Description

The present invention relates to a suction hose for a cleaning device, in particular for a spray extraction device, the suction hose comprising a first suction hose end and a second suction hose end, the second suction hose end being fluidly connectable to a suction port of the cleaning device, the suction hose having a spray hose with a first spray hose end and a second spray hose end and wherein the second spray hose end can be fluidly connected to a fluid connection of the cleaning device.

The present invention further relates to a nozzle attachment for a suction nozzle of a cleaning device, in particular for a spray extraction device, which suction nozzle comprises a handpiece and the nozzle attachment.

The present invention relates to a cleaning device, in particular in the form of a portable cleaning device, comprising a suction device, a suction connection which is fluidly connected to the suction device, and a suction hose which is connected or can be connected to the suction connection.

Such cleaning devices are known in different embodiments. For example, they are used in the form of spray extraction devices, in particular with suction hoses and nozzle attachments of the type described above.

A particular problem with such cleaning devices is their handling. In particular, suction hoses of the type mentioned at the beginning can twist with the spray hose in such a way that their handling is often difficult for a user.

It is therefore an object of the present invention to improve a suction hose, a nozzle attachment and a cleaning device of the type described above so that they are easier to handle.

This object is achieved according to the invention in a suction hose of the type described at the outset in that the first suction hose end is connected or can be connected to a suction nozzle, and the suction nozzle and the first suction hose end are designed to be rotatable relative to one another.

Such a design enables improved handling, particularly when used with a spray extraction device. Due to the proposed development, the entire suction hose does not have to be rotated if the suction nozzle is to be rotated, but it is sufficient for a user if he only rotates the suction nozzle relative to the suction hose, in particular relative to the first suction hose end. In particular, if the suction hose includes a spray hose for the cleaning fluid to be dispensed, undesirable twisting and thus clamping of the suction hose and/or the spray hose can be avoided.

It is advantageous if the suction nozzle and the first suction hose end can be rotated in a connection area about a connection area longitudinal axis defined by the connection area. In this way, handling of the suction hose can be improved.

The handling of the suction hose and the cleaning device can be improved in particular if the spray hose is surrounded by the suction hose. For example, it can be arranged or positioned inside the suction hose and extend over the entire length of the suction hose or beyond. However, it can also be advantageous if the spray hose is arranged or formed on the outside of the suction hose. For example, it can be detachably connected to the suction hose so that it can be removed or replaced, for example when it is not needed or if it is damaged.

The suction hose and the cleaning device can be designed simply and cost-effectively if the spray hose is designed separately from the suction hose and if the spray hose and the suction hose are arranged or designed to be rotatable relative to one another. This makes it possible in particular to replace a damaged suction hose without having to replace the spray hose if it is still fully functional. Conversely, this is also possible if the spray hose is damaged. The intended twistability of the spray hose and suction hose can in particular prevent the spray hose and the suction hose from twisting in an undesirable manner. This prevents the suction hose and/or spray hose from becoming disconnected.

It is advantageous if the suction nozzle comprises a handpiece and at least one nozzle attachment and if the handpiece and the suction hose can be rotated relative to one another. Such a configuration in particular enables a user to move and rotate the handpiece as required to complete a cleaning task. The suction hose must be However, it does not rotate and can remain in its position or rotational position. This requires the user to use less force when cleaning. This improves handling of the suction hose. The handpiece can in particular be permanently connected to a nozzle attachment or can be designed in one piece, in particular monolithically, with a nozzle attachment.

It is advantageous if the handpiece and the at least one nozzle attachment are designed to be detachably connectable to one another. Such a configuration makes it possible, in particular, to keep the handpiece permanently connected to the first suction hose end and to simply couple different nozzle attachments to the handpiece for different cleaning tasks.

The handpiece and the at least one nozzle attachment can be coupled to one another in a simple manner if the suction nozzle comprises a suction nozzle connecting device for non-positively and/or positively connecting the handpiece and the at least one nozzle attachment in a suction nozzle connecting position.

The suction nozzle can be designed easily and cost-effectively if the suction nozzle connecting device is designed in the form of a latching or snap-connecting device.

For handling the suction nozzle, it is advantageous if the suction nozzle connecting device comprises first and second suction nozzle connecting elements, which are arranged or formed on the handpiece on the one hand and on the other hand on at least one nozzle attachment, and if the first and second suction nozzle connecting elements are force-fitting and/or form-fitting in the suction nozzle connecting position Engage and are completely separated from each other in a suction nozzle separation position. The first and second suction nozzle connecting elements can be designed, for example, in the form of cooperating latching or snap-in connecting elements, for example in the form of a latching recess formed on the handpiece and a latching lug on at least one nozzle attachment that is movable relative to this.

The at least one nozzle attachment advantageously comprises a nozzle attachment suction channel and a nozzle attachment spray channel. Such a nozzle attachment can advantageously be used in conjunction with a spray extraction device. The suction nozzle can not only pick up dirt through the nozzle attachment suction channel, but also release cleaning fluid through the nozzle attachment spray channel.

A particularly compact structure of the at least one nozzle attachment can be achieved in particular if the nozzle attachment spray channel is arranged or formed within the nozzle attachment suction channel or is surrounded by the nozzle attachment suction channel.

In order to be able to dispense cleaning fluid in a simple and defined manner, it is advantageous if the nozzle attachment spray channel comprises a first nozzle attachment spray channel end and a second nozzle attachment spray channel end and if a nozzle attachment spray channel outlet is arranged or formed on the first nozzle attachment spray channel.

In order to be able to apply the cleaning fluid as finely and over a large area as possible, it is advantageous if a spray nozzle is arranged or designed on the nozzle attachment spray channel. This can be arranged, for example, at one of the two ends of the nozzle attachment spray channel or between them.

It is advantageous if the spray nozzle is arranged or designed between the first nozzle attachment spray channel end and the second nozzle attachment spray channel end. In particular, a spray mist of cleaning fluid that emerges through the spray nozzle can be limited by a section of the nozzle attachment spray channel. This can, for example, prevent an undefined application of the cleaning fluid.

The suction nozzle can be made simple and compact if the spray nozzle forms the nozzle attachment spray channel outlet.

The at least one nozzle attachment can be designed to be particularly cost-effective and compact if the spray nozzle is integrally formed, in particular monolithically, onto the nozzle attachment. In particular, it is possible to design the nozzle attachment as a plastic injection molded part, in one operation. This eliminates the need to mount the spray nozzle on the nozzle attachment.

The spray nozzle can be designed in a simple manner in the form of a cross-sectional narrowing on the nozzle attachment spray channel. In particular, it can be designed as a cross-sectional narrowing at the first nozzle attachment spray channel end.

It is advantageous if the nozzle attachment suction channel comprises a first nozzle attachment suction channel end and a second nozzle attachment suction channel end and if a nozzle attachment suction channel cross section of the nozzle attachment suction channel increases continuously starting from the first nozzle attachment suction channel end to the second nozzle attachment suction channel end. This configuration makes it possible in particular special, the nozzle attachment suction channel as an injection molded part. In addition, the speed of the suction flow at the first nozzle attachment suction channel end can be higher than at the second nozzle attachment suction channel end, so that dirt can be sucked up particularly easily with the nozzle attachment.

Preferably, a nozzle attachment spray channel cross section of the nozzle attachment spray channel decreases continuously starting from the first nozzle attachment spray channel end to the spray nozzle and continuously increases from the spray nozzle to the second nozzle attachment spray channel end. This configuration of the nozzle attachment spray channel makes it possible, in particular, to form it by injection molding in one operation.

It is advantageous for the at least one nozzle attachment to be designed in the form of one of the nozzle attachments described below. The suction hose as a whole then also has the advantages described in connection with preferred embodiments of nozzle attachments.

In order to simplify assembly of the suction hose and the cleaning device, it is advantageous if the first spray hose end projects into the handpiece and is designed to protrude beyond the first suction hose end.

In order to be able to realize a stable, fluid-tight connection between the spray hose and the handpiece, it is advantageous if the first spray hose end is held non-rotatably on the handpiece.

Furthermore, it is advantageous if the handpiece comprises a handpiece spray channel, if the handpiece spray channel comprises a first handpiece spray channel end and a second handpiece spray channel end and if a valve device is arranged or designed between the first handpiece spray channel end and the second handpiece spray channel end for opening and closing the handpiece spray channel. This configuration enables a user, in particular, to dispense cleaning fluid with the suction nozzle in a simple manner. To do this, he simply has to operate the valve device to open the handpiece spray channel.

For handling the cleaning device, it is advantageous if the valve device comprises an actuating element for actuating the valve device. For example, a user can operate the valve device with a finger, which interacts with the actuating element. The actuating element can be arranged in particular in relation to a longitudinal axis of the handpiece in a diametrically opposite direction to one of the suction nozzle connecting elements on the handpiece. In this way, it can be prevented that when the actuating element is actuated, the suction nozzle connecting element is unintentionally actuated and the suction nozzle attachment is detached from the handpiece.

The actuating element is preferably designed in the form of a pivoting lever which is pivotably mounted on the handpiece. Such a pivoting lever can be implemented in a simple manner and can also interact directly with a valve member of the valve device.

It is advantageous if the valve device comprises a biasing element for holding the valve device in a basic position in which the handpiece spray channel is closed. This configuration makes it possible, in particular, to dispense cleaning fluid only as a result of an actuation of the valve device. The valve device can be designed in a simple manner if the biasing element is designed in the form of a compression spring. This can be designed, for example, in the form of a coil spring or a leaf spring.

It is advantageous if the prestressing element holds a valve member of the valve device under prestress in a closed position. In this way, it can be ensured in particular that the nozzle attachment spray channel remains defined and reliably closed in the closed position.

It is advantageous if the actuating member is designed to cooperate with the valve member in order to move the valve member against the effect of the prestressing element from the closed position into an open position deflected from the closed position. This can be achieved, for example, if the actuating element on the handpiece is pivoted and thereby moves the valve member in the manner described.

Preferably, the second nozzle attachment spray channel end and the first handpiece spray channel end are sealed relative to one another in the suction nozzle connection position. In this way, it can be achieved in particular that the cleaning fluid can only emerge at the first nozzle attachment spray channel end and not where the second nozzle attachment spray channel end and the first handpiece spray channel end engage with one another.

According to a further preferred embodiment, it can be provided that the handpiece comprises a handpiece suction channel, that the handpiece suction channel comprises a first handpiece suction channel end and a second handpiece suction channel end and that the second nozzle attachment suction channel nal end and the first handpiece suction channel end are sealed relative to one another in the suction nozzle connection position. This configuration has the particular advantage that dirt or a dirty liquid cannot escape where the second nozzle attachment suction channel end and the first handpiece suction channel end engage with one another.

Preferably, the at least one nozzle attachment and the handpiece are sealed relative to one another in the suction nozzle connection position. In this way, a cleaning effect of the cleaning device can be improved, since dirt or a dirty liquid cannot escape in a transition area between the at least one nozzle attachment and the handpiece.

