Description
Die Erfindung betrifft einen Bodenstaubsauger.The invention relates to a vacuum cleaner.
Staubsauger gibt es in einer Vielzahl verschiedener Konfigurationen bzw. Bauarten. Zu den bekanntesten Bauarten gehören der Upright-Staubsauger, der Handstaubsauger und der Bodenstaubsauger.Vacuum cleaners come in a variety of different configurations. The best-known types include the Upright vacuum cleaner, the hand vacuum cleaner and the vacuum cleaner.
Ein Upright-Staubsauger umfasst eine verfahrbare Bodeneinheit, über der ein Oberkörper mit einem Staubsaugerbehälter angeordnet ist, wobei die beiden Teile schwenkbar zueinander gelagert sind. In der Bodeneinheit ist typischerweise eine elektrisch angetriebene Bürste vorgesehen. Ein Upright-Staubsauger ist beispielsweise in der
Der Handstaubsauger umfasst ein Gehäuse mit einem motorgetriebenen Gebläse und einem Staubsammelraum. Auf der einen Seite führt ein Saugrohr aus dem Gehäuse, an dessen Ende sich eine Bodendüse befindet. Auf der anderen Seite des Gehäuses ist ein Handgriff, gegebenenfalls an einem Stab angeordnet.The hand vacuum cleaner comprises a housing with a motor-driven blower and a dust collection room. On the one hand, a suction pipe leads out of the housing, at the end of which there is a floor nozzle. On the other side of the housing is a handle, optionally arranged on a rod.
Bodenstaubsauger umfassen ein Gehäuse, das auf Rollen und/oder Gleitkufen gelagert ist. In dem Gehäuse ist ein Staubsammelbehälter angeordnet, in dem sich ein Filterbeutel befindet. Eine Bodendüse ist über ein Saugrohr und einen Saugschlauch mit dem Staubsammelraum verbunden. Bei den herkömmlichen Bodenstaubsaugern ist im Gehäuse weiterhin eine Motorgebläseeinheit angeordnet, die im Staubsammelbehälter einen Unterdruck erzeugt. In Luftströmungsrichtung ist somit die Motorgebläseeinheit hinter der Bodendüse, dem Saugrohr, dem Saugschlauch sowie dem Staubsammelbehälter bzw. dem Filterbeutel angeordnet. Da derartige Motorgebläseeinheiten von gereinigter Luft durchströmt werden, werden sie manchmal auch als Reinluft-Motoren ("Clean-Air-Motor") bezeichnet.Underground vacuum cleaners comprise a housing which is mounted on rollers and / or skids. In the housing, a dust collector is arranged, in which a filter bag is located. A floor nozzle is connected to the dust collecting space via a suction pipe and a suction hose. In the conventional vacuum cleaner in the housing further an engine fan unit is arranged, which generates a negative pressure in the dust collector. In the air flow direction, the motor fan unit is thus arranged behind the floor nozzle, the suction pipe, the suction hose and the dust collecting container or the filter bag. Since such engine fan units are traversed by purified air, they are sometimes referred to as clean air engines ("clean air engine").
Insbesondere in früheren Zeiten gab es auch Staubsauger, in denen die angesaugte Schmutzluft direkt durch das Motorgebläse hindurch und in einen unmittelbar daran anschließenden Staubbeutel geführt wurde. Beispiele hierfür sind in
Derartige Dreckluft- oder Schmutzluft-Motorgebläse werden auch als "Dirty-Air-Motor" oder "Direct-Air-Motor" bezeichnet. Die Verwendung derartiger Dirty-Air-Motoren wird auch in den Dokumenten
Vor diesem Hintergrund besteht die der Erfindung zugrundeliegende Aufgabe darin, einen verbesserten Bodenstaubsauger bereitzustellen.Against this background, the object underlying the invention is to provide an improved vacuum cleaner.
Diese Aufgabe wird durch den Gegenstand von Anspruch 1 gelöst. Erfindungsgemäß wird ein Bodenstaubsauger bereitgestellt, umfassend eine auf Rollen und/oder Gleitkufen gelagerte Staubsammeleinheit, einen Saugschlauch, ein Saugrohr und eine Bodendüse, wobei die Bodendüste über das Saugrohr und den Saugschlauch mit der Staubsammeleinheit fluidisch verbunden ist, weiterhin umfassend eine Motorgebläseeinheit zum Ansaugen eines Luftstroms durch die Bodendüse, wobei die Motorgebläseeinheit zwischen der Bodendüse und dem Saugrohr derart angeordnet ist, dass ein durch die Bodendüse angesaugter Luftstrom durch die Motorgebläseeinheit hindurch in das Saugrohr strömt.This object is solved by the subject matter of claim 1. According to the invention, there is provided a canister vacuum cleaner comprising a dust collecting unit mounted on rollers and / or skids, a suction hose, a suction pipe and a floor nozzle, wherein the floor deck is fluidly connected to the dust collecting unit via the suction pipe and the suction hose, further comprising an engine blower unit for sucking an air flow through the floor nozzle, wherein the motor blower unit is disposed between the floor nozzle and the suction pipe such that an air flow sucked through the floor nozzle flows through the engine blower unit into the suction pipe.
