Title: Colloidal silver maker and washing machine having the same
Inventor: LEE YOUNG SU
IPC: D06F35/00
Filed: 2004-04-08
Abstract: A washing machine with a colloidal silver maker is constructed so that there is no water in a silver ion casing when a water supply operation is stopped, thus preventing silver plates from corroding, and preventing impurities from being adhered to the silver plates. The colloidal silver maker includes a silver ion casing, a lid, and a pair of silver plates. An outlet hole is provided on a surface of the silver ion casing to extend from a lower end toward an upper end of the silver ion casing. In this case, the outlet hole has a shape of an ellipse, and is provided so that a height thereof is greater than a width thereof. Further, a height of the silver ion casing and the height of the outlet hole are in a ratio of about 3:2. Such an outlet hole prevents wash water from remaining in the silver ion casing after the water supply operation is stopped, and allows silver ions of a proper concentration to be added to the wash water.
