  • Publication number: 20150107276
    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: The present invention concerns a freezer segment for a freezer of the type used for casting confectionery in molds which are cooled for freezing and subsequently supplied with heat for a short period, whereafter stripping occurs. Cooling of the molds is effected by using direct evaporation of CO2. The advantage of such a freezer segment is that there is no use for both a primary and a secondary cooling circuit. Another advantage in using a system according to the invention is that working with temperatures down to about minus 50° C. is enabled, compared to about minus 40° C. with brine systems. The low freezing temperature entails that the capacity of a given system is increased by about 40%.

  • Patent number: 8555658
    Abstract: An ice maker, a refrigerator including the ice maker, and an ice making method are provided. The ice maker includes a tray having a predetermined length and to which water is supplied to make ice. The ice maker is configured to mechanically separate the ice from the tray by using pistons which are driven by being pressed by structures. This allows the ice maker to have a reduced size, and a small occupation area, thereby implementing a slim configuration of a refrigerator. Furthermore, since an installation height of the ice maker is lowered, a path for supplying cool air may be shortened. This may prevent loss of cool air being supplied to the ice making chamber. Since the ice maker has a simplified configuration and precise operation controls, the fabrication costs may be reduced, and inferiority of the ice maker due to malfunctions may be prevented.

  • Publication number: 20130199215
    Abstract: Methods of manufacturing a frozen food product in a chamber having a tubular refrigerated wall and a partition which is movable along the chamber between upper and lower positions include multiple steps. First, after positioning the partition at its upper position, a liquid food product mix is introduced into the chamber above the partition so that the mix forms a pool of a selected depth atop the partition. The partition is then moved downward towards its lower position at a selected rate which causes the mix in the pool to flow outward under gravity into contact with the wall where it at least partially freezes to form an adherent uniform frozen mix layer on progressively lower segments of that wall. Then, the frozen mix layer is scraped from the wall to form a multiplicity of frozen scrapings, which are collected in a receptacle and dispensed as a frozen food product.

  • Patent number: 8413457
    Abstract: Disclosed are a refrigerator and a control method thereof, wherein operation of an icemaker can be controlled according to time or function. A sleep mode to control operation of an icemaker according to time is set to prevent generation of noise due to an ice-separating operation implemented at night. In the setting of the sleep mode, a control range of the sleep mode is selected according to a desired operating function (ice-making function or ice-separating function) of the icemaker and also, a period of the sleep mode in units of days/weeks/months (or an operating term) is selected.

  • Publication number: 20120324917
    Abstract: A clear ice making assembly and method utilizes a housing having an upper fluid chamber, a plurality of distinct, substantially vertical fluid channels, and at least one fluid outlet aperture in fluid communication with a bottom fluid chamber. During an ice making event, portions of an ice forming evaporator extending through the housing are exposed to water flowing into the fluid channels from the upper fluid chamber. The ice forming evaporator is formed with microchannels through which refrigerant flows such that water flowing across the fluid channels freezes on the exposed portions of the ice forming evaporator over time, forming clear ice pieces. In a harvesting operation, the ice pieces are released from the ice forming evaporator and transferred for storage and/or dispensing.

  • Publication number: 20120318003
    Abstract: Disclosed are an ice maker, a refrigerator having the ice maker, and a method for supplying ice of the refrigerator. When the ice making container is rotated, ice of the ice making container freefalls to be released, thus reducing the size of the ice maker and making a refrigerator slimmer. Also, since a partition wall is not provided on an inner circumferential surface of the ice making container, the roughness of the inner circumferential surface of the ice making container can be enhanced, and accordingly, heat can be evenly transferred from an ice releasing heater to reduce a generation amount of residual water. In addition, since ice can be released without using the ice releasing heater, power consumption can be reduced and residual water which can be generated in case of using the heater can be further reduced.
