Description

[0001] The present invention relates to a wiper arrangement for a self-cleaning and / or self-disinfecting toilet with at least one wiper lip, wherein the at least one wiper lip has at least one wiping edge and has at least one surface area along the at least one wiping edge at least on one side.

[0002] The present invention further relates to a toilet with such a wiper arrangement and a method for cleaning and / or disinfecting a toilet seat of such a toilet.

[0003] A squeegee blade is a common component of cleaning tools such as window squeegees. These cleaning tools may also be called scrapers, rubber scrapers, squeegees, or window squeegees.

[0004] Wiper assemblies with a wiping lip, such as window squeegees, may also include other cleaning components such as brushes or sponges.

[0005] A sponge, for example, can be used to spread cleaning fluid on a surface. A brush, on the other hand, can be used for the abrasive cleaning of a surface.

[0006] A wiping lip is used to remove a medium, especially a cleaning agent and / or a disinfectant, from a smooth surface as the wiping lip slides along it.

[0007] Wiper arrangements are also known from the state of the art in self-cleaning toilets.

[0008] US Patent 4,790,036 A discloses a self-cleaning toilet with a rotating toilet seat. A drive unit can rotate the toilet seat and, in combination with a cleaning unit, perform the cleaning. The cleaning unit can have various components, including a wiper assembly with a wiping lip. The cleaning unit is mounted on a movable arm and, during operation, can be placed onto the rotating toilet seat by means of the movable arm. The toilet seat is cleaned by rotating it 360° (i.e., by one complete rotation of the toilet seat) or by rotating it 360° multiple times (i.e., by multiple rotations of the toilet seat) and by contact with the cleaning unit.

[0009] WO 02 / 051295 A1 discloses a self-cleaning toilet, wherein the cleaning unit is mobile and can be moved in two directions over the entire circumference of a static toilet seat. In contrast to the previous toilet, the relative movement between the cleaning unit and the toilet seat is therefore not due to the toilet seat but to the moving cleaning unit.

[0010] Further self-cleaning and / or self-disinfecting toilets are described in CN 107713889 A and US 4734942 A. A disadvantage of prior art wiper arrangements is that these wiper arrangements can only be used for one function, specifically for removing a medium from a surface.

[0011] A particular disadvantage of wiper systems is their limited functionality when disinfecting surfaces. For example, in self-cleaning toilets, a disinfectant is often applied to the toilet seat by a cleaning unit to kill germs for hygienic reasons. However, the disinfectant cannot remain in contact long enough to kill a sufficient number of germs because the wiper mechanism of the cleaning unit removes the disinfectant from the surface shortly after application.

[0012] The object of the present invention is therefore to overcome at least some of the disadvantages of the prior art and to provide an improved wiper arrangement compared to the prior art, which is characterized in particular by improved functionality. The object is further to provide a toilet with such an improved wiper arrangement and a method for cleaning and / or disinfecting the toilet seat of such a toilet.

[0013] This problem is solved by the features of claims 1, 8 and 11.

[0014] This problem is solved by means of a wiper arrangement according to claim 1, namely by a wiper arrangement for a self-cleaning and / or self-disinfecting toilet with at least one wiper lip, wherein the at least one wiper lip has at least one wiping edge and has at least one surface area along the at least one wiping edge at least on one side, wherein the at least one surface area is uneven along a longitudinal extent of the at least one wiping edge because the at least one uneven surface area has a plurality of protrusions and / or depressions.

[0015] The uneven surface area of ​​the wiper blade allows for a wider distribution and longer contact time of cleaning agents and / or disinfectants. This is described below using the example of a self-cleaning toilet.

[0016] When a wiper assembly glides along a surface to be cleaned and / or disinfected—in this example, a toilet seat—the wiper blade does not make continuous contact along one edge. The contact between the wiper blade and the toilet seat is interrupted by the numerous protrusions and / or indentations along at least one edge. Therefore, the wiper blade only makes contact with the toilet seat in sections or at specific points, depending on the design of the protrusions and / or indentations. For example, the wiper blade may only make contact with individual protrusions, leaving gaps between the wiper blade and the toilet seat.

