Vorrichtung zur Zuführung von GeruchsstoffenDevice for supplying odorous substances

Die Erfindung betrifft eine Vorrichtung zur Zuführung von Geruchsstoffen, insbesondere für ein Kraftfahrzeug, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for supplying odorous substances, in particular for a motor vehicle, according to the preamble of claim 1.

Aus der FR 28 15 294 ist eine Klima- oder Heizungsanlage für ein Kraftfahrzeug bekannt mit einer Vorrichtung zur Zuführung von Geruchsstoffen, wel- ehe direkt in die Klima- oder Heizungsanlage integriert ist. Diese integrierte Ausgestaltung bietet zwar gewisse Vorteile, jedoch lässt sie in Hinblick auf die Benutzung noch Wünsche offen.From FR 28 15 294 an air conditioning or heating system for a motor vehicle is known with a device for supplying odorous substances, which is integrated directly into the air conditioning or heating system. Although this integrated configuration offers certain advantages, it still leaves something to be desired in terms of use.

Aus der DE 100 33 917 A1 ist eine Düse für die Abgabe von Wirkstoffen be- kannt, wobei ein Düsenkörper, welcher einen Anschluss für eine Luftleitung hat, eine langgestreckte Röhre zur Aufnahme einer Wirkstoffkartusche aufweist. Eine derartige Anordnung wird normalerweise in Häusern verwendet, beispielsweise in Läden, ist aber für die Anwendung in Fahrgastzellen von Kraftfahrzeugen nicht geeignet.A nozzle for dispensing active substances is known from DE 100 33 917 A1, a nozzle body which has a connection for an air line having an elongated tube for receiving an active substance cartridge. Such an arrangement is normally used in houses, for example in shops, but is not suitable for use in passenger compartments of motor vehicles.

Es ist Aufgabe der Erfindung, eine verbesserte Vorrichtung für Kraftfahrzeuge zur Verfügung zu stellen.It is an object of the invention to provide an improved device for motor vehicles.

BESTÄTCUNGSKOP.E Diese Aufgabe wird gelöst durch eine Vorrichtung zur Zuführung von Geruchsstoffen mit den Merkmalen des Anspruchs 1. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.BESTÄTCUNGSKOP.E This object is achieved by a device for supplying odorous substances with the features of claim 1. Advantageous refinements are the subject of the dependent claims.

Die Geruchsstoffzuführung in der Raumluft kann beim Menschen verschiedene Reaktionen hervorrufen, die positiv oder negativ auf seine Stimmungslage wirken. Bei den positiven Wirkungen reicht das Spektrum von Entspannung bei niedrigem Erregungslevel über Glück bis zur Stimulation bei hohem Erregungslevel. Die negativen Wirkungen reichen von Apathie bei niedrigem Erregungslevel über Depressionen bis zum Stress bei hohem Level.The odorant supply in the room air can cause various reactions in humans, which have a positive or negative effect on their mood. The positive effects range from relaxation with a low level of arousal to happiness to stimulation with a high level of arousal. The negative effects range from apathy at a low level of arousal to depression to stress at a high level.

Zur Optimierung der Geruchsstoffzufuhr umfaßt die erfindungsgemäße Vorrichtung zur Zuführung von Geruchsstoffen in den Innenraum eine Steuer- einheit, die die Zufuhr von Geruchsstoffen so einstellt, dass ein aktueller Wert einer Geruchsstoffkonzentration im Innenraum im Bereich zwischen einer Wahrnehmungsschwelle und einer Erkennungsschwelle liegt. Zur besonders feinen Dosierung der Geruchsstoffe erfolgt der Stoffübergang vom Geruchsstoff an einen Luftstrom für den Innenraum durch Verdunstung. Da- bei soll mittels der Zuführung von Geruchsstoffen eine behagliche, stressfreie Atmosphäre im Fahrzeug geschaffen werden, ohne negative Begleiterscheinungen. Hierbei erfolgt insbesondere eine optimierte Geruchsstoffzuführung, da es, um den Geruch eines Raumes wahrnehmen zu können, nicht ausreicht, ihn mit einem Geruchsstoff konstanter Konzentration anzu- reichern. So gewöhnen sich bereits nach kurzer Zeit die Geruchszellen des Menschen an den Geruchsstoff, d.h. den Duft, und die Wahrnehmungsschwelle und die Erkennungsschwelle müßten permanent auf ein höheres Niveau gebracht werden.To optimize the supply of odorous substances, the device according to the invention for supplying odorous substances to the interior comprises a control unit which adjusts the supply of odorous substances such that a current value of an odorous substance concentration in the interior lies in the range between a perception threshold and a detection threshold. For particularly fine dosing of the odorants, the mass transfer from the odorant to an air flow for the interior takes place through evaporation. The aim is to create a comfortable, stress-free atmosphere in the vehicle by adding odorants, without negative side effects. Here, in particular, an optimized odorant supply takes place, because in order to be able to perceive the smell of a room, it is not sufficient to enrich it with an odorant of constant concentration. After a short time, the human olfactory cells get used to the odorant, i.e. the fragrance, and the threshold of perception and the threshold of recognition would have to be constantly raised to a higher level.

