The inner container of electric casserole is generally made of ceramic material. When this material is directly heated by the high temperature of open flame, it is easy to produce thermal shock cracks, which will lead to the rupture or explosion of the liner. This will not only damage the performance of the electric casserole, but also cause fire or other safety accidents. Therefore, when using the electric casserole, users must abide by the safety guidelines in the instruction manual and avoid putting the inner container directly on an open flame. If the inner container of electric casserole is damaged, it should be replaced or repaired in time. Do not use open fire to repair, to ensure safe use.
