Description

Die Erfindung betrifft einen Backofen, insbesondere Backofen für die Schaubäckerei, mit einem den durch eine Backofentür verschließbaren Backraum enthaltenden Backofengehäuse, dem ein oberhalb des Backraums angeordneter Dunstfang zugeordnet ist.The invention relates to an oven, in particular Oven for the show bakery, with one by one Oven door containing lockable baking space Oven housing, the one above the baking chamber arranged extractor is assigned.

Derartige bekannte Backöfen sind in der Praxis weit verbreitet, wobei diese zum effektiven Abzug der aus dem Backraum entweichenden Schwaden den oberhalb des Backraums angeordneten Dunstfang aufweisen, der auf der die Ofentür aufweisenden Seite den Backraum nach vorne zum Nutzer hin überragt, wobei die Form des Dunstfangs an die Form der Grundfläche des Backraumes angepaßt, also rechteckig ausgestaltet ist und um eine konstante Länge vor die Ofentür vorsteht, also über die Ofenfront hinausragt. Such known ovens are wide in practice widespread, this for effective deduction of the from The steam escaping from the baking chamber above the baking chamber arranged arranged muffler, which on the the oven door side facing the baking area towards the user towers, the shape of the muffler to the shape of the Base area of the baking chamber adjusted, i.e. rectangular is designed and a constant length in front of the Oven door protrudes, i.e. protrudes beyond the oven front.

Daraus ergibt sich, unter anderem aus ergonomischen und sicherheitstechnischen Gründen, daß der Backofen erhöht installiert werden muß, damit der über die Ofenfront hinausragende Teil des Dunstfanges sich oberhalb des Kopfes des Nutzers befindet, da andernfalls die Bewegungsfreiheit hinter der Verkaufstheke für die Verkaufsbäckerei stark eingschränkt wäre und zusätzlich die Sichtbarkeit des unterhalb des Dunstfanges und oberhalb der Ofentür angeordneten Bedienfeldes eingeschränkt würde. Bei zwei übereinander angeordneten Backöfen ist es mit nur einem, auf dem oben angeordneten Backofen plazierten Dunstfang nur unzureichend möglich, die Schwaden des unten angeordneten Backofens abzuziehen.This results, among other things, from ergonomic and safety reasons that the oven increases must be installed so that the over the furnace front protruding part of the extractor hood above the Head of the user, otherwise the Freedom of movement behind the sales counter for Sales bakery would be severely restricted and additional the visibility of the below the muffler and Control panel located above the oven door would be restricted. With two arranged one above the other Ovens with only one, arranged on the top Oven-positioned extractor trap is insufficient remove the steam from the oven below.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Backofen der eingangs genannten Art so auszubilden, daß die durch den Dunstfang gegebenen Beschränkungen bei der Plazierung des Backofens überwunden werden.The invention is therefore based on the object Train oven of the type mentioned so that the restrictions imposed by the haze on the Placement of the oven can be overcome.

Diese Aufgabe wird nach der Erfindung bei einem Backofen der eingangs genannten Art dadurch gelöst, daß der Dunstfang um eine vertikale Achse schwenkbar im Backofengehäuse gelagert und zwischen einer in das Backofengehäuse versenkten Ruhestellung und einer vor die Vorderfront des Backofengehäuses ragenden Betriebsstellung verstellbar ist.This object is achieved according to the invention in an oven of the type mentioned in that the Vapor trap can be swiveled around a vertical axis Oven casing stored and between one in the Oven housing recessed rest position and one in front of the Front position of the oven housing protruding operating position is adjustable.

