Description
2 FIELD OF THE INVENTION
Tlae present invention relates generally to shower fixtures. More particularly, the -present invention relates to a showerhcad.
BACKGROUND OF THE INVENTION
The prior art is replete with showerhea.d designs. Con~rentional showerheads utilize unmodified free flow water pressure to generate a spray of water. Water exiting a traditional showerhead is sent in a single direction by the force of the water pressure created in the supply plumbing. Such systems tend to consume a substantial amount of fresh water, most of which is wasted. Furthermore, most known showexhcads k produce a relatively narrow shower of water rather than distributing the water over a wide area. Such narrowly focused showerheads do not produce an effective stream of water that efficiently provides a wide area of water coverage to the person taking tf~e shower.
BRIEF SUMMARY OF THE ENVENTION
A showerhead according to the present invention produces an e~cient and effective shower of water in a manner that conserves water. In contrast to many prior art designs, the showcrhcad distributes water over a relatively wide area without relying on wasteful free flow water pressure obtained directly from the supply plumbing.
Certain aspects of the present invention nnay be carried out in one form by a showerhead including a housing having a fluid inlet; a baffle located within the housing, the baffle having a first side, a second side, and a plurality of fluid seep holes, where the first side and at least a portion of the housing defrnc a fluid chamber;
and a fluid distribution element closing the baffle within the housing. The fluid distribution element is configured to release fluid obtained from the fluid seep holes.
A more complete understanding of the present invention may be derived by referring to the detailed description and claizxi.s when considered in conjunction with the following Figures, wherein like reference numbers refer to similar elements throughout the Figures.

DETAILED DESCRiPTIOI~ 4F A PREFERREb ENl>30DIMEhl'f FIG. 1 depicts a shower fixture assembly 100 in operation. In most conventional applications, shower fixture assembly 100 is attacked to a plmanibing feature, e.g., a water pipe 102, that protrudes from a wall x 04. Of course, skzower fixture assembly r 100 may be installed in any number of alternate mounting configurations.
Shower fCxturc assembly 100 includes a showerhead 106 configured io accordance with the present invention. Showerhcad 106 is connected to water pipe 102 via a suitable conduit 108, which may include one or more interconnected pipes, hoses, or the like.
As shown in FIG. J , slzowerhead 106 may be connected to a first end of conduit 108 via an adjustable joint 110, such as a swivel joint, a telescoping joint, a ball joint, or a _ rotating joint. Joint 110 allows the user to adjust the position of showcrhead l Ofi arid, consequently, the direction of the exiting water llaw. Although not a requirement of the present invention, shower fixture assembly 100 may include a flow valve 112 for controlling the flow of fluid entering shower fixture assembly 100. Flow valve may be utilized in conjunction with e~cistxng hot and cold water valves (or a caznbined hot and cold water regulator) to provide an added measure of water flow control.
Shower fixture assembly 100 may include an integral soap dispenser 114 that allows the user to dispense liquid soap and/or soap suds from showerhead 106. For example, 5 soap dispenser 114 may be located between flow valve 112 and conduit 108.
Conduit 108 may include a soap mixing chamber 116 for mixing soap with incoming water.
In operation, soap dispenser 114 is filled or charged (with, for example, a liquid soap product) with flow valve 112 in the closed position. When flow valve 112 is opened, the soap from soap dispenser 114 is mixed with water from water pipe 102.
Mixing chamber 116 may contain a number of in-line perforated baffles 118 (shown in dashed lines) that function to thoroughly mix the soap and water, resulting in an even frothing of suds and a full utilization of the soap product. The perforated baffles 118 may be angled with respect to the axis of mixing chamber 116 to promote efficient and uniform mixing of the soap and water. The soap suds and any remaining soap product can be purged from shower fixture assembly 100 by moving flow valve to the filly opened position.
Although FIG. 1 depicts a top-mounted showerhead 106, the present invention is not so limited. Indeed, the features described below can also be extended for use in connection with a side-mounted showerhead and with other configurations and arrangements that may not be specifically addressed herein.
fIG. 2 is a cross sectional view of a showerhead 200 according to the present invention, and FIG. 3 is an exploded perspective view of showerhead 200. The cross sectional view of FIG. 2 corresponds to a vertical plane through the center of -showerhead 200. Although FIGS. 2 and 3 depict a round showerhead, the present invention is not limited to any spcci~~c shape or size. Showerhead 200 generally iu~cludes a housing 202, a baffle 204, an absorbent element 206, and a fluid =
distribution element 208. Each of these components is described in more detail below.
