Description

Die Erfindung betrifft einen Staubsauger mit einem im Staubraum eingesetzten Filterbeutel, der eine steife Halteplatte aufweist, die in eine am Staubsaugergehäuse vorgesehene Führung eingesteckt ist und an einem in den Staubraum mündenden Saugstutzen anliegt, an welcher Halteplatte femer in Abstand zu deren in der Gebrauchslage oberen Begrenzungsrand eine Knickrille ausgebildet ist, bei welchem Staubsauger der obere Begrenzungsrand der Halteplatte in den Verschwenkweg einer an dem den Staubraum verschließenden Deckel vorgesehenen, beim Schließen des Deckels über den Begrenzungsrand gleitenden und den durch die Knickrille abgegrenzten Streifen zum Staubraum hin umknickenden Schräge ragt.The invention relates to a vacuum cleaner with a filter bag inserted in the dust chamber, which has a rigid holding plate, which is inserted into a guide provided on the vacuum cleaner housing and bears against a suction nozzle opening into the dust chamber, on which holding plate, furthermore, at a distance from its upper boundary edge in the position of use A kink groove is formed, in which the vacuum cleaner projects the upper boundary edge of the holding plate into the pivoting path of a slant provided on the lid closing the dust chamber, which slides over the boundary edge when the lid is closed and which is delimited by the kink groove and bent towards the dust chamber.

Ein solcher Staubsauger ist durch das DE-GM 84 27 471 bekannt. Durch das Umknicken des durch die Knickrille abgegrenzten Streifens der Halteplatte wird zwar eine Erhöhung der Steifigkeit der Halteplatte erreicht, jedoch ist dadurch allein noch nicht in allen Fällen eine sichere Anlage der Halteplatte am Saugstutzen gewährleistet.Such a vacuum cleaner is known from DE-GM 84 27 471. By bending the strip of the holding plate delimited by the kink groove, an increase in the stiffness of the holding plate is achieved, but this alone does not guarantee that the holding plate will rest securely on the suction nozzle in all cases.

Durch die GB-A-1 211 782 ist ferner ein Staubsauger bekannt, bei dem der Filterbeutel mit einem starren Anschlußflansch versehen ist. Mit diesem Anschlußflansch wird der Filterbeutel in eine weite Führung des Staubsaugergehäuses eingelegt. Infolge der weiten Führung nimmt der Anschlußflansch eine Schräglage ein, in der er mit seiner Einlaßöffnung nicht an dem am Staubsaugergehäuse vorgesehenen Saugstutzen anliegt. Das Andrücken des Anschlußflansches an den Saugstutzen wird beim Schließen des Staubraumdeckels selbsttätig bewirkt. Hierzu ist an dem Deckel ein Druckanschlag vorgesehen, der beim Schließen des Deckels mit seiner schrägen Anlaufkante auf eine an dem starren Anschlußflansch ausgebildete Nase auftrifft und dadurch den Anschlußflansch in seine Betriebslage schwenkt, in der die Einlaßöffnung dann dicht an dem Saugstutzen anliegt.GB-A-1 211 782 also discloses a vacuum cleaner in which the filter bag is provided with a rigid connecting flange. With this connection flange, the filter bag is inserted into a wide guide of the vacuum cleaner housing. As a result of the wide guidance, the connecting flange assumes an inclined position in which its inlet opening does not abut the suction nozzle provided on the vacuum cleaner housing. The connection flange is pressed against the suction nozzle when the dust chamber cover is closed. For this purpose, a pressure stop is provided on the cover, which, when the cover is closed, strikes with its oblique leading edge on a nose formed on the rigid connection flange and thereby swivels the connection flange into its operating position, in which the inlet opening then lies tightly against the suction nozzle.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, einen Staubsauger der eingangs beschriebenen Art so auszubilden, daß sowohl ein selbsttätiges Umknicken des an der Halteplatte abgegrenzten Streifens beim Schließen des Deckels als auch eine zusätzliche Abstützung der Halteplatte gegen den Saugstutzen nach dem Schließen des Deckels erreicht werden.In contrast, the invention has for its object to provide a vacuum cleaner of the type described in such a way that both an automatic buckling of the strip delimited on the holding plate when closing the lid and an additional support of the holding plate against the suction nozzle after closing the lid can be achieved.

