Description

[0001] Device for wringing out a cleaning cloth and cleaning bucket with such a

[0002] The invention relates to a device for wringing out a wiping cloth, in particular a lid for a mop bucket, as well as a mop bucket with such a device for wringing out a wiping cloth according to the preamble of the independent patent claims.

[0003] Technological background

[0004] Numerous mopping systems are available for cleaning floors in apartments and houses. These typically consist of a fluid container for holding water mixed with cleaning agent, a mop with a mop cloth or mop elements attached to the mop, and a wringing element for the mop. To mop a floor, the mop is immersed in the water mixed with cleaning agent, dehumidified with the wringing element, and then the floor is cleaned with the residual moisture remaining in the mop cloth.

[0005] The disadvantage of this well-known mopping system, however, is that the mop is rinsed again in the water in the reservoir after cleaning, which causes the water to become dirty over time. This reduces cleaning performance. Furthermore, it is also disadvantageous from a hygienic point of view to immerse the mop in the water, which contains the dirt and contaminants it has picked up.

[0006] In order to achieve a good cleaning result with such a wiping system, the cleaning water must be changed frequently, which is not only time-consuming but also not particularly sustainable, since additional cleaning agent is required with each change of the cleaning water.

[0007] Alternatively, with such a system, it may be necessary to replace the wiping cloth during a cleaning process because the wiping cloth becomes so dirty that sufficient cleaning performance is no longer achieved.

[0008] Wiping systems are known from the prior art in which the mop is squeezed or wiped off on a device attached to the mop bucket for wringing out the wiping cloth in order to reduce the moisture content in the wiping cloth.

[0009] For example, a wiping system is known from the prior art in which a holding plate for the wiping cloth has a joint and is folded together and inserted into a slot to wring out the wiping cloth. A disadvantage of such a system, however, is that it requires comparatively high forces to wring out the wiping cloth sufficiently. Furthermore, the wringing forces are highly dependent on the operator, so that a reproducible wringing result with low residual moisture in the wiping cloth cannot be achieved. This can lead to too much moisture being introduced into floor surfaces, particularly wooden or parquet floors, and the floor can suffer long-term damage. Furthermore, wringing the wiping cloth too forcefully can damage the wiping fibers and / or the wringing device, which can reduce the service life of at least one component of the wiping system.

[0010] Furthermore, wiping systems are known in which a mop with a rigid holding plate for a wiping cloth is inserted into a slot and squeezed out against a wiper lip, thereby reducing the moisture content in the wiping cloth. Although such systems offer the advantage over the systems described in the previous section that wringing occurs relatively evenly across the entire length of the wiping cloth, the wringing result here too depends on the force exerted by the operator and / or on the manufacturing tolerances of the system, meaning that a completely satisfactory and reproducible wringing result is still not achieved. Furthermore, in such systems, the fiber of the wiping cloth is generally only loaded in one direction, which leads to uneven wear of the wiping cloth and, consequently, to a deteriorating cleaning result.

[0011] EP 1 219 226 A1 discloses a device for moistening and dehumidifying a wet mop. To set a defined moisture content in the wiper cloth of the wet mop, the wiper cloth is first guided past a moistening nozzle and then moved to a dehumidification device. The dehumidification device has opposing rollers, between which the wet mop is compressed to dehumidify the wiper cloth.

[0012] The disadvantage of such a solution, however, is that it requires an electric drive and thus an additional power supply. Furthermore, the solution proposed in EP 1 219 226 A1 cannot solve the problem of increasing contamination of the cleaning water during the cleaning process.

[0013] Summary of the invention

[0014] The object of the invention is to provide a device for wringing out a wiping cloth which provides a simple and reproducible wringing result and overcomes the disadvantages known from the prior art.

[0015] The problem is solved by a device for wringing out a wiping cloth. The device comprises a frame with a first frame segment, a second frame segment, and a third frame segment, the frame having a first slot in the region of the first frame segment and a second slot in the region of the third frame segment. The frame has a third slot in a second frame segment formed between the first frame segment and the third frame segment, at least one wiping lip being arranged on each of the first and second slots, and at least one further wiping lip being arranged on the third slot in order to wring out a wiping cloth pulled through the respective slot.

