[0031] The cooking cavity 2 is located in the area surrounded by the inner pot 1. A heating element 3 is arranged inside the cooking cavity 2. The heating element 3 can be arranged at the upper part and / or the lower part of the cooking cavity 2. Preferably, the heating element 3 is arranged as a heating tube. A camera module 9 is arranged at the middle position of the upper part of the rear wall 4. Preferably, the camera module 9 is arranged at a position adjacent to the top surface 6 of the upper part of the rear wall 4 of the inner pot 1. The camera direction of the camera module 9 is tilted downward to face the food in the cooking cavity 2. The arrangement of the camera module 9 can increase the camera angle and field of view, and the view will not be blocked by the heating element 3 on the top of the cooking cavity 2, thereby improving the accuracy of food recognition.

[0032] At least one light emitting element 10 is further arranged inside the cooking cavity 2 . Preferably, the light emitting element 10 is arranged on the top surface 6 or the side surface 5 and faces the cooking cavity 2 , or is arranged on the rear wall 4 adjacent to the camera module 9 and faces the cooking cavity 2 .
