The invention relates to a hand-held cleaning device with a handle and an electric motor driven cleaning element.

Cleaning devices of the type in question are known in various configurations, in particular for use in the household sector, more preferably for the care and / or cleaning of surfaces in the overground area. Such a cleaning device is for example from the DE 10235123 A1 known. This has at least one electric motor drivable cleaning element in the form of a rotatably driven brush, by means of which device preferably textile surfaces, such as padding surfaces are cleaned.

In view of the known prior art, the invention has the object to improve a cleaning device of the type in question in an advantageous manner on.

A possible solution to the problem is given according to a first inventive concept in a cleaning device, in which is geared to that the cleaning element is a circumferential over two deflecting cleaning cloth and that the deflecting elements are arranged in a support member and that the support member is pivotable relative to the handle , According to this embodiment, a cleaning device is specified, which is characterized in particular in terms of handling in the course of cleaning or care of surfaces. When the cleaning device is activated, the cleaning cloth is preferably driven in a continuous, tread-belt-like manner, whereby, according to the cloth movement, a wiping and / or polishing and / or brushing effect is achieved on or at the surface to be cleaned or maintained. The deflecting elements for the cleaning cloth having support member is preferably arranged pivotable relative to the handle, so that in handling technology favorable way an adjustment of the cleaning surface is reached to be cleaned or to be cared for area. Thus, further preferably without or with only slight change in the position of the cleaning device holding and leading hand adaptation of the cleaning surface to be cleaned or maintained surface by the deflecting elements and thus the cleaning cloth having support member is adjusted to pivot relative to the orientation of the handle This is further preferred with further electromotive driving of the cleaning cloth.

Further features of the invention are explained below, also in the description of the figures, often in their preferred association with the subject matter of claim 1 or with features of further claims. But they can also be in an assignment to only individual features of claim 1 or the respective further claim or each independently of importance.

Thus, it is provided in a further preferred embodiment that the handle extends substantially transversely to a circumferential direction of the cleaning cloth. This results in a convenient handling of the cleaning device. The cleaning cloth preferably runs transversely, more preferably with respect to a plan view of the device at a 90 ° angle to a main axis passing through the handle.

In a further preferred embodiment, two carrier parts are provided, each with a circumferential cleaning cloth, moreover more preferably more than two carrier parts, each with a circumferential Renigungsstuch. In any case, an even number of carrier parts is preferably provided. These carrier parts with the circulating cleaning cloths are also preferably made the same size, in particular with regard to the active cleaning surface of the cleaning cloths.

The carrier parts are pivotable in a further preferred embodiment with respect to a connecting line of central axes of the deflecting between an aligned position and a, possibly first, V-shaped position up to or beyond a parallel position in a second V-shaped position. In this case, the pivoting of one or more carrier parts preferably takes place about an axis running parallel to an axis of a deflecting element.

In a preferred embodiment, alternatively or, as further preferred, a pivoting transversely to an axis of the deflection element is possible in combination with this. As a result, a favorable adaptation of the carrier part, which carries the cleaning cloth, made possible on the surface to be cleaned.

In an aligned position of the above-described connecting lines of the carrier parts, a total of at least approximately planar cleaning surface extending over at least both carrier parts preferably results, in particular for cleaning or for maintaining planar surfaces. In a parallel position of the carrier parts, in particular the connecting lines of the center axes of the deflecting elements and thus more preferably also in a parallel alignment of the cleaning surfaces of the cleaning cloths (which are preferably opposite in this position), for example, a two-sided cleaning of disc-like objects is possible.

All other positions between the possibly first aligned position and the parallel position or the parallel position and a possibly second aligned position result in a substantially V-shaped position of the carrier parts or the connecting lines to each other. Angled surfaces of objects can thus be cleaned or maintained in one go by means of the cleaning device. In particular, when these surfaces merge from an initially planar configuration into said angularly angled arrangement relative to each other.

