Description

Die vorliegende Erfindung betrifft eine Dunstabzugsvorrichtung mit einer Gebläseeinrichtung zum Bewegen von Luft, einer Sensoreinrichtung zum Erfassen eines Messwertes bezüglich der Umgebung der Dunstabzugshaube und einer Steuereinrichtung zur Steuerung der Gebläseeinrichtung auf der Grundlage des erfassten Messwertes.The present invention relates to a fume extraction device with a blower device for moving air, a sensor device for detecting a measured value with respect to the surroundings of the fume hood and a control device for controlling the blower device on the basis of the detected measured value.

Dunstabzugshauben dienen in der Regel dazu, die beim Kochen entstehenden Dünste von der Kochmulde beziehungsweise vom Herd oder aber auch aus dem jeweiligen Küchenraum abzuleiten. Es sind aber auch Dunstabzugshauben bekannt, die mit vielerlei Sensoren ausgestattet sind, um die Ereignisse auf dem darunter angeordneten Herd beziehungsweise der Kochmulde zu überwachen und mit Hilfe einer geeigneten Elektronik aus den gewonnenen Erkenntnissen auf den aktuellen Lüftungsbedarf schließen zu können.Extractor hoods are usually used to derive the steam produced during cooking from the hob or from the stove or even from the respective kitchen space. But there are also known hoods, which are equipped with many sensors to monitor the events on the underneath arranged hearth or the cooktop and to close with the help of suitable electronics from the knowledge gained on the current ventilation needs.

So können Messwerte, die an der Dunstabzugshaube gewonnen werden, Rückschlüsse auf den Fortschritt der Erwärmungsvorgänge der Kochmulde beziehungsweise im Herd erlauben. Diese Rückschlüsse können zur Kontrolle der Erwärmungsvorgänge genutzt werden, so dass die Erwärmungsvorgänge beispielsweise mit minimaler Energie, minimaler Zeit oder nach anderen Gesichtspunkten optimiert durchgeführt werden können. Mit der erfindungsgemäßen Dunstabzugshaube ist es somit möglich, erweiterte Funktionen bereitzustellen und den Wohn- und Arbeitkomfort in der Küche zu erhöhen sowie Sicherheitsfunktionen zu übernehmen.Thus, measured values that are obtained at the hood, allow conclusions about the progress of the heating processes of the hob or in the stove. These conclusions can be used to control the heating operations, so that the heating operations can be performed optimally, for example, with minimum energy, minimum time or other considerations. With the extractor hood according to the invention, it is thus possible to provide advanced features and to increase the living and working comfort in the kitchen and to take over security functions.

Weiterhin ist beispielsweise aus dem deutschen Gebrauchsmuster DE-GM-77 36 725 eine Abzugshaube bekannt, bei der innerhalb oder unterhalb des von der Abzugshaube aufgespannten Raumes zwischen Abzugsrohr und Ofenaustritt wenigstens ein bei Überschreitung einer festgelegten Konzentration von Zerfallsprodukten ansprechender Fühler angebracht ist. Dieser Fühler enthält ein gasempfindliches Halbleiterelement, das auf oxidierbare Gase, wie Wasserstoff, Kohlenmonoxid, Aliphaten oder Lösungsmitteldämpfe anspricht.Furthermore, for example, from the German utility model DE-GM-77 36 725 a fume hood is known in which is mounted inside or below the space defined by the hood space between the exhaust pipe and furnace outlet at least one responsive when exceeding a predetermined concentration of decay products sensor. This probe contains a gas-sensitive semiconductor element that is oxidizable Gases such as hydrogen, carbon monoxide, aliphatics or solvent vapors responds.

