Abstract

In the support of heating devices, e.g. of a grill heating element inside a baking oven, it has to be taken into consideration that very great temperature variations from 20 DEG C to over 500 DEG C occur during pyrolytic self-cleaning operation, associated with considerable material expansions and great forces at the connection points between heating element and baking oven. For microwave operation, it is important that there are no leaks at the fastening points and that none arise as a result of temperature loading. According to the invention, there is provided as fastening element a bolt which extends through the oven wall and which is on the one hand supported on the metal outside of the oven wall and on which on the other hand, inside the baking oven, a bearing element for the heating device and a bracing element are secured, which bracing element is braced with the bolt in a contacting manner. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Halterung für eine Heizeinrichtung in einem Backofen, vorzugsweise Mikrowellen-Backofen, gemäß dem Oberbegriff des Patentanspruches 1 (siehe u.a. DE-C-3028 352).The invention relates to a holder for a heating device in an oven, preferably a microwave oven, according to the preamble of claim 1 (see, inter alia, DE-C-3028 352).

Bei einem bekannten Mikrowellenofen (DE 30 28 352 C2) ist durch eine Öffnung in der Ofenwand hindurch ein Teil einer Heizeinrichtung, nämlich ein Schutzrohr für einen Temperaturfühler vom Ofeninnenraum bis außerhalb des Ofenraumes verlegt und mittels Schraubverbindung an der Ofenwand befestigt. Zur sicheren metallischen Kontaktierung zwischen Schutzrohr und Ofenwand dient eine elastische und Spreizlappen aufweisende Kontaktfolie, die von außen her auf das Schutzrohr aufgesteckt ist unter Verspreizung der Spreizlappen bis zur Anlage an der unbeschichteten Außenseite der Ofenmuffel. Hierbei hat die Montage und Demontage z.B. bei der Durchführung von Reparaturarbeiten von der Ofenaußenseite her zu erfolgen, was im Reparaturfall eine Entfernung der Ofenmuffel aus ihrem Außengehäuse erfordert. Bei Mikrowellenöfen ist es ferner bekannt (DE 30 35 747 C2), für die Halterung von Heizelementen, z.B. eines Grillheizkörpers, keramische Stützelemente zu verwenden, die mittels mit dem Grillheizkörper nicht metallisch verbundener metallischer Halterungen in Form von Stecklaschen an der Ofenwand befestigt sind. Die Erfahrung hat gezeigt, daß diese keramischen Körper Mikrowellen absorbieren und damit die nutzbare Mikrowellenleistung reduzieren und im übrigen bei mnechanischer Einwirkung bruchempfindlich sind. Schließlich ist es bei einem Backofen mit integrierter Mikrowellen-Einrichtung bekannt (DE-GM 88 12 765), einen Grillheizkörper in weitgehend loser Ankopplung auf Tragstäben zu lagern und diese Tragstäbe einzeln an der Muffelwand starr zu befestigen.In a known microwave oven (DE 30 28 352 C2), part of a heating device, namely a protective tube for a temperature sensor, is laid through an opening in the oven wall and extends from the oven interior to the exterior of the oven and is fastened to the oven wall by means of a screw connection. For reliable metallic contact between the protective tube and the furnace wall, there is an elastic contact film with spreading tabs, which is attached to the protective tube from the outside, with the spreading tabs spreading until it lies against the uncoated outside of the furnace muffle. In this case, assembly and disassembly, for example when carrying out repair work, must be carried out from the outside of the furnace, which in the event of repair requires removal of the furnace muffle from its outer housing. In the case of microwave ovens, it is also known (DE 30 35 747 C2) to use ceramic support elements for holding heating elements, for example a grill radiator, which are fastened to the oven wall by means of metallic brackets in the form of plug-in tabs which are not metallically connected to the grill radiator. Experience has shown that these ceramic Bodies absorb microwaves and thus reduce the usable microwave power and are otherwise susceptible to breakage when exposed to mechanical stress. Finally, it is known in an oven with an integrated microwave device (DE-GM 88 12 765) to mount a grill radiator in largely loose coupling on supporting rods and to rigidly attach these supporting rods individually to the muffle wall.

