Description

Die Erfindung betrifft einen Einbaubratofen nach dem Oberbegriff des Patentanspruchs.The invention relates to a built-in oven according to the preamble of the claim.

Ein Einbaubratofen dieser Art ist aus der DE-A-2741917 bekannt. Bei diesem Einbaubratofen weist der Wrasenkanal der Wrasenabführungseinrichtung, der die Wrasenöffnung in der Bratofenmuffeldecke mit der Wrasenöffnung im Kochfeld verbindet, mehrere Krümmungen auf. Dadurch wird der Wrasenstrom auf seinem Weg mehrmals umgelenkt. Dies führt zu einer Herabsetzung der Wrasen-Abzugsgeschwindigkeit. Die Folge davon ist, daß der heiße Wrasen vorzeitig abkühlt und an den kühleren Wandflächen des Wrasenabführungskanales kondensiert. Eine weitere Schwierigkeit bereitet auch das Ankoppeln des an der Wrasenanschlußöffnung der Bratofenmuffel angebrachten Wrasenabführungskanalteils mit dem Verbindungsteil im Kochfeldbereich unterhalb der Arbeitsplatte, da die Ankoppel- bzw. Verbindungsstelle nicht von oben her einsehbar und daher auch nicht ausgerichtet werden kann. Des weiteren ist hier der konstruktive und materialmäßige Aufwand beträchtlich und führt dadurch zu einer teueren Fertigung, die bei hohen Stückzahlen in der Konsumgüter-Industrie unbedingt vermieden werden sollte.A built-in oven of this type is known from DE-A-2741917. In this built-in roasting oven, the vapor channel of the vapor removal device, which connects the vapor opening in the oven cavity ceiling with the vapor opening in the cooktop, has several curvatures. As a result, the stream of vapors is redirected several times on its way. This leads to a reduction in the vapor extraction speed. The result of this is that the hot vapors cool down prematurely and condense on the cooler wall surfaces of the vapors discharge duct. Another difficulty is also the coupling of the vapor discharge duct part attached to the vapor connection opening of the roasting oven muffle with the connecting part in the hob area below the worktop, since the coupling or connecting point cannot be seen from above and therefore cannot be aligned. Furthermore, the constructive and material expenditure is considerable and leads to an expensive production, which should be avoided in the case of large quantities in the consumer goods industry.

Weiterhin ist eine Wrasenabführungseinrichtung für einen unterbaufähigen Bratofen aus dem Patent Abstract of Japan, Band 8, Nr. 267, vom 07.12.1984 bekannt, die aus einem vertikalen Rohrzylinder besteht, der auf der Wrasenöffnung des Bratofens gesetzt und innerhalb eines den Bratofen-Überbau durchsetzenden Schachtes geführt ist und im Bereich einer Öffnung in der Oberseite des Überbaus frei endet. Diese Öffnung ist durch eine am Bratofen-Überbau angebrachte Auslaßhaube überdeckt. Bei dieser Wrasenabführungseinrichtung sind wohl die beiden zu verbindenden Wrasenöffnungen zueinander korrespondierend angeordnet, jedoch läßt bei dieser Einrichtung der Zugang bzw. Zugriff zum Zwecke einer Reinigung durch den Benutzer noch Wünsche offen.Furthermore, a vapor removal device for a built-in roasting oven is known from the Patent Abstract of Japan, Volume 8, No. 267, dated December 7, 1984, which consists of a vertical tubular cylinder which is placed on the vaporizing opening of the roasting oven and within a penetrating area of the roasting oven superstructure Shaft is guided and ends freely in the area of an opening in the top of the superstructure. This opening is covered by an outlet hood attached to the roasting oven superstructure. In this vapor removal device, the two vapor openings to be connected are arranged to correspond to one another, but in this device the access for the purpose of cleaning by the user still leaves something to be desired.

Der Erfindung liegt die Aufgabe zugrunde, eine Wrasenabführungseinrichtung für einen Einbaubratofen der in Rede stehenden Art zu schaffen, die einerseits einen kurzen Strömungsweg aufweist, so daß der Wrasen aus der Bratofenmuffel zügig und ohne nennenswerte Abkühlung (Kondensatbildung) zur Austrittsöffnung im Kochfeld strömen kann und die andererseits nach Einbringen des Bratofens unter der Arbeitsplatte und nach Montage des Kochfeldes in der Arbeitsplatte mühelos zusammengekoppelt werden kann.The invention has for its object to provide a vapor removal device for a built-in oven of the type in question, which on the one hand has a short flow path, so that the vapors can flow quickly and without significant cooling (condensate formation) to the outlet opening in the hob and the on the other hand, after inserting the roasting oven under the worktop and after installing the hob in the worktop, it can be easily coupled together.

