Title: Apparatus for generating alkali ion water

Abstract: An apparatus for generating alkali ion water includes an electrolytic cell. At least two electrodes are disposed in the electrolytic cell. A diaphragm disposed in the electrolytic cell extends between the electrodes. A dc voltage is supplied to the electrodes. A mean value of the dc voltage is varied at a given inclination. A first detecting device operates to detect an ac current and generate a signal representative thereof. The dc voltage is derived from the ac current. A second detecting device operates to detect the mean value of the dc voltage in response to the signal generated by the first detecting device. A third detecting device operates to detect an inclination in a variation in the mean value of the dc voltage in response to the mean value of the dc voltage which is detected by the second detecting device. The mean value of the dc voltage is controlled in response to the inclination detected by the third detecting device.
