Description

[0001] CARTRIDGE AND USING A CARTRIDGE

[0002] AND FLUID DEVICE WITH CARTRIDGE

[0003] The invention relates to a cartridge and a use of a cartridge and a fluid device with a cartridge.

[0004] DE 10 2009 013 375 A1 discloses a device and a corresponding method for water treatment at a water outlet fitting in a sanitary area exposed to the outflowing water.

[0005] DE 10 2018 106 446 Al discloses a fragrance cartridge for a steam device.

[0006] The object underlying the invention is to provide and / or improve a cartridge and a use of a cartridge and a fluid device with a cartridge.

[0007] In embodiments of the invention, the underlying object is achieved by a cartridge, in particular a cartridge for a fluid device. The cartridge comprises a container with an interior space, wherein an inlet for a liquid opens into the interior space at an inlet opening and an outlet for a liquid opens into the interior space at an outlet opening, and

[0008] - wherein at least one direct connection in the interior between the inlet opening and the outlet opening is barrier-free at least in an unfilled state of the interior and / or

[0009] - wherein the inlet opening and the outlet opening form a connection, in particular a direct connection, in the interior space between the inlet opening and the outlet opening, being arranged in opposite regions of the interior space in a length-optimized manner.

[0010] In embodiments of the invention, the underlying object is achieved by the use of a cartridge in a fluid device, wherein the cartridge comprises a container with an interior space and wherein in the interior space an inlet at an inlet opening and an outlet at an outlet opening for a liquid open into the interior space and

[0011] - wherein at least one direct connection in the interior between the inlet opening and the outlet opening is barrier-free at least in an unfilled state of the interior and / or

[0012] - wherein the inlet opening and the outlet opening form a connection, in particular a direct connection, in the interior space between the inlet opening and the outlet opening, being arranged in opposite regions of the interior space in a length-optimized manner.

[0013] In embodiments of the invention, the underlying object is achieved by a fluid device comprising a cartridge, wherein the cartridge comprises a container with an interior space and wherein an inlet opens into the interior space at an inlet opening and an outlet opens into the interior space at an outlet opening for a liquid, and

[0014] - wherein at least one direct connection in the interior between the inlet opening and the outlet opening is barrier-free at least in an unfilled state of the interior and / or

[0015] - wherein the inlet opening and the outlet opening form a connection, in particular a direct connection, in the interior space between the inlet opening and the outlet opening, being arranged in opposite regions of the interior space in a length-optimized manner.

[0016] In particular, one advantage of embodiments of the solution according to the invention is that a liquid flowing through the cartridge can flow as unhindered as possible from the inlet opening through the interior to the outlet opening, since the connection between the inlet opening and the outlet opening is barrier-free. Advantageously, this at least reduces or even minimizes flow resistance for the liquid in the interior. In particular, one advantage of embodiments of the solutions according to the invention is that a liquid flowing through the cartridge must flow along the longest possible path through the interior from the inlet opening to the outlet opening, since the inlet opening and the outlet opening are arranged in opposite regions of the interior in such a way that the connection between the inlet opening and the outlet opening is designed to be length-optimized.

[0017] Advantageously, the cartridge is provided and configured for at least partially treating a liquid flowing through the cartridge. Advantageously, a fluid modification material is arranged in the interior space for at least partially treating the liquid when the cartridge is filled, and the interior space is advantageously filled with the fluid modification material. The liquid flowing through the interior space flows around the fluid modification material and is thereby at least partially treated. Therefore, a length-optimized connection between the inlet opening and the outlet opening is advantageous, as this allows the liquid to flow around the fluid modification material and be treated over the longest possible distance.Since a certain flow resistance is already present due to the flow around the fluid modification material, it is advantageous that the connection is otherwise barrier-free, so that the flow resistance in the cartridge for the fluid is kept as small as possible and, ideally, the liquid flowing through the interior is not exposed to any further flow resistance apart from the fluid modification material.

[0018] In particular, the cartridge is provided and designed for a fluid device which is at least partially designed as explained above and below.

[0019] In particular, the cartridge is intended for use in a fluid device that is at least partially designed as explained above and below. To the extent that the cartridge and / or the use and / or the fluid device have at least substantially identical features, these will be described jointly below.

[0020] No further information has been provided so far regarding barrier-free access.

[0021] Preferably, it is provided that at least one connecting space area around the direct connection between the inlet opening and the outlet opening is barrier-free at least in the unfilled state of the interior.

[0022] In particular, the connecting space region extends in a connecting direction from the inlet opening to the outlet opening and extends transversely to the connecting direction.

[0023] Advantageously, the connecting space area extends along a direct connecting line from the inlet opening to the outlet opening.

[0024] For example, the direct connecting line passes through a center point of the inlet opening and through a center point of the outlet opening.

[0025] Advantageously, the connecting space region has, at least for the most part along its extension in the connecting direction, an extent transverse to, in particular at least approximately perpendicular to, the connecting direction, which is at least approximately equal to or greater than an extent of the inlet opening and / or an extent of the outlet opening. It is particularly advantageous if the extent of the connecting space region transverse to the connecting direction is a multiple, for example at least twice and / or at least three times and / or at least four times, the extent of the inlet opening and / or the extent of the outlet opening.In particularly advantageous embodiments, the connecting space region extends at least largely along its extension in the connecting direction transversely, in particular at least approximately perpendicularly, to the connecting direction, for example in at least one direction, up to at least one wall section of the container.

[0026] It is particularly advantageous if the connecting space region extends at least largely along its extension in the connecting direction, for example in several directions running transversely to the connecting direction, up to several different wall sections of the container and in particular extends up to all wall sections of the container enclosing the interior.

[0027] In particular, a feature is formed above and below at least largely in relation to a reference quantity if the feature is formed in at least half, preferably in at least three-quarters, in particular in at least 90%, of the reference quantity and / or is formed in the entire reference quantity except for technically conditioned and / or technically irrelevant restrictions.

[0028] In particular, the connecting space region thus has an extent as explained above, at least for the most part along its extension in the connecting direction, if the connecting space region has such an extent along at least half, preferably along at least three-quarters, for example along at least 90%, of its extension in the connecting direction and / or at least as far as technically possible along its entire extension in the connecting direction. For example, at least one end section of the connecting space region, in particular at an end section located at the inlet opening and / or at an end section located at the outlet opening, such an extension is not possible, since the interior space has a smaller extent in the region of these end sections.In particularly preferred embodiments, the interior is at least largely barrier-free, at least in an unfilled state.

[0029] In particular, an advantage of a barrier-free connecting space area that is as large as possible and in particular of an at least substantially barrier-free interior space is that the liquid can flow as unhindered as possible from the inlet opening to the outlet opening through the interior space.

[0030] In particular, the connection and / or the connection space area and / or the interior space is barrier-free if at least no elements of the container and in particular no elements of the cartridge and preferably no further elements are arranged therein.

[0031] No further information has been provided regarding the fluid modification material.

[0032] In particular, it is provided that in a filled state of the interior space, the interior space is at least partially, preferably at least largely, filled with the fluid modification material.

[0033] In particular, the fluid modification material is designed for the physical and / or chemical modification of the liquid flowing through the cartridge.

[0034] In particular, it is intended that the liquid flowing through the cartridge comprises at least water. For example, at least one additive is added to the water.

[0035] Advantageously, the fluid modification material at least treats the water. In particular, it is provided that the fluid modification material is designed at least partially for the at least partial, in particular physical and / or chemical, removal of substances from the liquid, in particular for the at least partial decalcification of the water.

[0036] In particular, the fluid modification material can have a wide variety of components.

[0037] Preferably, the fluid modification material comprises at least one resin.

[0038] It is particularly advantageous if the fluid modification material is a granular medium.

[0039] In particular, in the filled state, the interior of the container and in particular the otherwise barrier-free connection between the inlet opening and the outlet opening and its connecting space area are at least partially, preferably at least largely filled with the preferably granular fluid modification material.

[0040] In particular, the granular medium has the advantage that it has a large surface area for interaction with the liquid for its processing and can be favorably flowed around by the liquid.

[0041] For example, filling the interior with the granular medium and / or removing the used granular medium from the interior is easily possible.

[0042] Further details regarding the design of the container and the arrangement of the inlet and outlet openings have not yet been provided. In particular, the container comprises a plurality of wall sections, and the plurality of wall sections define the interior space. Preferably, the container is formed essentially from the plurality of wall sections.

[0043] In particular, the plurality of wall sections each extend in a respective extension surface and have a respective thickness transverse to their respective extension surface.

[0044] In particular, the plurality of wall sections each have an inner wall surface and an outer wall surface.

[0045] Advantageously, the respective inner wall surface of a wall section delimits at least part of the interior space.

[0046] Advantageously, the inner wall surfaces are flat surfaces, in particular without any parts protruding into the interior.

[0047] Preferably, no further element of the container is arranged on at least one wall surface, advantageously on at least some, in particular on at least most, for example on all, of the inner wall surfaces of the plurality of wall sections.

[0048] It is particularly advantageous if an overall surface, which is formed from the inner wall surfaces of the several wall sections, completely encloses the interior space.

[0049] Preferably, no further element of the container is arranged in the space enclosed by the total area.

[0050] Advantageously, this allows the liquid to flow as unhindered as possible through the interior space enclosed by the inner wall surfaces. In particular, the outer wall surfaces of the multiple wall sections form a respective outer side of the container.

[0051] Advantageously, each of the plurality of wall sections separates the interior of the container from the surroundings of the container.

[0052] In particular, the outer wall surface and the inner wall surface of a wall section are opposite wall surfaces of this wall section in a thickness direction of the wall section, wherein the thickness of the wall section is measured in particular in the thickness direction.

[0053] In particular, the container has several edge areas.

[0054] In particular, two wall sections are arranged next to each other in a respective edge area.

[0055] In particular, the container has several corner areas.

[0056] In particular, three wall sections are arranged next to each other in each corner area.

[0057] In particular, a respective wall section extends in its extension area up to at least one end region and in particular between several end regions.

[0058] In particular, of an extension of a wall section in one direction in the extension area, at most 30% is located in an end region of the wall section.

