Filtered showerhead with multiple nozzle assemblies

Abstract

A multi-mode showerhead having a housing with a front and a rear and an offset integrated water filter system incorporated into the showerhead. The multi-mode offset filtered showerhead has multiple nozzle assemblies, one of which is movable or rotatable and another of which is removable and may contain a unit to hold a water filter cartridge for insertion and removal from the integrated water filter system incorporated into the showerhead. A selector switch and other water flow control devices are used to selectively control the flow of water through the showerhead to the nozzle assemblies. The showerhead is mounted on a shower arm by way of a single water inlet on the rear of the housing and is fluidly connected to a hollow filter chamber in the integrated water filter system.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

(14) The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes contemplated by the inventor of carrying out his invention. Various modifications, however, will remain readily apparent to those skilled in the art, since the generic principles of the present invention have been defined herein specifically to provide for a multi-mode showerhead having an offset integrated water filter assembly and multiple shower spray nozzle assemblies.

(15) The multi-mode showerhead having multiple spray nozzle assemblies (or spray-heads) and an offset integrated water filter system of the present invention is mounted directly on a regular shower arm coming out of a shower wall (not shown), and is normally screwed onto or otherwise sealingly secured to the shower arm and extending into a shower area.

(16) Turning now to the drawings, FIGS. 1-8 illustrate a currently preferred embodiment of a multi-mode showerhead 10 having an offset integrated water filter system incorporated in the showerhead. The showerhead 10 includes a multi-piece hollow main body or housing 12 with a rear face, portion, or surface 14 and a front face, portion, or surface 16. The body 12 has a single water inlet 18, which is preferably movable, and a plurality of water outlets having spray nozzle assemblies therein. The body is substantially hollow or incudes passages for water therein and could, if desired include additional nozzles. As shown, the housing 12 has a first spray nozzle assembly 20 removably held in the front face 16 at a first end 22 of the showerhead 10. This first spray nozzle assembly 20 is mechanically fixed in place in a hollow chamber 23 formed in the showerhead comprising part of the water filter system, but may be removed, as needed, to replace a filter cartridge, as explained more fully below.

(17) A second movable spray nozzle assembly or water outlet 24 is rotatably held in a pair of hollow arms 26, 28, at a second end of the showerhead. The arms 26, 28, could, of course, be extended outwardly until they form a complete surround for the rotatable nozzle assembly 24, without interfering in its movement. The second spray nozzle assembly 24 is substantially hollow (see FIGS. 11 and 12) with a plurality of openings 30 on one side thereof, located so that they face into a shower area when the showerhead is mounted on a shower arm. Additionally, the second spray nozzle assembly includes a pair of hollow bearing arms 32, 34 on opposed sides thereof which are sealing held in the hollow arms 26, 28 to allow the second spray nozzle assembly to be rotated and water to enter the nozzle assembly 24 and exit through the openings 30 (see FIGS. 4, 5 and 7.) The pair of hollow bearing arms 32, 34 allow the second spray nozzle assembly to be easily and sealingly rotated in the hollow arms 26, 28 by a user, to selectively change the direction of the flow of filtered water from the second spray nozzle assembly (see FIG. 8.)

(18) A substantially hollow mode selector switch or knob 36 is held in a central portion of the front face 16 (see FIGS. 2-4, 7, 8, 11 and 12), between the first and second nozzle assemblies 20 and 24 to control flow of water to the second nozzle assembly 24.

(19) As shown in FIGS. 9-12, the first nozzle assembly 20 is releasably or removably held in the hollow chamber 23 in the first end 22 of the body or housing 12. The first nozzle assembly 20 is shown with a water filter cartridge holding unit 38 secured thereto. The unit 38 has a screw off cap or top 40 which covers a removable holding element 42. A filter cartridge 44, shown in broken line, is inserted and held in a hollow interior 45 of holding element 42. This removable holding element 42 has a plurality of openings 43 formed therethrough to allow water to flow through the filter cartridge. Therefore, when first nozzle assembly and holding unit 38, with a filter cartridge held therein, is inserted and held in the hollow chamber 23 it forms the water filter system through which water entering through the inlet 18 flows before it exits through the first nozzle assembly 20, and/or through the moveable second nozzle assembly 24.

(20) As best shown in FIG. 12, when the showerhead 10 of the present invention is properly assembled with the hollow threaded inlet 46 in cap 40 holding the first spray nozzle 20 and cartridge holding unit in place and then mounted on a shower arm (not shown), in any known manner, water enters from the shower arm through the inlet 18 and flows through the hollow threaded inlet 46 in cap 40, through the filter cartridge 44.

(21) First, if all the water flow control devices, including selector switch 36 are adjusted, water entering the showerhead from the shower arm goes through the filter cartridge 44 and through the first nozzle assembly 20, if not blocked by actuation of lever 48 and a plurality of plates 50 having openings therein secured to the lever, as described in the '565 application. Additionally, water, after passing through the filter cartridge 44, will flow through openings in the wall of hollow chamber 23 toward the selector switch 36. The selector switch 36 may be adjusted to block flow, or to preferably allow the water to flow into the second nozzle assembly 20 and out through the outlets 30.

(22) It is to be understood that, if desired, the water filter cartridge holding unit 38 may be eliminated and the first nozzle assembly 20 modified to be similar to the water filter system set forth in the '565 application or this nozzle assembly may be provided with a different type holding where the filter cartridge 44 may be placed for insertion into the hollow chamber 23,

(23) It, therefore, can be seen that the present invention provides an improved, less cumbersome, easy to install and use multi-mode showerhead having multiple nozzle assemblies, in a substantially hollow housing with an offset integrated water filter assembly providing an integrated design.

(24) Those skilled in the art will appreciate that various adaptations and modifications of the just-described preferred embodiment may be configured without departing from the scope and spirit of the invention. Therefore, it is to be understood that, within the scope of the appended claims, the invention may be practiced other than is specifically described herein.
