Description

Die Erfindung bezieht sich auf eine Backofentür zum Verschließen der Beschickungsöffnung des Garraumes eines vorzugsweisen pyrolytisch selbstreinigenden Backofens mit zumindest einer frontseitigen und einer dem Garraum zugewandten Scheibe vorzugsweise aus Glasmaterial, welche Scheiben einen Tür-Hohlraum begrenzen, wobei die frontseitige Scheibe an der Innenseite zumindest partiell von einer die vom Garraum ausgehenden Wärmeenergie am erreichen der frontseitigen Scheiben hemmenden, Wärmestrahlung reflektierenden Platte überdeckt ist.The invention relates to a oven door for closing the feed opening of the cooking chamber of a preferred pyrolytic self-cleaning oven with at least one front and a cooking chamber facing pane preferably made of glass material, which define a door cavity, the front pane on the inside at least partially a thermal energy emanating from the cooking chamber is covered on the plate of the heat-reflecting reflective plate which arrests the front pane.

Die US 4 084 571 A beschreibt einen pyrolytisch selbstreinigenden Ofen mit einer Tür, bei welcher im Bereich eines Sichtfensters eine äußere Glasscheibe und zwei innere Glasscheiben angeordnet sind. Zwischen der äußeren Glasscheibe und den inneren Glasscheiben ist ein Löcher aufweisender Schild aus eloxiertem Aluminium angeordnet.The US 4 084 571 A describes a pyrolytic self-cleaning oven with a door in which an outer glass pane and two inner glass panes are arranged in the region of a viewing window. Between the outer glass pane and the inner glass panes, there is a perforated plate made of anodized aluminum.

Die US 3 717 138 A beschreibt eine Tür für einen selbstreinigenden Ofen, bei welcher zwischen einer frontseitigen Glasscheibe und zwei rückwärtigen Glasscheiben ein verschwenkbarer Schild aus Aluminium angeordnet ist.The US 3 717 138 A describes a door for a self-cleaning oven, in which a pivotable shield made of aluminum is arranged between a front glass pane and two rear glass panes.

Bei Backofentüren mit Durchsichtfenster zum Garraum, insbesondere bei Backöfen mit so genannter pyrolytischen Selbstreinigung mit einer Selbstreinigungstemperatur von über 400°C im Garraum ist es bekannt, innerhalb eines durch eine frontseitige Glasscheibe einerseits und einer dem Garraum zugewandten Glasscheibe andererseits gebildeten Tür-Hohlraumes wärmedämmende Abschirmmittel anzuordnen, die eine thermische Übertragung der vom Garraum ausgehenden Wärmeenergie, insbesondere Wärmestrahlung auf die frontseitige Scheibe zumindest hemmen sollen, so dass auch bei Selbstreinigungsbetrieb an der Außenseite der Frontscheibe eine für den Menschen unschädliche Berührungstemperatur nicht überschritten wird.In oven doors with see-through window to the cooking chamber, especially in ovens with so-called pyrolytic self-cleaning with a self-cleaning temperature of about 400 ° C in the oven, it is known to arrange heat-insulating shielding within a glass pane formed by a front glass pane on the one hand and the cooking chamber facing glass , which should at least inhibit a thermal transfer of emanating from the oven heat energy, in particular heat radiation on the front pane, so that even in self-cleaning operation on the outside of the windscreen not harmless to humans touch temperature is not exceeded.

Hierzu ist es bekannt, im Hohlraum zwischen der äußeren und der inneren Glasscheibe eine aus Durchsichtgründen perforierte Platte anzuordnen, deren dem Garraum zugewandte Seite Wärmestrahlen reflektierend ausgebildet ist und im übrigen aus thermisch isolierenden Material besteht. Ferner ist es bekannt, unmittelbar auf die Innenseite der frontseitigen Glasscheibe eine thermisch wirksame Reflektionsschicht durch ein Druck- oder Beschichtungsverfahren aufzubringen (DE-GM-9321480-U1, DE-OS-10162220-A1 ).For this purpose, it is known to arrange in the cavity between the outer and the inner glass pane a perforated plate for reasons of transparency, whose cooking chamber facing side heat rays is reflective and otherwise consists of thermally insulating material. Furthermore, it is known, directly on the inside of the Front glass pane to apply a thermally effective reflection layer by a printing or coating process (DE-GM-9321480-U1, DE-A-10162220-A1 ).

