Description

Dunstabzugsvorrichtung mit erweiterten Funktionen Extractor hood with extended functions
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 an extractor device with a fan device for moving air, a sensor device for detecting a measured value with respect to the surroundings of the extractor hood and a control device for controlling the fan device on the basis of the recorded 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 remove the steam generated during cooking from the hob or from the stove or from the respective kitchen room. However, extractor hoods are also known, which are equipped with a wide variety of sensors in order to monitor the events on the stove or the hob below and to be able to draw conclusions about the current ventilation requirements from the knowledge gained using suitable electronics.
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.Measured values obtained from the extractor hood can thus allow conclusions to be drawn about the progress of the heating processes in the hob or in the cooker. These conclusions can be used to control the heating processes, so that the heating processes can be carried out in an optimized manner, for example with minimal energy, minimal time or in other respects. With the extractor hood according to the invention it is thus possible to provide extended functions and to increase living and working comfort in the kitchen and to take over safety 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 oxi- dierbare Gase, wie Wasserstoff, Kohlenmonoxid, Aliphaten oder Lösungsmitteldämpfe anspricht.Furthermore, for example from the German utility model DE-GM-77 36 725 a hood is known, in which inside or below the space spanned by the hood between the exhaust pipe and the furnace outlet at least one sensor is appealing when a predetermined concentration of decay products is exceeded. This sensor contains a gas-sensitive semiconductor element that is based on oxi- selectable gases, such as hydrogen, carbon monoxide, aliphates or solvent vapors.
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 Dunstabzugstemperaturfühlern 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.Furthermore, from the German published patent application DE 39 22 090 A1 an extractor hood for cooking stoves is known, in which a group of extractor temperature sensors is arranged in a positional assignment to the cooking area on a suction surface covering the extractor area in order to detect temperature fluctuations over the cooking areas. The same number of room temperature sensors are provided on an outside of the extractor hood to record the room temperature. Both groups of temperature sensors are linked to form an extractor and a room temperature signal. The difference signal formed from this is used for two-stage control of the extractor fan. The room sensor thus supplies a setpoint for controlling the fan.
Ferner ist aus der deutschen Offenlegungsschrift DE 30 39 246 A1 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, an extractor hood is known from German published patent application DE 30 39 246 A1, which has at least one sensor element that faces the stove surface and is responsive to moisture, haze, smoke and / or heat. In addition, this extractor hood can be equipped with an optical or acoustic warning device which can be switched on by the control device when predetermined setpoints are exceeded. With this extractor hood, the atmosphere above the respective stove can be regulated. In this case too, differential values are calculated, one of the sensors on the extractor hood providing a corresponding setpoint.
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 in homes and offices. A UV radiation sensor and a gas sensor are used together, for example to start cleaning the air immediately after lighting a cigarette in a room. If no UV radiation signal is received, but a certain gas concentration, 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. Erfindungsgemäß wird diese 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, wobei mit der Sensoreinrichtung der Sauerstoffgehalt als der Messwert erfassbar ist.The object of the present invention is to expand the function of extractor hoods. According to the invention, this object is achieved by an extractor device with a blower device for moving air, a sensor device for detecting a measured value with respect to the surroundings of the extractor hood and a control device for controlling the blower device on the basis of the measured value, the oxygen content as the measured value with the sensor device is detectable.
Ferner 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.Furthermore, the above-mentioned object is achieved by an extractor device with a blower device for moving air, a sensor device for detecting a measured value with respect to the surroundings of the extractor hood and a control device for controlling the blower device on the basis of the recorded measured value, and a climate control device for regulating the air - And / or indoor climates in the vicinity of the extractor hood.
Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous developments of the invention result from the subclaims.
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 exemplary 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 an extractor tube 2. A blower device 3, not shown, sucks off the vapors from a cooking area below the extractor hood 1 and conveys them through the extractor tube 2, filtered or unfiltered. A sensor device or a sensor 4 detects gases and vapors that rise or are drawn into the extractor hood 1. The measurement signal from 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 physikali- sehe 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 attached to the extractor pipe 2 in order to record measured values from the surroundings of the extractor hood 1. Such measured values can be physically see measured values such as temperature, pressure, light etc., or chemical measured values such as the type and concentration of gases or vapors. A climate control device 7 is controlled with the measurement signal of the second sensor 6. This gives the extractor hood 1 the additional functionality of an air conditioning system for the kitchen or for the room in which the extractor 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. Darü- berhinaus 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 tube 2. The position of the sensors is thus only indicated symbolically and can be chosen as desired on the extractor hood 1 or on the extractor tube 2, depending on the expediency. In addition, further sensors for controlling the blower device 3 or the climate control device can also be attached to the extractor hood 1 or the extractor pipe 2.
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 sensors attached to or in the extractor hood 1 or the extractor tube 2 can be used not only to control the extractor hood but also to monitor the kitchen or the entire apartment. Thus, information can be obtained not only about the processes in the hob and hob's area of influence, but also about the ambient air or the ambient conditions for controlling other devices. This increases living and working comfort as well as 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 moisture and temperature sensors with which the current climate data in the kitchen can be determined and the extractor hood can be caused 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 air connection but also a supply air connection 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. 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.The extractor hood 1 can be specially equipped with a moisture separator with which moisture can be extracted from the kitchen air. For example, a humidifier can be provided on or in the extractor hood 1 in order to increase the humidity in the room accordingly. In the same way, the extractor hood 1 can be provided with a heating or cooling device in order to regulate the temperature in the room by means of a temperature sensor. The extractor hood 1 thus has all the basic functionalities of an air conditioning system. As already mentioned, any gas sensors can be attached in or on the extractor hood. In this way, unpleasant odors can be detected depending on the concentration. By appropriately controlling the blower device 3, the kitchen or the apartment can be quickly ventilated in order to eliminate this malfunction.
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 Sauerstoffmes- signals Frischluft in den Raum gefördert werden.As already mentioned, a gas sensor 4, 6 can be, for example, an oxygen sensor for monitoring the oxygen content of the breathing air. For example, it can make sense to monitor the oxygen content in a kitchen in which a large number of people are employed. A suitable supply device, which can be integrated in an external device or in the extractor hood, can be used to convey fresh air 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, if flammable gas, such as cylinder, city or coke oven gas, occurs, 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. E- benso 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 flow direction in the chimney due to its suction effect. This can lead to increased concentrations of carbon monoxide, nitrogen oxides, smoke and the like, for example. Special sensors can be provided for this. In order to eliminate or minimize this effect of increasing the pollutant concentration, the extractor hood 1 must reduce its blower output in a suitable manner. It also makes sense that if a fire is detected in the building with such sensors, 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 Dunstabzugs- haube 1 beispielsweise über einen Warnsummer oder über eine Warnlampe verfügen, um auf eine bestehende Gefahr akustisch oder optisch hinzuweisen.In addition to regulating the blower output, the sensors can also be used to control a warning device on the extractor hood 1. So the extractor hood hood 1 have, for example, a warning buzzer or a warning lamp to indicate acoustically or optically to an existing danger.
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 Fernüberwachung oder Fernsteuerung im Bereich der Dunstabzugshaube zu gewährleisten.It also makes sense if the extractor hood has a connection to an existing house electronics system in order to trigger the shutdown or activation of relevant house appliances in the event of danger. Likewise, there can be a connection to remote data connections in order to ensure remote monitoring or remote control in the area of the extractor 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, there has always been talk of an extractor hood as an extractor device. However, the extractor device can also be designed as a suction device integrated into the work surface or adjacent wall.
