Abstract
Disclosed is a reciprocating compressor having an assembly structure of a suction muffler, in which a supporting unit is formed on an inner circumferential surface of a resonant container of the suction muffler and a baffle is assembled in the resonant container by the supporting unit. By forming protrusions in the resonant container and inserting a baffle between the protrusions, the suction muffler can be easily and simply assembled. Accordingly, production costs can not only be reduced but also an increased noise reduction effect is obtained by precisely regulating an assembly position.
Claims8
A reciprocating compressor having an assembly structure of a suction muffler, comprising:
- a casing for connecting a gas suction pipe with a gas discharge pipe;
- a frame elastically installed in the casing;
- a reciprocating motor supported by the frame;
- a piston coupled with a mover of the reciprocating motor and compressing a refrigerant gas while linearly reciprocating in a cylinder;
- a suction valve for opening or closing a suction flow channel of the piston;
- a discharge valve for opening or closing a discharge side of the cylinder;
- a plurality of resonance springs for elastically supporting the piston in a direction of motion and inducing the resonance movement;
- and
- a suction muffler coupled with the piston and guiding the refrigerant gas to the suction flow channel of the piston and simultaneously muffling a suction noise generated when opening or closing the suction valve,
- wherein a supporting unit is formed on an inner circumferential surface of a resonant container of the suction muffler and a baffle is supported in the resonant container by the supporting unit,
- wherein the supporting unit comprises a first protrusion and a second protrusion, and an insertion groove is formed between the first and second protrusions along the inner circumferential surface of the resonant container, and
- wherein the first protrusion has a setting height lower than a setting height of the second protrusion in order to permit insertion of the baffle past the first protrusion and into the insertion groove.
