Abstract

The invention relates to a method for operating a surface-cleaning head (1) and a surface-cleaning head (1) for carrying out said method. The labour-saving application saves time and money and is particularly suitable for people who are particularly sensitive to dust. The surface-cleaning head (1) is displaced at least once in a first and a second mopping direction (11, 12), which are at least essentially opposed to one another, over the surface to be cleaned and is tilted onto a respective independently integrated front-line cleaning element (3, 4) in each of its two displacement directions. The cleaning head is tilted onto the front-line cleaning element (e.g. 3) of the two parallel front-line cleaning elements (3, 4), (which lie mirror-symmetrically opposite one another, forming a recessed gap (6) between them), that is the respective rear front-line cleaning element (e.g. 3) in relation to the mopping direction (e.g. 11). In addition, each front-line cleaning element (3, 4) lies at a deployment angle (7) that points rearwards from a perpendicular in relation to the respectively allocated mopping direction (11, 12). As a result of said angle, the two front-line cleaning elements (3, 4) extend away from the cleaning head (1) at an increasing distance from one another.

Method for operating a surface cleaning head and surface cleaning head for performing the method

The invention relates to a method for operating a surface cleaning head according to the preamble of claim 1 and a surface cleaning head for carrying out the method according to the preamble of claim 4.

For cleaning, for example, floor surfaces by wiping are different types of equipment are known, for example, rubber lip wiper whose rubber lip forms a kind of cleaning front line element. To clean a surface in question, this device is moved in a single direction over the surface to be cleaned.

Other types of surface cleaning devices have a plate-shaped surface cleaning head, which is moved to clean a surface to be cleaned, where appropriate, in different directions back and forth over the surface to be cleaned. However, such a surface cleaning head is always on a surface, namely with its entire plate surface, on. The presence of a cleaning front-line element can therefore not be discussed in the case of such surface cleaning heads. For cleaning serves, as I said, the entire overlying plate surface. In this context, those edges of the plate-shaped surface cleaning head, which are located at the frontmost point relative to a respective wiping direction, can at most be regarded as existing cleaning line elements. During cleaning, the dirt, as far as the dirt is fixed by the surface cleaning head, mainly deposits on these foremost edges. However, these edges are saturated with dirt very quickly, with the consequence that further accumulated dirt is then transported only to the culmination points of the wiping movements, where it then remains lying. The dirt is then no longer collected, but pushed apart.

This situation is met by tapping with the plate-shaped lower surface of the plate-shaped surface cleaning head on the dirt accumulated on the said edges in order to bond it to the underside of the plate-shaped surface cleaning head. The further cleaning then takes place with a pressing, hard and heavy surface on the dirt. This constellation has a strong grinding effect. In addition, the flat underside of the plate-shaped surface cleaning head has no space in which the dirt could accumulate and stop. The dirt holding capacity of the flat underside is therefore very low. Also, voluminous dirt, such as a pebble, has no space under the flat underside of the plate-shaped cleaning head and must therefore be collected separately.

To overcome these problems, soft wipes are placed under the plate-shaped surface cleaning head. Although such wipes slightly increase the dirt holding capacity, the essence of the underlying problem, namely the wiping of the dirt with higher dirt accumulation and the lack of collecting bulkier dirt, but remains unchanged.

In addition, the wipes are expensive and expensive in their application. They are often to change, and if it is not particularly expensive disposable wipes, also often to clean.

In order to minimize the change and cleaning intervals, the wipes are increasingly becoming correspondingly expensive high-tech products. In order to avoid the expense of wet cleaning, dry wipes are offered, which can electrostatically attract dirt and be dusted. With you However, it is never possible to work in such a dust-free and dust-free manner as is possible with wet wipes. Dusting these towels is at least still necessary if they are used multiple times to justify the price. For allergic persons, these wipes are certainly not suitable. Overall, there is the problem with all non-disposable wipes that they have to be prepared for a next cleaning process, that is to say they have to be cleaned if the hygienic conditions are to remain acceptable.

