- the reservoir comprises a water storage compartment and a nebulization compartment, the water storage compartment being provided with a filter of the purification device.
- the air quality system comprises a water softener.
- the water softener is arranged in a water passage channel between the storage compartment of water and nebulization compartment.
- the system an air inlet duct in the system provided with an air purification filter.
- the invention also relates to a ventilation device, heating and / or air conditioning for a motor vehicle, comprising a nebulization system as described above.
- FIG. 1 The figure illustrates a schematic view of a nebulizing system of a motor vehicle according to the present invention.
- the invention relates to a nebulization system of a motor vehicle, referenced 1 in the figure, also called nebulizer 1.
- the nebulizer 1 refreshes a flow of air F to the passenger compartment 2 of the motor vehicle, as it will be detailed.
- the nebulizer 1 comprises a water reservoir
- the reservoir 3 is advantageously composed of a water storage compartment 4, fluidly connected to another water compartment 5, called the nebulization compartment.
- the storage compartment 4 comprises an inlet 6 through which the nebulizer 1 is supplied with water.
- the inlet 6 has a flared shape from an external orifice 7 to an internal orifice 8 disposed in the storage compartment 4.
- the external orifice 7 has a diameter greater than a diameter of the internal orifice 8 so as to impart a funnel shape to the inlet 6 of the storage compartment 7.
- the funnel shape makes it easier to direct the water into the nebulizer 7.
- the nebulization compartment 5 is adapted to receive water from a nebulizing nozzle 9, as will be explained later.
- the nebulizer 1 also comprises the nebulizing nozzle 9 provided with a device for emitting sound waves, preferably ultrasound, referenced 10.
- the ultrasonic wave emitting device 10 comprises a piezoelectric element that vibrates when electrically powered.
- the piezoelectric element 10 is for example a quartz.
- the nebulizer 1 comprises a water transfer circuit 11 from the reservoir 3 to the nebulizing nozzle 9.
- the water transfer circuit 1 1 comprises a main circuit 12 between the tank 3 and the nozzle 4 and a drain circuit 1 3.
- the drain circuit 13 makes it possible to evacuate the water out of the nebulizer 1.
- the main circuit 12 and the drain circuit 13 are connected by a three-way valve 14.
- the main circuit 12 comprises a first branch 15 between the nebulizing compartment 8 and the three-way valve 14 and a second branch 16 between the three-way valve 14 and the nebulizing nozzle 9.
- the first branch 15 comprises a pump 17 for moving water.
- the nebulizing nozzle 9 comprises a water inlet orifice 18, connected to the second branch 16 of the main circuit 12.
- the nebulizing nozzle 9 also includes an internal water circulation channel, not shown.
- the water is subjected to the ultrasonic waves generated by the piezoelectric transmitter 10, which produces a mist of water droplets.
- the water droplets have a diameter depending on the vibration frequency of the piezoelectric emitter.
- the diameter of the droplets is less than 10 ⁇ .
- the nebulizing nozzle 10 also comprises an outlet orifice 19.
- the fog is directed towards the passenger compartment 2 of the motor vehicle, while a jet of water 20 coming from the internal circulation channel flows into the compartment 8.
- the nebulizer 1 comprises a fog outlet duct 21 connected to aerators 22.
- the fog circulates in the outlet duct 21 and then in the aerators 22, into the passenger compartment 2.
- the fog is mixed with an air flow F 'upstream of the aerators.
- the outlet duct 22 is advantageously provided with a flap 23 for controlling a fog flow.
- the nebulization compartment 5 comprises an inlet duct 24 of an air flow F in the nebulizer 1.
- the flow of air F helps to expel the fog in the duct 21.
- the nebulizer 1 comprises a water purification device 25.
- the water purification device 25 comprises at least one filter provided with a membrane provided with pores of less than 0.5 ⁇ m, and preferably less than 0.2 ⁇ m.
- Such a membrane makes it possible to eliminate most of the bacteria.
- the purification device 25 comprises two filters 26, 27.
- a first filter 26 is disposed in the internal orifice 8 of the inlet 6 of the storage compartment 4, which makes it possible to remove large diameter particles in the water, in particular when filling the reservoir.

- the filter 27 advantageously retains particles whose diameter is greater than 0.2 ⁇ .
- the purification device ensures that the water sprayed in the fog is healthy for the vehicle users.
- the purification at the inlet of the nebulizer and / or in the transfer circuit also makes it possible to supply the nebulizer not necessarily with drinking water but, on the contrary, to supply it with sources of mineralized and / or non-potable water, such as example condensates of a heating device, ventilation and / or air conditioning of the motor vehicle or by rainwater.
- the nebulizer also comprises a water softener 28.
- the water softener 28 allows in a known manner to reduce the hardness of water by reducing the amount of limestone, and thereby increases the life of the system.

- the nebulizer 1 also comprises an air filter 30 disposed in the air inlet duct 24.
- the purification of the air by the filter 30 allows an indirect purification of the water, since the air is in contact with the water in the tank and in the fog, and can contaminate these if it is not not purified.
- the air filter 30 is disposed downstream of a fan 31 disposed in the air inlet duct 24.
- the number of filters and / or the size of their filtering pores depends (ent) nebulizer, its dimensions and the dimensions of the vehicles.
- the sound wave emission device is not limited to a piezoelectric type nozzle but other wave transmitters are of course conceivable, depending on the desired amplitude and frequency.
