    [0001] The present invention relates to a passenger ventilation system for a vehicle. Passenger ventilation system, passenger ventilation system or blower, in the automotive industry, the air distributors and air nozzles provided for all types of air ducts placed in or under the dashboard , in the air-conditioned roof top or for the hot or cold air blower behind and / or under the front seats of a vehicle interior. Document DE 100 03 798 84 describes a device for ventilating a vehicle cabin with two air outlets in which the displacement of the meeting points of the two air jets generates diffuse flow ratios as well as jets of air. The air is large and allows adjustment in any flow direction. Adjustment of the flow direction can be achieved by means of adjustable air guide blades placed in the air outlets. DE 102 35 526 A1 also describes the reciprocal influence of two air jets after their entry into the passenger compartment of the vehicle. The presence of movable air guide slats makes it possible to adjust the direction of the air flows. The reciprocal closing and opening of the air channels by means of additional shutters also makes it possible to produce a fan effect. The present invention provides a passenger ventilation system for a vehicle, characterized by the following features: - the passenger ventilation system comprises a plurality of airflow channels with a common air outlet area for evacuating a vehicle. mass flow of total air desired; each air flow channel is connected to the air outlet zone such that the air outlet zone is supplied with a mass flow rate of air through the air flow channel ; - The mass flow rates of air can be controlled relative to each other so that they are superimposed in a mass flow of total air. Said system is further characterized by one or more of the following features: at least one airflow channel among the airflow channels comprises a regulating valve, in particular a valve, permitting reducing the cross-sectional area of the airflow channel, and - the mass flow rate of air through the airflow channel with the control valve can be controlled through the control valve; 10 - the passenger ventilation system can be connected to an air conditioner of the vehicle, and - at least one airflow channel among the airflow channels is configured such that the mass flow rate of air through the airflow channel can be regulated by the air conditioner; By local separation of the air flow channels from each other; at least one airflow channel among the airflow channels comprises an angular control for varying an angle of the airflow channel, and the mass flow rate of air through the airflow channel having the angular control can be controlled; the angular control comprises rigid air guide elements making it possible to direct the mass flow rates of air; the angular control does not include air guiding elements for directing the mass flow rates of air; the air flow channels comprise a main flow channel and a secondary flow channel; the passenger ventilation system comprises, upstream of the main flow channel, means for producing an air flow duct; pressure difference between the main flow channel and the secondary flow channel, and - the mass flow rate of air through the secondary flow channel can be controlled by these means; the air flow channels comprise two upper airflow channels and two lower airflow channels; The upper airflow channels are oriented with respect to the lower airflow channels at a variable angle; each airflow channel has fixed air guide elements; in the air outlet zone, and the air guiding elements are oriented such that the mass airflows of the upper airflow channels and the lower airflow channels cross ; the air outlet zone is configured or constructed so that the mass airflows interact within the passenger ventilation system; the air outlet zone is configured or constructed so that the mass flow rates of air interact outside the passenger ventilation system. The arrangement according to the invention has the advantage that no adjustable lamella needs to be provided, the orientation of fixed lamellae or even only housing walls sufficient to influence the flow of air. The pulses of the different air flows are designed here so that the direction of the resulting air flows can be changed. The parameters of these pulses are the direction, the flow rate and the air mass. The additional parameters that can influence this principle are the arrangement of the air channels having a reciprocal influence as well as the position of the flux interaction point. Other advantageous configurations of the present invention are given below. It suffices in principle to vary one of the six mentioned parameters - cross section, flow rate, air mass, direction, arrangement of the air channels having a reciprocal influence as well as position of the flux interaction point. However, it is also possible to compromise between these parameters or to bring several in interaction or all. Here, for example, we think of an identical cross-section with a different mass flow rate, at an identical mass flow rate with different cross sections, at a mass flow rate specific to each channel or at a single mass flow rate distributed between the channels, at a variation of mass flow through an air conditioner, shutter flaps or by varying the cross section - respectively continuously or in stages - at a change of direction using air guiding elements, a change of direction by variation of the position of the channel, a change of direction by connecting or disconnecting an evacuation or suction bypass at a fixed predefined direction by a flow channel; an arrangement of the channels, for example in the form of a triangle, a star or a straight line, with a different shape of the channels - for example round or rectangular - with the same or different numbers of c anal, at the position of the interaction point of the streams - for example by separation in space or by meeting the individual air flows in a channel - or at an output adjustable between a concentrated or diffuse output. An exemplary embodiment of the present invention is shown in the drawing and will be described in more detail later.

