Description

Technical Field

[0001] The present application belongs to the technical field of air conditioners, and in particular relates to a compressor and an air conditioner having the same. Background Art

[0002] At present, the existing compressors are controlled by motors and are divided into two types: fixed frequency and variable frequency. The exhaust valve of the compressor basically adopts a fixed limiter structure to limit the valve lift. For fixed frequency compressors, stable compressor performance can be obtained by setting a reasonable valve lift through the limiter.

[0003] However, for variable frequency compressors, using a limiter to fix the valve lift will inevitably sacrifice certain performance. As the core component of the compressor, the exhaust valve plate has a structural integrity that is the basic guarantee for the normal operation of the compressor. When the compressor is exhausted, the exhaust valve plate opens and collides with the limiter at high speed. The reciprocating impact between the valve plate and the limiter will not only cause fatigue fracture of the exhaust valve plate and the limiter, but also increase the noise of the compressor; and the sealing of the exhaust valve plate to the exhaust port determines the leakage of the compressor during exhaust. The traditional compressor exhaust valve plate is only conducive to the height difference between the head and the tail of the valve plate during installation to reduce the leakage of gas from the exhaust port. First, the processing accuracy of the flange exhaust port is very high, and the height difference needs to be controlled at 0.01-0.05mm, which is difficult to process. In addition, there will still be a certain degree of non-centrality when the valve plate is actually installed, which affects the sealing of the valve plate and the exhaust port. Secondly, the head of the valve plate is not completely parallel to the exhaust port, but there is a small inclination angle, which seriously reduces the sealing of the exhaust port. Therefore, the existing compressor exhaust valve plate not only seriously affects the reliability and noise of the valve plate, but also has a great impact on the leakage problem and performance level of the compressor.

[0004] Therefore, how to provide a compressor and an air conditioner having the same that can ensure the long-term reliability of the valve plate, significantly reduce the noise level of the equipment, and prevent gas leakage has become an urgent problem that technicians in this field need to solve.
