Description

Die Erfindung betrifft einen Filterbeutel mit Duftelement nach den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to a filter bag with fragrance element according to the features of the preamble of claim 1.

Beim Staubsaugen ist grundsätzlich eine Problematik der Geruchsbelästigung gegeben, durch den im Zuge des Saugvorganges in einem Filterbeutel abgeschiedenen Staub. Die nach dem Abscheiden des Staubes die Filterbeutelwände durchsetzende Saugluft ist in der Regel mit als unangenehm empfundenen Gerüchen belastet.When vacuuming a problem of odor is basically given by the in the course of the suction process in a filter bag separated dust. The suction air passing through the filter bag walls after the dust has been deposited is as a rule loaded with unpleasant odors.

Aus der EP 0 860 138 A1 ist es bekannt, auf der Außenseite eines Filterbeutels ein Duftelement anzubringen. Dieses Filterelement ist jedoch noch nicht zufriedenstellend.From EP 0 860 138 A1 it is known to attach a fragrance element to the outside of a filter bag. However, this filter element is still not satisfactory.

Ausgehend von dem vorgenannten Stand der Technik stellt sich der Erfindung die Aufgabe, ein rationell herstellbares und auch wirksames Duftelement anzugeben.Based on the aforementioned prior art, the object of the invention is to provide a rationally producible and also effective fragrance element.

Diese Aufgabe ist beim Gegenstand des Anspruches 1 gelöst. So ist ein auf der Abluftseite eines Filterbeutels, der mit dieThis object is achieved in the subject matter of claim 1. So is one on the exhaust side of a filter bag, with the

