Description

Reinigungsgerät  cleaner
Die Erfindung betrifft ein Reinigungsgerät, umfassend einen Grundkörper, eine Saugeinrichtung mit einer Säugöffnung und einem Saugkanal sowie einer Bürstenanordnung mit einer rotierbaren Bürstenwalze, wobei die Säugöffnung und die Bürstenwalze derart in dem Grundkörper angeordnet sind, dass diese dem zu reinigenden Boden zugewandt sind, wobei die Säugöffnung eine der Vorderkante des Grundkörpers zugewandte erste Wand und eine der The invention relates to a cleaning device, comprising a base body, a suction device with a mammal opening and a suction channel and a brush assembly with a rotatable brush roller, wherein the mammal opening and the brush roller are arranged in the base body, that they face the floor to be cleaned, wherein the Mammal opening one of the front edge of the main body facing the first wall and one of
Bürstenwalze zugewandte zweite Wand aufweist, wobei die Bürstenwalze ausgebildet ist, Verschmutzungen von dem zu reinigenden Boden zu lösen, wobei ferner eine Einrichtung zum Benetzen des zu reinigenden Bodens mit Flüssigkeit vorgesehen ist, welche der Bürstenwalze zugeordnet ist. Brush roller facing the second wall, wherein the brush roller is adapted to solve soiling of the soil to be cleaned, further comprising means for wetting the floor to be cleaned with liquid, which is associated with the brush roller.
Ein derartiges Reinigungsgerät ist aus der CN 205126117 U bekannt. Das Reinigungsgerät ermöglicht eine kombinierte trockene und feuchte Reinigung. Such a cleaning device is known from CN 205126117 U. The cleaning device allows a combined dry and damp cleaning.
Beim Bewegen des Reinigungsgerätes in einer Richtung gelangt zunächst die Säugöffnung in Kontakt mit den auf dem zu reinigenden Boden aufliegenden Verschmutzungen. Partikuläre und staubige Verschmutzungen werden dabei durch die Säugöffnung und den Saugkanal in einen Schmutzbehälter gefördert. Gleichzeitig wird der zu reinigende Boden mittels der Einrichtung mit einer Reinigungsflüssigkeit benetzt, welche an dem Boden anhaftende When moving the cleaning device in one direction, the infant opening initially comes into contact with the contaminants resting on the floor to be cleaned. Particulate and dusty dirt are conveyed through the mammal opening and the suction channel into a dirt container. At the same time, the floor to be cleaned is wetted by the device with a cleaning liquid which adheres to the floor
Verschmutzungen löst. Diese Verschmutzungen werden dann durch die Dirt dissolves. These contaminants are then removed by the
Bürstenwalze von dem zu reinigenden Boden entfernt. Die Säugöffnung wird entlang der Längskante von zwei Lippen begrenzt, welche in Richtung des zu reinigenden Bodens ragen. Die Lippen sind erforderlich, um den notwendigen Saugdruck zum Einsaugen partikulärer und flüssiger Verschmutzungen aufrechtzuerhalten. Bei dieser Ausgestaltung ist nachteilig, dass die Querschnittsbreite der Säugöffnung begrenzt ist und dadurch größere Partikel nicht von der Säugöffnung aufgenommen werden können. Die der Vorderseite zugeordnete Dichtlippe schiebt weiterhin in der Vorwärtsbewegung Teile der partikulären Verschmutzungen wie ein Räumschild eines Schneepfluges vor sich her, so dass diese nicht in den Saugkanal gelangen. Des Weiteren kann die der Bürstenwalze zugeordnete Dichtlippe einen Teil der aufzunehmenden Flüssigkeit vor sich herschieben, so dass diese in der Rückwärtsbewegung ebenfalls nicht in den Saugkanal gelangen kann. Brush roll away from the floor to be cleaned. The mammal opening is bounded along the longitudinal edge by two lips which project in the direction of the floor to be cleaned. The lips are required to maintain the necessary suction pressure to draw in particulate and liquid contaminants. In this embodiment, it is disadvantageous that the cross-sectional width of the mammal opening is limited and thereby larger particles can not be absorbed by the mammal opening. The sealing lip assigned to the front further pushes parts of the particulate contaminants, such as a plow blade of a snowplough, forward in the forward movement so that they do not enter the suction channel. Furthermore, the sealing lip assigned to the brush roller can push a part of the liquid to be absorbed in front of it so that it can not enter the suction channel in the rearward movement either.
