Method and electronic control apparatus for contactlessly controlling a sanitary facility

Abstract

The present invention provides a method for contactlessly controlling a sanitary facility and provides an electronic control apparatus thereof. In the method, a transmitter, a receiver, an evaluation unit and a control unit are used to monitor an area (2) of the sanitary facility (1) and to control at least one actuator (5) of the sanitary facility. The area (2) is monitored using a time-of-flight distance measurement. In particular, the spatial position and / or the speed and / or the direction of movement of objects (7) in the area (2) being monitored is / are detected.

Description

technical field [0001] The invention relates to a method of controlling a sanitary facility in a contactless manner and an electronic control device using a transmitter, a receiver for monitoring an area of ​​a sanitary facility and controlling at least one actuator of the sanitary facility , evaluation unit and control unit to control the sanitation facility in a non-contact manner. Background technique [0002] Such a method and such a control device are known as prior art by the applicant in EP-B-0670504. In this case, in particular, the sanitary facility is a urinal. In order to measure distance by triangulation, the device has two receivers arranged at different distances from the transmitter. Such control means can be used to detect a user and trigger flushing. Reflections from the background can be masked. [0003] Touchless controls with infrared light sensors installed in water fittings are also known. When a hand is placed in the detection zone of the light se...
