DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a washing machine in which a washing vessel of the washing machine is oscillated up and down to carry out a washing.
BACKGROUND ART
Generally, in the conventional washing machines, a washing vessel is rotated by the action of a motor, or vanes installed on the bottom of the washing vessel are rotated, thereby washing the articles to be washed.
In such conventional washing machines having the above described structure, when the water in the washing vessel is rotated, the articles to be washed are also rotated. Therefore, the frictions between the washing water and the articles to be washed are very weak, with the result that the washing performance is lowered. In order to solve this problem, the washing vessel or the vanes are rotated in the forward and reverse directions repeatedly so as to produce eddy currents. Thus the frictions between the water and the articles to be washed are increased, so that the washing would be improved, this being the typical conventional method.
The problems of this conventional washing method are such that first the articles to be washed are twisted, and the articles to be washed are entangled with each other. Second, rotation speed of the washing vessel or the vanes is limited (usually 100-400 rpm), and therefore, strong water currents and waves can not be generated, with the result that the cleaning quality is worse than a hand wash. Third, in order to improve the cleaning quality, an auxiliary device such as an air bubble generating device is required. Fourth, the rotating directions for the washing vessel or the vanes have to be reversed from the forward direction to the reverse direction repeatedly.
These problems are common to the washing methods in which water currents are produced through the rotations of the washing vessel or the vanes.
DISCLOSURE OF INVENTION
The present invention is intended to overcome the above described disadvantages of the conventional techniques.
Therefore it is an object of the present invention to provide a washing machine in which a washing vessel containing water and articles to be washed is sealed up, and then the washing vessel is oscillated to make the air within the vessel broken into micro air bubbles, and to make the tiny air pores pass through the articles to be washed so as to clean up the articles to be washed, and in which strong water currents and strong waves are generated to improve the cleaning performance.
It is another object of the present invention to provide a washing machine in which the twisting of the washed articles is maintained to the minimum, and the washing is completed within a short period of time.
In achieving the above objects, the washing machine according to the present invention includes: a case; a washing vessel installed within the case, and having a detachably coupled sealing cap; a shaking means firmly coupled with the bottom of the washing vessel for oscillating the washing vessel; and a balancing means for supporting the shaking means, for absorbing the vibrations, and for maintaining a balance.
