[0007] The object underlying the invention is to improve a hot fluid device and an attachment for a hot fluid device.

[0008] In embodiments of the invention, the underlying object is achieved in that the hot fluid device comprises an application unit which is at least partially flexible in shape.

[0009] In embodiments of the invention, the underlying object is achieved by an attachment for a hot fluid device, wherein the attachment comprises an application unit which is at least partially flexible in shape.

[0010] In particular, an advantage of the solution according to the invention is that, since the application unit is designed to be flexible in its shape at least in sections, the application unit can adapt its shape to an external environment and thus advantageously improves the (direct and / or indirect) application of hot fluid.

[0011] In particular, during an application, the application unit is applied to an object, for example, an article and / or a surface. The object, in particular the article, often has a curved surface and / or is a surface that is curved at least in sections. Advantageously, the application unit, which is designed to be flexible in shape at least in sections, allows it to at least partially adapt to the shape, in particular to a curved surface, of the object during use, in particular during the (direct and / or indirect) application of hot fluid.

[0012] In particular, the application unit comprises an application region.

[0013] In particular, the application region is designed for at least one intended application of the hot fluid device and / or the attachment for a hot fluid device.

[0014] In particular, hot fluid, which is supplied in particular to the application unit, is applied directly and / or indirectly in the area of ​​the application region.

[0015] In particular, the hot fluid is applied at least partially to the object and / or to an application element in the application region.

[0016] Advantageously, the application element is an element designed for at least one function and / or application of the hot fluid device and / or the attachment for a hot fluid device, wherein the functionality of the application element is advantageously at least improved and / or enabled by the application of hot fluid. In particular, the application element is designed for, for example, the indirect application of the hot fluid when applied to an object.

[0017] In particular, the application element is at least partially fluid-permeable.

[0018] In particular, an application element can be at least fastened to at least one part which at least co-forms the application region.

[0019] It is particularly advantageous if the application unit is designed to be flexible in shape, at least in sections, such that the application region of the application unit is designed to be flexible in shape, at least in sections.

[0020] In particular, the application region can be better applied to an object which has a curved surface in particular due to its at least partially flexible design.

[0021] In particular, at least the application region extends in two directions of extension, wherein the two directions of extension run at least transversely to each other and in particular at least approximately perpendicular to each other. Advantageously, the application unit extends in both directions of extension.

[0022] In particular, the application region has a normal direction.

[0023] In particular, the normal direction of the application region runs at least approximately perpendicular to a areal extent of the application region. For example, the normal direction of the application region runs at least approximately perpendicular to a geometric surface spanned by the two extension directions of the application region.

[0024] In particular, at least one of the following is provided: - that the application unit, in particular at least the application region, is designed to be flexible in shape at least in sections along at least one direction of extension; and / or

[0025] - that the application unit, in particular at least the application region, is designed to be flexible in shape at least in sections in at least one direction, in particular is designed to be flexible in shape at least in sections in at least one normal direction of the application region.

[0026] Advantageously, the application unit can thus assume different shapes, wherein the different shapes of the application unit are different at least in sections, at least in the area of ​​the application region, at least along at least one direction of extension.

[0027] Advantageously, the different shapes that the application unit can take, in particular at least in the area of ​​the application region, are different at least in sections with regard to their design in one direction, in particular with regard to their design in the normal direction.

[0028] For example, the application unit can assume a shape that corresponds, in particular, to a basic position of the application unit, in which an orientation of a respective extension direction along the extension of the application unit and / or the application region is at least substantially constant in this corresponding extension direction. In particular, the geometric surface spanned by the two extension directions is a plane. In particular, the normal direction along the extension of the application region is at least substantially constant in the two extension directions.Conveniently, the application unit can assume at least one shape, i.e., precisely one shape or preferably multiple shapes, wherein, in the at least one shape, an orientation of at least one of the extension directions along the extension of the application unit and / or the application region varies at least in sections in this at least one extension direction. In particular, the surface spanned by the two extension directions is a surface that is curved at least in sections. In particular, an orientation of the normal direction along the extension of the application region varies in at least one extension direction.

