Abstract

本发明提供一种洗衣机,能够保证作为工作流体使用磁流变流体的所谓阻尼器构成部件的磁轭的高精度,同时低成本制造。用于衰减收容滚筒(旋转槽)的水槽的振动的阻尼器(21),通过由收容在缸体(22)内部的线圈(43)产生的磁场,对棒(23)与上下两个磁轭(45)、(36)之间的磁流变流体(55)施加磁力从而提高该磁流变流体(55)的粘度,增加对于棒(23)往复运动的摩擦阻力使得阻尼力变大,从而防止水槽发生振动,其中,用于诱导由线圈(43)产生的磁场的上下两个磁轭(45)、(36),通过烧结磁性金属粉末而形成。
The invention provides a washing machine, which enables the precision of magnet yokes used as working fluid and using a damper component of a magneto-rheological fluid to be high and is low in manufacture cost. The damper (21) used for attenuating the water groove vibration of an accepting roller ( rotating groove ) applies magnetic forces on the magneto-rheological fluid (55) between a rod (23) and two up and down magnet yokes (45, 36) via a magnetic field generated by a coil (43) accommodated in the interior of a cylinder body (22), so that the viscosity of the magneto-rheological fluid (55) is improved; by increasing the frictional resistance of the rod repeated movement, the damping force is increased, so that the water tank can be prevented from vibrating; wherein the up and down two magnet yokes (45, 36) used for inducing the magnetic field generated by the coil (43) are formed by sintering magnetic metal powder.
