Description

Raumleuchte mit RaumluftfiltrierungRoom lamp with room air filtration
Die Erfindung betrifft eine Raumleuchte mit integrierter Raumluftfiltriervorrich- tung, welche ein gehäuseartiges Tragelement, ein daran befestigtes Luftansaugsystem mit einem die Raumleuchte vertikal durchgreifenden Zentralkanal für von einem eingebauten Ventilator mit einem Ventilatorgehäuse durchgeblasene Raumluft, wenigstens einen austauschbaren Filter und einen entfernba- ren Lampenschirm umfasst.The invention relates to a room lamp with integrated room air filtering device, which comprises a housing-like support element, an air intake system attached thereto with a central channel vertically penetrating the room lamp for room air blown through by a built-in fan with a fan housing, at least one exchangeable filter and a removable lampshade.
Die US,A 2790510 beschreibt, ausgehend von einem Stand der Technik mit separat in einem Raum angeordneten Luftfiltern und Beleuchtungskörpern, eine Lampe mit integriertem Luftfilter. Dabei wird eine Filtereinheit, welche auch einen elektrischen Motor, einen mit diesem angetriebenen Ventilator und Einzelleuchten umfasst, auf einen Lampensockel aufgeschraubt. Der Eintritt von belasteter Luft erfolgt grossflächig durch einen obenliegenden Filter, die Luft tritt unten gereinigt in den Raum aus.US, A 2790510 describes, starting from a prior art with air filters and lighting elements arranged separately in a room, a lamp with an integrated air filter. In this case, a filter unit, which also comprises an electric motor, a fan driven with this and individual lights, is screwed onto a lamp base. The entry of contaminated air takes place over a large area through an overhead filter, the air exits into the room after cleaning.
Nach dem vorerwähnten Grundprinzip wird gemass der NL,A 8800812 eine Filtriereinheit in eine hängende Raumleuchte eingebaut. Unterhalb der Filtriereinheit, innerhalb des auswechselbaren Lampenschirms, ist eine Einzelleuchte mit einem inneren Lampenschirm aufgehängt, welcher Luftdurch- trittsöffnungen aufweist. Die belastete Luft wird so mit Hilfe eines Ventilators über den ganzen Querschnitt des äusseren Lampenschirms angesaugt, tritt über einen Vorfilter in die Filtriereinheit und verlässt diese über einen Aktivkohlefilter nach oben, wo sie ausgeblasen wird.According to the above-mentioned basic principle, a filter unit is installed in a hanging room lamp in accordance with NL, A 8800812. A single lamp with an inner lampshade, which has air through openings, is suspended below the filter unit, inside the replaceable lampshade. The contaminated air is sucked in with the help of a fan over the entire cross-section of the outer lampshade, enters the filter unit via a pre-filter and leaves the filter unit upwards, where it is blown out.
Die DE,U 9104400 offenbart die Reinigung von belasteter Raumluft in Kombi- nation mit einer Leuchtstoffröhre mit luftdichtem Lampenschirm. Die belasteteDE, U 9104400 discloses the cleaning of polluted room air in combination with a fluorescent tube with an airtight lampshade. The burdened
Raumluft wird stirnseitig über einen vollflächig angeordneten Staub- und/oder Fettfilter angesaugt, und tritt am andern Ende grossflächig über einen Aktivkohlefilter aus.Room air is exposed on the front side via a dust and / or surface covering the entire surface Grease filter sucked in and exits at the other end over a large area through an activated carbon filter.
Obwohl Raumleuchten mit integrierter Raumluftfiltrierung seit mehr als vierzig Jahren bekannt sind, werden noch heute Raumlüftungen zwecks Luftreinigung bzw. Luftaustausch, besonders in Gastronomiebetrieben, weitgehend separat mit Ventilatoren oder mit meist unter der Decke installierten Abluftkanälen direkt ins Freie bewerkstelligt. Im privaten Bereich wird durch das Öffnen von Fenstern Abhilfe geschaffen. Beide Massnahmen sind aus ökologischer Sicht wenig sinnvoll. Ausserdem können unerwünschte Durchzugserscheinungen auftreten und somit die Gesundheit beeinträchtigen.Although room lights with integrated room air filtration have been known for more than forty years, room ventilation for air purification or air exchange, especially in catering establishments, is still largely carried out separately with fans or with exhaust air ducts mostly installed under the ceiling. Remedial measures are taken in the private area by opening windows. Both measures make little sense from an ecological perspective. In addition, unwanted drafts can occur and thus affect health.
