AIRCRAFT GALLEY WITH INTEGRATED AIR IONIZER

FIELD CROSS-REFERENCE TO RELATED APPLICATIONS

The This application claims priority to, and the benefit of, India Provisional Patent Application No. 20/234,1073227, filed Oct. 27, 2023 and titled “AIRCRAFT GALLEY WITH INTEGRATED AIR IONIZER,” which is incorporated by reference herein in its entirety for all purposes.

FIELD

The present disclosure generally relates to systems for managing air quality in an aircraft, and more specifically, to using air ionizers in an aircraft.

BACKGROUND

Travel within aircraft includes the recirculation of air within the aircraft. Circulation of air within an enclosed space, such as aircraft, may include circulation of harmful pathogens (e.g., viruses, bacteria, etc.) and undesirable odors. Currently, commercial aircraft use air filters, including high efficiency particulate air (HEPA) filters, to filter the air during recirculation. Generally, air filters are placed at central locations and therefore may not have continuous effectiveness within the enclosed space. Furthermore, more effective air filters, such as HEPA filters, come with an increased cost both in terms of the filter itself as well as the energy used to force air through the air filter. Furthermore, air filters, including HEPA filters, tend to not remove odors from the air within the enclosed space.

In various embodiments, aircraft 100 also includes various cabin sections, including, for example, a first cabin section 118, a second cabin section 120, a third cabin section 122, and a pilot cabin 124. In various embodiments, aircraft 100 may include a front galley 126 and/or a rear galley 128.

Referring now to FIGS. 2A and 2B, a galley 200 is illustrated, in accordance with various embodiments. In various embodiments, the galley 200 may be an example of the front galley 126 or the rear galley 128 of FIG. 1. FIG. 2A illustrates a front view of the galley 200. FIG. 2B illustrates a rear view of the galley 200. In various embodiments, the galley 200 may include a plurality of stowage bins 202, a preparation area 204, a trash receptacle 206, one or more galley carts 208, an air outlet 210, ion emitters 212, an air inlet 214, an air duct 216 coupled to air inlet 214 and air outlet 210, and a control unit 218. In various embodiments, the ion emitters 212 may be mounted on a side wall proximate the preparation area 204, adjacent the air outlet 210, within the air outlet 210, or at an outlet of the air outlet 210. In various embodiments, the ion emitters 212 may be mounted within the air outlet 210. In various embodiments, the ion emitters 212 generate ionized air particles, including negative ions 220 and positive ions 222, that are spread throughout the galley 200 by air flow from the air outlet 210.

In various embodiments, the ion emitters 212, and more specifically, the positive ions 222 may neutralize pathogens (e.g., bacteria, viruses, molds, dust, etc.) and/or malodor (i.e., unpleasant smells) that are airborne and on surfaces. Pathogens and malodor may be generated and/or spread by the plurality of stowage bins 202, the preparation area 204, the trash receptacle 206, and the one or more galley carts 208, among other locations. Pathogens and malodor may be airborne and/or settle on surfaces within the galley 200, including the plurality of stowage bins 202, the preparation area 204, the trash receptacle 206, and the one or more galley carts 208, among others.

As illustrated in FIGS. 2A and 2B, the ion emitters 212 may be placed adjacent the air outlet 210 so that the ion emitters 212 ionizes the air exiting the air outlet 210. Generally, ions created by the ion emitters 212, such as the negative ions 220 and the positive ions 222, have an active life span of about 30 seconds to about 75 seconds, and more specifically, about 45 seconds to about 60 seconds. Accordingly, locating the ion emitters 212 adjacent the air outlet 210 improves the efficacy of the negative ions 220 and the positive ions 222 as compared to placing an air ionizer within ductwork of an air handling system or adjacent an air filter within the air handling system. In various embodiments, the ion emitters 212 may be placed inside the air outlet 210, and more specifically, within the ductwork behind the air outlet 210 and immediately adjacent the air outlet 210. In various embodiments, the ion emitters 212 may be incorporated into the air outlet 210 so the ion emitters 212 and the air outlet 210 operate as a single unit to ionize and disperse air throughout the galley 200.

