    Eine Staubsaugerdüse mit den eingangs beschriebenen drei Zweckbestimmungen ist aus DE 690 03 698 T2 bekannt. Als Element zur Reinigung von Glattböden sind ein Bürstenstreifen sowie eine Abziehlippe vorgesehen, die an einem als Tragplatte ausgebildeten Halter befestigt sind. Der Bürstenstreifen ist in der Draufsicht U-förmig ausgebildet und erstreckt sich in Richtung der Vorwärtsbewegung des Saugkopfes vor dem Saugmund sowie seitlich von diesem. Die flexible Abziehlippe ist hinter dem Saugmund angeordnet und nur bei einer Vorwärtsbewegung des Saugkopfes aktiv. Bei einer Rückwärtsbewegung wird die Nässe überfahren. Dies ist handhabungstechnisch von Nachteil, denn insbesondere im Haushalt ist es üblich, Böden mit hin- und hergehenden Bewegungen des Saugkopfes zu reinigen. Um Nässe von einem Fußboden in beiden Bewegungsrichtungen aufnehmen zu können, ist im Rahmen der bekannten Maßnahmen ein besonders gestalteter Wischer vorgesehen (Fig. 5 bis 7). Dieser besteht aus einer Leiste mit zwei parallelen Reihen aus versetzt angeordneten Lamellen. Die Anordnung ist relativ steif ausgebildet. Bei verschmutzen Böden ist dies von Nachteil. Ferner ist die Schiebekraft der Staubsaugerdüse groß.A vacuum cleaner nozzle with the three described above Purpose is known from DE 690 03 698 T2. As A brush strip is an element for cleaning smooth floors and a pull lip provided on a trained as a support plate holder are attached. The Brush strip is U-shaped in plan view and extends in the direction of the forward movement of the Suction head in front of the suction mouth and to the side of it. The flexible pull-off lip is arranged behind the suction mouth and only active when the suction head moves forward. at a backward movement will run over the wet. This is handling disadvantageous, especially in Household, it is common to have floors with back and forth Clean movements of the suction head. To get wet from one Being able to pick up flooring in both directions of movement is a special part of the known measures designed wiper provided (Fig. 5 to 7). This consists of a bar with two parallel rows staggered slats. The arrangement is relative stiff. In the case of dirty floors, this is of Disadvantage. Furthermore, the pushing force of the vacuum cleaner nozzle large.

    Aus US 3 107 387 ist eine Staubsaugerdüse bekannt, die ausschließlich zum Reinigen von nassen Glattböden geeignet ist. Der Saugkopf besteht aus einem unterseitig offenen, trichterförmigen Gehäuse, an dessen Unterkanten flexible Abziehlippen aus Gummi oder Kunststoff angeordnet sind. Zum Reinigen von trockenen Flächen, insbesondere für das Trockensaugen auf Teppichböden, ist die Staubsaugerdüse ungeeignet.From US 3 107 387 a vacuum cleaner nozzle is known which only suitable for cleaning wet smooth floors is. The suction head consists of an open bottom funnel-shaped housing, flexible on the lower edges Pull lips made of rubber or plastic are arranged. To the Cleaning dry surfaces, especially for that Dry vacuuming on carpets is the vacuum cleaner nozzle not suitable.

    Bei einer aus DE-A 38 01 757 bekannten Staubsaugerdüse, die für das Trockensaugen von Teppichböden optimiert ist, ist hinter dem Saugmund eine elastische Leiste bzw. Lippe angeordnet. Die Wirkung dieser Lippe besteht darin, den Saugstrom zu konzentrieren und das Entstehen unwirksamer Nebenluft zu verhindern. Für das Trockensaugen von Glattböden ist die bekannte Staubsaugerdüse nicht eingerichtet und für das Naßsaugen von Glattböden ist sie ungeeignet.In a vacuum cleaner nozzle known from DE-A 38 01 757, the is optimized for dry vacuuming carpets behind the suction mouth there is an elastic bar or lip arranged. The effect of this lip is that Concentrate suction flow and the ineffective emergence To prevent secondary air. For dry vacuuming smooth floors the well-known vacuum cleaner nozzle is not set up and it is unsuitable for wet vacuuming smooth floors.

