Abstract

The invention provides a compressor and a refrigeration device. The compressor comprises a shell, a pump body assembly which is arranged in the shell and comprises a crankshaft and an upper bearing,and a motor assembly which is arranged in the shell configured to be suitable for driving the pump body assembly. The motor assembly comprises a stator assembly which is fixed on the upper bearing, and a rotor assembly which is connected with the crankshaft. The rotor assembly drives the crankshaft to perform rotary compression, and the rotor assembly is arranged in the axial direction of the stator assembly. According to the compressor provided by the invention, the stator assembly is directly fixed on the upper bearing, so that the stress of the stator assembly is reduced; the electromagnetic noise is reduced, and the performance of the motor assembly is improved; the performance of the compressor is improved; the rotor assembly is arranged in the axial direction of the stator assembly,and the rotor assembly and the stator assembly are designed to be flat, so that the height of the motor assembly is low; and the flat stator assembly and the flat rotor assembly are similar to plates,so that the miniaturization design of products is realized.

Description

technical field [0001] The present invention relates to the technical field of compressors, in particular to a compressor and a refrigeration device. Background technique [0002] Such as figure 1 As shown, the basic structure of the existing compressor 100' is generally that the motor is on the top, and the pump body is on the bottom, and is located in the closed casing 110'. The motor includes a rotor assembly 140' and a stator assembly 130' which fit radially inside and outside. The stator assembly 130' is fixed in the casing by shrink fit, and the rotor assembly 140' is connected to the crankshaft 121' by shrink fit, thereby driving the pump body to compress. The height of the motor in which the rotor assembly 140' and the stator assembly 130' are radially fitted inside and outside is relatively high, and upper and lower counterweight balance blocks need to be provided, so that the height of the compressor 100' is large, the center of gravity is high, and it is not cond...
