Abstract

A vacuum cleaner nozzle having at least one suction channel (3) has a flat bearing body (2) arranged behind the suction channel (3) in relation to the operating direction. Provided between the bearing body (2) and the suction channel (3) is a channel (4) serving for the supply of air. The suction channel (3) itself can be connected to a vacuum cleaner via a guide pipe (6) engaging on the upper side (5) of the nozzle housing. In order to achieve a small pushing force in a nozzle of this type, it is proposed that the centre of gravity (7) resulting from the sum and the arrangement of the bearing surfaces (8, 9 and 12, 13) constructed on the suction channel (3) and on the bearing body (2) lies inside the bearing surface of the bearing body (2) and, furthermore, that the line (10) of action of the force acting on the nozzle (1) via the guide pipe (6) engaging in a swivelling manner on the nozzle housing lies at an angle of the guide pipe (6) relative to the horizontal of 30 DEG or greater in the centre of gravity (7) or behind the centre of gravity (7) in relation to the operating direction.

Description

Die Erfindung bezieht sich auf eine Staubsaugerdüse mit mindestens einem Saugkanal, der über ein an der Oberseite des Düsengehäuses angreifendes Führungsrohr mit einem Staubsauger verbindbar ist und die einen in bezug auf die Arbeitsrichtung hinter dem Saugkanal angeordneten flächigen Tragkörper aufweist, wobei zwischen dem Tragkörper und dem Saugkanal ein der Luftzufuhr dienender Kanal vorgesehen ist.The invention relates to a vacuum cleaner nozzle with at least one suction channel, which can be connected to a vacuum cleaner via a guide tube engaging on the top of the nozzle housing and which has a flat supporting body arranged behind the suction channel with respect to the working direction, with between the supporting body and the suction channel an air supply duct is provided.

Eine solche Staubsaugerdüse ist durch die US-PS 2 093 741 bekannt. Bei dieser Düse ist zur Verminderung der Schiebekraft der gesonderte Tragkörper hinter dem Saugkanal angeordnet. Über den zwischen dem Tragkörper und dem Saugkanal bestehenden Kanal kann die Luft zu dem Saugkanal zuströmen, so daß unter dem Tragkörper kein die Düse an die abzusaugende Fläche anpressender Unterdruck entsteht. Für den Anschluß des Führungsrohres ist bei dieser Staubsaugerdüse ein starrer Anschlußstutzen an dem Düsengehäuse angeformt. Eine solche starre Verbindung des Führungsrohres mit dem Düsengehäuse erschwert die Handhabung der Staubsaugerdüse; denn um eine optimale Reinigungswirkung zu erzielen, muß die Düsensohle stets horizontal auf der abzusaugenden Fläche aufliegen. Wegen der starren Verbindung zwischen Führungsrohr und Düsengehäuse muß daher bei der bekannten Staubsaugerdüse das Führungsrohr sehr exakt geführt werden, damit die Düsensohle immer horizontal aufliegt. Dies widerspricht jedoch den Benutzungsgewohnheiten.Such a vacuum cleaner nozzle is known from US Pat. No. 2,093,741. In this nozzle, the separate support body is arranged behind the suction channel to reduce the pushing force. The air can flow to the suction channel via the channel existing between the support body and the suction channel, so that under the support body there is no negative pressure pressing the nozzle onto the surface to be extracted. For the connection of the guide tube, a rigid connecting piece is formed on the nozzle housing in this vacuum cleaner nozzle. Such a rigid connection the guide tube with the nozzle housing complicates the handling of the vacuum cleaner nozzle; because in order to achieve an optimal cleaning effect, the nozzle sole must always rest horizontally on the surface to be vacuumed. Because of the rigid connection between the guide tube and the nozzle housing, the guide tube must therefore be guided very precisely in the known vacuum cleaner nozzle so that the nozzle sole always lies horizontally. However, this contradicts the usage habits.

Es ist bei Staubsaugerdüsen mit zwischen den Tragflächen angeordnetem Saugkanal bekannt (DE-PS 16 28 704), am Düsengehäuse einen mit dem Führungsrohr verbindbaren Saugstutzen anzulenken, so daß trotz einer Schwenkbewegung des Führungsrohres die Düse immer auf der abzusaugenden Fläche horizontal aufliegt. Bei derartigen Düsen strömt die Luft unter den Tragflächen hindurch zum Saugkanal. Hierbei entsteht unter den Tragflächen ein Unterdruck, durch den die Düse stark an die abzusaugende Fläche angepreßt wird. Dies führt wiederum zu einer entsprechend hohen Schiebekraft beim Arbeiten mit einer solchen Düse.It is known in vacuum cleaner nozzles with a suction channel arranged between the wings (DE-PS 16 28 704) to articulate a suction connection which can be connected to the guide tube on the nozzle housing, so that despite a pivoting movement of the guide tube the nozzle always lies horizontally on the surface to be extracted. With such nozzles, the air flows under the wings to the suction channel. This creates a vacuum under the wings, which strongly presses the nozzle against the surface to be extracted. This in turn leads to a correspondingly high pushing force when working with such a nozzle.

