Definitions

  • the invention relates to a ventilation device according to the preamble of claim 1.
  • DE-A-2 942 482 describes a ventilation device with a housing, on the front of which a cover flap is pivotally arranged. This cover flap can be swung open if necessary to clear the flow path.
  • this known ventilation device has a wall in the interior of the housing which is screwed to a console of the fan housing by means of screws. The console mentioned is still connected to the housing by means of screws. It is therefore a not inconsiderable effort in the manufacture and assembly required to fix the fan housing and the wall mentioned in the interior of the ventilation device firmly and reliably. A not insignificant amount of time is required for the manufacture and assembly. Difficulties also arise if the interior of the ventilation device has to be made accessible for cleaning the interior or for maintenance purposes.
  • DE-U-7 801 023 describes a ventilation device which has a wall designed as an inspection flap, which is articulated on a front edge on the housing of the ventilation device. This inspection flap can also be locked on the housing by means of locking means.
  • Said wall contains a frame and a ventilation slide, each of which has slots and webs, which can be brought into the desired relative position to one another if required by moving the ventilation slide.
  • the structural design and mode of operation of a slide ventilation with frame and ventilation slide designed in this way is very different from a ventilation device of the type mentioned at the beginning.
  • the invention is therefore based on the object of developing the ventilation device of the type mentioned at the outset with little design effort such that simple manufacture and assembly and, moreover, also an easy cleaning possibility are provided, the actuation of the cover flap also allowing for a low design effort shall be.
  • the features specified in the characterizing part of claim 1 are proposed. Because of the wall, which is designed in a manner known per se as an inspection flap and is articulated on the front edge and can also be locked directly on the housing by means of locking means, the interior is easily accessible if required.
  • the opening provided in the inspection flap ensures simple and safe actuation of the cover flap by means of an actuator arranged in the interior via the actuating element. In this respect, no special effort is required during production.
  • the fan housing rests on the housing and also on the inspection flap via elastic support elements, as a result of which the fan housing can be easily locked and secured in the interior. During assembly, the fan housing is simply pushed into the interior until at least one support element bears against the inner wall of the housing opposite the inspection flap.
  • the inspection flap then only has to be closed and the locking means is used to lock it on the housing.
  • a separate fastening of the fan housing by means of screws or the like is not necessary.
  • tolerances that are too narrow do not have to be adhered to, since the elastic support elements compensate for this in a straightforward manner and also ensure that there is no play.
  • vibration damping is effected by means of the elastic support elements, so that vibrations from the fan and, in particular, from the fan motor are passed on to the housing in a correspondingly damped manner.
  • the embodiment according to claim 7 is characterized in that the cover flap and / or the inspection flap extend essentially over the entire height of the ventilation device. This enables a favorable integration of the ventilation device in a window frame or the like. If the ventilation device is further characterized according to claim 8, that the cover flap and / or the inspection flap extend substantially over the entire length of the ventilation device, the ventilation device overall has a largely closed surface on its front side. When integrated into a window frame or the like, no components that disturb the overall visual impression appear to the outside.
  • the embodiment according to claim 11 is characterized in that the fan housing has on its outer surface outwardly open longitudinal channels in which support elements are arranged.
  • the fan housing can thus be produced, in particular, by extrusion, the longitudinal channels mentioned also being produced at the same time; a special effort is practically not necessary.
  • the support elements which can be produced in a simple manner from endless profile material, are inserted into these longitudinal channels with little effort.
  • the fan housing has four longitudinal channels, which are each assigned in a corner of the interior of the housing.
  • the support elements arranged in the longitudinal channels thus engage in the corners of the housing of the ventilation device, whereby a rotation lock for the fan housing is achieved in a simple manner.
  • FIG. 1 shows a longitudinal section of a ventilation device with a U-shaped or box-shaped housing 2, the upper wall 4 and lower wall 6 of which can be seen.
  • the housing 2 is an extruded profile; its rear wall 28, which lies behind the plane of the drawing, connects the two walls 4 and 6 mentioned, an interior space 8 being formed.
