Definitions
- the invention relates to a soleplate, a vacuum cleaner nozzle and a vacuum cleaner.
- a soleplate for a vacuum cleaner nozzle is from EP 3 047 775 B1 known.
- the soleplate described there has a suction mouth formed on its underside, which is delimited by a front and a rear suction mouth edge, a sliding bevel in the working direction in front of the suction mouth, an inclined sliding surface in the working direction behind the suction mouth and a suction opening opening into the suction mouth.
- a horizontal plateau is arranged between the front slide-on bevel and the front edge of the suction mouth, which plateau extends at the level of the front edge of the suction mouth over the entire length of the front edge of the suction mouth, parallel thereto.
- the slide-on slope has an incline of between 5° and 7° or is designed as a crowned surface.
- the design of the suction mouth is only designed for one application. Dust is removed from the subsurface or carpet, but not from hard floors or cracks with joints.
- the EP 3 494 852 A1 and the DE 10 2016 101051 A1 1 disclose a sliding base for a vacuum cleaner nozzle with a suction mouth which is delimited by a front and a rear edge of the suction mouth.
- An inclined sliding surface is arranged behind the suction mouth in the working direction, with a horizontal plateau being arranged between the inclined sliding surface and the rear edge of the suction mouth.
- the U.S. 2019 / 174983 A1 discloses a sliding base for a vacuum cleaner nozzle on the sliding surfaces of which air guiding elements are arranged, the air guiding elements protruding from the sliding surface in the direction of a floor surface to be treated.
- the GB 2 214 787 A discloses a sliding soleplate for a vacuum cleaner nozzle with an inclined sliding surface behind a suction mouth, the sliding surface being arranged between a sealing lip and a horizontal plateau.
- the invention therefore addresses the problem of providing a soleplate, a vacuum cleaner nozzle and a vacuum cleaner which are designed to remove dust both from a carpet and also from dirt on a hard floor with cracks and/or gaps.
- the advantages that can be achieved with the invention consist, in addition to a low sliding resistance, in the good suction properties when using the sliding soleplate in a vacuum cleaner.
- the suction mouth edges seal the suction mouth on the bottom side when in use, so that an efficient negative pressure can be built up. Therefore, by means of the soleplate, dust and/or dirt can be efficiently removed both from a carpet and from a hard floor with cracks and/or gaps. At the same time, if the negative pressure is too high, sliding forces ( ⁇ 30N) are not exceeded.
- the front edge of the suction mouth extends without interruption over the entire working width of the soleplate and delimits at both ends of the suction mouth an end section of the suction mouth designed for edge suction.
- Information on direction and position relates to an operational working position and direction of the soleplate.
- the rear edge of the suction mouth extends without interruption over the entire working width of the soleplate and delimits an end section of the suction mouth designed for edge suction at both ends of the suction mouth.
- the horizontal plateau is arranged, which extends at the level of the rear edge of the suction mouth over the entire length of the rear edge of the suction mouth parallel to the latter.
- the rear edge of the suction mouth and the horizontal plateau adjoining the rear edge of the suction mouth form a further boundary of the suction mouth. This further boundary extends without interruption over the entire working width of the suction mouth and is also important for the suction power.
- Both - that is, the front and the rear - suction mouth edges can seal the suction mouth on the bottom side when used, and this allows an efficient negative pressure to build up over the entire working surface of the sliding sole. Furthermore, good suction properties are achieved even with a low air output of the vacuum cleaner having the sliding soleplate.
- the front edge of the suction mouth and the rear edge of the suction mouth are each designed as a straight edge in a plan view of the sliding soleplate.
- the horizontal plateau adjoining the rear edge of the suction mouth preferably extends with a constant width parallel to the rear edge of the suction mouth.
- the end sections of the suction mouth can be open or closed at the end for edge suction.
- the suction mouth opening is preferably arranged centrally between the two ends of the suction mouth.
- the horizontal plateau preferably has an approach angle in the range from 30 to 45°, preferably 35 to 40°.
- the horizontal plateau has a length of 8.50 to 10.50 mm, preferably 9.00 to 10.00 mm.
- the length and the width of the rear edge of the suction mouth extend perpendicularly or substantially perpendicularly to one another.