[0059] Preferably, at least one wall section, advantageously each of at least some, for example each of all, of the plurality of wall sections extends in a respective longitudinal direction between two respective longitudinal end regions and in a respective transverse direction between two respective transverse end regions. In particular, the longitudinal direction and the transverse direction of a wall section extend at least approximately perpendicular to one another.

[0060] In particular, at least one wall section is rectangular in shape, and advantageously at least some of the wall sections are rectangular in shape. For example, the length of a wall section in its longitudinal direction is equal to or greater, for example, at least 30% greater, than its length in its transverse direction.

[0061] Advantageously, at least some, for example all, of the plurality of wall sections extend flatly at least between their respective end regions.

[0062] Advantageously, the wall sections of the container have curvatures at most in edge areas and / or corner areas.

[0063] In some embodiments, the container is preferably cuboid-shaped with substantially rectangular wall sections. For example, at least some edge regions are curved.

[0064] In particular, a wall section is arranged in at least one end region on at least one further wall section, and the at least two wall sections form a common edge region. Advantageously, each of the wall sections is arranged in its respective end regions on at least one respective further wall section, wherein the respective wall section forms a respective edge region with the at least one further wall section.

[0065] In particular, some, for example three, edge regions meet one another and form a respective corner region of the container, wherein in this corner region the some, for example three, wall sections, which are arranged in at least one of the several edge regions with a further wall section, are arranged next to one another.

[0066] Advantageously, the inlet opening is formed in an inlet corner region of the container. Preferably, the outlet opening is formed in an outlet corner region of the container.

[0067] In advantageous embodiments, the inlet corner region (in which the inlet opening is formed) and the outlet corner region (in which the outlet opening is formed) do not have a common wall section. In particular, the wall sections that are arranged adjacent to one another in the inlet corner region (in which the inlet opening is formed) and the wall sections that are arranged adjacent to one another in the outlet corner region (in which the outlet opening is formed) are different wall sections.

[0068] In particularly preferred embodiments, the inlet corner region (in which the inlet opening is formed) and the outlet corner region (in which the outlet opening is arranged) are the two corner regions of the container which are at the greatest distance from each other in the interior space.

[0069] In advantageous embodiments, the container expands at least substantially in one expansion plane and in one height direction, wherein the height direction runs at least approximately perpendicular to the expansion plane. In particular, the expansion plane is spanned by two expansion directions. The two expansion directions run, for example, at least approximately perpendicular to each other.

[0070] In advantageous embodiments, the extension of the container in the vertical direction is smaller, for example, at least 30% smaller, than the extension of the container in at least one, preferably both, of the two extension directions. For example, one of the two extension directions runs in the direction in which the container has its smallest extension relative to the extension plane, and / or one of the two extension directions runs in a direction in which the container has its greatest extension relative to the extension plane.

[0071] Preferably, the container has two wall sections arranged oppositely in the height direction.

[0072] Advantageously, the two wall sections arranged oppositely in the height direction extend at least for the most part, for example at least between their respective end regions, parallel to the plane of extension of the container.

[0073] Preferably, the two wall sections arranged oppositely in the height direction have a substantially identical shape, which in particular defines a base area of ​​the container.

[0074] In particular, at least one lateral wall section extends between the two wall sections arranged opposite each other in the vertical direction. For example, several lateral wall sections are provided. Preferably, one of the extension directions of a lateral wall section runs at least approximately parallel to the vertical direction.

[0075] Preferably, the inlet opening and the outlet opening are formed on opposite sides of the interior space in the height direction.

[0076] In particular, the inlet opening is formed in one of the two wall sections, which are arranged opposite to one another in the vertical direction, and / or the outlet opening is formed in one of the two, for example, in the other of the two wall sections, which are arranged opposite to one another in the vertical direction. For example, it is advantageous that little installation space is required for the cartridge between the inlet and the outlet, since these can be arranged opposite to one another in terms of the small vertical direction, but nevertheless, due to the length-optimized arrangement of the inlet opening and the outlet opening, the liquid flowing through the cartridge is still processed along the longest possible path in the interior of the cartridge.

[0077] For example, the cartridge can be arranged in a space-saving manner between a unit which can be and / or is connected to the inlet, in particular a water tank, and a unit which can be and / or is connected to the outlet, for example.

[0078] It is particularly advantageous if the inlet, in particular an inlet nozzle thereof, extends vertically away from the container. In particular, the inlet, in particular its inlet nozzle, extends away from the wall section in which the inlet opening is formed.

[0079] Preferably, the outlet, for example an outlet nozzle thereof, extends vertically away from the container. In particular, the outlet, in particular its outlet nozzle, extends away from the wall section in which the outlet opening is formed.

[0080] For example, this enables a compact installation situation for the cartridge. One advantage of this is that an installation space that exists transversely to the vertical direction can be used for the expansion of the container, allowing the interior space and the length-optimized connection between the inlet opening and the outlet opening to be designed as large as possible. Advantageously, a region of the interior space into which the inlet opening opens and a region of the interior space into which the outlet opening opens are located opposite each other in the interior space in at least one, preferably in both, of the two expansion directions and / or in the vertical direction of the container.

[0081] It is particularly advantageous if the region of the interior space into which the inlet opening opens and a region into which the outlet opening opens are opposite regions with respect to a direction in which the interior space has at least approximately its greatest extent.

[0082] In particular, the direction in which the interior space at least approximately has its greatest extent runs diagonally to the height direction and / or diagonally to at least one, preferably both, of the two extension directions of the container. In particular, the direction in which the interior space at least approximately has its greatest extent runs along a spatial diagonal of the interior space.

[0083] Advantageously, the area of ​​the interior into which the inlet opening opens and the area of ​​the interior into which the outlet opening opens are located at opposite ends of a spatial diagonal of the interior.

[0084] In advantageous embodiments, in at least one projection plane, a region in which a projection of the inlet opening lies and a region in which a projection of the outlet opening lies are opposite regions. In particular, the two regions are opposite regions with respect to a projection of at least one of the two extension directions and / or with respect to a projection of the height direction and / or with respect to a projection of the direction in which the interior space has at least approximately its greatest extent and / or with respect to a projection in at least one extension direction of at least one wall section in which the inlet opening or the outlet opening is formed. In particular, the two opposite regions are opposite regions of the projection of the interior space. In particular, this is the case for at least one, preferably for at least several, of the projection planes defined as follows:

[0089] In particularly advantageous embodiments, the interior is designed to be barrier-free, such that, in at least one projection plane, only those areas of the interior that are barrier-free to the fluid are projected onto an area between the projection of the inlet opening and the projection of the outlet opening. This is particularly the case for at least one, preferably for at least several, of the projection planes defined as follows:

[0090] - a projection plane runs at least approximately perpendicular to the height direction and / or - a projection plane runs at least approximately perpendicular to one of the two extension directions and / or

[0091] - a diagonal of the interior runs through a projection plane and / or

[0092] - a projection plane is spanned by an extension direction of one wall section and an extension direction of another wall section, wherein these two wall sections are arranged next to one another in an edge region and / or in a corner region and the inlet opening or the outlet opening is arranged in this edge region and / or corner region, and wherein the two extension directions that span this projection plane run away from the region in which the inlet opening or the outlet opening is formed and are, for example, those extension directions of these wall sections in which the respective wall section extends furthest from the region in which the inlet opening or the outlet opening is formed.

[0093] Preferably, the cartridge is designed for an at least approximately vertical orientation. Conveniently, the cartridge is used in an at least approximately vertical orientation. Preferably, the cartridge is arranged in an at least approximately vertical orientation in the fluid device.

[0094] In particular, the proper vertical alignment provides for at least one of the following:

[0095] - that the outlet opening is arranged in a lower region of the interior relative to a vertical direction of the device and / or relative to the direction of gravity and / or that the inlet opening is arranged in an upper region of the interior relative to a vertical direction of the device and / or relative to the direction of gravity, and / or - that the height direction of the container is oriented at least approximately perpendicular to a vertical direction of the device and / or to the direction of gravity, and / or

[0150] The device 100 comprises at least one device module 112 and / or a handle module 114 and / or at least one application module 116 and / or at least one extension module 118.

[0151] In variants of the exemplary embodiment, more or fewer modules can also be provided. For example, in some variants, the device module 112 integrally comprises a handle unit, and in this case, for example, no separate handle module 114 is provided. For example, in some variants, the device module 112 also comprises at least one application unit, and thus, in particular, no separate application module 116 is provided.

[0152] In particular, the device 100 can be configured for different applications through the various device configurations 105.

[0153] In particular, in at least one device configuration 105, here in the device configurations 1051, 11, 111 shown as examples in Fig. 1, the device is a long handset. In a device configuration 105 corresponding to a long handset, at least one extension module 118 is used, which is attached to at least the device module 112 and / or the handle module 114 and / or the application module 116.

[0154] For example, in a device configuration 105 corresponding to a long handset, here in the device configuration 1051, the device module 112 and the application module 116 are fastened to one another and at least one extension module 118, for example two extension modules 1181,11, are inserted between the device module 112 and the handle module 114.

[0155] For example, in a device configuration 105 corresponding to a long handset, here in the device configuration 105II, at least one extension module 118, here the extension module 11811, is inserted between the device module 112 and the application module 116, and at least one extension module 118, here the extension module 118I, is inserted between the device module 112 and the handle module 114.

[0156] For example, in a device configuration 105 corresponding to a long handset, here in device configuration 105III, the device module 112 and the handle module 114 are fastened to one another and at least one extension module 118 is inserted between the device module 112 and the application module 116, here for example the two extension modules 1181 and 118II.

[0157] In particular, a device configuration 1051,11,111 corresponding to a long handheld device is advantageous in order to increase the direct radius of action within which the user can use the device 100. For example, a long handheld device is advantageous because it allows the user to perform functions of the device 100 in different and / or at least in a specific body position, in particular in an upright body position. In particular, the device 100 in a device configuration 105 in which it is a long handheld device is advantageous in order to allow a user to clean a floor and / or wall areas of different heights in an upright body position.

[0158] In particular, it is advantageous that, depending on the device configuration 1051,11,111, the device module 112 can be arranged at a different distance from the handle module 114 and / or from the application module 116 in order to achieve handling adapted to the application and / or a more user-friendly arrangement of the modules. In particular, in a device configuration 105, here in the device configuration 105IV shown as an example in Figures 2 and 3, the device 100 is a small handheld device, wherein in this device configuration 105IV the device module 112 is assembled only with the handle module 114 and the application module 116.

