Abstract

A device for wringing moisture from a mop includes pressure elements between which a holder of the mop, together with a mop cover attached thereto, can be pressed. The mop cover projects beyond the holder, thereby forming a cushion at edges of the holder in order to prevent the holder from doing damage, for example to furniture. In order to be able to wring moisture in a defined manner from both the projecting edge of the mop cover as well as the portion thereof covered by the holder, the two interacting pressure elements form a gap having a height which decreases toward the edges. In particular, the height decreases in a gradual manner. The pressure elements are preferably rollers, several cylinder sections of which can have different diameters in order to be able to obtain gap sections of different heights.

Description

The present invention relates to a wet mop with a holder for attaching a mop cover, in particular for use with a device for squeezing the mop cover.

By the DE 100 653 69 A1 a device for moistening and dehumidifying a wet mop with an absorbent mop cover is known, wherein the device comprises a nozzle for wetting the mop cover and two rollers, one of which is drivable in the direction of rotation. The rollers are arranged such that between them, the mop cover can be passed and thereby pressed or dehumidified. The mop cover is attached to the bottom of a rigid flat holder of the wet mop, the mop cover and the holder have the same outline. Disadvantageously, this has the consequence that the wet mop strikes when bumping against obstacles with the stiff holder and thereby damage the obstacle under certain circumstances.

In addition, be on the US 2002/026680 A1 which relates to a cleaning device with device for attaching a cloth.

The present invention has for its object to provide a wet mop of the type mentioned, which can be dehumidified in a device for pressing the mop cover and in which the risk of damage to objects is reduced.

This is achieved by a device having the features of claim 1 according to the invention. The subclaims each define preferred and advantageous embodiments of the present invention.

According to the invention, the holder, to which the mop cover is fastened, has a rigid core and an edge trim. Due to the stiff core, it is possible to exert pressure on the entire surface of the mop cover and to dehumidify the mop cover evenly over its surface. In this case, due to the stiff core, the pressure on the holder does not necessarily have to be applied evenly over the surface, but the pressure can also be applied only at the edges of the holder. This advantageously makes it possible to design the squeezing device for the mop cover more variably. Furthermore, this also allows a holder with attached handle to Use, because at the necessary connection point between stem and holder can be applied very difficult pressure on the holder.

Likewise, the object of the invention is achieved by a flat holder, to which a soft flat mop cover is attached, which projects beyond the holder on at least part of the circumference of the holder. Since the mop cover is soft, it can provide protection against damage to other objects by the holder, which is usually hard to achieve sufficient stability for use in a mop wringer squeezing device. Preferably, the mop cover is at the points on the holder on where strikes with an increased probability of the holder against an obstacle.

A mop cover overhanging the holder may also be used in conjunction with a holder having a hard core with a compliant edge trim.

The edge trim in turn ensures that when hit with the holder to an obstacle, in particular a piece of furniture, the obstacle is not damaged by the core. By combining the rigid core with an edge trim as edge protection for the holder on the one hand the necessary stability for use in a squeezing device can be created and on the other hand, the risk of damage to obstacles are reduced.

The core may for example be made of metal or a stable, in particular fiber-reinforced plastic. Furthermore, the core is preferably itself flat, so that it can advantageously be used together with a flat mop cover.

The resilient edge trim is preferably elastic and may be in particular of a plastic material such as an elastomer. Furthermore, the edge trim may be provided along the entire circumference of the core rim. Likewise, the edge trim can be provided only in some places of the core edge, in particular sites are selected for the arrangement of an edge trim, which are exposed and abut when using the wet mop with increased probability of obstacles.

The edge trim can be connected, for example by frictional engagement with the core, for example, by the edge trim is clamped around the core on the edge. Furthermore, in the edge, a groove or a depression may be provided, in which an extension of the edge trim is pressed. Alternatively or additionally, the edge trim can also be attached by positive locking to the core. For example, the edge trim may be configured to surround the core by revolving around the entire periphery of the core edge and projecting slightly above and below the core. Furthermore, the edge trim can also encompass corresponding sections of the core edge, the thickness of which increases toward the outside.

In a particularly advantageous embodiment, the core is encapsulated with the edge trim, so that there is a particularly close connection between the core and edge trim, leaving no or only a very small gap, so that no contamination between the core and edge trim can collect. Further, by molding, the edge trim can be attached to the core at a low cost.

The edge trim may also completely enclose the core or be part of a shell for the core. This has the advantage that the core is no longer exposed to the environment and thus also no corrosion. In this case, a low cost material may be used to make the core that, while having the required mechanical properties, may easily corrode. This applies to many metals. Since the wet mop necessarily comes into contact with liquid and in particular with water, by the complete enclosure of the core, a cost-effective construction can be achieved by using for the core as a material a cheap, but corrosion-prone metal completely to prevent corrosion more resistant material such as plastic, which additionally fulfills the function of edge protection.

If the core is made of a plastic, a plastic edge trim can also be molded so that the two plastics melt together at the joint in part. This can be a part with a sliding transition between the Plastic materials and thus the material properties are created in the holder, with a very intimate connection between the core and edge trim is achieved.

The wet mop according to the invention is particularly adapted for use in a device for dehumidifying or squeezing the mop cover, wherein the device can compress the holder and thus the mop cover between printing elements and on the opposite side of the mop head pressure elements not the pressure over the entire surface of the holder but do not generate pressure at least in a region of the holder surface. This results in the frequent cases in which the holder is connected to a stem, which is not removed before dehumidifying.

In particular, for use with a squeezing device, the holder is preferably arranged so that its thickness remains constant over the surface. For this purpose, the core and its edge trim must be coordinated so that in the area in which the core and the edge trim overlap, the common height remains constant. This facilitates that in the device for dehumidifying the distance between interacting pressure elements across the width or area can remain constant and the pressure elements can be formed with a simpler shape. To achieve a consistent thickness, the core may be made thinner in the area where the edge trim extends above or below it.

Fig. 1 shows a schematic diagram for a flywheel drive. In Fig. 1 1 denotes a wiper device for wet wiping and thus cleaning of floors in the home or in other interior spaces. she is in Fig. 1 shown as a simple cuboid. The wiper device 1 rests on a floor 2 and faces it with a wiping surface 3.

