Abstract

1. External filter cassette, which accommodates a paper filter bag, for hand suction cleaners, characterized in that the filter cassette (3) consists of a housing (5) made of tufted material which is permeable to air without additional support elements.

Description

Die Erfindung betrifft eine Filterkassette für Handstaubsauger, welche einen Papierfilterbeutel aufnimmt.The invention relates to a filter cassette for hand vacuum cleaners, which receives a paper filter bag.

Filterkassetten sind entweder in Form von stabilen luftundurchlässigen Gehäusen auf den Markt bekannt oder als mit Stoff bespannte Gitterkörbe.Filter cartridges are either known in the form of stable, air-impermeable housings or as mesh baskets covered with fabric.

Beiden haften von ihrem Aufbau abhängig unterschiedliche Nachteile an.Depending on their structure, both have different disadvantages.

Die festen Gehäuse bestehen aus Kunststoff und sind somit luftundurchlässig. Da jedoch die in den, im Gehäuse angeordneten Papierfilterbeutel einströmende Luft auch wieder abgeführt werden muß, muß das feste Gehäuse mit Öffnungen versehen sein. Diese werden dann zusätzlich mit einem filternden Medium abgedeckt, um den sogenannten Feinstaub aufzuhalten, der vom Papierfilterbeutel evtl. nicht erfaßt wird. Solche Gehäuse sind aus dem DE-U-6 907 559 bekannt geworden.The fixed housings are made of plastic and are therefore impermeable to air. However, since the air flowing into the paper filter bag arranged in the housing must also be removed again, the fixed housing must be provided with openings. These are then additionally covered with a filtering medium in order to stop the so-called fine dust, which may not be captured by the paper filter bag. Such housings are known from DE-U-6 907 559.

Dies verteuert u. a. die Herstellung solcher Filterkassetten und man kann nur einen geringen Teil des festen Gehäuses als Abluftfläche ausnutzen, da das Gehäuse sonst instabil wird.This makes u more expensive. a. the production of such filter cartridges and you can only use a small part of the fixed housing as an exhaust air surface, otherwise the housing will become unstable.

Bei den mit Stoff bespannten Gitterkörben ist zwar nahezu die gesamte Fläche als Abluftöffnung zu benutzen, jedoch entstehen hier andere Nachteile.With the mesh baskets covered with fabric, almost the entire surface can be used as an exhaust air opening, but there are other disadvantages here.

Beim Einblasen der Luft in den Papierfilterbeutel bläht sich dieser auf und drückt den Gitterkorb gegen den Stoff. Da beim Arbeiten mit dem Staubsauger Bewegungen entstehen, können die Stege des Gitterkorbes mit der Zeit den Stoff durchscheuern. Außerdem malen sich die Stege mit der Zeit u. a. auch durch Staubansammlungen am Stoff ab, was zu unschönem Aussehen führt. Solche Filterkassette sind aus der DE-A-1 428 431 und dem DE-U-7 626 772 bekannt geworden.When the air is blown into the paper filter bag, it inflates and presses the mesh basket against the fabric. Since movements occur when working with the vacuum cleaner, the bars of the mesh basket can wear through the fabric over time. In addition, the bridges paint over time. a. also through dust accumulation on the fabric, which leads to an unsightly appearance. Such filter cassettes are known from DE-A-1 428 431 and DE-U-7 626 772.

Aufgabe der Erfindung ist es nun, eine Filterkassette zu erstellen, welche ohne zusätzliche Stützelemente auskommt und trotzdem wie eine stoffbezogene Filterkassette die gesamte Oberfläche als Abluftfilterfläche zu Verfügung hat.The object of the invention is now to create a filter cassette which does not require additional support elements and yet, like a fabric-related filter cassette, has the entire surface available as an exhaust air filter surface.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruchs 1 gelöst. Zusätzlich je nach Einsatzbereich und Anwendungsfall kann die Dicke der einzelnen Seiten der Filterkassetten variiert werden.According to the invention the object is achieved by the features of claim 1. In addition, depending on the area of application and application, the thickness of the individual sides of the filter cassettes can be varied.

