o 1 DK 166843 B1o 1 DK 166843 B1
Opfindelsen angår et luftindblæsningsgitter til indbygning i en udsparing i en luftkanal i et klimaanlæg og med flere horisontale, indbyrdes parallelle, luftledende lameller, der er svingbart lejrede i en rektangulær ramme og et fælles 5 til luftindblæsningsgitteret fastgjort svingdrev til temperaturafhængig indstilling af lamellernes hældning, idet der ved enden af hver lamel er fastgjort et tandhjul, hvilket tandhjul er i indgreb med en tandstangslignende, fortandet drivplade, som ved hjælp af en lineær føring er frem- og tilbage-10 forskydelig mellem en af rammens vægge og en dermed parallel føringsplade, og hvis længde sammen med dens forskydningslængde er mindre end afstanden mellem de parallelt med lamellerne forløbende rammevægge.The invention relates to an air supply grille for installation in a recess in an air duct in an air conditioner and with several horizontal, mutually parallel, air-conducting lamellae which are pivotally mounted in a rectangular frame and a common 5 for the air supply grille to attach pivot drives for temperature-dependent adjustment of lamellae. attached to the end of each slat is a gear, which gear engages a rack-like toothed drive plate which is displaceable back and forth by means of a linear guide between one of the walls of the frame and a guide plate parallel thereto, and whose length together with its displacement length is less than the distance between the frame walls extending parallel to the slats.
Et luftindblæsningsgitter af denne art kendes fra 15 DE-B 3204613. Drivorganet er en indstillingsmotor med reduktionsgear, og forskydningen af drivpladens sker ved, at en excentrikstift griber ind i en slids i pladen. Til temperaturafhængig indstilling af luftledelamellernes hældning kræves en elektrisk styring med en temperaturføler.An air supply grille of this type is known from 15 DE-B 3204613. The drive means is an adjusting motor with reduction gear, and the displacement of the drive plate takes place by an eccentric pin engaging in a slot in the plate. For temperature-dependent adjustment of the inclination of the air guide vanes, an electrical control with a temperature sensor is required.
20 Formålet med opfindelsen er at tilvejebringe et luft indblæsningsgitter af den omhandlede art, som ved simpel, pladsbesparende og robust udformning af drivmekanismen kan fremstilles meget billigt som et masseprodukt og muliggør automatisk indstilling af luftledelamellernes skråstilling i direkte af-25 hængighed af temperaturen af den gennemstrømmende luft ved tilstrækkelig vinkelændring. Dette er opnået ved at udforme luftindblæsningsgitteret som angivet i krav 1's kendetegnende del.The object of the invention is to provide an air supply grille of the type in question which, by simple, space-saving and robust design of the drive mechanism, can be manufactured very cheaply as a mass product and enables automatic adjustment of the inclination of the air guide vanes directly depending on the temperature of the flow-through. air at sufficient angular change. This is achieved by designing the air supply grille as stated in the characterizing part of claim 1.
Cylinder-stempelenheden og den i modsat retning af denne 30 virkende fjeder kan på meget pladsbesparende måde anbringes på luftindblæsningsgitterets ramme, således at montagen af gitteret i vægudsparingen i en luftkanal ikke hindres, og således at luftens strømningsvej ikke forstyrres. Beholderen, der indeholder det termisk udvidelige drivmedium, kan som et 35 o 2 DK 166843 B1 forholdsvis langt rør strække sig over gitterets gennemstrømningstværsnit, således at den har en stor varmeoverførings-flade og tils traskkel igt opbevar ing s vo lumen til ved tanperaturæn-dringer at forskyde drivorganets stempel over en længde, som 5 svarer til en tilstrækkelig vinkelændring af luftledelamel-lernes stilling.The cylinder-piston unit and the spring acting in the opposite direction to this can be placed on the frame of the air supply grid in a very space-saving manner, so that the mounting of the grid in the wall recess in an air duct is not hindered and so that the air flow path is not disturbed. The container containing the thermally expandable drive medium can, as a relatively long tube, extend over the flow cross-section of the grid, so that it has a large heat transfer surface and, for intrusive storage volume, changes during temperature changes. to displace the piston of the drive means over a length which corresponds to a sufficient angular change of the position of the air guide vanes.
I en fordelagtig udførelsesform for opfindelsen er cylinder-stempelenheden kombineret med et skrueelement, som muliggør indstilling af den til en given temperatur svarende 10 skråstilling af de luftledende lameller.In an advantageous embodiment of the invention, the cylinder-piston unit is combined with a screw element, which makes it possible to adjust the inclination of the air-conducting lamellae corresponding to a given temperature.
