Comparison of the working principle between electromagnetic induction and traditional electric heating

picture lets you understand the advantages of OLVYUAN commercial induction cooker

Ordinary electric heating furnace is also called electric furnace. It is a resistance wire (electric furnace wire) that converts electric energy into thermal energy after being energized. There are many conductive metal wires inside. Passed the current. Because of the electrical resistance in the metal, the current is lost and the heat is released. Therefore, the electric furnace wire is all red, the thermal efficiency is low, it is relatively expensive, the heating speed is slow, there is residual temperature after stopping heating, and the life of the electric heater wire is short.

A high-power induction cooker generates an alternating magnetic field through the components of an electronic circuit board. When an iron-containing cookware is placed on the bottom of the cooker, the cooker cuts the alternating magnetic lines of force and generates an alternating current (ie, eddy current) ), The eddy current causes the iron molecules in the pot to move at high speed and irregularly, and the molecules collide and friction with each other to generate thermal energy. (The efficiency is nearly 1 times higher) so that the appliance itself generates heat at high speed for heating and cooking food, thereby achieving the purpose of cooking. It has the advantages of fast heating, high thermal efficiency, no open flame, no soot, no harmful gas, no heat radiation to the surrounding environment, small size, good safety and beautiful appearance, etc., and can complete most of the cooking tasks in the home. Therefore, in some countries where the induction cooker is more popular, people call it "the god of cooking" and "green stove".
