Description

Die Erfindung betrifft einen Staubsauger entspreschend dem Oberbegriff des Patentanspruchs 1. Bei diesem Staubsauger kann es sich sowohl um einen Bodenstaubsauger als auch um einen Handstaubsauger handeln.The invention relates to a vacuum cleaner according to the preamble of claim 1. This vacuum cleaner can be both a floor vacuum cleaner and a handheld vacuum cleaner.

Bei den bisher bekannten Staubsaugern besteht das Staubsaugergehäuse üblicherweise aus einem unteren und einem oberen Gehäuseteil, die nach dem Einbau der in das Gehäuse aufzunehmenden Bauteile, wie beispielsweise des Motors und der zugehörigen Anschlüsse, fest miteinander verbunden werden. Der den Staubraum überdeckende Teil des Gehäuses ist mit einer verschwenkbaren Klappe verbunden, die den Zugang zu dem Staubraum zum Austausch des Staubbeutels ermöglicht und im geschlossenen Zustand einen luftdichten Verschluß des Staubraumes bildet.In the previously known vacuum cleaners, the vacuum cleaner housing usually consists of a lower and an upper housing part, which are firmly connected to one another after the installation of the components to be accommodated in the housing, such as the motor and the associated connections. The part of the housing which covers the dust space is connected to a pivotable flap which allows access to the dust space for exchanging the dust bag and forms an airtight seal of the dust space in the closed state.

Dieser Aufbau der bisher üblichen Staubsaugergehäuse ist aufwendig und erfordert einen verhältnismäßig großen Arbeits-und Zeitaufwand bei der Montage des Staubsaugers. Die verschwenkbare Klappe des Staubraums neigt zudem bei längerem Gebrauch zur Beschädigung, die insbesondere bei nicht sachgemäßer Betätigung der Klappe dazu führen kann, daß die Halterung der Klappe und der erforderliche dichte Verschluß nicht mehr gewährleistet sind. Zur Wiederherstellung der Funktionsfähigkeit des Staubsaugers ist es dann erforderlich, die Klappe auszutauschen. Außerdem ist der Anwendungsbereich des oben beschriebenen Staubsaugers in der Regel auf die reine Saugtätigkeit begrenzt.This construction of the vacuum cleaner housings which have been customary to date is complex and requires a relatively large amount of work and time when assembling the vacuum cleaner. The pivotable flap of the dust chamber also tends to damage during prolonged use, which in particular can result in improper actuation of the flap, that the mounting of the flap and the required tight closure can no longer be guaranteed. It is then necessary to replace the flap in order to restore the functionality of the vacuum cleaner. In addition, the scope of the The vacuum cleaner described above is usually limited to the pure suction activity.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Staubsauger derart zu verbessern, daß der Aufbau des Staubsaugergehäuses vereinfacht und die Montage des Staubsaugers erleichert ist, so daß die Herstellungs- und Wartungskosten des Staubsaugers verringert werden, und daß der Anwendungsbereich insbesondere der handlichen Kleinstaubsauger wie z.B. Autostaubsauger erweitert wird.The present invention has for its object to improve a vacuum cleaner in such a way that the construction of the vacuum cleaner housing is simplified and the assembly of the vacuum cleaner is simplified, so that the manufacturing and maintenance costs of the vacuum cleaner are reduced, and that the area of application, in particular of the handy small vacuum cleaners such as e.g. Car vacuum cleaner is being expanded.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst. Weitere vorteilhafte Ausgestaltungen ergeben sich aus den Ansprüchen 2 bis 18.This object is achieved by the features specified in the characterizing part of claim 1. Further advantageous embodiments result from claims 2 to 18.