Der Erfindung liegt die Aufgabe zugrunde, eine Raumleuchte mit integrierter Raumluftfiltriervorrichtung der eingangs beschriebenen Art zu schaffen, welche effizienter und räumlich gezielter eingesetzt werden kann.The invention has for its object to provide a room lamp with integrated room air filter device of the type described above, which can be used more efficiently and spatially targeted.
Die Aufgabe wird erfindungsgemäss dadurch gelöst, dass die Raumluftfiltriervorrichtung ein im unteren Bereich angeordnetes, doppelwandiges Einströmungsgehäuse mit einem Zwischenraum umfasst, welcher den periphereπ, ho- rizontalen Teil eines zum Zentralkanal führenden Ansaugschlitzes bildet. Spezielle und weiterbildende Ausführungsformen sind Gegenstand von abhängigen Patentansprüchen.The object is achieved according to the invention in that the room air filter device comprises a double-walled inflow housing arranged in the lower region with an intermediate space which forms the peripheral, horizontal part of an intake slot leading to the central channel. Special and further developments are the subject of dependent claims.
Die vorliegende Erfindung vereint die Eigenschaften einer an sich bekannten sogenannten Raumlunge und eines Lichtspenders in optimaler Weise. Die Verbindung von Raumbeleuchtung und Raumluftfiltrierung ermöglicht, die entstehenden Raumluftbelastungen, wie Tabakrauch, Speisegerüche, andere schlechte Gerüche und Dämpfe dort aufzunehmen, wo sie am meisten entstehen, nämlich direkt über den Tischen eines Lokals, sei es nun am Stammtisch, an der Bartheke oder zu Hause am Esstisch. Leicht auswechselbare Fett- und Aktivkohlefilter neutralisieren fettige Dämpfe und Nikotin grösstenteils. Die filtrierte Luft wird wieder in den Raum zurückgeführt. Passivrauchen wird dadurch stark reduziert. Textilien, Vorhänge im speziellen, sowie Einrichtungsgegenstände allgemein sind vermindert Raumbela- stungen ausgesetzt.The present invention optimally combines the properties of a so-called room lung known per se and a light donor. The combination of room lighting and room air filtration enables the resulting room air pollution, such as tobacco smoke, food smells, other bad smells and vapors to be absorbed where they are generated most, namely directly above the tables of a restaurant, be it at the regular table, at the bar counter or at At home at the dining table. Easily replaceable grease and activated carbon filters largely neutralize greasy vapors and nicotine. The filtered air is returned to the room. This significantly reduces passive smoking. Textiles, curtains in particular, and furnishings in general are less exposed to space.
Der Gestaltung der Leuchte, im wesentlichen derjenigen eines einfachen oder dekorativen Lampenschirms, sind bezüglich des Designs, der eingesetzten Materialien und deren Farben keine Grenzen gesetzt. Bei stets gleichbleibendem Grund- bzw. Tragelement lassen sich beliebige, auch eigens dafür entwickelte Schirmmodelle frei nach Wahl und leicht austauschbar aufsetzen.The design of the lamp, essentially that of a simple or decorative lampshade, has no limits with regard to the design, the materials used and their colors. With the basic or supporting element always remaining the same, any screen models, also specially developed for this purpose, can be freely placed and exchanged.
