Description

Die Erfindung betrifft gemäß Oberbegriff des Anspruchs 1 eine Düse für Bodenpflegegeräte, insbesondere eine Teppich- und Bodendüse in Form einer Kombinationsdüse, die zur Reinigung von textilen Bodenbelägen und glatten Böden geeignet ist.The invention relates according to the preamble of claim 1, a nozzle for floor care appliances, in particular a carpet and floor nozzle in the form of a combination nozzle, the Cleaning of textile floor coverings and smooth floors is suitable.

Die Reinigung von Böden ist überwiegend von der Saugleistung der Bodenpflegegeräte abhängig. Diese Saugleistung wird durch die Abstimmung von Unterdruck, Luftförderung und der Form des an der Düse befindlichen Saugmundstücks bestimmt. Dieses Saugmundstück befindet sich an der dem zu reinigenden Boden zugewandten Unterseite der Düse und umfasst ein Gleitblech oder Gleitkunststoff. Das Gleitblech bildet die geformte Gleitsohle, in der ein Saugmundstück mit einem Ansaugkanal, der mindestens einen eingelassenen Luftkanal mit Saugmundkanten enthält, der auf dichten Flor textiler Fußbodenbeläge Luft strömen lässt. Vorzugsweise ist der Luftkanal des Saugmundstücks bis zur äußeren Kante der Gleitsohle ausgebildet. Des weiteren kann die Gleitsohle Träger von Abstützelementen sein, die aus Rollkörpern, Gleitflächen oder Gleitkanten, auf der die Düse gleitet, bestehen.The cleaning of floors is predominantly of the suction power of the floor care equipment dependent. This suction power is through the vote of negative pressure, air delivery and the shape of the located on the nozzle suction nozzle determined. This suction mouthpiece is located on the underside of the nozzle facing the floor to be cleaned and comprises a sliding plate or sliding plastic. The sliding plate forms the molded sliding sole in which Suction nozzle with a suction channel, the at least one recessed air duct with Contains suction mouth edges, which allows air to flow on dense pile of textile floor coverings. Preferably, the air duct of the suction mouthpiece is up to the outer edge of the sliding sole educated. Furthermore, the sliding sole can be a carrier of support elements made of Rolling bodies, sliding surfaces or sliding edges, on which the nozzle slides, exist.

Zum Aufnehmen von Fäden, Fusseln, Haaren usw. ist die Gleitsohle Träger von eingelassenen Fadenhebern, die in der Nähe des zentralen Ansaugkanals angeordnet sind. Die optimale Reinigungswirkung von Böden bzw. Saugleistung der Düse ist von der Gestaltung der Gleitsohle abhängig. Die Gesamtleistung des Bodenpflegegerätes soll hierbei nicht erhöht werden, denn dies führt zu einer erhöhten Schiebekraft (Bewegungswiderstand) der Düse auf textilen Bodenbelägen. Vielmehr soll eine Optimierung der Saugleistung in der Tiefe der Poren des textilen Bodenbelages erreicht werden. Besondere Bedeutung kommt daher dem in der Gleitsohle eingeformten Ansaugkanal und dem in der Gleitsohle integrierten Fadenheber zu. Weiterhin sind die Geometrie, die Form und die Anordnung der vorderen und hinteren Saugmundkanten sowie der Ansaug- und Luftleitkanal der Düse strömungstechnisch aufeinander abzustimmen. Saugmundkanten bilden die Strömungsabriss- oder Arbeitskanten, über welche im Betrieb angesaugte Luft in die zugehörigen Luftkanäle und von dort in den Ansaugkanal strömt.For picking up threads, lint, hair, etc., the soleplate is inlaid with support Thread lifters, which are arranged near the central intake passage. The optimal Cleaning effect of soils or suction power of the nozzle is dependent on the design of the Sliding sole dependent. The overall performance of the floor care device should not be increased here be, because this leads to an increased sliding force (resistance to movement) of the nozzle textile floor coverings. Rather, it aims to optimize the suction power in the depth of the pores the textile floor covering can be achieved. Special importance therefore comes in the Sliding sole molded suction channel and integrated in the sliding sole thread lifter. Furthermore, the geometry, the shape and the arrangement of the front and rear Saugmundkanten and the intake and air duct of the nozzle fluidically to coordinate with each other. Saugmundkanten form the stall or working edges, via which sucked in operation air into the associated air ducts and from there into the Intake channel flows.

