[0013] The objective of this invention is to provide a floor cleaning machine of the type described at the beginning, which allows operators to perform optimized floor cleaning.

[0014] In the type of floor cleaning machine described at the beginning, this task is solved according to the invention by arranging a light source on the housing for illuminating the floor to be cleaned.

[0015] During the cleaning process, the housing is positioned above the ground, at least within a sub-range of the swinging working area of ​​the handle relative to the ground head. This allows for upward illumination of the ground using a light source. Consequently, the operator can easily assess the "dirtiness" of the surface to be cleaned.

[0016] In particular, a light source can provide a light cone that illuminates the ground around the ground head, thereby enabling optimized cleaning results. Furthermore, obstacles within the ground head's area can be better identified.

[0017] The grip lever can move relative to the ground head via a hinge. This allows the housing to also move relative to the ground head, and via the housing, the light source can also move relative to the ground head. This enables illumination of the ground in all positions of the grip lever relative to the ground head, or at least in sub-regions of possible positions, regardless of the grip lever's exact location relative to the ground head. (It is also possible that in "extreme" positions of the grip lever relative to the ground head, such as when the grip lever pivots relative to the ground head at the hinge to the edge of its swing range, the ground to be cleaned may no longer be illuminated.)

[0018] In one structurally advantageous embodiment, the light source is mounted on the lower side of the housing, facing the ground head. This allows for effective ground illumination within, or at least within, the swinging range of the grip (and consequently the hinge) relative to the ground head. Furthermore, the light cone can be directed specifically towards the ground head, thereby providing corresponding illumination brightness with relatively low energy consumption.

[0019] In one embodiment, the light source is arranged at a flange on the lower side of the housing assembly. In particular, a transition to the hinge mechanism is present in the region of this flange. Therefore, optimized arrangement of the light source is achieved while maintaining a simple structural design.

[0020] In one embodiment, at least one of the following is arranged on the housing device: (i) a battery device, (ii) in particular a tank device for cleaning fluid, and the light source is arranged on the same side of the housing device as the battery device and / or the tank device.

[0021] The battery and / or canister assembly on the housing gives the housing a relatively large "exterior portion." This provides space for the light source, enabling it to effectively illuminate the ground in front of the ground head.

[0022] For the same reason, it is advantageous to arrange the light source on the housing separately from the operator's side of the housing. This allows for effective illumination of the "main" working area of ​​the floor cleaning machine on the floor to be cleaned.

[0023] In particular, regarding the grip of the grip device, the light source and the battery device and / or especially the tank device for cleaning fluid are arranged on the same side of the housing device. This allows for effective illumination of the area in front of the ground head, and correspondingly, illumination of the ground to be cleaned in front of the ground head.

[0024] In one structurally advantageous embodiment, the light source is positioned below the battery unit along the longitudinal extension axis of the grip device. This allows the light source to be easily integrated into the housing. This provides effective illumination of the surface to be cleaned, particularly in front of the ground head.

[0025] Furthermore, it is particularly advantageous that, regarding the longitudinal extension axis, the distance between the light source and the battery device is at most 10 cm, and especially at most 5 cm. This results in a structurally simple design.

[0026] The floor cleaning head is equipped with a placement plane specifically designed for the floor to be cleaned. This is particularly advantageous when the light source's beam illuminates the placement plane within the swing range of the handle relative to the floor cleaning head, or within a sub-range of that swing range. This results in effective floor cleaning. Ideally, the light source's beam should illuminate the placement plane throughout the entire swing range. However, it is also possible, and without substantial operational limitations, to set this only for a sub-range of the swing range, and especially to eliminate illumination at extreme swing angles (at the edges of the handle's range of motion relative to the floor cleaning head). Such "extreme" swing angles are typically only rarely used in general floor cleaning processes.

[0027] It has been proven advantageous that the distance between the light source and the surface on which it is placed is at least 10 cm, and especially at least 15 cm. This provides effective illumination of the surface on which the light source is placed and the floor to be cleaned.

[0028] In particular, due to the mobility of the grip device and housing relative to the ground head, the light source, like the grip device (and housing), is also movable relative to the ground head. Therefore, the surface to be cleaned can be illuminated as effectively as possible without relying on the specific position of the grip device relative to the ground head.

[0029] Advantageously, within the swing working range or a sub-range of the swing working range, at least one of the following is provided: - The light cone of the light source illuminates the placement plane located in front of the front end of the ground head, where the front end is relative to the direction of travel of the ground head; - The front end of the light cone illuminates the ground head; - A placement plane next to the first lateral end of the light cone irradiating the ground head and / or next to the second lateral end, wherein the second lateral end is opposite to the first lateral end; - The light cone of the light source illuminates at least the sub-region of the ground head at the first lateral end and / or the second lateral end; - A light cone irradiation tank device, and especially an irradiation tank device for dirty fluid installed on the ground.

[0030] By illuminating the surface in front of the ground head with the light cone, the area of ​​the ground to be cleaned and the area in front of the ground cleaning machine that is about to enter can be effectively illuminated.

[0031] When the light cone illuminates the front end of the ground head, the ground head itself is also illuminated. This facilitates the operation for the operator.

[0032] For the same reason, it is advantageous that the placement plane next to one or two lateral ends of the ground head is illuminated by the light cone. This allows for effective cleaning with respect to lateral movement, or enables the operator to identify the presence of stains on the ground from the side of the ground head. The operator can also better identify obstacles on the sides.

[0033] When the light cone also illuminates the can unit on the ground, the filling level can be identified directly in an effective manner, or the can unit can be easily removed in a darker area (making it easier for the operator to find the handle).

[0034] In one embodiment, the light source is arranged on the housing wall adjacent to the hinge device. This provides both effective illumination of the floor to be cleaned and a structurally advantageous design. The space requirements for the light source within the housing are optimized.

[0035] For the same reason, it is advantageous to arrange the light source on the first housing wall, which is connected to the second housing wall, wherein the second housing wall is connected to the hinge portion of the hinge device, and the second housing wall, together with the housing device, can move relative to the ground via the hinge device. This allows the light source to be positioned near the hinge portion of the hinge device. This results in a space-saving arrangement that provides effective illumination of the cleaned floor "from above".

[0036] In particular, the light source includes multiple individual light sources (especially LEDs), and / or is equipped with a light panel. This allows for the realization of a light source with a certain length extension range, enabling effective illumination of the area in front of and to the sides of the ground head, especially within a large swinging working range of the grip device relative to the ground head.

[0037] In particular, at least one of the following is provided: - The light-transmitting panel is a light-blocking part; - The light plate includes a diffuser; - The light plate includes lenses; - The light panel includes multiple single light sources.

[0038] The light panel provides a light source over a relatively long length, enabling effective illumination of the area around the ground head, especially the front side of the ground head, where the surface to be cleaned.

[0039] More advantageously, the light source and its multiple individual light sources or light panels have a main extending axis that is transverse to and, in particular, perpendicular to the swing axis of the hinge portion of the hinge device. The light source is fixed about this swing axis, independent of the movement position of the grip device relative to the ground head. This results in an efficient structural design and effective illumination of the ground to be cleaned.

[0040] In particular, the length of the light source along the main extension axis is at least 5 cm, and especially at least 7 cm, and especially at least 8 cm.

[0041] Furthermore, advantageously, the housing assembly has a first lateral side and a second lateral side opposite to the first lateral side, and the light source is positioned between the first lateral side and the second lateral side and has a main extending axis parallel to the spacing direction between the first lateral side and the second lateral side. This results in an efficient, space-saving arrangement of the light source on the housing assembly. This provides effective illumination of the ground to be cleaned around the ground head.

[0042] In particular, regarding the distance between the first lateral side and the second lateral side, the light source is provided with a length on its main extension axis that is at least 50%, and especially at least 60%, and especially at least 70% of the distance. This provides effective illumination of the ground at the ground head, and in particular, effective illumination of the sides of the ground head.

[0043] In one embodiment, the light source is an LED spotlight, which can effectively illuminate the ground to be cleaned around the ground head.