[0016] In this context, wringing a mop refers to any process in which the moisture in the mop is reduced by exerting force on the mop, including, in particular, pressing or wiping the mop. Mopping water refers, in particular, to tap water containing a cleaning agent. A mop rinsing liquid refers, in particular, to clear tap water without any additives. Alternatively, the rinsing liquid may also contain additives to facilitate the removal of dirt and grime from the mop.

[0017] The device enables a simple and reproducible wringing result for a mop cloth in a mop system. By splitting the wringing process into multiple slots, contamination of the fresh mop water and the mop cloth can be minimized, enabling particularly efficient cleaning of a floor surface without having to change the mop water in between.

[0018] The additional features listed in the dependent claims enable advantageous improvements and further developments of the device for wringing out a wiping cloth mentioned in the independent claim.

[0019] In an advantageous embodiment of the device, at least two wiper lips are arranged at opposite ends of the third slot to wring out a wiping cloth pulled through the respective slot. This ensures that both an additional wiper lip for wiping after fresh cleaning water has been absorbed and an additional wiper lip for wiping after the wiping cloth has been rinsed in a separate liquid reservoir are possible. This prevents the wiping cloth from coming into contact with a wiper lip that has already become dirty from rinsing after fresh cleaning water has been absorbed. This ensures that the wiping cloth can be wrung out with a particularly low risk of dirt getting into the wiping water.

[0020] In a further advantageous embodiment of the device, the first slot and the second slot are each T-shaped. A T-shaped slot provides space for a fastening element for attaching a handle, as well as for a mop handle arranged on the fastening element. Furthermore, a T-shaped handle ensures that the mop's holding plate, with the mop cloth attached to the holding plate, is inserted correctly into the slot, thus ensuring that the mop cloth is wiped off the wiper lip.

[0021] In a further improvement of the device, the third slot is H-shaped and comprises a fourth slot and a fifth slot. The fourth slot and the fifth slot preferably each form the long sides of the H-shaped slot, which are connected by a shorter central web. An H-shaped third slot can save installation space because the mop can be inserted into the slot in a first orientation and a second orientation. The first orientation is intended for wiping or wringing out the mop after absorbing fresh cleaning water, and the second orientation is intended after rinsing the mop in a rinsing liquid, in particular in clear tap water. The handle is received in the central web of the H-shaped slot, which saves installation space compared to two T-shaped slots.

[0022] In an advantageous embodiment of the device, a pressure element is arranged on each of the slots opposite the wiper lips, in order to press a mop holding plate with a defined pressure force and to wring out the wiping cloth attached to the holding plate. The pressure elements press the holding plate with the wiping cloth against the wiper lip with a defined force, thus achieving a good and consistently reproducible wringing result. Furthermore, the pressure elements enable compensation, allowing the use of wiping cloths of different thicknesses. Furthermore, the pressure elements can be used to compensate for manufacturing tolerances in the holding plate, which also supports a consistent and reproducible wringing result.

[0023] It is preferred if the pressure elements are designed as pressure rollers. Pressure rollers allow for particularly gentle pressing of the holding plate or wiper against the wiper lips. The pressure rollers roll along the holding plate, thereby preventing material removal or scratches on the holding plate.

[0024] It is particularly preferred if the pressing elements are each preloaded by a prestressing element. The contact pressure can be adjusted by prestressing elements. The prestressing elements are preferably completely relaxed when the mop is not inserted into the slot and are prestressed by inserting the holding plate of the mop, whereby a force defined according to a characteristic curve of the prestressing element is established. A prestressing element can in particular be designed in the form of a spring or an elastic element which is prestressed by deformation. In an advantageous embodiment, the prestressing element has a substantially constant characteristic curve in order to press the holding plate against the wiper lip with a constant force defined by the reproducible force in the prestressing element.Alternatively, a pre-tensioning element with a progressive characteristic curve can be used to achieve a higher contact pressure with a thicker wiper cloth.