Die Erfindung bietet den Vorteil, daß während des Backbetriebes bei geschlossener Ofentür der Dunstfang in das Backofengehäuse versenkt ist und in dieser Ruhestellung keine Beeinträchtigung der Bewegungsfreiheit für das Bedienpersonal darstellt. Wenn zum Ende des Backprozesses beim Öffnen der Ofentür der Schwadenabzug benötigt wird, kann der Dunstfang um die vertikale Achse aus seiner Ruhestellung herausgeschwenkt werden, wobei der Dunstfang in seiner Betriebsstellung nur an einer Seite des Backofens weit vor die Ofenfront ragt und sich bei kleinen Schwenkwinkeln an der vertikalen Achse nicht vor die Ofenfront verstellt, so daß an der vertikalen Achse keine Behinderung der Sichtbarkeit von dem Bedienfeld gegeben ist und auch keine Einschränkung der Bewegungsfreiheit bewirkt wird.The invention has the advantage that during the Baking operation with the oven door closed the oven housing is sunk and in this Rest position no impairment of freedom of movement represents for the operating personnel. If at the end of the Baking process when opening the oven door of the steam extraction is needed, the extractor can be positioned around the vertical axis be pivoted out of its rest position, the Vapor trap in its operating position only on one side of the oven protrudes far in front of the oven front small swivel angles on the vertical axis do not exist the furnace front adjusted so that on the vertical axis no obstruction to visibility from the control panel is given and also no restriction of Freedom of movement is effected.

Im Rahmen der Erfindung ist vorgesehen, daß die vertikale Achse für den Dunstfang an der selben Seite des Backofengehäuses wie die Scharniere für die Ofentür angeordnet sind, da so gegenüber dem Fall, bei dem die vertikale Achse beispielsweise mittig plaziert ist, um bei der sich öffnenden Ofentür nur im Bereich ihres freien Endes abzusaugen, eine parallel verlaufende Bewegung von der Ofentür und dem Dunstfang möglich ist. Die Fläche des von der Ofentür mit dem Backofengehäuse eingeschlossenen Spaltes korrespondiert dann mit der von dem Dunstfang bereitgestellten Fläche zur Absaugung hinsichtlich Größe und Form. Dazu ist bevorzugt, daß die vertikale Achse und die Drehachse der Scharniere koaxial ausgerichtet sind.In the context of the invention it is provided that the vertical Axis for the muffler on the same side of the Oven housing such as the hinges for the oven door are arranged as compared to the case where the vertical axis is placed in the middle, for example, at the opening of the oven door only in the area of your free End suction, a parallel movement of the oven door and the extractor is possible. The area of the enclosed by the oven door with the oven housing The gap then corresponds to that of the extractor provided area for suction in terms of size and shape. It is preferred that the vertical axis and the axes of rotation of the hinges are aligned coaxially.

Für eine vereinfachte Bedienung des Backofens und insbesondere des Dunstfanges ist ein Antrieb zur Verschwenkung des Dunstfangs vorgesehen.For simplified operation of the oven and especially the extractor is a drive for Swiveling the extractor provided.

Eine besonders bevorzugte Ausführungsform der Erfindung ist dadurch gekennzeichnet, daß der Antrieb zur zeitlich aufeinander abgestimmten Verstellung des Dunstfangs vor der sich nach dem Backvorgang automatisch öffnenden Ofentür vorgesehen ist, da so ohne einen Eingriff des Bedienpersonals ein lückenloser und vollständiger Abzug der Schwaden gewährleistet ist, also auch dann, wenn das Bedienpersonal hinter der Verkaufstheke anderen Beschäftigungen nachgeht. Von Vorteil ist auch, daß der Dunstfang sich schon vor dem Öffnen der Ofentür in der Betriebsstellung befindet, da sich durch die Luftansaugung des Ventilators eine Luftströmung aufbaut, die den vollständigen Abzug der Schwaden sicherstellt.A particularly preferred embodiment of the invention is characterized in that the drive for the time coordinated adjustment of the extractor the one that opens automatically after the baking process Oven door is provided, as without the intervention of the Operators a complete and complete deduction the swath is guaranteed, even if that Operating staff behind the other sales counter Employment. It is also advantageous that the Vapor trap even before opening the oven door in the Operating position is because of the air intake the fan builds up an air flow that the ensures that the swaths are completely withdrawn.

Im Hinblick auf die Anforderungen des Dauerbetriebes und die dazu erforderliche Robustheit umfaßt der Antrieb einen am Dunstfang angeschlossenen Doppelgelenkstab, der mit seinem gegenüberliegenden Ende an einem Linearmotor bzw einer Exzenterwelle befestigt ist.With regard to the requirements of continuous operation and the robustness required for this includes the drive double articulated rod connected to the muffler, which with its opposite end on a linear motor or an eccentric shaft is attached.

