Definitions

• Ventilation device 1 Description:
• the invention relates to a ventilation device for a vehicle roof window, in particular for a sun roof that can be lifted and / or pushed, according to the preamble of claim 1.
• the vehicle roof is understood here to mean the entire body area of the vehicle provided with window areas and in particular the essentially horizontal roof area.
• a certain remedy can be provided in the case of such heating by a fan blower.
• these fan fans have the disadvantage of high power consumption, which places a heavy burden on the usual accumulator batteries serving as energy sources.
• ventilated roof hatches are provided on the roof level, which in their closed position allow permanent air exchange via concealed ventilation slots in the frame or in the hood-shaped cover.
• the DE-QS 30 03 224 proposes a motor-driven fan which is integrated in the open hood for the roof hatch in the area of the non-closable opening for permanent ventilation.
• a hood is usually of double-shell construction, ie it consists of a cover shell and a base shell, so that the heat-insulating effect of double-glazing is achieved.
• the object of the invention is to design a generic ventilation device in such a way that the ventilation effect is improved when the window is open, in particular simply glazed, in particular a liftable and / or sliding sunroof.
• Such a fastening strut can preferably be fixed on the frame of the vehicle roof window.
• "stationary” in the sense of the invention means that the fan is not moved when the translucent cover is opened and closed, that is, it always maintains its position in the window opening.
• a “fan” in the sense of the invention is at least the element that drives the ventilation flow, for example a fan-driven fan wheel that has blades.
• the fan motor itself can in principle be arranged at a separate location in the vehicle roof and, for example, drive the fan wheel by transmission, but the fan motor preferably drives the fan directly, that is to say without any transmission, and is driven with the Fan held together by the fastening strut in the desired position of the window opening.
• the invention inter alia, achieved the following advantages:
• the cover like any known window cover, can be pivoted and / or moved and / or removed in any manner without being hindered by the presence of the fan, which is particularly the case for lifting and / or sliding sunroofs because of the limited space Space is of particular importance;
• the support element in the form of at least one fastening strut, nozzle-like air passage openings between several fastening struts forming a structural unit promoting the desired air circulation - the formation of drafts is avoided because the entire window opening is available for air exchange; it is also possible for the fastening strut to have a lattice-like structure which can at most even fill the entire window opening;
• the fastening strut with the fan carried by it can be used as a complete unit in the window opening, in particular also releasably, so that it is suitable both for simple removal and for retrofitting and the usual window function, in particular with regard to light transmission, is so good as not affected.
• the energy source for the fan motor is at least one solar cell arranged on the vehicle body, preferably fixed on the at least one fastening strut, the desired ventilation effect is decidedly improved compared to known ventilation devices: in the case of strong sunlight, the forced ventilation is need for particularly large; In this situation, relatively more electrical energy is available for the fan motor than with a lower level of solar radiation, in which the need for forced ventilation is also lower.
• a solar-electrically driven fan wheel can rotate faster with relatively stronger solar light radiation and a correspondingly higher vehicle heating than with a lower solar light radiation and correspondingly lower vehicle heating.
• a further, very significant advantage of this solar-electrically operated ventilation device is the independence from any energy source of the vehicle, in particular the rechargeable battery, so that the ventilation device can work in continuous operation even when the accumulator battery, as with engine shutdown,
• the arrangement of the at least one solar cell on the at least one fastening strut, which also carries the fan, is particularly advantageous, since this arrangement facilitates installation, in particular when retrofitting, in the window opening and removal of the ventilation device No need - for example in the cold season - because neither wiring nor separate installation of the solar cells is required, but also a ventilation advantage because the at least one solar cell is located at the location where most of the sunlight-related heat energy is located he gets into the interior of the vehicle, namely on one that is directly irradiated by sunlight, in particular simply glazed, window surface.
• the "control behavior" of the ventilation device is improved on the one hand, because the fan motor receives the more energy the more directly the sun radiation affects the interior of the vehicle. On the other hand, this also creates a particularly favorable location for the solar cells, since they are protected from the weather and nevertheless have a good efficiency. It goes without saying that a generic ventilation device when using at least one solar cell arranged on the vehicle roof, in particular in the window opening of the ventilated window, also brings very great ventilation advantages if the support element for the fan on the translucent cover itself is fixed, such as in the roof hatch described above.
