Definitions
- the invention relates to a wet cleaning device, in particular a wet wiping device, with a cleaning roller rotatably mounted about a roller axis and a roller cover which at least partially surrounds the cleaning roller in the circumferential direction and which has at least one displaceable cover element for optionally closing and / or releasing an opening area of the roller cover.
- the invention relates to a method for operating a wet cleaning device, wherein a rotatable cleaning roller for a regeneration operation of the cleaning roller is moved away from a surface to be cleaned and at least one displaceable cover element is moved into an opening area of a roller cover that at least partially surrounds the cleaning roller in the circumferential direction.
- the DE 102 29 611 B3 discloses, for example, a wet cleaning device with a wiper body which can be driven to rotate about an axis of rotation, in which a cleaning liquid is removed from a storage tank and sprayed onto the surface of the wiper body.
- the wiping body moistened in this way is guided over a surface to be cleaned during a wiping operation, the wiper body absorbing dirt from the surface to be cleaned.
- the wiping body is increasingly covered with dirt, so that regeneration is necessary.
- the wiper body is lifted off the surface to be cleaned, surrounded with a housing that is telescopic in the circumferential direction of the wiper body and sprayed with unused cleaning fluid.
- the wiper body rotates so that cleaning fluid and dirt are expelled from the wiper body, hit the inside of the housing and are transferred to a receiving tank.
- the wiping body is lifted off the surface to be cleaned for a regeneration operation by a user of the wet cleaning device.
- the telescopic housing is also manually guided around the wiper body. This is uncomfortable because the user has to carry out a plurality of operations which require a not insignificant period of time until the roller cover is completely closed and the regeneration operation can start.
- the wet cleaning device have a first cover element and a second cover element, which can be displaced in relation to one another in relation to a circumferential direction of the cleaning roller, around the opening area to close and / or release from opposite circumferential directions.
- a transition from a wiping operation to a regeneration operation of the wet cleaning device is thus possible more quickly.
- the same also applies to a change from a regeneration operation to a wiping operation, the two cover elements likewise being simultaneously moved out of the opening area in opposite directions.
- the cover elements can, for example, each be designed as a quarter circle section, so that together they cover half the circumference of the cleaning roller.
- the roller cover can furthermore have a semicircular region which is stationary on the housing of the wet cleaning device and which additionally covers the cleaning roller in combination with the displaceable cover elements, so that complete housing is possible in the circumferential direction. Since the two cover elements are symmetrical with respect to the roller axis, the semicircular region of the housing and the cover elements can together form a circular roller cover.
- the circular shape of the roller cover enables optimal removal of the liquid or dirt within the roller cover. In addition, the circular shape is also much smaller Manufacturing effort connected as, for example, a freeform surface.
- the displaceable cover elements are coupled to the cleaning roller, in particular the roller axis, via a gear such that the covering elements can be displaced by moving the cleaning roller, and vice versa.
- This configuration enables the cover elements to be displaced relative to the opening area of the roller cover and the cleaning roller to be moved out of or into the housing of the wet cleaning device.
- the cover elements are located, for example, outside the opening area, while the cleaning roller protrudes with a peripheral partial area from the housing of the wet cleaning device, namely through the opening area of the roller cover.
- the cleaning roller In order to switch from the wiping operation to the regeneration operation, the cleaning roller is now lifted off the surface to be cleaned, for example, and is thus also displaced relative to the housing of the wet cleaning device.
- the displacement of the cover elements and the displacement of the cleaning roller are thus coupled to one another.
- a user of the wet cleaning device must therefore only initiate at most one of the displacements, namely either the displacement of the cleaning roller or the displacement of the cover elements, for example by actuating a switch.
- the displacements ie initially one of the displacements, can also be initiated automatically, for example by means of a sensor system and control which, for example, detects the degree of soiling of the cleaning roller and then automatically initiates a regeneration operation.
- a sensor system and control which, for example, detects the degree of soiling of the cleaning roller and then automatically initiates a regeneration operation.
- the gear mechanism have a cover guide link formed in a housing of the wet cleaning device, into which engaging elements arranged on the cover elements engage.
- the cover guide link can, for example, have a guide groove in which the engagement element or the engagement elements are displaced.
- early or late closing of the opening area relative to the displacement of the cleaning roller can be controlled.
- the cover guide link can initially have a relatively flat and then a relatively steeper course in order to end the closing of the roller cover before the cleaning roller has reached its final position for the regeneration operation.
- Such an embodiment is particularly advantageous in order to be able to provide a circular form of the closed roller cover.
- the transmission can of course also be designed differently, for example in the form of a gear transmission, which transmits a movement of the cleaning roller to the cover elements or transmits a movement of the cover elements to the cleaning roller.
- the cover guide link it is proposed that it have a first partial guide link, in which an engagement element of the first cover element engages, and a second partial guide link, in which an engagement element of the second cover element engages.
- the cover guide link thus has two, in particular, separately designed partial guide links for the first cover element and the second cover element.
- the partial guide links can advantageously have end stops for the respective engagement element, which define the end positions of the respective cover element in relation to the wiping operation or the regeneration operation. Care should be taken to ensure that the partial guide links of the cover elements do not cross with respect to a viewing direction in the longitudinal direction of the cleaning roller, so that the displacements of the cover elements do not interfere with one another. This can be achieved by an appropriate arrangement of the partial guide links on the housing of the wet cleaning device and by an appropriate placement of the engaging elements on the cover elements.
- the cover elements can be displaced in the circumferential direction of the cleaning roller about a common cover axis, in particular can be rotated about the roller axis.
- This configuration is particularly useful in order to achieve a symmetrical arrangement of the cover elements relative to the cleaning roller and thus to achieve the best possible removal of liquid or dirt from the roller cover.
- the smallest possible design of the roller cover and thus also of the housing of the wet cleaning device is thereby achieved.
- the cover elements are also automatically and in a particularly simple manner in a corresponding direction - in addition to the displacement of the cover elements in the circumferential direction of the cleaning roller.
- Another advantage is that the shifted cleaning roller, in particular the shifted roller axis, cannot therefore collide with the cover axis.
- the cleaning roller can be displaced relative to a housing of the wet cleaning device by means of a displacement drive.
- the roller axis be arranged on a swivel arm mounted on the housing of the damp cleaning device so that it can pivot about a swivel axis.
- the displacement drive can be, for example, an electric motor, a lifting magnet or the like.
- a pivot arm is assigned to the roller axis, which connects the roller axis to the housing of the wet cleaning device.
- This swivel arm can either be swiveled manually by the user of the wet cleaning device or automatically by the proposed displacement drive.
- the displacement of the roller axis and thus also of the cleaning roller thus takes place along a curved path which essentially has a radius which corresponds to the length of the swivel arm.
- the swivel arm carries the roller axis which is preferably oriented parallel to the swivel axis and which is thus displaced when the swivel arm is swiveled along a circular path about the swivel axis of the swivel arm.
- a lever can be varied which determines the force required to displace the roller axis.
- the housing advantageously has a roller guide link for guiding the cleaning roller during a displacement.
- the roller guide link can in turn be designed as a guide groove within the housing, into which a partial area of the cleaning roller, in particular a partial area of the roller axis, engages.
- a partial area of the cleaning roller in particular a partial area of the roller axis
- an end section of the roller axis which is connected to the swivel arm for displacing the cleaning roller, can engage in the roller guide link and be guided there along a circular section during its displacement movement.
- the roller guide link and the cover guide link are assigned to opposite end faces of the cleaning roller.
