Definitions

  • the present invention relates to a movement device for moving a closure element for closing a drain opening, in particular a drain opening of a sink or a washstand, wherein the movement means comprises an electromagnetic drive device for driving a movement of the closure element from an open position in which the closure element releases the drain opening in a Closed position, in which the closure element closes the drain opening, and wherein the electromagnetic drive device comprises a magnetic coil, to which an electrical voltage can be applied.
  • Such a movement device is from the DE 42 41 023 A1 known.
  • the magnetic coil of the electromagnetic drive device is subjected to a voltage that is constant in time in order to move the closure element from the open position to the closed position and then to hold it in the closed position. By switching off this electrical voltage, the closure element is moved back from the closed position to the open position.
  • the present invention has for its object to provide a moving means for moving a closure element for closing a drain opening of the type mentioned, which moves the closure member quickly and reliably from the open position to the closed position and yet has a low energy consumption.

  • a sufficiently high closing force is available during the closing operation of the closure element in order to move the closure element rapidly from the open position into the closed position.
  • the holding voltage is preferably selected so that the magnetic attraction force generated upon application of this holding voltage to the magnetic coil is just large enough to retain the closure element in the closed position.
  • the holding voltage in the closed position of the closure element is substantially constant in time.
  • the closing voltage during the closing operation substantially continuously or stepwise, in several stages, increase.
  • the closing tension during the closing operation in a staircase i. in a plurality each substantially substantially equal steps, up to a maximum closing voltage increases.

  • the opening voltage during the opening process substantially continuously or stepwise, in several stages, decrease.
  • the opening tension during the opening process in a staircase i. with a plurality of each substantially equal high steps, decreases to zero.
  • the movement device comprises a restoring element which biases the closure element in the open position. This ensures that in the case of a power failure, when applied to the solenoid no electrical voltage, the return element moves the closure element back into the open position, so that in case of power failure, the drain opening is open and no water overflow even when water is supplied to the sink or to the washstand can.
  • Such a restoring element may in particular comprise a spring element, for example a compression coil spring.
  • the holding voltage which is applied in the closed position of the closure element to the magnetic coil, is preferably selected so that the magnetic holding force generated by the holding voltage is greater than or equal to the restoring force of the return element.
  • the holding voltage is chosen so that the magnetic holding force generated by the holding voltage is only slightly larger, in particular by at most about 10%, greater than the restoring force of the return element in the closed position located closure element.
