する装置はなかった。Conventional configuration and its problems In a dehydrating washing machine, the dehydrating/washing tub (hereinafter referred to as the water tank) rotates at high speed during dehydration, but while the rotation is increasing, the natural frequency of the vibration system and the frequency of the rotation match. When this happens, a resonance phenomenon occurs and the amplitude (swing) becomes extremely large, resulting in what is called a dangerous speed condition. At this time, if an effective damping structure was applied to the vibration system, the vibration would quickly pass through the resonance point with only a slight increase in amplitude, but there was no device with a simple configuration and stable performance.
従来の構造を第1図〜第4図によって説明する。A conventional structure will be explained with reference to FIGS. 1 to 4.

It is also rotated at high speed to perform dehydration. At this time, it is rare that the clothes are evenly distributed inside the water tank 6, and the dehydration process is performed while the clothes are unevenly distributed. This non-uniformity of the clothing results in 77 imbalance of the rotating object and causes vibration.

減衰機構によって振幅を押えねばならない。The structure supported by the vibration isolation system such as the support rod 3 and the suspension 4 is referred to as a vibration system. There is a natural frequency that is necessarily formed in this vibration system and vibration isolation system. If the frequency generated by the vibration system and the above-mentioned natural frequency match during dehydration, the amplitude of the vibration system will become extremely large, for example, it will bounce up and down, collide with the main body 1, or rotate. The shaft reaches a condition known as a resonance point, which can lead to damage at critical speeds. In order to prevent this vibration, the amplitude must be suppressed by a damping mechanism.

欠点があった。Commonly used damping methods include a method using an air damper and a method using frictional force. For example, the former method using an air tapper is provided at the lower end of the support rod 3 as shown in FIG. It is formed by a rubber cap 7 having a sealing part on the outer periphery, and a slider 8 consisting of a cylindrical part through which the support rod 3 passes through PT at the center and contacts the rubber cap 7 at the inner periphery. It has a damping effect when the air inside the slider 8 flows in and out to the outside due to the vibration of the slider.The damping performance is very stable and has a large damping effect, but the camphor and slider 8 require strict dimensional accuracy. The disadvantage is that the cost is extremely high because it requires a special surface treatment.
又、摩擦力による方法として、例えば、第3図。Further, as a method using frictional force, for example, FIG.

な減衰力を得られないという欠点があった。As shown in FIG. 4, there is a slider 8 having an inverted truncated conical shape, which is provided with a slope portion 8a whose diameter is reduced downward, and a groove portion 8b, and a damping device below which is in contact with the slope portion 8a of the slider 8. 9 is provided, and due to the weight of the vibration system, a component force P such that the slider "-8 presses the support rod 3 is generated, which is attenuated by the friction between the support rod 3 and the slider-8. Although it has the advantage of being low in cost, due to the friction between the slider 8 and the damping device 9, the component force P
However, the damping performance is unstable, and large damping force cannot be obtained.

本体1に吊り下げられている構造となる。In FIGS. 5 to 7, a lower support 50 fixed to the anti-layer receiving tank 2 has a plurality of wire strips (two wires in the actual example) made of iron wire having a diameter of about 1 to 3 mm in the aperture 10. Rod 3 penetrates. A spring holder 11 is attached to the lower end of the support rod 3, which has a through hole 11a so that the wire is fixed at a distance l, and whose through holes 11& are spaced apart from each other by e. A compression type suspension 4 is arranged on the upper part. On the other hand, between the lower support body 5 and the suspension 40, a slider 8 is provided between the support rod 3 and the slider 8, which has a through hole 8C having a diameter slightly larger than the sum of the outer diameters of the plurality of wires constituting the support rod 3. It is arranged so that it penetrates. Further, at the upper part of the support rod 3, wires are collectively fixed to a spherical body 12, and the support rod 3 is suspended from the main body 1 via the spherical body 12.

衰効果がある。The weight of the vibration system such as the washing tank 2 acts on the support rod 3, and the wire of the support rod 3 has a distance at the bottom, so when the slider 8 is not present, the sixth As shown in Figure ILK, the wire forms an isosceles triangle with the distance l as the base and the upper end of the support 3 as the apex. However, as mentioned above, the slider 8 having the through hole 8C that is slightly larger than the sum of the diameters of the wire rods passes through the support rod 3, and in the normal state, the slider 8 does not support the support rod 3. It is located above the lower end of the suspension 4 by the length of the suspension 4, and is located considerably lower when viewed from the entire length of the support rod 3. Therefore, the plurality of wire rods are forcibly gathered inward by the slider 8, and the position of the apex of the isosceles triangle formed of the wire rods becomes the lower part of the slider 8, as shown in FIG. As mentioned above, the wire rod is
Since the slider 80 tries to return to the state shown in the figure, the inner surface of the through hole 8C of the slider 80 can be pressed from inside, and as a result, a large frictional force is generated between the slider 8 and the wire, which has a damping effect.

Even if it is slightly worn, the wire always presses down on the inner surface of the slider's through hole from the inside, so there is very little variation in frictional force, etc. Also, since there are few component parts, the cost is low and it is extremely durable. It is valid.
