For realizing the object of the invention, provide following technological scheme:
Scroll compressor of the present invention comprises sealing shell, dynamic scrollwork, quiet scrollwork, bent axle, support and motor, this quiet scrollwork and support offers the folding shape groove as refrigerant flow.So just, the refrigerant flow that quiet scrollwork and support are formed is extended.Meanwhile, the existence of folding shape groove makes the mixed gas of refrigerant and refrigeration oil when flowing through this passage, and the flow direction of mixed gas changes, and flow velocity slows down greatly, improves the separation effect of refrigerant and refrigeration oil, greatly reduces the race oil mass that compressor is outside.
Preferred, this folding shape groove is distributed in the outer periphery of quiet scrollwork and support.Preferred, described folding shape groove offers at least two, and can be uniformly distributed also can uneven distribution.
The folding shape groove shape that quiet scrollwork and support are offered can not be identical, as long as ensure that the folding shape groove joint on these two parts communicates.This folding shape groove can be in > shape or < shape, forms by being separately positioned on the two lineal shape exhaust passages in opposite directions, angle of inclination that quiet scrollwork and support are connected.On quiet scrollwork and support, the inclination of lineal shape exhaust passage and width can be arranged according to actual conditions, and the width of the lineal shape exhaust passage on scrollwork as quiet in this is A, and inclination is B.More preferably, the angle of inclination of two described lineal shape exhaust passages is different.
Preferred, this folding shape groove is connected forms by being arranged on the folding shape exhaust passage that arranges on lineal shape exhaust passage and support that quiet scrollwork surface thereof arranges.More preferably, described lineal shape exhaust passage is different from the angle of inclination of folding shape exhaust passage.
Preferred, this folding shape groove forms by being arranged on the folding shape exhaust passage that quiet scrollwork and support are connected.This folding shape exhaust passage is > shape or < shape, more preferably, the angle of the tendency of the folding shape exhaust passage section of being connected of quiet scrollwork and support is different, forms wave folding shape groove, thus whole folding shape groove can be made to obtain more bending angle.When bending angle is more, the refrigerant flow that quiet scrollwork and support are formed extends more, meanwhile, more improves the separation effect of refrigerant and refrigeration oil, greatly reduces the race oil mass that compressor is outside.
Contrast prior art, the present invention has the following advantages:
Beneficial effect of the present invention is, owing to having offered folding shape groove on quiet scrollwork and support, improves the separation effect of refrigerant and refrigeration oil, greatly reduces the race oil mass that compressor is outside, improves the reliability of compressor.
