Description

Die Erfindung betrifft einen Schmutzsauger mit einer Schwenkklappe nach dem Oberbegriff des Patentanspruches 1.The invention relates to a vacuum cleaner with a pivoting flap according to the preamble of claim 1.

Bei einem Bodenreinigungsgerät der Firma Nilfisk ALTO vom Typs Floortec 560B oder des Typs SW700 ist es bekannt, an der Rückseite des Gehäuses eine abnehmbare Klappe anzuordnen, hinter der ein schräg geneigter Faltenfilter angeordnet ist, welcher vom Abreinigungsluftstrom beströmt wird. Die Anordnung eines schräg angeordneten Faltenfilters hat den Vorteil, dass der Abreinigungsluftstrom schräg auf das Faltenfilter einwirkt und dass bei zunehmender Zusetzung des Faltenfilters zunächst die in den Schmutzsaugerbehälter am nächsten hineinragenden Teile des Faltenfilters sich vollsetzen und die oberen Teile des Faltenfilters, die von dem Schmutzsaugerbehälter am weitesten entfernt sind, sich am langsamsten zusetzen.In a floor cleaning device of the company Nilfisk ALTO of the type Floortec 560B or SW700 type, it is known to arrange a removable flap on the back of the housing, behind which an obliquely inclined pleated filter is arranged, which is flowed through by Abreinigungsluftstrom. The arrangement of an obliquely arranged pleated filter has the advantage that the Abreinigungsluftstrom obliquely acts on the pleated filter and that with increasing clogging of the pleated filter initially in the dirt suction container next protruding parts of the pleated filter to complete and the upper parts of the pleated filter, the dirt from the vacuum tank on farthest away, slowest.

Damit wird die Standzeit des schräg oberhalb des Schmutzsaugerbehälters angeordneten Faltenfilters verbessert.This improves the service life of the folded filter arranged diagonally above the dirt suction container.

Die Anordnung eines solchen schräg gegenüber der Bodenfläche des Schmutzsaugerbehälters angeordneten Faltenfilters hat sich bewährt. Nachteil der Anordnung ist jedoch, dass er schwer zugänglich ist, weil zum Auswechseln des Faltenfilters oder eines gleichwertigen Vlieses sich die Bedienungsperson auf den Boden niederknien muss, um den Faltenfilter aus dem Gehäuse des Schmutzsaugers herauszulösen.The arrangement of such a diagonally opposite the bottom surface of the Schmutzsaugerbehälters arranged fold filter has proven itself. Disadvantage of the arrangement, however, is that it is difficult to access, because to replace the pleated filter or equivalent fleece, the operator must kneel down on the ground to release the pleated filter from the body of the vacuum cleaner.

Dazu muss eventuell auch die Abreinigungsvorrichtung für das Filter vorher entfernt werden, was mit hohem Arbeitsaufwand verbunden ist.For this purpose, possibly the cleaning device for the filter must be removed beforehand, which is associated with high workload.

Die US 2 409 078 A offenbart einen Schmutzsauger mit einem Gehäuse, welches aus einem Unterteil mit einem Schmutzbehälter und einem Oberteil besteht, wobei im Gehäuse mindestens ein Filter angeordnet ist, welcher von einem Absaugluftstrom durchströmbar ist. Das Oberteil des Gehäuses ist als Schwenkgehäuse ausgebildet. Der Filter ist im Unterteil des Gehäuses angeordnet.The US 2 409 078 A discloses a vacuum cleaner with a housing, which consists of a lower part with a dirt container and a top, wherein in the housing at least one filter is arranged, which is traversed by a suction air flow. The upper part of the housing is designed as a swivel housing. The filter is arranged in the lower part of the housing.

Der Erfindung liegt die Aufgabe zugrunde, einen Schmutzsauger mit schräg geneigten Filtern allgemeiner Art so weiterzubilden, dass ein einfaches Auswechseln des Filters ohne hohen Arbeitsaufwand gegeben ist, und dass auch auf einfache Weise unterschiedliche Abreinigungsvorrichtungen verwendet werden können.The invention has the object of developing a vacuum cleaner with obliquely inclined filters general type so that a simple replacement of the filter is given without high workload, and that in a simple way different cleaning devices can be used.

Zur Lösung der gestellten Aufgabe ist die Erfindung durch die technische Lehre des Anspruches 1 gekennzeichnet.To solve the problem, the invention is characterized by the technical teaching of claim 1.

