Technical Field

[0001] The present invention relates to a suction hose for a cleaning device, in particular for a spray extraction device, wherein the suction hose comprises a first suction hose end and a second suction hose end, wherein the second suction hose end is fluidically connectable to a suction interface of the cleaning device, wherein the suction hose comprises a spray hose having a first spray hose end and a second spray hose end, wherein the second spray hose end is fluidically connectable to a fluid interface of the cleaning device.

[0002] The invention further relates to a suction nozzle attachment for a cleaning device, in particular for a suction nozzle of a spray-extraction device, the suction nozzle comprising a handpiece and a suction nozzle attachment.

[0003] The invention relates to a cleaning device, in particular a cleaning device in the form of a portable cleaning device, comprising a suction device, a suction connection fluidically connected to the suction device and a suction hose connected or connectable to the suction connection. Background Art

[0004] Such cleaning devices are known in different embodiments. For example, these cleaning devices are used in the form of spray-extraction devices, which in particular also have a suction hose and a suction nozzle attachment of the type described at the beginning.

[0005] The problem with such cleaning devices is especially their operability. In particular, the suction hose of the type described at the beginning can be entangled with the spray hose, making it difficult for the user to operate it. Summary of the invention

[0006] It is therefore an object of the present invention to improve a suction hose, a suction nozzle attachment and a cleaning device of the type mentioned at the outset in such a way that they can be handled more easily.

[0007] According to the invention, this object is achieved in a suction hose of the type mentioned in the introduction in that the first suction hose end is connected or connectable to the suction nozzle, the suction nozzle and the first suction hose end being designed so as to be twistable relative to one another.

[0008] Such a design enables improved handling, in particular when used in conjunction with a spray extraction device. The proposed improvement makes it possible for the user to rotate the suction nozzle without having to rotate the entire suction hose, but it is sufficient for the user to rotate the suction nozzle only relative to the suction hose, in particular relative to the first suction hose end. In particular, if the suction hose comprises a spray hose for the cleaning fluid to be dispensed, unintentional twisting of the suction hose and / or the spray hose and thus pinching can be avoided.

[0009] Advantageously, the suction nozzle and the first suction hose end can be twisted in the connection region about a connection region longitudinal axis defined by the connection region, thereby improving the handling of the suction hose.

[0010] If the shower hose is surrounded by the suction hose, the handling of the suction hose and the cleaning device can be improved in particular. For example, the shower hose can be arranged or positioned in the interior of the suction hose and extend over the entire length of the suction hose or even extend beyond it. However, it can also be advantageous to arrange or form the shower hose outside the suction hose. For example, it can be connected to the suction hose in a detachable manner so that it can be removed or replaced when it is not required or is damaged.

[0011] If the shower hose is constructed separately from the suction hose and the shower hose and the suction hose are arranged or designed to be twistable relative to each other, the suction hose and the cleaning device can be constructed simply and inexpensively. This makes it possible in particular to replace a damaged suction hose without having to replace a shower hose that is still functioning properly. Conversely, this is also possible in the event of a damaged shower hose. In particular, by providing the shower hose and the suction hose with twistability, it is possible to prevent the shower hose and the suction hose from twisting in an undesirable manner. This can prevent the suction hose and / or the shower hose from being pinched.

[0012] Advantageously, the suction nozzle comprises a handpiece and at least one suction nozzle attachment, and the handpiece and the suction hose are twistable relative to each other. Such a design makes it possible, in particular, for the user to move and rotate the handpiece as required for completing the cleaning task. However, the suction hose does not have to rotate together and can remain in its positioning or rotational position. This requires the user to invest less force when cleaning. The handling of the suction hose is thus improved. In particular, the handpiece can be connected to the suction nozzle attachment in a non-detachable manner, or can be formed in one piece, in particular in a monolithic manner, with the suction nozzle attachment.

[0013] Advantageously, the handpiece and at least one suction nozzle attachment are configured to be detachably connected to each other. Such a design can in particular enable the handpiece to remain permanently connected to the first suction hose end and only couple different suction nozzle attachments to the handpiece for different cleaning tasks.

[0014] The handpiece and the at least one suction nozzle attachment can be coupled to one another in a simple manner if the suction nozzle comprises a suction nozzle connecting device for connecting the handpiece and the at least one suction nozzle attachment in a force-fitting and / or form-fitting manner in the suction nozzle connecting position.

[0015] If the suction nozzle connection is designed in the form of a latching or snap-on connection, the suction nozzle can be designed simply and inexpensively.

[0016] For operating the suction nozzle, it is advantageous if the suction nozzle connection device comprises a first and a second suction nozzle connection element, which are arranged or configured on the handpiece on the one hand and on the other hand on the at least one suction nozzle attachment, and the first and second suction nozzle connection elements are in engagement in a force-locked and / or form-locked manner in the suction nozzle connection position, and are completely separated from each other in the suction nozzle separation position. For example, the first and second suction nozzle connection elements can be configured in the form of cooperating latching or snap-on connection elements, for example in the form of a latching recess formed on the handpiece and a latching nose on the at least one suction nozzle attachment that can move relative to the latching recess.

[0017] Advantageously, at least one suction nozzle attachment comprises a suction nozzle attachment suction channel and a spray nozzle attachment channel. Such a suction nozzle attachment can be advantageously used in combination with a spray extraction device. Therefore, the suction nozzle can not only receive dirt through the suction nozzle attachment suction channel, but also output cleaning fluid through the spray nozzle attachment channel.

[0018] In particular, a particularly compact design of the at least one suction nozzle attachment can be achieved if the suction nozzle attachment spray channel is arranged or formed within the suction nozzle attachment suction channel or is surrounded by the suction nozzle attachment suction channel.

[0019] In order to be able to discharge the 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 at the first nozzle attachment spray channel.

[0020] In order to be able to apply the cleaning fluid as finely and over a large area as possible, it is advantageous to arrange or construct a spray nozzle at the nozzle attachment spray channel. The spray nozzle can be arranged on one of the two ends of the nozzle attachment spray channel or can also be arranged between the two ends.

[0021] Advantageously, the spray nozzle is arranged or constructed between the first nozzle attachment spray channel end and the second nozzle attachment spray channel end. Therefore, the spray of the cleaning fluid coming out of the nozzle can be particularly limited by the section of the nozzle attachment spray channel. For example, unrestricted application of the cleaning fluid can be prevented thereby.

[0022] If the spray nozzle forms the outlet of the nozzle attachment spray channel, the suction nozzle can be designed to be simple and compact.

[0023] If the spray nozzle is integrally, in particular monolithically, formed onto the suction nozzle attachment, the at least one suction nozzle attachment can be designed particularly inexpensively and compactly. It is therefore possible in particular to design the suction nozzle attachment as a plastic injection-molded part, even in one process step. This eliminates the need to mount the spray nozzle on the suction nozzle attachment.

[0024] The spray nozzle can be configured in a simple manner as a cross-sectional narrowing on the nozzle attachment spray channel. In particular, the spray nozzle can be configured as a cross-sectional narrowing at the first nozzle attachment spray channel end.

[0025] Advantageously, the nozzle attachment suction channel comprises a first nozzle attachment suction channel end and a second nozzle attachment suction channel end, and the nozzle attachment suction channel cross section of the nozzle attachment suction channel increases continuously from the first nozzle attachment suction channel end toward the second nozzle attachment suction channel end. This design makes it possible, in particular, to configure 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 therefore be higher than the speed of the suction flow at the second nozzle attachment suction channel end, so that dirt can be particularly easily sucked away with the nozzle attachment.

[0026] Preferably, the nozzle attachment spray channel cross section of the nozzle attachment spray channel decreases continuously from the first nozzle attachment spray channel end to the spray nozzle and increases continuously from the spray nozzle toward the second nozzle attachment spray channel end. This design of the nozzle attachment spray channel can be realized in particular that it can be formed in one working step by injection molding.

[0027] Advantageously, at least one suction nozzle attachment is configured as one of the forms of the suction nozzle attachment also described below. Thus, the suction hose as a whole also has the advantages described in conjunction with the preferred embodiment of the suction nozzle attachment.

[0028] In order to simplify the 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 so as to protrude beyond the first suction hose end.

[0029] In order to be able to achieve a stable, fluid-tight connection between the spray hose and the handpiece, it is advantageous if the first spray hose end is held on the handpiece in a non-twistable manner.

[0030] It is also advantageous if the handpiece comprises a handpiece spray channel, which comprises a first handpiece spray channel end and a second handpiece spray channel end, and a valve device is arranged or configured between the first handpiece spray channel end and the second handpiece spray channel end for opening and closing the handpiece spray channel. This design allows the user to apply the cleaning fluid with the suction nozzle in a particularly simple manner. To this end, the user only has to actuate the valve device in order to open the handpiece spray channel.

[0031] For operating the cleaning device, it is advantageous if the valve device comprises an actuating element for actuating the valve device. Thus, the user can actuate the valve device, for example, with a finger cooperating with the actuating element. In particular, the actuating element can be arranged on the handpiece in the opposite direction to the suction nozzle connecting element with respect to the longitudinal axis of the handpiece. In this way, it can be prevented that when the actuating element is actuated, the suction nozzle connecting element is accidentally actuated and the suction nozzle attachment is loosened from the handpiece.

[0032] Preferably, the operating element is configured in the form of a swivel lever that is pivotably supported on the handpiece. Such a swivel lever can be realized in a simple manner and can also directly cooperate with the valve mechanism of the valve device.

[0033] Advantageously, the valve device comprises a preload element, which serves to hold the valve device in a basic position in which the spray channel of the handpiece is closed. This design makes it possible, in particular, to discharge cleaning fluid only when the valve device is actuated. The valve device can be designed in a simple manner if the preload element is designed in the form of a compression spring. For example, the preload element can be designed in the form of a helical spring or a leaf spring.

[0034] Advantageously, the prestressing element holds the valve mechanism of the valve device in the closed position under prestressing. Therefore, it is particularly possible to ensure that the nozzle attachment spray channel remains closed in a defined and reliable manner in the closed position.

[0035] Advantageously, the operating mechanism is configured to cooperate with the valve mechanism so that the valve mechanism moves from the closed position to an open position deviating from the closed position against the effect of the preload element. This can be achieved, for example, if the operating element on the handpiece pivots and moves the valve mechanism in the described manner.

[0036] Preferably, the second nozzle attachment spray channel end and the first handpiece spray channel end are close to each other in the suction nozzle connection position. In this way, it can be achieved in particular that the cleaning fluid can only come out from the first nozzle attachment spray channel end, but not from the place where the second nozzle attachment spray channel end and the first handpiece spray channel end are in engagement with each other.

[0037] According to another preferred embodiment, it can be provided that the handpiece includes a handpiece suction channel, the handpiece suction channel includes a first handpiece suction channel end and a second handpiece suction channel end, and the second suction nozzle attachment suction channel end and the first handpiece suction channel end are relatively close to each other in the suction nozzle connection position. This design has the advantage that dirt or dirty water cannot come out from the place where the second suction nozzle attachment suction channel end and the first handpiece suction channel end are in engagement with each other.

[0038] Preferably, at least one suction nozzle attachment and handpiece are close to each other in the suction nozzle connection position. In this way, the cleaning effect of the cleaning device can be improved, because dirty objects or dirty baths can not come out from the transition area between at least one suction nozzle attachment and the handpiece.

[0039] Furthermore, the object mentioned at the outset is achieved according to the invention in a suction nipple attachment of the type mentioned at the outset in that the suction nipple attachment is designed in one piece, in particular in one piece.

