KR960024163A - Cold duct of the refrigerator - Google Patents

Abstract

The present invention relates to a cold air duct of a refrigerator, and more particularly, to a cold air duct of a refrigerator having a structure capable of smoothly supplying and returning cold air, while its purpose is to facilitate cold air circulation so that cold air return is not unreasonable. It is to provide a cold air duct of the refrigerator having a structure capable of maximizing the effective contents of the refrigerator by making the thickness of the trimming plate as thin as possible, the configuration is disposed on the front of the evaporator to block the evaporator and blower fan installation of the rear part of the freezer compartment. And a blocking plate having a freezing chamber cold air supply hole penetratingly formed at an upper predetermined position; A blocking plate disposed at a rear side of the evaporator to form a refrigerating chamber cold air supply passage for supplying cold air to the refrigerating chamber by the blower fan and having a cold air inlet hole formed therethrough; A freezer cold air return duct having a cold air suction port formed at a lower surface of the front end of the freezer compartment in a refrigerator trimmer and connected to the evaporator mounting unit in communication with the evaporator installation unit; A refrigerator compartment cold air return duct having a cold air inlet formed through a ceiling portion of the front end portion of the refrigerator compartment and arranged in a lower portion of the freezer compartment cold return duct to be connected to the evaporator installation unit in a refrigeration plate of the refrigerator; The refrigerator compartment consists of a refrigerator compartment cold air supply duct which is connected to communicate with the lower surface of the refrigerator air supply passage and communicates with the refrigerator compartment and integrally has a cold air outlet protruding at an upper predetermined position of the refrigerator compartment to supply the cold air into the refrigerator compartment. In the cold air duct of the refrigerator, the refrigerating compartment cold air return duct is connected to the lower portion of the refrigerating compartment and the evaporator installation portion is characterized in that it is built in the rear wall of the refrigerator in order to return the return cold air in the refrigerating compartment.
