A washing machine is provided to absorb vibration in a washing or a dehydration process by generating magnetic field in a case to increase viscosity of MR fluid. A washing machine comprises a case(110), a piston unit(120), elastic members(130), and a coil(140). The case is installed at the lower part of the washing machine body to support the washing machine body, and is filled with MR fluid. A plunger(150) is formed in the center of the case to generate strong magnetic field through the coil. The piston unit has a piston head(121) and a piston rod(124). The piston head is placed in the case. A through hole(122) is formed at the piston head to make the MR fluid in the case flow to the upper or the lower part of the piston head. The piston rod is extended from the piston head to the outside of the case. The elastic members are aligned at the upper and lower parts of the piston head respectively, and regulate balance of the washing machine body. The coil generates magnetic field in the case by receiving current. The coil is wound on the outer surface of the case to increase viscosity of the MR fluid. |
