Description

Reinigungsgerät Cleaning device
Die Erfindung betrifft ein Reinigungsgerät, umfassend einen Grundkörper, welchem auf der dem zu reinigenden Boden zugewandten Unterseite zumindest ein Reinigungskörper zugeordnet ist, wobei der Reinigungskörper um eine Rotations achse rotierbar an dem Grundkörper gelagert ist, wobei die Rotationsachse des Reinigungskörpers senkrecht zu der Unterseite des Grundkörpers ausgerichtet ist. The invention relates to a cleaning device, comprising a base body to which at least one cleaning body is assigned on the underside facing the floor to be cleaned, the cleaning body being rotatably mounted on the base body about an axis of rotation, the axis of rotation of the cleaning body being perpendicular to the underside of the base body is aligned.
Neben den Reinigungskörpern weist der Grundkörper vorteilhafterweise noch eine Einrichtung auf, mittels derer der Grundkörper über den zu reinigenden Boden ver fahrbar ist. Die Einrichtung kann dabei Walzen oder Rollen umfassen. Des Weiteren können die Walzen oder Rollen auch elektromotorisch antreibbar sein. Des Weiteren kann an dem Grundkörper ein Stiel mit einem Handgriff befestigt sein. Alternativ kann das Reinigungsgerät für eine autonome Reinigung sein. In addition to the cleaning bodies, the base body advantageously also has a device by means of which the base body can be moved over the floor to be cleaned. The device can include rollers or rollers. Furthermore, the rollers or rollers can also be driven by an electric motor. Furthermore, a handle can be attached to the base body with a handle. Alternatively, the cleaning device can be for autonomous cleaning.
Stand der Technik State of the art
Aus dem Stand der Technik sind Reinigungsgeräte bekannt, bei welchen Reinigungskörper rotierbar an der Unterseite des Grundkörpers gelagert sind, wobei die Rotationsachse senkrecht zu der Unterseite ausgerichtet ist. Die Reinigungs körper sind dabei zumeist den vorderen Ecken des Grundkörpers zugeordnet. Aufgrund der rotierbaren Lagerung der Reinigungskörper sind die Reinigungsflächen der Reinigungskörper zumeist rotationssymmetrisch, also kreisförmig, ausgebildet. Durch diese Ausgestaltung ergibt sich die Problematik, dass Ecken der zu reinigen den Böden von den Reinigungskörpern nicht erreicht werden können, so dass sich dort Schmutz ansammeln kann. Aufgabenstellung Cleaning devices are known from the prior art in which cleaning bodies are rotatably mounted on the underside of the base body, the axis of rotation being oriented perpendicular to the underside. The cleaning bodies are mostly assigned to the front corners of the base body. Due to the rotatable mounting of the cleaning bodies, the cleaning surfaces of the cleaning bodies are mostly designed to be rotationally symmetrical, that is to say circular. This configuration results in the problem that corners of the floors to be cleaned cannot be reached by the cleaning bodies, so that dirt can collect there. Task
Der Erfindung liegt die Aufgabe zugrunde, ein Reinigungsgerät der eingangs genannten Art derart weiterzuentwickeln, dass das Reinigungsgerät eine verbesserte Reinigungswirkung aufweist. The invention is based on the object of further developing a cleaning device of the type mentioned at the beginning in such a way that the cleaning device has an improved cleaning effect.
Diese Aufgabe wird mit den Merkmalen von Anspruch 1 gelöst. Auf vorteilhafte Aus gestaltungen nehmen die Unteransprüche Bezug. This object is achieved with the features of claim 1. The subclaims refer to advantageous configurations.
Technische Lösung Technical solution
Zur Lösung der Aufgabe ist der Reinigungskörper derart in dem Grundkörper gelagert, dass die Rotationsachse während der Reinigungsarbeit relativ zu der Unterseite entlang einer senkrecht zur Rotationsachse ausgerichteten Bewegungs bahn bewegbar ist. In anderen Worten: die Rotationsachse des Reinigungskörpers wird während der Reinigungsarbeit relativ zum Grundkörper bewegt. To achieve the object, the cleaning body is mounted in the base body in such a way that the axis of rotation can be moved relative to the underside during the cleaning work along a movement path oriented perpendicular to the axis of rotation. In other words: the axis of rotation of the cleaning body is moved relative to the base body during the cleaning work.