Wesentliches Merkmal der Erfindung ist, dass der schräg geneigte Filter, welcher bevorzugt als Flachfilter ausgebildet ist, in einer schrägen Trennebene eines Schwenkgehäuses aufgenommen ist. Das Schwenkgehäuse ist hierbei im Wesentlichen an einer horizontalen Achse am Oberteil des Schmutzsaugers angeordnet ist, sodass beim Verschwenken des Gehäuses damit gleichzeitig auch der eine oder mehrere Flachfilter zugänglich werden, ohne dass am Gehäuse des Staubsaugers Auswechselungsarbeiten vorgenommen werden müssen.An essential feature of the invention is that the obliquely inclined filter, which is preferably designed as a flat filter, is accommodated in an oblique parting plane of a pivot housing. The swivel housing is in this case arranged substantially on a horizontal axis on the upper part of the dirty vacuum, so that at the same time the one or more flat filters are accessible during pivoting of the housing without the replacement of the housing of the vacuum cleaner must be made.

Der Wert der Erfindung liegt demnach darin, dass der Filter nicht mehr in einem gehäusefesten Rahmen untergebracht ist, sondern vielmehr in einer. Die Schwenkklappe ist bevorzugt an einer horizontalen Achse an der Oberseite oder Unterseite des Schmutzsaugers angeordnet, welche eine schräge Trennebene ausbildet, in welcher der eine oder die mehreren Flachfilter angeordnet sind.The value of the invention is therefore that the filter is no longer housed in a housing-fixed frame, but rather in a. The pivoting flap is preferably arranged on a horizontal axis at the top or bottom of the vacuum cleaner, which forms an oblique parting plane, in which the one or more flat filters are arranged.

Durch einfaches Hochschwenken oder Herabschwenken des Schwenkgehäuses werden somit, die an der Innenseite des Schwenkgehäuses im Bereich einer Trennwand angeordneten Flachfilter, zugänglich und können leicht ausgewechselt werden.By simply pivoting or swiveling down the swivel housing, the flat filters arranged on the inside of the swivel housing in the region of a partition wall are thus accessible and can be easily exchanged.

Weiterer Vorteil der Erfindung liegt darin, dass es nun erstmals möglich ist, im Innenraum der Schwenkklappe auch zugeordneten Abreinigungsvorrichtungen anzuordnen, was bisher beim Stand der Technik nicht möglich war.Another advantage of the invention is that it is now possible for the first time to arrange in the interior of the pivoting flap also associated cleaning devices, which was previously not possible in the prior art.

Eine solche Abreinigungsvorrichtung kann zum Beispiel als 3-Wegeventil ausgebildet sein, wie es Gegenstand der DE 101 01 219 B4 ist.Such a cleaning device may be formed, for example, as a 3-way valve, as it is the subject of DE 101 01 219 B4 is.

Eine andere Abreinigungsvorrichtung ist beispielsweise mit dem Gegenstand der DE 41 38 223 C1 bekannt geworden, die in gleicher Weise in dem Innenraum des erfindungsgemäßen Schwenkgehäuses eingebaut werden kann.Another cleaning device is, for example, with the subject of DE 41 38 223 C1 become known, which can be installed in the same way in the interior of the pivot housing according to the invention.

Die Verwendung elektrisch umschaltbarer 3-Wegeventile ist beispielsweise mit dem Gegenstand der EP 1 997 415 B1 gezeigt. Eine solche Anordnung kann ebenfalls auf einfache Weise im Innenraum des Schwenkgehäuses eingebaut werden.The use of electrically reversible 3-way valves is, for example, with the subject of EP 1 997 415 B1 shown. Such an arrangement can also be installed in a simple manner in the interior of the swivel housing.

Damit besteht der Vorteil, dass beim Öffnen des Schwenkgehäuses nicht nur die am Schwenkgehäuse angeordneten ein oder mehreren Flachfilter leicht zugänglich sind, sondern auch die den Flachfiltern zugeordneten Abreinigungsvorrichtungen. Dies war bisher im Stand der Technik nicht bekannt.This has the advantage that not only the arranged on the pivot housing one or more flat filters are easily accessible when opening the pivot housing, but also the flat filters associated cleaning devices. This was previously unknown in the prior art.