In the wiper device 1, a flywheel 4 shown here only symbolically is provided, which is mounted horizontally movable in a manner not shown. In the present case, it is driven via a likewise only symbolic lever linkage 5 by a drive motor 6, against the force of a spring 7. Thus, the drive motor 6 biases the spring 7 to a certain point, whereupon a trigger mechanism, the flywheel 4 of the force the drive motor decoupled or the drive motor 6 unlocks. Then, the spring 7, the flywheel 4 relatively quickly - accelerate, in Fig. 1 directed to the left. During this acceleration phase, this results in a reaction force on the base, ie the remaining wiper device 1, the wiper device 1 against the static friction between the wiping surface 3 and the floor 2 in the sense of Fig. 1 accelerates to the right.

Due to the sliding friction between the wiping surface 3 and the floor 2, this movement is decelerated again after a certain sliding distance. Furthermore, the spring 7 has pressed the flywheel 4 away from itself, so that the drive motor 6 can move the flywheel 4 again via the lever linkage 5 to the right to tension the spring 7. However, it comes to such small accelerations of the flywheel 4 to the right that the tensioning of the spring 7 does not lead to a complementary jerky movement of the wiper device 1 to the left. By iterative repetition of the described process, the wiper device 1 slips thus overcoming the static friction between the wiping surface 3 and the floor 2 piecewise to the right. Thus, on a model example, the basic principle of the flywheel mass drive, in particular with regard to a linear movement of the flywheel 4, explained.

Alternatively, the movement of the flywheel 4 could be used by the drive motor 6 as a flywheel movement for the movement phase; the wiper device 1 then moves stepwise to the left. The spring 7 is used here only as energy storage to return the flywheel 4 back to the starting position for a new acceleration by the drive motor 6. The spring 7 is representative of energy storage of any kind, which may be, for example, electrically (capacitors). It should be clarified that the energy for the return of the movement does not necessarily have to come from the drive motor 6.

Fig. 2 shows a very similar model case, in which the same reference numerals as in Fig. 1 be used. The difference of in Fig. 2 illustrated mechanism to the off Fig. 1 consists in the tilting of the trajectory of the flywheel 4 against the horizontal by the angle α. This has the consequence that in the acceleration of the flywheel 4 by the spring 7 on the wiper device 1, a reaction force or repulsive force acts, which is also tilted by the angle α relative to the horizontal. So it has a gravitational force opposing component. On the focus of the wiper device 1 so not only acts a directed to the right horizontal force impact but also a vertically upwardly directed impulse. To put it bluntly, the wiper device 1 becomes lighter in this movement phase, ie the resulting force acting on the friction between the wiping surface 3 and the floor 2 becomes smaller. This is to clarify that the interpretation of the flywheel drive can be influenced not only by temporarily larger and smaller delays and accelerations but also by their direction on when the static friction is overcome and when not.

Another alternative to using the FIGS. 1 and 2 functions shown is to make the flywheel 4 and the spring 7 as a linear oscillator by the drive motor 6 to perform a natural vibration, preferably in one near-resonance state. At the inclined by the angle α variant Fig. 2 arise as a result of the different influence of the static friction in the two reversal points of this vibration already the desired adhesion phases and Gleitbewegungsphasen. In the variant off Fig. 1 For example, the flywheel 4 could be braked relatively hard at one of the two reversal points, for example by means of an elastic wall (not shown) or another comparatively harder spring. There would then arise correspondingly large deceleration forces with which the static friction can be overcome.

Fig. 3 illustrates another embodiment of a flywheel mass drive. Here, two flywheel masses 4a and 4b are provided, which are mounted eccentrically and rotatably. With 8a and 8b, the axes of rotation of this rotational movement are designated. The two flywheels 4a and 4b rotate synchronously and in opposite directions. It can be seen that the planes of rotation and the axes of rotation 8a and 8b are inclined. The synchronous rotational movements of the flywheel masses 4a and 4b are simultaneously in the uppermost (in Fig. 3 shown) and the lowest vertex. At the top apex, the centrifugal forces add up with a gravitationally decreasing vertical component and a horizontal component. The horizontal components are each denoted by F ₁ and the vertical components in each case by F ₂ . The obliquely directed centrifugal force, however, with F _z . The centrifugal forces can thus move the wiper here designated 9 by a certain sliding distance to the right. Although the centrifugal forces also add up in the respective lowest vertex of the rotational paths of the flywheel masses 4a and 4b, they reinforce the force of gravity of the wiper device 9 and the vertical component of the centrifugal forces that is essential in terms of static friction. Due to the opposite rotation of the two flywheel masses 4a and 4b, the inertial forces in the remaining region of the respective webs at least partially compensate each other, so that the static friction is likewise not exceeded there. Rather, the sliding phase only affects a specific temporal environment of the state Fig. 3 , With a suitable design, ie coordination between the coefficients of friction, the masses, radii and speeds as well as web tilting angles of the flywheel masses 4a and 4b, it can be achieved that the wiper device 9 remains straight in these deepest apexes as a result of the static friction. In this embodiment, the iterative sliding phases can thus be achieved by a continuous circular motion of the flywheel masses.

Fig. 4 shows the stoppage phase. Here are the momentum masses in each deepest vertex of the respective circular motion.

Fig. 5 shows a further wiper device 10 with a flywheel mass here only symbolically illustrated, the explanations to the Fig. 3 and 4 equivalent. Symbolically drawn are an electronic controller 11 with a microprocessor for program control of the wiper device, a memory, an evaluation device for position and acceleration sensors or collision sensors, which are arranged on the side edges of the wiper device 10, but not shown, as well as an electronics for monitoring with 12 designated power electronics, which controls the charging and discharging of electric batteries and the motor drives the flywheels 4a and 4b. The person skilled in the electrical details of such a control readily apparent.

