Abstract
Description
Die Erfindung betrifft ein selbstfahrendes Sauggerät zur automatisierten Reinigung einer Fläche mit mindestens einem Sensor zur Erfassung von Eigenschaften einer Umgebung des Sauggeräts sowie ein Betriebsverfahren für ein derartiges Sauggerät. The invention relates to a self-propelled suction device for automated cleaning of a surface with at least one sensor for detecting properties of an environment of the suction device and an operating method for such a suction device.
Derartige selbstfahrende Sauggeräte, auch Saugroboter genannt, dienen der automatisierten Reinigung von Flächen, ohne dass sie von einem Benutzer geschoben oder geführt werden müssen. Üblicherweise weist ein derartiges Sauggerät einen oder mehrere Sensoren auf, um die Bewegung des Geräts über die zu reinigende Fläche zu kontrollieren, beispielsweise um festen Hindernissen auszuweichen oder einen Absturz an Kanten, beispielsweise an Treppenstufen, zu vermeiden. Solche Sensoren können beispielsweise Tastsensoren sein, wie in der Druckschrift
Unabhängig davon, ob es sich um ein manuell geführtes oder ein automatisiert arbeitendes Sauggerät handelt, können mit einem derartigen Gerät nur dann Flüssigkeiten oder größere Feuchtigkeitsmengen aufgenommen werden, wenn die Geräte speziell dafür eingerichtet sind. Sind die Geräte nicht entsprechend eingerichtet, kann eine aufgenommene Flüssigkeitsmenge zu einer Zerstörung eines Filterbeutels oder einer Beschädigung des Motors des Sauggebläses führen. Um eine derartige Beschädigung zu verhindern, ist aus der Druckschrift
Der Erfindung stellt sich somit das Problem, ein selbstfahrendes Sauggerät der eingangs genannten Art bereit zu stellen, bei dem auch beim automatisierten Betrieb ein Eindringen von Flüssigkeit in das Sauggerät verhindert wird. The invention thus presents the problem to provide a self-propelled suction device of the type mentioned, in which the penetration of liquid into the suction device is prevented even during automated operation.
Erfindungsgemäß wird dieses Problem durch ein selbstfahrendes Sauggerät mit den Merkmalen von Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen sind in den abhängigen Ansprüchen angegeben. According to the invention this problem is solved by a self-propelled suction device with the features of claim 1. Advantageous embodiments and further developments are specified in the dependent claims.
Ein erfindungsgemäßes selbstfahrendes Sauggerät der eingangs genannten Art zeichnet sich dadurch aus, dass der mindestens eine Sensor dazu eingerichtet ist, sich auf der zu reinigenden Fläche befindende Flüssigkeit zu erkennen. Wird Flüssigkeit durch den Sensor bereits in der Umgebung, d.h. außerhalb des Sauggeräts erkannt, kann verhindert werden, dass die Flüssigkeit überhaupt in das Sauggerät eindringt und dort ggf. zu einer Beschädigung führt. An inventive self-propelled suction device of the type mentioned above is characterized in that the at least one sensor is adapted to be detected on the surface to be cleaned liquid. If liquid is already passing through the sensor in the environment, i. Detected outside of the suction device, it can be prevented that the liquid ever penetrates into the suction device and possibly leads to damage there.
In einer vorteilhaften Ausgestaltung weist das selbstfahrende Sauggerät eine Steuervorrichtung zur Auswertung des mindestens einen Sensors auf, wobei die Steuervorrichtung dazu eingerichtet ist, das Sauggerät so zu steuern, dass eine von dem mindestens einen Sensor detektierte Flüssigkeit nicht in einen Saugbereich des Sauggeräts gelangt. Bevorzugt ist die Steuervorrichtung dazu eingerichtet, einen Bereich der zu reinigenden Fläche, in dem Flüssigkeit detektiert wurde, zu umfahren. Alternativ oder zusätzlich ist die Steuervorrichtung bevorzugt dazu eingerichtet, nach einem Erkennen von Flüssigkeit eine Bewegungsrichtung des Sauggeräts umzukehren und/oder ein Sauggebläse zu stoppen und/oder Reinigungsvorrichtungen im Saugbereich anzuheben oder einzufahren. Die genannten Maßnahmen sind geeignet, nach dem Erkennen einer Flüssigkeit auch das Eindringen der Flüssigkeit in das Sauggerät zu verhindern. In an advantageous embodiment, the self-propelled suction device has a control device for evaluating the at least one sensor, wherein the control device is configured to control the suction device such that a liquid detected by the at least one sensor does not enter a suction region of the suction device. Preferably, the control device is configured to bypass a region of the surface to be cleaned in which liquid has been detected. Alternatively or additionally, the control device is preferably configured to reverse a movement direction of the suction device after a detection of liquid and / or to stop a suction blower and / or to lift or retract cleaning devices in the suction region. The measures mentioned are suitable for preventing the penetration of the liquid into the suction device after the detection of a liquid.
