Filed: 1989-04-21
Abstract: PURPOSE:To prevent a user from erroneously use the water having low or high temperature by detecting the boiling of the water in a container and prohibiting the supply of the hot water until the water in the container boils. CONSTITUTION:When operation starts, a hot water supply-prohibiting means 7 prohibits the supply of hot water, and a heating means 2 heats the water in a container 1. Then, a boiling detecting means 4 judges if the water in the container 1 boils or not, and when boiling does not occur, heating is continued to boiling, while if boiling is judged, the prohibition by the hot water supply- prohibiting means 7 is released, and a user can use the hot water supplied from a hot water supply means 5. Then the temperature is kept constant by a control mean 6 and the temperature of the water in the container 1 is monitored by a temperature detecting means 3, and if the water temperature lowers, the supply of hot water is prohibited again, and the rise of temperature to boiling is carried out.
