Patent number: 8590072Abstract: The sanitary fitting has an outflow pipe and a mounting base. The outflow pipe is arranged galvanically isolated from the mounting base and serves as the electrode of a sensor device. The sensor device detects whether an object, for example a hand, is present in a sensor zone or not and thereupon generates a presence or an absence signal. An electronic control system controls, in accordance with the presence or absence signal, a valve device, which controls a water flow. The electronic control system can also actuate light sources which illuminate the mounting base and the nozzle region.Type: GrantFiled: February 24, 2010Date of Patent: November 26, 2013Assignee: KWC AGInventors: Stefan Brunner, Pascal Henzmann

Patent number: 8550380Abstract: 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.Type: GrantFiled: September 21, 2009Date of Patent: October 8, 2013Assignee: KWC AGInventors: Christian Gautschi, Michael Lehner

Patent number: 8328161Abstract: 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.Type: GrantFiled: April 14, 2009Date of Patent: December 11, 2012Assignee: KWC AGInventor: Heinz Graber

Patent number: 8267118Abstract: The present invention relates to a sanitary fitting having a fitting house and having a control cartridge which is arranged in the latter. The control cartridge has a control shank which is pivotably mounted in the control cartridge. On the control shank is displaceably mounted an actuating lever which can be pivoted up and down between a closed position and an open position in order thus to control the water flow. Furthermore, a plate is mounted at one end on the guide element and at the other end on an axis of rotation which is fixedly arranged with respect to the pivot axis and which is parallel thereto. By means of this arrangement, during the pivoting of the actuating lever from the closed position in the direction toward the open position, said actuating lever is also moved in the direction away from the control shank and, in the direction of the cartridge axis, away from the fitting housing.Type: GrantFiled: September 14, 2010Date of Patent: September 18, 2012Assignee: KWC AGInventor: Andre Leutwyler
