Description

Die Erfindung betrifft einen Staubsauger, insbesondere einen Bodenstaubsauger mit einem integrierten, herausnehmbaren Handstaubsauger.The invention relates to a vacuum cleaner, in particular a vacuum cleaner with an integrated, removable hand vacuum cleaner.

Bodenstaubsauger sind als Reinigungsgeräte im Haushalt seit vielen Jahrzehnten in unterschiedlichsten Ausführungsformen bekannt. Üblicherweise umfassen die Bodenstaubsauger ein Hauptgehäuse, das eine aus Sauggebläse und Motor bestehende Saugeinrichtung, eine Stromversorgungseinrichtung für die Saugeinrichtung, einen Staubsammelbehälter und geeignete Filter umfasst. Die Saugeinrichtung des Hauptgehäuses ist mit einer Saugöffnung verbunden, durch welche Staub und andere Verschmutzungen, wie beispielsweise Haare oder Nahrungsmittelreste aufgesaugt werden können. Die Saugöffnung kann in unterschiedlichster Weise mit dem Hauptgehäuse verbunden sein. Die Saugöffnung kann beispielsweise Teil einer Bürsteneinheit sein, die direkt über eine Gelenkverbindung mit dem Hauptgehäuse verbunden ist. Die Saugöffnung kann auch über Verbindungsrohre, beispielsweise Teleskoprohre, oder über einen flexiblen Verbindungsschlauch mit dem Hauptgehäuse verbunden sein. Der Bodenstaubsauger saugt den Staub oder der Schmutz mit Hilfe eines motorgetriebenen Gebläses, das im Hauptgehäuse eingebaut ist, zusammen mit der Ansaugluft durch diese Ansaugöffnung ein. Die angesaugte Luft und der Schmutz gelangen so in den im Hauptgehäuse angeordneten Staubsammelbehälter. Gemäß einer Variante wird der Schmutz dort in einem Filterbehälter, der für Staub oder Schmutz undurchlässig, für die mit eingesaugte Luft aber durchlässig ist, gesammelt, während die angesaugte Luft nach Passieren des Filterbeutels aus dem Hauptgehäuse ausgeblasen wird. Es sind auch Staubsauger bekannt, bei denen an Stelle eines Staubbeutels eine Fliehkraft-Staubabscheidereinrichtung vorgesehen ist, in welcher der angesaugte, Staub- und Schmutzpartikel enthaltende Luftstrom einer zyklonartigen Bewegung unterworfen wird, bei der sich die schwereren Staub- oder Schmutzpartikel auf Grund der auf sie wirkenden Fliehkraft an der Gehäusewand sammeln, während die weitgehend gereinigte Luft im Zentrum des Abscheiders abgezogen werden kann. Bodenstaubsauger weisen üblicherweise, abhängig von ihrer Konstruktion, entweder am Hauptgehäuse oder an der Bürsteneinheit Rollen auf, mit denen sie über die zu reinigende Fläche bewegt werden können.Underground vacuum cleaners are known as household cleaning appliances for many decades in a variety of embodiments. Typically, the cylinder vacuum cleaners comprise a main body comprising a suction fan and motor suction means, a suction means power supply means, a dust collecting container and suitable filters. The suction device of the main housing is connected to a suction opening, through which dust and other contaminants, such as hair or food residues can be absorbed. The suction opening can be connected in various ways with the main housing. The suction opening may for example be part of a brush unit, which is connected directly via a hinge connection with the main housing. The suction opening can also be connected via connecting pipes, for example telescopic pipes, or via a flexible connecting hose to the main housing. The vacuum cleaner sucks in the dust or dirt through this suction port with the help of a motor-driven blower installed in the main body together with the intake air. The sucked air and the dirt so get into the arranged in the main housing dust collector. According to a variant of the dirt is there in a filter container, which is impermeable to dust or dirt, but permeable to the air sucked in, collected, while the sucked air is blown out after passing through the filter bag from the main body. There are also vacuum cleaners are known in which instead of a dust bag, a centrifugal Staubabscheidereinrichtung is provided in which the sucked, dust and dirt particles containing air stream is subjected to a cyclone-like movement in which the heavier dust or dirt particles due to the on them Collecting centrifugal force on the housing wall, while the largely purified air can be removed in the center of the separator. Underground vacuum cleaners usually have, depending on their construction, either on the main body or on the Brush unit Rolls on which they can be moved over the surface to be cleaned.

