Definitions

  • the invention relates to a floor outlet which essentially consists of a cylindrical housing which can be inserted into a floor opening and a circular plate which covers the housing and is provided with outlet openings. Under this a disc is mounted adjustable in height, with which, depending on its position, cross sections of the outlet openings can be completely blocked or released.
  • the cylindrical housing is provided with a radially outwardly widening collar which merges into a flange resting on the edge of the floor opening.
  • a funnel-shaped insert with a truncated cone-shaped jacket is arranged concentrically within the housing.
  • the outside of this casing and the inside of the housing delimit an annular space which is narrowed in the plane of the flange arranged on the collar of the housing by a flange which projects radially outwards and which is arranged on the insert.
  • the exit cross-section of the insert can be blocked up to an annular gap by a height-adjustable disc.
  • the floor outlet has the effect of a floor source outlet in which the supply air is blown into the room essentially horizontally.
  • the effect of a floor swirl outlet cannot be achieved, through which the supply air is blown essentially vertically into the room.
  • a bottom outlet is also known from EP 0 446 557 A3, which is provided in a circular plate covering a housing with obliquely upwardly directed outlet slots.
  • the plate is formed from a pair of plates, the outlet slots in the individual plates being inclined in opposite directions. By a slight relative rotation of the individual plates, the outlet slots can be positioned correspondingly offset from one another, which enables a limited change in the outflow direction of the supply air jets.
  • the invention is based on the object of designing a floor outlet of the type described at the outset in such a way that it combines the blow-out properties of outlets designed as a floor source outlet and as a floor swirl outlet.
  • the floor outlet can be operated temporarily as a floor source outlet with a substantially horizontal blow-out direction and at times as a floor twist outlet with a vertical blow-out direction by a corresponding height adjustment of the plate .
  • the plate must be lowered for the source outlet characteristic so that all outlet slots can be flowed through freely, while for the swirl outlet characteristic the plate is raised so that the slots arranged on the inner pitch circle are blocked and only the slots arranged on the outer pitch circle can be flowed through.
  • the outlet cross sections of the slits crossing the outer pitch circle are narrowed in their width by strips molded onto the plate, each of these slits being associated with a strip on the longitudinal reveal, which is oriented inclined to the entry cross section of the slot.
  • the strips When operating the floor outlet as a floor source outlet, the strips favor a deflection of the flow into the horizontal, the air jets emerging as a result of the Koanda effect being deposited on the floor of the room to be ventilated. At the same time, the air jets which exit through the slots assigned to the inner pitch circle are deflected in their direction by the horizontally emerging air jets. If the floor outlet is operated as a swirl outlet, no air jets emerge from the slots assigned to the inner pitch circle, so that a negative pressure is created within this central area, as a result of which the air jets are deflected in the vertical direction despite the strips and unite. The supply air flows steeply upwards through the total jet generated in this way.
  • an embodiment of the invention provides that each of the slits crossing the outer pitch circle defines a convex arc in the area of the inlet cross section with a longitudinal reveal that is oriented inclined away from the inlet cross section.
  • the bottom outlet which can be inserted into a bottom opening (not shown) and ends flush with the bottom surface, comprises a cylindrical housing 1 which is provided with a conventional throttle device, which is therefore not shown in detail, for the total volume flow to be fed to the bottom outlet.
  • a likewise cylindrical dirt trap 2 of conventional design is used in the housing 1.
  • the housing 1 is covered on the ceiling side with a circular plate 3 which forms an outlet body.
  • a disc 4 is mounted in a manner known per se on a spindle 5 which is coaxial with the plate 3 so that the disc 4 lies tightly against the underside of the plate 3 in its upper position or can be displaced into the lower position shown.
  • the plate 3 is provided with radial slots 5 and 6, the slots 5 being assigned to an outer pitch circle 7 in a uniform distribution and the slots 6 being assigned to an inner pitch circle 8 in a uniform distribution.
  • the slots 5 and 6 are delimited by inclined longitudinal soffits 9 and 10. Deviating from the slots 6, an outlet cross section 11 is narrowed for each slot 5 by a bar 12 molded onto the plate 3, which projects beyond the plane of the longitudinal reveal 9. An inlet cross-section 13 is widened by the longitudinal reveal 10, which runs downward in a convex arch 14.
