Description

Staubsaugerdüse vacuum cleaner nozzle
Die Erfindung betrifft eine Staubsaugerdüse nach dem Oberbegriff von Anspruch 1.The invention relates to a vacuum cleaner nozzle according to the preamble of claim 1.
Die verschiedenen Staubsaugertypen gemäß dem Stand der Technik lassen sich prinzi- piell in zwei unterschiedliche Bauformen unterteilen:The various vacuum cleaner types according to the prior art can basically be subdivided into two different designs:
Bei sogenannten Bodenstaubsaugern sind in einem zumeist auf Rollen gelagerten Gehäuse Motor, Gebläse, Filtereinheit und elektronische Einrichtungen angeordnet. Ein oft teleskopartig in der Länge verstellbares Saugrohr ist an einem Ende mittels eines flexiblen Saugschlauchs mit dem Gehäuse beziehungsweise dem Gebläse des Bodenstaubsaugers verbunden und weist an seinem anderen Ende eine Bodendüse auf, die mit der zu reinigenden Oberfläche in Kontakt tritt.In so-called canister vacuum cleaners, the motor, blower, filter unit and electronic devices are arranged in a housing, which is usually mounted on rollers. An often telescopically adjustable in length suction pipe is connected at one end by means of a flexible suction hose to the housing or the blower of the vacuum cleaner and has at its other end to a floor nozzle, which comes into contact with the surface to be cleaned.
Eine zweite Bauform bilden die sogenannten Handstaubsauger. Im Unterschied zu den Bodenstaubsaugern ist hier das Saugrohr starr mit dem Staubsaugergehäuse verbunden. Auch hier sind Motor, Gebläse, Elektrik und Filtereinheit in dem Gehäuse untergebracht. Dieses weist zusätzlich auf der dem Saugrohranschluss gegenüberliegenden Seite einen in Verlängerung des Saugrohrs angebrachten Stiel zur Handhabung auf.A second design form the so-called hand vacuum cleaner. In contrast to the cylinder vacuum cleaners here, the suction pipe is rigidly connected to the vacuum cleaner housing. Again, engine, blower, electrical and filter unit are housed in the housing. This additionally has on the side opposite the suction pipe connection on an extension of the suction pipe attached handle for handling.
Mittels der Bodendüse wird der von Motor und Gebläse erzeugte Unterdruck auf die zu reinigende Oberfläche angewendet. Dabei handelt es sich in der Regel entweder um harte, glatte Oberflächen von Bodenbelägen wie Parkett, PVC, Stein etc. oder um textile O- berflächen wie etwa Teppichböden, Möbelpolster oder dergleichen. Die unterschiedliche Beschaffenheit der Oberfläche stellt teilweise gegensätzliche Anforderungen an die Funk- tionalität der Bodendüse.By means of the floor nozzle, the negative pressure generated by the motor and blower is applied to the surface to be cleaned. These are usually either hard, smooth surfaces of floor coverings such as parquet, PVC, stone, etc., or textile surfaces such as carpets, furniture upholstery or the like. The different nature of the surface sometimes places conflicting demands on the functionality of the floor nozzle.
Für spezielle Reinigungsaufgaben stehen im Allgemeinen Wechseldüsen zur Verfügung. Beispielsweise sind Fugendüsen mit einem rohrartigen sich verschmälernden Endbereich sowie Möbelpinsel mit im Bereich der Öffnung angeordneten weichen Borsten bekannt. Diese Wechseldüsen liegen handelsüblichen Staubsaugern standardmäßig bei, häufig in dafür vorgesehenen Ausnehmungen im Gehäuse, wobei in diesen Ausnehmungen zu- meist Halterungen beziehungsweise speziell ausgeformte Aussparungen vorgesehen sind; die Bereiche sind häufig insgesamt durch eine Klappe abgedeckt.For special cleaning tasks are generally change nozzles available. For example, crevices with a tubular narrowing end portion and furniture brush with arranged in the region of the opening soft bristles are known. These alternating nozzles are standard on standard vacuum cleaners, often in recesses provided in the housing, whereby these recesses usually holders or specially shaped recesses are provided; The areas are often covered in total by a flap.