Der Erfindung liegt die Aufgabe zugrunde, ein Reinigungsgerät bereitzustellen, welches eine verbesserte Aufnahme partikulärer und feuchter The invention has for its object to provide a cleaning device, which improves the uptake particulate and moister
Verschmutzungen ermöglicht. Pollution allows.
Diese Aufgabe wird mit den Merkmalen von Anspruch 1 gelöst. Auf vorteilhafte Ausgestaltungen nehmen die Unteransprüche Bezug. This object is achieved with the features of claim 1. In advantageous embodiments, the dependent claims relate.
Zur Lösung der Aufgabe ist der Säugöffnung eine Lippe schwenkbar To solve the problem of the mammal opening a lip is pivotable
zugeordnet, welche sich wechselweise an die erste Wand oder die zweite Wand der Säugöffnung anlegt. Das wechselweise Anlegen der Lippe an die erste Wand oder die zweite Wand erfolgt dabei vorzugsweise in Abhängigkeit der Bewegungsrichtung des Reinigungsgerätes. Wird das Reinigungsgerät in eine Richtung, beispielsweise vorwärts bewegt, legt sich die Lippe an die der Bürstenwalze zugewandten zweiten Wand an, so dass sich entlang der associated, which alternately applies to the first wall or the second wall of the mammalian opening. The alternate application of the lip to the first wall or the second wall is preferably carried out as a function of the direction of movement of the cleaning device. If the cleaning device in one direction, for example moved forward, the lip is applied to the brush roller facing the second wall, so that along the
Vorderkante im Bereich der ersten Wand ein Spalt öffnet, durch welchen Schmutz, insbesondere partikuläre Verschmutzung über die Säugöffnung in den Saugkanal gelangt. Bei der Bewegung in der entgegengesetzten Richtung, beispielsweise rückwärts liegt die Lippe an der ersten Wand an, so dass sich ein Spalt im Bereich der zweiten Wand öffnet, durch welchen der von der Bürstenwalze angelöste Schmutz und die von der Einrichtung aufgebrachte Flüssigkeit in den Saugkanal gelangt. Bei dieser Ausgestaltung ist vorteilhaft, dass die Anordnung nur eine einzige Lippe benötigt. Es ist insbesondere nicht erforderlich, beide Längskanten der Säugöffnung jeweils separat mit einer Lippe zu begrenzen. Dadurch, dass die Lippe schwenkbar in den Grundkörper angeordnet ist, kann einerseits im Bereich der Vorderkante ein größerer Querschnitt für die Säugöffnung bereitgestellt werden. Dadurch kann diese größere Partikel aufnehmen. Andererseits fungiert die Lippe in der anderen Bewegungsrichtung als Abziehlippe und schiebt die Flüssigkeit vor sich her, so dass diese von der Säugöffnung aufgenommen wird. Leading edge in the region of the first wall opens a gap through which dirt, in particular particulate contamination passes through the mammal opening into the suction channel. When moving in the opposite direction, For example, backwards, the lip rests against the first wall, so that a gap opens in the region of the second wall, through which the dirt dissolved by the brush roller and the liquid applied by the device pass into the suction channel. In this embodiment, it is advantageous that the arrangement requires only a single lip. In particular, it is not necessary to separate both longitudinal edges of the mammal opening separately with a lip. The fact that the lip is pivotally arranged in the base body, on the one hand in the region of the front edge, a larger cross section for the mammalian opening can be provided. This allows them to absorb larger particles. On the other hand, in the other direction of movement, the lip functions as a lancing lip and pushes the liquid in front of it so that it is picked up by the mammal opening.
