Scroll plate assembly, scroll compressor and air conditioner

Abstract

The invention relates to the technical field of compressors, and provides a scroll plate assembly, a scroll compressor and an air conditioner. The scroll plate assembly comprises a static scroll plate, and an air inlet hole, an exhaust hole and an oil injection channel are formed in the static scroll plate. A movable scroll plate is meshed with the static scroll plate, a working chamber is formed between the movable scroll plate and the static scroll plate, an oil injection groove communicated with a back pressure chamber of the scroll compressor is formed in the movable scroll plate, and the movable scroll plate is configured to translate relative to the static scroll plate so as to compress a gas entering the working chamber. The oil injection channel is intermittently communicated with the oil injection groove and the working chamber, so that oil in the back pressure camber is intermittently injected into the working chamber under the action of the pressure difference between the back pressure chamber and the working chamber. According to the technical scheme, the gas in the working chamber can be effectively prevented from leaking to the back pressure chamber, so that the flow loss of the gas is reduced in the working process of the scroll plate assembly, and the scroll compressor is promoted to improve the energy efficiency.

Description

technical field

[0001] The present application relates to the technical field of compressors, in particular, to a scroll assembly, a scroll compressor and an air conditioner. Background technique

[0002] At present, the pressure of the back pressure chamber of the scroll compressor is an intermediate pressure, and the movable scroll is close to the static scroll under the pressure of the back pressure chamber. If the pressure of the back pressure chamber is too high, the movable scroll and the static scroll The friction loss of the disk bonding surface increases, and the power increases; if the pressure in the back pressure chamber is too small, the movable scroll cannot be smoothly attached to the static scroll, which will easily cause the movable scroll to overturn and cause air leakage , resulting in a decrease in the working capacity of the scroll compressor. In the prior art, by setting a back pressure hole in the working chamber, the back pressure hole communicates w...
