Abstract

The scrubbing roller (3) is located on a one-sidedly tensioned, free arm shaft (7) on the machine frame (1). The suction head (2) is axially displaceable (P) in relation to the scrubbing roller. A parallelogram rod (4,5) with return spring (6) is used as a guide component to regulate the axial displacement. The rod and the return spring are arranged on the underside (1a) of the machine. The guide and alignment components for the suction hood are located at least partly in the interior of the housing of the cleaning machine.

Description

Die Erfindung bezieht sich nach dem Oberbegriff des Pa­ tentanspruchs 1 auf eine Fußboden-Naßrei­ nigungsmaschine, sie geht dabei aus von einem Gerät, wie es beispiels­ weise in der US-PS 48 17 233 beschrieben ist. The invention relates to the preamble of Pa claim 1 to a wet floor cleaning machine, it assumes a device such as that as described in US-PS 48 17 233.  

Die Problematik bei allen bislang bekannten Maschinen dieser Gattung besteht bezüglich des Trockensaugens der zu bearbeitenden Bodenflächen vor allem darin, daß zur Erzielung der gewünschten Saugwirkung einerseits die Saughaube einen gewissen Überstand über die Enden der Scheuerwalze haben muß, was zum anderen wiederum den Nachteil mit sich bringt, daß man bei entsprechend großem Überstand zwangsläufig mit der Scheuerwalze nicht nahe genug an Ecken und Kanten heranfahren kann und dort somit Schmutzstreifen verbleiben.The problem with all previously known machines this genus exists with regard to dry vacuuming to be processed floor surfaces especially in that for Achieving the desired suction on the one hand Suction hood a certain protrusion over the ends of the Scrubbing roller must have, which in turn the Disadvantage that you can with accordingly large excess with the scrubbing roller inevitably can get close enough to corners and edges and there thus streaks of dirt remain.

Die vorliegende Erfindung hat sich daher die Aufgabe ge­ stellt, eine Bauweise bzw. Anordnung bezüglich der Saug­ haube zu treffen, die auch ein volles Heranfahren der Scheuerwalze an Raumkanten und somit eine vollkommene Reinigung solcher Bodenflächen ermöglicht.The present invention therefore has the task ge represents a construction or arrangement regarding the suction hood to hit, which is also a full drive up the Scrubbing roller on room edges and thus a perfect one Allows cleaning of such floor surfaces.

Gelöst wird diese Aufgabe dabei gemäß den kennzeichnenden Merkmalen des Patentanspruchs 1. This object is achieved according to the characterizing features of the patent claim 1.  

Die Saughaube kann sich somit also beim Herausfahren mit der Bürstenwalze an Kanten maximal bis zur lot­ rechten Ebene der freien Scheuerwalzen-Stirnfläche "zurückziehen" und damit unter Beibehaltung der vollen Saugwirkung ein kantengenaues Reinigen der betreffenden Bodenfläche ermöglichen. Spezielle bauliche Ausgestal­ tungsmerkmale dieser Erfindung sind noch in den Unter­ ansprüchen aufgeführt und zudem anhand einer Zeichnungs­ skizze näher erläutert.The suction hood can thus move out with the brush roller on edges up to a maximum right level of the free scrubbing roller face "withdraw" and thus while maintaining the full Suction an edge-precise cleaning of the concerned Allow floor space. Special structural design tion features of this invention are still in the sub claims listed and also based on a drawing sketch explained in more detail.

Fig. 1 eine Fußbodenreinigungsmaschine schematisch dargestellt in Seiten­ ansicht und Fig. 1 is a floor cleaning machine shown schematically in side view

Fig. 2 eine Ansicht auf die Maschine von unten. Fig. 2 is a view of the machine from below.

Die in Fig. 1 rein schematisch im Aufriß angedeutete Fußbodenreinigungsmaschine 1 besitzt in ihrem Frontbe­ reich eine Scheuerwalze 3 mit dieser übergreifender Saughaube 2; es wird also der gesamte Reinigungsvor­ gang mit Wasserzufuhr, Scheuern und Trockensaugen in an sich bekannter Weise im Frontbereich der Maschine vollzogen. Kombinatorisch neu hierbei ist gemäß Fig. 2 nun, daß die motorisch angetriebene Scheuerwalze 3 auf einer lediglich einseitig eingespannten (Freiarm-) Achse innerhalb der diese beidseits stirnseitig über­ deckenden Saughaube 2 umläuft, wobei diese Saughaube 2 gegenüber der Scheuerwalze 3 axialverschieblich ge­ führt ist.The floor cleaning machine 1 indicated purely schematically in FIG. 1 has in its front area a scrubbing roller 3 with this overlapping suction hood 2 ; So the entire cleaning process with water supply, scrubbing and dry vacuuming is carried out in a manner known per se in the front area of the machine. Combinatorially new case 2 is shown in FIG. Now that the motor-driven scrubbing roller 3 within which rotates on a purely cantilever (free-arm) axis, this on either side of the end face covering suction hood 2, wherein said suction hood 2 takes over the abrasive roller 3 axially displaceable ge is.

In spezieller baulicher Ausgestaltung ist bei dem hier dargestellten Ausführungsbeispiel dabei vorgesehen, daß als Führungselement für die Axialverschieblich­ keit der Saughaube 2 ein ( Parallelogramm-)Gestänge 4, 5 mit Rückstellfeder 6 dient, wobei Gestänge 4, 5 und Rückstellfeder 6 an der Maschinenunterseite 1a freiliegend oder geschützt im Gehäuseinneren angeordnet sind. Außerdem kann anstelle der zeichnerisch nur als Beispiel dargestellten Lösung, auch jede andere Form der Linearführung der Saughaube 2 Verwendung finden und anstelle der Rückstellfeder 6 jede andere bekannte Art von Ausrichtelementen.In a special structural design it is provided in the embodiment shown here that a (parallelogram) linkage 4 , 5 with return spring 6 is used as the guide element for the axially displaceable speed of the suction hood 2 , linkage 4 , 5 and return spring 6 on the underside of the machine 1 a are exposed or protected inside the housing. In addition, instead of the solution shown in the drawing only as an example, any other form of linear guide of the suction hood 2 can be used and instead of the return spring 6 any other known type of alignment elements.
