The invention relates to a method for realizing heat balance of equipment for preparing food by utilizing hot air. The equipment for preparing food by utilizing hot air comprises a pot and a food preparation chamber (1) arranged in the pot, wherein a hot air channel (9) is formed between an inner vertical wall (5) of the pot and the food preparation chamber (1). An upper surface of food in the food preparation chamber (1) is subjected to heat radiation, the lower surface of the food in the food preparation chamber (1) is heated by hot air, and the rotation speed of a motor is automatically adjusted through electronic control so as to adjust the speed of the hot air, so that the upper and lower surfaces of the food are heated uniformly. The method provided by the invention has the technicaleffects that the rotation speed of the motor is automatically adjusted through electronic control so as to adjust the speed of the air, so that in the preparation process of the food in the equipment, the radiation heat on the upper surface and the heat on the lower surface caused by hot air circulation are balanced, thereby ensuring that the upper surface and the lower surface of the food are heated uniformly and have the same maturity.
