Abstract

A controlling apparatus which can control a continuous electrolytic ion water producing apparatus so that an excess current when the electrolyzing strength is not adjusted appropriately can be prevented with certainty and harmless electrolytic ion water can be obtained continuously from the continuous electrolytic ion water producing apparatus. When water flows through the electrolytic cell, it is energized by a power source circuit to electrolyze the water to obtain electrolytic ion water. When a range change-over switch is manually operated, a dc voltage of the power source circuit is controlled in response to the range change-over switch by a control unit and a switching regulator to produce an electrolyzing voltage corresponding to the operated position of the range change-over switch. The water is thus electrolyzed with an electrolyzing strength of the electrolyzing voltage. During the electrolyzing operation, the electrolytic current is always detected by a current sensor, and when it exceeds a preset value and an excess current is judged, the pulse width is decreased to automatically decrease the electrolyzing voltage and hence the electrolyzing capacity.