In the case of an arrangement of at least two carrier parts, it is also possible to form a carrier part rigidly. Thus, in this regard, it is preferably provided that a relative to the handle immovable cleaning element is provided. Such a cleaning element is more preferably a cleaning cloth, in particular a cleaning cloth corresponding to the circulating cleaning cloths of the carrier parts.

It is further preferred that the stationary cleaning element is provided in the direction of rotation of the movable cleaning elements or cleaning cloths between the movable cleaning elements. Thus, more preferably, the stationary cleaning element is arranged bridging virtually a distance range between the movable cleaning elements. In a further embodiment, the cleaning surface of this immovable cleaning element extends in a preferably common plane to the cleaning surfaces of the pivotable support members, in particular in their aligned position.

It is also provided in a preferred embodiment that the immovable, d. H. not driven by an electric motor cleaning element is relatively pivotable to the handle, further relatively pivotable to the or the support members is arranged to offer a further favorable adaptation to the abzureinigende surface also hereby.

In addition, the cleaning cloths, in particular two on both sides of the handle provided support members, move in opposite directions. Accordingly, when considering the cleaning surface, a movement of the cleaning cloths to the proximal, d. H. preferably the handle facing the end. Alternatively, a movement of the cleaning cloths results towards the distal end of the respective carrier parts. Overall, this results in a favorable handling of the cleaning device, as tendencies inherent movements of the cleaning device on the surface to be cleaned or to be maintained are avoided.

The deflecting element is preferably a deflection axis or a deflection shaft. Over this, the cleaning cloth is stretched. One of the deflecting elements is actively driven in a preferred embodiment, in particular driven by an electric motor.

For this purpose, a drive motor for a cleaning cloth is more preferably arranged in the handle. The drive of all movable cleaning cloths or cleaning elements of the apparatus preferably takes place via this one drive motor, for which purpose corresponding translation or deflection means are preferably provided. The arrangement of the drive motor in the handle proves to be technically favorable handling.

More preferably, an accumulator is arranged in the handle, in particular for the power supply of the drive motor.

In an alternative embodiment, the handle is designed in the form of a connection adapter for connecting the cleaning device to, for example, a suction hose of a conventional household vacuum cleaner. The power supply of the device, in particular of the drive motor, then preferably takes place via the suction hose.

A support member preferably has a proximal end associated with the handle and a distal end. The handle preferably has a length extending in the direction of a width of a cleaning cloth. The length may correspond to one quarter or more of the width of the width of the cleaning cloth. For example, up to a length that is adapted to the width of the cleaning cloth, or exactly corresponds to the width. But also up to a length which exceeds the width of the cleaning cloth. For example, corresponds to 1.1 to 2 times the width of the cleaning cloth.

Preferably, the handle is also at least partially overlapping to a deflection region of one or more cleaning cloths, arranged at the proximal end of a support member.

Preferably, a central, handling-favorable arrangement of the handle is provided, from which preferably the support parts extend on both sides of a main handle axis. In this case, the handle preferably further covers the gap region between the carrier parts or the circulating cleaning cloths in a projection onto a plane formed jointly by the carrier parts.

The drive is preferably transferable by means of a belt drive on a deflecting element. More preferably, the power is transmitted to the provided at the proximal end of the support member deflection. As an alternative to a belt drive, for example, a gear drive or a worm drive is possible.

The deflection of a support member are biased in a preferred embodiment in a mutually remote position, more preferably in the direction of rotation of the male cleaning cloth. Thus, a tension of the cleaning cloth on the carrier part is achieved in an advantageous manner. By relocating the deflecting elements in a position which is less distant from one another, for example removal and reassembly of a cleaning cloth is facilitated.

In addition, it is preferred that the carrier parts are biased to one another in a certain angular position. From this particular angular position, the carrier parts are more preferably pivotable by overcoming a spring force, this further preferably starting from the basic position in one direction and in the other direction. In the specific angular position (basic position) close the support members in a preferred embodiment, an angle of 90 °, more preferably an angle of 60 ° to 120 °. It is also possible in this regard, the carrier parts in the specific angular position (basic position), as well as optionally set in other angular positions, detent, which detent is preferably canceled by the user.

