Description

Die Erfindung bezieht sich auf eine Leuchte für Backöfen gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a lamp for ovens according to the preamble of claim 1.

Bei bekannten Leuchten dieser Art (DE-41 21 886 A1 bzw EP-A-0 521 248) ist innerhalb eines, einen Reflektor bildenden Leuchtengehäuses eine Lampenfassung mit Lampe angeordnet, wobei die Leuchtenkammer gegenüber dem Backofeninnenraum verschlossen ist durch eine, eine Glasplatte aufweisende Abdeckung, die sich unter Zwischenlage einer elastischen Dichtung, insb. einer Silikondichtung, an einem Randflansch des Leuchtengehäuses abstützt. Durch dieses Dichtungselement soll der Eintritt von bei Betrieb des Backofens entstehendem Wrasen in das Innere der Leuchte verhindert werden. Es besteht jedoch hierbei die Schwierigkeit, daß bei erhöhter Ofentemperatur, z.B. bei pyrolytischer Selbstreinigung unter Erhitzung des Backofeninnenraumes auf nahezu 100° C das Dichtungselement dieser Temperatur nicht standhält und zerstört wird.In known lamps of this type (DE-41 21 886 A1 or EP-A-0 521 248), a lamp holder with lamp is arranged within a lamp housing forming a reflector, the lamp chamber being closed off from the interior of the oven by a cover having a glass plate , which is supported on an edge flange of the lamp housing with the interposition of an elastic seal, especially a silicone seal. This sealing element is intended to prevent vapors from entering the lamp when the oven is in operation. However, there is the difficulty that at an elevated oven temperature, e.g. in the case of pyrolytic self-cleaning while the interior of the oven is heated to almost 100 ° C., the sealing element does not withstand this temperature and is destroyed.

Der Erfindung liegt die Aufgabe zugrunde, die Leuchte mit einer derartigen Abdeckung auszustatten, daß auch unter der Einwirkung extrem hoher Temperaturen die Wrasendichtheit der Leuchte erhalten bleibt und die Zerstörung eines Dichtungselementes nicht zu befürchten ist.The invention has for its object to provide the lamp with such a cover that the vapor tightness of the lamp is maintained even under the influence of extremely high temperatures and the destruction of a sealing element is not to be feared.

Aus DE-U-79 15 273 ist eine kraftschlüssig eingelegte ringförmige Metalldichtung bekannt. Diese kann beim Auswechseln der Lampe verloren gehen.From DE-U-79 15 273 a non-positively inserted annular metal seal is known. This can be lost when the lamp is replaced.

Dieses Problem wird gemäß der Erfindung gelöst durch die im Kennzeichnungsteil des Patentanspruches 1 aufgeführten Maßnahmen. Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den nachfolgenden Patentansprüchen.This problem is solved according to the invention by the measures listed in the characterizing part of claim 1. Advantageous embodiments of the invention result from the following patent claims.

Dadurch, daß gemäß der Erfindung als metallische Federwangen ausgebildete Dichtungselemente verwendet werden, ist eine schädliche Beeinflussung der Wrasendichtheit durch extreme Temperatureinwirkung in keiner Weise zu befürchten. Diese besonderen Dichtungselemente sind fester, unverlierbarer Bestandteil der ohne Anwendung eines Werkzeuges auch vom Laien bequem vom Leuchtengehäuse zu entfernenden Abdeckung. Diese Federwangen sind vorzugsweise Bestandteil eines metallischen Rahmens, der wiederum Rastelemente bildet für die Verrastung der Abdeckung am Leuchtengehäuse. Insgesamt ergibt sich erfindungsgemäß eine Leuchte, die sowohl wrasendicht ist als auch extrem hohen Temperaturen z.B. nigungstemperaturen standhalten kann.The fact that sealing elements designed as metallic spring cheeks are used according to the invention means that there is in no way a fear of damaging the vapor tightness due to extreme temperature effects. These special sealing elements are a firm, captive part of the cover, which can be easily removed from the luminaire housing without the use of a tool. These spring cheeks are preferably part of a metallic frame, which in turn forms locking elements for locking the cover on the lamp housing. Overall, according to the invention there is a luminaire which is both vapor-tight and extremely high temperatures e.g. can withstand temperatures.

