The smoke baffle cavity 122 is in communication with the at least one smoke exhaust port 123, so that the cooking oil in the smoke baffle cavity 122 can be timely exhausted upward through the smoke exhaust port 123. The cooking cavity 121 is in communication with the smoke baffle cavity 122 or the smoke exhaust port 123 through the exhaust port 1522, so that the combustion flue gas in the cooking cavity 121 can be exhausted upward from the exhaust port 1522.