Der erfindungsgemäße Staubsauger hat ein aus zwei Teilen bestehendes Gehäuse, von denen das eine eine Schubladenform hat, in dem die in dem Gehäuse unterzubringenden Bauteile aufgenommen sind. Dieses schubladenförmige Gehäuseteil ist verschiebbar in einem einen Rahmen bildenden zweiten Gehäuseteil aufgenommen, das die offene Fläche des schubladenförmigen Gehäuseteils dicht verschließen kann. Damit kann das den Staubraum und den Motorraum enthaltende schubladenförmige Gehäuseteil aus dem anderen Gehäuseteil wie eine Schublade aus einem Schrank herausgezogen werden, um beispielsweise den Staubraum zu öffnen und den darin befindlichen Staubbeutel auszutauschen. Die Montage des Staubsaugers ist denkbar einfach, da nach Einbau der in dem Gehäuse aufzunehmenden Bauteile in das schubladenförmige Gehäuseteil lediglich dessen Einschub in das zweite Gehäuseteil erforderlich ist, um den Zusammenbau des Gehäuses zu vollenden. Es entfällt die bisher übliche feste Verbindung zwischen einem unteren und einem oberen Gehäuseteil und die Anordnung einer verschwenkbaren Klappe im Bereich des Staubraums.The vacuum cleaner according to the invention has a housing consisting of two parts, one of which has a drawer shape in which the components to be accommodated in the housing are accommodated. This drawer-shaped housing part is slidably received in a second housing part forming a frame, which can tightly close the open surface of the drawer-shaped housing part. The drawer-shaped housing part containing the dust chamber and the motor chamber can thus be pulled out of the other housing part like a drawer from a cabinet, for example to open the dust chamber and to replace the dust bag located therein. The assembly of the vacuum cleaner is extremely simple, since after the components to be accommodated in the housing have been installed in the drawer-shaped housing part, only its insertion into the second housing part is required in order to complete the assembly of the housing. The hitherto usual fixed connection between a lower and an upper housing part and the arrangement of a pivotable flap in the area of the dust chamber are eliminated.

Der erforderliche dichte Abschluß zwischen den beiden gegeneinander verschiebbar angeordneten Gehäuseteilen wird durch geeignete Dichtungen sichergestellt. Es ist vorzugsweise ein Rastmechnismus vorgesehen, der die dichte Verschlußstellung der beiden Gehäuseteile festlegt.The required tight seal between the two mutually displaceable housing parts is ensured by suitable seals. A locking mechanism is preferably provided which defines the tight closed position of the two housing parts.

Obwohl das erfindungsgemäße Prinzip sowohl für Boden- als auch für Handstaubsauger verwendbar ist, ist es besonders gut für kleine und leichte Handstaubsauger wie beispielsweise Autostaubsauger und batteriebetriebene Kleinstaubsauger geeignet, bei denen die verschiebbar ineinandergreifenden Gehäuseteile besonders leicht zu handhaben sind.Although the principle according to the invention can be used for both floor and handheld vacuum cleaners, it is particularly well suited for small and light handheld vacuum cleaners such as car vacuum cleaners and battery-operated small vacuum cleaners, in which the displaceably interlocking housing parts are particularly easy to handle.

Das schubladenförmige erste Gehäuseteil sollte zweckmäßigerweise eine offene Oberseite haben, da die aufzunehmenden Bauteile von oben leicht einbaubar und zum Austausch bequem zugänglich sind. Die Anordnung könnte jedoch auch so getroffen sein, daß das erste Gehäuseteil eine offene Seitenfläche hat, wobei es auch denkbar ist, daß zwei Seitenflächen ganz oder teilweise offen sind.The drawer-shaped first housing part should expediently have an open upper side, since the components to be accommodated are easy to install from above and are easily accessible for replacement. However, the arrangement could also be such that the first housing part has an open side surface, it also being conceivable that two side surfaces are completely or partially open.

Das zweite Gehäuseteil, das eine Art Rahmen bildet, kann das erste Gehäuseteil in der Verschlußstellung mit Ausnahme einer Stirnseite vollständig umgreifen. Bei dieser besonders bevorzugten Ausführungsform ist eine gute Führung der inneren Schublade mit geeigneten Führungsbauteilen erreichbar, da sich die Schublade wie in einer Schachtel bewegt. Dabei ist auch auf einfache Weise der erforderliche dichte Abschluß sicherzustellen.The second housing part, which forms a kind of frame, can completely encompass the first housing part in the closed position, with the exception of one end face. In this particularly preferred embodiment, good guidance of the inner drawer can be achieved with suitable guide components, since the drawer moves as in a box. The required tight seal must also be ensured in a simple manner.

