Preferably, as... Figure 3 , Figure 4 , Figure 7 As shown, the electromagnetic coil 23 is stacked in at least two layers between the base 21 and the magnetic strip frame 22, and the electromagnetic coil 23 in each layer is wound multiple times, with adjacent turns of the electromagnetic coil 23 in contact with each other. The electromagnetic coil 23 is wound in a multi-layer dense winding manner, which makes the magnetic field lines generated by the coil being energized more dense and the magnetic field strength stronger, thereby greatly improving the electromagnetic heating efficiency.

[0072] Among them, such as Figure 2 As shown, the electromagnetic coil 23 is wound in a circular shape. Of course, the electromagnetic coil 23 can also be wound in an elliptical, square, or triangular shape, etc., which is not limited here.

[0073] The utility model discloses still disclose a kind of cooking utensils, including pot body and the inner container placed in the inside of pot body, still including the cooking utensils electromagnetic wire disc of above, electromagnetic wire disc is located below inner container, inner container has bottom wall, side wall and the transition section between bottom wall and side wall, bottom wall of disc body 1 is around with bottom coil 4, coil support 2 is fixed to the side wall of disc body 1, bottom coil 4 corresponds bottom wall, coil support 2 corresponds side wall and / or transition section.

[0074] In cooking process, bottom coil 4 heats bottom wall, and electromagnetic coil 23 on coil support 2 heats inner container side wall and / or transition section, by bottom heating and side heating, realize the multi-directional encircling three-dimensional heating to food, make food heated more evenly, improve heating efficiency, also guarantee each area food taste balance.

[0075] And, according to need, a certain one or more heating zones are separately controlled to heat, to realize the pertinence heating of inner container area. For example, in the heat preservation stage, only electromagnetic coil 23 can be controlled to be powered on, and inner container side is heated, and bottom coil 4 is not powered on, so that heat is concentrated in inner container side, and heat is quickly transferred to upper food, avoid the heating of bottom layer food to cause the heat upward transmission path to be long, and make bottom layer food happen to be burnt.

[0076] The utility model does not state the place in the utility model and can be realized by using or referring to existing technology.

[0077] Each embodiment in the specification adopts progressive mode and describes, and same similar part in each embodiment can be referred to each other, and each embodiment emphasizes the place that is different from other embodiments.

[0078] The above only is the embodiment of the utility model, and is not used to limit the utility model. For the person skilled in the art, the utility model can have various changes and changes. Any modification, equivalent replacement, improvement etc. in the spirit and principle of the utility model should be included in the claim range of the utility model.
