The present application relates generally to the field of showers, baths, and faucets. The present application relates more specifically to the field of showers.
Conventional shower systems receive a pressurized supply of water and provide substantially continuous streams of water from a showerhead by forcing the water through nozzle holes to create streams. Some streams may break into drops via aerodynamics after the stream has left the showerhead. These systems may use a relatively high volume of water to produce the streams of water. Thus, there is need for a shower that produces a satisfying shower experience at a lower flow rate.
Some shower systems provide streams of water from ceiling panels, but do not simulate the sound and feel of rain. Some users may prefer the feel of rain to that of a shower. That is, some users may prefer the experience of showering in the rain. Thus, there is a need for a shower that produces a more realistic feel of rain.
One embodiment relates to a shower assembly having a panel including a wall and a first plurality of holes passing through the wall from the inner surface to the outer surface, each hole of the first plurality of holes comprising an inlet and an outlet. The wall at least partially defines a reservoir and has an outer surface on a side of the wall toward a showering area and an inner surface on a side of the wall away from the showering area. When water is provided to the reservoir, water passes through the first plurality of holes, forms a drop at the outlet of each of the first plurality of holes, and falls from the panel as a plurality of drops.
Another embodiment relates to a shower assembly having a panel and a stopper movable between a first position and a second position. The panel includes a first region having a plurality of first openings passing through the panel and a second region having a plurality of second openings passing through the panel. When the stopper is in the first position, water provided to the shower assembly is permitted to pass through the plurality of first openings but is prevented from passing through the plurality of second openings. When the stopper is in the second position, water provided to the shower assembly is permitted to pass through the plurality of second openings.
Another embodiment relates to a shower assembly including a top wall; a bottom wall; at least one sidewall extending between the top wall and the bottom wall; a chamber defined by the top wall, the bottom wall and the at least one sidewall; an inlet port configure to receive water from a water source and to provide water into the chamber; and a first plurality of holes passing through the bottom wall, each hole of the first plurality of holes comprising an inlet and an outlet. The shower assembly is configured such that, when water is provided to the chamber at a first operating flow rate, water partially fills the chamber to a first height, passes through the first plurality of holes by gravitational force, forms a drop at the outlet of each of the first plurality of holes, and falls from the bottom wall as a plurality of drops.
Another embodiment relates to a shower assembly having an inlet, a reservoir, a plurality of first outlets, and a plurality of second outlets. The inlet is for receiving water from a water source, and is configured to restrict water flow from the water source to a maximum inlet flow rate. The reservoir receives from the inlet. The plurality of first outlets are configured to pass water from the reservoir. The plurality of second outlets are configured to selectively pass water from the reservoir. The shower assembly is configured for a user to selectively control whether water passes through the plurality of second outlets. A sum of a first collective flow rate of the plurality of first outlets and a second collective flow rate of the plurality of second outlets is greater than the maximum inlet flow rate.
Another embodiment relates to a shower assembly comprising an inlet port, a reservoir, a plurality of first outlets, and a plurality of second outlets. The inlet port is for receiving water from a water source at a source flow rate. The reservoir receives water from the water source through the inlet port. The plurality of first outlets are configured to continuously pass water from the reservoir, and have a first collective flow rate that is approximately equal to the source flow rate. The plurality of second outlets configured to selectively pass water from the reservoir simultaneous with water being passed from the plurality of first outlets.
Another embodiment relates to a shower assembly having a reservoir comprising a first plurality of outlet holes and a second plurality of outlet holes. The reservoir is configured to receive water from a water source at a source flow rate. The reservoir is configured such that during a first operational state, water exits the reservoir only through the first plurality of outlet holes at a first flow rate that does not exceed the source flow rate. The reservoir is configured such that during a second operational state, water exits the reservoir through the first plurality of outlet holes at the first flow rate and the second plurality of outlet holes at a second flow rate, and a total of the first flow rate and the second flow rate of water exiting the reservoir through the first and second pluralities of outlet holes exceeds the source flow rate.
Another embodiment relates to a control system for a shower assembly, comprising processing electronics configured to control, in relation to a shower assembly of any of the above embodiments, at least one of a flow rate of the water, a temperature of the water, a position of the stopper, an audio device, a lighting system, a scent emitter, a disinfecting system, and a trajectory of the drops.

Rain, however, is different than the streams 12 provided by a conventional showerhead 10. Rain looks different, rain sounds different, and rain feels different. This is because rain is made of discrete drops 20 of water instead of continuous streams 12 of water. Referring to

The panel 102 includes a wall (e.g., first wall, lower wall, spray wall, drip wall, etc.), shown as bottom wall 110, having a first surface (e.g., inner surface, inlet side, etc.), shown as top surface 112, and a second surface (e.g., outer surface, outlet side, spray face, drip face, etc.), shown as bottom surface 114 opposite the top surface 112. According to the exemplary embodiment, the bottom surface 114 is on a side of the bottom wall 110 that is toward a showering area, and the top surface 112 is on a side of the bottom wall 110 that is away from a showering area. The panel 102 may further include one or more sidewalls 116 extending up from the bottom wall 110 and a top wall 118. A reservoir 120 (e.g., chamber, cavity, tank, etc.) is at least partially defined by one or more of the bottom wall 110, sidewalls 116, and top wall 118. The bottom wall 110 may be formed of any suitable material having appropriate machine-ability or mold-ability (e.g., acrylic, silicone, polycarbonate, Lithocast®, stainless steel, etc.). Referring briefly to
The panel 102 may be opaque, translucent, or transparent. A translucent panel may allow light through the panel without showing mineral buildup in the reservoir. A transparent panel may allow light and any mineral buildup to be seen through the panel 102, and a hydrophobic pattern may be applied to the top surface 112 of the panel 102 to cause the mineral buildup to form in an aesthetically pleasing pattern. The transparent or translucent panels may be backlit (e.g., by one or more lights 212 shown in
The panel 102 may open to permit access to the reservoir 120 for cleaning and maintenance. According to various embodiments, the bottom wall 110 may releasably couple to the sidewalls 116, or the sidewalls 116 may be releasably coupled to the top wall 118. For example, the various walls (bottom wall 110, sidewalls 116, top wall 118, etc.) may be snapped together, latched together, or coupled by one or more hinges. According to the exemplary embodiment shown, the bottom wall 110 and the sidewalls 116 form a unitary structure that is rotatably coupled to the top wall 118 via a hinge 122.
The source of water may be pressurized (e.g., from a municipal water supply, well pump, water tower, elevated water tank etc.), and the flow of water to the panel 102 may be controlled by a control system 200, which may include one or more fluid control valves 202 (e.g., volume control valve, mixing valve, thermostatic valve, pressure balance valve, etc.). The fluid control valve 202 may also be configured to limit or restrict a flow rate of water received from a water source (e.g., a water source flow rate) to reduce a flow rate into the shower assembly 100, itself, (e.g., a maximum inlet flow rate). For example, instead or in addition to the fluid control valve 202, the inlet 106 may include a flow restrictor that restricts water flow from the water source, or may otherwise be configured to restrict flow, such that maximum inlet flow to the shower assembly 100 is limited, for example, according to local regulations. As will be described in more detail below, it is contemplated that during an exemplary use of the shower assembly 100, the reservoir 120 may be only partially filled (e.g., not be completely filled) and, therefore, not pressurized. Thus, the top wall 118 may be provided to prevent overflow, contain inadvertent splashing, facilitate cleaning, etc.