Die Lösung der gestellten Aufgabe gelingt nach der Erfindung dadurch, daß an dem Deckel an die Schräge anschließend ein kontinuierlicher, bogenförmiger Übergang zu einer Gegenschräge vorgesehen ist, an der der obere Begrenzungsrand bei geschlossenem Deckel abgestützt ist. Beim Schlie-Ben des Deckels trifft die Schräge auf den oberen Begrenzungsrand der Halteplatte. Die Schräge hat eine solche Neigung, daß sie beim weiteren Schlie-Ben des Deckels über den Begrenzungsrand hinweggleitet und dadurch den Streifen zum Staubraum hin abknickt. Infolge des kontinuierlichen, bogenförmigen Überganges kann der Begrenzungsrand ohne die Gefahr des vorzeitigen Hängenbleibens bis zu Gegenschräge gleiten. Die Gegenschräge ist in ihrer Lage und in ihrer Steilheit vorzugsweise so ausgebildet, daß der obere Begrenzungsrand bei vollständig geschlossenem Deckel infolge der Steilheit der Gegenschräge nicht weiter an dieser entlang gleitet, sondern durch Selbsthemmung an der Gegenschräge in seiner abgestützten Stellung verbleibt. Hierdurch wird von der Gegenschräge eine Andrückkraft auf die Halteplatte ausgeübt, die diese sicher in Anlage an dem Saugstutzen hält.The object is achieved according to the invention in that a continuous, arc-shaped transition to a counter slope is provided on the cover to the slope, on which the upper boundary edge is supported when the cover is closed. When the lid is closed, the bevel meets the upper boundary edge of the holding plate. The slope has such an inclination that when the lid is closed further it slides over the boundary edge and thereby kinks the strip towards the dust space. As a result of the continuous, arched transition, the boundary edge can slide to counter-slopes without the risk of premature snagging. The counter-chamfers are preferably designed in their position and in their steepness so that the upper boundary edge does not slide further along this when the lid is completely closed due to the steepness of the counter-chamfers, but remains in its supported position by self-locking on the counter-chamfers. As a result, a pressure force is exerted by the counter bevel on the holding plate, which holds it securely in contact with the suction nozzle.

Dadurch, daß an dem Deckel zwei die Schräge und Gegenschräge enthaltende Rippen in seitlichem Abstand zueinander vorgesehen sind, wird nicht nur ein gleichmäßiges Andrücken der Halteplatte erreicht, sondern auch verhindert, daß der Deckel des Staubraumes bei nicht ordnungsgemäß in die Führung eingesetzter Halteplatte geschlossen werden kann. Ist nämlich die Halteplatte versehentlich nur auf einer Seite in die Führung eingesteckt, dann hat dies eine leichte Schiefstellung der Halteplatte gegenüber ihrer ordnungsgemäßen Gebrauchslage zur Folge. Der obere Begrenzungsrand trifft dadurch an unterschiedlichen Stellen auf die Schrägen der beiden seitlich beabstandeten Rippen, sodaß der Streifen nicht umgeknickt und der Deckel somit nicht geschlossen werden kann.Characterized in that two ribs containing the bevel and counter-bevel are provided on the cover at a lateral distance from one another, not only a uniform pressing of the holding plate is achieved, but also prevents the lid of the dust chamber from being closed when the holding plate is not properly inserted into the guide . If the holding plate is inadvertently inserted into the guide on only one side, this results in the holding plate being slightly inclined relative to its correct position of use. As a result, the upper boundary edge meets the bevels of the two laterally spaced ribs at different points, so that the strip cannot be bent and the lid cannot be closed.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispieles wird der Anmeldungsgegenstand nachfolgend näher beschrieben. Es zeigt:

  • Fig. 1 einen Staubsauger mit einem im Staubraum eingesetzten Filterbeutel,
  • Fig. 2 eine Draufsicht einer Halteplatte mit dreieckförmiger Knickrille,
  • Fig. 3 eine Draufsicht einer Halteplatte mit bogenförmiger Knickrille,
  • Fig. 4 eine Draufsicht einer Halteplatte, bei der die Knickriite perforiert ist.
The subject of the application is described in more detail below using an exemplary embodiment shown in the drawing. It shows:
  • 1 is a vacuum cleaner with a filter bag used in the dust chamber,
  • 2 is a plan view of a holding plate with a triangular crease groove,
  • 3 is a plan view of a holding plate with an arcuate crease groove,
  • Fig. 4 is a plan view of a holding plate in which the buckling rite is perforated.

Mit 1 ist ein Staubsaugergehäuse bezeichnet, in dessen Staubraum 2 ein Filterbeutel 3 eingesetzt ist. Der Filterbeutel 3 ist mit einer steifen Halteplatte 4 verbunden, die in eine an dem Staubsaugergehäuse 1 vorgesehene Führung 5 eingesteckt ist. Die Halteplatte 4 weist eine Einlaßöffnung 6 auf, mit der sie an einem am Staubsaugergehäuse 1 vorgesehenen Saugstutzen 7 anliegt.1 with a vacuum cleaner housing is designated, in the dust chamber 2 a filter bag 3 is inserted. The filter bag 3 is connected to a rigid holding plate 4, which is inserted into a guide 5 provided on the vacuum cleaner housing 1. The holding plate 4 has an inlet opening 6 with which it bears against a suction nozzle 7 provided on the vacuum cleaner housing 1.