Schließlich wird bei einer bekannten Gargerätetür ( EP 1 039 232 A2 ) vorgeschlagen zwischen einem mehrlagigen, isolierenden Scheibenpaket im Bereich der dem Garraum zugewandten Scheibe und der frontseitigen Scheibe eine Zusatzscheibe mit einseitiger Verspiegelung anzuordnen zur Verbesserung der thermischen Isolation durch Reflektion der vom Garraum ausgehenden Wärmestrahlung.Finally, in a known cooking appliance door ( EP 1 039 232 A2 ) proposed between a multi-layer, insulating disk package in the region of the cooking chamber facing disc and the front pane an additional disc with one-sided mirroring to improve the thermal insulation by reflection of the emanating from the oven heat radiation.

Der vorliegenden Erfindung ist die Aufgabe gestellt, eine Backofentür so auszugestalten, dass bei minimaler Bautiefe der Backofentür eine über die gesamte Fläche der frontseitigen Scheibe wirksame maximale Wärmedämmung im Tür-Hohlraum bezüglich der vom Garraum ausgehenden Wärmeenergie erreichbar ist.The present invention has the object of providing a oven door in such a way that with a minimum depth of the oven door over the entire surface of the front pane effective maximum thermal insulation in the door cavity with respect to the emanating from the oven heat energy can be achieved.

Dies wird bei der eingangs genannten Backofentür durch die Merkmale des Anspruchs 1 erreicht.This is achieved in the aforementioned oven door by the features of claim 1.

Aufgrund der eng benachbarten Platzierung der Platte vor der frontseitigen Oberfläche ergibt sich in einfacher und kostensparender Weise die Möglichkeit, den geringen Abstand von vorzugsweise 1 bis 5 mm und damit die Weite des Strömungskanals konstant zu halten, dadurch, dass die Platte an wenigen Stellen Ausprägungen aufweist, die eine dem gewünschten Abstand der Platte von der frontseitigen Scheibe bzw. deren der Platte unmittelbar benachbarten Oberfläche entsprechende Prägetiefe besitzen, mit denen die Platte sich punktuell unmittelbar oder mittelbar an der Scheibe bzw. der Oberfläche abstützt. Derartige Ausprägungen als Abstandselemente sind sehr wirtschaftlich und in beliebiger Anzahl herzustellen und gewährleisten zum einen die geforderte konstante Weite des Strömungskanals, verhindern zum anderen durch deren nur punktuellen Stützflächen eine nennenswerte Wärmeleitung zur Scheibe und können z.B. mittels eines Klebestoffes oder dergleichen als Verbindungselemente für die mechanische Verbindung von Platte und Oberfläche verwendet werden.Due to the closely adjacent placement of the plate in front of the front surface results in a simple and cost-saving way, the small distance of preferably 1 to 5 mm and thus to keep the width of the flow channel constant, characterized in that the plate has a few places forms having an embossing depth corresponding to the desired distance of the plate from the front pane or its surface immediately adjacent to the surface, with which the plate is selectively supported directly or indirectly on the disc or the surface. Such characteristics as spacers are very economical and produce in any number and ensure on the one hand the required constant width of the flow channel, prevent on the other by their only selective support surfaces a significant heat conduction to the disc and can eg by means of an adhesive or the like as connecting elements for the mechanical connection be used by plate and surface.

Versuche haben ergeben, dass man dann mit konstruktiv einfachen und auch nur partiell, d.h. außerhalb des üblicher Weise vorhandenen Durchsichtfensters in der Backofentür, anzuwendenden Mitteln eine bestmögliche thermische Abschottung der frontseitigen Scheibe, vorzugsweise Glasscheibe, erhält, wenn unmittelbar vor der Frontscheibe eine wesentliche Strömung, d.h. Abströmung der auch im frontseitigen Bereich des Tür-Hohlraumes immer noch vorhandenen erhitzten Luft durch natürliche Konvektion und gegebenenfalls zusätzlich durch eine gewisse Saugwirkung stattfindet. Es hat sich gezeigt, dass eine solche Luftströmung dann optimierbar ist, wenn die reflektierende Platte sehr eng der davor liegenden Oberfläche der Glasscheibe oder einer Wärmeleitplatte oder dergleichen benachbart ist jedoch mit einem Abstand, der eine Luftströmung noch zulässt innerhalb des zumindest nach oben offenen Strömungskanals. Die Abströmung wird dann besonders gut, wenn der genannte Abstand so bemessen ist, dass im Strömungskanal eine laminare und damit kontinuierlich fließend Strömung stattfindet, statt einer turbulenten, die erhitzte Luft in entgegengesetzte Richtungen transportierenden Luftbewegung. Eine solche laminare Strömung erhält man dann, wenn die Platte mit einem Abstand von ungefähr 1 bis 5 mm vor der benachbarten Scheibe bzw. deren der Platte unmittelbar benachbarten Oberfläche angeordnet ist.Experiments have shown that you then with structurally simple and only partially, i. outside the usual viewing window in the oven door, the means to be applied the best possible thermal foreclosure of the front pane, preferably glass, receives, when in front of the windshield, a substantial flow, i. Outflow of even in the front region of the door cavity still existing heated air by natural convection and optionally additionally takes place by a certain suction. It has been found that such an air flow can be optimized if the reflecting plate is very closely adjacent to the front surface of the glass pane or a heat conduction plate or the like, but with a distance which still permits an air flow within the at least upwardly open flow channel. The outflow becomes particularly good when the said distance is such that a laminar and thus continuously flowing flow takes place in the flow channel, instead of turbulent air movement transporting the heated air in opposite directions. Such a laminar flow is obtained when the plate is placed at a distance of approximately 1 to 5 mm in front of the adjacent disk or its surface immediately adjacent to the disk.

