The function of heating and cooking the food to be cooked W on the top 14 stops both the rotary plate 13 and the rotary plate 14 of the drive motor 12 by operating the rotary plate stop button 5C of the operation panel 5. As a result, uneven heating occurs, making it difficult to uniformly heat and cook the food W.

The present invention was made in view of the above-mentioned circumstances, and the present invention is made by heating and cooking while rotating a rotating plate that also functions as a stirrer fan function (radio wave stirring blade) even when the rotating plate inside the open door stops rotating. It is an object of the present invention to provide a heating cooking device that eliminates heating unevenness and uniformly heats and cooks food.
