Description

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

Bei Mikrowellenöfen allgemein besteht die zwingende Forderung, daß eine Abstrahlung von Mikrowellenenergie außerhalb des für die Wärmebehandlung von Lebensmitteln vorgesehenen Ofenraumes verhindert werden muß. Bei Mikrowellenöfen mit Leuchteinrichtung zur Ausleuchtung des Ofenraumes besteht diesbezüglich die Problematik, daß für die Leuchtanordnung in der Ofenwandung eine mehr oder weniger große Öffnung vorgesehen sein muß, durch die hindurch Mikrowellenstrahlen nach außen austreten könnten, wenn sich die Lampe nicht in der Lampenfassung befindet und/oder wenn sich nicht eine besondere, mikrowellendichte Abschirmung in korrekter Stellung auf der vorgenannten Öffnung mit allseitigem metallischen Kontakt zur Ofenwandung befindet. Diese Gefahr besteht bei einem evtl. vorzunehmenden Lampenwechsel. Bei einem bekannten Mikrowellenherd (DE-PS 29 37 499) ist die vorgenannte Öffnung in der Ofenwandung mikrowellendicht verschließbar durch eine auf die Öffnung aufsetzbare transparente Abdeckung, die ein metallisches Schirmgitter enthält und in der Schließstellung in unmittelbarem Kontakt mit der Ofenwandung steht. Diese Abdeckung besitzt eine metallische Fassung für die Lampe und steht in Verbindung mit einem Sicherheitsschalter, derart, daß erst mit dem korrekten Einsetzen von Abdeckung und Fassung der Sicherheitsschalter betätigt wird und der Mikrowellengenerator des Mikrowellenofens einschaltbar ist.In microwave ovens in general, there is an imperative requirement that radiation of microwave energy outside the oven space provided for the heat treatment of food must be prevented. In the case of microwave ovens with lighting devices for illuminating the oven space, there is the problem in this respect that a more or less large opening must be provided for the lighting arrangement in the oven wall, through which microwave rays could escape to the outside when the lamp is not in the lamp holder and / or if there is not a special, microwave-proof shield in the correct position on the aforementioned opening with all-round metallic contact with the furnace wall. This danger exists if the lamp has to be changed. In a known microwave oven (DE-PS 29 37 499), the aforementioned opening in the oven wall can be closed in a microwave-tight manner by a transparent cover which can be placed on the opening and which contains a metallic screen grid and is in direct contact with the oven wall in the closed position. This cover has a metallic socket for the lamp and is connected to a safety switch, such that only with the correct insertion of Cover and socket of the safety switch is actuated and the microwave generator of the microwave oven can be switched on.

Der Erfindung liegt die Aufgabe zugrunde, eine Leuchte für Mikrowellenöfen so auszugestalten, daß sie auch ohne besonderen Sicherheitsschalter einen Austritt von Mikrowellenstrahlung bei einfacher konstruktiver Ausgestaltung auch bei unachtsamer Handhabung der Leuchte, z.B. beim Auswechseln der Lampe, verhindert.The invention has for its object to design a lamp for microwave ovens so that they emit microwave radiation without a special safety switch with a simple design even when careless handling of the lamp, e.g. when replacing the lamp, prevented.

Diese Aufgabe wird gemäß der Erfindung gelöst durch die im Kennzeichnungsteil des Patentanspruches 1 aufgeführten Maßnahmen. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den nachfolgenden Patentansprüchen.This object is achieved according to the invention by the measures listed in the characterizing part of claim 1. Further advantageous refinements of the invention result from the following patent claims.

Durch die erfindungsgemäße Anordnung einer selbsttätig rückstellbaren Abschirmung ist eine Situation, in welcher sich infolge unachtsamer Handhabung an der Leuchte eine Lecköffnung in der Ofenwandung bilden könnte, nicht mehr möglich, da sich nach jeder Handhabung an der Leuchte diese Öffnung wieder selbsttätig verschließt. Hierbei sind im Rahmen dieser technischen Lehre unterschiedliche Ausführungsvarianten denkbar, z.B. durch Ausgestaltung der Abschirmung in Form einer Klappe, eines verschiebbaren Gitters o.dgl.. Ebenso bestehen mannigfache Möglichkeiten in bezug auf die Rückstelleinrichtung einschließlich der Rückstellung der Abschirmung durch die Schwerkraft der Abschirmung selbst.Due to the inventive arrangement of an automatically resettable shield, a situation in which a leak opening in the furnace wall could form as a result of careless handling of the lamp is no longer possible, since this opening closes again automatically after each use on the lamp. Different versions are conceivable within the framework of this technical teaching, e.g. by designing the shield in the form of a flap, a sliding grille or the like. There are also numerous possibilities with regard to the resetting device, including the resetting of the shield by the gravity of the shield itself.

