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.

First claim

The invention claimed is:

1. A water faucet device comprising:
a functional water generation part configured to operate by a supplied current, and to reform water so as to generate functional water;
a functional water discharge part configured to discharge the functional water generated by the functional water generation part;
a functional water flow path extending from the functional water generation part to the functional water discharge part, and configured to allow the functional water to flow; and
a controller configured to control the functional water generation part,
wherein the controller is configured to discharge the functional water having first concentration from the functional water discharge part through the functional water flow path, and thereafter to supply the functional water flow path with the functional water having second concentration lower than the first concentration.

2. The water faucet device according to claim 1 ,
wherein the functional water generation part is configured to reform water by electrolysis to generate the functional water, and
wherein the controller is configured to control energization power of the functional water generation part to discharge the functional water having the first concentration from the functional water discharge part, and thereafter to supply the functional water having the second concentration to the functional water flow path.

3. The water faucet device according to claim 2 ,
wherein the controller is configured to apply predetermined energization power to the functional water generation part to discharge the functional water having the first concentration from the functional water discharge part,
wherein the controller is configured to set the energization power of the functional water generation part to 0 to stop the energization of the functional water generation part, so that normal water is supplied to the functional water flow path, and
wherein the normal water has the second concentration which is 0 and has not been reformed by the functional water generation part.

4. The water faucet device according to claim 3 , further comprising a solenoid valve configured to switch between supply and blocking of the normal water with respect to the functional water flow path, by opening and closing,
wherein, after the functional water is discharged from the functional water discharge part through the functional water flow path by the energization of the functional water generation part, the controller is configured to stop the energization of the functional water generation part to stop the supply of the functional water to the functional water flow path, and is configured to control the solenoid valve to supply the normal water to the functional water flow path.

5. The water faucet device according to claim 4 ,
wherein the solenoid valve is provided on an upstream side of the functional water generation part, and is configured to switch between supply and blocking of the normal water with respect to the functional water flow path through the functional water generation part, by opening and closing, and
wherein the controller is configured to open the solenoid valve and energize the functional water generation part to discharge the functional water from the functional water discharge part through the functional water flow path, and then the controller is configured to stop the energization of the functional water generation part and maintain an open state of the solenoid valve for predetermined time to stop the supply of the functional water to the functional water flow path such that the normal water is supplied to the functional water flow path.

6. The water faucet device according to claim 5 ,
wherein, after the energization of the functional water generation part is stopped, the controller is configured to supply the functional water flow path with the normal water having quantity at least larger than a volume of the functional water flow path.

7. The water faucet device according to claim 4 ,
wherein, after the energization of the functional water generation part is stopped, the controller is configured to supply the functional water flow path with the normal water having quantity at least larger than a volume of the functional water flow path.