[0159] For example, a device configuration 105IV corresponding to a small handheld device is advantageous in that a user is provided with a handy and compact device.

[0160] For example, in some variants, a device configuration 105V is provided in which at least one extension module 118 is inserted between the device module 114 and the application module 116, but no handle module 114 is provided in this device configuration 105V, as shown by way of example in Fig. 4.

[0161] For example, such a device configuration 105V without a handle module 114 is advantageous if the device module 114 can be placed in one place and / or the application module 116 can be grasped by a user in order to be able to act on an object and / or a surface and / or another thing with the device 100.

[0162] The device module 112 comprises at least partially, preferably at least largely, the device technology required for the at least one function of the device 100. For example, the device technology provided by the device module 112 comprises at least one functional unit for a function of the device 100 and / or a controller, in particular an electronic controller, for controlling the device technology, in particular for controlling the at least one functional unit, and / or display elements and / or operating elements and / or a power supply unit. An advantageous exemplary embodiment of a device module 112 is described in more detail below. In advantageous variants of the exemplary embodiment, the device 100 is a fluid device, and at least one functional unit of the device module 112 is a hot fluid generation unit.

[0163] The handle module 114 comprises at least one element that forms a handle. An advantageous embodiment of a handle module 114 is explained in more detail below.

[0164] The application module 116 is designed to act on an object, in particular on an object and / or a surface, according to at least one function of the device 100.

[0165] In particular, the application module 116 of a device 100 configured as a fluid device is designed for applying a hot fluid, for example, for cleaning and / or ironing. For this purpose, the application module 116 comprises at least one outlet opening for the hot fluid. For example, the application module comprises at least one outlet nozzle, preferably for a targeted and / or pressurized application of the hot fluid.

[0166] In some advantageous variants, an application module 116 is configured for a cleaning function. In particular, at least one cleaning element can be arranged on the application module 116 and / or, for example, the application module 116 comprises at least one cleaning element. For example, at least one cleaning element is a cleaning cloth and / or a cleaning brush.

[0167] For example, in some variants, an application module 116 is designed for treating an item, for example, for ironing garments. For the ironing function, a corresponding application module 116 preferably has a particularly metallic ironing surface, in which outlet openings for the hot fluid are advantageously formed. In particular, at least one extension module 118, in particular the plurality of extension modules 118, is provided and designed to increase the direct radius of action within which a user can use the device 100 and / or to allow the user to use the device 100 in a more comfortable, particularly upright, body position.

[0168] In particular, an extension module 118 is formed at least largely from an extension module body. Conveniently, the extension module body extends longitudinally between two ends. In particular, a fastening unit 132 is arranged at each of the two ends of the extension module body.

[0169] In some variants, at least one extension module 118 is configured to functionally connect the device module 112 and the application module 116 when this extension module 118 is inserted between the device module 112 and the application module 116. In particular, at least one extension module 118 is configured to functionally connect the device module 112 and the handle module 114 when this extension module 118 is inserted between the device module 112 and the handle module 114.

[0170] For example, in a device 100 designed as a fluid device, at least one extension module 118 is designed to guide a fluid, in particular a hot fluid, from the device module 112 to the application module 116, and in particular, it comprises a line for a fluid for this purpose. For example, in a simple variant, a cavity in the extension module body forms at least a large part of the line for the fluid, with this cavity extending continuously between the two ends of the extension module body.

[0171] In some inexpensive variants, an extension module 118 does not have to functionally connect at least the handle module 114 and the device module 112 and only has to fulfill the extension function, so that the extension module 118 can be designed in a structurally simple manner.

[0172] For example, this is advantageously provided if no device technology is formed in the handle module 114 or if device technology formed in the handle module 114, for example at least one operating element, communicates wirelessly with the device technology formed in the device module 112.

[0173] In some advantageous extension modules 118, at least their extension module body is rigidly constructed, and advantageously, the respective fastening unit is rigidly arranged at the corresponding end of the extension module body. Such rigid extension modules 118 are particularly advantageous for device configurations 1051, 111, 111 corresponding to a long handheld device, as illustrated by way of example in Fig. 1.

[0174] In some advantageous extension modules 118, their extension module body is at least partially, for example completely, flexible between its two ends, as is exemplified in the embodiment shown in Fig. 4. For example, this can achieve favorable handling for some applications, for example of the application module 116, at least largely independent of any concomitant movement of the device module 112.

[0175] Although a flexible extension module 118 is shown in the embodiment shown in Fig. 4 for a device configuration 105V without a handle module 114, in some applications an inserted flexible extension module 118 in a device configuration 105 with a handle module 114 may be advantageous.

[0176] In particular, each of the modules 112, 114, 116, 118 has at least one fastening unit 132, with which the corresponding module 112, 114, 116, 118 and another module 112, 114, 116, 118 can be fastened to one another. In particular, the device module 112 has two fastening units 132. In particular, a handle-side fastening unit 132 is designed for assembly with the handle module, either by directly fastening the two modules to one another or with at least one extension module 119 inserted and fastened between them. In particular, an application-side fastening unit is designed for assembly with at least one application module 116, either by directly fastening the two modules to one another or with at least one extension module 119 inserted and fastened between them.

[0177] Each of the extension modules 118 advantageously has two fastening units 132 in order to be able to be fastened to two further modules.

[0178] In particular, the handle module 114 has exactly one fastening unit 132.

[0179] In particular, the application module 116 has exactly one fastening unit 132.

[0180] In particular, the fastening units 132 each have at least one released state and at least one attached state. In the released state, one fastening unit 132 is not attached to another fastening unit of another module 132, and the two modules are detached from each other unless they are attached to each other with other fastening units. In an attached state, two fastening units 132 are attached to each other, and the two modules comprising the two fastening units 132 are attached to each other.

[0181] In particular, two different types of fastening units 132 are provided, for example, a first type 132a and a second type 132b, wherein a fastening unit 132, 132a of one type and a fastening unit 132, 132b of the other type can be fastened to one another. In particular, the handle module 114 has a fastening unit 132 of one type, for example, a fastening unit of the first type 132a, and the handle-side fastening unit 132 of the device module 112 is of the other type, for example, a fastening unit of the second type 132b, or vice versa.

[0182] In particular, the application module 116 has a fastening unit 132 of one type, for example a fastening unit of the second type 132b, and the application-side fastening unit 132 of the device module 112 is of the other type, for example a fastening unit of the first type 132a, or vice versa.

[0183] In some advantageous variants, the fastening units 132 of the handle module 114 and the application module 116 are of the same type, for example a fastening unit of the first type 132a each, and accordingly the handle-side and application-side fastening units of the device module 112 are of the same type and of a different type than the handle module 114 and the application module 116.

[0184] In some variants, the fastening units 132 on the handle module 114 and on the application module 116 are of different types and thus the handle-side fastening unit 132 and the application-side fastening unit 132 on the device module 112 are also of different types.

[0185] Advantageously, a fastening unit of one type, here for example a fastening unit of the first type 132a, has a fastening receptacle 136 and a fastening unit 132 of the other type, here for example a fastening unit of the second type 132b, has a fastening counterpart 138, as shown by way of example in Figures 5 and 6.

[0186] The fastening counterpart 138 is designed to be received in the fastening receptacle 136 in the fastened state. In particular, in a released state of a fastening unit 136, no fastening counterpart 138 of another fastening unit 132 is arranged and received in its fastening receptacle 136. In particular, in a released state of a fastening unit 132, its fastening counterpart 138 is not arranged and received in any fastening receptacle 136 of another fastening unit 132.

[0187] In particular, a respective fastening mechanism is provided, which is at least partially formed on each of the fastening units 132. In particular, the fastening mechanism is designed to hold fastening units 132 fastened to one another in the fastened state. In particular, in the fastened state, the fastening mechanism holds the fastening counterpart 138 in the fastening receptacle 136, in which the fastening counterpart 138 is received. Advantageously, the fastening mechanism is a releasable fastening mechanism, and in a release position of the fastening mechanism, the fastening units 132 fastened to one another can be separated from one another and placed in their released state. For example, in the release position of the fastening mechanism, the fastening counterpart 138 can be removed from a fastening receptacle 136 in which the fastening counterpart is received.

[0188] For example, the fastening mechanism is a locking mechanism. A fastening unit 132 of one type has a locking element, which is received in a locking receptacle of a fastening unit 132 of the other type for fastening. In particular, the locking element can be pushed out of the locking receptacle so that the locking mechanism is in the release position.

[0189] Preferably, the device 100, in particular at least most of the device module 112, comprises a detection device 152 for detecting at least some device configurations 105. In particular, the sensor 156 is assigned to a fastening unit 132 and in particular arranged therein.

[0190] Conveniently, at least one fastening unit 132 of the device module 112, in particular at least the handle-side fastening unit 132, comprises a sensor 156, as shown by way of example in Figures 5 and 6.

[0191] In some variants, at least one fastening unit of at least the handle module 114 and / or the application module 116 and / or at least one extension module 118 comprises a sensor 156.

[0192] Advantageously, at least one sensor 156 and in particular the fastening units 132 of at least some of the further modules are designed such that the sensor 156 can at least partially detect whether the fastening unit 132 assigned to it is in a fastened state with another fastening unit 132.

[0193] In advantageous variants, two subtypes of corresponding fastening units 132 are provided for at least one fastening unit 132 assigned to a sensor 156. The corresponding fastening units 132 of the two subtypes are fastening units 132 that can be fastened in a fastened state to the fastening unit 132 assigned to a sensor. For example, the corresponding fastening units 132 of the two subtypes are of a different type than the fastening unit 132 with the associated sensor 156.

[0194] The fastening units 132 of the two subtypes differ in such a way that a detection result of the sensor 156 in a fastened state of the fastening unit 132 assigned to it with a fastening unit 132 of one of the two subtypes is different from a detection result of the sensor 156 in a fastened state of the fastening unit 132 assigned to it with a fastening unit 132 of the other of the two subtypes.

