Abstract

1. A vacuum cleaner mouthpiece (1; 13) for carpets, in which the edges (4, 5; 17, 18) of the suction opening (3; 14) are spaced from a separate supporting body (2; 12) which supports the mouthpiece of the vacuum cleaner on the carpet, said edges being lower than the contact surface (19) of the supporting body, characterized in that the supporting bocy (2; 12) extends over the entire width of the mouthpiece and has a plurality of contact surfaces (7, 8) which are stepped as regards height, and that the edge (4; 17) of the suction opening (3; 14) which is at the front in the operating direction of the vacuum cleaner mouthpiece (1; 13) is arranged to be lower than the rear edge (5; 18).

Description

Die Erfindung bezieht sich auf eine Staubsaugerdüse, die einen gegenüber dem Saugmundstück gesondert angeordneten Tragkörper aufweist und bei der die Mundstückkanten des Saugmundstückes gegenüber der Tragflächenebene des Tragkörpers tiefer angeordnet sind.The invention relates to a vacuum cleaner nozzle which has a support body which is arranged separately from the suction mouthpiece and in which the mouthpiece edges of the suction mouthpiece are arranged lower relative to the wing plane of the support body.

Eine solche Staubsaugerdüse ist durch die US-PS 1020104 bekannt. Bei dieser Düse weist der Tragkörper eine relativ kleine Tragfläche auf, wobei der Tragkörper in eine vor und eine hinter dem Saugmundstück liegende Tragfläche unterteilt ist. Die Mundstückkanten des Saugmundstückes liegen in einer Ebene und sind gegenüber der Tragfläche etwas tiefer angeordnet. Durch die kleine Tragfläche bedingt, sinkt die Düse auf weichen (langflorigen) Teppichen tief ein, wodurch eine starke Erhöhung der Schiebekraft eintritt. Durch das tiefe Einsinken besteht die Gefahr, daß der Saugschlitz des Saugmundstückes zu stark von dem Teppichflor verschlossen und dadurch die angesaugte Luftmenge stark gedrosselt wird, so daß sich die Düse am Teppichgrund festsaugt. Damit kann die Düse überhaupt nicht mehr weiterbewegt werden und es wird die Reinigungswirkung vermindert. Durch die vor dem Saugmundstück angeordnete Tragfläche kann frontal nicht bis an eine Wand abgesaugt werden.Such a vacuum cleaner nozzle is known from US-PS 1020104. In this nozzle, the support body has a relatively small support surface, the support body being subdivided into a support surface located in front of and behind the suction nozzle. The mouthpiece edges of the suction mouthpiece lie in one plane and are arranged somewhat lower than the wing. Due to the small wing, the nozzle sinks deep into soft (long-pile) carpets, causing a strong increase in pushing force. Due to the deep sinking in, there is a risk that the suction slot of the suction mouthpiece will be too tightly closed by the carpet pile, and the amount of air sucked in will be severely restricted, so that the nozzle will suck onto the carpet base. So that No longer move the nozzle at all and the cleaning effect is reduced. Due to the wing arranged in front of the suction mouthpiece, it is not possible to suction up to a wall from the front.

Durch die US-PS.2 540 917 ist ein Bürststaubsauger bekannt, bei dem das vordere Räderpaar aus jeweils drei Rädern mit unterschiedlichem Durchmesser besteht. Je nachdem, ob mit einem solchen Bürststaubsauger auf einem festen oder weichen Teppich gesaugt wird, sinken die Räder entsprechend in den Teppich ein und damit auch das vor den Rädern angeordnete, mit einer rotierenden Bürste versehene Saugmundstück. Die Mundstückkanten liegen in einer Ebene und sind gegenüber der Tragfläche der Räder höher angeordnet. Die Bürste selbst ragt mit ihren Borstenreihen aus dem Saugmundstück hervor. Durch das verschieden tiefe Einsinken der Räder wird erreicht, daß bei einem langflorigen Teppich die Bürste noch tief genug in den Teppichflor eindringt und damit auch noch am Grund des Teppichflors eine Reinigung erfolgt. Die Reinigungswirkung wird durch die den Teppichflor bearbeitende Bürste erzielt. Der Saugstrom dient lediglich zum Abtransport des durch die Bürste gelösten Schmutzes.A brush vacuum cleaner is known from US Pat. No. 2,540,917, in which the front pair of wheels consists of three wheels each with a different diameter. Depending on whether a brush vacuum cleaner of this type is used to vacuum on a firm or soft carpet, the wheels sink accordingly into the carpet and thus also the suction nozzle arranged in front of the wheels and provided with a rotating brush. The mouthpiece edges lie in one plane and are arranged higher than the wing surface. The bristle rows of the brush itself protrude from the suction nozzle. The sinking in of the wheels to different depths ensures that in the case of a long-pile carpet, the brush penetrates deep enough into the carpet pile and thus also is cleaned at the bottom of the carpet pile. The cleaning effect is achieved by the brush processing the carpet pile. The suction flow only serves to remove the dirt loosened by the brush.

