Description

Die Erfindung betrifft eine Dunstabzugshaube für einen Herd, eine Kochstelle umfassend ein als Unterbauhaube ausgelegtes Gehäuse, in dem zwei nebeneinander liegende Radiallüfter angeordnet sind, deren nebeneinander liegende Luftführungskanäle zur Rückseite des Gehäuses in einen gemeinsamen Luftführungskanal münden, wobei im Bereich des gemeinsamen Abluftkanals eine Einrichtung vorhanden ist, mit der die Dunstabzugshaube wahlweise als Umlufthaube oder als Ablufthaube betreibbar ist.The invention relates to an extractor hood for a stove, a cooking area comprising a housing designed as a base hood, in which two adjacent radial fans are arranged, the adjacent air ducts open to the back of the housing in a common air duct, wherein in the region of the common exhaust duct means available is, with which the extractor hood is either operable as a circulating air hood or as an exhaust hood.

Aus dem Stand der Technik sind Dunstabzugshauben bekannt, die wahlweise umschaltbar sind, um sie als Umluft- oder als Ablufthaube zu betreiben. Dies aus dem Grund, um Wärmeverluste vom Innenbereich zum Außenbereich eines Gehäuses zu vermeiden. So besteht bei einer derartigen umschaltbaren Dunstabzugshaube die Möglichkeit beispielsweise im Sommer die Dunstabzugshaube als Ablufthaube zu betreiben, da dadurch auch die im Raum vorhandene Wärme mit der Dunstabzugshaube abgesaugt werden kann. Dies gestaltet sich jedoch im Winter anders, wenn es kalt ist, und dann die beheizte warme Luft aus dem Innenraum durch die Dunstabzugshaube nach außen entweicht. Für diesen Fall bietet sich dann an, die Dunstabzugshaube als Umlufthaube zu betreiben.Extractor hoods are known from the prior art, which can be selectively switched to operate as a recirculation or exhaust hood. This is for the reason to avoid heat loss from the inside to the outside of a housing. Thus, in such a switchable hood the possibility, for example, in the summer to operate the hood as exhaust hood, as it also the existing heat in the room can be sucked with the hood. However, this is different in winter when it is cold, and then the heated warm air escapes from the interior through the hood to the outside. In this case, then offers to operate the hood as a circulating hood.

So ist beispielsweise aus der EP 0 940 633 eine Dunstabzugshaube für einen Herd oder eine Kochstelle bekannt, die als Unterbauhaube ausgebildet ist. Die Unterbauhaube ist flach und kastenförmig ausgebildet, so dass diese beispielsweise unter einem Unterschrank eines Küchenmöbels untergebracht werden kann. In dem flach ausgelegten Gehäuse sind zwei Radialgebläse mit vertikalen Rotationsachsen parallel nebeneinander angeordnet. Die Gebläsegehäuse sind über ungefähr 1/3 ihres Umfangs offen, wobei ihre offenen Seiten einander zugewandt sind. Zwischen ihnen befinden sich vertikale Schwenkachsen für Klappen, die die Umstellung der Unterbauhaube vom Abluftbetrieb zum Umluftbetrieb oder umgekehrt bewirken.For example, from the EP 0 940 633 an extractor hood for a stove or a hotplate known, which is designed as a substructure hood. The base hood is flat and box-shaped, so that it can be accommodated, for example, under a base of a kitchen cabinet. In the flat housing two radial fans are arranged with vertical axes of rotation parallel to each other. The fan casings are open over approximately 1/3 of their circumference with their open sides facing each other. Between them are vertical swivel axes for flaps, which cause the conversion of the base hood from the exhaust air to recirculation mode or vice versa.

Als nachteilig bei dieser aus dem Stand der Technik bekannten Einrichtung zum wahlweisen Betreiben der Unterbauhaube wird es angesehen, dass die Einrichtung in ihrer Ausführung aufwendig baut, was eine komplizierte und aufwendige Mechanik sowie Montage mit sich bringt.A disadvantage of this known from the prior art device for selectively operating the substructure hood, it is considered that the device builds expensive in their execution, which brings a complicated and complex mechanics and assembly with it.