Housing 202 provides the structural foundation for showerhead ZOU. Idousing 202 can x 0 be formed from stainless steel, aluminum, plastic, or any suitable material. Housing 202 includes an upper lid 210 and a perimeter sidewall 212 extending from upper lid 210. Although not a requirement of the present invention, upper lid 210 and sidewall r 212 may be intel;rally formed as a one~piece unit. In the illustrated erxibadinnent, housing 202 is circular iz~ shape and its height is substantially less than its diameter.
por example, a housing 202 suitable fox a practical application may have a diameter of 12 inches, a one-half inch height, and a one-eighth inch wall thickness.
Housing .
202 includes a fluid inlet 214 formed therein for receiving fluid such as water. In '=
practical applications, fluid inlet 214 is coupled to a joint, a conduit, a pipe, or a suitable fixture that provides water to showcrhead 202 (see, for example, shower 2Q fixture assembly 100)_ The size, shape, andlor location of fluid inlet 214 on showerhead 200 may vary from unit to unit depending upon the desired fluid flow characteristics, fluid chamber size, back pressure specifications, showerhcad size, and r other practical considerations.
Baffle 204 is formed from a substantially rigid material such as stainless steel, aluminum, or plastic. In the example embodiment, baffle 204 ix approximately one-sixteenth of an inch thick, baffle 204 is located within housing 202, and housing 202 t includes struch~re for positioning baffle 204 in the desired mounting location. For example, housing 202 may include an interior shoulder 216 formed within and around r sidevvall 212. Alternatively, housing 2p2 may include a number of discontinuous interior positioning tabs formed within and around sidewall 212. In a practical embodiment, baffle 204 is attached to housing 202 using a suitable mounting technique, e.g., welding, screws, adhesive, r~r the like. Alternatively, bathe 204 may be simply held in place by absorbe~at elertxent 206 andlvr fluid distribution element 208 (i.e., showerhead 200 may employ a sandwich construction technique).
With additional reference to FIG. 4, baffle 204 includes a first side 21$, a second side 220 opposing first side 218, and a plurality of seep holes 222 formed therein.
When baffle 204 is installed in housing 202, first side 218 is oriented upward and second side 220 is oriented downward. First side 218 and at least a portion of housing 202 (e.g., upper lid 2i0 and a portion of sidewall 212) define a fluid chamber 224 configured to receive fluid from fluid inlet 214. In the example embodiment, fluid chamber 224 is contained within housing 202. Housing 2U2 and baffle 204 are sized and shaped such that fluid chamber 224 is relatively flat and thin. I7zis configuration g allows fluid chamber 224 to be quickly ~~lled and pressurized with fluid. In addition, the relatively low volume defined by fluid chamber 224 ensures that water is conserved during operation of showerhead 200. In accordance with one practical example, fluid chamber 224 resembles a cylinder having a 12 inch diameter and a one-eighth inch heist.
Seep holes 222 allow the back pressurized fluid contained in fluid chamber 224 to seep into a second fluid chamber 226 defined by second side 220 ofbaftIe 204, an inner surface 228 of fluid distribution element 208, and portions of sidewall 212. In accordance with one practical example, seep holes 222 are drilled into baffle 204 to a diameter between approxinciately one-sixteenth to approximately one-eighth inclL pf course, seep holes 222 need not be uniform in size or shape, and baffle 204 may include any combination of different seep hole configurations. Far example, seep holes 222 rnay be realized as round holes, elongated slits, cracks, or the like.
Seep holes 222 may be suitably configured in a pattern that generates a dispersed fluid flow over an area of baffle 204. For example, seep hales 222 may be uniformly positioned over the entire surface of baffle 204. Alternatively, a number of seep holes 222 may be concentrated in specific areas of baffle 204, e.g., near the center or near the edge of baffle 204. Furthermore, the site of seep holes 222 may vary depending upon their location on baffle 204. For example, larger diameter seep holes can be located near the outer perimeter of baffle 204, and stx~aller diameter seep holes can be located near the center of baffle 204. The location of seep holes 222 in bafk7e 204 may vary depending upon the size of showerhead 200, the anticipated water pressure auiti=d~~rhr~d~-z~; tti~slr~;:~~~ 4~11'ra~n ~~~iid~irla~3i~sLdba~u~rtuz~; ~z ~-~ . . .. . . .
other practical considerations. Preferably, seep holes 222 are patterned such that the fluid passes into second fluid chamber 226 at a substantially constant flow rate and in an evenly distributed manner.
