Abstract:
A feed device having a function of sustained release for a mixing solution, said feed device comprising:a feed body including an inlet, an outlet and a supply channel defined between the inlet and the outlet; a solution holding chamber for holding a mixing solution to be mixed with water flowing in the supply channel; a dilution chamber, which communicates with said solution holding chamber to guide the mixing solution from said solution holding chamber, and which includes a sustained release outlet, such that the dilution chamber introduces therein a part of the water flowing in the supply channel through the sustained release outlet, dilutes the mixing solution with the introduced water into a lower concentration solution, and feeds the lower concentration solution through the sustained release outlet to the supply channel; and a partition plate for partitioning said solution holding chamber and said dilution chamber, wherein said partition plate allows the mixing solution to permeate between said chambers mutually.
