Summary of the Invention

[0008] The objective of this invention is to provide a surface cleaning device of the type described at the beginning, which achieves effective cleaning results in a compact structure.

[0009] According to the present invention, in a surface cleaning device of the type described at the beginning, this task is solved in such a way that at least one side cleaning tool is coupled to at least one cleaning roller via a transmission device, and the rotation of at least one cleaning roller drives the movement of at least one side cleaning tool about a motion axis.

[0010] Effective cleaning, particularly wiping, can be achieved on surfaces to be cleaned, such as floors, through the rotational and / or oscillating motion of at least one side cleaning tool. The cleaning width can be increased beyond the length of at least one cleaning roller via the use of at least one side cleaning tool.

[0011] Rotation about the axis of motion refers here to a complete circle of at least one side cleaning tool about its associated axis of motion, without reversal of direction. Oscillation refers to the rotation of at least one side cleaning tool about its associated axis of motion in one direction and opposite directions, wherein the transition between the two directions fluctuates in time. In particular, the oscillation is periodic.

[0012] According to the invention, at least one side cleaning tool is torque-coupled to at least one cleaning roller. This allows movement about the axis of motion to be driven via the at least one cleaning roller and primarily via a drive motor. The at least one cleaning roller transmits torque to the at least one side cleaning tool. Therefore, it is unnecessary to provide an additional motor for the movement of the at least one side cleaning tool about the axis of motion. This allows for space-saving implementation of the cleaning head body.

[0013] Furthermore, the drive unit can be spatially optimized. It can be positioned next to at least one cleaning roller to achieve optimal space utilization.

[0014] More advantageously, at least one side cleaning tool is arranged next to at least one cleaning roller about an axis parallel to the axis of rotation of at least one cleaning roller, and in particular touches, overlaps with, or has a distance of at least 1 cm parallel to the axis of rotation. This results in a larger cleaning width than the length of at least one cleaning roller.

[0015] In one structurally advantageous embodiment, the rotation axis of at least one cleaning roller and the motion axis of at least one side cleaning tool are oriented laterally and, in particular, perpendicularly to each other. This results in optimized space utilization and a larger cleaning width while achieving effective cleaning results.

[0016] Advantageously, at least one of the following is provided: - The transmission device includes a speed-changing transmission mechanism; - The transmission device includes a reversing transmission mechanism, and in particular an angular transmission mechanism; - The transmission device includes a bridging transmission mechanism.

[0017] The transmission mechanism is, for example, a reduction gear mechanism, to obtain at least one side cleaning tool moving at a lower speed than the rotational speed of the rotating cleaning roller.

[0018] A motion axis that is not parallel to the rotation axis of at least one cleaning roller can be realized for at least one side cleaning tool by means of a reversing transmission mechanism, especially an angular transmission mechanism.

[0019] By using a bridging transmission mechanism, the distance between the motion axis and the rotation axis of at least one cleaning roller can be achieved. This results in a space-saving construction and arrangement of the transmission device.

[0020] The design structure is advantageous because the transmission device includes a belt drive mechanism, and the drive wheel of the belt drive mechanism is coupled to at least one cleaning roller in a rotationally inert manner. This allows for a space-saving transmission device and achieves excellent operational smoothness.

[0021] Furthermore, it is advantageous to have at least one of the following features: - The belt drive mechanism is constructed as a speed reduction transmission mechanism; - The belt drive mechanism includes a driven pulley, which is coupled to the drive pulley via a belt; - The belt drive mechanism includes a driven pulley connected to a first angular drive element in a rotationally resistant manner, wherein the first angular drive element is rotatable about a first rotation axis and coupled to a second angular drive element, which is rotatable about a second rotation axis, wherein the second rotation axis is oriented transversely to the first rotation axis, and wherein, in particular, the first rotation axis is parallel to the rotation axis of at least one cleaning roller, while the second rotation axis is parallel to or coaxial with the motion axis.

[0022] A belt drive mechanism can be implemented as a speed reduction transmission mechanism in a simple way by using the diameter difference between the driving pulley and the driven pulley.

[0023] An angular drive can also be achieved in a simple manner via a belt drive mechanism and a driven pulley, so as to provide a motion axis with a spatial orientation different from the rotation axis of at least one cleaning roller.

[0024] In a structurally advantageous embodiment, the transmission device has a first gear coupled to a belt drive mechanism and rotatable about a second rotation axis, and a second gear rotatable about a third rotation axis, wherein at least one side cleaning tool is coupled to the second gear in a rotationally resistant manner, and wherein, in particular, the second and third rotation axes are oriented parallel to each other. This allows for a simple lateral spacing between the motion axis and the rotation axis, resulting in optimized space utilization. Furthermore, an angular transmission mechanism can be implemented, in which the corresponding rotation axes (especially the first and second rotation axes) intersect each other.

[0025] Furthermore, it is advantageous to have at least one of the following features: - The first gear is positioned between the drive wheel of the belt drive mechanism and the second gear; - The first gear is or includes an angular transmission mechanism element; - Regarding the forward direction of the cleaning head, the first gear is positioned behind the second gear; - The second gear can translate relative to the cleaning head body in the height direction; - The second gear is supported by a spring device, wherein the spring force of the spring device is used to press the second gear toward the plane where the cleaning head is placed; - The second gear has a first position, which is a working position of at least one side cleaning tool, and in the first position, the second gear is coupled to the first gear, and the second gear has at least one rest position, in which the second gear is decoupled from the first gear.

[0026] This results in a space-saving arrangement of the transmission device on the cleaning head, and especially on the cartridge housing with at least one cleaning roller.

[0027] The height variability of at least one side cleaning tool can be achieved in a simple manner by means of the support of the second gear via the spring device, wherein the spring force of the spring device can achieve the working position in a simple manner.

[0028] The side cleaning tool can be positioned at rest by means of the second position of the second gear, in which torque decoupling occurs and therefore no movement about the axis of motion is performed.

[0029] More advantageously, at least one side cleaning tool is positioned on the cleaning head body in a height-translatable manner, wherein the at least one side cleaning tool has at least one working position and at least one resting position, in which the at least one side cleaning tool acts on the surface to be cleaned, and in the at least one resting position, the at least one side cleaning tool is spaced apart from the placement plane of the cleaning head. This allows for a working position with a wiping function, and, if needed, at least one resting position can be achieved, in which the at least one side cleaning tool does not act on the surface to be cleaned.

[0030] Therefore, it is advantageously configured that, in at least one resting position of at least one side cleaning tool, at least one side cleaning tool is decoupled from the transmission device and not driven in terms of its movement about the motion axis. Thus, energy-efficient operation of the surface cleaning equipment is achieved when at least one side cleaning tool is not activated.

[0031] Advantageously, a drive mechanism is provided on the cleaning head, and especially on the cleaning head body, which acts on at least one side cleaning tool to achieve a change in its height. Thus, the height positioning, and indeed the positioning on the placement plane, of at least one side cleaning tool can be set and defined in a particularly controlled manner.

[0032] In one structurally advantageous embodiment, the drive unit includes a cable traction mechanism with a cable traction motor and a traction cable. The traction cable allows for the simple lifting of at least one side cleaning tool. The interface between the removable cartridge and the cleaning head body can also be easily achieved.

[0033] Advantageously, at least one of the following is provided: - A cable traction motor and at least one side cleaning tool are mounted separately on the cleaning head body; - The cleaning head body has a first lateral side and an opposite second lateral side, wherein a cable traction motor is positioned on the cleaning head body in the region of the first lateral side, and at least one side cleaning tool is positioned on the cleaning head in the region of the second lateral side. - The traction cable is guided on the cleaning head body in a portion of the area at least approximately parallel to the axis of rotation; - The traction cable is guided in a portion of the area along the housing or housing retainer for at least one cleaning roller; - A reversing device for pulling the cable is arranged on the cleaning head body.

[0034] This resulted in a space-saving design.

[0035] In one structurally advantageous embodiment, a traction cable is connected to a drive member that is movably supported on a guide device and coupled, in particular, to a shaft for at least one side cleaning tool in a detachable manner. The height of the side cleaning tool can be easily translated via the drive member with the traction cable, through the translational nature of the shaft.

[0036] Therefore, it is advantageous to have at least one of the following features: - The shaft can rotate about the axis of motion when coupled to the driving component; - The driving component includes a gripper that can grip the shaft to achieve a high degree of variability; - The drive element includes a fork-shaped element as a gripper, which has an inlet opening for inserting and removing the shaft; - The drive component is mounted on the cleaning head body in a way that prevents it from being detached.

[0037] The coupling between the shaft and the drive can be achieved in a simple way, for example, when the housing is placed onto the cleaning head body.

[0038] In an advantageous embodiment, at least one cleaning roller is arranged on a removable cartridge from the cleaning head body, at least one side cleaning tool is arranged on the same cartridge, and a drive unit is arranged on the cleaning head body. When the cartridge is placed on the cleaning head body, coupling of at least one side cleaning tool with the drive unit is achieved for height adjustment of the at least one side cleaning tool. This provides the user with simple operability. By placing the cartridge on the cleaning head body, all necessary connections, including those with the drive unit, are automatically achieved.

[0039] In one advantageous embodiment, at least one side cleaning tool is mounted on a shaft that is rotatable about a motion axis. This allows for a simple method of obtaining movement, such as rotation, of at least one side cleaning tool about the motion axis.

[0040] Therefore, it is particularly advantageous that at least one side cleaning tool is held on the axis in a floating manner and / or via a spring mechanism and / or via a joint (such as a universal joint). Thus, even in resting position, and for example when there is also pivoting relative to the cleaning head body (e.g., via a swingable housing), simple positionability of at least one side cleaning tool is obtained.

[0041] Furthermore, it is advantageous to have a spring device arranged on the shaft, supported on the gear and housing portion, wherein the spring force of the spring device is dedicated to pressing the shaft and at least one side cleaning tool toward the placement plane of the cleaning head on the surface to be cleaned. This allows for a simple construction of a corresponding drive mechanism for high variability, since active drive is only necessary in one direction (for lifting from the placement plane). This also allows for the use, for example, of a cable traction mechanism for the drive mechanism. When no corresponding reaction force is present, the spring device ensures that at least one side cleaning tool is pressed against the placement plane and, in particular, is automatically brought into the working position in the absence of a reaction force.

[0042] The task described at the beginning is also solved according to the invention by the fact that at least one side cleaning tool is a wiping tool. This allows wiping cleaning to be performed on the surface to be cleaned over a wider cleaning area (greater than the corresponding length dimension of at least one cleaning roller).