Um eine Verletzung des Bedienpersonals durch eine unkontrolliert aufspringende Ofentür zu vermeiden und den Schwaden einen definierten Abzugsweg vorzugeben, ist eine den Öffnungswinkel der sich automatisch öffnenden Ofentür begrenzende Türrastung vorgesehen.To prevent injury to the operating personnel to avoid opening the door uncontrolled and the Specifying swaths with a defined deduction path is one the opening angle of the automatically opening furnace door limiting door latch provided.

Zweckmäßiger Weise ist der Backofen dann so gestaltet, daß der Schwenkwinkel des Dunstfangs dem durch die Türrastung begrenzten Öffnungswinkel der Ofentür entspricht.The oven is then expediently designed such that the swivel angle of the extractor through the door catch limited opening angle of the oven door corresponds.

Da die aus dem Backraum entweichenden Schwaden nicht immer nach oben aufsteigen, sondern auch seitlich expandieren, sind an dem Dunstfang neben den nach unten zum Backraum weisenden Ansaugöffnungen zusätzlich seitliche Öffnungen in der Seitenfläche des Dunstfangs ausgebildet. Since the swath escaping from the baking chamber is not always climb up, but also expand sideways, are on the muffler next to the down to the baking room side suction openings formed in the side surface of the hood.

Um auch die während des Backbetriebes in erheblichem Umfang aus dem Backraum austretenden Schwaden auffangen zu können, ist der Backofen erfindungsgemäß so gestaltet, daß in den Dunstfang ein Schwadenkondensator integriert ist, und daß in der Ruhestellung des Dunstfangs zumindest teilweise die Ansaugöffnungen freiliegen, um die erforderliche Kühlluft für den Schwadenkondensator ansaugen zu können.In order also to a considerable extent during the baking operation Catch the amount of steam coming out of the baking chamber can, the oven is designed according to the invention so that a vapor condenser is integrated in the vapor trap, and that at least when the muffler is at rest some of the suction openings are exposed to the required cooling air for the steam condenser to be able to suck.

Damit die Frontfläche des Dunstfanges die gesamte Breite des Backofens einnehmen kann, ist vorgesehen, daß die Seitenfläche des Dunstfangs zur Frontfläche geneigt ausgerichtet ist, um eine Vergrößerung der Breitenabmessung beim Aufschwenken in die Betriebsstellung zu kompensieren.So that the front surface of the extractor cover the entire width the oven can take, it is provided that the Side surface of the muffler inclined to the front surface is aimed at an enlargement of the Width dimension when swiveling into the operating position to compensate.

Im Hinblick auf einen störungsfreien Betrieb ist vorgesehen, daß die Seitenfläche durch ein an dem Backofengehäuse angeordnetes Führungselement geführt ist.With a view to trouble-free operation provided that the side surface by a on the Oven housing arranged guide element is guided.

Hinsichtlich der Einfachheit des Aufbaus ist dabei bevorzugt, wenn das Führungselement durch ein T-förmiges Profilteil gebildet ist, das mit einem Schenkel in eine in der Seitenfläche ausgebildete Nut eingreift.With regard to the simplicity of the construction is included preferred if the guide element by a T-shaped Profile part is formed with a leg in one engages the side surface formed groove.

Im Rahmen der Erfindung ist es weiterhin möglich, wenn das Backofengehäuse zweiteilig mit einem separaten Dunstabzuggehäuse gestaltet ist, da die integrale Einbindung des Dunstfanges in das Backofengehäuse für das Funktionieren der Erfindung nicht erforderlich ist und bei dem modularen Aufbau ein Nachrüsten bereits existierender Backöfen ermöglicht wird. In the context of the invention it is also possible if the Oven housing in two parts with a separate one Extractor hood housing is designed as the integral Integration of the extractor in the oven housing for the Operation of the invention is not necessary and at the modular structure retrofits existing ones Ovens is enabled.