Wie aus den Fig. 2, 3 und 4 zu ersehen ist, weist die Halteplatte 4 in Abstand zu ihrem oberen Begrenzungsrand 8 eine Knickrille 9 auf. Die Knickrille 9 verläuft vorteilhafterweise dach- oder bogenförmig, sodaß sie in der Mitte der Halteplatte 4 ihren größten Abstand zu dem oberen Begrenzungsrand 8 hat.As can be seen from FIGS. 2, 3 and 4, the holding plate 4 has a kink groove 9 at a distance from its upper boundary edge 8. The kink groove 9 advantageously extends in a roof or arc shape, so that it has its greatest distance from the upper boundary edge 8 in the middle of the holding plate 4.

An dem den Staubraum 2 verschließenden Deckel 10 sind in seitlichem Abstand zueinander zwei Rippen 11 angeformt. Die Rippen 11 weisen eine durch eine Schräge 12 und eine Gegenschräge 13 begrenzte Ausnehmung 14 auf. Die Ausnehmung 14 ist so angeordnet, daß deren Schräge 12 beim Schließen des Deckels 10 auf den oberen Begrenzungsrand 8 der Halteplatte 4 auftrifft. Die Steigung der Schräge 12 ist so bemessen, daß diese beim weiteren Schließen des Deckels 10 über den oberen Begrenzungsrand 8 hinweggleitet und dadurch den durch die Knickrille 9 abgegrenzten Streifen zum Staubraum hin umknickt. Im weiteren Verlauf des Schließens des Deckels 10 trifft der obere Begrenzungsrand schließlich auf die Gegenschräge 13, deren Steilheit so gewählt ist, daß der Begrenzungsrand an der Gegenschräge 13 verklemmt und somit bei geschlossenem Deckel 10 an dieser anliegt. Hierdurch wird auf die Halteplatte 4 eine Andrückkraft in Richtung auf den Saugstutzen 7 ausgeübt, sodaß die Halteplatte 4 sicher an dem Saugstutzen 7 anliegt.Two ribs 11 are formed on the cover 10 closing the dust chamber 2 at a lateral distance from one another. The ribs 11 have a recess 14 delimited by a bevel 12 and a counter bevel 13. The recess 14 is arranged such that its bevel 12 strikes the upper boundary edge 8 of the holding plate 4 when the cover 10 is closed. The slope of the bevel 12 is dimensioned such that it is closed when the cover 10 is closed further Upper boundary edge 8 slides away and thereby the strip delimited by the crease 9 folds towards the dust space. In the further course of closing the cover 10, the upper boundary edge finally meets the counter bevels 13, the steepness of which is selected so that the boundary edge jams against the counter bevel 13 and thus bears against the latter when the cover 10 is closed. As a result, a pressure force is exerted on the holding plate 4 in the direction of the suction nozzle 7, so that the holding plate 4 lies securely on the suction nozzle 7.

In der Fig. 1 ist mit gestrichelten Linien die Stellung des Deckels 10 beim Auftreffen auf den oberen Begrenzungsrand 8 der Halteplatte 4 dargestellt. Mit voll ausgezogenen Linien ist die Lage des abgeknickten Streifens bei vollständig geschlossenem Deckel 10 verdeutlicht.In Fig. 1, the position of the cover 10 is shown in dashed lines when it hits the upper boundary edge 8 of the holding plate 4. The position of the bent strip when the cover 10 is completely closed is illustrated with solid lines.

Infolge des dach- oder bogenförmigen Verlaufs der Knickrille 9 ergibt sich in der Mitte der Halteplatte 4 eine höhere Andrückkraft, sodaß die Halteplatte 4 im Bereich ihrer Einlaßöffnung 6 verstärkt gegen den Saugstutzen 7 gedrückt wird. Ist die Knickrille nach Art einer Perforierung mit Löchern 15 versehen, dann wird hiedurch das Umknicken des durch die Knickrille 9 abgegrenzten Streifens erleichtert, ohne daß die für das Andrücken der Halteplatte 4 notwendige Steifigkeit des Streifens vermindert wird.As a result of the roof-shaped or arch-shaped course of the kink groove 9, a higher pressing force results in the middle of the holding plate 4, so that the holding plate 4 is pressed increasingly against the suction nozzle 7 in the region of its inlet opening 6. If the kink groove is provided with holes 15 in the manner of a perforation, then this is facilitated by the bending of the strip delimited by the kink groove 9 without reducing the stiffness of the strip which is necessary for pressing on the holding plate 4.
