Electromagnetic high-frequency stoves have similarities with current induction cookers, but there are many differences. To be precise, the electromagnetic high-frequency stove is an upgraded product of the electromagnetic stove. The same is only the principle and structure of heating, but there are many differences, and the functions and performance are completely different. The electromagnetic stove is a product of the modern kitchen revolution, which generates heat directly at the bottom of the pot without the need for open flames or conductive heating, thus greatly improving thermal efficiency. It is an efficient and energy-saving kitchen utensil, completely different from all traditional heated or non heated conductive kitchenware. An induction cooker is an electrical cooking appliance made using the principle of electromagnetic induction heating. It consists of high-frequency induction heating coil (i.e. excitation coil), high-frequency power conversion device, controller, and ferromagnetic material pot bottom cookware. When in use, alternating current is introduced into the heating coil, and an alternating magnetic field is generated around the coil. Most of the magnetic lines of the alternating magnetic field pass through the metal pot body, generating a large amount of eddy currents in the bottom of the pot, thereby generating the heat required for cooking. There is no open flame during the heating process, so it is safe and hygienic