In various embodiments, the galley 200 further includes the control unit 218 that is operatively and electrically coupled to the ion emitters 212 by one or more wires 224. In various embodiments, the control unit 218 controls each of the ion emitters 212 by adjusting a voltage, a current, a timing, and/or other parameters to increase or decrease a number of ions produced by each of the ion emitters 212. In various embodiments, increasing a voltage and/or a current to each of the ion emitters 212 increases the number of ions produced by the ion emitters 212. In various embodiments, decreasing the voltage and/or the current to each of the ion emitters 212 decreases the number of ions produced by the ion emitters 212. In various embodiments, the control unit 218 may control each of the ion emitters 212 individually and/or as all together. In various embodiments, the control unit 218 may step up a received alternating current (AC) or a direct current (DC) voltage to a high voltage for use by the ion emitters 212. In various embodiments, the control unit 218 may be connected to a 115 V AC power source. In various embodiments, the control unit 218 may be connected to a 28 V DC power source. In various embodiments, the control unit 218 may output about 2.5 KV to about 12.5 KV, and more specifically, about 5 KV to about 10 KV.

In various embodiments, the control unit 218 may comprise one or more processors configured to implement various logical operations in response to execution of instructions, for example, instructions stored on a non-transitory, tangible, computer-readable medium. The one or more processors can be a general-purpose processor, a microprocessor, a microcontroller, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, discrete or transistor logic, discrete hardware components, or any combination thereof. In various embodiments, the control unit 218 may further comprise memory to store data, executable instructions, system program instructions, and/or controller instructions to implement the control logic of the control unit 218.

In various embodiments, each of the four of the ion emitters 412 may extend orthogonal to the inner diameter of the air outlet 410 so that each of the ion emitters 412 extends perpendicular to the air flow exiting the air outlet 410. In various embodiments, each of the ion emitters 412 may extend inward from the inner diameter at different non-perpendicular angles, such as angle a illustrated in FIG. 4A. In various embodiments, the ion emitters 412 may be positioned equidistant from each other, as illustrated in FIG. 4A. In various embodiments, the spacing between ion emitters 412 may be non-uniform.

FIG. 4B illustrates three ion emitters 412 disposed radially around an inner diameter of air outlet 410 of air duct 416. In various embodiments, each of the three ion emitters 412 may extend orthogonal to the inner diameter of the air outlet 410 so that each of the ion emitters 412 extends perpendicular to the air flow exiting the air outlet 410. In various embodiments, each ion emitters 412 may extend inward from the inner diameter at different angles. In various embodiments, each of the three ion emitters 412 may be positioned equidistant from each other. In various embodiments, the spacing between one or more of ion emitters 412 may be non-uniform.

FIG. 4C illustrates two of the ion emitters 412 disposed radially around an inner diameter of air outlet 410 of air duct 416. In various embodiments, both ion emitters 412 may extend orthogonal to the inner diameter of air outlet 410 so that each ion emitters 412 extends perpendicular to the air flow exiting the air outlet 410.

Referring now to FIG. 5, a graphical user interface, GUI 500, for controlling one or more air ionizers is illustrated, in accordance with various embodiments. In various embodiments, GUI 500 may communicate with control unit 218, 318. In various embodiments, the one or more air ionizers may be examples of ion emitters 212, 312, 412 described above in FIGS. 2A, 3A, 4A, 4B, and 4C. It should be appreciated that GUI 500 as described below is not intended to be limiting, but to be exemplary one implementation of a user interface for controlling one or more air ionizers and is for case of discussion. As such, GUI 500 may be presented differently and/or provide more or less functionality than what is discussed below.