Ein Beispiel für solch eine Düse eines Bodenpflegegerätes und deren Anordnung der Elemente Ansaugkanal, Luftkanal und Fadenheber in der Gleitsohle sind im Dokument D1 (DE 42 43 244 C2) offenbart. Bei dieser Aufbauform hat der in die Vertiefung der Gleitsohle eingelassene Fadenheber mit seiner textilen Oberfläche eine gewölbte Form und er besitzt keine ausgeprägte Saugmundkante. Nachteilig ist es bei dieser Düse, dass eine Unterbrechung der Saugmundkanten der Luftleitkanäle entsteht und dadurch auch keine durchgehende Gleitkante in der Gleitsohle vorhanden ist (siehe Fig. 4).An example of such a nozzle of a floor care device and their arrangement of the elements Intake duct, air duct and thread lifter in the soleplate are in the document D1 (DE 42 43 244 C2). In this design, the embedded in the recess of the sliding sole has Thread lifter with its textile surface a curved shape and he has no pronounced Suction mouth. The disadvantage of this nozzle, that an interruption of Saugmundkanten the air ducts formed and thus no continuous sliding edge is present in the sliding sole (see Fig. 4).

Aus weiteren Beispielen aus dem Stand der Technik der D2 (DE 43 04 6814 C2) und der D3 (DE 44 06 156 A1) ist allgemein bekannt, dass die Vertiefungen oder abgesenkten Flächenabschnitte in der Gleitsohle die Saugmundkanten des Luftkanals unterbrechen und durch die eingeklebten streifenförmigen Fadenheber keine durchgehenden Saugmundkanten entstehen. Die D4 (DE 197 30 709 C2) offenbart, dass im Mittenbereich des Staubsaugermundstücks in den Verlauf der Arbeitskanten die bekannten Fadenheber eingesetzt sind, wobei auch hier die Saugmundkanten des Saugmundstück unterbrochen sind.From further examples from the prior art of D2 (DE 43 04 6814 C2) and the D3 (DE 44 06 156 A1) is well known that the wells or lowered Area sections in the sliding sole interrupt the suction mouth edges of the air duct and through the glued strip-shaped thread lifter no continuous Saugmundkanten arise. D4 (DE 197 30 709 C2) discloses that in the middle region of the vacuum cleaner nozzle in the course of the working edges, the known thread lifters are used, and also here the suction mouth edges of the suction mouthpiece are interrupted.

In dem Dokument D5 (DE 199 00 968 C1) ist die hintere Saugmundkante im Bereich des Ansaugkanals durch eine im Strömungsraum befindliche Vertiefung unterbrochen. Dieser Nachteil soll in einer weiteren in der D5 genannten Ausführungsform (Fig. 2) beseitigt werden. Die Vertiefung in der Gleitsohle im Bereich des Ansaugkanals an der hinteren Saugmundkante wird durch Einsatz eines Kunststoffteils, welches einen Steg in ähnlicher Ausführung wie die hintere Saugmundkante des Luftkanals bildet, ausgefüllt. Hinter dem Steg befindet sich eine strömumgsbildende Vertiefung, an die sich der separate Fadenheber anschließt. Diese zwischen dem Steg, der mit Öffnungen oder Bohrungen zum Ansaugkanal unterbrochen ist, und dem ballig ausgeführten Fadenheber gelegenen Vertiefung, erhöht den Abstand zwischen Fadenheber und Steg. Der vordere Fadenheber ist zwar in eine von zwei schmalen Rippen begrenzte Aufnahmevertiefung eingesetzt. Diese Rippen dienen aber nicht als Saugmundkanten, denn sie liegen nicht auf gleicher Höhenlinie wie die angrenzenden Saugmundkanten des Luftkanals und sind mit Durchbrüchen versehen. Des weiteren handelt es sich bei den eingesetzten Fadenhebern um die bekannte ballige Ausführungsform.In document D5 (DE 199 00 968 C1), the rear suction mouth edge is in the region of Intake channel interrupted by a depression located in the flow space. This Disadvantage is to be eliminated in a further embodiment mentioned in D5 (FIG. 2). The depression in the sliding sole in the area of the intake channel at the rear suction mouth edge is made by using a plastic part, which has a bridge in similar design as the rear suction mouth edge of the air channel forms, filled. Behind the jetty is one Strömumgsbildende depression, which is followed by the separate thread lifter. These between the web, which is interrupted with openings or holes to the intake passage, and the convex thread take center, increases the distance between Thread lifter and bridge. Although the front thread lifter is in one of two narrow ribs limited recording well used. These ribs are not as Saugmundkanten, because they are not on the same contour as the adjacent Suction mouth edges of the air duct and are provided with openings. Furthermore it acts itself at the thread lifts used to the known spherical embodiment.

