Abstract:
An ice piece release and formation system (and associated methods) including a chilled compartment, a warm section, a tray in thermal communication with the chilled compartment, and a reservoir assembly in thermal communication with the warm section. The tray includes ice piece-forming receptacles and a cavity in thermal communication with the receptacles. The reservoir assembly includes chambers in fluid communication with the cavity and a driving body for moving the chambers. The system further includes a heat-exchanging fluid that resides in the chambers and the cavity of the tray. The driving body and the reservoir assembly are further adapted to move each of the chambers to a position above the cavity, and the other of the chambers to a position below the cavity, such that the fluid within the chamber positioned above the cavity flows into the cavity.
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.
Abstract:
An ice making assembly includes an ice maker including a mold body defining a one or more compartments for forming ice cubes therein, a harvesting assembly removes an ice cube from the compartment, and one or more bimetallic elements. Each bimetallic element is configured with a respective one of the compartments so that when energized the bimetallic element deforms with a portion moving in a direction so as to assist in removing an ice cube from the compartment. Related refrigeration appliances are also disclosed.
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:
This invention relates to a portable onsite ice making apparatus having a bypass tube, which includes a compressor equipped with a condenser having heat removal capacity of about 2,400˜2,600 BTU/hr; an expansion valve; an evaporator being in heat exchange relationship with an ice making tray; a bypass tube for the refrigerant to bypass the condenser and the expansion valve; and a switching means selectively changing the flow of the refrigerant from the compressor to the condenser or from the compressor to the bypass tube. The portable ice making apparatus has heat removal capacity to cool the ice making tray to −27° C.˜−26° C. within 3 minutes and heating capacity to heat the ice making tray from about −27° C.˜−26° C. to about 50° C.˜−60° C. within 30 seconds. The area of the capillary tube in the bypass tube to the area of the first discharging tube is about 1/25˜ 1/10.
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 ice maker of a domestic refrigerator that includes an ice mold having an electrically-conductive polymeric body and a plurality of cavities defined in the polymeric body. Each cavity is sized to receive a quantity of fluid corresponding to a single ice cube. A pair of electrodes is engaged with a bottom surface of the polymeric body. The polymeric body has a first electrical conductivity at a first operating temperature and a second electrical conductivity that is less than the first electrical conductivity at a second operating temperature. The second operating temperature is greater than the first operating temperature.
Abstract:
A cooling system (10) for cooling an aircraft device (12) comprises an evaporator (14, 16, 18) for receiving a fluid (F) which is to be evaporated, a first adsorber (24) which contains a medium (28) for the adsorption of the fluid (F) which is evaporated in the evaporator (14, 16, 18), as well as a second adsorber (26) which contains a medium for the adsorption of the fluid (F) which is evaporated in the evaporator (14, 16, 18). A control system (22) is adapted to establish or to interrupt a fluid connection between the evaporator (14, 16, 18) and the first and/or the second adsorber(s) (24, 26).
Abstract:
Provided is an ice maker, which includes an upper tray, a lower tray, and a rotation shaft. Upper cells of hemispherical shapes are arrayed in the upper tray. Lower cells of hemispherical shapes are arrayed in the lower tray that is rotatably connected to the upper tray. The rotation shaft is connected to a rear end of the lower tray and a rear end of the upper tray to rotate the lower tray relative to the upper tray. A rotation guide part rounded with a predetermined curvature is disposed in a region where the lower tray contacts the upper tray while the lower tray is rotated.
