Abstract
A drawer-type cooking device and a method for controlling opening and closing of a door thereof, in which an opening/closing direction and an absolute position of a door by a manual opening/closing operation by a user can be detected with a simple structure even when the door is in a door-open state in an intermediate position, is provided. A rotation sensoris disposed in relation to an output shaft of a motorfor driving a door capable of opening and closing an opening of a cooking device body in an opening/closing direction. A microcomputercontrols drive of the motorincluding a rotation direction by receiving an input of a detection signal of the rotation sensor,which is a sensor for generating two rotation pulses having different phases (for example, pulse train signals with a 120-degree difference) from the motor. A control device can determine the rotation direction of the motorbased on the two rotation pulses therefrom.
