AI Technical Summary

Technical Problem

The refrigerator inner liner is prone to shrink when the temperature changes, resulting in a decrease in structural strength and poor insulation effect. Currently, felt is used in the industry to enhance the strength of the inner liner wall but the cost is high.

Method used

A mesh glass fiber material layer is used to attach it to the surface of the inner liner wall, and a polyurethane foam insulation layer is formed by injecting material foam. The mesh glass fiber material layer separates the foam and makes it closely bond with the inner liner wall.

Benefits of technology

It improves the insulation effect and strength of the refrigerator inner liner, reduces the shrinkage performance of the inner liner. At the same time, due to the use of low-cost mesh fiberglass material, manufacturing costs are significantly saved.

Abstract

The utility model discloses a netlike glass fiber material enhanced anti-shrinkage inner container, which relates to the technical field of refrigerator inner containers, and the manufacturing process of the inner container comprises the following steps: attaching a netlike glass fiber material layer on the outer side surface of the inner container wall; the inner container wall, the refrigerator shell and electric parts of the refrigerator are pre-assembled into a whole, a reserved space of the heat preservation layer is formed between the inner container wall and the refrigerator shell, and the net-shaped glass fiber material layer is located in the reserved space; and injecting a thermal insulation material into the reserved space, and after foaming of the thermal insulation material is completed, obtaining the netted glass fiber material enhanced anti-shrinkage liner. During foaming, due to the separation of the net-shaped glass fiber material, foam is firstly filled in a plurality of grids of the net-shaped glass fiber material, so that the foam layer is prevented from being in contact and fit with the whole plate of the inner container wall, but is in contact and fit with a plurality of square block sites, and the combination between the foam layer and the inner container wall is tighter; meanwhile, the glass fiber mesh material layer also directly enhances the strength of the inner container wall, so that the inner container wall has stronger anti-shrinkage performance.