In sum, there is a lot of money and work associated with today's cleaning equipment. This is especially true if a dust whirling up necessarily be avoided and therefore must be cleaned wet.

From the document US 1 897 726 a cleaning device for floor cleaning is known, which works with a plurality of rubber wiper elements. The cleaning device is parked with its rubber wiper elements in its function on a piece of fabric. The textile piece is releasably secured with its ends in forward and backward wiping direction of the cleaning device on the cleaning device. By the rubber wiper elements, the textile piece is stretched spread over the surface to be cleaned spreads and remains spanned spread as a function of the cleaning device. The rubber wiper elements can not only be placed perpendicular to the surface to be cleaned, but also obliquely with an inward upward inclination in the upward direction. However, it is explicitly stated in the document that a vertical position is completely sufficient. As shown particularly in FIGS. 2, 3 and 4, the said inclination is therefore only a slight inclination. In operation, the cleaning device with its rubber wiper elements, which are all simultaneously parked above the textile piece on the surface to be cleaned and always remain so parked, practiced in combination act with the always smooth spread held textile piece on the underlying surface areas of a concentrated pressure, whereby the dirt is taken from these areas.

Due to the fact that the rubber wiper elements are always always placed on the surface to be cleaned at the same time, this cleaning device ultimately works in the same way with the same disadvantages as the above-described cleaning devices with a plate-shaped cleaning head.

The document US Pat. No. 2,796,621 discloses a cleaning device with two brush elements which are arranged parallel to one another and which are always placed simultaneously on a surface to be cleaned and aligned in each case perpendicular to the surface to be cleaned. Thus, this cleaning device ultimately works again in the same way with the same disadvantages as the above-described cleaning devices with a plate-shaped cleaning head. In this case, the present cleaning device as a connection to a driving stem on an intermediate joint, through which the cleaning device with the help of the stem to turn in all directions.

From the document DE 102 21 060 Al a cleaning device is known, to the base of which a cleaning surface element is releasably secured and dosed with a cleaning liquid to moisten. Ultimately, however, this cleaning device works in the same way with the same disadvantages as the cleaning devices described above with a plate-shaped cleaning head.

The object of the present invention is, starting from a method of the type mentioned, to improve such a method in such a way that a cleaning of surfaces with minimal effort of labor, time and money feasible is, without disadvantage for people who are sensitive to dust. It is another object of the invention to provide a technically corresponding improved surface cleaning head for carrying out this method, starting from a surface cleaning head of the type mentioned.

With regard to the method, this object is achieved according to the invention by such a method which has the method steps indicated in the characterizing part of claim 1. With regard to the surface cleaning head, this object is achieved according to the invention by such a surface cleaning head having the features specified in the characterizing part of claim 4.

In the method according to the invention, a correspondingly designed surface cleaning head is moved at least once in opposite directions to one another in a first and in a second basic wiping direction over the surface to be cleaned. In this case, the surface cleaning head is tilted per basic wiping direction to a respectively associated own cleaning front line element. The cleaning front line elements are arranged transversely to the respective wiping direction. With regard to the two oppositely directed basic wiping directions, the two cleaning front-line elements are arranged one behind the other. The surface cleaning head is tilted in each case to that of the two cleaning front line elements, which is arranged by the two cleaning front line elements at the rear.

This tilting behavior collects the dirt between the two cleaning front-line elements during wiping. There is no pressure on the dirt, since no surface is pressed onto the dirt. The dirt is no longer from an outer side or outer edge of a flat

Cleaning part pushed outwards away from each other. He is rather held in the lap. This is achieved through, because at each reversal of the wiping direction of the previously collected from the last cleaning front line element collected dirt from the newly affected cleaning front line element again up and taken. Overall, therefore, there is an accumulation and not a dispersion of the dirt. It results in a kind of suction effect, by the dirt taken and kept to itself.

