Abstract
A reciprocating compressor includes a suction muffler including a partition wall that partitions an inner space of the suction muffler into multiple spaces. The suction muffler further includes a guide pipe that is provided at the partition wall and that defines a resonance hole configured to reduce noise in a specific band.
Claims20
A reciprocating compressor comprising:
- a cylinder;
- and
- a suction muffler configured to receive refrigerant and to supply the refrigerant to the cylinder, the suction muffler comprising:
- a suction muffler body that defines a suction space configured to receive the refrigerant, the suction muffler body further defining a suction hole,
- a suction pipe portion that is disposed inside the suction muffler body and extends from the suction hole,
- a partition wall that is disposed at the suction muffler body and partitions the suction space into a first space and a second space, and
- a guide pipe that is disposed at the partition wall and defines a refrigerant passage in fluid communication with the first and second spaces, the guide pipe being separably coupled to the suction pipe portion, wherein the guide pipe comprises:
- a first pipe portion that extends from the partition wall to the first space and has a circumferential surface defining a resonance hole, the first pipe portion having a first end that is in fluid communication with the suction pipe portion and configured to introduce the refrigerant suctioned through the suction hole, and
- a second pipe portion that extends from the partition wall to the second space, the second pipe portion having a second end that is configured to discharge the refrigerant from the guide pipe to the second space, and
- wherein the suction pipe portion is in contact with the first end of the first pipe portion to thereby support the first pipe portion.
