Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application refers to Italian patent application no. Related to issue 2.

The present invention relates to a floor cleaning device.

In the field of floor cleaning, a handle containing a cleaning head at one end, a tank for a cleaning liquid, usually consisting of a mixture of water and detergent, and a handle mounted on the tank and fluidly connected to the tank so that the cleaning head can be squeezed. A floor cleaning device is known which comprises a basket and a basket.

Generally, the cleaning head includes a handle attachment flange that allows the cleaning head to be attached to the handle and a number of bristles, and the basket has a number of openings for fluid connection between the tank and the basket.

The above-mentioned known floor cleaning devices mainly require that the cleaning liquid contained in the tank is contaminated by dirt released from the cleaning head when it is flushed in the tank and when the cleaning head is squeezed in the basket. It has some drawbacks due to the fact that

Consequently, the cleaning operation is disturbed by flushing the cleaning head in the contaminated/dirty cleaning liquid contained within the tank.

A cleaning device that proposes a partial solution to the above-mentioned drawbacks is disclosed in US Pat. Equipped with a basket for washing. The upper and lower tanks are separated and a basket can be fluidly connected to the upper tank to receive the cleaning liquid, which after the cleaning head is flushed within the basket flows out to the lower tank and empties. obtain. Although this solution is better than one in which the cleaning head is flushed in the same tank containing the clean cleaning liquid, it still has limitations both in terms of flushing effectiveness and in terms of operational complexity.

US Patent Application Publication No. 2006/151054A1

The object of the invention is to provide a floor cleaning device which does not have the above-mentioned drawbacks and is simple and inexpensive to manufacture.

According to the invention, a floor cleaning device is provided as claimed in the appended claims.

The invention will now be described with reference to the accompanying drawings, which show non-limiting embodiments.

1 is a schematic perspective view of a preferred embodiment of a floor cleaning device according to the invention, with some parts removed for clarity; FIG. 2 is a schematic perspective view of the floor cleaning device shown in FIG. 1, with some parts removed for clarity and some parts shown in cross-section; FIG. 2 is a detailed sectional view along the line III-III of the floor cleaning device shown in FIG. 1 in different operating positions; FIG. 2 is a detailed sectional view along the line III-III of the floor cleaning device shown in FIG. 1 in different operating positions; FIG.

With reference to FIGS. 1, 2, 3 and 4, reference numeral 1 indicates the entire floor cleaning device. The floor cleaning device comprises an elongated handle 2 with a cleaning head 3 at one free end.

The cleaning head 3 includes a flange 4 for attaching the cleaning head 3 to the handle 2, and a large number of cleaning bristles 5 fixed to the flange 4.

The floor cleaning device 1 further includes a lower tank 6. The lower tank 6, in the illustrated embodiment, has a cup shape and is bounded at the bottom by a substantially flat and horizontal bottom wall 7 and laterally by substantially vertical side walls 8. It will be done.

The floor cleaning device 1 further includes an upper tank 9. The upper tank 9 is removably inserted into the tank 6 and extends into the tank 6 and is designed to contain a cleaning liquid, for example consisting of a mixture of water and detergent.

The upper tank 9 is bounded at the bottom by a substantially flat bottom wall 10 and laterally by substantially vertical side walls 11 .

The upper tank 9 is slidably coupled to the lower tank 6 and projects from the side wall 8 into the lower tank 6 so as to stop the side wall 10 at a certain distance from the bottom wall 7 in a substantially vertical insertion direction 12 . by at least one tooth 13 extending along 8.

The upper tank 9 includes a first basket 14 . The first basket 14 has a cylindrical shape in the illustrated embodiment and extends through the upper tank 9 and the bottom wall 10 in the insertion direction 12 and projects into the lower tank 6 .

The first basket 14 is fluidly separated from the upper tank 9 and has a number of connecting holes 15 formed outside the upper tank 9 and fluidly connecting the basket 14 and the lower tank 6.

The upper tank 9 further includes a main body 16. The body 16 , in the illustrated embodiment, has a cylindrical cup shape and extends into the upper tank 9 in the insertion direction 12 and is lower than the height of the upper tank 9 measured parallel to the insertion direction 12 . It has a low height, again measured parallel to the insertion direction 12.

The body 16 is delimited at the bottom by a bottom wall 17 which is arranged at a predetermined distance with respect to the bottom wall 10 .

The floor cleaning device 1 further includes a second basket 18. The second basket 18, in the illustrated embodiment, has a cylindrical shape and is carried by the upper tank 9 and extends in the insertion direction 12 through the main body 16, the bottom wall 17 and the bottom wall 10, and It protrudes into the tank 6.

The basket 18 includes a large number of upper connecting holes 19 and a large number of lower connecting holes 20.

The basket 18 is in the raised resting position (FIG. 3), with the upper connecting hole 19 disposed within the main body 16 and outside the upper tank 9, the lower connecting hole 20 disposed within the lower tank 6, and the lower and upper tanks 6, 9 are fluidly separated from each other by a basket 18 in a raised rest position and in a lowered working position (FIG. 4), with the upper connection hole 19 located outside the body 16 and within the tank 9 and the lower connection A bore 20 is disposed within the tank 6 and is slidably coupled to the body 16 for movement between a lowered operating position in which the lower and upper tanks 6, 9 are fluidly connected to each other by the basket 18.

The basket 18 is moved by a thrust force exerted by a number of springs 21 arranged between the body 16 and the basket 18 and is normally maintained in a raised rest position.

The basket 18 is moved from the raised rest position to the lowered operating position by the thrust force 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 squeezed into the basket 14 to admit the contaminated/dirty cleaning liquid through the connecting hole 15 into the lower tank 6.

At this time, the head 3 is moved within the basket 18, and the basket 18 is moved by the flange 4 from the raised rest position to the lowered operating position, whereby the lower and upper tanks 6, 9 are fluidly connected to each other and the upper tank The uncontaminated/clean cleaning liquid in 9 flows from the upper tank 9 to the lower tank 6 through the basket 18, with the result that the bristles 5 are washed away.

In other words, when the basket 18 is moved to the lower operating position, the uncontaminated/clean cleaning liquid in the upper tank 9 first flows into the basket 18 through the upper connecting hole 19 and then through the lower connecting hole 19. It flows into the lower tank 6 through the hole 20.

The floor cleaning device 1 mainly prevents the basket 18 from soaking the bristles 5 in the contaminated/dirty cleaning solution in the lower tank 6 as well as in the uncontaminated/clean cleaning solution in the upper tank 9. , is advantageous compared to known floor cleaning devices since it allows the bristles 5 to be washed away only with uncontaminated/clean cleaning liquid in the upper tank 9.

In an alternative embodiment, not shown, the basket 14 may be omitted and the bristles 5 may be wrung out and washed away within the basket 18, and the user may raise the basket 18 directly, e.g. by a foot pedal mechanism. position to a lowered operating position and the cleaning head 3 may be replaced by a cleaning head containing cleaning elements other than bristles 5.
