最少の距離で配置されるのが一般である。(b) Prior art An electromagnetic cooker consisting of two or more heating coils is
The heating coils are placed in close proximity to each other.
In order to make the overall spacing as small as possible, they are generally arranged at the minimum distance that does not pose a problem for loading and cooking.

熱コイルが充電部のため製造時における距離管理
が難しくなる。 Therefore, when two or more coils are operated simultaneously, the load is heated in the vicinity of both coils by lines of magnetic force having different frequencies. When the different frequencies interfere with each other and the load is heated, the load may generate an abnormal sound such as a beat sound. Conventionally, in so-called multi-burner electromagnetic cookers that have two or more heating coils, mutual interference prevention material is placed around the outer periphery of the heating coils to prevent mutual interference of magnetic lines of force, but this reduces the size of the device. Since the distance between the heating coil and the mutual interference prevention material is 2 to 3 mm, and the heating coil is a live part, it becomes difficult to manage the distance during manufacturing.

The purpose is to facilitate distance management at times.

Mutual interference prevention materials 4, 4 made of non-magnetic materials such as copper or aluminum are printed on the top plate 1 to face the respective heating coils 2, 2, and the mutual interference prevention materials 4, 4 are printed on the respective heating coils. 2, 2 is arranged so as to cover the outer periphery of the parts. 5, 5 are insulators for insulating the mutual interference prevention materials 4, 4 and the heating coils 2, 2.

無である。 In such an electromagnetic cooker, the presence of the interference prevention materials 4, 4 prevents interference between the magnetic fluxes generated from the plurality of heating coils 2, 2. Moreover, by detecting the state of the electric signal flowing in the interference prevention materials 4, 4 using the crack detection terminals 6, 6, it is detected whether or not there is a crack in the top plate 1. Furthermore, since the insulators 5, 5 are present, the insulation between the interference prevention materials 4, 4 and the heating coils 2, 2 is completely removed, and the electromagnetic cooker is controlled via the crack detection terminals 6, 6. There is no risk of damaging the control circuit by supplying an undesired large current to the circuit.

離管理をする必要もない。According to the present invention, a mutual interference prevention material is provided on the top plate so as to cover the outer periphery of the heating coils arranged close to each other on a flat surface.
The distance between the heating coil and the mutual interference prevention material can be controlled during manufacturing simply by aligning the heating coil and the top plate. There is no need to manage the distance between the heating coil and the top plate in addition to the distance management for positioning the heating coil and the top plate.

If the top plate breaks, it is also possible to stop the operation of the heating coil. Furthermore, the presence of the insulator prevents a short circuit between the heating coil and the mutual interference prevention material, and completely eliminates the risk of destroying the control circuit connected via the split detection terminal.
