[0006] DE 10 2017 107 345 Al discloses a floor nozzle for a steam cleaner.

[0007] WO 2008 / 065619 A1 discloses a steam device. The object underlying the invention is to improve a hot fluid device attachment and a hot fluid device, as well as uses thereof.

[0008] The underlying object is achieved in embodiments of the invention by a hot fluid device attachment and / or a hot fluid device with a hot fluid device attachment and / or by using a hot fluid device attachment and / or by using a hot fluid device with a hot fluid device attachment, wherein the hot fluid device attachment comprises a hot fluid guide for guiding a hot fluid, for example from an inlet and / or to an outlet region, and wherein the hot fluid guide is designed to be angled at least in sections.

[0009] The underlying problem is solved in embodiments of the invention by a hot fluid device attachment and / or by a hot fluid device and / or by the use of a hot fluid device attachment and / or by the use of a hot fluid device with a hot fluid device attachment, wherein the hot fluid device attachment has a hot fluid guide for guiding a hot fluid and a separation device, in particular for at least partially separating liquid components in a hot fluid guided through the hot fluid guide. In particular, the hot fluid guide is designed to guide the hot fluid from an inlet and / or to an outlet region.

[0010] Advantageously, the separating device is arranged at least partially in the hot fluid guide, which is advantageously designed to be angled at least in some sections. Preferably, the hot fluid is guided through the separating device at least in some sections in angled sections.

[0011] In particularly advantageous embodiments, combinations of the features explained above and below are formed.

[0012] In particular, an advantage of embodiments of the solution according to the invention is that the hot fluid reaching the outlet region has at least fewer liquid components, since the hot fluid has flowed through at least one angled section, preferably through several angled sections, and / or through the separation device and in the process, liquid components have been advantageously separated from the hot fluid.

[0013] In particular, the hot fluid is supplied to an application in the outlet area and in particular applied to an object.

[0014] In advantageous embodiments, the hot fluid for treating garments, in particular for at least partially ironing a garment and, for example, in some embodiments, for at least partially cleaning a garment, is applied to a garment at least substantially in the outlet region. It is advantageous here if a hot fluid that is as gaseous as possible, in particular steam, with at most a very small proportion of liquid components, i.e., in particular steam that is as dry as possible, is applied to the garment.

[0015] In preferred embodiments, at least one of the following is provided:

[0016] - that in at least one angled section, in particular in at least some angled sections, a guide direction for a hot fluid is subjected to a change in its orientation by at least 70°, in particular by at least approximately 90°; and / or

[0017] - that in at least one angled section, in particular in at least some angled sections, a guide direction for a hot fluid is subjected to a change in its orientation by more than 100°, in particular by at least approximately more than 110°; and / or

[0018] - that at least one separation element of the separation device is arranged in the hot fluid guide and wherein, in particular, at least one separation element, in particular at least some separation elements, a guide direction for a hot fluid is subjected to a change in its orientation and / or a guided hot fluid is deflected; and / or

[0019] - that the hot fluid guide leads from an inlet and / or to an outlet area.

[0020] For example, gaseous components of the hot fluid can flow past more easily than liquid components of the hot fluid in such an angled configuration, so that at least some liquid components are separated from the hot fluid.

[0021] Advantageously, at least three, preferably at least four, in particular at least five, for example at least six, sections are provided with a change in the orientation of the guide direction by at least 70°, in particular by at least approximately 90°.

[0022] Advantageously, at least two sections are provided with a change in the orientation of the guide direction by at least 100°, in particular by at least approximately more than 110°.

[0023] In particular, the angle of change in the orientation of the guidance direction between the vector of the guidance direction before the change and the vector of the guidance direction after the change is measured.

[0024] In advantageous embodiments, at least one impact plate is arranged in the hot fluid guide. In particular, at least one impact plate is part of the separation device as a separation element. Preferably, a hot fluid guided along the hot fluid guide is guided at least substantially perpendicularly to the impact plate.

[0025] For example, one advantage of this is that liquid components in the hot fluid are slowed down in speed upon impact with the impact plate and advantageously the slowed down liquid components can be better separated from the hot fluid and / or the slowed down liquid components are atomized and / or evaporated.

[0026] Preferably, at least one of the following is provided:

[0027] - that at least one particularly large free space section is formed laterally of the impact plate into a guide space for the hot fluid guide; and / or

[0028] - that a hot fluid guided along the hot fluid guide is guided away from the impact plate at least approximately perpendicularly with respect to the guide direction behind the impact plate; and / or

[0029] - that a guide contour of the hot fluid guide leads past the impact plate and wherein, in particular, a guide direction of the guide contour is aligned at least approximately the same along a section of the guide contour leading to the impact plate and along a section of the guide contour leading away from the plate; and / or

[0030] - that the impact plate in the hot fluid guide is the first element along the course of the guide contour with respect to the guide direction at which the guide direction is subject to a change in its orientation, and / or that along the guide contour with respect to the guide direction, the impact plate is the first arranged element of the separation device; and / or

[0031] - that a hot fluid supplied at the inlet in an inlet direction is first guided onto the impact plate and, in particular, is guided at least approximately perpendicularly onto the impact plate in this inlet direction.

[0032] In particular, one advantage of this is that the gaseous components of the hot fluid can be guided past the impact plate and / or at least approximately perpendicularly away from the plate more easily and at least partially liquid components are thereby separated from the hot fluid.

[0033] In particular, an advantage of at least one particularly large free space section lateral to the impact plate is that liquid components of the hot fluid, which are fed to the impact plate and, in particular, bounce off it, have a free space into which they can enter. For example, the liquid components that enter the free space are at least partially separated from the hot fluid. It is particularly advantageous if the liquid components that enter the free space at least partially evaporate and / or atomize in the free space and thus continue to flow along the guide contour in an atomized and / or evaporated state.

[0034] It is particularly advantageous if at least one particularly large free space section extends laterally from the impact plate with an extent that is at least as large, preferably at least twice as large, as the extent of the impact plate. In particular, the extent of the impact plate is measured perpendicular to the direction in which the hot fluid is directed onto the impact plate.

[0035] Preferably, at least one particularly large-scale free space section is provided and particularly preferably two particularly large-scale free space sections are provided, which extend at least approximately semicircularly laterally from the impact plate.

[0036] In particular, it is advantageous to first guide the hot fluid to the impact plate, since the hot fluid is often supplied at a high velocity, for example, from a hot fluid supply device at the inlet. This advantageously reduces the high supply velocity of the hot fluid at the impact plate, and advantageously, the hot fluid is further supplied at a reduced velocity through the hot fluid guide, preferably to further separation elements. In preferred embodiments, at least one separation plate is arranged in the hot fluid guide, wherein, in particular, the separation plate, as a separation element, is part of the separation device.

