Abstract: A refrigerator includes a cabinet, a door, an ice maker provided in the cabinet or the door, a water supply flow path configured to connect the ice maker to a water supply source outside the cabinet, a filter connected to the water supply flow path to purify water supplied to the ice maker, at least one valve provided in the water supply flow path, and a controller configured to control operation of the ice maker and the valve. The water supply flow path includes an ice maker pipe connected to the ice maker to supply water for ice making and a drain pipe configured to drain water in the water supply flow path to outside of the cabinet. The controller controls the valve to block water supply to the ice maker and drain water through the drain pipe when a drain signal is input.

Abstract: A control method for a refrigerator comprises: driving a first cooling fan to cool a first storage chamber; adjusting a damper to cause cold air to simultaneously flow through first and second cold-air passages; adjusting a damper to reduce the opening angle of the first cold-air passage, when the temperature of a high-temperature chamber reaches a value smaller than or equal to a second reference temperature for the high-temperature chamber; adjusting a damper to reduce the opening angle of the second cold-air passage, when the temperature of a low-temperature chamber reaches a value smaller than or equal to a second reference temperature for the low-temperature chamber; and driving a second cooling fan to cool a second storage chamber. When a predetermined time elapses or the sensed temperature of the high-temperature chamber reaches a first set temperature, the damper is adjusted to increase the opening angle of the first cold-air passage.

Abstract: A refrigerator is proposed. The refrigerator includes a refrigerating compartment, a freezing compartment, and an ice-making compartment. The refrigerating compartment is configured to receive cool air from a refrigerating compartment side grill fan assembly, and the ice-making compartment is configured to be located in any one refrigerating compartment door and to receive cool air from a freezing compartment side grill fan assembly with the freezing compartment. The refrigerating compartment side grill fan assembly is configured to supply a greater amount of cool air to a space at a refrigerating compartment door without the ice-making compartment than the amount of cool air supplied to other spaces, and the freezing compartment side grill fan assembly is configured to supply a greater amount of cool air to a space communicating with a recovery duct for the ice-making compartment than the amount of cool air supplied to other spaces.
