Lower shell structure for refrigerator compressor

Abstract

The invention discloses a lower shell structure for a refrigerator compressor. The lower shell structure comprises a lower shell body assembly, a limiting top plate assembly, a compressor body positioning assembly, a positioning supporting assembly and a line source positioning unit, the limiting top plate assembly is arranged on the inner side of the top end of the lower shell body assembly and is in rotatable separation connection with the inner side of the top end of the lower shell body assembly, the compressor body positioning assembly is mounted at the bottom end of the inner side of thelower shell body assembly, and the positioning supporting assembly is arranged at the bottom end of the outer side of the lower shell body assembly and connected with the bottom end of the outer sideof the lower shell body assembly through welding. The limiting top plate assembly can be fixedly and rotatably connected with an upper shell structure and the lower shell structure to achieve the effect of a connecting link between the preceding and the following, and fixity of the compressor in a lower shell assembly is further improved; and heat dissipating through holes are formed in a limiting top plate, thus a compressor body can dissipate heat through the heat dissipating through holes in the upper shell structure and the lower shell structure, filter nets are mounted in the heat dissipating through holes, the hole diameters of the filter nets are each 0.3-0.55 mm, impurities can be effectively prevented from entering the compressor through the shell structures, and overall operation of the structure is ensured.

Description

technical field [0001] The invention relates to the technical field of refrigerator accessories, in particular to a lower casing structure for a refrigerator compressor. Background technique [0002] A compressor is a driven fluid machine that elevates low-pressure gas to high-pressure gas, and is the heart of the refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. The lower shell shell structure is used for It is used in conjunction with the compressor to protect the structure of the compressor. The structure design of the existing lower shell structure for refrigerator compressors is unreasonable.

Problems solved by technology

It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. The lower shell shell structure is used for It is used in conjunction with the compressor to protect the structure of the compressor. The structure design of the existing lower shell structure for refrigerator compressors is unreasonable. The lower shell shell structure and the upper shell shell structure are fixed by two connecting bolts. It is extremely unstable. During transportation, the upper shell structure and the lower shell structure at the outer end of the compressor are prone to friction and collision; the fixing bolts will collide with the upper shell. When the transportation distance is too long , when there are too many collisions, the bolts will loosen, causing the compressor to leak air, and if the lower shell structure or the upper shell structure is fixed, it will make it extremely difficult for the staff to repair and disassemble, and it will consume manpower and material resources. , there is an urgent need for those skilled in the art to design a new type of lower shell shell structure for refrigerator compressors
