The induction cooker, also known as the induction cooker, is a product of the modern kitchen revolution. It does not require an open flame or conduction heating but allows heat to be generated directly at the bottom of the pot, so the thermal efficiency has been greatly improved. It is a high-efficiency and energy-saving kitchenware, which is completely different from all traditional heat or non-fire conduction heating kitchenware. Induction cooker is an electric cooking appliance made by the principle of electromagnetic induction heating. It is composed of high-frequency induction heating coils (excitation coils), high-frequency power conversion devices, controllers, and ferromagnetic pot-bottom cooking utensils. When in use, an alternating current is passed into the heating coil, and an alternating magnetic field is generated around the coil. Most of the magnetic field lines of the alternating magnetic field pass through the metal pot body, and a large amount of eddy current is generated in the bottom of the pot, thereby generating heat required for cooking. There is no open flame during the heating process, so it is safe and hygienic.
