The CN 113331730 A reveals a dirt container.

The CN 217013863 U reveals a cleaning device.

The CN 217066276 U , the CN 216823273 U , the CN 216823275 U , the CN 216823274 U , the CN 216167279 U , the CN 216754364 U , the CN 216256943 U , the CN 216221342 U , the CN 216754365 U and the CN 213429906 U also reveal cleaning equipment.

The WO 2016/141963 A1 discloses a vacuum cleaner with a housing which extends between a first housing side and a second housing side in an extension axis. A suction unit for generating a suction flow is provided, which is arranged in the housing. Furthermore, a separator device is arranged in the housing.

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.

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.

The solution according to the invention makes it possible to effectively separate coarse dirt from fine dirt in the separator container device and, in particular, also to separate liquid.

By coupling the dirty fluid flow to the cover device, a filter device can be continuously flushed through when the cleaning machine is in operation with the separator container device. In addition, a coarse dirt collection area can be dried using the negative pressure applied.

Furthermore, there is a large recording volume for the recording room.

The receiving space and other flow-exposed elements of the separator container device can be made “smooth” in order to effectively prevent dirt from getting caught in cracks or the like.

An outlet device for an air flow is arranged on the cover device. This results in a compact structure. Effective separation can be achieved. The cover device forms a type of communication center for fluid in the separator container device. A dirty fluid flow is coupled in via the inlet device on the cover device and then fed to a filter device, in particular in the form of a filter basket. The inlet device on the cover device can be used to effectively couple to a blower device and to easily apply a suction flow.

The separator-container device is in particular a separator-container device which is intended to be supplied with a liquid-containing dirty fluid. In particular, the container can then also hold dirty fluid, i.e. the container has a collecting space for dirty fluid.

For the same reason, it is advantageous if the cover device has a connection for a blower device of the cleaning machine. This results in a compact structure. A connection to the cleaning machine can be achieved in a simple manner.

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 at least a flow pipe is fluidly connected or can be connected, which has a connection for the cleaning machine for coupling in a dirty fluid flow. This makes it possible to effectively create 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.

• - der Behälterboden ist durchgehend und öffnungslos und/oder anschlusslos ausgebildet;
• - der Behälterboden ist als Platte und insbesondere als ebene Platte und/oder Flachplatte ausgebildet.

It is advantageous if at least one of the following is provided:

• - the container bottom is continuous and has no openings and/or connections;
• - the container bottom is designed as a plate and in particular as a flat plate and/or flat plate.

This allows the container to be made "smooth" on the inside and effectively prevents dirt and the like from getting stuck. This makes it easy to empty a full container and also easy to clean. It also provides a large storage capacity.

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

It is particularly advantageous if the at least one flow pipe is positioned outside the receiving space. This allows a dirty fluid flow to be effectively coupled to the inlet device of a cover device and coupled into the container via the cover device. Furthermore, cracks and the like in the receiving space, where dirty fluid can settle, can be largely avoided. Furthermore, a compact structure results.

• - das mindestens eine Strömungsrohr ist als Steigrohr ausgebildet, wobei in einem normalen Betriebszustand ein Schmutzfluidstrom in dem mindestens einen Strömungsrohr eine Strömungskomponente entgegen der Schwerkraftrichtung aufweist;
• - in einem normalen Betriebszustand ist die Deckeleinrichtung bezogen auf die Schwerkraftrichtung oberhalb des Behälterbodens positioniert;
• - es ist genau ein Strömungsrohr vorgesehen.

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 against the direction of gravity;
• - in a normal operating condition, the lid device is positioned above the container bottom with respect to the direction of gravity;
• - exactly one flow pipe is provided.

By designing the at least one flow pipe as a riser pipe, a compact structure is achieved, for example when arranged on a support rod device of a hand-held cleaning machine. By designing the flow pipe as a riser pipe or as a standpipe, dirty fluid can be effectively fed to the cover device, and a liquid-laden stream of dirt can then flow downwards into the container from the cover device, driven by gravity.

• - das mindestens eine Strömungsrohr und/oder die Einlasseinrichtung an der Deckeleinrichtung ist dezentral zu dem Behälterboden positioniert;
• - die Einlasseinrichtung an der Deckeleinrichtung ist außerhalb einer Projektionsfläche des Aufnahmeraums positioniert, wobei die Projektionsfläche senkrecht zu einer Höhenachse des Aufnahmeraums ist;

• - das mindestens eine Strömungsrohr verläuft, zumindest wenn die Abscheider-Behälter-Vorrichtung an der Reinigungsmaschine positioniert ist, längs der Behälterwandung.

Furthermore, it is advantageous if at least one of the following is provided:

• - relative 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 bottom and/or next to the container wall;
• - relative to a transverse direction to a vertical axis of the receiving space, the at least one flow pipe is spaced from the container bottom and/or spaced from the receiving space and/or spaced from the container wall;
• - the inlet device on the lid device is positioned offset to the receiving space in a transverse direction to a vertical axis of the receiving space and/or offset to the container bottom;
• - the at least one flow pipe and/or the inlet device on the lid device is positioned decentrally to the container bottom;
• - 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 vertical axis of the receiving space;
• - the at least one flow pipe runs along the container wall, at least when the separator-container device is positioned on the cleaning machine.

The arrangement of the flow pipe next to the receiving space or container floor or container wall results in a compact structure. The settling of dirt in the container can be effectively reduced. This results in easy coupling of dirty fluid to the lid device.

• (i) parallel zu einer Höhenachse des Aufnahmeraums;
• (ii) quer und insbesondere senkrecht zu dem Behälterboden;
• (iii) in einer Richtung verlauft, welche parallel zu einer Richtung von dem Behälterboden zu der Deckeleinrichtung hin ist.

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:

• (i) parallel to a vertical axis of the recording space;
• (ii) transversely and in particular perpendicular to the container bottom;
• (iii) extends in a direction which is parallel to a direction from the container bottom towards the lid means.

This results in effective flow guidance. It results in a compact structure. A large storage volume can be provided for the container.

