Contents of the invention

The object of the present invention is to provide a surface cleaning machine of the type described at the outset, which provides an optimized cleaning effect while being easy to operate.

According to the invention, this task is solved in the surface cleaning machine described at the outset in that, during cleaning operation, the surface cleaning machine is supported on the surface to be cleaned only via a cleaning roller unit with an axis of rotation, provided for The drive motor of the cleaning roller unit is provided with a dirty liquid tank device which is detachably arranged on the cleaning head.

Since the surface cleaning machine is only supported on the surface to be cleaned via the cleaning roller unit, a relatively simple construction of the surface cleaning machine results which can be realized with low mass.

The cleaning roller unit comprises either a one-piece or multi-piece cleaning roller with a single axis of rotation. In a multi-part cleaning roller unit, all subunits have the same coaxial axis of rotation, and during cleaning operation, all subunits rotate at the same rotational speed and in the same direction of rotation around the same axis, and drive motors drive all subunits.

Furthermore, cleaning can also be carried out in hard-to-reach areas, since the space requirement for the cleaning head can be kept small, so that the driven cleaning roller unit also acts as a support; Additional travel elements of wheels or the like.

Due to the detachable dirty liquid tank arrangement on the cleaning head, the travel distance for the dirty liquid from the cleaning roller unit to the dirty liquid tank arrangement can be kept very small, thus enabling simple feeding.

Since the dirty liquid tank device can be removed from the cleaning head, it can be emptied and cleaned in a simple manner. Dirty tank units can hold large volumes of dirty liquids including liquids. In particular, the dirty liquid tank arrangement can be removed as a whole from the cleaning head or inserted as a whole into the cleaning head, so that a high degree of filling can be achieved for the dirty liquid tank arrangement.

It is thus even possible to carry out the feeding of the dirty liquid from the cleaning roller unit to the dirty liquid tank device without a suction machine, or it is possible to provide A suction machine is required for support.

This enables an energy-saving operation of the surface cleaning machine. It is thus again possible to supply the surface cleaning machine and in particular the drive motor with electrical current from the preferably rechargeable battery arrangement. The surface cleaning machine can thus be operated independently of the grid.

Advantageously, the cleaning roller unit is or comprises a wiping roller unit. This makes it possible, in particular, to carry out wet cleaning on hard surfaces. In particular, the wiper roller unit is wetted, and by the rotation of the wiper roller unit the surface to be cleaned can then be wetted just accordingly and dirt can be partially dissolved and mechanically stripped and entrained by the rotation of the wiper roller unit.

In one embodiment, the cleaning roller unit includes a wiping roller unit and a cleaning roller unit. In particular, this arrangement is such that the cleaning roller unit is positioned upstream of the wiping roller unit relative to the normal cleaning operation. In particular, it is thus possible to carry out the sweeping process prior to the wiping process on the surface to be cleaned. In particular, the cleaning roller unit can form an additional support of the cleaning head on the surface to be cleaned.

It is advantageous if the surface cleaning machine is supported on the surface to be cleaned during cleaning operation via the wiping roller unit and the cleaning roller unit. Thus, for example, self-propelling and self-orienting cleaning heads (“cleaning robots”) can be realized in a simple manner, which are able to carry out sweeping and (wet) wiping processes on the surface to be cleaned.

Advantageously, the dirty liquid tank arrangement comprises a common receptacle (common container) for the sweeping material from the cleaning roller unit and for the dirty liquid from the wiping roller unit. The sweep is dirty fluid from the sweeper roller unit. Dirty liquid from the surface to be cleaned can correspondingly be contained by the dirty liquid tank arrangement.

Alternatively, it can also be provided that the dirty liquid tank arrangement comprises separate receptacles for the cleaning material from the cleaning roller unit and for the dirty liquid from the wiping roller unit. For example, separate receptacles for dry dirty liquid (for the cleaning material) and for wet dirty liquid (for the dirty liquid from the wiper roller unit) can be provided.

In particular, one or more receptacles (receptacles) of a dirty liquid tank arrangement for dirty liquid are releasably positioned on the cleaning head between the cleaning roller unit and the wiping roller unit. This results in a space-saving construction of the cleaning head. In particular, the cleaning head can be realized in a self-moving and self-deflecting manner.

A further supporting device is, for example, a roller unit with one or more rollers, such as with one or more sweeping rollers, and/or the supporting device is or comprises at least one roller, and/or the supporting device is at least one sliding element or Including such sliding elements. Additional supports can thus be formed. In particular, a self-moving and self-deflecting cleaning head can thus be realized in a simple manner. The supporting means may (completely or partially) provide the translational drive. The supporting device can also be used for a translational drive or an additional translational drive of the cleaning head. It can also be configured for additional or sole redirection of the cleaning head.

Advantageously, the cleaning roller unit comprises one or more cleaning rollers or sub-cleaning rollers, which are driven by the same drive motor, wherein the different cleaning rollers or sub-cleaning rollers have the same orientated axes of rotation or have differently oriented axes of rotation . This results in optimized operating possibilities, in particular also for self-propelling and self-deflecting cleaning heads. In the case of different orientations of the axes of rotation, the orientability can be achieved in a simple manner, for example via different actuation with respect to the rotational speed and/or the rotational direction.

