[0011] Accordingly, it is an aspect of the present invention to provide a hermetic compressor whi

Problems solved by technology

However, the conventional hermetic compressor is constructed so that the noises are deadened in the resonance chamber provided in the suction muffler.
Thus, the conventional hermetic compressor has a problem in that the noises are not completely absorbed in the resonance chamber, but some noises are released to an

Embodiment Construction

[0020] Reference will now be made in detail to the present preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiment is described below in order to explain the present invention by referring to the figures.

[0021]FIG. 1 is a sectional view of a hermetic compressor, according to an embodiment of the present invention. Referring to FIG. 1, the hermetic compressor includes a hermetic casing 10, with a compressing unit 20 and a drive unit 30 being installed in the hermetic casing 10. The compressing unit 20 compresses a refrigerant, and the drive unit 30 generates a power to drive the compressing unit 20.

[0022] The compressing unit 20 includes a cylinder block 21 to define a compression chamber 21a therein. A piston 22 is received in the compression chamber 21a, and rectilinearly reciprocates in the compression chamber 21a to draw, compress, and discha...

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. [0006] The co...