Filterbeutelwände durchsetzender Druckluft staubbeladen wird, angeordnetes Duftelement vorgesehen, wobei das Duftelement auf der Außenseite des Filterbeutels angebracht ist und die Abluft streichend über die Filterbeutelaußenseite abgezogen wird. Zufolge dieser erfindungsgemäßen Ausgestaltung wird der als unangenehm empfundene Staubgeruch durch Beduftung überdeckt, wobei durch die vorteilhafte Anordnung des Duftelementes auf der Außenseite des Filterbeutels zunächst eine Filterung der die Filterbeutelwände durchsetzenden Druckluft erfolgt. Hierbei ist in Saugrichtung hinter dem Filterbeutel ein Gebläsemotor angeordnet, welcher den staubbeladenen Saugluftstrom durch den Filterbeutel saugt. Die aus dem Filterbeutel tretende Abluft streicht über die Filterbeutelaußenseite und nimmt hierbei Duftstoffe aus einem Parfümöl oder dergleichen auf. Das Duftelement ist demnach erfindungsgemäß an einer Stelle im Saugluftkanal angeordnet, welche in Strömungsrichtung hinter den geruchsbelasteten Bereichen, wie dem Sammelraum in dem Filterbeutel, angeordnet. So kann bspw. vorgesehen sein, dass das Duftelement auf der Außenseite der Filterbeutelwandung angebracht ist. Alternativ hierzu wird weiter vorgeschlagen, dass das Duftelement auf einer Halteplatte des Filterbeutels angebracht ist und die Abluft streichend über die Halteplatte abgezogen wird. Hierbei wird der Filterbeutel durch eine Öffnung in der Halteplatte von der, die Filterbeutelwände durchsetzenden Druckluft staubbeladen. Der Filterbeutel sitzt hierbei bevorzugt in einer, eine Kapsel ausbildenden, den Filterbeutel umschließenden Filterkammeraufnahme ein, wobei die Kammerinnenwandung zu den Filterbeutelwänden beabstandet ist. Die aus dem Filterbeutel austretende, geruchsbelastete Abluft wird durch den hierdurch gebildeten Zwischenraum abgezogen und über die Halteplatte geführt, in dessen Bereich eine Kontaktierung des dort angeordneten Duftelementes erfolgt. Als besonders vorteilhaft erweist sich die erfindungsgemäße Lösung in einer Kombination, bei welcher in dem Filterbeutel Adsorbens lose eingebracht ist. Diesbezüglich wird auf die DE 100 30 958 A1 verwiesen. So kann, wie bevorzugt, das Adsorbens in loser Form in dem Staubfilterbeutel vorliegen, wobei weiter bevorzugt Aktivkohlepulver mit einer Korngrößenfraktion zwischen 0,15 und 0,25 oder ein Adsorbens aus Aktivkohlefasern mit einem Faserdurchmesser von 0,01 bis 0,1 mm und einer Faserlänge bis 10 bis 100 mm vorgesehen ist. Darüber hinaus kann das Adsorbens in einer eigenen, luftdurchlässigen Umhüllung innerhalb des Filterbeutels enthalten sein, welche luftdurchlässige Umhüllung bspw. ein Vliesstoff ist. Die Art und Menge der als Adsorbens dienenden Aktivkohle und die Art und Menge der Duftbestandteile in dem Duftelement sind aufeinander abgestimmt. Hieraus ergibt sich der vorteilhafte Effekt, dass die Aktivkohle während der Stillstandszeit, d. h. bei Nichtbenutzung des Staubsaugers, den unangenehmen Geruch des Staubes in dem Filterbeutel adsorbiert und den anfangs gegebenenfalls zu stark austretenden Duft des Duftelementes reduziert. Mit steigendem Füllgrad in dem Filterbeutel wird die Aktivkohle mit Staub umhüllt und nimmt verstärkt nur noch den Staubgeruch auf. Während des Saugens wird der nicht von der Aktivkohle adsorbierte Geruch des neu aufgesaugten Staubes durch den Duft des Duftelementes angenehm überdeckt. Damit ist gewährleistet, dass anfänglich nicht zu stark beduftet, der Staubgeruch in dem Filterbeutel über die Nutzungsdauer desselben adsorbiert und der Staubgeruch während des Saugens überdeckt wird, was eine gleichmäßig angenehm und dezent beduftete Ausblasluft über die gesamte Nutzungsdauer des Filterbeutels gewährleistet. Darüber hinaus ist die Handhabung dadurch deutlich verbessert, dass das Duftelement ein Kunststoffspritzteil ist mit darin eingelagerten Duftbestandteilen. So wird vorgeschlagen, dass das Duftelement bevorzugt aus Polyethylen oder Ethylen-Vinyl-Acetat besteht, wobei im Spritzvorgang etwa 2 bis 20 % Parfümöl mit eingebracht sind. Als weiter handhabungstechnisch vorteilhaft erweist sich ein Gesamtgewicht, welches zwischen 2 und 8 g liegt, wobei die Oberfläche, insbesondere die wirksame, von der Abluft zu überstreichende Oberfläche des Duftelementes etwa 10 bis 100 cm2 beträgt. Die Verteilung der Duftbestandteile, insbesondere des Parfüms in dem Duftelement ist homogen. Darüber hinaus ist das Austreten des Duftöles aus dem Duftelement ausschließlich durch Diffusion möglich. Des Weiteren ist das eingebrachte Parfümöl bevorzugt lösemittelarm zusammengesetzt und darüber hinaus thermisch so stabil, dass eine kurzzeitige Erhitzung auf 150 bis 250°C möglich ist. Das Duftelement kann an dem Filterbeutel, bspw. außenseitig an der Filterbeutelwand oder auf der Halteplatte nicht zerstörungsfrei entfernbar angebracht sein, so bspw. durch Verklebung. Ein solches Duftelement beinhaltet eine Duftölmenge, welche an die übliche Nutzungsdauer eines Filterbeutels angepasst ist. Hierbei erweist sich diese feste Anordnung als vorteilhaft, da bei einem anstehenden Filterbeutelwechsel sowohl das in diesem angeordnete Adsorbens als auch das angebrachte Duftelement mit entsorgt werden und bei einem Einsetzen eines neuen Filterbeutels sowohl die Elemente zur Beduftung als auch zur Geruchsadsorbtion erneuert werden. Alternativ kann jedoch auch vorgesehen sein, dass das Duftelement auf der Halteplatte schiebe- oder clipsgehaltert ist. So können Duftelemente, bevorzugt in Form eines Kunststoffspritzteiles vorliegen, welche eine vorbestimmte Nutzungsdauer, welche die übliche Nutzungsdauer eines Filterbeutels