It is advantageous if the axis of longitudinal extension of the dirty liquid tank arrangement is aligned parallel to the (in particular only) axis of rotation of the cleaning roller unit. The longitudinal extension axis of the dirty liquid tank arrangement extends between a first end side and an opposite second end side of the dirty liquid tank arrangement. It presets the longest extension of the dirty tank installation. This results in a space-saving arrangement of the dirty liquid tank arrangement on the cleaning head.

It is also advantageous if the motor axis of the drive motor is aligned transversely and in particular perpendicularly to the longitudinal extension axis of the dirty liquid tank arrangement. The motor axis of the drive motor corresponds to the rotor axis of the drive motor. The transverse orientation of the longitudinal extension axis of the dirty liquid tank arrangement results in a space-saving construction.

It is particularly advantageous if the dirty liquid tank arrangement is arranged between the cleaning roller unit and the drive motor. This results in a short feed path for feeding the dirty liquid out of the cleaning roller unit into the dirty liquid tank arrangement. It is thus again sufficient to use a suction machine with a relatively low power to suck up the dirty liquid or to be able to implement a design without a suction machine.

In one embodiment, a transmission for torque transmission is provided, which is arranged between the drive motor and the cleaning roller unit, wherein the dirty liquid tank arrangement has an upper side and a lower side, wherein the lower side faces the cleaning roller unit The cleaning roller holder, and the upper side faces away from the lower side, and wherein the transmission is guided past the upper side or the lower side of the dirty liquid tank device. A transmission provides torque transfer from the drive motor to the cleaning roller unit. The cleaning roller unit is positioned spaced apart from the drive motor. The transmission provides, inter alia, speed reduction, torque reversal and, if necessary, bridge spacing. A simple and compact construction is obtained due to the fact that the drive is guided past the underside or the top side of the dirty liquid tank. In principle, it is also possible for the transmission to be guided through a through opening in the dirty liquid tank arrangement. In contrast, a simplified detachability of the dirty liquid tank arrangement from the cleaning head and a simplified structure.

In one embodiment, the dirty liquid tank arrangement has a recess in which at least a partial region of the transmission is positioned when the dirty liquid tank arrangement is fastened to the cleaning head. The corresponding free space through the recess provides space in which the transmission can be positioned. This results in an optimal adaptation of the geometric shape of the dirty liquid tank arrangement to the cleaning head.

In one embodiment, a device body is provided on which the cleaning head is arranged, wherein at least one of the following devices is positioned on the device body: tank means for cleaning liquid; valve means; battery means for driving the motor; holding rod means for holding and/or guiding the surface cleaning machine; filtering means for cleaning fluid; at least part of the driving motor. This results in a compact structure. In particular, elements of the surface cleaning machine which have a relatively high weight, such as for example the drive motor, can be positioned lowest in the vicinity of the cleaning head. Furthermore, for example a removable valve arrangement for supplying cleaning fluid to the cleaning head can be positioned on the device body. A valve arrangement for supplying the cleaning fluid to the cleaning head and a filter arrangement for the cleaning fluid are located on the device body, which can be protected in particular in the housing. Furthermore, the battery arrangement can be positioned optimally, especially if the drive motor itself is arranged on the machine body. It can also be provided that at least part of the drive motor is positioned in the device housing. For example, the machine body is used to "anchor" the drive motor to the surface cleaning machine.

It is advantageous if the drive motor is at least partially arranged between the device body and the cleaning head, wherein the drive motor is in particular at least partially arranged in the device body part. In this way, for example, the battery arrangement can be optimally arranged in the device housing. Furthermore, a torque transmission from the drive motor to the cleaning roller unit on the cleaning head can be realized in a simple manner. The drive motor can here (in view of the intended operation with the cleaning roller unit supported on the surface to be cleaned) be arranged relatively far below, so that ease of handling results. A pivotability between the cleaning head and the device body can also be achieved in this arrangement in a simple manner.

It is advantageous if the cleaning head is pivotable about a pivot axis relative to the drive motor and/or the device body, wherein the pivot axis is in particular oriented parallel or coaxially to the motor axis of the drive motor. This results in expanded operating options; the accessibility of spatially narrow regions of the surface to be cleaned is improved, since the device body can be repositioned in an adapted manner to the cleaning head. A corresponding pivot bearing can be designed in a simple manner by, for example, designing the housing of the drive motor as an inner sleeve and the outer sleeve arranged on the device body in such a way that the pivot bearing is realized.

In one embodiment, the cleaning roller holder on which the cleaning roller unit is positioned has an accommodation chamber with an accommodation chamber for a dirty liquid tank arrangement. In this case, the receiving chamber can be multi-chambered, and the receiving chamber can comprise a plurality of subspaces. In principle, the subspaces can here be fluidly connected to one another or can be fluidically separated from one another.

In particular, the receiving chamber is assigned a fastening device by means of which the dirty liquid tank device is fastened on the receiving chamber, wherein the fastening device is designed releasably in order to allow the dirty liquid tank device to be removed from the cleaning head , and in particular, the fastening device is designed in such a way that the dirty liquid tank device is held in a holding position on the receiving chamber by means of a positive fit. Fastening of the dirty liquid tank arrangement on the receiving chamber can thus be achieved in a simple manner. Furthermore, the dirty liquid tank arrangement can be easily removed in order to empty and, if necessary, clean it. Furthermore, the fastening device is designed in such a way that the dirty liquid tank device is positioned in a defined manner relative to the cleaning roller unit with the feed nozzle. In particular, the scraper guide can be positioned in a defined manner relative to the cleaning roller unit.

