Embodiment Construction

[0023] Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.

[0024] refer to figure 1 , figure 1 A hermetic compressor according to an exemplary embodiment of the present invention is shown. The hermetic compressor includes a hermetic container 10 forming its appearance. The suction pipe 11 is provided at one side of the closed container 10 for guiding the refrigerant having passed through the evaporator in the refrigeration cycle into the closed container 10 . In addition, a discharge pipe 12 is provided on the other side of the closed container 10 for guiding the refrigerant compressed in the closed container 10 to the condenser in the refrigeration cycle.

[0025] A compression unit 20 for compressing refrigerant and a driving unit 30 for generating driving force required for compressing refrigerant are ins...

Abstract

A hermetic compressor having improved configuration of a cylinder head to more efficiently attenuate noise and vibration of refrigerant discharge. The hermetic compressor includes a cylinder block having a compression chamber in which a piston rectilinearly reciprocates, and a cylinder head coupled with the cylinder block to hermetically seal the compression chamber. The cylinder head has a suction chamber and discharge chamber, which are partitioned from each other. The suction chamber serves to guide a refrigerant to be introduced into the compression chamber, and the discharge chamber serves to guide the refrigerant, which was delivered from the compression chamber after being compressed in the compression chamber, to the outside. The hermetic compressor also includes a valve device interposed between the cylinder block and the cylinder head, to control movement of the refrigerant from the suction chamber to the compression chamber or from the compression chamber to the discharge chamber. A partition member having a bore is detachably mounted in the cylinder head, to divide the discharge chamber into two parts, in order to integrally define a Helmholtz resonator in the discharge chamber.

Description

technical field [0001] The present invention relates to a hermetic compressor, and more particularly, to a hermetic compressor in which the structure of a cylinder head is improved to more effectively attenuate noise and vibration of refrigerant discharge. Background technique [0002] Generally, a hermetic compressor is used as a refrigerant compression unit employed in a refrigeration cycle of a refrigerator or an air conditioner. The hermetic compressor includes a hermetic container forming its appearance, and a suction pipe and a discharge pipe provided on opposite sides of the hermetic container, respectively. The suction pipe is used to guide the refrigerant passing through the evaporator in the refrigeration cycle into the closed container. The discharge pipe is used to guide the refrigerant compressed in the closed container to the condenser in the refrigeration cycle. [0003] In addition, a compression unit for compressing the refrigerant and a driving unit for g...
