Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air outflow surface divided into an upper outflow area and a lower outflow area, which are arranged in parallel and spaced apart from each other uniformly over the upper outflow area. A first thin plate set consisting of a plurality of fixed thin plates,
A second lamella set consisting of a plurality of oscillating lamellas, spaced parallel to each other and uniformly distributed over the lower outflow region and arranged to oscillate about its longitudinal axis, and all oscillates The present invention relates to an air guide nozzle for defrosting a side glass of a vehicle and for ventilating an interior chamber, which has an adjusting element for adjusting a swing angle of a thin plate to be freely selected.

[0002]

2. Description of the Related Art In the case of a known air guide nozzle of this type (see German Patent DE 18 12 283),
The outflow areas of the air outflow surface are separated from each other by a through separating wall and connected to the respective air guiding system via separate connecting short pipes, the upper outflow area of which is located in the warm air system,
The lower outflow area is located in the fresh air system. The fixing lamella in the upper outflow region extends vertically and is adjusted towards the side window. In the lower outflow region, the vertically oriented oscillating lamella is held in the frame in such a way that it can oscillate about its longitudinal axis. The frame itself is supported in the nozzle frame by a swing shaft extending at right angles to the swing thin plate. In the case of this air guide nozzle, the outflow direction of the fresh air flow used to ventilate the internal chamber is well controlled in all directions by the rocking of the rocking frame on the one hand and the rocking of the rocking lamina on the other hand, In that case, the defrosting of the side glass is maintained by the flow of warm air regardless of the ventilation adjustment of the internal chamber. However, this air guiding nozzle has the disadvantage that the ventilation of the inner chamber and the intended blowing of air to the inner chamber area and the passengers' bodies there are carried out only with fresh air, not with temperature-controlled warm air, This often results in unpleasant ventilation.

A similarly known air guide nozzle for ventilating the interior of motor vehicles (German Patent 37198).
No. 35C2), the splitting of the air outflow surface into separate outflow areas is abandoned and the entire nozzle is supplied with only one temperature-adjustable airflow. 2 continuous in the flow direction
Each of the two planes is provided with a lamina set of mutually parallel oscillating lamellas which can be oscillated together about parallel oscillating axes, and the oscillating lamellas of these two lamina sets extend transversely to each other. There is. Adjustment of the oscillating lamellas in both lamella sets is done by a single slider. The slider can therefore be moved in two directions parallel and perpendicular to the plane of the lamella. When using this so-called dulled nozzle for ventilating the side glass and for defrosting, it is very difficult to adjust the lamellas quickly and accurately. Furthermore, it is not possible to direct the warm air flow to the desired interior area and to the passengers' bodies located there for the defrost time.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to direct an air guide nozzle of the type mentioned at the outset to the side glass when the defrosting of the side glass is such that the air stream is positioned quickly and correctly. Auxiliary passenger-directed partial air flow is also assisted, while on the other hand, in the absence of defrost demand, the nozzle's total air outflow cross section is involved in the ventilation of the interior chamber and is inexpensive to manufacture. It is to improve so that it can be done.

[0005]

According to the invention, the object is to provide an air guide nozzle of the type mentioned at the outset in which the fixed and oscillating lamellas extend parallel to the dividing line of the outflow region and are in a common plane. A plurality of other oscillating lamellas, which are located inside and parallel to this, are distributed evenly over the upper and lower outflow regions in parallel with one another and have their longitudinal axes centered. At least one other adjusting element (adjusting slider, cross slider) is arranged pivotably in the center, these oscillating lamellas extending at right angles to the fixed and oscillating lamellas of the first and second lamella sets. This is achieved by being able to adjust its swing position by.