[0195] Conveniently, the corresponding fastening units 132 of one subtype are provided for modules of at least one category, and the corresponding fastening units 132 of the other subtype are provided for modules of the remaining categories. In particular, the module categories are the device module 112, the handle module 114, at least one application module 116, and the extension modules 118.

[0196] Advantageously, at least one sensor 156 can thus distinguish between a fastened state of the fastening unit 132 assigned to it with a corresponding fastening unit 132 of one of the two subtypes, on the one hand, and other states of the fastening unit 132 assigned to it. Advantageously, it can thus be detected whether the module with the fastening unit 132 assigned to the at least one sensor is fastened to a module of at least one category.

[0197] In advantageous variants, at least one sensor 156 is triggered in a fastened state of the fastening unit 132 assigned to it with a corresponding fastening unit 132 of one of the two subtypes, while this at least one sensor 156 is not triggered in a fastened state of the fastening unit 132 assigned to it with a corresponding fastening unit 132 of the other subtype and in a released state of the fastening unit 132 assigned to it.

[0198] In some variants, a detection result of at least one sensor 156 is different in at least three states of the fastening unit 132 assigned to it, namely in a fastened state with a corresponding fastening unit 132 of one subtype, a fastened state with a fastening unit 132 of the other subtype and in a released state, so that at least these three different states can be distinguished based on the detection result of this at least one sensor 156.

[0199] In advantageous variants, the handle-side fastening unit 132 of the device module 112 and a sensor 156 assigned to it, as well as the fastening unit 132 of at least most of the other modules, are designed such that this sensor 156 can distinguish between a fastened state of the handle-side fastening unit 132 assigned to it with a fastening unit 132 of an extension module 118 on the one hand and other states of the handle-side fastening unit 132 assigned to it on the other hand.

[0200] In some advantageous variants, the handle-side fastening unit 132 and a sensor 156 assigned to it, as well as the fastening units 132 of at least most of the other modules, are designed such that this sensor 156 can at least distinguish between a fastened state of the handle-side fastening unit 132 assigned to it with a fastening unit of the handle module 114 on the one hand and other states of the handle-side fastening unit 132 assigned to it on the other hand.

[0201] In some advantageous variants, the application-side fastening unit 132 and a sensor 156 assigned to it, as well as the fastening units 132 of at least most of the other modules, are designed such that this sensor 156 can at least partially distinguish between different states of the application-side fastening unit 132 assigned to it, in particular at least between a fastened state with a fastening unit of an extension module 118 and / or a fastened state with a fastening unit 132 of at least one application module 116 and / or a detached state.

[0202] In some variants in which a plurality of application modules 116 are provided, the plurality of application modules 116 have, for example, different subtypes of fastening units 132, so that in the case of at least one fastening unit 132 with an associated sensor 156, for example in the case of a fastening unit 132 of an extension module 118 and / or in the case of the application-side fastening unit 132 of the device module 112, this associated sensor 156 can distinguish between the attached states of the fastening unit 132 associated with it with fastening units 132 of different application modules and can thus be recognized which of the different application modules 116 is used in the device configuration 105.

[0203] In some variants, the fastening unit 132 of the handle module 114 and a sensor 156 associated with it, as well as the fastening units 132 of at least most of the other modules, are designed such that this associated sensor 156 can distinguish at least between some states of the fastening unit 132 associated with it, in particular between a fastened state with a fastening unit 132 of an extension module 118 and / or a fastened state with a fastening unit 132 of the device module 112 and / or a released state.

[0204] In particular, a sensor 156 has a detection area 162 in the fastening unit 132 assigned to it, as shown by way of example in Figures 5 and 6.

[0205] Advantageously, at least some of the corresponding fastening units 132 have an element 164 to be detected, wherein in a fastened state of the fastening units 132, the element 164 to be detected is arranged in the detection area 162 and is thus detected by the sensor 156.

[0206] In particular, only corresponding fastening units 132 of one subtype have an element 164 to be detected. Corresponding fastening units 132 of a different subtype are designed such that, in a fastened state with the fastening unit 132 having the detection area 162, no section of the corresponding fastening unit 132 of the other subtype that enables detection is arranged in the detection area 162. In particular, in such a fastened state with a fastening unit 132 of the other subtype, the sensor 156 of the fastening unit 132 with the detection area 162 is thus not triggered.

[0207] Advantageously, in this embodiment, this sensor 156 can distinguish between a fastened state of the fastening unit 132 assigned to it with a fastening unit 132 having an element 164 to be detected, on the one hand, and further states of the fastening unit 132 assigned to it, in particular a released state and / or a fastened state with a fastening unit 132 without a section enabling detection, on the other hand.

[0208] For example, a detection area 162 of at least one sensor 156 is formed in a mounting receptacle 136 of the mounting unit 132 assigned to it and advantageously formed at least in one end region, for example, at one end 166 of the mounting receptacle 136. The mounting receptacle 136 extends from a receiving opening 168 to the end region and end 166 of the mounting receptacle 136.

[0209] In particular, a fastening counterpart 138 of fastening units for modules whose fastened state is to be detected is longer than a fastening counterpart 138 of fastening units 132 for modules that are not intended to trigger the sensor 156. This is illustrated by way of example in Figures 5 and 6 for the fastening receptacle 136 of the handle-side fastening unit 132 of the device module 112 and a fastening counterpart 138 of a fastening unit 132 of an extension module 138, which is longer than a fastening counterpart 138 of a fastening unit 132 of the handle module 114.However, a fastening unit 132 of the application-side fastening unit 132 or a fastening receptacle 136 of a fastening unit 132 of another module and / or fastening counterparts 138 of fastening units of other modules can also be designed accordingly, so that the illustrations in Figures 5 and 6 are also representative of such configurations.

[0210] In some advantageous variants, at least one sensor 156 is a contact sensor. In particular, the contact sensor is arranged at least partially in its detection area 162.

[0211] In particular, an element 164 to be detected for the contact sensor is a contact section of the corresponding fastening unit 132, wherein in a fastened state of the fastening unit 132 assigned to the contact sensor with the corresponding fastening unit 132, the contact section protrudes into the detection area 162 and triggers the contact sensor.

[0212] In particular, corresponding fastening units 132 of a subtype are designed such that, in a fastened state with a fastening unit 132 to which a contact sensor is assigned, no section of the corresponding fastening unit 132 of this subtype protrudes into the detection area 162 of the contact sensor and thus the contact sensor is not triggered in such a fastened state.

[0213] In some advantageous variants, at least one sensor 156 of the detection device 152 is a non-contact sensor.

[0214] In particular, a non-contact sensor is a magnetic sensor, in particular a Hall sensor.

[0215] In particular, a corresponding fastening unit 132 of one subtype has a magnet as the element 164 to be detected. For example, a corresponding fastening unit 132 of another subtype does not include a magnet.

[0216] Thus, the magnetic sensor can distinguish between a fastened state of the fastening unit 132 assigned to it with a corresponding fastening unit 132 of one subtype with a magnet on the one hand and other states of the fastening unit 132 assigned to it, in particular a released state and a fastened state with a corresponding fastening unit 132 of the other subtype without a magnet.

[0217] Preferably, the device 100, in particular at least its device technology in the device module 112 and / or at least one functional unit, can be operated in at least two different operating modes.

[0218] Advantageously, the at least two operating modes comprise at least one continuous operating mode and / or at least one action operating mode. The at least one continuous operating mode and the at least one action operating mode are active operating modes in a switched-on state.

[0219] In addition, the device 100, in particular at least its device technology and / or at least one functional unit thereof, has at least one switched-off state.

[0220] Advantageously, the device 100, in particular at least its device technology and / or at least one functional unit, has at least one sleep mode in the switched-on state.

[0221] In particular, the device 100, in conjunction with the hot fluid generation unit, has at least one continuous operating mode and one active operating mode in a switched-on state, and, for example, a sleep mode in the switched-on state. In particular, the hot fluid generation unit releases a hot fluid in an active operating mode. In particular, in a sleep mode, at least the release of hot fluid is interrupted. However, for example, in a sleep mode, heating elements of the hot fluid generation unit are still at least partially active.

[0222] In particular, in a rest mode, no fluid is passed through a hot fluid generation unit designed as a continuous flow heater and released as hot fluid.

[0223] In particular, in a hot fluid generation unit having a boiler unit for heating a fluid, no hot fluid is dispensed in a rest mode, but, for example, hot fluid or at least a heated fluid is kept ready in the boiler unit.

[0224] In particular, in the continuous operation mode, it is provided that at least the functional unit, in particular the device 100, remains in the continuous operation mode after switching to the continuous operation mode until the continuous operation mode is actively ended by an actuation by a user.

[0225] In particular, a user can switch the device into continuous operation mode by operating a control element and end the continuous operation mode by operating the control element.

[0226] For example, after switching to the at least one continuous operation mode, the hot fluid generation unit continuously releases hot fluid until the continuous operation mode is ended by a user actuation.

[0227] In the at least one action operating mode, it is provided that at least the functional unit, for example, device 100, remains in an active mode after switching to the action mode, but only if a required action by a user occurs in a timely manner. In some variants, in order to remain in at least one action mode, a user action must occur at the latest after a predetermined time interval. In particular, the duration of the predetermined time interval is a few seconds, for example, between one second and ten seconds. In some variants, a continuous user action is required to remain in at least one action operating mode.

[0228] For example, in at least one action operating mode, the hot fluid generating unit releases hot fluid as long as the user performs the required action in a timely manner, and the release of the hot fluid ends when the required action is not performed, i.e. the user does not perform the required action within the predetermined time interval or ends the continuous action.

[0229] It is particularly advantageous if the device 100 switches between the at least two operating modes depending on a state detected by the detection device 152.

[0230] This is particularly advantageous if at least one functional unit of the device 100 is to be and / or is to be operated in different device configurations 105 in different operating modes.

[0231] For example, it is provided, particularly for safety-related reasons, that the hot fluid generation unit in a device configuration 105IV, which corresponds to a small handheld device, is operated only in an action operating mode.