  • In the interior 8 there are two fans 10, 12, which are designed as roller fans and are driven by a common electric motor 14.
  • a flow channel 16, 18 is provided symmetrically to the fans 10, 12 mentioned, through which the air drawn in by the fans 10, 12 can flow in the direction of the dash-dotted arrows 20, 22.
  • At the ends of the flow channels 16, 18 there are air passage openings 24, 26 which are arranged in the rear wall 28 lying behind the plane of the drawing.
  • FIG. 1 For purposes of this specification, the rear wall 28 is assigned to the outside, for example a window, while the inspection flap is assigned to the inside, that is to say the inside of the building.
  • the ventilation device shown thus serves to ventilate the room. If the ventilation device is to be used for ventilation, the ventilation through openings 24, 26 are to be provided accordingly in the inspection flap and the air through openings assigned to the fans 10, 12 are to be provided accordingly in the rear wall, the fans 10, 12 being rotated by 180 ° about the vertical axis 30 in that Housing 2 are used. No special effort is therefore required in order to be able to use the ventilation device either for ventilation or ventilation. In both cases, the direction of flow is predetermined by the arrows 20, 22, the flow within the outer housing essentially taking place in the direction of the longitudinal axis 32.
  • the upper and lower inner surfaces 34, 36 of the housing 2 are lined with insulating material 38, 40, which each have tooth-like webs 42, 44. As shown, these tooth-like webs 42, 44 protrude into one another at a distance, so that the flow channels 16, 18 formed in this way are approximately meandering.
  • the soundproofing effect can be influenced in the desired manner by suitable dimensioning of the tooth-like webs, their spacing and number. It is readily apparent that the flow paths can be increased by a corresponding extension of the overall length of the ventilation device, and thus the sound insulation can also be increased. On the other hand, the geometry of the flow paths can also influence the air throughput.
  • Suitable insulation material 46, 48 is also provided at the ends of the flow channels 16, 18; Corresponding insulation material is also on the rear wall and on the inspection flap:
  • FIG. 2 shows a perspective view of a ventilation device, the cover flap 54 of which is shown in the open position.
  • the inspection flap 56 can also be seen, which is also arranged on the front side 58.
  • the inspection flap has locking means 60 which can be actuated with a screwdriver or possibly with a coin in order to open the inspection flap 56.
  • the access panel 56 is provided with a single through opening Luf t 62 provided for the purpose by which the vent, for example a room, leaking air.
  • the ventilation device shown here has only a single fan.
  • the inspection flap 56 also contains an opening 64 for an actuating element 66, which is connected on the one hand to the above-mentioned actuator and on the other hand to the cover flap 54.
  • the cover flap can thus be opened or closed by means of the aforementioned actuator.
  • the cover flap and also the inspection flap each extend over the entire length of the ventilation device and equally at least approximately over the entire height of the ventilation device.
  • the box-shaped housing 2 can be seen with its upper wall 4, its lower wall 6 and the rear wall 28.
  • the housing 2 can be closed on the front side 58 by means of the inspection flap 56, the inspection flap 56 being shown here in the closed position.
  • the housing 2 has a longitudinal groove 72 in the region of its front edge 70, the front edge 70 having an at least partially cylindrical surface.
  • the inspection flap 56 engages with a lower, approximately arc-shaped extension 74 in the longitudinal groove 72 mentioned.
  • the inspection flap 56 is pivoted about the leading edge 70 on the housing 2.
  • the housing 2 also has an approximately L-shaped section 76 which on the one hand has the longitudinal groove 72 limited and on the other hand overlaps with its upper part 78 the arcuate extension 74.
  • a labyrinth seal is formed in order to prevent the penetration of outside air into the interior 8.
  • the upper stop of the inspection flap 56 on the upper wall 4 is also designed as a labyrinth seal, a tooth-like projection 80 protruding into a longitudinal groove 82 of the inspection flap 56 and angled webs 84 or mutually associated angled webs 84 or on both the upper wall 4 and the inspection flap 56. 86 are provided. This also forms a labyrinth seal, which ensures reliable sealing with little effort.
