Abstract: PURPOSE:To surely offer boiled hot water when a prescribed time elapses even if there is a variance due to the water temperature, etc., by determining a first heating start time for starting heating by the water quantity in a container. CONSTITUTION:By a setting means 9, a boiling end time is set as a set time T, and subtraction of a time counting means 11 is started by a time counting start means 10. In this case, a time setting means 7 determines a first heating start time T1 by the detected water quantity. When the remaining time becomes T1, a heating element 2 is conducted electrically and raises a liquid temperature in a container 1. Subsequently, when a liquid in the container 1 boils up, energizing of the heating element 2 is stopped, and it is left as it is until the remaining time comes to a second heating start time T2 for reboiling up the liquid in the container 1. When the time comes to T2, the energizing of the heating element is restarted until boiling-up is detected, and when boiling-up is detected, boiling-up is informed by stopping the electric conduction of the heating element 2 and operating an informing means 15. In such a way, hot water immediately after boiling-up can be obtained at the set time T.
