Description

Die Erfindung betrifft ein Verfahren zum Betrieb eines Raumlüftungssystems, insbesondere für Wohnräume mit einer wahlweise im Abluft- und Umluftbetrieb arbeitenden Dunstabzugshaube, die über eine Steuerungseinrichtung mit einer Lüftungseinrichtung zum Zuführen von Aussenluft in den Wohnraum zusammenwirkt.The invention relates to a method for operating a room ventilation system, in particular for living rooms with an extractor hood optionally operating in exhaust air and recirculation mode, which interacts via a control device with a ventilation device for supplying outside air into the living room.

Derartige Verfahren für Dunstabzugshauben sind bekannt und in vielen modernen Kücheneinrichtungen vorhanden, insbesondere wenn die Küche in einem Wohnraum des Gebäudes integriert ist und der entstehende Dunst sonst direkt im Wohnraum wahrnehmbar ist. Arbeitet die Abzugshaube im Abluftbetrieb, entsteht dann im Wohnraum ein Unterdruck, der bekanntlich aus verschiedenen Gründen unerwünscht ist.Such methods for extractor hoods are known and available in many modern kitchen facilities, especially if the kitchen is integrated in a living room of the building and the resulting haze is otherwise perceptible directly in the living room. If the extractor hood works in exhaust air mode, a negative pressure then arises in the living room, which is known to be undesirable for various reasons.

Um diesen Unterdruck zu kompensieren, ist es bekannt, den Wohnraum mit einer Lüftungseinrichtung auszustatten, mit welcher dem Wohnraum Aussenluft zugeführt wird.To compensate for this negative pressure, it is known to equip the living space with a ventilation device with which outside air is supplied to the living space.

Eine Anlage dieser Gattung ist in der EP-A-2 613 099 geoffenbart. Die dort beschriebene Anlage eignet sich jedoch nur für komplexe Wohnungen, die eine Vielzahl von den Luftdruck beeinflussenden Geräten beinhalten. Die für die Anlage vorgesehene Steuerung ist dementsprechend aufwendig, da sie einerseits laufend den Betriebszustand der einzelnen Geräte steuern muss und andererseits eventuell mehrere Luftdruck-Messstellen aufweisen muss, um laufend zu ermitteln, ob bzw. in welchem Bereich der Wohnung sich ein Unterdruck gebildet hat.A plant of this type is in the EP-A-2 613 099 revealed. However, the system described there is only suitable for complex apartments that contain a large number of devices that influence the air pressure. The control provided for the system is accordingly complex, since on the one hand it has to continuously control the operating state of the individual devices and on the other hand it may have to have several air pressure measuring points in order to continuously determine whether or in which area of the apartment a negative pressure has developed.

Bei einfach konstruierten Gebäuden ist eine solche Raumlüftungsanlage zu aufwendig, sowohl hinsichtlich der Installation und des Aufbaus als auch wegen ihrer komplexen Betriebsweise. Bei derartigen Gebäuden erfolgt die Lüftung in der Regel durch manuelles Öffnen und Schliessen eines Aussenfensters des Wohnraums. Dabei wird die im Küchenbereich installierte Dunstabzugshaube im Wohnraum einen Unterdruck erzeugen, solange sie im Abluftbetrieb arbeitet und die Aussenfenster und Türen des Wohnraums geschlossen sind.In the case of simply constructed buildings, such a room ventilation system is too complex, both with regard to installation and construction also because of their complex mode of operation. In buildings of this type, ventilation is usually carried out by manually opening and closing an outer window of the living room. The extractor hood installed in the kitchen area will create a negative pressure in the living room as long as it works in the extract air mode and the outside windows and doors of the living room are closed.

In der Druckschrift WO-A-2007/134829 ist eine Einrichtung für mit einem Lüfter versehene Dunstabzugshauben offenbart, welche eine im Absaugluftstrom angeordnete Umlenkklappe aufweist, die mit einem motorischen Antrieb derart steuerbar ist, dass der Absaugluftstrom entweder direkt ins Freie geführt oder über einen Aktivkohlefilter in den Absaugraum rückgeführt wird. Bei einer im Absaugraum befindlichen offenen Feuerstelle ist eine Sicherheitseinrichtung vorgesehen, die mit einer bzw. für eine Belüftungsvorrichtung, beispielsweise ein Fenster, gekoppelt ist.In the publication WO-A-2007/134829 discloses a device for extractor hoods provided with a fan, which has a deflection flap arranged in the exhaust air flow and which can be controlled by a motor drive such that the exhaust air flow is either led directly into the open or is returned to the suction space via an activated carbon filter. In the case of an open fireplace located in the suction space, a safety device is provided which is coupled to or for a ventilation device, for example a window.