According to one embodiment, the shower assembly 100 may include a disinfecting system 700 that disinfects portions of the shower assembly 100 to kill bacteria. For example, another embodiment of the disinfecting system 700 may include a heater that raises the temperature of the fluid control valve 202 to kill any bacteria therein. Exemplary disinfecting systems are described in U.S. patent application Ser. No. 13/797,263, entitled “Mixing Valve,” and U.S. patent application Ser. No. 13/796,337, entitled “Plumbing Fixture with Heating Elements,” both of which were filed Mar. 12, 2013, and are incorporated herein by reference in their entireties. Operation of the disinfecting system may be controlled by the control system 200 described in more detail below.
Before discussing further details of the panel 102 and/or the components thereof, it should be noted that elements of various sizes and geometry in the exemplary embodiment are shown with an alphanumeric reference numeral. For the purpose of clarity, elements are generically referred to using only the numeric reference numeral.

The bottom wall 110 includes a first region 124 (e.g., outer region, dripping region, etc.) and a second region 126 (e.g., inner region, streaming region, etc.). The first region 124 and the second region 126 may be of any suitable sizes or shapes. For example, the first regions 124 and/or the second region 126 may circular, oval, elliptical, regular or irregular polygons, Reuleaux polygon, or any other suitable shape, which may have linear or curved sides. According to the exemplary embodiment shown, the first region 124 has an outer periphery of 24 inches by 24 inches (approximately 60 cm by 60 cm) square, and the second region 126 is substantially circular with a diameter of approximately 9 inches (approximately 23 cm). According to other exemplary embodiments, the first region 124 has an outer periphery of approximately 19 inches by 19 inches (approximately 48 cm by 48 cm) square, The dimensions could, of course, differ in other embodiments. For example, the first region 124 could be square or rectangular having at least one dimension of 21 inches (approximately 53 cm), 32 inches (approximately 81 cm), 36 inches (approximately 91 cm), etc. According to other embodiments, the shower assembly 100 may be modular, for example, formed of a plurality of adjoining (e.g., contiguous, adjacent, etc.) panels. The adjoining panels may, for example, each form a quadrant of the first region 124 and the second region 126. A modular assembly may facilitate an increased area of drop formation (i.e., raining) to accommodate additional users and may facilitate an increased flow rate (e.g., drops per second, volume per second, etc.), which may provide therapy benefits to the user, for example, increasing heat transfer to the user, increasing the temperature of the showering area, and increasing the humidity of the showering area. According yet other embodiments, the shower may include a plurality of spaced apart panels; for example, each panel being spaced approximately 4 inches (10 cm) from neighboring panel, and each panel may have different patterns and distributions of holes 108 to provide zones of different rain-type characteristics.

A bore 132 extends between the inlet 130 and the outlet 136, providing a passageway for water to flow between the inlet 130 and the outlet 136. The bore 132 is configured to restrict the flow of water from the reservoir 120 to the outlet 136 such that the surface tension of water causes a drop 20 to form on the outlet 136. The diameter of the bore 132 is a function of the pressure of the water in the bore 132 and the inlet 130. In the exemplary embodiment shown, water flows through the bore 132 under the force of gravity, so the maximum pressure is limited to the height or depth of the panel 102. That is, the maximum pressure of water flowing in the reservoir is not impacted or pressurized by a supply pressure (e.g., line pressure) of the water source. Furthermore, to achieve a desired water height, and thereby pressure, within the reservoir, the number of holes 108 may be adjusted relative to the expected flow rate, for example if restricted by the inlet, into the shower assembly 102. According to other embodiments, the panel 102 may be pressurized by the supply of water to the panel, in which case the diameter of the bore 132 may be narrow to further restrict the flow of water from the reservoir 120 to the outlet 136. When the drop 20 reaches a predetermined size (e.g., critical stage), gravity overcomes the surface tension of the water and causes the drop 20 to decouple and fall from the panel 102. The size and rate of the drop 20 at the critical stage is a function of the material properties bottom wall 110, the temperature of the water (which in turn affects the temperature of the bottom wall), impurities in the water, the diameter of the bore 132, the length of the bore 132, and the geometry of the outlet 136. Applicants have determined how to regulate the flow of water to prevent streaming across operating conditions. Applicants have determined ranges of the bore 132 diameters and the outlet 136 geometries that provide consistent drop 20 formation across a variety of materials, operating temperatures, and bore lengths. More particularly, the geometries of the outlets 136 affect the size of the drops 20, and the diameter of the bore 132 affects drop formation versus streaming. That is, the geometry of each of the holes 108 is configured to produce discrete drops of water and to prevent streaming when water in the reservoir 120 is at or below the maximum pressure in the reservoir 120.
The diameter of the bore 132 is preferably less than 0.04 inches. According to another embodiment the diameter of the bore 132 is between 0.01 inches and 0.04 inches. According to the exemplary embodiment shown, the diameter of bore 132 is preferably between 0.025 inches and 0.03 inches. While the bores 132 are shown to be of the same diameter, it is contemplated that in various embodiments, the diameters of the bores 132a, 132b, 132c may be the same or different. For example, the diameter of the bore 132c may be slightly larger than the diameter of the bore 132b, which may be slightly larger than the diameter of the bore 132a. The slightly larger bore diameter for the large outlets 136 may increase flow rate through the bore 132, which in turn may increase the rate (i.e., drops per second) of drop formation, thereby bringing the rate of large drop formation closer to that of the rate of medium or small drop formation.
As shown, the outlet 136 is hemispherical. However, it is contemplated that the outlet geometry make take other shapes, for example, ovoid, pyramidical, conical (shown, e.g., in

As shown, the outlet 136c″ is substantially conical and defined by a nozzle 134c″. The hole 108c″ includes a rounded shoulder 133 that smoothly blends the surface of the bore 132c″ with the surface of the outlet 136c″. Providing a smooth transition facilitates drop formation and avoids discontinuities which may cause water to separate from the surface of the bore 132c″, shoulder 133, or outlet 136c″. The bore 132c″ is also shown to have walls that extend radially outward as the walls extend axially away from the inlet 130c″. Accordingly, the orifice formed by the bore 132c″ is a point restriction. The point restriction facilitates more rapid formation of drops. Further, advantageously, the shortened bore 132c″ may flex in response to the flexing of the nozzle 134c″ (e.g., with a finger); therefore, mineral buildup in the orifice may be cleaned (e.g., removed, broken up and flushed out by water, etc.) by rubbing a finger over the nozzle 134c″. According to various embodiments, the bore 132c″ may be conical or frustoconical. According to the embodiment shown, the sidewall of the bore 132c″ has a continuous curve that blends smoothly into the surface of the outlet 136c″. According to one embodiment, the bore 132c″ and the outlet 136c″ has an inverted (i.e., upside-down) funnel shape.
