It is preventing. Further, when the drum 24 starts to rotate at high speed, the vibration of the water tank 18 gradually decreases as the water is dehydrated, and at the time of steady rotation, it vibrates within the free stroke s between the sliding portion 39 and the rod 42. As a result, the piston 38 is stationary and no damper force due to the frictional force of the sliding portion 39 is generated, and the vibration is directly transmitted to the installation floor, which greatly vibrates the floor and does not cause noise or vibration of the house.

ものである。Next, another embodiment of the present invention will be described with reference to FIG. In this embodiment, the overall structure of the drum type washing machine is the same as that shown in FIG. 1, and therefore its explanation is omitted, and the difference will be mainly described below. The damper 36 is composed of a cylinder 43 and a piston 46. The piston 46 is a sliding portion 44 that closely slides in the cylinder 43 to generate a frictional force.
And a predetermined stroke s = 5.5 for this sliding portion 44.
The rod 45 is provided with a play allowance only in the range of mm, and the rod 45 is provided with a cushioning material 40 and a flange 41 in front of and behind the sliding portion 44 so as to freely slide for a certain stroke s. is doing. The stroke s
= 5.5 mm is smaller than the distance between the main body 19 and the water tank 18, and is larger than the amplitude of the water tank 18 at the time of steady rotation of dehydration.

する。The operation of the above configuration will be described. When washing and rinsing are finished and dehydration is performed, the drum 24 is rotated while the clothes are biased to the lower portion of the drum 24. At this time, the water tank 18 vibrates greatly at the time of startup due to the eccentric load of the clothes, and the flange 41 of the rod 45 collides with the piston 46 beyond a predetermined stroke s.

動するようになる。Further, when the drum 24 is rotated at a high speed, the vibration of the water tank 18 gradually decreases as the water is dehydrated. At a predetermined rotation of the water, the amplitude of the water tank 18, that is, the amplitude of the damper 36 becomes about 5 mm or less regardless of the condition of the clothes. It has been confirmed by experiments. Therefore, the predetermined stroke s is 5
By making it larger than mm, the piston 46 vibrates within a predetermined stroke, that is, a play allowance, during a predetermined rotation of dehydration.

起こすことがなくなる。As shown in the above embodiments, in the drum type washing machine of the present invention, when washing and rinsing are completed and dehydration is attempted, the drum is rotated with the clothes biased to the lower part of the drum. By the way, the water tank vibrates greatly at the time of starting due to the eccentric load due to the clothes, but the rod moves over the sliding portion of the piston over the free stroke, and the damper acts. Then, when the drum enters the high speed rotation, the vibration of the water tank gradually decreases as the water is dehydrated, and at the time of steady rotation, it vibrates within the free stroke between the sliding portion and the rod. As a result, the piston is stationary and the damper force due to the frictional force of the sliding portion is not generated, and the vibration is directly transmitted to the installation floor, which greatly vibrates the floor and does not cause noise or vibration of the house.

When you try to dehydrate after rinsing, you will rotate the drum with the clothes biased to the bottom of the drum,
The water tank vibrates greatly at startup due to the eccentric load caused by clothes, but a cushioning material is installed between the sliding part and the rod in the sliding direction.
Reliable damper action without noise caused by bumping collision
can get. Furthermore, when the drum starts rotating at high speed, the water tank vibrates.
Becomes smaller with dehydration. As a result, the piston is stationary and the damper force due to the frictional force of the sliding portion is not generated, and the vibration is directly transmitted to the installation floor, which greatly vibrates the floor and does not cause noise or vibration of the house.