Damit wird ein Dirty-Air-Motor bzw. Direct-Air-Motor in vorteilhafter Weise in einem Bodenstaubsauger eingesetzt. Auch bei geringer Motorleistung lässt sich mit dem erfindungsgemäßen Bodenstaubsauger ein hoher Volumenstrom erzielen. Ein Dirty-Air-Motor weist beispielsweise eine maximale Drehzahl von weniger als 30.000 U/min und eine elektrische Aufnahmeleisung von weniger als 900 W auf.Thus, a dirty-air engine or direct-air engine is advantageously used in a vacuum cleaner. Even with low engine power, a high volume flow can be achieved with the vacuum cleaner according to the invention. For example, a dirty air engine has a maximum speed of less than 30,000 RPM and an electrical pickup power of less than 900W.
In Luftströmungsrichtung ist die Bodendüse, manchmal auch als "Saugdüse" bezeichnet, vor dem Saugrohr, das Saugrohr vor dem Saugschlauch und der Saugschlauch vor der Staubsammeleinheit angeordnet. Die mittels der Motorgebläseeinheit durch die Bodendüse angesaugte Luft wird zunächst in das Saugrohr, gefolgt vom Saugschlauch und anschließend in die Staubsammeleinheit geführt. Aufgrund der fluidischen bzw. strömungstechnischen Verbindung wird ein durchgängiger Luftstrom durch die Bodendüse, das Saugrohr, den Saugschlauch in die Staubsammeleinheit gewährleistet.In the air flow direction, the floor nozzle, sometimes referred to as a "suction nozzle", is arranged in front of the suction pipe, the suction pipe in front of the suction hose and the suction hose in front of the dust collecting unit. The air sucked in through the floor nozzle by means of the motor fan unit is first led into the suction pipe, followed by the suction hose and then into the dust collecting unit. Due to the fluidic or fluidic connection, a continuous flow of air through the floor nozzle, the suction pipe, the suction hose is ensured in the dust collection unit.
Es hat sich überraschenderweise herausgestellt, dass Schmutzluftmotoren (Dirty-Air-Motoren) auch in Bodenstaubsaugern in vorteilhafter Weise eingesetzt werden können, insbesondere um die durch die Bodendüse angesaugte Schmutzluft in das Saugrohr zu fördern.It has surprisingly been found that dirty air engines (dirty air engines) can also be used in vacuum cleaners in an advantageous manner, in particular to promote the suctioned through the floor nozzle dirty air into the intake manifold.
Anders als bei herkömmlichen Bodenstaubsaugern, wo im Betrieb im Saugrohr, dem Saugschlauch und der Staubsammeleinheit bzw. der Staubsammelkammer ein Unterdruck herrscht, liegt beim erfindungsgemäßen Bodenstaubsauger im Saugrohr, Saugschlauch und in der Staubsammeleinheit ein Überdruck vor. Auf diese Weise können die Wandstärken dieser Teile reduziert bzw. Verstärkungselemente (wie beispielsweise Verstärkungsrippen) in geringerem Umfang eingesetzt oder gar ganz vermieden werden.Unlike conventional vacuum cleaners, where there is a negative pressure during operation in the intake manifold, the suction hose and the dust collection unit or the dust collection chamber, there is an overpressure in the vacuum cleaner according to the invention in the intake manifold, suction hose and in the dust collection unit. In this way, the wall thicknesses of these parts can be reduced or reinforcing elements (such as reinforcing ribs) used to a lesser extent or even completely avoided.
Die Motorgebläseeinheit kann derart ausgebildet sein, dass sie bei einer elektrischen Aufnahmeleistung von weniger als 900 W gemäß DIN EN 60312-1 bei Blende 8 einen Volumenstrom von mehr als 30 l/s, insbesondere von mehr als 40 l/s und insbesondere von mehr als 50 l/s erzeugt. Alternativ oder zusätzlich kann die Motorgebläseeinheit derart ausgebildet sein, dass sie bei einer elektrischen Aufnahmeleistung von weniger als 600 W gemäß DIN EN 60312-1 bei Blende 8 einen Volumenstrom von mehr als 25 l/s, insbesondere von mehr als 30 l/s und insbesondere von mehr als 40 l/s erzeugt. Alternativ oder zusätzlich kann die Motorgebläseeinheit derart ausgebildet sein, dass sie bei einer elektrischen Aufnahmeleistung von weniger als 300 W gemäß DIN EN 60312-1 bei Blende 8 einen Volumenstrom von mehr als 15 l/s, insbesondere von mehr als 25 l/s und insbesondere von mehr als 30 l/s erzeugt.The motor blower unit may be designed such that, with an electrical input power of less than 900 W according to DIN EN 60312-1 at aperture 8, a volume flow of more than 30 l / s, in particular more than 40 l / s and in particular more than 50 l / s generated. Alternatively or additionally, the motor blower unit may be designed such that it has a flow rate of more than 25 l / s, in particular more than 30 l / s and in particular at an electrical power of less than 600 W according to DIN EN 60312-1 at aperture 8 generated by more than 40 l / s. Alternatively or additionally, the motor blower unit may be designed such that, with an electrical power input of less than 300 W according to DIN EN 60312-1 at aperture 8, a volume flow of more than 15 l / s, in particular more than 25 l / s and in particular generated by more than 30 l / s.
Auf diese Weise wird ein besonders effizienter Bodenstaubsauger erhalten.In this way, a particularly efficient vacuum cleaner is obtained.
