Abstract
Provided is a laundry treatment machine. The laundry treatment machine may include a main body, a lid, and at least one hinge that supports the lid. The hinge may include a hinge housing filled with a fluid having a prescribed viscosity, an elastic member disposed inside the hinge housing, and a pair of cams disposed in the housing to move in linkage with the lid and the elastic member. A piston may be disposed between the moving cam and the elastic member to deform the elastic member according to a displacement of the moving cam. The piston may divide a cavity inside the hinge housing into a first space in which the elastic member is disposed and a second space in which the pair of cams are disposed. The piston may include a passage for the fluid to flow between the first space and the second space.
