电饭煲

Induction rice cookers were specifically developed to heat up an inner pot efficiently to cook rice perfectly. Induction-heating (IH) models are popular not only in Japan but also elsewhere in Asian. Compared to non-IH electric rice cookers, IH models provide higher thermal efficiency and lower power consumption. Induction heating makes it possible to cook perfect fluffy rice quickly at elevated temperatures. IGBTs are used for induction heating, and triac-output photocouplers to drive pot heaters. A microcontroller provides overall control, and transistors drive a cooling fan. High-end models have a side heater in addition to a bottom heater to provide high-power heating. Some models also have a top heating coil to prevent water drops from forming on the lid during warming mode; IGBTs are employed to switch this heating coil on and off.