Alternativ hierzu kann das zweite Gehäuseteil das erste Gehäuseteil lediglich U-förmig überdecken.Alternatively, the second housing part can only cover the first housing part in a U-shape.

Das schubladenförmige Gehäuseteil ist durch Trennwände in mehrere Innenräume aufgeteilt, wodurch zumindest ein in Öffnungsrichtung vorderer Staubbeutelraum und ein hinterer Motorraum entstehen. Mit besonderem Vorteil ist vorgesehen, daß neben dem vorderen Staubbeutelraum auch ein Fach zur Aufnahme von Zubehörteilen ausgebildet ist, so daß diese Zubehörteile bei der Benutzung des Staubsaugers stets zur Hand sind. Wenn der Staubsauger batteriebetrieben ist, kann auch ein gesondertes Fach für die Batterien vorgesehen sein,z.B. an der Unterseite der Schublade in einer Gehäuseteilvertiefung.The drawer-shaped housing part is divided into several interior spaces by partition walls, whereby at least one dust bag compartment in the opening direction and a rear engine compartment are created. It is particularly advantageous that, in addition to the front dust bag compartment, there is also a compartment for holding accessories, so that these accessories are always at hand when using the vacuum cleaner. If the vacuum cleaner is battery-operated, a separate compartment for the batteries can also be provided, for example on the underside of the drawer in a recess in the housing part.

Es wird ferner vorgeschlagen, daß Anschläge den Austritt des schubladenförmigen Gehäuseteils aus dem zweiten Gehäuseteil so begrenzen, daß der Motorraum für einen Benutzer nicht zugänglich ist. Hierbei handelt es sich um eine Vorsichtsmaßnahme, die einen unsachgemäßen Eingriff in den Motorraum verhindert, während bei erforderlichen Reparaturmaßnahmen in dem Motorraum die Anschläge zu dessen Öffnung entfernt werden können.It is also proposed that stops limit the exit of the drawer-shaped housing part from the second housing part so that the engine compartment is not accessible to a user. This is a precautionary measure that prevents improper intervention in the engine compartment, while the stops for opening it can be removed in the case of necessary repair measures in the engine compartment.

Es wird ferner vorgeschlagen, daß bei einem mit einem angeformten Handgriff versehenen Staubsauger dieser Handgriff hohl ausgebildet und mit einer rückwärtigen Luftaustrittsöffnung versehen ist, wobei der innere Hohlraum des Handgriffs mit dem Motorraum des Gehäuses in Verbindung steht, und daß ein Umschaltschieber wahlweise die Luftaustrittsschlitze des Gehäuses oder die Verbindung zu dem Hohlraum des Handgriffs verschließen kann. Mit dieser Ausbildung ist der Staubsauger wahlweise als Gebläse verwendbar, um beispielsweise einen Holzkohlengrill anzuheizen. Diese zusätzliche Funktionsweise ist ersichtlich insbesondere bei einem batteriebetriebenen Kleinstaubsauger vorteilhaft.It is further proposed that in a vacuum cleaner provided with a molded handle, this handle is hollow and provided with a rear air outlet opening, the inner cavity of the handle communicating with the engine compartment of the housing, and that a switch slide selectively the air outlet slots of the housing or can close the connection to the cavity of the handle. With this design, the vacuum cleaner can optionally be used as a blower, for example to heat a charcoal grill. This additional mode of operation is particularly advantageous in the case of a battery-operated small vacuum cleaner.

Um gegebenenfalls auch unabhängig von einer internen Energiequelle den Staubsauger betreiben zu können, ist es vorteilhaft vorgesehen, an der Unterseite des schubladenförmigen Gehäuseteiles eine Vertiefung zur Aufnahme einer Energieversorgungseinrichtung anzubringen. Es kann sich dabei beispielsweise um handelsübliche Batterien oder einen wiederaufladbaren Akkumulator handeln. Diese Energieversorgungseinrichtungen sind von der Unterseite des herausgezogenen schubladenförmigen Gehäuseteiles zu erreichen, wobei die Vertiefung mit einem abnehmbaren Deckel verschlossen sein kann.In order to also be able to operate the vacuum cleaner independently of an internal energy source, it is advantageously provided to provide a recess on the underside of the drawer-shaped housing part for receiving an energy supply device. It can be, for example, commercially available batteries or a rechargeable accumulator. These energy supply devices can be reached from the underside of the pulled-out drawer-shaped housing part, and the depression can be closed with a removable cover.

