Description

Description Fitting with a swivel spout

The invention relates to a fitting with a swivel spout according to the preamble of claim 1.

In a fitting with swivel spout, the outer fitting housing can be pivotally mounted on a radially inner, pivot-fixed housing insert. In the housing insert, among other things, for example, a single-lever mixing cartridge is integrated with the operating lever, the temperature and / or amount of effluent mixed water is adjustable. From DE 10 2007 009 409 AI a generic fitting with swivel spout is known. An adapter is integrated into the housing insert for easy connection of the cold and hot water pipes to the mixing cartridge. On the input side of the adapter, the cold and hot water pipes are connected. On its output side, the adapter is in connection with the mixing cartridge. In addition, the adapter has a flow passage, which connects the mixing cartridge fluidly with a guided to the water outlet mixing water pipe.

In DE 10 2007 009 409 B4, the mixed-water flow passage in the adapter is an annular space running around the housing axis with a radially open flow area which is fluidically connected to a mixed water line leading to the water outlet. The cold and hot water channels of the adapter extend in the axial direction through the mixed water annulus. That is, the adapter-side cold and hot water channels are lapped by draining mixed water. In such a mixed water guide through the adapter of the annular space in the axial direction is sealed at the top and bottom, each with a ring seal against the inner wall of the valve body. The two ring seals are circumferentially positioned between the adapter outer circumference and the inner circumference of the fitting housing and therefore designed with a correspondingly large sealing diameter. This results in a pivoting operation comparatively large friction between the rotating valve body and the pivot-fixed housing insert, which can limit the ease of use. In addition, the impermeable seal can be carried out only with increased assembly-technical effort and material costs.

In the above-mentioned, known from the prior art fitting the mixed water is passed to the mixing cartridge through a housing insert to the water-conducting swivel outlet. As a result, the water is always in contact with the brass housing. The swivel spout is cast in common, costly practice brass or soldered together from two brass parts.

The object of the invention is to provide a low-cost sanitary fitting in which the waterway is separated from the metal of the fitting housing, whereby instead of brass, a cheaper zinc die-casting is used. In addition, another object is to simplify the assembly and manufacture of the valve body, specifically using a low cost zinc injection molding process. In addition, a fitting is to be provided in which the effort for sealing is reduced in a simple manner. The object is solved by the features of claim 1. Preferred embodiments of the invention are disclosed in the subclaims. According to the characterizing part of claim 1, the mixed water flow passage is formed in the adapter no more than a radially outwardly open annular space which can be sealed only with high assembly effort, but rather as a mixed water channel having a, open in the axial direction outlet opening. In this way, a downstream mixing water line can be connected to the mixing water outlet opening of the adapter with a sealing diameter that is much smaller than that of the prior art. By the present invention possible smaller seal diameter can thus be dispensed with, for example, expensive lip seals.

In a technical realization, the adapter may have a mixed water connection which delimits the outlet opening which is open in the axial direction. Furthermore, the adapter may have a cold water channel and a hot water channel, which connect the cold and hot water pipes with the valve member. The cold and hot water channels of the adapter can be limited by cold and hot water connection.

In the prior art hot water and cold water channels of the adapter are lapped by the outflowing mixed water. Such a mixed water flushing is omitted in the adapter geometry according to the invention. Here, in contrast to the prior art, the cold and hot water pipe can be arranged axially parallel to the mixing water pipe. With regard to a compact design, the hot and cold water nozzles can preferably be arranged eccentrically to the housing axis, while the mixed water nozzle are arranged centrally to the housing axis. The protruding from a main body of the adapter hot, cold and mixed water nozzles are preferably space-saving at one, the cold and hot water lines facing front side of the adapter arranged. To the mixed water outlet opening of the adapter can connect a mixed water line in the flow direction. This can be embodied as a conduit element separate from the fitting housing, for example as a water hose. The water hose can be guided continuously from the adapter to the outlet side jet former of the water outlet. In this way, the mixed water flowing out from the mixing cartridge can be guided without contact with respect to an inner wall of the fitting housing up to the water outlet opening. The use of such a mixed water line, the use of brass as a material for the valve body is no longer required, but is the use of a more cost-zinc armature housing possible.

The mixed water line can be designed differently. By way of example can be laid between the mixed water nozzle and the water outlet opening a uniform material and one-piece designed mixing water hose. In this case, the mixing water hose is to make sufficiently flexible, so that the connected to the pivot-fixed adapter mixing water hose line can follow a pivoting movement of the valve body permanently reliable.

