Refrigerator compressor and oil filter device

Abstract

The invention relates to a refrigerating compressor of a refrigerator and provides an oil filter device of a refrigerator compressor. The oil filter device comprises a housing and a magnetic filter device, wherein the housing comprises an upper housing and a lower housing which are hermetically connected; and the magnetic filter device is a magnet block fixed to the inner bottom of the lower housing of the compressor. The oil filter device is applied to the conventional refrigerating compressor. The oil filter device has the following outstanding substantial characteristics and remarkable progresses: the magnet block is mounted at the bottom (namely the position of an oil pool) of the lower housing, and influence on the operation of the compressor is completely avoided, so that a ferrous material in oil is adsorbed onto the magnet block through the magnetic adsorption effect of the magnet block on the ferrous material when the compressor is in operation, which ensures that the ferrous material can not enter into a refrigerant circulating system any more, guarantees normal running of important parts such as a piston, an air cylinder, a valve plate, a capillary tube and the like, and prolongs the service life of the compressor.

Description

technical field [0001] The invention relates to a refrigeration compressor of a refrigerator. Background technique [0002] Refrigeration compressors of refrigerators are usually fully enclosed, and their structure refers to figure 1 , mainly including a casing and a movement installed in the casing, the casing includes an upper casing 11 and a lower casing 12; [0003] Movement comprises support 21, cylinder block 22, crankshaft, motor stator 70, rotor 7 and movement mounting bolt 71, and cylinder block 22 connects to support 21, and the cylinder 20 built-in piston 3 of cylinder block 22, motor stator 70 comprises stator iron core and the stator winding wound around the stator core, the stator core is fixedly connected to the bottom of the bracket 21 through the movement mounting bolt 71, and the middle part of the bracket 21 is provided with a shaft hole; [0004] The crankshaft includes a crankshaft part 5, a balance part 51 and a main shaft part 6. The main shaft part ...

AI Technical Summary

Problems solved by technology

[0009] When the existing compressor is working, there are inevitably various impurities in the pipeline of the refrigeration system, including iron materials, which will enter the lubricating oil pool and then be supplied to the moving parts with the lubricating oil , so that the moving parts (piston 3, cylinder 20, crankshaft, valve plate, etc.) will be worn and the service life of the compressor will be shortened
