PROBLEM TO BE SOLVED: To prevent water having a temperature lower than required from being discharged for a long time by properly supplying water from an external water supply source to an ice storage type chilled water supplying device which supplies the chilled water utilizing regenerated heat of ice. ;SOLUTION: In an ice storage type chilled water supplying device comprising two tanks, inner and outer, in which water chilled by an evaporator in the outer tank 21 is introduced into the inner tank 22 through communication holes 22 and the water in the inner tank 22 is delivered from an external water plug 55, when the water level in the inner tank 22 lowers, a water supply valve 30 is opened to supply the water from an external water supply source 32 into the tank. At this point, the relatively high temperature water of the external water supply source 32 naturally drop downward from a water injection port 3 of the water supply valve 30 and the naturally dropping water splashes on a supplied water splashing plate 23 to be directly supplied to the inner tank 22 through the inside of the outer tank 21 and a notch part 25.;COPYRIGHT: (C)1999,JPO