The wiper device 10 off Fig. 5 further shows not only on its underside a wiping cloth 13, the underside of which forms the currently used wiping surface, but at the top of a not used in the illustrated state further wiping cloth 14. The wiper device 10 may thus either by the user by hand or by a further Course still explained base station are turned over in order to continue wiping with the second wiper fabric 14 when the other mop textile is dirty or used up. The wiper device shown here has a numerical ratio of the edges in the projection on the floor of about 3: 1. This makes it easy to clean narrow spaces and, on the other hand, to achieve effective web widths over large areas.

Fig. 6 illustrates in a plan view of a gimbal bearing the flywheels 4a and 4b of the Fig. 3 to 5 , With 9 and 10, the "solid" base of the corresponding wiper device is indicated. The viewing direction is directed from the top to the floor level. A first axis of rotation 15 holds a first gimbal 16, to which a second axis of rotation 17 is attached, which is rotated to the first axis of rotation 15 by 90 °. The second axis of rotation 17 holds a second gimbal 18, on which the flywheel 4a and 4b is rotatably mounted about the axis of rotation 8a to 8b. The motor drive of the flywheel 4a or 4b is preferably carried out in the Kardanlagern provided electric motors or else by flexible waves, which are brought by fixed to the base 9, 10 mounted motors, but not shown in the drawing. The gimbal bearing with the axes 15 and 17 can be adjusted by also not shown servo motors via lever linkage with on the rings 16, 18 on the axes of rotation 15 and 17 applying levers.

Together with the explanations to the previous ones Fig. 3 to 5 results from the fact that the wiper device 9, 10 can adjust by adjusting the rotational speeds and planes of rotation to different friction conditions between respective wiping fabrics or other wiping surfaces and different floors, even if they are directional. In particular, the electronic controller 11 can detect when the wiper device 9, 10 moves and, for example, by increasing tilting of the planes of rotation strive for a state in which the static friction is overcome in phases and phase wise but still exists. Furthermore, the wiper device 9 and 10 can move in any horizontal direction as a result of the gimbal bearing. Incidentally, it can easily be imagined that by separately controlling the planes of rotation and / or the rotational phases of the two flywheel masses 4a and 4b, a rotation of the wiper device 9, 10 about a vertical axis can be achieved, for instance by reducing the centrifugal forces of the centrifugal masses at maximum gravitational reduction Vertical component are opposite or the overlaps with the gravity on both sides are different. Of course, any superpositions of rotational movements and translational movements can be achieved.

For an angular momentum drive you would have to in Fig. 3 and the following figures instead of the eccentrically suspended centrifugal masses projecting concentric center of gravity. Their angular momentum could, for example, be substantially horizontal and act by a sudden change from the original position to an angular momentum acting on the base with a vertical direction. This vertical angular momentum could turn part of the wiper device. If, at the same time, a horizontal-angular momentum component provides end weighting, it could serve as a pivot for pivotal movement of the wiper. Subsequently, with the reverse direction of rotation and at the corresponding other end of the Wischvorrichtung made weighting a further step to be done, so that there is also an iterative Fortbewegungsmöglichkeit.

The described drives are all arranged inside and above the wiping surface.

Fig. 7 shows a further rotational movement of a flywheel 19. The flywheel 19 is mounted eccentrically in a planetary gear 20, wherein the center of gravity is denoted by 21. The planetary gear 20 runs on a fixed sun gear 22, although the center of the planetary gear describes a circular path, the center of gravity 21, however, a dashed elliptical 23. In the present case, one can imagine that the axis of rotation of the planetary gear is driven by a designated 24 belt drive is. These Fig. 7 serves only to illustrate the fact that can be achieved at different times already with the trajectory of the center of gravity of the flywheel different sized centrifugal forces. In addition, the flywheel can of course be accelerated or decelerated in its orbital motion even in the web speed itself. In addition, the already mentioned possibilities of mutual compensation of inertial forces of two or more centrifugal masses come into consideration.

As a result of an orientation of the longitudinal axis of the elliptical path in Fig. 7 would be with this drive already achieve an inertial drive without inclination of the web plane and with only one flywheel 19.

Fig. 8 shows another example of a basic possibility of a flywheel drive. With 25 symbolically a wiper device is indicated in plan view. This is a bearing 26 is provided in which an eccentric crescent-shaped flywheel 27 is guided in rotation. About a lever linkage (double crank with joint) 28 can be achieved via a motor connected to the point 29, a movement of the flywheel 27. This movement is uneven at a uniform engine speed and accordingly also leads to an inertial drive of the wiper device 25 with sliding phases and adhesion phases.

Fig. 9 shows an alternative drive, so no embodiment of a flywheel mass drive. Here is within a wiper device 30 within the (in plan view from Fig. 9 the wiping device 30 corresponding wiper surface arranged wheel drive provided in which two wheels 31 and 32 can be driven independently of each other and rotated relative to the wiper device 30. The wheels are shown in two different positions, but there are two wheels altogether. As a result, the wiper device 30 can be transported with its wiping surface over the floor, whereby any movement directions and also rotations of the wiper device 30 due to speed differences between the wheels 31 and 32 and by motor adjustment of the angle of the axes of rotation of the wheels 31 and 32 relative to the wiper device 30 to achieve their own axis. It must be ensured that the adhesion between the wheels 31 and 32 and the floor in relation to the sliding friction of the wiping surface is sufficiently high.

Fig. 9 clarifies in particular that even with this drive an arrangement within the wiping surface is possible and possibly caused by the wheels 31 and 32 traces on the floor, regardless of the direction of movement can be wiped away again. Namely, the wiping surface is a surface closed around the drive.

In particular, in connection with the wheel drive can be provided to rotate the wiping surface relative to the drive rotating or otherwise, to increase the mechanical cleaning effect. For this purpose, a flywheel can be used. Incidentally, of course, the flywheel drives in the various examples can be supplemented accordingly.

Fig. 10 shows a front view of a wiper device 33, which has a over the lateral edge of the actual wiper device 33 protruding wiping cloth 34. This wiping cloth 34 serves as edge protection and also limits the dimensions of the wiper device 33 in the projection onto the floor. This can be particularly efficiently wiped along wall edges along, without the risk of damage due to abutment of the wiper device 33 is. Of course, the wiping devices can also have corresponding impact protection edges independently of wiping textiles, which, in addition, also assume senoric tasks can to inform the aforementioned electronic controller 11 about a collision with an obstacle.

