Problems solved by technology
The noise reduction of the compressor is mainly achieved through the silencer of the suction muffler. Miniaturization will compress the space of the suction muffler, and the reduction of the cavity volume of the suction muffler will reduce the suction efficiency of the compressor and affect the performance of the compressor. Noise reduction effect
At present, most miniaturized compressor suction mufflers adopt a relatively simple intubation structure, the noise reduction effect is not ideal, and the compressor suction efficiency is low

The invention discloses a suction silencer and a compressor provided with the suction silencer. The suction silencer comprises a lower shell, a partition plate, an air guide pipe and an upper shell, wherein a first cavity is defined in the lower shell, the upper end of the first cavity is open, the lower shell is provided with a suction pipe communicated with the first cavity, the partition plate is arranged on the lower shell and seals the first cavity, the air guide pipe is arranged in the first cavity and provided with a suction end and an exhaust end, the suction end is communicated with the suction pipe, the exhaust end penetrates through the partition plate to extend upwards, the upper shell is arranged on the lower shell, the lower end of the upper shell is open, a second cavity and a second cavity which are arranged in a spaced mode are defined between the upper shell and the partition plate, the upper shell is provided with an exhaust pipe communicated with the third cavity, the exhaust end of the air guide pipe penetrates through the second cavity and extends into the third cavity, and the air guide pipe is provided with a first resonance hole communicated with the second cavity. According to the suction silencer, the noise level of the suction silencer can be decreased on the premise of ensuring the suction efficiency of the suction silencer.
Description
technical field [0001] The present invention relates to the technical field of refrigerating compressors, more specifically, to a suction muffler and a compressor having the same. Background technique [0002] As miniaturized refrigerators are more and more favored by customers, refrigerator compressors are also getting smaller and smaller. The miniaturization of the compressor brings a series of problems, such as the reduction of the suction efficiency and the increase of the noise, etc., and the noise has always been an important performance parameter for evaluating the performance of the compressor. The noise reduction of the compressor is mainly achieved through the silencer of the suction muffler. Miniaturization will compress the space of the suction muffler, and the reduction of the cavity volume of the suction muffler will reduce the suction efficiency of the compressor and affect the performance of the compressor. Noise reduction effect. At present, most miniaturi...