[0232] In particular, advantageous variants provide for the detection device 152 to be configured to detect whether an extension module 118 is attached to the handle-side fastening unit 132 of the device module 112. In particular, such a variant provides for the hot fluid generation unit to be operated by default in at least one action mode, so that the hot fluid is only provided upon regular and timely action by the user. If, in such a variant, the detection device 152 detects that an extension module 118 is attached to the handle-side fastening unit 132 of the device module 112, the operating mode of at least the hot fluid generation unit is switched to a continuous operating mode, so that hot fluid is continuously released from the switching on until the continuous operating mode is actively terminated.

[0233] In some variants, the detection device 152 is at least configured to detect whether the handle module 114 is attached to the handle-side fastening unit 132 with the device module 112. In particular, in such variants, at least one action operating mode is switched to, at least for the hot fluid generation unit, provided the detection device 152 detects that the handle module 114 is attached to the handle-side fastening unit 132 with the device module 112.

[0234] In some advantageous variants, the detection device 152 is at least designed such that it can detect whether an application module 116 is attached to the application-side attachment unit 132 of the device module 112. In particular, in such variants, it is provided that at least the operating mode of the hot fluid generation unit is switched to at least one action operating mode when the application-side attachment unit 132 of the device module 112 is in a fastened state with a attachment unit 132 of an application module 116. It is particularly advantageous in such variants if the detection device 152 is further designed to detect whether an extension module 118 with its attachment unit 132 is attached to the handle-side attachment unit 132.Then it is provided that at least the operating mode of the hot fluid generation unit is switched to a continuous operating mode when the handle-side fastening unit 132 is in a fastened state with a fastening unit 132 of an extension module 118, even if the application module 116 with its fastening unit 132 is fastened to the application-side fastening unit 132, since then a device configuration corresponding to a long handheld device, for example the device configuration 1051, is formed and in this the hot fluid generation unit can be operated in a continuous operating mode.

[0235] The structure of a device 100 is described in more detail below in connection with, for example, illustrations in Figures 7 to 14. In some variants of this exemplary embodiment, the device 100 is constructed in a modular manner, for example from at least one device module 112 and / or a handle module 114 and / or at least one application module 116 and / or at least one extension module 118, in particular as explained above. In other variants of the exemplary embodiment, the device 100 is constructed at least partially as an integral device 100. Unless explicitly referred to one of these variants below, the corresponding description applies to the different variants of the device 100. Possible differences between the various variants of the exemplary embodiment are explained in more detail below.

[0236] The device 100 comprises in particular a device housing 212 and the device housing 212 defines a housing interior 214.

[0237] By way of example, a device housing 212 and a housing interior 214 are shown in variants in sections in Figures 7 and 8.

[0238] In particular, the device housing 212 is formed from several parts. For example, two shell parts are provided, which essentially define the housing interior 214. In particular, the housing parts are formed at least largely from a plastic material.

[0239] By way of example, Fig. 9 shows a housing part, for example a shell part, which at least co-defines the housing interior 214, for a variant in which a device module 112 and additional modules attachable to the device module, in particular a handle module 114 and an application module 116 and, for example, at least one extension module 118, are provided. The device housing 212 is a housing of the device module 112.

[0240] By way of example, for variants of a handle module 114, a part, in particular a shell part, which at least partly forms a handle module 114 is shown in Figures 10 and 11.

For example, a handle is also formed by the device housing 212. The device housing 212 is a housing of the at least partially integral device 100.

[0242] In particular, the device housing 212 has a front side 222 and a rear side 224, wherein the front side 222 and the rear side 224 are opposite sides of the device housing 212 with respect to a main direction 216.

[0243] In particular, an arrangement point 232 for an application unit 236 is formed on the front side 222, wherein an application unit 236 is at least arrangeable and / or arranged at the arrangement point 232.

[0244] In some variants of the device 100, the arrangement point 232 is a fastening unit 132, which is preferably at least partially designed as explained above. In these variants, the application unit 236 is a separate application module 116, which is preferably at least partially designed as explained above. The separately designed application unit 236 has a corresponding fastening unit 132, with which this application unit 236 can be fastened, in particular releasably, to the arrangement point 232 designed as a fastening unit 132. In some variants of the device 100, the application unit 236 is formed integrally with the device housing 212. In particular, at least a part of the application unit 236 is then arranged, in particular fixedly arranged, at the arrangement point 232 on at least one part of the device housing 212 that co-defines the housing interior 214.For example, these parts are joined together at the arrangement point 222. For example, in such variants, at least a part of the application unit 236 and at least one housing part that co-defines the housing interior 214 are at least partially formed in one piece.

[0245] In particular, the device housing 212 has a top side 242 and a bottom side 244, wherein the top side 242 and the bottom side 244 are opposite sides of the device housing 212 in a vertical direction 246 of the device housing 212.

[0246] The vertical direction 246 and the main direction 226 of the device housing 212 run at least approximately perpendicular to each other.

[0247] In particular, the device housing 112 has a particularly flat base 252 on the underside 244. In particular, the base 252 extends at least substantially in the main direction 226 and the transverse direction 256.

[0248] A transverse direction 256 runs at least approximately perpendicular to the main direction 226 and at least approximately perpendicular to the vertical direction 246 of the device housing 212. For example, the device housing 212 has two lateral sides which are opposite sides of the device housing 212 in the transverse direction 256.

[0249] In this description, the directions "front" and "back" are to be understood with respect to the main direction 226, the directions "top" and "bottom" are to be understood with respect to the vertical direction 246, and the directions "lateral" are to be understood with respect to the transverse direction 256. The device 100 comprises a handle unit 262. The handle unit 262 comprises at least one handle element 264, which forms a handle.

[0250] In some advantageous embodiments, the handle unit 262 is designed as a separate handle module 114. Figures 10 and 11 show exemplary variants of a handle unit 262 designed as a handle module 114.

[0251] In some advantageous embodiments, the handle unit 262 is formed at least partially, preferably at least largely, from the device housing 212, in particular from at least one housing part that co-defines the housing interior 214. Variants with a handle unit 262, which is in particular at least partially integrated into the device housing 212, are illustrated by way of example in Figures 12 and 13.

[0252] Unless explicitly stated below, the description of a handle unit 262 refers both to embodiments and variants thereof in which the handle unit 262 is a separate handle module and to other embodiments and variants thereof in which the handle unit 262 is at least partially integrated into the device housing 212.

[0253] The handle element 264 extends longitudinally between a front end 266 and a rear end 268, wherein the front end 266 is advantageously arranged in front of the rear end 268 with respect to the main direction 226.

[0254] The device housing 212 has an arrangement point 272 at which the handle unit 262 can be arranged and / or is arranged on at least a part of the device housing 212.

[0255] In embodiments in which the handle unit 262 is a separate handle module 114, a fastening unit 132 is formed at the arrangement location 272 for the handle unit 262. Furthermore, the handle module 114 forming the handle unit 262 has a fastening unit 132, which is preferably arranged at the front end 266 of the handle element 264. In particular, the fastening units 132 are at least partially formed as explained above.

[0256] In embodiments in which the handle unit 262 is at least partially integrated into the device housing 212, the handle element 264 or an arrangement element for the handle element preferably merges into a further element and / or a further section of the device housing 212 at the arrangement point 272, in particular in one piece, and / or the handle element 264 or the arrangement element and the further element and / or the further section of the device housing 212 are joined together, for example, at the arrangement point 272.

[0257] In particular, the location 272 is formed at the front end 266 of the handle member 264 or the location member.

[0258] For example, the locating element extends from the locating location to the front end 266 of the handle element 264.

[0259] In some advantageous embodiments, the handle element 264 has at least one free end 266, 268, which is in particular the rear end 268, as shown by way of example in variants in Figures 2, 7, 10 and 12.

[0260] In some advantageous embodiments, at least one further element of the handle unit 262 is arranged at the front end 266 of the handle element 264, and at least one further element of the handle unit 262 is arranged at the rear end 268 of the handle element 264, as shown by way of example in variants in Figures 3, 8, 11, and 13. Conveniently, the handle unit 262 comprises at least one support element 276, 278, preferably at least one front support element 276 and / or one rear support element 278.

[0261] Advantageously, the at least one support element 276, 278 is arranged at one of the longitudinal ends 266, 268 of the handle element 264 and in particular the front support element 276 is arranged at the front longitudinal end 266 and / or the rear support element 278 is arranged at the rear longitudinal end 268.

[0262] Conveniently, the device housing 212 comprises at least one support element 284, on which the at least one support element 276, 278, in particular the at least two support elements 276 and 278, are supported.

[0263] In variants in which the handle unit 262 is a separate handle module 114, the support element 284 comprises in particular a support surface 286, on which the at least one support element 276, 278 or the plurality of support elements 276 and 278 are supported in a fastened state.

[0264] In some variations, it is provided that the at least one support element 276, 278 is supported on the support element 284 directly adjacent to the support surface 286.

[0265] In advantageous variations, the handle unit 262 comprises a contact element 288, which is advantageously formed at least partially in one piece with at least one support element 276, 278, and in a fastened state, the contact element 288 rests against the support surface 286 of the support element 284. In particular, the support element 276 can thus advantageously be indirectly supported over a large area on the support element 284 via the contact element 288.

[0266] In particular, in some variants, the contact element 288 extends between the two support elements 276 and 278 and the contact element 288 is arranged with opposite longitudinal ends on one of the two support elements 276 and 278.

[0267] In variants with at least partially integrated handle unit 262, at least one support element 276, 278 and preferably the two support elements 276 and 278 are arranged to support each other on the support element 288, in particular formed on the support element 288.

[0268] For example, the two support elements 276 and 278 extend, in particular at least substantially in the vertical direction 246, from the handle element 264, so that the support element 284 and / or the contact element 288 is spaced from the handle element 264.

[0269] Advantageously, the handle unit 262 has a through-opening 292, wherein the handle element 264, in particular with a downwardly oriented side, partially delimits the through-opening 292.

[0270] For example, the front support element 276 limits the through-opening 292 at the front and the rear support element 278 limits the through-opening 292 at the rear.

[0271] Preferably, an element arranged opposite the handle element 264 in the vertical direction 246 delimits the access opening 292 at the bottom. For example, the oppositely arranged element is an element of the device housing 212. In some advantageous variants, the oppositely arranged element is an element of the handle unit 262, which extends, for example, between the two support elements 276 and 278. In particular, the oppositely arranged element is a support element 284 or a contact element 288, depending on the variant.