[0043] In principle, it is possible to provide the following solutions:

[0044] A surface cleaning apparatus includes: a cleaning head having a cleaning head body; at least one cleaning roller rotatable about a rotation axis; a drive motor for the at least one cleaning roller; and at least one side cleaning tool rotatable and / or oscillating about at least one motion axis, wherein the at least one side cleaning tool is a wiping tool, and particularly a wet wiping tool.

[0045] This results in an effective cleaning effect, especially for hard surfaces. The drive can, in principle, be independent of at least one cleaning roller, or it can be carried out via at least one cleaning roller by means of a transmission device.

[0046] Advantageously, at least one side cleaning tool has a loading area for the surface to be cleaned and a retaining area for fixing, in particular fixing, to a shaft. This results in effective fixation and effective cleaning of the cleaning head.

[0047] In particular, the loading area comprises sponge material and / or textile material, and is specifically configured to be self-supporting.

[0048] More advantageously, in the working position of at least one side cleaning tool, the loading area protrudes beyond the outer side of the cleaning head body. This allows for near-edge wiping cleaning using the surface cleaning device according to the invention.

[0049] In this respect, it is also advantageous that at least one side cleaning tool has an outer side located at the loading area and spaced apart from the holding area during the working position. This prevents the holding area from coming into contact with a wall or similar object and causing damage.

[0050] In one embodiment, a bearing retainer is provided, on which a rotating bearing for at least one cleaning roller is arranged, and at least one side cleaning tool is held on the bearing retainer. This allows the at least one side cleaning tool to be positioned "close" to the at least one cleaning roller. Therefore, a wider cleaning range than the length of the at least one cleaning roller can be achieved. Furthermore, the distance between the at least one cleaning roller and the at least one side cleaning tool can be kept small or completely avoided.

[0051] In particular, a housing is arranged or formed on the bearing retainer, in which the transmission device is positioned. This protects the transmission device from the influence of dirty fluids.

[0052] More advantageously, the cleaning head body has a receiving portion for at least one cleaning roller, wherein the receiving portion is closed by a transverse wall portion toward a first lateral side of the cleaning head body, and open by an opening toward a second lateral side opposite to the first lateral side, wherein at least one side cleaning tool is positioned in the area of ​​the opening. Thus, for example, at least one cleaning roller can be positioned on and secured to the cleaning head body via a simple manner. By arranging at least one side cleaning tool in the area of ​​the opening, a space-saving construction can be achieved.

[0053] Therefore, it is particularly advantageous that at least one side cleaning tool is positioned below the cap for the opening and / or below the opening, and especially between the placement plane of the cleaning head on the surface to be cleaned and the opening. Thus, for example, at least one side cleaning tool can be positioned protruding beyond the outer contour of the cleaning head body. This results in near-edge wiping cleaning. A larger cleaning width is achieved. Furthermore, the transmission device can be positioned on the cleaning head in a space-saving manner.

[0054] In one embodiment, at least one cartridge is provided, having a retaining device on which at least one cleaning roller is held, and at least one cartridge is held removably on the cleaning head body. This provides effective operability. The cartridge, together with at least one cleaning roller, can be easily secured to and removed from the cleaning head body.

[0055] Therefore, it is particularly advantageous that at least one side cleaning tool is held on at least one housing, and in particular, at least one side cleaning tool can be removed from the cleaning head body together with the housing. This results in simple operability. The cost and space consumption of the design structure for mounting at least one side cleaning tool on the cleaning head can be kept low.

[0056] In one embodiment, a housing retainer is movably arranged on the cleaning head body, and at least one housing is held in the housing retainer in a removable manner, wherein the housing retainer is supported on the cleaning head body, in particular, via a swing bearing device, in a manner that allows it to swing about a swing axis. This swingability allows, for example, at least one cleaning roller to be lifted from the surface to be cleaned, or allows for a simple floating support of at least one cleaning roller.

[0057] Advantageously, at least one of the following is arranged on the cleaning head: - A rotatable brush roller, which is separate from at least one cleaning roller and from at least one side cleaning tool, and in particular spaced apart from at least one cleaning roller and from at least one side cleaning tool; - At least one side broom, which is separate from at least one side cleaning tool, and in particular spaced apart from at least one side cleaning tool.

[0058] Therefore, in addition to wiping, suction cleaning can also be performed, especially dry suction cleaning.

[0059] Furthermore, it is advantageous to have at least one of the following features: - At least one cleaning roller has a textile liner, and in particular a microfiber liner; - At least one cleaning roller is configured as a wet wiping roller; - At least one cleaning roller is configured as a cleaning roller for hard surfaces.

[0060] Therefore, wet cleaning can be performed on surfaces such as floors. This results in optimized cleaning, especially for hard surfaces.

[0061] Furthermore, it is advantageous to have at least one of the following features: - At least one cleaning roller is equipped with a tank device for containing dirty fluid; - At least one cleaning roller is equipped with a scraping device for scraping off dirty fluid; - At least one cleaning roller is equipped with a tank device for supplying cleaning fluid.

[0062] The tank device for dirty fluids allows the dirty fluids to be contained via a fan, and in particular, also without a fan. This results in optimized cleaning performance for wet cleaning.

[0063] The dirty fluid can be scraped off from at least one cleaning roller using a scraping device. This allows for optimized guidance and collection of the dirty fluid.

[0064] The cleaning solution can be supplied via a corresponding wetting device through a tank device. The cleaning solution can be applied directly to the surface to be cleaned and / or to at least one cleaning roller. If necessary, it can also be applied to at least one side cleaning tool.

[0065] Advantageously, a wetting device is provided for wetting at least one of the following: - At least one cleaning roller; - At least one side cleaning tool; - The surface to be cleaned.

[0066] Therefore, wet wiping cleaning can be performed on surfaces to be cleaned, such as hard floors. It has proven advantageous to load cleaning fluid (pure water, with surfactant additives if necessary) onto at least one cleaning roller via a wetting device. This keeps the amount of liquid applied to the surface to be cleaned relatively low while achieving good cleaning results. Consequently, the cleaned surface dries quickly. It is also effective for cleaning liquid-sensitive surfaces, such as wooden floors. Advantageously, the cleaning fluid is carried by a tank device on the cleaning equipment. The relatively low consumption of cleaning fluid achieved by wetting at least one cleaning roller results in a longer operating time.

[0067] For the same reason, it is advantageous if at least one cleaning tool is also loaded with cleaning fluid (especially from a tank device for cleaning fluid, such as at least one cleaning roller). Effective wet wiping cleaning can then be achieved with the aid of a side cleaning tool, and a larger cleaning width can be obtained, especially for wet wiping cleaning of hard floors.

[0068] In an advantageous embodiment, the wetting device includes a first pump for delivering cleaning fluid to at least one cleaning roller and a second pump for delivering cleaning fluid to at least one side cleaning tool. Specifically, a common reservoir for cleaning fluid is provided for both the at least one cleaning roller and the at least one side cleaning tool. Thus, it can be configured, for example, in a simple manner: either only the at least one side cleaning tool is wetted, or only the at least one cleaning roller is wetted, or both the side cleaning tool and the cleaning roller are wetted. A separate reservoir for cleaning fluid is not necessary for the at least one side cleaning tool. (For example, it would be advantageous to perform cleaning only when at least one side cleaning tool is in operation, such as when cleaning should only be performed near the edge of a wall.)

[0069] A larger cleaning width is achieved when the rotation axis of at least one cleaning roller is parallel to the plane on which the cleaning head is placed on the surface to be cleaned.

[0070] In one embodiment, the surface cleaning device is self-propelled and self-steering, and is particularly configured as a vacuuming robot, a wiping robot, or a vacuum-wiping robot. It is also possible that the surface cleaning device is configured as a manually guided device, which, for example, has a lever mechanism for guidance by a standing user on the surface to be cleaned (especially the floor). The surface cleaning device can also, in principle, be configured as a compact handheld device that is directly handheld and manually guided.

[0071] According to the present invention, a method of the type described at the beginning is provided, in which a side cleaning tool is driven by at least one cleaning roller.

[0072] According to the present invention, a method of the type described at the beginning is also provided, in which, during a cleaning operation, a side cleaning tool that rotates and / or oscillates about a motion axis acts as a wiping tool on the surface to be cleaned.

[0073] The method according to the invention can be performed on the surface cleaning equipment according to the invention.

[0074] The surface cleaning device according to the present invention can be operated using the method according to the present invention.

[0075] Other advantageous designs of the method according to the invention have been described in conjunction with the surface cleaning apparatus according to the invention. Attached Figure Description

Detailed Implementation

[0077] One embodiment of surface cleaning equipment is a self-propelled and self-steering type of floor cleaning equipment. Figures 1 to 14 In particular, this surface cleaning equipment is a vacuum-wiping robot suitable for cleaning textile and hard floors.

[0078] The surface cleaning device 10 includes a cleaning head 12, which includes a self-propelled and self-steering cleaning head body 14 (traveling body).

[0079] A (ground) station (not shown in the figure) can be provided, which is especially used for charging the battery device and, if necessary, for cleaning the cleaning head 12.

[0080] During cleaning operations, the surface cleaning device 10, with its cleaning head 12 placed on the surface 16 to be cleaned, such as the ground (see, for example, [reference needed]). Figure 12 ).

[0081] A travel drive device 18 is arranged on the cleaning head body 14. This travel drive device drives the wheels 20 ( Figure 2 In one embodiment, a first wheel 20a and a second wheel 20b are provided, which share a common wheel axis 22. The wheel 20 is driven by a travel drive 18 to rotate about the wheel axis 22.

[0082] On the cleaning head body 14, a support roller 24 is also arranged spaced apart from the wheel 20. The support roller 24 has a rotation axis. This support roller can oscillate about a steering axis perpendicular to the rotation axis. In principle, it is possible that the support roller 24 is a passive steering roller, which is not driven (and in particular, is neither driven to rotate about the corresponding rotation axis nor driven to oscillate about the steering axis). The change of direction of the cleaning head 12 is achieved by corresponding drive control of the wheels 20a and 20b by a control device located on the cleaning head body 14. The change of direction is achieved, in particular, by causing the wheels 20a and 20b to rotate at different speeds.

[0083] In an alternative embodiment, the support roller 24 is configured as an active steering roller for directional control of the cleaning head 14. This drive control is correspondingly performed via a control device.

[0084] The surface cleaning device 10 has a main travel direction 26. This main travel direction 26 is the forward direction. As the cleaning head 12 travels along the main travel direction 26, the rotation axis of the support roller 24 is oriented parallel to the wheel axis 22.

[0085] The cleaning head 12 is equipped with a placement surface 28 (see, for example, see...) Figure 12 The placement plane 28 is pre-defined by the wheel 20 and the support roller 24. In the case of a flat surface 16, when the cleaning head is placed on the surface 16 via the placement plane 28, the cleaning head 12 lies flat on the surface.

