Definitions
- the invention relates to a cleaning device for cleaning a surface, the cleaning device comprises at least one brush rotatable in a rotation direction and movable over the surface to be cleaned and at least one deflector contacting the bristles of the brush at a location, seen in the rotation direction, before the location where the bristles contact the surface to be cleaned.
- the invention also relates to a vacuum cleaner.
- a rotatable brush is being used to aid in the loosening and removal of dirt and foreign material from the surface to be cleaned.
- the brush is pressed against the surface.
- a cleaning liquid is being used.
- the cleaning liquid is removed from the surface by means of the rotating brush, together with the dirt.
- Droplets of the cleaning liquid on the inside of the housing of the brush are guided back to the brush by means of the deflector.
- the deflector must be pressed firmly against the brush. This has the disadvantage that the power needed to rotate the brush is increased and brush wear will be more.
- the deflector is not sufficiently pressed against the brush, droplets will fall back to the surface, which will negatively effects the cleaning result.
- the cleaning device in that the deflector is movable against spring force when the bristles of the brush are getting in contact with the deflector when the brush is being rotated.
- Both the deflector and the bristles of the brush will be moved when getting in contact with each other when the brush is being rotated. If the brush is worn or deformed, the deflector is will still keep in touch with the brush, although in this situation the deflector will be moved less. In case that the diameter of the brush is larger than expected, for example due to production tolerances, the deflector will be moved more.
- the deflector can be used for preventing droplets of water or cleaning liquid from falling back on the cleaned surface.
- the cleaning device is also suitable for cleaning without cleaning liquid.
- the bristles are pressed together by the deflector, whereby air will be pushed out of the area between the bristles. Between the deflector and the surface to be cleaned, the bristles will be moved apart and the area between the bristles will increase so that air will be sucked into the brush. Because the air is sucked into the brush close to the position where the brush is pressed together by the surface to be cleaned, the blowing of air caused by the surface to be cleaned is compensated for. Also in this case, an optimal balance between a sufficient contact with the brush to create suction and a minimum power dissipation by the motor due to the contact between the brush and the deflector can be obtained.
- the deflector itself can be relatively stiff and be mounted by means of springs to the housing of the brush or the deflector can be flexible and be moved with respect to the brush by being bent.
- the deflector comprises at least one flexible plate-shaped element being bendable against spring force of the plate-shaped element.
- the plate-shaped element can be made of a plastic like silicon rubber, a polymer or any other suitable material like natural rubber.
- a further embodiment of the cleaning device according to the invention is characterized in that the stiffness of the deflector is less than 200* 10 -3 N/mm, preferably 20* 10 -3 N/mm and more preferably 2* 10 -3 N/mm per millimetre length of the brush.
- the deflector extends relatively far into the brush, for example 2 mm or more, when the brush is not rotated so that a good contact between the deflector and brush during rotation is ensured, whereby nearly no wear of the brush due to the contact with the deflector will occur and the power dissipation of the motor due to this contact will be relatively low.
- the deflector is very elastic, and has a stiffness of less than 2* 10 -3 N/mm per millimetre length of the brush. At a brush with a length of 250 mm, the total stiffness is 2* 10 -3 N/mm * 250 mm is 0,5 N/mm.
- the stiffness of the deflector can be determined, for example, by exerting a bending force, i.e. a force having the effect that the deflector is subjected to a bending deformation, on the end of the deflector extending in normal use into the brush until the end has moved 1 mm.
- a bending force i.e. a force having the effect that the deflector is subjected to a bending deformation
- Another embodiment of the cleaning device according to the invention is characterized in that the bristles are bent by the deflector to an extend that suction between the bristles when losing contact with the deflector is larger than expellation of air from between the bristles when contacting the surface to be cleaned.
- the axle of the brush is kept at a certain predetermined distance from the surface, for example by means of wheels connected to a housing of the cleaning device.
- Another embodiment of the cleaning device according to the invention is characterized in that the bending of the bristles by the deflector is larger than the bending of the bristles by the surface to be cleaned.
- a further embodiment of the cleaning device according to the invention is characterized in that the cleaning device comprises at least two brushes rotatable in opposite directions directed towards each other at the surface to be cleaned, whereby at least two deflectors are provided pressing against the bristles of the brushes, each deflector is located on a side of a brush remote from the other brush.
- a further embodiment of the cleaning device is characterized in that the deflector is adjustable with respect to the brush. In this manner the pressure between the deflector and the brush can be varied. Moreover one can compensate for possible wear of the bristles.
- an embodiment of the cleaning device according to the invention is characterized in that the cleaning device is provided with at least one side deflector pressing against the bristles of the brush located near an end of the brush.
