Description
- This invention relates generally to supply of warm air to passengers on aircraft, and more particularly concerns an improved apparatus to be installed in aircraft and having an elongated flexible warm air delivery hose extending from an air heating unit, the hose manipulable to deliver air throughout a wide range of nozzle positions.
- There is need for apparatus, as referred to, as for example in aircraft lavatories, to be used as in hand and or hair drying.
- It is a major object of the invention to provide apparatus, as referred to, to be installed to fixed structure in an aircraft, as for example a panel in an aircraft lavatory, or a panel associated with an aircraft seat, or seats. Basically, the needed and improved apparatus comprises:
- a) a heater and blower unit to be attached to said aircraft fixed structure,
- b) an elongated flexible hose extending from said unit, and configured to receive a flow of heated air from said unit,
- c) a nozzle at a distal end of said hose to direct heated air at a person using said apparatus,
- d) and a retainer for releasably retaining the hose proximate fixed structure at a location remote from the heater and blower unit.
- It is another object of the invention to provide apparatus which can be easily installed to or in association with a panel at or near the top of an aircraft lavatory compartment, so that the downwardly extending hose is immediately useful, throughout the lavatory compartment. As will be seen, a proximity sensor may be installed at or near the nozzle, and operatively connected to the unit to effect activation of the unit in response to release of the nozzle from the retainer.
- A further object is to provide apparatus which can be easily installed to or in association with a panel located at an aircraft seat assembly, as for example beneath a seat part such as an arm rest. In that configuration, the air heater and blower unit can be located beneath the panel, so that the hose may extend remotely and upwardly, for example.
- Yet another object is to provide multiple of such panels on or associated with aircraft seat assemblies, together with multiple of the heater/blower units, hoses and nozzles, enabling warm air delivery to multiple seated passengers. In this regard, a single heater/blower unit can be employed to supply warm air to multiple hoses positioned for passenger use.
- These and other object and advantages of the invention, as well as the details of an illustrative embodiment, will be more fully understood form the following specification and drawings, in which:
- FIG. 1 is an elevation partly broken away to show interior construction of a heater/blower unit to be employed;
- FIG. 2 is a vertical section taken through an aircraft lavatory compartment, to show installation of a heater/blower unit to an upper panel, with an air delivery hose extending downwardly to a nozzle; FIG. 2a is a circuit diagram; and
- FIG. 3 is a vertical section taken through two adjacent lavatory compartments in an aircraft, and showing supply of warm air from a single heater/blower unit to two hoses respectively in the two compartments.
- FIG. 4 is a vertical elevation showing installation of a heater/blower unit to an aircraft passenger seat assembly, with an air delivery hose extending upwardly adjacent a seat back;
- FIG. 5 is a top plan view showing a single heater/blower unit configured to supply warm air to multiple hoses associated with multiple aircraft seats; and
- FIG. 6 is a view like FIG. 5, but showing the structure in elevation.
- In FIG. 1, the highly compact heater and
blower unit 10 includes a cylindrical casing 11 carrying atubular duct 12.Fasteners 13 andvibration absorbing spacers 14 extend between 11 and 12. Arotary impeller 15 is located at the airflow entrance end 12 a of the duct, and anelectrical motor 16 is located downstream of the impeller, and is connected at 18 with the impeller shaft 15 a to drive the impeller. Air is displaced by the impeller blades 15 b to pass in cooling relation with annularly spacedmounting vanes 19 extending radially from themotor casing 20 to theduct 12. - Air flow passes to the right, into contact with the electrical
resistance heating elements 21 extending axially as shown, whereby the air is heated to controlled comfortable temperature. For safety reasons, no surface temperatures, including the surfaces of the heater elements, exceed 300° F. The components ofunit 10 are designed and configured to protect against over/under voltage, over-current, and over-temperature conditions. Heated air flow passes to the rightward,discharge end 22 of the unit, and a convergently tapering baffle 24 reduces the flow area at 25, thereby increasing the flow velocity, for flow in ahose 26. - Referring now to FIG. 2,
unit 10 is shown as installed above an aircraft lavatory interiorupper panel 30, located in thespace 31 between theceiling panel 30 and theaircraft fuselage wall 33. The lavatory interior may include asink 32toilet 34,shelf 35,wall 36, andservice components 37, such as towels supplied at 38,disposal bin 39, etc. - An elongated
flexible hose 26 extends or hangs downwardly from the discharge end of theunit 10, entering the interior of the lavatory via asmall aperture 40 inpanel 30. The hose may include anozzle 41 provided at or proximate a lower end of the hose, for manual manipulation to direct heated air at a passenger holding the nozzle.Hose 26 may also be resiliently stretchable to thereby allownozzle 41 to be positioned to or into a wide area of the lavatory interior, for various drying or heating uses by an interior, for various drying or heating uses by an occupant. For example, a three foot flexible hose can be resiliently stretchable over 100%, i.e. to over 6 feet length. - A retainer is provided for releasably retaining the hose proximate fixed structure at a location remote from said heater and blower unit. See for
example retainer 44 attached to lavatoryfixed wall 45, for retaining thenozzle 41 to that wall, with thehose 26 retained in substantially vertical position, above the nozzle.Retainer 44 may take the form of a C-shaped clip, or other retaining shape. Whennozzle 41 is manually released from the clip, aproximity sensor 100 such as a control switch activates the flow of electrical current flow tounit 10 and viacircuitry - FIG. 3 shows two aircraft lavatory structures or
components 56, each like the structure shown in FIG. 2, the two structures extending adjacent one another, as shown. See adjacent walls 51, separating the two lavatory interiors.Hoses 26 extend downwardly within each compartment, as previously described. - The heater/
blower unit 100, likeunit 10, supplies heated air to each of the hoses, as via a dual outlet manifold 55 associated with the flow discharge end of theduct 12 inunit 100. Valving in the manifold controls flow to thehose 26 to be supplied with warm air; for example the valve to hose entrance end may be opened, as by a solenoid actuator, when the nozzle of that hose is released from its retainer. Accordingly, theunit 100 serves two hoses, singly or simultaneously, in separate lavatories. - FIG. 4 shows attachment of the
unit 10 to a panel 60 associated with an aircraft seat assembly 60 a. That panel faces downwardly, and theunit 10 located beneath that panel. For example, panel 60 may be located at the under side of theaircraft seat 61, with the discharge end ofunit 10 directed rearwardly.Hose 26 is shown extending rearwardly and then upwardly at the rear side of the seat back 63, and theretainer 44 is attached to the back, and retains thenozzle 41 as shown, so that upon freeing of the nozzle from the retainer the hose can be manipulated, directed, and/or stretched, to direct warm air at a passenger seated at seat assembly 60 b, rearwardly of forward seat back 63. - FIG. 6 is like FIG. 4 but showing a
single unit 10 for supplying heated air flow tomultiple hoses 26 extending upwardly from manifolds 26 b (supplied with heated air from unit 10) tomultiple nozzles 41. See also FIG. 5. - In this embodiment, the
unit 10 discharges air forwardly to the manifold that extends laterally beneath the seats, 61 a in a row. Thehoses 26 connect to that manifold. Hoses and nozzles thereby provide air to the passengers in the next rearward seats, and oneunit 10 is enabled to supply air to the multiple nozzles. Valving may be provided, as in FIG. 3, to selectively control air flow to a selected hose, when its nozzle is released from its retainer.
