Description

Die Erfindung betrifft einen Staubsauger mit einem Saugvorsatz und mit einem Handgriff, wobei zur Führung des Saugvorsatzes mittels des Handgriffs zwischen diesen ein Stiel und/oder ein Saugrohr und/oder ein Saugaggregat angeordnet ist, und mit einer Beleuchtungseinrichtung zum Ausleuchten des Arbeitsbereichs vor dem Saugvorsatz.The invention relates to a vacuum cleaner with a suction attachment and with a handle, wherein a handle and / or a suction tube and / or a suction unit is arranged to guide the suction attachment by means of the handle between them and with a lighting device for illuminating the working area in front of the suction attachment.

Beim Saugen in Nischen, unter Tischen oder in anderen dunkleren Ecken besteht das Problem, dass der Saugbereich hier sehr schlecht einzusehen ist.When sucking in niches, under tables or in other darker corners, there is the problem that the suction area is very difficult to see here.

Staubsauger mit Beleuchtungseinrichtungen sind allgemein bekannt. Dabei ist eine Lampe in dem Saugvorsatz angeordnet, siehe beispielsweise DE 103 53 456 A1 . Die Lampe wird mit dem Einschalten der Versorgungsspannung des Staubsaugers und dem damit einhergehenden Einschalten des Sauggebläses aktiviert und bleibt dies für den gesamten Saugbetrieb. Dies ist jedoch nicht immer nötig und verursacht deshalb einen zu hohen Energieverbrauch. Sollte die Lampe mit einer separaten Schalteinrichtung versehen werden, müsste entweder ein nur schwer erreichbarer Schalter an dem Saugvorsatz angeordnet sein oder es müsste eine zusätzliche Leitung in einen besser erreichbaren Bereich verlegt werden. Im Übrigen ist eine Ausleuchtung des Saugbereichs nur dann möglich, wenn der Staubsauger mit der entsprechenden Saugeinheit ausgestattet ist.Vacuum cleaners with lighting equipment are well known. In this case, a lamp is arranged in the suction attachment, see for example DE 103 53 456 A1 , The lamp is activated by switching on the supply voltage of the vacuum cleaner and the associated switching on the suction fan and this remains for the entire suction operation. However, this is not always necessary and therefore causes too high an energy consumption. Should the lamp be provided with a separate switching device, either a difficult-to-reach switch would have to be arranged on the suction attachment or an additional line would have to be laid in a more accessible area. Incidentally, an illumination of the suction area is only possible if the vacuum cleaner is equipped with the corresponding suction unit.

Aus der DE 20 220 003 U1 ist ein Staubsauger bekannt, bei dem eine Lampe mittels eines Halteclips auf das Saugrohr gesteckt ist. Die Lampe wird über ein freiliegendes Kabel vom Staubsauger mit Strom versorgt.From the DE 20 220 003 U1 a vacuum cleaner is known in which a lamp is inserted by means of a retaining clip on the suction pipe. The lamp is powered by an exposed cable from the vacuum cleaner.

Aus der WO 2006/029535 A1 ist ein Staubsaugerhandgriff mit einer Beleuchtungseinrichtung bekannt. Auch dort erfolgt die Stromversorgung und Ansteuerung vom zentralen Saugaggregat.From the WO 2006/029535 A1 is a vacuum cleaner handle with a lighting device known. Also there, the power supply and control of the central suction unit.

Die DE 202 02 690 U1 offenbart einen Staubsauger, der als sogenannter Tischstaubsauger oder Fahrzeugstaubsauger ausgebildet ist. Bei diesem ist eine Beleuchtungseinrichtung an einem hinteren Abschnitt des Hauptgehäuses angeordnet. Sie ist insofern nicht in der Lage, den Arbeitsbereich vor dem Saugvorsatz auszuleuchten. Der Einschaltknopf der Beleuchtung ist an einem Handgriff angeordnet.The DE 202 02 690 U1 discloses a vacuum cleaner, which is designed as a so-called table vacuum cleaner or vehicle vacuum cleaner. In this, a lighting device is arranged at a rear portion of the main housing. It is therefore unable to illuminate the work area in front of the suction attachment. The power button of the lighting is arranged on a handle.

