SANITARY FITTING WITH ONE HOSE

Description

[0001] The present invention relates to a sanitary fitting which can be used in particular in connection with sinks and / or wash basins.

[0002] Sanitary fittings are used in sinks, wash basins, bathtubs, and / or showers to provide a liquid, especially water, as needed. For this purpose, sanitary fittings may have a housing with a spout and an outlet opening for the liquid. The housing of the sanitary fitting can be attached to a support, such as a countertop or a sink or wash basin. Furthermore, sanitary fittings may have a mixing valve or a mixing cartridge, which allows cold and hot water to be mixed to produce mixed water at a desired temperature.

[0003] Sanitary fittings are also known that can be used to dispense various liquids, such as mixed water, carbonated liquid, flavored liquid, filtered liquid, chilled liquid, and / or hot water. To convey the various liquids from their respective sources to the outlet, multiple liquid lines are required, running parallel to one another through the fitting body and / or the outlet. This results in a significant amount of space being required for the liquid lines, which limits the design freedom of the fitting bodies and outlets. Furthermore, the individual liquids can be dispensed via separate outlet openings on the sanitary fittings or via a mousseur on the sanitary fittings, so that they do not come into contact with one another or mix with one another prior to dispensing.If a large number of liquids 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.

[0004] From US2022049479A a sanitary fitting according to the preamble of claim 1 is known.

[0005] 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 multiple liquids can be guided to the outlet opening with less space required and which has a lower complexity.

[0006] These objects are achieved 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 expedient manner and define further embodiments of the invention. Furthermore, the features listed in the patent claims are further specified and explained in the description, with further preferred embodiments of the invention being presented.

[0008] The sanitary fitting is used in particular for the demand-based provision of liquids, such as water, to sinks and / or wash basins. The sanitary fitting comprises a fitting housing, which can in particular be made at least partially of plastic and / or (cast) metal, such as brass. The fitting housing can be fastened to a support, for example a worktop, the sink or wash basin, and / or has a (protruding or branching) outlet that is rigidly or movably connected to the fitting housing. The outlet can be at least partially tubular and / or has at least one outlet opening. The at least one outlet opening can, for example, be designed in the manner of a jet former or mousseur.

[0009] The sanitary fitting has a hose. The hose can extend at least partially through the fitting housing and / or the outlet. The hose has, in particular, a round cross-section. The hose is, in particular, made at least partially of a material approved and / or suitable for drinking water. The hose material can have at least one, several, or even all of the following properties: be temperature-resistant at -40 °C to 200 °C [Celsius]; be translucent; be elastic; have a hardness of 70 to 85 Shore A; have a density of 1.22 g / cm 3 < [grams per cubic centimeter] to 1.26 g / cm 3 < , preferably (approximately) 1.24 g / cm 3 <; have a tear strength of 8.6 N / mm 2 < [Newtons per square millimeter] to 8.8 N / mm 2 < , preferably (approximately) 8.7 N / mm 2 <; have an elongation at break of 390% to 410%, preferably (approximately) 400%; and / or have a tear propagation strength of 30 N / mm [Newtons per square millimeter] to 34 N / mm, preferably (approximately) 32 N / mm.

[0010] The tube has at least a first lumen for conducting a first liquid from a first liquid source to the outlet opening, a second lumen for conducting a second liquid from a second liquid source to the outlet opening, and a third lumen for conducting a third liquid from a third liquid source to the outlet opening. In addition, the tube can have at least one further lumen for conducting at least one further liquid from at least one further liquid source. The lumens are each, in particular, a (tubular) liquid channel that 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 tube can be connected to the first liquid source, second liquid source, and third liquid source (and optionallythe at least one further liquid source). Alternatively, the first longitudinal end of the hose can be connected to a distributor device for the at least one first liquid source, second liquid source and third liquid source (and optionally 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 optionally 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 hose. The lumens are in particular (jointly) formed in one piece by the material of the hose. The lumens in particular do not run concentrically to one another. The hose can be designed in the manner of a multi-lumen hose orMulti-lumen tube and / or not rotationally symmetrical.

