1. A control apparatus for controlling a continuous electrolytic ion water producing apparatus which includes an electrolytic cell, a pair of negative and positive electrodes accommodated in said electrolytic cell, a water pipe line for introducing water to said electrolytic cell and a filter cartridge disposed in said water pipe line for removing residual chlorine from water passing through said water pipe line, said control apparatus comprising:

  • a flow rate sensor disposed in the water pipe line for detecting flow rate of water passing through the water pipe line;

    a power source circuit for applying a DC voltage between the negative and positive electrodes;

    a range change-over switch for selecting said DC voltage;

    a power source switch for said power source circuit; and

    control means for judging whether or not an electrolyzing operation should be performed on the basis of the flow rate detected by said flow rate sensor and said selected DC voltage and for controlling said power source switch in accordance with the judgement, said control means comprising water flow totalizing means for determining a cumulative amount of water passed through the water pipe line, and filter life judging means for judging the remaining useful service life of the filter cartridge from said cumulative amount of water.
