Description

The invention relates to a sanitary tub, with at least one Whirlpooldüse with a in an assembly opening of the tub wall (side wall and bottom wall) recorded at least one supply channel for water and / or air nozzle housing.

In the IT RE2004 0055 A1 For a tub, a nozzle is suggested which can be displaced by the water pressure against the action of a spring into the nozzle housing to open the nozzle. Sanitary tubs of this type have the disadvantage that undesired bathing water can penetrate into the Whirlpooldüse and the subsequent pipes and / or are limited in their beam angle for the Einstrahlmedium (water and / or air).

Object of the present invention is to provide a sanitary tub of the type mentioned, in which the penetration of bathing water avoided in the Whirlpooldüse, a larger Ausstrahlwinkelbereich achieved and the direction of Einstrahlmediums of the user can be easily changed.

For this purpose, the sanitary tub according to the invention has received a nozzle body in the nozzle housing, the inner (ie in the tub interior facing) face in a closed position of the nozzle body with the end face of the inner edge of the nozzle housing and the patch on the inner edge of sight ring is aligned, and which from the closed position substantially perpendicular to the inner wall surface of the tub wall in the direction of the tub interior at least partially from the nozzle housing out to an operating position is displaced, in which at least one Ausstrahlkanal the Whirlpooldüse for a Einstrahlmedium (water and / or air) is released.

An advantage of such a sanitary tub is that when the spa system is not in use, no bathing water can penetrate into the whirlpool spout and into the subsequent piping. Since the Whirlpooldüse does not protrude appreciably in the tub interior, it does not bother when not using the whirlpool system. When using the projecting nozzle body (pop-up nozzle), the jet outlet opening of the Ausstrahlkanals can be relatively far in the tub interior, resulting in additional massage options. In this case, the massage jet of the jet medium may exit in all possible angular positions and even parallel to the inner wall surface of the well wall, so that the user of the whirlpool system will not be struck perpendicularly by the massage jet, which may be unpleasant when hitting veins or lymphatic vessels. Due to the flat design of the Whirlpooldüse the sanitary tub also has a better look / design. In pop-up nozzles of the type according to the invention, the user can easily adjust the direction of radiation of the Whirlpooldüse by hand, since the projecting nozzle body can be grasped by hand. The pop-up nozzles are preferably mounted in the side wall of a sanitary tub according to the invention (in any number).

Advantageously, the nozzle body is displaceable against the action of a closing spring from a closed position in the direction of its operating position. In this way, only forces for moving the nozzle body into the operating position are required to operate the whirlpool system, while the closing of the Whirlpooldüse takes place automatically.

Particularly preferably, the nozzle body from its closed position in the direction of its operating position by means of the Einstrahlmediums (water and / or air) itself displaced. This has the advantage that the Whirlpooldüse automatically opens only at the beginning of the whirlpool operation and at the end of the whirlpool operation due to the action of the closing spring immediately inevitably closes and so no bath water can penetrate into the nozzle interior. But it is also possible to move the nozzle body by means of a separate drive (electric motor, hydraulic motor, air motor, etc.) independently or additionally in the various positions.

A simple operation of the nozzle body in the "pop-up nozzle" is given when the at least one supply channel opens into the interior of the nozzle body and this has the least one Ausstrahlkanal.

Furthermore, it may be appropriate to increase the number of different operating options, the supply channel for air and the supply channel for water separately into the nozzle housing and possibly also open into the nozzle body, with the Einstrahlmedien water and air only mix there. This is z. B. possible to use forced air and / or Venturiluft, even with pulsating air supply, wherein the plurality of Whirlpooldüsen individually and / or in groups, e.g. via a program, can be controlled.

According to the invention, there is also the possibility that the at least one outflow channel opens into the tub interior in a vertical, oblique or parallel manner to the inner wall surface of the tub wall.

If several Ausstrahlkanäle are provided, they can open in the same direction or in different directions in the tub interior to achieve a pleasant massage effect.

In a further development of the inventive concept, it is also possible that an inner (ie, a tub interior facing) of the nozzle body is rotatable relative to an outer part of the nozzle body about the longitudinal axis of the nozzle housing, so that during operation of the massage jet or the massage jets, for example Type of rotatable garden sprinkler, revolving.

