The present invention relates to showerheads.
Showerheads are commercially available in numerous designs and configurations for use in showers, faucets, spas, sprinklers and other personal and industrial systems. The vast majority of showerheads include spray heads which may be categorized as being either stationary or oscillating and have either fixed or adjustable openings. Stationary spray heads with fixed jets are the simplest constructions consisting essentially of a central conduit connected to one or more spray nozzles directed to produce a constant pattern. The stationary spray showerheads cause water to flow through the construction to contact essentially the same points on a user's body in a repetitive fashion.
Multifunction showerheads are able to deliver water in many different spray patterns such as a fine spray, a coarse spray, a pulsating spray, or even a flood pattern providing high fluid flow but decreased velocity. Of course, many other spray patterns may also be provided.
A conventional multifunction showerhead generally requires the user to turn a selector ring or dial on the showerhead faceplate in order to select a desired function. Other common constructions include a faceplate with spray jets located in concentric circular patterns. An internal controller, such as controlled by buttons or the like, may be operated to direct the incoming water to any of the various patterns. Examples of such constructions are disclosed in U.S. Pat. Nos. 5,433,384 and 6,622,945.
A handheld showerhead assembly typically includes a hollow handle connected to a water supply by a flexible rubber hose. The handle has a proximal end which typically has a threaded inlet for connecting to a rubber hose. Meanwhile, at the handle's distal end, the showerhead assembly includes a showerhead including a plurality of nozzles for ejecting water. Typically, the handle and showerhead face are angled relative to one another so that water is ejected at approximately 90° relative to the handle's longitudinal axis.
Advantageously, the showerhead handle allows users to manipulate the spray nozzles into various positions and alignment to assist in the cleaning process. Unfortunately, though handheld showerheads provide many advantages compared to their fixed showerhead counterpart, handheld showerheads still suffer from several disadvantages. For example, many handheld shower assemblies do not allow a user to direct water to multiple locations at the same time.
More recently, shower stalls have been provided with a primary showerhead, and additional nozzles which project directly from the shower stall's walls which spray water in different directions than the primary showerhead. Unfortunately, these constructions require that expensive plumbing additions be made to the shower stall facility. Further, the wall nozzles cannot be moved to provide the variety that would be desirable for a shower user.
Bathers often use a variety of soaps, scrubs and shampoos when showering. Unfortunately, this can result in shower stalls being littered with a variety of dispensing bottles. Furthermore, bathers must physically manipulate each bottle to dispense a liquid, such as shampoo.
Thus, it would be advantageous to provide a showerhead assembly that eliminated at least one fluid container from a bathroom shower stall. Furthermore, it would be advantageous to provide a showerhead assembly that facilitated the application of a fluid, such as shampoo or soap, upon a bather.
To this end, numerous attempts have been made to produce a showerhead which incorporated a soap and/or shampoo bottle. These include showerheads described in U.S. Pat. Nos. 3,402,892; 4,211,368; and 7,661,607 among others. These showerhead constructions typically entail integrating or attaching a reservoir, holding soap or shampoo, to the fixed or handheld showerhead. One or more conduits allow the liquid within the reservoir to drip or flow into the water stream before being expelled from the showerhead.
Unfortunately, these constructions are prone to clogging or do not allow the liquids within the reservoir to thoroughly mix with water before being expelled from the showerhead nozzles. This can result in the uneven distribution of the liquid soap or shampoo from the nozzles Furthermore, the lack of mixing can result in clogged conduits.
Therefore, it would be desirable to provide an improved showerhead with integrated reservoir for storing a liquid that provided improved mixing of the stored liquid with water prior to the mixture being expelled from the showerhead nozzles.
Moreover, it would be desirable to provide a showerhead assembly that did not require expensive modifications to the traditional shower stall architecture such as the introduction of additional plumbing within the walls of the shower stall.
Briefly, in accordance with the invention, an improved showerhead apparatus is provided which includes a hollow handle, a housing, a disengagable reservoir which stores soap or shampoo and is connected to the showerhead housing by a transition section, and a controller assembly so as to selectively allow fluid to pass through the assembly and expel out the nozzles.
Like typical handheld showerhead apparatus, the showerhead apparatus of the present invention includes an elongate hollow handle having a central channel. The handle has a proximal end which preferably is threaded for connecting to a traditional flexible hose which in turn is connectable to a water supply, such as a pipe projecting from a shower stall. Additionally, the central channel is in fluid connection with the showerhead's primary water conduit so as to release water from a primary outlet hole for expelling water to the showerhead. Like traditional handheld showerhead assembly, the handle extends longitudinally, defining an axis by which the showerhead face and resulting spray are angled so as to be more manageable within a shower. Preferably, the showerhead is positioned to be at an angle, such as 45° to 90° relative to the handle's longitudinal axis.
