Technical Field of the Invention This invention relates to a floor cleaning device.
Background In the floor cleaning sector, floor cleaning devices are known comprising a stick with a cleaning head at one end thereof; a tank for a cleaning liquid normally consisting of a mixture of water and detergent; and a basket mounted on the tank and fluidically 1 5 connected to the tank to allow the cleaning head to be wrung.
Generally, the cleaning head comprises a stick attachment flange to allow the cleaning head to be attached to the stick and multiple bristles; and the basket has multiple openings to fluidically connect the tank and the basket.
The above-described know floor cleaning devices have some drawbacks mainly
2 0 due to the fact that the cleaning liquid contained in the tank is contaminated by dirt discharged from the cleaning head when the latter is rinsed inside the tank and when it is wrung inside the basket.
As a result, the cleaning action is compromised by rinsing the cleaning head into the contaminated/dirty cleaning liquid contained in the tank.
cleaning device that offers, in part, a solution to the above-described drawback is disclosed in US 2006/151054 Al and comprises a stick with a cleaning head at one end thereof, an upper tank for a cleaning liquid, a lower tank, and a basket for rinsing the cleaning head. The upper and lower tanks are separated, and the basket can be fluidically connected to the upper tank to receive the cleaning liquid and can be emptied 30 into the lower tank after the cleaning head has been rinsed in the basket. This solution, although better than solutions in which the cleaning head is rinsed in the same tank that contains the clean cleaning liquid, still has limitations, both in terms of rinsing effectiveness and in terms of operation complexity.

The floor cleaning device 1 further comprises a second basket 18, which, in the embodiment shown, has a cylindrical shape and is carried by the upper tank 9, extends through the body 16 and the bottom walls 17 and 10 in the insertion direction 12, and projects into the lower tank 6.
The basket 18 is provided with multiple upper connection holes 19 and multiple 2 0 lower connection holes 20.
The basket 18 is slidably coupled to the body 16 to move between a raised rest position (Figure 3), where the upper connection holes 19 are arranged inside the body 16 and outside the upper tank 9, the lower connection holes 20 are arranged inside the lower tank 6, and the lower and upper tanks 6, 9 are mutually fluidically separated by the basket 18, and a lowered operating position (Figure 4), where the upper connection holes 19 arc arranged outside the body 16 and inside the tank 9, the lower connection holes 20 are arranged inside the tank 6, and the lower and upper tanks 6, 9 are mutually fluidically connected by the basket 18, The basket 18 is moved, and normally kept, in the raised rest position by the thrust exerted by multiple springs 21 arranged between the body 16 and the basket 18.
The basket 18 is moved from the raised rest position to the lowered operating position by the thrust exerted on the basket 18 by the flange 4 of the cleaning head 3.
In use, the bristles 5 of the cleaning head 3 are wrung into the basket 14 in order
4 to feed the contaminated/dirty cleaning liquid into the lower tank 6 through the connection holes 15.
At this point, the head 3 is moved inside the basket 18 and the basket 18 is moved from the raised rest position to the lowered operating position by means of the flange 4 so as to mutually fluidically connected the lower and upper tanks 6, 9 and cause the uncontaminated/clean cleaning liquid in the upper tank 9 to flow from the upper tank 9 to the lower tank 6, through the basket 18, so resulting in the bristles 5 being rinsed.
In other words, when the basket 18 is moved to the lowered operating position, the uncontaminated/clean cleaning liquid in the upper tank 9 first flows into the basket 18 through the upper connection holes 19 and then into the lower tank 6 through the lower connection holes 20.
The floor cleaning device 1 is advantageous compared to the known floor cleaning devices mainly due to the fact that basket 18 prevents the bristles 5 from immersing into the contaminated/dirty cleaning liquid both in the lower tank 6 and in the uncontaminated/clean cleaning liquid in the upper tank 9, and allow the bristles 5 to be rinsed only with the uncontaminated/clean cleaning liquid in the upper tank 9.
In alternative embodiments not shown, the basket 14 may be omitted and the bristles 5 may be wrung and rinsed inside the basket 18; the basket 18 may be moved from the raised rest position to the lowered operating position directly by a user, e.g., 2 0 via a foot pedal mechanism; and the cleaning head 3 may be replaced with a cleaning head with cleaning elements other than the bristles 5.
At this point, the head 3 is moved inside the basket 18 and the basket 18 is moved from the raised rest position to the lowered operating position by means of the flange 4 so as to mutually fluidically connected the lower and upper tanks 6, 9 and cause the uncontaminated/clean cleaning liquid in the upper tank 9 to flow from the upper tank 9 to the lower tank 6, through the basket 18, so resulting in the bristles 5 being rinsed.
In other words, when the basket 18 is moved to the lowered operating position, the uncontaminated/clean cleaning liquid in the upper tank 9 first flows into the basket 18 through the upper connection holes 19 and then into the lower tank 6 through the lower connection holes 20.
The floor cleaning device 1 is advantageous compared to the known floor cleaning devices mainly due to the fact that basket 18 prevents the bristles 5 from immersing into the contaminated/dirty cleaning liquid both in the lower tank 6 and in the uncontaminated/clean cleaning liquid in the upper tank 9, and allow the bristles 5 to be rinsed only with the uncontaminated/clean cleaning liquid in the upper tank 9.
In alternative embodiments not shown, the basket 14 may be omitted and the bristles 5 may be wrung and rinsed inside the basket 18; the basket 18 may be moved from the raised rest position to the lowered operating position directly by a user, e.g., 2 0 via a foot pedal mechanism; and the cleaning head 3 may be replaced with a cleaning head with cleaning elements other than the bristles 5.