Die Lippe liegt vorzugsweise auf dem zu reinigenden Boden auf. Dadurch ist sichergestellt, dass sich die Lippe in Abhängigkeit der Bewegungsrichtung des Reinigungsgerätes verschwenken kann. Des Weiteren verbessert sich insbesondere die Saugleistung der Säugöffnung. The lip is preferably on the floor to be cleaned. This ensures that the lip can pivot depending on the direction of movement of the cleaning device. Furthermore, in particular the suction performance of the infant opening improves.
Die Lippe kann als Kipphebel geformt sein und schwenkbar in dem The lip may be shaped as a rocker arm and pivotable in the
Grundkörper festgelegt sein. Bei dieser Ausgestaltung kann die Lippe entlang einer Längskante eine Verdickung aufweisen, welche in einer kongruenten Ausnehmung des Grundkörpers angeordnet ist. Be determined body. In this embodiment, the lip along a longitudinal edge may have a thickening, which is arranged in a congruent recess of the base body.
Der Ausnehmung kann ein V-förmiger Schlitz zugeordnet sein, durch den die Lippe hindurchragt. Dadurch bildet sich ein Hinterschnitt, welcher die Lippe in dem Grundkörper fixiert. Durch den V-förmigen Schlitz ergibt sich die The recess may be associated with a V-shaped slot through which the lip protrudes. This forms an undercut, which fixes the lip in the body. The V-shaped slot results in the
Verschwenkbarkeit der Lippe. Pivotability of the lip.
Nach einer vorteilhaften Ausgestaltung ist die Lippe schräg angestellt, wenn sich die Lippe an die zweite Wand anlegt und senkrecht zu dem zu reinigenden Boden angestellt ist, wenn die Lippe an der ersten Wand anliegt. Dadurch liegt die Lippe mit Vorspannung auf dem zu reinigenden Boden auf, wenn die Lippe an der ersten Wand anliegt. Dadurch erhöht sich die Reinigungsleistung gegenüber Flüssigkeiten. Liegt die Lippe an der zweiten Wand an, ist die Vorspannung geringer, so dass das Manövrieren des Reinigungsgerätes vereinfacht ist. According to an advantageous embodiment, the lip is turned obliquely when the lip rests against the second wall and perpendicular to the to be cleaned Floor is made when the lip rests against the first wall. As a result, the lip is biased on the floor to be cleaned when the lip abuts the first wall. This increases the cleaning performance against liquids. If the lip is against the second wall, the preload is lower, so that the maneuvering of the cleaning device is simplified.
Die Lippe kann mit zumindest einer Durchbrechung versehen sein. Dadurch kann die Lippe so in dem Saugkanal angeordnet sein, dass diese zwischen Saugkanal und Säugöffnung angeordnet ist. Wenn die Lippe an der zweiten Wand anliegt, wird die strömungsleitende Verbindung zwischen dem zu reinigenden Boden und dem Saugkanal über die zumindest eine The lip can be provided with at least one opening. As a result, the lip can be arranged in the suction channel so that it is arranged between the suction channel and the mammalian opening. When the lip bears against the second wall, the flow-conducting connection between the floor to be cleaned and the suction channel over the at least one
Durchbrechung hergestellt. Die Durchbrechung kann in Form eines Schlitzes oder in Form von mehreren runden oder eckigen Durchbrüchen geformt sein. Liegt die Lippe an der ersten Wand an, erfolgt keine Luftströmung durch die zumindest eine Durchbrechung. Opening made. The opening may be shaped in the form of a slot or in the form of several round or square openings. If the lip is against the first wall, there is no air flow through the at least one opening.
