Suction muffler for a compressor

Abstract

A suction muffler for a compressor employed in a home appliance having a refrigeration cycle reduces noise produced by the compressor. The suction muffler includes a muffler body and a refrigerant suction pipe. The muffler body defines a resonance chamber and is coupled to a refrigerant supply pipe. The refrigerant suction pipe connects the resonance chamber to a compressor cylinder. The refrigerant suction pipe has at least one hole formed in its cylindrical wall. The muffler further includes a guiding portion in the resonance chamber to direct refrigerant from the supply pipe to the at least one hole in the refrigerant suction pipe and to direct noise exiting an upper end of the refrigerant suction pipe away from the refrigerant supply pipe. The suction muffler shortens the refrigerant flow path and lengthens the noise transmission path, thereby reducing the level of noise emitted while increasing efficiency of the compressor.