Gemäss der Druckschrift DE-U-9208718 ist dargetan, dass ein funktionierender Abluftbetrieb voraussetzt, dass in den entlüfteten Raum durch anderweitige Öffnungen wieder Frischluft einströmen kann, damit kein Unterdruck entsteht. Es soll daher ein Wechsel auf Umluftbetrieb und eine Zurückschaltung auf Abluftbetrieb selbsttätig erfolgen. Dies wird dadurch erreicht, dass eine Strömungsdrossel in einem separaten Bauelement vorhanden ist. Normalerweise wird also die vom Lüfter herangeförderte Luft als Abluft durch den Mauerkasten ins Freie geleitet. Soweit sich jedoch im entlüfteten Raum ein Unterdruck gebildet hat, wird die durch den Strömungs-Druckabfall im Umluftzweig gegebene Hemmung, die im Extremfall auch als Schwelle wirken kann, überwunden und die hinter dem Gebläse gestaute Luft fliesst über den Umluftzweig, also über die Filteranlage, in den entlüfteten Raum zurück. Wird ein Fenster geöffnet und hierdurch der Unterdruck im entlüfteten Raum aufgehoben, so lenkt sich der Luftstrom automatisch wieder auf den Abluftzweig zurück.According to the publication DE-U-9208718 is shown that a functioning exhaust air operation requires that fresh air can flow back into the ventilated room through other openings, so that no negative pressure arises. There should therefore be a change to air recirculation mode and a switch back to exhaust air mode automatically. This is achieved in that a flow restrictor is provided in a separate component. Normally, the air brought in by the fan is discharged through the wall box to the outside as exhaust air. If, however, a negative pressure has formed in the vented room, the inhibition caused by the flow pressure drop in the air recirculation branch, which in extreme cases can also act as a threshold, is overcome and the air stowed behind the fan flows via the air recirculation branch, that is to say via the filter system. back into the ventilated room. If a window is opened and the negative pressure in the ventilated room is released as a result, the air flow automatically returns to the exhaust air branch.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Betrieb eines Raumlüftungssystems der eingangs genannten Art zu schaffen, das mit möglichst kleinem apparativen Aufwand die Bildung eines Unterdrucks in Wohnräumen unterbindet und die einwandfreie Funktion des Systems sicherstellt.The invention has for its object to provide a method for operating a room ventilation system of the type mentioned, which prevents the formation of a negative pressure in living spaces with the least possible equipment and ensures the proper functioning of the system.

Diese Aufgabe ist erfindungsgemäss dadurch gelöst, dass die Dunstabzugshaube automatisch einerseits beim Öffnen der Lüftungseinrichtung auf Abluftbetrieb und andererseits beim Schliessen derselben auf Umluftbetrieb schaltet.This object is achieved according to the invention in that the extractor hood automatically switches to exhaust air mode on the one hand when the ventilation device is opened and on the other hand to recirculation mode when it is closed.

Die Erfindung umfasst ein Verfahren zum Betrieb eines Raumlüftungssystems nach den Ansprüchen 1 bis 4 und ein Raumlüftungssystem nach den Ansprüchen 5 bis 9.The invention comprises a method for operating a room ventilation system according to claims 1 to 4 and a room ventilation system according to claims 5 to 9.

Damit wird erreicht, dass bei eingeschalteter Dunstabzugshaube insbesondere während dem Kochen gewährleistet ist, dass kein Unterdruck bzw. stets ein optimaler Betrieb in Bezug auf einen geringen Energieverbrauch erzielt wird.This ensures that when the extractor hood is switched on, especially during cooking, it is ensured that no negative pressure or optimal operation with regard to low energy consumption is always achieved.

