For example, when the unflowing water setting time is set to 10 hours, the setting cycle is set to 3 hours, and the driving setting time is set to 5 minutes, the controller 62 controls the water in the water tank 4 for 10 hours. If the water is not discharged, the UV sterilization unit 6 may be driven for 5 minutes at 3 hour intervals and stopped after the accumulated time exceeds 10 hours, and the water tank (4 before the accumulated time reaches 10 hours). When water of the water) is discharged, the ultraviolet sterilization unit 6 is driven to sterilize the water tank 4 when the water is discharged, so that the ultraviolet sterilization unit 6 is not driven at an interval of 3 hours. On the other hand, if the water is discharged from the water tank 4 during the control of driving the ultraviolet sterilization unit 6 for 5 minutes at a three-hour interval and stopping the control unit 62, the ultraviolet sterilization unit 6 at the time of water extraction Since it can be driven to sterilize the water tank 4, it is possible to reset the accumulated time to zero without driving the ultraviolet sterilization unit 6 every three hours.

4 is a flowchart of another embodiment of a method of operating a water purifier according to the present invention.

The water extraction step (S1) (S2 ') (S3) (S4) (S5) (S6) is to drive the ultraviolet sterilization unit 6 first, and then open the water outlet valve 25 later, the water extraction step ( S1, S2 ', S3, S4, S5, and S6 will be described in detail.

When the user inputs the water output to the water output input unit 60, the controller 62 first drives the ultraviolet sterilization unit 6 without opening the water outlet valve 25. (S1) (S2 ')

When the water discharging valve 25 is not opened as described above and the ultraviolet sterilizing unit 6 is driven, the water in the water tank 4 is sterilized gradually by the ultraviolet rays irradiated from the ultraviolet sterilizing unit 6.

The controller 62 opens the water discharge valve 25 when the air set time has elapsed after the ultraviolet sterilization unit 6 starts to be driven.

The water in the water tank 4 is sufficiently sterilized by the ultraviolet sterilization unit 6 in a state in which water from the water tank 4 cannot be discharged to the outside of the water tank 4, and when the water outlet valve 25 is opened, the water is discharged by the ultraviolet sterilization unit 6. It is discharged to the outside in a sufficiently sterilized state.

 On the other hand, when the user no longer wants to withdraw the water in the water tank 4, the user can input the withdrawal stop to the water extraction input unit 60, the control unit 62 in accordance with the user's input water outlet valve 25 (S3) (S4)

The control unit 62 closes the water outlet valve 25 first as the water purifier operation method of the embodiment of the present invention when the water outlet valve 25 is closed, and then additionally drives the ultraviolet sterilization unit 6 when the additional drive set time elapses.
