けることにより簡単に製作できる。Action With the above configuration, the central part of the bottom of the pan generates heat by the induction coil on the lower surface of the central bottom, so that the hot water in the pan causes convection along the pan. Also, since the induction coil on the bottom surface of the outer peripheral bottom is arranged at the corner of the pot, it can be made into a substantially flat shape, like the coil on the bottom surface of the central bottom.
It can be easily manufactured by winding it around a molding jig having a constant interval corresponding to the coil diameter.
また、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。In addition, since the ferrite has a simple flat shape, molding can be easily performed.

カバー７に傾斜して取付けている。The outer peripheral induction coil 5 and the central induction coil 6 are divided into two parts at the bottom of the protective frame 3, but they are composed of one coil and are connected. The outer circumference induction coil 5 is arranged along the bottom surface of the pot 2. Further, the ferrite 8 having a simple shape is attached to the protective frame cover 7 while being inclined.

係なく効率的でむだなく調理することができる。As described above, according to the present embodiment, the bottom corner portion of the bottomed cylindrical protective frame that constitutes the pan storage portion has an R shape.
Since the induction coil bisected by the bottom of the protective frame is placed on the lower side of the shape part and the center of the bottom surface, and by placing a simple shaped ferrite on the bottom surface of the induction coil, the bottom surface of the pan heats up, so the pan As convection occurs along with the conventional convection in the case where an induction coil is placed on the lower side surface, it is possible to generate the same convection in the pan and to heat from the bottom of the pan and its surrounding lower part. You can cook efficiently and effortlessly regardless of the amount of food to be stored.