[0040] Therefore, the suction nozzle attachment can be constituted in a simple and inexpensive manner. At least one suction nozzle attachment can be configured as a slit suction nozzle, for example. In particular, it can therefore also be constituted in one working step by injection molding.

[0041] Advantageously, at least one suction nozzle attachment comprises a suction nozzle attachment suction channel and a spray nozzle attachment channel. Such a suction nozzle attachment can be advantageously used in combination with a spray extraction device. Therefore, the suction nozzle can not only receive dirt through the suction nozzle attachment suction channel, but also output cleaning fluid through the spray nozzle attachment channel.

[0042] In particular, a particularly compact design of the at least one suction nozzle attachment can be achieved if the suction nozzle attachment spray channel is arranged or formed within the suction nozzle attachment suction channel or is surrounded by the suction nozzle attachment suction channel.

[0043] In order to be able to discharge the 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 at the first nozzle attachment spray channel.

[0044] In order to be able to apply the cleaning fluid as finely and extensively as possible, it is advantageous to arrange or construct a spray nozzle at the nozzle attachment spray channel. This spray nozzle can for example be arranged on one of the two ends of the nozzle attachment spray channel or can also be arranged between the two ends.

[0045] Advantageously, the spray nozzle is arranged or constructed between the first nozzle attachment spray channel end and the second nozzle attachment spray channel end. Therefore, the spray of the cleaning fluid coming out of the nozzle can be particularly limited by the section of the nozzle attachment spray channel. For example, unrestricted application of the cleaning fluid can be prevented thereby.

[0046] If the spray nozzle forms the outlet of the nozzle attachment spray channel, the suction nozzle can be designed to be simple and compact.

[0047] If the spray nozzle is integrally, in particular monolithically, formed onto the suction nozzle attachment, the at least one suction nozzle attachment can be designed particularly inexpensively and compactly. It is therefore possible in particular to design the suction nozzle attachment as a plastic injection-molded part, even in one process step. This eliminates the need to mount the spray nozzle on the suction nozzle attachment.

[0048] The spray nozzle can be configured in a simple manner as a cross-sectional narrowing on the nozzle attachment spray channel. In particular, the spray nozzle can be configured as a cross-sectional narrowing at the first nozzle attachment spray channel end.

[0049] Advantageously, the nozzle attachment suction channel comprises a first nozzle attachment suction channel end and a second nozzle attachment suction channel end, and the nozzle attachment suction channel cross section of the nozzle attachment suction channel increases continuously from the first nozzle attachment suction channel end toward the second nozzle attachment suction channel end. This design makes it possible, in particular, to configure 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 therefore be higher than the speed of the suction flow at the second nozzle attachment suction channel end, so that dirt can be particularly easily sucked away with the nozzle attachment.

[0050] Preferably, the nozzle attachment spray channel cross section of the nozzle attachment spray channel decreases continuously from the first nozzle attachment spray channel end to the spray nozzle and increases continuously from the spray nozzle toward the second nozzle attachment spray channel end. This design of the nozzle attachment spray channel can be realized in particular that it can be formed in one working step by injection molding.

[0051] The object mentioned at the outset is achieved according to the invention in a cleaning appliance of the type mentioned at the outset in that the suction hose is designed in the form of one of the preferred embodiments of the suction hose described above.

[0052] A cleaning device equipped with such a suction hose then also has the advantages described above in conjunction with the preferred embodiment of the suction hose. In particular, such a suction hose can improve the overall operation of the cleaning device.

[0053] Advantageously, the second suction hose end of the suction hose is connected to the suction interface or can be connected in a detachable manner. Depending on the design, the suction hose can therefore remain on the cleaning device permanently, or can be replaced as needed.

[0054] According to another preferred embodiment, it can be provided that the cleaning device includes a fluid output device for outputting the cleaning fluid. Therefore, the cleaning device can be configured, for example, as a spray-extraction device, which can output the cleaning fluid onto the surface to be cleaned. Then, the applied cleaning fluid can be sucked away from the surface to be cleaned by a suction device.

[0055] Advantageously, the fluid output device comprises a spray hose, and the spray hose comprises a first spray hose end and a second spray hose end. Such a spray hose can especially realize that the cleaning fluid is transported to a place away from the cleaning fluid container without moving the cleaning device for this purpose.

[0056] If the fluid dispensing device comprises a conveying device, the cleaning fluid can be dispensed in a simple manner. The conveying device can be used to convey the cleaning fluid from the cleaning fluid container, for example, via a connecting line to a handpiece with a spray nozzle that can be operated by a user.

[0057] Advantageously, the second spray hose end is connected to the conveying device fluidically. Therefore, the cleaning fluid can be conveyed from the conveying device to the second spray hose end, and therefore conveyed to the handpiece of the suction nozzle via the spray hose.

[0058] Advantageously, the cleaning device comprises a fluid connection and the second spray hose end is fluidically connected to the fluid connection, in particular in a fluid-tight manner. This design makes it possible in particular to convey the cleaning fluid into the spray hose via the fluid connection. The tight fit between the fluid connection and the second spray hose end prevents losses of cleaning fluid in the connection area.

[0059] If the fluid interface is surrounded by the suction interface, the cleaning device can be constructed particularly compact. In particular, the suction hose can be connected to the cleaning device, wherein the spray hose is arranged in the interior of the suction hose. Alternatively, it may also be advantageous that the fluid interface is arranged or constructed outside the suction interface, in particular arranged or constructed next to the suction interface. This design can especially realize a simple and possibly separated coupling with a suction hose including an external spray hose.

[0060] In order to be able to convey cleaning fluid into the shower hose, it is advantageous if the fluid connection is fluidically connected to the conveying device, in particular to the pressure side of the conveying device.

[0061] According to a further preferred embodiment, it can be provided that the cleaning device is designed in the form of a spray extraction device.

[0062] Advantageously, the cleaning device comprises a device carrier, an energy supply interface and at least one collecting container, the suction device is arranged or constructed on the device carrier and is fluidically connected to the at least one collecting container, the cleaning device defines a device longitudinal axis that extends transversely, especially vertically, relative to the direction of gravity during operation as specified, the suction device, the at least one collecting container and the at least one energy supply interface are arranged or positioned along the device longitudinal axis or substantially along the device longitudinal axis, so that the at least one collecting container is arranged between the suction device and the at least one energy supply interface on the device carrier. Therefore, the cleaning device can be carried in a simple manner and comfortably. This special arrangement of the suction device, the collecting container and the energy supply interface on the device carrier can be achieved in particular that the center of gravity of the cleaning device is predetermined as far as possible in the center, i.e. in the middle. Ideally, the center of gravity is located in the region of the at least one collecting container, so that the position of the center of gravity does not change or only changes slightly even when the collecting container is filled. Such a design scheme can achieve labor-saving lifting in portable cleaning devices, because these portable cleaning devices are very well balanced due to the proposed arrangement of their components.

[0063] Preferably, the energy supply interface comprises an interface for detachably connecting to a battery. In particular, this allows the cleaning device to be configured in the form of a battery-operated cleaning device, so that the cleaning device can be operated independently of the power grid.

[0064] Advantageously, the interface comprises a battery receptacle for non-positive and / or positive connection to a battery housing of a battery. In particular, the battery receptacle can be arranged or designed such that the battery can be inserted into the battery receptacle in the direction of gravity, i.e., for example, from above. Thus, if the cleaning device is placed on a flat or substantially flat surface, no additional fixing of the battery on the cleaning device is required.

[0065] Advantageously, the interface is designed to electrically connect the electrical components of the cleaning device to the battery terminals of the battery. In particular, the electrical components can be a control device for the suction device or the cleaning device, or also a switch device for activating or deactivating the suction device. If the cleaning device optionally includes a conveying device, such as a pump, the interface can also be directly or indirectly connected to the conveying device in an electrically conductive manner so that the conveying device can be supplied with electrical energy.

[0066] Advantageously, the energy supply interface device comprises a connection device for connecting the cleaning device to the power grid. In particular, the connection device can include a connection cable in order to connect the cleaning device directly to the power grid. However, the connection device can also include a connection socket in order to selectively engage with the connection cable. For example, the cleaning device can thus be operated either with battery power or with network power.

[0067] According to a further preferred embodiment, it can be provided that, in particular also in a cleaning device of the type mentioned at the outset, the device carrier comprises a container receptacle, and the container receptacle is designed to receive at least one collecting container in an operable state of the cleaning device. In particular, this design allows the at least one collecting container to be arranged in a defined manner on the cleaning device in order to operate the cleaning device. In particular, dirt can thus be transported into the at least one collecting container by means of a suction device.

[0068] Advantageously, the cleaning device defines a front side and a rear side, and the suction device is arranged or constructed in a front device carrier section including the front side, and the energy supply interface device is arranged or constructed on a rear device carrier section including the rear side. This design makes it possible in particular to achieve an optimal balance of the cleaning device. Arranging the suction device in the front device carrier section makes it possible in particular to provide a suction interface in this area, which can be connected to a suction hose. In order to balance the weight of the suction device, it is advantageous to arrange the energy supply interface at the rear device carrier section, because, for example, a battery coupled to the energy supply interface can form a counterweight relative to the suction device.

[0069] Preferably, the container receptacle is arranged or constructed on the middle device carrier section, and the middle device carrier section is arranged or constructed between the front device carrier section and the rear device carrier section. Arranging or constructing the container receptacle in the proposed manner makes it possible in particular to predetermine the center of gravity of the cleaning device at the middle device carrier. The position of the center of gravity then does not change, or changes only slightly, when the container receptacle is supplied with cleaning material or dirty bath.

[0070] Advantageously, the fluid output device comprises a cleaning fluid container. The cleaning fluid required for cleaning can be injected into the cleaning fluid container and dispensed with the fluid output device of the cleaning device. In particular, the cleaning fluid can be a mixture of water or water and a cleaning agent.

[0071] If the transport device is arranged or constructed in the front device carrier section, a particularly compact construction of the cleaning device can be achieved. In particular, the transport device can be arranged or constructed together with the suction device in the front device carrier section.

[0072] If the conveying device is designed in the form of a pump, the cleaning fluid can be conveyed in a simple manner.

[0073] If the pump is designed in the form of a diaphragm pump or piston pump, the cleaning device can be realized simply and cheaply. For example, a diaphragm pump can be operated permanently, that is to say even when the output of the cleaning fluid is blocked, in particular by a valve device on a handpiece with a spray nozzle that can be operated by a user.

[0074] Advantageously, the cleaning device, in particular also of the type mentioned at the outset, comprises a suction connection arranged or constructed on the device carrier for connection to a suction hose. Such a suction connection in particular enables the conveying of dirt or dirty water into the cleaning device, in particular into at least one collecting container, by means of the suction hose via the suction connection.

[0075] If the suction connection is arranged or constructed on the front device carrier section, the cleaning device is particularly easy to operate. In particular, the suction connection can be arranged or constructed on the front side of the cleaning device.

[0076] Alternatively, the suction hose can also be permanently connected to the suction connection.

[0077] Advantageously, the cleaning device, in particular also of the type mentioned at the outset, comprises a suction hose, which comprises a first suction hose end and a second suction hose end, and the second suction hose end is fluidically connected or connectable to the suction device. This design makes it possible in particular to receive dirt with the first suction hose end during operation of the cleaning device and to convey it to the suction device via the suction hose.

[0078] The cleaning device can be operated in a simple manner if the second suction hose end is connected or can be detachably connected to the suction connection.