    [0003] Figures 1 to 4 illustrate the basic structure of a passenger ventilation system 10 for a vehicle according to a first, second, third and fourth embodiment. In these embodiments, the passenger ventilation system 10 comprises, respectively, two air flow channels 11, 12 and an air outlet zone 20 common to the two airflow channels 11, 12 for evacuate a desired mass flow of total air. Each of the two air flow channels 11, 12 is here connected to the air outlet zone so that the air outlet zone is fed with a mass flow rate of air rhi, rh2 through the air outlet zone. air flow channel 11, 12 respectively. In the first embodiment of FIG. 1, a mass flow rh is divided for this purpose while in the second embodiment of FIG. 2, two air flow channels 11 and 12 are completely separated. one of the other. The air mass rates rh1, rh2 may be controlled relative to one another such that they overlap to form a mass flow rate of total air whose direction may be controlled according to the embodiments discussed by changing the cross section A1, A2 and / or the flow rate rhi, rh2 of at least one of the two air flow channels 11, 12. The direction of the total air mass flow can be adjusted by causing a change in the pulses of the individual air mass rates rhi, rh2 interacting. The air flow channels 11, 12 according to the first and second embodiments have for this purpose a valve 15 to reduce its respective cross section A1, A2 while the air mass flow rates rhi. , rh2 illustrated in Figures 3 and 4 can be regulated through an air conditioner connected to the passenger ventilation system 10 of the respective vehicle. The third embodiment of Figure 3 in this case shows a local separation 16 of the two air flow channels 11, 12 relative to each other. The fifth embodiment of FIG. 5 explains the possible change of direction by modifying the angles a 1, a 2 of two interacting air mass flow rates. In this case, a resulting total mass air flow appears as a function of the angle α 1, a 2 of the two air flow channels 11, 12 which influence each other. In the case of FIG. 5, at least the angle α1 of the upper channel 11 can be modified for this purpose by bringing it into the end position 17. The angle of the resulting mass air flow is then oriented from the horizontal according to Fig. 15 to the upper edge of Fig. 5. A further example of angular control is shown in Fig. 6 using a sixth embodiment. The air guide members preferably rigidly placed in the flow here direct the two mass airflows rhi, rh2 in the desired direction. A comparable effect can also be achieved without the use of air guiding elements. In the seventh embodiment of FIG. 7, a mass flow rh is subdivided for this purpose while in the eighth embodiment of FIG. 8 two air flow channels 11, 12 are completely separated. one of the other. In the ninth embodiment of Figure 9, the change of direction is effected by overpressure or underpressure exerted at the outlet of flow. If necessary, the underpressure is used to draw air at the outlet of the flow.
    [0004] This makes it possible to deviate according to the illustration the constant main flow rhi downwards. Alternatively, a dynamic pressure or overpressure is produced. This can be used if necessary to blow air at the outlet. This allows, according to the illustration, to deflect the horizontal main flow rh, upwards. The tenth embodiment of Fig. 10 also utilizes this principle of action, with a slightly different geometric shape. An eleventh embodiment is shown in FIG. 11. In this exemplary embodiment, the passenger ventilation system 10 comprises two lower airflow channels 11, 12 and two flow channels. The upper air 13, 14 is oriented at a fixed angle α relative to the lower airflow channels 13, 14. The four blowing points all further have fixed lamellae, so that the mass flow rates of air intersect. A mass flow rate of total air defined as a function of the mass flow rate of air having the greatest impulse is obtained. In the calculation example of FIG. 12, all airflow channels 11, 12, 13, 14 provide the same pulse. The resulting flow of air is thus oriented, starting from the surface of the drawing, towards the observer. As is evident from the exemplary embodiments of FIGS. 13 to 18 with the aid of a twelfth, thirteenth, fourteenth, fifteenth, fifteenth and sixteenth embodiments, the air flow channels 11, 12, 13, 14 may vary in their shape and number as well as in their angles and their arrangement with respect to each other and their size. The shape of the air outlet zone is particularly important in this case. The area in which the interacting air mass flow rates occur can be in the channel as well as outside the channel or even vary from one to the other. Of course, the invention is not limited to the embodiments described and shown in the accompanying drawings. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of the invention.