überschreitet, aufweisen. Solche schiebe- oder clipsgehalterten Duftelemente werden in vorbestimmten Intervallen ausgetauscht.Dust element is arranged dust filter bags passing through the filter bag walls, compressed air is arranged, wherein the fragrance element is mounted on the outside of the filter bag and the exhaust air is removed stripping over the filter bag outside. According to this embodiment of the present invention, the unpleasant odor odor is masked by scenting, wherein the advantageous arrangement of the scent element on the outside of the filter bag initially filtering the compressed air passing through the filter bag walls. Here, a blower motor is arranged in the suction direction behind the filter bag, which sucks the dust-laden suction air flow through the filter bag. The exhaust air passing out of the filter bag passes over the outside of the filter bag and absorbs fragrances from a perfume oil or the like. The scent element is therefore arranged according to the invention at a location in the suction air duct, which is arranged in the flow direction behind the odorous areas, such as the collecting space in the filter bag. For example, it may be provided that the fragrance element is mounted on the outside of the filter bag wall. Alternatively, it is further proposed that the fragrance element is mounted on a support plate of the filter bag and the exhaust air is drawn over the retaining plate. Here, the filter bag through an opening in the holding plate of the, Dust loading through filter bag walls. The filter bag is preferably located in a, a capsule forming, the filter bag enclosing a filter chamber receptacle, wherein the chamber inner wall is spaced from the filter bag walls. The odor-laden exhaust air emerging from the filter bag is drawn off through the intermediate space formed thereby and passed over the holding plate, in the region of which a contacting of the scent element arranged there takes place. The solution according to the invention proves to be particularly advantageous in a combination in which adsorbent is introduced loosely in the filter bag. In this regard, reference is made to DE 100 30 958 A1. Thus, as preferred, the adsorbent may be present in loose form in the dust filter bag, more preferably activated carbon powder having a particle size fraction between 0.15 and 0.25 or an adsorbent of activated carbon fibers having a fiber diameter of 0.01 to 0.1 mm and a Fiber length is provided to 10 to 100 mm. In addition, the adsorbent can be contained in its own, air-permeable envelope within the filter bag, which air-permeable envelope, for example, is a nonwoven fabric. The type and amount of activated carbon serving as adsorbent and the type and amount of the fragrance components in the fragrance element are coordinated. This results in the advantageous effect that the activated carbon during the downtime, ie when not using the vacuum cleaner adsorbs the unpleasant odor of the dust in the filter bag and reduces the initially possibly too much exiting fragrance of the fragrance element. As the degree of filling in the filter bag increases, the activated carbon is coated with dust and only absorbs the dust odor. During sucking, the odor of the newly absorbed dust, which is not adsorbed by the activated carbon, is pleasantly covered by the fragrance of the fragrance element. In order to ensures that initially scented too strong, the dust odor in the filter bag adsorbed over its useful life and the dust odor is masked during suction, which ensures a uniformly pleasant and discreet scented exhaust air over the entire useful life of the filter bag. In addition, the handling is significantly improved by the fact that the fragrance element is a plastic injection molded part with embedded therein fragrance ingredients. Thus, it is proposed that the fragrance element preferably consists of polyethylene or ethylene-vinyl acetate, wherein in the injection process about 2 to 20% perfume oil are introduced. As further handling technology advantageous proves to be a total weight, which is between 2 and 8 g, wherein the surface, in particular the effective, to be swept by the exhaust surface of the fragrance element is about 10 to 100 cm 2 . The distribution of the fragrance components, in particular the perfume in the fragrance element is homogeneous. In addition, the escape of the fragrance oil from the fragrance element is possible only by diffusion. Furthermore, the perfume oil introduced is preferably composed of low-solvent and moreover thermally stable so that a brief heating to 150 to 250 ° C is possible. The fragrance element may be attached to the filter bag, for example. On the outside of the filter bag wall or on the plate not destructively removably mounted, so for example. By gluing. Such a fragrance element includes a quantity of fragrance oil which is adapted to the usual service life of a filter bag. In this case, this fixed arrangement proves to be advantageous because in a pending filter bag change both disposed in this adsorbent and the attached fragrance element are disposed of and renewed when inserting a new filter bag, both the elements for scenting and for odor adsorption. Alternatively, however, it can also be provided that the fragrance element is sliding or clip-retained on the retaining plate. Thus fragrance elements, preferably in the form of a plastic injection molded part, which have a predetermined service life, which the usual service life of a filter bag exceeds have. Such sliding or clip-retained fragrance elements are exchanged at predetermined intervals.