Aufgrund der Vielzahl möglicher Reinigungsaufgaben und im Hinblick darauf ausgestalteter Düsen, besteht ein gewisser Platzbedarf für solche Düsen zur Unterbringung im Staubsauger, der den generellen Bestrebungen nach einer Einsparung von Bauraum entgegensteht.Due to the large number of possible cleaning tasks and nozzles designed for this purpose, there is a certain amount of space required for such nozzles to be accommodated in the vacuum cleaner, which counteracts the general efforts to save space.
Ein weiterer Nachteil bei derartigen Wechseldüsen des Standes der Technik besteht darin, dass das Wechseln der Düsen mühsam ist. Will man beispielsweise beim Reinigen eines Möbelstücks mit Hilfe des Möbelpinsels nur kurzzeitig eine Fugendüse zum Einsatz bringen, so ist es erforderlich, den Möbelpinsel vom Saugrohr abzunehmen, die Fugendüse aus ihrer "Garage" zu entnehmen, den Möbelpinsel in der "Garage" unterzubringen und dann die Fugendüse mit dem Saugrohr zusammenzustecken. Selbstverständlich ist es auch möglich, sich das zwischenzeitliche Unterbringen der Düsen an ihren Aufbewah- rungsorten zu ersparen, wobei dies jedoch die Gefahr des Verlusts beziehungsweise der nicht Auffindbarkeit bei Bedarf bewirkt.Another drawback with such prior art alternating nozzles is that changing the nozzles is cumbersome. Will you, for example, when cleaning a piece of furniture using the furniture brush only briefly a crevice tool used, it is necessary to remove the furniture brush from the suction pipe, remove the crevice tool from their "garage" to accommodate the furniture brush in the "garage" and then put the crevice nozzle together with the suction tube. Of course, it is also possible to avoid the temporary placement of the nozzles at their storage locations, but this causes the risk of loss or non-findability when needed.
Der Erfindung liegt die Aufgabe zugrunde, die Unterbringung von Wechseldüsen platzsparend zu realisieren und gleichzeitig die Handhabbarkeit des Staubsaugers insgesamt zu verbessern.The invention has for its object to realize the placement of exchangeable nozzles to save space while improving the overall handling of the vacuum cleaner.
Diese Aufgabe wird mit den Merkmalen der unabhängigen Ansprüche gelöst.This object is achieved with the features of the independent claims.
Vorteilhafte Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen ange- geben.Advantageous embodiments of the invention are specified in the dependent claims.
Die Erfindung baut auf der gattungsgemäßen Staubsaugerdüse dadurch auf, dass der zweite Endbereich ebenfalls mit dem Saugrohrende zusammensteckbar ist und dass der erste Endbereich ebenfalls eine Ausgestaltung aufweist, die einer Reinigungsaufgabe des ersten Endbereichs angepasst ist. Beide Endbereiche der Staubsaugerdüse sind somit zur Wahrnehmung von Reinigungsaufgaben ausgestaltet, und ebenfalls sind beide Endbereiche der Staubsaugerdüse mit dem Saugrohr des Staubsaugers zusammensteckbar. Folglich liegt eine Kombidüse vor, die die Funktionen von zwei Düsen in einem Teil verei- nigen kann, so dass letztlich Raum für die Unterbringung von derartigem Staubsaugerzubehör eingespart wird.The invention is based on the generic vacuum cleaner nozzle in that the second end region is also plugged together with the Saugrohrende and that the first end region also has a configuration that is adapted to a cleaning task of the first end portion. Both end portions of the vacuum cleaner nozzle are thus configured to perform cleaning tasks, and also both end portions of the vacuum cleaner nozzle with the suction pipe of the vacuum cleaner can be plugged together. Consequently, there is a combination nozzle that combines the functions of two nozzles in one part. nigen, so that ultimately space for the accommodation of such vacuum cleaner accessories is saved.
