Description

[0001] The present invention relates to a fan attachment for a device for room temperature control and / or room ventilation, in particular a fan heater, according to the features in the preamble of claim 1. Furthermore, the present invention relates to a device for room temperature control and / or room ventilation, in particular a fan heater, having the features of claim 12 and to a temperature control and / or ventilation system with such a device according to the features of claim 15.

[0002] Room temperature control and / or ventilation devices are typically installed in rooms where they serve to temporarily circulate air and / or influence the air temperature. In addition to pure circulation, they can also have a connection for the supply of fresh air and / or the removal of exhaust air. Temperature control allows the targeted heating and / or cooling of the room air by generating a correspondingly warm or cool air flow. Such devices have a housing with at least one air inlet designed to draw in ambient air, such as room air and / or fresh air. This air inlet is in fluid communication with an air outlet of the housing. A fan arranged between the air inlet and air outlet within the housing ensures the necessary air flow.Temperature control is achieved via a temperature control unit, usually located upstream or downstream of the fan in the housing. Depending on the design, this temperature control unit also allows for air humidity to be influenced, for example in the form of a humidifier. Alternative designs such as dehumidifiers are used, among other things, for drying rooms and entire buildings. These devices, also commonly known as air conditioners, can of course also combine some or all of the aforementioned features. Devices that are particularly mobile and – despite their compact dimensions – equipped with the appropriate performance are often used on construction sites or at events in connection with room temperature control and / or room ventilation; for example, in the form of mobile fan heaters or the previously mentioned humidifiers, dehumidifiers, or air conditioners.

[0003] In order to prevent access to rotating and / or sometimes extremely hot parts inside the enclosure due to safety regulations, both the air inlet and the air outlet are covered. In the simplest form, this can be achieved, for example, by strips spanning the respective outlet, perforated sheets, or a suitable mesh structure. A corresponding design with strips arranged parallel to each other is described in KR 10 178 26 30 B1.

[0004] DE 20 2011 050 155 U1 discloses a device for room air filtration, comprising a housing with a fan and at least one air inlet and an air outlet fluidly connected to the air inlet. Furthermore, a fan attachment is provided, which is detachably attached to the housing, forming a fluidly conductive connection between its passage and the air outlet.

[0005] DE 203 01 652 U1 discloses a device for room temperature control and / or room ventilation, comprising a housing with at least one air inlet and an air outlet connected to the air inlet by a fluid connection. A fan is arranged within the housing between the air inlet and the air outlet. In this configuration, the device is designed for universal use as a compact and mobile ventilation unit in non-stationary ventilation systems with pipes or hoses.

[0006] DE 20 2011 106 891 U1 discloses a ventilation insert suitable for installation in the outer walls of a filter system housing. The ventilation insert consists of a holder with two holder sections, between which individual slats extend, forming a permeable area.

[0007] JP 2014-134367 A is directed to a ventilation device intended for permanent installation behind a false ceiling of a room. This device serves to exhaust room air and introduce outside air. A heat exchanger equipped with fans ensures at least a partial transfer of the temperature of the exhausted room air to the outside air being introduced. Furthermore, a filter box located in an adjacent room is provided.

[0008] Alternatively, it is known to equip the air outlet with a fan attachment, which allows the connection of a separate air distributor. In this context, EP 2 789 926 A1 discloses a device for room temperature control and / or room ventilation, the fan attachment of which, attached to the device via its base, has a passage connected to the air outlet in a fluid-conducting manner. In the area of ​​the passage extending between a first base side and a second base side of the base, an adapter designed for coupling to a separate air distributor is provided, which adapter is arranged on the first base side for this purpose.

[0009] The air distributor has several radially arranged outlet openings at its free end. Particularly when the air outlet is arranged vertically at the top of the device, the then essentially vertical alignment of the attached air distributor enables the air flowing through the device to be discharged well above the device. In this way, a large throw distance with a corresponding radius around the device can be achieved. Because the discharge occurs more or less overhead, direct exposure to the air flow is largely avoided, which makes staying in the area around the device more comfortable, for example. Objects located in the immediate vicinity of the device are also avoided from direct air flow, which prevents unwanted blowing away of light objects such as paper.

