Description

Die vorliegende Erfindung betrifft einen Staubsaugerbeutel zur mehrfachen Verwendung, mit einem Filtermaterial, an dem eine Einströmöffnung und eine verschließbare Entleerungsöffnung vorgesehen sind, wobei an dem Filtermaterial ein Halteelement zur Fixierung des Staubsaugerbeutels an einem Staubsauger vorgesehen ist.The present invention relates to a vacuum cleaner bag for multiple use, with a filter material to which an inflow opening and a closable emptying opening are provided, wherein on the filter material, a holding element for fixing the vacuum cleaner bag is provided on a vacuum cleaner.

Es gibt beutellose Staubsauger, die nach dem Zyklonprinzip arbeiten und bei denen der gröbere Staub in einer zu reinigenden Kammer gesammelt wird. Problematisch ist allerdings feinerer Staub, der sich nicht abscheiden lässt und dann die Filter eines solchen beutellosen Staubsaugers nach und nach verstopft. Dadurch sinkt die Reinigungsleistung oder es müssen in regelmäßigen Intervallen die Filter des Staubsaugers gewechselt werden.There are bagless vacuum cleaners, which operate on the cyclone principle and in which the coarser dust is collected in a chamber to be cleaned. The problem is, however, finer dust that can not be separated and then clogged the filter of such a bagless vacuum cleaner gradually. This reduces the cleaning performance or it must be changed at regular intervals, the filter of the vacuum cleaner.

Ferner gibt es wiederverwendbare Staubsaugerbeutel, die meist aus einem gewebten Stoff bestehen, die geleert und gereinigt werden können und dann nur geringfügig an Saugleistung verlieren. Allerdings ist die Filterwirkung des Filtermaterials gegenüber feineren Partikeln von kleiner 10 µm nahezu gleich Null, so dass diese Partikel nicht gefiltert werden, aber der Staubsaugerbeutel auch durch diese feinen Partikel nicht verstopfen kann.Furthermore, there are reusable vacuum cleaner bags, which usually consist of a woven fabric that can be emptied and cleaned and then lose only a slight amount of suction. However, the filter effect of the filter material compared to finer particles of less than 10 microns is almost zero, so that these particles are not filtered, but the vacuum cleaner bag can not clog even by these fine particles.

Die DE 20 2007 000 103 U1 offenbart einen Staubbehälter für Staubsauger mit einem an einem Ende verschließbaren Beutel, welcher an seinem der verschließbaren Öffnung abgewandten Seite eine Frontplatte aufweist. Als Verbindungselement zwischen Frontplatte und Beutel ist mindestens ein manuell lösbares Klemmelement vorgesehen. Die verschließbare Öffnung ist beispielsweise als Reißverschluss ausgebildet.The DE 20 2007 000 103 U1 discloses a dust container for vacuum cleaners with a bag which can be closed at one end and which has a front plate at its side facing away from the closable opening. As a connecting element between the front panel and bag at least one manually releasable clamping element is provided. The closable opening is designed for example as a zipper.

Die DE 9 316 502 U1 offenbart einen Staubsaugerbeutel mit einer Ansaugöffnung, der aus luftdurchlässigem und zugleich mikrostaubfilternden Material besteht. Dabei weist eine Beutelseite einen Klettverschluss auf, welcher eine Entleerungsöffnung freigibt. Dabei kann das mikrostaubfilternde und luftdurchlässige Material beispielsweise als beschichtetes Baumwoll-Polyester-Gemisch ausgebildet sein.The DE 9 316 502 U1 discloses a vacuum cleaner bag with a suction opening, which consists of air-permeable and at the same time micro-dust filtering material. In this case, a bag side has a hook-and-loop fastener, which releases a discharge opening. In this case, the micro-dust-filtering and air-permeable material may be formed, for example, as a coated cotton-polyester mixture.

Es ist daher Aufgabe der vorliegenden Erfindung einen Staubsaugerbeutel zur mehrfachen Verwendung zu schaffen, der auch kleine Staubpartikel filtern kann und dessen Saugleistung bei der mehrfachen Verwendung kaum nachlässt.It is therefore an object of the present invention to provide a vacuum cleaner bag for multiple use, which can also filter small dust particles and whose suction power hardly decreases in multiple use.