- the roller guide link is assigned to a first end face of the cleaning roller and the cover guide link is assigned to the opposite second end side of the cleaning roller, so that the guide links are formed on partial areas of the housing of the wet cleaning device which are adjacent to different end faces of the cleaning roller. It is thereby achieved that the roller guide link and the cover guide link do not overlap in the same plane, which could otherwise lead to an uncertainty in the displacement movement of the cover elements and / or the cleaning roller in the overlap region.
- the roller guide link and the cover guide link are assigned to the same end face of the cleaning roller, the cover guide link, in particular a partial guide link, being associated with an auxiliary guide link, which is related to a viewing direction in the longitudinal direction the cleaning roller is in particular designed to provide an always unambiguous guide direction for the cover element or the cover elements when the roller guide link and the cover guide link overlap.
- the cover guide link and a cover guide link in the area of both end faces of the cleaning roller, which is particularly advantageous for a uniform displacement sequence of the cleaning roller and / or the cover elements and for preventing canting during the transfer.
- the auxiliary guide link must only be assigned to such a partial guide link which overlaps with the roller guide link.
- a partial guide link which in contrast has no overlap with the roller guide link, does not require the assignment of an auxiliary guide link.
- the auxiliary guide link can have a widening in relation to this area, which is excessive compared to an engaging element of the cover element engaging in the auxiliary guide link, so that the engaging element does not abut the partial guide link and therefore the guide element is not guided by the auxiliary guide link. Last but not least, an overdetermined displacement of the cover elements is avoided.
- the cover guide link In a guide area of the cover guide link, which is the roller guide link crosses, the cover guide link is associated with the auxiliary guide link with a second guide area which is tapered compared to the previously mentioned widened guide area. Due to the tapered design of this guide area, the engagement element of the respective cover element now lies against the auxiliary guide link and can be guided through it. A shifting of the engagement element of the cover element - also through the roller guide link - is thus possible along a clear displacement path.
- the invention also proposes a method for operating a wet cleaning device, in particular for operating a previously explained wet cleaning device, wherein a rotatable cleaning roller is displaced away from a surface to be cleaned for regeneration operation of the cleaning roller and at least one displaceable cover element in one Opening area of a roller cover at least partially surrounding the cleaning roller in the circumferential direction is displaced, and wherein a first cover element and a second cover element are displaced relative to one another in relation to a circumferential direction of the cleaning roller in order to close and / or open the opening region from opposite circumferential directions.
- the displaceable cover elements are coupled to the cleaning roller via a gear so that the cover elements are displaced by moving the cleaning roller, and vice versa.
- the gear mechanism can in particular have a cover guide link formed in a housing of the wet cleaning device, into which engaging elements arranged on the cover elements engage. Furthermore, the cover elements and the cleaning roller are moved by means of the cover guide link and / or the Roller guide link and / or the auxiliary guide link as previously explained.
- wet cleaning devices are to be understood as all those devices which can exclusively or among other things perform wet cleaning. These include, on the one hand, the hand-held and automatically movable wet cleaning devices, in particular also cleaning robots and, on the other hand, also combined dry and wet cleaning devices, which can carry out both wet cleaning and dry cleaning.
- wet cleaning devices for cleaning surface areas in the sense of the invention. These include, for example, devices for cleaning windows and the like.
- Figure 1 shows a wet cleaning device 1, which is designed here as a wet wiping device with a basic device 23 and an attachment device 24.
- a handle 26 with a handle 27 is arranged on the base device 23, by means of which a user can guide the wet cleaning device 1 over a surface to be cleaned.
- the handle 26 is advantageously designed to be telescopic, so that a user can adapt the height of the wet cleaning device 1 to his body size.
- the user shifts the wet cleaning device 1 back and forth across the surface to be cleaned, alternately pushing the wet cleaning device 1 away from him and pulling it towards himself.
- the front attachment 24 has a housing 17, in which a tank (not shown) for cleaning liquid, for example water, is arranged. Cleaning liquid can be poured into the tank via a filler neck 25 become. Furthermore, a cleaning roller 2 is arranged in the housing 17 and can be rotated about a roller axis 3.
- the roller axis 3 is essentially perpendicular to a usual direction of movement of the wet cleaning device 1, in which the user alternately pushes the wet cleaning device 1 away from him and pulls it towards himself.
- the cleaning liquid can be dispensed from the tank onto the surface of the cleaning roller 2 in order to moisten it.
- the cleaning roller 2 rotates about the roller axis 3, so that the peripheral surface of the cleaning roller 2 continuously rolls on the surface to be cleaned.
- the cleaning roller 2 is usually wrapped with a cleaning covering, optionally with the interposition of an additional liquid-storing sponge body.
- the cleaning surface here is, for example, a textile cleaning cloth.
- dirt is continuously deposited on the cleaning roller 2, i. H. the cleaning surface. It may therefore be necessary to regenerate the cleaning roller 2 after a certain period of operation, wherein dirt and contaminated liquid are removed from the cleaning roller 2 during a regeneration operation.
- the cleaning roller 2 is usually rotated at a speed which is higher than the speed of the cleaning roller 2 during the wiping operation. This causes dirt and liquid contaminated with dirt to be thrown off the cleaning roller 2.
- the sprayed-off liquid can be collected and fed to a collecting container.
- Figure 2 shows a perspective view of a portion of the attachment 24 in which the cleaning roller 2 is held rotatable about the roller axis 3.
- the position of the cleaning roller 2 corresponds to the Position during a wiping operation of the wet cleaning device 1.
- the roller axis 3 is connected to a motor 30 via a drive belt 31, so that the cleaning roller 2 can be driven in rotation during the wiping operation.
- the roller axis 3 is mounted on the housing 17 of the wet cleaning device 1 so as to be pivotable about a pivot axis 16 via a pivot arm 18.
- the roller axis 3 and thus also the cleaning roller 2 can be moved from the in Figure 2 shown position during wiping into the in Figure 3 shown position are shifted during a regeneration operation.
- the pivot axis 16 can also be assigned a drive, for example an electric motor.
- the front attachment 24 has a roller cover 4, which is partly arranged in a stationary manner on the housing 17 and on the other hand has two displaceable cover elements 5, 6, which are shown in the illustration in FIG Figure 2 are shifted over the cleaning roller 2 and are therefore largely covered by this.
- the cover elements 5, 6 can be displaced about a cover axis 14, the cover axis 14 here simultaneously corresponding to the roller axis 3.
- the cover elements 5, 6 correspond to the stationary part of the roller cover 4 such that they can optionally close and open an opening area 7 of the roller cover 4.
- the cover elements 5, 6 can be displaced in relation to one another in relation to a circumferential direction of the cleaning roller 2 in the opening area 7, so that the opening area 7 can be closed or opened from opposite circumferential directions.
- the housing 17 of the front attachment 24 also has guide links for the cleaning roller 2 and the cover elements 5, 6, which guide the displacement movements when changing from a wiping operation to a regeneration operation and vice versa.
- FIG 3 shows the portion of the attachment 24 during a regeneration operation.
- the cleaning roller 2 is pivoted into the housing 17 of the wet cleaning device 1 by means of the swivel arm 18 and the cover elements 5, 6 are shifted into the opening area 7 of the roller cover 4, so that the stationary partial area of the roller cover 4 and the displaceable cover elements 5, 6 together form one form completely closed roller cover 4 in the circumferential direction of the cleaning roller 2.