- the width of the rear edge of the suction mouth extends parallel to the working width.
- the horizontal plateau preferably has a radius in the range of 0.5 to 1.5 millimeters to the suction mouth opening.
- the approach angle of the horizontal plateau is preferably provided with a further radius in the range of 2.5 to 3.5 millimeters.
- the height of the horizontal plateau is 0.50 to 1.50 mm, preferably 0.75 to 1.25 mm, higher than the height of the front edge of the suction mouth, based on an operational set-up position of the sliding sole. That is, if the soleplate in their operational set-up position of the soleplate is arranged on the ground, a distance between the horizontal plateau and the ground is 0.5 to 1.5 mm, preferably 0.75 to 1.25 mm, greater than a distance between the front edge of the suction mouth and the ground. In this case, too, the front and rear suction mouth edges delimit the suction mouth, but the suction mouth opening is larger than the suction mouth because the rear suction mouth edge does not rest on the ground when the front suction mouth edge is arranged on the ground.
- air guide elements are arranged on the slide-on slope, with the air guide elements protruding from the slide-on slope in the direction of a floor surface to be treated, based on an operational working position of the sliding sole.
- the air guide elements are arranged on the slide-on slope in such a way that the air guide elements form air ducts. These air channels extend essentially parallel to the main direction of movement of the floor nozzle in an intended cleaning operation.
- the air guide elements have an approximately triangular basic shape.
- the air guide elements are arranged on the slide-on slope in such a way that the air channels formed taper in the direction of the suction mouth.
- the air guide elements partially seal the soleplate from the ground in the area of the front edge of the suction nozzle and at the same time allow larger dirt particles to be picked up. In particular, an unintentional displacement of larger dirt particles through a vacuum cleaner nozzle according to the invention during cleaning operation is avoided in this way.
- the sliding sole preferably also has a sealing lip, which is arranged in such a way that the inclined sliding surface is arranged between the sealing lip and the horizontal plateau.
- the sealing lip also supports the bottom sealing of the suction mouth. If the distance between the horizontal plateau and the ground is greater than the distance between the front edge of the suction mouth and the ground, the sealing lip is preferably arranged in a predetermined area of the suction mouth opening.
- the sealing lip is preferably arranged in the rear area of the suction mouth opening.
- the sealing lip preferably delimits the suction mouth opening.
- the sealing lip preferably extends without interruption over the entire working width of the soleplate. As a result, the sealing lip has the function of sealing the rear suction mouth and thus sucking in dirt even more efficiently during use. In particular with deep grooves and/or gaps on a hard floor, the suction mouth continues to be optimally sealed by means of the sealing lip.
- each brush seal is preferably designed as a brush base.
- Each brush seal is preferably formed from plastic into which trimmings may be woven. More preferably, the brush seal is formed from extruded PP (polypropylene) into which is woven a braid of multifilament yarn.
- the invention also relates to a vacuum cleaner nozzle which has the sliding sole according to one or more of the embodiments described above.
- the soleplate ensures efficient dust pick-up by the vacuum cleaner nozzle.
- the soleplate represents a lower part of the vacuum cleaner nozzle, based on an operational working position of the vacuum cleaner nozzle.
- the vacuum cleaner nozzle is preferably an electronic vacuum cleaner nozzle.
- the vacuum cleaner nozzle preferably has at least one brush device.
- the vacuum cleaner nozzle preferably also has one or more wheels.
- the invention relates to a vacuum cleaner which has the vacuum cleaner nozzle according to one or more of the embodiments described above.
- the vacuum cleaner has the sliding soleplate according to one or more of the embodiments described above.
- the suction mouth and the suction mouth limitation of the soleplate are designed in such a way that an air flow sucked in when the vacuum cleaner is operating flows around the edges of the suction mouth at high air speed, so that dust is loosened from a surface such as a carpet or hard floor and is effectively entrained by the air flow.
- the vacuum cleaner is preferably designed as a hand-held vacuum cleaner.

