  • a hose leading to a cylinder vacuum cleaner,
    • wherein the suction tube is connected to the hose by a tubular handle and the handle is equipped with a functional element with which the drive of the brush roller can be switched on and off independently of the operation of the cylinder vacuum cleaner.

    Eine Vorrichtung des beschriebenen Aufbaus ist aus US 4 654 924 bekannt. Das Griffstück der bekannten Saugvorrichtung ist als Handhabungsgerät mit allen für den Saugbetrieb wesentlichen Bedienungselementen ausgerüstet. Es weist einen Ein/Ausschalter für das Sauggebläse des Bodenstaubsaugers, Taster zur Regulierung der Gebläsedrehzahl, Anzeigen in Form von LED's und Displays sowie außerdem einen Ein/Ausschalter für den elektromotorischen Antrieb der Bürstenwalze auf. Der dem Bürstenwalzenantrieb zugeordnete Ein/Ausschalter ist zusammen mit anderen Schaltern und Anzeigeeinrichtungen auf einem Bedienfeld angeordnet. Durch die Anordnung aller für den Saugbetrieb wesentlichen Bedienungselemente am Griffstück soll die Handhabung der Vorrichtung beim Saugvorgang vereinfacht und der Bedienungskomfort verbessert werden.A device of the construction described is from US 4,654,924. The handle of the known suction device is a handling device with all for suction operation essential controls. It has an on / off switch for the suction fan of the cylinder vacuum cleaner, Button for regulating the fan speed, Displays in the form of LEDs and displays as well as an on / off switch for the electric motor drive the brush roller. The one assigned to the brush roller drive On / off switch is together with other switches and Display devices arranged on a control panel. By the arrangement of all control elements essential for suction operation the handle of the device should handle the device simplified during suction and ease of use be improved.

    Bei einem aus DE-A 26 44 697 bekannten Saugreinigungsgerät ist das zwischen Saugrohr und Saugschlauch angeordnete Griffstück mit einem Sensorschalter ausgerüstet, durch dessen Berührung das Sauggebläse des an den Saugschlauch angeschlossenen Bodenstaubsaugers eingeschaltet wird. Die Schaltungsanordnung kann so eingerichtet sein, dass das Sauggebläse selbsttätig abschaltet, wenn das Griffstück aus der Hand gelegt wird. Mit dem Sauggebläse werden etwaige, an den Stromkreis des Sauggebläses angeschlossene elektrische Zusatzgeräte mit abgeschaltet.In a suction cleaning device known from DE-A 26 44 697 is that arranged between the suction pipe and suction hose Handle piece equipped with a sensor switch, by whose touch the suction fan to the suction hose connected vacuum cleaner is switched on. The Circuit arrangement can be set up so that the Suction blower switches off automatically when the handle is off is laid. With the suction fan, any electrical connected to the circuit of the suction fan Additional devices with switched off.

    Bei der eingangs beschriebenen Vorrichtung kann die elektromotorisch angetriebene Bürstenwalze einen textilen Bodenbelag schädigen, wenn z.B. bei kurzzeitigen Unterbrechungen des Saugvorganges die Bodendüse mit rotierender Bürstenwalze abgestellt wird. Um eine Schädigung empfindlicher Böden durch Fehlbedienungen zu vermeiden, ist es bekannt, die Bodendüse mit einem Bewegungssensor auszurüsten, der bei einem detektierten Stillstand der Düse den Antrieb der Bürstenwalze abschaltet (US 2 323 554, DE-A 43 43 432).In the device described above, the electric motor-driven brush roller a textile Damage the flooring, e.g. if for short interruptions of the suction process the floor nozzle with rotating Brush roller is turned off. To make damage more sensitive It is to prevent floors from being operated incorrectly known to equip the floor nozzle with a motion sensor, which is detected when the nozzle is at a standstill The brush roller drive switches off (US Pat. No. 2,323,554, DE-A 43 43 432).

