Problems solved by technology

[0003] However, due to space constraints, the spatial structure layout of the muffler above the main bearing or below the sub-bearing is limited, resulting in limited performance of the muffler, and the noise of the exhaust airflow of the compressor is still relatively large

Abstract

The invention discloses a compressor and an air conditioner and relates to the technical field of air conditioners. The compressor comprises a first bearing, a second bearing, a compression cylinder,a first silencer and a second silencer; the compression cylinder is located between the first bearing and the second bearing, and is provided with a fluid outlet; the first silencer is located betweenthe first bearing and the second bearing, and is provided with a first silencing cavity; the second silencer is located on the side, deviating from the second bearing, of the first bearing, and is provided with a second silencing cavity; and the fluid outlet, the second silencing cavity and the first silencing cavity communicate with one another in sequence. The air conditioner comprises the compressor. The first silence and the second silence perform two-time denoising on fluid, gas flow noise of the compressor can be lowered easily, and the denoising performance of the compressor is improved. In addition, due to the arrangement of the first silencer, the structural size of the compressor cannot be increased, it is achieved that the denoising performance is improved on the premise that the structural size of the compressor is not increased, and miniaturization design of the compressor is facilitated.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a compressor and an air conditioner. Background technique [0002] When the compressor is working, due to the characteristics of its working principle, there is inevitably noise influence. The noise of the compressor is generated in many ways, including airflow noise, mechanical noise and electromagnetic noise. Among them, the airflow noise is a main noise source of the compressor, and the noise is mainly caused by the high-pressure fluid pulsation discharged from the compression chamber. In the prior art, in order to reduce the noise of the exhaust air flow of the rotary compressor, a muffler is usually installed above the main bearing or below the auxiliary bearing. The high-pressure fluid discharged from the compression chamber first flows through the muffler for noise reduction, and then from the compressor Fluid outlet discharge. [0003] However, due to space con...