According to some embodiments, the diameter of bore 132″ is preferably between 0.025 inches (approximately 0.63 mm) and 0.03 inches (approximately 0.76 mm) at its narrowest point. According to the exemplary embodiment shown, the diameters of bores 132″ are between 0.027 inches (approximately 0.69 mm) and 0.029 inches (approximately 0.74 mm) at its narrowest point. The diameters of the bores 132a″, 132b″, 132c″ may be the same or different. For example, the diameter of the bore 132c″ is shown to be slightly larger than the diameter of the bore 132b″, which is shown to be slightly larger than the diameter of the bore 132a″. According to the exemplary embodiment shown, the diameters of the outlets 136″ range from about 0.14 inches (approximately 3.55 mm) to about 0.335 inches (approximately 8.5 mm) at their widest points. According the exemplary embodiment shown, the diameter of the outlet 136b is about 0.17 inches.

The shower assembly 100 may be configured such that, when water is provided to the reservoir at a first operating flow rate (e.g., a low flow rate), water partially fills the reservoir above 120 the first height 141, passes through a plurality of first holes 108e by gravitational force, forms a drop 20 at the outlet 136e of each of the plurality of first holes 108e, and falls from the bottom wall 110 as a plurality of drops 20. At the first operating flow rate, the rate of water exiting through the first holes 108e may be equal to the rate of water entering the reservoir 120 such that the height of the water in the reservoir 120 does not exceed the height inlets 130f.
The shower assembly 100 may be configured such that when water is provided to the reservoir at a second operating flow rate (e.g., a moderate flow rate), water partially fills the reservoir 120 above the third height 143, passes through the plurality of first holes 108e and a plurality of second holes 108f by gravitational force, forms a drop 20 at the outlet of each of the plurality of first holes 108e and the plurality of second holes 108f, and falls from the bottom wall 110 as a plurality of drops 20. At the second operating flow rate, the rate of water exiting through the first and second holes 108e, 108f may be equal to the rate of water entering the reservoir 120 such that the height of the water in the reservoir 120 does not exceed the height inlets 130g.
The shower assembly 100 may be configured such that when water is provided to the reservoir at a third operating flow rate (e.g., a high flow rate), water partially fills the reservoir above the fifth height 145, passes through the plurality of first holes 108e, the plurality of second holes 108f, and a plurality of third holes 108g by gravitational force, forms a drop 20 at the outlet of each of the plurality of first holes 108e, the plurality of second holes 108f, and the plurality of third holes 108g, and falls from the bottom wall 110 as a plurality of drops 20. At the third operating flow rate, the rate of water exiting through first, second, and third holes 108e, 108f, 108g may be equal to the rate of water entering the reservoir 120 such that the water does not fill the reservoir 120. According to an exemplary embodiment, the rate of water exiting through first, second, and third holes 108e, 108f, 108g is approximately 2.5 gallons per minute. Because of the feeling of individual drops 20, a user may enjoy a satisfying shower experience at a lower flow rate than required by streams 12 of water. That is, the individual drops 20 of water may cause a user to perceive a greater flow rate than is perceived from an equivalent flow rate of streams 12 of water. Accordingly, a user may use less water while perceiving a conventional, higher flow rate. Thus, at the third operating flow rate, the rate of water exiting through first, second, and third holes 108e, 108f, 108g may be configured to be equal to the rate of water entering the reservoir 120 and the capacity of the fluid control valve 202, which may be less than 2.5 gallons per minute.
According to various embodiments, the outlets 136e, 136f, 136g may have the same or different geometries. For example, the outlet 136f may be larger than 136e such that larger drops 20 are formed on the outlet 136f. Thus, the second operating flow rate would create larger rain drops corresponding to the medium drops 20b formed in moderate rain. The holes 108g may have larger outlet 136g again to create even larger drops 20c in response to the third operating flow rate, thereby simulating a downpour. According to another embodiment, the third holes 108g may be streaming holes as described with respect to holes 108d and 108d′ in

According to the exemplary embodiment shown, the holes 108a, 108b, 108c are substantially similar to the holes 108a, 108b, 108c shown and described in
According the exemplary embodiment shown, the stopper 152 includes a first portion 153 and a seal 156 coupled to the first portion 153. As shown, the first portion 153 includes a lower wall 154 (e.g., bottom wall, dam, etc.), and the seal 156 is coupled to the lower wall 154. The seal 156 may be an O-ring seated in an annular groove extending about an outer periphery of the lower wall 154. When the stopper 152 is in the first position, the seal 156 separates the first region 124 from the second region 126. When the stopper 152 is in the first position, the lower wall 154 is located adjacent the second region 126 of the bottom wall 110 and may cover the holes 108d. When the stopper 152 is in the second position, the lower wall 154 is spaced apart from the second region 126, and the holes 108d may be uncovered. In this manner, the stopper 152 acts as a valve to prevent or permit water from flowing to the holes 108d.
The stopper 152 is further shown to include a guidewall 158 extending upward from the lower wall 154 and defining an inner opening 160. An outer sidewall 162 extends upward from the lower wall 154 about an outer periphery of the stopper 152. The outer sidewall 162 defines one or more holes 164 (e.g., slots, passages, etc.) extending through the sidewall 162, thereby facilitating water above the stopper 152 to pour off the stopper 152 when the stopper 152 is moved from the first position to the second position. Similarly, the holes facilitate water from the reservoir 120 above the first region 124 to flow onto the stopper 152, thereby pushing the stopper 152 toward the first position and increasing the sealing force on the stopper 152 and seal 156.
The exemplary embodiment of the streaming apparatus 150 is further shown to include a column 166 extending upward from the bottom wall 110 and through the inner opening 160 of the stopper 152. According to an exemplary embodiment, the guidewall 158 extends upward from the bottom wall 110 and about a perimeter of the column 166. When the stopper 152 moves between the first position and the second position, the guidewall 158 translates along the column 166, thereby guiding the motion of the stopper 152 in preventing inadvertent dislodging of the stopper 152 from above the second region 126.
The stopper 152 may move between the first position and the second position in response to an actuator (e.g., handle, lever, knob, button, cord, the motor, etc.). According the exemplary embodiment shown, a pull cord 170 extends through a passage 128 extending through the bottom wall 110 and column 166. The pull cord 170 extends over arms 168 and couples to the stopper 152, for example, for example to the sidewall 162. The pull cord 170 is routed over the arms 168 such that when a proximal end of the pull cord 170 is pulled downward, the distal end of the pull cord 170 pulls upward on the stopper 152, thereby raising the stopper 152 from the first position toward the second position. According to various embodiments, the pull cord 170 may run over a smoothed edge of the arms 168, or the pull cord 170 may run over one or more pulleys.
