る電気湯沸かし器。 A container 2 that stores water, a heating element 4 that heats and boils the water in the container 2, and a temperature detection element 6 that detects boiling and controls power supply to the heating element 4 to maintain a warm state. In an electric water heater, the temperature can be controlled by specifying either a normal heat retention temperature or a predetermined heat retention temperature between 100 and 80°C, and the control means 7 is further provided with a timer function, and the control means 7 is equipped with a temperature detection function. The element 6, the timer time setting means 21, the timer time display element 19, the heat retention state switching means 22, the heat retention state display means 23, the notification means 24, and the ultrasonic sensor 9 provided on the bottom surface of the container 2. When the timer time A is set by the timer time setting means 21, the time A is displayed on the timer time display element 19, and one of the heat retention states specified by the heat retention state switching means 22 is inputted. The state is displayed on the heat preservation state display means 23, the amount of water in the container 2 is detected using the ultrasonic sensor 9, and the time B until the water in the container 2 boils and the boiled water are specified above based on the detected amount of water. Calculate the time C until the heat retention state is achieved, subtract the calculated time B + C from the timer time A, and after the time A-B-C has passed, start energizing the heating element 4, and after the timer time A has passed, set it. An electric water heater characterized in that the control means 7 controls the notifying means 24 to notify the user when the temperature reaches the specified temperature.
