Title:
AIR DUCT ASSEMBLY FOR REFRIGERATOR AND REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2019/137091
Kind Code:
A1
Abstract:
Provided are an air duct assembly of a refrigerator and a refrigerator. The refrigerator (1) is provided with an evaporator chamber (23) that supplies a cooling airflow to a refrigerating chamber (21) and a freezing chamber (22). A double-layer air duct structure for communicating the evaporator chamber (23) and the freezing chamber (22) is formed in the air duct assembly (10) to controllably transport at least a portion of the cooling airflow in the evaporator chamber (23) to the freezing chamber (22). The double-layer air duct structure comprises an air-taking duct (11) on a rear side and directly communicating with the evaporator chamber (23), and a freezing air duct (12) on a front side and directly communicating with the freezing chamber (22). A path connecting the air-taking duct (11) with the freezing air duct (12) is provided with a freezing damper (14) which is opened and/or closed in a controlled manner, so as to open and/or close the communication between the air-taking duct (11) and the freezing air duct (12), and to control the amount of the cooling airflow sent to the freezing chamber (22). Therefore, the cooling airflow in the air-taking duct (11) is prevented from affecting the freezing chamber (22), so that the freezing chamber (22) can be further controlled or even used as the refrigerating chamber (21).