[0037] A particular advantage of this is that liquid components are at least partially separated from the hot fluid at the separation plate.

[0038] Preferably, at least one of the following is provided:

[0039] - that at least one separating plate is aligned, in particular at an acute angle obliquely to the direction of flow of a hot fluid supplied to the separating plate; and / or

[0040] - that in at least one separating plate, a hot fluid guided along the guide contour is guided at least partially along the separating plate, wherein in particular a guide along the separating plate is designed to at least partially separate liquid components of the hot fluid; and / or

[0041] - that at least one separating plate is designed and / or arranged to exert a flow resistance, wherein the exerted flow resistance is exerted on a hot fluid guided along the guide contour; and / or

[0042] - that with at least one separating plate at one end of the guide along the separating plate, the hot fluid is guided along the guide contour at an angle past the separating plate, wherein preferably the hot fluid guide is guided past the separating plate at an obtuse angle and / or the guide direction is subject to a change in its orientation by an obtuse angle; and / or

[0043] - that in at least one separating plate, a component of the guide direction is oriented opposite to the guide direction of the hot fluid supplied to the separating plate when guided along the separating plate; and / or

[0044] - that at least one separation plate is arranged obliquely to a height direction of the hot fluid device attachment.

[0045] This advantageously improves the separation of liquid components from the hot fluid.

[0046] For example, an angle at which a separation plate is aligned obliquely to the height direction is at least 10°, in particular at least 20°, for example at least 30°, and / or at most 70°, for example at most 60°.

[0047] In particularly advantageous embodiments, at least one filter is arranged in the hot fluid guide, in particular as a separation element of the separation device.

[0048] A particular advantage of this is that the filter at least reduces the flow of liquid components of the hot fluid through it. For example, liquid components are at least partially prevented from flowing through the filter, in particular by its filter material. For example, liquid components of the hot fluid are separated from the flowing hot fluid as they flow through the filter, in particular by its filter material.

[0049] Preferably, at least one of the following is provided:

[0050] - that at least one filter comprises a hydrophobic filter material; and / or

[0051] - that in at least one filter, filter passage openings, in particular filter passage openings in the filter material of the filter, have an extension of at least 1 / m and / or an extension of at most 500 / μm, for example an extension of at least approximately 50 μm, transversely to a passage direction; and / or

[0052] - that in at least one filter, with respect to the guide direction along the guide contour, at least one separation element and / or an angled section is arranged in front of the at least one filter, in particular between the inlet and the filter, and / or at least one separation element and / or an angled section is arranged after the at least one filter, in particular between the filter and the outlet area; and / or

[0053] - that a support structure holds at least one filter, in particular a filter material of the filter, in its position, wherein in particular the support structure secures the filter, in particular a filter material of the filter, at least against a change in position in the guide direction and / or wherein in particular the support structure at least partially supports the at least one filter, in particular a filter material of the filter, on an outlet side of the filter, wherein a hot fluid flowing through the filter exits the filter again at the outlet side.

[0054] In particular, one advantage of a hydrophobic filter material is that the risk of accumulation of particularly separated liquid components in the filter material is at least reduced and thus advantageously associated risks such as contamination and / or rot are at least reduced.

[0055] In particular, a separation element arranged upstream of the filter and / or an angled section is advantageous in that the velocity of the supplied hot fluid is at least reduced upstream of the filter and / or liquid components are already separated from the hot fluid, thus at least reducing the risk of overloading the filter material of the filter. It is particularly advantageous if at least one filter is arranged adjacent to a free space section near the impact plate, so that, for example, the filter at least reduces the escape of liquid components from the free space section toward the guide contour.

[0056] For example, one advantage of a separation element arranged downstream of the filter and / or of an angled section is that the filter preferably already separates some liquid components from the hot fluid and subsequently any remaining liquid components are at least partially separated by at least one element and / or section which is preferably specifically designed for this purpose.

[0057] For example, with respect to the guide direction along the guide contour, the separation plate is arranged after a filter.

[0058] For example, a filter material is arranged in a frame and conveniently attached.

[0059] Preferably, the at least one support structure is provided in addition to the frame, in particular to provide additional security and / or fastening.

[0060] In favorable embodiments, the hot fluid device attachment has an outlet section with outlet openings. The outlet openings conduct fluid from a section of the hot fluid guide, in particular a guide section, to the outlet area.

[0061] In particular, the outlet openings lead from a section of the hot fluid guide located inside the housing of the hot fluid device attachment to the outlet area located outside the housing.

[0062] In particular, at least one of the following is provided: - that an outlet chamber is formed on the inside of the outlet section relative to the housing of the hot fluid device attachment, i.e. that in particular the section of the hot fluid guide from which the outlet openings lead to the outlet area is formed as an outlet chamber; and / or

[0063] - that, with respect to a height direction of the hot fluid device attachment, the outlet openings are formed in an upper region of the outlet section and / or open into an upper region of the outlet chamber; and / or

[0064] - that the outlet openings are formed above a cumulation chamber in relation to a height direction of the hot fluid device attachment, wherein in particular the cumulation chamber is formed in the outlet chamber and in particular in a lower region of the outlet chamber; and / or

[0065] - that the hot fluid is guided along the guide contour relative to the height direction of the hot fluid device attachment at least substantially at the level of the outlet openings and / or from above the outlet openings to the outlet openings; and / or

[0066] - that the hot fluid is guided along the guide contour in a direction relative to the height of the hot fluid device attachment in the upper area of ​​the outlet chamber and / or that the hot fluid is guided along the guide contour relative to the height of the hot fluid device attachment above the accumulation chamber to the outlet openings.

[0067] For example, forming the outlet openings in an upper region and / or guiding the hot fluid in an upper region and / or from above to the outlet openings is advantageous, as this favorably allows liquid components in the hot fluid to at least partially sink downwards and thus not reach the outlet area through the outlet openings. For example, providing a collection space at the outlet section is advantageous, as liquid components separated in this space, for example, before and / or at the outlet section, can collect in the collection space.

[0068] In particular, the upper region of the outlet section is located in an upper half, preferably in an upper third, of the outlet section with respect to the height direction.

[0069] In particular, the upper region of the outlet chamber is located in an upper half, relative to the height direction, preferably in an upper third, for example in an upper quarter, of the outlet chamber.

