Description

Die Erfindung betrifft ein Haushaltsreinigungsgerät, insbesondere einen Staubsauger, umfassend mindestens ein mit einem Grundkörper verbindbares Zubehör, mindestens einen ersten in dem Grundkörper angeordneten wiederaufladbaren Energiespeicher, mindestens einen weiteren in einem Zubehör angeordneten wiederaufladbaren Energiespeicher und mindestens ein von mindestens einem der wiederaufladbaren Energiespeicher mit Energie versorgbaren Verbraucher. Darüber hinaus betrifft die Erfindung eine Basisstation für ein Haushaltsreinigungsgerät.The invention relates to a household cleaning device, in particular a vacuum cleaner, comprising at least one accessory that can be connected to a base body, at least one first rechargeable energy store arranged in the base body, at least one further rechargeable energy store arranged in an accessory and at least one of at least one of the rechargeable energy stores that can be supplied with energy Consumer. The invention also relates to a base station for a household cleaning appliance.

Unter einem Haushaltsreinigungsgerät ist gemäß der vorliegenden Erfindung insbesondere ein Staubsauger, wie ein Handstaubsauger, zu verstehen. Ein Haushaltsreinigungsgerät weist einen Grundkörper und ein mit dem Grundkörper verbundenes oder verbindbares Zubehör auf. Der Grundkörper kann einen Griff für einen Benutzer umfassen oder der Griff kann an einer mit dem Grundkörper verbundenen Stange angeordnet sein.According to the present invention, a household cleaning appliance is to be understood in particular as a vacuum cleaner, such as a hand-held vacuum cleaner. A household cleaning appliance has a base body and accessories that are or can be connected to the base body. The main body can comprise a handle for a user or the handle can be arranged on a rod connected to the main body.

Unter einem Zubehör ist vorliegend insbesondere ein an den Grundkörper ankoppelbares oder fest verbundenes Element zu verstehen. Das Zubehör kann beispielsweise eine Saugeinheit bzw. Düseneinheit zum Reinigen von Oberflächen sein. Während des Betriebs eines Handstaubsaugers können dazu vorgesehene Kontaktflächen des Zubehörs, wie die Laufrollen und/oder ein Arbeitselement des Zubehörs, die zu reinigende Fläche kontaktieren.In the present case, an accessory is to be understood in particular as an element that can be coupled to or firmly connected to the base body. The accessory can be, for example, a suction unit or nozzle unit for cleaning surfaces. During the operation of a hand-held vacuum cleaner, contact surfaces of the accessories provided for this purpose, such as the rollers and / or a working element of the accessories, can contact the surface to be cleaned.

In dem Grundkörper ist insbesondere eine Saugvorrichtung angeordnet. Die Saugvorrichtung weist ein Arbeitselement in Form eines Sauggebläses auf, welches von einem elektrischen Verbraucher in Form eines Elektromotors angetrieben werden kann. Über die Saugvorrichtung können durch einen zwischen der Saugvorrichtung und dem Zubehör angeordneten Saugkanal Partikel angesaugt werden, die sich auf der zu reinigenden Oberfläche befinden.In particular, a suction device is arranged in the base body. The suction device has a working element in the form of a suction fan, which can be driven by an electrical consumer in the form of an electric motor. About the suction device can through a between the Suction device and the accessories arranged suction channel particles are sucked in, which are located on the surface to be cleaned.

Im Stand der Technik finden sich vermehrt Haushaltsreinigungsgeräte, bei denen in dem Grundkörper zur Energieversorgung des mindestens einen elektrischen Verbrauchers ein wiederaufladbarer elektrischer Energiespeicher angeordnet ist. Der Energiespeicher, wie ein Akkumulator, dient dazu, den mindestens einen Verbraucher mit elektrischer Energie zu versorgen. Beispielsweise kann der Elektromotor der Saugvorrichtung mit elektrischer Energie versorgt werden. Indem ein wiederaufladbarer elektrischer Energiespeicher im Grundkörper installiert ist, wird ein kabelloser und damit benutzerfreundlicher Betrieb eines Haushaltsreinigungsgeräts ermöglicht.In the prior art, there are increasing numbers of household cleaning devices in which a rechargeable electrical energy store is arranged in the base body for supplying energy to the at least one electrical consumer. The energy store, like an accumulator, is used to supply the at least one consumer with electrical energy. For example, the electric motor of the suction device can be supplied with electrical energy. By installing a rechargeable electrical energy store in the base body, wireless and thus user-friendly operation of a household cleaning device is made possible.

Ein Nachteil eines derartigen wiederaufladbaren Energiespeichers ist das hohe Gewicht des Energiespeichers. Aufgrund der Anordnung des Energiespeichers in dem Grundkörper erhöht sich das von einem Benutzer während des Betriebs des Handstaubsaugers zu tragende Gewicht. Somit verringert sich der Betriebskomfort des Handstaubsaugers. Deswegen wird im Stand der Technik in der Regel zu Gunsten eines geringeren Gewichts ein elektrischer Energiespeicher mit einer geringeren Kapazität eingesetzt.A disadvantage of such a rechargeable energy store is the high weight of the energy store. Due to the arrangement of the energy store in the base body, the weight to be carried by a user during operation of the hand-held vacuum cleaner increases. This reduces the convenience of the handheld vacuum cleaner. For this reason, in the prior art, an electrical energy store with a lower capacity is generally used in favor of a lower weight.

Darüber hinaus sind bei verbesserten Haushaltsreinigungsgeräten des Standes der Technik aktive Zubehöre vorgesehen, die einen weiteren wiederaufladbaren Energiespeicher umfassen. Der weitere wiederaufladbare Energiespeicher dient dazu, einen im Zubehör angeordneten elektrischen Verbraucher, wie ein Elektromotor für ein Arbeitselement und/oder ein Sensor, mit elektrischer Energie zu versorgen.In addition, in improved household cleaning devices of the prior art, active accessories are provided which comprise a further rechargeable energy store. The further rechargeable energy store is used to supply an electrical consumer arranged in the accessory, such as an electric motor for a working element and / or a sensor, with electrical energy.

Zwar erhöht sich bei derartigen Haushaltsreinigungsgeräten die insgesamt für die elektrischen Verbraucher des Haushaltsreinigungsgeräts zur Verfügung stehende elektrische Energie. Jedoch ist die zur Verfügung stehende elektrische Energie nicht flexibel verwendbar. Dies reduziert die Benutzerfreundlichkeit sowie die Leistungsfähigkeit des Haushaltsreinigungsgeräts. Ein Haushaltsreinigungsgerät gemäß dem Oberbegriff des Anspruchs 1 ist z.B. in JP-A-2015159841 offenbart.It is true that in such household cleaning devices the total electrical energy available for the electrical consumers of the household cleaning device increases. However, the available electrical energy is not flexible to use. This reduces the user friendliness and the efficiency of the household cleaning device. A household cleaning device according to the preamble of claim 1 is for example in JP-A-2015159841 disclosed.

Daher liegt der Erfindung die Aufgabe zugrunde, ein Haushaltsreinigungsgerät bereitzustellen, welches die Nachteile der bekannten Haushaltsreinigungsgeräte zumindest reduziert und insbesondere die Benutzerfreundlichkeit und die Leistungsfähigkeit des Haushaltsreinigungsgeräts verbessert.The invention is therefore based on the object of providing a household cleaning device which at least reduces the disadvantages of the known household cleaning devices and in particular improves the user friendliness and the performance of the household cleaning device.

Die Aufgabe wird gemäß einem ersten Aspekt der Erfindung durch ein Haushaltsreinigungsgerät gemäß dem Patentanspruch 1 gelöst. Das Haushaltsreinigungsgerät, insbesondere ein Staubsauger, umfasst mindestens ein mit einem Grundkörper zumindest verbindbares Zubehör. Das Haushaltsreinigungsgerät umfasst mindestens einen ersten in dem Grundkörper angeordneten wiederaufladbaren Energiespeicher. Das Haushaltsreinigungsgerät umfasst mindestens einen weiteren in dem Zubehör angeordneten wiederaufladbaren Energiespeicher. Das Haushaltsreinigungsgerät umfasst mindestens ein von mindestens einem der wiederaufladbaren Energiespeicher mit Energie versorgbaren Verbraucher. Das Haushaltsreinigungsgerät zeichnet sich dadurch aus, dass mindestens eine erste zwischen dem ersten wiederaufladbaren Energiespeicher und dem weiteren wiederaufladbaren Energiespeicher angeordnete Schaltereinheit vorgesehen ist. Die erste Schaltereinheit ist eingerichtet, den ersten wiederaufladbaren Energiespeicher und den weiteren wiederaufladbaren Energiespeicher in einer ersten Schaltstellung parallel zu verschalten und in einer zweiten Schaltstellung in Reihe zu verschalten.According to a first aspect of the invention, the object is achieved by a household cleaning appliance according to patent claim 1. The household cleaning appliance, in particular a vacuum cleaner, comprises at least one accessory that can at least be connected to a base body. The household cleaning appliance comprises at least one first rechargeable energy store arranged in the base body. The household cleaning device comprises at least one further rechargeable energy store arranged in the accessory. The household cleaning device comprises at least one consumer that can be supplied with energy by at least one of the rechargeable energy stores. The household cleaning appliance is characterized in that at least one first switch unit is provided, which is arranged between the first rechargeable energy store and the further rechargeable energy store. The first switch unit is set up to connect the first rechargeable energy store and the further rechargeable energy store in parallel in a first switch position and to connect them in series in a second switch position.

