Description

AIRCRAFT SANITIZATION SYSTEM

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Application No. 63/055,146, filed July 22, 2020, the entirety of which is incorporated herein by reference.

FIELD OF THE INVENTION

[0002] The present invention relates generally to an aircraft sanitization system, and more particularly to an aircraft sanitization system that includes a portable trolley for cleaning portions of the aircraft.

BACKGROUND OF THE INVENTION

[0003] Commercial airline operations are being disrupted by the COVID 19 crisis. Airline passenger trips have reduced significantly causing a financial crisis in the industry.

Airlines are interested in developing and deploying technology, products, and solutions that will clean, sanitize, disinfect, or even sterilize the A/C interior before, during, or after flight. Some solutions include wiping surfaces with cleaning liquids, replacing the materials used in high-touch areas with materials that have anti-microbial properties, adding films to high touch surfaces with anti-microbial properties or using UCV lights as pathogen killing devices. In addition, airlines are interested in measuring airplane crew, ground staff, and passenger body temperatures. They use this temperature reading as an indication of a virus infection in the person tested.

[0004] Although many concepts are being developed and proposed to airline operators that kill pathogens, such as the COVID 19 corona virus, there is still a need to ensure these technologies, products, or solutions also meet the industry needs of efficiency and safety at the same time. Moreover, commercial products are being adapted for use on the aircraft, but these products may not meet the industry requirements to allow them to fly or to be certified as Airborne Equipment.

[0005] Companies design, manufacture, certify and sell galleys or galley monuments (the food preparation, cooking and disposal area), galley equipment or inserts (the products that go in the galley) and catering food carts (the trolleys that bring the food into the aircraft, and are used to remove waste and trash from the aircraft or perform other functions). For example, see U.S. Patent Publication No. 2021/0039789 and U.S. Patent No. 10,406,253, the entireties of which are incorporated by reference herein. Galley equipment or inserts include ovens, trash compactors, coffee makers, beverage chillers, air chillers, beverage trolleys and the like.

[0006] There are cleaning units that contain UV lights meant for sanitizing aircraft cabin surfaces. However, these cleaning units are larger than catering trolleys and are not certified for flight. These cleaning units must be brought on-board the aircraft while the aircraft is grounded and used when no passengers are on the aircraft.

SUMMARY OF THE PREFERRED EMBODIMENTS

[0007] Aircraft flying in commercial service have to be fuel efficient and safe to fly. The airframe manufacturers, their suppliers and the Government regulators, such as the Federal Aviation Administration (FAA) in the United States and the European Union Aviation Safety Agency (EASA) have developed procedures, regulations, processes and certification requirements to ensure products that are introduced into the aircraft are safe, are low or sufficient weight, low or sufficient power, and compact in volume. Herein the FAA will be used as the exemplary governmental regulatory agency or administration. The FAA has certification requirements that must be met in order for a galley monument, for example, to be installed in an aircraft. [0008] Many galley inserts require electrical power, have human to machine interfaces (such as LCD touch screens), are designed to use available space in an efficient manner, are designed to be placed (inserted) into the galley, and are certified to meet all FAA and industry requirements.

[0009] The galley monuments that contain these equipment or inserts are strong enough to contain the galley equipment during expected turbulence, abnormal aircraft maneuvers, and during crash landings. These galleys also are designed to provide the needed power to this equipment, to manage the power used by the equipment, and are designed in a practical, ergonomic way, to allow the crew to use the equipment in a safe efficient way.

[0010] During galley design and certification the airline customer or airframe OEM will specify which type of trolley or galley equipment is needed for that specific aircraft configuration. The galley then will be unique and optimized for weight and power for that specific configuration. The galley monument and/or other monument also includes a plurality of insert spaces or docking stations that have a size or volume. In a preferred embodiment, the size (e.g., envelope) stays the same so that the new/sanitization insert fits into the space of the old insert.

