Abstract
Description
Die Erfindung betrifft eine Saugdüse für Staubsauger.The invention relates to a suction nozzle for vacuum cleaners.
Saugdüsen für Staubsauger werden in unterschiedlichen Ausführungen in vielen Bereichen des Haushalts oder in gewerblich genutzter Umgebung eingesetzt. Sie sind beispielsweise an Bodenstaubsaugern oder Handstaubsaugern für Polstermöbel anzutreffen. Die Gestaltung einer Saugdüse kann je nach Verwendungszweck sehr unterschiedlich sein. Gemeinsam haben sie aber alle die Eigenschaften, dass sie auf der zu saugenden Fläche gleiten oder rollen und dass Teile der Saugdüse von der Saugluft durchströmt oder umströmt werden. Die Schmutzpartikel werden beim Saugen von der Saugluftströmung im Bereich der Saugdüse erfasst und über die Saugdüse und einen daran befestigten Schlauch oder ein Saugrohr einem Staubsauger zugeführt, der ein Sauggebläse und ein Sammelbehälter für Staub aufweist.Vacuum cleaner suction nozzles are used in various designs in many household or commercial environments. They can be found, for example, on vacuum cleaners or hand vacuum cleaners for upholstered furniture. The design of a suction nozzle can be very different depending on the purpose. Together they all have the properties that they slide or roll on the surface to be sucked and that parts of the suction nozzle are flowed through or sucked around by the suction air. The dirt particles are detected during suction of the Saugluftströmung in the region of the suction nozzle and supplied via the suction nozzle and a hose or a suction pipe attached to a vacuum cleaner having a suction fan and a collection container for dust.
In den Schmutzpartikeln, die beim Saugen beseitigt werden sollen, sind häufig Mikroorganismen anzutreffen, zu denen beispielsweise Bakterien oder Pilze gehören. Haften nun nach dem Saugen Schmutzpartikel in oder auf Teilen der Saugdüse, so besteht Anlass zu der Sorge, dass sich die Mikroorganismen dort vermehren, wodurch die verschmutzte Saugdüse in hygienischer Hinsicht ein Problem darstellen kann.In the dirt particles that are to be removed when sucking, are often found microorganisms, which include, for example, bacteria or fungi. If particles of dirt stick in or on parts of the suction nozzle after sucking, there is reason to worry that the microorganisms will multiply there, as a result of which the soiled suction nozzle may pose a problem in hygienic terms.
Aus
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine Saugdüse für Staubsauger anzugeben, deren hygienische Eigenschaften verbessert sind.Against this background, the present invention seeks to provide a suction nozzle for vacuum cleaners, the hygienic properties are improved.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass zumindest ein Teil der Fläche der Saugdüse mit einer Ausrüstung versehen ist, die das Ansiedeln von Mikroorganismen reduziert. In Betracht kommen insbesondere diejenigen Flächen der Düse, die beim Saugen mit Schmutzpartikeln in Berührung kommen. Vorzugsweise ist die das Ansiedeln von Mikroorganismen reduzierende Ausrüstung daher an Düsenflächen der Saugdüse vorgesehen, die der zu saugenden Fläche zugewandt sind oder beim Saugen mit der zu saugenden Fläche in Kontakt gebracht werden. Hierzu gehören insbesondere Flächen an der Unterseite der Saugdüse und bei einer Saugdüse für Bodenstaubsauger die über die Bodenfläche bewegte Gleitsohle. An der Unterseite bzw. der Gleitsohle werden Schmutzpartikel durch den Saugluftstrom aufgewirbelt, die dann z. B. durch eine elektrostatische Aufladung der Düse haften bleiben. Zu berücksichtigen sind ferner Gleitkufen oder Rollen, auf denen die Saugdüse abgestützt ist. Auch diese Elemente der Saugdüse kommen ständig mit Schmutzpartikeln in Kontakt, wodurch die Wahrscheinlichkeit, dass sich dort Mikroorganismen ansiedeln werden, entsprechend groß ist. Durch die erfindungsgemäße Ausrüstung der Düse an den entsprechenden Flächen kann eine Ansiedlung und anschließende Vermehrung von Mikroorganismen verhindert oder zumindest eingeschränkt werden und werden kritische Bereiche der Saugdüse beispielsweise vor einem Pilzbefall geschützt.This object is achieved in that at least a portion of the surface of the suction nozzle is provided with equipment that reduces the