The principle behind the rice cooker is not complicated, we can understand it as long as we know a little physics.
When the rice is cooked, the water in the rice cooker will evaporate and change from liquid to gas. also when an object changes from liquid to gas, it must absorb a certain amount of energy, which is called "latent heat". at this time, the temperature will remain at the boiling point until the water evaporates, the temperature in the rice cooker will rise again.
There are thermometers and electronic parts in the rice cooker, when it finds that the temperature rises again, it will automatically stop cooking.
Structure of ordinary rice cooker: ordinary rice cooker is mainly composed of heating plate, temperature limiter, insulation switch, lever switch, current limiting resistance, indicator light, socket, etc.
