    Abstract

    A cleaning device has a housing and a handle connected to the housing, with which the housing is moveable by hand with its underside over a floor. A brush roller is mounted in the housing so as to rotate and to be electrically rotatably drivable. The brush roller rests with a brush structure on the floor and the rotating brush roller picks up dirt particles with its brush structure as it passes over. A receiving compartment for dirt particles, which is arranged in the housing along the brush roller. A direction of rotation of the brush roller is towards the receiving compartment, so that dirt particles picked up from the floor by the brush roller are conveyed into the receiving compartment.

    Description

    BRIEF DESCRIPTION OF THE FIGURES

    [0032] FIG. 1 shows an exemplary cleaning device according to the invention in its functional position;

    [0033] FIG. 2 shows the cleaning device of FIG. 1 with a housing having two housing parts before the connection of the housing parts; and

    [0034] FIG. 3 shows the cleaning device in the assembled state of the two housing parts.

    DETAILED DESCRIPTION OF THE INVENTION

    [0035] Referring now to the figures of the drawing in detail and first, in particular, to FIG. 1 thereof, there is shown an exemplary cleaning device 1 according to the invention with a handle 2 and with a flat, floor-side and rectangular housing 3 connected to it. The housing 3 can be pushed by a person with the handle 2 over a floor 4 with dirt particles 5, for example in the direction of the arrow 6. The housing 3 contains a brush roller 7 with an electric rotary drive. The electric rotary drive can be switched by means of a foot switch 8 on the top of the housing 3. When the device passes over the dirt particles 5, the rotating brush roller 7 picks up the dirt particles 5.

    [0036] The function of the cleaning device 1 and its design are explained in greater detail in the enlarged views shown in FIG. 2 and FIG. 3:

    [0037] FIG. 2 shows that the housing 3 has two housing parts 9, 15 that can be plugged to one another. A first housing part 9 has a base plate 10 and forms part of the lower wall of the housing 3. A universal joint 11 is arranged centrally on the base plate 10 as a connection to the handle 2. This allows the base plate 10, which rests on the floor 4, to be moved by hand in any direction, as indicated by the arrows 12. The handle 2 is obviously composed of several longitudinal parts that are plugged together, but this does not necessarily have to be the case. The handle 2 may also be telescopingly length-adjustable.

    [0038] In FIG. 2, a wiping cloth 13 covering the base plate 10 is attached to the underside of the base plate 10, which overlaps the base plate 10 from below with two opposite edge regions 14a, 14b and is detachably held there by means of holding elements (not shown in detail). The first housing part 9 with a wiping cloth 13 on the base plate 10 can be used separately as a cleaning device without the second housing part 15. Likewise, the combination of first housing part and second housing part can be used both with wiping cloth 13 and without wiping cloth 13 as a cleaning device.

    [0039] The second housing part 15 is designed as a cover shell part 16 that can be detachably attached to the base plate 10. For this purpose, an indentation 18 is cut out in the area of the universal joint 11 in the cover shell part 16 for free access of the universal joint 11 and simple lateral attachment of the cover shell part 16. The detachable plug-in connection is implemented here, for example, by four pins 17 projecting downwards from the cover shell part 16 and the corresponding counter receptacle 19 on the base plate 10.

    [0040] As can be clearly seen from FIGS. 2 and 3, the brush roller 7 is arranged in a lateral edge region (shell edge region) of the cover shell part 16 and extends over the length of the longer rectangular side of the cover shell part 16. In particular, it can be seen from FIG. 2 that the cover shell part 16 covers the comparatively smaller base plate 10 and projects or engages over the base plate 10 with the brush roller 7 in such a way that the brush roller 7 comes to lie next to the base plate 10. This means that the underside of the base plate 10 and the brush roller 7 are essentially flush with the floor 4.

    [0041] The brush roller 7 is covered by a shell edge region 20 with a gap distance. The shell edge region 20 is guided downward to such an extent that a floor gap 21 remains between floor 4 and shell edge region 20. The gap width of the floor gap 21 is for example selected to be as large as the maximum diameter of dirt particles to be picked up by the cleaning device 1.

    [0042] The shell edge region 20 partially covering the brush roller 7 is made of transparent material so that the rotating brush roller 7 and its function are visible.

    [0043] In FIG. 3, the arrow 22 indicates the direction of rotation of the brush roller 7, whereby it is evident that dirt particles are picked up and transported upwards into a receiving compartment 23 in the manner of a drawer compartment. FIG. 3 shows the receiving compartment 23 in a partially extended position. For emptying, the receiving compartment 23 can be pulled out completely.

    [0044] The receiving compartment 23 is arranged downstream of the brush roller 7 and has a roller-remote longitudinal sidewall 24 and a roller-near longitudinal sidewall 25. The roller-remote longitudinal sidewall 24 is obviously higher than the roller-near longitudinal sidewall 25. In the inserted state of the receiving compartment 23, the roller-remote longitudinal sidewall is in contact with the underside of the upper wall of the cover shell part 16. The roller-near longitudinal sidewall 25 is comparatively lower and, in the inserted state of the drawer compartment 23, forms a feeding gap 26 for conveyed dirt particles between the underside of the top wall of the cover shell part 16 and the longitudinal sidewall 25 near the roll.

    [0045] FIG. 3 shows an example of a preferred brush structure 27 on the circumference of the brush roller 7 consisting of elastic ribs and lamellae. The brush structure 27 can be formed from elastic lamellae 28, 28a, which are spaced apart in circumferential direction of the brush roller 10, project from the brush roller 10 and are set obliquely in circumferential direction towards the longitudinal centre of the roller. Elastic, spaced-apart longitudinal ribs 29 are arranged between the elastic lamellae 28a, 28b.
