Abstract

For more convenient servicing, an active vacuum cleaner nozzle having, in particular, a brush roller (4), a toothed belt drive (5) and an integrated electric motor or pneumatic drive is constructed in such a way that the upper part (2) of the housing is hinged to the lower part (3) of the housing so that it can be pivoted and folded down and locked in the closed position. In this case, the locking is preferably effected by pivoting and gripping over the pivotably hinged suction pipe connection nozzle (1). The drive motor and the gear mechanism for the drive of the brush roller are encapsulated in one or two separate housings inside the vacuum cleaner nozzle housing in such a way that said housings are likewise opened and exposed for servicing purposes when the upper part of the nozzle housing has been pivoted away. <IMAGE>

Description

Die Erfindung betrifft eine aktive Staubsaugerdüse der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to an active vacuum cleaner nozzle mentioned in the preamble of claim 1.

Gegenüber sogenannten statischen Staubsaugerdüsen, d.h. Düsen, die ohne Hilfselemente lediglich saugend reinigen, haben sich sogenannte aktive Staubsaugerdüsen, d.h. Düsen durchgesetzt, die innerhalb der Düse selbst zusätzlich zur Saugwirkung eine aktiv reinigende Wirkung erzeugen. Verbreitet sind zu diesem Zweck elektromotorisch oder pneumatisch angetriebene Bürstenwalzen im Einsatz.Compared to so-called static vacuum cleaner nozzles, i.e. Nozzles that only vacuum clean without auxiliary elements have so-called active vacuum cleaner nozzles, i.e. Nozzles prevail, which generate an active cleaning effect in addition to the suction effect within the nozzle itself. Electromotive or pneumatically driven brush rollers are widely used for this purpose.

In diesem Sinne betrifft die vorliegende Erfindung speziell eine Staubsaugerdüse mit zusätzlicher, angetriebener Bürstenwalze.In this sense, the present invention relates specifically to a vacuum cleaner nozzle with an additional, driven brush roller.

Bei aktiven Staubsaugerdüsen dieser Art muß für den Komfort einer verbesserten Reinigungswirkung die Unbequemlichkeit einer Wartung der Düse hingenommen werden. Durch die verbesserte Aufnahmefähigkeit der Düse gelangen nicht nur feinste Staubpartikel, sondern auch gröbere Partikel, Fäden und verfilzte Fasern in die Düse, die insbesondere im Bürstenbereich und, insbesondere bei Turbinenantrieben, auch in Turbinenbereich zu Beeinträchtigungen der freien Drehbarkeit der Walze bzw. der Turbinenräder führen können.With active vacuum cleaner nozzles of this type, the inconvenience of maintenance of the nozzle must be accepted for the convenience of an improved cleaning effect. Due to the improved absorption capacity of the nozzle, not only the finest dust particles, but also coarser particles, threads and matted fibers get into the nozzle, which in particular in the brush area and, in particular in the case of turbine drives, also in the turbine area impair the free rotation of the roller or the turbine wheels can.

Bei einer bekannten Düse dieser Art ist der Innenraum der Düse mit den aktiven Zusatzelementen durch Abschrauben und Abnehmen der Bodenplatte der Düse zugänglich. Für den praktischen Einsatz einer solchen Düse im Haushalt ist eine solche Wartungsvorkehrung nicht besonders benutzerfreundlich, da sie nicht nur das umständliche Lösen und Wiederbefestigen mehrerer Schrauben, sondern zunächst auch das Vorhandensein eines passenden Schraubendrehers erfordert.In a known nozzle of this type, the interior of the nozzle with the active additional elements is accessible by unscrewing and removing the base plate of the nozzle. For the practical use of such a nozzle in the household, such a maintenance arrangement is not particularly user-friendly, since it not only requires the laborious loosening and reattaching of several screws, but also first of all the presence of a suitable screwdriver.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine aktive Staubsaugerdüse der eingangs beschriebenen Art zu schaffen, die eine bequeme, benutzerfreundliche Wartung und Zugänglichkeit des gesamten Düseninnenraums mit allen seinen Funktionselementen ermöglicht.Starting from this prior art, the invention has for its object to provide an active vacuum cleaner nozzle of the type described above, which enables convenient, user-friendly maintenance and accessibility of the entire nozzle interior with all of its functional elements.

