Description

The present invention relates to a sanitary fitting that can be used in particular in connection with sinks and/or washbasins.

Sanitary fittings are used on sinks, sinks, bathtubs and/or showers to provide a liquid, especially water, as needed. For this purpose, sanitary fittings can have a housing with an outlet and an outlet opening for the liquid. The housing of the sanitary fitting can be attached to a support, for example a worktop or a sink or sink. Furthermore, sanitary fittings can have a mixing valve or a mixing cartridge through which cold water and hot water can be mixed to form mixed water with a desired mixed water temperature.

Sanitary fittings are also known with which various liquids, for example mixed water, carbonated liquid, flavored liquid, filtered liquid, cooled liquid and/or hot water, can be dispensed. In order to direct the various liquids from their respective liquid sources to the outlet opening, several liquid lines are required which extend parallel to one another through the fitting housing and/or the outlet. This results in a high space requirement for the liquid lines, which limits the freedom of design of the fitting housings or outlets. In addition, the individual liquids can be dispensed via separate outlet openings of the sanitary fittings or a mousseur of the sanitary fittings so that they do not come into contact with one another before being dispensed or cannot mix with one another. With a high number of liquids that can be dispensed, a correspondingly high number of outlet openings must be provided or a mousseur must have a correspondingly high number of separate liquid channels, which increases the complexity of the sanitary fitting or the mousseur.

The object of the invention is therefore to at least partially solve the problems described with reference to the prior art and in particular to provide a sanitary fitting through which different or more liquids can be directed to the outlet opening with less space and which has less complexity.

These tasks are solved with a sanitary fitting according to the features of the independent patent claim. Further advantageous embodiments of the sanitary fitting are specified in the dependent patent claims. It should be noted that the features listed individually in the dependent patent claims can be combined with one another in any technologically sensible manner and define further embodiments of the invention. In addition, the features specified in the patent claims are specified and explained in more detail in the description, with further preferred embodiments of the invention being presented.

The tube has at least a first lumen for guiding a first liquid from a first liquid source to the outlet opening, a second lumen for guiding a second liquid from a second liquid source to the outlet opening, and a third lumen for guiding a third liquid from a third liquid source to the outlet opening. In addition, the tube can have at least one further lumen for guiding at least one further liquid from at least one further liquid source. The lumens are in particular each a (tubular) liquid channel which extends through the tube from a first longitudinal end of the tube to a second longitudinal end of the tube. The first longitudinal end of the hose can be connected to the first liquid source, second liquid source and third liquid source (and possibly the at least one further liquid source). Alternatively, the first longitudinal end of the hose can be connected to a distribution device for the at least one first liquid source, second liquid source and third liquid source (and possibly for the at least one further liquid source). The distributor device can be connected to the first liquid source, second liquid source and third liquid source (and possibly the at least one further liquid source). The distributor device can be arranged outside the fitting housing and/or the outlet. The individual lumens run in particular parallel to one another through the tube. The lumens are in particular (together) formed in one piece by the material of the tube. In particular, the lumens are not concentric with one another. The tube can be designed in the manner of a multi-lumen tube or multi-lumen tube and/or not rotationally symmetrical.

The first liquid can be, for example, mixed water and/or the first liquid source can be, for example, a mixing valve or a mixing cartridge. Through the mixing valve or the mixing cartridge, in particular, cold water with a cold water temperature and hot water with a hot water temperature can be mixed to form the mixed water with a desired mixed water temperature. The cold water temperature is in particular a maximum of 25 °C, preferably 1 °C to 25 °C, particularly preferably 5 °C to 20 °C and/or the hot water temperature is in particular a maximum of 90 °C, preferably 25 °C to 90 °C, particularly preferably 55 °C to 65 °C. The mixing valve or the mixing cartridge can be arranged in the fitting housing of the sanitary fitting. The second liquid, the third liquid and/or the at least one further liquid can be, for example, drinking water, mixed water, cold water, hot water, carbonated liquid, flavored liquid, filtered liquid, cooled liquid (for example with a cooling water temperature of 1 ° C up to 10 °C) and/or hot water (for example with a hot water temperature of 90 °C to 100 °C). For example, the second liquid can be hot water and the third liquid can be filtered liquid or filtered water.

