  • Patent number: 8950197
    Abstract: A clear ice making system and method utilizes an ice forming tray pivotally connected to opposing side walls of an icemaker housing. Ice forming fingers of a dedicated evaporator extend into fluid within the ice forming tray, and are cooled by communication with the refrigerant circulating system of the refrigerator. A motor oscillates the ice forming tray about a longitudinal axis at a frequency of about 0.4-0.6 hertz as fluid channels freezes on the ice forming fingers over time, forming clear ice pieces. During an ice dispensing event, the motor pivots the ice making tray about the longitudinal axis such that fluid remaining within the ice making tray drains into a fluid reservoir below. The ice forming fingers are then heated to release the clear ice pieces for transfer from the fresh food compartment to the freezer compartment of the refrigerator.

  • Publication number: 20150000311
    Abstract: A refrigerator includes a fast ice making device for quickly producing ice cubes. The fast ice making device includes a mold body having a plurality of ice forming cavities adapted to hold fluid. In an ice making cycle, a vacuum system evacuates air from the cavities, thereby depressurizing the cavities. Then, a liquid delivery system delivers liquid to the depressurized cavities, whereby an initial portion of the liquid bubbles up within the respective cavities. Overall, a cooler fluid is established at the beginning of an ice making cycle, thus accelerating the rate at which ice cubes are formed within the fast ice making device. Once ice cubes have been formed within the cavities, a heat transfer system is utilized to heat the cavities, thereby slightly melting the ice cubes and aiding in the expulsion of ice cubes from the cavities.

    Abstract: An icemaker control module for controlling an icemaker making ice bodies in a freezer has a base with snap fit components including an insert molded circuit board, a motor assembly, an ice level sensing system using a bail arm or a paddle, and a water fill system. Lance features in the circuit board connect switch and motor leads. The thermostat, ground wire, and heater of the icemaker electrically couple to the insert molded circuit board when the ice maker control module is joined to the ice maker. Energy may be conserved by pausing rotation and turning off the heater. There is a method for manufacturing the insert molded circuit board in a cell.

  • Publication number: 20110265498
    Abstract: A refrigerator is provided that includes an apparatus for producing ice comprising a reservoir that contains water, at least one freezing member, a power source, and at least one fin located on the reservoir. The at least one freezing member is located at least partially in the reservoir. The at least one freezing member is configured for forming ice by freezing the water along the periphery of the at least one freezing member. The power source is configured to move the reservoir to create a movement of the water about the at least one freezing member. The at least one fin located on the reservoir is configured for enhancing the movement of the water about the at least one freezing member and for restricting a splashing of water from the reservoir.

  • Publication number: 20110219789
    Abstract: A refrigerator includes a fast ice making device for quickly producing ice cubes. The fast ice making device includes a mold body having a plurality of ice forming cavities adapted to hold fluid. In an ice making cycle, a vacuum system evacuates air from the cavities, thereby depressurizing the cavities. Then, a liquid delivery system delivers liquid to the depressurized cavities, whereby an initial portion of the liquid bubbles up within the respective cavities. Overall, a cooler fluid is established at the beginning of an ice making cycle, thus accelerating the rate at which ice cubes are formed within the fast ice making device. Once ice cubes have been formed within the cavities, a heat transfer system is utilized to heat the cavities, thereby slightly melting the ice cubes and aiding in the expulsion of ice cubes from the cavities.

  • Publication number: 20100218520
    Abstract: Provided is an ice maker including a mold with two or more cavities for receiving water to be frozen into ice pieces. A bracket defines a track establishing a range of travel of the mold during an ice making cycle and a removable pin projects outwardly from the mold, extending into the track defined by the bracket to support the mold within the ice maker. The mold can be provided with a partition separating the cavities, the partition including an aperture for establishing a substantially-even water level in the cavities below the partitions.

  • Publication number: 20100218519
    Abstract: A refrigeration system is provided with an ice maker chamber within a fresh food compartment. The refrigeration system includes a refrigeration path and an ice maker path. The ice maker path includes an electronic expansion valve for controlling the refrigerant entering an ice maker evaporator and an evaporator pressure regulator. Controlling the refrigeration system includes the steps of sensing a first refrigerant temperature at an exit of the ice maker evaporator and controlling a first control of the electronic expansion valve until the temperature reaches a temperature target. The method of controlling can further include comparing a slope of the temperature to at least one of a minimum, a target, or a maximum setting to adjust the control. Subsequently, a second control for the electronic expansion valve can be repeatedly adjusted by evaluating the first refrigerant temperature and the slope.

    Abstract: The present invention relates to a supercooling method and a supercooling apparatus which can maintain an object in a supercooled state. According to the present invention, a supercooling method includes a first cooling step of cooling a stored object toward a cooling temperature below a phase transition temperature thereof, a step of judging whether the stored object is released from a supercooled state in the first cooling step, a step of thawing the stored object when the stored object is released from the supercooled state, and a second cooling step of cooling the stored object toward a cooling temperature below zero that is higher than the lowest temperature of the stored object before the release of the supercooled state, wherein the first cooling step is continuously performed when the object is maintained in the supercooled state.
