    The invention relates to a fan unit for mobile use for ventilation of a field of application, in particular for the supply of fresh air contaminated with smoke or gases areas, as described in claim 1.
    DE 20 2011 052 116 U1 describes a fan unit for mobile use for fresh air supply to smoke contaminated areas. The fan unit comprises a base frame, a swing frame and an axial fan held on the swing frame. The base frame has a base frame zuwendbaren a footprint and a towering from the base frame rear frame part. The pivoting frame is pivotably mounted on the base frame about a first pivot axis of a first pivoting arrangement aligned in the horizontal direction. The axial fan has a drive unit, a fan wheel connected therewith in drive connection, and a fan housing accommodating the fan wheel.
    US 5,395,087 A describes a further fan unit for mobile use for generating an air flow emitted by this. The fan unit comprises a base frame and a swing frame mounted pivotally thereto. The axial fan is attached directly to the swing frame. The swing frame together with the axial fan can be pivoted in its relative position depending on the position of use and the associated air flow orientation about a arranged in the ground-level position on the base frame pivot assembly. By means of a latching device, the pivoting frame can be positioned in this adjusted position with respect to the base frame.
    A similarly designed fan unit describes the US 5,941,314 A. The fan unit comprises a base frame of a tubular frame. Side of the axial fan frame parts are provided, which are connected to each other at its rear side by means of a bow-shaped handle. On the two lateral frame parts of the axial fan is mounted in its position pivotally mounted in a bearing assembly with mutually spaced bearings. In this way, an inclination adjustment of the axial fan with respect to the base frame can also be performed around the bearing arrangement which is stationary with respect to the contact surface.
    The present invention has for its object to provide a fan unit, which has low transport dimensions and yet delivered in use or operation of the axial fan sufficient airflow and this is also pre-set in its flow direction in an angular range.
    This object of the invention is achieved in that the first pivoting arrangement for the lifting frame is arranged, on the one hand, in the region of the frame part projecting from the base frame and, on the other hand, in a first end section of the lifting frame facing the rear frame part, and the lifting frame from the rear frame part in the direction of a front side is formed protruding and a distance from the first end portion second end portion of the lifting frame in its vertical distance with respect to the base frame of the base frame closer rest position is in a raised position thereof adjustable, and that the lifting frame, a second pivot assembly is arranged with a second pivot axis which second pivot assembly is arranged distanced from the first pivot assembly, and that a support frame is pivotally mounted in its relative position relative to the base frame on the lifting frame about the second pivot axis of the second pivot assembly to thereby be able to perform a tilt adjustment of the air flow generated by the axial fan, and the axial fan is held with the interposition of the support frame on the lifting frame.
    The advantage achieved thereby is that such a compact base frame or a base frame can be created, which or which forms a stable, but portable recording for the axial fan. Since in the present embodiment, preferably, the base frame is formed continuously or trough-shaped, is provided by the pivotal movement of an end portion and the associated increase in the distance with respect to the base frame so better air flow on the bottom side in the axial fan between this and the base position provided by the lifting frame. By lifting for operation and the subsequent lowering for stowing a small size can thus be created for the arrival and removal, whereby for the operation and in the raised position of the lifting frame so mitanghoben the axial fan and so a more optimal air flow can be achieved , The additional provision of a separate support frame for the axial fan not only lifting and the associated further distancing the axial fan can be achieved from the bottom side arranged base frame, but also also a tilt adjustment of the axial fan are possible. Due to this additional tilt adjustment, the dispensing direction of the air flow generated by the axial fan to the respective operating conditions can also be carried out easily.
    Furthermore, it is advantageous if the lifting frame is formed by a bridge-like swivel arm. As a result of this bridge-like design of the swivel arm, it is possible for the latter to be mounted in a double-edged manner on the base frame, in particular on its rear frame part. The lifting frame projecting from the first pivoting arrangement forms a pivoting arm mounted on one side and can thus be adjusted with its end area remote therefrom from the rest position arranged at a smaller distance into the raised deployed position raised therefrom and at a greater distance from the base frame.
