[0011] WO 2016 / 141963 A1 discloses a vacuum cleaner with a housing extending along an axis of extension between a first housing side and a second housing side. A suction unit for generating a suction flow is provided and is arranged in the housing. Furthermore, a separator device is arranged in the housing.

[0012] The invention is based on the object of providing a separator container device of the type mentioned at the beginning, which allows effective dirt separation.

[0013] This object is achieved according to the invention in the separator container device mentioned at the outset in that an inlet device for a dirty fluid flow is arranged on the cover device, wherein the receiving space is filled via the cover device, and that an outlet device for an air flow is arranged on the cover device.

[0014] The solution according to the invention allows coarse dirt to be effectively separated from fine dirt in the separator container device and, in particular, also to separate liquid.

[0015] By coupling the dirty fluid flow to the cover device, a filter device can be continuously flushed during operation of the cleaning machine with the separator-container device. Furthermore, a coarse dirt collection area can be dried using the applied negative pressure.

[0016] Furthermore, a large receiving volume is created for the receiving chamber. The receiving chamber and other flow-exposed elements of the separator-container device can be designed to be "smooth," effectively preventing dirt from getting stuck in cracks or similar.

[0017] An outlet for an air stream is arranged on the cover assembly. This results in a compact design and allows for effective separation. The cover assembly forms a kind of communication center for fluid in the separator-container device. A dirty fluid stream is coupled in via the inlet assembly on the cover assembly and then fed to a filter assembly, particularly in the form of a filter basket. The inlet assembly on the cover assembly allows for effective coupling to a blower assembly, and a suction flow can be easily achieved.

[0018] The separator-container device is, in particular, a separator-container device designed to be loaded with a liquid-laden contaminated fluid. In particular, the container can then also hold contaminated fluid, i.e., the container has a collecting space for contaminated fluid.

[0019] For the same reason, it's advantageous to have a connection for the cleaning machine's blower unit on the cover. This results in a compact design and allows for easy connection to the cleaning machine.

[0020] It is advantageous if the inlet device on the cover device comprises a connection for the cleaning machine for coupling in a dirty fluid flow, or if at least one flow pipe is fluidly connected or connectable to the inlet device on the cover device, which flow pipe has a connection for the cleaning machine for coupling in a dirty fluid flow. This effectively allows for the implementation of an interface for transferring a dirty fluid flow from the cleaning machine to the separator-container device. The coupling from the cleaning machine takes place directly into the cover device or via the at least one flow pipe.

[0021] It is advantageous if at least one of the following is provided: the container base is continuous and without openings and / or connections; the container base is designed as a plate and in particular as a flat plate and / or flat plate.

[0022] This allows the container to be made "smooth" on the inside, effectively preventing dirt and other contaminants from sticking. This allows for easy emptying of a filled container and also makes it easy to clean. Furthermore, it offers a large capacity.

[0023] In an advantageous embodiment, at least one flow tube is assigned to the inlet device on the cover device, which is or can be fluidly connected to the cover device. The flow tube serves to guide a dirty fluid flow and couple it into the cover device at the inlet device. Dirty fluid, in particular, can be transported through the flow tube against the direction of gravity. The flow tube provides a simple and compact interface for connecting to the cleaning machine.

[0024] It is particularly advantageous if the at least one flow tube is positioned outside the receiving space. This allows a contaminated fluid flow to be effectively coupled to the inlet device of a lid device and into the container via the lid device. Furthermore, cracks and the like, where contaminated fluid can settle, can be largely avoided in the receiving space. Furthermore, a compact design is achieved.

[0025] It is advantageous if at least one of the following is provided: the at least one flow pipe is designed as a riser pipe, wherein in a normal operating state, a dirty fluid flow in the at least one flow pipe has a flow component opposite to the direction of gravity; in a normal operating state, the cover device is positioned above the container bottom with respect to the direction of gravity; exactly one flow pipe is provided.

[0026] The design of at least one flow tube as a riser pipe results in a compact structure, for example, when mounted on a support rod device of a hand-held cleaning machine. By designing the flow tube as a riser pipe or standpipe, dirty fluid can be effectively supplied to the cover device, and from the cover device, a liquid-laden dirt stream can then flow downward into the container under gravity.

[0027] Furthermore, it is advantageous if at least one of the following is provided: with respect to a vertical axis of the receiving space, the at least one flow pipe is positioned next to the receiving space and / or next to the container base and / or next to the container wall; with respect to a transverse direction to a vertical axis of the receiving space, the at least one flow pipe is spaced from the container base and / or spaced from the receiving space and / or spaced from the container wall; the inlet device on the lid device is positioned offset from the receiving space and / or offset from the container base in a transverse direction to a vertical axis of the receiving space; the at least one flow pipe and / or the inlet device on the lid device is positioned decentrally to the container base;The inlet device on the cover device is positioned outside a projection surface of the receiving space, wherein the projection surface is perpendicular to a height axis of the receiving space; the at least one flow pipe runs, at least when the separator-container device is positioned on the cleaning machine, at least approximately parallel to a height axis of the receiving space; the at least one flow pipe runs, at least when the separator-container device is positioned on the cleaning machine, along the container wall.

[0028] The arrangement of the flow tube next to the receiving chamber, the tank floor, or the tank wall results in a compact design, effectively reducing the accumulation of dirt in the tank. This allows for easy coupling of the dirty fluid to the lid assembly.

[0029] Furthermore, it is advantageous if the at least one flow pipe is arranged and designed such that a main flow direction for dirty fluid when flowing through the at least one flow pipe is at least one of the following:

[0030] (i) parallel to a vertical axis of the receiving space; (ii) transversely and in particular perpendicularly to the container bottom;

[0031] (iii) extends in a direction parallel to a direction from the container bottom to the lid means.

[0032] This results in effective flow guidance. It also creates a compact design. A large storage volume can be provided for the container.

[0033] It is advantageous if the at least one flow pipe has an inlet and an outlet, wherein the outlet is connected or connectable to the inlet device on the cover device, and wherein the inlet is connected or connectable to the cleaning machine. This results in an effective transfer of dirty fluid from the cleaning machine to the separator-container device with the possibility of coupling to the inlet device on the cover device.

[0034] It is furthermore advantageous if at least one of the following is provided: the outlet is arranged at a first end of the at least one flow pipe; the inlet is arranged at a second end of the at least one flow pipe; a sealing device is assigned to the outlet; a sealing device is assigned to the inlet; the inlet is at the same height as the container base with respect to a height axis of the receiving space or is offset from the container base with respect to the height axis; a fluid-effective coupling of the separator-container device to the cleaning machine takes place at the inlet; the at least one flow pipe extends from the inlet to the cover device.

[0035] This results in an effective coupling of the separator-container device to the cleaning machine for coupling and separation at the separator-container device.

[0036] In one embodiment, at least one of the following is provided: the at least one flow tube is connected to the container and in particular is non-detachably connected; the at least one flow tube is positioned on an outer side of the container or in the region of an outer side of the container; the at least one flow tube is connected to the container wall and / or integrated into the container wall; the at least one flow tube is integrally connected to the container wall; the at least one flow tube is seated on a casing of the container.

[0037] The at least one flow pipe is then an integral part of the container. The lid device can then be detached from the at least one flow pipe when it is removed from the container. In particular, it is provided that a handle is arranged on the container and that at least one flow pipe is positioned on the container facing away from the handle, wherein in particular the receiving space is positioned between the handle and the at least one flow pipe with respect to a transverse direction to a vertical axis of the receiving space. This results in a compact design. In particular, the separator-container device with the flow pipe can be positioned internally on a receptacle of the cleaning machine in order to obtain an effective interface for transferring dirty fluid.

[0038] It is advantageous if the at least one flow tube is located at a central plane of the container, with a vertical axis of the receiving space being located in the central plane, and in particular with a handle of the container being located at the central plane. This results in a compact design. The separator-container device can be easily attached to or removed from a cleaning machine.

[0039] In one embodiment, the container wall has a flat side on which the at least one flow tube is positioned, and in particular, a handle on the container is positioned facing away from the flat side. This results in a compact design. The separator-container device can be effectively attached to a cleaning machine. A large storage volume can be provided.

[0040] In one embodiment, the container has a recess on the flat side for the at least one flow tube. This results in a compact design. In particular, the lid device is detachable from the at least one flow tube to allow access to the container.

[0041] It can also be provided that the at least one flow tube is fixed to the lid device. In particular, the lid device with the at least one flow tube is then detachable from the container and, in particular, removable. It is fundamentally possible for the flow tube itself to be detachable from the lid device. If the lid device is connected to the container, the flow tube can also be connected to the container by a particularly detachable connection, such as one or more clamps.

[0042] Furthermore, it is possible for the at least one flow pipe to be part of the cleaning machine, and in particular for the separator-container device to be removable from the at least one flow pipe. In particular, the at least one flow pipe then remains attached to the cleaning machine.

