DETAILED DESCRIPTION OF THE INVENTION

(11) The present invention addresses the aforementioned disadvantages by providing an improved showerhead assembly. While the showerhead assembly is susceptible of embodiment in various forms, as shown in the drawings, hereinafter will be described the presently preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the invention, and it is not intended to limit the invention to the specific embodiments illustrated.

(12) With reference to FIGS. 1-10, the showerhead assembly 1 includes a showerhead 5 having a traditional appearance including a housing 7 and a face 9. The face 9 includes nozzles 11 of any type as can be selected for providing a shower experience. The showerhead 5 may be constructed to connect directly to a threaded pipe typically found in a shower stall. However, as illustrated in the Figures, the preferred showerhead 5 is of the handheld type and thus the showerhead assembly includes a hollow handle 61. The handle 61 extends longitudinally to create a longitudinal axis. Preferably, the showerhead's face 9 is positioned to be at an angle, such as 45° to 90° relative to the handle's longitudinal axis. Furthermore, the handle 61 includes a central channel 65 for transporting water to the showerhead 5. The handle's proximal end includes male threads 67 for connecting to a flexible hose (not shown). Meanwhile, the showerhead 5 is affixed to the distal end of the handle 61.

(13) As best illustrated in FIG. 5, the handle's channel 65 supplies water to the showerhead 5. As further illustrated in FIG. 6, the showerhead 5 includes a primary water conduit 27 which transports water from the handle's channel 65 to a cavity 13 formed within the showerhead 5. As best illustrated in FIG. 5, water from a water source travels up the handle's channel 65 before being diverted into the primary water conduit 27. The showerhead's primary conduit 27 then supplies water to the cavity 13 which is formed between a cavity wall 15 and the showerhead's face 9. As best illustrated in FIGS. 5-8, the cavity wall 15 has a primary outlet hole 17 connected to the primary conduit 27 to allow water to travel from the primary conduit 27 into the cavity 13. Preferably, the showerhead assembly 1 includes an inlet diverter 19 which causes the water entering into the cavity 13 to be directed orthogonally throughout the cavity 13 instead of directly to the showerhead's nozzles 11. Water pressure in the cavity 13 causes water to be expelled uniformly through the showerhead's nozzles 11.

(14) The showerhead assembly 1 further includes a reservoir 75 for storing soap or shampoo. The reservoir 75 includes a housing 77 which forms a central chamber 79 in which the soap or shampoo is located. The reservoir 75 is connected to the showerhead 5 by a transition section 71. Preferably, the reservoir 75 is connectable and disconnectable to the transition section by providing the reservoir 75 with male threads 81 which threadably connect to female threads 73 formed on the exterior of the transition section 71. As illustrated in FIGS. 3 and 4, preferably the reservoir 75 can be detached from the rest of the showerhead assembly 1 for the introduction of shampoo or soap into the reservoir's chamber 79. In a preferred embodiment, the showerhead assembly 1 may include a cap 83 so that the shampoo or soap may be stored separately from the showerhead 5. Advantageously, soap or shampoo may be prepackaged and sold separately in a capped container 75 wherein the container's male threads 81 are constructed for connecting to the showerhead assembly's transition section 71.

(15) The showerhead assembly's reservoir 75 is connected to the showerhead assembly's cavity 13 by an inlet conduit 29 and an outlet conduit 31. Any water in the cavity 13 is capable of passing through an inlet hole 21 formed in the cavity wall 15 into the inlet conduit 29 so as to enter the reservoir's chamber 79. Water entering the reservoir 75 is capable of mixing with any fluid previously located within the reservoir, such as soap or shampoo. Thereafter, the mixture of water and soap or shampoo is then capable of re-entering the cavity 13 by traveling through outlet conduit 31 through an outlet hole 23 formed in the cavity wall 15.

(16) Preferably, the showerhead assembly includes a controller assembly 39 for selectively allowing water to pass through the transition section 71 into and out from the reservoir 75 so as to selectively allow shampoo or soap to enter to the showerhead assembly's cavity 13, and in turn to be sprayed from the nozzles 11. The controller may comprise various switching apparatus as can be determined by those skilled in the art. However, as illustrated in the Figures, the preferred controller assembly includes an obstructer plate 41 which can be selectively rotated to cover the cavity wall's inlet diverter 19, inlet hole 21 and outlet hole 23.