- FIGS. 4 to 6 show a first embodiment of the invention, in which the housing 17 of the front attachment 24 in the region of opposite end faces 20, 21 of the cleaning roller 2 has on the one hand a roller guide link 19 and on the other hand a cover guide link 9.
- a cover guide link 9 for guiding the displacement movement of the cover elements 5, 6 is arranged in the region of the end face 20 pointing forward in the illustration, ie on the side of the housing 17 corresponding to the plan view of the figure.
- the roller guide link 19 for guiding the displacement movement of the roller axis 3 is arranged in the region of the end face 21 opposite the end face 20 on the housing 17 which, according to the illustration of the figure, lies on the back of the partial area of the wet cleaning device 1 shown.
- the view thus corresponds to the Figures 2 and 3 a view of the housing 17 from the left.
- Figure 4 shows the cleaning roller 2 in a position shifted to a surface to be cleaned, and the roller cover 4 with the displaceable Cover elements 5, 6, which are pivoted out of the opening area 7 of the roller cover 4 and are located behind the cleaning roller 2 in relation to a viewing direction, starting from the surface to be cleaned.
- the roller axis 3 is displaced via the swivel arm 18 about the swivel axis 16 in the direction of the surface to be cleaned.
- a pivot drive 15 is assigned to the pivot axis 16, which is here an electric motor, for example.
- the cover elements 5, 6 each cover a quarter circle section in the circumferential direction of the cleaning roller 2, ie each cover an angular range of 90 degrees.
- the cover elements 5, 6 are formed along the entire longitudinal extent of the cleaning roller 2.
- the cover elements 5, 6 can be pivoted about the cover axis 14, which is also the roller axis 3.
- the roller axis 3 is guided in the region of the (rear) end face 21 of the cleaning roller 2 in the roller guide link 19, which has a curvature which essentially corresponds to the pivot radius of the pivot arm 18 about the pivot axis 16.
- the housing 17 has a cover guide link 9, which forms a gear 8 for coupling the displacement movement of the cleaning roller 2 with a displacement movement of the cover elements 5, 6.
- the cover guide link 9 has two partial guide links 12, 13, each of which has a guide groove.
- An engagement element 10 of the first cover element 5 engages in the partial guide link 12, while an engagement element 11 of the second cover element 6 engages in the partial guide link 13.
- the engagement elements 10, 11 are designed as sliding blocks.
- wiping works the displacement of the cleaning roller 2 in the housing 17 and the encapsulation of the cleaning roller 2 by means of the cover elements 5, 6 for the in Figure 6 shown regeneration operation of the wet cleaning device 1 so, that the swivel arm 18 is first swiveled clockwise about the swivel axis 16 by means of the displacement drive 15.
- the end region of the swivel arm 18 carrying the roller axis 3 is displaced further into the housing 17, so that the cleaning roller 2 is also pivoted into the housing 17 at the same time.
- the displacement movement of the roller axis 3 is guided by the roller guide link 19.
- the cover elements 5, 6 are completely displaced into the opening area 7 of the roller cover 4 and the engaging elements 10, 11 have reached an end stop predetermined by the partial guide links 12, 13.
- the regeneration operation of the wet cleaning device 1 can be started, the cleaning roller 2 being rotated at high speed, for example greater than 2,000 revolutions per minute (with a roller diameter of 45 mm, for example), and dirty liquid located on the cleaning roller 2 within the roller cover 4 can be thrown off and fed to a collection container.
- the change from the regeneration operation to a wiping operation of the wet cleaning device 1 then takes place in the reverse order, whereby the swivel arm 18 is first displaced again by means of the displacement drive 15, namely based on the usual orientation of the wet cleaning device 1, towards the surface to be cleaned.
- the cover elements 5, 6 are pivoted out of the opening area 7 of the roller cover 4 again by means of the gear 8, so that the cleaning roller 2 comes to rest on the surface to be cleaned.
- Due to the shape, in particular the slope of the partial guide links 12, 13 of the cover guide link 9, a time sequence between the displacement of the cleaning roller 2 and the displacement of the cover elements 5, 6 can be predetermined. For example, due to the initially relatively small slope of the partial guide links 12, 13 (starting from the wiping operation), it is possible to first completely shift the cover elements 5, 6 into the opening area 7 before the cleaning roller 2 reaches the end position for the regeneration operation.
- FIGS 7 to 9 show a second embodiment of the invention, in which both a cover guide link 9 and a roller guide link 19 are formed on the housing 17 in the region of both end faces 20, 21 of the cleaning roller 2.
- This is particularly advantageous for a uniform displacement movement of the cleaning roller 2 and the cover elements 5, 6 and for preventing canting during the displacement movements.
- the housing 17 has in the area of at least one of the end faces 20, 21 there is also an auxiliary guide link 22, in which an additional engagement element 32 of the cover element 5 engages, the partial guide link 12 of which intersects with the roller guide link 19 (based on a viewing direction in the longitudinal direction of the cleaning roller 2).
- Such an auxiliary guide link 22 is not necessary for the partial guide link 13, since the partial guide link 13 has no overlap with the roller guide link 19.
- the auxiliary guide link 22 has two guide areas 28, 29, of which a first guide area 28 has a greater width than a second guide area 29. This means that the engagement element 32 in the guide area 28 is not guided by the auxiliary guide link 22, so that the Displacement of the cover element 5 in this area is only performed by the partial guide link 12 of the cover guide link 9. In the area of overlap of the cover guide link 9 with the roller guide link 19, on the other hand, the engagement element 32 is guided by the guide area 29, so that the engagement element 10 can pass through the overlap area in a clear displacement direction.
Description
Die Erfindung betrifft ein Feuchtreinigungsgerät, insbesondere ein Feuchtwischgerät, mit einer um eine Walzenachse rotierbar gelagerten Reinigungswalze und einer die Reinigungswalze in Umfangsrichtung zumindest teilweise umgebenden Walzenabdeckung, welche mindestens ein verlagerbares Abdeckungselement zum wahlweisen Verschließen und/oder Freigeben eines Öffnungsbereiches der Walzenabdeckung aufweist.The invention relates to a wet cleaning device, in particular a wet wiping device, with a cleaning roller rotatably mounted about a roller axis and a roller cover which at least partially surrounds the cleaning roller in the circumferential direction and which has at least one displaceable cover element for optionally closing and / or releasing an opening area of the roller cover.
Des Weiteren betrifft die Erfindung ein Verfahren zum Betrieb eines Feuchtreinigungsgerätes, wobei eine rotierbare Reinigungswalze für einen Regenerationsbetrieb der Reinigungswalze von einer zu reinigenden Fläche wegverlagert wird und wobei mindestens ein verlagerbares Abdeckungselement in einen Öffnungsbereich einer die Reinigungswalze in Umfangsrichtung zumindest teilweise umgebenden Walzenabdeckung verlagert wird.Furthermore, the invention relates to a method for operating a wet cleaning device, wherein a rotatable cleaning roller for a regeneration operation of the cleaning roller is moved away from a surface to be cleaned and at least one displaceable cover element is moved into an opening area of a roller cover that at least partially surrounds the cleaning roller in the circumferential direction.
Feuchtreinigungsgeräte bzw. Verfahren zum Betrieb eines Feuchtreinigungsgerätes sind im Stand der Technik bekannt.Wet cleaning devices and methods for operating a wet cleaning device are known in the prior art.