Die Lösung dieser Aufgabe gemäß der Erfindung ist dem kennzeichnenden Teil des Patentanspruchs zu entnehmen.The solution to this problem according to the invention can be found in the characterizing part of the patent claim.

Die vorgeschlagene Wrasenabzugseinrichtung zeichnet sich durch einen besonders kurzen Wrasenabführungsweg aus. Die Herstellung der Verbindung zwischen Kochfeld und Bratofenmuffel ist leicht durchführbar, da ein Zugriff von oben her durch die Abzugsöffnung im Kochfeldbereich zum Ausrichten des an der Bratofenmuffel angebrachten Kanalteils möglich ist. Des weiteren kann auch die das Kochfeld lose durchsetzende Rohrhülse zwecks Reinigung jederzeit mit einem Handgriff herausgenommen werden.The proposed vapor extraction device is characterized by a particularly short vapor discharge path. The connection between the cooktop and the roasting oven muffle is easy to carry out, since access is possible from above through the extraction opening in the cooktop area to align the duct part attached to the roasting oven muffle. Furthermore, the tubular sleeve which passes loosely through the hob can be removed at any time for cleaning purposes.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird anhand dieser nachfolgend näher beschrieben.An embodiment of the invention is shown in the drawing and is described in more detail below with reference to this.

Die Zeichnung zeigt einen Ausschnitt aus der deckenseitigen Muffelwand eines Ein- bzw. Unterbaubratofens mit der darüber angeordneten Arbeitsplatte mit eingelassenem Kochfeld und mit der diese beiden Teile verbindenden Wrasenabzugseinrichtung in Schnittdarstellung sowie mögliche Lagen der Wrasenöffnung im Kochfeld, zu der eine Verbindung durch Ausrichten des Wrasenabführungskanals herstellbar ist.The drawing shows a section from the ceiling-side muffle wall of a built-in or built-in oven with the worktop arranged above it with an embedded hob and with the vapor extraction device connecting these two parts in a sectional view, as well as possible positions of the vapor opening in the hob, to which a connection can be established by aligning the vapor discharge channel is.

Mit 1 ist eine nur teilweise dargestellte Bratofenmuffel bezeichnet, die wesentlicher Bestandteil eines Ein- bzw. Unterbaubratofens ist. Die Wände der Bratofenmuffel 1 sind mit einer üblichen thermischen Isolierschicht 2 umgeben. In der Bratofenmuffeldecke 3 ist eine Wrasenöffnung 4 ausgebildet, die zweckmäßig im hinteren Teil bzw. Abschnitt der Muffeldecke gelegt ist. In Verlängerung der Wrasenöffnung 4 ist an der Bratofenmuffeldecke 3 ein die Isolierschicht 2 durchsetzender Flanschrohrstutzen 5 befestigt. Oberhalb der Isolierschicht 2 ist die Bratofengehäuseabdeckung 6 angeordnet, die eine mit dem Flanschrohrstutzen 5 korrespondierende Durchführungsöffnung 7 aufweist. In dem Flanschrohrstutzen 5 ist ein Rohrkörper 8 zentriert, der aus einem starren Rohrstück oder aus einem Metallschlauch bestehen kann. Das freie bzw. Ankoppelende 9 des Rohrkörpers 8 ist zweckmäßig nach außen zu erweitert, d.h. trichterartig ausgebildet.1 denotes a roasting oven muffle, which is only partially shown, and which is an integral part of a built-in or built-in oven. The walls of the roasting oven muffle 1 are surrounded by a conventional thermal insulating layer 2. In the roasting oven muffle ceiling 3, a vapor opening 4 is formed, which is expediently placed in the rear part or section of the muffle ceiling. In an extension of the vapor opening 4, a flange pipe stub 5 passing through the insulating layer 2 is attached to the roasting oven muffle ceiling 3. Above the insulating layer 2, the roaster housing cover 6 is arranged, which has a through opening 7 corresponding to the flange pipe socket 5. A tube body 8 is centered in the flange pipe socket 5, which can consist of a rigid piece of pipe or of a metal hose. The free or coupling end 9 of the tubular body 8 is expediently widened outwards, i.e. funnel-shaped.