In a structurally simple embodiment, the fastening device comprises at least one pivotable flap, or is itself a flap. The receiving chamber can be easily released by means of the pivotable flap, so that the dirty liquid tank device can be inserted or removed. When the flip cover acts on the dirty liquid tank device, it can also be ensured by the flip cover that the dirty liquid tank device remains in position. Furthermore, the flap can be designed in such a way that a certain pretension is applied to it, so that the dirty liquid container device is positioned in a defined manner on the receiving chamber, so that in particular the feed nozzle of the dirty liquid container device and/or optionally The scraper-off guide is definedly positioned relative to the cleaning roller unit.

It is advantageous here if the pivot axis of the at least one flap is aligned at least approximately parallel to the axis of rotation of the cleaning roller unit. This results in a structurally simple structure. The dirty liquid tank unit can be easily removed and inserted again.

Advantageously, at least one flap acts on an upper side of the dirty liquid tank device, which faces away from the underside, wherein the underside of the dirty liquid tank device faces towards the receiving bottom of the chamber. This makes it possible to ensure in a simple manner that the dirty liquid tank arrangement remains in place on the receiving chamber. Furthermore, defined positioning can be achieved.

Advantageously, at least one flap is configured as a pressing holder, which positions the dirty liquid container device in a defined manner relative to the cleaning roller unit and/or in the receiving chamber, and in particular presses the dirty liquid container device in the holding position. against the bottom of the holding chamber. As a result, the dirty liquid tank device can be easily removed or reinserted for the operator, and the positioning can be achieved to a certain extent automatically; the operator does not have to worry about exact positioning.

For example, at least one flap is spring-loaded and/or elastically designed such that the dirty liquid tank arrangement is held in the receptacle with pretension. This prestressing ensures that the inlet mouth of the dirty liquid tank arrangement is positioned in a defined position relative to the cleaning roller unit.

In a structurally simple embodiment, at least one recess is arranged on the upper side of the dirty liquid tank device, and at least one flap has at least one counter-element for sinking into the at least one recess. Mobility of the dirty liquid tank arrangement in the removal direction on the receiving chamber can thus be prevented in particular in a simple manner.

Furthermore, it is advantageous if at least one recess has at least one undercut and at least one counterpart element has a locking element adapted to the at least one undercut, which prevents the dirty liquid tank device from being accommodated when the at least one flap is closed. Mobility in the direction in which the bottom of the chamber leaves. This makes it possible to achieve a positive fit which ensures that the dirty liquid tank arrangement is secured against falling out during the holding position. Furthermore, the positioning of the dirty liquid tank arrangement relative to the cleaning roller unit can thus be achieved in a simple manner.

In particular, the receiving chamber and the dirty liquid tank arrangement are designed to be adapted to one another in such a way that a vertical movement of the dirty liquid tank arrangement transverse to the bottom of the receiving chamber is prevented during the holding position of the dirty liquid tank on the receiving chamber. Line mobility. Fastening is thus achieved in a simple manner. Thus, the bottom prevents movement in a vertical line parallel to the bottom, and the flap prevents movement in the opposite direction.

In one embodiment, the dirty liquid tank device has one or more flaps. By opening the flap, the dirty liquid tank unit can be emptied and, if necessary, cleaned in a simple manner. In particular, the flap forms the upper side of the dirty liquid tank device, on which at least one flap of the fastening device can act.

In one embodiment, the dirty liquid tank arrangement is configured as a unit. The unit can here comprise one chamber or a plurality of chambers. The unit can here be removed as a whole from the cleaning head or can be inserted into it. In principle, it is also possible for the dirty liquid tank arrangement to have subunits that are separate from one another, which can be independently removed from the cleaning head or placed on it.

In one embodiment, the cleaning roller unit is constructed in two parts (is a two-part cleaning roller) with a first part and a second part, wherein the first part of the cleaning roller unit is assigned the first chamber of the dirty liquid tank arrangement , and the second part of the cleaning roller unit is assigned the second chamber of the dirty liquid tank device, and in particular, the drive motor acts on the intermediate region between the first part and the second part. The middle area is, for example, the middle area of the shaft. This results in a space-saving and structurally simple design for torque transmission from the drive motor to the cleaning roller unit with (exactly one) axis of rotation. In particular, this enables the drive motor to be positioned such that its motor axis is transverse to the axis of rotation of the cleaning roller unit.

Advantageously, there is provided a scraper guide for the dirty liquid, which acts on the cleaning roller unit and which is arranged on the inlet mouth of the dirty liquid tank device. Dirt can be stripped from the cleaning roller unit by means of the scraper guide, and the detached dirt can be fed into the dirty liquid tank arrangement, in particular via the feed nozzle.

In particular, the scraper guide is arranged and designed in such a way that dirt entrained by the cleaning roller unit is stripped from the cleaning roller unit by scraping off and guided towards the feed nozzle of the dirty liquid tank arrangement. The feeding of the dirty liquid at the inlet nozzle into the dirty liquid tank arrangement can also take place by the action of centrifugal force, at least in part via the impact effect. Dirty liquid can be thrown at least partially via the scraper guide at the feed nozzle into the dirty liquid tank arrangement.

