Electric commutator

Abstract

The invention relates to the field of air conditioner accessories, in particular to an electric commutator. The electric commutator comprises a valve body, a valve element and a driving motor, wherein the valve element is rotationally arranged in the valve body; the driving motor is arranged outside the valve body, is fixedly connected with the valve element and can drive the valve element to rotate; a first vent hole, a second vent hole, a third vent hole and a fourth vent hole which are communicated with an inner wall respectively are formed in an outer wall of the valve body; the first vent hole is coaxial with the third vent hole; the second vent hole is coaxial with the fourth vent hole; the axis of the first vent hole is perpendicular to that of the second vent hole; the valve element is hermetically connected with the valve body; a first communication hole and a second communication hole are formed in the valve element; two ends of the first communication hole are communicated with the first vent hole and the second vent hole respectively; two ends of the second communication hole are communicated with the third vent hole and the fourth vent hole respectively. The electric commutator is simple in structure, easy to manufacture and convenient to operate, the sealing property and the electricity saving performance are improved, and meanwhile, the manufacturing cost and the using cost are reduced.

Description

Technical field [0001] The present invention relates to the field of air-conditioning accessories, in particular to an electric commutator. Background technique [0002] The electromagnetic four-way reversing valve on the existing air conditioner is mainly composed of a main valve, a control valve 1 and a capillary tube. The main valve is composed of a slider 2 and a piston 3 to form a movable valve core. The main valve has through holes at both ends of the valve body to allow the capillary tubes at both ends to communicate with the space in the valve body. The two ends of the slider 2 are respectively fixed with a piston 3 and a piston 3. The spaces on both sides can be communicated through the exhaust holes on the piston 3. The control valve consists of a valve body and an electromagnetic coil. There is a needle valve core in the valve body. There are three (or four) capillary tubes connected between the main valve and the control valve to form a whole four-way reversing val...

AI Technical Summary

Problems solved by technology

[0007] Since the electromagnetic four-way reversing valve must rely on air pressure to push the slider 2 to reversing, when the pressure is not enough, it is easy to cause the slider 2 to not reversing in place, causing the air conditioner to malfunction, and in severe cases, the entire compressor can be scrapped or broken. other serious accident

[0008] The manufacturing process is complicated and requires a lot of special equipment
