Valve for a water discharge nozzle

The invention relates to a Water discharge with a connecting line, especially one in a Elbows slidably guided tubing to a Mixing and / or shut-off valve and with various Water jet formers, wherein a by an actuator adjustable switching valve alternatively a Wasserauslaßmundstück or shower jet formers is pressurized water supplied.

Such Water discharge was from the publications US-A-5,145,114 and DE 33 06 947 A1 and DE 195 27 232 A1 already known. Here, the conversion of Water discharge occurs different spray face with a Slide, the actual outside the handle arranged or with one hand at the extended Position is hardly to use.

The invention is based on the task in the preamble of claim 1 specified Water discharge fitting to improve, and in particular the handling and to optimize the switchover.

This object is achieved in that as an actuator, a lever is provided which is connected an end portion of an upstream of the Wasserauslaßmundstück disposed valve member of the change-over valve and also connected with a rotation axis is mounted on a housing part, wherein a portion the lever of a rectangle surrounding the Water discharge Housing projects as actuation grip and the housing dimensioned with the operating handle in cross-section so is that it umfaßbar by the user with one hand is. Further embodiments of the invention are defined in claims 2-17 specified.

For simplicity, in the embodiments in the drawing, identical or corresponding elements each provided with the same reference numerals. The Water discharge fitting shown in Figs. 1 to 12 of the drawing is arranged in a housing 1 and via a hose line 61, which in a tube sheet 60 is axially movable, supplied with compressed water. The pipe bend 60 is at its other end region rotatably supported on a mixing and shut-off valve 6, wherein the mixing and shut-off valve 6 at a is sink 7 attached with a sink 70th The Hose 61 is in this case by the mixing and shut-off valve 6 passed and under the washbasin 7 (not shown in the drawing) with the outflow port the mixing and shut-off valve 6. With an actuating lever 63 on the mixing and shut-off valve 6 may in a known manner in a first degree of freedom the mixing ratio of the inflowing cold and Hot water and in a second degree of freedom the totalization the water can be adjusted.

In the housing 1 a bottom plate 3 is provided with a supply pipe 31 are arranged, wherein the supply pipe 31 upstream is led out of the housing 1 and a Thread 310 for a nut 62 for connection the tubing 61 has. Downstream the tubing 61 is in a thickened area the supply pipe 31, a return valve 33, with an invalid return suction of water is prevented. The supply pipe 31 is at an angle 312 arranged approximately 60 ° inclined to the bottom plate. 3 At the outer edge of the bottom plate 3, a bearing 30 arranged, on which a bow-shaped, made of plastic in Injection molding manufactured lever 4 with a first Leg 40 is rotatably hinged, while a second leg 41 connected to a switching valve 2 is. The two legs 40,41 are a Apex 42 interconnected. At the end the leg 40 are formed two bearing pins 43, as can be seen especially from FIG. 2 and 10. The trunnion 43 can have a radial slot 300 be disseminated radially in the bearing 30 so that the Lever 4 is pivotable about the camp 30th In the housing 1 is a breakthrough 10 formed from which the leg 40 projects with the apex 42nd Of the Opening 10 is in this case with a correspondingly projecting Diaphragm 11 of elastomeric material so closed that upon actuation of the lever 4, the diaphragm 11 is deformed accordingly. Of the Leg 40 is designed in the form of a deduction faucet, so that when gripping the housing 1 of the Lever 4 is easily operable.