Diese Aufgabe wird mit einem Staubsaugerbeutel mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with a vacuum cleaner bag with the features of claim 1.

Der Staubsaugerbeutel weist ein Filtermaterial auf, das an der Innenseite des Staubsaugerbeutels eine Membranfilterlage zur Oberflächenfiltration aufweist, die an mindestens einer äußeren Materiallage festgelegt ist. Dadurch wird der gefilterte Staub an der Membranfilterlage abgeschieden und kann dann in vorbestimmten Intervallen entfernt werden. Die Membranfilterlage behält Ihre Filterwirkung, weil der abgeschiedene Staub sich nicht in dem Filtermaterial festsetzt sondern durch Oberflächenfiltration abgeschieden wird. Anders als bei Tiefenfiltermedien, bei denen der Staub im gesamten Filtermedium abgeschieden wird und daher eine Wiederverwendung nicht sinnvoll ist, kann bei der Oberflächenfiltration der abgeschiedene Staub entfernt werden, wobei die Membranfilterlage ihre Filterleistung auch über einen längeren Zeitraum beibehält.The vacuum cleaner bag comprises a filter material having on the inside of the vacuum cleaner bag a membrane filter layer for surface filtration, which is fixed to at least one outer material layer. Thereby, the filtered dust is deposited on the membrane filter sheet and can then be removed at predetermined intervals. The membrane filter layer retains its filtering effect because the separated dust does not settle in the filter material but is separated by surface filtration. Unlike in depth filter media, where the dust is deposited throughout the filter medium and therefore reuse is not useful, the deposited dust can be removed during surface filtration, with the membrane filter layer retaining its filtering performance over a longer period of time.

Gemäß einer bevorzugten Ausführungsform weist die Membranfilterlage eine glatte Oberfläche mit Poren auf, die kleiner als 10 µm, vorzugsweise kleiner als 2 µm sind. Dadurch wird eine vergleichsweise feine Staubabscheidung an der Membranfilterlage ermöglicht, die eine bessere Filterwirkung besitzt als Filterlagen aus Gewebe. Durch die Ausbildung einer glatten Oberfläche, also eine folienartige Fläche, kann der abgeschiedene Staub auch leicht von der Membranfilterlage wieder entfernt werden.According to a preferred embodiment, the membrane filter layer has a smooth surface with pores which are smaller than 10 μm, preferably smaller than 2 μm. As a result, a comparatively fine dust separation on the membrane filter layer is made possible, which has a better filtering effect than filter layers made of tissue. By forming a smooth surface, ie a film-like surface, the separated dust can also be easily removed from the membrane filter layer again.

Die Membranfilterlage ist vorzugsweise aus einer Polymermembran mit einer Schichtdicke von kleiner 500 µm gebildet. Als Materialien für die Membranfilterlage eignet sich insbesondere Teflon (PTFE = Polytetrafluorethylen), da sich dort Staub nur an der Oberfläche abscheidet und aufgrund der hohen Glattheit und extrem niedrigen Oberflächenenergie Staub kaum anhaftet. Durch den Einsatz von einer PTFE-Membranfilterlage werden hohe Filterleistungen erreicht, deren Abscheidungsleistung im Bereich der Hepa-Klassifikation gemäß DIN 1822 von H10 bis H 14 liegt.The membrane filter layer is preferably formed from a polymer membrane with a layer thickness of less than 500 microns. Teflon (PTFE = polytetrafluoroethylene) is particularly suitable as materials for the membrane filter layer, since dust only deposits on the surface there and hardly adheres to dust due to the high smoothness and extremely low surface energy. The use of a PTFE membrane filter layer achieves high filter performances, their deposition performance within the range of the Hepa classification according to DIN 1822 from H10 to H14.

Neben Membranfilterlagen aus PTFE können auch andere Membranfilterlagen, beispielsweise aus Celluloseacetat, Cellulose-Nitrat-Ester, regenerierte Cellulose, Polyethersulfon, Polyamid, Polycarbonat oder andere fluorhaltige Polymermembrane eingesetzt werden. Daneben existiert die Möglichkeit, als Membranfilterlage auch anorganische, keramische Materialien wie Aluminiumoxid, Magnesiumoxid und andere Materialien einzusetzen, die bei geringer Schichtdicke von weniger als 500 µm biegsam sind und so ebenfalls als Membranfilterlage eingesetzt werden können.In addition to membrane filter layers made of PTFE, it is also possible to use other membrane filter layers, for example of cellulose acetate, cellulose nitrate ester, regenerated cellulose, polyethersulfone, polyamide, polycarbonate or other fluorine-containing polymer membranes. In addition, there is the possibility to use as a membrane filter layer and inorganic, ceramic materials such as alumina, magnesium oxide and other materials which are flexible at a low layer thickness of less than 500 microns and can also be used as a membrane filter layer.