[0029] In particular, it is advantageous if the shapes that the application unit, and in particular at least the application region, can assume differ at least partially in the normal direction, since in applications, the application region contacts the object to which the hot fluid is directly and / or indirectly applied at least substantially in the normal direction. Thus, a curved surface of the object, particularly in the normal direction, affects the application region and, for example, the application unit, and shape flexibility in at least this direction is particularly advantageous.

[0030] It is particularly advantageous if the application unit has different positions, i.e., in particular, at least two and preferably more than two positions. In particular, the at least partial shape flexibility of the application unit is provided by the different positions.

[0031] In particular, at least two parts of the application unit have different relative positions to one another in at least two different positions of the application unit. Advantageously, at least two parts of the application unit, which at least co-form the application region, have different relative positions to one another in at least two different positions of the application unit.

[0032] In particular, in at least two different relative positions of at least two parts, these at least two parts are positioned at least in different relative positions relative to each other and / or these at least two parts are at least differently aligned relative to each other.

[0033] In particular, the different relative positions of at least two parts of the application unit relative to each other in different positions of the application unit advantageously enable the shape flexibility of the application unit.

[0034] In some advantageous embodiments, at least some of the plurality of positions of the application unit, in particular at least some different relative positions of at least two parts of the application unit, are discrete different positions to one another.

[0035] In advantageous embodiments, at least two parts of the application unit can be continuously moved into different relative positions to one another, at least in a continuity spectrum.

[0036] Advantageously, at least two parts of the application unit are continuously movable and positionable relative to one another between at least two different relative positions as a continuity spectrum. Advantageously, at least two parts of the application unit are continuously alignable relative to one another between at least two relative orientations as a continuity spectrum.

[0037] In particular, at least one part of the application unit is positioned differently by at least 0.5 cm, in particular by at least 1 cm, preferably by at least 3 cm, in at least one form that can be occupied by the application unit relative to another form that can be occupied by the application unit. In particular, at least one part of the application unit is positioned differently by at least 0.5 cm, in particular by at least 1 cm, preferably by at least 3 cm, in at least two positions of the application unit within the application unit.

[0038] Advantageously, at least one relative position between at least two parts of the application unit in at least two different forms that can be taken up by the application unit, for example in at least two positions of the application unit, differs by at least 0.5 cm, in particular by at least 1 cm, preferably by at least 3 cm.

[0039] In advantageous embodiments, at least a part of the application unit is oriented differently by at least 10°, for example by at least 25°, preferably by at least 40° in at least one form that can be occupied by the application unit than in at least one other form that can be occupied by the application unit. In particular, at least a part of the application unit is oriented differently in at least two different positions of the application unit, wherein the different orientations of this part of the application unit in the at least two positions differ by an angle, wherein this angle is advantageously at least 10°, preferably at least 30°, in particular at least 40°.

[0040] For example, at least one relative orientation of at least two parts of the application unit differs in at least two different forms that can be assumed by the application unit, in particular in at least two different positions of the application unit, at least by an angle, wherein this angle is advantageously at least 10°, preferably at least 25°, for example at least 40°.

[0041] In particular, the application unit has a home position. In particular, the difference between at least one different position of at least one part of the application unit and / or the difference between at least one different orientation of at least one part of the application unit in at least one of two different positions refers to the difference relative to the position and / or orientation in the home position of the application unit.

[0042] In particular, in the basic position of the application unit, the application region is at least largely flat. In particular, the different position and / or different orientation of at least a part of the application unit in at least one of at least two different positions is related to a different position and / or a different orientation relative to the at least largely flat shape of the application region in the basic position.

[0043] In advantageous embodiments, the application unit is biased into a shape, in particular into a position.

[0044] Conveniently, the application unit is loaded into its basic position.

[0045] For example, the application unit is spring-loaded into one shape, in particular into one position.

[0046] Advantageously, the application unit, in particular at least the application region, assumes a shape determined by the application, in particular a shape corresponding to the basic position, and can nevertheless assume other shapes contrary to the application due to the at least partially flexible design. For example, handling by a user is more pleasant as a result, since the application unit, in particular at least the application region, is held in a fixed shape without external influence by the application. In some preferred embodiments, the application unit comprises a plurality of segments, i.e. in particular at least two segments and preferably more than two segments. In particular, at least some of the plurality of segments at least co-form the application region.

