Queenwins is a professional manufacturing and sales of hotels, restaurants, bars, kitchens and other catering supplies and equipment. The Induction cooker was invented in Germany in 1957. In 1972, the United States began to produce induction cookers. In the early 1980s, it began to sell well in Europe, America and Japan. The principle of the induction cooker is electromagnetic induction, that is, the alternating magnetic field with changing direction is generated by the alternating current through the coil, and the vortex current will appear inside the conductor in the alternating magnetic field, which is caused by the vortex electric field driving the carrier movement in the conductor; The joule heat effect of vortex current makes the conductor warm up, thus realizing heating.
