Description

Technical Field

[0001] The present invention generally relates to disinfection systems, and more specifically to disinfection systems and devices for aircraft.

Background Art

[0002] In the era of the pandemic, it is of utmost importance to monitor the surface contamination by pathogenic microorganisms (such as viruses or bacteria). Disinfection of frequently contacted surfaces such as the surfaces inside an aircraft is as necessary as disinfecting body parts in order to suppress the pandemic without interrupting international trade and travel. Since pathogenic microorganisms can maintain their activity on the surface for several days, rapid spread of infection becomes possible. Pathogenic microorganisms include, for example, coronavirus, Ebola virus, Nipah virus, Salmonella typhi, Mycobacterium tuberculosis, etc. Local outbreaks of epidemics such as COVID-19 may spread domestically or internationally with a higher probability through air travel. In such outbreaks, air travel is severely restricted, causing social and economic damage to each country.

[0003] Ultraviolet (UV) light waves with a wavelength range of 100 nanometers (nm) to 280 nm are inherently bactericidal. The bactericidal wavelength range of UV corresponds to short-wavelength UV, also known as UV-C. Since inexpensive and energy-efficient UV-C light-emitting diodes (LEDs) have been developed, UV-C has been used for the sterilization of surfaces, water, or air.

[0004] In the state-of-the-art technology at present, there are technologies for using UV-C light to disinfect surfaces. However, the existing technologies do not provide an overall disinfection system and are limited to some surfaces and enclosures inside the aircraft, such as galleys, air ducts, aircraft cabins, lavatories, etc. Furthermore, with this technology, it is necessary to keep passengers or crew away for surface disinfection using UV light. Surfaces such as trays, handles of overhead storage bins, and handles of lavatories are frequently contacted by multiple passengers and crew during flights.

[0005] Therefore, in order to suppress the spread of pathogenic microorganisms inside the aircraft, there is a need for a system and device for disinfecting the surfaces of the aircraft at frequent time intervals during flight.

Best Mode for Carrying Out the Invention

[0012] Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. For convenience, the same reference numbers are used throughout the drawings to refer to the same or similar components. This specification describes examples and features of the disclosed principles, but appropriate modifications, adaptations, and other applications are possible without departing from the spirit and scope of the disclosed embodiments. The following detailed description is intended to be considered as illustrative only, and the true scope and spirit of the present invention are defined based on the description in the appended claims. Additional exemplary embodiments are as described below.

[0013] FIG. 1 is an explanatory diagram illustrating an aircraft cabin 100 that can adopt various embodiments. The aircraft cabin 100 can include a plurality of passenger seats (e.g., passenger seat 102a, passenger seat 102b, passenger seat 104a, and passenger seat 104b), a plurality of overhead storage bins (e.g., overhead storage bin 106), and a lavatory 110. Each of the plurality of passenger seats can include a safety belt (e.g., safety belt 112). In one embodiment, passenger seat 102a can include an armrest 114a, and passenger seat 102b can include an armrest 114b. Each of armrest 114a and armrest 114b can include a pocket (e.g., pocket 116), a tray (e.g., tray 118), and an upper lid (e.g., upper lid 120). When the tray is enclosed within the pocket, the pocket can be configured to store the tray, and the upper lid can be configured to cover the pocket. Further, the tray can be in an open state or a closed state. The tray is at least partially located outside the pocket in the open state and completely located inside the pocket in the closed state. In passenger seat 102a, tray 118 is in the open state, and in passenger seat 102b, the tray is in the closed state and covered by upper lid 120. This is as will be described in more detail later in relation to FIG. 5.

[0014] The passenger seat 104a can include a back. A frame (e.g., frame 122) can be attached to the back. Further, a tray (e.g., tray 124a or tray 124b) can be operatively coupled to at least first two corner portions of the frame, such that the tray is rotatable about a pivot axis (not shown in FIG. 1). The tray can be in an unlocked state, in which the tray forms an angle greater than zero with respect to the frame. Alternatively, the tray can be in a locked state, in which the tray forms an angle equal to zero with respect to the frame. That is, the tray is in full contact with the frame. Further, a latch (not shown in FIG. 1) can be provided to cooperate or engage with the tray. For this purpose, the tray can include a recess, cavity or protrusion in which the latch can engage in the locked state. In the unlocked state, the latch can disengage from the tray. Tray 124a is in the unlocked state and tray 124b is in the locked state. This will be described in more detail later in connection with FIG. 4.