Indem im Gegensatz zum Stand der Technik eine Schaltereinheit vorgesehen ist, um den mindestens einen ersten wiederaufladbaren Energiespeicher des Grundkörpers und mindestens einen weiteren wiederaufladbaren Energiespeicher des Zubehörs flexibel miteinander zu verschalten, wird die Benutzerfreundlichkeit und die Leistungsfähigkeit des Haushaltsreinigungsgeräts verbessert. Insbesondere verbessert sich die Benutzerfreundlichkeit und die Leistungsfähigkeit dadurch, dass bei Bedarf durch eine Parallelschaltung der zumindest zwei Energiespeicher eine Kapazitätserweiterung (längere Betriebsdauer) und bei Bedarf durch eine Reihenschaltung der zumindest zwei Energiespeicher eine Erhöhung der maximal zur Verfügung stehenden Leistung (durch eine Spannungserhöhung) bereitgestellt werden kann. Zudem verteilt sich das Gewicht des Energiespeichers des Zubehörs vorzugsweise unmittelbar auf die Kontaktflächen des Zubehörs, wie dessen Laufrolle/n und/oder Arbeitselement/e.In that, in contrast to the prior art, a switch unit is provided to flexibly interconnect the at least one first rechargeable energy store of the base body and at least one further rechargeable energy store of the accessories, the user-friendliness and the performance of the household cleaning device are improved. In particular, the user-friendliness and the performance are improved in that If required, a parallel connection of the at least two energy stores can provide a capacity expansion (longer operating time) and, if necessary, a series connection of the at least two energy stores can provide an increase in the maximum available power (through an increase in voltage). In addition, the weight of the energy store of the accessory is preferably distributed directly over the contact surfaces of the accessory, such as its roller (s) and / or working element (s).

Das Haushaltsreinigungsgerät kann insbesondere ein Staubsauger sein. Das Haushaltsreinigungsgerät umfasst einen Grundkörper, an den ein oder mehrere (unterschiedliche) Zubehör/e zumindest ankoppelbar sind. Ein Zubehör ist insbesondere ein ankoppelbares Zubehörelement. Vorzugsweise kann das mindestens eine Zubehör ein aktives Zubehör (z.B. aktive Düse) oder ein passives Zubehör (z.B. passive Düse und/oder ein Verlängerungsschlauch mit Handhabungsgriff) sein. Ein aktives Zubehör weist mindestens einen elektrischen Verbraucher auf, wie einen elektrisch betriebenen Sensor und/oder einen elektrisch betriebenen Aktor. Ein Aktor kann beispielsweise ein Elektromotor zum Betreiben von einem Arbeitselement des Haushaltsreinigungsgeräts oder zum Betreiben von einem Arbeitselement des Zubehörs sein. Ein passives Zubehör umfasst hingegen keine elektrischen Verbraucher.The household cleaning device can in particular be a vacuum cleaner. The household cleaning appliance comprises a base body to which one or more (different) accessories can at least be coupled. An accessory is, in particular, an accessory element that can be coupled. The at least one accessory can preferably be an active accessory (e.g. an active nozzle) or a passive accessory (e.g. a passive nozzle and / or an extension hose with a handle). An active accessory has at least one electrical consumer, such as an electrically operated sensor and / or an electrically operated actuator. An actuator can be, for example, an electric motor for operating a working element of the household cleaning appliance or for operating a working element of the accessory. A passive accessory, on the other hand, does not include any electrical consumers.

Das Haushaltsreinigungsgerät umfasst mindestens zwei wiederaufladbare elektrische Energiespeicher. Ein wiederaufladbarer Energiespeicher ist eingerichtet, elektrische Energie zu speichern und bei Bedarf an mindestens einen elektrischen Verbraucher abzugeben. Vorzugsweise ist ein wiederaufladbarer Energiespeicher in Form eines Akkumulators gebildet.The household cleaning device comprises at least two rechargeable electrical energy stores. A rechargeable energy store is set up to store electrical energy and, if necessary, to deliver it to at least one electrical consumer. A rechargeable energy store is preferably designed in the form of an accumulator.

Ein erster wiederaufladbarer Energiespeicher ist im Grundkörper angeordnet und ein weiterer wiederaufladbarer Energiespeicher ist in dem vorzugsweise ankoppelbaren Zubehör angeordnet. Indem ein zusätzlicher Energiespeicher in dem Zubehör des Haushaltsreinigungsgeräts angeordnet ist, kann insbesondere ohne eine Erhöhung des Gewichts des Grundkörpers die zur Verfügung stehende elektrische Energie für den Betrieb des Haushaltsreinigungsgeräts und/oder des aktiven Zubehörs erhöht werden.A first rechargeable energy store is arranged in the base body and a further rechargeable energy store is arranged in the accessories that can preferably be coupled. By arranging an additional energy store in the accessories of the household cleaning device, it is possible in particular without an increase the weight of the base body, the available electrical energy for the operation of the household cleaning device and / or the active accessories can be increased.

Um die zur Verfügung stehende elektrische Energie flexibel und bedarfsoptimiert zu nutzen, ist eine erste Schaltereinheit vorgesehen. Die erste Schaltereinheit weist Schaltmittel auf, um die zumindest zwei vorgesehenen wiederaufladbaren Energiespeicher parallel oder in Reihe zu verschalten. In einer ersten Schaltstellung sind die wiederaufladbaren Energiespeicher parallel verschaltet und in einer zweiten Schaltstellung sind die wiederaufladbaren Energiespeicher in Reihe geschaltet. Hierdurch kann abhängig von dem augenblicklichen Bedarf die zur Verfügung stehende maximale Leistung erhört oder die Betriebsdauer des Haushaltsreinigungsgeräts verlängert werden.A first switch unit is provided in order to use the available electrical energy flexibly and in a demand-optimized manner. The first switch unit has switching means in order to connect the at least two provided rechargeable energy stores in parallel or in series. In a first switch position the rechargeable energy stores are connected in parallel and in a second switch position the rechargeable energy stores are connected in series. In this way, depending on the current demand, the maximum available power can be increased or the operating time of the household cleaning appliance can be extended.

Gemäß der Erfindung umfasst das Haushaltseinigungsgerät eine Steuereinheit eingerichtet zum Steuern der ersten Schaltereinheit. Gemäß einer bevorzugten Ausführungsform kann das Haushaltseinigungsgerät eine Steuereinheit eingerichtet zum Steuern der ersten Schaltereinheit abhängig von einem Betriebszustand des Haushaltsreinigungsgeräts umfassen. Beispielsweise kann in der Steuereinheit implementiert sein, dass bei mindestens einem ersten detektierbaren Betriebszustand die erste Schaltereinheit (stets) in die erste Schaltstellung und/oder bei mindestens einem weiteren Betriebszustand (stets) in die zweite Schaltstellung gesetzt wird. In dem der augenblickliche Betriebszustand bei der Verschaltung berücksichtigt wird, kann in automatischer Weise die Benutzerfreundlichkeit verbessert werden.According to the invention, the household cleaning appliance comprises a control unit designed to control the first switch unit. According to a preferred embodiment, the household cleaning appliance can comprise a control unit set up to control the first switch unit as a function of an operating state of the household cleaning appliance. For example, it can be implemented in the control unit that in at least one first detectable operating state the first switch unit is (always) set in the first switching position and / or in at least one further operating state (always) in the second switching position. If the current operating state is taken into account during the interconnection, the user-friendliness can be improved in an automatic manner.

