Description

The present invention relates to a sanitary fitting, which serves in particular the demand-oriented provision of a mixed water with a desired mixed water temperature. Such sanitary fittings are regularly used in conjunction with sinks and / or sinks in sanitary areas.

There are sanitary fittings are known which have a housing and an outlet, which consist at least partially of brass. As a result, drinking water comes into contact with the brass, so that components of the brass can accumulate in the drinking water. However, this is undesirable from a health point of view. For this reason, sanitary fittings have been proposed that include a hose as a water guide. These hoses can z. B. are connected by a holding cartridge or by plugging on a discharge nipple with the water-bearing housing. Due to this structure, the spouts would thus have to be made comparatively wide, especially if they additionally want to realize a pivoting angle limit for the spout. So z. B. end face at the outlet pins or projections to be mounted, which are guided in a groove mounted in the housing and form the end of a stop. In addition, for an implementation of the swivel angle limiting a provided by an orthogonal to the pivot axis of the spout stud could be provided, the end of which is guided in a radially mounted groove. All these constructions therefore do not allow a slim design of the sanitary fitting. Furthermore, in the case of maintenance, for example, when replacing the hose, many components would have to be dismantled, which makes the maintenance very expensive. Furthermore, these constructions have a plurality of sealing points, which increase the risk of leaks.

The object of the invention is therefore to solve the problems described with reference to the prior art at least partially and in particular to provide a sanitary fitting, which can be made slim, easy to maintain and / or has only a small number of sealing points.

These objects are achieved with a sanitary fitting according to the features of the independent claim. Further advantageous embodiments of the sanitary fitting are given in the dependent formulated claims. It should be noted that the features listed individually in the dependent formulated claims can be combined with each other in any technologically meaningful manner and define further embodiments of the invention. In addition, the features specified in the claims are specified and explained in more detail in the description, wherein further preferred embodiments of the invention are shown.

The sanitary fitting has a housing with an outlet, wherein by means of a hose water through the outlet from a hose connection to a jet former of the outlet can be conducted, wherein the hose can be inserted into an outlet nipple of the hose connection. The outlet nipple has, starting from an opening, a groove in which a seal for sealing the hose is arranged opposite the outlet and the groove is at least partially closed with a arranged on an end face of the outlet nipple closure element.

The sanitary fitting proposed here serves, in particular, for the demand-oriented provision of a mixed water having a desired mixed water temperature. Such sanitary fittings are regularly used in conjunction with sink and / or sink. For this purpose, the sanitary fitting in a housing having a mixing cartridge or a mixing valve, with a cold water with a cold water temperature and a hot water with a hot water temperature to a mixed water with the mixed water temperature are miscible. The mixing cartridge and / or the mixing valve can be actuated in particular by means of at least one lever of the sanitary fitting. The cold water temperature is preferably 0 - 40 ° C (Celsius) and / or the hot water temperature 40 - 80 ° C. The housing is in particular at least partially tubular and fastened to a support, for example a worktop or a washing or sink. Furthermore, the sanitary fitting on an outlet, which is in particular rotatably mounted on the housing. By means of the hose, water can be passed through the outlet from a hose connection to a jet former of the outlet. The hose is in particular a plastic hose. For such hoses in particular plastics, such. As polyethylene (PET), suitable. Such plastics are high strength, food safe and thus particularly suitable for use in sanitary fittings for the tapping of water. The jet former is especially a mousseur.

As a result, the water does not come into contact with the spout, which can not be used for drinking water and cheaper materials for the production of the spout can be used. In particular, the complete sanitary fitting is constructed so that no contact between water and housing or outlet comes about. This ensures that the water is completely decoupled from the brass of the sanitary fitting and the sanitary fitting can thus meet all drinking water regulations. As a further advantage, such a sanitary fitting can be used as an "allergy fitting". In addition, a variant reduction can be achieved because no consideration has to be given to the use of different brass materials.

