What do you mean by the three heavy safety protection of electric kettle?
Electric kettle when you buy what is said, the water power off automatically, anti dry ah these, in fact, the heating kettle on the heating pipe, the heat dispersion to the aluminum plate to transfer heat to the heating plate, those things are all manufacturers said, the water is cut off the pot, a steam pipe, the water boiled water vapor through the tube on the bottom of the thermostat, when the temperature reaches a certain degree automatically broken, anti dry ah is also heating plate temperature will also increase rapidly, it is easy to burn the disc, all electric kettle has the thermostat. What is the protection of several businesses with the publicity
1 water power off protection, 2 double anti dry fire protection; 3 high temperature fuse protection
Connect the power supply electric kettle is heated, the 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 kettle will always burn down, until the water dry, the temperature of the heating element at the bottom of the heating tray rises sharply, there are 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 the electric kettle three heavy security protection principle.
