Problems solved by technology

[0002] In the related art, the rotary compressor generally has a suction channel from the main bearing, and the low-pressure gas is sucked into the cylinder suction chamber from the main bearing suction channel. The compressor with this suction structure needs to divide the high and low pressure chambers because the main bearing needs to be separated. However, due to the existence of high and low pressure, the main bearing is deformed, which affects the reliability of the compressor.

Abstract

The invention discloses a compressor. The compressor comprises a shell, a high pressure and low pressure separation plate and a first air cylinder, wherein an inner cavity is defined in the shell; the high pressure and low pressure separation plate is arranged in the shell and used for dividing the inner cavity into a high pressure cavity and a low pressure cavity; the first air cylinder is located in the high pressure cavity; the high pressure and low pressure separation plate is provided with a first air suction channel which communicates with the low pressure cavity and penetrates through the high pressure and low pressure separation plate; and the first air cylinder is provided with a second air suction channel, and the first air suction channel is connected with the second air suction channel. According to the compressor, the high pressure and low pressure separation plate is located between the high pressure cavity and the low pressure cavity to bear the pressure difference, so that the pressure difference borne by other components inside the compressor is reduced, pressure deformation of the former components can be reduced, and operation reliability of the compressor can be improved. In addition, the first air cylinder can suck refrigerants from the low pressure cavity through the first air suction channel and the second air suction channel, and thus stability of air intake in the first air cylinder can be ensured.

Description

technical field [0001] The present invention relates to a compressor. Background technique [0002] In the related art, the rotary compressor generally sets up the suction channel from the main bearing, and sucks the low-pressure gas into the cylinder suction chamber from the main bearing suction channel. The compressor with this suction structure needs to divide the high and low pressure chambers because the main bearing needs to be divided. However, due to the existence of high and low pressure, the main bearing is deformed, which affects the reliability of the compressor. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a compressor, which has good structural reliability and meets air intake requirements. [0004] According to the compressor of the present invention, it includes: a shell, which defines an inner cavity; a ...