[0044] Furthermore, it is advantageous that, regarding the housing assembly, the hinge is located between the light source and the operator's side of the grip assembly. This provides effective illumination of the area to be cleaned around the ground head, thereby enabling effective cleaning and the identification of obstacles on the ground.

[0045] Advantageously, a floor cleaning machine is provided, comprising: a floor head with a placement plane for the floor to be cleaned; a first disc holder and a first cleaning tool, wherein the first disc holder is disposed on the floor head and holds the first cleaning tool, and is driven to rotate about a first rotation axis during operation of the floor cleaning machine; a second disc holder and a second cleaning tool, wherein the second disc holder is disposed on the floor head and holds the second cleaning tool, and is driven to rotate about a second rotation axis during operation of the floor cleaning machine, wherein the first rotation axis of the first disc holder and the second rotation axis of the second disc holder are both oriented transversely to the placement plane; a fan device that generates a suction flow during operation of the floor cleaning machine; and a dirty fluid tank device for containing dirty fluid.

[0046] In one embodiment, the fan unit is arranged on the ground head, and the dirty fluid tank unit is installed on the ground head in a removable manner.

[0047] A suction flow is generated by a blower unit, which transports the dirty fluid to a dirty fluid tank unit. Both the dirty fluid tank unit and the blower unit are installed on the ground surface. This results in a short flow path.

[0048] By arranging the dirty fluid tank unit on the ground, a dirty fluid tank unit with a large capacity can be achieved. This, in turn, results in a longer service life.

[0049] By placing both the blower unit and the dirty fluid tank unit on the ground head, an optimized center of gravity distribution is achieved in the floor cleaning machine. This also results in simple maneuverability and good mobility.

[0050] Advantageously, the ground head has a ground head body on which the hinge device is mounted, wherein the ground head body has a plate-like area. This results in a structurally simple design.

[0051] Furthermore, it is advantageous to have at least one of the following features: - The grip device is hinged to the ground head in a universal joint manner through the hinge mechanism; - The hinge device includes a first hinge portion having a first swing axis and a second hinge portion having a second swing axis, wherein the first swing axis and the second swing axis are oriented transversely to and, in particular, perpendicular to each other, and the first swing axis is oriented parallel to the placement plane; - The first swing axis of the hinge is oriented transversely to, and in particular perpendicularly to, the direction of advance of the ground head.

[0052] The floor cleaning machine achieves good maneuverability through the universal joint support of the handle and hinge device.

[0053] In a simplified design embodiment, the hinge device includes a first hinge portion and a second hinge portion, each having a swing axis oriented perpendicularly to the other. This results in high maneuverability.

[0054] By orienting the first swing axis of the hinge device perpendicular to the direction of travel, the operator can adjust the tilt of the grip device relative to the ground to be cleaned in a particularly simple manner.

[0055] More advantageously, the first hinge portion of the hinge device is fixed directly or via a first retainer to the ground head body of the ground head, and the second hinge portion of the hinge device is mounted directly or via a second retainer on the first hinge portion, wherein, in particular, the second hinge portion is positioned above the first hinge portion with respect to a height axis perpendicular to the placement plane. This allows for efficient provision of accommodating space for the dirty fluid tank device on the ground head. The dirty fluid tank device can be implemented with a large accommodating volume for dirty fluid. The hinge device can be constructed with a simple design and the floor cleaning machine has high mobility.

[0056] More advantageously, the dirty fluid tank device has a notch, in which the hinge is at least partially located when the dirty fluid tank device is positioned on the ground head. This allows for the provision of a single dirty fluid tank device as a unit, which can be optimally secured to the ground head. The dirty fluid tank device can be implemented with a large accommodating volume. This results in an optimized arrangement of the hinge, particularly for the mobility of the floor cleaner and for the adjustability of the handle's angle relative to the surface to be cleaned. The notch provides space that allows the dirty fluid tank device to be constructed as a unit and to be optimally arranged on the ground head without hindering the movement of the handle relative to the ground head.

[0057] More advantageously, when the dirty fluid tank device is fixed to the ground, the first hinge portion of the hinge device is located within the notch such that the first swing axis is located within the notch, and the second hinge portion of the hinge device is positioned such that the second swing axis of the second hinge portion is located above the first swing axis about the height axis perpendicular to the placement plane, at least when the grip device is oriented perpendicular to the placement plane. This results in optimized mobility with a simple design of the hinge device.

[0058] More advantageously, a free space is arranged or formed at the ground head as a space for the swinging motion of the grip device relative to the ground head around a first swing axis, wherein the first swing axis is perpendicular to the direction of travel of the ground head. This results in high maneuverability. The tilt angle of the grip device relative to the surface to be cleaned can be easily adjusted by the operator, which provides a further range of swing for the grip device, and in particular, allows the grip device to be positioned at least approximately parallel to the surface to be cleaned about its longitudinal axis. The dirty fluid tank device can be configured to have a large capacity.

[0059] For the same reason, it is advantageous that when the dirty fluid tank device is fixed to the ground head, the free space is a continuation of the notch of the dirty fluid tank device, wherein the continuation line is perpendicular to the first swing axis.

[0060] In one structurally advantageous embodiment, a first column assembly, a second column assembly, and a third column assembly are positioned on the ground head body, wherein the first, second, and third column assemblies extend upward transversely to the ground head body. This allows for the space-saving installation of the corresponding components of the ground head, thereby enabling the realization of a dirty fluid tank assembly with a large capacity.

[0061] Herein, at least one of the following is specifically provided: - The first column assembly includes a fan assembly; - The second column assembly includes a drive mechanism for the first disc retainer and / or the second disc retainer; - The third column assembly includes a hinged assembly.

[0062] The corresponding components can therefore be arranged in a space-saving manner, and the dirty fluid tank device has a large capacity. The dirty fluid tank device can also achieve a large capacity for dirty fluids.

[0063] In particular, at least one of the following is provided: - The first column assembly, the second column assembly, and the third column assembly are spaced apart from each other; - A free space is formed between the first column assembly and the second column assembly, serving as a movement space for the grip assembly; - A receiving portion for the dirty fluid tank device is formed at least in a sub-region between the first column device and the third column device and between the second column device and the third column device; - The first column assembly, the second column assembly, and the third column assembly are located on an isosceles triangle, wherein the first column assembly and the second column assembly are located on the base of the triangle, and the third column assembly is located on the altitude of the triangle about the base, and wherein, in particular, the base is parallel to the first swing axis of the hinge assembly and / or the altitude of the triangle is perpendicular to the first swing axis.

[0064] This results in optimized space utilization at the ground level. The dirty fluid tank unit can be "placed" at the ground level, where it can be implemented with a large capacity.

[0065] Furthermore, it is advantageous to arrange at least one sub-region between the first, second, and third column assemblies for a torque transmission device to transmit torque from the drive unit to the first and second disc cages. This results in optimized space utilization. Optimal space utilization is particularly achieved when the torque transmission device is constructed in a "flat" manner. The dirty fluid tank assembly can then also be fixed to the ground above the torque transmission device.

[0066] Furthermore, it is advantageous that the first column assembly and / or the second column assembly have or form a contact area and / or a holding area for the dirty fluid tank assembly. This allows for a smaller number of components.

[0067] When the first column assembly is installed at the first corner area of ​​the ground head body and the second column assembly is installed at the second corner area of ​​the ground head body, the second corner area is opposite to the first corner area, resulting in optimized space utilization. This allows these column areas to be arranged to a certain extent at the edge area of ​​the ground head body, providing a larger capacity for the dirty fluid tank assembly on the ground head. This also enables the realization of a dirty fluid tank assembly with a large capacity for dirty fluids.

[0068] Advantageously, a drive mechanism for the first disc retainer and the second disc retainer is arranged on the ground head body of the ground head, particularly having at least one of the following: - A common drive motor is provided for the first disc cage and the second disc cage; - At least one drive motor is provided, which is vertically arranged on the ground head body such that its motor axis is oriented laterally and especially vertically relative to the perpendicular line of the placement plane or at an angle of up to 10°.

