<p>An oven door of sheet metal construction having an outer door panel, an inner door liner and an inner panel that is adapted to be exposed to the internal oven temperatures. The inner panel is of shallow pan configuration with a peripheral flange that extends into a large opening in the inner door liner. A strip of gasket material encircles the inner panel and spaces the inner panel from the inner door liner in the manner of a thermal break. An insulation guard closes the inner panel to form a closed box-like structure that is substantially filled with thermal insulating material. A cooling air channel is located between the insulation guard and the outer door panel so that currents of cooling air may pass up through the cooling channel.</p> |