[0043] Advantageously, a clean side of the separator-container device is located on the cover device, and a dirty side of the separator-container device is located on at least one flow pipe or on the cover device. The clean side of the separator-container device is connected, in particular, directly to a blower device. The dirty side of the separator-container device is connected to the cleaning machine via the flow pipe or directly via the cover device. The dirty-side connection provides the interface for introducing a dirty fluid flow from the cleaning machine into the separator-container device.

[0044] In particular, the lid device is positioned on the container in such a way that it can be opened and, in particular, is removable from the container as a whole. This allows the container to be easily emptied. Furthermore, a filter basket positioned on the container can also be easily removed. In one embodiment, the lid device has a receptacle for a (first) filter device, on which the filter device is mounted, in particular, in a removable manner. This allows, in particular, a dry stream of dirt to be filtered.

[0045] It is advantageous if at least one of the following is provided: the filter device is or comprises a fine dust filter and / or motor protection filter; a clean side of the filter device is located at an outlet device of the cover device for an air flow; the filter device comprises a flat pleated filter.

[0046] The separator container device is preferably directly coupled to a blower device of the cleaning machine via the cover device, meaning that a suction flow is applied via the cover device. This suction flow may be particularly contaminated with fine dust. The (first) filter device ensures appropriate filtration and thus motor protection.

[0047] In particular, the receptacle is open to an upper side of the lid device, which faces away from the container bottom, and in particular, the (first) filter device can be removed upwards from the upper side. This results in a simple, compact design with easy removal. Furthermore, a structurally simple connection of the separator container device to the blower device on one side results.

[0048] It is particularly advantageous if at least one deflection pipe is arranged on the cover assembly, which is fluidly connected to the inlet assembly. The deflection pipe allows for a flow deflection. This directs a stream of contaminated fluid into the container. This, in turn, allows for a simple separation effect.

[0049] It is advantageous if the at least one deflection pipe has an outlet, in particular with at least one of the following: the outlet faces the container bottom; the outlet has an opening normal which is oriented parallel or at an acute angle of less than 30° to a height axis of the receiving space; the outlet has an opening normal which is oriented transversely and in particular perpendicularly to the container bottom; the outlet has an opening normal which is oriented parallel or at an acute angle of less than 30° to the container wall; the outlet has an opening normal which is oriented parallel or at an acute angle of less than 30° to at least one flow pipe; the inlet device is arranged on the cover device on the at least one deflection pipe; the at least one deflection pipe is arranged and designed such thatthat a main flow direction for dirty fluid when flowing out of the outlet is oriented opposite to, or at an acute angle of less than 30° to, a main flow direction of dirty fluid when coupled to the inlet device on the cover device and / or to a main flow direction in at least one flow pipe. The dirty fluid flow can be introduced via the outlet, in particular into a filter basket. This makes it easy to achieve liquid separation, so that, in particular, an air flow to a blower device does not entrain liquid. A coarse dirt container can be continuously flushed via the dirty fluid flow. This increases the time until the coarse dirt container becomes clogged with dirt. Furthermore, coarse dirt can be effectively dried in the coarse dirt container due to the applied negative pressure. Fine dirt can bind in liquid and be transported away.

[0050] Relative to a vertical axis of the container's receiving space, a (first) filter device, particularly for dry dust, is positioned above the at least one deflection pipe. This results in an effective structure. The cover device thus forms a kind of fluid communication center for the separator-container device.

[0051] It is particularly advantageous if a (second) filter device with at least one filter basket is provided, which is assigned to the cover device, wherein a dirty fluid flow, which is coupled via the inlet device on the cover device, is directed into the filter basket and in particular is directed completely into the filter basket. The filter basket forms a coarse dirt collection container. The complete introduction of the dirty fluid flow, which may contain liquid, results in a permanent flushing of the filter basket. This increases the time until the filter basket becomes blocked. Fine dirt can partially bind in the liquid and is then carried along and positioned in the container. Furthermore, the filter basket is permanently exposed to a negative pressure, resulting in effective drying.

[0052] The filter basket creates an effective separator, filtering out coarse dirt from a contaminated fluid stream coupled in (via the cover assembly) and collecting it. Liquid can drip off and be collected in the receiving chamber. This allows the airflow, which is coupled in particular into the cover assembly for discharge (directly coupled to the blower assembly), to be realized as dry, since the amount of liquid entrained in the airflow is minimized.

[0053] In particular, the at least one filter basket comprises a basket base, a basket wall, and a basket space between the basket base and the basket wall. This results in a simple and compact design.

[0054] It is particularly advantageous if a collecting space for dirty liquid is formed in the container between the container bottom and the basket bottom. This collecting space for dirty liquid is a partial area of ​​the container's receiving space. This makes it possible to provide a liquid-air-coarse dirt separator. Coarse dirt is collected in the filter basket. Liquid that has flowed through the filter basket is collected in the partial area of ​​the receiving space below the filter basket. This makes it possible to smooth the flow in order to ensure effective liquid dripping and, in particular, to effectively prevent liquid from being entrained by an air stream (which is discharged outside the filter basket in particular). The solution according to the invention makes it possible to provide a relatively dry (dirt-laden) air stream outside the filter basket, which is then discharged in particular via a first filter device.

[0055] It is particularly advantageous if a mesh is arranged on the basket wall and / or the basket base. The mesh defines which dirt particle sizes are retained. The filter basket thus functions as a sieve basket. The mesh (sieve) also ensures that the flow is smoothed. This, in turn, allows liquid to drip off and not be dragged along with the air stream. This creates a relatively dry (dirt-laden) air stream, which is then discharged, in particular, via a first filter device.

[0056] It is advantageous if the mesh size of the mesh is between 50 and 300 microns. This results in an effective coarse dirt collection function with effective separation and flow smoothing functions.

[0057] In particular, an outlet of at least one deflection pipe, which is fluidly connected to the inlet device on the lid device, opens into the basket chamber, and in particular along a central axis of the basket chamber. This effectively allows a dirty fluid flow from the lid device to be transferred to the container, with coarse dirt collection, liquid collection, and separation functions.

[0058] In particular, the basket bottom faces the container bottom in order to achieve a compact and structurally simple design.

[0059] In one embodiment, at least one spacer for a basket holder is arranged on the basket base and / or at least one spacer for the basket base is arranged on the basket holder. This allows the filter basket to be positioned at a distance from a corresponding receiving base of the basket holder, and a flow can occur between the basket base and the receiving base.

[0060] It is particularly advantageous if a basket holder is provided for the at least one filter basket, which is connected to the container and / or the lid device and, in particular, is detachably connected. The basket holder holds the filter basket and can also have additional functions, such as holding a splash guard, providing a drip tray, holding a sensor, and so on. It is advantageous if at least one of the following is provided: the basket holder is removable from the container and / or the lid device; the at least one filter basket is removable from the basket holder.

[0061] This results in effective emptying of the separator container device and easy cleaning.

[0062] In particular, the basket holder is a separate element from the lid device, in particular having at least one of the following: the basket holder is releasably seated on the container; the lid device is releasably positioned on the basket holder from the container and the basket holder.

[0063] This makes it easy to empty and clean.

[0064] It is particularly advantageous if the basket holder holds at least one filter basket in such a way that at least a portion of the basket wall is immersed in the receiving space of the container. This results in effective flow guidance with a compact design.

[0065] It is also advantageous if the basket holder has a receptacle for the at least one filter basket, which receptacle has a receptacle base, a receptacle wall, and a receptacle space between the receptacle base and the receptacle wall. This results in a simple structure. A coarse dirt collection function can be provided in a simple manner. Furthermore, a separator can also be easily implemented in this way, which in particular carries out coarse dirt separation and liquid separation. It is particularly advantageous if the receptacle base and the receptacle wall of the receptacle are closed and at least one outlet opening, and in particular precisely one outlet opening, is provided for fluidic connection to the receptacle space of the container. This results in a defined flow guidance, which results in an effective separation effect.The at least one outlet opening is a window of the receptacle into the receiving space of the container. Through appropriate arrangement and design, a "drip" of liquid from the receptacle into the receiving space of the container can be effectively achieved. An airflow pattern can be achieved that allows a substantially dry airflow to be provided at an outlet device of the separator-container device.

[0066] It is advantageous if at least one of the following is provided: the at least one outlet opening is arranged on the receiving wall; the at least one outlet opening extends as far as the receiving base; the at least one outlet opening has an extension in a circumferential direction over an angular range of at least 10° and in particular at least 15°; the at least one outlet opening has an extension in a circumferential direction over an angular range of at most 40°; the at least one outlet opening faces a side of the container on which at least one flow pipe is positioned; the at least one outlet opening faces a side of the container which is opposite to a side with a handle; the at least one outlet opening faces a side which, when the separator-container device is properly inclined to the direction of gravity, is at the top with respect to the direction of gravity.

[0067] The appropriate design of the at least one, and in particular precisely one, outlet opening results in an effective separation function. Furthermore, the appropriate design of the outlet opening allows the separator-container device to achieve a substantially inclination-independent reception and separation function. For example, the separator-container device can be operated even if the vertical axis of the container's reception space is not parallel to the direction of gravity, but is perpendicular to the direction of gravity, for example.

