Heating cooker

A heating cooker comprising:

• a cooking container housed in a heating chamber inside a device main body;
• and
• a single blade connected to a rotation axle of a reversible rotation drive motor through an opening therein and rotating in first and second rotation directions around the rotation axle in the cooking container to stir a heating-target object put in the cooking container,
• the single blade including a first functional portion pressing the heating-target object toward a side wall of the cooking container when rotating in the first rotation direction, and a second functional portion pressing the heating-target object not toward the side wall of the cooking container when rotating in the second rotation direction,
• wherein the first functional portion has an inclined surface having an inclination angle progressing gradually larger relative to a horizontal direction from the rotation axle of the single blade toward a rotation tip position of the single blade, and
• the second functional portion on an opposite side of the single blade from the first functional portion and having an inclined surface having a concave shape curved toward an inside of the single blade relative to a straight line connecting an upper end portion and a lower end portion as seen in a vertical cross section,
• wherein a rotational inclination angle of the second functional portion in the horizontal direction as seen in a plan view progresses gradually smaller from the rotation axle of the single blade toward the rotation tip position and then progress gradually larger in the direction toward the rotation tip position, such that a rate of change of inclination increases at the rotation tip position,
• wherein the single blade has a flat upper surface having a horizontal surface area progressing gradually smaller from the rotation axle to the rotation tip position.
