Description

The present invention relates to a sanitary fitting according to the preamble of claim 1.

Sanitary fittings to the outlet of the water, in particular of mixed cold water and hot water mixed water are well known. For directing the mixed water flowing out of the sanitary fitting to different areas of the environment, sanitary fittings are usually equipped with a pivotable water outlet.

A sanitary fitting with such a pivotable water outlet is for example in the DE-A-4138938 disclosed. The sanitary fitting described therein has a mounting base, are guided into the water supply lines, a control cartridge and a pivotable about the central axis of a valve body main body. The outlet pipe is fastened to a valve body rotatably mounted on the valve body. The mixed water passes from the control cartridge through a passage in the fitting base body, further through a trained in a bearing recess of the fitting main body Mitnehmerbuchse on an inside of the sleeve together with the outlet pipe attached Winkelrohrelement and leaves the sanitary fitting via the outlet pipe.

EP-A-0 061 562 discloses a mixer tap for vanity units, sink units, etc. with a valve body comprising a mixed water outlet associated with an outlet. The outlet has a tubular connection piece and is optionally arranged pivotally.

DE-U-297 07 764 discloses a faucet with a hood and a mixing cartridge disposed therein, which is flow connected via a connecting element with a water spout.

Object of the present invention is to provide a sanitary fitting with a simple structure, even with frequent pivoting of their water outlet sealed in the long term against unwanted water leakage and inexpensive to produce.

This object is achieved by a sanitary fitting according to claim 1. Particularly preferred embodiments are equipped with features mentioned in the dependent claims.

The inventive sanitary fitting is equipped with a seated on a valve body control cartridge, by means of which an outflow of water, especially mixed water, is controlled from the sanitary fitting. On the output side of the control cartridge, the mixed water is passed through a discharge-side passage in the valve body in an inflow side pipe leg of a one-piece angle pipe element. The angle tube element is fluidically connected to a water outlet through which the mixed water flows into the environment. Due to the one-piece design of the angle tube element, this is particularly simple, for example by means of an injection molding technique, and thereby very cost-effectively.

The outflow-side passage is equipped in the direction of the angle tube element with a bearing recess in which the inflow-side tube leg is rotatably mounted about a pivot axis. In this case, the longitudinal axis of the flow-side pipe leg is coaxial with the pivot axis. Together with the inflow-side tube leg, the water outlet connected to the angle tube element can also be pivoted about the pivot axis. The rotatable mounting of the inflow-side tube leg in the bearing recess saves the installation of further connecting elements between the valve body and the angle tube element, which in turn reduces manufacturing costs. At the same time thereby the use of a single dynamic sealing element in the bearing recess between the inflow side pipe leg and the valve body is possible. The dynamic sealing element is protected in the bearing recess from environmental influences and has relatively small dimensions with respect to the sanitary fitting. Due to its small dimensions, the dynamic sealing element can be produced at lower tolerances cost and causes a more reliable seal with a longer life than comparatively large sealing elements.

Sanitary fitting intended for wall mounting.

In the Fig. 1 in a longitudinal section shown inventive sanitary fitting is designed for Auftischmontage. In her lower, a water inlet 10 of the sanitary fitting facing end region, it has in this regard a mounting sleeve 12 with a in Fig. 1 not shown external thread on. For mounting the Santitärarmatur the mounting sleeve 12 is guided by a corresponding implementation in a pad, for example in a vanity, and secured with a screwed onto the outer thread of the mounting sleeve 12 on the underside union nut.

The guided through the mounting sleeve 12, realized via supply pipes water inlet 10 for cold water KW and / or hot water WW is connected upstream with a corresponding piping system for water supply. Downstream of the water inlet 10 passes through a arranged above the mounting sleeve 12 bearing plate 14 and is sealingly inserted into an inflow-side passage 16 of above the bearing plate 14 arranged fitting body 18. For this purpose, the supply pipes of the water inlet 10 are soldered into the or the inflow-side passages 16, welded, screwed or glued.

The inflow-side passage 16 leads the cold water KW and / or the hot water WW to the input of a control cartridge 20. Such a control cartridge 20 is for example in the CH-A-691 134 described. It allows by a manual intervention of a user and / or technical Adjusting means on the one hand, a control of a mixing ratio of fed via the water inlet 10 cold water KW and hot water WW for providing mixed water MW and on the other hand, an adjustment of the flow rate of the effluent through the sanitary fitting mixed water MW. By controlling the mixing ratio of cold water KW and DHW WW, the temperature of the effluent mixed water MW is determined.