Zur Lösung dieser Aufgabe ist nach der Erfindung das Gehäuseoberteil schwenkbar am Gehäuseunterteil des zweiteiligen Düsengehäuses in der Weise angelenkt, daß das Gehäuseoberteil zwischen einer lösbar verriegelbaren und das Gehäuseinnere verschließenden ersten Stellung und einer im Gehäuseinneren die Bürstenwalze, das Getriebe und den Antrieb freilegenden zweiten Stellung verschwenkbar ist.To achieve this object, according to the invention, the upper housing part is pivotally articulated on the lower housing part of the two-part nozzle housing in such a way that the upper housing part can be pivoted between a releasably lockable first position which closes the inside of the housing and a second position which exposes the brush roller, the transmission and the drive inside is.

Es ist bekannt und üblich, insbesondere bei Bodenstaubsaugern ein stets planes Aufliegen der Gleitplatte oder einer in anderer Weise ausgebildeten Saugkanalöffnung auf der zu reinigenden Oberfläche dadurch zu gewährleisten, daß der üblicherweise über eine Steckmuffenverbindung zu einem Saugrohrstutzen erfolgende Anschluß des Saugrohrs innerhalb eines für den normalen Betrieb benötigten Schwenkwinkelbereich verschwenkbar erfolgt. Dabei ist nach einer Ausgestaltung der Erfindung der Saugrohranschlußstutzen zwischen einer ersten, das Gehäuseoberteil verriegelnden und einer zweiten, das Gehäuseoberteil entriegelnde Stellung verschwenkbar am Gehäuseunterteil so angelenkt, daß die das Düsengehäuseoberteil entriegelnde Schwenkstellung des Saugrohranschlußstutzens in einem Schwenkwinkelbereich liegt, der außerhalb des für den bestimmungsgemäßen Arbeitsmodus der Düse benötigten Schwenkwinkelbereichs liegt.It is known and customary, particularly in the case of canister vacuum cleaners, to ensure that the sliding plate or a suction channel opening formed in a different manner always lies flat on the surface to be cleaned, in that the connection of the suction pipe, which usually takes place via a push-in socket connection to a suction pipe socket, is within a connection for normal operation required swivel angle range is pivotable. According to one embodiment of the invention, the intake manifold connection piece is pivotably articulated on the lower housing part between a first position that locks the upper housing part and a second position that unlocks the upper housing part in such a way that the pivoting position of the intake manifold connection piece unlocking the upper part of the nozzle housing lies in a swivel angle range that is outside of the intended working mode the swivel angle required for the nozzle.

Diese Art der Gehäuseverriegelung erübrigt konstruktiv aufwendige und kostenerhöhende zusätzliche Verriegelungsmechanismen ebenso wie preisgünstige, aber weniger stabile federnde Schnappverschlüsse.This type of housing locking eliminates the need for structurally complex and cost-increasing additional locking mechanisms, as well as inexpensive, but less stable, resilient snap locks.

Um ein auch versehentliches Öffnen des Düsengehäuses bei dieser Art der Verriegelung praktisch auszuschließen, ist am Ende des für den Arbeitsmodus benötigten Schwenkwinkelbereichs und vor dem Beginn des das Gehäuse öffnenden Schwenkwinkelbereichs des Saugrohranschlußstutzens ein federnd überwindbarer Rastanschlag vorgesehen. Im einfachsten Fall handelt es sich hierbei um funktionsgerecht dimensionierte und kooperativ positionierte flache Rippen auf den Gleitflächen des Riegelmechanismus. Gleichereise können solche Rastpunkte aber auch durch federbeaufschlagte Rastkugeln oder in beliebiger anderer an sich bekannter Weise realisiert werden.In order to practically exclude an inadvertent opening of the nozzle housing with this type of locking, a spring stop that can be overcome is provided at the end of the swivel angle range required for the working mode and before the start of the swivel angle range of the intake manifold connection opening. In the simplest case, these are functionally dimensioned and cooperatively positioned flat ribs on the sliding surfaces of the locking mechanism. Likewise, such locking points can also be realized by spring-loaded locking balls or in any other known manner.