Fig. 11 shows as a schematic diagram in the direction of Fig. 10 illustrated cross-sectional view through a base station 35 for regenerating the wiper device 33. In this case, the wiper device 33 is guided with the wiper textile 34 between Auspresswalzen 36, 37, 38 therethrough. The distance between the squeezing rollers 36 and 37 and between the squeezing rollers 38 and 37 is adjustable so that the force with which the squeegee 34 is squeezed out can be suitably determined. The squeezing rollers 38 press on the wiper device 33 itself and the squeezing rollers 36 on the protruding edges of the wiper textile 34, wherein the squeezing rollers 37 form an abutment. The squeezed cleaning liquid flows down in the manner indicated.

Fig. 12 FIG. 12 shows a more specific example of the base station embodiment, designated 39 here. The wiper device 33 from Fig. 10 or for example, the wiper device 10 from Fig. 5 or the wiper device 9 from Fig. 3 can be left in with the help of their own drive Fig. 12 shown position to be driven. There they are gripped by two levers 40, which can be tilted by motor in the manner indicated. Here are explained in more detail below spring-loaded pins behind undercuts in the in Fig. 12 recognizable grooves 41 at the respective front portions of the longitudinal sides of the wiper device 33 is engaged. Thus, the lever 40, the wiper 33 can grip and raise in the manner shown tilt, whereby the front end of the wiper device 33 is guided between Auspresswalzen 42 and 43. The squeezing rollers 42 and 43 further pull the wiping device 33 obliquely upward, disengaging the insertion pins from the detents and instead continue to run in the grooves 41 as a guide. The wiper device 33 is transported in this way on an inclined plane 44, wherein the squeezing rollers 42 and 43 express residual moisture in the wiper textile 34.

The effluent cleaning liquid flows through a passage filter 45 into a dirty water tank 46, from which the cleaned by the filter 45 cleaning liquid by means of a pump 47 a nozzle 48 is supplied to the cleaning liquid to improve the cleaning before squeezing and / or Retracting the wiper device 33 sprayed onto the wiper cloth 34 again. The transport of the wiper device 33 is otherwise supported by a further transport roller 49. Furthermore, a fresh water tank 50 is provided, which contains clear fresh water for rinsing, for example, for a final wipe cleaning, and accordingly can be connected to the nozzle 48 in a manner not shown. Furthermore, the cleaning system in the manner already described a multiple, first wet and then dry wiping perform.

The oblique movement of the wiper device 33 on the plane 44 allows easy transport of the wiper device 33 by means of the motor-driven lever 40 in the base station 39. Thus, the bottom and thus the wiper textile 34 of the wiper device 33 is accessible and space for the described components under the Level 44 created. Incidentally, the hydraulic unit on the continuous filter 45, dirty water tank 46 and nozzle 48 and fresh water tank 50 can be removed completely as a module.

The distances between the rollers 42 and 49 relative to the rollers 43 are adjustable in order to ensure optimum squeezing and sufficient adhesion for transport. This is otherwise the residual moisture in the cleaning fabric 34 adjustable. The setting can be done for example by eccentrics in the rotary axis bearings.

Fig. 13 illustrates the already mentioned locking mechanism for gripping the wiper device 33 by the lever 40. Bottom left one of the two levers 40 can be seen, which carries at its end a spring 51 by a spring-mounted pin 52. It should be noted that the Fig. 13 opposite the Fig. 12 is reversed. It can be seen that the previously mentioned groove 41 in its initial region, ie in the vicinity of their in Fig. 12 right and in Fig. 13 left end has an undercut 53, in which the pin 52 can engage. The engagement is facilitated by a slope 54 at the beginning of the groove 41. The disengagement from the undercut can be done either by a similar slope with the help of the forces exerted by the squeezing rollers 42 and 43 or by means of a further mechanical disengagement, which is indicated here by the motor-driven fork 55. This can grip the pin 52 and outward from the undercut Pull out 53. In the following, the pin 52 then slides along the groove 41 as a guide.

There are, of course, other ways of transporting the wiper device 33 driven by a motor into a base station, such as portals, cranes, elevators, chain drives, cables and the like. In particular, a base station can also be designed to have a wiper device with two wiping textiles (cf. Fig. 5 ) to turn 180 °.

Fig. 14 schematically shows that the base station 39 may optionally serve in a second department for replacing the wiper textile 34. Fig. 14 shows how the wiper textile 34 is pulled off by two rollers 56 and 57 of not shown hook and loop fasteners on the lower surface of the wiper device 33 and stored in a container 58. Fig. 15 shows conversely how the or a fresh wiping cloth 34 can be removed by a pressure roller 59 from a container 60 and applied to the adhesive closure. For both processes, the explanations are given Fig. 12 comparable transport of the wiper device 33 in an oblique direction instead. It can also be an explanation to Fig. 12 appropriate lever mechanism can be used.

The control of the various motor-driven movement steps in the base station 39 can be done by light barriers or similar sensors. Once the wiper device 33 is gripped, but also the typical current curves of the electric motors involved can be used to draw conclusions about the respective phases of motion.

Further, as already mentioned, optical evaluations of the degree of soiling of the soil, the wiping cloth, the cleaning liquid in the wiping cloth or also in the container 46, the degree of soiling of the filter 45 and the like can be used.

Further, the base station 39 may be programmable to input certain residual humidities, cleaning cycles, wiping textile data, and the like. Moreover, wiping textiles can also contain transponders which are read out in the base station.

The electronic controller 11 of the wiper device, which may possibly be reprogrammed by an electronic control of the base station, the wiper device (in whatever specific design always), taking into account known or determined in earlier trips data of room dimensions and floor features control. The user can also specify the rooms to be cleaned and thus call up known data records or enter essential features of such rooms. Incidentally, the wiper device can perform an automatic position determination, for example by known odometric methods, by determining the movement distances and directions and thus determining the current positions. Of course, a position determination can also take place in another way, for example by laser measuring systems.