[0017] The technical effect of the wiper arrangement in this example is that, as the wiper glides along the toilet seat, a previously applied cleaning agent and / or disinfectant is only partially pushed along by the wiper blade. Some of the cleaning agent and / or disinfectant passes between the protrusions and / or recesses, through the gaps between them, and thus along the gliding wiper blade. In this way, the cleaning agent and / or disinfectant can be distributed evenly across the toilet seat. This results in a more extensive coating of the toilet seat and allows for a longer contact time.

[0018] The advantage here is that, depending on the design of the protrusions and / or recesses, the distribution of the cleaning agent and / or disinfectant can be precisely controlled. Different sizes and / or spacing of the protrusions and / or recesses, and / or the number of protrusions and / or recesses, allow for the distribution of varying amounts of cleaning agent and / or disinfectant.

[0019] In the aforementioned example, it is now preferable to change the direction of sliding of the wiper assembly, i.e., to change the direction of the relative movement between the wiper assembly and the toilet seat. This ensures that the uneven surface area of ​​the wiper blade no longer makes contact, but instead a different, preferably flat, surface area of ​​the wiper blade slides over the toilet seat and removes the cleaning agent and / or disinfectant in the usual manner, as is known from the prior art for wiper blades.

[0020] Another advantage is that a freely selectable pause time is allowed between changes in the direction of the wiper assembly's sliding motion, specifically changes in the relative movement of the wiper assembly, thus taking into account the contact time of the cleaning agent and / or disinfectant by the cleaning unit.

[0021] It should be noted here that brushes and sponges are fundamentally different from wiping blades, both in terms of their construction and their use. A professional would therefore understand that a wiping blade is neither a brush nor a sponge.

[0022] For the sake of completeness, it should be noted that in the description of this invention, the numerical terms used, such as one, two, three, and the like, generally only describe the minimum quantity of a feature of the wiper arrangement according to the invention. Individual features or components can, of course, be present in larger numbers. For example, wiper arrangements according to the invention can have more than one wiping lip, and each wiping lip can have more than one uneven surface area, more than one wiping edge, etc.

[0023] Further advantageous embodiments of the arrangement are defined in the dependent claims.

[0024] Furthermore, protection is sought for a self-cleaning and / or self-disinfecting toilet with a toilet seat and a cleaning unit, wherein the cleaning unit has at least one wiper arrangement according to the invention.

[0025] Furthermore, protection is sought for a method for cleaning and / or disinfecting a toilet seat, wherein a self-cleaning and / or self-disinfecting toilet, preferably a toilet according to the invention, is provided with a toilet seat and a cleaning unit, wherein the cleaning unit has at least one wiper arrangement according to the invention, wherein the following method steps are provided: Applying a cleaning agent and / or a disinfectant to the toilet seat, preferably by means of an application device or at least one wiper arrangement, and wiping the toilet seat by means of the at least one wiper arrangement. where, optionally, between application and removal, the cleaning agent and / or disinfectant is distributed on the toilet seat by means of at least one uneven surface area of ​​the at least one wiper arrangement.

[0090] A toilet seat 18, for example, can be rotated by means of the drive 20, as revealed in US 4 790 036 A. In addition to the drive 20, Fig. 24 Further devices, such as a toothed guide on the underside of the toilet seat 18, may be provided for this purpose, which are located in the Figs. 23 and 24 are not shown.

[0091] A movable arm 21 can, for example, be mounted on the toilet seat 18, as disclosed in US 4,790,036 A. It can also be provided that the movable arm 21 can be extended from a housing during operation and retracted into a parking position within the housing when not in use.

[0092] In a preferred embodiment of the toilet 2, the cleaning unit 19 can be provided to be a mobile cleaning unit 19 and to be movable along the toilet seat 18 and / or over the toilet seat 18, preferably by means of a drive 20.

[0093] A mobile cleaning unit can, for example, be designed as disclosed in WO 02 / 051295 A1.