Opfindelsen angår også et indstillingsværktøj til betjening af det nævnte skrueelement, hvilket indstillingsværktøj kan være udført som et kombineret værktøj, som desuden kan benyttes til manuel indstilling af lameller, der ikke er 15 forbundet med det nævnte drivorgan, i deres luftledende retning.The invention also relates to an adjusting tool for operating said screw element, which adjusting tool can be designed as a combined tool, which can furthermore be used for manual adjustment of slats not connected to said drive means in their air-conducting direction.

Luftindblæsningsgitre 1 svarende til de i fig. 1-4 viste er kendt og findes i talrige rum såsom fabrikationshaller, restauranter og på lignende steder. De udgør en del af et klimaanlæg, idet de er monteret efter hinanden, som 15 vist i fig. 1, i vægudsparinger 2 i en fra et centralt luftopvarmnings- og eller luftafkølingsanlæg kommende luftkanal 3. Luftindblæsningsgitrene giver ved hjælp af deres talrige vertikale og horisontale luftledende lameller 3, 4 den i retning af pilene 6 fra luftkanalen 3 udstrømmende luft den Øn-20 skede retning ved indstrømningen i rummet, hvis klima skal styres. En fortrinsvis på bagsiden af luftindblæsningsgitte-ret anbragt luftfordelingskasse 7 strækker sig voksende i luftkanalens længderetning ind i denne, således at luften fordeles ensartet over luftindblæsningsgitterets 1 åbnings-25 tværsnit.Air supply grilles 1 corresponding to those in fig. 1-4 are known and are found in numerous rooms such as manufacturing halls, restaurants and similar places. They form part of an air conditioner, being mounted one after the other, as shown in fig. 1, in wall recesses 2 in an air duct coming from a central air heating and / or cooling system 3. The air supply grilles, by means of their numerous vertical and horizontal air-conducting lamellae 3, 4, give the air flowing out in the direction of the arrows 6 from the air duct 3 the desired stage. direction of the inflow into space whose climate is to be controlled. An air distribution box 7, preferably arranged on the rear side of the air supply grid, extends growing in the longitudinal direction of the air duct into it, so that the air is uniformly distributed over the opening cross-section of the air supply grid 1.
Den ønskede strømningsretning af den fra luftindblæs- ningsgitteret udstrømmende luft eller den optimale strømnings- retning er hvad angår dens i et vertikalt til luftkanalen 3 forløbende plan målte hældningsvinkel afhængig af temperatur- 30 differensen mellem den udstrømmende luft og rumlufttemperaturen.The desired flow direction of the air flowing out of the air supply grid or the optimum flow direction is with respect to its inclination angle measured in a plane extending vertically to the air duct 3 depending on the temperature difference between the outflowing air and the room air temperature.
Hensigtsmæssigt udblæses kold luft opad i rummet udstrømmende fra en over hovedhøjde forløbende luftkanal 3, således at den kolde luft får en stor kastevidde uden at kunne blæse direkte ned på personer. Varmluft til hurtig og energibesparende op-35 o 4 DK 166843 B1 varmning af et rum indblæses derimod så stejlt som muligt nedad mod gulvet i rummet, hvorfra den efter at have afgivet en del af sin varme stiger langsommere opad. Fig. 5 og 6 viser eksempler på udstrømningsretningerne ved bestemte temperaturer, 5 således som de automatisk indstilles ved hjælp af luftindblæs-ningsgitteret ifølge opfindelsen, idet de horisontalt rettede lameller drejer over en vinkel på maksimalt ca. 100°. I de viste eksempler er anvendt en sådan forud fastsat indstilling, at udstrømningen sker i horisontal retning ved en temperatur 10 på 20°C. Som nærmere beskrevet i det følgende kan den forud givne indstilling udføres ved drivmekanismen for luftindblæs-ningsgitteret ifølge opfindelsen.Suitably, cold air is blown upwards into the space exiting from an air duct 3 extending above head height, so that the cold air has a large throwing width without being able to blow directly down on persons. Hot air for fast and energy-saving heating of a room, on the other hand, is blown in as steeply as possible downwards towards the floor in the room, from where it rises more slowly upwards after giving off part of its heat. FIG. 5 and 6 show examples of the outflow directions at certain temperatures, 5 as they are automatically adjusted by means of the air supply grille according to the invention, the horizontally directed slats rotating through an angle of at most approx. 100 °. In the examples shown, such a predetermined setting is used that the outflow takes place in the horizontal direction at a temperature 10 of 20 ° C. As described in more detail below, the preset setting can be performed by the drive mechanism of the air supply grille according to the invention.
