Description

Sanitary interface, use thereof, modular kit for manufacturing same, and sanitary fitting

Technical Field

The invention relates to a sanitary connection for connecting two liquid-conducting connecting elements, to a sanitary fitting, to a modular kit for producing a sanitary connection, and to the use of a sanitary connection in a water guide of a sanitary fitting.

Background

The sanitary connection of the generic type comprises two fluid-conducting connecting elements which are connected to one another in the use position and form an outwardly sealed fluid line, and the second of which is constructed or arranged at the hose end.

The same type of sanitary interface is previously disclosed in practice in different embodiments.

Disclosure of Invention

The object of the present invention is to provide a sanitary connection of the type mentioned at the outset with improved use characteristics.

In order to solve this problem, a sanitary connection of the type mentioned at the outset is first proposed, which has a first liquid-conducting connecting element and a second liquid-conducting connecting element, which are connected to one another in the use position and form an outwardly sealed liquid line, and which are formed or arranged at the hose end, characterized in that the liquid line is sealed at the connection point between the first connecting element and the second connecting element by an axial seal, and the first connecting element is formed or arranged at the sanitary function. The functional element can be, for example, a water outlet element and/or a jet regulator for a sanitary fitting.

In one embodiment of the sanitary connection, it is provided that the axial seal is designed as a non-releasable axial seal. In order to construct an in particular non-releasable axial seal, the first connecting element and the second connecting element can be connected to one another in a material-locking manner. The material-locking connection for producing the axial seal between the first connecting element and the second connecting element can be produced, for example, by laser welding, ultrasonic welding and/or friction welding.

In order to solve this problem, a sanitary connection of the type mentioned at the outset is also proposed, which has a first liquid-conducting connecting element and a second liquid-conducting connecting element, which are connected to one another in the use position and form an outwardly sealed liquid line, and which are formed or arranged at the hose end, characterized in that the liquid line is sealed at the connection point between the first connecting element and the second connecting element by a releasable axial seal. As releasable axial seal, for example, a releasable axial seal ring can be used.

By using an axial seal to seal the connection between the first connection element and the second connection element, both types of sanitary interfaces can be installed particularly simply.

In addition, the axial seal is characterized by its reliable and load-bearing sealing action.

In one embodiment of the aforementioned sanitary connection, it is provided that one of the two connecting elements is designed as a hose or hose nipple. In a sanitary connection with a connecting element in the form of a hose nipple, the hose and the hose nipple connected to the hose nipple can be composed of the same material and/or be integrally formed or can of course also be made of different materials.

In one embodiment of the sanitary connection, it is provided that at least one of the two connecting elements is embodied as a water outlet or is embodied or arranged on a water outlet. Preferably, at least one of the two connecting elements is configured as a water outlet for a sanitary fitting or is arranged or configured on the water outlet. The water outlet member may be a water outlet member without a hose nipple.

Furthermore, the aforementioned water outlet element can be made of a different material than, for example, the aforementioned hose and/or can be configured, for example, as a hose nipple.

In one embodiment of the sanitary connection, it is provided that the connection direction for connecting the first connection element and the second connection element extends transversely, in particular perpendicularly, to the flow direction of the liquid through the liquid line. The installation of the sanitary connection can be further simplified by the connection direction thus defined. Even in the case of small construction spaces, installation is possible. In order to reach the connection position of the two connecting elements, the paths through which the two connecting elements must pass relative to one another can also be particularly short in this connection direction, which is transverse, in particular perpendicular, to the flow direction of the liquid through the liquid line.

The use of an axial seal for sealing the connection point between the first connecting element and the second connecting element also facilitates the installation of the sanitary connection as simply as possible.

In one embodiment of the sanitary connection, it is provided that at least one of the connection elements has at least one fastening element which can be connected to a mating fastening element of the sanitary fitting which is adapted to the fastening element. In this way, at least one of the two connecting elements can be fastened on or in the sanitary fitting. This embodiment of the sanitary interface is advantageous in particular when the at least one aforementioned connecting element is configured as a water outlet for a sanitary fitting.