Der hier verwendete Begriff "Flachfilter" ist nicht einschränkend zu verstehen. Statt eines Flachfilters können beliebige Filterarten verwendet werden, wie zum Beispiel Filtervliese, Rundfilter, Zick-Zack-Filter, Faltenfilter beliebiger Art oder dergleichen mehr. Es kommt nur darauf an, dass in der Trennfläche des Schwenkgehäuses eine Luft führende Verbindung zwischen den Luftkanälen des Schmutzsaugers selbst und dem Innenraum des Schwenkgehäuses vorgenommen wird, sodass also die Flachfilter in der Trennfläche des Schwenkgehäuses angeordnet sind und der Innenraum des Schwenkgehäuses durch die Abreinigungsströme durchsetzt ist.The term "flat filter" as used herein is not intended to be limiting. Instead of a flat filter, it is possible to use any desired type of filter, for example filter fleeces, round filters, zig-zag filters, folded filters of any type or the like. It is only important that an air-conducting connection between the air ducts of the vacuum cleaner itself and the interior of the pivot housing is made in the separation surface of the pivot housing, so that the flat filter are arranged in the separation surface of the pivot housing and the interior of the pivot housing passes through the Abreinigungsströme is.

Das Schwenkgehäuse ist demnach sowohl von einem dort einlaufenden Luftstrom, als auch von einem dort auslaufenden Luftstrom durchsetzt, wie anhand der Zeichnungen später beschrieben wird.Accordingly, the swivel housing is penetrated both by an air stream entering there and by an air stream leaving there, as will be described later with reference to the drawings.

In einer weiteren vorteilhaften Ausführungsform ist das Schwenkgehäuse mindestens zweigeteilt ausgebildet. Die beiden Schwenkgehäuseteile können dann jeweils Scharniere im seitlichen Bereich des Staubsaugergehäuses auf- und zugeklappt werden. So kann beispielsweise jeweils ein Schwenkgehäuseteil einen Flachfilter aufweisen, wodurch die Filter leicht zugänglich sind. Ebenso wäre die Anordnung von einem Flachfilter bei einem Schwenkgehäuseteil möglich, während der andere Schwenkgehäuseteil die Absaugöffnung für den Saugkanal aufweist.In a further advantageous embodiment, the pivot housing is formed at least two parts. The two swivel housing parts can then each hinges in the lateral region of the vacuum cleaner housing open and closed. Thus, for example, each swivel housing part have a flat filter, whereby the filters are easily accessible. Likewise, the arrangement of a flat filter in a swivel housing part would be possible, while the other swivel housing part has the suction opening for the suction channel.

Der Erfindungsgegenstand der vorliegenden Erfindung ergibt sich nicht nur aus dem Gegenstand der einzelnen Patentansprüche, sondern auch aus der Kombination der einzelnen Patentansprüche untereinander.The subject of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims with each other.

In Figur 1 ist allgemein ein Schmutzsauger 1 mit einem beliebig geformten Gehäuse 2 dargestellt, welches im Wesentlichen aus einem Unterteil 5 und einem Oberteil 6 besteht. Die beiden Teile 5, 6 können trennbar zueinander ausgebildet sein, wobei im Unterteil 5 der Schmutzbehälter 12 angeordnet ist, der schlüssig über einen Einlassstutzen 3 die mit Schmutz beladene Luft in Pfeilrichtung 13 empfängt.In FIG. 1 is generally a vacuum cleaner 1 shown with an arbitrarily shaped housing 2, which consists essentially of a lower part 5 and an upper part 6. The two parts 5, 6 may be formed separable from each other, wherein in the lower part 5 of the dirt container 12 is arranged, which receives conclusively via an inlet nozzle 3, the dirt-laden air in the direction of arrow 13.

Im Oberteil 6 des Gehäuses 2 ist bevorzugt der Motor 22 und die davon angetriebene Turbine 23 angeordnet. Das Gehäuse 2 ist über Rollen 4 am Erdboden abgestützt.In the upper part 6 of the housing 2, the motor 22 and the turbine 23 driven therefrom are preferably arranged. The housing 2 is supported by rollers 4 on the ground.

Gemäß Figur 1 besteht die Erfindung darin, dass mindestens eine Seitenfläche oder eine Gehäusekante im Oberteil 6 als Schwenkgehäuse 7 ausgebildet ist, wobei das Schwenkgehäuse 7 über obere Scharniere 8 in einer horizontalen Schwenkachse 9 in den Pfeilrichtungen 10 zu öffnen und zu schließen ist.According to FIG. 1 the invention consists in that at least one side surface or a housing edge is formed in the upper part 6 as a swivel housing 7, wherein the swivel housing 7 is to be opened and closed by upper hinges 8 in a horizontal pivot axis 9 in the directions of arrows 10.