[0068] In one embodiment, the basket holder has a flange on which a receptacle for at least one filter basket is located, with the flange being provided to cover the container. Effective airflow guidance can be achieved via the flange. Furthermore, it is possible to empty the container through corresponding openings in the flange while the basket holder is attached to the container. This results in a structurally simple design.

[0069] It is advantageous if at least one through-opening is arranged on the flange, with at least one of the following: the at least one through-opening establishes a fluid-effective connection to an outlet device for an air flow, wherein in particular the outlet device is arranged on the cover device; through the at least one through-opening, the receiving space of the container can be emptied when the cover device is removed without removing the filter holder.

[0070] The container can be emptied via the at least one through-opening without having to remove the basket holder. Furthermore, an airflow connection to the lid device can be provided via the at least one through-opening to effectively discharge an airflow or enable a suction flow.

[0071] It is particularly advantageous if the at least one passage opening on the flange is fluidly adjacent to at least one outlet opening on a receptacle for the at least one filter basket. This allows a (contaminated) air flow to be discharged via the at least one passage opening, in turn enabling an effective clean-side coupling to a blower device, i.e., providing a clean-side interface to a cleaning machine.

[0072] It is particularly advantageous if an airflow-effective connection (in particular via the at least one passage opening) between the outlet device and the container is positioned outside the filter basket (outside a basket space of the filter basket) and, in particular, is positioned in a space that at least partially surrounds the filter basket. This allows the entire dirty fluid flow to be coupled into the filter basket, and a relatively dry (dirt-laden) air flow is extracted from outside the filter basket and, in particular, from the space surrounding the filter basket. This means that this space is in direct fluid communication with the outlet device. This results in an effective separation function, particularly for a liquid-laden dirty fluid.

[0073] In one embodiment, at least one sensor for determining the fill level of the container's receiving space is positioned on the basket holder. This results in a compact design. The existing basket holder is then also used as a sensor holder.

[0074] In one embodiment, the at least one sensor is arranged on a splash guard. This results in an effective and compact design.

[0075] It is particularly advantageous if a splash guard is installed on the basket holder. This allows the existing basket holder to be used effectively. The splash guard effectively prevents or even prevents liquid from splashing back into the container's receiving space. This also allows the separator-container device to function essentially independent of inclination.

[0076] In one embodiment, the anti-slosh device comprises at least one anti-slosh strip, and in particular two anti-slosh strips, which provide a seal between the basket holder and the container wall. This prevents sloshing outside a desired area of ​​liquid. Furthermore, effective flow guidance, in particular air flow guidance, is achieved. This, in turn, allows for an effective separator function.

[0077] In particular, at least one of the following is provided: the at least one splash guard is arranged on an outer side of a receiving wall of the basket holder; the at least one splash guard is oriented parallel or at an acute angle of at most 150° to a vertical axis of the receiving space of the container; at least one sensor is arranged on the at least one splash guard; the at least one splash guard extends beyond a receiving base of the basket holder in the direction of the container base; at least one electrical cable is guided in the at least one splash guard.

[0078] The at least one splash guard strip therefore has an effective function while being structurally simple.

[0079] It is furthermore advantageous if a first anti-splash strip and a second anti-splash strip are provided, which are spaced apart from one another, with at least one of the following: the first anti-splash strip and the second anti-splash strip are oriented at least approximately parallel to one another; at least one outlet opening of the basket holder is positioned between the first anti-splash strip and the second anti-splash strip; the first anti-splash strip and the second anti-splash strip delimit a space in the container, in which at least one outlet opening of the basket base and at least one passage opening to an outlet device for an air flow are located; the first anti-splash strip and the second anti-splash strip hold at least one anti-splash plate, which is positioned at a distance from a receiving base of the basket holder between the first anti-splash strip and the second anti-splash strip;an annular wall extends between the first anti-slosh strip and the second anti-slosh strip;

[0080] This results in a compact design. The anti-spill strips with the anti-spill function are used as holders. By defining a space within the container, which contains an outlet opening in the basket base and at least one opening leading to an outlet device for an air stream, effective flow guidance with an effective separator function can be achieved.

[0081] The ring wall also provides an anti-splash function and allows the formation of a drip tray.

[0082] In one embodiment, the anti-slosh device comprises at least one anti-slosh plate, which is assigned to at least one outlet opening of the basket holder. The anti-slosh plate effectively prevents or at least reduces the sloshing of liquid at the at least one outlet opening, even when the separator-container device is in a horizontal or approximately horizontal position, in which the vertical axis of the receiving space is oriented transversely to the direction of gravity.

[0083] It is advantageous if at least one of the following is provided: the at least one anti-slosh plate is positioned on the basket holder and rests on an inner side of the container wall; the at least one anti-slosh plate is spaced from the at least one outlet opening; the at least one anti-slosh plate extends in a transverse direction to a vertical axis of the receiving space of the container; the at least one anti-slosh plate rests on a container part wall, wherein the container part wall is closest to the at least one outlet opening in the region of the container wall, and a distance of an end of the at least one anti-slosh plate, which is spaced from an end of the at least one anti-slosh plate with which it rests on the container part wall, has a greater distance from this container part wall in a transverse direction to a vertical axis of the receiving space than the at least one outlet opening;the at least one anti-slosh plate is positioned at an acute angle to a vertical axis of the receiving space of the container, wherein in particular a distance of an end of the at least one anti-slosh plate, with which it rests against a partial wall of the container wall, from the at least one outlet opening and relative to a vertical axis of the receiving space is greater than a distance of an opposite end of the at least one anti-slosh plate from the at least one outlet opening; the acute angle lies in the range between 30° and 60° and in particular in the range between 35° and 55°, and in particular in the range between 40° and 50°.;

[0084] The at least one anti-splash plate covers the outlet opening at a distance from the outlet opening in relation to the vertical axis of the receiving space in order to effectively reduce the splashing of liquid into the outlet opening.

[0085] The angular orientation effectively prevents liquid from sloshing in. It is particularly advantageous if an annular wall is arranged on the basket holder facing the container bottom, particularly for guiding the liquid. The annular wall allows for effective dripping of liquid, particularly from at least one outlet opening of a basket holder receptacle. This, in turn, allows a substantially dry air stream (which may still contain fine dirt) to be supplied to the lid device. This allows for an effective separator function with respect to both coarse dirt and liquid.

[0086] In particular, the annular wall has an end face facing the container bottom, and the end face is assigned an enveloping plane, wherein the enveloping plane is oriented at an acute angle to a vertical axis of the container's receiving space. This provides an anti-splash function. It also provides an effective liquid drainage function. The annular wall forms a type of drip tray to effectively drain liquid and then collect it in the receiving space.

[0087] It has proven advantageous if the acute angle lies in a range between 30° and 60°, and especially in the range between 35° and 55°, and especially in the range between 40° and 50°. In one specific embodiment, the acute angle is 45°.

[0088] It is further advantageous if the distance between the envelope plane and a receiving base of the basket holder increases toward at least one outlet opening of the basket holder. This results in an effective liquid drainage function. In particular, effective dripping of liquid can be achieved near the at least one outlet opening.

[0089] To achieve effective fluid drainage and flow control, the annular wall is open toward the container bottom and toward the inside of one of the container's partial walls. The opening toward the inside of the container's partial wall allows fluid emerging from at least one outlet opening of a basket holder to be collected and directed. The opening toward the container bottom prevents accumulation, thus ensuring effective drainage.

[0090] In particular, the container has an area in the receiving space of the container toward which the annular wall is open, wherein at least one outlet opening of the basket holder is located in this area. This results in effective flow guidance, and an effective separation function can be achieved with regard to both coarse dirt and liquid. This, in turn, makes it possible to direct a substantially dry, dirt-laden air stream to the cover device, and, after filtering, to create an effective clean-side interface for a blower device of the cleaning machine on a clean side of the cover device.

[0091] At least one anti-splash plate is preferably positioned on the annular wall, particularly outside an interior space of the annular wall. The annular wall serves as a mount for the at least one anti-splash plate, resulting in a simple structural design. The at least one anti-splash plate ensures that contaminated liquid cannot enter the at least one outlet opening, particularly when the separator-container device is in a horizontal position.

[0092] It is advantageous if at least one anti-slosh plate has an angular orientation that is at least identical in sign to an envelope plane of the ring wall. This results in an effective anti-slosh effect.

[0093] In one embodiment, the separator-container device has an upper side facing away from the container bottom and on which an outlet device for connection to a blower device is arranged. An envelope plane is assigned to the upper side, and the envelope plane is oriented at an acute angle to a vertical axis of the container's receiving space. This allows the separator-container device to be easily aligned with a receptacle of the cleaning machine. A fluid-tight connection to the blower device can be easily achieved during insertion.

[0094] Furthermore, the object mentioned at the outset is achieved according to the invention in that the separator container device comprises: a container with a container bottom and a container wall, wherein a receiving space is formed between the container bottom and the container wall, and a lid device which is seated on the container at a distance from the container bottom, wherein a filter basket is positioned in the container, wherein a dirty fluid flow is completely introduced into the filter basket, wherein a collecting space for dirty fluid is arranged in the receiving space between the filter basket and the container bottom, and wherein a connection for extracting an air flow is in direct fluid-effective connection with a part of the receiving space outside the filter basket.