A particularly comfortable and also reliable connection of the two connecting elements is possible when the connection between the two connecting elements is configured as an interposed swivel connection. The connection between the two connecting elements can also be constructed as a sliding connection. The sanitary interface may further comprise a latching connection, by means of which the connection between the two connecting elements can be ensured against accidental release.

Each connecting element can have a corresponding part for the insertion and rotation connection. Sealing elements, in particular axial sealing elements, such as axial sealing rings, can be arranged and/or embodied between the connecting elements.

In one embodiment of the sanitary connection, it is provided that the first connecting element can be connected to the second connecting element in at least two different orientations of the two connecting elements relative to one another. In this way, the connection between the two connection elements can be performed in at least two defined angular positions relative to each other. In particular, if one of the two connecting elements is a water outlet piece of a sanitary fitting or is embodied or arranged on the water outlet piece, the water outlet piece can be arranged in the sanitary fitting in at least two different installation positions and can be connected to the second connecting element of the sanitary connection in both installation positions.

In one embodiment of the sanitary connection, it is provided that the first connecting element has a guide mechanism. The guide means can define the connection direction of the two connection elements, for example as already mentioned. The connection direction which is to be followed for establishing the connection between the two connection elements according to the specification can be clearly predefined by the guide means. This would facilitate as simple an installation of the sanitary interface as possible even under narrow installation conditions.

By means of the aforementioned guide means, the orientation of the first connecting element relative to the second connecting element can also be achieved when connecting the first connecting element to the second connecting element. The guiding means of the first connecting element can thus clearly determine the relative position of the second connecting element with respect to the first connecting element. The guide means can thus define at least one well-defined relative position of the two connecting elements with respect to one another, in which a connection between the two connecting elements is established as specified.

In one embodiment of the sanitary connection, it is provided that the first connecting element and/or the second connecting element has a sealing surface which surrounds the liquid line. The sealing surface may be an annular sealing surface. When the circumferential sealing surface is formed on the first connecting element, it can be axially acted upon by the second connecting element in the use position. When the circumferential sealing surface is formed on the second connecting element, it can be axially acted upon by the first connecting element in the use position.

In one embodiment of the sanitary connection, the two connecting elements can be connected to one another in a movement transverse to the flow direction of the liquid by means of a liquid line formed by the connecting elements. In this case, for example, the axial seal already mentioned above can be formed and/or closed between the first connecting element and the second connecting element.

To solve this task, a sanitary fitting having a sanitary interface according to the invention is also proposed.

In order to solve this problem, a modular kit for producing a sanitary connection, in particular a sanitary connection according to the invention, is finally proposed, which is characterized in that the modular kit has at least two water outlet elements for sanitary fittings with sealing surfaces having different angles and/or at least two hose connectors having different angles and/or at least two hoses having hose ends having different angles.

Finally, to solve this task, the use of the sanitary connection according to the invention in a water guide of a sanitary fitting is also proposed. The water guide can be functionally separated from the mechanical fastening of the sanitary function, for example of the water outlet piece and/or of the jet regulator, which sanitary function is to be fastened in or on the sanitary fitting. By using the sanitary interface, the sanitary fitting can be constructed freely and independently of the water guide.

Detailed Description

In the following description of the different embodiments of the invention, elements which are functionally identical are given identical reference numerals, even in the case of different designs or designs.

The entire figure shows at least part of a sanitary interface, indicated as a whole with 1, having a first connection element 2 for guiding a liquid and a second connection element 3 for guiding a liquid. The first connecting element 2 and the second connecting element 3 are connected to each other in the position of use and form an outwardly sealed liquid line. The second connecting element 3 is constructed or arranged on the hose end 4 of the hose 9 according to the embodiment of the sanitary connection 1.

The liquid line formed by the two connecting

elements

2 and 3 is sealed at the connection point 5 between the first connecting element 2 and the second connecting element 3 by an axial seal 6. In all the sanitary interfaces 1 shown in the figures, the first connecting element 2 is constructed or arranged on the sanitary function 7.

