Description

Den foreliggende opfindelse angår et udluftningsaggregat til indsætning i en åbning og af den i krav 1’s indledning angivne art.BACKGROUND OF THE INVENTION The present invention relates to a vent assembly for insertion into an orifice and of the nature of claim 1.

Til at lede "brugt" luft ud af lokaler anvendes for det meste ventilationsgitre med parallelle, indstillelige lameller, idet lamellerne kan svinges enten enkeltvis eller samlet omkring langsgående akser. Når sådanne ventilationsgitre anvendes, skal der yderligere monteres reguleringsspjæld eller skydeventiler.· for at regulere strømningen i udluftningskanalen. Disse yderligere indretninger til at regulere strømningen medfører en kraftig forøgelse af den opstående luftstøj.For venting "used" air out of rooms, ventilation grids with parallel, adjustable slats are mostly used, the slats being pivoted either individually or assembled around longitudinal axes. When such ventilation grilles are used, additional control dampers or sliding valves must be fitted to regulate the flow in the vent duct. These additional devices for regulating the flow cause a significant increase in the rising air noise.

Selve udluftningsgitteret kan ikke anvendes til strømningsre-guleringen, da dette ville medføre en utilladelig kraftig støj. Endvidere tilsmudses lamellerne i de kendte udluftningsgitre meget hurtigt, og det er meget besværligt at rengøre dem ved hjælp af almindelige midler, som f.eks. støvsugere eller lignende .The vent grating itself cannot be used for the flow control, as this would cause an unacceptably loud noise. Furthermore, the slats in the known vent grilles are soiled very quickly and it is very troublesome to clean them by ordinary means, such as for example. vacuum cleaners or the like.

Fra tysk offentliggørelsesskrift nr. 20 06 928 kendes et udluftningsaggregat, hvor en meget begrænset mængderegulering ved omstilling af aggregatets ledevægge kan ske på en meget omstændelig måde ved drejning af en dobbeltskrue. Aggregatet må derfor have et indstilleligt slidsgitter til mængderegule-ring. Desuden er en retningsændring af den udstrømmende luft ikke mulig.German Patent Publication No. 20 06 928 discloses a vent assembly, in which a very limited amount control can be made in a very cumbersome manner by turning a double screw when adjusting the guide walls of the unit. The unit must therefore have an adjustable slot grating for volume control. In addition, a change of direction of the outflow air is not possible.

Også ved det aggregat, der kendes fra tysk offentliggørelsesskrift nr. 23 33 372, er mængderegulering ved omstilling af en lamel kun mulig i ringe grad. Ved dette aggregat er det dog muligt at retningsændre den udstrømmende luft ved at vippe lamellen. Imidlertid udsendes luften i et bredt strålebundt, som dels betinger en lille rækkevidde, dels medfører en kraftig støjudvikling.Also, by the assembly known from German publication specification No. 23 33 372, quantity adjustment by conversion of a slat is only possible to a small extent. With this unit, however, it is possible to change the direction of the flowing air by tilting the slat. However, the air is emitted in a broad beam bundle, which is partly conditional on a small range and partly causes a strong noise development.

Intet af de to ovennævnte kendte udluftningsaggregater er enkle at fremstille, og de er vanskelige at rengøre, især udefra.Neither of the above two known venting assemblies is easy to manufacture and difficult to clean, especially from the outside.

Formålet med opfindelsen er at anvise et udluftningsaggregat af den indledningsvis angivne art, som både gør det muligt at opnå en bekvem strømningsregulering uden kraftig støjudvikling og er let at rengøre udefra.The object of the invention is to provide a venting assembly of the kind stated at the outset, which both makes it possible to obtain a convenient flow control without strong noise development and is easy to clean from the outside.

Dette opnås ifølge opfindelsen ved den i krav 1 anviste udformning.This is achieved according to the invention in the embodiment of claim 1.

