Description

Die Erfindung betrifft einen Saugkopf für Bodenstaubsauger, insbesondere Haushaltsstaubsauger, mit einem Gehäuse und einer an der Unterseite des Gehäuses angeordneten Gleitsohle, wobei die Gleitsohle einen quer zur Arbeitsrichtung sich erstreckenden Saugkanal mit einem von einer in Arbeitsrichtung vorderen und hinteren Saugmundkante begrenzten Saugmund aufweist. Die Saugmundkanten sind mit Fadenhebern ausgerüstet. Die hintere Saugmundkante kann zu der vorderen Saugmundkante parallel oder zumindest abschnittsweise auch V-förmig zu dieser ausgerichtet sein. Die Gleitsohle ist an der Unterseite des Gehäuses fest oder kippbeweglich angeordnet.The invention relates to a suction head for vacuum cleaners, especially household vacuum cleaners, with a housing and a sliding sole arranged on the underside of the housing, where the sliding sole is transverse to the working direction extending suction channel with one of one in Working direction front and rear suction mouth edge has limited suction mouth. The suction mouth edges are with Thread lifters equipped. The rear edge of the suction mouth can be too the front suction mouth edge parallel or at least in sections also be V-shaped to this. The sliding sole is fixed to the bottom of the case or arranged tiltable.

Die Saugmundkanten grenzen den Saugkanal gegenüber dem Bodenbelag hin ab, so daß in einem entstehenden engen Spalt zwischen Saugmundkante und Bodenbelag eine Luftströmung mit hoher Geschwindigkeit entsteht, die für die Saugwirkung maßgebend ist und das Säubern des Bodenbelages bewirkt. Bei marktgängigen Saugköpfen für Haushaltsstaubsauger beträgt der mittlere Abstand zwischen den Saugmundkanten etwa 9 bis 25 mm. Der Abstand zwischen den Saugmundkanten ist wesentlich für die Gebrauchseigenschaften des Saugkopfes.The suction mouth edges limit the suction channel compared to that Floor covering down, so that in an emerging narrow gap an air flow between the edge of the suction mouth and the floor covering high speed arises for the suction is decisive and causes cleaning of the floor covering. At commercially available suction heads for household vacuum cleaners the average distance between the suction mouth edges is about 9 to 25 mm. The distance between the suction mouth edges is essential for the performance characteristics of the suction head.

Im Rahmen der bekannten Maßnahmen ist der Abstand der Saugmundkanten ein unveränderliches Konstruktionsmerkmal des Saugkopfes. Die Bemessung richtet sich nach dem Bodenbelag, für den der Saugkopf primär ausgelegt wird. As part of the known measures, the distance is the Suction mouth edges an unchangeable design feature of the suction head. The dimensioning is based on the Floor covering for which the suction head is primarily designed.

Der Erfindung liegt die Aufgabe zugrunde, einen Saugkopf für Bodenstaubsauger anzugeben, dessen Saugeigenschaften an den Bodenbelag angepaßt werden können.The invention has for its object a suction head for vacuum cleaners to specify the suction properties the flooring can be adjusted.

Zur Lösung dieser Aufgabe lehrt die Erfindung, daß der Abstand zwischen den Saugmundkanten einstellbar und betriebsmäßig veränderbar ist. Eine Anpassung der Saugmundbreite und damit eine Anpassung der Saugeigenschaften an den Bodenbelag ist möglich. Die weitere Ausgestaltung kann so getroffen werden, daß der Abstand der Saugmundkanten von dem Anwender mechanisch eingestellt wird oder sich nach Maßgabe einer Führungsgröße, z.B. des im Saugkanal herrschenden Unterdruckes oder der auf den Saugkopf wirkenden Schiebekraft, selbsttätig einstellt.To achieve this object, the invention teaches that Distance between the suction mouth edges adjustable and is operationally changeable. An adjustment of the suction mouth width and thus an adaptation of the suction properties the flooring is possible. The further configuration can so that the distance between the suction mouth edges of is mechanically adjusted to the user or after Providing a guide variable, e.g. the prevailing in the suction channel Negative pressure or that acting on the suction head Pushing force, automatically adjusts.

