Refrigerator with Door-Mounted Icemaking System

A refrigerator, comprising:

• a cabinet including one or more food storage compartments defined therein;
• a door coupled to the cabinet adjacent an opening of a first compartment from among the one or more food storage compartments and configured to insulate the first compartment from an exterior environment, the door including one or more interior walls facing the first compartment when the door is closed and an exterior wall facing the exterior environment;
• and
• a door-mounted icemaking system disposed on the door, the door-mounted icemaking system including:
• an icemaking mold disposed between the exterior wall and the one or more interior walls of the door and configured to produce ice;
• an ice storage bin disposed between the exterior wall and the one or more interior walls of the door and configured to receive and store ice produced by the icemaking mold;
• and
• a cold wall evaporator disposed proximate the ice storage bin and along at least one interior wall among the one or more interior walls of the door.

A door-mounted icemaking system for a refrigerator, the refrigerator of the type including a cabinet including one or more food storage compartments defined therein and a door coupled to the cabinet adjacent an opening of a first compartment from among the one or more food storage compartments and configured to insulate the first compartment from an exterior environment, the door including one or more interior walls facing the first compartment when the door is closed and an exterior wall facing the exterior environment, the door-mounted icemaking system including:

• an icemaking mold disposed between the exterior wall and the one or more interior walls of the door and configured to produce ice;
• an ice storage bin disposed between the exterior wall and the one or more interior walls of the door and configured to receive and store ice produced by the icemaking mold;
• an icemaking evaporator disposed between the exterior wall and the one or more interior walls of the door and in thermal contact with the icemaking mold to directly cool the icemaking mold;
• a cold wall evaporator disposed proximate the ice storage bin and along at least one interior wall among the one or more interior walls of the door;
• and
• at least one valve coupled between a refrigerant supply and one or both of the icemaking and cold wall evaporators and configured to regulate refrigerant flow to one or both of the icemaking and cold wall evaporators.
