Abstract

The invention relates to a wet-dry vacuum cleaner, in whose housing a waste collection chamber is constructed which accommodates a disposable filter bag, in which vacuum cleaner the filter bag (4) has a bag part which consists of impermeable material and is retained by a carrier part (8) which can be placed on a circumferential edge (13) provided on the wall of the waste collection chamber (3), on which carrier part (8) a filter part is arranged in the region of a passage opening (12) for the air flow (26) taken in by the fan of the wet-dry vacuum cleaner and an inlet opening (15) is constructed which opens out into the bag part and is connected in terms of flow to an intake opening (17) provided on a lid part (14) which can be fitted onto the housing. In a wet-dry vacuum cleaner of this type, hygienic handling is possible due to the fact that the bag part (9) is attached by its opening edge (5) in the circumferential region of the carrier part (8), passing around the latter, and the filter part (10) is detachably connected to said carrier part (8), spanning the passage openings (12) thereof. <IMAGE>

Description

Die Erfindung betrifft einen Schmutzsauger gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a vacuum cleaner according to the preamble of claim 1.

Ein solcher für das Aufsaugen von trockenem, feuchtem oder nassem Schmutz geeigneter Schmutzsauger ist durch die DE-C-39 00 083 bekannt. Bei diesem Staubsauger ist ein aus undurchlässigem Material bestehender Foliensack mi seinem Öffnungsrand zwischen einem an der Wand des Schmutzsammelraumes vorgesehenen Umlaufrand und einem auf diesen Umlaufrand auflegbaren Tragteil eingeklemmt gehalten. Das Tragteil selbst ist als stabiles Formteil ausgebildet, an dem eine entsprechende Halterung für einen austauschbaren, rohrförmigen Filterteil vorgesehen ist.Such a vacuum cleaner suitable for vacuuming dry, moist or wet dirt is known from DE-C-39 00 083. In this vacuum cleaner, a film bag consisting of impermeable material is held clamped with its opening edge between a peripheral edge provided on the wall of the dirt collecting space and a supporting part which can be placed on this peripheral edge. The support part itself is designed as a stable molded part, on which a corresponding holder for an exchangeable, tubular filter part is provided.

Beim Entsorgen eines mit Schmutz gefüllten Foliensackes muß bei diesem Schmutzsauger das Tragteil abgenommen werden, so daß der Foliensack vollständig offen ist. Zwar ist im Bereich des Öffnungsrandes eine Ringschnur vorgesehen, mit der der Foliensack zusammengeschnürt werden kann, jedoch ist das Zusammenschnüren erst nach dem Entfernen des Tragteils möglich. Beim Zusammenschnüren selbst kann Schmutz aus dem Foliensack entweichen. Auch der Austausch des Filterteiles ist relativ unhygienisch, da der verschmutzte Filterteil erfaßt und von dem Tragteil abgenommen und danach entsorgt werden muß.When disposing of a foil bag filled with dirt, the supporting part of this vacuum cleaner must be removed so that the foil bag is completely open. A ring cord is provided in the area of the opening edge with which the film bag can be tied together, but tying is only possible after the support part has been removed. When tied together, dirt can escape from the film bag. The replacement of the filter part is also relatively unsanitary, since the dirty filter part must be grasped and removed from the support part and then disposed of.

Der Erfindung liegt die Aufgabe zugrunde, einen Schmutzsauger der gattungsgemäßen Art so weiterzubilden, daß der Wechsel eines gefüllten Filterbeutels auf hygienisch einwandfreie Art möglich ist.The invention has for its object to develop a vacuum cleaner of the generic type so that the change of a filled filter bag is possible in a hygienically perfect manner.

Die Lösung der gestellten Aufgabe gelingt durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale. Bei einer solchen Gestaltung des Schmutzsaugers wird der Schmutz von oben in den Filterbeutel eingesaugt, so daß sich dieser insbesondere, wenn er feucht oder flüssig ist, im unteren Bereich des Filterbeutels ablagert. Das Filterteil bleibt somit bei jeder Schmutzart wirksam. Da das Tragteil mit dem Beutel und Filterteil fest verbunden ist, bleibt auch bei einem Wechsel des Filterbeutels dieser von dem Tragteil überdeckt, so daß ein Entweichen von Schmutz verhindert ist, insbesondere dann, wenn der Einlaßöffnung des Tragteils eine Verschlußklappe zugeordnet ist, durch die die Einlaßöffnung beim Filterwechsel vollständig verschließbar ist. Durch die obenliegende relativ kleine Einlaßöffnung wird ein Entweichen von Schmutz oder Flüssigkeit ohnehin schon weitgehend ausgeschlossen.The problem is solved by the features specified in the characterizing part of claim 1. With such a design of the dirt suction device, the dirt is sucked into the filter bag from above, so that it is deposited in the lower region of the filter bag, particularly when it is moist or liquid. The filter part therefore remains effective for all types of dirt. Since the support part is firmly connected to the bag and filter part, this remains covered by the support part even when the filter bag is changed, so that escape of dirt is prevented, in particular if the inlet opening of the support part is assigned a closure flap through which the Inlet opening when changing the filter is completely closable. The relatively small inlet opening at the top largely prevents any escape of dirt or liquid anyway.

