- the vacuum cleaning device comprising at least one turbine and a filter as suction components.
- a specific nesting of the suction components within the vacuum cleaner is provided, in which in particular the mentioned suction components are arranged inclined or tilted with respect to a horizontal plane.
- the invention relates to a vacuum cleaning device which has a proposed arrangement of components in which individual components in the suction head of the vacuum cleaning device form a triangle with one another.
- vacuum cleaning devices are known, which are used in particular on construction sites in order to suck off dust that occurs in connection with the use of machine tools such as drilling or grinding devices.
- construction site vacuums usually comprise a suction head in an upper area and a collecting container for the vacuumed up dust in a lower area of the vacuum cleaner.
- vacuum cleaners are preferably also referred to as industrial vacuum cleaners in the context of the invention.
- the suction components such as turbine, motor, filter, filter cleaning unit, etc., are arranged essentially vertically and / or horizontally within the vacuum cleaner device.
- the rigid vertical or horizontal alignment of suction components can lead to individual components having to be cabled to one another in a complex manner if they are not optimally arranged with respect to one another within the suction device. This represents a possibly unnecessary outlay on resources, which makes such a vacuum cleaner device possibly susceptible to errors or leads to increased repair and / or maintenance costs.
- a rigid vertical or horizontal arrangement of suction components can lead to increased sealing costs. On the one hand, this can manifest itself in the fact that a complex sealing concept must be used. However, it can also manifest itself in an increased cost of materials. Both effects are undesirable in relation to a vacuum cleaner device, since they can lead to increased wear and tear or additional weight and thus to an additional financial burden when operating the vacuum cleaner device. It has also been shown that conventional vacuum cleaning devices, in which the suction components are oriented vertically and / or horizontally with respect to the side walls, lead to increased performance losses.
- the object of the present invention is to solve the problems described above and to provide a vacuum cleaning device in which the individual suction components are arranged relative to one another in a space-saving manner.
- the seal should be simple and uncomplicated.
- a vacuum cleaner that is powerful in relation to the size of the vacuum cleaner device is to be provided, in which, in particular, simple but effective air guidance is possible. It would also be desirable if the filter or a filter unit of the vacuum cleaner to be provided could be removed from the rear of the vacuum cleaner.
- the object is achieved by an arrangement of components in a vacuum cleaner, the vacuum cleaner comprising at least one turbine, a filter and a filter cleaning unit in a suction head.

- the triangle results in particular in a side view of the suction head of the vacuum cleaning device.
- the three mentioned teat components preferably form the corner points of the triangle.
- the turbine and the filter cleaning unit preferably form an essentially horizontal upper edge of the triangle, with the turbine in a front Area of the suction head of the vacuum cleaning device is arranged and the filter cleaning unit in a rear area.
- the triangle that forms is preferably an essentially right-angled triangle, the right angle of which is in the area of the filter cleaning device.
- the horizontal upper edge of the triangle which is preferably arranged between the turbine and the filter cleaning unit, preferably represents one of the two legs of the essentially right-angled triangle.
- the second leg of the essentially right-angled triangle is preferably arranged between the filter cleaning unit and the filter, while the Hypotenuse is present between a geometric center of gravity of the filter and a geometric center of gravity of the turbine.
- the triangle between the suction components is spanned in particular in that the turbine is arranged essentially next to the filter cleaning unit, the filter is arranged essentially below the filter cleaning unit and the turbine is arranged essentially obliquely above the filter.
- the individual components are tilted to a horizontal and / or vertical axis of the suction head of the vacuum cleaner device.
- an imaginary first central axis through the filter of the vacuum cleaner with an imaginary horizontal plane forms a first angle between 10 to 20 degrees and an imaginary second central axis through the turbine of the vacuum cleaner with an imaginary horizontal plane forms a second Forms angles between 145 to 155 degrees.
- the aforementioned angular sizes preferably enable the triangular arrangement of the suction components turbine, filter cleaning unit and filter.
- the triangular arrangement of the suction components in the suction head of the vacuum cleaning device preferably enables a compact design for the vacuum cleaning device, in which a number of advantages can be achieved through a targeted nesting of individual suction components.
- the compact arrangement of the suction components, in particular the filter and the turbine the number of parts to be installed in the vacuum cleaning device can be reduced.
- This can advantageously be achieved in that a base plate of the suction head forms a central point at which the suction components can be arranged.
- the inclination of the components in the above-mentioned angular ranges which advantageously leads to the triangular arrangement of the suction components, preferably enables the advantageous, space-saving nesting of the components and the moving of the components together in the suction head.
- the proposed vacuum cleaning device can be designed and manufactured in a simple manner and is advantageously particularly low-maintenance.
- the efficiency of the vacuum cleaner can be increased considerably because the vacuum cleaner can be designed to be particularly compact and space-saving. This also facilitates their handling or use.
- the targeted tilting or inclined arrangement of suction components such as turbines or filters can advantageously increase the available usable container volume so that a larger amount of dust can be picked up and collected with the proposed vacuum cleaner.
- a particular advantage of the proposed component arrangement for a vacuum cleaning device is that the filter of the vacuum cleaning device can be removed or replaced on the rear of the vacuum cleaning device. This enables an optimized air flow within the vacuum cleaner. In particular, the volume flow and pressure losses can be significantly reduced due to the improved air routing within the vacuum cleaner.
- the filter and the turbine are arranged tilted with respect to a horizontal plane.
- the mentioned suction components are inclined within the suction head of the vacuum cleaner.
- the inclination of the individual nipple components is defined by an angle of inclination which is formed by an imaginary central axis through the nipple component and an imaginary horizontal plane.
- the imaginary central axis through the filter is referred to in the sense of the invention as the first imaginary central axis of the vacuum cleaner, while the imaginary central axis through the turbine is referred to as the second imaginary central axis of the vacuum cleaner. Accordingly, the angle of inclination of the filter is referred to as the first angle.
- This first angle is preferably in a range between 10 to 20 degrees, in particular inclination angle values between 13 and 17 degrees and particularly preferably of 15 degrees being preferred for the filter. In other words, it is preferred that the first angle is between 13 and 17 degrees and particularly preferably 15 degrees.