Darüberhinaus ist aus der deutschen Offenlegungsschrift DE 39 22 090 A1 eine Dunstabzugshaube für Kochherde bekannt, bei der an einer den Dunstabzugsbereich überdeckenden Ansaugfläche eine Gruppe von Dunstabzugstemperaturfühlem in lagemäßiger Zuordnung zu der Kochestelle angeordnet ist, um Temperaturschwankungen über den Kochstellen zu erfassen. An eine Außenseite der Dunstabzugshaube sind ebenso viele Raumtemperaturfühler zum Erfassen der Raumtemperatur vorgesehen. Beide Gruppen von Temperaturfühlern sind zur Bildung eines Dunstabzug- und eines Raumtemperatursignals verknüpft. Das aus diesen gebildete Differenzsignal wird zur zweistufigen Steuerung des Abzugs-Ventilators genutzt. Der Raumsensor liefert damit für die Steuerung des Ventilators einen Sollwert.Moreover, from the German patent application DE 39 22 090 A1 an extractor hood for cookers is known in which at a the extractor hood covering the suction area a group of extractor temperature sensor is arranged in positional association with the cooking area to detect temperature fluctuations over the cooking zones. On the outside of the extractor hood as many room temperature sensors are provided for detecting the room temperature. Both groups of temperature sensors are linked to form a extractor and a room temperature signal. The difference signal formed from these is used for two-stage control of the trigger fan. The room sensor thus provides a setpoint for the control of the fan.

Ferner ist aus der deutschen Offenlegungsschrift DE 30 39 246 A1 (oberbegriff von Anspruch 1) eine Dunstabzugshaube bekannt, die wenigstens ein der Herdoberfläche zugewandtes auf Feuchtigkeit, Dunst, Rauch und/oder Wärme ansprechendes Sensorelement besitzt. Außerdem kann diese Dunstabzugshaube mit einer optischen oder akustischen Warneinrichtung ausgerüstet sein, die bei Überschreitung von vorgegebenen Sollwerten seitens der Steuereinrichtung eingeschaltet werden kann. Mit dieser Dunstabzugshaube läßt sich die Atmosphäre über dem jeweiligen Herd regulieren. Auch in diesem Fall werden Differenzwerte berechnet, wobei einer der Sensoren an der Dunstabzugshaube jeweils einen entsprechenden Sollwert liefert.Furthermore, from the German patent application DE 30 39 246 A1 (preamble of claim 1) a hood is known, which has at least one of the stove surface facing on moisture, vapor, smoke and / or heat responsive sensor element. In addition, this hood can be equipped with an optical or audible warning device that can be turned on when exceeded by predetermined setpoints by the controller. With this cooker hood, the atmosphere can be regulated over the respective stove. Also in this case, difference values are calculated, with one of the sensors on the extractor hood in each case supplying a corresponding desired value.

Schließlich ist aus der Offenlegungsschrift DE 37 28 308 A1 ein Luftreinigungsgerät bekannt, das zur Verwendung in Wohnhäusern und Büros dient. Ein UV-Strahlen-Sensor und ein Gassensor werden gemeinsam verwendet, um beispielsweise nach dem Anzünden einer Zigarette in einem Raum sofort das Reinigen der Luft zu beginnen. Falls kein UV-Strahlen-Signal empfangen wird, aber eine bestimmte Gaskonzentration, so wird der Reinigungsbetrieb ebenfalls ausgelöst. Dabei wird die Luft durch geeignete Filter gereinigt.Finally, from the published patent application DE 37 28 308 A1 an air cleaning device is known, which is used for residential buildings and offices. A UV-ray sensor and a gas sensor are used in common, for example, to start immediately after the lighting of a cigarette in a room, the cleaning of the air. If no UV radiation signal is received, but a certain gas concentration, then the cleaning operation is also triggered. The air is cleaned by suitable filters.

Die Aufgabe der vorliegenden Erfindung besteht darin, die Funktion von Dunstabzugshauben zu erweitern. Es wird die oben genannte Aufgabe gelöst durch eine Dunstabzugsvorrichtung mit einer Gebläseeinrichtung zum Bewegen von Luft, einer Sensoreinrichtung zum Erfassen eines Messwerts bezüglich der Umgebung der Dunstabzugshaube und einer Steuereinrichtung zur Steuerung der Gebläseeinrichtung auf der Grundlage des erfassten Messwerts, sowie einer Klimaregeleinrichtung zur Regelung des Luft- und/oder Raumklimas in der Umgebung der Dunstabzugshaube.The object of the present invention is to expand the function of cooker hoods. The above object is achieved by an extractor device with a fan device for moving air, a sensor device for detecting a measured value with respect to the environment of the extractor hood and a control device for controlling the fan device on the basis of the detected measured value, and a climate control device for controlling the air - and / or indoor climate in the vicinity of the hood.

Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous developments of the invention will become apparent from the dependent claims.

Die Erfindung wird nun anhand der beigefügten Zeichnung näher erläutert, die schematisch eine erfindungsgemäße Dunstabzugshaube zeigt.The invention will now be explained in more detail with reference to the accompanying drawing, which schematically shows an extractor hood according to the invention.

Die nachfolgend erläuterten Ausführungsbeispiele sind bevorzugte Ausführungsformen der vorliegenden Erfindung.The embodiments explained below are preferred embodiments of the present invention.

Die Figur zeigt eine Dunstabzugshaube 1 mit einem Dunstabzugsrohr 2. Eine nicht dargestellte Gebläseeinrichtung 3 saugt die unterhalb der Dunstabzugshaube 1 entstehenden Dämpfe einer Kochstelle ab und befördert sie durch das Dunstabzugsrohr 2 gefiltert oder ungefiltert ab. Eine Senoreinrichtung beziehungsweise ein Sensor 4 erfasst Gase und Dämpfe, die in die Dunstabzugshaube 1 steigen beziehungsweise gesogen werden. Das Messignal des Sensors 4 wird in einer Steuereinrichtung 5 ausgewertet. Nach bestimmten Vorgaben steuert die Steuereinrichtung 5 die Gebläseeinrichtung 3 auf der Grundlage des von dem Sensor 4 erhaltenen Messwertes an.The figure shows an extractor hood 1 with a fume extractor tube 2. A blower device 3, not shown, sucks the fumes of a cooking point below the extractor hood 1 and conveys them filtered or unfiltered through the extractor tube 2. A sensor device or a sensor 4 detects gases and vapors which rise or are sucked into the extractor hood 1. The measuring signal of the sensor 4 is evaluated in a control device 5. According to certain specifications, the control device 5 controls the blower device 3 on the basis of the measured value obtained from the sensor 4.

An dem Dunstabzugsrohr 2 ist ein zweiter Sensor 6 angebracht, um Messwerte aus der Umgebung der Dunstabzugshaube 1 zu erfassen. Derartige Messwerte können physikalische Messwerte, wie Temperatur, Druck, Licht etc., oder auch chemische Messwerte wie Art und Konzentration von Gasen oder Dämpfen sein. Mit dem Messignal des zweiten Sensors 6 wird eine Klimaregeleinrichtung 7 angesteuert. Damit erhält die Dunstabzugshaube 1 die zusätzliche Funktionalität einer Klimaanlage für die Küche beziehungsweise für den Raum, in dem sich die Dunstabzugshaube befindet.A second sensor 6 is mounted on the extractor pipe 2 in order to record measured values from the surroundings of the extractor hood 1. Such measurements can be physical Measurements, such as temperature, pressure, light, etc., or even chemical measurements such as the type and concentration of gases or vapors. With the measurement signal of the second sensor 6, a climate control device 7 is driven. Thus, the hood 1 receives the additional functionality of an air conditioner for the kitchen or for the room in which the hood is located.

In der Darstellung sind die Sensoren 4 und 6 am unteren Ende der Dunstabzugshaube 1 beziehungsweise am Dunstabzugsrohr 2 angebracht. Die Lage der Sensoren ist damit nur symbolisch angedeutet und kann entsprechend der Zweckmäßigkeit beliebig an der Dunstabzugshaube 1 beziehungsweise am Dunstabzugsrohr 2 gewählt werden. Darüberhinaus können auch weitere Sensoren zur Steuerung der Gebläseeinrichtung 3 beziehungsweise der Klimaregeleinrichtung an der Dunstabzugshaube 1 beziehungsweise dem Dunstabzugsrohr 2 angebracht werden.In the illustration, the sensors 4 and 6 are attached to the lower end of the extractor hood 1 or to the extractor pipe 2. The position of the sensors is thus only indicated symbolically and can be selected arbitrarily on the extractor hood 1 or on the extractor tube 2 according to the expediency. In addition, other sensors for controlling the fan device 3 or the climate control device to the extractor hood 1 and the extractor tube 2 can be attached.