It is advantageous if the at least one flow pipe has an inlet and an outlet, wherein the outlet is connected or can be connected to the inlet device on the cover device, and wherein the inlet is connected or can be connected 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.

• - an dem Eingang erfolgt eine fluidwirksame Ankopplung der Abscheider-Behälter-Vorrichtung an die Reinigungsmaschine;
• - das mindestens eine Strömungsrohr erstreckt sich von dem Eingang zu der Deckeleinrichtung.

It is also advantageous if at least one of the following is provided:

• - the inlet is arranged at a second end of the at least one flow tube;
• - a sealing device is assigned to the outlet;
• - a sealing device is assigned to the inlet;
• - the entrance is located at the same height as the container bottom in relation to a vertical axis of the receiving space or is offset from the container bottom in relation to the vertical axis;
• - at the inlet, a fluid-effective coupling of the separator-container device to the cleaning machine takes place;
• - the at least one flow tube extends from the inlet to the cover device.

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

• - das mindestens eine Strömungsrohr ist mit dem Behälter verbunden und insbesondere unlösbar verbunden;
• - das mindestens eine Strömungsrohr ist an einer Außenseite des Behälters oder im Bereich einer Außenseite des Behälters positioniert;
• - das mindestens eine Strömungsrohr ist mit der Behälterwandung verbunden und/oder in die Behälterwandung integriert;
• - das mindestens eine Strömungsrohr ist einstückig mit der Behälterwandung verbunden;
• - das mindestens eine Strömungsrohr sitzt an einem Mantel des Behälters.

In one embodiment, at least one of the following is provided:

• - the at least one flow pipe is connected to the container and in particular is non-detachably connected;
• - the at least one flow pipe 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 pipe is connected to the container wall and/or integrated into the container wall;
• - the at least one flow pipe is integrally connected to the container wall;
• - at least one flow pipe is located on a shell of the container.

The at least one flow tube is then a fixed component of the container. The cover device is then in particular detachable from the at least one flow tube 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 in relation to a transverse direction to a vertical axis of the receiving space. This results in a compact structure. In particular, the separator-container device with the flow pipe can be positioned on the inside of a holder of the cleaning machine in order to obtain an effective interface for transferring dirty fluid.

It is advantageous if the at least one flow pipe is located on a central plane of the container, with a vertical axis of the receiving space being in the central plane, and in particular with a handle of the container being in the central plane. This results in a compact structure. The separator-container device can be easily fixed to a cleaning machine or removed from there.

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 is positioned on the container facing away from the flat side. This results in a compact structure. The separator-container device can be effectively fixed to a cleaning machine. A large receiving volume can be provided.

In one embodiment, the container has a recess on the flat side for the at least one flow tube. This results in a compact structure.

In particular, the lid device is detachable from the at least one flow tube in order to enable access to the container.

It can also be provided that the at least one flow pipe is fixed to the cover device.

In particular, the cover 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 cover device. If the cover 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.

It is also possible that the at least one flow pipe is part of the cleaning machine and in particular that the separator container device is removable from the at least one flow pipe. In particular, the at least one flow pipe then remains on the cleaning machine.

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 separator-container device is connected directly to a blower device via the clean side. The separator-container device is connected to the cleaning machine on the dirty side via the flow pipe or directly via the cover device. The interface for introducing a dirty fluid flow from the cleaning machine into the separator-container device is located on the dirty side connection.

In particular, the lid device is positioned on the container so that it can be opened and, in particular, can be removed from the container as a whole. This makes it easy to empty the container. Furthermore, this also makes it easy to remove a filter basket that is positioned on the container.

In one embodiment, the cover device has a receptacle for a (first) filter device, on which the filter device is seated in particular in a removable manner. This makes it possible to filter a dry stream of dirt in particular.

• - die Filtereinrichtung ist oder umfasst einen Feinstaubfilter und/oder Motorschutzfilter;
• - eine Reinseite der Filtereinrichtung liegt an einer Auslasseinrichtung der Deckeleinrichtung für einen Luftstrom;
• - die Filtereinrichtung umfasst einen Flachfaltenfilter.

It is advantageous if at least one of the following is provided:

• - the filter device is or includes a fine dust filter and/or engine 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.

The separator container device is preferably coupled directly to a blower device of the cleaning machine via the cover device, i.e. a suction flow is applied via the cover device. The corresponding suction flow can be particularly contaminated with fine dust. The (first) filter device ensures appropriate filtering and thus motor protection.

In particular, the receptacle is open to an upper side of the cover 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 structure that is easy to remove. Furthermore, the separator-container device can be connected to the blower device on one side in a structurally simple manner.

It is particularly advantageous if at least one deflection pipe is arranged on the cover device, which is fluidically connected to the inlet device. The deflection pipe can be used to divert the flow. This directs a stream of dirty fluid into the container. This in turn makes it easy to achieve a separating effect.

• - der Auslass ist dem Behälterboden zugewandt;
• - der Auslass weist eine Öffnungsnormale auf, welche parallel oder in einem spitzen Winkel kleiner als 30° zu einer Höhenachse des Aufnahmeraums orientiert ist;
• - der Auslass weist eine Öffnungsnormale auf, welche quer und insbesondere senkrecht zu dem Behälterboden orientiert ist;
• - der Auslass weist eine Öffnungsnormale auf, welche parallel oder in einem spitzen Winkel kleiner als 30° zu der Behälterwandung orientiert ist;
• - der Auslass weist eine Öffnungsnormale auf, welche parallel oder in einem spitzen Winkel kleiner als 30° zu mindestens einem Strömungsrohr orientiert ist;
• - an dem mindestens einen Umlenkrohr ist die Einlasseinrichtung an der Deckeleinrichtung angeordnet;
• - das mindestens eine Umlenkrohr ist so angeordnet und ausgebildet, dass eine Hauptströmungsrichtung für Schmutzfluid bei Ausströmung aus dem Auslass entgegengerichtet oder in einem spitzen Winkel kleiner als 30° zu einer Hauptströmungsrichtung von Schmutzfluid bei Einkopplung an der Einlasseinrichtung an der Deckeleinrichtung und/oder zu einer Hauptströmungsrichtung in mindestens einem Strömungsrohr orientiert ist.