  • the arcuate extension 74 is designed or extends over such an angle that, after the inspection flap 56 has been pivoted in the direction of arrow 88 over a predetermined angular range of approximately 90 °, the inspection flap can be easily removed from the housing 2.
  • the cover flap 54 hinged to the inspection flap 56 can then also be removed at the same time.
  • the inspection flap 56 has a front longitudinal edge 90 to which the cover flap 54 is articulated.
  • the front longitudinal edge 90 also has an at least partially cylindrical surface and is gripped by a claw 92 of the cover flap.
  • the claw 92 is expediently designed such that the cover flap and inspection flap can only be detached from one another or connected to one another by relative movements in the direction of the longitudinal axis running perpendicular to the plane of the drawing. This reliably prevents accidental removal of the cover flap during operation or during cleaning or revision work.
  • the inspection flap 56 has a further longitudinal edge 94 at the top, which is designed in accordance with the longitudinal edge 90 already explained, so that the cover flap 54 can optionally be articulated on one of the two longitudinal edges 90 or 94.
  • cover flap and inspection flap thus includes a double joint in such a way that the cover flap 54 is articulated on the inspection flap 56, which in turn is articulated on the housing 2. Both flaps 54 and 56 extend essentially over the entire height, ie the distance between the upper wall 4 and the lower wall 6.
  • the cover flap 54 has a flat front surface 96.
  • dashed lines 98 the cover flap 54 can be easily adapted to the design of other components, such as e.g. a window frame or a door.
  • the cover flap 54 extends over the entire length, that is to say in the direction of the longitudinal axis running perpendicular to the plane of the drawing. It can be seen that the claw 92 forms a labyrinth seal together with the front longitudinal edge 90, the sealing effect being able to be improved by further webs or the like. Furthermore, a labyrinth seal is also provided on the upper stop between the cover flap 54 and the inspection flap 56, the cover flap 54 having a transverse web 100, the surface of which merges into an arcuate region of the cover flap 54.
  • the crosspiece 100 rests on the inspection flap 56 or on an associated crosspiece thereof. A simple labyrinth seal is created in order to reliably prevent air flow from or to the interior 8 when the cover flap 54 is closed.
  • the crosspiece 100 further increases the stability and rigidity of the cover flap 54. This ensures a tight seal.
  • the fan housing 68 has on its outer surface outwardly open longitudinal channels 102, in each of which there are support elements 104 made of resilient, elastic material.
  • the longitudinal channels 102 and also the support elements 104 extend over the entire length of the fan housing 68.
  • a total of four such longitudinal channels 102 are provided, which are arranged essentially in the region of the corners of the housing 2. It can be seen that a reliable locking or rotation lock of the fan housing is achieved in this way.
  • the support elements 104 namely engage in the corners or edges of the housing 2 in the manner shown and it can be seen that a reliable support is thus ensured.
  • the fan housing 68 When the inspection flap 56 is open, the fan housing 68 is simply pushed through the front opening between the two walls 4 and 6 of the housing 2 and is reliably stored in the housing 2 when the inspection flap is closed via the support elements 104.
  • the longitudinal channels 102 already mentioned above, which are provided on the front, are arranged on the two end regions 106, 108, which form the outflow channel of the fan housing 68.
  • FIG. 4 shows a section transverse to the longitudinal axis in the region of the flow channel, the cover flap 54 being shown in the open position.
  • the tooth-like web 44 takes up part of the height of the interior.
  • the rear wall 28 and the inspection flap 56 are also lined with insulating material 110, 112.
  • the locking means 60 can be seen, which have a rotatable pin 114 and a rotary lever 116 connected to this.
  • Rotary lift 116 is shown in FIG th position engages with the web 84 so that the inspection flap 56 is also held securely in the closed position. If the inspection flap 56 is to be opened, only the locking device 60 needs to be turned so far that the rotary lever 116 disengages from the web 84.
  • the web 84 is also part of the labyrinth seal explained above.
