Who invented the induction cooker?
In 1957, the Germans invented it, specifically who did not know!Most of the "magnetic" produced by the electromagnetic furnace is distributed at the bottom of the pot, forming a closed magnetic field. When the pot on the cooker "work", the highest intensity magnetic field generated by electromagnetic oven at the edge of the induction cooker is 160 without Gauss, the magnetic signals generated when using a mobile phone close to 1600 without Gauss, is 10 times that of the electromagnetic oven surface edge of the magnetic field that influence the electromagnetic oven the magnetic field of the human body is far better than the mobile phone. When the pot with a vertical 3-5cm left panel cooker, the pot will not be beyond the scope of closed magnetic field and the electromagnetic oven heat regeneration, stop working automatically; the horizontal magnetic field outside the scope of the closed magnetic field is very weak, accounting for about 0.1% of the magnetic field energy to zero, or even close to the earth's magnetic field. When the pot is less than the minimum diameter of 8cm, the electromagnetic oven can not work. Therefore, there is no need to worry about the influence of the electromagnetic field on the human body
The heating principle of the electromagnetic oven determines the high efficiency, safety, non pollution, energy saving and convenient use of the product. It is also these characteristics that contribute to the popularization of the electromagnetic oven products in foreign countries
The electromagnetic oven is also called the electromagnetic stove. The first household induction cooker was born in Germany in 1957. In 1972, the United States began producing electromagnetic ovens. In the early 1980s, electromagnetic ovens began to sell well in Europe, America and japan. The principle of induction cooker is magnetic induction eddy heating. The current through the coil produces a magnetic field, when the magnetic field lines within the iron pot through the bottom, cutting lines, resulting in countless small eddy, the iron molecules rotate at high speed and collision friction heat and direct heating of iron pot itself in the pot of food.