It is particularly advantageous if the scraper guide is designed in such a way that the dirty liquid is guided, without suction, via the scraper guide at the feed nozzle of the dirty liquid tank device into the dirty liquid tank device. . The scraper guide is then arranged in particular directly on the feed nozzle of the dirty liquid tank device. In particular, the scraper guide then itself forms the wall of the feed nozzle. Overall, this results in a structurally simple construction of the surface cleaning machine, since it is not necessary to provide a suction machine with a blower motor, a low-voltage line and the like. Furthermore, it is not necessary to provide a separator.

It is also advantageous if the scraper guide is arranged downstream of the feed nozzle with respect to the direction of rotation of the cleaning roller unit. Dirty liquid can thus be detached from the cleaning roller unit via the scraping effect and guided into the dirty liquid tank arrangement.

It is particularly advantageous if the scraper guide protrudes into the covering of the cleaning roller unit. Dirty liquid can thus be correspondingly detached from the cleaning roller unit by scraping off.

It is advantageous if the scraper guide is rounded or chamfered at the edge protruding into the covering of the cleaning roller unit and facing the feeding nozzle. This results in protection of the covering fibers. Furthermore, the rotary drive of the cleaning roller unit is operated in an energy-efficient manner.

It is then particularly advantageous if, for a wet coating, the scraper guide protrudes into the coating to a depth of at least 5% of the thickness of the coating.

In principle it is possible for the scraper guide to be arranged on the cleaning roller holder. In an embodiment, the scraper-off guide device is arranged on the dirty liquid tank device and can be removed from the cleaning head together with the dirty liquid tank device. When the dirty liquid tank device is positioned in the holding position on the cleaning head, the scraper guide is then automatically and defined "correctly" positioned relative to the cleaning roller unit.

In particular, the scraper guide is formed by one or more edge elements, that is to say by one or more slats, which have corresponding slats which in particular can protrude into the covering of the cleaning roller unit. Edge. Preferably, the edge element at least partially forms a wall of the inlet nozzle.

It is also advantageous if sweeping elements are arranged on the cleaning head, by means of which the cleaning roller unit is fed with coarse-grained dirt for entrainment by the cleaning roller unit.

In particular, the feed nozzle of the dirty liquid tank device is positioned between the scraper guide and the cleaning element. As a result, coarse-grained dirt transported via the cleaning elements of the cleaning roller unit can be entrained by the cleaning roller unit and scraped off at the scraper guide.

It is particularly advantageous if a battery device and in particular a rechargeable electronic device are provided for supplying the drive motor with electrical energy. As a result, the surface cleaning machine can be operated independently of the grid. Easy operability is obtained.

It is also advantageous if the drive motor is arranged between the battery arrangement and the cleaning head. This results in optimum positionability of the battery arrangement.

It is also advantageous if a tank arrangement is provided for the cleaning fluid. This makes it possible to wet the surface to be cleaned directly or indirectly (by wetting the cleaning roller unit). The cleaning fluid is in particular water which can be mixed with chemical cleaning agents. The dirt on the surface to be cleaned can be wetted by the cleaning liquid in order to achieve improved detachability.

In a structurally simple embodiment, the tank arrangement for the cleaning fluid is positioned in the Clean the top of the roller unit. The feeding of cleaning fluid to the cleaning head and in particular to the cleaning roller unit then takes place exclusively under the force of gravity. No additional pumps need to be provided for conveying the cleaning fluid.

It is advantageous if the inlet mouth of the dirty liquid tank arrangement has a longitudinal extent oriented parallel to the rotational axis of the cleaning roller unit. As a result, dirty liquid can be fed into the dirty liquid tank arrangement over a large length.

The surface cleaning machine is designed in particular as a manually operated or manually guided surface cleaning machine. Due to the support on the surface to be cleaned via the cleaning roller unit, the operator can hold the surface cleaning machine at the end facing away from the cleaning head (so that it cannot tip over) and guide it over the surface to be cleaned.

In one embodiment, the cleaning head is self-moving and self-deflecting. A cleaning robot, in particular a wiping robot, can thus be realized. The cleaning roller unit is in particular a wiping roller unit with one or more wiping rollers. Such a wiping roller can then in particular perform wet cleaning of surfaces and especially hard floors. It can also realize cleaning function. Such a cleaning function can be realized, for example, via a separate cleaning roller unit and/or via a cleaning edge, wiping roller unit. Due to the self-moving and self-direction structural design of the cleaning head, automatic surface cleaning can be performed.

In particular, the surface cleaning machine comprises a cleaning head and a stationary station, the cleaning head can be moved relative to the stationary station, wherein the stationary station is provided for at least one of the following: in non-cleaning operation of the cleaning head , storing the cleaning head; charging the battery unit arranged on the cleaning head; limited discharge or partial discharge of the battery unit arranged on the cleaning head; cleaning the cleaning roller unit of the cleaning head; emptying the dirty liquid tank unit ;Fill the tank unit for cleaning fluid with cleaning fluid. The stationary station forms a docking station for the cleaning head.

It is particularly advantageous if the translational drive of the cleaning head is provided via a cleaning roller unit and/or an additional support device. The cleaning head can thus be configured in a self-propelling manner.

For the same reason, it is advantageous if the orientation of the cleaning head is provided via the cleaning roller unit and/or via an additional support device. A self-directing cleaning head, in particular for a wiping robot, can thus be realized.

In one embodiment it is provided that the rotational drive of one or more cleaning rollers of the cleaning roller unit is effected via a drive motor in clockwise and counterclockwise direction. In this way, for example, a direction reversal for the cleaning head movement can be realized. In addition, it is thereby possible to achieve changeability.

