Problems solved by technology

[0011] However, due to the existing shock absorber, if the friction force generated by the friction member is set larger, the friction member will not rub against the inner peripheral surface of the cylinder 20, and no damping force will be generated.
Then, the vibration of the washing tub is transmitted to the casing, increasing the noise and vibration of the

Abstract

A damper includes: a cylinder; a piston rod disposed to be movable linearly in the cylinder; and a plurality of damping members installed between the cylinder and the piston rod, and generating a damping force by multi-stage so that when a vibration transmitted from the cylinder to the piston rod or from the piston rod to the cylinder is big, a strong damping force is generated, whereas when a vibration is small, a weak damping force is generated. A damping force is generated by stages depending on a displacement of a vibration transferred from the cylinder to the piston or from the piston to the cylinder. If a small amount of vibration is transferred, a weak damping force is generated, whereas if a large amount of vibration is transferred, a strong damping force is generated. Accordingly, a vibration damping performance can be improved.

Description

technical field [0001] The present invention relates to a shock absorber for a washing machine, and more specifically, relates to a shock absorber capable of enhancing the shock absorbing ability. The enhanced shock absorber is realized by applying a strong damping force when the vibration is severe and a weak damping force when the vibration is small ability. Background technique [0002] figure 1 It is a sectional view of an ordinary front-loading washing machine. [0003] Such as figure 1 As shown, a common drum type washing machine includes a shell 2 constituting its exterior, a washing tub 4 that is arranged in the shell 2 and stores washing water, and a drum that is rotatably arranged in the washing tub 4 and performs washing and dehydration operations on clothes. 6, and a drive motor 10 arranged on the rear side of the washing tub 4, the drive motor 10 is connected to the drum 6 through a drive shaft 8 so as to rotate the drum 6. [0004] An inlet 12 is formed at ...
