It is. In FIG. 1, the same reference numerals as those used in the description of the conventional alkaline ionized water device are basically the same in the alkaline ionized water device of the first embodiment, and the detailed description thereof will be omitted. I will omit the explanation for the ion water conditioner.

The controller 15 is configured as a functional unit that reads a program into the CPU and functions.

  Next, the operation | movement at the time of producing | generating the alkali ion water is demonstrated about the alkali ion water conditioner 3 of this invention comprised as mentioned above below. By pressing a predetermined button on the operation display unit 16, the user selects a desired water quality mode such as an alkaline ionized water generating mode, an acidic ionized water generating mode, or a purified water mode, and further selects the pH intensity, and the faucet Open 2 and start water flow.

The raw water introduced from the faucet 2 removes residual chlorine, trihalomethane, musty odor, general bacteria, and other impurities in the raw water in the water purification unit 4, and after passing through the flow rate detection means 5, calcium glycerophosphate and lactic acid in the calcium supply unit 6. After calcium or the like is dissolved and treated with water that is easily electrolyzed, it is introduced into the electrolytic cell 7. On the other hand, 100 VAC is supplied from the power-on plug 13, and a DC voltage / current necessary for electrolysis is generated by the transformer in the power supply unit 14 and the control DC power supply, and the electrode plate 9 of the electrolytic cell 7 is connected via the controller 15. And 10 are supplied with electric power necessary for electrolysis. At this time, if an electrode plate to which a positive voltage is applied relatively is an anode and an electrode plate to which a negative voltage is applied is a cathode, an anode chamber and a cathode chamber partitioned by a diaphragm 8 are formed in the electrolytic cell 7. In the alkaline ion water generation mode, the electrode plate 10 serves as an anode and the electrode plate 9 serves as a cathode. In the acidic ion water generation mode, the electrode plate 9 serves as an anode and the electrode plate 10 serves as a cathode.

  Now, after passing water, the controller 15 reads the output signal from the flow rate detection means 5 and determines that this state is underwater when the flow level per unit time flowing through the alkaline ionized water body 3 exceeds a certain amount. At this time, the controller 15 supplies predetermined electric power to the electrolytic cell 7 based on the electrolysis conditions corresponding to the water quality mode and the pH intensity that have already been selected.
