Abstract

Gas cooking appliances having glass or glass-ceramic plates for cooking surfaces also having gas-radiation burners that are positioned below the plate or atmospheric burners that are recessed in the plate. With gas radiation burners, care must be taken to ensure a thermally advantageous discharge of exhaust gases that are produced and with atmospheric burners, care must be taken to ensure an adequate supply of primary air. Accordingly, the glass or glass-ceramic plate forming the cooking surface is partially bent out of the cooking surface plane to form an adhesive-free exhaust air duct or fresh air opening in the bent area. The exhaust air duct and fresh air opening are free of ventilation lattices.
