In some embodiments of the present invention, the damping strip 60 is interposed between the upper spring seat 40 and the upper bracket 50, inside the housing chamber 41; preferably, the damping strip 60 is an annular friction plate, and one end face of the damping strip 60 faces the end face of the support ring 52, and the other end face faces the bottom wall of the accommodating chamber 41;
further, the damping bar 60 is in an interference fit with the upper spring seat 40 and the upper bracket 50, that is, the damping bar 60 is tightly clamped in the accommodating chamber 41 of the upper spring seat 40, when the eccentric force of the washing tub is large, the support ring 52 slides into the accommodating chamber 41 to contact with the damping bar 60, and the spring 20 is compressed, the upper spring seat 40 slides relative to the suspension rod 10 together with the upper bracket 50 and the damping bar 60 clamped therebetween, and the damping bar 60 clamped between the upper spring seat 40 and the upper bracket 50 also rubs with the suspension rod 10 to generate sliding damping.
Preferably, the damping strip 60 of the present invention is made of an elastic material with strong elasticity, a rubber material with a higher damping coefficient can be used, and the damping strip 60 with corresponding specification can be selected as required to meet the requirements of sliding damping. Further, the damping strip 60 may be provided with grease, and at least a portion of the damping strip 60 in frictional contact with the sleeve 32 is coated with grease or lithium-based damping grease, so as to further increase the damping force between the damping strip 60 and the sleeve 32.
In the above-mentioned solution, since the upper spring seat 40 includes the first cylinder 42 and the second cylinder 43 connected up and down, the inner diameter of the first cylinder 42 is larger than the inner diameter of the second cylinder 43, and the inside of the first cylinder 42 forms the accommodating chamber 41, the damping bar 60 is disposed in the accommodating chamber 41, the supporting ring 52 and the damping bar 60 are accommodated in the accommodating chamber 41 from top to bottom, the upper end surface of the damping bar 60 abuts against the lower end surface of the supporting ring 52, the lower end surface of the damping bar 60 abuts against the stepped bottom wall formed between the first cylinder 42 and the second cylinder 43, the damping bar 60 is tightly nested between the suspension rod 10 and the side wall of the first cylinder 42, and the center of the second cylinder 43 is a through hole for the suspension rod 10 to pass through. Therefore, the hanger rod 10 of the present invention is sequentially sleeved with the annular supporting sheet 51, the supporting ring 52, the damping bar 60 and the second cylinder 43 from top to bottom at the position of the upper spring seat 40, as shown in fig. 4, when the spring 20 is compressed, the annular supporting sheet 51, the supporting ring 52, the damping bar 60 and the second cylinder 43 generate friction with the hanger rod 10, and a plurality of components generate force together to generate sliding damping force, so that the shaking and swinging of the washing tub can be effectively reduced, and a better shock absorption effect can be achieved.
In the scheme, the plurality of parts generate force together to generate the sliding damping force, so that the damping force of the suspender assembly is more stably generated, the durability is better, the influence of the ambient temperature, the humidity and the like is smaller, the vibration noise of the washing machine can be effectively reduced, and the user experience of the washing machine is improved.

In the foregoing embodiments of the present invention, the vibration reduction and noise reduction of the washing machine are mainly realized by the vibration reduction of the vibration reduction spring 20 and the damping force generated by the damping bar 60 directly rubbing the suspension rod 10, and the frictional contact area between the damping bar 60 and the suspension rod 10 is small, so that the pressure applied to the suspension rod 10 is large to obtain a large damping force, and the requirements on the materials of the suspension rod 10 and the damping bar 60 are very high, which is not favorable for reducing the cost of the suspension rod assembly.
In this embodiment, the sleeve 32 is sleeved outside the suspension rod 10, the sleeve 32 and the base 31 are integrated to form the lower spring seat 30 for supporting the spring 20, the upper bracket 50, the damping strip 60 and the upper spring seat 40 are sleeved outside the sleeve 32, when the spring 20 is compressed, the upper bracket 50, the upper spring seat 40 and the damping strip 60 clamped therebetween slide relatively to the sleeve 32, so that the friction area between the damping strip 60 and the sleeve 32 is greatly higher than the friction area between the damping strip 60 and the suspension rod 10, the frictional damping force generated between the damping strip 60 and the sleeve 32 is more stable, further, the damping strip 60 of the present invention does not directly rub against the suspension rod 10 to generate the damping force, but rubs against the outer wall of the sleeve 32 to generate the damping force, therefore, the material of the sleeve 32 only needs to be designed as a wear-resistant material, so that the requirement on the material of the suspension rod 10 in the present invention is low, only the sleeve 32 is required to be ensured to have the characteristics of difficult deformation, high surface finish and the like, so that the cost of the suspender component is reduced.