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 bottom of the container;
• - the outlet has an opening normal which is parallel or at an acute angle is oriented at less than 30° to a vertical axis of the recording room;
• - the outlet has an opening normal which is oriented transversely and in particular perpendicular 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 that 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 in at 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 fed into a filter basket in particular via the outlet. This makes it easy to separate the liquids, so that an air flow to a blower device in particular does not carry liquid with it. A coarse dirt container can be constantly flushed through via the dirty fluid flow. This increases the time until the coarse dirt container becomes clogged with dirt. Coarse dirt can also be dried effectively in the coarse dirt container due to the negative pressure applied. Fine dirt can bind to liquid and be transported away.

In relation to a vertical axis of the receiving space of the container, a (first) filter device, in particular for dry dust, is positioned above the at least one deflection pipe. This results in an effective structure. The cover device thus forms a type of fluid communication center of the separator-container device.

It is particularly advantageous if a (second) filter device is provided with at least one filter basket, which is assigned to the cover device, wherein a dirty fluid flow, which is coupled via the inlet device on the cover device, is guided into the filter basket and in particular is guided 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 is 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.

The filter basket can be used to create an effective separator, whereby coarse dirt is filtered out of a dirty fluid flow coupled in (via the cover device) and collected. Liquid can drip off and be collected in the receiving space. This means that an air flow, which is coupled in particular into the cover device for removal (direct coupling with the blower device), can be realized as dry, since the proportion of liquid that is drawn along in the air flow is minimized.

In particular, the at least one filter basket has 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 structure.

It is particularly advantageous if a collecting space for dirty liquid is formed in the container between the container base and the basket base. 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.

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 is therefore a sieve basket. The mesh (sieve fabric) also ensures that the flow is smoothed. This in turn means that liquid can drip off and is not carried along by an air stream. This allows a relatively dry provide a (dirty) air stream, which is then discharged in particular via a first filter device.

It is advantageous if the mesh size of the mesh fabric is in the range between 50 µm and 300 µm. This results in an effective coarse dirt collection function with effective separation function and flow smoothing function.

In particular, an outlet of at least one deflection pipe, which is fluidically connected to the inlet device on the cover device, opens into the basket space and in particular on a central axis of the basket space into the basket space. This effectively allows a dirty fluid flow from the cover device to be transferred to the container with a coarse dirt collection function, liquid collection function and separation function.

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

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. As a result, the filter basket can be positioned at a distance from a corresponding receiving base of the basket holder, and a flow can take place between the basket base and the receiving base.

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 is in particular detachably connected. The basket holder holds the filter basket and can also have other functions such as holding a splash protection device, providing a drip tray, holding a sensor and so on.

• - der Korbhalter ist von dem Behälter und/oder von der Deckeleinrichtung entnehmbar;
• - der mindestens eine Filterkorb ist von dem Korbhalter entnehmbar.

It is advantageous if at least one of the following is provided:

• - the basket holder can be removed from the container and/or the lid device;
• - at least one filter basket can be removed from the basket holder.

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

• - der Korbhalter sitzt lösbar an dem Behälter;
• - die Deckeleinrichtung ist von dem Behälter und dem Korbhalter lösbar auf dem Korbhalter positioniert.

In particular, the basket holder is an element separate from the lid device, in particular with at least one of the following:

• - the basket holder is detachably attached to the container;
• - the lid device is positioned on the basket holder so that it can be detached from the container and the basket holder.

This makes it easy to empty and clean.

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 structure.

It is also advantageous if the basket holder has a receptacle for the at least one filter basket, which 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, this also makes it easy to implement a separator, which in particular carries out coarse dirt separation and liquid separation.

It is particularly advantageous if the receiving base and the receiving wall of the receptacle are closed and at least one outlet opening and in particular exactly one outlet opening is provided for fluid-effective connection to the receiving 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. By appropriate arrangement and design, a "drip" of liquid from the receptacle into the receiving space of the container can be achieved in an effective manner. An air flow guidance can be achieved that makes it possible to provide an essentially dry air flow at an outlet device of the separator-container device.

• - die mindestens eine Austrittsöffnung ist an der Aufnahmewandung angeordnet;
• - die mindestens eine Austrittsöffnung erstreckt sich bis zu dem Aufnahmeboden;
• - die mindestens eine Austrittsöffnung weist eine Ausdehnung in einer Umfangsrichtung über einen Winkelbereich von mindestens 10° und insbesondere mindestens 15° auf;
• - die mindestens eine Austrittsöffnung weist eine Ausdehnung in einer Umfangsrichtung über einen Winkelbereich von höchstens 40° auf;
• - die mindestens eine Austrittsöffnung weist einer Seite des Behälters zu, an welcher mindestens ein Strömungsrohr positioniert ist;
• - die mindestens eine Austrittsöffnung weist einer Seite des Behälters zu, welche abgewandt zu einer Seite mit einem Handgriff ist;
• - die mindestens eine Austrittsöffnung weist einer Seite zu, welche bei ordnungsgemäßer Neigung der Abscheider-Behälter-Vorrichtung zur Schwerkraftrichtung bezogen auf die Schwerkraftrichtung obenliegend ist.

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 to 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 tube 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.

The appropriate design of the at least one and in particular exactly one outlet opening results in an effective separation function. Furthermore, the appropriate design of the outlet opening makes it possible to achieve a substantially inclination-independent reception and separation function of the separator-container device. For example, the separator-container device can also be operated when the vertical axis of the receiving space of the container is not parallel to the direction of gravity and is, for example, perpendicular to the direction of gravity.

In one embodiment, the basket holder has a flange on which a receptacle for the at least one filter basket is located, the flange being intended to cover the container. An effective air flow can be achieved via the flange. It is also possible to empty the basket holder when it is attached to the container through corresponding openings in the flange. This results in a structurally simple design.

