DETAILED DESCRIPTION OF THE DRAWINGS

(9) The embodiments of the invention described herein are not intended to be exhaustive or to limit the invention to precise forms disclosed. Rather, the embodiments selected for description have been chosen to enable one skilled in the art to practice the invention.

(10) Referring initially to FIG. 1, an illustrative showerhead assembly 10 includes a front faceplate 12 coupled to a rear housing 14. A plurality of scanner nozzles 16 are supported by the faceplate 12. A fluid connector 18 is supported by the rear housing 14 and is configured to be fluidly coupled to a pressurized water source 20, such as a shower pipe supported within a wall (not shown).

(11) With reference to FIGS. 2 and 3, the front faceplate 12 illustratively includes a body 22 having a front surface 24 and a rear surface 26. The front faceplate 12 may be coupled to the rear housing 14 through conventional means, such as screws 27. Alternatively, ultrasonic welding, adhesives, etc. may be substituted for the screws 27. An o-ring 29 may be positioned intermediate the front faceplate 12 and the rear housing 14 to provide sealing therebetween.

(12) A longitudinal faceplate axis 28 illustratively extends perpendicular to the front surface 24 of the front faceplate 12. A plurality of stepped bores 30 extend through the body 22 from the front surface 24 to the rear surface 26, each along a longitudinal bore axis 32. As shown in FIG. 3, the stepped bores 30 illustratively are arranged into an outer ring of stepped bores 30A and an inner ring of stepped bores 30B.

(13) The longitudinal bore axis 32 is illustratively positioned at an angle to the longitudinal faceplate axis 28 (FIG. 4) to provide increased spray pattern coverage. In one illustrative embodiment, the longitudinal bore axis 32 is positioned at an angle as little as 0°, 2°, 4°, as great as 6°, 8° or 10° to the longitudinal faceplate axis 28. In one illustrative embodiment, the longitudinal bore axis 32A for an outer ring of stepped bores 30A (FIG. 3) is positioned at an angle to the longitudinal faceplate axis 28 different than the angle of longitudinal bore axis 32B for an inner ring of stepped bores 30B to the longitudinal faceplate axis 28. Illustratively, the longitudinal axis 32A for the outer ring of stepped bores 30A is positioned at a relatively larger angle, such as an angle of 8° to the longitudinal faceplate axis 28, and the longitudinal axis 32B for the inner ring of stepped bores 30B is positioned at a relatively smaller angle, such as an angle of 4°, to the longitudinal faceplate axis 28.

(14) Each stepped bore 30 includes angled sidewalls 34, 36, 38. A plurality of steps or lips 40 and 42 extend between sidewalls 34, 36 and 36, 38 and face rearwardly toward the rear surface 26.

(15) Illustratively, the body 22 of the faceplate 12 is molded from a polymer. The sidewalls 34, 36, 38 illustratively flare outwardly (are angled away from the bore axis 32 as the sidewalls 34, 36, 38 extend from the front surface 24 to the rear surface 26. This arrangement assists in manufacturing by permitting injection molding without requiring complex tool action. In other words, pins within the injection molds may be easily removed due to the tapered walls 34, 36, 38.

(16) Each of the scanner nozzles 16 illustratively includes an upstream end member 46 and a downstream end member 48 defining an oscillation chamber 50. Additional details on an illustrative scanner nozzle are provided in U.S. Pat. No. 6,938,835 to Stouffer, the disclosure of which is expressly incorporated by reference herein.

(17) The upstream end member 48 of each scanner nozzle 16 is illustratively formed of a polymer, and includes a screen or filter 60 configured to contact a front surface 62 of the rear wall 64 of the rear housing 14. Illustratively, the rear wall 64 of the housing includes a plurality of engagement portions 66 angled relative to the front surface 24 of the face plate 12. In other words, the engagement portions 66 are perpendicular to the bore axis 32. Each engagement portion 66 contacts the upstream end member 46 of a scanner nozzle 16.