- the corresponding first angle is in the Figure 1 indicated.
- all values between 10 and 20 degrees can be preferred, in particular the values 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 and all rational and non-rational intermediate values.
- values between 5 and 25 degrees can also be preferred, in particular 5, 6, 7, 8, 9 or 21, 22, 23, 24, or 25, as well as all rational and non-rational intermediate values.
- the size of the angle of inclination is preferably determined according to the mathematical point of view in that the horizontal plane is viewed as the positive x-axis of a Cartesian coordinate system and the axis through the filter or the turbine as a limb or pointer, with the included angle between the x-axis and the leg preferably corresponds to the angle of inclination for the respective component.
- the person skilled in the art recognizes that the first imaginary central axis, which preferably runs centrally through the filter, lies in the first quadrant of such a Cartesian coordinate system, while the second imaginary central axis, which preferably runs centrally through the turbine, lies in the second quadrant of such a Cartesian coordinate system Coordinate system.
- the angle of inclination of the turbine is referred to as the second angle in the context of the invention. This is preferably in a range between 145 to 155 degrees, with inclination angle values between 148 and 152 degrees and particularly preferably 150 degrees being preferred for the filter. In other words, it is preferred that the second angle is between 148 and 152 degrees and particularly preferably 150 degrees. If the above-described x-axis is extended beyond the y-axis of the coordinate system into the second quadrant and this "negative x-axis" is used as the starting point for determining the size of the second angle of inclination for the turbine, a second angle of inclination results in one Range from 25 to 35 degrees, preferably 28 to 32 degrees and particularly preferably from 30 degrees.
- all values between 145 and 155 degrees can be preferred, in particular the values 145, 146, 147, 148, 149, 150, 151, 152, 153, 154, 155 and all rational and non-rational intermediate values.
- values between 140 and 160 degrees can also be preferred, in particular 140, 141, 142, 143, 144 or 156, 157, 158, 159 or 160, as well as all rational and non-rational intermediate values.
- This second angle which is defined by the negative x-axis and the central axis through the turbine, is also indicated in FIG.
- suction components filter and turbine are not aligned horizontally or vertically with respect to the side walls of the suction head of the vacuum cleaning device, but the mentioned suction components assume an inclined position with respect to the outer walls of the vacuum cleaning device by being tilted relative to the imaginary horizontal plane.
- the terms “horizontal” and “vertical” preferably relate to the side walls which are mostly oriented essentially perpendicular to the ground the vacuum cleaner, where the term “horizontal” in the context of the invention preferably means that an object is arranged essentially parallel to the ground or essentially perpendicular to a side wall of the vacuum cleaner, while the term “vertical” in the context of the invention preferably means that an object is arranged essentially perpendicular to the ground or essentially parallel to a side wall of the vacuum cleaner.
- a horizontal plane that can be imagined through the vacuum cleaner is thus an imaginary plane that runs essentially parallel to the earth's surface.
- Minimal deviations from the earth's surface in a range of 0 to 5 degrees are preferably covered by the term "horizontal" within the meaning of the invention, since measurement inaccuracies can occur or because the earth's surface is not always completely flat.
- a tilted or inclined arrangement of a teat component in relation to such a virtual horizontal plane preferably means in the context of the invention that an axis, which preferably runs as an imaginary central axis through the inclined or tilted teat component, encloses an angle with the horizontal plane that is significantly greater than 0 is. In the context of the invention, this angle is referred to as the "angle of inclination" of the corresponding suction component.
- the invention is thus characterized by an inclined position of the suction components turbine and filter.
- the turbine of the vacuum cleaner is preferably set up to generate the suction flow for the dust - for example on a construction site - by generating an air flow.
- a negative pressure is generated in the vacuum cleaner, with which the suction flow can be provided for suctioning off the dust.
- the vacuum cleaning device can have further filter or filter elements.
- the tilted filter can also be referred to as a filter cassette or as a main filter, the filter cassette advantageously now being able to be removed from the proposed vacuum cleaner device from behind due to the proposed compact design.
- the terms "front” and “rear” or “rear” are not unclear terms for the person skilled in the art in relation to a vacuum cleaning device, because the person skilled in the art is familiar with the design and arrangement of the components of the Vacuum cleaner can recognize which is the front and which is the back of the vacuum cleaner.
- a control display with buttons and control elements can be provided on the front.
- the proposed vacuum cleaner can therefore include a filter cleaning unit with which the filter or the filter elements of the vacuum cleaner can be cleaned manually or automatically.
- the turbine of the proposed vacuum cleaner is arranged next to this filter cleaning unit and that the filter is arranged below this filter cleaning unit. The inventors have recognized that this arrangement is particularly advantageous because it enables efficient cleaning of the filter through an optimized alignment of the cleaning unit relative to the filter.
- the filter cleaning unit is located directly above the filter, which in a particularly preferred embodiment of the invention is tilted by 15 degrees with respect to a horizontal plane of the vacuum cleaner device.
- This tilting in particular, significantly increases the container volume available for receiving dust, so that advantageously more dust can be collected in the collecting container before it is necessary to empty the collecting container.
- the turbine, the filter and the filter cleaning unit can be particularly compact, i.e. with little free volume between the components, can be integrated in the proposed vacuum cleaner.
- the air flow i.e. The routing of the suction flow within the vacuum cleaner device can be optimized in the sense that the losses in pressure - for example at the time of filter cleaning - or in volume flow can be reduced considerably.
- the present invention is characterized by a compactness of the component arrangement through a relative arrangement of the components to one another.
- the motor is preferably set up to drive the turbine.
- the vacuum cleaner in this embodiment has a 15 degree inclined filter cartridge, which can advantageously be removed from the clean room side of the vacuum cleaner, although the filter cartridge is arranged below the motor or the turbine of the vacuum cleaner.
- the arrangement of an object below another object can mean in the context of the invention that the first object is arranged directly below the second object. In the context of the invention, however, it can also be preferred that the first object is arranged laterally offset from the second object, i.e. is present obliquely below the second object.
- the invention enables a simplified air flow through the preferred inclined motor position.
- a connection of the process air corridors can thus be achieved, which preferably relates to the filtration area, the negative pressure area, the guide area and / or the positive pressure area of the vacuum cleaner.

