To do. The raw water introduced from the faucet 2 is subjected to removal of residual chlorine, trihalomethane, musty odor, general bacteria, and other impurities in the raw water by the water purification unit 4, and after passing through the flow rate detection means 5, calcium glycerophosphate and lactic acid After calcium or the like is dissolved and treated with water that is easily electrolyzed, it is introduced into the electrolytic cell 7.

At the same time, a predetermined signal is sent from the controller 16 to the movable valve 12 so that the valve opens and stops at a predetermined valve opening.

Now, after passing water, the controller 16 reads the output signal from the flow rate detection means 5, and determines that this state is underwater if the flow level flowing through the alkaline ionized water device body per unit time exceeds a certain amount. At this time, the controller 16 supplies predetermined electric power to the electrolytic cell 7 under the electrolysis conditions corresponding to the water quality mode and pH intensity that have already been selected.

In the water purification mode, power is not supplied to the electrode plates 9 and 10, and purified water is discharged from the water discharge pipe 13 and drainage is discharged from the drain pipe 11. Thereafter, when the flow rate level flowing through the alkaline ionized water body 3 per unit time falls below a certain amount, this state is determined to be water stop, the supply of power to the electrolytic cell 7 is terminated, and the movable valve 12 from the controller 16 is terminated. A predetermined signal is sent to the valve so that the valve closes and stops at the water stop position.

FIG. 1 is a configuration diagram of an alkaline ionized water device according to Embodiment 1 of the present invention. In FIG. 1, the same reference numerals as those used in the description of the prior art are basically the same in the first embodiment, and thus the detailed description will be omitted for the prior art.

  In FIG. 1, 1 is a raw water pipe such as tap water, 2 is a faucet, 3 is an alkali ion water conditioner body, 4 is a water purification unit, 5 is a flow rate detection means, 6 is a calcium supply unit, 7 is an electrolytic cell, 8 Is a diaphragm, 9 and 10 are electrode plates, 11 is a drain pipe, 12 is a movable valve, 13 is a water discharge pipe, 14 is a power-on plug, 15 is a power supply section, 16 is a controller, 17 is an operation display section, and 18 is a controller. A movable valve that is one of 16 constituent parts and that sends a signal to the movable valve 12 to adjust the opening degree of the valve in accordance with the blocked water state in the flow rate detection means 5 and the water quality setting state in the operation display unit 17. Adjustment means.

  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. The user selects a desired water quality mode such as alkaline ion water generation mode, acidic ion water generation mode, or water purification mode and pH intensity by pressing a predetermined button on the operation display unit 17, opens the faucet 2, and passes water. To do. The raw water introduced from the faucet 2 is subjected to removal of residual chlorine, trihalomethane, musty odor, general bacteria, and other impurities in the raw water by the water purification unit 4, and after passing through the flow rate detection means 5, calcium glycerophosphate and lactic acid 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 14, and a DC voltage / current necessary for electrolysis is generated by the transformer in the power supply unit 15 and the control DC power supply, and the electrode plate 9 of the electrolytic cell 7 is connected via the controller 16. 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. At the same time, a predetermined signal is sent from the movable valve adjusting means 18 to the movable valve 12 to operate in the direction in which the valve opens, and stops at the position of the predetermined valve opening.

  Now, after passing water, the controller 16 reads the output signal from the flow rate detection means 5, and determines that this state is underwater when the flow rate level flowing through the alkaline ionized water device body per unit time exceeds a certain amount. At this time, the controller 16 supplies predetermined electric power to the electrolytic cell 7 under the electrolysis conditions corresponding to the water quality mode and pH intensity that have already been selected.

However, at the initial stage of water flow, the electrolysis is performed before the power supply to the electrode plates 9 and 10 is started. Since untreated water is discharged and mixed with electrolyzed water at a predetermined valve opening thereafter, the pH value of alkaline ionized water or acidic ionized water may not reach a desired value. However, if the configuration of the first embodiment is provided, the pH value of the sampled water is adjusted by mixing the water that is not electrolyzed immediately after the start of water flow with water having a desired pH value or more. It can be set to a desired value.

FIG. 3 is a graph of a change in pH value of water for each fixed amount of water sampled when weak electrolytic strength is switched to strong electrolytic strength while passing through the alkaline ionized water device according to Embodiment 2 of the present invention. From this graph, it can be seen that the pH value has reached the desired value when the electrolysis strength is switched. On the other hand, FIG. 7 is a graph of the change in pH value of water for each fixed amount of water sampled when the weak electrolytic strength is switched to the strong electrolytic strength while passing through a conventional alkaline ionized water device. From this graph, it can be seen that the pH value does not reach the desired value when the electrolysis strength is switched.