Die Erfindung ist anhand von in der Zeichnung dargestellten Ausführungsbeispielen nachstehend erläutert.The invention is explained below with reference to exemplary embodiments shown in the drawing.

Beim Ausführungsbeispiel gemäß Fig. 1 ist mit 1 ein Teil der Ofenwandung, z.B. der Seitenwand eines Mikrowellenofens an sich bekannter Art bezeichnet, welche einen allgemein bei 2 angedeuteten Ofenraum umschließt. Im Bereich einer Einprägung 3 besitzt diese Ofenwandung eine Öffnung 4, hinter der sich eine durch ein Leuchtengehäuse 5 gebildete bzw. umschlossene Leuchtenkammer 6 befindet. Das Leuchtengehäuse 5 ist mit einem dieses umziehenden Flansch 7 unmittelbar mit der Ofenwandung 1 z.B. durch Verschweißen verbunden. Auf dem Flansch 7 befindet sich eine elastische Dichtung 8. An der in Fig. 1 oberen Seitenwand des Leuchtengehäuses 5 ist eine elektrische Lampenfassung 9 für eine darin einsteckbare bzw. einschraubbare Lampe 10 befestigt. In Höhe der Öffnung 4 besitzt das Leuchtengehäuse am Umfang verteilt mehrere, federartig nach innen gebogene Rastelemente 11, auf die eine aus glasartigem Material bestehende, transparente Abdeckung 12 mit einem umlaufenden, am Außenumfang verengten Kragen 13 aufsteckbar und verrastbar ist und von den Rastelementen 11 entfernbar ist. Die Abdeckung 12 stützt sich an der Dichtung 8 ab und verschließt die Leuchtenkammer 6 zum Ofenraum 2 hin mechanisch, so daß bei Betrieb des Mikrowellenofens keine Verschmutzung der Leuchtenkammer 6 stattfinden kann. Mit 14 ist eine in Form eines metallischen, gitterartigen Korbes ausgestaltete Abschirmung bezeichnet, die in der Schließstellung gemäß Fig. 1 und 3 Lampenfassung 9 und Lampe 10 nach vier Seiten hin umschließt und sich unmittelbar an den Wandungsteilen des Leuchtengehäuses 5 abstützt und mit dem Leuchtengehäuse 5 in metallischen Kontakt tritt. Die Abschirmung 14 ist schwenkbar um eine Schwenkachse 15 an einem stationären Ofenteil, d.h. im vorliegenden Fall am stationären Leuchtengehäuse 5 angelenkt. Auf der Schwenkachse ist ferner eine Drehfeder 16 gelagert, die sich einerseits am Leuchtengehäuse 5 und andererseits an der Abschirmung 14 mit Vorspannung abstützt und die bewirkt, daß die korbartige Abschirmung 14 nach dem Verschwenken in die Öffnungsstellung gemäß Fig. 2, in welcher vom Ofenraum 2 her die Lampe 10 aus der Lampenfassung 9 entnommen werden kann, selbsttätig durch die Kraft der Drehfeder 16 wieder in die Schließstellung gemäß Fig. 1 gelangt. In dieser Schließstellung verrastet die Abschirmung 14 mit einem Randteil in einem U-förmigen Rastelement 17 gemäß Fig. 4, das im Bereich einer Einschnürung 18 am Leuchtengehäuse 5 befestigt ist. Wenn sich die Abschirmung 14 in der Schließstellung gemäß Fig. 1 und 3 befindet, können vom Ofenraum 2 herkommende Mikrowellenstrahlen nicht in den von der Abschirmung 14 und vom Leuchtengehäuse 5 im Bereich dieser Abschirmung metallisch umschlossenen Bereich der Leuchtenkammer 6 gelangen, indem sich die Lampenfassung 9 befindet.In the exemplary embodiment according to FIG. 1, 1 denotes part of the oven wall, for example the side wall of a microwave oven, of a type known per se, which surrounds an oven space, which is generally indicated at 2. In the area of an indentation 3, this furnace wall has an opening 4, behind which there is a lamp chamber 6 which is formed or enclosed by a lamp housing 5. The lamp housing 5 is connected directly to the furnace wall 1 by a flange 7 that surrounds it, for example by welding. An elastic seal 8 is located on the flange 7. An electrical lamp holder 9 for a lamp 10 which can be inserted or screwed therein is fastened to the upper side wall of the lamp housing 5 in FIG. 1. At the level of the opening 4, the luminaire housing has a plurality of snap-in elements 11, which are bent inward and spring-like on the circumference and onto which a transparent cover 12 made of glass-like material with a circumferential collar 13 constricted on the outer circumference can be attached and can be locked and can be removed from the locking elements 11. The cover 12 is supported on the seal 8 and mechanically closes the lamp chamber 6 to the furnace chamber 2, so that no contamination of the lamp chamber 6 can take place during operation of the microwave oven. 14 designates a shield in the form of a metallic, lattice-like basket, which in the closed position according to FIGS. 1 and 3 surrounds lamp holder 9 and lamp 10 on four sides and is supported directly on the wall parts of the lamp housing 5 and with the lamp housing 5 comes into metallic contact. The shield 14 can be pivoted about a pivot axis 15 on a stationary furnace part, ie in the present case on the stationary lamp housing 5. On the pivot axis there is also a torsion spring 16, which is supported on the one hand on the lamp housing 5 and on the other hand on the shield 14 with prestress and which causes the basket-like shield 14 after pivoting into the open position according to FIG. 2, in which the furnace chamber 2 forth the lamp 10 can be removed from the lamp holder 9, automatically returns to the closed position according to FIG. 1 by the force of the torsion spring 16. In this closed position, the shield 14 latches with an edge part in a U-shaped latching element 17 according to FIG. 4, which is fastened to the lamp housing 5 in the region of a constriction 18. If the shield 14 is in the closed position according to FIGS. 1 and 3, microwave rays coming from the furnace space 2 cannot reach the region of the lamp chamber 6 which is metallically enclosed by the shield 14 and the lamp housing 5 in the area of this shield by the lamp holder 9 located.

