Description

Die Erfindung bezieht sich auf einen Backofen gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to an oven according to the preamble of claim 1.

Bei einem bekannten Umluftofen dieser Art (DE-AS 25 57 867) ist ein Lüfterrad eines Umluftgebläses in einer durch eine Abdeckwand einerseits und durch die Rückwand des Garraumes andererseits gebildeten Gebläsekammer angeordnet und beidseitig der Abdeckwand in Nähe der Seitenwände des Garraumes befinden sich langgestreckte, vertikale Ausblasschlitze, denen unmittelbar benachbart wesentlich schmälere, weitere Ausblasschlitze zugeordnet sind. Um eine Turbulenz der ausgeblasenen Luftströmung zu bewirken sind an den erstgenannten Ausblasschlitzen als auch an besonderem Luftleitelementen im Inneren der Gebläsekammer in den Strömungsweg ragende Kanten bzw. Abbiegungen vorgesehen. Durch die zweitgenannten schmalen Schlitze wird die Turbulenz der ausströmenden Luft noch vergrößert.In a known convection oven of this type (DE-AS 25 57 867), a fan wheel of a convection fan is arranged in a blower chamber formed by a cover wall on the one hand and by the rear wall of the cooking space on the other hand, and on both sides of the cover wall near the side walls of the cooking space there are elongated, vertical Blow-out slots, to which substantially narrower, further blow-out slots are assigned immediately adjacent. In order to cause turbulence of the blown-out air flow, edges or bends projecting into the flow path are provided on the first-mentioned blowout slots as well as on special air guiding elements in the interior of the blower chamber. The turbulence of the outflowing air is further increased by the second-mentioned narrow slots.

Der Erfindung liegt nun die Aufgabe zugrunde, bei einem Backofen der im Oberbegriff des Patentanspruches 1 genannten Art die Strömung der durch die Ausblasschlitze ausgeblasenen Luft in bezug auf das im Garraum, insb. im Mittelbereich des Garraumes befindliche Gargut ohne zusätzliche, aufwendige Luftleitelemente zu verbessern. Daneben soll die Ausgestaltung für die Garung mittels Mikrowellenenergie geeignet sein.The invention is based on the object, in a baking oven of the type mentioned in the preamble of claim 1, the flow of the air blown out through the exhaust slots in relation to the food to be found in the cooking space, in particular in the central region of the cooking space, without additional, expensive To improve air control elements. In addition, the design should be suitable for cooking using microwave energy.

Diese Aufgabe wird erfindungsgemäß gelöst durch die im Kennzeichnungsteil des Patentanspruches 1 aufgeführten Maßnahmen. Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Patentansprüchen.This object is achieved by the measures listed in the characterizing part of claim 1. Further developments of the invention result from the following patent claims.

Aufgrund der erfindungsgemäßen Ausgestaltung der Ausblasschlitze erhält man auf einfache Weise die Möglichkeit, durch entsprechende Bemessung und Anzahl der Stege und Schlitzabschnitte Einfluß zu nehmen auf die Strömungsverhältnisse an den gegenüberliegenden Ausblasschlitzen in Abhängigkeit von der Drehrichtung des Umluftgebläses. Insbesondere kann man auf diese Weise eine Vergleichmäßigung der Luftströmung und eine Verbesserung der Luftströmung insb. im mittleren Bereich des Backofens erhalten. Dabei erübrigen sich zusätzliche Luftleitbleche oder dergleichen im Inneren der Gebläsekammer. Darüber hinaus wird bei Vorhandensein eines Mikrowellengenerators durch die besondere Ausgestaltung der Ausblasschlitze eine Mikrowellendichtheit der Gebläsekammer erreicht, wobei die aufeinanderfolgenden, durch Stege voneinander getrennte Schlitzabschnitte relativ groß sein können, wenn die Ausblasschlitze den angrenzenden Garraumwänden zugewandt sind, d.h. sich in seitlichen Bereich der Abdeckwand befinden.Due to the configuration of the blow-out slots according to the invention, the possibility is given to influence the flow conditions at the opposite blow-out slots depending on the direction of rotation of the circulating air fan by appropriate dimensioning and number of webs and slot sections. In this way, in particular, the air flow can be made more uniform and the air flow improved, particularly in the central region of the oven. This eliminates the need for additional air baffles or the like inside the blower chamber. In addition, in the presence of a microwave generator, the special design of the blow-out slots achieves microwave tightness of the blower chamber, the successive slot sections separated by webs being able to be relatively large if the blow-out slots face the adjacent cooking space walls, i.e. are located in the side area of the cover wall.

