Description
Staubsauger vacuum cleaner
Die Erfindung bezieht sich auf einen Staubsauger, mit einem Laufrollen aufweisenden Fahrwerk, welches am Staubsaugergehäuse angeordnet ist, an dem weiterhin eine Saugöffnung zur Lagerung eines zumindest drehbaren Saugstutzen angeordnet ist, der mit dem dem Staubsaugergehäuse zugeordneten Endbereich eines Saugschlauches verbunden ist.The invention relates to a vacuum cleaner, with a running gear having casters, which is arranged on the vacuum cleaner housing, on which further a suction opening for supporting an at least rotatable suction nozzle is arranged, which is connected to the vacuum cleaner housing associated end portion of a suction hose.
Bei dem in Rede stehenden Staubsauger handelt es sich in bevorzugter Ausführung um einen sogenannten Bodenstaubsauger, der in einem Haushalt Verwendung findet und mit dem unter anderem Bodenflächen gereinigt werden. Das Fahrwerk besteht üblicherweise aus drei Laufrollen, von denen zwei auf einer Achse frei drehbar gelagert sind. Beim Reinigungsvorgang folgt der Staubsauger der den Staubsauger führenden Person in dem diese den Staubsauger hinter sich herzieht. Dazu ist das Fahrwerk noch mit einer um eine vertikale Achse schwenkbare Lenkrolle versehen. Das Ziehen des Staubsaugers erfolgt, indem der Saugschlauch gespannt wird und somit eine Zugkraft auf den Staubsauger ausübt.The vacuum cleaner in question is in a preferred embodiment a so-called vacuum cleaner, which is used in a household and are cleaned with the floor surfaces, among other things. The chassis usually consists of three rollers, two of which are freely rotatably mounted on an axle. During the cleaning process, the vacuum cleaner follows the person leading the vacuum cleaner by pulling the vacuum cleaner behind him. For this purpose, the chassis is still provided with a pivotable about a vertical axis steering roller. The pulling of the vacuum cleaner takes place by the suction hose is tensioned and thus exerts a pulling force on the vacuum cleaner.
Der zuvor beschriebene Staubsauger hat sich bestens bewährt. Es wird jedoch als Nachteil empfunden, dass die den Staubsauger führende Person diesen hinter sich herbewegen muss, wenn sichergestellt sein soll, dass der Saugschlauch nicht gespannt werden soll.The vacuum cleaner described above has proven itself very well. However, it is perceived as a disadvantage that the person leading the vacuum cleaner has to move this behind him, if it is to be ensured that the suction hose is not to be tensioned.
Der Erfindung liegt die Aufgabe zugrunde, einen Staubsauger der eingangs näher beschriebenen Art so zu gestalten, dass der Bedienkomfort erhöht wird, indem sichergestellt ist, dass der Staubsauger sinngemäß der den Staubsauger führenden Person selbsttätig folgt.The invention has for its object to make a vacuum cleaner of the type described in more detail so that the ease of use is increased by ensuring that the vacuum cleaner mutatis mutandis follows the person leading the vacuum cleaner.
Die gestellte Aufgabe wird gelöst, indem die den Anschluss für den Saugstutzen bildende Saugöffnung und/oder der Saugstutzen derart gestaltet sind, dass der Saugstutzen zusätzlich zu seiner Drehbewegung relativ bewegbar ist und dass mindestens ein durch die zusätzliche Relativbewegung aktivierbarer Signalgeber zur Erzeugung elektrischer Steuersignale vorgesehen ist, die in eine Steuereinheit einspeisbar sind, und dass bestimmte Laufrollen des Fahrwerkes hinsichtlich ihrer Fahrrichtung durch von der Steuereinheit umgesetzte Signale ansteuerbar sind.This object is achieved by the suction port forming the connection for the suction nozzle and / or the suction nozzle are designed such that the suction nozzle is relatively movable in addition to its rotational movement and that at least one by the additional relative movement activatable signal generator for generating electrical control signals is provided , which are fed into a control unit, and that certain wheels of the chassis are controlled in terms of their direction of travel by converted by the control unit signals.