[0010] However, not all rooms and applications are suitable for air distribution at the level structurally defined by the air distributor. For example, ceiling constructions or built-in features may require a low room height, meaning the location of the device is subject to corresponding compromises or may not be possible at all. Sometimes, a more direct distribution of, for example, heated air into the area occupied by a person is desired in order to create a comfortable atmosphere in the area around the device as quickly as possible. Large rooms and / or high ceilings may also require the air to be distributed as directly as possible into the area occupied by people in order to achieve adequate temperature control. In view of these observations, the usability of the devices known to date is indeed limited, meaning that there is still room for improvement.

[0011] Against this background, the object of the present invention is to further develop a fan attachment and a device equipped therewith for room temperature control and / or room ventilation in such a way that, despite an economical method of production, they have a more flexible use while at the same time being highly practical and user-friendly.

[0012] The solution to this problem, according to the invention, consists in a fan attachment having the features of claim 1 and in a device for room temperature control and / or room ventilation according to the features of claim 12. Furthermore, a temperature control and / or ventilation system with such a device according to the features of claim 15 is presented. Advantageous further developments are the subject of the respective dependent claims 2 to 11 as well as 13 and 14.

[0013] It should first be noted at this point that the features listed individually in the following description can, of course, be combined with one another in any technically reasonable manner, thus demonstrating further embodiments of the invention. Furthermore, the invention is not limited to the aforementioned embodiments and exemplary contents, so that further embodiments of the basic idea of ​​the invention are also to be considered part of it.

[0014] For the sake of simplicity, a device for room temperature control and / or room ventilation will be discussed below, which, within the scope of the invention presented here, can of course also be suitable for serving as an air humidifier, air dehumidifier or generally as an air conditioner, so that the chosen terminology does not result in any functional restriction to pure temperature control and / or ventilation, but can also include the aforementioned properties.

[0015] The core idea of ​​the fan attachment according to the invention is that its base can be coupled to the device either via its first base side or via its second base side. This can preferably be achieved in the form of a correspondingly reversible design of the fan attachment. The optional arrangement of the fan attachment makes it possible for either its adapter arranged on the first base side to be available for coupling to a separate air distributor or for its second base side to be usable. Here, the invention provides that a distributor hood is arranged on the said second base side, at least in some areas, extending over the passage. The distributor hood serves to directly discharge the air flowing out of the device into the environment.In other words, the fan attachment now combines at least two independently usable functions, in that it can be used either for direct air distribution via the distributor hood or for indirect air distribution by forwarding it to an air distributor that can be coupled to the adapter or, for example, an air duct that can be coupled to it.

[0016] The resulting advantage lies in the significantly more flexible use of the fan attachment. Particularly as a component of a preferably mobile or stationary device for room temperature control and / or room ventilation, it is always present anyway, so that a decision need only be made on site as to which of its air extraction options is more suitable for the current application - for example, purely thematically - taking into account the respective room. The reversible design of the fan attachment, for example, makes it economically viable to manufacture overall. Furthermore, there is no longer any need to keep different devices on hand to correspond to the possible applications of the fan attachment according to the invention. The extremely easy realignment of the fan attachment relative to the device, preferably by simply turning it, demonstrates a high level of user-friendliness in practice.Any existing devices can also be easily retrofitted with the fan attachment according to the invention in order to make their usability more flexible.

[0017] According to a further development of the basic inventive concept, the distributor hood of the fan attachment can have at least two side walls. The distributor hood can preferably have four side walls, two of which are arranged opposite each other, for example, parallel to each other. Furthermore, the four side walls can each preferably have the same length and height, so that, when they extend at right angles to each other, an overall square configuration for the distributor hood results. Of course, various other designs for the distributor hood are also conceivable, such as with a single circularly curved and thus continuous wall or a dome shape.When two side walls are arranged, they can, for example, either be parallel to each other or form an angle of less than 90° between them, while their ends are either generally spaced apart or touch each other at one end. When three side walls are arranged, they can, for example, form a triangular shape between them.

