    Eine Bodendüse des beschriebenen Aufbaus ist aus DE-U 298 12 377 bekannt. Bei der bekannten Ausführung ist der Saugkopf mittels eines Kippgelenkes an den Luftführungskanal angeschlossen. Der Saugkopf enthält einen vertikal beweglichen und durch einen Fußschalter betätigbaren Borstenträger mit Borstenleisten, die durch bodenseitige Öffnungen in einer Bodenplatte des Saugkopfes ein- und ausfahrbar sind. Beim Saugen von Teppichbelägen gleitet die Bodenplatte auf dem zu reinigenden Boden. Zum Reinigen von glatten Bodenbelägen werden die Borstenleisten durch Betätigung des Fußschalters ausgefahren. Der kippbeweglich an den Luftführungskanal angeschlossene Saugkopf passt sich an Bodenunebenheiten an und ist unabhängig von der Ausrichtung des an das Wickelrohr angeschlossenen Saugrohres stets planparallel zu dem zu reinigenden Boden ausgerichtet.A floor nozzle of the construction described is out DE-U 298 12 377 known. In the known version the suction head by means of a tilt joint on the air duct connected. The suction head contains one vertically movable and operated by a foot switch Bristle holder with bristle strips that pass through bottom openings in a base plate of the suction head are retractable and extendable. When vacuuming carpets the base plate slides on the floor to be cleaned. To the The bristle strips are used to clean smooth floor coverings extended by operating the foot switch. The tiltable connected to the air duct Suction head adapts to uneven floors and is regardless of the orientation of the on the winding tube connected suction pipe always parallel to the aligned cleaning floor.

    Aus DE-A 42 43 244 ist eine Bodendüse bekannt, die ohne Umschaltmechanismus allbodentauglich sowohl zum Saugen von Teppichbelägen als auch zum Saugen von glatten Böden einsetzbar ist. Der Saugkopf ist auf Rollen geführt und weist ein kippbewegliches Saugmundstück auf, das sich planparallel zu dem zu reinigenden Bodenbelag ausrichtet. Das Saugmundstück besteht aus einer schmalen Bodenplatte mit wannenartig eingeformtem Kanal und ist schwenkbeweglich im Saugkopf gelagert. In Saugrichtung hinter dem Saugmundstück ist eine stets am Boden anliegende Bodendichtleiste angeordnet.From DE-A 42 43 244 a floor nozzle is known which without Switching mechanism suitable for all floors for both vacuuming Carpet coverings as well as for vacuuming smooth floors can be used. The suction head is guided on rollers and has a tilting suction mouthpiece that is aligned parallel to the floor covering to be cleaned. The suction mouthpiece consists of a narrow base plate with trough-shaped channel and can be swiveled stored in the suction head. In the suction direction behind the suction nozzle is a floor sealing strip that always lies against the floor arranged.

    Bei den beschriebnen Ausführungen passt sich der Saugmund an Bodenunebenheiten an und ist unabhängig von der Haltung und Ausrichtung des an das Wickelrohr angeschlossenen Saugrohres parallel zum Boden ausgerichtet. Das ermöglicht grundsätzlich ein effektives Reinigen der Bodenfläche. Andererseits besteht insbesondere bei hochflorigen Teppichbelägen die Gefahr, dass der Saugmund sich am Boden festsaugt und die Schiebekraft, die bei den Saugbewegungen aufgebracht werden muss, stark ansteigt. In extremen Fällen führt das Festsaugen der Bodendüse zu unangenehmen Hoppeleffekten, bei deren Auftreten ein wirksames Reinigen nicht mehr möglich ist. The suction mouth fits in the described versions unevenness and is independent of posture and alignment of the connected to the winding tube Suction pipe aligned parallel to the floor. This allows basically an effective cleaning of the floor surface. On the other hand, there is particularly in the case of deep-pile carpets the danger that the suction mouth is on the floor stuck and the pushing force that occurs during the suction movements must be applied, increases sharply. In extreme cases the suction of the floor nozzle leads to unpleasant hopping effects, when they occur, effective cleaning is not is more possible.

