Abstract

A sealing structure for a refrigerator comprises a blocking member provided inside an air dam having a predetermined width between a refrigerator cabinet and a door liner of a door, for preventing convection in the air dam, so that convection in the air dam is prevented and thus external heat is prevented from being introduced into a storage compartment through the air dam.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a refrigerator, and particularly, to a sealing structure for a refrigerator capable of effectively preventing external heat from being introduced into a storage compartment by being provided between a refrigerator cabinet and a door. [0003] 2. Description of the Background Art [0004] In general, a refrigerator is a device for chilling or freezing items stored in a storage compartment by circulating cool air, generated by a refrigerating cycle, inside the storage compartment. The refrigerator includes a cabinet having a storage compartment; and a door installed at the cabinet, for opening and closing the storage compartment, and a gasket installed between the cabinet and the door, for preventing introduction of external heat into the storage compartment. [0005] As shown in FIGS. 1 and 2, the conventional refrigerator includes a cabinet (C) forming a storage compartment (F) therein, co...
