Description
Staubsaugerbodendüse Staubsaugerbodendüse
Die Erfindung betrifft eine Staubsaugerbodendüse nach dem Oberbegriff von Anspruch 1.The invention relates to a Staubsaugerbodendüse 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.
Eine dieser Anforderungen besteht darin, ein möglichst sanftes Gleiten der Staubsaugerbodendüse über die jeweiligen Oberflächen zu ermöglichen. Dies gilt auch im Hinblick auf das Überwinden von Kanten, beispielsweise im Bereich von Türschwellen. Um die Gleit- eigenschaften zu verbessern, sind vielfach Rollen im Bereich der Bodensohle der Staubsaugerbodendüsen angeordnet, wobei zwei vordere Bodenrollen mit identischem Abstand zur Vorderkante der Bodendüse vorgesehen sind. Schiebt man eine solche Staubsauger-
bodendüse senkrecht auf eine Kante zu, so kontaktieren die Rollen diese Kante im wesentlichen zeitgleich; dies hat ein abruptes Überwinden der Kante durch die Staubsaugerdüse zur Folge, was einen unerwünschten Kraftaufwand erfordert und insbesondere bei harten Oberflächen zu einem unerwünschten Klappern führt. Ein solches Klappern ist aus denselben Gründen auch zu verzeichnen, wenn Vertiefungen in Oberflächen zu überwin- den sind, beispielsweise bei Noppenböden, denn auch dann wird häufig der Fall eintreten, dass die Rollen gleichzeitig in die Vertiefungen einsinken, um dann wieder gleichzeitig aus den Vertiefungen herauszutreten.One of these requirements is to allow the most gentle possible sliding of the Staubsaugerbodendüse over the respective surfaces. This also applies with regard to overcoming edges, for example in the area of door sills. In order to improve the sliding properties, rollers are often arranged in the bottom of the vacuum cleaner floor nozzles, with two front floor rollers are provided at an identical distance from the front edge of the floor nozzle. If you push such a vacuum cleaner bottom nozzle perpendicular to an edge, the rollers contact this edge substantially simultaneously; This results in an abrupt overcoming of the edge through the vacuum cleaner nozzle, which requires an undesirable force and leads to an undesirable rattle, especially on hard surfaces. Such rattling can also be noted for the same reasons when depressions in surfaces are to be overcome, for example with studded bottoms, because even then it will often be the case that the rollers sink into the cavities at the same time and then out of the cavities again at the same time step out.
Um dieses bekannte Phänomen des Klappems zu vermeiden, wurde bereits vorgeschla- gen, die Rollen mit unterschiedlichen Abständen von der Vorderkante anzuordnen. Dieses im Hinblick auf die beschriebenen Nachteile erfolgreiche Konzept führt jedoch dazu, dass zwischen dem Saugmund und der Vorderkante des Staubsaugers ein relativ großer Bereich für die Anordnung der Rollen zur Verfügung stehen muss. Dies hat Nachteile im Hinblick auf die Frontalsaugeigenschaften des Staubsaugers, denn bei beispielsweise an eine Randleiste angestoßener Vorderkante liegt ein großer Abstand des Saugmundes von der Randleiste vor.In order to avoid this known phenomenon of folding flap, it has already been proposed to arrange the rolls at different distances from the leading edge. However, this concept, which is successful with regard to the described disadvantages, means that a relatively large area for the arrangement of the rollers must be available between the suction mouth and the front edge of the vacuum cleaner. This has drawbacks with regard to the frontal suction properties of the vacuum cleaner, because in the case of, for example, a leading edge abutted front edge there is a large distance of the suction mouth from the edge strip.
Der Erfindung liegt die Aufgabe zugrunde, eine Staubsaugerbodendüse zur Verfügung zu stellen, die die Probleme des Fugenklappems beseitigt und die gleichzeitig gute Frontal- Sorgeigenschaften aufweist.The invention has for its object to provide a Staubsaugerbodendüse available, which eliminates the problems of Fugenklappems and simultaneously has good frontal care properties.
Diese Aufgabe wird mit den Merkmalen des unabhängigen Anspruchs gelöst.This object is achieved with the features of the independent claim.