    Eine Bodendüse mit ausgewogenen Gebrauchseigenschaften muss zahlreiche, unterschiedliche Anforderungen erfüllen. Der Saugkopf soll (quer zur Saugrichtung) eine ausreichende Länge besitzen, damit eine große Bodenfläche mit möglichst wenig Arbeitsbewegungen gereinigt werden kann. Der Saugmund muss ferner so gestaltet sein, dass Fasern und Kleinteile, z.B. Büroklammern, Papierschnitzel und dergleichen aufgenommen werden. Insofern ist zumindest bereichsweise eine breite Ansaugöffnung zweckmäßig. Die Bodendüse muss ferner ein gutes Staubaufnahmevermögen besitzen, das von der Mitte zu den äußeren Rändern des Saugkopfes nicht schlechter werden darf. Durch die Gestaltung und Bemessung des Saugmundes muss sichergestellt sein, dass sich im gesamten Saugmund eine möglichst gleichmäßige Druckverteilung einstellt. Schließlich muss die Bodendüse so ausgebildet werden, dass sie beim Saugen mit geringer Schiebekraft bewegt werden kann und auch bei hochflorigen Teppichbelägen ein Festsaugen, bei dem ein ordnungsgemäßer Betrieb nicht mehr möglich ist, ausgeschlossen ist.A floor nozzle with balanced usage properties must meet numerous, different requirements. The Suction head should be sufficient (across the direction of suction) Have length so that a large floor area with as much as possible little work movements can be cleaned. The suction mouth must also be designed so that fibers and small parts, e.g. Paper clips, shredded paper and the like are added become. In this respect, at least in some areas wide suction opening is useful. The floor nozzle must also have a good dust absorption capacity, that from the center to the outer edges of the suction head not worse may be. By designing and dimensioning the Suction mouth must be ensured that the whole Suction mouth as even a pressure distribution as possible sets. Finally, the floor nozzle must be designed in this way be that when vacuuming with low pushing force can be moved and also with deep-pile carpets a sucking down where proper operation is not is more possible is excluded.

    In der Praxis eingeführte Bodendüsen des eingangs beschriebenen Aufbaus weisen einen in Saugrichtung gesehen verhältnismäßig breiten Saugmund auf, um nach herrschender Lehre eine gute Faser- und Staubaufnahme, insbesondere auch eine gleichmäßige Druckverteilung im Saugmund, zu gewährleisten. Der Saugmund besteht bei einigen Ausführungen aus einem geraden, bodenseitig offenen Kanal mit parallel zueinander angeordneten Saugkanten, deren Abstand im Mittel etwa 20 mm beträgt. Bei anderen Ausführungen nimmt die Breite des Saugmundes von der Saugkopfmitte nach außen hin ab, und zwar von etwa 25 mm auf etwa 10 mm.In practice introduced floor nozzles of the entrance described construction have seen in the suction direction relatively wide suction mouth to look after prevailing Teach good fiber and dust absorption, especially an even pressure distribution in the suction mouth, too guarantee. The suction mouth exists in some versions from a straight channel open at the bottom suction edges arranged parallel to each other, their distance is about 20 mm on average. In other versions increases the width of the suction mouth from the center of the suction head from the outside, from about 25 mm to about 10 mm.

    Gemäß DE-C 199 00 968 ist es für die Faser- und Staubaufnahme vorteilhaft, wenn der Saugmund im Bereich seines Mittelabschnittes breiter ausgebildet ist und eine Vertiefung aufweist, welche die in Saugrichtung hinteren Saugmundkanten im Bereich einer Ansaugöffnung unterbricht und rückseitig von einem Steg begrenzt ist, an den eine mit dem hinteren Fadenheber bestückte Aufnahmetasche anschließt. Der bodenseitige Einströmquerschnitt des Saugmundes nimmt bei dieser Ausgestaltung beachtlich zu.According to DE-C 199 00 968 it is for fiber and dust absorption advantageous if the suction mouth in the area of his Middle section is wider and a Has depression which the rear in the suction direction Suction mouth edges in the area of a suction opening interrupts and is bounded on the back by a web to which one is connected holding pocket on the rear thread lifter connects. The inflow cross-section of the suction mouth at the bottom increases considerably with this configuration.