Bei einer besonders einfachen Ausführungsform der Erfindung umfaßt die Steuereinheit eine Zeitmessschaltung, die die Zufuhr der Geruchsstoffe in den Innenraum abwechselnd für eine vorgegebene erste Zeitspanne aktiviert und anschließend für eine vorgegebene zweite Zeitspanne deaktiviert. Die Zeitspannen für die Aktivierung bzw. Deaktivierung können dabei vorab ab- hängig von den aktuellen Umgebungsbedingungen, beispielsweise Größe (Volumen) des Innenraums, Anordnung der Vorrichtung usw. für jeden Fahrzeugtyp fest vorgegeben werden.In a particularly simple embodiment of the invention, the control unit comprises a time measurement circuit which alternately activates the supply of the odorous substances into the interior for a predetermined first time period and then deactivates them for a predetermined second time period. The time periods for activation or deactivation can depend in advance on the current environmental conditions, for example size (Volume) of the interior, arrangement of the device, etc. for each vehicle type.

Zudem ist es aber bei einer alternativen Ausführungsform möglich, die bei- den Zeitspannen abhängig von aktuell mittels Sensoren ermittelter Umgebungsdaten wie beispielsweise die Temperatur im Innenraum und/oder die Umgebungstemperatur und/oder die Luftfeuchtigkeit im Innenraum und/oder die Umgebungsluftfeuchtigkeit und/oder das Luftvolumen im Innenraum und/oder das zugeführte Luftvolumen und/oder ein Frisch- luft/Umluftverhältnis während des Betriebs ständig an die vorhandenen Umgebungsbedingungen anzupassen. Zur Erleichterung der Auswertung können für einen Vergleich Kennfelder in der Steuereinheit gespeichert sein. Zudem können Schwellwerte für die einzelnen Parameter oder Parametergruppen fest vorgegeben sein, bei denen eine Aktivierung bzw. eine Deakti- vierung der Zufuhr von Geruchsstoffen in den Innenraum erfolgt. Diese Schwellwerte können aber auch in Abhängigkeit von aktuell ermittelten Sensordaten variiert werden. Bei dieser Ausführungsform steuert also die Steuereinheit in Abhängigkeit von vorgegebenen Daten und/oder Sensorsignalen die Zufuhr von Geruchsstoffen an den Innenraum.In addition, however, in an alternative embodiment, it is possible for the two time spans to depend on ambient data currently determined by means of sensors, such as the temperature in the interior and / or the ambient temperature and / or the air humidity in the interior and / or the ambient air humidity and / or the air volume in the interior and / or the supplied air volume and / or a fresh air / recirculation ratio during operation to constantly adapt to the existing ambient conditions. To facilitate the evaluation, characteristic maps can be stored in the control unit for a comparison. In addition, threshold values can be predefined for the individual parameters or parameter groups, at which activation or deactivation of the supply of odorous substances into the interior takes place. However, these threshold values can also be varied depending on the sensor data currently being determined. In this embodiment, the control unit controls the supply of odorous substances to the interior as a function of predefined data and / or sensor signals.