[0070] In particular, the lower region of the outlet chamber is located in a lower half, for example in a lower third, of the outlet chamber in relation to the height direction.

[0071] In some advantageous embodiments, at least one of the following is provided:

[0072] - that the outlet section is made of a metallic material; and / or

[0073] - that an edge section at least partially surrounds the outlet section, wherein in particular the outlet section is set back from at least a partial section of the edge section, wherein in particular the outlet section extends at least substantially in a geometric plane and at least a partial section of the edge section protrudes beyond this geometric plane, wherein in particular the edge section is at least partially formed from a housing part of the hot fluid device attachment.

[0074] For example, one advantage of a metallic outlet section is that it is a good thermal conductor and thus, for example, heat given off by the hot fluid to the outlet section is transferred via the outlet section into the outlet area.

[0075] For example, one advantage of a recessed outlet section is that, when using the hot fluid device attachment, the risk of the outlet section coming into contact with an object to which the hot fluid is applied, in particular the risk of the outlet section coming into contact with, for example, a sensitive item of clothing, is at least reduced.

[0076] In particular, the outlet section is preferably arranged in a fluid-tight manner on at least one housing part and, for example, is attached thereto. Advantageously, the at least one housing part on which the outlet section is arranged forms the edge section at least in sections.

[0077] In advantageous embodiments, the hot fluid device attachment comprises a liquid collecting device with at least one collecting chamber, in particular for separated liquid components from the hot fluid.

[0078] Advantageously, liquid components separated in the angled configuration and / or in the separation device can be collected.

[0079] Advantageously, the collecting space is formed at a distance from the hot fluid guide and preferably at a distance from the guide space thereof.

[0080] Advantageously, the collecting chamber is arranged in the interior of the housing of the hot fluid device attachment.

[0081] Advantageously, this liquid collection device is designed such that separated liquid components from the hot fluid guide and / or from the separation device are guided through the liquid collection device to the collection chamber. Preferably, the liquid collection device provides at least one of the following:

[0082] - that at least one section of the hot fluid guide and / or at least one area around at least one separation element of the separation device is fluidically connected to the at least one collecting chamber, wherein in particular the at least one fluid-conducting connection is oriented at least substantially downwards relative to a height direction of the hot fluid device attachment in the direction of the collecting chamber; and / or

[0083] - that the collecting space is arranged in a lower region of the hot fluid device attachment and / or in a lower region of the housing interior of the housing of the hot fluid device attachment, relative to a height direction of the hot fluid device attachment.

[0084] This is particularly advantageous for removing liquid components from the hot fluid guide and / or from the separation device.

[0085] In particular, a removal of the liquid components and / or a collection thereof is at least partially assisted by gravity if the fluid-carrying connection is oriented at least substantially downwards and / or the collection space is arranged at the bottom.

[0086] In particular, the lower area of ​​the hot fluid device attachment is located in a lower half of the hot fluid device attachment in relation to the height direction.

[0087] In particular, the lower area of ​​the housing interior is located in a lower half of the housing interior in relation to the height direction.

[0088] In particularly advantageous embodiments, the liquid collection device has at least one venting channel that opens into the collection chamber. Advantageously, the venting channel leads away from the collection chamber.

[0089] In particular, at least one of the following is provided for:

[0090] - that the ventilation duct opens into an upper area of ​​the collecting chamber in relation to the height direction of the hot fluid device attachment; and / or

[0091] - that the venting channel leads to a section of the hot fluid guide and in particular opens into this section, wherein in particular this section of the hot fluid guide is the outlet chamber.

[0092] In particular, a vent duct is a duct separate from a collecting duct.

[0093] In particular, a benefit of the venting duct is that it allows a gas mixture to escape from the collection chamber when liquid components are fed into the collection chamber through a collection duct.

[0094] In particular, one advantage of a venting channel opening into an upper area is that the risk of liquid components escaping from the collecting space through the venting channel is at least reduced.

[0095] In particular, the upper region of the collecting space is located in an upper half, relative to the height direction, preferably in an upper third, for example in an upper fifth, of the collecting space.

[0096] It is particularly advantageous if the ventilation duct opens into the collecting chamber at an upper side in relation to the height direction.

[0097] In particular, a venting channel leading into the hot fluid guide is that gaseous components of the hot fluid that have entered the collection chamber can flow back to the hot fluid guide. In favorable embodiments, at least one of the following is provided:

[0098] - that the liquid collecting device comprises at least one display unit for at least partially displaying a fill level of a liquid in the collecting space; and / or

[0099] - that a drain is provided at the collecting chamber.

[0100] In particular, one advantage of a fill level display unit is that a user of the hot fluid device attachment and / or the hot fluid device can at least partially detect the fill level in the collection chamber and at least detect that a tolerable fill level threshold has been exceeded and the collection chamber would have to be emptied.

[0101] In particular, a display of the display unit is visible from an area surrounding the hot fluid device attachment.

[0102] In some advantageous embodiments, a housing section in the collecting chamber is designed in such a way that the fill level in the collecting chamber can be at least partially seen through it.

[0103] In some particularly advantageous embodiments, the liquid collection device has a plurality of display units, with preferably at least two display units on opposite sides of the hot fluid device attachment having at least their display. A particular advantage of this is that a user can at least partially determine the fill level from different viewing directions.

[0104] A drain in the collection chamber is particularly advantageous in order to be able to empty the collection chamber.In preferred embodiments, the underlying object is achieved (alternatively and / or additionally) by a hot fluid device attachment and / or by a hot fluid device and / or by using a hot fluid device attachment and / or by using a hot fluid device with a hot fluid device attachment, wherein the hot fluid device attachment comprises a hot fluid guide for guiding a hot fluid and, for example, a liquid collecting device, wherein the hot fluid guide, in particular at least its guide space, and / or the liquid collecting device, in particular at least its collecting space, is arranged in the housing interior of the housing of the hot fluid device attachment at least partially in a heat-transfer-reducing manner relative to an outer wall of the housing of the hot fluid device attachment and / or is arranged at a distance from an outer wall of the housing of the hot fluid device attachment.

