A single-coil induction cooker that can use thermal radiation energy and electromagnetic induction energy at the same time

Abstract

The invention provides a single-coil induction cooker capable of simultaneously using thermal radiation energy and electromagnetic induction energy, comprising an induction cooker host, the induction cooker host is connected to a dual-mode coil of thermal energy and electromagnetic induction, and the three-phase or single-phase power frequency power supply is connected to a main board. A radiator is installed on the main board, a switch is installed on the main board, and a main circuit and a control circuit are installed on the main board. The invention has a wide range of applications, the coil is resistant to high temperature and corrosion, and the periphery is coated with a thermal effect amplification rare earth coating layer, which can enhance the heating performance. It has dual heating modes of thermal radiation energy and magnetic energy, and can satisfy most of the requirements. The cooking needs of Chinese families are especially suitable for the material of purple sand, which saves space for the majority of Chinese families and improves thermal efficiency.

Description

technical field [0001] The invention relates to the technical field of stoves, in particular to a single-coil induction cooker that can simultaneously use thermal radiation energy and electromagnetic induction energy. Background technique [0002] Induction cooker is also known as induction cooker. In 1957, the first household induction cooker was born in Germany. 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 to pass through the coil to generate an alternating magnetic field with a constantly changing direction, and an eddy current will appear inside the conductor in the alternating magnetic field (the reason can be referred to Faraday's law of electromagnetic induction). It is caused by the vortex electric field pushing the carrier in...

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 additional heating stoves with other heating methods, such as gas stoves or electric stoves. In today’s urban environment, how to reduce the waste of space is getting more and more attention. Therefore, it is necessary to realize multiple heating on one stove. This problem needs to be solved urgently