[0095] The solution according to the invention has the advantages already explained above. Further advantageous designs of the separator-container device according to the invention have also been explained above.

[0096] The entire (and particularly liquid-laden) dirty fluid flow is directed into the filter basket. Coarse dirt can be collected there. Dirty fluid can then be collected from the filter basket in the collection chamber (as part of the container's holding space) below the filter basket, between the filter basket and the container floor. A relatively dry (dirt-laden) air stream can be extracted from outside the filter basket (but still inside the container), and especially from a space around the filter basket.

[0097] This results in effective separation of coarse dirt, liquid, and air. It is advantageous if the part of the intake chamber that is in direct fluid connection to the airflow extraction surrounds the filter basket. This results in an effective separation function.

[0098] The object mentioned at the outset is further achieved according to the invention in the separator container device mentioned at the outset in that a basket holder for at least one filter basket is connected to the container and / or the lid device, that an annular wall is arranged on the basket holder pointing towards the container bottom, and that the annular wall is open towards the container bottom and is open towards an inner side of a container part wall.

[0099] The solution according to the invention has the advantages already explained above. Further advantageous designs of the separator-container device according to the invention have also been explained above.

[0100] Coarse dirt can be collected via the filter basket.

[0101] An effective separator function is achieved for coarse dirt and also for liquids. Liquid can be effectively drained (into a collection chamber), with a defined flow of liquid along the annular wall to fill the collection container.

[0102] The filter basket allows for smoothing of the flow. This causes contaminated liquid to drip down to the bottom of the tank. The ring wall, in turn, improves this drainage of liquid; it provides a kind of drip tray.

[0103] This allows the filter basket to be flushed with liquid. Furthermore, a vacuum is applied to the filter basket. This dries coarse dirt. Fine dirt can bind with liquid and can then be partially transported into the container's holding space. Furthermore, the constant flushing of the filter basket increases the time it takes for the filter basket to become clogged.

[0104] According to the invention, a cleaning machine of the type mentioned at the outset is provided, which comprises a separator-container device according to the invention, which is in particular detachably fluidically connected to the blower device.

[0105] The cleaning machine according to the invention has the advantages already explained in connection with the separator container device according to the invention.

[0106] A corresponding cleaning machine can, for example, be a floor cleaning machine for dry or liquid cleaning of a floor, for example in the form of a mop. The cleaning machine can also be a wet / dry vacuum cleaner, for example. The cleaning machine has a suction function via the blower device.

[0107] In particular, when the separator container device is positioned on the cleaning machine, the inlet device on the cover device faces away from an outer contour area of ​​the cleaning machine. This results in an effective connection.

[0108] Furthermore, according to the invention, a method for operating a separator-container device is provided, wherein the separator-container device has a container with a container bottom and a container wall, wherein a receiving space is formed between the container bottom and the container wall, in which a filter basket is positioned in the container, into which a complete dirty fluid flow is introduced, wherein dirty fluid collects in a collecting space of the receiving space, which is located below the filter basket between the filter basket and the container bottom, and in which an air flow is discharged, wherein the air flow is discharged from a partial area of ​​the receiving space outside the filter basket.

[0109] This creates an effective separation function, separating coarse dirt, which is collected in the filter basket, from contaminated liquid. The contaminated liquid is collected in the collection chamber below the filter basket. Furthermore, a relatively dry, ventilated air stream can be provided, which is then discharged from the section of the collection chamber outside the filter basket.

[0110] Further advantages of the method according to the invention have already been explained in connection with a separator-container device according to the invention. Furthermore, further design details of the corresponding method have been explained in connection with the device.

[0111] In particular, it is provided that the portion of the receiving space from which air is discharged at least partially surrounds the filter basket and is located, in particular, outside a basket space of the filter basket. For example, it is provided that contaminated fluid is coupled into the filter basket at least approximately centrally and is thereby coupled into a basket space. The air flow is then discharged decentrally in a portion of the receiving space outside the filter basket.

[0112] The following description of preferred embodiments, taken in conjunction with the drawings, serves to further explain the invention. They show:

[0125] One embodiment of a cleaning machine according to the invention is a floor cleaning machine 10 (Figure 1). The floor cleaning machine 10 serves to clean a floor 12. The floor 12 is, in particular, a hard floor. The floor cleaning machine 10 can also be designed so that it can be used to clean both hard floors and textile floors.

[0126] The floor cleaning machine 10 comprises a cleaning head 14 (floor head). During a cleaning operation, the floor cleaning machine 10 is positioned above the cleaning head 14 on the floor 12 to be cleaned.

[0127] (At least) one cleaning roller 16 is arranged on the cleaning head 14. The cleaning roller 16 is driven to rotate about a rotational axis 18. A corresponding drive is located in particular on the cleaning head 14.

[0128] The cleaning head 14 has further support means 20 for supporting the cleaning head 14 on the floor 12 by means of a support plane 22. The support plane 22 coincides, in particular, with a floor plane of the floor 12.

[0129] The further support means 20 can be one or more rollers, skids or (at least) one further cleaning roller.

[0130] In one embodiment, the at least one cleaning roller 16 is provided with a textile trim and in particular microfiber trim.

[0131] A support rod device 26 is pivotally connected to the cleaning head 14 via a joint device 24. The support rod device 26 serves to guide the floor cleaning machine 10 over the floor 12 to be cleaned by an operator who stands on the floor 12. In particular, it is provided that the operator stands behind the floor cleaning machine 10, and accordingly, the cleaning head 14 has a front end 28 and a rear end 30. During normal cleaning operation, the floor cleaning machine 10 is guided in a forward direction 32, which is a direction from the rear end 30 to the front end 28. For normal operation, the operator stands behind the rear end 30 on the floor 12, facing away from the front end 28.

[0132] The joint device 24 has a pivot axis 34. The pivot axis 34 is in particular parallel to the rotation axis 18 of the cleaning roller 16.

[0133] In the graphic representation according to Figure 1, the pivot axis 34 is perpendicular to the plane of the drawing.

[0134] Due to the pivotability of the joint device 24 about the pivot axis 34, a pivot position of the support rod device 26 relative to the floor 12 can be varied. This is indicated in Figure 1 by the arrow 36.

[0135] This pivotability about the pivot axis 34 on the joint device 24 allows the holding rod device 26 to be brought into a parking position (see Figure 1), in which it is oriented at least approximately perpendicular to the cleaning head 14 or to the floor 12.

[0136] When the floor cleaning machine 10 is operated, the support rod device 26 is moved from the parked position. The pivoting ability about the pivot axis 34 on the joint device 24 allows the operator to adjust it to their height.

[0137] Furthermore, the aforementioned pivoting capability allows an operator to, for example, drive under furniture or the like; they can correspondingly reduce the overall height of the floor cleaning machine 10 between the installation plane 22 and a proximal end 38 of the support rod device 26. A pivot angle ß is indicated in Figure 1. The support rod device 26 is generally pivotable between ß approximately 90° (Figure 1) to ß close to 0° (parallel alignment to the floor 12). The corresponding pivot angle ß can also be limited, for example, to 5° or 10°.

[0138] A handle 40 for an operator is located at the proximal end 38 of the support rod assembly 26. In one embodiment, the handle 40 is designed as a circumferential bow handle.

[0139] The cleaning head 14 is articulated at a distal end 42 of the holding rod device 26 via the joint device 24.

[0140] A housing device 44 is positioned on the support rod device 26 between the proximal end 38 and the distal end 42.

[0141] A blower device 46 is located in the housing device 44. The blower device 46 comprises a fan for generating a vacuum flow (suction flow). It further comprises a motor, in particular an electric motor, for driving at least one fan impeller of the fan.

[0142] A connection 48 is located on the machine side of the housing assembly 44, through which the suction flow can be tapped. Connection 48 is located on the clean side.

[0143] A further connection 50 is arranged on the housing device 44, through which the suction flow generated by the blower device 46 can be directed to the cleaning head 14. Via the further connection 50, the cleaning head 14 can be subjected to the corresponding vacuum flow in order to remove a dirty fluid. In particular, it is provided that the floor cleaning machine 10 has a discharge device 52, via which the suction flow can act on the cleaning head 14.

[0144] In one embodiment, the discharge device 52 comprises a nozzle device 54, which points toward the cleaning roller 16. This allows the cleaning roller 16 to be directly exposed to the suction flow or the dirty fluid to be directly discharged from the cleaning roller 16.

[0145] The further connection 50 is located on a dirty side of the floor cleaning machine 10.

[0146] The housing device 44 has a receptacle 56 for a separator-container device 58. The separator-container device 58 has a corresponding connection 60 as an inlet and a connection 62 as an outlet. Dirty fluid can be coupled into the separator-container device 58 via the connection 60, which is connected to the further connection 50. An air stream can be coupled out via the connection 62, which is coupled to the connection 48. The direct connection to the blower device 46 is established via the connection 62. The direct connection to the nozzle device 54 is established via the connection 60.

