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...
