The supplied ion is electrolyzed in the electrolyzer 20 to generate each ion water, and the acidic ion water with increased hydrogen ions is discharged from the electrode chamber 24 of the plus side electrode 22 to the discharge pipe 31 and the flow path switching valve in the positive state. The alkaline ionized water, which has been sent to a large-capacity acidic ion water storage tank (not shown) through V3 and the outlet pipe 33, and has increased hydroxide ions from the electrode chamber 25 of the negative electrode 23 is in a positive state with the discharge pipe 32. It is sent to a large-capacity alkaline ionized water storage tank (not shown) through the flow path switching valve V3 and the outlet pipe 34.
When the flow path switching valve V3 is in the reverse state shown by the phantom line in FIG. 1 and the ion water production in the in-phase state is changed to the ion water production in the reverse phase state, the above-described step 234 is performed.
Instead of the above, the processing of step 235 is executed, and the alkaline ionized water in which the hydroxide ions have increased from the electrode chamber 24 of the negative electrode 22 has a flow path switching valve V in a state opposite to the discharge pipe 31.
3 and a lead-out pipe 34, and sent to a large-capacity alkaline ionized water storage tank (not shown).
From the electrode chamber 25 of No. 3, the acidic ionized water with increased hydrogen ions is in the state opposite to the discharge pipe 32, and the flow path switching valve V3 and the outlet pipe 33.
Through a large-capacity acidic ionized water storage tank (not shown).

In the ion water production operation in the reverse phase state described above, is the production switch 102 turned off?
Until the time value t1 of the timer 106 reset at 37 reaches the first set value ta, the processes of steps 238 and 239 are repeatedly executed and maintained, and the generation switch 10
2 is turned off, steps 240, 241, 24
When the process 2 is performed, both electrodes 22, 23 of the electrolytic cell 20 are
The voltage application to the electrolysis tank 20 is stopped, the water supply valve V1 is closed, and the water supply and the electric power supply to the electrolytic cell 20 are stopped to stop the generation operation. On the other hand, when the above-mentioned measured value t1 reaches the first set value ta, the processing from step 243 onward in FIG. 5 is executed,
The restart described below is started.

Steps 243 to 256 in FIG. 5 are basically the same as steps 215 to 228 in FIG. 3 (only steps 253 and 256 are different), and step 243.
Then, the voltage application to both electrodes 22 and 23 of the electrolytic cell 20 is stopped, a closing signal is output to the water supply valve V1 in step 244, and it is determined in step 245 whether or not the flow sensor S is OFF. If "YES" is determined in the step 245, the processes of steps 247, 248, 249 and 250 are sequentially executed, and if "NO" is determined in the step 245, the process of step 246 is executed. Returning to step 245, in step 246, the failure alarm routine is executed and an alarm is issued.

In step 247, the switching routine of the flow path switching valve V3 is executed to switch to the reverse state when the flow path switching valve V3 is in the positive state, and to the normal state when it is in the reverse state. . In step 248, an open signal is output to the drain valve V2 to open the drain valve V2, and step 2
At 49, the timer 106 is reset, the measured value t1 is set to zero, and the timer is restarted. Further, in step 250, it is judged whether or not the measured value t1 of the timer 106 reset in step 249 is equal to or more than the drainage set value ts, and “N
When it is determined to be "O", the process of step 250 is repeatedly executed, and when it is determined to be "YES", the processes of steps 251 and 252 are executed.

In step 251, a closing signal is output to the drain valve V2 to close the drain valve V2, and in step 252, the integration timer 1 reset in step 227 of FIG.
It is determined whether the time value t2 of 07 is equal to or greater than the second set value tb. The measured value t2 of the integration timer 107 is the second set value tb.
When it is less than the above, it is determined to be “NO” in step 252 and the processing from step 230 onward in FIG. 4 is executed, and when the above-mentioned time count value t2 is equal to or more than the second set value tb, “ After "YES" is determined and the processing of steps 253, 254, 255, 256 is executed, the processing of step 202 and subsequent steps in FIG. 2 is executed.

In step 253, the third notification execution routine is executed, and the voice message "The accumulated time of ion water production in the reverse phase state has exceeded the set value. From the ion water production in the reverse phase state to the in-phase state" Please press the mode change permission switch to change to the generation of ionized water. ”. When the user presses the mode switching permission switch 103 in response to this notification, it is determined as "YES" in step 254 and steps 255 and 256 are executed, and the above notification is not transmitted to the user, and the user does not operate the switch 1
When 03 is not pressed, it is determined to be "NO" in step 254, and the processing from step 230 onward in FIG. 4 is executed. This prevents the production operation from being unnecessarily stopped and the user's unexpected change from ion water production in the reverse phase state to ion water production in the in-phase state.

In step 255, the integration timer 10
7 is reset, the measured value t2 is set to zero, and restarted, and in step 256, the fourth notification execution routine is executed, and a voice message "from ion water production in the reverse phase state to ion water production in the in-phase state" Change the outlet of each ionized water, so be careful when using it. " By this notification, the user matches the outlet of the outlet pipe 33 with a large-capacity alkaline ion water storage tank (not shown), and the outlet of the outlet pipe 34 with a large-capacity acidic ion water storage tank (not shown). In addition, prepare for the generation of ionized water in the same phase. Note that the contents of the above-described notification (third notification and fourth notification) in each voice can be changed as appropriate, and can be repeated several times. Further, instead of the notification by each voice, it is also possible to carry out the notification by a notification means such as blinking of a display lamp or ringing of a buzzer.