[0147] The separator container device 58 serves to receive and collect dirt. Furthermore, it has a separator function to separate an air stream from dirt in order to establish the fluid connection with the blower device 46 at the connection 62.

[0148] In principle, the separator-container device 58 is also designed such that it can be supplied (via connection 60) with a dry dirty fluid stream, or with a dirty fluid stream containing a liquid. In the case of a dirty fluid stream containing a liquid, the separator-container device 58 also has the task of effecting liquid separation. The separator-container device 58 according to the invention is advantageously used in conjunction with a cleaning machine 10 that performs wet cleaning, so that the dirty fluid stream contains a liquid. The separator-container device 58 is a separator-container device 58 for a wet cleaning machine, whereby dry operation is also possible in principle.

[0149] For the purposes of this application, a contaminated fluid is understood to be a flowable, contaminated medium. As mentioned above, the contaminated fluid can be dry and contain, for example, coarse and fine dirt particles. It can also be liquid and contain, for example, water with, for example, coarse and fine dirt particles.

[0150] The separator container device 58 is removably mounted on the housing device 44.

[0151] In one embodiment, the receptacle 56 has a hollow cuboid shape, at least approximately or with respect to an enveloping surface.

[0152] The housing device 44 has a side 64 facing away from a support rod 66 of the support rod device 26. The receptacle 56 is adjacent to the side 64 and forms a recess relative to the side 64.

[0153] When the separator-container device 58 is positioned on the holding rod device 26 and the housing device 44, a corresponding side 68 of the separator-container device 58, which faces away from the holding rod 66, is at least approximately aligned with the side 64 of the housing device 44 or is slightly recessed relative to this side 64. A handle 70 for holding the separator-container device 58 is then positioned on the side 68 in order to be able to remove the separator-container device 58 from the holding rod device 26 via the side 64 of the housing device 44 or to be able to insert it there.

[0154] In particular, the handle 70 projects beyond an envelope plane of the side 64.

[0155] The connections 48 and 50 are positioned at a height distance from each other on the receptacle 56. The connection 50 is located closer to the cleaning head 14 or to the distal end 42 of the holding rod device 26.

[0156] In one embodiment, it is provided that a wet cleaning of the floor 12 can be carried out via the floor cleaning machine 10.

[0157] A tank 72 for a cleaning fluid is located on the housing device 44, facing away from the receptacle 56. The tank 72 is intended, in particular, to hold fresh water, to which a surfactant cleaning agent may optionally be added.

[0158] A line system leads from the tank 72 to the cleaning head 14. The floor 12 to be cleaned and / or the cleaning roller 16 can be supplied with cleaning fluid from the tank 72.

[0159] In particular, a scraper is provided, which is assigned to the cleaning roller 16. The scraper can be used to scrape dirt fluid from the textile material of the cleaning roller 16. The dirt fluid can then be sucked away at the nozzle device 54 via the blower device 46.

[0160] Regarding the basic operation of such a floor cleaning machine, reference is made to WO 2015 / 086083 A1 as an example. Cleaning fluid from the tank 72 can be fed to the cleaning head 14 by gravity or, for example, by a pump.

[0161] In one embodiment of a floor cleaning machine 10, a battery device 74 is provided for supplying electrical consumers with electrical energy. In principle, mains operation can also be provided.

[0162] In the floor cleaning machine 10 according to Figure 1, the side 64 of the housing assembly 44 faces the rear end 30 of the cleaning head 14. The tank 72 faces the front end 28.

[0163] This means that when the holding rod device 26 is pivoted about the pivot axis 34 while reducing the angle ß, the separator container device 58 is pivoted towards the floor 12 and the separator container device 58 lies between the holding rod 66 and the floor 12.

[0164] It is fundamentally possible for the joint device 24 to have, in addition to the pivot axis 34, at least one further pivot axis for, for example, a relative rotatability of the holding rod device 26 to the cleaning head 14, in particular with a rotation axis transverse to the pivot axis 34.

[0165] An embodiment of a separator-container device 58 according to the invention, which is shown in Figures 2 to 10, comprises as essential components a container 76, a lid device 78, a first filter device 80, which is seated on the lid device 78, and a filter holder 82 for a second filter device 84. The second filter device 84 is a filter basket, and accordingly, the filter holder 82 is a basket holder. The container 76 has a container base 86, on which a container wall 88 is seated circumferentially. A receiving space 90 is formed between the container wall 88 and the container base 86.

[0166] The receiving space 90 has a height axis 92. The height axis 92 lies transversely and in particular perpendicular to the container bottom 86.

[0167] When the separator container device 58 is positioned on the floor cleaning machine 10, the height axis 92 is oriented at least approximately parallel to a longitudinal axis of the holding rod 66.

[0168] The lid device 78 closes the receiving space 90 at a distance from the container bottom 66 on an upper side.

[0169] The receiving space 90 has a volume that is typically in the range between 0.5 and 1.5 for the application of the floor cleaning machine 10. The receiving volume of the receiving space 90 for dirt fluid is smaller than the volume of the receiving space 90 due to the basket holder 82.

[0170] The container bottom 86 is closed and connection-free. It is particularly plate-shaped.

[0171] In one embodiment, the container base 86 has a raised portion 94 projecting into the receiving space 90, wherein the raised portion 94 has an outward opening 96. An element of a fixing device of the floor cleaning machine 10, which is arranged on the receptacle 56, can be inserted into the opening 96 to achieve a positive locking fixation in transverse directions transverse to the vertical axis 92 on the floor cleaning machine 10.

[0172] The container bottom 86 is formed, in particular, by a plate. The container wall 88 is connected to the container bottom 86 and, in particular, is integrally connected. It protrudes beyond the container bottom 86 in a direction parallel to the vertical axis 92.

[0173] In one embodiment, the container wall 88 has a substantially flat side 98 (see, for example, Figure 5). Opposite the flat side 98 is the side 64. The handle 70 is arranged on the side 64. The handle 70 is positioned in particular in the region of an end face 100 of the container 76, with the end face 100 facing away from the container bottom 86.

[0174] In particular, the container wall 88 is curved on the side 64 with a corresponding transition to the flat side 98.

[0175] The receiving space 90 includes a collecting space 101 (see Figures 1 to 9) for contaminated liquid. This collecting space 101 is a portion of the receiving space 90 between the container bottom 86 and the filter basket 84. Contaminated liquid exiting the filter basket 84 is collected in the collecting space 101 below the filter basket 84 in the container 76.

[0176] A flow tube 102 is arranged on the container 76. The flow tube 102 is connected to the flat side 98 of the container wall 88 and extends parallel to the vertical axis 92. The flow tube 102 is positioned outside the receiving space 90. It is offset from the container bottom 86.

[0177] The flow tube 102 has an inlet 104 and an outlet 106. In the illustrated embodiment, the inlet 104 is located at the container bottom 86 relative to the vertical axis 92, i.e., at the same height as the container bottom 86. It is also possible, in principle, for the inlet 104 to be offset (relative to the vertical axis 92) from the container bottom 86.

[0178] The outlet 106 of the flow tube 102 is located on the end face 100. The outlet 106 is in particular diametrically opposite the handle 70.

[0179] The flow pipe 102 is designed, in particular, as a riser pipe. When the separator-container device 58 is attached to the floor cleaning machine 10, the dirty fluid flowing in the flow pipe 102 rises against the direction of gravity g (see Figure 1) from the inlet 104 to the outlet 106. The corresponding conveyance is effected by the blower device 46.

[0180] If the angle ß according to Figure 1 is 90° or even greater than 90°, then the flow pipe 102 does not act as a riser pipe.

[0181] The further connection 50 is formed at the inlet 104. Via this connection, the container 76 of the separator-container device 58 can be fluidly connected to the flow pipe 102 with the connection 60 of the cleaning machine 10 (and is connected as shown in Figure 1). At the inlet 104 of the flow pipe 102, a dirty fluid flow is transferred from the cleaning machine 10 to the separator-container device 58.

[0182] In particular, it is provided that a sealing device for fluid-effective coupling is present at the inlet 104 and / or the connection 60.

[0183] Furthermore, it is particularly provided that the flow tube 102 can be plugged onto the connector 60 at the inlet 104. Accordingly, the connector 60 comprises a nozzle that projects toward the receptacle 56. An outer contour of the container 76 is adapted to the housing 44 of the floor cleaning machine 10. In particular, the wall region of the container wall 88 outside the flat side 98 follows an outer contour of the housing 44.

[0184] Overall, the container wall 88 is adapted to the receptacle 56 in order to enable secure fixing of the separator container device 58 to the floor cleaning machine 10.

[0185] The basket holder 82 has a flange 108. The flange 108 can be placed on a ledge inside the container 76 near the end face 100, thereby allowing the basket holder 82 to be held to the end face 100 of the container 76.

[0186] The basket holder 92 can be removed as a whole from the container 76. Figure 2 shows a state in which the basket holder 92 has just been removed.

