Compressor and air conditioner

Abstract

The invention provides a compressor, comprising a housing, and a rotor, a stator, and a crankshaft in the housing. The lower end of the crankshaft is provided with a first magnet. The bottom cover of the housing is provided with a second magnet corresponding to the first magnet. The magnetic pole polarity of opposite magnetic pole surfaces of the first magnet and the second magnet is opposite. The invention also relates to an air conditioner. The compressor and the air conditioner are provided with the first magnets on the lower ends of the crankshafts, and the bottom covers of the housings are provided with second magnets. The magnetic pole polarity of opposite magnetic pole surfaces of the first magnet and the second magnet is opposite. Thus, strong downward acting forces are applied on a pump rotor assembly, and stable operation of the pump structure of the compressor is ensured. Up-down displacement would not occur, and mechanical impact noise is effectively prevented.

Description

technical field [0001] The invention relates to the refrigeration field, in particular to a compressor and an air conditioner. Background technique [0002] Such as Figure 1 to Figure 3 As shown, in the prior art compressor, when the compressor is exhausted, the pump body rotor assembly is subject to a large upward gas impact force, because the gravity of the pump body rotor assembly itself is not enough to overcome the gas impact force. Therefore, a height difference h is set between the stator 3 and the rotor 2 of the compressor motor, so that the height of the rotor 2 is higher than that of the stator 3 . The height difference is used to generate downward magnetic pull, coupled with the pump body gravity, to make it greater than the maximum gas impact force during exhaust, so as to ensure that the pump body rotor assembly will not move axially and produce harsh impact noise. If the height difference is not set properly, there will be the following two problems: (1) The ...

Problems solved by technology

If the height difference is not set properly, there will be the following two problems: (1) The setting of the height difference between the stator and the rotor is too small, which will cause the pump body components to move axially and generate strong impact noise; (2) The height difference between the stator and the rotor If the setting is too large, the efficiency of the motor will be reduced, and the maximum efficiency of the motor cannot be fully utilized, thereby reducing the performance of the compressor.
