The wiping head is used for wiping operation in the working position and wiping head centrifuges in the centrifuge position. A wiping cover (5) is arranged at the wiping head. The wiping head elements form a bearing in the centrifuge position. The bearing is placed on a bearing stage (10) provided at peripheral portion of a centrifugal basket (7). Independent claims are included for the following: (1) a centrifugal basket with an extension; and (2) a cleaning system with a wall area.

Description

The invention relates to a cleaning system according to the preamble of claim 7, which comprises a mop with a mop head and a spin basket, which is used for ejecting a mop head arranged on the mop head. The invention also relates to a spin basket for such a cleaning system according to the preamble of claim 4 and a mop head of a mop device, which is intended for use in such a cleaning system, according to the preamble of claim 1.

In recent years, increasingly cleaning systems have come on the market, comprising a wiper device and a cleaning liquid receiving container, which is associated with a spinning device with rotatably mounted spin basket. Instead of wringing the mop cover arranged on the mop head in a conventional manner, it is provided that the mop head or the mop cover arranged thereon is ejected. This allows a much higher degree of dryness than would be achievable with a wringing. In addition, these cleaning systems have the advantage that the user does not have to touch this for wetting the mop cover and thus he does not come into contact with cleaning agents or with the dirty water. The cleaning systems described above can be subdivided into different groups, each of which makes use of certain basic concepts.

A first group form cleaning systems, which relate to a container with a drive means provided on the container. The drive device is usually either an electric motor drive device or one that has a to operating foot pedal features. Such cleaning systems, for example, disclose the publications WO 2005/027707 A1 . US 4,506,403 . GB 2 469 707A or DE 20 2009 009 920 U1 , Upon actuation of the drive means, a mop head, usually rotatably connected to the handle of the mop, is rotated about the driven spin basket to remove the mop head by the generated centrifugal forces. Also the DE 10 2005 012 734 A1 , the DE 103 11 799 and the WO 92/14394 A1 disclose such devices.

In the aforementioned devices, which are used for ejecting a flat wiper, is also a disadvantage that the spinners must either take up the flat wiping head in its entire width or the height of the spinners must be at least half the width of the mop head. This often leads to the desire for a large wiper head width to a very wide or a very high-build centrifugal device. With a reduction of the spinner width or height, in turn, the mop head width would immediately have to be reduced.

A second group of cleaning systems described above relates to those in which no drive means is provided on the container itself, but for the wiper device but holds a drive device, which drives the mop head. The spin basket of the spinner is used in these systems primarily to keep the rotating mop head during ejection in a spatially defined position and prevent unwanted tumbling by centering the mop head on the axis of rotation. Examples of this type of cleaning systems disclose the DE 20 2010 011901 U1 or the originating from the applicant itself pamphlets WO 2006/114251 A1 respectively. WO 2006/114253 A1 ,

A disadvantage of these cleaning systems, however, is that the container either for receiving the drive device and / or for the purpose of storage of the spin basket must be specially designed via a bearing dome provided on the container. The containers are constructed as a result of relatively complex and expensive to manufacture. The space that must be available for drive device and / or storage of the spin basket is lost as a wiping water volume. Due to the non-uniform interior of the container of the container has inside areas that are difficult to access and therefore cumbersome to clean. Even when using the container without the spin basket apply disadvantageous restrictions, because the bearing dome, which otherwise holds the spin basket, is still extremely hindering. The wiper water volume is compared to a conventional bucket is still reduced and the bearing dome, including arranged thereon technical components, may not be seen at high level of dirty water, so that a cloth can get caught and there is a risk of injury to the user. In addition, the bearing dome or otherwise non-uniform, jagged container interior is simply a hindrance to handling.

The already mentioned WO 2006/114251 A1 and WO 2006/114253 A1 On the other hand, it is possible to provide an attachable housing on the container, at the bottom of which a spin basket is rotatably mounted. As a result, the container as such remains largely unaffected by the spinner and can in principle also be used without an attached housing.