[0047] Preferably, at least two segments are mounted so as to be at least partially movable relative to one another.

[0048] In particular, at least two segments are mounted so as to be movable relative to each other at least within a permissible range of movement.

[0049] In particularly advantageous embodiments, at least two segments of the application unit are mounted so as to be pivotable relative to one another about a pivot axis, at least partially, in particular at least within a permissible pivoting range.

[0053] - that at least one stop is provided, in particular for the pivoting device, which limits a permissible pivoting range between at least two segments that can be pivoted relative to one another. Advantageously, the at least two segments, which are mounted so as to be movable, in particular pivotable, relative to one another, advantageously enable a flexible application unit that can also be designed to be structurally stable and / or simple.

[0054] In particular, two stops are provided in at least one pivoting device, wherein the two stops at opposite ends limit the permissible pivoting range of this pivoting device for at least two segments.

[0055] In particular, at least one pivot axis of at least two segments pivotable relative to one another runs at least approximately parallel to an extension direction of the application unit and / or the application region.

[0056] In particular, at least one pivot axis of at least two segments pivotable relative to one another runs transversely and in particular at least approximately perpendicularly to the normal direction of the application region.

[0057] Advantageously, at least two pivot axes of at least two segments of the application unit that can be pivoted relative to one another run at least approximately parallel to one another.

[0058] In some advantageous embodiments, a pivoting device for at least two segments that can be pivoted relative to one another has a guide section. At least one of the two segments that can be pivoted relative to one another is advantageously mounted on the guide section in a guided manner, at least within the permissible pivoting range. For example, the guide section is formed by one of the at least two segments that can be pivoted relative to one another. Preferably, if there are at least two segments that can be pivoted relative to one another, their pivoting device has a sliding section. In particular, the sliding section is formed by at least one of the two segments that can be pivoted relative to one another. Advantageously, the sliding section is movably mounted between two stops of the pivoting device. Advantageously, the sliding section is mounted in a guided manner on the guide section of this pivoting device.

[0059] In some preferred embodiments, at least one segment of the application unit is at least largely rigid. Advantageously, at least some, preferably at least most, of several segments of the application unit are each at least largely rigid.

[0060] For example, a segment that is at least largely rigid comprises at least one rigid segment body.

[0061] Advantageously, a stable and yet at least partially flexible application unit can be formed with at least largely rigid segments.

[0062] Preferably, at least two segments of the application unit are subjected to relative pressure. In particular, at least two segments of the application unit are subjected to a relative position corresponding to the basic position of the application unit. For example, this makes handling more comfortable for a user, since at least the two segments subjected to relative pressure are fixed in a relative position defined by the pressure without external influence.

[0063] In particularly advantageous embodiments, at least one of the following is provided: - that the application region of the application unit is formed adjacent to an application environment; and / or

[0072] Advantageously, a hot fluid can be supplied into the cavity formed as an outlet area and from there, for example, to the application region of an application. In particular, hot fluid that has been supplied to the cavity formed as an outlet area exits the application unit from the outlet area and, for example, into the application environment.

[0073] Advantageously, the cavity, which is provided and designed in particular as an outlet space region, has a plurality of spatial regions, wherein, for example, at least some of the plurality of spatial regions are contiguous spatial regions and / or in particular at least some of the plurality of spatial regions are separate spatial regions.

[0074] Preferably, at least one of the following is provided:

[0075] - that at least two spatial areas of the cavity, which is designed in particular as an exit space area, can assume different relative positions to one another due to the flexible design; and / or

[0077] - that in at least some of several segments of the application unit at least one spatial region of the cavity, which is designed in particular as an outlet space region, is formed.

[0078] Advantageously, this improves the distribution of the hot fluid to provide the hot fluid for an application, for example for a large-area application.

[0079] Advantageously, a hot fluid guide is provided for guiding a hot fluid.

[0080] In particular, at least one of the following is provided for:

[0081] - that the hot fluid guide is designed at least to guide a hot fluid to and / or in the application unit; and / or

[0082] - that the hot fluid guide is at least designed to guide a hot fluid into at least two areas of the application unit, wherein in particular the at least two areas can assume different relative positions to one another due to the flexible design.

[0083] In some advantageous embodiments, the attachment for a hot fluid device forms at least partially the hot fluid guide.

