Description

Die Erfindung betrifft ein Staubsaugermundstück gemäß dem Oberbegriff des Anspruches 1.The invention relates to a vacuum cleaner nozzle according to the preamble of claim 1.

Ein solches Staubsaugermundstück ist durch die DE-A-195 28 768 bekannt. Um auf unterschiedlichen Bodenbelägen, z.B. Hartboden, lang- oder kurzflorigen Teppichen, gute Reinigungsergebnisse zu erzielen, müssen die auf dem abzusaugenden Bodenbelag aufliegende Fläche und der Saugkanal des Staubsaugermundstückes entsprechend gestaltet sein. Bei dem bekannten Staubsaugermundstück ist daher an der Mundstückunterseite ein verstellbares Zusatzteil angebracht, welches entsprechend der Beschaffenheit der abzusaugenden Fläche verstellt werden kann. Damit kann in Abhängigkeit von der Art der abzusaugenden Bodenfläche zumindest die Auflagefläche des Staubsaugermundstückes so verändert werden, daß ein möglichst gutes Reinigungsergebnis erzielt wird. Der Saugkanal selbst bleibt unverändert, so daß das Reinigungsergebnis nicht optimal sein kann.Such a vacuum cleaner mouthpiece is known from DE-A-195 28 768. To be used on different floor coverings, e.g. Hard floor, long- or short-pile carpets, to achieve good cleaning results, the resting on the floor to be vacuumed surface and the suction channel of the vacuum cleaner mouthpiece must be designed accordingly. In the known Staubsaugermundstück therefore an adjustable additional part is attached to the mouthpiece underside, which can be adjusted according to the nature of the surface to be sucked. Thus, depending on the type of floor area to be vacuumed, at least the contact surface of the vacuum cleaner mouthpiece can be changed so that the best possible cleaning result is achieved. The suction channel itself remains unchanged, so that the cleaning result can not be optimal.

Aus der US 1 533 368, der CH 247 214 sowie aus der EP 0 194 107 sind verschiedene Staubsaugermundstücke bekannt. Des weiteren ist aus der DE-OS 20 52 606 eine Staubsaugerdüse mit zwei getrennten Luftführungen mit verschiedenen Ansaugquerschnitten bekannt. Die zwei Luftführungen sind wechselweise mit einer Ansaugöffnung eines Saugstutzens verbindbar. Die eine Luftführung mit großem Ansaugquerschnitt dient zum Absaugen von Flächen. Die zweite Luftführung weist einen schlitzförmigen Ansaugquerschnitt zum Reinigen von Polsterfugen auf.Various vacuum cleaner mouthpieces are known from US 1 533 368, CH 247 214 and EP 0 194 107. Furthermore, from DE-OS 20 52 606 a vacuum cleaner nozzle with two separate air ducts with different Ansaugquerschnitten known. The two air ducts are alternately connectable to a suction port of a suction nozzle. The one air duct with a large intake cross section is used to extract surfaces. The second air duct has a slot-shaped Ansaugquerschnitt for cleaning upholstery joints.

Der Erfindung liegt die Aufgabe zugrunde, ein Staubsaugermundstück der eingangs beschriebenen Art so auszubilden, daß bei den unterschiedlichsten Bodenbelägen stets eine optimale Reinigungswirkung erzielt wird.The invention has the object of providing a vacuum cleaner mouthpiece of the type described above in such a way that always an optimal cleaning effect is achieved in a variety of floor coverings.