Nevertheless, that is in the mentioned WO 2006/114215 A1 or WO 2006/114253 A1 disclosed cleaning system disadvantageous, and in particular when a flat wiper with a plate-shaped mop head is to be used as a wiper device. Because in the disclosed solution, the wiper device during the discharge process is placed on a support provided remote from the spin basket support. As a result, the largely free-hanging part of the mop head and the mop cover is guided only insufficiently centered and staggering during ejection may or may cause an unnecessarily large imbalance. However, a resulting shaking of the container during ejection should be avoided.

In addition, the remote arrangement of the support step from the spin basket means that the housing must fully support the forces exerted on the handle of the wiper to produce the rotary motion and the unbalanced side-acting inertial forces to a great extent, even though the top-side housing surface is always flat aspired low weight of the components should be rather thin. There is therefore a fast risk that the housing will be greatly deformed upon actuation of the wiper for a Ausschleudervorgang and leaves a poor quality impression with still acceptable weight and material usage. In addition, finally, a support step provided high up on the housing has an unfavorable leverage with respect to side-acting operating forces and unbalanced mass forces, which unnecessarily aggravates jarring of the container during ejection. In addition, in addition, a support disposed above the spin basket supports must be connected via support struts or the like with the container. However, this reduces the accessibility of the spin basket and makes it more difficult to insert the mop head and mop cover into the spin basket.

The object of the invention is therefore to provide a cleaning system comprising a mop with a mop head and a spin basket, a spin basket for such a cleaning system and a mop head of a mop, which is intended for use in such a cleaning system, and the known cleaning systems To improve centrifugal and wiper devices with a view of the overall system and to largely eliminate the mentioned disadvantages of the prior art.

In particular, a cleaning system is to be created that allows the use of a standard container without bearing domes or other possibly interfering with the use of facilities for receiving drive devices that minimize the filling volume. The structural design of both the cleaning system itself and the tools required for its manufacture should be simplified in order to minimize development and production costs. The possibility of using a standard container should also be used to design the cleaning system and in particular its components as parts of a system solution in which various components of the system solution are interchangeable and on the same standard container different types Entnässungssysteme be placed. Furthermore, the cleaning system to be created is intended to minimize the disturbing shaking during the discharge process, to ensure easy and safe operation, a high-quality impression of quality and a more convenient handling.

These objects are achieved with respect to the cleaning system in that the mop head has a mop plate with a center plate and hinged hinged side plate wings, the support is formed with folded plate wings of the center plate or of the plate wings and the Auflagerstufe on which the center plate or the plate wings rest for ejection, is provided at the peripheral portion of the spin basket.

With respect to the mop head of the mop, the object is achieved by a mop head, which has a mop plate with a center plate hinged thereto and hinged side plate wings, wherein the support with which the center plate or the plate wings are able to rest on a provided on the spin basket Auflagerstufe, at folded plate wings of the center plate or of the plate wings is formed, so that the mop head can be placed on a support step, which is provided at the peripheral portion of the spin basket.

With regard to the spin basket, the invention provides that the Auflagerstufe is provided on the peripheral region of the upper side open spin basket, so that a multi-unit mop head with a center plate and hinged hinged side plate wings with folded plate wings with a support formed by the center plate or the plate wings the Auflagerstufe is placed, while the mop cover hanging in the spin basket.

It is advantageously provided that a spin basket carrier is provided in which the spin basket is rotatably mounted. The spin basket and the spin basket carrier are part of a spin attachment which can be placed on the container as a functional unit which can be separated from the container or inserted into the container. This makes it possible to use as a container for the cleaning liquid, a standard container on which in addition to the spin attachment or instead of the spin attachment, other functional parts such as alternative wringers can be used.