Die Luftdaten eines Staubsaugers bzw. einer Motorgebläseeinheit werden gemäß DIN EN 60312-1:2014-01 bestimmt. Insbesondere wird auf Abschnitt 5.8 verwiesen. Dabei wird die Messeinrichtung in der Ausführung B gemäß Abschnitt 7.3.7.3 verwendet. Falls eine Motorgebläseeinheit ohne Staubsaugergehäuse gemessen wird, wird ebenfalls die Messeinrichtung B verwendet. Für gegebenenfalls notwendige Zwischenstücke zum Anschluss an die Messkammer gelten die Ausführungen in Abschnitt 7.3.7.1.The air data of a vacuum cleaner or a motor blower unit are determined in accordance with DIN EN 60312-1: 2014-01. In particular, reference is made to section 5.8. The measuring device is used in version B according to section 7.3.7.3. If an engine blower unit without a vacuum cleaner housing is measured, the measuring device B is also used. For any necessary intermediate pieces for connection to the measuring chamber, the instructions in Section 7.3.7.1 apply.
Für den Begriff "Luftstrom" gemäß DIN EN 60312-1 werden auch die Begriffe "Volumenstrom" und "Saugluftstrom" verwendet.The terms "volume flow" and "suction air flow" are also used for the term "air flow" according to DIN EN 60312-1.
Die Bodendüse kann eine Bodenplatte mit einer Grundfläche aufweisen, die im Betrieb des Bodenstaubsaugers der zu saugenden Fläche zugewandt ist, wobei die Bodenplatte parallel zur Grundfläche wenigstens einen Luftströmungskanal mit einer seitlich in der Bodenplatte vorgesehenen Öffnung aufweist. Insbesondere kann die Bodenplatte mit ihrer Grundfläche im Betrieb des Bodenstaubsaugers auf der zu saugenden Fläche aufliegen oder, beispielsweise mittels einer Borstenleiste, von dieser beabstandet sein.The floor nozzle may have a bottom plate with a base surface, which faces the surface to be sucked during operation of the vacuum cleaner, wherein the bottom plate has at least one air flow channel parallel to the base surface with an opening provided laterally in the bottom plate. In particular, the bottom plate can rest with its base in the operation of the vacuum cleaner on the surface to be sucked or, for example by means of a bristle strip, be spaced from this.
Die Bodenplatte wird auch als Düsensohle bezeichnet. Die Bodendüse weist eine Saugöffnung zur Herstellung einer fluidischen Verbindung mit der Motorgebläseeinheit auf. Diese Saugöffnung steht in fluidischer, d.h. strömungstechnischer, Verbindung mit dem wenigstens einen Luftströmungskanal. Durch den wenigstens einen, insbesondere einen oder mehrere Luftströmungskanäle wird der Anpressdruck der Bodendüse bei guter Saugleistung in vorteilhafter Weise eingestellt. Die seitlich in der Bodenplatte vorgesehenen Öffnungen sind quer zur bestimmungsgemäßen Verschieberichtung der Bodendüse vorgesehen. Ein oder mehrere Luftströmungskanäle können von einer Seite der Bodenplatte zur gegenüberliegenden Seite der Bodenplatte (jeweils quer zur Verschieberichtung) vorgesehen sein. Bei derart durchgängigen Luftströmungskanälen ist pro Kanal auf beiden (gegenüberliegenden) Seiten der Bodenplatte jeweils eine Öffnung vorgesehen.The bottom plate is also referred to as a nozzle sole. The floor nozzle has a suction opening for establishing a fluidic connection with the engine fan unit. This suction opening is in fluidic, ie fluidic connection to the at least one air flow channel. By the at least one, in particular one or more air flow channels, the contact pressure of the floor nozzle is set with good suction power in an advantageous manner. The openings provided laterally in the bottom plate are provided transversely to the intended direction of displacement of the floor nozzle. One or more air flow channels may be from one side of the bottom plate to the opposite side of the Base plate (each transverse to the direction of displacement) may be provided. With such continuous air flow channels, an opening is provided per channel on both (opposite) sides of the bottom plate.
Das Saugrohr kann einen Durchmesser in einem Bereich von 25 mm bis 50 mm, insbesondere von 30 mm bis 45 mm und insbesondere von 35 mm bis 45 mm, und/oder eine Länge in einem Bereich von 600 mm bis 1200 mm haben. Das Saugrohr kann starr ausgebildet sein, insbesondere so dass es beim bestimmungsgemäßen Gebrauch durch einen Nutzer nicht deformierbar ist. Das Saugrohr kann teilweise oder vollständig aus Kunststoff oder Metall bestehen.The suction pipe may have a diameter in a range from 25 mm to 50 mm, in particular from 30 mm to 45 mm and in particular from 35 mm to 45 mm, and / or a length in a range from 600 mm to 1200 mm. The suction tube may be rigid, in particular so that it is not deformable when used by a user as intended. The suction tube may be partially or completely made of plastic or metal.
