Problems solved by technology

However, due to the winding gap in the stator of the concentrated winding motor, the compressor has the following problems: the high-pressure gas compressed by the pump body assembly is discharged through the muffler, and then flows through the rotor flow hole to the upper cavity of the casing and then discharged out of the compressor
On the one hand, it leads to the high oil discharge rate of the compressor, which reduces the energy efficiency of the compressor; on the other hand, the oil level in the oil pool of the compressor is too low, and the pump oil is insufficient, which makes the lubrication of the pump body components insufficient, resulting in the reliability of the compressor. sex decline

Abstract

The invention discloses a silencer, a compressor and an air conditioner. The silencer comprises a silencing assembly and an oil baffle assembly, the oil baffle assembly is arranged on the silencing assembly, and the oil baffle assembly divides a lower cavity of the compressor into a first cavity and a second cavity. When the compressor operates, refrigerant oil is pumped out by a compressor oil guide part and enters the first cavity, under the action of high-pressure gas exhausted by the silencing assembly, the refrigerant oil in the first cavity can enter the upper cavity along with the high-pressure gas through a rotor circulation hole, due to the effect of gravity, the refrigerant oil in the upper cavity flows into the second cavity from a stator winding gap, and at the moment, most of the high-pressure gas is located in the first cavity under the action of the oil baffle assembly so that the refrigerant oil in the second cavity cannot be influenced by the high-pressure gas and flows into an oil pool of the compressor under the action of gravity; and therefore, the problem that a large amount of refrigerant oil is gathered between the upper cavity and the lower cavity can be solved, and lubrication and the oil spitting rate of the compressor are guaranteed.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a muffler, a compressor and an air conditioner. Background technique [0002] With the upgrading of air-conditioning energy efficiency systems, concentrated coil motors are more and more widely used in rolling rotor refrigeration compressors due to their high energy efficiency. However, due to the winding gap in the stator of the concentrated winding motor, the compressor has the following problems: the high-pressure gas compressed by the pump body assembly is discharged through the muffler, and then passes through the rotor flow hole to the upper cavity of the casing and then is discharged from the compressor. However, the refrigerated oil in the compressor will also follow the high-pressure gas to the upper chamber of the housing, and then flow back to the lower chamber of the housing through the gap of the stator wire package. . Therefore, a large amount of refrigerating...
