<p>PROBLEM TO BE SOLVED: To early detect a rotation abnormality of a circulation fan in a heating cooker that cooks an object to be cooked by circulating hot air generated by an oven burner in a heating chamber.SOLUTION: A heating cooker comprises a circulation fan and a motor 4 for rotating the circulation fan, and is provided with a drive control unit 105 for driving the motor 4, a drive characteristic detection unit 106 for detecting a drive characteristic of the motor 4, a storage unit M for storing a threshold value of the drive characteristic of the motor 4 for determining a rotational state of the circulation fan; and a fan state determination unit 107 for determining the rotational state of the circulation fan by comparing the drive characteristic detected by the drive characteristic detection unit 106 with the threshold value of the drive characteristic.</p> |
