A refrigerator includes a body including an inner case, a first storage compartment, a second storage compartment, a third storage compartment, a first partition between the second storage and the third storage compartments, a second partition between the first and the second storage compartments, a cold air supplier in the third storage compartment to generate cold air, a first communication hole, a second communication hole to face the first communication hole, a first guide duct formed in the first partition to guide the cold air from the first communication hole to the second communication hole, and a second guide duct formed in the second partition to guide the cold air which has flown to the first guide duct, to the second storage compartment, the second guide duct connected to the first guide duct through the second communication hole.

A refrigerator includes a main body in which a first storage compartment is defined, and a heat exchange chamber defined in the main body. An evaporator received in the heat exchange chamber. A second storage compartment is provided in the first storage compartment and a quick cooling module to cool an inside of the second storage compartment is provided, where the quick cooling module heat-exchanges with a refrigerant pipe of the evaporator. The quick cooling module includes a thermal conductive unit in thermal conduction with the refrigerant pipe, and a thermoelectric device having a first surface in thermal conduction with the thermal conductive unit to heat-exchange with the thermal conductive unit when current is supplied and a second surface facing the second storage compartment.

A domestic refrigerator has a refrigeration compartment and a container which can be accommodated in the refrigeration compartment and has a lower part for receiving products to be refrigerated and a cover that can cover the lower part. The container has an air inlet opening and an air outlet opening that is at a distance from the air inlet opening. The domestic refrigerator also has a controllable air flow adjustment device and is configured to vary a volume flow rate of an air flow, which enters the container from the refrigeration compartment through the air inlet opening, between at least two values by adjusting an adjustment parameter of the air flow adjustment device. Furthermore, a method ventilates the container which is accommodated in the refrigeration compartment and has the air inlet opening and the air outlet opening.

A refrigerator may include: a refrigerator compartment, a convertible compartment, an evaporator disposed in the convertible compartment; and a grill pan assembly forming a space where the evaporator is disposed by dividing the inside of the convertible compartment. The grill pan assembly may include an insulating member, a convertible compartment fan, a refrigerator compartment fan, and an opening device formed at the insulating member from the convertible compartment channel to the refrigerator compartment channel.

A refrigerator to be installed in a storage space defined by a wall of an object includes a contact mechanism so that the refrigerator makes contact with the wall, and thus the refrigerator can be installed.

A refrigerator appliance includes a cabinet with at least one food storage chamber defined in the cabinet. The refrigerator appliance also includes a sealed cooling system in fluid communication with the at least one food storage chamber via a multi-flow system. A plurality of independently cooled zones are defined within the at least one food storage chamber. The refrigerator appliance also includes a temperature control module selectively positionable in one of the plurality of zones. Methods of operating the refrigerator appliance may include and/or a controller of the refrigerator appliance may be configured for locating the temperature control module, receiving a temperature setting from the temperature control module, and adjusting operation of at least one of the sealed cooling system and the multi-flow system in response to the received temperature setting from the temperature control module.

An ice maker for a refrigerating appliance includes an ice tray having ice-forming compartments. Each ice-forming compartment includes sidewalls and a base defining an internal freezing chamber. The ice maker also includes an air flow diverter having an outer frame and a plurality of internal diverting fins that define tuned duct flutes for receiving a stream of intake air from an air handling system and distributing the stream of intake air through the plurality of tuned duct flutes as streams of cooling air directed toward the ice-forming compartments. The internal diverting fins include a predetermined spacing pattern that individually tunes each of the tuned duct flutes. The predetermined spacing pattern evenly distributes the stream of intake air among the plurality of tuned duct flutes such that each of the plurality of streams of cooling air include substantially equal air flow rates.

A system for blast-freezing items includes a plurality of cells arranged side-by-side, each cell including a housing with a bay space, a plenum, a front air passage, a rear air passage, and a fan. The fan is positioned in the plenum and configured to circulate air through the bay space. Each cell also includes a plurality of channels to separate pathways of air to segments of the bay space. The system also includes a plurality of crane rails extending between rows of cells and at least one crane capable of traveling along the plurality of crane rails to load or unload each of the plurality of cells.

An ice making device for a refrigerator including a cold air generation system and a circulation unit. An ice maker is disposed within an ice-making room and configured to produce ice. The cold air generation system can supply cold air to the ice-making room in the ice making device. A circulation unit is disposed within the ice-making room to drive cold air into the ice-making room. The circulation unit may include a fan motor and an air guide.

A multi-duct that is coupled to a surface of a cabinet including a plurality of spaces divided by one or more shelves in a refrigerator and that includes: a flow channel (i) that extends between a first end of the flow channel and a second end of the flow channel in a first direction, (ii) that passes through the plurality of spaces, and (iii) that guides cool air from the first end to the second end; an inlet; and a plurality of outlets, wherein the flow channel includes a first curved flow channel (i) that is configured to discharge cool air through a first outlet of the plurality of outlets and (ii) that has a concave shape that is curved toward a second direction opposite to a direction in which cool air is discharged through the first outlet is disclosed.