[0015] The passenger seats each include a safety belt, e.g., a seat belt 112 The safety belt can include a first portion attached to the first fabric portion thereof and a second portion attached to the second fabric portion of the safety belt. The first portion can be configured, for example, as a female portion of a buckle used to secure the seat belt. Also, the second portion can be configured, for example, as a male portion of the buckle. That is, the first portion is configured to receive the second portion for securing the safety belt. This will be described in more detail later in connection with FIGS. 2 and 3. Also, the plurality of overhead storage bins can each include a handle (e.g., handle 126a or handle 126b). Also, the dressing room 110 can include a handle 128.

[0016] Needless to say, contact of body parts (such as fingers, hands, arms, elbows, etc.) with various aircraft surfaces during flight is assumed. As an example, aircraft surfaces include, but are not limited to, safety belt 112, tray 118, trays 124a and 124b, handles 126a and 126b, and handle 128. Also, body parts can be a source of contamination. Infectious diseases can be transmitted if at least one of the aircraft surfaces is contaminated. As an example, infectious diseases include, but are not limited to, coronavirus disease (COVID-19), Ebola virus disease, H1N1 infection, Nipah virus infection, Salmonella infection, tuberculosis, etc. Therefore, each surface of the aircraft may need to be regularly disinfected even during flight.

[0017] For this purpose, multiple sets of ultraviolet (UV) light-emitting diodes (LEDs) can be installed in various locations of the aircraft cabin 100. The multiple sets of UV LEDs can be configured to disinfect each surface of the aircraft. Needless to say, light in the UV wavelength range is bactericidal. By exposing to UV light for a predetermined threshold time, each surface of the aircraft can be disinfected. However, since ultraviolet rays are carcinogenic, it may be necessary to avoid exposure to the human body. Therefore, it is desirable to perform disinfection of each surface of the aircraft by UV light when there are no passengers or crew on board the aircraft or in a state of being isolated from exposure to the human body during the flight of the aircraft. This will be described in detail later in relation to FIGS. 2 to 10.

[0018] FIG. 2 is a series of explanatory diagrams illustrating an aircraft disinfection system 200 according to an embodiment for disinfecting a first portion 202 of a safety belt. The safety belt can be the safety belt 112 in the aircraft cabin 100. The series of explanatory diagrams of the aircraft disinfection system 200 are a perspective view 204a, a perspective view 204b, a top view 204c, a side view 204d, and a front view 204e. The aircraft disinfection system 200 can include a first portion 202 of the safety belt (e.g., the female part of the buckle) attached to a first fabric portion 206 of the safety belt (e.g., safety belt 112). The safety belt can include a second portion (not shown in FIG. 2, e.g., the male part of the buckle) attached to a second fabric portion of the safety belt (not shown in FIG. 2). The first portion 202 is configured to receive the second portion to fix the safety belt. The second portion and the second fabric portion of the safety belt are as described in detail later in relation to FIG. 3. The perspective view 204a shows the first portion 202 and the first fabric portion 206 of the safety belt. The aircraft disinfection system 200 can further include a first storage casing 208. The first storage casing 208 is configured to completely enclose the first portion 202 for disinfecting it.

[0019] The first storage casing 208 can include a first inner wall 210, a first set of UV LEDs 212, and a tong 214. The first inner wall 210 can be configured to surround the first outer surface. Further, the first set of UV LEDs 212 can be attached to the first inner wall 210. The first set of UV LEDs 212 can be configured to disinfect the outer surface of the first portion 202. In some embodiments, the first set of UV LEDs 212 can include at least one UV-C LED. Further, the tong 214 can be configured to cooperate with the first portion 202 of the safety belt 112. The perspective view 204b shows the cooperation relationship between the tong 214 and the first portion 202. In the perspective view 204b, when the insertion of the first portion 202 into the first storage casing 208 is completed, the tong 214By lifting the flap 202a, it is possible to disinfect the inner wall of the flap 202a in the first part 202 (not shown in FIG. 2) and the area of the first part 202 that was not covered by the flap 202a before lifting. The tongs 214 can be fixed within the first storage casing 208 and can be at least partially disposed inside the first part 202. In another embodiment, the tongs 214 can be completely disposed inside the first part 202.

