Refrigerator and its compressor

Abstract

The invention provides a compressor. The compressor comprises a casing, an oil pump and a guide isolation assembly, wherein an oil sump for containing lubricating oil is arranged at the bottom part of the casing; the oil pump is arranged in the casing; the guide isolation assembly is arranged at the bottom part of the casing, and is positioned under the oil pump; the guide isolation assembly comprises an isolation part, the isolation part comprises at least two isolation parts of which the cross sections are of sealed structures, the at least two isolation parts are sheathed by layers, and an isolation groove is formed between the adjacent isolation parts; the oil pump is used for sucking the lubricating oil, and the isolation parts are used for isolating the impurities of the lubricating oil into the isolation groove. The compressor has the advantages that the guide isolation assembly is used for effectively blocking most of impurities from entering an oil path system, the running risk of the compressor is effectively decreased, the abrasion of the moving parts of the compressor due to impurities is avoided, the long-time running of the compressor is safer and more reliable, and the reliability of the compressor is improved. The invention also provides a refrigerator.

Description

technical field [0001] The invention relates to the technical field of refrigerator equipment, in particular to a refrigerator and a compressor thereof. Background technique [0002] At present, the refrigerators produced use reciprocating piston compressors. Generally, most reciprocating piston compressors do not use an oil filter device on the oil circuit. The main reason is that the structure of this oil filter device is complicated, the installation is troublesome, and the additional cost is increased. Reciprocating piston compressors usually control oil circuit impurities by controlling the cleanliness of the production process. However, for a newly installed compressor, the compressor has not been run-in. After a long period of operation, the moving parts of the compressor will wear each other, and dust or fine particles will be generated, which makes the long-term operation of the compressor safe. Hidden dangers affect the reliability of the compressor. Contents o...

Problems solved by technology

[0003] Based on this, it is necessary to provide a compressor that can effectively prevent most impurities from entering the oil circuit system, reduce the wear of moving parts, and ensure safe operation in view of the problem that impurities in the current lubricating oil easily enter the oil circuit and cause potential safety hazards in the compressor. Reliable compressor, while also offering a refrigerator containing the above compressor
