How does the magnetic temperature switch work in the rice cooker
RICE COOKER
A rice cooker is an electrical machine which is use purposely for cooking rice.A simple rice cooker monitors the boiling point of water and take an action based on a set point
HOW IT WORKS
A simple rice cooker has a thermal fuse,a heating elements,two temperature sensors,and two light indicators for cook and warm)
MAGNETIC TEMPERATURE SWITCH
Magnetic temperature switch is use in the cook stage of the rice cooker
The user press the switch to the cook state and the magnet hold it in that state until the temperature reaches or exceed the set boiling point where the magnet then demagnetize at that temperature and open the circuit thus returning the switch state back to warm
Magnetic temperature switch is use in the warm stage of the rice cooker
In the warm state,the thermistor (positive temperature coefficient meaning it's resistance increases with temperature ) monitors the temperature of the heater and if it is high, its resistance increases thereby decreasing the amount of current flowing through the heater hence the heat reduces and vice versa