Aus Gründen der Sicherheit der so herstellbaren Verriegelung, aber insbesondere auch aus Gründen einer besseren pneumatischen Abdichtung des Inneren des Düsengehäuses ist diese Verriegelung des Düsengehäuseoberteils durch den Schwenklagerbock des Saugrohranschlußstutzens nach Art einer Flächendichtung mit breiten, komplementär übereinandergreifenden Riegelflächen ausgebildet.For the safety of the locking mechanism that can be produced in this way, but in particular also for better pneumatic sealing of the interior of the nozzle housing, this locking of the upper part of the nozzle housing is designed in the manner of a surface seal with wide, complementary overlapping locking surfaces by the swivel bearing block of the intake manifold connection piece.

Insbesondere, wenn der Antrieb der Bürstenwalze eine Turbine ist, ist dieser Schwenklagerbereich des Saugrohranschlußstutzens vorzugsweise weiterhin gleichzeitig als Teil eines Antriebsgehäuses, speziell also als Teil des Turbinengehäuses, in aller Regel also als Zylindermantelsegment mit einer Öffnung zum Saugrohranschlußstutzen ausgebildet. Mit anderen Worten, der Schwenklagerbock des Saugrohranschlußstutzens ist nach der hier beschriebenen Ausgestaltung der Erfindung verzugsweise so ausgestaltet, also insgesamt speziell als Hohlzylinderausschnitt, daß er gleichzeitig drei Funktionen erfüllt, nämlich der Schwenklagerung des Saugrohranschlußstutzens dient, frei schwenkbarer Teil des Antriebsgehäuses, speziell Turbinengehäuses des Bürstenwalzenantriebs ist und schließlich das Düsengehäuseoberteil pneumatisch dichtend verriegelt.In particular, if the drive of the brush roller is a turbine, this swivel bearing area of the intake manifold connection piece is preferably also simultaneously formed as part of a drive housing, especially as part of the turbine housing, generally as a cylinder jacket segment with an opening to the intake pipe connection piece. In other words, according to the embodiment of the invention described here, the swivel bearing block of the intake manifold connection piece is configured so as to be so, overall specifically as a hollow cylinder cutout that it simultaneously fulfills three functions, namely the swivel mounting of the intake pipe connection piece, freely pivotable part of the drive housing, especially the turbine housing of the brush roller drive and finally the upper part of the nozzle housing is pneumatically sealed.

Weitere Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further embodiments of the invention are the subject of the dependent claims.

The invention is explained in more detail below using an exemplary embodiment in conjunction with the drawings. Show it:

in plan view the bottom part of the vacuum cleaner nozzle provided with the most important insert parts without suction pipe connection piece, nozzle-side impellers and without cover; and
Fig. 3
a schematic representation of an example of an unlockable pivot bearing of the nozzle housing cover.

Die in der Fig. 1 in Form einer schematischen Strichzeichnung dargestellte aktive Staubsaugerdüse besteht aus einem mit einem Saugrohranschlußstutzen 1 versehenen zweiteiligen Gehäuse 2,3, in dem eine Bürstenwalze 4, ein Antrieb 5 und ein Getriebe 6 angeordnet sind. In dem hier gezeigten Ausführungsbeispiel der Staubsaugerdüse ist der Antrieb 5 als Turbine und das Getriebe 6 als Zahnriehmentrieb ausgebildet.The active vacuum cleaner nozzle shown in FIG. 1 in the form of a schematic line drawing consists of a two-part housing 2, 3 provided with a suction pipe connection piece 1, in which a brush roller 4, a drive 5 and a gear 6 are arranged. In the exemplary embodiment of the vacuum cleaner nozzle shown here, the drive 5 is designed as a turbine and the gear 6 as a toothed belt drive.

Das Gehäuseoberteil ist über ein in der Fig. 3 näher erläutertes Schwenklager koaxial zur Achse 7 der Bürstenwalze 4 am unteren Gehäuseteil 3 angelenkt.The upper housing part is articulated on the lower housing part 3 via a pivot bearing, which is explained in more detail in FIG. 3, coaxially to the axis 7 of the brush roller 4.

In der Fig. 1 ist das Gehäuseoberteil in einer mittleren Schwenkstellung dargestellt, also in einer teilweise geöffneten Stellung, die noch nicht der vollständigen Öffnung, aber auch nicht dem verriegelten Zustand entspricht.In Fig. 1, the upper housing part is shown in a central pivot position, that is, in a partially open position, which does not yet correspond to the full opening, but also does not correspond to the locked state.