In one embodiment, the cleaning roller unit comprises at least one first cleaning roller having a first orientation of the axis of rotation and a second cleaning roller having a second orientation of the axis of rotation, wherein the first orientation and the second orientation are at angles different from 0° and 180° to each other. In particular, the cleaning rollers of the cleaning roller unit are arranged triangularly relative to one another. Traversing and reversing drives for the cleaning head can thus be realized in a simple manner. The cleaning roller (especially the wiping roller) of the cleaning roller unit is responsible for cleaning, and is responsible for constituting self-propelled and self-direction changing. The orientation can be achieved in a simple manner by means of different rotational speeds and different rotational directions on the first cleaning roller and on the second cleaning roller. In addition, good cleanability of corners, edges, joints or the like of walls is obtained.

In particular, a wedge-shaped arrangement of the first cleaning roller and the second cleaning roller on the cleaning head is provided, wherein in particular the wedge-shaped tip is located in the region of the front end of the cleaning head. A self-moving and self-deflecting realization of the cleaning head can thus be realized in a simple manner. This results in a high cleaning effect for areas close to the edges.

It is also advantageous that the rotation of the first cleaning roller and the rotation of the second cleaning roller can be driven independently of one another, wherein in particular by corresponding actuation of the first cleaning roller and of the second cleaning roller, a rotation of the cleaning head can be achieved. direction change. This results in a self-moving and self-deflecting configuration of the cleaning head in a structurally simple construction.

In one embodiment, transmission 68 includes a speed reducer. The rotational speed reducer is used to reduce the rotational speed compared to the rotational speed of the motor shaft. For example, the rotational speed of a standard electric motor is on the order of 7000 revolutions per minute. The speed reducer provides for reducing the speed to, for example, about 400 revolutions per minute.

The speed reducer may be arranged in the inner sleeve 52 on the cleaning roller holder 60 or outside the inner sleeve 52 .

The speed reducer is designed, for example, as a planetary gear.

The transmission 68 also includes a bevel gear, which provides torque reversal in order to cause a drive of the cleaning roller unit 18 with the axis of rotation 58 transverse (and in particular perpendicular) to the motor axis 46 . In particular, the bevel gear is arranged downstream of the speed reducer.

In one embodiment, the bevel gear has one or more gears, which are coupled in a rotationally fixed manner to corresponding shafts of the speed reducer. These gears act on bevel gears for angular transformation.

In one exemplary embodiment, the transmission 68 also includes a belt, which is torque-actively coupled to the bevel gear and acts on the shaft 70 . The belt bridges the gap between shaft 70 and the bevel gear and provides rotational speed reduction.

The first chamber 110 contains dirty fluid from the first portion 72 of the cleaning roller unit 18 , while the second chamber 112 contains dirty fluid from the second portion 74 of the cleaning roller unit 18 .

In principle, it is possible here that the first chamber 110 and the second chamber 112 are fluidically connected to one another, and here, for example, are fluidically connected to a common drain opening.

It can also be provided that the first chamber 110 and the second chamber 112 are separated from each other in a fluid-tight manner and that each chamber 110 , 112 has its own outlet mouth.

The first chamber 110 and the second chamber 112 are spaced apart; between the first chamber 110 and the second chamber 112 the dirty liquid tank arrangement 66 has a recess 114 . The recess 114 is arranged relative to a longitudinal extension axis 116 of the dirty liquid tank arrangement 66 in the central region of the dirty liquid tank arrangement 66 .

The axis of longitudinal extension 116 is oriented parallel to the axis of rotation 58 of the cleaning roller unit 18 when the dirty liquid tank arrangement 66 is fastened on the cleaning head 14 in the holding position 100 .

A longitudinal extension axis 116 of the dirty liquid tank arrangement 66 extends between a first outer end 118 and a second outer end 120 of the dirty liquid tank arrangement 66 , wherein the dirty liquid tank arrangement 66 extends between the first outer end 118 and the second outer end 120 . There is a maximum length dimension between the two outer ends 120 .

The recess 114 is used to guide at least a partial region of the transmission 68 . The cleaning roller unit 18 is driven centrally. Transmission 68 bridges the distance between drive motor 28 and shaft 70 . Recess 114 leaves to a certain extent the space region for receiving gear unit 68 on dirty liquid tank arrangement 86 .

It can be provided that the receiving chambers 64 each have a receiving chamber 88 for the first chamber 110 and the second chamber 112 .

It is also possible to provide a common receiving space 88 for the first chamber 110 and the second chamber 112 .

The first chamber 110 and the second chamber 112 are connected to each other via a bridging piece 122 , so that the dirty liquid tank arrangement 66 forms a unit and can be removed as a whole from the cleaning head 14 or inserted into it.

In one exemplary embodiment, the dirty liquid tank arrangement 66 has a cover plate 124 , which is pivotably mounted on the first chamber 110 and the second chamber 112 via spaced apart pivot bearings 126 a , 126 b .

The cover plate 124 can be folded up in order to provide corresponding emptying openings for the first chamber 110 and the second chamber 112 and to be able to clean the interior of the dirty liquid tank arrangement 66 if necessary.

In the embodiment shown in FIGS. 8 to 10 , the first chamber 110 and the second chamber 112 are fluid-tightly separated from each other. The cover plate 124 is a common cover plate for the first chamber 110 and the second chamber 112 . By opening the cover 124 the first chamber 110 and the second chamber 112 can then be emptied or access is provided to the first chamber 110 and the second chamber 112 in order to be able to carry out corresponding cleaning.

