If it is empty, the electric kettle will boil, so you must add water to it and re-boil it.
When using an ordinary electric kettle, it should not be filled with too little water, otherwise it will burn out quickly. The working principle of the electric kettle is that the water vapor generated when the water boils deforms the bimetallic sheet of the steam temperature sensing element, and this deformation pushes the power switch to cut off the power through the lever principle. Its power off is not self-resetting, so the kettle will not automatically reheat after power off.
About 5 minutes after the electric kettle is connected to the power supply, the water vapor deforms the bimetal sheet of the steam temperature sensing element, and the switch contacts are opened to cut off the power supply. If the steam switch fails, the water in the pot will continue to boil until the water is boiled dry, and the temperature of the heating element rises sharply. There are two bimetallic plates located at the bottom of the heating plate. The temperature will rise sharply due to heat conduction, expansion and deformation, and break Turn on the power. Therefore, the safety protection device of the electric kettle is very scientific and reliable. This is the triple safety protection principle of electric kettles.