According to various other embodiments, the stopper 152 may be actuated via a mechanical linkage located on the panel 102, on the ceiling 104, or on another shower wall 105. For example, referring to the schematic diagram of

The panel 302 defines a reservoir 320 that may be separated by a wall 358 into a first tank 321 (e.g., dripping tank, rain tank, etc.), located above a first region 324 of the panel 302, and a second tank 322 (e.g., streaming tank, deluge tank, etc.), located above a second region of 326 of the panel 302, the wall 358 preventing or limiting water flow between the first tank 321 and the second tank 322. The holes 308a 308b, 308c of the first region 324 are configured to form drops 20, whereas the holes 308d of the second region 326 are configured to form continuous streams 12 (not shown). As described above with respect to streaming apparatus 150, when the stopper 352 is in a first position (as shown), water is prevented from streaming through holes 308d, and when the stopper 352 is in a second position (e.g., not the first position, spaced apart from the bottom wall 310, un-sealed, etc.), water is permitted to stream through the holes 308d. That is, the holes 308d are in selective fluidic communication with the second tank, whereas the holes 308a, 308b, 308c are in constant fluidic communication with the first tank.
The wall 358 may have a plurality of holes 364 therethrough to permit water to pass between the first tank 321 and the second tank 322. During operation, water enters the second tank 322 from a water source 306 and begins to fill the second tank 322. When water reaches the level of the holes 364, water passes through the wall 358 and begins to fill the first tank 321, thereby supplying water to holes 308a, 308b, 308, which in turn causes formation of drops 20. As shown, a first course (e.g., row, layer, level, etc.) of holes 364a (e.g., one or more first holes) is formed at a first height above the top surface 312 of the bottom wall 310, and a second course of holes 364b (e.g., one or more second holes) is formed as at a second height above the top surface 312. The first course of holes 364a may be sized such that the flow rate of water that may pass through the first course of holes 364a (e.g., a collective flow rate of the first holes, or a first collective flow rate) is less than the flow rate of water entering the second tank 322 (e.g., a maximum flow rate from an inlet into the second tank). Accordingly, the water level in the second tank 322 would continue to rise even as water flows from the second tank 322 to the first tank 321. The second course of holes 364b may be sized such that the flow rate of water that may pass through the first (e.g., the first collective flow rate) and second (e.g., a collective flow rate of the second holes, or a second collective flow rate) courses of holes 364a, 364b is equal to or greater than the flow rate of water entering the second tank 322 from the water source. Accordingly, the water level in the second tank 322 may rise until the water level reaches the second courses of holes 364b, and then the water flows primarily to the first tank 321.
Separating the reservoir 320 into the first tank 321 and the second tank 322, and filling the first tank 321 out of the second tank 322, have several benefits. First, they permit rapid refilling of (e.g., reduces the time required to refill) the second tank 322 in order to quickly recharge the deluge feature (e.g., douse, drench, flood, etc.). According to an exemplary embodiment, the deluge feature may release approximately two-thirds of a gallon of water over a 5 second period, and recharge the deluge feature in approximately one minute with an inlet flow rate of 1.9 gallons/minute. Second, the first tank 321 may act as a manifold to improve temperature mixing of the water to provide a more consistent experience for the user. Third, the wall inhibits flow of water from the first tank 321 to second tank 322, thereby lessening starvation of holes 308a, 308b, 308c during operation of the streaming apparatus 350. Fourth, as shown, the first course of holes 364a is above the height of a seal 356 on the stopper 352; accordingly, quickly filling the second tank 322 above the height of the seal 356 enables a head pressure to be quickly formed on the seal 356 to help stop flow through the streaming holes 308d.
According to various embodiments, the reservoirs (e.g., reservoir 120, reservoir 320, reservoir 420, reservoir 520, etc.) and/or second tanks (e.g., deluge tank 622, etc.) of this disclosure may act as an accumulator. For example, in low flow environments, the reservoirs and/or second tanks may be fluidly coupled to a showerhead so when the deluge feature is actuated, water exits the panel through the showerhead. The showerhead may be wall mounted or hand held, may be a high flow showerhead, which would drain the reservoirs relatively quickly, or may be a low flow showerhead, which would drain the reservoir relatively slowly. The concentrated flow of the showerhead may facilitate rinsing of soap, shampoo, and/or dirt from a user. Thus, the reservoirs and/or second tanks may facilitate accumulation and temporal shifting of water use in low-pressure, low flow environments to improve the bathing experience without increasing overall water usage.
According to the embodiment shown, the seal 356 is a flexible seal that extends radially outward from the stopper 352. When the stopper 352 is in the first position, the seal sealingly engages a bead 357 raised on the top surface 312 and extending around the second region 326 of the panel 302. The flexible, outwardly extending seal 356 may deflect to compensate for differences in height between the height of bead 357 and the height of the stopper 352 when the stopper 352 is in the first position.
According to the exemplary embodiment shown, the stopper 352 may be interconnected with an electric actuator 178 by a shaft 377. The electric actuator 178, which may be part of, or controlled by, control system 200 may be controlled to raise and lower the stopper 352. According to other embodiments, the stopper 352 may be actuated by any of the actuation assemblies described with respect to

A space 481 is located between the stopper 452 and the bottom wall 410 when the stopper 452 is in the first position. As shown, the space 481 is at least partially defined by a portion of the wall 458 below the ledge 459. A snorkel 465 extends from the wall 458 and defines an overflow passage into the space 481. According to the embodiment shown, the snorkel extends from a first or upper end above the first course of holes 464a. If the water level in the first reservoir 421 exceeds the height of the upper end of the snorkel 465, then the water flows through the snorkel 465, through the hole 464 in the wall 458, through the space 481, through the holes 408d in the second region 426 of the bottom wall 410, and out of the panel 402. In this manner, the snorkel 465 provides nonselective fluidic communication between the first tank or reservoir 421 and the holes 408d to allow excess water to freely pass from the first tank 421 to the holes 408d and out of the shower assembly 400. Accordingly, the snorkel 465 may prevent the reservoir 420 from being overfilled (e.g., overflowing, pressurizing, etc.), and may provide a user with an indication that the reservoir is full by releasing water from through the streaming openings 408d. The user may do nothing and enjoy the heavy downpour portion of their rain-showering experience, reduce flow to the reservoir, or may actuate the deluge feature to at least partially drain the reservoir 420.
The housing 472 and the diaphragm 474 of the actuator 470 at least partially define a chamber 476, which is fluidly coupled to the water source 406. A return mechanism, shown as a spring 478, normally biases the diaphragm 474, and therefore the shaft 477 and the stopper 452, to a second or open position. The actuator 470 is shown to be in series downstream of inlet 407; however, other arrangements are contemplated. For example, the actuator 470 and the inlet 407 could be plumbed in parallel. By moving between the open and closed positions, the stopper 452 acts as a valve to permit or prevent, respectively, water from flowing to the outlets 408d.