[0187] The further design of the basket holder 82 is described below.

[0188] The lid device 78 closes the receiving space 90 at the front side 100. The lid device 78 is removable as a whole from the container 76. Figure 2 shows a state in which the lid device 78 is removed from the container 76.

[0189] The lid assembly 78 has a bottom side 112 and a top side 114. A nozzle 116 is arranged on the bottom side 112. The nozzle 116 serves for insertion into an opening 110. The opening 110 is located, in particular, on the container 76 above the flange 108. When the basket holder 82 is seated on the container 76, the lid assembly 78 is placed on the basket holder 82.

[0190] In particular, a sealing device is arranged on the nozzle 116 (and / or the opening 110). This ensures a fluid-tight seal between the nozzle 116 and the container 76. A further nozzle 118, which is associated with the flow tube 102, is arranged on the underside 112. When the lid device 78 properly closes the container 76, the nozzle 118 is immersed in the flow tube 102 at the outlet 106. This establishes a flow connection to the lid device 78.

[0191] The cover assembly 78 has an inlet assembly 120 for dirty fluid. Dirty fluid is coupled from the flow tube 102 into the cover assembly 78 via the inlet assembly 120. This inlet assembly 120 is formed at or by the nozzle 118.

[0192] The cover device 78 comprises a housing 122. The nozzle 116 and the nozzle 118 are located on the housing 122.

[0193] A sealing device is also provided on the nozzle 118 and / or the outlet 106 of the flow pipe 102.

[0194] A deflection tube 124 is positioned in the housing 122 of the cover assembly 78. The deflection tube 124 extends from the nozzle 118 to an orifice 126. The orifice 126 points into the opening 110 of the flange 108 or is arranged at the opening 110.

[0195] The deflection pipe 124 is fluidly connected on the input side to the inlet device 120 (with the nozzle 118). In particular, the nozzle 118 is arranged on the deflection pipe 124.

[0196] At the mouth 126, the deflection tube 124 has an outlet 128. When the container 76 is properly closed with the lid device 78, the outlet 128 (the mouth 126) faces the container bottom 86. In particular, the outlet 128 has a mouth normal 130, which is parallel to the vertical axis 92 of the receiving space 90 or parallel to a normal on the inside of the container bottom 86.

[0197] Accordingly, the mouth normal 130 at the outlet 128 is oriented transversely and in particular perpendicularly to an inner side of the container bottom 86.

[0198] Furthermore, the mouth normal 130 is oriented parallel to an inner side of the container wall 88.

[0199] The flow tube 102 has a longitudinal axis 132, which is parallel to the vertical axis 92 of the receiving space 90. The outlet normal 130 is parallel to the longitudinal axis 132 of the flow tube 102.

[0200] Via the flow tube 102, dirty fluid is coupled into the cover assembly 78 at the inlet assembly 120 on the deflection tube 124. The deflection tube 124 ensures a flow deflection. Dirty fluid flows in a main flow direction parallel to the longitudinal axis 132 through the flow tube 102 and from the inlet 104 to the outlet 106. The deflection tube 124 deflects the flow in an opposite direction, in particular to allow filling of the container 76 via the cover assembly 78.

[0201] The flow of dirty fluid at the mouth 126 as it exits the deflection pipe 124 and enters the opening 110 on the flange 108 is directed toward the container bottom 86.

[0202] A receptacle 134 is formed on the cover device 78, which is open toward the top side 114. The receptacle 134 forms a filter holder for the first filter device 80. The first filter device 80 is, in particular, removably positioned on the receptacle 134 and thus on the cover device 78. The first filter device 80 is or comprises a fine dust filter or motor protection filter.

[0203] The separator-container device 58 has an outlet device 136, which includes the connection 48 and serves for connection to the blower device 46. The outlet device 136 is an outlet for an air flow or an inlet for a suction flow.

[0204] The first filter device 80 has a clean side 138 at the outlet device 136. It has a dirty side 140 which faces an interior of the housing 122 of the cover device 78.

[0205] The receptacle 134 and thus the first filter device 80 is positioned above the deflection tube 124, in particular with respect to the height axis 92.

[0206] One or more channels 142 are formed in the housing 122, which provide a fluid-effective connection with the receiving space 90 and the first filter device 80 in the cover device 78.

[0207] The separator-container device 58 also has a separation function, as explained in more detail below. Coarse dirt, in particular, can be separated from the dirty fluid stream at the second filter device 84. Furthermore, any contaminated liquid can be separated there and collected in the receiving chamber 90.

[0208] Air can be guided as an air stream to and through the first filter device 80 via the channel(s) 142, which are open toward the basket holder 82. This air stream may contain fine dirt particles. The first filter device 80 is accordingly designed to filter out these fine particles in order to protect the motor of the blower device 46. In particular, the first filter device 80 comprises a flat pleated filter (see Figure 2).

[0209] The cover device 78 forms, in a sense, the fluid communication center of the separator-container device 58. After flowing through the flow tube 102, the dirty fluid flow is coupled into the cover device 78 at the inlet device 120 and flows into the container 76 at the outlet 128. A possibly contaminated air flow flows through the cover device 78 at the channel(s) 142 and is filtered and discharged from the separator-container device 58 at the outlet device 136. The cover device 78 is thus the communication center with the floor cleaning machine 10. In the exemplary embodiment of the separator-container device 58, the inlet device 120 is, in a sense, extended by the flow tube 102, and the direct coupling to the floor cleaning machine 10 takes place via the flow tube 102 with its inlet 104.

[0210] The upper side 114 of the cover device 78 has an enveloping plane 144 which lies at an acute angle 146 to the height axis 92. This acute angle 146 is in particular on the order of 45°.

[0211] The upper side 114 is designed such that the envelope plane 144 is inclined toward the flow tube 102. In an extension of the side 68 with the handle 70, the envelope plane 144 is at a greater distance from the container bottom 86 than at an extension of the flat side 98.

[0212] Due to the enveloping plane 144 and the acute angle 146, the separator-container device 58 can be inserted into the receptacle 56 of the floor cleaning machine 10, whereby the outlet device 136 can then be pressed against the connection 48, achieving a tight connection. As described above, the flow pipe 102 lies outside the receiving space 90 of the container 76. The nozzle 118 of the cover device 78 and thus also the inlet device 120 on the cover device 78 are then located, so to speak, adjacent to the container 76. In a transverse direction 149 to the vertical axis 92, the inlet device 120 is offset from the container bottom 86, from the container wall 88, and from the receiving space 90.

[0213] A projection of the inlet device 120 (of the nozzle 118) in the vertical axis 92 onto the container bottom 86 lies outside the container bottom 86; the inlet 104 is also located next to the container bottom 86.

[0214] The filter basket 84, as the second filter device, has a basket base 148 (see, for example, Figure 8) and a basket wall 150. The basket base 148 has, for example, at least approximately the shape of a circular disk. The basket wall 150 is firmly connected to the basket base 148, in particular as a single piece.

[0215] A basket chamber 152 is formed between the basket wall 150 and the basket bottom 148. The basket chamber 152 is a receiving space for dirt particles.

[0216] The filter basket 84 has a support structure 154 with through-openings on the basket wall 150 and, if applicable, also on the basket base 148. A mesh fabric, particularly made of a metallic material, is attached to the support structure 154. The mesh fabric has a mesh size in the range between 50 μm and 300 μm. This mesh size defines the filtering effect of the filter basket 84.

[0217] The mesh fabric is arranged on the basket wall 150. The basket base 148 can be closed or can also have a support structure like the support structure 154 and be provided with a mesh fabric. At least one spacer 156 is arranged on the basket base 148 on an outer side (facing away from the basket space 152).

[0218] In one embodiment, a plurality of spaced webs are provided as spacers, with a passage opening located between adjacent webs.

[0219] The filter basket 84 can be supported on the basket holder 82 via the spacer 156, as will be explained in more detail below.

[0220] The basket holder 82, as mentioned above, includes the flange 108. The flange 108 is a type of intermediate cover on the container 76. The flange 108 serves to fix the filter holder 82 to the container 76. The flange 108 also holds a receptacle 160 for the filter basket 84 at a holding area 158.

[0221] Outside the holding area 158, a first through-opening 162a and, spaced therefrom, a second through-opening 162b are arranged on the flange 108. Between the first through-opening 162a and the second through-opening 162b, the flange 108 has a free area 164. The nozzle 118 extends through the free area 164 (when the basket holder 82 and the lid assembly 78 are attached to the container 76).

[0222] The passage openings 162a, 162b are fluidly connected to the channel or channels 142 in the cover device 78. A (possibly contaminated) air stream can flow from the receiving space 90 through the passage openings 162a, 162b into the cover device 78, or a suction stream generated by the blower device 46 can be passed through the passage openings 162a, 162b and then also passed through the filter basket 84.

[0223] The passage openings 162a, 162b open into a space 159, which is a

[0224] Part of the receiving space 90 and is located above the collecting space 101. The space 159 (see also Figure 9) is located outside the filter basket 84 and also the filter holder 82. The air flow is extracted outside the basket space 152.

