Abstract

The invention provides a compressor and an air conditioner including the compressor, and relates to the technical field of refrigerating equipment. The compressor comprises a shell, a crankshaft and arotor. A containing cavity is formed in the shell, and the crankshaft and the rotor are arranged in the containing cavity. The crankshaft comprises a first shaft segment and a second shaft segment, the first shaft segment and the rotor are fixed, and a first magnetic part is arranged on the end face of the second shaft segment. A second magnetic part is arranged at the position, opposite to the first magnetic part, of the inner wall face of the shell. The magnetism of the second magnetic part is opposite to that of the first magnetic part. The crankshaft is sawn through attraction force between the second magnetic part and the first magnetic part, and meanwhile the crankshaft can transmit the attraction force to the rotor; and therefore upward jumping of the crankshaft and the rotor is reduced, the noise problem generated due to the fact that the crankshaft collides with other components of the compressor is solved, stability of the crankshaft is improved, and then operation stabilityof the compressor is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular, to a compressor and an air conditioner including the compressor. Background technique [0002] In recent years, rotary compressors have developed rapidly, but there are problems such as wear of internal parts of the compressor and abnormal noise during use. During the operation of the rotary compressor, the main forces on the crankshaft and rotor are gravity, friction and gas force respectively. When the compressor rotates at a high speed, the internal gas pressure pulsation increases, and the gas force on the crankshaft and rotor is greater than gravity and gas force. When the sum of friction forces is applied, the crankshaft and rotor will jump upwards, resulting in collision noise and wear of parts. Contents of the invention [0003] In order to solve the technical problem in the prior art that the crankshaft and the rotor move and cause noise due to unbalance...
