Patent ID: 7617693

Claim:
A water purifying system for simultaneously making ice and cold water using one evaporator comprising: means for introducing water purified through filtering means into a cold water tank while controlling the water by the first solenoid valve; means for circulating the water introduced into the cold water tank to a water gutter by a circulation pump; means for circulating the water introduced into the water gutter while it is cooled by an evaporator of ice-making means, whereby cold water is stored in the cold water tank and at the same time an ice-making is conducted by using the cold water as raw water for ice-making; means for rotating the water gutter by an operation of gutter driving means after completion of the ice-making and at the same time introducing refrigerant gas of high temperature and high pressure controlled by the second solenoid valve through a deicing line into the evaporator and deicing; and means for transferring the deiced ice to an ice bin and transferring cold water, which is not made into ice, to the cold water tank, wherein the water of the cold water tank is continuously circulated to the water gutter of an ice-making unit by the circulation pump till water temperature of the cold water tank reaches a value set by a temperature sensor, and then the ice-making is conducted when the water temperature of the cold water tank reaches the set value.