Insofern ist bei dem erfindungsgemäßen Reinigungsgerät der Reinigungskörper so in dem Grundkörper gelagert, dass dieser keine feste, d.h. relativ zum Grundkörper ortsfeste Rotationsachse hat. Dadurch kann der Reinigungskörper derart rotieren, dass Eckbereiche besser erreichbar sind. To this extent, in the cleaning device according to the invention, the cleaning body is mounted in the base body in such a way that it does not have a fixed axis of rotation, i.e. a fixed axis of rotation relative to the base body. As a result, the cleaning body can rotate in such a way that corner areas can be reached more easily.
Vorzugsweise bewegt sich die Rotationsachse entlang einer Kreisbahn. Dabei taumelt der Reinigungskörper mit seiner Rotationsachse entlang der Kreisbahn, wobei der Reinigungskörper relativ zu dem zu reinigenden Boden neben einer Rotationsbewegung auch eine überlagerte seitliche Bewegung ausführt. Durch die Überlagerung einer Rotations- mit einer Seitwärtsbewegung verbessert sich das Reinigungsergebnis. Zusätzlich kann noch eine Bewegung des Reinigungsgeräts überlagert sein, z.B. durch Verschieben oder Verfahren des Reinigungsgeräts auf der zu reinigenden Fläche. The axis of rotation preferably moves along a circular path. The cleaning body wobbles with its axis of rotation along the circular path, the cleaning body also executing a superimposed lateral movement relative to the floor to be cleaned in addition to a rotational movement. The superimposition of a rotation and a sideways movement improves the cleaning result. In addition, a movement of the cleaning device can be superimposed, e.g. by moving or moving the cleaning device on the surface to be cleaned.
Der Reinigungskörper kann mit einem Reinigungspad versehen sein, wobei das Reinigungspad eine Reinigungsfläche aufweist, welche eine von der Kreisform abweichende Gestalt aufweist. In diesem Zusammenhang ist denkbar, dass die Reinigungsfläche in zumindest einem Bereich einen kleineren Radius aufweist, als der die Reinigungsfläche begrenzendes Umfangskreis. Des Weiteren kann die Reinigungsfläche in einem Bereich zugespitzt sein. Bei diesen Ausgestaltungen ist die Reinigungsfläche im Wesentlichen kreisförmig, weicht aber in zumindest einem Bereich von der Kreisform ab. Schließlich kann die Reinigungsfläche auch eine poly gonale Form aufweisen. Im Zusammenhang mit der variablen Rotationsachse kann die Gestalt der Reinigungsfläche dabei so gewählt werden, dass sich ein verbesser tes Reinigungsergebnis, insbesondere in Ecken ergibt. The cleaning body can be provided with a cleaning pad, the cleaning pad having a cleaning surface which is circular in shape has a different shape. In this context, it is conceivable that the cleaning surface has a smaller radius in at least one area than the circumferential circle delimiting the cleaning surface. Furthermore, the cleaning surface can be pointed in one area. In these configurations, the cleaning surface is essentially circular, but deviates from the circular shape in at least one area. Finally, the cleaning surface can also have a polygonal shape. In connection with the variable axis of rotation, the shape of the cleaning surface can be selected in such a way that the cleaning result is improved, especially in corners.
Gemäß einer vorteilhaften Ausgestaltung ist die Reinigungsfläche als polygonales Gleichdick ausgebildet ist. Ist die Reinigungsfläche als polygonales Gleichdick aus gebildet, sind die einander gegenüberliegenden Kanten des Reinigungspads an jeder Stelle gleich weit voneinander entfernt. Insofern bildet der umlaufende Rand des Reinigungspads eine Kurve konstanter Breite. Aufgrund der polygonalen Ausgestal tung weicht die Reinigungsfläche aber von der Kreisform ab. Durch die Ausgestal tung als Gleichdick ist das Reinigungspad besonders für die Reinigung von schwierig erreichbaren Eckbereichen geeignet. According to an advantageous embodiment, the cleaning surface is designed as a polygonal uniform thickness. If the cleaning surface is designed as a polygonal uniform thickness, the opposing edges of the cleaning pad are equidistant from one another at every point. In this respect, the circumferential edge of the cleaning pad forms a curve of constant width. Due to the polygonal design, the cleaning surface deviates from the circular shape. Due to the design as a uniform thickness, the cleaning pad is particularly suitable for cleaning corner areas that are difficult to reach.
