Definitions

  • the invention relates to an inductive passage with at least one slot-shaped inlet opening and at least two outlet openings.
  • the outlet openings are delimited on both sides by a bluff body.
  • the layout of the latter is adapted to the cross section of the inlet opening and, following the direction of flow, is arranged at a vertical distance from the plane of the inlet opening.
  • Such induction passages are generally known and are preferably arranged in the ceiling area of a room to be ventilated and / or air-conditioned and are connected to an air duct system. Due to the shape of these passages, the emerging air jets receive a high momentum and are thus able to mix intensively with room air before they reach the lounge area of the room, so that drafts are avoided there.
  • inductive diffusers made of plastic have two major disadvantages: Inductive diffusers made of plastic with sufficient temperature resistance, whereby the diffusers can catch fire depending on the plastic used for their manufacture. On the other hand, inductive diffusers made of plastic can only be given a coat of paint with difficulty and can therefore only be adapted to the individual color spectrum of a room with great effort.
  • the invention has for its object to propose an induction diffuser of the type described above, which can be produced at least as efficiently as the known induction diffusers and also has the advantages that it is characterized by a high fire resistance and is efficient and durable with an individual paint can be provided.
  • an embodiment of the invention provides that one longitudinal edge of the tongues forming the inlet opening abuts one longitudinal edge of the tongues delimiting the outlet openings.
  • the two components forming the inductive passage can be sufficiently firmly clamped to one another if, according to a further embodiment of the invention, at least one center piece of the two opposite edge regions of the sheet metal plate defining the inlet opening, which run perpendicular to the longitudinal extent of the inlet and outlet openings, in the direction of the sheet metal plate defining the outlet openings Is angled 90 ° and the legs thus formed are at a vertical distance from one another which corresponds to the longitudinal extent of the tongues delimiting the outlet opening.
  • the side edges of the tongues delimiting the inlet opening can abut against the legs of the edge regions of the sheet metal plate defining the inlet opening under a press fit. It is of course within the scope of the invention to provide small protrusions or depressions on the lateral edges of the tongues which delimit the inlet opening, which protrusions corresponding to depressions or protrusions of the adjacent legs.
  • a sheet-metal strip which is bent in the shape of a roof and which is produced as an additional component can be arranged between the legs.
  • the sheet metal strip is intended to overlap a sheet metal web between the two outlet openings and to form a bluff body which is triangular in cross section.
  • the flow paths through the inductive passage thereby receive a diffuser-like cross section, as is known per se from inductive passages made of plastic by injection molding.
  • an embodiment of the invention provides that the sheet metal plates have a substantially square outline. If the angled sheet metal plates essentially maintain the square outline, inductive passages designed in this way can be arranged in rows, the longitudinal extensions of the inlet and outlet openings of an inductive passage being able to be rotated by 90 ° to those of adjacent inductive passages.
  • the exit planes of the air jets of an inductive passage can intersect with the exit planes of the air jets from neighboring inductive passages, as a result of which the mixing of both the supply air jets with one another and their mixing with room air is promoted in a highly effective manner.
  • the inductive passage is provided with an inlet opening 1 and two outlet openings 2, which are connected via a flow path 3 which is Y-shaped in cross section.
  • the mutually facing sides of the two outlet openings 2 are delimited by a bluff body 4 which is adapted to the cross section of the inlet opening 1 and is arranged at a distance from the plane thereof so that the bluff body 4 is flush with the two outlet openings 2 on the outside.
  • the inductive passage is composed of two sheet metal plates 5 and 6 and a sheet metal strip 7.
  • the sheet metal plate 5 forms a frame for the inlet opening 1 and for this purpose is double-T-shaped slotted, two tongues 8 thereby formed being bent over a radius in the direction of the outlet openings 2.
  • Center pieces of parallel edge regions of the sheet metal plate 5, which run perpendicular to the longitudinal extent of the inlet opening 1, are bent through 90 ° in the direction of the sheet metal plate 6 and form legs 9, the distance from which corresponds to the width of the tongues 8.
  • the sheet metal strip 7 bent in the shape of a roof angle is also arranged between these legs.
  • edge strips 10 of the sheet metal plate 5 which extend parallel to the longitudinal extent of the inlet opening 1 are also bent at right angles in the direction of the sheet metal plate 6.
  • the outlet openings 2 are formed by two mirror-inverted U-shaped punched-outs, tongues 11 being bent towards the inlet opening 1 in such a way that edge edges of the tongues 8 abut against edge edges of the tongues 11 and thus a smooth transition within the flow path 3 arises.
  • Edge strips 12 of the sheet metal plate 6 are angled in the direction of the sheet metal plate 5 so that they are aligned with their angled edge strips 10.
  • the sheet metal plate 6 forms a sheet metal web 13 between the outlet openings 2 Underside of the bluff body 4 completed by the sheet metal strip 7.
  • the three components of the induction diffuser according to the invention can therefore be rationally produced in a punching and bending process and are to be rationally provided, for example, in the diving operator with the individually desired color.
  • the square layout of the induction diffuser allows an arrangement that is optionally rotated by 90 °, for example within an appropriately designed grid ceiling.
