Problems solved by technology

Refrigerators currently on the market, especially refrigerators with freezing / refrigerating / variable temperature functions, often use various electric valves in the prior art to control the flow direction of their refrigerants, but in practical applications, there are the following problems: using traditional When the bistable solenoid valve is switching the working state, the internal slider hits the valve body to generate noise, which seriously affects the quality of the refrigerator; a rotary electric switching valve is used, which is controlled by a stepping motor to drive the slider in different positions. Switching between working states, however, if the temperature of the stepping motor is too high, the magnetic material of the motor will demagnetize, resulting in a drop in torque or even out of step, reducing the reliability of the electric switching valve; the slider of the existing electric switching valve is on the valve seat When the upper side is doing rotary motion, the impurities in the system are easy to block the outlet position of the base, causing the slider to be stuck and causing the electric switching valve to fail
