Compressor exhaust structure and compressor with the exhaust structure

Abstract

The invention discloses a compressor exhaust structure and a compressor with the exhaust structure. The compressor exhaust structure comprises: a closed casing with an oil storage pool for storing lubricating oil at the bottom of the inner cavity; The component is arranged at the bottom of the inner cavity of the airtight casing, and the compression component has an exhaust port; the sound-absorbing cavity is arranged above the compression component, and the sound-absorbing cavity is connected with the exhaust port of the compression component; it also includes: an exhaust channel, one end It communicates with the sound-absorbing cavity, and the other end communicates with the oil storage tank. In the compressor exhaust structure of the present invention, the muffler cavity is communicated with the oil storage pool at the bottom of the housing cavity through the exhaust channel, so that the high-pressure gas compressed in the cylinder enters the oil storage pool through the exhaust channel, and the liquid is more Strong sound absorption ability, effectively absorbing the airflow noise discharged into the oil pool, especially the high-frequency components, which makes the exhaust airflow pulsation noise dull, thus effectively improving the sound quality of the compressor.

Description

technical field [0001] The invention relates to a compressor, in particular to a compressor exhaust structure and a compressor with the exhaust structure. Background technique [0002] The sound quality of compressors has attracted more and more attention from home appliance manufacturers, and has been mentioned as equally important as the energy efficiency of refrigeration and heating. As the exhaust noise is an important part of the total noise of the compressor, its exhaust method has a great impact on the compressor. has a large impact on the overall noise. [0003] The exhaust method of the existing rotary compressor is as follows: figure 1 As shown, part of the compressed high-pressure gas is discharged into the upper muffler through the upper flange, and then discharged into the cavity of the shell through the upper muffler; The orifice on the flange and cylinder then drains into the housing cavity. In this exhaust method, when the high-pressure gas is discharged f...

AI Technical Summary

Problems solved by technology

In this exhaust method, when the high-pressure gas is discharged from the muffler or the exhaust port on the flange, the sudden change in the flow area will cause severe airflow pulsation, resulting in obvious airflow pulsation noise, and the frequency component of aerodynamic noise is relatively high , the ear feels sharp and the sound quality is poor