The cover plate can be fixed with the first chamber 110 and/or the second chamber 112 and/or the bridge piece 122 in such a way that when the cover plate 124 is closed, a fluid-tight seal is provided (except for the inlet nozzle). Dirty liquid tank unit 66.

In principle, it is possible for the dirty liquid tank arrangement 66 to also comprise mechanically separate chambers, whereby one chamber in each case is assigned to the first part 72 and the second part 74 of the cleaning roller unit 18 . In this case, the corresponding part of the dirty liquid tank arrangement must then be removed or inserted separately from the cleaning head 14 .

The dirty liquid tank arrangement 66 has an underside 128 which is formed on the outside of the bottom 84 on the first chamber 110 and the second chamber 112 respectively. Furthermore, it has an upper side 130 opposite the lower side 128 , which is formed on the outer side of the cover plate 124 .

A recess 132 (or a plurality of recesses 132 ) is formed on the upper side 130 of the dirty liquid tank arrangement 66 and thus on the cover plate 124 . The recess or recesses 132 are groove-shaped and have undercuts 134 .

The flip cover 102 has a counter element 136 (or a plurality of counter elements 136 ) which are used to cooperate with the recess 132 .

Arranged on the counter element 136 or on the counter elements 136 is a locking element 138 ( FIGS. 5 to 7 ) for cooperating with the undercut 134 . When the counter element 136 with its locking element 138 has sunk into the recess 132 and reached the holding position 100 , the locking element 138 then bears against the undercut 134 . As a result, the flap 102 is locked to prevent the upper side 130 of the dirty liquid tank arrangement 66 from swinging away. A corresponding effort must be exerted in order to guide the locking element 138 away from the undercut 134 .

The dirty liquid tank device 66 is positioned relative to the flap 102 and the receiving chamber 64 in such a way that the locking element 138 sinks into the recess 132 when the dirty liquid tank device 66 is positioned on the receiving chamber 64 in the holding position 100 , and correspondingly bears against the undercut surface 134 and thus ensures that the positioning 100 is maintained.

In an embodiment, the dirty tank assembly 66 has a step 140 that matches the step 96 (see FIG. 6 ).

When the dirty liquid tank device 66 is inserted into the receiving chamber 88 , the receiving chamber wall 86 locks the movement of the dirty liquid tank device 66 in the receiving chamber 88 in a direction transverse to the removal/insertion direction 92 .

This positive locking is optionally supported by steps 96 , 140 .

The bottom 84 of the receiving chamber 64 prevents the dirty liquid tank device 66 from being "lost" when inserted.

When the flap 102 is closed and the locking element 138 is positioned in the recess 132 against the underside 134 , a movement parallel to the removal direction 92 is then prevented in order to secure the dirty liquid tank device 66 on the receiving chamber 64 The hold position is 100.

The flap 102 is designed in particular as a press holder which provides a defined positioning of the dirty liquid tank arrangement 66 relative to the cleaning roller unit 18 .

In particular, the flap 102 is arranged or formed elastically in such a way that, in the holding position 100 , a corresponding positioning force is exerted on the flap 100 and, in particular here, the dirty liquid tank arrangement 66 is pressed against the base 84 and the wall region 94 . The pressing force against the wall region 94 is also supported by the step 96 on the wall region 94 in cooperation with the step 140 in the dirty liquid tank arrangement 66 .

It can be provided that the flap 102 is supported elastically on the pivot bearing 106 , for example. Alternatively or additionally, the flap 102 can be formed on the counterpart element 136 in such a way that a corresponding elastic force can be exerted on the dirty liquid tank arrangement 66 , for example.

The cleaning head 14 has a scraper guide 142 (see FIG. 5 ) which acts on the cleaning roller unit 18 (and here on the first part 72 and the second part 74 ) and is used to make the 18 Entrained dirty liquid (in particular water with dirt particles) escapes and is fed to the inlet 144 of the dirty liquid tank device 66 which is fastened to the cleaning head 14 in the holding position 100 . As a result, dirty liquid is then fed into the dirty liquid tank arrangement 66 .

The feed nozzle 144 of the dirty liquid tank device 66 is slot-shaped ( FIG. 9 ). It comprises a first part 146 and a second part 148 , the first part being the inlet mouth for the first chamber 110 and the second part 148 being the inlet nozzle for the second chamber 112 .

In the exemplary embodiment shown in FIG. 9 , the first part 146 and the second part 148 each have a greater length on the axis of longitudinal extension 116 than the associated chamber 110 or 112 . The dirty liquid tank device 66 has walls on the ends of the inlet nozzles 144 on the first part 146 and the second part 148 respectively, so that the dirty liquid imported through the first part 146 and the second part 148 of the inlet nozzle 144 can be respectively Delivered to the first chamber 110 or the second chamber 112.

First part 146 of feed nozzle 144 is assigned to first part 72 of cleaning roller unit 18 . The second part 148 of the feed nozzle 144 is assigned to the second part 74 of the cleaning roller unit 18 . The first part 146 and the second part 148 of the inlet mouth 144 are spaced apart from one another corresponding to the distance between the first part 72 and the second part 74 .

Preferably, the first portion 146 and the second portion 148 respectively have a respective wrap length along the axis of rotation 58 corresponding at least approximately to the first portion 72 and the second portion 74 of the cleaning roller unit 18 .