Der beschriebene Einbaubratofen ist unterhalb einer in der Regel aus holzartigem Material bestehenden und mehrere Einheiten einer Küchenmöbelzeile abdeckenden Arbeitsplatte 10 angeordnet. In der Arbeitsplatte 10 ist ein Kochfeld 11 eingelassen, das beim beschriebenen Ausführungsbeispiel ein Glaskeramikkochfeld mit einer die Kochstellenbeheizungen tragenden Bodenwanne 12 ist. Im hinteren Teil bzw. Randbereich des Kochfeldes 11 und korrespondierend dazu in der Bodenwanne 12 ist je eine Wrasenöffnung 13 bzw. 13′ ausgebildet. Durch diese Öffnungen ist von oben her eine lose Rohrhülse 14 einführbar, welche die Tiefe des Kochfeldes 11 durchsetzt und in angekoppeltem Eingriff mit dem trichterartigen Ankoppelende 9 des Rohrkörpers 8 an der Bratofenmuffeldecke 3 bringbar ist. Die Rohrhülse 14 besitzt einen sich auf der Oberseite des Kochfeldes 11 abstützenden Auflagerand 15. Die Rohrhülse 14 kann auch zwecks Abschluß mit einer pilzartigen, entsprechende Wrasenauslaßöffnungen versehenen Abdeckkappe ausgerüstet werden.The built-in roasting oven described is arranged below a worktop 10 which generally consists of wood-like material and covers several units of a row of kitchen furniture. A hob 11 is embedded in the worktop 10, which in the exemplary embodiment described is a glass ceramic hob with a base pan 12 which supports the hotplate heaters. In the rear part or edge area of the hob 11 and correspondingly in the floor pan 12, a vapor opening 13 or 13 'is formed. Through these openings, a loose tubular sleeve 14 can be inserted from above, which penetrates the depth of the hob 11 and can be brought into coupling engagement with the funnel-like coupling end 9 of the tubular body 8 on the roasting oven muffle ceiling 3. The tubular sleeve 14 has a support edge 15 which is supported on the top of the hob 11 Pipe sleeve 14 can also be equipped with a mushroom-like cover cap provided with appropriate vapor outlet openings.

Dadurch, daß die Zusammenkoppelung des Rohrkörpers 8 mit der Rohrhülse 14 praktisch in vertikaler Richtung ausführbar ist, wird der kürzeste Wrasenweg zwischen dem Kochfeld 11 und der Bratofenmuffel 1 hergestellt. Des weiteren erlaubt die korrespondierende Anordnung der Öffnungen 13, 13′ im Kochfeld 11 und des Rohrkörpers 8 einen sichtbaren Eingriff von der Oberseite des Kochfeldes 11 her und damit ein Ausrichten des Rohrkörpers 8 in bezug zu den Öffnungen 13, 13′. Damit können Toleranzen sowohl bei den verschiedensten Kochfeldern als auch von der Senkrechten abweichende Lagen des Rohrkörpers 8 ausgeglichen und dieser in Deckung mit den Öffnungen 13, 13′ im Kochfeld 11 gebracht werden, so daß stets eine zuverlässige und damit sichere Zusammenkoppelung der in den Öffnungen 13, 13′ einführbaren losen Rohrhülse 14 mit dem Rohrkörper 8 gewährleistet ist.Because the coupling of the tubular body 8 with the tubular sleeve 14 can be carried out practically in the vertical direction, the shortest vapor path between the hob 11 and the roasting oven muffle 1 is produced. Furthermore, the corresponding arrangement of the openings 13, 13 'in the hob 11 and the tubular body 8 allows a visible engagement from the top of the hob 11 and thus aligning the tubular body 8 with respect to the openings 13, 13'. Thus, tolerances can be compensated for both in the most diverse cooktops as well as in the positions of the tubular body 8 which deviate from the vertical, and these are brought into coincidence with the openings 13, 13 'in the cooktop 11, so that a reliable and thus safe coupling of the openings 13 in the openings is always made , 13 'insertable loose tubular sleeve 14 with the tubular body 8 is ensured.