The pivotable support members are preferred using the device-side handle pressed by the user against the object to be cleaned or to be maintained, this under appropriate pivoting adjustment of the support members. In this regard, a hydraulic or pneumatic adjustment or cushioning of the support members is possible.

Particularly advantageous is an embodiment in which in addition to the wiping of the surface to be cleaned by the or the rotating cleaning cloths also takes place an extraction of dirt or dust particles in particular. It may be provided in this context that a suction, assigned to the proximal end of the support member is feasible. Additionally or alternatively, it can also be provided that an extraction device assigned to the distal end of the carrier part can be performed.

The suction can be carried out through the carrier cloth. But more preferably, it is outside of the carrier cloth, and thus in a possible wiping direction upstream of the carrier cloth, feasible. In particular, the extraction can be provided circumferentially with respect to an edge region of the carrier cloth. At least on one half of the border area. Half of the edge area hereby relates to a part of the edge area which results from the deflection and the part of the edge area which corresponds to the direction of movement of the carrier cloth.

With regard to the suction, a suction fan motor may be provided. The suction blower motor may, for example, be provided in the housing part of the device which preferably forms the handle at the same time. A suction mouth is preferably formed in the case of an arrangement of the suction at the proximal end between the support parts. When arranging the suction at the distal end additionally or alternatively, as already mentioned, beyond the deflection region and in the width direction beyond the edge extending between the deflection regions.

The device can also be designed as a front attachment for a vacuum cleaner, so that the suction is made possible via a connected vacuum cleaner. In this case, a separate suction fan motor can be omitted.

The cleaning cloth is preferably exposed outside the handle, d. H. more preferably on both sides of the handle, in particular both the top and ach the bottom concerning. In this context, it proves to be further advantageous if, at least on one side (with respect to the direction of rotation of the cleaning cloth), an edge of the cleaning cloth is exposed. As a result, cleaning close to the edge, in particular of surfaces, is possible.

In order to clean off or maintain particularly curved (concave or convex) surfaces by means of the circulating cleaning cloths, in a further preferred embodiment, a clamping element is provided which acts on the cleaning cloth - in relation to the direction of circulation - between the deflecting elements. The tensioning element is correspondingly part of the carrier part for acting on the cleaning cloth from the inside in the area of the cleaning cloth exposed between the deflecting elements. As a result, preferably a bulge of the otherwise rectilinearly stretched in cross section cloth section is achieved, this at a preferred tension of the cleaning cloth to the outside.

For centering the cleaning cloth on a deflecting element, in particular for securing the cleaning cloth against slipping off the deflecting element transversely to the direction of rotation, a cleaning tab preferably has a projection extending in the circumferential direction on the underside. Such a projection is formed, for example according to a thickened seam or the like. This projection preferably engages in a correspondingly positioned and formed groove or recess of the deflecting element, whereby a positive interaction of cleaning cloth and deflecting element is achieved in Achserstreckung the deflecting element.

The cleaning cloth is preferably an endless cloth, which is stretched like a tube over the two deflecting elements of a carrier part.

Alternatively, the cleaning cloth has transverse to the direction of rotation extending locking edges, with respect to which it is detachably connectable. To connect, for example, a Velcro connection is preferred, wherein a cleaning cloth end has a Velcro strap and the other cleaning cloth end a Velcro strap.

The speed of the cleaning cloth is preferably 0.3 to 0.7 m / s, more preferably about 0.5 m / s, which in a further preferred embodiment a speed of 1.5 to 3 U / m, more preferably about 2 U / s. m corresponds.

Due to the preferred counter-rotating arrangement, the device is in an equilibrium that prevents constant running away on the work surface.

As a cleaning cloth, microfiber material is preferred.