Weiterhin ist durch die US-PS 2 093 741 eine Staubsaugerdüse mit einem hinter dem Saugmundstück angeordneten und sich über die ganze Düsenbreite erstreckenden Tragkörper bekannt. Die Mundstückkanten des Saugmundstückes liegen in einer Ebene, die mit der Tragflächenebene des Tragkörpers auf gleicher Höhe liegt. Das Saugmundstück kann daher gegenüber dem Tragkörper nicht tiefer in den Teppich eindringen, wodurch keine optimale Reinigungswirkung erzielt wird.Furthermore, US Pat. No. 2,093,741 discloses a vacuum cleaner nozzle with a support body which is arranged behind the suction nozzle and extends over the entire width of the nozzle. The mouthpiece edges of the suction mouthpiece lie in a plane which is at the same height as the wing plane of the support body. The suction mouthpiece can therefore not penetrate deeper into the carpet than the supporting body, as a result of which an optimal cleaning effect is not achieved.

Der Erfindung liegt die Aufgabe zugrunde, eine Staubsabagerdüse so auszubilden daß bei der Reinigung von Teppichen verschiedener Art die zum Bewegen der Düse notwendige Schiebekraft möglichst gering und ein zur Erzielung einer guten Reinigungswirkung ausreichend tiefes Eindringen des Saugmundstückes ohne die Gefahr des Festsaugens möglich ist.The invention has for its object to form a dust collector nozzle so that when cleaning carpets Chen various types, the pushing force required to move the nozzle is as low as possible and penetration of the suction mouthpiece sufficiently deep to achieve a good cleaning effect is possible without the risk of seizing.

Die Lösung der gestellten Aufgabe gelingt nach der Erfindung dadurch, daß sich der Tragkörper über die ganze Düsenbreite erstreckt und mehrere in der Höhe zueinander versetzte Tragflächen aufweist, und daß die vordere Mundstückkante gegenüber der untersten Tragflächenebene tiefer als die hintere Mundstückkante angeordnet ist.The object is achieved according to the invention in that the support body extends over the entire nozzle width and has a plurality of wings offset in height from each other, and that the front edge of the mouthpiece is arranged lower than the rear edge of the mouthpiece relative to the lowest level of the wing surface.

Durch die höhenversetzte Anordnung der Tragflächen wird eine von der Art des Teppichflors abhängende Eindringtie-fe des Saugmundstückes erreicht. Je nachdem, ob der Teppich einen härteren oder weicheren bzw. kürzeren oder la geren Flor besitzt, kommen eine oder mehrere der höhenversetzten Tragflächen mit dem Teppich in Ringriff. Bei einer sehr weichen Teppichflor wird die Staubsaugerdüse soweit in den Flor einsinken, bis alle Tragflächen zum Tragen kommen. Die Größe der Tragflächen ist so bemessen, daß die Düse zur Vermeidung einer zu hohen Schiebekraft nicht zu tief in den Teppich einsinkt. Da die vordere Mundstückkan te gegenüber der hinteren Mundstückkante tiefer angeordne ist, kann über die hintere Mundstückkante auch bei einem Aufliegen der vorderen Mundstückkante auf dem Teppichgrund noch Luft zuströmen, so daß ein Festsaugen der Düse nicht mehr möglich ist. Die unterschiedlich tiefe Anordnung der Mundstückkanten ergibt an der hinteren Mundstückkante einen geringeren Strömungswiderstand, so daß eine größere Luftmenge über diese hintere Mundstückkante in den Saugkanal eintritt, durch die die von der vorderen Mundstück kante gelösten Schmutzteile sicher erfaßt und