[0020] The tongs 214 can have a second set of UV LEDs 216 attached to each of its surfaces. The second set of UV LEDs 216 is shown in the front view 204e. The second set of UV LEDs 216 can be configured to disinfect the inner surface of the first part 202. In one embodiment, the second set of UV LEDs 216 can disinfect the inner wall (not shown in FIG. 2). In some embodiments, the second set of UV LEDs 216 can include at least one UV-C LED. The top view 204c shows the first part 202 surrounded by the first storage casing 208. The side view 204d shows the cooperation between the tongs 214 and the first part 202. Also, the front view 204e shows the first part 202 surrounded by the first storage casing 208.

[0021] In some embodiments, the first storage casing 208 includes a first slit 218 (shown in side view 204d) for receiving the first fabric portion 206. The first slit 218 can include a first pair of rollers (not shown in FIG. 2) for cooperating with the first fabric portion 206. That is, after passing through the first slit 218, the first fabric portion 206 is fixed or attached to the first portion 202. The first pair of rollers confines the first portion 202 by sliding the first storage casing 208 over the first fabric portion 206. As described above, the first fabric portion 206 passes through the first storage casing 208 via the first slit 218. In one embodiment, the first storage casing 208 can include a first electric mechanism (not shown in FIG. 2) coupled to the first pair of rollers. The first electric mechanism can be configured to slide the first storage casing 208 over the first fabric portion 206 by operating the first pair of rollers. The first electric mechanism can be constituted by, for example, an electric motor.

[0022] The aircraft disinfection system 200 can further include a first set of sensors (not shown in FIG. 2) within the first storage casing 208. The first set of sensors can be configured to determine the complete confinement of the first portion 202. As an example, the first set of sensors can include, but is not limited to, proximity sensors, cameras, ultrasonic sensors, etc. Further, the aircraft disinfection system 200 can include a controller (not shown in FIG. 2) communicatively connected to each of the first set of UV LEDs 212, the second set of UV LEDs 216, the first set of sensors, and the first electrification mechanism.

[0023] The controller can be configured to respond to a disinfection execution signal, give an instruction to the first electric mechanism to slide on the first cloth portion 206, thereby enclosing 208 that wraps the first storage casing. The disinfection execution signal can be generated, for example, when the crew and passengers disembark from the aircraft and no one is on board the aircraft. Alternatively, the disinfection execution signal can be generated when the second portion of the safety belt is not inserted into the first portion 202. That is, the disinfection execution signal can be generated when the male part of the safety belt buckle is removed from the female part of the safety belt buckle.

[0024] Furthermore, the controller can be configured to activate each of the first set of UV LEDs 212 and the second set of UV LEDs 216 in response to a first set of sensors that confirm the complete enclosure of the first portion 202 by the first storage case. After a predetermined period has elapsed since the activation of the first set of UV LEDs 212 and the second set of UV LEDs 216, the controller can be configured to give an instruction to the first electric mechanism to slide on the first cloth portion 206, thereby exposing the first storage casing 208. In some embodiments, the controller can be configured to deactivate the first set of UV LEDs 212 and the second set of UV LEDs 216 in response to confirmation of partial enclosure of the first set of sensors. In other words, if someone tries to pull out the first portion 202 currently enclosed in the first storage casing 208, the controller can deactivate the first set of UV LEDs 212 and the second set of UV LEDs 216. The controller can be configured to deactivate the first set of UV LEDs 212 and the second set of UV LEDs 216 respectively when any movement is detected by the first set of sensors. As will be apparent to those skilled in the art, the aircraft disinfection system 200 is not limited to aircraft and can be applied to trains, buses, passenger cars, trucks or any vehicle. The aircraft disinfection system 200 can also be applied to public facilities such as movie theaters and malls.

