Abstract
A washing machine comprises a casing, a top cover installed on an upper surface of the casing, a door installed at the top cover, through which laundry is accommodated into the casing, and a tub installed in the casing, wherein the door is connected to the top cover by a hinge assembly or a damper assembly provided thereat. The hinge assembly includes a first hinge portion, and a second hinge portion having a torsion spring therein. The damper assembly includes a first damper portion, a second damper portion, and a ring member having a round shape and fitted into an outer circumferential surface of the second damper portion. Accordingly, even when the door has a heavy weight due to its material of a reinforcing glass, the hinge assembly or the damper assembly can endure the weight of the door. This may prevent noise or impact occurring when the door is closed.