Eine unter den gegebenen Umständen bestmögliche Wärmedämmung erhält man zusätzlich dann, wenn die genannte Platte in der Scheibenebene gut wärmeleitend ist, also gute Querleiteigenschaften besitzt, wie z.B. bei Verwendung von Aluminium, bei relativ geringem thermischen Emissionsverhalten. Auf diese Weise wird trotz der niemals vollkommen reflektierenden Eigenschaft der Platte eine partielle Erhitzung durch Wärmeleitung auf die übrigen Plattenteile verteilt und insgesamt minimiert.In addition, the best possible thermal insulation under the given circumstances is obtained if the said plate is good heat-conducting in the plane of the pane, that is to say has good transverse-guiding properties, such as, for example, when using aluminum, with relatively low thermal emission behavior. In this way, despite the never completely reflecting property of the plate, a partial heating is distributed by heat conduction to the remaining plate parts and minimized overall.

Eine weitere Verbesserung der Wärmedämmwirkung wird gemäß einer Weiterbildung der Erfindung dadurch erhalten, dass sich die Platte eng benachbart vor einer die frontseitige Scheibe zumindest partiell überdeckenden, der Scheibe unmittelbar eng benachbart zugeordneten Wärmeleitplatte angeordnet ist, die sich an der Scheibe abstützt. Auf diese Weise werden auch diejenigen nicht von der reflektierenden Platte überdeckten Bereiche der Scheibe, z.B. Glasscheibe, wirksam vor direkter Wärmestrahlung geschützt.A further improvement of the thermal insulation effect is obtained according to a development of the invention in that the plate is arranged closely adjacent to the front side disc at least partially overlapping, the disc directly adjacent closely associated heat conduction, which is supported on the disc. In this way, those areas of the disc not covered by the reflecting plate, e.g. Glass pane, effectively protected against direct heat radiation.

Die Erfindung ist anhand eines in der Zeichnung dargestellten Ausführungsbeispiels nachstehend erläutert.The invention is explained below with reference to an embodiment shown in the drawing.

Es zeigt:

It shows:
FIG. 1
a back view of the oven door according to the section line II in FIG. 2 .
FIG. 2
a executed as a sectional view plan view of the oven door according to the section line II-II in FIG. 2 ,