Die Verbindung bzw. die Lagerung des Saugstutzens innerhalb der Saugöffnung ist nunmehr so gestaltet, dass der Saugstutzen eine dreidimensionale Bewegung ausführen kann, d.h. er ist in entgegengesetzten Richtungen drehbar und kann zusätzlich eine weitere Bewegung ausführen. Diese weitere Bewegung wird dann genutzt, um den Signalgeber zu aktivieren, so dass diese Signale nach einer entsprechenden Verarbeitung als Steuersignale für die die Laufrollen antreibenden Motoren umgesetzt werden. Da das Fahrwerk nunmehr mit einzeln antreibbaren Laufrollen ausgestattet ist, werden durch die Aktivierung des Signalgebers entweder sämtliche Antriebsmotoren eingeschaltet oder es wird nur ein Antriebsmotor eingeschaltet oder die Antriebsmotoren werden mit unterschiedlichen Drehzahlen angetrieben, so dass der Staubsauger selbsttätig entweder geradeaus oder auch eine Kurve fährt. Durch die Aktivierung s des Signalgebers werden demzufolge nicht nur Ein- und Ausschaltsignale erzeugt, sondern darüber hinaus auch Richtungssignale. Bei der erfindungsgemäßen Lösung bildet der Saugschlauch in Verbindung mit dem Saugstutzen sinngemäß einen mechanischen Signalgeber. Wenn die Aktionsweite des Saugschlauches infolge der festgelegten Länge beim Saugen ausgeschöpft ist, spannt sich der Schlauch und die aufgebaute Zugkraft wird auf denThe connection or storage of the suction within the suction opening is now designed so that the suction can perform a three-dimensional movement, ie it is rotatable in opposite directions and can additionally perform a further movement. This further movement is then used to activate the signal generator, so that these signals are converted after appropriate processing as control signals for the rollers driving the motors. Since the chassis now with individually driven Equipped casters are activated by the activation of the signal generator either all the drive motors or it is only one drive motor is switched on or the drive motors are driven at different speeds, so that the vacuum cleaner either straightforward or even a curve. As a result of the activation of the signal generator, not only are switching-on and switch-off signals generated, but also directional signals. In the solution according to the invention, the suction hose in conjunction with the suction nozzle mutatis mutandis forms a mechanical signal generator. If the range of action of the suction hose is exhausted due to the specified length during suction, the hose tensioned and the traction force is built on the
10 Saugstutzen übertragen. Infolge dieser Zugkraft entsteht dann die zusätzliche Bewegung relativ zu der möglichen Drehbewegung. Es erfolgt demzufolge eine Kräfteverteilung in der Lagerung des Saugstutzens.10 transfer suction. As a result of this tensile force then arises the additional movement relative to the possible rotational movement. There is consequently a distribution of forces in the storage of the suction nozzle.
In einer bevorzugten Ausführung ist vorgesehen, dass die Lagerung des Saugstutzens innerhalb der Saugöffnung als Gelenklager ausgebildet ist. Dadurch kann der Saugstutzen i5 zusätzlich zur Drehbewegung in entgegengesetzten Richtungen eine Kippbewegung ausführen. Der Saugstutzen kann diese Kippbewegung innerhalb des Drehwinkels in jeder Stellung ausführen.In a preferred embodiment it is provided that the storage of the suction nozzle is formed within the suction opening as a joint bearing. This allows the suction nozzle i 5 perform in addition to the rotational movement in opposite directions a tilting movement. The suction nozzle can perform this tilting movement within the rotation angle in any position.
Eine konstruktiv einfache Lösung ist gegeben, wenn das Gelenklager aus einer in die Saugöffnung eingesetzten sowie den Saugstutzen aufnehmenden Buchse gebildet ist. DieseA structurally simple solution is given when the joint bearing is formed from a used in the suction opening and the suction nozzle receiving socket. These
20 Buchse kann dann innerhalb der Saugöffnung verdreht werden und gleichzeitig die zusätzliche Kippbewegung ausführen. Diese Beweglichkeit der Buchse lässt sich in einfachster Weise erreichen, wenn die Außenkontur der Buchse ballig, als Kugelabschnitt oder dergleichen ausgebildet ist, und dass die Saugöffnung an die Außenkontur der Buchse angepasst ist, und dass der Passsitz zwischen der Buchse und der Saugöffnung als Spielpassung ausgebildet ist.20 socket can then be rotated within the suction opening and at the same time perform the additional tilting movement. This mobility of the sleeve can be achieved in the simplest manner, when the outer contour of the sleeve is spherical, designed as a ball portion or the like, and that the suction port is adapted to the outer contour of the socket, and that the fit between the sleeve and the suction port formed as a clearance is.
