Ein derartiger Backofen ist bekannt aus der Druckschrift DE 93 09 989 U1 , wobei die Mündungsöffnung des Wrasenkanals im Randbereich des Abluftkanals im Strömungsweg der Abluft so angeordnet ist, daß ein laminarer Strömungsverlauf der Abluft und eine laminare Einleitung des Wrasenstroms in die Abluft bewirkt wird. Der feuchte Wrasen wird also von der Abluft eingehüllt und im Randbereich der frontseitigen Ausblasöffnung des Abluftkanals nach außen abgeführt.Such an oven is known from the document DE 93 09 989 U1 , Wherein the mouth opening of the Wrasenkanals in the edge region of the exhaust duct in the flow path of the exhaust air is arranged so that a laminar flow pattern of the exhaust air and a laminar introduction of the Wrasenstroms is effected in the exhaust air. The moist vapor is thus enveloped by the exhaust air and discharged in the edge region of the front exhaust opening of the exhaust duct to the outside.

DE 42 11 755 A1 beschreibt einen Back- und Bratofen mit einer Ofenmuffel, die in ihrer deckseitigen Muffelwand eine Wrasenabzugsöffnung aufweist, und zwar mit einem Kühlluftgebläse und einer oberhalb der Ofenmuffel angeordneten, zur Ofenfrontseite führenden Kühlabluft- und Wrasenabzugseinrichtung, in der der in der Ofenmuffel entstehende Wrasen einmündet, wobei die Kühlabluft- und Wrasenabzugseinrichtung in ein Spiralgehäusebereich und in ein zur Ofenfrontseite hin führenden trichterförmigen Diffusorgehäusebereich aufgeteilt ist, wobei im Spiralgehäusebereich das Kühlluftgebläse angeordnet sowie die Eintrittsöffnung für die erwärmte Kühlluft ausgebildet ist und im Diffusorgehäusebereich die Einmündungsstelle für den aus der Ofenmuffel abzuführenden Wrasen gelegt ist. Dadurch sollen Kühlluft- und Wrasenabzugssysteme für verringerte Komplexität und Kosten kombiniert werden. DE 42 11 755 A1 describes a baking and roasting oven with a furnace muffle, which has a Wrasenabzugsöffnung in its top-side muffle wall, with a cooling air blower and arranged above the furnace muffle, leading to the furnace front Kühlabuft- and Wrasenabzugseinrichtung in which the resulting in the furnace muff fumes, wherein the Kühlabluft- and Wrasenabzugseinrichtung is divided into a spiral housing portion and leading to the furnace front side funnel-shaped diffuser housing area, wherein arranged in the spiral housing area the cooling air blower and the inlet opening for the heated cooling air is formed in the diffuser housing area and the point of confluence for the discharged from the oven muffle Wrasen. This will combine cooling air and vapor extraction systems for reduced complexity and cost.

Aufgabe der vorliegenden Erfindung ist es, bei einem Backofen nach dem Oberbegriff des Patentanspruches 1 die Verteilung des ausgeblasenen Wrasens zu verbessern.Object of the present invention is to improve the distribution of blown Wrasens in an oven according to the preamble of claim 1.

Erfindungsgemäß ist dies bei einem gattungsgemäßen Backofen durch die technischen Merkmale im kennzeichenden Teil von Anspruch 1 erreicht. Infolge der Längenerstreckung des Wrasenkanal-Anschlußstückes kann der Wrasen besser über die Breite des Abluftkanals sowie gezielter verteilt werden. Dies ist insbesondere durch die Verwendung des zusätzlichen Wrasengebläses gleichmäßig und mit ausreichendem Druck möglich. Durch das Wrasengebläse ist ausgeschlossen, daß der Wrasen infolge des von dem Kühlluftgebläse geförderten Kühlluft-Hauptstromes zurück in die Ofenmuffel gedrückt wird. Die Bodenplatte des Abluftkanals weist im Bereich des Wrasenkanal-Anschlußstückes eine Vertiefung zur Vergrößerung des freien Strömungsquerschnittes des Wrasenkanal-Anschlußstückes auf.According to the invention this is achieved in a generic oven by the technical features in the characterizing part of claim 1. Due to the length extension of the Wrasenkanal fitting, the vapor can be better distributed over the width of the exhaust duct and targeted. This is possible in particular by the use of the additional steam blower evenly and with sufficient pressure. Through the steam blower is excluded that the vapor is forced back into the oven muffle as a result of the promoted by the cooling air blower cooling air main stream. The bottom plate of the exhaust duct has in the region of the Wrasenkanal fitting a recess for increasing the free flow cross-section of the Wrasenkanal fitting.

