Fragrance delivery system
A fragrance dispensing system for an aircraft that includes a fuselage defining a cabin interior and an environmental control system (ECS). The ECS includes a source of air that moves air between the source of air and the cabin interior along an airflow path, a mixer unit in airflow communication with the source of air and positioned downstream from the source of air in the airflow path, at least a first air duct positioned in the airflow path between the mixer unit and the cabin interior, and a fragrance dispensing unit positioned between the air source and the cabin interior along the airflow path. The fragrance dispensing unit is configured to dispense at least a first fragrance into the airflow path.
1. An aircraft comprising:
a fuselage defining a cabin interior, and
an environmental control system that includes
a source of air, wherein air flows between the source of air and the cabin interior along an airflow path,
a mixer unit in airflow communication with the source of air and positioned downstream from the source of air in the airflow path,
at least a first air duct positioned in the airflow path between the mixer unit and the cabin interior, and
a first fragrance dispensing unit positioned between the air source and the cabin interior along the airflow path, wherein the first fragrance dispensing unit is configured to dispense at least a first fragrance into the airflow path.
2. The aircraft of claim 1 wherein the first fragrance dispensing unit includes a scent assembly that contains a first fragrance oil that comprises the first fragrance.
3. The aircraft of claim 2 wherein the first fragrance dispensing unit is configured to selectively dispense at least first and second fragrances into the airflow path.
4. The aircraft of claim 1 wherein the first fragrance dispensing unit is configured to dispense the first fragrance into the mixer unit.
5. The aircraft of claim 1 wherein the first fragrance dispensing unit includes a first fragrance cartridge therein that includes a scent assembly with the first fragrance therein, wherein the first fragrance cartridge includes a cover that is movable between a closed position and an open position, wherein the first fragrance is dispensed when the cover is in the open position.
6. The aircraft of claim 5 wherein the first fragrance dispensing unit includes a second fragrance cartridge therein that includes a scent assembly with a second fragrance therein, wherein the second fragrance cartridge includes a cover that is movable between a closed position and an open position, wherein the second fragrance is dispensed when the cover is in the open position.
7. The aircraft of claim 5 wherein the fragrance dispensing unit includes a first fragrance module that includes a rotatable portion that is in engagement with the first cartridge, and wherein rotational movement of the rotatable portion moves the cover of the first cartridge between the open and closed positions along a linear path.
8. The aircraft of claim 1 wherein the first fragrance dispensing unit is configured to selectively dispense at least first and second fragrances into the first duct, and wherein a second fragrance dispensing unit is configured to selectively dispense at least first and second fragrances into a second duct.
9. The aircraft of claim 8 wherein the first fragrance dispensing unit includes a first fragrance cartridge therein that includes a scent assembly with the first fragrance therein, wherein the first fragrance cartridge includes a cover that is movable between a closed position and an open position, wherein the first fragrance is dispensed when the cover is in the open position, wherein the first fragrance dispensing unit includes a second fragrance cartridge therein that includes a scent assembly with the second fragrance therein, wherein the second fragrance cartridge includes a cover that is movable between a closed position and an open position, wherein the second fragrance is dispensed when the cover is in the open position.
10. The aircraft of claim 1 wherein the fragrance dispensing unit is in electrical communication with an electrical control unit, wherein the first fragrance dispensing unit is configured to selectively dispense the first fragrance based on instructions from the electrical control unit.
11. The aircraft of claim 10 wherein the electrical control unit includes a human machine interface, and wherein the instructions can be provided via human input.
12. An aircraft comprising:
a fuselage defining a cabin interior that includes at least a first zone, and
a fragrance delivery system disposed in the cabin interior, wherein the fragrance delivery system includes
a first fragrance dispensing unit positioned in the first zone, wherein the first fragrance dispensing unit includes a first fragrance cartridge that includes a first scent and a second fragrance cartridge that includes a second scent,
a first electronic control unit positioned in the first zone and in communication with the first fragrance dispensing unit,
a second fragrance dispensing unit positioned in the first zone, wherein the second fragrance dispensing unit is in communication with the first electrical control unit, and
a human machine interface in communication with the first electronic control unit,
wherein the first fragrance dispensing unit is configured to selectively dispense either the first fragrance or the second fragrance.
13. The aircraft of claim 12 wherein the first fragrance dispensing unit includes a first fragrance cartridge therein, wherein the first fragrance cartridge includes a first near field communication portion that includes information related to the first fragrance cartridge, wherein the first near field communication portion is in communication with a receiver in the first fragrance dispensing unit, and wherein the information related to the first fragrance cartridge is communicated to the human machine interface.