In einer vorteilhaften Ausgestaltung ist die Reinigungsfläche des Reinigungspads als Reuleaux-Dreieck ausgebildet. Ein Reuleaux-Dreieck ist ein Gleichdick, bei welchem der Abstand jedes Punktes einer Seite vom gegenüberliegenden Eckpunkt konstant ist. Die konstante Breite bleibt beim Drehen um den Flächenmittelpunkt erhalten. In Kombination mit der variablen Rotationsachse ergibt sich ein verbessertes Reinigungsergebnis. Insbesondere wenn sich die Rotationsachse entlang einer Kreisbahn bewegt, kann die kreisförmige Bewegung der Rotationsachse und die Bewegung des Reinigungspads derart abgestimmt werden, dass die Spitzen des dreieckförmigen Reinigungspads auch unzugängliche Eckbereiche des zu reinigen den Bodens erreichen. In an advantageous embodiment, the cleaning surface of the cleaning pad is designed as a Reuleaux triangle. A Reuleaux triangle is a constant thickness in which the distance between each point on one side and the opposite corner is constant. The constant width is retained when rotating around the center of the area. In combination with the variable axis of rotation, the cleaning result is improved. In particular, when the axis of rotation moves along a circular path, the circular movement of the axis of rotation and the movement of the cleaning pad can be coordinated such that the tips of the triangular cleaning pad also reach inaccessible corner areas of the floor to be cleaned.
Der Reinigungskörper kann mittels einer Antriebseinrichtung in Bewegung versetzbar sein, wobei die Antriebseinrichtung eine Getriebeanordnung umfasst. Dabei ist die Getriebeanordnung so ausgebildet, dass sowohl der Reinigungskörper in Rotation versetzt wird als auch die Auslenkung der Rotationsachse erfolgt. Dabei kann die Getriebeanordnung beispielsweise ein Kardangelenk oder eine Federwelle umfassen. The cleaning body can be set in motion by means of a drive device, the drive device comprising a gear arrangement. The gear arrangement is designed in such a way that both the cleaning body is in rotation is offset as well as the deflection of the axis of rotation takes place. The gear arrangement can for example comprise a cardan joint or a spring shaft.
Vorzugsweise ist die Getriebeanordnung als Zahnradgetriebe ausgebildet. Zahnrad getriebe sind kostengünstig und robust. The gear arrangement is preferably designed as a gear drive. Gear drives are inexpensive and robust.
Gemäß einer vorteilhaften Ausgestaltung der Getriebeanordnung kann dem Grund körper ein erstes Zahnrad mit einer Innenverzahnung zugeordnet sein, welches orts fest in dem Grundkörper angeordnet ist. In dem ersten Zahnrad rollt ein zweites Zahnrad mit einer Außenverzahnung ab. Der Durchmesser des zweiten Zahnrades ist dabei kleiner als der Innendurchmesser des ersten Zahnrades. Dadurch bewegt sich die Rotationsachse des zweiten Zahnrades entlang einer Kreisbahn. Des Weiteren rotiert das Zahnrad über seine Rotationsachse. Der Reinigungskörper wiederum ist an dem zweiten Zahnrad festgelegt und bewegt sich ebenfalls um dessen Rotationsachse. Dadurch beschreibt der Reinigungskörper eine überlagerte Taumel- und Rotationsbewegung. Im Zusammenhang mit der dreiecksförmigen Aus gestaltung des Reinigungspads ergibt sich dabei eine von dem Reinigungspad über- strichene Fläche, welche nahezu rechteckig ist. Dadurch ist das Reinigungspad in der Lage, auch Raumecken zu erreichen. According to an advantageous embodiment of the gear arrangement, the base body can be assigned a first gear with internal teeth, which is arranged in a fixed position in the base body. A second gear with external teeth rolls in the first gear. The diameter of the second gear is smaller than the inner diameter of the first gear. As a result, the axis of rotation of the second gear moves along a circular path. Furthermore, the gear rotates about its axis of rotation.

Die den Reinigungskörpern 4 zugeordnete Getriebeanordnung 9 weist eine Anord nung von Zahnrädern 12, 13 auf. Ein erstes Zahnrad 12 ist ortsfest an dem Grund körper 2 befestigt und weist eine Innenverzahnung auf. Ein zweites Zahnrad 13 rollt an der Innenverzahnung des ersten Zahnrades 12 ab, wobei der Außendurchmesser des zweiten Zahnrades 13 kleiner ist als der Innendurchmesser der Innenver zahnung des ersten Zahnrades 12. Die Rotationsachse des zweiten Zahnrades bildet jeweils die Rotationsachse 5 der Reinigungskörper 4. Das zweite Zahnrad 13 wird über einen Elektromotor in Rotation versetzt. Wird das zweite Zahnrad 13 in Rotation versetzt, erfolgt durch das Abrollen an der Innenverzahnung des ersten Zahnrades 12 eine kreisförmige Bewegung der Rotationsachse 5 des zweiten Zahnrades 13 und damit auch des dem zweiten Zahnrad 13 zugeordneten Reinigungskörper 4.
