A refrigerator includes a lowermost storage liner, an evaporator, an air supply duct, and at least one air supply fan. A storage compartment and a cooling chamber positioned under the storage compartment are defined in the storage liner. The evaporator is disposed in the cooling chamber and is configured to cool air passing through the evaporator so as to form cooling air supplied to the storage compartment. The air supply duct is disposed in a space defined by the storage liner and is configured to convey the cooling air cooled by the evaporator to the storage compartment. The air supply fan is disposed in the air supply duct and is configured to promote air circulation between the cooling chamber and the storage compartment. According to the refrigerator of the present invention, by disposing the air supply fan in the air supply duct, the cooling chamber is prevented from being occupied by the air supply fan, the height of the cooling chamber can be reduced, the storage volume of the storage compartment above the cooling chamber can be increased, the distance between the air supply fan and the evaporator can be relatively increased, and the

A refrigerator including a cabinet including an insulator provided between an inner case and an outer case, a cold air duct embedded in the insulator to circulate cold air through the storage compartment, a cooling module mounting unit provided at a lower portion of the cabinet, and a cooling module including a module body in which an evaporator, a condenser, a compressor, and a cooling fan are installed and having an accommodating portion to accommodate the evaporator in a lying state, the cooling module being provided with a connection opening communicating with the cold air duct when mounted on the cooling module mounting unit.

A refrigerator includes a duct module, wherein the duct modules include a front panel and a rear panel coupled to each other in the front-rear direction and forming a flow path, a plurality of flow path forming protrusions extending from a front surface of the front panel to form a flow path therebetween, and a sealing surface extending parallel to the rear surface of the front panel from front ends of the plurality of flow path forming protrusions and in surface contact with the rear surface of the front panel.

A refrigerator includes an inner case including (i) a refrigerating case that defines a refrigerator compartment and (ii) a freezing case that defines a freezer compartment, an outer case disposed outside the inner case, a connection duct disposed between the inner case and the outer case, and a refrigerator compartment cold air supply duct that is detachably coupled to a rear inner surface of the refrigerating case and in fluid communication with the connection duct. The connection duct and the refrigerator compartment cold air supply duct are in communication on a rear surface of the refrigerating case with the refrigerating case interposed therebetween, thereby reducing the area occupied by the refrigerator compartment cold air supply duct disposed in the rear inner surface of the refrigerator compartment.

The present disclosure relates to a refrigerator that comprises a refrigerator case, a freezer case, a door, an ice maker, an evaporator, and an ice maker duct to supply the cold air that is generated by the evaporator to the ice maker and to return the cold air to the freezer compartment, wherein the ice maker duct comprises an inner ice maker duct and an outer ice maker duct that are divided by a vertical surface formed in a direction in which cold air flows, the inner ice maker duct has an inner convex concave part that is formed convexly and concavely, at an edge thereof, and the outer ice maker duct has an outer convex concave part that is formed convexly and concavely and engages with the inner convex concave part, at an edge thereof.

A refrigerator may include an air duct cover plate, a closed air cavity, an evaporator, and an air guiding rib. The air duct cover plate and a liner of the refrigerator enclose the closed air cavity. The evaporator is disposed on an outer surface of the liner. The air guiding rib is disposed in the closed air cavity. The air guiding rib divides the closed air cavity into an air intake region, a first supply region, and a second supply region that are sequentially in fluid communication. The first supply region is located above the air intake region and includes an upper air outlet. The second supply region is located below the first supply region and is separated from the air intake region by the air guiding rib. A lower air outlet is disposed in the second supply region.

A refrigerator according to one embodiment of the present invention comprises: a main body; a first storage chamber and a second storage chamber provided in the main body so that the front surfaces thereof are opened; an evaporator which is disposed inside the main body and which generates cold air; a first duct for supplying the cold air to the first storage chamber; a second duct for supplying the cold air to the second storage chamber; and a connecting duct for connecting the first duct and the second duct so as to allow the cold air generated by the evaporator to flow to the second duct, wherein the second duct includes a connecting port connected to the connecting duct, a discharge port through which the cold air is discharged, a discharge path for connecting the connecting port and the discharge port, and a connecting path for connecting the inside of the second storage chamber and the discharge path, the discharge path includes a minimum region in which the cross sectional area thereof in a vertical direction or a longitudinal direction is minimized, and the connecting path is provided to connect the inside of the second storage chamber and the minimum region.

A refrigerator includes a first discharge part such that a temperature distribution difference between the upper section (upper space relative to the center portion of the inside of a storage compartment) of the inside of the storage compartment and the lower section (lower space relative to the center portion of the inside of the storage compartment) of the inside of the storage compartment may be reduced. In addition, water produced in the surrounding area of a blower fan may flow down into a flow path formed under the blower fan such that the loss of the flow amount of cold air may be reduced. Due to such a structure of the refrigerator, even temperature distribution inside of the storage compartment may be realized, and consumption efficiency may be improved.

A household refrigeration appliance has a thermally-insulated body with an interior container that delimits a coolable interior space, a refrigeration circuit for cooling the coolable interior space and at least one fan. During the proper operation of the household refrigeration appliance, the fan is operated in a closed loop speed-controlled manner according to an at least indirectly specified desired rotational speed of the fan. During an inspection mode, the fan is operated without closed loop speed control, the actual rotational speed of the fan is ascertained and the actual rotational speed is evaluated in order to detect an abnormal operating state of the fan.

Provided is a refrigeration appliance that includes a fresh food compartment and a freezer compartment. An opening is provided between the freezer compartment and the fresh food compartment to allow air to flow from the fresh food compartment to the freezer compartment and an air tower located within the fresh food compartment is adapted to deliver air from the freezer compartment to the fresh food compartment.
