Then, when the water level in the water tank 1 reaches the predetermined water level, the ball tap 9 operates to stop the supply of tap water. Next, an appropriate amount of salt water is prepared in the salt water tank 3. Subsequently, the solenoid valve E of the water supply piping system 5
V1 and EV2 are opened, and the solenoid valve EV of the drainage piping system 6 is opened.
3. Only the EV 8 is opened to start the electric pump 2. No voltage is applied to the electrode plates 20a and 20b of the electrolysis apparatus 4. Then, tap water supplied from the water supply branch pipes 5a to 5d into the electrolysis device 4 is discharged from the drainage branch pipes 6a to 6d as it is, and flows out from the branch pipes 6e and 6j to the drain discharge pipe 22. At this time, the stagnant acidic water and alkaline water are discharged together with tap water.

るのにも役立つ。Next, the process shifts to a process for producing acidic water and alkaline water. In this case, the solenoid valves EV3, EV3,
The EV 8 is closed, the solenoid valves EV4 and EV7 are opened, and a voltage is applied to the electrode plates 20a and 20b of the electrolysis device 4 to start production of acidic water and alkaline water. Tap water to which the salt water is added and introduced into the electrolysis device 4 is easily conducted since the electric resistance between the electrode plates 20a and 20b is small, and sodium ion, hydrogen ion and chlorine ion, and hydroxyl ion by electrolysis are provided. Occurs quickly. The sodium ions are exchanged with the hydroxyl ions of the ion exchange membrane 18, and the hydrogen ions are on the electrode plate 20b side to which a negative voltage is applied, and the chloride ions and hydroxyl ions are exchanged on the electrode plate 20a side to which a positive voltage is applied. Gravitate. As a result, the water discharged from the drainage branch pipes 6a and 6c becomes acidic water, and flows into the acidic water tank 24 through the branch pipe 6f, the solenoid valve EV4, and the acidic water discharge pipe 23. The water discharged from the drainage branch pipes 6b and 6d becomes alkaline water, and flows into the alkaline water tank 26 through the branch pipe 6i, the solenoid valve EV7, and the alkaline water discharge pipe 25. In this case, the network 19 scatters the water flow in the electrolysis device 4 and allows more tap water to come into contact with the surface of the ion exchange membrane 18, so that the ion exchange efficiency can be suitably increased. Further, the mesh body 19 also serves to reinforce the ion exchange membrane 18 having low mechanical strength.

る。When the electrolysis apparatus 4 is operated for more than a predetermined time, crystals are formed on the electrode plates 20a and 20b and so-called electrolytic corrosion occurs, so that the ion exchange rate is reduced. Therefore, after operation for a predetermined time, the polarity of the applied voltage is reversed as a measure against electrolytic corrosion of the electrode plates 20a and 20b of the electrolysis device 4. At this time, first, a reversal initial operation is performed to purge the acidic water and the alkaline water remaining in each pipe. This reversal initial operation may be performed in the same manner as the above-described initial operation at the start of the operation of the apparatus. Thus, the crystal is separated from the surface of the electrode plate, and a clean surface of the electrode plate is obtained. The crystal separated from the electrode plate is discharged to the outside through the drain discharge pipe 22.

5, EV6 is opened, and the electrode plates 20a, 20b of the electrolytic device 4 are opened.
Then, a voltage having a polarity opposite to that of the above-described production operation is applied to start production of ionized water. The water discharged from the drainage branch pipes 6a and 6c becomes alkaline water, and flows into the alkaline water tank 26 through the branch pipe 6h, the solenoid valve EV6, and the alkaline water discharge pipe 25. The water discharged from the drainage branch pipes 6b and 6d becomes acidic water, and flows into the acidic water tank 24 through the branch pipe 6g, the solenoid valve EV5, and the acidic water discharge pipe 23.