[0069] Therefore, optimized space utilization is achieved, and sufficient space can be provided for the dirty fluid tank device. This dirty fluid tank device can also be implemented with a large capacity for containing dirty fluids.

[0070] Furthermore, it is advantageous that a transmission housing is arranged on the ground head body of the ground head, the torque transmission device is positioned within the transmission housing, and the upper side of the housing forms a contact area and / or holding area for the dirty fluid tank device when it is fixed to the ground head. This results in optimized space utilization, which can then be used for the dirty fluid tank device.

[0071] In one embodiment, the dirty fluid tank device has a lower side, an upper side, a front side, a rear side, a first lateral side, and a second lateral side opposite to the first lateral side. The dirty fluid tank device has a notch that is through and open between the lower and upper sides, and that the notch opens rearward. Thus, the dirty fluid tank device can be positioned on the ground above the transmission device by means of this notch. This provides simple insertion and simple removal.

[0072] For the same reason, it is advantageous that the dirty fluid tank device has a first connecting arm region located on a first lateral side, a second connecting arm region located on a second lateral side spaced apart from the first connecting arm region, and a third connecting arm region connected to the first and second connecting arm regions, wherein a notch is formed between the first, second, and third connecting arm regions. The dirty fluid tank device thus forms an arcuate member that can be pushed over the hinge device.

[0073] Advantageously, at least one of the following is provided: - The rear side is located on the first connecting arm region and the second connecting arm region; - The front side is located on the third connecting arm area; - The dirty fluid tank device has a U-shape in the top view, and the first connecting arm region and the second connecting arm region are respectively the straight sides of the U-shape.

[0074] This results in optimized space utilization at ground level.

[0075] More advantageously, interfaces for fluid-operated connection with the fan unit are arranged in the first and / or second connecting arm regions. Specifically, the corresponding connecting arm region with this interface includes a ramp, and the fan unit on the ground head body is also equipped with a matching ramp. Thus, fluid-operated connection can be automatically achieved when the dirty fluid tank device is inserted into the ground head.

[0076] Furthermore, it is advantageous that the first connecting arm region has a first covering area and / or the second connecting arm region has a second covering area for covering the shell region on the ground head. This shell region is particularly the region of the column shell. Therefore, when the dirty fluid tank assembly is installed on the ground head, the ground head can be formed into a closed shape, and jumps and similar shapes can be avoided with respect to the external shape. In particular, a flush transition can be established between the sub-regions of the ground head and the dirty fluid tank assembly.

[0077] The ground head has a longitudinal axis extending between its front and rear ends, and this longitudinal axis is parallel to the direction of travel of the ground head. Advantageously, at least one of the following is thus provided: - The fan unit is installed in the rear section area; - The drive units for the first disc cage and the second disc cage are located in the area of ​​the rear end; - When the dirty fluid tank device is installed on the ground head, the front side of the dirty fluid tank device is located at the front end of the ground head; - The placement direction of the dirty fluid tank device on the ground head has a directional component that is parallel to the longitudinal axis and points towards the rear end.

[0078] This results in optimized space utilization for the installation of the dirty fluid tank unit on the ground surface. The dirty fluid tank unit can be easily removed and installed, and can be implemented with a large capacity for dirty fluids.

[0079] For the operator, it is advantageous to have at least one of the following settings: - The dirty fluid tank device includes a container and an openable, and in particular removable, lid; - The container and the lid of the dirty fluid tank device have essentially the same cross-sectional shape; - A swingable handle bow-shaped component is provided on the dirty fluid tank device, and especially on the container of the dirty fluid tank device; - The dirty fluid tank device has a retractable area for the submerged retaining handle bow-shaped part; - A gripping recess is provided on the front side of the dirty fluid tank device for gripping the handle bow-shaped part, especially the swinging handle bow-shaped part; - When the dirty fluid tank assembly is fixed to the ground head, the swing hinge portion for the handle bow-shaped part on the dirty fluid tank assembly is installed in the area of ​​the hinge device about the longitudinal axis of the ground head.

[0080] If the lid and container are essentially the same shape, then a larger access area can be provided for the container after the lid is removed. This allows for easy cleaning of the container, for example.

[0081] By arranging a swingable, bow-shaped handle, the dirty fluid tank unit can be easily removed from the ground.

[0082] The retracted area ensures that the handle bow-shaped component does not extend beyond the external contour of the dirty fluid tank unit, and reduces the risk of "snagging," including the dirty fluid tank unit accidentally detaching from the ground.

[0083] By arranging the swing-bearing mechanism for the handle bow in the area of ​​the hinge, the dirty fluid tank can be lifted obliquely upwards from the ground. This provides the operator with simple and easy operation in removing the dirty fluid tank.

[0084] In one embodiment, a removable tank for cleaning fluid is mounted on the handle. The cleaning fluid from this tank is delivered directly and / or via a cleaning tool to the surface to be cleaned. By arranging the tank for cleaning fluid on the handle, optimized space utilization is achieved. This results in an optimized center of gravity distribution.

[0085] For the same reason, it is advantageous to mount a battery pack on the handle, particularly below the tank assembly. The battery pack provides power to the power supplies of the floor cleaning machine.

[0086] Advantageously, the battery assembly and the container for the cleaning fluid are positioned on the same side of the handle assembly. This results in a simple design and optimized mass distribution.

[0087] For the same reason, it is advantageous that the side housing the battery and the container for the cleaning fluid is positioned away from the operator's side of the grip. This allows for a larger range of swing angles for the grip with respect to the surface to be cleaned. The grip can be implemented with a relatively small lateral dimension on the operator's side, thus enabling a larger range of swing and an orientation at least approximately parallel to the surface to be cleaned when the grip is at its maximum swing angle over the ground.

[0088] More advantageously, the battery assembly or the housing for the battery assembly forms the contact area and / or holding area for the cleaning fluid reservoir. This results in optimized space utilization. The number of required components can be kept to a minimum.

[0089] In one embodiment, the canister for cleaning fluid has a notch, and when the canister for cleaning fluid is mounted on the handle, the battery assembly and / or the housing for the battery assembly are submerged in the notch at least in a sub-region. Thus, a retainer with a shape-locking region can be easily implemented for the canister for cleaning fluid.

[0090] Therefore, it is advantageous to have at least one of the following features: - The canister for cleaning fluid has a lower side that faces the ground head when the canister for cleaning fluid is mounted on the handle, and the notch is arranged on the lower side; - The notch opens toward the front of the cleaning fluid canister, wherein the front is away from the handle of the handle when the cleaning fluid canister is mounted on the handle.

[0091] For the same reason, it is advantageous that the canister for cleaning fluid has a first connecting arm region, a second connecting arm region spaced apart from the first connecting arm region, and a third connecting arm region connected to the first and second connecting arm regions in the area of ​​the notch, wherein the notch is located between the first, second, and third connecting arm regions. This results in a structurally simple design for securing the canister for cleaning fluid to the handle device.

[0092] More advantageously, when the canister for the cleaning fluid is mounted on the grip assembly, the third connecting arm area is positioned between the battery assembly or the housing for the battery assembly and the grip arm of the grip assembly. This allows for a particularly simple form-locking fixation in the lateral direction relative to the longitudinal direction of the grip assembly.

[0093] In one embodiment, an electronic device box with circuitry is mounted on the grip assembly. This results in optimized space utilization.

[0094] Therefore, at least one of the following is specifically provided: - The electronic component box is located on the side opposite to the side having the container for cleaning fluid and / or the battery device.

[0095] This resulted in a simple design structure and efficient space utilization.

[0096] More advantageously, a conveying device is provided for delivering cleaning fluid from the cleaning fluid tank to the floor to be cleaned and / or to the first cleaning tool and / or the second cleaning tool. Specifically, the cleaning fluid tank is mounted on the handle assembly. The conveying device thus ensures that the cleaning fluid is delivered from the handle assembly (from the tank) to the floor. In particular, a portion of the conveying device is guided through the hinged assembly.

