  • Publication number: 20230332816
    Abstract: A refrigerator appliance may include a cabinet, a liner, a thermodynamic assembly, an air conduit, a heat exchange (HE) sleeve, a conductive ice mold, and a water dispenser. The liner may define an icebox (IB) compartment. The air conduit may be disposed within the IB compartment to define a conduit path between a conduit inlet and a conduit outlet downstream from the conduit inlet. The heat exchange (HE) sleeve may be disposed along the air conduit between the conduit inlet and the conduit outlet. The HE sleeve may include a conductive panel extending across the conduit path. The conductive ice mold may be mounted to the HE sleeve within the IB compartment. The conductive ice mold may define a mold cavity outside of the air conduit. The water dispenser may be positioned below the conductive ice mold to direct an ice-building spray of water to the mold cavity.

  • Patent number: 11662129
    Abstract: An icemaker appliance and a method for making clear ice are provided. The icemaking apparatus includes a cabinet forming an ice storage compartment. A reservoir is provided within the ice storage compartment. A liquid supply conduit is configured to supply liquid to the reservoir. An ice mold is configured to freeze liquid at the ice mold. A nozzle is configured to dispense the liquid from the reservoir to the ice mold. A controller is configured to execute instructions that perform operations. The operations include dispensing, from a body of liquid at the reservoir, a flow of liquid toward the ice mold; freezing, at the ice mold, a first portion of the flow of liquid received from dispensing the flow of liquid to the ice mold; providing, to the reservoir, a second portion of the flow of liquid dispensed toward the ice mold; and providing, from the liquid supply conduit to the reservoir, a supply of liquid after dispensing the flow of liquid toward the ice mold.
