Sanitary shower head with a pulsator disc

Description

[0001] The present invention relates to a sanitary shower head for a sanitary fitting. Sanitary fittings serve in particular to provide liquids, such as water, as needed at a sink, a washbasin, a shower or a bathtub.

[0002] Shower heads for bathroom fixtures can be designed, for example, as overhead or hand showers and / or serve to distribute the liquid dispensed by the fixture over a large area. The liquid can be dispensed from the shower head in at least one spray pattern, such as rain jets, solid jets, or aerated jets. However, a disadvantage of shower heads is that the spray patterns are weak at low liquid pressure.

[0003] The object of the invention is therefore to at least partially solve the problems described with reference to the prior art and in particular to provide a sanitary shower head through which the jets can be fully developed even at a low liquid pressure.

[0004] This problem is solved by a sanitary shower head according to the features of the independent claim. Further advantageous embodiments of the invention are specified in the dependent claims. It should be noted that the features listed individually in the dependent claims can be combined with one another in any technologically meaningful way and define further embodiments of the invention. Furthermore, the features specified in the claims are further specified and explained in the description, which also presents further preferred embodiments of the invention.

[0005] A sanitary shower according to claim 1 contributes to this.

[0006] The shower head is particularly suitable for use with sanitary fittings. Sanitary fittings serve primarily to provide liquids, especially water, on demand at sinks, washbasins, showers, and / or bathtubs. For this purpose, the sanitary fittings can be supplied with cold water at a specific temperature and hot water at a specific temperature, which can be mixed by the sanitary fittings, for example, by means of a mixing valve or a thermostatic mixing cartridge, to create a mixture with the desired temperature. The cold water temperature is preferably a maximum of 25 °C, more preferably 1 °C to 25 °C, and more preferably 5 °C to 20 °C, and / or the hot water temperature is preferably a maximum of 90 °C, more preferably 25 °C to 90 °C, and more preferably 55 °C to 65 °C.The mixed water can then be supplied to the shower head, for example via a liquid line or hose. The shower head can be designed as a shower head or hand shower. It can be permanently attached to a support, such as a wall, or it can be moved by the user. The shower head allows the liquid, e.g., water, to be sprayed, particularly in at least one spray pattern.

[0007] For this purpose, the sanitary shower head has a housing with at least one supply channel. The housing can be made at least partially of metal and / or plastic.

[0008] The liquid can be supplied to the shower head via at least one supply channel. For this purpose, at least one supply channel can be connected to the liquid line or hose of the sanitary fitting. The at least one supply channel opens into a pulsator chamber in the housing. The pulsator chamber is a receiving space in the housing for a pulsator disc.

[0009] To produce at least one spray pattern, the sanitary shower head has a spray pattern generator with a multitude of nozzles for the liquid. The spray pattern generator can be integrated into the housing or be a separate component. In particular, the spray pattern generator can be disc-shaped and / or located on the underside of the housing. The nozzles can be designed, in particular, as openings in the spray pattern generator.

[0010] The liquid outlet nozzles are assigned to a plurality of chambers of the sanitary fitting 1, through which the liquid can be supplied to the outlet nozzles. In particular, each chamber is assigned a plurality of outlet nozzles, for example, two to ten outlet nozzles. Liquid can therefore only be supplied to the outlet nozzles via their respective assigned chamber.

[0011] Each chamber has a chamber inlet through which it is connected to the pulsator chamber. This allows the fluid to flow from the pulsator chamber into the individual chambers via the chamber inlets and thus be directed to the outlet nozzles assigned to each chamber. The chambers are, in particular, cavities within the housing, which may, for example, be located on the rear side of the jet former.

[0012] A pulsator disc is arranged within the pulsator chamber. This disc is movable by the fluid such that at least one of the chamber inlets can be at least partially or completely closed alternately. The movement of the pulsator disc is achieved exclusively by the flow energy of the fluid entering the pulsator chamber. The chamber inlets are connected to the pulsator chamber in a circular fashion and / or are located below a pivot point of the pulsator disc. The pulsator disc is movable by the fluid in such a way that it wobbles or rotates around its pivot point. This causes the individual chamber inlets to be at least partially or completely closed successively by the pulsator disc or a side wall of the pulsator disc, either clockwise or counterclockwise.The pulsator disc ensures that the chambers are alternately and rotationally supplied with liquid, meaning that only a portion of the majority of chambers are ever open or at least partially closed. This allows strong liquid jets to be generated through the outlet nozzles even with low incoming liquid pressure.

[0013] The pulsator disc can be designed in the form of a disc. In particular, the pulsator disc is designed as a circular disc and / or consists at least partially of plastic or metal. Furthermore, the pulsator disc can have a diameter of 10 mm to 60 mm and / or a thickness of 1 mm to 10 mm.

[0014] The pulsator disk is supported at a single point. For this purpose, the pulsator chamber can have a bearing by which the pulsator chamber is supported at a single point. The pulsator disk, particularly at its center, can rest on a tip of the bearing. On the tip of the bearing, the pulsator disk can be tilted in any direction.

[0015] The pulsator disk can be moved in a circular motion around its center point by the fluid.

