  • an optional securing device 24 is also provided which selectively releases or blocks the drive device 14 or its activation by the control device 18.
  • the securing device 24 executes this release / blockade of the drive device 14, for example, as a function of an operating state of the respective household appliance.
  • operating states of a household appliance are conceivable in which an opening of the door 12 should be prevented.
  • a security device 24 represents a further effective measure for the protection of the household appliance and the user.
  • This safety device 24 is connected to a display device 26, which indicates to the user when operating the actuating device or one of its sensor fields 20a, 20b, 20c, a blockage or even a malfunction of the drive device 14 for the door 12.
