Sliding vane compressor and household appliance

Abstract

The invention relates to a sliding vane compressor and a household appliance equipped with the sliding vane compressor. The sliding vane compressor comprises a motor assembly, a pump assembly and a shell assembly, wherein the motor assembly and the pump assembly are sequentially arranged in the shell assembly in the horizontal direction; an exhaust pipe is arranged on the shell assembly; the inner cavity of the shell assembly is divided by the motor assembly and the pump assembly into a plurality of cavity chambers, namely a first cavity chamber positioned on one side of the pump assembly, a second cavity chamber positioned between the pump assembly and the motor assembly, and a third cavity chamber positioned on one side of the motor assembly; the exhaust pipe is arranged on the shell assembly corresponding to the third cavity chamber; and the bottoms of the three cavity chambers communicate with one another. The sliding vane compressor provided by the invention adopts a pump-motor integrated structure, and the oil and gas paths of the complete machine are integrally designed, so that sufficient back pressure of sliding vanes can be guaranteed, and the sliding vanes can be opened quickly.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a vane compressor and a household appliance equipped with the compressor. Background technique [0002] The vane compressor is mainly composed of cylinder, rotor, vane and cylinder head. The air cylinder is provided with an air suction port and an air discharge port, and a rotor provided with a longitudinal groove is arranged eccentrically in the cylinder, and a sliding plate capable of longitudinally sliding is arranged in the groove. When the rotor rotates, the sliding vane is thrown out of the groove under the action of centrifugal force, and the end is close to the inner wall of the cylinder. The crescent-shaped space formed by the inner wall of the cylinder and the outer surface of the rotor is divided into several small chambers by the sliding vane, called primitives. volume. When the rotor rotates once, the volume of the element changes from the smallest to the large...

AI Technical Summary

Problems solved by technology

[0005] 1) The friction power consumption of the sliding vane compressor is large

The pump body of the sliding vane compressor is generally composed of multiple sliding vanes. The compressor with this structure has more friction pairs, and the friction power consumption is larger than that of the rotary compressor. Machine power consumption is low;

[0006] 2) The oil and gas circuit design of the vane compressor is complex