(17) As best illustrated in FIGS. 6-10, the preferred obstructer plate 41 includes a plate inlet hole 45, a plate outlet hole 47, and a tab 43. The plate 41 is rotatably attached to the cavity wall 15 by a pin 49 which passes into a circular hole 25 formed in the cavity wall. The plate 41 is capable of rotating about an axis defined by the pin 49 so as to enable one to selectively align the plate inlet hole 45 with the cavity wall inlet hole 21, and selectively align the plate outlet hole 47 with the cavity wall outlet hole 23. Once these holes are properly aligned, water from within the cavity 13 is capable of travelling through these holes. Furthermore, when the holes are aligned, water travels through the inlet conduit 29 so as to allow a mixture of water and shampoo or soap to form in the reservoir. The mixture of water and shampoo or soap then passes through outlet conduit 31 back into the cavity 13 so as to be dispensed from nozzles 11.

(18) When shampoo or soap is not intended to be sprayed from the nozzles 11, the obstructer plate 41 is rotated so that plate inlet hole 45 does not align with the cavity wall inlet hole 21, and the plate outlet hole 47 does not align with the cavity wall outlet hole 23. Similarly, the plate's tab 43 can be made to align and block the flow of water from the inlet diverter 19. Preferably, the tab 43 only predominantly, but does not totally, block the supply of water through the inlet diverter 19 so that at least a trickle of water continues to be expelled from the nozzles 11 so as to maintain constant water temperature that is being expelled from the nozzles 11.

(19) Rotation of the controller assembly's plate 41 is controlled by a switch 51 having a slidable button 53 and a lever arm 55. Preferably, the switch's arm 55 has a hole which is keyed to accept the plate's pin 49. As illustrated in FIGS. 6-8, the controller assembly 39 preferably provides three settings. As illustrated in FIG. 6, when the button 53 is positioned in a first setting, the plate's inlet hole 45 and outlet hole 47 are not aligned with the cavity wall's inlet hole 21 and outlet hole 23 so that water is prevented from flowing through the inlet conduit 29 and outlet conduit 31. However, the plate's tab 43 does not block the inlet diverter 19 so that water is capable of entering the cavity 13 from the hollow handle 61, and the water is then expelled through nozzles 11. However, any soap or shampoo within the reservoir 75 is not capable of being introduced into the flow of water expelled from the nozzles.

(20) In a second setting illustrated in FIG. 7, the switch's button 53 is depressed downwardly so as to rotate the plate 41 so as to properly align the plate's inlet hole 45 and outlet hole 47 with the cavity wall's inlet hole 21 and outlet hole 23. In this setting, the plate's tab 43 continues to not block the flow of water through the inlet diverter 19. Water is capable of entering the cavity 13 from the hollow handle, and water is further capable of passing through the inlet conduit 29 into the reservoir 75. Water mixes with the soap or shampoo within the reservoir before then travelling through the outlet conduit 31 to once again enter into the cavity 13. The mixture of water and shampoo or soap entering the cavity 13 then mixes with additional water still being introduced through the inlet diverter 19 before being sprayed through the showerhead's nozzles 11.

(21) In still a third setting illustrated in FIG. 8, the switch's button 53 is pushed upwardly so as to rotate the plate 41 so as to block the cavity wall's inlet hole 21, and outlet hole 23. Furthermore, the plate's tab 43 is rotated to obstruct the inlet diverter 19. The inlet conduit 29 and outlet conduit 31 are completely blocked so that any shampoo within the reservoir 75 is incapable of entering into the cavity 13. In addition, the inlet diverter 19 is partially blocked by the tab 43, but a trickle of water is capable of entering into the cavity 13 which is then expelled through nozzles 11.

(22) Advantageously, the showerhead assembly 1 of the present invention includes an integrated reservoir 75 for storing soap or shampoo. Furthermore, the reservoir is disengagable from the showerhead 5 so as to be easily filled or replaced with a prepackaged shampoo or soap container or the like.

(23) While a preferred showerhead assembly has been illustrated and described, it would be apparent that various modifications can be made without departing from the spirit and scope of the invention. Still alternative embodiments may be envisioned by those skilled in the art after consideration of the present disclosure. For example, a showerhead assembly of the present invention may include two or more reservoirs instead of just a single reservoir. Such a multi-reservoir showerhead assembly would include an additional inlet conduit and an additional outlet conduit which extend through the transition section to connect each additional reservoir to the showerhead's cavity. In addition, the controller assembly would be modified, such as by including additional holes in the obstructer plate, to selectively allow or obstruct fluids from flowing from the additional reservoirs through the additional conduits to the cavity. Thus, the present showerhead assembly is not intended to be limited to the single reservoir construction which is primarily described and illustrated herein.

(24) Accordingly, it will be apparent that various modifications can be made without departing from the spirit and scope of the invention. Therefore, having described my invention in such terms such as to enable a person skilled in the art to understand the invention, recreate the invention and practice it, and having presently identified the presently preferred embodiment thereof,