The scraper guide 142 is designed such that dirty liquid is scraped off from the cleaning roller assembly 18 via it and guided into the feed nozzle 144 .

It is possible here that, during the rotation of the cleaning roller unit 18 , a guiding effect is achieved via the action of the centrifugal force and the dirty liquid is thrown to a certain extent into the dirty liquid tank arrangement 66 .

The scraper-off guide 142 is spaced from the axis of rotation 58 .

In one embodiment (see, for example, FIG. 5 ), the scraper guide 142 protrudes to a certain depth into the covering 42 of the cleaning roller unit 18 . This depth is in particular at least 5% of the thickness D ( FIG. 5 ) of the covering 42 of the cleaning roller unit 18 , taking into account the wet state of the covering 42 .

The scraper-off guide 142 is formed in particular by one or more edge elements 150 . For example, the first part 72 and the second part 74 of the cleaning roller unit 18 are each assigned an edge element 150 .

The edge elements 150 are designed as guide strips, which protrude accordingly into the covering 42 on the first part 72 and the second part 74 of the cleaning roller unit 18 .

The edge element 150 has a relatively small thickness, which is in particular smaller than the thickness D of the covering 42 .

In one exemplary embodiment, the edge element 150 or the edge elements 150 are curved.

The scraper-off guide 142 forms in particular a wall of the inlet nozzle 144 with an edge element 150 or a plurality of edge elements 150 .

One or more edge elements 150 are rounded or chamfered at the edge facing inlet nozzle 144 . This protects the fibers of the covering 42 and requires less force to be overcome when the cleaning roller unit 18 rotates. This in turn achieves an energy-saving effect. This rounding at the edge is indicated by reference numeral 151 in FIG. 5 .

In principle it can be provided that the scraper guide 142 is arranged on the cleaning roller holder 60 .

In the exemplary embodiment shown, the scraper guide 142 is arranged on the dirty liquid tank device 66 .

The dirty liquid tank arrangement has a wall 152 which faces the wall region 94 in the holding position 100 . One or more edge elements 150 are arranged on respective walls 152 of the first chamber 110 and of the second chamber 112 .

A corresponding scraper guide 142 is preferably arranged here outside the flap 124 of the dirty liquid tank device 66 .

In this embodiment, the scraper guide 142 is removed from the cleaning head 14 when the dirty fluid tank assembly 66 is removed from the cleaning head 14 .

Furthermore, it is provided that a cover 154 is positioned on the cleaning head 14 associated with the cleaning roller unit 18 . The cover 154 is arranged directly behind the scraper guide 142 (with one or more edge elements 150 ). The edge element 150 is curved in such a way that it is adapted to a corresponding curvature of the cleaning roller unit 118 with the covering 42 .

In principle, the cover 154 touches the covering 42 or penetrates into it, wherein the depth of penetration is preferably smaller than the depth T of penetration of the scraper-off guide 142 .

In one embodiment, a fluid line 40 or a plurality of fluid lines 40 lead into a region 156 between the cover 154 and the scraper guide 142, in which region the cleaning roller unit 18 can then be loaded to Cleaning fluid from tank unit 34.

In particular, the region 146 has a length along the axis of rotation 58 at least approximately corresponding to the length of the first portion 72 or the second portion 74 of the cleaning roller unit 18, so that a uniform flow of the cleaning roller unit 18 over its length can be achieved. load.

In the exemplary embodiment shown, the cover 154 is arranged on the dirty liquid tank arrangement 66 .

Accordingly, it must be provided that a suitable connection is made to a fluid line 40 or a plurality of fluid lines 40 .

With respect to direction of rotation 158 (cf. FIG. 5 ) of cleaning roller unit 18 during cleaning operation, scraper guide 142 with its edge element 150 or a plurality of edge elements 150 thereof is arranged downstream of feed nozzle 144 . This makes it possible to “throw” dirty liquid, which was previously entrained by the cleaning roller unit 18 from the surface 16 to be cleaned and transported in the direction of the scraper guide 142 , into the feed nozzle 144 via the scraper guide 142 And thus be thrown into the dirty liquid tank device 66 .

In one embodiment, the cleaning roller unit 18 is also assigned a sweeping element 160 which is used to convey coarse dirt to the cleaning roller unit 18 . This coarse dirt can then be entrained by the cleaning roller unit 18 .

The feed nozzle 144 is arranged between the scraper guide 142 and the cleaning element 160 .

In the exemplary embodiment shown, the cleaning element 160 is arranged on the cleaning roller holder 60 at the holding area 62 . The cleaning element 160 is designed in such a way that it can act on the surface to be cleaned at least in the range of the angular positioning of the surface cleaning machine 10 with respect to the longitudinal axis 20 relative to the surface 16 to be cleaned (when the surface cleaning machine 10 is not standing steeply). The clean side 16 is used for sweeping functions.

The cleaning element 160 is, for example, arranged pivotably on the cleaning roller holder 60 and/or is designed elastically.

In particular, the cleaning element 160 protrudes into the casing 42 of the cleaning roller unit 18 . However, it may also not be in contact with the covering 42 or be spaced therefrom.

