Abstract

본 발명은 유도가열 밥솥용 강자성체 코팅용지 및 그 제조방법에 관한것으로, 알루미늄 내통 외벽면에 Ni 또는 Co등과 같은 강자성체 금속이 상기 유도가열밥솥의 가열코일이 장착되어 있는 부분에만 코팅되는 구조를 가지도록 강자성체코팅 용기를 형성 하므로써 1)유도가열 밥솥용 내부 코팅용기를 저가로 제작할 수 있게되며, 2)이로 인해 상기 내부 코팅용기를 적용한 유도 가열밥솥 또한 그 단가를 줄일 수 있게 되고, 3)유도가열코일과 결합되는 부분만을 강자성체로 코팅하므로써 용기자체의 중량을 줄일 수 있게 되어 사용상의 불편함을 개선할 수 있게 된다.The present invention relates to a ferromagnetic coating paper for an induction heating rice cooker and a method for manufacturing the same, so that a ferromagnetic metal such as Ni or Co is coated only on a portion where the heating coil of the induction heating rice cooker is mounted on an outer wall of an aluminum inner cylinder. By forming a ferromagnetic coating container 1) it is possible to manufacture the inner coating container for induction heating rice cooker at a low cost, 2) thereby induction heating rice cooker applying the inner coating container can also reduce the unit cost, 3) induction heating coil By coating only the portion that is combined with the ferromagnetic material it is possible to reduce the weight of the container itself to improve the inconvenience in use.