• all known solar cells can be used for the ventilation device according to the invention, it being possible to dispense with a more precise description of the solar cells because these are sufficiently known.
• Solar cells or solar cell arrangements which have a small thickness compared to the length and width of their light-sensitive surface have proven to be particularly advantageous; this can e.g. by assembling a large number of solar cells into a relatively thin plate.
• the light-sensitive surface of the at least one solar cell is preferably arranged parallel to the plane of the window opening in the region of the window opening itself.
• the ventilation flow can be concentrated as a result.
• the radiation shields partially obstructing the window opening also contribute to the fact that the air flow accelerated by the fan also reaches areas of the passenger compartment that are particularly remote from the window because it reduces the amount of circulating air in the area near the window.
• the arrangement of the fastening strut approximately in the middle of the window opening has proven to be particularly effective.
• a fastening strut is best suited, as is known from European patent application 85 104 805.
• the energy supply to the fan motor can also be switched on and off independently of the usual ventilation requirement, e.g. if the vehicle is not used for a long period of time or if the vehicle roof window remains airtight and has no forced ventilation slots.
• solar cells as an energy source, by optionally connecting the fan motor to the electrical system of the vehicle, if necessary, forced ventilation independent of the solar light radiation can be achieved.
• FIG. 1 shows a ventilation device in a view from outside the vehicle — view A according to FIG. 2;
• FIG. 3 shows the same ventilation device in the installed position in a liftable vehicle sun roof in an interior view - view B according to FIG. 2.
• a window opening (roof opening) with a sun roof 2 is provided, as shown in FIG. 3, which is supported at the opening edge of the roof opening by means of a frame 5 and has a translucent, disc-shaped cover 6 which can be raised at the rear.
• a support element 20 extends in the direction of travel, which is either formed in one piece with the frame 5, or can be inserted and fastened as a compact installation element between the front and rear frame strut 11, 10. This is preferably done by means of a releasable snap-in connection with the relevant frame struts.
• the support element 20 consists on the one hand of two fastening struts extending on both sides of the center line 9 laterally of an actuating device 26 for opening and closing the cover 6, which are designed as housing shells which are open at the top and which accommodate roller blinds 25 for pulling out laterally.
• the roll-up radiation protection screens 29 of the roller blind devices 25 have 13 eyelets 30 on their free longitudinal edge, by means of which the radiation protection sheets on the lateral ones Frame strut 16 or 17 of the frame 5 can be hung in hook-shaped fastening elements 28.
• the support element 20 Perpendicular to the fastening strut 24 of the support element 20 extend further fastening struts 22, which are arranged parallel to one another and leave slot-shaped ventilation openings 23 between them.
• a large-area recess 27 is provided between the fastening struts 24 on the one hand and the fastening struts 22 on the other hand, so that the cover 6 is unobstructed by the carrying element 20 can be opened and closed.
• the support element 20 thus has a lattice-like, flat structure which extends parallel to the window opening and within the window frame.
• the lid itself is an essentially planar translucent, generally slightly curved plate without any significant overhangs on the edge.
• the support element 20 carries a motor-driven fan, which consists of a fan wheel 4 having blades 3. This sits rotatably on the drive shaft 7 of an electrically driven, flat built fan motor 8, which is fastened in a trough 12 formed by the fastening struts 22. - * o -
• the carrying element 20 carries - likewise on its side facing the cover 6 - two planar solar cell arrangements 14, in each of which several, not individually shown, since known solar cells are combined to form a solar battery, the light-sensitive surfaces of which for the translucent cover (6 ) Clues.
• Current paths 18, 19 establish an electrically conductive connection to the fan motor 8.
• the ventilation device shown in FIGS. 1 and 2 represents a compact, self-sufficient, one-piece assembly that can be detachably inserted into the frame 5.
• the blades 3 of the fan wheel 4 can be translucent in order to prevent the passage of flickering light through the ventilation openings.
• the cover 6 has, due to a printing 6 'or the like known per se, a reduced light transmission, which is omitted in the area of the solar cell arrangements 14 in order to ensure the highest possible energy yield. With appropriate dimensioning of the more translucent cover surface, this does not impair the overall optical partial pressure of the cover, since the more translucent surface is located above the support element and the solar cell arrangement and is not recognizable from the passenger compartment.
• the fastening struts 24 can have a cover plate 25 on the window side. - "7 * ⁇
