Cooking devices (e.g., ovens, steam ovens, etc.) having a grilling function utilize heated air circulation formed in the inner cavity of the inner container to heat the food. Specifically, the back of the inner container is provided with an air heater, the rear side of the inner cavity of the inner container is provided with a hot air baffle plate, the hot air baffle plate is provided with an air inlet and an air outlet which is arranged around the air inlet, the hot air baffle plate and the back plate of the inner container form a hot air chamber, the fan blade of the air heater is positioned in the hot air chamber and is opposite to the air inlet of the hot air baffle plate, and the periphery of the fan blade is provided with a back heating pipe. For example, chinese patent No. ZL202010218559.7 (issued to CN 111345702B) entitled "oven with uniform temperature field", chinese patent No. ZL202011064662.7 (issued to CN112244660B entitled "oven with hot air structure for cooking apparatus", and the like.

When the cooking device works, the air heater rotates, air in the inner container enters the hot air chamber through the air inlet under the suction action of the fan blades, and hot air in the hot air chamber flows back into the inner container through the air outlet under the centrifugal force action of the fan blades, so that hot air circulation is formed in the inner cavity of the inner container. In the cooking state, the baking tray with the food is horizontally placed on the cooking layer of the inner container (generally, four layers of cooking layers are used, in the single-layer cooking state, the second layer of cooking effect is optimal, in the double-layer cooking state, the second layer of cooking effect and the fourth layer of cooking effect are optimal), and the air flow driven by the hot air circulation acts on the food of the baking tray to heat the food by hot air. However, the existing hot air circulation mode causes uneven distribution of heat in the inner cavity of the inner container, so that food cannot be heated uniformly, and the cooking effect on the food is affected.