[0086] The surface cleaning device 10 includes at least one brush roller 30 for suction operation. It also includes an additional cleaning roller 32, by means of which wet wiping cleaning can be performed in particular.

[0087] During the cleaning operation of the surface cleaning device 10, the brush roller 30 and / or cleaning roller 32 are placed flat on the placement plane 28 and act on the surface 16 to be cleaned. (In principle, it is possible that during the cleaning operation, both the brush roller 30 and the cleaning roller 32 act on the surface 16 to be cleaned, or only the brush roller 30 acts on the surface 16 to be cleaned. In another embodiment, it may also be configured that only the cleaning roller 32 acts on the surface 16 to be cleaned.)

[0088] A navigation device 34 is arranged on the cleaning head body 14. The navigation device 34 is a sensor device and includes at least one sensor element. The navigation device 34 is signal-operatedly connected to a control device for controlling the movement and operation of the surface cleaning equipment 10. The navigation device 34 includes, for example, one or more optical sensors, one or more wheel sensors, one or more IR sensors, and / or one or more ultrasonic sensors.

[0089] The cleaning head body 14 has a front end 36 and a rear end 38 relative to the main travel direction 26 (forward direction 26). The cleaning head 12 is equipped with a longitudinal axis 40, which extends between the front end 36 and the rear end 38 and is parallel to the main travel direction 26.

[0090] In the region of the rear end 38, in particular, a tank device 42 for dirty fluid and a tank device 44 for cleaning fluid are positioned (see, for example, see...). Figure 1 ).

[0091] In one embodiment, canister 42 and canister 44 are integrated together in a combined manner and can be removed from or inserted into the cleaning head 12 as a combination.

[0092] Here, "dirty fluid" is understood as a fluid that is, in principle, capable of flowing. It can consist of dirt particles, or it can be a mixture of dirt particles and liquid (especially water, with surfactant detergent additives if necessary).

[0093] The cleaning head body 14 has a lower side 46 facing the placement plane 28. The cleaning head body has an upper side 48 opposite to the lower side 46. The wheel 20 and the support roller 24 are arranged on the lower side 46. The navigation device 34 is positioned on the upper side 48 at least in a partial area.

[0094] On the cleaning head body 14, a bumper 50 is arranged in the area of ​​the front end 36, which allows for tactile detection of collisions between the surface cleaning device 10 and obstacles. The bumper 50 is or includes one or more tactile sensor elements that are signal-activated to the control device.

[0095] A cliff sensor 52 is arranged on the lower side 46 of the cleaning head body 14 (see Figure 3 These cliff sensors are connected to the control unit via signals. These cliff sensors 52 are used to prevent surface cleaning equipment 10 from falling, for example, in areas with stairs, by correspondingly identifying a "cliff".

[0096] The cleaning head body 14 includes a rear region 54. Tank devices 42 and 44 and a cleaning roller 32 are positioned in the rear region 54. A rear end portion 38 is located in the rear region 54. The cleaning head body 14 also includes a front region 56 connected to the rear region 54. A front end portion 36 is located in the front region 56.

[0097] In the front area 56, adjacent to the rear area 54, there is a receiving part 58 for a sludge collection container (in Figure 1 (As shown in the diagram). The sludge collection container in the receiving section 58 is specifically used to collect dry dirt and is associated with the brush roller 30.

[0098] An interface is provided at the receiving section 58, through which the corresponding sludge collection container is connected to the blower unit. The blower unit is located at the front area 56. The blower unit generates a suction flow. This suction flow is applied to the receiving area 64 where the brush roller 30 is located (see...). Figure 3 The brush roller 30 is supported in a manner that allows it to rotate about the axis of rotation 66. A drive motor is arranged in the front region 56, which drives the brush roller 30 to rotate about the axis of rotation 66 during cleaning operation.

[0099] The fan device loads the receiving area 64 with a suction flow, and in particular sucks in dry dirt and holds it in the sludge collection container (not shown) in the receiving section 58.

[0100] The sludge collection container can be removed from the receiving section 58 for emptying and cleaning.

[0101] In one embodiment, the receiving portion 58 is positioned on the cleaning head body 14 (relative to the longitudinal axis 40) between the receiving area 64 having the brush roller 30 and the can assembly 42 or 44. The receiving portion 58 is positioned on the cleaning head body 14 between the cleaning roller 32 and the brush roller 30.

[0102] Along the longitudinal axis 40, following the receiving area 64 with the brush roller 30, a rechargeable battery device 70 is installed in the front area 56 of the cleaning head body 14.

[0103] In the illustrated embodiment, the receiving area 64 with brush roller 30 is positioned relative to the longitudinal axis 40 between the battery device 70 and the receiving portion 58 for the sludge collection container.

[0104] In the region of the front end 36, a contact element 72 is arranged at the lower side 56 of the cleaning head body 14 (see...). Figure 3 These contact elements, in conjunction with the station (ground station), enable the recharging of the battery device 70.

[0105] The rotation axis 66 of the brush roller 30 is oriented transversely to and especially perpendicular to the longitudinal axis 40.

[0106] The axis of rotation 66 is oriented parallel to the placement plane 28.

[0107] In particular, the receiving area 64 with brush roller 30 is positioned between the first roller 20a and the second roller 20b (see...). Figure 3 ).

[0108] Side brooms 74a and 74b are also installed at the front end 56 of the cleaning head 12. These side brooms protrude from the periphery of the cleaning head body 14.

[0109] In one embodiment, a first side broom 74a and a second side broom 74b are provided. Each of the side brooms 74a and 74b is equipped with a drive motor in the front region 56 of the cleaning head body 14. The side brooms 74a and 74b are rotatable about rotation axes that are transverse to, and in particular perpendicular to, the placement plane 28, or form a small acute angle with the placement plane 28, particularly an acute angle less than 10°.

[0110] In one embodiment, the battery unit 70 is positioned between the drive motors for the side brooms 74a, 74b, and in particular, the battery unit 70 and these drive motors are aligned in a line perpendicular to the longitudinal axis 40. This line is, in particular, parallel to the axis of rotation 66.

[0111] In one embodiment, the blower assembly is located on one side of the cleaning head body 14, while a drive motor, for example, for the brush roller 30, is located on the other side. In particular, between the blower assembly and the drive motor is the intermediate plane of the cleaning head body 14, on which the longitudinal axis 40 lies, and which is perpendicular to the placement plane 28.

[0112] In one embodiment, a blower is located on one side of the housing 58, wherein the connection for fluid action on the sludge collection container is established via the blower through this side of the housing 58, while a drive motor is located on the opposite side of the housing 58.

[0113] On the cleaning head body 14, an openable and, in particular, flip-up cover 78 is provided at the upper side 48 (see...). Figure 1 The cover 78 covers the tank devices 42 and 44 at the upper side 48. Furthermore, the cover also covers the receiving portion 58 for the sludge collection container. The cover 78 must be opened in order to remove the sludge collection container from the receiving portion 58.

[0114] The cleaning head body 14 has a first lateral side 80 and an opposite second lateral side 82. The first lateral side 80 and the second lateral side 82 are particularly mirror-symmetrical with respect to the intermediate plane in which the longitudinal axis 40 is located.

[0115] The first lateral side 80 and the second lateral side 82 can be flat or arched.

[0116] On the cleaning head body 14, a receiving portion 84 for the cleaning roller 32 is arranged between the first lateral side 80 and the second lateral side 82. The receiving portion 84 is in particular a receiving channel. The receiving portion 84 is open toward the lower side 46 and thus toward the placement plane 28, so that the cleaning roller 32 positioned in the receiving portion 84 can act on the surface 16 to be cleaned.

[0117] The receiving portion 84 is located in the rear region 54 of the cleaning head body 14. The receiving portion is spaced apart from the rear end portion 38 of the cleaning head body 14.

[0118] The receiving portion 84 is closed at the first lateral side 80 by a transverse wall portion 86. The transverse wall portion 86 is fixedly arranged on the cleaning head body 14, or is a fixed component of the cleaning head body 14.

[0119] At the second lateral side 82, the receiving part 84 is opened via the opening 88. Figure 4 , Figure 5 A cover 90 is provided for opening 88, which can close opening 88 at the second lateral side 82.

[0120] exist Figure 1 , Figure 2 , Figure 3 and Figure 6 The image shows the cleaning head 12 and the closed cap 90. Figure 4 and Figure 5 In the middle, the cover 90 has been removed.

[0121] To position the cleaning roller 32 within the receiving portion 84, a housing 92 is provided (see [reference]). Figures 7 to 10 The housing 92 includes a retaining device 94 for the cleaning roller 32. When the housing 92 is positioned as intended in the receiving portion 84 of the cleaning head 12, the cleaning roller 32 is driven at the retaining device 94 and can rotate about the rotation axis 96.

[0122] The axis of rotation 96 is parallel to the placement plane 28. This axis of rotation is transverse to, and in particular perpendicular to, the main travel direction 26 (forward direction 26). This axis of rotation is transverse to, and in particular perpendicular to, the longitudinal axis 40. This axis of rotation is at least approximately parallel to the axis of rotation 66 of the brush roller 30.

[0123] On the cleaning head body 14, a cartridge retainer 98 is positioned in the receiving portion 84 to hold the cartridge 92, and thus indirectly to hold the cleaning roller 32 in the receiving portion 84. The cartridge retainer 98 is a non-removable component of the cleaning head 12. It may be fixedly positioned on the cleaning head 12 (on the cleaning head body 14), or in one embodiment, it may be positioned on the cleaning head body 14 in a movable manner, and in particular in a swingable manner.

[0124] A guide device 100 is provided for guiding the case 92 on the case holder 98 and holding the case in a position in the receiving part 84.

[0125] The guide device 100 includes a first portion 102 and a second portion 104, the first portion being disposed on or formed on the housing retainer 98, and the second portion being disposed on or formed on the housing 92. The first portion 102 and the second portion 104 cooperate with each other.

[0126] The retaining device 94 (cassette 92) has a circumferential wall portion 106. The circumferential wall portion 106 extends along the axial direction 108 between a first end portion 110 and an opposite second end portion 112. When the cassette 92 is positioned in the receiving portion 84 as intended, the rotation axis 96 is parallel to the rotation axis 96 of the cleaning roller 32.

[0127] Axis 108 is the axial axis. The cleaning roller 32 has a cylindrical external shape, with its axial axis parallel to the rotation axis 96. Thus, the housing 92 can be assigned circumferential and radial directions. The circumferential, radial, and axial axes 108 define polar coordinates.

[0128] The circumferential wall portion 106 has a first region 118 and a second region 120.

[0129] The second region 120 is arranged on the first region 118 in a movable manner.