[0011] 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. By means of 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, chilled liquid (for example, with a cooling water temperature of 1°C 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.

[0012] The hose allows at least three liquids to be supplied separately from one another through a single hose to the at least one outlet opening, thereby reducing 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 part-circular. The at least one further lumen can be part-circular. In particular, the second cross section of the second lumen and / or the third cross section of the third lumen can be quarter-circular.The second cross-section and / or the third cross-section are in particular aligned orthogonally to the longitudinal axis of the hose.

[0013] 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.

[0014] The first lumen, second lumen, third lumen, and / or the at least one further lumen can each have an inner wall oriented toward 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.

[0015] 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 can have a radius of 0.4 mm to 0.6 mm. Preferably, the radius can be (approximately) 0.5 mm. This allows the flow resistance of the fluid in the lumen to be reduced without excessively reducing the lumen cross-sectional area of ​​the individual lumens.

[0016] The sanitary fitting comprises 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 may have one, several, or even all of the following features: consist at least partially 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 that corresponds 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 circumferential surface; have a first external thread or first internal thread.

[0017] The at least one first inlet, second inlet, third inlet and / or further inlet can be formed at a first longitudinal end of the adapter. The first inlet, second inlet, third inlet and / or further inlet can be formed 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 tube 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.As a result, the first liquid can 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 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 be designed, for example, in the form of a plug-in connection, clamp connection, adhesive connection, screw connection, and / or bayonet connection.

[0018] The first inlet and the second inlet open into a first outlet. Thus, the first inlet and the second inlet 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. Via the first outlet of the adapter, the first liquid and the second liquid can be fed 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. Via the second outlet of the adapter, the third liquid can be fed 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 lead into at least one common outlet. The adapter can thus reduce the number of outlet openings of the sanitary fitting and / or the number of (particularly separate) fluid channels in the mousseur.

[0019] 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, wherein the tube with the first lumen is plugged onto the first connection nipple, with the second lumen onto the second connection nipple, and with the third lumen onto the third connection nipple. The at least one further inlet can be designed in the form of at least one further connection nipple, wherein the tube with the at least one further lumen can be plugged onto the at least one further 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, for example, have 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 congruent with inner contours of the lumens.

[0020] The first outlet of the adapter and the second outlet of the adapter can be coaxial with each other.

[0021] The first outlet of the adapter can extend around the second outlet of the adapter. The first outlet can be at least partially configured as an annular channel, at least partially have a straight path, and / or extend at least partially parallel to the longitudinal axis. The second outlet can at least partially have a straight path and / or extend at least partially parallel to the longitudinal axis.

[0022] The first outlet of the adapter can open into at least one first liquid channel of a mousseur and the second outlet of the adapter can open into at least one 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 in the manner of an aerator.The adapter is connected to the mousseur in particular such 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. As a result, the first liquid and second liquid can 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 can flow from the second outlet of the adapter (in particular directly) into the at least one second liquid channel of the mousseur. The connection between the adapter and the mousseur can be designed, for example, in the manner of a plug-in connection, clamp connection, adhesive connection, screw connection and / or bayonet connection.

[0023] 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 be arranged in particular in a ring shape around the first liquid channel.

[0024] The adapter can be attached to the hose using a union nut. The union nut can be pushed onto the hose and / or screwed to the adapter. The union nut can have a second internal thread or a second external thread. The union nut can be at least partially sleeve-shaped.

[0025] 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.

[0026] A spacer can be arranged between the adapter and the union nut. The spacer can be ring-shaped, placed on the hose, and / or positioned next to the clamping ring (parallel to the longitudinal axis).

[0027] A compression ring can be arranged between the adapter and the union nut. The compression ring can be ring-shaped, placed on the hose, and / or positioned next to the adapter (parallel to the longitudinal axis).

[0028] An annular seal may be arranged between the spacer and the compression ring.

