Art. Furthermore The invention relates to a method for operating an interior filter.
Aus dem Stand der Technik bekannte Innenraumfilter für Kraftfahrzeuge weisen neben einer oder mehrerer Vliesschichten zum Zurückhalten von Feststoffpartikeln eine Aktivkohleschicht auf, welche dem Beseitigen von gasförmigen Substanzen wie beispielsweise Benzol, Toulol oder Ozon dient. Neben diesen schädlichen, gasförmigen Substanzen kann die Aktivkohleschicht den Innenraum des Kraftfahrzeugs auch vor unangenehmen Gerüchen schützen. Jedoch können aus dem Stand der Technik bekannte Innenraumfilter für Kraftfahrzeuge nicht jeden Geruch zurückhalten bzw. beseitigen, da ein Luftwiderstand des Innenraumfilters immer auch einen gewissen Frischluftdurchsatz ermöglichen muss.Out known in the art cabin filters for motor vehicles have in addition one or more nonwoven layers for retaining solid particles an activated carbon layer, which is the removal of gaseous substances such as benzene, toulol or ozone. Beside these harmful, gaseous Substances, the activated carbon layer, the interior of the motor vehicle also against unpleasant odors protect. However, you can known from the prior art cabin filters for motor vehicles do not hold back any smell or eliminate, since an air resistance of the cabin air filter always also have to allow a certain fresh air flow.
Aufgabe der vorliegenden Erfindung ist es, einen Innenraumfilter bzw. ein Verfahren zum Betreiben eines Innenraumfilters zu schaffen, welcher bzw. welches zu einem verbesserten Innenraumklima beiträgt.task The present invention is a cabin filter or a To provide method for operating an interior filter, which or which contributes to an improved indoor climate.
Die Aufgabe wird erfindungsgemäß durch einen Innenraumfilter mit den Merkmalen der Patentansprüche 1 und 6, sowie durch ein Verfahren mit den Merkmalen der Patentansprüche 8 und 9 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den jeweiligs abhängigen Patentansprüchen angegeben.The Task is achieved by a cabin filter with the features of claims 1 and 6, as well as by a method having the features of claims 8 and 9 solved. advantageous Embodiments with appropriate and non-trivial Further developments of the invention are specified in the respective dependent claims.
Bei dem erfindungsgemäßen Innenraumfilter, insbesondere für ein Kraftfahrzeug, mit mindestens einem Partikelfiltermedium und/oder mindestens einem Filtermedium zum Beseitigen von gasförmigen Substanzen ist vorgesehen, dass das mindestens eine Partikelfiltermedium und/oder das mindestens eine Filtermedium zum Beseitigen von gasförmigen Substanzen mit wenigstens einer bei Raumtemperatur flüchtigen Substanz beaufschlagt ist. So kann die bei Raumtemperatur flüchtige Substanz zu einem verbesserten Innenraumklima beitragen, indem sich diese Substanz beim Betreiben des Innenraumfilters von diesem verflüchtigt und in den Innenraum, insbesondere des Kraftfahrzeugs, gelangt.at the cabin filter according to the invention, especially for a motor vehicle, with at least one particulate filter medium and / or at least one filter medium for removing gaseous substances it is provided that the at least one particulate filter medium and / or the at least one filter medium for removing gaseous substances subjected to at least one volatile at room temperature substance is. Thus, the volatile at room temperature substance to an improved Indoor climate contribute by putting this substance in operation of the cabin air filter of this volatilizes and into the interior, in particular of the motor vehicle, passes.
In einer vorteilhaften Ausgestaltung der Erfindung umfasst die wenigstens eine bei Raumtemperatur flüchtige Substanz einen Riechstoff. Dadurch ist es ermöglicht, den Riechstoff Gerüche überdecken zu lassen, welche durch den Innenraumfilter nicht vollständig zurückhaltbar sind. So ist durch den Riechstoff dafür gesorgt, dass das Innenraumklima insbesondere des Kraftfahrzeugs durch einen angenehmen Geruch des Riechstoffs verbessert ist.In an advantageous embodiment of the invention comprises at least a volatile at room temperature Substance a fragrance. This allows the perfume to cover odors to leave, which is not completely restrained by the cabin air filter are. Thus, the fragrance ensures that the interior climate in particular of the motor vehicle by a pleasant smell of the fragrance is improved.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung umfasst die wenigstens eine bei Raumtemperatur flüchtige Substanz Sauerstoff. So kann der Innenraumfilter Sauerstoff abgeben und so zu einem verbesserten, weil sauerstoffreicheren Innenraumklima beitragen.In a further advantageous embodiment of the invention the at least one volatile at room temperature substance oxygen. Thus, the cabin air filter can release oxygen and so to an improved, because oxygen-enriched indoor climate contribute.