The wiping movements are preferably S-shaped, preferably with the same longitudinal edge. This means that large areas can be cleaned with just a few journeys and a small overlap of the recorded web widths. By the movement already described with always the same edge lying forward is avoided, moreover, that are deposited in curves or corners dirt.

An installation has a base station with a motorized transport device which is designed to transport the mobile device into the base station for regeneration and to transport it out of the base station.

In particular, a method for wiping floors is also presented. In the following description, however, no distinction is made in detail between the device aspect and the method aspect of the invention, so the entire disclosure is to be understood in terms of both categories.

The principle is to provide the base station with a motor means for in and out transporting the mobile device, although the mobile device itself is motor-driven. In contrast to conventional systems in which the mobile device moves by means of its drive to the base station and for example "parked" at or below corresponding connections for the regeneration, the base station is provided with its own motor mechanism, the transport device. In this way, the mobile device can be brought into a specific position without having regard to the structural design of the base station and the structural Design of the mobile device and its drive itself would have to be taken into account that the mobile device must be able to get into the appropriate position with the help of their own drive. For example, the transport device of the base station, the mobile device also raise, including their drive will not be able in many cases. Incidentally, the transport device in the base station, if desired or necessary, apply relatively large forces that the motor drive of the mobile device, which is indeed supplied for example by an electric battery or the like, not or only in a otherwise not necessary generous design this drive, can muster.

Preferably, the mobile device has a wiping cloth with which it wipes the floor for cleaning or other reasons. The regeneration then preferably includes cleaning the wiping cloth or replacing the mop cloth with a clean or a new mop cloth. The term "wipe" is to be understood very general and may include all sorts of fiber-based sheet products with which a floor can be wiped. It can thus be nonwovens, rags, furry or paper-like textiles and other.

The base station preferably includes an inclined plane on which the regeneration of the mobile device takes place and to which the mobile device is therefore brought by the transport means. The sloping plane may provide better accessibility of the underside of the mobile device, thereby facilitating the cleaning or replacement of a wiping cloth or otherwise regenerating.

The motorized transport of the base station includes at least one preferably two levers adapted to grip the mobile device. The gripped mobile device is then pulled or lifted by the levers into the base station.

The one or both levers are preferably provided with a mechanism which locks on correspondingly designed receptacles of the mobile device when it is gripped. In this case, the latching is preferably to be released again in the further course of the transport of the mobile device in the base station, wherein the lever even after releasing the latch can serve to guide the transport process in the base station.

For example, the locking mechanism may be a spring-mounted pin coupling. The coupling pins can engage behind a corresponding receptacle and lock on an undercut. Preferably, the coupling pins are provided on the levers and the receptacle with the undercut on the mobile device. The spring-mounted coupling pins can be solved by a further mechanical device in the base station or by an inclined plane on the device of the base station with the undercut over which inclined plane the pins can run up when exercising appropriately directed forces from the latch. Thereafter, the pins can for example run along in a groove without further undercut, so as to serve as a guide.

The base station preferably cleans the mobile device by passing it over a squeeze roller through which the cleaning liquid still contained in a squeegee or previously applied to clean the squeegee is expelled from the squeegee so that the dirt associated therewith is also removed. Analogously, this also applies to the squeezing out of treatment liquids that are not used for cleaning. The squeeze roller is pressed onto the mobile device with a preferably adjustable pressure. For example, the squeezing roller can be mounted eccentrically or the guide devices for the mobile device can be adjustable relative to the squeezing roller.

Furthermore, it is preferable to moisten the wiping textile after pressing new with a cleaning liquid or other liquid. In one particular embodiment, cleaning liquid is used which is recycled in the base station, that is, which has already been pressed out at a previous time. In this case, the base station may have a filter, in particular a continuous filter, for the cleaning liquid.

The new moistening can on the one hand serve to repeat the cleaning by a new pressing and to improve. Second, it may be desirable to slightly moisten or actually wet the wiper fabric prior to a new wipe of the floor. In particular, it is preferred that the cleaning system also has a two-or Multi-stage wiping can be done by first wiping the mobile device relatively wet and then absorbs the still on the floor liquid by wiping rather dry.

Furthermore, the base station can be provided with an additional device which allows replacement of a wiping textile by being pulled off an adhesive closure (so-called Velcro closure or the like) on the mobile device. Then it is further worked with a new or cleaned mop textile, which is applied to the adhesive closure again. This happens automatically in this embodiment by the base station.

In the system, the degree of soiling of the floor to be cleaned, the wiping textile used, the cleaning fluid in the base station and / or the filter for the cleaning fluid can be measured and monitored, which is preferably done optically or optoelectrically.

This description is also directed to the mobile apparatus for wiping flat surfaces wherein the drive is located within a web width sensed by the wiping surface upon movement of the apparatus by the drive.

In the embodiment, therefore, the drive is arranged within a track width detected by the wiping. This means, in particular, that the drive does not interfere with the width of the web detected during wiping, for example, when wiping just along a bottom edge. The invention makes it possible to come with the wiping surface in a relatively small distance to this edge or wipe without such a distance, because the drive, such as between the detected by the wiping web width and the bottom edge running wheel as a driving part, within the detected Web width is arranged.

The drive will lie to a considerable extent above the surface to be wiped. In particular, the drive is preferably arranged above the wiping surface, but in principle it can also be arranged in front of or behind the wiping surface in the direction of movement, as long as it remains in the web width.

This also offers the possibility of providing a relatively wide wiping surface in relation to the size of the device, which is also determined essentially by the drive.

Preferably, the wiper device has narrow and long outer dimensions in the sense of a projection onto the surface to be wiped, ie a significantly greater extent in one direction than in a second direction perpendicular thereto. The numerical ratio of the dimensions of the longest and the narrowest side is preferably at least 2: 1, better still at least 2.5: 1 and in the most favorable case at least 3: 1. A preferred basic form of the device in the projection onto the surface to be wiped is a narrow one long rectangle. Narrow long outer dimensions allow on the one hand a relatively large web width on the other hand not too large overall device. In particular, the device can be used very flexibly when passing through narrow passages or when wiping narrow corners.