[0025] In a particularly advantageous embodiment of the device, it is provided that the pre-tensioning elements are designed in the form of elastic rubber elements which, when a holding plate of the mop is inserted into the respective slot, are compressed and thus pre-tensioned by a deflection of the respective pressing element.

[0026] In a preferred embodiment of the device, at least two wiper lips are arranged at different levels on the third slot or on the fourth and fifth slots. The two wiper lips at different levels make it possible to wring out the fibers of the wiping cloth both when the mop handle is pushed down and when it is pulled up, thereby significantly reducing drying time compared to conventional systems. Every movement of the handle therefore contributes to the faster drying process of the fibers of the wiping cloth. In addition, the wiper lips on the two levels ensure that the floor fibers are dried evenly over their entire length and thoroughly cleaned at the same time. Furthermore, the wiper lips on two levels can simultaneously free different areas of the wiping cloth of moisture.This allows for particularly quick and efficient dehumidification of the wiping cloth after absorbing fresh wiping water or rinsing the wiping cloth after the wiping process.

[0027] It is particularly preferred if the two wiper lips in the different planes have different angles relative to a horizontal line. This means that when the mop is inserted into the third slot, the wiping fibers of the wiping cloth are primarily wiped off by the wiper lip in the first plane, and when the mop is pulled out, the wiping fibers are primarily wiped off by the wiper lip in the other plane. This reduces the load on the wiping fibers of the wiping cloth, thereby avoiding, in particular, one-sided loading of the wiping fibers. This reduces wear on the wiping cloth fibers and increases the durability and cleaning effect of the wiping cloth.

[0028] A further improvement to the device provides for the wiper lips in the first plane to have a positive angle relative to the horizontal, while the wiper lips in the second plane have a negative angle relative to the horizontal. These different angles ensure that the wiping fibers are wrung primarily at one wiper lip when the mop is immersed and primarily at the other wiper lip when the mop is withdrawn. This further improves the wringing result and minimizes wear on the wiping fibers.

[0029] In a further preferred embodiment of the device, at least one of the wiper lips arranged on the third slot or on the fourth and fifth slots has a perforation that allows water to pass through the wiper lip. The perforation allows the water escaping from the wiper cloth during wringing to be drained away in a targeted manner, thereby achieving even better drying of the wiper cloth.

[0030] In an advantageous embodiment of the device, it is provided that the wiper lips on the third slot are operatively connected to return lines, which carry away liquid discharged at the wiper lip from the area of ​​the wiper lips.

[0031] A further aspect of the invention relates to a mop bucket with a first chamber for storing mop water, a third chamber separate from the first chamber for storing a liquid for rinsing a mop cloth after a mop operation, and a second chamber arranged or formed between the first chamber and the third chamber, which second chamber is designed to absorb moisture released from the mop cloth during a wringing operation, wherein the mop bucket has a device for wringing out a mop cloth as described in the preceding paragraphs, which device is placed on an opening of the mop bucket or is formed or arranged at least in sections in the mop bucket.Such a mop bucket, in conjunction with the device, enables particularly simple and cost-effective storage of liquids, thus achieving the best possible cleaning results in conjunction with the device for wringing out the mop cloth. This ensures a consistent separation of the fresh mop water and the water used to rinse the mop cloth, minimizing the ingress of dirt into the fresh mop water and thus ensuring excellent cleaning results for as long as possible.

[0043] Detailed description of the invention

[0044] Figure 1 shows a preferred embodiment of a device W according to the invention for wringing out a wiping cloth 140 of a wiping system 100 in a plan view. The device 10 comprises a first frame segment 12, a second frame segment 16, and a third frame segment 14, wherein the first frame segment 12 and the second frame segment 16 are preferably identical. The first frame segment 12, the second frame segment 16, and the third frame segment 14 can be designed either as separate components or as a single component. The frame segments 12, 14, 16 represent a cover plate through which a mop 110 of the wiping system 100 is inserted into a mop bucket 104.The frame construction with the three frame segments 12, 14, 16 is preferably designed to be mirror-symmetrical to a first central axis 66 and mirror-symmetrical to a second central axis 68 to enable mounting of the device 10 on the mop bucket 104 in any orientation. Alternatively, the device 10 may also deviate from mirror symmetry in at least one axis, in which case, correct mounting of the device 10 on the mop bucket 104 is necessary.

