An automatic water faucet devicefor automatically discharging water when an object to be detected is detected has: a sensorthat detects the object; a first water discharge partthat performs foamy water discharge; a second water discharge partthat performs spray water discharge; and a controllerthat performs control for switching between the foamy water discharge from the first water discharge partand the spray water discharge from the second water discharge part, wherein the controllerperforms the foamy water discharge from the first water discharge partwhile the sensordetects the object, and when the sensorno longer detects the object, the controllerstops this foamy water discharge, and thereafter performs spray water discharge from the second water discharge partfor a predetermined period.

Automatic water faucet device

An automatic water faucet deviceincludes: an electrolysis tankthat electrolyzes water to generate electrolyzed water; a second water discharge partfor discharging the electrolyzed water, a second flow paththat extends from the electrolysis tankto the second water discharge part; a second solenoid valvethat switches between supply and blocking of normal water with respect to the electrolysis tank, and a controllerthat controls the electrolysis tankand the second solenoid valve. The controllerenergizes the electrolysis tankto discharge the electrolyzed water and thereafter stops the energization of the electrolysis tankand maintains an open state of the second solenoid valve, to stop the supply of the electrolyzed water to the second flow pathand to supply normal water to the second flow path

Water faucet device

An automatic faucet has a closing valve, a controller of the closing valve, a discharging member connected to the closing valve through a pipe, an optical sensor connected to the controller through an electric wire and a cylindrical faucet body through which the conduit and the electric wire are passed. The discharging member and the optical sensor are directed in the same direction, assembled in a unit, and installed in a single space formed in the front end portion of the faucet body.