[0130] The first region 118 extends circumferentially from the lower side of the circumferential wall 106 toward the placement plane 28 to the end region. Here, when the housing 92 is installed on the cleaning head 12 as specified, this end region is located in the upper region of the housing 92. In the upper region, the circumferential wall 106 has a maximum distance from the placement plane 28 about the height axis 128 perpendicular to the placement plane 28.

[0131] The first circumferential extension of the first region 118 between the end side region and the lower side is an angular range of less than 180°, and especially less than 150°.

[0132] Thus, the cleaning roller 32 can be positioned "unclamped" on the first region 118.

[0133] In one embodiment, the circumferential wall portion 106 is closed at the first region 118, that is, it is continuously formed without openings or similar structures.

[0134] The circumferential wall portion 106 has an inner side facing the cleaning roller 32 and an outer side away from the cleaning roller 32.

[0135] The second part 104 of the guide device 100 is mounted on the outer side.

[0136] In particular, the second part 104 of the guiding device 100 is configured as a guiding element in the form of a guide block, and the first part 102 is a mating element therewith. The mating of the second part 104 and the first part 102 is configured such that the guiding direction of the guide device 100 on the housing 92 in the housing holder 98 is parallel to the axis 108, or in other words, parallel to the axis of rotation 96. Retention of the direction transverse to the axis 108, or in other words, transverse to the axis of rotation 96 of the cleaning roller 32, is achieved through corresponding side recesses.

[0137] In one embodiment, an interface 138 of a wetting device 140 is arranged in a first region 118 of the circumferential wall portion 106 and in a region of the second end portion 112. The wetting device 140 allows cleaning fluid from the tank device 44 to be applied directly and, in particular, indirectly, via the cleaning roller 32 to the surface 16 to be cleaned. In an advantageous embodiment, during operation of the surface cleaning device 10, the cleaning fluid is distributed onto the cleaning roller 32 via a nozzle device disposed at the circumferential wall portion 106 and therein at the first region 118.

[0138] In one embodiment, the wetting device 140 includes a first pump 142. The first pump 142 is disposed at the cleaning head body 16, and particularly at the rear region 54. The first pump is fluidly connected via its suction side to the tank device 44 and via its pressure side to a nozzle device for loading cleaning fluid onto the cleaning roller 32. (When the housing 92 is mounted on the cleaning head 12) The first pump is coupled via its pressure side to the interface 138.

[0139] The fluid action connection with the portion of the wetting device 140 positioned outside the housing 92 on the cleaning head 14 is achieved via interface 138.

[0140] The second region 120 is configured as a flap 144, which is movably supported at the first region 118 of the circumferential wall portion 106 via a swing bearing device 146.

[0141] The swing axis 148 of the swing bearing assembly 146 is oriented parallel to axis 108, and thus also parallel to the rotation axis 96.

[0142] In one embodiment, the oscillating bearing assembly 156 includes a plurality of spaced-apart oscillating bearings 150 oriented in alignment along an oscillating axis 148.

[0143] In the illustrated embodiment (see Figure 7 It is equipped with three oscillating bearings 150.

[0144] In one embodiment, the oscillating bearing 150 includes a shaft element disposed in a first region 118, and receptacles for the shaft element disposed in a second region 120 and, for example, integrally formed.

[0145] The second region 120 is configured as a flap 144. A spring device is provided for the swing bearing device 146, wherein the spring force of the spring device is used to press the flap 144 against the cleaning roller 32, thereby clamping the cleaning roller onto the holding device 94.

[0146] The flip cover 144 (second region 120) has a closed position in which the flip cover 144 clamps the cleaning roller 32 onto the housing 92. The spring device has a clamping force perpendicular to the axis of rotation 96 (perpendicular to axis 108) for clamping retention.

[0147] In the open position of the flip cover 144, which can be achieved by overcoming the spring force of the spring device 156, especially by manual operation by the user (when the housing 92 is removed from the cleaning head 12), the cleaning roller 32 can be removed from the housing 92.

[0148] A scraping device 166 for cleaning roller 32 is arranged on the flip cover.

[0149] The cleaning roller 32 is specifically configured as a wiping roller or a wet cleaning roller. It has a sleeve 168, which has an open internal space. A lining 172, made of textile material, such as microfiber material, is mounted on the sleeve 168. During the cleaning operation of the surface cleaning device 10, the lining 172 is wetted with a cleaning liquid (clean water or clean water with surfactant additives) by a wetting device 140. By acting on the surface 16 to be cleaned, dirt can be dissolved and carried away with the lining 172 of the cleaning roller 32.

[0150] In principle, it is also possible that the cleaning roller 32 is a brush roller and is provided with bristle bundles accordingly, or that the cleaning roller 32 has a mixed lining with a textile area and a bristle area.

[0151] When the surface cleaning device 10 is in operation and the flip cover 144 is in the closed position, the scraping device 166 is pressed against the cleaning roller 32 and here pressed against the lining 172 of the cleaning roller 32.

[0152] The scraping device 166 is arranged and configured such that the dirty fluid is stripped from the lining 172 of the cleaning roller 32 and guided to the inlet device 174. The scraping device 166 has both the function of stripping and guiding the dirty fluid.

[0153] Both the scraping device 166 and the swivel device 174 are mounted on the flip cover 144. The scraping device 166 here includes at least one scraping strip 176 (see...). Figure 12 When the surface cleaning device 10 is operating and the flip cover 144 is in the closed position (and the housing 92 is positioned on the cleaning head 12 as specified), the scraping bar penetrates into the lining 172 of the cleaning roller 32. The penetrating scraping bar 176 allows the dirty fluid to be stripped from the lining 172 and guided away.

[0154] The scraping strip extends almost along the entire length of the cleaning roller 32 (with the direction of the rotation axis 96 as the length axis).

[0155] The scraping strip 176 is arranged and configured to lead to the inlet device 174 in a funnel shape.

[0156] By means of the spring force of the spring device 156, the flap 144 is pressed against the lining surface 172 of the cleaning roller 32, and the scraping strip 176 is pressed into the lining surface 172 to achieve penetration. This provides a spring-loaded scraping device 176.

[0157] Thus, for example, manufacturing tolerances in the cleaning roller or wear on the cleaning roller 32 can be compensated, because the spring-loaded oscillating bearing device 146 enables the scraping bar 176 to be automatically and correctly positioned on the cleaning roller 32 in the functions of dirt removal and dirt removal.

[0158] When the housing 92 is positioned on the cleaning head 12 as specified, the inlet device 174 (with the flap 144 in the closed position) is positioned to allow the dirty fluid to be directly introduced into the tank device 42 for the dirty fluid. In particular, the transport of the dirty fluid from the cleaning roller 32 to the tank device 42 is achieved without a blower through direct coupling of the dirty fluid from the housing 92, and in this case, from the inlet device 174 on the flap 144 of the housing 92 to the tank device 42.

[0159] The receiving section 84, the casing 92, and the canister device 42 and their structural components are designed to automatically couple the port device 174 of the casing 92 with the fluid action of the canister device 42 when the casing 92 is correctly placed into the receiving section 84, so that the canister device 42 is filled with dirty fluid.

[0160] On the retaining device 94 (of the housing 92), an edge flange 180 is arranged on the end side of the second end portion 112. This edge flange 180 forms a contact surface for the cleaning roller 32 about the axial axis 108. When the cleaning roller 180 is in contact with the circumferential wall portion 106, the edge flange 180 prevents the cleaning roller from falling off the housing 92 in the direction 108.

[0161] The housing 92 (retaining device 94) has a rotating bearing 182 at the first end 110. The cleaning roller 32 can be inserted into the rotating bearing 182 in a manner that resists relative rotation for rotation about the axis of rotation 96. The rotating bearing 192 is a fixed component of the housing 92 and is located away from the edge flange 180.

[0162] To secure the cleaning roller to the housing 92, the cleaning roller 32 is first inserted into the rotating bearing 182 with the flap 144 open, and then pressed against the circumferential wall 106, specifically against a first region 118 of the circumferential wall 106. This pushes the cleaning roller past the edge flange 180, which provides an axial contact surface. The flap 144 is then closed, i.e., placed in the closed position (see, for example, [reference needed]). Figure 7 Thus, the cleaning roller 32 is fixed to the housing 92. The housing 92 can then be pushed into the receiving portion 84. With the cover 90 open, the housing is placed onto the housing holder 98 and pushed into the receiving portion 84 in the insertion direction 184 until it is fixed about the axial axis 108. This will be described in detail below. This insertion is performed at or via the second lateral side 82.

[0163] The insertion direction 184 is at least approximately parallel to the axis of rotation 96.

[0164] The assembly of the housing 92 and the cleaning roller 32 fixed thereon is placed into the receiving part 84.

[0165] To remove the housing 92 with the cleaning roller 32, the cover 90 is opened and the axial fixation is subsequently released.

[0166] In particular, when the axial fixation is released, the housing 92 and the cleaning roller 32 are fed together, causing them to protrude from the second lateral side 82. The housing 92 with the cleaning roller 32 can then be completely removed.

[0167] Take out direction 186 ( Figure 4) is the opposite direction of insertion direction 184, and is antiparallel to that insertion direction.

[0168] The removal is carried out at the opening 88, away from the transverse wall 86.

[0169] Then, the cleaning roller 32 can be removed from the housing 92 and cleaned, for example, in a washing machine.

[0170] Regarding the construction of the housing 92 with the flip cover 144, refer to the unpublished German patent application No. 10 2024103 709.1 dated February 9, 2024.

[0171] As the housing 92 with cleaning roller 32 is inserted along the insertion direction 184 until it is axially fixed, the interface 138 on the housing is automatically connected to the rest of the wetting device 140 on the cleaning head 12 through fluid action. The cleaning roller 32 is automatically coupled to the drive device through torque action. Automatic orientation is achieved by coupling the port device 174 to the fluid action of the tank device 42 for dirty fluid.

[0172] When the housing 92 with the cleaning roller 32 is removed and the axial fixation is released accordingly, the following are achieved: automatic decoupling of the interface 138 from the rest of the wetting device 140, removal of the cleaning roller 32 from the torque transmission device, and automatic release of the fluid coupling between the port device 174 and the tank device 42.

[0173] The housing 92 has a support side 188 with a rotating bearing 182 at its first end 110. Oppositely, it has a support drive side 190. An edge flange 180 is located on the support drive side 190. The support drive side 190 enables torque coupling between the cleaning roller 32 and the drive motor for rotation about the rotation axis 96.

[0174] The edge flange 180 and the circumferential wall portion 106 are designed so that even when the flip cover 144 is in the closed position, the cleaning roller 32 on the housing 92 can be driven to rotate about the rotation axis 96.