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.

It shows:
Fig. 1

two different, perspective views of the cover wall of the oven according to FIG. 1.

Beim Ausführungsbeispiel wird ein Garraum 1 begrenzt durch eine quaderförmige Ofenmuffel 2, die durch eine nicht-dargestellte Ofentür verschließbar ist. Unmittelbar unterhalb der oberen Garraumwand 3 befindet sich ein Strahlungsheizkörper 4. Unterhalb der unteren Garraumwand 5 ist ein die Unterhitze des Backofens bildender Heizkörper 6 angeordnet. An den gegenüberliegenden Garraum-Seitenwänden 7 und 8 sind z.B. in zwei unterschiedlichen Höhenlagen rippenartige Stützen 9 befestigt, auf denen z.B. zwei rost- oder pfannenartige Gargutträger 10 bzw. Backbleche mit Tragrahmen gelagert sein können. Unmittelbar vor der hinteren Garraumwand 11 befindet sich eine wannenartige Abdeckwand 12, die zu einem Teil den Garraum 1 nach hinten hin begrenzt und zwischen der hinteren Garraumwand und dieser Abdeckwand 12 eine Gebläsekammer 13 bildet. Die Abdeckwand 12 besteht aus einem im wesentlichen ebenen Wannenboden 14, aus im wesentlichen rechtwinkelig abgebogenen seitlichen und flächigen Wannenrändern z.B. 15 und 16 (Fig. 2, 3) sowie aus Wannenflanschen z.B. 17, 18, die zusammenhängen und parallel zum Wannenboden 14 verlaufen und flächig bzw. bündig an der hinteren Garraumwand 11 anliegen. Wie aus Fig. 1 ersichtlich, überdeckt die Abdeckwand 12 im wesentlichen die gesamte hintere Garraumwand 11. Im Wannenboden 14, und zwar außermittig im oberen Bereich des Wannenboden 14, befindet sich eine runde Aßsaugöffnung 19 für die Umluft, gebildet gemäß Fig. 2 und 3 durch eine runde perforierte Fläche.In the exemplary embodiment, a cooking space 1 is delimited by a cuboid oven muffle 2, which can be closed by an oven door (not shown). A radiant heater 4 is located directly below the upper cooking chamber wall 3. A heating element 6 forming the bottom heat of the oven is arranged below the lower cooking chamber wall 5. On the opposite cooking chamber side walls 7 and 8, rib-like supports 9 are fastened, for example, at two different heights, on which, for example, two rust-like or pan-like food supports 10 or baking trays with a supporting frame can be mounted. Immediately in front of the rear cooking chamber wall 11 is a trough-like cover wall 12, which partially limits the cooking chamber 1 towards the rear and forms a blower chamber 13 between the rear cooking chamber wall and this cover wall 12. The cover wall 12 consists of an essentially flat trough base 14, from substantially rectangular side and flat trough edges, for example 15 and 16 (FIGS. 2, 3), and from trough flanges, for example 17, 18, which are connected and run parallel to the trough base 14 and are flat or rest flush against the rear wall 11 of the cooking space. As can be seen from FIG. 1, the cover wall 12 essentially covers the entire rear cooking chamber wall 11. In the pan floor 14, specifically off-center in the upper region of the pan floor 14, there is a round suction suction opening 19 for the circulating air, formed according to FIGS. 2 and 3 through a round perforated surface.