Erfindungsgemäß wird dieses Problem durch eine Gleitsohle mit den Merkmalen des Patentanspruchs 1, eine Staubsaugerdüse mit den Merkmalen des Patentanspruchs 10 und einen Staubsauger mit den Merkmalen des Patentanspruchs 11 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention, this problem is solved by a soleplate having the features of
Die mit der Erfindung erreichbaren Vorteile bestehen neben einem geringen Gleitwiderstand in den guten Saugeigenschaften bei Verwendung der Gleitsohle in einem Staubsauger. Die Saugmundkanten dichten den Saugmund bodenseitig bei Anwendung ab, so dass ein effizienter Unterdruck aufbaubar ist. Daher kann mittels der Gleitsohle effizient Staub und/oder Schmutz sowohl von einem Teppich als auch von einem Hartboden mit Ritzen und/oder Fugen entfernt werden. Gleichzeitig werden bei einem zu hohen Unterdruck bei Anwendung Schiebekräfte (<30N) nicht überschritten.The advantages that can be achieved with the invention consist, in addition to a low sliding resistance, in the good suction properties when using the sliding soleplate in a vacuum cleaner. The suction mouth edges seal the suction mouth on the bottom side when in use, so that an efficient negative pressure can be built up. Therefore, by means of the soleplate, dust and/or dirt can be efficiently removed both from a carpet and from a hard floor with cracks and/or gaps. At the same time, if the negative pressure is too high, sliding forces (<30N) are not exceeded.
Die Erfindung betrifft eine Gleitsohle für eine Staubsaugerdüse, aufweisend
- einen an ihrer Unterseite eingeformten Saugmund, der von einer vorderen und einer hinteren Saugmundkante begrenzt ist,
- eine Aufgleitschräge in Arbeitsrichtung vor dem Saugmund,
- eine geneigte Gleitfläche in Arbeitsrichtung hinter dem Saugmund und
- eine in den Saugmund mündende Saugmundöffnung,
- wobei sich die hintere Saugmundkante ohne Unterbrechung über die gesamte Arbeitsbreite der Gleitsohle erstreckt und an beiden Enden des Saugmundes einen zur Randabsaugung ausgelegten Endabschnitt des Saugmundes begrenzt, und
- wobei zwischen der geneigten Gleitfläche und der hinteren Saugmundkante ein horizontales Plateau angeordnet ist, welches sich auf dem Niveau der hinteren Saugmundkante über die gesamte Breite der hinteren Saugmundkante parallel zu dieser erstreckt und welches eine Länge von mindestens 8,5 mm aufweist, wobei die Länge und die Breite der hinteren Saugmundkante senkrecht oder im Wesentlichen senkrecht zueinander ausgebildet sind und die Breite der hinteren Saugmundkante parallel zur Arbeitsbreite verläuft.
- a suction mouth formed on its underside, which is delimited by a front and a rear suction mouth edge,
- a sliding slope in the working direction in front of the suction mouth,
- an inclined sliding surface in the working direction behind the suction mouth and
- a suction mouth opening opening into the suction mouth,
- wherein the rear edge of the suction mouth extends without interruption over the entire working width of the soleplate and at both ends of the suction mouth delimits an end section of the suction mouth designed for edge suction, and
- a horizontal plateau being arranged between the inclined sliding surface and the rear edge of the suction mouth, which extends at the level of the rear edge of the suction mouth over the entire width of the rear edge of the suction mouth, parallel thereto and which has a length of at least 8.5 mm, the length and the width of the rear edge of the suction mouth is perpendicular or essentially perpendicular to one another and the width of the rear edge of the suction mouth runs parallel to the working width.
Die vordere Saugmundkante erstreckt sich ohne Unterbrechung über die gesamte Arbeitsbreite der Gleitsohle und begrenzt an beiden Enden des Saugmundes einen zur Randabsaugung ausgelegten Endabschnitt des Saugmundes. Richtungs- und Positionsangaben beziehen sich auf eine betriebsgemäße Arbeitsposition und -richtung der Gleitsohle.The front edge of the suction mouth extends without interruption over the entire working width of the soleplate and delimits at both ends of the suction mouth an end section of the suction mouth designed for edge suction. Information on direction and position relates to an operational working position and direction of the soleplate.
