Subsequently, from the 1980s to the 1990s, with the development of microelectronics technology and automation control technology, the performance of ceramic electric stew pots was significantly improved, and the functions became more diverse and convenient. After entering the 21st century, ceramic electric stew pots have been widely used around the world, and the product types and functions have been continuously enriched to meet the needs of different consumers. However, when heating the aluminum pot, the heat is often transferred outward along the outer wall during the continuous heating process, resulting in heat waste. Therefore, a ceramic electric stew pot wrapped insulation structure is required.

[0003] The application number retrieved is: CN202122120574.0. A large-capacity ceramic electric stew pot is beneficial to the heat dissipation of the inner pot by arranging multiple heat dissipation teeth on the edge of the pot. The heating element is designed as a stepped structure that matches the depression at the bottom of the pot. Combined with the unglazed bottom, the heating efficiency is higher, the pot body has a larger capacity, and can hold more ingredients.
