    [0001] The present invention relates to an air conditioning module of a passenger compartment of a motor vehicle.
    [0002] The invention applies in particular to air-conditioning modules for a motor vehicle, in particular comfort modules and to thermal conditioning installations for a motor vehicle, that is to say installations whose particular function is to heat, to cool, filter and / or dehumidify the air injected into the passenger compartment. There are known air conditioning modules intended to be arranged inside the passenger compartment of a motor vehicle. Such a module comprises a blower and is for example configured to be disposed under the seat of a front passenger and is connected with an inlet to a conditioned air flow line from the thermal conditioning installation arranged for example under the dashboard. The output of this module is connected to one or more air vents disposed for example at the location for the feet of the rear passengers. Such a module has for example the function of mitigating the pressure loss suffered by the flow of conditioned air in the circulation pipe. According to one development, the blower of such a module may be equipped with a multi-position control switch to allow the rear passengers to control the rear air flow independently regardless of the air flow set by front passengers.
    [0003] Also known modules installed in the ceiling of the passenger compartment of a vehicle, that is to say between the outer body and the roof of the vehicle.
    [0004] However, since the thickness between the body and the roof is quite small, it is most often simply air flow ducts whose outlet is connected to a vent and whose input is connected to a blower located for example at the rear of the vehicle.
    [0005] However, document US2014 / 0256244 discloses an air conditioning module equipped with a blower with radial blades. This known module is very bulky which comes in particular because the air is sucked along the axis of rotation of the blades and then returned in a radial direction. Thus, the suction and air discharge ducts are superimposed, then the thickness of the electric motor driving the blades is added thereto. US 6,286,328 discloses a thermal conditioning module comprising a roller blower. This module is hung from the ceiling and can not, because of its large size, be integrated into the structure between the bodywork and the roof sky. It is therefore noted that the air conditioning modules installed in the cabin are quite bulky so that a discrete integration while offering a large air flow is not possible.
    [0006] In addition, by being hooked to the roof structure of the passenger compartment, these air conditioning modules can impede the visibility of the rear passengers, which is undesirable and could even induce them to feel oppressive. In addition, wheeled blowers do not have optimum airflow efficiency. In fact, the aerodynamic efficiency of such impellers is only around 65% for the most efficient of them. Thus, if the efficiency of the blowers could be increased, it would be possible to significantly reduce the power consumption of the thermal conditioning installations, which is an important factor, especially for all-electric propulsion vehicles. Finally, the known blowers also generate noise which can hardly be further reduced and which is considered less and less acceptable to a user of the vehicle. The present invention aims at providing an optimized air conditioning module which notably makes it possible to be more discreetly integrated into a passenger compartment of a motor vehicle while having, as needed, a sufficient air flow, in particular for feed the areas at the rear of the passenger compartment. For this purpose, the subject of the invention is an air conditioning module for a passenger compartment of a motor vehicle, characterized in that it comprises an undulating diaphragm blower having an elongated air propulsion channel 15 of which air inlet shaft and air outlet shaft are aligned. Due to its small size and high efficiency, such a module can be easily integrated in various locations of a passenger compartment of a motor vehicle. The air conditioning module may furthermore comprise one or more of the following characteristics, taken alone or in combination: The blower comprises, for example, a blower box forming a propulsion channel and having a generally parallelepipedal and flat shape. In one aspect, the blower housing comprises two small sides parallel to each other and two long sides connecting the short and converging sides of the air inlet to the blower air outlet.
    [0007] 3032917 4 The blower housing has for example a thickness greater than 20mm and less than or equal to 60mm, especially less than or equal to 50mm and more particularly less than or equal to 40mm. In another aspect, the blower comprises at least one membrane mounted in the blower housing so as to be able to wave perpendicularly to the axis of the propulsion channel. Said at least one membrane may be mounted so as to be able to wave parallel to the long sides of the blower housing. In particular, the blower comprises at least one membrane waving actuator. In another aspect, the air conditioning module further comprises a functional air treatment unit disposed upstream or downstream of the blower. The functional unit comprises for example at least one of the 15 elements of the following group: a filter, an ionizer, a nebulizer, a heat exchanger, or a fragrance diffuser. The invention also relates to a thermal conditioning installation, comprising at least one heat exchanger, intended for example to be installed on a vehicle outside the passenger compartment, in particular in an engine compartment, characterized in that it is connected , in particular via an air circulation channel intended to open into the passenger compartment of the vehicle, to an air conditioning module as described above. The air conditioning module is for example intended to be installed in the passenger compartment of a vehicle, in particular under a seat, at the level of the central console between the front seats, at the level of the ceiling or at the level of the vehicle. rear range of rear seats. The invention also relates to a motor vehicle, characterized in that it comprises at least one air conditioning module 5 as described above and disposed in the passenger compartment of the vehicle. In particular, the air conditioning module can be installed under a seat, at the center console between the front seats, at the ceiling or at the back of the rear seats.
