Abstract
Description
Die Erfindung bezieht sich auf einen Ausblasfilter am Gehäuse von Bodenpflegegeräten, insbesondere Staubsauger, wobei über einen Saugkanal eine einem Motor vorgeschaltete Staubabscheideeinheit, wie eine Filtertüte und gegebenenfalls ein Motorschutzfilter angeordnet sind und die Ausblasluft über Luftaustritte im Gehäuse nach außen geführt wird.The invention relates to a blow-out filter on Housing of floor care devices, in particular Vacuum cleaner, one via a suction channel Motor upstream dust collection unit, such as a Filter bag and if necessary a motor protection filter are arranged and the exhaust air via air outlets is guided outside in the housing.
Bei Staubsaugern ist es üblich, die eingesaugte Luft nach einem Passieren der Schmutzaufnahme und der Filter über einen Ausblaskanal einer Mehrzahl benachbart zueinander angeordneter Gehäuseschlitze zuzuführen. Bei einem Austreten der Luft aus den Gehäuseschlitzen werden beträchtliche Strömungsgeschwindigkeiten erreicht. Durch die relativ starke Konzentration des Luftstromes werden Strömungsgeräusche erzeugt, darüber hinaus werden auch Schallanteile aus dem Motorbereich übertragen. With vacuum cleaners, it is common to take in the air after passing through the dirt pick-up and the filters adjacent to a plurality via a blow-out duct feed to each other arranged housing slots. at an escape of air from the housing slots become considerable flow velocities reached. Due to the relatively strong concentration of the Airflow, flow noise is generated, above In addition, there are also sound components from the engine area transfer.
Aus strömungstechnischen Gründen wird angestrebt, den Ausblaskanal und die Austrittsstelle im Bereich des Gehäuses des Staubsaugers möglichst groß zu gestalten, um hierdurch einen geringen Ausblaswiderstand hervorzurufen. Konträr zu diesen Anforderungen wird aber ebenfalls eine Verminderung von Schallemissionen gefordert, die durch einen relativ großen Strömungswiderstand erzielt werden könnte. Diese einander entgegenstehenden Forderungen konnten bislang nicht in zufriedenstellender Weise gelöst werden.For fluidic reasons, the aim is Blow-out duct and the exit point in the area of the To make the vacuum cleaner housing as large as possible, to have a low blowout resistance cause. Contrary to these requirements but also a reduction in noise emissions required by a relatively large Flow resistance could be achieved. This conflicting demands so far cannot be solved in a satisfactory manner.
Zur Verbesserung dieses Verhältnisses ist es nach der EP 0 706 774 B bekannt, den Austrittsquerschnitt über entsprechende abgedeckte Öffnungen in Form von Gehäuseschlitzen in den Seitenwandungen des Gehäuses als Schutzbandage zu erhöhen.To improve this ratio, it is after EP 0 706 774 B discloses the exit cross section corresponding covered openings in the form of Housing slots in the side walls of the housing to increase as a protective bandage.
Die Aufgabe der Erfindung ist es, auf einfach Weise die Ausströmfläche weiter zu vergrößern und geringe Strömungsgeschwindigkeiten zu ermöglichen und eine Schalldämmung zu gewährleisten.The object of the invention is to easily Outflow area further increase and small Allow flow velocities and a To ensure sound insulation.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß dadurch, daß mindestens ein großflächiger Gehäusebereich von einem Filtermaterial als Ausblasfilter abgedeckt bzw. ein Gehäuse schlauchartig von einem Filtermaterial als Ausblasfilter ganz oder teilweise umhüllt ist und die Ausblasluft in einen gebildeten Mantelraum zwischen Gehäuse und Filtermaterial zum Ausblasen zuführbar ist.This object is achieved according to the invention in that at least one large area Housing area from a filter material as Blow-out filter covered or a hose-like housing of a filter material as a blow-out filter entirely or is partially enveloped and the exhaust air into one formed jacket space between the housing and Filter material can be fed for blowing out.