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 Staubsaugerbodendüse dadurch auf, dass die erste Bodenrolle vor dem Saugmund angeordnet ist und die zweite Bodenrolle hinter dem Saugmund angeordnet ist. Auf diese Weise wird das vorteilhafte Konzept, unter- schiedliche Abstände der Bodenrollen von der Vorderkante der Bodendüse vorzusehen, mit einer Platz sparenden Anordnung der Rollen kombiniert. Diese Platzeinsparung betrifft insbesondere den vor dem Saugmund für die Unterbringung einer Rolle erforderlichen
Bereich. Da die zweite Rolle hinter dem Saugmund angeordnet ist, kann dieser Bereich vor dem Saugmund sehr klein ausgebildet werden.The invention is based on the generic Staubsaugerbodendüse in that the first bottom roll is arranged in front of the suction mouth and the second bottom roll is arranged behind the suction mouth. In this way, the advantageous concept of providing different spacings of the floor rolls from the front edge of the floor nozzle is combined with a space-saving arrangement of the rolls. This space saving concerns in particular the front of the suction mouth required for the accommodation of a roll Area. Since the second roller is arranged behind the suction mouth, this area can be made very small in front of the suction mouth.
Nützlicherweise ist vorgesehen, dass der Saugmund im Bereich der ersten Bodenrolle einen größeren Abstand zur Vorderkante aufweist als im Bereich der zweiten Bodenrolle. Der größere Abstand zur Vorderkante im Bereich der ersten Rolle dient dazu, die erste Rolle unterzubringen. Da dieser größere Abstand im Bereich der zweiten Rolle nicht erforderlich ist, kann sich der Saugmund im Bereich der zweiten Rolle der Vorderkante nähern, um so gute Frontalsaugeigenschaften zur Verfügung zu stellen.Usefully, it is provided that the suction mouth in the region of the first bottom roll has a greater distance from the front edge than in the region of the second bottom roll. The greater distance from the leading edge in the area of the first roller serves to accommodate the first roller. Since this greater distance in the region of the second roller is not required, the suction mouth can approach in the area of the second roller of the leading edge, so as to provide good Frontalsaugeigenschaften.
Beispielsweise kann dies dadurch realisiert sein, dass der Saugmund zur Bereitstellung der unterschiedlichen Abstände eine Krümmung aufweist.For example, this can be realized in that the suction mouth to provide the different distances has a curvature.
Ebenfalls ist es denkbar, dass der Saugmund zur Bereitstellung der unterschiedlichen Abstände eine Ausnehmung aufweist, in der die erste Bodenrolle angeordnet ist.It is also conceivable that the suction mouth for providing the different distances has a recess in which the first bottom roll is arranged.
Die Erfindung ist in besonders vorteilhafter Weise dadurch weitergebildet, dass weitere Bodenrollen hinter der ersten und der zweiten Bodenrolle angeordnet sind, die denselben Abstand zur Vorderkante aufweisen. Insbesondere im Hinblick auf die Hinterrollen ist es nützlich, diese mit demselben Abstand zur Vorderkante auszustatten, da dies die Gleitei- genschaften der Staubsaugerbodendüse verbessert. Da die hinteren Rollen vielfach größer ausgebildet sind als die vorderen Rollen, gleiten diese ohnehin leicht über Unebenheiten im Boden.The invention is further developed in a particularly advantageous manner in that further bottom rollers are arranged behind the first and the second bottom roller, which have the same distance from the front edge. Especially with regard to the rear rollers, it is useful to equip them with the same distance from the front edge, since this improves the sliding properties of the vacuum cleaner floor nozzle. Since the rear rollers are designed to be much larger than the front rollers, they slide easily over bumps in the ground anyway.
Die Erfindung wird nun mit Bezug auf die begleitenden Zeichnungen anhand einer beson- ders bevorzugten Ausführungsform beispielhaft erläutert.The invention will now be described by way of example with reference to the accompanying drawings with reference to a particularly preferred embodiment.

