Document Type and Number:
WIPO Patent Application WO/2019/128718
Kind Code:
A1
Abstract:
Provided is a branched air supply device (400) and a refrigerator (10).
The branched air supply device (400) comprises: a shell (410) having a peripheral wall portion (412), with the peripheral wall portion (412) being provided with a plurality of air supply ports (411); a plurality of baffles (420), with each of the baffles (420) being rotatably mounted at one of the air supply ports (411); a plurality of transmission assemblies, with each of the transmission assemblies being provided with a rotating member (430) and a first transmission mechanism, and each of the first transmission mechanisms being configured to transmit a rotational motion of a corresponding rotating member (430) to one of the baffles (420), so that the baffle (420) is at rest or rotates; and a driving device having a driving source (450) and a second transmission mechanism, with the second transmission mechanism being configured to transmit one motion, output by the driving source (450), to the plurality of rotating members (430), so that each of the rotating members (430) is at rest or rotates. The device can uniformly and conveniently adjust the flow path and flow rate of cold air, and rationally distributes the cold air, thus enhancing the freshness-maintaining performance and operating efficiency of the refrigerator (10). Moreover, the device has the advantages of simple control, convenient adjustment, a fast adjustment speed, and a high adjustment accuracy.
