Abstract: A portable oven easily assembled without tools or fasteners from interfitted modular components is adapted to function in a convection mode. The components include a pair of electrical strip heaters disposed within a base frame that supports a plurality of upstanding wall panels which circumscribe a close having corners. A receiver mounted on the frame proximate each corner is recessed to releasably receive a free end of an upstanding stanchion. Each stanchion is formed with a pair of open channel members positioned orthogonally on the stanchion to face corresponding ones of channel members of opposite stanchions for slidably receiving a wall panel between the members in releasably captive relation. A removable cover is positioned in registry with the upstanding stanchions and wall panels to define a closed heating chamber. Heated air is circulated within the oven via apertures in a floor panel of the frame and a blower assembly mounted upon the cover in communication with the chamber.