[0018] In any case, at least one exhaust opening is arranged and / or formed on at least one of these side walls. "Arranged" here means, for example, a connection to a part forming an exhaust opening, such as a pipe section. The design of said exhaust opening in this context is understood to mean, for example, a through-opening penetrating the associated side wall. Each side wall can preferably have at least one such exhaust opening. Air flowing from the at least one exhaust opening can ultimately escape into the environment via the passage provided in the base of the fan attachment from the device into the distributor hood. The direction and size of the escaping air flow can be specifically adjusted via the position and / or shape of the at least one exhaust opening.

[0019] In this context, the invention provides that a slat can be provided in the region of the at least one exhaust opening. Said slat represents a strip or lip, for example, inclined or inclinable relative to the plane of the exhaust opening, which primarily serves to change the direction of the air flow impinging on it. In this case, the slat can also be designed to be movable about a pivot axis, for example, which enables a corresponding change in its respective orientation. This makes it possible, for example, to completely close the exhaust opening with the associated slat. The quantity and / or direction of the air flowing out of the exhaust opening can also be adjusted in this way. Advantageously, the slat and the associated side wall can enclose an angle between them, which can also be changed depending on the design of the slat.

[0020] According to the invention, the at least one slat can preferably be a single-piece component of the associated side wall made of the same material. This can be achieved, for example, by forming the slat out from the plane of the side wall, which can be interrupted along a dividing line before or during production of the slat. A slat located on an edge or border of the side wall, on the other hand, can be produced without such a separation, for example by bending and / or stretching the material. Particularly preferably, the at least one slat can be located within the edges or borders of the associated side wall.The dividing line can be in the form of a straight line, for example, running parallel to a horizontal edge or margin of the side wall, with the regions of the side wall located at both ends being curved, while the section of the side wall extending between these curves is bent out of the plane of the side wall around a bending line running parallel to the dividing line. The edges of the dividing line, which were still directly adjacent to one another before the forming process, are thus correspondingly spaced apart, forming the blow-out opening.

[0021] A further development of the fan attachment according to the invention provides that its distributor hood can have a cover located above the passage. The cover can, for example, be rectangular or square. Furthermore, the cover is spaced from the passage of the base by incorporating the side walls extending between it and the base. The cover can thus serve as a baffle to redirect an air flow hitting it through the passage to the at least one exhaust opening located in at least one side wall. The resulting overpressure within the distributor hood advantageously increases the speed of the air flowing out through the at least one exhaust opening.

[0022] With a view to the at least twofold usability of the fan attachment according to the invention, the at least one slat can extend with its free end into an interior space of the distributor hood. The interior space can in particular be delimited circumferentially by, for example, a total of four side walls. Said orientation of the at least one slat has the advantage, particularly when using the adapter, that the air flow hitting the fan attachment via the device's air outlet is directed specifically into the interior space of the distributor hood. If a cover is provided, a fluid-conducting connection to the passage of the base is only created via the at least one exhaust opening. Preferably, the slat can be aligned such that the air flow flowing from the outside into the interior space of the distributor hood via the exhaust opening is directed directly to the passage.If the distribution hood is used, the airflow entering the interior via the passage can be directed diagonally upwards out of at least one outlet opening. This orientation allows for convenient access to the device without feeling a direct draft.

[0023] Preferably, at least one of the side walls of the distributor hood can be recessed relative to a corresponding edge of the base, forming an edge strip. Depending on the width of this edge strip, this creates a storage area, which can serve as a kind of table replacement, particularly when approaching a device equipped with the fan attachment according to the invention.

