Benefits of technology

[0023]In an aspect of one or more embodiments, the manufacturing cost is reduced by manufacturing a frame using a PCM steel plate instead of aluminum which is more expensive than PCB steel.
[0024]In addition, one or more embodiments may remove a post treatment that needs to be performed on a conventional aluminum frame after extrusion.
[0025]In addition, the process of manufacturing a frame is simplified, and the assembly structure of a door is simplified, thereby enhancing the reliability on the product quality.
[0026]In addition, a door frame may be integrally formed with a grip groove to open / close a door, thereby removing a need for a protruding knob.

Problems solved by technology

In general, frames are manufactured by extruding aluminum in a desired form, but the aluminum used in the extrusion is more expensive than other metals.

Abstract

A refrigerator door includes a front surface panel and a rear surface panel configured such that a foam space is provided between the panels, first and second frames configured to form each side surface of the door and to which the two panels are supportedly attached, an upper cap and a lower cap configured to form upper and lower surfaces of the door, respectively, and thermal insulating material which is provided in the foam space to couple the front surface panel, the rear surface panel, the first frame, the second frame, the upper cap, and the lower cap to one another, wherein each of the first frame and the second frame is formed by sequentially introducing a steel plate coil having a predetermined thickness and width into a predetermined number of roll forming members.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the priority benefit of Korean Patent Application No. 2011-0060102, filed on Jun. 21, 2011 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.BACKGROUND[0002]1. Field[0003]Embodiments relate to a door of a refrigerator.[0004]2. Description of the Related Art[0005]A refrigerator is an apparatus which is provided with a storage compartment, and configured to keep food fresh by providing cool air through a cooling cycle. The storage compartment has a front surface open. The front open surface is open / closed by a door that is rotatably installed on a body.[0006]A front surface panel forming the external appearance of a door is formed using tempered glass to improve cognitive quality. Frames forming the framework of the door are configured to support the front surface panel. Each of the frames includes metal to stand the expansion pressure of a forming agent inside th...
