Abstract

Disclosed herein is a hermetic compressor. The hermetic compressor includes a suction muffler. The suction muffler includes an inlet part and a refrigerant guide pipe. The inlet part has a shape of a semi-flare pipe, and is spaced apart from an inlet pipe. The refrigerant guide pipe extends from an interior of a resonance chamber to communicate with a compression chamber. An expanding part having an enlarged diameter is provided at an inlet of the refrigerant guide pipe. The inlet part and the expanding part allow noises produced in the compression chamber to be doubly diffused, thus efficiently reducing the noises.

Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of Korean Patent Application No. 2003-91119, filed Dec. 15, 2003 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference. BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates, in general, to hermetic compressors and, more particularly, to a suction muffler of a hermetic compressor, which draws a gas refrigerant of a low pressure passing through an inlet pipe into a compression chamber of a cylinder block.

[0004] 2. Description of the Related Art

[0005] Generally, hermetic compressors are widely used in refrigeration systems, such as a refrigerator, to compress a refrigerant. A conventional hermetic compressor includes a hermetic casing to define a hermetic space, with a compressing unit to compress a refrigerant and a drive unit to drive the compressing unit being installed in the hermetic casing.
