Abstract
When a user manually opens/closes the door of the drawer-type heating cooker, a pulse generation means attached to an electric motor generates pulses for counting the number of revolutions. A determination means determines whether the door is opened/closed manually or not on the basis of detection of the pulses. A prediction means predicts whether the manual operation is door opening or door closing in response to the status of position detection switches for detecting the position of the door. A motor control means decides the rotation direction of the electric motor in accordance with the prediction by the prediction means and controls the rotation of the electric motor on the basis of the decision. Hence the burden of door opening/closing operation is alleviated with the help of the driving force of the electric motor even when both hands of the user are occupied.