Die
Während des Wischbetriebs wird der Wischkörper zunehmend mit Schmutz belegt, so dass eine Regeneration erforderlich wird. Hierzu wird der Wischkörper von der zu reinigenden Fläche abgehoben, mit einem in Umfangsrichtung des Wischkörpers teleskopierbaren Gehäuse umgeben und mit unverbrauchter Reinigungsflüssigkeit besprüht. Der Wischkörper rotiert, so dass Reinigungsflüssigkeit und Schmutz aus dem Wischkörper ausgetrieben werden, auf die Innenseite des Gehäuses treffen und in einen Aufnahmetank überführt werden.During the wiping operation, the wiping body is increasingly covered with dirt, so that regeneration is necessary. For this purpose, the wiper body is lifted off the surface to be cleaned, surrounded with a housing that is telescopic in the circumferential direction of the wiper body and sprayed with unused cleaning fluid. The wiper body rotates so that cleaning fluid and dirt are expelled from the wiper body, hit the inside of the housing and are transferred to a receiving tank.
Das Abheben des Wischkörpers von der zu reinigenden Fläche für einen Regenerationsbetrieb wird manuell durch einen Nutzer des Feuchtreinigungsgerätes durchgeführt. Ebenso wird das teleskopierbare Gehäuse manuell um den Wischkörper herumgeführt. Dies ist unkomfortabel, da der Nutzer eine Mehrzahl von Handgriffen durchführen muss, welche eine nicht zu vernachlässigende Zeitspanne erfordern bis die Walzenabdeckung vollständig geschlossen ist und der Regenerationsbetrieb starten kann.The wiping body is lifted off the surface to be cleaned for a regeneration operation by a user of the wet cleaning device. The telescopic housing is also manually guided around the wiper body. This is uncomfortable because the user has to carry out a plurality of operations which require a not insignificant period of time until the roller cover is completely closed and the regeneration operation can start.
Daher ist es Aufgabe der Erfindung, ein Feuchtreinigungsgerät zu schaffen, bei welchem die Umstellung von einem Wischbetrieb in einen Regenerationsbetrieb besonders komfortabel und zeitsparend möglich ist.It is therefore an object of the invention to provide a wet cleaning device in which the changeover from a wiping operation to a regeneration operation is particularly convenient and time-saving.
Zur Lösung der vorgenannten Aufgabe wird zunächst vorgeschlagen, dass das Feuchtreinigungsgerät ein erstes Abdeckungselement und ein zweites Abdeckungselement aufweist, welche bezogen auf eine Umfangsrichtung der Reinigungswalze zueinander gegensinnig verlagerbar sind, um den Öffnungsbereich aus entgegengesetzten Umfangsrichtungen zu verschließen und/oder freizugeben. Im Gegensatz zum Stand der Technik ist es damit möglich, den Öffnungsbereich zeitgleich aus zwei verschiedenen Richtungen zu verschließen bzw. freizugeben, wodurch für ein vollständiges Öffnen/Schließen eine geringere Zeitspanne erforderlich ist als im Stand der Technik. Ein Übergang von einem Wischbetrieb in einen Regenerationsbetrieb des Feuchtreinigungsgerätes ist somit schneller möglich. Gleiches gilt ebenso für einen Wechsel von einem Regenerationsbetrieb in einen Wischbetrieb, wobei die beiden Abdeckungselemente ebenfalls zeitgleich in zueinander entgegengesetzte Richtungen aus dem Öffnungsbereich herausverlagert werden. Konkret bedeutet dies, dass beispielsweise das erste Abdeckungselement zum Abdecken des Öffnungsbereiches entgegen des Uhrzeigersinns um die Reinigungswalze verlagerbar ist, während das zweite Abdeckungselement zum Abdecken des Öffnungsbereiches im Uhrzeigersinn verlagerbar ist. Entsprechendes gilt umgekehrt in Bezug auf den Wechsel von dem Regenerationsbetrieb in den Wischbetrieb, bei welchem der Öffnungsbereich freigegeben wird.To achieve the aforementioned object, it is first proposed that the wet cleaning device have a first cover element and a second cover element, which can be displaced in relation to one another in relation to a circumferential direction of the cleaning roller, around the opening area to close and / or release from opposite circumferential directions. In contrast to the prior art, it is thus possible to simultaneously close or release the opening area from two different directions, as a result of which a shorter period of time is required for complete opening / closing than in the prior art. A transition from a wiping operation to a regeneration operation of the wet cleaning device is thus possible more quickly. The same also applies to a change from a regeneration operation to a wiping operation, the two cover elements likewise being simultaneously moved out of the opening area in opposite directions. Specifically, this means that, for example, the first cover element for covering the opening area can be moved counterclockwise around the cleaning roller, while the second cover element for covering the opening area can be moved clockwise. The same applies conversely with regard to the change from the regeneration mode to the wiping mode, in which the opening area is released.
Die Abdeckungselemente können beispielsweise jeweils als Viertelkreisabschnitt ausgebildet sein, so dass diese zusammen den halben Umfang der Reinigungswalze bedecken. Korrespondierend dazu kann die Walzenabdeckung des Weiteren einen ortsfest an dem Gehäuse des Feuchtreinigungsgerätes ausgebildeten halbkreisförmigen Bereich aufweisen, welcher die Reinigungswalze in Kombination mit den verlagerbaren Abdeckungselementen ergänzend abdeckt, so dass eine in Umfangsrichtung vollständige Einhausung möglich ist. Da die beiden Abdeckungselemente bezogen auf die Walzenachse symmetrisch ausgebildet sind, können der halbkreisförmige Bereich des Gehäuses und die Abdeckungselemente zusammen eine kreisrunde Walzenabdeckung bilden. Die kreisrunde Form der Walzenabdeckung ermöglicht dabei einen optimalen Abtransport der Flüssigkeit bzw. des Schmutzes innerhalb der Walzenabdeckung. Darüber hinaus ist die Kreisform auch mit wesentlich geringerem Herstellungsaufwand verbunden als beispielsweise eine Freiformfläche.The cover elements can, for example, each be designed as a quarter circle section, so that together they cover half the circumference of the cleaning roller. Corresponding to this, the roller cover can furthermore have a semicircular region which is stationary on the housing of the wet cleaning device and which additionally covers the cleaning roller in combination with the displaceable cover elements, so that complete housing is possible in the circumferential direction. Since the two cover elements are symmetrical with respect to the roller axis, the semicircular region of the housing and the cover elements can together form a circular roller cover. The circular shape of the roller cover enables optimal removal of the liquid or dirt within the roller cover. In addition, the circular shape is also much smaller Manufacturing effort connected as, for example, a freeform surface.
