Description

Sprinkler

technical field

The invention relates to a showerhead having a housing, a water inlet and a jet outlet surface from which water is expelled through a jet outlet element.

Background technique

A showerhead is known in which a turbine is arranged which causes a periodic movement of the jet outlet body relative to the showerhead housing (EP676241). A speed reducer can be arranged between the turbine and the jet outlet body.

In another known spray device, the jet outlet disk moves eccentrically, but does not rotate. In this, the jet outlet elements made of elastic material as sleeves are moved on the cone, wherein all the jet outlet elements are kept parallel to one another (WO 00/10720).

Massage showers are also known, in which the jet outlet openings are opened and closed in rapid succession. In this case, a pulsating jet should be provided, which should produce a massaging effect when it hits the skin.

Contents of the invention

The object underlying the present invention is to provide a shower head which is to generate a moving jet pattern with a clearly identifiable form of motion.

To solve this object, the invention proposes a shower head with the features stated in claim 1 . Developments of the invention are the subject matter of the subclaims.

The showerhead proposed by the invention therefore comprises a showerhead housing in which the water inlet is guided. The shower head is terminated by a jet outlet surface on the side provided for use. In the shower head housing there is at least one jet outlet element which discharges the spray water from the jet outlet surface. The jet outlet element is rotatably mounted in the housing. The jet outlet element is rotated by a drive device driven by flowing water. A reduction gear is arranged between the drive and the jet outlet element, so that the jet outlet element rotates relatively slowly. The jet pattern delivered by the jet outlet element changes in such a way that it can be clearly felt by the user. That is to say, no pulsating jet should be produced, but rather a jet that changes in direction or course, wherein these changes can also be perceived visually by the user.

The at least one jet outlet element is arranged in the showerhead housing in such a way that it is not regarded as a specific functionally identifiable component. In particular, the jet outlet element should not protrude significantly from the showerhead housing, since a visual effect recognizable by the user should only be perceptible with respect to the jet pattern.

In a development of the invention it can be provided that the jet outlet element has at least one channel which is arranged eccentrically and/or obliquely relative to the axis of rotation of the rotatably mounted jet outlet element. In the case of channels that are arranged purely eccentrically with respect to the axis of rotation, but parallel to the axis of rotation, the position of the jet emerging through such a channel changes, but essentially always remains parallel to itself. In the case of an oblique extension, the direction of the jet also changes. In a combination consisting of eccentric and oblique extension, both (position and direction) of the jet are changed.

In a further development of the invention it can be provided that the shower head housing has a plurality of jet outlet elements, wherein preferably all jet outlet elements are driven by a drive. It is also conceivable to arrange a plurality of jet outlet elements, wherein for example one jet outlet element is fixed while the other jet outlet elements are driven.

Thus, just as a plurality of rotatable jet outlet elements can be provided, the shower head according to the invention can also, in a further development, have a plurality of channels in at least one jet outlet element which are eccentrically and/or relative to the axis of rotation. Or arranged obliquely.

In the case of a plurality of channels running obliquely to the axis of rotation in the jet outlet element, it can be provided in a further development that the channels run parallel to one another.

In a further development of the invention it can be provided that, when a plurality of jet outlet elements are present, their axes of rotation run parallel to one another.

However, it is also possible and within the scope of the invention that, in the case of several jet outlet elements, the axes of rotation of at least two jet outlet elements do not run parallel to one another, but enclose an angle not equal to 0° with one another. Small angles can be involved here.

It has already been mentioned that in the case of several jet outlet elements, these are driven jointly. According to a development of the invention, it can now be provided that at least two of the plurality of jet outlet elements are rotationally driven in the same direction.

However, it is also possible for the jet outlet element to be rotationally driven in the opposite direction.

In a development of the invention it can be provided that at least two, preferably all jet outlet elements are driven with the same peripheral speed.

It is also possible for the jet outlet elements to be driven at different peripheral speeds.

It has proven to be particularly useful in the case of several jet outlet elements that all jet outlet elements have the same size and/or design.

As a speed reducer for relatively slow rotation of the jet outlet element, any gearbox capable of fulfilling this function can be used. An embodiment that has proven to be particularly advantageous is that the gear unit has a worm gear. This makes it possible to directly operatively connect the worm of the worm gear to the jet outlet element, for example to engage in a ring gear of the jet outlet element.

Furthermore, it is possible for this worm to be directly connected to a turbine, which is assigned to the drive.

According to the invention it can be provided that the water inlet into the shower head housing is realized laterally, in particular transversely to the axis of rotation of the jet outlet element. It can be provided here that a turbine is arranged in this lateral water inlet. The use of the lateral inlet makes it possible to configure the shower head as a hand shower head as well. The access can thus be achieved by means of a handle in the usual manner. In the case of head showers, however, the lateral openings can also enable a relatively flat design of the shower head housing, wherein the lateral openings can also be used here for fastening the shower head housing.

Detailed ways

FIG. 1 shows a perspective view of a shower head according to the invention. The shower head comprises a shower head housing 1 which, in the exemplary embodiment shown, is designed as a cylinder. Radially to the cylinder axis, an inlet housing 2 is attached to the shower head housing 1 , which has a connection for a water pipe, hose or the like in a free end face 3 . The end face of the shower head housing 1 , which can be seen in FIG. 1 , then forms the jet outlet surface 4 facing the user. Four perforations 5 are arranged in this jet outlet surface 4 , through which a jet outlet element 6 can be seen in each case. Each of the jet outlet elements 6 has a plurality of jet outlet openings 7 , which are only shown schematically here.