Der Erfindung stellt sich somit das Problem, einen Staubsauger der eingangs genannten Art zu offenbaren, bei dem die Beleuchtungseinrichtung bei einfacher Handhabbarkeit energiesparend und einfach aufgebaut ist.The invention thus raises the problem of disclosing a vacuum cleaner of the type mentioned, in which the lighting device with simple handling energy-saving and simple design.

Erfindungsgemäß wird dieses Problem durch einen Staubsauger mit den Merkmalen desAccording to the invention, this problem is solved by a vacuum cleaner with the features of

Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.Patent claim 1 solved. Advantageous embodiments and further developments of the invention will become apparent from the following subclaims.

Die mit der Erfindung erreichbaren Vorteile ergeben sich daraus, dass die Beleuchtungseinrichtung in dem Handgriff angeordnet ist und dass in oder an dem Handgriff ein Aufnahmefach für mindestens einen Akkumulator oder mindestens eine Batterie zur Energieversorgung der Beleuchtungseinrichtung und eine Bedieneinrichtung zum Einund/oder Ausschalten der Beleuchtungseinrichtung angeordnet ist. Hierdurch ist der Handgriff mit einer autarken Beleuchtungseinrichtung ausgestattet, die unabhängig von einem Basisgerät und nur dann, wenn es der Bediener wünscht, betrieben werden kann.The achievable with the invention advantages result from the fact that the illumination device is arranged in the handle and that arranged in or on the handle a receptacle for at least one accumulator or at least one battery for powering the illumination device and an operating device for switching on and / off the illumination device is. As a result, the handle is equipped with a self-sufficient lighting device that can be operated independently of a base unit and only if the operator desires.

In einer vorteilhaften Ausführungsform ist die Bedieneinrichtung als Taster ausgebildet. Dadurch wird dem Benutzer das "Eingeschaltet sein" der Beleuchtung bewusst gemacht. Dabei ist es besonders vorteilhaft, wenn dem Taster eine Schalteinrichtung zugeordnet ist, welche nach dem Loslassen des Tasters die Beleuchtungseinrichtung für einen vorgegebenen Zeitraum eingeschaltet hält. Für kurze Einschaltzeiten reicht dann ein einmaliger Druck auf den Taster, bei längeren Zeiten erfolgt ein gewisses Nachleuchten mit einem langsamen Erlöschen.In an advantageous embodiment, the operating device is designed as a button. This will make the user aware of the "being turned on" lighting. It is particularly advantageous if the switch is associated with a switching device which keeps the lighting device turned on for a predetermined period after releasing the button. For short switch-on times, a single press on the button is sufficient; for longer periods, a certain afterglow occurs with a slow extinction.

Eine langlebige und energiesparende Beleuchtung wird durch die Verwendung mindestens einer Leuchtdiode erreicht. Dabei ist es vorteilhaft, wenn eine Treiberschaltung eingesetzt wird, mit welcher die Leuchtdiode auch bei nachlassender Zellenspannung der Batterie oder des Akkumulators mit einem konstanten Strom betrieben wird. Hierdurch wird eine gleichbleibende Beleuchtungsstärke erreicht.A long-lasting and energy-saving lighting is achieved by the use of at least one light-emitting diode. It is advantageous if a driver circuit is used, with which the light-emitting diode is operated even with decreasing cell voltage of the battery or the accumulator with a constant current. As a result, a constant illuminance is achieved.

Um eine gute Ausleuchtung des zu saugenden Bereichs vor dem Saugvorsatz zu ermöglichen, ist der Beleuchtungseinrichtung eine optische Einrichtung zugeordnet, welche einen in den Bodenbereich vor dem Saugvorsatz gerichteten Lichtkegel erzeugt.In order to enable a good illumination of the region to be sucked in front of the suction attachment, the illumination device is assigned an optical device which generates a light cone directed into the bottom region in front of the suction attachment.

Die beanspruchte Beleuchtungseinrichtung wird in bevorzugter Weise bei einem Bodenstaubsauger eingesetzt, welcher mit einem zwischen dem Saugvorsatz und dem Handgriff angeordneten Saugrohr ausgebildet ist.The claimed lighting device is preferably used in a vacuum cleaner, which is formed with a suction pipe arranged between the suction and the suction pipe.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen rein schematisch dargestellt und wird nachfolgend näher beschrieben. Es zeigen:

Figur 1
einen betriebsbereiten Bodenstaubsauger,
Figur 2 bis 4
den Handgriff des Bodenstaubsaugers in verschiedenen Darstellungen.
  • In Figur 1 ist ein betriebsbereiter Bodenstaubsauger 1 dargestellt. Er besitzt ein Basisgehäuse 2, an welches über einen Saugschlauch 3, einen Handgriff 4 und ein Saugrohr 5, ein Saugvorsatz 6, hier in Form einer einfachen Bodendüse, angeschlossen ist. Die Bodendüse 6 löst den auf dem Boden 7 befindlichen Schmutz. Dieser wird dann zusammen mit der angesaugten Luft über das Saugrohr 5 und den Saugschlauch 3 ins Innere des Basisgehäuses 2 geleitet. Dort wird in bekannter Weise der Schmutz wieder aus der angesaugten Luft ausgefiltert. Der Handgriff 4 dient einerseits zur Verbindung von Saugrohr 5 und Saugschlauch 3,
  • andererseits ist er zum Führen und Lenken des Saugvorsatzes 6 über den zu bearbeitenden Boden 7 vorgesehen. Wie in der Figur 1 erkennbar ist, ist in dem Handgriff 4 eine Beleuchtungseinrichtung 8 eingebaut, mit der der Bediener beim Gebrauch des Staubsaugers 1 in der beschriebenen Anordnung einen Arbeitsbereich 9 vor dem Saugvorsatz 6 ausleuchten kann.
An embodiment of the invention is shown purely schematically in the drawings and will be described in more detail below. Show it:
FIG. 1
an operational canister vacuum cleaner,
FIGS. 2 to 4
the handle of the vacuum cleaner in different representations.
  • In FIG. 1 an operable vacuum cleaner 1 is shown. It has a base housing 2 to which a suction hose 3, a handle 4 and a suction tube 5, a suction attachment 6, here in the form of a simple floor nozzle, is connected. The floor nozzle 6 dissolves the dirt located on the floor 7. This is then passed together with the sucked air through the suction pipe 5 and the suction hose 3 into the interior of the base housing 2. There, the dirt is filtered out of the sucked air in a known manner. The handle 4 serves on the one hand to connect the suction tube 5 and suction hose 3,
  • On the other hand, it is provided for guiding and guiding the suction attachment 6 over the soil 7 to be processed. Like in the FIG. 1 can be seen, in the handle 4, a lighting device 8 is installed with which the operator can illuminate a work area 9 in front of the suction attachment 6 when using the vacuum cleaner 1 in the described arrangement.

Die Figuren 2 bis 4 zeigen den Handgriff 4 als Einzelheit, wobei er in Figur 2 perspektivisch, in der Figur 3 in einem Längsschnitt und in der Figur 4 in einer Explosionsdarstellung gezeigt ist. Der Handgriff 4 besteht im Wesentlichen aus einem Griffteil 41, einem Schlauchanschlussstutzen 42 und einem Rohranschlussstutzen 43. Der Schlauchanschlussstutzen 42 ist drehbar an dem Griffteil 41 gelagert, er nimmt den Saugschlauch 3 mittels einer nicht dargestellten Rastverbindung auf. Der Rohranschlussstutzen 43 ist drehfest mit dem Griffteil 41 verbunden. Auch er besitzt eine Rastaufnahme 44, mittels der das Saugrohr 5 an dem Handgriff befestigt werden kann. Das Griffteil 41 besitzt ein Außengehäuse, welches aus einem Griffoberteil 45, einem Griffunterteil 46 und einer Abdeckung 47 besteht. In die Abdeckung sind eine transparente Scheibe 48 und ein Deckel 49 eingesetzt, oberhalb des Deckels 49 ist ein Bedienknopf 80 angeordnet.The FIGS. 2 to 4 show the handle 4 as a detail, being in FIG. 2 in perspective, in the FIG. 3 in a longitudinal section and in the FIG. 4 is shown in an exploded view. The handle 4 consists essentially of a handle portion 41, a hose connection piece 42 and a pipe connection piece 43. The hose connection piece 42 is rotatably mounted on the handle portion 41, he takes the suction hose 3 by means of a locking connection, not shown. The pipe connection piece 43 is rotatably connected to the handle part 41. He also has a locking receptacle 44, by means of which the suction tube 5 can be attached to the handle. The handle part 41 has an outer housing which consists of a handle upper part 45, a handle bottom part 46 and a cover 47. In the cover, a transparent disc 48 and a lid 49 are used, above the lid 49, a control knob 80 is arranged.