In diesem Zusammenhang ist es insbesondere von Vorteil, dass die Reinigungsaufgabe und die Ausgestaltung und des ersten Endbereichs von der Reinigungsaufgabe und der Ausgestaltung des zweiten Endbereichs verschieden sind. Auch wenn es möglich ist, beide Endbereiche gleich auszugestalten, so dass diese dieselben Reinigungsaufgaben wahrnehmen können - dies kann beispielsweise bei verschleiß- beziehungsweise verschmutzungsanfälligen Ausgestaltungen der Endbereiche sinnvoll sein, um nach Verschleiß beziehungsweise Verschmutzung den anderen Endbereich benutzen zu können - ist es doch von besonderem Vorteil, die Endbereiche unterschiedlich auszugestalten, da dann zwei Zubehörteile durch ein einziges ersetzt werden können.In this context, it is particularly advantageous that the cleaning task and the configuration and the first end portion of the cleaning task and the configuration of the second end portion are different. Even if it is possible to design both end regions the same, so that they can perform the same cleaning tasks - this may be useful, for example, in wear-prone or contamination-prone embodiments of the end regions to use after wear or contamination of the other end - it is still of particular Advantage to design the end areas differently, because then two accessories can be replaced by a single.
Es ist nützlich, dass der erste Endbereich auf das Saugrohrende aufsteckbar ist. Dies ist die übliche Art, ein Saugrohr mit einer Staubsaugerdüse zusammenzustecken. Folglich kann der funktionale zweite Endbereich der Staubsaugerdüse in herkömmlicher Weise ausgestaltet sein.It is useful that the first end portion is attachable to the Saugrohrende. This is the usual way to assemble a suction tube with a vacuum cleaner nozzle. Consequently, the functional second end portion of the vacuum cleaner nozzle may be configured in a conventional manner.
In diesem Zusammenhang ist es sinnvoll, dass der erste Endbereich einen Innenkonus aufweist. Ein solcher Innenkonus, vorzugsweise in Verbindung mit Klemmstegen bietet der Kombidüse einen festen Halt auf dem Handgriff.In this context, it makes sense that the first end region has an inner cone. Such an inner cone, preferably in conjunction with clamping webs of the combi nozzle provides a firm grip on the handle.
Weiterhin ist es möglich, dass der zweite Endbereich in das Saugrohrende einsteckbar ist. Unter der Voraussetzung einer Ausgestaltung des zweiten Endbereichs mit geringem Durchmesser ist es möglich, diesen in das Saugrohrende einzuführen, und so eine ande- re Befestigungsweise der Düse am Rohr zu realisieren.Furthermore, it is possible that the second end region can be inserted into the suction tube end. Provided that the second small-diameter end region is configured, it is possible to introduce it into the suction pipe end, thus realizing another manner of fastening the nozzle to the pipe.
In diesem Zusammenhang ist es dann besonders vorteilhaft, dass bei in das Saugrohrende eingestecktem zweiten Endbereich das Saugrohrende mit einem Außenkonus zusammenwirkt. Somit wird auch beim Einstecken der Düse in das Saugrohrende ein sicherer Halt gewährleistet.In this context, it is then particularly advantageous that, when the second end region is inserted into the suction tube end, the suction tube end cooperates with an outer cone. Thus, a secure hold is ensured even when inserting the nozzle in the Saugrohrende.
Vorteilhafterweise ist vorgesehen, dass der zweite Endbereich als Fugendüse ausgestaltet ist. Der zweite Endbereich, der insbesondere in das Saugrohrende einsteckbar ist, - A -Advantageously, it is provided that the second end region is designed as a crevice nozzle. The second end region, which can be inserted in particular into the suction tube end, - A -
kann als Fugendüse in besonders vorteilhafter Weise ausgebildet sein, da die Fugendüse ohnehin eine schlanke Gestalt haben soll, was deren Ausgestaltung im Hinblick auf das Einstecken in das Saugrohrende begünstigt.can be designed as a crevice nozzle in a particularly advantageous manner, since the crevice nozzle should have a slim shape anyway, which favors their design with regard to the insertion into the suction tube.
Weiterhin ist es bevorzugt, dass der erste Endbereich Borsten aufweist. Die Borsten sind im eingesteckten Zustand des Saugrohrs in den ersten Endbereich vorzugsweise kreisförmig um das Saugrohrende angeordnet - sie bilden eine Verlängerung der Staubsaugerdüse in Richtung auf das Saugrohr. Steckt man die Kombidüse andersherum mit dem Saugrohr zusammen, so steht eine zentrale Öffnung mit diese Öffnung umgebenden Borsten zur Verfügung.Furthermore, it is preferred that the first end region comprises bristles. The bristles are in the inserted state of the suction pipe in the first end region preferably arranged in a circle around the Saugrohrende - they form an extension of the vacuum cleaner nozzle in the direction of the suction pipe. If you put the combination nozzle the other way around with the suction tube, so is a central opening with this opening surrounding bristles available.
