Abstract

The invention relates to an electric vacuum cleaner having a filter bag intermediate carrier disposed between a filter cassette arranged above a motor-driven blower and the motor housing. The intermediate carrier is pivotally mounted via a hinge and has guide cams which dip into engaging recesses of a base plate of the filter bag. The vacuum cleaner apparatus can only be operated with filter bags which are specific to this apparatus. Safety cams are formed on the intermediate carrier and follow the inner wall surface of the filter cassette when the intermediate carrier is closed. Catches are formed on the inner wall surface but do not catch the safety cams if an authorized filter bag is placed in the filter cassette. However, if an unauthorized filter bag is placed in the filter cassette, then the structure of this filter bag causes the safety cams to deflect and catch in the catches thereby preventing the operator from completely closing the intermediate carrier on the filter cassette.

Description

Die Erfindung bezieht sich auf einen Filterbeutelzwischenträger zwischen einer oberhalb eines Motorgebläses angeordneten Filterkassette und dem Motorgehäuse.
Der durch ein Scharnier abschwenkbare Filterbeutelzwischenträger weist Führungsnocken auf, welche in Greifnischen einer Bodenplatte eines Filterbeutels eintauchen.The invention relates to a filter bag intermediate carrier between a filter cassette arranged above a motor fan and the motor housing.
The filter bag intermediate carrier, which can be swung out 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-A-37 14773 bekannt, beim Schließen des Filterbeutelzwischenträgers zwei Führungsnocken 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.
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.So far, as known from patent DE-A-37 14773, 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.
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.
Es kommt dadurch zu einer höheren Umweltbelastung und zu einer höheren Kostenbelastung für den Verbraucher.
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.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.
This results in a higher environmental impact and a higher cost burden for the consumer.
In addition, in the case of a badly fitting filter bag, dust can get into the environment, which is what special filters Filtering of fine dust overrides and can have negative health consequences for the user, especially for house dust allergy sufferers.

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.
Die Unteransprüche 2 bis 3 stellen vorteilhafte Ausgestaltungen der Erfindung dar.This object is achieved by the invention set out in claim 1.
The sub-claims 2 to 3 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.
Infolge dessen kann es nicht vorkommen, daß Filterbeutel umvorteilhaft befüllt werden bzw. daß aus dem Gerät austretender Staub die Gesundheit des Benutzers gefährdet.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.
As a result, it cannot happen that filter bags are filled unfavorably 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 with the aid of an exemplary embodiment illustrated in the drawing.

Es zeigt:

A view of the bottom plate of a device-specific filter bag,
Fig. 2:
a view of the bottom plate of a filter bag not designed for specific devices,
Fig. 3:
a front view in section of the Fiter bag drag lid with inserted device-specific filter bag, and
Fig. 4:
a partial representation corresponding to Figure 3 according to section line II with inserted non-device-specific filter bag.

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).
Die Fangrasten (8) in der Filterkassette (4) bleiben leer.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).
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 Sicherungsnocken (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) towards the filter cassette wall (13) and the safety cams (11) slide into the Catches (8).
As a result, the filter bag intermediate 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.

Claims (3)

  1. Electric vacuum cleaner with an intermediate dust bag support (5) between the motor housing and a filter cassette located above the motor fan as well as with a dust bag, whereby the hinge-mounted intermediate dust bag support (5) is equipped with guide cams that are designed to insert into recesses (2) in a floor panel (1) of the dust bag, characterised by the fact that the securing cams (7) are arranged on the support (5) in such a way that when there are recesses (2) they dip through the recesses (2) in the floor plate (1) from the paper-bag side and when closing the support, (5) follow the wall (13) of the filter cassette (4) and slide past the catches (8) provided on same and that when there are no recesses (2), the securing cams (7) are moved in the direction of the filter cassette wall (13) by means of a wall (10) on the floor plate (9) and are designed so as to lock in with the catches (8).
  2. Intermediate dust bag support as per Claim 1 characterised by the fact that the securing cams (7) are out of an elastic material.
  3. Intermediate dust bag support as per Claims 1 and 2 characterised by the fact that the catches (8) are form-closed with the wall (13) of the filter cassette.
