Abstract

The invention provides a compressor with a double-supporting structure and an electric appliance. The compressor comprises a shell, a pump body arranged in the shell and a crankshaft, one end of the crankshaft is rotatably connected with a first supporting structure, and the other end of the crankshaft is rotatably connected with a second supporting structure. According to the compressor with the double-supporting structure and the electric appliance, the deflection deformation of the end parts of the crankshaft is improved, the rotor swinging amount in the operation process of the compressor is reduced, and the end surface position of a rotor and a stator are prevented from being scratched and damaged; the gap uniformity between the stator and the rotor is improved, and electromagnetic noise caused by the non-uniform gap between the stator and the rotor is avoided; and the position of a leading-out wire is bound, and the leading-out wire is prevented from being scratched by the rotor due to contact with the rotor.

Description

technical field [0001] The invention belongs to the technical field of compressor manufacturing, and more specifically relates to a supporting structure of a compressor, a compressor and an electrical appliance. Background technique [0002] Conventional rotary compressors (such as figure 1 As shown), the following problems often occur during operation: 1. Due to the existing rotary compressor, one end of the crankshaft is supported, while the other end of the crankshaft (connected to the rotor) is not supported, resulting in high-speed In the rotating state, the other end of the crankshaft has a large deflection deformation, that is, the rotor swings a lot, which makes the abnormal phenomenon of scraping the rotor end surface with the stator; 2. The position of the lead wire is free and unrestricted, so it is easy to bend The rotor, which causes the lead wire to contact the rotor and be scratched by the rotor, resulting in poor pressure resistance; 3. The gap between the s...