Im Zusammenhang mit der Ausgestaltung des Möbelpinsels ist es besonders nützlich, dass der Träger zumindest teilweise aus einer Hartkomponente und die Borsten zumindest teilweise aus einer Weichkomponente bestehen. Die Wahl von Komponenten mit unterschiedlichen Härtegraden für unterschiedliche Bereiche der Düse stellt eine Optimie- rung derselben hinsichtlich der Funktionalität dar. Beispielsweise kann der Träger und auch das dem Borsten abgewandten Ende der Düse aus PP, PP-GF oder dergleichen hergestellt werden. Die Borsten hingegen können beispielsweise aus TPE, PVC, Silikon, Elastomer oder ähnlichem gefertigt werden. Damit sind die tragenden Bereiche der Düse hinsichtlich ihrer tragenden Funktionalität optimiert, gleichzeitig können die Borsten aus- reichend flexibel sein. Zusätzlich entfallen auf diese Weise nach Herstellung des Trägers weitere Montageschritte, wie etwa das Anbringen von Borsten in dafür vorgesehene Aufnahmen. Ferner kann auf zusätzliche Montagewerkzeuge verzichtet werden. Gegebenenfalls geht mit der Einstückigkeit aufgrund eines Fehlens von Verbindungen und Verbindungsmaterialien, wie etwa Klebstoffen, eine höhere Zuverlässigkeit der Düse einher.In connection with the design of the furniture brush, it is particularly useful that the carrier at least partially made of a hard component and the bristles at least partially made of a soft component. The choice of components with different degrees of hardness for different areas of the nozzle represents an optimization of the same in terms of functionality. For example, the support and also the end of the nozzle facing away from the bristle can be made of PP, PP-GF or the like. The bristles, however, can be made of TPE, PVC, silicone, elastomer or the like, for example. Thus, the supporting areas of the nozzle are optimized in terms of their supporting functionality, while the bristles can be sufficiently flexible. In addition, this eliminates after assembly of the carrier further assembly steps, such as the attachment of bristles in designated recordings. Furthermore, can be dispensed with additional assembly tools. Optionally, the integrity due to a lack of joints and bonding materials, such as adhesives, results in greater nozzle reliability.
Gemäß einer bevorzugten Ausführungsform ist vorgesehen, dass die Borsten an den Träger in einem Spritzgussverfahren angespritzt sind. Mit Hilfe des Spritzgussverfahrens können die Borsten besonders einfach und kostengünstig an den Träger angeformt werden.According to a preferred embodiment, it is provided that the bristles are injection-molded onto the carrier in an injection molding process. With the help of the injection molding process, the bristles can be particularly easily and inexpensively molded to the carrier.
Bei einer vorteilhaften Ausführungsform ist vorgesehen, dass die Borsten im Wesentlichen kegelförmig sind. Dabei ist insbesondere vorgesehen, dass die breitere Kegelbasis den Anbindungspunkt der Borsten an das Träger bildet und die gegebenenfalls auch stumpfe Kegelspitze der zu reinigenden Oberfläche zugewandt ist. Auf diese Weise kann eine ausreichende Flexibilität und Luftdurchlässigkeit der Borsten erreicht werden, während gleichzeitig für eine ausreichend stabile Anformung der Borsten an den Träger gesorgt wird.In an advantageous embodiment it is provided that the bristles are substantially conical. It is provided in particular that the wider cone base forms the point of attachment of the bristles to the carrier and optionally also blunt conical tip facing the surface to be cleaned. In this way, sufficient flexibility and air permeability of the bristles can be achieved, while at the same time providing a sufficiently stable forming of the bristles to the carrier.
Des Weiteren kann vorteilhaft vorgesehen sein, dass die Borstenenden abgerundet sind. Dies erhöht die Lebensdauer der Borsten und damit auch die der Borstenleiste und schont empfindliche Oberflächen bei deren Reinigung.Furthermore, it can be advantageously provided that the bristle ends are rounded. This increases the service life of the bristles and thus also of the bristle strip and protects sensitive surfaces during their cleaning.