Des Weiteren wird vorgeschlagen, dass die verlagerbaren Abdeckungselemente über ein Getriebe so mit der Reinigungswalze, insbesondere der Walzenachse, gekoppelt sind, dass die Abdeckungselemente durch ein Verlagern der Reinigungswalze verlagerbar sind, und umgekehrt. Durch diese Ausgestaltung ist zeitgleich ein Verlagern der Abdeckungselemente relativ zu dem Öffnungsbereich der Walzenabdeckung und ein Verlagern der Reinigungswalze aus dem bzw. in das Gehäuse des Feuchtreinigungsgerätes möglich. Während des Wischbetriebs befinden sich die Abdeckungselemente beispielsweise außerhalb des Öffnungsbereiches, während die Reinigungswalze mit einem Umfangsteilbereich aus dem Gehäuse des Feuchtreinigungsgerätes herausragt, nämlich durch den Öffnungsbereich der Walzenabdeckung hindurch. Um von dem Wischbetrieb in den Regenerationsbetrieb zu gelangen, wird nun beispielsweise die Reinigungswalze von der zu reinigenden Fläche abgehoben und damit auch relativ zu dem Gehäuse des Feuchtreinigungsgerätes verlagert. Dies bewirkt über das Getriebe zeitgleich eine Verlagerung der Abdeckungselemente in Richtung des Öffnungsbereiches, so dass die Reinigungswalze zu Beginn des Regenerationsbetriebs bereits einerseits durch einen entsprechenden Teilbereich des Gehäuses und andererseits durch die beiden Abdeckungselemente bedeckt ist. Die Verlagerung der Abdeckungselemente und die Verlagerung der Reinigungswalze sind somit miteinander gekoppelt. Ein Nutzer des Feuchtreinigungsgerätes muss somit maximal nur eine der Verlagerungen, nämlich entweder die Verlagerung der Reinigungswalze oder die Verlagerung der Abdeckungselemente, veranlassen, beispielsweise über die Betätigung eines Schalters. Alternativ können die Verlagerungen, d. h. initial eine der Verlagerungen, auch automatisch veranlasst werden, beispielsweise mittels einer Sensorik und Steuerung, welche beispielsweise den Verschmutzungsgrad der Reinigungswalze erkennt und daraufhin selbsttätig einen Regenerationsbetrieb veranlasst. Die Verlagerung von dem Wischbetrieb in den Regenerationsbetrieb bzw. von dem Regenerationsbetrieb in den Wischbetrieb ist somit besonders komfortabel und auch zeitsparend möglich.Furthermore, it is proposed that the displaceable cover elements are coupled to the cleaning roller, in particular the roller axis, via a gear such that the covering elements can be displaced by moving the cleaning roller, and vice versa. This configuration enables the cover elements to be displaced relative to the opening area of the roller cover and the cleaning roller to be moved out of or into the housing of the wet cleaning device. During the wiping operation, the cover elements are located, for example, outside the opening area, while the cleaning roller protrudes with a peripheral partial area from the housing of the wet cleaning device, namely through the opening area of the roller cover. In order to switch from the wiping operation to the regeneration operation, the cleaning roller is now lifted off the surface to be cleaned, for example, and is thus also displaced relative to the housing of the wet cleaning device. This simultaneously causes the cover elements to be displaced in the direction of the opening area via the transmission, so that the cleaning roller is already covered on the one hand by a corresponding partial area of the housing and on the other hand by the two cover elements at the start of the regeneration operation. The displacement of the cover elements and the displacement of the cleaning roller are thus coupled to one another. A user of the wet cleaning device must therefore only initiate at most one of the displacements, namely either the displacement of the cleaning roller or the displacement of the cover elements, for example by actuating a switch. Alternatively, the displacements, ie initially one of the displacements, can also be initiated automatically, for example by means of a sensor system and control which, for example, detects the degree of soiling of the cleaning roller and then automatically initiates a regeneration operation. The shift from the wiping mode to the regeneration mode or from the regeneration mode to the wiping mode is thus particularly convenient and also time-saving.
Darüber hinaus wird vorgeschlagen, dass das Getriebe eine in einem Gehäuse des Feuchtreinigungsgerätes ausgebildete Abdeckungsführungskulisse aufweist, in welche an den Abdeckungselementen angeordnete Eingriffselemente eingreifen. Bei einer Verlagerung der Reinigungswalze werden die Eingriffselemente der Abdeckungselemente in der Abdeckungsführungskulisse geführt, so dass entweder - je nach der Verlagerungsrichtung der Reinigungswalze - ein Öffnen oder Schließen der Walzenabdeckung erfolgt. Die Abdeckungsführungskulisse kann beispielsweise eine Führungsnut aufweisen, in welcher das Eingriffselement bzw. die Eingriffselemente verschoben werden. Dabei kann je nach der Ausgestaltung der Form der Abdeckungsführungskulisse, insbesondere einer Steigung, ein relativ zu der Verlagerung der Reinigungswalze frühzeitiges oder spätes Schließen des Öffnungsbereiches gesteuert werden. Beispielsweise kann die Abdeckungsführungskulisse ausgehend von einer Verlagerungsrichtung von einem Wischbetrieb in einen Regenerationsbetrieb zunächst einen relativ flachen und dann einen relativ dazu steileren Verlauf aufweisen, um das Verschließen der Walzenabdeckung zeitlich zu beenden bevor die Reinigungswalze ihre endgültige Position für den Regenerationsbetrieb erlangt hat. Eine solche Ausgestaltung ist insbesondere vorteilhaft, um eine möglichst kreisrunde Form der geschlossenen Walzenabdeckung vorsehen zu können. Alternativ zu der vorgeschlagenen Ausbildung des Getriebes als Führungskulisse kann das Getriebe selbstverständlich auch andersartig ausgebildet sein, beispielsweise in der Form eines Zahnradgetriebes, welches eine Bewegung der Reinigungswalze auf die Abdeckungselemente überträgt oder eine Bewegung der Abdeckungselemente auf die Reinigungswalze überträgt.In addition, it is proposed that the gear mechanism have a cover guide link formed in a housing of the wet cleaning device, into which engaging elements arranged on the cover elements engage. When the cleaning roller is displaced, the engagement elements of the cover elements are guided in the cover guide link, so that either - depending on the direction of displacement of the cleaning roller - the roller cover is opened or closed. The cover guide link can, for example, have a guide groove in which the engagement element or the engagement elements are displaced. Depending on the configuration of the shape of the cover guide link, in particular an incline, early or late closing of the opening area relative to the displacement of the cleaning roller can be controlled. For example, starting from a direction of displacement from a wiping operation into a regeneration operation, the cover guide link can initially have a relatively flat and then a relatively steeper course in order to end the closing of the roller cover before the cleaning roller has reached its final position for the regeneration operation. Such an embodiment is particularly advantageous in order to be able to provide a circular form of the closed roller cover. As an alternative to the proposed design of the transmission as a guide link, the transmission can of course also be designed differently, for example in the form of a gear transmission, which transmits a movement of the cleaning roller to the cover elements or transmits a movement of the cover elements to the cleaning roller.
In Bezug auf die Abdeckungsführungskulisse wird vorgeschlagen, dass diese eine erste Teilführungskulisse aufweist, in welcher ein Eingriffselement des ersten Abdeckungselementes eingreift, und eine zweite Teilführungskulisse, in welche ein Eingriffselement des zweiten Abdeckungselementes eingreift. Die Abdeckungsführungskulisse weist somit zwei insbesondere getrennt ausgebildete Teilführungskulissen für zum einen das erste Abdeckungselement und zum anderen das zweite Abdeckungselement auf. Vorteilhaft können die Teilführungskulissen dadurch Endanschläge für das jeweilige Eingriffselement aufweisen, welche die Endstellungen des jeweiligen Abdeckungselementes in Bezug auf den Wischbetrieb bzw. den Regenerationsbetrieb definieren. Dabei ist darauf zu achten, dass sich die Teilführungskulissen der Abdeckungselemente bezogen auf eine Betrachtungsrichtung in Längserstreckung der Reinigungswalze nicht kreuzen, damit sich die Verlagerungen der Abdeckungselemente nicht gegenseitig behindern. Dies kann durch eine entsprechende Anordnung der Teilführungskulissen an dem Gehäuse des Feuchtreinigungsgerätes und durch eine entsprechende Platzierung der Eingriffselemente an den Abdeckungselementen erreicht werden.With regard to the cover guide link, it is proposed that it have a first partial guide link, in which an engagement element of the first cover element engages, and a second partial guide link, in which an engagement element of the second cover element engages. The cover guide link thus has two, in particular, separately designed partial guide links for the first cover element and the second cover element. As a result, the partial guide links can advantageously have end stops for the respective engagement element, which define the end positions of the respective cover element in relation to the wiping operation or the regeneration operation. Care should be taken to ensure that the partial guide links of the cover elements do not cross with respect to a viewing direction in the longitudinal direction of the cleaning roller, so that the displacements of the cover elements do not interfere with one another. This can be achieved by an appropriate arrangement of the partial guide links on the housing of the wet cleaning device and by an appropriate placement of the engaging elements on the cover elements.