Für kleinere Reinigungsarbeiten sind derartige Bodenstaubsauger oftmals zu sperrig und unhandlich. Daher sind seit vielen Jahren auch sogenannte Handstaubsauger kommerziell erhältlich, bei denen die Saugeinrichtung und die Staubbehälter so dimensioniert sind, dass sie hinsichtlich des Gewichts und der Abmessungen bequem mit einer Hand gehalten und benutzt werden können. Derartige Handstaubsauger eignen sich insbesondere für kleinere Reinigungsarbeiten, wie beispielsweise das Beseitigen von Brotkrümeln auf dem Esstisch oder das Reinigen von Polstermöbeln.For smaller cleaning such vacuum cleaner are often too bulky and unwieldy. Therefore, for many years, so-called hand vacuum cleaners are commercially available in which the suction device and the dust container are dimensioned so that they can be conveniently held and used in terms of weight and dimensions with one hand. Such hand vacuum cleaners are particularly suitable for minor cleaning work, such as removing breadcrumbs on the dining table or cleaning upholstered furniture.

Aus dem US-Patent US-A-4,467,493 ist ein Bodenstaubsauger bekannt, in dessen Hauptgehäuse eine Ausnehmung zur Aufnahme eines Handstaubsaugers ausgespart ist. Der Handstaubsauger ist durch eine geeignete Verriegelungsvorrichtung in der Ausnehmung fixiert, so dass der Handstaubsauger beim Betrieb des Bodenstaubsaugers nicht herausfallen kann. Wenn der Benutzer den Handstaubsauger verwenden will, kann er den Verriegelungsmechanismus lösen und den Handstaubsauger aus der Ausnehmung herausnehmen. Der Handstaubsauger der bekannten Vorrichtung weist eine von der Saugvorrichtung des Bodenstaubsaugers separate Saugvorrichtung auf, das ebenfalls ein motorgetriebenes Gebläse umfasst. Zum Antrieb des Gebläsemotors weist der Motor des Handstaubsaugers der US-A-4,467,493 in dem Handstaubsauger integrierte, auswechselbare Einwegbatterien auf. Nachteilig an der bekannten Vorrichtung ist, dass eine derartige Saugvorrichtung im Handstaubsauger zumindest dann, wenn eine zufriedenstellende Saugleistung erzielt werden soll, einen relativ hohen Energieverbrauch aufweist, so dass die Batterien des Handstaubsaugers relativ schnell entladen werden. Der Benutzer sieht sich daher häufig mit dem Problem konfrontiert, dass er beim Einsatz des Handstaubsaugers feststellen muss, dass der Ladezustand der Batterien keine zufriedenstellenden Saugergebnisse mehr gewährleistet, so dass zunächst ein Batteriewechsel erforderlich ist. Eine Erhöhung der Anzahl der Batterien in dem Handstaubsauger ist keine geeignete Lösung dieses Problems, da der Handstaubsauger dann schwer und unhandlich wird.From the U.S. Patent US-A-4,467,493 a canister vacuum cleaner is known, in the main housing a recess for receiving a hand vacuum cleaner is recessed. The hand vacuum cleaner is fixed by a suitable locking device in the recess, so that the hand vacuum cleaner during operation of the vacuum cleaner can not fall out. If the user wants to use the hand vacuum cleaner, he can release the locking mechanism and remove the hand vacuum cleaner from the recess. The hand vacuum cleaner of the known device has a suction device separate from the suction device of the vacuum cleaner, which likewise comprises a motor-driven fan. To drive the fan motor, the engine of the hand vacuum cleaner of US-A-4,467,493 in the hand vacuum cleaner integrated, replaceable disposable batteries. A disadvantage of the known device is that such a suction device in the hand vacuum cleaner, at least when a satisfactory suction power is to be achieved, has a relatively high energy consumption, so that the batteries of the hand vacuum cleaner are discharged relatively quickly. The user is therefore often faced with the problem that he must determine when using the handheld vacuum cleaner, that the state of charge of the batteries no longer ensure satisfactory suction, so that a first battery replacement is required. An increase in the number of batteries in the hand vacuum cleaner is not a suitable solution to this problem, since the hand vacuum cleaner is then heavy and unwieldy.

Der vorliegenden Erfindung liegt daher das technische Problem zu Grunde, einen Staubsauger der oben beschriebenen Art anzugeben, welcher einerseits einen Bodenstaubsauger und andererseits einen lösbar mit dem Bodenstaubsauger verbundenen Handstaubsauger umfasst, bei dem gewährleistet ist, dass der Handstaubsauger stets einen optimalen Ladezustand aufweist und daher im Bedarfsfall ohne aufwändigen Batteriewechsel sofort einsatzbereit ist.The present invention is therefore based on the technical problem of specifying a vacuum cleaner of the type described above, on the one hand a vacuum cleaner and on the other hand connected to the vacuum cleaner vacuum cleaner, which ensures that the hand vacuum always has an optimal state of charge and therefore in If necessary, it can be used immediately without complex battery replacement.

