Abstract
A washing machine comprising a tub, a water supply unit for supplying water to the tub and a silver solution supply device for supplying a silver solution to the tub, wherein the silver solution supply device includes a housing provided with an inlet and an outlet, a water feed unit for connecting the inlet of the housing and the water supply unit of the washing machine, two silver members installed in the housing and ionized by the electrolysis, and a current speed reduction member positioned between an end of the silver member located at the outlet and the outlet of the housing. The current speed reduction member reduces the current speed of the wash water supplied to the silver solution supply device and changes the current of the wash water, thereby allowing the silver members to be sufficiently ionized and providing sufficient antibiotic and bactericidal effects.