Ein ähnlicher Aufbau einer Dunstabzugshaube ist auch aus der DE 78 02 041 U1 bekannt. Dort wird durch das Schließen eines Schiebers bzw. den Einbau eines Leitblechs eine Umrüstung von einer Umlufthaube auf eine Ablufthaube möglich.A similar construction of an extractor hood is also from the DE 78 02 041 U1 known. There, by the closing of a slide or the installation of a baffle, a conversion from a circulating air hood to an exhaust hood is possible.

Die US 4 682 580 A zeigt eine Dunstabzugshaube mit einem Einsatz, der je nach Gebrauch als Umluft- oder Ablufthaube in eine bestimmte Stellung gedreht werden muss.The US 4 682 580 A shows an extractor hood with an insert that must be rotated depending on use as recirculation or exhaust hood in a certain position.

Der Erfindung stellt sich somit das Problem, eine Dunstabzugshaube für einen Herd, insbesondere eine als Unterbauhaube ausgebildete Dunstabzugshaube, derart weiterzubilden, die von ihrer Mechanik und von ihrer Montage zur wahlweisen Verwendung als Ablufthaube oder Umlufthaube her wesentlich einfacher zu handhaben ist.The invention thus raises the problem of further developing an extractor hood for a stove, in particular an extractor hood designed as a substructure hood, which is much easier to handle by its mechanism and by its mounting for selective use as an exhaust hood or recirculation hood.

Erfindungsgemäß wird dieses Problem mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention, this problem is solved by the features of patent claim 1. Advantageous embodiments and further developments of the invention will become apparent from the following subclaims.

Die mit der Erfindung erreichbaren Vorteile bestehen nun darin, dass durch einfache konstruktive Gestaltung eine Unterbauhaube als Umluft- oder als Ablufthaube betrieben werden kann. Hierzu bedarf es nur, bevor die Haube an den Unterschrank oder an die Wand montiert wird, des Umsetzens eines Schubes, um so die Funktionsänderung der Unterbauhaube vorzunehmen. Hierzu ist der gemeinsame Abluftkanal als ein an der Rückseite des Gehäuses geöffneter Schacht ausgebildet, in den ein als Schub ausgebildeter Einsatz einschiebbar ist, der vor der Montage der Unterbauhaube die Wahlmöglichkeit zulässt, entweder die Unterbauhaube als Ablufthaube oder als Umlufthaube zu betreiben. Dabei ist durch Einsetzen des Schubes, entweder von der Frontseite oder von der Rückseite her, der Abluftbetrieb bzw. Umluftbetrieb für die Unterbauhaube herstellbar. Dabei ist bei Einsatz des Schubes mit der Rückseite in den Schacht die Unterbauhaube als Ablufthaube betreibbar, wobei bei Einsetzen des Schubes mit der Frontseite in den Schacht die Unterbauhaube als Umlufthaube betrieben werden kann. Im Abluftbetrieb liegen die Abluftöffnungen im Haubenkörper und in der Unterbauhaube übereinander.The achievable with the present invention consist in the fact that a substructure hood can be operated as recirculation or exhaust hood by simple structural design. For this purpose, only before the hood is mounted on the base cabinet or on the wall, the conversion of a thrust, so as to make the change in function of the substructure hood. For this purpose, the common exhaust air duct is formed as a shaft open at the rear of the housing, in which an insert designed as a thrust insert is inserted, which allows the choice before installing the substructure hood, either to operate the substructure hood as an exhaust hood or as a recirculation hood. It can be produced by inserting the thrust, either from the front or from the back, the exhaust air operation or recirculation mode for the under hood. In this case, when using the thrust with the back in the shaft, the substructure hood operable as exhaust hood, wherein when inserting the thrust with the front side into the shaft, the substructure hood can be operated as a circulating air hood. In the exhaust air operation, the exhaust air openings are in the hood body and in the base hood on top of each other.

