Problems solved by technology

It is used to solve the problems existing in the prior art: setting up injection channels on the fixed scroll, due to the limitation of the size and structure of the fixed scroll, the design of the channel is very complicated, the opening of the channel cannot be optimal, and the ratio of the area to the length of the channel is also low. Very large, not conducive to processing and other issues

Abstract

The invention relates to a scroll compressor with an injection channel, in particular to an injection channel and noise reduction structure of the scroll compressor, which belongs to the technical field of scroll compressors. A motor stator is fixedly installed at the lower part in a housing, a motor rotor is installed in the motor stator, and the motor rotor is installed at the bottom of a crank shaft; an upper support and a movable scroll are installed on the crank shaft, a cross ring is installed between the movable scroll and the upper support, and a stationary scroll is fixed on the upper support; the stationary scroll is fitted with the movable scroll to form a plurality of compressed cavities, and an upper cover covers on the housing. The scroll compressor with the injection channel has the characteristicsis characterized in that a valve plate is installed on the stationary scroll through a bolt hole on the valve plate and a screw, the valve plate is provided with a main ejection channel and an ejection channel communicated with the main ejection channel, a through channel which is communicated with an ejection port on the stationary scroll is arranged at the lower part of the ejection channel, a groove is arranged at the lower part of the valve plate and encloses the stationary scroll to form a space, and an ejection pipe is installed on the main ejection channel.

Description

technical field [0001] The scroll compressor with injection channels of the present invention relates to the field of scroll compressors, in particular to the injection channels and noise reduction structures of scroll compressors. Background technique [0002] At present, the existing scroll compressor includes a fixed scroll with spiral scroll teeth, and a movable scroll with spiral scroll teeth matched with the fixed scroll, between the movable scroll and the upper support Movement, respectively cooperate with the movable and fixed scrolls and limit them to the cross rings that can only move in relative translation. Through the mutual cooperation of the movable scroll and the fixed scroll, multiple compression chambers with variable volumes are formed. The motor drives the crankshaft to drive the movable scroll. The rotary revolves along its orbit to complete the suction, compression and discharge of gas. In order to inject refrigerant into the compression chamber under ...
