As described above, according to the present invention,
There is no need to manually open and close the tap faucet, and even if it is always open, the water shutoff valve will close unless the flow switch provided on the control panel of the ion water generator body is turned on. Since it is held in the open position, no water flow occurs. Even if the flow switch 5 is ON, if the water pressure detected by the water pressure sensor is lower than a predetermined value, or if the water temperature detected by the water temperature sensor is higher than the predetermined value, the output from the control panel is output. Since the water shutoff valve is closed by the signal, usability is greatly improved. Furthermore, when the flow switch is turned on and the water shutoff valve opens, when the flow switch is inadvertently operated during electrolysis by the electrolytic cell, or the water pressure sensor lowers the water pressure below a predetermined value, When it rises and becomes higher than the predetermined value, the water shutoff valve is immediately closed to stop the electrolysis action, and the display on the display section is also cleared to prevent damage to the main body of the ionized water generator.
