Abstract

The invention discloses a silencer. The silencer comprises a hollow cavity formed by joint enclosing of a first bottom face, a second bottom face and a side wall, the side wall is connected with the first bottom face and the second bottom face, the first bottom face is provided with an air inlet, and the second bottom face is provided with an air outlet; and the air inlet communicates with the cavity in a guided mode through a first guiding tube, the cavity communicates with the air outlet in a guided mode through a second guiding tube, the far end of the first guiding tube is close to the second bottom face, and the near end of the second guiding tube is close to the first bottom face.

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...
