发明名称 Floor washing-drying machine with automatically orienting scraping device
摘要 A floor washing-drying machine including a scraping device that is capable of automatic orientation. The scraping device follows changes of direction of the machine by a simple and effective orienting mechanism so as to wipe all the surface washed by a washing mechanism, without leaving any wet portions on the surface. An idle mode mechanism is achieved by a bushing to which the scraping device is connected. The bushing is mounted in an idle and axially slidable mode on the brush rotation shaft.

主权项 1. A floor washing-drying machine comprising: a motor for driving a rotating shaft of one or more brushes adapted to scrub a washing liquid onto a floor; a head including the brushes; a scraping device to scrape the liquid after washing; wherein the scraping device is mounted with respect to the rotating shaft in neutral, at an axial distance from the brushes and is maintained behind the brushes due to friction onto the floor, during forward and steering movements of the machine, while when the head is lifted up from the floor, due to gravity, the axial distance between brushes and scraping device becomes zero and the scraping device is engaged by means of rotation of the brushes to be positioned always behind the brushes, during backwards movement.
