Abstract

The invention provides a variable-volume silencer and a compressor, relates to the technical field of silencers, and solves the technical problem existing in the prior art that gas discharged from a flange can have a certain impact on the top of a silencer, a cavity of the existing silencer is usually changeless, and the buffering effect on the impact airflow is difficult to achieve. The variable-volume silencer comprises a movable silencing part, a silencing fixing part and an elastic structure, wherein the silencing fixing part is fixedly connected with the flange, the silencing fixing partsleeves the movable silencing part, one end of the elastic structure is connected with the movable silencing part, the other end of the elastic structure is fixed, and airflow entering the silencer from a flange air exhaust inlet can impact the movable silencing part to enable the movable silencing part to move to the direction away from the flange so as to increase the volume of the silencer. Thesilencer is used for reducing the noise of the compressor.

Description

technical field [0001] The invention relates to the technical field of mufflers, in particular to a muffler with variable volume and a compressor provided with the muffler. Background technique [0002] After the motor of the rotary compressor is energized, the rotor rotates, which in turn drives the crankshaft to rotate. The crankshaft drives the piston in the cylinder to rotate to compress the refrigerant in the cylinder. The compressed refrigerant can be discharged through the exhaust hole on the flange and enter the muffler. Exhaust from the exhaust port on the flange. [0003] The applicant finds that the prior art has at least the following technical problems: [0004] In the rotary compressor, the air flow noise is one of the main noise components of the compressor. Generally, it is due to the high flow rate of the gas discharged from the flange during the exhaust process of the rotary compressor, which has a certain impact on the top of the muffler. Noise is genera...