Figur 1 zeigt eine perspektivische Darstellung einer erfindungsgemäßen Staubsaugerbo- dendüse 10 mit Blick auf ihre Oberseite. Figur 2 zeigt eine perspektivische Darstellung einer erfindungsgemäßen Staubsaugerbodendüse 10 mit Blick auf ihre Unterseite, und Figur 3 zeigt eine Draufsicht auf die Unterseite einer erfindungsgemäßen Staubsaugerbodendüse 10. Die Staubsaugerbodendüse 10 hat eine sich quer zur Hauptbewegungsrichtung der Staubsaugerbodendüse 10 erstreckende Vorderkante 16. Auf der Oberseite der Staubsaugerbodendüse 10 sind Bedienelemente 26, 28 angeordnet, die beispielsweise dem Anheben und dem Absenken einer Borstenleiste 28 dienen können. Über einen Saugrohrstutzen 30 lässt sich die Staubsaugerbodendüse 10 mit einem Saugrohr eines Staubsaugers verbinden. Der Saugrohrstutzen 10 mündet in einen in der Staubsaugerbodendüse 10 vorgesehenen Saugkanal 12, wobei dieser wiederum in einem sich öffnen- dem Saugmund 14 endet. An der Staubsaugerbodendüse 10 sind vier Bodenrollen angeordnet, nämlich zwei vordere Bodenrollen 18, 20 und zwei hintere Bodenrollen 22, 24. Die hinteren Bodenrollen 22, 24 weisen zur Vorderkante 16 der Staubsaugerbodendüse 10 denselben Abstand auf. Im Gegensatz hierzu weisen die vorderen Bodenrollen 18, 20 unterschiedliche Abstände zur Vorderkante 16 auf. Die erste Bodenrolle 18 hat einen klei- neren Abstand von der Vorderkante 16 als die zweite Bodenrolle 20. Um den vor dem Saugmund 14 erforderlichen Bereich zur Unterbringung der Bodenrollen 18, 20 möglichst gering zu halten, ist nur die erste Bodenrolle 18 vor dem Saugmund 14 angeordnet. Die zweite Bodenrolle 20 ist hinter dem Saugmund 14 platziert. Um die zweite Bodenrolle 20 im Hinblick auf die Gleiteigenschaften der Staubsaugerbodendüse 10 dennoch mit hinrei- chend geringem Abstand von der Vorderkante 16 anordnen zu können, ist der Saugmund 14 gekrümmt ausgebildet, das heißt, er hat im Bereich der zweiten Bodenrolle 20 einen geringeren Abstand von der Vorderkante 16 als im Bereich der ersten Bodenrolle 18. Außerdem, um den Saugmund im Hinblick auf die Frontalsorgeigenschaften überall möglichst nah an der Vorderkante 16 anordnen zu können, ist im Bereich der ersten Bodenrol- Ie 16 eine weitere Verschmälerung des Saugmundes 14 vorgesehen, die auch als Ausnehmung oder teilweise Ausnehmung des Saugmundes bezeichnet werden kann.
Die in der vorstehenden Beschreibung, in den Zeichnungen, sowie in den Ansprüchen offenbarten Merkmale der Erfindung können sowohl einzeln als auch in beliebiger Kombination für die Verwirklichung der Erfindung wesentlich sein.FIG. 1 shows a perspective view of a vacuum cleaner nozzle 10 according to the invention with a view of its upper side. FIG. 2 shows a perspective view of a vacuum cleaner floor nozzle 10 according to the invention with a view of its underside, and FIG. 3 shows a plan view of the underside of a vacuum cleaner floor nozzle 10 according to the invention. The vacuum cleaner floor nozzle 10 has a front edge 16 extending transversely to the main movement direction of the vacuum cleaner floor nozzle 10 Staubsaugerbodendüse 10 are controls 26, 28 are arranged, which can serve, for example, the raising and lowering of a bristle strip 28. About a Saugrohrstutzen 30, the Staubsaugerbodendüse 10 can connect to a suction pipe of a vacuum cleaner. The Saugrohrstutzen 10 opens into a provided in the Staubsaugerbodendüse 10 suction channel 12, which in turn ends in an open-suction port 14. Four floor rollers are arranged on the vacuum cleaner floor nozzle 10, namely two front floor rollers 18, 20 and two rear floor rollers 22, 24. The rear floor rollers 22, 24 are at the same distance from the front edge 16 of the vacuum cleaner floor nozzle 10. In contrast, the front bottom rollers 18, 20 at different distances from the front edge 16. The first floor roller 18 has a smaller distance from the front edge 16 than the second floor roller 20. In order to keep the area required for accommodating the floor rollers 18, 20 as small as possible in front of the suction mouth 14, only the first floor roller 18 is in front of the suction mouth 14 arranged. The second bottom roll 20 is placed behind the suction mouth 14. In order to still be able to arrange the second bottom roll 20 sufficiently far from the front edge 16 with regard to the sliding properties of the vacuum cleaner floor nozzle 10, the suction mouth 14 is curved, that is to say it has a smaller distance in the region of the second bottom roll 20 In addition, in order to be able to arrange the suction mouth as close as possible to the front edge 16 with regard to the frontal pelvic properties, a further narrowing of the suction mouth 14 is provided in the area of the first floor roller 16 Also may be referred to as a recess or partial recess of the suction mouth. The features of the invention disclosed in the foregoing description, in the drawings and in the claims may be essential to the realization of the invention either individually or in any combination.
