Abstract:
An ice maker, including sensors to measure usage parameters and transmit the same to a controller. The controller is operably connected to a plurality of ice forming systems, and directs the systems to operate in a high energy mode or a low energy mode, based on the usage parameter. The usage parameters may include an ice level, a change in the ice level over time, the amount of time that a dispenser is actuated, the time of day, or historical usage patterns. The ice forming systems may include one or more of a thermoelectric device coupled to a bottom surface of an ice forming plate, a forced air system to circulate cold air, a forced air system to circulate warm air, and a temperature control system to maintain a temperature gradient between a first chamber above the ice forming plate and a second chamber below the ice forming plate.
Abstract:
A bottom mount refrigerator is provided including a thermal battery or phase change material positioned within the refrigerator or freezer in order to increase energy efficiency and compartment sizes of the refrigerator. The thermal battery can be used with an ice maker to aid in removing heat from the water in the ice maker to produce ice. Furthermore, the phase change material or thermal battery may be used with a thermoelectric cooler to aid in ice production. The phase change material may be tuned to various temperatures according to the desired use of the phase change material, as well as the location of the thermal battery or phase change material. Other embodiments include positioning the phase change material in the liner of the compartments or in thermal storage units in order to further increase the energy efficiency of the refrigerator.
Abstract:
A refrigerator includes a refrigerator cabinet, a fresh food compartment disposed within the refrigerator cabinet, a freezer compartment disposed within the refrigerator cabinet below the fresh food compartment, and first and second French doors operatively connected to the refrigerator cabinet to provide access to the fresh food compartment. There is also a mullion between the fresh food compartment and the freezer compartment, an air inlet and an air outlet proximate a bottom of the first French door, and an air outlet and an air inlet on a front face of the mullion. When the first French door is in a closed position, the air inlet proximate the bottom of the first French door aligns with the air outlet on the front face of the mullion and the air outlet proximate the bottom of the first French door aligns with the air inlet on the front face of the mullion.
Abstract:
A method of making an ice structure comprising the steps of: providing a mold with at least two mold portions where the at least two mold portions come together to form a cavity that defines a shape of an ice structure; placing the at least two mold portions in thermal communication with at least one cooling source; chilling the at least two mold portions using the at least one cooling source; orienting the at least two mold portions in spaced apart relation; delivering a flow of water such that the flow of water passes along the surface of the at least two mold portions with the mold segments such that water flows (by capillary/wicking action) over the mold segment and forms an ice structure segment; ceasing the flow of water when the ice structure segments are formed; and fusing the ice structure segments together to form the ice structure.
Abstract:
An ice maker having an ice tray horizontally suspended within a housing and a drive body rotatably coupled to a transverse axis of the ice tray and configured to oscillate the ice tray about the transverse axis. The cold side of a thermoelectric device is thermally coupled with a bottom surface of the ice tray, and a hot side opposes the cold side. A barrier extends around the periphery of the ice tray within the housing, and separates the housing into a first chamber and a second air chamber. A heat sink is thermally coupled with the hot side of the thermoelectric device and extends into the second air chamber. An intake duct member is coupled with the housing proximate the second air chamber, and is configured to dispense a cold air flow over the heat sink. The barrier restricts the cold air flow from entering the first chamber.
Abstract:
A refrigerator may include a refrigerator cabinet in at least one enclosure that can be mounted in different locations within the cabinet. The enclosure also can have targeted, independently controlled temperature provided to it. This allows the refrigerator to be highly customizable and reconfigurable according to desire or need. For example, an ice maker ice bin can be mounted in different positions within the cabinet, including door mount, refrigerated food compartment mount or freezer mount. Alternatively, specialized enclosures for such things as can chilling, milk chilling, meat chilling, or even thawing can be placed in multiple locations in the cabinet according to need or desire.
Abstract:
A refrigerator that has a fresh food compartment, a freezer compartment, and a door that provides access to the fresh food compartment is disclosed. An icemaker is mounted remotely from the freezer compartment. The icemaker includes an ice mold with an icemaking cycle having a liquid to ice phase change. A thermoelectric device has a cold side and a warm side. A controller is in operable communication with an input to the thermoelectric device. A sensor is in operable communication with the input to the thermoelectric device and the controller. A feedback response from the input to the thermoelectric device monitors the liquid to ice phase change of the icemaking cycle.
Abstract:
An icemaker is mounted remotely from a freezer compartment. The icemaker includes an ice mold. A thermoelectric device is provided and includes a warm side and an opposite cold side. A flow pathway is connected in communication between the cold side of the thermoelectric device and the icemaker. In one aspect, a fan is operatively positioned to move air from the fresh food compartment across the warm side of the thermoelectric device and a pump moves fluid from the cold side of the thermoelectric device to the icemaker. Cold air, such as from a refrigerator compartment, may be used to dissipate heat from the warm side of the thermoelectric device for providing cold fluid to and for cooling the ice mold of the icemaker.
Abstract:
A refrigerator is provided that includes a low energy defrost system and method for melting frost formed on an evaporator of a cooling system for the refrigerator. The low energy defrost system includes using air from the refrigerator compartment or external air adjacent the refrigerator to be directed to the evaporator and passed adjacent the evaporator coils to melt any frost formed thereon. As the air is above freezing temperature, it will melt any frost formed on the coils without the need of use an electrical heater. Re-cooled air from the melted frost may then be directed back into the refrigerator compartment to be used to aid in cooling the refrigerator compartment or keeping the refrigerator compartment at the programmed or predetermined temperature.
Abstract:
An ice maker having a housing defining an interior volume, with an ice tray rotatably coupled with the housing and horizontally suspended across the interior volume thereof. The ice tray has ice wells, defined along the bottom by a bottom surface and the sides by an interior surface of at least one containment wall, wherein the containment wall has an upper portion, including a top surface of the containment wall and the interior surface adjacent the top surface. The upper portion of the containment wall has an insulating layer applied thereto. A tray for use in the ice maker and method of manufacturing the tray are also provided.