Hierdurch wird auf mit einer einfachen technischen Maßnahme eine große Ausströmfläche gebildet, so daß lediglich geringe Strömungsgeschwindigkeiten im Ausströmbereich auftreten. Entsprechende Strömungsgeräusche sind somit sehr gering. Aufgrund der Ummantelung erfolgt darüber hinaus eine diffuse Abströmung der ausgeblasenen Luft, so daß in der Umgebung nahezu keine merkliche Strömungsintensität auftritt.This turns on with a simple technical Measure formed a large outflow area so that only low flow velocities in Outflow area occur. Appropriate Flow noise is therefore very low. Due to the Sheathing is also diffuse Outflow of the blown air, so that in the Nearly no noticeable flow intensity occurs.
Die geringe Strömungsgeschwindigkeit im Filterbereich hat darüber hinaus den Vorteil, daß ein hoher Abscheidegrad von Schwebstoffen erreicht wird. Durch das relativ große Filtervolumen wird dennoch eine sehr hohe Lebensdauer des Filters gewährleistet.The low flow rate in the filter area also has the advantage that a high The degree of separation of suspended matter is achieved. By the relatively large filter volume is still a very large one long filter life guaranteed.
Ferner wird durch das außenliegende Filtermaterial ein entsprechender vorteilhafter gestalterischer Effekt erzielt.Furthermore, due to the external filter material corresponding advantageous design effect achieved.
Eine einfache Ausbildung wird dadurch geschaffen, daß das schlauchartig ausgebildete Filtermaterial an beiden Stirnseiten über Befestigungselemente mit dem Gehäuse lösbar dichtend eingesetzt und in einem dem Motorraum zugewandten Bereich Durchtritte ausgebildet sind.A simple training is created in that the tubular filter material on both End faces with fasteners to the housing releasably used sealing and in the engine compartment facing area passages are formed.
Damit sind auch unterschiedliche ästhetische Gestaltungen, wie farbliche und mustermäßige Variationen mit einem identischen Grundgerät gewährleistet.So there are also different aesthetic Designs such as color and pattern Variations with an identical basic device guaranteed.
Eine vorteilhafte Ausgestaltung besteht darin, daß das Filtermaterial in Mikrofilterqualität ausgebildet ist.An advantageous embodiment is that Filter material is designed in microfilter quality.
Um einen Schutz zur Vermeidung von Beschädigungen am Gerät und ortsfesten Einrichtungsgegenständen bei Reinigungsarbeiten zu verbessern, ist vorgesehen, daß das außenliegende Filtermaterial durch einen elastischen Tragkörper gehalten ist. To provide protection to avoid damage to the Device and fixed furnishings To improve cleaning work, it is provided that the external filter material through a elastic support body is held.
Alternativ ist vorgesehen, daß das außenliegende Filtermaterial durch einen luftdurchlässigen elastischen Tragkörper gebildet ist.Alternatively, it is provided that the outside Filter material through an air permeable elastic support body is formed.
In der Zeichnung ist ein Ausführungsbeispiel eines Handstaubsaugers schematisch im Schnitt dargestellt.In the drawing is an embodiment of a Manual vacuum cleaner shown schematically in section.
Bei dem dargestellten Staubsauger ist ein Gehäuse 1
angeordnet, das mit einem Saugkanal 2 als Schlauch
versehen ist und im Gehäuse 1 in eine zu ladende
Filtertüte 3 mündet sowie einen unterhalb der
Filtertüte 3 angeordneten Motor 4 in einem Motorraum 5
aufweist. In bekannter Weise ist dem Motor 4 ein
Motorschutzfilter 6 vorgeschaltet.In the vacuum cleaner shown, there is a
Das Gehäuse 1 ist in seinem zylindrischen Bereich
schlauchartig von einem Filtermaterial 7 umhüllt. Das
Filtermaterial 7 ist über Befestigungselemente 8, 9 am
Gehäuse 1 lösbar verbunden und gegenüber dem
Außenbereich abgedichtet. Hierdurch wird zwischen dem
Gehäuse 1 und dem Filtermaterial 7 ein Mantelraum 11
gebildet, der über Durchtritte 10 mit dem Motorraum 5
verbunden ist und die Ausblasluft über das
Filtermaterial 7 großflächig austritt.The