    Another embodiment is characterized in that the first pivot assembly is spaced from the base frame of the base frame in the vertical direction thereof. This can be a geometric mutually
    Order of the individual components of the swivel assembly and the associated lifting frame done so that a lower height is achieved for the arrival and removal than during ongoing operation.
    A further preferred embodiment is characterized in that the second pivot axis of the second pivot arrangement has a parallel alignment with respect to the first pivot axis. As a result, such a simple storage and tilt adjustment of the support frame held axial fan can be achieved.
    Another possible embodiment has the features that the base frame, in particular the rear frame part, for the adjustment of the lifting frame from its rest position to the raised position of use and vice versa a pivot drive is arranged. By providing a separate pivot drive so the operation can be substantially facilitated by the mutually engaged lever assemblies or joint arrangements. This makes it easier for not so strong people to be able to adjust the axial fan of the fan unit from the rest or transport position in the raised deployment position or operating position.
    A further embodiment provides that the pivot drive comprises at least one handle and at least one articulated lever, and the handle is pivotally mounted about a third pivot axis of a third pivot assembly arranged on the rear frame part, wherein the at least one articulated lever at its first end hinged to the at least one Handle and at its second end is pivotally connected to the lifting frame and the third pivot axis is aligned parallel to the first pivot axis. Thus, the raised use position or operating position of the axial fan can be achieved even at the first use by pivoting the handle and beyond also the movement of the entire fan unit from the transport to the place of use are made simpler.
    Another embodiment is characterized in that the third pivot arrangement is arranged in the vertical direction further apart from the base frame than the first pivot arrangement. As a result of this corresponding geometric arrangement of the individual swivel arrangements relative to one another, the entire overall height can thus be kept relatively low and nevertheless a simple adjusting movement for the lifting of the lifting frame for the operating person or the user is made possible.
    A further preferred embodiment is characterized in that a pivot bearing arranged at a distance from the third pivot axis is arranged on the at least one handle to form an actuating lever, to which pivot bearing the first end of the articulated lever is pivotally connected to the handle. As a result, it is possible to dispense with the provision of additional actuating levers, thus creating a simple compact unit. In addition, so by means of the handle not only a relief of the traversing movement of the fan assembly back to the place of use and be recovered from this, but also at the same time the lifting of the axial fan can be facilitated.
    Furthermore, it is advantageous if viewed in the direction of the second pivot axis distanced from each other, a hinge lever is provided, in each case the second ends of the hinge lever in alignment with respect to the second pivot axis are pivotally connected to the lifting frame. This can be done on the lifting frame a joint articulation of the hinge lever and storage of the support frame. In addition, however, as well as a both sides of the axial fan power transmission during the adjustment can be made motion and during operation. Thus, a stable and compact design can be provided.
    Another embodiment is characterized in that the handle is formed by a bow-shaped tubular frame and this is pivotable from an approximately oriented in the horizontal direction transport position in an approximately vertically upwardly projecting operating position. This can be done on both sides, simultaneous operation and adjustment of the associated with the handle hinge lever.
    Another possible embodiment has the features that the support frame is mounted with its first end portion on the second pivot assembly with the second pivot axis and protrudes with its second end portion in the direction of the rear frame part of the base frame. As a result, the size of the pivot drive and the components supporting the axial fan can be kept relatively low and still sufficient tilt adjustment of the support frame can be achieved together with the axial fan arranged thereon.
    A further embodiment provides that between the support frame and the lifting frame an adjusting device for the pivotal adjustment of the support frame is provided relative to the lifting frame. This makes it easier to set the relative position of the support frame with respect to the lifting frame and the associated inclination of the discharged air flow from the axial fan.
