In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below by combining the specific drawings.

As shown in fig. 1, the wall-mounted air conditioner zero power consumption standby intelligent power line includes a power plug LN1, an L1 end and an N2 end, a1 end and an a2 end of a switch and control signal, an optical coupler IC1, an optical coupler IC2, an optical coupler IC3, bridge rectifier diodes D1-D4, a diode D5, a power supply transformer T1, a voltage stabilizing diode VD1, a capacitor C1, a capacitor C2, a capacitor C3, a capacitor C4, a resistor R1, a resistor R2, a resistor R3, a resistor R4, and a resistor R5;

The working principle is as follows: firstly, connecting a pin 1 and a pin 2 of an IC1 optocoupler of a zero-power consumption remote control intelligent power line of a wall-mounted air conditioner to a switch and control signal end of a main control panel power supply transformer T1 of a wall-mounted air conditioner indoor unit by using connecting wires, connecting a B1 end and a B2 end to primary two ends of a main control panel power supply transformer of the wall-mounted air conditioner indoor unit, connecting an L1 end and an N2 end to a main input circuit power supply circuit which is controlled by the main control panel and needs 220V power supply in the wall-mounted air conditioner, after the circuit is connected, inserting an LN1 plug into a 220V power socket, reducing the voltage of the L end 220V voltage by using a capacitor C1, rectifying the voltage by a bridge type consisting of D1-D2 diodes, outputting 5V voltage after filtering by using a C2 capacitor and a VD1 voltage stabilizing diode, connecting one voltage to a pin 1 of an IC2 capacitor infrared receiving head, and pressing, at the moment, an IC2 infrared receiving head receives an infrared signal transmitted by an air conditioner remote controller, a low level can be output at a pin 3, the capacity of a C4 capacitor is very small, a triode Q1 can be conducted at the moment, a collector outputs a high level to enable the C3 capacitor to be charged quickly and simultaneously pass through an R3 resistor to a base electrode of a triode Q2, so that a Q2 triode is conducted, an emitter outputs a high level to enable the triode Q3 to be conducted through an R5 resistor, an IC3 optical coupler is powered to work, so that the IC3 optical coupler internally emits light and is powered to work, a bidirectional trigger silicon controlled rectifier is triggered to conduct inside the IC3 optical coupler, 220V is output at the pin 3 to enable a control panel power transformer T1 in a wall-mounted air conditioner indoor unit to be powered to work, 12V voltage is output at a secondary side. If the air conditioner start key is pressed again, after a remote controller receiving head on the wall-mounted air conditioner indoor unit receives an infrared start signal, the main control panel outputs various control voltages, various power supply control circuits of the air conditioner are turned on, the air conditioner works formally, meanwhile, the main control panel circuit of the wall-mounted air conditioner indoor unit is connected to

pins

1 and 2 of an IC1 optical coupler, so that the IC1 optical coupler internally emits light and obtains electricity to work, a photosensitive triode in the IC1 optical coupler is triggered to be conducted, 3 pins output high level to charge a capacitor, meanwhile, a Q2 triode is kept to be conducted through an R3 resistor, a Q3 triode is kept to be conducted, and an IC3 optical coupler is kept to be in a working state. When the infrared receiving head of the IC2 does not receive the infrared signal any more, the 3 pin outputs high level to cut off the transistor Q1, and the air conditioner works normally.

When the air conditioner needs to be shut down, after a shutdown key of an air conditioner remote controller is pressed, and a receiving head in the air conditioner receives a shutdown signal, a main control board in the air conditioner can shut down the voltage of each control end, at the moment, the control voltage of a pin 1 and a pin 2 of an optical coupler of the IC1 can be lost, the optical coupler of the IC1 is not operated when the power is lost, after the IC2 no longer receives the infrared signal, the C3 capacitor makes the Q1 triode keep on through the R3 resistor, the Q2 triode is on, the Q3 triode is on, the IC3 optocoupler is on, makes the transformer T1 of the air conditioner indoor unit keep on the power-on state, after two minutes, the C3 capacitor is discharged, the Q2 triode is cut off, the Q3 triode is cut off, the IC3 optocoupler is not operated when power is lost, the power supply transformer T1 in the main machine control panel of the air conditioner is powered off, therefore, the power supply of the main machine control panel in the air conditioner is turned off after two minutes of delay, the zero power consumption standby of the air conditioner after the air conditioner is turned off is achieved, and meanwhile, the remote control switch function is realized. Because the capacitance of the C1 capacitor is very small, the standby with zero power consumption is achieved, the electricity is saved, the service life of circuit components in the air conditioner is protected, and the service life of the components can be shortened due to long-term electrification of the components in the air conditioner.
