Description

Die Erfindung bezieht sich auf einen Filterbeutelzwischenträger zwischen einer oberhalb eines Motorgebläses angeordneten Filterkassette und dem Motorgehäuse.The invention relates to an intermediate filter bag carrier between a filter cassette arranged above a motor fan and the motor housing.

Der durch ein Scharnier abschwenkbare Filterbeutelzwischenträger weist Führungsnocken auf, welche in Greifnischen einer Bodenplatte eines Filterbeutels eintauchen.The filter bag intermediate carrier, which can be pivoted off by a hinge, has guide cams which plunge into gripping niches of a base plate of a filter bag.

Bisher werden, wie aus dem Patent DE 19 337 bekannt, beim Schließen des Filterbeutelzwischenträgers zwei Fuhrungsnocken in die Greifnischen der Bodenplatte eines Filterbeutels eingepaßt. So ist gewährleistet, daß der am Zwischendeckel angebrachte Stutzen zentriert in den Filterbeutel eintaucht. Die Führungsnocken allein können aber nicht verhindern, daß Filterbeutel, die nicht gerätespezifisch ausgelegt sind - die also keine Greifnischen aufweisen, durch die die Führungsnocken gleiten können - verwendet werden.So far, as known from patent DE 19 337, two guide cams are fitted into the gripping niches of the bottom plate of a filter bag when the filter bag intermediate carrier is closed. This ensures that the nozzle attached to the intermediate cover is centered in the filter bag. However, the guide cams alone cannot prevent filter bags that are not designed to be device-specific - that is to say have no gripping niches through which the guide cams can slide - be used.

Der Widerstand, der den Führungsnocken durch eine Bodenplatte mit fehlenden Greifnischen entgegengebracht wird, kann durch starken Druck beim Schließen der Filterkassette überwunden werden. Auf diese Weise kann der Staubsauger mit Filtertüten betrieben werden, die falsch angebracht sind, weil sie nicht gerätespezifisch ausgelegt sind.The resistance that the guide cams face due to a base plate with missing gripping niches can be overcome by applying strong pressure when closing the filter cartridge. In this way, the vacuum cleaner can be operated with filter bags that are incorrectly attached because they are not designed for specific devices.

Das hat zur Folge, daß die Filterbeutel nicht ordnungsgemäß befüllt werden, was bedeutet, daß über einen längeren Zeitraum hinweg mehr Filterbeutel benötigt werden, als bei einer optimalen Befüllung der gerätespezifischen Beutel der Fall wäre.As a result, the filter bags are not properly filled, which means that more filter bags are required over a longer period of time than would be the case with optimal filling of the device-specific bags.

Es kommt dadurch zu einer höheren Umweltbelastung und zu einer höheren Kostenbelastung für den Verbraucher.This results in a higher environmental impact and a higher cost burden for the consumer.

Hinzu kommt, daß im Falle einer schlecht sitzenden Filtertüte Staub in die Umgebung gelangen kann, was Spezialfilter zur Filterung von Feinstaub außer Kraft setzt und für den Benutzer, insbesondere für Hausstauballergiker negative gesundheitliche Folgen haben kann.In addition, in the case of a badly fitting filter bag, dust can get into the environment, which overrides special filters for filtering fine dust and can have negative health consequences for the user, especially for people allergic to house dust.

Aufgabe der Erfindung ist es, sicherzustellen, daß der Staubsauger nicht mit Filterbeuteln betrieben werden kann, die die oben genannten Nachteile verursachen können.The object of the invention is to ensure that the vacuum cleaner cannot be operated with filter bags which can cause the disadvantages mentioned above.

Gelöst ist diese Aufgabe durch die in Anspruch 1 dargelegte Erfindung.This object is achieved by the invention set out in claim 1.

Die Unteransprüche 2 bis 4 stellen vorteilhafte Ausgestaltungen der Erfindung dar.The sub-claims 2 to 4 represent advantageous embodiments of the invention.

Die Vorteile der erfinderischen Lösung liegen insbesondere darin, daß es nicht möglich ist, den Elektrostaubsauger mit einem geräteunspezifischen Filterbeutel zu betreiben, weil in diesem Falle die Filterkassette nicht mit dem Motorgehäuse verriegelbar ist.The advantages of the inventive solution are, in particular, that it is not possible to operate the electric vacuum cleaner with a non-device-specific filter bag, because in this case the filter cassette cannot be locked with the motor housing.

Infolge dessen kann es nicht vorkommen, daß Filterbeutel umvorteilhaft befüllt werden bzw. daß aus dem Gerät austretender Staub die Gesundheit des Benutzers gefährdet.As a result, it cannot happen that filter bags are filled disadvantageously or that dust escaping from the device endangers the health of the user.

Der Gegenstand der Erfindung ist nachstehend anhand eines zeichnerisch veranschaulichten Ausführungsbeispiels näher erläutert.The subject matter of the invention is explained in more detail below on the basis of an illustrative embodiment.

Es zeigt:

  • Fig. 1: Eine Ansicht auf die Bodenplatte eines gerätespezifischen Filterbeutels,
  • Fig. 2: eine Ansicht auf die Bodenplatte eines nicht gerätespezifisch ausgelegten Filterbeutels,
  • Fig. 3: eine Vorderansicht im Schnitt des Fiterbeutelschleppdeckels mit eingelegtem gerätespezifischem Filterbeutel, und
  • Fig. 4: eine der Figur 3 entsprechende Teildarstellung entsprechend Schnittlinie I-I mit eingelegtem nicht gerätespezifischen Filterbeutel.
It shows:
  • 1: A view of the bottom plate of a device-specific filter bag,
  • 2: a view of the base plate of a filter bag not designed for specific devices,
  • Fig. 3: a front view in section of the tote bag lid with an inserted device-specific filter bag, and
  • 4: a partial representation corresponding to FIG. 3 according to section line II with a non-device-specific filter bag inserted.

Bei geschlossenem Filterbeutelzwischenträger (5) auf der Filterkassette (4) tauchen die Führungsnocken (6) und die Sicherungsnocken (7) durch die Greifnischen (2) der Bodenplatte (1) des gerätespezifischen Filterbeutels (3).When the filter bag intermediate carrier (5) on the filter cassette (4) is closed, the guide cams (6) and the safety cams (7) dive through the gripping niches (2) of the base plate (1) of the device-specific filter bag (3).

Die Fangrasten (8) in der Filterkassette (4) bleiben leer.The catches (8) in the filter cassette (4) remain empty.

Wird aber ein Filterbeutel (3) mit einer Bodenplatte (9) mit durchgeführter Wandung (10) eingelegt, werden die Sicherungsnocken (11) durch diese Wandung (10) elastisch in Richtung Filterkassettenwandung (13) gedrückt und die Sicherungsnokken (11) gleiten in die Fangrasten (8). Dadurch kann der Filterbeutelzwischenträger (5) nur bis zu einem Abstand (12) auf die Filterkassette (4) geschwenkt werden.However, if a filter bag (3) with a base plate (9) with a wall (10) is inserted, the safety cams (11) are pressed elastically through this wall (10) in the direction of the filter cassette wall (13) and the safety cams (11) slide into it Snap catches (8). As a result, the intermediate filter bag carrier (5) can only be pivoted onto the filter cassette (4) up to a distance (12).

Die Filterkassette (4) kann nicht mit dem Motorgehäuse verriegelt werden und der Staubsauger nicht betrieben werden. Diese Wirkung ist nicht bildlich dargestellt.The filter cassette (4) cannot be locked to the motor housing and the vacuum cleaner cannot be operated. This effect is not illustrated.
