DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-vibration device for a dehydrating / washing machine in which a water tub is elastically supported by a washing machine main body.

[0002]

2. Description of the Related Art Hitherto, a dehydrating / washing machine provided with such a vibration isolator has been configured as shown in FIG. Hereinafter, the configuration will be described.

As shown in FIG. 8, a washing / dehydrating tub 2 is rotatably disposed inside a water receiving tub 1, and a fluid balancer 3 for damping dehydrating vibration is provided at an upper end of the washing / dehydrating tub 2. The pulsator 4 is fixed at the bottom of the center so as to be rotatable. A speed reducer 7 connected to a motor 5 and a belt 6 is fixed to a lower portion of the water receiving tank 1. The drive shaft of the speed reducer 7 has a double structure. The washing and dewatering tub 2 is fixed to the outer shaft, and the pulsator 4 is fixed to the inner shaft.
In addition, the water receiving tub 1 is located at four corners of the main body 8 of the washing machine.
Is supported by a suspension 10 via a support piece 9 provided integrally with the suspension.

As shown in FIG. 9, a suspension 10 is provided with a spring support 12 at the lower end of a suspension rod 11, a compression coil spring 13 is mounted on the spring support 12, and a damper 14 is further mounted thereon. Is placed and supported. The damper 14 includes a cylinder portion 15 having a flange 15a on the outer periphery of an upper portion, and a piston portion 16 having a large-diameter receiving portion 16a on an upper end portion.

[0005] In the lower half of the inner peripheral surface of the cylinder 15, a tapered portion 15b whose diameter decreases toward the bottom is formed. On the other hand, the lower half portion of the piston portion 16 also forms a tapered portion 16b corresponding to the cylinder portion 15.
Further, a plurality of disk-shaped damping members 17 as shown in FIG. 10 are stacked and housed in the tapered portion 15b.

The damping member 17 is made of a soft material such as felt, and has an outer diameter of the cylinder portion 1.
5 is set slightly smaller than the inner diameter of the upper portion and larger than the minimum inner diameter of the tapered portion 15b. Grease is applied as a lubricant to sliding parts of the piston part 16 and the damping member 17.

The damper 14 is vertically movably inserted through the lower part of the suspension rod 11, and supports the flange 15a of the cylinder part 15 on the compression coil spring 13. At the same time, the water receiving tank 1 is supported by the receiving portion 16a of the piston portion 16. At this time, the damping member 17 provided in the cylinder portion 15 acts to reduce the diameter by tightening the suspension rod 11 by being inserted into the small-diameter taper portion 15b. That is, the damping member 17 slides frictionally on the suspension rod 11.

With the above configuration, water supply, washing, drainage,
Perform centrifugal dehydration automatically. In general, in a washing machine for both dehydration and washing, when the washing process is completed and a dehydration process for rotating the washing and dewatering tub 2 is started, the clothes, which are the laundry, are biased. Large vibrations occur in the water tank 2 and the water receiving tank 1. This vibration becomes maximum especially when the motor passes through a rotation speed corresponding to a vibration resonance point of the water receiving tank 1 or the like at the time of startup.

In order to suppress the vibration caused by the resonance, the vertical movement of the damper 14 is used as a damping force. That is, when the damper 14 moves downward, a frictional force acts between the damping member 17 and the suspension rod 11, and the frictional force acts as a damping force, so that the above-described vibration can be damped. Further, the greater the amount of laundry, the more strongly the damping member 17 is compressed, and the greater the pressure contact force on the hanging rod 11, so that a greater damping force can be obtained and the amount of vibration attenuation also increases.

[0010]

However, in such a conventional configuration, the cylinder portion 15 and the piston portion 1 are not provided.
6 and a disk-shaped damping member 17 which is stacked and stored below the cylinder portion 15 and has a large number of parts and a complicated configuration. Due to variations in the dimensions of the parts, the damping force originally required in the dewatering process may not be obtained, or an excessive damping force may be generated. Vibration becomes extremely large when passing through the number of rotations corresponding to the vibration resonance point, and in the worst case, the water receiving tub 1 collides with the side surface of the washing machine main body 8 or collides with the top plate. There is a problem that the washing machine body 8 moves.

Since there is a clearance between the inner diameter of the cylinder 15 and the piston 16 and the outer diameter of the suspension rod 11, the cylinder 15 and the piston 16 are slightly inclined from the axial direction of the suspension rod 11. At this time, the damping member 17 provided at the lower portion of the cylinder portion 15 is inserted into the small-diameter taper portion 15b, and the upper surface is sandwiched by the piston portion 16. The damping member 1
7, the sliding rod 11 slides while receiving a lateral load, and thus has a problem that uneven wear easily occurs.

The present invention solves the above-mentioned conventional problems and reduces the number of parts, simplifies the structure, generates a stable damping force, and prevents the water receiving tub from hitting the side of the washing machine body or the top plate. Prevent the washing machine from moving,
A first object is to suppress vibration during dehydration and reduce noise.