[0105] In particular, at least one of the following is provided for:

[0106] - that at least the guide chamber of the hot fluid guide and / or at least the collecting chamber of the liquid collecting device is at least partially, in particular at least largely, separated by a double wall from the surroundings of the hot fluid device attachment; and / or

[0107] - that at least one intermediate space is formed at least in sections between the hot fluid guide, in particular at least its guide space, and / or the liquid collecting device, in particular at least its collecting space, on the one hand, and an outer wall of the housing of the hot fluid device attachment, in particular an outer wall section which is arranged closest to the guide space and / or collecting space, on the other hand; and / or

[0108] - that the liquid collection device comprises a collection container, wherein the at least one collection chamber is formed in an interior of the collection container, and wherein the collection container is arranged in the housing interior of the housing of the hot fluid device attachment. A particular advantage of this is that heat conduction, for example from the hot fluid in the guide chamber and / or from the hot fluid in the collection chamber to an outer wall of the housing of the hot fluid device attachment is at least reduced. For example, the outer wall heats up at least less and preferably only heats up slightly at most, so that a risk to a user when using the hot fluid device attachment is at least reduced. For example, at least the guide chamber and / or the collection chamber are better thermally insulated from the surroundings of the hot fluid device attachment, so that less heat is extracted from the hot fluid therein.

[0109] In particular, the hot fluid guide comprises a guide device, wherein the guide device comprises in particular at least the guide space of the hot fluid guide and parts delimiting the guide space.

[0110] In particularly advantageous embodiments, it is provided that at least the guide device of the hot fluid guide and / or the separation device and / or the liquid collection device is / are designed as a device insert which is arranged in the housing interior of the housing of the hot fluid device attachment and / or is / are designed as an insert assembly, preferably is / are designed as a common insert assembly.

[0111] For example, one advantage of this is that the device can be designed in a cost-effective manner according to its requirements and can then be arranged inside the housing, particularly as a separate assembly from the housing. For example, the device insert is inserted into the housing interior and / or the housing is assembled around the device insert from housing parts.

[0112] For example, the devices can be designed together in a compact manner in an integral device insert and / or an integral insert assembly. Advantageously, the housing can thus be designed separately from the devices arranged therein, specifically in accordance with the requirements for the housing.

[0113] In favorable embodiments, at least one of the following is provided:

[0114] - that the outlet area and the inlet are formed on opposite sides of the hot fluid device attachment, in particular on opposite sides of the housing of the hot fluid device attachment, wherein in particular the opposite sides are opposite sides with respect to a longitudinal direction of the hot fluid device attachment; and / or

For example, the housing of the hot fluid device attachment is formed from at least one housing part. In particular, at least one housing part, and advantageously at least some housing parts, are made of plastic.

[0153] In particular, the dispensing element 148 comprises an outlet nozzle 154 through which the hot fluid supply device 122 dispenses the hot fluid and through which the hot fluid exits.

[0154] An example of a dispensing element 148 is shown in Fig. 2.

[0155] In particular, a hot fluid device attachment designated as a whole by 210 is provided.

[0156] By way of example, a hot fluid device attachment 210 is shown in a state assembled with the hot fluid supply device 122 of the hot fluid device 100 in Figs. 1 and 2, and the hot fluid device attachment 210 is shown separately in Figs. 3 to 8.

[0158] In particular, in such variants, the hot fluid device attachment 210 comprises at least the actuating device 142 and / or the connecting part 132, advantageously with a connecting part 136.

[0159] In particular, the hot fluid device attachment 210 comprises a housing, designated as a whole by 214, which is preferably formed from a plurality of housing parts 216. For example, the housing parts 216 are plastic parts and / or shell parts.

[0160] Conveniently, the housing 214 defines a housing interior 218, wherein the housing interior is surrounded by the housing parts 216.

[0161] Advantageously, at least most of the technical equipment of the hot fluid device attachment 210 is arranged at least largely in the interior of the housing.

[0162] In particular, the housing parts 216 each comprise at least one outer wall section 224. The outer wall sections 224 form an outer wall of the housing 214, wherein the outer wall separates the housing interior 218 from an environment of the hot fluid device attachment 210.

[0163] In particular, a vertical direction 232 and / or a longitudinal direction 234 and / or a transverse direction 236 are defined in the hot fluid device attachment 210, for example, by its housing 214 and / or by its technical equipment and / or by an intended proper use of the hot fluid device attachment 210. In particular, the vertical direction 232 and the longitudinal direction 234 and the transverse direction 236 each run perpendicular to one another.

[0164] In particular, the height direction 232 is defined by the proper use of the hot fluid device attachment 210 and / or by the design of the technical equipment of the hot fluid device attachment 210 such that, when properly used, the height direction 232 is oriented at least substantially parallel to the direction of gravity and / or, within a suitable inclination range, obliquely to the direction of gravity.

[0165] For example, the housing 214 has a base 242. Conveniently, the base 242 is formed on an underside of the hot fluid device attachment 210, wherein the underside is formed at the bottom of the hot fluid device attachment 210 with respect to the vertical direction 232. Conveniently, the base 242 is at least substantially planar and extends in a geometric plane that runs at least approximately parallel to the longitudinal direction 234 and the transverse direction 236.

[0166] A hot fluid guide, designated as a whole by 252, is formed in the hot fluid device attachment 210.

[0167] The hot fluid guide 252 is designed to guide the hot fluid, for example from an inlet 256 of the hot fluid device attachment 210, to an outlet region 258 of the hot fluid device attachment 210, in particular along a guide contour 264 in a guide direction 266.

[0168] In some inexpensive variants, the guide contour 264 has several branches, at least in sections.

[0169] In particular, in the hot fluid guide 252, the hot fluid is guided along the guide contour 264 through a guide space designated as a whole by 268. The guide space 268 is advantageously a spatial area that comprises several, in particular connected, spatial sections. The hot fluid guide 252 is shown enlarged in Fig. 8 as an example.

[0170] Advantageously, the hot fluid device attachment 210 comprises a separating device designated as a whole by 272.

[0171] In particular, the separation device 272 is designed to at least partially separate liquid components from the hot fluid, which is guided in particular through the hot fluid guide 252.

[0172] Advantageously, the separation device 272 comprises a plurality of separation elements.

[0173] Conveniently, a guide device 274 is provided, which at least co-forms the hot fluid guide 252. Conveniently, the guide device 274 comprises a plurality of guide elements.

[0174] Preferably, the separation device 272 and the guide device 274 comprise at least partially the same elements.

[0175] For example, the guide device 274 is at least partially formed by the separation device 272. Advantageously, the separation device 272 is at least partially formed by the guide device 274.

[0176] Advantageously, the hot fluid guide 252 is configured to be angled, at least in sections. Advantageously, liquid components in a hot fluid guided through the hot fluid guide 252 are at least partially separated by the angled configuration, so that, in particular, the hot fluid guide 252 is also part of the separation device 272, at least to this extent. In particular, in a section of the hot fluid guide 252 with an angled configuration, the orientation of the guide direction 266 along the guide contour 264 changes.

