Provided are a device (100) for self-adaptive regulation of air volume and a refrigerator (200) having the same. The regulating device (100) comprises: a drainage and air guide cavity (1), arranged on the back of a freezing chamber (201) of a refrigerator, the drainage and air guide cavity (1) comprising a funnel-shaped air collecting cavity (11) and a conical air outlet cavity (12) connected to the funnel-shaped air collecting cavity (11), an outlet of the conical air outlet cavity (12) facing a refrigerating chamber; a drainage tongue (2), provided in the conical air outlet cavity (12) so as to create a first outlet duct (122) and a second outlet duct (123) within the conical air outlet cavity (12), an inlet (20a) of the first outlet duct (122) being located on an extension line of a left side wall (113) of the funnel-shaped air collecting cavity (11) and an inlet (21a) of the second outlet duct (123) being located on an extension line of a right side wall (112) of the funnel-shaped air collecting cavity (11); and a fan (3) arranged inside of the funnel-shaped air collecting cavity (11). By rotating the fan (3), cold air is conveyed through the first outlet duct (122) and the second outlet duct (123) and into a refrigerating chamber (202) under the guide of the left side wall (113) or right side wall (112) of the funnel-shaped air collecting cavity (11).

A rotation transmission mechanism may include a plurality of rotation transmission members having a drive wheel and a driven wheel, and an urging member which urges the driven wheel in a reverse direction to a rotational direction by power of the drive source. The drive wheel and the driven wheel are provided with engagement parts structured to transmit turning of the drive wheel to the driven wheel, the drive wheel is provided with a cam face forming part on which the engagement part of the driven wheel is slid at a rotational position where the engagement parts are not engaged with each other, and a brake member structured to generate a rotation load is disposed in a range on an upstream side of a power transmission path including the drive wheel with respect to the driven wheel in the power transmission path transmitting the power of the drive source.

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 refrigerator includes a plurality of storage compartments and an evaporator configured to generate cold air through heat exchange. A duct includes a plurality of channels to carry cold air to the plurality of storage compartments and a fan is configured to supply cold air generated by the evaporator to the plurality of channels. A cold-air adjuster includes a plurality of open or close members provided in the plurality of channels, to adjust the volume of cold air flowing into the plurality of storage compartments. An actuator is configured to interlock operation of one of the plurality of open or close members with operation of another of the open or close members.

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.
