Suction muffler, compressor, refrigerator

Abstract

The invention provides a suction muffler, a compressor, and a refrigerator, wherein the suction muffler includes a casing, the casing is configured with an air inlet and an exhaust port, and the inner cavity of the casing is provided with A baffle, the baffle divides the inner cavity into an upper cavity corresponding to the exhaust port and a lower cavity corresponding to the air inlet, and the baffle is configured with a The multiple through holes of the cavity also include multiple oil-gas separation covers, and the multiple oil-gas separation covers are respectively one-to-one covered on the multiple through holes and are located on the side of the partition facing the upper chamber. On the side, the oil-gas separation cover has a flow hole to pass through the upper chamber and the lower chamber. According to the suction muffler, compressor, and refrigerator of the present invention, the amount of oil carried by the suction of the cylinder can be reduced, and at the same time, the resistance of the suction air flow and the noise of suction can be reduced, so that the suction is more uniform and smooth.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a suction muffler, a compressor and a refrigerator. Background technique [0002] When the piston compressor is running at high frequency, the lubricating oil discharges a large amount of oil during the process of oiling the crankshaft; at the same time, a large amount of heat is generated inside the shell, which leads to an unfavorable state of high temperature inside the shell, especially the lubricating oil is easy to form oil mist It is easier to enter the suction muffler, which will lead to a large amount of oil in the suction, increase the compression power consumption of the compressor, reduce the performance of the compressor and the heat transfer efficiency of the system, and the airflow noise in the suction muffler will also affect the compression. How to reasonably arrange the baffles to reduce the suction resistance and noise has become an important ...