In both embodiments of the sanitary connection 1 shown in fig. 17 to 24, the axial seals 6 are each formed as non-releasable axial seals 6. In order to form the non-releasable axial seal 6, the first connecting element 2 and the second connecting element 3 are connected to one another in a material-locking manner. In the sanitary interface 1 embodiment shown in fig. 17 to 19, the first connecting element 2 and the second connecting element 3 are welded to each other, for example by ultrasonic welding. In the embodiment of the sanitary interface 1 shown in fig. 20 to 24, the two connecting

elements

2 and 3 are connected to one another by laser welding. Here, one of the two connecting

elements

2, 3 may provide an opaque surface, while the other of the two connecting

elements

2, 3 provides a transparent surface.

In other embodiments, the connecting

elements

2, 3 are connected by ultrasonic welding.

Fig. 20 to 22 show that laser welding as a method for connecting the two connecting

elements

2 and 3 allows a relatively large degree of freedom in design. In each of the three sanitary interfaces 1 shown in fig. 20 to 22, the second connecting element 3 is fastened to the first connecting element 2 in different angular positions.

In the embodiment of the sanitary connection 1 shown in fig. 1 to 16, the connection points 5 between the first connecting element 2 and the second connecting element 3 are each sealed by a releasable axial seal 6 in the form of an axial sealing ring. In the embodiment of the sanitary connection 1 shown in fig. 1 to 8, the axial seal 6 is a rounded, here circular, axial sealing ring.

In the embodiment of the sanitary connection 1 shown in fig. 9 to 11, a circular axial sealing ring is used as the axial seal 6.

The axial seal 6 of the embodiment of the sanitary interface 1 shown in fig. 12 to 16 is a sealing ring having a shape similar to a rectangle with rounded inner corners and rounded outer corners and may also be referred to as an extended oval shape.

In the embodiment of the sanitary interface 1 shown in fig. 1 to 8 and 12 to 16, the second connecting element 3 has a hose nipple 8. In the embodiment of the sanitary connection 1 shown in fig. 9 to 11, the first connecting element 2 comprises a hose nipple 8 which accommodates the second connecting element 3 embodied on the hose end 4 of the hose 9.

The sanitary connection 1 shown in the remaining figures has a second connecting element 3, which is designed as a hose 9. In a sanitary interface 1 comprising a hose nipple 8 to which a hose 9 is connected, the hose nipple 8 and the hose 9 may be constructed of the same material and/or integrally.

In all the embodiments of the sanitary connection 1 shown in the figures, the first connecting element 2 is designed as a water outlet 10 for a sanitary fitting 11 and thus as a functional element 7. Embodiments of sanitary fittings are shown, for example, in fig. 8, 15, 16, and 19 and 24. The water outlet members 10 are each adapted to receive a jet regulator 17. The jet regulator 17 is also a functional element 7 for the sanitary fitting 11, as is the water outlet element 10.

In a further embodiment, not shown, the connecting element 2 is directly integrally formed on the jet regulator 17, so that the jet regulator forms the water outlet 10.

In another embodiment, which is also not shown, the water outlet 10 has no jet regulator 17.

Fig. 17 to 24 show an embodiment of the water outlet 10 without the hose nipple 8.

In particular, the water outlet piece 10 of the embodiment of the sanitary connection 1 shown in fig. 1 to 16 can be constructed from a different material than the respective hose 9 and/or the respective hose nipple 8.

In particular, in the embodiment of the sanitary connection 1 shown in fig. 9 to 16, the connection direction for connecting the first connecting element 2 and the second connecting element 3 is oriented transversely or perpendicularly to the flow direction of the liquid through the liquid line of the sanitary connection 1. In all sanitary interfaces 1, it is provided that at least one of the two connecting

elements

2, 3, i.e. the respective first connecting element 2, has at least one fastening element 12, which can be connected to a mating fastening element 13 of the sanitary fitting 11, which is adapted to the fastening element, into which the respective first connecting element 2 is inserted.

In the sanitary connection 1 shown in fig. 1 to 8, the connection between the two

connection elements

2 and 3 of the sanitary connection 1 is designed as an interposed swivel connection. The manner of operation of the interposed rotary connection between the two connecting

elements

2 and 3 can be clearly seen by comparing fig. 4 and 5 on the one hand with fig. 6 and 7 on the other hand. Fig. 5 and 7 here comprise enlarged individual component views for explaining the connection between the two connecting

elements

2 and 3.

