DEVICE FOR ELIMINATING STANDBY POWER CONSUMPTION OF ELECTRONIC APPLIANCE HAVING INFRARED REMOTE CONTROL SWITCH CAPABILITY

A device for eliminating standby power consumption of an electronic appliance having infrared remote control switch capability is provided, which includes: a control unit; an infrared remote control signal receiving unit connected thereto; an infrared remote control signal transmitting unit, connected to the control unit; a controlled electronic appliance power supply switch unit, connected to the control unit, a power supply unit, an external power source and a power input end of a controlled electronic appliance; and the power supply unit of the device, connected to the control unit, the controlled electronic appliance power supply switch unit, and the external power source. For the device for eliminating standby power consumption of an electronic appliance having infrared remote control switch capability, during initial installation and setting, an infrared remote power-on/off signal of the controlled electronic appliance and a preheating time after the power source of the controlled electronic appliance is turned on are received, detected and stored. In subsequent use, the power supply of the controlled electronic appliance is turned off upon receiving the infrared remote control power-off signal, the power supply of the controlled electronic appliance is turned on upon receiving the infrared remote control power-on signal, and after the controlled electronic appliance finishes preheating, an infrared remote control power-on signal is transmitted to the controlled electronic appliance to turn on the controlled electronic appliance. Therefore, without changing normal remote power-on/off operations of the user, standby power consumption of the electronic appliance having infrared remote control switch capability is eliminated.