Zum voliständigen Öffnung wird das Düsengehäuseoberteil 2 weiter in Richtung des Pfeils 8 verschwenkt und gibt dann in der schließlich mittels eines Anschlags definierten Endstellung den Innenraum des Düsengehäuses für einen Eingriff von oben mit alien seinen Funktionsteilen vollständig frei.For full opening, the upper part of the nozzle housing 2 is pivoted further in the direction of arrow 8 and then, in the end position finally defined by means of a stop, completely releases the interior of the nozzle housing for engagement from above with all its functional parts.

Zum Verriegeln wird das Gehäuseoberteil 2 soweit entgegen der Richtung des Pfeils 8 verschwenkt, bis die gefalzte Unterkante 10 des Gehäuseoberteils auf der komplementär gefalzten Oberkante 9 des Gehäuseunterteils 3 flächenbündig eingreifend aufliegt. Bei dieser Schwenkbewegung schwenkt die saugrohranschlußstutzenseitige Stirnkante 11 des Gehäuseoberteils 2 frei an der bürstenwalzenseitigen Vorderkante 12 des nach Art eines Hohlzylindersegments ausgebildeten Lagerblocks 13 vorbei, und zwar bis zum Gehäusekantenanschlag gerade soweit, daß die zylindrische Außenfläche 14 gerade flächenbündig unter der komplementär zylindrischen Innenwandfläche 15 des Lagerblocks 13 des Saugrohranschlußstutzens 1 liegt. Zum Verriegeln des Gehäuseoberteils 2 auf dem Gehäuseunterteil 3 wird bei vollständig auf das Gehäuseunterteil 3 aufgeschwenktem Gehäuseoberteil 2 der Saugrohranschlußstutzen 1 in Richtung des Pfeiles 8 so verschwenkt, daß die zueinander komplementären Zylinderflächen 14 und 15 des Gehäuseoberteils 2 bzw. des Saugrohranschlußstutzens 1 flächenbündig aufeinander gleiten.To lock, the upper housing part 2 is pivoted against the direction of the arrow 8 until the folded lower edge 10 of the upper housing part lies flush with the complementary folded upper edge 9 of the lower housing part 3. During this pivoting movement, the intake edge connection-side end edge 11 of the housing upper part 2 swings freely past the brush edge on the front edge 12 of the bearing block 13 designed in the manner of a hollow cylinder segment, to the extent that the outer edge 14 of the housing is just flush with the complementary cylindrical inner wall surface 15 of the bearing block 13 of the intake manifold connector 1 is. To lock the upper housing part 2 on the lower housing part 3, when the upper housing part 2 is pivoted completely onto the lower housing part 3, the intake manifold connection piece 1 is pivoted in the direction of arrow 8 in such a way that the complementary cylindrical surfaces 14 and 15 of the upper housing part 2 or of the intake pipe connection piece 1 slide flush on one another.

Um ein versehentlich oder unbemerktes und unbeabsichtigtes Entriegeln des Gehäuseoberteils 2 praktisch auszuschließen, ist auf der Zylinderfläche 14 des Gehäuseoberteils 2 eine vorspringende Querrippe 16 und eine auf der Zylindermantelfläche 15 des Saugrohranschlußstutzens 1 in gleicher Weise vorspringende Querrippe 15 ausgebildet, die zur Funktionsverdeutlichung in der Fig. 1 vergrößert und nicht maßstäblich dargestellt sind. Diese Querrippen 16,17 sind so dimensioniert, daß sie einerseits einen ausreichend wirksamen und deutlich spürbaren Anschlag und Druckpunkt im Übergangsbereich zwischen dem im Arbeitsmodus genutzten Schwenkwinkelbereich und dem das Gehäuseoberteil 2 entriegelnden Schwenkwinkelbereich des Saugrohranschlußstutzens 1 markieren, andererseits aber zerstörungsfrei federelastisch überwindbar sind.In order to practically exclude inadvertent or unnoticed and unintentional unlocking of the upper housing part 2, a projecting transverse rib 16 and a transverse rib 15 projecting in the same way on the cylindrical jacket surface 15 of the intake manifold connection piece 1 are formed on the cylinder surface 14 of the upper housing part 2, which for the purpose of clarifying the function in FIG. 1 are enlarged and are not shown to scale. These transverse ribs 16, 17 are dimensioned such that, on the one hand, they mark a sufficiently effective and clearly noticeable stop and pressure point in the transition area between the swivel angle area used in the working mode and the swivel angle area of the intake manifold connection piece 1 that unlocks the upper part 2 of the housing, but on the other hand they can be overcome non-destructively by elastic means.

