Compressors muffler

Abstract

The invention discloses a compressor silencer, which is characterized by the following: forming a cross-shaped projecting part of crank through hole in the central part; extending outsides along the horizontal direction of projecting part to form a circular chassis structure; setting outlet hole along radial direction and through the chassis on two sides of cross-shaped projection part separately. The silencer is set on two lateral ends without setting inner plate, which avoids the noise of the rotor impaction directly.

Description

technical field [0001] The invention relates to a compressor, in particular to a compressor muffler capable of reducing impact noise and cost. Background technique [0002] Generally speaking, the rotary compressor does not rely on centrifugal force, but compresses the refrigerant through the rotation of the roller ring in the cylinder, that is, relies on the eccentric roller ring installed at the lower part of the crankshaft to rotate and revolve along the inner peripheral surface of the cylinder to compress the refrigerant.

Problems solved by technology

In this case, the refrigerant discharged from the discharge hole 13 will directly impact the rotor 22 above the muffler 38, thus generating a relatively large impact noise.

In addition, since this muffler 38 reduces noise by increasing the inner plate 12, the cost of the product will be increased.
