DIRECT COOLING ICE MAKER
A refrigeration appliance includes a fresh food compartment for storing food items in a refrigerated environment having a target temperature above 0° C., a freezer compartment for storing food items in a sub-freezing environment having a target temperature below 0° C., a system evaporator for providing a cooling effect to at least one of the fresh food compartment and the freezer compartment, and an ice tray assembly disposed within the fresh food compartment for freezing water into ice pieces. The ice tray assembly includes an ice mold with an upper surface comprising a plurality of cavities formed therein for the ice pieces, a heater disposed on the ice mold and an ice maker refrigerant tube abutting at least one lateral side surface of the ice mold and cooling the ice mold to a temperature below 0° C. via thermal conduction and a cover having a water fill cup integrated into the cover and an outlet aligned with an inlet of the ice mold.
Refrigerator and method for controlling the same
The method for controlling the refrigerator includes operating a first cooling cycle for cooling the first storage compartment to operate the compressor and operating a first fan for the first storage compartment, and switching the first cooling cycle to a second cooling cycle for cooling the second storage compartment to operate the compressor and operating a second fan when a stop condition of the first cooling cycle is satisfied. A temperature of each storage compartment is sensed at sampling time intervals in each cooling cycle. Further, a cooling power of the compressor is determined for each sampling time based on a sensed current temperature of the storage compartment, and the compressor is operated at the determined cooling power.
STAND-ALONE ICE AND BEVERAGE APPLIANCE
A stand-alone ice and beverage dispenser is provided. Appliance includes a cabinet defining a chilled chamber, a bottom portion and a countertop. Appliance includes an ice maker assembly mounted on the countertop, a liquid dispenser assembly mounted on the countertop, and a sealed refrigeration system. Sealed refrigeration system includes a compressor, condenser, chamber evaporator, and an ice maker assembly evaporator fluidly coupled through a refrigerant conduit. The compressor is operably coupled to the refrigerant conduit for circulating a flow of refrigerant through the refrigerant conduit. Appliance also includes refrigerant valve assembly including one or more valves. Refrigerant valve assembly is configured to selectively provide refrigerant to chamber evaporator to refrigerate chilled chamber and selectively provide refrigerant to the ice maker assembly evaporator for ice production.
REFRIGERATOR AND METHOD OF CONTROLLING THE SAME
A refrigerator includes a compressor, a condenser, an evaporator, switching valve, an ice-making device, a controller, and a first refrigerant pipe and a second refrigerant pipe connected between the condenser and the evaporator. The switching valve is configured to guide the refrigerant condensed in the condenser to the first refrigerant pipe or the second refrigerant pipe. The ice-making device allows the first refrigerant pipe to pass therethrough and configured to cool water stored in an ice-making tray. The controller is configured to control the switching valve to guide the refrigerant to the ice-making device through the first refrigerant pipe. In response to a temperature of the ice-making tray falling to a level lower than or equal to a reference temperature, the controller is configured to control the switching valve to prevent the refrigerant from being guided to the first refrigerant pipe and supply water to the ice-making tray.
