Summary of the invention
The purpose of this invention is to provide a kind of family appliance standby energy-saving device, utilize this energy-saving appliance that household electrical appliances are implemented outage shutdown standby, and this power consumption when standby of energy-saving appliance be 0.1W, adopt this energy-saving appliance after the household electrical appliances power savings remarkable.
A kind of family appliance standby energy-saving device, comprise power circuit 1, infrared remote receiver 2, current sensor 3, single-chip microcomputer 4, relay circuit 5 is characterized in that: the termination power A end on the former limit of transformer T, its other end connects a moving contact of variable resistor Ry and relay G K switch respectively, and corresponding stationary contact connects household electrical appliances power supply A ' end; Power supply B end is connected with the other end of variable resistor Ry and another moving contact of K switch respectively by behind the fuse F, and corresponding stationary contact is connected with household electrical appliances power supply B ' end; One end of transformer T secondary is the 6th port 6 of connecting resistance R, controllable silicon DK negative pole, single-chip microcomputer 4 respectively, the other end of transformer T secondary, the other end of resistance R, controllable silicon DK plus earth; First port one of infrared remote receiver 2 second ports 2, single-chip microcomputer 4, the 3rd port 3 of current sensor 3 are all+5V, the 3rd port 3 ground connection of infrared remote receiver 2 first port ones, single-chip microcomputer 4, the 3rd port 3 of infrared remote receiver 2 is connected with second port 2 of single-chip microcomputer 4; First port one of current sensor 3 meets variable resistor Ry, and its second port 2 connects the other end of variable resistor Ry, five-port 5 ground connection of current sensor 3; The collector of the 4th port 4 difference connecting resistance R1 of current sensor 3 and negative pole, triode Q1 and the Q2 of R2, diode D1 and D2, its voltage is+12V; The 4th port 4 of single-chip microcomputer 4 is connecting resistance R3 and R5 respectively, its five-port 5 is connecting resistance R4 and R6 respectively, triode Q1 base stage is connected with resistance R 1 other end with triode Q3 collector respectively, triode Q2 base stage is connected with resistance R 2 other ends with triode Q6 collector respectively, corresponding with the resistance R 3~R6 respectively connection of triode Q3~Q6 base stage, triode Q1 emitter, triode Q4 collector, diode D1 positive pole, diode D3 negative pole, input end of relay G interconnects, triode Q2 emitter, triode Q5 collector, diode D2 positive pole, diode D4 negative pole, another input end of relay G interconnects; Single-chip microcomputer 4 adopts the HT series monolithic.
With the televisor is example, and the mode of operation of this energy-saving appliance is: with the attaching plug of televisor be inserted in the output terminals A of this energy-saving appliance ' and B ' (socket) on, utilize TV remote controller to open infrared remote receiver 2, then this telepilot is turned on televisor; To shut down to televisor, with telepilot infrared remote receiver 2 be done disposable shutdown and get final product.
As shown in Figure 1, after infrared remote receiver J receives remote command, signal is passed to current sensor LEM, current sensor judges whether household electrical appliances enter duty, when household electrical appliances are in running order, sensor is passed to singlechip CPU with working signal, after CPU carries out information processing, opens time pulse relay and powers to household electrical appliances; After telepilot cut out household electrical appliances, sensor cut out time pulse relay in one minute, cut off the household electrical appliances power supply.
With prior art relatively, advantage of the present invention is: behind the household electrical appliance configuration standby energy-saving device, household electrical appliance power supply during standby is turned off and not power consumption, and standby energy-saving device power consumption during standby is 0.1W, and bottom line is reduced in the family appliance standby power consumption.