Die Trägermateriallage besteht vorzugsweise aus einem Vliesstoff, insbesondere aus Polyester oder Polypropylen. Diese Trägermateriallage weist vorzugsweise eine Zugfestigkeit von größer 10 N gemäß Edana 20.2 - 89 und eine Luftdurchlässigkeit von mehr als 200 1/m2 x sec gemäß DIN EN ISO 9237/95 auf. Die Trägermateriallage kann dabei mit der Membranfilterlage verbunden sein, insbesondere durch direktes Aufbringen der Membran im Herstellungsverfahren auf die Trägermateriallage, oder nachträglich über Heißlaminierung, Heißprägen, Heißkalandrierung oder Verkleben. Die Trägermateriallage kann ferner aus einem Spunbond gebildet sein, das ein Flächengewicht von mehr als 20 g/m2 aufweist.The carrier material layer preferably consists of a nonwoven, in particular of polyester or polypropylene. This carrier material layer preferably has a tensile strength of greater than 10 N in accordance with Edana 20.2-89 and an air permeability of more than 200 l / m 2 / sec in accordance with DIN EN ISO 9237/95. The carrier material layer can be connected to the membrane filter layer, in particular by direct application of the membrane in the manufacturing process to the carrier material layer, or subsequently via hot lamination, hot stamping, hot calendering or gluing. The carrier material layer may further be formed of a spunbond having a basis weight of more than 20 g / m 2 .

Gemäß einer weiteren Ausgestaltung der Erfindung ist an der Innenseite der Membranfilterlage eine Innenlage zum Schutz der Membranfilterlage und zur Staubspeicherung vorgesehen. Diese Innenlage kann beispielsweise aus einem voluminösen Krempelvlies, Schaumgummi oder wassergestrahltem Spunbond mit mehr als 20 g/m2 Flächengewicht und einer Dicke von 0,2 mm bis 7 mm bestehen. Bei einer solchen Ausgestaltung besitzt der mehrfach verwendbare Staubsaugerbeutel ein Verbundfiltermedium mit einer Trägermateriallage, einer Membranfilterlage und einer Innenlage.According to a further embodiment of the invention, an inner layer for protecting the membrane filter layer and for dust storage is provided on the inside of the membrane filter layer. This inner layer can for example consist of a voluminous carded web, foam rubber or water-blasted spunbond with more than 20 g / m 2 basis weight and a thickness of 0.2 mm to 7 mm. In such an embodiment, the reusable vacuum cleaner bag has a composite filter medium with a carrier material layer, a membrane filter layer and an inner layer.

Gemäß einer weiteren Ausgestaltung sind die Einströmöffnung und die verschließbare Entleerungsöffnung voneinander getrennt angeordnet. Dabei kann die Entleerungsöffnung über einen Verschluss im Gebrauchszustand verschlossen sein, wobei als Verschluss ein Klettverschluss, Reißverschluss, Schieber, ein Faltverschluss, ein Zipperverschluss oder eine Kombination mehrerer Verschlussmechanismen zum Einsatz kommen können. Insbesondere kann die Filtermateriallage auch weggeklappt werden und umlaufend über einen Klettverschluss oder einen anderen Verschluss im Gebrauchszustand abgedichtet werden. Dadurch lässt sich der im Staubsaugerbeutel enthaltene Staub auf einfache Weise entleeren.According to a further embodiment, the inflow opening and the closable emptying opening are arranged separately from one another. In this case, the discharge opening can be closed by a closure in use, wherein As a closure a Velcro, zipper, slider, a folding closure, a zipper closure or a combination of several locking mechanisms can be used. In particular, the filter material layer can also be folded away and sealed circumferentially via a hook and loop fastener or another closure in use. As a result, the dust contained in the vacuum cleaner bag can be emptied in a simple manner.