Showerhead 200 may include a number of baffle offsets 230 located between baffle 20a and upper lid 210 of housing 202. Baffle offsets 230 rnay be realized as small blocks, spherical balls, or the tiko. in one practical embodiment, bale of~'sets 230 are attached to first side 218 of baffle 204 such that, when baffle 204 is installed in housing 202, baffle offsets 230 contact upper lid 210. Baffle offsets 230 reduce flexing ofbaffle 204 and maintain the integrity of first fluid chamber 224.
The relatively small and unobtrusive size of the baffle offsets 230 allows fluid to flow between and around baffle offsets 230 without adversely affecting the seepage from fluid chamber 224 to fluid chamber 22b. a Fluid distribution element 208 is attached to housing 202 such that it forms a lower lid that encloses baffle 204 within housing 202. A practical embodiment utilizes a stainless steel fluid distribution element 208 that is welded to housing 202.
As described above, second fluid chamber 226 is defined in part by inner surface 228 of fluid distribution element 208. In accordance with an example embodiment, second fluid chamber 22G is larger than fluid chamber 224; second fluid chamber 22G
resembles a cylinder having a diameter of 12 inches and a one-quarter inch height. -Absorbent element 206 is suitably positioned within second fluid chamber 226.
In the illustrated embodiment, absorbent clement 20G substantially fills second fluid E
chamber 226. In this regard, absorbent clement 20G is positioned between second side 220 of baffle 204 and inner surface 228 of fluid distribution element 208.
Absorbent element 206 is suitably configured to fluidly couple fluid chamber 224 to fluid distribution element 208. Absorbent element 206 is formed from a fluid-permeable material that allows fluid to be transported from seep holes 222 to fluid distribution -element 208.
in a practical embodiment, absorbent element 206 is formed from a suitable material that does not retain a significant amount of fluid after showerhead 200 is depressurized. In other words, a suitable absorbent element 206 would be self draining to reduce the likelihood of corrosion, mildew, and mold. Although not a requirement of the present invention, absorbent element 20b is substantially uniform in composition throughout second fluid chamber 22G. Such uniformity ensures that fluid is discharged from absorbent element 20G in a consistent and even manxaer. Tn one practical embodimexat, absorbent element 24G is fozmed froze a solid, porous, and dense material.
Absorbent element 206 may be formed from any of the following materials, alone or in combination: foam; nylon webbing; stainless steel mesh; perforated rubber;
natural or synthetic sponge; or the like. Absorbent element 24G may be held in place by fluid distribution ele~nmt 208, or it may be attached to baffle 204, housing 202 andlor fluid distribution element 208. Absorbent element 206 may be fabricated as an individual component or it may be deposited or injected into showerhead 200 during assembly.

FIG. 5 is a bottom view of fluid distribution element 208 and F1G. 6 is a perspective view of a detailed portion of fluid distribution element 208, Lu a practical embodiment, fluid distribution element 208 is formed from a suitable material such as stainless steel, aluminum, plastic, or the like. ~rie~ly, fluid distribution element 208 is w suitably configured to release fluid obtained from seep holes 222 via absorbent element 205. In this regard, fluid disttJ-bution element 208 is fluidly coupled to fluid chamber 22a via seep holes 222, second fluid chamber 226, and absorbent element 20G.
Fluid distribution ole~nent 208 includes at least one fluid release surface 232, a plurality of fluid distribution holes 234 formed within fluid distribution element 208, and a plurality of protrusions 236 extending beyond fluid release surface 232.
Fluid distribution element 208 may be a unitary component that defines protrusions 23G, or it may be a combination of a lid (or a plate) having any number of attached elements that serve as protrusions 236. In this regard, protrusions 236 provide a texturized outer surface for fluid distribution element 208. In one practical embodiment, fluid distribution holes 234 terminate at fluid release surface 232. In lieu of (or in addition to) fluid distribution holes 234, fluid distribution element 208 may be formed from a porous or fluid permeable material that facilitates fluid transfer from second fluid chamber 226.
