Abstract

An automatic faucet device capable of cleaning and sterilizing a human body of a user with no stress given to the user. The device includes: a water supply head; a first solenoid valve interposed in the course of a pipe connecting the water supply head to a pre-cleaning water source; a second solenoid valve interposed in the course of a pipe connecting the water supply head to an ozone-water source; and a sensor for detecting the presence of a substance such as a hand of a human body under a discharge port of the water supply head. The first solenoid valve is opened for a specific period of time A in response to a signal detected by the sensor, and the second solenoid valve is opened for a specific period of time C after an elapse of a specific period of time B since starting of the opening of the first solenoid valve. A graphic indicator including arrays of LEDs, which is disposed on the upper surface of the water supply head, controls the turn-on/off of the arrays of light emitting diodes in cooperation with the solenoid valve control means and schematically, graphically indicating both an elapsed time within the specific period of time B and an elapsed time within the specific period of time C.