[0225] In particular, the space 159 surrounds the basket wall 150 at least between the anti-slosh strips 182, 184.

[0226] In particular, it is provided that the coupling of contaminated fluid into the basket chamber 152 via the opening 126 is at least approximately centralized. The discharge of the air flow from the receiving chamber 90 to the chamber 159 is then decentralized.

[0227] The receptacle 160, which is formed on the holding portion 158 of the flange 108 of the basket holder 82, comprises a receiving base 166 and a receiving wall 168. The receiving wall 168 is fixedly connected to the flange 108 at the holding portion 158. The receiving base 166 is spaced from the flange 108.

[0228] The receiving base 166 is closed.

[0229] Between the receiving base 166 and the receiving wall 168, the receptacle 160 of the basket holder 82 has a receiving space 170. The receiving space 170 of the basket holder 82 is open toward the flange 108; the flange 108 has an opening 172. This opening 172, in turn, faces the lid device 78.

[0230] The filter basket 84 is positioned in the receiving space 170, standing on the receiving base 166 and being spaced from an inner side of the receiving base 166 by the spacer(s) 156 of the basket base 148.

[0231] The filter basket 84 can be removed or inserted through the opening 172 (when the cover assembly 78 is removed). The receptacle 160 is provided with a window 174 into the receiving space 90 of the container 76. In particular, exactly one window 174 is provided. The window 174 forms an outlet opening 176 for a stream of dirty fluid that has flowed through the filter basket 84.

[0232] The outlet opening 176 (the window 174) is arranged on the receiving wall 168 and extends in particular to the receiving base 166.

[0233] Relative to the vertical axis 92 of the receiving space 90 of the container 76, the receiving space 170 of the basket holder 82 extends in a vertical direction. The window 174 does not occupy the entire height of the receiving space 170, but rather, for example, at most 50% and in particular at most 40% or at most 30% of the height of the receiving space 170 in this vertical axis 92.

[0234] The opening 176 extends in a circumferential direction relative to the vertical axis 92 on the receiving wall 168. It extends in a sector, with the outlet opening 176, in particular, extending over an angular range of at least 10° and in particular 15°. Furthermore, it is advantageous if the outlet opening 176 (the window 174) extends over an angular range of at most 40° and in particular at most 30°.

[0235] The outlet opening 176 points into a region 178 of the receiving space 90 of the container 76 (when the basket holder 82 is attached to the container 76), which faces the flow tube 102. The region 178 faces away from the handle 70.

[0236] The passage openings 162a, 162b open into the region 178, i.e., a fluid-effective connection exists between the window 174 and the passage openings 162a, 162b through the region 178. This also creates a fluid-effective connection between the window 174 and the outlet device 136 of the lid device 78 (when the lid device 78 is positioned on the container 76 with the basket holder 82).

[0237] A splash protection device 180 is arranged on the basket holder 82.

[0238] A first anti-splash strip 182 and a second anti-splash strip 184 are spaced apart from one another on the basket holder 82 and on an outer side of the receiving wall 168. The anti-splash strips 182, 184 are aligned parallel to the vertical axis 92 of the receiving space 90 (when the basket holder 82 is seated on the container 76).

[0239] They each extend from the flange 108 and are in particular connected thereto to a lower end 186. The lower end 186 faces the container bottom 86.

[0240] The splash guards 182, 184 extend with an area 188 beyond the receiving base 166, i.e. the length of a splash guard 182, 184 is greater than a height of the receiving space 170 in the height axis 92.

[0241] When the filter holder (basket holder) 82 is positioned on the container 76, the anti-splash strips 182, 184 each rest on a partial area 190 (see, for example, Figures 6 and 7) on an inner side of the container wall 88 and ensure a fluid-tight and, in particular, liquid-tight seal.

[0242] The area 178 lies between the first splash guard 182 and the second splash guard 184 (when the basket holder 82 is attached to the container 76). The first splash guard 182 and the second splash guard 184 seal the area 178. The window 174 is located between the first splash guard 182 and the second splash guard 184. In one embodiment, a sensor 192 is arranged on the first splash guard 182 and / or the second splash guard 184, and is arranged in particular in the area of ​​the lower end 186.

[0243] The sensor 192 is designed in particular as a fill level sensor, via which the fill level (in particular of liquid) in the container 76 and thereby in the receiving space 90 of the container 76 can be determined.

[0244] In particular, an electrical cable is then guided on the corresponding anti-splash strip 182, 184, via which sensor data in particular can be derived.

[0245] An annular wall 194 is arranged on the receiving base 166, facing away from the receptacle 160 and pointing in the direction of the container base 86.

[0246] The annular wall 194 has a convexly curved shape relative to the vertical axis 92. It has, for example, the shape of a circular ring. It surrounds an interior space 196. The annular wall 194 defines an opening 198 toward the container bottom 86 (when the basket holder 82 is seated on the container 76), so that the interior space 196 is open to the container bottom 86 via the opening 198.

[0247] The annular wall 194 is not closed, but has a further opening 200 parallel to the height axis 92; the opening 198 is transverse and in particular perpendicular to the height axis 92.

[0248] The further opening 200 leads into the area 178 of the receiving space 90 of the container 76.

[0249] The opening 198 extends from an outer side of the receiving base 166 in a circumferential direction. It is particularly symmetrical to the window 174, starting directly below the window 174 and relative to a center plane 202 in which the height axis 92 lies. The annular wall 194 has an end face 204 facing the container base 86 and facing away from the receiving base 166 of the receptacle 160 of the basket holder 82. The end face 204 has an enveloping plane 206 (for example, Figures 4 and 9). The enveloping plane 206 is oriented at an acute angle α (see Figure 3) to the receiving base 166. Accordingly, the enveloping plane 206 is oriented at an acute opposite angle to the height axis 92 (when the basket holder 82 is seated on the container 76).

[0250] The acute angle a is in the range between 30° and 60° and in particular at approximately 45°.

[0251] The envelope plane 206 is oriented such that it has a greater distance from the receiving base 166 in the region of the further opening 200 than in an opposite region 208. In the region 208, which is closer to the handle 70 than to the flow tube 102 with respect to the transverse direction 149, the annular wall 194 still has a partial region that extends over the receiving base 166 to the container base 86. The annular wall 194 does not taper to "zero" in this region 208.

[0252] Accordingly, the envelope plane 206 at the further opening 200 is closer to the container bottom 86 than at the region 208.

[0253] An angular range 210 (see Figure 7) in which the annular wall 194 extends in the circumferential direction is in particular at least 180° and preferably at least 190° and preferably at least 200°. In particular, due to the further opening 200, the angular range 210 is less than 300° and in particular less than 270° and in particular less than 230°. In one embodiment, the further opening 200, which defines a window of the annular wall 194 in the region 178, is set back from the window 174 of the receptacle 160 with respect to the transverse direction 149.

[0254] The annular wall 194 forms a drip system for the targeted drainage of, in particular, (dirty) liquid within the container 76. It also forms a splash guard.

[0255] A spill protection plate 212 is also arranged on the basket holder 82. It is positioned between the first spill protection strip 182 and the second spill protection strip 184 and is held by the latter at a distance from the receiving base 166. The spill protection plate 212 is associated with the outlet opening 176 (with the window 174) and positioned at a distance from it. It sits at the further opening 200 and then points away from the annular wall 194.

[0256] When the basket holder 82 is positioned on the container 76, the anti-slosh plate 212 rests with one end 214 (see Figure 2) against a container part wall 216 and ensures a seal there.

[0257] The anti-slosh plate 212 is oriented at least with respect to a top side at an acute angle 218 (see Figure 3) to the receiving base 166. It is oriented at this acute angle 218 to the height axis 92.

[0258] The acute angle 218 is in particular an opposite angle to the angle a and is, for example, of the order of 45°.

[0259] At end 214, the anti-slosh plate 212 is farther away from the receiving base 166 than at an opposite end. Accordingly, the anti-slosh plate 212 is closer to the container base 86 at end 214 than at the opposite end. The anti-slosh plate 212 extends from the annular wall 194 at the further opening 200 to the container wall 88 when the basket holder 82 is positioned on the container 76. The window 174 is covered relative to the vertical axis 92.

[0260] When positioning the separator container device 58 in which the height axis 92 is rotated relative to the direction of gravity, which is achieved by pivoting the holding rod device 26 by the angle ß, the anti-slosh plate 212 prevents liquid received in the receiving space 90 from sloshing into the window 174 up to a certain filling level.

[0261] It is also possible to provide a plurality of anti-slosh plates 212, which are then in particular spaced parallel to one another.

[0262] The basket holder 82 is detachably and removably positioned on the container 76.

[0263] The filter basket 84 is received in the receptacle 160. During operation of the floor cleaning machine 10 with the separator-container device 58, the cover device 78 is seated on the container 76. It is positioned on the basket holder 82 and in particular on the flange 108 with respect to the vertical axis 90.

[0264] The outlet 128 of the deflection pipe 124 is aligned with the basket space 152 and in particular is aligned centrally (in the middle).