If the spin basket projects beyond the spin basket carrier in the vertical direction, at least the part of the spin basket projecting beyond the spin cage carrier in the vertical direction has a circumferentially closed wall region. This prevents wastewater from being thrown over the upper edge of the centrifuge basket carrier during the discharge process. Instead, it is caught by the closed wall area of the spin basket.

So that the mop cover to be thrown out does not partly lie directly against a closed wall area, it is provided that the closed wall area has an inwardly projecting ribbing, which keeps the mop cover away from the inside of the closed wall area during the discharge process. The ejected water thus enters the intermediate area and can flow down.

In order for the mop head and the spin basket to be in a centered position with respect to the axis of rotation during ejection, it is provided that the support step and the mop head are matched to one another such that the diametrically opposite regions of the support step and the mash head formed on tilted plate wings Support center the mop head in the spin basket relative to the axis of rotation. In particular, provision can be made for the support step provided on the spin basket to have a horizontal support region and a vertical centering region, the end faces of the middle part of the mop head being aligned by the vertical centering region with the axis of rotation of the spin basket. The vertical centering of the Auflagerstufe can also be funnel-shaped, which facilitates the placement of the mop head on the Auflagerstufe. For the same purpose, the outer curvature of the lateral edge of the center plate or the curvature of the bearing element provided on the plate wings to form a bearing can be adapted to the diameter or curvature of the vertical centering region of the bearing step.

Another object of the invention is as well as possible to center the mop head rotating during the discharge process and the mop cover arranged thereon in order to largely prevent shaking or even a dancing around of the cleaning system at high rotational speeds. For this purpose, it is provided that when folded down plate wings and placed on the spin basket mop head, the inner diameter of the lower part of the spin basket - ie the part of the spin basket inside, which is located laterally next to the folded plate wings - and the outer distance of the plate wings so matched in that the top surfaces of the blades are closely spaced from that of the center of the spin basket. By "closely spaced" it is meant that the plate wings are aligned substantially parallel to the adjacent inner side of the spinning cage, wherein, for example, a mop cover which extends up to the upper side of the plate leaves is located between the upper plate side and the inner side of the spinning basket with the plate leaves folded down and keeping them at a distance, is tolerable. Preferably, the plate wings are in ejection in contact with the inner lateral wall of the spin basket.

The wiper of the cleaning system described above thus preferably has a mop head, which is specially adapted to the cleaning system or the spin basket. The mop cover arranged on the mop head is removed by means of the spin basket by ejection. In order to keep the diameter of the spin basket low and thus simplify the handling of the cleaning system in the household, the mop head is formed mehrgliedrig and the mop heads are from a working position in which the mop head is used for wiping, in a spin position in which the mop head is ejected, transferable, wherein in the centrifugal position, a wiper head member forms a support which can be placed on a provided on the peripheral region of the spin basket Auflagerstufe while the mop cover and possibly further mop head members hang down in the spin basket. This can be ensured, in particular, by virtue of the fact that the wiper head member used for placement on the support step projects laterally beyond the wiper head in the spin position. As a result of the measures described above, the width of the mop head for the discharge process, and thus the spin basket diameter, can be kept low, especially in the case of flat wipers.

With a provided on the peripheral region of the spin basket Auflagerstufe a from the Schleuderkorbwandung inwardly or outwardly extending support is meant, which is located above the Schleuderkorbbodens and leaves room for it, that can be absorbed by the mop head hanging parts below the Auflagerstufe from the spin basket. The invention is characterized, inter alia, also by the fact that not the spin basket bottom itself serves as a support for the mop head, but that a different from the spin basket bottom Auflagerstufe is provided on the spin basket.