• - die mindestens eine Durchtrittsöffnung stellt eine fluidwirksame Verbindung zu einer Auslasseinrichtung für einen Luftstrom her, wobei insbesondere die Auslasseinrichtung an der Deckeleinrichtung angeordnet ist;
• - durch die mindestens eine Durchtrittsöffnung lässt sich der Aufnahmeraum des Behälters bei abgenommener Deckeleinrichtung ohne Abnahme des Filterhalters leeren.

It is advantageous if at least one passage opening is arranged on the flange, with at least one of the following:

• - the at least one passage 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 at least one opening, the receiving space of the container can be emptied when the lid device is removed without removing the filter holder.

The container can be emptied via the at least one passage opening without having to remove the basket holder. Furthermore, an air flow connection to the lid device can be provided via the at least one passage opening in order to effectively discharge an air flow or to enable a suction flow to be applied.

It is particularly advantageous if the at least one passage opening on the flange is fluidically adjacent to at least one outlet opening on a receptacle for the at least one filter basket. This allows a (dirt-laden) air flow to be discharged via the at least one passage opening in order to in turn enable a clean-side coupling to a blower device in an effective manner, i.e. to provide a clean-side interface to a cleaning machine.

It is particularly advantageous if an airflow-effective connection (in particular via the at least one passage opening) of the outlet device with the container is positioned outside the filter basket (outside a basket space of the filter basket) and is positioned in particular 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 sucked out from outside the filter basket and in particular in the space around the filter basket, i.e. this space is in direct fluid-effective connection with the outlet device. This results in an effective separation function, in particular for a liquid-laden dirty fluid.

In one embodiment, at least one sensor for determining the fill level for the receiving space of the container is positioned on the basket holder. This results in a compact structure. The basket holder, which is already present, is then also used as a sensor holder.

In one embodiment, the at least one sensor is arranged on a splash guard strip. This results in an effective and compact structure.

It is particularly advantageous if a splash protection device is arranged on the basket holder. This allows the existing basket holder to be used effectively. The splash protection device 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 independently of the inclination.

In one embodiment, the anti-sloshing device comprises at least one anti-sloshing strip and in particular two anti-sloshing strips, which ensure a seal between the basket holder and the container wall. This prevents liquid from sloshing outside a desired area. Furthermore, effective flow guidance, especially air flow guidance, is achieved. This in turn enables an effective separator function to be implemented.

It is furthermore advantageous if a first splash guard strip and a second splash guard strip are provided, which are spaced apart from one another, with at least one of the following:

• - the first anti-slosh strip and the second anti-slosh strip are oriented at least approximately parallel to each other;
• - at least one outlet opening of the basket holder is positioned between the first splash guard strip and the second splash guard strip;

This results in a compact structure. The anti-splash strips with the anti-splash function are used as holders. By defining a space in the container in which there is an outlet opening for the basket base and at least one opening to an outlet device for an air flow, an effective flow guidance with an effective separator function can be achieved.

The ring wall also provides an anti-splash function and can be used to create a drip tray.

In one embodiment, the anti-sloshing device has at least one anti-sloshing plate, which is assigned to at least one outlet opening of the basket holder. The anti-sloshing plate can effectively prevent or at least reduce liquid sloshing at the at least one outlet opening, even when the separator container device is in a lying or approximately lying state, in which the vertical axis of the receiving space is oriented transversely to the direction of gravity.

• - der spitze Winkel liegt im Bereich zwischen 30° und 60° und insbesondere im Bereich zwischen 35° und 55°, und insbesondere im Bereich zwischen 40° und 50°.

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 against 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 has an extension in a transverse direction to a vertical axis of the receiving space of the container;
• - the at least one anti-slosh plate rests against a container part wall, the container part wall being 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 against 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 one end of the at least one anti-slosh plate, with which this is attached to a container part wall of the container wall, to the at least one outlet opening and relative to a height axis of the receiving space is greater than a distance of an opposite end of the at least one anti-slosh plate to the at least one outlet opening;
• - the acute angle is 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°.

The at least one anti-slosh plate covers the outlet opening at a distance from the outlet opening to a certain extent with respect to the vertical axis of the receiving space in order to effectively reduce the sloshing of liquid into the outlet opening.

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, in particular for guiding liquid. The annular wall enables effective dripping of liquid, which comes in particular from at least one outlet opening of a basket holder receptacle. This in turn makes it possible to supply a substantially dry air stream (which may still contain fine dirt) to the lid device. This enables an effective separator function to be achieved with regard to both coarse dirt and liquid.

In particular, the ring wall has a front side facing the container bottom, and the front side is assigned an envelope plane, wherein the envelope plane is oriented at an acute angle to a vertical axis of the receiving space of the container. This results in an anti-sloshing function. This results in an effective liquid drainage function. The ring wall forms a type of drip tray to effectively drain liquid and then collect it in the receiving space.

It has proven to be advantageous if the acute angle is in a 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°. In a specific embodiment, the acute angle is 45°.

It is then furthermore advantageous if a distance of the envelope plane to a receiving base of the basket holder increases in the direction of 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 in the vicinity of the at least one outlet opening.

In order to achieve effective liquid drainage with effective liquid conduction, the ring wall is open towards the container bottom and towards an inner side of a container part wall. Through the opening to an inner side of the container part wall, liquid that comes from at least one outlet opening of a receptacle of the basket holder can be collected and directed. The opening towards the container bottom prevents accumulation and thus achieves effective drainage.

In particular, the container has an area in the receiving space of the container towards which the ring wall is open, wherein at least one outlet opening of the basket holder is located in the 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 ensure that a substantially dry, dirt-laden air flow is guided to the cover device and that an effective clean-side interface for a blower device of the cleaning machine is present on a clean side of the cover device after filtering.

At least one anti-splash plate is preferably positioned on the ring wall and in particular outside an interior of the ring wall. The ring wall serves as a holder for the at least one anti-splash plate, resulting in a simple structural design. The at least one anti-splash plate ensures that dirty liquid cannot enter the at least one outlet opening, in particular when the separator container device is "lying".

