  • A first embodiment of a sanitary fitting 10 according to the invention is shown in FIG Fig. 1 . 2 and 4 shown.
  • As Fig. 1 shows, the sanitary fitting 10 a fitting housing 12, from which a mounting socket 14 protrudes downwards. This is intended to be the Sanitary fitting 10 to attach to a mounting surface, not shown, a washstand by means of a nut 14 '. The fitting housing 12 has a recess with a mixing cartridge 15 used in a known manner therein with actuating element 16 for controlling the flow of water. From the fitting housing 12 is in the vertical direction from a pivotable about a vertical axis guide tube 18 from. from the fitting housing 12 forth, the guide tube 18 tapers bell-like to a diameter D and initially runs straight and then almost in a semicircular arc. A free end portion 20 of the guide tube 18 widens bell-like and steady. The interior of the free end region 20 forms a receptacle 22 for a removable and reusable water spill head 24.
  • The Wasserausflusskopf 24 is firmly connected to a through the interior of the guide tube 18, the fitting housing 12 and the mounting sleeve 14 extending through Ausziehschlauch 26. The Ausziehschlauch 26 runs as generally known in a loop back to the fitting housing 12. The Ausziehschlauch 26 has (see Fig. 2 ) has an outer jacket tube 86 and a water hose 28 disposed inside the jacket tube 86. Between the jacket tube 86 and the water hose 28, an electrical line 84, preferably a multi-core stranded wire, is arranged. The water hose 28 is intended to guide mixed water from the mixing cartridge 15 to the water outflow head 24. The mixing cartridge 15 is also connected in a known manner with not shown cold and hot water supply line.
  • As in the Fig. 1 . 2 and 4 shown has a housing 36th the Wasserausflusskopfs 24 on a bell-like shape, which is adapted to the shape of the receptacle 22. In order to allow easy handling, the housing 36 has a pin-like extraction aid 38, which projects in the radial direction. The free end portion 20 of the guide tube 18 has for this purpose (see Fig. 4 ) at the end of the guide tube 18 open guide slot 40 through which the extension aid 38 is guided during retraction and extension of the Wasserausflusskopfs 24. The housing 36 further includes a bead 42 which, if the Wasserausflusskopf 24 is inserted into the receptacle 22 engages in the guide slot 40. Except in the region of the bead 42 and an upstream end portion 44, the housing 36 is thin-walled, formed with a substantially constant wall thickness. At the downstream end-except in the region of the bead 42-the housing 36 has a circumferential housing end face 46, wherein the bead 42 projects beyond the housing end face 46 in the flow direction.
  • The Wasserausflusskopf 24 has a water-conducting, rotationally symmetrical, translucent, light-conducting and connected to the water hose 28 spout 50. The spout 50 is made of, for example, acrylic glass or other transparent or translucent material. The spout 50 has a hollow cylindrical light transmission area 52 in a downstream portion. This light transmission region 52 is bounded on the one hand, upstream of a coupling surface 56 and on the other hand, at the downstream end of the light transmission region 52 and at the same time of the outflow tube 50 from an exposed end face 58. The end face 58 is in the outflow direction of Einkopplungsfläche 56 and the end face 58 as well as the coupling surface 56 are perpendicular to the axis of rotation of the outflow pipe 50th
  • The outflow pipe 50 has, spaced from the end face 58, a radially outer, upstream aligned shoulder 60, which bears against the housing end face 46 when the discharge pipe 50 is inserted into the housing 36. Between the shoulder 60 and the end face 58, the outflow tube 50 has an exposed lateral surface 72, wherein the exposed lateral surface 72 continuously merges continuously into an outer surface of the housing 36. The exposed lateral surface 72 is also exposed when inserted into the receptacle 22 Wasserausflusskopf 24.
  • Adjacent to the light transmission region 52, the outflow tube 50 has a connection area 64 in the vicinity of the nozzle, wherein the outflow tube 50 tapers in the transition region from the light transmission region 52 to the connection region 64.
