In addition, the fan assembly 24 may be preferably disposed directly above the air outlet 102 to further facilitate rapid air circulation. It can be understood that the heat pipe is usually disposed on the top of the oven body 10, so that in the barbecue mode, the air in the upper space of the heating chamber 104 is heated first, while the air in the lower space is at a lower temperature, and disposing the air outlet 102 at the lower position of the heating chamber 104 and the fan assembly 24 above the air outlet 102 can facilitate the air with lower temperature in the heating chamber 104 to be sucked out, so that the temperature in the heating chamber 104 is raised quickly, and in addition, after the heat pipe is started for a period of time, the air circulation can be accelerated by the fan assembly 24, so that the temperature in the heating chamber 104 is higher, and finally the temperature in the heating chamber 104 reaches a higher level. In addition, disposing the air outlet 102 at a lower position of the heating chamber 104 and disposing the fan assembly 24 above the air outlet 102 further facilitates the water vapor discharged from the air outlet 102 to be discharged to the air outlet 140. Preferably, the faces of fan 240 may face toward the intersection area between first and

second passageways

16 and 18. Further, it will be appreciated that the fan 240 may be rotated by the motor 242.

In addition, as shown in fig. 7 and 8 in combination, the air outlet 140 may be formed on the top wall of the air guiding cover 14, and more particularly, the air outlet 140 may be formed on the top wall of the cover sidewall 142, so that the gas, such as water vapor, discharged from the air outlet 102 is easily guided to the outside of the heating cooker when the heating cooker is in the microwave mode.
