Accumulator and compressor

Abstract

The invention provides an accumulator and a compressor. The accumulator comprises a shell, a plugging structure and a muffler chamber. The shell is provided with a containing cavity. The bottom of thecontaining cavity is an oil return area. The bottom of the shell is provided with an oil return port and an air supply port. The oil return port communicates with the oil return area. The plugging structure is arranged in the oil return area. At least a part of the plugging structure is movably arranged to avoid or plug the oil return port. The muffler chamber is arranged in the containing cavity. The muffler chamber is provided with a muffler cavity, an air inlet and an air outlet. The air inlet and the air outlet communicate with the muffler cavity, wherein flow cross-sectional area of themuffler cavity is larger than the area of the air inlet and the area of the air outlet. The air outlet communicates with the air inlet. Through the cooperation of the plugging structure and the oil return port, the oil return capacity of the accumulator is improved. The muffler chamber reduces the flow rate of gaseous refrigerants and the collision between the gaseous refrigerants, reduces the airflow excitation vibration of the refrigerants, and thereby reduces the noise and vibration of the accumulator.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a liquid accumulator and a compressor. Background technique [0002] The liquid receiver in the compressor is assembled on the suction hole of the pump body. When the volume of the suction cavity of the pump body increases to inhale, the gaseous refrigerant enters the cavity of the liquid storage device, and enters the suction cavity after being filtered by the filter. . When the refrigerant contains lubricating oil and liquid refrigerant, the lubricating oil and liquid refrigerant are continuously deposited into the storage liquid due to the cooperation of the straight pipe and the filter assembly, as well as the flow inertia and gravity of the lubricating oil and liquid refrigerant. the bottom of the device. [0003] The accumulated liquid refrigerant vaporizes as the working conditions of the refrigeration cycle change or absorbs heat from the environment, thus starting ...

AI Technical Summary

Problems solved by technology

However, when the lubricating oil in the existing liquid reservoir returns to the pump body, the oil return is not complete and the oil is not returned in time, and a large amount of lubricating oil is often stored at the bottom of the liquid reservoir, which leads to oil shortage in the pump body components, resulting in a lubricating state. deterioration

In addition, when the compressor is running, the accumulator will generate a lot of noise and vibration, reducing the overall performance of the compressor