Ob eine Lüftungseinrichtung gerade geöffnet bzw. geschlossen ist oder wird, kann durch die jeweilige Schalterstellung bei derselben festgestellt werden.Whether a ventilation device is currently open or closed can be determined by the respective switch position.

Die Erfindung sieht optional vor, dass bei einer Umschaltmöglichkeit der Dunstabzugshaube von Abluft- auf Umluftbetrieb die Aussenluftzufuhr der Lüftungseinrichtung entweder automatisch oder von Hand geschlossen wird. Das gilt auch beim Abschalten der Abzugshaube, wenn diese vorher auf Abluftbetrieb eingestellt war.The invention optionally provides that when the extractor hood can be switched from exhaust air to recirculation mode, the outside air supply to the ventilation device is closed either automatically or by hand. This also applies when the extractor hood is switched off if it was previously set to extract air mode.

Als Lüftungseinrichtung eignet sich auch ohne weiteres ein Lüftungsschlitz beim Fenster bzw. ein Lüftungsflügel in der Hauswand.A ventilation slot in the window or a ventilation wing in the house wall is also suitable as a ventilation device.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnung näher erläutert. Es zeigt:

Fig. 1

Fig. 2
die Anlage nach Fig. 1 und die dazugehörige Steuerungseinrichtung, schematisch dargestellt.
The invention is explained in more detail below using an exemplary embodiment with reference to the drawing. It shows:
Fig. 1
a room ventilation system according to the invention, shown spatially, and
Fig. 2
the plant after Fig. 1 and the associated control device, shown schematically.

Das in Fig. 1 dargestellte Raumlüftungssystem befindet sich in einem Wohnraum 1 vorzugsweise mit einer integrierten Kücheneinrichtung 2, welcher eine Dunstabzugshaube 3 mit einem Abluftrohr 15 zugeordnet ist. Vorteilhaft ist in dieser Dunstabzugshaube 3 ein Filterpaket integriert, durch welche die durch das Kochen mit Fettpartikeln und andern Partikeln sowie Gerüchen versehene Luft gereinigt wird.This in Fig. 1 The room ventilation system shown is located in a living room 1, preferably with an integrated kitchen device 2, to which an extractor hood 3 with an exhaust pipe 15 is assigned. In this extractor hood 3, a filter package is advantageously integrated, through which the air provided by cooking with fat particles and other particles as well as odors is cleaned.

Gemäss Fig. 2 schliesst oberhalb der Dunstabzugshaube 3 eine Einrichtung 13 an, die vorzugsweise einen oberen Auslass für das Abluftrohr 15, seitliche Auslässe 13' und schwenkbare Umleitklappen 14 zum Umleiten des Luftstroms vom Umluft- auf Abluftbetrieb aufweist. Die strichpunktiert angedeuteten Umleitklappen 14 sind je um eine Achse 14' von einer die seitlichen Auslässe 13' in eine den Auslass ins Abluftrohr 15 öffnende Stellung schwenkbar. Eine solche Einrichtung 15 ist bekannt und beispielsweise in der Druckschrift EP-A-2 290 298 beschrieben. Diese ist daher nicht nochmals in allen Einzelheiten dargetan.According to Fig. 2 connects above the extractor hood 3 to a device 13, which preferably has an upper outlet for the exhaust pipe 15, side outlets 13 'and pivotable diverter flaps 14 for diverting the air flow from the recirculating air to the exhaust air mode. The diverter flaps 14, indicated by dash-dotted lines, can each be pivoted about an axis 14 'from one of the side outlets 13' to a position which opens the outlet into the exhaust pipe 15. Such a device 15 is known and for example in the publication EP-A-2 290 298 described. It is therefore not shown in all details again.

Diese wahlweise im Abluft- bzw. Umluftbetrieb arbeitende Dunstabzugshaube 3 wirkt zweckmässigerweise über eine Steuerungseinrichtung 6 mit einer Lüftungseinrichtung 9 zum Zuführen von Aussenluft in den Wohnraum zusammen. Bei dieser Lüftungseinrichtung 9 kann es sich um ein aufklappbares oder aufschwenkbares Fenster 9', um Lüftungsflügel oder andere verschliessbare Öffnungen handeln.This extractor hood 3, which optionally works in exhaust air or recirculation mode, expediently interacts via a control device 6 with a ventilation device 9 for supplying outside air into the living space. This ventilation device 9 can be a window 9 'which can be opened or swung open, ventilation wings or other closable openings.

