Description

Die Erfindung bezieht sich auf eine Backvorrichtung, der im Oberbegriff des Anspruches näher bezeichneten Art.The invention relates to a Baking device, which in the preamble of Claim specified type.

Im gewerblichen Großküchenbereich sowie im Haushaltsbereich werden derzeit Backöfen als Umluftbacköfen eingesetzt, bei denen in dem eigentlichen Backraum mehrere Backlagen eingerichtet sind. So bei dem einfachen Backofen eine Backlage und bei dem Umluftbackofen drei bis vier Backlagen, bei entsprechender Heißluftverteilung unterhalb und oberhalb der einzelnen Backlagen.In the commercial canteen area as well as in Household are currently used as ovens Forced convection ovens used in which actual baking room several baking layers are set up. So with the simple one Oven a baking layer and in the convection oven three to four baking layers, at corresponding hot air distribution below and above the individual baking layers.

Dabei wird die Heißluft in der Regel durch Gasbrenner erzeugt, wobei ein Ventilator die so erzeugte Heißluft in dem eigentlichen Backraum verwirbelt. Problematisch hierbei ist die optimale gleichmäßige Heißluftverteilung entsprechend den einzelnen Backlagen.The hot air is usually through Gas burner generated, with a fan hot air generated in the actual Baking room swirled. The problem here is the optimal even distribution of hot air according to the individual baking layers.

Des weiteren sind die herkömmlichen Umluftbacköfen nur als solche einzusetzen und nicht als normaler Backofen mit einer oder maximal zwei Backlagen ohne Umlufterzeugung im Backraum, ausgenommen elektrisch beheizte Backöfen. Furthermore, the conventional convection ovens only used as such and not as a normal oven with one or maximum two baking layers without air circulation in the Baking room, except electrically heated Ovens.

Der Erfindung liegt die Aufgabe zugrunde, eine Backofenvorrichtung zu schaffen, die mit Gas betrieben werden kann, bei gleichzeitiger Umlufterzeugung im Backofen selbst und optimaler Heißluftverteilung entsprechend der einzelnen Backlagen. Ferner soll die gleiche Backofenvorrichtung auch als einfacher Backofen genutzt werden, bei Ausschalten der Umlufterzeugung.The invention has for its object a To create oven device with gas can be operated at the same time Air circulation in the oven itself and optimal hot air distribution according to the individual baking layers. Furthermore, the same is said Oven device also as a simple oven be used when the Convection generation.

Derzeit sind keine Gas-Umluftbacköfen bekannt, die kombiniert genutzt werden können, sei es als Umluftbackofen oder als normaler Backofen bei optimaler Heißluftverteilung.There are currently no gas convection ovens known that can be used in combination, be it as a convection oven or as a normal oven with optimal hot air distribution.

EP 0 115 838 A2 zeigt eine Kombi-Gas-Backofenvorrichtung, bei der das Bodenblech unmittelbar an die Wände des Backraums anschließt. Die Heißluft von dem Gasbrenner wird durch einen Gaskanal im Bereich der Rückwand des Backraums ein ganzes Stück über das Niveau des Bodenblechs bis knapp unter die Ventilatoreintrittsöffnung geführt, wodurch bei Betrieb ohne Umluftströmung ein erheblicher Teil des Volumens des Backraums nicht mit Heißluft direkt beaufschlagt wird.EP 0 115 838 A2 shows a combination gas oven device in which the floor pan connects directly to the walls of the baking chamber. The Hot air from the gas burner is passed through a gas duct in the area The back wall of the baking chamber is quite a bit above the level of the base plate to just under the fan inlet opening, which makes Operation without recirculation is a significant part of the volume of the Baking chamber is not directly exposed to hot air.

Die Aufgabe wird erfindungsgemäß durch die Ansprüche 1 bis 6 gelöst.The object is achieved by the Claims 1 to 6 solved.

Die Erfindung beruht auf der Überlegung, durch eine spezielle Anordnung von Luftleitelementen (6, 7, 8, 10) im Backraum selbst eine optimal gezielte Luftströmung (9, 11) zu gewährleisten, wonach sämtliche Backlagen (3) in dem Backofen an jeder Stelle gleichmäßig beheizt werden. Die Luftleitelemente (6, 10) sind an der Backofenrückwand und an der Backofenkopfwand (7, 8) angebracht, wobei die Heißlufterzeugung durch einen Gasröhrenbrenner (1) geschieht, der unterhalb des Bodenbleches (2) angebracht ist. Das Bodenblech (2) selbst enthält zu den Seitenblechen hin einen Luftschlitz von ca. 1,5 cm auf jeder Seite.The invention is based on the consideration a special arrangement of air guiding elements (6, 7, 8, 10) in the baking room itself is optimal to ensure targeted air flow (9, 11), after which all baking layers (3) in the The oven is evenly heated at every point become. The air guiding elements (6, 10) are on the Oven rear wall and on the oven head wall (7, 8) attached, the hot air generation through a gas tube burner (1), attached below the floor plate (2) is. The bottom plate (2) itself contains the Side panels an air slot of approx. 1.5 cm on each side.

Dadurch dringt die Heißluft zunächst in den Backofen, wobei die Heißluft dann durch einen Ventilator (5), der in das hintere Luftleitelement (7, 10) integriert ist, angesaugt und gleichzeitig wieder verwirbelt wird. Die Heißluftverwirbelung geschieht dadurch, in dem As a result, the hot air first penetrates the Oven, the hot air then through a Fan (5) in the rear air guide (7, 10) is integrated, sucked and is swirled again at the same time. The Hot air swirling happens in that

der Ventilator (5) Heißluft ansaugt und gleichzeitig durch die Heißluftöffnungen (10) wieder abgibt, wodurch eine horizontale Luftströmung entsteht (11), die sich schichtenweise zu den einzelnen Backlagen aufbaut. Gleichzeitig drückt der Ventilator (5) die angesaugte Luft durch eine schmale Öffnung in das Kaminblech (7), wodurch in dem Kaminabluftblech (7) eine Sogwirkung entsteht und somit Abluft durch die Kaminlöcher in den Kamin nach außen dringt, ohne daß hierdurch ein nennenswerter Heißluftwärmeverlust entsteht.the fan (5) draws in hot air and simultaneously through the hot air openings (10) releases again, creating a horizontal air flow arises (11), which is layered builds up to the individual baking layers. At the same time, the fan (5) presses the sucked in air through a narrow opening in the chimney plate (7), whereby in the chimney exhaust plate (7) a suction effect arises and thus exhaust air through the chimney holes in the Chimney penetrates to the outside without this a significant loss of hot air heat arises.

Durch Ausschalten des Ventilators (5) im hinteren Luftleitelement erfüllt der Backofen die Funktion eines normalen Backofens, ohne Umluftwirkung und damit vermindertem Heizbedarf bei Backvorgängen in einer oder maximal zwei Lagen, so daß die Backvorrichtung je nach Backbedarf energiesparend genutzt werden kann.By switching off the fan (5) in the the oven meets the rear air control element the function of a normal oven without Circulating air effect and thus reduced heating requirements for baking processes in one or maximum two layers, so that the baking device depending on Baking needs can be used to save energy can.
