Description

Shower head for spray sanitary ware

technical field

The present invention relates to sanitary ware.

Background technique

Shower heads are known in the form of permanently installed shower heads, side showers or hand showers on hose ends. There are various jets which are emitted by such shower heads. Also known are pulsating jets, air-containing jets and jets whose water volume can be varied relatively slowly.

Contents of the invention

The object of the present invention is to provide a shower head which has an attractive appearance and produces a pleasing spray pattern.

In order to achieve this task, the invention proposes a shower head with a housing, a jet disc, at least one jet outlet and a turbine, wherein the jet outlet is formed and arranged in a nozzle that can rotate relative to the jet disc In a member, the turbine is designed to continuously change the direction of the axis of the jet outlet with respect to the housing, characterized in that the nozzle member is embedded in a plate movable by the turbine in the region of its rear end , the plate is driven to rotate about a fixed axis.

Although the jet volume and possibly the jet shape were changed in the known showers, now for the first time the direction of the water flow from the shower head is also changed, to be precise continuously. In this way, it is possible to provide a jet in which the water flows over the skin of the shower user, for example along a closed path, while the shower head is stationary. As a result, not only can a larger area of the body be wetted, but also a massage effect is obtained, which is different from that of current massage showers. Because the jet does not stay on the same part, but these parts change.

In a further development of the invention it can be provided that the turbine operates when water flows out of the jet outlet.

It is particularly advantageous if the turbine is actuated by flowing water. Therefore, no additional drive mechanism operating means are required.

In a development of the invention it can be provided that the direction of the jet outlet changes such that it lies at least partially on a cone and in particular on a cone.

According to the invention, it is also possible to move the axis such that it lies on a double cone.

The invention provides that the tip of the cone is located in the region of the jet disk, so that both the space requirement and the appearance of the shower are reduced compared to known showers.

According to the invention it can be provided that the jet disk has a plurality of jet outlets which can be distributed according to any desired pattern.

When there are many jet outlets, according to the invention the turbine can be formed in such a way that it changes the direction of the axis of more than one jet outlet. Of course, it is also possible to change the direction of some jet outlets while other jet outlets always emit jets in the same direction.

It can be provided according to the invention that the directions of the axes of several jet outlets are changed synchronously. This makes driving easy as movement can be derived from the only turbo.

It can be provided according to the invention that the direction of the axes of several jet outlets is changed in phase, which leads to an apparently uniform jet pattern.

However, it is also possible for the direction to be changed differently in phase.

According to the invention it can be provided that the movement is designed such that the cone axis about which the jet rotates runs perpendicular to the jet disk.

A conceivable measure is that the entire jet disk can be pivoted in order to change the direction of the jet outlet axis. Since the jet outlet is arranged in a nozzle part which is rotatable relative to the jet disk, the change in direction of the axis can be effected by rotating the nozzle part relative to the jet disk and thus relative to the housing.

In particular, it can be provided in a further development of the invention that the nozzle piece, and in particular the water outflow end of the nozzle piece, is mounted in a bore of the jet disk. Thus, the movement of the nozzle part takes place within the shower head housing. Of course, if desired, the nozzle parts can also protrude beyond the jet disk, so that the movement of the nozzle parts can be seen from the outside.

It is also possible to mount the nozzle part on the jet disk by means of elastic means which allow a pivoting movement of the nozzle part.

It can be provided according to the invention that all nozzle parts are embedded in the same plate, so that the plate is moved eccentrically, for example in a circular motion, but does not itself rotate.

In particular, however, each nozzle element engages in a respective plate which is driven to rotate about an axis which is fixed relative to the shower head.

Detailed ways

Figure 1 shows a partial section of a shower head. A jet disk 1 has a slightly convex outer surface 2 on which a number of holes 3 are visible. Formed on the opposite rear side 4 of the jet disk 1 is a cylindrical projection 5 which has an external thread 6 for screwing into the shower head housing. The construction of the extension 5 is covered to the rear by a cover plate 7 which has a shaft 8 protruding into the extension 5 in its center. On the radially outer side of the structure, an opening 9 is formed at a point through which water flowing into the shower head can flow into the extension 5 from the outside to the inside.

A turbine 10 with a sleeve 11 is supported on the shaft 8 . The sleeve 11 is made in the shape of a gear, see also FIG. 4 . The sleeve 11 engages radially at a distance into a central opening 12 of a disk 13 which is mounted in a stationary manner in the extension 5 of the jet disk 1 . The disk 13 has four holes 14 in which the support projections 15 of the plate 16 are supported. The plate 16 is rotatable relative to the disc 13 by means of the bearing lugs 15 . In the region of its outer circumference, the plate 16 has teeth 17 which mesh with the toothed sleeve 11 .

Thus, when the turbine 10 rotates, the plate 16 is caused to rotate.

Each plate 16 has an opening 18 which follows a circular ring as the plate 16 turns.

In the example shown, a total of four nozzle elements 19 are arranged between the plate 16 and the inner surface of the jet disk 1 . Each nozzle piece 19 engages with its rounded front side 20 into a funnel-shaped notch 21 which is arranged behind the bore 3 . In the region of the bore 3 , the thickness of the jet disk 1 is selected such that the nozzle part 19 cannot slide out of the funnel-shaped recess 21 .

At its end facing away from the front side 20 , the nozzle part 19 has a bearing shank 22 which is inserted into the bore 18 of the plate 16 .

The bearing projections of the plate 16 are seated in the axial extension of the midpoint of the bore 3 of the jet disk 1 . Therefore, when the plate 16 is rotated, the nozzle elements are caused to rotate in a rocking motion around the connecting line between the support projection 15 and the midpoint of the hole 3 .

The nozzle part 19 has an axially extending opening 23, the front side of which forms the jet outlet. At about half of the longitudinal extent of the nozzle part 19 , the nozzle part is open on the side, see FIG. 3 , so that that part of the nozzle part 19 facing the turbine 10 has the shape of the yoke 24 . Water from the shower head can flow into the nozzle part 19 from both open sides and exit through the front end. Thus, the axis of the opening 23 constitutes the axis along which the flow of water emerges.

FIG. 5 shows a disk 13 , which is itself in the shape of a wheel, which is fixedly accommodated in the housing. A ring 26 is formed around the central hole 12, from which ring four spokes 27 extend outwards. Furthermore, a ring 28 is provided which has a recess 29 at one point. The function of the notch 29 is to secure the disk 13 in the housing in the correct position.

Approximately in the radial center, holes 14 are provided in the spokes 27 , which constitute bearing holes for the plate 16 .

If water flows into the interior of the extension 5 through the opening 9 , the water first drives the turbine 10 . At the same time, the water flows through the gaps 30 between the spokes 27 of the disc to the nozzle element 19 and from there through its openings 23 to the outside. Rotation of the turbine 10 causes the plate 16 to rotate about a positionally fixed axis. Rotation of the plate 16 causes the above-mentioned rocking movement of the nozzle member 19 . This means that the flow of water emerging from the shower head varies continuously, precisely, in the example shown, along a cone whose apex lies approximately within the jet disk 1 . All nozzle elements 19 move at the same speed.