Des Weiteren ist es von Vorteil, wenn zumindest ein Behältnis zum Bevorraten der bei Raumtemperatur flüchtigen Substanz sowie eine Dosiereinrichtung zum Beaufschlagen des Innenraumfilters mit der in dem Behältnis bevorrateten Substanz vorgesehen sind. So kann bei nachlassender Wirkung des Innenraumfilters erneut mit der bei Raumtemperatur flüchtigen Substanz beaufschlagt werden. Wenn also durch den Riechstoff eine nur noch eingeschränkte Überdeckung nicht vollständig herausgefilterter Gerüche ermöglicht ist, kann dem Partikelfiltermedium, welches als Mikrofaservlies ausgebildet sein kann und/oder dem Filtermedium zum Beseitigen von gasförmigen Substanzen, welches beispielsweise in Form von Aktivkohlepartikeln vorliegt, Riechstoff zudosiert werden.Of Furthermore, it is advantageous if at least one container for Preserve the volatile at room temperature substance and a Dosing device for applying the interior filter with the in the container stockpiled substance are provided. So can with decreasing Effect of the interior filter again with the volatile at room temperature Substance be charged. So if by the fragrance one only limited coverage not completely filtered out odors allows is, the particulate filter medium, which as a microfiber fleece may be formed and / or the filter medium for eliminating gaseous Substances which, for example, in the form of activated carbon particles is present, perfume are added.
Gemäß einem weiteren Aspekt der Erfindung ist einem Innenraumfilter, insbesondere für ein Kraftfahrzeug, welcher mindestens ein Filtermedium zum Beseitigen von gasförmigen Substanzen aufweist, ein Ozonsensor zugeordnet, mittels welchem ein Gehalt an Ozon in einem Innenraum, insbesondere des Kraftfahrzeugs, feststellbar ist. Dadurch ist es ermöglicht, bei einem bestimmten, Fahrzeuginsassen unzuträglichen Gehalt an Ozon in dem Innenraum den Innenraumfilter gezielt von der Innenraumluft durchströmen zu lassen. Hierbei wird durch das Filtermedium zum Beseitigen von gasförmigen Substanzen der Gehalt an Ozon in der Innenraumluft vermindert und so zu einem verbesserten Innenraumklima beigetragen.According to one Another aspect of the invention is a cabin filter, in particular for a motor vehicle, which at least one filter medium for removing gaseous substances associated with an ozone sensor, by means of which a content ozone in an interior, in particular of the motor vehicle, detectable is. This makes it possible at a certain vehicle occupant, harmful ozone content in the Interior to let the cabin air filter selectively flow through the indoor air. This is done by the filter medium for removing gaseous substances the content of ozone in the indoor air decreases and so on contributed to improved indoor climate.
In einer vorteilhaften Ausgestaltung der Erfindung ist eine Regeleinrichtung vorgesehen, mittels welcher in Abhängigkeit von einem Signal des Ozonsensors ein Umluftbetrieb in dem Innenraum, insbesondere des Kraftfahrzeugs, regelbar ist. So ist es ermöglicht, dass bei Überschreiten eines definierten Schwellenwertes des Gehalts an Ozon in dem Innenraum ein Umluftbetrieb zum Reduzieren des Gehaltes an Ozon führt.In An advantageous embodiment of the invention is a control device provided by means of which in response to a signal of Ozone sensor recirculation mode in the interior, in particular the Motor vehicle, is adjustable. So it is possible that when crossing a defined threshold of the content of ozone in the interior a recirculation mode for reducing the content of ozone leads.