[0079] In order to collect dirt in a simple and defined manner, it is advantageous if the first suction hose end is connected to the suction nozzle or can be connected in a detachable manner. In particular, different types of suction nozzles can be provided so that different cleaning tasks can be performed in an optimal manner. For example, the suction nozzle can be designed in the form of a surface suction nozzle, a cushion suction nozzle or a crevice suction nozzle.

[0080] Preferably, the first spray hose end is connected to the second handpiece spray channel end in a fluid-tight manner. Therefore, the cleaning fluid can be guided into the handpiece spray channel through the spray hose without loss.

[0081] Advantageously, the fluid connection is arranged or formed on a front device support section, in particular on a front side of the cleaning device.

[0082] In order to avoid twisting of the spray hose, which is disadvantageous when the spray hose is guided on the suction hose, in particular in the suction hose, it is advantageous if the second spray hose end is held on the cleaning device in a rotatable manner, in particular in a rotatable manner relative to the fluid connection about a fluid connection longitudinal axis defined by the fluid connection. Thus, if the first spray hose end is twisted, for example, due to a twisting of the handpiece relative to the first suction hose end in the manner described above, the second spray hose end can be twisted relative to the fluid connection.

[0083] Furthermore, it is advantageous for the operation of the cleaning device if the center of gravity of the cleaning device, in particular independently of the proper filling of the at least one collecting container and / or the cleaning fluid container, is located in the region of the container receptacle, in particular in the middle device carrier section. The cleaning device can thus be balanced in an especially optimal manner. This can be achieved, for example, by a correspondingly balanced arrangement of the components of the cleaning device in the front device carrier section and in the rear device carrier section.

[0084] According to another preferred embodiment, it can be provided that 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 device container receptacle in the spraying and extraction operating position of the cleaning device. This design makes it possible in particular to use the cleaning device in particular as a spraying and extraction device. The container receptacle is therefore used to accommodate the cleaning fluid container and the dirty water container. This design has the advantage that the center of gravity of the cleaning device changes only slightly in its position and positioning when the cleaning fluid is dispensed and received again by the cleaning device and then injected into the dirty water container. During the operation of the cleaning device, the center of gravity gradually shifts slightly from the cleaning fluid container in the direction of the dirty water container.

[0085] It is also advantageous if at least one collecting container is designed in the form of a suction container and is arranged in the container receptacle in the suction operating position of the cleaning device. In particular, such a suction container can completely or substantially completely fill the container receptacle. For example, in a modularly designed cleaning device, it can be inserted into the container receptacle as a replacement for a dirty water container and a cleaning fluid container. With such a suction container, the cleaning device can be used solely for suction, so that the cleaning device can assume the function of a wet / dry vacuum cleaner.

[0086] Advantageously, the suction container defines a suction container volume, the dirty water container defines a dirty water container volume, and the cleaning fluid container defines a cleaning fluid container volume, and the suction container volume corresponds approximately to the sum of the dirty water container volume and the cleaning fluid container volume. Such a design makes it possible, in particular, to use the installation space provided by the container receptacle in an optimal manner with the suction container. Thus, when the cleaning device is operated as a pure suction device, the suction container volume can be maximized.

[0087] In order to configure the cleaning device, in particular, so that when it is operated as a spray extraction device, it is possible to safely and reliably receive all the cleaning fluid contained in the cleaning fluid container after application, it is advantageous if the volume of the cleaning fluid container corresponds to at most approximately 50% of the volume of the dirty water container. Such a size ratio makes it possible, in particular, to arrange or construct a separation device in the dirty water container, which serves to separate liquid and solid dirty water components from the dirty water flow.

[0088] In order to prevent the cleaning fluid from escaping from the cleaning fluid container in an undesired manner, it is advantageous if the cleaning fluid container comprises a cleaning fluid container cap for closing the cleaning fluid container.

[0089] In order to be able to fill the cleaning fluid container with cleaning fluid, for example water, in a simple manner without having to remove the cleaning fluid container cover, it is advantageous if a filling opening is provided or formed on the cleaning fluid container cover.

[0090] Preferably, the cleaning fluid container comprises a closing element for closing the filling opening. It is thus possible to prevent the cleaning fluid from coming out of the filling opening in an undesirable manner. For example, the closing element can be arranged on the cleaning fluid container in a movable or deformable manner so as to move or deform from a position in which the filling opening is open to a position in which the filling opening is closed, and vice versa.

[0091] It is also advantageous if the filling opening has a size and a filling opening cross section which are comparable or substantially comparable to the size and shape of the at least one suction nozzle attachment, in particular the size and shape of the suction nozzle attachment which is constructed in a monolithic manner. Such a design makes it possible in particular to guide the at least one suction nozzle attachment through the filling opening into the cleaning fluid container. In this way, the suction hose can be directly flushed with cleaning fluid and cleaned in this way. In addition, the cleaning fluid for cleaning the cleaning fluid container can be output by means of the suction nozzle through the at least one suction nozzle attachment.

[0092] Cleaning fluid can be removed from the cleaning fluid container in a simple manner if the cleaning fluid container has a container outlet which is fluidically connected to the conveying device, in particular to the suction side of the conveying device.

[0093] Preferably, the container outlet is arranged or constructed on the bottom of the cleaning fluid container. Therefore, the gravity acting on the cleaning fluid can be used to push the cleaning fluid through the container outlet. Therefore, the power of the conveying device for the cleaning fluid can be set to a minimum.

[0094] In order to ensure that cleaning fluid can only come out of the cleaning fluid container when required, it is advantageous if an outlet valve, in particular an outlet valve in the form of a ball valve, is arranged or constructed at the container outlet and that the outlet valve closes when the cleaning fluid container releases the container receptacle and opens when the cleaning fluid container is accommodated in the container receptacle as intended.

[0095] Preferably, a coupling nipple is arranged or configured on the container receptacle, which is used to couple with the container outlet in a fluid-tight manner when the cleaning fluid container is accommodated in the container receptacle as intended. In particular, the coupling nipple can be arranged or configured on the container receptacle bottom, thereby achieving optimal interaction with a container outlet arranged accordingly on the cleaning fluid container.

[0096] In order to improve the handling of the cleaning device, it is advantageous if the coupling nipple comprises a valve actuation mechanism for opening the outlet valve when the cleaning fluid container is accommodated in the container receptacle as intended. For example, the valve actuation mechanism can be designed in the form of a protruding pin which, in the case of a ball valve, moves the ball into the deflected-out position against the action of the preload element when the cleaning fluid container is inserted into the cleaning receptacle.

[0097] If the coupling nipple is connected to the conveying device in a fluid-action manner, the cleaning fluid can be conveyed into the shower hose in a simple manner. Therefore, the conveying device can for example suck the cleaning fluid out of the cleaning fluid container.

[0098] 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, in particular a plurality of, spacers are arranged or formed on the cleaning fluid container, the spacers being supported on a rear partition wall of the rear device carrier section which delimits the container receptacle. The cleaning fluid container can thus be used in particular to press the dirty water container against the device carrier in a defined manner, in particular to bring the dirty water container inlet of the dirty water container into close contact with the dirty water outlet on the container receptacle of the device carrier.

[0099] Preferably, the rear partition wall and the cleaning fluid container wall of the cleaning fluid container comprising at least one spacer are tilted relative to one another at an angle of inclination. This design makes it particularly easy to insert the cleaning fluid container into the container receptacle. In particular, it can have a wedge-shaped profile, which makes it easier to insert the cleaning fluid container into the container receptacle when the dirty water container is already inserted.

[0100] Preferably, the value of the inclination angle is in the range of about 1° to about 5°. Thus, the cleaning fluid container can have a flat wedge shape and can be pushed in a simple manner between the rear partition wall and the dirty water container already placed in the container receptacle.

[0101] Advantageously, the clean fluid container wall of the clean fluid container pointing in the direction of the front housing carrier section and the dirty water container wall of the dirty water container pointing in the direction of the rear housing carrier section abut against each other, in particular flatly, in the spraying operating position. This design has the advantage, in particular, that the dirty water container can be pressed, for example, via the clean fluid container in the direction of the front housing carrier section. For example, corresponding interfaces can be provided on the front housing carrier section for receiving dirty water into the dirty water container. The proposed improvement thus enables an optimal fit of the dirty water container relative to these interfaces, which will be explained in detail below.

[0102] In order to be able to convey dirty water into the dirty water container, it is advantageous if the dirty water container has a dirty water container inlet which is fluidically connected to the suction connection.

[0103] Advantageously, a dirty water outlet is formed on the container receptacle, which is fluidically connected to the suction connection and which is fluidically and fluid-tightly connected to the dirty water container inlet in the spraying and extraction operating position. Thus, for example, dirty water which is guided to the suction hose connection via a suction hose can be introduced into the dirty water container.

[0104] In order to prevent dirty water from escaping in the transition area between the dirty water outlet and the dirty water container inlet, it is advantageous to arrange or construct a sealing element on the dirty water outlet, which is used to seal the dirty water outlet and the dirty water container inlet relative to each other. The sealing element can be injection-molded onto the device carrier, for example, using a thermoplastic elastomer.

[0105] Preferably, the dirty water container comprises an air outlet which is fluidically connected to the suction device. In this way, 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. gaseous dirty water components, can still be sucked by the suction device.

[0106] It is also advantageous if an air inlet is arranged or formed on the container receptacle, which is fluidically connected to the suction device, and if the air outlet is fluidically and fluid-tightly connected to the air inlet in the spray-extraction operating position. Thus, the sucked-in gaseous components of the dirty water can be guided in particular loss-free from the dirty water container through the air outlet and to the suction device through the air inlet.

[0107] It is also advantageous here if a sealing element is arranged or formed at the air inlet, which sealing element serves to seal the air inlet and the air outlet relative to one another.

[0108] Preferably, the air inlet and the dirty water outlet define a plane which is slightly inclined with respect to the direction of gravity. In particular, this plane can also be predetermined by the arrangement of the container receptacle or by the section of the boundary wall on which the air inlet and the dirty water outlet are formed. This makes it possible to achieve an improved fit of the dirty water container in the container receptacle of the cleaning device, in particular with respect to the side walls of the front device carrier section which delimit the container receptacle.

[0109] The cleaning device can be designed to be particularly compact if the dirty water outlet and / or the air inlet is arranged or formed on a side wall of the front device support section which delimits the container receptacle.

[0110] According to a further preferred embodiment, it can be provided that the dirty water outlet defines a dirty water outlet longitudinal axis and the air inlet defines an air inlet longitudinal axis, and that the dirty water outlet longitudinal axis and the air inlet longitudinal axis extend parallel to each other and / or transversely, in particular perpendicularly, to the direction of gravity during proper operation of the cleaning device. Such a design makes it possible in particular to insert the dirty water container into the container receptacle and simultaneously bring the air outlet into engagement with the air inlet on the one hand and the dirty water outlet into engagement with the dirty water container inlet on the other hand in a defined manner.

[0111] The suction device can be realized in a simple manner if the suction device comprises a fan.

[0112] Advantageously, the fan defines a rotation axis which, during proper operation, extends parallel or substantially parallel to the direction of gravity. Thus, in particular, a space-saving arrangement of the suction device in the front device carrier section can be achieved.

[0113] Advantageously, the rotation axis extends transversely, in particular vertically, relative to the dirty water outlet longitudinal axis and / or the air inlet longitudinal axis. Therefore, an optimal positioning of the fan in the housing of the cleaning device can be made possible, in particular independently of the orientation of the cleaning device relative to the direction of gravity.