[0177] In particular, a receptacle 282 for the hot fluid supply device 122 is formed at the inlet 256. In particular, the receptacle 282 is designed to at least partially accommodate the supply unit 134, in particular to accommodate its dispensing element 148.

[0178] Preferably, the receptacle 282 comprises a receiving chamber 284 for the outlet nozzle 154 of the feed unit 134. In particular, the guide space 268 adjoins the receiving chamber 284, and the guide contour 264 extends from the receiving chamber 284 through the guide space 268.

[0179] In particular, at least one impact plate 312 is arranged in the hot fluid guide 252.

[0180] Advantageously, the hot fluid is guided along the guide contour 264 onto an impact surface 313 of the impact plate 312.

[0181] Preferably, the hot fluid guided along the guide contour 264 in the guide direction 266 is guided at least approximately perpendicularly to the impact surface 313.

[0182] Advantageously, the impact plate 312 is arranged in a section of the guide space 268 adjoining the receiving chamber 284 and is advantageously aligned such that hot fluid supplied by the hot fluid supply device 122, which in particular exits from the outlet nozzle 154, for example in a straight line, is guided onto the impact plate 312.

[0183] In particular, the impact plate 312 extends at least substantially in a geometric plate plane 314 and / or advantageously the impact surface 313 extends at least approximately parallel to the geometric plate plane 314.

[0184] For example, the impact plate 312 is held on a web portion 316 of the guide device 274 at a portion forming the receiving chamber 284. Advantageously, the web portion 316 is narrow in order to impede the flow of the hot fluid as little as possible.

[0185] Conveniently, at least one guide surface 322, for example, of an element forming the impact plate 312, extends obliquely rearward from the impact plate 312. In this case, a rearward extension is related to a direction of the hot fluid impacting the impact plate 312 such that the at least one guide surface 322 extends away from the impact plate 312 on a side of the impact plate 313 that is opposite the side with the impact surface 313.

[0186] In particular, the impact surface 313 of the impact plate 312 and the guide surface 322 are formed on opposite sides of the geometric plate plane 314.

[0187] In particular, the guide surface 322 extends obliquely outwards from the impact plate 312, wherein outside refers, for example, to a view in the direction of the impacting hot fluid and in this viewing direction the guide surface extends laterally outwards from the separation plate 322.

[0188] For example, the element forming the impact plate 312 is frustoconical, with the impact plate 312 having its impact surface 313 positioned at the top surface of the truncated cone, and the lateral surface of the truncated cone forming the guide surface 322. The top surface of the truncated cone is smaller than the base surface of the truncated cone. Preferably, the guide space 268 extends far laterally from the impact plate 312, so that a free space is formed laterally from the impact plate 312, preferably in at least two approximately semicircular space sections. The hot fluid striking and deflected by the impact plate 312 can advantageously spread into the free space.

[0189] The free space area has a wide extent in particular if it extends from the impact plate 312 at least with a length which corresponds at least to the extent of the impact plate 312 and is preferably at least twice as long as the extent of the impact plate 312 in its lateral extent.

[0190] In particular, at the impact plate 312, a flow of the hot fluid is deflected by at least approximately 90°, since the hot fluid striking the impact plate 312 is deflected to the side.

[0191] In particular, the orientation of the guide direction 266 changes again by at least approximately 90° in the guide section located laterally of the impact plate 312. Conveniently, the guide contour 264 extends laterally away from the impact plate 312 and at least approximately parallel to the geometric plate plane 314, and then the guide contour is deflected to extend at least approximately perpendicular to the plate plane 314 and, in particular, to extend past the impact plate 312.

[0192] In particular, at least globally, the flow of the hot fluid is also deflected by at least approximately 90°, since the hot fluid flows at least globally along the guide contour 264. In more detail, the hot fluid can, for example, exhibit a laminar flow at least in sections and / or a turbulent flow at least in sections. Preferably, at least one filter 332 is arranged in the hot fluid guide 252, for example, as part of the separation device 272.

[0193] The filter 332 comprises a filter material with filter openings. For example, the filter openings extend transversely to a passage direction in the micrometer range, for example, between 1 lpm and 500 μm.

[0194] Preferably, the filter material is a hydrophobic material.

[0195] Advantageously, the guide contour 264 runs through the filter 332 and in particular through its filter material.

[0196] Conveniently, the filter 332 is arranged along the guide contour 264 following the impact plate 312.

[0197] Preferably, the filter 332 is arranged adjacent to the free space portion 324 formed at the impact plate 312.

[0198] For example, the filter material of the filter 332 is inserted into a part of the guide device 274 and preferably attached thereto.

[0199] It is particularly advantageous if a support structure 336 secures at least the filter material of the filter 332, and in particular at least substantially the entire filter 332, against a change in position at least in one direction. In particular, the filter 332 is supported at least partially, for example, at least its filter material is partially supported, on the support structure 336.

[0200] Preferably, the support structure 336 is arranged at least partially adjacent to an outlet side 338 of the filter 332, wherein a hot fluid flowing through the filter 332 exits the filter 332, in particular from its filter material, at the outlet side 338. In particular, the outlet side 338 is the side of the filter 332 at which the guide contour 264 extends out of the filter 332, in particular from its filter material.

[0201] In particular, the support structure 336 is formed from a part of the guide device 274 and / or the separation device 272.

[0202] Advantageously, at least one separation plate 342 is provided, in particular as part of the separation device 272 and / or as part of the guide device 274.

[0203] Advantageously, the separating plate 342 is arranged in the hot fluid guide 252 such that the separating plate 342 acts in a separating manner on a hot fluid flowing along the guide contour 264, for example, in a laminar and / or turbulent manner. Advantageously, the separating action of the separating plate 342 causes liquid components in the hot fluid to be at least partially separated from the hot fluid and, in particular, remain adhering to the separating plate 342 at least temporarily.

[0204] In particular, the separating plate 342 is arranged at an angle such that a flow of a hot fluid flowing in particular along the guide contour 264 is deflected at the separating plate 342 and is preferably deflected by an angle WU greater than 90°. In particular, the angle WU between the vectors of the flow direction and / or guide direction 266 along the guide contour 264 is measured, on the one hand, before the deflection and, on the other hand, after the deflection.

[0205] Advantageously, the separating plate 342 is arranged in such a way that one component 266K of the guide direction 266 and / or the flow direction of the hot fluid along the guide contour 264 after the deflection is oriented opposite to the guide direction 266 and / or the flow direction of the hot fluid before the deflection and the other component 266T of the direction after the deflection is oriented perpendicular to the guide direction 266 and / or the flow direction of the hot fluid along the guide contour 264 before the deflection.