    Another embodiment is characterized in that the fan housing of the axial fan in a discharge region of the air flow from this a nozzle head with a central nozzle head axis in alignment with respect to a Lüfterradachse the fan wheel for adding water and optionally a foam mixture is arranged to the air flow and the nozzle head more Having distributed over the circumference arranged outlet openings. As a result, in addition to the improved air flow in this additional extinguishing agent or extinguishing medium can be added. As a result of the central arrangement, a directed admixture into the air flow can thus take place from the center of the axial fan.
    A further preferred embodiment is characterized in that the nozzle head is hat-shaped and is limited in the region of its outlet side by an end wall. As a result, an easily produced geometric shape of the nozzle head can be created, which can be easily connected to a corresponding counterpart in the region of the axial fan, in particular its fan housing.
    Furthermore, it is advantageous if the outlet openings are arranged in the end wall and each aligned in the direction of flow on the head of the nozzles kopfachse abge turned outward inclined outward. Due to the hat-shaped design with the provision of the end wall, a collecting space for the extinguishing agent to be distributed or admixed can thus be created within the nozzle head, whereby this can be added or admixed through the individual outlet openings through the air flow.
    Another embodiment is characterized in that a cross-sectional dimension of the individual outlet openings is designed to be decreasing in their throughflow direction. As a result, a better aligned, emitted from the nozzle head extinguishing agent jet can be created, which can be delivered in a more concentrated or bundled form.
    A further possible embodiment has the features that at least in each of the outlet openings in each case in the outlet region of the end wall a V-shaped groove recessed in each case with groove surfaces delimiting the groove is arranged in the end wall. As a result, an even better distribution of the extinguishing agent jet into the air flow can take place in addition to the directed exit jet.
    A further embodiment provides that in each case one of the groove surfaces of the groove formed cutting line is arranged to intersect with a longitudinal axis of the respective outlet opening. As a result, a symmetrical distribution of the emerging extinguishing agent jet can be achieved.
    Another embodiment is characterized in that the grooves are arranged in a star shape distributed over the circumference. As a result of this star-shaped arrangement of the individual grooves in their longitudinal extent, in each case from the center of the nozzle head or its nozzle head axis, a more uniform, better atomized addition of the additional extinguishing agent into the air flow can be achieved.
    A further preferred embodiment is characterized in that the end wall of the nozzle head is frusto-conical. As a result, the inclination of the individual outlet openings can be made simpler and more symmetrical with regard to their throughflow direction. In addition, however, a more symmetrical outlet of the additional extinguishing agent from the individual outlet openings can also be created in the region of the outside.
    Furthermore, it is advantageous if the end wall of the nozzle head has on the outside as well as in its center an aligned in the vertical direction with respect to the nozzle head axis Stirnendfläche. As a result, a defined completion of the nozzle head can be achieved. In addition, but also a better flow of the additional passage opening can be created in the center area.
    Another embodiment is characterized in that in the end wall of the nozzle head in its center region further at least one passage opening is arranged. Thus, an additional possibility can be created to add the extinguishing agent even better the air flow can.
    Another possible embodiment has the features that the at least one passage opening has a hollow-cylindrical flow cross-section. Thus, a uniform outflow of additional extinguishing agent from the nozzle head can also be achieved from its center.
    A further embodiment provides that the at least one passage opening parallel to the nozzle head is arranged extending axis. As a result, even in the center of the air flow, this can be mixed with an additional, predefined amount of extinguishing agent.
    Another embodiment is characterized in that the fan housing has in its exit region subsequent to the fan a circumferentially continuous, spirally arranged air guide. As a result, an air guide element in the outlet region of the fan housing can be created very easily, which can be produced in an endless manufacturing process, such as, for example, an extrusion process. As a result, additional mold costs can be saved, since otherwise a large number of different annularly designed air guide elements are to be formed. In addition, however, it is also very easy to take into account different size configurations of the fan housing. By arranged throughout the front or front side of the fan housing air guide so not only a correspondingly aligned air flow can be channeled to a sufficient extent, but also just a protective element can be created so as a Hineinlagen towards moving parts, such as the fan wheel, be prevented.
