Definitions

  • the invention relates to an air inlet that allows air to be guided between a first housing opening and a second housing opening or between the first housing opening and a third housing opening. It also relates to an arrangement which has a housing, a first and a second air guiding device.
  • Heating devices for example stoves
  • the air which is supplied to the combustion chamber is expediently not taken from the immediate surroundings, for example the room in which the stove is located, but from the surroundings of the building in which the room with the stove is located.
  • air outlets are known which are inserted into the wall and are intended to enable air entry and / or air outlet through the wall.
  • the wall can be a wall.
  • Heaters can have an air chamber above the combustion chamber, in which air is heated by the heat generated during combustion. Cold air can be introduced into the air chamber and heated air can be removed from the air chamber via one or more openings. Ventilation grilles are known for covering the wall openings. On the one hand, the ventilation grille secures the wall opening against unauthorized interventions, on the other hand, the ventilation grille also allows regulation of the heat emission to the environment.
  • an air inlet and outlet which has a housing with a first region and a second region. In the first area there is a housing opening which can be opened or closed by means of a closure.
  • a duct for guiding the air can connect to the air outlet. If the air outlet serves as an air inlet, the air that has entered the duct via the air inlet can be guided to a target, for example the heating device.
  • the housing of the in DE 20 2010 001 764 U1 described air inlet or outlet leads the air straight from the front of the housing to its back or vice versa. If the air is to enter a duct, the duct must start at the rear of the housing. Is the Channel, for example, for structural reasons, not on the back, so the connection of the channel to such an air passage can only be implemented in a structurally complex manner.