[0206] In particular, the separation plate 342 is arranged obliquely oriented to the height direction 232.

[0207] In particular, the hot fluid rises at least substantially upwards along the direction of gravity and thus, with proper alignment of the hot fluid device attachment 210, upwards in the vertical direction 232 and / or obliquely thereto. Due to the obliquely oriented arrangement of the separator plate 342, this tendency of the hot fluid to rise upwards is at least partially impaired by the separator plate 342, and thus the hot fluid flowing, in particular, along the guide contour 264 is guided along the separator plate 342, and the separator plate 342 exerts at least a small flow resistance on the flow of the hot fluid.

[0208] In particular, after the section in which the guide contour 264 runs along the separation plate 342, a guide section is arranged which is angled, in which in particular the guide direction 266 changes its orientation and advantageously changes here at least approximately by at least 90° and preferably by more than 90°.

[0209] Conveniently, the guide contour 264 extends along the separation plate 342 to an end 346 of the separation plate and around the end 346 of the separation plate 342.

[0210] In particular, after the guide section along the separator plate 342, the flow of the hot fluid is deflected such that a component 266K of the guide direction 266 and / or the flow of the hot fluid is oriented opposite to the orientation of the guide direction 266 and / or the flow direction of the hot fluid along the separator plate 342, and a component 266T of the guide direction 266 and / or the flow direction of the hot fluid in the guide section after the separator plate 342 is oriented perpendicular to the orientation of the guide direction 266 and / or the flow direction of the hot fluid along the separator plate 342. In particular, this change in orientation occurs in the guide section that runs around the end 346 of the separator plate 342.In particular, an angle WU between the vector of the guide direction 266 and / or the flow direction along the separation plate 342 on the one hand and the vector of the guide direction 266 and / or the flow direction of the hot fluid in the guide section which is formed downstream of the separation plate 342 is greater than 90°.

[0211] For example, the support structure 336 extends between the filter 332 and the separation plate 342. For example, the support structure 336 is formed integrally with the separation plate 342.

[0212] In particular, the hot fluid device attachment 210 has an outlet section 352 with outlet openings 354. By way of example, only some of the plurality of outlet openings 354 are provided with a reference numeral in Figs. 3 and 4.

[0213] The outlet openings 354 lead to the outlet region 258, wherein the outlet region 258 is located outside the hot fluid device attachment 210 adjacent to the outlet section 352.

[0214] In particular, an outlet chamber 358 is formed on the inside of the hot fluid device attachment 210 adjacent to the outlet section 352, and the outlet openings 354 lead fluidically from the outlet chamber 358 to the outlet region 258. In particular, branches of the guide contour 264 each extend through a respective outlet opening 354.

[0215] The outlet section 352 is preferably formed from a metallic element, in particular. The element forming the outlet section 352 is advantageously arranged on at least one housing part 216 and advantageously connected thereto in a fluid-tight manner. In particular, an edge section 362 at least partially surrounds the outlet section 352 on its circumference. For example, the edge section 362 is designed to be closed on its circumference, surrounding the outlet section 352.

[0216] In particular, the term “circumferentially” is to be understood to mean that the design is circumferentially formed with respect to an axis, wherein the axis extends through one of the outlet openings 354 and its axial direction extends at least substantially parallel to the guide direction 266.

[0217] Advantageously, the edge portion 362 is formed by at least one housing part 216, wherein the outlet portion 352 and in particular the element forming the outlet portion 352 is arranged on the edge portion 362 on the housing part, in particular in a fluid-tight manner.

[0218] Preferably, the exit section 352 is recessed at least relative to an outwardly oriented surface of the edge section 362. In particular, the edge section 362 thus protrudes at least partially beyond the exit section 352 in the direction of the guide direction 266 oriented from the exit openings 354 to the exit region 258.

[0219] Advantageously, the outlet openings 354 are formed in an upper region of the outlet section 352 relative to the height direction 232. In particular, the upper region is located in an upper half of the outlet section 352 relative to the height direction 232 and, for example, in an upper third of the outlet section 352.

[0220] Preferably, a guide section of the hot fluid guide 252 formed directly in front of the outlet chamber 358 opens into an upper region of the outlet chamber 358 with respect to the height direction 232. In particular, the upper region of the outlet chamber 358 is located in an upper half of the outlet chamber 358 with respect to the height direction 232 and is located, for example, in an upper end region of the outlet chamber 358.

[0221] In particular, the guide section following the separation plate 342 opens into the outlet chamber 358. In particular, after being deflected around the separation plate 342, the hot fluid flows into the outlet chamber 358 and in particular into its upper region.

[0222] Preferably, the outlet openings 354 lead from the upper region of the outlet chamber 358 to the outlet region 258.

[0223] Preferably, the guide section, which is formed directly preceding the outlet chamber 358, opens into the outlet chamber 358 above the outlet openings 354 with respect to the height direction 232.

[0224] In particular, a cumulation chamber 368 is formed in a lower region of the outlet chamber 358 relative to the vertical direction 232. In particular, the cumulation chamber 368 comprises at least a lower third of the outlet chamber 358 relative to the vertical direction 232 and preferably at least the lower half of the outlet chamber 358.

[0225] In particular, the upper region of the outlet chamber 358 is located above the lower region and / or the accumulation space 368 of the outlet chamber 358 with respect to the height direction 232.

[0226] Advantageously, the guide section, which is formed directly preceding the outlet chamber 358, opens into the outlet chamber 358 above the accumulation space 368 with respect to the height direction 232. Preferably, the outlet openings 354 lead out of the outlet chamber 358 above the accumulation space 368 with respect to the height direction 232. In particular, the guide contour 264 runs through the outlet chamber 358 above the accumulation space 368 with respect to the height direction 232. Advantageously, the hot fluid device attachment 210 comprises at least one liquid collection device 412, in particular for collecting, for example, separated liquid components of the hot fluid guided through the hot fluid guide 252. Preferably, the liquid collection device 412 comprises at least one collection space 416 for receiving and collecting, in particular, separated liquid components of the hot fluid.

[0227] Conveniently, the liquid collecting device 412 comprises a collecting container 418, in the interior of which the at least one collecting space 416 is formed.

[0228] Advantageously, the collecting space 416 is fluidly connected to at least one section of the hot fluid guide 252 and / or to at least one area around at least one separation element of the separation device 272.