Die hintere Saugmundkante erstreckt sich ohne Unterbrechung über die gesamte Arbeitsbreite der Gleitsohle und begrenzt an beiden Enden des Saugmundes einen zur Randabsaugung ausgelegten Endabschnitt des Saugmundes. Zwischen der geneigten Gleitfläche und der hinteren Saugmundkante ist das horizontale Plateau angeordnet, das sich auf dem Niveau der hinteren Saugmundkante über die gesamte Länge der hinteren Saugmundkante parallel zu dieser erstreckt. Die hintere Saugmundkante und das an die hintere Saugmundkante angrenzende horizontale Plateau bilden eine weitere Berandung des Saugmundes. Diese weitere Berandung erstreckt sich ohne Unterbrechung über die gesamte Arbeitsbreite des Saugmundes und ist ebenfalls für die Saugleistung wichtig. Beide - also die vordere und die hintere - Saugmundkanten können den Saugmund bodenseitig bei Anwendung abdichten, und dadurch kann sich ein effizienter Unterdruck über die gesamte Arbeitsfläche der Gleitsohle aufbauen. Weiterhin wird auch bei einer geringen Luftleistung des die Gleitsohle aufweisenden Staubsaugers eine gute Saugeigenschaft erzielt.The rear edge of the suction mouth extends without interruption over the entire working width of the soleplate and delimits an end section of the suction mouth designed for edge suction at both ends of the suction mouth. Between the inclined sliding surface and the rear edge of the suction mouth, the horizontal plateau is arranged, which extends at the level of the rear edge of the suction mouth over the entire length of the rear edge of the suction mouth parallel to the latter. The rear edge of the suction mouth and the horizontal plateau adjoining the rear edge of the suction mouth form a further boundary of the suction mouth. This further boundary extends without interruption over the entire working width of the suction mouth and is also important for the suction power. Both - that is, the front and the rear - suction mouth edges can seal the suction mouth on the bottom side when used, and this allows an efficient negative pressure to build up over the entire working surface of the sliding sole. Furthermore, good suction properties are achieved even with a low air output of the vacuum cleaner having the sliding soleplate.
Bevorzugt sind die vordere Saugmundkante und in die hintere Saugmundkante in einer Draufsicht auf die Gleitsohle jeweils als gerade Kante ausgebildet. Bevorzugt erstreckt sich das an die hintere Saugmundkante angrenzende horizontale Plateau mit einer konstanten Breite parallel zu der hinteren Saugmundkante.Preferably, the front edge of the suction mouth and the rear edge of the suction mouth are each designed as a straight edge in a plan view of the sliding soleplate. The horizontal plateau adjoining the rear edge of the suction mouth preferably extends with a constant width parallel to the rear edge of the suction mouth.
Die Endabschnitte des Saugmundes können zur Randabsaugung endseitig offen oder geschlossen sein. Die Saugluft, die bei Anwendung der Gleitsohle in dem Staubsauger an den Saugmundkanten in den Saugmund eintritt, strömt der in den Saugmund mündenden Saugmundöffnung zu. Die Saugmundöffnung ist bevorzugt mittig zwischen den beiden Enden des Saugmundes angeordnet.The end sections of the suction mouth can be open or closed at the end for edge suction. The suction air that enters the suction mouth at the edges of the suction mouth when the sliding soleplate is used in the vacuum cleaner, flows towards the suction mouth opening that opens into the suction mouth. The suction mouth opening is preferably arranged centrally between the two ends of the suction mouth.
Zur Erzielung einer guten Abdichtung zum Untergrund sind die folgenden parametrischen Gestaltungen des horizontalen Plateaus vorteilhaft: Bevorzugt weist das horizontale Plateau einen Anlaufwinkel im Bereich von 30 bis 45°, bevorzugt 35 bis 40°, auf. Alternativ oder zusätzlich bevorzugt weist das horizontale Plateau eine Länge von 8,50 bis 10,50 mm, bevorzugt 9,00 bis 10,00, mm auf. Die Länge und die Breite der hinteren Saugmundkante erstrecken sich senkrecht oder im Wesentlichen senkrecht zueinander. Die Breite der hinteren Saugmundkante erstreckt sich parallel zur Arbeitsbreite.The following parametric designs of the horizontal plateau are advantageous for achieving a good seal to the substrate: The horizontal plateau preferably has an approach angle in the range from 30 to 45°, preferably 35 to 40°. Alternatively or additionally preferably, the horizontal plateau has a length of 8.50 to 10.50 mm, preferably 9.00 to 10.00 mm. The length and the width of the rear edge of the suction mouth extend perpendicularly or substantially perpendicularly to one another. The width of the rear edge of the suction mouth extends parallel to the working width.
