CONSTITUTION: A heater 9 is provided in an outer case 1 to heat the inside of an outer water tank 2 and an inner water tank 11 is provided with a heating area 13 formed between the tank and the outer water tank 2 to heat water in the heating area 13 with the heater 9 thereby enabling the shortening of rising-time in heating water up to a usable temperature. Moreover, the inner water tank 11 is made free to load on or unload from a broad mouthed outer water tank to facilitate the cleaning of the outer and inner water tanks by taking out the inner water tank.</p> |
