Abstract: Door lock for a door of a household appliance with a first device for detecting a closed state of the door, and a second device for locking the door, wherein the first and second devices are electrically connected in series.

Abstract: The solution according to the invention is based upon the knowledge that the undesirable hysteresis of the force-path function in door locks (1) can be avoided or at least minimised if the (frictional) forces acting during transitions from open positions to closed positions and vice versa are minimised and/or avoided. In this respect, the invention is based upon the starting point of at least reducing (frictional) forces acting in bearings for rotatable components (14, 18, 28) of door locks (1) and/or between surfaces (22, 30) displaceable relative to one another. In this manner, it is attained that forces required for a transition from a closed position to an open position essentially correspond to forces required for a transition from the open position to the closed position.

Abstract: The present invention provides an apparatus for blocking and releasing a door lock of an electrical appliance, such as e.g. a washing machine, a dishwasher or a tumble drier. In said apparatus, use is made of a blocking and release unit, which in a blocking state blocks the locked door lock in order to prevent unlocking of the door lock. In a release state the blocking and release unit enables unlocking of the door lock in that it releases the still locked door lock. Furthermore, an emergency release unit, which is constructed separately from the blocking and release unit, is used to bring the blocking and release unit automatically into the release state in an abnormal operating state of the electrical appliance, such as e.g. in the event of a power failure.

Abstract: The present invention provides a method for a door latch of a household appliance wherein the unit includes at least one memory metal actuator which generates forces desired during use of the door latch.

Abstract: A door latching mechanism for the door of an electric household appliance, in particular a washing machine, is described. The door latching mechanism comprises an element (34) of which at least a deflection part changes its spatial position (C, D) upon a change in temperature of the element (34) and thereby operates a bar element (32) for locking and unlocking the door. The door latching mechanism further comprises an electromagnetic device (46) comprising an actuating member (48) for unlocking the door. The actuating member (48) cooperates with an extension (40A) of the bar element (32).
