Rice cooker was first discovered by Yoshitada Minami. In 1937, the Japanese army began to run the device working principle of the electric-powered rice cookers. Initially, the rice cooker used consisted of wood container leak-proof and metal plate electrically powered. The metal plates had a function to heat wood container which was already filled with rice and water in it. The wood container that was heated by the metal makesthe rice cooked. At that time, the process of turning the rice into the cooked rice took a very long because the wooden container used had not been fitted cover yet. As a result, the heat generated from the boiling water in the container was wasted into free air.
Now, the world has changed and the principle of small rice cooker gets better. You can find so many modern rice cookers that are available in the market. Those small rice cookers have the better functions that can cook rice faster. Thus, you must wonder how exactly this small rice cooker works so it can make the rice cooked faster and delicious.

When the heater temperature reaches a maximum and the rice is cooked, the thermostat trip (automatic magnet) immediately moves the lever so that the switch position changes to supply power to rice warming element through the thermostat.
At warmer position when the temperature thermostat has a maximum, the power flow leading to the warming element will be disconnected automatically, as well as the temperature on the thermostat automatically decreases the flow toward the warming element will be reconnected automatically, this process will take place continually.
