Adjustable damping suspender for pulsator washing machine and pulsator washing machine having the same

Abstract

The invention provides an adjustable damping hanger rod applied to a pulsator washing machine and the pulsator washing machine provided with the adjustable damping hanger rod. The adjustable damping hanger rod comprises a cylinder body, a long hanger rod, a piston and a top mounting seat, wherein the long hanger rod penetrates through the cylinder body along the axial direction and can do reciprocating motion relative to the cylinder body and along the axial direction; the piston is fixedly arranged on the long hanger rod inside the cylinder body in a sleeved mode; the piston is provided with a coil and a liquid flowing passage, wherein the coil is used for generating a magnetic field when power is on, and the liquid flowing passage penetrates through the piston along the axial direction so that the fluidity of magnetorheological fluid in the liquid flowing passage can be changed by changing the value of the current in the coil; and the top mounting seat is arranged at the top end of the long hanger rod in order to hang the adjustable damping hanger rod on a hanging holder arranged at the top of a shell of the pulsator washing machine, wherein a positioning part extending upwards is formed at the upper end of the cylinder body and is matched with a shock absorbing seat arranged at the circumferential wall of the lower part of a washing outer cylinder of the pulsator washing machine so that the washing outer cylinder can be hung on the adjustable damping hanger rod under the effect of the gravity. The adjustable damping hanger rod provided by the invention is especially applicable to the pulsator washing machine.

Description

technical field [0001] The invention relates to a shock absorbing device, in particular to an adjustable damping suspender for a wave-wheel washing machine and a wave-wheel washing machine with the same. Background technique [0002] As we all know, during the working process of the washing machine, due to the eccentric load and centrifugal force of the washing items, it is inevitable to generate vibration. The damping device generally used in the current pulsator washing machine is an adjustable damping suspender connected to the shell of the washing machine and the washing tub, mainly through the up and down movement of the friction parts on the adjustable damping suspender to form sliding friction and generate friction to reduce the vibration. Shock effect. The disadvantage of this structure is that regardless of the amount of laundry, the obtained frictional force is almost constant, and the change and adjustment of damping cannot be realized.