- Water inside the housing of the cleaning device will fall either on the deflector or on the side deflector and will be guided back into the brush. No stripes or droplets will occur on the cleaned surface. If droplets on the surface will occur, this will be an indication that the brushes have been worn and should be replaced by new fresh brushes.
- Fig. 1 is a side view of a rotatable brush according to the prior art.
- air will be expelled from the rotating brush in the direction indicated by arrow P1 when contact is made at position A with the surface to be cleaned.
- the air will be expelled from the brush from the position A to position B.
- From position B air will be sucked in a direction indicated by arrow P2 into the brush to compensate for the increasing volume between the bristles, until the bristles have lost contact with the surface (position C).
- the airflow in the direction indicated by arrow P2 towards the brush aids the cleaning action of the brush.
- the airflow in the direction indicated by arrow P1 away from the brush is detrimental to the cleaning action since dirt will be blown away.
- Fig. 2 shows a perspective view of a cleaning device 1 according to the invention, comprising a housing 2 in which two brushes 3, 4 are rotatably mounted around axles 5, 6.
- the brushes 3, 4 are driven by a motor (not shown).
- the motor might be located on any suitable position whereby via gears of belts the brushes 3, 4 are being rotated with a speed of 5000-10,000 rotations per minute.
- the axle of the motor can also be directly connected to the axle of the brush, whereby the motor can be placed inside the brush, for example.
- the diameter of the brushes for example is 4 cm à 6 cm.
- the length of the brush is for example about 25 cm.
- Brush 3 is rotatable in a clockwise direction, indicated by arrow P3 and brush 4 is rotatable in a counter clockwise direction, indicated by arrow P4 around the respective axles 5, 6.
- the housing 2 is provided with wheels (not shown) keeping the axles 5, 6 at a predetermined distance of the surface to be cleaned.
- the housing 2 is connected via a steering joint to a stick 7 which is provided on a side remote of the housing 2 with a handle 8.

- the brushes 3, 4 rotate in opposite directions P3, P4, which directions are directed towards each other near the surface to be cleaned 16.
- the bristles 17 of the brushes 3, 4 rub over the surface to be cleaned 16 and the dirt and other materials are being disconnected from the surface to be cleaned 16 and are being moved upwards in the direction of arrow P5 into the entrance 12 of the debris collecting chamber 11.
- the bristles 17 of the brushes 3, 4 reach the deflectors 13, 14 the bristles 17 are pressed together whereby the volume between the bristles is being reduced.
- air is being expelled from the brushes 3, 4, which air is guided along the walls 18 of the housing 2.
- the bending by the deflectors 13, 14 of the brushes 3, 4 is for example 5 mm while the surface to be cleaned 16 bends the brushes 3, 4 for example only 3 mm.
- the deflectors press against the bristles of the brush at a location before the location where the bristles contact the surface to be cleaned as seen in the direction of rotation.
- Fig. 4B shows a graph whereby the volume between the bristles 17 is indicated at different angles ⁇ .
- air is blowing in the direction indicated by arrow P8 along the walls 18 of the housing 2.
- the cleaning device 1 can be used for cleaning soft surfaces with carpet and hard surfaces. It can be used by only rotating the brushes 3, 4 but the cleaning can be supported by sucking vacuum by means of vacuum device in the entrance 12. Furthermore the device 1 can be used for wet cleaning of for example hard surfaces whereby water or a cleaning liquid is guided from the container 9 towards the brushes 3, 4 and the surface 16 is being wetted by the brushes 3, 4. It is also possible to spray water on the surface by means of a separate device in which case the cleaning device need not to be provided with a container 9. It is important that as little as possible water or cleaning liquid remains on the surface 16. The water or cleaning liquid will be removed by the brushes 3, 4 and guided into the entrance 12 towards the debris collecting chamber 11. As can be seen in fig.
- the deflectors 13, 14 form part of a bottom plate 21 as indicated in Fig. 5B .
- the bottom plate 21 can be made from flexible plastic being easily bendable.
- the bottom plate 21 comprises side edges 22, whereby the distance between opposite side-edges 22 is shorter than the length of the brush 3,4. Water droplets 19 will either be guided by the side edges 22 of the bottom plate 21 towards a V-shaped nose 23 from which the droplets 19 will fall between the brushes 3, 4 and will be picked up by the brushes 3, 4 during a next passage of the brushes 3, 4 or the droplets will be picked up by the brushes when moving towards the V-shaped nose 23.
- the V-shaped nose 23 can also be another kind of protruding element.
- Fig. 6 shows a bottom view of another embodiment of the cleaning device 31 according to the invention whereby each deflector 13, 14 is connected to a carrier 32, 33 respectively.
