Description

The present invention relates to the technical field of a washing machine, and specifically to a dumping suspension rod structure of a washing machine and a washing machine.

Existing pulsator-type washing machines suppress vibration mainly by spring parts in hanging rods, and generally exhibit a mounting angle of about 7 ° in the vertical direction. Therefore, the spring resistance of the suspension rod is mainly decomposed into vertical forces, and the component force in the horizontal plane is small. That is, the vibration in the vertical direction is mainly suppressed, but the vibration in the horizontal plane cannot be effectively suppressed.

The existing Chinese invention patent, whose application number is 201410599273.2 and whose name is the washing tub dampening device and washing tub, discloses the washing tub dampening device, which discloses a hanging bar, a horizontal bar, a hanging bar and a horizontal bar. Includes a slide loop to connect. The horizontal bar is attached to the washing tub, the upper attachment part of the hanging bar is attached to the washing machine housing, and the lower attachment part is attached to the washing tub. The horizontal bar controls the lateral sway and vibration of the washing tub, and the hanging bar controls the sway and vibration of the washing tub in the depth direction. As a result, the vibration of the washing tub can be reduced during the operation of the washing tub, and the noise of the operation and the vibration of the entire washing machine are reduced.

The washing tub damping device in the above patent adds a horizontal bar between the existing hanging bar and the outer tub and a slide loop connecting the hanging bar and the horizontal bar, and the inner and outer tub assemblies vibrate in the horizontal direction during dehydration. Can be effectively suppressed. However, when the washing machine rotates at low speed and the eccentricity is relatively large, the tub assembly may sway up and down. At this time, the spring at the bottom of the suspension rod alone cannot prevent the tub from swaying up and down. Can not.

In consideration of this, the present invention is shown in particular.