- the filter cleaning unit (9) preferably forms an upper right corner of the spanning triangle, with a right angle or an essentially right angle of the spanning triangle being present in this corner.

Insbesondere ist eine gezielte Verschachtelung der Saugerkomponenten innerhalb der Staubsaugvorrichtung vorgesehen, bei der insbesondere die genannten Saugerkomponenten in Bezug auf eine Horizontalebene schräg bzw. verkippt angeordnet vorliegen. In einem zweiten Aspekt betrifft die Erfindung eine Staubsaugvorrichtung, die über eine vorgeschlagene Anordnung von Komponenten verfügt, bei der einzelne Komponenten im Saugerkopf der Staubsaugvorrichtung ein Dreieck miteinander aufspannen.The present invention relates to an arrangement of components in a vacuum cleaning device, the vacuum cleaning device comprising at least one turbine and a filter as suction components. In particular, a specific nesting of the suction components within the vacuum cleaner is provided, in which in particular the mentioned suction components are arranged inclined or tilted with respect to a horizontal plane. In a second aspect, the invention relates to a vacuum cleaning device which has a proposed arrangement of components in which individual components in the suction head of the vacuum cleaning device form a triangle with one another.
Im Stand der Technik sind Staubsaugvorrichtungen bekannt, die insbesondere auf Baustellen genutzt werden, um in Verbindung mit der Benutzung von Werkzeugmaschinen, wie Bohr- oder Schleifgeräten, auftretenden Staub abzusaugen. Solche sogenannten Baustellensauger umfassen üblicherweise in einem oberen Bereich einen Saugerkopf und in einem unteren Bereich der Staubsaugvorrichtung einen Sammelbehälter für den aufgesaugten Staub. Solche Staubsauger werden im Sinne der Erfindung vorzugsweise auch als Industriesauger bezeichnet. Bei konventionellen Baustellensaugern, die aus dem Stand der Technik bekannt sind, liegen die Saugerkomponenten, wie Turbine, Motor, Filter, Filterabreinigungseinheit usw., im Wesentlichen vertikal und/oder horizontal innerhalb der Staubsaugvorrichtung angeordnet vor. Die Begriffe "horizontal" und "vertikal" sind dabei insbesondere auf die Seitenwände der Staubsaugvorrichtung bezogen, wobei die Begriffe "vertikale Anordnung" und "horizontale Anordnung" insbesondere bedeuten, dass die Saugerkomponenten im Wesentlichen parallel bzw. senkrecht in Bezug auf die Seitenwände der Staubsaugvorrichtung angeordnet sind. Durch diese vertikale und/oder horizontale Anordnung von Saugerkomponenten innerhalb der Staubsaugvorrichtung wird allerdings ggf. in unnötiger Weise freies Volumen in der Staubsaugvorrichtung geschaffen, weil durch starre Anordnungsvorgaben, die an den Seitenwänden der Staubsaugvorrichtung ausgerichtet sind, Freiräume innerhalb der Staubsaugvorrichtung entstehen können, die nicht optimal ausgenutzt werden. Dies stellt insbesondere dann einen Nachteil dar, wenn versucht werden soll, möglichst kompakte, handliche und leicht zu transportierende Sauger bereitzustellen.In the prior art, vacuum cleaning devices are known, which are used in particular on construction sites in order to suck off dust that occurs in connection with the use of machine tools such as drilling or grinding devices. Such so-called construction site vacuums usually comprise a suction head in an upper area and a collecting container for the vacuumed up dust in a lower area of the vacuum cleaner. Such vacuum cleaners are preferably also referred to as industrial vacuum cleaners in the context of the invention. In conventional construction site vacuum cleaners, which are known from the prior art, the suction components, such as turbine, motor, filter, filter cleaning unit, etc., are arranged essentially vertically and / or horizontally within the vacuum cleaner device. The terms "horizontal" and "vertical" are particularly related to the side walls of the vacuum cleaning device, the terms "vertical arrangement" and "horizontal arrangement" meaning in particular that the suction components are essentially parallel or perpendicular with respect to the side walls of the vacuum cleaning device are arranged. However, this vertical and / or horizontal arrangement of suction components within the vacuum cleaning device creates unnecessary free volume in the vacuum cleaning device, because rigid arrangement specifications that are aligned on the side walls of the vacuum cleaning device can create free spaces within the vacuum cleaning device that cannot can be optimally used. This is a disadvantage in particular when an attempt is made to provide suction cups that are as compact, handy and easy to transport as possible.
Darüber hinaus kann die starre Vertikal- bzw. Horizontalausrichtung von Saugerkomponenten dazu führen, dass einzelne Komponenten aufwändig miteinander verkabelt werden müssen, wenn sie nicht optimal zueinander innerhalb der Saugervorrichtung angeordnet vorliegen. Dies stellt einen ggf. unnötigen Ressourcenaufwand dar, der eine solche Staubsaugvorrichtung ggf. anfällig für Fehler macht oder zu einem erhöhten Reparatur- und/oder Wartungsaufwand führt. Darüber hinaus kann eine starre Vertikal- bzw. Horizontalanordnung von Saugerkomponenten zu einem erhöhten Dichtungsaufwand führen. Dies kann sich einerseits dadurch äußern, dass ein komplexes Dichtungskonzept angewendet werden muss. Es kann sich aber auch in einem erhöhten Materialaufwand äußern. Beide Effekte sind in Bezug auf eine Staubsaugvorrichtung unerwünscht, da sie zu erhöhtem Verschleiß bzw. Mehrgewicht und somit zu einer finanziellen Mehrbelastung bei Betrieb der Staubsaugvorrichtung führen können. Es hat sich ferner gezeigt, dass es bei konventionellen Staubsaugvorrichtungen, bei der die Saugerkomponenten in Bezug auf die Seitenwände vertikal und/oder horizontal ausgerichtet sind, zu vermehrten Leistungsverlusten kommt.In addition, the rigid vertical or horizontal alignment of suction components can lead to individual components having to be cabled to one another in a complex manner if they are not optimally arranged with respect to one another within the suction device. This represents a possibly unnecessary outlay on resources, which makes such a vacuum cleaner device possibly susceptible to errors or leads to increased repair and / or maintenance costs. In addition, a rigid vertical or horizontal arrangement of suction components can lead to increased sealing costs. On the one hand, this can manifest itself in the fact that a complex sealing concept must be used. However, it can also manifest itself in an increased cost of materials. Both effects are undesirable in relation to a vacuum cleaner device, since they can lead to increased wear and tear or additional weight and thus to an additional financial burden when operating the vacuum cleaner device. It has also been shown that conventional vacuum cleaning devices, in which the suction components are oriented vertically and / or horizontally with respect to the side walls, lead to increased performance losses.