In der D6 (DE 199 06 137 C1) wird die in der Grundsohle im Bereich der Saugmundkanten befindliche Lücke mit Kunststoffeinsätzen, die eine randseitige Einfassung der Saugkanäle mit Abrisskanten vorsieht, ausgefüllt, wobei die Kunststoffeinsätze wiederum Vertiefungen aufweisen, in denen die separaten Fadenheber eingesetzt werden und die Abrisskanten mit Öffnungen bzw. Bohrungen versehen sind. Der hintere Fadenheber ist von der Abrisskante durch einen Strömungsraum beabstandet. Wie in der Ausführungsform in Fig. 2 dargestellt, bildet sich hinter der Abrisskante zum balligen Fadenheber eine Vertiefung, in der sich nachteilig Schmutz ansammelt.In the D6 (DE 199 06 137 C1) is in the bottom sole in the area of Saugmundkanten gap with plastic inserts, the edge-side enclosure of the suction channels with Abrisskanten provides, filled, the plastic inserts in turn wells in which the separate thread lifters are used and the tear-off edges with Openings or holes are provided. The rear thread lifter is from the trailing edge spaced by a flow space. As shown in the embodiment in FIG. 2, forms behind the spoiler edge to the convex thread lifter a recess in which disadvantageously accumulates dirt.

Aus dem Stand der Technik und aus der Praxis sind somit eine Vielzahl von Ausführungsformen bekannt, die aber alle noch mit gewissen Nachteilen behaftet sind. Insbesondere führt die Ergänzung der Bodendüse mit einem Fadenheber und dessen Integration in die Gleitsohle zu strömungstechnischen Nachteilen, da durch den Einsatz des Fadenhebers Unterbrechungen in den Luftkanälen und in der Luftführung entstehen, was wiederum Saugleistungsverluste zur Folge hat.From the prior art and from practice are thus a variety of Embodiments are known, but all still have certain disadvantages. In particular, the supplement of the floor nozzle with a thread lifter and its Integration into the soleplate to aerodynamic disadvantages, as through the use of the Thread lifter Interruptions in the air ducts and in the air duct arise what in turn results in suction power losses.

Ferner wird durch die meist ballige Ausführung der Fadenheber und durch den direkten Kontakt mit dem zu reinigenden Boden ein erhöhter Verschleiß bei dem verwendeten Schrägborstenvelour bzw. Bürstenplüsch hervorgerufen.Furthermore, the most crowned design of the thread lifter and the direct contact with the soil to be cleaned increased wear in the used Schrägborstenvelour or brush plush caused.

Weiterhin nachteilig ist, dass die Höhenlinie der Fadenheber und die Höhenlinie der Saugmundkanten in Bezug zur Ebene des zu reinigenden Bodens weit auseinander liegen und dass die zum Einbau der Fadenheber bedingte Unterbrechung der Saugmundkanten eine verschlechterte Reinigungswirkung der Staubaufnahme durch die Düse zur Folge hat.Another disadvantage is that the contour line of the thread lifter and the contour line of the Suction orifice edges are far apart in relation to the plane of the soil to be cleaned and that the installation of the thread lifter conditional interruption of Saugmundkanten a degraded cleaning effect of dust uptake by the nozzle result.

Der Erfindung stellt sich somit das Problem, eine Düse für Bodenpflegegeräte zu entwickeln, die einfach aufgebaut ist, bei der unter Verwendung eines Fadenhebers Saugleistungsverluste vermieden werden und mit der eine größere Tiefenwirkung in den Poren bei textilen Fußbodenbelägen erzielt wird.The invention thus raises the problem of developing a nozzle for floor care appliances, the is simply constructed, in which using a thread lifter suction power losses be avoided and with the greater depth effect in the pores in textile Floor coverings is achieved.

Erfindungsgemäß wird dieses Problem durch die Merkmale des Anspruchs 1 gelöst. Weitere Merkmale und Ausgestaltungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention, this problem is solved by the features of claim 1. Further Features and embodiments of the invention will become apparent from the following Dependent claims.

Eine mit den Merkmalen gemäß der Erfindung ausgebildete Bodendüse ermöglicht die Erhöhung der Effektivität der Staubaufnahme, verbessert die Saugeigenschaften der Düse und bewirkt eine bessere Tiefenreinigung der Poren von textilen Bodenbelägen.A designed with the features according to the invention floor nozzle allows the Increasing the effectiveness of dust pickup, improves the suction properties of the nozzle and causes a better deep cleaning of the pores of textile floor coverings.

