Description

Die vorliegende Erfindung betrifft einen Backofen mit einer Wrasenöffnung in einer Muffelwand, in deren Bereich ein Filter bzw. ein Katalysator in einem Filtergehäuse angeordnet ist, und mit einem Sauggebläse, das den Wrasen durch das Filter aus der Backofenmuffel zieht und aus dem Backofen drückt.The present invention relates to an oven having a vapor opening in a muffle wall, in whose area a filter or a catalyst in one Filter housing is arranged, and with a suction fan, the vapors through the filter from the oven muffle pulls and pushes out of the oven.

Ein derartiger Backofen ist z.B. aus der EP-A- 831 277 bekannt, wobei eine einfache Montage des Filter- bzw. Katalysatorgehäuses ohne Beschädigungen der Muffelwand im Bereich der Wrasenöffnung problematisch ist. Beispielsweise führen Verschraubungen oder ungünstige Berührstellen zwischen dem Filtergehäuse und der emaillierten Muffelwand bei der thermischen Beanspruchung der Backofenmuffel zu Emailleabplatzern. Auch ist die Montage des Filtergehäuses und die Entnahme des Filters durch eine Bedienperson nur umständlich möglich.Such a baking oven is e.g. known from EP-A-831 277, wherein a simple assembly of the Filter or catalyst housing without damaging the muffle wall in Area of Wrasenöffnung is problematic. For example, lead Screw connections or unfavorable contact points between the filter housing and the enamelled muffle wall in the thermal stress of the Oven muffle to enamel flakes. Also, the assembly of the filter housing and the removal of the filter by an operator only cumbersome.

Aufgabe der vorliegenden Erfindung ist es, einen Backofen nach dem Oberbegriff des Patentanspruches 1 derart zu verbessern, daß die Montage und Halterung des Filtergehäuses die Gebrauchseigenschaften des Backofens nicht beeinträchtigen.Object of the present invention is an oven according to the preamble of claim 1 to improve such that the assembly and mounting of the filter housing does not affect the operating characteristics of the oven affect.

Erfindungsgemäß ist dies bei einem Backofen mit den Merkmalen des Patentanspruches 1 erreicht. Durch die Befestigung des Filtergehäuses an einem separaten besonders geeigneten Montageteil ist insbesondere die emaillierte Muffelinnenwand vor mechanischen Beeinträchtigungen geschützt. Außerdem ist eine einfache und dichte Befestigung des Filtergehäuses im Bereich der Wrasenöffnung möglich.This is according to the invention in an oven with the features of Patent claim 1 achieved. By attaching the filter housing to a separate particularly suitable Mounting part is especially the enameled muffle inner wall from mechanical damage protected. In addition, a simple and tight attachment of the Filter housing in the field of Wrasenöffnung possible.

Gemäß einer bevorzugten Ausführungsform dient eine Bodenplatte eines Ausblaskanals des Sauggebläses als das Montageteil. Dies ist fertigungstechnisch besonders einfach und führt weiterhin zu einer dichten Verbindung zwischen dem Filtergehäuse und dem Ausblaskanal. Ein nachteiliges Austreten von Wrasen in den Gehäusezwischenraum zwischen Backofenmuffel und Gehäuse des Backofens ist mit einfachen Mitteln vermieden. Beispielsweise kann ein zusätzlicher Dichtschlauch, der die Wrasenöffnung mit einer Ansaugöffnung des Ausblaskanals verbindet, entfallen. Auch ergibt sich erfindungsgemäß ein besonders flacher Aufbau.According to a preferred embodiment, a bottom plate of a blow-out channel is used the suction fan as the mounting part. This is special in terms of manufacturing technology easy and still leads to a tight connection between the filter housing and the blow-out channel. A disadvantageous escape of vapor into the housing gap between oven muffle and oven cabinet is with simple Avoided funds. For example, an additional sealing tube, the Wrasenöffnung with a suction port of the Ausblaskanals connects omitted. Also results According to the invention, a particularly flat structure.

Vorteilhafterweise weist das Filtergehäuse einen Gehäuseboden und einen Gehäusedeckel auf, wobei der Gehäusedeckel an der Montageplatte befestigt ist, und der Gehäuseboden einfach lösbar an dem Gehäusedeckel gehaltert ist. Dies ermöglicht herstellungstechnisch eine einfache und dichte Verbindung zwischen dem Filtergehäuse und insbesondere dem Ausblaskanal des Sauggebläses. Zudem ist der Austausch des Filters bzw. des Katalysators durch die Bedienperson auf einfache Weise möglich. Durch die Zweiteilung des Filtergehäuses ist außerdem eine Steigerung der Dichtigkeit der gesamten Anordnung erreicht, da der Gehäusedeckel dicht im Randbereich der Wrasenöffnung an der Muffelinnenwand anliegt und der relativ zum Gehäusedeckel bewegliche Gehäuseboden mit geeigneten Dichtflächen versehen die dichte Verbindung zum Gehäusedeckel herstellt.Advantageously, the filter housing has a housing bottom and a housing cover on, with the housing cover is fixed to the mounting plate, and the housing bottom simply releasably supported on the housing cover. This allows manufacturing technology a simple and tight connection between the filter housing and in particular the exhaust duct of the suction fan. In addition, the exchange of the Filters or the catalyst by the operator in a simple manner possible. Due to the division of the filter housing is also an increase in the tightness the entire arrangement achieved because the housing cover close to the edge of the Wrasenöffnung rests against the muffle inner wall and the relative to the housing cover movable caseback with suitable sealing surfaces provide the tight connection produces to the housing cover.

Zur Vereinfachung der Montage des Filters ist der Gehäuseboden topfförmig ausgebildet.To simplify the installation of the filter, the housing bottom is cup-shaped.

Weiterhin ist eine Vereinfachung der werksseitigen Montage des Gehäusefilters dadurch erreicht, daß der Gehäusedeckel spezielle Haltemittel zum losen Einhängen bzw. Vormontieren in der Wrasenöffnung der Muffelwand der Backofenmuffel aufweist.Furthermore, a simplification of the factory mounting of the housing filter is characterized ensures that the housing cover special holding means for loose mounting or pre-assembled in the vapor opening of the muffle wall of the oven muffle having.