[0011] Trash compactors may be considered a galley insert. A specific trash compactor produced by the applicant, Safran Cabin is discussed herein. This galley insert trash compactor has unique design requirements and challenges. For instance, the trash compactor is installed under the counter or work deck (e.g., in the place of a catering trolley), whereas, other galley inserts using electrical power (such as ovens) are installed above the counter. This galley insert trash compactor when installed in the galley is heavier than other inserts (having an empty weight of 80 Kg typical versus 20 Kg typical), and it is designed to hold a significant amount of trash (up to an additional 30 Kgs of weight). This product also uses a large amount of aircraft power, up to 2 Kwatts. A variant of this product has the ability to be removed from the galley during flight, to move up and down the aisle, allowing the flight attendant to add waste to the internal trash receptacle. This product generally takes the form of a trolley.

[0012] The Safran Cabin trash compactors are installed in aircraft. The galleys installed in these aircraft are designed and certified to contain the weight of these compactors and to provide the needed power for theses compactors. These trash compactors have been produced and are in service for approximately the last 20 years. There are a significant amount of aircraft (typically wide-body aircraft like B777, B787, A340, A350 or A380) that have galley monuments installed that have insert spaces or docking stations that have been certified for this trash compactor. In a preferred embodiment of the present invention, this trash compactor is replaced with a sanitization insert.

[0013] In a preferred embodiment, a galley cleaning station is created within the galley. Galley inserts and/or trolleys are replaced with cleaning products or sanitization inserts. These inventive inserts are designed to have a mass equal to or less than the galley insert or trolley replaced (e.g., trash compactor, as discussed above). In a preferred embodiment, the inventive inserts are designed to use equal or less power than the galley insert replaced (e.g., trash compactor, as discussed above). In a preferred embodiment, the inventive inserts have or fill approximately the same volume and physical interface as the replaced galley insert or trolley. Where electrical power is used, the EMC signatures of the inventive products meet industry requirements, and have similar electrical loads as the replaced galley insert.

[0014] One such inventive cleaning insert is made to be moveable within the aircraft and may replace the trash compactor on the aircraft, uses similar or less power than the replaced trash compactor, and has an installed weight less than or equal to the max weight of the replaced trash compactor. This inventive cleaning trolley can be installed in the galley. In an exemplary embodiment, the galley envisioned to be used for the installation (typically on wide-body aircraft like B777, B787, A340, A350, or A380) is already designed, certified and qualified to receive the replaced trash compactor. It will be appreciated by those of ordinary skill in the art that by designing the inventive cleaning trolley to fit within the trash compactor design envelope, certification and airline acceptance will be achieved without the need for recertification. In addition there is a ready installed fleet of aircraft with provisioned galleys flying. For airlines, the recertification process with the FAA can be expensive, cumbersome and will require aircraft to be grounded or for the monuments to be removed in order for the aircraft to continue to fly. Therefore, it is advantageous for new monument inserts to be below the power and weight requirements of the previous or replaced insert so that the monument does not have to be recertified.

[0015] When the cleaning trolley is located in the galley (the home galley, or docking station) it may be connected to aircraft power. In a preferred embodiment, the trolley includes a battery, a battery management system, and UV light control device (e.g., a controller) inside the cleaning trolley. The cleaning trolley can then be operated without being directly connected to the galley. In another preferred embodiment, the trolley includes a tethered power supply that is attached to the galley or another component that includes a power source. In this embodiment, the cleaning trolley includes a power cord preferably retained inside the trolley. In this embodiment, as the cleaning trolley moves down the aisles the aircraft provides the needed power. [0016] In another embodiment, only the detachable light source is included or used. The detachable light source preferably includes a battery, battery management system, and light control device or system. The battery can be charged when the trolley is positioned in the home galley docking station. The operator can then selectively clean surfaces during the flight (typically high touch areas like lavatory doors).

