A door lock for an oven includes a lock housing, a geared motor, an
actuating shaft to be driven by the geared motor, a retaining plate and a
locking element formed as a lever to be operated by the actuating shaft.
The lever is mounted on the retaining plate and has a lever axle for
reversibly changing location relative to the lock housing. A spring
exerts a force being overcome in an emergency-unlocking function
permitting adjustment of the retaining plate to allow opening of the
lever having been previously brought into a locking position by the
actuating shaft, without further operation of the actuating shaft. The
actuating shaft is adjustable along its axis by the lever having been
unlocked in an emergency.