    Finally, it is aerodynamically advantageous if the air guide element in axial section with respect to a fan housing axis of the fan housing has an approximately streamlined air guide element cross-section.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    The term "in particular" is understood below to mean that it may be a more specific training or specification of an object or a method step, but not necessarily a mandatory, preferred embodiment thereof or a procedure must be.
    FIGS. 1 to 6 show a possible embodiment of a fan unit 1 for mobile use for ventilation, in particular for the supply of fresh air to areas contaminated with smoke and / or other gases, odors or the like and optionally for the additional supply of an extinguishing agent. The fan unit 1 is designed such that this can usually be spent by at least one person for the intended use of an emergency vehicle hän-ched to the site and there is used at least for the ventilation of the one or more applications. In this sense, the term "mobile" is understood. The fan unit 1 comprises a base frame 2, an axial fan 3, which is held on a preferably pivotally mounted to the base frame 2 lifting frame 4. The lifting frame 4 can also be referred to as a swing frame.
    The fan unit 1 can be parked or set up on a contact surface 5 indicated by a dash in FIG. 2. The base frame 2 may comprise a separate frame structure of several individual parts, wherein only one of the footprint 5 and thus base-side base frame 6 and at least one of the base frame 6 towering rear frame part 7 are described in more detail here.
    The lifting frame 4 may be mounted pivotably relative to the base frame 2 about a first pivot axis 9 defined by a first pivoting arrangement 8. In this case, the first pivot axis 9 is also horizontally aligned with the horizontal orientation of the footprint 5 and thus aligned parallel thereto. Furthermore, the first pivoting arrangement 8 may be arranged distanced from the base frame 6 of the base frame 2 in the vertical direction thereof. Instead of the pivoting movement about the first pivot axis 9, however, another form of movement of lifting the lifting frame 4, such as e.g. by a lever arrangement, a parallelogram lever arrangement or a link arrangement possible.
    The axial fan 3 may comprise at least one drive unit 10, a fan wheel in drive connection therewith and a fan housing 11 accommodating the fan wheel. The fan is rotatable about a Lüfterradachse 12 disposed within the fan housing 11, as is well known. The fan wheel axis 12 and a fan housing axis 3 defined by the fan housing 11 are preferably aligned with one another in a congruent or congruent manner.
    The first pivoting arrangement 8 for the lifting frame 4 is arranged in this embodiment shown here in the region of the uprising of the base frame 6 frame part 7 and in a first end portion 14 of the lifting frame 4.
    The first end portion 14 of the lifting frame 4 is facing the rear frame part 7 of the base frame 2. Furthermore, so that the lifting frame 4 protrudes from the rear frame part 7 in the direction of a front side of the fan unit Ivor. The lifting frame 4 can form a bridge-like swivel arm.
    By this forward projecting of the lifting frame 4 with its second end portion 15 from the first end portion 14, it is now possible that the second end portion 15 of the lifting frame 4 in its vertical distance with respect to the base frame 6 of one of the base frame 6 closer rest position raised in one of them Insert position with a greater distance is adjustable.
    On the base frame 2 can still be mounted a wheel 16, by means of which the base frame 2 is formed with all the attachments held on it manually movable. The wheelset 16 is preferably arranged in the rear part of the base frame 6 fixed thereto. The base frame 6 may be formed in the form of a kind of receiving tray, which can protrude from a bottom-side base laterally cheeks.
    At the rear side of the base frame 6 further protrudes in this embodiment, in each case in the corner areas, a post upwards, which together form the rear frame part 7. The uprights may be formed from one or more folded sheet metal parts, which are fixed to the base frame 6 and further in the transverse direction - ie in the direction of the first pivot axis 9 - are spaced from each other. The pivot axis 9 may be an imaginary or a physical, continuous axis, which forms the first pivot assembly 8 with corresponding associated bearing points.
    At the lifting frame 4, a second pivot assembly 17 is arranged or formed with a second pivot axis 18, wherein the second pivot assembly 17 is arranged at a distance from the first pivot assembly 8. The second pivot axis 18 in turn has a parallel orientation with respect to the first pivot axis 9.
