Problems solved by technology

The mixed gas of refrigerant and refrigerating oil passes through the gap between the fixed scroll, the bracket and the shell, guides it between the bracket and the motor parts, and finally discharges from the exhaust pipe to the outside of the compressor, but a considerable part

Embodiment Construction

[0018] see figure 1 , the motor in the scroll compressor of the present invention drives the crankshaft 5 to rotate, and the crankshaft 5 drives the movable scroll 3 to revolve around the static scroll 2, so a series of crescents are formed between the movable scroll 3 and the static scroll 2 Space, as the crescent-shaped space in the outer circle moves toward the center, at this time, the refrigerant is gradually pushed to the center space, its volume shrinks and the pressure continues to rise, until it communicates with the exhaust channel 2a, the high-pressure and high-temperature refrigerant is exhausted Passage 2a discharges into the seal cavity of the scroll compressor.

[0019] exist figure 1 In , the solid arrows indicate the flow of refrigerant oil, and the hollow arrows indicate the flow of refrigerant. The mixed gas of refrigerating oil and refrigerant discharged from the exhaust passage 2a is guided between the bracket 4 and the motor parts through the gap betwee...

Abstract

The invention discloses a scroll compressor comprising a closed shell, a movable scroll, a fixed scroll, a crank shaft, a bracket and a motor, wherein the fixed scroll and the bracket are provided with a bent chute used as a refrigerant flow path. Thus, the refrigerant flow path formed on the fixed scroll and the bracket can be prolonged. Meanwhile, due to the existence of the bent chute, when a mixed gas of refrigerant and refrigeration oil flows through the passage, the flowing direction of the mixed gas is changed, the flow speed is greatly reduced, the separation efficiency of the refrigerant and the refrigeration oil is increased and the outward oil leakage amount of the compressor is greatly reduced.

Description

【Technical field】 [0001] The invention relates to a compressor, in particular to a new scroll compressor structure. 【Background technique】 [0002] Scroll compressors are widely used in the fields of refrigeration, air conditioning and heat pumps because of their high efficiency, small size, light weight and stable operation. Generally speaking, a scroll compressor is composed of a closed casing, an orbiting scroll, a static scroll, an Oldham slip ring, a crankshaft, a bracket, and a motor. The profiles of the movable and static scrolls are both helical, and the movable scroll is eccentrically installed relative to the static scroll with a difference of 180 degrees. ), the end of the scroll body shape line is in contact with the bottom of the opposite scroll body, so a series of crescent-shaped spaces are formed between the dynamic and static scrolls, that is, the elementary volume. When the movable scroll takes the center of the static scroll as the center of rotation and...
