Refrigerator

Abstract

A refrigerator capable of adjusting a discharge position and a quantity of cold air discharged into the refrigerator. The refrigerator includes an inner panel installed at a rear surface of a storage chamber and having cold air outlets for forming a cooling channel. The refrigerator also includes a variable duct installed at one of the cold air outlets such that the variable duct can move back and forth to vary a length of the cooling channel, and a plurality of cold air distribution holes formed in the variable duct.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of Korean Patent Application No. 2004-79623, filed Oct. 6, 2004, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a refrigerator, and more particularly, to a refrigerator, having a cooling channel which is varied to uniformly distribute cold air into a storage chamber. [0004] 2. Description of the Related Art [0005] Generally, a refrigerator includes a cooling channel provided at a rear portion of an inside of a storage chamber to circulate cold air into the storage chamber, an air blast fan installed in the cooling channel, and an evaporator installed in the cooling channel to cool the circulated air. The refrigerator further includes a plurality of cold air outlets formed through a rear surface of the storage chamber such that the cold air outle...

AI Technical Summary

Benefits of technology

[0008] Accordingly, it is an aspect of the present invention to provide a refrigerator, in which a discharge position and quantity of cold air are adjusted, thereby facilitating uniform distribution of the cold air into a storage chamber and having a simple configuration.

[0016] Further, The channel adjusting device may increase a width of the channel in the variable duct when the variable duct is pulled forward to increase a length of the cooling channel, and decrease the width of the channel in the variable duct when the variable duct is pushed backwards to decrease the length of the cooling channel.

[0019] Moreover, protrusions may be installed between the first and second air guide members in the variable duct, to prevent the first and second air guide members from being constricted toward a central portion of the variable duct.

Problems solved by technology

The inside of the storage chamber of the above refrigerator is divided by a plurality of racks, and positions of the cold air outlets are fixed to supply the cold air to spaces between the individual racks, when the quantities of goods stored on the racks differ from each other or the cold air outlets are covered with the stored goods, a difference of temperatures between the spaces, between the racks in the storage chamber is generated, thereby making it difficult to uniformly cool the storage chamber.

Since the cold air distributing device of the above refrigerator includes a driving motor and a driving cam to adjust a direction of distributed cold air, the refrigerator has a complicated configuration, thereby requiring high production costs.