[0045] A first slot 42 is formed in the first frame segment 12, into which the mop 110, described in more detail in Figures 6 to 10, can be inserted. The first slot 42 is T-shaped to enable the mop 110, with the handle 116, to be inserted into the first slot 42. A first wiper lip 18 is arranged on the first slot 42 to wipe off a wiping cloth 140 of the mop 110. For this purpose, a holding plate 112 of the mop 110 is pressed against the wiper lip 18 by a first pressure roller 26 such that the wiping cloth 140 is wiped off the first wiper lip 18 and the moisture is wrung out of the wiping cloth 140.The first pressure roller 26 is preloaded by a first spring element 34, so that the holding plate 112 of the mop 110 is pressed against the first wiper lip 18 with a substantially constant force when the mop 110 is inserted into the first slot 42, thus achieving a easily reproducible dehumidification result of the wiping cloth 140. Preferably, as shown in Figure 1, two first pressure rollers 26 are provided, which are arranged on both sides of the T-shaped first slot 42 in order to press the holding plate 112 as evenly as possible against the first wiper lip 18. Below the first slot 42 in the first frame segment 12 is a chamber in which cleaning water mixed with cleaning agent is stored.

[0046] A second slot 44 is formed in the second frame segment 16, into which the mop 110, described in more detail in Figures 6 to 10, can be inserted. The second slot 44 is T-shaped to enable the mop 110, with the handle 116, to be inserted into the second slot 44. A second wiper lip 20 is arranged on the second slot 44 to wipe off a wiping cloth 140 of the mop 110. For this purpose, a holding plate 112 of the mop 110 is pressed against the first wiper lip 18 by a second pressure roller 28 such that the wiping cloth 140 is wiped off the second wiper lip 20 and the moisture is wrung out of the wiping cloth 140.The second pressure roller 28 is preloaded by a second spring element 36, so that the holding plate 112 of the mop 110 is pressed against the second wiper lip 20 with a substantially constant force when the mop 110 is inserted into the second slot 44, thus achieving a easily reproducible dehumidification result for the wiping cloth 140. Preferably, as shown in Figure 1, two second pressure rollers 28 are provided, which are arranged on both sides of the T-shaped second slot 44 in order to press the holding plate 112 as evenly as possible against the second wiper lip 20. Below the second slot 44, a chamber in the second frame segment 14 is located, in which a liquid for rinsing the mop 110, in particular tap water, is stored.

[0047] A third frame segment 14 is arranged or formed between the first frame segment 12 and the second frame segment 16. The third frame segment 14 has an H-shaped third slot 46, on which further wiper lips 22, 23, 24 and 25 are arranged. The H-shaped third slot 46 can be divided into a T-shaped fourth slot 47 and a T-shaped fifth slot 49. The third frame segment 14 represents a drying area in which the wiping cloth 140 is dried and wrung out after being immersed in the wiping water or after being rinsed in the rinsing liquid. The H-shaped third slot 46 is mirror-symmetrical to the first central axis 66.At an end of the H-shaped third slot 46 facing the first frame segment 12, the fourth slot 47 is formed, on which a third wiper lip 22 is arranged to wring out the mop 110 after it has been immersed in the cleaning water. At an end of the H-shaped third slot 46 facing the second frame segment 16, the fifth slot 49 is formed, on which a fifth wiper lip 24 is arranged to wring out the mop 110 after it has been immersed in the liquid to rinse the mop 110. Furthermore, further pressure rollers 30, 32 are provided on a central web 70 of the third frame segment 14 in order to press the holding plate 112 of the mop 110 against the respective wiper lip 22, 24. The further pressure rollers 30, 32 are pre-tensioned via further spring elements 38, 40 in order to exert a substantially constant pressure on the holding plate 112 of the mop 110.

