Background
In the operation process of the compressor, due to the high-temperature and high-pressure environment of the compressor, the refrigerant oil is required to be lubricated and cooled so as to reduce the friction loss in the working process of the compressor. After the refrigerant oil enters the refrigeration system along with the refrigerant, the performance of the system can be influenced to a certain extent. The refrigerant is mixed with the refrigeration oil, so that the evaporation temperature of the refrigerant is increased, and the evaporation temperature is gradually increased along with the increase of the oil content. If the evaporation temperature rises, the heat transfer temperature difference is reduced, directly resulting in the reduction of the refrigerating capacity of the evaporator. The refrigerant oil mixed in the refrigerant condenses on the surface of the condenser to form an oil film. In the evaporator, the refrigerant oil is difficult to evaporate and forms an oil film, thereby also influencing the heat exchange between the condenser and the evaporator and reducing the capacity of the refrigerating system.

The present invention is illustrated in detail below by means of specific examples.
In a first aspect, referring to fig. 1 and 2, the invention discloses an oil-gas separation device for a compressor, which comprises an oil baffle 100 and a bearing 200. Referring to fig. 3 and 4, the oil deflector 100 is provided with a plate body 110 and a fitting portion 120, and the plate body 110 is provided with a plurality of air holes 111. The fitting portion 120 is fixed to the bearing 200, and the oil deflector 100 is rotatably fitted between the motor 300 of the compressor and the pump body assembly 500 through the bearing 200. After the high-pressure oil-gas mixture is discharged from the pump body assembly 500, the oil baffle 100 is pushed to rotate, gas passes through the gas hole 111, and oil is thrown and falls to the oil return channel by the oil baffle 100.
Specifically, since the rotation of the oil deflector 100 is driven by gas, the bearing 200 may be a low resistance bearing in order to reduce loss. The bearing 200 includes an inner ring and an outer ring, the inner ring is connected to the flange journal 401, the outer ring is connected to the inside of the assembling portion 120, the inner ring and the outer ring of the bearing 200 rotate relatively, in actual assembly, the inner ring and the flange journal 401 are fixed, the outer ring and the assembling portion 120 are fixed, and the fixing mode can adopt but is not limited to interference connection. In other embodiments, the bearing 200 may be replaced by other components such as a shaft sleeve, which should ensure that the oil deflector 100 rotates smoothly at a predetermined position to prevent the oil deflector 100 from jumping in the axial direction. In order to improve the stability of the oil deflector 100 when rotating, the oil deflector 100 may be provided in a ring structure.

Moreover, the rotation of the oil baffle plate 100 does not need a power device, the oil baffle plate can rotate after the compressor starts to operate to generate air pressure, oil is thrown out by the rotation of the oil baffle plate 100, the oil-air separation is accelerated, and the power consumption influence of the compressor is reduced. Therefore, this application need not to increase power, can also realize oil-gas separation before the motor, still improved the oil-gas separation effect when the consumption reduces.
In a preferred embodiment, considering that the output of the high-pressure mixture may cause unstable rotation of the oil baffle 100 and large speed variation, a guiding structure may be disposed on one side of the oil baffle 100 facing the pump body assembly 500, for example, a boss or a groove may be disposed along the rotation center of the plate body 110, so that the boss or the groove forms a structure similar to a propeller, so that the vertical pressure of the high-pressure mixture on the plate body 110 is converted into a circumferential driving force on the plate body 110, thereby rotating the oil baffle 100 clockwise or counterclockwise, and ensuring an oil slinging effect.
