Abstract
A door latch is particularly suited for a washing machine door. The device has a pivotally mounted rotary catch for latching onto a locking element and a pivotally mounted blocking or arresting element. The latter is pivotally mounted between a latching position that latches the rotary catch and an unlatching position that releases the rotary catch. The arresting element can be actuated by a bimetallic adjusting element, which can be heated by a heating element, and by an actuator system that, at the same time, is actively connected to the turning catch in a direct manner. A torque component effected on the arresting member by the actuator system is greater in value that a torque component introduced by the bimetallic adjusting element.
Claims10
A locking device, comprising:
- a pivotally mounted rotary catch for locking a locking member;
- a pivotally mounted arresting member to be pivoted between a locking position, wherein said rotary catch is locked, and an unlocking position, wherein said rotary catch is released;
- a bimetallic actuator element disposed to effect a first torque on said arresting member for actuating said arresting member, and a heating element for heating said actuator element;
- and
- an actuator system in direct operative connection with said rotary catch and disposed to effect a second torque on said arresting member for actuating said arresting member;
- the second torque transmitted to said arresting member by said actuator system being greater than the first torque transmitted to said arresting member by said bimetallic actuator element.