It is furthermore preferred that the said outer dimensions of the device are caused by the wiping surface, ie the wiping surface forms the edges of the device in the plane of the surface to be wiped or at least essentially corresponds to it. It can optionally be provided that the wiping surface, so as a replaceable mop cover, on one or more sides over remaining parts of the device and thus on the one hand allows a particularly good wiping along bottom edges and the second forms a protective abutment edge. Of course, other abutment edges may be provided which are not formed by the wiping surface itself. In particular, it is also possible to provide abutment edges equipped with sensory properties in order to point out an automatic control of the wiper device to an abutment against an obstacle and thus to trigger corresponding control reactions.

During operation, the wiper device preferably moves forward so that one and the same longitudinal side points forwards during a wiping operation. It is then so wiped with the maximum possible web width and on the other pushed pushed together during cleaning dirt in front of him. This preferably also applies during and after cornering, so that the wiper device leaves no wiping marks in corners or curves. In particular, the wiper device in an example, right-angled corner of a floor first with said longitudinal side until it stops at the drive opposite edge, then drive back, turn 90 ° in the sense of the future direction of travel (so that the long side described now in the future direction of travel points forward), in this rotated position along the edge back to the corner drive, then from the corner continue in the new direction. In this case, a drive with front longitudinal side would be converted into a corner into a ride with the same front longitudinal side out of the corner out in the new direction of movement.

Furthermore, it can be provided that, during operation, the wiping surface moves in an oscillating manner relative to the rest of the device, for example oscillating or revolving with respect to a base of the device in one or also in two (horizontal or vertical) directions. Thus, the mechanical action on the ground can be increased without having to run over the same path multiple times.

A further embodiment provides to equip the wiper device not only on one side, but on two opposite sides with a wiping surface. The device can then be turned over by intervention of a user or automatically to be able to proceed with the second wiping surface.

Incidentally, it is preferable that the wiping surface is continuous, that is, forms a coherent surface in the mathematical sense. In addition, it is preferably closed in the sense of the direction of movement behind the ground-contacting parts of the drive, so that no traces of wheels, drive belts and the like arise. Such wheels or belts are thus preferably provided within the wiping surface or in the direction of the direction of movement in front of it or a part of it.

Furthermore, an improved drive for moving the device over a surface is provided which has a relatively movable to a base of the device and motor driven flywheel and is adapted to drive the device by moving the flywheel relative to the base by a Part of these movements, a stiction holding the device on the surface by inertia of the flywheel is overcome and not in another part of these movements, the movements of the flywheel are iterative relative to the base as a whole.

In the flywheel mass inertia forces are utilized, which arise by relative movements between a flywheel and a certain extent forming the solid part of the device base. These inertia forces, at certain stages, result in overcoming static friction that holds the device on the surface on which it is to move. In other phases, the inertia forces should not overcome the static friction. The following is a simplified talk of movement phases and detention phases. Depending on the reference system so inertial forces are transmitted to the base by the movements of the flywheel, which move them partly and adhere partly on the surface. In other words, the movements of the flywheel lead to a reaction of the base, because the entire system endeavors to correspond to the momentum conservation. However, momentum conservation is disturbed by the friction between the device and the surface. In the detention phases, the base remains on the surface, in the phases of movement it performs a movement on the surface. Preferably, this is a sliding or sliding movement, but with appropriate static friction in the adhesion phases in wheel bearings or between wheel surfaces and the surface, it could also be a rolling movement during the movement phases.

By the fact that the movements of the flywheel relative to the base are ultimately iterative, thus repeat themselves and thus enable a continuous movement, a drive concept is created that requires no direct positive connection or adhesion between drive parts and the surface on which the device is to move.

It can be achieved in particular that the wiper device touches the surface to be wiped exclusively with the wiping surface, because no wheels, drive belt or the like must be used.

For clarification, it should be noted that the flywheel is a component of the device and should not be consumed by the drive concept. Although an energy input for generating the movement will be necessary, however, the flywheel as such, in contrast to recoil drives such as rocket drives or nozzle drives should be preserved.

This provides a sliding or rolling locomotion without coupling between the drive and the transport surface. This may be of interest, for example, if a positive connection or adhesion to the transport surface can only be made with difficulty, for example on completely smooth surfaces, or if contact between the drive and the surface is not desired in the cleaning device.

There are several basic possibilities of the type of movement between the flywheel and the base. On the one hand, linear movements are conceivable, in which the flywheel is iteratively moved back and forth. By correspondingly powerful accelerations or decelerations inertial forces can be generated which are above a threshold determined by the static friction. For smaller accelerations and delays, the device remains within the static friction limits, so that the flywheel can be returned in favor of a new phase of movement of the device again.

In this connection, it may be of particular interest to provide an energy store, in particular a mechanical spring, in addition to the actual motor drive of the flywheel, which is charged and discharged with energy during the linear movements of the flywheel in synchronism with these movements. On the one hand, at least parts of the energy expended by the motor drive can thereby be recovered. Secondly, for example, provided to overcome the static friction acceleration phase can be facilitated by correspondingly large forces through the energy storage and serve the motor drive itself only to return. Thus, the drive could press the flywheel against the spring force and thereby tension the spring, whereupon the drive is switched off and it is allowed the spring to accelerate the flywheel relatively violently.

Furthermore, but also rotational movements between the flywheel and the base are possible. Preference is given to circular movements. In the case of rotational and in particular circular movements, two cases are conceivable which, in principle, could also be mixed. On the one hand, the actual conservation of momentum in the sense of the linear momentum, that is to say in the sense of the centrifugal forces, can be exploited. Secondly, however, the angular momentum conservation can be exploited, in which the Base learns an angular momentum when the angular momentum of the flywheel is changed. If the case of linear momentum conservation is paramount, the flywheel mass will be eccentric with respect to the rotational motion. If angular momentum conservation is paramount, the flywheel mass will be concentric with respect to the rotational spin. Here, the flywheel is meant in the sense of the center of gravity and not necessarily in their physical form. In the former case, for example, an increased acceleration of the flywheel in certain areas of the track, such as non-circular tracks such as sun gears or planetary gears could be exploited, in the second case, for example, when changing the direction of a concentric rotation of the flywheel of the angular momentum acting on the base. In both cases, clearly speaking, a "jolt" of the base can be generated, which overcomes the static friction for a certain phase of movement.

