Abstract
An oven door assembly of a shield-type construction for vented oven doors is achieved by ceramic barrier plates which can be produced in an extrusion process and which are mounted to supports, preferably in the form of cantilever beams fixed with one end to the oven door body and bearing clamps at the other end for clamping the ceramic barrier plates. Each ceramic barrier plate is replaceable and has grooves on the upper and lower side faces to receive the clamps. The clamps are constructed for clamping the ceramic barrier plates by pressure forces acting normal to the upper and lower side faces of the ceramic plates.
