PROBLEM TO BE SOLVED: To provide a heating cooker which is prevented from generation of abnormal noise due to friction between a turning wheel and endless winding means at the time of start-up of a heated air motor when inverting a heated air fan in a forward or reverse direction.SOLUTION: A turning direction of a heated air fan 34 connected to a heated air motor 35 is inverted in a forward or reverse direction to circulate heated air in an oven chamber 2, voltage lower than a rated voltage is applied to a second motor 35B when switching the rotation of the heated air fan 34 from a right direction to a left direction for example, and the rated voltage is applied after a prescribed period of time passes. As a result, start-up of the second motor 35B becomes gentle by increasing the applied voltage to the second motor 35B by two stages when switching the rotational direction of the heated air fan 34, and thereby power applied on pulleys 48A,48B or a belt 51 is softened. Accordingly, generation of abnormal noise due to friction of the pulleys 48A, 48B and the belt 51 is prevented when starting up the heated air motor 35 when inverting the heated air fan 34 in a forward or reverse direction. |
