A modular refrigerator including a main cabinet, and a sub-cabinet selectively coupleable to a right side, an upper side, and a left side, of the main cabinet. The main cabinet includes a cooling unit, a first connection duct for cold air generated by the cooling unit to flow toward the right side, a second connection duct for the cold air to flow toward the upper side, and a third connection duct for the cold air to flow toward the left side. The sub-cabinet includes a first branch duct that, when the sub-cabinet is coupled to the right side, communicates with the first connection duct, a second branch duct that, when the sub-cabinet is coupled to the upper side, communicates with the second connection duct, and a third branch duct that, when the sub-cabinet is coupled to the left side, communicates with third connection duct.

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.

The present invention provides a refrigerator, comprising a storage compartment and a mixed air passage. Both ends of the mixed air passage have air inlets, the middle portion of the mixed air passage comprises a mixed air outlet communicating with the storage compartment, and the mixed air passage is configured to receive air flows from the two air inlets such that two air flows enter the storage compartment in a mixed manner via the mixed air outlet. The refrigerator of this invention comprises a mixed air passage, so that the air in an area of the storage compartment with a relatively high temperature can enter the mixed air passage earlier than external air or the air in the storage compartment with a relatively low temperature. Then, the two air flows are blown to the storage compartment in a mixed manner, realizing even temperature distribution in the storage compartment.

A refrigerator includes a cabinet including a refrigerating compartment and an evaporation chamber, a first door, a housing in the first door, an ice making room defining a cool air inflow hole and a cool air discharge hole, a chiller room defining a cool air discharge hole, a second door connected to the first door, a partition wall defining the ice making room, the chiller room, and a communication hole, a damper opening and closing the communication hole, a cool air supply duct connecting an outlet of the evaporation chamber and the cool air inflow hole to supply cool air of the evaporation chamber to the ice making room, and a cool air return duct having a first inlet connected to the cool air discharge hole of the ice making chamber and a second inlet connected to the cool air discharge hole of the chiller room.

A vacuum adiabatic body and a refrigerator are provided. The vacuum adiabatic body includes a support that maintains a vacuum space between a first plate and a second plate. The support includes a first support plate provided by coupling at least two partial plates to support one of the first plate or the second plate, and a second support plate that supports the other one of the first plate or the second plate.

A refrigerator includes: a storage compartment; an evaporator configured to generate cold air through heat exchange; a duct comprising a channel formed therein and through which the generated cold air flows and a cold air outlet through which the cold air is discharged to the storage compartment; a fan configured to supply the generated cold air to the storage compartment through the channel; and a cold-air control unit provided in the channel and to control a discharging amount of cold air discharged through the cold air outlet. The cold-air control unit includes a damper movable according to strength of the generated cold air supplied by the fan to adjust the cold air outlet.

A refrigeration device capable of chilling beverage ingredients and accessories is disclosed. The refrigeration device may include a first compartment that defines a first open top area, a second compartment that defines a second open top area, and a wall disposed between the first and second compartments. The refrigeration device may further include a controller configured to control the temperature in at least one of the first and second compartments, a temperature regulator configured to adjust a thermal communication between the first and second compartments, and a lid assembly movable between an opened and a closed position.

Methods of operating a refrigerator appliance are provided. The refrigerator appliance includes a cabinet defining a food storage chamber with a drawer slidably mounted within the food storage chamber. The refrigerator appliance also includes a sensor operable to detect an atmospheric condition within the food storage chamber of the drawer and a camera assembly positioned and configured for monitoring the drawer. The methods generally include obtaining an image using the camera assembly and analyzing the image to identify a first food item and a second food item in the food storage chamber of the drawer.

A refrigerator includes a crisper drawer, a frame, and a cover plate. The frame is configured to receive the crisper drawer. The frame defines at least one orifice that is configured to vent air from the crisper drawer to an exterior of the crisper drawer to control a humidity within the crisper drawer. The cover plate is secured to the frame and is at least partially disposed over the at least one orifice. The cover plate is configured to pivot relative to the frame between a first position and a second position. The cover plate restricts air flow out of the crisper drawer in the first position. The cover plate facilitates air flow out of the crisper drawer in the second position.