With regard to the direction of rotation 158 of the cleaning roller unit 18 , when the cleaning roller unit is driven in its rotational movement by the drive motor 28 , the surface 16 to be cleaned is followed first by the cleaning element 160 and then by the guidance of the cleaning roller holder 60 A region 162 , which is (hollow) cylindrical in its shape and is adapted to the cleaning roller unit 18 , then the feed nozzle 144 , and then the scraper-off guide 142 with one or more edge elements 150 , and then the cover 154 , wherein the region 156 is located between the cover 154 and the scraper-off guide 142 .

In the illustrated embodiment, the surface cleaner 10 is designed without a suction unit. Dirty liquid entrained by the cleaning roller unit 18 is not sucked into the dirty liquid tank arrangement 66 by an additional suction machine, but is merely scraped off the guide device 142 to provide feeding of the dirty liquid into the dirty liquid tank arrangement 66 .

In principle, however, feeding can still be supported by an additional suction machine.

The surface cleaner 10 works as follows:

During cleaning operation, dirty liquid tank arrangement 66 is fastened on cleaning head 14 in holding position 100 .

For the cleaning process, the surface cleaning machine 10 is merely positioned via the cleaning roller unit 18 on the surface 16 to be cleaned. The drive motor 28 drives the cleaning roller unit 18 in a rotational movement in a rotational direction 158 about the (single) rotational axis 58 .

The cleaning roller unit 18 is loaded with cleaning liquid from the tank arrangement 34 .

Dirt on the surface 16 to be cleaned is moistened when the moistened covering 42 of the cleaning roller unit 18 acts on the dirt and thus facilitates its detachability.

The rotation of the cleaning roller unit 18 results in a mechanical action on the dirt on the surface 16 to be cleaned in order to achieve better detachability from the surface 16 to be cleaned.

Possible coarse dirt can be conveyed to the cleaning roller unit 18 by means of the sweeping elements 160 .

Dirty liquid (dirt particles, cleaning liquid with detached dirt) is entrained by the cleaning roller unit 18 and detached from the cleaning roller unit 18 on the scraper guide 142 and (in particular under the action of centrifugal force) is It is guided into the feed nozzle 144 and from there into the dirty liquid tank arrangement 66 . The scraper guide 142 causes the dirty liquid to escape from the coating 42 of the cleaning roller unit 18 by scraping off.

In particular, the feeding of the dirty liquid into the dirty liquid tank arrangement 66 takes place without a suction machine.

Dirty fluid tank assembly 66 is removably positioned on cleaning head 14 .

Flip cover 102 provides security in retention position 100 . In the holding position 100, the feeding nozzle 144 of the dirty liquid tank device 66 is oriented relative to the cleaning roller unit 18 in relation to the scraper guide 142 in such a way that the corresponding removal and feeding functions are realized as described above. .

With its function as a pressing holder, the flap 102 provides that an edge element 150 or a plurality of edge elements 150 are pressed into the covering 42 to a depth T in order to achieve an optimal release function by scraping off.

In particular, the scraper guide 142 is arranged on the dirty liquid tank arrangement 66 and can be removed together with the dirty liquid tank arrangement from the cleaning head 14 .

The flap 102 is pushed with its counter element 136 and the locking element 138 arranged on the counter element onto the upper side 130 of the dirty liquid tank arrangement 66 and thus ensures a holding position in which a scrape-off is also achieved. The above-mentioned relative positioning of the guide device 142 with respect to the cleaning roller unit 18 .

In holding position 100 , a positive holding of dirty liquid tank arrangement 66 on receiving chamber 64 is provided.

To remove the dirty liquid tank assembly 66 ( FIGS. 3 , 6 , 7 ), the flap 102 is opened. The flip is pivoted in the direction of the device body 12 . In order for the locking element 138 to be guided out of the recess 132 with the undercut 134 , a corresponding elastic deformation of the counterpart element 136 must be carried out.

When the flap 102 is fully opened (FIG. 6), the dirty liquid tank device 66 can then be removed (see FIG. 3).

By opening the cover 124 of the dirty liquid tank device 66 , it can be emptied and, if necessary, cleaned, for example by rinsing.

The capacity of the dirty liquid tank unit 66 is, for example, about 150 ml.

The surface cleaning machine 10 has a relatively low energy requirement, since no suction machine is necessary and the dirty liquid is fed directly from the cleaning roller unit 18 into the dirty liquid tank arrangement 66 with a “minimal stroke”.

The surface cleaning machine 10 can thus be operated optimally with the rechargeable battery unit 44 .

Wet cleaning of hard floors can be carried out with a high degree of automation by means of the surface cleaning machine according to the invention. The expenditure of force during wiping is reduced or eliminated by the mechanical assistance via the driven rotary roller 18 . Wetting the cleaning roller unit 18 enables the operator to perform the cleaning process without contact with dirty liquid.

Furthermore, automatic cleaning of the cleaning roller unit 18 is achieved during the cleaning operation within a certain angle.

The dirty liquid tank device 66 is arranged between the cleaning roller unit 18 and the drive motor 28 . The direction of longitudinal extent of the feed nozzle 144 parallel to the axis of longitudinal extent 116 is parallel to the axis of rotation 58 of the cleaning roller unit 18 and transversely and in particular perpendicularly to the motor axis 46 . Furthermore, the longitudinal extension axis of the inlet mouth 144 is transverse and in particular perpendicular to the longitudinal axis 20 .

It can be provided that the drive motor 28 is also used to drive one or more suction turbines, which are correspondingly fluidically connected to the interior of the dirty liquid tank arrangement 66 in order to generate a negative pressure which improves the suction of the dirty liquid.
