Abstract
In order to heat and warm only the amount of water required in immediate future and to reduce a power consumption by avoiding warming of unnecessary water, a main body provided with a water storage container and a water heating container can be attached and detached and a water heating amount or a water warming amount to be heated at one time is reduced and divided, thus, power consumption during warming is reduced. Furthermore, since the water storage container is provided independently, water supply can be carried out conveniently regardless of the state of the water-heating container. Water supply to the water-heating container is carried out automatically using a water amount sensor, hence no operation by a user is required.