Der in der Zeichnung (Fig. 1 bis 8) dargestellte, für den Einsatz hinter Verkaufstheken in der Schaubäckerei vorgesehene Backofen 1 weist ein Backofengehäuse 2 auf, in dem der durch eine Ofentür 3 verschließbare Backraum 4 ausgebildet ist. Diese Ofentür 3 ist über Scharniere an dem Backofengehäuse 2 angelenkt und öffnet sich nach dem Ende des Backvorganges automatisch um einen durch eine Türrastung begrenzten Öffnungswinkel alpha. Um die dabei aus dem Backraum 4 austretenden Schwaden effektiv abzuziehen, ist dem Backofen 1 ein Dunstfang 5 zugeordnet, der bei dem in der Zeichnung dargestellten Ausführungsbeispiel in einem separaten Dunstabzugsgehäuse 6 angeordnet ist, aber auch unmittelbar in das Backofengehäuse 2 integriert sein kann. Der Dunstfang 5 ist oberhalb des Backraums 4 angeordnet und zeichnet sich dadurch aus, daß der Dunstfang 5 um eine vertikale, koaxial zur Drehachse der Scharniere ausgerichtete Achse 7 schwenkbar gelagert ist und zwischen einer in das Backofengehäuse 2 versenkten, aus Fig. 1 ersichtlichen Ruhestellung und einer vor die Vorderfront des Backofengehäuse 2 ragenden, aus Fig. 2 ersichtlichen Betriebsstellung schwenkbar ist.The shown in the drawing (Fig. 1 to 8), for the Use behind sales counters in the show bakery The provided oven 1 has an oven housing 2, in which is the baking chamber 4 which can be closed by an oven door 3 is trained. This oven door 3 is hinged on the oven housing 2 hinged and opens after End of the baking process automatically by one Door latch limited opening angle alpha. To get it Swaths emerging from the baking chamber 4 effectively deduct, an oven 5 is assigned to the oven 1, the one shown in the drawing Embodiment in a separate Extractor hood housing 6 is arranged, but also directly can be integrated in the oven housing 2. The Vapor trap 5 is arranged above the baking chamber 4 and is characterized in that the extractor 5 by a vertical, coaxial to the axis of rotation of the hinges aligned axis 7 is pivotally mounted and between one sunk into the oven housing 2 from FIG. 1 apparent rest position and one in front of the front of the oven housing 2 protruding, shown in Fig. 2 Operating position is pivotable.

Bei Anblick der Fig. 1 fällt unmittelbar auf, daß in der Ruhestellung der Dunstfang 5 keinen zusätzlichen Raum vor dem Backofengehäuse 2 beansprucht und damit die Bewegungsfreiheit des Bedienpersonals hinter der Verkaufstheke nicht einschränkt. In der Betriebsstellung ragt der Dunstfang 5 infolge der Schwenkbewegung nur einseitig aus dem Backofengehäuse 2 hervor, so daß dadurch die Einschränkung der Bewegungsfreiheit reduziert ist und weiterhin die Sichtbarkeit des Bedienfeldes 8 von dem Backofen 1 unverändert gegeben bleibt. Der Schwenkwinkel des Dunstfanges 5 entspricht dabei dem durch die Türrastung begrenzten Öffnungswinkel alpha der Ofentür 3, da dies völlig ausreicht, die aus dem geöffneten Spalt zwischen der Ofentür 3 und dem Backofengehäuse 2 aufsteigenden Schwaden abzuziehen. Aus Fig. 2 ist auch unmittelbar ersichtlich, daß die Form des Dunstfanges 5 in der Betriebsstellung der Form des Spaltes angepaßt ist, der Dunstfang 5 also dort, wo infolge einer nur geringen Spaltöffnung nur wenig Schwaden aufsteigen, auch nur gering vor die Vorderfront vorsteht.When looking at Fig. 1 immediately noticeable that in the Rest position of the extractor 5 no additional space claimed the oven housing 2 and thus the Freedom of movement for the operators behind the Sales counter not restricted. In the operating position the extractor 5 only protrudes as a result of the pivoting movement from one side of the oven housing 2, so that thereby the restriction of freedom of movement is reduced and continue the visibility of the control panel 8 of the Oven 1 remains unchanged. The swivel angle the extractor 5 corresponds to that by Door opening limited opening angle alpha of the oven door 3, since this is completely sufficient from the open gap between the oven door 3 and the oven housing 2 deduct ascending swaths. From Fig. 2 is also immediately apparent that the shape of the muffler 5 in the operating position is adapted to the shape of the gap, the extractor 5 where there is only a small Cleavage rise little swaths, even protrudes slightly in front of the front.

