Abstract

The present invention provides a compressor for improving refrigeration capacity and efficiency by increasing volumetric efficiency, wherein the suction muffler (140) is provided with: a main body forming a sound-absorbing space, opening in a sealed container (101) and connecting with the sound-absorbing space The communicating suction port and the gas receiving part (144) are arranged to surround the above-mentioned suction port and have an opening surface (146) on the side opposite to the opening end (145) of the suction pipe (109). By arranging the lower end of the opening end of the suction pipe (109) below the lower end of the opening surface of the gas receiving part (144), the low-temperature, denser gas released from the suction pipe (109) into the airtight container (101) can be The retention amount of refrigerant gas in the inner space of the gas receiving part (144) is increased, thereby improving refrigeration capacity and efficiency can be expected.

Description

technical field [0001] The present invention relates to a compressor, and more particularly to an improvement of a compressor suction muffler mainly used in refrigeration equipment such as a refrigerator. Background technique [0002] In the existing compressors, a suction muffler is generally installed in the suction flow path, one is to reduce the temperature of the refrigerant gas, and the other is to efficiently suck the refrigerant gas returned from the external cooling circuit into the Suction into the muffler (for an example, please refer to Japanese Patent Publication No. 2002-161855). [0003] The above-mentioned conventional compressor will be described below with reference to the accompanying drawings. [0004] Figure 7 is a cross-sectional view of the existing compressor shown in the above reference, Figure 8 It is a sectional view of the suction muffler in the conventional compressor. [0005] Such as Figure 7 , 8 As shown in , the airtight container 1 is...