As is clear from the above description, in the present embodiment, the microcomputer of the control device 100 executes the in-phase control program shown in FIGS. The treated water is electrolyzed with the voltage application polarity and the switching state of the flow path switching valve V3 in the same phase, alkaline ionized water is led to the outlet pipe 33, and acidic ionized water is led to the outlet pipe 34. In the reverse phase generation mode in which the microcomputer of the control device 100 executes the reverse phase control program shown in FIGS. 4 and 5, the polarity of voltage application to the electrolytic cell 20 and the switching state of the flow path switching valve V3 are reversed. The treated water is electrolyzed in the phase state, the acidic ionized water is led to the outlet pipe 33, and the alkaline ionized water is led to the outlet pipe 34.

For switching from the in-phase generation mode to the anti-phase generation mode and from the anti-phase generation mode to the in-phase generation mode, the time count value t2 of the integrating timer 107 is set to the second set value t.
This is performed by turning on the switch 103 in the state of b or more, and by alternately executing the in-phase generation mode and the anti-phase generation mode, the discharge pipes 33 and 34 are respectively supplied. Since the acidic ionized water and the alkaline ionized water are alternately guided, the scales of calcium, magnesium, etc., which are deposited and deposited on the inner walls of the outlet pipes 33 and 34 by the flow of the alkaline ionized water, are automatically dissolved and washed by the acidic ionized water. Therefore, even when used for a long period of time, the scale does not adhere to and deposit on the inner walls of the outlet pipes 33 and 34 in excess of a set value, and the conduit resistance of the outlet pipes 33 and 34 is prevented from abnormally increasing. be able to.

In the present embodiment, the polarity of voltage application to the electrolytic cell 20 and the switching state of the flow path switching valve V3 are both set at the first set time ta in the above-described in-phase generation mode and reverse-phase generation mode. Since the switching can be performed, the scale attached to the electrodes 22 and 23 in the electrolytic cell 20 can be accurately removed, and electrolytic ionized water of substantially uniform quality and quantity can be continuously obtained. it can. Further, at the time of switching for each of the above-mentioned first set times ta, the respective outlet pipes 33, 3
Reverse ion water is supplied from 4 to the electrode chambers 24, 25 of the electrolytic cell 20 in a reverse flow, so that the water in each flow passage including the electrode chambers 24, 25 is quickly neutralized or reverse ionized. Therefore, in the initial stage of restart of the device, it is possible to suppress the hydrogen ions from invading the electrode in the electrode chamber accommodating the negative electrode, and to prolong the life of the electrode. Further, when the reverse ionized water is reversely supplied from the outlet pipes 33 and 34 to the electrode chambers 24 and 25 of the electrolytic cell 20, both electrodes of the water supply tube 11 and the electrolytic cell 20 on the electrolytic cell 20 side of the water supply valve V1 are provided. It is possible to discharge the water in the chambers 24 and 25 to the outside through the drain valve V2 and the drain pipe 13 which are in an open state that hardly inhibits the above-described backflow, and it is possible to shorten the backflow supply time of the reverse ion water. Therefore, the voltage application stop time can be set to be short, the ion water production operation interruption time of the device can be shortened, and the ion water production capacity can be improved.

Further, in the present embodiment, since the sound is notified when the mode is switched to the in-phase generation mode and the reverse-phase generation mode, it is possible to prevent misuse of each ion water. Further, when the switch 103 is not turned on at the time of switching the mode to the in-phase generation mode or the reverse-phase generation mode, the mode switching is prohibited (step 226 in FIG. 3 and FIG. 5).
Therefore, it is possible to prohibit mode switching that does not depend on the user's intention, and prevent misuse of each ionized water.

In the above embodiment, the integration timer 10 is used.
When the switch 103 is turned on in the state where the measured value t2 of 7 is equal to or larger than the second set value tb, the switching from the in-phase generation mode to the anti-phase generation mode and the switching from the anti-phase generation mode to the in-phase generation mode are performed. However, instead of the integration timer 107, a counter for counting the polarity of voltage application to the electrolytic cell 20 in the in-phase or anti-phase generation mode and the switching number of the switching state of the flow path switching valve V3 is provided. The generation mode can be switched when the count value of this counter reaches the set value (the processing contents of steps 224 and 227 of FIG. 3 and the steps 252 and 2 of FIG. 5).
It is also possible to implement (changing the processing contents of 55).
Further, it is carried out without providing the above-mentioned integration timer 107 or counter (steps 224 and 227 of FIG. 3 and FIG.
It is also possible to carry out without steps 252 and 255. Further, in the above embodiment, the integration timer 107
Starts the clocking by the reset signal, interrupts the clocking by the end of the program, and restarts the clocking by the start of the program so that the electrolytic treatment operation time is roughly integrated. Timing is started by the reset signal and the generation operation is interrupted (steps 215 and 216 in FIG. 3 and steps 243 and 244 in FIG. 5).
And the electrolysis treatment operation time is accurately integrated by restarting the generation operation by restarting the generation operation (steps 202 to 209 in FIG. 2 and 230 to 237 in FIG. 4). It is also possible.

Further, in the above embodiment, the polarity of voltage application to the electrolytic cell 20 and the switching state of the flow path switching valve V3 are both set at the first set time ta in the above-described in-phase generation mode and reverse-phase generation mode. Although the switching can be performed, it is also possible to implement it in the above-described in-phase generation mode and reverse-phase generation mode without switching the polarity of voltage application to the electrolytic cell 20 and the switching state of the flow path switching valve V3. is there.
