[0078] In some embodiments, the smoke exhaust fan 6 may be a turbo fan, which can improve the heat dissipation efficiency of the smoke exhaust duct 5, and is conducive to the rapid exhaust of oil smoke and heat dissipation and cooling of the cooking cavity 20.

[0079] It should be noted that, in other embodiments, the smoke exhaust fan 6 may also be other types of fans.

[0080] See also Figures 2 to 8 As shown, in some embodiments, the smoke exhaust duct 5 may include a smoke removal pipe 51. A smoke removal module (not shown in the figure) may be provided inside the smoke removal pipe 51. The smoke removal pipe 51 may filter and purify the oil smoke entering the smoke exhaust duct 5 through the smoke removal module.

One end of the first connecting pipe 511 may be connected to an end of the smoke removal duct 51 away from the smoke exhaust fan 6, so that the first connecting pipe 511 can be connected to the inside of the smoke removal duct 51. The other end of the first connecting pipe 511 may be connected to the air guide cover 32, so that the first connecting pipe 511 can be connected to the heat dissipation duct 3. Therefore, the smoke exhaust duct 5 can be connected to the heat dissipation duct 3 through the first connecting pipe 511, and the oil smoke extracted by the smoke exhaust fan 6 is transported into the heat dissipation duct 3 through the smoke removal duct 51.

[0083] In some embodiments, the smoke exhaust duct 5 may include a second connecting pipe 512. The second connecting pipe 512 may be disposed between the smoke removal duct 51 and the air outlet end of the smoke exhaust fan 6.

At this time, the exhaust passage 530 inside the exterior is not connected to the interior of the inner cylinder 54. The oil smoke in the cooking cavity 20 cannot be discharged to the outside of the box body 1 through the exhaust port 22 and the exhaust passage 530 inside the outer cylinder 53.

[0099] It should be noted that, by virtue of the baffle 541 being rotatably attached to one side of the partition 531, when the second vent 542 is not connected to the first vent 532, the partition 531 and the baffle 541 can form a sealed fit, which can improve the sealing isolation performance between the inside of the inner tube 54 and the outside, thereby effectively improving the reliability of the on-off control of the smoke exhaust duct 5, and can improve the sealing performance of the on-off control of the smoke exhaust duct 5 without any sealing components.