    Die Schaltung des elektromotorischen Antriebs durch einen Bewegungssensor hat jedoch den gravierenden Nachteil, dass die Bürstenwalze sich durch eine unbeabsichtigte Bewegung der Bodendüse plötzlich in Bewegung setzen kann, ohne dass dies von dem Benutzer erwartet wird. Dadurch resultiert ein beachtliches Verletzungsrisiko. Um das Verletzungsrisiko zu mindern, ist ein zusätzlicher Sicherheitsschalter erforderlich, der den Antrieb der Bürstenwalze abschaltet, sobald die Bodendüse vom Boden abgehoben wird. Als Sicherheitsschalter eignet sich beispielsweise ein bodenseitiges Tastelement, das durch eine vertikale Stellbewegung den Elektromotor der Bürstenwalze schaltet (JP-A 4 327 821). Als Sicherheitsschalter ist auch ein Unterdrucksensor einsetzbar, der nach Maßgabe des gemessenen Unterdrucks den Antrieb der Bürstenwalze ein- und ausschaltet. Bei großem Unterdruck, der für den Betrieb auf einem Teppichboden charakteristisch ist, wird der Antrieb eingeschaltet. Wird die Bodendüse vom Boden abgehoben oder auf einem glatten Untergrund eingesetzt, erfolgt eine Abschaltung der Bürstenwalze.The circuit of the electric motor drive by a However, motion sensor has the serious disadvantage that the brush roller is moving inadvertently the floor nozzle can suddenly start moving without it this is expected from the user. This results in a considerable risk of injury. To reduce the risk of injury an additional safety switch is required, which switches off the brush roller drive as soon as the floor nozzle is lifted off the floor. As a safety switch a touch element on the bottom is suitable, for example, the electric motor by means of a vertical adjustment movement the brush roller switches (JP-A 4 327 821). As Safety switch, a vacuum sensor can also be used, which according to the measured vacuum The brush roller drive switches on and off. With big Negative pressure necessary for operation on a carpeted floor is characteristic, the drive is switched on. Becomes the floor nozzle lifted off the floor or on a smooth Used underground, the Brush roller.

    Zusatzeinrichtungen an einer Bodendüse, die einerseits aus einem Bewegungssensor und andererseits aus einem separaten Sicherheitsschalter zur Minderung des Verletzungsrisikos bestehen, sind aufwendig. Oft steht auch der Einbauraum für die Unterbringung eines Bewegungssensors und eines zusätzlichen Sicherheitsschalters nicht zur Verfügung. In DE-A 43 43 432 (Fig. 3 und 4) wird vorgeschlagen, die Bodendüse mit einem elektromechanischen Schalter auszurüsten, der sowohl die Funktion eines Bewegungssensors als auch eines Lagesensors erfüllt. Der Lagesensor spricht als Sicherheitsschalter an, wenn die Bodendüse über Kopf gedreht wird. Es bleibt ein erhebliches Verletzungsrisiko, da die Bürstenwalze sich unvermittelt in Bewegung setzen kann, wenn die Bodendüse vom Boden zwar abgehoben, aber nicht über Kopf gedreht wird. Additional equipment on a floor nozzle, on the one hand a motion sensor and on the other hand from a separate one Safety switch to reduce the risk of injury exist are expensive. Often the installation space also stands for the placement of a motion sensor and an additional one Safety switch not available. In DE-A 43 43 432 (Fig. 3 and 4) is proposed with the floor nozzle to equip an electromechanical switch that both the function of a motion sensor as well as a position sensor Fulfills. The position sensor speaks as a safety switch when the floor nozzle is turned upside down. It remains a significant risk of injury since the brush roller can start moving suddenly when the Floor nozzle lifted off the floor, but not overhead is rotated.

    Der Erfindung liegt die Aufgabe zugrunde, die eingangs beschriebene Vorrichtung so weiter auszubilden, dass eine automatische Abschaltung des Bürstenwalzenantriebs gewährleistet ist, sobald der Saugvorgang unterbrochen wird, und dass außerdem die Gefahr einer Verletzung durch die rotierende Bürstenwalze weitgehend eliminiert ist.The invention is based on the object further described device so that a automatic switch-off of the brush roller drive guaranteed is as soon as the suction process is interrupted, and that also the risk of injury from the rotating Brush roller is largely eliminated.

