secondly, the length of the partition 20 is equal to the length of the air guide groove 11, that is, the front end of the partition 20 extends to the air guide inlet 12, and the rear end of the partition 20 extends in a direction away from the air guide inlet 12.

As shown in fig. 1, in the present embodiment, the front end of the partition portion 20 extends to the front end of the air guide main body 10. The partition part 20 completely partitions the whole air guide groove 11 into at least two air guide channels 21, hot air is divided into a plurality of strands to enter the corresponding air guide channels 21 respectively after contacting the air guide piece, and the hot air enters the cooking cavity under the guidance of each air guide channel 21, so that the air direction and the flow rate of the hot air are easy to control, and the uniformity of air guide is further facilitated to be improved.

As shown in fig. 1 and 4, an arc-shaped air guide surface 24 is provided in the air guide passage 21. After the hot air contacts the arc-shaped air guide surface 24, the hot air can circulate along the arc-shaped air guide surface 24 to change the wind direction, the surface change of the arc-shaped air guide surface 24 is smoother, the hot air can be conveniently reversed, and the wind speed loss of the hot air is smaller. The arc air guide surface 24 may be located on a side wall of the air guide channel 21, and the arc air guide surface 24 may also be located on an end wall of the air guide channel 21. In the present embodiment, after the hot air passes through the arc-shaped air guiding surface 24, the hot air can flow downward along the arc-shaped air guiding surface 24, that is, the wind direction of the hot air is changed from the horizontal direction to the downward direction.