Die Backofentür gemäß den Figuren besteht im Wesentlichen aus einer frontseitigen Scheibe 1 aus Glas, an der im oberen Türbereich ein paar von metallischen, lang gestreckten Verbindungsholmen 2, z.B. durch Kleben, befestigt sind, welche Verbindungsholme 2 sich über nahezu die gesamte Bauhöhe der Backofentür erstrecken (Figur 1). Die Scheibe 1 ist rückseitig mit Ausnahme eines Durchsichtfensters 3 mit einer undurchsichtigen Farbe bedruckt. Mit ihren die Verbindungsholme 2 überragenden Rändern stützt sich in bekannter Weise die Scheibe 1 an der umlaufenden Dichtung eines Backofenflansches eines nicht dargestellten Backofens ab. An den innenseitigen Flächen der Verbindungsholme 2 ist eine innere, dem Garraum des Backofens zugewandte napfartig profilierte Scheibe 4 ebenfalls aus Glasmaterial befestigt. Die beiden Scheiben 1 und 4 begrenzen einen Tür-Hohlraum 5 innerhalb welchem sich ein wärmedämmendes Scheibenpaket 6, eine sich nur über den oberen, im Betrieb des Backofens am stärksten erhitzten Bereich der Backofentür erstreckende Platte 7 sowie eine unmittelbar auf der Innenseite der Scheibe 1 aufliegende Wärmeleitplatte 8 befindet.The oven door according to the figures consists essentially of a front glass pane 1, to which a pair of metallic, elongated connecting beams 2, for example by gluing, are fixed in the upper door region, which connecting beams 2 extend over almost the entire height of the oven door ( FIG. 1 ). The disc 1 is printed on the back with the exception of a see-through window 3 with an opaque color. With her the connecting beams 2 superior edges supported in a known manner, the disc 1 on the peripheral seal of a baking oven flange of a baking oven, not shown. On the inside surfaces of the connecting beams 2, an inner, the cooking chamber of the oven facing cup-shaped profiled disc 4 is also attached from glass material. The two disks 1 and 4 delimit a door cavity 5 within which a heat-insulating disk package 6, a plate 7 which extends only over the upper region of the oven door which is heated to the greatest extent during operation of the oven and directly on the inside of the disk 1 rests Heat conducting 8 is located.

Die Platte 7 besitzt an mehreren Stellen Ausprägungen 9 mit denen sich die Platte 7 punktuell mit einem Abstand a von 1 bis 5 mm an der benachbarten Oberfläche, beim Ausführungsbeispiel an der Wärmeleitplatte 8, abstützt und damit dazwischen einen zumindest nach oben und unten offenen Strömungskanals 10 begrenzt. Die aus Aluminium bestehende Platte 7 ist auf der dem Garraum, also der inneren Scheibe 4, zugewandten Innenseite mit einer Wärmestrahlen reflektierende Oberfläche versehen, gebildet z.B. durch Polieren dieser Plattenseite. Auf diese Weise wird ein Großteil der vom Garraum herkommenden und durch die innere Scheibe 4 hindurchtretenden Wärmestrahlung reflektiert und von der frontseitigen Scheibe 1 abgehalten. Der Wärmerest wird innerhalb der Wärme gut querleitenden Platte 7 verteilt, so dass sich keine überhitzten einzelnen Stellen ergeben. Jedoch wird auch im Bereich der frontseitigen Scheibe 1 durch Wärmestrahlung und Wärmeleitung die Luft innerhalb des Hohlraumes 5 erhitzt. Durch die Bildung des eng begrenzten Strömungskanals 10 erfolgt in diesem Hohlraum 5 durch natürliche Konfektion und gegebenenfalls auch durch Saugwirkung aufgrund eines oberhalb der Backofentür verlaufenden Abluftkanals mit erzwungener Luftströmung eine im Wesentlichen laminare Luftströmung wodurch die erhitzte Luft ständig nach oben transportiert und ins Freie abgeleitet wird. Auf diese Weise ergeben sich auch im oberen, stets am stärksten erhitzten Bereich des Tür-Hohlraumes 5, in welchem sich üblicher Weise ein Tür-Handgriff befindet, an der frontseitigen Oberfläche der Scheibe 1 mäßige Temperaturen auch bei Selbstreinigungstemperaturen im Backofen von über 400°C, bei denen bei Berührung z.B. eines Kindes keine Verletzung zu befürchten sind.The plate 7 has at several points forms 9 with which the plate 7 selectively at a distance a from 1 to 5 mm on the adjacent surface, in the embodiment of the heat conduction plate 8, supported and thus therebetween an at least up and down open flow channel 10th limited. The existing aluminum plate 7 is provided on the cooking chamber, so the inner pane 4, facing the inside with a heat-reflecting surface, formed for example by polishing this side of the plate. In this way, a large part of the heat coming from the cooking chamber and passing through the inner pane 4 is reflected and kept away from the front pane 1. The heat test is distributed within the heat well-conducting plate 7, so that there are no overheated individual sites. However, the air inside the cavity 5 is also heated in the region of the front pane 1 by heat radiation and heat conduction. Due to the formation of the narrow flow channel 10 takes place in this cavity 5 by natural clothing and possibly also by suction due to a running above the oven door exhaust air duct with forced air flow, a substantially laminar air flow whereby the heated air is constantly transported up and discharged into the open. In this way, there are also in the upper, always most heated area of the door cavity 5, in which a conventional manner Door handle is located on the front surface of the disc 1 moderate temperatures even at self-cleaning temperatures in the oven of about 400 ° C, in which, for example, a child no injury to be feared.