The task set at the beginning is further achieved according to the invention in a nozzle attachment of the type described above in that the nozzle attachment is designed in one piece, in particular monolithically.

In this way, the nozzle attachment can be designed in a simple and cost-effective manner. The at least one nozzle attachment can be designed, for example, in the form of a narrow crevice nozzle. In particular, it can also be formed by injection molding in one work step.

The at least one nozzle attachment advantageously comprises a nozzle attachment suction channel and a nozzle attachment spray channel. Such a nozzle attachment can advantageously be used in conjunction with a spray extraction device. The suction nozzle can not only pick up dirt through the nozzle attachment suction channel, but also release cleaning fluid through the nozzle attachment spray channel.

A particularly compact structure of the at least one nozzle attachment can be achieved in particular if the nozzle attachment spray channel is arranged or formed within the nozzle attachment suction channel or is surrounded by the nozzle attachment suction channel.

In order to be able to dispense cleaning fluid in a simple and defined manner, it is advantageous if the nozzle attachment spray channel comprises a first nozzle attachment spray channel end and a second nozzle attachment spray channel end and if a nozzle attachment spray channel outlet is arranged or formed on the first nozzle attachment spray channel.

In order to be able to apply the cleaning fluid as finely and over a large area as possible, it is advantageous if a spray nozzle is arranged or designed on the nozzle attachment spray channel. This can be arranged, for example, at one of the two ends of the nozzle attachment spray channel or between them.

It is advantageous if the spray nozzle is arranged or designed between the first nozzle attachment spray channel end and the second nozzle attachment spray channel end. In particular, a spray mist of cleaning fluid that emerges through the spray nozzle can be limited by a section of the nozzle attachment spray channel. This can, for example, prevent an undefined application of the cleaning fluid.

The suction nozzle can be made simple and compact if the spray nozzle forms the nozzle attachment spray channel outlet.

The at least one nozzle attachment can be designed to be particularly cost-effective and compact if the spray nozzle is integrally formed, in particular monolithically, onto the nozzle attachment. In particular, it is possible to design the nozzle attachment as a plastic injection molded part, in one operation. This eliminates the need to mount the spray nozzle on the nozzle attachment.

The spray nozzle can be designed in a simple manner in the form of a cross-sectional narrowing on the nozzle attachment spray channel. In particular, it can be designed as a cross-sectional narrowing at the first nozzle attachment spray channel end.

It is advantageous if the nozzle attachment suction channel comprises a first nozzle attachment suction channel end and a second nozzle attachment suction channel end and if a nozzle attachment suction channel cross section of the nozzle attachment suction channel increases continuously starting from the first nozzle attachment suction channel end to the second nozzle attachment suction channel end. This configuration makes it possible, in particular, to design the nozzle attachment suction channel as an injection-molded part. In addition, the speed of the suction flow at the first nozzle attachment suction channel end can be higher than at the second nozzle attachment suction channel end, so that dirt can be sucked up particularly easily with the nozzle attachment.

Preferably, a nozzle attachment spray channel cross section of the nozzle attachment spray channel decreases continuously starting from the first nozzle attachment spray channel end to the spray nozzle and continuously increases from the spray nozzle to the second nozzle attachment spray channel end. This configuration of the nozzle attachment spray channel makes it possible, in particular, to form it by injection molding in one operation.

The task set at the beginning is achieved according to the invention in a cleaning device of the type described above in that the suction hose is designed in the form of one of the preferred embodiments of a suction hose described above.

A cleaning device equipped with such a suction hose then also has the advantages described above in connection with preferred embodiments of suction hoses. In particular, such a suction hose improves the overall handling of the cleaning device.

It is advantageous if a second suction hose end of the suction hose is connected to the suction connection or can be detachably connected. Depending on the design, the suction hose can remain permanently on the cleaning device or can be replaced if necessary.

According to a further preferred embodiment, it can be provided that the cleaning device comprises a fluid dispensing device for dispensing a cleaning fluid. For example, the cleaning device can be designed as a spray extraction device, which can dispense a cleaning fluid onto a surface to be cleaned. The applied cleaning fluid can then be sucked off the surface to be cleaned using the suction device.

It is advantageous if the fluid delivery device includes the spray hose and if the spray hose includes a first spray hose end and a second spray hose end. Such a spray hose makes it possible, in particular, to convey the cleaning fluid to a location remote from the cleaning fluid container without having to move the cleaning device for this purpose.

A cleaning fluid can be dispensed in a simple manner if the fluid delivery device comprises a conveyor device. With the conveying device, the cleaning fluid can be conveyed out of the cleaning fluid container, for example via a connecting line to a handpiece with a spray nozzle that can be handled by the user.

Conveniently, the second spray hose end is fluidly connected to the conveying device. The cleaning fluid can thus be conveyed from the conveyor device to the second end of the spray hose and thus via the spray hose to the handpiece of the suction nozzle.

It is advantageous if the cleaning device comprises a fluid connection and if the second spray hose end is connected to the fluid connection in a fluid-effective manner, in particular in a fluid-tight manner. This configuration makes it possible, in particular, to convey the cleaning fluid through the fluid connection into the spray hose. Sealing the fluid connection and the second spray hose end prevents loss of cleaning fluid in the connection area.

The cleaning device can be made particularly compact if the fluid connection is surrounded by the suction connection. In particular, a suction hose can be connected to the cleaning device in which the spray hose is arranged inside the suction hose. Alternatively, it can also be advantageous if the fluid connection is arranged or formed outside the suction connection, in particular next to the suction connection. This configuration enables, in particular, simple and, if necessary, separate coupling with a suction hose, which includes an external spray hose.

In order to be able to convey the cleaning fluid into the spray hose, it is advantageous if the fluid connection is fluidly connected to the conveying device, in particular to a pressure side thereof.

According to a further preferred embodiment, it can be provided that the cleaning device is designed in the form of a spray extraction device.

It is advantageous if the cleaning device comprises a device carrier, a power supply connection and at least one collecting container, if the suction device is arranged or designed on the device carrier and is fluidly connected to the at least one collecting container, if the cleaning device, when operated as intended, is transverse, in particular vertical, device longitudinal axis extending to the direction of gravity defines that the suction device, the at least one collecting container and the at least one energy supply connection are arranged or positioned along the device longitudinal axis or substantially along the device longitudinal axis in such a way that the at least one collecting container is arranged on the device carrier between the suction device and the at least one energy supply connection is. This means the cleaning device can be carried easily and comfortably. Due to the special arrangement of the suction device, collecting container and energy supply connection on the device carrier, it is possible in particular to specify a center of gravity of the cleaning device as centrally as possible, i.e. in the middle. Ideally, the center of gravity is in the area of at least one collection area holder, so that the position of the center of gravity does not change or only changes slightly when the collecting container is filled. Such a design makes it possible, particularly in the case of portable cleaning devices, to lift them with little effort, since they are very well balanced due to the proposed arrangement of their components.

Preferably, the power supply connection comprises an interface for detachably connecting to a battery. This makes it possible, in particular, to design the cleaning device in the form of a battery-operated cleaning device, so that it can be operated independently of the mains.

It is advantageous if the interface includes a battery holder for non-positive and/or positive connection to a battery housing of the battery. In particular, the battery receptacle can be arranged or designed in such a way that the battery can be inserted into the battery receptacle in the direction of gravity, for example coming from above. There is no need for an additional fuse for the battery on the cleaning device if it is parked on a flat or essentially flat surface.

The interface is advantageously designed to electrically conductively connect electrical components of the cleaning device to battery poles of the battery. This can in particular be the suction device or a control device of the cleaning device or even a switching device to activate or deactivate the suction device. If the cleaning device optionally includes a conveyor device, for example a pump, the interface is also directly or indirectly electrically conductively connected to the conveyor device in order to be able to supply it with electrical energy.

It is advantageous if the power supply connection includes a connection device for connecting the cleaning device to a power grid. The connection device can in particular comprise a connection cable in order to connect the cleaning device directly to a power network. However, the connection device can also include a connection socket in order to be selectively engaged with a connection cable. For example, the cleaning device can be used either battery-operated or mains-operated.

According to a further preferred embodiment, it can be provided, in particular also in a cleaning device of the type described above, that the device carrier comprises a container receptacle and that the container receptacle is designed to accommodate the at least one collecting container in an operational state of the cleaning device. This configuration makes it possible, in particular, to arrange the at least one collecting container on the cleaning device in a defined manner in order to operate the cleaning device. In particular, dirt can be conveyed into the at least one collecting container using the suction device.

It is advantageous if the cleaning device defines a front and a back and if the suction device is arranged or designed in a front device carrier section comprising the front and if the power supply connection is arranged or designed on a rear device carrier section comprising the back. This configuration enables, in particular, optimal balancing of the cleaning device. Arranging the suction device in the front equipment support section makes it possible, in particular, to provide a suction connection in this area, which can be connected to a suction hose. In order to balance the weight of the suction device, the arrangement of the energy supply connection on the rear device carrier section is favorable, since, for example, a battery coupled to the energy supply connection can form a counterweight to the suction device.

Preferably, the container receptacle is arranged or formed on a central device carrier section and the middle device carrier section is arranged or formed between the front and rear device carrier sections. Arranging or designing the container receptacle in the proposed manner makes it possible, in particular, to specify the center of gravity of the cleaning device on the central device support section. The position of the center of gravity does not change or changes only insignificantly when the container holder is loaded with cleaning items or a dirty liquid.

It is advantageous if the fluid delivery device comprises a cleaning fluid container. The cleaning fluid required for cleaning can then be filled into this cleaning fluid container and dispensed using the fluid delivery device of the cleaning device. The cleaning fluid can in particular be water or a mixture of water and a cleaning agent.

A particularly compact design of the cleaning device can be achieved if the conveyor device is arranged or designed in the front device support section. In particular, it can be used together with the suction device in the front Device carrier section can be arranged or designed.

A cleaning fluid can be conveyed in a simple manner if the conveying device is designed in the form of a pump.

The cleaning device can be implemented easily and cost-effectively if the pump is designed in the form of a membrane pump or in the form of a piston pump. For example, a membrane pump can be operated permanently, even when delivery of cleaning fluid is prevented, in particular by a valve device on a handpiece with a spray nozzle that can be handled by the user.

Conveniently, the cleaning device, in particular a cleaning device of the type described above, comprises a suction connection arranged or formed on the device carrier for connection to a suction hose. Such a suction connection makes it possible, in particular, to convey dirt or a dirt liquid with the suction hose through the suction connection into the cleaning device, in particular into the at least one collecting container.

The cleaning device is particularly easy to handle if the suction connection is arranged or designed on the front device support section. In particular, it can be arranged or designed on the front of the cleaning device.

Alternatively, the suction hose can also be permanently connected to the suction connection.

