Description

13106~,2 Water Fitting, Particularly for Domestic Sanitary Installations I

Backaround of the Invention The present invention concerns a water fitting, particularly for domestic sanitary installations. The present invention particularly concerns such water fittings having a turbine wheel arranged in a flow duct and acted on by a flow of water to drive a sealed electrical generator.
Such a water fitting is, for example, known from the international patent application published under the number WO 85/01337. This reveals a water dispenser whose water flow can be switched on and off by means of an electrically controlled valve. A turbine wheel acted on by the water is located in the flow duct of the water dispenser upstream relative to the valve and this turbine wheel drives a low power electrical generator. The generator is connected to a control arrangement controlling the valve, it being possible to charge the accumulator of this arrangement with the electricity supplied by the generator. The circular cross-section flow duct of the water dispenser has a 90 degree bend, the turbine wheel being upstream of this bend and the axis of rotation of the turbine wheel coinciding with the longitudinal axis of the tubular casing bounding the flow duct in this region. The generator is aligned with the turbine and is located outside the casing in the reyion of the 90 degrees bend, an opening being provided in the casing for the passage of the generator shaft coupled to the driven shaft of the turbine wheel.

A hat-shaped sealing element protruding through the opening in the casing into the flow duct is clamped between the generator and the casing of the water fitting. This sealing element has a hole extending in the axial direction for the driven shaft of the turbine wheel or the drive shaft of the generator. Between the inner surface of the sealing element and the generator shaft, there is an O-ring seal which, further in the axial direction, is in contact with the inner end surface of the sealing element and, opposite this, with a sealing disc provided on the generator shaft. This sealing arrangement leads to substantial losses relative to the low power of the turbine. In addition, it is subject to wear and aging which can lead to water penetrating into the inner part of the generator.
The object of the present invention is therefore to produce a water fitting having a turbine driver generator whose losses are extremely small and whose generator is reliably sealed against the flow duct independent of aging.

Summary of the Invention This object is achieved by having a wall of non-magnetizable material separate the flow duct from the generator. Magnetic coupling means is provided for coupling the turbine wheel in the flow duct to the generation situated outside the wall of non-magnetizable material.
The water fitting has no mechanical connection between the turbine wheel and the generator. On the contrary, two coupling parts are provided, these being 1 3 1 06~2 separated from one another by the non-magnetizable partition and coupled to one another by means of a magnetic field penetrating the partition. There is, therefore, no further necessity for a dynamic seal which generates losses and is subject to aging.
Preferably, at least one of the coupling halves has a permanent magnet arrangement. On the other coupling part, an electro-magnetic arrangement or even quite simply a part in soft iron can be provided. This is then driven along by the magnetic field generated by the permanent magnet arrangement.
In a particularly preferred embodiment having good torque transmission properties in a small space and with simple constructi,on, both coupling halves include one permanent magnet.
Another particularly simple embodiment of the water fitting uses large disk-shaped coupling halves for transmitting particularly large torques.
The design of the water fitting preferably involves few parts. One embodiment permits the water to flow in a straight line through the water fitting.
Using the present invention, an electrical water fitting can be constructed which is independent of extraneous electrical energy.
The invention is now described in more detail by means of an illustrative example shown in the accompanying single figure.

Brief Description of the Drawina The figure is a sectional view of a water fitting in accordance with the present invention.

