Silencing device of compressor

Abstract

This invention provides a sound suppressor of a compressor including a double layer of an internal sound suppressor and an external sound suppressor with exhaust outlets above the upper bearing with exhaust outlet, among which, the exhaust outlet position of the intenal sound suppressor is set at the place taking the outlet of the upper bearing as the base point rotating counter-clock-wise to the third phase to prolong the flowing path of gas in the inteal layer sound suppressor. The outer sound suppressor is a three flap for increaisng its cavity volume. The distance between two rows of gas holes of the outer suppressor is designed equalizing to the odd times of half-wavelength of the bearing eliminated noise frequency and in opposite phase to the flown sound wav from the hole.

Description

technical field [0001] The invention relates to a compressor, in particular to a compressor muffler which improves the structure of the compressor muffler. Background technique [0002] Rotary compressors are widely used in refrigerators, air conditioners and other electrical equipment. The rotary compressor sucks the gaseous refrigerant evaporated by the evaporator, compresses it to the rated pressure, and then discharges it to the working system of the refrigerant. The rotary compressor can A compressor that continuously sucks in and discharges refrigerant. [0003] figure 1 is a longitudinal sectional view of an existing compressor, figure 1 The compressor indicated in is a rolling rotor rotary compressor, which is represented by figure 1 As shown, the rotary compressor has a closed casing 10, the stator 21 and the rotor 22 of the rotary compressor motor are installed on the top of the casing 10, the eccentric shaft 30 is fixed in the middle of the rotor 22, and the cy...

AI Technical Summary

Problems solved by technology

Since the shape of the outer muffler 82 is the same as that of the inner muffler 81 and is a five-lobe structure, the inner space of the outer muffler 82 is small, and the muffler is performed by expanding the volume, and the muffler effect is not good, especially for special frequency bands. Noise, the noise reduction effect is worse

[0009] The structure of the existing muffler 80 is relatively simple, and the internal space of the muffler is small, and the noise reduction effect is not good by expanding the volume, especially for the noise of special frequency bands, the noise reduction effect is even worse