  • An inner diameter of the outflow tube tapers in two stages from the larger inner diameter of the light transmission region 52 to the smaller inner diameter of the connection region 64, wherein the inner diameter is selected such that a jet regulator 110 described below can be inserted into the outflow tube 50.
  • A light source 70 is arranged directly adjacent to the coupling surface 56 of the outflow pipe 50. The coupled at the coupling surface 56 light of the light source 70 is transmitted through the light transmission region 52 to the end face 58 and at least this partially decoupled from the spout 50. The light is also coupled out of the outflow tube 50 in the area of the exposed lateral surface 72 between the shoulder 60 and the end face 58, except in the region of the bead 42.
  • As a light source 70, a plurality of, preferably nine light-emitting diodes (LED) 74 are used, wherein the diodes 74 are arranged in the circumferential direction at regular intervals and a light cone axis of each diode 74 at least approximately at right angles through the coupling surface 56 and parallel to the axis of rotation of the spout 50 extends , The alignment of the light cone axes ensures that the largest possible proportion of the light emitted by the diodes 74 exits through the end face 58 and through the lateral surface 72. In addition to white light, the light source 70 can also emit colored light.
  • The diodes 74 are arranged on an annular printed circuit board 76, which surrounds the outflow pipe 50 in the connection region 64. On a further, electrically connected to the annular printed circuit board 76 printed circuit board 78, a control circuit for the light source 70 is arranged with a switching element 80. The further printed circuit board 78 is fastened to the connecting region 64 of the outflow tube 50 and in the flow direction above the annular printed circuit board 76. The switching element 80 is a button 80 'with probe 82, wherein the probe 82 penetrates the bead 42 of the housing 36 in the flow direction below the pull-out aid 38 tight. By means of the button 80 ', the light source 70 can be controlled depending on the configuration of the switching electronics on the other printed circuit board 78. It is conceivable the pushbutton 80 'switches on the light source 70 during a first actuation and switches it off again in a further actuation, wherein the switch-off can be performed with a time delay. Another possibility is that the light source 70 is turned off by a timer after a certain period of time.
  • The supply of electric power to the electrical circuit and the light source 70 is ensured via the electrical lead 84, which is electrically connected to a power supply. The power supply is preferably mounted in a separate box below the washstand and is adapted to be applied in the wet area. As power source for the power supply, a power supply unit is used, and instead of the power supply, batteries or accumulators can be used.
  • In order to produce a tight and at the same time firm connection of the extension hose 26 with water hose 28 and the water outlet head 24 with outflow pipe 50, the inner water hose 28 projects beyond the outer jacket hose 86. In the water hose 28, a clamping pin 92 is inserted from the free end, so that the water hose 18 between the clamping pin 92 and the sleeve 90 is firmly and sealingly clamped. The clamping pin 92 has a flow channel, the diameter of which substantially equals the diameter of the unstretched water hose 28. A length of the clamping pin 92 is selected such that the clamping pin 92 can be inserted only in the region of the water hose 28, which projects beyond the jacket tube 86, so that the clamping pin 92 in Flow direction of the jacket tube 86 is spaced. As a result, it is possible to guide the electrical line 84 arranged between the jacket hose 86 and the water hose 28 through a through opening 94 of the sleeve 90 to the further printed circuit board 78 without pinching the electrical line 84 between the jacket hose 86 and the clamping pin 92.
  • The sleeve 90 has an external thread and is threaded into the connection region 64 of the outflow tube 50. In order to produce a sealed connection between the clamping pin 92 and the outflow pipe 50, the clamping pin 92 has a circular ring surface lying at right angles to the outflow direction and the connecting region 64 has a contact surface which also faces this annular surface and is likewise annular. Between the annular surface and the contact surface a sealing ring 96 is clamped. Adjacent to the contact surface, the connection region is water-conducting and has an inner diameter which is substantially equal to the inner diameter of the clamping pin 92.