[0097] When the lever system includes a steering mechanism, it provides good maneuverability and operability for the operator. This steering mechanism, for example, has a first arm and a second arm, each of which can be gripped by one of the operator's hands.

[0098] More advantageously, at least one suction beam is arranged at the ground head, which is fluidly connected to the fan unit. The suction beam allows the fan unit to apply a suction flow to the surface to be cleaned, and in particular, it allows dirt to be carried into the dirt fluid tank at the ground head from behind the cleaning tools.

Detailed Implementation

[0101] An embodiment of the floor cleaning machine according to the invention, shown in the accompanying drawings and marked with 10, is particularly used for cleaning hard floors. The floor cleaning machine includes a floor head 12 and a handle assembly 14. The handle assembly 14 is connected via a hinged device 16 (see...). Figure 2 and Figure 3 It is hinged to the ground head 12.

[0102] Cleaning tools are arranged on the ground head 12, which will be described below. The handle 14 is used to enable the operator to stand on the ground 18 and face the operator side 20 of the floor cleaning machine 10 (see [link]). Figure 2 And especially for the upright operator facing the grip device 14 on the (step-on) ground 18 (see...) Figure 2 ) Guide the ground cleaning machine 10.

[0103] The ground head 12 includes a ground head body 22 (tool guard). The ground head body 22 has a lower side 24 and a upper side 26. A placement surface 28 is provided for the ground head 12. The placement surface 28 is defined by a plurality of support wheels 30 and cleaning tools.

[0104] During operation of the floor cleaning machine 10, the floor cleaning machine 10 as a whole passes through the ground head 12 via the support wheels 30. Figure 1 and Figure 4 The cleaning tools are supported on the floor 18 to be cleaned. If the floor 18 is flat, the placement plane 28 coincides with the floor 18 during the cleaning operation of the floor cleaning machine 10.

[0105] The lower side 24 of the ground head body 22 faces the placement plane 28.

[0106] The ground head 12 has a front end portion 32 and a rear end portion 34 on the ground head body 22. The ground head also has a first side end portion 36 and an opposite second side end portion 38. Between the front end portion 32 and the rear end portion 34, the ground head 12 (ground head body 22) has a longitudinal axis 40. During cleaning operation, the longitudinal axis 40 is parallel to the forward direction 42 of the ground head 12 (ground cleaning machine 10).

[0107] The ground head 12 (ground head body 22) is equipped with a transverse axis 44, which is perpendicular to the longitudinal axis 40.

[0108] The ground head 12 (ground head body 22) is also equipped with a height axis 46 ( Figure 1 The height axis 46 is perpendicular to the placement plane 28. The longitudinal axis 40 and the transverse axis 44 are perpendicular to the height axis 46, respectively.

[0109] When the floor cleaning machine 10 is in operation, the operator stands behind the rear end 34 of the floor head 12 and faces the operator side 20.

[0110] A first disc-shaped retainer 48 and a second disc-shaped retainer 50 are mounted on the ground head 12. The first disc-shaped retainer 48 is supported on the ground head body 22 in a manner that allows it to rotate about a first rotation axis 52. The first rotation axis 52 is transverse to the placement plane 28.

[0111] The second disc-shaped retainer 50 is supported on the ground head body 22 in a manner that allows it to rotate about the second rotation axis 54. The second rotation axis 54 is oriented transversely to the placement plane 28.

[0112] A first cleaning tool 56 is mounted on a first disc-shaped holder 48. The first cleaning tool can rotate via the rotation of the first disc-shaped holder 48. A second cleaning tool 58 is mounted on a second disc-shaped holder 50. The second cleaning tool 58 can rotate via the second disc-shaped holder 50.

[0113] The first cleaning tool 56 and the second cleaning tool 58 are arranged to rotate in opposite directions. In one embodiment, the first cleaning tool 56 and the second cleaning tool 58 are tilted relative to the placement plane 28 with their planes of action in between. Typical tilt angles are, for example, between 2° and 10°, particularly about 5°. This generates propulsion during the cleaning operation of the floor cleaning machine 10, wherein this arrangement results in propulsion in the forward direction 42. This facilitates the operator's guidance and maneuvering on the floor 18 to be cleaned.

[0114] The inclination of the working plane relative to the placement plane 28 can be achieved in principle by orienting the first rotation axis 52 and the second rotation axis 54 relative to the placement plane 28 at corresponding acute angles. The corresponding rotation axes of the first cleaning tool 56 and the second cleaning tool 58 then coincide with the first rotation axis 52 or the second rotation axis 54.

[0115] In an alternative embodiment, the rotation axis of the first cleaning tool 56 operates on a (hypothetical) conical circumferential side with the first rotation axis 52 as the conical axis, and the rotation axis of the second cleaning tool 58 operates on a (hypothetical) conical circumferential side with the second rotation axis 54 as the conical axis. The inclination angle of the working plane corresponds to the cone angle of the conical circumferential side.

[0116] The effective area of ​​the first cleaning tool 56 and the effective area of ​​the second cleaning tool 58 (in) Figure 1 (Indicated by reference numeral 60 in the attached drawing) protrudes from the ground head body 22 relative to the lower side 24, so that they can act on the ground 18 to be cleaned.

[0117] The first cleaning tool 56 and the second cleaning tool 58 are respectively configured as disc-shaped tools, and in particular as brush discs. In one embodiment, the first cleaning tool 56 and the second cleaning tool 58 are respectively brush-type tools, and the working area 60 is formed by the working area of ​​the brush (bristle bundle).

[0118] In principle, it is also possible that the first cleaning tool 56 or the second cleaning tool 58 has a textile action area, or that the cleaning tools 56 and 58 have both a brush action area and a textile action area.

[0119] The ground head body 22 has a first corner region 62 at its rear end 34 facing the second side end 38. The ground head body has a second corner region 64 at the first side end 36 and the rear end 34. A drive device for the disc retainers 48, 50 is arranged at the second corner region 64. The drive device includes one, and in particular exactly one, drive motor 66.

[0120] In one embodiment, drive motor 66 (see Figure 4 It is vertically arranged on the ground head body 22; it has a motor axis 68 (drive axis 68) which is oriented parallel to or at a small acute angle (especially less than or equal to 10°) relative to the height axis 46. The motor axis 68 is oriented transversely to and especially perpendicular to the placement plane 28 or at an angle of less than or equal to it.

[0121] A torque transmission device 70 is coupled to the drive motor 66 in a torque-acting manner. Through the torque transmission device 70, the torque of the drive motor 66 is transmitted to the first disc retainer 48 and the second disc retainer 50, and thus to the cleaning tools 56 and 58.

[0122] The torque transmission device 70 is positioned on the upper side 26 of the ground head body 22.

[0123] In one embodiment, the torque transmission device 70 includes a first gear 72 that is directly coupled to and directly driven by the drive motor 66 in terms of its rotation.

[0124] The first disc-shaped cage 48 is connected to the first gear 72 via the first belt drive mechanism 74 in a torque-acting manner.

[0125] A second gear 76 is also provided, which is torque-coupled to the first gear 72. The second gear 76 is directly driven by the first gear 72 in its rotational motion.

[0126] The second disc-shaped cage 50 is torque-coupled to the second gear 76 via the second belt drive mechanism.

[0127] This configuration of the torque transmission device 70 causes the first disc cage 48 and the second disc cage 50 to rotate in opposite directions, for which only a single drive motor 66 is provided at the second corner region 64.

[0128] The torque transmission device 70 is constructed to be flat. It is positioned within the transmission housing 80 (see...). Figure 3 In the above, the transmission housing 80 is positioned on the upper side 26 of the ground head body 22.

[0129] The transmission housing 80 includes: a first branch 82 in which a first belt drive mechanism 74 is positioned; and a second branch 84 in which a second belt drive mechanism 78 is positioned. Figure 4 The text points out that this is the second branch, number 84.