Drivmekanismen 8, der bevirker den automatiske indstilling af skråstillingen af de horisontale lameller 5 er næsten 15 anbragt i plan med en af de korte vægge 9 i luftindblæsnings-gitterets ramme 10, således at den ikke væsentligt forøger rammens yderdimensioner og ikke hindrer montagen af luftind-blæsningsgitteret i en udsparing 2 i luftkanalen 3.The drive mechanism 8, which causes the automatic adjustment of the inclination of the horizontal slats 5, is arranged almost flush with one of the short walls 9 in the frame 10 of the air supply grid, so that it does not significantly increase the outer dimensions of the frame and does not prevent the mounting of air the blowing grid in a recess 2 in the air duct 3.
Drivmekanismen 8 har en stempel-cylinderenhed 11, hvis 20 cylinder 12 er forbundet med en rørformet beholder 13. Denne i øvrigt tæt lukkede beholder er fyldt med et medium som f.eks. "Freon", der udvider sig forholdsvis kraftigt ved opvarmning, og beholderen strækker sig i bueform over åbningsarealet i luftindblæsningsgitteret l's ramme 10. Den fra luftindblæs-25 ningsgitteret udstrømmende luft omstrømmer således den rørformede beholder, således at det indesluttede medium udvider sig ved temperaturforøgelse og strømmer ind i cylinderen 12, hvor den forskyder det i cylinderen bevægelige stempel og dettes stempelstang 14. Bevægelsen af stempelstangen, som sker on mod virkningen af en parallelt med cylinder-stempelenheden 11 anbragt trækfjeder 15, overføres til en drivplade 16, idet en fra denne i L-form fremspringende arm 17 griber ind i en slids i den yderste ende af stempelstangen 14. Enden af stempelstangen griber desuden ind i en til denne tilpasset ud-35 5 DK 166843 B1 o sparing 19. Trækfjederen 17 er ved sin ene ende fastgjort til den yderste ende af drivpladens arm 17 og ved sin anden ende til en konsol 20 på hvilken også drivmekanismens cylinder 12 er anbragt. Trækfjederen 15 holder således drivpladens arm 5 17 mod stempelstangen og bevæger drivpladen tilbage, når tem peraturen af den udstrømmende luft synker.The drive mechanism 8 has a piston-cylinder unit 11, the cylinder 12 of which is connected to a tubular container 13. This otherwise tightly closed container is filled with a medium such as e.g. "Freon", which expands relatively sharply on heating, and the container extends in an arcuate shape over the opening area of the frame 10 of the air supply grid 1. The air flowing out of the air supply grid thus flows around the tubular container, so that the enclosed medium expands and increases in temperature. flows into the cylinder 12, where it displaces the piston movable in the cylinder and its piston rod 14. The movement of the piston rod, which takes place against the action of a tension spring 15 arranged parallel to the cylinder-piston unit 11, is transmitted to a drive plate 16, a L-shaped projecting arm 17 engages in a slot in the outer end of the piston rod 14. The end of the piston rod also engages in a recess adapted thereto 35 5 DK 166843 B1 o recess 19. The tension spring 17 is fastened at one end to the outermost end of the drive plate arm 17 and at its other end to a bracket 20 on which also the cylinder 12 of the drive mechanism is arranged . The tension spring 15 thus holds the arm 5 17 of the drive plate against the piston rod and moves the drive plate back when the temperature of the outflowing air drops.
Drivpladen 16 står i drivforbindelse med de horisontale lameller 5, der skal indstilles afhængigt af temperaturen. Til dette formål er der om hver lamels 5 svingningsakse 22 10 fastgjort et tandhjul 23, og på drivpladen 16 er udformet en tandstanglignende fortanding 24, som er i indgreb med tandhjulene 23. Retliniet føring af drivpladens bevægelse opnås ved hjælp af mindst to føringsringe 26, 27, der griber ind i langs en fælles linie forløbende retliniede slidser 28, 15 29 i drivpladen. I sideretningen er drivpladens løftebevægel se styret mellem rammens væg 9 og en parallelt med denne væg fastgjort føringsplade 30. Føringsringene 26, 27 danner herved samtidig afstandsringe for føringspladen. De er hver fastgjort til rammen 6 med en skrue 32. Desuden støtter en afbøjet ende 20 33 af føringspladen mod rammens væg 9 og holder pladen i af stand fra denne.The drive plate 16 is in drive connection with the horizontal slats 5 to be adjusted depending on the temperature. For this purpose, a pivot axis 22 10 is fixed about each pivot axis 22 10, and a gear rack-like toothing 24 is formed on the drive plate 16, which tooth engages with the gears 23. The rectilinear guidance of the movement of the drive plate is achieved by means of at least two guide rings 26, 27, which engages in rectilinear slits 28, 15 29 extending along a common line in the drive plate. In the lateral direction, the lifting movement of the drive plate is controlled between the wall 9 of the frame and a guide plate 30 fixed in parallel with this wall. The guide rings 26, 27 thereby simultaneously form spacer rings for the guide plate. They are each fixed to the frame 6 with a screw 32. In addition, a deflected end 20 33 of the guide plate supports against the wall 9 of the frame and keeps the plate away from it.