[0088] In particular, the supply part comprises a guide chamber section for the hot fluid. Advantageously, the guide chamber section of the supply part is fluid-conductingly connected, in particular directly and / or indirectly, to the cavity in the application unit, which is designed in particular as an outlet chamber area.

[0089] Preferably, a distributor section is provided. In particular, the hot fluid guide comprises the distributor section.

[0090] Conveniently, the attachment for a hot fluid device includes the distributor section.

[0091] In particular, the distributor section comprises at least one guide chamber section for a hot fluid. Advantageously, the distributor section is designed to distribute hot fluid, in particular to distribute it into different sections of the application unit and / or into different spatial regions of the cavity, which is designed, in particular, as an outlet chamber. Preferably, at least two of these different sections and / or spatial regions can assume different relative positions to one another due to the flexible design.

[0092] Preferably, the distributor section forms a plurality of distributor openings.

[0093] In particular, at least one of the following is provided for:

[0094] - that at least some of the plurality of distributor openings of the distributor section lead out of the guide space section of the distributor section and / or open into the cavity of the application unit, which cavity is designed in particular as an outlet space area; and / or

[0095] - that at least one distributor opening opens into at least some of the several cavity regions of the cavity, which is designed in particular as an outlet space region, wherein advantageously at least two of the at least some cavity regions can assume different relative positions to one another due to the flexible design; and / or

[0097] This advantageously improves the distribution of the supplied hot fluid, for example, into different spatial areas and / or for large-area applications. For example, it is advantageous for the supplied hot fluid to first be guided through the distributor section and then fed via its distributor openings into different spatial areas of the cavity, which is particularly designed as an outlet area, in order to enable a more even distribution of the hot fluid throughout the cavity.

[0098] In particular, the distribution section is provided with at least one of the following:

For example, a wall of the distributor section surrounding the fluid guide space section separates the fluid guide space section of the distributor section from the spatial regions into which the hot fluid is distributed.

[0102] In particular, at least one of the following is provided:

[0103] - that a guide space section of the supply part, which is provided in particular for supplying hot fluid, opens into the guide space section of the distributor section; and / or that the supply part at least co-forms the distributor section.

[0104] In advantageous embodiments, the application unit is mounted so as to be rotatable about a rotation axis at least partially, in particular at least within a permissible rotation range.

[0105] For example, this improves handling for a user, since the application unit can at least partially adapt its orientation due to the rotatable mounting of an object to be treated, for example an orientation of a surface of this object.

[0119] Advantageously, the application unit is fixed in a certain orientation with regard to its at least partial rotatability, as long as it is not displaced from this orientation by external influences. This advantageously makes handling more comfortable for the user.

[0120] For example, the application of force, for example by fixing the application unit in an orientation (provided that no external influences counteract this fixing), increases the stability of the design.

To the extent that the pivotable arrangements are at least substantially identical, they will be described jointly below, and a differentiation of the segments 2521, 11, 111 and the respective pivot axes 2621, 111 will be omitted for the sake of simplicity.

[0186] Conveniently, the two pivot axes 26211, 111 run at least approximately parallel to one another.

[0191] For example, the pivot arm 274 is formed by the segment body 254 of the segment 252 forming the pivot arm 274.

[0192] By way of example, a pivoting device 268 with a guide section 282, a sliding section 286 and stops 284 can be seen in Figs. 5 and 6.

[0193] For example, the pivoting device 268 comprises a guide section 282, which extends along a section of the pivot axis 262 in the axial direction and is curved in the circumferential direction within an angular range around the pivot axis 262.

In particular, the sliding section 286 is movably mounted between the two stops 284.

[0195] For example, the sliding portion 286 extends longitudinally in the axial direction of the pivot axis 262 and advantageously along the longitudinal extent of the guide portion 282. In particular, in a pivoting device 268 by which two segments 252 are arranged pivotably relative to one another, the guide portion 282 is formed by one of the two relatively pivotable segments 252, and the sliding portion 286 is formed by the other of the two relatively pivotable segments 252. Advantageously, the segment 252 that forms the guide portion 282 also forms the stops 284.

[0196] For example, the middle segment 2521 forms the guide section 282 and an outer segment, for example the segment 254II and / or the segment 254III, a corresponding sliding section 286.

