When a fully automatic washing machine is dehydrating, the uneven distribution of laundry is unavoidable, and high-speed centrifugal dehydration will cause violent vibrations and shaking of the inner and outer drums. For this reason, an elastic support structure that suspends the outer drum on the machine housing is often used to reduce vibration. Specifically, four flexible suspension rods are used to hang the outer drum at the four corners of the machine box.
In fully automatic washing machines, this type of elastic support structure involves a suspension plate fixed at the four upper corners of the casing. The outer drum's suspension ears are connected to the water-holding drum below, with suspension rods passing through both the suspension plate and the outer drum's suspension ears to connect them together. The suspension rods are made of steel wire, with their upper ends attached to a rotatable suspension rod hook head. The lower end of the suspension rod is fitted with a damping cylinder containing shock-absorbing springs and damping rubber bowls. The damping cylinder is hung on the outer drum's suspension ear. It can be seen that the four suspension rods bear the entire weight of the drum body through the damping cylinder, while the weight of the drum compresses the shock-absorbing spring inside the damping cylinder.
During operation, the compression amount of the shock-absorbing spring varies depending on the amount of water in the drum, which also affects the height position of the drum. When vibrations occur during washing or dehydration, the damping cylinder not only swings along the suspension rod hook head but also moves up and down along the suspension rod. This helps absorb vibration energy, reducing the vibration of the washing machine caused by the drum's movement, thus maintaining the overall stability of the machine.
This describes the shock absorption principle of the elastic support structure in Little Swan washing machines.