Der Zentralkanal durch die Raumleuchte wird im wesentlichen durch ein Ventilatorgehäuse mit einem stromab befestigten unteren Teil des Tragelementes einerseits sowie einem stromauf am Ventilatorgehäuse befestigten Einströmungsgehäuse gebildet, wobei die beiden dieses Gehäuse bildenden Einströmungsplatten den untersten Teil des axialsymmetrischen Zentralkanals bilden. Beide Einströmungsplatten haben weiter je einen rechtwinklig zur Längsachse des Zentralkanals peripher umlaufenden horizontalen Aussenflansch, welche in geringem Abstand von vorzugsweise 0,1 - 5 mm, insbesondere 0,5 - 2 mm, miteinander verschraubt sind. Die beiden Einströmungsplatten bilden einen mit dem Zentralkanal kommunizierenden Zwischenraum, welcher mit Blick auf seine Funktion Ansaugschlitz genannt wird. Dieser Schlitz erstreckt sich in der Regel horizontal bis in den Bereich des Zentralkanals, kann aber innenseitig des horizontalen peripheren Zwischenraums auch kegelstumpfförmig ansteigend ausgebildet sein. Zweckmässig ist der Ansaugschlitz wenigstens im Einmündungsbereich in den Zentralkanal erweitert ausgebildet.The central duct through the room lamp is essentially formed by a fan housing with a lower part of the support element fastened downstream and an inflow housing fastened upstream to the fan housing, the two inflow plates forming this housing forming the lowest part of the axially symmetrical central duct. Both inflow plates each have a horizontal outer flange which extends peripherally at right angles to the longitudinal axis of the central channel and which are screwed together at a small distance of preferably 0.1-5 mm, in particular 0.5-2 mm. The two inflow plates form an intermediate space which communicates with the central channel and which, in view of its function, is called an intake slot. This slot generally extends horizontally into the region of the central channel, but can also be designed in the shape of a truncated cone on the inside of the horizontal peripheral space. The suction slit is expediently designed to be expanded, at least in the region where it flows into the central channel.
Eine vorzugsweise zwischen den beiden Einströmungsplatten angeordnete Einsatzplatte mit durchgehenden radialen Strömungskanälen verbessert die Reinigungswirkung der Raumleuchte und dient als Distanzhalter. Die Effizienz der Raumleuchte kann bezüglich der Raumluftfiltrierung weiter gesteigert werden, indem ein speziell ausgebildeter Ventilator mit grösserer Saugkraft eingebaut wird. Dazu ist insbesondere ein elektromotorbetriebener Rohrventilator mit Laufrad geeignet. Ein in an sich bekannter Bauweise ausgebildetes Laufrad hat stehende Lamellen und eine zentrale Durchflussöffnung.A preferably arranged between the two inflow plates insert plate with continuous radial flow channels improves the cleaning effect of the room lamp and serves as a spacer. The efficiency of the room lamp can be further increased with regard to room air filtration by installing a specially trained fan with greater suction power. An electric motor-operated tubular fan with an impeller is particularly suitable for this. An impeller designed in a manner known per se has standing fins and a central flow opening.
Eine weitere vorzugsweise Ausführungsform der Erfindung lässt die Raumluft nicht oben, sondern bei verschlossener oberer Stirnseite des Zentralkanals seitlich durch geeignete Öffnungen austreten.Another preferred embodiment of the invention does not allow the room air to emerge laterally through suitable openings, but rather when the upper end face of the central duct is closed.
Die Vorteile der vorliegenden Erfindung können wie folgt zusammengefasst werden:The advantages of the present invention can be summarized as follows:
- Durch die Ausbildung eines peripher umlaufenden, horizontalen Eintrittsschlitzes für belastete Luft kann die Luftverbesserung gezielt durch Absaugen einer Luftschicht bewirkt werden. Zusammen mit den bevorzugten seitlichen Luftaustrittsöffnungen entsteht beispielsweise oberhalb eines Tisches eine die Luftqualität erhöhende Zirkulationsbewegung. - Durch das horizontale Ansaugen der verbrauchten Raumluft entsteht im- Through the formation of a peripheral circumferential, horizontal inlet slot for polluted air, the air improvement can be brought about by sucking off an air layer.

Eine in Fig. 1 dargestellte elektrische Raumleuchte 10 mit integrierter Raumluftfiltrierung ist im wesentlichen dreiteilig ausgebildet, sie besteht aus einem Tragelement 12, einem Luftansaugsystem 14 und einem Einströmuπgsgehäuse 16.An electrical room lamp 10 shown in FIG. 1 with integrated room air filtration is essentially of three parts, it consists of a support element 12, an air intake system 14 and an inflow housing 16.