Die Lösung der gestellten Aufgabe gelingt nach der Erfindung dadurch, daß an dem Mundstückteil mehrere, für das Saugen auf unterschiedlichen Bodenbelägen speziell angepaßte Saugkanäle vorgesehen sind, die strömungsmäßig wahlweise mit dem Saugstutzen koppelbar sind. Die einzelnen Saugkanäle können in ihrer Geometrie jeweils so gestaltet werden, daß sich bei dem entsprechend zugeordneten Bodenbelag ein optimales Reinigungsergebnis einstellt. Dabei ist die beim Einsatz des jeweiligen Saugkanales wirksame Auflagefläche des Staubsaugermundstückes ebenfalls für die Erzielung eines optimalen Reinigungsergebnisses entsprechend angepaßt.The solution of the object is achieved according to the invention in that a plurality, for sucking on different floor coverings specially adapted suction channels are provided on the mouthpiece part, which can be coupled in terms of flow optionally with the suction nozzle. The individual suction channels can each in their geometry be designed so that sets an optimal cleaning result in the correspondingly assigned flooring. It is the when using the respective suction channel effective contact surface of the vacuum cleaner mouthpiece also adapted to achieve an optimal cleaning result accordingly.

Die saugmäßige Aktivierung eines für einen bestimmten Bodenbelag speziell gestalteten Saugkanales wird auf einfache Weise dadurch erreicht, daß das Mundstückteil um eine senkrechte Achse drehbar mit dem mit dem Saugstutzen versehenen Gehäuseoberteil verbunden und jeweils in einer der Arbeitsrichtung des jeweiligen Saugkanales entsprechenden Stellung blockierbar ist. Mittels eines an dem Saugstutzen angeschlossenen Saugrohres kann eine Verschwenkbewegung auf das Gehäuseoberteil ausgeübt werden, bis dieses in einer der Arbeitsrichtung des gewünschten Saugkanales entsprechenden Stellung mit dem Mundstückteil verrastet, so daß beim Arbeiten mit dem Staubsaugermundstück diese Stellung beibehalten wird.The suction-like activation of a specially designed for a particular flooring suction channel is achieved in a simple manner that the mouthpiece part rotatably connected about a vertical axis with the suction nozzle provided with the upper housing and each in a working direction of the respective suction channel corresponding position can be blocked. By means of a suction pipe connected to the suction pipe, a pivoting movement can be exerted on the upper housing part, until it engages in a working direction of the desired suction channel corresponding position with the mouthpiece part, so that when working with the vacuum cleaner mouth this position is maintained.

Für das Saugen auf einem harten Bodenbelag läßt sich die Auflagefläche des Mundstückteiles auf einfache Weise dadurch anpassen, daß an dem Mundstückteil Tragelemente vorgesehen sind, die durch das gegenseitige Verschwenken von Mundstückteil und Gehäuseoberteil beim saugmäßige Aktivieren von zumindest einem der Saugkanäle in eine über die normale Auflageebene des Mundstückteiles vorragende Stellung bringbar sind. Somit wird beim Umstellen des Staubsaugermundstückes auf den für harten Bodenbelag am besten geeigneten Saugkanal ohne einen zusätzlichen Umschaltvorgang gleichzeitig die Auflagefläche der Mundstückunterseite entsprechend der Art des Bodenbelages angepaßt. Zweckmäßigerweise sind als Tragelemente Borstenleisten an der Mundstückunterseite vorgesehen. Anstelle von Borstenleisten können auch in ihrer Höhenlage gegenüber der Mundstückunterseite verstellbar angeordnete Roll- oder Gleitkörper zum Einsatz kommen.For sucking on a hard floor covering, the support surface of the mouthpiece part can be adapted in a simple manner by providing support elements on the mouthpiece part, which by the mutual pivoting of the mouthpiece part and the housing upper part during suction activation of at least one of the suction channels into one over the normal support plane the mouthpiece part projecting position can be brought. Thus, the support surface of the mouthpiece bottom is adapted according to the type of flooring at the same time when switching the vacuum cleaner mouthpiece on the most suitable for hard flooring suction channel without an additional switching operation. Appropriately, bristle strips are provided on the mouthpiece underside as support elements. Instead of bristle strips can also be used in their altitude relative to the mouthpiece underside adjustable arranged rolling or sliding bodies are used.

