Abstract
The present application discloses a door lock, which may be implemented on a door panel of an electrical device such as a washing machine. The lock includes a housing that can be installed into the panel without hardware such as a mounting screw, eliminating a need to position a screw in the panel for mounting the lock. The lock housing may include a lock head that can move into or out of a groove formed as a recess into a clamping edge of the housing. Ramped surfaces and contact faces of the housing are provided that allow rotation of the housing during its installation into the panel, which force the lock head into the groove during the housing insertion into the panel and allow the lock head to restore by moving out of the groove when the housing is in an installed position, locking the housing in place.

- a housing;
- a door hook hole body provided on the housing, wherein the door hook hole body comprises a top, a first pair of oppositely provided sidewalls, and a second pair of oppositely provided sidewalls, and the first pair of sidewalls and the second pair of sidewalls are formed respectively by extending downward from the lower part of the top;
- a pair of clamping edges comprising a first clamping edge and a second clamping edge, the pair of clamping edges extending outward respectively from the first pair of sidewalls from the top of the door hook hole body;
- a groove formed by upward recessing from the lower surface of the first clamping edge;
- and
- a lock head provided below the groove, wherein the lock head is capable of moving into or out of the groove;
- wherein a pair of first contact faces and a pair of second contact faces are respectively formed by the housing extending from the outer sides of the second pair of sidewalls, the pair of second contact faces are respectively formed by the distal ends of the pair of first contact faces extending obliquely downward, and a pair of supporting parts are formed at the junctions of the pair of first contact faces and the pair of second contact faces.

- a panel provided with an installation hole,
- a door lock configured for installation on the panel and including:
- a housing;
- a door hook hole body provided on the housing,
- a pair of clamping edges extending outwardly from the door hook hole body;
- a groove formed by upward recessing into one of the pair of clamping edges;
- and
- a lock head provided with respect to the groove for moving into or out of the groove;
- a first pair of contact faces extending from the housing;
- a second pair of contact faces extending from the housing;