Zur Schwenkung des Dunstfanges 5 ist ein Antrieb vorgesehen, der einen am Dunstfang 5 angeschlossenen Doppelgelenkstab 9 umfaßt, der mit seinem gegenüberliegenden Ende an einem Linearmotor 10 befestigt ist. Denkbar sind natürlich gleichfalls andere Lösungen, die beispielsweise eine Exzenterwelle zur Verstellung des Doppelgelenkstabes 9 aufweisen. Der Antrieb wird dazu genutzt, den Dunstfang 5 zeitlich aufeinander abgestimmt mit der sich nach dem Backvorgang automatisch öffnenden Ofentür 3 zu verstellen, um ca. 10-15 Sekunden vor dem Öffnen der Ofentür 3 den Dunstfang 5 in die Betriebsstellung zu schwenken und so bereits einen Luftstrom zu erzeugen, der auch die ersten Schwaden sicher erfaßt. Das Schwenken des Dunstfangs 5 signalisiert auch das bevorstehende Ende der Backzeit mit dem Öffnen der Ofentür 3.A drive is for pivoting the extractor 5 provided that one connected to the extractor 5 Includes double joint rod 9, with his opposite end attached to a linear motor 10 is. Other solutions are of course also conceivable, which, for example, an eccentric shaft for adjusting the Have double joint rod 9. The drive becomes this used, the extractor 5 coordinated in time with the one that opens automatically after the baking process To adjust oven door 3 to about 10-15 seconds before Open the oven door 3, the extractor 5 in the Swivel operating position and so already one Generate airflow that is safe even the first swaths detected. The pivoting of the extractor 5 also signals the upcoming end of the baking time with the opening of the Oven door 3.

Insbesondere aus Fig. 2 ist ersichtlich, daß an dem Dunstfang 5 neben den nach unten zum Backraum 4 weisenden Ansaugöffnungen zusätzlich seitliche Öffnungen 11 in der Seitenfläche 12 des Dunstfangs 5 ausgebildet sind, die dazu dienen, die seitlich aus dem Backraum 4 austretenden Schwaden anzusaugen.In particular, from Fig. 2 it can be seen that on the Vapor trap 5 next to the ones pointing down to the baking chamber 4 Intake openings additional side openings 11 in the Side surface 12 of the extractor 5 are formed, the serve to emerge laterally from the baking chamber 4 To suck up steam.

In den Dunstfang 5 ist ein Schwadenkondensator 13 integriert. Um die während des Backbetriebes austretenden Schwaden diesem zuführen zu können, liegen in der Ruhestellung des Dunstfangs 5 zumindest teilweise die Ansaugöffnungen frei, was in einfacher Weise dadurch erreicht ist, daß der Dunstfang 5 mit Abstand zu der darunterliegenden Platte des Backofengehäuses 2 angeordnet ist.A vapor condenser 13 is in the vapor trap 5 integrated. To those who escape during baking To be able to feed windrows into it lies in the Rest position of the extractor 5 at least partially Intake openings free, which in a simple way is achieved that the extractor 5 at a distance from the underlying plate of the oven housing 2 arranged is.

Die Seitenfläche 12 des Dunstfangs 5 ist geneigt zur Frontfläche 14 ausgerichtet und durch ein an dem Backofengehäuse 2 angeordnetes Führungselement 15 geführt, das als ein T-förmiges Profilteil 16 ausgebildet ist, das mit einem Schenkel 17 in eine in der Seitenfläche 12 des Dunstfanges 5 ausgebildete Nut 18 eingreift.The side surface 12 of the extractor 5 is inclined to Front surface 14 aligned and by one at the Oven housing 2 arranged guide element 15 guided, which is designed as a T-shaped profile part 16, the with a leg 17 in a in the side surface 12 of the Vapor trap 5 engages groove 18.