Through the hose, at least three liquids can be fed separately from one another through a single hose to the at least one outlet opening, which reduces the space required in the fitting housing or the outlet. The hose can have an outer diameter of, for example, 12 mm to 18 mm, preferably 14 mm to 15 mm. A first cross section of the first lumen can be semicircular. The first cross section is in particular aligned orthogonally to a longitudinal axis of the hose. A second cross section of the second lumen and/or a third cross section of the third lumen can be designed to be part-circular. The at least one further lumen can be designed in a part-circle shape. In particular, the second cross section of the second lumen and/or the third cross section of the third lumen can be designed in the shape of a quarter circle. The second cross section and/or the third cross section are in particular aligned orthogonally to the longitudinal axis of the hose.

The first lumen is separated from the second lumen, the third lumen and/or the at least one further lumen, in particular by a first partition. The second lumen, third lumen and/or the at least one further lumen are separated from one another in particular by at least one second partition. The first partition has in particular a first thickness of, for example, 1 mm to 1.5 mm and/or the second partition has in particular a second thickness of, for example, 1 mm to 1.5 mm.

The first lumen, second lumen, third lumen and/or the at least one further lumen can each have an inner wall oriented in the direction of the outer surface of the tube with a lumen radius. The lumen radius can be, for example, 4 mm to 8 mm, preferably 5 mm to 6 mm, particularly preferably (approximately) 5.5 mm.

First corners of a first cross section of the first lumen, second corners of a second cross section of the second lumen and/or third corners of a third cross section of the third lumen may have a radius of 0.4 mm to 0.6 mm. Preferably the radius can be (approximately) 0.5 mm. This makes it possible to reduce the flow resistance of the liquid in the lumen without reducing the cross-sectional area of the individual lumens too much.

The sanitary fitting has an adapter with at least a first inlet for the first lumen, a second inlet for the second lumen and a third inlet for the third lumen. The adapter can have one, more or even all of the following properties:

• - at least partially made of plastic and/or metal, such as brass;
• - be designed in the manner of a plastic injection molded part;
• - be formed in one piece;
• - have at least one further inlet for the at least one further lumen;
• - have a number of inlets corresponding to a number of lumens of the tube;
• - extend along a longitudinal axis;
• - (in particular parallel to the longitudinal axis) have a length of 10 mm to 60 mm;
• - (in particular orthogonal to the longitudinal axis) have a diameter of 5 mm to 50 mm;
• - have a round peripheral surface;
• - Have a first external thread or first internal thread.

The at least one first inlet, second inlet, third inlet and/or further inlet can be formed on a first longitudinal end of the adapter. The first inlet, second inlet, third inlet and/or further inlet can be designed in the manner of an opening and/or in the manner of a channel in the adapter. The tube is in particular connected to the adapter in such a way that the first lumen is connected to the first inlet, the second lumen is connected to the second inlet and the third lumen is connected to the third inlet. Furthermore, the hose can in particular be connected to the adapter in such a way that the at least one further lumen is connected to the at least one further inlet. This allows the first liquid to flow from the first lumen (in particular directly) into the first inlet, the second liquid from the second lumen (in particular directly) into the second inlet, the third liquid from the third lumen (in particular directly) into the third inlet and /or the at least one further liquid flows from the at least one further lumen (in particular directly) into the at least one further inlet. The connection between the hose and the adapter can, for example, be designed in the manner of a plug connection, clamp connection, adhesive connection, screw connection and/or bayonet connection.

The first inlet and the second inlet open into a first outlet. The first inlet and the second inlet thus open into a common first outlet. The first liquid and the second liquid can thereby flow into the first outlet and/or leave the adapter via the first outlet. The third inlet opens into a second outlet of the adapter. The third liquid can thereby flow into the second outlet and/or leave the adapter via the second outlet. The first liquid and the second liquid can be fed via the first outlet of the adapter, in particular to a (common) first outlet opening of the sanitary fitting or at least to a (common) first liquid channel of a mousseur of the sanitary fitting. The third liquid can be fed via the second outlet of the adapter, in particular to a second outlet opening of the sanitary fitting or at least to a second liquid channel of the mousseur of the sanitary fitting. The adapter can have at least one more inlet than outlets. At least some of the inlets can flow into at least one common outlet. The adapter can thereby reduce a number of outlet openings of the sanitary fitting and/or a number of (in particular separate) liquid channels in the mousseur.