The surface cleaning head according to the invention has, for carrying out the above method, a second cleaning front line element, which is arranged opposite to the first cleaning front line element at least substantially mirror-inverted and formed. In addition, there is a recess forming a dome-like clearance between the two cleaning front-line elements, within which the dirt can be accumulated without pressure on it.

Each of the two cleaning front-line elements is associated with one of two basic wiping directions, which are directed opposite to each other. The cleaning front line elements are each arranged transversely to the respectively associated wiper direction. With regard to the two oppositely directed basic wiping directions, the cleaning front-line elements are mutually arranged one behind the other. In this case, each cleaning front line element is arranged obliquely rearwardly with respect to a respective perpendicular to its respective associated wiping direction at a predetermined angle. The angle is between 30 and 60 degrees. In this way, the respective cleaning front line element can slide smoothly and with effective cleaning effect over a surface to be cleaned or in other words, in this degree of adjustment of the surface cleaning head is only functional. In profile, the two cleaning front line elements are provided to each other in the manner with a deployment angle that they in Direction from the surface cleaning head are arranged away from each other.

Advantageous embodiments of the invention are the subject of dependent claims.

With regard to the method according to the invention, a dry or at least moistened wiping pad is then laid over both cleaning frontline elements in at least one single layer layer. With the wiper pad unevenness with respect to the surface to be cleaned can be compensated. It can be achieved an increased cleaning effect. The dirt can be kept completely sealed off below the wiper pad. A damp wiper pad has the advantage that the dirt can be softened and kept bound. A stirring up of the dirt is prevented. With the moisture, a detergent may be associated with the effect of increased cleaning effect. Dry wiping pads have the advantage that moisture can be absorbed with them. Again removable fasteners for the wiper pads have the advantage that the wiper pads can be easily replaced.

For the surface cleaning head according to the invention, it is particularly advantageous if the respective deployment angles of the cleaning front line elements are each selected the same with a degree value between 40 and 45 degrees. If the angles are equal, each of the cleaning front line elements can serve as a first wiping element with the same effect with respect to a single wiping operation, that is, the surface cleaning head can readily be turned in between to ultimately utilize both cleaning frontline elements evenly distributed. With a degree setting of 40 to 45 degrees, an optimal utilization of the surface cleaning head is achieved. If experience has shown that tilting of the surface cleaning head in one direction or the other is approx. 22.5 degrees, the surface remains chenreinigungskopf then still facing a surface to be cleaned by 22.5 degrees in the wiping direction forward tilted or issued to the rear.

Advantageous embodiments of the cleaning front line elements are rubber lips, brush structures, foam lips or corresponding embodiments. The at least slightly elastic materials help to compensate for unevenness of the surface to be cleaned resiliently.

Again releasable fastening means have the particular advantage that used wiper pads can be changed, but also be kept in the use itself.

A coupling structure on the surface cleaning head has the advantage that a stalk-like part can be coupled to the surface cleaning head, in particular in such a way that moving the surface cleaning head at least according to the cleaning front line elements respectively associated wiping directions and tilting of the surface cleaning head on each of The cleaning front line element belonging to the respective wiping direction is possible.

In this case, a coupling can be realized in such a way that a lateral tilting of the handle-like part relative to the

Surface cleaning head transverse to the direction of tilting of the surface cleaning head on one of the respective cleaning front line elements, caused by an up or down movement of the handle-like part, is also possible.

It is particularly advantageous if a) rapid locking and rapid loosening of the locking between the surface cleaning head and the handle-like part, b) in the loosened state of locking a free up and down movement of the handle-like part with respect to the surface cleaning head, including a tilting of the stalk-like part over the head of the plane c) in the locked state of the lock, a coupled up and down movement of the handle-like part and the surface cleaning head and thereby tilting the surface cleaning head on one or the other cleaning front line element.

With a comparison with the surface cleaning head shallow employee stalk-like part can be wiped, for example, below lower parts. In addition, the cleaning device can be adapted to the body size of a user.