colonization of microorganisms. Particularly suitable are those areas of the nozzle that come into contact with dirt particles during suction. Preferably, the microorganism reducing equipment is therefore provided on nozzle surfaces of the suction nozzle which face the surface to be suctioned or are brought into contact with the surface to be suctioned during suction. These include in particular surfaces on the underside of the suction nozzle and in a suction nozzle for vacuum cleaners moving over the bottom surface sliding sole. At the bottom or the sliding sole dirt particles are whirled up by the suction air stream, which then z. B. stick by an electrostatic charge of the nozzle. Also to be considered are skids or rollers on which the suction nozzle is supported. These elements of the suction nozzle are constantly in contact with dirt particles, whereby the probability that microorganisms will settle there is correspondingly large. The equipment according to the invention of the nozzle on the corresponding surfaces can prevent or at least limit the colonization and subsequent multiplication of microorganisms and protect critical regions of the suction nozzle from, for example, fungal attack.
Die das Ansiedeln von Mikroorganismen reduzierende Ausrüstung ist zweckmäßig ferner an Düsenflächen der Saugdüse vorgesehen, die von Saugluft durchströmt oder umströmt werden. Hierzu gehören insbesondere der in die Gleitsohle einer Saugdüse für Bodenstaubsauger eingeformte Saugschlitz, der Saugkanal einer Saugdüse, welcher die Unterseite der Saugdüse mit einem rückwärtigen Saugrohranschlussstück verbindet, sowie das häufig als Dreh- und Kippgelenk ausgebildete Saugrohranschlussstück zur Befestigung an einem Saugrohr oder Saugschlauch. Alle diese Elemente der Saugdüse werden von Luft durchströmt, in der keimbehaftete Schmutzpartikel enthalten sind. Diese können an der Wandung der durchströmten oder umströmten Komponenten haften bleiben und dort eine Ansiedlung von Mikroorganismen, z.B. Bakterien verursachen. Die erfindungsgemäße Ausrüstung dieser Elemente wirkt einer bakteriellen Verunreinigung der Saugdüse wirksam entgegen.The settling of microorganisms reducing equipment is expediently also provided on nozzle surfaces of the suction nozzle, which are flowed through or sucked around by suction air. These include in particular the molded into the sliding sole of a suction nozzle for vacuum cleaner suction slot, the suction of a suction nozzle which connects the underside of the suction nozzle with a rear Saugrohranschlussstück, and often designed as a rotating and tilting Saugrohranschlussstück for attachment to a suction pipe or suction hose. All of these elements of the suction nozzle are traversed by air, are contained in the germ-laden dirt particles. These may adhere to the wall of the components through which flowed or flowed around and there may cause a build-up of microorganisms, e.g. Cause bacteria. The equipment according to the invention of these elements effectively counteracts bacterial contamination of the suction nozzle.
In einer bevorzugten Ausgestaltung der erfindungsgemäßen Saugdüse weist die Ausrüstung zur Reduzierung der Ansiedlung von Mikroorganismen ein Material auf, das eine biozide Wirkung hat. Durch die biozide Eigenschaft des Materials werden Mikroorganismen an ihrer Ansiedlung insofern gehindert, als sie überwiegend absterben. Das Material stellt daher für die schädlichen Mikroorganismen eine unwirtliche Umgebung dar. Die biozide Ausrüstung kann antibakteriell und/oder fungizid wirken, so dass bevorzugt Bakterien und/oder bevorzugt Pilze auf der mit der Ausrüstung versehenen Komponente der Saugdüse absterben.In a preferred embodiment of the suction nozzle according to the invention, the equipment for reducing the colonization of microorganisms, a material which has a biocidal effect. Due to the biocidal property of the material, microorganisms are prevented from settling in that they die predominantly. The material therefore represents an inhospitable environment for the harmful microorganisms. The biocidal equipment may have antibacterial and / or fungicidal activity, so that preferably bacteria and / or preferably fungi die on the component of the suction nozzle provided with the equipment.
