  • Patent number: 11933532
    Abstract: A refrigeration appliance includes a fresh food compartment and a freezer compartment. An ice maker is disposed within the fresh food compartment for freezing water into ice pieces. The ice maker includes a removable ice bin for storing the ice pieces produced by the ice maker. A rotatable auger is positioned within the removable ice bin and configured to drive the ice pieces out of the removable ice bin via a driving force applied in a first direction. A motor is configured to rotate the auger. A drive bar is coupled to the motor and is configured to apply a resisting force to the removable ice bin along a second direction generally opposed to the first direction sufficient to counteract the driving force, wherein the resisting force is less than a removal force applied by a user to remove the removable ice bin from the ice maker.

  • Patent number: 11867445
    Abstract: In a method for controlling an ice maker, a motor rotates an ejector finger relative to an ice tray in a first direction and in a second direction opposite the first direction to discharge ice from the ice tray. When an error condition occurs, the ice maker enters a first error mode, during which an ice maker heater is turned on until the temperature of the ice tray reaches a predetermined temperature or until an ice maker heater error correction time elapses. When the ejector finger is at a home position, the motor rotates in the second direction until the ejector finger is not at the home position or for a first predetermined number of steps, whichever occurs first, and then rotates in the first direction until the ejector finger is at the home position.

  • Patent number: 11846462
    Abstract: A refrigerator includes: a fresh food compartment with an interior wall, an opening, and a door movable between a closed position and an open position for accessing the fresh food compartment via the opening; a cold plate mounted in the interior wall with an evaporator in contact with the cold plate; a chilled component movably mounted on the door adjacent the cold plate, the chilled component includes a heat transfer plate on a side of the chilled component for thermal communication with the cold plate, and a biaser moves the chilled component into thermal communication with the cold plate when the door is closed. The chilled component may be: an ice maker, a liquid/drink cooler, a vegetable cooler, a meat cooler, and/or a wine cooler. The biaser may include the following for moving the chilled component: a spring, an inclined plane, a pulley and weights, and/or a hydraulic piston.

  • Patent number: 11828528
    Abstract: A water dispenser for a refrigerator including a water discharge nozzle fluidly connected to a water source, a valve configured to selectively block the fluid connection, and an actuator operated to allow water to be dispensed. The water discharge nozzle is pivotally mounted to a surface of the refrigerator to pivot between a retracted position and an extended position. In the extended position, the water discharge nozzle is extended outwards beyond the surface of the refrigerator. The water discharge nozzle is biased towards one of the extended and retracted positions. The valve is configured to block the fluid connection between the water discharge nozzle and the water source when the water discharge nozzle is in the retracted position. When the water discharge nozzle pivots to the extended position, the valve is operated to enable fluid connection between the water discharge nozzle and the water source.

  • Patent number: 10837689
    Abstract: A refrigeration appliance includes a fresh food compartment and a freezer compartment. An ice maker with an ice mold is disposed within the fresh food compartment for freezing water into ice pieces. A refrigeration system includes a system evaporator and an ice maker evaporator dedicated to cooling the ice mold. A frame rotatably supports the ice mold within the fresh food compartment between an ice-forming position and an ice-harvesting position. The frame supports the ice maker evaporator at a stationary position that serves as a pivot axis for the ice mold so the ice mold can rotate around the ice maker evaporator between the ice-forming position and the ice-harvesting position, while the ice maker evaporator remains stationary. In one example, a heater is rotatable with the ice mold, and a drip tray is located underneath ice mold and rotatable with the ice mold.
