Description

Field of the invention

[0001] The invention relates to a cleaning device comprising a wiping plate having a first main side and a second main side, wherein the first main side corresponds to a cleaning cloth which is fixed on the wiping plate in an exchangeable manner or can be fixed on the wiping plate. BACKGROUND

[0002] Such cleaning devices are widely known and are used both for wet cleaning of smooth floors, such as tile floors or parquet floors, and for dry cleaning of smooth floors. In the case of the design of the cleaning device for dry cleaning, it is mostly used for intermediate cleaning and dusting. For this purpose, a cleaning cloth is fixed on the wiping plate, which is removed again or replaced by a new cleaning cloth after the cleaning work has been completed or after the dirt saturation. It is known in this respect that the cleaning cloth is constructed from a non-woven fabric and is fixed on the wiping plate by means of simple fixing means, such as by means of a soft clip.

[0003] According to an advantageous design, the cleaning device is constructed for dry cleaning. For this purpose, the cleaning device with the fixed cleaning cloth is guided over the floor to be cleaned, wherein the cleaning cloth receives dust and smaller particles from the floor to be cleaned. In this case, it is possible to receive dusty dirt into the base body of the cleaning cloth, wherein the receiving capacity for such dirt is excellent when the material of the cleaning cloth is porous, such as in the case of a non-woven fabric. The problem in this case is that the cleaning cloth cannot receive larger particles and these remain on the floor to be cleaned. SUMMARY

[0004] It is an object of the invention to provide a cleaning device which is constructed to receive larger particles.

[0005] The invention achieves the above-mentioned object by the features of claim 1. Advantageous design proposals are indicated in the dependent claims.

[0006] In order to achieve the above-mentioned object, the cleaning device comprises a wiping plate having a first main side and a second main side, wherein the first main side corresponds to a cleaning cloth which is fixed on the wiping plate in an exchangeable manner or can be fixed on the wiping plate, the wiping plate has a storage portion for receiving dirt particles, and the cleaning cloth forms a delimiting wall of the storage portion.

[0007] According to the application, the cleaning cloth has two functional sides. The first functional side faces the floor to be cleaned during regular use. Depending on the design of the cleaning cloth, this cleaning cloth receives dust and smaller particles during the cleaning operation. Larger particles are transported to a storage in the wiping plate, wherein the particles accumulate on the second side of the cleaning cloth, since the second side of the cleaning cloth constitutes the delimiting wall of the storage, which constitutes the bottom side of the storage, since the cleaning cloth is arranged on the first main side. In this design, the dirt can be removed particularly easily. The dust and smaller particles adhere on one side of the cleaning cloth, while the larger particles adhere on the other side of the cleaning cloth. In order to remove the particles, the cleaning cloth is removed from the wiping plate, either the cleaning cloth can be disposed of together with the received dirt or the cleaning cloth can be transported to a cleaning device, for example a washing device.

[0008] The receiving opening can be configured by the storage. Via the receiving opening, the dirt particles can be transported to the storage.

[0009] The receiving opening can open into the edge of the wiping plate. In this way, the receiving opening is particularly easy to access and the dirt particles can be reliably received into the storage.

[0010] Preferably, the wiping plate is configured rectangularly, wherein the receiving opening corresponds to the narrow side of the wiping plate. This makes the cleaning cloth particularly easy to fasten on the one hand. On the other hand, the receiving opening is accessible even in the case of a taut cleaning cloth and does not cause any interference during the wiping process.

[0011] The receiving opening can correspond to a sweeping device. Via the sweeping device, the dirt particles can be more easily received into the storage. The sweeping device can comprise, for example, a rotatable brush, which can be brought to bear against the floor to be cleaned and which transports the particles from the floor to be cleaned into the storage. Here, as with the receiving opening, the sweeping device preferably corresponds to the narrow side of the wiping plate.