It is advantageous if the cleaning device, in particular a cleaning device of the type described above, comprises a suction hose, if the suction hose comprises a first suction hose end and a second suction hose end and if the second suction hose end is fluidly connected or connectable to the suction device. This configuration makes it possible, in particular, to pick up dirt with the first end of the suction hose during operation of the cleaning device and to convey it through the suction hose to the suction device.

The cleaning device can be handled in a simple manner if the second end of the suction hose is connected to the suction connection or can be detachably connected.

In order to pick up dirt in a simple and defined manner, it is advantageous if the first suction hose end is connected or can be detachably connected to a suction nozzle. In particular, different types of suction nozzles can be provided in order to be able to optimally solve different cleaning tasks. For example, suction nozzles can be designed in the form of surface suction nozzles, upholstery suction nozzles or joint suction nozzles.

Preferably, the first spray hose end is connected in a fluid-tight manner to the second handpiece spray channel end. This means that the cleaning fluid can be directed through the spray hose into the handpiece spray channel without any losses.

It is advantageous if the fluid connection is arranged or designed on the front device support section, in particular on the front of the cleaning device.

In order to avoid twisting of the spray hose, which is particularly disadvantageous if the spray hose is guided on, in particular in, the suction hose, it is advantageous if the second spray hose end is held rotatably on the cleaning device, in particular rotatable relative to the fluid connection about a fluid connection longitudinal axis defined by the latter is held. The second spray hose end can thus rotate relative to the fluid connection if, for example, the first spray hose end is twisted, for example by rotating the handpiece relative to the first suction hose end in the manner described above.

For the handling of the cleaning device, it is also advantageous if the center of gravity of the cleaning device, in particular regardless of whether the at least one collecting container and/or the cleaning fluid container is filled as intended, lies in the area of the container holder, in particular in the middle device support section. In this way, the cleaning device can be optimally balanced. For example, this can be achieved by a correspondingly balanced arrangement of the components of the cleaning device in the front and rear device support sections.

According to a further preferred embodiment, it can be provided that the at least one collecting container is designed in the form of a dirty water container and that the dirty water container and the cleaning fluid container are arranged together in the container receptacle in a spray extraction working position of the cleaning device. This configuration makes it possible, in particular, to use the cleaning device as a spray extraction device. The container holder therefore serves in particular to hold both the cleaning fluid container and the dirty water container. This configuration has the particular advantage that there is a focus The position of the cleaning device changes only slightly when the cleaning fluid is dispensed with the cleaning device and picked up again and then fills the dirty water container. During operation of the cleaning device, the center of gravity then gradually moves in a direction from the cleaning fluid container to the dirty water container.

Furthermore, it is favorable if the at least one collecting container is designed in the form of a suction container and is arranged in the container receptacle in a suction working position of the cleaning device. Such a suction container can in particular completely or essentially completely fill the container receptacle. For example, in a modular cleaning device, it can be inserted into the container holder as an alternative to the dirty water container and the cleaning fluid container. With such a suction container, the cleaning device can only be used for vacuuming, so that the cleaning device can take on the function of a wet/dry vacuum cleaner.

It is advantageous if the suction container defines a suction container volume, if the dirty water container defines a dirty water container volume, if the cleaning fluid container defines a cleaning fluid container volume and if the suction container volume corresponds approximately to the sum of the dirty water container volume and the cleaning fluid container volume. Such a configuration makes it possible, in particular, to optimally use the installation space specified by the container receptacle with the suction container. This means that when the cleaning device is operated as a pure suction device, the suction container volume can be maximized.

In order in particular to design the cleaning device in such a way that, when operating as a spray extraction device, it enables the entire cleaning fluid contained in the cleaning fluid container to be safely and reliably picked up after it has been dispensed, it is advantageous if the cleaning fluid container volume corresponds to a maximum of approximately 50% of the dirty water container volume. Such a size ratio makes it possible, in particular, to arrange or design a separating device in the dirty water container for separating liquid and solid dirty liquor components from a dirty liquor stream.

So that the cleaning fluid cannot escape from the cleaning fluid container in an undesirable manner, it is advantageous if the cleaning fluid container comprises a cleaning fluid container lid for closing the cleaning fluid container.

In order to be able to easily fill the cleaning fluid container with a cleaning fluid, for example water, without having to remove the cleaning fluid container lid, it is advantageous if a filling opening is arranged or formed on the cleaning fluid container lid.

The cleaning fluid container preferably comprises a closure element for closing the filling opening. This can prevent cleaning fluid from escaping undesirably through the filling opening. The closure element can, for example, be arranged on the cleaning fluid container in a movable or deformable manner, in particular pivotable, in order to be moved or deformed from a position in which the filling opening is open to a position in which the filling opening is closed and vice versa.

Furthermore, it is advantageous if the insertion opening has a size and a filling opening cross section which corresponds or essentially corresponds to a size and a shape of the at least one nozzle attachment, in particular of the monolithically designed nozzle attachment. Such a configuration makes it possible, in particular, to guide the at least one nozzle attachment through the filling opening into the cleaning fluid container. In this way, the suction hose can be flushed directly with the cleaning fluid and cleaned in this way. Furthermore, cleaning fluid for cleaning the cleaning fluid container with the suction nozzle can be dispensed through the at least one nozzle attachment.

Cleaning fluid can be removed from the cleaning fluid container in a simple manner if it has a container outlet which is fluidly connected to the conveyor device, in particular to a suction side of the same.

Preferably, the container outlet is arranged or formed on a cleaning fluid container bottom. The gravity acting on the cleaning fluid can thus be used to force the cleaning fluid through the container outlet. In this way, the performance of a conveyor device for the cleaning fluid can be provided to a minimum.

So that cleaning fluid can only emerge from the cleaning fluid container when this is desired, it is advantageous if an outlet valve, in particular in the form of a ball valve, is arranged or designed at the container outlet, and if the outlet valve is closed when the cleaning fluid container releases the container receptacle, and when the outlet valve is open when the cleaning fluid container is properly accommodated in the container receptacle.

Preferably, a connecting piece is arranged on the container receptacle or designed for fluid-tight coupling to the container outlet when the cleaning fluid container is accommodated in the container receptacle as intended. In particular, the connecting piece can be arranged or designed on a bottom of the container receptacle, whereby optimal interaction with a container outlet arranged accordingly on the cleaning fluid container is possible.

To improve the handling of the cleaning device, it is advantageous if the connecting piece comprises a valve actuating member for opening the outlet valve when the cleaning fluid container is properly accommodated in the container receptacle. The valve actuating member can be designed, for example, in the form of a protruding pin, which, for example in the case of a ball valve, moves the ball into a deflected position against the effect of a prestressing element when the cleaning fluid container is inserted into the cleaning receptacle.

The cleaning fluid can be conveyed into the spray hose in particular in a simple manner if the connecting piece is fluidly connected to the conveying device. For example, the conveyor device can suck the cleaning fluid out of the cleaning fluid container.

In order to be able to insert the cleaning fluid container into the container receptacle in a defined manner, it is advantageous if at least one spacer, in particular several, is arranged or formed on the cleaning fluid container, which is supported on a rear partition wall of the rear device carrier section which delimits the container receptacle. In particular, the cleaning fluid container can be used to press the dirty water container in a defined manner against the equipment carrier, in particular to seal a dirty water container inlet of the dirty water container relative to one another against a dirty water outlet on the container receptacle of the device carrier.

Preferably, the rear partition and a cleaning fluid container wall of the cleaning fluid container comprising the at least one spacer are inclined towards one another by an angle of inclination. This configuration particularly facilitates the insertion of the cleaning fluid container into the container receptacle. In particular, it can have a wedge-shaped contour, which makes it easier to insert it into the container holder when the dirty water container is already inserted.

Preferably, a value of the angle of inclination is in a range from approximately 1° to approximately 5°. The cleaning fluid container can have the shape of a flat wedge and can be easily inserted between the rear partition and a dirty water container that has already been placed in the container holder.

It is advantageous if a cleaning fluid container wall of the cleaning fluid container pointing in the direction of the front housing support section and a dirty water container wall of the dirty water container pointing in the direction of the rear housing support section lie against one another in the spray extraction working position, in particular flatly. This configuration has the particular advantage that, for example, the dirty water container can be pressed above the cleaning fluid container in the direction of the front housing support section. For example, appropriate connections for receiving a dirty water solution in the dirty water container can be provided on this. The proposed development thus enables optimal sealing of the dirty water container relative to these connections, which will be explained in more detail below.

In order to be able to convey the dirty water into the dirty water container, it is advantageous if the dirty water container has a dirty water container inlet which is fluidly connected to the suction connection.

It is advantageous if a dirty water outlet is formed on the container receptacle, which is fluidly connected to the suction connection, and if the dirty water outlet is fluidly and fluid-tightly connected to the dirty water container inlet in the spray extraction working position. In this way, the dirty liquor that is directed to the suction hose connection, for example through the suction hose, can be introduced into the dirty water container.

In order to prevent the dirty water from escaping in the transition area between the dirty water outlet and the dirty water container inlet, it is advantageous if a sealing element is arranged or designed at the dirty water outlet to seal the dirty water outlet and the dirty water container inlet relative to one another. The sealing element can, for example, be molded onto the device carrier, for example made of a thermoplastic elastomer.

The dirty water container preferably comprises an air outlet which is fluidly connected to the sauna device. In this way In particular, the dirty water can be sucked into the dirty water container and liquid and solid components can be separated in the dirty water container, so that only gaseous components of the dirty water, i.e. a gaseous dirty water component, can be sucked in with the suction device.

Furthermore, it is advantageous if an air inlet is arranged or formed on the container receptacle, which is fluidly connected to the suction device, and if the air outlet is fluidly and fluid-tightly connected to the air inlet in the spray extraction working position. In particular, a gaseous component of the sucked-in dirty liquor can be passed through the air outlet out of the dirty water container and through the air inlet to the suction device without losses.

Here too, it is advantageous if a sealing element is arranged or designed at the air inlet to seal the air inlet and the air outlet relative to one another.

Preferably, the air inlet and the dirty water outlet define a plane that is slightly inclined with respect to the direction of gravity. In particular, this level can also be specified by a section of a boundary wall of the container holder, on which the air inlet and the dirty water outlet are arranged or formed. In this way, an improved sealing of the dirty water container in the container receptacle of the cleaning device can be achieved, in particular relative to the side wall of the front device support section delimiting the container receptacle.

The cleaning device can be made particularly compact if the dirty water outlet and/or the air inlet are arranged or designed on a side wall of the front device carrier section that delimits the container receptacle.

According to a further preferred embodiment, it can be provided that the dirty water outlet defines a dirty water outlet longitudinal axis, that the air inlet defines an air inlet longitudinal axis and that the dirty water outlet longitudinal axis and the air inlet longitudinal axis run parallel to one another and/or when the cleaning device is operating as intended, transversely, in particular perpendicularly, to the direction of gravity. Such a configuration makes it possible, in particular, to insert the dirty water container into the container receptacle and at the same time to bring the air outlet into engagement with the air inlet on the one hand and the dirty water outlet to engage with the dirty water container inlet in a defined manner.

