Abstract
A showerhead is either wall mounted or provided with a handle connected through a flexible hose to an incoming water outlet. The showerhead has a turbine which may cause the delivery of pulses of circumferentially distributed groups of pulses of water so as to provide either fast or slow massage action. Also included is a pause mode in which flow is reduced without complete shutoff and a center spray mode which provides a concentrated spray pattern. Other modes possible are a needle spray, a combination pulse and needle spray, a combination needle spray with a body spray, just a body spray, and an oval shape spray pattern. Various water paths are defined from a flow selector through the unit to different ones of front-facing orifices as defined for the different modes. Selection is achieved by a combination of a flow director and a control plate. User access for mode selection is by way of an external circumferential control ring operatively coupled to the control plate through a control arm. A component is removable by the user to enable easy cleaning of an array of the outlet orifices.
