摘要

The present invention discloses an improved door assembly and a washing machine and a dryer having the same applied thereto. The door assembly of the present invention includes a hinge assembly (150), a door body (200), a hook assembly (300), a lock assembly (400). Since, in the present invention, the hand hold formed in the door body (200) is recessed in an inner circumferential surface of the frame (210) so as not to be visible from an exterior, an outer appearance of the appliance is improved. Of components of the hook assembly (300), since the bracket (320) having a shaft (340) with a hook (310) inserted therein is formed as a unit with the bracket (320) on an inside thereof, with a reduced number of the hook assembly smaller than the related art, an assembly process can be simplified and productivity is improved. The lock assembly (400) provided to the cabinet (100) to hold the hook (310) includes a hook holding device and a locking device. The hook holding device holds the hook (310) by using an elastic force of the hook (310) when the hook (310) is inserted therein, and release the hook (310) when the hook (310) is drawn. The locking device, operative in response to an external electric signal, maintains the held state of the hook (310), for preventing the body (200) from being forcibly opened by an external force, thereby preventing occurrence of fault and accident caused by negligence of safety.