Ein im wesentlichen als kreiszylinderförmiges Gehäuse 18 des Tragelementes 12 mit einem einschraubbaren Deckel 20, welcher eine coaxiale Hülse 22 für die Aufnahme eines elektrischen Versorgungskabels 24 aufweist, übernimmt die Tragfunktion für die ganze Raumleuchte 10, einen leicht auswechselbaren Lampenschirm 26 eingeschlossen.An essentially circular cylindrical housing 18 of the support element 12 with a screw-in cover 20, which has a coaxial sleeve 22 for receiving an electrical supply cable 24, assumes the carrying function for the entire room lamp 10, including an easily replaceable lampshade 26.
Das Gehäuse 18 und der Deckel 20 bilden eine Kammer 28, welche nach unten mit einem Einsatz 30 verschlossen ist. In dieser Kammer 28 sind einerseits die nicht dargestellten elektrischen Anschlüsse, Verteiler und Klemmen für Ein- zelleuchten 32 einerseits und das Luftansaugsystem 14 andererseits untergebracht. Weiter ist in dieser Kammer 28 ein stufenloser Regler 34 mit einem Ein- /Aus-Schalter, welcher von aussen mittels eines Drehknopfes 36 bedienbar ist, sowie ein Kondensator 38 angeordnet.The housing 18 and the cover 20 form a chamber 28 which is closed at the bottom with an insert 30. In this chamber 28, on the one hand, the electrical connections, distributors and terminals for individual lights 32, not shown, and the air intake system 14, on the other hand, are accommodated. Furthermore, a stepless controller 34 with an on / off switch, which can be operated from the outside by means of a rotary knob 36, and a capacitor 38 are arranged in this chamber 28.
An die geschlossene Kammer 28 anschliessend ist ein peripherer Versorgungskanal 40 für die Beleuchtungs- und Ventilatorkabel angeschlossen. Schliesslich umfasst das Tragelement 12 eine über das Gehäuse 18 gestülpte Haube 42, welche im unteren Bereich über wenigstens einen Teil des Um- fangs Austrittsöffnungen 44 aufweist, im vorliegenden Fall als Längsschlitze ausgebildet. Das Gehäuse 18 ist in diesem Bereich mindestens teilweise offen, Details werden in Fig. 3 angegeben. Der Einsatz 30 ist im Bereich der Austrittsöffnungen 44 für das gereinigte Gas aerodynamisch ausgebildet, im vorliegenden Fall konusförmig.A peripheral supply channel 40 for the lighting and fan cables is connected to the closed chamber 28. Finally, the support element 12 comprises a hood 42 which is slipped over the housing 18 and has outlet openings 44 in the lower region over at least part of the circumference, in the present case formed as longitudinal slots. The housing 18 is at least partially open in this area, details are given in FIG. 3. The insert 30 is aerodynamically formed in the region of the outlet openings 44 for the cleaned gas, in the present case conical.
Die zylindrische Haube 42 ist von oben aufgeschoben und liegt mit einem oberen, umlaufend rechtwinkligen Flansch 46 rundum auf dem Deckel 20 auf, zweckmässig dichtend. Durch Anheben der Haube 42 mit einem einfachen Handgriff wird ein auf einem umlaufenden Innensteg 48 des Gehäuses 18 aufliegender Aktivkohlefilter 47 zugänglich, was dessen einfache Auswechslung gewährleistet.The cylindrical hood 42 is pushed on from above and lies on the cover 20 with an upper, circumferentially rectangular flange 46 all around, expediently sealing. By lifting the hood 42 with a simple handle, an active carbon filter 47 resting on a circumferential inner web 48 of the housing 18 is accessible, which ensures its simple replacement.
