Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic cooking appliances, in particular to an electromagnetic cooker with an independent double heating core system. Background Art

[0002] The principle of the induction cooker is the electromagnetic induction phenomenon, that is, the alternating current is used to pass through the coil to generate an alternating magnetic field with a constantly changing direction. Eddy current will appear inside the conductor in the alternating magnetic field, and the Joule heating effect of the eddy current will heat up the conductor, thereby achieving heating. The induction cooker generally includes an excitation coil assembly, a heating core system, and a bearing shell. In order to meet the synchronous cooking operation of multiple cooking pots, multi-head induction cooker products have been launched on the market. It usually arranges multiple excitation coil assemblies and heating core systems on the bottom shell. However, the setting of the burner spacing for different multi-burner models results in the need for the electric heating furnace platform to match and set up multiple base models, which is more troublesome for production preparation, production and storage, and the cost is also high. In addition, if the spacing between the burners is short, on the one hand, it is not convenient to arrange the excitation coil, and on the other hand, it is not convenient to arrange the heating core system, and it is not convenient to dissipate heat effectively, and the heat dissipation performance is poor. Therefore, it is sought to design an induction cooker structure that is convenient for coping with the spacing arrangement of multiple burners and convenient for the heat dissipation of the core.