[0175] In one embodiment, the interface 138 is located at or near the edge flange 180. A securing device 192 is provided to axially secure the housing 92 within the receiving portion 84, causing the housing 92 to be secured within the receiving portion 84 with respect to the insertion direction 184 and the removal direction 186. The guiding device 100 causes fixation in all directions transverse to it.

[0176] Regarding the construction scheme of the fixing device 192, refer to the unpublished German patent application No. 10 2024 103698.2 dated February 9, 2024.

[0177] The retaining device 192 here has a first portion disposed outside the housing 92 and associated with the transverse wall portion 86. The first portion of the retaining device 192 is fixedly disposed on the cleaning head body 14 such that it cannot be removed from the cleaning head body 14. In embodiments, particularly those with a movable housing retainer, the first portion 194 itself may be movable, or it may be positioned as a whole in a non-movable manner on the cleaning head body 14.

[0178] In the illustrated embodiment, the first portion of the fixing device 192 is arranged on the housing retainer 98.

[0179] In an alternative embodiment, particularly when the housing retainer 98 is fixedly (in a non-movable manner) on the cleaning head body 14, the first part of the fixing device 192 may also be arranged directly at the transverse wall portion 86 and positioned inside toward the receiving portion 84.

[0180] The second part of the fixing device 192, corresponding to the first part, is arranged on the housing 92.

[0181] In one embodiment, the second part of the fixing device 192 includes a nose, and in particular a plurality of noses, which are disposed on the edge flange 180 and extend outwardly in particular away from the edge flange 180.

[0182] Surface cleaning device 10 includes drive motor 200 (see...) Figure 6 It is used to drive the cleaning roller 32 to rotate around the rotation axis 96 in a rotary manner.

[0183] In one embodiment (not shown), the drive motor 200 is arranged on the cleaning head body 14, and particularly in the front region 56. Torque transmission from the drive motor 200 to the cleaning roller 32 is achieved via a transmission mechanism, which includes, for example, a belt drive mechanism, and particularly a reduction gear mechanism. With the housing 92 fixed to the cleaning head 12, torque coupling is achieved at the support drive side 190 via respective drive end bearing elements, to which the cleaning roller 32 is fitted with its sleeve 168 in a way that resists relative rotation.

[0184] In the illustrated embodiment, the drive motor 200 is a built-in motor relative to the cleaning roller 32. The drive motor 200 is a fixed component of the cleaning head 12 and is located in the rear region 54.

[0185] There is a connection to the control device via a control line, and there is an electrical connection to the battery device 70.

[0186] In particular, when the housing retainer 98 is movable (as will be described in detail below), the drive motor 200 is fixedly connected to the housing retainer 98 and can move together with the housing retainer.

[0187] When the housing retainer 98 cannot move, the drive motor 200 is arranged, for example, at the transverse wall 86, and is connected to the transverse wall directly or indirectly.

[0188] The drive motor 200 is positioned in the housing 84 and extends in a specific area about a longitudinal axis parallel to the rotation axis 96.

[0189] A motor drive component 202 is provided, which is positioned within the internal space 170 of the sleeve 168 when the cleaning roller 32 is fitted onto the drive motor 200. The motor drive component 202 is coupled to the cleaning roller 32 in a way that resists relative rotation.

[0190] The housing 92 is axially fixed to the cleaning head body 14 away from the second lateral side 82 via the fixing device 192. Thus, space is not required, particularly above the opening 88, for the fixing device between the housing 92 and the cleaning head body 14. This space can then be used, for example, for the can 44, or the cleaning head 12 can be implemented at a smaller height parallel to the height axis 128.

[0191] In one embodiment, the retaining device 192 is configured as a push-to-release latch (“push-to-release contact latch”). A “push-to-release” mechanism is provided by a push-to-release latch (also referred to as a “push-to-release latch”) positioned in the region of the transverse wall portion 86. Axial fixation can be achieved, and axial fixation can be released (for removal of the housing 92 from the receiving portion 84) by applying pressure to the housing 92, wherein the pressure application is performed along a pressure application direction at least approximately parallel to the insertion direction 184. Furthermore, pressure application can also be performed on the housing 92 in the region of the opening 88, that is, at a “larger” distance from the retaining device 192.

[0192] In this regard, see DE 10 2024 103 698.2 dated February 9, 2024.

[0193] The fixing area of ​​the housing 92 relative to the cleaning head 14 (about axis 108) is specifically located at the end of the end side of the receiving portion 84, and is located in the receiving portion 84 or in the extension line of the receiving portion 84 in front of the transverse wall portion 86. Thus, the space already existing in the receiving portion 84 is optimized for positioning the fixing device 192.

[0194] Press-fit fasteners are known in themselves and are used, for example, in furniture manufacturing.

[0195] It is possible to configure a spring device on the housing 210, which provides feed when the housing 92 is disconnected and "pops out" the housing to a certain extent.

[0196] The push-button latching device 208 can be constructed in a relatively small size along a direction parallel to the axis 108, so that it can be positioned at the end of the receiving portion 84 as described.

[0197] The feed rate generated by the press-type latching device is at least 0.5 mm, and preferably at least 1 mm. A larger feed rate is more advantageous.

[0198] The cover 90 is used to close the receiving portion 84 at the opening 88. The cover 90 also serves to prevent the housing 92 from accidentally becoming detached. For example, there is a possibility, in principle, that in the "push-release" mechanism of a push-button latching device, an object impacting the area of ​​the opening 88 could generate pressure on the housing 92 in the direction of the transverse wall 86, thereby causing the housing 92 to become detached. With the cover 90 closed, this risk does not exist.

[0199] In one embodiment, the cover 90 is fixedly (to prevent loss) connected to the cleaning head body 14. A corresponding hinge with a swing axis is provided for this purpose. In one embodiment, the swing axis is oriented transversely to, and in particular perpendicularly to, the placement plane 28. The swing axis is oriented transversely to, and in particular perpendicularly to, the insertion device 184 or the removal direction 186. The swing axis is oriented transversely to, and in particular perpendicularly to, the rotation axis 96. The swing axis is oriented transversely to, and in particular perpendicularly to, the main travel direction 26.

[0200] In particular, the cover is arranged laterally via the hinge and, for example, on the same side of the housing retainer 98 located on the cleaning head body 14.

[0201] When the cover 90 is opened, the cover 90 pivots from the rear end 38 to the front end 36 (not shown in the figure).

[0202] The hinge is, for example, spring-loaded to achieve a good closure of the opening 88 at the second lateral side 82.

[0203] In particular, when the cover 90 is closed, the cover 90 is spaced apart from the housing 92 and the second end 112, so that no pressure (which could trigger the "push-release" mechanism of the fixing device 192) is applied to the housing 92.

[0204] In order to secure the cartridge 92 (together with the cleaning roller 32) in the receiving portion 84, the cartridge 92 is pushed into the receiving portion 94 in the insertion direction 184 when the cover 90 is opened. The cartridge 92 is oriented such that the first portion 102 and the second portion 104 of the guide device 100 are nested into each other.

[0205] The housing 92 is pushed along the insertion direction 184 until the first and second parts of the fixing device 192 (press-type snap-fit ​​device) correspond to each other and achieve axial fixation.

[0206] This can be indicated, for example, by a clicking sound.

[0207] To remove the housing 92, starting from the closed position of the cover 90, open the cover 90. Then, in the area of ​​the opening 88, press the housing 92 with a pressure direction at least approximately parallel to the insertion direction 184. This causes the fixation on the retaining device 192 to be released, and the connection between the first and second parts to be severed. The housing 92 is then detached from the cleaning head body 14. In the illustrated embodiment, the housing 92 is detached from the housing retainer 98 about the axial direction 108.

[0208] In one embodiment, the fixing device 192 is also configured to provide feed to the housing 92 in a direction parallel to the removal direction 186 when the fixing is released.

[0209] As an alternative to the swingable cap 90, it is also possible to provide a cap that can be completely removed from the cleaning head body 14. In particular, the cap is held on the cleaning head body 14 by a pin element on the cap or on the cleaning head body 14.

[0210] In another embodiment, the cover is fixedly disposed on the housing 92.

[0211] A receiving wall 228 is provided on the cleaning head body 14, through which a receiving portion 84 is formed. In principle, it is possible that the housing retainer 98 is formed via the receiving wall 228, and in particular, the first part of the guide device 100 is arranged on or formed by the receiving wall 228.

[0212] In one embodiment, the housing retainer 98 is separate from the receiving wall portion 228 and is positioned movable within the receiving portion 84.

[0213] In this regard, reference is made to the unpublished German patent application No. 10 2024 103 726.1 dated February 9, 2024.

[0214] A swing bearing device 230 is provided, which allows the housing retainer 98 to be supported on the cleaning head 14 in a swingable manner. Figure 10 (As pointed out in the text).

[0215] Oscillating axis 232 (see Figure 10 This axis is parallel to axis 108, or rather, parallel to axis of rotation 96. The swing axis is transverse to, and in particular perpendicular to, the insertion direction 184 or the removal direction 186. The swing axis is transverse to, and in particular perpendicular to, the main direction of travel 26.

[0216] The swing axis 232 is parallel to the placement plane 28.

[0217] The housing retainer 98 has a wall portion 234 (see Figure 10 The first part 102 of the guide device 100 is formed on the inner side of the wall 234.

[0218] A transverse region is provided on the wall portion 234. This transverse region holds the first part of the fixing device 192. This transverse region also holds the drive motor 200 via a corresponding retainer.

[0219] Spacing tabs 242 are arranged on the outer side 240 of the wall portion 234. These tabs extend outward from the wall portion 234 and extend away from the receiving portion 84.

[0220] In one embodiment, these tabs 242 are configured in an arc shape. These tabs 242 form a swing bearing assembly 230, and therein form the portion that is mounted on the housing retainer 98. This portion mates with another portion mounted on the cleaning head body 14.

[0221] The receiving wall portion 228 has an opening that mates with the tab 242. The tab 242 (or the tab assembly in the case of an arc shape) passes through its respective opening. Thus, the mating member relative to the tab 242 (by means of which the swing bearing device 230 is formed) is fixedly positioned on the cleaning head body 14 outside the receiving portion 84, as described above.

[0222] Thus, the receiving portion 84 is positioned between the oscillating bearing assembly 230 and the rear end portion 38 of the cleaning head 12. When the housing 92, along with the cleaning roller 32, is mounted on the cleaning head 12, the housing is positioned between the oscillating bearing assembly 230 and the can assembly 42.

[0223] The fitting of the oscillating bearing device 230 is particularly mounted on the front region 56 of the cleaning head body 14.

[0224] In the illustrated embodiment, two mating parts are provided for mating with two tabs or tab assemblies 242.