[0114] Furthermore, according to another preferred embodiment, it can be provided that the cleaning device further comprises a housing, which defines a housing interior, and the suction device outlet on the pressure side of the suction device opens into the interior, in particular in the region of the front housing carrier section. This design makes it possible in particular to minimize the speed of the gas flow and then let it leave through a correspondingly suitable opening on the housing.

[0115] For operating the cleaning appliance, it is advantageous if the cleaning appliance comprises a switching device for activating and deactivating the suction device.

[0116] Preferably, the switch device is configured to activate and deactivate the fluid delivery device, in particular the delivery device. To this end, the switch device can include separate switch elements for the suction device and the fluid delivery device. However, it is also possible to provide only a single switch element in order to simultaneously activate and deactivate the suction device and the fluid delivery device.

[0117] Preferably, the switch device is configured to activate and deactivate the suction device and the fluid output device, in particular the conveying device, simultaneously. Therefore, the user can activate the cleaning device by operating the switch device once, for suction and for dispensing the cleaning fluid.

[0118] In order to enable particularly simple operation of the cleaning device, it is advantageous if the switch device is arranged or constructed on the upper side of the cleaning device. In particular, the switch device can be arranged or constructed on the front device carrier section.

[0119] In order to be able to immediately indicate to the user whether the cleaning appliance is activated or deactivated, it is advantageous if the switching device is designed in the form of a rotary switch or a toggle switch.

[0120] According to a further preferred embodiment, it can be provided that the conveying device and the suction device are dimensioned such that the power consumption of the suction device corresponds to at least approximately five times, in particular at least approximately ten times, the power consumption of the conveying device. This design makes it possible in particular to operate the conveying device permanently, namely even when no cleaning fluid is discharged (because this is prevented, for example, by a valve device on the handpiece).

[0121] In order to facilitate the transport of the cleaning appliance, it is advantageous if the cleaning appliance comprises a handle which is arranged or formed on the rear appliance carrier section and on the front appliance carrier section and comprises a grip section which extends over the container receptacle in the lifting position. This design makes it possible, in particular, for the user to grasp the handle just above the center of gravity of the cleaning appliance, so that the cleaning appliance can be lifted and lifted by the user in an optimally balanced manner.

[0122] Advantageously, the center of gravity of the cleaning device is positioned below the handle section in the lifting position. As described, the carrying comfort of the cleaning device can therefore be improved, because the cleaning device can be held by the user in a maximally balanced manner at the handle section.

[0123] In order to provide the user with direct access to the container receptacle, it is advantageous if the handle can be pivoted about a handle pivot axis which, during proper operation of the cleaning appliance, extends transversely, in particular vertically, to the direction of gravity. The handle can thus be pivoted from a lifting position over the container receptacle into a storage or operating position which releases the container receptacle.

[0124] Preferably, the handle section fully releases the container receptacle in the operating position of the cleaning device and is laterally positioned on the middle device carrier section. Therefore, the container of the cleaning device can be easily inserted into the container receptacle and can also be removed from the container receptacle again.

[0125] Furthermore, in a further preferred embodiment of the cleaning device, in particular also in a cleaning device of the type mentioned at the outset, it can be provided that the cleaning device comprises a separation device for separating liquid dirty bath components entering the at least one collecting container from the dirty fluid flow comprising liquid and gaseous dirty bath components. In particular, the separation device prevents liquid from entering the suction device and damaging it.

[0126] A particularly compact design of the cleaning device can be achieved in particular by virtue of the fact that the separating device is arranged or formed in the at least one collecting container.

[0127] In order to achieve an effective separation between liquid and gaseous dirty water components, it is advantageous if the separation device is arranged or formed on the at least one collecting container between the dirty water container inlet and the air outlet.

[0128] In order to prevent the liquid dirty bath components received in the collecting container from coming out of the collecting container in an undesirable manner, it is advantageous if at least one collecting container comprises a removable collecting container cover. In particular, if the collecting container is designed in the form of a dirty water container, the collecting container cover can be designed in the form of a dirty water container cover.

[0129] Advantageously, the separator device comprises a separation insert which is inserted into the dirty water container and is closed by a dirty water container cover. In particular, the separation insert can be removable from the dirty water container and can be removed from the dirty water container cover, so that the cleaning device and its components can be cleaned in a simple manner.

[0130] Preferably, the separation device comprises a first separation stage, which is connected downstream of the inlet of the dirty water container. Thus, liquid and gaseous dirty water components can be separated from each other in the first separation stage.

[0131] In order to achieve an even better separation of the liquid and gaseous dirty bath components, it is advantageous if the separation device comprises a second separation stage connected downstream of the first separation stage.

[0132] Advantageously, 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 substantially opposite to the direction of gravity during proper operation of the cleaning device. In this way, a first simple separation of liquid and gaseous dirty bath components can be achieved by using gravity to separate them. In particular, the dirty fluid flow can thus be deflected by a deflection angle of approximately 90°.

[0133] Advantageously, a drip opening is formed on the deflection element in the direction of gravity, which is used to discharge liquid dirty bath components into the dirty water container. Thus, in particular, it is possible to prevent liquid dirty bath components from flowing back into the dirty water outlet through the dirty water container inlet.

[0134] In order to reduce the flow velocity of the gaseous dirty bath components, it is advantageous if the flow cross section widens downstream of the deflector element.

[0135] Advantageously, the first separation stage comprises a deflector hood which is open in the direction of gravity and is connected downstream of the deflector element and serves to deflect the dirty fluid flow, in particular gaseous dirty bath components, in the direction of gravity into the dirty water container. In this way, the dirty fluid flow can be additionally deflected by 180° after the deflector element by the deflector hood, wherein liquid and gaseous dirty bath components are separated from one another. Thus, together with the deflector element, the dirty fluid flow can be deflected by a total of 270°, for example by three deflectors which are arranged downstream in sequence and at right angles.

[0136] The compact structure of the cleaning device can be achieved in particular by the dirty water container cover comprising the deflection shield. For example, the dirty water container cover and the deflection shield can be integrally, in particular monolithically, formed.

[0137] According to a further preferred embodiment, it can be provided that the second separation stage comprises a flow chamber for gaseous dirty bath components arranged above the collecting chamber of the dirty water container, the flow chamber having a flow chamber inlet which fluidically connects the collecting chamber and the flow chamber, and having a flow chamber outlet which is fluidically connected to the suction device. This design makes it possible in particular to arrange the flow chamber above the collecting chamber of the dirty water container so that the gaseous dirty bath components can be guided into the flow chamber above the collecting chamber after being introduced into the collecting chamber through the flow chamber inlet and then to the suction device through the flow chamber outlet.

[0138] In order to prevent liquid dirty bath components from penetrating into the flow chamber, it is advantageous if the flow chamber inlet is closed with a gas-permeable but liquid-impermeable partition element.

[0139] A separation of liquid and gaseous dirty bath components can be achieved in a particularly simple manner if the separating element is formed from a nonwoven.

[0140] In order to achieve the lowest possible flow rate of gaseous dirty bath components through the air inlet, it is advantageous if the partition element is curved convexly into the flow chamber against the direction of gravity. Thus, the through opening of the flow chamber inlet can be made as large as possible.

[0141] Preferably, the cross section of the flow chamber inlet is larger than the cross section of the deflector shield. Therefore, the flow velocity in the region of the flow chamber inlet is lower than the flow velocity in the region of the deflector shield. This is particularly advantageous for the separation of liquid and gaseous dirty bath components.

[0142] Furthermore, it is advantageous if the flow chamber outlet opens in the direction of gravity and opens into an upper end of the float shaft extending in the direction of gravity.

[0143] Advantageously, the lower end of the float shaft in the direction of gravity is fluidically connected to the collecting chamber. This makes it possible, in particular, for liquid dirty bath components to flow from the lower end into the float shaft and to fill the float shaft accordingly as the liquid level in the collecting chamber increases. In this way, the liquid dirty bath components in the float shaft can also seal the upper and lower ends of the float shaft from each other.

[0144] In order to prevent coarse dirt from penetrating into the float shaft, it is advantageous if a fluid-permeable filter element is arranged or formed at the lower end of the float shaft.

[0145] In this way, the filter element can be configured in the form of a screen.

[0146] In order to be able to utilize the liquid level in the collection chamber, for example in order to interrupt the suction flow, it is advantageous if a floating element is arranged in the float shaft and is movable parallel to and against the direction of gravity. For example, such a floating element can be raised against the direction of gravity due to a rise in the liquid level in the collection chamber and can be lowered again in the direction of gravity when the collection chamber is emptied.

[0147] In order to prevent as far as possible the possibility that liquid dirty bath components can flow past the float element, it is advantageous if the inner contour of the float shaft corresponds or substantially corresponds to the outer contour of the float element.

[0148] Advantageously, the float element is designed as a sleeve closed on one side and the open end of the sleeve points in the direction of gravity. Such a float element can float on the liquid dirty bath components in the float shaft in a simple and safe manner and can move according to the liquid level in the float shaft.

[0149] It is also advantageous that the float shaft outlet, which is arranged at the upper end of the float shaft and opens in the direction of gravity, is fluidically connected to the air outlet. Therefore, after the gaseous dirty bath component flows through the flow chamber and flows into the upper end of the float shaft, it can flow into the float shaft outlet after another deflection of 180° and leave the dirty water container through the air outlet. Therefore, the second separation stage can enable the suction flow to be deflected by about 360° in total, that is, it is deflected by about 90° when entering the flow chamber through the flow chamber inlet, and further deflected by about 90° when leaving the flow chamber outlet and entering the float shaft, and also deflected by about 180° from the float shaft to the float shaft outlet. In this way, the residues of the liquid dirty bath component can be reliably separated from the gaseous dirty bath component.

[0150] In order to achieve a compact design of the cleaning device, it is particularly advantageous if the cross section of the float shaft outlet is smaller than the cross section of the float shaft.

[0151] Advantageously, the float shaft outlet forms a stop for the float element when it moves against the direction of gravity, and when the float element hits the float shaft outlet, the float element closes the float shaft outlet in the air outlet closing position. This design makes it possible in particular to use the float element as a valve element in order to open or close the float shaft outlet, more precisely to open or close the float shaft outlet depending on the liquid level of the liquid dirty water bath in the dirty water container. Therefore, when the float element closes the float shaft outlet, this is because the liquid level in the dirty water container is too high, and the suction flow will be interrupted. The user can immediately recognize this. In other words, the cleaning device indicates that the dirty water container is full by reducing the suction power.

[0152] According to a further preferred embodiment of the cleaning device, in particular also a cleaning device of the type mentioned at the outset, it can be provided that the cleaning device can include a flow interruption device for interrupting the suction flow generated by the suction device in the interruption position. Such a flow interruption device can be used in particular to indicate to a user that a maximum liquid level has been reached in the dirty water container and that the dirty water container should be emptied.

[0153] In order to interrupt the 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.

[0154] If the valve arrangement comprises a floating element and a float shaft outlet, the valve arrangement can be formed in a simple manner. As described, the floating element can form a valve mechanism which closes or releases the float shaft outlet depending on the liquid level.

[0155] Advantageously, the float element closes the float shaft outlet in the interruption position. The suction flow is thus interrupted, which can be immediately perceived by the user.

[0156] In order to be able to clean the flow chamber, it is advantageous if the dirty water container cover closes the flow chamber against the direction of gravity. Thus, the dirty water container cover can be removed, in particular for cleaning the flow chamber.

[0157] It is also advantageous that the flow chamber is delimited in the direction of gravity by the bottom of the separating insert in the dirty water container. Thus, the bottom separates the flow chamber and the collecting chamber of the dirty water container from each other.

[0158] A compact design of the separating device can be achieved in particular by forming the flow chamber inlet on the bottom of the separating insert.

