refrigerator. Background technique [0002] Refrigerators often need to use vacuum pumps to realize gas compression and air pressure control when realizing refrigeration and fresh-keeping functions. When the vacuum pump is working, it will generate a lot of noise due to eccentric vibration. [0003] The refrigerator noise reduction scheme in the related art is often fixed on the refrigerator cabinet after filling the noise reduction material around the vacuum pump. However, the noise reduction effect of this solution is not good, and the noise generated by the vacuum pump is still relatively large. Contents of the invention [0004] The application provides a noise reduction device and a refrigerator, the noise reduction device can effectively reduce the noise generated by the vibration of the vacuum pump, [0005] In a...
