Filter structure and working principle of the kettle electric kettle heating after turning on the power supply, water temperature gradually rises to 100 degrees, the water begins to boil, steam impact switch on bimetallic above, under the action of thermal shrinkage, double metal expansion deformation, press the switch contact to cut off the power supply. If the steam switch failure, will burn until the water of the water in the kettle, the temperature of the heating element will rise sharply, and there are two double metal plate at the bottom of the heating plate, due to the heat transfer temperature rise sharply, expansion deformation, disconnect the power supply. Therefore, the filter of the kettle is very scientific and reliable safety protection device. This is the triple filter kettle safety protection principle.
