Abstract
A showerhead is provided having a housing, a perforate partition and a nozzle body. The housing has a fluid inlet and a fluid outlet. The perforate partition is provided in the housing between the inlet and the outlet and has at least one peripheral fluid passage communicating with the fluid inlet. Each peripheral fluid passage communicates at a downstream end with an inwardly extending peripheral slot, and each slot communicates at a downstream end with a mixing cavity. The nozzle body is carried by the housing downstream of the mixing cavity and has a compression port at an upstream end and an outlet port at a downstream end in fluid communication with the compression port.
Claims41
A showerhead, comprising:
- a housing having a fluid inlet and a fluid outlet;
- a circumferential mixing hub having a baffle, a plurality of axially extending peripheral ports in the baffle upstream and in fluid communication with a plurality of radially inwardly extending passages, at least one of the passages extending at an angle relative to a radial direction to a central mixing chamber so as to impart one of a clockwise and a counterclockwise direction mixing and swirling of water within the mixing chamber;
- a nozzle body downstream and coaxial with the central mixing chamber having an outer circumferential surface configured to receive swirling fluid from the central mixing chamber and defining at least in part an annular swirling cavity having an upstream portion greater in cross sectional area than a downstream portion;
- a fastener affixed to the hub coaxially within the circumferential swirling cavity to provide a center support post carried by the hub centrally of the central mixing chamber and the annular swirling cavity;
- and
- a rotor carried for rotation about the fastener coaxially within the nozzle body having an inner circumferential surface of the annular swirling cavity and at least one fluid ejecting outlet aperture spaced radially outwardly of a central axis of the fastener and angled relative the central axis to impart spin to the rotor responsive to fluid ejecting from the at least one outlet.
A showerhead, comprising:
- a housing having a fluid inlet and a fluid outlet;
- a circumferential mixing hub having a plurality of axially extending peripheral ports in the hub upstream and each port provided in fluid communication with a respective passage extending radially inwardly, at least one passage provided at an angle relative to a radial direction to a central mixing chamber so as to impart one of a clockwise and a counterclockwise direction mixing and swirling of water within the mixing chamber;
- a nozzle body carried by the housing downstream of the mixing chamber having an annular swirling cavity downstream of the central mixing chamber having an inlet end greater in cross sectional area than a downstream cross sectional area;
- a center support post carried by the hub centrally of an outlet chamber and through a flow concentrating outlet;
- and
- a rotor carried for rotation coaxial and downstream of the nozzle body by the center support post and having an inner circumferential surface of the annular swirling cavity and at least one fluid ejecting outlet aperture spaced radially outwardly of a central axis of the rotor and angled relative the central axis to impart spin to the rotor responsive to fluid ejecting from the at least one outlet.