[0265] A dirty fluid flow, which is coupled in by means of the flow pipe 102, flows through the cover device 78 with the deflection pipe 124, and this dirty fluid flow is coupled into the filter basket 84 via the cover device 78.

[0266] To empty the container 76, particularly of (contaminated) liquid, the lid assembly 78 is removed from the container 76. The through-openings 162a, 162b on the flange 108 are arranged such that the basket holder 82 does not need to be removed to empty the receiving space 90 of the container 76, particularly of contaminated liquid. Contaminated liquid, particularly, can be emptied through the through-openings 162a, 162b when the separator-container device 58 is removed from the floor cleaning machine 10 by tilting the container 76 with the lid assembly 78 removed.

[0267] The basket holder 82 can also be completely removed for improved emptying or cleaning of the container 76.

[0268] The separator container device 58 functions as follows (see in particular Figures 4 and 10):

[0269] The suction flow of the blower device 46 is coupled into the separator container device 58 at the outlet device 136 on the cover device 78 and flows through it.

[0270] Sucked-in dirty fluid is transferred from the floor cleaning machine 10 to the flow tube 102 at the inlet 104 in a dirty fluid stream 220. With a main flow direction parallel to the vertical axis 92, the dirty fluid flows through the flow tube 102 and is coupled into the cover device 78 at the inlet device 120. The dirty fluid stream is deflected in the deflection tube 124 and then flows into the filter basket 84 at the outlet 128. The filter basket 84 is seated on the basket holder 82 in the receptacle 160.

[0271] Due to the mesh on the filter basket 84, coarse dirt with a particle size larger than the mesh size cannot flow through the filter basket 84 and accumulates in the filter basket 84. This is indicated in Figure 4 by reference numeral 222. A dirty fluid stream (with filtered-out coarse dirt) flows through the filter basket 84. The corresponding air stream then contains only finer dirt particles, which are allowed to pass through the mesh. If the dirty fluid stream 220 contains liquid, it also contains liquid.

[0272] Filtering at the second filter device 84 (the filter basket 84) creates a dirty fluid stream 224, which may still contain liquid. It splits into a stream 226, which flows through the passage openings 162a, 162b and the channel(s) 142 to the first filter device 80 and flows through them. This stream 226 is dry and contains fine dirt particles that were passed through the second filter device 84. The first filter device 80 then provides fine dust filtration to protect the blower motor.

[0273] The stream 226 is dry compared to a stream 228, which is guided through the window 174 along the annular wall 194 into the receiving space 90 of the container 76. The annular wall 194 also functions as a type of drip tray for the targeted guidance of, in particular, a liquid-laden dirty fluid stream.

[0274] Stream 226, referred to above as dry, may still contain small amounts of liquid, but these amounts are considerably smaller than in stream 228.

[0275] The stream 226 is directed in the region 178 of the container 76 toward the lid device 78, and the stream 228 is directed into the receiving space 90.

[0276] This also achieves a separator function. The second filter device 84 separates coarse dirt. Furthermore, liquid (which may be contaminated) is separated, which then flows down the annular wall 194 into the receiving chamber 90. A comparatively dry stream 226 is fed to the first filter device 80.

[0277] The filter holder 82 is arranged such that the filter basket 84 is immersed in the receiving space 90 of the container 76.

[0278] The cover device 78 is a type of fluid communication center of the separator-container device 58. Through it, the original dirty fluid flow is completely coupled into the filter basket 84, and it also ensures the coupling of a purified air flow at the first filter device 80, i.e., for the direct connection to the blower device 46.

[0279] The flow tube 102 is arranged outside the receiving space 90. This creates a large, unobstructed volume for receiving, in particular, liquid-laden contaminated fluid.

[0280] The flow through the mesh fabric on the filter basket 84 ensures a smooth flow. This supports the dripping of contaminated liquid toward the container bottom 86. The entrainment of contaminated water in the air stream toward the cover device 78 (toward the passage openings 162a, 162b) is thereby effectively suppressed.

[0281] Furthermore, coarse dirt remains at the defined location in the filter basket 84. Fine dirt is transported to the first filter device 80.

[0282] As a result of this and further enhanced by the annular wall 194, liquid drips into the receiving space 90 in a defined manner.

[0283] A vacuum is applied to the filter basket 84 via the suction flow. This frees the coarse dirt trapped there from the liquid. A type of flushing of the filter basket 84 takes place. This negative pressure on the filter basket 84 causes the coarse dirt accumulating there to dry. Finer dirt particles can bind in the liquid and be transported into the receiving space 90 of the container 76. The constant flushing with liquid also increases the time until the filter basket 84 becomes clogged with dirt, especially coarse dirt.

[0284] In the solution according to the invention, coarse dirt remains in a defined location, namely in the filter basket 84.

[0285] The container 76 can be easily rinsed and cleaned because the flow tube 102 is outside the receiving space 90.

[0286] Overall, the separator container device 58 is designed with few "dead areas" in which dirt such as oat flakes can get stuck.

[0287] As mentioned above, the separator container device 58 has a self-cleaning effect.

[0288] The separator-container device 58 can be operated largely independently of its position (relative to the angle ß). The effective separation between liquid and air and the anti-spill protection provided by the anti-spill device 180 effectively prevent liquid from escaping from the outlet device 136.

[0289] The anti-slosh strips 182, 184 form anti-slosh ribs that retain liquid and ensure that it cannot reach the airflow area (of stream 226). Furthermore, the anti-slosh plate 212 and the annular wall 194 provide such effective anti-slosh protection. This allows, for example, the angle ß of 90° to be used as a parking position and 0° when operating the floor cleaning machine 10 as an underrun position for furniture and the like.

[0290] Furthermore, the separator container device 58 can then also be easily emptied. In particular, dirty water and coarse dirt can be emptied separately. To empty the dirty water, the lid device 78 is removed, and without having to remove the basket holder 82, the contaminated liquid in the receiving space 90 can be emptied through the openings 162a, 162b. This is achieved by tilting the container 76.

[0291] Coarse dirt can be emptied by removing the filter basket 84 and emptying it.

[0292] The separator-container device 58 can be used advantageously when the sucked-in dirty fluid stream contains liquid. This is the case, for example, with the floor cleaning device 10, in which liquid is discharged via the cleaning roller 16.

[0293] Another example of a corresponding cleaning machine is a wet / dry vacuum cleaner, which can be used to vacuum areas containing liquid.

[0294] In principle, the separator-container device 58 according to the invention can also be used if the dirty fluid flow does not contain liquid. In this case, too, dirt can be separated, and coarse dirt can be collected in the filter basket 84 and fine dirt in the receiving chamber 90.

[0295] In the solution according to the invention, the flow pipe 102 is positioned outside the receiving space 90. The coupling of the dirty fluid flow 220 into a separator device of the separator-container device 58 takes place via the cover device 78. It is fundamentally possible, as shown schematically in Figure 11, for a corresponding flow pipe 230 to be part of a cleaning machine 232 and, in particular, to be firmly connected thereto. A corresponding separator-container device 234 is then provided, which is then connected to the flow pipe 230 of the cleaning machine 232 via a corresponding inlet device 120 on the cover device 78.

[0296] In this embodiment, the flow pipe 230 is not connected to the corresponding container 236, but is an integral part of the cleaning machine 232.

[0297] The mode of operation is basically the same as described above using the separator container device 58.

[0298] In a further embodiment of a separator-container device 238, which is shown schematically in Figure 12, a flow tube 240 is fixedly connected to a cover device 78'. The cover device 78' with the flow tube 240 is a removable unit with respect to a container 236. The flow tube 240 itself can be permanently or removably connected to the cover device 78', particularly for cleaning purposes.

[0299] In the separator-container device 238, the flow tube 240 is not permanently connected to the container 236, but is unconnected or detachably connected, for example by one or more clamps.

[0300] Otherwise, the separator-container device 238 functions like the separator-container device 58.

[0301] According to the invention, the entire dirty fluid flow provided by the cleaning machine 10 is introduced into the basket space 152 of the filter basket 84. In one embodiment, the introduction takes place via the cover device 78, although introduction without the involvement of the cover device 78 is also possible in principle.

[0302] Dirty liquid then flows through the basket wall 150 into the collecting space 101 as a part of the receiving space 90 between the basket bottom 148 and the container bottom 86 and collects there.

[0303] The air flow coupling between the outlet device 136 and the receiving space 90 is located outside the filter basket 84 and thus also outside the basket space 152 and the basket wall 150 in the space 159.

[0304] The passage openings 192a, 162b point into the space 159, which lies outside the filter basket 84 and in particular surrounds the filter basket 84.

[0305] As mentioned above, this causes a relatively dry (contaminated) air flow to be decoupled, in particular via the cover device 78.

[0306] An effective separation of coarse dirt (which remains in the filter basket 84), dirty liquid which accumulates in the collecting space 101 of the receiving space 90 between the container bottom 86 and the filter basket 84, and air which is discharged via the passage openings 162a, 162b outside the filter basket 84 can be achieved.
