Title:
REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2022/168347
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a refrigerator using a centrifugal fan, with an improved flow of cold air discharged from a discharge port. This refrigerator comprises: a refrigerating evaporator 14a; an upper discharge port 122; an upper guide duct 127 that connects the refrigerating evaporator 14a and the upper discharge port 122; and a refrigerating centrifugal fan 9a that blows air from the refrigerating evaporator 14a to the upper discharge port 122. The upper guide duct 127 extends progressively in the direction of the swirling component of the refrigerating centrifugal fan 9a from the refrigerating evaporator 14a toward the upper discharge port 122. The upper guide duct 127 has: a first front discharge port 125 with a longitudinal center further towards the anti-swirling component side than the centerline of the flow path of the upper guide duct 127; a first tributary duct 129 branching out from the upper guide duct 127 toward the anti-swirling component side; and a first tributary discharge port 123 from which air flowing through the first tributary duct 129 is discharged.
