Why doesn't the electric kettle open automatically when the lid is opened?
Because you open the lid, steam directly ran, you cover the lid, the steam will have a hole from the lid, directly into the heat up and shrink the metal sheet, the metal will rise when heated, upturned to the top of the switch, the power will be switched off. If you do not automatically power off, take apart the metal pieces, and slightly break up the point with your hands on it. There is no electronic induction, much of it physics.
Of course has been burning, when the lid is closed without hot air automatic processing device warm, directly from the Hukou run, the sensor does not work.
Principle of automatic power-off of electric kettle:Automatic power-off function is located inside the cup handle (upper, windpipe or the bottom of the cup, this time need a longer the temperature controller) double sheet metal in the form of implementation, and no relay, the thermistor inside, it is a feeling of steam temperature, so the indirect comparison, generally is the breaking point of water after boiling steam temperature to achieve temperature controller. So if you open the lid and boil the water, it won't automatically break.