Hinter dieser Ansaugöffnung 19 im Inneren der Gebläsekammer 13 befindet sich das Lüfterrad 20 eines nicht weiter dargestellten Umluftgebläses, dessen Drehrichtung durch einen Pfeil verdeutlicht ist. In den vertikalen, gegenüberliegenden seitlichen Wannenrändern 15, 16 befinden sich langgestreckte Ausblasschlitze 21, 22, die in Abhängigkeit von der Drehrichtung des Lüfterrades 20 in unterschiedlicher Höhe angeordnet sind, derart, daß der Ausblasschlitz 21 infolge des nach unten gerichteten Teilluftstromes höher liegt als der Ausblasschlitz 22 für die nach oben gerichtete Luftsteuerungskomponente (Fig. 1). Wie insb. Fig. 2 und 3 zeigen, bestehen die Ausblasschlitze 21 und 22 aus aufeinanderfolgenden Schlitzabschnitten 21a bzw. 22a, die durch schmale Stege 21b bzw. 22b voneinander getrennt sind. Hierbei sind die Stege der metallischen Abdeckwand 12 mit den gegenüberliegenden Schlitz-Längskanten der Ausblasschlitze 21, 22 metallisch verbunden und wirken im Mikrowellenfalle als Kurzschlußstege, die einen Mikrowellenaustritt vom Ofenraum 1 her in die Gebläsekammer 13 verhindern. Diese Ausblasschlitze 21, 22 liegen den angrenzenden, seitlichen Garraumwänden 7 und 8 gegenüber, so daß die aus den Ausblasschlitzen austretende, in wesentlichen laminare Luftströmung unmittelbar auf diese seitlichen Garraumwände auftrifft und dort in das Innere des Garraumes 1 reflektiert und verwirbelt wird, wie durch Strömungspfeile in Fig. 1 verdeutlicht. In Abhängigkeit von der Beschaffenheit des Garraumes, der Anordnung der Heizkörper und der Backbleche usw. kann die Ausblasschlitze 21, 22 bzw. die Anzahl und Größe der Schlitzabschnitte und der Stege variiert werden. Selbstverständlich besteht im Rahmen der vorliegenden Erfindung auch die Möglichkeit, Ausblasschlitze an anderen Stellen der Abdeckwand vorzusehen bzw. zusätzlich zu den im Ausführungsbeispiel gezeigten Ausblasschlitzen weitere Ausblasschlitze vorzusehen, die z.B. eine Strömung in Richtung des oberen Heizkörpers oder eines Temperaturfühlers bewirken.Behind this suction opening 19 in the interior of the blower chamber 13 is the fan wheel 20 of a circulating air blower, not shown, the direction of rotation of which is illustrated by an arrow. In the vertical, opposite side trough edges 15, 16 there are elongated blow-out slots 21, 22, which are arranged at different heights depending on the direction of rotation of the fan wheel 20, such that the blow-out slot 21 is higher than the blow-out slot due to the downward-directed partial air flow 22 for the upward air control component (Fig. 1). As shown in FIGS. 2 and 3 in particular, the blow-out slots 21 and 22 consist of successive slot sections 21a and 22a which are separated from one another by narrow webs 21b and 22b. Here, the webs of the metallic cover wall 12 are metallically connected to the opposite slot longitudinal edges of the blow-out slots 21, 22 and act in the microwave case as short-circuit bars, which prevent microwave leakage from the oven chamber 1 into the blower chamber 13. These blow-out slots 21, 22 lie opposite the adjacent side cooking chamber walls 7 and 8, so that the essentially laminar air flow emerging from the blow-out slots hits these side cooking chamber walls directly and is reflected and swirled into the interior of the cooking chamber 1, as by flow arrows illustrated in Fig. 1. Depending on the nature of the cooking space, the arrangement of the radiators and the baking trays, etc., the blow-out slots 21, 22 or the number and size of the slot sections and the webs can be varied. Of course, within the scope of the present invention there is also the possibility of providing blow-out slots at other locations on the cover wall or, in addition to the blow-out slots shown in the exemplary embodiment, further blow-out slots to provide, for example, a flow in the direction of the upper radiator or a temperature sensor.