[0159] In order to improve the handling of the cleaning device, for example when cleaning the cleaning device, 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.

[0160] Preferably, the float shaft comprises a lower shaft section, and the lower shaft section is connected with the upper shaft section along the gravity direction. Therefore, the float shaft is formed by the upper shaft section and the lower shaft section.

[0161] For cleaning the cleaning device, it is advantageous if the upper shaft section and the lower shaft section are designed to be detachably connectable to one another.

[0162] According to a further preferred embodiment of the cleaning container, in particular also in a cleaning container of the type mentioned at the outset, it can be provided that at least one collecting container comprises a collecting container fixing device for fixing a collecting container cover to the at least one collecting container in the closed position. In particular, a collecting container fixing device can be arranged both on the dirty water container and on the suction container in order to fix their respective covers to the mentioned containers.

[0163] In particular, also in the case of cleaning containers of the type mentioned at the outset, it is advantageous if the cleaning fluid container comprises a cleaning fluid container fixing device for fixing the cleaning fluid container cover to the cleaning fluid container in the closed position, so that the cleaning fluid container cover cannot be accidentally removed from the cleaning fluid container.

[0164] Advantageously, the suction container comprises a suction container inlet and a suction container air outlet, wherein the suction container is fluidically connected to the dirty water outlet on the container receptacle in the suction position and the suction container air outlet is fluidically connected to the air inlet on the container receptacle in a fluidically sealed manner. This design 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.

[0165] In order to separate the gaseous and liquid dirty bath components from one another, it is advantageous if the first separation stage on the suction container comprises a deflection element in the form of a baffle pointing in the direction of the suction container outlet and arranged at a distance therefrom, so that the dirty fluid flow can be deflected, for example, by approximately 90° when introduced into the suction container.

[0166] In order to achieve an even better separation of gaseous and liquid dirty bath components, it is advantageous if the second separation stage on the suction container comprises a separation element which closes the air outlet of the suction container.

[0167] If the separating element comprises a filter, liquid and gaseous dirty bath components can be separated from each other in a simple manner. Here, the filter can especially be a nonwoven or a net with sufficiently small meshes.

[0168] Advantageously, the separation element is designed in the form of a sleeve and comprises a sleeve wall with at least one opening, and the filter closes the at least one opening, so that it is possible to achieve that only gaseous dirty bath components can pass through the opening and be guided to the suction device, but not liquid dirty bath components.

[0169] In order to achieve a compact design of the cleaning device, it is particularly advantageous if the separating element projects into the suction container, in particular in a direction transversely, in particular perpendicularly, to the direction of gravity.

[0170] In order to operate the cleaning appliance independently of an electrical network, it is advantageous if the cleaning appliance comprises at least one battery.

[0171] 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 exhausted, it is advantageous if the battery can be connected to the cleaning device in a detachable manner.

[0172] Preferably, the battery is a rechargeable battery so that it can be used multiple times.

[0173] It can also be advantageous, especially in cleaning devices of the type described above, to design the cleaning device modularly and to selectively insert a single suction container on the one hand or a cleaning fluid container together with a dirty water container or a steam generation module with a steam generation device and a fluid container on the other hand into the container receiving portion. Such a design makes it possible, in particular, to use the device carrier section as a basic device and to equip the cleaning device with corresponding modules depending on the cleaning task to be performed. As described above, a spray extraction device or a suction device can be constructed. If a steam generation module including a steam generation device and a fluid container is inserted into the container receiving portion, the cleaning device can also be used as a steam cleaning device.

[0217] Figures 1 to 3 A first exemplary embodiment of a cleaning device, which is designated overall by the reference numeral 10 , is shown schematically.

[0218] The cleaning device 10 comprises a device carrier 12, a suction device 14 arranged on the device carrier 12, a collecting container 16 in the form of a dirty water container 18 and an energy supply connection 20. The collecting container 16 is fluidically connected to the suction device 14, as will be explained in more detail below.

[0219] The cleaning device 10 is designed to be portable and comprises a device base 22 on which four feet are formed.

[0220] During proper operation, the cleaning device 10 stands on a flat or substantially flat surface with the feet 24. The device longitudinal axis 26 defined by the cleaning device 10 during proper operation then extends transversely, in particular perpendicularly, to the direction 28 of gravity.

[0221] In the cleaning device 10 , the collecting container 16 , the suction device 28 and the energy supply connection 20 are arranged or positioned along the device longitudinal axis 26 or substantially along it so that the collecting container 16 is arranged on the device carrier 12 between the suction device 14 and the energy supply connection 20 .

[0222] The device carrier 12 of the cleaning device 10 comprises a container receptacle 30 which is designed to accommodate a collection container 16 in an operable state of the cleaning device 10 .

[0223] In addition, the cleaning device 10 also has a front side 32 and a rear side 34 pointing away from the front side in the opposite direction. Between the front side 32 and the rear side 34, the device carrier 12 includes three device carrier sections, namely a front device carrier section 36, a rear device carrier section 38 and a middle device carrier section 40 arranged between the front and rear device carrier sections 36 and 38.

[0224] The central device support section 40 extends in the direction of the device longitudinal axis 26 , the length of which corresponds to the total length of the front device support section and the rear device support section 38 together.

[0225] The suction device 14 is arranged in a front device carrier section 36 which comprises the front side 32 . The energy supply interface is arranged or formed on a rear device carrier section 38 which comprises the rear side 34 .

[0226] The container receptacle 30 is arranged or formed on the central device carrier section 40 .

[0227] Figures 1 to 3 The exemplary embodiment of the cleaning device 10 schematically shown in FIG. 4 is designed in the form of a spray extraction device 42 and comprises a fluid discharge device, which is designated as a whole by the reference numeral 44, for discharging a cleaning fluid 46. The fluid discharge device 44 comprises a plurality of components.

[0228] The fluid discharge device 44 therefore comprises in particular a cleaning fluid container 48 and a delivery device 50 in the form of a pump 52 , which in the exemplary embodiment shown in the figures is designed in the form of a diaphragm pump 54 .

[0229] In an alternative embodiment, the pump 52 is constructed in the form of a piston pump.

[0230] The transport device 50 is arranged in the front device carrier section 36 .

[0231] The cleaning device 10 further comprises a suction connection 56 arranged or formed on the device support 12 for connection to a suction hose 58 of the cleaning device 10. The suction connection 56 is formed on the front device support section 36, ie, on the front side 32 of the cleaning device 10.

[0232] The suction connection 56 is formed on the front side 32 in the region of a recess 60 , more precisely in the upper region of the cleaning device 10 with respect to the direction of gravity 28 . The recess 60 extends from an upper side 64 of the cleaning device to approximately one third of the total height 62 of the cleaning device 10 .

[0233] The suction hose 58 comprises 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 the connected position as shown in FIG. Figure 1 and Figure 7 As shown in FIG. 1 , the hose coupling 70 is in engagement with a force-locking and / or form-locking manner. In the connected position, the hose coupling 70 is both axially fixed on the suction connection 56 and is prevented from twisting relative to the suction connection 56. This is achieved in particular by the non-circular outer contour of the hose coupling 70.

[0234] A pivotable latching mechanism 72 with a protruding latching nose 74 is formed on the hose coupling 70 , which, in the connected position, engages in a latching recess 76 on the suction connection 56 , which is formed on the front device support section 36 .

[0235] The longitudinal axis of the suction connection 56 extends parallel to the longitudinal axis 26 of the device.

[0236] The cleaning device 10 further comprises a fluid connection 78, which is arranged or formed on the front device carrier section 36, i.e., on the front side 32. The fluid connection is used for connection with a spray hose 80, which comprises a first spray hose end 82 and a second spray hose end 84. The spray hose 80 forms part of the fluid discharge device 44.

[0237] Arranged at the second shower hose end 84 is a connector 86 which engages in a sealing manner in the fluid connection 78 .

[0238] The fluid connection 78 is arranged such that it is surrounded by the suction connection 56. The fluid connection 78 comprises a short sleeve-shaped section, into which the connector 86 engages.

[0239] A holder 88 is formed so as to be surrounded by the suction connection 56 and has two half shells which surround the connection 86 between two annular flanges 90 and 92 formed on the connection 86. The connection 86 and thus the second shower hose end 84 are held in the holder 88 so as to be rotatable about the longitudinal axis of the connection 86.

[0240] The fluid connection 78 is fluidically connected to the conveying device 50, i.e., to the pressure side 96 of the conveying device 50, via a connecting line 94. As described, the second spray hose end 84 is held on the cleaning device 10 so as to be rotatable relative to the fluid connection 78 about a fluid connection longitudinal axis 98 defined by the fluid connection.

[0241] The spray hose 80 is surrounded by the suction hose 58. In the exemplary embodiment shown, the spray hose 80 and the suction hose 58 are designed to be separate from one another. The suction hose 58 is provided with helical reinforcement ribs 100 on its outer side.

[0242] The dirty water container 18 and the cleaning fluid container 48 are arranged together in the container receptacle 30 in the spraying operating position of the cleaning device 10, such as Figure 2 and Fig.10 This is shown schematically and exemplarily in FIG.

[0243] The cleaning fluid container 48 includes a cleaning fluid container cap 102 for closing the cleaning fluid container 48 . Figure 4 Schematically shown in FIG. 4 is a cleaning fluid container 48 and a cleaning fluid container cover 102 in place.

[0244] A filling opening 104 is arranged or formed on the cleaning fluid container cover 102. In addition, the cleaning fluid container 48 also includes a closing element 106 for closing the filling opening 104. The closing element 106 is held movably on the cleaning fluid container cover 102 and is designed in the form of a rubber element and has a protruding gripping tab 108, which enables the closing element 106 to be pulled out of the filling opening 104.

[0245] The filling opening 104 has a circular filling opening cross section.

[0246] Furthermore, the cleaning fluid container 48 comprises a container outlet 110 , which is fluidically connected to the conveying device 50 , namely to the suction side 112 .

[0247] An outlet valve 114 is arranged or constructed on the container outlet 110, more precisely, an outlet valve in the form of a ball valve 116. The outlet valve 114 is designed so that when Figure 4 As shown, when the cleaning fluid container 48 leaves the container receiving portion 30 or is removed from the container receiving portion 30, the outlet valve 114 is closed. Figure 7 As schematically shown in FIG. 1 , when the cleaning fluid container 48 is properly accommodated in the container receptacle 30 , the outlet valve 114 is open.

[0248] The container outlet 110 is designed to cooperate with a coupling socket 118 arranged on the container receptacle 30. Fig. 9 As schematically shown in the enlarged view in FIG. 4 , the coupling nipple serves for fluid-tight coupling to the container outlet 110 when the cleaning fluid container 48 is accommodated in the container receptacle 30 as intended.

[0249] A valve actuation mechanism 120 is arranged on the coupling nipple 118, which serves to open the outlet valve 114 when the cleaning fluid container 48 is accommodated in the container receptacle 30 as intended. The valve actuation mechanism 120 is designed 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 away from 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 coupling nipple 118, engages with the coupling nipple 110. Fig. 9 The outlet valve 4 is shown in its open position.

[0250] The connecting socket 118 is of angled design and is connected via a connecting line 132 to the conveying device 50 , ie to its suction side 112 , in a fluid-tight and seal-tight manner.

[0251] The container receptacle 30 is bounded by a rear partition wall 134 of the rear device carrier section 38. When the cleaning fluid container 48 is inserted into the container receptacle 30, the cleaning fluid container wall 136 pointing in the direction of the rear partition wall 134 is inclined relative to the rear partition wall 134 at an inclination angle 138. In the exemplary embodiment shown, the inclination angle 138 has a value in the range of about 1° to about 5°.