    Die bekannten Bodendüsen sind im Hinblick auf die Faser- und Staubaufnahme weitgehend optimiert. Dennoch sind die Saugeigenschaften nicht immer ausgewogen, da die Maßnahmen zur Verbesserung der Staub- und Faseraufnahme durch eine größere Schiebekraft erkauft werden.The known floor nozzles are and dust absorption largely optimized. Still they are Suction properties are not always balanced as the measures to improve the dust and fiber absorption by a greater pushing force can be bought.

    Der Erfindung liegt die Aufgabe zugrunde, eine Bodendüse des eingangs beschriebenen Aufbaus so weiter auszubilden, dass sie bei unverändert guter Faser- und Staubaufnahme auch auf textilen Bodenbelägen leichtgängig bewegt werden kann und sich selbst bei hochflorigen Teppichböden nicht festsaugen kann.The invention has for its object a floor nozzle to further develop the structure described at the beginning, that with unchanged good fiber and dust absorption can also be moved easily on textile floor coverings can and not even with deep-pile carpets can suck up.

    Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass der bodenseitige Einströmquerschnitt des einen Umfang von mehr als 530 mm aufweisenden Saugmundes kleiner ist als 5000 mm2. Bei Einhaltung des erfindungsgemäßen Grenzwertes ist es ausgeschlossen, dass die an einen handelsüblichen Bodenstaubsauger angeschlossene Bodendüse sich auf textilen Bodenbelägen festsaugt. Die Bodendüse ist mit kleiner Schiebekraft bewegbar. Der Saugmund kann weitgehend beliebig gestaltet werden, wobei stets der erfindungsgemäße Grenzwert für den Einströmquerschnitt eingehalten werden muss.The object is achieved according to the invention in that the inflow cross section at the bottom of the suction mouth having a circumference of more than 530 mm is smaller than 5000 mm 2 . If the limit value according to the invention is adhered to, it is impossible for the floor nozzle connected to a commercially available floor vacuum cleaner to get stuck on textile floor coverings. The floor nozzle can be moved with little pushing force. The suction mouth can largely be designed as desired, the limit value for the inflow cross section according to the invention always having to be observed.

    Der Saugmund weist einen von den Fadenhebern begrenzten Mittelabschnitt mit einer an den Luftführungskanal anschließenden Ansaugöffnung und beidseits des Mittelabschnittes jeweils einen von den Saugmundkanten begrenzten schmalen Saugkanal auf. Im Rahmen der Erfindung liegt es, den Saugmund im Bereich des Mittelabschnittes wesentlich breiter auszubilden als in den beiderseits anschließenden Abschnitten. Überraschend wird die Staubaufnahme nicht nachteilig beeinflusst, wenn die an den Mittelabschnitt angrenzenden Zweige des Saugmundes sehr schmal, also mit einem sehr kleinen Abstand zwischen den Saugmundkanten, ausgebildet sind. Auch für die Länge des Saugkopfes (quer zur Saugrichtung) ergeben sich keine Einschränkungen. Zur Einhaltung des vorgegebenen Einströmquerschnittes ist der Saugmund entsprechend schmaler auszubilden, wenn der Saugkopf eine große Länge besitzt.The suction mouth has one limited by the thread lifters Middle section with one on the air duct subsequent suction opening and on both sides of the middle section one each delimited by the suction mouth edges narrow suction channel. It is within the scope of the invention the suction mouth in the area of the middle section essential to train more broadly than in those that follow on both sides Sections. The dust pickup is not surprising adversely affected when attached to the midsection adjacent branches of the suction mouth very narrow, i.e. with a very small distance between the suction mouth edges, are trained. Also for the length of the suction head (across to suction direction) there are no restrictions. For Compliance with the specified inflow cross section is the Make the suction mouth correspondingly narrower if the Suction head has a long length.