In einer alternativen Ausführungsform kann es auch vorgesehen sein, dass statt der oberen Schwenkachse 9 eine untere Scharnierachse 11 vorgesehen ist, sodass das Schwenkgehäuse 7 nicht von unten nach oben verschwenkt wird, sondern umgekehrt von oben nach unten.In an alternative embodiment, it may also be provided that instead of the upper pivot axis 9, a lower hinge axis 11 is provided, so that the pivot housing 7 is not pivoted from bottom to top, but vice versa from top to bottom.

Es ist zeichnerisch nicht dargestellt, dass auch eine seitliche Schwenkachse vorgesehen sein könnte, die im Bereich etwa gleichgerichtet wie die Trennfläche 37 ausgebildet ist, sodass das gesamte Schwenkgehäuse 7 um eine Seitenfläche schwenkbar ausgebildet ist.It is not shown in the drawing, that a lateral pivot axis could be provided which is approximately rectified in the area as the separation surface 37 is formed, so that the entire pivot housing 7 is formed pivotable about a side surface.

Demnach kommt es nur darauf an, dass das Schwenkgehäuse 7 in mindestens einer Schwenkachse 9, 11 schwenkbar am Oberteil 6 des Gehäuses 2 des Schmutzsaugers 1 angeordnet ist, und dass im Bereich des Schwenkgehäuses 7 nun die erfindungsgemäßen ein oder mehreren Flachfilter 16, 26 angeordnet sind.Accordingly, it is only important that the pivot housing 7 in at least one pivot axis 9, 11 is pivotally mounted on the upper part 6 of the housing 2 of the vacuum cleaner 1, and that in the region of the pivot housing 7, the inventive one or more flat filters 16, 26 are arranged ,

In Figur 2 ist als erste Ausführungsform dargestellt, dass im Innenraum des Schmutzbehälters 12 nun ein Schmutz 14 angesammelt wird, der nachfolgend mit zunehmendem Füllungsstand des Schmutzbehälters 12 sich auch an den Seitenflächen des Flachfilters 16 als Ablagerung 15 absetzt.In FIG. 2 is shown as a first embodiment, that in the interior of the dirt container 12 now a dirt 14 is accumulated, which subsequently settles with increasing filling level of the dirt container 12 also on the side surfaces of the flat filter 16 as a deposit 15.

Mit zunehmendem Füllungsstand des Schmutzes 14 im Schmutzbehälter 12 steigen dann die Ablagerungen 15 seitlich an der Ansaugfläche des Flachfilters 16 hoch, wobei wichtig ist, dass immer noch ein oberer Bereich des Flachfilters mit einem Luftstrom 18 beströmbar ist. Der obere Bereich kann daher lange genutzt werden, während die Ablagerungen 15 sich bereits schon bei dem in Pfeilrichtung 17 durch den Flachfilter hindurchgehenden Abreinigungsstrom mittig abgesetzt haben.With increasing filling level of the dirt 14 in the dirt container 12 then the deposits 15 rise laterally on the suction surface of the flat filter 16 high, it is important that still an upper portion of the flat filter with a stream of air 18 is durchrömbar. The upper region can therefore be used for a long time, while the deposits 15 have already settled centrally in the cleaning direction in the direction of arrow 17 through the flat filter.

Der schräg in Richtung auf den Schmutzbehälter 12 eingebaute Flachfilter 16 hat den weiteren Vorteil, dass die Anhaftungswirkung der Ablagerungen 15 an den Faltungen des Flachfilters 16 nicht so stark sind, sodass auch hierdurch eine gewisse Abreinigungswirkung gegeben ist.The obliquely installed in the direction of the dirt container 12 flat filter 16 has the further advantage that the adhesion effect of the deposits 15 on the folds of the flat filter 16 are not so strong, so that a certain Abreinigungswirkung is also given.

Der im Innenraum des Flachfilters 16 eindringende Abreinigungsluftstrom (Pfeilrichtung 17) wird im Gehäuseinneren des Schwenkgehäuses 7 umgelenkt und wird anschließend in Pfeilrichtung 20 in den dort angeordneten Saugkanal 21 eingeleitet.The in the interior of the flat filter 16 penetrating Abreinigungsluftstrom (arrow 17) is deflected in the housing interior of the pivot housing 7 and is then introduced in the direction of arrow 20 in the suction channel 21 arranged there.

