に製作できる。Effect: According to the first means, the tapered surface of the pot bottom generates heat by the induction coil on the lower surface of the outer bottom, so that hot water in the pot causes convection along the pot. In addition, since the induction coil on the lower surface of the outer bottom is arranged from the tapered surface of the pot to the corner, it is the same as the coil on the lower surface of the center bottom. It can be easily manufactured by winding it around a forming jig having a certain interval.
また、第２の手段によれば、フェライトの形状を単純な
フラット形状としているため、成型が簡単にできる。Moreover, according to the second means, since the shape of the ferrite is a simple flat shape, it can be easily molded.

状に形成する。In FIG. 1 showing an embodiment of the present invention, parts that are the same as those in the conventional example are given the same numbers and their explanations will be omitted. The pot 2 is made of the same clad steel plate as the conventional example, and the bottom surface is formed into a tapered shape in the outer circumferential direction of the bottom surface.
また保護枠３の底部外側面３ｂの下側には外周誘導コイ

調理することができる。As described above, according to this embodiment, the induction coil, which is separated by the bottom of the protection frame, is arranged on the bottom outer circumferential surface and the bottom surface of the cylindrical protection frame constituting the storage part of the pot, and By placing a simple-shaped ferrite in the pot, the tapered bottom of the pot generates heat, which generates convection along the pot, generating the same convection inside the pot as when an induction coil is placed on the bottom side of the pot. Moreover, since heating can be performed from the bottom of the pot and the lower part around it, efficient and wasteless cooking is possible regardless of the amount of food stored in the pot.