Vorteilhafterweise ist das Wrasenkanal-Anschlußstück zur Vergrößerung des freien Strömungsquerschnittes des Abluftkanals im Bereich des Anschlußstückes tiefergelegt im Abluftkanal angeordnet. Das Wrasenkanal-Anschlußstück wirkt bezüglich der Abluftströmung kaum als nachteilige Strömungsbarriere.Advantageously, the Wrasenkanal connector is set to increase the free flow cross-section of the exhaust duct in the region of the connector lowered in the exhaust duct. The Wrasenkanal fitting hardly affects with respect to the exhaust air flow as an adverse flow barrier.

Gemäß einer bevorzugten Ausführungsform ist das Wrasengebläse etwa in der Höhe der Bodenplatte des Abluftkanals oder darüber angeordnet. Dadurch ist bei geringer Bauhöhe, also einer möglichst gering von der Oberseite der Muffel beabstandeten Anordnung des Abluftkanals, das Wrasengebläse bzw. der Gebläsemotor trotzdem ausreichend beabstandet oberhalb der heißen Muffel angeordnet.According to a preferred embodiment, the steam blower is arranged approximately in the height of the bottom plate of the exhaust duct or above. As a result, with a low overall height, that is to say the arrangement of the exhaust air duct which is as small as possible from the upper side of the muffle, the steam blower or the blower motor nevertheless is arranged at a sufficient distance above the hot muffle.

Zur Verbesserung der Verteilung des Wrasens in der Abluft weist das Wrasenkanal-Anschlußstück zumindest zwei voneinander beabstandet angeordnete Wrasenausblasöffnungen auf.To improve the distribution of Wrasens in the exhaust air, the Wrasenkanal fitting has at least two spaced apart Wrasenausblasöffnungen.

Nachfolgend ist anhand schematischer Darstellung ein Ausführungsbeispiel des erfindungsgemäßen Backofens beschrieben. Es zeigen:

Ein Backofen 1 weist ein an sich bekanntes Ofengehäuse 3 (in Fig. 1, 2 aus Vereinfachungsgründen nicht gezeigt) auf, das eine quaderförmige frontseitig offene Ofenmuffel 5 umgibt. Zur Erwärmung der Ofenmuffel 5 bzw. des Garraums sind diesem nicht näher gezeigte und von einer Steuereinheit des Backofens 1 gesteuerte Heizelemente in an sich bekannter Weise zugeordnet. Die Ofenmuffel 5 ist umfangseitig mit einer geeigneten thermischen Muffelisolation 7 versehen. Ein an sich bekannter, sich trichterförmig nach vorne erweiternder, front- und rückseitig offener Abluftkanal 9 ist durch eine unmittelbar auf der deckseitigen Muffelisolation 7 angeordnete metallische Bodenplatte 11 und eine darauf gesetzte an sich bekannte Deckhaube 13 aus Kunststoff gebildet (in Fig. 1, 2 nicht gezeigt sowie aus Vereinfachungsgründen in Fig. 3 lediglich abschnittsweise gezeigt). Die Deckhaube 13 weist eine als Deckwand des Abluftkanals 9 dienende Grundplatte auf sowie beidseits von der Grundplatte rechtwinkelig abstehende als Seitenwände des Abluftkanals dienende Seitenwände. Über nicht näher gezeigte Öffnungen des Ofengehäuses 3 saugt ein an die rückseitige Öffnung des Abluftkanales 9 angeschlossenes Kühlluftgebläse 15 Kühlluft in an sich bekannter Weise in das Ofengehäuse 3. Das Kühlluftgebläse 15 drückt nach dem Kühlen geeigneter Komponenten, z.B. der Elektronik, bzw. Stellen des Backofens 1 die dabei erwärmte Kühlluft in den Abluftkanal 9 der frontseitig in geeigneten Kühlluftfrontöffnungen 17 des Backofens 1 endet.An oven 1 has a known per se oven housing 3 (in Fig. 1, 2 not shown for reasons of simplification), which is a cuboid front open oven muffle 5 surrounds. For heating the oven muffle 5 and the cooking chamber this not shown in detail and controlled by a control unit of the oven 1 heating elements are assigned in a conventional manner. The oven muffle 5 is peripherally provided with a suitable thermal muffle insulation 7. A per se known, funnel-shaped forward expanding, front and rear open exhaust duct 9 is formed by a directly on the top side muffle insulation 7 arranged metallic bottom plate 11 and a set thereon known cover hood 13 made of plastic (in Fig. 1, 2 not shown and for reasons of simplicity in Fig. 3 only shown in sections). The cover hood 13 has a base plate serving as a cover wall of the exhaust duct 9 and on both sides of the base plate at right angles protruding side walls of the exhaust duct side walls. About not shown in detail openings of the furnace housing 3 sucks a connected to the rear opening of the exhaust duct 9 cooling air fan 15 cooling air in a conventional manner in the furnace housing 3. The cooling fan 15 presses after cooling suitable components, such as electronics, or bodies of the oven 1, the cooling air thereby heated ends in the exhaust duct 9 of the front side in suitable cooling air front openings 17 of the oven 1.

