Abstract
The present disclosure provides a door lock device for releasably locking a door of a washing machine. The door lock device has first to third latches, and a drive motor and a latch drive mechanism for moving the third latch. The first latch releasably locks the door of the washing machine and is movable in frontward and rearward directions. The movement of the first latch is changed at a change position. The first latch is always biased frontward by a spring. The second latch releasably locks the first latch, which locks the door of the washing machine, at a door locking position. The third latch is moved in a direction perpendicular to the movement direction of the first latch. The third latch restricts the first latch at the door locking position, or unlocks the first latch after pushing the first latch from the door locking position against the spring.