GUI 500 includes an options menu 502, a cabin area selector 505, a scene selector 506, a current scene indicator 508, an all-areas button 510, a start button 512, a hold button 514, a resume button 516, and a timer 518. Options menu 502 provides a crew member the ability to control different aspects of the cabin including lighting, temperature, windows, and ion count and to view status of the cabin including attendant call button and water status. Cabin area selector 504 allow the crew member to select which cabin section to monitor such as business class, economy class forward, and economy class aft. Pressing all areas button 510 may select all cabin areas for adjustment.

Selecting ion count 520 presents the crew member with scene selector 506 and current scene indicator 508. In various embodiments, scene selector 506 may present the crew member with different scenes to adjust the number of ions being generated by air ionizers and ion emitters (e.g., ion emitters 212, 312, 412) within each cabin area. As illustrated, scene selector 506 presents the cabin crew with different options such as “Boarding/Deplane”, “Take off/Landing”, “Take off/Landing Night”, “High”, “High-Mid”, “Mid”, “Mid-Low”, “Low”, “Waterfall”, “Mountain”, “Seaside”, “Countryside”, “Custom1”, “Custom2”, and “Custom3”. The selections in scene selector 506 are intended to simplify the control of the air ionizers for the cabin crew. As illustrated, the different scenes may produce different numbers of ions depending on the current state of the cabin area. For example, the cabin crew may select “Countryside” or “Low” in response to normal conditions within the cabin area. The cabin crew may select “High” or “Waterfall” in response to a malodor within the cabin area (e.g., a beverage maker, garbage, etc.). Doing so provides the cabin crew the ability to adjust the number of ions per cubic centimeter (ions/cc) per unit time to a level that is comfortable for the passengers by increasing or decreasing the voltage supplied to each ion emitter (e.g., ion emitters 212, 312, 412).

Start button 512 may change the selected scene. Hold button 514 may pause the selected scene for a time. Resume button 516 may resume the selected scene after being on hold. Timer 518 may provide an indication of how long the selected scene has been running or on hold. In various embodiments, GUI 500 may be used to control ion output in each galley independently from other gallies. That is, a first scene may be selected for a first galley and a second scene may be selected for a second galley. This allows for individual control of the different gallies based on the use of each galley.

Referring now to FIG. 6, a system 600 for controlling one or more air ionizers is illustrated, in accordance with various embodiments. System 600 includes a graphical user interface (GUI) 602, a controller 604, and ion emitters 606a-606c. In various embodiments, GUI 602 may be an example of GUI 400 described above in FIG. 4.

Memory 610 is configured to store data from GUI 602 and processor 608. Voltage converter 612 is configured to receive commands from processor 608 and convert an input voltage (e.g., 28 VDC, 115 VAC) to a high voltage output (e.g., 10 kV DC) for use by ion emitters 606a-606c).

Processor 608 may comprise one or more processors configured to implement various logical operations in response to execution of instructions, for example, instructions stored on a non-transitory, tangible, computer-readable medium. The one or more processors can be a general-purpose processor, a microprocessor, a microcontroller, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, discrete or transistor logic, discrete hardware components, or any combination thereof. Memory 610 may comprise memory to store data, executable instructions, system program instructions, and/or controller instructions to implement the control logic of processor 608.

System program instructions and/or controller instructions may be loaded onto a non-transitory, tangible computer-readable medium having instructions stored thereon that, in response to execution by a controller, cause the controller to perform various operations. The term “non-transitory” is to be understood to remove only propagating transitory signals per se from the claim scope and does not relinquish rights to all standard computer-readable media that are not only propagating transitory signals per se. Stated another way, the meaning of the term “non-transitory computer-readable medium” and “non-transitory computer-readable storage medium” should be construed to exclude only those types of transitory computer-readable media which were found in In Re Nuijten to fall outside the scope of patentable subject matter under 35 U.S.C. § 101.
