Such a suction can lead to impairment of the function or damage to the suction drive 9.
- the filling level H with a corresponding inclination of the hand-guiding part 2 2 reaches the area of the air intake opening 23 from the vertical in the direction of the bottom surface B. This is all the more so since the joint arrangement 4 enables the hand guide part 2 to be inclined on all sides by up to 75 ° from the vertical. In such a case, an inclination-induced suction of liquid through the air suction opening 23 cannot easily be avoided.
- a detection device 25 is provided in the present case, which is set up to detect an angle of inclination N of the manual guide part 2, the control device 20 being set up in such a way that, depending on the angle of inclination N detected, a protective function for preventing inclination-induced suction of liquid from the receptacle 7 is controllable through the air intake opening 23.

- a computing unit 31 of the control device 20 compensates for this fundamentally known manner from the detected inclination angle N with the stored inclination angles N1, N2, the corresponding control signal S1 or S2 being transmitted as soon as the detected inclination angle N corresponds to the correspondingly stored inclination angle N1 or N2.
- the first inclination angle N1 is smaller in magnitude than the second inclination angle N2. This leads to the fact that, in order to protect the suction turbine 9 against inadvertent suction of liquid, the suction turbine 9 itself is first switched off as soon as the first inclination angle N1 is reached.
- the tool drive 12 is additionally switched off. As a result, operational safety of the wet cleaning device 1 can be improved even further.
- the drives 9, 12 can also be switched off in a staggered order.

Eine derartige Nassreinigungsvorrichtung ist in Form einer Scheuer-Saug-Maschine aus der
Aufgabe der Erfindung ist es, eine Nassreinigungsvorrichtung der eingangs genannten Art zu schaffen, die eine verbesserte Betriebssicherheit ermöglicht.The object of the invention is to provide a wet cleaning device of the type mentioned at the outset which enables improved operational reliability.
Diese Aufgabe wird dadurch gelöst, dass eine mit der Steuereinrichtung verbundene Erfassungseinrichtung vorgesehen ist, die zur Erfassung eines Neigungswinkels des Handführungsteils eingerichtet ist, wobei die Steuereinrichtung derart eingerichtet ist, dass in Abhängigkeit des erfassten Neigungswinkels eine Schutzfunktion zur Vermeidung eines neigungsbedingten Ansaugens von Flüssigkeit aus dem Aufnahmebehälter durch die Luftansaugöffnung steuerbar ist. Durch die erfindungsgemäße Lösung wird vermieden, dass im Aufnahmebehälter befindliche Flüssigkeit neigungsbedingt vom Saugantrieb angesaugt und dieser hierdurch in seiner Funktion beeinträchtigt oder beschädigt wird. Ein solches Ansaugen ist grundsätzlich dann möglich, wenn das Handführungsteil und damit der Aufnahmebehälter im Betriebszustand ausgehend von der Senkrechten derart in Richtung der Bodenfläche geneigt wird, dass ein Flüssigkeitspegel im Aufnahmebehälter in den Bereich der Luftansaugöffnung gelangt oder Flüssigkeit in die Luftansaugöffnung hineinschwappt. Die erfindungsgemäße Lösung vermeidet dies, indem der Neigungswinkel des Handführungsteils erfasst und in Abhängigkeit des erfassten Neigungswinkels die besagte Schutzfunktion steuerbar ist. Die Schutzfunktion kann insbesondere eine Abschaltung des Saugantriebs umfassen. Alternativ oder zusätzlich kann die Schutzfunktion eine Abschaltung des Werkzeugantriebs umfassen. Weiter alternativ oder zusätzlich kann die Schutzfunktion eine Aktivierung einer Warneinrichtung zur Abgabe eines Warnsignals umfassen. Die Steuereinrichtung kann insbesondere in Form eines elektrischen und/oder elektronischen Steuergeräts realisiert sein. Die Steuereinrichtung ist vorzugsweise im Bereich des Handführungsteils angeordnet. Der Steuereinrichtung kann eine manuell betätigbare Bedieneinheit zugeordnet sein, mittels derer der Saugantrieb und/oder der Werkzeugantrieb manuell an- und/oder abschaltbar sein können. Alternativ oder zusätzlich kann der Steuereinrichtung zu diesem Zweck eine per Fuß und/oder manuell betätigbare Bedieneinheit zugeordnet sein, die insbesondere am Bodenteil angeordnet sein kann. Die Erfassungseinrichtung kann drahtgebunden und/oder drahtlos mit der Steuereinrichtung wirkverbunden sein. Die Erfassungseinrichtung kann zur Erfassung eines Neigungswinkels des Handführungsteils relativ zu dem Bodenteil und/oder relativ zu der Bodenfläche und insoweit zur Erfassung eines relativen Neigungswinkels eingerichtet sein. Alternativ oder zusätzlich kann die Erfassungseinrichtung zur Erfassung eines Neigungswinkels in Bezug auf das Erdschwerefeld und insoweit - vereinfacht ausgedrückt - zur Erfassung eines absoluten Neigungswinkels eingerichtet sein. Vorzugsweise weist die Erfassungseinrichtung