Eine für die meisten Saugarbeiten ausreichende Anzahl von Einstellmöglichkeiten ist dadurch gegeben, daß an dem Mundstückteil drei in Dreieckform angeordnete Saugkanäle vorgesehen sind. Ein solches Staubsaugermundstück kann dann entsprechend der drei am häufigsten vorkommenden Bodenbelagsarten, nämlich harte und/oder glatte Böden, Textilbodenbeläge mit lockerem und/oder langem Flor sowie Beläge mit festem und/oder kurzem Flor, jeweils für eine optimale Reinigung eingestellt werden.A sufficient number of adjustment options for most of the suction work is provided by the fact that three suction channels arranged in triangular form are provided on the mouthpiece part. Such a vacuum cleaner mouthpiece can then be adjusted according to the three most common types of flooring, namely hard and / or smooth floors, textile floor coverings with loose and / or long pile and coverings with firm and / or short pile, each for optimum cleaning.

Bei einem solchen dreieckförmigen Staubsaugermundstück ist es besonders vorteilhaft, daß eine Borstenleiste mit Bezug auf die Arbeitsrichtung des Staubsaugermundstückes hinter einem der Saugkanäle zu diesem parallel verlaufend angeordnet ist und eine weitere senkrecht zu der einen Borstenleiste ausgerichtete Borstenleiste im Bereich der dem betreffenden Saugkanal gegenüberliegenden Dreieckspitze des Mundstückunterteiles vorgesehen ist. Auf diese Weise wird eine relativ stabile Abstützung des Staubsaugermundstückes mittels der Borstenleisten beim Saugen auf glatten und harten Böden erzielt.
Bei einer weiteren Ausführungsform des Staubsaugermundstückes ist der Mundstückteil als ein mit mehreren Saugkanälen versehener Walzenkörper ausgebildet, der drehbar im Mundstückgehäuse angeordnet ist, wobei die Saugkanäle durch entsprechendes Verdrehen des Walzenkörpers strömungsmäßig mit dem Verbindungskanal koppelbar sind.In such a triangular vacuum cleaner mouthpiece, it is particularly advantageous that a bristle strip with respect to the working direction of the vacuum cleaner mouth behind one of the suction channels is arranged to run parallel to this and another perpendicular to the bristle strip aligned bristle strip in the region of the respective suction channel opposite the triangle tip of the mouthpiece is provided. In this way, a relatively stable support of the vacuum cleaner mouthpiece is achieved by means of bristle strips when sucking on smooth and hard floors.
In a further embodiment of the vacuum cleaner mouthpiece, the mouthpiece part is designed as a roller body provided with a plurality of suction channels, which is rotatably arranged in the mouthpiece housing, wherein the suction channels can be fluidly coupled to the connection channel by corresponding rotation of the roller body.

Mit 1 ist ein Mundstückteil eines Staubsaugermundstückes 2 bezeichnet. Das Mundstückteil 1 ist dreieckförmig ausgebildet und drehbar auf einem senkrecht stehenden Achszapfen 3 eines Gehäuseoberteiles 4 angeordnet. An dem Gehäuseoberteil 4 befindet sich ein Saugstutzen 5 an dem ein mit einem Staubsauger saugmäßig gekoppeltes Saugrohr 6 angesteckt werden kann. Von dem Saugstutzen 5 ausgehend führt im Inneren des Gehäuseoberteiles 4 ein Verbindungskanal 7 zur Vorderseite des Staubsaugermundstückes 2.1 with a mouthpiece part of a vacuum cleaner mouthpiece 2 is designated. The mouthpiece part 1 is triangular in shape and rotatably mounted on a vertical journal 3 of a housing upper part 4. On the upper housing part 4 there is a suction nozzle 5 to which a suction pipe 6 suction-coupled with a vacuum cleaner can be connected. Starting from the suction nozzle 5, a connecting channel 7 leads to the front side of the vacuum cleaner mouthpiece 2 in the interior of the housing upper part 4.