    Furthermore, a separate support frame 19 is still provided, which is mounted in its relative position with respect to the base frame 6 pivotally mounted on lifting frame 4. For this purpose, a bearing assembly is provided between the support frame 19 and the lifting frame 4. As a result, a tilt adjustment of the air flow generated by the axial fan 3 can be performed. The axial fan 3 can thus be held on the lifting frame 4 with the interposition of the support frame 19. Preferably, this bearing assembly is arranged or aligned such that it is arranged in alignment with respect to the second pivot axis 18. The support frame is thus mounted pivotably about the second pivot axis 18 of the lifting frame 4. The second pivot axis 18 may be formed by an imaginary axis or else by a physical axis. For the implementation of the adjusting movement of the lifting frame 4 about the first pivot axis 9 and the associated lifting of its second end portion 15, a separate pivot drive 20 may be provided. With this pivot drive 20, both the lifting of the end portion 15 from its rest position to the insertion position and the back adjustment and the associated lowering can be performed back to the rest position. The second end region 15 of the lifting frame 4 with the second swiveling arrangement 17 arranged or formed there carries out a movement along a circular section about the first swiveling axis 9. The pivot drive 20 is arranged on the base frame 2, in particular the rear frame part 7.
    The pivot drive 20 comprises at least one handle 21, which is mounted in a third pivoting arrangement 22 about a third pivot axis 23 defined by this on the base frame 2, in particular the rear frame part 7, pivotally. The third pivot axis 23 is also aligned parallel with respect to the first pivot axis 9. Preferably, the third pivoting arrangement 22 is arranged further apart in the vertical direction from the base frame 6 than the first pivoting arrangement 8 and is therefore located above the first pivoting arrangement 8.
    Furthermore, the pivot drive 20 comprises at least one articulated lever 24, which has a first end 25 and a second end 26 spaced therefrom. The first end 25 of the articulated lever 24 is articulated to the handle 21 and the second end 26 is pivotally connected to the lifting frame 4.
    On the at least one handle 21, a pivot bearing 28 arranged at a distance from the third pivot axis 23 of the third pivot arrangement 22 is arranged or formed with the formation of an actuating lever 27. The actuating lever 27 is preferably an integral part of the handle 21 and this is formed by the handle 21 with. The first end 25 of the articulated lever 24 described above is articulated on the pivot bearing 28 and thus held tensile. Thus, the toggle lever 24 is connected on one side with the handle 21. At its second end 26 of the articulated lever 24 is pivotally connected to the lifting frame 4. Preferably, this connection is made in alignment with respect to the second pivot axis 18, about which also the support frame 19 is pivotally mounted.
    In order to be able to carry out a uniform adjusting movement of the lifting frame 4 together with the axial fan 3 held thereon with respect to the base frame 2, one of the hinge levers 24 is provided distanced from one another in the direction of the second pivot axis 18. Thus, the axial fan 3 can be accommodated in the space formed therebetween. The handle 21 may be formed by a bow-shaped or U-shaped tubular frame. The two legs of the tubular frame are mounted by means of their bearing arrangements about the third pivot axis 23 of the third pivot assembly 22 pivotally mounted on the rear frame part 7. In the rest position of the lifting frame 4, so the lowered position of the axial fan 3, the handle 21 or the tubular frame forming this has an approximately horizontal orientation, which can also be referred to as transport position for the arrival and removal. This position is shown in Fig. 2, wherein the handle 21 projects from the or from the rear frame parts 7 in the direction of the front side to the front. The swung-up or folded-up operating position of the handle 21, in particular of the tubular frame, is shown in FIG. In this case, the handle 21 or of these forming tubular frame extends vertically in approximately vertical direction. The swivel angle between the two previously described positions is approximately 90 °. However, it would also be possible to pivot the handle 21 or the tubular frame formed by it, from an orientation lying behind the rear frame parts 7, pointing in the direction of the footprint 5, into a rearwardly projecting operating position by approximately 90 °. In addition, it would also be possible to use this rearwardly projecting position for transport to the place of use - as an intermediate position - and only at the place of use to pivot the handle in a vertically upwardly projecting position. Thus, the lifting movement and thus also the adjustment could be increased.