Dargestellt und beschrieben ist zunächst mit Bezug zu Fig.1 ein Grundgerät 1 eines Staubsaugers mit einem Staubsaugergehäuse 2 und einer hieran klappbeweglich gehalterten Filterkammer 3 zur Aufnahme eines Filterbeutels 4.1 and 2, a base unit 1 of a vacuum cleaner with a vacuum cleaner housing 2 and a filter chamber 3 supported thereon in a movable manner for receiving a filter bag 4 are shown and described.

Der in dem Grundgehäuse 2 angeordnete, schematisch dargestellte Gebläsemotor 5 saugt über einen in dem Grundgerät 1 angeordneten Saugkanal 6 die staubbeladene Luft an. Dieser Saugkanal 6 ist angeschlossen an eine an einer Halteplatte 9 des Filterbeutels 4 ausgebildeten Füllöffnung 8.The blower motor 5, which is arranged in the base housing 2 and is shown schematically, sucks in the dust-laden air via a suction channel 6 arranged in the base unit 1. This suction channel 6 is connected to a filling opening 8 formed on a holding plate 9 of the filter bag 4.

Der Filterbeutel 4 wird in üblicher Weise durch den eintretenden Luftstrom (Pfeil a) staubbeladen, wonach der Luftstrom, die Filterbeutelwände 10 durchsetzend, zwischen Filterbeutelwand 10 und Kammerinnenwandung 11 unter Umlenkung in eine etwa entgegengesetzte Richtung zur Eintrittsrichtung geführt wird (siehe Pfeil b). Diese staubbefreite und von dem Gebläsemotor 5 angesaugte Luft wird sowohl über die Filterbeutelwände 10 als auch über die Halteplatte 9 streichend abgezogen, was dazu genutzt wird, dass diese Abluft (Pfeil b) über ein auf der Halteplatte 9 angeordnetes Duftelement 12 streicht und hierbei in dem Duftelement 12 eingelagerte Duftbestandteile mitreißt.The filter bag 4 is dust-laden in the usual way by the incoming air flow (arrow a), after which the air flow, the filter bag walls 10 passing through between filter bag wall 10 and chamber inner wall 11 is guided under deflection in an approximately opposite direction to the direction of entry (see arrow b). This dust-free and sucked by the fan motor 5 air is subtracted both on the filter bag walls 10 and on the support plate 9, which is used to that this exhaust air (arrow b) sweeps over a arranged on the support plate 9 fragrance element 12 and in this case Scented element entrains 12 embedded fragrance ingredients.