[0029] The invention and the technical environment are explained in more detail below with reference to the figures. It should be noted that the figures show a particularly preferred embodiment of the invention, but are not limited thereto. Identical components in the figures are provided with the same reference numerals. They show, by way of example and schematically: Fig. 1: a sanitary fitting in a side view; Fig. 2: a hose of the sanitary fitting in a cross-section; Fig. 3: an adapter of the sanitary fitting in a first perspective view; Fig. 4: the adapter of the sanitary fitting in a second perspective view; Fig. 5: an outlet of the sanitary fitting in a sectional view; and Fig. 6: the outlet of the sanitary fitting with a view of a mousseur.

[0030] The Fig. 1 shows a sanitary fitting 1 in a side view. The sanitary fitting 1 has a fitting housing 2, which comprises a rotatably mounted outlet 3 with an outlet opening 4. The fitting housing 2 can be fastened to a support (not shown here). A hose 5 runs through the sanitary fitting 1, the hose 5 being Fig. 2 shown first lumen 6 at a first longitudinal end 25 of the tube 5 with a first liquid source 27, the Fig. 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 Fig. 2 shown third lumen 8 at the first longitudinal end 25 of the tube 5 are connected to a third liquid source 29.

[0031] The Fig. 2 shows a Fig. 1 1 shows a perspective view of the second longitudinal end 26 of the tube 5, opposite the first longitudinal end 25 shown. The first lumen 6 of the tube 5 is semicircular. The second lumen 7 and the third lumen 8 are quarter-circular. The lumens 6, 7, 8 each comprise an inner wall 31 oriented towards an outer surface 30 of the tube 5 and having 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 one another by a second partition 35.

[0032] The Fig. 3 shows the adapter 9 of the Fig. 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 formed in the form of a first connection nipple 15, a second inlet 11 formed in the form of a second connection nipple 16 and a third inlet 12 formed in the form of a third connection nipple 17. A first outer contour of the first connection nipple 15 is congruent with a first inner contour of the Fig. 2 shown first lumen 6, a second outer contour of the second connection nipple 16 congruent to a second inner contour of the Fig. 2 shown second lumen 7 and a third outer contour of the third connection nipple 17 congruent to a third inner contour of the Fig. 2 The third lumen 8 shown in the figure is formed. Fig. 2 The tube 5 shown can be plugged with the first lumen 6 onto the first connection nipple 15, with the second lumen 7 onto the second connection nipple 16, and with the third lumen 8 onto the third connection 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.

[0033] The Fig. 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 Fig. 3 shown first inlet 10 and second inlet 11 open, and a second outlet 14, into which the Fig. 3 shown third inlet 12 opens. This allows the first liquid to flow via the first inlet 10 into the first outlet 13, the second liquid to flow via the second inlet 11 into the first outlet 13, and the third liquid to flow via the third inlet 12 into the second outlet 14. The first outlet 13 and the second outlet 14 are concentric to one another and concentric to a longitudinal axis 38 of the adapter 9.

[0034] The Fig. 5 shows the outlet 3 of the sanitary fitting 1 in a Fig. 1 with a circle 39 in a sectional view. The hose 5 is connected with its second longitudinal end 26 to the Fig. 3 shown connection nipples 15, 16, 17 and fastened to the adapter 9 with a union nut 21. A clamping ring 22, an annular spacer 23, an annular seal 40, and a compression ring 24 are arranged between the adapter 9 and the union nut 21. The clamping ring 22, the annular spacer 23, the annular seal 40, and the compression ring 24 are arranged next to one another in the direction of the longitudinal axis 38 of the adapter 9 and the union nut 21, respectively. The union nut 21 is screwed onto the adapter 9 so that the hose 5 is clamped to the adapter 9 and cannot come loose from the adapter 9.

[0035] 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 is connected to a plurality of first liquid channels 18 of the mousseur 19, and the second outlet 14 of the adapter 9 is connected to a second liquid channel 20 of the mousseur 19. As a result, the first liquid and the second liquid can be released into an environment 41 via the first liquid channels 18, and the third liquid via the second liquid channel 20. The mousseur 19 forms the outlet opening 4 of the outlet 3.

[0036] The Fig. 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 formed concentrically to the longitudinal axis 38.

[0037] The present invention allows the liquids to be directed to the outlet opening 4 with less space required. Furthermore, the adapter 9 reduces the complexity of the mousseur 19. Bezugszeichenliste