Insbesondere ist dies auf die erfindungsgemäße Ausbildung des Fadenhebers mit dem eine starre Kante bildenden Steg und dem sich unmittelbar hinter dem Steg anschließenden Textilteil zurückzuführen. Der Steg kämmt bei der Reinigung eines Teppichbodens den Flor und öffnet somit den Flor zugunsten einer verbesserten Tiefenwirkung.In particular, this is the inventive design of the thread lifter with the one rigid edge-forming web and the immediately behind the web subsequent textile part due. The bridge combs the pile while cleaning a carpet and opens thus the pile in favor of an improved depth effect.

Außerdem wird durch die erfindungsgemäße Ausbildung des Fadenhebers der Verschleiß des textilen Materials verringert. Der Fadenheber ist einfach aufgebaut und lässt sich leicht auswechseln.In addition, by the inventive design of the thread lifter wear of the reduced textile material. The thread lifter is simple and easy to set up Replace.

The textile part (16, 16 ') is mounted behind the web (11) on the upwardly directed surface of the plastic part (17, 17').
The plastic part (17, 17 ') of the thread lifter (9, 10) can be connected to the textile part (16, 16') in the plastic injection molding process and additionally provides a by back injection on the support member (17, 17 ') formed web (18) for it in that the textile part (16, 16 ') is enclosed and fixed in its edge region. The textile part (16, 16 ') of the thread lifter (9, 10) is preferably a brush plush of a diagonally aligned bristled suede.

Das Textilteil (16, 16') kann mit der oberen Kante des Steges (11) auf gleicher Höhe liegen. Bei dem in Fig. 2 gezeigten Fadenheber (9) ist die Dicke bzw. Höhe des Textilteils (16, 16') so gewählt, dass die Oberkante des Textilteils (16, 16') samt Bürstenflor (16") mit der Oberkante des Steges (11) nicht ganz auf einer Höhe liegt und mit in einem geringen Abstand unterhalb der Oberkante des Steges (11) abschließt. Dies hat den Vorteil, dass die am Steg (11) gebildete Gleitkante (4) den Bürstenflor besonders gut vor Verschleiß schützt. The textile part (16, 16 ') can lie with the upper edge of the web (11) at the same height. at the thread lifter (9) shown in Fig. 2, the thickness or height of the textile part (16, 16 ') is so chosen that the upper edge of the textile part (16, 16 ') together with Bürstenflor (16 ") with the upper edge of the bridge (11) is not quite at a height and with a short distance below the upper edge of the web (11) closes. This has the advantage that at the bridge (11) formed sliding edge (4) protects the brush pile particularly well from wear.

Zum Auswechseln der Fadenheber (9, 10) aus der Ausnehmung (23) oder der Vertiefung (24) der Gleitsohle (3) besitzt der Fadenheber (9, 10), an der der Gleitsohle (3) zugewandten Seite bzw. der bodenabgewandten Seite mindestens eine Nut (21), in die ein Werkzeug zum Lösen der Verbindung eingeführt werden kann. Der eingesetzte vordere und hintere Fadenheber (9, 10) ist mit einem bodenseitigen Steg (11), der als Gleitkante (14, 15) wirkt, ausgebildet. Die Gleitkante (14, 15) des Fadenhebers (9, 10) wirkt beim Kämmen des textilen florigen Bodenbelages öffnend auf die Fasern ein und zwar unmittelbar am Ansaugkanal (4), so dass eine verbesserte reinigende Tiefenwirkung erzielt wird.For exchanging the thread lifters (9, 10) from the recess (23) or the recess (24) the sliding sole (3) has the thread lifter (9, 10), on the side facing the sliding sole (3) or the side facing away from the floor at least one groove (21) into which a tool for releasing the connection can be introduced. The inserted front and rear thread lifter (9, 10) is formed with a bottom-side web (11), which acts as a sliding edge (14, 15). The Sliding edge (14, 15) of the thread lifter (9, 10) acts when combing the textile florigen Floor covering opening on the fibers and that directly on the intake duct (4), so that an improved cleansing depth effect is achieved.

