The water level sensor 44 detects an upper limit water level L1 and a lower limit water level L2, and is connected to the electric control device 60.

The alkaline ionized water tank 50 has a larger capacity than the acidic ionized water tank 40. The alkaline ionized water tank 50 stores alkaline ionized water introduced through the alkaline ionized water derivation pipe 34 during the operation of generating ionized water of the apparatus, and simultaneously cleans the piping of the apparatus.

(35), the control means for controlling each operation of the second switching valve 37 and the electric discharge pump 52 is provided, and the following operations are obtained.

(Operation during ionized water generation operation)

In the electrolytic ion water generating device configured as described above, when the ionized water generation operation switch SW1 is started in the city state and the generation start signal is output, the electric control device 60 starts the electric supply pump 22 to activate the brine tank. In step 20, the process water is supplied to the electrode chambers 14 and 15 of the electrolytic cell 10, the electrode switching means 61 is turned off, and the ON signal is outputted to the power supply circuit 62. The direct current voltage between the positive electrode and the negative electrode of the circuit 62 is brought to a predetermined value. For this reason, the positive electrode of the power supply circuit 62 is connected to the electrode 11 of the electrolytic cell 10, and the negative electrode is connected to the electrode 12, and it is produced | generated by electrolysis in the electrolytic cell 10, and is formed in an electrode chamber. The acidic ionized water having a predetermined pH flowing through the first discharge pipe 31 in 14 is led from the first discharge pipe 31 to the acidic ionized water derivation pipe 33 via the first switching valve 35 to the acidic ionized water tank 40. The alkaline ionized water flowing in to the second discharge pipe 32 from the electrode chamber 15 is introduced into the alkaline ionized water derivation pipe 34 from the second discharge pipe 32 via the first switching valve 35 to the alkaline ionized water. Flows into the tank 50. Therefore, the acidic ionized water accumulated in the acidic ionized water tank 40 can be suitably used by opening the pouring cock 43.

When the water level in the acidic ionized water tank 40 reaches the upper limit L1 by the constant voltage application operation, and the water level sensor 44 detects this, the electric supply pump 22 is operated by the electric controller 60. At the same time as the power supply circuit 61 receives the OFF signal from the electric control device 60, the DC voltage between the positive electrode and the negative electrode becomes zero, and the ionized water generation operation is stopped.

When the water level in the acidic ionized water tank 40 reaches the lower limit L2 due to the use of acidic ionized water and the water level sensor 44 detects this, the electric supply pump 22 is driven by the electric control device 60 and at the same time. The power supply circuit 61 receives the ON signal from the electric control device 60, and a predetermined DC voltage is applied between the positive electrode and the negative electrode to start the ionized water generation operation again. On the other hand, when the water level reaches the upper limit L3 in the alkaline hot water tank 50 by the ionized water generation operation by applying the constant voltage, which is detected by the water level sensor 51, the electric discharge pump (the electric discharge pump) 52) is driven and the alkaline hot water in the alkaline hot water tank 50 is discharged to the outside through the discharge pipe 53, by this operation the water level in the alkaline hot water tank 50 reaches the lower limit (L4) and this is the water level sensor When the 51 detects, the electric discharge pump 52 is stopped by the electric control device 60.

By the way, when the cumulative time of the ionized water generation operation by the constant voltage pressurization (which is accumulated by the inversion time setting timer (not shown) provided with the electric control device 60) becomes the set time (for example, two hours), The electrode switching means 61 and the first switching valve 35 are switched together by the electric control device 60, and reverse ionized water is generated in each of the electrode chambers 14 and 15 of the electrolytic cell 10. The alkaline ionized water flowing from the first discharge pipe 31 to the first discharge pipe 31 is led from the first discharge pipe 31 to the alkaline ionized water derivation pipe 34 via the first switching valve 35, and the electrode chamber 15 is provided. Acid ionized water flowing in the second discharge pipe 32 from the second discharge pipe 32 is led to the acidic ionized water leading pipe 33 via the first switching valve 35.

