Abstract
Embodiments of the present disclosure relate to an air-based fryer, comprising: a food preparation chamber (1); a heating device (3); an airflow generating device (2) configured to enable air heated by the heating device (3) to form an airflow to heat food in the food preparation chamber (1); a first temperature sensing device (4) located nearby or on the heating device (3) and configured to detect a temperature of a surface of the heating device (3); and a controller (5) configured to control operation of the heating device (3) based on the temperature of the surface of the heating device (3) detected by the first temperature sensing device (4). The air-based fryer reduces the generation of fume by restricting the surface temperature of the heating device.
