ても振動が小さく低騒音で運転できるものである。Function The automatic washing machine of the present invention has the above-mentioned configuration, so that at the time of startup of dehydration, the enclosed fluid accumulates in the fluid balancer provided near the center of gravity of the hanging part at the bottom of the dehydration tank, and the vicinity of the center of gravity becomes heavy and unbalanced, causing the fluid to come out. The inertial force of the fluid balancer allows the tank to smoothly transition to steady rotation with a relatively small amount of whirling. During steady rotation, the sealed fluid in the fluid balancer rises toward the top of the dehydration tank through the hollow chamber provided in the side wall of the dehydration tank on the opposite side of the unbalance, so that the sealed fluid concentrates on the opposite side of the unbalance. , the correction force increases and the unbalanced force is completely canceled out. As a result, even when the fabric is unbalanced to an excessive extent, vibrations are small and the machine can be operated with low noise.

である。With the above configuration, when dehydration is started, the sealed fluid 19 is accumulated in the fluid balancer 15 provided near the center of gravity of the hanging part at the bottom of the dehydration tank 14, and the vicinity of the center of gravity becomes heavy (as a result, the outer tank 10 swings due to unbalance). The inertial force of the fluid balancer 15 causes the fluid balancer 15 to smoothly transition to steady rotation with a relatively small whirlwind.During steady rotation, the sealed fluid 19 in the fluid balancer 15 is transferred to the dehydration tank 14 on the opposite side of the imbalance. The fluid 19 rises toward the top of the dehydration tank 14 inside the hollow chamber 17 provided on the side wall of the lance, and the enclosed fluid 19 is concentrated on the opposite side of the lance, increasing the correction force and completely canceling out the unbalanced force. As a result, even when the fabric is unbalanced, vibrations are small and the machine can be operated with low noise.
