An ice making assembly may include a conductive ice mold, an insulator ice mold, and an external insulator jacket. The conductive ice mold may extend along a vertical direction between a top conductive mold end and a bottom conductive mold end. The conductive ice mold may define a mold cavity having a vertical opening at the top conductive mold end. The insulator ice mold may be selectively received on the conductive ice mold and cover the vertical opening. The insulator ice mold may define an internal water passage extending above the mold cavity in fluid communication with the mold cavity. The external insulator jacket may be selectively received on the insulator ice mold and cover the internal water passage.

An ice-making water purifier includes a water tank unit, an instantaneous heating device, an extraction member, an ice-maker, a supply pump, an ice-making water inlet passage, an ice-making water supply valve, a flow rate sensor, and a controller configured to control driving of the supply pump and the opening and closing of the ice-making water supply valve such that purified water corresponding to a predetermined supply amount of ice-making water is supplied to the ice-maker on the basis of a flow rate value measured by the flow rate sensor. The controller controls the opening and closing of the channel such that purified water is preferentially supplied to the instantaneous heating device among the instantaneous heating device and the ice-maker.

A refrigerator appliance includes an ice maker provided within a cabinet of the appliance, the ice maker including a plurality of walls forming a receiving space, a conductive ice mold provided within the receiving space, the conductive ice mold defining an internal cavity and an exterior surface, a primary water supply positioned below the conductive ice mold to direct an ice-building spray of water to the conductive ice mold, a heat exchanger disposed on the conductive ice mold to draw heat therefrom, and a secondary water supply provided adjacent the exterior surface of the conductive ice mold. The secondary water supply dispenses ice-melting water over the exterior surface of the conductive ice mold.

An ice maker and a refrigerator having same. The ice maker comprises: a cooling part having a heat dissipation device and a metal piece; a liquid container configured to store liquid; a liquid supply part configured to supply liquid to the liquid container; a moving mechanism configured to rotate and move the liquid container; and a control part. The metal piece is mounted, so that a rod-shaped component made of metal extends downward from a base end to the tip, and the rod-shaped component is cooled by means of the heat dissipation device. The ice-making process is repeated multiple times under the control of the control part, and the following steps are carried out in the ice-making process: a liquid supply step, an ice making step, an avoidance step, a deicing step, and a recovering step. The ice maker can make ice within a short period of time.

A method of making clear ice includes circulating a refrigerant through a refrigerant loop. A portion of the refrigerant loop is in contact with a mold body. Thus, the refrigerant chills the mold body. The method also includes spraying a first volume of liquid water into a mold cavity of the mold body. As a result, a first volume of ice is formed in the mold cavity. The method also includes spraying a second volume of liquid water into the mold cavity after the first volume of ice has formed. Thus, a portion of the first volume of ice is melted and a second volume of ice is formed in mold cavity. The clear ice includes an unmelted portion of the first volume of ice and the second volume of ice.

A water purifier includes a water purification unit, and an ice making unit. The water purification unit includes: a water filter for filtering introduced raw water to provide the purified water and unfiltered living water; a purified water tank including a first storage for storing unfiltered water, a second storage for storing the purified water discharged from the water filter, and a separation membrane formed of an impermeable material which independently partitions the first storage and the second storage and has elasticity, wherein the second storage shrinks when the first storage expands, and the first storage shrinks when the second storage expands; a flow channel connecting the water filter, the purified water tank, and the ice making unit to provide a passage through which the raw water, the living water, and the purified water flow; and a valve unit including a plurality of valve modules.
