Damping device for a washing machine, and washing machine

A washing machine, comprising a damping device, the damping device including a damping suspension rod;

• an upper bracket;
• a damping spring;
• a sliding damping support seat;
• and
• a sliding damping piece, wherein an upper end of the damping suspension rod is installed on a cabinet of the washing machine, the upper bracket is installed on an outer tub of the washing machine, and the damping suspension rod passes through the upper bracket, the sliding damping piece, the sliding damping support seat and the damping spring in sequence from top to bottom, and
• the sliding damping piece includes an annular damping fin, multiple damping blocks arranged at one side of the annular damping fin and distributed along an inner ring of the annular damping fin, and a through hole located in a center of the annular damping fin to allow the damping suspension rod to pass through, the through hole being formed by the damping blocks,
• the damping spring is configured to contract, and the sliding damping piece is configured to tighten and generate a sliding damping acting on the damping suspension rod when the outer tub of the washing machine shakes or swings to apply an eccentric pressure to the upper bracket,
• the sliding damping support seat and the sliding damping piece are configured to simultaneously tighten to increase the sliding damping acting on the damping suspension rod when the eccentric force increases, and
• the damping spring is configured to extend, the sliding damping support seat and the sliding damping piece are configured to gradually loosen, gradually reducing the sliding damping acting on the damping suspension rod when the outer tub of the washing machine shakes or swings to release the upper bracket.