[0048] Figure 2 shows a sectional view of the device 10 for wringing out a mop 140. It can be seen that a first bucket insert 48 for the mop bucket 104 is located below the first frame segment 12, a third bucket insert 50 is located below the third frame segment 14, and a second bucket insert 52 is located below the second frame segment 16. The first bucket insert 48 stores the cleaning water. The second bucket insert 52 stores the liquid for rinsing the mop 110 after the cleaning process. The third bucket insert 50 is empty and serves to collect dripping water released when the mop 140 is wiped off or wrung out.

[0049] Furthermore, Figure 2 shows that a fourth wiper lip 23 is arranged on the third frame segment 14 below the third wiper lip 22. A return line 54, 56 is provided extending from the third and fourth wiper lips 22, 23, respectively, connecting the fourth slot 47 to the first bucket insert 48, so that the wiping water separated from the wiping cloth 140 at the third wiper lip 22 or the fourth wiper lip 23 is returned to the first bucket insert 48.

[0050] Furthermore, Figure 2 shows that a sixth wiper lip 25 is arranged on the third frame segment 14 below the fifth wiper lip 24. A return line 58, 60 is provided extending from the fifth and sixth wiper lips 24, 25, respectively, connecting the fifth slot 49 to the second bucket insert 52 in order to return the liquid discharged from the wiping cloth 140 at the fifth wiper lip 24 or the sixth wiper lip 25 to the second bucket insert 52 for rinsing the mop 110.

[0051] The arrangement of the third, fourth, fifth, and sixth wiper lips 22, 23, 24, 25 allows the fibers of the wiping cloth 140 to be dried both when inserting / pressing down the mop 110 and when pulling out / pulling up the mop 110. This significantly shortens the drying time compared to prior art wiping systems, since in prior art wiping systems, wringing only occurs when inserting the mop 110 into the slot, thus requiring more strokes to achieve a sufficient drying result for the wiping cloth 140. Thus, each movement of the handle 116 of the mop 110 contributes to the drying process of the fibers of the wiping cloth 140. In addition, the geometry of the wiper lips 22, 23, 24, 25 on the two levels of the second frame segment 14 ensures that the fibers of the wiping cloth 140 are dried and cleaned more quickly.The wiper lips are aligned at an angle of 10° to 25°, preferably 14° - 19° to the horizontal.

[0052] In the third frame segment 14, the wiper lips 22, 23, 24, 25 ensure that the floor fibers of the wiping cloth 140 are dried. Furthermore, the wiper lips 22, 23, 24, 25 ensure that the floor fibers are cleaned after immersion in the cleaning water or rinsing liquid, where they are also cleaned first. This process is similar in all mop systems. This means that in the mop systems on the market, the drying and cleaning process in the dry area only occurs once per stroke. In the cleaning system according to the invention, there are two drying areas in which this process occurs twice. When the handle 116 is first pushed down and pulled up to dry the floor fibers of the wiping cloth 140, the floor fibers are dried twice in the present mop system 100 because there are two levels of wiper lips 22, 23, 24, 25. The drying process is therefore twice as fast compared to other mop systems.Likewise, the first time the handle is pushed down and raised in the present system, after immersing it in the cleaning water or rinsing liquid, the floor fibers are cleaned twice in the third frame segment 14 due to the two lip levels. This process is repeated twice, thus the floor fibers are cleaned four times in the dry area when the handle 116 of the mop 110 is pushed down and raised twice.

[0053] A further advantage of the special arrangement and design of the wiper lips 22, 23, 24, 25 on two levels is that the fibers of the wiping cloth 140 are brushed, cleaned, and dried in both directions. This combination, together with the double immersion in the water areas, leads to particularly thorough cleaning and drying of the floor fibers. By processing the fibers of the wiping cloth 140 on both sides, the fibers are stressed not only in one fiber direction, but in both fiber directions. This results in less and significantly more even wear of the fibers of the wiping cloth, which leads to an improved cleaning result. The one-sided wear common in other systems is eliminated with this system. The service life of the floor fibers is thus extended. Thanks to the double-level lip system 22, 23, 24, 25, the floor fibers are evenly dry and clean across the entire surface.The third and fifth wiper lips 22, 24 are arranged at a first angle α to the horizontal, and the fourth and sixth wiper lips 23, 25 are arranged at a second angle β to the horizontal. Furthermore, the upper wiper lips, i.e., the third wiper lip 22 and the fifth wiper lip 24, have a perforation so that the fibers of the wiper 140 are even better dewatered and the wiped-off water can be drained away. The wiper lips 22, 24 are preferably perforated throughout. The shape of the perforation can be adapted according to the design and thus vary depending on production.

