Such a water fitting comprises a fitting body and a water outlet pipe held on the fitting body, by means of which, for example, water is led to a water outlet of the water fitting. The water fitting further has a mounting surface via which the water fitting can be supported on a component to which the water fitting is at least indirectly fastened. The component is, for example, a worktop or a sink with a basin into which the water flowing out of the water fittings can flow.

The water fitting furthermore has at least one mixing region arranged at least partially on one side of the mounting surface, in which hot water flowing through the fitting body can be mixed with cold water flowing through the fitting body. The hot water is warm water, which is heated, for example by means of a heater. The cold water is cold water and has a lower temperature than the hot water. In the mixing area, the hot water can mix with the cold water or vice versa, so that a mixture of the hot water and the cold water are set can. Usually, the mixing area is arranged in the fitting body and thereby at least partially, in particular at least predominantly or completely, arranged on the said side of the mounting surface. Based on a state in which the water fitting is arranged on said component, the mixing region is thus at least partially, in particular at least predominantly or completely, arranged under the component.

Object of the present invention is to develop a water valve of the type mentioned in such a way that a particularly advantageous functionality of the water fitting can be realized.

This object is achieved by a water fitting with the features of claim 1. Advantageous embodiments with expedient developments of the invention are specified in the remaining claims.

The invention relates to a water fitting, in particular for a caravan, caravan, Motorcaravan, or a boat. The water fitting comprises a fitting body and a water outlet pipe held on the fitting body. Furthermore, the water fitting has a mounting surface, via which the water fitting can be supported on a component to which the water fitting is at least indirectly fastened. The water fitting furthermore has at least one mixing region arranged at least partially on one side of the mounting surface for mixing cold water flowing through the fitting body through hot water flowing through the fitting body.

In order to be able to realize a particularly advantageous functionality of the water fitting, it is inventively provided that on one side opposite the second side of the mounting surface at least one circumferential in the circumferential direction of the fitting body at least partially encircling and formed by at least a first housing part and a second housing part of the fitting body annular channel is arranged, via which the water outlet pipe with water from the mixing region can be supplied, wherein the water outlet pipe is held on the second housing part and is rotatable together with the second housing part about an axis of rotation relative to the first housing part.

In other words, the water fitting is based on the idea of arranging the mixing region at least partially, in particular at least predominantly or even completely, upstream of the mounting surface with respect to the direction of flow of the water, with the annular channel downstream of the mounting surface and thus the possibility of connecting the water outlet pipe together to be rotated with the second housing part relative to the first housing part, are arranged. As a result, a particularly compact construction of the water fitting can be created. In addition, it is possible to rotate the second housing part and with this the water outlet pipe relative to the first housing part. As a result, the water fitting according to the invention can also be installed in particularly narrow spaces.

Preferably, the annular channel runs completely in the circumferential direction of the fitting body, whereby a supply of the water outlet pipe can be ensured in at least almost every rotational position.

In order to realize a particularly advantageous functionality of the water fitting, it is provided in another embodiment that the water outlet pipe is rotatable together with the second housing part by at least 360 ° °, in particular by a multiple of 360 °, about the axis of rotation relative to the first housing part ,

Preferably, it is provided that the rotation of the water outlet pipe and the second housing part relative to the first housing part is unlimited or limitless, so that the second housing part and thus the water outlet pipe are rotatable by a multiple by 360 ° relative to the first housing part.

In an advantageous embodiment of the invention, the water outlet pipe is pivotable about a pivot axis extending obliquely or perpendicular to the axis of rotation relative to the housing parts. As a result, for example, the height of a water outlet of the water fitting can be adjusted, so that the height of the water outlet can be adapted to different sized items such as pots. The water outlet comprises at least one outlet opening, over which the water fitting flowing through water can flow out of the water fitting. Furthermore, a particularly low space requirement of the water fitting can be realized by the pivotability of the water outlet pipe about the pivot axis.

In order to keep the number of parts and thus the space requirement of the water fitting particularly low, it is provided in a further embodiment of the invention that the annular channel is limited in its radial direction inwardly through the first housing part and in the radial direction outwardly through the second housing part.

