The drain pipe 13 is provided with a drain electromagnetic valve 11. Note that the drain electromagnetic valve 11 may be opened and closed by driving an electric motor.

  The cartridge 4 includes activated carbon that absorbs residual chlorine in the raw water supplied from the water supply pipe 1 and a hollow paper membrane that removes general bacteria and impurities. The flow sensor 6 confirms water flow and gives a control instruction to the control unit 15 described later. The calcium supply unit 5 increases conductivity by administering calcium ions such as calcium glycerophosphate and calcium lactate into raw water.

The electrolytic cell 7 includes electrode plates 9 and 10 in each electrode chamber formed by dividing the inside of the cell by the diaphragm 8. Then, water used in this electrode chamber (alkaline ion water when the electrode plate 9 is a cathode, acid ion water when the electrode plate 9 is an anode) is discharged into the electrode chamber on the side provided with one electrode plate 9. The discharge pipe for connecting is connected. On the other hand, the electrode chamber on the side provided with the other electrode plate 10 has a non-used water generated in this electrode chamber (acid ion water when the electrode plate 10 is an anode, The drainage pipe 13 for discharging (alkaline ion water) is connected, and drainage is performed by opening the drainage electromagnetic valve 11.

The power supply section 16 is provided with a power-on plug 17b connected to a commercial AC power supply.

  The operation display notification unit 18 includes an operation unit 18a and a display notification unit 18b. The operation part 18a selects and switches among the alkaline ionized water generation mode, the purified water mode, and the acidic ionized water generation mode. When one of the three modes is selected by the operation unit 18a, the selected mode is displayed on the display notification unit 18b. Further, when water is passed after mode selection, the control unit 15 sets the polarity (that is, which of alkaline ion water generation and acidic ion water generation is generated from the electrode chamber on the side provided with one electrode plate 9) and the water flow state. Is determined, and the water selected in any mode after the electrolysis in the electrolytic cell 7 is discharged. In the case of alkaline ionized water, each mode of “beginning of drinking”, “accustomed to drinking”, “everyday drinking”, and “strong” can be selected in order from the weaker one by the pH adjustment button of the operation unit 18a. These operating states are displayed by an LED or LCD, and a notification sound is generated as necessary.

  The control unit 15 includes an MPU 15a (Micro Processing Unit), a polarity switching unit 15b, and an electrolytic voltage switching unit 15c. The MPU 15a obtains a control instruction from the flow sensor 6, the water purifier sensor 14, and the operation unit 18a, and performs arithmetic processing. Then, if necessary, the drainage electromagnetic valve 11 and the display unit 18b are instructed to operate. The polarity switching unit 15b switches the polarity in accordance with an operation instruction from the MPU 15a. The electrolytic voltage switching unit 15c changes the average voltage applied to the electrolytic cell 7 by pulse-modulating the direct-current voltage output from the control power supply unit 16 in accordance with an operation instruction from the MPU 15a. The pH concentration of the alkaline ionized water can be changed according to the average voltage pulse-modulated by the electrolytic voltage switching unit 15c.

  Below, the fundamental operation | movement in the case of producing | generating alkali ion water is demonstrated. First, the power supply plug 17b is connected to a commercial power supply, and power is supplied to the control unit 15. At this time, since the display in the display notification unit 18b is in an initial value state (for example, “purified water mode”), when an arbitrary setting is desired (for example, “alkaline ion water generation mode”). The alkaline ion water generation mode is selected and set by the operation display notification unit 18b. Then, the raw water supplied from the water supply pipe 1 removes the odor of residual chlorine and impurities such as general bacteria in the raw water with the cartridge 4, and the calcium supply unit 5 dissolves calcium glycerophosphate and the like and is processed into water that is easily electrolyzed. The After this treatment, water is supplied to the electrolytic cell 7 through the flow sensor 6. When raw water is passed through the main casing 3, it is detected by the flow sensor 6, and the controller 15 applies a voltage to the electrodes 9 and 10 of the electrolytic cell 7. At this time, when the drainage solenoid valve 11 is opened and the alkaline ionized water generation mode is selected, the acidic ionized water is discharged from the drainpipe 13 when the acidic ionized water generation mode is selected. Is done. In the water purification mode, the electromagnetic valve 11 for drainage is closed to cut the drainage. When the supply from the water supply pipe 1 is stopped and the water is stopped, the control unit 15 determines that the water is stopped from the detection signal of the flow rate sensor 6, and the voltage application from the control unit 15 to the electrodes 9 and 10 is stopped and the electrolyzed water is stopped. Generation of.