    Gemäß einer bevorzugten Ausführung der Erfindung sind die in Saugrichtung vorderen und hinteren Saugmundkanten parallel angeordnet, wobei der Abstand zwischen den Saugmundkanten weniger als 16 mm, vorzugsweise weniger als 14 mm, beträgt. Bei sehr kleinen Abständen zwischen den Saugmundkanten kann es vorteilhaft sein, wenn die beiderseits des Mittelabschnittes anschließenden Saugkanäle des Saugmundes oberhalb der Saugmundkanten eine die Druckverteilung im Saugmund fördernde Querschnittserweiterung aufweisen. Die in den Saugmund einströmende Luft kann innerhalb des Saugmundes mit geringem Strömungsdruckverlust in den entsprechend breiten Saugkanälen abgeleitet werden.According to a preferred embodiment of the invention, the front and rear suction mouth edges in the direction of suction arranged in parallel, the distance between the Suction mouth edges less than 16 mm, preferably less than 14 mm. With very small distances between the Suction lip edges can be advantageous if the Suction channels adjoining both sides of the central section of the suction mouth above the edges of the suction mouth Pressure distribution in the suction mouth enhances cross-sectional expansion exhibit. The air flowing into the suction mouth can within the suction mouth with little flow pressure loss derived in the correspondingly wide suction channels become.

    Gemäß einer bevorzugten Ausführung der Erfindung ist der Saugmund im Bereich seines Mittelabschnittes breiter ausgebildet und weist eine Vertiefung auf, welche die in Saugrichtung hinteren Saugmundkanten im Bereich der Ansaugöffnung unterbricht und rückseitig von einem Steg begrenzt ist, an den eine mit dem hinteren Fadenheber bestückte Aufnahmetasche anschließt. Die sich beidseits an den Mittelabschnitt anschließenden Abschnitte des Saugmundes sind entsprechend schmal ausgebildet, um den erfindungsgemäßen Grenzwert für den Einströmquerschnitt einzuhalten.According to a preferred embodiment of the invention, the Suction mouth wider in the area of its central section and has a recess which the in Suction direction rear suction mouth edges in the area of Intake opening interrupts and on the back by a web is limited to the one with the rear thread lifter equipped receiving pocket connects. The two sides the middle section adjoining sections of the suction mouth are accordingly narrow to the limit value according to the invention for the inflow cross section to adhere to.

Im Bereich seines Mittelabschnittes 9 ist der Saugmund 7 breiter ausgebildet und weist z.B. eine Vertiefung 12 auf, welche die in Saugrichtung hinteren Saugmundkanten im Bereich der Ansaugöffnung unterbricht und rückseitig von einem Steg 13 begrenzt ist, an den eine mit dem hinteren Fadenheber 5 bestückte Aufnahmetasche anschließt. 2 that the suction mouth 7 one of the Thread lifters 5 limited middle section 9 with a Air duct connecting intake 10 and on either side of the middle section 9 one of each Has suction mouth edges 6 limited narrow suction channel 11. The suction mouth 7 is in the area of its middle section 9 broader and e.g. a recess 12, which the suction mouth edges at the rear in the suction direction Area of the intake opening interrupts and on the back of a web 13 is limited to which one with the rear Thread lifter 5 equipped receiving pocket connects.

