Abstract

The invention provides a compressor exhaust structure, a compressor and an air conditioner. The compressor exhaust structure comprises an upper flange, a crankshaft and an upper flange shaft hole. Theexhaust port is formed in the upper flange and communicated with a compression cavity of a compressor cylinder. High-pressure gas in the compression cavity is exhausted into the exhaust port. An oilgas groove is formed in the inner wall of the upper flange shaft hole and / or the outer wall of a crankshaft. The exhaust port is communicated with the oil gas groove. High-pressure gas enters the upper flange through the exhaust port and then flows through the oil gas groove to be exhausted, and oil mist in the high-pressure gas lubricates the shaft hole of the upper flange. According to the compressor exhaust structure, the problem of insufficient lubrication of the bearing section of the upper flange is solved; the upper flange is lubricated by means of lubricating oil dissolved in the compressor exhaust; supply of the lubricating oil is continuous, and particularly, the lubricating effect of the upper flange under a low-frequency working condition is better than that of the prior art; and meanwhile, a silencing cavity is completely sealed by a cover body, so that a more effective silencing effect can be achieved.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a compressor exhaust structure, a compressor and an air conditioner. Background technique [0002] The lubrication between the upper flange and the crankshaft of the existing rotary compressor depends entirely on the upward pumping of oil by the crankshaft, and then the oil guide groove of the upper flange guides oil upward due to the rotation of the crankshaft. However, this method has disadvantages, that is, the refrigerant oil cannot be pumped to the upper flange when the compressor is running at low frequency, resulting in the failure of the upper flange to be lubricated, or too little lubricating oil pumped to the upper flange, and insufficient lubrication of the upper flange, resulting in Upper flange is worn. Contents of the invention [0003] Therefore, the technical problem to be solved by the present invention is insufficient oil pumping and insuffici...
