Problems solved by technology
[0002] At present, the driving motor of the inverter air conditioner compressor is a single-phase asynchronous motor or a DC motor. Because a motor has a slip loss, the existence of the DC motor brush makes its failure rate high and its service life low, so asynchronous motors and DC motors are not air conditioners. The ideal component of the compressor, the permanent magnet brushless DC motor is a new generation of high-performance drive motor, but the existing permanent magnet motor may produce irreversible demagnetization during severe mechanical vibration, which will reduce the performance of the motor and even make it unusable. This will seriously affect the normal use of the air conditioner, and now most of the air-conditioning after refrigeration is not processed and is directly discharged. There are some substances left in such air-conditioning, which will make the discharged air-conditioning smell bad

The invention discloses an air conditioner with a permanent magnet motor. A compression mechanism compresses to generate high pressure and low pressure gas through the transmission of a power mechanism, meanwhile, the vibration of the permanent magnet motor on the power mechanism is weakened by a vibration reduction mechanism to ensure that the permanent magnet motor does not generate irreversibledemagnetization due to excessive vibration and enables motor performance to be degraded, the mechanical operation of the power mechanism enables a negative ion generator on a cold air purification mechanism to work to purify refrigerated gas, and the refrigerated gas is discharged indoors to ensure the degree of purification of cool air and prevent the emission of odor.