It is advantageous if the at least one anti-slosh plate has at least the same angular orientation as an envelope plane of the ring wall. This results in an effective anti-slosh effect.

In one embodiment, the separator-container device has an upper side which faces away from the container bottom and on which an outlet device for connection to a blower device is arranged, wherein the upper side is assigned an envelope plane, and wherein the envelope plane is oriented at an acute angle to a vertical axis of the receiving space of the container. This allows the separator-container device to be easily oriented to a receptacle of the cleaning machine. It is easy to Insert to achieve a fluid-tight coupling to the blower device.

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 sits 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 connection with a part of the receiving space outside the filter basket.

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 already been explained above.

The entire (and particularly liquid-containing) dirty fluid flow is fed into the filter basket. Coarse dirt can be collected there. Dirty fluid can then be collected from the filter basket in the collection space (as a part of the container's receiving space) below the filter basket between the filter basket and the container floor. A relatively dry (dirt-containing) air flow can be extracted from outside the filter basket (but still inside the container) and particularly in a space around the filter basket.

This results in an effective separation of coarse dirt, liquid and air.

It is advantageous if the part of the receiving space which is in direct fluid connection to the extraction of the air flow surrounds the filter basket. This results in an effective separation function.

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 partial wall.

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 already been explained above.

Coarse dirt can be collected via the filter basket.

An effective separator function is achieved for coarse dirt and also for liquid. Liquid can be dripped off (into a collecting chamber), whereby a defined guidance of liquid takes place along the ring wall in order to fill the receiving container.

The filter basket can be used to smooth out a coupled flow. This causes dirty liquid to drip down to the bottom of the container. The ring wall, in turn, improves the drainage of liquid; it provides a kind of drip tray.

The filter basket can be flushed with liquid. There is also a negative pressure on the filter basket. This dries coarse dirt. Fine dirt can bind to liquid and can then be partially transported into the container's receiving space.

Furthermore, the constant flushing of the filter basket increases the time until the filter basket becomes clogged.

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 connected to the blower device in a fluid-effective manner.

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

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

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 This results in an effective connection.

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 lies below the filter basket between the filter basket and the container bottom, and in which an air flow discharge takes place, wherein the air flow is discharged from a partial area of the receiving space outside the filter basket.

This results in an effective separation function in which coarse dirt, which is collected in the filter basket, can be separated from dirty liquid. The dirty liquid is collected in the collection space below the filter basket. In addition, a relatively dry, dischargeable air stream can be provided, which is then discharged from the part of the collection space outside the filter basket.

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 structural details of the corresponding method have been explained in connection with the device.

In particular, it is provided that the part 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 dirty fluid is coupled into the filter basket at least approximately centrally and is coupled into a basket space. The air flow discharge then takes place decentrally in a part of the receiving space outside the filter basket.

An embodiment of a cleaning machine according to the invention is a floor cleaning machine 10 ( 1 ). The floor cleaning machine 10 is used 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.

The floor cleaning machine 10 comprises a cleaning head 14 (floor head). During a cleaning process, the floor cleaning machine 10 is positioned via the cleaning head 14 on the floor 12 to be cleaned.

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

The cleaning head 14 has further support means 20 in order to support 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.

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

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

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 the cleaning head 14 accordingly 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.

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.

In the graphic representation according to 1 the pivot axis 34 is perpendicular to the drawing plane.

Due to the pivotability of the joint device 24 about the pivot axis 34, a pivot position of the holding rod device 26 to the floor 12 can be varied. This is shown in 1 indicated by arrow 36.

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

When the floor cleaning machine 10 is operated, the holding rod device 26 is moved out of the parking position. By pivoting about the pivot axis 34 on the joint device 24, an operator can adjust it to his body size.

Furthermore, the aforementioned pivotability allows an operator to, for example, drive under furniture or the like; he can reduce the overall height of the floor cleaning machine 10 between the installation plane 22 and a proximal end 38 of the holding rod device 26 accordingly.

In 1 a swivel angle β is indicated. The holding rod device 26 is basically between β approximately 90° ( 1 ) to β close to 0° (parallel alignment to the floor 12). The corresponding swivel angle β can also be limited to 5° or 10°, for example.

A handle 40 for an operator is located at the proximal end 38 of the holding rod device 26. In one embodiment, the handle 40 is designed as a circumferential bow handle.

The cleaning head 14 is articulated to a distal end 42 of the holding rod device 26 via the articulation device 24.

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

A blower device 46 is located in the housing device 44. The blower device 46 comprises a blower for generating a negative pressure flow (suction flow). It also comprises a motor and in particular an electric motor for driving at least one fan wheel of the blower.

A connection 48 is arranged on the machine side of the housing device 44, via which the suction flow can be "tapped". The connection 48 is located on a clean side.

A further connection 50 is arranged on the housing device 44, at which the suction flow generated by the blower device 46 can be guided to the cleaning head 14; the cleaning head 14 can be subjected to the corresponding negative pressure flow via the further connection 50 in order to be able to discharge a dirty fluid.

It is particularly provided that the floor cleaning machine 10 has a discharge device 52, via which the suction flow can act on the cleaning head 14.

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

The additional connection 50 is located on a dirty side of the floor cleaning machine 10.

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 flow 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.

The separator container device 58 serves to receive and collect dirt. It also has a separator function to separate an air flow from dirt in order to be able to establish the fluid-effective connection with the blower device 46 at the connection 62.

Basically, the separator-container device 58 is also designed in such a way that it can be supplied with a dry dirty fluid flow (via the connection 60) or with a dirty fluid flow containing liquid. In the case of a dirty fluid flow containing liquid, the separator-container device 58 also has the task of causing liquid separation.

The separator-container device 58 according to the invention is advantageously used in conjunction with a cleaning machine 10 which carries out wet cleaning, so that the dirty fluid flow contains 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.