Um den Staubsauger jedoch auch an eine sich auch außerhalb des Gerätes befindliche Energiequelle anschließen zu können, ist eine zusätzliche Vertiefung in wenigstens einem der beiden Gehäuseteile vorgesehen. Diese Vertiefung dient zum Aufbewahren eines Stromkabels und kann bei Bedarf leicht geöffnet werden. Bei vorhandener externer Energiequelle kann der Motor des Staubsaugers dann auch in Betrieb genommen werden, ohne die interne Energiequelle zu belasten. Vorteilhaft ist die Ein-/Ausschaltvorrichtung so ausgeführt, daß bei herausgezogenem Gehäuseteil ein Ein-/Ausschalten des Staubsaugermotors nicht mehr möglich ist. Dies kann beispielsweise dadurch erreicht werden, daß die Verbindung der Energiequelle mit dem Motor bei herausgezogenem Gehäuseteil unterbrochen wird. Die Ein-/Ausschaltvorrichtung kann auch an einem der aus dem Gehäuseteil herausziehbaren Teile, insbesondere am schubladenförmigen Gehäuseteil befestigt sein, so daß sie bei herausgezogenem Gehäuseteil nicht mehr betätigbar ist.However, in order to be able to connect the vacuum cleaner to an energy source that is also outside the device, an additional depression is provided in at least one of the two housing parts. This recess is used to store a power cable and can be easily opened if necessary. If an external energy source is available, the motor of the vacuum cleaner can then also be started without stressing the internal energy source. The switch-on / switch-off device is advantageously designed such that it is no longer possible to switch the vacuum cleaner motor on / off when the housing part is pulled out. This can be achieved, for example, in that the connection of the energy source to the motor is interrupted when the housing part is pulled out. The on / off switch can also be attached to one of the parts that can be pulled out of the housing part, in particular to the drawer-shaped housing part, so that it can no longer be actuated when the housing part is pulled out.

Damit das schubladenförmige Gehäuseteil im geschlossem Zustand fest mit dem anderen Gehäuseteil verbunden bleibt, ist eine Arretierungsvorrichtung zwischen diesen beiden Gehäuseteilen vorgesehen. Die Arretierungsvorrichtung kann aus Verschlußzungen bestehen, die an dem schubladenförmigen Gehäuseteil angeordnet sind und in entsprechende Rastvorrichtungen des anderen Gehäuseteiles eingreifen. Ein Lösen dieser Arretierungsvorrichtung kann beispielsweise durch leichten Druck und gleichzeitiges Ziehen an dem schubladenförmigen Gehäuseteil bewirkt werden.So that the drawer-shaped housing part remains firmly connected to the other housing part in the closed state, a locking device is provided between these two housing parts. The locking device can consist of locking tongues which are arranged on the drawer-shaped housing part and engage in corresponding locking devices of the other housing part. This locking device can be released, for example, by slight pressure and simultaneous pulling on the drawer-shaped housing part.

Durch ein zusätzliches Luftkanalsystem im inneren des Staubsaugers und eine entsprechende Schalteinrichtung kann erreicht werden, daß die Abluft des Staubsaugers nach vorne durch den Saugstutzen austritt. Durch diese weitere Ausführungsform wird eine gute Handhabung des Staubsaugers als Gebläse erreicht.An additional air duct system in the interior of the vacuum cleaner and a corresponding switching device can ensure that the exhaust air from the vacuum cleaner exits to the front through the suction nozzle. This further embodiment ensures good handling of the vacuum cleaner as a blower.