wenigstens einen Sensor auf, der zur Erfassung des Neigungswinkels eingerichtet ist. Das Bodenbearbeitungswerkzeug weist vorzugsweise zwei Tellerwerkzeuge auf, die um jeweils eine im Wesentlichen vertikal orientierte Drehachse zueinander gegenläufig rotierbar sind. Vorzugsweise ist das Bodenbearbeitungswerkzeug derart gestaltet, dass es im Betriebszustand einen permanenten linearen Vortrieb auf das Bodenteil bewirkt. Sofern das Bodenbearbeitungswerkzeug zwei Tellerwerkzeuge aufweist, können zu diesem Zweck die Drehachsen der Tellerwerkzeuge ausgehend von der Senkrechten geringfügig gegeneinander geneigt sein, so dass aufgrund einer in Umfangsrichtung der Tellerwerkzeuge ungleichförmigen Reibkraftverteilung der Vortrieb des Bodenteils bewirkt ist. Das Bodenbearbeitungswerkzeug ist vorzugsweise derart gestaltet, dass der generierte Vortrieb die Nassreinigungsvorrichtung selbstfahrend - ohne ein Schieben oder ein Ziehen einer Bedienperson am Handführungsteil - auf der Bodenfläche bewegt, wobei das Handführungsteil lediglich einer manuellen Richtungssteuerung der Bewegung dient. Die Gelenkanordnung weist zwei Gelenkachsen auf und ermöglicht insoweit eine doppelgelenkige Verschwenkbarkeit des Handführungsteils relativ zu dem Bodenführungsteil. Vorzugsweise sind die Gelenkachsen orthogonal zueinander orientiert. Hierdurch ist das Handführungsteil ausgehend von einer senkrechten Orientierung nicht etwa lediglich in einer Schwenkebene, sondern allseitig räumlich verschwenkbar. Die Gelenkanordnung ist vorzugsweise derart gestaltet, dass das Handführungsteil ausgehend von der Senkrechten um wenigstens 30°, bevorzugt um 45° bis 60° und besonders bevorzugt um 60° bis 75° allseitig neigbar ist, ohne dass das Bodenteil hierbei von der Bodenfläche abgehoben oder gekippt wird. Insbesondere aufgrund dieser allseitigen Verschwenkbarkeit kann der Flüssigkeitspegel selbst bei einem bestimmungsgemäßen Gebrauch der Nassreinigungsvorrichtung ohne weiteres in den Bereich der Luftansaugöffnung gelangen.This object is achieved in that a detection device is provided which is connected to the control device and is set up to detect an angle of inclination of the manual guide part, the control device being set up in such a way that, depending on the detected angle of inclination, a protective function for avoiding suction-induced liquid suction from the Receptacle is controllable through the air intake opening. The solution according to the invention prevents the liquid in the receptacle from being sucked in by the suction drive as a result of the inclination and the function of the suction drive being impaired or damaged as a result. Such a suction is fundamentally possible when the manual guide part and thus the receptacle is inclined in the operating state, starting from the vertical, in the direction of the bottom surface in such a way that a liquid level in the receptacle reaches the area of the air suction opening or liquid spills into the air suction opening. The solution according to the invention avoids this by detecting the angle of inclination of the manual guide part and the protective function can be controlled as a function of the detected angle of inclination. The protective function can in particular include switching off the suction drive. Alternatively or additionally, the protective function can include switching off the tool drive. Further alternatively or additionally, the protective function can include activation of a warning device for emitting a warning signal. The control device can in particular in the form of an electrical and / or electronic control unit. The control device is preferably arranged in the region of the manual guide part. The control device can be assigned a manually operable operating unit, by means of which the suction drive and / or the tool drive can be switched on and / or off manually. As an alternative or in addition, the control device can be assigned a control unit which can be actuated by foot and / or manually and which can in particular be arranged on the base part. The detection device can be wired and / or wirelessly operatively connected to the control device. The detection device can be set up to detect an angle of inclination of the manual guide part relative to the bottom part and / or relative to the bottom surface and to this extent to detect a relative angle of inclination. Alternatively or additionally, the detection device can be set up to detect an angle of inclination with respect to the earth's gravitational field and, to put it simply, to detect an absolute angle of inclination. The detection device preferably has at least one sensor which is set up to detect the angle of inclination. The tillage tool preferably has two plate tools, each of which can be rotated in opposite directions about an essentially vertically oriented axis of rotation. The tillage tool is preferably designed