DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in several different forms and should not be construed as limited to the embodiments set forth herein; rather these embodiments are provided so that this disclosure will be through and complete and will fully convey the scope of the invention to those skilled in the art.

[0015] The present invention is adaptable to large or small aircraft of differing designs. The fuselages of the aircraft for which the present invention is useful are typically built around a frame and have an outer shell and an inner shell and house the passengers. The size and style of the aircraft will in part determine which of the embodiments will be used on a particular aircraft.

[0016] In general, this invention provides several embodiments of a system to simplify disinfecting the interior of an aircraft fuselage. A source of disinfecting solution is supplied to the aircraft; plumbing inside of the aircraft fuselage between said inner shell and said outer shell is connected to the disinfecting solution source. Disinfecting solution dispensers are connected to the other end of the plumbing and are located inside of the aircraft for applying disinfecting solution to surfaces to be disinfected. A controller is connected to the disinfecting system for controlling the amount of disinfectant applied throughout the aircraft fuselage.

[0017] In a first embodiment there is provided an inlet port 110 on the outside of the outer shell of the aircraft fuselage 100 that connects to an external disinfecting solution supply, such as a supply truck containing the disinfecting solution. The system includes disinfecting dispenser, outlet dispensing nozzles 120 installed in different locations inside of the aircraft fuselage ventilating system 118 to apply the disinfecting solution. In FIG. 1, there is shown a cross-sectional view of an aircraft fuselage 100 showing the fuselage outer shell 102 and the inner shell 104. In this embodiment there is an inlet port 110 located on the outside of the aircraft fuselage for making a connection to a source of disinfecting solution. Disinfecting solution dispersant nozzles 120 are located inside the existing aircraft ventilation system 118. The inlet port 110 and the dispersing nozzles 120 are connected to each other through the appropriate plumbing 130 that extends between the inner shell 102 and outer shell 104. The plumbing is made of flexible piping and has typical connectors connecting the inlet port 110 and the dispersing nozzles 120 to the plumbing. The disinfecting system is controlled through a controller 106 that may be located at various positions along the route of the plumbing, depending upon the aircraft. Appropriate controls, such as on/off switches, pumps and the like, known to those skilled in the art, are provided in controller 106 to transport the disinfecting solution through the system control the various nozzles and valves associated therewith. When the system is operating the dispersant nozzles 120 apply a mist of disinfecting solution throughout the aircraft fuselage. By way of example, the fuselage 100 shown in FIG. 1 is that of a Fokker having a configuration of four seats across the fuselage interior.

[0018] This embodiment allows the disinfecting solution to be applied throughout the interior of the aircraft without the cleaning crew having to carry hoses and the like throughout the aircraft to dispense the disinfecting solution. The disinfecting solution may be left to air dry. Optionally, as part of the disinfecting system the cleaning crew may use an electrostatic sprayer as an adjunct of the system. The electrostatic sprayer delivers an electric charge to the disinfectant to help the droplets adhere to surfaces.

[0019] There are situations airports may not have available an external source of disinfecting solution. In such situations the aircraft may utilize a built-in holding tank for the disinfecting solution, such as the embodiment shown in FIG. 2. In FIG. 2 there is a shown a cross-sectional view of an aircraft fuselage 200 having an outer shell 202 and an inner shell 204 and illustrating the disinfecting system located within the aircraft fuselage. Holding tank 210 is located within the fuselage 200 and is connected through appropriate plumbing 230 to dispersing nozzles 220 located throughout the inside of the aircraft ventilation system 218. Controls, such as on/off switches, pumps and the like, known to those skilled in the art, are provided in controller 206 to transport the disinfectant and control the various nozzles and valves associated with the system. The embodiment, like the others allows the dispersant mist to be applied throughout the interior of the aircraft without the cleaning crew having to carry hoses and the like throughout the aircraft in order to dispense the disinfectant.

[0020] The disinfecting system of the embodiment shown in FIG. 3 varies somewhat from the embodiments of FIG. 1 and FIG. 2 in that rather than using the existing aircraft ventilation system for supplying disinfecting solution separate nozzles are used. Thus, there is shown in FIG. 3 a cross-sectional view of an aircraft fuselage 300 having an outer shell 302 and an inner shell 304 and illustrating another embodiment of the disinfecting system of the present invention. There is an inlet port 310 located on the outside of aircraft fuselage 300 capable of making a connection to disinfecting solution sourced from outside of the aircraft, typically a service truck. The inlet port 310 and the dispersant nozzles 320 are connected to each other through the appropriate plumbing 330. The system is controlled by controller 306 having appropriate switches, pumps, and the like. The disinfecting solution is pumped through nozzles 320 disperse the disinfecting solution throughout the aircraft fuselage.

[0021] FIG. 4 is a cross-sectional view a further embodiment of the present invention showing an aircraft fuselage 400 having an outer shell 402 and an inner shell 404. There is provided a holding tank 410 located on the inside of aircraft fuselage 400 for holding disinfecting solution. The holding tank 410 is connected through plumbing 430 to dispersing nozzles 420. The system is controlled by controller 406 having appropriate switches, pumps, and the like.

[0022] Many modifications and other embodiments of the invention set forth herein will come to mind to one skilled in the which the invention pertains having the benefit of the teachings presented in the foregoing description. Therefore, it is to be understood that the invention is not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for the purposes of limitation.
