を特徴とする電気湯沸かし器。 It has a container 2 that stores water, a heating element 4 that heats and boils the water in the container 2, and a control means 7 that detects boiling and controls energization to the heating element 4 to maintain a warm state. In the electric water heater, the amount of water in the container 2 is detected by an ultrasonic sensor 9 provided on the bottom of the container 2, and the ultrasonic sensor 9 is connected to the control means 7, and the control means 7 is further provided with a timer setting means 19. When the timer is connected and the timer is set, calculate the time it takes for the water in container 2 to boil and the time it takes for the hot water to reach the keep-warm temperature based on the detected water volume, and calculate the time from the timer set time until the keep-warm temperature is reached. The control means 7 subtracts the time, starts energizing the heating element 4 after the subtracted time has elapsed from the timer set time, and controls the hot water to be kept warm after the timer set time elapses. Electric water heater.
