Description
Die Erfindung betrifft eine Vorrichtung zum Saugen mit
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.An apparatus of the described construction is made US 4,654,924. The handle of the known suction device is as a handling device with all for the suction operation equipped with essential controls. It has an on / off switch for the suction fan of the cylinder vacuum cleaner, Button for adjusting 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 roll on. Of the brush roller drive associated On / off switch is along with other switches and Display devices arranged on a control panel. By the arrangement of all essential for the suction controls on the handle should handle the device simplified during the suction process and the 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 one known from DE-A 26 44 697 Saugreinigungsgerät this is arranged between intake manifold and suction hose Handle equipped with a sensor switch, through whose touch the suction fan of the suction hose connected vacuum cleaner is turned on. The Circuitry may be arranged such that the Suction fan automatically turns off when the handle off the hand is laid. With the suction fan, any, connected to the circuit of the suction fan electrical Accessories 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 flooring if e.g. for short-term interruptions the suction of the floor nozzle with rotating Brush roller is turned off. To be more sensitive to injury Avoiding floors due to incorrect operation is what it is known to equip the floor nozzle with a motion sensor, at a detected stoppage of the nozzle the Drive of the brush roller turns off (US 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 Motion sensor, however, has the serious disadvantage that the brush roll itself by an unintentional movement The floor nozzle can suddenly start moving without it this is expected by the user. This results in a considerable risk of injury. To the injury risk too reduce, an additional safety switch is required, which shuts off the drive of the brush roller as soon as possible the floor nozzle is lifted off the ground. As a safety switch is suitable, for example, a bottom-side probe element, that by a vertical adjusting movement the electric motor the brush roller switches (JP-A 4 327 821). When Safety switch is also a vacuum sensor can be used, in accordance with the measured negative pressure the Drive the brush roller on and off. At large Negative pressure for operation on a carpet floor is characteristic, the drive is turned on. Becomes the floor nozzle lifted off the ground or on a smooth Underground used, there is a shutdown of 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 Safety switch to reduce the risk of injury exist, are expensive. Often, the installation space for the accommodation of a motion sensor and an additional Safety switch not available. In DE-A 43 43 432 (Fig. 3 and 4) is proposed, the floor nozzle with to equip an electromechanical switch, 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 move abruptly when the Floor nozzle lifted from the ground, but not over head is turned.
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, the beginning described device so on, that a automatic shutdown of the brush roller drive ensures is, as soon as the suction process is interrupted, and in addition, the risk of injury from the rotating Brush roller is largely eliminated.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Funktionselement bei Erfassen des Griffstückes den Antrieb der Bürstenwalze einschaltet und den Bürstenwalzenantrieb wieder ausschaltet, sobald das Griffstück losgelassen wird. 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 in that the Functional element upon detection of the handle the drive the brush roller turns on and the brush roller drive switches off again as soon as the handle is released. Once the user interrupts the suction and that at least With a hand-held grip lets go, takes place directly or with a small time delay a shutdown of the brush roller drive. The suction fan the vacuum cleaner can continue to run and is unchanged switchable by a separate on / off switch. A risk of injury through the rotating brush roller is largely eliminated, as by the suction tube, for example as a telescopic tube a length of 500 mm to 1100 mm has, a large distance between the functional element and the brush roller is maintained. An operating error of this kind, that with one hand the remote functional element pressed 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 functionally safe 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 inventive 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 possibilities on. The functional element can be made of a spring-loaded Operating lever and an operable by the operating lever Button, e.g. designed as a microswitch exist. Further suitable as functional elements are sensors, which respond to a touch of the handle. In Consider, for example, thermal sensors, capacitive 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 implementation of the detection signal in a switching operation is also technically feasible in various ways. The simplest solution is that the functional element in one of the vacuum cleaner to the brush roller drive integrated power supply line is. The functional element is useful as a button executed, directly or indirectly via a Operating lever is operable upon detection of the handle and closes the circuit for driving the brush roller as well as the circuit breaks 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, processes the signals of the functional element and the Drive of the brush roller switches. The signal transmission Can be wired via a cable. Prefers is an embodiment in which the floor nozzle and the functional element Facilities for wireless signal transmission, e.g. by infrared, ultrasound or radio. The energy for the sensors and signal transmission can be provided by a battery arranged in the handle become. There is also the possibility in the tubular channel of the handle one from the air flow to arrange driven turbine, which is a generator for Power supply of the functional element drives. After all there is the possibility of the handle outside the Handle area with solar cells for the power supply to equip 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 processing of the detection signal is performed by a Electronics in the floor nozzle. The circuit provided for this purpose can contain a timer and trained be that shutdown of the brush roller drive in the absence of a signal with a predetermined time delay takes place.
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.
