Provided in the application is a refrigerator. The refrigerator may comprise: a cabinet having a cooling chamber and at least one storage chamber, and an air duct assembly installed on the cabinet. The air duct assembly has a plurality of air duct layers sequentially arranged in a longitudinal direction of the cabinet and each of the air duct layers has one or more air ducts.

An air supply assembly for a refrigerator, includes: an air duct cover plate defining, together with a refrigerator liner, an air supply space and configured to isolate the air supply space from a storage space in a compartment of the refrigerator, and a centrifugal wind wheel arranged in the air supply space, and axially sucking air in and blowing the air out towards a peripheral side, wherein a plurality of air return ports are provided in the air duct cover plate to allow air in the storage space to enter the air supply space; and the centrifugal wind wheel abuts against an inner side of the air duct cover plate and is configured to suck air in from a rear side thereof, such that air entering the air supply space via the air return ports is sucked in from the rear side of the centrifugal wind wheel.

A method for controlling a refrigerator includes determining whether an ice bin accommodated in an ice making compartment that receives cold air from the first storage compartment is full of stored ice, determining, by a controller, whether an algorithm that prevents the ice stored in the ice bin from melting needs to be performed upon determining that the ice bin is full, and performing the algorithm.

A refrigerator includes an apparatus for producing dairy products. The refrigerator includes an outer cabinet, an inner cabinet provided inside the outer cabinet and including a refrigerator compartment to formed therein, and an dairy product maker provided inside the refrigerator compartment. The dairy product maker includes a case including a suction port and a discharge port to allow cool air to flow in and out, respectively, a container to store the produced dairy product therein, a heater to apply heat to the container to produce the dairy product in the container, ribs protruding from an inner surface of the case to form a cooling flow channel with the inner surface and provided between the suction port and the discharge port to cool the container, and a guide slit to guide the produced dairy product overflowing into the cooling flow channel, to a bottom surface of the case.

In one instance, a cooling unit for cooling a refrigerated room includes a fan base and a fan guard that both twist and rotate to change pitch thereby allowing the cooling unit air to be directed in many directions as desired. The fan base has a flange portion and a conduit portion. The conduit portion of the fan base mates with an opening in a conduit member of the fan guard. The opening in the fan guard is sized and configured to form an interference fit with at least a portion of a conduit portion of the fan base while allowing rotation of the fan guard relative to the fan base about the longitudinal axis. The second longitudinal end of the fan-guard conduit member is at least partially angled to allow the rotation about a lateral axis in order to pitch the direction of the grill front wall.

A branched air supply device includes: a shell having a peripheral wall portion, with the peripheral wall portion being provided with a plurality of air supply ports; a plurality of baffles, with each of the baffles being rotatably mounted at one of the air supply ports; a plurality of transmission assemblies, with each of the transmission assemblies being provided with a rotating member and a first transmission mechanism, and each of the first transmission mechanisms being configured to transmit a rotational motion of a corresponding rotating member to one of the baffles, so that the baffle is at rest or rotates; and a driving device having a driving source and a second transmission mechanism, with the second transmission mechanism being configured to transmit one motion, output by the driving source, to the plurality of rotating members, so that each of the rotating members is at rest or rotates.

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.

A deodorizing apparatus including: a base, in which a suction port and a discharge port are disposed; a cover coupled to the base; a suction fan fixed to the base so as to suction air through the suction port; a first fixing member disposed between the suction port and the discharge port so as to support a filter; a light emitting module including a light emitting diode; and a second fixing member for supporting the light emitting module. The first fixing member includes a first body part for spacing the filter apart from the base.

In a refrigeration unit for use in cooling a space, such as a walk-in cold space, or other system, an easy access fan motor assembly is provided. A motor mount holds the motor with a plurality of legs that couple to a front panel using stud inserts. In some instances the legs are curved and looked like spider legs. A fan guard member covers the fan and is also attached to the stud inserts. By removing fasteners on the stud inserts, the guard member may be removed and the fan motor assembly may be removed from a position exterior to the refrigeration unit for repair or serving. Other systems and methods are disclosed.

The present disclosure relates to a refrigerator and a control method thereof in one embodiment. The refrigerator in one embodiment may include a storage part including a compressor and an evaporator and configured to store a food item at a low temperature using air cooled by the evaporator, an ice making compartment configured to make or store ice using air cooled by the evaporator, and a fan for making ice allowing air cooled by the evaporator to flow to the ice making compartment, wherein a rotation speed of the fan for making ice changes while the fan for making ice continues to operate during operation of the compressor.