[0024] To ensure the simplest, most economical, and always easy-to-handle design of the fan attachment, the invention provides for its base to be plate-shaped. This can be, for example, a rectangular or square sheet metal. Its dimensions can advantageously be adapted to the housing or the air outlet of a device equipped with it. The passage can, for example, be arranged centrally in the base in the form of a through-opening, such as through a corresponding hole or punched-out section.

[0025] Basically, it is envisaged that the adapter can have a collar which projects beyond the first base side to form an extension of the same which is connected to the passage in a fluid-conducting manner. The collar can accommodate the cross-sectional shape of the passage. For example, the collar can be annular. A specific embodiment can provide for this purpose, for example, a pipe section which is arranged in or in the region of the passage. Said pipe section can have a ring at its end which projects radially outwards and which, when the adapter is inserted into the passage, can serve to preferably permanently connect the adapter to the base, for example by means of gluing and / or welding. Angular shapes for the adapter collar are also conceivable, such as a triangle or square, to name just a few.

[0026] With regard to the arrangement of a collar, it is considered advantageous if it has at least one bead that projects radially outwards relative to the collar. Alternatively, the bead can also be recessed radially inwards. The bead improves the holding forces required to couple an air distributor to the adapter. For example, a ring that surrounds a section of the air distributor placed on the adapter from the outside can be arranged in such a way that it presses the part of the section located in front of the bead in the direction of load against the collar. In the case of a recessed bead, said ring can also be arranged in such a way that it presses part of the section of the air distributor into the bead.

[0027] The fan attachment according to the invention now presented is highly practical and user-friendly when combined with a device for room temperature control and / or room ventilation, such as a fan heater. Its at least twofold usability—directly discharging the air flowing through the device via its distributor hood or directing it into an air distributor that can be coupled with its adapter—offers extremely flexible use at the respective location. For example, by simply turning the fan attachment, either one of its functions (direct discharging) or the other function (directing it into an air distributor) can be used without the need for an additional device or other additional arrangements.The inventive design of the fan attachment, with a base preferably made of a sheet metal plate with a passage, as well as the distributor hood, also made of sheet metal, for example, in the area of ​​the passage, and the adapter in the form of a pipe section, also made of sheet metal, offers an overall economical manufacturing method. Alternatively, the fan attachment can of course also be made partially or entirely of plastic without compromising its advantageous functionality and usability.

[0028] The invention is further directed to a preferably movable or stationary device for room temperature control and / or room ventilation, which may, for example, be a fan heater. Said device comprises a housing with at least one air inlet and an air outlet fluidically connected to the air inlet. At least one fan is arranged between the at least one air inlet and the air outlet. Preferably, at least one temperature control unit can also be arranged upstream or downstream of the fan. The temperature control unit can, for example, be a cooling element and / or a heating element. Furthermore, a fan attachment according to the invention, as already indicated above, is provided, which is detachably attached to the housing, forming a fluid-conducting connection between its passage and the air outlet of the device.

[0029] The resulting advantages have already been explained in more detail in connection with the fan attachment according to the invention, so that in order to avoid repetition, reference is made here to the corresponding explanations.

[0030] According to a particularly preferred development of the device according to the invention for room temperature control and / or room ventilation, the housing can be designed in the area of ​​its air outlet for at least partially arranging either the adapter or the distributor hood of the fan attachment therein. Depending on the optional, in particular reversible, arrangement of the fan attachment in the area of ​​the air outlet on the housing, either its adapter or its distributor hood can extend at least partially into the housing. This results in an extremely aesthetic impression, since the functionality of the device is always visually limited to its current use. For example, two identical devices, each with a differently attached fan attachment, appear different from one another, even though both offer the same variety in terms of the possibility of emitting an air flow.The reason for this is the somewhat hidden arrangement of the unused part, in the form of the adapter or the fan attachment's distributor cover, within the case. At the same time, the communication between the adapter and the distributor cover via the base's passage ensures that a fluid-conducting connection is already established between the part of the fan attachment located outside the case and the device's air outlet via the part located inside the case. Complex handling to establish the connection is completely eliminated, as this connection is always established automatically when the fan attachment is placed on the case, regardless of its orientation.