    Der Erfindung liegt die Aufgabe zugrunde, eine Dreizweck-Staubsaugerdüse mit den eingangs beschriebenen Zweckbestimmungen anzugeben, die mit kleiner Schiebekraft bewegbar ist, gute Trockensaugeigenschaften auf Teppichböden besitzt und sowohl bei einer Vorwärtsbewegung als auch bei einer Rückwärtsbewegung Nässe sowie Schmutz von Glattböden wirksam aufnehmen kann.The invention has for its object a three-purpose vacuum cleaner nozzle with the purposes described at the beginning specify that movable with small pushing force has good dry suction properties on carpets and both forward and one Backward movement Effective wetness and dirt from smooth floors can record.

    Die Aufgabe wird bei einer Dreizweck-Staubsaugerdüse des eingangs beschriebenen Aufbaus erfindungsgemäß dadurch gelöst, daß die Abziehlippe in Richtung der Vorwärtsbewegung des Saugkopfes vor dem Saugmund angeordnet ist, daß neben der Abziehlippe Stützrollen angeordnet sind, die bei abgesenktem Halter auf dem Boden aufstehen und zusammen mit der Laufrolle den bodenseitigen Funktionsabstand der Abziehlippe beim Saugen von Glattböden bestimmen, und daß hinter dem Saugmund ein flexibler Abstreifer aus Gummi oder Kunststoff angeordnet ist. Die Stützrollen sowie die Laufrolle, welche zusammen Stützelemente bilden, sind so eingerichtet, daß sie beim Naßsaugen von Glattböden den Funktionsabstand der Abziehlippe bestimmen. Diese ist beim Naßsaugen auf dem zu reinigenden Glattboden abgestützt.The task is the triple-purpose vacuum cleaner nozzle construction described above according to the invention solved that the pull lip in the direction of the forward movement the suction head is arranged in front of the suction mouth that support rollers are arranged next to the pull-off lip, which at lowered holder stand up on the floor and together with the roller the bottom functional distance of the Determine the pull-off lip when vacuuming smooth floors, and that behind the suction mouth there is a flexible rubber wiper or Plastic is arranged. The support rollers as well as the Rollers, which together form support elements, are so set up that they the when vacuuming smooth floors Determine the functional distance of the pull lip. This is with Wet suction supported on the smooth floor to be cleaned.

    Gemäß einer ersten Ausführung der Erfindung sind die Stützrollen sowie die Laufrolle höhenfest an dem Saugkopf befestigt. Zusammen bestimmen sie beim Trockensaugen von Teppichböden den bodenseitigen Funktionsabstand der Saugmundkanten und der Fadenheber. Gemäß einer anderen Ausführung der Erfindung sind die Stützrollen an dem Halter gelagert und mit diesem zusammen ein- und ausfahrbar. Beim Trockensaugen von Teppichböden ist der Halter und mit diesem die Abziehlippe eingefahren, so daß die Saugkopfplatte auf dem zu reinigenden Teppichboden aufliegt und bei einer Bewegung des Saugkopfes auf diesem gleitet.According to a first embodiment of the invention Support rollers and the roller are height-fixed on the suction head attached. Together they determine when vacuuming dry Carpets the functional gap at the bottom of the suction mouth edges and the thread lifter. According to another version the invention are the support rollers on the holder stored and retractable and extendable together with it. At the Dry vacuuming of carpets is the holder and with this retracted the pull lip, so that the suction head plate lies on the carpet to be cleaned and at a movement of the suction head slides on this.

