Air suction muffler and compressor provided with same

Abstract

The invention discloses an air suction muffler and a compressor provided with the same. The air suction muffler comprises a casing and an oil baffle element, wherein the casing is provided with an air suction port and an air exhaust port, and an airflow channel communicated with the air suction port and the air exhaust port is formed in the casing; the oil baffle element is arranged on the casing, bulges out of the outer wall surface of the casing and extends outwards, and at least part of the oil baffle element is located right above the air suction port. According to the air suction muffler disclosed by the embodiment, refrigerator oil is not easily carried into the air suction muffler by a refrigerant from the air suction port, so that the quantity of the refrigerator oil flowing into a compression chamber along with the refrigerant is reduced greatly, the oil puff quantity of the compressor is reduced, and the safe reliability is improved.

Description

technical field [0001] The present invention relates to the technical field of compressors, more specifically, to a suction muffler and a compressor with the suction muffler. Background technique [0002] The fully enclosed refrigerator compressor has an eccentric hole on the crankshaft. The motor drives the crankshaft to rotate, so that the refrigerating machine oil at the bottom of the compressor shell generates an upward centrifugal force, and then is thrown to the moving parts through the eccentric shaft. During the lubrication process, only a small part of the refrigerating machine oil enters the cylinder for lubrication, and most of the refrigerating machine oil splashes around the pump body and the inner wall of the casing, and then flows back to the bottom of the compressor under the action of gravity. Refrigerator oil that returns to the bottom of the compressor can be cycled back and forth again. [0003] In the related art, the oil discharge volume of the compres...

AI Technical Summary

Problems solved by technology

[0004] 1. The large amount of oil discharged by the compressor may lead to increased viscosity of the recovered oil when the refrigerating machine oil in the compressor passes through the low-temperature part after being discharged, resulting in insufficient lubrication of the refrigerating machine oil in the compressor and increased wear, affecting the life and reliability of the compressor sex

[0005] 2. The large amount of oil discharged by the compressor may cause the refrigerating machine oil in the compressor to be partially decomposed in the high-temperature part, and the degraded product of the discharged oil will form carbon deposits and accumulate in the valve part, causing the gas to flow back, and the temperature of the compression part will rise, which will further promote the accumulation. Accelerated formation of carbon

[0006] 3. The large amount of oil discharged by the compressor may cause corrosive acid to be generated when the refrigeration oil in the compressor deteriorates, causing corrosion of internal parts and causing the motor to burn out