[0054] Figure 3 shows a mop bucket 104 according to the invention with a lid 102 for a mop system 100. A handle 109 is provided on the mop bucket 104 to facilitate easy transport of the mop system 100. The mop bucket 104 is designed to positively receive the bucket inserts 48, 50, 52 shown in Figure 4. For this purpose, corresponding form-fitting elements 72, 74, 76 are formed on the bucket inserts 48, 50, 52 and on the mop bucket 104 to enable stable and reliable reception of the bucket inserts 48, 50, 52 in the mop bucket 104.

[0055] The mop bucket 104 has a lid 102 in which the device 10 for wringing out the mop cloth 104 is at least partially arranged or which covers the device 10 in order to protect the mechanism of the device and to prevent undesired leakage of mop water from the mop bucket 104. For this purpose, a fastening mechanism 106 is provided on the lid 102 and / or on the bucket 104, via which the lid 102 is connected to the mop bucket 104. The fastening mechanism 106 comprises a tensioning device 108, such as is known, for example, as a closure for hard-shell suitcases. Furthermore, additional handles 107 can be formed on the fastening mechanism 106 to make the mop bucket easier to carry or to reposition during mopping.

[0056] Instead of a lid 102 as shown in Figure 3, which is guided on an inner side of the mop bucket 104, a lid 102 can also be used which projects beyond the edge of the mop bucket 104 and covers the mop bucket 104 from the outside.

[0057] Figure 4 shows a device 10 for wringing out a wiping cloth 140 with inserts 48, 50, 52 for the mop bucket 104, which form the different chambers of the mop bucket 104. The mop bucket 104 is configured to positively receive the bucket inserts 48, 50, 52 shown in Figure 4. For this purpose, corresponding positive-locking elements 72, 74, 76 are formed on the bucket inserts 48, 50, 52 and on the mop bucket 104 to enable stable and reliable reception of the bucket inserts 48, 50, 52 in the mop bucket 104. Furthermore, Figure 4 shows that the first frame segment 12 is arranged on the first bucket insert 48, the second frame segment 16 on the second bucket insert 52, and the third frame segment 14 on the third bucket insert 50. The three bucket inserts 48, 50, 52 form the three chambers of the mop bucket 104.A first chamber 48 is provided for fresh cleaning water, preferably water containing a cleaning solution, a second chamber 52 for rinsing the used mop 110, and a drying chamber 50, which collects the residual water escaping during wringing. After immersion and drying, the floor fiber of the wiping cloth 140 releases the residual water back into the mop bucket 104. The wiping system 100 effectively prevents the spread of dirt on the floor, as the wiping cloth 140 is both rinsed and subsequently additionally cleaned by wiping against the two wiper lips 24, 25. Thus, a optimally cleaned wiping cloth 140 can be immersed again in the fresh cleaning water to achieve maximum cleaning results. This ensures that the floor is always cleaned with clean and fresh floor fibers.

[0058] The three bucket inserts 48, 50, and 52 can be removed individually from the mop bucket 104, allowing for individual handling. This saves additional water because not all bucket inserts need to be completely emptied, and heavy soiling of the fluid used to rinse the mop cloth does not require the additional cleaning water to be changed.

