Benefits of technology

[0022]Therefore, it is a first object of the present invention to provide a washing machine capable of preventing an outer tub inclined towards a driving unit from colliding with a casing at the time of an initial vibration occurrence, by supporting the outer tub by installing suspensions having a relatively large damping force at one side where a large load occurs due to the driving unit, etc., and by installing suspensions having a relatively small damping force at another side facing the one side.
[0023]It is a second object of the present invention to provide a washing machine capable of preventing an outer tub from colliding with a casing by installing suspensions having a large damping force at a side of a driving unit by mounting a base cap to a lower opening of a damper cap, in which a small amount of air leakage occurs even if an air gap between the damper cap and the damper base is widened.
[0024]It is a third object of the present invention to provide a washing machine capable of absorbing excessive vibration occurring at a side having a large initial deflection due to a load of a driving unit, by asymmetrically arranging suspensions to each other.

Abstract

Disclosed is a washing machine. In order to reduce excessive vibration, the washing machine is provided with suspensions between a casing and an outer tub, in which a suspension positioned at one side of the casing and a suspension facing the suspension positioned at one side of the casing are installed so that their damping forces can be asymmetric to each other. Accordingly, even if excessive vibration occurs at the time of an initial dehydration process, the outer tub inclined to a driving unit is prevented from colliding with the casing.

Description

RELATED APPLICATION[0001]The present invention relates to subject matter contained in priority Korean Application No. 10-2007-0076580, filed on Jul. 30, 2007, which is herein expressly incorporated by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a washing machine, and more particularly, to a washing machine capable of preventing an outer tub inclined toward a driving unit from colliding with an external casing at the time of an initial vibration occurrence, and capable of effectively reducing excessive vibration by asymmetrically installing suspensions, in which the outer tub is supported by installing suspensions having a relatively large damping force at a side where a large load occurs due to the driving unit, etc.[0004]2. Description of the Background Art[0005]Generally, a washing machine serves to wash laundry by using a softening process by detergent, a frictional process by water stream occurring as...