In Fig. 1 ist das Gehäuse 1 eines Bodenstaubsaugers mit den hinteren Rädern 2 und dem vorderen Saugstutzen 3 dargestellt. Das Gehäuse 1 besteht aus einem schubladenförmigen ersten Gehäuseteil 4, das in ein zweites, schachtelförmiges Gehäuseteil 5 verschiebbar aufgenommen ist. Das schubladenförmige Gehäuseteil 4 hat eine offene Oberseite 6, während die übrigen Umfangsflächen geschlossen sind. Das zweite Gehäuseteil 5 umgreift das erste Gehäuseteil 4 in der Verschlußstellung vollständig mit Ausnahme der vorderen Stirnseite 7.In Fig. 1, the housing 1 of a vacuum cleaner with the rear wheels 2 and the front suction nozzle 3 is shown. The housing 1 consists of a drawer-shaped first housing part 4 which is slidably received in a second box-shaped housing part 5. The drawer-shaped housing part 4 has an open top 6, while the other peripheral surfaces are closed. The second housing part 5 completely engages around the first housing part 4 in the closed position, with the exception of the front end face 7.

Das erste Gehäuseteil 4 ist durch zwei Trennwände 8 und 9 in mehrere Innenräume aufgeteilt, wodurch ein vorderer Staubbeutelraum 10, ein danebenliegendes Fach 11 für Zubehörteile des Staubsaugers und ein hinterer Motorraum 12 entstehen.The first housing part 4 is divided into two interior spaces by two partitions 8 and 9, which creates a front dust bag space 10, an adjacent compartment 11 for accessories of the vacuum cleaner and a rear engine compartment 12.

Nicht dargestellte Anschläge begrenzen den Auszug des Gehäuseteils 4 aus dem Gehäuseteil 5 derart, daß der Motorraum 12 für einen Benutzer nicht zugänglich ist, wobei jedoch der Staubbeutelraum 10 und das Zubehörfach 11 soweit geöffnet werden können, daß der Staubbeutel 13 leicht austauschbar ist und die nicht dargestellten Zubehörteile bequem entnommen werden können.Stops, not shown, limit the extraction of the housing part 4 from the housing part 5 in such a way that the engine compartment 12 is not accessible to a user, but the dust bag compartment 10 and the accessory compartment 11 can be opened to such an extent that the dust bag 13 is easily replaceable and not shown accessories can be easily removed.

In Fig. 2 ist das Gehäuse 1 des Handstaubsaugers im geschlossenen Zustand dargestellt, so daß lediglich das zweite Gehäuseteil 5 erkennbar ist. An dem rückwärtigen Ende des Gehäuseteils 5 ist ein Handgriff 14 angeformt, der hohl ausgebildet ist und mit einer rückwärtigen Öffnung 15 versehen ist. Der Hohlraum des Handgriffs 14 steht mit dem Motorraum des Staubsaugers in Verbindung.In Fig. 2, the housing 1 of the handheld vacuum cleaner is shown in the closed state, so that only the second housing part 5 can be seen. At the rear end of the housing part 5, a handle 14 is formed, which is hollow and is provided with a rear opening 15. The cavity of the handle 14 communicates with the engine compartment of the vacuum cleaner.

In der Nähe des Ansatzes des Handgriffs 14 an dem oberen, rückwärtigen Ende des Gehäuseteils 5 befinden sich Luftaustrittsschlitze 16 im Bereich der Oberseite des Gehäuses. Ein nicht dargestellter Umschaltschieber kann wahlweise die Luftaustrittsschlitze 16 des Gehäuseteils 5 oder die Verbindung zu dem Hohlraum des Handgriffs 14 verschließen, so daß der Handstaubsauger zusätzlich als Gebläse verwendbar ist. In diesem Fall strömt die Luft aus dem Motorraum in Richtung der Pfeile A in Fig. 2 durch den Handgriff 14 durch und tritt aus der Öffnung 15 aus.In the vicinity of the attachment of the handle 14 at the upper, rear end of the housing part 5 there are air outlet slots 16 in the area of the top of the housing. A switch slide, not shown, can optionally close the air outlet slots 16 of the housing part 5 or the connection to the cavity of the handle 14, so that the handheld vacuum cleaner can also be used as a blower. In this case, the air flows out of the engine compartment in the direction of arrows A in FIG. 2 through the handle 14 and emerges from the opening 15.

