Title:

AIR-COOLED REFRIGERATOR

Document Type and Number:

WIPO Patent Application WO/2019/129064

Kind Code:

A1

Abstract:

An air-cooled refrigerator (100), comprising an air supply duct (130). A plurality of raised lines (130a) protruding towards an inner space of the air supply duct (130) is formed on an inner wall of the air supply duct. The raised lines (130a) extend along the extension direction of the air supply duct (130), and the plurality of raised lines (130a) is distributed in parallel along the circumferential direction of the inner wall of the air supply duct (130), so that a groove-like flow channel is formed by two adjacent raised lines (130a), to disperse the airflow in the air supply duct (130), thereby reducing airflow flow noise and improving sound quality of the refrigerator.
