Oil baffle cap structure, compressor and air conditioner

Abstract

The invention provides an oil baffle cap structure, a compressor and an air conditioner, the oil baffle cap structure comprises an umbrella cover and a plurality of balancing weights arranged on the umbrella cover, the umbrella cover has a completely folded state corresponding to a first rotating speed and a completely unfolded state corresponding to a second rotating speed, and in the process that the rotating speed of the umbrella cover is increased from the first rotating speed to the second rotating speed, the balancing weights are arranged on the umbrella cover. In the process that the rotating speed of the umbrella cover is reduced from the second rotating speed to the first rotating speed, the umbrella cover is gradually unfolded from the completely-folded state to the completely-unfolded state under the centrifugal force effect of the balancing weight, and in the process that the rotating speed of the umbrella cover is reduced from the second rotating speed to the first rotating speed, the umbrella cover is gradually folded from the completely-unfolded state to the completely-folded state under the self-weight effect of the balancing weight; the umbrella cover is in a completely stored state, so that the refrigerant flows more smoothly, and the low-frequency energy efficiency of the system is improved; the umbrella cover is in a semi-open state, the oil content in a refrigerant is reduced, the cold-heat exchange efficiency of the system is improved, and the medium-frequency energy efficiency is improved; the umbrella cover is in a completely-opened state, the oil content of a flowing refrigerant is reduced to the maximum extent, and the high-frequency energy efficiency of the system is improved.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to an oil blocking cap structure, a compressor and an air conditioner. Background technique [0002] With the implementation of the new national standard for air conditioners, the requirements for the energy efficiency level of air conditioners are getting higher and higher. As the core power component of the air conditioner, the energy efficiency of the compressor directly affects the energy efficiency level of the air conditioner. During the operation of the compressor, the smoothness of the refrigerant flow and the oil content of the system will have a great impact on the energy efficiency of the system. [0003] When the compressor is running at low speed, we hope that the refrigerant flow in it will be smoother, so that the exchange of cold and heat in the system will be smoother, thereby improving the low-frequency energy efficiency; but at this time, the oil ...
