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 spaces with a selectively working in the exhaust and recirculation mode extractor hood, which cooperates 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 cooker hoods are known and present in many modern kitchen appliances, especially when the kitchen is integrated in a living space of the building and the resulting haze is otherwise directly in the living room perceptible. If the fume hood operates in the exhaust air mode, then a negative pressure arises in the living space, 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 room with a ventilation device with which the living space is supplied outside air.

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 genus is in the EP-A-2 613 099 revealed. However, the plant described there is only suitable for complex apartments that contain a variety of air pressure influencing devices. The control provided for the system is correspondingly expensive, since on the one hand it constantly has to control the operating state of the individual devices and, on the other hand, it may need to have a plurality of air pressure measuring points in order to continuously determine whether or in which region of the flat a negative pressure has formed.

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.For simply constructed buildings such a ventilation system is too expensive, both in terms of installation and construction as well as because of their complex operation. In such buildings, the ventilation is usually done by manually opening and closing an exterior window of the living room. In the kitchen area, the extractor hood will create a negative pressure in the living room, as long as it is working in the exhaust air mode and the outer windows and doors of the living space are closed.

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 above, which prevents the formation of a negative pressure in living spaces with the least possible expenditure on equipment and ensures proper operation 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 automatically switches on the one hand when opening the ventilation device on exhaust air operation and on the other hand when closing the same on recirculation mode.

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 hood is switched on, especially during cooking, it is ensured that no negative pressure or always optimal operation with regard to low energy consumption is 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 or is, can be determined by the respective switch position at the same.

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.Optionally, the invention provides that when the extractor hood is switched from exhaust air to recirculation mode, the outside air supply of the ventilation unit is closed either automatically or manually. This also applies when the hood is switched off, if it had previously been set to exhaust air mode.

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

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

Fig. 1
eine erfindungsgemässe Raumlüftungsanlage, räumlich dargestellt, und
Fig. 2
die Anlage nach Fig. 1 und die dazugehörige Steuerungseinrichtung, schematisch dargestellt.
The invention will be explained in more detail with reference to an embodiment with reference to the drawing. It shows:
Fig. 1
an inventive room ventilation system, 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 Room ventilation system shown is located in a living room 1 preferably with an integrated kitchen device 2, which is associated with a hood 3 with an exhaust pipe 15. Advantageously, a filter pack is integrated in this extractor hood 3, through which the air provided by cooking with fat particles and other particles and 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 closes above the hood 3, a device 13, which preferably has an upper outlet for the exhaust pipe 15, side outlets 13 'and pivotable Umleitklappen 14 for redirecting the air flow from the recirculation to exhaust air operation. The dash-dotted lines indicated Umleitklappen 14 are each about an axis 14 'of one of the lateral outlets 13' in an outlet into the exhaust pipe 15 opening position pivotally. Such a device 15 is known and for example in the document EP-A-2 290 298 described. This is therefore not shown again in full detail.

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 optionally in the exhaust air or recirculation mode working extractor hood 3 expediently acts together via a control device 6 with a ventilation device 9 for supplying outside air into the living room. This ventilation device 9 may be a hinged or swing-open window 9 ', ventilation leaves 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 operation on the one hand when the ventilation device 9 is opened and, on the other hand, when it is closed, to the recirculation mode.

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 purified air in the hood 3 is guided back into the room, and thus not unnecessarily warm air is transported to the outside, especially in cold outdoor 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 being opened or closed can be determined, for example, by means of the control device 6 associated switch position in the window 9 ', the door, the ventilation wing or the like as a ventilation device. This switch may be at least one electrical contact which clearly detects the (closed) position of the ventilation device. Of course, this could also be realized 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 inventive method for operating the room ventilation system works as follows:
  • When the ventilation window or windows 9 are closed, the extractor hood 3 operates in recirculation mode. This ensures that there is no negative pressure in the living space, as 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 provided at the window automatically converts the air taken in by the extractor hood 3 from the ambient air to the exhaust air mode. This causes a prevention of negative pressure in the living room and it will cause a supply of fresh air.

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 in the context of the invention in the extractor hood 3 in addition a selector switch 4 may be provided in which can be switched by hand on recirculation or exhaust air operation. The extractor hood also has an on-off switch 5 and a control device 6, with which the selector switch 4 and the on-off switch 5 are connected via a radio link 7 with the window opener 8 acting as a ventilation device ventilation window 9 of the living room 1.

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 recirculation mode to exhaust air mode, the ventilation window 9 can be opened automatically to ensure that the outside air supply of the window is in the exhaust air mode resulting pressure drop in the living spaces eliminated. The ventilation window 9 can also be opened by hand, of course, for example, by the responsible for the hood operator.

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 may be provided with a vacuum gauge 10, which is connected via the control device 6 with the hood 3.

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 a switching of the hood 3 on recirculation mode possible, this when the ventilation window 9 is closed, either manually or automatically via the control device 6, which accordingly is automatically effective 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 so that in the normal case, if not the selector switch 4 has been actuated, the extracted air is recirculated in the recirculation mode in the room, while 9 is automatically switched to exhaust air operation when opening a ventilation device.

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 external windows in the living space, it is also possible to design the control device 6 in such a way that the outside air supply takes place through a ventilation window selected in advance, or else that the supply air is supplied to the interior through several windows of the living space, synchronously or with a time delay 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.As a ventilation device is also a ventilation slot or a ventilation wing 11, which is mounted in the present case in the outer wall of the living room. The ventilation slot or ventilation wing 11 may also be attached to the window 9. It is operable with a slider 12 or a pivoting device, which is controlled via the control device 6 similar to the window opener 8.