[0012] In order to configure the storage, a recess can be introduced into the wiping plate, wherein the recess opens towards the first main side. In this way, it is ensured that the cleaning cloth constitutes the delimiting wall of the storage. Furthermore, the wiping plate can be particularly easy to manufacture, wherein the wiping plate can be configured, for example, from plastic and manufactured by means of injection molding.

[0013] On the second main side, a handle can be hingedly fastened. Here, the hinge is preferably configured as a universal joint, which enables the cleaning device to be moved extremely well by means of the handle. The hinged joint of the handle is preferably configured in such a way that the handle can be turned through a certain angle and the handle is oriented parallel to the surface to be cleaned. In this way, the cleaning device can also reach difficult-to-reach areas, for example, under furniture.

[0014] The cleaning cloth can be constructed from a textile sheet. Such a cleaning cloth is inexpensive and easy to manufacture. Depending on the design, the cleaning cloth can be constructed for single use or for repeated use. If the cleaning cloth is constructed for repeated use, this cleaning cloth is preferably designed to be deliverable to a washing device.

[0015] The cleaning cloth is preferably constructed from a non-woven cloth. In this design, the cleaning cloth is constructed as a disposable cloth and is disposed of together with the received dirt after use. BRIEF DESCRIPTION OF DRAWINGS

[0031] The attached figure shows a cleaning device 1 in the form of a flat wiping device for dry cleaning. The cleaning device 1 includes a wiping plate 2 having a first main side 3 and a second main side 4. The wiping plate 2 is constructed in a rectangular shape and has two longitudinal sides 20, 21 and two narrow sides 10, 22. A circumferential edge 9 is provided between the first main side 3 and the second main side 4. The wiping plate 2 is constructed of injection-moldable plastic.

[0032] The first main side 3 of the wiping plate 2 corresponds to the cleaning cloth 5, which covers the first main side 3 and extends around the two longitudinal sides 20 and 21 to the second main side 4. In this design, the cleaning cloth 5 is constructed as a textile sheet made of non-woven fabric. To secure the cleaning cloth 5, a fixing element 30 in the form of a soft clip is arranged on the second main side 4 of the wiping plate 2. The fixing element 30 is arranged in the corner area of ​​the wiping plate 2.

[0033] The wiping plate 2 corresponds to the storage section 6 for receiving dirt particles. To construct the storage section 6, a recess 12 is introduced into the wiping plate 2, which opens towards the first main side 3. In this way, the cleaning cloth 5 forms the dividing wall 7 of the storage section 6. During normal use, the cleaning cloth 5 is positioned below the wiping plate 2, thus dirt particles received in the storage section 6 accumulate on the cleaning cloth 5. After removing the cleaning cloth 5, the dirt particles can be disposed of without damage, for example, by folding the cleaning cloth 5.

[0034] To receive dirt particles into the storage section 6, the storage section 6 is equipped with a receiving port 8, which leads to the edge 9 of the wiping plate 2 located on the narrow side 10. In the illustrated embodiment, the receiving port 8 is located in the area of ​​the edge 9 between the wiping plate 2 and the cleaning device 11.

[0035] On the second main side 4 of the wiping plate 2, a handle 13 is fixed in a hinged manner by means of a universal joint 23. The universal joint 23 is configured in such a way that the handle 13 can be tilted to a certain extent during the cleaning operation, so that the handle 13 lies flat on the wiping plate 2 and is oriented substantially parallel to the floor to be cleaned.

[0036] The receiving opening 8 corresponds to a cleaning device 11. The cleaning device 11 is arranged on the narrow side 10 of the wiping plate 2, like the receiving opening 8. The cleaning device 11 is fixed on the wiping plate 2 in such a way that it can be moved between a cleaning position 14 and a rest position 15. The cleaning device 11 has a rotatably supported cleaning element 16, which is configured as a cleaning roller and contacts the floor to be cleaned in the cleaning position 14. In the exemplary design shown, the cleaning element 16 is configured from a resilient foam material.