Der Saugschlauch kann einen Durchmesser in einem Bereich von 25 mm bis 50 mm, insbesondere von 30 mm bis 45 mm und insbesondere von 35 mm bis 45 mm, und/oder eine Länge in einem Bereich von 1000 mm bis 2500 mm haben. Der Saugschlauch kann flexibel ausgebildet sein, insbesondere so dass er beim bestimmungsgemäßen Gebrauch durch einen Benutzer deformierbar ist. Der Saugschlauch kann teilweise oder vollständig aus Kunststoff bestehen. Er kann insbesondere eine Kunststoffwand und/oder eine Verstärkung aus Metall (beispielsweise einen Spiraldraht) umfassen.The suction hose may have a diameter in a range from 25 mm to 50 mm, in particular from 30 mm to 45 mm and in particular from 35 mm to 45 mm, and / or a length in a range from 1000 mm to 2500 mm. The suction hose can be designed to be flexible, in particular so that it is deformable during normal use by a user. The suction hose may be partially or completely made of plastic. In particular, it may comprise a plastic wall and / or a reinforcement made of metal (for example a spiral wire).
Das Saugrohr und/oder der Saugschlauch können über ihre jeweilige Länge einen konstanten oder einen variablen Durchmesser aufweisen. Insbesondere können das Saugrohr und/oder der Saugschlauch eine konische Form aufweisen, wobei sich vorzugsweise der Durchmesser zur Bodendüse hin verringert. Die oben angegebenen Durchmesser beziehen sich insbesondere auf den kleinsten Durchmesser des Saugrohrs bzw. des Saugschlauchs.The suction tube and / or the suction hose can have a constant or a variable diameter over their respective length. In particular, the suction pipe and / or the suction hose may have a conical shape, wherein preferably the diameter is reduced towards the floor nozzle. The diameters indicated above relate in particular to the smallest diameter of the suction tube or the suction hose.
Die Bodendüse kann derart ausgebildet und/oder die Motorgebläseeinheit derart angeordnet sein, dass keine Berührung des Gebläserads mit einer Prüfsonde gemäß IEC/EN 60335 durch die Bodendüse möglich ist. Hier wird auf Abschnitt 8 der Version DIN EN 60335-1: 2012-10 Bezug genommen. Insbesondere soll die Prüfsonde B verwendet werden.The floor nozzle can be designed in such a way and / or the motor blower unit can be arranged such that no contact of the blower wheel with a test probe according to IEC / EN 60335 through the floor nozzle is possible. Here reference is made to section 8 of the version DIN EN 60335-1: 2012-10. In particular, the test probe B should be used.
Dies verringert die Gefahr einer Beschädigung der Motorgebläseeinheit und die Gefahr von Verletzungen beim Anfassen der Bodendüse bei laufendem Motor.This reduces the risk of damage to the engine blower unit and the risk of injury when touching the floor nozzle with the engine running.
Der Bodenstaubsauger kann ein Beutelsauger sein, insbesondere mit einer Filterfläche von wenigstens 800 cm2, insbesondere von wenigstens 1500 cm2 und insbesondere von wenigstens 2500 cm2. Ein Beutelsauger ist ein Staubsauger, bei dem der eingesaugte Staub in einem Staubsaugerfilterbeutel abgeschieden und gesammelt wird. Der Bodenstaubsauger kann insbesondere ein Beutelsauger für Wegwerfbeutel sein.The canister vacuum cleaner can be a bag suction device, in particular with a filter surface of at least 800 cm 2 , in particular of at least 1500 cm 2 and in particular of at least 2500 cm 2 . A bag vacuum is a vacuum cleaner in which the sucked dust is separated and collected in a vacuum cleaner filter bag. The canister vacuum cleaner may in particular be a bag suction device for disposable bags.
Die Filterfläche eines Staubsaugerfilterbeutels bezeichnet die gesamte Fläche des Filtermaterials, das sich zwischen bzw. innerhalb der randseitigen Nähte (beispielsweise Schweiß- oder Klebenähte) befindet. Dabei sind auch möglicherweise vorhandene Seiten- oder Oberflächenfalten zu berücksichtigen. Die Fläche der Beutelfüllöffnung bzw. Eintrittsöffnung (einschließlich einer dieser Öffnung umgebenden Naht) ist nicht Teil der Filterfläche.The filter surface of a vacuum cleaner filter bag refers to the entire area of the filter material that is between or within the peripheral seams (eg, weld or glue seams). Possible side or surface wrinkles should also be considered. The area of the bag filling opening or inlet (including a seam surrounding this opening) is not part of the filter surface.
Der Staubsaugerfilterbeutel kann ein Flachbeutel sein oder eine Klotzbodenform aufweisen. Ein Flachbeutel wird durch zwei Seitenwände aus Filtermaterial gebildet, die entlang ihrer Umfangsränder miteinander verbunden (beispielsweise verschweißt oder verklebt) sind. In einer der beiden Seitenwände kann die Beutelfüllöffnung bzw. Eintrittsöffnung vorgesehen sein. Die Seitenflächen bzw. -wände können jeweils eine rechteckige Grundform aufweisen. Jede Seitenwand kann eine oder mehrere Lagen Vlies und/oder Vliesstoff umfassen.The vacuum cleaner filter bag may be a flat bag or have a block bottom shape. A flat bag is formed by two side walls of filter material joined together (e.g., welded or glued) along their peripheral edges. In one of the two side walls, the bag filling opening or inlet opening can be provided. The side surfaces or walls can each have a rectangular basic shape. Each sidewall may comprise one or more layers of nonwoven and / or nonwoven fabric.
Der Bodenstaubsauger in Form eines Beutelsaugers kann einen Staubsaugerfilterbeutel umfassen, wobei der Staubsaugerfilterbeutel in Form eines Flachbeutels und/oder als Wegwerfbeutel ausgebildet ist.The vacuum cleaner in the form of a bag suction can comprise a vacuum cleaner filter bag, wherein the vacuum cleaner filter bag is formed in the form of a flat bag and / or as a disposable bag.