[0031] The invention provides the simplest possible change in the use of the fan attachment, in that it can be detached from and reattached to the device's housing using only simple measures. For this purpose, the base can preferably be releasably attached to the device by at least one manually operable connecting means. Such a connecting means can be, purely by way of example, a snap fastener, a rotary knob, a wing screw, or any design with corresponding undercuts or plug-in tabs, as well as combinations of the above. Alternatively or additionally, the base can be releasably attached to the device by at least one connecting means that can be manipulated using a tool.This can also be purely an example of a connecting means having a contour that can be connected to the contour of a corresponding tool, such as Phillips, slotted, Allen, multi-tooth or hexagon screws, to name just a few possible designs.

[0032] Finally, the invention is also directed to a temperature control and / or ventilation system comprising a device according to the invention for room temperature control and / or room ventilation as previously outlined, as well as an air distributor through which air can flow. Preferably, said air distributor can be a fabric air distributor formed at least partially from a fabric, which only acquires its actual shape through inflation when air is flowing through it and at least partially collapses when not flowing through it. This results in extremely small dimensions for the air distributor when not in use, so that it can be easily carried along or stored at a suitable location in or on the device. Of course, the air distributor can also be formed, at least in part, from a more rigid material, such as sheet metal and / or plastic.In any case, the air distributor has an inlet opening and at least one outlet opening, wherein the inlet opening is designed for detachable attachment to the adapter of the fan attachment.

[0033] The resulting advantages have also already been explained in more detail in connection with the fan attachment according to the invention, so that in order to avoid repetition, reference is also made here to the corresponding explanations.

[0034] The invention is explained in more detail below using an exemplary embodiment schematically illustrated in the figures, from which further advantageous details and effects emerge. They show: Fig. 1 a fan attachment according to the invention with a view of its first base side in a first perspective view, Fig. 2 Remove the fan attachment Fig. 1 with a view of its second base side in a second perspective view, Fig. 3 a vertical section through the fan attachment Fig. 1 and Fig. 2 also in perspective view, Fig. 4 a movable device according to the invention for room temperature control and / or room ventilation with a fan attachment according to the invention in a perspective view, Fig. 5 turn off the device Fig. 4 with reversed fan attachment in a perspective view, Fig. 6 a first vertical section through the device Fig. 4 in one view and Fig. 7 a second vertical section through the device Fig. 5 in one view.

[0035] Fig. 1 shows a fan attachment 1 according to the invention in a perspective view. The fan attachment 1 comprises a base 2, which is here purely exemplary in the form of a plate. The plate 2 has a square shape, with its two opposite edges 3a, 3c extending parallel to a longitudinal direction X, while its two other opposite edges 3c, 3d extending parallel to a transverse direction Y running at right angles to the longitudinal direction X. Furthermore, the plate 2, in the embodiment shown purely exemplary, has two base sides facing away from one another in the form of a first base side 2a and a second base side 2b, which run parallel to one another due to the plate-shaped design of the base 2. Due to the representation in Fig. 1, the view falls on the first base side 2a, which points upwards with respect to a vertical direction Z. In the area of ​​the four outer corners of the base 2, a through hole L is arranged, which extends through the base 2. Said through holes L serve to fasten the fan attachment 1 to a device 100, which is not shown in detail here (see Fig. 4 to Fig. 7).

[0036] Located in the center of the plate 2 is a passage 4, which extends completely between the two base sides 2a, 2b of the base. In the area of ​​the passage 4, on the first base side 2a, an adapter 5 is arranged, which has an annular collar 6, which is shown here purely as an example. As a result, the collar 6 has the shape of a pipe section. The adapter 5 is designed such that its collar 6 protrudes from the first base side 2a, forming an extension of the latter that is connected to the passage 4 in a fluid-conducting manner. Approximately halfway up the collar 6 is a circumferential bead 6a, which, in the embodiment shown here purely as an example, protrudes radially outwards from the collar 6. The adapter 5 serves for the fluid-conducting coupling of the fan attachment 1 to an air distributor (not shown in detail here), which can preferably be a fabric air distributor.