[0059] Figure 5 shows a further sectional view through a wiping system 100. With essentially the same structure as in Figure 2, Figure 5 shows how a mop 110 with a wiping cloth 140 held on the holding plate 112 of the mop 110 is dried after being immersed in one of the two liquid-filled bucket inserts 48, 52. Upon insertion into the fourth slot 47, the holding plate 112 is pressed by the spring elements 38 and the pressure rollers 30 against the wiper lips 22, 23, which free the wiping cloth 140 of the wiping water. The wiping water wiped off the wiper lips 22, 23 is returned to the first bucket insert 48 via the return lines 54, 56. When the mop is inserted into the fifth slot 49, the holding plate 112 is pressed by the spring-loaded pressure rollers 32 against the wiper lips 24, 25, which free the wiping cloth 140 from the liquid for rinsing the wiping cloth 140.The liquid scraped off the scraper lips 24, 25 is returned to the second bucket insert 52 via the return lines 58, 60. Furthermore, the dripping liquid is collected in the third bucket insert 50.

[0060] Figure 6 shows a preferred embodiment of a holding device 150 for a wiping cloth 140. The holding device 150 comprises a holding plate 112 with a first side 118, to which the wiping cloth 140 can be fixed. The first side 118 can also be referred to as the bottom side or underside of the holding plate 112. The holding plate 112 further has a second side 120 opposite the first side 118, on which a fastening element 114 for fastening a handle 116 of a mop 110 to the holding plate 112 is arranged. For this purpose, a receiving element 164 for receiving one end of the handle 116 is formed on the fastening element 114. The second side 120 can also be referred to as the top side of the holding plate 112. A first fixing means 122 is arranged on the first side 118 in order to reversibly and detachably fix the wiping cloth 140 to the holding plate 112.The first fixing means 122 comprises, in particular, a first hook-and-loop fastener 124 for securing the wiping cloth 140 to the first side 118 of the holding plate 112. The first hook-and-loop fastener 124 can, in particular, comprise two or more parallel hook-and-loop strips 126, 128 or a hook-and-loop fastener extending around the holding plate 112 to enable the most stable possible fixation of the wiping cloth 140.

[0061] At least one second fixing means 134, preferably two second fixing means 134, 136, is arranged on the second side 120 of the holding plate 112. These fixing means are designed to fix end sections 130, 132 of the wiping cloth 140, which are folded over a first edge 148 of the holding plate 112 from the first side 118 to the second side 120. The second fixing means 134, 136 each comprise, in particular, a second hook-and-loop fastener 166 and a tensioning element 138, 139, which are arranged on the end regions 152, 154 of the holding plate 112. The tensioning elements 138, 139 each comprise a hinge 160 and a flap 162, which engage in the holding plate 112.

[0062] Figure 6 shows the holding device 150 in a closed state, in which the wiping cloth 140 is received on the holding plate 112 and held in place by the clamping elements 138, 139. Curvatures 168 are formed on the clamping elements 138, 139 to allow the clamping elements 138, 139 to be easily released again.

[0063] The holding plate 112 has a long side 146 and a short side 144. A first edge 148 is formed on the short side 144, over which the wiping cloth 140 is guided from the first side 118 of the holding plate 112 to the second side 120. A second edge 149 is formed on the long side 146, at which the wiping cloth 140 protrudes laterally beyond the first side 118 of the holding plate 112. Grooves 170 are formed on the second side 120 of the holding plate 112, into which insert elements 156 in the form of plastic strips 158 are inserted in order to assist the sliding or rolling of the holding plate 112 when the wiping cloth 140 is wringed out on a corresponding device 110 on a mop bucket 104 and to minimize friction in this area.

[0064] The second fixing means 134, 136 and the insert elements 156 are preferably reversibly detachably attached to the holding plate 112, for example by a screw connection, in order to enable replacement of the elements 134, 136, 156, in order to be able to replace the individual element 134, 136, 156 in the event of damage and to avoid having to replace the entire holding device 150.

[0065] Figure 7 shows the holding device 150 in an open state. It can be seen that the wiping cloth 140 has a retraction area 172 in its end sections 130, 132, in which the wiping cloth 140 has a smaller width. Furthermore, the end sections 130, 132 of the wiping cloth 140 are designed to be free of wiping fibers to enable easy attachment to the second attachment elements 134, 136.

