Abstract

The invention provides a compressor and an air conditioner. The compressor comprises a static static scroll plate, a movable scroll plate and an oil return structure; the oil return structure can collect lubricating oil in exhausted gas; a static scroll plate cover board covers the side, back on to the movable scroll plate, of the static scroll plate; a first lubricating oil chamber is arranged onthe side, facing the static scroll plate cover board, of the static scroll plate, the oil return structure can guide collected lubricating oil into the first lubricating oil chamber, and a compression cavity can communicate with the first lubricating oil chamber; and / or a second lubricating oil chamber is arranged on the side, facing the static scroll plate, of the static scroll plate cover board, the oil return structure can guide collected lubricating oil into the second lubricating oil chamber, and the compression cavity can communicate with the second lubricating oil chamber. According tothe compressor and the air conditioner, oil obtained after oil and gas in the exhausted gas are separated can be effectively supplied to a pump body structure of the compressor, the oil return amountand the oil return efficiency are improved, the oil return effect is improved, the oil supply efficiency is high, the reliability is high, abnormal abrasion of a scroll plate of a scroll compressor is reduced, and noise is lowered.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor and an air conditioner. Background technique [0002] The scroll compressor has the advantages of simple structure, small size, light weight, low noise, high mechanical efficiency and stable operation. Scroll compressors are complex machines operating at high speeds. Ensuring adequate lubrication of moving parts such as compressor crankshafts, bearings, and scroll disks is the basic requirement for maintaining the normal operation of the machine. However, due to negligence in refrigeration system design, construction and maintenance, lack of oil in the compressor, oil coking and deterioration, return liquid dilution, refrigerant flushing, use of inferior lubricating oil, etc. cause insufficient lubrication of moving parts. Lack of oil and insufficient lubrication will cause wear or scratches on the bearing surface, and in severe cases, it will cause shaft holdin...
