Die nachveröffentlichte Druckschrift
Der Erfindung liegt die Aufgabe zugrunde, die Handhabung sowie die Gebrauchseigenschaften der Bodendüse auf Glattböden zu verbessern.The invention has for its object to improve the handling and the performance characteristics of the floor nozzle on smooth floors.
Gegenstand der Erfindung und Lösung dieser Aufgabe ist eine Bodendüse für Staubsauger mit
einem Saugkopf, der eine unterseitige Gleitsohle mit einem quer zur Arbeitsrichtung sich erstreckenden Saugmund und einen in den Saugmund mündenden Saugkanal aufweist,
einem Saugrohranschlusselement, das um die horizontale Achse eines Kippgelenkes beweglich in den Saugkanal eingesetzt ist,
einer Laufrollenanordnungdie in einer am rückwärtigen Ende des Saugkanals vorgesehenen Vertiefung mittig unter dem Saugkanal angeordnet ist,
einem innerhalb des Saugkopfes angeordneten, vertikal verstellbaren Träger,
wobei an den Träger eine Dichtungsleiste angeschlossen ist, die in Saugrichtung vor der Gleitsohle angeordnet ist, wobei der Träger in Saugrichtung hinter der Gleitsohle eine auf Glattböden wirksame Arbeitsfläche aufweist, die zwischen der Gleitsohle und der Laufrollenanordnung verläuft und sich an beiden Seiten der Laufrollenanordnung nach hinten erstreckt, und wobei die vordere Dichtungsleiste und die hintere Arbeitsfläche mit einem Stellhub des Träger zusammen an der Unterseite des Saugkopfes so weit ausfahrbar sind, dass die Laufrollenanordnung bei einem Saugbetrieb auf Glattböden keinen Bodenkontakt hat und der Saugkopf auf der Arbeitsfläche des Trägers und der vorderen Dichtungsleiste abgestützt ist.The invention and solution to this problem is a floor nozzle for vacuum cleaners
a suction head which has a bottom-side sliding sole with a suction mouth extending transversely to the working direction and a suction channel opening into the suction mouth,
a Saugrohranschlusselement which is inserted around the horizontal axis of a tilting joint movable in the suction channel,
a roller arrangement which is arranged in a recess provided at the rear end of the suction channel, centrally under the suction channel,
a vertically arranged within the suction head, vertically adjustable support,
wherein the carrier is a sealing strip is connected, which is arranged in the suction direction in front of the sliding sole, wherein the carrier in the suction direction behind the sliding sole has an effective on smooth floors working surface which extends between the sliding sole and the roller assembly and on both sides of the roller assembly to the rear extends, and wherein the front sealing strip and the rear work surface with a stroke of the support together on the underside of the suction head are so far extendable that the roller assembly in a suction operation on smooth floors has no contact with the ground and the suction head on the working surface of the carrier and the front sealing strip is supported.
Der Träger ist mittels eines Schalters, z.B. eines an der Oberseite des Saugkopfes angeordneten Fußschalters, zwischen den Funktionsstellungen "Träger angehoben" und "Träger abgesenkt" verstellbar. In der Funktionsstellung "Träger angehoben" kann die Bodendüse zum Saugen von Teppichböden und Teppichen eingesetzt werden. Sie ist auf der Laufrollenanordnung abgestützt und der Saugkopf liegt schwenkbeweglich nur unter seinem Eigengewicht und unter der Wirkung des im Saugmund herrschenden Unterdrucks auf der Bodenfläche auf, so dass die Bodendüse mit geringer Schiebekraft über den Boden geführt werden kann. Zum Saugen von Glattböden, also Stein-, Parkett- oder Kunststoffböden, werden durch einen Stellhub des Trägers in die Funktionsstellung "Träger abgesenkt" die Arbeitsfläche des Trägers sowie die vordere Dichtungsleiste ausgefahren. In der Funktionsstellung "Träger abgesenkt" hat die Laufrollenanordnung keinen Bodenkontakt. Die Bodendüse ist in dieser Funktionsstellung an der Arbeitsfläche sowie der vorderen Dichtungsleiste abgestützt. Diese Elemente gleiten auf der Bodenfläche, so dass Längs- und Querbewegungen sowie insbesondere auch Bewegungen, die bei der Handhabung eines Wischmops üblich sind, möglich sind. Durch die erfindungsgemäße Ausbildung der Arbeitsfläche ergibt sich eine für die Reinigung von Glattböden günstige Krafteinleitung. Die bei Saugbewegungen über das Saugrohr ausgeübten Kräfte werden im Wesentlichen von der Arbeitsfläche aufgenommen, wodurch