FIG. 2 now shows a cross-sectional view of the inlet housing 2 . An annular chamber 8 is formed in the inlet housing 2 , inside which an inner housing 9 is arranged. The water flowing into the inlet housing 2 first reaches the annular chamber 8 . A turbine 10 with individual blades 11 is mounted rotatably in the inner housing 9 . In the illustrated embodiment, three inlet holes 12 are led obliquely from the annular chamber 8 into the interior of the inner housing 9 , so that water flowing from the annular chamber 8 through the inlet holes 12 impinges on the blades 11 and is This puts the turbine 10 in rotation.

The blades 11 of the turbine 10 are formed on a shaft 13 , which extends transversely through the showerhead housing 1 and is mounted at its opposite end 14 in the showerhead. This can be seen in the cross-sectional view of Figure 3, to which reference is now made. The shaft 13 is the worm of the worm gear. It extends through the cavity 15 in the showerhead. As already mentioned, a plurality of jet outlet elements 6 are arranged in the shower head, to be precise rotatable. The type of support is explained below. On its end pointing toward the interior of the shower head housing 1 , the jet outlet element has a ring gear 16 which meshes with the worm of the shaft 13 . The water driving the turbine 10 passes through the bottom of the inner housing 9 to the interior of the showerhead housing 1 and from there to the exterior through the opening 7 of the jet outlet element 6 . It can already be seen from FIG. 3 that the opening runs obliquely through the jet outlet element 6 . By meshing the ring gear 16 into the worm of the shaft 13 , both jet outlet elements shown below the worm in FIG. 3 turn in the same direction, as does the jet outlet element 6 shown above the worm. However, the upper jet outlet element rotates in the opposite direction of rotation to the lower jet outlet element 6 . The shaft 13 is mounted not only at its end 14 facing away from the rotor 10 but also in a front bearing 17 between the rotor and the worm section.

See Figure 4 now. The shower head housing has a jet base 18 which forms the jet outlet surface 4 and which is relatively thick. This jet base 18 contains, for each jet outlet element 6 , a cylindrical bearing bore 19 for rotatably mounting the jet outlet element 6 . On the inner surface 20 of the jet base 18 is placed an upper part 21 which leaves a water-conducting cavity 22 but restricts or prevents the upward movement of the jet outlet element 6 . The jet outlet element 6 is thus mounted rotatably but axially immovably in the housing.

The jet outlet element is also relatively thick, wherein the ring gear 16 is arranged on the inwardly directed end of the jet outlet element and forms a free space 23 inside the ring gear. This free space 23 serves to guide the water. The opening 7 through which the water emerges is the opening of a channel 24 which is formed in a straight line and thus gives the water a defined direction. As can be seen from FIG. 4 , in the embodiment shown here the channels run not only eccentrically but also obliquely relative to the axis of rotation of the jet outlet element 6 .

FIG. 5 shows an embodiment in which five jet outlet elements are mounted in the fluidic base 18 in a similar manner as in the embodiment according to FIGS. 3 and 4 . The shaft 13 connected to the rotor 10 is designed here to be slightly shorter and also has a slightly shorter worm section 25 . The shaft 13 is supported at 17 directly when entering the shower head housing 1 . The worm section 25 of the shaft 13 is only in mesh with the ring gear 16 of the first jet outlet element 6 . The rotor 10 thus initially only drives the ring gear 16 of the first jet outlet element 6 via the worm 25 . This ring gear 16 meshes with an intermediate gear 26 which then meshes into the ring gear 16 of the next jet outlet element 6 . This continues for all jet outlet elements 6 . Due to the arrangement of the intermediate gear 26, all jet outlet elements 6 rotate in the same direction of rotation.

If the intermediate gear 26 is omitted, an arrangement as shown in FIG. 6 is obtained. Also here the worm 25 of the shaft 13 connected to the rotor 10 meshes only with the ring gear 16 of the first jet outlet element 6 . This ring gear 16 then meshes directly into the ring gear 16 of the adjacent jet outlet element 6 , which again continues for all jet outlet elements 6 . In the embodiment shown in FIG. 6 , adjacent jet outlet elements 6 are therefore each rotated in opposite directions of rotation.

Of course, it is also possible to combine these arrangements, ie to combine a jet outlet element directly connected to one another and a jet outlet element with an intermediate gear 26 .

It should be noted in the sectional view of FIG. 4 that the bearing bores 19 for all jet outlet elements 6 here are designed as cylindrical bores with parallel axes. However, it is also possible for the bearing bores not to run parallel to one another, but to enclose an angle not equal to zero with one another. This is shown schematically in FIG. 7 . The bearing bores 29 for the jet outlet element 6 here enclose an angle, so that the axes of the bearing bores 29 approach each other in the jet direction of the spray. That is, the bearing holes are arranged converging in the direction of the jet. This can be easily achieved when driven by a worm, as can likewise be seen from FIG. 7 . However, this arrangement is also possible with a gear drive.

The shower head housing contains a plurality of jet outlet elements each having a plurality of obliquely running channels forming jet openings. The jet outlet element is rotatably mounted in the housing and the water-driven rotor is brought into slow rotation by means of a gear reducer. Due to the oblique extension of the channel, the jet emerging from the shower head thus performs a defined movement that is visually recognizable to a user of the shower system. The jet outlet elements can all be rotationally driven in the same direction or alternately in different directions.
