Embodiment Construction
[0048] Such as Figure 1-9 , the present invention provides a compressor exhaust structure, which includes:
[0049]Cylinder 1, crankshaft, roller 2 and first flange 3, described cylinder 1 comprises cylinder chamber 10, described roller 2 is arranged in described cylinder chamber 10, and described first flange 3 is arranged in described cylinder 1, 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 position of the first exhaust hole 31 is such that when When the crankshaft rotates to a preset crank angle range (that is, the crankshaft rotates to a certain angle range), the first exhaust hole can be completely closed by the roller (preferably when the air suction hole is opened).
[0050] In the present invention, the position of the first exhaust hole opened on the first flange is set so that the first exhaust hole is completely closed by the movement of the roller (preferably when the suction port ...

The exhaust structure of the compressor comprises an air cylinder, a crankshaft, 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, and due to the arrangement position of the first exhaust hole, when the crankshaft rotates to a preset crankshaft rotation angle range, the first exhaust hole can be completely closed by the roller. According to the invention, the first exhaust hole is opened only after the suction is closed, so that the residual high-pressure refrigerant in the first exhaust hole is prevented from communicating with the suction hole, the suction is not influenced, the residual refrigerant in the exhaust of the cylinder is effectively prevented from flowing back to the suction hole, the normal suction of the compressor is ensured, and the energy efficiency of the compressor is 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 existing compressors, in each working cycle, the refrigerant in the cylinder and the exhaust hole on the flange cannot be discharged from the cylinder, and will remain inside the pump body. Moreover, when the rollers turn to a certain angle, the exhaust hole will be in contact with the cylinder. The suction hole is connected, causing the refrigerant in the exhaust hole in the suction cavity to flow back to the suction hole, such as Figures 1a-1d shown. It affects the suction of the compressor, and makes this part of the high-pressure refrigerant released out of the cylinder, repeated compression, and consumes extra power of the compressor, which is not good for the energy efficiency of the compressor. [0003] Since the compressor in the prior art has technical problems such as the return of...