(18) The downstream end member 48 of each scanner nozzle 16 is illustratively formed of an elastomer or a polymer, and is illustratively coupled to upstream end member 46 through conventional means, such as ultrasonic welding or adhesives. Each downstream end member 48 illustratively includes a plurality of forwardly facing steps or lips 70, 72 configured to cooperate with the steps 40, 42 of the bore 30. An o-ring 74 is illustratively received intermediate the step 40 of the bore 30 and the step 70 of the scanner nozzle 16. As may be appreciated, when the faceplate 12 is coupled to the rear housing 14, the rear wall 64 contacts the rear end of the upstream end member 46 such that the o-ring 74 is compressed and the scanner nozzle 16 secured in place by the cooperating steps 40, 42, 70, 72.

(19) The water source 20 is fluidly coupled to the showerhead assembly 10 through fluid connector 18. With reference to FIG. 3, the fluid connector 18 illustratively includes a shower ball 76, a screw ring 78 and a gasket 80. The shower ball 76 permits rotational movement of the showerhead 10 about orthogonal axes. A screen 81 or a flow restrictor may be provided to limit the flow rate of water from the water source 20 into the showerhead assembly 10.

(20) In the further illustrative embodiment showerhead assembly 10 of FIG. 5, the plurality of scanner nozzles 16 may be integrally molded within the faceplate 12. More particularly, the upstream end member 46 may be molded into an upper or inner faceplate member 82 thereby defining the inlet aperture 52 and the first or upper hemisphere 56 of the oscillation chamber 50. Similarly, the downstream end member 48 may be molded into a lower or outer faceplate member 84 thereby defining the outlet aperture 54 and the second or lower hemisphere 58 of the oscillation chamber 50. The inner faceplate member 82 and the outer faceplate member 84 may be molded separately and then secured together using conventional means, such as ultrasonic welding or adhesives. Alternatively, the inner faceplate member 82 and the outer faceplate member 84 may be secured using screws, snaps, or hotplate welding. In the illustrative embodiment, the outlet aperture 54 is angled relative to the faceplate 12, and includes a conical shape larger at the end adjacent to the lower hemisphere 58. Illustratively, the angled outlet apertures 54 are molded as part of faceplate member 84.

(21) Referring now to FIG. 7, a further illustrative showerhead assembly 110 illustratively includes a first fluid dispensing unit 112 and a second fluid dispensing unit 114 removably coupled to the first fluid dispensing unit 112. Illustratively, the first fluid dispensing unit 112 comprises a fixed showerhead, while the second fluid dispensing unit 114 comprises a handshower. The handshower 114 removably couples or docks with the fixed showerhead 112. Illustratively, a magnet 116 attracts a member 118 to hold the handshower 114 relative to the showerhead 112. Water source 20 provides water to the fixed showerhead 112 and the movable handshower 114.

(22) In the illustrative embodiment of FIG. 2, the fixed showerhead 112 includes an arcuate housing 144 defining a center recess or opening 146 to receive the handshower 114. A flow restrictor (now shown) may be supported proximate a rear end of the fixed showerhead 112 and is configured to limit the rate of water flow therethrough to no more than a predetermined value. In one illustrative embodiment, the flow restrictor limits the water flow rate to no more than 2.5 gallons per minute (gpm). In another illustrative embodiment, the flow restrictor limits flow rate to no more than 2.0 gallons per minute (gpm) in accordance with the WaterSense Specification for Showerheads as released by the U.S. Environmental Protection Agency on Mar. 4, 2010 (available at the website http://www.epa.gov/watersense/docs/showerheads_finalspec508.pdf). A diverter valve 120 may also be supported by the fixed showerhead 112 and is configured to provide selective or combined water flow to either or both of the fixed showerhead 112 and the handshower 114.

(23) A first plurality of scanner nozzles 166a are supported by the fixed showerhead 112. A second plurality of scanner nozzles 166b are supported by the handshower 114. The scanner nozzles 166a and 166b, and associated assembly within the fixed showerhead 112 and the handshower 114, may be substantially similar to that detailed above in connection with showerhead assembly 10.

(24) Although the invention has been described in detail with reference to certain preferred embodiments, variations and modifications exist within the spirit and scope of the invention as described and defined in the following claims.
