Embodiment Construction

[0044] Preferred embodiments of the present invention will now be described in detail with reference to examples shown in the accompanying drawings.

[0045] The principle of the washing machine with vibration damping will be described with reference to FIGS. 4 and 5 .

[0046] In order to seek the most effective vibration reduction method, the inventors have conducted research on numerous vibration reduction methods. As a result, among many factors such as the shock absorber, the material, thickness, and shape of the case, the material of the foot pad, etc., it can be found that the optimization of the foot pad is the most effective for attenuating the vibration. The results of tests verifying that the correct design of the foot pads are the most effective for damping vibrations are shown in Figures 4 and 5.

[0047] Graphs shown in FIGS. 4 and 5 illustrate the principle and effect of a washing machine with vibration damping according to a preferred embodiment of the present...

Abstract

Washing machine including a cabinet forming an outside shape of the washing machine, legs fitted to a bottom of the cabinet for supporting the cabinet, and leg pads joined to an underside of the legs respectively for attenuating vibration taken place when the washing machine is operated, wherein the leg pad is formed of block copolymer of hard blocks and soft blocks, thereby attenuating vibration.

Description

[0001] This application claims priority from Korean applications No. P2003-0024734 filed on April 18, 2003, No. P2003-0060269 filed on August 29, 2003, and Korean application No. P2003-0060270 filed on August 29, 2003, Its contents are hereby incorporated by reference. technical field [0002] The invention relates to a washing machine, in particular to a washing machine capable of effectively reducing vibration when the washing machine is running. Background technique [0003] Washing machines that remove contaminants from laundry by applying energy such as impact are classified into a pulsator type washing machine, a drum type washing machine, and an agitator type washing machine according to a method of applying energy to the laundry. The drum type washing machine mainly drops and hits the laundry by rotating the drum, and adds detergent therein to complete the washing. The pulsator or agitator type washing machine hits the laundry by rotating a pulsator or agitator conn...
