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.