Aufgabe der vorliegenden Erfindung ist es, die vorstehend beschriebenen Probleme zu lösen und eine Staubsaugvorrichtung bereitzustellen, in der die einzelnen Saugerkomponenten platzsparend zueinander angeordnet sind. Bei der bereitzustellenden Stausaugvorrichtung soll die Dichtung einfach und unkompliziert erfolgen können. Ferner soll ein in Bezug auf die Größe der Staubsaugvorrichtung leistungsstarker Sauger bereitgestellt werden, bei dem insbesondere eine einfache, aber effektive Luftführung möglich ist. Wünschenswert wäre es darüber hinaus, wenn der Filter bzw. eine Filtereinheit der bereitzustellenden Staubsaugvorrichtung an der Rückseite der Staubsaugvorrichtung entnommen werden könnte.The object of the present invention is to solve the problems described above and to provide a vacuum cleaning device in which the individual suction components are arranged relative to one another in a space-saving manner. In the case of the suction device to be provided, the seal should be simple and uncomplicated. Furthermore, a vacuum cleaner that is powerful in relation to the size of the vacuum cleaner device is to be provided, in which, in particular, simple but effective air guidance is possible. It would also be desirable if the filter or a filter unit of the vacuum cleaner to be provided could be removed from the rear of the vacuum cleaner.

Vorteilhafte Ausführungsformen zu dem Gegenstand der unabhängigen Ansprüche finden sich in den abhängigen Unteransprüchen.The object is achieved by the subject matter of the independent claims. Advantageous embodiments relating to the subject matter of the independent claims can be found in the dependent subclaims.
Die Aufgabe wird hierbei gelöst durch eine Anordnung von Komponenten in einer Staubsaugvorrichtung, wobei die Staubsaugvorrichtung in einem Saugerkopf mindestens eine Turbine, einen Filter und eine Filterabreinigungseinheit umfasst. Die Anordnung ist dadurch gekennzeichnet, dass die Turbine, der Filter und die Filterabreinigungseinheit in dem Saugerkopf ein Dreieck aufspannen. Das Dreieck ergibt sich insbesondere in einer Seitenansicht des Saugerkopfes der Staubsaugvorrichtung. Vorzugsweise bilden die drei genannten Saugerkomponenten die Eckpunkte des Dreiecks. Dabei bilden die Turbine und die Filterabreinigungseinheit vorzugsweise eine im Wesentlichen horizontale obere Kante des Dreiecks, wobei die Turbine in einem vorderen Bereich des Saugerkopfes der Staubsaugvorrichtung angeordnet vorliegt und die Filterabreinungseinheit in einem hinteren Bereich. Vorzugsweise ist das sich bildende Dreieck ein im Wesentlichen rechtwinkliges Dreieck, dessen rechter Winkel im Bereich der Filterabreinigungseinrichtung vorliegt. Die horizontale obere Kante des Dreiecks, die vorzugsweise zwischen Turbine und Filterabreinigungseinheit angeordnet ist, stellt vorzugsweise einer der beiden Katheten des im Wesentlichen rechtwinkligen Dreiecks dar. Die zweite Kathete des im Wesentlichen rechtwinkligen Dreiecks liegt vorzugsweise zwischen der Filterabreinigungseinheit und dem Filter angeordnet vor, während die Hypothenuse zwischen einem geometrischen Schwerpunkt des Filters und einem geometrischen Schwerpunkt der Turbine vorliegt. Das Dreieck zwischen den Saugerkomponenten wird insbesondere dadurch aufgespannt, dass die Turbine im Wesentlichen neben der Filterabreinigungseinheit angeordnet vorliegt, der Filter im Wesentlichen unterhalb der Filterabreinigungseinheit angeordnet vorliegt und die Turbine im Wesentlichen schräg oberhalb dem Filter angeordnet vorliegt. Durch die Anordnung der Saugerkomponenten in einem Dreieck wendet sich die Erfindung vom Stand der Technik ab. Bei konventionellen Staubsaugvorrichtungen, die aus dem Stand der Technik bekannt sind, liegen die genannten Komponenten häufig in einem Viereck-Arrangement vor.The object is achieved by an arrangement of components in a vacuum cleaner, the vacuum cleaner comprising at least one turbine, a filter and a filter cleaning unit in a suction head. The arrangement is characterized in that the turbine, the filter and the filter cleaning unit in the suction head form a triangle. The triangle results in particular in a side view of the suction head of the vacuum cleaning device. The three mentioned teat components preferably form the corner points of the triangle. The turbine and the filter cleaning unit preferably form an essentially horizontal upper edge of the triangle, with the turbine in a front Area of the suction head of the vacuum cleaning device is arranged and the filter cleaning unit in a rear area. The triangle that forms is preferably an essentially right-angled triangle, the right angle of which is in the area of the filter cleaning device. The horizontal upper edge of the triangle, which is preferably arranged between the turbine and the filter cleaning unit, preferably represents one of the two legs of the essentially right-angled triangle. The second leg of the essentially right-angled triangle is preferably arranged between the filter cleaning unit and the filter, while the Hypotenuse is present between a geometric center of gravity of the filter and a geometric center of gravity of the turbine. The triangle between the suction components is spanned in particular in that the turbine is arranged essentially next to the filter cleaning unit, the filter is arranged essentially below the filter cleaning unit and the turbine is arranged essentially obliquely above the filter. By arranging the nipple components in a triangle, the invention turns away from the prior art. In conventional vacuum cleaning devices, which are known from the prior art, the components mentioned are often present in a square arrangement.
