DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] An air conditioner energy recovery unit, generally identified by reference numeral 10, will now be described with reference to FIG. 1 through FIG. 9.

[0027] Referring to FIG. 5, an air conditioner energy recovery unit 10 has a hood 12, at least one aperture 13 into which a fan 14 is positioned, a generator 16 and a power storage 18. Air conditioner energy recovery unit 10 is designed to sit atop an air conditioner unit such that wind discharge from an air conditioner unit is sent into hood 12. Referring to FIG. 3, hood 12 has a substantially pyramidal shape with at least three sides 20 meeting at an apex 22. In the embodiments shown in FIG. 1 and FIG. 2, hood 12 has four sides 20 meeting at apex 22. It will be understood by a person skilled in the art that hood 12 may have more or fewer sides than what is shown. Referring to FIG. 9, hood 12 has a hollow interior 24 and an open base 26. Referring to FIG. 6, at least one of sides 20 has an aperture 13 into which a fan 14 is positioned. Fan 14 has a plurality of blades 28 connected to a central rotor 30. It will be understood by a person skilled in the art that the number of blades 28 may affect the ability to rotate rotor 30, however any number of blades 28 may be used. Air passing through aperture 13 and fan 14 causes blades 28 to rotate which in turn cause rotor 30 to rotate. In the embodiment shown in FIG. 5, all four sides 20 of hood 12 have an aperture 13 and a fan 14. In the embodiments shown, aperture 13 and fan 14 are positioned centrally on sides 20. It will be understood by a person skilled in the art that apertures 13 and fans 14 can be positioned anywhere on sides 20, however greater efficiency may be seen when apertures 13 and fans 14 are positioned centrally. A generator 16 is provided in communication with fan 14 such that when blades 28 and rotor 30 rotate, generator 16 creates electricity. Generator 16 is connected to rotor 30. Power storage 18 is provided in communication with generator 16 for storing electricity created by rotation of fan 14. In the embodiment shown, power storage 18 consists of six batteries 32. It will be understood by a person skilled in the art that power storage 18 may have more or fewer batteries 32 or have a different way of providing electricity storage. To regulate voltage levels traveling into power storage 18, a voltage regulator 34 may be positioned between generator 16 and power storage 18.

[0028] In the embodiment shown, fans 14 positioned on each side 20 of hood 12 are connected together in series by an electrical conducting wire 33 such that electricity generated by a first fan 14 in the series travels to a second fan 14 in the series and continues until it reaches the voltage regulator 34 or power storage 18.

[0029] In the embodiments shown in FIG. 9, an inverted pyramid 36 is provided that has four sides 38, a base 40, and an apex 42. It will be understood by a person skilled in the art that inverted pyramid 36 should have at least three sides and that the number of sides 38 of inverted pyramid 36 is equal to the number of sides 20 of substantially pyramid shape of hood 12. In the embodiments shown in FIG. 4 and FIG. 7, inverted pyramid 36 is positioned within hollow interior 24 of hood 12 such that base 40 of inverted pyramid 36 is adjacent the apex 22 of substantially pyramidal shape of hood 12 and apex 42 of inverted pyramid 36 is positioned below base 40 of inverted pyramid 36. Inverted pyramid 36 acts to direct airflow entering hood through open base 26 towards apertures 13 and fans 14. Inverted pyramid also helps to prevent a “dead spot” of trapped air at the peak of hood 12. As can be seen in FIG. 4 and FIG. 7, base 40 of inverted pyramid 36 effectively seals off access to apex 22 of hood 12 from the rest of hollow interior 24. While this makes the system more efficient, it will be understood by a person skilled in the art that inverted pyramid 36 may not completely seal off access to apex 22. An unsealed apex 22 may reduce the effectiveness of airflow from open base 26 through apertures 13 and fans 14 as air may become stagnant at apex 22. In the embodiments shown, base 40 of inverted pyramid 36 aligns with a top 41 of aperture 13 and apex 42 extends downwards towards a bottom 43 of aperture 13. By aligning base 40 with top 41 of aperture 13, air flow may be guided more efficiently towards and through aperture 13 and fan 14. In the embodiment shown in FIG. 4, inverted pyramid 36 is a truncated pyramid. In the embodiment shown in FIG. 2, inverted pyramid 36 has four sides 38. It will be understood by a person skilled in the art that the number of sides 38 of inverted pyramid 36 is dictated by the number of sides 20 of hood 12. In the embodiment shown in FIG. 7, the height of inverted pyramid 36 and length of base 40 of inverted pyramid 36 are equal.

[0030] Referring to FIG. 4, a pocket 44 is positioned on an exterior surface 46 of hood 12. Pocket 44 may house a multi-function meter 48 for measuring the current created by the rotation of fans 28. It will be understood by a person skilled in the art that any suitable voltage indicator may be used.

[0031] Any use herein of any terms describing an interaction between elements is not meant to limit the interaction to direct interaction between the subject elements, and may also include indirect interaction between the elements such as through secondary or intermediary structure unless specifically stated otherwise.

[0032] In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.

[0033] It will be apparent that changes may be made to the illustrative embodiments, while falling within the scope of the invention. As such, the scope of the following claims should not be limited by the preferred embodiments set forth in the examples and drawings described above, but should be given the broadest interpretation consistent with the description as a whole.
