It will be appreciated that the air flows from the air inlet 118 into the cooking apparatus 100, flows to the first region 134, the second region 136, and then flows to the third region and the fourth region under the action of the re-guiding portion 146, and then flows out of the cooking apparatus 100 from the air outlet 120.

The deflector 146 includes a first deflector 148 and a second deflector 150.

The second baffle 150 is connected to the first baffle 148, the first baffle 148 extending toward one side of the cooking cavity 114, and the second baffle 150 extending toward the other side of the cooking cavity 114.

The flow guiding portion 146 includes a first flow guiding plate 148 and a second flow guiding plate 150, and the first flow guiding plate 148 and the second flow guiding plate 150 are connected. Wherein, the extending directions of the first baffle 148 and the second baffle 150 are opposite, the first baffle 148 extends toward one side of the cooking cavity 114, and the second baffle 150 extends toward the other side of the cooking cavity 114. The air flow from the second region 136 flows to the third region under the influence of the first baffle 148 and the air flow from the second region 136 flows to the fourth region under the influence of the second baffle 150. That is, the first and second baffles 148, 150 split the flow of the second region 136 such that a portion of the flow flows to the third region and another portion flows to the fourth region.