[0094] In a preferred embodiment of toilet 2, it can be provided that either the cleaning unit 19 is static and the toilet seat 18 is rotatable, or the cleaning unit 19 is mobile and the toilet seat 18 is static, or the cleaning unit 19 and the toilet seat 18 are mobile.

[0095] Regardless of whether the toilet seat 18 and / or the cleaning unit 19 can move, in a preferred embodiment of the toilet 2 a relative movement takes place between the cleaning unit 19 and the toilet seat 18.

[0096] In a particularly preferred embodiment, the relative movement can be carried out in a first direction of movement 28 or a second direction of movement 29. Based on the top view in Fig. 24 For example, the first direction of movement 28 of the relative movement is counterclockwise and the second direction of movement 29 of the relative movement is clockwise.

[0097] As from the Figures 23 and 24As can be seen, as a result of the relative movement of the cleaning unit 19 and the toilet seat 18, an upper side of the toilet seat can be cleaned with the wiper arrangement 1 of the attached cleaning unit 19, since the entire circumference of the upper side of the toilet seat 18 is moved past the wiper arrangement 1 in the course of a rotation by 360° or in other words in the course of a complete cycle of the relative movement.

[0098] In a preferred embodiment of the toilet 2, it can be provided that a control unit 22 and an actuating element 23 connected to the control unit 22 are provided, wherein the control unit 22 is configured to perform a method for cleaning and / or disinfecting the toilet seat 18 when the actuating element 23 is actuated.

[0099] Fig. 25shows a schematic procedure for cleaning and / or disinfecting a toilet seat 18 with or without the optional procedure step of distributing 26 the cleaning agent and / or disinfectant.

[0100] Fig. 25 Figure 1 shows a method for cleaning and / or disinfecting a toilet seat 18, wherein a self-cleaning and / or self-disinfecting toilet 2, preferably a toilet according to the invention, is provided with a toilet seat 18 and a cleaning unit 19, wherein the cleaning unit 19 has at least one wiper arrangement 1 according to the invention, wherein the following method steps are provided: Applying 24 a cleaning agent and / or a disinfectant to the toilet seat 18, preferably by means of an application device 10 of the at least one wiper arrangement 1, and wiping 25 the toilet seat 18 by means of the at least one wiper arrangement 1, where optionally, between the application 24 and the removal 25, a distribution 26 of the cleaning agent and / or disinfectant on the toilet seat 18 is provided by means of at least one uneven surface area 5 of the at least one wiper arrangement 1.

[0101] If a method for cleaning and / or disinfecting a toilet seat 18 with a wiper arrangement 1 according to the invention is carried out without the optional spreading step 26, this can also be described as a method without the possibility of a longer contact time. This means that the wiping step 25 can be carried out during or immediately after the application step 24. Such a method could also be described as a normal operating method. A normal operating method offers the advantage that the cleaning and / or disinfection can be carried out quickly, in particular faster than with an intensive operating method.

[0102] If a method for cleaning and / or disinfecting a toilet seat 18 with a wiper arrangement 1 according to the invention is carried out with the optional process step 26, this can also be described as a method with the possibility of a longer contact time. This means that the process step 25 can only take place after a certain contact time of the cleaning agent and / or disinfectant following the process step 24 and the process step 26. Such a method could also be described as an intensive operating method. An intensive operating method offers the advantage that the cleaning and / or disinfection can be carried out particularly thoroughly, especially more thoroughly than in a normal operating method.

[0103] Fig. 26shows a schematic procedure for cleaning and / or disinfecting a toilet seat with procedure step 26 distributing the cleaning agent and / or disinfectant and an optional pause 30.

[0104] In a preferred embodiment of the method, it can be provided that the process step applying 24 and the process step removing 25 are carried out simultaneously, immediately one after the other, or sequentially at different times.

[0105] In a preferred embodiment of the method, it can be provided that the process step peeling 25 is carried out by means of a flat surface area 9 of the at least one wiper arrangement 1.

