Compressor partition plate structure, compressor and air conditioner

Abstract

The invention provides a compressor partition plate structure, a compressor and an air conditioner. The compressor partition plate structure comprises a first partition plate and a second partition plate. The first partition plate comprises a first through hole through which the eccentric portion of a crank shaft can penetrate, the second partition plate comprises a second through hole through which the eccentric portion of the crank shaft can penetrate, and the first partition plate and the second partition plate can be overlaid and connected. When the first partition plate and the second partition plate are overlaid and connected, the first through hole and the second through hole are partially overlaid, a hole area through which the shaft diameter diameter portion of the crank shaft canpenetrate is formed in the overlaid portion, the non-overlaid portion can be sealed, and the hole area formed in the overlaid portion is larger than the shaft diameter size of the crank shaft and smaller than the diameter of the eccentric portion of the crank shaft. The inner hole size of the partition plates can be reduced, the sealing distance of the inner holes of the partition plates is increased, and the sealing effect is improved. Meanwhile, limiting of the inner hole diameter of the partition plates is avoided, the largest eccentric magnitude of the eccentric portion of the crank shaftcan be further increased, and the largest discharge of a pump body of the compressor can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a compressor diaphragm structure, a compressor and an air conditioner. Background technique [0002] In order to prevent gas blow-by between the upper and lower cylinders, the existing double-cylinder compressor uses a partition for sealing. When the inner hole of the partition is smaller, the sealing distance provided by the partition can be made larger. In this way, the eccentricity of the eccentric circle of the compressor crankshaft can also be made larger. Under the condition of the same cylinder height and bore, the greater the eccentricity of the compressor, the greater the achievable displacement of the compressor. [0003] However, in the prior art, in order to ensure that the partition can be inserted into the eccentric circle. It is required that the size of the inner hole of the separator must be larger than the outer diameter of the eccentric circle...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the relatively large inner hole size of the diaphragm of the compressor in the prior art, resulting in a small sealing distance of the diaphragm , can not guarantee the sealing effect of the compressor should be defective, so as to provide a compressor diaphragm structure, compressor and air conditioner
