| 20150359398 | FLOOR WASHING-DRYING MACHINE WITH A SCRAPING DEVICE - A washing-drying machine including a scraping device including a reversible fastening system of scraping blades. The reversible fastening system makes it possible to apply the scraping blades to the scraping device in a simple and safe way and as simply to remove them to clean them or replace them when worn out through a flexible fastening mechanism including holes for engaging with support elements provided on the scraping device, and including at least an elastic end portion with a slot for engaging with the undercut of a corresponding locking element, formed in the proximity of end portions of the support. | 12-17-2015 |
| 20150129353 | Silencer System For A Vacuum Motor In A Suction Cleaner - The present invention relates to a silencer system for a vacuum motor in a suction cleaner, which may be constructed using only one or two parts to form a housing for the vacuum motor including the silencer system. The system may have a main fan silencer system for the main fan and a second motor cooling silencer system for the motor cooling fan. The main fan is encapsulated in a housing surrounded by a substantially circular first wall part in such a way that a first cavity is formed between the housing and the first wall part. The system further includes two ducts, each duct connected at one end with a serpentine shaped exhaust air duct and at the other end with a second cavity connected with the first cavity by an opening in the first wall part. | 05-14-2015 |
| 20150008997 | APPARATUS FOR FLOOR CLEANING, WITH IMPROVED KEY - Apparatus for floor cleaning, having a cavity that opens on the dashboard, a plurality of mechanically similar interchangeable keys, and suitable to be inserted completely into and operate with said cavity, two or more Hall-effect sensors arranged outside said cavity, at least one first key containing at least one magnet, and at least one second key including at least one respective second magnet, which are in functional correspondence with respective predefined sensors. | 01-08-2015 |
| 20140332545 | Tipping Arrangement Of A Movable Cleaning Unit - A tipping method for a tipping arrangement which includes a first element ( | 11-13-2014 |
| 20140210265 | Battery Control System - A method and a system for controlling the charging and discharging of one or more battery packs ( | 07-31-2014 |
| 20130263406 | FILTER CLEANING FOR DIRT SUCTION DEVICES COMPRISING AN EXTERNAL FAN - A dirt suction device comprises at least two filters ( | 10-10-2013 |
| 20130160225 | FLOOR WASHING-DRYING MACHINE WITH AUTOMATICALLY ORIENTING SCRAPING DEVICE - 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. | 06-27-2013 |
| 20130127397 | Combined Primary And Secondary Units - A system has a primary unit ( | 05-23-2013 |
| 20110289716 | PORTABLE CLEANING SYSTEM - A portable vacuum cleaning system includes a portable vacuum unit for cleaning debris. The vacuum unit is powered by a self-contained first electric power storage device and may be carried with a strap in backpack-fashion. The system also includes a cart defining a receptacle for receiving the vacuum unit. The vacuum unit may be used when supported by the cart or when carried by an operator. A second electric power storage device is supported by the cart and electrically connectable to the vacuum unit for charging the first electric power storage device when the vacuum unit is supported by the cart. Further, when disposed in the cart, the vacuum unit is disposed at an angle of about 45 degrees allowing for ease of movement of the cart. | 12-01-2011 |
| 20110226130 | FILTER CLEANING IN A VACUUM HAVING A FLAP ELEMENT - The invention relates to filter cleaning in a vacuum having a switchable flap element, the cleaning of the filter or of parts of the filter being carried out by supplying a secondary air flow to the interior of the filter to be cleaned, and air being able to flow through the filters separately from each other from the outside to the inside in the vacuum container in a sealed manner, and a flap element disposed in a chamber housing being pivotable, by means of the pivoting of which openings may be closed and released, the secondary air flow reaching the surface of the filter to be cleaned from the inside toward the outside in pulses, characterized in that the flap element comprises at least two partial flaps, the pivoting of which is actuated by a pivot drive, the respective partial flap optionally closes the outflow opening of the respective filter chamber in the direction of the intake opening of the suction turbine, the blow-out side of the suction turbine delivers the created overpressure air into an overpressure chamber in which a chamber housing is disposed, the at least one drive element to be suddenly actuated comprises openings to be opened and closed, upon the opening of which the overpressure air flows through the chamber housing optionally into an impulse channel which branches off at that location and introduces the air into one or into the other filter chamber for cleaning. | 09-22-2011 |
