A refrigerator is proposed. The refrigerator includes a manipulation part including a rotating shaft and a manipulation knob, an opening/closing part configured to have a curved surface and located at a position adjacent to the circumference of the rotating shaft such that the opening/closing part opens and closes a communication portion between an inlet part and an enlarged part of a flow guide, and an angle limiting part configured to limit the rotation angle of the manipulation knob, whereby the manipulation knob of a thermostat for temperature control of the freezer compartment is configured to have the operation angle of 120˜160°, thereby improving manipulation satisfaction during the manipulation of the manipulation knob by a user.

Refrigerator

A refrigerator includes a cabinet, a first storage chamber and a second storage chamber, and a grille fan assembly partitioning the first storage chamber into a space receiving an evaporator, and a grille fan assembly including a grille panel, a shroud supporting a first fan and a second fan, a heat insulating member provided between the grille panel and the shroud and defining a first flow path configured to supply cold air blown by the first fan to the first storage chamber and a second flow path configured to supply cold air blown by the second fan to the second storage chamber, and a duct connector provided at a position corresponding to the second fan between the shroud and the heat insulating member and connected to the second flow path part to define an independent flow path.

A refrigerator and a method of controlling an operation thereof are proposed. In the refrigerator and method thereof, heat control of heaters for preventing a damper from freezing is performed according to at least any one condition set in consideration of a room temperature and refrigerator internal humidity. Accordingly, consumption of power due to unnecessary heat generation of the heaters may be reduced, thereby improving the power consumption.

Refrigerator and operating method thereof

A refrigerator includes a cabinet, an evaporator, a freezer compartment grille assembly, a refrigerating compartment grille assembly, a refrigerating compartment door, and a cold air duct for door cooling. Particularly, the cold air duct for door cooling is located to be as apart as possible from a hot line or an outer casing so as to reduce heat loss and power consumption due to the heat loss.

A refrigerator includes: an evaporator provided in a storage space and configured to supply cold air to the storage space, a duct assembly provided above the evaporator and configured to guide the cold air supplied to the storage space, a door supply duct coupled to the duct assembly and configured to guide a part of the cold air flowing through the duct assembly to a door, and a fan motor assembly coupled to a lower end of the duct assembly and configured to suction air cooled by the evaporator and blow the suctioned air into the duct assembly. The duct assembly defines a first passage and a second passage that are spaced apart from each other, where the second passage includes a main passage configured to supply the cold air to the storage space and a sub-passage branched from the main passage and coupled to the door supply duct.

A refrigerator includes a cool air flow path for an ice making compartment and a cool air flow path for a freezing compartment. The cool air flow paths are integrally formed on opposed surfaces between a shroud and a grill fan. A freezing fan and an ice making fan are collectively installed at the shroud. The cool air flow path for the ice making compartment and the cool air flow path for the freezing compartment are defined between the grill fan and the shroud by the operation of intimately coupling the shroud to the grill fan.

A control method for controlling a refrigerator includes a first step for driving a compressor for compressing a refrigerant and a fan for moving air, a second step for driving the compressor and stopping the fan, a third step for stopping the compressor and driving the fan, and a fourth step for stopping the compressor and the fan.

Refrigerator and control method therefor

Provided is a refrigerator. The refrigerator includes a cabinet including an inner case defining a storage compartment, an outer case surrounding the outside of the inner case, and an insulation material provided between the inner case and the outer case, a storage compartment door opening and closing the storage compartment, a cold air duct provided in the storage compartment and disposed in an upper side of the storage compartment to discharge cold air to the storage compartment, and a guide duct disposed outside the inner case to communicate with the cold air duct and extending to the storage compartment door to guide the cold air received from the cold air duct to the storage compartment door.

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.

Control method for refrigerator

A control method for a refrigerator comprises: sensing a temperature of a first storage chamber; increasing an output of a first cooling fan if the temperature reaches a value greater than or equal to a second reference temperature; reducing the output of the first cooling fan if the temperature reaches a value less than or equal to a first reference temperature; increasing the output of the first cooling fan if a first reference time has passed after the temperature has reached the value or if the temperature reaches a first setting temperature between the first reference temperature and the second reference temperature; and reducing the output of the first cooling fan if a second reference time has passed after the output of the first cooling fan has been changed, or if the temperature reaches a preset second setting temperature between the first setting temperature and the first reference temperature.

Disclosed is a refrigerator including a main body forming a refrigerating chamber and a freezing chamber each including a temperature sensor, a cooling unit having a compressor and an evaporator accommodated inside the main body and driven to circulate a refrigerant in the compressor and the evaporator to generate cold air around the evaporator, a fan positioned inside the main body to supply the cold air to the freezing chamber, a damper positioned between the freezing chamber and the refrigerating chamber and opened and closed to allow the freezing chamber and the refrigerating chamber to selectively communicate with each other, and a controller controlling the damper for a predetermined damper opening time when a temperature of the freezing chamber reaches a freezing satisfaction temperature according to driving of the cooling unit. A temperature change of the refrigerating chamber over time may be reduced and power consumption may be improved.

A control method for a refrigerator comprises: decreasing an output of at least one of a cold air supply means for a first storage chamber or stopping the cold air supply means, if a sensed temperature of the first storage chamber reaches a value less than or equal to a second reference temperature; increasing the output, if a certain time has passed after the temperature has reached the value less than or equal to the second reference temperature, or if the temperature reaches a first specific value between a first reference temperature and the second reference temperature; and decreasing the output or stopping the cold air supply means, if a certain time has passed after the output of the air supply means has been changed in a previous step, or if the temperature reaches a preset second specific value between the first specific value and the second reference temperature.

A refrigerator comprises: a cabinet having a refrigerating chamber; a refrigerating chamber evaporator provided to correspond to the refrigerating chamber, and configured to generate cool air by a driving of a compressor; an evaporator temperature sensor mounted to the refrigerating chamber evaporator, and configured to sense a temperature; a blower fan configured to supply cool air generated from the refrigerating chamber evaporator to the refrigerating chamber; and a controller configured to determine whether to stop the blower fan or not, based on a temperature of the refrigerating chamber evaporator sensed by the evaporator temperature sensor when the compressor is stopped.