Vorteilhaft ist es, wenn das Filterteil des Filterbeutels feuchtigkeitsfest ausgebildet ist. Bei einer doppellagigen Ausbildung des Tragteils ergibt sich neben der Erhöhung der Festigkeit des Tragteiles noch der Vorteil der einfachen Befestigungsmöglichkeit des Filter- und Beutelteils zwischen den beiden Lagen des Tragteils. Durch die Nachschaltung eines Zusatzfilters gemäß Anspruch 4 wird die Reinigungswirkung verbessert.It is advantageous if the filter part of the filter bag is designed to be moisture-proof. In the case of a double-layer design of the support part, in addition to increasing the strength of the support part, there is also the advantage of the simple fastening possibility of the filter and bag part between the two layers of the support part. By adding an additional filter according to claim 4, the cleaning effect is improved.

Beim Aufsaugen von Flüssigkeit wird ein Überlaufen des Filterbeutels durch die im Anspruch 5 beschriebenen Maßnahmen verhindert.When absorbing liquid, overflow of the filter bag is prevented by the measures described in claim 5.

Eine das Abnehmen des Deckelteils erleichternde Gewichtsminderung wird bei einem gemäß den Merkmalen des Anspruchs 6 ausgestalteten Schmutzsauger erreicht.A weight reduction facilitating the removal of the cover part is achieved in a dirt vacuum cleaner designed according to the features of claim 6.

a plan view of the support part of a filter bag.

Mit 1 ist das auf einem fahrbaren Traggestell 2 montierte Gehäuse eines Schmutzsaugers bezeichnet. In dem Gehäuse 1 ist ein Schmutzsammelraum 3 ausgebildet, in den ein Filterbeutel 4 eingesetzt ist. Der Filterbeutel 4 besteht aus einem mit seinem Öffnungsrand 5 zwischen zwei Papplagen 6 und 7 eines steifen, plattenförmigen Tragteiles 8 befestigten Beutelteil 9 und einem Filterteil 10, das mit seinem Umfangsrand 11 am Umfang einer in dem Tragteil 8 ausgebildeten Durchlaßöffnung 12 ebenfalls zwischen den Papplagen 6 und 7 befestigt ist. Der Beutelteil 9 besteht aus undurchlässigem Material, z.B. aus Kunststoffolie.1 with the housing of a vacuum cleaner mounted on a mobile support frame 2 is designated. A dirt collecting space 3 is formed in the housing 1, into which a filter bag 4 is inserted. The filter bag 4 consists of a bag part 9 fastened with its opening edge 5 between two cardboard layers 6 and 7 of a rigid, plate-shaped support part 8 and a filter part 10, which with its peripheral edge 11 on the circumference of a passage opening 12 formed in the support part 8 also between the cardboard layers 6 and 7 is attached. The bag part 9 is made of impermeable material, e.g. made of plastic film.

Das Tragteil 8 liegt auf einem an der Innenseite des Schmutzsammelraumes 3 angeformten Umlaufrand 13 auf und wird durch einen den Schmutzsammelraum 3 überdeckenden Deckelteil 14, zwischen diesem und dem Umlaufrand 13 eingeklemmt gehalten. Am Tragteil 8 ist ferner eine Einlaßöffnung 15 vorgesehen, die über ein im Deckelteil angeordnetes Rohrteil 16 mit der am Deckelteil 14 ausgebildeten Ansaugöffnung 17 des Schmutzsaugers in Saugverbindung steht.The supporting part 8 rests on a peripheral edge 13 formed on the inside of the dirt collecting space 3 and is held clamped between the latter and the peripheral edge 13 by a cover part 14 covering the dirt collecting space 3. On the support part 8 there is also an inlet opening 15 which is in suction connection via a pipe part 16 arranged in the cover part with the suction opening 17 of the vacuum cleaner formed on the cover part 14.

Mit dem Deckelteil 14 ist ferner ein Schwimmerventil 18 verbunden. Dieses besteht aus einem in einem Käfig 19 angeordneten Schwimmer 20 und einer Ventilauslaßöffnung 21. Strömungsmäßig ist hinter der Ventilauslaßöffnung 21 noch ein Zusatzfilter 22 im Deckelteil 14 angebracht.A float valve 18 is also connected to the cover part 14. This consists of a float 20 arranged in a cage 19 and a valve outlet opening 21. In terms of flow, an additional filter 22 is also installed in the cover part 14 behind the valve outlet opening 21.