Unterhalb der aufgesetzten, d.h. in normaler Lage befindlicher Haube 42, ist am zylindrischen Gehäuse 18 des Tragelementes 12 ein ringförmiger, nach oben abgewinkelter Aussensteg 49 angeordnet, welcher als Auflage für den auswechselbaren Lampenschirm 26 dient. Eigens dazu konzipierte Lampenschirme 26 lassen sich nach dem Entfernen des Eiπ-/Aus-Drehknopfes 36 problemlos über das ganze zylindrische Gehäuse 18 des Tragelementes 12 oder über die Haube 42 schieben und reinigen oder allenfalls auswechseln. Am unteren Ende des Tragelementes 12 ist das eigentliche Luftansaugesystem 14 in an sich bekannter Weise lösbar oder unlösbar befestigt, selbstverständlich luftdicht. Dieses Luftansaugesystem 14 besteht im wesentlichen aus einem Rohrventilator 50 mit einem Laufrad 52, welches in das Strömungsoptimierende Gehäuse eingebaut ist. Der Rohrventilator 50 ist ein wesentlicher Bestandteil eines Zentralkanals 54 mit der Längsachse L-L, welcher auch den unteren Teil des Tragelementes 12 sowie das nachstehend beschriebene Einströmungsgehäuse 16 umfasst. Im Zeπtralkanal 54 ist auch ein strömungstechnisch optimie- rendes Trennblech 56 anordnet.An annular, upwardly angled outer web 49, which serves as a support for the interchangeable lampshade 26, is arranged on the cylindrical housing 18 of the support element 12 below the hood 42 which is in the normal position. Specially designed lampshades 26 can be easily pushed over the entire cylindrical housing 18 of the support element 12 or over the hood 42 and cleaned or, if necessary, replaced after removing the on / off rotary knob 36. At the lower end of the support element 12, the actual air intake system 14 is detachably or non-releasably fastened in a manner known per se, of course airtight. This air intake system 14 essentially consists of a tube fan 50 with an impeller 52, which is installed in the flow-optimizing housing. The tubular fan 50 is an essential component of a central duct 54 with the longitudinal axis LL, which also includes the lower part of the support element 12 and the inflow housing 16 described below. In the central channel 54 there is also a fluidically optimized rendes divider 56 arranges.
Die Inbetriebnahme und Steuerung des Rohrventilators 50 erfolgt durch den stufenlosen Regler 34 mit dem dazugehörenden Kondensator 38 in der ge- schlossenen Kammer 28.The tube fan 50 is started up and controlled by the stepless controller 34 with the associated condenser 38 in the closed chamber 28.
Eine unterhalb des Rohrventilators 50 dichtend befestigte obere Einströmungsplatte 58 ist zwecks optimaler Luftansaugung bzw. Luftströmung teller- oder kegelstumpfförmig ausgebildet (Fig. 3,4). Ein peripher umlaufender, hori- zontaler Aussenflansch 59 der Einströmungsplatte 58 dient zugleich als Auflage für den Lampenschirm 26. Eine untere Einströmungsplatte 60 mit einem Aussenflansch 61 ist entsprechend ausgebildet und mit der oberen Einströmungsplatte 58 mittels Schrauben 78 so verbunden, dass im peripher umlaufenden, flanschförmig ausgebildeten Bereich 59,61 ein horizontaler doppel- wandiger Schlitz mit einem Zwischenraum 62 von etwa 1 mm entsteht, welcher mit dem Zentralkanal 54 kommuniziert. Durch diesen geringen Zwischenraum 62 entsteht eine verstärkte Saugwirkung, welche weiter vergrössert werden kann, indem hier nicht sichtbare Verengungen mit saugverstärkender Wirkung angelegt werden (Fig. 5). Aus den Ausführungen geht weiter hervor, dass die am Gehäuse des Rohrventilators 50 fest montierte obere Einströmungsplatte 58 auch als Träger für die untere Einströmungsplatte 60 dient.An upper inflow plate 58, which is sealingly fastened beneath the tubular fan 50, is designed in the shape of a plate or a truncated cone for the purpose of optimal air intake or air flow (FIGS. 3, 4). A peripheral circumferential, horizontal outer flange 59 of the inflow plate 58 also serves as a support for the lampshade 26. A lower inflow plate 60 with an outer flange 61 is designed accordingly and connected to the upper inflow plate 58 by means of screws 78 in such a way that in the peripherally circumferential, flange-shaped formed area 59, 61 there is a horizontal double-walled slot with a space 62 of approximately 1 mm, which communicates with the central channel 54. This small space 62 results in an increased suction effect, which can be increased further by creating constrictions that are not visible and which have a suction-enhancing effect (FIG. 5). It is further evident from the explanations that the upper inflow plate 58, which is fixedly mounted on the housing of the tubular fan 50, also serves as a carrier for the lower inflow plate 60.
