[0002] An electric hot pot is a modern cooking utensil that adopts a double-bottom welding process. The compound ground traction welding process used in the electric hot pot has high thermal efficiency, long service life, and complete functions, and can perform various processing such as frying, frying, steaming, boiling, rinsing, stewing, simmering, and braising.

[0003] The electric heating device of an electric hot pot disclosed in the publication number CN201138873Y utilizes the heating characteristics of a PTC plate and is applied to the heat source of existing general electric hot pots. It has a wide range of applications, a simple structure, and a long service life. It has the advantages of fast heating, good constant temperature characteristics, and strong power automatic compensation ability. However, during the use of this device, since the PTC plate actually requires a relatively large number of individuals to be spliced to form a heating plate in the shape of a complete pot bottom, its overall surface area becomes larger, resulting in a small contact area with the actual contact heat conducting plate, thereby leading to low heat transfer efficiency, slow heating, energy consumption, and time-consuming and complex maintenance operations.