Die Ausrüstung kann eine Oberflächenbeschichtung aufweisen oder aus einer Oberflächenbeschichtung bestehen, deren Wirkung biozid ist. Die Oberflächenbeschichtung kann direkt auf die entsprechenden Flächen der Saugdüse aufgebracht werden. Im Rahmen der Erfindung liegt es aber auch, dass eine Folie mit einer bioziden Wirkung auf Flächen der Saugdüse aufkaschiert wird.The equipment may have a surface coating or consist of a surface coating whose action is biocidal. The surface coating can be applied directly to the corresponding surfaces of the suction nozzle. In the context of the invention, however, it is also the case that a film with a biocidal effect is laminated on surfaces of the suction nozzle.
Eine weitere Ausgestaltung der erfindungsgemäßen Lehre sieht vor, dass die Saugdüse aus Kunststoff gefertigt ist, dem eine biozid wirkende Materialkomponente beigemischt ist. Im Rahmen der Erfindung liegt es auch, dass nur Teile der Saugdüse aus einem Kunststoff gefertigt sind, dem eine biozid wirkende Materialkomponente beigemischt ist, während die anderen Teile der Saugdüse aus Metall bestehen oder aus einem Kunststoff ohne Zusatz eines Biozids gefertigt sind.A further embodiment of the teaching according to the invention provides that the suction nozzle is made of plastic, to which a biocidal material component is admixed. In the context of the invention, it is also that only parts of the suction nozzle are made of a plastic, which is admixed with a biocidal material component, while the other parts of the suction nozzle made of metal or are made of a plastic without the addition of a biocide.
Die Oberflächenbeschichtung oder die bei der Herstellung der Saugdüse beigemischte biozid wirkende Materialkomponente basiert beispielsweise auf einem Hybridkomplex-Metall, welches vorzugsweise Silber, Silberverbindungen, Kupfer oder Kupferverbindungen beinhaltet. Sowohl Silber als auch Kupfer und auch einige ihrer Verbindungen weisen aufgrund der für Mikroorganismen vergleichsweise hohen Toxizität der Metallionen ein sehr bereits antimikrobielles Spektrum auf, wodurch eine Vielzahl gängiger Organismen auf diesem Material absterben wird.The surface coating or the biocidal material component admixed in the production of the suction nozzle is based, for example, on a hybrid complex metal which preferably contains silver, silver compounds, copper or copper compounds. Both silver and copper and also some of their compounds have a very much antimicrobial spectrum because of the relatively high toxicity of the metal ions to microorganisms, which will cause a large number of common organisms to die on this material.
Häufig besteht die Saugdüse aus mehreren Elementen, die ein ein- oder mehrteiliges Gehäuse, einen im Gehäuse angeordneten Saugkanal sowie unterseitig angeordnete Gleit- oder Stützelemente umfassen. Zumindest eines dieser Elemente ist erfindungsgemäß mit einer Ausrüstung ausgestattet, die das Ansiedeln von Mikroorganismen reduziert. Sofern alle Elemente der Düse mit der erfindungsgemäßen Ausrüstung ausgestattet sind, kann die Saugdüse umfassend vor einem Befall mit Mikroorganismen, insbesondere einem bakteriellem Befall geschützt werden. So kann auch verhindert werden, dass sich Bakterien oder Pilze in Hohlräumen und Ritzen der Düse ausbreiten.Frequently, the suction nozzle consists of several elements, which comprise a single-part or multi-part housing, a suction channel arranged in the housing, and sliding or supporting elements arranged on the underside. At least one of these elements is equipped according to the invention with equipment that reduces the colonization of microorganisms. If all elements of the nozzle are equipped with the equipment according to the invention, the suction nozzle can be comprehensively protected against infestation with microorganisms, in particular bacterial infestation. Thus, it can also be prevented that bacteria or fungi spread in cavities and cracks of the nozzle.
