Working principle of electric kettle: After the electric kettle is connected to the power supply for heating, the water temperature gradually rises to 100 degrees, and the water begins to boil, and the steam impacts the bimetal on the steam switch. Due to the effect of thermal expansion and contraction, the bimetal expands and deforms, and the switch contact is pushed away, disconnecting the power supply. If the steam switch fails, the water in the kettle will continue to burn until the water is dry, and the temperature of the heating element will rise sharply. There are two bimetals at the bottom of the heating plate, and the heat conduction temperature will rise sharply and expand and deform, thus disconnecting the power supply.