25 Das sich daraus ergebende Spiel bzw. das Übermaß der Saugöffnung gegenüber der Außenkontur der Buchse erlaubt es, dass die Buchse äußerst leichtgängig innerhalb der Saugöffnung bewegbar ist. Dadurch ist eine äußerst geringe Zugkraft notwendig, um die Bewegung zur Aktivierung des Signalgebers auszulösen. Darüber hinaus ist das Spiel der Spielpassung nur so groß, dass dieser Passsitz als spielfrei angesehen werden kann, so dassThe resulting play or the excess of the suction opening with respect to the outer contour of the bushing allows the bushing to be moved extremely smoothly within the suction opening. As a result, an extremely low tensile force is necessary to trigger the movement to activate the signal generator. In addition, the game of the game fit is only so great that this fit can be considered free of play, so that
30 es nicht zum Klappern oder ähnlichen Geräuschen kommen kann.30 it can not come to rattle or similar noise.
Es ist ferner vorgesehen, dass an der Außenseite der Buchse mehrere im Winkelabstand zueinander stehende, nutartige Ausnehmungen vorgesehen sind, die sich in Richtung der Drehachse der Buchse erstrecken. Dadurch wird erreicht, dass der Saugstutzen innerhalb seiner Lagerung automatisch zurückfedert, wenn die von dem Saugschlauch aufgebrachten 35 Zugkräfte abgebaut sind. Dadurch werden keine zusätzlichen Federelemente benötigt, die die Rückstellkraft aufbauen. In einer bevorzugten Ausführung ist vorgesehen, dass an der Außenseite der Buchse vier Ausnehmungen vorgesehen sind, die jeweils um 90° zueinander im Versatz stehen.It is further provided that a plurality of angularly spaced, groove-like recesses are provided on the outside of the sleeve, which extend in the direction of the axis of rotation of the sleeve. This ensures that the suction nozzle springs back automatically within its storage, when the applied by the suction hose 3 5 tensile forces are reduced. As a result, no additional spring elements are required, which build up the restoring force. In a preferred embodiment it is provided that at the Outside of the bush four recesses are provided, which are each offset by 90 ° to each other.
Damit die von dem Signalgeber in die Steuereinheit eingespeisten Signale funktionsgerecht umgesetzt werden können, d.h. in Schaltsignale für die Antriebsmotoren und in zusätzliche Richtungssignale, ist vorgesehen, dass die Buchse an der dem Saugstutzen zugewandten Seite einen Flansch aufweist, und dass im Staubsaugergehäuse mehrere im Abstand zueinander angeordnete Endschalter montiert sind, die eine Endlagenabfrageeinheit bilden. Diese Endlagenabfrageeinheit kann elektromechanisch oder elektronisch ausgelegt sein. Je nachdem, welcher Endschalter bei einer auf den Saugstutzen wirkenden Zugkraft betätigt wird, werden durch die Steuereinheit die entsprechenden Schaltungen der Antriebsmotoren ausgelöst. Dabei ist vorgesehen, dass die Endschalter auf einem konzentrisch zur Drehachse der Buchse verlaufenden Kreisbogen montiert sind.In order that the signals fed into the control unit from the signal generator can be functionally converted, i. in switching signals for the drive motors and in additional directional signals, it is provided that the bush has a flange on the side facing the suction nozzle, and that a plurality of mutually spaced limit switches are mounted in the vacuum cleaner housing, which form a Endlagenabfrageeinheit. This Endlagenabfrageeinheit can be designed electromechanically or electronically. Depending on which limit switch is actuated in a pulling force acting on the suction nozzle, the corresponding circuits of the drive motors are triggered by the control unit. It is provided that the limit switches are mounted on a concentric with the axis of rotation of the sleeve extending arc.
