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 multilayer cover has a sandwich design for placement on a drawer of a vacuum drawer device, and the cover allows an evacuation of the drawer interior after sealing against the drawer. The cover has an outer air-tight cover layer and a core layer, recesses molded into the core layer and partly into one of the at least one outer cover layer, and an evacuation channel, a pump, and at least one sensor are arranged therein. The cover is to have a more compact design with a very low height, resulting in a minimal susceptibility to malfunction. This is achieved in that a printed circuit board is arranged on one of the at least one outer air-tight cover layers so as to face the core layer or the at least one outer air-tight cover layer is designed as a printed circuit board on which the core layer lies and on which the electric components integrated into the cover are mechanically held and are electrically connected.

A product merchandising system includes a housing having a top surface, two side surfaces spaced apart from one another defining a width-direction of the housing, and a front surface and rear surface spaced apart from one another defining a depth-direction of the housing. The system includes a product support system configured to support rows of products along a width of the housing, each row disposed at a position along the depth of the housing, the first row being towards the front surface of the housing. A cooling system includes a cooling system including a cooling heat exchanger generating an airflow, a deflector configured to direct the airflow through the cooling heat exchanger and towards a bottom of the housing, and a nozzle below the deflector and configured to direct the airflow towards a bottom of the housing through an outlet aperture and between a first two rows of products.

Systems and methods are disclosed herein that include providing a cooler with a supply duct, a plurality of shelf plenums connected in fluid communication with the supply duct, and a return duct to implement precise temperature control over an internal cooling space of the cooler. Each of the shelf plenums may include openings disposed in a top surface of each shelf plenum. A supply airflow generated by a fan of a refrigeration system may pass the supply airflow through the supply duct to each of the plurality of shelf plenums, where the supply airflow may exit the shelf plenums through the openings in each shelf plenum to directly contact beverages and/or food products disposed on the top surface of the shelf plenums. The cooler may be further operated to supercool liquid beverages below a freezing point of the beverages without causing solidification and/or crystallization of the beverages.

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.

A refrigerator a duct arranged to partition an inner space of a storage chamber body into a storage chamber and an air flow channel, wherein the duct has an ejection hole defined therein; a roll-bond evaporator disposed in the air flow channel, wherein the roll-bond evaporator has a top and a bottom, a left end and a right end; a blowing fan configured to draw air from the storage chamber to blow the air into the air flow channel; and a defrost sensor closer to one of the top and bottom than the other of the top and the bottom, wherein said one is closer to the blowing fan than the other, wherein the sensor is closer to one of the left end and the right end than the other of the left end and the right end.

The present invention relates to an apparatus capable of purifying air and maintaining freshness inside a refrigerator while minimizing deformation of the structure of an existing refrigerator, and a method for controlling the same. The apparatus for air purification and freshness maintenance according to the present invention is formed separately from a storage space (12) of a refrigerator (10) and is installed on a cooling passage (14) which communicates with the storage space (12) through an inlet (13) and an outlet (15), wherein a photocatalyst filter (30) is installed in the vicinity of the outlet (15) within the cooling passage (14), and a plurality of cells (32) forming an air vent are formed in the photocatalyst filter (30) in the same direction as the air flow direction within the cooling passage (14), in which a UV LED (41) for radiating ultraviolet rays toward the cells (32) of the photocatalyst filter (30) is installed.

The present invention relates to a cover for cooling fins disposed in an interior space of a refrigerator. The cover comprises an inlet portion comprising at least one inlet, wherein said inlet portion is adapted such that an air flow is allowed to enter through said inlet. The cover further comprises an outlet portion comprising at least a first outlet, wherein said first outlet is arranged relative to said inlet such that said air flow is able to exit through said first outlet. The first outlet is configured such that said air flow exiting through said first outlet is directed to at least a first volume in said interior space of said refrigerator. The invention is further directed to a refrigerator for a vehicle having an inventive cover.