Nach einer besonders vorteilhaften Ausgestaltung des Schubes weist dieser eine Kastenform mit einer in der Deckfläche angeordneten Öffnung für den Abluftbetrieb auf. Der Schub als solches weist an seiner Rückseite eine für den Abluftbetrieb eine geöffnete Abluftführung auf, so dass die von den Radiallüftern erzeugten Luftströme durch die geöffnete Rückwand strömen können, bevor sie in den auf dem Gehäuse der Unterbauhaube aufgesetzten Stutzen abgeführt werden. Um einen geschlossenen Abluftkanal zu erhalten, ist der Schub mit Seitenwänden bestückt, die im eingeschobenen Zustand Teilbereiche des gemeinsamen Abluftkanals für den Abluftbetrieb bilden. Zur Vermeidung von Strömungsverwirbelungen im Schubgehäuse, ist an der Rückseite der Frontseite des Schubes ein Leitblech als Luftführung für den Abluftbetrieb angeordnet.According to a particularly advantageous embodiment of the thrust, this has a box shape with an opening arranged in the top surface for the exhaust air operation. The thrust as such has on its rear side for the exhaust air operation on an open exhaust duct, so that the air flows generated by the radial fans can flow through the open rear wall before they are discharged into the patch on the housing of the base hood nozzle. In order to obtain a closed exhaust air duct, the thrust is equipped with side walls, which form part of the common exhaust air duct for the exhaust air operation in the retracted state. To avoid Strömungsverwirbelungen in the sliding housing, a baffle is arranged as an air duct for the exhaust air operation at the back of the front of the thrust.

Für den Umluftbetrieb besteht die Frontseite des Schubes aus zwei Bogensegmenten, die im eingeschobenen Zustand des Schubes für den Umluftbetrieb den gemeinsamen Abluftkanal verschließen. Die Bogensegmente ergänzen hierbei die Wände der Abluftkanäle der Radiallüfter, so dass die gereinigte Abluft an den Innenraum wieder abgegeben werden kann. Nach einer zweckmäßigen Ausgestaltung des Schubes ist dieser mit Rasthaken versehen, die die gesicherte und die richtige Montage des Schubes in dem Schacht bereitstellen.For the recirculation mode, the front of the thrust consists of two arc segments, which close the common exhaust air channel in the inserted state of the thrust for the recirculation mode. The arc segments in this case supplement the walls of the exhaust air ducts of the radial fan, so that the cleaned exhaust air can be discharged to the interior again. After an expedient embodiment of the thrust this is provided with snap-in hooks that provide the secure and proper installation of the thrust in the shaft.

Die Figuren 1, 2 und 4 zeigen eine Dunstabzugshaube 1 für einen nicht näher dargestellten Herd oder eine Kochstelle. Die Dunstabzugshaube 1 ist hierbei als Unterbauhaube ausgelegt, die ein flach bauendes Gehäuse 2 umfasst, welches unter einem ebenfalls nicht näher dargestellten Hänge- oder Unterschrank verbaut werden kann. Wie insbesondere aus der Figuren 2 und 4 zu erkennen ist, sind in dem Gehäuse 2 zwei nebeneinander liegende Radiallüfter 3 und 4 angeordnet, deren Motor die Radiallüfter 3 und 4, gemäß dargestellter Pfeile, gegensinnig antreiben. Die Radiallüfter 3 und 4 sind hierbei in Luftführungskanälen 5 und 6 angeordnet, wobei die Luftführungskanäle 5 und 6 in einen gemeinsamen Luftführungskanal 7 zur Rückseite des Gehäuses 2 münden. Dabei ist im Bereich des gemeinsamen Luftführungskanals 7 eine Einrichtung 8 vorhanden, mit der die Dunstabzugshabe 1 wahlweise als Ablufthaube, dargestellt in den Figuren 2 und 3, oder als Umlufthaube, dargestellt in den Figuren 4 und 5, betreibbar ist.The FIGS. 1 . 2 and 4 show an extractor hood 1 for a stove or a cooker not shown. The extractor hood 1 is here designed as a substructure hood, which includes a flat housing 2, which can be installed under a hanging or lower unit, also not shown. As in particular from the Figures 2 and 4 can be seen, two adjacent radial fans 3 and 4 are arranged in the housing 2, the motor, the radial fans 3 and 4, according to arrows shown, drive in opposite directions. The radial fans 3 and 4 are in this case arranged in air ducts 5 and 6, wherein the air ducts 5 and 6 open into a common air duct 7 to the back of the housing 2. In this case, in the region of the common air duct 7, a device 8 is provided, with which the extractor hood 1 either as an exhaust hood, shown in the FIGS. 2 and 3 , or as a circulating hood, shown in the FIGS. 4 and 5 , is operable.

