Abstract

The invention discloses a refrigerator vacuum assembly, comprising: an upper sealing body and a lower sealing body, the upper sealing body and the lower sealing body can be fastened to define a sealed accommodation chamber; a vacuum pump is arranged in the accommodation chamber; The plate-shaped member is arranged between the vacuum pump and the side wall of the sealed box for sound insulation; the upper sealing body is equipped with a number of abutting pieces, and the abutting pieces abut against the plate-shaped sealing body when the upper sealing body and the lower sealing body are closed. On the top of the member, a stepped portion is arranged at the end where the abutting member contacts the plate-shaped member, the top surface of the stepped portion abuts against the top surface of the plate-shaped member, and the side of the stepped portion abuts against the side of the plate-shaped member; the lower sealing body is equipped with several ribs , the rib and the side wall are arranged at intervals to define the limiting groove of the plate-shaped member; the lower sealing body is configured with a number of guide grooves, and the guide grooves extend vertically to guide the plate-shaped member.

Description

technical field [0001] The invention belongs to the technical field of noise reduction of refrigeration equipment, and in particular relates to a sealing member for reducing the noise of a vacuum pump. Background technique [0002] The preservation of food in the refrigerator is closely related to temperature, humidity and gas environment. Among them, oxygen is an important factor that causes food spoilage and bacterial reproduction. Controlling the ratio of nitrogen and oxygen in the refrigerator by pumping oxygen in the compartment can significantly prolong the preservation time of food. [0003] Oxygen can be drawn from a specific space by a vacuum pump and discharged to the outside of the refrigerator. However, gas, as a sound-conducting medium, will transmit the noise inside the cabinet to the outer space of the refrigerator during the discharge process, forming noise interference. Contents of the invention [0004] The purpose of the present invention is to provid...
