[0042] S11: During the first heating stage, the first heating mechanism, the second heating mechanism, and the third heating mechanism are activated.

[0043] Optionally, in the first heating stage, based on the first heating temperature T1, the aerodynamic mechanism 130, the first heating mechanism 141, the second heating mechanism 142 and the third heating mechanism 143 are turned on for preheating, and the total power of the aerodynamic mechanism 130, the first heating mechanism 141, the second heating mechanism 142 and the third heating mechanism 143 is 2500-3500W.

[0046] Optionally, in the second heating stage, the second heating temperature T2 of the second heating stage is determined based on the first heating temperature, and the second heating time t2 is determined; wherein, T1-50≤T2≤T1+50℃, 1≤t2≤8min.

[0047] Optionally, in the second heating stage, based on the second heating temperature T2 and the second heating time t2, the aerodynamic mechanism 130 and the second heating mechanism 142 are activated to heat the lower and middle layers. The power of the second heating mechanism 142 is 1400-1900W.

[0048] Optionally, in the second heating stage, the second heating mechanism 142 generates heat at the back of the box 110, and the heat is carried into the interior of the box 110 by the aerodynamic mechanism 130, mainly heating the middle and lower layers, and heating the food evenly through the flow of hot air.

[0049] S13: In the third heating stage, the first heating mechanism and the third heating mechanism are turned on.

[0050] Optionally, in the third heating stage, the third heating temperature T3 of the third heating stage is determined based on the second heating temperature, and the third heating time t3 is determined; wherein, T2≤T3≤T2+40℃, 0.5≤t3≤6min.

[0051] Optionally, in the third heating stage, based on the third heating temperature T3 and the third heating time t3, the aerodynamic mechanism 130, the first heating mechanism 141 and the third heating mechanism 143 are activated to heat the upper layer. The power of the first heating mechanism 141 is 750-1050W and the power of the third heating mechanism 143 is 650-950W.

[0053] Optionally, the working time of the first heating mechanism 141 is 0-5 seconds shorter than that of the third heating mechanism 143. Since the third heating mechanism 143 mainly heats the upper layer by radiating heat to the surface of the food, while the bottom of the food is in direct contact with the food placement mechanism 120, and the first heating mechanism 141 mainly heats the lower layer by conducting heat to the bottom of the food, and the heat transfer coefficient of the tray is higher than that of air, the working time of the first heating mechanism 141 is shorter than that of the third heating mechanism 143, ensuring uniform heating of the upper and lower parts of the food.

[0054] S14: In the fourth heating stage, the corresponding heating mechanism is activated alternately with the second heating stage and the third heating stage.

[0055] Optionally, in the fourth heating stage, the second and third heating stages are operated alternately, with the corresponding heating mechanisms activated for cyclic heating. For example, a first and second operating time can be preset. First, the second heating stage is run, and based on the second heating temperature T2 and the first operating time, the aerodynamic mechanism 130 and the second heating mechanism 142 are activated to heat the lower and middle layers. Then, the third heating stage is run, and based on the third heating temperature T3 and the second operating time, the aerodynamic mechanism 130, the first heating mechanism 141, and the third heating mechanism 143 are activated to heat the upper layer. This alternating operation ensures that the food in each layer is heated evenly, achieving a good cooking effect.

During the cooking process, in which the aerodynamic mechanism and at least some of the heating mechanisms are activated to cook the food, the cooking process includes multiple heating stages, with at least two heating stages corresponding to different activated heating mechanisms. By using the above-described cooking device, with multiple heating mechanisms disposed at multiple positions corresponding to different heights within the housing, and the cooking process involving the activation of the aerodynamic mechanism and heating mechanisms including multiple heating stages, the activation of different heating mechanisms during multiple heating stages ensures uniform heating of each layer, reduces temperature deviations between different layers, achieves good cooking results, and improves the user experience of the product.