Die Steuereinheit zum Steuern der ersten Schaltereinheit ist abhängig von der erfassten Zubehörart eines mit dem Haushaltsreinigungsgerät verbundenen Zubehörs eingerichtet. Aufgrund der Art eines Zubehörs und insbesondere der damit verbundenen Verwendungsbestimmung kann z.B. ein vorbestimmter Betriebsmodus die erste Schaltereinheit derart steuern, dass diese in die erste oder zweite Schaltstellung gesetzt wird. Dies ermöglicht es beispielsweise, dass ein zum Zweck einer Überbodenreinigung mit dem Grundkörper des Haushaltsreinigungsgeräts verbundener Saugschlauch mit einer passiven Saugdüse, die einen weiteren wiederaufladbaren Energiespeicher aufweist, die durch seine Verwendung strömungstechnisch bedingten Saugleistungsverluste zu kompensieren, indem der erste Betriebsmodus bereitgestellt wird, bei dem die erste Schaltereinheit die zumindest zwei wiederaufladbaren Energiespeicher in Reihe zueinander schaltet und die dadurch erhöhte Saugleistung die hinzugekommenen Verluste ausgleicht.The control unit for controlling the first switch unit is set up as a function of the detected type of accessory of an accessory connected to the household cleaning appliance. Due to the type of accessory and, in particular, the associated intended use For example, a predetermined operating mode can control the first switch unit in such a way that it is set to the first or second switch position. This makes it possible, for example, that a suction hose connected to the main body of the household cleaning device for the purpose of cleaning the floor, with a passive suction nozzle that has a further rechargeable energy storage device, to compensate for the suction power losses caused by its use by providing the first operating mode in which the The first switch unit connects the at least two rechargeable energy stores in series with one another and the resulting increased suction power compensates for the additional losses.

Vorzugsweise kann die Steuereinheit eingerichtet sein, die erste Schaltereinheit in Abhängigkeit des Zustands des ersten wiederaufladbaren Energiespeichers und/oder des Zustands des weiteren wiederaufladbaren Energiespeichers zu steuern. Der Zustand kann insbesondere der augenblickliche Ladungszustand von dem ersten wiederaufladbaren Energiespeicher, vom dem weiteren wiederaufladbaren Energiespeicher und/oder von den zumindest zwei wiederaufladbaren Energiespeichern sein. Indem die Steuereinheit die erste Schaltereinheit abhängig von einem (augenblicklichen) Ladezustand eines wiederaufladbaren Energiespeichers steuert, kann insbesondere die zur Verfügung stehende Betriebsdauer des Haushaltsreinigungsgerät erhöht werden.The control unit can preferably be set up to control the first switch unit as a function of the state of the first rechargeable energy store and / or the state of the further rechargeable energy store. The state can in particular be the instantaneous charge state of the first rechargeable energy store, of the further rechargeable energy store and / or of the at least two rechargeable energy stores. Since the control unit controls the first switch unit as a function of an (instantaneous) charge state of a rechargeable energy store, the available operating time of the household cleaning appliance can in particular be increased.

Die Steuereinheit kann zumindest teilweise als Hardwaremodul und/oder zumindest teilweise als Softwaremodul gebildet sein.The control unit can be formed at least partially as a hardware module and / or at least partially as a software module.

Gemäß einer besonders bevorzugten Ausführungsform kann mindestens eine Erfassungseinheit zum Erfassen des Ladezustands des ersten wiederaufladbaren Energiespeichers und/oder zum Erfassen des Ladezustands des weiteren wiederaufladbaren Energiespeichers vorgesehen sein. Es versteht sich, dass auch zwei (oder mehr) separate Erfassungseinheiten vorgesehen sein können. Eine Erfassungseinheit kann ein Messmodul zum Bestimmen des augenblicklichen Ladezustands eines wiederaufladbaren Energiespeichers umfassen. Das Messmodul kann beispielsweise eine chemische, spannungsabhängige, Strom-integrative, druckabhängige oder Akkumulator-Impedanz Messung durchführen. Die mindestens eine Erfassungseinheit kann eine Kommunikationsverbindung zu der Steuereinheit aufweisen und der Steuereinheit den gemessenen Ladezustand zur Verfügung stellen.According to a particularly preferred embodiment, at least one detection unit can be provided for detecting the state of charge of the first rechargeable energy store and / or for detecting the state of charge of the further rechargeable energy store. It goes without saying that two (or more) separate detection units can also be provided. A detection unit can be a measurement module for determining the instantaneous Include the state of charge of a rechargeable energy store. The measuring module can, for example, carry out a chemical, voltage-dependent, current-integrative, pressure-dependent or accumulator impedance measurement. The at least one detection unit can have a communication connection to the control unit and provide the control unit with the measured state of charge.

Die Steuereinheit kann eingerichtet sein, bei Detektion eines Unterschreitens eines Vergleichsladezustands durch den mindestens einen erfassten Ladezustand die erste Schaltereinheit derart anzusteuern, dass der erste wiederaufladbare Energiespeicher und der weitere wiederaufladbaren Energiespeicher parallel verschaltet sind. Beispielsweise kann ein erster Vergleichsladezustand (z.B. zwischen 10 und 50 %) für den ersten wiederaufladbaren Energiespeicher des Grundkörpers vorgegeben sein. Unterschreitet der augenblickliche Ladezustand des ersten wiederaufladbaren Energiespeichers des Grundkörpers diesen ersten Vergleichsladezustand, kann insbesondere zur Verlängerung der Betriebsdauer automatisch eine parallele Verschaltung des ersten wiederaufladbaren Energiespeichers des Grundkörpers mit dem weiteren wiederaufladbaren Energiespeichers des Zubehörs bewirkt werden. Alternativ oder zusätzlich kann ein weiterer Vergleichsladezustand (z.B. zwischen 10 und 50 %) für den weiteren wiederaufladbaren Energiespeicher des Zubehörs vorgegeben sein. Auch hier kann vorgesehen sein, dass bei einem Unterschreiten des weiteren Vergleichsladezustands durch den augenblicklichen Ladezustand des weiteren wiederaufladbaren Energiespeichers des Zubehörs insbesondere zur Verlängerung der Betriebsdauer automatisch eine parallele Verschaltung des ersten Energiespeichers des Grundkörpers mit dem weiteren Energiespeichers des Zubehörs bewirkt wird.The control unit can be set up to control the first switch unit upon detection of the at least one detected state of charge falling below a comparison state of charge in such a way that the first rechargeable energy store and the further rechargeable energy store are connected in parallel. For example, a first comparison state of charge (e.g. between 10 and 50%) can be specified for the first rechargeable energy store of the base body. If the current state of charge of the first rechargeable energy store of the base body falls below this first comparison state of charge, a parallel connection of the first rechargeable energy store of the base body with the further rechargeable energy store of the accessories can be effected automatically, in particular to extend the operating time. As an alternative or in addition, a further comparison state of charge (e.g. between 10 and 50%) can be specified for the further rechargeable energy store of the accessories. Here, too, it can be provided that if the current state of charge of the further rechargeable energy store of the accessories falls below the further comparison state of charge, a parallel connection of the first energy store of the base body with the further energy store of the accessory is automatically effected, in particular to extend the operating time.

Bei einer alternativen oder vorzugsweise zusätzlichen Ausführungsform kann die Steuereinheit eingerichtet sein, die erste Schaltereinheit in Abhängigkeit von mindestens einem Betriebsmodus zu steuern. Ein Haushaltsreinigungsgerät kann vorzugsweise in verschiedenen Betriebsmodi betrieben werden. Die Betriebsmodi können sich beispielsweise dadurch unterscheiden, dass einem elektrischen Verbraucher eine unterschiedliche maximale Leistung zur Verfügung gestellt wird. Beispielsweise kann in einem ersten Betriebsmodus ein Elektromotor für ein Sauggebläse mit einer höheren Drehzahl (z.B. bis 150.000 min-1) als in einem weiteren Betriebsmodus betrieben werden, um eine besonders hohe Saugleistung zur Verfügung zu stellen. Erfindungsgemäß kann der erste Betriebsmodus bereitgestellt werden, indem die erste Schaltereinheit die zumindest zwei wiederaufladbaren Energiespeicher in Reihe zueinander schaltet. Die maximal zur Verfügung stehende Betriebsspannung von z.B. 24 V kann insbesondere zwischen 50 % und 100 % auf bis zu 48 V erhöht werden. Dies ermöglicht es beispielsweise, einen entsprechend ausgelegten Motor mit einer erhöhten Drehzahl zu betreiben. Hierzu kann die Steuereinheit einen entsprechenden ersten Betriebsmodus detektieren und die erste Schaltereinheit abhängig von dem detektierten Betriebsmodus ansteuern. In einem weiteren (Spar-)Betriebsmodus kann der Elektromotor mit niedrigeren Drehzahlen (geringerer max. Leistung bzw. Betriebsspannung) betrieben werden, um z.B. Energie zu sparen. Bei Detektion des weiteren Betriebsmodus kann die Steuereinheit die erste Schaltereinheit veranlassen, die zumindest zwei wiederaufladbaren Energiespeicher parallel zu verschalten.In an alternative or preferably additional embodiment, the control unit can be set up to control the first switch unit as a function of at least one operating mode. A household cleaning appliance can preferably be operated in different operating modes. The operating modes can differ, for example, in that an electrical A different maximum power is made available to consumers. For example, in a first operating mode, an electric motor for a suction fan at a higher speed (for example up to 150,000 min -1) can be operated as in a further operating mode, in order to provide a particularly high suction power is available. According to the invention, the first operating mode can be provided in that the first switch unit switches the at least two rechargeable energy stores in series with one another. The maximum available operating voltage of 24 V, for example, can be increased between 50% and 100% up to 48 V in particular. This makes it possible, for example, to operate a correspondingly designed motor at an increased speed. For this purpose, the control unit can detect a corresponding first operating mode and control the first switch unit as a function of the detected operating mode. In a further (economy) operating mode, the electric motor can be operated at lower speeds (lower maximum power or operating voltage) in order to save energy, for example. Upon detection of the further operating mode, the control unit can cause the first switch unit to connect the at least two rechargeable energy stores in parallel.

