Silencer with balancing chamber

Abstract

The invention relates to a silencer with a balancing chamber, which consists of a silencer cavity, a cavity sealing cover, and an internal communicating pipe. The cavity sealing cover is fixed on the silencer cavity; the internal communicating pipe is clamped in a cavity formed after the fixation of the silencer cavity and the cavity sealing cover; one side of the silencer cavity is provided with an air suction port; the lower bottom of the silencer cavity is provided with an oil leakage hole; the cavity sealing cover is provided with an air outlet; and one end of the internal communicating pipe is communicated with the air suction port, while the other end is communicated with the air outlet, wherein the balancing chamber is separated in the silencer cavity on the other side of the air suction port of the silencer cavity through a partition, a lower bottom plate in the balancing chamber is provided with a balancing hole, and the balancing chamber is communicated with the silencer cavity. The silencer has a simple integral structure as well as scientific and reasonable design, can effectively reduce the negative pressure in the silencer cavity during the air suction of a compressor, reduce the whole noise of the compressor, and improve the stability of the compressor, and has higher novelty and is provided with the balancing chamber.

Description

technical field [0001] The invention belongs to the muffler in the field of compressors, in particular to a muffler with a balance cavity. Background technique [0002] Refrigeration household appliances not only need to have a good cooling effect, but also low energy consumption and low noise are the goals pursued by people. The noise of refrigeration household appliances mainly comes from the operation of the compressor, which is the vibration noise generated by the compressor during the intermittent refrigeration process. This periodic vibration noise brings certain troubles to people's daily life. In order to reduce the noise of the compressor, a muffler is currently fixed on the cylinder head of the compressor. The muffler is generally composed of a muffler cavity, a cavity cover and an internal connecting pipe installed in it. There is a suction port, and the air outlet is made on the cavity cover, and the two ends of the inner connecting pipe are respectively connect...

AI Technical Summary

Problems solved by technology

Although this muffler structure can reduce the noise of the compressor to a certain extent, there are still the following problems: (1). During the suction process of the piston cylinder of the compressor, negative pressure is easily generated in the muffler cavity, which causes the muffler to compress The machine casing moves in the direction, or even collides, which greatly reduces the stability of the compressor; (2). The negative pressure in the muffler cavity may cause the lubricating oil dripping from the oil leakage hole on the bottom of the muffler cavity to pour suction, which is not conducive to the discharge of lubricating oil from the muffler; (3). The noise reduction ability of the entire cavity is poor, which cannot meet the needs of technological development