  • The housing 36 is in a region in which the Ausziehschlauch 26 enters the wasserausflusskopf 24 and in a region in which the housing 36 abuts the light transmission region 52 of the spout 50 is sealed to the Ausziehschlauch 26 and with the spout 50, whereby a Connection of the housing 36 with the spout 50 or with the jacket tube 86 is made and neither dirt nor moisture can penetrate into the interior of the Wasserausflusskopfs 24.
  • Into the spout 50 is from the downstream end fro an external thread 98 having Strahlregler 110 screwed. The jet exciter 110 has a cylindrical shape, has a shape that fits into the outflow tube, and is completely sunk into the outflow tube 50 in the flow direction. A downstream, crown-like plug-in area 112 is formed by recesses 114 and elevations 114 ', which are arranged regularly in the circumferential direction and oriented in the direction of flow. In the flow direction, an O-ring 116 for sealing the jet regulator 110 with respect to the outflow pipe 50 is arranged on the jet regulator 110 between the external thread 98 and the plug-in region 112. As a jet regulator 110, a Niberl aerator can be used.
  • The crown-like mating portion 112 allows easy replacement of the jet regulator 110 by a new jet of the same type. To replace the jet regulator 110, the new jet regulator is plugged onto the plug-in region 112 of the jet regulator 110 installed in the outflow tube 50. By means of the new jet regulator, the jet regulator 110 screwed into the outflow pipe 50 can be unscrewed. The new jet regulator is screwed in analogously. The crown-like plug-in region 112 makes it possible to dispense with special tools for exchanging the jet regulator 110.
  • In a further embodiment of the first embodiment, the housing 36 is made of a plastic instead of metal. The probe 82 of the button 80 'can, as in Fig. 2 shown to be guided tightly through the housing 36 or be spanned with a membrane. The membrane may be, for example, by means of a well-known two-component injection process be molded onto the plastic housing.
  • Another embodiment of a Wasserausflusskopfs is in Fig. 3 shown below, with only differences to the above-described Wasserausflusskopf will be discussed below. The same reference numerals are used for corresponding elements.
  • The switching element 80 is integrated in the pull-out aid 38. For this purpose, the pull-out aid 38 has a recess extending in the axial direction of the pull-out aid, open to the outside, into which the switching element 80 is inserted. From a bottom of the recess, a duct 120 leads into the interior of the Wasserausflusskopfes 24. The switching element 80 in the form of a button 80 'has a projecting out of the recess probe 82, which is completely encompassed in the circumferential direction of a protective cap 122. The protective cap 122 is screwed onto the pull-out aid 38 and is preferably rubber-elastic. Between the protective cap 122 and the switching element 80, a fitting against the inner circumferential surface of the recess sealing ring 124 is arranged.
  • The guided through the Ausziehschlauch 24 electrical line 84 is electrically connected to the light source 70 carrying the printed circuit board 76. The printed circuit board 76, which is clamped in a well-known manner, also carries the switching electronics. The switching element 80 is connected via a guided through the duct 120 electrical switching line 126 to the printed circuit board 76.
  • The housing 36 of the Wasserausflusskopf 24 is formed except thin in the region of the bead 42. The in the Guide slot 40 engaging bead terminates in the longitudinal direction of the housing 36 at the same height as the housing 36, so that the bead 42 does not project beyond the housing end face 46 and the spout 50 has a circumferential, exposed lateral surface 72.
  • In the upstream end region 44, the housing 36 has a plurality of radial passages 128 arranged uniformly in the circumferential direction. A cavity located radially between the outflow tube 50 and the sleeve 90 and the housing 36 and longitudinally between the passageways 128 and the coupling surface 56 is filled with a filling compound, for example a two-component casting resin, which passes through the passageways into the cavity is filled.
  • In a further embodiment, the actuating element 16 of the mixing cartridge 15 is operatively connected to a switching element arranged in the fitting housing 12, so that the light source is switched on when the water flows out.
  • In a further embodiment of the first embodiment, an electronically controlled valve is used instead of the mixing cartridge with actuator for manually controlling the flow of water through the sanitary fitting 10. The valve is connected via a control line of the multicore electric line 84 to the electrical circuit in the water outflow head 24. By actuating the switching element 80, the light source 70 in the Wasserausflusskopf 24 and on the other hand, the electrically controlled valve is controlled on the one hand.