1 3 1 0~

-Desrip~Q~ of the ~refer~gL~mkQdimen~
The water fitting 10 has an essentially hollow cylindrical casing part 12, for e~ample brass, with an inlet connection 14 provided in one end region of the casing part 12 protruding towards the outside in the radial direction. The inlet connection end of the casing part 12 is closed by a thin-walled partition element 16 in a non-magnetizing material, for example brass or austentic stainless steel. At its end opposite to the casing part 12, the partition element 16 has a protruding hollow cylindrical tube part 18 which is aligned with the casing part 12 and into which is screwed a direct current generator 20.
A turbine wheel 24 whose rotational axis 26 coincides with the longitudinal axis of the substantially hollow-cylindrical casing part 12 is rotatably supported within the casing part 12, which bounds a flow duct 22 for the water supplied through the inlet connection 14.
A first coupling part 28, which is provided in the region of the partition element 16, is rotationally solidly connected to the turbine wheel 24. A second coupling part 30, which is rotationally solidly connected to the generator 20, is provided on the opposite side of the partition element 16 from the first coupling part 28.
The two coupling parts 28, 30 are magnetically coupled to one another, as is described in more detail below. The two connection terminals 32 of the generator 20 are v connected to a control arrangement 36, as is indicated by the dotted link 34, and this control arrangement 36 is in turn electrically connected by means of the connection 13106g2 lead 40, also shown dotted, to a valve 38, symbolically represented and connected downstream of the casing part 12 when viewed in the flow direction S. The control arrangement 36 has a storage element (preferably an accumulator) shown diagrammatically and indicated by 42.
This accumulator can be charged by the electricity supplied by the generator 20.
When the control arrangement 36 receives a signal, for example from a proximity sensor, the valve 38 is opened by means of the electricity stored in the storage element 42 so that the water commences to flow in the flow direction S. The turbine wheel 24, acted on by water flowing in the axial direction, begins to rotate, the rotation being tra~smitted through the partition element 16 to the generator 20 by means of the two coupling parts 28, 30. The storage element 42 is now charged by the electricity supplied by the generator 20.
As soon as the control arrangement 36 receives a signal for the interruption of the water flow, again for example from the proximity sensor, the valve 38 is closed so that the turbine wheel 24, and hence also the generator 20, come to rest.
The turbine wheel 24 and the first coupling part 28 are seated rotationally solidly on a common shaft 44 which is rotatably supported at one end on the partition element 16 in the region of the first coupling part 28 and, at the other end, on a support partition 46 located within the casing part 12. For this purpose, the partition wall 48 of the partition element 16, which closes off the flow duct 22, has, in its central region, 1 3 1 06~2 a bearing sleeve 50 protruding within the casing part 12, the longitudinal axis of this bearing sleeve coinciding with the axis of rotation 26 of the turbine wheel 24. A
bearing ball 52 is provided in the bearing sleeve 50 and the end of the shaft 44 protruding into this bearing sleeve 50 supports itself on it in the axial direction.
The support partition 46 has a blind hole 54 open towards the turbine wheel 24 and its a~is coincides with the axis of rotation 26. A hat-shaped plastic bearing bush 56 is inserted into the blind hole 54 and in it, there is a further bearing ball 52 on which the other end of the shaft 32 supports itself axially. This end region of the shaft 44 is supported in the radial direction by the bearing sleeve 56. A carbide plate 58, shown dotted, can be provided on the inner end face of the bearing bush 56 so that axial forces can be accepted without dif~iculty.
In order to avoid hindrance to the flow of water, a plurality of holes 60 extending in the axial direction is provided in the support partition 46. These holes are arranged in a circle around the axis of rotation 26.
In the region of the partition wall 48, the first coupling part 28 is designed to be disc-shaped and encloses, at a slight distance, the bearing sleeve 50.
In this region, an annular permanent magnet 62, which is laterally magnetized on its end surface facing towards the partition wall 48, is inserted in the first col~pling part 28. In the region of the inlet connection 14, the first coupling part 28 has a reduction in diameter which merges into a cylindrical part 64 which is followed by the turbine wheel 24. The reduction in diameter 131~6~2 mentioned deflects the water supplied in the radial direction through the inlet connection 14 into the flow direction S which extends in the axial direction.
The turbine wheel 24 has a substantially cylindrical turbine body 66 which has the same diameter as the cylindrical part 64 of the first coupling part 28. Turbine blades 68, which are acted on by water flowing in the axial direction, protrude outwards from the turbine body 66 in the radial direction.
The second coupling part 30 seated on the rotor shaft 70 of the generator is also designed disc-shaped, and end surface facing towards the partition wall 48 extending parallel to it. The second coupling part also has a follow-cylindral.permanent magnet 62 which is also laterally magnetized on its end surface facing towards the partition wall 48. Such permanent magnets 62 are generally known and can be obtained, for example, from the Philips Company under the name "FERROXDURE".
The generator 20 is a direct current micromotor, Faulhaber system, operated as a generator. Such units are manufactured and sold, for example, by MINIMOTOR SA, Agno, Switzerland. A commutator plate 72, which carries a cylindrical, obliquely wound rotor coil 74, is seated on the rotor shaft 70. Within the rotor coil 74, there is a fixed location exciter magnet 76 which can be magnetized on its periphery, its magnetic field penetrating the rotor coil 74 and the magnetic circuit being completed by a hollow cylindrical soft iron sleeve 78. On its side facing towards the partition element 16, the soft iron sleeve 78 is connected to a 1 3 1 06~2 retention flange 79 which is screwed into the tube part 18 and on which the rotor shaft 70 is supported. A
plastic cover, on which the rotor shaft 70 is also rotatably supported and which holds the brushes 82, is inserted as a spigot into the other end of the soft iron sleeve 78. The brushes 82 are electrically connected to the connection terminals 32. Any suitable motor or generator can, of course, be used instead of the direct current micromotor shGwn and described here. Apart from very high efficiency, the generator 20 proposed exhibits an extremely low moment of inertia, which leads to particularly good starting properties and hence to the generation of electricity even in the case of small water flow velocities.
In order to avoid having to deflect the water, it is also conceivable that the first coupling part should be formed on the turbine wheel itself. It would then be possible to have an annular permanent magnet surrounding the turbine blades in the peripheral direction. The second coupling part could, in this case, be located coaxially around the casing and, for example, supported ratably on it, the casing then consisting of a non-magnetizing material at least in the region of the two coupling parts. The rotational motion of the turbine wheel would then be transmitted to the second coupling part through the casing wall, this rotational motion being then transmitted, for example, by means of a gear from the second coupling part to a generator.
The water fitting, which is independent of an extraneous electrical energy source, can have a plurality of valves controlled by the control arrangement.

1 3 1 ~ 2 g Temperature measurement probes or displays, for temperature for example, can also be provided, however, and these are all supplied from the storage element charged by the generator. It is, in particular, also conceivable that the water fitting should therefore be designed as a mixing fitting and have an adjustable valve for the hot water and an adjustable valve for the cold water. The flow quantity of the water concerned would be controlled as a function of the mixed water temperature measured by means of a temperature sensor. The turbine wheel is then driven either by mixed water, cold water or hot water.
Other permanent magnets, for example rod-shaped, can of course be provi~ed instead of the annular permanent magnets 62 on the coupling parts 28, and 30.
Additional variations and modifications exist which are within the scope and spirit of the invention as described and as defined in the following claims.
