Description

Die vorliegende Erfindung betrifft einen Backofen mit Mitteln zur pyrolytischen Selbstreinigung mit einem durch eine Tür verschließbaren und durch eine Backofenmuffel begrenzten Garraum, mit einem unterhalb der Deckwand der Muffel im Garraum angeordneten ersten Heizelement und einem der Bodenwand zugeordneten zweiten Heizelement, dessen Heizleistung beim Pyrolysebetrieb wesentlich größer ist als die des ersten Heizelementes.The present invention relates to an oven with means for pyrolytic self-cleaning with a lockable by a door and limited by an oven muffle Cooking space, with one arranged below the top wall of the muffle in the cooking space first heating element and a second heating element assigned to the bottom wall, the Heating power in pyrolysis mode is significantly greater than that of the first heating element.

Ein derartiger Backofen ist bekannt aus der Druckschrift US 3,668,371, wobei im Garraum unterhalb der Deckwand und oberhalb der Bodenwand der Muffel jeweils ein Rohrheizkörper für den Garbetrieb vorgesehen ist. Beim Selbstreinigungsbetrieb wird das erste Heizelement vom Netz getrennt, während das zweite Heizelement an Netzspannung gelegt ist. Dabei stellt sich im Schwerpunkt der Backofenmuffel eine Temperatur von etwa 320°C im Unterschied zu der beim Pyrolysebetrieb ansonsten üblicherweise erreichten Schwerpunktstemperatur von 450°C ein. Die mit der gemäß der Druckschrift US 3,668,371 deutlich reduzierten Schwerpunktstemperatur verbundenen relativ niedrigen Muffelwandtemperaturen sind jedoch im Bereich der weniger verschmutzten Muffelseitenwände und -deckwand für eine Reinigung ausreichend groß. Infolge der unmittelbaren räumlichen Nähe des zweiten Heizelementes zur Bodenwand wird diese deutlich stärker aufgeheizt, typischerweise auf bis zu etwa 450°C. Diese Temperatur ist geeignet, um den üblicherweise stärker verschmutzten Bodenbereich der Backofenmuffel pyrolytisch reinigen zu können.Such an oven is known from the publication US 3,668,371, in which Cooking space below the top wall and above the bottom wall of the muffle Tubular heating element is provided for cooking. In self-cleaning mode, that will be first heating element disconnected from the mains, while the second heating element on mains voltage is laid. The focus of the oven muffle is about a temperature 320 ° C in contrast to that normally achieved in pyrolysis operation Center of gravity temperature of 450 ° C. The with the according to the publication US 3,668,371 significantly reduced center of gravity associated relatively low Muffle wall temperatures are, however, in the area of the less soiled muffle side walls and cover wall large enough for cleaning. As a result of the immediate spatial proximity of the second heating element to the bottom wall, this becomes significantly stronger heated, typically up to about 450 ° C. This temperature is suitable for the Usually heavily soiled bottom area of the oven muffle pyrolytically to be able to clean.

Aufgabe der vorliegenden Erfindung ist es, bei einem Backofen nach dem Oberbegriff des Patentanspruches 1 die Reinigbarkeit zu erleichtern. The object of the present invention is in an oven according to the preamble of claim 1 to facilitate cleanability.

Erfindungsgemäß ist dies bei einem Backofen nach dem Oberbegriff des Patentanspruches dadurch erreicht, daß die Bodenwand als separates Teil ausgebildet ist sowie im Bodenbereich der Backofenmuffel oberhalb des zweiten Heizelementes gehaltert ist und dieses abdeckt. Die nach dem Pyrolysevorgang in der Backofenmuffel zurückbleibende Asche ist aus der Bodenwand in besonders einfacher Weise zu entfernen bzw. herauszuwischen. Die nachteiligen Ecken und Zwischenraumbereiche zwischen dem zweiten Heizkörper und der Bodenwand gemäß dem Stand der Technik entfallen erfindungsgemäß. Zudem ist durch die Abschirmung des zweiten Heizelementes durch die Bodenwand gegenüber dem Garraum ein größerer Temperaturunterschied zwischen der Bodenwand und den Seitenwänden bzw. der Deckwand der Muffel beim Pyrolysebetrieb einstellbar.This is according to the invention in an oven according to the preamble of the claim achieved in that the bottom wall is formed as a separate part and is held in the floor area of the oven muffle above the second heating element and covers this. The one remaining in the oven muffle after the pyrolysis process Ash can be removed from the bottom wall in a particularly simple manner or to wipe out. The adverse corners and spaces between the Second radiator and the bottom wall according to the prior art are omitted according to the invention. In addition, through the shielding of the second heating element Bottom wall compared to the cooking space a greater temperature difference between the Bottom wall and the side walls or the top wall of the muffle during pyrolysis adjustable.

