The alkaline ionized water tank 50 has a larger capacity than the acidic ionized water tank 40, and the alkaline ionized water outlet pipe 34 is used during the ionized water producing operation of the apparatus.
The alkaline ionized water introduced through the alkaline ionized water is stored and the acidic ionized water and the acidic ionized water derivation pipe 33, the second switching valve 37, the connecting pipe 36 and the alkaline water which are introduced through the alkaline ionized water derivation pipe 34 during the pipe cleaning operation of the device are stored.

A control means for controlling each operation of the power supply circuit 62, the first switching valve 35, the second switching valve 37, and the electric discharge pump 52 is provided so that the following operations can be obtained.

[Operation during Ionized Water Production Operation] In the electrolytic ionized water production apparatus configured as described above, when the ionized water production operation switch SW1 is started in the illustrated state and a production start signal is output, electrical control is performed. The device 60 activates the electric supply pump 22 to move from the dilute salt water tank 20 to the electrolytic cell 1.
While supplying treated water to the electrode chambers 14 and 15 of 0,
The electrode switching means 61 is de-energized, and the power supply circuit 62
The ON signal is output to the DC voltage between the positive electrode and the negative electrode of the power supply circuit 62 to a predetermined value. Therefore, the electrode 11 of the electrolytic cell 10 is connected to the positive electrode of the power supply circuit 62, and the electrode 12 is connected to the negative electrode of the electrolytic cell 10. The acidic ionized water having a predetermined pH flowing to the discharge pipe 31 is guided from the first discharge pipe 31 to the acidic ionized water discharge pipe 33 through the first switching valve 35, and then the acidic ionized water tank 40.
Flow into the second discharge pipe 32 from the electrode chamber 15 and the alkaline ionized water flows from the second discharge pipe 32 into the first switching valve 3
After passing through 5, it is led to the alkaline ionized water outlet pipe 34 and flows into the alkaline ionized water tank 50. Therefore,
The acidic ionized water stored in the acidic ionized water tank 40 can be appropriately used by opening the pouring cock 43.

When the water level in the acidic ionized water tank 40 reaches the upper limit L1 and the water level sensor 44 detects the water level in the acidic ionized water tank 40 by the above-mentioned positive voltage application operation, the electric control unit 60 stops the electric supply pump 22. At the same time, the power supply circuit 61 receives an OFF signal from the electric control device 60, the DC voltage between the plus electrode and the minus electrode is set to zero, and the ion water generation operation is interrupted. Further, when the water level in the acid ion water tank 40 reaches the lower limit L2 due to the use of the acid ion water and the water level sensor 44 detects this,
The electric supply pump 22 is driven by the electric control device 60, and the power supply circuit 61 is turned off from the electric control device 60.
Upon receiving the N signal, a DC voltage having a predetermined value is applied between the positive electrode and the negative electrode, and the ionized water production operation is restarted. On the other hand, when the water level in the alkaline ionized water tank 50 reaches the upper limit L3 and the water level sensor 51 detects it due to the ionized water generation operation by applying the positive voltage described above, the electric control device 60 drives the electric discharge pump 52 to cause the alkaline discharge. The alkaline ionized water in the ionized water tank 50 is discharged to the outside through the discharge pipe 53, and by this operation, the water level in the alkaline ionized water tank 50 is the lower limit L4.
When the water level sensor 51 detects this, the electric control device 60 stops the electric discharge pump 52.

By the way, when the accumulated time of the above-described ionized water generation operation by applying a positive voltage (the reverse rotation time setting timer (not shown) provided in the electric control device 60 accumulates time) reaches a set time (for example, 2 hours), the electric control is performed. Both the electrode switching means 61 and the first switching valve 35 are switched by the device 60, and reverse ionized water is generated in the electrode chambers 14 and 15 of the electrolytic cell 10 and flows from the electrode chamber 14 to the first discharge pipe 31. The alkaline ionized water is guided from the first discharge pipe 31 to the alkaline ionized water discharge pipe 34 through the first switching valve 35, and the acidic ionized water flowing from the electrode chamber 15 to the second discharge pipe 32 is discharged from the second discharge pipe 32. It is led to the acidic ionized water outlet pipe 33 through the first switching valve 35.