[0017] The cleaning trolley may include a Bluetooth receiver and/or transponder or other wireless communication capability. The galley, which the cleaning trolley is installed in, may also include a Bluetooth receiver and/or transponder. Other galleys on the aircraft, and other cabin equipment on the aircraft (such as seats, or passenger service units) may also include Bluetooth receivers and/or transponders. Using Bluetooth mesh networks physical tracking algorithms, either the galley (docking station) or the cleaning trolley will establish the location of the cleaning trolley within the cabin. A controller can either provide information to the operator on which surfaces to clean, via, for example, a human-machine interface (HMI) on the cleaning trolley, or which position to place the trolley to achieve optimum cleaning, or the device itself, or the home galley docking station can control the location of the trolley. In an embodiment, to enable movement of the cleaning trolley includes motors and a drive mechanism to propel the trolley up and down the aisle (or someone can manually push the cart up and down the aisle). UV light requires a certain amount of time to kill bacteria and virus. By using a controller and a mesh network tracking system, the controller can use algorithms to ensure the trolley has been to the correct locations, and has been at the needed locations for the minimum required time duration. This cleaning assurance can be made by instructing the operator where to go, for how long, or the device itself can determine where to go and for how long. This location tracking and assurance function may also be deployed for the removable light source or removable (or non-removable) misting dispenser (e.g., when to dispense the sanitizing and/or scent mist and/or for how long) or any other embodiment described herein as well. [0018] In an embodiment where only the detachable cleaning devices, such as the UV wand or the misting delivery system are utilized or installed in an aircraft, a smaller docking station can be installed into the galley monument or other monument. It will be appreciated that galleys are designed to provide power to inserts that are smaller than trash compactors. These inserts, such as coffee makers, are installed above the work deck in the galley, still require power, and have a mass up to 20 Kgs (with respect to certification). The inventive docking station can take the place of these inserts or can be fitted or positioned directly in to the galley structure. Standard docking stations can be placed in multiple galleys in the aircraft. For example, the aircraft may include multiple detachable cleaning devices.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] The following description and drawings are illustrative and are not to be construed as limiting. Numerous specific details are described to provide a thorough understanding of the disclosure. However, in certain instances, well-known or conventional details are not described in order to avoid obscuring the description. References to one or an embodiment in the present disclosure can be, but not necessarily are references to the same embodiment; and, such references mean at least one of the embodiments. If a component is not shown in a drawing then this provides support for a negative limitation in the claims stating that that component is "not" present. However, the above statement is not limiting and in another embodiment, the missing component can be included in a claimed embodiment.

[0026] Reference in this specification to "one embodiment," "an embodiment," "a preferred embodiment" or any other phrase mentioning the word "embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the-disclosure and also means that any particular feature, structure, or characteristic described in connection with one embodiment can be included in any embodiment or can be omitted or excluded from any embodiment. Furthermore, any particular feature, structure, or characteristic described herein may be optional.

[0027] Referring now to the drawings, which are for purposes of illustrating the present invention and not for purposes of limiting the same, FIGS. 1-4 show a sanitization system 10 that is configured to be installed in an aircraft 100 that includes a fuselage 102 that defines a cabin interior 104. In a preferred embodiment, the sanitization system 10 includes a monument 12 having a plurality of walls 14 that define a plurality of docking stations 16. In an exemplary embodiment, the monument 12 is a galley monument. However, it will be appreciated that the monument can be any type of monument typically found an aircraft, such as a lavatory monument, storage monument, etc. [0028] In a preferred embodiment, the sanitization system 10 includes one or more sanitization inserts 18 that are positioned in one or more of the docking stations 16. FIG. 1 shows two different sanitization inserts 18, the first being a sanitizing trolley 20 and the second being a portable sanitizing assembly 22. As shown in FIG. 2, in a preferred embodiment, the sanitizing trolley 20 includes a main body portion 24, wheels 26, a plurality of fixed UV light sources 28, a UV light wand 30, one or more UV light arms 32, a temperature sensor or temperature sensing device 34, a scent mister 36, a controller 38 and a battery 40. It will be appreciated that the UV light arm(s) may also be referred to herein as a UV wand or a movable UV wand. The sanitizing trolley may also include a Bluetooth receiver and/or transponder 39 (e.g., as part of the controller 38 or elsewhere). The galley monument, which the cleaning trolley is installed in, may also include a Bluetooth receiver 41 and/or transponder. As shown in FIG. 1, the portable sanitizing assembly 22 includes a main body portion 24, a plurality of fixed UV light sources 28, a UV light wand 30, a temperature sensing device 34, a scent misting nozzle 36, a controller 38 and a battery 40.