Bevorzugt weist das horizontale Plateau einen Radius im Bereich von 0,5 bis 1,5 Millimetern zur Saugmundöffnung auf. Bevorzugt ist der Anlaufwinkel des horizontalen Plateaus mit einem weiteren Radius im Bereich von 2,5 bis 3,5 Millimetern versehen.The horizontal plateau preferably has a radius in the range of 0.5 to 1.5 millimeters to the suction mouth opening. The approach angle of the horizontal plateau is preferably provided with a further radius in the range of 2.5 to 3.5 millimeters.
In einer bevorzugten Ausführungsform ist eine Höhe des horizontalen Plateaus um 0,50 bis 1,50 mm, bevorzugt 0,75 bis 1,25 mm, höher als die Höhe der vorderen Saugmundkante, bezogen auf eine betriebsgemäße Aufstellposition der Gleitsohle. D.h., wenn die Gleitsohle in ihrer betriebsgemäßen Aufstellposition der Gleitsohle auf dem Untergrund angeordnet ist, ist ein Abstand des horizontalen Plateaus zum Untergrund um 0,5 bis 1,5 mm, bevorzugt 0,75 bis 1,25mm, größer als ein Abstand der vorderen Saugmundkante zum Untergrund. Auch in diesem Fall begrenzen die vordere und die hintere Saugmundkante den Saugmund, die Saugmundöffnung ist jedoch größer als der Saugmund, weil die hintere Saugmundkante nicht auf dem Untergrund aufliegt, wenn die vordere Saugmundkante auf dem Untergrund angeordnet ist.In a preferred embodiment, the height of the horizontal plateau is 0.50 to 1.50 mm, preferably 0.75 to 1.25 mm, higher than the height of the front edge of the suction mouth, based on an operational set-up position of the sliding sole. That is, if the soleplate in their operational set-up position of the soleplate is arranged on the ground, a distance between the horizontal plateau and the ground is 0.5 to 1.5 mm, preferably 0.75 to 1.25 mm, greater than a distance between the front edge of the suction mouth and the ground. In this case, too, the front and rear suction mouth edges delimit the suction mouth, but the suction mouth opening is larger than the suction mouth because the rear suction mouth edge does not rest on the ground when the front suction mouth edge is arranged on the ground.
Zudem ist es bevorzugt, dass auf der Aufgleitschräge Luftleitelemente angeordnet sind, wobei die Luftleitelemente von der Aufgleitschräge in Richtung einer zu bearbeitenden Bodenfläche vorstehen, bezogen auf eine betriebsgemäße Arbeitsposition der Gleitsohle. Die Luftleitelemente sind dabei in der Form auf der Aufgleitschräge angeordnet, dass die Luftleitelemente Luftkanäle ausbilden. Diese Luftkanäle erstrecken sich im Wesentlichen parallel zur Hauptbewegungsrichtung der Bodendüse in einem bestimmungsgemäßen Reinigungsbetrieb. Die Luftleitelemente weisen eine annähernd dreiecksförmige Grundform auf. Dabei sind die Luftleitelemente so auf der Aufgleitschräge angeordnete, dass sich die ausgebildeten Luftkanäle in Richtung des Saugmundes verjüngen. Die Luftleitelemente bewirken eine teilweise Abdichtung der Gleitsohle zum Untergrund im Bereich der vorderen Saugmundkante und ermöglichen gleichzeitig die Aufnahme von größeren Schmutzpartikeln. Insbesondere ein ungewolltes Verschieben von größeren Schmutzpartikeln durch eine erfindungsgemäße Staubsaugerdüse im Reinigungsbetrieb wird auf diese Weise vermieden.In addition, it is preferred that air guide elements are arranged on the slide-on slope, with the air guide elements protruding from the slide-on slope in the direction of a floor surface to be treated, based on an operational working position of the sliding sole. The air guide elements are arranged on the slide-on slope in such a way that the air guide elements form air ducts. These air channels extend essentially parallel to the main direction of movement of the floor nozzle in an intended cleaning operation. The air guide elements have an approximately triangular basic shape. The air guide elements are arranged on the slide-on slope in such a way that the air channels formed taper in the direction of the suction mouth. The air guide elements partially seal the soleplate from the ground in the area of the front edge of the suction nozzle and at the same time allow larger dirt particles to be picked up. In particular, an unintentional displacement of larger dirt particles through a vacuum cleaner nozzle according to the invention during cleaning operation is avoided in this way.