Beim Ausführungsbeispiel gemäß Fig. 5 ist in bezug auf die Ausführung gemäß Fig. 1 bis 4 unterschiedlich die Ausgestaltung der Abschirmung 14'. Hier ist diese Abschirmung nicht in Form eines Korbes ausgestaltet, sondern bildet ein im wesentlichen ebenes Gitter, das das Leuchtengehäuse 5 in seiner gesamten lichten Weite durchzieht und nach Abnehmen der Abdeckung 12 aus der Schließstellung gemäß Fig. 5 in Pfeilrichtung in eine Öffnungsstellung entgegen der Kraft der Drehfeder 16 um die Schwenkachse 15 verschwenkt werden kann. In dieser Öffnungsstellung ist wiederum die Lampe 10 frei zugänglich, wonach die Abschirmung 14' wieder selbsttätig sich in die Schließstellung bewegt.In the exemplary embodiment according to FIG. 5, the design of the shield 14 ′ differs with respect to the embodiment according to FIGS. 1 to 4. Here, this shielding is not designed in the form of a basket, but rather forms an essentially flat grid which runs through the lamp housing 5 in its entire clear width and after removing the cover 12 from the closed position according to FIG. 5 in the direction of the arrow into an open position against the force the torsion spring 16 can be pivoted about the pivot axis 15. In this open position, the lamp 10 is again freely accessible, after which the shield 14 'again moves automatically into the closed position.

Beim Ausführungsbeispiel gemäß Fig. 6 bilden die aus glasartigem Material bestehende, scheibenförmige Abdeckung 12' und die im wesentlichen ebene, durch Umbördelung der Ränder mit der Abdeckung 12' verbundene Abschirmung 14' einen einstückigen Bauteil, der um eine unmittelbar an der Ofenwandung 1 befestigte Schwenkachse 15 in Pfeilrichtung verschwenkbar ist, wobei dieser Bauteil wiederum durch Federkraft oder aber lediglich durch Schwerkraft nach dem Verschwenken in die Öffnungsstellung selbsttätig wieder in die Schließstellung mit großflächiger Anlage an der Ofenwandung 1 rückstellbar ist.In the exemplary embodiment according to FIG. 6, the disk-shaped cover 12 ', which is made of glass-like material, and the essentially planar shield 14', which is connected to the cover 12 'by flanging the edges, form a one-piece component which rotates about a pivot axis directly attached to the furnace wall 1 15 can be pivoted in the direction of the arrow, this component again being able to be automatically reset to the closed position with large-area contact with the furnace wall 1 by spring force or simply by gravity after the pivoting into the open position.
