Description

[0027] The invention and the technical environment are explained in more detail below with reference to the figures. It should be noted that the figures show a particularly preferred embodiment variant of the invention, but the invention is not limited thereto. The same reference signs are used for the same components in the figures. In an exemplary and schematic manner

[0028] FIG. 1 shows a longitudinal section of a sanitary shower;

[0029] FIG. 2 shows a detailed perspective view of the sanitary shower; and

[0030] FIG. 3 shows a top view of the sanitary shower.

[0031] FIG. 1 shows a longitudinal section of a sanitary shower 1. The sanitary shower 1 may be a hand shower or a ceiling-mount showerhead for a shower. The sanitary shower 1 comprises a housing 2, which is designed here in the manner of a component the flow is directed against. A feed duct 4 for a liquid is formed in the housing 2, which opens into a pulsator chamber 3 of the housing 2. To feed the liquid, the housing 2 can be connected to a feed line (not shown here) via a first thread 15. A pulsator disk 11 is arranged in the pulsator chamber 3, which pulsator disk is mounted at its center 12 in a point-like manner on a bearing 16 and is pressed against the bearing 16 by a spring 13. A second thread 17 is used to connect the housing 2 to a spray plate 5. The spray plate 5 has a plurality of outlet nozzles 6 assigned to chambers through which the liquid can be fed to the outlet nozzles 6. A plurality of outlet nozzles 6 are assigned to each of the individual chambers. The sanitary shower 1 shown here has a total of ten chambers, of which, however, only a first chamber 7 and a second chamber 8 can be seen in FIG. 1. The chambers of the sanitary shower 1 extend on a rear end 18 of the spray plate 5 across all outlet nozzles 6, such that the chambers can supply liquid to all outlet nozzles 6. For this purpose, the chambers may extend (largely) across the entire rear face 18 of the spray plate 5. The first chamber 7 has a first chamber inlet 9, which is used to connect the first chamber 7 to the pulsator chamber 3. Accordingly, the second chamber 8 has a second chamber inlet 10, which is used to connect the second chamber 8 to the pulsator chamber 3. The remaining chambers of the sanitary shower 1 are formed identically to the first chamber 7 and the second chamber 8. The chamber inlets of the chambers are formed ring-like in a central point 14 of the spray plate 5 and below the pulsator disk 11. During operation of the sanitary fitting 1, the liquid flows tangentially into the pulsator chamber 3 via the feed duct 4 and forms a liquid vortex in the pulsator chamber 3. As a result, the pulsator disk 11 is tilted circumferentially by its point-like bearing on the bearing 16, such that the pulsator disk 11 successively and at least partially closes the adjacent chamber inlets.

[0032] This at least partially prevents the liquid from flowing from the pulsator chamber 3 into the individual chambers.

[0033] FIG. 2 shows a perspective detailed view of the sanitary fitting 1. There, in particular, a tangential opening 19 of the feed duct 4 into the pulsator chamber 3 can be seen, through which a vortex-shaped flow can be formed in the pulsator chamber 3.

[0034] FIG. 3 shows a top view onto the sanitary fitting 1 viewed in the direction of the spray plate 5. In FIG. 3, only the first chamber 7 is shown in a schematic manner and by way of example. The first chamber 7 is triangular in shape and extends radially outwards from its first chamber inlet 9. The other chambers (not shown here) are of identical design and are arranged next to each other and in a circle around the central point 14 of the spray plate 5. Six outlet nozzles 6 are assigned to each of the individual chambers, to which outlet nozzles the relevant chamber can conjointly supply liquid . The individual chambers are separated from each other by a chamber partition 20 in the manner of partition walls, such that no liquid can flow between the individual chambers.

[0035] This invention permits the jets formed by the exit nozzles to be fully formed even at a weak fluid pressure.