    Erfindungsgemäß ist der bodenseitige Einströmquerschnitt des einen Umfang von mehr als 530 mm aufweisenden Saugmundes 7 kleiner als 5000 mm2 und vorzugsweise kleiner als 4500 mm2. Die beiderseits des Mittelabschnittes 9 anschließenden kanalförmigen Abschnitte 11 des Saugmundes 7, im folgenden auch als Saugkanäle 11 bezeichnet, sind sehr schmal ausgebildet, damit der Vorgabewert für den Einströmquerschnitt eingehalten wird. Im Ausführungsbeispiel sind die in Saugrichtung vorderen und hinteren Saugmundkanten 6 parallel angeordnet, wobei der Abstand zwischen den Saugmundkanten weniger als 16 mm beträgt. Der kanalförmige Abschnitt 11 des Saugmundes 7 kann, wie in Fig. 3 dargestellt, einen im wesentlichen rechteckförmigen Querschnitt aufweisen.According to the invention, the inflow cross section at the bottom of the suction mouth 7, which has a circumference of more than 530 mm, is less than 5000 mm 2 and preferably less than 4500 mm 2 . The channel-shaped sections 11 of the suction mouth 7 adjoining the central section 9 on both sides, also referred to below as suction channels 11, are very narrow so that the specified value for the inflow cross section is maintained. In the exemplary embodiment, the front and rear suction mouth edges 6 in the suction direction are arranged in parallel, the distance between the suction mouth edges being less than 16 mm. The channel-shaped section 11 of the suction mouth 7 can, as shown in FIG. 3, have an essentially rectangular cross section.

    Angestrebt wird eine gleichmäßige Druckverteilung im Saugkanal. Bei der in Fig. 4 dargestellten Ausführung weisen die beiderseits des Mittelabschnittes anschließenden Saugkanäle 11 des Saugmundes 7 oberhalb der Saugmundkanten 6 eine die Druckverteilung im Saugmund fördernde Querschnittserweiterung auf. Der Abstand zwischen den Saugmundkanten 6 ist kleiner als die oberhalb der Saugmundkanten gemessene Breite des die einströmende Luft abführenden Kanals. Die Ausgestaltung ermöglicht eine sehr gleichmäßige Druckverteilung entlang den Saugmundkanten 6. Gleichzeitig gelingt es, die Fläche des Einströmquerschnittes klein zu halten, was sich günstig auf die Schiebekraft des Saugkopfes auswirkt. The aim is an even pressure distribution in the Suction channel. In the embodiment shown in Fig. 4 have the adjoining on both sides of the central section Suction channels 11 of the suction mouth 7 above the suction mouth edges 6 a cross-sectional expansion which promotes the pressure distribution in the suction mouth on. The distance between the Saugmundkanten 6 is smaller than that above the Suction mouth edges measured width of the incoming air laxative channel. The design enables a very even pressure distribution along the suction mouth edges 6. At the same time, the area of the inflow cross-section succeeds to keep small what is favorable to the Pushing force of the suction head affects.

    Die in dem Ausführungsbeispiel dargestellten Bodendüsen eignen sich zum Anschluss an handelsübliche Bodenstaubsauger, die eine effektive Luftleistung von etwa 500 Watt aufweisen. Die effektive Luftleistung L ( Watt) ist definiert als L = Δp x V.

    Δp:
    Druckdifferenz zum Atmosphärendruck (N/m2)
    V.:
    Luftstrom
    The floor nozzles shown in the exemplary embodiment are suitable for connection to commercially available cylinder vacuum cleaners which have an effective air output of approximately 500 watts. The effective air power L (watt) is defined as L = Δ p x V.
    Δ p :
    Pressure difference to atmospheric pressure (N / m 2 )
    V .:
    Airflow

    Druckdifferenz und Luftstrom sind jeweils in der Bodendüse gemessen.Pressure difference and air flow are in the floor nozzle measured.

    Werden Bodenstaubsauger mit noch höherer effektiver Luftleistung eingesetzt, sollte der Einströmquerschnitt des Saugmundes reduziert werden. Der geeignete Wert ist anhand weniger Versuche festlegbar.Canister vacuum cleaners become even more effective Air performance used, the inflow cross section of the Suction mouth can be reduced. The appropriate value is based on fewer attempts can be determined.
