Description

Die Erfindung bezieht sich auf einen Staubsauger mit einem Staubbeutelraum und axial hinter diesem angeordneten Gebläseaggregat, bei dem dem Gebläseaggregat ein Filter nachgeordnet und die Ausblasluft einen zwischen dem Staubbeutelraum und dem Boden des Staubsaugergehäuses vorgesehenen Hohlraum durchströmt.The invention relates to a vacuum cleaner with a dust bag compartment and a blower unit arranged axially behind it, in which a fan is arranged downstream of the blower unit and the blow-out air flows through a cavity provided between the dust bag compartment and the bottom of the vacuum cleaner housing.

Ein solcher Staubsauger ist durch die DE-AS 16 28 702 bekannt. Bei diesem Staubsauger dient der unter dem Staubbeutelraum vorgesehene Hohlraum zur Aufnahme des Saugschlauches. Dieser Hohlraum wird während des Betriebes des Staubsaugers zum Ausblasen der vom Gebläseaggregat angesaugten Luft herangezogen. Infolge des langen Weges und der großen Fläche wird die Strömungsgeschwindigkeit vermindert und damit das Geräusch reduziert.Such a vacuum cleaner is known from DE-AS 16 28 702. In this vacuum cleaner, the cavity provided under the dust bag compartment serves to receive the suction hose. This cavity is used during the operation of the vacuum cleaner to blow out the air sucked in by the blower unit. Due to the long way and the large area, the flow velocity is reduced and thus the noise is reduced.

Der Erfindung liegt die Aufgabe zugrunde, die Geräuschdämpfung noch weiter zu verbessern.The invention has for its object to further improve noise reduction.

Dies gelingt nach der Erfindung dadurch, daß im Boden des Staubsaugergehäuses nach unten gerichtete Ausblasöffnungen vorgesehen sind. Durch die im Boden vorgesehenen Ausblasöffnungen wird die ausströmende Luft gegen die abzusaugende Fläche gerichtet, wodurch eine wesentliche Schalldämpfung eintritt, insbesondere, wenn die abzusaugende Fläche noch aus schallschluckendem Material (Teppichen) besteht.This is achieved according to the invention in that downward discharge openings are provided in the bottom of the vacuum cleaner housing. The outlet openings provided in the floor direct the outflowing air against the surface to be extracted, which results in substantial sound absorption, especially if the surface to be extracted still consists of sound-absorbing material (carpets).

Eine weitere Verbesserung der Schalldämpfung gelingt dadurch, daß der ganze Boden mit Ausblasöffnungen versehen ist. Hierdurch steht der ausströmenden Luft eine große Fläche zur Verfügung, so daß die Ausströmgeschwindigkeit stark vermindert wird, wodurch sich eine entsprechende Reduzierung der Geräusche ergibt. Eine gleichmäßige Verteilung der Ausblasluft über der gesamten Bodenfläche wird dadurch erzielt, daß das Filter auf der Innenseite des Bodens unmittelbar über den Ausblasöffnungen angeordnet ist. Die gleichmäßige Verteilung führt außerdem zu einer geringeren Ausströmgeschwindigkeit, so daß die ausströmende Luft durch das Filter noch besser gefiltert wird und der austretende Luftstrom infolge der geringen Strömungsgeschwindigkeit keine Schmutzpartikel von der abzusaugenden Fläche aufwirbelt.A further improvement in sound absorption is achieved by providing the entire floor with blow-out openings. As a result, the outflowing air has a large area available, so that the outflow speed is greatly reduced, which results in a corresponding reduction in noise. A uniform distribution of the blow-out air over the entire floor area is achieved in that the filter is arranged on the inside of the floor directly above the blow-out openings. The even distribution also leads to a lower outflow speed, so that the outflowing air is filtered even better by the filter and the escaping airflow does not whirl up dirt particles from the surface to be extracted due to the low flow rate.

Dadurch, daß das Filter herausnehmbar ist und aus waschbarem Material besteht, kann dieses leicht gereinigt werden, so daß stets eine gute Filterwirkung gegeben ist.Because the filter is removable and made of washable material, it can be easily cleaned, so that there is always a good filter effect.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispieles wird der Anmeldungsgegenstand nachfolgend näher beschrieben.The subject of the application is described in more detail below using an exemplary embodiment shown in the drawing.

