Abstract

A shower head jet disk ( 4 ) has inlet and outlet openings ( 8, 9 ) on opposite sides, with a passage duct ( 10 a, 10 b ) fluidically connecting each outlet to at least one inlet. An upstream control disk ( 2 ) is rotatable relative to the jet disk and has a control slot pattern ( 131, 134 ) opening the inlets depending on the rotational position of the control disk. The control slot pattern and the inlets are coordinated such that two adjacent inlet openings ( 8 a, 8 b ) that correspond with a common outlet opening ( 9 ) via two passage ducts ( 10 a, 10 b ) with non-parallel side walls ( 12 a, 12 b ) provide different jet outlet directions (Sa, Sb), or two regions of an inlet opening that corresponds with an outlet opening via a passage duct with non-parallel side wall regions provide different jet directions, or two adjacent inlet openings that correspond with two adjacent outlet openings are opened, in alternating fashion.

First claim

The invention claimed is:

1. A shower head for a sanitary shower device, comprising:
a jet disk having inlet openings on one side of the jet disk and outlet openings on an other side of the jet disk and having in each case a passage channel connecting each said outlet opening to at least one said inlet opening, through which passage channel fluid can flow through the jet disk, and
a control disk arranged upstream of the jet disk in a fluid flow direction, the control disk being rotatably movable relative to said jet disk, wherein the control disk has a control slot pattern having control slots through the control disk, wherein the control slots become aligned with the inlet openings, thereby connecting flow to the inlet openings, and become misaligned to block flow to the inlet openings, depending on a rotary position of the control disk,
wherein the control slot pattern and the inlet openings are matched to one another in position such that during rotation of the control disk relative to the jet disk, alternating alignment and misalignment of the control slots and the inlet openings at different rotary positions of the control disk selects flow through different passage channels of pairs of passage channels that have at least one of adjacent inlet openings and adjacent outlet openings on the jet disk.

2. The shower head according to claim 1 , wherein openings of the pairs of passage channels are adjacent to one another at different radial distances on the jet disk and the control slot pattern includes slot regions correspondingly disposed at said different radial distances.

3. The shower head according to claim 2 , wherein the control slot pattern comprises at least two separate slot segments disposed at said different radial distances, which slot segments are assigned in each case to one of said openings of the pairs of passage channels.

4. The shower head according to claim 3 , wherein the control slot pattern comprises a slot that is continuous in a circumferential direction and bridged by one of at least one bridge web, and slots extending in the circumferential direction and separated from one another by at least one separation web.

5. The shower head according to claim 1 , wherein at least one said passage channel has a cross-section tapering conically towards the outlet opening in a jet disk radial plane.

6. The shower head according to claim 1 , wherein the control disk is provided with a fluid flow driven turbine blade structure on an inlet side facing away from the jet disk.

7. The shower head according to claim 6 , wherein the control slot pattern is radially outside of the turbine wheel.

8. The shower head according to claim 6 , further comprising a planetary gearing having a sun wheel provided on the turbine wheel, an outer hollow wheel provided on the control disk, and a planetary wheel interposed therebetween.

9. The shower head according to claim 1 , further comprising a blocking mechanism for blocking the control disk rotary movement in one of a first blocking position in which one of said two adjacent inlet openings is enabled, and a second blocking position in which the other said inlet opening is enabled.

10. The shower head according to claim 9 , wherein the blocking mechanism includes a blocking pin movably attached to the jet disk, which blocking pin is successively switchable between at least three different positions, of which a first position enables rotary movement of the control disk, a second position defines the first blocking position, and a third position defines the second blocking position.

11. The shower head according to claim 3 , wherein the slot segments include at least one slot extending in the circumferential direction and radial direction of the control disk, which slot is assigned to both of said openings of the pairs of passage channels.

12. The shower head according to claim 2 , wherein the control slot pattern comprises at least two separate slot segments disposed at different radial distances, which slot segments include at least one slot extending in a circumferential direction and a radial direction of the control disk, which slot is assigned to both of said openings of the pairs of passage channels.

13. The shower head according to claim 1 , wherein the control disk is coupled to a fluid flow driven turbine wheel via a gearing, which turbine wheel and gearing are arranged on a side of the control disk facing away from the jet disk.

14. The shower head according to claim 13 , wherein the control slot pattern is radially outside of the gearing.

15. The shower head according to claim 13 , wherein the gearing comprises a planetary gearing having a sun wheel provided on the turbine wheel, an outer hollow wheel provided on the control disk, and a planetary wheel interposed therebetween.

16. A shower head for a sanitary shower device, comprising:
a jet disk having at least one inlet opening on one side of the jet disk and at least one outlet opening on an other side of the jet disk and having in each case at least one passage channel connecting each said outlet opening to at least one said inlet opening, through which passage channel fluid can flow through the jet disk, and
a control disk arranged upstream of the jet disk in a fluid flow direction, the control disk being rotatably movable relative to said jet disk, wherein the control disk has a control slot pattern having control slots through the control disk, wherein the control slots become aligned with the inlet openings thereby connecting flow to the inlet openings, depending on a rotary position of the control disk,
wherein the control slot pattern and the inlet openings are matched to one another such that during rotation of the control disk relative to the jet disk, alternating alignment and misalignment of the control slots and the inlet openings at different rotary positions of the control disk selects flow through passage channels at different radial distances, and
wherein the passage channels of the pairs of passage channels include passage channels with nonparallel sidewalls, respectively coupling said inlet and outlet openings such that an opening on one of an inlet and outlet side of the jet disk couples to an opening on an opposite of the inlet and outlet side of the jet disk such that the passage channels with nonparallel sidewalls alternately emit in two different jet outlet directions.

17. The shower head according to claim 1 , wherein the alignment and misalignment of the control slots and the inlet openings at different rotary positions of the control disk includes rotary positions at which one of the control slots aligns with only one of two adjacent inlet openings coupled with one common outlet opening via two passage channels having non-parallel side walls, thereby selecting one of two different jet outlet directions.

18. The shower head according to claim 1 , wherein the alignment and misalignment of the control slots and the inlet openings at different rotary positions of the control disk includes rotary positions at which one of the control slots aligns with a region of an inlet opening for directing flow at one of two different jet outlet directions through an outlet opening, through a passage channel having non-parallel side wall regions.

19. The shower head according to claim 1 , wherein the alignment and misalignment of the control slots and the inlet openings at different rotary positions of the control disk includes rotary positions at which one of the control slots aligns with two adjacent inlet openings to correspond to
