[0031] With reference now to the drawings, and in particular to FIGS. 1 through 4 thereof, a new portable air conditioner embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

[0032] As best illustrated in FIGS. 1 through 4, the portable air conditioner 10 generally comprises an insulated housing 11, in the shape of a box wherein a bottom portion 12 of the housing extends downwardly in the shape of a frustum. The housing can be made from any insulating material, however polystyrene is preferred due to its light weight. A lid 13 is in a top side 15 of the housing. An intake portal 14 is on the first side 28 of the housing and is substantially adjacent to the top side of the housing. A first tube 16 is in fluid connection with the intake portal and extends into the housing. The first tube extends perpendicular to the first side of the housing. The first tube arcs away from the lid. A discharge portal 17 is on a second side 18 of the housing. The second side is parallel to the first side of the housing. The discharge portal is substantially adjacent to the top side of the housing. A second tube 19 extends into the housing whereby the second tube is in fluid connection with the discharge portal. The second tube extends perpendicular to the second side of the housing and gradually arcs away from the lid.

[0033] A bar 20 is mounted to a bottom side 21 of the top portion 15 of the housing. The mounting is comprised of two elongate members 22, 23 extending downwardly from opposite sides of the bottom side of the top portion. The mountings are adapted to allow the bar to rotate on an axial center line. The bar extends from the intake portal 14 to the discharge portal 17. A first propeller 24 is attached to the first end 25 of the bar. The first propeller is angled to draw air into the housing. A second propeller 26 is attached to second end 27 of the bar. The second propeller is angled to pull air from the housing.

[0034] A gear housing 30 contains a first gear 31 and a second gear 32. The first gear is coupled to the bar through a bore 33 in the gear. The second gear is coupled to an electric motor 34. The motor is mounted to the housing and, as it is coupled to the second gear, it holds the second gear in place. The first gear and the second gear are coupled together by a belt 35. The housing and the mounting for the bar hold the first gear in place. Preferably, the motor is located at a tip of the frustum 12. Preferably, a battery 37 is operationally coupled to the motor. Also preferably, a switch 38 is located adjacent to the battery and is operationally coupled thereto to turn the motor off and on.

[0035] A drain 39 is located adjacent to the motor. Preferably the draining means comprises a bore in the housing and a pin 40 adapted to be removably placed in the bore.

[0036] A duct 50 is affixed to the discharge portal 17 and extends away from the housing. Preferably, the duct has a flexible portion 51 thereon for directing airflow.

[0037] Two straps 52, 53 are attached a third side (not shown) of the housing.

[0038] Optionally, the portable unit can come with a stand 60. The stand being adapted to hold the portable air conditioner. The stand being rectangular in shape wherein each of the corners of the stand has a leg 61 extending downwardly therefrom. The stand has two sets 62, 63 of parallel upwardly extending walls. One set of parallel walls 63 has a third strap 65 attached therebetween for carrying the stand.

[0039] In use, the lid 13 is opened and ice 66 is placed inside of the housing. The switch 38 is turned on which activates the motor 34. The power supply is ideally a battery pack 37, but another embodiment, not shown, would utilize a conventional power supply comprising a plug and standard home outlet with a motor adapted for AC current. The motor turns the bottom gear 32 and a belt 35 attached to it turns the top gear 31 . The top gear is coupled to the bar 20 which rotates causing the propellers 24, 26 to turn. The action of the first propeller 24 draws air into the housing. The second propeller 26 is not necessary but is preferably included, as it will push the air out of the housing at a greater velocity than if the first propeller were working alone. The air is drawn over the ice 66 that cools it down. The cool air leaves through the discharge portal 17 and enters the duct 50. The duct is fitted with a portion 51 that is bendable to allow the user to direct the cool air in any direction. The housing has straps 52, 53 attached to it to allow users to wear the unit on their backs. Optionally, a stand 60 comes with the unit to allow the user to sit the unit down next to them such as for use in a tent. A drainage pin 40 allows excess water to be removed from the unit.

[0040] As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

[0041] With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

[0042] Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