For the purposes of this application, a dirty fluid is understood to be a flowable medium containing dirt. As mentioned above, the dirty fluid can be dry and contain, for example, coarse dirt particles and also fine dirt particles. In principle, it can also be liquid and contain, for example, water with, for example, coarse dirt particles and fine dirt particles.

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

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

The housing device 44 has a side 64 which faces away from a holding rod 66 of the holding rod device 26. The receptacle 56 borders on the side 64 and forms a recess with respect to the side 64.

When the separator-container device 58 is positioned on the holding rod device 26 and thereby 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 flush 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.

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

The connections 48 and 50 are positioned at a height distance from one another on the holder 56. The connection 50 is closer to the cleaning head 14 or to the distal end 42 of the holding rod device 26.

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

A tank 72 for a cleaning liquid is located on the housing device 44, facing away from the receptacle 56. The tank 72 is intended in particular for holding fresh water, to which a surfactant cleaning agent can optionally be added.

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.

In particular, a scraper is provided which is assigned to the cleaning roller 16. Dirty fluid can be scraped off the textile material of the cleaning roller 16 via the scraper. The dirty fluid can then be sucked off at the nozzle device 54 via the blower device 46.

Regarding the basic functionality of such a floor cleaning machine, the following example is given: WO 2015/086083 A1 referred to.

Cleaning fluid from the tank 72 can be supplied to the cleaning head 14 by gravity or, for example, by means of a pump.

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.

For the floor cleaning machine 10 according to 1 faces the side 64 of the housing assembly 44 toward the rear end 30 of the cleaning head 14. The tank 72 faces the front end 28.

This means that when the holding rod device 26 is pivoted about the pivot axis 34 while reducing the angle β, the separator-container device 58 is pivoted towards the base 12 and the separator-container device 58 lies between the holding rod 66 and the base 12.

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.

An embodiment of a separator-container device 58 according to the invention, which is shown in the 2 to 10 comprises as essential components a container 76, a lid device 78, a first filter device 80 which sits 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 located all around. A receiving space 90 is formed between the container wall 88 and the container base 86.

The receiving space 90 has a vertical axis 92. The vertical axis 92 is transverse and in particular perpendicular to the container bottom 86.

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.

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

The receiving space 90 has a volume which is typically in the range between 0.5 l and 1.5 for the use 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.

The container bottom 86 is closed and has no connections. In particular, it is plate-shaped.

In one embodiment, the container base 86 has a raised portion 94 that projects into the receiving space 90, the raised portion 94 having an opening 96 on the outside. An element of a fixing device of the floor cleaning machine 10, which is arranged on the receiving means 56, can be inserted into the opening 96 in order to obtain a positive fixing in transverse directions transverse to the height axis 92 on the floor cleaning machine 10.

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 connected in one piece. It projects beyond the container bottom 86 in a direction parallel to the vertical axis 92.

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

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

The receiving space 90 comprises a collecting space 101 (see the 1 to 9 ) for dirty liquid. This collecting space 101 is a portion of the receiving space 90 between the container base 86 and the filter basket 84. Dirty liquid which exits from the filter basket 84 is collected in the collecting space 101 below the filter basket 84 in the container 76.

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

The flow tube 102 has an inlet 104 and an outlet 106. In the embodiment shown, the inlet 104 is located on the container bottom 86 with respect to the height axis 92, i.e. at the same height as the container bottom 86.

In principle, it is also possible for the inlet 104 to be offset (relative to the height axis 92) from the container bottom 86.

The outlet 106 of the flow tube 102 is located on the front side 100. The outlet 106 is in particular diametrically opposite to the handle 70.

The flow pipe 102 is designed in particular as a riser pipe. When the separator container device 58 is fixed to the floor cleaning machine 10, dirty fluid flowing in the flow pipe 102 rises against the direction of gravity g (compare 1 ) from the inlet 104 to the outlet 106. The corresponding conveying takes place through the blower device 46.

If the angle β is 1 is 90° or even greater than 90°, then the flow tube 102 does not act as a riser tube.

The further connection 50 is formed at the inlet 104. Via this, the container 76 of the separator container device 58 with the flow pipe 102 can be fluidly connected to the connection 60 of the cleaning machine 10 (and according to 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.

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

It is further provided in particular that the flow tube 102 can be plugged onto the connection 60 at the inlet 104. Accordingly, the connection 60 comprises a nozzle which projects in the direction of the receptacle 56.

An outer contour of the container 76 is adapted to the housing device 44 of the floor cleaning machine 10. In particular, the wall area of the container wall 88 outside the flat side 98 follows an outer contour of the housing device 44.

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

The basket holder 82 has a flange 108. The flange 108 can be placed on a ledge in the interior of the container 76 near the front side 100, and thereby the basket holder 82 can be held on the front side 100 of the container 76.

The basket holder 92 can be removed as a whole from the container 76. In 2 a state is shown in which the basket holder 92 has just been removed.

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

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. In 2 a state is shown in which the lid device 78 is removed from the container 76.

The lid device 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 immersion in 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 device 78 is placed on the basket holder 82.

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.

On the underside 112, a further nozzle 118 is arranged, which is assigned to the flow pipe 102. When the lid device 78 closes the container 76 properly, the nozzle 118 is immersed in the flow pipe 102 at the outlet 106. This creates a flow connection to the cover device 78 is established.

The cover device 78 has an inlet device 120 for dirty fluid. Dirty fluid is coupled from the flow pipe 102 into the cover device 78 via the inlet device 120. This inlet device 120 is formed on or by the nozzle 118.

The cover device 78 comprises a housing 122. The nozzle 116 and the nozzle 118 are seated on the housing 122.

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

A deflection pipe 124 is positioned in the housing 122 of the cover device 78. The deflection pipe 124 leads from the nozzle 118 to an opening 126. The opening 126 points into the opening 110 of the flange 108 or is arranged at the opening 110.

The deflection pipe 124 is fluidically 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.

The deflection tube 124 has an outlet 128 at the mouth 126. 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 height axis 92 of the receiving space 90 or parallel to a normal on the inside of the container bottom 86.

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.