[0197] Conveniently, the guide portion 282 and / or at least one of the stops 284 is formed by the segment body 254 of the segment 252 forming the guide portion 282 and / or the stop 284.

[0200] By way of example, Fig. 6 shows the application unit 202 with segments 252 pivoted out of the home position. The middle segment 2521 and an outer segment 252II are pivoted relative to each other along their entire permissible pivoting range, and the sliding section 286 rests against a corresponding stop 284.

[0206] In particular, a respective outlet chamber 314 of the outlet space region 312 is formed in the interior of at least some segments 252, advantageously in each segment 252. For example, segment 2521 has an outlet chamber 3141, segment 252II has an outlet chamber 31411, and segment 252III has an outlet chamber 314III. For example, an outlet chamber 314 of a segment 252 is formed in the segment body 254 of this segment 252. For example, the cover plate 256 of this segment 252 at least partially covers this cavity, preferably in the area of ​​the application region 232. Advantageously, a corresponding outlet passage 234 is formed in the uncovered area of ​​the cavity.

[0207] Advantageously, a distributor section 322 of a hot fluid supply is provided.

[0208] The distributor section 322 has a plurality of distributor openings 324. The distributor openings 324 lead out of a fluid guide chamber section 326 of the distributor section 322. A wall 328 of the distributor section 322 surrounds the fluid guide chamber section 326 and at least partially forms the distributor openings 324.

[0209] To form the fluid guide chamber section 326 in an injection-molded part, for example, an opening in the injection-molded part is larger than a provided distributor opening 324, and an insert body 332 is inserted into this opening of the injection-molded part, which at least co-forms the distributor opening 324. This is illustrated by way of example in Fig. 5 at the distributor opening 324III.

[0210] Advantageously, the distributor section 322 extends at least partially into the cavity of the outlet space region 312. The fluid guide space section 326 is separated from other spatial regions of the cavity by the wall 328 and is fluid-conductingly connected to at least some spatial regions of the outlet space region through the distributor openings 324.

[0211] Advantageously, the distributor openings 324 open into different sub-regions of the cavity of the outlet space region 312. At least some sub-regions into which at least one distributor opening 324 opens are such sub-regions of the cavity which can assume different relative positions to one another due to the flexible design of the application unit 202.

[0212] Conveniently, at least one distributor opening 324 of the distributor section 322 opens into each of the outlet chambers 314 of the plurality of segments 252.

[0213] For example, the distributor section 322 extends elongately in a longitudinal direction thereof.

[0214] Conveniently, the distributor section 322 has at least one distributor opening 324 at each of its opposite longitudinal ends relative to the longitudinal direction of extension. Conveniently, the distributor section 322 has at least one distributor opening 324 in a central section, wherein the central section is arranged between end sections of the distributor section 322 relative to the longitudinal direction of extension of the distributor section 322.

[0215] In particular, the distributor section 322 is arranged at least with its central section in the middle segment 2521 and at least one distributor opening 324 in the middle section opens into the outlet chamber 3141 of the middle segment 2521.

[0216] In particular, the distributor opening 324 opens into an outlet chamber 31411,111 of an outer segment 25211,111 at a longitudinal end of the distributor section 322 relative to the longitudinal extension direction.

[0217] Advantageously, the longitudinal direction of the distributor section 322 runs transversely and in particular at least approximately perpendicular to the axial direction of the pivot axis 262 of two segments 252 arranged so as to be pivotable relative to one another. In particular, the distributor section 322 projects with one longitudinal end, advantageously only slightly, into an outlet chamber 31411,111 of a corresponding outer segment 25211,111. Advantageously, one longitudinal end of the distributor section 322 projects, advantageously only slightly, beyond a geometric plane, wherein the corresponding geometric plane contains a pivot axis 262 and runs at least approximately perpendicular to the longitudinal direction of the distributor section 322.

[0218] Preferably, the feed part 214 also forms the distributor section 322.

[0219] Conveniently, a fluid guide space section in the supply part 214, preferably in the central section of the distributor section 322, opens into the fluid guide space section 326 of the distributor section 322.

