Breitere Saugdüsen werden lediglich für Industrieschmutzsauger eingesetzt. Die für den Industriebereich ausgelegten Saugdüsen weisen im Vergleich zu Bodendüsen für Haushalts-Staubsauger einen anderen Aufbau auf. Sie weisen einen in Saugrichtung schmales Gehäuseoberteil auf, in das ein den Saugmund formender Einsatz eingepasst ist. Der Saugkopf weist weder eine breite Gleitsohle noch einen im Gehäuseoberteil vertikal verstellbaren Träger mit zugeordnetem Umschalter auf. Der den Saugmund formende Einsatz ist austauschbar und wird bezüglich der konkreten Gestaltung für den Einsatzzweck, für den die Saugdüse vornehmlich bestimmt ist, angepasst.Wider suction nozzles are only used for industrial vacuum cleaners used. The designed for the industrial sector Suction nozzles have compared to floor nozzles for household vacuum cleaners another structure. They instruct you in Suction direction narrow housing upper part in which a Suction mouth-forming insert is fitted. The suction head has neither a wide sliding sole nor one in the upper part of the housing vertically adjustable carrier with assigned Switch to. The insert that forms the suction mouth is interchangeable and is regarding the concrete design for the purpose for which the suction nozzle is primarily intended adapted.

Aus WO 96/37 142 ist eine Bodendüse bekannt, deren Breite doppelt so groß ist wie die Breite einer Bodendüse für Haushalts-Staubsauger. Sie weist einen Saugmund auf, der mittig durch einen Steg unterteilt ist. In jeden Abschnitt des Saugmundes mündet ein Saugkanal ein. Die Bodendüse weist keinen vertikal verstellbaren Träger auf und ist nicht für den wechselweisen Betrieb auf Glattböden und textilen Bodenbelägen umschaltbar. Als Vorteil wird angegeben, dass die breite Saugdüse einen stabileren Bodenkontakt ergibt. Einen Beitrag zum energieeffizienten Saugen leistet die Druckschrift nicht.A floor nozzle whose width is known from WO 96/37 142 is twice the width of a floor nozzle for Household vacuum cleaner. It has a suction mouth that is divided in the middle by a web. In every section a suction channel opens into the suction mouth. The floor nozzle has no vertically adjustable support and is not for alternate operation on smooth floors and switchable textile floor coverings. As an advantage, that the wide suction nozzle has a more stable ground contact results. A contribution to energy-efficient vacuuming the publication does not perform.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Haushalts-Bodenstaubsauger ein möglichst energieeffizientes Saugen zu ermöglichen.The invention has for its object in a household vacuum cleaner the most energy efficient possible To allow suction.

Ausgehend von einem Haushalts-Bodenstaubsauger, dessen Saugkopf die eingangs beschriebenen Merkmale aufweist, wird die Aufgabe erfindungsgemäß dadurch gelöst, dass die Gleitsohle des Saugkopfes eine an den Enden des Saugmundes gemessene Arbeitsbreite von 350 bis 500 Millimetern aufweist. Im Vergleich zu den bekannten Ausführungen weist der erfindungsgemäße Saugkopf eine für Haushalts-Bodenstaubsauger besonders große Arbeitsbreite auf. Die erfindungsgemäße Ausbildung beruht auf der Überlegung, dass die Düsenbreite proportional in eine Leistungskennziffer eingeht, welche die Leistungsaufnahme des Bodenstaubsaugers auf die abgesaugte Fläche bezieht. Durch die unterseitige Gestaltung der Gleitsohle, insbesondere durch die Bemessung des Saugmundes, des Überstandes und der Breite der Saugmundkanten sowie des rückwärtig an den Saugmund anschließenden Abschnittes der Gleitsohle kann der Saugkopf so ausgelegt werden, dass die als Produkt aus Luftstrom und Unterdruck berechnete Saugleistung sich mit zunehmender Arbeitsbreite nicht oder nur wenig ändert. Insofern ist mit einer Staubsaugerdüse, die erfindungsgemäß eine Arbeitsbreite von 350 bis 500 Millimetern besitzen kann, ein energieeffizientes Saugen möglich. Mit zunehmender Arbeitsbreite wird bei der Bauform des Saugkopfes, die der erfindungsgemäßen Lehre zugrunde liegt, die bodenseitige Andruckkraft größer. Der Vergrößerung der Andruckkraft und der daraus resultierenden Schiebekraft zur Bewegung des Saugkopfes über die Bodenfläche kann durch Materialwahl der Gleitsohle und/oder durch eine frontseitige Abstützung an Gleitrollen entgegengewirkt werden.Starting from a household canister vacuum cleaner whose Suction head has the features described above the object is achieved in that the sliding sole of the suction head one measured at the ends of the suction mouth Working width of 350 to 500 millimeters. In comparison to the known designs, the inventive one Suction head one for household canister vacuum cleaners particularly large working width. The invention Training is based on the consideration that the nozzle width which is included proportionally in a performance indicator the power consumption of the vacuum cleaner on the extracted Area. Due to the underside design the sliding sole, especially by dimensioning the suction mouth, of the projection and the width of the suction mouth edges as well as the section adjoining the suction mouth at the rear The suction head can be designed in this way be that as a product of airflow and vacuum calculated suction power with increasing working width doesn't change or changes little. In this respect, with a vacuum cleaner nozzle, according to the invention a working width of 350 can have up to 500 millimeters, an energy efficient Sucking possible. With increasing working width at Design of the suction head, the teaching of the invention is based, the bottom pressure force is greater. The Increasing the pressure force and the resulting Pushing force for moving the suction head over the floor surface can be selected by the material of the sliding sole and / or counteracted by a front support on castors become.

Gemäß einer bevorzugten Ausführungsform der Erfindung besteht der Saugmund aus einem einzigen Kanal, der über seine Länge eine annähernd konstante Kanalbreite aufweist. Im Rahmen der Erfindung liegt es, die Gleitsohle aus Kunststoff zu fertigen. Bevorzugt ist jedoch eine Gleitsohle aus Metall. Zweckmäßig werden lange Fadenheberstreifen eingesetzt. Sie können gemäß einer bevorzugten Ausführung der Erfindung eine Länge aufweisen, die das 0,3- bis 0,5-fache der Arbeitsbreite der Gleitsohle beträgt.According to a preferred embodiment of the invention the suction mouth consists of a single channel that over its length has an approximately constant channel width.
