る。(Conventional configuration and its problems) In a dehydrating washing machine, the dehydrating and 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 is extremely large, creating the risk of damaging equipment. To prevent this, the vibration system is equipped with a damping structure.

法としてエアダン・−によるものと、摩擦力によるもの
がある。The structure of a conventional example will be explained with reference to FIGS. 1 to 3. Reference numeral 1 denotes a main body, in which a washing tank 2 is supported by a support rod 3 and a suspension 4 in a vibration-proof manner. Reference numeral 5 denotes a lower support member fixed to the side plate of the washing tub 2, and the washing tub 2 is elastically supported on the upper part of the suspension 4 by the lower support member 5. 6 is a water tank, and it is rare for clothes to be evenly distributed inside this water tank 6 when washing clothes, so it was a no-brainer!'-! 1 Dehydration will be performed. This causes the rotating body to generate unbalanced υ vibrations. If the frequency generated by the vibration system during dehydration matches the natural frequency of the equipment, the amplitude of the vibration system may be too large and cause damage to the equipment. Therefore, there are two damping methods for suppressing this amplitude: one using air damping and the other using frictional force.

ないため、原価が高くつく欠点があった。The former method using an air damper is, as shown in FIG.
It is formed by a slider 8 consisting of a cylindrical portion that contacts the rubber cap 7 at its inner periphery, and produces a damping effect when air inside the slider 8 flows in and out to the outside due to vibrations of the water tank. Although the damping performance is stable, the cap 7 and the slider 8 require strict dimensional accuracy and require special surface treatment, resulting in high cost.

安定で、かつ大きな減衰力を得られない欠点があった。As shown in Fig. 3, the slider 8a has an inverted truncated conical shape with a downwardly decreasing slope and a groove, and the slider 8a contacts the inverted truncated cone of the slider 8a below. A damping device 9 having a shape of be. This method has the advantage of low cost, but due to the friction between the slider 8a and the damping device 9, the component force P does not act stably, the damping performance is unstable, and a large damping force is required. There was a drawback that I couldn't get it.

せず安定して作用するようにしたものである。A hole f(r; having a width larger than the sum of the outer diameters of the two wire rods forming the slider piece Kld support rod +16) is provided on the flat part, and the hole is a thin hole having a width that allows one wire rod to pass through. These grooves and narrow grooves are divided into two
A hole and a narrow groove are formed by aligning the flat surfaces of the two slider pieces. When the wire constituting the support rod is passed through the hole and narrow groove constructed in this manner, the wire branches into a V-shape at the branch point from the hole to the narrow groove, and the inner surface of the narrow groove is It presses elastically and creates frictional force between the wire rod and the thin grooves of the slider, which causes a damping effect.Since the wire rod elastically presses the thin grooves, there is a slight difference in the thickness of both. The frictional force, that is, the damping force, does not change and acts stably on the vehicle.

のような形状をつくる。To explain the damping effect of the above-mentioned vibration isolator, since the weight of the vibrating body such as the washing and receiving tank 2 is acting on the support rod 3a, in the state without the slider 8C, as shown in Figure 8) The two iron wires are parallel. However, this support rod 3a
passes through the slider 8C having the two V-shaped narrow grooves 8bc and 8bd as described above, so the two iron wires are forcibly intersected by the slider 8C,
As shown in FIG. 8(B), the spherical body 12 and the slider 8C

変動か少ない。(Effects of the Invention) According to the present invention, the structure is such that vibrations caused by non-uniform distribution of clothing are attenuated by the j1 friction force generated between the slider and the support rod. According to this method, even if the slider becomes slightly thick due to thick friction, the two iron wires always press the narrow grooves of the slider from inside, so there is little variation in the thick friction force.

るため、原価も安い等、種々の効果がある。In addition, due to the vertical vibration of the slider, the point where the two iron wires intersect, that is, the position of the node of the standing wave shape, changes every moment, so the two iron wires form a constant standing wave shape that changes over time. This further reduces fluctuations in thick friction force. Furthermore, the present invention has a small number of component parts, and since the slider can be manufactured by general injection molding, it has various effects such as low cost.
