Definitions

  • the invention relates to an air outlet grille, which is particularly suitable for ovens, and an oven with such a Heilauslassgitter.

  • Such hot air outlet grille are referred to as a ceiling grid when they are arranged in a horizontal mounting position on the furnace roof.
  • DE 35 01 289 C2 discloses a ceiling grid intended for installation in the ceiling of a tiled stove.
  • the ceiling grid described therein has a rectangular outlet opening, are arranged in the parallel, pivotable blades.
  • the slats make it possible to close or open the outlet opening by changing the angle of attack of the slats.
  • the slats are mounted in a rectangular frame, which consists of two longitudinal and transverse profiles, which in turn have horizontal and vertical legs. At the transverse profiles, the slats are pivotally mounted about axes which lie in a common horizontal plane. The position of the slats should allow not only to change the strength of the air flow, but also its direction.
  • a ventilation grille which can be used in a designated frame as a frame.
  • the ventilation grille can be used by means of plug-in, latching or locking elements.
  • the ventilation grille can thus be removed from the insert frame.
  • the ventilation grille itself consists of a frame called a diaphragm web, which encloses a receiving opening. Swivel-mounted slats are attached to this ventilation grille frame, which can close or open the receiving opening depending on the angle of attack. Also required is a Aufsetzrahmen that is to allow a flush finish between insert frame and oven wall.