In the normal operating orientation, water is released at a relative high point, corresponding to fluid release surface 232, before traveling down protrusions 236.
Eventually, the water drops from the relative low points defined by protrusions 236.
As shown in FIG. 6, fluid distribution holes 234 may be located between protrusions 236 such that fluid quickly flows onto protrusions 236.
Protrusions 236 can be sized, shaped, arranged, and otherwise configured to transport fluid away from fluid release surface 232. For example, protrusions 236 can be dome-shaped, pointed, rod-shaped, or the like. Although not a requirement of the present invention, protrusions 236 may be substantially uniform in size and/or substantially uniform in shape. In accordance with one example embodiment, each protrusion is a round bump having a diameter of approximately one-quarter inch and having a height of approximately three-sixteenths of an inch. A number of round holes may be drilled into fluid distribution element 208 to serve as fluid distribution holes 234. In a practical embodiment, fluid distribution holes 234 can have a diameter between approximately one-thirty-second inch and one-eighth inch. Of course, fluid distribution element 20S may include fluid distribution holes 234 of different shapes and sizes. -The creation, of a substantially uniform and distributed back pressure of fluid within second fluid chamber 236, in conjunction with th,e coz~b.guration of fluid distribution element 208, facilitates the even release of fluid droplets across the face of showerhead 200. Relying upon the surface tension of the fluid, the high and low portions of fluid distribution element 208 create "fluid highways" that transport the fluid ~rom holes 234 located above the textured drip point on the face of fluid distribution element 208. The result is the formation of a droplet as the fluid travels from holes 234 to the lower points defined by the ends of protrusions 236. The drops are forced in a relatively slow manner from the face of fluid distribution element 208 by both gravity and by continuing seepage from second fluid chamber 226. This surface tension effect and the formation of droplets is depicted at the left side of FIG.
2. Notably, the droplet size can vary depe~.ding upon the specific texturing of fluid distribution element 208. For instance, larger "bumps" or texturing can generate larger droplets, and smaller "bumps" yr texturing can generate smaller droplets.
Generally, the size and shape of each "bump" in the texture pattern can be designed 2p such that it retains more or less water before releasing the droplet. Irz this regard, ceztain sections of fluid distribution element 20$ can generate relatively small droplets while other sections of fluid distribution element 208 can generate relatively large droplets.
In summary, a shawerhead according to the present invention produces and releases -individual droplets of water using a small amount of water in comparison to traditional showerheads that generate a spray or a stream of water. A
relatively small amount of water is distributed over a large area defined by the fluid distribution E
element. The user experiences a different sensation when the droplets (rather than a spray of water) are released over the wide area. In this regard, the showerhead conserves water while using a new technique for generating and distributing water droplets.
The present invention has been described above with reference to a preferred embodiment. hlowever, those skilled in the art having read this disclosure will recognize that changes and modifications may be made to the preferred embodiment 1 S without departing from the scope of the present invention. These and other changes or modifications are intended to be included within the scope of the present invention, as expressed in the following elaizrAS.

Of course, skzower fixture assembly r 100 may be installed in any number of alternate mounting configurations.
Shower fCxturc assembly 100 includes a showerhead 106 configured io accordance with the present invention. Showerhcad 106 is connected to water pipe 102 via a suitable conduit 108, which may include one or more interconnected pipes, hoses, or the like.
As shown in FIG. J , slzowerhead 106 may be connected to a first end of conduit 108 via an adjustable joint 110, such as a swivel joint, a telescoping joint, a ball joint, or a _ rotating joint. Joint 110 allows the user to adjust the position of showcrhead l Ofi arid, consequently, the direction of the exiting water llaw. Although not a requirement of the present invention, shower fixture assembly 100 may include a flow valve 112 for controlling the flow of fluid entering shower fixture assembly 100. Flow valve may be utilized in conjunction with e~cistxng hot and cold water valves (or a caznbined hot and cold water regulator) to provide an added measure of water flow control.