Der Innenraum 23 des Deckelteils 14 steht über einen im Gehäuse 1 des Schmutzsaugers ausgeformten Saugkanal 24 mit dem Gebläse 25 des Schmutzsaugers in Saugverbindung. Der von dem Gebläse 25 erzeugte, durch Pfeile 26 angedeutete Saugluftstrom tritt über die Ansaugöffnung 17, das Rohrteil 16 und die Einlaßöffnung 15 in den Beutelteil 9 des Filterbeutels 8 ein. Infolge der Schwerkraft lagert sich der in dem Saugluftstrom enthaltene Schmutz bereits weitgehend am Boden des Beutelteils 9 ab, insbesondere dann, wenn es sich bei dem Schmutz um nasses oder gar flüssiges Sauggut handelt. Bei dem anschließenden Durchtritt des Saugluftstromes durch das Filterteil 10 werden die nach dem Durchströmen des Beutelteils noch im Saugluftstrom verbliebenen Schmutzteile weitgehend zurückgehalten. Eine weitere Filterung erfolgt dann nochmals durch das Zusatzfilter 22, das gegenüber dem Filterteil 10 feinporiger ausgebildet sein kann.The interior 23 of the cover part 14 is in suction connection with the blower 25 of the vacuum cleaner via a suction channel 24 formed in the housing 1 of the vacuum cleaner. The suction air flow generated by the fan 25, indicated by arrows 26, passes through the suction opening 17, the pipe part 16 and the inlet opening 15 into the bag part 9 of the filter bag 8. As a result of gravity, the dirt contained in the suction air flow is already largely deposited on the bottom of the bag part 9, in particular when the dirt is wet or even liquid suction material. During the subsequent passage of the suction air flow through the filter part 10, the dirt parts remaining in the suction air flow after flowing through the bag part are largely retained. A further filtering is then carried out again by the additional filter 22, which can be made more fine-pored than the filter part 10.

Wird mit dem Schmutzsauger Flüssigkeit aufgesaugt, dann wird ein Überlaufen des Filterbeutels 4 durch das Schwimmerventil 18 verhindert. Sobald der Flüssigkeitsstand das Schwimmerventil 18 erreicht, wird bei einem weiteren Ansteigen des Flüssigkeitsspiegels der Schwimmer 20 angehoben, bis er gegen die Ventilauslaßöffnung 21 stößt und diese verschließt. Damit wird der Saugluftstrom unterbrochen und keine weitere Flüssigkeit mehr angesaugt.If liquid is sucked up with the dirt suction device, then overflow of the filter bag 4 by the float valve 18 is prevented. As soon as the liquid level reaches the float valve 18, when the liquid level rises further, the float 20 is raised until it abuts the valve outlet opening 21 and closes it. This interrupts the suction air flow and no more liquid is drawn in.

Beim Austausch eines gefüllten Filterbeutels 4 wird dieser an seinem Tragteil 8 erfaßt und aus dem Schmutzsammelraum 3 herausgehoben. Da sich die Einlaßöffnung 15 in dem Tragteil 8 befindet, besteht keine Gefahr, daß Schmutz aus dem Filterbeutel 4 austritt. Infolge der Undurchlässigkeit des Beutelteils 9 wird außerdem eine Verschmutzung des Schmutzsammelraumes 3 vermieden.When a filled filter bag 4 is exchanged, it is gripped on its supporting part 8 and lifted out of the dirt collecting space 3. Since the inlet opening 15 is located in the support part 8, there is no danger that dirt will escape from the filter bag 4. As a result of the impermeability of the bag part 9, contamination of the dirt collecting space 3 is also avoided.

Ein Zusammenziehen des Beutelteils 9 infolge des beim Saugen erzeugten Unterdruckes kann auf einfache Weise dadurch verhindert werden, daß im Tragteil 8 Durchbrüche 27 vorgesehen sind, die außerhalb des am Tragteil 8 befestigten Beutelteils 9 in den Schmutzraum 3 münden. Über diese Durchbrüche wird der im Innenraum 23 des Deckelteils herrschende Druck im Schmutzsammelraum 3 wirksam. Infolge des durch das Filterteil 10 bedingten Druckabfalles ist der Druck im Schmutzsammelraum 3 niedriger als der Druck im Filterbeutel 4. Damit wird der Beutelteil 9 des Filterbeutels 4 entsprechend aufgebläht und füllt den Schmutzsammelraum 3 optimal aus.A contraction of the bag part 9 as a result of the negative pressure generated during suction can be prevented in a simple manner by providing openings 27 in the support part 8 which open outside the bag part 9 fastened to the support part 8 into the dirt space 3. The pressure prevailing in the interior 23 of the cover part in the dirt collecting space 3 is effective via these openings. As a result of that caused by the filter part 10 Pressure drop, the pressure in the dirt collecting chamber 3 is lower than the pressure in the filter bag 4. The bag part 9 of the filter bag 4 is accordingly inflated and optimally fills the dirt collecting chamber 3.