Bei einer besonders vorteilhaften Ausführungsform werden zur Aktivierung bzw. Deaktivierung der Zufuhr von Geruchsstoffen die Sensorsignale eines oder mehrerer Oxidationssensoren zur Messung der Geruchsstoffkonzentration ausgewertet und mit den entsprechenden Schwellwerten verglichen.In a particularly advantageous embodiment, in order to activate or deactivate the supply of odorous substances, the sensor signals of one or more oxidation sensors for measuring the odorous substance concentration are evaluated and compared with the corresponding threshold values.

Bei einer weiteren Ausführungsform ist eine Wahlmöglichkeit zwischen verschiedenen Geruchsstoffen vorgesehen. So kann dem Innenraum beispielsweise während der Aufheizphase ein Geruchsstoff zugeführt werden, welcher ein Wärmegefühl vermittelt, oder während der Abkühlphase ein Ge- ruchsstoff zugeführt werden, welcher ein Kältegefühl vermittelt. Dabei kann die Dosierung so sein, dass die Konzentration des Geruchsstoffes im Fahrzeuginnenraum so groß ist, dass sie zwischen der sogenannten Erkennungsschwelle und der sogenannten Wahrnehmungsschwelle liegt. D.h. der Insasse erkennt nicht, was er riecht, hat aber ein gewisses Wärme- bzw. Fri- schegefühl. Dabei können für das Wärmegefühl beispielsweise "schwere" Geruchsstoffe wie der Geruch nach Laubgehölzen wie Birken, Buchen, Kirsche oder Walderde verwendet werden. Für das Frischegefühl können beispielsweise "leichte" Geruchsstoffe wie Minze, Eukalyptus, Menthol, frisches, mit Tau benetztes Grün verwendet werden.In a further embodiment, a choice between different odorants is provided. For example, an odorant that gives a feeling of warmth can be added to the interior during the heating phase, or an odorant that gives a feeling of cold during the cooling phase. The dosage can be such that the concentration of the odorant in the vehicle interior is so large that it lies between the so-called detection threshold and the so-called perception threshold. This means that the occupant does not recognize what he smells, but has a certain feeling of warmth or freshness. For example, "heavy" Fragrances such as the smell of deciduous trees such as birch, beech, cherry or forest earth are used. For the feeling of freshness, for example, "light" odorants such as mint, eucalyptus, menthol, fresh green, wetted with dew can be used.

Bei einer vorteilhaften Ausführungsform ist die Vorrichtung in die Mitteldüse einer Klima- oder Heizungsanlage integriert, wobei sie zumindest zeitweise unabhängig von derselben sein kann.In an advantageous embodiment, the device is integrated in the center nozzle of an air conditioning or heating system, and it can be independent of it at least at times.

Gemäß einer alternativen Ausführungsform ist die Vorrichtung im Fahrzeughimmel integriert ausgebildet. Dies ermöglicht eine zugfreie Förderung von Umluft aus dem Fahrzeuginnenraum. Dabei kann - sofern ein Filter vorgesehen ist - lediglich eine Filterung erfolgen oder auch eine Filterung unter Beigabe von einem Geruchsstoff. Dabei ist die Vorrichtung vorzugsweise mittig zwischen Fahrer- und Beifahrersitz im Fahrzeughimmel integriert ausgebildet, so dass eine gleichmäßige Verteilung über den gesamten Fahrzeuginnenraum möglich ist.According to an alternative embodiment, the device is integrated in the vehicle headlining. This enables draft-free conveying of circulating air from the vehicle interior. Provided that a filter is provided, only filtering can be carried out or filtering with the addition of an odorant. The device is preferably integrated in the center between the driver and passenger seats in the vehicle headlining, so that a uniform distribution over the entire vehicle interior is possible.

Bei einer anderen Ausführungsform ist die Vorrichtung als separate Einheit ausgebildet, so dass sie einfach als Zusatzausstattung eingebaut werden kann.In another embodiment, the device is designed as a separate unit, so that it can be easily installed as additional equipment.

Vorzugsweise weist die Vorrichtung eine Kartusche oder einen Behälter aufweist, welcher den Geruchsstoff oder die Geruchsstoffe enthält. Dabei ist die Kartusche oder der Behälter vorzugsweise austauschbar und recyclebar ausgeführt.The device preferably has a cartridge or a container which contains the odorous substance or substances. The cartridge or container is preferably designed to be exchangeable and recyclable.

