Description

  TECHNICAL FIELD The present invention relates to the technical field of washing machines, and more particularly to a dumping suspension bar structure for washing machines and washing machines.

  The existing pulsator type washing machine is mainly damped by the spring part in the suspension rod, and generally exhibits a vertical direction and a mounting angle of around 7 °. The spring resistance of the lifting rod is therefore mainly resolved into vertical forces and the horizontal component is small. That is, although the vibration in the vertical direction is mainly suppressed, the vibration in the horizontal plane can not be effectively suppressed.

The horizontal bar controls the lateral shaking and vibration of the washing tub, and the lifting bar controls the shaking and vibration in the depth of the washing tub. This can reduce the vibration of the wash tub during operation of the wash tub, reducing the noise of operation and the vibration of the entire washing machine.

  The damping device in the above-mentioned patent adds a cross bar between the existing sling bar and the outer tub, and a slide loop connecting the sling bar and the lateral bar, and the inner and outer tub assembly vibrates horizontally during dewatering. Can be effectively suppressed. However, when the eccentricity is relatively large during low speed rotation of the washing machine, the tank assembly may shake up and down, and at this time, it is possible to prevent the tank from shaking up and down only by the spring at the bottom of the suspension rod. Can not.

  In view of this, the invention is particularly illustrated.
