  • the air diffuser only has the perforations after the housing has been placed on the cladding panel, i.e. a corresponding perforated sheet (of a grid ceiling or wall cladding).
  • the air guiding elements are arranged in front of the air outlet surface, viewed in a flow direction. This means that the air guiding elements extend into the interior space enclosed by the housing.

  • air outlets are already known from the prior art and are used to introduce fresh air into a room.
  • the air outlets known from the prior art usually have a ceiling panel arranged at the air outlet surface or are mounted on such a panel from above.
  • Various air guide elements can be used to create an outflow from the air outlet surface parallel to the ceiling.
  • the German patent application DE 10 2014 109 927 A1 Describes an air vent with at least three air guide elements, each of which is arranged adjacent to one another.
  • the air guide elements are arranged in a circle around an axis and thus encircle a center point.
  • Each air guide element overlaps the adjacent air guide element, forming an air guide channel between the adjacent air guide elements.
  • the circularly arranged air guide elements create a jet deflection, i.e., a redirection of the supply air flow.
  • a disadvantage of the devices known so far is the large overall width of the air outlets, which results from the need for a predetermined inflow zone.

Furthermore, the aim is to achieve an air flow as parallel as possible to the cladding panel.
  • the air passage according to the invention is characterized in that the air guiding elements are arranged one behind the other in the form of a row, wherein at least one air guiding element is inclined in a first direction relative to the air outlet surface and at least a second air guiding element is inclined in a direction opposite to the first direction. set second direction is inclined relative to the air outlet surface, whereby - viewed in a direction perpendicular to the air outlet surface - the air flowing through the air outlet is discharged in directions 180 degrees +/- 5 degrees opposite. In this way, the air leaving the air outlet from the first and second air guide elements is blown out into the room in opposite directions, with the two directions being rotated by 180 degrees +/- 5 degrees.
  • the air guiding elements are arranged mirror-symmetrically to one another with respect to a vertically aligned central plane of the housing running parallel to a longitudinal direction of the air outlet.

  • a vertex of an acute angle of inclination of the at least one second air guide element is preferably arranged correspondingly in one region, i.e., near an opposite, elongated side wall of the housing. This means that - viewed in the cross-section of the air outlet - a distance between the respective air guide element and the air outlet surface is smaller at a side wall than in a central region of the air outlet.
  • the advantage of the air outlet according to the invention is that an air flow can escape from the air outlet over large areas of the air outlet surface in the direction of two opposite, preferably elongated side walls, preferably at least substantially parallel to the ceiling.
  • the total width of the The air outlet can thus be reduced compared to the devices known from the prior art.
  • two adjacent air outlets, each of which causes the supply air to flow out in opposite directions can be dispensed with, since the air outlet according to the invention already achieves an outflow of the supply air in two directions. Consequently, the air outlet according to the invention can achieve an outflow of the supply air in two directions, even though the air outlet is narrow in contrast to the air outlets known from the prior art.
  • the air vent according to the invention can preferably have a width between 5 cm and 50 cm, more preferably between 10 cm and 30 cm.
  • the height of the air vent according to the invention depends on the desired air volume and can preferably be between 10 cm and 50 cm.

It would also be conceivable for adjacent air guide elements to have different widths, so that the same outflow direction can be achieved over larger or smaller distances, depending on the circumstances. It is clear that the orientation of the air guide elements can be individually selected and planned.
  • the invention provides that a plurality of preferably all air guide elements, inclined in the first direction and/or in the second direction, are each formed jointly by a strip-shaped, sawtooth-shaped component, preferably made of a sheet metal or plate, which preferably interlock in a comb-like manner.
  • the respective sawtooth-shaped component preferably forms a type of tooth comb, wherein the respective air guide elements, which are inclined in the same direction, together form a tooth comb.
  • Two components can preferably be separated from a sheet metal or plate by splitting the sheet metal or plate in a sawtooth shape, for example in the middle.
  • a first part of the split sheet metal or plate preferably has a plurality of air guide elements spaced apart from one another and inclined in the same direction to the air outlet surface.