[0106] As already mentioned in the examples in the Figs. 1 to 22As shown and described in more detail above, the wiper arrangement 1, specifically the at least one wiper lip 3, can have at least one uneven surface area 5. The at least one uneven surface area 5 is uneven due to a plurality of projections 7 and / or depressions 32 along at least one wiping edge 4 of the at least one wiper lip 3, at least on one side along a longitudinal extension 6 of the at least one wiping edge 4.

[0107] In addition to such an uneven surface area 5, the at least one wiper lip 3 can additionally have at least one other surface area 8. The at least one other surface area 8 can be at least one flat surface area 9. Preferably, the other surface area 8 can be flat along at least one wiping edge 4 of the at least one wiper lip 3, at least on one side along a longitudinal extension 6 of the at least one wiping edge 4.

[0108] The at least one flat surface area 9 can, conversely to the uneven surface area 5, be free of a plurality of projections 7 and / or depressions 32, preferably free of any projections 7 and / or depressions 32. In other words, the flat surface area 9 can be smooth.

[0109] The Figures 27 to 30 show schematic representations of a relative movement 27 between a wiper arrangement 1 and a toilet seat 2 with a first direction of movement 28 and a second direction of movement 29.

[0110] The following show Figures 27 to 30 a front view of a section of toilet 2 from Fig. 23 . The chosen perspective corresponds to the view from the center of the toilet seat 18 towards the cleaning unit 19, whereby, apart from a part of the toilet seat 18 and a part of a wiping lip 3, all other components are hidden.

[0111] Fig. 27Figure 1 shows a wiping lip 3 which is attached to the top of the toilet seat 18. In this example, the relative movement 27 originates solely from the wiping lip 3, as indicated by the arrow pointing in the first direction 28 of the relative movement 27. Fig. 27 emerges.

[0112] As a result of the relative motion 27 of the wiper lip 3, the wiper lip moves in Fig. 27 to the right, i.e., in the first direction of movement 28 of the relative movement 27, and slides with the uneven surface area 5 over the top of the toilet seat 18. In the course of this, the wiper lip 3 can become deformed, so that only the majority of the projections 7 contact the toilet seat 18 as they slide along. An example of such a deformed and contacting wiper lip 3 is shown with dashed lines in Fig. 27As shown. In this way, a cleaning agent and / or disinfectant can pass between the projections 7 and the wiping lip 3, specifically the wiping edge 4, be distributed homogeneously over the top of the toilet seat 18 and remain on the top of the toilet seat 18 despite the wiping lip 3 sliding along it.

[0113] Fig. 28 shows the arrangement Fig. 27 , wherein the relative motion 27 originates from the moving wiper lip 3 and proceeds in the second direction of motion 29. A deformation of the wiper lip 3 can also occur, whereas in contrast to Fig. 27 A flat surface area 9 contacts the top of the toilet seat 18. The projections 7 of the uneven surface area 5 on the opposite side of the wiper blade do not contact the toilet seat. An example of such a deformed and non-contacting wiper blade 3 is shown with dashed lines in Fig. 28As shown. In this way, the flat surface area can, as known from the prior art, remove a cleaning agent and / or disinfectant from the top of the toilet seat 18.

[0114] The Figures 27 and 28 They thus show by way of example how a relative movement 27 in a first direction of movement 28 enables the distribution of a cleaning agent and / or a disinfectant and how, by changing the direction of movement of the relative movement 27 in a second direction of movement 29, the removal of the cleaning agent and / or a disinfectant is made possible.

[0115] The Figs. 29 and 30 differ from the Figs. 27 and 28 merely by virtue of the fact that the relative motion 27 in this example originates solely from the toilet seat 18, which is indicated by the arrow in the first direction 28 of the relative motion 27 from the Fig. 27 emerges.

[0116] As a result of the relative motion 27 of the toilet seat 18, the toilet seat 18 moves in Fig. 29 to the left, i.e. in the first direction of movement 28 of the relative movement 27. In this way the wiper lip 3 can be deformed in the same way as already in Fig. 27 shown and described.

