In this embodiment, the to-be-heated member 200 is disposed on the heating device 100, and the magnetic fields generated by the plurality of first wire segments 211 are used for coupling with the bottom of the to-be-heated member 200 (such as a pot) disposed on the first side of the stand 20, and are also used for coupling with the side wall 201 of the to-be-heated member, so as to heat the side wall 201 of the to-be-heated member. Under the current packaging shell, under the limited prerequisite of heating surface, because of electromagnetic heating wire group 21 has bigger heating radiation scope, the magnetic field that electromagnetic heating wire group 21 produced is bigger with the effective coupling area of treating heating piece 200, not only can treat the bottom heating of heating piece 200, can also treat the side wall portion 201 heating of heating piece 200, realizes three-dimensional heating for treat heating piece 200 heating effect is better even, and can promote the efficiency of heating, reduce user's use cost.
The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the description of the present utility model and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the utility model.