Beim erfindungsgemässen Verfahren wird die Dunstabzugshaube 3 automatisch einerseits beim Öffnen der Lüftungseinrichtung 9 auf Abluftbetrieb und andererseits beim Schliessen derselben auf Umluftbetrieb geschaltet.In the method according to the invention, the extractor hood 3 is automatically switched to exhaust air mode on the one hand when the ventilation device 9 is opened and, on the other hand, to recirculation mode when it is closed.

Damit ergibt sich ein optimaler Betrieb, da die in der Haube 3 gereinigte Luft wieder zurück in den Raum geführt wird, und damit insbesondere bei kalten Aussentemperaturen, bei denen die Fenster geschlossen sind, nicht unnötig warme Luft nach aussen befördert wird.This results in optimal operation, since the air cleaned in the hood 3 is led back into the room, and therefore unnecessarily warm air is not conveyed to the outside, especially at cold outside temperatures at which the windows are closed.

Ob eine Lüftungseinrichtung gerade geöffnet bzw. geschlossen wird, kann beispielsweise durch an der jeweiligen der Steuerungseinrichtung 6 zugehörigen Schalterstellung bei dem Fenster 9', der Türe, dem Lüftungsflügel oder dergleichen als Lüftungseinrichtung festgestellt werden. Bei diesem Schalter kann es sich um wenigstens einen elektrischen Kontakt handeln, welcher die (geschlossene) Stellung der Lüftungseinrichtung eindeutig detektiert. Selbstverständlich könnte dies auch anders, zum Beispiel durch einen Temperatursensor oder dergleichen realisiert sein.Whether a ventilation device is currently being opened or closed can be determined, for example, by means of the switch position associated with the control device 6 in the window 9 ', the door, the ventilation wing or the like as a ventilation device. This switch can be at least one electrical contact which clearly detects the (closed) position of the ventilation device. Of course, this could also be done differently, for example by a temperature sensor or the like.

Das erfindungsgemässe Verfahren zum Betrieb des Raumlüftungssystems arbeitet wie folgt:
Wenn das oder die Lüftungsfenster 9 geschlossen sind, arbeitet die Dunstabzugshaube 3 im Umluftbetrieb. Damit ist sichergestellt, dass im Wohnraum kein Unterdruck entsteht, da die abgesaugte und gefilterte Luft in den Raum zurückgeführt wird.The method according to the invention for operating the room ventilation system works as follows:
When the ventilation window (s) 9 are closed, the extractor hood 3 operates in recirculation mode. This ensures that there is no negative pressure in the living room, since the extracted and filtered air is returned to the room.

Bei einem Öffnen des Lüftungsfensters 9 erfolgt via diesen beim Fenster vorgesehenen Schalter automatisch ein Umstellen der von der Dunstabzugshaube 3 angesaugten Luft von Um- auf Abluftbetrieb. Dies bewirkt eine Verhinderung eines Unterdrucks im Wohnraum und es wird dabei eine Frischluftzufuhr bewirkt.When the ventilation window 9 is opened, this switch at the window automatically switches the air sucked in by the extractor hood 3 from recirculated to exhaust air mode. This prevents a negative pressure in the living room and fresh air is supplied.

Ferner kann als Variante im Rahmen der Erfindung bei der Dunstabzugshaube 3 zusätzlich ein Wahlschalter 4 vorgesehen sein, bei dem von Hand auf Umluft- bzw. Abluftbetrieb geschaltet werden kann. Die Dunstabzugshaube besitzt ausserdem einen Ein- und Ausschalter 5 sowie eine Steuerungseinrichtung 6, mit welcher der Wahlschalter 4 und der Einund Ausschalter 5 über eine Funkverbindung 7 mit dem Fensteröffner 8 eines als Lüftungsgerät wirkenden Lüftungsfensters 9 des Wohnraums 1 verbunden sind.Furthermore, as a variant within the scope of the invention, a selection switch 4 can additionally be provided in the extractor hood 3, in which a manual switch can be made to recirculation or exhaust air operation. The extractor hood also has an on and off switch 5 and a control device 6, with which the selector switch 4 and the on and off switch 5 are connected via a radio link 7 to the window opener 8 of a ventilation window 9 of the living space 1 which acts as a ventilation device.

