The heat dissipation air duct is formed by enclosing an air duct bottom plate 62 and an air duct cover plate 61, the air duct bottom plate 62 is detachably connected with the mounting top plate 8, and the air duct cover plate 61 is connected with the air duct bottom plate 62 in a buckling mode. The heat dissipation wind channel extends along the preceding back direction of cooking device, and wind channel bottom plate 62 and wind channel cover plate 61's front end all with front panel 4 butt, and wind channel bottom plate 62's front end and wind channel cover plate 61's front end surround and form the wind channel export, and air outlet 41 has been seted up to the position that front panel 4 corresponds the wind channel export to the wind that the messenger was dispelled the heat wind channel condensation is discharged from air outlet 41.

The heat dissipation fan 63 is disposed at the rear end of the heat dissipation air duct, and the heat dissipation fan 63 seals the rear end of the heat dissipation air duct. The radiator fan 63 may be, but is not limited to, a cross-flow fan. The heat dissipation assembly 6 may be disposed by referring to the prior art, which is not the focus of the present invention, and the present invention is not described herein again.

As shown in fig. 1, since the temperature of the steam is limited, in order to increase the heating speed of the food and enrich the function of the cooking device, a heating assembly 7 is further disposed in the inner container 3, and the heating assembly 7 includes a heating pipe. Preferably, heating pipes are arranged on the left side wall, the right side wall and the top wall of the inner container 3, so that the heating efficiency and the heating temperature are improved, and the baking function of the cooking device is realized.