Gelöst wird dieses technische Problem durch den Staubsauger mit den Merkmalen des vorliegenden Anspruchs 1. Vorteilhafte Weiterbildungen des erfindungsgemäßen Staubsaugers sind Gegenstand der abhängigen Ansprüche.This technical problem is solved by the vacuum cleaner with the features of the present claim 1.

Erfindungsgemäß kann der Handstaubsauger 12 über eine Batterieladegerät des den Bodenstaubsauger 11 mit elektrischer Energie aufgeladen werden. Das Prinzip der elektrischen Kopplung von Handstaubsauger 12 und Bodenstaubsauger 11 in der in Figur 1 dargestellten Position, also mit in die Ausnehmung 18 eingesetztem Handstaubsauger, wird im Folgenden insbesondere unter Bezugnahme auf die elektrischen Prinzipskizze der Figur 3 erläutert.According to the invention, the hand vacuum cleaner 12 can be charged via a battery charger of the vacuum cleaner 11 with electrical energy. The principle of the electrical coupling of hand vacuum cleaner 12 and vacuum cleaner 11 in the position shown in Figure 1, ie with inserted into the recess 18 hand vacuum cleaner is explained below in particular with reference to the electrical schematic diagram of Figure 3.

In der den Bodenstaubsauger 11 symbolisierenden Einheit sind der Netzstecker 16 und das Netzkabel 15 angedeutet, welche die insgesamt mit der Bezugsziffer 25 bezeichnete Stromversorgungseinrichtung des Hauptgehäuses 13 des Bodenstaubsaugers 11 über eine Eingangsnetzteil 26, welches gegebenenfalls einen Transformator umfasst, mit elektrischem Strom versorgt. Die Stromversorgungseinrichtung 25 umfasst eine Steuerungselektronik mit einer an sich bekannte Regelungs- und Antriebseinheit 27 für den nachgeschalteten Motor 28, die beispielsweise eine Leistungsregulierung des Bodenstaubsaugers ermöglicht. Über einen Schalter 29 wird der Bodenstaubsauger in Betrieb genommen.In the vacuum cleaner 11 symbolizing unit of the power plug 16 and the power cord 15 are indicated, which supplies the designated overall by the reference numeral 25 power supply of the main housing 13 of the vacuum cleaner 11 via an input power supply 26, which optionally includes a transformer with electric power. The power supply device 25 comprises a control electronics with a known control and drive unit 27 for the downstream motor 28, which allows, for example, a power regulation of the vacuum cleaner.

In der in Figur 3 den Handstaubsauger 12 symbolisierenden Einheit ist eine insgesamt mit der Bezugsziffer 30 bezeichnete Stromversorgungseinrichtung dargestellt. Die Stromversorgungseinrichtung 30 umfasst eine oder mehrere Batterien 31, die einen Gebläsemotor 32 Handstaubsaugers 12 antreiben. Dazu ist ein, in der Figur 3 in der AUS-Stellung dargestellter Schalter 33 vorgesehen, mit dem durch Umlegen auf einen AN-Kontakt 33a der Betriebsstromkreis 34 geschlossen und der Handstaubsauger 12 in Betrieb genommen werden kann.In the unit symbolizing the vacuum cleaner 12 in FIG. 3, a power supply device, indicated generally by the reference numeral 30, is shown. The power supply device 30 includes one or more batteries 31 that drive a blower motor 32 hand vacuum cleaner 12. For this purpose, a switch 33 shown in FIG. 3 in the OFF position is provided, with which the operating circuit 34 can be closed by transferring it to an ON contact 33a and the hand vacuum cleaner 12 can be put into operation.

Die im Gehäuseteil 20 des Handstaubsaugers 12 angeordneten Batterien 31 sind wiederaufladbar und können nach Einsetzen des Handstaubsaugers in die Ausnehmung 18 des Hauptgehäuses 13 des Bodenstaubsaugers 11 über die Stromversorgungseinrichtung 25 des Bodenstaubsaugers aufgeladen werden. Dazu weist die Stromversorgungseinrichtung 30 des Handstaubsaugers einen die wiederaufladbaren Batterien 31 enthaltenden Ladestromkreis 35 auf, der durch Umlegen des Schalters 33 auf einen LADE-Kontakt 33b aktiviert werden kann. Der Ladestromkreis 35 endet in zwei in die Unterseite des Gehäuseteil 20 mündende Ladeklemmen 36, 37.The arranged in the housing part 20 of the vacuum cleaner 12 batteries 31 are rechargeable and can be charged after insertion of the hand vacuum cleaner in the recess 18 of the main housing 13 of the vacuum cleaner 11 via the power supply device 25 of the vacuum cleaner. For this purpose, the power supply device 30 of the hand vacuum cleaner on a rechargeable batteries 31 containing charging circuit 35, which can be activated by turning the switch 33 to a LADE contact 33b. The charging circuit 35 terminates in two opening into the bottom of the housing part 20 load terminals 36, 37th