[0117] As a result of the relative motion 27 of the toilet seat 18, the toilet seat 18 moves in Fig. 30 to the right, i.e., in the second direction of movement 29 of the relative movement 27. In this way, the wiper lip 3 can be deformed in the same way as already in Fig. 28 shown and described.

[0118] What has been said so far regarding the Figs. 27 and 28 applies analogously to the Figures 29 and 30 .

[0119] In a preferred embodiment of the method, it can be provided that the process step 24 and / or the process step 25 and / or the optional process step 26 is carried out during at least one relative movement 27 of the cleaning unit 19 relative to the toilet seat 18, wherein the at least one relative movement 27 of the cleaning unit 19 placed on the toilet seat 18 is generated by the rotation of the toilet seat 18 and / or by the movement of the cleaning unit 19 along the toilet seat 18 and / or over the toilet seat 18.

[0120] The Figures 31 to 39 show various further embodiments of a wiper arrangement 1 with at least one wiper lip 3 and at least one application device 10.

[0121] In all embodiments in the Figures 31 to 39The relative movement 27 originates from the wiper arrangement 1 with the existing wiper lips 3, as already described in the Figures 27 and 28 These embodiments can be described analogously with the relative movement 27 originating from the toilet seat 18, as already described in the Figs. 29 and 30 described, combined. The relative movement 27 can therefore originate either from the wiper arrangement 1 or from the toilet seat 18, or from both the wiper arrangement 1 and the toilet seat 18.

[0122] The Figures 31 to 36 further embodiments with only one application device 10.

[0123] Fig. 31 Figure 1 schematically shows a wiper arrangement 1 with a wiper lip 3 and an application device 10, wherein the application device 10 applies, for example, a liquid cleaning agent and / or disinfectant to the top of the toilet seat 18, as shown in Figure 1. Fig. 31 depicted, can be applied.

[0124] In Fig. 31The at least one uneven surface area 5 is arranged on the side of the at least one wiping lip 3 facing the at least one application device 10.

[0125] In a preferred embodiment of the wiper arrangement 1, it can be provided that the wiper arrangement 1 has at least one application device 10, preferably an application nozzle, for applying cleaning agent and / or disinfectant to the toilet 2, wherein preferably the at least one uneven surface area 5 is arranged on the side of the at least one wiper lip 3 facing away from and / or towards the at least one application device 10.

[0126] Fig. 32 Figure 1 schematically shows a wiper arrangement 1 with two wiper lips 3 and an application device 10, wherein, in the direction of view 15 from the first wiper lip 3,11 to the second wiper lip 3,12, the first wiper lip 3,11 is logically arranged in front of the second wiper lip 3,12.

[0127] In Fig. 32 The application device 10 is arranged between the first wiper lip 3,11 and the second wiper lip 3,12 and the only uneven surface area 5 is arranged on the side of the second wiper lip 3,12 facing the application device 10.

[0128] Fig. 33 shows how Fig. 32 , schematically a wiper arrangement 1 with two wiper lips 3 and an application device 10, wherein in Fig. 33 The first wiping lip 3, 11 also has an uneven surface area 5. The uneven surface area 5 of the first wiping lip 3, 11 is located on the side facing away from the application device 10.

[0129] Fig. 34 shows how Fig. 32 , schematically a wiper arrangement 1 with two wiper lips 3 and an application device 10, wherein in Fig. 34The second wiper lip 3, 12 has a further uneven surface area 5. The further uneven surface area 5 of the second wiper lip 3, 12 is arranged on the side facing away from the application device 10.

[0130] Fig. 35 shows how Fig. 33 , schematically a wiper arrangement 1 with two wiper lips 3 and an application device 10, wherein in Fig. 35 The application device 10 is arranged in the direction of view 15 in front of the first wiper lip 3,11.

[0131] Fig. 36 shows how Fig. 33 and 35 , schematically a wiper arrangement 1 with two wiper lips 3 and an application device 10, wherein in Fig. 36 the application device 10 is arranged in the direction of view 15 after the second wiper lip 3,12.