Der Garraum ist zum Abführen von beim Garvorgang entstehendem Wrasen über einen schlauch- oder rohrförmigen Wrasenkanal 19 mit einem auf der deckseitigen Muffelisolation 7 bzw. der Bodenplatte 11 des Abluftkanals 9 angeordneten Spiralgehäuse 21 verbunden. Im inneren des Spiralgehäuses 21 ist ein Lüfterrad eines Wrasengebläses 22 gehaltert. Auf dem Spiralgehäuse 21 sitzt der das Lüfterrad antreibende Lüftermotor 41. Das Wrasengebläse 22 zieht bei Bedarf, gesteuert von der Steuereinheit des Backofens 1, den heißen Wrasen aus der Ofenmuffel 5 durch den Wrasenkanal 19 in das Spiralgehäuse 21 und drückt den Wrasen aus einer im Randbereich des Abluftkanals 9 vorgesehenen Wraseneinblasöffnung 23 des Spiralgehäuses 21. Alternativ kann der Wrasenlüfter auch im Wrasenkanal angeordnet sein und auf das Spiralgehäuse verzichtet werden, wenn sich der Wrasenkanal mit einer Wraseneinblasöffnung bis in den Randbereich des Abluftkanals 9 erstreckt.The cooking chamber is connected via a tubular or tubular vapor channel 19 with a spiral casing 21 arranged on the cover-side muffle insulation 7 or the bottom plate 11 of the exhaust air channel 9 for removing vapors arising during the cooking process. In the interior of the spiral housing 21, a fan of a Wrasengebläses 22 is supported. The fan blower 22 pulls, if necessary, controlled by the control unit of the oven 1, the hot vapors from the oven muffle 5 through the vapor channel 19 in the spiral housing 21 and pushes the vapor from a in the edge region Alternatively, the Wrasenlüfter be disposed in the vapor channel and be dispensed with the volute casing when the Wrasenkanal extends with a Wraseneinblasöffnung into the edge region of the exhaust duct 9.