To connect the hose connection with the jet former, the hose can be inserted into an outlet nipple of the hose connection. The outlet nipple is, in particular, a bore or cylindrical recess of the hose connection whose inner diameter substantially corresponds to an outer diameter of the hose. The outlet nipple may also be at least partially tubular. Of the Hose is preferably plugged into the outlet nipple at least 20 mm (millimeters), more preferably at least 40 mm or most preferably at least 60 mm deep. This ensures that the hose can not be pulled so far out of the outlet nipple by pressure surges of the water and faults of the hose in the outlet, that leaks occur. The outlet nipple has, starting from an opening through which the hose is inserted into the outlet nipple, a groove. The groove extends from the opening of the outlet nipple preferably 5 mm to 20 mm in a longitudinal direction of the outlet nipple. In the groove, a seal for sealing the hose from the outlet nipple is arranged. The seal is in particular at least one O-ring. In addition, the groove is at least partially closed by a arranged on an end face of the outlet nipple closure element. In other words, this means that the closure element at least partially closes the opening of the outlet nipple. The closure member may have a bore through which the tube extends. Furthermore, the closure element is preferably not arranged in the groove. The closure element may be a stop nipple. By at least partially closing the groove by the closure element in particular the release of the seal is prevented from the groove. Due to the proposed embodiment of the sanitary fitting maintenance of the sanitary fitting due to a small number of components can be done with little effort. In addition, the hose connection has only a seal for sealing the hose, whereby a risk of leakage due to only a single sealing point is reduced.

Furthermore, it is advantageous if the closure element is attached to a groove toothing. The groove toothing is arranged in particular on a peripheral surface of the outlet nipple. By the groove toothing, the closure element is rotatably connected to the outlet nipple. For this purpose, the closure element has, in particular, an approximately C-shaped cross-sectional area, on the inner surface of which also at least partially a groove toothing is formed. The groove toothing of the closure element and the groove toothing the outlet nipple engage each other in such a way that the closure element is fixed relative to the outlet nipple against rotation of the outlet nipple. By the groove toothing a freely selectable pivot position of the spout is possible, which is independent of a position of the sanitary fitting. Instead of a serration, another positive connection between the connection nipple and the closure element can be provided, which is suitable for preventing or specifically setting a rotation of the closure element about a longitudinal direction of the outlet nipple.

Furthermore, it is advantageous if the closure element is fixed by the outlet. This means in particular that the closure element is held by the outlet on the front side of the outlet nipple or the opening of the outlet nipple.

It is also advantageous if the closure element is designed in the manner of a lid. This means in particular that the closure element at least partially surrounds a peripheral surface of the outlet nipple.

Moreover, it is advantageous if the closure element has a first stop and a second stop, between which in a first intermediate space a stop of the outlet or one is pivotable. The first stop is designed in particular in the manner of a first cam and the second stop in particular in the manner of a second cam. The first cam and the second cam extend in particular from a head side of the closure element in the longitudinal direction. The first stop and the second stop are oriented in particular in a circumferential direction of the closure element. Between the first stop and the second stop, a first intermediate space is defined, which defines a pivoting area of the outlet. A stop of the outlet or a soldering sleeve of the outlet engages in the intermediate space and is pivotable in this up to the first stop and the second stop. For this purpose, the first gap is preferably formed larger than the stop. By displacing the closure element in the groove toothing can Thus, the pivot angle can be adjusted matched with the orientation of the sanitary fitting.

Furthermore, it is advantageous if between the first stop and the second stop (outside the first gap in addition), a second intermediate space is formed, in which the stopper 15 is fixable. By appropriately aligning the closure element on the groove toothing, for example a rotation through 180 °, the stop 15 can be inserted into the second intermediate space or engage, so that the outlet is fixed and thus has no pivoting angle. The second intermediate space and the stop 15 preferably have a substantially congruent size for this purpose.