In einer weiteren vorteilhaften Ausgestaltung des selbstfahrenden Sauggeräts ist der mindestens eine Sensor ein optischer Sensor, bevorzugt eine Kamera oder ein IR-Reflexsensor. Eine Kamera ermöglicht vorteilhafterweise eine Fernerkennung von Flüssigkeiten. Entsprechend können Maßnahmen wie ein Umfahren der Flüssigkeiten ergriffen werden, bevor das Sauggerät überhaupt in den Bereich der Flüssigkeiten gelangt. Auch kann eine Kartierung von Bereichen mit Flüssigkeiten erfolgen und so Änderungen in der Ausdehnung der Bereiche erfasst werden. Dadurch ist eine Warnung vor Wasserschäden möglich. Besonders bevorzugt wird als Sensor eine Kamera verwendet, die zusätzlich zur Navigation des Sauggeräts dient. Ebenfalls besonders bevorzugt wird als Sensor ein IR-Reflexsensor verwendet, der zusätzlich ein Absturzsensor ist. Auf diese Weise können Komponenten des Sauggeräts mehrfach zu verschiedenen Zwecken genutzt werden, was sich positiv auf die Herstellungskosten auswirkt. In a further advantageous embodiment of the self-propelled suction device, the at least one sensor is an optical sensor, preferably a camera or an IR reflex sensor. A camera advantageously enables remote detection of liquids. Accordingly, measures such as a bypassing of the liquids can be taken before the suction device at all in the field of Liquids get. It is also possible to map areas with liquids and thus detect changes in the extent of the areas. As a result, a warning of water damage is possible. Particularly preferred as a sensor, a camera is used, which serves in addition to the navigation of the suction device. Also particularly preferably, an IR reflex sensor is used as the sensor, which is additionally a crash sensor. In this way, components of the suction device can be used several times for different purposes, which has a positive effect on the manufacturing costs.
In einer weiteren vorteilhaften Ausgestaltung des selbstfahrenden Sauggeräts ist der mindestens eine Sensor ein elektrischer Sensor und insbesondere ein Widerstandssensor oder ein kapazitiv oder induktiv arbeitender Sensor. Bevorzugt weist ein als Widerstandssensor ausgebildeter Sensor ein bodennah angeordnetes Kontaktpaar auf, wobei Kontakte des Kontaktpaars besonders bevorzugt zusätzlich als Ladekontakte für eine wieder aufladbare Batterie des Sauggeräts dienen. Eine Erkennung von Flüssigkeiten über einen derartigen elektrisch arbeitenden Sensor ist einfach und kostengünstig realisierbar. Bei Mehrfachnutzung von Kontakten als Sensor bzw. als Ladekontakt ergibt sich zudem ein weiterer Kostenvorteil. In a further advantageous embodiment of the self-propelled suction device, the at least one sensor is an electrical sensor and in particular a resistance sensor or a capacitively or inductively operating sensor. Preferably, a sensor designed as a resistance sensor has a contact pair arranged close to the ground, wherein contacts of the contact pair particularly preferably additionally serve as charging contacts for a rechargeable battery of the suction device. A detection of liquids via such an electrically operating sensor is simple and inexpensive to implement. With multiple use of contacts as a sensor or as a charging contact also results in a further cost advantage.
Ein erfindungsgemäßes Verfahren zum Betreiben eines selbstfahrenden Sauggeräts zur automatisierten Reinigung einer Fläche, das mindestens einen Sensor zur Erfassung von Eigenschaften seiner Umgebung aufweist, weist die folgenden Schritte auf: Es werden Informationen des mindestens einen Sensors eingelesen und zum Erkennen von Flüssigkeit, die sich auf einer zu reinigenden Fläche befindet, ausgewertet. Falls Flüssigkeit erkannt wird, wird das Sauggerät derart gesteuert, dass ein Eindringen der Flüssigkeit in einen Saugbereich des Sauggeräts verhindert wird. Bevorzugt wird nach Erkennen von Flüssigkeit eine Bewegungsrichtung des Sauggeräts umgekehrt und/oder ein Sauggebläse gestoppt und/oder es werden Reinigungsvorrichtungen im Saugbereich angehoben oder eingefahren. Es ergeben sich die im Zusammenhang mit dem Sauggerät zuvor beschriebenen Vorteile. An inventive method for operating a self-propelled vacuum cleaner for automated cleaning of a surface having at least one sensor for detecting properties of its environment, comprises the following steps: Information of the at least one sensor is read and for detecting liquid, which is located on a surface to be cleaned is evaluated. If liquid is detected, the suction device is controlled such that penetration of the liquid into a suction region of the suction device is prevented. Preferably, after detection of liquid, a direction of movement of the suction device is reversed and / or a suction fan is stopped and / or cleaning devices are raised or retracted in the suction region. This results in the advantages described above in connection with the suction device.