During operation, water from the water source 406 may pass through a filter 401 and into the second tank 422 via an inlet 407. Water from the water source 406 also enters the chamber 476, thereby pressurizing the chamber 476 and pressing on diaphragm 474. In turn, the spring 478 is compressed and the shaft 477 moves or pushes the stopper 452 into a first or closed position, which prevents water from exiting the shower assembly 400 through the plurality of streaming openings 408d. Thus, when water is permitted to flow to the shower assembly 400 from the inlet or water source 406, the actuator normally maintains the stopper 452 in a closed position. When the flow of water from the water source 406 is reduced (e.g., inhibited, slowed, stopped, etc.) to the actuator 470, the pressure in the chamber 476 reduces, the spring 478, and therefore the diaphragm 474, shaft 477, and stopper 452, is allowed to return to the second or open position, thus allowing water to stream through holes 408d. Thus, the actuator 470 moves the valve to the open position by changing the amount (e.g., reducing) of water supplied to the actuator, for example, when selectively actuated by a user. As the diaphragm returns to the second position, the water in the chamber 476 is pushed out of the chamber and may, for example, flow into the second tank 422 via the inlet 407. A normally open arrangement of the return mechanism advantageously moves the stopper 452 to an open position when the shower is turned off, which allows the panel 402 to quickly drain water, which speeds drying of the panel, which aids cleanliness and hygiene. That is, when water is not permitted to flow to the shower assembly 400, the actuator normally maintains the stopper 452 in the open position. Further draining of the panel 402 after use prevents drips and prevents water being stored in the panel long term from being uncomfortably delivered to the next shower occupant at a cold temperature.
The actuator 470 may further be configured to move the stopper 452 to the open position for a predetermined amount of time, for example, an amount of time that does not allow the second tank 422 to completely empty of water. For example, the actuator 470 may be configured such that, after the actuator 470 is actuated to move the stopper 452 to the open position, the actuator 470 moves the stopper 452 back to the closed position after only a portion of the water in the tank 422 is released (e.g., between 25% and 75% of the capacity of the second tank 422 is released with each actuation). In this manner, a user may selectively release water from the second tank 422 multiple times in succession without emptying the tank. That is, the use may actuate the valve at least twice successively (i.e., within approximately 1-2 seconds after the stopped is returned to the closed position) in order to completely empty the tank. Alternatively or additionally, the actuator 470 may be configured for a user to maintain the stopper 452 in the open position for an extended period of time (i.e., longer than a single actuation), so as to release more or all water from the second tank 422. According to other exemplary embodiments, the actuator 422 may be configured to move the stopper 452 to the open position for a sufficient amount of time for a volume of water in the second tank 422 to substantially or entirely empty through the holes 408d. For example, the actuator 470 may be configured to move the stopper 452, after being moved to the open position, back to the closed position at a time substantially coincident with the tank 422 completely emptying through the holes 408d, such that the tank 422 is substantially emptied of water.
Furthermore, the shower assembly 400 may be configured such that while the actuator 470 is actuated to release water from the second tank 422, water is continuously released from the shower assembly (e.g., through the first plurality of holes 408a, 408b, 408c and/or the second plurality of holes 408d) without interruption, so long as water is continuously supplied by the water source 406 to the shower assembly 400 itself. That is, the maximum volume of the first tank 421 and collective flow rate of the first plurality of holes 408a, 408b, 408c are configured relative to the flow rate of the water source 406 and initial volume of the second tank 422 (i.e., the volume at which water begins to flow from the second tank 422 to the first tank 421), such thatafter emptying of the second tank 422 by selectively actuating the actuator 470, water begins to flow from the second tank 422 to the first tank 421 before the first tank 421 can be emptied from its maximum volume.

According to the exemplary embodiment shown, the spring 678 and the check valve 684 are configured to allow rapid expulsion of water from the chamber 676, which enables the stopper 652 to quickly move from the closed position to an open position. The orifice 682 and the chamber 676 are configured to return the stopper 652 to the closed position over a period time. For example, the orifice size may be configured, based on the supply pressure of the water source 606, to provide a desired period of time. According to the exemplary embodiment, the period of time is approximately or slightly longer than the time for the water stored in the second tank 622 to stream out through the second plurality of holes. According to one embodiment, the period of time is substantially equal to the time for the water stored in the second tank 622 to stream out through the second plurality of holes. According to another embodiment, the period of time is between approximately 5 and 10 seconds. According to another embodiment, the period of time is between approximately 10 and 15 seconds. According to various embodiments, the actuator 670 begins to slowly move the stopper 652 towards the closed position while the second tank 622 is still draining. When the stopper 652 is closed, the second tank 622 begins refilling.
The interaction of the actuator 670 and the flow regulator 680 advantageously only requires plumbing of one supply line to the panel 602, enables automatic draining of the second tank 622 when the shower is turned off, enables simple push-button actuation by the user, eliminates the need to switch back to the rain feature after selecting the deluge feature.
Because the deluge feature is actuated when water flow to the actuators 470, 670 is ceased, the panel 400, 600 is automatically drained when water to shower is turned off. This allows the panel to dry out between uses and prevents cold water from remaining in the panel, which may be uncomfortable to the user during the next use. Further, as discussed above, the orifice 682 may be configured to slowly move the stopper 652 toward the closed position over a period of time. Thus, when the shower is turned on, cold water in the plumbing lines may be purged through the streaming holes until the stopper 652 reaches the closed position, thereby preventing the initial cold water from chilling the subsequent water and providing an uncomfortable showering/deluge experience.
According to various other embodiments, the hydraulic circuit and actuators 470, 670 may be reversed such that a flow of water into the chamber 476, 676 causes actuation of the deluge feature. For example, the chamber 476, 676 may be below the diaphragm 474, 674, which may be below the spring 478, 678, which in turn may be coupled to the shaft 477, 677 so as to push the stopper into a normally closed position. Accordingly, directing water into the chamber 476, 676 would cause water to pressurize the chamber 476, 676, pushing up on the diaphragm 474, 674, in turn compressing the spring 478, 678 and lifting the stopper 452, 652. A flow regulator having a check valve and orifice may be used to allow the chamber 476, 676 to slowly drain and return the stopper to a closed position. Water may be directed in to the chamber via, for example, a rotary or push button diverter valve.
Additional technologies are contemplated that may be used with any of the above embodiments, in whole or in part, and that may be used with the control system described below. For a first example, a vibrator may be coupled to the panel to cause the bottom wall to vibrate thereby causing for facilitating drops of water to fall from the panel. According to various embodiments, the vibrator may include an eccentric motor, a magnetostrictive transducer, or a piezoelectric transducer. According to one embodiment, the vibrator causes ultrasonic vibrations in the bottom wall of the panel. Instructions for controlling the vibrator may be stored in a vibration module in the memory of the processing electronics. For a second example, at least some of the holes through the bottom wall of the panel are fluidly coupled to a solenoid. According to one embodiment, a field of solenoids may cover the top surface of the bottom wall of the panel and push or spray water through the holes in the bottom wall. According to various embodiments, one solenoid may be fluidly coupled to one hole or one solenoid may be coupled to a plurality of holes. According to one embodiment, an array of solenoids may be fluidly coupled to a plurality of holes. Instructions for controlling the solenoid(s) may be stored in a solenoid module in the memory of the processing electronics. For a third example, a rotating foil having openings therethrough may be located above or below the bottom wall of the panel. For an embodiment with the foil below the bottom wall, the foil may impact the drops to slice the drops from the bottom wall or may create turbulence (e.g., pressure vortices, pressure disruptions, etc.) which break the drops from the bottom wall. The rotating foil on the bottom wall may provide a lateral force in the direction of rotation to the drops so that the drops may not fall vertically. A screen below the foil may prevent inadvertent contact with the foil and may rectify the direction of the drops. For an embodiment with the foil above the bottom wall, the alternating passage of foil and opening over the hole through the bottom wall may create pressure oscillations and/or cavitation, which facilitates the water breaking into drops.