    Die Aufgabe wird erfindungsgemäß durch den Gegenstand der Ansprüche 1 und 8 gelöst. Sobald der Benutzer den Saugvorgang unterbricht und das zumindest mit einer Hand geführte Griffstück loslässt, erfolgt unmittelbar oder mit einer geringen Zeitverzögerung eine Abschaltung des Bürstenwalzenantriebs. Das Sauggebläse des Bodenstaubsaugers kann unverändert weiterlaufen und ist durch einen separaten Ein/Ausschalter schaltbar. Ein Verletzungsrisiko durch die rotierende Bürstenwalze ist weitgehend eliminiert, da durch das Saugrohr, das beispielsweise als Teleskoprohr eine Länge von 500 mm bis 1100 mm aufweist, ein großer Abstand zwischen dem Funktionselement und der Bürstenwalze gewahrt ist. Eine Fehlbedienung dergestalt, dass mit einer Hand das fernliegende Funktionselement betätigt und mit der anderen Hand die Bodendüse nahe der Bürstenwalze erfasst wird, ist ausgeschlossen. Die erfindungsgemäße Lehre erlaubt auf überraschend einfache Weise eine funktionssichere Abschaltung der rotierenden Bürstenwalze, wenn die Bodendüse abgestellt wird, und zugleich schützt sie den Benutzer wirksam vor einer Verletzung durch die rotierende Bürstenwalze. Die erfindungsgemäße Lehre zeichnet sich durch den weiteren Vorteil aus, dass sie keinen zusätzlichen Einbauraum in der Bodendüse beansprucht.The object is achieved by the subject matter of claims 1 and 8. As soon as the user stops the suction process, at least lets go with a hand-held grip immediately or with a slight time delay a shutdown of the brush roller drive. The suction fan the cylinder vacuum cleaner can and will continue to run unchanged can be switched by a separate on / off switch. A risk of injury through the rotating brush roller is largely eliminated because of the intake manifold, for example as telescopic tube a length of 500 mm to 1100 mm has a large distance between the functional element and the brush roller is preserved. Mishandling in such a way that the remote functional element with one hand actuated and with the other hand the floor nozzle is detected near the brush roller is excluded. The Teaching according to the invention allows for surprisingly simple Way a reliable shutdown of the rotating Brush roller when the floor nozzle is turned off, and at the same time it effectively protects the user from injury through the rotating brush roller. The invention Teaching is characterized by the further advantage that they have no additional installation space in the floor nozzle claimed.

    Im Hinblick auf die konstruktive Ausführung der erfindungsgemäßen Lehre bieten sich verschiedene Möglichkeiten an. Das Funktionselement kann aus einem federbelasteten Bedienhebel sowie einem von dem Bedienhebel betätigbaren Taster, der z.B. als Mikroschalter ausgeführt ist, bestehen. Als Funktionselement eignen sich ferner Sensoren, die bei einer Berührung des Griffstückes ansprechen. In Betracht kommen beispielsweise Wärmesensoren, kapazitive Sensoren, Lichtsensoren und dergleichen.With regard to the structural design of the invention Teaching offers various options on. The functional element can consist of a spring-loaded Operating lever and one that can be actuated by the operating lever Button which e.g. is designed as a microswitch. Sensors are also suitable as functional elements, that respond when the handle is touched. In For example, capacitive heat sensors are considered Sensors, light sensors and the like.

    Die Umsetzung des Erkennungssignals in einen Schaltvorgang ist ebenfalls auf verschiedene Weise technisch realisierbar. Die einfachste Lösung besteht darin, dass das Funktionselement in eine von dem Bodenstaubsauger zum Bürstenwalzenantrieb geführte Energieversorgungsleitung eingebunden ist. Das Funktionselement ist zweckmäßig als Taster ausgeführt, der unmittelbar oder mittelbar über einen Bedienhebel bei Erfassen des Griffstückes betätigbar ist und den Stromkreis zum Antrieb der Bürstenwalze schließt sowie den Stromkreis unterbricht, sobald das Griffstück losgelassen wird.The conversion of the detection signal into a switching process is also technically feasible in various ways. The simplest solution is that the functional element into one of the cylinder vacuum cleaners for the brush roller drive guided power supply line integrated is. The functional element is useful as a button executed directly or indirectly via a Control lever can be actuated when gripping the handle and closes the circuit for driving the brush roller as well as interrupting the circuit as soon as the handle is released.