    In FIGS. 3 to 6, different positions of the lifting frame 4 and of the supporting frame 19 mounted on the lifting frame 4 are shown in greatly simplified schematic form. The support frame 19 may preferably be mounted with its first end portion 29 on the second pivoting arrangement 17 with its second pivot axis 18 on the lifting frame 4. A second end portion 30 of the support frame 19 protrudes in this embodiment in the direction of the rear frame part 7 of the base frame 2. To adjust the relative position of the support frame 19 and the associated inclination of the Lüfterradachse 12 or the fan housing axis 13 with respect to the footprint 5 can not be closer shown and designated actuator serve. The actuator may e.g. be formed by an adjustable trained Bowden cable and / or Bowden cable optionally in cooperation with at least one gas spring. But it could also be an adjustable and adjustable gas spring or more of the same can be used. The actuator may e.g. be arranged between the support frame 19 and the lifting frame 4.
    Fig. 3 shows a simplified orientation and positions of the individual verschwbaren each other components, namely the lifting frame 4, the support frame 19, the handle 21 with the actuating lever 27 and the articulated lever 24 in its rest position and the transport position. The handle 21 or the pipe bracket forming this has an approximately horizontal or parallel alignment with respect to the contact surface 5. The lifting frame 4 is mounted on the first pivoting arrangement 8 on the rear frame part 7 and is in the lowered rest position or transport position. Here, the support frame 19 has an approximately horizontal orientation with respect to the footprint 5, whereby also held on the support frame 19 axial fan 3 and thus the Lüfterradachse 12 and the fan housing axis 13 also have an approximately horizontal orientation and thus parallel to the footprint 5 extend.
    The one or more articulated levers 24 each extend between the second end portion 15 of the lifting frame 4 and the pivot bearing 28 on the handle 21. Since on the handle 21 and at the same time between the third pivot assembly 22 and the pivot bearing 28 of the actuating lever 27 is formed by the Handle 21 during its adjustment movement from the transport position to the operating position by the associated Mitverschwenkung the operating lever 27 of the articulated lever 24 are moved and subsequently the second end portion 15 of the lifting frame 4 are raised.
    The raised position of the lifting frame 4 is shown in FIG. 4. As a result of this pivoting movement, in the present geometric arrangement of the individual components as well as bearing points, the support frame 19 is brought into a rearwardly inclined position, whereby the fan wheel axis 12 and the fan housing axis 13 are aligned upward in the upward direction. The air flow generated by the axial fan 3 is given up inclined. The included angle between the fan wheel axis 12 and the fan housing axis 13 and the footprint 5 may be e.g. 15 ° to 30 ° and also more. The angle may e.g. also be about 20 °.
    In Fig. 5 is basically the same position of the lifting frame 4 as shown in Fig. 3, but the support frame 19 and thus the axial fan 3 with the Lüfterradachse 12 and the fan housing axis 13 has been pivoted in an approximately horizontal orientation. The adjustment process can be performed with the previously described, but not shown and designated actuator.
    Finally, it is also shown in FIG. 6 that the support frame 19 and thus also the axial fan 3 with the fan wheel axis 12 or the fan housing axis 13 with its second end portion 30 has been pivoted further upwards about the second pivot axis 18 of the second pivot arrangement 17. Thus, the axial fan 3 with the Lüfterradachse 12 and the fan housing axis 13 is aligned sloping forward down. The falling angle may have the same amount or value as previously described for the upward angle. Thus, the air flow generated by the axial fan 3 can be pivoted in its direction with respect to the footprint 5 directed and adapted to the particular conditions of use.
