沸器。A first thermal switch in contact with the outer surface of the container at a position above the heater in a device that heats the outer layer of the lower end of a container containing a liquid such as water with a heater to boil water;
A second thermal switch that is in contact with the outer surface of the container at a position lower than the heater is connected in parallel, and the operating temperatures of both thermal switches are made different, so that the heater is energized by a parallel circuit of both thermal switches. An electric water heater characterized in that it is configured to control and raise the temperature to a predetermined temperature regardless of the water level.