    [0008] Other advantages and features will become apparent upon reading the description of the invention, as well as the appended drawings in which: FIG. 1 is a simplified diagram of a vehicle equipped with a thermal conditioning installation comprising a module of 2 is a simplified perspective view of a blower used for an air conditioning module according to the present invention; FIG. 3 is a simplified schematic diagram of a side of an air conditioning module according to the present invention; FIG. 4A is a simplified schematic side diagram of a blower of FIG. 2 according to a second embodiment, FIG. 4B is a simplified schematic diagram of FIG. a blower of FIG. 2 according to a third embodiment, FIG. 5 is a simplified diagram of a vehicle equipped with an air conditioning module according to a second embodiment, FIG. Simplified diagram of a vehicle equipped with an air conditioning module according to a third embodiment, and Figure 7 is a simplified diagram of a vehicle equipped with a fourth mode air conditioning module. of realization.
    [0009] In the present description, the term "upstream" means that one element is placed before another relative to the direction of flow of the air flow. On the other hand, "downstream" is understood to mean that one element is placed after another relative to the direction of flow of the air flow. By upper, lower, upper and lower, reference is made to the arrangement of the elements in the figures, which generally corresponds to the arrangement of the elements when mounted in a motor vehicle. The following achievements are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference relates to the same embodiment, or that the features apply only to a single embodiment. Simple features of different embodiments may also be combined to provide other embodiments. Figure 1 shows a simplified diagram of a vehicle 1 equipped with a thermal conditioning installation 2 of a passenger compartment of a motor vehicle according to a first embodiment. The thermal conditioning installation 2 is installed outside the passenger compartment 3 of the vehicle 1, at the compartment 4 housing the engine, under the dashboard 5. Such a thermal conditioning installation 2 is also designated by HVAC. for "Heating, Ventilation and Air Conditioning" in English (heating, ventilation and air conditioning in French). This thermal conditioning installation 2 is formed for example by a main housing consisting of two plastic semi-shells, assembled to one another.
    [0010] This thermal conditioning installation 2 comprises, for example, at least one heat exchanger 6 such as an evaporator, but preferably at least two heat exchangers including an evaporator and a radiator, this to ensure, for example, heating, cooling and heating functions. air conditioning, demisting, dehumidification, etc.
    [0011] Although not shown in detail, the thermal conditioning installation 2 is connected to several air outlets, in particular vents at the windshield or at the middle console. The present thermal conditioning installation 20 furthermore comprises on the one hand an air circulation channel 7 intended to open into the passenger compartment 3 of the vehicle and, on the other hand, an air conditioning module 8 connected to the installation 2 via the air circulation channel 7. The air conditioning module 8 comprises a blower 13 to 25 undulating membrane. This module then acts as an amplifier or "booster" to increase the flow of air to the passengers at the rear of the passenger compartment 3.
    [0012] Due to its small size, the air conditioning module 8 can advantageously be installed under a seat 9 or at the center console between the front seats. Alternatively to better hide the module in view of the passengers at the rear of the passenger compartment 3, the air conditioning module 8 can be integrated into the seat structure so as to move with it forward and back when adjusting the seat position 9 by a user. In this case, the air flow line 7 comprises at its connection to the conditioning module 8 a flexible portion and / or bellows elongation. As can be seen in FIG. 2 showing the pulsator 13 with an undulating membrane in a schematic perspective view, the blower 13 comprises a blower box 21 of generally parallelepipedal and flat shape, and forming a channel 22 for propelling air.
    [0013] The blower housing 21 comprises two small sides 23A and 23B parallel to each other and two long sides 25A and 25B connecting the short sides 23A and 23B and converging from the air inlet 15 to the outlet of air 16 (see in particular Figure 3). By way of example, the blower housing 21 has a thickness E greater than 20 mm and less than or equal to 60 mm, in particular less than or equal to 50 mm and more particularly less than or equal to 40 mm, a length of between 150 mm and 250 mm, in particular equal to 200mm and a width LB between 120mm and 230mm, in particular equal to 180mm. Preferably, the length is greater than the width LB. The air propulsion channel 22 is elongated and straight (see FIG. 3). This is a straight channel. Indeed, the air inlet axis 27, that is to say an axis perpendicular to the cross section of the air inlet, and the air outlet axis 29 is that is, an axis perpendicular to the cross section of the air inlet, are aligned. FIGS. 3, 4A and 4B each show a simplified diagram of a pulsator 13 with an undulating membrane according to a first embodiment and a second embodiment, respectively. Figure 3 is a side cross-sectional view, i.e. looking towards the short side 23A which connects the long sides 25A and 25B. Figures 4A and 4B are cross-sectional views from above, i.e. looking towards the long side 25A which connects the short sides 23A and 23B. The blower 13 of Figure 3 comprises a single membrane 31 while the blower of Figures 4A and 4b comprises several membranes, in this case two pairs 31A and 31B.
