The frame itself includes an exterior face having a plurality of openings formed therein so as to permit air flow therethrough from the vent and provide an attractive exterior appearance. Furthermore, rotatably connected to the frame is at least one propeller assembly having a central hub and at least one blade extending from a perimeter of the central hub. The propeller assembly is structured to freely rotate as a result of air flow from the air conditioning duct flowing thereover, such that the air flow is dispersed and more evenly distributed into the room as it passes from the propeller assembly through the exterior face of the frame. In addition to evenly dispersing the air flow, the propeller assembly is equipped to distribute an air freshener into the air flow such that it will circulate into the room and provide it with a pleasant aroma. ## Claims ### Claim 1 To be disposed over an outlet vent of an air conditioner duct, an air conditioner vent cover assembly comprising: a frame, said frame being structured for secure, fitted engagement over the outlet vent, said frame including an exterior face having a plurality of openings formed therein so as to permit air flow therethrough from the vent, at least one propeller assembly, said propeller assembly including a central hub and at least one blade extending from a perimeter of said central hub, said central hub being generally perpendicularly disposed to said exterior face of said frame and to a direction of flow of said air flow, rotation means connected between a central axis of said propeller assembly and said frame and structured to permit the free rotation of said propeller assembly as a result of air flow from said air conditioning duct flowing over said propeller assembly such that said air flow is dispersed as it passes from said propeller assembly through said exterior face of said frame to more evenly affect an area into which the outlet vent extends, and scent dispersement means structured and disposed to disperse an air freshener into said air flow upon passage of said air flow therethrough. ### Claim 2 (depends on 1) An air conditioner vent cover assembly as recited in claim 1 wherein said rotation means includes a central shaft extending from said central hub at said central axis of said propeller assembly. ### Claim 3 (depends on 2) An air conditioner vent cover assembly as recited in claim 2 wherein said central shaft includes a distal end structured to be rotatably positioned within a bearing seat mounted to said frame so as to provide for friction minimizing, free rotation of said central shaft and therefore said propeller assembly. ### Claim 4 (depends on 3) An air conditioner vent cover assembly as recited in claim 3 wherein said bearing seat is mounted on said exterior face of said frame such that a force of said air flow on said propeller assembly tends to maintain said central shaft within said bearing seat. ### Claim 5 (depends on 1) An air conditioner vent cover assembly as recited in claim 1 including two of said propeller assemblies disposed a spaced apart distance from one another and rotatably secured to said frame by said rotation means. ### Claim 6 (depends on 1) An air conditioner vent cover assembly as recited in claim 1 further including scent dispersement means structured and disposed to disperse an air freshener into said air flow upon passage of said air flow therethrough. ### Claim 7 (depends on 6) An air conditioner vent cover assembly as recited in claim 6 wherein said scent dispersement means include a housing defining an interior compartment, and including a plurality of flow through passages formed therein and structured to permit air flow through said interior compartment. ### Claim 8 (depends on 7) An air conditioner vent cover assembly as recited in claim 7 wherein said scent dispersement means further includes an air freshener impregnated medium structured to be contained within said interior compartment of said housing so as to release a quantity of said air freshener into said air flow passing thereover. ### Claim 9 (depends on 8) An air conditioner vent cover assembly as recited in claim 8 wherein said air freshener impregnated medium includes a liquid soaked sponge. ### Claim 10 (depends on 7) An air conditioner vent cover assembly as recited in claim 7 wherein said housing is secured to an outer face of said exterior face of said frame. ### Claim 11 To be disposed over an outlet vent of an air conditioner duct, an air conditioner vent cover assembly comprising: a frame, said frame being structured for secure, fitted engagement over the outlet vent, said frame including an exterior face having a plurality of openings formed therein so as to permit air flow therethrough from the vent, at least one propeller assembly, said propeller assembly including a central hub and at least one blade extending from a perimeter of said central hub, rotation means connected between a central axis of said propeller assembly and said frame and structured to permit the free rotation of said propeller assembly as a result of air flow from said air conditioning duct flowing over said propeller assembly such that said air flow is dispersed as it passes from said propeller assembly through said exterior face of said frame to more evenly affect an area into which the outlet vent extends, said central hub being generally perpendicularly disposed to said exterior face of said frame and to a direction of flow of said air flow, and scent dispersement means structured and disposed to disperse an air freshener into said air flow upon passage of said air flow therethrough. ### Claim 12 (depends on 11) An air conditioner vent cover assembly as recited in claim 11 wherein said scent dispersement means include a housing defining an interior compartment, and including a plurality of flow through passages formed therein and structured to permit air flow through said interior compartment. ### Claim 13 (depends on 12) An air conditioner vent cover assembly as recited in claim 12 wherein said housing is secured to an outer face of said exterior face of said frame so as to facilitate access to said interior compartment. ### Claim 14 (depends on 13) An air conditioner vent cover assembly as recited in claim 13 wherein said scent dispersement means further includes an air freshener impregnated medium structured to be contained within said interior compartment of said housing so as to release a quantity of said air freshener into said air flow passing thereover. ### Claim 15 (depends on 11) An air conditioner vent cover assembly as recited in claim 11 wherein said rotation means includes a central shaft extending from said central hub at said central axis of said propeller assembly. ### Claim 16 (depends on 15) An air conditioner vent cover assembly as recited in claim 15 wherein said central shaft includes a distal end structured to be rotatably positioned within a bearing seat mounted to said frame so as to provide for friction minimizing, free rotation of said central shaft and therefore said propeller assembly. ### Claim 17 (depends on 16) An air conditioner vent cover assembly as recited in claim 16 wherein said bearing seat is mounted on said exterior face of said frame such that a force of said air flow on said propeller assembly tends to maintain said central shaft within said bearing seat. ### Claim 18 (depends on 11) An air conditioner vent cover assembly as recited in claim 11 including two of said propeller assemblies disposed a spaced apart distance from one another and rotatably secured to said frame by said rotation means.