[0037] The fan attachment 1 is designed to be reversible, so that it can be coupled to a device 100 for room temperature control and / or room ventilation via its first base side 2a or its second base side 2b (see Fig. 4 to Fig. 7). For this purpose, a distributor hood 7 is arranged on the second base side 2b facing away from the first base side 2a, which extends across the passage 4. Its structure will be explained in more detail later.

[0038] Fig. 2 is the fan attachment 1 from Fig. 1 after turning it over, so that the view essentially falls on its second base side 2b. The distributor hood 7, which can now be seen more clearly, has a total of four side walls 8a-8d, of which only the side walls 8a and 8b are visible in the present case, while the other two side walls 8c, 8d are covered by a cover 9 of the distributor hood 7. It can be seen that each of the four side walls 8a-8d recesses relative to the corresponding edge 3a-3d of the base 2, forming an edge strip 10a-10d. The cover 9 located above the passage 4 has a square shape adapted to the base 2, and is spaced from the passage 4 by incorporating the side walls 8a-8d extending between it and the base 2.

[0039] In the embodiment shown here purely as an example, four blow-out openings 11 are formed on each of the side walls 8c, 8d, the shape of which will be described in more detail below.

[0040] Fig. 3 shows a vertical section through the fan attachment 1. It can be seen that a slat 12 is provided in the area of ​​each exhaust opening 11. In this case, the slats 12 are each an integral component of the associated side wall 8a-8d, made of the same material. The side walls 8a-8d, together with the base 2 and the cover 9, enclose an interior space 13 between them, which is in fluid-conducting connection with the passage 4 and the exhaust openings 11. As can be seen, the slats 12 are bent into the interior space 13, so that their respective free end 12a extends into the interior space 13 and towards the passage 4. Due to their orientation, each slat 12 and the associated side wall 8a-8d enclose an angle α between them. In the present case, the angle α is purely exemplary between 40° and 50°.

[0041] Fig. 4 shows a device 100 according to the invention for room temperature control and / or room ventilation. In the present purely exemplary embodiment, this is a fan heater. The device 100 comprises a housing 101 with a lateral air inlet 102 and an air outlet 103 located at the upper end of the housing 101, over which the fan attachment 1 according to the invention, attached to the device 100, extends. In the orientation of the reversible fan attachment 1 shown here, its adapter 5 can be used to couple it to an air distributor (not shown in detail). The device 100, which has at least two rollers 104, is designed to be movable via these rollers and is therefore mobile. By omitting said rollers 104, the device 100 can also be used, for example, for stationary use.

[0042] Fig. 5 shows the device 100 from Fig. 4 with the fan attachment 1 rotated by 180°. This allows its distributor hood 7 to be used to discharge air flowing out of the device 100 directly into the environment via the exhaust openings 11.

[0043] Fig. 6 and Fig. 7 is a vertical section through the device 100 from Fig. 4 and Fig. 5, which illustrates its possible internal structure. The housing 101 comprises a fan 105 and a temperature control unit 106, which are arranged between the air inlet 102 and the air outlet 103 within the housing 101. As can be seen, the fan 105 is arranged in the area of ​​the air inlet 102, while the temperature control unit 106—designed here purely as an example as a heating element—is located in a region of the housing 101 between the fan 105 and the air outlet 103.

