Definitions

  • the present invention relates to a stovepipe.
  • the oven must be heat-resistant to withstand the temperatures that occur during baking or cooking. Even in the baking or cooking mode from the food leaking water vapor must not damage the oven. Furthermore, customers want automatic self-cleaning, such as ecolysis or pyrolysis. If residues remain in the oven despite automatic self-cleaning, then a non-stick coating is favorable, which allows easy manual cleaning of the oven. Last but not least, the oven or the oven should work energy-efficiently.

  • the second wall flat part has a second material defining a surface function of the second wall surface part.
  • the first and second materials have a different surface function.
  • One idea underlying the present invention is to provide a stovepipe with at least two wall flat parts which fulfill different surface functions. As a result, different functions can be easily integrated into the oven.
  • the first and second wall flat parts are preferably separate parts which are connected to one another in a form-fitting, force-fitting or material-locking manner in order to form the baking pipe.
  • a "wall flat part” is a flat part, ie such a part, in which the width and length are in each case a multiple, for example at least ten or at least a hundred times the thickness, which at least partially forms a wall of the baking tube a surface function is meant to act on a condition or process on the surface of the corresponding wall surface part.

  • thermal radiation with a wavelength of between 1 and 10 ⁇ m is emitted at a material temperature between 350 and 600 ° at least greater than 90%.
  • non-stick is meant a nature of the first and second materials to prevent stains from being burned in. Accordingly, such non-stick materials can be easily cleaned.
  • the "heating" function means that the first or second material forms a surface heating system.
