Therefore, an accurate temperature reference value can be provided for subsequently judging whether the steam generating device is dry-burned or not.
The water absorption preset time period t1 may be set as needed. Preferably, 1min ≦ t1 ≦ 15 min. Thus, the accuracy of the controller 120 in determining the dry-heating of the steam generating device at the water absorption stage of the cooking stage can be further increased.

In this embodiment, in the water absorption stage of the cooking stage, after the steam generator is heated, if the steam generator can normally generate steam (the steam generator does not burn), the steam generated by the steam generator enters the cooking space from the channel outlet of the steam channel, so that the temperature at the channel outlet is affected by the steam generated by the steam generator and the steam generated by the inner pot. The steam generated by the steam generating device may increase the temperature at the outlet of the channel. Therefore, in the water absorption stage of the cooking stage, after the steam generator is heated, if the average value of the temperature collected by the controller 120 in the water absorption preset time period T1 is less than the first preset temperature value T1, it indicates that the steam generator cannot normally generate steam, and at this time, the controller 120 may determine that the steam generator is in a dry-heating state. At this time, the controller 120 may control the electric heating device to stop heating. The controller 120 can also control the prompt module 130 to send out a dry-burning prompt message. The dry burning prompt message comprises prompt sound and display prompt message. Therefore, the user is convenient to be reminded of adding water into the steam generating device.

Thus, the accuracy of the controller 120 in determining the dry-heating of the steam generating device at the water absorption stage of the cooking stage can be increased.
In the water absorption stage of the cooking stage, after the steam generator is heated, if the average value of the temperature at the outlet of the channel acquired by the controller 120 in the water absorption preset time period T1 is greater than or equal to the first preset temperature value T1, it indicates that the steam generator can normally generate steam, and at this time, the controller 120 may determine that water is in the steam generator and the steam generator is not dry-burned.