[0130] There is free space 86 between the first branch 82 and the second branch 84 (see, for example) Figure 3In this free space 86, the hinge device 16 is mounted on the ground head body 22 and connected to the ground head body.

[0131] In one embodiment, a slat 87 is mounted on the ground head body 22 in front of the front end 32. The slat 87 defines the foremost region of the ground head 12 relative to the direction of travel 42. It serves as a buffer to prevent the ground head 12 from impacting objects, walls, etc., or to mitigate impacts. The slat 87 is particularly made of an elastic material and / or is elastically supported.

[0132] The hinge device 16 is generally constructed in a columnar shape and extends from the ground head body 22 in a direction parallel to the height axis 46. It is fixedly connected to the ground head body 22 here.

[0133] In one embodiment, the hinge device 16 includes a first retainer 88. The first retainer 88 is mounted on the ground head body 22.

[0134] A first hinge portion 90 is mounted on the first retainer 88. The first hinge portion 90 is a swing hinge portion having a first swing axis 92. The first swing axis 92 is parallel to the placement plane 28. The first swing axis is transverse to, and in particular perpendicular to, the longitudinal axis 40. The first swing axis is parallel to the transverse axis 44. The first swing axis is transverse to, and in particular perpendicular to, the height axis 46. The first swing axis is transverse to, and in particular perpendicular to, the direction of travel 42.

[0135] The first hinge 90 enables the grip device 14 to pivot relative to the ground head 12, thereby changing the distance between the operator side 20 and the ground 18.

[0136] A second retainer 94 is mounted on the first hinge portion 90. A second hinge portion 96 is mounted on the second retainer 94.

[0137] The second hinge 96 is a swing hinge having a second swing axis 98. The second swing axis 98 is transverse to and, in particular, perpendicular to the first swing axis 92.

[0138] The second hinge portion 96 is connected to the first hinge portion 90 about the first swing axis 92 in a way that resists relative rotation, so that the second hinge portion swings about the first swing axis 92.

[0139] Regarding the height axis 46, the second hinge 96 is positioned above the first hinge 90.

[0140] The second hinge 96 is connected to the grip device 14 in a way that prevents relative swaying.

[0141] Thus, the grip device 14 can swing relative to the ground head 12 about the second swing axis 98 and about the first swing axis 92 on the hinge device 16.

[0142] By allowing the second swing axis 98 to swing around the first hinge 90, its orientation relative to the placement plane 28 is changed. The second swing axis 98 moves within a plane perpendicular to the placement plane 28.

[0143] The orientation of the first swing axis 92 relative to the placement plane 28 remains unchanged.

[0144] The hinge device 16 enables a universal joint-type hinge between the grip device 14 and the ground head 12.

[0145] The first retainer 88 is arranged on the ground head body 22 closer to the front end 32 than to the rear end 34.

[0146] In one embodiment, the first retainer 88 is spaced apart from the front end portion 32 along the longitudinal axis 40.

[0147] The first retainer 88 is centrally located between the first side end 36 and the second side end 38.

[0148] A fan unit 100 is arranged on the ground head body 22. The fan unit 100 is installed in the first corner area 62 (see...). Figure 4 ).

[0149] The fan unit 100 includes a fan motor and at least one impeller.

[0150] During operation of the floor cleaning machine 10, the fan unit 100 generates a suction flow for drawing in dirty fluid.

[0151] Here, dirty fluid is understood as a flowable fluid that can be carried away in a suction flow. Dirty fluid can be liquid or dry.

[0152] A suction beam 102 is arranged on the ground head body 22 (see, for example, see...). Figure 4 The suction beam is positioned in the region at the rear end 34.

[0153] During the cleaning operation of the ground head 12, the suction beam 102 rests against the ground 18 to be cleaned. Here, with respect to the direction of travel 42, the suction beam is positioned behind the cleaning tools 56 and 58.

[0154] The fan unit 100 is fluidly connected to the suction beam 102, and the suction beam is loaded with suction flow.

[0155] The dirty fluid behind the cleaning tools 56 and 58 can then be sucked away by the suction beam 102, and the sucked-away dirty fluid is coupled into the dirty fluid tank device 104.

[0156] The fan unit 100, located in the first corner region 62, and the drive motor 66, located in the second corner region 64, are spaced apart from each other about the transverse axis 44. There is free space 106 between them, which will be described further below.

[0157] A first column assembly 108 is mounted on the ground head body 22 in an extension direction parallel to the height axis 46. The first column assembly 108 includes a fan assembly 100. The first column assembly includes a first column housing 110 in which the fan assembly 100 is positioned.

[0158] Furthermore, a second column assembly 112 is arranged on the ground head body 22 at the second corner region 64. The second column assembly includes a second column housing 114. The second column assembly 112 includes a drive motor 66, which is positioned within the second column housing 114.

[0159] A third post device 116 is also positioned on the ground head body 22. This third post device is spaced apart from the first post device 108 and from the second post device 112. The third post device 116 is a hinge device 16.

[0160] As described above, the third column device 116 is centrally located between the first side end 36 and the second side end 38.

[0161] The free space 106 (which is also the free space in the region of the rear end 34 between the first post assembly 108 and the second post assembly 114) is the space of motion for the grip assembly 14, especially in terms of its swingability around the first swing axis 92.

[0162] The hinge device 16 is configured such that it can move in free space 106 together with the second retainer 94 and the second hinge portion 96.

[0163] This allows for a small angle between the grip 14 and the ground 18. This, in particular, provides maneuverability under furniture or similar objects. With a small angle to the ground 18, the total height of the device along the height axis 46 is determined by the height of the ground head 12.

[0164] In the side view, when the dirty fluid tank device 104 is removed, the ground head 12 has an L-shaped shape, which has a ground head body 22 and column devices 108, 112 extending upward transversely to the ground head body.

[0165] The first column assembly 108, the second column assembly 112, and the third column assembly 116 are located on triangle 118 (see...). Figure 2 Triangle 118 has a base 120, on which the first pillar 108 and the second pillar 112 are located. Triangle 118 has an altitude perpendicular to the base 120, which is in particular parallel to the longitudinal axis 40. A third pillar 116 is located on this altitude.

[0166] Triangle 118 is an isosceles triangle.

[0167] The space for the swingability of the grip device 14 around the first swing axis 92 is located on the height of triangle 118.

[0168] The second swing axis 98 is located in a plane that includes the elevation line and is perpendicular to the placement plane 28.

[0169] The dirty fluid tank device 104 is a unit that can be removed from and fixed to the ground head 12 as a whole. It collects dirty fluid, especially that sucked away from the surface 18 to be cleaned, by means of the blower device 100.

[0170] In one embodiment, the separator is integrated into the dirty fluid tank device 104.

[0171] The dirty fluid tank device 104 includes a container 122 and an openable lid 124. In particular, the lid 124 can be removed from the container 122 as a whole to allow for greater access to the container 122.

[0172] In one embodiment, the cap 124 is secured to the container 122 by a releasable latching connection 126.

[0173] The dirty fluid tank device 104 has a lower side 128. This lower side is located on the container 122. When the dirty fluid tank device 104 is fixed to the ground head 12, the lower side 128 of the dirty fluid tank device 104 faces the upper side 26 of the ground head body 22.

[0174] The dirty fluid tank device 104 also has an upper side 130 opposite to the lower side 128. The upper side 130 is located on the cover 124.

[0175] The dirty fluid tank device 104 also has a front side 132 and a rear side 134 opposite to the front side.

[0176] Between the front side 132 and the rear side 134, the dirty fluid tank device 104 has a first lateral side 136 and an opposite second lateral side 138.

[0177] When the dirty fluid tank device 104 is fixed on the ground head 12, the first lateral side 136 is located at the first lateral end 36 of the ground head 12, and the second lateral side 138 is located at the second lateral end 38.