Die Beutelwand des Staubsaugerfilterbeutels kann eine oder mehrere Lagen eines Vlieses und/oder eine oder mehrere Lagen eines Vliesstoffes umfassen. Sie kann insbesondere ein Laminat aus einer oder mehrerer Lagen Vlies und/oder einer oder mehrerer Lagen Vliesstoff umfassen. Ein derartiges Laminat ist beispielsweise in der
Der Begriff Vliesstoff wird im Sinne der Norm DIN EN ISO 9092:2010 verstanden. Dabei werden insbesondere Film- und Papierstrukturen, insbesondere Filterpapier, nicht als Vliesstoff angesehen. Ein "Vlies" ist eine Struktur aus Fasern und/oder Endlosfilamenten oder Kurzfasergarnen, die durch irgendein Verfahren zu einem Flächengebilde geformt wurden (ausgenommen die Verflechtung von Garnen wie in gewobenem Gewebe, geknüpftem Gewebe, Maschenware, Spitze oder getuftetem Gewebe), allerdings nicht durch irgendein Verfahren verbunden wurden. Durch ein Verbindeverfahren wird aus einem Vlies ein Vliesstoff. Das Vlies oder der Vliesstoff können trockengelegt, nassgelegt oder extrudiert sein.The term nonwoven fabric is understood in the sense of the standard DIN EN ISO 9092: 2010. In particular, film and paper structures, in particular filter paper, are not regarded as nonwoven. A "nonwoven" is a structure of fibers and / or filaments or short fiber yarns that have been formed into a sheet by any process (except interweaving yarns such as woven fabric, knit fabric, knit fabric, lace, or tufted fabric) but not through any method have been linked. By a joining method, a nonwoven fabric becomes a nonwoven fabric. The nonwoven or nonwoven fabric may be drained, wet laid or extruded.
Der Bodenstaubsauger kann einen Ausblasfilter, insbesondere mit einer Filterfläche von wenigstens 800 cm2, umfassen. Der Ausblasfilter kann insbesondere plissiert bzw. gefaltet ausgebildet sein. Damit lässt sich eine große Oberfläche bei kleinerer Grundfläche erzielen. Dabei kann der Ausblasfilter in einer Halterung vorgesehen sein, wie sie beispielsweise in der Europäischen Patentanmeldung Nr.
Alternativ kann der Bodenstaubsauger ein beutelloser Sauger, insbesondere mit einem wie zuvor beschriebenen Ausblasfilter mit einer Filterfläche von wenigstens 800 cm2, sein. Ein beutelloser Sauger ist ein Staubsauger, bei dem der eingesaugte Staub ohne einen Staubsaugerfilterbeutel abgeschieden und gesammelt wird. In diesem Fall kann die Staubsammeleinheit einen Prallabscheider oder einen Fliehkraftabscheider bzw. einen Zyklonabscheider umfassen.Alternatively, the canister vacuum cleaner can be a bagless vacuum cleaner, in particular with an exhaust filter as described above with a filter area of at least 800 cm 2 . A bagless vacuum cleaner is a vacuum cleaner in which the sucked dust is separated and collected without a vacuum cleaner filter bag. In this case, the dust collecting unit may include a baffle separator or a centrifugal separator or a cyclone separator.
Bei den zuvor beschriebenen Bodenstaubsaugern kann die Motorgebläseeinheit auf und/oder über der Bodendüse, insbesondere unmittelbar auf und/oder über der Bodendüse, angeordnet sein. Dies führt zu einer vorteilhaften Saugleistung. Darüber hinaus kann ein kompakter Aufbau der Einheit aus Bodendüse und Motorgebläseeinheit erreicht werden. Beispielsweise kann die Motorgebläseeinheit derart angeordnet sein, dass durch die Bodendüse eingesaugte Luft unmittelbar von der Bodendüse in die Motorgebläseeinheit eintritt.In the case of the above-described vacuum cleaners, the engine blower unit can be arranged on and / or above the floor nozzle, in particular directly on and / or above the floor nozzle. This leads to an advantageous suction performance. In addition, a compact structure of the unit of floor nozzle and motor fan unit can be achieved. For example, the engine blower unit may be arranged such that air taken in by the floor nozzle enters the engine blower unit directly from the floor nozzle.
Die Motorgebläseeinheit kann über ein Rohrstück mit der Bodendüse fluidisch verbunden sein. In diesem Fall ist die Motorgebläseeinheit nicht mehr unmittelbar auf und/oder über der Bodendüse angeordnet. Das Rohrstück kann insbesondere eine Länge von 10 mm bis 1200 mm vorzugsweise von 10 mm bis 300 mm haben.The engine blower unit may be fluidly connected to the floor nozzle via a pipe section. In this case, the engine blower unit is no longer located directly on and / or above the floor nozzle. The pipe section may in particular have a length of 10 mm to 1200 mm, preferably 10 mm to 300 mm.
Die Motorgebläseeinheit kann ein (insbesondere einstufiges) Radialgebläse aufweisen. Bei einem Radialgebläse wird die Luft parallel oder axial zur Antriebsachse des Gebläserads angesaugt und durch die Rotation des Gebläserads umgelenkt, insbesondere um etwa 90° umgelenkt, und radial ausgeblasen.The engine blower unit may have a (in particular single-stage) radial blower. In a radial fan, the air is sucked parallel or axially to the drive axis of the impeller and deflected by the rotation of the impeller, in particular deflected by about 90 °, and blown out radially.
