Double-layer coil electromagnetic oven capable of synchronously using double modes of heat energy and electromagnetic induction

Abstract

The invention provides a double-layer coil electromagnetic oven capable of synchronously using double modes of heat energy and electromagnetic induction. The double-layer coil electromagnetic oven comprises an electromagnetic oven main machine; the electromagnetic oven main machine is connected with a heat energy and electromagnetic induction double-mode coil; a three-phase or single-phase industrial frequency power supply is connected with a main board; a radiator is mounted on the main board; a switch is mounted on the main board; and a main circuit and a control circuit are mounted on the main board. The double-layer coil electromagnetic oven is wide in application range; coils resist high temperature and corrosion, and are coated with heat effect amplification rare earth coating layersat the outer peripheries to improve the heating performance; double heating modes of heat radiation energy and magnetic energy are owned; meanwhile, the double modes of heat energy and electromagnetic energy can meet the cooking demands of most Chinese families; and the double-layer coil electromagnetic oven is particularly suitable for a purple sand material, saves the space for vast Chinese families, and improves the heat efficiency.

Description

technical field [0001] The invention relates to the technical field of stoves, in particular to a dual-mode double-coil electromagnetic stove that can use thermal energy and electromagnetic induction at the same time. Background technique [0002] Induction cooker, also known as induction cooker, was born in Germany in 1957. In 1972, the United States began to produce induction cookers, and in the early 1980s, induction cookers began to sell well in Europe, America and Japan. [0003] The principle of the induction cooker is the phenomenon of electromagnetic induction, that is, the use of alternating current through the coil to generate an alternating magnetic field whose direction is constantly changing, eddy current will appear inside the conductor in the alternating magnetic field (for reasons can refer to Faraday's law of electromagnetic induction), which It is caused by the eddy electric field pushing the carriers in the conductor (the electrons in the pot are not iron...

Problems solved by technology

[0004] With the development of the society and the progress of the economy, ordinary induction cookers gradually show their disadvantages, including the small range of use and high requirements for pots, especially for casserole-like non-metallic health pots that Chinese families value very much. It is necessary to prepare an additional thermal stove, such as a gas stove or an electric stove. In today's cities where every inch of land is expensive, how to reduce the waste of space is getting more and more attention. A problem needs to be solved