tiert werden.Due to the height-offset arrangement of the wings, a penetration depth of the suction mouthpiece depending on the type of carpet pile is achieved. Depending on whether the carpet has a harder or softer or a shorter or longer pile, one or more of the vertically offset wings come into ring reef with the carpet. If the carpet is very soft, the vacuum cleaner nozzle will sink into the pile until all the wings come into play. The size of the wings is such that the nozzle does not sink too deep into the carpet to avoid excessive pushing force. Since the front mouthpiece edge is arranged lower than the rear edge of the mouthpiece, air can still flow in via the rear edge of the mouthpiece even when the front edge of the mouthpiece rests on the carpet base, so that it is no longer possible to suck the nozzle firmly. The different depth arrangement of the mouthpiece edges results in a lower flow resistance at the rear mouthpiece edge, so that a larger amount of air enters the suction channel via this rear mouthpiece edge, through which the dirt particles detached from the front mouthpiece edge are reliably detected and

be animals.

Ein frontales Randsaugen läßt sich in bekannter Weise dadurch erreichen, daß der Tragkörper in Arbeitsrichtung hinter dem Saugmundstück angeordnet ist.A frontal edge suction can be achieved in a known manner in that the support body is arranged behind the suction mouthpiece in the working direction.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispieles wird der Anmeldungsgegenstand nachfolgend näher beschrieben.The subject of the application is described in more detail below using an exemplary embodiment shown in the drawing.

Es zeigt:

  • Figur 1 eine Draufsicht der Unterseite der Staubsaugerdüse,
  • Figur 2 eine Staubsaugerdüse im Schnitt entlang der Linie II-II in Figur 1,
  • Figur 3 eine Staubsaugerdüse mit gegenüber der Tragfläche unterschiedlich tief angeordneten Mundstückkanten im Querschnitt.
It shows:
  • FIG. 1 shows a top view of the underside of the vacuum cleaner nozzle,
  • FIG. 2 shows a vacuum cleaner nozzle in section along the line II-II in FIG. 1,
  • FIG. 3 shows a cross section of a vacuum cleaner nozzle with a mouthpiece edge arranged at different depths with respect to the wing.

In Figur 1 ist mit 1 ein Saugmundstück bezeichnet, das mit einem gesonderten Tragkörper 2 verbunden ist. Das Saugmundstück 2 besitzt einen Saugkanal 3, der durch die Mundstückkanten 4 und 5 begrenzt wird. Der Saugkanal 3 steht mit einer Absaugöffnung 6 in Saugverbindung. Der Tragkörper 2 weist eine erste, aus Teilflächen 7 bestehende Tragfläche auf. Gegenüber dieser ersten Tragfläche ist eine zweite Tragfläche 8 vorgesehen, die gegenüber der ersten Tragfläche 7 in der Höhe versetzt ist. Die erste Tragfläche 7 bildet die gegenüber der abzusaugenden Fläche unterste Tragflächenebene.In Figure 1, 1 designates a suction mouthpiece, which is connected to a separate support body 2. The suction mouthpiece 2 has a suction channel 3 which is delimited by the mouthpiece edges 4 and 5. The suction channel 3 is in suction connection with a suction opening 6. The support body 2 has a first support surface consisting of partial surfaces 7. Opposite this first wing, a second wing 8 is provided which is offset in height from the first wing 7. The first aerofoil 7 forms the lowest aerofoil level relative to the surface to be extracted.