Der (gewünschte) Betriebsmodus kann zum Beispiel von einem Benutzer über eine Benutzerschnittstelle an dem Haushaltsreinigungsgerät vorgegeben werden. Alternativ oder zusätzlich kann das Haushaltsreinigungsgerät einen oder mehrere Sensor/en umfassen. Ein Sensor, wie ein Ultraschall-Sensor, kann insbesondere in dem Zubehör angeordnet sein. Der mindestens eine Sensor kann beispielsweise die augenblicklich zu reinigende Oberflächenart oder den Verschmutzungsgrad des augenblicklich zu reinigenden Oberfläche detektieren. Je nach detektierter Bodenart und/oder Verschmutzungsgrad kann eine Auswerteeinheit entsprechend vorgegebener Regeln den optimalen Betriebsmodus bestimmen. Die Steuereinheit kann abhängig von dem daraufhin automatisch eingestellten Betriebsmodus die erste Schaltereinheit steuern und veranlassen, dass die erste Schaltereinheit in die erste oder zweite Schaltstellung gesetzt wird.The (desired) operating mode can, for example, be specified by a user via a user interface on the household cleaning appliance. As an alternative or in addition, the household cleaning appliance can comprise one or more sensors. A sensor, such as an ultrasonic sensor, can in particular be arranged in the accessory. The at least one sensor can, for example, detect the type of surface to be cleaned at the moment or the degree of soiling of the surface to be cleaned at the moment. Depending on the type of soil detected and / or the degree of soiling, an evaluation unit can determine the optimal operating mode in accordance with predetermined rules. Depending on the operating mode that is then automatically set, the control unit can control the first switch unit and cause the first switch unit to be set to the first or second switch position.

Gemäß einer weiteren Ausführungsform kann zusätzlich vorgesehen sein, dass die erste Schaltereinheit eingerichtet ist, in einem dritten Schaltzustand den mindestens einen Verbraucher nur mit dem weiteren wiederaufladbaren Energiespeicher des Zubehörs zu verschalten. Die erste Schaltereinheit kann derart steuerbar sein, dass nur der weitere wiederaufladbare elektrische Energiespeicher des Zubehörs den mindestens einen Verbraucher, wie einen Elektromotor des Grundkörpers, mit elektrischer Energie versorgt. Beispielsweise kann die Steuereinheit derart programmiert sein, dass z.B. bis zu einem vorgegebenen zweiten Vergleichsladezustand (z.B. 10 bis 50 %) ausschließlich der weitere wiederaufladbare elektrische Energiespeicher des Zubehörs zur Versorgung des mindestens einen elektrischen Verbrauchers des Haushaltsreinigungsgeräts verwendet wird. Insbesondere bei einem abnehmbaren Zubehör besteht der Vorteil darin, dass das Zubehör mit einem entladenen Energiespeicher durch ein anderes Zubehör mit geladenem Energiespeicher ersetzt werden kann. Mit anderen Worten kann durch einen Austausch der Zubehöre ein Energiespeicheraustausch durchgeführt werden. In einfacher Weise kann so die Betriebsdauer des Haushaltsreinigungsgeräts noch weiter verbessert werden.According to a further embodiment, it can additionally be provided that the first switch unit is set up, in a third switching state, to connect the at least one consumer only to the further rechargeable energy store of the accessory. The first switch unit can be controllable in such a way that only the further rechargeable electrical energy store of the accessory supplies the at least one consumer, such as an electric motor of the base body, with electrical energy. For example, the control unit can be programmed in such a way that, for example, up to a predefined second comparison state of charge (e.g. 10 to 50%), only the additional rechargeable electrical energy store of the accessories is used to supply the at least one electrical consumer of the household cleaning appliance. Particularly in the case of a removable accessory, the advantage is that the accessory with a discharged energy store can be replaced by another accessory with a charged energy store. In other words, an exchange of the energy storage device can be carried out by exchanging the accessories. In this way, the service life of the household cleaning appliance can be improved even further in a simple manner.

Ein Haushaltsreinigungsgerät kann über mindestens ein fest verbundenes Zubehör verfügen. Mit anderen Worten ist in diesem Fall das Zubehör nicht von einem Benutzer (ohne erheblichen Montageaufwand) austauschbar. Vorzugsweise kann das Zubehör abnehmbar mit dem Grundkörper verbunden sein. Abnehmbar bedeutet insbesondere, dass mit einer (einfachen) Benutzeraktion das Zubehör von einem Grundkörper getrennt und beispielsweise durch ein weiteres Zubehör ersetzt werden kann.A household cleaning device can have at least one permanently connected accessory. In other words, in this case the accessories cannot be exchanged by a user (without considerable installation effort). The accessories can preferably be detachably connected to the base body. Removable means in particular that with a (simple) user action the accessories can be separated from a base body and, for example, replaced by another accessory.

Das Zubehör kann vorzugsweise mindestens einen elektrischen Ladeanschluss umfassen. Indem ein Zubehör zudem über einen eigenen Ladeanschluss verfügt, kann der wiederaufladbare Energiespeicher des Zubehörs unabhängig von dem Grundkörper eines Haushaltsreinigungsgeräts wiederaufgeladen werden. Der Ladeanschluss kann zu einem Ladeanschluss eines Lademoduls einer Basisstation korrespondieren. Alternativ kann das Lademodul in dem Zubehör integriert sein. Dann kann der Ladeanschluss beispielsweise zum Anschließen eines Kabels mit einem Stecker ausgebildet sein.The accessories can preferably include at least one electrical charging connection. Since an accessory also has its own charging connection, the rechargeable energy store of the accessory can be recharged independently of the main body of a household cleaning device. The charging connection can become a charging connection of a charging module of a base station correspond. Alternatively, the charging module can be integrated in the accessory. The charging connection can then be designed, for example, to connect a cable with a plug.

Vorzugsweise kann bei einem abnehmbar gebildeten Zubehör eine Steckverbindung eingerichtet zur Herstellung einer elektrischen Verbindung zwischen dem weiteren wiederaufladbaren Energiespeicher des Zubehörs und dem ersten wiederaufladbaren Energiespeicher des Grundkörpers vorgesehen sein. Beispielsweise weist das Zubehör ein zu einem Steckelement (z.B. Stecker) des Grundkörpers korrespondierendes Steckelement (z.B. Steckdose) auf. Die elektrische Verbindung kann genutzt werden, um elektrische Energie von dem Zubehör zu einem Verbraucher im Grundkörper und/oder um elektrische Energie von dem Grundkörper zu einem Verbraucher im Zubehör zu übertragen. Zwischen einem Verbraucher des Grundkörpers und einem weiteren wiederaufladbaren Energiespeicher des Zubehörs kann beispielsweise ein elektrisches Kabel mit der Steckverbindung vorgesehen sein.In the case of an accessory that is designed to be removable, a plug-in connection can preferably be provided to establish an electrical connection between the further rechargeable energy store of the accessory and the first rechargeable energy store of the base body. For example, the accessory has a plug-in element (e.g. socket) that corresponds to a plug-in element (e.g. plug) of the base body. The electrical connection can be used to transfer electrical energy from the accessory to a consumer in the base body and / or to transmit electrical energy from the base body to a consumer in the accessory. For example, an electrical cable with the plug connection can be provided between a consumer of the base body and a further rechargeable energy store of the accessories.

