Zusammenfassung:	An appliance includes a hinge module between a main body and a pull-down door. The hinge module includes a housing, a rotational axis member disposed in the housing serving as a center of rotation between the pull-down door and the main body, an inner link housing movably disposed in the housing that moves with the opening of the pull-down door in a direction of the rotational axis member, and a damper installed in the inner link housing, the damper including a piston and a cylinder and providing damping force according to a relative movement of the piston and the cylinder. Any one of the piston and the cylinder of the damper moves with the inner link housing and the other of the piston and the cylinder of the damper moves by a predetermined distance as the inner link housing moves and then is interfered by the housing so as not to move further, and the piston and the cylinder of the damper starts damping, wherein the predetermined distance corresponds to an opening angle of the pull-down door in which the damping is started.
