Abstract
A cleaning device for cleaning a surface, which comprises at least one brush (3,4) rotatable in a rotation direction and movable over the surface to be cleaned and at least one spoiler (14) pressing against the bristles of the brush at a location before the location where the bristles contact the surface to be cleaned.
Description
- 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.
- By such a device which is known from
US-1,694,937 the rotatable brush is being used to aid in the loosening and removal of dirt and foreign material from the surface to be cleaned. To perform the cleaning action the brush is pressed against the floor. Hereby the area between two consecutive bristles of the brush varies during one rotation about the axle of the brush. - As is schematically illustrated in
fig. 1 air will be expelled from the brush in the direction indicated by arrow P1 from the brush when contact is made with the surface to be cleaned. The air will be expelled from 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. However 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. - Another disadvantage of this known device is that drops of water fall back on the surface and need to be removed by a separate wiper.
- It is an object of the invention to provide an improved cleaning device whereby dirt excitation due to an airflow away from the brush and/or dropping of water back tot he surface is easily being prevented.
- This object is achieved by the cleaning device according to the invention in that the cleaning device comprises at least one spoiler pressing against the bristles of the brush at a location before the location where the bristles contact the surface to be cleaned.
- Since the bristles are pressed together by the spoiler air will be pushed out of the area between the bristles. Between the spoiler 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.
- In case that the cleaning device is being used for cleaning a surface with liquid whereby the water or cleaning liquid must be removed from the surface, the spoiler which can be attached to the housing of the cleaning device will also prevent water against the inside of the housing from dripping on the surface. Also water on the outside of the housing will flow in the direction of the spoiler and will be guided back into the brush. The water guided back into the brush by the spoiler will be used again for the cleaning action before moving upwards and away from the surface to be cleaned.
- An embodiment of the cleaning device according to the invention is characterized in that the bristles are indented by the spoiler to an extend that suction between the bristles when losing contact with the spoiler is larger than expellation of air from between the bristles when contacting the surface to be cleaned.
- With such indention of the bristles by the spoiler a net air flow towards to the brush will occur near the surface.
- The axle of the brush is kept at a certain predetermined distance from the floor, 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 indention of the bristles by the spoiler is larger than the indention of the bristles by the surface to be cleaned.
- Also in this situation the net air flow by the brush will be directed towards the brush.
- 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 spoilers are provided pressing against the bristles of the brushes, each spoiler is located on a side of a brush remote from the other brush.
- Due to the two brushes rotating in opposite direction a very effective cleaning operation is obtained since each location on the surface to be cleaned will be contacted by both brushes. Furthermore the dirt will be collected between the brushes and can easily be moved in upwards direction to a debris collecting chamber.
- A further embodiment of the cleaning device is characterized in that the spoiler is adjustable with respect to the brush. In this manner the pressure between the spoiler and the brush can be varied. Moreover one can compensate for possible wear of the bristles.
- To prevent dripping from water near ends of the brush, an embodiment of the cleaning device according to the invention is characterized in that the cleaning device is provided with at least one side spoiler 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 spoiler or on the side spoiler 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.
- The invention will be explained in more detail with reference to the drawings, in which