The term stalk-like part is to be understood as a structure, as is known, for example, from a broomstick. However, it is also possible to use an ergonomically shaped handle in order to make it possible to lower the handle maximally flat to the surface to be cleaned, without adversely affecting the functionality of the surface cleaning head.

Also, the length of the stem-like part can be chosen differently. For cleaning, for example, window surfaces, a shorter stalk-like part may be cheaper.

A particularly rapid locking or loosening of the lock in the coupling between the surface cleaning head and the handle-like part can be realized for example by a rotational movement of the handle-like part in the one or the other direction. However, this function could for example also be realized by a lever mechanism or another mechanism.

It is also particularly advantageous if the handle-like part is optionally attachable or detachable on the surface cleaning head. Without a stalk-like part of the surface cleaning head can also be used by hand alone. A wiper pad completely wicks away the dirt and increases the cleaning effect. In addition, surface irregularities are compensated. These effects are improved when the wiper pad has several layers. In particular, several layers can also be advantageous if the wiping pad is paper-like, for example, a cheap kitchen roll paper often used today, which has a sufficiently high tear strength even when wet. A particular advantage of the surface cleaning head according to the invention is just that he can be used with such simple papers, in the wet or dry state .. Expensive mop pads are therefore not necessary, although they can in principle also be used.

It is also particularly advantageous if the surface cleaning head has a main body in communication with the cleaning front line elements, within which a liquid receiving space with means for the possibility of supplying liquid into the liquid receiving space is formed. In this case, the liquid receiving space with a liquid distribution system with the possibility of metered distribution of liquid taken from the liquid receiving space at locations in the wiping direction in front of a cleaning front line element and / or at locations between the cleaning front line elements and / or at locations directly on the cleaning front line elements coupled. The liquid can be concentrated or diluted to be a special cleaning agent.

If the cleaning front line elements at the respective lateral ends in the respective outer free corners at least substantially acute tapered formed and optionally rounded in the conclusion forming corners themselves, this has the advantage that with the surface cleaning head movement completely into corners inside without premature abutment of other edges of the cleaning front line elements can be accomplished. In addition, this is also a Protection against damage of walls by such edges when cleaning in corners given.

It is also possible to make the pointed inlet of the cleaning front-line elements even more steeply or even several times more steeply each time, so that the corner itself does not react too sensitively to bending when it is cleaned with them in blunted corners.

An embodiment of the invention will be explained in more detail with reference to a drawing. Show:

FIG. 5 shows a surface cleaning head according to FIGS. 2 or 3 in a second application situation,

FIG. 6 shows a surface cleaning head according to FIGS. 2 or 3 with a handle of the second type in a first setting position,

FIG. 7 shows a surface cleaning head with a handle second, which is basically the same according to FIGS. 2 or 3

Art in a second setting position and with an improved body, and Figure 8 shows a surface cleaning head according to Figures 2, 3,

4, 5, 6 or 7 in plan view.

The surface cleaning head 1 shown in greater detail in FIG. 1 in process steps A) to G) has a central part Basic body 2, to which two cleaning front-line elements 3, 4 are attached.

The cleaning front line elements 3, 4 are parallel to each other attached to the main body 2. They have an elongated extension with a rectangular profile according to the embodiment. If necessary, this profile could also be different in the course of optimization measures. The rectangular profile is the simplest solution and is provided, for example, by rubber lips, which are used, for example, in rubber wipers.

For holding the cleaning front line elements 3, 4 are held in rubber lip holders 5 according to the embodiment. The rubber lip holder 5 in turn are firmly connected to the base body 2. Other types of attachment of the cleaning front line elements 3, 4 on the base body 2 are conceivable.

Between the two cleaning front line elements 3, 4 is a free space forming recess 6 is present. The recess 6 is formed according to the embodiment over the entire longitudinal extent of the cleaning front line elements 3, 4. The recess 6 forming the said free space can be provided by the fact that the cleaning front line elements 3, 4 on their own already protrude over the edge of the main body 2, as in the exemplary embodiment of the case. Otherwise, this free space could also be provided in whole or in the case of a supplementary measure partially by a recess 6 extending into the main body 2.