    FIGS. 7 and 8 show a further embodiment of a component for the fan unit 1, in particular its axial fan 3, which is possibly independent of itself, wherein the same reference numerals or component designations are used again for the same parts as in the preceding FIGS. 1 to 6 , To avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 6 or reference.
    The air flow generated or discharged by the axial fan 3 can additionally be mixed with a preferred liquid additional medium, in particular an extinguishing agent and / or extinguishing medium. For this purpose, as can be seen from FIG. 2 in the center of the axial fan 3 in the area of the fan wheel axis 12 and the fan housing axis 13, a nozzle head 31 with a central nozzle head axis 32 is arranged in an exit area of the air flow from the fan housing 11. intended. The central nozzle head axis 32 is preferably arranged in alignment with respect to the fan wheel axis 12 of the fan wheel and / or the fan housing axis 13. The nozzle head 31 in this case has a plurality of preferably uniformly distributed over the circumference arranged outlet opening 33. The distributed over the circumference arranged outlet openings 33 serve to attach the nozzle head 31 via one or more feed lines not shown additional medium supplied to the circumferentially passing air flow or mix.
    The nozzle head 31 is preferably designed hat-shaped and is limited or closed in the region of its outlet side by an end wall 34. The end wall 34 of the nozzle head 31 may in turn be frusto-conical from the outer peripheral edge toward the center and thus towards the nozzle head axis 32. Furthermore, the end wall 34 on the outside as well as in its center may have a front face 35 oriented in a vertical direction with respect to the nozzle head axis 32.
    The plurality of distributed over the circumference arranged outlet openings 33 are arranged here directly in the end wall 34 and also formed there. In addition, the individual outlet openings 33 may each be in the flow direction on the kopkopfse 32 of the nozzle side facing away outwardly inclined aligned. This makes it possible to spend the additional medium passing through the outlet openings 33 into the air flow flowing circumferentially around the nozzle head 31. Furthermore, it can also be seen from FIG. 7 that a cross-sectional dimension of the individual outlet openings 33 in the direction of flow is formed decreasing from the inlet area to the outlet area. Thus, a certain nozzle effect and channeling of the extinguishing medium flow or extinguishing medium flow formed from the additional medium can be achieved.
    Furthermore, it is still possible that in at least some of the outlet openings 33 each in the outlet region of the end wall 34, a V-shaped groove 36 is recessed in the end wall 34 is arranged. The individual grooves 36 are each bounded by groove surfaces 37, which are aligned running towards each other and extending in the longitudinal direction parallel to each other. In that region in which the groove surfaces 37 intersect, they form a preferably straight line of cut 38 for each groove. Each of the individual grooves 36 is aligned in such a way that the section line 38 formed by its groove surfaces 37 is arranged to intersect with a longitudinal axis 39 of the respective outlet opening 33. Furthermore, it is advantageous if the grooves 36 are arranged in a star shape distributed over the circumference. Due to the additional arrangement of the grooves 36 in at least individual, but preferably in all of
    Outlet openings 33, a better distribution and additional fanning and atomization of emerging from the outlet openings 33 additional medium in the air flow into it can take place.
    In addition, it is still possible that in the end wall 34 of the nozzle head 31 in its center region - ie in the region of the nozzle head axis 32 - at least one additional passage opening 40 is arranged or formed. In contrast to the outlet openings 33 described above, the at least one passage opening 40 may have a hollow-cylindrical flow cross-section seen over its longitudinal extent. But it could also be a conically tapered design of the flow cross-section can be selected. Furthermore, in this embodiment, the at least one passage opening 40 parallel to the nozzle head 32 arranged extending in the end wall 34. In this way, an additional medium serving as an extinguishing agent or extinguishing medium can also be supplied to the center of the air flow which has merged after emerging from the fan housing 11.
    In the supplied through the nozzle head 31 additional medium may preferably be water. In addition, the water can also be mixed or added a foam-forming additive before passing through the nozzle head 31.
    The nozzle head 31 can represent alone in combination with the axial fan 3 independent training.
