[0028] An embodiment of the present application provides a cooking device, which can be a steam oven, an oven, or any existing cooking device containing the fan baffle 100 described below. In the present embodiment, the cooking device includes the fan baffle 100 in any of the embodiments described below, and further includes an inner container which is hollow inside, and the fan baffle 100 is installed on the inner container to form a cooking cavity and a hot air cavity arranged separately inside the inner container, the cooking cavity is used for cooking food, and the hot air cavity is used for air circulation with the cooking cavity.

[0029] Referring to Figure 1 , Figure 1 A structure diagram of the fan baffle 100 and the upper mounting plate 200 in an embodiment of the present application is shown. In an embodiment, the cooking device further comprises an upper mounting plate 200 located above the inner container, the upper mounting plate 200 is used for mounting electronic components for the cooking device, and the upper mounting plate 200 physically separates the inner container and the space above the upper mounting plate 200 to avoid the influence of high temperature of the inner container on the electronic components above the upper mounting plate 200.

[0030] In combination Figure 2 as shown, Figure 2 A structure diagram of the fan baffle 100 in an embodiment of the present application is shown. The fan baffle 100 provided in an embodiment of the present application can be applied to the cooking device described above, but is not limited thereto.

[0031] As Figure 1 and Figure 2 shown, the fan baffle 100 comprises a plate body 110 and a baffle 120. The plate body 110 is provided with a plurality of through holes 111 for air circulation between the cooking cavity and the hot air cavity. As Figure 1 and Figure 3 shown, in an embodiment, the through holes 111 comprise a return air port 112 located in the central region of the plate body 110 and an air inlet port 113 located in the outer periphery of the return air port 112. Generally, the fan located in the hot air cavity will form a negative pressure area in the center of the fan due to the rotation of the fan blades, so that the through holes 111 located in the central region of the plate body 110 are used for return air, i.e. air flow from the cooking cavity to the hot air cavity, and the through holes 111 located in the outer periphery of the return air port 112 are used for air inlet, i.e. air flow from the hot air cavity to the cooking cavity.

[0032] The baffle 120 is slidably connected to the plate body 110, and the baffle 120 comprises a covering portion 124 corresponding to each of the through holes 111. The baffle 120 can move between a shielding position as Figure 2 shown and a ventilation position as Figure 3 shown. As Figure 2 shown, when the baffle 120 is in the shielding position, the covering portion 124 shields the corresponding through hole 111, at this time, only the plate body 110 and the shielded through hole 111 can be seen from the opening of the cooking cavity, and the fan blades and oil stains inside the hot air cavity cannot be seen, which not only improves the aesthetics of the cooking device, but also avoids touching the fan blades, thereby improving the safety. As Figure 3 shown, when the baffle 120 is in the ventilation position, the covering portion 124 covers the positions of the plate body 110 other than the through holes 111, so that the baffle 120 has no influence on the air inlet and return of the plate body 110 and does not interfere with the air circulation between the hot air cavity and the cooking cavity when the cooking device is normally working.

[0033] As shown in Figure 1 and Figure 2 , in the present embodiment, the baffle 120 is located on the side of the plate body 110 away from the cooking cavity, so as to avoid poor aesthetics caused by the baffle 120 being visible from the opening of the cooking cavity, so that only the plate body 110 and the covered through holes 111 can be seen from the opening of the cooking cavity, so as to make the aesthetics higher.

[0034] As shown in Figure 2 and Figure 3 , the baffle 120 includes a return air baffle 121, a first air inlet baffle 122 and a second air inlet baffle 123, which can move synchronously or be controlled independently, without limitation.