[0225] The oscillating bearing assembly 230 is equipped with a spring device. In particular, each oscillating bearing of the oscillating bearing assembly 230, which consists of a mating body and an associated tab or tab assembly 242, is equipped with (at least one) spring, such as a helical spring.

[0226] The spring mechanism is arranged and configured to apply a spring force that presses the housing retainer 98 against the placement plane 28.

[0227] In principle, the force applied to the cleaning roller 32 against the surface 16 to be cleaned during cleaning operation, especially on the ground, is predetermined by the gravity of the cleaning head 12. An additional force provided by the spring mechanism can be used to press the cleaning roller 32 against the surface 16 to be cleaned via a movable housing retainer 98 having a swing bearing assembly 230 and a spring assembly. This results in improved cleaning performance.

[0228] In one embodiment, the additional force is set to be in the range of 7N to 17N.

[0229] The cleaning roller 32 can be moved via the housing retainer 98 and is supported by a spring, which also enables it to float on the cleaning head 12. This makes it possible for the cleaning roller 32 (by movement of the housing retainer 98) to avoid obstacles by briefly lifting (raising upward) the cleaning roller 32 (via the housing retainer 98) off the surface 16.

[0230] The spring force of the spring device causes the lifting action to be maintained briefly during this lifting, and once the obstacle is removed, the housing retainer 98 will move toward the placement plane 28 and press the cleaning roller 32 onto the surface to be cleaned.

[0231] In principle, it is possible to match the spring mechanism to the application. The spring force should not be too large to prevent the cleaning head body 14 from lifting, that is, the placement plane 28 must be maintained. For example, in principle, it is possible that a smaller spring force is sufficient for a floating support, rather than expecting a stronger press of the cleaning roller 32 onto the surface 16 to be cleaned.

[0232] The placement plane 28 is pre-defined by the wheel 20 and the support roller 24. The brush roller 30 is located on the placement plane 28. When the housing retainer 98 cannot move, the cleaning roller 32 is also located on the placement plane 28.

[0233] In the solution according to the invention, which has a movable cartridge holder 98, the cleaning roller 32 is, in principle, only located on the placement plane 28 when the cleaning head 12 is positioned as intended on the surface 16. When the cleaning head 12 is lifted, the spring force of the spring device causes the cleaning roller 32 to be pushed downwards beyond the placement plane until it reaches the end stop.

[0234] The surface cleaning apparatus 10 includes an active lifting device 250 (see DE 10 2024 103726.1, February 9, 2024) to lift the housing retainer 98 in a direction away from the placement plane 28, thereby spaced the cleaning roller 32, in particular, from the placement plane 28 and therefrom from the surface 16 (see...). Figure 14 In this position 252, the cleaning roller 32 does not touch the surface 16. This may be meaningful, for example, when performing pure carpet cleaning via the brush roller 30. The lifting device 250 can make the cleaning roller 32 inactive with respect to surface contact.

[0235] The corresponding position 252 may also be meaningful, for example, when the surface cleaning equipment 10, and especially the cleaning roller 32, is to be cleaned at a station (ground station).

[0236] In one embodiment, the lifting device is configured as a cable traction device 254. This cable traction device includes a traction cable 256. The traction cable 256 is connected via a fastening element 258 (…). Figure 9 It is fixed to the end side of the housing retainer 98.

[0237] Fastening element 258 is installed in the upper region at wall portion 234. This results in space-saving access.

[0238] The fastening element 258 is arranged, in particular, at least approximately centered, between the opposite ends of the housing retainer 98.

[0239] The cable traction device 254 also includes a motor with a transmission mechanism. This motor is located in the front region 56 of the cleaning head body 14, and particularly in the region of the battery device 70.

[0240] Regarding the longitudinal axis 40, in one embodiment, the motor is positioned between the receiving portion 58 for the sludge collection container and the front end portion 36 of the cleaning head body 14.

[0241] The motor is particularly positioned near the fan unit.

[0242] Furthermore, in one embodiment, the motor is arranged on the same side as the fan unit.

[0243] The traction cable 256 is guided along the housing 58 in the first region. Then, its direction is changed in the second region, which is specifically above the wind turbine unit.

[0244] Another directional change is made in the third region, and it is coupled to the motor.

[0245] By starting the motor and applying a corresponding pulling force to the traction cable 256, the housing retainer 98, which includes the housing 92 and the cleaning roller 32, can be raised. It is pulled upwards ( Figure 14 ), to reach position 252.

[0246] The motor maintains this position 252. In particular, it is configured to maintain this position 252 even when the motor is not running (not supplied with electrical power).

[0247] Furthermore, it is specifically designed that, in order to guide the device out of position 252 and to lower the housing retainer 98, a motor needs to be activated. The motor then causes the tension to be released by rotating in the opposite direction to the lifting direction, and the spring mechanism then induces the descent.

[0248] In one embodiment, the cable traction device 254 includes a pulley element (see DE 102024 103 726.1, February 9, 2024). The pulley element is arranged, for example, in a first region of the traction cable 256.

[0249] In one embodiment, the pulley element is arranged in the rear region 54 of the cleaning head body 14.

[0250] It is located particularly close to the 58th floor of the housing.

[0251] In addition to the cleaning roller 32 and side brooms 74a and 74b, the surface cleaning device 10 also includes a side cleaning tool 270. The side cleaning tool 270 is arranged on the housing 92 and can be removed from the cleaning head body 14 together with the housing 92.

[0252] The side cleaning tool 270 is used to wipe and clean the surface 16 to be cleaned between the end side 272 of the cleaning roller 32 and the second lateral side 82, and preferably beyond the second lateral side 82.

[0253] Side cleaning tool 270 has a loading area 274 (see, for example) Figure 2 The side cleaning tool 270 uses this loading area to act on the surface 16 to be cleaned. In the working position 276 of the side cleaning tool 270 (see...) Figure 12In this context, the loading region 274 is arranged with respect to the cleaning roller 32 such that the loading region touches the cleaning roller 32, or has a minimum spacing of 1 cm in a direction parallel to the rotation axis 96, or the loading region overlaps with the cleaning roller 32 (see [link]). Figure 2 ).

[0254] Side cleaning tool 270 is specifically designed as a wiping tool for wet wiping.

[0255] In one embodiment, the loading region 274 is formed of textile material and / or sponge material.

[0256] The side cleaning tool 270 is arranged on the housing 92 such that, when the housing 92 is fixed to the cleaning head body 14, the loading area 274 is positioned below the cover 90 for the opening 88 (when the cover 90 is closed), and here positioned between the placement plane 28 and the lower side of the cover 90 facing the placement plane 28 (see, for example, [reference needed]). Figure 1 ).

[0257] In one embodiment, the loading region 274 is configured to be "self-supporting". The side cleaning tool 270 has a holding region 278, at which the loading region 274 is secured (see, for example, see...). Figure 1 or Figure 7 The side cleaning tool 270 has a lower side 280 facing the placement plane 28. The lower side 280 is formed on the loading area 274 and spaced apart from the holding area 278, so that the holding area 278 does not act on the surface 16 to be cleaned.

[0258] Furthermore, the side cleaning tool 270 also has an outer side 282 through which the side cleaning tool protrudes from the second lateral side 82. The outer side 282 is also located at the loading area 274 and spaced apart from the holding area 278. When encountering, for example, a wall, the loading area 274 contacts the wall at the outer side 282, while the main holding area 278 does not.

[0259] In particular, the loading area 274 is accordingly constructed to be compressible due to its self-holding structure, so that under normal circumstances the holding area 278 does not come into contact with the surface 16 to be cleaned and does not come into contact with the wall or the like.

[0260] In one embodiment ( Figures 1 to 14 In the ), the loading area 274 of the side cleaning tool 270 is constructed as a disc, which is correspondingly installed in the holding area 278.

[0261] Here, it can be configured that the loading region 274 has a through opening 284 below the holding region 278 (see [reference]). Figure 2For example, the loading region 274 is fixed to the holding region 278 via the opening 284. Furthermore, the opening also allows the loading region 274 to have compressibility from the outer side 262 towards the opening 284.

[0262] The housing 92 includes a bearing retainer 286. The rotating bearing 182 is held in the bearing retainer 286 (see, for example, see...). Figure 7 The bearing retainer 286 is installed at the first end side 110 of the circumferential wall portion 106.

[0263] The side cleaning tool 270 is held on the housing 92 via the bearing retainer 286.

[0264] The bearing retainer 286 has a rear wall 288. The rotating bearing 182 is mounted on this rear wall 288 (see [reference]). Figure 8 The rear wall 288 is the rear wall of the housing 290. A shaft 292 is rotatably supported within the housing 290 (see also...). Figure 11 A motion axis 294 is associated with the shaft 292. In the working position 276 of the side cleaning tool 270, the motion axis 294 is oriented transversely to and, in particular, perpendicular to the placement plane 28.

[0265] The axis of motion 294 (in working position 276) is oriented laterally and, in particular, perpendicularly to the axis of rotation 96.

[0266] In one embodiment, the side cleaning tool 270 is configured to rotate about the axis of motion 294 during cleaning operation.

[0267] In an alternative implementation, the side cleaning tool 270 may be configured to operate in an oscillating manner during operation, and accordingly, the motion axis 294 may be an oscillating axis.

[0268] Shaft 292 is mounted in housing 290 adjacent to cleaning roller 32. The shaft is spaced apart from the nearest end of cleaning roller 32.

[0269] Regarding the direction parallel to the axis of rotation 96, the side cleaning tool 270 is a continuation of the cleaning roller 32, and the loading area 274 overlaps with or touches the cleaning roller 32 or has a minimum gap (in the working position 276). Accordingly, the shaft 292 is positioned at the bearing retainer 286 and within the housing 290.

[0270] The bearing retainer 286 includes a retaining plate 296 connected to the rear wall 288 and extending laterally to the rear wall (parallel to the axis of rotation 96).

[0271] The shaft 292 is positioned on the retaining plate 296, which also forms the wall of the housing 290, in a rotatable support manner.

[0272] Shaft 292 is transversely spaced from the axis of rotation 96. Figure 12 In the figure, the horizontal spacing is marked with reference numeral 298.

[0273] A side wall 300 is provided on the rear wall 288. The side wall 300 extends transversely to the rear wall 288 and is connected to the retaining plate 296 and the rear wall 288. When the housing 92 is mounted on the cleaning head body 14, the side wall 300 faces the housing retainer 98 and is away from the rear end 38.

[0274] The housing 290 also has an upper wall 302 opposite to the retaining plate 296. This upper wall is connected to the retaining plate 296 and the side wall 300. This upper wall is parallel to the retaining plate 296.

[0275] A receiving space 304 for the housing 290 is formed between the retaining plate 296, the side wall 300, the upper wall 302, and the rear wall 288. The shaft 292 is positioned in the receiving space 304 of the housing 290.

