WATER DISPENSER

摘要

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.

主权项

1. A water dispenser comprising:
a hot water tank configured to store high temperature drinking water to be discharged to outside of the water dispenser; a heater configured to heat drinking water in the hot water tank transferred from a replaceable raw water container; and a control device configured to carry out a sterilization operation in which:
a valve control configured to switch valves so as to form a circulation route through which drinking water flowing out of the hot water tank can be circulated through predetermined portions of a piping system back to the hot water tank; anda pump control configured to drive a pump so as to circulate the drinking water in the hot water tank through the circulation route; are combined, wherein the control device is configured, when the water dispenser is turned on, to carry out a basic reservation control configured to automatically start a timer control of the sterilization operation according to a predetermined routine; and if an input of a predetermined signal via a switch operation by a user is confirmed, the control device is configured:if the input is a first input after the water dispenser has been turned on,to carry out: the sterilization operation; an energy saving operation in which the heater is maintained off after the completion of the sterilization operation, and turned on when a prescribed period of time has elapsed since the input; and a reservation control configured to update reserved times determined by the timer control according to the predetermined routine based on a reference time at which the input is made; andif the input is a second or subsequent input after the water dispenser is turned on, to compare an elapsed time since an input of the predetermined signal which initiated a last sterilization operation until said second or subsequent input with a threshold value; andto carry out the sterilization operation, the energy saving operation, and the reservation control, if a relation: elapsed time>threshold value is satisfied; and to carry out the energy saving operation without performing the sterilization operation and the reservation control, if a relation: elapsed time≦threshold value is satisfied.