    Der hintere Abstreifer kann an der Unterseite des Saugkopfes gehäusefest angeordnet sein. Beim Trockensaugen von Teppichböden und Glattböden trägt er zu einer Konzentrierung des Saugluftstromes bei und verhindert den Eintritt unwirksamer Nebenluft. Beim Naßsaugen erfüllt er die Funktion eines Wischers, der bei einer Vorwärtsbewegung des Saugkopfes Nässe mitnimmt und dem Saugmundbereich zuführt, wo die Nässe abgesaugt wird. Der hinter dem Saugmund angeordnete flexible Abstreifer erfüllt insofern eine mehrfache Funktion. Gemäß einer anderen Ausführungsform der Erfindung ist der Halter als heb- und senkbare Tragplatte ausgebildet, an der auch der hintere Abstreifer angeschlossen ist. Er kann ähnlich der vorderen Abziehlippe gestaltet sein.The rear scraper can be on the underside of the suction head be arranged fixed to the housing. When vacuuming dry He helps carpets and smooth floors to concentrate of the suction air flow and prevents entry ineffective secondary air. When wet sucking, it fulfills the Function of a wiper, which when the Takes suction head with it and feeds it to the suction mouth area, where the moisture is sucked off. The one behind the suction mouth arranged flexible wipers thus fulfills one multiple function. According to another embodiment of the Invention is the holder as a lifting and lowering support plate trained to which the rear scraper is connected is. It can be similar to the front pull-off lip be designed.

    Die Erfindung geht von der Erkenntnis aus, daß die Bauteile üblicher, für das Trockensaugen von Teppichböden und Glattböden eingerichteter Staubsaugerdüsen ohne weiteres und ohne Erhöhung des fertigungstechnischen oder montagetechnischen Aufwandes zusätzlich auch zum Naßsaugen von Glattböden verwendbar sind, wenn die bei den bekannten Staubsaugerdüsen üblichen ein- und ausfahrbaren Bürstenleisten durch Abziehlippen aus Gummi oder Kunststoff ersetzt werden, die im ausgefahrenen Zustand beim Trockensaugen von Glattböden die Funktion einer Bürstenleiste erfüllen und entsprechend ausgelegt sind, und wenn weiterhin die Abstimmung der Stützelemente so eingerichtet ist, daß sie beim Trockensaugen von Teppichböden den Funktionsabstand der Saugmundkanten und der Fadenheber von dem Teppichboden bestimmen, und daß sie beim Naßsaugen von Glattböden den Funktionsabstand der Abziehlippen bestimmen.The invention is based on the knowledge that the components more common, for dry vacuuming carpets and Smooth floors of vacuum cleaner nozzles set up easily and without increasing the manufacturing or assembly technology Effort also for wet vacuuming Smooth floors can be used if the known Vacuum cleaner nozzles usual retractable and extendable brush strips with rubber or plastic pull-off lips to be replaced in the extended state when dry vacuuming smooth floors function as a brush strip meet and are designed accordingly, and if continue the coordination of the support elements is set up that the functional distance when vacuuming carpets dry the suction mouth edges and the thread lifter from that Determine carpeting, and that when wet vacuuming Smooth floors determine the functional distance between the pull-off lips.