[0178] The dirty fluid tank device 104 matches the shape of the ground head 12 having the ground head body 22 in its external shape. In one embodiment (see...) Figure 9 The first lateral side 136 is retracted relative to the first lateral end 36. This also applies to the case where the second lateral side 138 is retracted relative to the second lateral end 38. Thus, between the ground head body 22 and the dirty fluid tank device 104, regions 139 are formed on the ground head body 22. Figure 9 This area allows for better drillability.

[0179] Regarding the external envelope, the dirty fluid tank device 104 has at least an approximate cuboid shape.

[0180] A handle bow-shaped component 140 is arranged on the container 122, and in particular directly below the lid 124. The handle bow-shaped component is mounted on the swing bearing 144 in a manner that allows it to swing about the swing axis 142.

[0181] In one embodiment, the oscillating bearing 144 includes portions mounted on a first lateral side 136 and a second lateral side 138.

[0182] When the dirty fluid tank assembly 104 is fixed to the ground head 12, the swing axis 142 is parallel to the first swing axis 92 of the hinge assembly 16. This swing axis is parallel to the placement plane 28.

[0183] The swing axis 142 is oriented laterally to the first lateral side 136 and laterally to the second lateral side 138.

[0184] The handle bow-shaped component 140 includes opposing connecting arms 146a and 146b, which are respectively connected to the swing bearing 144. The connecting arms 146a and 146b are interconnected via a connecting arm 148.

[0185] The handle bow-shaped part 140 has a U-shaped design, in which the connecting arms 146a and 146b are equivalent to the straight edges of the U-shape.

[0186] In the unpivoted position of the handle bow-shaped component 140, the connecting arm 148 is positioned on the front side 132 of the dirty fluid tank device 104 (see...). Figure 3 ).

[0187] A gripping recess 150 is provided on the front side 132 of the container 122 (and / or the lid 124). Through the gripping recess 150, the operator can access the connecting arm 148 and thus the handle bow 140 so that the handle bow can pivot about the swing axis 142.

[0188] In one embodiment, container 122 has a groove 152. When the handle bow 140 is not pivoted, the handle bow is partially sunk into the groove 152, such that the handle bow does not extend beyond or substantially does not extend beyond the front side 132 and the lateral sides 136, 138.

[0189] When the dirty fluid tank device 104 is fixed to the ground head 12 (see...) Figure 1 The oscillating bearing 144 is spaced apart from the placement plane 28 on the height axis 46. The oscillating bearing 144 is positioned on the ground head 12 in the area of ​​the hinge device 16.

[0190] The dirty fluid tank assembly 104, having a handle bow-shaped component 140, is arranged and designed such that when the dirty fluid tank assembly 104 is fixed to the ground head 12, the operator can swing the handle bow-shaped component 140 upwards along direction 154 (see...). Figure 1 The dirty fluid tank device 104 is pulled upward and forward from the ground head 12, and thus removed from the ground head 12.

[0191] The dirty fluid tank assembly 104 has a notch 156 that matches the hinge assembly 16 and its positioning on the ground head body 22. When the dirty fluid tank assembly 104 is placed on the ground head 12, the notch 156 corresponds to the free space 106.

[0192] The notch 156 is through between the lower side 128 and the upper side 130 of the dirty fluid tank assembly 104. It opens toward the rear side 134.

[0193] The notch 156 is located on both the lid 124 and the container 122.

[0194] The dirty fluid tank assembly 104 includes a first connecting arm region 158. A first lateral side 136 is located on the first connecting arm region 158. The dirty fluid tank assembly 104 also includes a second connecting arm region 160. A second lateral side 138 is located on the second connecting arm region 160. The first connecting arm region 158 and the second connecting arm region 160 are spaced apart from each other.

[0195] The rear side 134 is located on the first connecting arm region 158 and the second connecting arm region 160.

[0196] The dirty fluid tank device 104 also includes a third connecting arm region 162. The third connecting arm region 162 is oriented laterally to the first connecting arm region 158 and the second connecting arm region 160. The third connecting arm region is connected to both the first connecting arm region 158 and the second connecting arm region 160.

[0197] The dirty fluid tank device 104 is made to have at least approximately a U-shape through the connecting arm regions 158, 160, and 162, wherein the first connecting arm region 158 and the second connecting arm region 160 correspond to the straight sides of the U-shape.

[0198] The connecting arm areas 158, 160, and 162 include both container 122 and lid 124.

[0199] The gap 156 is formed between the first connecting arm region 158, the second connecting arm region 160, and the third connecting arm region 162. The third connecting arm region 162 forms the boundary of the gap 156 facing forward 132.

[0200] Within the connecting arm regions 158, 160, and 162, a container volume for containing dirty fluid is formed at the container portion 122 of these connecting arm regions 158, 160, and 162.

[0201] An interface 164 for fluid connection with the fan unit 100 is arranged on the second arm region 160.

[0202] In one embodiment, the mating interface 166 of the fan unit 100 positioned on the ground head body 22 is located on the inclined surface 168 (see [reference]). Figure 3 The second connecting arm region 160 has a matching ramp 170 in the region of the interface 164, and the interface 164 is located on the ramp.

[0203] When the dirty fluid tank device 104 is placed on the ground head 12 as specified, the matching ramps 170 and 168 automatically generate a fluid connection with corresponding fluid sealing between the interface 164 and the mating interface 166.

[0204] A covering area 172 is arranged on the first connecting arm region 158. When the dirty fluid tank assembly 104 is installed on the ground head 12, the first connecting arm region 158 is oriented toward the second column assembly 112. The covering area 172 covers a sub-region of the second column housing 114. When the dirty fluid tank assembly 104 is installed on the ground head 12, the transition portion 174 from the dirty fluid tank assembly 104 to the second column housing 114 (see...) Figure 1 It is flush and, in particular, without sharp edges (see Figure 1 ).

[0205] Accordingly, the second connecting arm region 160 is provided with a covering region 176, which covers the sub-region of the first column housing 110, in particular, where the mating interface 166 is installed, so as to achieve a transition without edges or a flush transition.

[0206] When the dirty fluid tank device 104 is fixed to the ground head 12, the hinge device 16 is positioned in the notch 156.

[0207] The notch 156 can achieve this in a direction 178 that includes a directional component parallel to the longitudinal axis 40 and pointing from the front end 32 to the rear end 34 (see...). Figure 2 Place the dirty fluid tank device 104 onto the ground head body 22 and push it over the hinge device 16.

[0208] When the dirty fluid tank device 104 is fixed to the ground head 12, the notch 156 extends from the hinge device 16 to the rear end 34 into the free space 106, so as to provide space for the swingability of the grip device 14 at the hinge device 16.

[0209] The dirty fluid tank device 104 has a relatively large capacity and is designed to match the ground head body 22 with column devices 108, 112 and 116 (hinged device 16).

[0210] The dirty fluid tank device 104 can be inserted into the ground head body 22 with a component parallel to direction 178, and can be removed in the opposite direction, especially in direction 154 (which has a component antiparallel to direction 178 and a component parallel to the height axis 46).

[0211] The ground head body 22 and its upper side 26, and especially the transmission housing 80, form a contact surface and a retaining surface for securing the dirty fluid tank assembly 104 to the ground head 12. These contact / retaining areas provide, in particular, downward support about the height axis 46.

[0212] The first column device 108 and the second column device 112 form an abutment / holding area relative to the rear end 34.

[0213] In particular, a form-locking and / or force-locking connection is provided to fix the dirty fluid tank device 104 to the ground head 12. The form-locking and / or force-locking connection requires a certain amount of force after fixing so that the dirty fluid tank device 104 can be removed from the ground head 12 in the direction 154 and in particular to prevent accidental loosening.

[0214] The grip assembly 14 includes a grip 180. The grip 180 has a longitudinally extending axis 182. The grip is connected at its distal end to a hinge assembly 16, and in particular to a second hinge portion 96.

[0215] At the proximal end, a steering mechanism 184 is mounted on the grip lever 180 for the operator.

[0216] In one embodiment, the height of the grip device 14, which is the distance between the proximal end of the grip 180 and the steering gear 184, can be adjusted in particular via a movable steering gear.

