    [0001] The invention relates to a cooling system of the passenger compartment of a motor vehicle. BACKGROUND OF THE INVENTION Air vehicle air cooling systems most often incorporate an air conditioner to ensure the thermal comfort of passengers positioned at the front and rear, by establishing in the passenger compartment a temperature below the external temperature. These systems ventilate cooled air mainly in front of the passenger compartment, so that they bring thermal comfort especially to the occupants located at the front of the vehicle. The seats at the back are less well ventilated, so they are also less refreshed. To improve the cooling of the seats at the rear, it is known, including FR2982533, nebulizing water in the ventilation ducts of the region located at the rear of the cabin. Concretely, the nebulized water microdroplets are diffused with the air flow intended for the ventilation and / or the ventilation of the places situated at the back, so that they evaporate causing a lowering of temperature of the fact latent heat of vaporization which is then absorbed.
    [0002] The condensed microdroplets that form at the inner walls of the aeration pipes are collected in a channel connected to the nebulizer to supply water, which allows to recycle condensed microdrops. OBJECT OF THE INVENTION The object of the invention is to reduce the amount of microdroplets that condense in such a system. SUMMARY OF THE INVENTION To this end, the subject of the invention is a ventilation and / or ventilation device intended to be mounted in a passenger compartment of a motor vehicle while being connected to a duct conveying a flow of air for the purpose of aeration and / or ventilation, to deliver this flow of air into the passenger compartment, this member comprising a grid intended to be traversed by the flow of air ventilation and / or ventilation, this gate being equipped with a nebulizer arranged to deliver microdroplets of nebulized liquid into the aeration and / or ventilation air flow downstream of the gate. According to an alternative embodiment of the invention, the ventilation and / or ventilation device according to the invention is disposed at the end portion of the duct conveying a flow of ventilation and / or ventilation air. . Preferably, the ventilation device and / or ventilation according to the invention is disposed at the portion of the conduit carrying a flow of ventilation and / or ventilation air opening into the passenger compartment. The ventilation and / or ventilation device according to the invention advantageously makes it possible to create a nebulization flow outside said duct, directly in the same direction as the aeration and / or ventilation air flow, which favors the evaporation of microdroplets from this nebulization flow and reduces or even eliminates the risk of condensation. The nebulization flow is thus directed to the body parts of the occupant of the vehicle regardless of its size and regardless of the size of the area to be treated. The sensation of freshness related to nebulization at the outlet of the aeration and / or ventilation device is located at the level of the nebulization flow. In addition, the microdroplets of nebulized liquid are generated directly in the passenger compartment, so that the risk of stagnation of liquid in the pipes is discarded. The invention also relates to a member as defined above, comprising a base in which the grid fits together while maintaining at least one degree of freedom with respect to this base so as to be orientable, so that the nebulizer s' orients with the grid when a user sets the orientation of that grid. The invention also relates to a member as defined above, wherein the gate and the base are connected to each other by a ball-type connection when the gate is fitted into the base. The invention also relates to an organ as defined above, in which the nebulizer is of piezoelectric type. The invention also relates to an organ as defined above, wherein the grid has a general shape of revolution and carries the nebulizer in its central region.
    [0003] The invention also relates to a member as defined above, wherein the gate carries a rotary closure flap located on the downstream face of this gate, being rotatable around the nebulizer between an open position to let the flow air flow and a closed position to close the passage of the air flow. BRIEF DESCRIPTION OF THE FIGURES FIG. 1 is a sectional side view of the ventilation and / or ventilation device according to the invention; Figure 2 is a perspective view of the ventilation and / or ventilation member according to the invention. DETAILED DESCRIPTION OF THE INVENTION The idea underlying the invention is to generate water microdroplets not in the ventilation or air conditioning system, but on the contrary downstream of each mouth where the air flow of ventilation is expelled. The microdrops are sprayed directly to the passenger compartment, in the ventilation airflow, so that the risk of water stagnation in the ducts is completely eliminated. As schematically illustrated in FIG. 1, the ventilation member according to the invention, marked by 1, comprises a base 2 which is secured to or integrated with an element 3 of the interior lining of the vehicle, such as the cladding element of FIG. the rear part of the center console of the vehicle. This base 2 which has a form of revolution has a central opening 4 forming a vent, and it is connected to a duct 6 for supplying fresh air which is itself connected to an air ventilation system of the vehicle.
    [0004] The inner surface of the central opening 4 has a generally cylindrical shape comprising substantially at mid-length a portion 7 having substantially the shape of a sphere ring, of larger diameter than the cylindrical portions 8 and 9 of this central opening 4 disposed on either side of the portion 7. This ventilation member 1 comprises a ventilation grille 11 whose outer periphery 12 also has an outer shape of a spherical crown complementary to the portion 7 of the base 2.
    [0005] As can be seen in FIG. 1, the outer periphery 12 of the grid 11 is fitted into the portion 7 having substantially the shape of a spherical crown of the internal opening 4 of the base 2, so that the grid 11 and this base 2 are connected to each other by a ball joint. A user can thus act on the grid 11 to position it so as to tilt it so as to orient the direction of ejection of the airflow by this ventilation member 1. This grid 11 which has a general shape of revolution, comprises radial arms 13, 14, 16, 17, which appear more clearly in Figure 2. Each arm has a general shape of a plane triangle and extends from the inner face of the periphery 12 to a central tubular portion 18 which extends along the axis of revolution of this grid 11, and in which is mounted a nebulizer 19. The four arms 13, 14, 16, 17 generally mask half of the surface of the opening 4, and this gate 11 still carries a shutter 21 which is rotatably mounted around the central tube 18. This rotary shutter 21 also comprises four triangular radial arms 22, 23, 24, 26 regularly distributed around the axis AX and each extending since its periphery to its central region ale. These arms 22, 23, 24, 26 also cover about half of the surface of the ventilation member 1. The flap 21 is thus rotatable about a quarter of a turn between a closed position in which it closes jointly. with the arms 13, 14, 16, 17 of the grid 11 the opening 4 completely, and an open position in which the arms 22, 23, 24, 26 of the flap 21 are above the arms 13, 14 , 16, 17 of the grid 11, to let the flow of ventilation air. The nebulizer 19 comprises a generally cylindrical body engaged and maintained in the tubular portion 18 of the grid 11, with a nebulizing head 27 which is flush with the side of the grid 11 which is downstream of the flow of ventilation air conveyed by the duct 6. This nebulizer 19 is supplied with liquid via a flexible pipe 28 located in the conduit 6, this liquid may be water, and it is also connected to electrical cables located in the conduit 6 and not represented.
    [0006] This nebulizer 19 is preferably piezoelectric type, but it can also be of any other type. When the ventilation is in operation, the microdroplets coming from the head 27 are thus generated outside the air supply duct 6, that is to say directly inside the passenger compartment of the vehicle, so that there is no risk of condensation of water in the ventilation ducts. Furthermore, thanks to the fact that it is directly carried by the grid 11, this nebulizer 19 is oriented with it when the user adjusts the inclination of the grid 11, for example to direct the air flow of ventilation to his face. It follows that the nebulizer 19 is always oriented according to the flow of ventilation air, so that the evaporation of microdroplets is continually promoted, which is further accentuated by the fact that the nebulizers 19 are generally very directional, that is to say that the microdrops are ejected parallel to the same direction.
    [0007] Overall, thanks to the mounting of the nebulizer 19 directly on the ventilation grid 11, the air flow and the flow of microdroplets are always oriented in the same direction, which greatly promotes the evaporation of these microdrops.
