The utility model belongs to the technical field of kitchen utensils and appliances, especially, relate to a core and adopt its induction cooker. The core includes electric appliance cavity and heat dissipation chamber, electric appliance cavity sets up with heat dissipation chamber laminating and mutual independence, electric appliance cavity is sealed cavity, be provided with the circuit modulein the electric appliance cavity, the circulation of heat dissipation intracavity has the heat eliminating medium, heat transfer that the circuit module gived off is to dispelling the heat intracavityand give off to the core outsidely through the heat eliminating medium. Simultaneously, the induction cooker who adopts above -mentioned core is still provided. The utility model provides a core through with the circuit module setting at sealed chamber, can prevent the corruption to the circuit module of oil smoke, water smoke to and insects are like the destruction to the circuit such as cockroach. Simultaneously, through the heat dissipation chamber the setting to reach dispel the heat chamber and electric appliance cavity laminating setting, can realize heat transfer between the two, and then the realization prevents to the heat dissipation of circuit module that electric appliance cavity from accumulateing the phenomenon that leads to the circuit module to become invalid because of the heat interior the appearance.