Ved hjælp af de tre lameller i udluftningsaggregatet ifølge opfindelsen er der dannet to bort fra hinanden i udløbsretningen forløbende kanaler med parallelle vægge, hvis tværsnit kan indstilles vilkårligt ved at forskyde ledefladerne. Ved at kanalerne forløber bort fra hinanden, optræder der kun en ubetydelig hvirveldannelse, og da luften føres gennem kanaler med parallelle vægge, formindskes støjudviklingen yderligere.By means of the three slats in the vent assembly according to the invention, two parallel walls extending parallel to the outlet direction are formed, the cross-sections of which can be arbitrarily adjusted by displacing the guide surfaces. By extending the channels away from each other, only insignificant vortex formation occurs, and as the air is passed through channels with parallel walls, the noise evolution is further reduced.

Selv ved en kraftig drøvling ved en vilkårli g formindskelse af kanaltværsnittet opstår der kun ringe støj. På den anden - 3 - 147627 side er det ved forskydning af lamellerne i indbyrdes vinkelrette retninger muligt at indstille kanalerne til vilkårligt store tværsnit, så at gennemstrømningen kan reguleres inden for vide grænser. Yed enhver kanalbredde er det særdeles enkelt at foretage rengøring udefra.Even in the case of a severe turbulence at any reduction in the duct cross section, little noise is produced. On the other hand - by displacing the slats in mutually perpendicular directions, it is possible to set the channels to any large cross-section so that the flow can be controlled within wide limits. For any duct width, cleaning from the outside is extremely easy.

Det foretrækkes, at aggregatet udformes som anvist i krav 2. Herved sikres det på en enkel måde, at luften kun strømmer gennem de med parallelle vægge udformede udløbskanaler. Samtidig opnås, at aggregatets yderflade udviser indbyrdes parallelt forløbende flader på de enkelte lameller, og når kanalerne er indstillet på middelstor bredde, vil disse flader endda flugte med hinanden.It is preferred that the assembly is designed as described in claim 2. This ensures in a simple way that the air flows only through the outlet ducts formed with parallel walls. At the same time, it is achieved that the outer surface of the assembly exhibits mutually extending surfaces on the individual slats, and when the channels are set to medium width, these surfaces will even align with each other.

Yderligere kan aggregatet ifølge opfindelsen være udformet som anvist i krav 3 , så at samtlige lameller vender lommeformede fordybninger imod luftstrømmen, hvad der medfører en vis opstuvning og dermed en god strømningsregulering uden større støjudvikling.Further, the assembly according to the invention can be designed as claimed in claim 3, so that all slats face pocket-shaped recesses against the air flow, which results in a certain buoyancy and thus a good flow regulation without major noise development.

Opfindelsen skal i det følgende forklares nærmere under henvisning til tegningen, hvor fig. 1 viser et snit gennem et aggregat ifølge opfindelsen langs linien I-I i fig. 3, idet aggregatet er vist med bredt indstillede kanaler, fig. 2 et til fig. 1 svarende snit, men med snævert indstillede kanaler, og fig. 3 aggregatet set udefra.The invention will now be explained in more detail with reference to the drawing, in which 1 shows a section through an assembly according to the invention along the line I-I in FIG. 3, the assembly being shown with broadly tuned channels; FIG. 2 is a view of FIG. 1, but with narrowly tuned channels, and FIG. 3 from the outside.

Mellem to parallelt over for hinanden beliggende bæreplader 10 og 12 er der lejret tre i længderetningen forløbende lameller, nemlig en midterlamel 14 og to yderlameller 16 og 18, parallelt med hinanden. Hver af de to yderlameller 16 og 18 omfatter en skråt i forhold til udløbsretningen 20 forløbende, plan ledeflade 22 henholdsvis 24. Midterlamellen 14 har to plane ledeflader 26 og 28, som forløber bort fra hinanden i udløbsretningen 20, idet ledefladen 26 forløber parallelt med ledefladen 22, og ledefladen 28 parallelt med ledefladen 24, på den pågældende yderlamel 16 henholdsvis 18. Herved er der dannet to udløbskanaler 30 og 32 med parallelle vægge.Between two supporting plates 10 and 12 located parallel to one another, three longitudinally extending slats are mounted, namely a center slat 14 and two outer slats 16 and 18, parallel to each other. Each of the two outer slats 16 and 18 comprises an inclined planar face 22 extending relative to the outlet direction 20, respectively 24. The central slat 14 has two planar guide faces 26 and 28 which extend apart in the outlet direction 20, the guide surface 26 extending parallel to the guide surface. 22, and the guide surface 28 in parallel with the guide surface 24, on the respective outer lamina 16 and 18. Thereby, two outlet channels 30 and 32 with parallel walls are formed.