[0276] The axis of motion 294 is oriented laterally and, in particular, perpendicularly to the retaining plate 296.

[0277] Shaft 292 is supported not only on retaining plate 296 but also on opposite upper wall 302 in a manner that allows it to rotate about motion axis 294.

[0278] In one embodiment, the shaft 292 passes through the upper wall 302 via a corresponding opening in the upper wall 302 and has an end region 306 located outside the housing 290. Translational mobility of the shaft 292 in height can be manipulated via this end region 306. This will be explained in detail below.

[0279] Housing 290 through cover 308 ( Figure 7 The space is closed, wherein the accommodating space 304 is fluid-tightly closed.

[0280] In particular, the cover 308 is designed to not need to be removed during normal operation, and is especially impossible to remove without tools.

[0281] The housing 92 has a first end 310 and a second end 312 opposite to the first end 310. The second end 312 of the housing 92 is located at the cover 308.

[0282] When the housing 92 is positioned in the receiving portion 84, the first end 310 of the housing 92 is located in the region of the transverse wall portion 86. The second end 312 is located in the region of the opening 88. In particular, the cover 308 of the housing 290 is directly opposite the cover 90 of the receiving portion 84.

[0283] In one embodiment, the movement of the side cleaning tool 270 about the motion axis 294 is driven by the cleaning roller 32, and thus the main driving device is the drive motor 200.

[0284] For this purpose, a transmission device 314 is provided, which is positioned in the receiving space 304 of the housing 290. In one embodiment, the transmission device 314 includes a reduction gear mechanism so that the rotation of the side cleaning tool 270 about the motion axis 294 achieves a lower speed than the rotation of the cleaning roller 32 about the rotation axis 96.

[0285] Furthermore, in one embodiment, the transmission device 314 also includes an angular transmission device to achieve rotation about a motion axis 294, wherein the motion axis 294 is oriented transversely to the rotation axis 96. Additionally, the transmission device 314 includes a bridging transmission mechanism to cross a lateral spacing 298. (The lateral spacing 298 allows the housing 290 to be configured with a smaller size in a direction parallel to the rotation axis 96.)

[0286] In one embodiment, the transmission device 314 includes a belt drive mechanism 316. The belt drive mechanism 316 further includes a drive wheel 318. The drive wheel 318 is coupled to the rotary bearing 182 in a rotation-resistant manner and rotates about a rotation axis coaxial with the rotation axis 96.

[0287] The belt drive mechanism 316 also includes a driven pulley 320. The driven pulley 320 is supported in the receiving space 304 in a manner that allows it to rotate about the first axis of rotation 322, and is held therein, in particular, at the rear wall 288.

[0288] The first rotation axis 322 is parallel to and spaced apart from the rotation axis 96.

[0289] A belt 324 guides the drive wheel 318 and the driven wheel 320.

[0290] The first rotation axis 322 is oriented transversely to and preferably perpendicular to the rear wall 288.

[0291] In one embodiment, the belt drive mechanism 316 forms a speed reduction transmission mechanism. The driven pulley 320 has a larger diameter than the drive pulley 318.

[0292] In one embodiment, the belt 324 is guided parallel to the rear wall 288.

[0293] Within the receiving space, an intermediate shaft 326 is supported in a manner that allows it to rotate about a second axis of rotation 328. The intermediate shaft 326 is supported, in particular, in a rotatable manner at the retaining plate 296 and the upper wall 302.

[0294] The second axis of rotation 328 is parallel (and spaced apart from) to the axis of motion 294 of axis 292. The second axis of rotation 328 is transverse to and, in particular, perpendicular to the first axis of rotation 322.

[0295] A first gear 330 is mounted on the intermediate shaft 326, which can rotate about the second rotation axis 328.

[0296] In the described embodiment, the intermediate shaft 326 is rotatably arranged on the housing 290. In an alternative embodiment, the intermediate shaft 326 is arranged on the housing 290 with resistance to relative rotation, while the first gear 330 is supported relative to the intermediate shaft 326 about a second axis of rotation 328. In this embodiment, the intermediate shaft 326 is a stationary pin element.

[0297] A first angular transmission element 332 is arranged on the driven pulley 320 of the belt drive mechanism 316. The first angular transmission element 332 is rotatable about a first rotation axis 322. A first gear 330 constitutes a second angular transmission element 334, which is coupled to the first angular transmission element 332. Angular transmission of the transmission device 314 is realized via the first angular transmission element 332 and the second angular transmission element 334, by means of which rotation about the first rotation axis 322 can be converted into rotation about a second rotation axis 328. The first rotation axis 322 and the second rotation axis 328 intersect.

[0298] The angle transmission mechanism is constructed, for example, as a bevel gear transmission mechanism or a similar transmission mechanism.

[0299] A second gear 336 is mounted on shaft 292 in a manner that resists relative rotation. The second gear 336 is coupled to the first gear 330. Rotation of the first gear 330 about the second rotation axis 328 (introduced via belt drive mechanism 316 and transmitted via an angular drive mechanism having angular drive mechanism elements 332, 334) causes rotation of the second gear 336, and in turn, of shaft 292 carrying the side cleaning tool 270 about the motion axis 294. In particular, the rotational speed about the second rotation axis 328 is here equivalent to the rotational speed about the motion axis 294.

[0300] The first rotation axis 322 does not intersect with the motion axis 294, thereby realizing a bridging transmission mechanism for crossing the lateral spacing 298 via gears 330, 336 (and also via belt drive mechanism 316).

[0301] In the described embodiment, the side cleaning tool 270 is provided to rotate about the motion axis 294. When oscillation is provided, the transmission device 314 is then configured accordingly to convert the rotation of the cleaning roller 32 about the rotation axis 96 into oscillation about the motion axis 294.

[0302] The shaft 292 passes through the retaining plate 296 and is secured to the shaft 292 via the retaining area 278 of the side cleaning tool 270. In one embodiment, the side cleaning tool 270 is supported on the shaft 292 in a floating manner via a spring device 338. Thus, when the housing 92 pivots on the cleaning head body 12, as... Figure 14 As shown, this allows the side cleaning tool 270 to be properly positioned. This will be explained in more detail below.

[0303] In an alternative embodiment, the floating support of the side cleaning tool 270 on the shaft 292 is achieved by a joint, and in particular a universal joint (not shown in the figure).

[0304] The side cleaning tool 270 is supported on the housing 390 in a manner that allows for translation in both positioning and height. For this purpose, the shaft 292 is positioned such that it can move along the translational direction 340 (see...). Figure 12 The shaft 292 is supported on the housing 290 by means of translation. The support of the shaft 292 on the housing 290 is achieved, in particular, by means of a rotary-sliding bearing.

[0305] The translation direction 340 is parallel to the axis of motion 294. The rotary-sliding bearing is located at the upper wall 302 and the retaining plate 296.

[0306] A spring device 342 is provided for the shaft 292. In one embodiment, the spring device 342 comprises a helical spring mounted on the shaft 292. The spring device 342 is supported at the upper wall 302 and at the other end at the second gear 336.

[0307] The spring force of the spring device 342 causes the spring force to press the second gear 336 against the retaining plate 296 (see...). Figure 12 ), so that the side cleaning tool 270 is especially guided to its working position 276 ( Figure 12 )middle.

[0308] In order to move the side cleaning tool 270 away from the placement plane 28 by translating it vertically, the spring force of the spring device 342 must be overcome.

[0309] A drive unit 344 is provided to manipulate the axis 292, and thus the translation of the side cleaning tool 270, away from the placement plane 28. This drive unit is arranged on the cleaning head body 14 (see...). Figure 9 , Figure 10 ).

[0310] In one embodiment, the drive unit 344 includes a cable traction motor 346. The cable traction motor 346 is positioned on the cleaning head body 14 and, in particular, adjacent to the first lateral side 80. The cable traction motor is positioned, in particular, in the region of the housing retainer 98. The cable traction motor is positioned adjacent to the lateral wall portion 86.

[0311] A traction cable 348 is provided, which is coupled to a cable traction motor 346. The traction cable 348 is also coupled to a drive element 350. The drive element 350 (in the case of appropriate coupling) can act on a shaft 292.

[0312] The drive unit 344 also includes a reversing device 352, to which the traction cable 348 is guided from the cable traction motor 346 and to which the reversing device is used to reverse the direction of the traction cable 348 so as to enable vertical translation via the traction cable 348 in the translation direction 340.

[0313] The traction cable 348 has a portion 354 extending from the cable traction motor 346 to the reversing device 352. In this portion 354, the traction cable 348 is guided on the cleaning head body 14 outside the housing 92 and, particularly, along the housing 92 in the region of the housing retainer 98 (when the housing is fixed to the cleaning head body 14). In this portion 354, the traction cable 348 is oriented, at least approximately parallel to the axis of rotation 96.

[0314] The reversing device 352 is located in the region of the second end side 112 of the housing retainer 98 and away from the cable traction motor 346 located in the region of the first end side 110.

[0315] On the cleaning head body 14, the drive component 350 is guided on the guide device 356 in a translational manner.

[0316] In one embodiment, the guide device 356 is disposed within the housing 358 (see [reference]). Figure 10 The housing 358 is mounted on the cleaning head body 14 (rather than on the casing 92).

[0317] When the housing retainer 98 is not pivoted, the translation direction 360 of the drive member 350 on the guide device 356 is parallel to the translation direction 340 of the shaft 292.

[0318] In one embodiment, the guide device 356 includes a rod 362 on the cleaning head body 14, to which the drive element 350 is fitted.

[0319] The traction cable 348 is coupled to the drive member 350 via a separate section 364. This section 364 is located after the commutation device 352.

[0320] The traction cable 348 is coupled to the drive member 350 in a portion of the region 364 such that by applying tension to the traction cable 348 (via the cable traction motor 346), the drive member 350 can translate away from the placement plane 28 on the guide device 356 (rod 362).

[0321] Driven component 350 includes fork-shaped element 366 ( Figure 11 The fork-shaped element is configured as a gripper. The gripper includes an inlet opening 368, which is configured in a funnel shape.

[0322] The housing 92 has an interface 370 for coupling with the drive unit 344. The interface 370 is formed via an end region 306 of the shaft 292, which protrudes from the upper wall 302.

[0323] The end region 306 has a receiving region 372 for the fork-shaped element 366. In terms of the translation direction 340, shape locking is achieved when the fork-shaped element 366 is coupled, so that the shaft 292 (with the side cleaning tool 270) is also translated along with the translation of the fork-shaped element 366 via the drive member 350.

[0324] The drive element 350 is formed on the cleaning head body 14 with a mating interface 374 opposite to the interface 370 on the housing 92.