[0066] Figure 8 shows an end region 152 of a holding device 150 for a mop 110 with an open tensioning element 138. This shows how the wiping cloth 140 is secured to the holding plate 112. For securing, the end section 130 of the wiping cloth 140 is folded over the first edge 148 on the holding plate 112, attached to a second hook-and-loop fastener 166 on the second side 120 of the holding plate 112, and secured by the tensioning element 138. Furthermore, Figure 3 shows that the wiping cloth 140 has a draw-in region 172 in its end section 130, in which the width of the wiping cloth 140 is reduced compared to the remaining width of the wiping cloth 140. The area of ​​the indentation 172 is also designed to be free of wiping fibers in order to reduce the thickness of the wiping cloth 140 in the end section 130 and thus to facilitate the fixation to the clamping element 138.

[0067] Figure 9 shows a schematic representation of a holding plate 112 of a holding device 150. It can be seen that first fixing means 122 in the form of a first hook-and-loop fastener 124 are arranged on the first side 118 of the holding plate 112, which faces the floor during wiping, in order to be able to fix the wiping cloth 140 to the holding plate 112. The first fixing means 122 have, in particular, two hook-and-loop strips 126, 128, which run parallel along the long side 146 of the holding plate 112 in order to fix the wiping cloth 140 over the longest possible distance. Alternatively, the first fixing means 122 can also be designed as a frame made of hook-and-loop material surrounding the first side 118 of the holding plate 112 or as a solid surface made of hook-and-loop material.Second fixing means 134, 136 are formed on the second side 120 of the holding plate 112. Each fixing means comprises a tensioning element 138, 139 for receiving the wiping cloth 140 after it has been folded around the first edge 148 on the second hook-and-loop fastener 166 of the holding plate 112 and for securing it in a force-fitting manner. This ensures that the wiping cloth 140 is reliably fixed to the holding plate 112 even under high shear forces, which arise particularly when wringing out or wiping the wiping cloth 140 in the mop bucket.

[0068] Figure 10 shows a mop 110. The mop 110 comprises a holding device 150, a handle 116, and a wiping cloth 140, in particular a microfiber cloth 142, attached to the holding device 150. The handle 116 can be connected to the holding device 150 by a first connecting element 176 formed on the handle 116 and a second connecting element 178 formed on the receiving element 164 by a positive or non-positive connection, for example by a screw connection, a clamp connection, a locking connection, or a snap connection.

[0069] To perform a cleaning operation, the mop 110 is first inserted into the first slot 42 and immersed in the cleaning water stored in the first bucket insert 48. When the mop 110 is pulled out of the first slot 42, the wiping fibers of the wiping cloth 140 are wiped off the first wiper lip 18. The first pressure roller 26 exerts pressure on the holding plate 112, in particular on the insert elements 156 arranged in the grooves 170 of the second side 120 of the holding plate 112. The insert elements roll on the pressure rollers 26 and thus press the fibers of the wiping cloth 140 against the first wiper lip 18.

[0070] The mop 110 is then inserted into the fourth slot 47, whereby the moisture of the wiping cloth 140 is further reduced by wiping against the third wiper lip 22 and the fourth wiper lip 23. Excess water is removed from the wiping cloth and returned to the first bucket insert 48 via the return lines 54, 56. A floor surface can then be mopped in the usual manner. After mopping, the mop is inserted into the second slot 44, whereby the wiping cloth 140, soiled by the wiping process, is cleaned in the liquid for rinsing the wiping cloth 140. Furthermore, any dirt and grime still present in the wiping cloth are wiped off the second wiper lip 20 and discharged into the second bucket insert 52.

[0071] The mop 110 is then inserted into the fifth slot 49, with the liquid for rinsing the mop 110 and any remaining dirt being returned to the second bucket insert 52 via the return lines 58, 60. This means that while the liquid for rinsing the mop 110 becomes dirty as the wiping process progresses, the wiping cloth 140 and the cleaning water stored in the first bucket insert 48 remain largely clean, thus achieving a particularly good cleaning result. Furthermore, frequent changing of the cleaning water is eliminated, as the clean cleaning water and the rinsing liquid always remain separate.
