Abstract:
To provide an electronic faucet device causing no failure at power failure with excellent electric power efficiency.SOLUTION: There is provided an electronic faucet device that controls water discharge by controlling a motor valve comprising: a control part controlling the motor valve by utilizing a commercial power supply as power source; a power failure detecting part which detects power failure of the commercial power supply; an electric double layer capacitor which stores the electric power to supply to the motor valve during power failure of the commercial power supply; a step-up part which boosts the voltage of the electric double layer capacitor; and a motor valve drive capacitor which further stores the output of the step-up part. The control part intermittently supplies the motor valve with the electric power stored in the motor valve drive capacitor during power failure of the commercial power supply.SELECTED DRAWING: Figure 3