The pivotability of the carrier parts starting from a basic position is preferably +/- 60 °, more preferably +/- 45 °. The size of the entire cleaning surface corresponds to an opening angle of the support parts to each other of 180 °, preferably about 150 × 150 mm, more preferably about 190 × 100 mm, wherein the distance between the cleaning cloths in the proximal end of the support members is minimized. The distance corresponds preferably only a few millimeters, in particular 5 mm or less up to 0 mm.

The deflection elements, in particular in the embodiment of the same as deflection shaft are further preferably spanned with a foam, so as to allow an adjustment of the cleaning cloth on undulating ground.

The speed and cloth speed is variably adjustable in a further embodiment, for example via a corresponding positioned in the region of the handle switch.

Also, the cloth material may be a chamois leather or the like.

At the distal end of the support deflecting elements can be arranged with low coefficient of friction. The drive can also be done on these distal deflection elements beyond. Carrier parts can be used as shaft bearings on both sides of the cleaning cloth. By central position of the shaft drive and the associated subdivision of the axis can be achieved by storage with a ball joint a most extensive surface adaptation in this direction, so that in particular surfaces with strong curvature, such as relatively small sink, can be processed well. In order to reduce the associated higher cost of cloth change, this is further preferably a guide system for adjusting the required four circumferential cloth bands provided. Furthermore, an automatic contraction of the springs and thus a positioning of the axes facilitates the cloth change.

Alternatively to the feathering of the support parts, a two-part embodiment of the handle is provided. The upper part is in this case preferably rigid, in order to press with the heel of the hand the whole device to the surface to be cleaned. The lower part of the handle is in this case preferably arranged movably as a lever, so that this lever can be actuated with the fingertips. By the transmission of this movement by means of levers on the support members they are moved, ideally so that a small force generates a large pressing force. The pressing of the carrier parts can also be done via the housing directly from the fingertips of the user.

By choosing an optionally provided bias and suitable stops the carrier parts can be biased by the springs so that always a minimum contact force is applied to the surface.

The distance between the deflecting elements within a carrier part can also be mechanically increased or reduced by means of a toggle lever system for tensioning the attached cleaning cloth. This optionally saves a spring to be provided. In addition, the spring properties of the cleaning cloth and / or the foams can also be used. In addition, the use of another roller as a tensioner is possible.

Alternatively to the formation of a projection on the cleaning cloth, one or more elastics can be used for centering the same on a deflecting element. Further alternatively, the deflection elements are designed concave or convex, in particular in the form of rollers, so as to achieve a centering of the cleaning cloth.

The cleaning cloth is preferably single-layered. Alternatively, a multi-layered design is provided in order to achieve a better adaptation of the properties to the device and / or to the cleaning results. Thus, it is provided in a development that the foam is mounted on the inside of the cleaning cloth instead of on the deflecting element. The foam layer on the or the deflecting elements can thereby be reduced or even eliminated altogether.

Also plastic straps can be sprayed on the back of the cleaning cloth. Such plastic bands can be loosely next to each other or connected to each other by means of a film hinge. This allows the baffles, similar to gears, to engage in recesses in the bands, thereby transporting them. Thus, the cleaning cloth can also be aufgeklettet on a suitably designed cloth carrier.

In the event that such a carrier can compensate for the length tolerances by manufacturing and, for example, shrinkage of the cleaning cloth during washing, can be dispensed with the cloth tensioning device. For the cleaning cloth is always longer than the scope of such a cloth carrier, wherein one of the cloth ends, for example, in a slot in the cloth carrier is guided inwards.

In addition, a cloth carrier or carrier part can also be designed in such a way that a rectangular cloth is stretched on it and, as a result of the fact that the first and last member of the carrier are connected to one another, an endless cloth is formed again.

With regard to the disclosure, the ranges and / or ranges of values or multiple ranges given above also include all intermediate values, in particular in 1/10 increments of the respective dimension, if necessary also dimensionless, in particular 1.01-fold, etc., on the one hand, to restrict the mentioned range boundaries from below and / or above, alternatively or additionally but also with regard to the disclosure of one or more singular values from the respective specified area.