Wie bereits beschrieben wurde, kann der mindestens eine elektrische Verbraucher ein elektrisch betriebener Sensor und/oder Aktor sein. Der mindestens eine Verbraucher kann vorzugsweise ein Elektromotor sein. Der Elektromotor kann in dem Grundkörper zum Antreiben von mindestens einem in dem Grundkörper angeordneten Arbeitselement angeordnet sein. Das mindestens eine in dem Grundkörper angeordnete Arbeitselement kann ein Sauggebläse sein, um einen Luftstrom zum Ansaugen von Partikeln zu erzeugen, die sich z.B. auf einer zu reinigenden Oberfläche befinden. Das Sauggebläse wird vorzugsweise von dem elektrischen Antrieb bzw. Elektromotor angetrieben.As already described, the at least one electrical consumer can be an electrically operated sensor and / or actuator. The at least one consumer can preferably be an electric motor. The electric motor can be arranged in the main body for driving at least one working element arranged in the main body. The at least one working element arranged in the base body can be a suction fan in order to generate an air flow for sucking in particles which are located, for example, on a surface to be cleaned. The suction fan is preferably driven by the electric drive or electric motor.

Grundsätzlich kann ein Zubehör gemäß der Erfindung ein passives oder aktives Zubehör sein. Unter einem passiven Zubehör ist ein Zubehör zu verstehen, dass keine elektrisch betriebenen Verbraucher umfasst. Unter einem aktiven Zubehör ist vorliegend ein Zubehör mit mindestens einem elektrisch betriebenen Verbraucher, wie ein elektrisch betriebener Sensor oder ein Elektromotor, zu verstehen. Beispielsweise kann der mindestens eine Elektromotor in dem Zubehör zum Antreiben von mindestens einem in dem Zubehör angeordneten Arbeitselement angeordnet sein. Das Zubehör kann eine elektrische Verbindung zwischen dem weiteren wiederaufladbaren elektrischen Energiespeicher und dem Elektromotor des Zubehörs aufweisen. Der Elektromotor kann beispielsweise als Arbeitselement eine Bürstenvorrichtung, eine Wischvorrichtung oder eine Poliervorrichtung antreiben. Es versteht sich, dass ein Zubehör mehr als einen Elektromotor, Sensor und/oder mehr als ein Arbeitselement umfassen kann.In principle, an accessory according to the invention can be a passive or active accessory. A passive accessory is to be understood as an accessory that does not include any electrically operated loads. In the present case, an active accessory is to be understood as an accessory with at least one electrically operated consumer, such as an electrically operated sensor or an electric motor. For example, the at least one electric motor can be arranged in the accessory for driving at least one working element arranged in the accessory. The accessory can have an electrical connection between the further rechargeable electrical energy store and the electric motor of the accessory. The electric motor can for example drive a brush device, a wiping device or a polishing device as a working element. It goes without saying that an accessory can comprise more than one electric motor, sensor and / or more than one working element.

Um eine direkte elektrische Verbindung zwischen einem Elektromotor des Zubehörs und einem weiteren wiederaufladbaren Energiespeicher des Zubehörs herzustellen, gleichzeitig aber bei Bedarf eine elektrische Verbindung beispielsweise mit einem weiteren Elektromotor des Grundkörpers herzustellen, kann vorzugsweise eine zweite Schaltereinheit vorgesehen sein. Gemäß einer bevorzugten Ausführungsform kann die zweite Schaltereinheit in dem Zubehör angeordnet sein. Die zweite Schaltereinheit kann von der Steuereinheit steuerbar sein, derart, dass nur der weitere wiederaufladbare elektrische Energiespeicher des Zubehörs den Verbraucher des Zubehörs mit elektrischer Energie versorgt. Beispielsweise kann die Steuereinheit abhängig von Zustandsdaten der wiederaufladbaren Energiespeicher, Benutzereingaben und/oder festvorgebbaren Regeln eine elektrische Verbindung derart herstellen, dass ein Verbraucher des Zubehörs ausschließlich von dem weiteren Energiespeicher des Zubehörs mit elektrischer Energie versorgt wird.A second switch unit can preferably be provided in order to establish a direct electrical connection between an electric motor of the accessory and a further rechargeable energy store of the accessory, but at the same time, if necessary, to establish an electrical connection with, for example, a further electric motor of the base body. According to a preferred embodiment, the second switch unit can be arranged in the accessory. The second switch unit can be controllable by the control unit in such a way that only the further rechargeable electrical energy store of the accessory supplies the consumer of the accessory with electrical energy. For example, the control unit can establish an electrical connection depending on status data of the rechargeable energy storage device, user inputs and / or permanently predeterminable rules in such a way that a consumer of the accessories is supplied with electrical energy exclusively by the additional energy storage device of the accessories.

Das Zubehör kann ein passives Zubehör in Form einer Kombinationsdüse sein. Die Kombinationsdüse für Hart- und Teppichböden kann manuell umschaltbar sein. Auch kann das Zubehör eine Parkettdüse sein. Bei einer Parkettdüse wirkt sich das zusätzliche Gewicht eines in der Parkettdüse angeordneten Akkumulators besonders vorteilhaft aus, da die Borsten bzw. Dichtelemente der Parkettdüse stärker an das zu reinigende Parkett angedrückt werden. Weitere beispielhafte und nicht abschließende Zubehöre, die erfindungsgemäß mit einem zusätzlichen Akkumulator ausgestattet sein können, sind Hartbodendüsen, Elektrobürsten, Polierbürsten, Wischdüse, Teppichdüse und Polsterdüsen sowie den Arbeitsradius vergrößernde Saugschläuche.The accessory can be a passive accessory in the form of a combination nozzle. The combination nozzle for hard and carpeted floors can be switched manually. The accessory can also be a parquet nozzle. In the case of a parquet nozzle, the additional weight of an accumulator arranged in the parquet nozzle has a particularly advantageous effect, since the bristles or sealing elements of the parquet nozzle are pressed more strongly against the parquet to be cleaned. Further exemplary and non-exhaustive accessories that are equipped according to the invention with an additional accumulator hard floor nozzles, electric brushes, polishing brushes, wiping nozzles, carpet nozzles and upholstery nozzles as well as suction hoses that enlarge the working radius.

Es versteht sich, dass das Haushaltsreinigungsgerät zusätzlich ein Netzkabel zum Aufladen des mindestens einen ersten wiederaufladbaren Energiespeichers und/oder zum optionalen kabelgebundenen Betrieb des Haushaltsreinigungsgeräts aufweisen kann.It goes without saying that the household cleaning device can additionally have a power cord for charging the at least one first rechargeable energy store and / or for the optional wired operation of the household cleaning device.

Ein weiterer Aspekt der Erfindung ist eine Basisstation für ein Haushaltsreinigungsgerät, insbesondere für ein zuvor beschriebenes Haushaltsreinigungsgerät, umfassend ein erstes Lademodul mit einem ersten zu einem weiteren Ladeanschluss eines Grundkörpers eines Haushaltsreinigungsgeräts korrespondierenden Ladeanschluss. Die Basisstation zeichnet sich dadurch aus, dass die Basisstation mindestens ein weiteres Lademodul mit einem weiteren zu einem weiteren Ladeanschluss eines Zubehörs korrespondierenden Ladeanschluss umfasst.Another aspect of the invention is a base station for a household cleaning appliance, in particular for a household cleaning appliance described above, comprising a first charging module with a first charging connection corresponding to a further charging connection of a base body of a household cleaning appliance. The base station is characterized in that the base station comprises at least one further charging module with a further charging connection corresponding to a further charging connection of an accessory.

Indem ein Zubehör umfassend einen weiteren wiederaufladbaren Energiespeicher z.B. in Form eines Akkumulators an eine Basisstation elektrisch angeschlossen werden kann, kann das Zubehör unabhängig von dem Grundkörper bzw. dem Hauptaggregat eines Haushaltsreinigungsgeräts geladen werden. Vorzugsweise kann die Basisstation ein Lademodul für den Grundkörper und mindestens ein Lademodul für mindestens ein Zubehör aufweisen. Die zumindest zwei Lademodule können jeweils derart eingerichtet sein, dass sie möglichst optimal zu den Ladeerfordernissen des jeweiligen Energiespeichers korrespondieren. So kann ein erstes Lademodul einen ersten Ladestrom für einen ersten wiederaufladbaren Energiespeicher eines Grundkörpers und ein weiteres Lademodul einen (evtl.) anderen Ladestrom (z.B. mit einer anderen Stromstärke) für einen weiteren wiederaufladbaren Energiespeicher eines Zubehörs bereitstellen.Since an accessory comprising a further rechargeable energy storage device, e.g. in the form of an accumulator, can be electrically connected to a base station, the accessory can be charged independently of the main body or the main unit of a household cleaning appliance. The base station can preferably have a charging module for the base body and at least one charging module for at least one accessory. The at least two charging modules can each be set up in such a way that they correspond as optimally as possible to the charging requirements of the respective energy store. A first charging module can provide a first charging current for a first rechargeable energy store of a base body and a further charging module can provide a (possibly) different charging current (e.g. with a different current strength) for a further rechargeable energy store of an accessory.

