Abstract:
An apparatus, method and system configured to produce and provide on-demand, immediate sequential dispensing of varying levels of carbonated water, such as carbonated water having a level of carbonation selected by an end-user, is disclosed. In one aspect, immediate sequential dispensing of varying levels of carbonated water is provided by varying the rate of agitation during a fixed agitation interval. The carbonating unit has a volume with an inlet in communication with a source of carbonating gas and noncarbonated water. An agitator is housed within the volume of the carbonating unit and is operated by a variable speed actuator.
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 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 making tray has a water basin with a thermally conductive floor and a flexible grid positioned therein to define a plurality of ice making compartments. A motor is coupled to the basin to rotate the basin and grid to an inverted position, and a link is coupled between the motor and drive such that the grid is rotatable out of the basin and is flexed to release ice cubes formed therein.
Abstract:
An ice maker assembly includes an ice forming plate and a cooling source thermally engaged to a bottom surface of the ice forming plate. The cooling source is configured to freeze water coming into contact with a top surface of the ice forming plate. A containment wall surrounds the top surface of the ice forming plate to define an ice tray that is configured to retain water. An electrical drive body is rotatably coupled to the ice tray and is configured to oscillate the ice-forming plate in a rocking cycle about a transverse axis of the ice tray. A median wall divides the ice tray along the transverse axis into a first reservoir and a second reservoir. The rocking cycle causes water to repeatedly move over the median wall to form layers of an ice piece within each reservoir of the ice tray.
Abstract:
An ice making tray has an array of individual ice cube compartments. A mechanical oscillating mechanism is coupled to the tray and rotates the tray from a horizontal plane in opposite directions along an axis through an angle φ of about 20° to 40°, such that water in the tray moves between ice cube compartments. The frequency of oscillation (ω) is harmonically related to the frequency of movement of water in the tray and is about equal to or about twice the frequency of movement of water in the tray. In a preferred embodiment, the floor of the tray is a thermally conductive material in contact with a thermoelectric plate used to freeze the water as well as being subsequently heated to release the formed ice cubes.
Abstract:
An ice maker has a mold with a first piece and a second piece. A cavity within the mold includes a first reservoir in the first piece and a second reservoir in the second piece that align to substantially enclose the cavity. A fluid intake aperture in the first piece extends to the cavity for injecting water therein. A thermoelectric device has a cold side thermally coupled to the exterior surface of the second piece. The thermoelectric device transfers heat from the cold side to a hot side to provide a first temperature to the mold. A removable cooling source is thermally coupled to the hot side of the thermoelectric device. The cooling source is configured to reduce the temperature of the hot side to allow the cold side to provide a second temperature that is cooler than the first temperature to freeze the water in the cavity.
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. A thermoelectric device is provided and includes a warm side and an opposite cold side. A fluid pathway is connected in communication between the cold side of the thermoelectric device and the icemaker. A pump moves fluid from the cold side of the thermoelectric device to the icemaker. Cold fluid or air may be taken from the freezer compartment to dissipate heat from the warm side of the thermoelectric device for providing cold fluid to and for cooling the ice mold or cool/warm fluid to other cooling or warming applications in the refrigerator compartment or on the refrigerator compartment door.
