Abstract

A showerhead as described herein includes a translucent hollow body having a fluid chamber, and a fluid distribution element configured to release fluid contained in the fluid chamber. The fluid distribution element includes a plurality of raised concentric rings having peaks that serve as the fluid release points. The fluid distribution element contains a number of fluid ducts that are specifically shaped to transport the fluid from the fluid chamber toward the fluid release points. The translucent nature of the showerhead creates an optical lens effect that illuminates the showerhead and the water droplets formed by the showerhead. The illumination of the water droplets creates a pleasant showering experience for the user.

Claims

1. A showerhead comprising:

a showerhead;

a fluid chamber within said showerhead, said fluid chamber being configured to receive fluid;

a fluid distribution element for releasing fluid from said fluid chamber, said fluid distribution element having an interior side facing said fluid chamber and an exterior side opposite said interior side; and

one or more ducts formed within said fluid distribution element, each having an inlet hole for receiving fluid from said fluid chamber, and a groove connected to said inlet hole, said groove being configured to support and transport fluid laterally across said fluid distribution element from said inlet hole toward a fluid release point on said exterior side.

2. A showerhead according to claim 1, wherein said fluid chamber is defined at least in part by said interior side of said fluid distribution element.

3. A showerbead according to claim 1, wherein each of said one or more ducts further comprises a tapered outlet section connected to said inlet hole.

4. A showerhead according to claim 3, wherein said tapered outlet section is also connected to said groove.

5. A showerhead according to claim 4, wherein:

said groove and said tapered outlet section combine to form a duct outlet at said exterior side; and

the area of said duct outlet is greater than the area of said inlet hole.

6. A showerhead according to claim 3, wherein said tapered outlet section has a partial-cone shape.

7. A showerhead according to claim 1, wherein:

said fluid distribution element comprises a number of protrusions on said exterior side; and

said fluid release point corresponding to each of said ducts is located on one of said protrusions.

8. A showerhead according to claim 7, wherein said number of protrusions comprises a plurality of raised and concentric rings.

9. A showerhead element for releasing fluid from a fluid source, said showerhead element comprising

an interior side facing said fluid source and an exterior side opposite said interior side;

and

one or more ducts formed within said showerhead element each having an inlet hole for receiving fluid from said fluid source, and a groove connected to said inlet hole, said groove being configured to support and transport fluid laterally across said showerhead element from said inlet hole toward a fluid release point on said exterior side.

10. A showerhead element according to claim 9, wherein each of said one or more ducts further comprises a tapered outlet section connected to said inlet hole.

11. A showerhead element according to claim 10, wherein said tapered outlet section is also connected to said groove.

12. A showerhead element according to claim 11, wherein:

said groove and said tapered outlet section combine to form a duct outlet at said exterior side; and

the area of said duct outlet is greater than the area of said inlet hole.

13. A showerhead element according to claim 10, wherein said tapered outlet section has a partial-cone shape.

14. A showerhead element according to claim 9, further comprising a number of protrusions on said exterior side, wherein said fluid release point corresponding to each of said ducts is located on one of said protrusions.

15. A showerbead element according to claim 14, wherein said number of protrusions comprises a plurality of raised and concentric rings.

16. A fluid distribution duct formed within a showerhead, said fluid distribution duct comprising:

an inlet hole for receiving fluid; and

a groove connected to said inlet hole, said groove being configured to support and transport fluid laterally from said inlet hole toward a fluid release point on said showerhead.

17. A fluid distribution duct according to claim 16, further comprising a tapered outlet section connected to said inlet hole.

18. A fluid distribution duct according to claim 17, wherein said tapered outlet section is also connected to said groove.

19. A fluid distribution duct according to claim 18, wherein:

said groove and said tapered outlet section combine to form a duct outlet at said exterior side; and

the area of said duct outlet is greater than the area of said inlet hole.

20. A fluid distribution duct according to claim 17, wherein said tapered outlet section has a partial-cone shape.