Shower fixture assembly 100 may include an integral soap dispenser 114 that allows the user to dispense liquid soap and/or soap suds from showerhead 106. For example, 5 soap dispenser 114 may be located between flow valve 112 and conduit 108.
Conduit 108 may include a soap mixing chamber 116 for mixing soap with incoming water.
In operation, soap dispenser 114 is filled or charged (with, for example, a liquid soap product) with flow valve 112 in the closed position. When flow valve 112 is opened, the soap from soap dispenser 114 is mixed with water from water pipe 102.
Mixing chamber 116 may contain a number of in-line perforated baffles 118 (shown in dashed lines) that function to thoroughly mix the soap and water, resulting in an even frothing of suds and a full utilization of the soap product.

The soap suds and any remaining soap product can be purged from shower fixture assembly 100 by moving flow valve to the filly opened position.
Although FIG. 1 depicts a top-mounted showerhead 106, the present invention is not so limited. Indeed, the features described below can also be extended for use in connection with a side-mounted showerhead and with other configurations and arrangements that may not be specifically addressed herein.
fIG. 2 is a cross sectional view of a showerhead 200 according to the present invention, and FIG. 3 is an exploded perspective view of showerhead 200. The cross sectional view of FIG. 2 corresponds to a vertical plane through the center of -showerhead 200. Although FIGS. 2 and 3 depict a round showerhead, the present invention is not limited to any spcci~~c shape or size. Showerhead 200 generally iu~cludes a housing 202, a baffle 204, an absorbent element 206, and a fluid =
distribution element 208. Each of these components is described in more detail below.
Housing 202 provides the structural foundation for showerhead ZOU. Idousing 202 can x 0 be formed from stainless steel, aluminum, plastic, or any suitable material. Housing 202 includes an upper lid 210 and a perimeter sidewall 212 extending from upper lid 210.

por example, a housing 202 suitable fox a practical application may have a diameter of 12 inches, a one-half inch height, and a one-eighth inch wall thickness.
Housing .
202 includes a fluid inlet 214 formed therein for receiving fluid such as water. In '=
practical applications, fluid inlet 214 is coupled to a joint, a conduit, a pipe, or a suitable fixture that provides water to showcrhead 202 (see, for example, shower 2Q fixture assembly 100)_ The size, shape, andlor location of fluid inlet 214 on showerhead 200 may vary from unit to unit depending upon the desired fluid flow characteristics, fluid chamber size, back pressure specifications, showerhcad size, and r other practical considerations.
Baffle 204 is formed from a substantially rigid material such as stainless steel, aluminum, or plastic. In the example embodiment, baffle 204 ix approximately one-sixteenth of an inch thick, baffle 204 is located within housing 202, and housing 202 t includes struch~re for positioning baffle 204 in the desired mounting location. For example, housing 202 may include an interior shoulder 216 formed within and around r sidevvall 212. Alternatively, housing 2p2 may include a number of discontinuous interior positioning tabs formed within and around sidewall 212. In a practical embodiment, baffle 204 is attached to housing 202 using a suitable mounting technique, e.g., welding, screws, adhesive, r~r the like. Alternatively, bathe 204 may be simply held in place by absorbe~at elertxent 206 andlvr fluid distribution element 208 (i.e., showerhead 200 may employ a sandwich construction technique).
With additional reference to FIG. 4, baffle 204 includes a first side 21$, a second side 220 opposing first side 218, and a plurality of seep holes 222 formed therein.
When baffle 204 is installed in housing 202, first side 218 is oriented upward and second side 220 is oriented downward. First side 218 and at least a portion of housing 202 (e.g., upper lid 2i0 and a portion of sidewall 212) define a fluid chamber 224 configured to receive fluid from fluid inlet 214. In the example embodiment, fluid chamber 224 is contained within housing 202. Housing 2U2 and baffle 204 are sized and shaped such that fluid chamber 224 is relatively flat and thin. I7zis configuration g allows fluid chamber 224 to be quickly ~~lled and pressurized with fluid. In addition, the relatively low volume defined by fluid chamber 224 ensures that water is conserved during operation of showerhead 200. In accordance with one practical example, fluid chamber 224 resembles a cylinder having a 12 inch diameter and a one-eighth inch heist.
