The same parts as those in the above-mentioned embodiment are designated by the same reference numerals, and the following description will be omitted. Reference numeral 39 is a spherical magnet composed of an electromagnet, and 40 is a control circuit for energizing the spherical magnet 39 for a certain period of time after the dehydration activation.

Therefore, when the dehydration is started, the spherical magnet 39 and the support magnet 38 act so as to attract each other. That is, similar to the above-described embodiment, the sliding motion of the hanging rod support portion 35 and the hanging rod support base 36 is suppressed, and as a result, the lateral vibration at the time of dehydration start is reduced. . Further, in the present embodiment, the control circuit 40 stops energizing the spherical magnet 39 after a lapse of a certain time after the dehydration activation. That is, the attraction action of the spherical magnet 39 and the support magnet 38 is lost when the dehydration is stationary. Therefore, the hanging rod support portion 35
Therefore, the suspension rod support 36 can freely slide, and the vibration of the outer tub 20 during the steady dehydration is less likely to be transmitted to the outer frame 28.

The cylindrical magnet 43 is
In this embodiment, an electromagnet is used. A control circuit 44 controls the cylindrical magnet 43.

Is attracted by the cylindrical magnet 43, so that the sliding motion between the slider 31 and the suspension rod 30 is suppressed. Therefore, the vertical vibration generated at the time of starting dehydration is suppressed and reduced. Further, in the present embodiment, the cylindrical magnet 43
The energization to is stopped after a certain period of time has passed since the start of dehydration. That is, when the dehydration is stationary, the cylindrical magnet 4
3 does not act as a magnet, and the sliding motion between the slider 31 and the suspension rod 30 is free. Therefore, the vibration of the outer tub 20 is less likely to be transmitted to the outer frame 28 during normal dehydration.

Reference numeral 39 is a spherical magnet composed of an electromagnet, and 43 is a cylindrical magnet similarly composed of an electromagnet. The spherical magnet 39 and the cylindrical magnet 43 are controlled by a control circuit 50. A support magnet 38 made of a permanent magnet is provided inside the hanging rod support 36. Further, the suspension rod 30 at the position facing the cylindrical magnet 43 is a magnetized portion 44.

わりにくくなるものである。After a certain time has elapsed after the dehydration start, the control circuit 50 controls the spherical magnet 39 and the cylindrical magnet 43 so that the polarities are reversed by reversing the energizing directions. Therefore, when the dehydration is stationary, the spherical magnet 39 and the support magnet 38 repel each other, and the support magnet 38 and the magnetized portion 44 also repel each other. Therefore, the hanging rod support portion 35
The sliding motion of the hanging rod support 36, the hanging rod 30, and the slider 31 becomes smooth, and the vibration of the outer tub 20 is less likely to be transmitted to the outer frame 28.
