Refrigerator

Abstract

A refrigerator, with an inner casing forming a drawer type storage compartment and a drawer unit being received in and combined with the drawer type storage compartment, the refrigerator having: at least a pair of rail units provided between the inner casing and the drawer unit enabling the drawer unit to slide against the inner casing; a support part positioned at the inner casing, supporting the rail unit, and preventing the rail unit from moving upward and downward; and a combining part combining the rail unit with the support part, the combining part enabling the support part to move relative to the rail unit in a direction approximately perpendicular to a surface of the inner casing.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of Korean Patent Application No.10-2005-0097639, filed on Oct. 17, 2005, and Korean Patent Application No.10-2005-0133858, filed on Dec. 29, 2005, in the Korean Intellectual Property Office, the disclosures of which are 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 drawer type storage compartment. [0004] 2. Description of the Related Art [0005] In general, the refrigerator is an apparatus for storing food at a low temperature, and having a main body cabinet in which one or more storage compartments are formed; doors for opening / closing the storage compartments, respectively; and a refrigerating apparatus provided in the main body cabinet for refrigerating each storage compartment. Food is stored in each storage compartment. [0006] The main body cabi...

AI Technical Summary

Benefits of technology

[0012] Accordingly, it is an aspect of the present invention to provide a refrigerator that can maintain constantly a space between the rail units though an inner casing is contracted at a low temperature.

[0014] According to an aspect of the present invention, the support part has a first combining hole positioned thereon; the rail unit has a second combining hole positioned thereon to correspond to the first combining hole; and the combining part has a screw passed through the second combining hole and combined with the first combining hole, the screw having a body portion having a thread to combine with the first combining hole, a head portion radially extended from an axial direction of the screw, and a rail guide portion formed between the body portion and the screw head portion enabling the support part to move relative to the rail unit.

Problems solved by technology

On the other hand, since the door plate and / or the combining member connecting a pair of rail units are configured to have regular intervals and are not influenced by the contraction of the inner casing and the foam member, the drawer type door unit has a problem in that a distance between the rail units over their overall length can not be maintained constantly, and a disposition shape of the rail units is deformed into a trapezoid shape or a lozenge shape, and so a sliding movability of the drawer type door unit decreases.
