Hereinafter, the operation of the water purifier having a sterilizing device according to the present invention configured as described above and its operation mode will be described in detail.

For example, microorganisms or bacteria grow on the water tank 22, especially on the inner surface of the water tank during repeated use of the water purifier or as time passes. At this time, the controller 52 operates the sterilizer 40 by a periodic execution program input thereto or by a user operating the on / off switch 58 arbitrarily.

When the sterilization device 40 is operated by the controller 54, power is first supplied to the warning light 48 to blink or light, thereby visually warning the user or operator that the sterilization operation is in progress. The lighting of this warning light 48 continues until the sterilization operation is completed, and is set and controlled by the timer 56.

At the same time, the controller 54 powers and operates the silver ion generator 42 connected thereto. That is, supplying a current of, for example, about 20 to 40V to the silver electrode 46 by the controller 54 causes silver ions to be generated at each of these silver electrodes 46. This silver ion generation operation is controlled by a timer 56 installed in the controller 54, the operation time of which may be set, for example, about 15 to 30 minutes, which is the controller 54 or the timer 56. It is set and adjusted by

Next, the controller 54 opens the drain valve 52 provided in the drainage column 50 to discharge the purified water remaining in the water tank 22. Simultaneously with this drainage operation, the silver ion water generated in the silver ion generator 42 passes through the discharge port 44b of the housing 44, through the inlet line 10, and also through the ultrafiltration membrane filter 16. It is fed into the water tank 22 through. As a result, the purified water and silver ion water present in the existing water tank 22 are replaced. If such replacement is continued and the water tank 22 is completely filled with silver ionized water, the controller 54 or the timer 56 closes the drain valve 52 to allow the silver ionized water to stagnate in the water tank 22.

As such, when the silver ionized water is charged in the water tank 22, the controller 54 or the timer 56 stops the operation of the silver ion generator 44. By the silver ion water remaining in the water tank 22, microorganisms or bacteria that adhere to the inner surface of the water tank 22, especially the water tank 22, proliferate or parasitic are sterilized. The residence time in the bath 22 of silver ionized water is set by the controller 54 or the LCD or timer 56 at a sufficient time of about 10 to 30 minutes so that the microorganism or bacteria can be completely sterilized.

Thereafter, the controller 54 or the timer 56 opens the drain valve 52 again to discharge the silver ion water used for the sterilization treatment through the drain line 50. Such drainage is set and executed by the controller 54 or the timer 56 until the water stored in the tank is completely discharged so that silver ions do not remain in the tank 22. Of course, afterwards or at the same time as the discharge of the treated water, the purified water is introduced into the tank and filled, thereby starting to prepare the normal water purifier state.

When the silver ionized water in the water tank 22 is completely discharged, the controller 54 or the timer 56 closes the drain valve 52. The controller 54 or timer 56 then turns off the warning light 48 to inform the user or operator that the water purifier has returned to its normal state. Of course, in this case, the new purified water is filled in the water tank 22, so that the user or worker can drink or use hot or cold water by using the valves 30a and 32a of the discharge lines 30 and 32.