When the air guiding nozzle according to the invention is installed in the front panel of the interior compartment of the motor vehicle, which also houses the instrument panel, according to the rules, the so-called mirror triangular plate of the side window and the air supply passage for guiding the conditioned air. Near the connection, the air flow coming out of the upper outflow region flushes the side glass as well as the interior chamber region at the height of the steering wheel, due to the fixed lamellas present there, in front of or behind the fixed lamella in the direction of air flow. Then, by means of another oscillating lamella, which is arranged so as to intersect with this, all or part of it is diverted to the side window or the interior chamber area. Independently of this, other airflows are selectively and additionally directed to the side glass through the rocker lamella set which is arranged across it via the lower outflow area or the area ventilation of the interior chamber.

There are third and fourth lamella sets 29, 30 consisting of moving lamellas 31. The oscillating lamellas 31 extend at right angles to the oscillating lamellas 27 of the second lamella set 26 and the fixed lamellas 25 of the first lamella set 24, respectively. The oscillating thin plates 31 of the fourth thin plate set 30 are arranged so as to be uniformly distributed in parallel with each other over the lower outflow region 232 at intervals.
Are arranged over the upper outflow region 231 in parallel with each other and at even intervals. The web 22 is followed by a web wall 32 towards the connecting stub 213. The web wall 32 penetrates the plane of the swing thin plate 31. The swing shafts 33 arranged at the centers of both ends of the swing thin plate 31 are held on the one hand by the web wall 32 and, on the other hand, by corresponding recesses on the opposite side faces of the box frame 211.

A common adjusting element in the form of an adjusting slider 34 is provided for rocking the rocking lamina 27 of the second lamina set 26 and the rocking lamina 31 of the third lamina set 29. The adjustment slider 34 is a thin plate set 24,
It is formed so as to be movable in two perpendicular directions parallel to the planes of 26, 29 and 30 (see FIG. 1). In that case, the adjusting slider 34 is connected on the one hand to the oscillating lamella 27 of the second lamella set 26 and on the other hand to the oscillating lamella 31 of the third lamella set 29 as follows. That is, the horizontal movement of the adjustment slider 34 parallel to the web 22, that is, horizontal, causes the swing thin plate 31 of the third thin plate set 29 to swing about the swing axis by the same swing angle. The swinging thin plates 27 of the second thin plate set 26 are connected so as to be rotated by the same swinging angle by the vertical vertical movement of the adjusting slider 34 at right angles thereto. In this case, the adjusting slider 34 acts on at least one of the oscillating lamellas 31 to 27 and the other oscillating lamellas 31 to 27 are mechanically connected thereto. To actuate the oscillating lamellas 31 in the fourth lamella set 30, a cross slider 35 is provided which is movable parallel or horizontal to the web 22. This cross slider 35 is connected to at least one of the oscillating lamellas 31 in the upper fourth lamella set 30, while on the other hand this oscillating lamella 31 is mechanically attached to the remaining oscillating lamellas 31 of the fourth lamella set 30. Is bound to. Cross slider 35
The desired swing adjustment of the swing thin plate 31 in the fourth thin plate set 30 is performed by the movement in one direction or the other direction. The oscillating lamellas 31 in the fourth lamella set 30 are particularly dimensioned such that the movement of the cross slider 35 to the end positions on both sides causes the oscillating lamellas 31 to overlap at their edges, thereby closing the entire upper outflow region 231. It is arranged.

The air blocking flapper 36 is rotated at the free end of the box frame 211 via an operating wheel (not shown) whose operating circumferential surface projects. As a result, the air cutoff flapper 36 increases or decreases the cross-sectional area of air flow in the connecting short pipe 213. The amount of air flowing out from the air guide nozzle 20 can be adjusted by the air cutoff flapper 36.

On the other hand, in the air guide nozzle 20 shown in the longitudinal sectional view in FIG. 4, the rocking thin plates, here designated by 31 ', are integrally discharged as the third thin plate set 29'. It has been modified to extend as an integral part over both outflow areas 231, 232 of the surface 23. Therefore, since the swing thin plate 31 'is held on both side surfaces of the box frame 211 by the swing shaft 33' arranged near the rear edge thereof, the web wall 32 is omitted. Further, since the through swing thin plate 31 'is moved via the adjusting slider 34, the cross slider 35 shown in FIG. 3 is also omitted.