  • the separating line forms a cutting edge, e.g., of a punching tool, at which the components are separated from one another.
  • At least one, preferably all, air guiding element or air guiding elements inclined in the first direction are movable relative to at least one, preferably all, air guiding element or air guiding elements inclined in the second direction, preferably in one direction perpendicular to the direction of the row of air guide elements and/or parallel to the air outlet surface. Due to the mobility of the air guide element or elements in a direction perpendicular to the direction of the row of air guide elements, the distance between two air guide elements with opposite inclinations can be changed in a direction perpendicular to the longitudinal axis of an air outlet.
  • the air guide elements can therefore be nested more or less inside each other. This allows the flow behavior to be adapted depending on the application. For example, the air outlet surface through which the air flows can be enlarged or reduced. Likewise, a shift in a direction parallel to the air outlet surface can be advantageous, as this also allows the flow behavior to be adapted depending on the application.
  • an angle of inclination of at least one air guide element, preferably all air guide elements, relative to the air outlet surface is formed by a plane spanned by the respective air guide element and the air outlet surface.
  • the acute angle of inclination preferably points toward a side wall, preferably the elongated side wall, of the air outlet.

  • An advantageous further development of the invention provides for the housing to be detachable from the air outlet surface formed by a perforated ceiling panel.
  • a detachable ceiling panel offers the advantage that the air guide elements can be subsequently modified, replaced, or repaired while the ceiling air outlet is installed.
  • the ceiling panel also provides a visual barrier.

  • a web between two air guide elements aligned in the same direction simplifies handling during assembly of the air outlet.
  • the air guide elements, inclined in one direction, with their webs, thus resemble a comb with a long A web and teeth extending from it.
  • Manufacturing is also particularly easy, especially when cutting a sawtooth-shaped component from a sheet or panel, if a strip is arranged between the two air guide elements. This eliminates the need to separate the air guide elements.
  • the air outlet area can be reduced in relation to the perforated ceiling panel, at least in the edge areas. This improves the flow behavior.
  • At least one air guide element preferably all air guide elements, has or have a bending axis arranged perpendicular to a longitudinal axis of the air outlet, wherein the respective air guide element can be bent or folded along this bending axis in the direction of the air outlet surface.
  • the bendability or folding of the respective air guide element allows the outflow of the supply air from the air outlet to be modified.
  • a particular air guide element it would be conceivable for a particular air guide element to have a flat, curved, beveled, or flat cross-section.
  • the appropriate air guide element can be selected depending on the desired airflow pattern.

  • the air flow can thus be precisely divided and discharged in the two intended directions.
  • a wall is arranged at least between two adjacent air guide elements, preferably oriented in different directions.
  • a wall is located between all adjacent air guide elements. This can improve the flow behavior of the supply air from the air outlet. Vortex flows in the immediately adjacent areas of two air guide elements oriented in different directions can be avoided with the help of the walls and the resulting spatial separation of the air guide elements.
  • a further alternative development of the air passage according to the invention provides that at least one air guiding element has a slot on at least one side which is arranged adjacent to another air guiding element, wherein the slot preferably allows a displacement of the air guide element in a direction parallel to the direction of the row of air guide elements, so that preferably two adjacent air guide elements can be pushed into one another at least partially.

  • the respective slot is preferably arranged on one or both sides of the respective air guide element.
  • a flow cross-section formed between an air guide element and the air outlet surface can be closed by means of a partition element, which is preferably oriented perpendicular to the air outlet surface and/or is movable in a direction perpendicular to the air outlet surface, such that a gusset space located between the relevant air guide element and the air outlet surface is separated from the supply air guided through the connection piece into the interior of the housing.
  • a partition element which is preferably arranged directly on the air outlet surface, the rear part of the air outlet surface and the corresponding air guide element, viewed in the direction of flow, namely the gusset space, is closed off. The supply air is thus blown into the room in a vertical direction.
  • the partition element opens and thus frees the flow cross-section through the interstices, resulting in an increasingly horizontal outflow.
  • Cold supply air is then blown horizontally along the ceiling into the room and "trickles" slowly, i.e., at a low falling speed, into the room. This creates a pleasant, draft-free indoor climate.
  • the at least one air guide element is an injection-molded element. Injection-molded elements can be manufactured very quickly and in large quantities. Furthermore, production costs can be reduced in this way.
