Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator production and manufacturing, in particular to an anti-deformation structure of a corner of a water receiving tray groove of a refrigerator box. Background Art

[0002] The existing refrigerator box liner has a small rounded corner design at the water receiving tray, and no reinforcing ribs are added to the large surface. These design problems often lead to the box liner becoming thin or cracked during the vacuum forming process. During the foaming process of the box liner following the box body, the corner of the box liner at the water receiving tray often cracks, causing the box body to be scrapped.

[0003] To solve this problem, the production department often increases the thickness of the blister sheet to strengthen it, which leads to a significant increase in the cost of the box. In the process of increasing the thickness of the sheet, it is sometimes necessary to repeatedly adjust the blister process, resulting in low production efficiency. In addition, the corners of the water tray are weak, resulting in insufficient strength, and cracking sometimes occurs during user use, causing user complaints or machine returns and other risks.

[0007] As a further solution of the utility model: the box liner is formed by combining a plurality of irregular surfaces into one body, and the connection between the surfaces of the box liner are formed into rounded corners.

[0008] As a further solution of the utility model: the intersection of the rounded corners is formed as a first spherical corner, and reinforcing ribs are reinforced on the rounded corners in the box liner near the first spherical corners.
