Abstract

A multifunction showerhead or hand held showerhead assembly, capable of providing a series of water spray effects. The primary components of the showerhead assembly are a fluid directing valve assembly which includes a pair of generally cup shaped members co-axially mounted with opposing end faces proximate to one another. One of the generally cup shaped members has a bottom surface defining a plurality of fluid flow passageways. When the second member is rotated in opposing relationship to the base of the first member, the fluid flow passageways direct the fluid flow from an orifice in the first member to a pair of outlet passages, or alternatively to a sealed chamber.

Claims

1. A showerhead providing a plurality of spray effects, comprising:

inlet port means for establishing fluid communication with a source of water;

first outlet port means for directing a spray of water with a first spray effect;

second outlet port means for directing a spray of water with a second spray effect;

means for variably restricting the flow of water through the showerhead;

a selector plate means internally contained in said showerhead between said inlet port means and said first and second outlet ports means and oriented generally perpendicular to the flow of water from said inlet port means, for selectively directing water flow to said first and second outlet port means to establish fluid communication with said inlet port means, said selector plate including surface features and a shape which permits water to flow in at least one of three paths of through, around and both through and around the selector plate; and

control ring means manually controlled for positioning said selector plate means to selectively open said first and second outlet port means, whereby any combination of different spray effects can be continuously selected.

2. The showerhead of claim 1, wherein said inlet port means comprises:

a surface defining a fluid chamber, said fluid chamber having an upstream opening for receiving water from said source and also having a downstream opening; and

passageway means, defined by said surface features in said selector plate, for providing fluid communication between said downstream opening and said different outlet port means under the control of said control ring means.

3. The showerhead of claim 2, wherein each of said first and second outlet port means comprises:

a series of outlet passages in fluid communication with said passageway means controllably directing water from said downstream opening in said inlet port means through said passageway means, to none, one or more of said outlet passages; and

a pair of spray means for generating said plurality of spray effects, each of said spray means being in fluid communication with one of said outlet passages.

4. The showerhead of claim 2, wherein said selector plate comprises:

valve sealing means, selectively movable to block said downstream opening portions of said passageway means and to allow communication between said downstream opening of said outlet port means.

5. The showerhead of claim 3 wherein said plurality of spray means comprises:

first spray means for providing a continuous spray; and

second spray means for providing a pulsating spray or continuous spray from said showerhead.

6. The showerhead of claim 5 wherein said continuous spray means comprises:

a face plate in fluid communication with one of said outlet passages, said face plate including a spray ring defining a series of angled bores in constant fluid communication with said one of said outlet passages.

7. The showerhead of claim 5 wherein said pulsating effect means comprises:

a face plate defining a series of discharge passages;

rotor means positioned for rotation adjacent said discharge passages, for interrupting the flow of water through each of said passages; and

channel means, in fluid communication with said discharge passages and one of said outlet passages, for providing a tangential stream of water to said rotor means to impart rotation to said rotor means and to supply water to said discharge passages.

8. A showerhead comprising:

inlet means for establishing fluid communication with a source of water;

first means for directing a spray of water with a first spray effect;

second means for directing a spray of water with a second spray effect;

flow selection means for selectively directing water flow to said first and second means, wherein said flow selection means includes a selector plate internally contained in said showerhead between said inlet means and said first and second means, said selector plate oriented generally perpendicular to the flow of water from said inlet means, said selector plate including an end face having surface features defining at least two alternative fluid flow paths, said surface features including;

first means for defining a first channel having fixed width and depth dimensions;

an O-rings placed in said first channel defined by said first means, said O-rings having a diameter greater than the depth of said first channel;

means for diverting a flow of water constrained within said O-rings to said first means for directing a spray of water;

means for directing a flow of water constrained outside of said O-rings to said second means for directing a spray of water;

second means for defining a second channel having fixed width and depth dimensions, said second means for defining a second channel being disposed about said first means for defining a first channel;

a second O-rings placed in said second channel defined by said second means, said second O-ring having a diameter greater than the depth of said second channel; and

an elevated land disposed between said first O-rings and said second O-ring operative to restrict water flow;

means for allowing manual control of said flow selection means, wherein said means for allowing manual control includes a control ring manually controlled for positioning said selector plate to selectively open said first and second means, whereby any combination of different spray effects can be continuously selected; and

means for variably restricting the flow of water through the showerhead. PG,22

9. The showerhead of claim 8, wherein said inlet means comprises:

a valve body having an end face including an orifice allowing water flow from within said valve body through said orifice, said end face of said valve body positioned facingly opposed to said end face of said selector plate such that said first and second O-rings contact said end face of said valve body.

10. A showerhead comprising:

inlet means for establishing fluid communication with a source of water;

first means for directing a spray of water with a first spray effect;

second means for directing a spray of water with a second spray effect;

flow selection means selectively directing water flow to said first and second means, wherein said flow selection means further includes a selector plate internally contained in said showerhead between said inlet means and said first and second means, said selector plate oriented generally perpendicular to the flow of water from said inlet means, said selector plate includes an end face having surface features defining at least two alternative fluid flow paths;

means for allowing manual control of said flow selection means;

means for interlocking respective components of said showerhead upon assembly to prevent disassembly; and

means for variably restricting the flow of water through the showerhead.

11. A showerhead comprising:

inlet means for establishing fluid communication with a source of water;

first means for directing a spray of water with a first spray effect;

second means for directing a spray of water with a second spray effect;

flow selection means for selectively directing water flow to said first and second means;

means for allowing manual control of said flow selection means;

means for interlocking respective components of said showerhead upon assembly to prevent disassembly; and

an outer spray ring of resilient material defining a plurality of spray ports disposed within said second means for directing a spray of water with a second spray effect.

12. The showerhead of claim 11, further comprising:

an inner spray ring of resilient flexible material disposed within said first means for directing a spray of water with a first spray effect.

13. The showerhead of claim 11, wherein said first means for directing a spray of water with a first spray effect includes a face plate defining a series of discharge passages, and rotor means positioned for rotation adjacent said discharge passages, for interrupting the flow of water through each of said passages.