Darüber hinaus wird vorgeschlagen, dass die Abdeckungselemente in Umfangsrichtung der Reinigungswalze um eine gemeinsame Abdeckungsachse verlagerbar sind, insbesondere um die Walzenachse rotierbar sind. Diese Ausgestaltung bietet sich insbesondere an, um eine symmetrische Anordnung der Abdeckungselemente relativ zu der Reinigungswalze zu erreichen und damit einen bestmöglichen Flüssigkeits- bzw. Schmutzabtransport aus der Walzenabdeckung zu erreichen. Darüber hinaus wird dadurch auch eine kleinstmögliche Bauform der Walzenabdeckung und damit auch des Gehäuses des Feuchtreinigungsgerätes erreicht. Zudem erfolgt damit bei einer Verlagerung der Reinigungswalze in das Gehäuse hinein bzw. aus dem Gehäuse heraus auf besonders einfache Art und Weise auch automatisch eine Verlagerung der Abdeckungselemente in entsprechender Richtung - dies zusätzlich zu der Verlagerung der Abdeckungselemente in Umfangsrichtung der Reinigungswalze. Ein weiterer Vorteil ist, dass die verlagerte Reinigungswalze, insbesondere die verlagerte Walzenachse, somit nicht mit der Abdeckungsachse kollidieren kann.In addition, it is proposed that the cover elements can be displaced in the circumferential direction of the cleaning roller about a common cover axis, in particular can be rotated about the roller axis. This configuration is particularly useful in order to achieve a symmetrical arrangement of the cover elements relative to the cleaning roller and thus to achieve the best possible removal of liquid or dirt from the roller cover. In addition, the smallest possible design of the roller cover and thus also of the housing of the wet cleaning device is thereby achieved. In addition, when the cleaning roller is moved into the housing or out of the housing, the cover elements are also automatically and in a particularly simple manner in a corresponding direction - in addition to the displacement of the cover elements in the circumferential direction of the cleaning roller. Another advantage is that the shifted cleaning roller, in particular the shifted roller axis, cannot therefore collide with the cover axis.
Es wird vorgeschlagen, dass die Reinigungswalze mittels eines Verlagerungsantriebs relativ zu einem Gehäuse des Feuchtreinigungsgerätes verlagerbar ist. Dabei wird insbesondere vorgeschlagen, dass die Walzenachse an einem um eine Schwenkachse schwenkbar an dem Gehäuse des Feuchtreinigungsgerätes gelagerten Schwenkarm angeordnet ist. Der Verlagerungsantrieb kann beispielsweise ein Elektromotor, ein Hubmagnet oder dergleichen sein. Bei dieser Ausgestaltung muss der Nutzer des Feuchtreinigungsgerätes keine manuelle Verlagerung der Reinigungswalze durchführen. Beispielsweise genügt stattdessen die Betätigung eines Schalters zum Betrieb des Verlagerungsantriebs. Alternativ kann der Verlagerungsantrieb jedoch auch - wie zuvor erläutert - vollautomatisch über eine Sensorik und eine Steuerung erfolgen. Insbesondere ist der Walzenachse ein Schwenkarm zugeordnet, welcher die Walzenachse mit dem Gehäuse des Feuchtreinigungsgerätes verbindet. Dieser Schwenkarm kann entweder manuell von dem Nutzer des Feuchtreinigungsgerätes verschwenkt werden oder automatisch durch den vorgeschlagenen Verlagerungsantrieb. Die Verlagerung der Walzenachse und damit auch der Reinigungswalze erfolgt somit entlang einer gekrümmten Bahn, welche im Wesentlichen einen Radius aufweist, der der Länge des Schwenkarms entspricht. Der Schwenkarm trägt die vorzugsweise parallel zu der Schwenkachse orientierte Walzenachse, welche somit bei einem Verschwenken des Schwenkarmes entlang einer Kreisbahn um die Schwenkachse des Schwenkarms verlagert wird. Je nach der Länge des Schwenkarmes und der Position der Walzenachse an dem Schwenkarm kann ein Hebel variiert werden, welcher die für ein Verlagern der Walzenachse benötigte Kraft bestimmt.It is proposed that the cleaning roller can be displaced relative to a housing of the wet cleaning device by means of a displacement drive. In particular, it is proposed that the roller axis be arranged on a swivel arm mounted on the housing of the damp cleaning device so that it can pivot about a swivel axis. The displacement drive can be, for example, an electric motor, a lifting magnet or the like. With this configuration, the user of the wet cleaning device does not have to carry out a manual displacement of the cleaning roller. For example, the actuation of a switch is sufficient to operate the displacement drive instead. As an alternative, however, the displacement drive can also - as explained above - take place fully automatically via a sensor system and a control. In particular, a pivot arm is assigned to the roller axis, which connects the roller axis to the housing of the wet cleaning device. This swivel arm can either be swiveled manually by the user of the wet cleaning device or automatically by the proposed displacement drive. The displacement of the roller axis and thus also of the cleaning roller thus takes place along a curved path which essentially has a radius which corresponds to the length of the swivel arm. The swivel arm carries the roller axis which is preferably oriented parallel to the swivel axis and which is thus displaced when the swivel arm is swiveled along a circular path about the swivel axis of the swivel arm. Depending on the length of the swivel arm and the position of the roller axis on the swivel arm, a lever can be varied which determines the force required to displace the roller axis.
Vorteilhaft weist das Gehäuse dabei eine Walzenführungskulisse zur Führung der Reinigungswalze während einer Verlagerung auf. Die Walzenführungskulisse kann wiederum als Führungsnut innerhalb des Gehäuses ausgebildet sein, in welche ein Teilbereich der Reinigungswalze, insbesondere ein Teilbereich der Walzenachse, eingreift. Vorzugsweise kann beispielsweise ein endseitiger Teilbereich der Walzenachse, welcher mit dem Schwenkarm zur Verlagerung der Reinigungswalze verbunden ist, in die Walzenführungskulisse eingreifen und dort während seiner Verlagerungsbewegung entlang eines Kreisabschnittes geführt werden.The housing advantageously has a roller guide link for guiding the cleaning roller during a displacement. The roller guide link can in turn be designed as a guide groove within the housing, into which a partial area of the cleaning roller, in particular a partial area of the roller axis, engages. Preferably, for example, an end section of the roller axis, which is connected to the swivel arm for displacing the cleaning roller, can engage in the roller guide link and be guided there along a circular section during its displacement movement.