Seep holes 222 allow the back pressurized fluid contained in fluid chamber 224 to seep into a second fluid chamber 226 defined by second side 220 ofbaftIe 204, an inner surface 228 of fluid distribution element 208, and portions of sidewall 212. In accordance with one practical example, seep holes 222 are drilled into baffle 204 to a diameter between approxinciately one-sixteenth to approximately one-eighth inclL pf course, seep holes 222 need not be uniform in size or shape, and baffle 204 may include any combination of different seep hole configurations. Far example, seep holes 222 rnay be realized as round holes, elongated slits, cracks, or the like.
Seep holes 222 may be suitably configured in a pattern that generates a dispersed fluid flow over an area of baffle 204. For example, seep hales 222 may be uniformly positioned over the entire surface of baffle 204. Alternatively, a number of seep holes 222 may be concentrated in specific areas of baffle 204, e.g., near the center or near the edge of baffle 204. Furthermore, the site of seep holes 222 may vary depending upon their location on baffle 204. For example, larger diameter seep holes can be located near the outer perimeter of baffle 204, and stx~aller diameter seep holes can be located near the center of baffle 204. The location of seep holes 222 in bafk7e 204 may vary depending upon the size of showerhead 200, the anticipated water pressure auiti=d~~rhr~d~-z~; tti~slr~;:~~~ 4~11'ra~n ~~~iid~irla~3i~sLdba~u~rtuz~; ~z ~-~ . . .. . . .
other practical considerations. Preferably, seep holes 222 are patterned such that the fluid passes into second fluid chamber 226 at a substantially constant flow rate and in an evenly distributed manner.
Showerhead 200 may include a number of baffle offsets 230 located between baffle 20a and upper lid 210 of housing 202. Baffle offsets 230 rnay be realized as small blocks, spherical balls, or the tiko. in one practical embodiment, bale of~'sets 230 are attached to first side 218 of baffle 204 such that, when baffle 204 is installed in housing 202, baffle offsets 230 contact upper lid 210. Baffle offsets 230 reduce flexing ofbaffle 204 and maintain the integrity of first fluid chamber 224.
The relatively small and unobtrusive size of the baffle offsets 230 allows fluid to flow between and around baffle offsets 230 without adversely affecting the seepage from fluid chamber 224 to fluid chamber 22b. a Fluid distribution element 208 is attached to housing 202 such that it forms a lower lid that encloses baffle 204 within housing 202. A practical embodiment utilizes a stainless steel fluid distribution element 208 that is welded to housing 202.
As described above, second fluid chamber 226 is defined in part by inner surface 228 of fluid distribution element 208. In accordance with an example embodiment, second fluid chamber 22G is larger than fluid chamber 224; second fluid chamber 22G
resembles a cylinder having a diameter of 12 inches and a one-quarter inch height. -Absorbent element 206 is suitably positioned within second fluid chamber 226.
In the illustrated embodiment, absorbent clement 20G substantially fills second fluid E
chamber 226. In this regard, absorbent clement 20G is positioned between second side 220 of baffle 204 and inner surface 228 of fluid distribution element 208.
Absorbent element 206 is suitably configured to fluidly couple fluid chamber 224 to fluid distribution element 208. Absorbent element 206 is formed from a fluid-permeable material that allows fluid to be transported from seep holes 222 to fluid distribution -element 208.
in a practical embodiment, absorbent element 206 is formed from a suitable material that does not retain a significant amount of fluid after showerhead 200 is depressurized. In other words, a suitable absorbent element 206 would be self draining to reduce the likelihood of corrosion, mildew, and mold. Although not a requirement of the present invention, absorbent element 20b is substantially uniform in composition throughout second fluid chamber 22G. Such uniformity ensures that fluid is discharged from absorbent element 20G in a consistent and even manxaer. Tn one practical embodimexat, absorbent element 24G is fozmed froze a solid, porous, and dense material.
Absorbent element 206 may be formed from any of the following materials, alone or in combination: foam; nylon webbing; stainless steel mesh; perforated rubber;
natural or synthetic sponge; or the like. Absorbent element 24G may be held in place by fluid distribution ele~nmt 208, or it may be attached to baffle 204, housing 202 andlor fluid distribution element 208. Absorbent element 206 may be fabricated as an individual component or it may be deposited or injected into showerhead 200 during assembly.
