  • the present invention seeks to provide an actuator with user identification for the purpose of triggering a function that overcomes the disadvantages of the prior art.
  • a particularly preferred object is to provide an actuating device which allows a more reliable user identification.
  • an actuating device for a sanitary fitting is used for the purpose of triggering a function.
  • the function may be, for example, triggering a flush or turning on a light, or starting a shower, or opening a water valve in an outlet fitting, or any other function.
  • Said actuating device comprises a housing with a front side and a rear side and a detection sensor with a transmitter and a receiver for detecting a user.
  • the detection sensor emits electromagnetic waves via the transmitter and receives via the receiver the electromagnetic waves reflected by the user.
  • the detection sensor is arranged in a cavity of the housing, wherein the cavity in the direction of said electromagnetic waves has a transmission range which is transparent or permeable to the said electromagnetic waves.
  • the housing has a side surface which extends in the direction of the surface normal to the front side at least partially between the front side and the rear side, wherein the transmission region is arranged in the region of the side surface or in the side surface.
  • the transmission range is substantially such that the electromagnetic waves leak over the side surfaces of the housing.
  • the area to be detected is not an area in front of the front side, but another area, namely an area laterally, in particular below the actuator, whereby incorrect operations can be avoided.
  • the electromagnetic waves preferably pass through in the direction of a main direction through the transmission area.
  • the expression "main direction" in the present case is understood to mean a direction in which the electromagnetic waves travel shortly after being transmitted by the transmitter antenna and in which the electromagnetic waves pass through the transmission region.
  • the electromagnetic waves After passing through the transmission area, the electromagnetic waves propagate based on the local conditions and the antenna characteristic. As explained below, the electromagnetic waves can move in a circularly polarizing manner, wherein the Main axis then essentially understood as an axis around which the electromagnetic waves rotate around.

It will be the transmitted and the received electromagnetic waves passed through both the transmission area and through the gap.
  • the arrangement has the advantage that the users can be detected due to the arrangement of the transmission area and the gap, regardless of the installation situation, because the electromagnetic waves are not by elements that are in contact with the mounting plane or protruding therefrom, or by the actuator yourself, but can be reliably sent and received.

  • the materialization of the mounting plane and the element installed behind the mounting plane can be arbitrary.
  • gap is understood to mean an opening or a breakthrough or a gap.