The sanitary connection 1 shown in fig. 12 to 16 is designed such that the connection of the first connecting element 2 to the second connecting element 3 is possible in at least two different orientations of the two connecting

elements

2 and 3 relative to one another. The connection of the sanitary interface 1 between the two connecting

elements

2 and 3 shown in fig. 12 to 16 can be referred to as a sliding connection, which furthermore comprises a latching connection 14 with corresponding latching elements and mating latching elements.

In the embodiment of the sanitary connection 1 shown in fig. 1 to 8, 9 to 11 and 12 to 16, the second connecting element 3 has a sealing surface 15 surrounding the liquid line. The sealing surface 15 is configured annularly and is axially acted upon by the first connecting element 2 of the sanitary connection 1 in the use position, in particular in order to press the axial seal 6 onto the sealing surface 15 of the second connecting element 3. The embodiment of the sanitary connection 1 shown in fig. 1 to 8, 9 to 11 and 12 to 16 has a guide mechanism 16 which is arranged or formed on the first connecting element 2. The connection direction of the two

connection elements

2 and 3 is defined by the guide mechanism 16. Furthermore, the guide means 16 predetermines the orientation of the first connecting element 2 relative to the second connecting element 3 when connecting the two connecting

elements

2 and 3. The guide means 16 on the connecting element 2 of the sanitary connection 1 shown in fig. 1 to 8 comprise a plug guide which predefines the plug direction of the two connecting

elements

2 and 3 for establishing a connection between the two connecting

elements

2 and 3.

The guide means 16 of the first connecting element 2 of the sanitary interface 1 shown in fig. 9 to 11 and 12 to 16 can be referred to as a sliding guide, since they define and prescribe a sliding movement transverse or perpendicular to the flow direction of the liquid through the liquid line. Furthermore, the two guide means 16 of the sanitary connection 1 shown in fig. 9 to 11 and 12 to 16 have at least one end stop which defines and predefines a defined connection position of the two connecting

elements

2 and 3 to one another.

A similar end stop is also predefined in the guide means 16 of the sanitary connection 1 shown in fig. 1 to 8. Furthermore, the guide mechanism 16 of the sanitary connection 1 shown in fig. 1 to 8 comprises a rotational guide, by means of which the rotational component of the connecting movement is guided when the insertion rotational connection between the two connecting

elements

2 and 3 is established.

Each sanitary interface 1 can be understood as a construction style of a modular kit for manufacturing the sanitary interface 1. The modular kit comprises at least two water outlet elements 10 for the sanitary fitting 11 with sealing surfaces 15 having different angles and/or at least two hose connectors 8 having different angles and/or at least two hoses 9 having hose ends 4 having different angles.

In at least some of the sanitary interfaces shown in the figures, the first connecting element 2 and the second connecting element 3 are connected to each other by a movement transverse to the flow direction of the liquid through the liquid line formed by the connecting

elements

2 and 3. This results in an axial seal 6 being formed or closed between the first connecting element 2 and the second connecting element 3.

The aforementioned sanitary connection 1 is therefore used in the water guide of the sanitary fitting 11. The water guide is functionally separated from the mechanical fastening of the sanitary function 7 (for example the water outlet 10 and the jet regulator 17). In this way, the sanitary fitting 11 can be designed largely freely independently of the requirements of the water guide according to the regulations. The housing 18 of the sanitary fitting 11 (which itself accommodates the sanitary connection 1) can thus be made of wood, for example, since the housing 18 itself does not have to be constructed from a water-resistant material, since the sanitary connection 1 has its own water-conducting components.

The present invention is directed to improvements in the field of sanitary interfaces. For this purpose, a sanitary connection 1 is proposed, in particular, in which the two connecting

elements

2 and 3 form, in the connected state, a liquid line which is sealed at a connection point 5 between the first connecting element 2 and the second connecting element 3 by an axial seal 6.