In einem Staubsaugergehäuse 1 ist ein Staubbeutelraum 2 vorgesehen, in dem ein Staubbeutel 3 auf einen Einlaßstutzen 4 aufgesteckt ist. Axial hinter dem Staubbeutelraum 2 ist in einem Gebläseraum 6 ein Gebläseaggregat 5 angeordnet, welches den zum Saugen notwendigen Saugluftstrom erzeugt. Unterhalb des Staubbeutelraumes 2 und des Gebläseraumes 6 ist ferner ein Hohlraum 7 ausgebildet. In diesem Hohlraum 7 ist ein Zwischenboden 8 eingefügt, der mit Leitrippen 9 versehen ist. In den Raum zwischen dem Zwischenboden 8 und dem Boden 10 des Staubsaugergehäuses 1 ist ein Filter 11 eingefügt. Der Boden 10 des Staubsaugergehäuses 1 ist mit Ausblasöffnungen versehen.In a vacuum cleaner housing 1, a dust bag space 2 is provided, in which a dust bag 3 is attached to an inlet nozzle 4. A blower unit 5, which generates the suction air flow necessary for suction, is arranged axially behind the dust bag chamber 2 in a blower chamber 6. A cavity 7 is also formed below the dust bag space 2 and the blower space 6. In this cavity 7, an intermediate floor 8 is inserted, which is provided with guide ribs 9. A filter 11 is inserted into the space between the intermediate floor 8 and the floor 10 of the vacuum cleaner housing 1. The bottom 10 of the vacuum cleaner housing 1 is provided with blow-out openings.

Die von dem Gebläseaggregat 5 ausgestoßene Ausblasluft durchströmt den Gebläseraum 6 und gelangt von diesem in den Hohlraum 7. In dem Hohlraum 7 wird die Ausblasluft durch die Leitrippen 9 über das Filter hinweggeleitet und durchdringt dieses und tritt an den im Boden des Staubsaugers 1 vorgesehenen Ausblasöffnungen nach unten aus dem Staubsaugergehäuse 1 heraus. Dadurch, daß die Ausblasluft gegen die abzusaugende Fläche gelenkt wird, die in der Regel noch aus einem schallschluckenden Material (Teppich) besteht, wird eine sehr starke Geräuschdämpfung erreicht. Da der ganze Boden des Staubsaugergehäuses 1 mit Ausblasöffnungen versehen ist, steht für den Luftaustritt ein relativ großer Querschnitt zur Verfügung, so daß die Austrittsgeschwindigkeit der Ausblasluft stark vermindert wird. Hierdurch ergibt sich eine weitere Geräuschdämpfung. Außerdem hat die geringe Austrittsgeschwindigkeit zur Folge, daß von der abzusaugenden Fläche keine Schmutzpartikel oder dergleichen aufgewirbelt werden.The blow-out air expelled by the blower unit 5 flows through the blow-out space 6 and from there into the cavity 7. In the cavity 7, the blow-out air is guided through the guide ribs 9 over the filter and penetrates it and occurs at the blow-out openings provided in the bottom of the vacuum cleaner 1 out of the vacuum cleaner housing 1 below. The fact that the blow-out air is directed against the surface to be extracted, which usually still consists of a sound-absorbing material (carpet), results in a very strong noise reduction. Since the entire bottom of the vacuum cleaner housing 1 is provided with blow-out openings, a relatively large cross section is available for the air outlet, so that the outlet speed of the blow-out air is greatly reduced. This results in further noise reduction. In addition, the low exit velocity means that no dirt particles or the like are whirled up by the surface to be suctioned off.

Das Filter 11 kann leicht aus dem Staubsauger herausgenommen und gereinigt werden. Damit ist stets eine gute Filterwirkung gewährleistet, die außerdem auch durch die geringe Austrittsgeschwindigkeit der Ausblasluft noch begünstigt wird. Infolge der geringen Austrittsgeschwindigkeit der Ausblasluft können durch das Filter auch Bakterien absorbiert werden. Darüber hinaus kann das Filter mit antibakteriellen Mitteln getränkt werden, so daß die absorbierten Bakterien abgetötet werden.The filter 11 can be easily removed from the vacuum cleaner and cleaned. So there is always one good filter effect guaranteed, which is also further favored by the low outlet speed of the blow-out air. Due to the low outlet velocity of the blow-out air, bacteria can also be absorbed by the filter. In addition, the filter can be soaked with antibacterial agents, so that the absorbed bacteria are killed.
