Abstract
Provided is a door for a refrigerator. The door includes an outer door manufactured by pressing and deforming a metal sheet. The outer door includes a first surface, second to fifth surfaces extending from the first surface, and a plurality of flanges extending from the second to fifth surfaces. The first to fifth surfaces are integrated with each other and defined based on the pressing and deforming of the metal sheet. A door liner is coupled to surfaces of the plurality of flanges of the outer door, and an insulation material is disposed in a space defined between the door liner and the outer door.
Claims9
A method for manufacturing a door, the method comprising:
- pressing and deforming a metal plate to manufacture an outer door of which a front surface, both side surfaces, a top surface, and a bottom surface are integrated with each other;
- removing a mold fixing part that fixes the outer door during the pressing and deforming of the metal plate;
- bending edges of the side surfaces, the top surface, and the bottom surface of the outer door to define flanges at the side surfaces, the top surface, and the bottom surface of the outer door;
- and
- after defining the flanges at the side surfaces, the top surface, and the bottom surface of the outer door, injecting a foam agent into a space defined by the outer door.