Es ist ebenfalls möglich, eine erfindungsgemäße Vorrichtung partiell in eine Klima- oder Heizungsanlage zu integrieren, wobei eine Aktivierung oder De- aktivierung der Vorrichtung unabhängig vom Betrieb der eigentlichen Temperierung des Fahrzeuginnenraums ist. Die Vorrichtung kann deshalb bei einer vorteilhaften Ausführungsform ein Gebläse und/oder einen eigenen Luftzuführkanal in den Innenraum umfassen, damit eine unabhängige Zufuhr von Geruchsstoffen in den Innenraum möglich ist, wobei die hierzu verwen- dete Luft gegebenenfalls auch zuerst ein Filter durchströmen kann, bevor sie mit dem oder den Geruchsstoffen versetzt wird.It is also possible to partially integrate a device according to the invention into an air conditioning or heating system, with activation or deactivation of the device being independent of the operation of the actual temperature control of the vehicle interior. In an advantageous embodiment, the device can therefore include a blower and / or its own air supply duct into the interior, so that an independent supply of odorous substances into the interior is possible, the used for this purpose If necessary, air can first flow through a filter before it is mixed with the odorant (s).

Im Folgenden wird die Erfindung anhand zweier Ausführungsbeispiele unter Bezugnahme auf die beiliegende Zeichnung im Einzelnen erläutert. Es zeigen:The invention is explained in detail below using two exemplary embodiments and with reference to the accompanying drawing. Show it:

Fig. 1 eine geschnitten und schematisch dargestellte Anordnung gemäß dem ersten Ausführungsbeispiel, undFig. 1 is a sectional and schematically illustrated arrangement according to the first embodiment, and

Fig. 2 eine geschnitten und schematisch dargestellte Anordnung gemäß dem zweiten Ausführungsbeispiel.Fig. 2 is a sectional and schematically illustrated arrangement according to the second embodiment.

Eine erfindungsgemäße Vorrichtung 1 zur Zuführung von Duft- oder Ge- ruchsstoffen ist in einem Kraftfahrzeug im Bereich des Fahrzeughimmels mittig zwischen dem Fahrer- und Beifahrersitz angeordnet. Diese Vorrichtung 1 gemäß dem ersten Ausführungsbeispiel ist vollständig unabhängig von einer sich ebenfalls im Kraftfahrzeug befindlichen Klimaanlage ausgebildet. Die Vorrichtung 1 weist ein Gebläse 2 und einen Filter, vorliegend einen Hybridfilter 3 auf, welcher speziell auf in Fahrzeugkabinen vorkommende Schadstoffe und Rauchpartikel optimiert wurde. Ferner sind, verschlossen mittels einer Verschlussvorrichtung 4, drei Duftkammern 5 vorgesehen. Jede der drei Duftkammern 5 steht in Verbindung mit einer austauschbaren und wiederbefüllbaren Kartusche (nicht dargestellt), in der sich unterschiedliche Geruchsstoffe befinden. Dies Kartuschen geben bei Bedarf den gewünschten Geruchsstoff an eine jeder Kartusche zugeordnete Duftkammer 5 ab. Ferner ist ein Auslass mit einem Austrittsgitter 6 vorgesehen. Im Bereich zwischen Hybridfilter 3 und Austrittsgitter 6 ist ein Sensor 8, insbesondere ein Oxidationssensor, angeordnet, welcher die Konzentration des Geruchs- Stoffes in diesem Bereich ermittelt. Ferner ist eine Steuereinheit (nicht dargestellt) vorgesehen, welche die ermittelte Konzentration des Geruchsstoffes mit einem vorgegebenen Schwellwert vergleicht und entsprechend den Bedarf ermittelt und die Zufuhr des gewünschten Geruchsstoffes steuert. Die Funktion der Vorrichtung 1 ist folgende: Wird die Vorrichtung 1 von einem Insassen mittels einer Betätigungsvorrichtung, beispielsweise einem Tastschalter, eingeschaltet, um die Luft im Fahrzeuginnenraum zu filtern, so saugt das Gebläse 2 Luft aus der Fahrzeuginnenraum mit niedrigen An- Sauggeschwindigkeiten, d.h. mit Ansauggeschwindigkeiten von maximal 0,3 m/s, an. Diese Luft wird anschließend über den Hybridfilter 3 geleitet und strömt über den Auslass durch das Austrittsgitter 6 und wird gefiltert wieder dem Fahrzeuginnenraum zugeführt.A device 1 according to the invention for supplying fragrance or odor substances is arranged in the middle of the vehicle headlining between the driver's and front passenger's seats in a motor vehicle. This device 1 according to the first exemplary embodiment is completely independent of an air conditioning system that is also located in the motor vehicle. The device 1 has a blower 2 and a filter, in the present case a hybrid filter 3, which has been optimized especially for pollutants and smoke particles occurring in vehicle cabins. Furthermore, three fragrance chambers 5 are provided, closed by means of a closure device 4. Each of the three fragrance chambers 5 is connected to an exchangeable and refillable cartridge (not shown), in which different odorous substances are located. If necessary, these cartridges deliver the desired odorant to a fragrance chamber 5 assigned to each cartridge. An outlet with an outlet grille 6 is also provided. A sensor 8, in particular an oxidation sensor, is arranged in the area between the hybrid filter 3 and the outlet grille 6 and determines the concentration of the odorant in this area. Furthermore, a control unit (not shown) is provided, which compares the determined concentration of the odorant with a predetermined threshold value and determines the demand accordingly and controls the supply of the desired odorant. The function of the device 1 is as follows: If the device 1 is switched on by an occupant by means of an actuating device, for example a pushbutton switch, in order to filter the air in the vehicle interior, the blower 2 sucks air out of the vehicle interior with low suction speeds, ie with Suction speeds of up to 0.3 m / s. This air is then passed through the hybrid filter 3 and flows through the outlet through the outlet grille 6 and is filtered and fed back to the vehicle interior.