Wie in Fig. 1 ersichtlich, sind in Vertiefungen 64 des unteren Einströmungsgehäuses 60 Leuchtkörperfassungen 66 mit eingeschraubten Einzelleuchten 32 installiert, beispielsweise Glühbirnen, fluoreszierende Röhren oder Niedervolt- Leuchter.As can be seen in FIG. 1, light fixtures 66 with screwed-in individual lights 32 are installed in recesses 64 of the lower inflow housing 60, for example light bulbs, fluorescent tubes or low-voltage lamps.
Die Öffnung für den Zentralkanal 54 mit umlaufendem, rechtwinklig nach unten abkragendem Rand 68 der unteren Einströmungsplatte 60 ist mit einem auf- schraubbaren Aufsatzdeckel 70 verschlossen. Die flache, tellerförmige Variante gemass Fig. 1 wird bevorzugt für mehrflammige Leuchten, also mit mehre- ren Einzelleuchten 32, verwendet. Dabei sind die Leuchtkörperfassungen 66 in kreiskegelstumpfförmigen Vertiefungen 64 der unteren Einströmungsplatte 60, je nach Anzahl, rundum angeordnet und installiert, vorzugsweise regelmässig.The opening for the central channel 54 with the peripheral edge 68 of the lower inflow plate 60 which projects downward at right angles is closed by a screw-on cover 70. The flat, plate-shaped variant according to FIG. 1 is preferred for multi-lamp lights, that is to say with multiple ren individual lights 32, used. The luminous element holders 66 are arranged and installed all around, preferably regularly, in circular truncated cone-shaped recesses 64 of the lower inflow plate 60, depending on the number.
Bezüglich der Längsachse L-L dient der von unten aufschraubbare runde und flache Aufsatzdeckel 70 nach dem Entfernen dem Zugriff für die Auswechslung bzw. Reinigung eines eingelegten Fettfilters 72. Weiter kann bei starker Dampf- und/oder Rauchentwicklung durch eine Drehung des Aufsatzdeckels 22 die Anzahl von Absaugöffnungen 74 erweitert oder verkleinert werden. Der Aufsatzdeckel 70 dient auch als Verschluss für die erwähnte Zugriffsöffnung.With respect to the longitudinal axis LL, the round and flat top cover 70 which can be screwed on from below serves for access after the removal for the replacement or cleaning of an inserted grease filter 72. In addition, in the event of strong steam and / or smoke development, the number of suction openings can be reduced by rotating the top cover 22 74 can be expanded or reduced. The top cover 70 also serves as a closure for the access opening mentioned.
Die in den Zwischenraum 19 und einen nach innen anschliessenden Ansaugschlitz 76, bei entsprechender Einstellung des Aufsatzdeckeis 70 auch in die Absaugöffnungen 74 strömende Raumluft ist mit gewellten Pfeilen und A be- zeichnet.The room air flowing into the intermediate space 19 and an intake slot 76 that adjoins the interior and, with a corresponding setting of the top cover 70, also into the suction openings 74 is denoted by wavy arrows and A.
Es ist offensichtlich, dass die Raumleuchte 10 gemass Fig. 1 nach einer nicht dargestellten Variante statt hängend als Ständerlampe ausgeführt werden kann. Das Tragelement 12 wird dann zum Stützelement, das Einströmungsge- häuse 16 ist oben angeordnet. Obwohl die Unterlagen im übrigen auf eine hängende Raumleuchte 10 ausgerichtet sind, wird die völlig äquivalente, stehende Raumleuchte vom Schutzumfang miterfasst. Der Lufteintritt erfolgt bei einer Ständerlampe im gleichen Höhenbereich wie bei einer hängenden Raumleuchte.It is obvious that the room lamp 10 according to FIG. 1 can be designed as a stand lamp instead of hanging according to a variant not shown. The support element 12 then becomes the support element, the inflow housing 16 is arranged at the top. Although the documents are otherwise directed to a hanging room lamp 10, the completely equivalent, standing room lamp is included in the scope of protection. The air intakes with a stand lamp in the same height range as with a hanging room lamp.