  • In a further embodiment of the first Embodiment is the end face 58, not perpendicular to the outflow direction. The end face may be angled to the outflow direction, may be a curved surface or have almost any shape, whereby a light failure from the spout 50 can be influenced almost arbitrarily. The exposed lateral surface can also be changed in its optical property, for example by roughening the surface, whereby the exiting light is scattered more strongly, or by coloring the lateral surface.
  • In a further embodiment of the first embodiment, the printed circuit board 76 has a larger outer diameter, so that the printed circuit board 76 rests against the housing 36.
  • A second embodiment will be described with reference to FIGS Fig. 5 and 6 described.
  • As Fig. 5 shows, a hollow cylindrical fitting housing 12 is aligned vertically with a circular cross section of a sanitary fitting 10 according to the invention. The sanitary fitting 10 is intended to be mounted on a mounting surface of a vanity by means of a downwardly projecting mounting spindle 154 in a known manner. Inside the fitting housing 12 is a (see Fig. 6 ) Housing inner body 156 is arranged, which rests in the radial direction on the fitting housing 12. Down from two connecting lines 142, 142 'from the housing inner body 156, which are intended to supply hot and cold water to the sanitary fitting 10. In the fitting housing 12 is from above a Mixing cartridge 144 used with an above the fitting housing 12 arranged actuator 16 in a known manner.
  • In the fitting housing 12, a circular cylindrical outflow pipe 50 is inserted, so that the cylinder axis of the fitting housing 12 with the cylinder axis of the spout 50 includes an angle of 55 degrees and the spout 50 projects downwardly inclined from the fitting housing. The outer diameter of the outflow pipe 50 is smaller than the outer diameter of the fitting housing 12.
  • The spout 50 is made of a translucent material, the material having transparent and / or translucent properties. For example, the spout 50 may be made of glass or acrylic glass. The surface of the tube is smooth, but may also be rough, which may affect optical properties of the outflow tube 50.
  • As in Fig. 5 and 6 As shown, the spout 50 has an end face 58 at a downstream end and an entrance surface 56 at an upstream end, opposite the end face 58. An inner diameter I of the outflow pipe 50 is constant except in a mounting area which adjoins the coupling surface 56 and lies within the fitting housing 12. The mounting area has a larger inner diameter than the inner diameter I. In the mounting area, a threaded sleeve 146 having an internal thread is inserted into the outflow pipe 50, preferably glued. In the flow direction below the mounting area is the Outflow pipe 50 water leading. In the threaded sleeve 146, a threaded bush 150 is screwed, which protrudes from the spout 50 at the coupling surface 56. The threaded bushing 150 is encompassed by a U-shaped retaining ring 152, whose opening is aligned in the direction of the coupling surface 56 and in which an annular printed circuit board 76 is arranged. The annular printed circuit board 76 carries a light source 70, which consists of a plurality of light emitting diodes (LED) 74, preferably manufactured as surface mount devices (SMD). The diodes 74 abut the input surface 56 of the spout 50 such that the light cone axis of each diode 74 is perpendicular through the input surface 56 and the end surface 58 and parallel to the cylinder axis of the spout 50. The diodes 74 are circumferentially mounted at regular intervals on the printed circuit board 76. Of course, differently shaped light sources 70 may be used instead of the diodes 74.
  • The introduced from the diodes 74 in the spout 50 light is guided by this to the end face 58 and to a radially outer, lying outside the fitting housing 12 lateral surface 72 of the spout 50 and coupled out at the end face 58 as well as the exposed lateral surface 72 from this.
  • In the flow direction above the retaining ring 152, the threaded sleeve has an external thread.