The detailed operation during this reversal operation is as shown below. When the accumulated time of the ionized water generation operation by the constant voltage pressurization reaches the set time, the OFF signal is output to the power supply circuit 62, and the power supply circuit 62 is turned off. The DC voltage between the positive electrode and the negative electrode becomes zero, and at the same time, a switching signal is output to the second switching valve 37 so that the second switching valve 37 switches communication, and the upstream pipe portion 33a is connected to the connecting pipe. The electrode switching means 61 is energized so that the negative electrode of the power supply circuit 62 is connected to the electrode 11 of the electrolytic cell 10 and the positive electrode is connected to the electrode 12 at the same time. In addition, a switching signal is output to the first switching valve 35 so that the first switching valve 35 switches communication so that the discharge pipe 31 communicates with the discharge pipe 34 and the discharge pipe 32 is withdrawn. In communication with the tube 3, the ON signal is subsequently output to the power supply circuit 62, and the positive electrode of the power supply circuit 62 and the positive electrode. When the DC voltage between the negative electrodes reaches a predetermined value, a return signal is output to the second switching valve 37 at about 3 minutes after that, and the second switching valve 37 switches communication so that the upstream pipe portion 33a ) Communicates only with the downstream pipe part 33b. Therefore, the reverse operation can prevent water other than the acidic ionized water having a predetermined pH from entering the acidic ionized water tank 40, and at the same time, the electrodes 11 and 12 of the electrolytic cell 10 are reversed by the reverse operation. It is possible to prevent the acidic ionized water containing Ca, Na, and the like removed from the electrode 12 from flowing into the acidic ionized water tank 40 by being electrically inverted and washed at the beginning of the reverse voltage pressurization. By preventing a large amount of hydrogen ions from being left around, hydrogen-vulnerable damage of the electrode 12 can be suppressed. Further, the cumulative time of the ion water generation operation by the reverse voltage pressurization after the above reversing operation is again accumulated and counted by the reversing time setting timer included in the electric control device 60. The reversing operation of the above-mentioned electrode switching means 61 and the first switching valve 35 is automatically performed at every set time unless the generation operation switch SW1 is stopped. Thus, each electrode of the electrolytic cell 10 11, 12) are electrically reverse-washed and the discharge pipe in which alkaline ionized water flows before reversal is cleaned by acidic ionized water flowing by reversal. Further, when the generation operation switch SW1 is stopped, the generation stop signal is output, and the electric control device 60 stops the electric supply pump 22 and outputs an OFF signal to the power supply circuit 62 to supply power. The DC voltage between the positive electrode and the negative electrode of the circuit 62 becomes zero, the electrode switching means 61 is in the non-energized state, the first switching valve 35 is in the illustrated state, and at the same time electrical control The inversion time setting timer (not shown) included in the device 60 is reset to zero the accumulated time.

[Operation during piping cleaning operation]

When the washing switch SW2 is started and operated during the ion water generation operation, the washing start signal is output, and the electrode switching means 61 and the second switching valve 37 are switched to thereby switch the electrode switching means 61. In the non-energized state, the state is energized. In the energized state, the upstream pipe portion 33a communicates only with the connection pipe 36. In the electrolytic cell 10, the electrostatic cell 10 is inversely opposite to the operation of the cleaning switch SW2. Ionized water is generated, and alkaline ionized water is led to the acidic ionized water derivation pipe 33 through the first switching valve 35 in the discharge pipe, and further connected to the connecting pipe via the second switching valve 37 from the upstream pipe part 33a. (36), the alkaline ionized water derivation pipe (34) is introduced into the alkaline ionized water tank (50), and the acidic ionized water is led to the alkaline ionized water derivation pipe (34) via the first switching valve (35) in the discharge pipe. It flows into the alkaline hot water tank (50). For this reason, the precipitate precipitated and deposited in the alkaline ionized water derivation tube 34 supplied with alkaline ionized water at the time of non-cleaning of the pipe can be dissolved and removed by acidic ionized water to ensure a sufficient passage diameter of the alkaline ionized water derivation tube 34. can do. Therefore, the trouble of replacing | exchanging the alkaline ionized-water-derived pipe | tube 34 which especially precipitates, such as Ca and Na, tend to accumulate can be skipped. Moreover, since it is not necessary to circulate the chemical | medical agent, such as diluted hydrochloric acid, and to remove a precipitate, it is not necessary to prepare the pump, tank, etc. exclusively for these chemicals.

When the cleaning switch SW2 is stopped, the cleaning stop signal is output, and the electrode switching means 61 returns to the state before cleaning, and the second switching valve 37 At the same time as the state before washing, the reverse time setting timer is reset, and the accumulated time becomes zero. 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 to suppress the reverse number of times of voltage pressurization.

In the embodiment shown in FIG. 1, the connecting pipe 36 is connected to the middle part of the acidic ionized water derivation pipe 33 and the middle part of the alkaline ionized water derivation pipe 34 to simplify the piping configuration. As shown in the imaginary line of FIG. 1, the connecting pipe 36 is connected to the intermediate portion of the acidic ionized water derivation pipe 33 and the alkaline ionized water tank 50, or as shown in FIG. The connection pipe 36 is connected to an intermediate portion of the overflow pipe 45 disposed between the acidic ionized water tank 40 and the alkaline ionized water tank 50 having a sealed structure and an intermediate portion of the acidic ionized water lead-out pipe 33. When the connection pipe 36 is configured to be connected to the alkaline hot water tank 50 without intervening the alkaline hot water discharge pipe 34, the intermediate portion of the alkaline hot water discharge pipe 34 during the pipe cleaning operation of the apparatus. Alkaline hot water through the connection pipe 36 Since only acidic ionized water flows in the alkaline ionized water derivation pipe 34 over the entire length, it is possible to wash the entire alkaline ionized water derivation pipe 34 with acidic ionized water, thereby sufficiently securing the passage diameter of the alkaline ionized water derivation pipe 34. can do. The overflow pipe 45 shown in FIG. 2 is discharged from the excess acidic water in the acidic ionized water tank 40 and the acidic ionized water in the acidic ionized water tank 40, and the chlorine gas accumulated in the upper space of the copper tank 40. It has a function of inducing (larger specific gravity than air) to the alkaline ionized water tank 50, opening the upper end in the copper tank above the upper limit level L1 of the acidic ionized water tank 40 and simultaneously lowering the lower portion of the alkaline ionized water tank. It is opened in the copper tank under the liquid level of 50.
