Cleaning tool for picking up dirt from a floor surface

The invention relates to a cleaning tool for picking up dirt from a floor surface, which by means of a on his Housing articulated guide rod is reciprocable and one driven by the reciprocating movement Brush roller as well as on both longitudinal sides of the brush roller arranged dirt collecting spaces in which the from The dirt particles thrown up by the roller brush have been caught.

Such cleaning tools are generally known from cleaning devices on the market. From time to time With these cleaning tools, the time has to be spent in the dirt collecting rooms any accumulated dirt is removed. This is relatively cumbersome and, above all, unsanitary because of the any accumulated dirt must be emptied freely into a waste container.

The invention is based on the object of designing a cleaning tool of the type described at the outset so that the accumulated dirt can be removed from the dirt collecting spaces in a simple and hygienic manner.

The object is achieved according to the invention in that a suction nozzle is hinged to the housing, which can be connected to a suction pipe connected or connectable to a vacuum cleaner, that furthermore in the ground the dirt collection spaces suction openings are provided, the are covered by closing elements that open under the action of the suction air flow generated by the vacuum cleaner. For emptying the dust collection rooms, the cleaning tool is briefly connected to a vacuum cleaner and

as a result, the accumulated dirt is sucked out of the dirt collecting spaces. The closure elements are opened by the suction air flow opened so that the air flow can sweep through the collecting spaces and carry away the accumulated dirt. 5

A cleaning tool designed in this way can, however, also be connected to a vacuum cleaner during the cleaning process itself will. In particular, this can improve the cleaning effect of less powerful vacuum cleaners because dirt that was loosened by the roller brush, but not thrown up, by the suction air flow is captured and sucked in. If only small cleaning processes are to be carried out, the cleaning tool can be used alone work without a vacuum cleaner.

The locking elements are included so that the dirt in the collecting spaces cannot fall out unintentionally If the suction air flow is not present, it is automatically brought into the position closing the suction opening by the action of force. A structurally particularly simple solution for closing the suction opening consists in that as closing elements pivotably arranged flaps are provided. It is advantageous that the flaps by spring force are pivoted into the position closing the suction opening.

The fact that as a closure element in each collecting space one in the vertical direction from the suction openings Removable cover strip is provided, the air flow at the suction openings is approximately horizontal on both sides directed into the respective collecting room. This has the • advantage that the deposited on the floor of the collecting rooms Dirt is whirled up and carried away by the air flow.

For using the cleaning tool as a vacuum cleaner nozzle it is particularly advantageous if the suction openings extend over the entire width of the floor

extending slots are formed. The dirt can be easily picked up through such slots.

The subject of the application is explained in more detail below using an exemplary embodiment shown in the drawing described.

1 with the housing of a cleaning tool is referred to, on the upper side of which a suction nozzle 2 is pivotably articulated is. In the suction nozzle 2 can be connected to a vacuum cleaner or connectable to a vacuum cleaner Intake pipe 3 can be inserted. By means of this suction pipe 3, the cleaning tool can be placed on the floor surface to be cleaned be moved back and forth.

In the housing 1, a brush roller 4 is rotatably arranged, which is arranged on the housing when moving back and forth Impellers, which transmit their rotational movement to the brush roller 4, is driven. The roller brush 4 rotates between itself from the underside of the cleaning tool to approximately the height of the axis of rotation 5 of the brush roller 4 upwardly extending guide surfaces 6. The dirt particles are from the brush roller 4 on these Guide surfaces 6 guided along and formed over the guide surfaces in the two longitudinal sides of the brush roller 4 Dust collection rooms 7 thrown. In the floor 8 of the dust collection rooms 7, designed as slots 9, suction openings are provided which are covered by pivotable flaps 10. The flaps 10 can be pivoted into their position closing the slots 9 by gravity alone.

In order to ensure the closure of the slots in any position of the cleaning tool, it is advantageous to use the To hold flaps 10 in the closed position by spring force. The spring force is dimensioned so that that of the vacuum cleaner The suction air generated swivel the flaps IO away from the slot 5 can.

If the cleaning tool is connected to a vacuum cleaner, then the flaps 10 are activated by the suction air flow pivoted upwards so that the air is sucked in through the suction openings 9. This is done in the dust collection rooms 7 carried away accumulated dirt and transported to the vacuum cleaner. Is the cleaning tool already connected to a vacuum cleaner during a cleaning process, then the cleaning effect of the suction air supported by the roller brush, since the only loosened, but not taken up by the roller brush Dirt can be carried away by the airflow.

Instead of the pivotably arranged flaps 10, vertically displaceable cover strips can also be provided. Such cover strips are each pressed downward against the suction openings by spring force. Through the suction air flow of the connected vacuum cleaner, the cover strips are raised so that the air enters the suction openings 9 can occur.
