Abstract

Showerheads with two or more nozzles configured to deliver water streams that converge at one or more regions. Prior to convergence, the converging water streams may generally retain a recognizable shape determined by the type of nozzle. Upon convergence, at least portions of the converging water streams may substantially disperse into multiple individual water droplets. The nozzles, or a face plate or other components joining the nozzles to a showerhead, may be selectively movable to selectively move the region or regions of convergence closer to or further away from the showerhead, or to convert the nozzles from delivering converging streams to delivering non-converging streams or vice versa. Some showerheads may further include other nozzles for delivering water from the showerhead in other modes, such a high pressure mode, a pulsating mode, a mist mode, and so on.

Claims

1. A showerhead comprising:

a water inlet;

a showerhead face;

a plurality of water channels in fluid communication with the water inlet; and

a plurality of nozzles each of which is in direct fluid communication with a respective one of the plurality of water channels and operatively associated with the showerhead face, wherein

at least two of the plurality of nozzles are configured to direct coherent water streams exiting the at least two of the plurality of nozzles to converge in at least one convergence region at a distance from the showerhead face to substantially break apart the coherent water streams and convert the coherent water streams into a cloud-like region of multiple water droplets.

2. The showerhead of claim 1, wherein the distance of each convergence region is approximately five inches or less from the showerhead face.

3. The showerhead of claim 1, wherein water streams having a common convergence region have a substantially similar shape.

4. The showerhead of claim 3, wherein the shape is selected from the group consisting of a fan, flat, conical, partially conical, helical, or cruciform shaped water stream.

5. The showerhead of claim 1, wherein water streams having a common convergence region have a substantially similar flow rate.

6. The showerhead of claim 1, further comprising a body defining the plurality of water channels for fluidly joining the water inlet to the plurality of nozzles.

7. The showerhead of claim 1, further comprising a showerhead coupling assembly selectively operatively associated with the water inlet.

8. The showerhead of claim 7, wherein the showerhead coupling assembly comprises a ball joint member pivotally connected to a coupling member.

9. The showerhead of claim 8, wherein selectively operatively associating the showerhead coupling assembly with the water inlet comprises selectively joining the coupling member to the water inlet.

10. The showerhead of claim 1, further comprising a threaded portion proximate the water inlet.

11. The showerhead of claim 1, wherein the showerhead includes at least two modes of operation.

12. The showerhead of claim 11, wherein at least one of the two modes of operation comprises delivering water streams from the at least two of the plurality of nozzles.

13. The showerhead of claim 12, wherein at least one other of the two modes of operation comprises delivering a pulsating stream from the plurality of nozzles.

14. The showerhead of claim 1, wherein the at least two of the plurality of nozzles includes at least five nozzles configured such that water streams existing the at least five nozzles converge at a common convergence region to substantially convert at least portions of the water streams from the at least five nozzles into multiple water droplets.

15. The showerhead of claim 1, wherein at least one of the at least one convergence region is selectively movable relative to the showerhead.

16. The showerhead of claim 15, further comprising a flexible face plate selectively movable from at least a first position to a second position, the at least two nozzles joined to the flexible face plate, wherein moving the at least one selectively movable convergence region comprises moving the showerhead plate from a first position to a second position.

17. The showerhead of claim 1 further comprising an adjustment device operable to conjointly adjust positions of the at least two of the plurality of nozzles to thereby adjust an angle of the coherent water streams and thus a location of the convergence region.

18. The showerhead of claim 17, wherein

the nozzles are pivotably connected to the showerhead face,

the adjustment device comprises a cam rotatably connected to the showerhead face,

the cam comprising a plurality of cam slots, each cam slot engaged with one of the plurality of nozzles, and

when the cam rotates with respect to the showerhead face, a movement of the cam slots cause the plurality of nozzles to pivot with respect to the showerhead face.

19. The showerhead of claim 17, wherein

the showerhead face further comprises a flexible faceplate upon which the at least two of the plurality of nozzles are mounted;

and

the adjustment device adjusts the flexible faceplate between a substantially flat form and an outwardly convex form to conjointly adjust an angle of convergence of the coherent water streams.

20. The showerhead of claim 1 wherein the at least two of the plurality of nozzles each have unitary body that further defines a nozzle intake oath taken by water that enters the nozzle and nozzle outlet path taken by water that exits the nozzle, wherein the nozzle intake path is substantially parallel to a centerline of the water inlet and the nozzle outlet path is angled with respect to the centerline of the water inlet, and the angle of the nozzle outlet path determines an exit angle of the coherent water streams with respect to the showerhead face and thus a location of the convergence region.

21. The showerhead of claim 20, wherein a first diameter of the outlet path is smaller on the outlet side than a second diameter of the outlet path on the inlet side.

22. The showerhead of claim 1, further comprising an intermediate chamber fluidly connected between the water inlet and the plurality of water channels.

23. The showerhead of claim 1, wherein the at least two of the plurality of nozzles each have a unitary body that further defines a nozzle intake path taken by water that enters the nozzle and an internal nozzle path taken by water inside the nozzle, wherein the nozzle intake path is substantially parallel to a centerline of the water inlet and the internal nozzle path is curved with respect to the nozzle intake path, and a curvature of the internal nozzle paths creates an exit angle of the coherent water streams with respect to the showerhead face and thus a location of the convergence region.

24. The showerhead of claim 1, wherein all of the plurality of nozzles are configured to direct coherent water streams exiting the at least two of the plurality of nozzles to converge in at least one convergence region at a distance from the showerhead face to substantially break apart the coherent water streams and convert the coherent water streams into a cloud-like region of multiple water droplets.
