Controlling apparatus for continuous electrolytic ion water producing apparatus
First Claim
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.

Abstract
A control apparatus which can control a continuous electrolytic ion water producing apparatus so that determination and indication of energization and electrolyzing capacity of an electrolytic cell and determination and indication of a life of a filter cartridge are performed appropriately. A control unit connected to a power source circuit of the electrolytic cell includes an electrolysis judging device which judges, based on a signal of a flow rate sensor and a signal of a range change-over switch whether or not an electrolyzing operation should be performed. When the electrolyzing judging device judges that an electrolyzing operation should be performed, a power source switch is turned on to cause the power source circuit to energize the electrolytic cell to perform an electrolyzing operation. On the contrary when it is judged that an electrolyzing operation should not be performed, the electrolysis judging device turns off the power source switch to put the electrolytic cell into a deenergized condition.
