Embodiment Construction
[0035] Such as Figure 2-6.3 , the present invention provides a compressor exhaust structure, which includes:
[0036] Cylinder 1, roller 2 and first flange 3, the cylinder 1 includes a cylinder chamber 10, the roller 2 is arranged in the cylinder chamber 10, and the first flange 3 is arranged in the cylinder chamber 1 On the axial end face, and the first flange 3 is provided with a first exhaust hole 31, and the cylinder 1 is provided with a suction port 11, and the setting position of the first exhaust hole 31 is such that in the In the projection plane of the axial end surface of the cylinder 1 , the first exhaust hole 31 is completely located inside the cylinder chamber 1 .
[0037] In the present invention, the position of the first exhaust hole opened on the first flange is set so that in the projection plane of the axial end surface of the cylinder, the first exhaust hole is completely located inside the cylinder cavity, After the improvement of the exhaust hole of th...

The exhaust structure of the compressor comprises an air cylinder, a roller and a first flange, the air cylinder comprises an air cylinder cavity, the roller is arranged in the air cylinder cavity, the first flange is arranged on the axial end face of the air cylinder, and a first exhaust hole is formed in the first flange; the air cylinder is provided with an air suction port, the arrangement position of the first exhaust hole enables the first exhaust hole to be located in the projection plane of the axial end face of the air cylinder, and the first exhaust hole is completely located in the air cylinder cavity. According to the invention, the air suction cavity and the compression cavity can be prevented from communicating through the exhaust hole; meanwhile, refrigerants in the exhaust holes are not communicated with the air suction cavity, and the amount of refrigerants, flowing back to the air suction hole through the air suction cavity, in the first exhaust holes is reduced; therefore, the energy efficiency of the compressor is greatly improved.
Description
technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor exhaust structure and the compressor. Background technique [0002] In the existing rotary compressor, generally, the exhaust hole is arranged on the end cover, and the crescent groove is arranged on the cylinder. Some of them are inside the inner circle of the cylinder, and some are outside the inner circle of the cylinder; [0003] In each working cycle of the compressor, when the roller passes through the exhaust hole, the suction chamber and the compression chamber of the compressor will communicate through the exhaust hole. At this time, the residual refrigerant in the compression chamber will pass through the suction chamber and the suction chamber. The air hole is connected, causing backflow to affect the energy efficiency of the compressor. At the same time, the residual refrigerant in the exhaust hole and the crescent groove will also flow back into the...