Wie die Darstellung nach Figur 2 zeigt, ist das Saugmundstück 1 gegenüber dem Tragkörper 2 tiefer angeordnet. Hierdurch ist bereits eine bestimmte Eindringtiefe vorgegeben. Beim Absaugen eines Teppichs mit festerem Flor reichen bereits die Teilflächen der ersten Tragfläche 7 aus, um die Staubsaugerdüse auf dem Teppich zu tragen. Besitzt der Teppich hingegen einen weicheren Flor, so sinken die Teilflächen der ersten Tragfläche 7 tiefer in den Teppich ein, so daß auch noch die zweite Tragfläche 8 zum Tragen kommt. Hierdurch dringt dann auch das Saugmundstück 1 tiefer in den Flor ein und vermag den Schmutz aus den Tiefen des Teppichs herauszuholen. Durch die höhenversetzte Anordnung der Tragflächen 7 und 8 wird erreicht, daß das Saugmundstück 1 je nach Art des Teppichs verschieden tief in den Flor eindringt. Dabei wird ein die Schiebekraft erhöhendes, zu tiefes Eindringen durch die entsprechend wirksam werdenden Tragflächen verhindert.As the illustration according to FIG. 2 shows, the suction mouthpiece 1 is arranged lower than the supporting body 2. As a result, a certain depth of penetration is already predetermined. When vacuuming a carpet with a firmer pile, the partial surfaces of the first wing 7 are sufficient to carry the vacuum cleaner nozzle on the carpet. However, if the carpet has a softer pile, then the partial surfaces of the first wing 7 sink deeper into the carpet, so that the second wing 8 also comes into play. As a result, the suction mouthpiece 1 then penetrates deeper into the pile and is able to remove the dirt from the depths of the carpet. The height-offset arrangement of the wings 7 and 8 ensures that the suction mouthpiece 1 penetrates into the pile at different depths, depending on the type of carpet. In this way, penetration that increases the pushing force and is penetrated too deeply is prevented by the correspondingly effective wings.

Die in Figur 3 dargestellte Staubsaugerdüse 11 besitzt einen Tragkörper 12, mit dem ein Saugmundstück 13 verbunden ist. Das Saugmundstück 13 enthält einen sich quer zur Arbeitsrichtung erstreckenden Saugkanal 14, der über eine Saugöffnung 15 mit dem Saugstutzen 16 der Staubsaugerdüse 11 in Verbindung steht. An den Saugstutzen 16 ist über ein Saugrohr oder einen Saugschlauch ein Staubsauger anschließbar. Der Saugkanal 14 besitzt eine vordere Mundstückkante 17 und eine hintere Mundstückkante 18. Die vordere Mundstückkante 17 ist gegenüber der Auflageebene 19, welche die gegenüber der abzusaugenden Fläche unterste Tragflächenebene des Tragkörpers 12 darstellt, um das Maß a und die hintere Mundstückkante 18 um das Maß b tiefer angeordnet. Das Maß a ist größer als das Maß b gewählt.The vacuum cleaner nozzle 11 shown in Figure 3 has a support body 12 to which a suction nozzle 13 is connected. The suction mouthpiece 13 contains a suction channel 14 which extends transversely to the working direction and is connected to the suction nozzle 16 of the vacuum cleaner nozzle 11 via a suction opening 15. A vacuum cleaner can be connected to the suction nozzle 16 via a suction pipe or a suction hose. The suction channel 14 has a front mouthpiece edge 17 and a rear mouthpiece edge 18. The front mouthpiece edge 17 is opposite the support plane 19, which represents the lowest wing plane of the support body 12 relative to the surface to be suctioned, by the dimension a and the rear mouthpiece edge 18 by the dimension b arranged lower. Dimension a is larger than dimension b.

Beim Absaugen eines langflorigen Teppichs kann das Saugmundstück 13 tief in den Teppichflor eindringen und somit den Schmutz besser absaugen. Durch die vordere Mundstückkante 17 wird hierbei der Schmutz mechanisch von dem Teppichflor gelöst. Da die hintere Mundstückkante 18 gegenüber der vorderen Mundstückkante 17 zurückgesetzt ist, kann die Luft über diese hintere Mundstückkante 18 besser in den Saugkanal 14 einströmen. Durch den über die hintere Mundstückkante 18 eintretenden Luftstrom werden die von der vorderen Mundstückkante 17 gelösten Schmutzpartikel mitgerissen und in den Staubsauger transportiert, so daß sich eine bessere Reinigungswirkung ergibt.When vacuuming a long-pile carpet, the suction mouthpiece 13 can penetrate deeply into the carpet pile and thus better suck off the dirt. The dirt is loosened mechanically from the carpet pile by the front edge 17 of the mouthpiece. Since the rear mouthpiece edge 18 is set back from the front mouthpiece edge 17, the air can flow better into the suction channel 14 via this rear mouthpiece edge 18. Due to the air stream entering through the rear mouthpiece edge 18, the dirt particles loosened from the front mouthpiece edge 17 are entrained and transported into the vacuum cleaner, so that there is a better cleaning effect.