It may be expedient to arrange the inlet opening of the at least one Ausstrahlkanals eccentric in the nozzle body to promote the rotational movement of the inner part of the nozzle body. Tangential, distributed over the circumference of the inner part of the nozzle body (for example offset by 120 °) can then be connected to the eccentric inlet opening, so that the inner part of the nozzle body is well set into rotation due to the recoil effect.

It is also possible to integrate into the nozzle housing a light source to create special lighting effects.

Other objects, features, advantages and applications will become apparent from the following description of exemplary embodiments with reference to the drawing.

an embodiment of the Whirlpooldüse invention with an (additional) drive for the axial displacement of the nozzle body,

In the in the FIGS. 1 A and 1b illustrated embodiment of a specific for a sanitary tub according to the invention Whirlpooldüse D, which is inserted into a mounting opening 17 of the tub wall 1, has a nozzle housing 2, in which a supply channel 5 for air and a supply channel 6 open for water separately. The nozzle housing 2 has an inner support flange 18 for abutment against the inner wall surface 16 of the tub wall 1 to allow a clamping of the nozzle housing 2 by means of a fastening nut 3 on the external thread 19 of the nozzle housing 2. The support flange 18 of the nozzle housing 2 is covered for aesthetic reasons by a sighting ring 9, which is screwed into the inner end of the nozzle housing 2 substantially. The nozzle housing 2 protrudes only slightly with its inner edge 15 or with the mounted on the inner edge 15 sight ring in the tub interior W inside.

In the nozzle housing 2, a two-part nozzle body 7, 8 is added. The inner end face 20 of the nozzle body 7, 8 is aligned in the in Fig. 1a shown closed position of the nozzle body 7, 8 with the inner end face 21 of the sight ring 9, so that no bathing water can penetrate into the nozzle housing and the whirlpool nozzle due to their training and arrangement little disturbing.

As shown in Fig. 1b is the nozzle body 7, 8 from the in Fig. 1 a shown closed position substantially perpendicular to the inner wall surface 16 of the tub wall 1 to an operating position displaceable, in which an outgoing from a hollow cylindrical outer part 7 of the nozzle body 2 with an inlet 11 oblique radiating channel 10 of the inner part 8 of the nozzle body 2 for the passage a Einstrahlmediums (water and / or air) is released. By replacing the existing nozzle body 7, 8 or only the inner part 8 by another, the particular direction of radiation can be easily preselected.

At the in Fig. 1 A and 1b illustrated embodiment, the nozzle body 7, 8 against the action of a closing spring 4 by means of one of the Einstrahlmedien (water and / or air) axially displaceable in the operating position. The closing spring 4 is supported, on the one hand, on an end surface of the sighting ring 9 pointing away from the tub interior W and, on the other hand, on an annular bead 22 of the outer part 7 of the nozzle body 7, 8.

At the in Fig. 4 illustrated embodiment of the Whirlpooldüse D is an (additional) drive 13 for the axial adjustment of the nozzle body 7, 8 shown in the nozzle housing 2. The drive 13 could also be provided in the nozzle housing 2 itself or the nozzle body 7, 8.

Like from the FIGS. 1a and 1b It can also be seen that the supply channels for air 5 or water 6 both open not only into the nozzle housing 2, but also into the outer part 7 of the nozzle body, so that in this way the displacement of the nozzle body 7, 8 upon activation of one of the Einstrahlmedien effectively in the in Fig. 1b shown operating position (open position) is transferred.

According to the in Fig. 2b illustrated embodiment, the injection port 11 is compared to the embodiment in Fig. 2a eccentrically to the nozzle housing 2, so that the inner part 8 of the nozzle body 7, 8 due to the Ausstrahlmediums, which relative to the outer part 7 of the nozzle body 7, 8 rotatable is stored, can be set in rotation.

In the in the FIGS. 3a and 3b illustrated embodiment of a Whirlpooldüse D branches from the inlet opening 11 more over the circumference of the inner part 8 of the nozzle body 7, 8 offset by 120 ° arranged tangential Ausstrahlkanäle 12, so that the inner part 8 of the nozzle body 7, 8 rotates in the manner of a lawn sprinkler ,