Insbesondere liegen bei der vorgeschlagenen Komponentenanordnung die einzelnen Komponenten verkippt zu einer horizontalen und/oder vertikalen Achse des Saugerkopfes der Staubsaugvorrichtung vor. In einer Ausführungsform der Erfindung ist es bevorzugt, dass eine gedachte erste zentrale Achse durch den Filter der Staubsaugvorrichtung mit einer gedachten Horizontalebene einen ersten Winkel zwischen 10 bis 20 Grad bildet und eine gedachte zweite zentrale Achse durch die Turbine der Staubsaugvorrichtung mit einer gedachten Horizontalebene einen zweiten Winkel zwischen 145 bis 155 Grad bildet. Die genannten Winkelgrößen ermöglichen vorzugsweise die dreieckförmige Anordnung der Saugerkomponenten Turbine, Filterabreinigungseinheit und Filter.In particular, in the proposed component arrangement, the individual components are tilted to a horizontal and / or vertical axis of the suction head of the vacuum cleaner device. In one embodiment of the invention, it is preferred that an imaginary first central axis through the filter of the vacuum cleaner with an imaginary horizontal plane forms a first angle between 10 to 20 degrees and an imaginary second central axis through the turbine of the vacuum cleaner with an imaginary horizontal plane forms a second Forms angles between 145 to 155 degrees. The aforementioned angular sizes preferably enable the triangular arrangement of the suction components turbine, filter cleaning unit and filter.
Die dreieckförmige Anordnung der Saugerkomponenten im Saugerkopf der Staubsaugvorrichtung ermöglicht vorzugsweise eine kompakte Bauweise für die Staubsaugvorrichtung, bei der durch eine gezielte Verschachtelung einzelner Saugerkomponenten eine Reihe von Vorteilen erreicht werden. Zum einen kann mit der kompakten Anordnung der Saugerkomponenten, insbesondere des Filters und der Turbine, die Anzahl der in der Staubsaugvorrichtung zu verbauenden Teile reduziert werden. Dies kann vorteilhafterweise dadurch erreicht werden, dass eine Grundplatte des Saugerkopfes eine zentrale Stelle bildet, an der die Saugerkomponenten angeordnet werden können. Die Schrägstellung der Komponenten in den oben genannten Winkelbereichen, die vorteilhafterweise zu der dreieckförmigen Anordnung der Saugerkomponenten führt, ermöglicht vorzugsweise die vorteilhafte, platzsparende Verschachtelung der Komponenten und das Aneinanderrücken der Komponenten im Saugerkopf.The triangular arrangement of the suction components in the suction head of the vacuum cleaning device preferably enables a compact design for the vacuum cleaning device, in which a number of advantages can be achieved through a targeted nesting of individual suction components. On the one hand, with the compact arrangement of the suction components, in particular the filter and the turbine, the number of parts to be installed in the vacuum cleaning device can be reduced. This can advantageously be achieved in that a base plate of the suction head forms a central point at which the suction components can be arranged. The inclination of the components in the above-mentioned angular ranges, which advantageously leads to the triangular arrangement of the suction components, preferably enables the advantageous, space-saving nesting of the components and the moving of the components together in the suction head.
Dadurch kann die vorgeschlagene Staubsaugvorrichtung einfach konstruiert und hergestellt werden und ist vorteilhafterweise besonders wartungsarm. Darüber hinaus kann die Effizienz der Staubsaugvorrichtung erheblich erhöht werden, weil die Staubsaugvorrichtung besonders kompakt und platzsparend ausgeführt werden kann. Dadurch wird auch ihre Handhabung bzw. ihr Gebrauch erleichtert. Durch die gezielte Verkippung bzw. Schräganordnung von Saugerkomponenten, wie Turbine oder Filter, kann vorteilhafterweise das zur Verfügung stehende nutzbare Behältervolumen vergrößert werden, so dass mit der vorgeschlagenen Staubsaugvorrichtung eine größere Menge Staub aufgenommen und gesammelt werden kann. Ein besonderer Vorteil der vorgeschlagenen Komponentenanordnung für eine Staubsaugvorrichtung besteht darin, dass der Filter der Staubsaugvorrichtung an der Rückseite der Staubsaugvorrichtung entnommen bzw. ausgewechselt werden kann. Dadurch wird eine optimierte Luftführung innerhalb der Staubsaugvorrichtung ermöglicht. Insbesondere können durch die verbesserte Luftführung innerhalb der Staubsaugvorrichtung die Volumenstrom- und Druckverluste wesentlich reduziert werden.As a result, the proposed vacuum cleaning device can be designed and manufactured in a simple manner and is advantageously particularly low-maintenance. In addition, the efficiency of the vacuum cleaner can be increased considerably because the vacuum cleaner can be designed to be particularly compact and space-saving. This also facilitates their handling or use. The targeted tilting or inclined arrangement of suction components such as turbines or filters can advantageously increase the available usable container volume so that a larger amount of dust can be picked up and collected with the proposed vacuum cleaner. A particular advantage of the proposed component arrangement for a vacuum cleaning device is that the filter of the vacuum cleaning device can be removed or replaced on the rear of the vacuum cleaning device. This enables an optimized air flow within the vacuum cleaner. In particular, the volume flow and pressure losses can be significantly reduced due to the improved air routing within the vacuum cleaner.
