An oven frame is formed by interconnected back, side, top and bottom walls, and at least one opening at the front thereof for receiving a door. An inner cover is mounted in spaced relation to the top wall to form a top air channel, with fan means being positioned in the channel. Plate means are vertically positioned at each side of said enclosure and spaced from the side walls so as to define therewith outer air channels in air flow communication with the top air channel. Heating means are positioned in the outer channels and spaced from the plate means to accommodate air flow on either side thereof. Inner walls are spaced inwardly from the plates and define therewith inner flow channels communicating with said outer channels through bottom openings in the plate means. The inner walls are formed with openings through which heated air can pass from the inner channel to the enclosure. Air guide means are mounted on the inner surface of the inner walls, and aligned with and covering the openings formed in the inner walls and having open inner ends through which the heated air can pass into said enclosure.
