Description of the Related Art In a dewatering washing machine, unbalanced vibration occurs when a high-speed rotation for dewatering is performed, especially when the clothes are positioned in the dewatering / washing tub with an offset. In order to suppress this unbalanced vibration, Japanese Utility Model Publication No. 53-49988 proposes a vibration isolation device having a vibration isolation part of a closed structure. That is, the vibration-proof part has a closed structure (friction tube), a sliding plate is mounted in the friction tube, and a small amount of oil is enclosed therein. When the washing tub vibrates vertically, the friction tube also moves. At this time, the oil ascends in the groove on the inner circumference of the friction tube due to the capillary phenomenon and penetrates into the sliding plate, so that sliding between the sliding plate and the friction tube becomes smooth.

る。However, after the friction tube moves downward and the suspension compresses, when the friction tube abruptly moves up (returns) by the repulsive force of the suspension, that is, the sliding plate moves down. The air in the friction pipe below the moving plate is compressed and the pressure is high, and it works in the direction to prevent the sliding plate from moving downward, and as a result, the friction pipe itself rolls, which rolls to the washing tub. It is transmitted and the whole washing tub rolls violently, causing intermittent vibration. This intermittent vibration collides with the machine frame of the washing machine, causing abnormal vibration. A so-called shaku phenomenon occurs.

により支持具の下方への振動力が粘性減衰されるので洗
濯受槽全体がスム−ズに振動する。Function: The support moves up and down during the dehydration vibration. First, when the support tool moves downward (the sliding plate moves upward), the air in the upper space of the support tool is compressed and flows out through the gap between the suspension rod and the through hole of the support tool to the outside. In addition, it flows into the lower space through a small hole provided in the sliding plate. At this time, the downward vibrating force of the support is viscous damped by the viscous resistance of the air, so that the entire washing tub vibrates smoothly.

くなって振動、振幅を押さえて大きく減衰する。又振
動、振幅が小さければ粘性抵抗も小さくなり、それに見
合った振動の減衰が生じる。That is, in the case of viscous damping, the larger the downward speed of the support and the larger the amplitude, the greater the viscous resistance, and the vibration and amplitude are suppressed to be greatly damped. Further, if the vibration and the amplitude are small, the viscous resistance also becomes small, and the vibration is damped accordingly.

えることができる。On the other hand, when the support moves up (the sliding plate moves down), external air flows into the upper space through the gap between the suspension rod and the through hole of the support, Also, the lower space is compressed by the sliding plate and the pressure tends to rise,
It flows from the small hole of the sliding plate to the upper space. Therefore, the same viscous resistance as when the support is moved downward acts to suppress the vibration and amplitude of the support.

抗を略一定に保つ。Next, the operation of the vibration isolator 4 will be described by way of an example when dehydration occurs, in which vibrations become noticeable. At the time of spin-drying, the spin-drying and washing tub 5 itself rotates in one direction at a high speed, so that the washing tub 2 vibrates vertically and rolls. Therefore, the suspension rod 3 as a whole performs rotational vibration with a certain amplitude. Since the center of the hanging rod draws the vibration locus A of FIG. 3, the support tool 9 also rotates, and this rotational centrifugal force is applied, so that the lubricating oil U rises along the inner peripheral wall of the support tool 9 and wets the sliding plate 13. Smooths the sliding of the moving plate 13 and keeps the sliding resistance substantially constant.

るので、このフ−ト弁１６からも潤滑油が供給される。Since the sliding plate 13 vertically vibrates (slides) in the support 9, the rising lubricating oil U passes through the small hole 15 and is replenished to the foot valve 16. Particularly, when the sliding plate moves downward, the lower space inside the support tool under the sliding plate 13 is compressed and the pressure rises, so that the lubricating oil U flows from the small hole 15 to the foot together with the air in the lower space. It is supplied to the valve. Since the foot valve 16 is always in sliding contact with the inner peripheral wall of the support 9, the foot valve 16 also supplies lubricating oil.

化を防ぐことが出来る。Since the lubricating oil is supplied to the sliding plate 13 every time the water is dehydrated, the sliding resistance of the sliding plate hardly changes, and the abrasion is very small, so that the durability is improved and the anti-vibration is improved. It is possible to prevent functional deterioration.

And flows out from the sliding portion between the support tool 9 and the support tool 9. On the contrary, when the sliding plate 13 moves downward (left half diagram of FIG. 1), the lower space is compressed and the foot valve is opened by the compressed air, so that the air in the lower space flows from the small hole 15 into the upper space. Escape to.

I can. In particular, the shank phenomenon can be suppressed by reducing the viscous resistance when the sliding plate moves downward.

Since the spring 26 is attached to the spring 26, the action of the spring 26 causes a so-called intermittent vibration in which the amplitude of the washing tub 2 largely changes in a short period, but this is absorbed by the vibration isolator of the present invention. The occurrence of intermittent vibration can be suppressed.

The hermetically sealed support that spherically slides on the bottom surface of the washing tank bracket
Tool and sliding that is attached to the lower end of the hanging rod and slides inside the support tool.
The plate and the suspension interposed between the upper surface of the support and the sliding plate.
The pension, the lubricating oil enclosed in the lower part of the support, and the sliding
It is installed on the moving plate and allows the circulation of air and the lubricating oil.
Sliding contact between the small hole and the inner peripheral wall of the support provided on the sliding plate
And a valve that can be impregnated with lubricating oil.
Sliding between the upper space and the lower space inside the support during dehydration vibration
Air comes and goes through the small holes in the moving plate, and is therefore a vibration isolation device.
Can suppress the shake phenomenon during the dehydration vibration.
Furthermore, since lubricating oil is enclosed in the lower part of the support,
During dehydration vibration, the lubricating oil rises up the inner surface of the support and wets the sliding plate.
Therefore, the movement of the sliding plate becomes smooth and wear of the sliding plate is prevented.
It is possible to suppress the deterioration of the vibration isolator. Moreover, lubricating oil
Is passed through the small holes of the sliding plate due to the vibration of the support and
It reaches the upper side to impregnate the valve on the sliding plate and
The lubricating oil soaked is caused by the valve sliding on the inner wall of the support.
It is also efficiently supplied to the inner peripheral wall of the support above the sliding plate.
Wear of the sliding plate can be further suppressed, and deterioration of the vibration isolation device can be prevented.
Can be further suppressed.