Instructions for controlling the foil (e.g., the motor rotating the foil, etc.) may be stored in a foil module in the memory of the processing electronics.

The data stored in memory 264 may be stored according to a variety of schemes or formats. For example, the user input data may be stored in any other suitable format for storing information.
Memory 264 further includes configuration data 270. Configuration data 270 includes data relating to fluid control valve 202, sensors 208, control inputs 210 and display 214, and electric actuator 178. For example, configuration data 270 may include fluid control valve operational data, which may be data that flow control module 276 can interpret to determine how to command control circuit 260 to operate a flow control valve 202. For example, configuration data 270 may include information regarding flow rate information for various volume control valve 204 positions and mixed water temperature information for various mixing valve 206 positions. For example, configuration data 270 may include sensor operational data, which may be data that sensor module 274 can interpret sensor data from control circuit 260 into data usable by flow control module 276. For example, configuration data 270 may include voltage to temperature curves, or voltage to flow rate curves. For example, configuration data 270 may include display operational data which may be data that user interface module 272 or lighting module 284 can interpret to determine how to command control circuit 260 to operate a display 214.

Memory 264 further includes a flow control module 276, which includes logic for controlling the flow control valves 202. For example, flow control module 276 may include logic for processing sensor information (e.g., temperature, valve position, flow rate, etc.) from sensor module 274 and user input from user interface module 272 to provide commands to fluid control valves 202 over the control circuit 260. For example, a user may input a desired temperature into the control inputs 210, and the flow control module 276 may be configured to receive the input and provide one or commands to the flow control valves 202 to achieve the desired temperature, either via open-loop or closed-loop (e.g., using data from sensor module 274) control. For example, a user may input a desired flow rate or type of drops (e.g., small drops 20a, medium drops 20b, large drops 20c), and the flow control module 276 may be configured to receive the input and provide one or commands to the flow control valves 202 to achieve the desired flow rate, either via open-loop or closed-loop (e.g., using flow rate data or water depth in the reservoir 120 from sensor module 274) control. According to an exemplary embodiment, the flow control module 276 may process user input, in conjunction with configuration data 270, to cause a predetermined temporal pattern (e.g., cycle, sequence, etc.) of drops 20 to fall from the panel 102. For example, the flow control module 276 may include logic to cause the shower to begin as a light rain (e.g., small drops 20a), to progress to a moderate rain (e.g., including medium drops 20b), to progress to a downpour (e.g., including large drops 20c), and to end with a light rain (e.g., small drops 20a).
Memory 264 further includes a streaming module 278, which includes logic for controlling the streaming apparatus 150. For example, streaming module 278 may include logic for processing user input from user interface module 272 to provide commands to electric actuator 178 over the control circuit 260. The commands may cause the stopper 152 to move from the first position to the second position, from the second position to the first position, or anywhere in between. For example, the streaming module 278 may provide commands to the electric actuator 178 in response to data (e.g., a depth or height of water in the reservoir 120) received from the sensor module 274. According to one embodiment, the streaming module 278 may provide commands to the electric actuator 178 in response to a signal received from the flow control module 276 as part of causing the predetermined temporal pattern of drops 20. For example, the commands may cause the stopper 152 to move to the first position, or the commands may augment a downpour portion of the cycle with a deluge by moving the stopper 152 to the second position.
Memory 264 further includes a trajectory module 280, which includes logic for controlling the fan 218. For example, trajectory module 280 may include logic for processing inputs to provide commands to the fan 218. The inputs may be from the user interface module 272 or the flow control module 276. For example, the fan 218 may draw or push air to impart a lateral force onto the drops 20, thereby creating a more realistic trajectory (e.g., non-vertical) of the drops 20. The trajectory module 280 may provide commands that cause different fan speeds to create different trajectories of the drops 20 to help simulate, for example, different intensities of rainfall.
Memory 264 further includes an audio module 282, which includes logic for controlling the audio device 216. For example, the audio module 282 may include logic for distributing audio content received from audio device interface 244, or audible feedback indicia from another module in memory 264, to speakers in the showering area.

According to one embodiment, in response to instructions from the flow control module 276, the audio module 282 may provide commands to speakers in the showering area to simulate thunder while simulating a downpour.
Memory 264 further includes a lighting module 284, which may include logic for controlling the lights 212 and display 214. For example, the lighting module 284 may include logic for brightening or dimming the lights 212 and/or display 214 in response to user input from user interface module 272. The lighting module 284 may include logic for processing instructions from other modules in memory 264. For example, in response to instructions from the flow control module 276, the lighting module 284 may provide commands to cause the lights 212 to dim when simulating a downpour or to cause lights 212 to flash to simulate lightning.
Memory 264 further includes a scent module 286, which includes logic for controlling the scent emitters 220. For example, the scent module 286 may include logic for commanding the scent emitter 220 to provide a scent or aroma to the showering area in response to user input from user interface module 272 or in response to instructions from the flow control module 276. For example, the scent module 286 may include logic for commanding the scent emitter 220 to spray petrichor in the showering area while a low flow rate of water is flowing through the panel 102.
Memory 264 further includes a disinfecting module 288, which may include logic for controlling the disinfecting system 700. For example, the disinfecting module 288 may include logic for causing the disinfecting system 700 to disinfect at least a portion of the shower assembly 100 in response to user input from user interface module 272. For example, a user may press a button associated with a “Clean Now” label on the control inputs 210, and the disinfecting module 288 may provide commands to the disinfecting system 700 in response to receiving the input via the control inputs interface 238 and the control circuit 260. According to another embodiment, the disinfecting module 288 includes logic for activating and controlling the disinfecting system 700 on a schedule (e.g., weekly, monthly, etc.).
According to various embodiments of the shower assembly (e.g., 100, 200, 300, 400, etc.), the shower assembly is configured to be mounted to an overhead structure or ceiling (e.g., rafters, joists, framing, concrete, etc.). The shower system or assembly may also be configured, or include a mounting system, so as to be mounted to the overhead structure or ceiling, and then be adjusted into a final precise orientation relative to horizontal. For example, the shower assembly may require a specific orientation to ensure proper orientation of the panel (e.g., 102, 202, 302, etc.) and its bottom wall (e.g., 110, 210, 310, etc.) are level and/or to ensure proper water flow to the various outlet ports (e.g., 108, 208, 308, etc.). These mounting concepts are discussed in further detail below with respect to the embodiment of the shower assembly 1100, but are similarly applicable to the other embodiments of the shower assemblies disclosed herein.

