Definitions

  • the invention relates to an air inlet which enables the guidance of air between a first housing opening and a second housing opening or between the first housing opening and a third housing opening.
  • Heating devices such as ovens
  • the air that is supplied to the combustion chamber is not expediently taken from the immediate surroundings, such as the room in which the oven is located, but from the surroundings of the building in which the room with the oven is located.
  • Air vents are known for guiding air through a wall of the room or building. These are set into the wall and are intended to allow air to enter and/or exit through the wall.
  • the wall can be a brick wall.
  • Heating devices can have an air chamber above the combustion chamber in which air is heated by the heat generated during combustion. Cold air can be fed 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 wall openings. The ventilation grilles protect the wall opening against unauthorized interventions and also allow the heat to be released into the environment to be regulated.
  • An air inlet and outlet which has a housing with a first area and a second area. 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 be connected to the air outlet. If the air outlet serves as an air inlet, the air entering the duct via the air inlet can be guided to a destination, for example the heating device.
  • the housing of the DE 20 2010 001 764 U1 The air inlet or outlet described above directs the air straight from the front of the housing to the back or vice versa. If the air is to be directed If the air flow is to enter a duct, the duct must begin at the back of the housing. If the duct is not at the back, for example for structural reasons, then connecting the duct to such an air outlet is very difficult to achieve.
  • US 2005/0011218 A1 discloses an air passage having an inner part and an outer part.
  • the inner part is arranged rotatably in the outer part.
  • the object of the invention is to eliminate the disadvantages of the prior art.

To do this, it is only necessary to change the position of the second air guide device in the housing.
  • the second air guide device is not a moving part. It is fixed in the housing so that it cannot move. Switching between the second housing opening and the third housing opening is not provided.
