In the electrolytic ionized water supply apparatus of the present embodiment configured as described above, the ON-OFF switch 103 is turned off (the water supply valve 12 and each Drain valve 8
2, 92 are kept closed and the DC power supply 102
Is turned off, that is, the state in which a predetermined DC voltage is not applied to the electrodes 26 and 27). When the switch is turned on, the following operations and are successively obtained, and the operations are repeatedly obtained. Both water storage tanks 40,
The water level within 50 is low (water level detected by low water level sensors 44, 54) and high water level (high water level sensors 45, 55).
(Water level detected by the water).

After the two drain valves 82 and 92 are opened and held for a set time, they are closed.
All of the ionized water in the chambers 0 and 50 is discharged), and both the discharge valves 62 and 72 are opened and closed after a predetermined time (provided that the low water level sensors 44 and 54 are OFF). After that, all the ionic water is discharged), and then both the discharge valves 62, 72 are inoperable (the respective discharge valves 62, 72 are turned on even if the respective push button switches 105, 106 are turned ON). (Inoperative state).

Next, the water supply valve 12 is opened, and the DC power supply 102 is turned on (a state in which a predetermined DC voltage is applied to the electrodes 26 and 27). The ionic water is led to each of the water storage tanks 40 and 50 through 32, and is stored in each of the water storage tanks 40 and 50. Thus, each water storage tank 40,
The water level in 50 rises to the low water level, and both low water level sensors 4
When the valves 4 and 54 are turned on, the inoperable state of both the water injection valves 62 and 72 is released and the water can be operated (when each of the push button switches 105 and 106 is turned on, each of the injection valves 62 and 72 is operated). State), and according to the state of the changeover switch 104, each lamp L1 or L1
2 and L3 or L4 light up. That is, when the changeover switch 104 is in the positive state, the acidic ionic water is stored in the water storage tank 40 and the alkaline ionic water is stored in the water storage tank 50. Therefore, the red lamp L1 is turned off with the blue lamp L2 and the red lamp L3 turned off. And blue lamp L4
Lights up and the changeover switch is in the reverse state,
Since alkaline ionized water is stored in the water storage tank 40 and acidic ionized water is stored in the water storage tank 50,

In the ON state of No. 3, when the changeover switch 104 is switched from the normal state to the reverse state or from the reverse state to the normal state in order to switch the polarity of the voltage applied to the electrolytic cell 20, the water supply valve 12 is closed during the generation operation of the electrolytic ionic water. DC power supply 1
02 is turned off and the production of each ionized water in the electrolytic cell 20 is interrupted. If the generation of the electrolytic ionized water is interrupted, this state is maintained. , The drainage valves 82 and 92 are opened and held for a set time and then closed (this drains all the ionized water in the water storage tanks 40 and 50), and the low water level sensors 4
The injection valves 62, 72 are opened on condition that the 4, 54 are OFF, and after a predetermined time, the injection valves 62, 72 are closed (thereby discharging all the ionized water in the injection pipes 61, 71),

Is also possible.

When the ON-OFF switch 103 is operated from ON to OFF to stop the electrolytic ionized water supply device, the water supply valve 12 is closed and the DC power supply 102 is turned off if the electrolytic ionized water is generated. The generation of each ionic water in the electrolytic cell 20 is interrupted, and if the generation of the electrolytic ionic water is interrupted, that state is maintained, and the on / off state of each of the lamps L1, L2, L3, and L4 is maintained. Is done. In such a state, when each of the push button switches 105 and 106 is turned ON, each of the discharge valves 62 and 72 is in an open state (operable state). Although it can be used, when the ionic water in each of the water storage tanks 40, 50 is reduced by use and one of the low water level sensors 44, 54 is turned off, both the discharge valves 62,
72 is kept in an inoperable state and all the lamps L1, L2, L3, L4 are turned off.

As is apparent from the above description, in the present embodiment, when the voltage application polarity is switched from the normal state to the reverse state or vice versa, each of the water storage tanks 40 and 50 is switched.
After the entire amount of each ionic water is discharged from the drainage devices 80 and 90, the reverse ionic water is supplied to each of the water storage tanks 40 and 50 from the electrolytic cell 20 whose voltage application polarity has been switched by the polarity switching device 101, respectively. , Electrolytic cell 2
