PURPOSE: A chemical liquid injection device of a water supply control system is provided to remove residual liquid with lime residue cleanly remaining in a dissolution hopper by opening an outlet of the hopper after supplying the constant amount of liquid to a water tank. CONSTITUTION: A chemical liquid injection device(100) of a water supply control system includes a main body(110), a water tank(120), a chemical supply motor(130), a water supply motor(140), a chemical input guide(160), and an opening and closing valve(170). The water tank manufactures chemical liquid by dissolving a chemical(A). The water tank is prepared in an inner side of the main body. The water supply motor supplies water for dissolving the chemical. The chemical supply motor supplies the liquid produced in the water tank. A chemical dissolution hopper is connected with the water tank. A drain(151) is formed on the center of the chemical dissolution hopper. The chemical dissolution hopper is installed at the bottom of the water tank. The chemical input guide is installed between an inlet of the chemical formed on the top of the main body and the chemical dissolution hopper. The opening and closing valve is installed at the drain of the chemical dissolution hopper. |