The suction device can be easily implemented if it includes a fan.

Conveniently, the air defines an axis of rotation which, when operated as intended, runs parallel or essentially parallel to the direction of gravity. In particular, a space-saving arrangement of the suction device in the front equipment carrier section can be realized.

The axis of rotation advantageously runs transversely, in particular perpendicular to the longitudinal axis of the dirty water outlet and/or to the longitudinal axis of the air inlet. In particular, regardless of an orientation of the cleaning device relative to the direction of gravity, an optimal positioning of the fan in a housing of the cleaning device can be made possible.

According to a further preferred embodiment, it can further be provided that the cleaning device comprises a housing which defines a housing interior, and that a pressure-side suction device outlet of the suction device opens into the housing interior, in particular in the area of the front housing support section. This configuration makes it possible, in particular, to minimize the speed of the gas flow and then allow it to exit through appropriate openings on the housing.

For handling the cleaning device, it is particularly favorable if the cleaning device includes a switching device for activating and deactivating the suction device.

Preferably, the switching device is designed to activate and deactivate the fluid delivery device, in particular the conveying device. For this purpose, the switching device can include separate switching elements for the suction device and the fluid delivery device. However, it is also possible for only a single switching element to be provided in order to simultaneously activate and deactivate the suction device and the fluid delivery device.

Preferably, the switching device is designed to simultaneously activate and deactivate the suction device and the fluid delivery device, in particular the conveying device. A user can thus activate the cleaning device to suck and dispense a cleaning fluid by simply actuating the switching device.

In order to enable particularly easy handling of the cleaning device, it is advantageous if the switching device is arranged or designed on an upper side of the cleaning device. In particular, it can be arranged or formed on the front device carrier section.

In order to be able to immediately indicate to a user whether the cleaning device is activated or deactivated, it is advantageous if the switching device is designed in the form of a rotary or toggle switch.

According to a further preferred embodiment, it can be provided that the conveying device and the suction device are dimensioned such that a power consumption of the suction device corresponds to at least approximately five times a power consumption of the conveying device, in particular at least approximately ten times. This configuration makes it possible, in particular, to operate the conveying device permanently, even when no cleaning fluid is dispensed, because this is prevented, for example, by the valve device on the handpiece.

For easy transport of the cleaning device, it is advantageous if the cleaning device comprises a carrying handle, which is arranged or designed on the rear device carrier section and on the front device carrier section and includes a handle section which overlaps the container receptacle in a carrying position. This configuration enables an operator, in particular, to grasp the carrying handle directly above the center of gravity of the cleaning device, so that the cleaning device can be lifted and carried by the user in an optimally balanced manner.

It is advantageous if the center of gravity of the cleaning device is positioned below the handle section in the carrying position. As mentioned, the carrying comfort of the cleaning device can be improved, since the cleaning device can be grasped by a user with maximum balance on the handle section.

In order to enable a user to have direct access to the container holder, it is advantageous if the carrying handle can be pivoted about a handle pivot axis which runs transversely, in particular perpendicularly, to the direction of gravity when the cleaning device is being operated as intended. For example, it can be pivoted from a carrying position in which it grips over the container receptacle into a storage or operating position in which it releases the container receptacle.

Preferably, in an operating position of the cleaning device, the handle section completely releases the container receptacle and is positioned laterally on the central device support section. In this way, the containers of the cleaning device can be easily inserted into the container holder and removed from it again.

Furthermore, in a further preferred embodiment of the cleaning device, in particular also in a cleaning device of the type described above, it can be provided that the cleaning device comprises a separating device for separating a liquid dirty liquor component into the at least one collecting container from a dirty fluid stream comprising the liquid and a gaseous dirty liquor component. The separating device in particular prevents liquid from getting into the suction device and damaging it.

A particularly compact design of the cleaning device can be achieved in particular in that the separating device is arranged or designed in at least one collecting container.

In order to achieve an efficient separation between liquid and gaseous dirty liquor components, it is advantageous if the separating device is arranged or designed on at least one collecting container between the dirty water container inlet and the air outlet.

So that the liquid dirt liquor component contained in the collecting container cannot escape from the collecting container in an undesirable manner, it is advantageous if the at least one collecting container comprises a removable collecting container lid. In particular, this can be designed in the form of a dirty water container lid if the collecting container is designed in the form of the dirty water container.

It is advantageous if the separating device comprises a separating insert which is inserted into the dirty water container and closed by the dirty water container lid. In particular, the separator insert can be removed from the dirty water container and separated from the dirty water container lid, so that the cleaning device and its components can be cleaned in a simple manner.

The separation device preferably comprises a first separation stage which is connected downstream of the dirty water tank inlet. In a first separation step, liquid and gaseous dirt liquor components in particular can be separated from one another.

In order to achieve an even better separation between liquid and gaseous dirt liquor components, it is advantageous if the separation device comprises a second separation stage, which is connected downstream of the first separation stage.

It is advantageous if the first separation stage comprises a deflection element for deflecting the dirty fluid flow flowing into the dirty water container in a direction opposite or essentially against the direction of gravity when the cleaning device is operated as intended. In this way, a first, simple separation between liquid and gaseous dirty liquor components can be achieved by using gravity to separate them. In particular, the dirty fluid flow can be deflected by a deflection angle of approximately 90°.

Conveniently, a drip opening is formed on the deflection element in the direction of gravity to drain the liquid dirty liquor component into the dirty water container. In particular, it can be prevented that the liquid dirty liquor component flows back through the dirty water tank inlet into the dirty water outlet.

In order to reduce in particular a flow velocity of the gaseous dirt liquor component, it is advantageous if a flow cross section expands after the deflection element.

It is advantageous if the first separation stage comprises a deflection bell, which is connected downstream of the deflection element and is open in the direction of gravity, for redirecting the dirty fluid flow, in particular the gaseous dirty liquor component, in the direction of gravity into the dirty water container. In this way, the dirty fluid flow can be redirected by an additional 180° after the deflection element by the deflection bell, with the liquid and gaseous dirty liquor components separating from one another. Together with the deflection element, the dirty fluid flow can be deflected by a total of 270°, for example by three rectangular deflections connected downstream.

A compact design of the cleaning device can be achieved in particular in that the dirty water container lid includes the deflection bell. For example, the dirty water container lid and the deflection bell can be designed in one piece, in particular monolithically.

According to a further preferred embodiment, it can be provided that the second separation stage comprises a flow space for the gaseous dirty liquor component arranged above a collecting space of the dirty water container with a flow space inlet, which fluidly connects the collecting space and the flow space, and a flow space outlet, which is fluidly connected to the suction device . The configuration described makes it possible, in particular, to arrange the flow space above the collecting space of the dirty water container, so that a gaseous dirty liquor component can be guided into the flow space via the collecting space after being introduced into the collecting space through the flow space inlet and then passed through the flow space outlet to the suction device.

In order to prevent liquid dirt fin components from penetrating the flow space, it is advantageous if the flow space inlet is closed with a separating element which is designed to be gas-permeable and liquid-impermeable.

A separation of liquid and gaseous dirt liquor components can be achieved in a particularly simple manner if the separating element is formed by a fleece.

In order to achieve the lowest possible flow velocity of the gaseous dirt liquor component through the flow inlet, it is advantageous if the separating element is curved convexly into the flow space against the direction of gravity. In this way, a passage opening of the flow space inlet can be realized as large as possible.

Preferably, a cross section of the flow space inlet is larger than a cross section of the deflection bell. The flow speed in the area of the flow space inlet is lower than in the area of the deflection bell. In this way, a separation between liquid and gaseous dirty liquor components is particularly promoted.

Furthermore, it is advantageous if the flow space outlet is open in the direction of gravity and opens into an upper end of a float shaft extending in the direction of gravity.

Conveniently, a lower end of the float shaft in the direction of gravity is fluidly connected to the collecting space. This makes it possible in particular for the liquid dirt liquor component to flow into the from the lower end Flow through the float shaft and can fill it accordingly as the level in the collecting space increases. In this way, the liquid dirt liquor component in the float shaft also seals the lower and upper ends of the float shaft from one another.

In order to prevent coarse dirt from penetrating the float shaft, it is advantageous if a fluid-permeable filter element is arranged or formed at the lower end of the float shaft.

The filter element can be easily formed in the form of a sieve.

In order to be able to use a filling level in the collecting space, for example to interrupt a suction flow, it is advantageous if a floating element is arranged in the float shaft and can be moved parallel and in the direction opposite to the direction of gravity. Such a floating element can, for example, be raised against the direction of gravity as a result of an increase in the fill level in the collecting space and sink again in the direction of gravity when the collecting space is emptied.

In order to prevent as much as possible that the liquid dirt component can flow past the floating element, it is advantageous if an inner contour of the float shaft corresponds or essentially corresponds to an outer contour of the floating element.

The floating element is advantageously designed in the form of a sleeve that is closed on one side and has an open end of the sleeve in the direction of gravity. Such a floating element can float in a simple and safe manner on the liquid dirt liquor component in the float shaft and move according to a fill level in the float shaft.

Furthermore, it is advantageous if a float shaft outlet which is arranged at the upper end of the float shaft and is open in the direction of gravity is fluidly connected to the air outlet. After flowing through the flow space and flowing into the upper end of the float shaft, the gaseous dirty liquor component can flow into the float shaft outlet after being redirected again by 180° and leave the dirty water tank through the air outlet. The second separation stage can thus enable a deflection of the suction flow by a total of approximately 360 °, namely by approximately 90 ° when entering through the flow space inlet into the flow space, by a further approximately 90 ° when exiting through the flow space outlet into the float shaft and also around the already mentioned approximately 180° from the float shaft into the float shaft outlet. In this way, residues of the liquid dirty liquor component can be reliably separated from the gaseous dirty liquor component.

For a compact design of the cleaning device, it is particularly advantageous if a cross section of the float shaft outlet is smaller than a cross section of the float shaft.

It is advantageous if the float shaft outlet forms a stop for the floating element when moving against the direction of gravity and if the floating element closes the float shaft outlet in an air outlet closed position when it hits the float shaft outlet. This configuration makes it possible, in particular, to use the floating element as a valve element in order to open or close the float shaft outlet, depending on a fill level of the liquid dirty water liquor in the dirty water tank. So if the floating element closes the float shaft outlet because the fill level in the dirty water tank is too high, a suction flow is interrupted. A user can notice this immediately. In other words, the cleaning device warns you that the dirty water container is full by decreasing suction power.

According to a further preferred embodiment of the cleaning device, in particular a cleaning device of the type described above, it can be provided that the cleaning device comprises a flow interruption device for interrupting a suction flow generated by the suction device in an interruption position. Such a flow interruption device can be used in particular to indicate to a user that a maximum fill level in the dirty water container has been reached and that he should empty it.

