acquiring a cooking mode;
controlling the oven to enter a single-layer cooking mode or a double-layer cooking mode based on the acquired cooking mode;
the temperature of layers with different heights in the cooking cavity 7 is detected in real time through temperature sensors 9, one of the temperature sensors 9 is a main sensor, and the rest are auxiliary sensors;
controlling the fan assembly 6 to be continuously rotated and adjusting the rotation direction and the rotation speed of the fan assembly 6, and controlling the operation state of the top heating means 51 and the back heating means 52 based on the cooking mode and the temperature detected by the temperature sensor 9 for a preset period of time.
Because when only one deck position had been put when edible material and when the multilayer position had been put edible material in culinary art chamber 7, for reaching better culinary art effect, fan subassembly 6 is inequality with top heating device 51, the required operating condition of back heating device 52, fan subassembly 6 operating condition if by the user self-setting, then it is comparatively complicated, if single-deck and multilayer edible material all cooks with unified step and operating condition with whole, then can't reach better culinary art effect, application scope is narrower.
Due to the above-described problems, the present embodiment designs a single cooking mode and a double cooking mode. The user designates a cooking mode, the oven enters the designated cooking mode, the rotation direction and the rotation speed of the fan assembly 6 are adjusted according to the single-layer cooking mode or the double-layer cooking mode, and the working states of the top heating device 51 and the back heating device 52 are controlled, so that the cooking requirements of the user for different layers of food materials are met.
In the single-tier cooking mode, the user may place food material at any tier within the cooking chamber 7, or the oven may prompt the user to place food material at a specified tier. In the double cooking mode, a user can place more than two layers of food materials in the cooking cavity 7.
In an alternative embodiment, the rotation direction of the fan assembly 6 comprises forward rotation and reverse rotation, the rotation speed of the fan assembly 6 comprises a first rotation speed, a second rotation speed and a third rotation speed, and the first rotation speed is less than the second rotation speed and less than the third rotation speed;
as shown in fig. 9, when the oven is in the single cooking mode:

and if the temperature detected by the main sensor reaches or is higher than the set temperature, controlling the fan assembly 6 to rotate reversely at a second rotating speed.
As there are a warming phase, which mainly aims at bringing the cooking chamber 7 to a suitable cooking temperature, and a warming phase, which mainly aims at keeping the cooking chamber 7 at a certain temperature range, when the food material is baked.
In another alternative embodiment, the rotation direction of the fan assembly 6 comprises forward rotation and reverse rotation, the rotation speed of the fan assembly 6 comprises a first rotation speed, a second rotation speed and a third rotation speed, and the first rotation speed is less than the second rotation speed and less than the third rotation speed;

and if the temperature detected by the main sensor reaches or is higher than the set temperature, controlling the fan assembly 6 to rotate forwards at a second rotating speed.
As there are a warming phase, which mainly aims at bringing the cooking chamber 7 to a suitable cooking temperature, and a warming phase, which mainly aims at keeping the cooking chamber 7 at a certain temperature range, when the food material is baked.
Since the first rotational speed < the second rotational speed < the third rotational speed, it can be understood that the first rotational speed is a low rotational speed, the second rotational speed is a medium rotational speed, and the third rotational speed is a high rotational speed. Because the food in the bottom layer or the middle layer is poor in cooking coloring effect due to uneven heat during multilayer cooking, the forward and reverse rotation of the wind direction is increased, the wind can flow in different directions, and the uniform heat distribution is more easily met as shown in fig. 6 and 7. In the aspect of the rotating speed of the fan assembly 6, the high rotating speed makes the temperature in the furnace uniform more easily, but the high rotating speed can make the surface of the food air-dry quickly, so that the taste of the food is influenced, the low rotating speed can meet the uniform temperature, but the effect is not good at a high speed, but the low speed cannot air-dry the surface of the food quickly.
According to the above, in the single-layer cooking mode of the present embodiment, because only the single-layer food material is used, there is no shielding of the lower layer/middle and lower layer food material and the baking tray 01, the oven is at the temperature rising stage at the beginning, the fan assembly 6 has a low rotation speed, and can satisfy the requirement of uniform heat in the temperature rising stage by single rotation, and meanwhile, the moisture loss is reduced, after entering the heat preservation stage, the fan assembly 6 adopts a middle rotation speed, does not change in rotation, and gives consideration to the temperature and the effect of avoiding the moisture loss. This embodiment is under many cooking modes, because have the multilayer to eat the material, lower floor/well lower floor eat the material and overware 01 shelter from a part rear side hot-blastly, and upper strata is eaten the material and overware 01 shelter from a part top side air inlet, consequently in the intensification stage, fan subassembly 6 need come the balanced culinary art intracavity 7 internal temperature with high rotational speed, after getting into the heat preservation stage, fan subassembly 6 adopts the well rotational speed and change and turn to, change turns to and can make the temperature balance in the culinary art intracavity 7, compromise the temperature and avoid the effect of moisture loss.
In an alternative embodiment, as shown in fig. 10, when the oven is in the single tier cooking mode:
if the temperature detected by the main sensor reaches or is higher than the set temperature, controlling the top heating device 51 and the back heating device 52 to stop heating;
if the temperature detected by the main sensor is lower than the set temperature, controlling both the top heating device 51 and the back heating device 52 to heat;
when the oven is in the multi-layer cooking mode:
if the temperature detected by one of the temperature sensors 9 located close to the top heating device 51 is lower than the set temperature, the top heating device 51 is controlled to heat;
controlling the top heating means 51 to stop heating if the temperature detected by one of the temperature sensors 9 located close to the top heating means 51 reaches or is higher than a set temperature;
if the temperature detected by one of the temperature sensors 9 located close to the back heating device 52 is lower than the set temperature, the back heating device 52 is controlled to heat;