Das Duftelement 10 ist als Kunststoffspritzteil hergestellt mit darin eingelagerten Duftbestandteilen, wobei bezüglich des Kunststoffmaterials bevorzugt Polyethylen oder Ethylen-Vinyl-Acetat Verwendung findet. Der Duftbestand-Anteil in dem Duftelement 12 beträgt ca. 2 bis 20 %, wobei weiter als Duftbestandteil bevorzugt Parfümöl eingebracht ist, dies bei homogener Verteilung innerhalb des Duftelementes 12. Der Austritt des Duftöles bzw. der Duftbestandteile erfolgt ausschließlich durch Diffusion.The fragrance element 10 is produced as a plastic injection-molded part with fragrance constituents incorporated therein, polyethylene or ethylene-vinyl acetate preferably being used with regard to the plastic material. The fragrance content in the fragrance element 12 is about 2 to 20%, wherein perfume oil is preferably further introduced as the fragrance component, this with a homogeneous distribution within the fragrance element 12. The exit of the fragrance oil or the fragrance ingredients is exclusively by diffusion.

In dem Filterbeutel 4 ist des Weiteren Adsorbens 13 in Form von Aktivkohlepulver oder Aktivkohlefasern eingebracht, wobei die Art und Menge der Aktivkohle und die Art und Menge der in dem Duftelement 12 eingelagerten Duftbestandteilen aufeinander abgestimmt sind. Die Aktivkohle adsorbiert während der Stillstandszeit des Staubsaugers den unangenehmen Geruch des in dem Filterbeutel 4 abgeschiedenen Staubes und den bei neu eingesetztem Filterbeutel gegebenenfalls anfangs zu stark austretenden Duft des Duftelementes 12. Mit steigendem Füllgrad in dem Filterbeutel 4 wird die Kohle umhüllt mit Staub und nimmt verstärkt nur noch den Staubgeruch auf. Während des Saugens wird der nicht von der Aktivkohle adsorbierte Geruch des neu aufgesaugten Staubes durch den Duft des Duftelementes 12 angenehm überdeckt, womit gewährleistet ist, dass anfänglich nicht zu stark beduftet, der Staubgeruch in dem Filterbeutel 4 über die Nutzungsdauer adsorbiert und der Staubgeruch während des Saugens überdeckt wird. Es ist somit eine gleichmäßig angenehm und dezent beduftete Ausblasluft (Pfeil b) über die gesamte Nutzungsdauer des Filterbeutels 4 gewährleistet.In addition, adsorbent 13 in the form of activated carbon powder or activated carbon fibers is introduced into filter bag 4, with the type and amount of activated carbon and the type and amount of fragrance components stored in fragrance element 12 being matched to one another. The activated carbon adsorbs the unpleasant odor during the downtime of the vacuum cleaner in the filter bag 4 separated dust and the newly inserted in the filter bag, if necessary, initially too strong exiting fragrance of the fragrance element 12. With increasing degree of filling in the filter bag 4, the coal is coated with dust and takes up only the dust odor. During the sucking, the odor of the newly sucked-up dust, which is not adsorbed by the activated carbon, is pleasantly covered by the fragrance of the fragrance element 12, thus ensuring that the scent of the fragrance in the filter bag 4 is not adsorbed over the period of use and the odor of the dust during the drying process Sucking is covered. It is thus ensured a uniformly pleasant and subtly scented exhaust air (arrow b) over the entire useful life of the filter bag 4.

Wie in den Darstellungen gemäß den Fig. 2 bis 4 zu erkennen, kann das Duftelement 12 außenseitig, d. h. auf der, dem Filterraum abgewandten Oberfläche der Halteplatte 9 mit dieser verklebt oder je nach Materialwahl der Halteplatte 9 auch verschweißt sein, womit ein stetiger Wechsel von Adsorbens 13 und Duftelement 12 im Wechselzyklus des Filterbeutels 4 gewährleistet ist.As can be seen in the illustrations according to FIGS. 2 to 4, the scent element 12 can be on the outside, ie. H. glued to the filter chamber surface facing away from the holding plate 9 with this or welded depending on the choice of material of the holding plate 9, whereby a steady change of adsorbent 13 and fragrance element 12 is ensured in the cycle of change of the filter bag 4.
