  • Publication number: 20100206956
    Abstract: A sanitary fitting includes a cold water connection; a hot water connection; a mixed water outlet; a valve device for setting a mixed water temperature and a mixed water throughflow rate, wherein the valve device is connected to the cold water connection and the hot water connection at one end and is connected to the mixed water outlet at the other end; an electrical controller for actuating a valve; and a control signal transmitter for generating an input signal to the controller, wherein the valve is an integral constituent part of the valve device, and the controller actuates the valve device as a function of the input signal of the control signal transmitter such that a mixed water temperature and a mixed water throughflow rate are set.

  • Publication number: 20100084487
    Abstract: The spray head has a housing-mounted inflow passage for feed water, and a central first outflow passage. A second and a third outflow passage are offset in the circumferential direction with respect to an axis of rotation. Each of the outflow passages is connected to a corresponding water outlet for producing different spray jets. A control element having a connecting channel is disposed in the interior of the spray head and is rotatable about the axis of rotation by the actuating element. The actuating element can execute a lifting movement. In the starting position of the actuating element, the connecting channel exclusively connects the inflow passage to the first outflow passage. In the lifting position of the actuating element, the inflow passage is connected either to the second or the third outflow passage as a function of the actuating element and the associated rotational position of the control element.

  • Patent number: 7614424
    Abstract: The sanitary fitting (10) has an outflow conduit system (40) which can be telescoped by a displacement distance (H). The outflow conduit system (40) has an inner tube (42), which is retained by a base unit (39), and an outer tube (44), which can be moved longitudinally in relation to the inner tube (42). The inner tube (42) has a closed tube end (48) and, at a spacing from the closed tube end (48) which corresponds at least to the displacement distance (H), a radial through-passage (50). The radial through-passage (50) connects an interior of the inner tube (42) on a permanent basis to a lateral space (70) of constant volume, the lateral space being bounded by the inner tube (42) and the outer tube (44). Longitudinally running throughflow channels (78) run through the outer tube (44) to a free end region of the outer tube (44), in which water passes out of a water-outflow opening (90) when the control cartridge (18) is open.

  • Publication number: 20090256096
    Abstract: The fitting housing contains a control cartridge, of which the control shank can be pivoted about the pivot axis. The actuating lever can be displaced relative to the control shank, is mounted on the latter and can be pivoted via its own lever axis, this lever axis being guided in the guide track. When the actuating lever is pivoted up and down, it executes a displacement movement relative to the control shank, and this prevents contact between the actuating lever and the fitting housing.

  • Patent number: 7467874
    Abstract: A sanitary fitting includes a light-permeable water-carrying outflow pipe that has (i) an exposed end face and (ii) an input face located upstream of the exposed end face. A light source, preferably including light emitting diodes (LED), inputs light into the outflow pipe through the input face. The light emerges from the outflow pipe at the end face, and may also emerge at an exposed outer peripheral surface area of the outflow pipe.

  • Publication number: 20080202611
    Abstract: A control cartridge (20) is inserted into the fitting housing (10). Mounted on the actuating shaft (38) of said cartridge is an actuating body (42) on which the tubular actuating lever (50) is fastened. A light guiding element (52) runs through the actuating lever (50). The light source (66) in the actuating body (42) emits light that is guided to the end of the actuating lever (50) by means of the light guiding element (52).

  • Publication number: 20080196160
    Abstract: The rinsing device comprises a flexible connecting pipe which at one end is connected to a connecting element which may be attached to a fitting and at the other end bears a spray head with an actuating lever. The spray head is held on a holder, which protrudes outwardly from the connecting element. The connecting pipe comprises a flexible water feed pipe which is surrounded by a casing element, which is formed by a single spiral tension spring consisting of one piece. Said spiral tension spring consists of a first upright spring portion having a straight spring axis, a second curved spring portion attached thereto and a third, similarly upright spring portion having a straight spring axis, which is attached to the second spring portion. A tube-shaped protective casing extends around the casing element which protects the casing element from soiling.
