[0028] like Figure 3-4 As shown, the cooking cavity 11 has a vertical partition 12 and a top wall 13; the airflow generating device 20 is installed at the rear side of the vertical partition 12, wherein the vertical partition 12 is located at the rear of the cooking cavity 11, and can be used as a rear partition of the cooking cavity 11 on the one hand, and can protect the airflow generating device 20 on the other hand. Specifically, the airflow generating device 20 includes a blast wheel 21 and a heating component 22, the blast wheel 21 is vertically arranged, and the heating component 22 is, for example, an electric heating coil, which is installed at the front side of the blast wheel 21 to heat the airflow generated by the blast wheel 21, thereby forming a hot airflow.

[0029] An air guide portion 14 is provided on the top wall 13 of the embodiment, and the air guide portion 14 is recessed upward from the side portion of the top wall 13 adjacent to the vertical partition 12 and extends forward; wherein at least a portion of the hot air flow generated by the air flow generating device 20 flows downward after being guided by the air guide portion 14 and enters the storage container 30 from the top opening of the storage container 30, thereby being able to heat the food in the storage container 30 more evenly.

[0030] Furthermore, the air guide portion 14 has a top air guide plate 141 and a front air guide plate 142, and the top air guide plate 141 and the front air guide plate 142 are preferably integrally formed; wherein an air inlet 143 of the air guide portion 14 is formed between the rear edge of the top air guide plate 141 and the top edge of the vertical partition 12, and the front air guide plate 142 is located below the top air guide plate 141 in the height direction to guide the gas to flow downward, such as Figure 4 As shown by the arrow in the figure.

[0031] Exemplarily, the top air guide plate 141 is a horizontal plate, and the front air guide plate 142 is an arc-shaped plate; in other embodiments, the top air guide plate 141 and the front air guide plate 142 may also be inclined plates or other air guide structures, which will not be elaborated here one by one. Preferably, in the height direction, the distance between the top air guide plate 141 and the top edge of the vertical partition 12 is set to not exceed 1 / 4 of the height of the cooking cavity 11, for example, the distance between the top air guide plate 141 and the top edge of the vertical partition 12 is set to 1 / 5 of the height of the cooking cavity 11; in the front-to-back direction, the distance between the front side edge of the top air guide plate 141 and the vertical partition 12 is set to exceed 1 / 2 of the depth of the cooking cavity 11, for example, the distance between the front side edge of the top air guide plate 141 and the vertical partition 12 is set to 2 / 3 of the depth of the cooking cavity 11. In the embodiment, the main airflow is more evenly guided to the storage container 30 by the air guide portion 14 having a certain height and depth, which is more conducive to the cooking of food in the storage container 30.