Im Kontext der vorgeschlagenen Komponentenanordnung ist es bevorzugt, dass der Filter und die Turbine in Bezug auf eine Horizontalebene verkippt angeordnet sind. Mit anderen Worten liegen die genannten Saugerkomponenten schräg innerhalb des Saugerkopfes der Staubsaugvorrichtung vor. Die Schrägstellung der einzelnen Saugerkomponenten wird durch einen Neigungswinkel definiert, der von einer gedachten zentralen Achse durch die Saugerkomponente und eine gedachten Horizontalebene gebildet wird. Die gedachte zentrale Achse durch den Filter wird im Sinne der Erfindung als erste gedachte zentrale Achse der Staubsaugvorrichtung bezeichnet, während die gedachte zentrale Achse durch die Turbine als zweite gedachte zentrale Achse der Staubsaugvorrichtung bezeichnet wird. Entsprechend wird der Neigungswinkel des Filters als erster Winkel bezeichnet. Dieser erste Winkel liegt vorzugsweise in einem Bereich zwischen 10 bis 20 Grad, wobei insbesondere Neigungswinkelwerte zwischen 13 und 17 Grad und besonders bevorzugt von 15 Grad für den Filter bevorzugt sind. Mit anderen Worten ist es bevorzugt, dass der erste Winkel zwischen 13 und 17 Grad und besonders bevorzugt bei 15 Grad liegt. Der entsprechende erste Winkel ist in der
Die Größe des Neigungswinkels wird im Sinne der Erfindung bevorzugt entsprechend der mathematischen Sichtweise dadurch ermittelt, dass die Horizontalebene als positive x-Achse eines kartesischen Koordinatensystems betrachtet wird und die Achse durch den Filter bzw. durch die Turbine als Schenkel oder Zeiger, wobei der eingeschlossene Winkel zwischen x-Achse und Schenkel vorzugsweise dem Neigungswinkel für die jeweilige Komponente entspricht. Der Fachmann erkennt, dass der die erste gedachte zentrale Achse, die bevorzugt mittig durch den Filter verläuft, im ersten Quadranten eines solchen kartesischen Koordinatensystems liegt, während die zweite gedachte zentrale Achse, die bevorzugt mittig durch die Turbine verläuft, im zweiten Quadranten eines solchen kartesischen Koordinatensystems liegt.According to the invention, the size of the angle of inclination is preferably determined according to the mathematical point of view in that the horizontal plane is viewed as the positive x-axis of a Cartesian coordinate system and the axis through the filter or the turbine as a limb or pointer, with the included angle between the x-axis and the leg preferably corresponds to the angle of inclination for the respective component. The person skilled in the art recognizes that the first imaginary central axis, which preferably runs centrally through the filter, lies in the first quadrant of such a Cartesian coordinate system, while the second imaginary central axis, which preferably runs centrally through the turbine, lies in the second quadrant of such a Cartesian coordinate system Coordinate system.
Der Neigungswinkel der Turbine wird im Sinne der Erfindung als zweiter Winkel bezeichnet. Dieser liegt vorzugsweise in einem Bereich zwischen 145 bis 155 Grad, wobei insbesondere Neigungswinkelwerte zwischen 148 und 152 Grad und besonders bevorzugt bei 150 Grad für den Filter bevorzugt sind. Mit anderen Worten ist es bevorzugt, dass der zweite Winkel zwischen 148 und 152 Grad und besonders bevorzugt bei 150 Grad liegt. Verlängert man die oben beschriebene x-Achse über die y-Achse des Koordinatensystems in den zweiten Quadranten hinaus und verwendet diese "negative x-Achse" als Ausgangspunkt für die Festlegung der Größe des zweiten Neigungswinkels für die Turbine, ergibt sich ein zweiter Neigungswinkel in einem Bereich von 25 bis 35 Grad, bevorzugt 28 bis 32 Grad und besonders bevorzugt von 30 Grad. Im Sinne der Erfindung können alle Werte zwischen 145 und 155 Grad bevorzugt sein, insbesondere die Werte 145, 146, 147, 148, 149, 150, 151, 152, 153, 154, 155 und alle rationalen und nicht-rationalen Zwischenwerte. Ferner können auch Werte zwischen 140 und 160 Grad bevorzugt sein, als insbesondere 140, 141, 142, 143, 144 oder 156, 157, 158, 159 oder 160, sowie alle rationalen und nicht-rationalen Zwischenwerte. Dieser zweite Winkel, der von der negativen x-Achse und der Zentralachse durch die Turbine festgelegt wird, ist ebenfalls in der Figur 1 angedeutet.The angle of inclination of the turbine is referred to as the second angle in the context of the invention. This is preferably in a range between 145 to 155 degrees, with inclination angle values between 148 and 152 degrees and particularly preferably 150 degrees being preferred for the filter. In other words, it is preferred that the second angle is between 148 and 152 degrees and particularly preferably 150 degrees. If the above-described x-axis is extended beyond the y-axis of the coordinate system into the second quadrant and this "negative x-axis" is used as the starting point for determining the size of the second angle of inclination for the turbine, a second angle of inclination results in one Range from 25 to 35 degrees, preferably 28 to 32 degrees and particularly preferably from 30 degrees. For the purposes of the invention, all values between 145 and 155 degrees can be preferred, in particular the values 145, 146, 147, 148, 149, 150, 151, 152, 153, 154, 155 and all rational and non-rational intermediate values. Furthermore, values between 140 and 160 degrees can also be preferred, in particular 140, 141, 142, 143, 144 or 156, 157, 158, 159 or 160, as well as all rational and non-rational intermediate values. This second angle, which is defined by the negative x-axis and the central axis through the turbine, is also indicated in FIG.
Somit sind die Saugerkomponenten Filter und Turbine gerade nicht horizontal oder vertikal in Bezug auf Seitenwände des Saugerkopfes der Staubsaugvorrichtung ausgerichtet, sondern die genannten Saugerkomponenten nehmen eine Schrägstellung in Bezug auf die Außenwände der Staubsaugvorrichtung ein, indem sie gegenüber der gedachten Horizontalebene verkippt ausgebildet sind.Thus, the suction components filter and turbine are not aligned horizontally or vertically with respect to the side walls of the suction head of the vacuum cleaning device, but the mentioned suction components assume an inclined position with respect to the outer walls of the vacuum cleaning device by being tilted relative to the imaginary horizontal plane.