Gemäß einer ersten Variante wird dabei vorgeschlagen, dass die Walzenführungskulisse und die Abdeckungsführungskulisse einander gegenüberliegenden Stirnseiten der Reinigungswalze zugeordnet sind. Gemäß dieser Variante ist die Walzenführungskulisse einer ersten Stirnseite der Reinigungswalze zugeordnet und die Abdeckungsführungskulisse der gegenüberliegenden zweiten Stirnseite der Reinigungswalze, so dass die Führungskulissen an Teilbereichen des Gehäuses des Feuchtreinigungsgerätes ausgebildet sind, welche verschiedenen Stirnseiten der Reinigungswalze benachbart sind. Dadurch wird erreicht, dass die Walzenführungskulisse und die Abdeckungsführungskulisse sich in derselben Ebene nicht überschneiden, was anderenfalls zu einer Unbestimmtheit der Verlagerungsbewegung der Abdeckungselemente und/oder der Reinigungswalze in dem Überschneidungsbereich führen könnte.According to a first variant, it is proposed that the roller guide link and the cover guide link are assigned to opposite end faces of the cleaning roller. According to this variant, the roller guide link is assigned to a first end face of the cleaning roller and the cover guide link is assigned to the opposite second end side of the cleaning roller, so that the guide links are formed on partial areas of the housing of the wet cleaning device which are adjacent to different end faces of the cleaning roller. It is thereby achieved that the roller guide link and the cover guide link do not overlap in the same plane, which could otherwise lead to an uncertainty in the displacement movement of the cover elements and / or the cleaning roller in the overlap region.
Gemäß einer zweiten Variante wird alternativ vorgeschlagen, dass die Walzenführungskulisse und die Abdeckungsführungskulisse derselben Stirnseite der Reinigungswalze zugeordnet sind, wobei der Abdeckungsführungskulisse, insbesondere einer Teilführungskulisse, eine Hilfsführungskulisse zugeordnet ist, welche bezogen auf eine Betrachtungsrichtung in Längserstreckung der Reinigungswalze insbesondere ausgebildet ist, bei einer Überschneidung der Walzenführungskulisse und der Abdeckungsführungskulisse eine stets eineindeutige Führungsrichtung für das Abdeckungselement oder die Abdeckungselemente bereitzustellen. Gemäß dieser Variante ist es insbesondere auch möglich, im Bereich beider Stirnseiten der Reinigungswalze sowohl eine Walzenführungskulisse und eine Abdeckungsführungskulisse vorzusehen, was insbesondere für einen gleichmäßigen Verlagerungsablauf der Reinigungswalze und/oder der Abdeckungselemente und zum Verhindern eines Verkantens während der Verlagerung vorteilhaft ist. Da sich durch die gleichzeitige Anordnung einer Walzenführungskulisse und einer Abdeckungsführungskulisse an demselben Teilbereich des Gehäuses (nämlich in derselben Ebene) eine Überschneidung der Führungskulissen ergibt, wird eine dadurch entstehende Undefiniertheit der Verlagerungsbewegung innerhalb des Überschneidungsbereiches durch die Anordnung der Hilfsführungskulisse kompensiert. Die Hilfsführungskulisse muss dabei nur einer solchen Teilführungskulisse zugeordnet sein, welche sich mit der Walzenführungskulisse überschneidet. Eine Teilführungskulisse, welche demgegenüber keine Überschneidung mit der Walzenführungskulisse aufweist, benötigt nicht die Zuordnung einer Hilfsführungskulisse. Solange sich das Eingriffselement der Abdeckungsführungskulisse noch in einem Führungsbereich der Teilführungskulisse befindet, welcher keine Überschneidung mit der Walzenführungskulisse aufweist, ist die Verlagerungsbewegung des Abdeckungselementes - und auch die Verlagerung der Reinigungswalze - noch klar definiert. Die Hilfsführungskulisse kann bezogen auf diesen Bereich eine Verbreiterung aufweisen, welche gegenüber einem in die Hilfsführungskulisse eingreifenden Eingriffselement des Abdeckungselementes übermäßig ist, so dass das Eingriffselement nicht an der Teilführungskulisse anliegt und somit keine Führung des Eingriffselementes durch die Hilfsführungskulisse erfolgt. Dadurch wird nicht zuletzt eine überbestimmte Verlagerung der Abdeckungselemente vermieden. In einem Führungsbereich der Abdeckungsführungskulisse, welcher die Walzenführungskulisse kreuzt, ist der Abdeckungsführungskulisse die Hilfsführungskulisse mit einem zweiten Führungsbereich zugeordnet, welcher gegenüber dem zuvor genannten verbreiterten Führungsbereich verjüngt ist. Durch die verjüngte Ausgestaltung dieses Führungsbereiches liegt das Eingriffselement des jeweiligen Abdeckungselementes nun an der Hilfsführungskulisse an und kann durch diese geführt werden. Ein Verlagern des Eingriffselementes des Abdeckungselementes - auch durch die Walzenführungskulisse hindurch - ist somit entlang einer eineindeutigen Verlagerungsbahn möglich.According to a second variant, it is alternatively proposed that the roller guide link and the cover guide link are assigned to the same end face of the cleaning roller, the cover guide link, in particular a partial guide link, being associated with an auxiliary guide link, which is related to a viewing direction in the longitudinal direction the cleaning roller is in particular designed to provide an always unambiguous guide direction for the cover element or the cover elements when the roller guide link and the cover guide link overlap. According to this variant, it is in particular also possible to provide both a roller guide link and a cover guide link in the area of both end faces of the cleaning roller, which is particularly advantageous for a uniform displacement sequence of the cleaning roller and / or the cover elements and for preventing canting during the transfer. Since the simultaneous arrangement of a roller guide link and a cover guide link on the same partial area of the housing (namely in the same plane) results in an overlap of the guide links, the resulting undefinedness of the displacement movement within the overlap area is compensated for by the arrangement of the auxiliary guide link. The auxiliary guide link must only be assigned to such a partial guide link which overlaps with the roller guide link. A partial guide link, which in contrast has no overlap with the roller guide link, does not require the assignment of an auxiliary guide link. As long as the engagement element of the cover guide link is still in a guide region of the partial guide link which has no overlap with the roller guide link, the displacement movement of the cover element - and also the displacement of the cleaning roller - is still clearly defined. The auxiliary guide link can have a widening in relation to this area, which is excessive compared to an engaging element of the cover element engaging in the auxiliary guide link, so that the engaging element does not abut the partial guide link and therefore the guide element is not guided by the auxiliary guide link. Last but not least, an overdetermined displacement of the cover elements is avoided. In a guide area of the cover guide link, which is the roller guide link crosses, the cover guide link is associated with the auxiliary guide link with a second guide area which is tapered compared to the previously mentioned widened guide area. Due to the tapered design of this guide area, the engagement element of the respective cover element now lies against the auxiliary guide link and can be guided through it. A shifting of the engagement element of the cover element - also through the roller guide link - is thus possible along a clear displacement path.