Vorteilhafter Weise ist die Bodenwand etwa 0,5 mm stark. Durch die Ausbildung der Bodenwand als separates Teil ist es möglich, eine geringere Wandstärke als die der Backofenmuffel zu wählen, ein anderes Material zu verwenden oder das Bodenblech mit speziellen schmutzabweisenden Schichten zu versehen. Durch die geringe Wärmekapazität der Bodenwand wird der Leistungsbedarf beim Pyrolysebetrieb reduziert Weiterhin ist der Energiebedarf bei einem Garprozess, bei dem auch das zweite Heizelement eingeschaltet ist, im Vergleich zu stärkeren Bodenwanddicken herabgesetzt.The bottom wall is advantageously about 0.5 mm thick. By forming the bottom wall as a separate part, it is possible to have a smaller wall thickness than that of the oven muffle to choose to use a different material or to use the floor pan special dirt-repellent layers. Due to the low heat capacity the bottom wall, the power requirement in pyrolysis operation is further reduced is the energy requirement for a cooking process, which also includes the second heating element is switched on, reduced compared to thicker bottom wall thicknesses.

Gemäß einer bevorzugten Ausführungsform besitzt die Backofenmuffel einen geschlossenen Boden, ist oberhalb des Bodens das zweite Heizelement angeordnet, und ist oberhalb des zweiten Heizelementes die Bodenwand in Form eines insbesondere aus der Muffel herausnehmbaren Bodenbleches angeordnet. Der geschlossene Boden der Backofenmuffel garantiert sowohl einen vollständig dichten Abschluß des Garraumes nach unten als auch eine zusätzliche Wärmeisolation bezüglich der nach unten abgestrahlten Wärmestrahlung des zweiten Heizelementes. Ein herausnehmbares Bodenblech bietet zudem Vorteile bei der Reinigung des Backofens. Zur Verringerung der Wärmeverluste des Backofens ist das zweite Heizelement vom Boden der Backofenmuffel geringfügig beabstandet. Dem selben Zweck dient die Anordnung eines Reflektorelementes zwischen dem zweiten Heizelement und dem Boden der Backofenmuffel. In beiden Fällen wird das Aufheizen des Backofenmuffelbodens und das Weiterleiten der Wärme in die anderen Wände der Backofenmuffel deutlich verringert. Die thermische Ankopplung des zweiten Heizelementes an das Bodenblech bzw. an die Bodenwand kann dadurch verbessert werden, daß beide miteinander thermisch leitend verbunden sind. Vorteilhafterweise kann das Heizelement beispielsweise in Dickschichttechnik direkt auf dem Bodenblech realisiert sein.According to a preferred embodiment, the oven muffle has a closed one Floor, the second heating element is arranged above the floor, and is above the second heating element, the bottom wall in the form of a particular from the Muffle removable floor plate arranged. The closed bottom of the oven muffle guarantees that the cooking space is completely sealed bottom as well as additional thermal insulation with respect to the radiated down Heat radiation from the second heating element. A removable floor panel offers also advantages when cleaning the oven. To reduce heat loss of the oven, the second heating element from the bottom of the oven muffle is slight spaced. The arrangement of a reflector element between serves the same purpose the second heating element and the bottom of the oven muffle. In both cases Heating up the oven muffle base and transferring the heat to the others Walls of the oven muffle significantly reduced. The thermal coupling of the second Heating element on the floor panel or on the floor wall can be improved be that both are thermally conductively connected. Can advantageously the heating element is implemented directly on the floor panel using thick-film technology, for example his.

Um den Energiebedarf insbesondere beim Pyrolysebetrieb gering zu halten, ist die Bodenwand im wesentlichen über punkt- bzw. linienförmige Kontaktstellen in der Backofenmuffel gehaltert. Das Abfließen der in der Bodenwand bzw. im Bodenblech aufgenommenen Wärme in die Wände der Backofenmuffel kann durch diese Maßnahme deutlich reduziert werden.In order to keep the energy requirement low, especially in pyrolysis operation, the Bottom wall essentially via point or line-shaped contact points in the Oven muffle held. The drainage in the floor wall or in the floor panel Heat absorbed into the walls of the oven muffle can be avoided by this measure be significantly reduced.