eine gute mechanische Wirkung der Arbeitsfläche auf dem Bodenbelag erzielt wird. Daneben dichtet die unterseitig vorstehende Arbeitsfläche ebenso wie vordere Dichtungsleiste den unterhalb der Gleitsohle liegenden Saugbereich ab, so dass sich ein saugwirksamer Unterdruck einstellen kann.The carrier is adjustable by means of a switch, for example a foot switch arranged at the top of the suction head, between the functional positions "carrier raised" and "carrier lowered". In the functional position "carrier raised", the floor nozzle can be used for vacuuming carpets and carpets. It is supported on the roller assembly and the suction head is pivotally only under its own weight and under the effect of prevailing in the suction vacuum on the bottom surface, so that the floor nozzle with low pushing force can be performed over the ground. For sucking smooth floors, so stone, parquet or plastic floors, the work surface of the carrier and the front sealing strip are extended by a stroke of the carrier in the functional position "carrier lowered". In the functional position "carrier lowered", the roller arrangement has no Ground contact. The floor nozzle is supported in this functional position on the work surface and the front sealing strip. These elements slide on the bottom surface, so that longitudinal and transverse movements and in particular movements that are common in the handling of a mop, are possible. The inventive design of the work surface results in a favorable for the cleaning of smooth floors force application. The forces exerted on the suction tube during suction movements are essentially absorbed by the working surface, whereby a good mechanical effect of the working surface on the floor covering is achieved. In addition, the underside projecting working surface seals as well as the front sealing strip lying below the sliding sole suction, so that an absorbent negative pressure can be adjusted.
Die vordere Dichtungsleiste ist zweckmäßig als Borstenleiste ausgebildet. Andere Ausführungen, z.B. Leisten aus Gummi oder Schaumstoff, sollen nicht ausgeschlossen sein.The front sealing strip is expediently designed as a bristle strip. Other designs, e.g. Moldings made of rubber or foam, should not be excluded.
Für die Ausgestaltung der auf einem Glattboden wirksamen Arbeitsfläche bestehen zahlreiche Möglichkeiten, deren Auswahl sich nach dem Anwendungsfall richtet, für den die Bodendüse bevorzugt ausgelegt wird. Eine Ausführungsform sieht vor, dass die Arbeitsfläche des Trägers mit Borstenbüscheln besetzt ist. Die Borstenbüschel sind vorzugsweise ein- oder mehrreihig am Umfang des Trägers angeordnet. Eine Ausstattung mit harten Borsten erweitert die Anwendung der Bodendüse für Räume mit höherem Verschmutzungsgrad, z.B. Kellerräume oder Garagen. Die Arbeitsfläche des Trägers kann ferner einen weichen, zum Polieren von glatten Bodenbelägen geeigneten Belag aufweisen, z.B. für Haushalte mit überwiegendem Glattbodenanteil. Gemäß einer weiteren Ausführungsform ist die Arbeitsfläche mit einem abnehmbaren Tuch bestückt. Bei dem Tuch kann es sich um ein trockenes oder feuchtes Bodentuch handeln. Das Tuch kann als Einwegtuch oder waschbares Tuch ausgebildet sein. Ferner liegt es im Rahmen der Erfindung, Trockentücher mit einem guten Staubaufnahmevermögen, z.B. aus einem Mikrofasergewebe, einzusetzen.For the design of effective on a smooth floor working surface there are numerous possibilities, the selection of which depends on the application, for which the floor nozzle is preferably designed. One embodiment provides that the working surface of the carrier is occupied by bristle tufts. The bristle tufts are preferably arranged in one or more rows on the circumference of the carrier. An equipment with hard bristles extends the application of the floor nozzle for rooms with a higher degree of contamination, such as basements or garages. The work surface of the wearer may further comprise a soft covering suitable for polishing smooth floor coverings, eg for households with a predominantly smooth floor portion. According to another embodiment, the work surface is equipped with a removable cloth. The cloth may be a dry or damp floor cloth. The cloth may be formed as a disposable cloth or washable cloth. Furthermore, it lies within the framework of Invention, dry wipes with a good dust-holding capacity, eg from a microfibre fabric to use.