[0029] As shown in FIG. 1, in a preferred embodiment, the monument 12 includes a counter or work deck 42. It will be appreciated that the work deck 42 provides a counter for flight attendants to use during flight. The inserts above the counter are typically smaller than those below the counter. The portable sanitizing assembly 22 is positioned above the counter 42 and the sanitizing trolley 20 is positioned below the counter 42.

[0030] Ultraviolet Light of certain frequencies can kill bacteria and virus. Ultraviolet light between 207 - 222 nm is one such frequency. A wider range of UV light is also within the scope of the present invention (e.g., 265 nm and between 207-265 nm). 207 - 222 nm frequency light has a unique property that it can both kill bacteria and viruses and can be exposed to humans without causing physical harm to the exposed person. 207 - 222 nm light has been shown to kill the COVID 19 corona virus which is living on surfaces. Ultraviolet killing of bacteria and virus is a ‘line of sight’ phenomenon. In other words, only surfaces that are in direct ‘line of sight’ of the light source will be sanitized. In a preferred embodiment, the sanitization inserts 18 include both fixed light sources (e.g., fixed UV light sources 28) and a detachable, movable, repositionable or portable light sources (e.g., UV light wand 30 and UV light arm 32) that both emit light waves between 207 - 222 nm. In use, as the sanitizing trolley 20 or portably sanitizing assembly 22 is moved or carried up and down the aisle, the fixed light sources (e.g., on the sides, front, back, bottom, and potentially top of trolley) kill bacteria and viruses within the ‘line of sight’. Simultaneously, the detachable light sources can be used by the device operator (typically crew member or cleaning crew) to sanitize surfaces that are not in ‘line of sight’ of the fixed light sources. In a preferred embodiment, the sanitizing trolley includes one or more top attach retainers, holder or other containers that can be used to hold cleaning solutions and cleaning wipes. This provides the operator of the sanitizing trolley several methods to clean the cabin and the components therein.

[0031] In a preferred embodiment, the sanitizing trolley 20 includes a misting delivery system (commonly known as a fogger), which includes the nozzle 36 shown in FIGS. 1 and 2. The misting liquid may be a water based solution that is stored within a container in the main body portion 24. Aromatic compounds that are pleasing to the passenger or provide the impression of cleanliness (such as the smell of peppermint) or sanitizing compounds can be added to and included in the misting delivery system. The misting delivery system can deliver these aromatic compounds, or sanitizing compounds, to the floor of the cabin of the aircraft, or other surface. In another embodiment, the invention includes a detachable misting wand through which the misting delivery system dispenses the scent or sanitizer. The detachable misting wand can include a battery, a battery management system, and a misting control device. The battery can be charged in the home galley docking station or can be powered by the battery 40 on the sanitization insert. The operator can then selectively clean surfaces during the flight (cleaning typically high touch areas like lavatory doors) or can selectively place pleasing aromatic compounds into different zones in the aircraft (such as lavatories).

