AI Technical Summary

Technical Problem

Existing refrigerator designs embed reinforcing members for door hinges within fluid heat insulating material, requiring separate reinforcing members for different door designs, leading to increased costs due to the need for customized parts.

Method used

The refrigerator design positions reinforcing members above or below the door panel, avoiding embedding them in the fluid insulation material, allowing for shared use across various door designs.

Benefits of technology

This approach reduces costs by enabling the sharing of reinforcing members across different door designs, improving installation ease and reducing the need for customized parts.

Abstract

We provide a refrigerator that reduces costs by sharing door reinforcement components. [Solution] The refrigerator of the present invention comprises an upper hinge portion 70 having an upper hinge pin 72 and fixed to the insulated box body 1, and a refrigerator door 22 supported by the insulated box body 1 by the upper hinge portion 70. The refrigerator door 22 includes an upper hinge pin storage section 2212 in which the upper hinge pin 72 is housed, and a door panel 226 positioned on the opposite side of the upper hinge pin storage section 2212 from the insulated box 1. A reinforcing member 75 is provided to prevent the refrigerator door 22 from falling out of the insulated box 1 even if the upper hinge pin 72 comes out of the upper hinge pin storage section 2212, and the reinforcing member 75 is positioned above the upper end of the door panel 226.