  • The fitting housing 12 has a recess through which the spout 50 is guided. The housing inner body 156 has a circular cylindrical, Stepped blind hole for receiving the spout 50, wherein the blind hole adjacent to the fitting housing 12 has a larger the outer diameter of the spout 50 corresponding inner diameter and spaced from the fitting housing 12 has a smaller inner diameter. The area of the blind hole with the larger inner diameter is designed such that the outflow pipe 50 and the retaining ring 152 can be set in this area. The blind hole has an internal thread in the region of the smaller diameter, into which the threaded bushing 150 is screwed.
  • A mixed water channel 158 coming from the mixing cartridge 144, which leads mixed water from the mixing cartridge 144 to the outflow pipe 50, opens into a bottom region 160 of the blind hole.
  • The threaded bush 150 is screwed into abutment against the bottom region 160 in the housing inner body 156. The threaded bush 150 has, radially inwardly, a stop surface facing the bottom region 160, against which a jet regulator 110 rests. Between the jet regulator 110 and the bottom portion 160, a sealing ring 162 is clamped. This forms a transition from the mixed water channel 158 to the threaded bush 150 with inserted in this jet regulator 110 tight, so that outflowing water can not reach a radially outer side of the threaded bushing 150 and the spout 50.
  • In order to guide a multicore electric line 84 through the housing inner body 156 to the printed circuit board 76 with the light source 70 arranged thereon, the housing inner body 156 has a duct 164 which is in the blind hole, in a region in which the retaining ring 152 is disposed, opens. Adjacent to the duct 164, the retaining ring 152 has a radially aligned passage opening 166, so that the electrical line 84 can be passed through the duct 164 and through the passage opening 166. The electrical line 84 is electrically connected on the one hand to the printed circuit board 152 arranged in the retaining ring 152 and on the other hand to a switching electronics which is controlled by a switching element 80.
  • The switching element 80 is, as in Fig. 5 shown, a well-known switching element for a room lighting. By means of the switching element 80, a power supply to the switching electronics is turned on or off. The switching electronics is preferably mounted in a box 170 below the washstand due to the very slim design. In the box 170, for example, a transformer can be arranged, whose power supply can be switched on or off by means of the switching element 80 and the switching electronics supplied with power.
  • For switching on and off the light source 70 a variety of ways are conceivable. For example, the switching on and off via a dimmer circuit can be done so that the light intensity continuously increases or decreases.
  • Furthermore, the light intensity can be adjusted by means of a sensor to the current light conditions in the room.
  • In a further embodiment, the switching element may be formed as a flow monitor, which is a water flow through at least one of Connecting lines 142, 142 'detected. When water flows through the connecting lines 142, 142 'and thus through the sanitary fitting 10, the flow switch controls the switching electronics so that the light source is supplied with water outflow from the sanitary fitting 10 with power.
  • Turning off the light source may also be time delayed to close a valve of the mixing cartridge 144.
  • In a further embodiment, the switching element may be formed as an infrared detector, by means of which an electromagnetic valve of the sanitary fitting is driven in a known manner. The trained as an infrared detector switching element is also used to control the switching electronics, so that when running water, the light source 70 is supplied with power.
  • Another embodiment is in Fig. 7 shown. In the following, only differences to the preceding embodiment will be discussed, with the same reference numerals being used for corresponding elements.
  • The spout 50 has adjacent to the coupling surface 56 on the mounting portion, which is partially outside the fitting housing 12. The inner diameter of the outflow tube 50 expands conically from the inner diameter I outside the mounting area to an inner diameter at the coupling-in surface 56. At its end region inserted into the outflow pipe 50, the threaded bushing 150 has an outer surface that matches the inner surface of the mounting region of the outflow pipe 50 and is recessed into the outflow pipe 50.
  • The threaded bushing 150 is screwed into the housing inner body 156 to stop against the retaining ring 152, so that the threaded bushing 150 does not abut against the bottom portion 160 of the blind hole.
  • In a further embodiment, the switching element is operatively connected to the actuating element 16 in such a way that the light source 70 is switched on when water flows out through the outflow tube 50.
  • In a further embodiment, the conduit 164 is filled with a filler, for example a two-coronate casting resin.
