Problems solved by technology

[0009] Therefore, the existing hermetic compressor maintains the suction pressure significantly lower than the pressure of the compression space, whereby, as figure 2 As shown, the suction speed of the refrigerant is a maximum of 9m / sec 2 , but the noise of the refrigerant in a specific frequency band such as 4k is high about 28dBA, so it is necessary to improve the noise performance

Abstract

The present invention discloses a hermetic compressor which can reduce the noise by regulating a suction pressure in a connector enabling a suction pipe of a hermetic container and a suction muffler to communicate with each other. The hermetic compressor includes: a hermetic container including a suction pipe through which refrigerant is sucked and accommodating a compression mechanism unit for compressing the refrigerant; a suction muffler fixed to the compression mechanism unit and reducing the flow noise when the refrigerant passes; and a connector enabling the suction pipe and the suction muffler to communicate with each other and including a hole on a refrigerant passage to communicate with an inner space of the hermetic container. An inner pressure of the connector is equalized with an inner pressure of the hermetic container, which raises a refrigerant suction pressure. As a difference between the refrigerant suction pressure and the pressure of the compression space is reduced, the noise generated during the refrigerant suction can be reduced.

Description

technical field [0001] The present invention relates to a hermetic compressor, in particular to a hermetic compressor capable of reducing noise by adjusting suction pressure at a connection port connecting a suction pipe of a hermetic container to a suction muffler. Background technique [0002] In general, a hermetic compressor includes a compression mechanism unit that compresses refrigerant by reciprocating motion, an electric mechanism unit that supplies power to the compression mechanism unit, and a hermetic container that hermetically accommodates the compression mechanism unit and the electric mechanism unit. Such a hermetic compressor, as an element of a refrigeration system such as a refrigerator, performs a phase change from a low-temperature and low-pressure gas refrigerant to a high-temperature and high-pressure gas refrigerant, and this phase change can be achieved by reciprocating motion inside the cylinder. The compression force of the piston is realized. [...
