Freezing compartment air flow system of refrigerator

摘要

Disclosed is a refrigerator for uniformly cooling a freezing compartment through the use of outlets and a passageway at the inner portion of the base plate of the freezing compartment. The base plate is provided with an upper plate having a plurality of air outlets and a lower plate having a plurality of protrusions for supporting the upper plate. The lower plate is manufactured from an insulating material. A chilled air passageway for exhausting the chilled air from the freezing compartment is formed between the upper and lower plates. The chilled air generated by an evaporator flows into the freezing compartment through a main-inlet and sub-inlets formed at the rear wall of the freezing compartment, and is exhausted through a main air exhausting outlet and the sub-outlets formed in the base plate. The chilled air exhausted through the sub air exhausting outlets flows through the chilled air passageway, that is formed in the base plate and joins the chilled air from the main air exhausting outlet. By using suboutlets in the base plate to improve the out flow of the exhausted air, the freezing compartment is cooled uniformly and the cooling efficiency of the refrigerator is increased.