in such a way that, in the operating state, it brings about permanent linear propulsion on the bottom part. If the tillage tool has two plate tools, the axes of rotation of the plate tools can be slightly inclined towards each other starting from the vertical, so that the ground part is propelled due to a non-uniform distribution of the friction force in the circumferential direction of the plate tools. The soil cultivation tool is preferably designed in such a way that the generated propulsion moves the wet cleaning device on the floor surface in a self-driving manner - without pushing or pulling an operator on the hand guide part, the hand guide part only serving to manually control the direction of the movement. The articulation arrangement has two articulation axes and, in this respect, enables the hand guide part to be pivoted in a double articulation relative to the floor guide part. The joint axes are preferably oriented orthogonally to one another. As a result, starting from a vertical orientation, the manual guide part cannot be pivoted spatially on all sides, but only in one pivot plane. The joint arrangement is preferably designed such that the hand guide part can be inclined on all sides, starting from the vertical, by at least 30 °, preferably 45 ° to 60 ° and particularly preferably 60 ° to 75 °, without the floor part being lifted or tilted from the floor surface becomes. In particular, due to this pivotability on all sides, the liquid level can easily reach the area of the air intake opening even when the wet cleaning device is used as intended.
Die erfindungsgemäße Lösung eignet sich in besonders vorteilhafter Weise zur Nassreinigung von Fußböden in einem Gebäudeinnenbereich. Dessen ungeachtet kann die erfindungsgemäße Lösung auch zur Nassreinigung von Fußböden in einem Gebäudeaußenbereich eingesetzt werden.The solution according to the invention is particularly advantageously suitable for wet cleaning of floors in an interior of a building. Regardless of this, the solution according to the invention can also be used for wet cleaning of floors in an outside area of a building.
In Ausgestaltung der Erfindung ist die Steuereinrichtung zur Steuerung der Schutzfunktion derart eingerichtet, dass in Abhängigkeit des erfassten Neigungswinkels der Saugantrieb und/oder der Werkzeugantrieb abschaltbar ist. Die Schutzfunktion umfasst demnach eine neigungsabhängige automatische Abschaltung des Saugantriebs und/oder des Werkzeugantriebs. Zu diesem Zweck ist die Steuereinrichtung wenigstens mittelbar mit dem Saugantrieb und/oder dem Werkzeugantrieb wirkverbunden. Die Wirkverbindung kann drahtgebunden und/oder drahtlos ausgebildet sein. Dabei kann die Steuereinrichtung mit dem Saugantrieb und/oder dem Werkzeugantrieb selbst und/oder mit einer dem jeweiligen Antrieb zugeordneten Energieversorgungseinrichtung wirkverbunden sein. Sofern die Steuereinrichtung derart eingerichtet ist, dass sowohl der Saugantrieb als auch der Werkzeugantrieb automatisch neigungsabhängig abschaltbar sind, können die jeweiligen Abschaltungen gleichzeitig - bei ein- und demselben Neigungswinkel des Handführungsteils - oder gestaffelt - bei unterschiedlichen Neigungswinkeln des Handführungsteils - steuerbar sein. Bei dieser Ausgestaltung der Erfindung ist es zudem vorteilhaft, wenn die Steuereinrichtung derart eingerichtet ist, dass in Abhängigkeit des erfassten Neigungswinkels der Saugantrieb und/oder der Werkzeugantrieb - nach einer zuvor erfolgten automatischen neigungsabhängigen Abschaltung - einschaltbar ist.In an embodiment of the invention, the control device for controlling the protective function is set up in such a way that the suction drive and / or the tool drive can be switched off as a function of the detected angle of inclination. The protective function accordingly includes an inclination-dependent automatic shutdown of the suction drive and / or the tool drive. For this purpose, the control device is at least indirectly operatively connected to the suction drive and / or the tool drive. The active connection can be wired and / or wireless. The control device can be operatively connected to the suction drive and / or the tool drive itself and / or to an energy supply device assigned to the respective drive. If the control device is set up in such a way that both the suction drive and the tool drive can be switched off automatically depending on the inclination, the respective switch-offs can be controlled simultaneously - at one and the same angle of inclination of the hand guide part - or staggered - at different angles of inclination of the hand guide part. In this embodiment of the invention, it is also advantageous if the control device is set up in such a way that, depending on the detected angle of inclination, the suction drive and / or the tool drive can be switched on - after a previous automatic inclination-dependent shutdown.