Die Begriffe "horizontal" und "vertikal" beziehen sich im Kontext der vorliegenden Erfindung bevorzugt auf die zumeist im Wesentlichen senkrecht zum Erdboden ausgerichteten Seitenwände der Staubsaugvorrichtung, wobei der Begriff "horizontal" im Sinne der Erfindung bevorzugt bedeutet, dass ein Gegenstand im Wesentlichen parallel zum Erdboden bzw. im Wesentlichen senkrecht zu einer Seitenwand des Staubsaugers angeordnet ist, während der Begriff "vertikal" im Sinne der Erfindung bevorzugt bedeutet, dass ein Gegenstand im Wesentlichen senkrecht zum Erdboden bzw. im Wesentlichen parallel zu einer Seitenwand des Staubsaugers angeordnet vorliegt. Eine Horizontalebene, die gedanklich durch den Staubsauger gelegt werden kann, ist somit eine gedachte Ebene, die im Wesentlichen parallel zur Erdoberfläche verläuft. Das bedeutet im Sinne der Erfindung bevorzugt, dass eine Gerade, die in der gedachten Horizontalebene verläuft, mit der Erdoberfläche einen Winkel von ca. 0 Grad einschließt. Minimale Abweichungen von der Erdoberfläche in einem Bereich von 0 bis 5 Grad werden im Sinne der Erfindung vorzugsweise von dem Begriff "horizontal" erfasst, da es zu Messungenauigkeiten kommen kann bzw. weil die Erdoberfläche nicht immer vollkommen plan ausgebildet ist. Es ist im Sinne der Erfindung bevorzugt, von einer idealisierten, im Wesentlichen planen Erdoberfläche auszugehen.In the context of the present invention, the terms “horizontal” and “vertical” preferably relate to the side walls which are mostly oriented essentially perpendicular to the ground the vacuum cleaner, where the term "horizontal" in the context of the invention preferably means that an object is arranged essentially parallel to the ground or essentially perpendicular to a side wall of the vacuum cleaner, while the term "vertical" in the context of the invention preferably means that an object is arranged essentially perpendicular to the ground or essentially parallel to a side wall of the vacuum cleaner. A horizontal plane that can be imagined through the vacuum cleaner is thus an imaginary plane that runs essentially parallel to the earth's surface. In the context of the invention, this means that a straight line running in the imaginary horizontal plane encloses an angle of approximately 0 degrees with the surface of the earth. Minimal deviations from the earth's surface in a range of 0 to 5 degrees are preferably covered by the term "horizontal" within the meaning of the invention, since measurement inaccuracies can occur or because the earth's surface is not always completely flat. In the context of the invention, it is preferred to start from an idealized, essentially planar surface of the earth.
Eine verkippte oder schräge Anordnung einer Saugerkomponente in Bezug auf eine solche virtuelle Horizontalebene bedeutet im Sinne der Erfindung bevorzugt, dass eine Achse, die vorzugsweise als gedachte Zentralachse durch die schräge oder verkippte Saugerkomponente verläuft, mit der Horizontalebene einen Winkel einschließt, der wesentlich größer als 0 ist. Dieser Winkel wird im Sinne der Erfindung als "Neigungswinkel" der entsprechenden Saugerkomponente bezeichnet. Insbesondere ist die Erfindung somit durch eine Schrägstellung der Saugerkomponenten Turbine und Filter gekennzeichnet.A tilted or inclined arrangement of a teat component in relation to such a virtual horizontal plane preferably means in the context of the invention that an axis, which preferably runs as an imaginary central axis through the inclined or tilted teat component, encloses an angle with the horizontal plane that is significantly greater than 0 is. In the context of the invention, this angle is referred to as the "angle of inclination" of the corresponding suction component. In particular, the invention is thus characterized by an inclined position of the suction components turbine and filter.
Die Turbine der Staubsaugvorrichtung ist vorzugsweise dazu eingerichtet, durch Erzeugung eines Luftstroms den Absaugstrom für den - beispieslweise auf einer Baustelle anfallenden - Staub zu erzeugen. Insbesondere wird in der Staubsaugvorrichtung ein Unterdruck erzeugt, mit dem der Absaugstrom zur Absaugung des Staubes bereitgestellt werden kann.The turbine of the vacuum cleaner is preferably set up to generate the suction flow for the dust - for example on a construction site - by generating an air flow. In particular, a negative pressure is generated in the vacuum cleaner, with which the suction flow can be provided for suctioning off the dust.
Die Staubsaugvorrichtung kann neben dem Filter, der im Kontext der vorliegenden Erfindung eine Schrägstellung in Bezug auf eine Horizontale von 10 bis 20 Grad aufweist, weitere Filter- oder Filterelemente aufweisen. Der verkippte Filter kann im Sinne der Erfindung auch als Filterkassette oder als Hauptfilter bezeichnet werden, wobei die Filterkassette durch die vorgeschlagene kompakte Bauweise vorteilhafterweise nunmehr von hinten aus der vorgeschlagenen Staubsaugvorrichtung entnommen werden kann. Die Begriffe "Vorderseite" und "Hinterseite" oder "Rückseite" sind für den Fachmann in Bezug auf eine Staubsaugvorrichtung keine unklaren Begriffe, weil der Fachmann an der Gestaltung und an der Anordnung der Komponenten der Staubsaugvorrichtung erkennen kann, welches die Vorderseite und welches die Rückseite der Staubsaugvorrichtung ist. Beispielsweise kann an der Vorderseite ein Bediendisplay mit Knöpfen und Bedienelemente vorgesehen sein.In addition to the filter, which in the context of the present invention has an inclination with respect to a horizontal of 10 to 20 degrees, the vacuum cleaning device can have further filter or filter elements. In the context of the invention, the tilted filter can also be referred to as a filter cassette or as a main filter, the filter cassette advantageously now being able to be removed from the proposed vacuum cleaner device from behind due to the proposed compact design. The terms "front" and "rear" or "rear" are not unclear terms for the person skilled in the art in relation to a vacuum cleaning device, because the person skilled in the art is familiar with the design and arrangement of the components of the Vacuum cleaner can recognize which is the front and which is the back of the vacuum cleaner. For example, a control display with buttons and control elements can be provided on the front.