The shower assembly 1100 also includes an upper wall or casing 1130 (e.g., wall, cover, top, shroud, etc.) that surrounds the sidewall 1116 of the panel 1102 and generally contains therein the tanks 1121, 1122, stopper 1152, and actuator 1170. The casing 1130 may provide a sealed upper surface or wall to prevent moisture from the chamber leaking upward into the building structure. The casing 1130 may further be configured couple to the panel 1102 to form a chamber with the reservoir 1120 in a manner that may substantially seal the chamber (other than the inlet 1106 and outlets 1108a, 1108b, 1108c, 1108d, other intentional water inlets or outlets, and any intentional air inlets or outlets), which may help further prevent moisture (e.g., steam from heated water received in the tanks 1121, 1122 of the reservoir 1120) from being released into the building structure to which the shower assembly 1100 is mounted. For example, the casing 1130 may include an outwardly protruding flange 1131 (e.g., horizontally extending) that is complementary to an outwardly protruding flange 1102a (e.g., horizontally extending) of the panel 1102 and is configured mate therewith. Fasteners 1133 (e.g., threaded fasteners, clips, etc.) couple the outwardly protruding flange 1102a of the bottom panel 1102 to the outwardly protruding flange 1131 of the casing 1130. A peripheral trim piece 1138 may be coupled to edges of the flanges 1102a, 1131 and/or between the flanges 1102a, 1131 (e.g., having a T- or L-shaped cross-section), so as to cover a seam or joint between the flanges 1102, 1131. Instead, or additionally, the shower assembly 1100 may include a seal 1132 (e.g., preferably a gasket, or alternatively a curable material, such as caulk), which is positioned (e.g., compressed) between the sidewall 1116 and a lower, peripheral surface of the casing 1130, so as to form a seal between the panel 1102 and the casing 1130. Alternatively or additionally, the trim piece 1138 may function as or include a seal (e.g., gasket and/or curable material) to form a seal between the panel 1102 and casing 1130. Furthermore, the casing 1130 may include a central vertical recess 1135 configured to receive the interior wall 1158 which may extend to a greater height than the sidewall 1116 and/or engage the casing 1130 at a greater height than that which the sidewall 1116 engages the seal 1132 and/or the casing 1130.
The shower assembly 1100 may also be configured to engage the building structure in an aesthetically pleasing and/or sealing manner. For example, the building structure may include a drop ceiling, such that framing and/or drywall define a recess in which the shower assembly 1100 is substantially positioned. The horizontal flange 1131 may engage a lower peripheral surface of the drop ceiling and may include a seal 1136 (e.g., gasket and/or curable material) positioned therebetween. The seal 1136 functions to seal the shower assembly 1100 against the building structure so as to prevent moisture (e.g., steam) from water released through the outlets 108a, 108b, 108c, 108d, or other moisture present in a showering enclosure or area, from reaching an interior of the building structure. According to other exemplary embodiments, the shower assembly 1100 may be configured to surface mount to a building structure and include a decorative shell or façade to hide otherwise exposed portions of the shower assembly 1100 from view (e.g., the casing 1130, plumbing, etc.).
As mentioned above, the mounting system 1140 is configured to mount the shower assembly 1100 to a building structure (e.g., framing, concrete, etc.), while providing for adjustment therebetween to achieve proper orientation (e.g., substantially horizontal lower surface of the panel 1102) of the shower assembly 1100, as may be required for proper flow of water to the outlets 108a, 108b, 108c, 108d. The mounting system may generally include a bracket 1141 configured to mount to the building structure, for example, with threaded fasteners 1142. The bracket mounting features, such as elongated studs 1143 (e.g., posts), are coupled to the bracket 1141 at predefined, non-adjustable locations that correspond with shower mounting features at non-adjustable shower mounting locations of the shower assembly 1100 In this manner, the bracket mounting features are positioned in the same fixed (i.e., predefined, non-adjustable) spatial relationship or orientation relative to each other, as are the shower mounting features of the shower assembly 1100 positioned relative to each other to facilitate alignment and coupling therewith. The elongated studs 1143 extend vertically downward from the bracket 1141 and may, for example, be supplied to a customer or installer already attached to the bracket 1141 or may be configured to couple to the bracket 1141 at the predefined locations (e.g., using holes, nuts, threads, etc.). While the bracket 1141 is depicted as being substantially H-shaped, so as to extend to four mounting locations, the bracket 1141 may have other shapes (e.g., L-shaped, triangular, rectangular) and extend to more or fewer mounting locations (e.g., 2, 3, 5, 6, etc.). According to other exemplary embodiments, the posts may be couple directly to the building structure without the bracket 1141, as opposed to being indirectly coupled to the building structure by way of the bracket 1141 as described previously.
The locations at which the threaded fasteners 1142 (i.e., for attaching the bracket 1141 to the building structure) are coupled to the bracket 1141 may substantially correspond to the mounting locations of the elongated studs 1143 (e.g., being positioned within approximately 1″ thereof) and/or may be positioned at other locations, for example, according to framing of the building structure. Moreover, the bracket 1141 may include multiple mounting locations for the fasteners 1142, for example, by providing holes for receiving the fasteners 1142 at various locations, not all of which may be used for a given installation.
The shower assembly 1100 and, in particular, the casing 1130, includes the shower mounting features that mate with the bracket mounting features of the mounting assembly 1140 on the bracket 1141. For example, the shower mounting features may be holes 1133 configured to receive the elongated studs 1143. For example, the casing 1130 may include holes 1133 through an upper surface thereof, which are in the same predefined, non-adjustable spatial orientation or relationship as the elongated studs 1143 to facilitate alignment and receipt of the elongated studs 1143 within the holes 1133. For example, the holes 1133 may be positioned in protrusions 1134 of the casing 1130 to accommodate other fastening components that allow for coupling, sealing, and/or adjustment.
The fastening components may generally include a fitting 1145 (e.g., level fitting), a seal 1146 (e.g., gasket), and a nut 1147. The fitting 1145 generally includes an upper flange 1145a, a shaft 1145b extending downward from the flange 1145a, and terminating at an end 1145c. The fitting 1145 also includes a central bore 1145d extending therethrough from the flange 1145a, through the shaft 1145b, and to the end 1145c. Each fitting 1145 is configured as a female member that receives one of the studs 1143 acting as a male member therein and is adjustably coupled to with the stud 1143 via complementary threads (i.e., each stud 1143 is threaded on an outer surface thereof, and the bore 1145d is internally threaded to receive the threads of the stud 1143, such that the position of the fitting 1145 may be adjusted relative to the stud 1143). As the fitting 1145 is vertically adjustable on the stud 1143, the flange 1145a forms an adjustable upper limit against which the casing 1130 may be positioned. Each fitting 1145 is additionally positioned in one of the holes 1133 of the casing 1130 with the flange 1145a being positioned above the casing 1130 and the shaft 1145b extending through the hole 1133. Each stud 1143 may, by virtue of extending through the bore 1145d of the fitting, also extend through the holes 1133 of the casing 1130. The seal 1146 is received on the fitting 1145 and is positioned against a lower surface of the casing 1130. The nut 1147 is adjustably received on the shaft 1145b (e.g., the nut 1147 has internal threads that are complementary to external threads of the shaft 1145b), so as to compress the seal 1146 and the casing 1130 between the nut 1147 and the flange 1145a of the fitting. The seal 1146 may instead be provided as a portion of the nut 1147 (e.g., as a single unit), such that the seal 1146 is compressed against the casing 1130 around the hole 1133. The mounting system may further include a washer 1148, which may be provided as a separate component or as part of a single unit with the seal 1146, that distributes force from the nut across the seal 1146. In this manner, the holes 1133 may be sealed, as discussed above, to prevent moisture from the tanks 1121, 1122 reaching an interior of the building structure. The end 1145c may, for example, have a hex head to allow tightening of the nut 1147 on the fitting 1145 using conventional tools (e.g., the hex head and the nut 1147 being moved and/or held with a wrench). For casings 1130 that include a protrusion 1134 (as shown), the shaft 1145b of the fitting 1145, the seal 1146, the nut 1147, and the stud 1143 may all be positioned within the protrusion 1134. According to other exemplary embodiments, the stud or post 1143 may be configured as a female member (e.g., a nut, an internally threaded tube, etc.) that is configured to receive the fitting 1145, which is instead configured as a male member (e.g., externally threaded).