In weiterer Ausgestaltung der Erfindung übermittelt die Steuereinrichtung in Abhängigkeit des erfassten Neigungswinkels ein erstes Steuersignal an den Saugantrieb zur Abschaltung desselben und/oder die Steuereinrichtung übermittelt in Abhängigkeit des erfassten Neigungswinkels ein zweites Steuersignal an den Werkzeugantrieb zur Abschaltung desselben. Das erste Steuersignal und/oder das zweite Steuersignal können jeweils binär oder analog sein. Die Übermittlung des ersten Steuersignals und/oder des zweiten Steuersignals kann drahtlos oder drahtgebunden erfolgen.In a further embodiment of the invention, the control device transmits a first control signal to the suction drive to switch it off, depending on the detected angle of inclination, and / or the control device transmits a second control signal to the tool drive to switch it off, depending on the detected angle of inclination. The first control signal and / or the second control signal can each be binary or analog. The first control signal and / or the second control signal can be transmitted wirelessly or by wire.
In weiterer Ausgestaltung der Erfindung übermittelt die Steuereinrichtung das erste Steuersignal bei Erreichen eines ersten Neigungswinkels und/oder die Steuereinrichtung übermittelt das zweite Steuersignal bei Erreichen eines zweiten Neigungswinkels. Der erste Neigungswinkel kann gleich dem zweiten Neigungswinkel sein. Alternativ kann der erste Neigungswinkel kleiner oder größer als der zweite Neigungswinkel sein oder umgekehrt. Sofern eine automatische neigungswinkelabhängige Abschaltung sowohl des Saugantriebs als auch des Werkzeugantriebs vorgesehen ist, kann bei letztgenannter Variante eine gestaffelte Abschaltung erreicht werden. Beispielsweise kann bei Erreichen des ersten Neigungswinkels zunächst der Saugantrieb abgeschaltet werden. Wird das Handführungsteil hiernach dennoch weiter verschwenkt und der zweite Neigungswinkel, der größer ist als der erste Neigungswinkel, erreicht, wird zusätzlich der Werkzeugantrieb abgeschaltet. Alternativ kann eine Abschaltung der Antriebe in hierzu umgekehrter Reihenfolge vorgesehen sein. Durch diese Ausgestaltung der Erfindung ergeben sich weitere Vorteile im Hinblick auf die Betriebssicherheit der Nassreinigungsvorrichtung.In a further embodiment of the invention, the control device transmits the first control signal when a first inclination angle is reached and / or the control device transmits the second control signal when a second inclination angle is reached. The first angle of inclination can be equal to the second angle of inclination. Alternatively, the first angle of inclination can be smaller or larger than the second angle of inclination or vice versa. If an automatic switch-off of both the suction drive and the tool drive, which is dependent on the inclination angle, is provided, a staggered one can be used in the latter variant Shutdown can be achieved. For example, when the first angle of inclination is reached, the suction drive can first be switched off. If the manual guide part is nevertheless pivoted further afterwards and the second inclination angle, which is greater than the first inclination angle, is reached, the tool drive is additionally switched off. Alternatively, the drives can be switched off in the reverse order to this. This configuration of the invention results in further advantages with regard to the operational safety of the wet cleaning device.