[0016] The pulsator disc can be held in place by a spring. The spring can press the pulsator disc firmly against the bearing. This prevents disruptive noise from the pulsator disc within the pulsator chamber. The spring can, for example, be a coil spring.

[0017] The chamber inlets can be located in the center of the beam former, with the chambers extending radially outwards from the inlets. This means, in particular, that the chamber inlets are formed in a central region of the beam former within the pulsator chamber. The chambers extend, at least partially, across a surface area of ​​the rear side of the beam former.

[0018] The chambers can be triangular in shape. This can mean, in particular, that the chambers have a (generally) triangular base parallel to the rear side of the beam former. Due to the triangular shape of the chambers, the entire rear side of the beam former can be easily covered by a majority of them.

[0019] The chamber inlets can be alternately, at least partially, closed by the rotational pulsator disc. This can mean, in particular, that adjacent chamber inlets can be closed at least partially one after the other by the pulsator disc.

[0020] The flow of liquid from the outlet nozzles cannot be interrupted, especially when the chamber inlets are at least partially closed. This can mean, in particular, that even when the chamber inlets are at least partially closed, the flow of liquid from the outlet nozzles is not interrupted.

[0021] The diameter of the pulsator disk can be made so small that the pulsator disk rotates at a frequency of at least 0.5 Hz (Hertz) at a fluid pressure of 1 bar.

[0022] The chambers can be separated from each other by at least one chamber boundary. This at least one chamber boundary can be designed like a partition wall that prevents the flow of liquid between individual chambers.

[0023] The invention and its technical context are explained in more detail below with reference to the figures. It should be noted that the figures show a particularly preferred embodiment of the invention, but that the invention is not limited to this embodiment. Identical components in the figures are designated with the same reference numerals. The figures show, by way of example and schematically: Fig. 1: a sanitary shower in a longitudinal section; Fig. 2: the sanitary shower in a perspective detail view; and Fig. 3: the sanitary shower in a top view.

[0024] The Fig. 1 Figure 1 shows a sanitary shower head 1 in longitudinal section. The sanitary shower head 1 can be a hand shower or a shower head. The sanitary shower head 1 comprises a housing 2, which is designed here as a flow-through component. A supply channel 4 for a liquid is formed in the housing 2, which opens into a pulsator chamber 3 of the housing 2. For supplying the liquid, the housing 2 can be connected to a supply line (not shown) via a first thread 15. A pulsator disc 11 is arranged in the pulsator chamber 3, which is point-supported at its center 12 on a bearing 16 and is pressed against the bearing 16 by a spring 13. The housing 2 is connected to a spray pattern 5 via a second thread 17. The jet former 5 has a plurality of outlet nozzles 6, which are assigned to chambers through which the liquid can be supplied to the outlet nozzles 6.Each chamber is assigned a plurality of outlet nozzles 6. The sanitary shower head 1 shown here has a total of ten chambers, of which in the . Fig. 1 However, only a first chamber 7 and a second chamber 8 are visible. The chambers of the sanitary shower 1 extend across all outlet nozzles 6 on a rear side 18 of the spray pattern 5, so that liquid can be supplied to all outlet nozzles 6 via the chambers. For this purpose, the chambers can extend (essentially) across the entire rear side 18 of the spray pattern 5. The first chamber 7 has a first chamber inlet 9, through which the first chamber 7 is connected to the pulsator chamber 3. Correspondingly, the second chamber 8 has a second chamber inlet 10, through which the second chamber 8 is connected to the pulsator chamber 3. The remaining chambers of the sanitary shower 1 are identical in design to the first chamber 7 and second chamber 8. The chamber inlets are annular in a center 14 of the spray pattern 5 and below the pulsator disc 11.During operation of the sanitary fitting 1, the liquid flows tangentially into the pulsator chamber 3 via the supply channel 4 and forms a fluid vortex within the chamber. This causes the pulsator disc 11 to tilt circumferentially due to its point-like mounting on the bearing 16, so that the adjacent chamber inlets are successively, at least partially, closed by the pulsator disc 11. This at least partially prevents the liquid from flowing from the pulsator chamber 3 into the respective chambers.

[0025] The Fig. 2 Figure 1 shows the sanitary shower head 1 in a perspective detail view. Particularly visible is a tangential opening 19 of the supply channel 4 into the pulsator chamber 3, through which a vortex flow can be formed in the pulsator chamber 3.

[0026] The Fig. 3 shows a top view of the sanitary fitting 1 in the direction of the jet former 5. In the Fig. 3Only the first chamber 7 is shown schematically and as an example. The first chamber 7 is triangular in shape and extends radially outwards from its first chamber inlet 9. The remaining chambers (not shown here) are identical in shape and arranged side by side and in a circle around the center 14 of the jet former 5. Each chamber has six outlet nozzles 6, to which liquid can be supplied via the respective chamber. The individual chambers are separated from each other by a chamber boundary 20, similar to partition walls, so that no liquid can flow between the individual chambers.

[0027] The present invention allows the jets formed by the exit nozzles to be fully developed even at low liquid pressure. Reference symbol list