Each of the cleaning front line elements 3, 4 is assigned one of two mutually oppositely directed wiping directions. In this case, each cleaning front line element 3, 4 with respect to a perpendicular to its respective associated wiping direction, a rearwardly directed deployment angle. 7 on. By the respective rearwardly directed deployment angle 7, the two cleaning front line elements 3, 4 to each other in the direction of the surface cleaning head 1 away from each other, that is arranged in an opening manner.

Attachment means 8 for releasably securing a wiper support 9 (FIG. 1B) which can be placed over the cleaning front-line elements 3, 4 are attached to the main body 2. In this case, these fasteners 8 may be under spring tension, for example, so that the fastening means 8 are held resiliently closed. The spring tension can be applied in such a way that an over-center effect is achieved, that is, the fastening means 8 are kept open in the open state under bias and closed under bias in the closed state.

The fastening means 8 can be, for example, hook-like structures 10 (FIG. 8), but they can also be realized, for example, by an angle rail which is correspondingly angled in the profile and which is stretched parallel to all or part along a cleaning front-line element 3, 4. An angle rail has the advantage that an attachment of the wiper support 9 is realized over a correspondingly long line course with a correspondingly increased fastening effect.

In the figure 1 procedural steps are outlined in sections A) to K), showing how the surface cleaning head described above is applied. If necessary, activities can actually be carried out in other procedural steps as well. The process described here is only an indication of how the process works in principle. The representation must not be understood in such a way that the process works exclusively and only exactly in this way. In method step A), the fastening means 8 are opened.

In step B), the surface cleaning head 1 is placed on a dampened, slightly dry pressed and unfolded kitchen roll paper, which forms the wiper support 9. It is conceivable that the wiper pad is also applied in several layers of layers, if it should be necessary and a single layer layer is possibly too thin. It could also be used in a given case equal to a thicker wiper pad.

The kitchen roll paper or the wiper support 9 is dimensioned such that it covers the one hand by the cleaning front line elements 3, 4 spanned surface and on the other side of each of the respective cleaning front line elements 3, 4 such a supernatant that an intervention in the Fastener 8 is possible.

After the surface cleaning head 1 is placed on the kitchen roll paper or the wiper support 9, the lateral projections of the kitchen roll paper or the wiper support 9 are brought into engagement with the fastening means 8 and the fastening means 8 in the closed position.

In process step C), cleaning is started. For this purpose, the surface cleaning head 1 is placed on one of its cleaning front line elements, e.g. 3 and moved into the wiping direction 11 assigned to this cleaning front line element 3.

Subsequently, in method step D), the surface cleaning head 1 is tilted onto the other cleaning front line element, for example 4, and moved into the wiping direction 12 assigned to this cleaning front line element 4. In this case, this direction of movement is aligned opposite to the first-mentioned direction of movement. During these movements, the dirt 13 collects in the free space between the two cleaning front line elements 3, 4 present through the recess 6.

The reciprocating movements according to method steps C) and D) can be performed as often as desired. It is also possible that in between a cleaning front line element 3, 4 also several times in succession alone according to the associated wiping direction 11, 12 is moved. Thus, this cleaning front line element 3, 4 is used almost like a broom.

In the space between the cleaning front line elements 3, 4 dirt 13 may be collected on a large scale and / or in larger granular type.

Conveniently, the cleaning front line elements 3, 4 are moved in the wet state. There is such a relationship between a respective cleaning front line element 3, 4 and a respectively associated wiping direction 11, 12, that the surface cleaning head 1 in each case to such a cleaning front line element, for. 3 tilted and in such an associated wiper direction, for. 11 is moved so that the respective cleaning front line element is moved e.g. 3 around the cleaning front line element e.g. 3 of the two cleaning front-line elements 3, 4, which in wiping direction e.g. 11 is the rear cleaning frontline element.