In weiterer Ausgestaltung der Erfindung ist eine mit der Steuereinrichtung verbundene Warneinrichtung vorgesehen, wobei die Steuereinrichtung zur Steuerung der Schutzfunktion derart eingerichtet ist, dass in Abhängigkeit des erfassten Neigungswinkels die Warneinrichtung zur Abgabe eines Warnsignals aktivierbar ist. Bei dieser Ausgestaltung der Erfindung umfasst die Schutzfunktion demnach die Abgabe eines Warnsignals. Zu diesem Zweck ist die Warneinrichtung vorgesehen und mit der Steuereinrichtung verbunden. Die Warneinrichtung kann eine akustische, optische und/oder mechanische Warneinrichtung sein. Demnach kann das Warnsignal insbesondere in Form eines Tons, eines Lichtsignals und/oder einer mechanischen Vibration oder dergleichen abgegeben werden. Sofern die Schutzfunktion zusätzlich eine neigungsabhängige automatische Abschaltung des Saugantriebs und/oder des Werkzeugantriebs umfasst, ist es besonders vorteilhaft, wenn die Warneinrichtung vorgelagert zu einer Abschaltung - bei einem vergleichsweise geringeren Neigungswinkel des Handführungsteils - aktiviert wird. Auf diese Weise kann eine abschaltbedingte Unterbrechung des Betriebszustands vermieden und ein effizienter Betrieb der Nassreinigungsvorrichtung ermöglicht werden.In a further embodiment of the invention, a warning device connected to the control device is provided, the control device being set up to control the protective function in such a way that the warning device for emitting a warning signal can be activated as a function of the detected angle of inclination. In this embodiment of the invention, the protective function accordingly comprises the emission of a warning signal. For this purpose, the warning device is provided and connected to the control device. The warning device can be an acoustic, optical and / or mechanical warning device. Accordingly, the warning signal can be emitted in particular in the form of a sound, a light signal and / or a mechanical vibration or the like. If the protective function additionally includes an inclination-dependent automatic shutdown of the suction drive and / or the tool drive, it is particularly advantageous if the warning device is activated in front of a shutdown - at a comparatively lower angle of inclination of the manual guide part. In this way, an interruption of the operating state due to a shutdown can be avoided and efficient operation of the wet cleaning device can be made possible.
In weiterer Ausgestaltung der Erfindung übermittelt die Steuereinrichtung in Abhängigkeit des erfassten Neigungswinkels ein drittes Steuersignal an die Warneinrichtung zur Aktivierung derselben. Das dritte Steuersignal kann binär oder analog sein. Das dritte Steuersignal kann drahtgebunden und/oder drahtlos an die Warneinrichtung übermittelt werden.In a further embodiment of the invention, the control device transmits a third control signal to the warning device in order to activate the same, depending on the detected angle of inclination. The third control signal can be binary or analog. The third control signal can be transmitted to the warning device in a wired and / or wireless manner.
In weiterer Ausgestaltung der Erfindung übermittelt die Steuereinrichtung das dritte Steuersignal bei Erreichen eines dritten Neigungswinkels. Sofern die Schutzfunktion zusätzlich eine neigungsabhängige automatische Abschaltung des Saug- und/oder des Werkzeugantriebs umfasst, ist es vorteilhaft, wenn der dritte Neigungswinkel - ausgehend von einer senkrechten Orientierung des Handführungsteils - geringer ist als der erste Neigungswinkel und/oder der zweite Neigungswinkel.In a further embodiment of the invention, the control device transmits the third control signal when a third inclination angle is reached. If the protective function additionally includes an inclination-dependent automatic shutdown of the suction and / or the tool drive, it is advantageous if the third inclination angle - starting from a vertical orientation of the manual guide part - is less than the first inclination angle and / or the second inclination angle.
In weiterer Ausgestaltung der Erfindung weist die Erfassungseinrichtung einen Beschleunigungssensor auf, der zur Erfassung des Neigungswinkels eingerichtet ist. Der Beschleunigungssensor ist vorzugsweise in Form eines piezoelektrischen Sensors ausgebildet. Solche piezoelektrischen Beschleunigungssensoren sind grundsätzlich bekannt. Vorzugsweise ist der Beschleunigungssensor am Handführungsteil angeordnet. Da die sich im Betriebszustand der Nassreinigungsvorrichtung ergebenden bewegungsbedingten Beschleunigungen im Vergleich zur Erdbeschleunigung vernachlässigbar klein sind, erlaubt diese Ausgestaltung der Erfindung eine hinreichend genaue Erfassung des Neigungswinkels.In a further embodiment of the invention, the detection device has an acceleration sensor which is set up to detect the angle of inclination. The acceleration sensor is preferably designed in the form of a piezoelectric sensor. Such piezoelectric acceleration sensors are generally known. The acceleration sensor is preferably arranged on the manual guide part. Since the movement-related accelerations that result in the operating state of the wet cleaning device are negligible in comparison to the acceleration due to gravity, this embodiment of the invention permits a sufficiently precise detection of the angle of inclination.