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

The flow tube 102 has a longitudinal axis 132 which is parallel to the height axis 92 of the receiving space 90. The mouth normal 130 is parallel to the longitudinal axis 132 of the flow tube 102.

Dirty fluid is coupled into the cover device 78 at the inlet device 120 on the deflection tube 124 via the flow tube 102. 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 order to be able to fill the container 76, in particular via the cover device 78.

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.

A receptacle 134 is formed on the cover device 78, which is open to the upper 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 engine protection filter.

The separator container device 58 has an outlet device 136 which comprises 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.

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.

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

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.

The separator container device 58 also has a separation function, as explained in more detail below. In particular, coarse dirt can be separated from the dirty fluid flow at the second filter device 84. Furthermore, any dirty liquid can be separated there and collected in the receiving space 90.

Air can be guided as an air flow to the first filter device 80 and through it via the channel(s) 142, which are open to the basket holder 82. This air flow can may be contaminated with fine dirt particles. The first filter device 80 is 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 2 ).

The cover device 78 forms, so to speak, the fluid communication center of the separator-container device 58. After flowing through the flow pipe 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. An air flow that may be contaminated flows through the cover device 78 at the channel(s) 142 and is filtered and coupled out of the separator-container device 58 at the outlet device 136. The cover device 78 is therefore the communication center with the floor cleaning machine 10, whereby in the exemplary embodiment of the separator-container device 58, the inlet device 120 is, so to speak, extended by the flow pipe 102 and the direct coupling to the floor cleaning machine 10 takes place via the flow pipe 102 with its inlet 104.

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

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

Due to the envelope 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 and a tight connection is achieved.

As described above, the flow pipe 102 is located outside the receiving space 90 of the container 76. The nozzle 118 of the lid device 78 and thus also the inlet device 120 on the lid device 78 are then located, so to speak, next 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.

A projection of the inlet device 120 (the nozzle 118) in the height 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.

The filter basket 84 as a second filter device has a basket bottom 148 (compare for example 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 and in particular in one piece.

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

The filter basket 84 has a support structure 154 with continuous openings on the basket wall 150 and possibly also on the basket base 148. A mesh fabric, in particular 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.

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 bottom 148 towards an outer side (facing away from the basket space 152).

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

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

The basket holder 82 comprises, as mentioned above, 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 on a holding area 158.

Outside the holding area 158, a first through-opening 162a and a second through-opening 162b are arranged at a distance therefrom on the flange 108. Between the first through-opening The flange 108 has a free area 164 between the second opening 162a and the second passage opening 162b. The nozzle 118 extends through the free area 164 (when the basket holder 82 and the lid device 78 are seated on the container 76).

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

The passage openings 162a, 162b open into a space 159, which is a part of the receiving space 90 and is located above the collecting space 101. The space 159 (see also 9 ) is located outside the filter basket 84 and thus also outside the filter holder 82. The air flow is extracted outside the basket space 152.

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

In particular, it is provided that the coupling of dirty fluid into the basket space 152 via the mouth 126 is at least approximately central. The discharge of the air flow from the receiving space 90 from the space 159 is then decentralized.

The receptacle 160, which is formed on the holding area 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 firmly connected to the flange 108 on the holding area 158. The receiving base 166 is spaced from the flange 108.

The receiving base 166 is closed.

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 towards the flange 108; the flange 108 has an opening 172. This opening 172 in turn faces the cover device 78.

The filter basket 84 is positioned in the receiving space 170, wherein it stands on the receiving base 166 and is spaced from an inner side of the receiving base 166 via the spacer(s) 156 of the basket base 148.

The filter basket 84 can be removed or inserted via the opening 172 (if the cover device 78 is removed).

The receptacle 160 is provided with a window 174 in the receiving space 90 of the container 76. In particular, there is exactly one window 174. The window 174 forms an outlet opening 176 for a dirty fluid stream which has flowed through the filter basket 84.

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

In relation to the height axis 92 of the receiving space 90 of the container 76, the receiving space 170 of the basket holder 82 extends in a height direction. The window 174 does not take up the entire height of the receiving space 170, but 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 height axis 92.

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 in an angular range of at least 10° and in particular 15°. Furthermore, it is advantageous if the outlet opening 176 (the window 174) extends in an angular range of at most 40° and in particular at most 30°.

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

The passage openings 162a, 162b open into the region 178, i.e., there is a fluid-effective connection between the window 174 and the passage openings 162a, 162b through the region 178. As a result, there is also 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).

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

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 parallel to the Aligned with the height axis 92 of the receiving space 90 (when the basket holder 82 is seated on the container 76).

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.

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

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

The area 178 is located 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 strip 182 and/or the second splash guard strip 184 and is arranged in particular in the region of the lower end 186.

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.

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

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.

The ring wall 194 has a convexly curved shape with respect to the vertical axis 92. For example, it has the shape of a circular ring. It surrounds an interior space 196. The ring wall 194 defines an opening 198 towards the container bottom 86 (when the basket holder 82 is seated on the container 76), so that the interior space 196 is open via the opening 198 towards the container bottom 86.

The ring 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.

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

The opening 198 extends in a circumferential direction starting from an outer side of the receiving base 166. In particular, it is symmetrical to the window 174, starting directly below the window 174 and relative to a central plane 202 in which the height axis 92 lies.

The ring wall 194 has a front side 204 which faces the container bottom 86 and faces away from the receiving bottom 166 of the receptacle 160 of the basket holder 82. The front side 204 has an envelope plane 206 (for example 4 and 9 ). The envelope plane 206 is at an acute angle α (compare 3 ) to the receiving base 166. Accordingly, the envelope 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).

The acute angle α is in the range between 30° and 60° and in particular around 45°.

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

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

An angle range of 210 (compare 7 ), in which the ring 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, the angular range 210 is smaller than 300° and in particular smaller than 270° and in particular smaller than 230° due to the further opening 200.

In one embodiment, the further opening 200, which defines a window of the ring wall 194 in the region 178, is set back from the window 174 of the receptacle 160 with respect to the transverse direction 149.