The first inlet can be designed in the form of a first connection nipple, the second inlet in the form of a second connection nipple and the third inlet in the form of a third connection nipple, with the hose with the first lumen on the first connection nipple and with the second lumen on the second connection nipple and the third lumen is plugged into the third connection nipple. The at least one further inlet can be designed in the form of at least one further connection nipple, with the hose having the at least one further lumen on the at least one white can be plugged into the external connection nipple. The connection nipples can in particular be tubular and/or extend in the direction of the longitudinal axis of the adapter. The connection nipples can have, for example, a connection nipple length of 1 mm to 15 mm (in particular parallel to the longitudinal axis). Outer contours of the connection nipples can be designed to be congruent with inner contours of the lumens.

The first outlet of the adapter and the second outlet of the adapter can be formed coaxially with one another.

The first outlet of the adapter may extend around the second outlet of the adapter. The first outlet can be at least partially designed in the manner of an annular channel, at least partially have a straight course and/or extend at least partially parallel to the longitudinal axis. The second outlet can at least partially have a straight course and/or extend at least partially parallel to the longitudinal axis.

The first outlet of the adapter can open into at least a first liquid channel of a mousseur and the second outlet of the adapter can open into at least a second liquid channel of the mousseur. At least one further outlet of the adapter can open into at least one further liquid channel of the mousseur. The at least one first liquid channel, the at least one second liquid channel and/or the at least one further liquid channel can at least partially have a straight course and/or extend at least partially parallel to the longitudinal axis of the adapter. The at least one first liquid channel, the at least one second liquid channel and/or the at least one further liquid channel can open into an environment of the sanitary fitting. As a result, the liquids can be released into the environment via the liquid channels. The mousseur can be designed like an aerator. The adapter is in particular connected to the mousseur in such a way that the first outlet of the adapter is connected to the at least one first liquid channel of the mousseur, the second outlet of the adapter is connected to the at least one second liquid channel of the mousseur and/or the at least one further outlet of the adapter is connected to the at least one further liquid channel of the mousseur is connected. This allows the first liquid and second liquid to flow from the first outlet of the adapter (in particular directly) into the at least one first liquid channel of the mousseur and/or the third liquid from the second outlet of the adapter (in particular directly) into the at least one second liquid channel of the mousseur stream. The connection between the adapter and the mousseur can, for example, be designed in the manner of a plug connection, clamp connection, adhesive connection, screw connection and/or bayonet connection.

The at least one first liquid channel of the mousseur can extend around the at least one second liquid channel of the mousseur. The mousseur can have a single first liquid channel and/or a plurality of second liquid channels, wherein the plurality of second liquid channels can in particular be arranged in a ring shape around the first liquid channel.

The adapter can be attached to the hose using a union nut. For this purpose, the union nut can be placed on the hose and/or screwed to the adapter. For this purpose, the union nut can have a second internal thread or a second external thread. The union nut can be at least partially sleeve-shaped.

A clamping ring can be arranged between the adapter and the union nut. The clamping ring can be ring-shaped, placed on the hose and/or pressed against the hose by the union nut.

A spacer can be arranged between the adapter and the union nut. The spacer can be ring-shaped, placed on the hose and/or arranged next to the clamping ring (parallel to the longitudinal axis).

A crimping ring can be arranged between the adapter and the union nut. The crimping ring can be ring-shaped, placed on the hose and/or arranged next to the adapter (parallel to the longitudinal axis).

An annular seal can be arranged between the spacer and the crush ring.