In order to interrupt a dirty fluid flow, it is advantageous if the flow interruption device comprises a valve arrangement arranged between the dirty water inlet and the air outlet.

The valve arrangement can be designed in a simple manner if it includes the floating element and the float shaft outlet. As already mentioned, the floating element can form a valve member, which closes or opens the float shaft outlet depending on the fill level.

It is advantageous if the floating element closes the float shaft outlet in the interrupted position. This interrupts a suction flow, which can be immediately noticed by a user.

In order to be able to clean the flow space, it is advantageous if the dirty water container lid closes the flow space counter to the direction of gravity. It can be removed, in particular, to clean the flow space.

Furthermore, it is favorable if the flow space is limited in the direction of gravity by a bottom of the separator insert in the dirty water container. The floor thus separates in particular the flow space and the collecting space of the dirty water container from one another.

A compact design of the separation device can be achieved in particular in that the flow space inlet is formed in the bottom of the separation insert.

In order to particularly improve handling of the cleaning device, for example when cleaning it, it is advantageous if the float shaft comprises an upper shaft section which is arranged or formed on the bottom of the separator insert. This makes it possible, for example, to easily remove the float shaft, in particular the upper shaft section, when removing the separator insert from the dirty water container.

Preferably, the float shaft comprises a lower shaft section, which adjoins the upper shaft section in the direction of gravity. The float shaft is therefore formed by the upper and lower shaft sections together.

For cleaning the cleaning device, it is advantageous if the upper and lower shaft sections are designed to be detachably connectable to one another.

According to a further preferred embodiment of the cleaning container, in particular also in a cleaning container of the type described above, it can be provided that the at least one collecting container comprises a collecting container securing device for securing the collecting container lid on the at least one collecting container in a closed position. The collecting container securing device can in particular be provided both on the dirty water container and on the suction container in order to secure their respective lids on the said container.

It is advantageous, particularly in the case of a cleaning container of the type described above, if the cleaning fluid container comprises a cleaning fluid container securing device for securing the cleaning fluid container lid on the cleaning fluid container in a closed position. This means that the cleaning fluid container lid cannot be accidentally removed from the cleaning fluid container.

It is advantageous if the suction container comprises a suction container inlet and a suction container air outlet, if the suction container is connected to the dirty water outlet on the container receptacle in a fluid-effective and fluid-tight manner in a suction position and if the suction container air outlet is connected to the air inlet on the container receptacle in a fluid-effective and fluid-tight manner. This configuration makes it possible in particular to use the cleaning device with the suction container as a pure suction device, for example as a wet/dry vacuum cleaner.

In order to separate gaseous and liquid dirt liquor components from one another, it is advantageous if a first separation stage on the suction container comprises a deflection element in the form of a baffle plate pointing in the direction of the suction container outlet and arranged at a distance from it. For example, a dirty fluid stream can be deflected by approximately 90° when introduced into the suction container.

In order to achieve an even better separation between gaseous and liquid dirt liquor components, it is advantageous if a second separation stage on the suction container comprises a separation element that closes the suction container air outlet.

Liquid and gaseous dirt liquor components can be easily separated from one another if the separating element comprises a filter. This can in particular be a fleece or a net with a sufficiently small mesh size.

It is advantageous if the separating element is sleeve-shaped and comprises a sleeve wall which has at least one opening, and if the filter closes the at least one opening. In this way, it is very likely that only the gaseous dirt liquor component can pass through the opening and is directed to the suction device, but not the liquid dirt liquor component.

For a compact design of the cleaning device, it is particularly advantageous if the separating element is inserted into the suction container projects, in particular in a direction transverse, in particular perpendicular, to the direction of gravity.

To operate the cleaning device independently of a power grid, it is advantageous if it includes at least one battery.

In order to be able to charge the battery in a simple manner and, if necessary, to replace it with a charged battery when it is empty, it is advantageous if the battery can be detachably connected to the cleaning device.

The battery is preferably designed in the form of a rechargeable battery. So it can be used multiple times.

Furthermore, it can be advantageous, especially in a cleaning device of the type described above, if the cleaning device is designed to be modular and if either a single suction container on the one hand or a cleaning fluid container together with a dirty water container on the other hand or a steam generating module with a steam generating device and a fluid container can be inserted into the container receptacle is. Such a design makes it possible, in particular, to use the device carrier as a basic device and, depending on the cleaning task to be solved, to equip the cleaning device with a corresponding module. As described in detail above, spray extraction devices or suction devices can be designed. If a steam generation module, which includes a steam generation device and a fluid container, is inserted into the container receptacle, the cleaning device can also be used as a steam cleaning device.

The suction connection 56 is formed on the front 32 in the area of a recess 60, specifically in relation to the direction of gravity 28 in an upper region of the cleaning device 10. The recess 60 extends to approximately a third of a total height 62 of the cleaning device 10, starting from an upper side 64 the same.

The suction hose 58 includes a first suction hose end 66 and a second suction hose end 68. The second suction hose end 68 is designed in the form of a hose coupling 70, which is connected to the suction connection 56 in a connecting position, as exemplified in FIG 1 and 7 is shown, with the suction connection 56 engages in a force-fitting and/or positive manner. In the connection position, the hose coupling 70 is secured both axially on the suction connection 56 and against rotation relative to the suction connection 56. This is achieved in particular by a non-round outer contour of the hose coupling 70.

On the hose coupling 70, a pivotable locking member 72 is formed with a projecting locking lug 74, which in the connecting position engages in a locking recess 76 formed on the front equipment carrier section 36 on the suction connection 56.

A longitudinal axis of the suction connection 56 runs parallel to the longitudinal axis 26 of the device.

The cleaning device 10 further comprises a fluid connection 78, which is arranged or formed on the front device support section 36, namely on the front 32. It is used to connect to a spray hose 80, which includes a first spray hose end 82 and a second spray hose end 84. The spray hose 80 forms part of the fluid delivery device 44.

A nipple 86 is arranged at the second spray hose end 84 and engages in a sealed manner in the fluid connection 78.

The fluid port 78 is arranged so that it is surrounded by the suction port 56. The fluid connection 78 comprises a short sleeve-shaped section into which the nipple 86 engages.

Surrounded by the suction connection 56 is a holder 88 formed with two half-shells which surround the nipple 86 between two annular flanges 90 and 92 formed on the nipple 86. The nipple 86 and thus the second spray hose end 84 are held in the holder 88 so that they can rotate about a longitudinal axis of the nipple 86.

The fluid connection 78 is fluidly connected to the conveying device 50 via a connecting line 94, namely to a pressure side 96 of the conveying device 50. As described, the second spray hose end 84 on the cleaning device 10 is held rotatably relative to the fluid connection 78 about a fluid connection longitudinal axis 98 defined by it.

The spray hose 80 is surrounded by the suction hose 58. The spray hose 80 and the suction hose 58 are designed separately from one another in the illustrated embodiment. The suction hose 58 is provided with a spiral-shaped reinforcing rib 100 on its outside.

The dirty water container 18 and the cleaning fluid container 48 are in a spray extract The working position of the cleaning device 10 is arranged together in the container receptacle 30, as shown schematically in FIG 2 and 10 is shown.

The cleaning fluid container 48 includes a cleaning fluid container lid 102 for closing the cleaning fluid container 48. In 4 the cleaning fluid container 48 is shown schematically with the cleaning fluid container lid 102 attached.

A filling opening 104 is arranged or formed on the cleaning fluid container lid 102. Furthermore, the cleaning fluid container 48 comprises a closure element 106 for closing the filling opening 104. The closure element 106 is movably held on the cleaning fluid container lid 102 and is designed in the form of a rubber element with a protruding grip tab 108, which makes it possible to pull the closure element 106 out of the filling opening 104.

The filling opening 104 has a circular filling opening cross section.

The cleaning fluid container 48 further comprises a container outlet 110, which is fluidly connected to the conveying device 50, namely to a suction side 112 of the same.

An outlet valve 114 is arranged or formed at the container outlet 110, namely in the form of a ball valve 116. The outlet valve 114 is designed such that it is closed when the cleaning fluid container 48 releases the container receptacle 30 or is removed from it, as for example in 4 shown. The outlet valve 114, on the other hand, is open when the cleaning fluid container 48 is properly accommodated in the container receptacle 30, as shown schematically in 7 shown.

The container outlet 110 is designed to cooperate with a connecting piece 118 arranged on the container receptacle 30. It serves for fluid-tight coupling with the container outlet 110 when the cleaning fluid container 48 is accommodated in the container receptacle 30 as intended, as in particular in the enlarged view in 9 shown schematically.

A valve actuating member 120 is arranged on the connecting piece 118 for opening the outlet valve 114 when the cleaning fluid container 48 is accommodated in the container receptacle 30 as intended. The valve actuating member 120 is in the form of a protruding pin 122, which, with an end 124 pointing in the direction of the cleaning fluid container 48, presses a ball 126 out of a valve seat 128 against the action of a spring 130 when the cleaning fluid container 48 is inserted into the container receptacle 30 and the container outlet 110, which is provided with a recess corresponding to the connecting piece 118, comes into engagement with the connecting piece 110. 9 shows the exhaust valve 4 in its open position.

The connecting piece 118 is designed to be angled and is connected in a fluid-effective and sealed manner to the conveyor device 50, namely its suction side 112, via a connecting line 132.

The container receptacle 30 is limited by a rear partition 134 of the rear equipment carrier section 38. A cleaning fluid container wall 136, which faces toward the rear partition 134 when the cleaning fluid container 48 is inserted into the container receptacle 30, is inclined relative to the rear partition 134 by an angle of inclination 138. In the exemplary embodiment shown, the angle of inclination 138 has a value in a range from approximately 1° to approximately 5°.

On the outside of the rear partition 134, a plurality of spacers 140 are formed in the form of projecting projections, which rest on the rear partition 134 when the cleaning fluid container 48 is inserted and are supported on it. They serve the purpose of pressing a cleaning fluid container wall 142, which points towards the front equipment support section 36, against a dirt container wall 144 of the dirty water container 18 in the spray extraction working position. The cleaning fluid container wall 142 and the dirt container wall 144 lie flat against each other. The cleaning fluid container 48 thus prevents the dirty water container 18 from being able to move in the direction of the rear housing support section 38.

The cleaning fluid container 48 further includes a cleaning fluid container securing device 146 for securing the cleaning fluid container lid 102 on the cleaning fluid container 48 in a closed position.

The cleaning fluid container securing device 146 includes two locking tabs 148, which are designed to protrude from the cleaning fluid container lid 102 and cooperate with corresponding retaining elements on the cleaning fluid container 48 in order to couple the cleaning fluid container lid 102 to the cleaning fluid container 48 and thus prevent unintentional loosening of the friction cleaning fluid container lid 102 from cleaning fluid container 48.