Die Erfindung ist anhand eines in der Zeichnung dargestellten Ausführungsbeispieles nachstehend erläutert.The invention is explained below using an exemplary embodiment shown in the drawing.

Die in den Figuren 1 und 2 dargestellte Leuchte besitzt als Grundelement ein langgestrecktes Leuchtengehäuse 1, das eine Leuchtenkammer 2 umzieht, deren z.B. aus Aluminiummaterial bestehende, zu einer Seite hin gewölbte Wandung 3 im Inneren der Leuchtenkammer 2 einen Reflektor für von einer Lampe 4, vorzugsweise von einer Hochvolt-Halogenlampe herkommende Lichtstrahlen dient. Das Leuchtengehäuse 1 besitzt ein, einen unmittelbaren Bestandteil der Wandung 3 darstellenden Umfangsflansch 5 (Fig. 3), der eine rechteckförmige, langgestreckte Leuchtenöffnung 6 umzieht. In einer mit einer entsprechenden Öffnung versehenen, seitlichen Wandung 7 des Leuchtengehäuses 1 ist eine allgemein mit 8 bezeichnete Lampenfassung befestigt mit elektrischen Anschlußelementen 9, auf deren nicht dargestellte Kontaktelemente die Lampe 4 im Inneren der Leuchtenkammer 2 aufgesteckt ist. Die Leuchte ist mit ihrem Umfangsflansch 5 in eine Öffnung 10, z.B. der Seitenwand 11 einer nicht weiter dargestellten Backofenmuffel eingesetzt, derart, daß die Leuchtenöffnung 6 dem Innenraum 12 des Backofens zugewandt ist und das Leuchtengehäuse 1 außerhalb der Backofenmuffel liegt. Es ist in den Figuren nicht weiter dargestellt, daß der innenliegende Umfangsflansch 5 z.B. dadurch mit der Wandung 11 des Backofens verbunden ist, daß das Lampengehäuse 1 mit Abstand vom Umfangsflansch 5 federnde Krampen besitzt, die beim Eindrücken des Lampengehäuses 1 in die Öffnung 10 mit dem Öffnungsrand verrasten. In ebenfalls nicht dargestellter Weise kann der Backofen eingerichtet sein für eine sogenannte pyrolytische Selbstreinigung unter Verwendung von elektrischen Heizelementen in mittels welchen bei geschlossener Backofentür eine Erhitzung des Backofeninnenraumes bis auf eine Temperatur von nahezu 500°C ermöglicht wird. Allgemein mit 13 ist eine Abdeckung der Leuchte bezeichnet, die auf die Leuchtenöffnung 6 aufdrückbar und mit dem Leuchtengehäuse 1 verrastbar ist. Diese Abdeckung 13 kann auch vom Laien von Hand abgenommen werden, etwa zum Auswechseln der schadhaft gewordenen Lampe 4. Die als Einzelheit in Fig. 3 verdeutlichte Abdeckung 13 besteht aus einer randseitig leicht abgekröpften Glasplatte 14, die fest verbunden ist mit einem aus metallischem Federmaterial bestehenden Rahmen 15, der die dem Leuchtengehäuse 1 zugewandte Innenseite der Glasplatte 14 im Bereich der Abkröpfung 16 umzieht und mittels U-förmig gebogenen Ansätzen 17 zwei gegenüberliegende Randkanten 18 der Glasplatte 14 umgreift und damit fest und unverlierbar mit dieser Glasplatte 14 verbunden ist. Der vorgenannte Rahmen 15 besitzt in Höhe der rechteckförmigen Leuchtenöffnung 6 freiragende, zum Leuchtengehäuse 1 hin abgebogene und an den Enden gewölbte Federwangen 19, die abschnittsweise rechtwinkelig aufeinanderstehen und in den Ecken durch Schlitze 20 voneinander getrennt sind. Im Bereich dieser Federwangen 19 besitzt der metallische Rahmen 15 an gegenüberliegenden Seiten ebenfalls einstückig ausgeschnittene und ausgeformte, federnde Rastelemente 21, die im wesentlichen S-förmig und freiragend gebogen sind, wie insb. Fig. 3 zeigt und die zusammenwirken mit Gegenrastelementen 22 in Form von in der Wandung 3 des Leuchtengehäuses 1 vorgesehenen Rastöffnungen. Ferner sind federnde Zentrierelemente 21' als Bestandteile des Rahmens 15 vorgesehen, vorzugsweise an allen vier Seiten des Rahmens 15. Mit dem Aufdrücken der Abdeckung 13 auf die Leuchtenöffnung 6 stützen sich die metallischen Federwangen 19 federnd auf dem Umfangsflansch 5 des Leuchtengehäuses 1 ab, derart, daß diese Federwangen 19 ein Dichtungselement zwischen Abdeckung 13 und Leuchtengehäuse 1 bilden. Dabei wird die Abdeckung 13 durch