Abstract

An air diffuser for distributing air into a room from a supply duct of an air distribution system having: a frame member, wherein the frame member includes an inner surface, and an outer surface; an attachment member, wherein the attachment member is associated with the frame member, and further wherein the attachment member is configured for associating the air diffuser with a supply duct; and a diffusing member, wherein the diffusing member comprises a substantially hemispherical dome having an inner surface, an outer surface, and a plurality of apertures, and wherein the substantially hemispherical dome emanates away from the outer surface of the frame member.

Claims

1. An air diffuser for distributing air into a room from a supply duct of an air distribution system, comprising:

a frame member, wherein the frame member comprises an inner surface, and an outer surface;

an attachment member, wherein the attachment comprises an upper end and a lower end, and wherein the upper end of the attachment member is secured to the supply duct of the air distribution system, and wherein the lower end of the attachment member is secured to the frame member, and wherein the attachment member facilitates fluid communication from the supply duct of the air distribution system to the diffusing member;

a diffusing member, wherein the diffusing member comprises a substantially hemispherical dome having an inner surface, an outer surface, and a plurality of apertures, and wherein the substantially hemispherical dome emanates away from the outer surface of the frame member and further wherein the diffusing member comprises an outer rim; and

an annular support member, wherein the annular support member at least partially covers the inner surface of the diffusing member along at least a portion of the outer rim.

2. The air diffuser according to claim 1, wherein at least a majority of the plurality of apertures comprise a circular geometry.

3. The air diffuser according to claim 1, wherein the plurality of apertures consist of a circular geometry.

4. The air diffuser according to claim 1, wherein at least 40% of the total surface area of the substantially hemispherical dome comprises the plurality of apertures.

5. The air diffuser according to claim 1, wherein at least 50% of the total surface area of the substantially hemispherical dome comprises the plurality of apertures.

6. The air diffuser according to claim 1, wherein at least 60% of the total surface area of the substantially hemispherical dome comprises the plurality of apertures.

7. The air diffuser according to claim 1, wherein at least 70% of the total surface area of the substantially hemispherical dome comprises the plurality of apertures.

8. The air diffuser according to claim 1, wherein the substantially hemispherical dome comprises a plurality of evenly distributed apertures.

9. The air diffuser according to claim 1, wherein the frame member further comprises an aperture for containing the diffusing member.

10. The air diffuser according to claim 9, wherein the diffusing member further comprises an outer rim, and wherein the outer surface of the diffusing member contacts the inner surface of the frame member along at least a portion of the outer rim.

11. The air diffuser according to claim 10, wherein the support member, the diffuser member, and the frame member are fixedly attached together.

12. The air diffuser according to claim 1, wherein the frame member and the diffuser member comprise a unitary member.

13. The air diffuser according to claim 1, wherein at least two of the frame member, the diffuser member, a support member, and the attachment member comprise a unitary member.

14. The air diffuser according to claim 1, wherein the air diffuser facilitates substantially even distribution of air throughout an associated room.

15. The air diffuser according to claim 1, wherein the air diffuser substantially reduces drafts during operation of an associated air distribution system.

16. The air diffuser according to claim 1, wherein the air diffuser substantially reduces a temperature gradient in an associated room.

17. An air diffuser for distributing air into a room from a supply duct of an air distribution system, comprising:

a frame member, wherein the frame member comprises an inner surface, an outer surface, and an aperture;

an attachment member, wherein the attachment member comprises an upper end and a lower end, and wherein the upper end of the attachment member is secured to the supply duct of the air distribution system, and wherein the lower end of the attachment member is secured to the frame member, and wherein the attachment member facilitates fluid communication from the supply duct of the air distribution system to the diffusing member; and

a diffusing member, wherein the diffusing member comprises a substantially hemispherical dome having an inner surface, an outer surface, and a plurality of apertures, wherein at least a majority of the plurality of apertures comprise a circular geometry, and further wherein the substantially hemispherical dome emanates away from the outer surface of the frame member, and further wherein the diffusing member comprises an outer rim, and wherein the outer surface of the diffusing member contacts the inner surface of the frame member along at least a portion of the outer rim; and

further wherein the inner surface of the diffusing member is at least partially covered with an annular support member along at least a portion of the outer rim; and

further wherein at least 40% of the total surface area of the substantially hemispherical dome comprises the plurality of apertures.

18. An air diffuser for distributing air into a room from a supply duct of an air distribution system, comprising:

a frame member, wherein the frame member comprises an inner surface, an outer surface, and an aperture;

an attachment member, wherein the attachment member comprises an upper end and a lower end, and wherein the upper end of the attachment member is secured to the supply duct of the air distribution system, and wherein the lower end of the attachment member is secured to the frame member, and wherein the attachment member facilitates fluid communication from the supply duct of the air distribution system to the diffusing member; and

a diffusing member, wherein the diffusing member comprises a substantially hemispherical dome having an inner surface, an outer surface, and a plurality of apertures, wherein the substantially hemispherical dome emanates away from the outer surface of the frame member, and further wherein the diffusing member comprises an outer rim, and wherein the outer surface of the diffusing member contacts the inner surface of the frame member along at least a portion of the outer rim; and

further wherein the inner surface of the diffusing member is at least partially covered with an annular support member along at least a portion of the outer rim.
