The wind wheel 533 is sleeved on the fan shaft 531, and the wind wheel 533 is rotatably arranged in the fan cover 532 through the fan shaft 531. Therefore, when the output shaft of the driving motor 6 is axially connected with the fan shaft 531, the driving motor 6 can drive the fan shaft 531 and the wind wheel 533 to rotate in the fan cover 532, and the wind generated by the wind wheel 533 can make the steam in the cooking cavity 50 enter the fan cover 532 through the air inlet 5322, and blow to the upper and lower sides of the steaming screen plate 54 through the air outlet 5321.

[0098] In some embodiments, the end wall of the fan cover 532 facing the steaming net plate 54 is densely covered with a plurality of air outlet holes 5321. The steaming net plate 54 is arranged in the middle area of ​​the plurality of air outlet holes 5321, so that the plurality of air outlet holes 5321 are arranged on the upper and lower sides of the steaming net plate 54, that is, some of the air outlet holes 5321 are located on the upper side of the steaming net plate 54, and some of the air outlet holes 5321 are located on the lower side of the steaming net plate 54. Therefore, when the wind generated by the wind wheel 533 blows the steam toward the steaming net plate 54 through the air outlet holes 5321, it can be blown toward the upper and lower spaces of the steaming net plate 54 at the same time, and the steam in the upper and lower spaces of the steaming net plate 54 can flow upward and downward through the steam holes 541.

[0099] See also Figures 16 to 19 As shown, in some embodiments, the fan shaft 531 is provided with a step surface 5313, and the step surface 5313 is annular.

[0102] In some embodiments, the end of the fan shaft 531 close to the driving motor 6 is rotatably disposed on the end wall of the fan cover 532 facing away from the steam screen plate 54, so that the fan shaft 531 and the wind wheel 533 can rotate stably in the fan cover 532.

[0103] See also Figures 13 to 15 As shown, in some embodiments, the peripheral side wall of the cooking cavity 50 is provided with a first limiting rib 513, and the end wall of the cooking cavity 50 close to the driving motor 6 is provided with a second limiting rib 514. When the fan 53 is installed in the cooking cavity 50, the fan cover 532 is clamped between the first limiting rib 513 and the second limiting rib 514, so that the fan 53 can be fixed in the cooking cavity 50. At the same time, the second limiting rib 514 allows the fan cover 532 to be spaced apart from the end wall of the cooking cavity 50, so that the air inlet hole 5322 can connect to the cooking cavity 50 outside the fan cover 532.

[0104] In some embodiments, the first limiting rib 513 and the second limiting rib 514 are both provided on the bin base 51, so that the fan 53 can be fixed on the bin base 51. It should be noted that in other embodiments, the first limiting rib 513 and the second limiting rib 514 are both provided on the bin top cover 52, so that the fan 53 can be fixed on the bin top cover 52.

[0105] In some embodiments, a notch 535 is formed on the outer peripheral wall of the fan cover 532, and the notch 535 forms a ventilation gap (not shown in the figure) between the outer wall of the fan cover 532 and the peripheral side wall of the cooking cavity 50. Therefore, the air blown toward the peripheral side of the steaming screen plate 54 through the steam holes 541 of the steaming screen plate 54 can flow into the cooking cavity 50 on the side of the fan cover 532 away from the steaming screen plate 54 through the ventilation gap under the wind force of the wind wheel 533, and then enter the fan cover 532 through the air inlet hole 5322, so that when the fan 53 rotates, hot air circulation can be formed in the cooking cavity 50.