    Eine andere Ausführung der Erfindung sieht vor, dass die Bodendüse eine elektronische Schaltungsanordnung enthält, die Signale des Funktionselementes verarbeitet und den Antrieb der Bürstenwalze schaltet. Die Signalübertragung kann leitungsgebunden über ein Kabel erfolgen. Bevorzugt ist eine Ausführung, bei der die Bodendüse sowie das Funktionselement Einrichtungen für eine drahtlose Signalübertragung, z.B. durch Infrarot, Ultraschall oder Funk, aufweisen. Die Energie für die Sensorik und Signalübertragung kann durch eine im Griffstück angeordnete Batterie bereitgestellt werden. Ferner besteht die Möglichkeit, in dem rohrförmigen Kanal des Griffstückes eine vom Luftstrom angetriebene Turbine anzuordnen, die einen Generator zur Stromversorgung des Funktionselementes treibt. Schließlich besteht die Möglichkeit, das Griffstück außerhalb des Handgriffbereiches mit Solarzellen für die Stromversorgung des Funktionselementes zu bestücken.Another embodiment of the invention provides that the Floor nozzle contains an electronic circuit arrangement, processed the signals of the functional element and the Brush roller drive switches. The signal transmission can be wired via a cable. Prefers is a version in which the floor nozzle and the functional element Devices for wireless signal transmission, e.g. by infrared, ultrasound or radio. The energy for sensors and signal transmission can be provided by a battery arranged in the handle become. There is also the possibility of tubular duct of the handle one of the air flow to arrange a driven turbine that a generator for Power supply of the functional element drives. Finally there is the possibility of the handle outside the Handle area with solar cells for the power supply of the functional element.

    Die Verarbeitung des Erkennungssignals erfolgt durch eine Elektronik in der Bodendüse. Die dafür vorgesehen Schaltungsanordnung kann ein Zeitglied enthalten und so ausgebildet sein, dass die Abschaltung des Bürstenwalzenantriebs bei ausbleibendem Signal mit einer vorgegebenen zeitlichen Verzögerung erfolgt.The detection signal is processed by a Electronics in the floor nozzle. The circuit arrangement provided for this can contain a timer and so designed be that the shutdown of the brush roller drive if there is no signal with a specified one time delay occurs.

    Das Funktionselement ist bei entsprechender Formgestaltung des Griffstückes in das Griffstück integrierbar. Das Funktionselement kann aber auch als separates, nachträglich am Griffstück befestigbares Bauteil ausgeführt werden. Bei dieser Ausführung weist das Funktionselement ein am Griffstück befestigbares Gehäuse auf, an dem vorzugsweise ein federbelasteter Bedienhebel gehalten ist. Das Gehäuse kann ein Batteriefach sowie Einrichtungen für die Signalerkennung und Signalübertragung enthalten. In weiterer Ausgestaltung lehrt die Erfindung, dass das Funktionselement durch einen separaten Schalter ausschaltbar ist. Bei ausgeschaltetem Funktionselement ist der Antrieb der Bürstenwalze abgeschaltet und kann nicht in Betrieb gesetzt werden. Damit hat der Benutzer die Möglichkeit, die Bodendüse ohne rotierende Düsenwalze zu verwenden. Das ist vorteilhaft beim Saugen von empfindlichen Bodenbelägen, sehr hochflorigen Teppichen und Glattböden. Besteht das Funktionselement aus einem von einem Bedienhebel betätigbaren Taster, so bietet sich auch die Möglichkeit an, eine Einrichtung vorzusehen, mit der der Bedienhebel des Funktionselementes in der Funktionsstellung, bei der der Antrieb der Bürstenwalze abgeschaltet ist, mechanisch blockierbar ist.The functional element is with an appropriate design the handle can be integrated into the handle. The functional element can also be used as a separate, later on Handle piece attachable component are executed. at In this version, the functional element has a handle attachable housing, on which preferably a spring-loaded control lever is held. The housing can a battery compartment and facilities for signal detection and signal transmission included. In a further embodiment, the invention teaches that Functional element can be switched off by a separate switch is. When the functional element is switched off, the The brush roller drive is switched off and cannot move in Operation. This enables the user to to use the floor nozzle without a rotating nozzle roller. This is advantageous when vacuuming sensitive ones Floor coverings, very deep-pile carpets and smooth floors. The functional element consists of one of an operating lever actuable button, so there is also the possibility to provide a facility with which the Operating lever of the functional element in the functional position, where the drive of the brush roller is switched off is mechanically lockable.