[0044] Fig. 6 shows the arrangement of the fan attachment 1 in the Fig. 4, in which the collar 6 of its adapter 5 is freely accessible from the outside, for example to be coupled to an air distributor (not shown in more detail). As can be seen, the interior of the housing 101 in the area of ​​its air outlet 103 is sufficiently large so that the distributor hood 7 is accommodated therein via the housing 101, which is otherwise open at the top in the form of the air outlet 103. In this way, the cover 9 of the fan attachment 1 faces the temperature control unit 106. The base 2 of the fan attachment 1 rests on the circumferential upper free edge of the housing 101. The fan attachment 1 is connected to the housing 101 via detachable connecting means which are guided through the through-holes L located on the base 2 and are otherwise not shown in more detail here.

[0045] As can be seen, a handle 107 is arranged at the upper end of the housing 101, which is positioned vertically above the rollers 104 and is spaced from the housing 101 by two arms 107a, 107b extending as an extension of the base 2 of the fan attachment 1. Opposite the rollers 104 in the horizontal direction, the housing 101 has a stand 108, so that the device 100 is supported on the one hand by its two rollers 104 and on the other hand by its stand 108 extending parallel to the rotation axes of the rollers 104. Purely by way of example, the stand 108 can be formed from a folded material such as sheet metal, as shown here. By appropriately manipulating the handle 107, the device 100 can be tilted in a manner not shown in detail, so that its stand 108 is raised while the rollers 104 continue to maintain contact with the respective surface.In this way, the device 100 is correspondingly movable and can be completely parked again via its stand 108 by removing its inclination at the respective location of use or storage.

[0046] During operation of the device 100, air sucked horizontally through the air inlet 102 into the housing 101 via the fan 105 is directed vertically upwards in the direction of the air outlet 103. The flowing air first passes through the temperature control unit 106 before hitting the cover 9 of the distributor hood 7 of the fan attachment 1. Via the annular gap running between the housing 101 and the distributor hood 7, the air flows through the exhaust openings 11 equipped with the louvers 12 in a virtually opposite direction to reach the interior 13 of the distributor hood 7. The inclination of the louvers 12 determines the further direction to be taken towards the adapter 5, through which the air ultimately reaches the environment, an air distributor (not shown in detail), or an air duct (likewise not shown in detail).

[0047] Fig. 7 shows the arrangement of the fan attachment 1 in its position turned by 180° on the housing 101, as already shown in Fig. 5. As can be seen, its distributor hood 7 extends completely out of the housing 101, while its adapter 5 is now arranged in place of the distributor hood 7 in the area of ​​the air outlet 103 within the housing 101.

[0048] During operation of the device 100, the air, which is sucked horizontally through the air inlet 102 into the housing 101 via the fan 105 and then directed vertically upwards via the temperature control unit 106 towards the air outlet 103, passes through the adapter 5 into the interior 13 of the distributor hood 7, where it initially at least partially impacts its cover 9. Due to the overpressure created within the distributor hood 7 by the inflowing air, the air ultimately passes through its outlet openings 11 into the environment, with the inclination of the slats 12 specifying a flow direction for the escaping air that is obliquely upwards in relation to the side walls 8a-8d of the distributor hood 7.

[0049] Turning between the Fig. 6 and Fig.The orientation of the fan attachment 1 shown in Figure 7 can be achieved in different ways. For example, the corresponding connecting means are first released, whereupon the entire fan attachment 1 is lifted off the housing 101. Outside, in particular above, the housing 101, the fan attachment 1 can then be turned before being placed back on the housing 101 and connected to it. Alternatively, a movable arrangement of the fan attachment 1 on the housing 101 (not shown in detail here) is also conceivable. For example, the fan attachment 1 can be pivotally connected to the housing 101, so that after at least one or more connecting means have been released, it can be rotated virtually freely around a structural axis of rotation without the fan attachment 1 having to be lifted off the housing 101.For this purpose, for example, two pivot bearings arranged centrally on one of two opposite longitudinal edges of the base 2 would be conceivable, forming a common axis of rotation around which the fan attachment 1 can then be rotated. Such a movable connection can of course also be designed to allow a combined rotational and translational movement of the fan attachment 1 relative to the housing 101, thereby resulting in a guided rotation of the fan attachment 1 on the housing 101.
