Heating cooker

A heating cooker comprising:

• a heating chamber configured to accommodate an object to be heated;
• a heater configured to heat the object to be heated in the heating chamber;
• a brushless motor being a drive source of a rotary drive mechanism included in the heater;
• a body control circuit configured to output a drive signal for the brushless motor;
• a direct current (DC) power supply circuit configured to supply a DC power to the brushless motor;
• a motor control circuit configured to control a driving of the brushless motor in response to the drive signal;
• and
• a wired logic circuit including:
• a first abnormality detection circuit;
• a second abnormality detection circuit;
• a first sensor configured to detect a rotation state of a rotor of the brushless motor, and to output a first rotation detection signal;
• a second sensor configured to detect the rotation state of the rotor of the brushless motor, and to output a second rotation detection signal;
• a first switch coupled to a power supply line in series, the power supply line being coupled to the DC power supply circuit, the first switch being configured to block the power supply line;
• and
• a second switch coupled to the power supply line in series, the second switch being configured to block the power supply line,
• wherein the first abnormality detection circuit is configured to control the first switch in response to the drive signal and the first rotation detection signal, and
• wherein the second abnormality detection circuit is configured to control the second switch in response to the drive signal and the second rotation detection signal.
