Description of the Related Art The above-mentioned ionic water generator has a pair of electrodes in an electrolyzer, and the raw water supplied to the electrolyzer is electrolyzed by passing a direct current between the electrodes, and the acidic water is applied to the anode side. It produces ion water and alkaline ion water on the cathode side. In this ionized water generator, scale such as hydroxide mainly composed of calcium ions in raw water is deposited and deposited on the surface of the cathode during electrolysis. This scale increases the electrical resistance between the electrodes, reduces the electrolysis efficiency and eventually renders electrolysis impossible. Therefore, as a countermeasure, a so-called reverse electric cleaning method is generally adopted in which the operation is performed by reversing the polarity of the current supplied to the electrode at regular intervals and the deposited scale is dissolved and removed in an acidic water atmosphere. .

In FIG. 2, electrolysis is performed during a time C during which a current having a predetermined polarity and a constant current value A flows, and acidic ionized water and alkaline ionized water are generated. On the other hand, as time passes, the scale described above is deposited on the cathode side. Therefore, in order to remove this scale, the electrode is reversely cleaned by flowing a current having a constant current value B having a reverse polarity and a constant value B for a certain period of time for a period D. When the polarity of the direct current with respect to the electrode is reversed, the cathode during electrolysis functions as an anode, and the deposited scale is placed in an acidic atmosphere near the anode. as a result,
Scales that are easily dissolved in an acidic atmosphere are removed by elution in acidic ionic water.

The current value that flows in the actual device varies depending on the water quality specification of the product, and ranges from several A to several tens A. The electrolysis time and the backwash time also differ depending on the product. For example, one hour for one hour electrolysis time for backwashing, one day for 30 minutes backwash for one hour,
Repeating electrolysis and backwashing every hour, from several days to 1
There are various methods such as one in which the reverse electric cleaning is repeated once in 0 days.

転の繰り返しは、電極寿命に大きな影響を与える。Next, the relationship between the backwashing and the deterioration of the electrodes will be described. Generally, a flat electrode is formed by plating a titanium substrate with platinum or a platinum / iridium alloy. If the electrolysis and the backwashing are continuously performed using such an electrode, ion water of a required quality cannot be obtained due to deterioration of the electrode plating portion.
The electrode life is usually about 1500 to 3000 hours for a normal product. The deterioration of the electrode plating part is specifically caused by the elution and peeling of the plating. It has been found that the elution of plating proceeds in proportion to the amount of electricity passed, but is accelerated by a rapid change in the current polarity. Further, peeling of plating occurs due to repetition of reversal of current polarity. Therefore, the repetition of the reversal of the current polarity by the backwashing for scale removal has a great effect on the electrode life.

The vertical axis represents the potential of the titanium surface, and the horizontal axis represents the pH of water in contact with titanium. This equilibrium diagram shows the form of titanium that is stably present under conditions determined by the combination of the titanium potential on the vertical axis and the pH of water on the horizontal axis. By the way, since a current of several A to several tens A flows through the anode at the time of electrolysis, its surface potential is always several V or more. The electrolyte water near the anode is more acidic than pH 5 due to hydrogen ions generated by electrolysis.

This is to enter the area where the titanium is shaded in FIG. 2, a state in which stably exist in the form of Ti ++ or Ti +++, which means that the chemical reaction tends state ionized . As a result, at the time of polarity switching, the titanium of the electrode reacts with hydrogen ions generated by the electrolysis of water, causing peeling of the plating at the boundary between the plating and the titanium substrate.

Flowing, while continuously generating ionized water by electrolyzing the raw water, removing the scale deposited on the cathode side of the electrode by reversing the polarity of the DC current to the electrode, wherein the ion water generator, When reversing the polarity of the DC current, the current value is once set to zero and held for a certain period of time, then the current value is gradually increased to a predetermined value of the opposite polarity over a certain period of time, and then the predetermined value is Shall be retained.

れる。In such means, when reversing the polarity of the direct current, the current value is first set to zero and held for a certain period of time to stop the generation of hydrogen ions at the anode, and at the same time, to close the anode. The high-concentration hydrogen ions generated up to this point are discharged out of the electrolytic cell together with the acidic ionized water, so that the hydrogen ion concentration near the anode can be reduced. Next, by gradually increasing the current value to a predetermined value of the opposite polarity over a certain period of time, hydroxide ions are generated near the anode, and the remaining hydrogen ions are neutralized. As a result, at the time of polarity switching, the pH near the anode changes from acidic to neutral,
Unlike the conventional case, the titanium of the electrode substrate does not easily become a state in which titanium hydride is easily generated, and peeling of the plated portion is suppressed.

返す。FIG. 1 is a current waveform diagram showing an embodiment of the present invention, in which a vertical axis represents a current value and a horizontal axis represents time. In FIG. 1, in this embodiment, when the polarity of the direct current flowing between the electrodes is reversed from + E (electrolysis) to −E (backwashing) or from −E to + E, the current value is temporarily reduced to zero. After maintaining the current value as it is for a predetermined time (in FIG. 1, non-energizing time a), the current value is applied for a predetermined time (in FIG.
The current value is gradually increased steplessly until E), and thereafter, the predetermined value is maintained for a predetermined time (the electrolysis time or the reverse power time c in FIG. 1). The current change up to this point is defined as one cycle, and the current is repeated while alternately switching the polarity between normal and reverse.

Further, thereafter, the direct current of the opposite polarity to be passed is gradually increased steplessly to generate hydroxide ions for neutralizing the hydrogen ions remaining near the anode.

防止される。As a result, after switching the polarity of the direct current, the pH near the anode changes from acidic to neutral, and in FIG. Does not pass through the route indicated by arrow A, but passes through the route indicated by arrow B. Accordingly, the surface potential of titanium at the time of switching the current polarity changes while avoiding the shaded region where Ti ++ or Ti +++ is stable, and the generation of titanium hydroxide by the reaction between titanium and hydrogen ions. Is prevented, and peeling of plating is suppressed. In addition, the direct current having the opposite polarity is not switched to a predetermined value at a stroke as in the conventional case, but is gradually increased steplessly over a predetermined time, so that the electric shock damage given to the plating portion is reduced. It is small and elution of plating is prevented.

That is, the waveform of the DC current flowing between the electrodes is made symmetric with respect to the polarity. According to such an energization control method, the reverse-current cleaning can be performed under the same conditions as the electrolysis,
