Specifically, the number of auxiliary heating elements 40 may be set according to the size of the area of the heating region of the bakeware 20. As an embodiment, when the area of the heating area of the bakeware 20 is small, an auxiliary heating element 40 may be provided, and the distance between the auxiliary heating element 40 and the main heating element 30 may be determined by the size of the area of the heating area of the bakeware 20. The temperature controller can be closely arranged at the position of the heating element corresponding to the temperature controller so as to accurately detect the temperature reached by the heating area of the baking tray 20 corresponding to the heating element corresponding to the temperature controller.

The auxiliary heating element 40 corresponding to the auxiliary temperature controller 60 may be controlled to be turned off when the second temperature detected by the auxiliary temperature controller 60 is less than the corresponding lower temperature threshold. In other embodiments, the auxiliary temperature controller 60 may be controlled to be turned off according to the temperature difference between the first temperature and the second temperature.
Specifically, when the obtained second temperature is greater than the upper limit temperature threshold corresponding to the auxiliary heating element 40 and the auxiliary heating element 40 is in a heating state, determining whether the obtained temperature difference between the first temperature and the second temperature is less than a second preset temperature difference, wherein the second preset temperature difference is less than the first preset temperature difference; if yes, the auxiliary temperature controller 60 corresponding to the auxiliary heating element 40 is controlled to be disconnected.
In this embodiment, the main heating element 30 and the auxiliary heating element 40 are operated simultaneously, the temperature difference therebetween is gradually reduced, and when the temperature is reduced to be less than the second preset temperature difference, the auxiliary heating element 40 may be controlled to stop heating.
Optionally, the first preset temperature difference is set to 18-22 degrees, and the second preset temperature difference is set to 1-15 degrees.