[0272] Advantageously, the through-opening 292 is formed continuously in the transverse direction 256, so that a user of the device 100 can reach through the through-opening 292 in this direction to grasp the handle formed by the grip element 264.

[0273] Thus, the device housing 212 has a handle region 296 in which, depending on the variant of an embodiment, a handle unit 262 is formed and / or can be arranged and at least fastened to the device housing 212.

[0274] Thus, in some variants of some embodiments, the grip element 264 and advantageously at least one support element 276, 278 and, for example, the support element 284 are formed in the grip region 296.

[0275] In some embodiments, the device housing 212 has a recess 298 in the handle region 296, into which the separate handle unit 262 attachable to the device housing 212 can be inserted.

[0276] Conveniently, the arrangement point 272 for the handle unit 262, which preferably comprises a fastening unit 132, is arranged at a front end of the recess 298.

[0277] The recess 298 is, for example, essentially bounded downwards by the support surface 286.

[0278] In particular, the grip region 296 is located above a longitudinal center plane 312 of the device housing 212 and behind a vertical center plane 314 of the device housing 212.

[0279] In particular, the longitudinal center plane 312 extends at least substantially in the main direction 226 and the transverse direction 256 and runs at least approximately perpendicular to the vertical direction 246. In particular, at least 40% of a total extent of the device housing 212 in the vertical direction 246 is located above and / or below the longitudinal center plane 312. In particular, the vertical center plane 314 extends at least substantially in the vertical direction 246 and in the transverse direction 256, and the vertical center plane 314 runs at least approximately perpendicular to the main direction 226. In particular, at least 40% of a total extent of the device housing 212 in the main direction 226 is located in front of and / or behind the vertical center plane 314.

[0280] Between the arrangement point 232 for the application unit 236 and the arrangement point 272 for the handle unit 262, the device housing 212 has an arrangement section 322.

[0281] By way of example, in Fig. 14 the arrangement section 322 is shown in an enlarged view for a variant in which the arrangement points 232, 272 for the application unit 236 and for the handle unit 262 are designed as fastening units 132.

[0282] A design of the arrangement section 322 as explained below is advantageously provided for variants in which at least one of the arrangement points 232, 272 is designed as a fastening unit 132 and / or in which at least the application unit 236 and / or the handle unit 262 are at least partially formed integrally with the device housing 212. Thus, the illustration in Fig. 14 is also representative of other variants, and advantageously, the designs explained in connection with Fig. 14 are at least partially also provided for other variants, for example those for which the illustrations in Figs. 12 and 13 are exemplary.

[0283] In particular, the arrangement location 272 for the handle unit 262 is arranged further up with respect to the vertical direction 246 than the arrangement location 232 for the application unit 236. Advantageously, the arrangement section 322 is oriented obliquely downwards in its forward extension towards the front side 222.

[0284] In particular, the arrangement section 322 extends at least substantially along a geometric arrangement axis 326. The arrangement axis 326 runs through the two arrangement locations 232 and 272.

[0285] In particular, an axial direction of the arrangement axis 326 is defined by an elongated extension of an arrangement element at the arrangement location 232, 272. For example, an arrangement element is a fastening counterpart 138 and / or a fastening receptacle 136 or an element at which a part of the application unit 236 or handle unit 262, on the one hand, and a part of the arrangement section 322, on the other hand, merge into one another and / or are joined to one another.

[0286] Conveniently, a central axis of an arrangement element runs on the arrangement axis 326 or at least approximately parallel to the arrangement axis 326, wherein the central axis is defined by an elongated extension of the arrangement element. If the central axis is offset from the arrangement axis 326, the offset between the two axes is preferably smaller than the elongated extension of the arrangement element, in particular smaller than half of this elongated extension.

[0287] Preferably, device electronics are arranged at least partially, in particular at least largely, in the arrangement section 322.

[0288] Conveniently, the arrangement section 322 comprises an outer wall segment 332 of the device housing 212. In particular, the outer wall segment 332 extends obliquely to the main direction 226 and obliquely to the vertical direction 246 between the two arrangement locations 232 and 272. For example, the outer wall segment 332 of the arrangement section 322 extends at least partially parallel to the arrangement axis 326 and / or at least partially obliquely, conveniently only slightly obliquely, to the arrangement axis 326.

[0289] In particular, the device housing 212 has an interaction side 342. Preferably, the interaction side 342 is formed on the arrangement section 322 and in particular on its wall segment 332.

[0290] On the interaction side 342, the device 100 has at least one operating element 246 of an operating device of the device 100 and / or at least one display element of a display device of the device 100.

[0291] In particular, at least one operating element 346 is designed to switch the device on and off. Conveniently, at least one operating element 346 is provided, the actuation of which is required as an action in at least one action operating mode. In particular, at least one operating element 346 is a button.

[0292] At least one state of the device 100 is displayed using at least one display element. For example, a display element indicates whether the device is switched on and / or off. In particular, a display element indicates at least one operating mode in which the device is operated.

[0293] Depending on the variant, at least one display element is a simple light source, in particular an LED. In some variants, at least one display element is designed for more complex display of information about the device's status, for example, a display.

[0294] In particular, the arrangement of the control elements and / or display elements for interaction between the user and the device on the angled interaction side 242 of the arrangement section 322 is advantageous, since these elements are thus conveniently accessible and / or visible to a user when using the device 100 in various orientations. The arrangement of the control elements 346 on the arrangement section 322, and in particular close to the arrangement point 272 for the handle unit 262, is advantageous, since these control elements 346 are thus easily accessible to the user holding the device 100 by the handle of the handle unit 262.

[0295] Conveniently, the device 100 comprises a water tank 352. The water tank 352 can be arranged in a water tank region 354 of the device housing 212 on the device housing 212 and can be detachably fastened to the device housing 212.

[0296] In particular, the water tank 352 has a storage space for storing a liquid.

[0297] Conveniently, the water tank 352 has a fluid connection. Using the fluid connection, the storage space of the water tank 352 can be connected in a fluid-conducting manner to a conduit device in the device housing 212. Conveniently, a hose is arranged in the storage space, one end of which leads to the fluid connection. A weight is arranged at another end of the hose, and at this end the hose opens into the storage space. Advantageously, even with different orientations of the device 100, the hose end opening into the storage space is arranged in a lower region of the storage space with respect to gravity. Thus, even when the liquid level in the storage space is low, this hose end is immersed in the liquid, and the liquid can be drained away via the hose.

[0298] In particular, the device housing 212 has a recess 356 in the water tank region 354, wherein the water tank 352 is received in the recess 356 for fastening.

[0299] In particular, a fastening mechanism for the water tank 352 is formed at least partially on the device housing 212 in the water tank region 354. For example, a fastening mechanism designed as a locking mechanism comprises locking members and locking receptacles. The locking receptacles and the locking members lock together for a releasable fastening of the water tank 352. In particular, at least some locking members are formed on the water tank 352 and corresponding locking receptacles are formed on the device housing 212 and / or at least some locking members are formed on the device housing 212 and corresponding locking receptacles are formed on the water tank 352.

Advantageously, the edge portion 358 initially extends from the rear side 224 of the device housing 212 essentially forward in the main direction 226 and then extends downward in the vertical direction 246 to the underside 244 of the device housing 212.

[0302] The device housing 212 includes a rear portion 364 which extends to the back 224.

[0303] In particular, the rear portion 364 is at least partially delimited upwards by the element delimiting the grip region 296, that is to say in particular by the contact element 388 or the support element 284, and at least partially delimited downwards by the edge portion 158 of the water tank region 354.

[0304] In particular, the rear portion 364 is at least partially a narrow portion relative to its extent in the vertical direction 246, since the handle region 296 is formed at least partially above the rear portion 364 and the water tank region 354 is formed below the rear portion 364. For example, a narrow extent of the rear portion 364 in the vertical direction 246 amounts to at most 20% of the total extent of the device housing 212 in the vertical direction 246.

[0305] In particular, the rear portion 364 extends forward from the rear side 224 along the handle region 296 and the water tank region 354 and to the front end of that region 296, 354 which extends further forward in the main direction 226.

[0306] For example, the handle region 296 extends further forward than the water tank region 354. In the area along the main direction 226 in which the handle region 296 still advantageously extends forward, but the water tank region 352 no longer does, the rear portion 364 advantageously widens downwards to the underside 244 of the device housing 212.

[0307] The device 100 includes a power supply unit 372. The power supply unit 372 is advantageously arranged at least substantially in the rear portion 364.

[0319] In particular, in an active operating mode, the hot fluid generation unit 378 delivers hot fluid to the application unit 236 via the conduit device. In particular, no hot fluid is supplied to the application unit 236, at least in a sleep mode and / or a switched-off state.

[0320] Conveniently, a pump 382 is arranged in the conduit device. In particular, the pump 382 is arranged between the water tank region 354 and the hot fluid generation unit 378 with respect to the main direction 226. In particular, the pump 382 is arranged in the rear section 364 and there preferably in the area that widens to the underside 244.

[0329] For example, the container 422 has six outer wall sections 4281 to 428VI.

[0330] To the extent that the wall sections 428 are at least substantially identical, the multiple wall sections 428 are described jointly, and in particular, reference to a wall section 428 is to be understood such that at least one of the multiple wall sections 428, preferably at least some, for example all, of the multiple wall sections 428 have the described feature. In particular, if, in describing a wall section and / or an element / feature of a wall section, reference is to be made to at least one specific wall section in particular, a Roman numeral designating this specific wall section is appended to the corresponding reference symbol.The corresponding Roman numeral is to be understood merely as the name of the specific wall section and the Roman numeral does not imply any further information, in particular the Roman numerals do not imply any ranking of the wall sections 428 and / or they do not imply any information about the total number of wall sections.

[0331] In particular, each of the wall sections 428 has a respective inner wall surface 432 and a respective outer wall surface 434. The inner wall surface 432 and the outer wall surface 434 of a wall section 428 are opposite wall surfaces of the wall section 428 in a thickness direction 438 of the wall section 428.

