  • Patent number: 10273668
    Abstract: An automatic water faucet device 1 for automatically discharging water when an object to be detected is detected has: a sensor 14 that detects the object; a first water discharge part 12 that performs foamy water discharge; a second water discharge part 13 that performs spray water discharge; and a controller 40 that performs control for switching between the foamy water discharge from the first water discharge part 12 and the spray water discharge from the second water discharge part 13, wherein the controller 40 performs the foamy water discharge from the first water discharge part 12 while the sensor 14 detects the object, and when the sensor 14 no longer detects the object, the controller 40 stops this foamy water discharge, and thereafter performs spray water discharge from the second water discharge part 13 for a predetermined period.

  • Patent number: 10060107
    Abstract: An automatic water faucet device 1 includes: an electrolysis tank 37 that electrolyzes water to generate electrolyzed water; a second water discharge part 13 for discharging the electrolyzed water, a second flow path 18 that extends from the electrolysis tank 37 to the second water discharge part 13; a second solenoid valve 28 that switches between supply and blocking of normal water with respect to the electrolysis tank 37, and a controller 40 that controls the electrolysis tank 37 and the second solenoid valve 28. The controller 40 energizes the electrolysis tank 37 to discharge the electrolyzed water and thereafter stops the energization of the electrolysis tank 37 and maintains an open state of the second solenoid valve 28, to stop the supply of the electrolyzed water to the second flow path 18 and to supply normal water to the second flow path 18.
