Document Type and Number:
WIPO Patent Application WO/2018/205383
Kind Code:
A1
Abstract:
A refrigerator and a single-system air suction duct thereof, the refrigerator comprising: a first refrigeration compartment (1) and a second refrigeration compartment (2), comprising an air duct panel (3) which is disposed at one side of the first refrigeration compartment (1) so as to define a heat exchange cavity with a rear side wall; a centrifugal fan (4), which is disposed within the heat exchange cavity, the heat exchange cavity being provided with an air inlet (5), and the air inlet (5) being in communication with the first refrigeration compartment (1) and the second refrigeration compartment (2) respectively; an annular evaporator (8), which covers an outer circumferential surface of the centrifugal fan (4); an air outlet (12) of the first refrigeration compartment, which is disposed on the air duct panel (3) and which is in communication with a circumferential outer space of the annular evaporator (8); an air supply duct (6) of the second refrigeration compartment, which communicates with the circumferential outer space of the annular evaporator (8) and which extends to the second refrigeration compartment (2) so as to supply air to the second refrigeration compartment (2). The refrigerator and the single-system air suction duct thereof increase the volumetric efficiency, heat exchange efficiency, and refrigeration capabilities of the refrigerator, while reducing costs.
