When the cooking apparatus 10 is in use, the first fan assembly 200 can drive airflow to flow, and since the first air duct 120 and the cooling air duct 310 are communicated through the first air inlet 116, cool air outside the cooking apparatus 10 can enter the cooling air duct 310 from the air inlet 311, enter the first air duct 120 from the first air inlet 116, and be discharged from the first air outlet 113. And the magnetron 700 is arranged at the air outlet, so that cold air entering from the air inlet 311 on the door body 300 can cool the magnetron 700, the temperature of the magnetron 700 is reduced, the magnetron 700 is not affected by high temperature, and the service life of the magnetron 700 is further ensured. The air inlet 311 is arranged on the door body 300, and the air flow is sucked through the cooling air duct 310 of the door body 300, so that the air flow can be prevented from being influenced by the heating high temperature of the box body 100, the air flow is ensured to be stabilized at a lower temperature, and the magnetron 700 can be effectively cooled.