The dirty water container 18 serves to hold a dirty water liquor 150, in particular a liquid dirty water liquor component 152. For this purpose, the dirty water tank 18 comprises a collecting space 154.

A dirty water tank inlet 156 is used to introduce the dirty water 150 into the dirty water container 18. It is fluidly connected to the suction connection 56. Furthermore, a dirty water outlet 158 is formed on the container receptacle 30, which is fluidly connected to the suction connection 56. In the spray extraction working position, the dirty water outlet 158 is connected to the dirty water container inlet 156 in a fluid-effective and fluid-tight manner, as shown, for example, in FIGS 7 and 10 is easy to see.

The dirty water tank inlet 156 is formed on an inclined portion of a dirty water tank wall 160. The inclined section forms an angle 162 with the direction of gravity 28, which has a value in a range from approximately 2° to approximately 8°. The section is inclined in such a way that the dirty water container 18 widens in the direction of a dirty water container lid 164 which closes the dirty water container 18.

A sealing element 166 is arranged or designed at the dirty water outlet 158 for sealing the dirty water outlet 158 and the dirty water container inlet 156 relative to one another.

The dirty water outlet 158 is connected to the suction connection 56 via a short pipe section 168. The dirty water outlet 158 defines a dirty water outlet longitudinal axis 170, which runs parallel to the device longitudinal axis 26 and perpendicular to the direction of gravity 28.

The dirty water container 18 further comprises an air outlet 172, which is fluidly connected to the suction device 14. An air inlet 174 assigned to the air outlet 172 is arranged or formed on the container receptacle 30 and is fluidly connected to the suction device 14. The air outlet 172 is connected to the air inlet 174 in a fluid-effective and fluid-tight manner in the spray extraction working position.

For sealing purposes, a sealing element 176 is arranged or formed at the air inlet 174 in order to seal the air inlet 174 and the air outlet 172 relative to one another. In the exemplary embodiment shown in the figures, the sealing elements 166 and 176 are formed in the form of molded sealing elements made of a thermoplastic elastomer.

The dirty water outlet 158 and the air inlet 174 are arranged or formed on a side wall 178 of the front equipment carrier section 36 delimiting the container receptacle 30. The air inlet 174 and the air outlet 172 are also formed on sections of the side wall 178 or the dirty water container wall 160 on sections that are inclined by the angle 162 relative to the direction of gravity 28.

The air inlet 174 defines an air inlet longitudinal axis 180. In the exemplary embodiment shown in the figures, the dirty water outlet longitudinal axis 170 and the air inlet longitudinal axis 180 run parallel to one another and also transversely, namely perpendicularly, to the direction of gravity 28 when the cleaning device 10 is operated as intended.

The device carrier 12 is designed like a housing. A front housing part is defined by the front device carrier section 36. The suction device 14 is arranged in this.

The suction device 14 includes a fan 182. The fan 182 includes a fan wheel 184, which is arranged to be rotatable about an axis of rotation 186. When the cleaning device 10 is operating as intended, the axis of rotation 186 runs parallel or essentially parallel to the direction of gravity 28. The axis of rotation 186 is thus aligned transversely, in particular perpendicularly, to the dirty water outlet longitudinal axis 170 and to the air inlet longitudinal axis 180.

The cleaning device 10 includes a housing 188, which defines a housing interior 190. A pressure-side suction device outlet 192 of the suction device 14 opens into the housing interior 190, specifically in the area of the front housing support section 36, as shown schematically in 14 is shown.

The cleaning device 10 further comprises a switching device 194 for activating and deactivating the suction device 14. The switching device 194 is designed in the form of a rotary switch 196. Alternatively, the switching device can also be designed in the form of a toggle switch.

The switching device 194 is arranged on the top 64 of the cleaning device 10 Hungically designed, namely on the front equipment carrier section 36.

The switching device 194 is further designed to activate and deactivate the fluid delivery device 44, namely to activate and deactivate the conveying device 50.

In the exemplary embodiment shown in the figures, the switching device 194 is also designed to simultaneously activate and deactivate the suction device 14 and the fluid delivery device 44.

In the manner described, all electrical components that are required for the operation of the cleaning device 10, namely the suction device 14 as well as the conveyor device 50 and the switching device 190, are arranged or formed on the front device support section 36. They are connected to the power supply connection 20 via electrical connecting lines (not shown in the figures) in such a way that both the suction device 14 and the conveying device 50 can be activated or deactivated together by actuating the switching device 194.

The conveying device 50 and the suction device 14 are also dimensioned such that a power consumption of the suction device 14 corresponds to at least approximately five times a power consumption of the conveying device 50, in particular at least approximately ten times. In the exemplary embodiment shown in the figures, the power consumption of the suction device 14 is approximately 100 watts, and the power consumption of the conveying device 50 is approximately 10 watts.

In order to be able to transport the cleaning device 10, it includes a carrying handle 198. The carrying handle 198 is designed in the form of a U-shaped bracket 200, with two mutually parallel legs 202 and 204, which are on the one hand on the front device carrier section 36 and on the other hand on the rear device carrier section 38 are arranged. The legs 202 and 204 are connected to one another via a straight handle section 206.

The carrying handle 198 can be pivoted about a handle pivot axis 208 which runs transversely, namely perpendicularly, to the direction of gravity 28 during normal operation of the cleaning device 10. In 2 the carrying handle 198 is shown such that the handle section 206 completely releases the container receptacle 30 in an operating position of the cleaning device 10 and rests laterally on the central device carrier section 40.

The handle pivot axis 208 runs in a central plane 210, in which the longitudinal axis 26 of the device also runs. Due to the configuration described, the carrying handle 198 can be pivoted from the operating position into a carrying position in such a way that the handle section 206 is also positioned in the central plane 210 and then engages over the container receptacle 30.

The center of gravity 212 of the cleaning device 10 lies in the carrying position below the handle section 206, therefore in the central plane 210 or essentially in the central plane 210.

To separate the liquid dirty liquor component 152 into the collecting container 16, namely the dirty water container 18, and in particular to separate it from a dirty fluid stream 216 comprising the liquid dirty liquor component 152 and a gaseous dirty liquor component 434, the cleaning device 10 comprises a separator device 214.

In the exemplary embodiment shown in the figures, the separating device 214 is arranged or formed in the collecting container 16.

The separating device 214 is arranged or formed in the collecting container 16 between the dirty water container inlet 156 and the air outlet 172.

The collecting container 16 includes a removable collecting container lid 218, in the form of the dirty water container lid 164.

The separating device 214 comprises a separating insert 220, which is inserted into the dirty water container 18 and is closed by the dirty water container lid 164 on an upper side thereof.

The separation device 214 comprises a first separation stage 222 and a second separation stage 224. The first separation stage 222 is connected downstream of the dirty water tank inlet 156. The second separation stage 224 is connected downstream of the first separation stage 222.

The first separation stage 222 comprises a deflection element 226 for deflecting the dirty fluid stream 216 flowing into the dirty water container 18. The deflection element 226 is designed in the form of a short pipe section angled at 90 °, which when the cleaning device 10 is operated as intended defines an outlet 228 which flows in a direction opposite or substantially opposite to the direction of gravity 28. The dirty fluid stream 216 can thus be directed against the direction of gravity 28 when it enters the dirty water container 18.

A drip opening 230 is formed on the deflection element 226 in the direction of gravity 28 at the bottom for draining the liquid dirty liquor component 152 into the collecting space 154 of the dirty water container 18.

The first separation stage 222 comprises a deflection bell 232, which is connected downstream of the deflection element 226 and is open in the direction of gravity, for redirecting the dirty fluid flow 216 in the direction of gravity 28 into the collecting space 154 of the dirty water container 18. The deflection bell 232 defines a cross section that is more than twice as large as the outlet of the deflection element 226, so that a flow cross section expands after the deflection element 226, as shown schematically in 7 can be recognized.

The deflection bell 232 is arranged or formed on the dirty water container lid 164. If the dirty water container lid 164 is removed from the dirty water container 18, the deflection bell 232 is also removed at the same time.

The first separation stage 222 thus directs the dirty fluid flow 216 in the manner described, first by 90 ° in a direction counter to the direction of gravity 28 and then immediately by a further approximately 180 ° in a direction parallel to the direction of gravity 28.

The separation insert 220 separates the collecting space 154 from a flow space 234 by a separation insert base 236. The separation insert base 236 is positioned approximately at the level of the dirty water insert longitudinal axis 170. A cover wall 238 of the dirty water container lid 164 lies opposite the separator insert base 236 and closes the flow space 234.

The second separation stage includes the flow space 234 arranged above the collecting space 154 of the dirty water container 18. It serves to pass through the gaseous dirty liquor component 434 and includes a flow space inlet 240 and a flow space outlet 242.

The flow space inlet 240 is formed in the separator insert base 236 and has a substantially rectangular shape. The flow space outlet 242 is also formed in the separator insert base 236 and has a substantially square shape. The flow space inlet 240 fluidly connects the collecting space 154 and the flow space 234. The flow space outlet 242 is fluidly connected to the suction device 14.

The flow space inlet 240 is closed with a separating element 244, which is designed to be gas-permeable and liquid-impermeable. The separating element 244 is formed by a fleece 246. Like in particular 12 clearly visible, the separating element 244 is curved convexly into the flow space 234 against the direction of gravity 28.

In the exemplary embodiment described, a cross section of the flow space inlet 240 is larger than a cross section of the deflection bell 232, so that here the gaseous dirt liquor component 434 flows more slowly through the flow space inlet 240 than in the area of the deflection bell 232.

The flow space outlet 242 is open in the direction of gravity 28 and opens into an upper end 248 of a float shaft 250 extending in the direction of gravity 28.

A lower end 252 of the float shaft 250 is fluidly connected to the collecting space 154. At the lower end 252 in the direction of gravity 28, a fluid-permeable filter element 254 is arranged or formed on the float shaft 250. The filter element 254 has the shape of a sieve 256. Thus, the liquid dirt liquor component 152 can flow through the filter element 254 into the float shaft 250, so that a level of the liquid dirt liquor component 152 in the collecting space 154 and in the float shaft 250 is essentially identical.

A floating element 258 is arranged in the float shaft 250, which is designed such that it floats on the liquid dirty water fleet component 152. Depending on a fill level of the liquid dirt liquor component 152 in the float shaft 250, the floating element 258 then moves up or down in the float shaft 250 counter to or parallel to the direction of gravity 28.

An inner contour of the float shaft 250 is essentially square. An outer contour of the floating element 258 is essentially circular. Nevertheless, the inner contour of the float shaft 250 and the outer contour of the floating element 258 are adapted to one another and essentially correspond to each other, as shown schematically in 13 is shown.

The floating element 258 is in the form of a sleeve 260 that is closed on one side. An open end 262 of the sleeve 260 points in the direction of gravity 28.