Additionally, the preferred showerhead can be relatively traditional in construction including a housing and a face having nozzles. In some embodiments, the face comprises supplementary nozzles. Preferably, the showerhead includes a cavity which is formed between the face and a cavity wall. The cavity wall comprises an inlet diverter which is connected to the primary outlet hole so as to receive water from the hollow handle and allow such water to travel into the cavity. Specifically, the inlet diverter causes such water to be projected throughout the cavity in an orthogonal fashion instead of being expelled directly through the showerhead's nozzles. Furthermore, water pressure in the cavity allows for uniform water dispersal through the showerhead's nozzles.
The cavity wall further comprises an inlet hole in fluid connection with an inlet conduit, and an outlet hole in fluid connection with an outlet conduit. Additionally, the inlet conduit and outlet conduit are in fluid connection with a transition section which connects the showerhead to a reservoir. In the preferred embodiment, the reservoir includes male threads so as to be engagable and disengagable with the female threads formed on the exterior of the transition section. The detachable reservoir allows for the user to introduce shampoo or soap into a central chamber residing within the reservoir. Preferably, the detachable reservoir includes a cap so as to allow for separate storage of the reservoir from the showerhead.
In the preferred embodiment, the reservoir includes a housing which forms the central chamber for storing soap or shampoo and accepts water from the inlet conduit. Specifically, water is capable of passing from the cavity through the inlet hole and into the inlet cavity so as to enter the reservoir chamber and mix with fluid previously located therein, such as soap or shampoo. Subsequently, the mixture of fluid with water is capable of exiting the chamber through the outlet conduit so as to enter the cavity through the outlet hole.
Preferably, the showerhead assembly further comprises a controller assembly having an obstructer plate and button, which allows the inlet diverter, inlet hole, and outlet hole to be selectively covered and uncovered so that water and fluid may accordingly pass through the showerhead assembly. Specifically, the plate is rotatably attached to the cavity wall by a pin which passes through a circular hole formed in the cavity wall. More specifically, the obstructer plate includes a plate inlet hole and plate outlet hole. The pin allows the plate to rotate upon an axis so as to enable one to selectively align the plate inlet hole with the cavity wall inlet hole, thereby enabling the passage of water to the reservoir chamber. Further, in this rotation, the plate outlet hole is selectively aligned with the cavity wall outlet hole, thereby enabling the flow of fluid mixture to the cavity.
In some embodiments, the obstructer plate further includes a tab. Specifically, in these embodiments, the tab can be made to selectively align and block the flow of water from the inlet diverter. In some preferred embodiments, the tab only partially blocks the inlet diverter so as to enable the supply of water from the handle to at least trickle into the cavity and expel from the nozzles, thereby maintaining a constant water pressure. In other embodiments, the showerhead assembly further comprises a flow setting assembly which includes a diverter plate. Specifically, the diverter plate can include a tab configured to variably align and/or block the flow of water from the inlet diverter. In this manner, the diverter plate's tab allows the water pressure and/or flow to vary. In these embodiments, water can flow through showerhead assembly and expel from the one or more nozzles independent of the positioning of the obstructer plate.
In some embodiments, rotation of the controller assembly is accomplished by way of a button and a lever arm. In some embodiments, the button is a slidable button. In some embodiments, the button is a push button. Those of skill in the art will recognize that other controller assembly features and buttons can be utilized without departing from the scope of this disclosure. Additionally, and preferably, the lever arm has a hole keyed to accept the obstructer plate's pin.
Furthermore, in some preferred embodiments, the controller assembly provides three settings. Upon the user manually sliding the button to the first setting position, the obstructer plate is selectively rotated so that the plate's inlet hole and outlet hole are not aligned with the cavity wall's inlet hole and outlet hole. Consequently, this unaligned configuration prevents water and fluid flow through the inlet conduit and outlet conduit, respectively. In the first setting position, the tab does not block the inlet diverter and water is capable of entering the cavity and thereby spraying through the showerhead nozzles.
In some preferred embodiments, upon the user manually sliding the button to the second setting position, the obstructer plate is selectively rotated so as to properly align the plate's inlet hole and outlet hole with the cavity wall's inlet hole and outlet hole. In this second setting, the tab does not block the water flowing through the inlet diverter. As a result, water entering the cavity from the handle is capable of traveling through the inlet conduit and entering the reservoir chamber. This water mixes with the fluid located within the reservoir chamber so as to produce a mixture which then flows from the chamber through the outlet conduit. Consequently, the outlet conduit transports this mixture into the cavity, wherein the mixture is additionally mixed with water entering the cavity through the inlet diverter. Thereafter, the new mixture is expelled through the nozzles.
