[0035] figure 1 is a perspective view of a drum type washing machine employing the shock absorber according to the first embodiment of the present invention.

[0036] As shown in the figure, the drum-type washing machine includes a casing 3, a tub 1 for holding water arranged in the casing 3, a drum 2 for accommodating clothes in the tub 1, and a drive motor 10 for rotating the drum 2 at the back of the tub 1. .

[0037] The operation of the drum type washing machine will be described below.

[0038] The rotational force of the driving motor 10 is transmitted to the drum 2 through the belt 11 . When the drum 2 rotates, the clothes placed in the drum 2 rotate together with the drum 2 . At this time, since the drum 2 rotates at a relatively low speed, the clothes rise by the rotating force of the drum, fall down due to gravity, and collide with the water contained in the tub 1 . Through the impact force of clothes and water, the dirt on clothes is washed. Although in this e...

[0062] Figure 7 and Figure 8 A second embodiment of the invention is shown. Particularly, Figure 7 is a sectional view of a shock absorber according to a second embodiment of the present invention, Figure 8 is a sectional view showing the vibration damping operation.

[0063] refer to Figure 7 , the shock absorber 8 of this embodiment is designed to include: a hollow cylinder 261; a rod 262 with one end inserted into the cylinder 261; a sliding rod 267 integrated with one end of the rod 262; A slidable pad support 264 that is installed on the outside of the slide bar 267 and separated therefrom; a vibration damping pad 263 formed on the outer circumference of the pad support 264 makes the frictional force work by friction with the inner circumference of the cylinder 261; , Two springs 265, 266 are respectively connected between the pad support 264 and the rod 262, between the pad support 264 and the slide bar 267. The first and second springs 265 , 266 limit any rel...

Abstract

Disclosed is a damper for a washing machine, comprising: a cylinder; a rod of which one end is inserted in the cylinder; a sliding rod further extending from the inserted end of the rod; a pad holder slidably installed apart from and on an outer side of the sliding rod; a damping pad formed on an outer circumference of the pad holder and being in contact with an inner circumference of the cylinder; and a rotation-preventing part interposed between the pad holder and the rod, for preventing a conical rotation of the washing machine.

Description

technical field [0001] The present invention relates to a shock absorber for a washing machine, in particular to a shock absorber for applying a multi-level shock absorbing force according to the amount of vibration generated by the washing machine. and other vibrations, so the washing machine can be operated reliably with low noise. In addition, the present invention designs a multi-stage shock absorber that sufficiently damps vibrations due to conical rotation generated during operation of the washing machine. Background technique [0002] Generally speaking, washing machines can be divided into drum type, agitator type, and pulsator type according to the washing method. In particular, the drum type washing machine provides a drum with protrusions on the inner wall, and the clothes are brought to a high place by the protrusions along the circumference of the inner wall of the drum, and then fall down, and the washing process is performed by virtue of the resulting impact....
