Ion concentration setting apparatus for ionic water.

摘要

An apparatus for setting the ion concentration in an ionic water generator which separates a drink water between an alkaline ionic water and an acidic ionic water by applying a DC voltage between the electrodes in an electrolytic cell which are partitioned by an ion-exchange membrane, the apparatus comprising a device for measuring the voltage drop between specific portions which lead into the electrolytic cell which is caused when a reference voltage is applied, and a calculator for calculating the voltage Vx which is applied to the electrolytic cell to adjust the ion concentration to a desired value from the proportion k of the voltage drop between the specific portions caused by the application of the reference voltage to a water being examined to the reference voltage drop between the specific portions caused by the application of the reference voltage to reference water and a set voltage Vn which corresponds to the desired ion concentration on the basis of the following equation: Vx = k x Vn