Ydermere omfatter hver lamel en på tværs af udløbsretningen 20 forløbende tværflade 34,36 henholdsvis 38, som er tilsluttet de pågældende ledeflader. Tværfladerne 34 henholdsvis 38 på de to yderlameller er ved yderkanten ombukket til dannelse af smalle kantflanger 40 henholdsvis 42. Herved danner samtlige lameller imod udløbsretningen vendende lommer 44, 46 henholdsvis 48.Furthermore, each slat comprises a transverse surface 34,36 and 38 extending transversely of the outlet direction 20, respectively, which are connected to the respective guide surfaces. The transverse surfaces 34 and 38, respectively, of the two outer slats are folded at the outer edge to form narrow edge flanges 40 and 42, respectively. All the slats form pockets 44, 46 and 48 respectively facing the outlet direction.

I hver bæreplade 10 og 12 er der udformet to parallelt med udløbsretningen 20 forløbende slidser 50 og to vinkelret herpå forløbende slidser 52. Hver ledeflade er fastgjort til en bolt 54 henholdsvis 56, som hver er ført udad gennem en af slidserne 52 henholdsvis 54. Den udragende del af hver bolt er udformet med et ikke vist gevind, hvorpå der er indskruet en møtrik 58 henholdsvis 60. Ved at løsne møtrikkerne 58 henholdsvis 60 kan den tilhørende bolt let forskydes langs med slidserne 50 henholdsvis 52, så at den pågældende lamel kan indstilles efter ønske. På denne måde kan f.eks. midterlamellen 14 anbringes i den mest yderligere stilling som vist i fig. 1 eller i den i fig. 2 viste mellemstilling. Hver af de to yderlameller kan fra den i fig. 1 og 2 viste inderste stilling føres ud til yderstillinger, hvori boltene 54 befinder sig i de yderste ender af slidserne 52. Lamellerne kan også efter ønske indstilles i en hvilken som helst mellemstilling, så at tværsnittet af kanalerne 30 og 32 kan indstilles efter ønske.In each support plate 10 and 12, two slots 50 extending in parallel with the outlet direction 20 and two perpendicular slots 52 extending perpendicular thereto are formed. Each guide surface is fixed to a bolt 54 and 56, respectively, which are extended outwardly through one of the slots 52 and 54 respectively. protruding portion of each bolt is formed with a thread not shown, on which is screwed a nut 58 and 60, respectively. By loosening the nuts 58 and 60, respectively, the associated bolt can be easily displaced along the slots 50 and 52, respectively, so that the slat in question can be adjusted. by request. In this way, e.g. the center slat 14 is placed in the most additional position as shown in FIG. 1 or in the embodiment of FIG. 2. Each of the two outer slats can be viewed from the one shown in FIG. 1 and 2 are extended to outer positions in which the bolts 54 are located at the outer ends of the slots 52. The slats can also be adjusted in any intermediate position as desired, so that the cross-section of the channels 30 and 32 can be adjusted as desired.

Ved den i fig. 2 viste indstilling ligger tværfladerne 34, 36 og 38 nærmest flugtende med hinanden, hvad der svarer til et middelstort kanaltværsnit.In the embodiment shown in FIG. 2, the transverse surfaces 34, 36 and 38 are almost flush with each other, which corresponds to a medium channel cross-section.