Der in Fig. 2 gezeigte Querschnitt durch den oberen Teil des Tragelementes 12 zeigt insbesondere die Anordnung des Kondensators 38, des stufenlosen Reglers 34 und dessen aussenbetätigten Drehknopfes 36. Weiter ist ersichtlich, dass bei entferntem Drehknopf 36 keine überstehenden Teil ausgebildet sind, was beim Auswechseln des Lampenschirms 26 (Fig. 1 ) vorteilhaft ist. Der Querschnitt durch den unteren Teil des Tragelementes 12 gemass Fig. 3 zeigt den Bereich mit Austrittsöffnungen 44 in der Haube 42. Links ist ein Aktivkohlefilter 47 angedeutet, welcher in der Arbeitsphase auf Innenstegen 48 aufliegt und bei angehobener oder bei abgenommener Haube 42 ein- bzw. auswechselbar ist. Die Haube 42 wird durch den peripheren Versorgungskanal 40 und Gehäuseteile 18 des Tragelementes 12 geführt.The cross section shown in FIG. 2 through the upper part of the support element 12 shows in particular the arrangement of the capacitor 38, the stepless regulator 34 and its externally operated rotary knob 36. Furthermore, it can be seen that when the rotary knob 36 is removed, no protruding parts are formed, which is the case when replacing it the lampshade 26 (FIG. 1) is advantageous. The cross section through the lower part of the support element 12 according to FIG. 3 shows the area with outlet openings 44 in the hood 42. An activated carbon filter 47 is indicated on the left, which rests on inner webs 48 in the working phase and which is in or out when the hood 42 is raised or removed is interchangeable. The hood 42 is guided through the peripheral supply channel 40 and housing parts 18 of the support element 12.
Die Ausführungsform gemass Fig. 4 entspricht im wesentlichen Fig. 1. Die Raumleuchte 10 umfasst lediglich eine Einzelleuchte 32 auf der Längsachse L- L. Das Einströmungsgehäuse 16 mit der oberen und unteren Einströmungsplatte 58, 60 ist abgesehen vom Bereich des peripheren Zwischenraums 62 kegelstumpfförmig ausgebildet. Der zwischen den beiden Gehäusen verlaufende Ansaugschlitz 76 weitet sich in Richtung des Zentralkanals 54 kontinuierlich, am Schluss stark auf.The embodiment according to FIG. 4 essentially corresponds to FIG. 1. The room lamp 10 comprises only a single lamp 32 on the longitudinal axis L. The inflow housing 16 with the upper and lower inflow plates 58, 60 is designed in the shape of a truncated cone, apart from the area of the peripheral intermediate space 62 . The suction slot 76 extending between the two housings widens continuously in the direction of the central channel 54, at the end greatly.
Entsprechend Fig. 1 ist die zentrale Öffnung in der unteren Einströmungsplatte 60, gebildet durch den abgewinkelten Rand 68, mit einem aufschraubbaren Aufsatzdeckel 70 verschlossen. Mit diesem Aufsatzdeckel 70 können, entsprechend Fig. 1 , Absaugöffnungen 74 für die verbrauchte Raumluft geöffnet, ge- schlössen oder bezüglich des Durchtrittsquerschnitts reguliert werden.1, the central opening in the lower inflow plate 60, formed by the angled edge 68, is closed with a screw-on cover 70. 1, suction openings 74 for the used room air can be opened, closed or regulated with respect to the passage cross section.
Fig. 5 zeigt einen Schnitt durch eine scheibenförmige Einsatzplatte 80, welche zwischen der oberen und unteren Einströmungsplatte 58, 60 gemass Fig. 1 einsetzbar ist. Der kreisförmige Umfang 81 entspricht den äusseren Abmes- sungen der Einströmungsplatten 58, 60. Die Innenbegrenzung 79 entspricht wenigstens dem Zentralkanal 54 (Fig. 1 ). In der Ausführungsform gemass Fig. 1 eingesetzt, endet die Eiπsatzplatte 80 dort, wo sich der Ansaugschlitz 76 aufweitet.FIG. 5 shows a section through a disk-shaped insert plate 80 which can be inserted between the upper and lower inflow plates 58, 60 according to FIG. 1. The circular circumference 81 corresponds to the outer dimensions of the inflow plates 58, 60. The inner boundary 79 corresponds at least to the central channel 54 (FIG. 1). Used in the embodiment according to FIG. 1, the insert plate 80 ends where the suction slot 76 widens.