Preferably, the mop head has a multi-unit mop plate with a central part hinged thereto and hinged side plate wings, wherein with folded plate wings, the middle part or the plate wings form a support with which the mop plate or the plate wings are able to rest on a provided on the upper peripheral region of a spin basket Auflagerstufe , This embodiment can be realized in a structurally simple manner and easy to handle. In this case, for example, the horizontally oriented central part protrude laterally the folded and vertically suspended plate wings to form a support. Or, which is alternatively possible, on the plate wings a support element is provided to form a support that projects laterally with folded, vertically suspended plate wings the plate wings and the horizontally oriented middle part.

In the spin basket, which is designed for use with the cleaning system described above, in which a mop cover disposed on the mop head is skived by the spin basket, and is particularly adapted for use with a mop head described above, is at the peripheral region of the spin basket open at the top a Auflagerstufe provided, which is designed and arranged such that a wiper head member of the multi-unit wiper head can be supported on the Auflagerstufe when the wiper head members of the mop head are transferred to the centrifugal position. In particular, this is the case in a multi-unit wiping head with central part and side plate wings, in which the middle part or hinged to the middle part plate wings can rest on downwardly folded plate wings on the Auflagerstufe, while the folded down plate leaves below the Auflagerstufe protrude into the spin basket ,

The support step can be realized, in particular, by expanding or reducing at least part of the peripheral region of the is formed upwardly open spin basket. Particularly suitable is a Auflagerstufe, which is formed by a circumferential, annular extension or by a circumferential, annular reduction of the peripheral region - in particular the upper peripheral region - of the upwardly open spin basket. For this purpose, the upper, frontal edge of the upwardly open spin basket to form a support step can be formed step-shaped.

In addition, it should be noted that, as far as a mop cover is mentioned, this term can also refer to wipers other than flat or plate wipers and in particular also includes the band, strip or cord attachments for a mop.

Further features and advantages of the invention will become apparent from the subclaims and from the following description of preferred embodiments with reference to the drawings.

Fig. 2

Fig. 3

FIG. 1 and FIG. 2 show a cleaning system with a mounted on a container 1 for cleaning liquid spin attachment 2 and a specially adapted to this spin attachment 2 wiper device 3 with a mop head 4 and arranged thereon mop 5.

The spin attachment 2 comprises a spin basket carrier 6 and a spin basket 7 which is held on the bottom of the spin basket carrier 6 via a pivot bearing 8.

The spin attachment 2 is placed on the container 1 as a separately formed by the container 1 assembly. This makes it possible to use the container 1 as a standard or system container on with other essays. Thus, a cleaning system series can be created with optional attachments to be used, in each case recourse to the same standard or system bucket.

From the figures it can be seen that the mop head 4 and the spin basket 7 are adapted to each other so that the patch on the spin basket 7 mop head 4 is centered when placed over the bearing 8 and thus on the axis of rotation. For this purpose, the width of a center plate 9 formed as a central part of the multi-unit wiper head 4 and the diameter of a formed on the spin basket 7 Auflagerstufe 10 is coordinated. In addition, as shown in the figures, the edge-side curvature of the center plate 9 and the curvature of the support step 10 or the inside of the outer centering ring 21 can be matched to one another.

The support step 10 is arranged at the upper peripheral region of the spin basket 7 such that two plate wings 11, which can be folded down laterally on the center plate 9, can hang down into the spin basket 4 when the middle plate 9 rests on the support step 10. The height of the spin basket 4 or the height at which the support step 10 is located above the bottom of the spin basket 7 should therefore be matched to the height of the mop head 4, if this is in the spinning position shown in the figures, so that the hanging , structurally rigid plate wings 11 do not rest on the bottom of the spin basket 7 before the center plate 9 comes into contact with the Auflagerstufe. This embodiment also makes it possible to use the wiper heads, which are typically of different widths in practice, of different wiper device series on one and the same spin attachment 2. If in each case the same center plate dimension is used, with sufficient Spacing the Auflagerstufe 10 from the centrifuge basket bottom, the width of different mop heads over the width of the plate wings are determined.

