Abstract

The vacuum cleaner is provided with an air-tight dust bag (8) which is tightly clamped in between the two parts (7, 7a) of the vacuum cleaner housing so that the base of the bag (8) is drawn in through suction openings (13) in the lower part (7a) of the housing where it is held taut in the open position in order to collect the dust. In this way, after the dust bag has been sucked in empty through the suction openings, the weight of the accumulating dust keeps the bag taut. Since the suction current is not directed through the dust bag the latter can be made of an air-impermeable material such as the conventional plastic bags.

Description

Staubbeutelanordnung für Staubabscheider von Staubsaugern. Dust bag arrangement for dust separators of vacuum cleaners.

Die Erfindung betrifft eine Stausbeutelanordnung für Staubabscheider von Staubsaugern, bei welcher an eier Auflagefläche des Staubbeutels an Staubsaugergehäuse Saugöffnunoen vorgesehen sind, so daß der Staubbeutel stets glatt am Staubsaugergehäuse anliegt.The invention relates to a dunnage bag arrangement for dust separators of vacuum cleaners, in which on a support surface of the dust bag on the vacuum cleaner housing Saugöffnunoen are provided so that the dust bag is always smooth on the vacuum cleaner housing is present.

Eine derartige Staubbeutelanordnung ist bereits aus der US-PS 2 331 332 bekannt. Bei dieser bekannten Ausführungsform ist die sante Mantelfläche des Staubsaugergehäuses als Käfig ausgebildet, um den Staubbeute; anzusaugen, während die Grundfläche des Staubeutels an einer in Saugrichtung enden Filtermatte aufliegt.Such a dust bag arrangement is already known from US Pat. No. 2,331 332 known. In this known embodiment, the sante lateral surface of the Vacuum cleaner housing designed as a cage to the dust; suck in while the base of the storage bag rests on a filter mat that ends in the suction direction.

Durch din Aufbau bedingt, nimmt die Saugleistung mit der Füllhöhe im Staubbeutel ab. Außerdem ist die Ausbildung der Gehäusemantelfläche als Käfig komplizert.Due to the structure, the suction power increases with the filling level in the dust bag. In addition, the casing surface is designed as a cage complicated.

besaib hat sich die Erfindung die Aufgabe gestellt, diese Nachteile zu vermeiden und eine einfache Staubbeutelanordnung für Staubaoocheider von Staubsaugern zur Verfugung zu stellen.In addition, the invention has set itself the task of addressing these disadvantages to avoid and a simple dust bag arrangement for the dust boilers of vacuum cleaners to provide.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der luftdichte Staubbeutel zwischen den beiden Gehäuseteilen dicht eingeklemmt ist und der Boden des Staubbeutels durch Saugöffnungen im Unterteil des Staubsaugergehäuses angesaugt wird, so daß der Staubbeutel im Inneren des Unterteiles des Gehäuses zur Aufnahme der Verunreinigungen straff offengehalten ist.This object is achieved in that the airtight Dust bag is clamped tightly between the two housing parts and the bottom the dust bag is sucked in through suction openings in the lower part of the vacuum cleaner housing is so that the dust bag inside the lower part of the housing for recording the impurities is kept tightly open.

Die mit der Erfindung erzielten Vorteile liegen insbesondere darin, da der Staubbeutel nur im ungebrauchten Zustand, d.h. während des ersten Saugvorganges durch die @augöffnungen an den Unterteil des Staubsaugergehäuses angesaugt zu werden braucht und das danach das Eigengewicht der Staubbeutelfüllung die Straffung des Staubb@utels unterstütst. Ein weiterer Vorteil licgt darin, daß die Saugleistung elche durch die Saugöffnungen vermindert wird, nicht in dem Maße a@@immt, die @ei der bekannten A@@fünrungsform, bei der die gesamte @antelfläche des Gehäases mit Saugöffnungen versehen ist.The advantages achieved with the invention are, in particular, as the dust bag is only used when it is not in use, i.e. during the first vacuuming process to be sucked through the @ eye openings on the lower part of the vacuum cleaner housing needs and then the weight of the dust bag filling the tightening of the Staubb @ utels support. Another advantage is that the suction power which is diminished by the suction openings, not to the extent that a @@ immt, the @ei the well-known A @@ form of function, in which the entire surface of the housing with Suction openings is provided.