[0217] The steering mechanism 184 has arms 186a and 186b. The operator can grip these arms with their hands.

[0218] A display device and / or an operating device 188 is arranged between arms 186a and 186b.

[0219] A housing device, marked as an integral part, is mounted on the handle 180. In the described embodiment, the handle 180 is connected to the hinge device 16, and the housing device 190 is held by the handle 180. Thus, the handle 180 is an important structural component of the floor cleaner 10.

[0220] In principle, it is also possible that the housing 190 is connected to the hinge 16, and a corresponding handle is mounted on the housing. In this example, the housing is a crucial structural component (“spine”) of the floor cleaner 10.

[0221] The housing assembly 190 is positioned between the steering gear 184 and the second hinge 96. The housing assembly is designed such that it does not substantially restrict the mobility of the grip lever assembly 14 relative to the ground head 12.

[0222] A battery device 192 is mounted on the grip device 14. The battery device 192 is positioned above the ground head 12.

[0223] In one embodiment, the battery assembly 192 is mounted on a retainer 194. The retainer 194 is connected to a handle 180.

[0224] The grip 180 has a side 196 facing the operator. The battery assembly 192 is mounted on a side 198 facing away from this side 196.

[0225] When the grip device 14 is arranged vertically (see...) Figure 1 The battery device 192 faces forward.

[0226] The housing assembly 190 has a housing portion 200, within which the battery assembly 192 is protectively positioned (in) Figure 1 In the middle, the housing portion 200 was removed.

[0227] The housing portion 200 is closed on the sides and on the underside 202 towards the ground head 12.

[0228] On the grip 14, on the retainer 204 (see...) Figure 9 The container 206 for the cleaning fluid is detachably mounted on the device. The cleaning fluid is, in particular, water, and, if necessary, a surfactant-containing cleaning agent additive.

[0229] The canister assembly 206 is detachably mounted on the grip assembly 14 between the lower side 202 of the housing assembly 190 and the steering gear 184. The canister assembly 206 is mounted on the side 198, just like the battery assembly 192, and is located away from the operator side 20.

[0230] The can assembly is positioned above the battery assembly 192 at least in sub-region 208.

[0231] The canister assembly 206 is a unit that can be removed as a whole from the floor cleaner 10 (from the handle assembly 14, i.e., from the retainer 204). It has a lower side 202 that faces the floor head 12.

[0232] The can assembly 206 has a notch 210 in the region of the lower side 202, which is located below the sub-region 208. The notch 210 is configured to allow the sub-region of the battery assembly 192 to extend therein.

[0233] In the region of the notch 210, the tank device 206 has a first connecting arm region 212, a second connecting arm region 214 opposite to the first connecting arm region, and a third connecting arm region 216 connected to the first connecting arm region 212 and the second connecting arm region 214.

[0234] The can assembly 206 has an approximately U-shaped shape at its notch 210, wherein the first connecting arm region 212 and the second connecting arm region 214 form the straight edge of the U-shape.

[0235] The notch 210 opens towards the front side 218 of the tank assembly 206.

[0236] There is a receiving space 220 between the battery assembly 192 and the grip 180 (see Figure 9 When the can assembly 206 is fixed to the handle assembly 14, the third connecting arm region 216 is located in the receiving space 220.

[0237] The notch 210 of the can device 206 is located at the holding region 222 of the can device 206. The holding region 222 allows the can device 206 to be inserted into the housing portion 200 where the battery device 192 is mounted. This allows for a form-locking fixation, at least in the lateral direction with respect to the longitudinal extension axis 182 of the relative handle 180.

[0238] In one embodiment, another connection method with the grip 180 can be provided, such as a force-locking connection or a snap-locking connection, to achieve fixation in a direction parallel to the longitudinal extension axis 182.

[0239] The tank assembly 206 is formed by a holding region 222 and a sub-region 208. In particular, the holding region 222 and the sub-region 208 are integrally or one-piece connected. This provides a larger capacity for the cleaning fluid.

[0240] In one embodiment, a gripping recess 224 for gripping a can device 206 as a unit is arranged on the sub-region 208.

[0241] The floor cleaning machine 10 includes a delivery device 226 for delivering cleaning fluid to the floor 18 to be cleaned. Specifically, the cleaning fluid is delivered from the tank 206 to the cleaning tools 56, 58. The delivery device 226 is connected to the tank 206. A corresponding interface is provided on the retainer 204, thereby automatically establishing a fluid-acting connection (especially providing controllability for the delivery of cleaning fluid to the floor head 12), particularly when the tank 206 is properly secured to the retainer 204.

[0242] In one embodiment, the portion of the conveying device 226 that guides from the housing device 190 to the ground head 12 is arranged within the hinge device 16 (see [link]). Figure 1 (The hinge device 16 is not shown there).

[0243] To transport the cleaning fluid from tank 206 to ground head 12 via conveyor 226, a pump may be provided, or the transport may be gravity-driven and controlled, for example, by a solenoid valve. The transport volume can be adjusted, in particular, via display / operating device 188.

[0244] The can assembly 206 matches the housing portion 200 in its external shape, thereby achieving a flush continuity, in particular, when the can assembly 206 is fixed to the handle assembly 14.

[0245] The grip device 14 includes an electronics box 228 in which circuitry is protected.

[0246] In one embodiment, at least one circuit board having corresponding electrical / electronic circuit components is arranged in the electronic device box 228.

[0247] In particular, the electronic device box 228 is mounted on the handle 180 away from the battery device 192 and away from the canister device 206.

[0248] In one embodiment, rollers 230 are arranged on the ground head 12 in the area of ​​the rear end 34. These rollers are used to transport the floor cleaning machine 10 outside of cleaning operations. In one embodiment, support wheels 30 are positioned between these rollers. The rollers 230 are spaced apart from the placement plane 28.

[0249] The floor cleaning machine 10 is equipped with a light source 302 ( Figures 10 to 13 The light source 302 is used to illuminate the floor 18 to be cleaned during the cleaning operation of the floor cleaning machine 10. This allows the operator to identify stains on the floor 18. Furthermore, the operator can identify obstacles on the floor 18.

[0250] The light source 302 is arranged on the housing assembly 190, and on the housing portion 200, and further arranged on the lower side 202 (see [reference]). Figure 10 Regarding the longitudinal extension axis 182, the light source 302 is positioned below and particularly close to the battery device 192.

[0251] In one embodiment, the distance between the light source 302 and the battery device 192 with respect to the longitudinal extension axis 182 is at most 10 cm, and in particular at most 5 cm.

[0252] The light source 302 and the battery device 192 are arranged on the same side of the housing device 190. Thus, the light source is positioned on the housing device 190 away from the operator side 20.

[0253] The light source 302 is mounted on the first housing wall 304, which is the housing wall on the lower side 202. The first housing wall 304 faces the ground head 12.

[0254] The first housing wall 304 is connected to the second housing wall 306, and the second housing wall is connected to the second hinge portion 96.

[0255] The lateral dimension of the second hinge portion 96 is smaller than that of the housing portion 200 on the lower side 202 of the housing device 190. The first housing wall 304 forms a transition portion to the second housing wall 306, and the second housing wall 306 forms a transition portion to the second hinge portion 96.

[0256] The first housing wall 304 forms a flange of the housing device 190, which faces the ground head 12. The light source 302 is arranged on the flange.

[0257] The light source 302 is positioned here in the front region 308 of the first housing wall 304. This front region 308 is opposite to the operator side 20. The hinge device 16 is located between the front region 308 and the operator side 20.

[0258] (When the grip device 14 is positioned such that its longitudinal extension axis 182 is perpendicular to the placement plane 28) the distance between the light source 302 and the placement plane 28 is at least 10 cm, and especially at least 15 cm. This allows for effective illumination of the cleaned floor 18 from above.

[0259] The housing assembly 190 has a first lateral end portion 310 and an opposing second lateral end portion 312 in the region of the housing portion 200. The front region 308 of the first housing wall 304 extends between the first lateral side 310 and the second lateral side 312.