Moreover, it is advantageous if the outlet is fastened to the housing by means of a fastening component. The fastening component may in particular be a clamp, a screw and / or a pin. In the case of a (prestressed) clamp, this can in particular engage in an inner groove of the spout. As a result, the spout is secured against withdrawal from the housing.

Furthermore, it is advantageous if the outlet has a stop which serves as a hold-down for the closure element.

Moreover, it is advantageous if the stop extends radially inwards from an inner side of the housing.

The Fig. 1 shows a sanitary fitting 1 with a housing 2 and an outlet 3 in a sectional view. The housing 2 is here attached to a support, not shown, which may be in particular a worktop or a sink or sink. The outlet 3 is fitted onto the housing 2 and fastened with a fastening element 14 designed in the manner of a clamp, which engages in an inner groove 17 of the outlet 3. Thus, with the sanitary fitting 1 drawn water does not come into contact with the spout, the sanitary fitting 1 a hose 4, with the water from a hose connection 5 to a jet former 6 can be conducted. The hose connection 5 has an outlet nipple 7, which is at least partially tubular and which extends in a longitudinal direction 13. The tube 4 is inserted through an opening 8 of the outlet nipple 7 in the outlet nipple 7. Starting from the opening 8, a groove 9 extends in the direction of the longitudinal direction 13 of the outlet nipple 7. In this groove 9, a seal 10 is arranged, which seals the tube 4 with respect to the outlet nipple 7 and in this case is an O-ring , The opening 8 is completely closed in this embodiment by a arranged on an end face 21 of the outlet nipple 7 closure element 11. For this purpose, the tube 4 extends through the closure element 11. The closure element 11 is rotationally symmetrical and formed in the manner and a lid. Furthermore, the closure element 11 is attached to a groove toothing 12 which is formed on a peripheral surface 19 of the outlet nipple 7. As a result, the closure element 11 is rotatably connected to the outlet nipple 7. Furthermore, the outlet 3 has a stop 15 which, starting from an inner side 16 of the outlet 3, extends radially inwards. This prevents loosening of the closure element 11 by positive engagement.

The Fig. 2 shows a second embodiment of the sanitary fitting 1 in a sectional view. The second embodiment differs from that in the Fig. 1 shown first embodiment of the sanitary fitting 1 only in that the closure element 11 is fixed with a snap hook 20 on the outlet nipple 7. Furthermore, the outlet nipple 7 and the closure element 11 no groove teeth 12. The second embodiment of the sanitary fitting 1 thereby has no pivoting angle limit of the outlet 3.

The Fig. 3 shows a hose connection 5 in a perspective view, as this finds in the first and second embodiment of the sanitary fitting 1 use. In particular, the closure element 11, which has a first stop 22 and a second stop 23 on the head side, can be seen here. The first stop 22 is here formed by a first cam 24 and the second stop 23 by a second cam 25. Between the first stop 22 and the second stop 23, a first intermediate space 26 is formed, which defines a pivoting range of the outlet 3, not shown here. The stop 15 of the outlet 3 or a soldering sleeve 27 of the outlet 3 engages in the intermediate space 26 and is pivotable in this up to the first stop 22 and the second stop 23. For this purpose, the first intermediate space 26 is formed larger than the stop 15. The stop 15 is formed here on the soldering sleeve 27 and extends from the soldering sleeve 27 radially inwardly. By displacing the closure element 11 in the groove toothing 12, the pivoting angle can thus be adjusted independently of the orientation of the sanitary fitting 1. Furthermore, the closure element 11 has a second intermediate space 18 between the first stop 22 and the second stop 23. By a corresponding alignment of the closure element 11 on the groove teeth 12, for example a rotation through 180 °, the stop 15 can be inserted into the second intermediate space 18 or engage, so that the outlet 3 is fixed and thus has no pivot angle. The second intermediate space 18 and the stop 15 have for this purpose a substantially congruent size.

By the present invention, a sanitary fitting can be made very slim. Furthermore, the sanitary fitting is easy to maintain and has a small number of sealing points.