[0229] For example, the liquid collecting device 412 comprises at least one collecting channel 422, which opens into a section of the hot fluid guide 252 and into the collecting space 416.

[0230] Preferably, at least one collecting channel 422 opens into a spatial region in which a section of the hot fluid guide 252 runs between the filter 332 and the separation plate 342.

[0231] Preferably, the collecting channel 422 opens into a lower region relative to the height direction 232 and in particular into a lowest region of the spatial region with the guide section.

[0232] Conveniently, at least one valve unit 424 is arranged in the collecting channel 422, wherein the valve unit 424 at least impedes, and preferably at least substantially prevents, the flow of a fluid through the collecting channel 422 in the direction out of the collecting chamber 416, for example, toward the spatial region with the guide section. For example, the valve unit 424 is designed at least in the manner of a check valve.

[0234] Preferably, at least one venting channel 442 is provided in the liquid collecting device 412, which opens into the collecting space 416.

[0235] In particular, the vent channel 442 is a separate channel from the collection channel 422.

[0236] Advantageously, the venting channel 442 opens into at least an upper region of the collecting space 416 with respect to the height direction 232, and in particular, the venting channel 442 opens into the collecting space 416 at an upper side with respect to the height direction 232.

[0238] Preferably, the liquid collection device 412 comprises at least one display unit 452 for at least partially displaying a fill level of a liquid in the collection space 416.

[0239] For example, the liquid collecting device 412 comprises two display units 4521 and 452II, wherein the two display units 4521,11 are advantageously formed on opposite lateral sides of the hot fluid device attachment 210 with respect to the transverse direction 236.

[0240] By way of example, two display units 4521,11 are shown in Figs. 3 and 4, which are essentially of the same design, with differently designed display units 452 being provided in variants.

[0241] Advantageously, the housing 214 and in particular a housing part 216 in the region of the display unit 452 is designed such that at least part of the collecting space 416 can be seen from the surroundings of the hot fluid device attachment 210 and at least part of the fill level of a liquid can be directly recognized there.

[0242] For example, in some variants, a housing part 216 is transparent and / or translucent in the area of ​​a display unit 452. For example, in some variants, the housing 214 has a recess in the area of ​​a display unit 452 through which the collecting chamber 416 is at least partially visible.

[0243] In particular, the display unit 452 can at least detect whether a fill level of a liquid in the collection chamber 416 is greater or less than a tolerable threshold value of the fill level.

[0244] Preferably, the hot fluid guide 252 is arranged in the housing interior 218 at least largely spaced from the outer wall of the housing 214 formed by the outer wall sections 224. In particular, a technically-related exception to the largely spaced arrangement is that the hot fluid guide 252 leads from the housing interior 218 to the outlet region 258 and into the vicinity of the hot fluid device attachment 210, and thus a spaced configuration is not possible there. In particular, a spaced configuration is therefore not possible at the outlet section 352. In particular, an intermediate space 462 is formed between the hot fluid guide 252 and in particular the guide device 274 and / or separation device 272 on the one hand, and the outer wall of the housing 214 on the other.

[0245] Advantageously, the intermediate space 462 is formed at least in sections between a part delimiting the guide space 268 of the hot fluid guide 252 and an outer wall section 224.

[0247] Advantageously, the guide chamber 268 of the hot fluid guide 252 and / or the collection chamber 416 is separated from the surroundings of the hot fluid device attachment 210 by a double wall.

In particular, the at least two wall sections comprise at least one outer wall section 224 of the housing 214 and a wall section delimiting the guide chamber 268 and / or the collection chamber 416, wherein these two wall sections are different wall sections.

[0249] In particular, an exception to the double-walled design is provided for technical reasons at the inlet 256, where the receptacle 282 for the hot fluid supply device 122 is formed. There, for example, a double-walled design is not possible along a direct connecting line if this line runs through the receptacle 282, since the receptacle 282 typically has to be open to the surroundings of the hot fluid device attachment 210. In particular, a double-walled design is not technically possible at the outlet region 258; instead, in particular, only the outlet section 352 is formed, which separates the inward outlet chamber 358 from the outlet region 258 located outside the housing 214.

[0250] Advantageously, a plurality of spacers 464 are provided which hold the guide device 274 and / or the separation device 272 in the housing interior 218 at a distance from the outer wall sections 224.

[0251] In some preferred variants, at least some spacers 464 are formed from parts of the guide device 274, as shown by way of example in Figs. 5 to 7. In some favorable variants, at least some spacers 464 are formed from housing parts 216, wherein, for example, the arrangement of the spacers 464, at least with regard to the basic function of spaced-apart holding, is arranged analogously to the spacers 464 shown by way of example in Figs. 5 to 7, so that these representations are also representative of such variants.

[0252] It is particularly advantageous if the guide device 274 and / or the separation device 272 and / or the liquid collection device 412 are designed as a device insert 472 and in particular are designed as a coherent insert assembly.

[0253] As an example, a device insert 472 is shown separately in Figs. 9 and 10.

[0254] Conveniently, the device insert 472 is arranged in the housing interior 218 in an assembled state of the hot fluid device attachment 210, as shown by way of example in Figs. 2 to 8.

[0255] In particular, the device insert 472 can be inserted into the housing 214 formed by the housing parts 216 and / or the housing parts can be mounted around the device insert 472 to form the housing 214. In particular, the housing parts 216 can be firmly connected to the device insert 472, in particular at least via the spacers 464, and in particular are fastened to one another.

[0256] In particular, preferred embodiments and their favorable function and, for example, advantages thereof are briefly summarized as follows.

[0257] The hot fluid device attachment 210 comprises in particular an inlet 256, for example with a receptacle 282 for a hot fluid supply device 122, wherein a hot fluid can be supplied at the inlet 256.

[0258] In particular, the hot fluid comprises water. The temperature of the hot fluid is advantageously at least 60° Celsius, in particular at least 80° Celsius, and advantageously at least 95° Celsius.

[0259] In particular, the hot fluid is a fluid mixture with, in particular, gaseous and liquid components. For example, the hot fluid is a two-phase fluid mixture. In particular, the liquid components include water, for example, water droplets. In particular, the gaseous components include water vapor.

[0260] A hot fluid guide 252 is provided to guide a hot fluid, for example a hot fluid supplied at the inlet 256, to an outlet region 258.

[0261] In the outlet region 258, the hot fluid can be applied, for example, to a garment, in particular a shirt or the like, in particular for smoothing the garment and, for example, in some variants for at least partial cleaning.