[0037] In order to set the cleaning element 16 in rotation, the cleaning device 11 is provided with a drive device in the form of a drive wheel 24. The drive wheel 24 is configured as a friction wheel. If the cleaning device 11 is located in the cleaning position 14, the drive wheel 24 lies against the floor to be cleaned (or another surface to be cleaned). The drive wheel 24 is at least constructed on the outer circumferential side from an elastomer material and lies against the floor to be cleaned by a pretensioning force. However, other suitable materials can also be used for the drive wheel 24. If the cleaning device 1 is moved past the narrow side 10, the drive wheel 24 is set in motion and in turn drives the cleaning element 16. In this case, the rotational speed of the cleaning element 16 is determined by a transmission stage 25 arranged between the drive wheel 24 and the cleaning element 16.

[0038] The cleaning device 11 is also provided with a receiving ramp 26, which leads to a cleaning lip 27. The receiving ramp allows particularly efficient receipt and transport of dirt to the storage 6. The cleaning lip 27 faces the floor to be cleaned in the cleaning position 14. The receiving ramp 26 and the cleaning element 16 are at least partially configured congruently, and there is only a narrow gap between the cleaning element 16 and the receiving ramp 26. The gap ultimately leads to the receiving opening 8 of the storage 6.

[0039] In the rest position 15, the cleaning element 16 is spaced apart from the floor to be cleaned. In the rest position 15, the cleaning element 16 is partially retracted into the wiping plate 2. On the second main side 4 of the wiping plate 2, a cover 28 is arranged, which covers the cleaning device 11.

[0040] The wiping plate 2 corresponds to a handling device 17, which is functionally connected to the cleaning device 11, wherein, by means of a handling of the handling device 17, the cleaning device 11 is moved from the rest position 15 into the cleaning position 14 and vice versa. For this purpose, the handling device 17 is equipped with a foot plate 18. The handling device 17 is also equipped with a spring element 19, which, after a handling of the handling device 17, causes the cleaning device 11 to be moved automatically from the rest position 15 into the cleaning position 14. By pressing the foot plate 18 into the wiping plate 2, the handling device 17 is unlocked, and the spring element 19 causes the cleaning device 11 to be moved from the rest position 15 into the cleaning position 14. In this case, the foot plate 18 is pivoted away from the wiping plate 2 and remains in a flipped-up position in the cleaning position 14. In order to move the cleaning device 11 from the cleaning position 14 back into the rest position 15, the foot plate 18 is flipped back towards the wiping plate 2, wherein the cleaning device 11 is moved from the cleaning position 14 into the rest position 15 against the force of the spring element 19.

[0041] Figure 1 is a sectional view of the cleaning device 1 described above. It can be seen that the storage 6 is realized by means of a recess 12 introduced into the first main side 3 of the wiping plate 2. The cleaning cloth 5 constitutes a delimiting wall 7 of the storage 6 by means of the side facing the wiping plate 2.

[0042] Figure 2 is a perspective view of the cleaning device 1. In the design variant shown in Figure 2 , the cleaning device 1 has its cleaning device 11 in the rest position 15 and partially retracted into the wiping plate 2. If the cleaning device 11 is in the rest position, the cleaning device 1 can be guided over the floor to be cleaned.

[0043] Figure 3 is a perspective view of the cleaning device 1, wherein the cleaning device 11 is in the cleaning position 14. In this position, the cleaning element 16 and the cleaning lip 27 contact the floor to be cleaned. The foot plate 18 of the handling device 17 extends from the wiping plate 2.

[0044] Figure 4 and Figure 5 are sectional views of the cleaning device 1 in Figure 3 . In Figure 4 , the section plane is chosen in such a way that the cleaning element 16 is recognizable, whereas in Figure 5 , the section plane extends through the drive wheel.