[0252] On the rear partition wall 134, a plurality of spacers 140 in the form of protruding projections are formed on its outer side, and when the clean fluid container 48 is inserted, the spacers abut against the rear partition wall 134 and are supported on it. The purpose of the spacers is to push the clean fluid container wall 142 pointing in the direction of the front device carrier section 36 against the dirty water container wall 144 of the dirty water container 18 in the spraying operating position. The clean fluid container wall 142 and the dirty water container wall 144 are in flat contact with each other. The clean fluid container 48 thus prevents the dirty water container 18 from moving in the direction of the rear housing carrier section 38.

[0253] Furthermore, the cleaning fluid container 48 also includes a cleaning fluid container securing device 146 for securing the cleaning fluid container cover 102 to the cleaning fluid container 48 in the closed position.

[0254] The cleaning fluid container fixing device 146 includes two locking tabs 148, which are protruding from the cleaning fluid container cover 102 and cooperate with corresponding restraining elements on the cleaning fluid container 48 to couple the cleaning fluid container cover 102 to the cleaning fluid container 48 and thereby prevent the cleaning fluid container cover 102 from accidentally loosening from the cleaning fluid container 48.

[0255] The dirty water container 18 serves to receive a dirty bath 150 , in particular a liquid dirty bath component 152 . For this purpose, the dirty water container 18 comprises a collecting chamber 154 .

[0256] The dirty water container inlet 156 of the dirty water container is used to introduce the dirty water 150 into the dirty water container 18. The dirty water container inlet is fluidically connected to the suction connection 56. In addition, a dirty water outlet 158 ​​is also formed on the container receiving portion 30, which is fluidically connected to the suction connection 56. In the spraying operating position, the dirty water outlet 158 ​​is fluidically and fluid-tightly connected to the dirty water container inlet 156, for example, Figure 7 and Fig.10 This can be clearly seen in .

[0257] The dirty water container inlet 156 is formed on an inclined section of a dirty water container wall 160. The inclined section forms an angle 162 with the direction of gravity 28, which has a value in the range of about 2° to about 8°. The section is inclined in such a way that the dirty water container 18 widens in the direction of a dirty water container cover 164 that closes the dirty water container 18.

[0258] A sealing element 166 is arranged or formed at the dirty water outlet 158 ​​, which serves to seal the dirty water outlet 158 ​​and the dirty water container inlet 156 against one another.

[0259] 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 extends parallel to the device longitudinal axis 26 and perpendicular to the direction 28 of gravity.

[0260] Furthermore, the dirty water container 18 comprises an air outlet 172, which is fluidically connected to the suction device 14. An air inlet 174 assigned to the air outlet 172 is arranged or constructed on the container receiving portion 30, and the air inlet is fluidically connected to the suction device 14. In the spraying operating position, the air outlet 172 is fluidically connected to the air inlet 174 in a fluid-tight manner.

[0261] For sealing, a sealing element 176 is arranged or formed on the air inlet 174 in order to seal the air inlet 174 and the air outlet 172 relative to each other. In the illustrated embodiment, the sealing elements 166 and 176 are formed in the form of injection-molded sealing elements made of a thermoplastic elastomer.

[0262] Dirty water outlet 158 ​​and air inlet 174 are arranged or formed on a side wall 178 of front device carrier section 36 that delimits container receptacle 30. Air inlet 174 and air outlet 172 are formed on sections of side wall 178 and dirty water container wall 160 that are inclined at angle 162 relative to gravity direction 28.

[0263] 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 extend parallel to each other and also transversely, ie perpendicularly, to the gravity direction 28 during proper operation of the cleaning device 10.

[0264] The device carrier 12 is designed in a housing-like manner. The front housing part is defined by a front device carrier section 36. The suction device 14 is arranged in the front device carrier section.

[0265] The suction device 14 comprises a fan 182. The fan 182 comprises a fan wheel 184, which is arranged to rotate about an axis of rotation 186. Therefore, the axis of rotation 186 extends parallel or substantially parallel to the gravity direction 28 during the intended operation of the cleaning device 10. Therefore, the axis of rotation 186 is oriented transversely, in particular perpendicularly, to the longitudinal axis 170 of the dirty water outlet and the longitudinal axis 180 of the air inlet.

[0266] The cleaning device 10 comprises a housing 188 which defines an interior space 190. A suction device outlet 192 on the pressure side of the suction device 14 opens into the housing interior space 190, more precisely in the region of the front housing carrier section 36, as shown in FIG. Fig.14 This is shown schematically in .

[0267] The cleaning device 10 further comprises a switch device 194 for activating and deactivating the suction device 14. The switch device 194 is designed in the form of a rotary switch 196. Alternatively, the switch device can also be designed in the form of a toggle switch.

[0268] The switching device 194 is arranged or formed on the top side 64 of the cleaning device 10 , more precisely on the front device support section 36 .

[0269] Furthermore, the switching device 194 is designed to activate and deactivate the fluid discharge device 44 , ie, to activate and deactivate the conveying device 50 .

[0270] In the exemplary embodiment shown in the figures, the switch device 194 is also designed to simultaneously activate and deactivate the suction device 14 and the fluid output device 44 .

[0271] In this manner, all electrical components required for the operation of the cleaning device 10, namely the suction device 14 as well as the transport device 50 and the switch device 190, are arranged or constructed on the front device carrier section 36. They are connected to the energy supply interface 20 via electrical connecting lines (not shown in the drawings) in such a way that the suction device 14 and the transport device 50 can be jointly activated or deactivated by actuating the switch device 194.

[0272] Furthermore, the dimensions of the conveying device 50 and the suction device 14 are determined so that the power consumption of the suction device 14 is at least about five times, in particular at least about ten times, the power consumption of the conveying device 50. In the embodiment shown in the drawings, the power consumption of the suction device 14 is about 100 watts and the power consumption of the conveying device 50 is about 10 watts.

[0273] In order to be able to transport the cleaning device 10, it comprises a handle 198. The handle 198 is designed in the form of a U-shaped bow 200, which has two mutually parallel sides 202 and 204, which are arranged on the one hand on the front device carrier section 36 and on the other hand on the rear device carrier section 38. The sides 202 and 204 are connected to each other via a straight-running handle section 206.

[0274] The handle 198 can be pivoted about a handle pivot axis 208 which, during proper operation of the cleaning device 10, extends transversely, ie vertically, to the direction of gravity 28. Figure 2 In FIG. 1 , the handle 198 is shown in such a way that, in the operating position of the cleaning device 10 , the grip section 206 completely releases the container receptacle 30 and lies laterally against the central device support section 40 .

[0275] The handle pivot axis 208 extends in a center plane 210, in which the device longitudinal axis 26 also extends. The described design allows the handle 198 to be pivoted from the operating position into the carrying position, so that the handle section 206 is also positioned in the center plane 210 and thus passes over the container receptacle 30.

[0276] In the carrying position, the center of gravity 212 of the cleaning device 10 is located below the handle section 206 , ie, in the center plane 210 or substantially in the center plane 210 .

[0277] In order to separate the liquid dirty bath components 152 into the collecting container 16 , ie the dirty water container 18 , and in particular to separate the liquid dirty bath components from the dirty fluid flow 216 comprising the liquid dirty bath components 152 and the gaseous dirty bath components 434 , the cleaning device 10 comprises a separation device 214 .

[0278] In the exemplary embodiment shown in the figures, the separation device 214 is arranged or formed in the collecting container 16 .

[0279] The separation device 214 is arranged or formed in the collecting container 16 between the dirty water container inlet 156 and the air outlet 172 .

[0280] The collecting container 16 comprises a removable collecting container cover 218 , more precisely in the form of a dirty water container cover 164 .

[0281] The separator device 214 comprises a separator insert 220 which is inserted into the dirty water container 18 and is closed on the upper side of the dirty water container by a dirty water container cover 164 .

[0282] The separation device 214 includes a first separation stage 222 and a second separation stage 224. The first separation stage 222 is connected downstream of the dirty water container inlet 156. The second separation stage 224 is connected downstream of the first separation stage 222.

[0283] The first separation stage 222 comprises a deflection element 226 for deflecting the dirty fluid flow 216 flowing into the dirty water container 18. The deflection element 226 is designed in the form of a short pipe section bent by 90°, which, in the proper operation of the cleaning device 10, defines an outlet 228, the flow direction of which is opposite or substantially opposite to the direction of gravity 28. Thus, the dirty fluid flow 216 can be guided against the direction of gravity 28 when entering the dirty water container 18.

[0284] A drip opening 230 is formed at the bottom on the deflection element 226 in the direction of gravity 28 , which serves to drain the liquid dirty bath components 152 into the collecting chamber 154 of the dirty water container 18 .

[0285] The first separation stage 222 comprises a deflection shield 232 which is open in the direction of gravity and is connected downstream of the deflection element 226 for deflecting the dirty fluid flow 216 in the direction of gravity 28 into the collecting chamber 154 of the dirty water container 18. The cross section defined by the deflection shield 232 is twice the cross section of the outlet of the deflection element 226, so that the flow cross section widens after the deflection element 226. Figure 7 This can be seen schematically in .

[0286] The deflector shield 232 is arranged or formed on the dirty water container cover 164. If the dirty water container cover 164 is removed from the dirty water container 18, the deflector shield 232 is also removed at the same time.

[0287] Thus, the first separation stage 222 deflects the dirty fluid flow 216 in the described manner initially by 90° in a direction opposite to the direction of gravity 28 and then immediately further by approximately 180° in a direction parallel to the direction of gravity 28 .

[0288] The separator insert 220 separates the collecting chamber 154 from the flow chamber 234 by a separator insert bottom 236. The separator insert bottom 236 is positioned approximately at the height of the dirty water longitudinal axis 170. The separator insert bottom 236 is opposite a cover wall 238 of the dirty water container cover 164, which closes the flow chamber 234.

[0289] The second separation stage comprises a flow chamber 234 arranged above the collecting chamber 154 of the dirty water container 18 , the flow chamber being used to conduct the gaseous dirty bath components 434 and comprising a flow chamber inlet 240 and a flow chamber outlet 242 .

[0290] The flow chamber inlet 240 is formed in the separation insert bottom 236 and has a substantially rectangular shape. The flow chamber outlet 242 is also formed in the separation insert bottom 236 and has a substantially square shape. The flow chamber inlet 240 fluidically connects the collection chamber 154 and the flow chamber 234. The flow chamber outlet 242 is fluidically connected to the suction device 14.

[0291] The flow chamber inlet 240 is closed by a partition element 244, which is constructed to be air-permeable and liquid-impermeable. The partition element 244 is formed by a nonwoven fabric 246. In particular, Fig.12 It can be clearly seen that the partition element 244 is curved convexly into the flow chamber 234 against the direction of gravity 28. In the exemplary embodiment described, the cross section of the flow chamber inlet 240 is larger than the cross section of the deflector hood 232, so that the gaseous dirty bath components 434 flow through the flow chamber inlet 240 more slowly than in the region of the deflector hood 232.

[0292] The flow chamber outlet 242 opens in the gravity direction 28 and opens into an upper end 248 of a float well 250 extending in the gravity direction 28 .

[0293] The lower end 252 of the float shaft 250 is fluidically connected to the collecting chamber 154. A fluid-permeable filter element 254 is arranged or constructed at the float shaft 250 in the lower end 252 in the direction of gravity 28. The filter element 254 is in the form of a screen 256. Liquid dirty bath components 152 can thus flow through the filter element 254 into the float shaft 250, so that the levels of liquid dirty bath components 152 in the collecting chamber 154 and in the float shaft 250 are substantially the same.