[0262] In particular, it is intended to apply steam during use, so that hot fluid comprising primarily steam should advantageously reach the outlet region 258. Advantageously, the proportion of liquid components in the hot fluid is at least reduced along the hot fluid guide 252, so that a hot fluid with at most a small proportion of liquid components advantageously reaches the outlet region 258.

[0263] In order to reduce the proportion of liquid components in the hot fluid, the hot fluid guide 252 is designed to be angled at least in sections and / or a separation device 272 is formed therein.

[0264] In particular, an impact plate 312 is provided, which is advantageously arranged in a guide section adjoining the inlet 256.

[0265] Advantageously, the impact plate 312 is arranged such that the hot fluid being introduced strikes the impact plate 312 at least substantially directly. Advantageously, the velocity of at least liquid components of the hot fluid is reduced by the impact. Advantageously, the impact separates and / or at least partially atomizes and / or preferably at least partially evaporates liquid components from the hot fluid.

[0266] Advantageously, large, open spaces are formed laterally of the impact plate 312. In particular, this allows gaseous components of the hot fluid to be effectively guided around the impact plate 312. In particular, the open spaces provide space for rebounding liquid components, allowing them to atomize and / or at least partially evaporate.

[0267] Preferably, at least one filter 332 is provided. Advantageously, liquid components of a hot fluid are at least partially separated from the hot fluid as they flow through the particularly close-meshed filter material of the filter 332. Advantageously, the filter material is hydrophobic, so that liquid components separated from the hot fluid accumulate at least less in the filter material and at least largely flow out of the filter material.

[0268] Advantageously, at least one separation plate 342 is provided.

[0269] In particular, the separation plate 342 is designed and arranged such that at least partially liquid components are separated from the hot fluid flowing along the separation plate 342 on the separation plate.

[0270] In particular, an exit section 352 with exit openings 354 is provided, wherein the exit openings 354 lead to the exit region 258.

[0271] In particular, an outlet chamber 358 is formed inside the outlet section 352. The outlet openings 354 lead from the outlet chamber 358 to the outer outlet region 258.

[0272] Preferably, the hot fluid is guided through an upper region of the outlet chamber 358. In particular, a guide section of the hot fluid guide 252 opens into the upper region. In particular, the outlet openings 354 open into the upper region of the outlet chamber 358.

[0273] Advantageously, a proportion of liquid components in the hot fluid is reduced in this way, since the liquid components are heavier and sink downwards from the upper region of the outlet chamber, for example into a cumulation space 368 of the outlet chamber 358, and do not reach the outlet region 258.

[0274] In particular, a liquid collection device 412 with at least one collection chamber 416 is provided. In particular, liquid components separated from the hot fluid can thus be collected in the collection chamber 416. In particular, a collection channel 422 leads from at least one guide section of the hot fluid guide 252 and / or from at least one region located around a separation element to the collection chamber 416. In particular, the collection channel 422 opens into a spatial region in which the filter 332 and / or the separation plate 342 are arranged at least adjacent thereto, so that liquid components separated at these separation elements can advantageously be discharged from the spatial region through the collection channel 422.

[0275] The liquid collection device 412 preferably comprises at least one display unit 452, through which a user can at least partially determine the fill level of a liquid in the collection chamber 416. Advantageously, this allows a user to recognize when it is necessary to empty the collection chamber 416, for example, through a drain 432.

[0276] In particular, at least one venting channel 442 leads out of the collecting chamber 416. The venting channel 442 preferably opens into the collecting chamber 416 at least in an upper region and, in particular, on an upper side. Advantageously, a fluid, in particular a gaseous fluid, can thus escape from the collecting chamber 416 through the venting channel 442 when liquid components are supplied into the collecting chamber 416 through the collecting channel 422.

[0277] It is particularly advantageous if the venting channel 442 opens into a guide section of the hot fluid guide 252, so that gaseous components of the hot fluid escaping from the collecting chamber 416 are advantageously guided back into the hot fluid guide 252. For example, the venting channel 442 opens into the outlet chamber 358 and there, preferably, into an upper region thereof.

[0278] For example, a valve unit 424 is arranged in the collecting channel 422, which at least impedes the flow of, in particular, liquid components from the collecting chamber 416 through the collecting channel 422. Advantageously, this at least reduces the risk of liquid components accumulated in the collecting chamber 416 flowing back into the hot fluid guide 252. Preferably, the valve unit 424 is designed such that the flow of a fluid through the collecting channel into the collecting chamber 416 can occur as unhindered as possible.

[0279] Preferably, the hot fluid guide 252 is arranged in the housing interior 218 at least substantially spaced from an outer wall of the housing 214 of the hot fluid device attachment 210.

[0280] Preferably, a guide space 268 for the hot fluid of the hot fluid guide 252 is at least largely double-walled and separated from the surroundings of the hot fluid device attachment 210.

[0281] Preferably, the collecting chamber 416 is at least largely separated from the surroundings of the hot fluid device attachment 210 by a double wall. For example, the collecting chamber 416 is formed in the interior of a collecting container 418, wherein the collecting container 418 is arranged in the housing interior 218.

[0282] Advantageously, gaps 462 are formed between parts defining the guide space 268 and / or the collecting space 416 on the one hand and outer wall sections 224 on the other hand.

[0283] Advantageously, heat transfer from the hot fluid guide 252 and / or from the collection chamber 416 to the outer wall of the housing 214 is at least reduced, so that the outer wall of the housing 214 is heated at least less intensely and preferably at most slightly by the hot fluid flowing through it and / or the liquid components collected in the collection chamber 416. This advantageously increases the safety of a user when using the hot fluid device attachment 210, since the outer wall of the housing 214 heats up less intensely, thus reducing the associated risk. Advantageously, a guide device 274 at least partially forming the hot fluid guide 252 and / or a separating device 272 are held at a distance from outer wall sections 224 in the housing interior 218 by spacers 464.

[0284] Preferably, the guide device 274 and / or the separation device 272 and / or the liquid collection device 412 are formed at least largely by a device insert 472. In particular, the device insert 472 forms a coherent assembly.

[0285] In particular, this provides a constructively favorable solution for the formation of the hot fluid guide 252.

[0286] Advantageously, the device insert 472 enables a structurally simple solution for the spaced arrangement in the housing interior 218 of the guide device 274 and / or the separation device 272 and / or the liquid collection device 412.

[0287] In particular, the collecting container 418 and / or the parts delimiting the guide space 268 and / or the separating elements of the

[0288] Separation device 272, in particular the impact plate 312 and / or the filter 332 and / or the separation plate 342, and for example the vent channel 442 are part of the device insert 472.