[0045] In Figure 4 and Figure 5It can also be seen that the pedal 18 is configured as a single-arm lever which can be pivoted about a pivot axis 51. In the embodiment shown, the pedal 18 is provided with a press-to-lock device (Druck-Druck-Verriegelung) 50. A single press of the pedal 18 downwards in the region of the free end of the pedal 18 effects the unlocking. If the pedal 18 is then flipped back down again, the pedal 18 is locked by a further press.

[0046] The pedal 18 is connected to a holding body 53 by means of a diagonal strut 52, which can be moved linearly in a guide device 54 which is arranged on the wiping plate 2. The guide device 54 comprises two grooves which are configured in the wiping plate on both sides of the holding body 53. By means of this, the pivoting movement of the pedal 18 is converted into a translational movement of the holding body 53, which can be moved back and forth in the guide device 54 as a result of the pedal. The diagonal strut 52 is connected to the lever 18 in such a way that it can be moved about a pivot axis 55. On the holding body 53, one end of a spring element 19 is also fixed, in order to move the lever 18 away from the wiping plate 2 after the unlocking of the locking device 50 and to bring the cleaning device 11 into the cleaning position 15. The other end of the spring element 19 is fixed on the wiping plate 2.

[0047] Figure 6 The cleaning device 1 is shown in Figure 2 . The cleaning device 1 is shown in

[0048] Figure 7 The cleaning device 1 is shown, the cleaning device 11 being in the cleaning position. In this case, the pedal 18 is in the flipped-up position. As a result of this, the holding body 53 is moved in the guide device 54 towards the first narrow side 10. This movement is transmitted to the cleaning device 11 by means of the actuating member 57 which is configured as a lever. This movement takes place under the action of the spring 19 which is connected to the pedal 18 by means of the holding body 53.

[0049] From Figure 7 It can also be seen that the cleaning device 11 comprises a movable body 60 which is configured as a movable slide. In this case, the cleaning device 11 corresponds to a slide guide 61 which is arranged on the wiping plate 2. The slide guide 61 comprises guide elements 62 which are arranged on both sides of the movable body 60 and each have a guide slot 63. On both sides of the movable body 60, guide cams 64 are arranged (cf. Figure 8) into the guide slot 63. The slide guide 61 is configured in such a way that the movement of the cleaning device 11 along the wiping plate 2 is effected. Here, the cleaning device 11 is caused to project laterally beyond the narrow side 10 of the wiping plate 2 in the cleaning position 14, while the cleaning device does not project beyond the edge of the wiping plate 2 in the rest position 15 (cf. Fig. 1). Figure 2 To this end, the guide slot 63 has a first section 65 which extends parallel to the plane of the wiping plate 2. In Figure 12 This can also be seen clearly in Fig. 4, which is a partial view of the wiping plate 2 with the slide guide 61, but without the cleaning device 11.

[0050] The slide guide 61 is also configured in such a way that the movement of the cleaning device 11 transversely to the wiping plate 2 is effected, so that the cleaning device 11 projects beyond the first main side 3 of the wiping plate 2 in the cleaning position 14. This is effected in that the guide slot 63 of the slide guide 61 has a second section 66 which extends transversely to the plane of the wiping plate 2 from the section 65 towards the first main side 3. The section 66 is arranged on the side of the section 65 which faces the narrow side 10.

[0051] The slide guide 61 also has a third section 67 of the guide slot 63 in which the guide slot 63 extends transversely to the plane of the wiping plate 2. The section 67 is arranged on the side of the section 65 which faces away from the narrow side 10. The third section 67 makes it possible for the cleaning device to be moved towards the wiping plate 2, so that the cleaning device is partly received in a recess configured in the wiping plate 2 in the rest position 15.

[0052] Figure 8 to Figure 10 Further details of the cleaning device 11 are shown. Figure 8 The cleaning device 11 is shown with the cover portion 28, while in Figure 9 the cleaning device 11 is shown without the cover portion, in order to show more clearly the drive wheel 24 configured as a friction wheel, the cleaning element 16 configured as a cleaning roller, and the transmission stage 25.