Wählt der Insasse über die Betätigungsvorrichtung, welche mit der Verschlussvorrichtung 4 der Duftkammern 5 verbunden ist, zusätzlich einen Duft, d.h. einen Duft- oder Geruchsstoff aus, so wird nach dem Hybridfilter 3 der Geruchsstoff dem Luftstrom in Folge von Verdunstung bei Überblasen eines entsprechenden Behälters zugegeben. Dabei wird die Verschlussvor- richtung 4 der Duftkammern 5, in der sich der Geruchsstoff befindet und die vorliegend direkt mit der Betätigungsvorrichtung verbunden ist, geöffnet, so dass der Geruchsstoff direkt in den Bereich zwischen Hybridfilter 3 und Aus- trittsgitter 6 und durch das Austrittsgitter 6 in den Fahrzeuginnenraum gelangen kann. Bei der beschriebenen Ausführungsform wird die Vorrichtung zur Zufuhr von Geruchsstoffen nach einer Fahrzeugbenutzung abgeschaltet und muß bei jeder Inbetriebnahme des Fahrzeugs vom Benutzer erneut eingeschaltet werden.If the occupant additionally selects a fragrance via the actuation device which is connected to the closure device 4 of the fragrance chambers 5, i.e. a fragrance or odorant, then after the hybrid filter 3 the odorant is added to the air flow as a result of evaporation when a corresponding container is blown over. In this case, the closure device 4 of the fragrance chambers 5, in which the fragrance is located and which in the present case is directly connected to the actuating device, is opened, so that the odorant directly into the area between the hybrid filter 3 and the outlet grill 6 and through the outlet grill 6 can get into the vehicle interior. In the embodiment described, the device for supplying odorous substances is switched off after use of the vehicle and must be switched on again by the user each time the vehicle is started up.

Die Verschlussvorrichtung 4 der Duftkammern 5 wird zusätzlich in Abhängig- keit der ermittelten Geruchsstoffkonzentration im Bereich zwischen dem Hybridfilter 3 und dem Austrittsgitter 6 gesteuert, wobei bei Erreichen eines oberen Schwellwertes die Verschlussvorrichtung 4 geschlossen und bei Erreichen eines unteren Schwellwertes bei Aktivierung der Zuführung von Geruchsstoffen die Verschlussvorrichtung 4 geöffnet wird.The closure device 4 of the fragrance chambers 5 is additionally controlled as a function of the determined odorant concentration in the area between the hybrid filter 3 and the outlet grille 6, the closure device 4 being closed when an upper threshold value is reached and when the supply of odorants is activated, the closure device 4 is closed Closure device 4 is opened.