I den viste foretrukne udførelsesform for luftind-blæsningsgitteret 1 er en navdel 35 på tandhjulene 23 lejrede i en boring i føringspladen 30, som støtter akselen 22 på 25 den pågældende lamel 5, og føringspladen 30 er fastgjort til indersiden af rammens væg 9. Tandhjulene 23 befinder sig altså i samme spalte 36 som drivpladen og er ligeledes styrede i sideretningen i denne spalte. Drivmekanismen er følgelig understøttet inde i luftindblæsningsgitterets ramme 10.In the preferred embodiment of the air supply grid 1 shown, a hub portion 35 of the gears 23 is mounted in a bore in the guide plate 30 which supports the shaft 22 of the respective slat 5 and the guide plate 30 is attached to the inside of the frame wall 9. The gears 23 is thus located in the same slot 36 as the drive plate and is also guided in the lateral direction in this slot. The drive mechanism is consequently supported inside the frame 10 of the air supply grille.
30 Konsollen 20, som bærer cylinderen 12 i stempel-cy- linderenheden 11 omslutter denne skålformet udvendigt, som det ses i fig. 13, således at drivmekanismen er beskyttet mod beskadigelse under transport eller under montagen af luftindblæsningsgitteret.The bracket 20, which carries the cylinder 12 in the piston-cylinder unit 11, encloses it cup-shaped on the outside, as can be seen in fig. 13, so that the drive mechanism is protected against damage during transport or during the assembly of the air supply grille.
35 6 DK 166843 B1 o I bunden 37 af den skålformede konsol 20 er fastgjort en gevindbøsning 34, i hvilken en gevindtap 40 på en kappeformet cylinderfatning 41 griber ind, således at denne ved drejning om sin akse kan skrues op og ned for indstilling 5 af cylinder-stempelenheden 11 i aksial retning og dermed indstilling af den til en bestemt temperatur af den gennem luft-indblæsningsgitteret strømmende luft svarende skråstilling af de horisontale, luftledende lameller. Drejningen af cylinderfatningen 41 eller indstillingen af denne sker ved hjælp af 10 et stavformet indstillingsværktøj 43, som ved sin ene tilspidsende ende 44 har en tandlignende udvendig fortanding 45, som med hånden kan bringes i indgreb med en udvendig fortanding 46 på den kappeformede cylinderfatning 41. Forskydning af det stavformede indstillingsværktøj i dets længderetning, 15 medens det trykkes ind mod fortandingen 46, bevirker den nævnte indstilling. Det stavformede indstillingsværktøj kan herunder indskydes mellem de indbyrdes krydsende lameller 4 og 5 i luftindblæsningsgitteret fra dettes forside og ind til cylinderfatningen 41. Til indstilling af den lodrette, i den 20 viste udførelsesform yderste række lameller 4, som ikke har forbindelse med et drivorgan, er den modsat fortandingen liggende ende 48 af indstillingsværktøjet udformet med en slids 49, med hvilken lamellerne 4 kan gribes énkeltvis og drejes om deres akse ind i en anden stilling.35 6 DK 166843 B1 o In the bottom 37 of the cup-shaped bracket 20 a threaded sleeve 34 is fixed, in which a threaded pin 40 on a casing-shaped cylinder socket 41 engages, so that it can be screwed up and down by turning its axis for setting 5 of the cylinder-piston unit 11 in the axial direction and thus adjusting it to a certain temperature of the inclination of the air flowing through the air supply grid of the horizontal, air-conducting lamellae. The cylinder socket 41 is rotated or adjusted by means of a rod-shaped adjusting tool 43, which at its one tapered end 44 has a tooth-like external toothing 45, which can be manually engaged with an external toothing 46 on the casing-shaped cylinder socket 41. Displacement of the rod-shaped adjusting tool in its longitudinal direction, while being pressed against the toothing 46, causes said adjustment. The rod-shaped adjusting tool can be inserted between the mutually intersecting slats 4 and 5 in the air supply grid from its front and into the cylinder socket 41. To adjust the vertical, in the embodiment shown, the outermost row of slats 4, which are not connected to a drive means, are the opposite toothing end 48 of the adjusting tool formed with a slot 49, with which the slats 4 can be gripped individually and rotated about their axis into another position.
