[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system of a continuous electrolytic ion water generator for electrolyzing tap water or the like to continuously generate alkaline ionized water and acidic water. Regarding the notification method of.

[0002]

2. Description of the Related Art A continuous electrolytic ionized water generator supplies drinking water to an electrolytic cell, applies a DC voltage between an anode and a cathode in the electrolytic cell, electrolyzes the drinking water and continuously supplies it. To do. There is a problem that impurities contained in water are deposited on the surface of the electrode to be electrolyzed, and the electrolysis becomes gradually difficult. Therefore, in order to remove impurities on the surface of the electrode, the voltage applied to the electrode is reversed with respect to the polarity in the electrolysis mode and applied for a certain period of time. By applying an inverted voltage, impurities on the electrode surface are eluted and removed to clean the electrode surface.

In the above-mentioned conventional ionized water generator, when used for a long time, the electrode of the electrolytic cell deteriorates and the electrolysis capacity becomes weak. It was judged and exchanged.

However, such maintenance of the electrolytic cell is time-consuming and requires the user to check the usage time.

The present invention has been made in order to solve the above-mentioned problems, and when the duration of electrolysis and cleaning reaches a predetermined time, a warning is given that it is time to replace the electrolytic electrode, and the user It is intended to reduce the burden.

[0006]

The method for informing the electrolytic electrode replacement time of an ionized water generator of the present invention comprises a process of electrolyzing the supplied water by an electrode for generating ionized water, and the electrolysis at a predetermined time. When the voltage is reached, the process of inverting and applying the voltage to wash the electrode, the process of measuring and integrating and storing the electrolysis and cleaning time, and the integration time of the electrolysis and cleaning time have reached a predetermined time. Sometimes, it comprises a process of issuing a warning to replace the electrolytic electrode.

[0007]

When water is supplied to the electrolytic cell, the control circuit operates so as to apply a DC voltage of a predetermined polarity to the electrodes inside the electrolytic cell. When the generation of ionized water by electrolysis reaches a certain time, the water supply is stopped, whereby the control circuit operates to reverse the polarity of the DC voltage. Further, after the inversion voltage is applied for a predetermined time, the polarity is restored. This electrolysis time and cleaning time are measured,
Remembered. Further, the electrolysis and cleaning are repeated, and when the accumulated time reaches a predetermined time, the user is notified that it is time to replace the electrolytic electrode.

The measurement of 'is started (step S-1). Electrolysis time t '
Is integrated and the integrated time x is compared with a predetermined time T (step S-2). If x is smaller than T, the process returns to step S-1 to continue the electrolysis and the electrolysis time measurement. If x becomes larger than T, a voltage inverted from the electrolysis voltage is applied when the electrolysis operation is stopped, and the application time s of the inversion voltage is measured (step S-3). Where T
And the sum of s are added to the result M stored up to the previous time and stored as M (step S-4). Then, the sum of T and s is reset (step S-5). M is compared with the predetermined time K (step S-6). If M is less than the predetermined time K, the process returns to step S-1 and M is K.
