ABSTRACT:
A hot air circulating cooker includes a box-like casing defining a heating chamber. A rear plate of the casing has suction holes at its center portion and upper and lower discharge holes located above and below the suction holes. A cover is fixed to the outer surface of the rear plate to define a storing chamber. A fan is arranged in the storing chamber to face the suction holes. When being rotated in a predetermined direction, the fan draws air in the heating chamber into the storing chamber through the suction holes, flows the drawn air in the predetermined direction, and discharges the air to the heating chamber through the discharge holes. An upper airflow-directing mechanism is provided in the storing chamber so as to guide part of the air flow to those of the upper discharge hole which are located at an upstream side of the air flow in the storing chamber. A lower airflow-directing mechanism is provided in the storing chamber so as to guide part of the air flow to those of the lower discharge holes which are located at an upstream side of the air flow in the storing chamber.