Nachstehend ist ein Ausführungsbeispiel der Erfindung gezeichnet und beschrieben.An exemplary embodiment of the invention is drawn and described below.

Es zeigt :

  • Figur 1 Die Prinzipskizze eines Handstaubsaugers mit außenliegender Filterkassette,
  • Figur 2 die Prinzipskizze einer Filterkassette,
  • Figur 3 eine Filterkassette im Teilabschnitt.
It shows :
  • 1 shows the basic sketch of a hand-held vacuum cleaner with an external filter cassette,
  • FIG. 2 shows the basic sketch of a filter cassette,
  • Figure 3 shows a filter cartridge in the section.

Die Figur 1 zeigt einen Handstaubsauger 1, welcher aus einem Motorkopf 2, einer außenliegenden Filterkassette 3 und einem Führungsstiel 4 besteht.FIG. 1 shows a handheld vacuum cleaner 1 which consists of a motor head 2, an external filter cassette 3 and a guide handle 4.

Die Filterkassette 3 nach Figur 2 besteht dabei im Wesentlichen aus einem äußeren Gehäuse 5 und einen Rahmen 6 an dem die Filterkassette 3 mit dem Motorkopf 2 des Staubsaugers 1 nach Figur 1 verbunden wird. Der genaue Aufbau ist der Figur 3 zu entnehmen.The filter cassette 3 according to FIG. 2 essentially consists of an outer housing 5 and a frame 6 on which the filter cassette 3 is connected to the motor head 2 of the vacuum cleaner 1 according to FIG. 1. The exact structure can be seen in FIG. 3.

Der Rahmen 6 hat zwei Funktionen. Er trägt das Gehäuse 5 und einen abnehmbaren Deckel 7. Das Gehäuse 5 ist aus luftdurchlässigem Nadelvliesstoff, der z. B. tiefziehfähig sein kann hergestellt. Derartige Stoffe sind z. B. unter dem Markennamen « Paradur » auf dem Markt bekannt. Da diese Nadelvliesstoffe steif und selbsttragend sind, erübrigt sich ein Stützgehäuse bzw. Stützelemente. Trotzdem ist das Gehäuse auf der gesamten Oberfläche filternd luftdurchlässig.The frame 6 has two functions. He carries the housing 5 and a removable cover 7. The housing 5 is made of air-permeable needle-punched nonwoven fabric, which, for. B. can be thermoformed. Such substances are e.g. B. known under the brand name "Paradur" on the market. Since these needle-punched nonwovens are rigid and self-supporting, there is no need for a support housing or support elements. Nevertheless, the housing is air-permeable, filtering on the entire surface.

Desweiteren trägt der Rahmen 6 ein Deckel 7, der abnehmbar vom Rahmen 6 angeordnet ist.Furthermore, the frame 6 carries a cover 7, which is arranged detachably from the frame 6.

Dieser Deckel 7 hat eine Öffnung 8, welche die Verbindung mit dem Staubgebläse im Staubsauger (beides nicht dargestellt) herstellt und damit verbunden einen Stutzen 9, der die auswechselbare Papierfiltertüte 10 trägt.This lid 7 has an opening 8, which establishes the connection with the dust blower in the vacuum cleaner (neither of which is shown) and is connected to a nozzle 9 which carries the exchangeable paper filter bag 10.

Eine derartige Filterkassette 3 kann durch den Einsatz von Nadelvliestoff einfach und billig hergestellt werden. Sie ist sogar ohne Deckel 7 und Papierfiltertüte 10 waschbar. Der Einsatz von Nadelvliesstoff als Gehäuse ohne zusätzliche Stützelemente ist dabei selbstverständlich nicht nur auf die dargestellte Form beschränkt.Such a filter cassette 3 can be produced simply and cheaply by using needle-punched nonwoven fabric. It is even washable without a lid 7 and paper filter bag 10. The use of needle-punched nonwoven fabric as a housing without additional support elements is of course not limited to the shape shown.