die Zentrierelemente 21' gegenüber der Leuchtenöffnung 6 lagemäßig zentriert. Unmittelbar darauffolgend verrasten die Rastelemente 21 des Rahmens 15 in den Gegenrastelementen 22, so daß eine stabile aber dennoch leicht lösbare Befestigung der Abdeckung 13 hergestellt ist.The luminaire shown in FIGS. 1 and 2 has, as a basic element, an elongated luminaire housing 1, which moves a luminaire chamber 2, for example made of aluminum material Existing, to one side curved wall 3 inside the lamp chamber 2 serves a reflector for light rays coming from a lamp 4, preferably from a high-voltage halogen lamp. The luminaire housing 1 has a circumferential flange 5 (FIG. 3) which is a direct component of the wall 3 and which moves around a rectangular, elongated luminaire opening 6. In a side wall 7 of the lamp housing 1 provided with a corresponding opening, a lamp socket, generally designated 8, is fastened with electrical connection elements 9, on the contact elements (not shown) of which the lamp 4 is plugged inside the lamp chamber 2. The lamp is inserted with its peripheral flange 5 in an opening 10, for example the side wall 11 of an oven muffle, not shown, such that the lamp opening 6 faces the interior 12 of the oven and the lamp housing 1 is outside the oven muffle. It is not shown in the figures that the inner circumferential flange 5 is connected to the wall 11 of the oven, for example, in that the lamp housing 1 has resilient cramps at a distance from the circumferential flange 5, which when the lamp housing 1 is pressed into the opening 10 with the Lock the opening edge. In a manner also not shown, the oven can be set up for a so-called pyrolytic self-cleaning using electrical heating elements, by means of which heating of the interior of the oven to a temperature of almost 500 ° C. is made possible when the oven door is closed. In general, 13 denotes a cover of the lamp, which can be pressed onto the lamp opening 6 and locked with the lamp housing 1. This cover 13 can also be removed by the layperson by hand, for example to replace the lamp 4 which has become defective. The cover 13, which is illustrated as a detail in FIG. 3, consists of a slightly bent at the edge of the glass plate 14, which is firmly connected to a frame 15 made of metallic spring material, which moves around the inside of the glass plate 14 facing the lamp housing 1 in the region of the offset 16 and by means of U-shaped lugs 17 two opposite edge edges 18 of the glass plate 14 engages and is thus firmly and captively connected to this glass plate 14. The aforementioned frame 15 has at the height of the rectangular lamp opening 6 cantilevered, bent towards the lamp housing 1 and at the ends curved spring cheeks 19, which are sections at right angles to each other and are separated from one another in the corners by slots 20. In the area of these spring cheeks 19, the metallic frame 15 also has, on opposite sides, one-piece cut and shaped, resilient locking elements 21, which are essentially S-shaped and cantilevered, as shown in FIG. 3 and which interact with counter-locking elements 22 in the form of provided in the wall 3 of the lamp housing 1 locking openings. Furthermore, resilient centering elements 21 'are provided as components of the frame 15, preferably on all four sides of the frame 15. When the cover 13 is pressed onto the lamp opening 6, the metallic spring cheeks 19 are resiliently supported on the peripheral flange 5 of the lamp housing 1, that these spring cheeks 19 form a sealing element between cover 13 and lamp housing 1. The cover 13 is centered in position by the centering elements 21 'relative to the lamp opening 6. Immediately afterwards, the latching elements 21 of the frame 15 latch in the counter latching elements 22, so that a stable but nevertheless easily detachable fastening of the cover 13 is produced.