Y
FIG. 5 is a bottom view of fluid distribution element 208 and F1G. 6 is a perspective view of a detailed portion of fluid distribution element 208, Lu a practical embodiment, fluid distribution element 208 is formed from a suitable material such as stainless steel, aluminum, plastic, or the like. ~rie~ly, fluid distribution element 208 is w suitably configured to release fluid obtained from seep holes 222 via absorbent element 205. In this regard, fluid disttJ-bution element 208 is fluidly coupled to fluid chamber 22a via seep holes 222, second fluid chamber 226, and absorbent element 20G.
Fluid distribution ole~nent 208 includes at least one fluid release surface 232, a plurality of fluid distribution holes 234 formed within fluid distribution element 208, and a plurality of protrusions 236 extending beyond fluid release surface 232.
Fluid distribution element 208 may be a unitary component that defines protrusions 23G, or it may be a combination of a lid (or a plate) having any number of attached elements that serve as protrusions 236. In this regard, protrusions 236 provide a texturized outer surface for fluid distribution element 208. In one practical embodiment, fluid distribution holes 234 terminate at fluid release surface 232. In lieu of (or in addition to) fluid distribution holes 234, fluid distribution element 208 may be formed from a porous or fluid permeable material that facilitates fluid transfer from second fluid chamber 226.
In the normal operating orientation, water is released at a relative high point, corresponding to fluid release surface 232, before traveling down protrusions 236.
Eventually, the water drops from the relative low points defined by protrusions 236.
As shown in FIG. 6, fluid distribution holes 234 may be located between protrusions 236 such that fluid quickly flows onto protrusions 236.
Protrusions 236 can be sized, shaped, arranged, and otherwise configured to transport fluid away from fluid release surface 232. For example, protrusions 236 can be dome-shaped, pointed, rod-shaped, or the like. Although not a requirement of the present invention, protrusions 236 may be substantially uniform in size and/or substantially uniform in shape. In accordance with one example embodiment, each protrusion is a round bump having a diameter of approximately one-quarter inch and having a height of approximately three-sixteenths of an inch. A number of round holes may be drilled into fluid distribution element 208 to serve as fluid distribution holes 234. In a practical embodiment, fluid distribution holes 234 can have a diameter between approximately one-thirty-second inch and one-eighth inch. Of course, fluid distribution element 20S may include fluid distribution holes 234 of different shapes and sizes. -The creation, of a substantially uniform and distributed back pressure of fluid within second fluid chamber 236, in conjunction with th,e coz~b.guration of fluid distribution element 208, facilitates the even release of fluid droplets across the face of showerhead 200. Relying upon the surface tension of the fluid, the high and low portions of fluid distribution element 208 create "fluid highways" that transport the fluid ~rom holes 234 located above the textured drip point on the face of fluid distribution element 208. The result is the formation of a droplet as the fluid travels from holes 234 to the lower points defined by the ends of protrusions 236. The drops are forced in a relatively slow manner from the face of fluid distribution element 208 by both gravity and by continuing seepage from second fluid chamber 226. This surface tension effect and the formation of droplets is depicted at the left side of FIG.
2. Notably, the droplet size can vary depe~.ding upon the specific texturing of fluid distribution element 208. For instance, larger "bumps" or texturing can generate larger droplets, and smaller "bumps" yr texturing can generate smaller droplets.
Generally, the size and shape of each "bump" in the texture pattern can be designed 2p such that it retains more or less water before releasing the droplet. Irz this regard, ceztain sections of fluid distribution element 20$ can generate relatively small droplets while other sections of fluid distribution element 208 can generate relatively large droplets.
In summary, a shawerhead according to the present invention produces and releases -individual droplets of water using a small amount of water in comparison to traditional showerheads that generate a spray or a stream of water. A
relatively small amount of water is distributed over a large area defined by the fluid distribution E
element. The user experiences a different sensation when the droplets (rather than a spray of water) are released over the wide area. In this regard, the showerhead conserves water while using a new technique for generating and distributing water droplets.
The present invention has been described above with reference to a preferred embodiment. hlowever, those skilled in the art having read this disclosure will recognize that changes and modifications may be made to the preferred embodiment 1 S without departing from the scope of the present invention. These and other changes or modifications are intended to be included within the scope of the present invention, as expressed in the following elaizrAS.