In contrast to such a one-piece design of the mixed water line, it is preferred in terms of increased life, if the run to the water outlet, separate from the valve body mixing water pipe is formed in several parts with at least one Umlenkeinsatz. The deflecting insert may be pivotally mounted on the pivotable adapter at bearings. In a bearing eccentric with respect to the housing axis, compensating movements between the deflecting insert and the valve housing in the radial direction result in the case of a valve pivoting operation. This can lead to mechanical loads on the deflection insert. Against this background, a centric mounting of the deflection insert, ie coaxially with the housing axis, is preferred, as a result of which the compensation movements are eliminated. As the housing axis is to be understood in the present application, a pivot axis about which the valve body is rotatable in a user-side pivoting operation. Alternatively or additionally, the surface of the housing axis is to be understood as meaning a surface normal which passes through the center of gravity of a cross-sectional area through the valve. In the case of a hollow-cylindrical fitting housing whose central axis forms the housing axis.

The deflecting insert can also have a driver, by means of which the deflecting insert can be coupled in motion with the fitting housing in the pivoting direction. In this way, a permanently reliable flow connection between the adapter and the mixed water line is provided. In addition, the mixed water line is exposed to no mechanical stress due to pivotal actuations of the valve body. As a result of the driver, the water line possibly connected to the deflection insert is thus decoupled from all movement forces or moments which are caused by the rotation of the fitting housing.

The diverter insert may be liquid-tightly coupled to the inlet outlet opening with an inlet-side channel section and having an outlet-side channel section, to which, for example, a tubular water line can be connected, which is guided to the water outlet opening. With regard to a simple geometry, the inlet-side channel section of the deflecting insert in a double function can at the same time form a bearing point. For this purpose, the inlet-side channel portion is preferably coaxial with the housing axis in a pivotable and liquid-tight connector with the mixed water nozzle of the adapter, wherein the connector is designed to allow a pivoting movement of the deflecting insert. In order to form a further bearing point, the deflecting insert can have a bearing contour, that is to say, for example, a bearing journal, on its side which is axially opposite the inlet-side channel section. This can be pivotally mounted with movement play in a corresponding mating contour of a housing insert.

In a preferred technical embodiment, the adapter can be arranged together with the mixing cartridge in a housing insert. This is swivel-mounted in the installation position within the valve body. The housing insert can be designed as a hollow cylinder, the hollow profile of which defines a bottom of the insert on the bottom side and has an upwardly open end face, through which the adapter insert and the valve member can be inserted during assembly. The housing insert thus forms a stable support base for .the Ventilorgari, the adapter and the deflection insert. In addition, the insert bottom of the housing insert connecting connections for line connection between the inlet port of the adapter and the hot and cold water lines have. Furthermore, in the insert bottom of the housing insert, the countercontour cooperating with the bearing contour (for example a bearing journal) of the deflecting insert may be formed in the insert bottom of the housing insert.

The housing insert may be provided with pivot stops which limit pivotal movement of the valve body about the housing axis. For this purpose, the housing insert may have a radially outer circumferential groove, in which a stop screw of the valve body protrudes radially inwardly.

The advantageous embodiments and / or further developments of the invention explained above and / or reproduced in the dependent claims can be used individually or else in any desired combination with one another, for example in the case of clear dependencies or incompatible alternatives. The invention and its advantageous embodiments and developments and their advantages will be explained in more detail with reference to drawings.

In Fig. 1, a sanitary fitting with a fitting housing 1 and a molded water outlet 3 shown. The fitting housing 1 is a hollow profile part, for example made of zinc, with a cylindrical, upwardly open mounting space, which is bounded on the bottom side by a base plate 5. In the mounting space, a hollow cylindrical housing insert 7 is inserted, in the hollow profile of a single-lever mixing cartridge 9 and an adapter 11 is arranged. The hollow cylindrical mounting space of the fitting housing 1 is connected via a passage 13 (Fig. 2) with the water outlet 3 in connection. The mixing cartridge 9 is fluidly coupled with the interposition of the adapter 11 with a hot water pipe 15, a cold water pipe 17 and a guided to the water outlet 3 of the sanitary fitting mixing water pipe 19. The upwardly open mounting space of the valve body 1 is closed in Fig. 1 by a cap 21 through which a lever 23 of the mixing cartridge 9 protrudes upward. The consisting of the housing insert 7, the mixing cartridge 9 and the adapter 11 assembly is clamped in Fig. 1 by means of a top side of the valve body 1 arranged central screw 25 against the bottom-side mounting plate 5 of the valve body 1. By turning and / or tilting movements of the lever 23, the temperature and / or quantity adjustment of the mixed water flowing out of the water outlet 3 takes place in a manner known per se. The inner housing insert 7 is pivotally clamped by an indicated clamping screw 27 (FIG. 1 or 2) with a kitchen worktop 10, which is indicated only in FIG. In contrast, the hollow cylindrical fitting housing 1 is pivotally mounted about a housing axis A on the outer circumference of the housing insert 7, with the interposition of bearings 29 (Fig. 2).