Next FIG. 1 and FIG. 2 also shows FIG. 3 the stem 12 of in FIG. 1 and FIG. 2 shown wiper 3. The handle 12 is constructed in several parts. At the lower end it can be coupled with the wiper head 4. An upper handle part 13 is axially displaceable relative to a lower handle part 14 after unlocking a handle lock 15. In this case, a drill rod 16 secured against rotation in the upper handle part 13 drives the lower handle part 14, while the upper handle part 13 pushes the outside over the lower handle part 14. The handle lock 15 also allows the adjustment of the handle height individually for each user as well as blocking the relative mobility of the upper handle portion 13 relative to the lower handle portion 14, which is required in floor wiping for applying a rotating the wiper head in the wiping plane torque.

For the actual Ausschleudervorgang the mop head 4 by pressing a wiper head 17 in the in FIGS. 1 and 2 transferred shown spin position and placed on the spin basket 7. By unlocking the handle lock 15, the lock between the upper handle part 13 and lower handle part 14 is released. By depressing the upper stem part 13, the lower stem part 14 together with the mop head 4 and mop cover 5 is rotated. A freewheel inside the handle 12 ensures that this process is repeated to further accelerate the mop head. About the number of strokes, the user can largely determine the degree of dryness itself.

It can be seen that the cleaning system shown is distinguished by the fact that no drive connection is provided between container 1 and spin attachment 2, but that the drive power for the discharge process from the handle 12 of the wiper device via the mop head 4 or the mop cover 5 onto the spin basket 7 is transmitted. The resting on the upper edge of the spin basket 7 mop head 4, the projecting into the spin basket plate wings 11 and the mop cover 5 take the spin basket 7 in the rotation, so to speak.

The moisture contained in the mop cover 5 is thrown out of the mop cover 5 and against a closed wall region 18 of the spin basket 7 and drains into the container 1. The closed wall portion 18 is provided with an inwardly directed ribbing 23 which keeps the mop cover away from the inside of the closed wall area during the discharge process, so that the ejection and downflow of the water is not hindered. However, it is also possible to dispense with the closed wall region 18, provided that the drops possibly thrown off are either caught by the spin basket carrier 6, which also acts as a splash guard, or if the thrown-away drops are thrown out only over the edge of the container in an acceptably small amount.

The support step 10 is formed in the case shown in the figures by a step-shaped support, extending from a central basket housing 19 ribs 20 outwardly connecting the central basket housing 19 with an outer centering or support ring 21. The ribs 20 together with the support ring 21 form the support stage 10. Wetness can occur in this area between the ribs 20 on the inside of the closed wall region 18. Such a supporting step 10 serving as a support for the wiping head 4 can, of course, also be realized structurally in other ways and is not limited to the variant shown in the figures.

The mop head 4 is preferably formed symmetrically. It can be seen that the plate wings 11 are pivotally hinged via four hinges 22 on the center plate 9, which are opposite the lateral edge of the center plate far inward, ie for Stem 12 out, are placed. This ensures that after folding down the plate wing 12, the edge of the middle plate 9 forms the outermost point of the wiper head 4, so that this edge forms a suitable support on the mop head 4, with which this can be placed on the Auflagerstufe 10 on the spin basket. An embodiment of a mop head 4, not shown in the figures, can provide that the hinges are provided far outside on the center plate. Then, a support element (not shown) may be provided at the top of the handle 12 directed to the edges of the plate wings 11. This support element is slightly upwards from the mop head 4 when the mop head 4 is in the working position and, when the plate leaves 11 are transferred to the spin position, ie after the plate leaves have been rotated by approximately 90 °, they will be directed outwards and in the spin position Mop head be the furthest outwardly projecting element of the mop head, so that it can form a support with which the mop head can be placed on the Auflagerstufe the spin basket. In this case, the center plate is not directly on the Auflagerstufe, but is mounted on the Auflagerstufe the cross-plate plate indirectly on the Auflagerstufe the spin basket.