In der Figur 1 ist in der rückseitigen perspektivischen Darstellung der Dunstabzugshaube der gemeinsame Luftführungskanal 7 zu erkennen. In einen an der Rückseite vorhandenen geöffneten Schacht 9 ist ein als Schub 10 ausgebildeter Einsatz 11 einschiebbar, der vor der Montage der Dunstabzugshaube an eine Wand oder einen Unterschrank so positioniert wird, dass der Einsatz 11 hier die Wahlmöglichkeit zulässt, entweder die Dunstabzugshaube 1 als Ablufthaube, dargestellt in den Figuren 2 und 3, oder als Umlufthaube, dargestellt in den Figuren 4 und 5, zu betreiben. Wie insbesondere durch die Pfeildarstellung in der Figur 1 deutlich wird, ist durch Einsetzen des Schubes 10, entweder von der Frontseite 12 oder von der Rückseite 13 her, der Abluftbetrieb oder der Umluftbetrieb für die Dunstabzugshaube einstellbar. Wie in der in Figur 1 dargestellten Ansicht, wird bei Einsetzen des Schubes 10 mit seiner Rückseite in den Schacht 9 die Dunstabzugshaube 1 als Ablufthaube bereitgestellt, wie dies in den Figuren 2 und 3 gezeigt ist.In the FIG. 1 can be seen in the rear perspective view of the hood of the common air duct 7. In an existing at the back of open shaft 9 designed as a thrust 10 insert 11 is inserted, which is positioned before mounting the hood on a wall or a base cabinet so that the insert 11 here allows the choice, either the hood 1 as exhaust hood , presented in the FIGS. 2 and 3 , or as a circulating hood, shown in the characters 4 and 5 , to operate. As in particular by the arrow representation in the FIG. 1 becomes clear, by inserting the thrust 10, either from the front side 12 or from the back 13 forth, the exhaust air operation or the recirculation mode for the hood adjustable. As in the FIG. 1 shown view, when the thrust 10 is inserted with its back in the slot 9, the hood 1 as exhaust hood provided as shown in the FIGS. 2 and 3 is shown.

Wird der Schub 10 um 180° gedreht bzw. verschwenkt und wird er mit seiner Frontseite 12 in den Schacht 9 geschoben, so wird die Dunstabzugshaube 1 als Umlufthaube bereitgestellt, wie dies in den Figuren 4 und 5 gezeigt wird.If the thrust 10 is rotated or pivoted by 180 ° and it is pushed with its front side 12 in the shaft 9, the hood 1 is provided as a circulating hood, as in the FIGS. 4 and 5 will be shown.

