PURPOSE: A method for heating a food making device using hot air is provided to preheat an object with an electric hot air heater and then re-circulate the hot air for the electric hot air heater, thereby reducing energy consumption. CONSTITUTION: A method for heating a food making device using hot air comprises as follows. An object is heated by an electric hot air heater. A hot air inlet is connected to a hot air absorption port. The hot air is re-circulated within the hot air absorption port to raise the inner temperature of the electric hot air heater. A heat-insulating material and heat-retaining body are put into a place where the hot air flows in order to maintain the heat. |
