This system, described in EP2018189 A1, comprises an air freshener solution for sliding on a vehicle air blower, comprising a plurality of fragrance carriers and a circular air rectifier, comprising circumferentially openings for directing the flow of air through the carrier spaces. By rotating the opening over the space with the fragrance carrier, the flowing air is aromatized and the aromatized air is led out of the space of the perfumery unit to the surroundings. However, this system no longer directs the aromatized air and it leaves the space of the perfumery unit directly and does not allow the air to go outside the compartments and thus not be aromatized.

In the current state of the art, a device is known which rotatably directs the inlet and outlet multi-way valves by means of which it directs the air through the chambers in which the odor is located. This system is described in document JP2019043206 A, it contains a solution of a perfumery unit with multi-way valves for the selection of fragrances for perfuming air. It discloses the location of the perfumery unit in the vehicle's air conditioning system, several separate fragrances and the technical equivalent of including air supply and exhaust tubes. However, the system does not allow the holder to exchange fragrances and air flow through the perfume unit without passing through the fragrance compartments.

In the prior art, a device with different fragrances stored in a cartridge and with rotating disks is known, each of the disks comprising an opening for the passage of air, so that one of the fragrances can be selected for perfuming by rotating the disks to the same extent. This system, described in EP3265332 A1, comprises a perfumery unit solution comprising a circular carrier with segments comprising different fragrances, the air stream for perfuming being discs with an opening at the bottom and from the top of the carrier. The system does not allow the holder to remove fragrances and air flow through the perfumery unit without passing through the fragrance compartments.

The essence of the invention

The aroma device for perfuming the interior of the vehicle comprises the main body, with a supply pipe connected to the inlet opening, a discharge pipe connected to the outlet opening, said at least two chambers for accommodating fragrances and a connecting space consisting between the supply body and the discharge pipe. in that both the supply and discharge pipes are rotatably mounted, connected to the drive and each of the pipes is provided with at least two openings in the chamber and at least one opening in the connecting space, these openings being azimuthally offset relative to each of the pipes.

There is therefore the possibility of scenting and not flavoring the space of the vehicle, as well as the possibility of regulating the intensity of the odor by switching the air flow path.

The openings in the tubes are thus positioned in such a way that they allow the selection of one or more of the fragrances.

In a preferred embodiment, the inlet and outlet pipes are provided with three openings in the chamber, so it is possible to use three fragrances with different fragrances.

It is advantageous if the supply pipe drive is designed as the first servomotor connected to the control unit and the discharge pipe drive is designed as the second servomotor connected to the control unit. The independent control thus allows any rotation of the tubes relative to each other and thus a combination of several air paths at once, either for a combination of fragrances or a combination of fragrances with the passage of air through the connecting space for smoother regulation of odor intensity.

In another preferred embodiment, the supply and discharge pipe drive is realized as a servomotor connected to the control unit, and further mechanically connected via a transmission to the supply and discharge pipe for their simultaneous rotation. If a gear is thus arranged between the pipes for handling both pipes at the same time, this easily ensures synchronization and also savings by using a single servomotor.

Preferably, a front cover provided with brackets for attaching at least two fragrances is detachably attached to the main body. The front cover can therefore be removed for convenient exchange of fragrances.

The main body is preferably placed in one or more covers of the device for the best possible air sealing.

The control unit is preferably connected to the vehicle infotainment with a user interface.

The inlet and outlet pipes preferably have three openings in the connecting space at their beginning and end.

Exemplary embodiments of the invention

An exemplary embodiment of the invention is a perfuming unit for perfuming the interior of a vehicle, for example in an air conditioning system or an independent perfumery system.

The perfumery unit for perfuming the car interior according to Fig. 1 comprises a main body 5, two symmetrical covers of the device 2a, 2b, a front cover 3, which serves as a carrier for the user-selected fragrances Ja, 1b, Je. Fragrances J_a. 1b, It is made as scented polymers in the shape of a rectangle. The cover 3 is provided with holders for accommodating three fragrant bodies 1a, 1b, 1c, as can be seen in Fig. 2. The cover 3 is attached by means of two clips 4a, 4b, which slide into the groove on the main body by inserting body 5 together with the cover 3.

According to Figs. 3 and 4, there are two rotating tubes inside the main body 5 of the device, a supply tube 6a and a discharge tube 6b. The perfuming unit also comprises an inlet opening 10 designed in this exemplary embodiment as an inlet tube for the supply of air and an outlet opening 11 designed as an outlet tube for the removal of perfumed air or air which has not been perfumed. In this exemplary embodiment, a drive servomotor 8 with a gear 9a, 9b, which is designed as several gears and shafts, serves to ensure the movement of the rotating tubes. When the servomotor 8 is rotated, the supply pipe 6a and the discharge pipe 6b then rotate against each other so that it is always possible to set the position for selecting any of the fragrances or for selecting the passage of air through the connecting space without perfume. Alternatively, however, the supply pipe 6a and the discharge pipe 6b can each be connected to a different drive, for example a servomotor 8, which can each be controlled separately by a control unit 7. Correct positioning of the rotary tubes (6a, 6b) and timing is ensured by the control unit 7.

In Fig. 5 and Fig. 6, the supply pipe 6a and the discharge pipe 6b are identical and have along their length openings 101, 102, 103, 201, 202, 203 placed in the chambers in such a way that they can be rotated towards the fragrance chambers 12. body 1 or one or more openings 101, 102, 103, 201, 202, 203 oriented into the chambers. Furthermore, the supply pipe 6a and the discharge pipe 6b each comprise at the beginning and end three openings 104, 105, 204, 205 in the connecting space which, when rotated relative to each other on the supply pipe 6a and the discharge pipe 6b, direct air flow out of the fragrance chambers 12. The rotation of the supply and discharge pipes 6a, 6b takes place simultaneously, so by turning one of the openings into the supply pipe chamber 6a towards the chamber 12, the opening into the discharge pipe chamber 6b also rotates. Simultaneous mutual movement of the supply and discharge pipes 6a, 6b provides one transmission 9a connected to the servomotor 8, which transmits the torque in the same way to the supply and discharge pipes 6a, 6b. Thus, the synchronized rotation system ensures a through open position only through a certain chamber 12, or a free flow without odors through the openings 104, 105, 204, 205 into the connecting space located at the beginning and end of the rotating tubes 6a, 6b. wherein the position of the fragrances 1 remains the same. The intensity of the odor is controlled by alternating the flow of air through the separate chambers 12 through the fragrance bodies 1 and the flow outside the chambers, i.e. through the openings 104, 105, 204, 205 into the connecting space at the beginning and end of the rotating tubes 6a, 6b. The time intervals are controlled by the control unit 7.

The flavoring device can be placed either by integration into the air conditioning system or as an additional perfumery system, independent of the air conditioning system. In the exemplary circuit of FIG. 7, the air is taken from the central air conditioning HVAC and is driven by the central air conditioning fan 18 by means of a supply hose to the flavoring device, where it is enriched with odor. Subsequently, the perfumed air is bifurcated and blown into the air distribution part of the side blowers 17. The perfuming unit is controlled by the vehicle infotainment 13.

In another exemplary embodiment according to FIG. 8, air is sucked in by an additional fan 14 from around the center console and forced through the flavoring device into the outlet slot 16 at the rear of the armrest at the rear blower 15. The perfuming unit is also controlled by vehicle infotainment 13.