In process step E), the cleaning process is completed. The dirt 13 lies between the cleaning Frontlinienele- elements 3, 4 and is covered by the kitchen roll paper or the wiper support 9 and held together. In method step F), the fastening means 8 are opened and the supernatants of the kitchen roll paper or the wiper support 9 are uncovered.

In step G), the surface cleaning head 1 is then lifted.

In method step H), the kitchen roll paper or the wiper support 9 is gathered together, including the dirt 13.

In method step I), for example, one end of the kitchen roll paper or the wiper support 9 is pushed under the other end.

In process step J), the gathered kitchen roll paper or the wiper support 9 together with the dirt 13 is lifted off the surface to be cleaned.

Finally, in process step K), the kitchen roll paper lifted off with the dirt 13 or the wiping support 9 lifted off with the dirt 13 are disposed of in a waste container 14.

In the figure 2, the surface cleaning head 1 with a

Stem 15 coupled. With the help of the stem 15, the surface cleaning head 1 can be moved in the desired wiping directions 11, 12. As a connecting member between the surface cleaning head 1 and the stem, a coupling structure 16 is provided.

As Figure 3 shows in more detail, the coupling structure 16 is formed in such a way that a quick locking and a rapid loosening of the locking between the surface cleaning head 1 and the stem 15 is possible. In addition, in the relaxed state of the locking between the handle 15 and the surface cleaning head 1 is compared to the surface cleaning Head 1 free up and down movement of the stem 15 possible. Depending on the design of the coupling structure 16, even a complete tilting of the stem 15 over the head of the surface cleaning head 1 may be possible from one side of the surface cleaning head 1 to the other side.

As shown in more detail in Figures 4 and 5, the coupling structure 16 is also formed in such a way that in the locked state of the locking between the handle 15 and the surface cleaning head 1 a coupled up and down movement of the stem 15 and the surface cleaning head 1 for Bewerkigungung a tilting of the surface cleaning head 1 on one or the other cleaning front line element 3 or 4 of the existing cleaning front line elements 3, 4 is possible. Depending on which cleaning front-line element 3 or 4 has been tilted, it is then possible in each case to move the surface-cleaning head 1 into the corresponding respectively associated wiping direction 11 or 12.

The length of the stem 15 may be different.

The coupling structure 16 may be further formed in such a way that the locking on the one hand and the loosening of the locking on the other hand, the locking between the surface cleaning head 1 and the stem 15 by a rotary movement (Figure 3) in one direction on the one hand and by a rotational movement in the other direction is to be accomplished on the other hand. In addition, the coupling structure 16 may be formed in such a way that, depending on or independent of such a rotational movement for loosening or locking the locking of the stem 15 on the surface cleaning head either quick to install or remove quickly.

As can be seen from Figures 6 and 7, the stem 15 may also be angled ergonomically, for example, that the stem 15 can be moved a maximum far down, without the Tilting control of the body 1 by the stem 15 thereby adversely affect.

As FIG. 7 shows in more detail, for example, the base body 2 can be designed in such a way that, within the

Body 2, a liquid receiving space 17 is provided with means 18 for supplying liquid into the liquid receiving chamber 17 and with a liquid distribution system 19 for distributing liquid received from the liquid receiving space 17 at locations 20 in the wiping direction in front of a cleaning front line element 3, 4 and / or at locations 21 between the cleaning front line elements 3, 4 and / or at points 22 directly to the cleaning Frontlinien- elements 3, 4, for example, inside.

Figure 8 shows a surface cleaning head 1 with stem 15 in a plan view. It can be seen in particular that the cleaning front-line elements 3, 4 are formed at the respective lateral ends in the respective outer free corners 23 at least substantially tapering at an acute angle.

Not shown in more detail in FIG. 8, a further embodiment of the corners 23 of several possible further embodiments may be such that the outermost tips of the corners 23 are slightly rounded or tapered at a slight acute angle.
