No matter which type of washing machine is provided with the motor, the vibration problem is always a great problem of the washing machine, the problems of overlarge vibration, displacement, collision of an outer barrel with a box body and the like are caused in many types of washing machines, and the use performance of the washing machine is seriously influenced and limited.
The prior pulsator washing machine adopts a design of a balance ring and a spring suspender, or adds a damping structure at a spring part; the drum washing machine adopts the design of matching a balance weight, a damper and a balance ring. The prior pulsator washing machine comprises a box body, an outer barrel part and the like, wherein the outer barrel part and the box body are arranged together through four suspender vibration reduction parts. The upper part of the damping part of the suspension rod is provided with a suspension rod seat, the lower part of the damping part of the suspension rod is provided with a sleeve and a spring, the sleeve at the lower part of the damping part of the suspension rod is clamped in a suspension hole of the outer barrel, and the suspension rod seat at the upper part is arranged in holes of reinforcing plates at four corners of the box body. When the clothes inside the outer barrel part shift during the washing or dewatering process and the outer barrel part vibrates due to unbalance, the inner barrel balance ring and the suspender vibration reduction part play the roles of vibration reduction and balance adjustment. However, when the full-automatic washing machine is operated for dewatering and starting, the outer tub can shake or swing along with the starting of the motor to form larger vibration and noise, the suspension rod of the vibration reduction component can also shake when the outer tub swings, and the suspension rod can swing in different directions from front to back and left to right on the suspension seat of the outer tub.

However, the hanger rod itself is a movable part, and the rubber belt is connected with the hanger rod and the outer barrel cover at one point, so that displacement sudden change is easily generated, the vibration reduction effect is not good, and the problem that the vibration of the washing machine, even the outer barrel collides with the box body, cannot be fundamentally solved.
Then, patent 201110227646.X discloses a full-automatic washing machine with dual vibration reduction functions, which comprises a box body, an outer barrel, a transmission system and a control system, wherein the outer barrel and the box body are installed together through four suspender vibration reduction components, a vertical plate-shaped vibration reduction belt which plays a role in auxiliary vibration reduction is further installed between the outer barrel cover and the box body, two ends of the vibration reduction belt are provided with stand columns, a pair of hollow columns are arranged in the middle of the vibration reduction belt at intervals, a pair of fixed columns are arranged on a box body corner reinforcing plate, a pair of clamping grooves are formed in the outer barrel cover, and the stand columns and the hollow columns of the vibration reduction belt are respectively clamped and spliced with the outer barrel cover clamping.

The present invention has been made in view of this situation.
