In the implementation of the invention, the second channel is connected to the second The third and fourth openings lead to the ventilation mechanism. The second one... The channel has an angle with the vertical axis. The preferred method of the invention. In this application, this angle is between 8° and 12°. The second channel is positioned at an angle. Thanks to its positioning, the blown air is routed between the second and third panels. This prevents filling and, along with the flow rate, draws heat from the cooking chamber. It provides. In another application of the invention, the end of the second channel extending into the cover is the second It is angled so that it approaches the panel. This allows the air blown into the cover to reach the second 15 and cooking with the flow rate, preventing it from filling between the third panel. By drawing heat from the room and cooling the second panel which gets hotter, the standard It is ensured that the required temperatures are not exceeded. The second channel is angled. Thanks to its positioning, the airflow speed increases, resulting in a higher efficiency than the second panel. By extracting excess heat, the grilling function is activated at 20°C with the lid closed. It is made possible to operate it. This invention eliminates the problem that occurs when the grill is burning with the lid closed in gas built-in ovens. While problems such as flame elongation, flame extinction, and emissions are being resolved. The temperature increase occurring in the oven door panels is reduced by 25 without any additional cost. This is resolved. Also, thanks to the top part of the cover, the operation of the ventilation fan is controlled. The efficiency is also increased. This allows the unburned gas inside the furnace to be released into the environment more efficiently. While easily expelled, the stoichiometric ratio (air-gas) required for efficient combustion is also maintained. (mixture) is provided.
