Because the temperature in the pot body needs to be monitored when baking and cooking are carried out, the heat insulation protection assembly 90 is arranged to prevent heat from directly radiating to the temperature sensing element 60, and the action frequency of the temperature sensing element 60 is reduced. The temperature sensing element 60 extends downwards from the cover assembly 30, and penetrates through the baking assembly 40 and the inner cover 50 to reach the pot body, and the baking assembly 40 is easy to affect the temperature sensing element 60 when in work.
