Abstract

Abstract A controlling apparatus which can control a continuous electrolytic ion water producing apparatus so that determination and indication of energization and an electrolyzing capacity of an electrolytic cell and determination and indication of a life of a filter cartridge are performed appropriately. A control unit (40) connected to a power source circuit (10) of the electrolytic cell (5) includes electrolysis judging means (42) which judges it from a signal of a flow rate sensor (4) and a signal of a range change-over switch (28) whether or not an electrolyzing operation should be performed. When the electrolyzing judging means judges that an electrolyzing operation should be performed, a power source switch (17) 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 means turns off the power source switch to put the electrolytic cell into a deenergized condition.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 180 words
A controlling apparatus for a continuous electrolytic ion water producing apparatus which includes an electrolytic cell, a pair of negative and positive electrodes accommodated in said electrolytic cell and a water pipe line for introducing water to said electrolytic cell, comprising: a filter cartridge disposed in said water pipe line for removing residual chlorine in water passing through said water pipe line; a flow rate sensor disposed in said water pipe line for detecting a flow rate of water passing through said water pipe line; a power source circuit for applying a dc voltage between said negative and positive electrodes; a range change-over switch for adjusting the electrolyzing strength of said electrolytic cell; a power source switch for said power source circuit; and a control unit for judging whether or not an electrolyzing operation should be performed in response to a flow rate detected by said flow rate sensor and an electrolyzing strength of said electrolytic cell, which Is determined by an operated position of said range change-over switch, and controlling said power source switch in accordance with the judgment.
Claim 2
Dependent Claim 85 words
A controlling apparatus for a continuous electrolytic ion water producing apparatus according to claim 1, wherein said control unit includes water passage amount calculating means for accumulating a flow rate to calculate a cumulative water passage amount when water flows through said water pipe line, and filter life judging means for judging the life of said filter cartridge from the accumulated water passage amount and indicating, when it is detected that the life of the said filter cartridge has expired, such expiration of the life.
Claim 3
Dependent Claim 60 words
A controlling apparatus for a continuous electrolytic ion water producing apparatus according to claim 1, wherein said control unit includes electrolyzing capacity judging means for judging, when water flows through said water pipe line, an electrolyzing capacity from a flow rate detected by said flow rate sensor and indicating whether the flow rate is excessively high, excessively low or appropriate.
Claim 4
Dependent Claim 44 words
A controlling apparatus for a continuous electrolytic ion water producing apparatus according to claim 2, wherein said filter cartridge includes a reset switch which resets accumulation of the water passage amount by said water passage amount calculating means when a filter thereof is exchanged.