    Im einzelnen bestehen im Rahmen der Erfindung mehrere Möglichkeiten der weiteren Ausbildung und Gestaltung der Dreizweck-Staubsaugerdüse. So läßt sich die Abstimmung so treffen, daß die Stützelemente alle angegebenen Funktionszwecke erfüllen, obgleich sie im Saugkopf fest angeordnet und nicht höhenverstellbar sind. Es besteht aber auch die Möglichkeit, die Stützelemente höhenverstellbar anzuordnen, wobei die Höhe gegenüber dem zu reinigenden Boden für die Zwecke Trockensaugen und Naßsaugen unterschiedlich gewählt werden können. Dazu können übliche Einstellvorrichtungen angeordnet sein, beispielsweise für die Fußbedienung oder auch für die Handbedienung. Damit die vor dem Saugmund angeordnete flexible Abziehlippe sowie der hinter dem Saugmund angeordnete flexible Abstreifer einerseits beim Naßsaugen ohne weiteres ihre Abziehfunktion erfüllen, andererseits beim Trockensaugen gleichsam wie Bürstenleisten funktionieren, lehrt die Erfindung, daß die in Vorwärtsbewegung des Staubsaugers vordere Abziehlippe bei der Vorwärtsbewegung flexibel umlenkbar ausgeführt oder angeordnet ist und für die Rückwärtsbewegung eine Versteifung erfährt. Der hinter dem Saugmund angeordnete Abstreifer stellt zweckmäßig eine gleichsam invers gestaltete Abziehlippe dar. Die Abziehlippe bzw. der Abstreifer können Profilierungen aufweisen, die in einer Richtung ihr Flächenträgheitsmoment reduzieren, so daß die beschriebene flexible Umlenkung erfolgt, und in der anderen Bewegungsrichtung das Flächenträgheitsmoment erhöhen, so daß die beschriebene Versteifung erfolgt. Man kann aber auch, gegebenenfalls zusätzlich zu den beschriebenen Maßnahmen, den Halter bzw. die Tragplatte mit Abstützausformungen versehen, die auf die Abziehlippe und/oder den Abstreifer in eine Bewegungsrichtung wie angegeben versteifend wirken. Sie erfüllen gerade bei dieser Ausführungsform beim Trockensaugen auch die Funktion einer klassischen Bürstenleiste.There are several in the scope of the invention Possibilities for further training and design of the Three-purpose vacuum cleaner nozzle. This is how the vote can be done meet that the support elements all specified functional purposes meet, although they are fixed in the suction head and are not adjustable in height. But there is also Possibility of arranging the support elements in a height-adjustable manner the height compared to the floor to be cleaned for the Purpose dry suction and wet suction selected differently can be. Common adjustment devices can be used for this be arranged, for example for foot control or also for manual operation. So that in front of the suction mouth arranged flexible pull-off lip and the one behind the Flexible scraper arranged on the one hand at Wet suction easily perform their peeling function, on the other hand, like dry brushes when vacuuming dry function, the invention teaches that the in Forward movement of the vacuum front puller lip the forward movement can be flexibly deflected or is arranged and a stiffener for the backward movement experiences. The scraper located behind the suction mouth expediently represents an inverse design Pull-off lip. The pull-off lip or the scraper can Have profiles that are in one direction Reduce the area moment of inertia so that the described flexible deflection takes place, and in the other direction of movement increase the area moment of inertia so that the stiffening described. But you can also if necessary in addition to the measures described, the holder or the support plate with support formations provided on the pull lip and / or the scraper stiffen in one direction of movement as indicated. They meet precisely in this embodiment Dry vacuuming also functions as a classic brush strip.

    Gemäß einer bevorzugten Ausführung der Erfindung weist die Abziehlippe eine vertikal gerippte Außenfläche sowie eine glatte, mit einer scharfen Unterkante abschließende Innenfläche auf. Die ausgefahrene Abziehlippe liegt bei der Vorwärtsbewegung des Saugkopfes mit den Außenrippen auf dem zu reinigenden Glattboden auf, wobei Schmutz sowie Nässe von dem zwischen den Außenrippen verbleibenden Hohlräumen überfahrbar sind. Bei einer Rückwärtsbewegung des Saugkopfes liegt die ausgefahrene Abziehlippe dagegen flächig auf dem zu reinigenden Glattboden auf und bildet eine scharfe, Schmutz und Nässe mitnehmende Wischkante. Der rückwärtige Abstreifer ist zweckmäßigerweise entsprechend gestaltet.According to a preferred embodiment of the invention, the Pull lip a vertically ribbed outer surface and a smooth with a sharp bottom edge Inner surface on. The extended pull-off lip lies with the Forward movement of the suction head with the outer ribs on the to be cleaned smooth floor, whereby dirt as well as wetness of the voids remaining between the outer ribs are run over. When the suction head moves backwards on the other hand, the extended pull-off lip is flat on the smooth floor to be cleaned and forms one sharp wiping edge that takes away dirt and moisture. The rear scraper is suitably appropriate designed.