Zur Auslösung der die Richtung des Staubsaugers bestimmenden Signale ist vorgesehen, dass dem Gelenklager mindestens zwei nach dem Reflexionsverfahren arbeitende Lichtschranken zugeordnet sind. Diese Lichtschranken arbeiten nach dem allgemeinen optischen Prinzip und es ist vorgesehen, dass jede als Sender arbeitende Lichtschranke außenseitig an der Buchse angeordnet ist und der Empfänger in der das Gegenlager bildenden Saugöffnung des Staubsaugergehäuses angeordnet ist. Aufgrund dieser vorteilhaften Ausführung der Buchse und des Gegenlagers in Form der Saugöffnung in Verbindung mit dem Saugstutzen erfolgt darüber hinaus gleichzeitig eine Entkopplung des Systems von der staubbeladenen Luft.To trigger the signals of the direction of the vacuum cleaner, it is provided that at least two light barriers operating according to the reflection method are associated with the spherical plain bearing. These photocells work on the general optical principle and it is envisaged that each photocell operating as a transmitter is arranged on the outside of the socket and the receiver is arranged in the suction bearing forming the abutment of the vacuum cleaner housing. Due to this advantageous embodiment of the bushing and the thrust bearing in the form of the suction port in connection with the suction nozzle also takes place beyond a decoupling of the system from the dust-laden air.
Es ist in weiterer Ausgestaltung noch vorgesehen, dass die Endlagenabfrageeinheit nach digitaler oder analoger Arbeitsweise ausgelegt ist. Die Übermittlung der Einschalt- und Richtungssignale kann auf verschiedene Art und Weise erfolgen. So ist vorgesehen, dass diese über Leitungen oder Kabel oder drahtlos beispielsweise durch Funksignale, Infrarotsignale und ähnliche Signale übertragbar sind. Die drahtlose Übertragung bietet den Vorteil, dass auf entsprechende Leitungen verzichtet werden kann.It is also provided in a further embodiment that the Endlagenabfrageeinheit is designed for digital or analog operation. The transmission of the turn-on and direction signals can be done in various ways. It is envisaged that these can be transmitted via lines or cables or wirelessly, for example, by radio signals, infrared signals and similar signals. The wireless transmission has the advantage that it can be dispensed with corresponding lines.
Bei dem erfindungsgemäßen Staubsauger ist aus dem Saugstutzen, der in die Saugöffnung eingesetzten Buchse und der Endlagenabfrageeinheit eine Sensoreinheit gebildet, um die Antriebsmotoren der Laufrollen bzw. Laufräder anzusteuern.In the vacuum cleaner according to the invention, a sensor unit is formed from the suction nozzle, the socket inserted into the suction opening and the Endlagenabfrageeinheit to control the drive motors of the rollers or wheels.
Es ist ferner noch vorgesehen, dass die Steuerschaltung der Steuereinheit eineIt is further provided that the control circuit of the control unit a
Steuerelektronik mit einem Mikrocontroller enthält, und dass die Steuerschaltung darüber hinaus eine der Anzahl der Antriebsmotoren entsprechende Stückzahl von Leistungsschaltern enthält. In bevorzugter Weise werden zwei auf eine gemeinsame Achse aufgesetzte Laufrollen angetrieben. Die Laufrollen sind dann für sich gesehen frei drehbar gelagert, so dass auch der Staubsauger von Hand gezogen werden kann. Jedem Antriebsmotor ist dabei ein Leistungsschalter zugeordnet. Erkennt der Mikrocontroller die Einschalt- und Richtungsinformation, aktiviert er über die Leistungsschalter die Antriebsmotoren. Wenn die beiden Antriebsmotoren mit unterschiedlich hohen Spannungen beaufschlagt werden, schwenkt der Staubsauger bzw. es wird ein Kurve gefahren. Sind die Spannungen gleich, wird eine 5 geradlinige Fahrrichtung beibehalten.Contains control electronics with a microcontroller, and that the control circuit also contains a number of power switches corresponding to the number of drive motors. Preferably, two rollers mounted on a common axis are driven. The rollers are then seen to be freely rotatably mounted, so that the vacuum cleaner can be pulled by hand. Each drive motor is one Circuit breaker assigned. If the microcontroller detects the switch-on and direction information, it activates the drive motors via the circuit-breakers. If the two drive motors are subjected to different voltages, the vacuum cleaner swings or a turn is made. If the voltages are equal, a straight travel direction is maintained.