The control cartridge 20 is sealingly placed on a seat arranged opposite the water inlet 10 28 of the fitting body 18. On the output side of the control cartridge 20, the mixed water MW is discharged through a discharge-side passage 30 in the valve body 18. Thus communicate flow-related in each case inflow-side passages 16 of the fitting body 18 for cold water KW and hot water WW input side and the discharge-side passage 30 of the fitting body 18 for mixed water MW output side with associated inputs and an output of the control cartridge 20th

The control cartridge 20, the valve body 18, the bearing plate 14 and the mounting sleeve 12 are arranged in a hollow cylindrical inner sleeve 32 while supported against each other or fixed in position to each other. Concentric with respect to the inner sleeve 32 encloses a likewise cylindrical Armaturaussenhülse 36, the inner sleeve 32nd

The fitting outer sleeve 36 is pivotable in its free end regions in each case by means of sliding rings 38 about the coaxially extending cylinder axes of Armaturaussenhülse 36 and the inner sleeve 32 mounted on the inner sleeve 32 outside. At the fitting outer sleeve 36 a pointing away from the pivot axis S outlet nozzle 40 of a water outlet 42 to be described later in detail integrally formed.

In the outflow-side passage 30 of the fitting body 18, a cylindrical bearing recess 44 is formed in a downstream end region. In the bearing recess 44 engages an inflow-side end portion of an inflow-side tube leg 46, which is formed on a one-piece angle tube member 48, rotatably or pivotally about a pivot axis S a. The pivot axis S is defined by the cylinder axes of the inflow-side tube leg 46 and the Armaturaussenhülse 36. It coincides with the cylinder axes of the inner sleeve 32 and bearing recess 44th

In the bearing recess 44 between the inflow-side end region of the inflow-side tube leg 46 and the fitting base body 18, a dynamic sealing element in the form of a sealing ring 49 is arranged. The sealing ring 49 prevents leakage of mixed water MW from the inflow side tube leg 46 in the bearing recess 44 and is the only when pivoting the inflow-side tube leg 46 and the water outlet connected to it 42 dynamically stressed sealing element.

Due to this single dynamic sealing element, the internal structure of the sanitary fitting can be simplified and cost-effective production of the sanitary fitting is possible. In addition, in the inventive Sanitary fitting the only dynamic sealing element disposed within the inner sleeve 32, whereby a smaller diameter of the dynamic sealing element compared to known sanitary fittings with a ring channel is made possible. Since sealing elements with smaller dimensions can be manufactured within smaller tolerances and with lower manufacturing costs, the life increases and also reduce the production costs for the sanitary fitting according to the invention.

At its end region opposite the bearing recess 44, a bearing journal 50 is formed on the inflow-side tube leg 46. This cylindrical bearing journal 50 rotatably engages in a bearing-like recess 52 of the bearing plate 14 arranged centrally with respect to the pivot axis S. At the same time, the inflow-side tube leg 46 is axially supported by the bearing plate 14. As a result, thus the inflow-side tube leg 46 and further the entire angle tube member 48 is rotatably supported on the one hand in the bearing recess 44 of the valve body 18 and on the other hand in the bearing-like recess 52 of the bearing plate 14.

The mixed water MW flows from the inflow-side tube leg 46 into a drain-side tube leg 54 of the angled tube element 48 which projects away from the pivot axis S. The coaxial with the pivot axis S extending cylinder axis of the inflow side tube leg 46 forms with the cylinder axis of the outlet side tube leg 54 has a fixed angle between 80 ° and 90 °, preferably of 80 °. The two tube legs 46, 54 and beyond the whole angle tube 48 are made a plastic, preferably made of polyacetal (POM).

In the outflow-side tube leg 54, a connecting tube 56 of the water outlet 42 is sealingly joined up to a shoulder 58 in the outflow side tube leg 54. In order to prevent unwanted leakage of mixed water MW in a corresponding joining region in which the free end region of the outflow-side tube leg 54 sleeve-like receives the tubular leg end portion of the connecting tube 56, as static sealing element, an O-ring 60 in a groove in arranged tube side end portion of the connecting tube 56.

The connecting tube 56 is guided coaxially in the outlet connection 40 by a guide ring 62 formed inside the outlet connection 40. It discharges downstream into an outlet channel 64 of an outlet end piece 66 mounted in the free end region of the outlet nozzle 40. The outlet end piece 66 is made of a plastic, preferably of acrylic butadiene styrene (ABS).