[0132] In a preferred embodiment of the wiper arrangement 1, it can be provided that the wiper arrangement 1 has at least one application device 10, preferably an application nozzle, for applying cleaning agents and / or disinfectants to the toilet 2, wherein the at least one application device 10 in the direction of view 15 from the first wiper lip 3,11 to the second wiper lip 3,12 in front of the first wiper lip 3,11 or between the first wiper lip 3,11 and the second wiper lip 3,12 or in the direction of view 15 from the first wiper lip 3,11 to the second wiper lip 3,12 after the second wiper lip 3,12 is arranged wherein preferably the first wiping lip 3,11 and / or the second wiping lip 3,12 has at least one uneven surface area 5 on the side facing away from and / or towards the application device 10.

[0133] In the exemplary embodiments from the Figs. 31 to 36A cleaning agent or disinfectant can be applied to the toilet 2, specifically to the toilet seat 18, using the application device 10. The application process step 24 can take place during and / or before a relative movement 27.

[0134] If, after and / or during the application process step 24, a relative movement 27 in a first direction of movement 28 occurs with one of the embodiments in the Figs. 31 to 36 The cleaning agent and / or disinfectant applied to the toilet seat 18 is distributed by means of the multiple projections 7 and / or indentations 32 of the uneven surface area 5 of the second wiping lip 3,12. This occurs in accordance with the description of the Figs. 25 and 26 an intensive operating procedure, or in other words, a procedure with the possibility of a longer contact time of the cleaning agent and / or disinfectant.

[0135] It should be noted at this point that in the exemplary embodiment in Fig. 36 Due to the positioning of the application device 10 in the direction of view 15 behind the second wiper lip 3,12, the application process step 24 can be carried out in a first pass and the distribution process step 26 in a second pass of the relative movement 27. These two process steps are therefore not carried out simultaneously in this example, but sequentially.

[0136] The process step Distributing 26 can be found in the exemplary embodiments in the Fig. 31, 33 , 35 or 36 in the first direction of movement 28 of the relative movement 27 can be continued indefinitely. If, in the exemplary embodiments in the Fig. 31, 33 , 35 or 36When the direction of movement of the relative movement 27 is changed after the process steps application 24 and distribution 26 and the wiper arrangement 1 moves in the second direction of movement 29, the process step wiping 25 takes place and the previously distributed cleaning agent and / or disinfectant is wiped off, in other words removed.

[0137] The process step Distributing 26 can be described in the exemplary embodiments in Fig. 32 or in Fig. 34 The first direction of movement 28 of the relative movement 27 is continued only for 360°, or in other words, only for one complete cycle. Afterwards, the first wiper lip 3,11 reaches the starting point of the process step 1 (application 24 and distribution 26) and begins the process step 1 (removal 25) using the flat surface area 9 on the right side of the first wiper lip 3,11.

[0138] Alternatively, in the exemplary implementations in the Figs. 32 and 34Even after a first pass in the first direction of movement 28 of the relative movement 27, the direction of movement can be changed. If, after the first pass, during which the process steps application 24 and distribution 26 take place, the direction of movement of the relative movement 27 is changed to the second direction of movement 29, the process step removal 25 can then be carried out using the flat surface area 9 on the left side of the first wiper lip 3, 11 and, in the exemplary embodiment, in Fig. 32 additionally, the flat surface area 9 on the left side of the second wiper lip 3,12 is used.

[0139] If the optional process step Distribute 26 is omitted, the exemplary embodiments of the Figs. 32, 33, 34 and 36can also be used. In this mode, the application process step 24 takes place before or during the relative movement 27 in the second direction of movement 29. If the relative movement is directed in the second direction of movement 29 from the beginning, the removal process step 25 with the flat surface areas 9 on the left side of the first wiper lip 3,11 takes place directly afterwards without an intermediate distribution. Figs. 32 to 33 . It therefore takes place according to the description of the Figs. 25 and 26 a normal operating procedure, or in other words, a procedure without the possibility of a longer exposure time of the cleaning agent and / or disinfectant.

