Document Type and Number:

WIPO Patent Application WO/2023/240969

Kind Code:

A1

Abstract:

An oil return structure of a compressor, a compressor, and an air conditioner. The oil return structure of a compressor comprises: a static disc (2) and a cover body (1); the end surface of the static disc (2) facing the cover body (1) is provided with a first protrusion (21) protruding towards the cover body (1), and/or the end surface of the cover body (1) facing the static disc (2) is provided with a second protrusion (110) protruding towards the static disc (2); the first protrusion (21) matches the cover body (1), or the second protrusion (110) matches the static disc (2), or the first protrusion (21) matches the second protrusion (110), so as to define, around the inner periphery of the protrusion, a cavity for gas discharging and/or oil separation; the inner periphery of the cover body (1) and the outer periphery of the protrusion jointly define an oil storage cavity (100) capable of being used for oil storage; and the oil storage cavity (100) is located on the radial outer side of the cavity for gas discharging and/or oil separation. According to the oil return mechanism of a compressor, the oil storage cavity is effectively formed, and the weight and the size of the compressor are not increased while an oil storage volume for lubricating oil is increased.