To the bottom plate 3, the switching valve 2 is provided with a Valve member 20 is fixed by means of three snap-lugs 220th The snap-lugs 220 are secured to an enclosure 22 is formed, which is concentric with the valve member 20 sealed with a rod 200 leads. In the Detent position of the snap tabs 20 engages socket 221 the housing 22 in an opening 311 of the supply pipe 31 sealed one, of which the inflowing water in the Housing is inserted into a central region in which it in dependence on the position of the valve member 20 either a 51 or concentrically Wasserauslaßmundstück arranged around the Wasserauslaßmundstück 51 Shower jet formers 52 is passed. The rod 200 the valve member 20 is carried out of the housing 22 the bottom plate 3 composed passed and contributes at the outer end a constriction 201. This constriction 201 is the arm 41 like a fork with bent arranged claws inserted 410, wherein cylindrical Sliding surfaces 411 of the claws 410 to the End sides of the constriction 201 lie. between a Face of the claw 410 and a receptacle 32 in the bottom plate 3 is arranged a spring 21, with the the valve member 20 in a preferred Ausflußstellung, as shown in Fig. 2 of the drawing, is pressed becomes. Coaxially to the valve member 20 is attached to housing 22, a threaded sleeve 223 is formed, on which a mounted terminal body 5 with a threaded extension 50 is. In the terminal body 5 is centrally the Wasserauslaßmundstück 51 and concentric thereto are in two The rows Brausestrahlbildner 52. On the Sealing body 5 is a sleeve-shaped outer collar 53 arranged on the one hand to the terminal body 5 and on the other hand sealed to the housing 22 with sealing rings is such that between the housing 22 and the terminal body 5, an annular channel 224 is formed over the supplied single Brausestrahlbildner 52 with water will. For this purpose, above the valve member 20 in the housing 22 slots 225 for the overflow of inflowing water formed. The valve member 20 is between two opposing annular Valve seats 226 and 227 axially displaceable in the housing 22, said the incoming water pressure flows laterally between the two valve seats 226,227. To introduce the valve member 20 in the housing 22 is a valve seat 227 as a detachable sleeve formed in the housing 22nd The housing 1 is designed such that it is in The flow direction of the water steadily increases in cross-section, wherein the initial cross-section slightly larger than the pipe diameter of the pipe bend 60, while the downstream end portion of the outer periphery the termination body 5 encloses. Here, the housing 1 about the same curvature as the tube sheet 61 on, the lever 4,40 on the inner arc side of the arcuate housing 1 protrudes. To support the Housing 1 on the switching valve 2, this is a Rib 13 which one of the plug-in location on Annular collar 530 of the outer collar 53 rests. to further Securing in the inserted position, the housing 1 at the upstream lying end portion of the nut 62 pressed against the collar 530th

The Water discharge fitting described above has the following function: In the position described in FIG. 1 of the drawing the housing 2 is attached directly to the tube sheet 60, the nut 62 is engaged with the tube Water discharge fitting and the position of the Elbows 60 determined. In this position, constitutes the Water discharge fitting with the pipe bend a stationary pivotable Wasserauslaufarm the mixing and shut-off valve 6. In this position, the spring 21 presses the valve member 20 against the valve seat 226, so that the inflowing water centrally the Wasserauslaßmundstück 51 is supplied, in which produces a bundled water jet discharged and directed into the sink 70 becomes. however, a mobile water sprayer If needed, it can the user grip the housing 1 and the Water discharge fitting with the tubing 61 from the pipe bend 60 Pull out. If this instead of a single beam a plurality of spray jets are required, may be replaced at a force introduction on the discharge cock like formed membrane 11 accomplished, whereby the lever 4 is displaced by, so that against the force of the spring 21, the valve member 20 moves to the valve seat 227, and now the water outlet through the slots 225 into the annular channel 224 and released to the individual beam formers 52 , while the access to the Wasserauslaßmundstück 51 is shut off. Will not spray jets requires more, for a reduction of force application in the lever 4, the valve member 20 from the Spring 21 is again fed back to the valve seat 226 - in the position of FIG. 2 -and the waterway to Wasserauslaßmundstück 51 released again. The periphery of the housing 2 is in this case dimensioned such that a user can comprise the well casing 1, wherein Suitably, the length of the housing 1 about twice Diameter of the final body 5 corresponds.

The embodiment shown in Fig. 13 differs to the above-described substantially characterized in that the housing 1 with a rubber-elastic Coating 12 is provided, wherein the membrane 11 is integrally formed with the coating 12th By the elastomeric coating 12 can grip and manageability of Water discharge significantly increase.
