Technical Field

The invention relates to the field of variable capacity machinery, in particular to a scroll compressor.

Background

After the compressor finishes the compression like a scroll compressor, the discharged high-pressure gas is the mixed gas in an oil-gas mixing state, when the mixed gas enters the refrigeration (heating) circulation of the system, the mixed gas is influenced by pressure and temperature changes, oil in a refrigerant can gradually gather and deposit, so that the efficiency of the whole cooling system is influenced, and due to the particularity of a refrigeration (heating) circulation pipeline, the efficiency of the whole cooling system is greatly influenced.

Chinese patent document CN2811622Y discloses a scroll compressor with an oil return device for a room air conditioner; the compressor is additionally provided with a specific exhaust cavity at the exhaust port through the arrangement, a filter screen is arranged in the exhaust cavity, and oil is filtered through the particularity of the filter screen, so that the oil is collected.

Chinese patent document CN 109185128A discloses an electric compressor provided with a secondary high-efficiency oil separation structure; this patent uses the multipolar baffle for the gas of high-pressure chamber exhaust is walked in this structure to produce the collision with this structure, make the fluid in the compressor separate with the refrigerant, then return to the oil bath after collecting.

Both of the above two patents need to add a relatively complex mechanism at the exhaust end for blocking the exhaust circulation, so as to achieve the effect of oil-gas separation, but due to the volume or structure of the newly added object, the height and the processing cost of the compressor are greatly increased.
