Compressor upper cover and compressor

Abstract

The invention relates to a compressor and a compressor upper cover. The compressor upper cover comprises a top wall and side walls, the top wall and the side walls are connected in an intersecting mode and define an accommodating cavity, and a guide groove is formed in the inner surfaces, facing the accommodating cavity, of the side walls; wherein the guide groove is provided with a head section and a tail section which communicate with each other, and the head section is close to the top wall and is bent; and the tail section is far away from the top wall, and the tail section is obliquely arranged in the direction far away from the top wall in the direction parallel to the top wall. The bent guide groove is formed in the inner side of the compressor upper cover, so that gas flowing to the compressor upper cover is guided to flow along the guide groove in a bent mode, impact between gas flow and the compressor upper cover is relieved, and noise of the compressor is further reduced. Moreover, when the air flow flows from the head section to the tail section in the guide groove from top to bottom, oil liquid doped in the air flow can be retained on the inner wall of the guide groove, and finally the retained oil liquid flows out from the obliquely downward tail section, so that the oil liquid in the air flow can be separated and recycled, the oil spitting rate of the compressoris reduced, and reliable lubrication of the compressor is guaranteed.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a compressor upper cover and a compressor. Background technique [0002] The scroll compressor is a compressor with a compressible volume composed of a fixed involute scroll and an eccentric orbiting and translational involute moving scroll. The scroll compressor is composed of two double-function equation-shaped moving disks and static disks that mesh with each other. During the working process of suction, compression and exhaust, the static disk is fixed on the frame, and the movable disk is driven by the eccentric shaft and controlled by the anti-rotation mechanism, and rotates in a plane with a small radius around the center of the base circle of the static disk. The gas is sucked into the periphery of the static disc through the air filter element. With the rotation of the eccentric shaft, the gas is gradually compressed in several crescent-shaped compression chamb...