Wie aus der Figur 1 zu erkennen ist, weist der Schub 10 eine Kastenform mit einer in der Deckfläche 14 angeordneten Öffnung 15 auf, welche mit der in der Oberseite des Gehäuses 2 vorhandenen Öffnung 16 im eingeschobenen Zustand übereinstimmt. Im Abluftbetrieb müssen die Abluftdurchmesser in der Unterhaube und im Schub 10 übereinander stehen. Auf die Öffnung 16 am Gehäuse 2 kann beispielsweise ein nicht dargestellter Stutzen angesetzt werden, an den wiederum ein Abluftrohr angesetzt werden kann, um so den angesaugten Wrasen durch ein Abluftrohr zum Außenbereich eines Gebäudes zu leiten. In der Zusammenschau der Figuren 1 und 2 wird deutlich, dass für den Abluftbetrieb der Schub 10 an der Rückseite 13 eine geöffnete Rückwand 16 aufweist, die sich, wie in der Figur 2 zu erkennen ist, über den gesamten Erstreckungsbereich des gemeinsamen Kanals 7 erstreckt. Wie weiter aus der Zusammenschau der Figuren 1 und 2 zu erkennen ist, ist der Schub 10 mit Seitenwänden 17 und 18 bestückt, die im eingeschobenen Zustand, dargestellt in der Figur 2, Teilbereiche des gemeinsamen Abluftkanals 7 für den Abluftbetrieb bilden. Um im Abluftkanal und hier insbesondere im gemeinsamen Abluftkanal 7, der im Bereich des Schubes gebildet wird, eine geringe Verwirbelung der Abluft bereitzustellen bzw. zu erzielen, ist an der Rückseite der Frontseite 12 des Schubes 10 ein Leitblech 19 für den Abluftbetrieb angeordnet, welches in der Figur 1 angedeutet zu erkennen ist.Like from the FIG. 1 it can be seen, the thrust 10 has a box shape with an opening 15 arranged in the top surface 14, which coincides with the present in the top of the housing 2 opening 16 in the inserted state. In exhaust air operation, the exhaust air diameters in the lower hood and in the thrust 10 must be superimposed. On the opening 16 on the housing 2, for example, a non-illustrated nozzle can be recognized, to which in turn an exhaust pipe can be attached so as to direct the sucked-in vapor through an exhaust pipe to the outside of a building. In the synopsis of FIGS. 1 and 2 It is clear that for the exhaust operation of the thrust 10 on the back 13 has an open rear wall 16, which, as in the FIG. 2 can be seen extending over the entire extent of the common channel 7. How further from the synopsis of FIGS. 1 and 2 can be seen, the thrust 10 is equipped with side walls 17 and 18, which in the inserted state, shown in the FIG. 2 , Form portions of the common exhaust duct 7 for the exhaust air operation. In order to provide or to achieve a low turbulence of the exhaust air in the exhaust air duct and here in particular in the common exhaust duct 7, which is formed in the region of the thrust, a baffle 19 for the exhaust air operation is arranged at the back of the front side 12 of the thrust 10, which in of the FIG. 1 indicated is to recognize.

Will man nun die Dunstabzugshaube 1, vor der Montage bzw. bevor diese in einen Unterschrank oder an eine Wand angebaut wird, im Umluftbetrieb betreiben, so wird der in der Figur 1 dargestellte Schub 10 mit der Frontseite 12 in den Schacht 9 geschoben, so dass die an der Frontseite 12 des Schubes 10 vorhandenen Bogensegmente 20 und 21 in das Schachttiefste eindringen. Die zwei Bogensegmente 20 und 21 verschließen hierbei im eingeschobenen Zustand des Schubes 10, den für den Umluftbetrieb gemeinsamen Abluftkanal 7, wie dies insbesondere in der Figur 4 zu erkennen ist. Die Bogensegmente 20 und 21 ergänzen die Wände 22 und 23 der Luftführungskanäle 5 und 6 der Radiallüfter 3 und 4, so dass diese sich strömungsergonomisch einfügen. Die gereinigte Küchenluft wird gemäß der dargestellten Pfeile wieder an den Innenraum abgegeben.Will you now the hood 1, before installation or before it is mounted in a cabinet or on a wall, operate in recirculation mode, so in the FIG. 1 shown thrust 10 is pushed with the front side 12 in the shaft 9, so that the present on the front side 12 of the thrust 10 arc segments 20 and 21 penetrate into the shaft deepest. The two arc segments 20 and 21 close here in the inserted state of the thrust 10, the common for the recirculation mode exhaust duct 7, as in particular in the FIG. 4 can be seen. The arcuate segments 20 and 21 complement the walls 22 and 23 of the air ducts 5 and 6 of the radial fans 3 and 4, so that they themselves insert flow-ergonomically. The cleaned kitchen air is returned to the interior according to the arrows shown.