Die Erfindung wird nun mit Bezug auf die begleitenden Zeichnungen anhand bevorzugter Ausführungsformen beispielhaft erläutert.The invention will now be described by way of example with reference to the accompanying drawings with reference to preferred embodiments.

Figur 3 zeigt eine perspektivische Darstellung mit Blick auf ein anderes Ende einer erfindungsgemäßen Staubsaugerdüse. Die Staubsau- gerdüse 10 umfasst einen im Wesentlichen rohrförmigen Träger 12. Einer der Endbereiche 14 der Staubsaugerdüse 10 weist einen größeren Durchmesser als der andere Endbereich 16 auf. Der erste Endbereich 14 ist mit Borsten 22 ausgestattet, so dass dieser Endbereich als Möbelpinsel dienen kann, während der andere Endbereich 16 die Form einer Fugendüse hat. Aufgrund der Durchmesserrelation von Fugendüse und erweitertem Endbereich 14 mit Borsten 22 ist ein Saugrohrende eines Staubsaugers in den erweiterten Endbereich 14 einsteckbar, während das Saugrohrende auf den Endbereich 16 mit geringerem Durchmesser aufsteckbar ist. Um den Zusammenhalt von Saugrohrende und Fugendüse bei eingestecktem zweiten Endbereich 16 in das Saugrohrende zu verbes- sern, kann ein Außenkonus 20 vorgesehen sein, der mit dem Saugrohrende im eingesteckten Zustand zusammenwirkt. Ebenfalls kann ein Innenkonus 18 mit einem oder mehreren Klemmstegen 26, die an dem Innenkonus 18 angeordnet sind, vorgesehen sein, um den Zusammenhalt der Staubsaugerdüse 10 mit dem Saugrohrende bei eingestecktem Saugrohrende in die Staubsaugerdüse 10 zu verbessern. Die Borsten 22 sind schräg nach Außen angestellt, um bei Verwendung der Staubsaugerdüse als Fugendüse ein unbehindertes Einstecken des Saugrohrendes sicherzustellen. Die Borsten 22 umgeben den ersten Endbereich 14 kreisförmig, und es sind beim dargestellten Ausführungsbeispiel drei Reihen von Borsten vorgesehen. Die Borsten 22 sind kegel- beziehungsweise kegel- stumpfförmig, wobei die Kegelspitze beziehungsweise das dünnere Ende des Kegel- stumpfs von der Staubsaugerdüse 10 wegzeigen. Vorzugsweise sind die Borstenenden 24 abgerundet.FIG. 1 shows a perspective side view of a vacuum cleaner nozzle according to the invention. Figure 2 shows a perspective view looking at one of the ends of a vacuum cleaner nozzle according to the invention. FIG. 3 shows a perspective view with a view of another end of a vacuum cleaner nozzle according to the invention. The vacuum cleaner nozzle 10 comprises a substantially tubular support 12. One of the end regions 14 of the vacuum cleaner nozzle 10 has a larger diameter than the other end region 16. The first end portion 14 is provided with bristles 22 so that this end portion may serve as a furniture brush while the other end portion 16 is the shape a crevice nozzle has. Due to the diameter relation of crevice nozzle and extended end region 14 with bristles 22, a suction tube end of a vacuum cleaner can be inserted into the widened end region 14, while the suction tube end can be pushed onto the end region 16 with a smaller diameter. In order to improve the cohesion of the suction tube end and crevice nozzle when the second end region 16 is inserted into the suction tube end, an outer cone 20 can be provided which cooperates with the suction tube end in the inserted state. Also, an inner cone 18 with one or more clamping webs 26 which are arranged on the inner cone 18 may be provided in order to improve the cohesion of the vacuum cleaner nozzle 10 with the Saugrohrende with inserted Saugrohrende in the vacuum cleaner nozzle 10. The bristles 22 are employed obliquely outwards to ensure unimpeded insertion of the suction pipe end when using the vacuum cleaner nozzle as a crevice tool. The bristles 22 surround the first end region 14 in a circle, and in the illustrated embodiment, three rows of bristles are provided.