Der Erfindung liegt die Aufgabe zugrunde, eine Halterung für eine Heizeinrichtung in einem an der Innenseite mit einer Beschichtung, z.B. mit Email versehenen Backofen so zu verbessern, daß auch bei extremen Temperaturschwankungen eine dauerhafte, exakte Befestigung der Heizeinrichtung gewährleistet und Mikrowellentauglichkeit gegeben ist unter besonderer Berücksichtigung einer einfachen und kostensparenden Montage und Demontage.The invention has for its object to provide a holder for a heating device in a coating on the inside, e.g. to improve the oven provided with enamel so that even with extreme temperature fluctuations a permanent, exact attachment of the heating device is guaranteed and microwave suitability is given with special consideration of simple and cost-saving assembly and disassembly.

Diese Aufgabe wird erfindungsgemäß gelöst durch die im Kennzeichnungsteil des Patentanspruches 1 angegebenen Maßnahmen. Vorteilhafte ausgestaltungen der Erfindung ergeben sich aus den nachfolgenden Patentansprüchen.This object is achieved by the measures specified in the characterizing part of claim 1. Advantageous refinements of the invention result from the following patent claims.

Die erfindungsgemäße Halterung ist dazu geeignet, Reparaturarbeiten an der Heizeinrichtung, also eine Domontage z.B. des Grillheizkörpers von der Innenseite des Backofens aus vorzunehmen. Durch das Vorhandensein des Spreizelementes wird zum einen eine dauerhafte elastische Verbindung zwischen der Heizeinrichtung bzw. dessen Tragelement und der Ofenwand auch bei extremen Temperaturverhältnissen, z.B. bei pyrolytischem Selbstreinigungsbetrieb, erreicht und gleichzeitig ist gewährleistet, daß eine innige metallische Ankopplung des Heizelementes und seines Tragelementes an eine metallische Fläche der Ofenwand erhalten und aufrecht erhalten wird. Hierbei folgt dieser metallische Kontakt vom Innenraum des Backofens her über den mit dem Spreizelement verspreizten Bolzen zur emailfreien Außenseite der Ofenwand. Diese Halterung eignet sich gleichermaßen für die Befestigung von thermischen Heizkörpern wie für andere Teile einer Heizeinrichtung wie z.B. für einen Temperaturfühler oder dessen Schutzrohr.The holder according to the invention is suitable for carrying out repair work on the heating device, that is to say a domontage, for example of the grill element, from the inside of the oven. The presence of the expansion element on the one hand achieves a permanent elastic connection between the heating device or its support element and the furnace wall even under extreme temperature conditions, for example in pyrolytic self-cleaning operation, and at the same time it ensures that an intimate metallic coupling of the heating element and its support element to one Maintain and maintain the metallic surface of the furnace wall is obtained. This metallic contact follows from the interior of the oven via the bolt spread with the expansion element to the enamel-free outside of the oven wall. This bracket is equally suitable for attaching thermal radiators as for other parts of a heating device such as a temperature sensor or its protective tube.

Gemäß einer bevorzugten Ausgestaltung der Erfindung besitzt der Bolzen im Bereich der Spreizlappen eine Ringnut, in die die ungespreizten Spreizlappen eingreifen und sich die gespreizten Spreizlappen darin verspannen. Damit erhält man bei der Montage der Halterung eine Montagehilfe durch Vorjustierung des Spreizelementes und bei Reparaturarbeiten wird das Spreizelement in dieser Ringnut gehalten und am Herabfallen gehindert.According to a preferred embodiment of the invention, the bolt has an annular groove in the area of the spreading tabs, into which the unspread spreading tabs engage and the spreading tabs brace therein. This provides an assembly aid when the bracket is assembled by pre-adjusting the expansion element and during repair work the expansion element is held in this annular groove and prevented from falling.