Diese an oder in der Dunstabzugshaube 1 beziehungsweise dem Dunstabzugsrohr 2 angebrachten Sensoren lassen sich nicht nur zur Steuerung der Dunstabzugshaube sondern auch zur Überwachung der Küche beziehungsweise der gesamten Wohnung einsetzen. Somit können Informationen nicht nur über die Vorgänge im Einflußbereich von Kochmulde und Herd, sondern auch über die Umgebungsluft beziehungsweise die Umgebungsbedingungen zur Steuerung auch anderer Geräte gewonnen werden. Damit läßt sich der Wohn- und Arbeitskomfort sowie die Sicherheit in der Küche beziehungsweise im gesamten Haushalt erhöhen.These attached to or in the hood 1 and the extractor tube 2 sensors can be used not only to control the hood but also to monitor the kitchen or the entire apartment. Thus, information can be obtained not only about the processes in the sphere of influence of cooktop and stove, but also on the ambient air or the environmental conditions for the control of other devices. This can increase the living and working comfort and safety in the kitchen or in the entire household.

Speziell kann eine Dunstabzugshaube 1 mit einem oder mehreren Feuchtigkeits- und Temperatursensoren ausgestattet sein, mit denen die aktuell vorliegenden Klimadaten in der Küche festgestellt werden können und die Dunstabzugshaube dazu veranlasst werden kann, das Klima in der Küche entsprechend zu regulieren. Die Feuchtigkeit und die Temperatur in der Küche lassen sich über einen Luftanschluß zur Außenwelt beeinflussen, wobei nicht nur ein Abluft- sondern auch ein Zuluftanschluß vorgesehen sein sollte.Specifically, an extractor hood 1 can be equipped with one or more humidity and temperature sensors, with which the currently available climate data in the kitchen can be determined and the hood can be made to regulate the climate in the kitchen accordingly. The humidity and the temperature in the kitchen can be influenced via an air connection to the outside world, whereby not only an exhaust but also a Zuluftanschluß should be provided.

Die Dunstabzugshaube 1 kann speziell mit einem Feuchtigkeitsabscheider ausgestattet werden, mit dem der Küchenluft Feuchtigkeit entzogen werden kann. So kann ein Befeuchter an oder in der Dunstabzugshaube 1 vorgesehen sein, um die Feuchtigkeit im Raum entsprechend zu erhöhen.The extractor hood 1 can be specially equipped with a moisture separator, with the kitchen air moisture can be withdrawn. Thus, a humidifier may be provided on or in the hood 1 to increase the humidity in the room accordingly.

In gleicher Weise kann die Dunstabzugshaube 1 mit einer Heiz- oder Kühleinrichtung versehen sein, um mittels eines Temperatursensors die Temperatur im Raum zu regeln. Damit besitzt die Dunstabzugshaube 1 sämtliche Grundfunktionalitäten einer Klimaanlage. Wie bereits erwähnt können in oder an der Dunstabzugshaube beliebige Gassensoren angebracht werden. Dadurch können störende Gerüche unter Umständen konzentrationsabhängig erfasst werden. Durch entsprechende Ansteuerung der Gebläseeinrichtung 3 kann die Küche beziehungsweise die Wohnung rasch gelüftet werden, um diese Störung zu beseitigen.In the same way, the extractor hood 1 may be provided with a heating or cooling device to regulate the temperature in the room by means of a temperature sensor. Thus, the hood 1 has all the basic functionality of an air conditioner. As already mentioned, any gas sensors can be mounted in or on the extractor hood. As a result, disturbing odors may be detected in a concentration-dependent manner. By appropriate control of the fan 3, the kitchen or the apartment can be quickly ventilated to eliminate this disorder.