The detailed operation at the time of this reverse rotation operation is as follows, and when the cumulative time of the above-mentioned ion water production operation by the positive voltage application reaches the set time, the power supply circuit 62 is turned off.
A signal is output to reduce the DC voltage between the positive electrode and the negative electrode of the power supply circuit 62 to zero, and a switching signal is output to the second switching valve 37 to switch communication between the second switching valve 37 and the upstream side pipe. The portion 33a communicates only with the connecting pipe 36, and the electrode switching means 61 is energized so that the electrolytic cell 1
The negative electrode of the power supply circuit 62 is connected to the electrode 11 of 0, the positive electrode is connected to the electrode 12, and
A switching signal is output to the switching valve 35 and the first switching valve 35
Switches the communication, the discharge pipe 31 communicates with the discharge pipe 34, the discharge pipe 32 communicates with the discharge pipe 33, and then an ON signal is output to the power supply circuit 62 to generate a direct current between the positive electrode and the negative electrode of the power supply circuit 62. When the voltage reaches a predetermined value and about 3 minutes thereafter, a return signal is output to the second switching valve 37, the second switching valve 37 switches communication, and the upstream side pipe portion 33
a communicates only with the downstream pipe portion 33b. Therefore, the reverse operation can prevent water other than the acidic ion water having a predetermined PH from flowing into the acidic ion water tank 40, and the reverse operation electrically causes the electrodes 11 and 12 of the electrolytic cell 10 to electrically operate. It is possible to prevent acidic ionized water containing deposits such as calcium and sodium that are removed from the electrode 12 by the reverse electrolysis cleaning from flowing into the acidic ionized water tank 40. Hydrogen embrittlement damage of the electrode 12 can be suppressed by preventing a large amount of hydrogen ions from remaining around. The cumulative time of the ion water generation operation by the reverse voltage application after the reverse rotation operation is again measured by the reverse time setting timer provided in the electric control device 60.

The above-mentioned electrode switching means 61 and the first switching valve 3
The interlocked reversing operation of 5 is automatically performed at every set time unless the generating operation switch SW1 is stopped, whereby the electrodes 11 and 12 of the electrolytic cell 10 are electrically backwashed and the reversing operation is performed. The discharge pipe, in which the alkaline ionized water is flowing before, is washed by the acidic ionized water flowing by reversing. When the generation operation switch SW1 is stopped, a generation stop signal is output, and the electric control device 60 stops the electric supply pump 22 and
An OFF signal is output to the power supply circuit 62 so that the DC voltage between the positive electrode and the negative electrode of the power supply circuit 62 becomes zero, the electrode switching means 61 is de-energized, and the first switching valve 35 is illustrated. Then, the reversal time setting timer (not shown) provided in the electric control device 60 is reset to make the cumulative time zero.

[Operation during pipe cleaning operation] When the cleaning switch SW2 is started during the above-described ion water generation operation, a cleaning start signal is output and the electrode switching means 61 is output.
And the second switching valve 37 is switched, and the electrode switching means 61 is energized if it is in a non-energized state and deenergized if it is in an energized state, and the upstream pipe portion 33a is communicated only with the connecting pipe 36. Then, in the electrolytic cell 10, ionic water that is the reverse of that before the operation of the cleaning switch SW2 is generated, and the alkaline ionic water is guided from the discharge pipe to the acidic ionic water outlet pipe 33 through the first switching valve 35 and further upstream. From the pipe portion 33a through the second switching valve 37, the connecting pipe 36, the alkaline ionized water outlet pipe 3
4 is introduced into the alkaline ionized water tank 50, and the acidic ionized water is introduced from the discharge pipe to the alkaline ionized water outlet pipe 34 through the first switching valve 35 and flows into the alkaline ionized water tank 50. Therefore, it is possible to dissolve and remove the deposits deposited on the alkaline ionized water outlet pipe 34, which is supplied with the alkaline ionized water during non-washing, with the acidic ionized water for cleaning. The passage diameter of 34 can be sufficiently secured. Therefore, it is possible to save the labor of exchanging the alkaline ionized water outlet pipe 34 where precipitates such as calcium and sodium tend to accumulate. Further, since it is not necessary to circulate chemicals such as dilute hydrochloric acid to remove the deposits, it is not necessary to prepare a pump and a tank dedicated to these chemicals.

Further, when the cleaning switch SW2 is stopped, a cleaning stop signal is output, the electrode switching means 61 is immediately returned to the state before cleaning, and the second switching valve 37 at the time point when about 3 minutes have passed. Is returned to the state before cleaning,
The reverse rotation time setting timer is reset to zero the cumulative time. Therefore, it is possible to prevent water other than the acidic ionized water having a predetermined pH from flowing into the acidic ionized water tank 40, and it is possible to suppress the number of reversals of voltage application.

In the embodiment shown in FIG. 1, the connecting pipe 36 is connected to the intermediate portion of the acidic ionized water outlet pipe 33 and the intermediate portion of the alkaline ionized water outlet pipe 34 to simplify the pipe construction.

4, the alkaline ionized water is not guided through the connecting pipe 36 to the middle part of the flow path 4, and only the acidic ionized water flows through the alkaline ionized water outlet pipe 34 over the entire length. Therefore, the entire alkaline ionized water outlet pipe 34 can be washed with the acidic ion water. As a result, the passage diameter of the alkaline ionized water outlet pipe 34 can be sufficiently secured. The overflow pipe 45 shown in FIG. 2 is a chlorine gas discharged from the excess acidic ionized water in the acidic ionized water tank 40 and the acidic ionized water in the acidic ionized water tank 40 and accumulated in the space above the tank 40. The alkaline ionized water tank 50 has a function of guiding (having a larger specific gravity than air) to the alkaline ionized water tank 50, and has an upper end opened in the tank above the upper limit water level L1 of the acidic ionized water tank 40 and an alkaline ionized water tank at the lower end.