In weiterer Ausgestaltung der Erfindung ist die Erfassungseinrichtung zur Erfassung eines Füllstands des Aufnahmebehälters eingerichtet, wobei die Steuereinrichtung derart eingerichtet ist, dass die Schutzfunktion in Abhängigkeit des Füllstands steuerbar ist. Je nachdem, ob der Aufnahmebehälter einen vergleichsweise niedrigen oder einen vergleichsweise hohen Füllstand der Flüssigkeit aufweist, besteht die Gefahr eines neigungsbedingten Ansaugens von Flüssigkeit durch die Luftansaugöffnung erst bei vergleichsweise hohen bzw. bereits bei vergleichsweise geringen Neigungswinkeln des Handführungsteils. Diese Ausgestaltung der Erfindung trägt diesem Umstand Rechnung insoweit, als die Erfassungseinrichtung den Füllstand erfasst und die Schutzfunktion zusätzlich in Abhängigkeit des Füllstands gesteuert wird. Demnach ist die Steuereinrichtung derart eingerichtet, dass ein maximal zulässiger Neigungswinkel, bei dessen Erreichen die Schutzfunktion gesteuert wird, in Abhängigkeit des erfassten Füllstands bestimmbar ist. Dies ist eine besonders vorteilhafte Ausgestaltung der Erfindung.In a further embodiment of the invention, the detection device is set up to detect a fill level of the receptacle, the control device being set up in such a way that the protective function can be controlled as a function of the fill level. Depending on whether the receptacle has a comparatively low or a comparatively high fill level of the liquid, there is the risk of liquid being sucked in through the air suction opening only at comparatively high or already at comparatively low angles of inclination of the manual guide part. This embodiment of the invention takes this into account insofar as the detection device detects the fill level and the protective function is additionally controlled as a function of the fill level. Accordingly, the control device is set up in such a way that a maximum permissible angle of inclination, upon reaching which the protective function is controlled, can be determined as a function of the detected fill level. This is a particularly advantageous embodiment of the invention.
In weiterer Ausgestaltung der Erfindung weist die Erfassungseinrichtung einen Füllstandssensor auf, der zur Erfassung des Füllstands des Aufnahmebehälters eingerichtet ist. Solche Sensoren zur Füllstandsmessung sind grundsätzlich bekannt. Beispielsweise kann der Füllstandssensor in Form eines Schwimmers zur mechanischen Füllstandsmessung oder eines Füllstandsschalters zur kapazitiven Füllstandsmessung ausgebildet sein.In a further embodiment of the invention, the detection device has a fill level sensor which is set up to detect the fill level of the receptacle. Such sensors for level measurement are generally known. For example, the level sensor can be designed in the form of a float for mechanical level measurement or a level switch for capacitive level measurement.

