Overlifting door latch with locking mechanism

A door latch for an electrical domestic appliance, the door latch comprising:

• a rotary member which is arranged to be rotationally movable in a rotation plane between a closing rotational position and a release rotational position wherein the rotary member is spring-biased in the direction towards the release rotational position and is configured to hold, in the closing rotational position, a closure member in order to keep a door of the domestic appliance closed and to release, in the release rotational position, the closure member in order for the door to open;
• a movably arranged catch for arresting engagement with the rotary member in its closing rotational position, wherein the rotary member is provided with a sliding guide for sliding engagement by the catch as the rotary member undergoes rotational movement, wherein the arresting engagement is defined by the catch engaging behind an arresting edge formed by the sliding guide, the arresting engagement preventing the rotary member from rotating back to the release rotational position, wherein the arresting engagement is releasable by rotating the rotary member beyond the closing rotational position thereby permitting the catch to spring away sideways from the arresting edge;
• and
• a locking slider arranged to be movable between an unlocking position and a locking position, the locking slider configured to block, in its locking position, the rotary member against rotation out of the closing rotational position into the release rotational position when the door is closed and permit, in the unlocking position, such rotation of the rotary member,
• wherein the locking slider forms a first blocking arrangement configured to be clamped between the rotary member and an abutment structure when the locking slider is in the locking position and the rotary member is in a clamping rotational position lying between the closing rotational position and the release rotational position,
• wherein the locking member forms a second blocking arrangement configured to block the catch in at least one movement direction in the locking position of the locking member.

• a locking slider arranged to be movable between an unlocking position and a locking position, the locking slider configured to block a movable component of the door latch when the door is closed;
• and
• a carrier lever for the rotary member which is arranged to be displaceable against spring force out of a rest position into an emergency opening position, wherein the catch is arranged to be lifted out of arresting engagement with the rotary member by striking a stop element upon displacement of the carrier lever out of the rest position into the emergency opening position, wherein the stop element is formed on the locking slider and is moved in the locking position of the locking slider out of a standby position, in which the stop element is ready for striking by the catch.