[0294] A float element 258 is arranged in the float shaft 250, which is designed to float on the liquid dirty bath component 152. Depending on the level of the liquid dirty bath component 152 in the float shaft 250, the float element 258 then moves upward or downward in the float shaft 250 against the gravity direction 28 or parallel to the gravity direction.

[0295] The inner contour of the float well 250 is substantially quadrilateral. The outer contour of the float element 258 is substantially circular. Nevertheless, the inner contour of the float well 250 and the outer contour of the float element 258 match each other and substantially correspond to each other, such as Fig.13 This is shown schematically in .

[0296] The floating element 258 is designed in the form of a sleeve 260 which is closed on one side. The open end 262 of the sleeve 260 points in the direction 28 of gravity.

[0297] A float well outlet 264 is arranged at the upper end 248 of the float well 250. The float well outlet essentially comprises a pipe section bent at 90°, which is fluidically connected to the air outlet 172. The float well outlet 264 is open in the direction of gravity 28. The cross section of the float well outlet is smaller than the cross section of the float well 250. As a result, gaseous dirty bath components 434 can flow from the flow chamber 234 through the upper end 248 into the float well 252 and leave through the float well outlet 264 after further deflection of about 180°.

[0298] The cleaning device 10 also includes a flow interruption device 266 for interrupting the suction flow generated by the suction device 14 in the interruption position. The flow interruption device 266 includes a valve facility 268 arranged between the dirty water container inlet 156 and the air outlet 172. The valve facility 268 includes a floating element 258 and a float shaft outlet 264. In the interruption position, the floating element 258 closes the float shaft outlet 264, more precisely when the liquid level of the liquid dirty bath component 152 in the collecting chamber 154 and the float shaft 250 connected to the collecting chamber fluid reaches such an extent that the closed end of the sleeve 260 hits the float shaft outlet 264 and closes the float shaft outlet. Therefore, the float shaft outlet 264 forms a stop 270 for the floating element 258 when moving against the gravity direction 28, wherein the floating element 258 closes the float shaft outlet 264 in the air outlet position.

[0299] The float shaft 250 includes an upper shaft section 272 and a lower shaft section 274. The upper shaft section 272 is arranged or constructed on the separation insert bottom 236. The lower shaft section 274 is connected to the upper shaft section 272 in the gravity direction 28 and extends the upper shaft section to the bottom of the dirty water container.

[0300] The upper shaft section 272 and the lower shaft section 274 are configured to be removably connected to each other. In the embodiment shown in the drawings, a latch connection 276 is schematically shown 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 separation plug 220 as a structural component.

[0301] Furthermore, the collecting container 16 comprises a collecting container fixing device 278 for fixing the collecting container cover 218 on the collecting container 16 in the closed position. Two locking tabs 280 arranged on the sides of the collecting container cover 218 pointing away from each other cooperate with corresponding latching means constructed or arranged on the collecting container 16 so that they are in engagement with each other in the closed position. Figures 1 to 4 It is schematically shown in FIG.

[0302] The energy supply interface 20 of the cleaning device 10 comprises an interface 282 for detachable connection to a battery 284. The interface 282 comprises a battery receptacle 286 for non-positive and / or positive connection to a battery housing 288 of the battery 284.

[0303] The interface 282 is also configured to electrically connect the electrical components of the cleaning device 10 to the battery terminals of the battery 284. In particular, the interface 282 is electrically and effectively connected to the switch contacts of the switch device 194, so that an electrical connection is established by correspondingly operating the switch device 194, so that the battery 284 can supply power to the suction device 14 and the transport device 50 in order to operate them.

[0304] Alternatively or optionally additionally, in an alternative embodiment, it is provided that the energy supply interface 20 comprises a connection device for connecting the cleaning device 10 to the power grid. In this way, the cleaning device can be supplied not only independently of the grid with the battery 284, but also in a grid-dependent manner via a connecting cable with energy provided by the grid.

[0305] The battery 284 can be connected to the cleaning device 10 in a detachable manner. In addition, the battery is also designed in the form of a rechargeable battery 284. This proposed design allows the battery 284 to be removed from the cleaning device 10 when it is empty and to be charged again. In order to immediately continue cleaning, the empty battery 284 can be replaced by another charged battery 284.

[0306] As combined Figures 1 to 18 The cleaning device 10 is designed as a spray extraction device 42. In order to allow the user to quickly and easily clean the object to be cleaned, the cleaning device 10 comprises a suction nozzle 290, which is connected to the first suction hose end 66 or alternatively can be connected in a detachable manner.

[0307] The suction nozzle 290 and the first suction hose end 66 are rotatable in the connecting region 292 about a longitudinal axis 294 defined by the connecting region 292 .

[0308] The suction nozzle 290 comprises a handpiece 296 which is designed to be non-detachable from the suction hose 258. In addition, the suction nozzle 290 comprises a suction nozzle attachment 298.

[0309] Fig. 20 Schematically shown are three suction nozzle attachments 298 , namely a suction nozzle attachment 298 in the form of a surface suction nozzle 300 , a suction nozzle attachment 298 in the form of a crevice suction nozzle 302 , and a further suction nozzle attachment 298 in the form of a crevice suction nozzle 304 .

[0310] The handpiece 296 is coupled to the first suction hose end 66 including the coupling 306 in a freely rotatable manner. For this purpose, a groove 308 in the form of an annular groove extending in the circumferential direction and pointing away from the longitudinal axis 294 of the connection region is formed on the coupling 306, such as Fig.34 and Fig.35 As shown schematically, two guide elements in the form of projections 309 formed on the upper grip part 310 of the handpiece 296 and pointing in the direction of the connecting region longitudinal axis 294 engage in the grooves.

[0311] The upper handle part 310 is designed essentially in the form of a sleeve and has a recess 312 at a lateral region, which is closed by a closure part 314 .

[0312] An opening 316 is formed in the region of the constriction 312, through which the first spray hose end 82 is guided. Thus, the first spray hose end 82 extends into the handpiece 296. In addition, the first spray hose end also extends beyond the first suction hose end 66.

[0313] The first spray hose end 82 is held on the handpiece 296 in a non-twistable manner. This means that when the handpiece 296 is rotated, the first spray hose end 82 is also rotated about the connection region longitudinal axis 294. However, in this way, the entire spray hose 80 is twisted relative to the suction hose 58 in the interior of the suction hose 58. In order to prevent the spray hose 80 and the suction hose 58 from twisting relative to each other, the second spray hose end 84 is held on the fluid connection 78 in a twistable manner as described above.

[0314] A handpiece suction channel 318 is configured on the upper handle portion 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 member 306. Fig. 20 and Fig.26 This is shown by way of example in .

[0315] In the region of the front end of the handpiece 296, a further opening 324 is arranged on the upper grip part 310, through which a first handpiece spray channel end 326 projects and protrudes. The first spray hose end 82 is connected in a fluid-tight manner at the second handpiece spray channel end 328. The second handpiece spray channel end 328 is designed in the form of a sleeve-shaped coupling.

[0316] In addition, a handpiece spray channel 330 extends between the first and second handpiece spray channel ends 326 and 328. In addition, a valve device 332 is arranged or constructed between the first and second handpiece spray channel ends 326 and 328 for opening and closing the handpiece spray channel 330.

[0317] The valve device 332 comprises an actuating element 334 for actuating the valve device 332. The actuating element 334 is designed in the form of a pivot lever 338 which is supported on the handpiece 296, ie, on the closure part 314, in a manner that it can pivot about a pivot axis 336.

[0318] The valve device 332 comprises a valve tappet 340, which opens or closes a valve opening 342 constructed in the handpiece spray channel 330, depending on which position it is in. The valve tappet 340 comprises a deflection surface 344 inclined relative to the longitudinal axis 294 of the connection region, against which a transmission mechanism 348 supported in a bearing sleeve 346 of the valve device 332 in a movement direction inclined relative to the longitudinal axis 294 of the connection region can move. The transmission mechanism is tight relative to the bearing sleeve 346.

[0319] If the swivel lever 338 is pivoted in the direction of the valve device 332, the transmission mechanism 348 is pushed in the direction of the deflection surface 344, so that the front end 350 of the transmission mechanism 348 slides on the deflection surface 344 and the valve tappet 340 moves in the direction of the second handpiece spray channel end 328. A preload element 352 of the valve device 332 is arranged between the valve tappet 340 and the second handpiece spray channel end 328. The preload element 352 is configured in the form of a compression spring 354. It serves to keep the valve device 332 in a basic position in which the handpiece spray channel 330 is closed. Fig.24 and Fig.25 The base position is shown schematically. Fig.26 The open position of the valve arrangement 332 is schematically shown.

[0320] The preload element 352 holds the valve tappet 340 of the valve mechanism 356 forming the valve device 332 in the closed position under preload. As described, the actuating element 334 is configured to cooperate with the valve mechanism 356 to move the valve mechanism 356 against the action of the preload element 352 to an open position deviated from the closed position.

[0321] The closing portion 314 closes the recess 312, which together define a valve receiving chamber 358 for the valve device 332. Thus, the handpiece spray channel 330 extends through the handpiece 296, ie, through the valve receiving chamber 358, substantially parallel to the handpiece suction channel 318.

[0322] The handpiece 296 and the suction nozzle attachment 298 are designed to be connected to each other in a detachable manner. This makes it possible to connect the handpiece 296 to the suction nozzle attachment 298 that is most suitable for the cleaning task to be handled. For this purpose, the suction nozzle 290 includes a suction nozzle connection device 360, which is used to connect the handpiece 296 and one of the suction nozzle attachments 298 in a force-locking and / or form-locking manner in the suction nozzle connection position. This suction nozzle connection position is particularly suitable for Figure 22 to Figure 28 It is schematically shown in FIG.

[0323] In the embodiment of the suction nozzle 290 shown in the figure, the suction nozzle connection device 360 ​​is configured in the form of a latch or snap connection device 362. The suction nozzle connection device 360 ​​includes a first and a second suction nozzle connection element 364 and 366, which are arranged or constructed on the handpiece 296 on the one hand and arranged or constructed on the suction nozzle attachment 298 on the other hand. The two suction nozzle connection elements 264 and 266 are in a force-locking and / or form-locking engagement in the suction nozzle connection position, and in the suction nozzle separation position as shown. Fig. 20 As shown schematically, they are completely separated from each other.

[0324] The suction nozzle connection device 360 ​​includes a socket 368 on the respective suction nozzle attachment 298, which can be moved into the first handpiece suction channel end 320 in a defined rotational position. A second connecting element is arranged or constructed on the socket 368, more precisely in the form of a locking protrusion 372 constructed at the free end of the leaf spring element 370. The free end points in the direction of the handpiece 296. On the first handpiece suction channel end 320, a locking recess 374 is constructed on the flexible unlocking mechanism 376, in which the locking protrusion 372 is accommodated in the suction nozzle connection position. Fig.24 and Fig.26 This can be clearly seen schematically in .

[0325] The unlocking mechanism 376 is constructed on the handpiece 296 in a substantially opposite manner to the actuating element 334. Thus, the user can hold the handpiece 296 with one hand and actuate the actuating element 334, for example, with the middle finger or the index finger. In order to remove the suction nozzle attachment 298 from the handpiece 296, the user can press the unlocking mechanism 376 with his thumb, thereby pivoting the leaf spring element 370 into the handpiece suction channel 318 and thus causing the latching projection 372 to leave the latching recess 374, so that the suction nozzle attachment 298 can be pulled out of the handpiece 296.