The invention and the technical environment are explained in more detail below using the figures. It should be noted that the figures show a particularly preferred embodiment variant of the invention, but this is not limited to this. The same components in the figures are given the same reference numbers. They show by way of example and schematically:

• 1 : a sanitary fitting in a side view;
• 2 : a hose of the plumbing fitting in a cross section;
• 3 : an adapter of the sanitary fitting in a first perspective view;
• 4 : the adapter of the sanitary fitting in a second perspective view;
• 5 : a sectional view of a spout of the sanitary fitting; and
• 6 : the spout of the sanitary fitting with a view of a mousseur.

The 1 shows a sanitary fitting 1 in a side view. The sanitary fitting 1 has a fitting housing 2, which includes a rotatably mounted outlet 3 with an outlet opening 4. The fitting housing 2 can be attached to a support, not shown here. A hose 5 runs through the sanitary fitting 1 and is in the 2 shown first lumen 6 at a first longitudinal end 25 of the tube 5 with a first liquid source 27, which is in the 2 shown second lumen 7 at the first longitudinal end 25 of the tube 5 with a second liquid source 28 and its in the 2 shown third lumen 8 are connected to a third liquid source 29 at the first longitudinal end 25 of the tube 5.

The 2 shows a dem in the 1 shown first longitudinal end 25 opposite second longitudinal end 26 of the hose 5 in a perspective view. The first lumen 6 of the tube 5 is semicircular. The second lumen 7 and the third lumen 8 are quarter-circle shaped. The lumens 6, 7, 8 each include an inner wall 31 oriented in the direction of an outer surface 30 of the tube 5 with a lumen radius 32 around a center of the tube 5. The tube 5 has a casing 33 on its outer surface 30. The first lumen 6 is separated from the second lumen 7 and third lumen 8 by a first partition 34. The second lumen 7 and the third lumen 8 are separated from each other by a second partition 35.

The 3 shows the adapter 9 in the 1 shown sanitary fitting 1 in a first perspective view with a view of a third longitudinal end 36 of the adapter 9. The adapter 9 comprises a first inlet 10 designed in the form of a first connecting nipple 15, a second inlet 11 designed in the form of a second connecting nipple 16 and an in Formed third inlet 12 in the form of a third connection nipple 17. A first outer contour of the first connection nipple 15 is congruent to a first inner contour of the 2 shown first lumen 6, a second outer contour of the second connection nipple 16 congruent to a second inner contour of the in the 2 shown second lumen 7 and a third outer contour of the third connection nipple 17 congruent to a third inner contour of the in the 2 shown third lumen 8 formed. This makes it in the 2 hose 5 shown can be plugged with the first lumen 6 onto the first connecting nipple 15, with the second lumen 7 onto the second connecting nipple 16 and with the third lumen 8 onto the third connecting nipple 17. This allows a first liquid to flow from the first lumen 6 into the first inlet 10, a second liquid from the second lumen 7 into the second inlet 11 and a third liquid from the third lumen 8 into the third inlet 12.

The 4 shows the adapter 9 in a second perspective view with a view of a fourth longitudinal end 37 of the adapter 9. The adapter 9 comprises an annular first outlet 13, into which the in the 3 shown first inlet 10 and second inlet 11 open, and a second outlet 14, into which the in the 3 shown third inlet 12 opens.

The union nut 21 is screwed onto the adapter 9, so that the hose 5 is clamped to the adapter 9 and cannot detach from the adapter 9.

A mousseur 19 is plugged onto the fourth longitudinal end 37 of the adapter 9, so that the first outlet 13 of the adapter 9 has a plurality of first liquid channels 18 of the mousseur 19 and the second outlet 14 of the adapter 9 has a second liquid channel 20 of the mousse seurs 19 is connected. As a result, the first liquid and the second liquid can be delivered to an environment 41 via the first liquid channels 18 and the third liquid can be delivered to an environment 41 via the second liquid channel 20. The mousseur 19 forms the outlet opening 4 of the outlet 3.

The 6 shows the outlet 3 with a view of the mousseur 19. The plurality of first liquid channels 18 are formed concentrically around the second liquid channel 20 and concentrically to the longitudinal axis 38. The second liquid channel 20 is concentric to the longitudinal axis 38.

Thanks to the present invention, the liquids can be directed to the outlet opening 4 with less space required. In addition, the adapter 9 can reduce the complexity of the mousseur 19.