A further embodiment is characterized in that the second housing part surrounds the first housing part completely circumferentially in its circumferential direction, thereby the number of parts and thus the cost and space requirement of the water fitting can be kept particularly low. At the same time a supply of the water outlet pipe can be ensured with the water from the mixing area in at least almost every rotational position of the second housing part and thus the water outlet pipe.

In a particularly advantageous embodiment of the invention, the annular channel is sealed by means of two opposing and on the housing parts each supported sealing elements. As a result, the annular channel can be sealed particularly effectively and efficiently, wherein the number of parts and thus the weight, the cost and the space requirement of the water fitting can be kept particularly low.

It has proven to be particularly advantageous if the fitting body along its longitudinal direction on the second side has a height of a maximum of 50 millimeters, in particular a maximum of 40 millimeters. As a result, the height of the fitting body and thus the water fitting can be kept very low overall.

Finally, it has proven to be advantageous if arranged on the first side at least one fastening element, by means of which the water fitting to the Component is fastened. This allows a particularly space-saving attachment to the device can be realized.

Fig. 1 shows in a schematic front view of a generally designated 10 water fitting, in particular for a caravan, caravan, Motorcaravan, or a boat. The water fitting 10 comprises a fitting body 12 and a valve body 12 held on the water outlet pipe 14, which has a water outlet 16 of the water fitting 10 has. Via the water outlet 16, water flowing through the water fitting 10 can flow out of the water fitting 10.

Out Fig. 1 to 4 is a detail of a component 18 of the caravan, caravan, motor caravan or boat recognizable, the water fitting 10 is attached to the device 18. For this purpose, the water fitting 10 - as very good Fig. 3 and 4 is recognizable - a mounting surface 20, which is formed by a first housing part 22 of the water fitting. For example, the first housing part 22 is formed from a plastic. Alternatively or additionally, it is conceivable that the first housing part 22 is integrally formed. About the mounting surface 20, the water fitting 10 is supported in its attached to the device 18 state on the device 18. The component 18 is, for example, a worktop or a sink with a basin into which the water flowing out of the water fitting 10 via the water outlet 16 can flow.

The water fitting 10 also has a Fig. 3 and 4 recognizable mixing area 24. The mixing region 24 is arranged at least partially and in the present case at least predominantly on a first side 26 of the mounting surface 20. The water fitting 10, in particular the fitting body 12, has Fig. 4 recognizable and can be traversed by the water channels 28 and 30, wherein the first channel 28, for example, hot water or warm water and the second channel 30 of cold water or cold water can be flowed through. The hot water is heated by means of a heater and therefore has a higher temperature than the cold water. The mixing area 24 serves to mix the hot water with the cold water. In other words, the mixing region 24 is fluidically connectable to the channels 28 and 30, so that the hot water and the cold water can be supplied to the mixing region 24.

The water fitting 10 comprises a valve element 32, which is presently designed as a cartridge or mixing cartridge. By means of the valve element 32 (cartridge) is a mixture of the hot water and the cold water adjustable. In other words, the respective fluidic connection of the mixing region 24 with the channels 28 and 30 is adjustable by means of the valve element 32, so that by means of the valve element 32, the ratio of hot water to cold water can be adjusted. This is the Valve element 32, for example, relative to the fitting body 12 movable, in particular rotatable.

The water fitting 10 comprises an operating element in the form of an operating lever 34, which is at least partially disposed outside of the fitting body 12 and held movably on the fitting body 12. Further, the operating lever 34 is coupled to the valve element 32, so that the valve element 32 is movable via the operating lever 34 by a person by the person moves the operating lever 34 relative to the valve body 12. This allows the person via the control lever 34 adjust the ratio of hot water to cold water. Alternatively or additionally, it is conceivable that by means of the control lever 34, a water outlet 16 flowing through the amount of water is adjustable.

The water outlet 16, the water from the mixing region 24 can be fed, wherein the water outlet 16 is disposed downstream of the mixing region 24 based on the flow direction of the water through the water fitting 10. In this case, the water outlet pipe 14, for example, one of the water from the mixing region 24 can be flowed through channel 39, via which the water from the mixing region 24 to the water outlet 16 can be fed. For example, the channel 39 of the water outlet pipe 14 is fluidly connected to the mixing area 24 or connectable.