Die Beleuchtungseinrichtung 8 ist unter der Abdeckung 47 angeordnet. Die Lampe selbst ist als Leuchtdiode 81 ausgeführt und auf einer Platine 82 angeordnet. Auf dieser Platine 82 befinden sich auch eine Schalteinrichtung 83 und eine Treiberschaltung 84, deren Funktion später erklärt ist. Die Platine 82 besitzt einen rechteckigen Ausschnitt 85, in den eine Aufnahmetrommel 86 für drei 1,5 Volt AAA Batterien oder entsprechende Akkumulatoren (beides nicht dargestellt) eingesetzt ist. Diese liefern die Stromversorgung für die Leuchtdiode 81 über die vorgenannten Schaltungen 83 und 84. Die Trommel 86 ist nach Entfernung des Deckels 49 entnehmbar, so dass Batterien oder Akkumulatoren ausgetauscht werden können. Vor der Leuchtdiode 81 ist eine Linse 87 angeordnet, welche das ausgestrahlte Licht bündelt und durch die transparente Scheibe 48 auf die Position vor dem Saugvorsatz 6 richtet. Die Linse 87 wird durch eine Linsenaufnahme 88 gehalten.The lighting device 8 is arranged under the cover 47. The lamp itself is designed as a light-emitting diode 81 and arranged on a circuit board 82. On this board 82 are also a switching device 83 and a driver circuit 84, whose function will be explained later. The board 82 has a rectangular cutout 85, in which a receiving drum 86 for three 1.5 volt AAA batteries or corresponding accumulators (both not shown) is used. These supply the power supply for the light-emitting diode 81 via the aforementioned circuits 83 and 84. The drum 86 can be removed after removal of the cover 49, so that batteries or accumulators can be exchanged. In front of the light-emitting diode 81, a lens 87 is arranged which focuses the emitted light and directs it through the transparent pane 48 to the position in front of the suction attachment 6. The lens 87 is held by a lens holder 88.

Der Bedienknopf 80 ist als nichtrastender Taster ausgebildet. Durch Drücken erfolgt die Stromzufuhr zur Leuchtdiode 81. Dabei sorgt die Schalteinrichtung 83 dafür, dass nach demThe control knob 80 is designed as a non-latching button. By pressing the power supply to the light emitting diode 81. In this case, the switching device 83 ensures that after the

Loslassen des Tasters 80 die Leuchtdiode 81 für einen vorgegebenen Zeitraum eingeschaltet bleibt. Der Bediener hat somit zwei Optionen. Ein kurzer Tastendruck startet eine Zeitschaltung der Schalteinrichtung 83. Das Licht der Leuchtdiode 81 leuchtet dann für ca. 15-30 Sekunden, je nach Dimensionierung der Zeitschaltung und erlischt dann langsam. Ein länger dauernder Tastendruck ergibt ein Dauerlicht, nach Loslassen des Tasters bleibt die von der Schalteinrichtung 83 per Zeitschaltung gesteuerte Nachleuchtzeit mit langsamem Erlöschen. Die Treiberschaltung 84 hält die Stromzufuhr zur Leuchtdiode 81 und damit deren Helligkeit konstant, bis die Zellenspannung der Batterien auf 0,9 Volt pro Zelle abgesunken ist. Durch die Treiberschaltung 84 wird somit auch gewährleistet, dass bei der Verwendung von Akkumulatoren, die üblicherweise nur eine Spannung von 1,2 Volt besitzen, die Leuchtdiode 81 mit der gleichen Helligkeit wie bei der Verwendung von Batterien strahlt. Hierdurch ergibt sich eine gute Ausnutzung der Energiequellen.Release the button 80, the LED 81 remains on for a predetermined period of time. The operator thus has two options. A short keystroke starts a timer of the switching device 83. The light of the LED 81 then lights for about 15-30 seconds, depending on the size of the timer and then goes out slowly. A prolonged pressing the button results in a steady light, after releasing the button remains controlled by the switching device 83 by timer persistence with slow extinction. The driver circuit 84 keeps the power supply to the LED 81 and thus its brightness constant until the cell voltage of the batteries has dropped to 0.9 volts per cell. By the driver circuit 84 is thus also ensured that when using batteries that usually have only a voltage of 1.2 volts, the light emitting diode 81 radiates with the same brightness as when using batteries. This results in a good utilization of energy sources.