    FIGS. 9 and 10 show a further embodiment of a component for the fan unit 1, in particular its axial fan 3, which is possibly independent of itself, again using the same reference numerals or component designations as in the preceding FIGS. 1 to 8 for the same parts become. To avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 8 or reference.
    To simplify the construction of the outflow region from the fan housing 11, a spirally arranged, continuous air-guiding element 41 can be arranged or provided in the outlet region thereof adjacent to the fan wheel. In this case, not as conventionally used, a plurality of concentrically arranged air guide elements are provided, but it is starting from the outer edge region of the fan housing 11 toward the center of a continuous, arranged in a spiral air guide 41 used. This makes it possible, for example, to be able to form the air guiding element 41 in an endless strand with a corresponding profile geometry. After appropriate lengthening, the continuously formed air guiding element 41 is then fixed or held on holding arms, which are not described here in detail, while being arranged spirally in the region of the exit region at a preferably uniform distance from one another. Favorable flow conditions can be achieved if an air guide element cross section of the air guide element 41 in axial section with respect to the fan housing axis 13 thus in the flow direction - is formed approximately streamlined, as can be seen from Fig. 10. The exit-side end region of the air guiding element 41 can also be designed to be slightly flattened. Thus, flow losses can be reduced and also a better alignment and channeling of the discharged air flow can be achieved. The air guide 41 may also serve as a protective grid to prevent inadvertent Hineingreifen during operation towards the rotating fan.
    In principle, each of the swivel arrangements 8, 17, 22 described above can also have a plurality of bearing points arranged at a distance from each other, wherein the respective associated bearing points of each of the swivel arrangements 8, 17, 22 are arranged in alignment with one another. At several bearings per pivot assembly 8,17, 22, these are each arranged on the common pivot axis 9, 18, 23 or formed. This makes it possible to arrange the respective bearing points of the individual pivoting arrangements 8, 17, 22 laterally and thus distanced from one another in the transverse direction. The same applies to the arrangement and design of the pivot bearing 28th
    Between the fan and the outlet side arranged air guide 41 of the fan housing 11 may also be provided additional guide elements, which direct the flow of air generated by the fan in a predetermined or aligned flow direction or redirect. For this purpose, the individual guide elements, which are preferably arranged in a star-shaped manner distributed over the circumference, have a curved longitudinal course in the direction of flow. This longitudinal course can also have an approximately wing-like curvature. Furthermore, the individual guide elements can be designed to be insertable on both sides into correspondingly formed retaining recesses. Since in the region of the center and on the outside, the fan housing 11 has tubular housing parts formed, a two-sided mounting preferably also a replaceable mounting of the individual guide elements are provided on the housing parts.
    Furthermore, the fan housing 11 seen in the flow direction, may be formed divided. The coupling of the at least two fan housing parts may be effected at the mutually facing end sections, e.g. done by a locking device and / or a locking device. This could e.g. a bayonet lock or the like. An additional screw connection for secure mutual position fixation would also be possible.
    In addition, it would also be possible for the axial fan 3 to emit additional extinguishing agent in the form of an extinguishing foam in addition to the generated air flow or else through it. The addition in the air flow can be added by the nozzle head 31 described above. For this purpose, a so-called foam network in the outflow region of the axial fan, in particular following the air-guiding element 41, can additionally be arranged.
    As further known, the drive motor of the drive unit 10 can also drive its own generator. It may be formed by an internal combustion engine, the drive motor. Thus, one or more lighting means can be supplied with electrical energy directly in the area of the fan unit 1 by this power generator. Thus, even in the dark, an illumination of the working field around the fan unit 1 around at least during its operation. In addition, the arrangement of an energy storage in the form of a battery would also be possible.
    The embodiments show possible embodiments of the fan assembly 1, wherein it should be noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but rather various combinations of the individual embodiments are possible with each other and this variation possibility due to the teaching of technical action representational invention in the skill of those skilled in this technical field.
