Abstract

A water dispenser is provided in which a when turned on, timer control of a sterilization operation is automatically started. If an initial input of a predetermined signal by a user is confirmed, after the sterilization operation, an energy saving operation in which the heater is maintained off for a limited time; and a reservation control in which reserved times determined by the timer control are updated based on the time when the input is made; are carried out. If a second or subsequent input is confirmed, the elapsed time since the last sterilization operation until the second or subsequent input is compared with a threshold. If the elapsed time is longer than the threshold, the sterilization operation, the energy saving operation, and the reservation control are carried out. If not, the energy saving operation is carried out without performing the sterilization operation and the reservation control.