[0053] As shown, the cleaning device 11 has a drive wheel suspension 71 which is arranged on the wiping plate 2 in such a way that it can move about a first pivot axis 72.

[0054] The cleaning device 11 also comprises a cleaning element suspension 73 which is arranged on the wiping plate 2 in such a way that it can move about a second pivot axis 74. In the embodiment shown, the first pivot axis 72 and the second pivot axis 74 are arranged coaxially.

[0055] The drive wheel suspension 71 comprises a spring 75 which pre-tensions the drive wheel 24 towards the surface to be cleaned. The cleaning element suspension 73 comprises a spring 76 which pre-tensions the cleaning roller 16 towards the surface to be cleaned. The drive wheel suspension 71 and the cleaning element suspension 73 are independent of one another, so that the cleaning element 16 and the drive wheel 24 can be pivoted independently of one another about the first pivot axis 72 or the second pivot axis 74.

[0056] Figure 9 It is shown how the cleaning element 16 can be brought into rotational movement by the drive wheel 24 by means of the transmission stage 25. During the movement of the wiping plate 2 along the surface to be cleaned, the drive wheel 24 can be brought into rotation by contact with the surface to be cleaned. For this purpose, the transmission stage 25 is provided. This transmission stage has a transmission wheel 81 which can be rotated about a transmission rotation axis 80. The transmission rotation axis 80 is arranged coaxially to the first pivot axis 72 and the second pivot axis 74. The transmission wheel 81 comprises a first toothing 82 and a second toothing 83. The first toothing 82 meshes with a drive wheel toothing 84 provided on the drive wheel 24. The second toothing 83 meshes with a cleaning element toothing 85 provided on the cleaning element 16. By means of this, the rotational movement of the drive wheel 24 can be converted into a rotational movement of the cleaning element 16. In this case, a transmission ratio is achieved by means of the transmission stage 25, so that the rotational speed of the rotatable cleaning element 16 differs from the rotational speed of the drive wheel 24. In the example shown, the rotational speed of the cleaning element 16 is greater than the rotational speed of the drive wheel 24. This is achieved in that the number of teeth of the first toothing 82 is smaller than the number of teeth of the drive wheel toothing 84, and the number of teeth of the second toothing 83 is greater than the number of teeth of the cleaning element toothing 85.

[0057] Figure 10 A plan view of the cleaning device 11 is shown. Here, it can be clearly seen how the cleaning lip 27 is arranged along the cleaning element 16.

[0058] Figure 11 The cleaning device 11 and the tread plate 18 are shown, other elements of the cleaning device being omitted here. The figure also shows by which elements the movement of the tread plate 18 is transmitted to the cleaning device 11. In particular, it can be seen that the holding body 53 is connected to the slider of the cleaning device 11 for this purpose by means of the lever-shaped actuating member 57. Figure 11 The arrangement of the spring element 19 is also shown, one end of the spring element being fixed to the holding body 53.

[0059] Figure 12 The wiping plate 2 without the cleaning device 11 is shown. Here, it can be clearly seen that the slot guide 61 for the cleaning device 11. Figure 12 The storage 6 constructed in the wiping plate 2 is also shown.

[0060] In addition to the cross section of the cleaning element 16 being shown, Figure 13The arrangement of the cleaning lip 27 corresponding to the cleaning element 16 is also shown. The cleaning element suspension 73 comprising the attached spring 76 is also shown.

[0061] From Figure 13 It can also be seen that the cleaning device 11 has a scraper 90 which abuts against the cleaning element 16. By means of this scraper it is possible to detach dirt which has adhered to the cleaning element 16, so that these can be collected in the storage 6. The scraper 90 is arranged tangentially to the roller-like cleaning element 16.