A float shaft outlet 264 is arranged at the upper end 248 of the float shaft 250. It essentially comprises a piece of pipe angled at 90°, which is fluidly connected to the air outlet 172. The float shaft outlet 264 is open in the direction of gravity 28. A cross section of the same is smaller than a cross section of the float shaft 250. The gaseous dirty liquor component 434 can flow from the flow space 234 through the upper end 248 into the float shaft 252 and, after a deflection by a further approximately 180 °, exit through the float shaft outlet 264.

The cleaning device 10 further comprises a flow interruption device 266 for interrupting a suction flow generated by the suction device 14 in an interruption position. The flow interruption device 266 includes one between

Valve arrangement 268 arranged in the dirty water tank inlet 156 and the air outlet 172. The valve arrangement 268 includes the floating element 258 and the float shaft outlet 264. In the interrupted position, the floating element 258 closes the float shaft outlet 264, namely when a fill level of the liquid dirty liquor component 152 in the collecting space 154 and in the with this fluidly connected float shaft 250 reaches such a level that a closed end of the sleeve 260 strikes the float shaft outlet 264 and closes it. The float shaft outlet 264 therefore forms a stop 270 for the floating element 258 when moving against the direction of gravity 28, the floating element 258 then closing the float shaft outlet 264 in an air outlet position.

The float shaft 250 includes an upper shaft section 272 and a lower shaft section 274. The upper shaft section 272 is arranged or formed on the separator insert base 236. The lower shaft section 274 adjoins the upper shaft section 272 in the direction of gravity 28 and extends it to a bottom of the dirty water container.

The upper shaft section 272 and the lower shaft section 274 are designed to be detachably connectable to one another. In the exemplary embodiment shown in the figures, a latching connection device 276 is shown schematically for this purpose. By connecting the two shaft sections 272 and 274, the float shaft 250 can be removed from the dirty water container 18 together with the separator insert 220 as an assembly.

Furthermore, the collecting container 16 includes a collecting container securing device 278 for securing the collecting container lid 218 on the collecting container 16 in a closed position. Two locking tabs 280 arranged on sides of the collecting container lid 218 that point diametrically away from one another cooperate with corresponding locking elements formed or arranged on the collecting container 16, so that they engage with one another in the closed position. The locking position is shown schematically in the 1 until 4 shown.

The power supply connection 20 of the cleaning device 10 includes an interface 282 for detachable connection to a battery 284. The interface 282 includes a battery receptacle 286 for non-positively and/or positive connection to a battery housing 288 of the battery 284.

The interface 282 is further designed to electrically conductively connect electrical components of the cleaning device 10 to battery poles of the battery 284. In particular, the interface 282 is electrically conductively connected to switching contacts of the switching device 194, so that an electrical connection is established by appropriate actuation of the switching device 194 in such a way that the battery 284 can supply the suction device 14 and the conveyor 50 with power to operate them.

Alternatively or optionally in addition, in an alternative exemplary embodiment it is provided that the energy supply connection 20 comprises a connection device for connecting the cleaning device 10 to a power network. In this way, the cleaning device can not only be supplied independent of the mains with the battery 284, but also independent of the mains via a connection cable with energy provided by the power network.

The battery 284 can be detachably connected to the cleaning device 10. It is also in the form of a rechargeable battery 284. This proposed embodiment makes it possible to remove the battery 284 from the cleaning device 10 and recharge it when it is empty. In order to continue cleaning immediately, you can then empty battery 284 can be replaced with another charged battery 284.

That in connection with the 1 until 18 The cleaning device 10 described is, as mentioned, designed in the form of a spray extraction device 42. So that a user can quickly and easily clean an object to be cleaned, the cleaning device 10 includes a suction nozzle 290, which is connected to the first suction hose end 66 or, alternatively, can be detachably connected.

The suction nozzle 290 and the first suction hose end 66 can be rotated in a connection area 292 about a connection area longitudinal axis 294 defined by the connection area 292.

The suction nozzle 290 includes a handpiece 296, which is designed to be non-separable from the suction hose 258. Furthermore, the suction nozzle 290 includes a nozzle attachment 298.

In 20 Three nozzle attachments 298 are shown schematically, namely a nozzle attachment 298 in the form of a surface nozzle 300, a nozzle attachment 298 in the form of a crevice nozzle 302 and another nozzle attachment 298 in the form of another crevice nozzle 304.

The handpiece 296 is freely rotatably coupled to the first suction hose end 66, which includes a coupling piece 306. For this purpose, a groove 308 which extends in the circumferential direction and points away from the connecting region longitudinal axis 294 is formed on the coupling piece 306 in the form of an annular groove, into which - as shown schematically in the 34 and 35 shown - two guide members pointing in the direction of the connecting area longitudinal axis 294 engage in the form of projections 309, which are formed on an upper handle part 310 of the handpiece 296.

The upper handle part 310 is essentially sleeve-shaped and has a recess 312 on a side area, which is closed with a closure part 314.

In the area of the recess 312, an opening 316 is formed, through which the first spray hose end 82 is guided. The first spray hose end 82 thus projects into the handpiece 296. Furthermore, the first spray hose end protrudes over the first suction hose end 66.

The first spray hose end 82 is held non-rotatably on the handpiece 296. This means that the first spray hose end 82 also rotates about the connecting region longitudinal axis 294 when the handpiece 296 rotates. However, this means that the entire spray hose 80 inside the suction hose 58 is rotated relative to it. In order to prevent the spray hose 80 and the suction hose 58 from twisting relative to one another, the second spray hose end 84 is held rotatably on the fluid connection 78 as described above.

A handpiece suction channel 318 is formed on the upper handle part 310. The handpiece suction channel 318 defines a first handpiece suction channel end 320 and a second handpiece suction channel end 322. The second handpiece suction channel end 322 is connected to the coupling piece 306, as exemplified in FIGS 20 and 26 is shown.

On the upper handle part 310, in the area of the front end of the handpiece 296, a further opening 324 is arranged, through which a first handpiece spray channel end 326 protrudes and protrudes. The first spray hose end 82 is connected in a fluid-tight manner to a second handpiece spray channel end 328. The second handpiece spray channel end 328 is designed in the form of a sleeve-shaped connecting piece.

A handpiece spray channel 330 extends between the first and second handpiece spray channel ends 326 and 328. Furthermore, a valve device 332 is arranged or designed between the first and second handpiece spray channel ends 326 and 328 for opening and closing the handpiece spray channel 330.

The valve device 332 comprises an actuating element 334 for actuating the valve device 332. The actuating element 334 is in the form of a pivot lever 338 which is mounted on the handpiece 296, namely on the closure part 314, so that it can pivot about a pivot axis 336.

The valve device 332 includes a valve plunger 340, which opens or closes a valve opening 342 formed in the handpiece spray channel 330, depending on the position in which it is located. The valve tappet 340 comprises a deflection surface 344 which is inclined relative to the connecting region longitudinal axis 294, against which a transmission member 348 mounted in a bearing sleeve 346 of the valve device 332 can be displaced in a direction of movement inclined relative to the connecting region longitudinal axis 294. The transmission member is sealed from the bearing sleeve 346.

If the pivot lever 338 is pivoted towards the valve device 332, the transmission member 348 is pressed towards the deflection surface 344, so that a front end 350 of the transmission member 348 slides on the deflection surface 344 and moves the valve tappet 340 in the direction of the second handpiece spray channel end 328. A biasing element 352 of the valve device 332 is arranged between the valve plunger 340 and the second handpiece spray channel end 328. The biasing element 352 is in the form of a compression spring 354. It serves to hold the valve device 332 in a basic position in which the handpiece spray channel 330 is closed. This basic position is schematic in the 24 and 25 shown. 26 shows schematically an open position of the valve device 332.

The biasing element 352 holds the valve tappet 340, which forms a valve member 356 of the valve device 332, in a closed position under bias. As described, the actuating element 334 is designed to cooperate with the valve member 356 to move the valve member 356 against the action of the biasing element 352 from the closed position into the open position deflected from the closed position.

The closure part 314 closes the recess 312, which together define a valve receiving space 358 for the valve device 332. The handpiece spray channel 330 thus runs essentially parallel to the handpiece suction channel 318 through the handpiece 296, namely through the valve receiving space 358.

The handpiece 296 and the nozzle attachments 298 are designed to be detachably connectable to one another. This makes it possible, depending on the cleaning task to be processed, to connect the handpiece 296 with the most suitable nozzle attachment 298. For this purpose, the suction nozzle 290 includes a suction nozzle connecting device 360 for non-positively and/or positively connecting the handpiece 296 and one of the nozzle attachments 298 in a suction nozzle connecting position. Such a suction nozzle connection position is particularly in the 22 until 28 shown schematically.

In the exemplary embodiment of the suction nozzle 290 shown in the figures, the suction nozzle connection device 360 is designed in the form of a latching or snap connection device 362. The suction nozzle connecting device 360 includes first and second suction nozzle connecting elements 364 and 366, which are arranged or formed on the handpiece 296 on the one hand and on the nozzle attachments 298 on the other hand. The two suction nozzle connecting elements 264 and 266 are in a force-fitting and/or positive engagement in the suction nozzle connecting position and in a suction nozzle separating position, as shown schematically in 20 shown, they are completely separated from each other.

The suction nozzle connecting device 360 includes a connector 368 on the respective nozzle attachment 298, which can be inserted into the first handpiece suction channel end 320 in a defined rotational position. A second connecting member is arranged or formed on the connector 368, specifically in the form of a locking projection 372 formed on a free end of a leaf spring element 370. The free end points in the direction of the handpiece 296. At the first handpiece suction channel end 320 there is a locking recess on a flexible unlocking member 376 374 formed, in which the locking projection 372 is received in the suction nozzle connection position. This is schematic in the 24 and 26 clearly visible.

The unlocking member 376 is formed on the handpiece 296 essentially opposite the actuating element 334. A user can hold the handpiece 296 with one hand and, for example, operate the actuating element 334 with the middle or index finger. To release the nozzle attachment 298 from the handpiece 296, the user can press the unlocking member 376 with his thumb, whereby the leaf spring element 370 is pivoted into the handpiece suction channel 318 and so the locking projection 372 emerges from the locking recess 374, so that the nozzle attachment 298 is pulled off the handpiece 296 can be.

The nozzle attachments 298 each include a nozzle attachment suction channel 378 and a nozzle attachment spray channel 380. The nozzle attachment spray channel 380 includes a first nozzle attachment spray channel end 382 and a second nozzle attachment spray channel end 384. The nozzle attachment suction channel 378 includes a first nozzle attachment suction channel end 386 and a second nozzle attachment suction channel end 388.

The nozzle attachments 298 are designed such that they and the handpiece 296 are sealed relative to one another in the suction nozzle connection position. This is achieved in particular in that the second nozzle attachment suction channel end 388 and the first handpiece suction channel end 320 are sealed relative to one another in the suction nozzle connection position. Furthermore, the second nozzle attachment spray channel end 384 and the first handpiece spray channel end 326 are also sealed relative to one another.