In some preferred embodiments, and in accordance with the user sliding the button to the third setting position, the plate is selectively rotated so as to block the cavity wall's inlet hole and outlet hole. The inlet conduit and outlet conduit remain blocked in this rotated position so as to prevent any fluid within the reservoir from entering the cavity. Alternatively, the tab is positioned so as to only partially obstruct the inlet diverter, thereby allowing only a trickle of water to enter the cavity through the handle. Therefore, water trickling into the cavity is expelled through the nozzles.
In other preferred embodiments, the controller assembly provides two settings. In the first setting, or when the button has not been pressed by a user, the obstructer plate is selectively rotated so that the plate's inlet hole and outlet hole are not aligned with the cavity wall's inlet hole and outlet hole. In this first setting, though water is capable of entering the cavity from the hollow handle and then expelling through the nozzles, any soap or shampoo within the reservoir is not capable of being introduced into the flow of water expelled from the nozzles.
Further, in some embodiments, in the second setting, or when the user has depressed downwardly onto the button, the obstructer plate is selectively rotated so as to properly align the plate's inlet hole and outlet hole with the cavity wall's inlet hole and outlet hole. In this second setting, water entering the cavity from the handle is capable of traveling through the inlet conduit and entering the reservoir chamber. As such, water mixes with the soap or shampoo within the reservoir before then travelling through the outlet conduit to once again enter into the cavity for expellation therefrom.
Thus, it is an object of the present invention to provide a showerhead assembly having an improved construct so as to facilitate the application of a fluid, such as shampoo or soap, onto the user.
Furthermore, it is an additional object of the present invention to provide a showerhead assembly that provides a controller for allowing the user to selectively dispense fluid into the stream of water being ejected from the showerhead nozzles.
Other features and advantages of the present invention will be appreciated by those skilled in the art upon reading the detailed description which follows with reference to the drawings.
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.
With reference to
In some embodiments, and with reference to the showerhead assembly depicted in, e.g.,
With reference to
As best illustrated in
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 71 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
The showerhead assembly's reservoir 75 is connected to the showerhead assembly's cavity 13 (see, e.g.,
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 and/or 111. The controller assembly 39 may comprise various switching apparatus or button mechanisms as can be determined by those skilled in the art. However, as illustrated in the Figures, the preferred controller assembly 39 includes an obstructer plate 41 which can be selectively rotated to cover the cavity wall's inlet hole 21 and outlet hole 23.
As best illustrated in
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.
Rotation of the controller assembly's plate 41 is controlled by a switch 51 having a button 53 and a lever arm 55. In some preferred embodiments, the button 53 is a slidable button 53. Preferably, the lever arm 55 has a hole 57 which is keyed to accept the plate's pin 49. As illustrated in

In some embodiments, and as illustrated in
Rotation of the diverter plate 201 (and sliding of the tab 43 along the ledge 203) is controlled by a switch 210 having a switch button 211 and a control arm 212. Preferably, though not illustrated, the control arm 212 has an opening 213 which is keyed to accept the notch 202. In this manner, the control arm 212 is operatively coupled with the diverter plate 201 and can control its movement. In preferred embodiments, the control arm 212 can be moved up and down so as to change and control water flow/pressure settings. Specifically, the switch button 211 can move between a plurality of positions. More specifically, the switch button 211 can move anywhere between a first position and a second position. Further, the control arm 212 moves up and/or down as a function of the movement of the switch button 211.
In some exemplar embodiments, when the switch button 211 is in the first position (shown in
Moreover, in some exemplar embodiments, when the switch button 211 is in a position between the first position and the second position (shown in
Those of skill in the art will appreciate that the user can move the switch button 211 to various different positions between the first position and the second position so as to select a desired water pressure between the maximum water pressure and minimum water pressure.
Further, those of skill in the art will recognize that other means aside from a diverter plate 201 and tab 43 can be utilized to align and or block the inlet diverter 19 so as to vary the water pressure and/or flow without departing from the scope of the disclosure.
Advantageously, the showerhead assembly 1 of the present invention includes an integrated reservoir 75 for storing soap or shampoo. Furthermore, the reservoir 75 is disengagable from the showerhead 5 so as to be easily filled or replaced with a prepackaged shampoo or soap container or the like.
While preferred showerhead assemblies have 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.
It will be understood by those of skill in the art that any of the showerhead assemblies described herein, are meant to be illustrative only, and that the individual elements, or any combination of elements, depicted and/or described for a particular embodiment or figure are freely combinable with any other element, or any combination of other elements, depicted and/or described with respect to any of the other embodiments.
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, I claim:
The present application is a continuation of U.S. patent application Ser. No. 17/150,266, filed Jan. 15, 2021, which claims priority to U.S. Provisional Patent Application No. 63/026,623, filed May 18, 2020, the disclosures of which are hereby incorporated by reference in their entireties for all purposes.
