Referring to fig. 1 and 2, in some embodiments, the width of the air duct 21 gradually decreases along the flow direction of the air duct 21. Specifically, the air duct 21 is formed above the cooking chamber 11. It can be understood that the width of the air duct 21 at the first air outlet 211 is smaller than the width of the air duct 21 at the air supply device 20, the width of the air duct 21 at the second air outlet 212 is smaller than the width of the air duct 21 at the air supply device 20, and the air flows at a constant speed in the air supply device 20, and the flow speed of the air flowing out from the first air outlet 211 and the second air outlet 212 will be relatively large due to the gradually reduced width of the air duct 21 in the flow direction, so that the air curtain 213 can be better formed. In an embodiment, the width of the first air outlet 211 is smaller than or equal to the width of the air duct 21 corresponding to the first air outlet 211, so that the air flow rate flowing out from the first air outlet 211 is relatively large, and the formed air curtain 213 is more firm and stable.

Referring to fig. 1 and 2, in some embodiments, the cooking cavity 11 is formed by the cavity wall 112, the first air outlet 211 is located on the cavity wall 112 near the opening 111 of the cooking cavity 11, and the first air outlet 211 is vertically oriented to the cooking cavity 11. Specifically, the first air outlet 211 is close to the opening 111 of the cooking cavity 11, and since the cooking cavity 11 is formed by the cavity wall 112, the first air outlet 211 is formed on the cavity wall 112 of the cooking cavity 11, so that the air flowing out from the first air outlet 211 can enter the cooking cavity 11, and the high-temperature air in the cooking cavity 11 can be prevented from flowing out of the cooking cavity 11.

Further, the opening 111 of the first air outlet 211 faces the cooking cavity 11 vertically, and the airflow flowing out from the first air outlet 211 is also in the vertical direction, so that the formed air curtain 213 is also in the vertical direction, and because the first air outlet 211 is formed on the cavity wall 112 of the cooking cavity 11, when the door 50 is in an open state, the airflow flowing out from the first air outlet 211 cannot impact on the door 50, so that the user can open the door 50 at any amplitude, and the situation that the user can only open the door 50 by a small amplitude first and then completely open the door 50 after the temperature in the cooking cavity 11 drops can be prevented.
