Abstract: An ice maker having a refrigerant preheating unit and a control method thereof are disclosed. The ice maker having a refrigerant preheating unit according to one aspect of the present invention and a control method thereof may include: a compressor for compressing a refrigerant; a condenser for condensing a refrigerant discharged from a discharge end of the compressor; an expansion unit for expanding a refrigerant condensed in the condenser; an ice-making evaporator for evaporating a refrigerant expanded in the expansion unit to make ice; a refrigerant flow path unit for guiding a refrigerant discharged from the compressor to a suction end of the compressor through the condenser, the expansion unit and the ice-making evaporator; an ice-removing refrigerant flow path unit for guiding a refrigerant discharged from the compressor to the ice-making evaporator; a refrigerant preheating unit for causing a refrigerant discharged from the compressor to be re-suctioned into the compressor before passing through the condenser; and a control unit for controlling the refrigerant preheating unit.

Abstract: The present invention relates to a running-water-type evaporator, and an ice-making device and a water purification device comprising the same, and to a running-water-type evaporator, and an ice-making device and a water purification device comprising the same, the evaporator uniformly transferring, to ice, heat supplied through high-temperature fluid during ice separation, so as to enable the ice to be easily separated without using separate ice-separating water, and thus minimizes melting of the ice during ice separation, and circulating ice-making water in a state where the ice-making water flows only toward the outer sides of a pair of outer plate members, and thus a degradation in the cleanliness of the ice-making water can be prevented.