  • a weather protection profile 118 is also provided on the rear wall 28 in order to prevent the ingress of dirt, rain or other foreign bodies through the air passage openings present in the rear wall 28.
  • the connection between the weather protection strip 118 and the rear wall 28 or the outer housing 2 is made by means of connecting profiles 120 which engage in corresponding grooves or recesses in the weather protection strip 118 or the rear wall 28.
  • the open inspection flap is indicated by the dash-dotted lines 122 after pivoting over an angular range of a little over 90 °. It can be seen that the inspection flap 56 together with the covering flap 54 can now be removed from the outer housing 2, only the actuating element 66 still having to be detached from the covering flap 54.
  • the actuating element 66 is connected to the actuator mentioned above, passed through the opening 64 of the inspection flap 56 and articulated on the cover flap 54.
  • the housing 2 has longitudinal channels 124, into which fastening elements for the support wall 50 engage.
  • these fastening elements are designed as screws, the heads of which engage in longitudinal channels 124 and which are passed through corresponding bores in the supporting wall.
  • the support wall 50 has an approximately T-shaped projection 126 which engages in the longitudinal channel 124 present there.
  • This longitudinal channel 124 also serves to receive electrical lines to the fan motor or to the actuator.
  • the longitudinal channels 124 mentioned have undercut areas so that the fastening elements can also be reliably anchored.
  • the support wall 50 Perpendicular to the rear wall 28, the support wall 50 also has a bore 128 into which fasteners, in particular in the form of a screw, can be inserted. If necessary, a corresponding hole is made in the rear wall 28, so that the screw mentioned can also be passed through this hole in the rear wall. It is readily apparent that the ventilation device can thus be attached, for example, to an already existing ventilation grille, frame or the like.
  • the support wall 50 also has a connecting web 130 opposite the rear wall 28 with a recess 132 which has a larger diameter in comparison to the opposite bore 128. The aforementioned screw and a screwdriver or other tool for tightening the same can be passed through said recess 132.
  • the support wall 50 is not of solid construction, but has a number of cutouts 134, only the cutouts running in the direction of the longitudinal axis being visible here. With such cutouts, the greatest possible stability and strength of the support wall 50 are achieved with optimal use of material.
  • FIG. 6 An alternative embodiment is shown in FIG. 6, in which the longitudinal groove 72 is inclined by a small angle a with respect to the rear wall 28, that is to say in the illustrated installation position with respect to a vertical plane.
  • the projection 136 of the inspection flap 56 engaging in the longitudinal groove 72 is arranged in a corresponding manner inclined by a small angle or is designed accordingly so that it can engage in the longitudinal groove 72 in the manner shown.
  • only a slight swivel by the angle a is carried out, in order to subsequently remove the inspection flap 56 with the covering flap 54 in the direction of arrow 138 upward from the longitudinal groove 72 to be able to lift out.
  • the front area of the lower edge 140 carries out only a comparatively slight downward movement, so that practically no special free space is required there. Because of this design of the ventilation device, flush installation in window frames, walls and the like is made possible without any particular difficulties in the manufacture of the ventilation device.
  • FIG. 7 shows a section similar to that in FIG. 3, but here the cover flap 54 is pivoted about the front longitudinal edge 90 of the inspection flap 56.
  • the cover flap 54 was pivoted into the position shown by means of an actuating element 66, which is designed here as a spring.
  • the pivoted position of the inspection flap 56 is also indicated by the dash-dotted lines.
  • the inspection flap 56 can be released from the housing 2 by actuating the locking means in such a way that the inspection flap 56 and the cover flap 54 can be pivoted about the front edge 70 of the housing 2.
  • the fans 142 and also the other components of the ventilation device mentioned above are readily accessible. It is of crucial importance that when the inspection flap 56 is closed or when it is locked, the fan housing 68 is simultaneously locked in the housing 2. There are therefore no additional fastening means or the like provided for the fan housing 68, but the fan housing 68 is firmly and reliably locked in the housing 2 via the support elements 104.