[0332] With the inner wall surface 432, the wall section 428 defines the interior space 424, and the outer wall surface 434 faces the surroundings of the container 422, and in particular, the surroundings of the cartridge 410. In particular, the interior space 424 is enclosed by the inner wall surfaces 432 of all wall sections 428.

[0333] In particular, each of the wall sections 428 extends substantially in an extension surface. The extension surface runs, at least locally, at least approximately perpendicular to the thickness direction 438 of the wall section 428.

[0334] In preferred variants, at least some of the wall sections 428 are planar wall sections, and their extension surface is an extension plane spanned by two extension directions 442, 444 that are at least approximately perpendicular to one another. In a planar wall section 428, its thickness direction 438 is oriented in the same direction at least over a large part of the extension of the planar wall section 428.

[0335] In some variants, at least one wall section 428 is curved. In a curved wall section 428, its extension surface is also correspondingly curved, and the orientation of the thickness direction 438 of the curved wall section 428 changes along the extent of the curvature.

[0336] For example, a respective wall section 428 extends in a longitudinal extension direction 442 and in a transverse extension direction 444, wherein the longitudinal extension direction 442 and the transverse extension direction 444 span the geometric extension area.

[0337] A respective wall section 428 extends in its extension area to at least one end region 452, 454 and in particular it extends between several end regions 452, 454.

[0338] For example, a wall section 428 extends in its longitudinal direction 442 between two opposite longitudinal end regions 452 and / or a wall section 428 extends in its transverse direction 444 between two opposite transverse end regions 454.

[0339] In particular, an extension of a wall section 428 in an extension direction 442, 444, for example in its longitudinal extension direction 442 and / or in its transverse extension direction 444, is greater, preferably substantially greater, than its thickness measured in the thickness direction 438.

[0340] In particular, at most 30% of a total extension of a wall section 428 in its extension direction 442, 444, for example in its longitudinal extension direction 442 and / or in its transverse extension direction 444, is located in an end region 452, 454.

[0341] In particular, two wall sections 428 are arranged adjacent to each other with respective end regions 452, 454 in an edge region 462. In particular, the end regions 452, 454 of three wall sections 428 and thus also the edge regions 462 between these wall sections 428 meet in a respective corner region 466.

[0342] For example, at least some wall sections are rounded in their end regions 452, 454 and accordingly the container 422 has at least some rounded edge regions 462 and / or corner regions 466, as shown by way of example in Fig. 15.

[0343] In particular, the container 422 expands in an expansion plane 468. The expansion plane 468 is spanned by two expansion directions 472 and 474, which, for example, are at least approximately perpendicular to each other.

[0344] In particular, the container 422 has a smaller extension in a height direction 476 than in the two extension directions 472 and 474. In particular, the height direction 476 runs at least approximately perpendicular to the extension plane 468.

[0345] A height of the container 422 is measured in the height direction 476. For example, the height of the container 422 is at most 70%, in particular at most 50%, of a smallest dimension of the container 422 in the dimension directions 472, 474.

[0346] In particular, two wall sections 428, for example, a wall section 4281 and a wall section 428II, are spaced apart from one another in the height direction 476 and are advantageously arranged opposite one another in the height direction 476. These two wall sections 4281,11 preferably extend at least approximately parallel to the geometric extension plane 468. In particular, the extension directions 4421,11 of these two wall sections 4281,11, which are spaced apart from one another in the height direction 476, run substantially parallel to the geometric extension plane 468.

[0347] In particular, the two wall sections 4281 and 428II, which are spaced apart from each other in the height direction 476, have substantially the same shape in their extension surfaces and thus define, for example, a base area of ​​the container 422.

[0348] In particular, the wall sections 4281,11, which are spaced apart from one another in the height direction 476, are substantially rectangular, so that the base area of ​​the container 422 is also substantially rectangular, wherein the corners are preferably rounded, as shown by way of example in Fig. 15.

[0349] In particular, at least one wall section 428 extends between the two wall sections 4281,11, which are spaced apart from each other in the height direction 476, and is arranged in respective edge regions 462 on the two wall sections 4281,11.

[0350] In particular, the container 422 is substantially cylindrical in shape, with a wall section 428 extending in each of the opposite base surfaces of the cylindrical shape and at least one wall section 428 extending in a lateral surface of the cylindrical shape.

[0351] For example, lateral wall sections 428, here wall sections 428III to 428VI, extend in one of their extension directions 442, 444 in the height direction 476 between the two wall sections 428I,I1, which are spaced apart from one another in the height direction 476, and in their other extension direction 442, 444 between two other lateral wall sections 428III,IV,V,VI. For example, in the two extension directions 472, 474 of the container 422, two wall sections are arranged opposite one another. For example, wall sections 428III and 428V are arranged opposite one another in the extension direction 472, and wall sections 428IV and 428VI are arranged opposite one another in the extension direction 474.

[0352] In particular, the container 422 is formed from at least two different container parts 482, 484. In particular, the respective container parts 482, 484 are each formed as a single piece.

[0353] At least some of the container parts 482, 484, in particular all of the container parts 482, 484, each comprise at least one wall section 428.

[0354] Advantageously, one of the container parts, here the container part 484, is formed essentially from a wall section 428 and another container part, here the container part 482, comprises the remaining wall sections 428.

[0355] In particular, one container part 484, which is essentially formed from a wall section 428, is designed as a lid for the other container part 482. In particular, one of the wall sections spaced apart in the vertical direction 476, here the wall section 428II, essentially forms the one, in particular lid-like, container part 484.

[0356] Wall sections 428, which are formed by a same container part 482, 484 and are arranged next to one another in an edge region 462, are preferably formed onto one another in their edge region 462.

[0357] Wall sections 428, which are formed into different container parts 482, 484 and are arranged adjacent to one another in an edge region 462, are preferably positively connected to one another in their edge region 462, at least in an assembled state of the container 422. For this purpose, the two wall sections 428 advantageously have interlocking form-locking elements 492, 494. For example, one of the two form-locking elements 492, 494 has a groove, and the other of the two form-locking elements 492, 494 has a projection engaging in the groove.

[0358] The container 422 has an inlet 512 that opens into the interior space 424 at an inlet opening 514. The container 422 has an outlet 516 that opens into the interior space 424 at an outlet opening 518.

[0359] In particular, the inlet opening 514 is formed in one container part 482, 484 and the outlet opening 518 is formed in another container part 482, 484.

[0360] The inlet opening 514 and the outlet opening 518 are fluidically connected to each other in the interior space 424 at least along a connection 526. Thus, a fluid flowing through the inlet opening 514 into the interior space 424 can reach the outlet opening 518 along the connection 526.

[0361] In particular, the connection 526 runs at least along a geometric connecting line 528. In particular, the connecting line 528 runs straight and along the shortest distance between the inlet opening 514 and the outlet opening 518. For example, the connecting line 528 is the straight line that runs through a center point of the inlet opening 514 and a center point of the outlet opening 518.

[0362] Advantageously, the inlet opening 514 and the outlet opening 518 are arranged such that the connection 526 between the two openings 514 and 518 is optimized in length.

[0363] In particular, optimizing the length of the connection 526, and in particular optimizing the length of the connecting line 528, means that it is designed to be as long as possible, taking into account, for example, practical and / or technical conditions. For example, an opening 514, 518 cannot be formed arbitrarily close to an edge of one of the container parts 482, 484; rather, a sufficiently large edge section must be present to ensure the stability of the container part 482, 484.

[0364] In particular, the inlet opening 514 and the outlet opening 518 are arranged such that the shortest connection 526 between the two openings 514, 518 is the longest possible.

[0365] For length optimization, it is preferably provided that the inlet opening 514 and the outlet opening 518 are formed in wall sections 428 that are arranged opposite one another in a direction. In particular, the inlet opening 514 is formed in the wall section 428II, and the wall section 4281, in which the outlet opening 518 is formed, is arranged opposite this wall section 428II in the height direction 476.

[0366] In particular, the inlet opening 514 is formed in an end region 452, 454 of the wall section 428 in which the inlet opening 514 is formed. In particular, the outlet opening 518 is formed in an end region 452, 454 of the wall section 428 in which the outlet opening 518 is formed.

[0367] In particular, the two end regions 452, 454, in each of which an opening from the inlet opening 514 and the outlet opening 518 is formed, are located opposite each other in at least one direction.

[0368] In particular, the longitudinal extension direction 442II of the wall section 428II, in which the inlet opening 514 is formed, and the longitudinal extension direction 442I of the wall section 428I, in which the outlet opening 518 is formed, run at least approximately parallel to one another and / or the transverse extension direction 444II of the wall section 428II, in which the inlet opening 514 is formed, and the transverse extension direction 444I of the wall section 428I, in which the outlet opening 518 is formed, run at least approximately parallel to one another.

[0369] In particular, the inlet opening 514 and the outlet opening 518 are formed in regions of their wall sections 428, wherein these regions are opposite regions in at least one extension direction 442, 444, preferably in both extension directions 442, 444, of their wall sections 448.

[0370] In particular, the region in which the inlet opening 514 is formed in its wall section and the region in which the outlet opening 518 is formed in its wall section 428 are located opposite to each other with respect to at least one of the extension directions 472, 474 of the container 422, preferably in both extension directions 472, 474 of the container 422.

[0371] In particular, the projection of the inlet opening 514 and the projection of the outlet opening 518 onto at least one geometric projection plane are located opposite to each other in at least one direction.

[0372] In particular, the projection of the inlet opening 514 and the projection of the outlet opening 518 are located opposite to one another in at least one direction in a projection plane 534 running at least substantially perpendicular to the height direction 476, in particular in at least one extension direction 472, 474 of the container 422, preferably in both extension directions 472, 474 of the container 422, and / or in at least one extension direction 442, 444 of a wall section 428 in which the inlet opening 514 or the outlet opening 518 is formed, preferably in at least some of these extension directions 442, 444 of the wall sections 428 in which the inlet opening 514 or the outlet opening 518 is formed, opposite to one another.

[0373] In particular, the projection of the inlet opening 514 and the projection of the outlet opening 518 are opposite to each other in a projection plane 536 that runs parallel to the height direction 476, in a direction that runs perpendicular to the height direction 476 and in the projection plane 536.