Gemäß einem weiteren Aspekt der Erfindung ist die Einströmöffnung innerhalb eines Verschlusselementes angeordnet, das die Entleerungsöffnung verschließt. Vorzugsweise ist um die Einströmöffnung eine Halteplatte vorgesehen, die zur Freigabe der Entleerungsöffnung abnehmbar oder verschwenkbar ist. Dadurch kann auf einfache Weise die Halteplatte gleichzeitig als Verschlusselement genutzt werden.According to a further aspect of the invention, the inflow opening is arranged within a closure element which closes the emptying opening. Preferably, a holding plate is provided around the inflow opening, which can be removed or pivoted to release the discharge opening. As a result, the retaining plate can be used simultaneously as a closure element in a simple manner.

Gemäß einer bevorzugten Ausgestaltung der Erfindung ist der Staubsaugerbeutel waschbar, so dass nach einer Reinigung in Wasser oder einer Waschlösung sich der angefallene Staub nahezu vollständig entfernen lässt. Dies sorgt auch für ein hohes Maß an Hygiene.According to a preferred embodiment of the invention, the vacuum cleaner bag is washable, so that after cleaning in water or a washing solution, the accumulated dust can be almost completely removed. This also ensures a high level of hygiene.

Der wiederverwendbare Staubsaugerbeutel soll auch bei einem erneuten Gebrauch eine Staubemission gemäß DIN EN 60312 von weniger als 3 mg/m3 aufweisen.The reusable vacuum cleaner bag should also have a dust emission according to DIN EN 60312 of less than 3 mg / m 3 when used again.

Zur Erläuterung des Gegenstandes der Erfindung wird nachfolgend noch auf die Figur 1 hingewiesen.To explain the subject matter of the invention is still on the FIG. 1 pointed.

Ein wiederverwendbarer Staubsaugerbeutel soll im leeren Zustand einen hohen Saugvolumenstrom durchlassen, also keine Verstopfung aufweisen. Während des Einsaugens von Staub sammelt sich dieser an der Filterfläche an, insbesondere an der Membranfilterlage. Dadurch sinkt der Saugvolumenstrom von der ursprünglichen Leistung bei Punkt A von etwa 132 m3 pro Std. auf die Punkte B und C von rund 123 bis 115 m3 pro Std., bis eine Befüllung von 150 gr. bei Punkt D erreicht ist. Bei einer solchen Befüllung ist der Saugvolumenstrom nur noch rund 95 m3 pro Std.A reusable vacuum cleaner bag should pass a high suction volume flow in the empty state, so have no blockage. During the suction of dust, this accumulates on the filter surface, in particular on the membrane filter layer. As a result, the suction volume flow drops from the original power at point A from about 132 m 3 per hour to points B and C of about 123 to 115 m 3 per hour, until a filling of 150 gr. At point D is reached. With such a filling, the suction volume flow is only about 95 m 3 per hour.

Um den Staubsaugerbeutel wieder zu verwenden, wird nun der eingesaugte Staub entleert, so dass nun wieder ein größerer Saugvolumenstrom durch den Staubsaugerbeutel strömt. Dies ist in der Graphik mit dem Punkt A1 angegeben. Nachfolgend wird wiederum Staub (DMT Typ 8 Staub gemäß DIN EN 60312) in den Staubsaugerbeutel eingefüllt, bis dieser entleert wird, so dass die nachfolgenden Punkte nach dem jeweiligen Entleeren A2, A3 und A4 erreicht werden. Wenn nach dem Entleeren des Staubsaugerbeutels der Saugvolumenstrom von A bis A4 nicht nennenswert absinkt, in einen Bereich von weniger als 2 %, vorzugsweise weniger als 1 %, dann ist die Wiederverwendbarkeit des Staubsaugerbeutels gegeben.In order to use the vacuum cleaner bag again, the sucked dust is now emptied, so that now flows again a larger suction flow through the vacuum cleaner bag. This is indicated in the graph with the point A1. Subsequently, dust (DMT type 8 dust in accordance with DIN EN 60312) is again introduced into the vacuum cleaner bag until it is emptied so that the following points are reached after the respective emptying A2, A3 and A4. If, after emptying the vacuum cleaner bag, the suction volume flow does not drop appreciably from A to A4, in a range of less than 2%, preferably less than 1%, then the reusability of the vacuum cleaner bag is given.
