Specifically, in addition to using the spring damping assembly 2 for shock absorption, the suspension rod assembly for the washing machine in this embodiment also cooperates with the magnetic force generated by the magnetic force assembly 3. The repulsive force cooperates with the elastic force generated by the spring 22 to obtain a better damping effect. Preferably, the first magnet 31 and the second magnet 32 are annular structures, and the outer diameter of the first magnet 31 is smaller than the inner diameter of the second magnet 32, so that during the movement of the second magnet 32, the first The second magnet 32 can be sleeved on the outside of the first magnet 31 and move within the upper and lower range of the first magnet 31 . The details are as follows: when the dehydration is started, because the clothes of the washing machine have a large water content and a large load, the first magnet 31 is located in the ring of the second magnet 32, the magnetic force assembly 3 does not provide stiffness, and the stiffness of the suspension rod 1 is completely provided by the spring 22, and the spring 22 The high rigidity allows the washing machine to start smoothly. As the speed of the washing machine increases, the moisture content of the clothes becomes lower and lower. During the high-speed dehydration process, the moisture content of the clothes is low, and the first magnet 31 and the second magnet 32 separate. A repulsive force is generated between the second magnets 32 to provide negative stiffness, which is superimposed with the stiffness of the spring 22 to reduce overall stiffness of the boom 1 and reduce vibration and noise of high-speed dehydration.

Wherein, there can be multiple ways for the installation position of the second magnet 32, for example: the second magnet 32 can be directly installed on the inner cylinder of the wave-wheel washing machine, and the second magnet 32 on the inner cylinder can be Move relative to the suspension rod 1; preferably, the second magnet 32 is arranged on the upper bracket 21, and when assembling the wave-wheel washing machine, the upper end of the suspension rod 1 is installed on the casing of the wave-wheel washing machine, while the inner cylinder is installed On the upper support 21, there is a suspender 1 to hoist the inner cylinder in the box shell. After the second magnet 32 is installed on the upper support 21, the inner cylinder moves up and down to make the upper support 21 and the second magnet 32 move together, thereby realizing The second magnet 32 moves relative to the suspender 1 , and the distance between the first magnet 31 and the second magnet 32 on the suspender 1 will change, so that the magnetic force on the suspender 1 is different. Further, in order to facilitate the installation of the second magnet 32, the upper holder 21 is provided with a sleeve 24, the spring 22 and the lower holder 23 are all arranged in the sleeve 24, and the second magnet 32 is arranged on the sleeve 24. on the sleeve 24. Specifically, the sleeve 24 wraps the spring 22 and the lower bracket 23, and the second magnet 32 is installed at the lower part of the sleeve 24, and the first magnet 31 is also arranged in the sleeve 24, so that the spring and the magnetic force assembly 3 are all arranged in the sleeve 24 for protection, improving reliability in use. Further, the port of the sleeve 24 is also provided with an end cap 241 , through which the relevant components are enclosed in the closed space formed by the sleeve 24 and the end cap 241 .

The two stiffnesses are superimposed, so that the boom has a large static stiffness and a small dynamic stiffness. During the start-up stage of the pulsator washing machine, the boom’s The static rigidity is relatively large, which can reduce the possibility of the inner cylinder colliding with the box. In the high-speed dehydration stage, the dynamic rigidity of the boom is small, the vibration isolation rate becomes larger, the transmission of vibration is reduced, and the noise is reduced; at the same time, the connection between the two magnets There is no physical contact between them, and no friction noise will be generated, thereby reducing noise, improving the shock absorption performance of the suspension rod assembly for the washing machine, and improving the reliability and user experience of the pulsator washing machine.