In dem Ausführungsbeispiel gemäß Fig. 3 bildet das Kunststoffteil (17, 17') des Fadenhebers (9, 10) eine Kanalwand (22, 22'), das die Lücke (23, 24) in der Gleitsohle (3) des Luftkanals (5, 6) randeinfassend im Bereich des Ansaugkanals (4) schließt. Das obere offene Ende der Kanalwand (22, 22') der bodenseitigen Stege (11) der Gleitkanten-Fadenheber (9, 10) ist als Saugmundkante (12, 13) ausgebildet. Die Saugmundkanten (12, 13) verlaufen parallel zur gemeinsamen Ebene des Bodens wie auch die Saugmundkanten (7, 8) des Luftkanals (5, 6), wodurch eine umlaufende Saugmundkante am Saugmundstück (2) für die Luftströmung entsteht. Die durchgehende vordere Saugmundkante (7, 12) und die hintere Saugmundkante (8, 13) bewirken eine Erhöhung der Effektivität der Saugleistung.In the embodiment according to FIG. 3, the plastic part (17, 17 ') of the thread lifter forms (9, 10) a channel wall (22, 22 '), the gap (23, 24) in the sliding sole (3) of the air duct (5, 6) bordering encloses in the region of the intake duct (4). The upper open end of the Channel wall (22, 22 ') of the bottom-side webs (11) of the sliding edge thread lifter (9, 10) is as Suction mouth edge (12, 13) formed. The suction mouth edges (12, 13) run parallel to the common plane of the bottom as well as the Saugmundkanten (7, 8) of the air channel (5, 6), whereby a circumferential suction mouth edge on the suction mouthpiece (2) for the air flow arises. The continuous front suction mouth edge (7, 12) and the rear suction mouth edge (8, 13) cause an increase in the effectiveness of the suction power.

Das Textilteil (16, 16') schließt unmittelbar an den Steg (11) an. Ein wesentlicher Vorteil, der durch die unmittelbare Angrenzung des Textilteils (16, 16') an den Steg (11) erzielt wird, besteht darin, dass durch die Vermeidung eines Zwischenraums und durch die Angleichung der Höhenlinie des textilen Material an die Höhenlinie der Saugmundkante (12, 13) in der horizontalen Ebene des zu reinigenden Bodens ein verbesserter Reinigungseffekt am Fadenheber (9, 10) eintritt.
Die Höhenlinie der ebenen Fläche (18) des Textilteils (16, 16') des Fadenhebers (9, 10) ist gegenüber der Höhenlinie der Saugmundkante (12, 13) bzw. des Steges (11) etwas niedriger bzw. abgesenkt, wodurch der Bodenkontakt und somit der Verschleiß des textilen Material verringert werden. Insbesondere wirkt sich dies auf glatten Böden aus, wenn die Gleitsohle (3) nicht durch zusätzliche Gleitflächen oder Rollkörper gestützt wird und der Gleitdruck direkt auf dem Fadenheber lastet.
Bei der Ausführung gemäß Fig. 3 ist der vordere Fadenheber (9) unter einem Winkel (19) leicht schräg angeordnet und er besitzt im vorderen Bereich eine Abrundung (28) bzw. Fase, um an dieser Stelle keine die Luftströmung störende Kante zu erzeugen. An der dem Luftkanal (4) zugewandten Seite besitzt der Steg (11) eine strömungsaktive Saugmundkante (12).
Der hintere Fadenheber (10) ist in der Vertiefung (24) vor der schräg abfallenden Fläche (26) der Gleitsohle angeordnet. Auch hier bildet sich eine strömungsaktive Saugmundkante (13). The textile part (16, 16 ') connects directly to the web (11). A significant advantage, which is achieved by the immediate adjacency of the textile part (16, 16 ') to the web (11), is that by avoiding a gap and by the alignment of the contour line of the textile material to the contour line of the suction mouth ( 12, 13) in the horizontal plane of the floor to be cleaned an improved cleaning effect on the thread lifter (9, 10) occurs.
The contour line of the flat surface (18) of the textile part (16, 16 ') of the thread lifter (9, 10) is slightly lower or lowered relative to the contour line of the suction mouth edge (12, 13) or the web (11), whereby the ground contact and thus the wear of the textile material can be reduced. In particular, this effect on smooth floors, if the sliding sole (3) is not supported by additional sliding surfaces or rolling elements and the sliding pressure directly on the thread lifter loads.
In the embodiment of FIG. 3, the front thread lifter (9) at an angle (19) is arranged slightly obliquely and he has in the front region a rounding (28) or chamfer to produce at this point no disturbing the air flow edge. At the air duct (4) facing side of the web (11) has a flow-active suction mouth edge (12).
The rear thread lifter (10) is disposed in the recess (24) in front of the sloping surface (26) of the sliding sole. Here, too, forms a flow-active suction mouth edge (13).