Die vier grossen Bohrungen 82 in der Einsatzplatte 80 entsprechen den gemass Fig. 1 durch sie hindurch geführten Vertiefungen 64, die sechs kleinen Bohrungen 84 werden gemass Fig. 1 von den Schrauben 78 durchgriffen.The four large bores 82 in the insert plate 80 correspond to the depressions 64 passed through them in accordance with FIG. 1, the six small ones Bores 84 are penetrated by the screws 78 according to FIG. 1.
Von wesentlicher Bedeutung ist die Ausbildung von Strömungskanälen 86, mit Eintrittsöffnungen 87, welche im wesentlichen sternförmig angeordnet, jedoch um die grossen Bohrungen 82 herum geführt sind. Durch diese Strömungskanäle 86 wird die Raumluft, wie durch A angedeutet, in horizontaler Richtung angesaugt und in den Zentralkanal 54 (Fig. 1 ) weitergeführt. Durch die Ausbildung von Strömungskanälen 86 kann die Raumluftfiltrierung der Raumleuchte noch effizienter und räumlich gezielter eingesetzt werden.The formation of flow channels 86 with inlet openings 87, which are arranged essentially in a star shape, but are guided around the large bores 82, is of essential importance. Through these flow channels 86, the room air, as indicated by A, is sucked in in the horizontal direction and passed into the central channel 54 (FIG. 1). The formation of flow channels 86 enables the room air filtration of the room lamp to be used even more efficiently and in a more spatially targeted manner.
Die Strömungskanäle 86 sind in Form von Nuten, welche mit der oberen und/oder unteren Einströmungspiatte 58, 60 (Fig. 1 ) zusammenwirken, oder in Form von Kanälen ausgebildet, je nach dem Material und dem Herstellungsverfahren der Platte. Grundsätzlich kann die Einsatzplatte 80 aus jedem geeig- neten Material hergestellt sein, beispielsweise aus einem kompakten oder geschäumten Kunststoff, aber auch einem Metall oder einem Schaummetall.The flow channels 86 are in the form of grooves which cooperate with the upper and / or lower inflow plates 58, 60 (FIG. 1) or in the form of channels, depending on the material and the manufacturing method of the plate. In principle, the insert plate 80 can be made from any suitable material, for example from a compact or foamed plastic, but also from a metal or a foam metal.
Selbstverständlich kann die Einsatzplatte 80 auch eine andere als eine Scheibenform annehmen, je nach der Geometrie des Ansaugschlitzes 76 (Fig. 1 , 4). Auch kann sich die Einsatzplatte 80 in radialer Richtung nur über einen Teil erstrecken, insbesondere über den äussersten Bereich im Zwischenraum 62 (Fig 1 ,4).Of course, the insert plate 80 can also assume a shape other than a disk, depending on the geometry of the suction slot 76 (FIGS. 1, 4). The insert plate 80 can also extend only over a part in the radial direction, in particular over the outermost region in the intermediate space 62 (FIGS. 1, 4).
In Fig. 6 ist der mit einem Aufsatzdeckel 70 verschlossene Zentralkanal 54 im Detail dargestellt. Auf der unteren Einströmungsplatte 60 ist eine Einsatzplatte 80 gemass Fig. 5 angedeutet. In Richtung der Längsachse L-L bildet die untere Einströmungsplatte 60 den zylinderförmigen Rand 68. In diesem Rand 68 sind Absaugöffnungen 74 für die Raumluft A ausgebildet. Die Aussenseite des Randes 68 hat ein Innengewinde, in welches ein entsprechendes Aussenge- winde des Deckels 70 eingreift. Mit einem Pfeil 90 ist angedeutet, dass je nach der Einschraubtiefe des Aufsatzdeckels 70 mehr oder weniger Absaugungen 74 freigelegt oder verschlossen werden können. Damit ist die Absaugmenge von Raumluft A einstellbar. 6 shows the central channel 54 closed with a top cover 70 in detail. An insert plate 80 according to FIG. 5 is indicated on the lower inflow plate 60. In the direction of the longitudinal axis LL, the lower inflow plate 60 forms the cylindrical edge 68. In this edge 68, suction openings 74 for the ambient air A are formed. The outside of the edge 68 has an internal thread, in which a corresponding external thread of the cover 70 engages. An arrow 90 indicates that, depending on the screw-in depth of the top cover 70, more or fewer suction devices 74 can be exposed or closed. The suction quantity of room air A is adjustable.
