Valve for a water discharge nozzle

DESCRIPTION

Water outlet tap.

The invention relates to a water outlet tap with a connection duct, especially a flexible guided pipe so that it can be moved in a tube bend, towards a mixing and / or closing valve, as well as with various jet producers of water, in which with an inverting valve adjustable by means of an actuating element, pressurized water can optionally be fed to a water outlet or to jet or nozzle producers.

A water outlet tap of this type was already known from publications DE 33 06 947 A1 and DE 195 27 232 A1. In them, the inversion of the water outlet tap to different jet producers is carried out with a slide, which was arranged outside the handle itself or which, in the extracted position, cannot be operated with one hand.

The invention has the mission of improving the water outlet tap indicated in the general concept of claim 1 and in particular of optimizing ease of handling and investment possibilities.

This problem is solved according to the invention, thanks to the fact that as a drive element a lever was provided, which was connected with one end to a member of the reversing valve arranged, upstream, before the water outlet and also it was housed with a pivot shaft in a housing part, protruding a part of the lever, as a control handle, of a housing that envelops the water outlet tap and the housing being with the control handle sized in cross section so that it can be encompassed by the user with one hand.

Other configurations of the invention are indicated in claims 2 to 17.

For clarity, the same or analog elements have been provided in the drawings of the examples of realization of equal reference numbers.

The water outlet tap shown in Figures 1 to 12 is disposed in a housing 1, and is fed with pressurized water through a flexible pipe 61 arranged so that it can move axially in a tube bend 60. The bend of tube 60 was rotatably held at its other end in a mixing and closing valve 6, fixed to a table 7 with a sink 70. The flexible pipe 61 passes through the mixing and closing valve 6 and extends under the table 7, (not shown in the drawings), to the outlet opening of the mixing and closing valve 6. With a lever adjustment 63 provided in the mixing and closing valve 6, the mixing ratio of the cold and hot tributary water can be adjusted in a first degree of freedom and, in a second degree of freedom, the total water flow.

A base plate 3 with a feed tube 31 is disposed in the housing 1, which has been driven upstream out of the housing 1 and has a thread 310 for a union nut 62 that splices the flexible pipe 61. Current downstream of the pipe Flexible 61 is disposed, in a thickened air of the feed tube 31, a reflux inhibitor 33 that prevents an unacceptable backsliding of water. The feed tube 31 is inclined in relation to the base plate 3 an angle 312 of approximately 60^°.On the outer edge of the base plate 3, a bearing 30 was arranged, in which a stirrup-shaped lever 4 manufactured in a plastically injected casting process was pivotally articulated with a first arm 40, while a second arm 41 was attached to a reversal valve 2. The two arms 40, 41 are joined in the vortex 42. At the end of the arm 40 two worlds 43 are formed, as can be seen especially in Figures 2 and 10. The munons 43 can fit radially into the bearing 30 through a radial groove 300, so that the lever 4 can swing around the bearing 30. In the housing 1 there is a gap 10 from which the arm 40 protrudes with the vortex 42. The gap

ES 1 041 925 U is closed with an elastic rubber membrane 11, so that when the lever is operated the membrane deforms accordingly. The arm 40 is configured in the form of a trigger, so that by gripping the housing 1, the lever 4 can be operated comfortably.

On the base plate 3, the inversion valve 2 is fixed with a valve member 20, with the help of three elastic-fit heels 220. The heels 220 are configured in a housing 22, which concentrically and hermetically glides the valve member 20 with a 200 bar. In the interlocking position of the elastic lace heels 20, a tube 221 of the housing 22 fits tightly in an opening 311 of the feeding tube 31, from which the tributary water is introduced into the central part of the housing, in which is conducted, depending on the position of the valve member 20, either to a water outlet 51 or to jet producers or nozzles 52 arranged concentrically around the water outlet 51. The bar 200 of the valve member 20 hermetically exits the housing 22 through the base plate 3, and carries a throttle 201 at the outer end. In said throttle 201 the arm 41 is inserted with bent jaws 410 arranged at fork mode, supporting cylindrical sliding surfaces 411 of the claws 410 on the front sides of the choke 201. Between a front side of the claws 410 and a housing 32 located on the base plate 3, a spring 21 is disposed with which the valve member 20 is pushed to a preferred outlet position, as shown in Figure 2. In the housing 22 is formed, coaxially with the valve member 20, a threaded tube 223 in which a closure component 5 with a threaded boss 50 is fixed. In the closing component 5, the water outlet 51 is arranged in the center and, concentrically thereto, two rows of jet producers or nozzles 52. An outer collar 53 in the form of a bushing is arranged on the closure component 5, which is sealed with sealing rings on the one hand in relation to the closing component 5 and on the other hand in relation to the housing 22, so that between the housing 22 and the closure component an annular channel 224 is formed through which water is fed to the individual jet producers or nozzles 52. To this end on top of the valve member 20, in the housing 22, there are slots 225 for the effluent water spill. The valve member 20 is disposed between two annular and opposite valve seats 226 and 227, so that it can move axially in the housing 22, the tributary water entering laterally between the two valve seats 226, 227. One of the valve seats 227 is configured as a removable bushing in the housing 22 to introduce the valve member 20 into the latter.

The housing 1 is configured so that it widens continuously in the cross-section in the direction of water flow, the initial cross-section being slightly larger than the diameter of the tube elbow 60, while the downstream end encompasses the outer contour of the closure component 5. The housing 1 has approximately the same curvature as the tube elbow 61, the lever 4, 40 protruding from the inside of the arc of the curved housing 1. To hold the housing 1 on the reversal valve 2, it is provided with a rib 13 which, in the fitted position, rests on an annular flange 530 of the outer collar 53. For greater assurance in the fitted position, the union nut 62 pushes the housing 1 at the end upstream against the flange 530.

The water outlet tap described above works as follows:

In the position shown in Figure 1, the housing is housed directly in the tube elbow 60, the union nut 62 intervening in the tube and thus determining the position of the water outlet tap with respect to the tube elbow 60. In this position, the water outlet tap constitutes a stationary tiltable water outlet arm of the mixing and closing valve 6 with the tube elbow. In this position, the spring 21 pushes the valve member 20 against the valve seat 226, so that the tributary water is fed through the center to the water outlet 51, in which a water jet is produced in make it discharge oriented in the sink 70.

If, on the contrary, a mobile water outlet is required, the user grabs the housing 1 and removes the water outlet tap with the flexible pipe 61 of the tube elbow 60. If several jets are required instead of a Uranic jet, these can be achieved by applying force on the membrane 11 configured as a trigger, whereby the lever 4 is correspondingly deviated, so that the valve member 20 moves on the seat of valve 227 against the force of the spring 21, thus unblocking the water outlet through the grooves 225 to the annular channel 224 and to the individual nozzles 52, while the access to the water outlet nozzle 51 is closed. If the nozzle jets are no longer necessary, the force applied on the lever 4 is reduced, thereby causing the spring 21 to return the valve member 20 again to the valve seat 226, to the position of figure 2, the water path to the water outlet 51 being unlocked again.

The perimeter of the housing 22 will be sized so that the user can grasp the housing 1 well, the length of the housing 1 conveniently corresponding to approximately twice the diameter of the closure component 5.

The exemplary embodiment shown in Figure 13 differs from that described above essentially in that the housing 1 is provided with an elastic rubber coating 12, the membrane 11 being configured in one piece with the coating 12. With the elastic rubber coating 12 the grip and ease of handling of the water outlet tap is greatly increased.