Der in der Figur 1 dargestellte Staubsauger 1 ist als Bodenstaubsauger ausgerüstet, der mit 0 einem Fahrwerk ausgerüstet ist, welches aus zwei seitlich neben dem Gehäuse 2 auf einer Achse gelagerten hinteren Laufrollen 3 und einer vorderen Lenkrolle 4 (s. Figur 6) gebildet ist. In dem Gehäuse 2 sind ferner die Funktionsteile des Staubsaugers montiert. An dem Gehäuse 2 ist ein Staubraumdeckel 6 um eine zur Achse der Laufrollen 3 achsparallele Achse schwenkbar. In der Figur 1 ist der Staubraumdeckel 6 in seiner Offenstellung gezeigt. Der s Staubraumdeckel 6 ist mit einer Saugöffnung 7 versehen (Figur 2), in die in noch näher erläuterter Weise ein Saugstutzen 8 dreh- und kippbar gelagert ist. An dem Saugstutzen 8 ist ein dehnfähiger Saugschlauch 9 angeschlossen, dessen anderes Ende zu einem teleskopierbaren Saugrohr 10 führt. Der Verbindungsbereich zwischen dem teleskopierbaren Saugrohr 10 und dem Saugschlauch 9 ist als Handhabe 1 1 ausgebildet. Auf das freie Ende des 30 teleskopierbaren Saugrohres 10 ist eine Saugbürste 12 aufgesteckt.The vacuum cleaner 1 shown in Figure 1 is equipped as a vacuum cleaner, which is equipped with a chassis 0, which is formed of two laterally adjacent to the housing 2 on an axle rear wheels 3 and a front castor 4 (see Figure 6). In the housing 2, the functional parts of the vacuum cleaner are also mounted. On the housing 2, a dust chamber cover 6 is pivotable about an axis axially parallel to the axis of the rollers 3. In the figure 1, the dust chamber cover 6 is shown in its open position. The s dust chamber cover 6 is provided with a suction opening 7 (Figure 2), in the manner explained in more detail, a suction nozzle 8 is rotatably mounted and tilted. At the suction nozzle 8, a stretchable suction hose 9 is connected, the other end leads to a telescopic suction tube 10. The connection region between the telescopic suction tube 10 and the suction hose 9 is formed as a handle 1 1. On the free end of the telescopic suction tube 10 30 a suction brush 12 is attached.
Die Figur 2 zeigt, dass das dem Gehäuse 2 zugeordnete Ende des Saugstutzens 8 in die Saugöffnung 7 eingesteckt werden kann. Dieser Verbindungsbereich ist so gestaltet, dass der Saugstutzen in der Deckelebene beliebig drehbar ist, dass er jedoch in noch näher erläuterter Weise darüber hinaus noch eine weitere zusätzliche Kippbewegung durchführen kann. Wie 35 noch erläutert, ist der Saugstutzen 8 mittels eines nach Art eines Gelenklagers gestalteten Lagers in der Saugöffnung 7 gelagert. In der verbundenen Stellung ist der Saugstutzen 8 innerhalb der Saugöffnung 7 verriegelt. Zum Abnehmen des Saugstutzens 8 kann diese Verriegelung gelöst werden.FIG. 2 shows that the end of the suction nozzle 8 assigned to the housing 2 can be inserted into the suction opening 7. This connection region is designed so that the suction nozzle in the lid plane is arbitrarily rotatable, but that he can still perform in a more detailed manner further explained further additional tilting movement. As 3 5 still explained, the suction nozzle 8 is mounted in the suction opening 7 by means of a bearing designed in the manner of a joint bearing. In the connected position, the suction nozzle 8 locked within the suction port 7. To remove the suction nozzle 8, this lock can be solved.
