The air fryer is a new household cooker in recent years, and generally comprises a shell at the bottom, an inner pot assembly arranged in the shell, and an upper cover assembly covered at the top of the shell, wherein the upper cover assembly comprises a reflecting cover with a downward opening, a heating element arranged in the reflecting cover and a centrifugal fan, and the inner pot assembly comprises an inner pot and a grill arranged at the bottom of the inner pot. When the oil-free baking pan is used, food is placed on the baking rack of the inner pan and the upper cover assembly is covered, the heating element generates heat at the moment, the centrifugal fan is started to blow out high-speed airflow, the high-speed airflow is changed into downward airflow under the action of the reflecting cover, and the heating element changes the downward airflow into high-temperature hot air, so that the food on the baking rack is baked without oil.

However, the existing steam air-frying still has the following defects: the high-speed air flow blown by the centrifugal fan is guided downwards by the edge of the reflector and is changed into high-temperature air flow by the heating element. That is, the high temperature air flows downwards along the side wall of the inner pot to form primary hot air, the temperature of the primary hot air is reduced after the primary hot air blows over the food materials around the grill, the primary hot air rises upwards again from the middle of the inner pot to form secondary hot air, the secondary hot air bakes the food materials in the middle of the grill, the secondary hot air is sucked upwards by the centrifugal fan, and the secondary hot air flows downwards along the side wall of the inner pot again under the driving action of the centrifugal fan and the secondary heating of the heating element, so that the food on the grill is heated and baked in a continuous cycle. It will be appreciated that the temperature of the heating element varies from place to place in the circumferential direction, resulting in a certain variation of the temperature of the downwardly directed hot air in the circumferential direction of the inner pan, which variation of temperature over the cooking toast of the food material results in a non-uniform maturity of the food material on the grill. In order to ensure the maturity of the food material, a long baking time is usually set, which further causes the local over-ripening of the food material, and even the scorching phenomenon.
