Title:
STANDBY POWER CUT-OFF DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/018012
Kind Code:
A1
Abstract:
The present invention relates to a standby power cut-off device provided on a power line connected from commercial alternating current power source to the inside of an electrical device, the device comprising: a manual switch for supplying the commercial alternating current power source or cutting off the supply thereof; a solid state relay for supplying the commercial alternating current power source to an output side if the current flows to an input side according to the operation of the manual switch; a low power supply unit for converting the voltage of the commercial alternating current power source supplied by the solid state relay and supplying same; a microprocessor for receiving the power supplied by the low power supply unit, and controlling the operation of the standby power cut-off device; a control signal generator for transmitting a control signal to the microprocessor if the current flows according to the operation of the manual switch; a capacitor, which is charged or discharged according to the operation of the manual switch; and a resistance allowing the charging voltage of the capacitor to be greater than the operation voltage of the control signal generator, and thus current continuously flows to the control signal generator when the manual switch is operated, that is, when the electrical device is tuned on or off, so that an erroneous operation caused by multi-operation control of the microprocessor is prevented.