Die Verschlußstellung der beiden Gehäuseteile 4 und 5 ist durch einen Rastmechanismus festgelegt, der durch eine Öffnungstaste 17 im Bereich der Oberseite des Gehäuses freigegeben werden kann.The closed position of the two housing parts 4 and 5 is determined by a locking mechanism which can be released by an opening button 17 in the area of the top of the housing.

Wie ferner aus den Fig. 2 und 3 zu entnehmen ist, ist in der Mitte des Gehäuseteils 5 eine in Richtung des Saugstutzens verlaufende, längliche Gehäuseaussparung 19 vorgesehen. In diese Gehäuseaussparung greift ein Bolzen 18 ein, der im betriebsgemäßen Zustand (Fig. 2) des Handstaubsaugers am rückwärtigen Ende der Gehäuseaussparung 19 anliegt. Der Bolzen 18 ist mit dem schubladenförmigen Gehäuseteil 4 fest verbunden und ragt nicht in den dahinterliegenden Raum hinein.As can also be seen from FIGS. 2 and 3, an elongated housing recess 19 extending in the direction of the suction nozzle is provided in the center of the housing part 5. A pin 18 engages in this housing recess, which, in the operational state (FIG. 2) of the hand-held vacuum cleaner, bears against the rear end of the housing recess 19. The bolt 18 is firmly connected to the drawer-shaped housing part 4 and does not protrude into the space behind it.

Wie Fig. 3 zeigt, gleitet der Bolzen 18 beim Herausziehen des Gehäuseteils 4 in der Gehäuseaussparung 19, bis er gegen das als Ausziehanschlag 20 dienende Ende der Aussparung 19 zur Anlage kommt. Da die Oberseite des Gehäuseteils 4 offen ist, sind der Staubbeutel und sich im Innenraum befindende Zubehörteile bequem auszuwechseln bzw. zu erreichen. Der dahinterliegende Motorraum bleibt dagegen durch das Gehäuseteil 5 abgedeckt. Zwischen dem Teil des Innenraums, der den Staubbeutel und die Zubehörteile enthält, und dem Motorraum befindet sich eine durchgehende Trennwand 22. Zu Wartungs-und Reparaturarbeiten, bei denen der Motorraum erreicht werden muß, ist der Ausziehanschlag 20, beispielsweise durch Eindrücken des Bolzens 18 oder andere Maßnahmen zu überwinden.As shown in FIG. 3, the bolt 18 slides in the housing recess 19 when the housing part 4 is pulled out until it comes to bear against the end of the recess 19 serving as a pull-out stop 20. Since the top of the housing part 4 is open, the dust bag and accessories located in the interior can be easily replaced or reached. The engine compartment behind it, however, remains covered by the housing part 5. A continuous partition 22 is located between the part of the interior which contains the dust bag and the accessories and the engine compartment. The pull-out stop 20 is for maintenance and repair work in which the engine compartment must be reached, for example by pushing in the bolt 18 or to overcome other measures.

An der Unterseite des Gehäuseteils 4 ist eine gegebenenfalls durch einen Deckel verschließbare Gehäusevertiefung 23 vorgesehen. In ihr können die Stromversorgungseinrichtungen untergebracht werden, wie Batterien oder ein Akku. Ferner kann diese Vertiefung 23 auch zusätzlich ein Stromführungskabel, möglicherweise sogar auf einer entsprechenden Kabelhaspel aufnehmen, dessen eines an eine Stromquelle - wie beispielsweise einem Zigarettenanzünder in einem Kraftfahrzeug - anschließbares Ende an einer Stelle des Gehäuseteils 5 austritt. Ein Erneuern der Batterien kann bei herausgezogenem Gehäuseteil 4 an dessen Unterseite vorgenommen werden.On the underside of the housing part 4, a housing recess 23, which can be closed by a cover, is provided. The power supply devices, such as batteries or a rechargeable battery, can be accommodated in it. Furthermore, this recess 23 can also additionally receive a power cable, possibly even on a corresponding cable reel, the one end of which can be connected to a power source - such as a cigarette lighter in a motor vehicle - exits at a point on the housing part 5. The batteries can be renewed with the housing part 4 pulled out on its underside.

