Definitions

  • the invention relates to a ventilation box with a Housing with an air outlet opening, at least one extending into the housing extending ventilation tube that connected to an air supply and in the control flap is arranged. Furthermore, the air outlet opening covered by a base plate made up of a perforated plate and a honeycomb insert.
  • Air inlet connection is one not described in detail Throttle valve for setting the desired one arranged amount of air arranged.
  • Throttle valve for setting the desired one arranged amount of air arranged.
  • Inside is below the air inlet pipe symmetrical to this a plate-shaped, perforated Air distribution plate arranged.
  • Another perforated Sheet is like an air jam between the Air distribution plate and an air duct chamber arranged and serves to homogenize the air flow over the air outlet surface of the housing.
  • the Air guide chamber includes a honeycomb plate with evenly distributed cylindrical channels and one on the entry side perforated plate placed on the honeycomb panel.
  • the technical problem underlying the invention is it to create a ventilation box in a simple design, where an adjustable, laminar air inflow is possible is.
  • the solution to this technical problem is to create a ventilation box of the generic type, which is characterized in that the outer surface of the Ventilation tube and the control flap perforated are, the ventilation pipe at its in the housing End has a closed bottom and the perforated plate connects to the honeycomb insert on the outlet side.
  • the invention is based on the idea of using of the perforated ventilation pipe with closed bottom and the perforated control flap arranged in the ventilation pipe to create an even distribution in the housing, which have no subdivisions into different chambers even distribution of air needed.
  • the first directional guidance of the air through the honeycomb insert and then the outflow of directed air through the perforated plate allows together with the special design of the ventilation pipe in surprising Excellent laminar air inflow, which, as various attempts have shown, about several meters from the ceiling to the floor inflows laminar without swirling.
  • Lever adjustable control flap is an adjustment of the inflowing air volume depending on the to be ventilated Room size possible.
  • pre-swirling takes place instead, the even distribution in the housing supported.
  • honeycomb insert a variety of has closely spaced channels, their cross section is circular or polygonal.
  • a good laminar air flow results at a height from 10 to 20 mm of the honeycomb insert.
  • the channels of the honeycomb insert advantageously have a diameter of 3 to 8 mm, with tests as a particularly advantageous diameter of the channels 4 mm each and a height of the honeycomb insert of 13 mm has highlighted.
  • a perforation of the control valve and the outer surface of the Ventilation pipe with the same grid and the same diameter of the openings has proven to be particularly advantageous in Combination with the honeycomb inserts mentioned and the perforated plate proven. It is advantageous if the Diameter of the opening in a range from 4 mm to 6 mm is, with a diameter of 5 mm is preferred.
  • Ventilation box from a box-shaped housing 1 made of sheet steel that is open at the bottom. Two in parallel mutually lying side surfaces of the housing 1 are in Area of the air outlet opening is bent at a right angle, around as a support for a covering the air outlet opening Perforated plate 10 to serve.
  • the perforated plate 10 has two opposite side faces two each right-angled bend.
  • a honeycomb insert 11 is inserted, which is in the manner of a Honeycomb is designed, i.e. side by side Has channels that have a circular cross section exhibit.
  • the honeycomb insert 11 is on the perforated plate 10 by means of a hold-down device 12 which is located between the honeycomb insert 11 and the U-shaped folds of the perforated plate 10 is inserted, held.
  • the box-shaped housing 1 has on its top a round opening into which a ventilation pipe 2 is inserted is.
  • This ventilation pipe consists of - as in particular Fig. 2 shows - from one of the outer surface of the Ventilation tube 2 forming perforated plate cylinder, the bottom, i.e. inside the housing 1 with a base plate 21 is closed.
  • the ventilation pipe 2 has on its, facing away from the sheet metal disc 21, outside the Ventilation box lying side a connector that is connected to a supply air source that is not here is shown.
  • FIG. 1 Another embodiment of the arrangement of the ventilation tube 2 in housing 1 with horizontal ventilation pipe axis is exemplary on the right side of the housing 1 shown.
  • the ventilation pipe 2 a control valve 22, the outer diameter of which is somewhat smaller is than that of the perforated plate cylinder of the ventilation pipe 2 and the two bearing journals 26 in the perforated plate cylinder a horizontal axis is pivotally mounted.
  • the control valve 22 also consists of perforated sheet metal and is by means of a lever 23 adjustable in position.
  • Fig. 3 is one of the two journals of the control valve 22 shown in an enlarged view.
  • the control flap 22 On the outer circumference the control flap 22 is a U-shaped angle 25 attached, in the legs of holes for passage of the Bearing pin 26 are introduced.
  • the bearing pin 26 is inserted in the holes at an angle of 25 and in one of the openings in the perforated plate cylinder of the ventilation pipe 3.
  • a Coil spring 24 is the bearing pin at an angle 25 secured.
  • the spring 24 is supported on one of them Ends on one of the legs of the angle 25 and engages with the other end in an inserted in the journal 26 Groove one.
  • the Control flap 22 can be removed by the bearing pin 26th is pushed back against the spring force of the spring 24.
  • the ventilation box according to the invention is part of a Ventilation ceiling, can be in accordance with the requirements its size can be varied and one or more Have ventilation pipes 2.
  • the ventilation pipes 2 can either with a vertical axis, as shown on the left in FIG. 1, or with a horizontal axis, as in Fig. 1 on the right shown, to be installed. Have different attempts show that the effect is essentially the same and the Installation position of the ventilation pipes 2 therefore only from the Space is dependent. Is over the ventilation ceiling, in which the ventilation box according to the invention is integrated, there is enough space, so is an installation position of the ventilation pipe 2 with a vertical axis. However, the spatial conditions are above the top of the ventilation box is cramped, so an installation with horizontal axis of the ventilation pipe 2 is recommended.
  • honeycomb insert 11 and perforated plate 10 provides one very uniform air outlet over the entire perforated sheet surface.
  • this combination is therefore is so advantageous because of the perforated Ventilation pipe 2 with closed bottom 21 the supply air is evenly distributed inside the housing 1 so that a constant pressure prevails everywhere in the housing 1.
  • Honeycomb insert 11 in turn has a directional effect. Through the Openings in the honeycomb insert 11, the air from the inside of the housing 1 aligned vertically and flows in one uniform air curtain through the perforated plate 10 in the room to be ventilated.