Zur weiteren Verbesserung des Reinigungsverhaltens des Backofens ist vorteilhafter Weise vorgesehen, daß zumindest Teilbereiche der Seitenwände bzw. der Deckwand der Backofenmuffel eine katalytische Beschichtung aufweisen. Alternativ oder ergänzend kann auch vorgesehen sein, daß diese Bereiche der Muffelwand mit einer besonders leicht zu reinigenden Schicht beschichtet sind. Dies kann beispielsweise durch spezielle Email- oder Sol-Gel-Schichten realisiert sein.To further improve the cleaning behavior of the oven is more advantageous Provided that at least partial areas of the side walls or the top wall of the Oven muffle have a catalytic coating. Alternatively or in addition can also be provided that these areas of the muffle wall with a special easy to clean layer are coated. This can be done, for example, through special Enamel or sol-gel layers can be realized.

Nachfolgend sind anhand schematischer Darstellungen zwei Ausführungsbeispiele des erfindungsgemäßen Backofens beschrieben.Below are two exemplary embodiments of the described baking oven according to the invention.

Simplified in a sectional view essentially along the line II-II in Fig. 1 in an enlarged scale a portion of an oven according to the second embodiment.

Gemäß dem ersten Ausführungsbeispiel weist ein Backofen ein Gehäuse 1 auf, in dem eine einen Garraum begrenzende, quaderförmige Backofenmuffel 3 gehaltert ist (Fig. 1). Diese ist frontseitig offen und mit einer am Gehäuse 1 bzw. der Muffel 3 angelenkten Backofentür 5 verschließbar. Die Backofenmuffel 3 ist allseitig von einer Wärmeisolationsschicht 7 umgeben. Dabei ist die Menge des Isolationsmaterial bzw. die Anforderung an die Isolationseigenschaften der Wärmeisolationsschicht 7 aufgrund der im Pyrolysebetrieb auftretenden niedrigen Betriebstemperaturen, wie nachfolgend erläutert ist, im Vergleich zu herkömmlichen Backöfen mit außenliegendem Unterhitze-Heizkörper deutlich reduziert. Unterhalb der Decke der Backofenmuffel 3 ist ein Oberhitzeheizkörper 9 und oberhalb des Backofenbodens 12 ist mit Abstand zu diesem ein Unterhitzeheizkörper 11 gehaltert. Die Oberseite des Backofenbodens 12 ist mit einer die Wärmestrahlung des Unterhitzeheizkörpers 11 reflektierenden Metallschicht 13 bedeckt. Alternativ kann die reflektierende Eigenschaft auch durch ein in die Backofenmuffel 3 eingelegtes geeignetes Reflektorblech realisiert sein. Der Abstand zwischen dem Unterhitzeheizkörper 11 und dem Backofenboden 12 bzw. der Reflektorschicht 13 beträgt über deren gesamte Flächenausdehnung zumindest einige mm. Alternativ kann auch vorgesehen sein, daß der Backofenboden 12 über seine Fläche verteilt Prägungen aufweist, auf denen der Unterhitzeheizkörper 11 im wesentlichen punktförmig aufliegt.According to the first exemplary embodiment, an oven has a housing 1 in which a cuboid oven muffle 3 defining a cooking space is held (FIG. 1). This is open on the front and with one articulated on the housing 1 or the muffle 3 Oven door 5 lockable. The oven muffle 3 has a heat insulation layer on all sides 7 surrounded. Here is the amount of insulation material or the requirement to the insulation properties of the heat insulation layer 7 due to the pyrolysis operation occurring low operating temperatures, as explained below, in comparison compared to conventional ovens with an external bottom heat radiator reduced. Below the ceiling of the oven muffle 3 is an upper heat radiator 9 and Above the oven base 12 there is a lower heat radiator 11 at a distance from it supported. The top of the oven bottom 12 is the heat radiation of the Underheating radiator 11 reflective metal layer 13 covered. Alternatively, the reflective property also by a suitable inserted in the oven muffle 3 Reflector plate can be realized. The distance between the lower heat radiator 11 and the oven floor 12 or the reflector layer 13 is over their entire Area at least a few mm. Alternatively, it can also be provided that the oven base 12 has embossments distributed over its surface, on which the Lower heat radiator 11 rests essentially at a point.