Ein Gassensor 4, 6 kann, wie bereits erwähnt, beispielsweise ein Sauerstoffsensor zur Überwachung des Sauerstoffgehaltes der Atemluft sein. So kann es beispielsweise sinnvoll sein, den Sauerstoffgehalt in einer Küche zu überwachen, in der sehr viele Personen beschäftigt sind. Durch eine geeignete Zufuhreinrichtung, die in ein externes Gerät oder in die Dunstabzugshaube integriert sein kann, kann auf der Basis des Sauerstoffmessignals Frischluft in den Raum gefördert werden.As already mentioned, a gas sensor 4, 6 may be, for example, an oxygen sensor for monitoring the oxygen content of the respiratory air. For example, it may be useful to monitor the oxygen content in a kitchen, where a large number of people are employed. By means of a suitable supply device, which can be integrated in an external device or in the extractor hood, fresh air can be conveyed into the room on the basis of the oxygen measurement signal.

Mit Hilfe von Gassensoren kann die Atemluft in der Küche auch hinsichtlich Schadstoffkonzentrationen überwacht werden. So kann beispielsweise bei Auftreten von brennbarem Gas, wie Flaschen-, Stadt- oder Kokereigas, die Lüftung maximiert werden, um Vergiftungen vorzubeugen.With the help of gas sensors, the breathing air in the kitchen can also be monitored for pollutant concentrations. For example, when flammable gas, such as bottled, city or coke oven gas, ventilation can be maximized to prevent poisoning.

In Räumen mit Kaminanschlüssen kann eine Dunstabzugshaube auf Grund ihrer Sogwirkung die Strömungsrichtung in dem Kamin umkehren. Dadurch kann es beispielsweise zu erhöhten Konzentrationen von Kohlenmonoxid, Stickoxiden, Rauch und dergleichen kommen. Hierfür können besondere Sensoren vorgesehen sein. Um diesen Effekt der Erhöhung der Schadstoffkonzentration auszuschalten beziehungsweise zu minimieren muss die Dunstabzugshaube 1 ihre Gebläseleistung in geeigneter Weise reduzieren. Ebenso ist es sinnvoll, dass, falls mit derartigen Sensoren ein Brand im Gebäude detektiert wurde, die Lüftung sofort abgeschaltet wird.In rooms with chimney connections, an extractor hood can reverse the direction of flow in the chimney due to its suction effect. This may result, for example, in increased concentrations of carbon monoxide, nitrogen oxides, smoke and the like. For this purpose, special sensors can be provided. In order to eliminate or minimize this effect of increasing the pollutant concentration, the extractor hood 1 must reduce its fan power in a suitable manner. Likewise, it makes sense that, if with such sensors a fire was detected in the building, the ventilation is switched off immediately.

Neben der Regulierung der Gebläseleistung können die Sensoren auch zur Steuerung einer Warneinrichtung an der Dunstabzugshaube 1 dienen. So kann die Dunstabzugshaube 1 beispielsweise über einen Warnsummer oder über eine Warnlampe verfügen, um auf eine bestehende Gefahr akustisch oder optisch hinzuweisen.In addition to the regulation of the blower power, the sensors can also be used to control a warning device on the extractor hood 1. So can the hood 1, for example, have a warning buzzer or a warning lamp to indicate an existing hazard acoustically or visually.

Weiterhin ist es sinnvoll, wenn die Dunstabzugshaube über eine Verbindung zu einem vorhandenen Hauselektroniksystem verfügt, um dort im Gefahrenfall die Abschaltung beziehungsweise die Ansteuerung relevanter Hausgeräte auszulösen. Ebenso kann ein Anschluß zu Datenfernverbindungen gegeben sein, um eine Femüberwachung oder Fernsteuerung im Bereich der Dunstabzugshaube zu gewährleisten.Furthermore, it makes sense if the hood has a connection to an existing home electronics system, there to trigger in the event of danger, the shutdown or the control of relevant home appliances. Likewise, a connection to remote data connections can be provided to ensure a remote monitoring or remote control in the range of the hood.

Im Zusammenhang mit den erfindungsgemäßen Ausführungsformen wurde stets von einer Dunstabzugshaube als Dunstabzugsvorrichtung gesprochen. Die Dunstabzugsvorrichtung kann aber auch als eine in die Arbeitsfläche oder angrenzende Wand integrierte Absaugeinrichtung ausgestaltet sein.In connection with the embodiments according to the invention was always spoken of a cooker hood as extractor device. However, the extractor device can also be designed as an integrated into the work surface or adjacent wall suction device.