Bevorzugt weist die Gleitsohle weiterhin eine Dichtlippe auf, die derart angeordnet ist, dass die geneigte Gleitfläche zwischen der Dichtlippe und dem horizontalen Plateau angeordnet ist. Die Dichtlippe unterstützt weiterhin die bodenseitige Abdichtung des Saugmundes. Wenn der Abstand des horizontalen Plateaus zum Untergrund größer als der Abstand der vorderen Saugmundkante zum Untergrund ist, ist die Dichtlippe bevorzugt in einem vorbestimmten Bereich der Saugmundöffnung angeordnet. Bevorzugt ist die Dichtlippe im hinteren Bereich der Saugmundöffnung angeordnet. Bevorzugt begrenzt die Dichtlippe die Saugmundöffnung. Die Dichtlippe erstreckt sich bevorzugt ohne Unterbrechung über die gesamte Arbeitsbreite der Gleitsohle. Dadurch hat die Dichtlippe die Funktion, dass der hintere Saugmund abgedichtet und somit der Schmutz bei Anwendung noch effizienter eingesaugt wird. Insbesondere bei tiefen Rillen und/oder Fugen auf einem Hartboden wird der Saugmund weiterhin optimal mittels der Dichtlippe abgedichtet.The sliding sole preferably also has a sealing lip, which is arranged in such a way that the inclined sliding surface is arranged between the sealing lip and the horizontal plateau. The sealing lip also supports the bottom sealing of the suction mouth. If the distance between the horizontal plateau and the ground is greater than the distance between the front edge of the suction mouth and the ground, the sealing lip is preferably arranged in a predetermined area of the suction mouth opening. The sealing lip is preferably arranged in the rear area of the suction mouth opening. The sealing lip preferably delimits the suction mouth opening. The sealing lip preferably extends without interruption over the entire working width of the soleplate. As a result, the sealing lip has the function of sealing the rear suction mouth and thus sucking in dirt even more efficiently during use. In particular with deep grooves and/or gaps on a hard floor, the suction mouth continues to be optimally sealed by means of the sealing lip.
Für eine seitliche Abdichtung des Saugmundes können eine oder mehrere Dichtlippen eingesetzt werden, die in Arbeitsrichtung seitlich zum Saugmund angeordnet sind. Bevorzugt weist die Gleitsohle eine oder mehrere Bürstendichtungen auf, die in Arbeitsrichtung seitlich zum Saugmund angeordnet sind. Dadurch wird eine seitliche Abdichtung des Saugmunds bereitgestellt. Bevorzugt ist jede Bürstendichtung als ein Bürstenfuß ausgebildet. Jede Bürstendichtung ist bevorzugt aus Kunststoff ausgebildet, in das ein Besatz eingewoben sein kann. Bevorzugter ist die Bürstendichtung aus extrudiertem PP (Polypropylen) ausgebildet, in das ein Besatz aus Multifilament-Garn eingewoben ist.For lateral sealing of the suction mouth, one or more sealing lips can be used, which are arranged laterally to the suction mouth in the working direction. The sliding soleplate preferably has one or more brush seals, which are arranged laterally to the suction mouth in the working direction. This creates a lateral seal for the suction mouth provided. Each brush seal is preferably designed as a brush base. Each brush seal is preferably formed from plastic into which trimmings may be woven. More preferably, the brush seal is formed from extruded PP (polypropylene) into which is woven a braid of multifilament yarn.
