[0002] At present, the electromagnetic heating equipment on the market has the problem of being unable to heat non-magnetic utensils. When using ceramic pots, casseroles, etc. to heat, electromagnetic cooker products are useless, and the scope of use is severely limited. In order to use such pots, other stoves with open flames or direct heating have to be equipped, resulting in redundant and repeated cooking equipment. In addition, among electric stoves, the heating efficiency of induction cookers should be the highest, which is very economical and practical in daily use, but in order to adapt to all pots, it is necessary to replace the direct heating stove, which makes it difficult for users to make a choice.

[0003] The Chinese invention patent with publication number CN106545900B discloses an induction cooker, which includes: a bottom shell and a panel covering the bottom shell, the panel includes a fire viewing area, a light emitter is arranged in the bottom shell, and the light emitted by the light emitter is projected to the fire viewing area, and an operation panel, a liquid crystal display screen and a microcontroller are also arranged in the bottom shell; the microcontroller is respectively connected to the operation panel, the light emitter and the liquid crystal display screen, and the liquid crystal display screen is located above the light emitter. The induction cooker not only displays virtual flames, but also displays the working parameters of the induction cooker to improve the user experience.

[0004] The Chinese invention patent with the publication number CN107438299A discloses an electromagnetic cooker, including: a control circuit, a charge-discharge circuit, a first transistor and an inductor.

The control circuit is used to send a pulse signal of a preset duration to the base of the first transistor when receiving a heating instruction, so that the voltage of the power supply provided by the charge-discharge circuit to the drive circuit within the preset duration after receiving the heating instruction is less than the voltage provided by the second power supply. When the electromagnetic cooker provided by the invention detects the pot, the drive circuit operates at a lower second drive voltage, avoiding the problem of IGBT damage that may be caused by not placing the pot on the electromagnetic cooker when detecting the pot; by setting the inductor for energy storage buffering, the IGBT is further protected.
