A refrigerator having a cool air circulation unit for directly supplying heat-exchanged cool air to a storage compartment is disclosed. The cool air circulation unit supplies and discharges the cool air, which has been heat-exchanged in an evaporator, to and from the storage compartment through a flow passage provided inside a partition.

A refrigerator appliance includes a cabinet that defines first and second compartments. A fan assembly is configured to direct cooled air from a cooling assembly into the first and second compartments. The fan assembly includes a housing that defines an inlet, a first outlet, and a second outlet. The first outlet is in communication with the first compartment, and the second outlet is in communication with the second compartment. A fan is positioned within the housing and is configured to direct the cooled air from the inlet toward the first and second outlets. A damper assembly is configured to selectively obstruct one of the first outlet and the second outlet.

A cabinet of an appliance includes an outer wrapper defining opposing first and second sidewalls, a rear wall coupling the first and second sidewalls and an access opening and an inner liner defining an interior. The outer wrapper and the inner liner may define a sealed insulating cavity therebetween that is under vacuum. A plurality of reinforcement brackets may be disposed on the outer wrapper. The plurality of reinforcement brackets are configured to prevent deformation of the cabinet during application of the vacuum to the insulating cavity.

A refrigerated cabinet may include: a plurality of side walls forming a cabinet body and an interior storage space, the interior storage space accessible through an opening; a first door and a second door independently positionable over the opening; and a mullion formed by the second door, wherein the first door is configured to engage with the mullion. The mullion is a fixed structure formed by a portion of the second door. The refrigerated cabinet may further include a latching mechanism configured to selectively couple the first door and the second door, wherein the latching mechanism extends through the first door to engage the second door. The latching mechanism comprises a user-actuatable interface configured to decouple the first door and the second when the user-actuatable interface is engaged by a user.

A refrigerator includes a cabinet having an inner casing, an outer casing, and a thermal insulation space located between the inner casing and the outer casing and filled with a thermal insulation material, to form a pair of thermal insulation walls disposed opposite to each other. The thermal insulation walls have recesses formed in the inner casing and opened forward. A beam bridges the pair of thermal insulation walls, the beam including insert portions disposed on two ends and respectively inserted into the corresponding recesses. A first fixing mechanism is at least partially located in the recess and fixes the insert portion to the thermal insulation wall, which not only facilitates the assembly of the beam and improves production efficiency, but also is beneficial to improving a weight capacity of the beam.

A refrigerator damper system employs a fluidic valve providing switching of air between refrigerated compartments without the need for a movable valve plate such as can be obstructed by ice. In one embodiment, a bidirectional fan provides switching from a first compartment to a second compartment and then from a second compartment to a first compartment with change of fan direction.

An auger feeder includes a hopper having an inner hopper wall and an outer hopper wall where the inner hopper wall includes an air permeable surface. A space is positioned between the inner and outer hopper walls. A heater is coupled to an outside edge of the inner hopper wall or a n outside edge of the outer hopper wall while a feed screw is positioned along an inside edge of the inner hopper wall. The auger feeder additionally includes an evacuator coupled to a vacuum port that is positioned in the outer hopper wall. The auger feeder also includes an aperture exit positioned at a bottom of the inner and outer hopper walls.

An insulation system for an appliance includes a first vacuum insulated structure having a first set of sidewalls that define a first refrigerating compartment, a second vacuum insulated structure having a second set of sidewalls that define a second refrigerating compartment and a medial insulation structure having a rigid perimeter wall. The rigid perimeter wall includes a front portion that defines at least one hinge support adapted to support an appliance door. The rigid perimeter wall defines an insulating cavity that is filled with an insulating material. The first vacuum insulated structure engages a first edge of the perimeter wall and the second vacuum insulated structure engages a second edge of the perimeter wall.

A refrigerator includes a cabinet in which a storage space is formed; a main evaporator which is installed at one side of an inner portion of the storage space to cool the storage space; a case which is installed on the other side the inner portion of the storage space and defines a deep-freezing storage chamber; a drawer which is accommodated in the case so as to be retractable and withdrawable and in which food is stored; and a rapid cooling module which is provided on a rear side of the inner portion of the case and rapidly cools the deep-freezing storage chamber, in which the rapid cooling module may includes an auxiliary evaporator; and a thermoelectric device which is coupled to the auxiliary evaporator and cools the deep-freezing storage chamber through heat exchange by heat conduction.

A refrigerator includes a storage compartment and a mullion assembly pivotally coupled to one of a first door and a second door. The mullion assembly includes a cavity with an insulating member disposed therein. One or more sensor assemblies are coupled to the mullion assembly and configured to collect data sufficient to calculate a dew point temperature of the mullion assembly and an actual temperature of the mullion assembly. A heating element is coupled to the mullion assembly and is selectively activated by a controller based on information provided from the one or more sensor assemblies. The heating element is powered using a modulated power level that is inversely proportionate to the difference in temperature between the mullion assembly and the calculated dew point.