The outlet end 66 is rotatably mounted about a rotation axis D in the outlet pipe 40. The axis of rotation D is determined by the coaxial cylinder axes of the connecting tube 56 and the outlet nozzle 40.

The rotatable mounting of the outlet end piece 66 is formed by a tailor-made, longitudinal insertion of a connection pipe side formed at the outlet end piece 66 pipe extension 68 in the free end of the Outlet stub 40 causes. In addition to the pivotability of the water outlet 42 with respect to the pivot axis S is provided by the rotation of the outlet end 66 with respect to the rotation axis D, an additional degree of freedom for a spatial alignment of the effluent mixed water MW.

By simultaneously precisely fitting-sealing concerns a radially inner wall 69 of the pipe socket 68 on the connecting pipe 56, supported by a radially outwardly in a groove 70 of the connecting pipe 56 arranged static sealing element in the form of another O-ring 72, the connecting pipe 56 in the outlet end 66th sealed.

As in Fig. 2 shown, a rotation angle about the rotation axis D can be limited to a range of about -60 ° to + 60 ° and thus a total of about 120 °. For this purpose, a stop screw 74 is screwed in the free end region of the outlet nozzle 40. A virtually half-circumferential circumferential, radially outwardly on the pipe extension 68 recessed further groove 76 allows rotation of the outlet end 66 about the rotation axis D to the reaching into the groove 76 stop screw 74 by a stop on each end of the groove 76 formed stop sides 78 limit the angle of rotation.

In the outlet end piece 66, the outlet channel 64 for the mixed water MW opens through a water outlet opening 80 oriented at right angles to the rotation axis D. The water outlet opening 80 is provided with an internal thread which can be screwed with an external thread of a mouthpiece 82 which can be screwed into the water outlet opening 80 interacts. In the in Fig. 1 Unillustrated mouthpiece 82 may be various types of beam forming or filter elements used before the outlet of the mixed water MW in the environment.

A filter element in the form of a Legionella filter 84 is used interchangeably directly or near the water outlet opening 80 in the outlet channel 64 of the outlet end piece 66. By means of the Legionella filter 84 in the form of a metallic grid coated with a silver layer, legionella (rod-shaped bacteria causing Legionnaires' disease) possibly brought in from the connecting tube 56 with the mixed water MW are killed. The arrangement of the Legionella filter 84 in the immediate vicinity of the water outlet opening 80 also prevents recontamination of upstream of the water outlet opening 80 disposed water-conducting elements.

With respect to the axis of rotation D diametrically opposite the water outlet opening 80, a transparent window 86 is arranged in the outlet end piece 66. The transparent window 86, which is made of a plastic, preferably made of Plexiglas (polymethyl acrylate), allows a view of the Legionellenfilter 84 arranged in the outlet channel 64 and thereby allows an optical control of the state of the legionella filter 84. With a corresponding discoloration of the silver layer of the Legionella filter 84, the outlet end 66 can be pulled out of the outlet nozzle 40 after unscrewing the stop screw 74, and the Legionella filter 84 inserted and used in the outlet channel 64 can be exchanged.

As the angle of rotation of the outlet end 66 about the axis of rotation D is also a pivot angle of the water outlet 42 about the pivot axis S limited. This is, as in the sectional view in Fig. 3 shown, a stopper pin 88 radially inserted through the inner sleeve 32 into the fitting body 18 inserted. Radially formed inside the Armaturaussenhülse 36 stops 90 cooperate with the projecting into a space between the Armaturaussenhülse 36 and the inner sleeve 32 stop pin 88 and limit the Verschwenkungswinkel in a range of about -40 ° to about + 40 °.

As in particular in Fig. 3 shown, neither the Armaturaussenhülse 36 nor the outlet pipe 40 is water-bearing. For this reason, completely dispense with the outer fitting sleeve 36 associated dynamic sealing elements with a large diameter, simplifies the structure and thus the inventive sanitary fitting can be produced inexpensively.

The truncated, hollow cylindrical inner sleeve 32 has in the sectional view of Fig. 3 a semicircular, to the pivot axis S out and open broken only by the stopper pin 88 circular ring half. Connecting pipe side, opposite the cut circular ring half, there is a recess in the inner sleeve 32, which is necessary for the pivotability of the outflow side tube leg 54 of the angle tube member 48 and the connecting tube 56.

Also, the fitting body 18, are shown in the circular passages of the water inlet 10 for cold water KW and hot water WW, is due to a pivotable for the pivoting tube member 48 and the connecting tube 56 necessary, wedge-shaped recess to the pivot axis S out. Therein, in the direction of the stop pin 88 has also wedge-shaped cut angle tube member 48 with its outside in the cross-sectional rounded inflow side tube leg 46. Through the center of a circular inner cross section of the tube leg 46, the pivot axis S.