[0374] In particular, further projection planes in which the projections of the inlet opening 514 and the outlet opening 518 are located opposite to each other in at least one direction are projection planes which run at least approximately perpendicular to at least one extension direction 472, 474 of the container 422 and / or projection planes which run at least approximately perpendicular to at least one extension direction 442, 444 of a wall section 428 in which the inlet opening 514 or the outlet opening 518 is formed.

[0375] In particular, the inlet opening 514 is formed in at least one edge region 462, wherein this edge region 462 is formed by the wall section 428 in which the inlet opening 514 is formed, and at least one further wall section 428. Preferably, the inlet opening 514 is formed in a corner region 466 of the container 422, wherein this corner region 466 is formed by the wall section in which the inlet opening 514 is formed and at least two further wall sections 428. In particular, in this exemplary embodiment, the corner region 466 and thus also edge regions 462 in which the inlet opening 514 is formed extend through one wall section 428II or at least transversely to the height direction 476, and further wall sections 428IV and 428V, one of whose extension directions 442, 444 runs at least substantially parallel to the height direction 476.In particular, the outlet opening 518 is formed in at least one edge region 462 of the container 422, wherein this edge region 462 is formed by the wall section 428 in which the outlet opening 518 is formed, and at least one further wall section 428. Preferably, the outlet opening 518 is formed in a corner region 466 of the container 422, wherein this corner region is formed by the wall section 428 in which the outlet opening 518 is formed, and at least two further wall sections 428. In particular, in this embodiment, the corner region 466 and thus also edge regions 462, in which the outlet opening 518 is formed, are formed by a wall section 4281, which extends at least transversely to the height direction 476, and further wall sections 428III and 428VI, one of whose extension directions 442, 444 run at least substantially parallel to the height direction 476.

[0376] Advantageously, the wall sections 428 which form the edge region 462 and in particular the corner region 466 in which the inlet opening 514 is formed are different wall sections than those wall sections 428 which form the edge region 462 and in particular the corner region 466 in which the outlet opening 518 is formed.

[0377] In particular, the edge region 462 and in particular the corner region 466, in which the inlet opening 514 is formed, on the one hand, and the edge region 462 and in particular the corner region 466, in which the outlet opening 518 is formed, on the other hand, are oppositely located regions 462, 466 in at least the height direction 476 and / or in at least one of the two extension directions 472, 474 of the container 422, preferably in both of the two extension directions 472, 474. Advantageously, these edge regions 462 and / or corner regions 466 are oppositely located in several of these directions 476, 472, 474.

[0378] In particular, the inlet opening 514 and the outlet opening 518 are formed in regions of the interior space 424, in particular in edge regions 462 and / or corner regions 466, which are located opposite one another along a spatial diagonal of the interior space 424.

[0379] In particular, the spatial diagonal runs obliquely to at least the height direction 476 and / or obliquely to the two extension directions 472, 474.

[0380] In particular, a connection 526 between the inlet opening 514 and the outlet opening 518 is thus designed to be length-optimized, since the two openings 514, 518 are formed in opposite regions, in particular opposite edge regions 462 and / or corner regions 466, of the container 422.

[0381] Advantageously, the connection 526 between the inlet opening 514 and the outlet opening 518 is designed to be barrier-free, at least in an unfilled state of the cartridge 410. Advantageously, the direct connection 526, which runs in particular along the connecting line 528 between the inlet opening 514 and the outlet opening 518, is designed to be barrier-free, at least in the unfilled state.

[0382] Advantageously, a connecting space region 542 is designed to be barrier-free, at least in the unfilled state. The connecting space region 542 extends in a connecting direction 544 from the inlet opening 514 along the connection 526 to the outlet opening 518 and extends transversely to the connecting direction 544.

[0383] In particular, the connecting space region 542 extends along the direct connecting line 528 from the inlet opening 514 to the outlet opening 518.

[0384] Advantageously, the connecting space region 542 extends transversely to the connecting direction 544 at least with an extent which at least substantially corresponds to the extent of the inlet opening 514 and / or the extent of the outlet opening 518 and in particular corresponds to at least twice this extent.

[0385] It is particularly advantageous if the connecting space region 542 extends at least up to the inner wall surface 432 of the wall section 428 in which the inlet opening 514 is formed, and up to the inner wall surface 432 of the wall section 428 in which the outlet opening 518 is formed, and / or preferably up to inner wall surfaces 432 of at least some other wall sections 428, in particular up to the inner wall surfaces 432 of all wall sections 428.

[0386] In particular, the entire interior space 424 is designed to be barrier-free, at least in the unfilled state.

[0387] In particular, an area of ​​the interior 424 is designed to be barrier-free if no container part and / or no other part of the cartridge 410 and / or no other part protrudes into it. In particular, a barrier-free area is free of any parts.

[0388] In particular, the barrier-free connection 526 and the barrier-free connection space region 542 are advantageous because a large amount of fluid modification material 414 can be filled into the barrier-free region, in particular into the entire barrier-free interior space 424, and in the filled state, a liquid flowing from the inlet opening 514 to the outlet opening 518 can easily flow around the filled fluid modification material 414, but otherwise the flow of the liquid is not hindered by the barrier-free nature of the connection 526.

[0389] By arranging the inlet opening 514 and the outlet opening 518 such that the length of the connection 526 between the two openings 514 and 518 is optimized, the fluid flowing through the longest possible connection 526 allows the fluid to flow around as much of the fluid modification material 414 as possible. Advantageously, the fluid modification material 414 is a granular medium.

[0390] In particular, this enables favorable filling of the interior space 424 and the granular medium offers a large surface area for reaction with the liquid flowing through the interior space 424.

[0391] In particular, the fluid modification material 414 is designed to treat the liquid, for example to decalcify water.

[0392] Advantageously, a sieve 554 is arranged in the inlet opening 514. In particular, a sieve 558 is arranged in the outlet opening 518. In particular, the sieve 554 in the inlet opening 514 and / or the sieve 558 in the outlet opening 518 is designed such that it at least largely prevents the escape of the particularly granular fluid modification material 414 from the interior space 424 through the opening 514, 518. In particular, at least the sieve 554, 558 in the inlet opening 514 and / or in the outlet opening 518 is designed such that the liquid flowing through it can pass through this sieve 554, 558 as unhindered as possible. For example, at least the sieve 554 in the inlet opening 514 is designed such that any foreign particles that may be present in the incoming liquid are stopped by the sieve 554 and thus at least in reduced numbers or, advantageously, at least substantially not at all, reach the interior space 424.

[0393] In particular, the inlet 512 comprises an inlet nozzle 564. The inlet nozzle 564 comprises a flow space for the liquid leading to the inlet opening 514, wherein the flow space is circumferentially surrounded by a nozzle wall. Advantageously, the inlet nozzle 564, in particular its flow space and / or its nozzle wall, extends between the inlet opening 514 and one end of the inlet nozzle 564 transversely, in particular at least approximately perpendicularly, to the extension directions 424, 444 of the wall section 428 in which the inlet opening 514 is formed, and / or in particular at least substantially parallel to the height direction 476.

[0394] In particular, the outlet 516 comprises an outlet nozzle 568. The outlet nozzle 568 comprises a flow space for the liquid, wherein the flow space leads to the outlet opening 518 and is circumferentially surrounded by a nozzle wall of the outlet nozzle 568. Conveniently, the outlet nozzle 568, in particular its flow space and / or its nozzle wall, extends from the outlet opening 518 to one end of the outlet nozzle 568 transversely, in particular at least approximately perpendicularly, to the extension directions 442, 444 of the wall section 428 in which the outlet opening 518 is formed, and / or substantially parallel to the height direction 476.

[0395] Advantageously, the cartridge 410 is arranged in the housing interior 214 of the device housing 212 such that the height direction 476 of the container 422 runs at least substantially parallel to the main direction 226.

[0396] Conveniently, the wall section 428 in which the inlet opening 514 is formed faces the water tank region 354. In particular, the inlet nozzle 564 extends toward the water tank region 354.

[0397] Conveniently, the wall section 428 in which the outlet opening 518 is formed faces forward relative to the main direction 226 and, for example, faces the hot fluid generating unit 378 and / or the pump 382. In particular, the outlet nozzle 568 extends forward in the main direction 226, for example, toward the hot fluid generating unit 378 and / or toward the pump 382.

[0398] In particular, the cartridge 410 can be arranged in a space-saving manner adjacent to the water tank region 354 and in particular between the water tank region 354 of the device housing 212 on the one hand and the hot fluid generation unit 378 and / or the pump 382 on the other hand, since the container 422 has its smallest extension in the vertical direction 476. Nevertheless, it is possible for the liquid flowing through the cartridge 410 to flow around as much of the fluid modification material 414 as possible, since the connection 526 between the inlet opening 514 and the outlet opening 518 is designed to be length-optimized.

[0399] Preferably, the cartridge 410 is arranged in the device housing 212 such that the inlet 512 with the inlet opening 514 is arranged above the outlet 516 with the outlet opening 518 with respect to the vertical direction 246 of the device housing 212.

[0400] Advantageously, the inlet 512 is arranged in an uppermost region of the container 422, relative to the vertical direction 246 of the device housing 212, and in particular in an uppermost region of the cartridge 410. Advantageously, the outlet 516 is arranged in a lowermost region of the container 422, relative to the vertical direction 246 of the device housing 212, and in particular in a lowermost region of the cartridge 410.

[0401] In particular, the water tank 352 is fluid-conductingly connected to the inlet 512 of the cartridge 410 via at least one line section of the line device. Conveniently, the water tank 352, when attached to the device housing 212, is fluid-conductingly connected to the inlet 512 of the cartridge 410 via the at least one line section.

[0402] The outlet 516 is advantageously fluidically connected to at least one line section of the line device and, in particular, fluidically connected via the line device to the hot fluid generation unit 378 and / or to the pump 382.

[0403] Since the inlet 512 is advantageously arranged above the outlet 516, the flow of the liquid through the cartridge 410 is at least not impeded by gravity in at least most orientations of the device 100 during use of the device 100, and advantageously is at least assisted by gravity, since the inlet opening 514 is also arranged above the outlet opening 518 with respect to the direction of gravity. Advantageously, this arrangement of the inlet opening 514 above the outlet opening 518 is also present in at least most possible device configurations 105 of the device 100.