Gemäß einer nicht dargestellten Ausführungsform erfolgt die Abgabe des ausgewählten Geruchsstoffes getaktet, d.h. die Verschlussvorrichtung oder die entsprechende Kartusche wird abwechselnd geöffnet und geschlossen. Dabei erfolgt die Taktung durch die Steuereinheit in Abhängigkeit von der aktuellen Temperatur im Fahrzeuginnenraum und der an der Klimaanlage eingestellten Soll-Temperatur, mit deren Hilfe die Wirkung der Klimaanlage durch geeignete Geruchsstoffe für den Insassen scheinbar beschleunigt wird, d.h. durch die Geruchsstoffe ein Frische- oder Wärmegefühl erzeugt wird.According to an embodiment not shown, the selected odorant is dispensed in a timed manner, ie the closure device or the corresponding cartridge is alternately opened and closed. The timing is carried out by the control unit depending on the current temperature in the vehicle interior and that on the air conditioning system Set target temperature, with the help of which the effect of the air conditioning system is apparently accelerated by suitable odorants for the occupant, that is to say that the odorants create a feeling of freshness or warmth.

Gemäß einem zweiten, in Fig. 2 dargestellten Ausführungsbeispiel wird in einer entsprechenden Vorrichtung 11 nach einem Gebläse 12 und dem Hybridfilter 13 ein Teil des Luftstromes abgezweigt und durch einen Bypass 19 geleitet und einer Duftkammer 15 zugeführt, in dem der gewünschte Duft- stoff gespeichert ist, d.h. mit dem eine oder mehrere Kartuschen mit dem bzw. den Geruchsstoffen verbunden sind. Die beiden Teile des Luftstromes werden anschließend wieder zusammengeführt, wobei der mit dem Duftstoff versehene Teil über eine semipermeable Membran dem Hauptstrom zugeführt wird.According to a second exemplary embodiment shown in FIG. 2, a part of the air flow is branched off in a corresponding device 11 after a blower 12 and the hybrid filter 13 and passed through a bypass 19 and fed to a fragrance chamber 15 in which the desired fragrance is stored , ie with which one or more cartridges are connected to the odorant (s). The two parts of the air stream are then brought together again, the part provided with the fragrance being fed to the main stream via a semipermeable membrane.

Gemäß einer Variante ist die Vorrichtung nicht im Fahrzeughimmel, sondern in die Mitteldüse einer Klima- oder Heizanlage integriert. Um den Stoffübergang vom Geruchsstoff an den Hauptluftstrom gleichmäßig zu gestalten, wird bei der Aktivierung durch die Steuereinheit ein Ventil (bzw. Klappe) am Eingang des Bypasses langsam und ein Ventil (bzw. Klappe) am Ausgang des Bypasses sofort vollständig geöffnet, diese Maßnahme erlaubt es die mit Geruchsstoff gesättigte Luft in der Duftkammer 15 gleichmäßig mit dem Hauptluftstrom zu vermischen, wobei die Zeitdauer und die Funktion über die das Ventil am Eingang geöffnet wird von der Steuereinheit beispielsweise abhängig von der Zeitdauer der Deaktivierung und/oder der Temperatur usw. bestimmt wird.According to a variant, the device is not integrated in the vehicle headlining, but in the central nozzle of an air conditioning or heating system. In order to make the mass transfer from the odorant to the main air flow uniform, a valve (or flap) at the inlet of the bypass is slowly opened when the control unit is activated and a valve (or flap) at the outlet of the bypass is fully opened immediately, this measure is permitted it to mix the air saturated with odorant in the fragrance chamber 15 uniformly with the main air flow, the length of time and the function by which the valve at the inlet is opened being determined by the control unit, for example depending on the length of time of the deactivation and / or the temperature etc. ,
