Automatic ice maker including a secondary water supply for an exterior of an ice mold

A refrigerator appliance comprising:

• a cabinet defining one or more chilled chambers;
• a refrigerant system mounted within the cabinet to selectively cool the one or more chilled chambers, the refrigerant system comprising a compressor and an evaporator in fluid communication with the compressor;
• and
• an ice maker mounted within one of the one or more chilled chambers, the ice maker comprising:
• 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;
• a secondary water supply provided adjacent the exterior surface of the conductive ice mold, wherein the secondary water supply dispenses ice-melting water over the exterior surface of the conductive ice mold:
• and
• a trough provided circumferentially around the exterior surface of the conductive ice mold, the trough comprising a plurality of tabs extending radially inward to contact the exterior surface of the conductive ice mold, wherein the trough is configured to receive the ice-melting water.
