Definitions

  • the invention relates to a separator for a device for ventilating rooms with a humid and / or rich atmosphere, in particular in the form of a cassette-shaped element for a false ceiling or for a grease trap, with open, arc-shaped, parallel backdrops being provided in cross section and in each case two groups of such scenes with the open sides facing each other and laterally offset from one another in such a way that the open sides partially overlap, in particular reach behind at such a distance that a chamber which widens the flow cross section is formed between the narrowing of the edges, the chamber being arcuate in cross section Scenes have end walls at their ends.
  • Such a separator is known from DE-C-27 18 611.
  • the good separation of moisture and fat from an air directed through such cassettes and scenes is advantageous.
  • Soft solder must be pre-etched with strong caustic agents so that the solder holds onto the material.
  • yellow chrome-nickel steel can corrode after such an etching process, which is particularly prohibitive in the kitchen area.
  • the surprising solution to this problem is that the in the use position with its opening facing upward at its ends are deformed in such a way that a wall part consisting of one piece with the backdrop stands out from the lowest point of the backdrop over only part of its height and also consists of one piece along its edge area with the backdrop.
  • the wall part connected in one piece to the backdrop is designed as a tongue-shaped projection protruding from a sheet-metal strip which later forms the backdrop, and if the cross-sectionally arc-shaped or circular-arc-shaped backdrop in the area of this tongue-shaped projection is deep-drawn in such a way that this projection in the use position has its predetermined cross-sectional height forms an integral closure of the backdrop.
  • the shaping of the wall part is not done by a more or less imprecise and unsightly impression of the end face of the individual backdrop, but this is deep-drawn with its arch shape and the wall part at least in the front area. This makes it possible for the wall piece to be flat.
  • the upper edge regions of the curved link can be provided with projections which protrude from the end face and which, in the use position, have corresponding cross-sectional slots on the end wall. Both these projections and the flange of the wall part are thus available as retaining tongues for insertion into corresponding slots in the end wall, where they can then be bent over and thus fixed.
  • the flange located on the wall part and the projections located on the edges of the link can have an approximately identical axial extension and, in the use position - as already mentioned - the slots corresponding to their size push through the end wall and be bendable relative to the end wall.
  • the height of the one-piece end wall part can be smaller than the radius of curvature of the backdrop and, starting from the deepest point of the backdrop - in the position of use - can be, for example, about 3 mm to 8 mm or 10 mm, in particular about 5 to 6 mm.
  • a lower height of this wall part is easier to form and deep-draw, while a higher height provides more security against overflow.
  • this height is also limited by the fact that the backdrop, which is open at the bottom, should be able to partially engage in the backdrop, which is open at the top, and still requires some distance from the wall part.
  • transition from the link wall to the closing wall part or wall piece and / or the transition from the closing wall part to the holding flange can be rounded, which accommodates the deformation of the sheet forming the setting.
  • the tongue-shaped projection merges with radii into the end face of this sheet-metal strip, so that the deep-drawing process in this area with simultaneous curvature of the backdrop, the wall part lying between a secant and an arcuate piece can be formed.
  • a separator designated as a whole by 1 has the shape of a cassette-shaped element in the exemplary embodiment according to FIG.
  • cross-section open, arc-shaped, parallel backdrops 2 and 3 are provided and two groups of such backdrops 2 and 3 with the open sides facing each other and laterally offset from each other so that the open sides partially engage behind each other so that in Not shown in detail, but known from the prior art between the narrowing of the edges 2a and 3a of these scenes 2 and 3 forms a chamber widening the flow cross section, in which moisture and fat can be separated from air passed through the separator 1.
  • these have cross-sectionally curved scenes 2 and 3 at their ends end walls 4, whereby the scenes 2 and 3 are fixed in their relative position to each other and connected to each other.
  • the wall part 5 which protrudes transversely to the course of the backdrop and is integrally connected to the backdrop 3 along its edge 6, is a tongue-like projection 8 protruding from a sheet metal strip 7 which later forms the backdrop 3 is formed, and that the cross-sectionally arcuate or circular arcuate backdrop 3 is deep-drawn in the area of this tongue-shaped projection 8 such that this projection 8 forms a one-piece closure over a predetermined cross-sectional height of the backdrop 3 in the use position. It can be seen in FIG.
  • the tongue-shaped projection 8 is so long and protrudes beyond the curved transition 9 so far that a flange 11 or sheet metal tab is exposed along the upper edge of the final wall part 5, which according to FIG Retaining tongue or flange 11 can serve and fits into a correspondingly shaped holding slot 12 of the end wall 4.
  • the height of the one-piece end wall part 5 is smaller than the radius of curvature of the link 3 and starting from the lowest point of the link 3, for example, about 3 mm to 8 mm, in particular about 5 is up to 6 mm.
  • the height of the one-piece end wall part 5 is smaller than the radius of curvature of the link 3 and starting from the lowest point of the link 3, for example, about 3 mm to 8 mm, in particular about 5 is up to 6 mm.
  • the wall part 5 closes the end of the arcuate section of the cross section of the cassette 3 in one piece, it results that the upper edge of the end wall part 5 extends horizontally in the position of use and accordingly forms a horizontal secant on the arcuate cross section of the backdrop 3 .
  • This edge or termination of the wall part 5 thus corresponds to a liquid level in the backdrop 3.
  • transitions from the backdrop wall to the final wall part 5 and / or the transition from the final wall part 5 to the retaining flange 11 are expediently rounded.
  • the separator 1 preferably in the form of a cassette, has parallel links 2 and 3, each with an arcuate cross section, which engage with one another with their edges 2a and 3a in such a way that a chamber which widens the flow cross section for the air passed through it is formed, in which the flow velocity is reduced and the flow is swirled so that fat and moisture can be separated and caught by the upwardly open arcuate backdrop 3.
  • This backdrop 3 is deformed at its ends such that a wall part 5 integrally connected to it protrudes from its deepest point over part of its height and is also integrally connected to the backdrop 3 along its edge 6, so that separated liquid and fat cannot run out of this backdrop.
