Abstract

The invention discloses a silencer. The silencer comprises a hollow cavity defined by a first bottom surface, a second bottom surface and a side wall; the side wall is connected with the first bottomsurface and the second bottom surface; a gas inlet is formed in one end of the silencer, and a gas outlet is formed in the other opposite end of the silencer; the cavity is divided into a plurality ofchambers in the axial direction; the chambers include the first chamber adjacent to the first bottom surface, the second chamber adjacent to the second bottom surface and the middle chamber located between the first chamber and the second chamber; the gas inlet communicates with gas of the middle chamber; the middle chamber communicates with gas of the second chamber; the first chamber communicates with gas of the second chamber; and the gas outlet communicates with gas of the first chamber.

Description

technical field [0001] The invention belongs to the technical field of noise reduction of refrigeration equipment, and in particular relates to a muffler 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 provide a muf...