Ebenfalls als Montagehilfe dienen am Tragelement vorgesehene, durch Hochbiegen der Begrenzungskanten der Tragelemente-Druckfläche geschaffene Anschläge, die eine Verspannung des Spreizelementes nur bis zu einem gewissen, die Elastizität des Spreizelementes erhaltenden Grad zulassen.Also used as an assembly aid are stops provided on the support element, which are created by bending up the boundary edges of the support element pressure surface and only allow the expansion element to be braced to a certain extent, which maintains the elasticity of the expansion element.

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 Fig. 1 bis 3 zeigen die z.B. obere, deckseitige Ofenwand 1 eines Backofens, vorzugsweise mit integrierter Mikrowellen-Heizeinrichtung, die im Bereich einer nachstehend beschriebenen Halterung eine z.B. kreisförmige Ausprägung 2 besitzt. Diese Ofenwand besitzt, wie die Fig. 2 und 3 zeigen, an der Innenseite eine Beschichtung 3 in Form einer Emailschicht, nicht jedoch an der gegenüberliegenden Außenseite. Mit 4 ist ein Heizelement einer thermischen Heizeinrichtung in Form eines Grillheizkörpers bezeichnet, der mittels Blechlaschen 5 an Tragstäben 6 befestigt ist, wobei diese thermische Heizeinrichtung sich mit geringem Abstand unmittelbar unterhalb der oberen Ofenwand befindet. Zur Befestigung der Tragstäbe 6 an der Ofenwand 1/2 dienen laschenartige Tragelemente 7, von denen in der Zeichnung nur eines dargestellt ist. Dieses metallische Tragelement 7 ist an der Unterseite unmittelbar mit dem Tragstab 6 verbunden, z.B. verschweißt und besitzt an dem der Ofenwand 1/2 zugewandten Ende einen rechtwinkelig abgebogenen Ansatz 8 mit einer der Ofenwand 1/2 zugewandten Druckfläche 9. Das Tragelement 7 besitzt einen den Ansatz 8 und die Druckfläche 9 teilenden Einschnitt 10, der sich am Tragelement 7 zum Tragstab 6 hin ein Stück weit fortsetzt. Zur Befestigung des Tragelementes 7 dient ein als Gewindebolzen ausgeführter Bolzen 11, der mit einer Ringnut 12 versehen ist und unterhalb der Ringnut ein Außengewinde besitzt, auf das eine Gewindemutter windemutter 23 mit Unterlegscheibe 13 aufschraubbar ist. Der Bolzen 11 besitzt einstückig einen breiten Kopfteil 14, der platten- bzw. scheibenförmig ausgebildet ist und eine senkrecht abgebogene Nase 15 als Verdrehsicherung besitzt, die zu diesem Zweck in eine Öffnung 16 der Ofenwand 1/2 eingreift. Auf den Bolzen 11 vom Innenraum des Backofens aus aufgesteckt ist ein Spreizelement 17 (siehe auch Fig.5), das in Form einer kreisrunden Scheibe ausgebildet ist und konzentrische Wölbungen oder Wellungen 18 aufweist. Das Spreizelement 17 besitzt im Mittelbereich winkelig abgebogene, durch kreuzförmigen Freischnitt 19 erzeugte Spreizlappen, die im ungespreizten Zustand in den Bereich der Ringnut 12 eingreifen (Montagesituation gemäß Fig. 2). Der Bolzen 11 befindet sich in dem vorerwähnten Einschnitt 10 des Tragelementes 7. Mit dem Anziehen der Gewindemutter 12 wird das Tragelement mit seinem geteilten Ansatz 8 in Richtung der Ofenwand 1/2 gedrückt, wobei die ebenfalls geteilte Druckfläche 9 das Spreizelement gegenüber der emaillierten Oberfläche der Ofenwand 1/2 verspannt. Wie deutlich aus den Fig. 2 und 3 zu ersehen, sind die gegenüberliegenden Begrenzungskanten der Druckfläche 9 in Richtung der Ofenwand 1/2 abgewinkelt unter Bildung von auf diese Weise gebildeten Anschlägen 21. Durch diese Anschläge 21 wird beim Anziehen der Gewindemutter 12 ein definierter Abstand zwischen Druckfläche 9 und Beschichtung 3 der Ofenwand 1/2 sichergestellt, so daß eine elastische Verformung der Wölbungen oder Wellungen 18 des Spreizelementes 17 nur bis zu einem gewissen, die Elastizität des Spreizelementes erhaltenden Grade erfolgt. Nach dem Anziehen der Gewindemutter 23 (Montagesituation gemäß Fig. 3) verspreizen sich die Spreizlappen 20 radial nach innen und kontaktieren metallisch mit der Oberfläche der Ringnut 12. Auf diese Weise ist eine dauerhafte und bei allen Temperaturverhältnissen gleichbleibend sichere metallische Kontaktierung zwischen dem Heizelement über dessen Tragelement, über das Spreizelement 17, über den Bolzen 11 und schließlich über den Kopfteil 14 zur nicht-beschichteten Außenfläche der Ofenwand 1/2 hergestellt. Bei Mikrowellenbetrieb des Backofens wird damit eine Leckstrahlung z.B. durch die Öffnung 22 in der Ofenwand 1/2 hindurch, die zum Hindurchstecken des Bolzens 11 dient, in sicherer Weise verhindert.It shows

