How is the electromagnetic oven heated?
Induction cooker is the principle of using electromagnetic induction to convert electric energy into heat energy. The rectifier circuit converts 50/60Hz AC voltage into a DC voltage (AC-DC-AC, AC - DC - AC), and then through the control circuit converts the DC voltage into high frequency voltage 20~35KHz, current flowing in the coil speed change generates high speed changing magnetic field, when the magnetic field in the magnetic field generated by countless small eddy metal at the bottom of the vessel the metal body, the vessel itself to high-speed heat, then the heater dish that achieve heating results.
The induction cooker is divided into two categories: low frequency and high frequency according to the current and frequency in the induction coil. Compared with the high-frequency electromagnetic range, the induction cooker has high heating efficiency and saves electricity.
The induction cooker is heated by the electromagnetic induction principle.Furnace surface electromagnetic oven is heat-resistant ceramic plate, an alternating current through the coil produces a magnetic field below the ceramic plate, eddy current magnetic field lines passing through the bottom of wok, stainless steel pot, and the pot bottom heated rapidly to achieve the purpose of heating.