An dem Mundstückteil 1 sind ein erster, zweiter und dritter Saugkanal 8,9 und 10 ausgebildet. Die drei Saugkanäle 8-10 verlaufen im wesentlichen parallel zu den drei Seiten des Mundstückteiles 1. Der erste Saugkanal 8 ist dabei speziell für Saugarbeiten auf harten bzw. glatten Böden ausgestaltet. Dementsprechend ist mit Bezug auf die Arbeitsrichtung des Staubsaugermundstückes hinter dem ersten Saugkanal 8 eine Borstenleiste 11 angeordnet. Eine weitere Borstenleiste 12 ist senkrecht zu der einen Borstenleiste 11 ausgerichtet und im Bereich der dem ersten Saugkanal 8 gegenüberliegenden Dreiecksspitze 13 angebracht. Wie aus der Fig. 2 erkennbar, ist die eine Borstenleiste 11 am freien Ende eines verschwenkbar gelagerten Hebelarmes 14 befestigt. Werden zum saugmäßigen Aktivieren des ersten Saugkanales 8 das Mundstückteil 1 und das Gehäuseoberteil 4 entsprechend gegeneinander verschwenkt, dann trifft ein am Gehäuseoberteil 4 vorgesehener Nocken 15 auf den Hebelarm 14 und verschwenkt diesen entsprechend, so daß die am freien Ende des Hebelarmes 14 befestigte eine Borstenleiste 11 gegenüber der normalen Auflageebene 16 des Mundstückteiles 1 vorspringt. Gleichzeitig mit der einen Borstenleiste 11 wird auch die weitere Borstenleiste 12 beim Verschwenken des Mundstückteiles 1 und des Gehäuseoberteiles 4 derart verstellt, daß auch sie gegenüber der normalen Auflageebene 16 des Mundstückteiles 1 vorspringt. Damit übernehmen die beiden Borstenleisten 11 und 12 die Tragfunktion für das Staubsaugermundstück 2.At the mouthpiece part 1, a first, second and third suction channel 8,9 and 10 are formed. The three suction channels 8-10 extend substantially parallel to the three sides of the mouthpiece part 1. The first suction channel 8 is designed specifically for suction on hard or smooth floors. Accordingly, with respect to the working direction of the vacuum cleaner nozzle behind the first suction channel 8, a bristle strip 11 is arranged. Another bristle strip 12 is aligned perpendicular to the one bristle strip 11 and attached in the region of the first suction channel 8 opposite triangular tip 13. As can be seen from FIG. 2, one bristle strip 11 is fastened to the free end of a pivotably mounted lever arm 14. If the mouthpiece part 1 and the upper housing part 4 are swiveled correspondingly to each other for suction-activated activation of the first suction channel 8, then a cam 15 provided on the upper housing part 4 strikes the lever arm 14 and pivots it accordingly, so that the bristle strip fastened to the free end of the lever arm 14 opposite the normal support plane 16 of the mouthpiece part 1 protrudes. Simultaneously with the one bristle strip 11 and the other bristle strip 12 is adjusted during pivoting of the mouthpiece part 1 and the upper housing part 4 such that it also protrudes from the normal support plane 16 of the mouthpiece part 1. Thus, the two bristle strips take over 11 and 12, the support function for the vacuum cleaner mouthpiece. 2

Der zweite Saugkanal 9 ist speziell für das Absaugen von lockeren bzw. langflorigen Teppichen ausgebildet. Seine Geometrie ist so gestaltet, daß bei einer solchen Teppichart möglichst optimale Reinigungsergebnisse erzielt werden. Dabei ist auch noch auf die Einhaltung einer angemessenen Schiebekraft geachtet. Zu beiden Längsseiten des zweiten Saugkanales 9 sind noch Fadenheber 17 angeordnet.The second suction channel 9 is specially designed for the extraction of loose or long-pile carpets. Its geometry is designed so that the best possible cleaning results are achieved in such a carpet. It is also paid attention to the observance of an appropriate pushing force. On both longitudinal sides of the second suction channel 9 still thread lifter 17 are arranged.