Bei Betrieb der Staubsaugvorrichtung können sich die Filter mit Staub zusetzen. Die vorgeschlagene Staubsaugvorrichtung kann daher eine Filterabreinigungseinheit umfassen, mit der manuell oder automatisch eine Abreinigung des Filters bzw. der Filterelemente der Staubsaugvorrichtung bewirkt werden kann. Es ist im Sinne der Erfindung bevorzugt, dass die Turbine der vorgeschlagenen Staubsaugvorrichtung neben dieser Filterabreinigungseinheit angeordnet vorliegt und dass der Filter unterhalb dieser Filterabreinigungseinheit angeordnet vorliegt. Die Erfinder haben erkannt, dass diese Anordnung besonders vorteilhaft ist, weil sie eine effiziente Abreinigung des Filters durch eine optimierte Ausrichtung der Abreinigungseinheit relativ zum Filter ermöglicht.When the vacuum cleaner is in operation, the filters can become clogged with dust. The proposed vacuum cleaner can therefore include a filter cleaning unit with which the filter or the filter elements of the vacuum cleaner can be cleaned manually or automatically. In the context of the invention, it is preferred that the turbine of the proposed vacuum cleaner is arranged next to this filter cleaning unit and that the filter is arranged below this filter cleaning unit. The inventors have recognized that this arrangement is particularly advantageous because it enables efficient cleaning of the filter through an optimized alignment of the cleaning unit relative to the filter.
Es ist im Sinne der Erfindung bevorzugt, dass sich die Filterabreinigungseinheit direkt über dem Filter befindet, der in einer besonders bevorzugten Ausgestaltung der Erfindung um 15 Grad in Bezug auf eine Horizontalebene der Staubsaugvorrichtung verkippt ist. Insbesondere durch diese Verkippung wird das für die Aufnahme von Staub zur Verfügung stehende Behältervolumen erheblich vergrößert, so dass vorteilhaftweise mehr Staubs in dem Sammelbehälter gesammelt werden kann, bevor eine Leerung des Sammelbehälters erforderlich ist. Durch die Vergrößerung der Zeitabstände zwischen den erforderlichen Leerungen können die Arbeiter auf einer Baustelle anderen Tätigkeiten nachgehen, so dass durch die Erfindung Bauzeiten verkürzt werden und eine effektive Beschäftigung der Mitarbeiter auf Baustellen ermöglicht wird.For the purposes of the invention, it is preferred that the filter cleaning unit is located directly above the filter, which in a particularly preferred embodiment of the invention is tilted by 15 degrees with respect to a horizontal plane of the vacuum cleaner device. This tilting, in particular, significantly increases the container volume available for receiving dust, so that advantageously more dust can be collected in the collecting container before it is necessary to empty the collecting container. By increasing the time intervals between the required emptying, the workers on a construction site can pursue other activities, so that construction times are shortened by the invention and an effective employment of the employees on construction sites is made possible.
Durch die darüber hinaus bevorzugte Schrägstellung der Turbine um 30 bzw. 150 Grad können die Turbine, der Filter und die Filterabreinigungseinheit besonders kompakt, d.h. mit wenig freien Volumen zwischen den Bauteilen, in der vorgeschlagenen Staubsaugvorrichtung integriert werden. Insbesondere kann dadurch auch die Luftführung, d.h. die Führung des Absaugstroms innerhalb der Staubsaugvorrichtung in dem Sinnen optimiert werden, dass die Verluste an Druck - zum Beispiel zum Zeitpunkt der Filterabreinigung - oder an Volumenstrom erheblich reduziert werden können.Due to the further preferred inclination of the turbine by 30 or 150 degrees, the turbine, the filter and the filter cleaning unit can be particularly compact, i.e. with little free volume between the components, can be integrated in the proposed vacuum cleaner. In particular, the air flow, i.e. The routing of the suction flow within the vacuum cleaner device can be optimized in the sense that the losses in pressure - for example at the time of filter cleaning - or in volume flow can be reduced considerably.
Die vorliegende Erfindung ist in einem besonders bevorzugten Ausführungsbeispiel der Erfindung durch eine Kompaktheit der Komponentenanordnung durch eine relative Anordnung der Komponenten zueinander gekennzeichnet.In a particularly preferred exemplary embodiment of the invention, the present invention is characterized by a compactness of the component arrangement through a relative arrangement of the components to one another.
Der Motor ist vorzugsweise dazu eingerichtet, die Turbine anzutreiben. Darüber hinaus weist die Staubsaugvorrichtung in diesem Ausführungsbeispiel eine um 15 Grad schräg stehende Filterkassette auf, die vorteilhafterweise auf der Reinraumseite der Staubsaugvorrichtung entnommen werden kann, obwohl die Filterkassette unterhalb des Motors bzw. der Turbine der Staubsaugvorrichtung angeordnet ist. Die Anordnung eines Gegenstands unterhalb eines anderen Gegenstands kann im Sinne der Erfindung bedeuten, dass der erste Gegenstand direkt unterhalb des zweiten Gegenstand angeordnet vorliegt. Es kann aber im Sinne der Erfindung auch bevorzugt sein, dass der erste Gegenstand seitlich versetzt zum zweiten Gegenstand angeordnet ist, d.h. schräg unterhalb des zweiten Gegenstands vorliegt. Insbesondere ermöglicht die Erfindung eine vereinfachte Luftführung durch die bevorzugte schräge Motorposition. Insbesondere kann damit eine Verbindung der Prozessluftkorridore erreicht werden, die vorzugsweise den Filtrationsbereich, den Unterdruckbereich, den Führungsbereich und/oder den Überdruckbereich der Staubsaugvorrichtung betrifft.The motor is preferably set up to drive the turbine. In addition, the vacuum cleaner in this embodiment has a 15 degree inclined filter cartridge, which can advantageously be removed from the clean room side of the vacuum cleaner, although the filter cartridge is arranged below the motor or the turbine of the vacuum cleaner. The arrangement of an object below another object can mean in the context of the invention that the first object is arranged directly below the second object. In the context of the invention, however, it can also be preferred that the first object is arranged laterally offset from the second object, i.e. is present obliquely below the second object. In particular, the invention enables a simplified air flow through the preferred inclined motor position. In particular, a connection of the process air corridors can thus be achieved, which preferably relates to the filtration area, the negative pressure area, the guide area and / or the positive pressure area of the vacuum cleaner.

Die Definitionen, technischen Wirkungen und Vorteile der Erfindung, die für die Komponentenanordnung beschrieben wurden, gelten für die vorgeschlagene Staubsaugvorrichtung analog.In a further aspect, the invention relates to a vacuum cleaner device, the vacuum cleaner device having an arrangement of components according to one or more of the preceding claims.