Die Figur 3 zeigt einen Ausschnitt aus dem Staubraumdeckel 6. Danach ist die Saugöffnung 7 ballig ausgebildet, d.h. der Innendurchmesser nimmt von den beiden Stirnseiten zur Mitte hin kontinuierlich zu. Die Figur 3 zeigt außerdem eine in die Saugöffnung 7 einsetzbare Buchse 14, deren Außenkontur der balligen Kontur der Saugöffnung 7 angepasst ist. Die Bohrung ist zylindrisch ausgebildet, so dass das zugewandte Ende des Saugstutzens 8 schließend darin eingesetzt werden kann. Die Buchse 14 ist außerdem an der dem Saugstutzen 8 zugewandten Seite mit einem Flansch 15 versehen. Die Außenabmessungen der Buchse 14 und die Innenabmessungen der Saugöffnung 7 sind so aufeinander abgestimmt, dass der gebildete Sitz eine Spielpassung ist. Dadurch lässt sich die Buchse 14 leichtgängig innerhalb der Saugöffnung 7 bewegen. Diese Bewegung der Buchse 14 wird durch eine von dem Saugschlauch 9 aufgebrachte Zugkraft bewirkt, wenn sich die den Staubsauger führende Person so weit vom Staubsauger 1 entfernt hat, dass auf den Saugschlauch 9 diese Zugkraft wirkt. Damit die Buchse 14 stets in die Ausgangsstellung zurückfedert, sind an der Außenfläche der Buchse 14 vier jeweils um 90° zueinander versetzte Ausnehmungen 16 vorgesehen, die in Richtung der Drehachse der Buchse 14 verlaufen.3 shows a section of the dust chamber cover 6. Thereafter, the suction port 7 is formed spherical, i. the inner diameter increases continuously from the two end faces towards the middle. FIG. 3 also shows a bush 14 which can be inserted into the suction opening 7 and whose outer contour is adapted to the convex contour of the suction opening 7. The bore is cylindrical, so that the facing end of the suction nozzle 8 can be used closing it. The sleeve 14 is also provided on the suction nozzle 8 side facing with a flange 15. The outer dimensions of the bush 14 and the inner dimensions of the suction opening 7 are coordinated so that the formed seat is a clearance fit. As a result, the sleeve 14 can be easily moved within the suction opening 7. This movement of the bushing 14 is effected by a pulling force applied by the suction hose 9 when the person leading the vacuum cleaner has moved so far away from the vacuum cleaner 1 that this pulling force acts on the suction hose 9. Thus, the sleeve 14 always springs back into the starting position, four four mutually offset by 90 ° recesses 16 are provided on the outer surface of the bush 14, which extend in the direction of the axis of rotation of the bush 14.
Die Figuren 4 und 5 zeigen die Anordnung von drei in den Staubraumdeckel 6 fest eingesetzten elektromechanischen Endschaltern 17, 18, 19, die in ihrer Gesamtheit einen Signalgeber bzw. eine Endlagenabfrageeinheit ergeben. Die Stößel dieser Endschalter 17, 18, 19 sind durch die Bezugszeichen 17', 18' und 19' gekennzeichnet. Wie die Figur 4 zeigt, stehen die Stößel 17', 18', 19' mit der unteren Fläche des Flansches 15 in Kontakt. Die Figur 5 zeigt, dass sie außerdem auf einem zur Drehachse des Saugstutzens 8 konzentrischen Kreisbogen angeordnet sind. In der in der Figur 4 dargestellten Stellung, in der von dem Saugschlauch 9 keine Zugkraft auf die Buchse 14 einwirkt, sind die Stößel 17', 18', 19' ausgefahren und es wird kein Steuersignal erzeugt. In der Figur 5 ist angedeutet, dass die Buchse 14 eine Drehbewegung ausführen kann, während in der Figur 4 dargestellt ist, dass sie darüber hinaus auch noch eine Kippbewegung durchführen kann. In Abhängigkeit von der Richtung der Kippbewegung wird mindestens ein Endschalter 17, 18, 19 betätigt. Dieses Signal bzw. diese Signale werden in die Steuereinheit 20 eingespeist und dort in Ein- und Ausschaltsignale für Motoren M1 und M2 umgewandelt, um die Laufrollen 3 des Staubsaugers 1 anzutreiben. Darüber hinaus kann die Steuereinheit 20 erkennen, von welchem Endschalter 17, 18, 19 die Signale übertragen wurden, so dass darüber hinaus auch mindestens ein Richtungssignal erzeugt wird, so dass der Staubsauger 1 einen Bogen bzw. eine Kurve fährt.Figures 4 and 5 show the arrangement of three fixed in the dust chamber cover 6 electromechanical limit switches 17, 18, 19, which result in their entirety a signal generator and a Endlagenabfrageeinheit. The plunger of these limit switches 17, 18, 19 are denoted by the reference numerals 17 ' , 18 ' and 19 '. As shown in FIG. 4, the plungers 17 ' , 18 ' , 19 'are in contact with the lower surface of the flange 15. FIG. 5 shows that they are also arranged on a circular arc concentric with the axis of rotation of the suction nozzle 8. In the position shown in Figure 4, in which no pulling force from the suction hose 9 acts on the bushing 14, the plunger 17 ' , 18 ' , 19 'are extended and no control signal is generated. In FIG. 5, it is indicated that the bushing 14 can execute a rotational movement, while FIG. 4 shows that, in addition, it can also perform a tilting movement. Depending on the direction of the tilting movement, at least one limit switch 17, 18, 19 is actuated. This signal or these signals are fed to the control unit 20 and converted there into on and off signals for motors M1 and M2 in order to drive the rollers 3 of the vacuum cleaner 1. In addition, the control unit 20 can recognize from which limit switch 17, 18, 19 the signals have been transmitted, so that moreover at least one direction signal is generated, so that the vacuum cleaner 1 travels an arc or a curve.