It is not absolutely necessary, albeit preferred, that the motion phases, ie the "jerking motions of the base" generated by the flywheel masses, are always substantially rectified (including rectified in the sense of rotational movements). In principle, cases are conceivable in which the static friction is also overcome in the context of "backward steps", which, however, lead overall to a smaller backward movement than the desired forward movement. Thus, for example, the flywheel mass drive could briefly overcome the static friction limit even if the inertial forces were effective in the wrong direction. If the stiction boundary is overcome in the desired direction for a longer time or at a greater speed, this is in principle not an obstacle to locomotion.

In particular, it is also particularly preferred to use components of the utilized inertial forces in order to exploit the static friction between the device and the surface on which it is intended to move. By appropriate design of the movements, in particular their inclination, the device can namely temporarily and possibly also in places heavier or lighter, to be precise so pressed by appropriate inertial forces on the surface or relieved in gravity. As a result, it is possible, in addition or as an alternative to the already mentioned use of particularly large inertial forces in certain movement phases, to distinguish between movement phases and adhesion phases. For example, in terms of amount constant inertial forces in the phases of motion due to the gravitational force lead opposite components to a sliding of the device and to stick in phases of adhesion by components acting parallel to the gravitational force.

Particularly preferred is the use of at least two momentum masses in the above sense. This allows, in addition to the aspects mentioned, a clever combination of the respective inertial forces and phase-wise addition or compensation. For example, two circularly moving centrifugal masses with eccentric center of gravity can move in opposite directions and synchronously, so that their inertial forces compensate twice per full revolution and add up twice per full revolution. By additional tilting of the planes of rotation gravitationally parallel and in the other case gravitationally antiparallel inertial force components can be generated in the phases of the addition in one case, so that the device moves jerkily only or at least stronger in the latter case.

The flywheel masses are preferably gimballed on the base in rotary components. This can serve to tilt the planes of rotation in the sense just described. Furthermore, by appropriate adjustment of the gimbals in contrast to a fixed invariable tilting also vote on the size of the static friction between the device and the surface and also a possibly necessary compensation of directional dependencies of this friction take place, for example, aligned wiping fabrics. The adjustment of the gimbal suspension is preferably carried out by motor and can in particular also be done automatically by the device, so to speak, the beginning of the motion phase tests and automatically adjusts to optimal propulsion for given rotational movements by adjusting the tilting.

In the case of a flywheel mass drive by utilizing the linear momentum conservation, thus also the centrifugal forces, it is preferred that the device moves over the surface stepwise with - in the case of a desired straight movement of the device - translational single steps. In contrast, in utilizing the angular momentum conservation, it is intended to utilize an angular momentum component acting on the base by effectively using one end of the device as a rotation axis, and although it is "weighted" by a surface-parallel angular momentum component acting on the base. In the next step, an opposite end of the device may serve as a rotation axis and an oppositely directed and base-acting angular momentum, ie, a component perpendicular to the surface, may be used for a corresponding second step. The device would thus in this case, for example, with a right and a left side alternately stepwise, while each rotate about the other side. The angular momentum components can be generated either by tilting rotating gyros or, less preferably, by accelerating or decelerating such gyros.

Incidentally, the device need not necessarily be free from other drive or steering influences. For example, in the case of the preferred use as a cleaning device, it may also be desirable to provide an operator influence on the movement, for example, by attaching a style for steering or also to assist in the movement. A motor-driven mop with style would make it easier for a cleaning person to push the mop over the surface to be cleaned, on the other hand, the mop could also be much heavier and thus with respect to the cleaning effect more effective than a conventional manually operated mop. However, a self-sufficient and automatically moving cleaning device with the described flywheel drive is preferred.

In FIG. 16 schematically a device 104 for wetting a wet mop 101 is shown. The wet mop 101 has a holder 102 fixed to a handle 118 for holding a mop cover 103. The mop cover 103 is flexible and absorbent, so that it can be moistened for cleaning in particular floors with a cleaning liquid.

For moistening, the wet wiper 101 is guided in the direction of the arrow by the device 104 through a guide 113, which has individual guide elements in the form of horizontally arranged sheets. The guide 113 leads the holder 102 horizontally along a horizontal trajectory over a nozzle 112 of time. The nozzle 112 is connected via a fluid line 111 to a pump 108 located at the bottom of a container 105 which forms the base of the device 104. By doing Container 105 is a cleaning liquid 106, which can be sucked by the pump 108 via an input filter 107 and pumped through line 111 to the nozzle 112. Through the nozzle 112, the liquid 106 can be injected from below against the mop cover 103 of the wet mop 101.

In the guide 113, a sensor 114 is provided, for example in the form of a switch, which detects the presence of the holder 102 in the guide 113. Once the holder 102 has been inserted into the guide 113 and this has been detected by the sensor 114, a controller, not shown, controls the pump 108, so that the liquid 106 is sprayed upwardly through the nozzle 112. At the same time a motor-driven drive roller 110 is driven, which is arranged below the movement path. On the drive roller 110 opposite side of the movement path two counter-rollers 109 are arranged, which are arranged coaxially to each other and are rotatable about an axis of rotation which is parallel to the axis of rotation of the drive roller 110. The holder 102 can thus be pulled together with the mop cover 103 between the drive roller 110 and the counter rollers 109 therethrough.

The distance between the drive roller 110 and the counter rollers 109 is dimensioned so that the holder 102 with the mop cover 103 is in frictional engagement with the rollers 109, 110, so that it can be detected and driven in a drive direction.

In FIG. 17 the part of the device 104 for squeezing the mop cover 103 is shown enlarged from the front. The drive roller 110 extends over the entire width of the mop cover 103 perpendicular to the drive direction, so that it rests on the bottom of the mop cover 103 over the entire width. The two counter rollers 109 are arranged to be disposed over the edges of the holder 102 in widthwise extension of the holder 102 and leave a gap therebetween. The space between the rollers 109 serves to pass the handle 118 of the wet mop.

