Compressor and air conditioner

Abstract

The invention provides a compressor and an air conditioner. The compressor comprises a compressor shell, a stator iron core and a gas-liquid separator; the stator iron core is connected into the compressor shell, and a concave part is formed in the outer circumferential wall of the stator iron core; a projection plane is perpendicular to the central axis of the compressor shell; the outer peripheral wall of the compressor shell is projected on the projection plane to form a first circle by taking point A as the circle center, the outer peripheral wall of the gas-liquid separator is projected on the projection plane to form a second circle by taking point B as the circle center, and a third circle is formed by taking the point B as the circle center and taking straight line AB as the radius; and the third circle is provided with a tangent line by taking the point A as a tangent point, and the tangent line passes through the concave part. According to the compressor and the air conditioner, the vibration noise of the compressor can be greatly reduced, the swing of the gas-liquid separator is reduced, so that the noise level of the whole machine of the air conditioner is reduced, andthe comfort of the air conditioner is improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a compressor and an air conditioner. Background technique [0002] In existing compressors, the motor stator 2' and the compressor housing 1' are generally set as an interference fit, and the motor stator is fixed inside the compressor housing 1' through a shrink fit. Due to the interaction between the stator and rotor magnetic fields of the motor during the operation of the compressor, a radial excitation force is generated on the stator teeth (such as figure 1 Indicated by the solid line arrow f in ), so that the motor stator generates radial vibration and transmits noise through the compressor casing 1'. In the air conditioning system, the noise in the frequency band within 1000 Hz is the most prominent, and the gas-liquid separator 3 'The vibration noise generated by the excited mode is one of the main reasons for the abnormal noise of the compressor wit...

Problems solved by technology

Aiming at the problem of compressor vibration and noise caused by the radial excitation force of the stator, the patent document with the publication number CN101646869A uses a plurality of welded parts on the stator side at different positions in the axial direction of the stator to conduct point joints with the housing, replacing the traditional stator housing The interference shrink fit can reduce the vibration and noise of the compressor, but this technical solution is quite different from the traditional technical process, and the production process needs to be greatly changed, and the process of fixing the stator by multi-point welding seriously reduces the compressor. work efficiency
