Abstract

A shower head for a hand-held shower attachment contains, in the center of its jet disc, an insert with three individual nozzle bodies. Each individual nozzle body is designed for discharging an individual jet. To this end, it has a continuous jet opening. Each of these in individual nozzle bodies is mounted in a manner that enables it to move relative to the shower head and to the jet disc, and is placed in rotation by a water-driven rotor. Said continuous jet opening extends at an angle to the rotation axis of the individual nozzle body. When the individual nozzle body rotates, the jet exiting there from moves on an envelope of a cone. Each individual nozzle body, contains an aerating device that aspirates the air immediately next to the outlet opening and, inside the individual nozzle body, mixes the air with the water entering this individual nozzle body. As a result, the individual nozzle body discharges an aerated jet.

Claims

1. A showerhead for a sanitary fitting, comprising:

a showerhead housing, a water inlet line defined in the showerhead housing, a jet disc configured for at least one jet outlet provided with water from the water inlet line, at least an individual nozzle body held movably relative to at least one of the jet disc and the showerhead housing, wherein the individual nozzle body has its own aeration device only for aerating a shower jet exiting from said individual nozzle body, and wherein the individual nozzle body is driven forcibly to move, by a turbine;

wherein the aeration device of the individual nozzle body includes an air channel opening at a front face on the exit side of the individual nozzle body and running through the individual nozzle body; and

, wherein the air channel runs parallel to a jet channel of the nozzle body and has a smaller cross-section than the jet channel.

2. The showerhead according to claim 1, wherein the individual nozzle body is held in said at least one of the showerhead housing and the jet disc.

3. The showerhead according to claim 1, wherein the individual nozzle body is held in an insert of the showerhead housing.

4. The showerhead according to claim 1, wherein the individual nozzle body is held so as to be freely movable.

5. The showerhead according to claim 1, wherein the individual nozzle body is configured such that the shower jet exiting from the individual nozzle body changes its direction relative to the showerhead during motion of the individual nozzle body.

6. The showerhead according to claim 1, wherein the air channel discharges into a mixing chamber of the individual nozzle body.

9. The showerhead according to claim 1, wherein the aeration device comprises several air channels distributed around a jet channel of the shower jet.

12. The showerhead according to claim 1, wherein the at least one individual nozzle body is usable concurrently with further jet outlet elements.

13. The showerhead according to claim 12, wherein the individual nozzle body jets in a same direction as the further jet outlet elements of the jet disc.

14. The showerhead according to claim 1, wherein the individual nozzle body is driven rotationally by the water from the water inlet line, passing through the turbine.

7. A showerhead for a sanitary fitting, comprising:

a showerhead housing, a water inlet line defined in the showerhead housing, a jet disc configured for at least one jet outlet provided with water from the water inlet line, at least an individual nozzle body held movably relative to at least one of the jet disc and the showerhead housing, wherein the individual nozzle body has its own aeration device only for aerating a shower jet exiting from said individual nozzle body, and wherein the individual nozzle body is driven forcibly to move, by a turbine;

wherein the aeration device of the individual nozzle body includes an air channel opening at a front face on the exit side of the individual nozzle body and running through the individual nozzle body;

wherein the air channel discharges into a mixing chamber of the individual nozzle body; and

, wherein the mixing chamber is bound upstream by a distributing plate with several holes.

8. The showerhead according to claim 7, wherein the distributing plate lies on a step in the individual nozzle body, underneath of which at least one air channel discharges.

10. A showerhead for a sanitary fitting, comprising:

a showerhead housing,

a water inlet line defined in the showerhead housing,

a jet disc configured for at least one jet outlet provided with water from the water inlet line,

plural individual nozzle bodies, each of said individual nozzle bodies being held movably relative to at least one of the jet disc and the showerhead housing, wherein each said individual nozzle body has its own aeration device only for aerating a shower jet exiting from said individual nozzle body, wherein the plural individual nozzle bodies are driven forcibly to move by a turbine; and

wherein the aeration device of each said individual nozzle body includes an air channel opening at a front face of the individual nozzle body and running through the individual nozzle body.

11. The showerhead according to claim 10, wherein several of the individual nozzle bodies are configured to be driven concurrently.