Im Bereich der Wraseneinblasöffnung 23 ist in Verlängerung des Wrasenkanals 19 bzw. des Spiralgehäuses 21 ein Wrasenkanal-Anschlußstück 25 vorgesehen. Dieses erstreckt sich etwa über die Hälfte der Breite des Abluftkanales 9 im Bereich des Anschlußstückes 25 bzw. der diesen begrenzenden Deckhaube 13. Dabei ist das Wrasenkanal-Anschlußstück 25 durch eine in der Bodenplatte 11 eingeprägte längliche Vertiefung 27 (Fig. 1) und ein auf der Bodenplatte 11 montiertes Wrasenleitblech 29 gebildet. Alternativ könnte das Wrasenleitmittel 29 auch mit einem geeigneten Kunststoffmaterial realisiert sein. Zwischen den der Kühlluftausblasöffnung 17 zugewandten Kanten des Wrasenleitbleches 29 und der Vertiefung 27 der Bodenplatte 11 sind zwei voneinander beabstandete Wrasenausblasöffnungen 31 des Wrasenkanal-Anschlußstückes 25 gebildet (Fig. 2, 3). Während die vom Wrasengebläse 22 geringer beabstandete erste Wrasenausblasöffnung 31 sich nahezu über die Hälfte der Länge des Luftleitbleches 29 und im wesentlichen exakt zwischen den vorderen Kanten des Luftleitbleches 29 und der Vertiefung 27 der Bodenplatte 11 in diesem Bereich erstreckt, ist die vom Wrasengebläse 22 weiter beabstandete zweite Wrasenausblasöffnung 31 kürzer ausgebildet und schräg zur ersten Wrasenausblasöffnung angeordnet. Um für die zweite Wrasenausblasöffnung 31 in diesem Bereich ebenfalls einen ausreichenden Öffnungsquerschnitt bereitzustellen, ist das Wrasenleitblech 29 im Vergleich zum Kantenverlauf der Vertiefung 27 zurückgeschnitten. Das Wrasenleitblech 29 weist einen haubenförmigen Anschlußabschnitt 33 auf, dessen Einlaßquerschnitt dem der Wraseneinblasöffnung 23 des Spiralgehäuses 21 entspricht. An den Anschlußabschnitt 33 schließt sich ein flach nach unten gezogener Strömungsabschnitt 35 des Wrasenleitbleches 29. Im Strömungsabschnitt 35 ragt das Wrasenleitblech 29 nur geringfügig über die Oberseite der Bodenplatte 11 in den Abluftkanal 9. Damit ist sichergestellt, daß die von dem Kühlluftgebläse 15 im Abluftkanal 9 geförderte Strömung nur geringfügig durch den quer zur Abluft-Hauptströmungsrichtung angeordneten Wrasenkanal-Anschlußstück beeinträchtigt ist. Aufgrund der Vertiefung 27 weist das Wrasenkanal-Anschlußstück 25 im Strömungsabschnitt 35 etwa den gleichen freien Strömungsquerschnitt auf wie im Anschlußabschnitt 33 bzw. der Wraseneinblasöffnung 23 des Spiralgehäuses 21.In the area of the Wraseneinblasöffnung 23 a Wrasenkanal fitting 25 is provided in extension of the Wrasenkanals 19 and the spiral housing 21. This extends approximately over half the width of the exhaust duct 9 in the region of the connecting piece 25 or the limiting cover hood 13. The Wrasenkanal connector 25 is characterized by an embossed in the bottom plate 11 elongated recess 27 (FIGS. Fig. 1 ) and a mounted on the bottom plate 11 Wrasenleitblech 29 is formed. Alternatively could the Wrasenleitmittel 29 may also be realized with a suitable plastic material. Between the Kühlluftausblasöffnung 17 facing edges of the Wrasenleitbleches 29 and the recess 27 of the bottom plate 11 are two spaced Wrasenausblasöffnungen 31 of the Wrasenkanal fitting 25 is formed ( Fig. 2 . 3 ). While the first Wrasenausblasöffnung 31 less spaced by the Wrasengebläse 22 extends almost over half the length of the baffle 29 and substantially exactly between the front edges of the baffle 29 and the recess 27 of the bottom plate 11 in this area, which is further spaced from the fan blower 22 second Wrasenausblasöffnung 31 formed shorter and arranged obliquely to the first Wrasenausblasöffnung. In order to also provide a sufficient opening cross-section for the second Wrasenausblasöffnung 31 in this area, the Wrasenleitblech 29 is cut back compared to the edge profile of the recess 27. The Wrasenleitblech 29 has a hood-shaped connection portion 33, whose inlet cross section corresponds to the Wraseneinblasöffnung 23 of the spiral housing 21. In the flow section 35, the Wrasenleitblech 29 protrudes only slightly above the top of the bottom plate 11 in the exhaust duct 9. This ensures that the of the cooling air fan 15 in the exhaust duct 9 funded flow is only slightly affected by the transversely arranged to the exhaust main flow direction Wrasenkanal fitting. Due to the recess 27, the Wrasenkanal connector 25 in the flow section 35 about the same free flow cross-section as in the connection section 33 and the Wraseneinblasöffnung 23 of the spiral housing 21st
