Abstract

The invention provides a compressor comprising a shell, a stator core, a rotor core and a first baffle, wherein the stator core and the rotor core are arranged in the shell; the stator core is arranged around the rotor core; circulating holes formed along the axial direction of the rotor core are formed in the rotor core; and the first baffle comprises a bottom plate part and an oil retaining side edge arranged at the upper side of the bottom plate part, and the first baffle is opposite to the upper end surface of the rotor core, so that lubricating oil carried by a refrigerant comes into collision with the oil retaining side edge to form oil drops falling back below the rotor core after the refrigerant flowing out of the circulating holes passes through the bottom plate part. By using the compressor, the refrigerant can return from the upside to the downside of a motor of the compressor, so that the stroke of the refrigerant is increased; in addition, due to the adoption of the design of the non-swirl baffle located above the rotor core, an extremely good oil retaining effect is taken while no wind resistance is generated, and the condition that the lubricating oil is discharged from the compressor is avoided, so that the oil throughput rate of the compressor is effectively reduced, the performance of a unit is improved, and the power consumption of the compressor is reduced.

Description

technical field [0001] The invention relates to the field of fluid compression, in particular to a compressor. Background technique [0002] In the rolling rotor compressor, in order to reduce the oil discharge rate to improve the performance of the compressor and air conditioner, it is mainly realized by designing the structure of the stator and rotor of the motor, the height of the shell and the structure of the oil baffle above the rotor. [0003] The first two change the flow area and flow direction of the refrigerant from the bottom to the top of the motor, thereby changing the flow rate of the refrigerant, so that the refrigerant is slowly adsorbed on the surface of the structure. [0004] However, in the prior art, the flow path of the refrigerant is unreasonably designed, and there is only a single path between the motor and the casing, ignoring the flow path of the refrigerant inside the rotor. When the concentration of lubricating oil in the refrigerant is high, t...
