Problems solved by technology
However, only one electromagnetic induction coil can only be used to heat the same local area, and it is difficult to control the heating effect of different parts by uniform heating of the heated whole. The control method is relatively inflexible, and the heating effect of different parts is different during the heating process. Affect the overall heating effect
[0004] In other implementations using multiple electromagnetic induction coils, heating control can be performed by configuring multiple electromagnetic induction coils independently placed in different parts, but due to the design limitations of its coil structure and control circuit, its structure is relatively Complicated and takes up a lot of space, which affects its application range

Description
technical field [0001] The present application relates to the field of thermal processing, in particular to an electromagnetic induction heating module and heating equipment. Background technique [0002] The heating scheme based on electromagnetic induction is widely used in various thermal processing fields, and has the characteristics of safety and high heating efficiency. [0003] Nowadays, the heating equipment adopting the electromagnetic induction heating scheme usually heats the heating appliance by placing an electromagnetic induction coil under the appliance to be heated by the principle of electromagnetic induction. However, only one electromagnetic induction coil can only be used to heat the same local area, and it is difficult to control the heating effect of different parts by uniform heating of the heated whole. The control method is relatively inflexible, and the heating effect of different parts is different during the heating process. affect the overall he...