[0220] Preferably, the application unit 202 is arranged to be rotatable about a rotation axis 342 on the distributor section 322 and in particular on the feed part 214 and is mounted to be rotatable about the rotation axis 342 at least within a permissible rotation range relative to the distributor section 322 and to the feed part 214.

[0221] Since the feed part 214 can be at least fastened to the feed unit 134, which has the handle 138, the application unit 202 is also mounted so as to be rotatable about the rotation axis 342, at least within the permissible rotation range relative to the handle 138.

[0222] Conveniently, the rotatable mounting of the application unit 202 is formed on the distributor section 322. In particular, the axis of rotation 342 runs at least approximately parallel to the longitudinal direction of the distributor section 322. Conveniently, the axis of rotation 342 runs transversely and, for example, at least approximately perpendicularly to the axial direction of a pivot axis 262 of two segments 252 arranged pivotably relative to one another. For example, the axis of rotation 342 runs at least approximately parallel to at least a portion of the geometric application surface. For example, the axis of rotation 342 runs parallel to an extension direction 242, here to the extension direction 2421, at least in the region of the central segment 2521.

[0223] In particular, the application unit 202 is biased into a basic orientation with respect to its rotatability about the rotation axis 342.

[0224] For example, a spring 346 is provided for this purpose. The spring 346 is advantageously tensioned between the application unit 202, for example, the middle segment 2521, and the distributor section 322. The spring 346 can be seen as an example in Figs. 4 and 5.

[0225] In particular, a structure and a function of a hot fluid device 100 and a hot fluid device attachment 210 and, for example, advantages thereof are briefly summarized as follows.

[0226] In particular, the hot fluid device 100 comprises a hot fluid generating unit and, for example, a hot fluid supply device 122.

[0227] Conveniently, the hot fluid generation unit provides a hot fluid. Conveniently, the hot fluid is supplied to the application unit 202 and, for example, to the hot fluid device attachment 210 via the hot fluid supply device 122.

[0228] Conveniently, the temperature of the hot fluid is at least 60°C, in particular at least 80°C, and advantageously at least 95°C. In particular, the hot fluid is a fluid mixture with, in particular, gaseous and / or liquid components. In particular, the hot fluid comprises water, for example, with or without additives.

[0229] The application unit 202 is designed to apply the supplied hot fluid (directly and / or indirectly), in particular, to an object. In particular, the application unit 202 is designed to clean the object, in particular an object and / or a surface, upon application of the hot fluid.

[0230] In particular, the application unit 202 comprises the application region 232, in which outlet passages 234 for the hot fluid are advantageously formed. In particular, the application region 232 of the application unit 202 borders an application environment 238 of the application unit 202, wherein the hot fluid is applied in the application environment 238. In particular, the object to which the hot fluid is applied, in particular the object and / or the surface to be cleaned, is located in the application environment 238.

[0231] Advantageously, the application unit 202 is designed to be flexible in shape at least in sections and in particular is designed to be flexible in shape such that the application region 232 is flexible in shape at least in sections and can thus advantageously assume different shapes.

[0232] In particular, one advantage of this is that, due to the shape flexibility, the application unit 202, and in particular the application region 232, can at least partially adapt its shape to a shape of the object in the application environment 238. This advantageously improves the application of the hot fluid and, for example, the cleaning of the object and / or surface.

[0233] In particular, the flexible design of the application unit 202, and in particular of the application region 232, is advantageous for application to an object with a surface that is at least partially convex and / or at least partially concave. This flexibility of shape is particularly advantageous for the application of the hot fluid and, in particular, for cleaning a surface that is at least partially concave, in order to better reach the interior regions of the concave surface.

[0234] In particular, at least one cavity is formed in the application unit 202 as an outlet area 312 for the hot fluid. Conveniently, the hot fluid is fed into the outlet area 312 and exits therefrom, in particular through the outlet passages 234, into the application environment 238 for application of the hot fluid.

[0235] In particular, the exit space region 312 comprises a plurality of hollow space regions, for example at least partially connected and / or separated from one another.

[0236] In particular, hollow spatial regions of the exit space region 312 assume different relative positions to one another in the case of different shapes that can be assumed by the application unit 202 and / or by the application region 232.