Während der wiederaufladbare Energiespeicher des Zubehörs geladen wird, kann ein Benutzer den Grundkörper mit einem weiteren Zubehör und dessen wiederaufladbaren Energiespeicher betreiben oder den ersten wiederaufladbaren Energiespeicher des Grundkörpers laden. Beispielsweise kann die Basisstation mit den zumindest zwei Lademodulen in Form einer Aufbewahrungsbox für den Grundkörper und insbesondere für eine Mehrzahl von Zubehören gebildet sein. Vorzugsweise können eine Mehrzahl von Zubehören, insbesondere deren jeweiliger Ladeanschluss, nach einem Anordnen eines Zubehörs in einer entsprechenden Aufnahme der Basisstation direkt die Ladeanschlusskontakte der Basisstation bzw. des Lademoduls der Basisstation kontaktieren. So kann erreicht werden, dass die Zubehöre in einfacher Weise geladen werden können. Hierdurch kann die Betriebsdauer eines Haushaltsreinigungsgeräts erhöht werden. Insbesondere kann mittels der Basisladestation eine Art von Wechselakkukonzept bereitgestellt werden. Der Unterschied zu bekannten Wechselakkukonzepten besteht darin, dass vorliegend die Zubehöre ausgetauscht werden und nicht die Energiespeicher selber. Dies erhöht den Bedienungskomfort noch weiter.While the rechargeable energy store of the accessory is being charged, a user can use the base body with a further accessory and its Operate rechargeable energy store or charge the first rechargeable energy store of the base body. For example, the base station with the at least two charging modules can be in the form of a storage box for the base body and in particular for a plurality of accessories. A plurality of accessories, in particular their respective charging connection, can preferably contact the charging connection contacts of the base station or of the charging module of the base station directly after an accessory has been arranged in a corresponding receptacle of the base station. In this way it can be achieved that the accessories can be loaded in a simple manner. This allows the service life of a household cleaning appliance to be increased. In particular, a type of exchangeable battery concept can be provided by means of the base charging station. The difference to known interchangeable battery concepts is that in the present case the accessories are exchanged and not the energy storage device itself. This further increases the ease of use.

Es gibt nun eine Vielzahl von Möglichkeiten, das erfindungsgemäße Haushaltsreinigungsgerät und die erfindungsgemäße Basisstation auszugestalten und weiterzuentwickeln. Hierzu sei einerseits verwiesen auf die den unabhängigen Patentansprüchen nachgeordneten Patentansprüche, andererseits auf die Beschreibung von Ausführungsbeispielen in Verbindung mit der Zeichnung.

There are now a large number of possibilities for designing and further developing the household cleaning device according to the invention and the base station according to the invention. For this purpose, reference is made, on the one hand, to the claims subordinate to the independent claims, and, on the other hand, to the description of exemplary embodiments in conjunction with the drawing. In the drawing shows:

Fig. 3
a schematic view of an embodiment of a base station according to the present invention.

Nachfolgend werden für gleiche Elemente gleiche Bezugszeichen verwendet.The same reference symbols are used below for the same elements.

Die Figur 1 zeigt eine schematische Ansicht eines Ausführungsbeispiels eines Haushaltsreinigungsgeräts 2 in Form eines Handstaubsaugers 2. Der Handstaubsauger 2 ist zur Reinigung einer Oberfläche 24, z.B. ein Boden 24, eingerichtet. Der Handstaubsauger 2 umfasst einen Grundkörper 14 und ein mit dem Grundkörper 14 verbundenes Zubehör 4.the Figure 1 shows a schematic view of an exemplary embodiment of a household cleaning device 2 in the form of a hand-held vacuum cleaner 2. The hand-held vacuum cleaner 2 is set up for cleaning a surface 24, for example a floor 24. The hand-held vacuum cleaner 2 comprises a base body 14 and an accessory 4 connected to the base body 14.

Der Grundkörper 14 umfasst eine Saugvorrichtung 26 mit einem innenliegenden Arbeitselement 8 in Form eines Sauggebläses 8. Das Sauggebläse 8 wird von einem Elektromotor 6 angetrieben. Ferner umfasst die Saugvorrichtung 26 eine Aufnahme 28 für einen Staubbeutel (nicht dargestellt).The base body 14 comprises a suction device 26 with an internal working element 8 in the form of a suction fan 8. The suction fan 8 is driven by an electric motor 6. Furthermore, the suction device 26 comprises a receptacle 28 for a dust bag (not shown).

Darüber hinaus ist im vorliegenden Ausführungsbeispiel der Grundkörper 14 über eine Stange 18 mit einem Handgriff 20 verbunden, so dass ein Benutzer im Stehen den Handstaubsauger 2 betreiben kann. Die Stange 18 ist insbesondere eine Teleskopstange 18. Über einen Hauptschalter 30 kann ein Benutzer den Staubsauger 2 aktivieren. Bei Aktivierung wird insbesondere der Elektromotor 6 mit elektrischer Spannung beaufschlagt, um das Gebläse 8 anzutreiben. Die elektrische Energieversorgung erfolgt vorliegend über einen ersten in dem Grundkörper 14 des Staubsaugers 2 installierten wiederaufladbaren Energiespeicher 12.Furthermore, in the present exemplary embodiment, the base body 14 is connected to a handle 20 via a rod 18, so that a user can operate the hand-held vacuum cleaner 2 while standing. The rod 18 is in particular a telescopic rod 18. A user can activate the vacuum cleaner 2 via a main switch 30. When activated, in particular the electric motor 6 is subjected to electrical voltage in order to drive the fan 8. In the present case, the electrical energy supply takes place via a first rechargeable energy store 12 installed in the base body 14 of the vacuum cleaner 2.

Vorliegend weist der Staubsauger 2 eine elektrische Energieversorgung in Form eines in dem Zubehör 4 installierten weiteren wiederaufladbaren Energiespeichers 10 auf. Vorzugsweise sind als wiederaufladbare Energiespeicher 10, 12 Akkumulatoren 10, 12 vorgesehen. Über eine elektrische Verbindung 16 in Form einer Leitung 16 wird der elektrische Antrieb 6 von den Akkumulatoren 10, 12 mit elektrischer Energie versorgt.In the present case, the vacuum cleaner 2 has an electrical energy supply in the form of a further rechargeable energy store 10 installed in the accessory 4. Accumulators 10, 12 are preferably provided as rechargeable energy stores 10, 12. Via an electrical connection 16 in the form of a line 16, the electrical drive 6 is supplied with electrical energy from the accumulators 10, 12.

Das Zubehör 4 ist im vorliegenden Beispiel in Form eines passiven Zubehörs 4 ausgebildet. Ein passives Zubehör 4 umfasst keine elektrisch betriebenen Verbraucher. Das dargestellte Zubehör umfasst ein passives Arbeitselement 22 in Form eines Borstenstreifens 22.In the present example, the accessory 4 is designed in the form of a passive accessory 4. A passive accessory 4 does not include any electrically operated accessories Consumer. The accessory shown comprises a passive working element 22 in the form of a bristle strip 22.

Indem ein zusätzlicher Energiespeicher 10 in dem Zubehör 4 implementiert ist, kann die maximal zur Verfügung stehende Leistung und/oder die Betriebsdauer des Staubsaugers 2 erhöht werden, ohne dass der Staubsauger 2 von einem Benutzer als zu schwer in der Hand liegend wahrgenommen wird. Grund hierfür ist, dass das Gewicht des zusätzlichen wiederaufladbaren Energiespeichers 10 vorliegend (überwiegend) auf den Laufrollen 32 und des Borstenstreifens 22 des Zubehörs 4 verteilt ist.By implementing an additional energy store 10 in the accessory 4, the maximum available power and / or the operating time of the vacuum cleaner 2 can be increased without the vacuum cleaner 2 being perceived by a user as lying too heavy in the hand. The reason for this is that the weight of the additional rechargeable energy store 10 in the present case is (predominantly) distributed on the rollers 32 and the bristle strip 22 of the accessory 4.

Eine erhöhte Gesamtspeicherkapazität der Energiespeicher 10, 12 wird durch eine Parallelschaltung der wiederaufladbaren Energiespeicher 10, 12 und eine Erhöhung der zur Verfügung stehenden maximalen Leistung durch eine Reihenschaltung der wiederaufladbaren Energiespeicher 10, 12 erzielt.An increased total storage capacity of the energy stores 10, 12 is achieved by connecting the rechargeable energy stores 10, 12 in parallel and increasing the available maximum power by connecting the rechargeable energy stores 10, 12 in series.