Der Unterhitzeheizkörper 11 bzw. der Backofenboden 12 ist vollständig durch ein herausnehmbar in der Backofenmuffel 3 gehaltertes Bodenblech 15 bedeckt. Die Wandstärke des Bodenbleches 15 beträgt etwa 0,4 - 0,5 mm. Das Bodenblech 15 kann sowohl an der Innenseite der Backofentür 5 gehaltert sein, insbesondere wenn diese in Form eines an sich bekannten Backwagens ausgebildet ist, kann an den Seitenwänden oder der Rückwand der Backofenmuffel 3 in an sich bekannten Rillenbackrohren gehaltert sein oder in einem speziellen in der Backofenmuffel 3 vorgesehenen an sich bekannten Gargutträgergestell oder in den Muffelseitenwänden einhängbaren Führungsgittern gehaltert sein. Alternativ ist es auch möglich, das Bodenblech 15 nicht herausnehmbar an der Backofenmuffel 3 zu befestigen. Das Bodenblech 15 weist eine möglichst glatte Oberflächenkontur auf, um das Auswischen von Pyrolyserückständen zu erleichtern. Oberhalb des Bodenblechs 15 ist in verschiedenen Höhen ein Gargutträger 17 in der Backofenmuffel 3 halterbar.The bottom heat radiator 11 or the oven base 12 can be removed completely by a in the oven muffle 3 covered bottom plate 15 covered. The wall thickness the bottom plate 15 is about 0.4-0.5 mm. The bottom plate 15 can both on the Be held inside the oven door 5, especially if it is in the form of a known baking cart is formed, can on the side walls or the rear wall the oven muffle 3 can be held in known groove baking tubes or in a special provided in the oven muffle 3 known food support frame or be held in the muffle side walls of the guide grids. Alternatively, it is also possible for the base plate 15 not to be removable from the oven muffle 3 to attach. The bottom plate 15 has the smoothest possible surface contour to make it easier to wipe out pyrolysis residues. Above the floor panel 15, a food support 17 can be held in the oven muffle 3 at different heights.

Zum Betrieb des Backofens kann mittels einer Bedieneinheit 19 einer Steuereinheit 21 ein Pyrolysebetrieb- oder Garbetriebwunsch mitgeteilt werden. Dazu sind die Bedieneinheit 19, die Steuereinheit 21, die Heizkörper 9, 11 und weitere an sich bekannte Funktionselemente von Backöfen, wie beispielsweise ein Garraum-Temperaturfühler, über Verbindungsleitungen 23 verbunden. Im Garbetrieb ist der Unterhitzeheizkörper 11 durch das dünne Bodenblech 15 vom Gargut abgeschirmt. Das Ausmaß der thermischen Abschirmung ist jedoch geringer als im Falle der an sich bekannten Anordnung eines Unterhitzeheizkörpers außerhalb der Backofenmuffel 3 unterhalb des Backofenbodens 12. A control unit 21 can be used to operate the oven by means of an operating unit 19 Pyrolysis or cooking mode request can be communicated. For this are the control unit 19, the control unit 21, the radiators 9, 11 and other functional elements known per se ovens, such as a cooking space temperature sensor, via connecting lines 23 connected. In cooking mode, the lower heat radiator 11 is due to the thin bottom plate 15 shielded from the food. The extent of thermal shielding is, however, less than in the case of the known arrangement of a bottom heat radiator outside the oven muffle 3 below the oven base 12.

Durch die Reflektionsschicht 13 und die thermisch möglichst schwache Ankopplung des Bodenbleches 15 an die Backofenmuffel 3 ist die Energiebilanz bei der Gestaltung des Backofens gemäß dem ersten Ausführungsbeispiel deshalb vergleichsweise günstiger. Im Pyrolysebetrieb schaltet die Steuereinheit 21 den Oberhitzeheizkörper 9 ab und betreibt den Unterhitzeheizkörper 11 mit voller Leistung. Daraus ergibt sich eine Aufheizung des Bodenbleches 15 auf etwa 500°C, während die Backofenschwerpunktstemperatur geringer als 350°C bleibt. Der primäre Verschmutzungsbereich der Backofenmuffel 3, nämlich das Bodenblech 15, wird dabei pyrolytisch gereinigt. Infolge der geringen thermischen Masse des Bodenbleches 15, der schlechten thermischen Ankopplung an die Wände der Backofenmuffel 3 bzw. der Anordnung der Reflektorschicht 13 wird dabei elektrische Energie gespart. Hinzu kommt, daß aufgrund der geringen Schwerpunktstemperatur in der Backofenmuffel 3 Maßnahmen zur an sich bekannten Türverriegelung im Pyrolysebetrieb im Sinne der Sicherheitsvorschriften nicht mehr erforderlich sind. Um das Reinigungsergebnis bzgl. der übrigen Wände der Backofenmuffel 3 sicherstellen zu können, sind diese mit einer katalytischen Reinigungsschicht 25 bedeckt.Due to the reflection layer 13 and the thermally weakest possible coupling of the Floor plate 15 to the oven muffle 3 is the energy balance in the design of the Oven according to the first embodiment is therefore comparatively cheaper. In pyrolysis mode, the control unit 21 switches the top heat radiator 9 off and operates it the bottom heat radiator 11 at full power. This results in heating the bottom plate 15 to about 500 ° C, while the oven's center of gravity remains below 350 ° C. The primary contamination area of the oven muffle 3, namely the bottom plate 15 is cleaned pyrolytically. Due to the low thermal Mass of the bottom plate 15, the poor thermal coupling to the Walls of the oven muffle 3 or the arrangement of the reflector layer 13 is thereby electrical energy saved. In addition, due to the low center of gravity temperature in the oven muffle 3 measures for the known door locking in Pyrolysis operation in the sense of the safety regulations are no longer required. To do that Ensure the cleaning result with regard to the remaining walls of the oven muffle 3 can, they are covered with a catalytic cleaning layer 25.