Der dritte Saugkanal 10 ist schließlich für das Absaugen von festen bzw. kurzflorigen Teppichen ausgelegt. Diesem Saugkanal 10 ist auf der einen Längsseite ebenfalls ein Fadenheber 17 zugeordnet. Es besteht auch die Möglichkeit zu beiden Längsseiten diese Saugkanales 10 Fadenheber 17 anzubringen.The third suction channel 10 is finally designed for the extraction of solid or kurzflorigen carpets. This suction channel 10 is also associated with a thread lifter 17 on one longitudinal side. There is also the possibility to attach both sides of this suction channel 10 thread lifter 17.

Beim saugmäßigen Aktivieren eines der drei Saugkanäle 8 bzw. 9 bzw. 10 durch entsprechendes Verschwenken vom Mundstückteil 1 und Gehäuseoberteil 4 wird der betreffende Saugkanal 8 bzw. 9 bzw. 10 über eine Einlaßöffnung 18 des Verbindungskanals 7 an diesen und damit an den Saugstutzen 5 angekoppelt. Damit ist nur jeweils der in Arbeitsrichtung des Staubsaugermundstückes 2 vorne quer liegende Saugkanal 8 bzw. 9 bzw. 10 saugmäßig aktiv. Entsprechend der jeweiligen Beschaffenheit der abzusaugenden Bodenfläche wird der entsprechende Saugkanal 8 bzw. 9 bzw. 10 aktiviert. Damit werden auch bei unterschiedlicher Beschaffenheit der abzusaugenden Bodenflächen optimale Reinigungsergebnisse erzielt, ohne daß hohe Schiebekräfte in Kauf genommen werden müssen.When Saugaug activate one of the three suction channels 8 and 9 or 10 by appropriate pivoting of the mouthpiece part 1 and the upper housing part 4 of the relevant Suction channel 8 or 9 or 10 via an inlet port 18 of the connecting channel 7 coupled thereto and thus to the suction nozzle 5. Thus, only each in the working direction of the vacuum cleaner nozzle 2 front transverse suction channel 8 or 9 or 10 is absorbent active. According to the particular nature of the floor surface to be sucked off, the corresponding suction channel 8 or 9 or 10 is activated. This optimum cleaning results are achieved even with different nature of the floor surfaces to be vacuumed without high shearing forces must be taken into account.

Bei dem Staubsaugermundstück 2 gemäß Fig. 4 sind auf dessen Rückseite an dem verlängerten Saugstutzen 5 noch Tragrollen 19 angeordnet. Diese Tragrollen 19 übernehmen einen wesentlichen Teil der über das Saugrohr 6 auf das Staubsaugermundstück 2 ausgeübten Andrückkraft. Dadurch wird der Kraftaufwand für das Hin- und Herbewegen des Staubsaugermundstückes 2 beim Saugen verringert.In the vacuum cleaner mouthpiece 2 shown in FIG. 4 5 support rollers 19 are arranged on the back of the extended suction nozzle. These support rollers 19 take over a substantial part of the force exerted on the suction pipe 6 on the vacuum cleaner nozzle 2 pressing force. As a result, the force required for reciprocating the vacuum cleaner mouthpiece 2 during suction is reduced.