As is apparent from FIGS. 1 or 2, the hollow profile of the housing insert 7 is bounded on the bottom side by an insert bottom 31. This has unillustrated connection connections, in the inserted from below fittings of the hot and cold water pipes 15, 17 are inserted liquid-tight and held captive by means of an insert 37 (Fig. 1 or 2). On the axially opposite side protrude hot and cold water pipe 39, 41 of the adapter 11 in the connection terminals of the insert bottom 31 a liquid-tight. The hot and cold water nozzles 39, 41 of the adapter 11 are in turn coupled liquid-tight at their outlets 43 (Fig. 6) to the mixing cartridge 9 and each define a hot water channel 48 and a cold water channel 44th

As is further apparent from FIGS. 5 to 8, the adapter 11 has a mixed water channel 45. This is guided starting from the mixing cartridge 9 along the housing axis A down _/ wherein the outlet opening 46 (Fig. 8) bounded by a mixed water pipe 47 is. The mixed water pipe 47 and the hot and cold water pipe 39, 41 are aligned parallel to each other with respect to the housing axis A axis parallel. In addition, the mixed water pipe 47 is arranged coaxially to the housing axis A, while the two hot and cold water pipe 39, 41 are arranged eccentrically thereto.

As is further apparent from FIG. 5, the adapter 11 has a stop contour 49. This is in the assembly position in contact with corresponding rotation stops 51 (FIG. 3), which are incorporated radially in the inside of the housing insert 7. In addition, the adapter 7 according to the Fig. 6, 7 or 8 upwardly open form pockets 53, in the corresponding projections (not shown in detail) of the mixing cartridge 9 project form-fitting manner. Both the abutment contour 49 and the form pockets 53 of the adapter 11 form a torque support, with the actuating forces are passed through the mixing cartridge 9 to the valve body 1 and thus the technique provided in the valve body 1 is held substantially free of force.

At the centrally arranged mixing water pipe 47, the mixed water line 19 is connected in a simple assembly technique, the sealing zone formed between the mixed water line 19 and the mixed water pipe 47 has a much lower compared to the prior art sealing diameter and therefore much cheaper in terms of the required sealing effort , According to FIG. 1, the sealing diameter is essentially identical to the inner diameter of the mixed water connection 47.

As is further apparent from Fig. 1, the guided to the water outlet opening 18 mixing water pipe 19 is constructed in several parts, with a deflecting insert 55 and a flexible water hose connected thereto 57. The deflecting insert 57 has, according to FIG. 2, an inlet-side flow channel 59 and an outlet-side flow channel 61, which are arranged approximately V-shaped to each other and converge at a lower bifurcation 63 (FIG. 2). The deflecting insert 55 is shown in FIG. 2 an upper bearing 65 and a lower bearing 67 coaxial with the housing axis A pivotally mounted. The upper bearing point 65 is carried out by a plug-in connection, in which the inlet-side channel portion 59 is inserted into the mixed water pipe 47 of the adapter 11, namely liquid-tight and pivotable. In contrast, the lower bearing point 67 is realized by a guide pin 74 which is integrally formed on the deflection insert 55 and which is inserted into a corresponding recess 69 in the insert bottom 31 of the housing insert 7.

On the outlet-side channel section 61 of the deflection insert 55, according to FIG. 1 or 2, the water hose 57 is inserted, which leads the mixed water as far as the water outlet opening 18 (FIG. 1). So that the water hose 57 is decoupled from all forces and moments that are caused by the pivoting movement, the deflection insert 55 additionally has a driver 71. The driver 71 protrudes in accordance with FIG. 4 in a housing groove 73, which is formed on the inside of the valve housing 1.

To limit the pivoting movement, a circumferential groove 75 (FIG. 2) is provided on the outer peripheral side on the housing insert 7. In the circumferential groove 75 projects in the transverse direction a stop screw 77, which is supported on the valve body 1. When assembling the valve, a preassembly unit can firstly be provided, in which the deflecting insert 55 with its lower guide pin 74 is first inserted into the recess 69 of the insert base 31 of the housing insert 7 in a process sequence. Subsequently, the adapter 7 with its mixed water pipe 47 is liquid-tightly placed on the upwardly projecting inlet-side channel portion 59 of the Umlenkeinsatzes 55, under the support of the adapter 11 on a radially inner annular shoulder 79 (Fig. 1) and with a free play of movement between the lower end faces the hot and cold water pipe 39, 41 of the adapter 11 in the not shown connection terminals of the insert base 31 of the housing insert 7. Subsequently, the mixing cartridge 9 is inserted into the housing insert 7. The pre-assembly unit thus formed is inserted into the upwardly open mounting space of the fitting housing 1 and screwed therein by means of the central clamping element 25 (FIG. 1). Subsequently, the water hose 57 is introduced via the water outlet opening 18 into the outlet-side channel section 61.

In order to facilitate this insertion process, in Fig. 1 or 2 at the passage 13 between the fitting housing 1 and the swivel spout 3, a plastic guide 81 (Fig. 2) is inserted. With the aid of the plastic guide 81, the water hose 57 is precentered during the insertion process, before it is inserted liquid-tightly into the outlet-side channel section 61 of the deflection insert 55.
