Device for self-adaptive regulation of air volume and refrigerator having same

Abstract

Provided are a device () for self-adaptive regulation of air volume and a refrigerator () having the same. The regulating device () comprises: a drainage and air guide cavity (), arranged on the back of a freezing chamber () of a refrigerator, the drainage and air guide cavity () comprising a funnel-shaped air collecting cavity () and a conical air outlet cavity () connected to the funnel-shaped air collecting cavity (), an outlet of the conical air outlet cavity () facing a refrigerating chamber; a drainage tongue (), provided in the conical air outlet cavity () so as to create a first outlet duct () and a second outlet duct () within the conical air outlet cavity (), an inlet () of the first outlet duct () being located on an extension line of a left side wall () of the funnel-shaped air collecting cavity () and an inlet () of the second outlet duct () being located on an extension line of a right side wall () of the funnel-shaped air collecting cavity (); and a fan () arranged inside of the funnel-shaped air collecting cavity (). By rotating the fan (), cold air is conveyed through the first outlet duct () and the second outlet duct () and into a refrigerating chamber () under the guide of the left side wall () or right side wall () of the funnel-shaped air collecting cavity ().
