Oil absorption assembly, compressor comprising oil absorption assembly and electric appliance

Abstract

The invention discloses an oil absorption assembly, a compressor comprising the oil absorption assembly and an electric appliance. The oil absorption assembly comprises a deformable oil pipe assembly,the oil pipe assembly is provided with a channel for allowing lubricating oil to flow, a first end of the channel extends into an oil tank of the compressor, a second end of the channel is connectedwith a pump body assembly of the compressor, and the density of the oil pipe assembly is smaller than that of the liquid refrigerant, so that the first end of the channel is located at the liquid level position of the liquid refrigerant or above the liquid refrigerant liquid level. According to the arrangement, the first end of the channel can be changed along with the height of the liquid surfaceof the liquid refrigerant and is in contact with the lubricating oil, lubricating oil is sucked to the position of the pump body assembly of the compressor through the channel, lubricating oil is provided for working of the pump body assembly, and the problems of abnormal abrasion and poor sealing of the pump body assembly are avoided.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to an oil absorbing assembly, a compressor including the oil absorbing assembly, and an electrical appliance. Background technique [0002] For horizontal compressors, during operation, please refer to figure 1 Generally, lubricating oil 3 is provided to the pump body assembly of the compressor through the oil suction pipe assembly 1 . The oil suction pipe assembly 1 includes a copper oil suction pipe, one end of the oil suction pipe is sleeved on the shaft diameter of the lower flange, and the other end extends into the oil pool at the lower end of the compressor cavity. [0003] However, after the compressor stops, due to the migration of the refrigerant in the system, most of the refrigerant will move back into the internal cavity of the compressor and liquefy into a liquid, such as figure 2 shown. The density of liquid refrigerant 2 is generally 1.05g / cm 3 , while the d...