The ring wall 194 forms a drip system for the targeted drainage of (dirty) liquid within the container 76. It also forms a splash guard.

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

When the basket holder 82 is positioned on the container 76, the anti-slosh plate 212 rests with one end 214 (compare 2 ) to a container wall 216 and ensures a seal there.

The anti-slosh plate 212 is at least with respect to an upper side at an acute angle 218 (compare 3 ) to the receiving base 166. It is oriented at this acute angle 218 to the height axis 92.

The acute angle 218 is in particular an opposite angle to the angle α and is, for example, in the order of magnitude of 45°.

At the end 214, the anti-slosh plate 212 is farther from the receiving bottom 166 than at an opposite end. Accordingly, the anti-slosh plate 212 is closer to the container bottom 86 at the end 214 than at the opposite end.

The anti-slosh plate 212 extends from the ring 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 with respect to the height axis 92.

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 β, 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.

It is also possible to provide several anti-slosh plates 212, which are then in particular spaced parallel to one another.

The basket holder 82 is detachably and removablely positioned on the container 76. The filter basket 84 is accommodated in the receptacle 160. When the floor cleaning machine 10 is operated with the separator container device 58, the cover device 78 sits on the container 76. It is positioned on the basket holder 82 and in particular the flange 108 with respect to the vertical axis 90.

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

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.

To empty the container 76 of liquid (which is particularly contaminated), the lid device 78 is removed from the container 76.

The through-openings 162a, 162b on the flange 108 are arranged in such a way that the basket holder 82 does not have to be removed in order to empty the receiving space 90 of the container 76, in particular of dirty liquid. Dirty liquid in particular 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 device 78 removed.

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

• Der Saugstrom der Gebläseeinrichtung 46 wird an der Auslasseinrichtung 136 an der Deckeleinrichtung 78 in die Abscheider-Behälter-Vorrichtung 58 eingekoppelt und durchströmt diese.

The separator-container device 58 functions as follows (see in particular the 4 and 10 ):

• 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.

Sucked-in dirty fluid is transferred in a dirty fluid stream 220 from the floor cleaning machine 10 to the flow pipe 102 at the inlet 104. With a main flow direction parallel to the height axis 92, Dirty fluid enters the flow tube 102 and is coupled into the cover device 78 at the inlet device 120. The dirty fluid flow is diverted 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.

Due to the mesh fabric on the filter basket 84, coarse dirt with a particle size above the mesh size cannot flow through the filter basket 84 and collects in the filter basket 84. This is in 4 indicated by the reference numeral 222.

A dirty fluid stream (with coarse dirt filtered out) flows through the filter basket 84. The corresponding air stream then only contains finer dirt particles that are allowed to pass through the mesh. If the dirty fluid stream 220 contains liquid, then it also contains liquid.

Filtering at the second filter device 84 (the filter basket 84) produces 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 allowed to pass through the second filter device 84. The first filter device 80 then ensures fine dust filtration to protect the blower motor.

The stream 226 is dry in comparison to a stream 228, which is guided through the window 174 on the annular wall 194 into the receiving space 90 of the container 76. The annular wall 194 also has the function of a type of drip tray for targeted guidance, in particular of a liquid-laden dirty fluid stream.

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

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.

This also achieves a separator function. The second filter device 84 separates coarse dirt. A separation of liquid (which may be contaminated) is also achieved, which then flows down the ring wall 194 into the receiving space 90.

A comparatively dry stream 226 is fed to the first filter device 80.

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

The cover device 78 is a type of fluid communication center of the separator-container device 58. It couples the original dirty fluid flow completely into the filter basket 84, and it also ensures that a cleaned air flow is coupled out at the first filter device 80, i.e. for the direct connection to the blower device 46.

The flow tube 102 is arranged outside the receiving space 90. This results in a large “interference-free” volume for receiving particularly liquid-containing dirty fluid.

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

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

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

A negative pressure is applied to the filter basket 84 via the suction flow. This frees the coarse dirt separated there from liquid. A type of rinsing of the filter basket 84 takes place.

This negative pressure on the filter basket 84 causes the coarse dirt that accumulates there to dry. Finer dirt particles can bind in 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 and in particular coarse dirt.

In the solution according to the invention, coarse dirt remains in a defined place, namely in the filter basket 84.

The container 76 can be easily rinsed and cleaned since the flow tube 102 is outside the receiving space 90.

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

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

The separator container device 58 can be operated largely independently of position (relative to the angle β). The effective separation between liquid and air and the splash protection via the splash protection device 180 can effectively prevent liquid from escaping at the outlet device 136.

The anti-slosh strips 182, 184 form anti-slosh ribs which hold back liquid and ensure that it cannot get close to the air flow area (the flow 226). Furthermore, the anti-slosh plate 212 and the ring wall 194 provide such effective anti-slosh protection.

This allows, for example, the angle β of 90° to be used as a parking position and of 0° when operating the floor cleaning machine 10 as an under-run position for furniture and the like.

Furthermore, the separator container device 58 can then also be emptied in a simple manner. In particular, dirty water and coarse dirt can be emptied separately. To empty the dirty water, the cover device 78 is removed and, without having to remove the basket holder 82, dirty liquid in the receiving space 90 can be emptied via the passage openings 162a, 162b. This is achieved by tilting the container 76.

Coarse dirt can be removed by removing the filter basket 84 and emptying it.

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

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

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 space 90.

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 basically possible, as in 11 schematically shown that a corresponding flow pipe 230 is part of a cleaning machine 232 and in particular is firmly connected to it. 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.

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.

The mode of operation is basically the same as described above for the separator container device 58.

In a further embodiment of a separator-container device 238, which in 12 As shown schematically, a flow tube 240 is firmly 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', in particular for cleaning purposes.

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.

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

According to the invention, it is provided that 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 in principle an introduction without the involvement of the cover device 78 is also possible.

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

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.

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.

As mentioned above, this has the effect that a relatively dry (contaminated) air flow is coupled out, in particular via the cover device 78.

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.