Ein erheblicher Vorteil der Erfindung liegt darin, daß der Staublieutel aus einem luftundurcnläsiten material, beispielsweise ein nundelsüblicher Plastikbeutel sein kann, da bei der erfindunrsgemäßen Anordnung der Saugstrom nicht durch den Staubbeutel hindurch rtchtet ist.A significant advantage of the invention is that the dust bag Made of an air-tight material, for example a standard plastic bag can be, because in the inventive arrangement of the suction flow is not through the Dust bag is right through.

Ein Au5f:ihrung5beispiel der Erfindung ist in der Zeichnung dorgestellt und wird im folgenden nä@er @eschrieben. Es zeigen Fig.1 eine schematische Darstellung eines Staubsaugers in Schnitt und Fig.2 eine Anordnung des Staubbeutels.An example of the invention is shown in the drawing and will be written in the following. 1 shows a schematic representation a vacuum cleaner in section and FIG. 2 shows an arrangement of the dust bag.

Fig.1 zeigt einen Schnitt durch eine Auffangvorrichtung 1, in der zei Gitter 4 und 5 schräg angeord@@t t sind. DasGitter 4 besitzt eine größere Maschenweite als das Gltter 5. Sehr grobe Verunreinigungen @erden durch das Gitter 4, feinere durch das Gitter 5 zurückgehalten. Kleinstpartikel, die durch das Gitter 5 durchfliegen, werden vom Papierband 6 zurückgchalten, welches auf einer außerhalb des Gehäuses 7 angeordneten Rolle lo bevorratet ist und das br die Austrittsöffnung 3 reicht. An dr Austrittsöffnung 3 montiert ist ein schematisch dargestellter Ventilator 11, der den Unterdruck erzeugt, der für das Ansaugen von Verunreinigungen durch die Eintrittsöffnung 2 notwendig ist und der sich durch den Saugkanal 9 bis zu den Saugöffnungen 13 im unterteil 7a des Staubsaugergehäuses fortpflanzt. Im Unterteil 7a des Gehäuses ist ein Staubbeutel 8 klemmend an dessen Rand befestigt. Damit der Staubbeutel 8 an der Wand des Gehäuseunterteies 7a straff gespannt ist, befindet sich am Geh äuseunterteil 7a ein Saugkanal 9 mit Öffnungeni3, der an den Unterdruck des Ventilators angeschlossen ist.Fig.1 shows a section through a collecting device 1 in which two grids 4 and 5 are at an angle. The grid 4 has a larger mesh size than the smoother 5. Very coarse soiling @ earths through the grille 4, finer retained by the grid 5. Small particles that fly through the grid 5, are switched back from the paper tape 6, which is on an outside of the housing 7 arranged roll lo is stored and the br the outlet opening 3 is enough. A schematically illustrated fan 11 is mounted on the outlet opening 3, which creates the negative pressure necessary for the suction of impurities through the Inlet opening 2 is necessary and which extends through the suction channel 9 to the suction openings 13 propagates in the lower part 7a of the vacuum cleaner housing. In the lower part 7a of the housing, a dust bag 8 is clamped attached to its edge. So that the Dust bag 8 is stretched taut on the wall of the housing base 7a a suction channel 9 with openings i3, which is connected to the negative pressure of the fan is connected.

Fig.2 zeigt eine tergrößerte Darstellung des Gehäuseunterteies 7a, welcher konusförmig in den Gehäuseoberteil 7 eingepaßt ist. Ein Saugkanal 9 in der wandung des Gehäuseoberteiles 7 setzt sich über den Konus 12 in das Gehäuseunterteil 7a fort und mündet in Saugöffnungen 13 im Boden des Gehäuseunterteiles 7a. Bei Inbetriebnahme des Staubsaugers ;ird der Boden des Staubbeutels 8 an den Boden des Gehäuseunterteiles 7a angesaugt, so daß er dort glatt aufliegt.2 shows an enlarged representation of the housing base 7a, which is fitted into the upper housing part 7 in a conical shape. A suction channel 9 in the wall of the upper housing part 7 is set over the cone 12 in the lower housing part 7a and opens into suction openings 13 in the bottom of the lower housing part 7a. When commissioning of the vacuum cleaner; ird the bottom of the dust bag 8 to the bottom of the lower part of the housing 7a sucked so that it rests there smoothly.

Gleichzeitig werden auch die Seitenflächen des Staubbeutels 8 straff gespannt.At the same time, the side surfaces of the dust bag 8 also become taut tense.