[0025] FIG. 3 is a series of explanatory diagrams illustrating an aircraft disinfection system 300 according to an embodiment for disinfecting a second portion 302 of a safety belt. The safety belt can be the safety belt 112 of the aircraft cabin 100. The series of explanatory diagrams showing the aircraft disinfection system 300 are a perspective view 304a, a top view 304b, a front view 304c, and a side view 304d. The perspective view 304a shows the second portion 302 attached to the second fabric portion 306 of the safety belt. Further, the aircraft disinfection system 300 can include a second storage casing 308 for surrounding the second portion 302. The second storage casing 308 can include a second inner wall 310 and a third set of UV LEDs 312. The inner wall 310 can be configured to surround the second portion 302. The third set of UV LEDs 312 can be attached to the second inner wall 310. The third set of UV LEDs 312 is configured to disinfect the second portion 302. In some embodiments, the third set of UV LEDs 312 can include at least one UV-C LED.

[0026] In some embodiments, the second storage casing 308 includes a second slit 314 (shown in the side view 304d) configured to receive the second fabric portion 306. That is, the second fabric portion 306 passes through the second slit and is attached to the second portion. Further, the second slit 314 can include a second pair of rollers (not shown in FIG. 3) for cooperating with the second fabric portion 306. That is, the second pair of rollers enables the second storage casing 308 to slide on the second fabric portion 306 to enclose the second second portion 302. The second fabric portion 306 passes through the second storage casing 308 via the second slit 314. In one embodiment, the second storage casing 308 can include an electric mechanism (not shown in FIG. 3) coupled to the second pair of rollers. The second electric mechanism can be configured to slide the second storage casing 308 on the second fabric portion 306 by operating the second pair of rollers. The second electric mechanism can be composed of, for example, an electric motor.

[0027] The aircraft disinfection system 300 can further include a second set of sensors (not shown in FIG. 3) within the second storage casing 308. The second set of sensors can be configured to determine complete containment of the second portion by the second storage casing 308. As an example, the second set of sensors can include, but is not limited to, proximity sensors, cameras, ultrasonic sensors, etc. The aircraft disinfection system 300 can include a controller (not shown in FIG. 3) communicatively connected to each of the third set of UV LEDs 312, the second set of sensors, and the second electric mechanism. The controller can be configured to give an instruction to the second electric mechanism to slide on the second cloth portion 306 in response to the disinfection execution signal described in detail in FIG. 2, thereby containing the second storage casing 308.

[0028] Furthermore, the controller can be configured to activate a third set of UV LEDs 312 in response to a second set of sensors that determine a complete containment of the second portion 302 by the second housing 308. The controller can be configured to give an instruction to the second motor mechanism after a predetermined period has elapsed to slide on the second fabric component 306, thereby exposing the second housing 308. In some embodiments, the controller can be configured to deactivate the third set of UV LEDs 312 in response to a second set of sensors that determine a partial containment of the second portion 302 by the second housing 308. That is, if someone attempts to pull out the second portion 302 currently contained by the second housing 308, the controller can deactivate the third set of UV LEDs 312. Also, the controller can be configured to deactivate the third set of UV LEDs 312 when the second set of sensors detect any movement. As will be apparent to those skilled in the art, the aircraft disinfection system 300 is not limited to aircraft and can also be applied to trains, buses, passenger cars, trucks, or any vehicle. The aircraft disinfection system 300 can also be applied to public use facilities, such as movie theaters and malls.

[0029] FIG. 4 is a series of explanatory diagrams illustrating an aircraft disinfection system 400 according to an embodiment for disinfecting a tray 402. This series of explanatory diagrams includes a perspective view 404a, a top view 404b, a front view 404c, a top view 404d, a front view 404e, a side view 404f in the closed state, and a side view 404g in the open state. The aircraft disinfection system 400 can include a frame 406 and a tray 402. In one embodiment, the frame 406 can be attached to the back of a passenger seat (e.g., passenger seat 104a) in the aircraft cabin 100. In other embodiments, the frame can be attached to the cabin wall of the aircraft.