Hierzu ist im vorliegenden Ausführungsbeispiel eine erste Schaltereinheit 13 zwischen dem weiteren wiederlaufladbaren Energiespeicher 10 des Zubehörs 4 und dem ersten wiederlaufladbaren Energiespeicher 12 des Grundkörpers 14 angeordnet. Die erste Schaltereinheit 13 ist eingerichtet, in einer ersten Schaltstellung die wiederaufladbaren Energiespeicher 10, 12 parallel zu verschalten und in einer zweiten Schaltstellung die wiederaufladbaren Energiespeicher 10, 12 in Reihe zu verschalten. Die steuerbare erste Schaltereinheit 13 wird von einer Steuereinheit 11 angesteuert. Die Steuereinheit 11 kann eingerichtet sein, die erste Schaltereinheit 13 abhängig von einem augenblicklichen Betriebszustand des Staubsaugers 2 und/oder einem augenblicklichen Betriebsmodus des Staubsaugers 2 und/oder der Zubehörart des mit dem Grundkörper 14 verbundenen Zubehörs 4 zu steuern.For this purpose, in the present exemplary embodiment, a first switch unit 13 is arranged between the further rechargeable energy store 10 of the accessory 4 and the first rechargeable energy store 12 of the base body 14. The first switch unit 13 is set up to connect the rechargeable energy stores 10, 12 in parallel in a first switch position and to connect the rechargeable energy stores 10, 12 in series in a second switch position. The controllable first switch unit 13 is activated by a control unit 11. The control unit 11 can be set up to control the first switch unit 13 as a function of an instantaneous operating state of the vacuum cleaner 2 and / or an instantaneous operating mode of the vacuum cleaner 2 and / or the type of accessory of the accessory 4 connected to the base body 14.

Beispielsweise kann ein Benutzer einen ersten Betriebsmodus vorgeben, bei dem eine (gegenüber einem Normalmodus oder Energiesparmodus) erhöhte maximal verfügbare Leistung bereitgestellt wird. Hierdurch kann in dem ersten Betriebsmodus beispielsweise die maximale Saugleistung erhöht werden. Detektiert die Steuereinheit 11 den ersten Betriebsmodus, so bewirkt sie durch Ansteuerung der ersten Schaltereinheit 13 eine Reihenschaltung der wiederaufladbaren Energiespeicher 10, 12. Wird hingegen ein zweiter Betriebsmodus, wie ein Energiesparmodus, vorgegeben und detektiert, kann die Steuereinheit 11 eine Parallelschaltung der wiederaufladbaren Energiespeicher 10, 12 durch die erste Schaltereinheit 13 bewirken.For example, a user can specify a first operating mode in which an increased maximum available power is provided (compared to a normal mode or energy-saving mode). This allows in the first operating mode for example, the maximum suction power can be increased. If the control unit 11 detects the first operating mode, it effects a series connection of the rechargeable energy stores 10, 12 by activating the first switch unit 13 , 12 through the first switch unit 13.

Auch kann vorgesehen sein, dass ein Betriebsmodus automatisch eingestellt wird. Mindestens ein (nicht gezeigter) Sensor, wie ein Ultraschall-Sensor, kann die augenblicklich zu reinigende Oberflächenart detektieren. Ein (nicht gezeigtes) Auswertemodul kann abhängig von gespeicherten Vorgaben aus der detektierten Bodenart den Betriebsmodus ableiten und den Staubsauger 2 entsprechend konfigurieren. Dies kann vorliegend eine Änderung der Verschaltung der zumindest zwei wiederaufladbaren Energiespeicher 10, 12 umfassen.It can also be provided that an operating mode is set automatically. At least one sensor (not shown), such as an ultrasonic sensor, can detect the type of surface to be cleaned at the moment. An evaluation module (not shown) can, depending on stored specifications, derive the operating mode from the detected soil type and configure the vacuum cleaner 2 accordingly. In the present case, this can include a change in the interconnection of the at least two rechargeable energy stores 10, 12.

In einer bevorzugten Ausführungsform kann die erste Schaltereinheit 13 zusätzlich eingerichtet sein, in einer dritten Schaltstellung den elektrischen Verbraucher 6 des Grundkörpers 14 ausschließlich mit Energie aus dem weiteren wiederaufladbaren Energiespeicher 10 des Zubehörs 4 zu versorgen. Auch dies kann von der Steuereinheit 11 abhängig von einem augenblicklichen Betriebszustand des Staubsaugers 2 und/oder einem augenblicklichen Betriebsmodus des Staubsaugers 2 und/oder der Zubehörart des mit dem Grundkörper 14 verbundenen Zubehörs 4 gesteuert werden.In a preferred embodiment, the first switch unit 13 can additionally be set up to supply the electrical consumer 6 of the base body 14 exclusively with energy from the further rechargeable energy store 10 of the accessory 4 in a third switch position. This can also be controlled by the control unit 11 depending on an instantaneous operating state of the vacuum cleaner 2 and / or an instantaneous operating mode of the vacuum cleaner 2 and / or the type of accessory of the accessory 4 connected to the base body 14.

Das Zubehör 4 ist vorliegend abnehmbar mit einem Endteil des Grundkörpers 14 verbunden. Um eine elektrische Verbindung zwischen dem Energiespeicher 10 des Zubehörs 4 und z.B. dem Elektromotor 6 des Grundkörpers 14 herzustellen, ist eine Steckverbindung 36 vorgesehen. Die Steckverbindung 36 ist in einer Ausschnittsvergrößerung in Figur 1 zu erkennen. Insbesondere weist das Zubehör 4 ein zu dem Steckerelement 36.2 des Grundkörpers 14 korrespondierendes Steckerelement 36.1 auf.In the present case, the accessory 4 is detachably connected to an end part of the base body 14. In order to establish an electrical connection between the energy store 10 of the accessory 4 and, for example, the electric motor 6 of the base body 14, a plug connection 36 is provided. The connector 36 is shown in an enlarged detail Figure 1 to recognize. In particular, the accessory 4 a plug element 36.1 corresponding to the plug element 36.2 of the base body 14.

Vorliegend ist das abnehmbare Zubehör 4 ferner mit einem Ladeanschluss 34 ausgestattet, der lediglich beispielhaft an einer Seitenwand des Zubehörs 4 angeordnet ist. Der Ladeanschluss 34 verfügt insbesondere über geeignete elektrische Kontakte. Über den Ladeanschluss 34 kann der weitere wiederaufladbare Energiespeicher 10 mittels eines ankoppelbaren Ladegeräts (nicht gezeigt) wiederaufgeladen werden. Beispielsweise kann bei Detektion eines entladenen wiederaufladbaren Energiespeichers 10 eines Zubehörs 4 dieses Zubehör 4 von dem Grundkörper 14 abgenommen und durch ein Zubehör 4 mit einem geladenen Energiespeicher 10 ersetzt werden. Ein Wechselakkumulatorkonzept kann zur Verfügung gestellt werden.In the present case, the removable accessory 4 is also equipped with a charging connection 34, which is arranged on a side wall of the accessory 4, merely as an example. In particular, the charging connection 34 has suitable electrical contacts. The further rechargeable energy store 10 can be recharged via the charging connection 34 by means of a charger (not shown) that can be connected. For example, when a discharged, rechargeable energy store 10 of an accessory 4 is detected, this accessory 4 can be removed from the base body 14 and replaced by an accessory 4 with a charged energy store 10. An exchangeable accumulator concept can be provided.

Ein weiteres schematisch dargestelltes Ausführungsbeispiel eines Haushaltsreinigungsgeräts 2.1 gemäß der vorliegenden Erfindung ist in der Figur 2 dargestellt. Das vorliegend dargestellte Haushaltsreinigungsgerät 2.1 in Form eines Handstaubsaugers 2.1 umfasst ein aktives Zubehör 4.1. Das dargestellte Zubehör 4.1 ist eine Saugpolierdüse 4.1 mit einer als Arbeitselement 40 ausgebildeten Wischereinheit 40. Die Wischereinheit 40 umfasst einen Schwingkörper 42 und einen Wischtuchträger 44. Ein elektrischer Verbraucher in Form eines Elektromotors 46 ist zum Antreiben der Wischereinheit 40 vorgesehen. Der Elektromotor 46 kann eine schwingende oder rotierende Bewegung des Wischtuchträgers 44 erzeugen. Der Doppelpfeil 48 deutet beispielhaft eine lineare Bewegung des Schwingkörpers 42 an, mit der der Wischtuchträger 44 über den Boden 24 bewegt wird. Während dieser Bewegung erfolgt ein feuchtes oder trockenes Reinigen oder Polieren des Untergrunds 24. Zusätzlich können seitlich neben dem Schwingkörper 42 Saugkanäle 50 angeordnet sein, um Partikel aufzusaugen. Ein Wischtuch wird dabei mittels Klettverschlüssen am Wischtuchträger 44 abnehmbar befestigt.Another schematically illustrated embodiment of a household cleaning appliance 2.1 according to the present invention is shown in FIG Figure 2 shown. The household cleaning device 2.1 shown here in the form of a hand-held vacuum cleaner 2.1 includes an active accessory 4.1. The accessory 4.1 shown is a suction polishing nozzle 4.1 with a wiper unit 40 designed as a working element 40. The wiper unit 40 comprises an oscillating body 42 and a wiper support 44. An electrical consumer in the form of an electric motor 46 is provided for driving the wiper unit 40. The electric motor 46 can generate an oscillating or rotating movement of the wiper support 44. The double arrow 48 indicates, by way of example, a linear movement of the oscillating body 42 with which the wiper support 44 is moved over the floor 24. During this movement there is a moist or dry cleaning or polishing of the substrate 24. In addition, suction channels 50 can be arranged laterally next to the oscillating body 42 in order to suck up particles. A wipe is detachably attached to the wipe carrier 44 by means of Velcro fasteners.