Gemäß einer ersten Ausführungsform der Erfindung ist die hintere Saugmundkante an einem beweglichen Träger angeordnet und ist an den Träger eine Stelleinrichtung mit einem Fuß- oder Handhebel angeschlossen. Vorzugsweise erfolgt die Einstellung zwischen zwei vorgegebenen Endwerten. Gemäß einer anderen bevorzugten Ausführung der Erfindung ist die hintere Saugmundkante an einem beweglichen Träger angeordnet, der bei einer Vorwärtsbewegung des Saugkopfes in einem von Anschlägen begrenzten Arbeitsbereich gegen eine Federanordnung mit mindestens einer Druckfeder bewegbar ist, wobei der Saugmund sich nach Maßgabe des auf die hintere Saugmundkante wirkenden Bewegungswiderstandes innerhalb des durch die Anschläge begrenzten Arbeitsbereiches weiter öffnet und schließt. Die Federanordnung ist so dimensioniert, daß der Saugmund in Ruhestellung sowie bei einer Bewegung des Saugkopfes über Glattböden und Teppichböden mit geringem Bewegungswiderstand, z.B. Schlingenware, weitgehend geschlossen ist. Solche Böden werden folglich mit einem für diese Böden vorteilhaften schmalen Saugmund abgesaugt. Bei Teppichböden mit hohem Bewegungswiderstand, z.B. hochfloriger Teppichböden, öffnet sich der Saugmund, wenn der Saugkopf in Arbeitsrichtung über diese Böden bewegt wird. Der sich dann einstellende breite Saugmund erlaubt ein effektives Absaugen der hochflorigen Velourböden. Bei Auslegung der Federanordnung mit einer progressiven oder stufenförmigen Federkennlinie lassen sich beliebige Zwischenstellungen erzeugen. In weiterer Ausgestaltung lehrt die Erfindung, daß die vordere Saugmundkante ebenfalls an einem beweglichen Träger angeordnet ist, der bei einer Rückwärtsbewegung des Saugkopfes in einem von Anschlägen begrenzten Arbeitsbereich gegen eine Federanordnung mit mindestens einer Druckfeder bewegbar ist, wobei der Saugmund sich nach Maßgabe des auf die vordere Saugmundkante wirkenden Bewegungswiderstandes innerhalb des durch die Anschläge begrenzten Arbeitsbereiches weiter öffnet und schließt. Bei dieser Ausführung ist gewährleistet, daß sich auch bei einer Rückwärtsbewegung des Saugkopfes der Saugmund nach Maßgabe des zu reinigenden Bodenbelages öffnet und schließt. Sind vordere und hintere Saugmundkante entsprechend beweglich eingerichtet, ist es möglich, den Bodenbelag in hin- und hergehenden Schiebebewegungen bei sich jeweils optimal einstellender Saugmundbreite abzureinigen.According to a first embodiment of the invention rear suction mouth edge arranged on a movable support and is an actuator with a carrier Foot or hand lever connected. This is preferably done Setting between two specified end values. According to Another preferred embodiment of the invention is rear suction mouth edge arranged on a movable support, the one with a forward movement of the suction head work area limited by attacks against a Spring arrangement movable with at least one compression spring is, the suction mouth according to the on the rear suction mouth edge effective movement resistance within the working area limited by the stops opens and closes further. The spring arrangement is dimensioned so that the suction mouth is at rest as well as when the suction head moves over smooth floors and Carpets with little movement resistance, e.g. Looped, largely closed. Such floors are therefore advantageous for these soils narrow suction mouth. For carpets with high Resistance to movement, e.g. deep-pile carpets, opens the suction mouth when the suction head is facing is moved over these floors. The one that then arises wide suction mouth allows effective suction of the deep-pile Velor floors. When designing the spring arrangement with a progressive or step-shaped spring characteristic any intermediate positions can be created. In Another embodiment teaches the invention that the front Suction mouth edge also on a movable support is arranged, when the suction head moves backward in a work area limited by attacks against a spring arrangement with at least one compression spring is movable, with the suction mouth in accordance with the the front suction mouth edge acting movement resistance within the working area limited by the stops opens and closes further.