Der Erfindung liegt die Aufgabe zugrunde, eine Staubsaugerdüse der eingangs beschriebenen Art so zu gestalten, daß die Düse unabhängig von einer Schwenkbewegung des Führungsrohres beim Saugen zur Erzielung einer optimalen Saugwirkung stets auf der abzusaugenden Fläche horizontal aufliegt und die für eine solche Düse charakteristische geringe Schiebekraft beibehalten wird.The invention has for its object to design a vacuum cleaner nozzle of the type described in such a way that the nozzle, regardless of a pivoting movement of the guide tube during suction, always lies horizontally on the surface to be suctioned to achieve an optimal suction effect and maintain the characteristic low pushing force for such a nozzle becomes.

Die Lösung der gestellten Aufgabe gelingt nach der Er- . findung dadurch, daß der sich aus der Summe und der Anordnung der am Saugkanal und am Tragkörper ausgebildeten Tragflächen ergebende geometrische Schwerpunkt innerhalb der Tragfläche des Tragkörpers liegt und die Wirkungslinie der Kraft, die über das schwenkbar am Düsengehäuse angreifende Führungsrohr auf die Düse wirkt, bei einem Winkel des Führungsrohres gegenüber der Horizontalen von gleich oder größer 30° im Schwerpunkt oder in bezug auf die Arbeitsrichtung hinter dem Schwerpunkt liegt.The task is solved after the Er-. invention in that the resulting from the sum and the arrangement of the wings formed on the suction channel and on the support body geometric center of gravity lies within the wing of the support body and the Line of action of the force which acts on the nozzle via the guide tube pivotably engaging the nozzle housing, at an angle of the guide tube relative to the horizontal of 30 ° or more in the center of gravity or in relation to the working direction behind the center of gravity.

Durch eine solche Ausführungsform der Düse wird erreicht, daß sich die Düse infolge der Saugkraft nicht zu sehr nach vorne neigt und dadurch an der abzusaugenden Fläche festsaugt. Durch ein solches Festsaugen wird einerseits die Reinigungswirkung vermindert und andererseits die Schiebekraft erhöht.With such an embodiment of the nozzle it is achieved that the nozzle does not lean too far forward due to the suction force and thereby suction firmly on the surface to be extracted. Such a firm suction reduces the cleaning effect on the one hand and increases the pushing force on the other hand.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispiels wird die Erfindung nachfolgend näher beschrieben.The invention is described in more detail below on the basis of an exemplary embodiment shown in the drawing.

Es zeigt:

  • Fig. 1 eine Staubsaugerdüse in schematischer Darstellung,
  • Fig. 2 eine Staubsaugerdüse im Schnitt.
It shows:
  • 1 is a schematic representation of a vacuum cleaner nozzle,
  • Fig. 2 is a vacuum cleaner nozzle in section.

Die in der Zeichnung dargestellte Staubsaugerdüse 1 besitzt einen Tragkörper 2, der in bezug auf die Arbeitsrichtung der Düse hinter einem Saugkanal 3 angeordnet ist. Zwischen dem Tragkörper 2 und dem Saugkanal 3 ist ein der Luftzufuhr zum Saugkanal 3 dienender Kanal 4 angeordnet. An der Gehäuseoberseite 5 der Staubsaugerdüse 1 ist ein Führungsrohr 6 angelenkt. Das Führungsrohr 6 ist hohl und kann mit einem Staubsauger verbunden werden. Innerhalb des Düsengehäuses besteht zwischen dem Saugkanal 3 und dem Führungsrohr 6 eine in der Zeichnung nicht dargestellte Saugverbindung.The vacuum cleaner nozzle 1 shown in the drawing has a support body 2, which is arranged behind a suction channel 3 with respect to the working direction of the nozzle. Between the support body 2 and the suction channel 3, a channel 4 serving to supply air to the suction channel 3 is arranged. A guide tube 6 is articulated on the upper side 5 of the vacuum cleaner nozzle 1. The guide tube 6 is hollow and can be connected to a vacuum cleaner. Within the nozzle housing between the suction channel 3 and the guide tube 6 there is a suction connection, not shown in the drawing.

