Benefits of technology

[0006]Accordingly, an aspect of the invention is to provide a hermetic type compressor in which a suction muffler substantially prevents liquid refrigerant from being suction

Problems solved by technology

Moreover, when a larger amount of the liquid refrigerant is transmitted into the suction muffler, the load applied to the compression unit to suction the refrigerant liquid increases, thereby increasing the load on the driving unit to drive the compression unit.
The increased load on the compression unit and the driving unit increases the noise of the hermetic type compressor and

Embodiment Construction

[0017]Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0018]Referring to FIG. 1, a hermetic type compressor according to an embodiment of the present invention is shown. The hermetic type compressor includes a sealed casing 1 to form an exterior, a suction pipe 2 installed on a side of the sealed casing 1 to guide refrigerant from an evaporator of a refrigeration cycle into the sealed casing 1, and a discharge pipe 3 installed on the opposite side of the sealed casing 1 to guide the refrigerant compressed in the sealed casing 1 into a condenser of the refrigeration cycle.

[0019]In the sealed casing 1, a compression unit 10 and a driving unit 20 are installed on a frame 30. The compression unit 10 is disposed substantially adjacent to a side of the frame 30, and the driving unit 20 is disposed substantially adjacent to an opposite side of the frame 30. The compression unit 10 compresses the refrigerant, and the ...

Abstract

A hermetic type compressor that includes a sealed casing, a suction pipe, a suction muffler, a compression unit, a driving unit, and a pressure adjusting unit. The suction pipe penetrates a side of the sealed casing. The suction muffler, the compression unit, and the driving unit are within the sealed casing. The suction muffler is coupled to the suction pipe, and the compression unit is coupled to suction muffler. The driving unit is coupled to the compression unit. The pressure adjusting device is on the suction muffler and configured to discharge liquid refrigerant into the sealed casing. The pressure adjusting device maintains the internal pressure of the suction muffler substantially constant.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of Korean Patent Application No. 2006-114792, filed on Nov. 20, 2006, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to a hermetic type compressor. In particular, the present invention relates to a hermetic type compressor with an improved suction muffler to restrict liquid refrigerant from being suctioned into a compression chamber. By restricting liquid refrigerant, a compression unit that compresses the refrigerant and a driving unit that provides a driving force to the compression unit are not overloaded.BACKGROUND OF THE INVENTION[0003]Generally, a hermetic type compressor is employed in a refrigeration cycle of a refrigerator, an air conditioner, and other similar devices. The refrigeration cycle includes a refrigerant, a compressor, a condenser, an expansion device, and an evaporator....
