What is the structure of an electric kettle?
How does an electric kettle boil water?Answer: it converts electrical energy into heat energy (Tie Bang) that transfers heat energy to water and makes it boil only(seems to be junior high school level) a little simple
The electric kettle is energized after about 5 minutes, the water temperature gradually increased to 100 degrees, the water begins to boil, the bimetal steam steam impingement on the switch, due to thermal expansion and contraction function, double sheet metal expansion deformation, the top opening of the switch contacts disconnect the power supply. If the steam switch failure, the water in the kettle will always burn down, until the water is boiled, the sharp rise in the temperature of the heating element, heating plate at the bottom of the two double metal sheet, because of the effect of heat conduction temperature rise sharply, swelling deformation, disconnect the power supply. Therefore, the electric kettle safety protection device is designed, very scientific and reliable. This is the electric kettle three heavy safety protection principle.
The structure and working principle of electric kettle power heating electric kettle, the water temperature gradually increased to 100 degrees, the water begins to boil, the bimetal steam steam impingement on the switch, due to thermal expansion and contraction function, double sheet metal expansion deformation, open top switch contacts disconnect the power supply. If the steam switch failure, the water in the pot will always burn down, until the water is boiled, the sharp rise in the temperature of the heating element, heating plate at the bottom of the two double metal sheet, because of the effect of heat conduction temperature rise sharply, swelling deformation, disconnect the power supply. So the safety protection device of electric heating kettle is designed very scientific and reliable. This is electric kettle three heavy security principle.