Wird die Abzugshaube 3 vom Umluftbetrieb auf Abluftbetrieb umgeschaltet, kann ein Öffnen des Lüftungsfensters 9 automatisch erfolgen, um sicherzustellen, dass die Aussenluftzufuhr des Fensters den im Abluftbetrieb entstehenden Druckabfall in den Wohnräumen eliminiert. Das Lüftungsfenster 9 kann aber auch selbstverständlich von Hand geöffnet werden, etwa durch die für die Abzugshaube zuständige Bedienperson.If the extractor hood 3 is switched from the recirculation mode to the exhaust air mode, the ventilation window 9 can be opened automatically to ensure that the outside air supply to the window is in the exhaust mode pressure drop in the living rooms is eliminated. The ventilation window 9 can of course also be opened by hand, for example by the operator responsible for the extractor hood.

Zur Feststellung, ob eine Lüftungseinrichtung geöffnet bzw. geschlossen wird, kann das System mit einem Unterdruckmessgerät 10 versehen sein, das über die Steuereinrichtung 6 mit der Abzugshaube 3 verbunden ist.To determine whether a ventilation device is opened or closed, the system can be provided with a vacuum measuring device 10 which is connected to the extractor hood 3 via the control device 6.

Es ist ein Umschalten der Abzugshaube 3 auf Umluftbetrieb möglich, dies wenn das Lüftungsfenster 9 geschlossen wird, entweder von Hand oder aber automatisch über die Steuereinrichtung 6, die dementsprechend selbsttätig auf den Fensteröffner 8 des Lüftungsfensters 9 wirksam wird.It is possible to switch the extractor hood 3 to recirculation mode, when the ventilation window 9 is closed, either manually or automatically via the control device 6, which accordingly automatically acts on the window opener 8 of the ventilation window 9.

Die Steuerungseinrichtung 6 ist dabei so ausgelegt, dass im Normalfall, wenn nicht der Wahlschalter 4 betätigt worden ist, die abgesaugte Luft im Umluftbetrieb in den Raum zurückgeführt wird, indes beim Öffnen einer Lüftungseinrichtung 9 automatisch auf Abluftbetrieb umgeschaltet wird.The control device 6 is designed such that, in the normal case, if the selector switch 4 has not been actuated, the extracted air is returned to the room in recirculation mode, but is automatically switched to exhaust air mode when a ventilation device 9 is opened.

Falls im Wohnraum mehrere Aussenfenster vorhanden sind, ist es auch möglich, die Steuereinrichtung 6 so auszugestalten, dass die Aussenluftzufuhr durch ein im voraus gewähltes Lüftungsfenster erfolgt, oder aber dass die Zuluft dem Innenraum gleich durch mehrere Fenster des Wohnraums zugeführt wird, die synchron oder zeitversetzt über die Steuereinrichtung 6 wirksam sind.If there are several exterior windows in the living room, it is also possible to design the control device 6 so that the outside air is supplied through a ventilation window selected in advance, or that the supply air is supplied to the interior through several windows of the living room that are synchronous or delayed are effective via the control device 6.

Als Lüftungseinrichtung eignet sich auch ein Lüftungsschlitz bzw. ein Lüftungsflügel 11, der im vorliegenden Fall in der Aussenwand des Wohnraums angebracht ist. Der Lüftungsschlitz bzw. Lüftungsflügel 11 kann auch beim Fenster 9 angebracht sein. Er ist mit einem Schieber 12 oder einer Schwenkeinrichtung betätigbar, der oder die über die Steuereinrichtung 6 ähnlich wie der Fensteröffner 8 gesteuert wird.A ventilation slot or a ventilation wing 11, which in the present case is attached in the outer wall of the living space, is also suitable as a ventilation device. The ventilation slot or ventilation wing 11 can also be attached to the window 9. It can be operated with a slide 12 or a swivel device which is controlled via the control device 6 in a manner similar to the window opener 8.