    [0014] In both cases, the membrane or membranes 31, 31A, 31B are mounted in the blower housing 21 so as to be able to wave perpendicularly to the axis of the propulsion channel 22, this from the inlet 15 to the outlet 16 Pulser 13 as indicated by the arrows Fp in Figures 3 and 4A, 4B.
    [0015] More specifically, with respect to the embodiment of FIG. 3, the membrane 31 is sheet-shaped and is mounted so as to be able to wave parallel to the long sides 25A and 25B of the blower housing 21 as shown in the figure. For this purpose, the membrane 31 is held fixed or held with a means of elasticity adapted to its corrugation at its end 35 which is close to the air outlet 16 of the blower 13 and the blower comprises 3032917 10 for example at minus a diaphragm actuator 38 (not visible in the figures) which is fixed to the other end 37 of the diaphragm 31 near the air inlet 15 of the blower 13. The actuator 38 can for example comprise a rotary electric motor disposed outside the blower housing 21 and comprising an output cam to which is fixed a transverse rod fixed to the end 37 and performing a reciprocating movement in translation as indicated by the arrow Fm, perpendicular to the direction of propagation Fp. For this purpose, a light is for example made in one of the short sides 23A or 23B for the transverse rod. By undulating, the membrane 31 transports and propels into the recesses which propagate from the inlet 15 towards the outlet 16 according to the arrow Fp, a certain amount of air towards the outlet, this with on the one hand a ventilation efficiency approaching the 80% and secondly with a footprint 15 greatly reduced compared to rotary blowers of the state of the art for an equivalent flow. In addition, such a pulsator 13 undulating membrane is much more advantageous from a point of view of the aeroacoustic nuisance by reducing the effects of air shear than the blowers of the state of the art for an equivalent flow rate.
    [0016] The embodiment shown in FIG. 4A operates on the same principle as that of FIG. 3, but differs from it in that there are two pairs of parallel membranes 31A and 31B made in the form of bands oriented on the edge, that is to say that the strips are parallel to the short sides 23A and 23B of the blower housing 21.
    [0017] With regard to the rippling of the membranes 31A and 31B in the form of strips, four individual actuators, an actuator 38 for each membrane 31A and 31B can be provided so that the ripple power of each membrane can be individually controlled and adapted. Advantageously, it can be provided that the membranes of a pair of membranes 31A or 31B are waved in an antagonistic manner, which allows compensation of the vibratory effects. According to a more optimized development, a common actuator is provided for an adjacent pair of strips 31A or 31B, each actuator 38 being configured with a cam output (s) connected to the two adjacent strips 31A or 31B in order to put these in corrugation. Antagonist manner as shown in Figure 4A. It is thus possible to have a first air flow rate for a first pair of strips 31A and a second air flow rate for a second pair of strips 31B. According to a variant shown in FIG. 4B, the pairs of strips 31A and 31B are separated by a partition wall 36 parallel to the narrow sides 23A and 23B of the blower box 21. This variant also makes it possible to deliver airflows. left and right specific for the passengers at the rear of the passenger compartment 3. FIG. 5 shows another embodiment, which differs from that of FIG. 1 in that the air conditioning module 8 is installed at the ceiling 40 of the vehicle 1 and the module 8 is not connected to a thermal conditioning installation but directly draws air from the passenger compartment 3, for example above the front passengers to repress the air then at the level of the rear passengers. In addition, the air conditioning module 8 comprises a functional unit 42 for air treatment disposed downstream of the pulser 13 with an undulating membrane.
    [0018] Of course, an arrangement of the functional unit 42 upstream of the blower 13 is also conceivable. The functional unit 42 may comprise one or more of the following group of elements: a filter, an ionizer, a nebulizer, a heat exchanger, or a fragrance diffuser. Thus, the air conditioning module 8 can contribute independently of the thermal conditioning installation to the comfort of passengers in the passenger compartment. Figure 6 shows a variant of the air conditioning module 8 of Figure 5 which differs from it in that the module is installed at the rear shelf 50 of the rear seats. Figure 7 shows an embodiment similar to that of Figure 1 and is more specifically adapted to a public transport vehicle such as a bus.
    [0019] In this case, an air conditioning module 8 is installed at each passenger seat 9, each module 8 being connected to a thermal conditioning installation 2 disposed in the engine compartment. It will therefore be understood that, thanks to the small bulk of the undulating diaphragm blower 13, the air conditioning module 8 can easily fit into a passenger compartment. The use of these modules 8 with pulser 13 with an undulating membrane also makes it possible to reduce, for example, the power of the blower (s) 13 in the thermal conditioning installation 2.
    [0020] In addition, these modules 8 can be adjusted individually by the passengers so that it is even easier to create different areas at the vehicle level, the comfort of each zone being adaptable by the passenger who occupies in complete independence.