[0140] It should be noted at this point that the exemplary embodiments in the Fig. 31 and 35Due to the positioning of the application device 10 in the direction of view 15 in front of the first wiper lip 3,11, the application process step 24 can be carried out in a first pass and the removal process step 25 in a second pass of the relative movement 27. These two process steps are therefore not carried out simultaneously in this example, but sequentially, meaning no time savings can be achieved.

[0141] In a preferred embodiment of the method, it may be provided that The process step 24, the process step 25, and the optional process step 26 are carried out during a relative movement 27 of the cleaning unit 19 in the same direction of movement, or the process step 24 and the optional process step 26 are carried out during a relative movement 27 of the cleaning unit 19 in a first direction of movement 28, and the process step 25 is carried out during a relative movement 27 of the cleaning unit 19 in a second direction of movement 28, wherein preferably the second direction of movement 28 is opposite to the first direction of movement.

[0143] In a preferred embodiment of the method, the following method steps may be provided, preferably in the following chronological order: Placing the cleaning unit 19 on the toilet seat 18, initiating a relative movement 27 of the cleaning unit 19 relative to the toilet seat 18 in a first direction of movement 28, applying 24 of the cleaning agent and / or disinfectant to the toilet seat 18 during the relative movement 27 in the first direction of movement 28, preferably by means of at least one application device 10 of the at least one wiper arrangement 1, preferably until the cleaning agent and / or the disinfectant has been applied to the entire circumference of the toilet seat 18, distribution 26 of the cleaning agent and / or the disinfectant on the toilet seat 18 during the relative movement 27 in the first direction of movement 28 by means of at least one uneven surface area 5 of the at least one wiper arrangement 1,preferably until the cleaning agent and / or the disinfectant has been distributed over the entire circumference of the toilet seat 18, termination of the relative movement 27 in the first direction of movement 28, optionally a pause 30 before reversing the direction of movement of the relative movement 27, start of the relative movement 27 of the cleaning unit 19 relative to the toilet seat 18 in a second direction of movement 28, wiping 25 of the toilet seat 18 during the relative movement 27 in the second direction of movement 28, preferably by means of at least one flat surface area 9 of the at least one wiper arrangement 1.

[0144] In a preferred embodiment of the method, the following method steps may be provided, preferably in the following chronological order: Placing the cleaning unit 19 on the toilet seat 18, starting a first cycle of the relative movement 27 of the cleaning unit 19 relative to the toilet seat 18 from a starting position, applying 24 the cleaning agent and / or disinfectant to the toilet seat 18 during the first cycle of the relative movement 27, preferably by means of at least one application device 10 of the at least one wiper arrangement 1, preferably until the cleaning agent and / or disinfectant has been applied to the entire circumference of the toilet seat 18, distributing 26 the cleaning agent and / or disinfectant on the toilet seat 18 during the first cycle of the relative movement 27 by means of at least one uneven surface area 5 of the at least one wiper arrangement 1, preferably until the cleaning agent and / or disinfectant has been distributed to the entire circumference of the toilet seat 18.Continuation of the first cycle of the relative movement 27 of the cleaning unit 19 relative to the toilet seat 18, until the cleaning unit 19 reaches the starting position of the relative movement 27 again, optionally a time pause 30 before a second cycle of the relative movement 27, start of the second cycle of the relative movement 27 of the cleaning unit 19 relative to the toilet seat 18 starting from the starting position, removal 25 of the toilet seat 18 during the second cycle of the relative movement 27, preferably by means of at least one flat surface area 9 of the at least one wiper arrangement 1.

[0145] The optional process step "time pause 30" can be performed for a specific duration. The duration of this step can be adjusted to the contact time of a cleaning agent and / or disinfectant. Alternatively, or in addition, the duration can be adjusted to other process parameters, such as the degree of soiling, the frequency of cleaning and / or disinfection, and similar factors.

[0146] In the preferred methods described above, the individual process steps can also be carried out in a different order than listed.