[0030] The tray 402 can be operably coupled to at least the first two corner portions (e.g., corner portions 406a and 406b) of the frame 406 and can be rotatable about a pivot axis 408 (intersecting the corners 406a and 406b). The tray 402 can be configured to be in a locked state and / or an unlocked state based on rotation about the pivot axis 408. The tray 402 forms an angle greater than zero with respect to the frame 406 in the unlocked state and an angle equal to zero with respect to the frame 406 in the locked state. The tray 402 is shown in the unlocked state in each of the top view 404d, the front view 404e, and the side view 404f. The tray 402 is shown in the unlocked state in each of the perspective view 404a, the top view 404b, the front view 404c, and the side view 404g.

[0031] The aircraft disinfection system 400 can further include a set of UV LEDs 410 attached to the exposed surface of the frame 402. The tray 402 can face the exposed surface of the frame 402 in the locked state. The set of UV LEDs 410 can be configured to disinfect the tray 402 when the tray 402 is in the locked state. In some embodiments, the set of UV LEDs 410 can include at least one UV-C LED. The frame 406 can include at least one switch (e.g., switch 412a and switch 412b) disposed on the outer periphery of the frame 406. The tray 402 can be configured to enclose each of the at least one switch in the locked state. The frame 406 can also include a latch 414 for cooperating with the tray 402. The latch 414 can engage with the tray 402 in the locked state and can be released from the tray 402 in the unlocked state. For this purpose, the tray 402 can include a recess, a cavity, or a protrusion for engaging the latch 414 in the locked state.

[0032] Frame 406 can include a controller communicatively connected to at least one switch and latch 414. The controller can be configured to activate a set of UV LEDs 410 when a set of predetermined conditions are met. The set of conditions can include that the trays 402 are each in a locked state, that at least one switch is turned on, and that the latch 414 engages the tray 402. In some embodiments, frame 406 can include at least one sensor for generating an inactivate signal based on a predetermined criterion. As an example, the predetermined criterion can be a transition of the tray 402 from a locked state to an unlocked state. As another example, the predetermined criterion can be the detection of some movement or a human body part. The controller can be communicatively connected to the at least one sensor. Thus, the controller can be configured to deactivate the set of UV LEDs 410 in response to an inactivate signal generated by the at least one sensor. The at least one sensor can be disposed on the outer periphery of the frame 406 and can be enclosed by the tray 402 in the locked state. As will be apparent to those skilled in the art, the aircraft disinfection system 400 is not limited to aircraft and can also be applied to trains, buses, passenger cars, trucks or any vehicle. The aircraft disinfection system 400 can also be applied to public use facilities, such as movie theaters and malls.

[0033] FIG. 5 is a series of explanatory diagrams illustrating an aircraft disinfection system 500 according to another embodiment for disinfecting a tray 502. These series of explanatory diagrams are a perspective view 504a, a perspective view 504b, a front view 504c, and a side view 504d. The aircraft disinfection system 500 can include an armrest 506 of a passenger seat. As an example, the passenger seat is the passenger seat 102a in the aircraft cabin 100. The armrest 506 can include a pocket 508 and an upper lid 510. The pocket 508 can be configured to store a tray.

[0058] As can be further understood by those skilled in the art, current disinfection systems lack a mechanism to effectively disinfect the surfaces of an aircraft on which passengers and crew are boarding. The technologies described above are for disinfecting the surfaces of an aircraft. In particular, the technologies described above are for disinfecting the surfaces of an aircraft via multiple sets of UV LEDs. According to the technologies described above, surfaces such as trays, door handles in the lavatory, or handles on overhead storage bins can be disinfected while passengers and crew are boarding. The technologies described above provide an effective means to prevent exposure of ultraviolet rays to the body parts of users. Surfaces such as the locking part of a seatbelt can be disinfected before and after a flight when passengers and crew are not boarding. The technologies described above provide an enclosure composed of a storage casing for storing the locking part of a seatbelt, a frame and pockets for storing trays, or a curved enclosure for covering a handle. Each set of UV LEDs is mounted inside such an enclosure. Further, the technologies described above use sensors to detect the presence of the body parts of users inside the enclosure. The sensors activate the UV LEDs in a closed or locked state of the surface to prevent exposure of UV light radiation to the body parts of users. The technologies described above can be applied to air ducts of the air conditioning system inside an aircraft, the inside of the lavatory, the inside of the aircraft cabin, handheld devices (e.g., in-flight entertainment controllers), etc.
