Document Type and Number:
WIPO Patent Application WO/2022/092975
Kind Code:
A1
Abstract:
The present invention relates to a refrigerator door having a vacuum insulation assembly (50) and a method for manufacturing same. In the present invention, a first door body (10) and a second door body (20) are coupled to each other to form the exterior of the door. In addition, a heat insulating space is formed between the first door body (10) and the second door body (20), and the vacuum insulation assembly (50) is installed in the heat insulating space. There is a sealed vacuum chamber inside the vacuum insulation assembly (50), and at least a portion of the edge of the vacuum insulation assembly (50) may be surrounded by a foam filled part (F). As such, in the present invention, the vacuum insulation assembly (50) is installed inside the refrigerator door, and the vacuum insulation assembly (50) has high insulation performance, and thus can replace the existing foam filled part (F), and therefore, the thickness of the refrigerator door can be reduced.
