A cooking device according to the present disclosure comprises: a heating chamber configured to accommodate an object-to-be-heated; a circulation fan configured to suck air in the heating chamber and blow the sucked air into the heating chamber; a heating chamber internal flow path forming unit disposed inside the heating chamber and configured to define the flow rate and the blowing direction of the air blown into the heating chamber by the circulation fan; and an internal temperature sensor disposed in a circulation path of the air and provided in a region apart from the heating chamber internal flow path forming unit by a predetermined distance, the circulation path being formed inside the heating chamber by the heating chamber internal flow path forming unit.

Cooking device

A heating cooker includes a heating chamber, a heating portion, a brushless motor, a body control circuit, a DC power supply circuit, a motor control circuit, and a safety device. The brushless motor drives a rotary drive mechanism included in the heating portion. The body control circuit outputs a drive signal for the brushless motor. The DC power supply circuit supplies DC power to the brushless motor. The motor control circuit controls the driving of the brushless motor in response to the drive signal. The safety device includes a rotation detection element to detect the rotation state of the rotor of the brushless motor and output a rotation detection signal, and a switch for blocking a power supply line connected to the DC power supply circuit. The safety device controls the switch in response to the rotation detection signal and drive signal.