Gemäß den in Fig. 2 gezeigten vom ersten Ausführungsbeispiel abweichenden Details eines Backofens nach dem zweiten Ausführungsbeispiel ist das wannenförmig ausgebildete Bodenblech 15 an seiner Unterseite mit einem als Unterhitzeheizkörper 11 dienenden Rohrheizkörper versehen. Dieser ist über nicht näher gezeigte Steckverbindungen im Bereich der Rückwand der Backofenmuffel 3 elektrisch kontaktierbar. Falls diese Steckverbindung ausreichend stabil gestaltet ist, kann sie zur alleinigen Halterung des Unterhitzekörpers in der Backofenmuffel verwendet werden. In in den Seitenwänden der Backofenmuffel 3 ausgebildeten horizontal verlaufenden Führungsrillen 31 ist gemäß Fig. 2 das Bodenblech 15 einschiebbar mit Abstand von der Reflektorschicht 13 stabil gehaltert. Dabei ruht der Endabschnitt eines ungebördelten Seitenwandbereiches 33 des Bodenbleches 15 linienförmig auf einer Führungsfläche der Rille 31. Die Steuereinheit 21 detektiert die Anwesenheit des Unterhitzeheizkörpers 11 bzw. dessen ohmschen Widerstandes und damit des Bodenbleches 15 in der Backofenmuffel 3. Ein Gar- oder Pyrolysebetrieb ist erst möglich, wenn die Steuereinheit 21 das Vorhandensein des Bodenbleches 15 feststellt. Infolge der Abschirmung des Unterhitzeheizkörpers 11 durch das dünne und thermisch schwach an die Backofenmuffelwände angekoppelte Bodenblech 15 können auf besonders einfache Weise große Temperaturunterschiede zwischen dem Primärverschmutzungsbereich - das Bodenblech - und den Sekundärverschmutzungsbereichen - die Deck- und Seitenwände - eingestellt werden. Zudem führt insbesondere die gezielt schwache thermische Ankopplung des Bodenbleches 15 an die Wände der Backofenmuffel 3 einen geringen Energieverbrauch beim Pyrolysebetrieb. Während des Pyrolysebetriebes bleibt ein nicht näher dargestelltes Umluftgebläse im wesentlichen abgeschaltet.According to the details shown in FIG. 2 that differ from the first exemplary embodiment a baking oven according to the second embodiment is trough-shaped Base plate 15 on its underside with a serving as a bottom heat radiator 11 Provide tubular heater. This is via plug connections not shown in the Area of the rear wall of the oven muffle 3 electrically contactable. If this connector is designed to be sufficiently stable, it can be used to hold the lower heat body alone be used in the oven muffle. In the side walls of the oven muffle 3 formed horizontal guide grooves 31 is shown in FIG. 2 the bottom plate 15 can be inserted stably at a distance from the reflector layer 13. The end section of an unflared side wall region 33 of the base plate rests 15 linearly on a guide surface of the groove 31. The control unit 21 detects the presence of the lower heat radiator 11 or its ohmic resistance and thus the bottom plate 15 in the oven muffle 3. A cooking or pyrolysis operation only possible when the control unit 21 determines the presence of the floor plate 15. Due to the shielding of the lower heat radiator 11 by the thin and thermal bottom plate 15 weakly coupled to the oven muffle walls can large temperature differences between the primary pollution area in a particularly simple manner - The floor panel - and the secondary pollution areas - the Top and side walls - can be adjusted. In addition, the leads in particular weak thermal coupling of the bottom plate 15 to the walls of the oven muffle 3 low energy consumption in pyrolysis operation. During pyrolysis operation a circulating air fan, not shown, remains essentially switched off.