Die zuvor beschriebenen Bodenstaubsauger können eine zweite Motorgebläseeinheit umfassen. Bei der zweiten Motorgebläseeinheit kann es sich um einen Dirty-Air-Motor oder einen Clean-Air-Motor (wie oben beschrieben) handeln.The above-described canister vacuum cleaner may include a second engine blower unit. The second engine blower unit may be a dirty air engine or a clean air engine (as described above).
Insbesondere im Falle eines Dirty-Air-Motors kann die zweite Motorgebläseeinheit beispielsweise zwischen der Bodendüse und dem Saugrohr derart angeordnet sein, dass ein durch die Bodendüse angesaugter Luftstrom durch die zweite Motorgebläseeinheit hindurch in das Saugrohr strömt. Insbesondere kann die zweite Motorgebläseeinheit fluidisch unmittelbar nach der ersten Motorgebläseeinheit angeordnet sein.In particular, in the case of a dirty air engine, the second engine blower unit, for example, be arranged between the floor nozzle and the suction pipe such that a sucked through the floor nozzle air flow through the second motor blower unit into the suction pipe flows. In particular, the second engine blower unit can be arranged fluidly immediately after the first engine blower unit.
Alternativ kann die Motorgebläseeinheit zwischen dem Saugschlauch und der Staubsammeleinheit derart angeordnet sein, dass ein durch den Saugschlauch angesaugter Luftstrom durch die zweite Motorgebläseeinheit hindurch in die Staubsammeleinheit strömt. Die Staubsammeleinheit kann ein Gehäuse umfassen, wobei die zweite Motorgebläseeinheit an dem Gehäuse angeordnet ist.Alternatively, the engine blower unit may be disposed between the suction hose and the dust collection unit such that an air flow sucked through the suction hose flows through the second engine blower unit into the dust collection unit. The dust collection unit may include a housing, wherein the second motor blower unit is disposed on the housing.
Insbesondere im Falle eines Clean-Air-Motors kann die zweite Motorgebläseeinheit fluidisch hinter der Staubsammeleinheit angeordnet sein.In particular, in the case of a clean-air engine, the second engine blower unit may be arranged fluidly behind the dust-collecting unit.
Die erste und die zweite Motorgebläseeinheit können gleiche oder unterschiedliche elektrische Leistungsaufnahmen aufweisen. Die elektrische Aufnahmeleistung jeder Motorgebläseeinheit kann insbesondere zwischen 50 und 400 W liegen. Die Summe der elektrischen Aufnahmeleistung beider Motorgebläseeinheiten kann insbesondere höchstens 900 W betragen.The first and second motor blower units may have the same or different electrical power consumption. The electrical power consumption of each engine fan unit can be between 50 and 400 W in particular. The sum of the electrical power consumption of both engine fan units may be at most 900 W in particular.
Es hat sich herausgestellt, dass die Verwendung einer zweiten, unterstützenden Motorgebläseeinheit das Verstopfungsverhalten eines Staubsaugerfilterbeutels positiv beeinflusst und ein hoher Volumenstrom erreicht werden kann. Dies führt zu einer guten Staubaufnahme der Bodendüse.It has been found that the use of a second, assisting engine fan unit positively influences the clogging behavior of a vacuum cleaner filter bag and a high volume flow can be achieved. This leads to a good dust absorption of the floor nozzle.
Grundsätzlich kann die Bodendüse eine aktive oder eine passive Bodendüse sein. Eine aktive Bodendüse weist in der Saugöffnung eine Bürstenwalze (manchmal auch als Klopf- und/oder Rotationsbürste bezeichnet) auf. Die Bürstenwalze kann elektromotorisch antreibbar sein. Eine passive Bodendüse weist keine Bürstenwalze auf.In principle, the floor nozzle can be an active or a passive floor nozzle. An active floor nozzle has a brush roller (sometimes referred to as a knock and / or rotary brush) in the suction opening. The brush roller can be driven by an electric motor. A passive floor nozzle has no brush roller.
Bei den beschriebenen Bodenstaubsaugern kann aufgrund der Gesamtkonstruktion auch mit einer passiven Bodendüse, also ohne Bürstenwalze, eine sehr gute Effizienz und Saugleistung erzielt werden. Beim Einsatz von passiven Bodendüsen vereinfacht sich der Aufbau und damit auch das Gewicht der Bodendüse, wodurch die Handhabung vereinfacht wird.In the described vacuum cleaners can be achieved due to the overall construction with a passive floor nozzle, ie without brush roller, a very good efficiency and suction power. The use of passive floor nozzles simplifies the construction and thus also the weight of the floor nozzle, which simplifies handling.

Mit der Staubsammeleinheit 2 ist ein Saugschlauch 4 verbunden, der wiederum mit einem Saugrohr 5 verbunden ist. Der Saugschlauch 4 umfasst ein flexibles Material, das insbesondere im Betrieb deformierbar ist. Als Material kommt beispielsweise Kunststoff zum Einsatz. Der Schlauch kann zerstörungsfrei lösbar oder nicht zerstörungsfrei lösbar mit der Staubsammeleinheit 2 verbunden sein.With the dust collecting unit 2, a suction hose 4 is connected, which in turn is connected to a suction pipe 5. The suction hose 4 comprises a flexible material which is deformable in particular during operation. As a material, for example, plastic is used. The hose may be non-destructively releasably or non-destructively releasably connected to the dust collection unit 2.