Die in den Figuren als Ausführungsbeispiel dargestellte Staubsaugerdüse läuft auf einem Paar vorderer Laufrollen 18 und einem Paar rückwärtiger Laufrollen 19. Dabei sind das Gehäuseoberteil 2, die Bürstenwalze 4 und die vorderern Laufrollen 18 koaxial zueinander um eine Schwenk- bzw. Rotationsachse 7 drehbar, während die Lagerzapfen für die rückwärtigen Laufrollen 19 und die Schwenklagerung für den Saugrohranschlußstutzen 1 ebenfalls koaxial auf einer Drehachse bzw. Schwenkachse 20 angeordnet sind.The vacuum cleaner nozzle shown as an exemplary embodiment in the figures runs on a pair of front rollers 18 and a pair of rear rollers 19. The upper housing part 2, the brush roller 4 and the front rollers 18 coaxially rotatable about a pivot or rotation axis 7, while the journals for the rear rollers 19 and the pivot bearing for the intake manifold connection piece 1 are also arranged coaxially on an axis of rotation or pivot axis 20.

Diese koaxiale Anordnung der Funktionselemente ist insbesondere auch aus Fig. 2 gut ersichtlich.This coaxial arrangement of the functional elements can also be seen particularly well from FIG. 2.

In der ebenfalls der Fig. 2 entnehmbaren Weise ist der Antrieb für die Bürstenwalze 4 in Form einer Zwillingsturbine mit einem rechten Turbinenlaufrad 5' und einem linken Turbinenlaufrad 5'' ausgebildet, die auf einer gemeinsamen Lagerwelle 21 laufen. Das von diesem Zwillingsturbinenantrieb 5' 5'' auf der Welle 21 abgreifbare Drehmoment wird über einen Gummizahnriehmen 22 von mittig zwischen den beiden Turbinenrädern 5' 5'' auf eine mittige Ankopplung 23 auf der Bürstenwalze 4 übertragen. Dabei ist der Zahnriementrieb 6 vollständig verkapselt in einem kanalartigen Getriebegehäuse 24 untergebracht, das horizontal zumindest im wesentlichen mittig getrennt und durch komplementäre Falze gedichtet mit seinem einen Teil integraler Bestandteil des Gehäuseunterteils 3 der Saugdüse, mit seinem oberen Teil integraler Bestandteil des Gehäuseoberteils 2 der Saugdüse ist.2, the drive for the brush roller 4 is designed in the form of a twin turbine with a right-hand turbine impeller 5 ′ and a left-hand turbine impeller 5 ″, which run on a common bearing shaft 21. The torque that can be picked up by this twin turbine drive 5 '5' 'on the shaft 21 is transmitted via a rubber toothed belt 22 from the center between the two turbine wheels 5' 5 '' to a central coupling 23 on the brush roller 4. The toothed belt drive 6 is completely encapsulated in a channel-like gear housing 24, which is horizontally separated at least essentially in the center and sealed by complementary folds with one part integral part of the lower housing part 3 of the suction nozzle and with its upper part an integral part of the upper housing part 2 of the suction nozzle .

Das Gehäuseoberteil 2 ist in der aus der schematischen funktionserläuternden Fig. 3 ersichtlich über einen gleitsteinartig ausgebildeten Schwenkzapfen 25, der drehfest am Gehäuseunterteil 3 fixiert ist und eine offene Rundloch-Langloch-Kombination 26,27, die im Gehäuseoberteil 2 ausgebildet ist, so am Unterteil 3 angelenkt, daß das Gehäuseoberteil 2 in geöffneter Stellung frei vom Gehäuseunterteil 3 abziehbar ist.The upper housing part 2 can be seen in the schematic, function-explaining FIG. 3, via a sliding pin 25 which is designed in the manner of a sliding block and which is fixed in a rotationally fixed manner to the lower housing part 3 and an open round hole / elongated hole combination 26, 27 which is formed in the upper housing part 2, so on the lower part 3 hinged that the upper housing part 2 is freely removable from the lower housing part 3 in the open position.
