A home appliance, comprising:
- a cabinet having a storage space formed inside and an opening communicating with the storage space;
- a door rotatably coupled with the cabinet to open or close the opening;
- a latch provided at one of the door and the cabinet;
- and
- a coupler provided at the other one of the door and the cabinet, the coupler including:
- a housing including a latch insertion hole into which the latch is inserted;
- an engaging lever, the engaging lever including an engaging lever body rotatably provided within the housing, a latch insertion groove having an end of the latch inserted therein by extending from a first end of the engaging lever body, and a first projection, a second projection, a third projection, and a fourth projection formed by a plurality of extending portions of a second end of the engaging lever body;
- an engaging lever torsion spring provided at the engaging lever to provide an elastic force so as to enable the latch insertion groove to rotate toward the latch insertion hole;
- an operating lever configured to move away from the latch insertion hole by being pressed by the first projection and rotate with respect to a first shaft attached to the operating lever;
- a first spring providing a restoration force to enable the operating lever to be restored into a state before being pressed by the first projection;

A latch lock for a home appliance including a door and a cabinet, the latch lock comprising:
- a latch bar protruding from an interior surface of the door and including a latch hole;
- and
- a coupler attached to the cabinet and including a latch insertion hole configured to receive the latch bar, wherein the coupler includes:
- an engaging lever including an engaging lever body configured to rotate about a first axis when contacted by the latch bar and including a first insertion projection and a second insertion projection extending from a first side of the engaging lever, and a first projection, a second-projection, and a third projection extending from a second side of the engaging lever, wherein the second insertion projection is configured to be inserted into the latch insertion hole when the latch bar is received in the coupler;
- and
- an operating lever configured to slide in a first direction and to rotate about a second axis different from the first axis when contacted by the engaging lever and including a header on a first end having a first incline and a second incline configured to interact with the first projection, and a release bar having a release portion incline configured to interact with the third projection, wherein when the door is closed and the latch bar is received in the coupler, the first projection presses the first incline of the header such that the header is received in a recess formed between the first projection and the engaging lever body, and wherein when the door is opened, the third projection pushes the release portion incline such that the operating lever rotates about the second axis to move the header out of the recess.