[0260] The light source 302 is positioned between a first lateral end portion 310 and a second lateral end portion 312. The light source 302 may be associated with a main extension axis 314, which is either in the direction of the distance between the first lateral end portion 310 and the second lateral end portion 312, or parallel to this distance direction. The light source 302 has a greater length on the main extension axis 314 than that perpendicular to the main extension axis. The corresponding length of the light source 302 on the main extension axis 314 is at least 50% and, more particularly, at least 60% of the distance between the first lateral end portion 310 and the second lateral end portion 312. This results in effective illumination.

[0261] The light source 302 is fixed relative to the second swing axis 98, that is, the orientation of the second swing axis 98 in relative space with the main extension axis 314 is fixed and is independent of the positioning of the grip device 14 with respect to the first swing axis 92.

[0262] In particular, the main extension axis 314 and the second swing axis 98 are transverse to and preferably perpendicular to each other.

[0263] In one embodiment, the light source 302 includes a light plate 316 having an extension range in the direction of the main extension axis 314. The light plate 316 provides a large illumination area. In principle, the light source 302 may include multiple single light sources, and in particular multiple single LEDs. They are arranged on the housing device 190, especially behind the light plate 316. The light plate 316 provides an effective surface light source.

[0264] In principle, the light plate 316 can be configured as a shield, especially for a single light source, or several single light sources can be directly and protectively arranged on the light plate 316.

[0265] The light plate 316 can here be configured as a diffuser, and particularly additionally or alternatively includes a lens, in order to produce a defined light cone 318 (see [link to document]). Figure 11 In particular, the generated light cone 318 is independent of the positioning of the housing device 190 relative to the ground head 12 (the orientation of the light cone 318 relative to the placement plane 28 or the ground 18 to be cleaned can vary here; see...). Figures 11 to 13 ).

[0266] In principle, the light source 302, and thus the light cone 318, is configured such that the light cone illuminates the placement plane 28 of the environment surrounding the ground head 12. Specifically, this illumination of the placement plane 28 by the light cone 318 is situated within a wide range of motion (oscillation range) of the handle 14 relative to the ground head 12. It is possible that, at extreme oscillation angles, this illumination may cease at the edges of the primary possible oscillation range. At least for the commonly used oscillation angle range of the floor cleaning machine 10 relative to the ground head 12, the illumination of the placement plane 28 by the light cone 318 is provided.

[0267] The light source 302 is arranged and configured such that, within the working range or part of the working range (with regard to the swingability of the grip device 14 relative to the ground head 12), the light cone 318 illuminates the placement plane 28 (and thus the ground 18 to be cleaned) in front of the front end 32, and also involves the front end 32. Thus, the front area of ​​the ground head 12 is also illuminated.

[0268] Furthermore, the light cone 318 also illuminates the area on the placement plane 28 adjacent to the first side end 36 and the second side end 38, and also illuminates the sub-areas of the ground head 12 at the first side end 36 and the second side end 38 (see...). Figure 12 ).

[0269] Additionally, the light source 302 may be arranged and configured such that, at least in the initial position 320, the dirty fluid tank device 104 is also illuminated from above. This facilitates, for example, the removal or placement of the dirty fluid tank device 104 on the ground head 12.

[0270] In addition, the operator may also be able to directly identify the filling level at the tank device 104.

[0271] exist Figure 12 The diagram shows a position where the grip assembly 14 is pivoted relative to the ground head 12, and here pivots only about the first swing axis 92. With respect to the second swing axis 98, the grip assembly 14 is in its initial position and is not swinging.

[0272] According to Figure 12In this second position, the light cone 318 still illuminates the placement plane 28 in front of the front end 32 and next to the side ends 36 and 38.

[0273] Figure 13 The image shows another position in which the grip device 14 pivots about the second swing axis 98 and does not pivot about the first swing axis 92, that is, with respect to the first swing axis 92, the grip device 14 is still in its initial position.

[0274] According to Figure 13 In this third position, the light cone 318 also illuminates the placement plane 28 in front of the front end 32.

[0275] Under this pivot, it is possible that the light cone 318 will no longer illuminate the first lateral end portion 36, and will no longer illuminate the placement plane next to the first lateral end portion 36.

[0276] The floor cleaning machine 10 according to the present invention operates as follows: During cleaning operations, tank device 206 is mounted on handle device 14, and dirty fluid tank device 104 is mounted on ground head 12.

[0277] The operator operates the floor cleaning machine 10 via the grip device 14 with a steering mechanism 184, and stands on the operator side 20 behind the floor cleaning machine 10.

[0278] The cleaning tools 56 and 58 are driven to rotate in opposite directions by the drive motor 66. The tilt of the cleaning tools relative to the placement plane 28 generates propulsion.

[0279] The operator can adjust the swing angle at the first hinge 90 and the second hinge 96 and match it according to the cleaning process, and in particular, can also perform steering.

[0280] Cleaning tools 56 and 58 rotate and act on the floor 18 to be cleaned.

[0281] The cleaning fluid is delivered from the tank device 206 to the floor 18 to be cleaned via the delivery device 226, and is first applied to the cleaning tools 56, 58.

[0282] The dirty fluid is guided away via the suction beam 102. The corresponding suction flow is generated by the blower unit 100. The dirty fluid is coupled into the dirty fluid tank unit 104 on the ground head 12.

[0283] The electrical energy required, especially for driving the motor 66 and the fan unit 100, is provided by the battery unit 192.

[0284] After the cleaning process is completed, the operator can remove the dirty fluid tank device 104 in direction 154 via the handle bow 140.

[0285] In the solution according to the invention, both the fan assembly 100 and the dirty fluid tank assembly 104 are arranged on the ground head 12. This results in a short fluid path for the dirty fluid. Furthermore, center of gravity optimization is also achieved.

[0286] The dirty fluid tank device 104 is provided with a notch 156. Thus, on the one hand, a dirty fluid tank device 104 with a large capacity can be provided, and on the other hand, optimized positioning on the ground head 12 is achieved without hindering the mobility of the grip device 14 on the hinge device 16.

[0287] The blower unit 100 and drive motor 66 are positioned at the edge of the ground head 12 by being arranged in the corner area 64 or 62, so that they do not provide substantial limitation on the containment volume of the dirty fluid tank unit 104.

[0288] The corresponding column assemblies 108 and 112, with corresponding column housings 110 and 114, also provide a contact area / holding area for fixing the dirty fluid tank assembly 104 on the ground head 12.

[0289] This results in a compact and space-saving structure.

[0290] By arranging the battery device 192 on the grip 14 and the can device 206 on the grip 14 with the battery device 192 located below the can device 206, a lower center of gravity is achieved. Specifically, the can device 206 and the battery device 192 are arranged on the same side of the grip 14. Together with the grip 14, they are pivotable in terms of their swayability at the hinge 16.

[0291] The lever assembly 14 (along with the battery assembly 192 and the canister assembly 206) has a large range of motion relative to the ground head 12. This allows for good compatibility with the special cleaning requirements of the floor cleaning machine 10, which has "obstacles" to the surface to be cleaned, while maintaining the high mobility of the floor cleaning machine 10.

[0292] The floor cleaning machine 10 is equipped with a light source 302 (work light), which is specifically configured as an LED spotlight. The light source 302 is used to illuminate the floor 18 to be cleaned. This allows the operator to identify the degree of contamination of the floor 18 in front of the floor head 12, and also to identify the area beside the floor head 12, at least within a certain range of swing angles. The operator can also identify obstacles on the floor 18 to be cleaned.

[0293] The light cone 318 of the light source 302 illuminates the area of ​​the ground to be cleaned in front of the ground head 12 within the entire working range or a large working range of the grip device 14 relative to the ground head 12.

[0294] The light source 302 is integrated into the housing device 190 in a space-saving manner and is arranged on its lower side 202 facing the ground head 12. This provides effective illumination of the ground 18 to be cleaned (from above) and, if necessary, at least one sub-area of ​​the ground head 12.