In order to realize a particularly advantageous functionality of the water fitting 10, on one of the first side 26 opposite, second side 36 of the mounting surface 20 in the circumferential direction of the fitting body 12 completely encircling and limited by the housing part 22 and a second housing part 38 of the fitting body 12 annular channel Arranged 40, via which the water outlet pipe 14 and its channel 39 is supplied with water from the mixing region 24. Out Fig. 3 It can be seen particularly clearly that the channel 39 of the water outlet pipe 14 is fluidically connected to the annular channel 40, so that the water can flow out of the annular channel 40 and into the channel 39.

The separately formed from the second housing part 38 water outlet pipe 14 is at least indirectly and in the present case held at the mediation of at least one further component 42 of the water fitting 10 to the second housing part 38 or connected to the second housing part 38 so that the water outlet pipe 14 together with the second housing part 38 to a in Fig. 1 shown rotational axis 44 is rotatable relative to the first housing part 22 by at least 360 °. In the present case, this rotation of the water outlet pipe 14 and the second housing part 38 relative to the first housing part 22 unlimited or limitless, so that the water outlet pipe 14 and the second housing part 38 can be rotated by a multiple of 360 ° relative to the first housing part 22 about the axis of rotation 44. Since the annular channel 40 completely circumferentially, that extends through 360 ° in the circumferential direction of the fitting body 12, the channel 39 is fluidly connected to the annular channel 40 in each rotational position of the water outlet pipe 14 and the second housing part 38, so that in each rotational position of the channel 39 and Thus, the water outlet 16 can be supplied with water from the mixing area 24.

The rotatability of the water outlet pipe 14 and the second housing part 38 relative to the first housing part 22 is in FIGS. 5 and 6 illustrated by arrows 47. The axis of rotation 44 coincides with the longitudinal direction of the fitting body 12. In addition, one is out Fig. 1 and 2 recognizable pivot axis 46 is provided which is perpendicular to the axis of rotation 44. In this case, the water outlet pipe 14 is pivotable about the pivot axis 46 relative to the housing parts 22 and 38, wherein this pivotability in Fig. 2 is illustrated by arrows 48. Out Fig. 3 is particularly clear that the annular channel 40 is limited in its radial direction outwardly by the outer second housing part 38 and in the radial direction inwardly through the first housing part 22. In this case, the annular channel 40 surrounds the first housing part 22 completely circumferentially in its circumferential direction, wherein the circumferential direction extends around the axis of rotation 44. In particular, the annular channel 40 is formed, for example, rotationally symmetrical to the axis of rotation 44.

Furthermore, two opposite and supported on the housing parts 22 and 38 sealing elements in the form of sealing rings 50 and 52 are provided, by means of which the annular channel 40 is sealed. The sealing rings 50 and 52 are supported on the housing parts 22 and 38, so that the housing parts 22 and 38 are sealed by means of the sealing rings 50 against each other.

In order to keep the space requirement, in particular the height along the axis of rotation 44, of the water fitting 10 to be particularly small, the fitting body 12 preferably has a height of at most 40 millimeters along its longitudinal axis of extension coinciding with the axis of rotation 44 on the second side 36.

In addition, on the first side 26 at least one fastening element in the form of a thread 54 is arranged, which is designed as an external thread. By means of this external thread, the water fitting 10 is fastened or attachable in total to the component 18. For this purpose, another fastener in the form of a nut 56 is used, which has a corresponding with the external thread internal thread. The nut 56 is screwed on its internal thread on the external thread (thread 54), so that the device 18 between the mounting surface 20 and the nut 56 is clamped. As a result, the water fitting 10 is fastened to the component 18.

As in Fig. 5 is illustrated by an arrow 58, the operating lever 34 can be pivoted relative to the housing parts 22 and 38, thereby adjusting, for example, the above-described ratio of hot water to cold water. In this case, the water fitting 10 includes, for example, a cover 60, which is mitverschwenkbar with the operating lever 34. For example, the operating lever 34 and the cover 60 are pivotable about a pivot axis relative to the housing parts 22 and 38, wherein this pivot axis coincides with the axis of rotation 44.