A method for mounting the shower assembly 1100 (or any of the previously described shower assemblies) using the mounting system 1140 is contemplated. In a first step, the building structure is prepared for mounting the shower assembly 1100, which may include installation of plumbing to provide a water source to the shower assembly 1100, and in appropriate installations, preparation of a drop ceiling to provide a recess in which the shower assembly may be positioned. Furthermore, during the first step, all finishing of the drop ceiling and/or other building structures may be completely finished prior to installation of the shower assembly 1100, since all additional steps for mounting and connecting the shower assembly 1100 occur from within the recess of the building structure or from within the shower assembly 1100 itself.
In a second step, the bracket 1141 is coupled to the building structure. For example, in applications using conventional framing, threaded fasteners 1142 (e.g., drywall or wood screws) are inserted through holes in the bracket 1141 at locations corresponding to suitable coupling locations of the building structure (e.g., at joist positions). In applications where the building structure is concrete, other threaded fasteners 1143 suitable for use with concrete are inserted through holes in the bracket 1141 for coupling to the building structure.
In a third step, the fittings 1145 (e.g., four fittings 1145 corresponding to the four holes 1133 of the casing 1130) are coupled to the studs 1143, and then adjusted to a final height (e.g., by threading). The predefined orientation of the shower assembly 1100 (e.g., having a substantially level bottom surface) requires that all fittings 1145 be substantially level with each other (e.g., within approximately 1 degree of horizontal, and/or within a range of ½ in elevation). The proper height also requires that the shower assembly 1100 be positioned at a proper elevation relative to the building structure (e.g., such that the seal 1136 is compressed between the shower assembly 1100, such as the flange 1131 of the casing 1130, and the building structure). Instead, or additionally, the fittings 1145 may be adjusted to a rough height (e.g., by threading) allowing a greater degree of variation between the fittings 1145 relative to level. Whether initially adjusting to a final or a rough height, the height of the fittings 1145 may be further adjusted after the shower assembly 1100 is coupled to the mounting assembly 1140, as described below.
In a fourth step, the shower casing 1130 is coupled to the mounting assembly 1140. During the fourth step, the panel 1102 is removed from the shower casing 1130, or the panel 1102 may be initially provided decoupled from the casing 1130. The shower casing 1130 is raised and positioned, so as to insert the shaft 1145b of each fitting 1145 into the holes 1133 of the casing. Each seal 1146 is then placed on one of the shafts 1145b, which is followed by one of the nuts 1147 being threaded onto the shaft 1145b. The nuts 1147 are then tightened on the shaft 1145b, so as to compress the casing 1130 and the seal 1146 between the flange 1145a of the fitting 1145 and the nut 1147, so as to fixedly couple the casing 1130 to the mounting system 1140 and to seal the holes 1133 of the casing 1130. More particularly, the hex head end 1145d is held in a fixed position (e.g., with an open ended wrench), while the nut 1147 is rotated on the shaft 1145b (e.g., with another open ended wrench). If any of the fittings 1145 require height adjustment on the studs 1143, for example because they moved out of their final position, were initially placed in a rough position, or were otherwise initially placed out of position, each fitting 1145 may be adjusted by rotating the fitting 1145 on the stud 1143, for example, by using a wrench that engages the hex head end 145d of the fitting. Prior to such adjustment, it may be necessary to loosen the nut 1147, so as to less the compression and friction between the fitting 1145, seal 1146, and the casing 1130 and allow rotation therebetween. After such adjustment, it may be necessary to then again tighten the nut 1147, so as to recompress the casing 1130 and seal 1146 between the fitting 1145 and nut 1147. During the fourth step, the seal 1136 may also be positioned on the flange 1131 of the casing, such that when the casing 1130 is coupled to the mounting system 1140 and raised to its final position, the seal 1136 is compressed between the building structure and the flange 1131. During the fourth step, the inlet 1106 of the shower assembly may also be coupled to the plumbing of the building (i.e., a water source).
In a fifth step, the panel 1102 is coupled to the casing 1130. The panel 1102 is raised and positioned relative to the casing 1130, such that their respective outwardly extending flanges 1102a, 1131, are aligned and brought into contact with each other or the trim piece 1138 or seal is compressed therebetween. The fasteners 1137 are then inserted and tightened, so as to couple the panel 1102 to the casing 1130 and complete installation of the shower assembly 1100. It should also be noted that the inner wall 1158, stopper 1152, and/or actuator 1170 may be provided with, and therefore, installed with the casing 1130. When so configured, when the panel 1102 is raised and positioned relative to the casing 1130, the interior wall 1158 is brought into contact (e.g., sealing contact) with a top surface of the panel 1102, so as to divide the reservoir 1120 into the first tank 1121 and the second tank 1122. In this manner, the interior wall 1158 is coupled to the panel 1102 by virtue of the panel 1102 being coupled to the casing 1130.
The construction and arrangement of the systems and methods as shown in the various exemplary embodiments are illustrative only. Although only a few embodiments have been described in detail in this disclosure, many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, orientations, etc.). For example, the position of elements may be reversed or otherwise varied and the nature or number of discrete elements or positions may be altered or varied. Accordingly, all such modifications are intended to be included within the scope of the present disclosure. The order or sequence of any process or method steps may be varied or re-sequenced according to alternative embodiments. Other substitutions, modifications, changes, and omissions may be made in the design, operating conditions and arrangement of the exemplary embodiments without departing from the scope of the present disclosure.
The present disclosure contemplates methods, systems and program products on any machine-readable media for accomplishing various operations. The embodiments of the present disclosure may be implemented using existing computer processors, or by a special purpose computer processor for an appropriate system, incorporated for this or another purpose, or by a hardwired system. Embodiments within the scope of the present disclosure include program products comprising machine-readable media for carrying or having machine-executable instructions or data structures stored thereon. Such machine-readable media can be any available media that can be accessed by a general purpose or special purpose computer or other machine with a processor. By way of example, such machine-readable media can comprise RAM, ROM, EPROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to carry or store desired program code in the form of machine-executable instructions or data structures and which can be accessed by a general purpose or special purpose computer or other machine with a processor.
