The invention provides a double-cylinder compressor air suction resonance noise silencing structure and a compressor. The noise silencing structure comprises a first air cylinder and a second air cylinder, wherein a first air suction passage is arranged in the first air cylinder; a second air suction passage is arranged in the second air cylinder; the first air suction passage and the second air suction passage are mutually communicated so as to form a noise silencing passage. The scheme provided by the invention has the advantages that the effects of two resonance noise silencing structures can be achieved by only designing one resonance cavity; two resonance frequencies are realized; good noise silencing effects are achieved near the two resonance frequencies; the advantages of processing convenience, high speed, few processing parts, simple working procedures and low cost are realized.
Description
technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a double-cylinder compressor suction resonance noise reduction structure and the compressor. Background technique [0002] Such as figure 1 As shown, in the typical structure of the twin-cylinder rolling rotor compressor in the prior art, due to the intermittent suction of the compressor and the backflow of the refrigerant in the high-pressure chamber, there will be serious suction pulsation during the suction process of the compressor; On the one hand, it produces a large suction noise, on the other hand, it affects the effective suction volume of the compressor. [0003] In order to improve the noise caused by the suction pulsation of the rolling rotor refrigeration compressor, it is an effective solution to set up a resonance and noise reduction structure at the suction port of the pump body; the patent of Chinese patent application No. CN201020226212.9 sets t...