As in FIG. 18 is represented by the pressure of the drive roller 110 of the mop cover 103 is again dehumidified in part, or liquid is pressed out of the mop cover 103. The extruded liquid 106 runs on an intermediate bottom 117 and from there through a dirt filter 115 back into the container 105. When passing the wet mop 101 through the guide 113, as shown in FIG FIG. 18 is shown is Thus, the mop cover 103 is sprayed from below with the cleaning liquid 106, so that the mop cover 103 moistened and dirt therein can be flushed out, and then dehumidified again in part, so that it exits on the right side of the device 104 with a defined humidity. This causes the mop cover 103 does not drip when cleaning. The controller also detects when the holder 102 releases the sensor 114 again or when the rear end of the holder 102 has passed the sensor 114 and then controls the pump 108 and the drive roller 110 for a certain period of time until the holder 102 completes through the rollers 109, 110 has been pulled through. The control of the pump 108 can also be terminated before the actuation of the rollers 109, 110.

In the FIGS. 19 to 22 different embodiments of the wet wiper 101 according to the invention are shown, the holder 102 has a flat core 119, at the edge of an edge trim 120 is arranged. The edge trim 120 may extend around the entire circumference of the core 119 in all embodiments.

In all the described embodiments, the core 119 may be formed by a metal plate. The thickness and the material properties depend on the forces acting on the holder 102 during the wiping of the mop cover 103, which in turn depend, inter alia, on the design of the device 104. The core material is further selected to be resistant to the liquids or cleaning agents used in cleaning. This applies at least to the sections of the core 119 which come into contact with the cleaning agents in question: In this case, the core 119 can also be provided with a protective layer.

In FIG. 19 the holder of a wet mop according to an embodiment is shown in section. The edge trim 120 in this case has a U-profile and is stuck with the open side on the edge of the core 119. The U-profile of the edge trim 120 is adapted to clamp on the edge of the core 119 to be none or one only to leave very small gap between the core 119 and the edge trim. The edge trim 120 completely surrounds the edge of the core 119, so that the edge trim 120 extends over the entire circumference of the edge of the core 119. In this case, the edge trim 120 may be attached as a profile, but a shock point in the edge trim 120 is usually unavoidable.

In an advantageous embodiment, however, the edge trim 120 may be formed directly on the edge of the core 119. This results in a better connection and a narrower gap between the core 119 and the edge trim 120, and in this way a seamless edge trim 120 can be achieved. For this purpose, the core 119 can be overmolded in particular with the edge trim 120, if the material of the edge trim 120 permits it. Further, the edge trim 120 may also be applied by dipping the edge of the core 119 into the corresponding liquid material which later hardens or solidifies.

The aforementioned possibilities for the production or attachment of the edge trim 120 can also in the following embodiments in the FIGS. 20 to 22 be applied.

In the embodiment according to Fig. 19 The edge trim 120 also protrudes downwards at the edge of the core 119 and thus prevents a flat underside of the holder 102. The mop cover 103 is thus pressed down more strongly at the edges of the holder 102. This can be prevented by making the mop cover 103 thinner and / or more compressible at the appropriate locations.

In FIG. 20 is a further embodiment shown in which the edge trim 120 basically the same configuration as in the embodiment according to Fig. 19 has. The edge of the core 119 in this embodiment is made thinner in the area where the core 119 is covered by the edge trim 120. The edge is made thinner by the thickness of the material of the edge trim 120. The holder 102, which is composed of the core 119 and the edge trim 120, thus has over its entire surface a constant thickness. This has the effect that a flat surface acts on the mop cover 103 from above and exerts a constant surface pressure during wiping. Furthermore, a constant surface pressure on the mop cover 103 can be exerted with less effort even when pressing the mop cover 103, when the holder 102 has a constant thickness over the surface.

Furthermore, in FIG. 21 another embodiment shown in which the edge trim 120 covers the core 119 only on the sides. The edge trim 120 protrudes not above or below the top or bottom of the core 119, so that the core 119 can be made the same thickness over its entire area and yet the retainer 102 has a constant thickness over its surface when the height of the edge trim 120 is the height of the core 119 is adjusted. For attachment, a notch is formed in the illustrated further embodiment in the end faces of the core 119 along the entire circumference, in which a projection extends horizontally into it, which is formed on the core 119 facing side of the edge trim 120. The projection in turn may have flexible clamping projections to be clamped for attachment in the notch can. In addition, this projection for clamping in the notch can also be made hollow and compressible.

In FIG. 22 another embodiment is shown in which the edge of the core 119 on the upper side and the lower side in particular has circumferential recesses into which the edge trim 120 extends with downward or upward projections. The edge trim 120 engages around the edge of the core 119 as in the embodiment according to FIG. 19 , In addition, the edge of the core 119 that is recessed from the top trim 120 up and down, so that the thickness of the core 119 remains constant along with the edge trim 120 overlapping the core 119 in the edge region. This results in the advantage that the height of the holder 102 remains constant and that in addition the edge trim 120 is better attached to the core 110.

Another embodiment is in FIG. 23 illustrated in which the edge trim 120 completely surrounds the core 119 and thus also extends over the bottom and the top thereof. This causes the core 119 to be completely enclosed and free of corrosive environmental influences. The core 129 can also be made of materials which are attacked by the substances acting on the wet mop 101 during operation. The material of the core 119 must have only the required strength in this embodiment. The core 119 is preferably encapsulated by the edge trim 120 or its material, resulting in a seamless envelope. The core 119 may consist of a metal and the edge trim 120 made of a plastic which is suitable for injection molding.

In FIG. 24 Another embodiment of the present invention is shown in which the edge protection is achieved by a protruding mop cover 103, which forms a damper for the core 119 as soon as the holder 102 abuts an obstacle, since the holder first the obstacle with the protruding edge of the obstacle Mop cover 103 touched. In addition, the edge of the mop cover 103 bulges in an abutment against an obstacle usually upwards and thus gets between the obstacle and the core 119, so that there is an additional damping of the impact.
