  • Patent number: 11326822
    Abstract: An ice making system for creating clear ice and an associated method are provided. The ice making system employs a first sealed refrigerant system connected to a heat exchanger. A second sealed refrigerant system is also connected to the heat exchanger for cooling a first refrigerant of the first sealed refrigerant system. A heat exchanger heater is at least partially contained with the heat exchanger for heating the first refrigerant. A pump in the first refrigerant system is activated after heat exchanger heater has warmed the first refrigerant, enabling a cooling cycle to begin. Once sufficient clear ice has been generated, the pump is deactivated.

    Abstract: An apparatus and a method for driving an icemaker for making ice cubes in a refrigerator. An ice-full state is sensed in such a way as to rotate an ejector and a cam gear in a reverse direction (opposite to an ice-ejecting direction), thereby preventing interference with the ice cubes present in the icemaker and thus enabling the ice-full state to be accurately sensed. A first torsion spring is mounted to an intermediate gear with a small rotation angle ratio to allow only a minimum amount of torque to be transferred to other components such as an ice-detecting lever, thereby increasing the durability of the components and providing a precise rotation force. The axial center of rotation of a second torsion spring is defined at a position that faces the other end (the revolving end) of the ice-detecting lever, to allow a minimum moment to be substantially constantly applied.

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.

    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: 20140311178
    Abstract: Embodiments generally relate to methods and apparatuses for generating ice. In one embodiment, a material is introduced to water, and the temperature of the combination of the water and the material is lowered until ice forms, the formed ice having a higher albedo than it would have had if the step of lowering the temperature had been carried out on the water without first carrying out the step of introducing the material. In one embodiment, the material is selected such that an aqueous solution of the material is alkaline. In another embodiment, a material is introduced to water, and the temperature of the combination of the water and the material is lowered until ice forms, the ice forming at a faster rate than the rate at which it would have formed if the material had not been introduced to the water.

  • Publication number: 20140260349
    Abstract: A novel control logic for an individual cube spray type ice machine. The duration of the freeze cycle is able to adapt to changes in inlet water temperature, changes in ambient air temperature, and the impact of warm temperatures of internal ice making parts within the ice machine due to off cycle periods. This is accomplished through a combination of starting a freeze time period only after the water temperature for the volume of water circulating over the evaporator has reached approximately 32° F., and a freeze time period value that is a function of the refrigerant temperature leaving the condenser at the time where the water reaches approximately 32° F.

  • Publication number: 20140261132
    Abstract: Systems and methods for storing energy in gaseous form in submerged thin-walled tanks are secured to the ocean or lake floor but are open to the water at the tank bottoms and are configured to be filled with gas while submerged. A conduit operatively connected to the tanks provides flow from a surface source of an energy-containing gas to the tank interiors. Surface or subsurface pumping apparatus which may include piston-less pressure cylinders or have leveraged pistons provide a preselected flow rate of the energy-containing gas into the containment structure interior against a back pressure essentially equal to the static pressure of the body of water at the location of the tank to displace an equivalent volume of water through the open bottom. The conduit can be configured to allow heat transfer to vaporize liquefied gas prior to storage. Hydrogen gas can be generated and stored within the tank using Aluminum activated with Galinstan.

  • Publication number: 20140238053
    Abstract: An 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 drain aperture in fluid communication with a fluid reservoir. Ice forming members extend from an ice forming evaporator into respective fluid channels. During an ice making event, fluid continuously supplied to the upper fluid chamber flows into each of the fluid channels and out through at least one drain aperture into a fluid reservoir below. The ice forming members are cooled such that fluid flowing across the fluid channels freezes on the ice forming members over time, forming clear ice pieces. The ice pieces are subsequently released from the ice forming members and transferred for storage and/or dispensing.

  • Patent number: 8800305
    Abstract: A retrofit ice making and bagging apparatus and retrofit installation method provide automatic supply of bags of ice into a freezer compartment. The apparatus has an outer housing with a lower end configured for securing on top of an aisle freezer so that openings in the lower end of the housing and upper end of the freezer are aligned to provide a passageway into the freezer compartment. An ice making unit and bag making and filling station are mounted in the housing. Ice is transported from the ice making station into partially formed bags at the bag making and filling station, and a bag is sealed and separated when a sufficient amount of ice is supplied to the bag. The bag making and filling station communicates with the passageway into a storage compartment in the freezer, whereby separated bags of ice fall into the storage compartment on completion.