Dies setzt voraus, dass die Trennebene 37 (das ist die schräge Gehäusekante des Schwenkgehäuses 7) luftschlüssig mit der zugeordneten Ebene im Schmutzsaugergehäuse verbunden ist. Der Saugkanal 21 ist also mit seiner Mündung luftschlüssig an eine zugeordnete Durchbrechung in der Trennfläche 37 des Schwenkgehäuses verbunden.This assumes that the parting plane 37 (that is, the oblique housing edge of the pivot housing 7) is connected in an air-tight manner with the associated plane in the vacuum cleaner housing. The suction channel 21 is thus connected with its mouth in an air-tight manner to an associated opening in the separating surface 37 of the swivel housing.

Der Luftstrom wird in Pfeilrichtung 20 in den Saugkanal 21 eingeleitet, wobei der Luftstrom durch eine Turbine 23 erzeugt wird, welche von einem Motor 22 angetrieben ist. Der Luftstrom verlässt anschließend den Ausblaskanal 24 in Pfeilrichtung 25.The air flow is introduced in the direction of arrow 20 into the suction channel 21, wherein the air flow is generated by a turbine 23 which is driven by a motor 22. The air flow then leaves the exhaust duct 24 in the direction of arrow 25th

Wichtig ist demnach, dass zwischen der einen schrägen Trennfläche 37 des Schwenkgehäuses 7 und der zugeordneten Fläche im Gehäuse 2 des Schmutzsaugers 1 eine Trennebene 19 angeordnet ist.It is therefore important that a separating plane 19 is arranged between the one inclined separating surface 37 of the swivel housing 7 and the associated surface in the housing 2 of the dirty vacuum cleaner 1.

Somit ist es erstmals möglich, dass beim Hochschwenken des Schwenkgehäuses 7 um die Scharniere 8 (Figur 2) und die Scharnierachse 9, der gesamte Flachfilter 16 mit allen Einbauteilen von außen her leicht zugänglich ist.Thus, it is possible for the first time that when pivoting the pivot housing 7 about the hinges 8 (FIG. FIG. 2 ) and the hinge axis 9, the entire flat filter 16 with all mounting parts from the outside is easily accessible.

Die Figur 3 zeigt eine gegenüber Figur 2 abgewandelte Ausführungsform, bei der statt eines Flachfilters 16 nun zwei parallel mit dem Luftstrom in Pfeilrichtung 17 beströmte Flachfilter 16, 26 aufgrund des Unterdrucks im Schmutzsaugerbehälter angeordnet sind. Ansonsten gelten für die gleichen Teile die gleichen Bezeichnungen.The FIG. 3 shows one opposite FIG. 2 modified embodiment in which instead of a flat filter 16 now two parallel with the air flow in the direction of arrow 17 flowed flat filter 16, 26 are arranged due to the negative pressure in the dirt suction tank. Otherwise, the same terms apply to the same parts.

Die Figur 3 zeigt im Vergleich zur Figur 2 noch, dass der Innenraum des Schwenkgehäuses 7 gegenüber der Atmosphäre abgedichtet ist, sodass in der Trennebene 19 eine luftdichte Abdichtung in Richtung auf das Gehäuse 2 des Schmutzsaugers 1 gegeben ist, und lediglich eine Luft führende Absaugöffnung 27 abdichtend den Saugkanal 21 des Gehäuses 2 mit dem Innenraum des Schwenkgehäuses 7 verbindet.The FIG. 3 shows in comparison to FIG. 2 Still, that the interior of the pivot housing 7 is sealed from the atmosphere, so that in the parting plane 19, an airtight seal in the direction of the housing 2 of the Suction sucker 1 is given, and only an air-leading suction port 27 sealingly connects the suction channel 21 of the housing 2 with the interior of the pivot housing 7.

Figur 4 zeigt als weitere Ausführungsform, dass im Innenraum des Schwenkgehäuses 7 auch eine Abreinigungsvorrichtung beliebiger Art angeordnet sein kann. FIG. 4 shows as a further embodiment, that in the interior of the pivot housing 7, a cleaning device of any kind can be arranged.

Als Beispiel ist in Figur 4 eine Abreinigungsvorrichtung 28 dargestellt, die im Wesentlichen aus einem 3-Wegeventil 30 besteht. Das Ventilküken 31 ist in verschiedenen Drehrichtungen verdrehbar.As an example, in FIG. 4 a cleaning device 28 is shown, which consists essentially of a 3-way valve 30. The valve plug 31 is rotatable in different directions of rotation.