Das Saugrohr 5 ist starr ausgebildet, so dass es im bestimmungsgemäßen Gebrauch nicht durch einen Nutzer deformierbar ist. Das Material des Saugrohrs 5 kann Kunststoff oder Metall sein. Die Verbindung zwischen dem Saugrohr und dem Saugschlauch kann zerstörungsfrei lösbar oder nicht zerstörungsfrei lösbar ausgebildet sein. An dem Saugrohr 5 ist weiterhin ein Handgriff 6 befestigt.The suction tube 5 is rigid, so that it is not deformed by a user in the intended use. The material of the suction tube 5 may be plastic or metal. The connection between the suction tube and the suction hose can be designed to be non-destructively detachable or non-destructive detachable. At the suction pipe 5, a handle 6 is further attached.
Der Bodenstaubsauger 1 umfasst weiterhin eine Bodendüse 7, die über ein Rohrstück 8 mit einer Motorgebläseeinheit 9 verbunden ist. An der Verbindungsstelle zwischen dem Rohrstück 8 und der Motorgebläseeinheit 9 und/oder zwischen der Bodendüse 7 und dem Rohrstück 8 und/oder der Motorgebläseeinheit 9 und dem Saugrohr 5 kann jeweils ein Kippgelenk, ein Drehgelenk oder ein Drehkippgelenk vorhanden sein. Ein solches Gelenk kann beispielsweise auch durch einen Balgen realisiert werden. In der gezeigten Anordnung wird somit durch Bodendüse 7, Rohrstück 8, Motorgebläseeinheit 9, Saugrohr 5 und Saugschlauch 4 eine durchgängige fluidische bzw. strömungstechnische Verbindung mit der Staubsammeleinheit 2 hergestellt. Die Motorgebläseeinheit 9 ist dabei zwischen der Bodendüse 7 und dem Saugrohr 5 angeordnet, so dass durch die Bodendüse angesaugte Schmutzluft durch die Motorgebläseeinheit 9 hindurch in das Saugrohr 5 strömt.The canister vacuum cleaner 1 further comprises a floor nozzle 7, which is connected via a pipe section 8 with an
Bei der Motorgebläseeinheit 9 handelt es sich somit um einen Dirty-Air-Motor oder Schmutzluftmotor. Es handelt sich insbesondere um eine Motorgebläseeinheit, die ein einstufiges Radialgebläse aufweist. Die Motorgebläseeinheit weist ein Gebläserad auf, dessen Achse im bestimmungsgemäßen Gebrauch parallel zur zu saugenden Fläche und senkrecht zur bestimmungsgemäßen Verschieberichtung der Bodendüse angeordnet ist.The
Der Gebläsedurchmesser kann 60 mm bis 160 mm betragen. Beispielsweise kann eine Motorgebläseeinheit der Firma AMETEK, Inc. verwendet werden, die auch in Soniclean Upright Staubsaugern (z. B. SONICLEAN VT PLUS) eingesetzt wird.The fan diameter can be 60 mm to 160 mm. For example, a motor blower unit from AMETEK, Inc. can be used, which is also used in Soniclean Upright vacuum cleaners (eg SONICLEAN VT PLUS).
Die Motor-Gebläseeinheit des SONICLEAN VT PLUS wurde gemäß DIN EN 60312-1:2014-01 wie oben erläutert charakterisiert. Die Motorgebläseeinheit wurde ohne Staubsaugergehäuse gemessen. Für notwendige Zwischenstücke zum Anschluss an die Messkammer gelten die Ausführungen in Abschnitt 7.3.7.1. Die Tabelle zeigt, dass mit niedrigen Drehzahlen und geringer Aufnahmeleistung hohe Volumenströme erzielt werden.
Im Betrieb wird durch die Motorgebläseeinheit 9 Luft angesaugt. Die Luftströmung tritt dabei durch eine Öffnung der Bodendüse 7 in den Bodenstaubsauger 1 ein, wird durch das Rohrstück 8 und die Motorgebläseeinheit 9 geleitet und strömt danach in das Saugrohr 5. Aufgrund der Anordnung der Motorgebläseeinheit 9 nahe der Bodendüse 7 und - in Luftströmungsrichtung - vor dem Saugrohr 5 und dem Saugschlauch 4, herrscht im Saugrohr 5 und dem Saugschlauch 4 ein Überdruck.In operation, air is sucked in by the
In herkömmlichen Bodenstaubsaugern ist die Motorgebläseeinheit in der Staubsammeleinheit angeordnet, was dazu führt, dass das gesamte System umfassend die Bodendüse, das Saugrohr und den Saugschlauch sowie die Staubsammeleinheit selbst einem Unterdruck ausgesetzt ist. Um eine Deformation insbesondere des Saugrohrs, des Saugschlauchs und/oder der Staubsammeleinrichtung aufgrund des Unterdrucks zu vermeiden, müssen diese Elemente typischerweise verstärkt werden. Bei der in
Bei dem in
Bei der Verwendung insbesondere von einlagigen Staubsaugerfilterbeuteln, bei denen die Beutelwand beispielsweise aus genau einer Vliesstofflage in Form eines Spunbonds besteht, ist die Verwendung eines Ausblasfilters vorteilhaft. Mit dem Ausblasfilter kann Feinstaub gefiltert werden, der im Staubsaugerfilterbeutel nicht abgeschieden wurde. Ein solcher Ausblasfilter kann eine Fläche von wenigstens 800 cm2 aufweisen. Er kann insbesondere plissiert bzw. gefaltet ausgebildet sein, um eine große Oberfläche bei kleinerer Grundfläche (als die Oberfläche) zu haben.When using, in particular, single-layer vacuum cleaner filter bags in which the bag wall consists, for example, of exactly one nonwoven layer in the form of a spunbond, the use of a blow-off filter is advantageous. With the exhaust filter fine dust can be filtered, which was not deposited in the vacuum cleaner filter bag. Such an exhaust filter may have an area of at least 800 cm 2 . In particular, it can be pleated or folded in order to have a large surface area with a smaller base area (than the surface).