Zum Aufladen der Batterien 31 des Handstaubsaugers 12 weist die Stromversorgungseinrichtung 25 des Bodenstaubsaugers 11 ein Ladegerät 38 auf, welches über eine Verzweigung 39 aus dem Hauptstromkreis 40 des Bodenstaubsaugers gespeist wird. Das Ladegerät 38 weist Ladeklemmen 41, 42 auf, die im Boden der Ausnehmung 18 des Bodenstaubsaugers 11 enden. In der in Figur 1 dargestellten Position ist der Handstaubsauger 12 so in der Ausnehmung 18 angeordnet, dass sich die entsprechende, an der Unterseite des Gehäuseteils 20 des Handstaubsaugers 12 vorgesehene Ladeklemmen 36, 37 in elektrischem Kontakt mit den Ladeklemmen 41, 42 des Ladegeräts 26 des Bodenstaubsaugers 11 befinden. Wenn sich dann der Schalter 33 in der Ladestellung befindet und der Bodenstaubsauger 11 über den Stecker 16 am Stromnetzangeschlossen ist, können die Batterien 31 des Handstaubsaugers 12 aufgeladen werden. In der in der Figur 3 dargestellten Ausführungsform findet die Aufladung der Batterien 31 unabhängig von der Stellung des Schalters 29 statt, also unabhängig davon, ob der Bodenstaubsauger in Betrieb ist oder nicht. Der Ladestromkreis 35 weist außerdem eine Leuchtdiode 43 auf, durch die beim Aufladen der Batterien ein über Parallelwiderstände 44, 45 einstellbarer Strom fließt und dem Nutzer den Ladevorgang signalisiert. Als Ladegerät kann ein einfacher Wechselstrom/Gleichstromwandler eingesetzt werden, welcher die Batterien 31 mit konstantem Strom auflädt. Vorzugsweise wird aber ein sogenanntes intelligentes Ladegerät verwendet, welches über einen eingebauten Mikrokontroller eine Steuerung, Überwachung und Beendigung des Ladevorgangs erlaubt. Damit lassen sich auch aufwändigere Ladeverfahren realisieren, wie zum Beispiel die Ladung des Akkumulators mittels Stromimpulsen. So kann man beispielsweise eine Erkennung der Vollladung der Batterien 31 und damit eine sichere Schnellladung ohne Gefahr von schädlicher Überladung realisieren. Ebenso kann bei Bedarf ein automatische Entladung der wiederaufladbaren Batterien oder ein automatisches Umschalten auf Erhaltungsladung nach Beendigung das eigentlichen Ladevorgangs realisiert werden. Ebenso kann eine (hier nicht dargestellte) Anzeigeeinrichtung auf dem Handstaubsauger 12 vorgesehen sein, welche den Ladezustand der Batterien 31 signalisiert.For charging the batteries 31 of the hand vacuum cleaner 12, the power supply device 25 of the vacuum cleaner 11, a charger 38, which is fed via a branch 39 from the main circuit 40 of the vacuum cleaner. The charger 38 has charging terminals 41, 42 which terminate in the bottom of the recess 18 of the vacuum cleaner 11. In the position shown in Figure 1, the hand vacuum cleaner 12 is disposed in the recess 18 that the corresponding, provided on the underside of the housing part 20 of the hand vacuum cleaner 12 charging terminals 36, 37 in electrical contact with the charging terminals 41, 42 of the charger 26 of the Canister 11 are located. Then, when the switch 33 is in the loading position and the canister vacuum cleaner 11 is connected to the power supply via the plug 16, the batteries 31 of the hand vacuum cleaner 12 can be charged. In the embodiment shown in Figure 3, the charging of the batteries 31 takes place regardless of the position of the switch 29, that is, regardless of whether the vacuum cleaner is in operation or not. The charging circuit 35 also has a light-emitting diode 43, through which a current that can be set via parallel resistors 44, 45 flows when charging the batteries and signals the charging process to the user. As a charger, a simple AC / DC converter can be used, which charges the batteries 31 with a constant current. Preferably, however, a so-called smart charger is used, which allows a built-in microcontroller control, monitoring and termination of the charging process. This can also be realized more complex charging methods, such as the charge of the battery by means of current pulses. So you can, for example, realize a detection of the full charge of the batteries 31 and thus a safe fast charge without the risk of harmful overload. Also, if necessary, an automatic discharge of the rechargeable batteries or an automatic switch to trickle charge after completion of the actual charging process can be realized. Likewise, a (not shown here) display device may be provided on the hand vacuum cleaner 12, which signals the state of charge of the batteries 31.