Zur elektrischen Energieversorgung weisen der Handstaubsauger 2.1 und das Zubehör 4.1 zwei wiederaufladbare Energiespeicher 10, 12 in Form von Akkumulatoren 10, 12 auf.The handheld vacuum cleaner 2.1 and the accessories 4.1 have two rechargeable energy stores 10, 12 in the form of accumulators 10, 12 for the electrical energy supply.

Wie bereits ausgeführt wurde, können die wiederaufladbaren Energiespeicher 10, 12 durch die erste Schaltereinheit 13 zumindest parallel oder in Reihe geschaltet werden.As already stated, the rechargeable energy stores 10, 12 can be connected at least in parallel or in series by the first switch unit 13.

Ferner ist im vorliegenden Ausführungsbeispiel eine erste Erfassungseinheit 15 zum Erfassen des augenblicklichen Ladezustands des ersten wiederaufladbaren Energiespeichers 12 vorgesehen. Der gemessene Ladezustand kann von der Erfassungseinheit 15 der Steuereinheit 11 zur Verfügung gestellt werden.Furthermore, in the present exemplary embodiment, a first detection unit 15 is provided for detecting the current state of charge of the first rechargeable energy store 12. The measured state of charge can be made available to the control unit 11 by the detection unit 15.

Der weitere wiederaufladbare Energiespeicher 10 kann ferner über eine zweite Schaltereinheit 52 mit dem Elektromotor 6 des Grundkörpers 14 und/oder dem Elektromotor 46 des Zubehörs 4.1 elektrisch verbunden werden. Die zweite Schaltereinheit 52 kann insbesondere von der Steuereinheit 11 über eine (nicht gezeigte) Kommunikationsverbindung angesteuert werden. Alternativ oder zusätzlich kann eine weitere (nicht gezeigte) Steuereinheit in dem Zubehör 4.1 zur Steuerung der zweiten Schaltereinheit 52 vorgesehen sein.The further rechargeable energy store 10 can also be electrically connected to the electric motor 6 of the base body 14 and / or the electric motor 46 of the accessory 4.1 via a second switch unit 52. The second switch unit 52 can in particular be activated by the control unit 11 via a communication connection (not shown). Alternatively or additionally, a further control unit (not shown) can be provided in the accessory 4.1 for controlling the second switch unit 52.

Darüber hinaus ist eine weitere Erfassungseinheit 54 zum Erfassen des augenblicklichen Ladezustands des weiteren wiederaufladbaren Energiespeichers 10 in dem Zubehör 4.1 angeordnet. Über eine (nicht gezeigte) Kommunikationsverbindung kann der erfasste Ladezustand der ersten Steuereinheit 11 zur Verfügung gestellt werden.In addition, a further detection unit 54 for detecting the current state of charge of the further rechargeable energy store 10 is arranged in the accessory 4.1. The recorded state of charge can be made available to the first control unit 11 via a communication connection (not shown).

Der Steuereinheit 11 kann abhängig von dem Betriebszustand des Staubsaugers 2.1, insbesondere von den empfangenen augenblicklichen Ladezuständen der zumindest zwei wiederaufladbaren Energiespeicher 10, 12, die erste Schaltereinheit 13 steuern. Beispielsweise kann in der Steuereinheit 11 zumindest ein erster Vergleichsladezustand zumindest für einen wiederaufladbaren Energiespeicher 10, 12 hinterlegt sein. Die Steuereinheit 11 kann eingerichtet sein, beispielsweise den augenblicklichen Ladezustand des ersten Energiespeichers 12 mit dem ersten Vergleichsladezustand (z.B. ein Wert zwischen 10 % und 50 %) zu vergleichen. Unterschreitet der augenblickliche Ladezustand des ersten wiederaufladbaren Energiespeichers 12 den vorgegebenen ersten Vergleichsladezustand, kann die Steuereinheit 11 bewirken, dass insbesondere unabhängig von einem aktuellen Betriebsmodus die wiederaufladbaren Energiespeicher 10, 12 parallel geschaltet werden.The control unit 11 can control the first switch unit 13 as a function of the operating state of the vacuum cleaner 2.1, in particular of the received instantaneous charge states of the at least two rechargeable energy stores 10, 12. For example, at least one first comparison state of charge at least for a rechargeable energy store 10, 12 can be used in the control unit 11 be deposited. The control unit 11 can be set up, for example, to compare the current state of charge of the first energy store 12 with the first comparison state of charge (for example a value between 10% and 50%). If the current state of charge of the first rechargeable energy store 12 falls below the specified first comparison state of charge, the control unit 11 can cause the rechargeable energy stores 10, 12 to be connected in parallel, in particular regardless of a current operating mode.

Über den Kommunikationseingang 17 kann der Steuereinheit 11 zum Beispiel der augenblickliche bzw. der gewünschte Betriebsmodus bereitgestellt werden. Beispielsweise kann der Betriebsmodus durch den Benutzer und/oder durch eine Eingabe über eine (nicht gezeigte) Benutzerschnittstelle und/oder mittels eines oder mehrerer (nicht gezeigte) Sensors/en und/oder durch ein die Art des verwendeten Zubehörs 4.1 repräsentierendes Steuersignal bereitgestellt werden. Das Steuersignal kann beispielsweise von einer in dem Zubehör 4.1 angeordneten (nicht gezeigten) Steuerung generiert und an die Steuereinheit 11 übertragen oder aus einem in dem Zubehör 4.1 angeordneten (nicht gezeigten) Speicher von der Steuereinheit 11 ausgelesen werden.Via the communication input 17, the control unit 11 can, for example, be provided with the current or the desired operating mode. For example, the operating mode can be provided by the user and / or by an input via a user interface (not shown) and / or by means of one or more sensors (not shown) and / or by a control signal representing the type of accessory 4.1 used. The control signal can, for example, be generated by a controller (not shown) arranged in the accessory 4.1 and transmitted to the control unit 11 or read out by the control unit 11 from a memory (not shown) arranged in the accessory 4.1.

Ferner kann vorgesehen sein, dass der Elektromotor 46 ausschließlich von dem in dem Zubehör 4.1 implementierten weiteren Energiespeicher 10 mit elektrischer Energie versorgt wird. Dies gilt unter dem Vorbehalt, dass der weitere Energiespeicher 10 noch eine ausreichende Ladungsmenge aufweist. Der Vorteil einer entsprechenden Verschaltung besteht darin, dass der Strom nicht erst zum Grundkörper 14 geleitet und von dort zurück zum Motor 46 des Zubehörs 4.1 zurückgeleitet werden muss.Furthermore, it can be provided that the electric motor 46 is supplied with electrical energy exclusively by the additional energy store 10 implemented in the accessory 4.1. This applies with the proviso that the further energy store 10 still has a sufficient amount of charge. The advantage of a corresponding interconnection is that the current does not first have to be passed to the base body 14 and from there back to the motor 46 of the accessory 4.1.

Darüber hinaus offenbart die Figur 3 ein Ausführungsbeispiel einer Basisstation 60 gemäß der vorliegenden Erfindung. Die Basisstation 60 ist insbesondere eine Ladestation 60 für vorliegend ein Haushaltsreinigungsgerät 2, 2.1 und zwei Zubehöre 4, 4.1 (Gerät und Zubehöre nicht dargestellt). Über ein Kabel 74 kann die Basisstation 60 mit einem elektrischen Versorgungsnetz (nicht gezeigt) elektrisch verbunden werden.In addition, the Figure 3 an embodiment of a base station 60 according to the present invention.