Da in der Staubsammeleinheit 2 keine Motorgebläseeinheit angeordnet werden muss, kann die Staubsammeleinheit kompakter und leichter ausgebildet sein als in herkömmlichen Bodenstaubsaugern. Der Saugschlauch 4 hat typischerweise einen Durchmesser in einem Bereich von 25 mm bis 50 mm und eine Länge in einem Bereich von 1000 mm bis 2500 mm. Das Saugrohr 5 hat typischerweise einen Durchmesser in einem Bereich von 25 mm bis 50 mm und eine Länge in einem Bereich von 600 mm bis 1200 mm.Since no engine blower unit needs to be arranged in the dust collecting unit 2, the dust collecting unit can be made more compact and lighter than conventional vacuum cleaners. The suction hose 4 typically has a diameter in a range of 25 mm to 50 mm and a length in a range of 1000 mm to 2500 mm. The suction pipe 5 typically has a diameter in a range of 25 mm to 50 mm and a length in a range of 600 mm to 1200 mm.
Das Saugrohr 5 ist starr, der Saugschlauch 4 flexibel ausgebildet.The suction tube 5 is rigid, the suction hose 4 is flexible.

Die Staubsammeleinheit 2 weist einen Ausblasfilter auf, mit dem Feinstaub gefiltert wird, der im Fliehkraftabscheider nicht abgeschieden wurde. Dieser Ausblasfilter kann eine Fläche von wenigstens 800 cm2 aufweisen. Er kann insbesondere plissiert bzw. gefaltet ausgebildet sein, um eine große Oberfläche bei kleinerer Grundfläche zu haben. Dabei kann der Ausblasfilter in einer Halterung vorgesehen sein, wie sie in der Europäischen Patentanmeldung Nr.
Es versteht sich, dass die in
Zusätzlich zu der in den gezeigten Beispielen eingesetzten einen Motorgebläseeinheit kann der Bodenstaubsauger auch eine zweite, unterstützende Motorgebläseeinheit aufweisen. Es hat sich herausgestellt, dass die Verwendung von zwei Motorgebläseeinheit im Gebrauch des Bodenstaubsaugers zu einem geringeren Saugkraftverlust führen kann, verglichen mit dem Einsatz einer einzigen Motorgebläseeinheit, selbst wenn die Summe der elektrischen Aufnahmeleistung der zwei Motorgebläseeinheiten gleich der elektrischen Aufnahmeleistung der einen Motorgebläseeinheit ist.In addition to the one motor fan unit used in the examples shown, the cylinder vacuum cleaner may also include a second, auxiliary motor fan unit. It has been found that the use of two engine blower units in the use of the canister vacuum can result in lower suction power loss compared to the use of a single engine blower unit, even if the sum of the electrical power consumption of the two engine blower units is equal to the electrical power consumption of the one engine blower unit.
Die zweite Motorgebläseeinheit kann als Dirty-Air-Motor ausgebildet sein und fluidisch vor der Staubsammeleinheit angeordnet sein, so das Schmutzluft auch durch die zweite Motorgebläseeinheit hindurch strömt. Die beiden Motorgebläseeinheiten können gleiche oder unterschiedliche elektrische Leitungsaufnahmen aufweisen.The second engine blower unit may be configured as a dirty-air engine and fluidly arranged in front of the dust collection unit, so that dirty air also flows through the second engine blower unit. The two motor fan units may have the same or different electrical line recordings.
Alternativ kann die zweite Motorgebläseeinheit als Clean-Air-Motor ausgebildet sein und fluidisch hinter der Staubsammeleinheit angeordnet sein. Beispielsweise kann eine Motorgebläseeinheit der Firma Domel mit der Typenbezeichnung 467.3.601-4 (zu beziehen über Domel, d.o.o Otoki 21, 4228 elezniki, Slovenija) verwendet werden.Alternatively, the second engine blower unit may be formed as a clean-air engine and be arranged fluidly behind the dust-collecting unit. For example, a motor blower unit from the company Domel with the type designation 467.3.601-4 (available from Domel, doo Otoki 21, 4228 elezniki, Slovenija).
In beiden Ausführungsbeispielen ist es nicht erforderlich, dass an oder in der Bodendüse 7 eine Bürstenwalze (bspw. eine Klopfbürste und/oder rotierende Bürste) vorgesehen ist.In both exemplary embodiments, it is not necessary for a brush roller (for example a knock brush and / or rotating brush) to be provided on or in the floor nozzle 7.