Weiterhin ist in Fig. 3 zu erkennen, daß zwischen dem schubladenförmigen Gehäuseteil und dem rahmenförmigen Gehäuseteil eine Steckverbindung vorgesehen ist. Diese Steckverbindung besteht aus Leiterzungen 26 und Gegenkontakten 27 . Durch Herausziehen des schubladenförmigen Gehäuseteils werden die Steckverbindungen getrennt, womit gleichzeitig die Verbindung der Energiequelle mit der Antriebseinheit bei herausgezogenem Gehäuseteil unterbrochen ist. Ferner ist eine Ein-/Ausschaltvorrichtung 21 zu erkennen, die an der Rückseite des schubladenförmigen Gehäuseteiles angebracht ist und in geschlossenem Zustand durch die Betätigungstaste 21ʹ betätigt werden kann. In herausgezogenem Zustand verbleibt die Betätigungstaste 21ʹ am rahmenförmigen Gehäuseteil, während sich die Ein-/Ausschaltvorrichtung 21 mit dem schubladenförmigen Gehäuseteil von der Betätigungstaste 21ʹ wegbewegt und somit nicht mehr betätigt werden kann.3 that a plug connection is provided between the drawer-shaped housing part and the frame-shaped housing part. This plug connection consists of conductor tongues 26 and mating contacts 27. By pulling out the drawer-shaped housing part the plug connections are separated, whereby the connection of the energy source to the drive unit is interrupted when the housing part is pulled out. Furthermore, an on / off switch 21 can be seen, which is attached to the rear of the drawer-shaped housing part and can be actuated in the closed state by the actuation button 21ʹ. In the pulled-out state, the actuation button 21ʹ remains on the frame-shaped housing part, while the on / off device 21 with the drawer-shaped housing part moves away from the actuation button 21ʹ and can therefore no longer be actuated.

Zwischen dem schubladenförmigen und dem rahmenförmigen Gehäuseteil ist eine Arretierungsvorrichtung 24 vorgesehen, um die beiden Gehäuseteile in geschlossenem Zustand fest zusammenzuhalten. Diese Arretierungsvorrichtung kann beispielsweise aus Verschlußzungen 25 bestehen, die an der Oberseite des schubladenförmigen Gehäuseteiles angebracht sind und mit - nicht gezeigten - korrespondierenden Rastvorrichtungen in Eingriff bringbar sind, welche am rahmenartigen Gehäuseteil vorgesehen sind.A locking device 24 is provided between the drawer-shaped and the frame-shaped housing part in order to hold the two housing parts firmly together in the closed state. This locking device can for example consist of locking tongues 25 which are attached to the top of the drawer-shaped housing part and can be brought into engagement with - not shown - corresponding locking devices which are provided on the frame-like housing part.

Anstelle des im Handgriff 14 untergebrachten Kanalsystems mit der rückwärtigen Öffnung 15 kann auch ein anderes Kanalsystem vorgesehen sein, welches in herausgezogenem Zustand des schubladenförmigen Gehäuseteiles den Abluftraum mit dem Saugstutzen verbindet. Dazu müssen dann die Austrittsschlitze 16 und der Saugstutzeneintritt in den Staubbeutel verschlossen werden. Das Verschließen der Austrittsschlitze 16 und des Saugstutzeneintrittes in den Staubbeutel kann entweder durch die Relativbewegung der beiden Gehäuseteile gegegeneinander mechanisch oder beim Einschalten des Motors 18 elektrisch betätigt werden. Die Zuluft würde durch den Abluftraum angesaugt werden und durch den Saugstutzen 3 wieder austreten.Instead of the duct system with the rear opening 15 accommodated in the handle 14, another duct system can also be provided which, when the drawer-shaped housing part is pulled out, connects the exhaust air space to the suction nozzle. For this purpose, the outlet slots 16 and the intake port inlet in the dust bag must then be closed. The closing of the outlet slots 16 and the intake port inlet into the dust bag can either be mechanically actuated by the relative movement of the two housing parts against one another or electrically when the motor 18 is switched on. The supply air would be sucked in through the exhaust air space and exit again through the suction nozzle 3.