Neben dem zuvor erläuterten Feuchtreinigungsgerät wird mit der Erfindung ebenso ein Verfahren zum Betrieb eines Feuchtreinigungsgerätes vorgeschlagen, insbesondere zum Betrieb eines zuvor erläuterten Feuchtreinigungsgerätes, wobei eine rotierbare Reinigungswalze für einen Regenerationsbetrieb der Reinigungswalze von einer zu reinigenden Fläche wegverlagert wird und wobei mindestens ein verlagerbares Abdeckungselement in einen Öffnungsbereich einer die Reinigungswalze in Umfangsrichtung zumindest teilweise umgebenden Walzenabdeckung verlagert wird, und wobei ein erstes Abdeckungselement und ein zweites Abdeckungselement bezogen auf eine Umfangsrichtung der Reinigungswalze zueinander gegensinnig verlagert werden, um den Öffnungsbereich aus entgegengesetzten Umfangsrichtungen zu verschließen und/oder zu öffnen. Die dadurch erreichten Vorteile ergeben sich analog wie in Bezug auf das Feuchtreinigungsgerät zuvor erläutert. Insbesondere wird dabei auch vorgeschlagen, dass die verlagerbaren Abdeckungselemente über ein Getriebe mit der Reinigungswalze so gekoppelt werden, dass die Abdeckungselemente durch ein Verlagern der Reinigungswalze verlagert werden, und umgekehrt. Das Getriebe kann insbesondere eine in einem Gehäuse des Feuchtreinigungsgerätes ausgebildete Abdeckungsführungskulisse aufweisen, in welche an den Abdeckungselementen angeordnete Eingriffselemente eingreifen. Des Weiteren erfolgt die Verlagerung der Abdeckungselemente und der Reinigungswalze mittels der Abdeckungsführungskulisse und/oder der Walzenführungskulisse und/oder der Hilfsführungskulisse wie zuvor erläutert.In addition to the previously explained wet cleaning device, the invention also proposes a method for operating a wet cleaning device, in particular for operating a previously explained wet cleaning device, wherein a rotatable cleaning roller is displaced away from a surface to be cleaned for regeneration operation of the cleaning roller and at least one displaceable cover element in one Opening area of a roller cover at least partially surrounding the cleaning roller in the circumferential direction is displaced, and wherein a first cover element and a second cover element are displaced relative to one another in relation to a circumferential direction of the cleaning roller in order to close and / or open the opening region from opposite circumferential directions. The advantages achieved in this way result analogously to that previously explained in relation to the wet cleaning device. In particular, it is also proposed that the displaceable cover elements are coupled to the cleaning roller via a gear so that the cover elements are displaced by moving the cleaning roller, and vice versa. The gear mechanism can in particular have a cover guide link formed in a housing of the wet cleaning device, into which engaging elements arranged on the cover elements engage. Furthermore, the cover elements and the cleaning roller are moved by means of the cover guide link and / or the Roller guide link and / or the auxiliary guide link as previously explained.

Zu diesen gehören beispielsweise Geräte zum Fenster putzen und dergleichen.Basically, in the sense of the invention, wet cleaning devices are to be understood as all those devices which can exclusively or among other things perform wet cleaning. These include, on the one hand, the hand-held and automatically movable wet cleaning devices, in particular also cleaning robots and, on the other hand, also combined dry and wet cleaning devices, which can carry out both wet cleaning and dry cleaning. In addition to the usual floor cleaning devices for cleaning a floor, this also means wet cleaning devices for cleaning surface areas in the sense of the invention. These include, for example, devices for cleaning windows and the like.

Das Vorsatzgerät 24 weist ein Gehäuse 17 auf, in welchem ein Tank (nicht dargestellt) für Reinigungsflüssigkeit, beispielsweise Wasser, angeordnet ist. Über einen Einfüllstutzen 25 kann Reinigungsflüssigkeit in den Tank eingefüllt werden. In dem Gehäuse 17 ist des Weiteren eine Reinigungswalze 2 angeordnet, welche um eine Walzenachse 3 rotierbar ist. Die Walzenachse 3 steht im Wesentlichen senkrecht zu einer üblichen Bewegungsrichtung des Feuchtreinigungsgerätes 1, in welcher der Nutzer das Feuchtreinigungsgerät 1 abwechselnd von sich wegschiebt und zu sich hinzieht.The

Während eines Wischbetriebs des Feuchtreinigungsgerätes 1 rotiert die Reinigungswalze 2 um die Walzenachse 3, so dass die Umfangsfläche der Reinigungswalze 2 fortlaufend auf der zu reinigenden Fläche abrollt. Die Reinigungswalze 2 ist üblicherweise mit einem Reinigungsbelag umwickelt, gegebenenfalls unter Zwischenlage eines zusätzlich Flüssigkeit speichernden Schwammkörpers. Der Reinigungsbelag ist hier beispielsweise ein textiles Reinigungstuch. Während des Wischbetriebs lagert sich fortwährend Schmutz an der Reinigungswalze 2, d. h. dem Reinigungsbelag, an. Daher kann nach einer gewissen Betriebsdauer eine Regeneration der Reinigungswalze 2 erforderlich sein, wobei während eines Regenerationsbetriebs Schmutz und mit Schmutz beaufschlagte Flüssigkeit von der Reinigungswalze 2 entfernt werden. Dazu wird die Reinigungswalze 2 üblicherweise mit einer Drehzahl rotiert, welche höher ist als die Drehzahl der Reinigungswalze 2 während des Wischbetriebs. Dadurch kommt es zu einem Abschleudern von Schmutz und mit Schmutz beaufschlagter Flüssigkeit von der Reinigungswalze 2. Die abgespritzte Flüssigkeit kann aufgefangen und einem Sammelbehälter zugeführt werden.During a wiping operation of the

Mittels des Getriebes 8 werden gleichzeitig wieder die Abdeckungselemente 5, 6 aus dem Öffnungsbereich 7 der Walzenabdeckung 4 herausgeschwenkt, so dass die Reinigungswalze 2 auf der zu reinigenden Fläche zu liegen kommt. Durch die Form, insbesondere die Steigung der Teilführungskulissen 12, 13 der Abdeckungsführungskulisse 9 kann ein zeitlicher Ablauf zwischen der Verlagerung der Reinigungswalze 2 und der Verlagerung der Abdeckungselemente 5, 6 vorgegeben werden. Beispielsweise kann durch die zunächst relativ geringe Steigung der Teilführungskulissen 12,13 (ausgehend von dem Wischbetrieb) erreicht werden, dass erst die Abdeckungselemente 5, 6 vollständig in den Öffnungsbereich 7 verlagert werden, bevor die Reinigungswalze 2 die Endstellung für den Regenerationsbetrieb erreicht.The change from the regeneration operation to a wiping operation of the

Die Hilfsführungskulisse 22 weist zwei Führungsbereiche 28, 29 auf, von welchen ein erster Führungsbereich 28 eine größere Breite aufweist als ein zweiter Führungsbereich 29. Dies führt dazu, dass das Eingriffselement 32 in dem Führungsbereich 28 nicht von der Hilfsführungskulisse 22 geführt wird, so dass die Verlagerung des Abdeckungselementes 5 in diesem Bereich nur durch die Teilführungskulisse 12 der Abdeckungsführungskulisse 9 geführt wird. In dem Überschneidungsbereich der Abdeckungsführungskulisse 9 mit der Walzenführungskulisse 19 wird das Eingriffselement 32 demgegenüber von dem Führungsbereich 29 geführt, so dass das Eingriffselement 10 den Überschneidungsbereich in eine eineindeutige Verlagerungsrichtung durchlaufen kann.The
Die Verlagerungen der Reinigungswalze 2 und der Abdeckungselemente 5, 6 von einem Regenerationsbetrieb in einen Wischbetrieb erfolgen in umgekehrter Richtung entsprechend. Im Übrigen gelten die in Bezug auf die erste Ausführungsvariante dargestellten Verlagerungsabläufe entsprechend, welche durch die Verlagerung des Schwenkarms 18 bewirkt werden und gleichzeitig die Verlagerungen der Reinigungswalze 2 und der Abdeckungselemente 5, 6 bewirken.