Mit 7 ist der geometrische Schwerpunkt aller Tragflächen der Düse bezeichnet. Die Gesamttragfläche entspricht der Summe der Tragfläche des Tragkörpers 2 und der zu beiden Seiten des Saugkanales 3 vorgesehenen Tragflächen 8 und 9. Die Zuordnung der Tragflächen 8 und 9 des Saugkanales 3 und der Tragfläche des Tragkörpers 2 ist so getroffen, daß der Schwerpunkt 7 innerhalb der Tragfläche des Tragkörpers 2 liegt. Mit einem Pfeil 10 ist ferner die Wirkungslinie der über das Führungsrohr 6 auf die Staubsaugerdüse 1 übertragenen Kraft bezeichnet. Die Zuordnung zwischen dem Schwerpunkt 7 und der Anlenkstelle 11 des Führungsrohres 6 an der Gehäuseoberseite 5 der Staubsaugerdüse 1 ist so getroffen, daß bei einem Winkel von 300 und darüber des Führungsrohres 6 gegenüber der Horizontalen die Wirkungslinie 10 im bzw. in Arbeitsrichtung der Düse gesehen hinter dem Schwerpunkt 7 liegt. Durch diese Zuordnung zwischen der Lage des Schwerpunktes 7 und Lage der Anlenkstelle 11 wird die Gefahr des Nachvornkippens infolge der Saugkraft und das damit verbundene Festsaugen des Saugkanales an der abzusaugenden Fläche verhindert. Damit bleibt die Schiebekraft gering und die Saugwirkung in voller Höhe erhalten.With 7 the geometric center of gravity of all wings of the nozzle is designated. The total wing area corresponds to the sum of the wing area of the supporting body 2 and the wing areas 8 and 9 provided on both sides of the suction channel 3. The assignment of the wings 8 and 9 of the suction channel 3 and the wing of the support body 2 is made so that the center of gravity 7 lies within the wing of the support body 2. The line of action of the force transmitted to the vacuum cleaner nozzle 1 via the guide tube 6 is also indicated by an arrow 10. The association between the center of gravity 7 and the articulation point 11 of the guide tube 6 on the top 5 of the housing of the vacuum cleaner nozzle 1 is such that the line of action 10 is seen in or in the working direction of the nozzle at an angle of 30 ° and above the guide tube 6 with respect to the horizontal is behind focus 7. This association between the position of the center of gravity 7 and the position of the articulation point 11 prevents the risk of tipping forward as a result of the suction force and the associated suction of the suction channel on the surface to be extracted. This means that the pushing force remains low and the suction effect is retained in full.

Bei der in Fig. 2 in konstruktiver Ausführungsform dargestellten Staubsaugerdüse 1 weist der Tragkörper 2 mehrere höhenversetzte Tragflächen 12 und 13 auf. Durch eine solche höhenversetzte Anordnung der Tragflächen 12 und 13 wird eine von der Art des Teppichflors abhängende Eindringtiefe des Saugmundstückes erreicht. Je nach Art des Teppichflors kommen eine oder mehrere der höhenversetzten Tragflächen 12 und 13 auf dem Teppich zur Auflage. Hierdurch wird erreicht, daß die Düse nicht zu tief in den Teppich einsinkt und die Schiebekraft gering bleibt.In the vacuum cleaner nozzle 1 shown in a constructive embodiment in FIG. 2, the supporting body 2 has a plurality of vertically offset supporting surfaces 12 and 13. Such a height-offset arrangement of the wings 12 and 13 achieves a depth of penetration of the suction mouthpiece that depends on the type of carpet pile. Depending on the type of carpet pile, one or more of the vertically offset wings 12 and 13 come to rest on the carpet. This ensures that the nozzle does not sink too deeply into the carpet and the pushing force remains low.

Das aus dem Saugkanal 3 und den zu beiden Seiten angeordneten Tragflächen 8 und 9 bestehende Saugmundstück weist eine vordere Mundstückkante 14 und eine hintere Mundstückkante 15 auf. Die vordere Mundstückkante 14 ist gegenüber der zur abzusaugenden Fläche untersten Tragfläche 12 um das Maß a tiefer angeordnet. In gleicher Weise ist die hintere Mundstückkante 15 um das Maß b tiefer angeordnet. Da das Maß a größer als das Maß b gewählt ist, ergibt sich für die hintere Mundstückkante 15 eine weniger tiefe Anordnung gegenüber der Tragfläche 12. Damit besteht an der hinteren Mundstückkante 15 ein geringerer Strömungswiderstand, der einen erhöhten Luftstrom zur Folge hat. Durch den größeren Luftstrom werden die von der vorderen Mundstückkante mechanisch vom Teppich gelösten Schmutzteilchen sicher erfaßt und abtransportiert. Die unterschiedliche Höhe der beiden Mundstückkanten 14 und 15 führt zu einer Verbesserung der Reinigungswirkung der Düse.The suction mouthpiece consisting of the suction channel 3 and the wings 8 and 9 arranged on both sides has a front mouthpiece edge 14 and a rear mouthpiece edge 15. The front edge 14 of the mouthpiece is arranged lower by a dimension than the lower wing 12, which is to be suctioned off. In the same The rear mouthpiece edge 15 is arranged lower by the dimension b. Since the dimension a is chosen to be larger than the dimension b, the rear mouthpiece edge 15 has a less deep arrangement with respect to the wing 12. This results in a lower flow resistance at the rear mouthpiece edge 15, which results in an increased air flow. Due to the larger air flow, the dirt particles mechanically loosened from the carpet by the front edge of the mouthpiece are reliably captured and removed. The different height of the two mouthpiece edges 14 and 15 leads to an improvement in the cleaning effect of the nozzle.