[0032] As discussed above, the sanitizing trolley 20, portable sanitizing assembly 22 or other sanitization insert 18 may include a temperature sensing device 34. The figures show a handheld temperature sensing device. The temperature sensing device can also be incorporated into the main body portion or extend from the sanitization insert 18. The temperature sensing device may send out a temperature sensing signal (e.g., infrared) to determine the temperature of individuals within a predetermined distance of the sanitization insert 18. The temperature sensing device 34 can be used to establish whether the operator, any other tested individual (such as a passenger) or any person within a predetermined distance of the sanitization insert 18 as it moves about the cabin or as a person comes close to the sanitization insert, has a fever. The sanitizing trolley 20 may also be deployed during flight and will be able to indicate if any passenger by location has a fever. The sanitizing trolley 20 (if automated) can then adapt its algorithm to stay close to the zone where the passenger is sitting for a longer period of time or let the operator know the individual has a fever. The sanitizing trolley 20 may also instruct the operator after or during the flight to use the moveable light source to clean the typical touch points of that passenger (tray table, gasper, etc.) that has or had a fever (a temperature above a predetermined point, such as 99°F. This added function provides an enhanced level of protection to the crew that may have been exposed to a virus carried by the passenger or crew.

[0033] In another embodiment, the monument 12 and/or the sanitization inserts 18 can be positioned near or at the entrance of the aircraft. With this positioning the airline crew or ground staff may use the temperature sensing device 34 to measure the temperatures of all the passengers entering the aircraft during boarding. In a similar process they may measure the temperatures of all the passengers leaving the aircraft after the flight is complete. This information can be provided to local health authorities, to make decisions on how to clean the aircraft or can be provided to the sanitizing trolley 20 computer/controller for further uses.

[0034] FIG. 1 shows a galley monument 12 that can be used toward the front and near the entrance of a narrow body aircraft. The monument 12 includes a number of non sanitization inserts that are labeled 44 in the figures. These inserts may be beverage trolleys, coffee makers, ovens, etc. FIG. 3 shows a monument 12 that can be positioned in the aft of a narrow body aircraft and includes a cabin attendant seat 110 and a lavatory 112. FIG. 3 also shows power sources or outlets 46 in some of the insert spaces or docking stations 16. When the sanitization insert 18 is inserted into the docking station 16, the insert is electrically connected to the outlet 46 so that it can be powered as it is docked. For example, the battery on the sanitizing trolley 20 can be recharged while docked.

[0035] As discussed above, government regulators, such as the FAA, have developed procedures, regulations, processes and certification requirements to ensure products that are introduced into aircraft are safe, meet requirements and regulations, are low or sufficient weight, low or sufficient power, and compact in volume. In a preferred embodiment, the sanitization system 10 of the present invention includes a monument 12 that has already been certified by the appropriate governmental agency, such as the FAA or EASA. The certification requirements include power load certification and weight load certification. Accordingly, in a preferred embodiment, the monument 12 includes a monument certified power load limit and a monument certified structural weight limit and the monument has already been certified by the FAA. The monument certified power load limit is the total amount of power load of the monument (i.e., the total power that is allowed to be drawn by all the components of the monument). The monument certified structural weight limit is the total weight of the monument 12 plus any inserts 44. In short, there is a total allowed power load limit and a total weight limit. The power load and weight load of each of the inserts make up a portion or a subset of the total power load and weight load. Therefore, using the example discussed above of a trash compactor, the trash compactor has a certified power load limit and a certified structural weight limit. These certified limits are associated with a specific docking station. It will be appreciated that currently there are certified monuments on aircraft that are currently in service and that include a certified trash compactor thereon. The docking station that the trash compactor is docked in therefore includes certified weight and power load limits. In the present invention, the sanitizing trolley 20 that replaces the trash compactor has to have a power source that has a first power requirement that is equal to or less than the first docking station certified power load limit. Furthermore, the sanitizing trolley 20 has a weight that is equal to or less than the first docking station certified structural weight limit (as dictated by the prior resident of the first docking station, the trash compactor).

[0036] The above-detailed description of embodiments of the disclosure is not intended to be exhaustive or to limit the teachings to the precise form disclosed above. While specific embodiments of and examples for the disclosure are described above for illustrative purposes, various equivalent modifications are possible within the scope of the disclosure, as those skilled in the relevant art will recognize. Further, any specific numbers noted herein are only examples and are not limiting: alternative implementations may employ differing values, measurements or ranges. Any patents and applications and other references noted above, including any that may be listed in accompanying filing papers, are incorporated herein by reference in their entirety.
