Problems solved by technology

[0004] However, the related art washing machine has a problem in that an increase in the size of the outer tub causes an excessive increase in weight, so that it is not easy to allow the outer tub to have a large capacity.
Also, since the rigidity decreases when the inner tub rotates at high speed, the weight of the outer tub increases causing the inner tub and the outer tub to collide
Therefore, the rotation speed of the inner tub must be lowered as necessary to avoid the collision of the inner tub and the outer tub, however, this disadvantageously causes a decrease in cleaning performance.

Abstract

A washing machine includes: a cabinet forming an external appearance; an outer tub hanging within the cabinet and having an open upper portion allowing the clothes to enter therethrough, and allowing washing water to be put therein; and an inner tub disposed within the outer tub and rotating based on a vertical shaft, wherein the outer tub includes: a base through which a driving shaft rotating the inner tub; and a side wall part extending upward from the base to form a side wall of the outer tub and having a lower portion thicker than an upper portion thereof. The increase in weight according to an increase in capacity can be reduced and a loss of rigidity can be minimized. Also, because the center of gravity is removed to a lower side, stability with respect to vibrations can be obtained.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2009-0029135 filed on Apr. 3, 2009 at the Korean Intellectual Property Office, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to a washing machine, and more particularly, to a washing machine having a structure in which the lower portion of the side wall of the outer tub is thicker than the lower portion of the side wall of the outer tub, the washing machine has a large capacity and is improved with regard to vibration stability. Background technique [0003] Washing machine generally refers to: various devices for treating clothes by applying physical and chemical actions to clothes, such as by using chemical decomposition operations between water and detergent and physical operations such as between water and clothes Laundry treating machines for separating pollutants from clothes, bedding, etc. (hereinafter refe...