[0237] Conveniently, at least some exit passages 234 are arranged in different sections of the application region 232, wherein these different sections of the application region 232 assume different relative positions relative to one another in the case of different shapes that can be assumed by the application unit 202 and / or by the application region 232.

[0238] This advantageously allows hot fluid to be applied at multiple locations on differently shaped objects, particularly those with a curved surface. In particular, a distributor section 322 is provided.

[0239] Conveniently, at least one fluid guide chamber section 326 is formed in the interior of the distributor section 322 for guiding the hot fluid. In particular, distributor openings 324 lead from the fluid guide chamber section 326 into hollow spatial regions of the outlet space region 312. In particular, at least one distributor opening 324 of the distributor section 322 opens into different spatial regions of the outlet space region 312, wherein these different spatial regions assume different relative positions relative to one another for different shapes that can be assumed by the application unit 202 and / or the application region 232.

[0240] In particular, a favorable distribution of the hot fluid into different spatial areas of the outlet space area 312 can be achieved in this way.

[0241] In particular, the hot fluid is advantageously supplied to the application unit 202 via the supply part 214, as is sketched by way of example in Fig. 3 with the arrow 362.

[0242] In particular, the supplied hot fluid is distributed in the distributor section 322 and guided to the different distributor openings 324, as is sketched by way of example in Fig. 3 with the arrows 364.

[0243] In particular, the hot fluid enters, for example at the different distributor openings 324, into different cavity regions of the outlet space region 312, as is sketched by way of example in Fig. 3 with the arrows 366.

[0244] From these hollow spaces of the exit space area 312 emerges the

[0245] Hot fluid is discharged via the outlet passages 234 into the application environment 238. For example, the application unit 202 comprises a plurality of segments 252, which are advantageously mounted so as to be at least partially movable relative to one another.

[0246] Conveniently, each of at least some, for example all, of the plurality of segments 252 comprises at least one hollow space region of the exit space region 312 and / or at least one exit passage 234.

[0247] In particular, the segments 252 which are movable relative to one another advantageously achieve a shape flexibility of the application unit 202 and in particular of the application region 232.

[0248] For example, at least some segments 252 are at least largely rigid. For example, at least some segments 252 include a rigid segment body 254.

[0249] Conveniently, at least two segments 252 are pivotable relative to each other about a pivot axis 262 at least within a permissible pivoting range. For example, stops 284 are provided, which in particular define a respective end of the permissible pivoting range.

[0250] Advantageously, a stop 284 prevents excessive pivoting, for example beyond the permissible pivoting range, of at least two segments 252 relative to one another.

[0251] Advantageously, at least parts of the application unit 202, for example, its segments 252, are biased into a home position. In particular, the application unit 202, and in particular the application region 232, thus assume a shape corresponding to the home position without any external influence. For example, the application region 232 is at least largely flat in the home position.

[0252] Advantageously, a shape of the application unit 202 and in particular of the application region 232 which is favorable for the application of the hot fluid is determined by the application.

[0253] Advantageously, the application unit 202, and in particular the application region 232, can be displaced from the home position, particularly by an external influence, and assume a different shape. When the cause of the deformation, in particular the external influence, no longer exists, the application unit 202 is advantageously returned to its home position by the application of the force.

[0254] In particular, the deformation-causing influence is a curved surface of an object to which the hot fluid is applied. In particular, the application region 232 contacts the object (directly and / or indirectly) during the application of the hot fluid and, advantageously, adapts at least partially to the shape of the object due to its shape flexibility.

[0255] Preferably, the application unit 202 is mounted at least partially rotatable about a rotation axis 342, for example within a permissible rotation range.

[0256] Preferably, the application unit 202 is mounted relative to a part forming a handle 138 about the rotation axis 342. For example, the application unit 202 is mounted at least partially about the rotation axis 342 relative to the supply part 214 for supplying hot fluid.

[0257] In particular, the at least partially rotatable mounting of the application unit improves handling of the application unit and, for example, of the hot fluid device attachment 210 with the application unit 202. This is because a user can guide the application unit 202 in a position that is convenient for them and, for example, hold the handle 138. Nevertheless, the application unit 202 can, in particular independently of the user's hand position, at least within the permissible rotation range, at least partially adapt its orientation to the orientation of a surface to which the hot fluid is to be applied and which, in particular, is to be cleaned.