[0326] The nozzle attachment 298 includes 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.

[0327] The nozzle attachment 298 is configured so that it and the handpiece 296 fit closely to each other in the suction nozzle connection position. This is achieved in particular by making the second nozzle attachment suction channel end 388 and the first handpiece suction channel end 320 fit closely to each other in the suction nozzle connection position. In addition, the second nozzle attachment spray channel end 384 and the first handpiece spray channel end 326 also fit closely to each other.

[0328] In addition, a spray nozzle 390 is arranged or constructed on the nozzle attachment spray channel 380. In addition, a nozzle attachment spray channel outlet 392 is arranged or constructed on the first nozzle attachment spray channel end 382. In the gap nozzle 302, the spray nozzle 390 is arranged or constructed between the first nozzle attachment spray channel end 382 and the second nozzle attachment spray channel end 384. In the face nozzle 300 and the gap nozzle 304, the spray nozzle 390 forms the nozzle attachment spray channel outlet 392.

[0329] In both the face suction nozzle 300 and the crevice suction nozzle 304 , the spray nozzle 390 is constructed as a separate component and is fastened to the first suction nozzle attachment spray channel end 382 in a close-fitting manner.

[0330] In the face suction nozzle 300, the first nozzle attachment suction channel end 386 extends beyond the first nozzle attachment spray channel end 382. In the face suction nozzle 300, the first nozzle attachment suction channel end 386 is configured in the form of an elongated opening, which extends transversely to the longitudinal axis 294 of the connection area. In addition, the nozzle attachment suction channel 378 is configured in a bent manner. In the face suction nozzle 300, the spray nozzle 390 is independent and is covered by the nozzle attachment suction channel 378 only on one side.

[0331] In the crevice nozzle 304 , the nozzle attachment spray channel 380 extends within the nozzle attachment suction channel 378 .

[0332] In the gap suction nozzle 302 , the spray nozzle 390 is formed in one piece, that is, in a single body. Therefore, it is not necessary to assemble the spray nozzle 390 as in the flat suction nozzle 300 and the gap suction nozzle 304 .

[0333] In the gap nozzle 302, the spray nozzle 390 is configured in the form of a cross-sectional narrowing 394 on the nozzle attachment spray channel 380. Here, the spray nozzle 390 is spaced apart from the first nozzle attachment spray channel end 382 and is therefore arranged between the first nozzle attachment spray channel end 382 and the second nozzle attachment spray channel end 384.

[0334] In the gap suction nozzle 302, the nozzle attachment suction channel cross section of the nozzle attachment suction channel 378 increases continuously from the first nozzle attachment suction channel end 386 toward the second nozzle attachment suction channel end 388. In addition, in the gap suction nozzle 302, the nozzle attachment spray channel cross section of the nozzle attachment spray channel 380 decreases continuously from the first nozzle attachment spray channel end 382 toward the spray nozzle 390, and increases continuously from the spray nozzle 390 toward the second nozzle attachment spray channel end 384. This structural design of the gap suction nozzle 302 enables it to be integrally formed, i.e., monolithically formed as a whole. Therefore, the gap suction nozzle 302 can be produced as an injection molded part in a single injection molding process.

[0335] Furthermore, in the suction nozzle connection position, the second nozzle attachment spray channel end 384 and the first handpiece spray channel end 326 are in close contact with each other.

[0336] Retaining means 396 are arranged laterally spaced apart on the suction nozzle attachment 298 . They are used to connect the suction nozzle attachment 298 to the housing 188 in a detachable manner, more precisely in the region of the rear device carrier section 38 .

[0337] In order to couple the elastically deformable holding means 296, holding means receptacles 398 are respectively formed laterally on the rear device carrier section 38, which can be placed in a force-locking and / or form-locking engagement with the holding means 396. A cross-sectional narrowing 400 is respectively formed on the holding means receptacles 398, on which two lateral projections 402 of the holding means 396 pointing away from each other in opposite directions slide, and the holding means 396 arranged in pairs can be slightly pivoted relative to each other. When the projections 402 engage the cross-sectional narrowing 400 from behind, the holding means 396 will spring back into its basic position again. Fig.17 The holding means 316 is shown before it is brought into engagement with the holding means receptacle 398 . Fig.18 The holding means 396 is schematically shown in engagement with the holding means receptacle 398 .

[0338] like Fig.16As schematically shown in FIG. 2 , one of the two holding mechanism receptacles 398 is used to store one of the two nozzle attachments 298 that is currently connected to the handpiece 296. Thus, the other nozzle attachment 298 in the form of a gap nozzle 302 can be safely held and stored on the other side of the rear device carrier section 38 until it is needed and replaced with the face nozzle 300 on the handpiece 296.

[0339] As mentioned above, the cleaning device 10 forms part of a modular cleaning system 404, generally indicated by reference numeral 204. Fig.42 As schematically shown in FIG, the spray extraction module 428 including the cleaning fluid container 48 and the dirty water container 18 can be selectively placed in the container receptacle 30 forming the module receptacle 440 of the cleaning device 10, that is, in the container receptacle 30 constructed on the device carrier 12. In this way, the cleaning device 10 can be used as a spray extraction device 42.

[0340] Alternatively, a suction module 436 can also be introduced into the container receptacle 30, which comprises only a collecting container 16 in the form of a suction container 406, which alone completely or substantially completely fills the container receptacle 30. Such a combination enables the construction of a cleaning device 10 in the form of a suction device 408, for example in the form of a wet / dry vacuum cleaner.

[0341] Another embodiment of the modular cleaning device 10 provides for the construction of a steam cleaning device 410, namely, by inserting a steam generation module 412 having a steam generation device 414 and a fluid container 416 into the container receptacle 30. For example, water can be poured into the fluid container 416, and the water is vaporized by the steam generation device 414, so that hot steam can be output by the cleaning device 10 (i.e., now as a steam cleaning device 410). The fluid output device described in detail above is used to output steam.

[0342] Figure 36 to Figure 41 Schematically shows an exemplary embodiment of a cleaning device 10 in the form of a suction device 408 . In the suction device 408 , instead of the cleaning fluid container 48 and the dirty water container 18 , only a single suction container 406 is inserted into the container receptacle 30 .

[0343] The collecting container 16 is therefore designed in the form of a suction container 406 in the suction device 408 and is arranged in the container receptacle 30 in the suction operating position of the cleaning device 10 , which thus forms the suction device 408 as described.

[0344] A recess 418 is formed on the underside of the suction container 406, into which the coupling nipple 118 of the cleaning device 10 engages. Since there is no cleaning fluid container 48 and therefore no cleaning fluid 46, the coupling nipple 118 has no effect.

[0345] A suction container inlet 420 and a suction container air outlet 422 are configured on the suction container 406. They are arranged and positioned so that the suction container air outlet 422 is fluidically connected to the air inlet 174 on the container receiving part 30 in a fluid-tight manner. In addition, in the suction position, the suction container inlet 420 is fluidically connected to the dirty water outlet 158 ​​on the container receiving part 30 in a fluid-tight manner. In this way, the sucked-up dirty water 150 enters the collection chamber 154 defined by the suction container 406 through the suction container inlet 420.

[0346] The suction container 406 is closed with the collecting container cover 218 . The collecting container fixing device 278 having two locking tabs 280 is used to securely fix the collecting container cover 218 to the collecting container 16 , ie to the suction container 406 .

[0347] Furthermore, a separation device 214 is arranged or formed on the suction container 406 , which separation device comprises a first separation stage and a second separation stage 224 .

[0348] The first separating stage 222 on the suction container 406 likewise comprises a deflection element 226 in the form of a baffle 424 which points in the direction of the suction container inlet 420 and is arranged at a distance therefrom.

[0349] The second separating stage 224 comprises a separating element 426 which closes the air outlet 422 of the suction container.

[0350] The separation element 426 comprises a filter 428. The separation element is designed in the shape of a sleeve and comprises a sleeve wall 430 having a plurality of large-area cutouts 432 extending on the circumference of the sleeve wall 430. The filter 428 closes these cutouts 432 and is designed to retain liquid but allow air to pass through.

[0351] The separation element 426 is arranged directly in front of the suction container air outlet 422 and is designed coaxially with the air inlet longitudinal axis 180. The separation element 426 thus projects into the suction container 406, more precisely in a direction transverse to the gravity direction 28, ie perpendicular to it.

[0352] The dimensions of the suction container 406 and the dirty water container 18 and the clean fluid container 48 are determined such that the suction container 406 defines a suction container volume, the dirty water container 18 defines a dirty water container volume, and the clean fluid container 48 defines a clean fluid container volume, wherein the suction container volume corresponds approximately to the sum of the dirty water container volume and the clean fluid container volume. In other words, the suction container volume jointly defined by the dirty water container 18 and the clean fluid container 48 is used by the suction container 406.

[0353] Thus, when the cleaning device 10 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 corresponding to at most approximately 50% of the dirty water container volume.

[0354] Another special feature of the cleaning fluid container 48 of the cleaning device 10, in particular for use in conjunction with the crevice suction nozzle 302, is that the filling opening 104 is dimensioned such that the crevice suction nozzle 302 can be introduced into the cleaning fluid container 48 through the filling opening 104. Thus, the cleaning fluid 46 can be sucked directly through the suction nozzle attachment suction channel 378, so that not only the handpiece suction channel 318 but also the suction hose 58 can be cleaned. If necessary, when the operating element 334 of the valve device 332 on the handpiece 296 is actuated, the cleaning fluid 46 can also be discharged into the cleaning fluid container 48 through the spray nozzle 390.

[0355] As already mentioned, the center of gravity 212 of the cleaning device 10 is located in the region of the container receptacle 30, i.e., in particular in the middle device carrier section 40. When the cleaning device 10 is used as a spray extraction device 42, the position of the center of gravity 212 is essentially independent of the proper filling of the collecting container 16 and / or the cleaning fluid container 48. If the cleaning fluid 46 is completely dispensed and received in the collecting container 16, the center of gravity 212 will be slightly displaced in the container receptacle 30 in the direction of the front carrier section 36. Nevertheless, the center of gravity 212 is still positioned below the handle section 206 for optimal handling of the cleaning device 10 in the lifting position, so that the user can lift and lift the cleaning device 10 in a very balanced manner.

[0356] Figure 4 3 shows the flow direction of the cleaning fluid 46 from the cleaning fluid container 48 to the spray nozzle 390 with a solid line. The cleaning fluid is conveyed from the cleaning fluid container 48 to the conveying device 50 via the connecting line 132, and more precisely, the conveying device 50 sucks the cleaning fluid 46 out of the cleaning fluid container 48. The cleaning fluid 46 is conveyed from the conveying device 50 to the fluid interface 78 via the connecting line 94, and then conveyed from the fluid interface to the handpiece 296 via the spray nozzle 80, so that it can be discharged through the spray nozzle 390 of the suction nozzle attachment 298 when the valve device 332 is actuated.

[0357] In contrast, dirty fluid stream 216 (e.g. Figure 4 The dirty bath component 152 is separated in the dirty water container 18 as described, so that the gaseous dirty bath component 434 can flow through the two separation stages 222 and 224 of the separation device 214 in the dirty water container 18 and flow into the air inlet 174 on the container receiving part 30. From there, the gaseous dirty bath component 434 is guided to the suction device 14 through a pipeline arranged in the front device carrier section 36.

[0358] Due to the tight fit of the components connected to one another, good suction results and thus good cleaning results can be achieved even with only low energy consumption of the suction device 14 .
