Description
Die Erfindung betrifft ein Bodenpflegegerät mit einer verbesserten Zubehörerkennung.The invention relates to a floor care device with improved accessory recognition.
Bodenpflegegeräte weisen häufig eine Palette von abnehmbaren Zubehörteilen auf. Es gibt dabei rein passive Zubehörteile wie verschiedene Saugvorsätze oder -düsen, aber auch aktive Zubehörteile wie Saugdüsen mit motorisch angetrieben Bürsten und/oder einer Beleuchtung. Herkömmliche Bodenpflegegeräte können jedoch nicht automatisch erkennen, welche Zubehörteile ein Benutzer für einen Bodenpflegevorgang angebracht hat. Wird ein Zubehörteil vom Bodenpflegegerät nicht erkannt, so kann das Gerät sich nicht auf das entsprechende Zubehörteil einstellen, auch kann ein aktives Zubehörteil dann nicht variabel angesteuert werden.Floor care devices often have a range of detachable accessories. There are purely passive accessories such as various suction attachments or nozzles, but there are also active accessories such as suction nozzles with motor-driven brushes and/or lighting. However, conventional floor care devices cannot automatically recognize which accessories a user has attached for a floor care operation. If an accessory is not recognized by the floor care device, the device cannot adjust itself to the corresponding accessory, and an active accessory cannot then be variably controlled.
Aus der
Eine Erkennung von Zubehörteilen ist grundsätzlich mit einer dafür vorgesehenen zusätzlichen Daten- oder Busleitung denkbar. Das erhöht jedoch den Verkabelungsaufwand, den dafür benötigten Bauraum und somit auch die Kosten des Geräts. Diese Nachteile gilt es zu vermeiden.A detection of accessories is fundamentally conceivable with an additional data or bus line provided for this purpose. However, this increases the wiring effort, the space required for this and thus also the costs of the device. It is important to avoid these disadvantages.
Der Erfindung stellt sich somit das Problem, ein Bodenpflegegerät mit Zubehörerkennung bereitzustellen, das ohne eine zusätzliche Verkabelung für die Erkennung auskommt.The invention therefore faces the problem of providing a floor care device with accessory detection that does not require additional wiring for the detection.
Erfindungsgemäß wird dieses Problem durch ein Bodenpflegegerät mit den Merkmalen des Patentanspruchs 1 sowie ein System mit den Merkmalen des Anspruchs 6 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention, this problem is solved by a floor care device having the features of

- eine Steuereinheit;
- eine Schalteinrichtung, die dazu eingerichtet ist, die Gleichspannungsversorgungsschnittstelle zwischen einer ersten und einer zweiten Polarität umzuschalten;
- wobei die Steuereinheit dazu eingerichtet ist, mit der Schalteinrichtung die erste Polarität einzustellen, um ein Zubehörteil zu betreiben, oder mit der Schalteinrichtung die zweite Polarität einzustellen, um das Zubehörteil zu identifizieren.
- a DC power supply interface for detachable active accessories;
- a control unit;
- a switching device configured to switch the DC voltage supply interface between a first and a second polarity;
- wherein the control unit is arranged to set the first polarity with the switching device in order to operate an accessory or to set the second polarity with the switching device in order to identify the accessory.
In der Regel werden aktive Komponenten im Staubsaugerbereich mit einer Gleichspannung versorgt. Die Erfindung sieht eine Umpolung der Zubehörversorgung vor. Mit einem relativ geringen Schaltungsaufwand kann Zubehör über die Verkabelung, die für die Stromversorgung von aktiven Zubehörteilen ohnehin vorhanden ist, erkannt werden. Die Kosten, die deshalb mitgetragen werden müssen, sind relativ gering. Die Messung kann leistungsfrei erfolgen. Es können sowohl aktive als auch passiver Zubehörteile erkannt werden. Die Identifikation kann durch die Umpolung separat von dem Betrieb erfolgen.As a rule, active components in the vacuum cleaner area are supplied with direct current. The invention provides for polarity reversal of the supply of accessories. With a relatively small amount of circuitry, accessories can be detected via the wiring that is already present for the power supply of active accessories. The costs that have to be borne as a result are relatively low. The measurement can be performed power-free. Both active and passive accessories can be detected. The identification can be done separately from the operation by reversing the polarity.
Gemäß einer Ausführungsform umfasst die Gleichspannungsversorgungsschnittstelle eine 2-Draht-Leitung.According to one embodiment, the DC voltage supply interface includes a 2-wire line.
Aufgrund der mit der Erfindung vorgesehenen Umpolung genügt eine 2-Draht-Leitung für die beiden Anwendungsfälle "Betrieb aktiver Zubehörteile" und "Erfassung von aktiven/passiven Zubehörteilen".Due to the polarity reversal provided by the invention, a 2-wire line is sufficient for the two applications "operation of active accessories" and "detection of active/passive accessories".

Beispielsweise könnte bei einem Kondensator bzw. einer Spule die Zeit gemessen werden, nach der ein bestimmter Spannungspegel erreicht wird. Verschiedene Kondensatoren werden nach verschiedenen Zeiten aufgeladen. Eine Spule verzögert den Stromfluss.For example, in the case of a capacitor or a coil, the time after which a specific voltage level is reached could be measured. Different capacitors are charged after different times. A coil delays the flow of current.

Düsenbeleuchtung) die Messung/Erkennung nicht beeinflussen.The detection path and the power path (motor/lighting) can be addressed separately via appropriate components, so that the motor or other actuators (e.g. nozzle lighting) do not affect the measurement/detection.
