Abstract

The invention provides an exhaust structure and a compressor. The exhaust structure comprises an air cylinder, a bearing and a valve plate, wherein the air cylinder is provided with an air cylinder exhaust cavity and a crescent groove communicating with the air cylinder exhaust cavity; a bearing exhaust hole is formed in the bearing, and a first inlet of the bearing exhaust hole communicates with the crescent groove; the valve plate is connected with the bearing, and the valve plate is provided with a mounting position covering a first outlet of the bearing exhaust hole; the bearing exhaust hole comprises an exhaust hole body, and the center line of the exhaust hole body and the valve plate located at the mounting position are arranged in an inclined manner; and flow guide recess parts are arranged on the hole wall of the exhaust hole body. According to the exhaust structure provided by the invention, the problem that in the prior art, an exhaust structure of a compressor is large in exhaust resistance is solved.

Description

technical field [0001] The invention relates to the field of compressors, in particular to an exhaust structure and a compressor. Background technique [0002] With the continuous increase of the displacement of the rotary compressor, the number and size of the exhaust holes in the pump body increase, but the increase in the number and size of the exhaust holes in the pump body is limited by the structure of the compressor and the compressor valve baffle component reliability. When the displacement increases, the total cross-sectional area of ​​the exhaust hole can no longer match the displacement. Therefore, the performance of a large-displacement compressor is limited by the number and size of the exhaust holes in the pump body. As the displacement increases, the exhaust resistance increases significantly, resulting in a serious decline in compressor performance as the frequency increases. [0003] The shape of the bearing exhaust hole 21 of the bearing 20 in the prior a...