Die Erfassungseinrichtung 25 weist einen Beschleunigungssensor 26 auf, der zur Erfassung des Neigungswinkels N eingerichtet ist. Der Beschleunigungssensor 26 ist in Form eines grundsätzlich bekannten piezoelektrischen Sensors ausgebildet. Der piezoelektrische Beschleunigungssensor 26 ermöglicht eine Erfassung des Neigungswinkels N in Bezug auf das Erdschwerefeld g, so dass der Neigungswinkel N vorliegend - vereinfacht ausgedrückt - eine absolute Neigung des Handführungsteils 2 und damit des Aufnahmebehälters 7 beschreibt. Bei einer nicht näher dargestellten Ausführungsform kann die Erfassungseinrichtung 25 zur Erfassung einer relativen Neigung des Handführungsteils 2 gegenüber dem Bodenteil 3 eingerichtet sein und zu diesem Zweck einen grundsätzlich bekannten mechanischen, elektrischen oder elektronischen Neigungssensor aufweisen, der beispielsweise im Bereich der Gelenkanordnung 4 angeordnet sein kann.The
Die Steuereinrichtung 20 ist mittels einer drahtgebundenen Signalleitung 27 mit der Erfassungseinrichtung 25 wirkverbunden. Anstelle einer drahtgebundenen Signalübertragung kann auch eine grundsätzlich bekannte drahtlose Signalübertragung zwischen der Erfassungseinrichtung 25 und der Steuereinrichtung 20 vorgesehen sein.The
Die Steuereinrichtung 20 ist vorliegend zur Steuerung der Schutzfunktion derart eingerichtet, dass in Abhängigkeit des erfassten Neigungswinkels N der Saugantrieb 9 und/oder Werkzeugantrieb 12 abschaltbar ist. Hierzu ist die Steuereinrichtung mittels entsprechender Signalleitungen 28, 29 mit dem Saugantrieb 9 bzw. dem Werkzeugantrieb 12 zur Signalübermittlung wirkverbunden. Dabei sendet die Steuereinrichtung 20 in Abhängigkeit des erfassten Neigungswinkels N ein erstes Steuersignal S1 an den Saugantrieb 9 zur Abschaltung desselben. In entsprechender Weise kann ein zweites Steuersignal S2 an den Werkzeugantrieb 12 zu dessen Abschaltung übermittelt werden.In the present case, the
Diese automatische neigungsabhängige Abschaltung der Antriebe 9, 12 kann gleichzeitig - d.h. bei Erreichen ein- und desselben vorgegebenen Neigungswinkels - oder gestaffelt - d.h. bei Erreichen unterschiedlicher Neigungswinkel - angesteuert werden. Vorliegend ist vorgesehen, dass bei Erreichen eines ersten Neigungswinkels N1 zunächst der Saugantrieb 9 abgeschaltet wird. Bei Erreichen eines zweiten Neigungswinkels N2 wird der Werkzeugantrieb 12 abgeschaltet. Der erste Neigungswinkel N1 und der zweite Neigungswinkel N2 sind vorliegend in grundsätzlich bekannter Weise elektronisch in einer Speichereinheit 30 der Steuereinrichtung 20 gespeichert. Eine Recheneinheit 31 der Steuereinrichtung 20 gleicht hierbei auf grundsätzlich bekannte Weise den erfassten Neigungswinkel N mit den gespeicherten Neigungswinkeln N1, N2 ab, wobei das entsprechende Steuersignal S1 bzw. S2 übermittelt wird, sobald der erfasste Neigungswinkel N dem entsprechend eingespeicherten Neigungswinkel N1 bzw. N2 entspricht. Der erste Neigungswinkel N1 ist vorliegend betragsmäßig kleiner als der zweite Neigungswinkel N2. Dies führt dazu, dass zum Schutz der Saugturbine 9 vor einem ungewollten Ansaugen von Flüssigkeit zunächst die Saugturbine 9 selbst abgeschaltet wird, sobald der erste Neigungswinkel N1 erreicht wird. Sofern sich eine Bedienperson hiervon unbeeindruckt zeigt und das Handführungsteil 2 über den ersten Neigungswinkel N1 hinaus weiter verschwenkt und der zweite Neigungswinkel N1 erreicht wird, wird zusätzlich der Werkzeugantrieb 12 abgeschaltet. Hierdurch kann eine nochmals verbesserte Betriebssicherheit der Nassreinigungsvorrichtung 1 erreicht werden. Grundsätzlich ist auch eine in hierzu umgekehrter Reihenfolge gestaffelte Abschaltung der Antriebe 9, 12 realisierbar.This automatic inclination-dependent shutdown of the
Wie weiter anhand
Vorliegend ist die Erfassungseinrichtung 25 zudem zur Erfassung des Füllstands H des Aufnahmebehälters 7 eingerichtet. Dabei ist die Steuereinrichtung 20 zusätzlich derart eingerichtet, dass die vorbeschriebene Schutzfunktion zusätzlich in Abhängigkeit des Füllstands H steuerbar ist. Zu diesem Zweck weist die Erfassungseinrichtung 25 einen Füllstandssensor 34 auf, der zur Erfassung des Füllstands H eingerichtet ist. Der Füllstandssensor 34 ist vorliegend in Form eines kapazitiven Sensors ausgebildet, der außerhalb des Aufnahmebehälters 7 in dem anhand