A spray nozzle 390 is also arranged or formed on the nozzle attachment spray channel 380. There is also a nozzle attachment on the first Spray channel end 382 has a nozzle attachment spray channel outlet 392 arranged or formed. In the case of the crevice nozzle 302, the spray nozzle 390 is arranged or formed between the first nozzle attachment spray channel end 382 and the second nozzle attachment spray channel end 384. In the case of the surface nozzle 300 and the crevice nozzle 304, the spray nozzle 390 forms the nozzle attachment spray channel outlet 392.

In the case of the surface nozzle 300 and the crevice nozzle 304, the spray nozzle 390 is designed as a separate component and is attached in a sealed manner to the first nozzle attachment spray channel end 382.

In the case of the surface nozzle 300, the first nozzle attachment suction channel end 386 projects beyond the first nozzle attachment spray channel end 382. The first nozzle attachment suction channel end 386 is designed in the surface nozzle 300 in the form of an elongated opening which runs transversely to the connecting region longitudinal axis 294. In addition, the nozzle attachment suction channel 378 is angled. The spray nozzle 390 is free-standing in the surface nozzle 300 and is only covered on one side by the nozzle attachment suction channel 378.

In the case of the crevice nozzle 304, the nozzle attachment spray channel 380 extends within the nozzle attachment suction channel 378.

In the case of the crevice nozzle 302, the spray nozzle 390 is formed in one piece, namely monolithically. There is therefore no need to install the spray nozzle 390, as is required with the surface nozzle 300 and the crevice nozzle 304.

In the case of the crevice nozzle 302, the spray nozzle 390 is designed in the form of a cross-sectional narrowing 394 on the nozzle attachment spray channel 380. Here, the spray nozzle 390 is spaced from the first nozzle attachment spray channel end 382 and is thus arranged between the first nozzle attachment spray channel end 382 and the second nozzle attachment spray channel end 384.

In the case of the crevice nozzle 302, a nozzle attachment suction channel cross section of the nozzle attachment suction channel 378 increases continuously starting from the first nozzle attachment suction channel end 386 to the second nozzle attachment suction channel end 388. Furthermore, in the case of the crevice nozzle 302, a nozzle attachment spray channel cross section of the nozzle attachment spray channel 380 continuously decreases starting from the first nozzle attachment spray channel end 382 to the spray nozzle 390 and continuously increases from the spray nozzle 390 to the second nozzle attachment spray channel end 384. This structural design of the crevice nozzle 302 makes it possible to design it in one piece, namely monolithically. The crevice nozzle 302 can thus be produced as an injection molded part in a single injection process.

Furthermore, the second nozzle attachment spray channel end 384 and the first handpiece spray channel end 326 are sealed relative to one another in the suction nozzle connection position.

Two holding members 396 are arranged to protrude laterally on the nozzle attachments 298. They serve to detachably connect the nozzle attachments 298 to the housing 188, specifically in the area of the rear device carrier section 38.

To couple the elastically deformable holding members 296, holding member receptacles 398 are formed on the side of the rear device carrier section 38, which can be brought into engagement with the holding members 396 in a force-fitting and/or positive manner. A cross-sectional narrowing 400 is formed on the holding member receptacles 398, on which lateral projections 402 of the two holding members 396, which point away from one another in opposite directions, slide on and the holding members 396 arranged in pairs can pivot slightly towards one another. The holding members 396 spring back into their basic position when the projections 402 engage behind the cross-sectional narrowing 400. 17 shows the holding members 316 before engaging with the holding member receptacle 398. 18 shows schematically the holding members 396 which are in engagement with the holding member receptacle 398.

As schematically in 16 shown, one of the two holding member receptacles 398 serves to store one of the two nozzle attachments 298, which is connected to the handpiece 296. The further nozzle attachment 298 in the form of the crevice nozzle 302 can then be securely held and stored on the other side of the rear device carrier section 38 until it is needed and replaced with the surface nozzle 300 on the handpiece 296.

As described above, the cleaning device 10 forms part of a modular cleaning system 404, designated overall by the reference number 204. As in 42 Shown schematically, a spray extraction module 428 comprising the cleaning fluid container 48 and the dirty water container 18 can optionally be inserted into the container receptacle 30 of the cleaning device 10 which forms a module receptacle 440, that is to say into the container receptacle 30 which is formed on the device carrier 12. In this way, the cleaning device 10 can be used as a spray extraction device 42.

Alternatively, a suction module 436 can be inserted into the container receptacle 30, which only has a single collecting container 16 in the form of a Suction container 406 includes, which alone completely or substantially completely fills the container receptacle 30. Such a combination enables the design of a cleaning device 10 in the form of a suction device 408, for example in the form of a wet/dry vacuum cleaner.

A further embodiment of the modular cleaning device 10 provides for a steam cleaning device 410 to be formed, namely by inserting a steam generating module 412 with a steam generating device 414 and a fluid container 416 into the container receptacle 30. For example, water can be filled into the fluid container 416, which is evaporated with the steam generating device 414, so that hot steam can be released with the cleaning device 10, now as a steam cleaning device 410. The fluid delivery device described in detail above is used to deliver the steam.

An exemplary embodiment of a cleaning device 10 in the form of a suction device 408 is exemplified in the 36 until 41 shown schematically. In the suction device 408, instead of the cleaning fluid container 48 and the dirty water container 18, a single suction container 406 is inserted into the container receptacle 30.

The collecting container 16 is therefore designed in the suction device 408 in the form of the suction container 406 and is arranged in the container receptacle 30 in a suction working position of the cleaning device 10 - this therefore forms a suction device 408 as described.

A recess 418 is formed on the underside of the suction container 406, into which the connecting piece 118 of the cleaning device 10 engages. Since there is no cleaning fluid container 48 and therefore no cleaning fluid 46, the connecting piece 118 remains without function.

A suction container inlet 420 and a suction container air outlet 422 are formed on the suction container 406. These are arranged and positioned in such a way that the suction container air outlet 422 is connected to the air inlet 174 on the container receptacle 30 in a fluid-effective and fluid-tight manner. Furthermore, the suction container inlet 420 is connected to the dirty water outlet 158 on the container receptacle 30 in a fluid-effective and fluid-tight manner in a suction position. In this way, the sucked up dirt liquor 150 passes through the suction container inlet 420 into a collecting space 154 defined by the suction container 406.

The suction container 406 is closed with the collecting container lid 218. The collecting container securing device 278 with the two locking tabs 280 serves to securely secure the collecting container lid 218 to the collecting container 16, i.e. to the suction container 406.

A separation device 214 is also arranged or formed on the suction container 406, which comprises a first separation stage and a second separation stage 224.

The first separation stage 222 on the suction container 406 also includes a deflection element 226 in the form of a baffle plate 424 pointing in the direction of the suction container inlet 420 and arranged at a distance from it.

The second separation stage 224 includes a separation element 426 that closes the suction container air outlet 422.

The separating element 426 includes a filter 428. It is sleeve-shaped and includes a sleeve wall 430, which has a plurality of large-area openings 432 extending over a circumference of the sleeve wall 430. The filter 428 closes these openings 432. It is designed to retain liquids but allow air to pass through.

The separating element 426 is arranged directly in front of the suction container air outlet 422 and is designed concentrically to the air inlet longitudinal axis 180. The separating element 426 thus projects into the suction container 406, in a direction transverse, namely perpendicular, to the direction of gravity 28.

The suction container 406 as well as the dirty water container 18 and the cleaning fluid container 48 are dimensioned such that the suction container 406 defines a suction container volume, that the dirty water container 18 defines a dirty water container volume and that the cleaning fluid container 48 defines a cleaning fluid container volume, the suction container volume being approximately the sum of the dirty water container volume and the Cleaning fluid container volume corresponds. In other words, a suction container volume is available for the suction container 406, which the dirty water container 18 and the cleaning fluid container 48 define together.

So that in the cleaning device 10, when it is used as a spray extraction device 42, the entire cleaning fluid 46 can be safely accommodated in the dirty water container 18, the cleaning fluid container volume corresponds to a maximum of approximately 50% of the dirty water container volume.

Another special property of the cleaning device 10, in particular the cleaning f fluid container 48 in conjunction with the crevice nozzle 302, is that the filling opening 104 is dimensioned such that the crevice nozzle 302 can be inserted into the cleaning fluid container 48 through the filling opening 104. Cleaning fluid 46 can thus be sucked directly through the nozzle attachment suction channel 378 in order to clean not only the handpiece suction channel 318, but also the suction hose 58. If necessary, cleaning fluid 46 can then also be dispensed into the cleaning fluid container 48 through the spray nozzle 390 when the actuating element 334 of the valve device 332 on the handpiece 296 is actuated.

As already mentioned, the center of gravity 212 of the cleaning device 10 lies in the area of the container receptacle 30, i.e. in particular in the middle device support section 40. When using the cleaning device 10 as a spray extraction device 42, the position of the center of gravity 212 is essentially independent of the intended filling of the collecting container 16 and/or of the cleaning fluid container 48. If the cleaning fluid 46 is completely discharged and received in the collecting container 16, the center of gravity 212 moves slightly in the container receptacle 30 towards the front equipment carrier section 36. Nevertheless, a position of the center of gravity 212 remains in the carrying position below the handle section 206 for optimal handling of the cleaning device 10, so that a user can lift and carry the cleaning device 10 in a very balanced manner.

The course of the flow of the cleaning fluid 46 from the cleaning fluid container 48 to the spray nozzle 390 is in 4 shown with the solid lines. The cleaning fluid is conveyed from the cleaning fluid container 48 through the connecting line 132 to the conveyor device 50, namely by the conveyor device 50 sucking the cleaning fluid 46 out of the cleaning fluid container 48. From the conveying device 50, the cleaning fluid 46 is conveyed through the connecting line 94 to the fluid connection 78 and then from there through the spray hose 80 to the handpiece 296, so that it can be dispensed through the spray nozzle 390 of the nozzle attachment 298 when the valve device 332 is actuated.

Conversely, the dirty fluid stream 216, in. is drawn from a surface to be cleaned 4 shown in dashed lines, guided through the nozzle attachment suction channel 378 and the handpiece suction channel 318 into the suction hose 58. From the suction hose 58, the dirty fluid stream 216 passes through the suction connection 56 into the dirty water tank 18. The liquid dirty liquor component 152 is separated in the dirty water tank 18 as described, so that the gaseous dirty liquor component 434 passes through the two separation stages 222 and 224 of the separating device 214 in the dirty water tank 18 and into the Air inlet 174 can flow to the container receptacle 30. From there, the gaseous dirt liquor component 434 is passed through the piping arranged in the front equipment support section 36 to the suction device 14.

By sealing the interconnected components, a good suction and thus cleaning result can be achieved even with a low power consumption of the suction device 14.