[0325] For this purpose, the drive component 350 extends from the housing 358 toward the opening 88.

[0326] Through the funnel-shaped inlet opening 368, when the housing 92 is placed into the receiving section 84, the receiving area 372 can be placed into the fork-shaped element 366, which serves as a gripper.

[0327] The fork-shaped element 366, which serves as a gripper, is configured such that the shaft 292 can move about the motion axis 294 on the drive member 350 when coupled with the drive member 350 (fork-shaped element 366).

[0328] By applying tension to the traction cable 348, the fork-shaped element 366 can be driven and thus lifted off the placement plane 28.

[0329] The spring device 342 ensures that when the tension applied to the traction cable 348 decreases, the second gear 336 re-enters its coupling position with the first gear 330.

[0330] When shaft 292 is lifted via drive device 344, second gear 336 is also lifted relative to first gear 330 (which cannot be translated within housing 290). Torque decoupling occurs. First gear 330 can no longer lift second gear 336, and movement of side cleaning tool 270 about axis of motion 294 is impossible.

[0331] The floor cleaning device 10 has been described above as a self-propelled and self-steering floor cleaning machine. In particular, the movable and especially spring-supported solutions for the "fixed flip cover" 144, the "push-release" fixing device 192, and the housing retainer 98 can also be applied, individually or in combination, to other types of floor cleaning devices, such as floor cleaning devices that are manually guided by a standing user via a handle device.

[0332] Furthermore, the arrangement of (at least one) side cleaning tool 270 for lateral continuation of the cleaning roller 32 and, in particular, for positioning on or driven via the cleaning roller 32, can also be applied to other types of floor cleaning equipment, such as those with a handle.

[0333] The working principle of the floor cleaning device 10 according to the present invention is as follows:

[0334] During the cleaning operation of the floor cleaning equipment 10, the housing 92, together with the side cleaning tool 270, is fixed in the receiving part 84. The cover 92 is closed.

[0335] During cleaning operation, the cleaning roller 32 rotates about the rotation axis 96. The lining 172 of the cleaning roller 32 is wetted by the cleaning liquid from the tank device 44 via the wetting device 140.

[0336] The cleaning roller 32 acts on the surface 16 to be cleaned (especially the ground). The dirt is partially dissolved and mechanically dissolved by the rotating cleaning roller 32. The dirt is peeled off and carried away by the lining 172 of the cleaning roller 32.

[0337] At the scraping device 166, the dirty fluid is stripped off and coupled via the port device 174 into the tank device 42 for the dirty fluid.

[0338] (Additionally, and especially in the case of pre-wet cleaning, cleaning can be performed via brush roller 30 and side brooms 74a, 74b.)

[0339] According to the invention, a side cleaning tool 270 is provided as an additional cleaning tool. The side cleaning tool is arranged next to the cleaning roller 32 about the axis of rotation 96, and in particular (at the second lateral side 82) protrudes beyond the outer side of the cleaning head body 14. The side cleaning tool 270 is configured with its loading area 274 for wiping cleaning. This increases the cleaning width of the floor cleaning device 10 for wiping cleaning. The corresponding "cleaning length" is greater than the length of the cleaning roller 32.

[0340] Furthermore, in a preferred embodiment, the side cleaning tool 270 extends sufficiently far to perform wiping cleaning in the strip 376 located next to the cleaning head body 14 on the second lateral side 82 (see [link]). Figure 1 ).

[0341] The side cleaning tool 270 is positioned in the housing 92 and located in the area of ​​the opening 88. The side cleaning tool can be removed from the cleaning head body 14 together with the housing 92 (see...). Figure 7 ).

[0342] In one embodiment, a second pump 379 is provided on the cleaning head body 14. Figure 1 The second pump is associated with the side cleaning tool 270. The second pump 379 is specifically fixedly positioned on the cleaning head body 14 in the rear region 54. The second pump is fluidly connected to the tank device 44 for cleaning fluid on the suction side. On the pressure side, the second pump is connected to a nozzle device, by means of which the side cleaning tool 270, and particularly its loading region 274, can receive cleaning fluid from the tank device 44. In this embodiment, the cleaning roller 32 and the side cleaning tool 270 can be supplied with cleaning fluid separately and thus independently of each other via the tank device 44.

[0343] Thus, it is possible, for example, to perform a cleaning process in which the side cleaning tool 270 is deactivated in terms of its cleaning function and the cleaning fluid is delivered only to the cleaning roller 32, or the cleaning roller 32 is deactivated while the side cleaning tool 270 is activated and the cleaning fluid is delivered only to the side cleaning tool 270, or both the cleaning roller 32 and the side cleaning tool 270 are activated in terms of their cleaning function and both are delivered cleaning fluid (see below).

[0344] In particular, the first pump 142 and the second pump 379 are driven by the control device according to the selected operating mode.

[0345] The nozzle device associated with the side cleaning tool 270 is arranged, for example, on the bearing retainer 286.

[0346] For example, it is also possible that shaft 292 is constructed as a hollow shaft, and the cleaning fluid is guided through the hollow shaft.

[0347] The cleaning roller 32 has a working position in which it is positioned on the placement plane 28. Figure 12 The housing retainer 98 is positioned accordingly. The side cleaning tool 270 has a working position 276 in which the side cleaning tool is positioned on the placement plane 28. Figure 12 ).

[0348] Figure 12 The diagram shows a view in which the loading area 274 of the cleaning roller 32 and the side cleaning tool 270 protrudes from the placement plane 28. In practice, the lining 172 of the cleaning roller 32 is compressed, and the loading area 274 is also compressed, so that they lie on the placement plane 28. (This compression is in...) Figure 12 (Not shown in the image.)

[0349] In the working position 276 of the side cleaning tool 270, the second gear 336 is pressed toward the retaining plate 296 by the spring device 342, and the second gear 336 is torque-coupled with the first gear 330.

[0350] The torque of the driven cleaning roller 32 is transmitted to the side cleaning tool 270 via the transmission device 314, causing the side cleaning tool to move and, in particular, rotate about the motion axis 294. This achieves the mechanical action of the side cleaning tool 270 on the surface 16 to be cleaned.

[0351] The torque of the cleaning roller 32 is transmitted to the first gear 330 via the belt drive mechanism 316 and the angular transmission device. The first gear 330 transmits its torque to the second gear 336 and thus to the side cleaning tool 270.

[0352] The side cleaning tool is held floatingly on the shaft 292 via a spring device 338.

[0353] Side cleaning tool 270 has a first rest positioning 378 ( Figure 13 In this first resting position 378, the side cleaning tool 270 is lifted relative to the placement plane 28, so that the side cleaning tool does not touch the surface 16 to be cleaned. The cleaning roller 32 is located on the placement plane 28.

[0354] To achieve the first rest position 378, the cable traction motor 346 is activated. This activation is specifically performed via a control device.

[0355] When the cable traction motor 346 is activated, a tension is applied to the traction cable 348. This tension is transmitted to the drive member 350, which has a fork-shaped element 366. Through the coupling of the fork-shaped element 366 with the receiving area 372, the shaft 292 can be raised (overcoming the spring force of the spring device 342).

[0356] In the first rest position 378, the second gear 336 is decoupled from the first gear 330. No torque is applied to the shaft 292, and no movement about the motion axis 294 occurs.

[0357] When the cable traction motor 346 is deactivated, the spring device 342 presses the second gear 336 downward, engaging it with the first gear 330, and causing it to reach the desired position according to... Figure 12 The job position is 276.

[0358] In the corresponding first resting position 378 of the side cleaning tool 270, the case retainer 98 may also swing at the swing bearing device 230 (see...). Figure 12 In this case, the cleaning roller 32 is lifted off the placement plane 28 and does not contact the placement plane.

[0359] The side cleaning tool 270 is supported by the spring device 338, allowing it to be held in its position where it rests against the retaining plate 296 (against the housing 290) from the outside (see...). Figure 14 ).

[0360] In particular, this positioning ensures that the side cleaning tool 270 does not touch the placement surface 28 even in this swing positioning.

[0361] Alternatively, there may be an additional position in which the housing retainer 98 is pivoted, thereby lifting the cleaning roller 32 from the placement plane 28. The side cleaning tool 270 descends and rests on the placement plane 28. This floating arrangement allows the surface 16 to be cleaned to be cleaned only via the side cleaning tool 270. For example, (when the surface 16 to be cleaned is the ground) this allows for a single movement in which only side cleaning occurs.

[0362] In principle, this leads to the following positions of the cleaning roller 32 and the side cleaning tool 270 on the cleaning head 14: - The cleaning roller 32 and the side cleaning tool 270 are in their respective working positions and act on the surface 16 to be cleaned, that is, they are located on the placement plane 28; - Both the side cleaning tool 270 and the cleaning roller 32 are lifted from the placement plane 28, and are thus deactivated in terms of their cleaning function for the surface 16 to be cleaned; - The cleaning roller 32 is positioned on the placement plane 28, while the side cleaning tool 270 is in the rest position; - The side cleaning tool 270 is in its working position 276, while the cleaning roller 32 is lifted from the placement plane 28.

[0363] Side cleaning tool 270 is located at position 92 of the housing.

[0364] With the housing 92 removed from the cleaning head body, the second gear 336 is coupled to the first gear 330 due to the action of the spring device 342 (see [link]). Figure 8 ).

[0365] The housing 92 can be inserted into the receiving portion 84 along the insertion direction 184. When correspondingly fixed by the fixing device 192, it is connected to the wetting device 140 at the interface 138. The drive motor 200 is torque-coupled to the cleaning roller 32 via the motor drive member 202. The port device 174 is coupled to the tank device 42 for dirty fluid. In addition, the shaft 292 is inserted into the mating interface 374 on the cleaning head body 14 at the interface 370 by being inserted into the fork-shaped element 366 through the inlet opening 368. Thus, the torque action of the side cleaning tool 270 and the cleaning roller 32 (and thus also the drive motor 200) is also coupled.

[0366] The lid can be closed at 90 degrees.

[0367] To remove the case 92 in the removal direction 186, the cover 90 is opened, and the case 92 with the side cleaning tool 270 can be released by pressing via the "push-release" mechanism and then removed.

[0368] According to the present invention, the wiping cleaning width is increased next to the cleaning roller 32 via the side cleaning tool 270. This makes it possible to perform near-edge wiping cleaning outside the contour of the cleaning head body 14.

[0369] By arranging the side cleaning tool 270 on the housing 92, simple positioning and cleanability of the cleaning tools 32 and 270 are achieved. The side cleaning tool 270 can be driven in a simple and space-saving manner via the driving of the cleaning roller 32.

[0370] The side cleaning tool 270 can be deactivated in a simple manner in terms of its application to the surface via the drive unit 344.
