The present invention relates to heating cookers, particularly to a structure for ventilation and cooling of microwave ovens employing a range hood. The structure according to the present invention enhances the ventilation airflow and capacity of a heating chamber by enlarging diameter of a ventilating fan by forming a recess on an upper wall of the heating chamber and by disposing the ventilating fan in the recess. Also, an improvement in ventilation efficiency is achieved by disposing the ventilating fan of a larger diameter at either or both ends of a wave-guide, and dividing the airflow path into an evenly well balanced plurality of airflow paths. Moreover, an openable door is attached to either or both of an exhaust opening and an intake opening for the air to pass through an inner surface of the door, thereby keeping the soiled surface inconspicuous. Furthermore, a cooling fan for a machinery compartment is disposed on an upper part of the machinery compartment in order to widen the airflow path for further improvement of the cooling and ventilation efficiency.