Die Fig. 3 zeigt die drei Einstellmöglichkeiten des Staubsaugermundstückes 2. Dabei ist mit I die Arbeitsstellung für den ersten Saugkanal 8, mit II die Arbeitsstellung für den zweiten Saugkanal 9 und mit III die Arbeitsstellung für den dritten Saugkanal 10 bezeichnet. Beim Verschwenken von Mundstückteil 1 und Gehäuseoberteil 4 können diese beiden Teile durch eine Verrastung in der jeweiligen Stellung, in der einer der drei Saugkanäle 8 bzw. 9 bzw. 10 saugmäßig aktiviert ist, gehalten werden. Dadurch ist ein einwandfreies Arbeiten in den verschiedenen Stellungen des Staubsaugermundstückes 2 möglich.The working position for the first suction channel 8, with II the working position for the second suction channel 9 and III denotes the working position for the third suction channel 10. When pivoting mouthpiece part 1 and the upper housing part 4, these two parts can be held by a latching in the respective position in which one of the three suction channels 8 and 9 or 10 is activated suction. As a result, a perfect working in the different positions of the vacuum cleaner mouthpiece 2 is possible.

Bei der in Fig. 5 gezeigten Ausführungsvarianten ist in dem Gehäuseoberteil 4 des Staubsaugermundstückes 2 ein Walzenkörper 20 drehbar angeordnet. Der Walzenkörper 20 weist drei Saugkanäle 8-10 auf. Der Walzenkörper 20 ist vorteilhafterweise hohl ausgebildet und an seinem Umfang in den zwischen den Saugkanäle 8-10 liegenden Bereichen mit Durchtrittsöffnungen 21 versehen. Die Saugkanäle 8-10 sind strömungsmäßig mit dem Hohlraum 22 des Walzenkörpers 20 verbunden. Der Walzenkörper 20 ist in einen in dem Gehäuseoberteil vorgesehenen, hohlzylinderförmig ausgebildeten Aufnahmekanal 23 eingesetzt. An der Unterseite des Staubsaugermundstückes 2 weist der Aufnahmekanal 23 an seinem Umfang eine Unterbrechung auf, durch die der jeweils aktivierte Saugkanal 8 bzw. 9 bzw. 10 frei aus dem Aufnahmekanal 23 hervortritt und somit über eine zu reinigende Bodenfläche geführt werden kann. Im Bereich des Verbindungskanales 7 des Staubsaugermundstückes 2 ist der Aufnahmekanal 23 mit einer Verbindungsöffnung versehen, so daß über die entsprechende Durchtrittsöffnung 21 des Walzenkörpers 20 eine strömungmäßige Verbindung zwischen dem Verbindungskanal 7 und dem Hohlraum 22 des Walzenkörpers 20 und damit mit dem jeweils aktivierten Saugkanal 8 bzw. 9 bzw. 10 besteht. Die übrigen Saugkanäle und die entsprechenden Durchtrittsöffnungen 21 werden von der Wandung des Aufnahmekanales 23 abgedeckt und sind strömungsmäßig inaktiv.In the embodiment shown in Fig. 5, a roller body 20 is rotatably disposed in the upper housing part 4 of the vacuum cleaner nozzle 2. The roller body 20 has three suction channels 8-10. The roller body 20 is advantageously hollow and provided at its periphery in the lying between the suction channels 8-10 areas with passages 21. The suction channels 8-10 are fluidly connected to the cavity 22 of the roller body 20. The roller body 20 is inserted into a provided in the upper housing part, hollow cylindrical receiving channel 23. At the bottom of the vacuum cleaner mouthpiece 2, the receiving channel 23 at its periphery an interruption, through which the respective activated Suction channel 8 or 9 or 10 emerges freely from the receiving channel 23 and thus can be performed over a floor surface to be cleaned. In the region of the connecting channel 7 of the vacuum cleaner mouthpiece 2, the receiving channel 23 is provided with a connection opening, so that via the corresponding passage opening 21 of the roller body 20, a flow connection between the connecting channel 7 and the cavity 22 of the roller body 20 and thus with the respectively activated suction channel 8 and 9 or 10 exists. The remaining suction channels and the corresponding passage openings 21 are covered by the wall of the receiving channel 23 and are fluidly inactive.
