Der eingangs beschriebene Aufbau eines Saugkopfes für Haushalts-Bodenstaubsauger, der auch als Staubsaugerdüse bezeichnet wird, ist beispielsweise aus DE-A 196 28 070 bekannt und in der Praxis weit verbreitet. In der Praxis werden heute für den Hausgebrauch ausnahmslos Bodenstaubsauger eingesetzt, deren Saugköpfe eine Breite bis zu etwa 300 Millimeter aufweisen.The construction described above of a suction head for household vacuum cleaner, which is also referred to as a vacuum cleaner nozzle is, for example DE-A 196 28 070 known and widely used in practice. In practice, home vacuum cleaners are used without exception for home use, the suction heads have a width up to about 300 millimeters.

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. The designed for the industrial suction nozzles have a different structure compared to floor nozzles for household vacuum cleaners. They have a narrow in the suction direction of the upper housing part, in which a suction mouth forming insert is fitted. The suction head has neither a wide sliding sole nor a vertically adjustable in the upper housing part carrier with associated switch. The insert which forms the suction mouth is exchangeable and is adapted with regard to the specific design for the purpose for which the suction nozzle is primarily intended.

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.Out WO 96/37 142 is known a floor nozzle whose width is twice as large as the width of a floor nozzle for household vacuum cleaner. It has a suction mouth, the is divided in the middle by a bridge. In each section of the suction mouth opens a suction channel. The floor nozzle has no vertically adjustable support and is not switchable for alternating operation on smooth floors and textile floor coverings. As an advantage it is stated that the wide suction nozzle results in a more stable ground contact. A contribution to energy-efficient suction does not make the document.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Haushalts-Bodenstaubsauger ein möglichst energieeffizientes Saugen zu ermöglichen.The invention has for its object to allow a household vacuum cleaner as energy efficient as possible 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 vacuum cleaner whose suction head has the features described above, the object is achieved in that the sliding sole of the suction head has a measured at the ends of the suction mouth working width of 350 to 500 millimeters. In comparison to the known embodiments, the suction head according to the invention has a particularly large working width for household vacuum cleaner. The embodiment of the invention is based on the consideration that the nozzle width is proportional to a performance index, which refers to the power consumption of the vacuum cleaner on the suctioned surface. Due to the underside design of the soleplate, in particular by the design of the suction mouth, the supernatant and the width of the Saugmundkanten and the rear of the suction mouth adjacent portion of the sole plate, the suction head can be designed so that the calculated as a product of air flow and negative pressure suction with increasing working width not or only slightly changes. In this respect, an energy-efficient suction is possible with a vacuum cleaner nozzle, which according to the invention may have a working width of 350 to 500 millimeters. With increasing working width, the bottom-side pressure force is greater in the design of the suction head, which is the teaching of the invention is based. The increase in the pressure force and the resulting sliding force to move the suction head over the bottom surface can be counteracted by choice of material of the sliding sole and / or by a front support on rollers.

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.In the context of the invention is to manufacture the sliding sole made of plastic. However, a metal soleplate is preferred. Appropriately, long thread lifter strips are used. They may according to a preferred embodiment of the invention have a length which is 0.3 to 0.5 times the working width of the sliding sole.