1 to 3 show, for example, the upper, top-side oven wall 1 of an oven, preferably with an integrated microwave heating device, which has, for example, a circular shape 2 in the area of a holder described below. As shown in FIGS. 2 and 3, this furnace wall has a coating 3 in the form of an enamel layer on the inside, but not on the opposite outside. 4 with a heating element of a thermal heating device in the form of a grill heater is designated, which is fastened by means of sheet metal brackets 5 to support rods 6, this thermal heating device being located at a short distance immediately below the upper furnace wall. To fasten the support rods 6 to the furnace wall 1/2, tab-like support elements 7 are used, of which only one is shown in the drawing. This metallic support element 7 is connected at the bottom directly to the support rod 6, for example welded, and has at the end facing the furnace wall 1/2 a right-angled extension 8 with a pressure surface 9 facing the furnace wall 1/2. The support element 7 has a Approach 8 and the pressure surface 9 dividing incision 10, which continues to a certain extent on the support element 7 towards the support rod 6. For fastening the support element 7 is used as a threaded bolt 11, which is provided with an annular groove 12 and has an external thread below the annular groove, on which a threaded nut 23 with nut washer 13 can be screwed. The bolt 11 has in one piece a wide head part 14, which is plate-shaped or disk-shaped and has a vertically bent nose 15 as a means of preventing rotation, which for this purpose engages in an opening 16 in the furnace wall 1/2. A spreading element 17 (see also FIG. 5), which is designed in the form of a circular disk and has concentric curvatures or corrugations 18, is plugged onto the bolt 11 from the interior of the oven. The spreading element 17 has, in the central region, angularly bent spreading flaps which are produced by a cross-shaped free cut 19 and which engage in the region of the annular groove 12 in the non-spread state (assembly situation according to FIG. 2). The bolt 11 is located in the above-mentioned notch 10 of the support element 7. When the threaded nut 12 is tightened, the support element with its divided shoulder 8 is pressed in the direction of the furnace wall 1/2, the likewise divided pressure surface 9 being the expansion element relative to the enamelled surface of the Oven wall 1/2 braced. As can be clearly seen from FIGS. 2 and 3, the opposite boundary edges of the pressure surface 9 are angled in the direction of the furnace wall 1/2 to form stops 21 formed in this way. These stops 21 provide a defined distance when the threaded nut 12 is tightened ensured between the pressure surface 9 and the coating 3 of the furnace wall 1/2, so that an elastic deformation of the curvatures or corrugations 18 of the expansion element 17 takes place only to a certain extent, which maintains the elasticity of the expansion element. After tightening the threaded nut 23 (assembly situation according to FIG. 3), the spreading lugs 20 spread radially inward and make metallic contact with the surface of the annular groove 12. In this way, permanent and constant, reliable contact at all temperature conditions between the heating element via its support element, via the spreading element 17, over the bolt 11 and finally over the head part 14 to the non-coated outer surface of the furnace wall 1/2. During microwave operation of the oven, leakage radiation, for example through the opening 22 in the oven wall 1/2, which serves to push the pin 11 through, is thus reliably prevented.