Die Figur 7 zeigt ein Blockschaltbild zur Ansteuerung der die Laufrollen 3 antreibenden Motoren M1 und M2. Danach besteht die Sensoreinheit aus dem Saugstutzen 8, dem Saugschlauch 9 und der Buchse 14. Die von den Endschaltern 17, 18, 19 erzeugten Signale werden in die Steuereinheit 20 eingespeist. Die Steuereinheit 20 ist außerdem an die Stromversorgung des Staubsaugers 1 gekoppelt, wie durch die beiden Pole (+) und (-) gekennzeichnet ist. Die staubsaugerseitige Steuerelektronik enthält einen Mikrocontroller 21 , und zwei Leistungsschalter 22, 23, um entsprechende Steuersignale an die Motoren M1 und M2 zu übertragen. Im dargestellten Ausführungsbeispiel werden diese Steuersignale durch Drähte übertragen. Im Gegensatz zu der dargestellten Ausführung wäre auch eine drahtlose Übertragung, beispielsweise durch Funk- oder Infrarotsignale möglich. Wie die Figur 7 zeigt, ist es möglich, beide Motoren M1 , M2 gleichzeitig einzuschalten, es ist jedoch auch möglich, dass nur ein Motor eingeschaltet wird. Darüber hinaus könnten die Betriebsspannungen variiert werden, so dass der Staubsauger 1 längs einer Kurve bzw. längs eines Bogens verfährt.FIG. 7 shows a block diagram for controlling the motors M1 and M2 driving the rollers 3. Thereafter, the sensor unit consists of the suction nozzle 8, the suction hose. 9 and the socket 14. The signals generated by the limit switches 17, 18, 19 are fed to the control unit 20. The control unit 20 is also coupled to the power supply of the vacuum cleaner 1, as indicated by the two poles (+) and (-). The vacuum cleaner side control electronics includes a microcontroller 21, and two power switches 22, 23 to transmit respective control signals to the motors M1 and M2. In the illustrated embodiment, these control signals are transmitted by wires. In contrast to the illustrated embodiment, a wireless transmission, for example by radio or infrared signals would be possible. As FIG. 7 shows, it is possible to switch both motors M1, M2 on simultaneously, but it is also possible for only one motor to be switched on. In addition, the operating voltages could be varied so that the vacuum cleaner 1 moves along a curve or along an arc.
Die Erfindung ist nicht auf das dargestellte Ausführungsbeispiel beschränkt. Wesentlich ist, dass der Saugschlauch 9 in Verbindung mit dem Saugstutzen 8 als mechanischer Signalgeber verwendet wird, der in Verbindung mit den Endlageabfrageeinheiten bzw. den Endschaltern 17, 18, 19 Steuersignale in eine Steuereinheit 20 übermittelt, die dort verarbeitet werden und zur Ansteuerung von die Laufrollen 3 antreibenden Motoren M1 , M2 verarbeitet werden. The invention is not limited to the illustrated embodiment. It is essential that the suction hose 9 is used in conjunction with the suction nozzle 8 as a mechanical signal transmitter, which transmits control signals in conjunction with the Endlageauffrageeinheiten or the limit switches 17, 18, 19 in a control unit 20, which are processed there and for controlling the Casters 3 driving motors M1, M2 are processed.