In der eingezeichneten Stellung ist die Normalstellung der Flachfilter 16, 26 gezeigt, wobei beide Flachfilter 16, 26 von dem Absaugluftstrom durchströmt werden, der dann in Pfeilrichtung 20 über die Absaugöffnung 27 in den Saugkanal 21 gelangt.In the illustrated position, the normal position of the flat filter 16, 26 is shown, wherein both flat filters 16, 26 are flowed through by the suction air flow, which then passes in the direction of arrow 20 via the suction opening 27 into the suction channel 21.

Wird jedoch das Ventilküken 31 des 3-Wegeventils 30 um 90 Grad gedreht, erfolgt eine luftschlüssige Verbindung des Kanalstücks 32 mit dem Kanalstück 33, wobei das Kanalstück 34 abgeschlossen ist.However, if the valve plug 31 of the 3-way valve 30 is rotated by 90 degrees, an air-tight connection of the channel piece 32 with the channel piece 33, wherein the channel piece 34 is completed.

Auf diese Weise wird Umgebungsluft durch das mit der Umgebungsluft verbundene Kanalstück 33 in Pfeilrichtung 35 angesaugt und werden dem an der Rückseite des einen oder mehreren Flachfilter 16 angeordneten Faltenfilters 26 zugeführt, wobei über diesen Luftkanal dann die Luft im Gegensatz zur Pfeilrichtung 17 die Faltenfilter 16, 26 von hinten beströmt und die Schmutzpartikel abgesprengt werden.In this way, ambient air is sucked in through the ambient air connected to the channel piece 33 in the direction of arrow 35 and are fed to the arranged on the back of the one or more flat filter 16 folded filter 26, wherein the air over this air duct then in contrast to the arrow 17, the pleated filter 16, 26 flows from the back and the dirt particles are blasted off.

Die Figur 5 zeigt eine weitere Abreinigungsvorrichtung, wie sie Gegenstand der DE 101 01 219 B4 ist.The FIG. 5 shows another cleaning device, as they are the subject of DE 101 01 219 B4 is.

Im gezeigten Ausführungsbeispiel können hierbei zwei Flachfilter 16, 26 getrennt voneinander abgereinigt werden, wobei während der Abreinigung des einen Flachfilters 16 das andere Flachfilter 26 noch in Betrieb bleibt. In der Normalstellung dienen jedoch beide Flachfilter 16, 26 zur Schmutzabreinigung eines Schmutzstromes in Pfeilrichtung 17.In the exemplary embodiment shown here, two flat filters 16, 26 can be cleaned separately from each other, wherein during the cleaning of a flat filter 16, the other flat filter 26 is still in operation. In the normal position, however, both flat filters 16, 26 serve to clean the dirt of a dirt flow in the direction of arrow 17.

Im gezeigten Ausführungsbeispiel wird der Flachfilter 16 abgereinigt, und sein Abreinigungsluftstrom wird als Abreinigungsluftstrom 36 auf das andere Flachfilter 26 geleitet, wobei entsprechend der Abreinigungsstellung der nicht näher dargestellten Abreinigungsvorrichtung die beiden Absaugöffnungen 27a, 27b in Luft führender Verbindung mit der Turbine 23 sind.In the illustrated embodiment, the flat filter 16 is cleaned, and its Abreinigungsluftstrom is passed as Abreinigungsluftstrom 36 to the other flat filter 26, wherein according to the Abreinigungsstellung the cleaning device, not shown, the two suction openings 27 a, 27 b in air leading connection to the turbine 23.

Wichtig bei der Erfindung ist demnach, dass das Schwenkgehäuse ein vollkommen abgeschlossenes, luftdichtes Gehäuse ist, welches innenseitig eine schräge Trennfläche 37 aufweist, und welches ferner zwei parallel zueinander angeordnete Seitenflächen 39 aufweist, die sich im senkrechten Winkel an eine vordere Frontfläche 38 anschließen, die wiederum im rechten Winkel an eine obere Deckfläche 40 anschließen.Important in the invention is therefore that the pivot housing is a completely sealed, airtight housing, which has on the inside an oblique separation surface 37, and which further comprises two mutually parallel side surfaces 39, which adjoin each other at a vertical angle to a front surface 38, the again at a right angle to an upper deck surface 40 connect.

Die genannten Flächen 38, 39, 40 können in beliebiger Weise profiliert, gebogen oder gekrümmt ausgebildet sein. Das gesamte Schwenkgehäuse kann auch halbrund, oval oder eckig ausgebildet sein.Said surfaces 38, 39, 40 may be profiled, bent or curved in any desired manner. The entire pivot housing can also be formed semicircular, oval or angular.