The limited by the interaction of the stops 90 with the stop pin 88 Verschwenkungswinkel is chosen such that it comes even at maximum Verschwenkungswinkel to no contact between the valve body 18 facing side surfaces of the Winkelrohrelements 48 and the valve body 18. As a result, forces which act tangentially with respect to the pivot axis S on the fitting base body 18 and the angular tube element 48 are prevented and correspondingly avoided deformations or leaks are avoided.

In Fig. 4 is a further embodiment of an inventive sanitary fitting, which is designed for wall mounting, shown. In this case, a wall connection 92 for carrying out the water flow 10 through a wall, a fastening nut 94 for attachment of the fitting body 18 to the water inlet 10 and the mouthpiece 82 is not shown cut.

Unlike in Fig. 1 to Fig. 3 shown inventive sanitary fitting for Auftischmontage here the water inlet 10 is oriented almost at right angles to the pivot axis S. For this reason, the fitting body 18 is angled accordingly and arranged both the inflow-side passage 16 as well as the seat 28 and the longitudinal axis of the control cartridge 20 almost at right angles with respect to the pivot axis S.

Like the inflow-side passage 46 of the fitting body 18, which simultaneously forms a housing of the sanitary fitting, the outflow-side passage 30 is widened spatially and merged water MW from a flow direction on the output side of the control cartridge 20, which is also oriented approximately perpendicular to the pivot axis S, in a Flow direction parallel to the pivot axis S.

At the outlet-side passage 30 of the fitting body 18, the bearing recess 44 is formed on the side of the tubular body. The inflow-side end region of the inflow-side tube leg 46 rotatably engages in the bearing recess 44. In the bearing recess 44 between the inflow-side end region of the inflow-side tube leg 46 and the fitting base body 18, in turn, only a single dynamic sealing element in the form of the sealing ring 49 acts.

Unlike in Fig. 1 to Fig. 3 In the embodiment shown in FIG Fig. 4 the bearing recess 44 in the direction of the pivot axis S winkelrohrelementseitig extended such that the fitting body 18, the angle tube member 48 to the the bearing recess 44 opposite end portion comprises sleeve-like. Only for the free pivoting of belonging to the water outlet 42 connecting pipe 56 has a corresponding recess in the sleeve-like end portion of the fitting body 18 is formed. The outflow-side tube leg 54 of the angle tube element 48 is here aligned inwards towards the pivot axis S and at right angles to the inflow-side tube leg 46.

The Armaturaussenhülse 36 is cup-shaped in this embodiment and has a bottom 96 on which a perpendicular to the pivot axis S oriented side surface 98 of the outflow pipe leg 54 comes into contact. The Armaturaussenhülse 36 is pivotally mounted on slide rings 38 between the Armaturaussenhülse 36 and the sleeve-like end portion of the valve body 18.

A stop screw 99 is screwed in this embodiment in the Armaturaussenhülse 36 and extends into a sleeve-like end portion of the fitting body 18 recessed sleeve groove 100 inside. In Fig. 4 not shown, circumferentially opposite abutment sides of the sleeve groove 100 limit in a stop of the stopper screw 99 to the abutment sides of the sleeve groove 100, the Verschwenkungswinkel.

The right-angled away from the pivot axis S outlet nozzle 40 is integrally formed on the Armaturaussenhülse 36 also in this embodiment. The connecting tube 56 is in the outlet pipe 40 also by means of a guide ring 62 which in Fig. 4 Not is shown, guided, upstream sealing inserted into the outflow side tube leg 54 and received in its end downstream sealing from the tube extension 68 of the outlet end 66.

The discharge end 66 is identical to the one in FIG Fig. 1 designed embodiment and also rotatably mounted about the rotational axis D, predetermined by the longitudinal axis of the outlet nozzle 40, stored in the outlet pipe 40.

Of course, in the described embodiments, alternatively, the outlet end 66 may be rotatably mounted on the outlet pipe 40. Likewise, it is of course also possible that the longitudinal axes of the outlet end 66 and the outlet nozzle 40 may be aligned at a predetermined angle to each other.

Likewise, the window 86 may alternatively be formed differently and the Legionella 84 be replaced by a different type of filter. Moreover, it is also conceivable to equip the discharge end piece 66 with protruding gripping elements, which facilitate turning of the discharge end piece 66 by the user.
