Definitions

  • L uftauslassdüse an air conditioner having a rectilinear axis air duct for generating an air jet to be installed in a wall opening of an air distribution box.
  • Air outlet nozzles of this type are known, for example, from DE-OS 1 679 564 and DE-OS 2 754 869. They are provided in large numbers next to one another in wall openings in an air distribution box and serve to distribute the air to be air-conditioned according to a desired pattern individual air jets generated by them. The desired flow pattern with an induction effect on the surrounding air can be achieved through the adjustability of the air outlet nozzles.
  • the adjustability of the direction of the outflow or the outflow position means that a part of the air outlet nozzle protrudes considerably beyond the outer surface of the associated air distribution box, and the surface of the room to be ventilated is correspondingly structured in an often undesirable manner, so that there is an adverse aesthetic effect or a surface that is difficult to keep clean.
  • the arrangement of the air outlet nozzles on inwardly inclined or recessed surfaces of the air distribution box cannot completely eliminate this disadvantage.
  • the invention has for its object to find an air outlet nozzle of the type mentioned, which after installation in a wall opening of an air distribution box does not protrude or does not protrude significantly beyond its outer surface, so that this outer surface is easy to clean and the air outlet nozzle has the appearance of the surface of the ventilating room changed less.
  • the air outlet nozzle should enable the outflow direction to be adjusted.
  • An air outlet nozzle according to the invention can be installed in differently designed air outlet boxes, which can be arranged in different ways on or in the space to be ventilated.
  • a wall of an air distribution box having numerous air outlet nozzles can run flush with the surrounding room wall, so that there are no parts protruding from the surface of the room wall.
  • air outlet nozzles according to the invention can also be provided on side walls of an air outlet chamber, which protrude into the space to be ventilated, so that these side walls nevertheless have a surface that is not or only slightly profiled.
  • the air duct of the air outlet nozzles advantageously has an elliptical cross section, such that its opening edge is circular despite the course of the air duct channel inclined to the plane of the opening edge.
  • one or more air distribution boxes 2 are attached to the false ceiling 1, to which air is supplied from a central air conditioning system via pipes, not shown, laid behind the false ceiling, for which each air distribution box 2 has a supply air nozzle 4 opening into its upper end cover 3 .
  • the air distribution box 2 has the shape of a ceiling cladding plate 14, which form the ceiling cladding side by side, as is indicated in FIG. 2 by dashed lines.
  • the underside 5 of the air distribution box 2 is preferably in the same plane as the underside 5 'of the adjacent ceiling cladding panels 14.
  • circular nozzle receiving openings 6 are provided in a row running parallel to its edge, into each of which an air outlet nozzle 7 or 7 ′ according to the invention is inserted.
  • the air outlet nozzles 7, 7 ' have a cylindrical, elongated hollow shape and accordingly surround an air duct 9 through which the air flowing through is directed in a jet shape.
  • the diameter of the air duct 9 is, for example, 10 to 16 mm.
  • the air outlet nozzle 7, 7' is chamfered at an angle of, for example, 15 to 45 °, so that it is at a corresponding angle to the flat underside 5 of the Air distribution box 2 runs. With the same At an angle eC, the air flows out of the air outlet nozzle 7, 7 'and thus out of the air distribution box 2 in the direction of the arrows 13.
  • the beveled outlet-side end of the air outlet nozzle 7, 7 ' has a circular circumferential guide edge 15 or 16, which is enclosed by the nozzle receiving opening 6 of the air distribution box 2 with little play, so that the nozzle receiving opening 6 rotatably supports the air outlet nozzle.
  • the air outlet nozzle 7, 7 ' can consequently be rotated about the axis of the circular nozzle receiving opening 6 by means of a rod-shaped tool inserted into the air duct 9, so that the outflow direction 13 can be set in any direction, but with a constant angle of inclination.
  • the air duct 9 of the air outlet nozzle 7, 7 ' preferably has an elliptical cross-sectional shape, as indicated by the dashed lines 17 in FIG.
  • the longer axis of this elliptical cross-sectional shape runs parallel to the plane of the beveled nozzle end or parallel to the plane of the underside 5 of the air distribution box 2.
  • Such a preferred embodiment of the air outlet nozzle has its outlet opening 11 when viewed from below against the underside of the air distribution box 2, or against the ceiling on which the air distribution box is provided, an appearance that is circular, whereas it would be elliptical in the case of a circular cross-sectional shape of the air duct 9, as is indicated in FIG. 1.
  • the circular appearance is aesthetically preferred.
  • connection of the air outlet nozzles 7, 7 'to the air distribution box 2, or their mounting on the edge of the nozzle receiving openings 6, can be carried out in various ways.
  • an outer groove 18 is provided, which is directed parallel to the plane of the beveled nozzle end and into which the edge of the nozzle receiving opening 6 engages.
  • the outer edge bead 10 delimiting the groove 18 is removed by the air insert nozzle 7 when it is inserted into the nozzle receiving opening 6 Inside of the air distribution box 2 from elastically deformed.
  • an edge bead 10 protruding beyond the outer surface of the air distribution box 2 is avoided, and a termination flush with this outer surface is made possible by a holding means 12 provided in the interior 19 of the air distribution box 2, which, for example, consists of an elastic pressure element, ie a spring exists, which presses the air outlet nozzle 7 'with a stop 22 projecting from it against the inner edge of the wall opening 6 of the air distribution box 2.
  • This stop 22 can consist of a circumferential inner bead.
  • FIG. 5 shows a partial illustration of an embodiment in which an engagement groove 18 'is provided between an outer edge bead 10' and an inner circumferential locking lip 20.
  • the air outlet nozzle 7 "according to FIG. 5 can thus be pressed from the outside into a nozzle receptacle opening 6 of an air distribution box 2, so that the latching lip 20 springs radially inwards and then engages behind the edge of the nozzle receptacle opening 6.
