Description

Refrigerator cover structure

Technical Field

The utility model relates to a refrigerator heat preservation technical field especially relates to a refrigerator lid structure.

Background

The existing refrigerator cover generally adopts a structural form that an outer layer is a metal sheet metal shell and an inner layer plastic lining, and polyurethane foaming is adopted for filling in the middle. However, in the actual production process, the metal sheet metal shell is easy to deform due to the expansion and contraction of the polyurethane foam material during the foaming process or the expansion and contraction of the refrigerator during the use process, and the heat insulation effect of the existing refrigerator cover is basically close to the heat insulation effect of the polyurethane foam layer, so that the heat insulation effect is general, and the heat insulation performance needs to be further improved.

SUMMERY OF THE UTILITY MODEL

Therefore, the to-be-solved technical problem of the utility model is to overcome the above-mentioned not enough that current refrigerator lid structure exists, and then provide one kind and can avoid the metal sheet metal casing of refrigerator lid to warp to can further improve the refrigerator lid's heat preservation performance's refrigerator lid structure.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the refrigerator cover structure comprises a metal sheet metal shell and a plastic inner layer arranged on the inner side of a refrigerator, wherein the metal sheet metal shell and the plastic inner layer are filled with a polyurethane foaming layer, a felt layer is arranged between the polyurethane foaming layer and the metal sheet metal shell, and the felt layer is adhered to the inner side surface of the metal sheet metal shell.

Preferably, a layer of kraft paper is arranged between the felt layer and the polyurethane foam layer as a spacing layer.

Preferably, the kraft paper is adhesively attached to the batt layer.

Preferably, the felt has a thickness of 1.5-5 mm.

Preferably, the felt is adhered to the metal sheet shell through adhesive sticker.

Preferably, the polyurethane foam layer adheres the plastic inner layer and the kraft paper through foaming.

Preferably, the plastic inner layer is a blister plastic inner layer.

The utility model has the advantages that:

the utility model discloses an ice lid structure, medial surface through at the metal sheet metal shell sets up the one deck felt layer, can improve the shock-absorbing capacity of metal sheet metal component greatly, the polyurethane foaming layer can effectively avoid causing the problem of the metal sheet metal component shell of ice lid because of expend with heat and contract with cold's effect carrying on the foaming in-process, and can improve and promote the metal sheet metal component in time to recover after receiving external pressure deformation, and through set up the one deck felt layer in metal sheet metal shell inboard, can further reduce the coefficient of heat conductivity of ice lid, further improve the heat preservation effect of ice lid.

Drawings

In order that the present invention may be more readily and clearly understood, reference is now made to the following detailed description of the invention taken in conjunction with the accompanying drawings, in which:

fig. 1 is a schematic structural diagram of the refrigerator lid structure of the present invention.

The reference numbers in the figures denote:

1-a metal sheet shell; 2-plastic inner layer; 3-a polyurethane foam layer; 4-felt layer; 5-kraft paper;

Detailed Description

Referring to fig. 1, a refrigerator cover structure comprises a metal plate shell 1 and a plastic inner layer 2 arranged on the inner side of a refrigerator, wherein the metal plate shell 1 and the plastic inner layer 2 are filled with a polyurethane foaming layer 3, a felt layer 4 is arranged between the polyurethane foaming layer 3 and the metal plate shell 1, and the felt layer 4 is adhered to the inner side surface of the metal plate shell 1. The utility model discloses an ice lid structure, medial surface through at the metal sheet metal shell sets up the one deck felt layer, can improve the shock-absorbing capacity of metal sheet metal component greatly, the polyurethane foaming layer can effectively avoid causing the problem of the metal sheet metal component shell of ice lid because of expend with heat and contract with cold's effect carrying on the foaming in-process, and can improve and promote the metal sheet metal component in time to recover after receiving external pressure deformation, and through set up the one deck felt layer in metal sheet metal shell inboard, can further reduce the coefficient of heat conductivity of ice lid, further improve the heat preservation effect of ice lid.

The refrigerator lid structure of this embodiment is in felt layer 4 with be provided with one deck kraft paper 5 between the polyurethane foaming layer 3 as the spacer layer, set up the kraft paper and can play certain thermal-insulated effect on the one hand, the foremost is that the kraft paper forms a flaky supporting layer outside the felt layer, can form comparatively even extrusion to the felt layer when polyurethane foaming to be convenient for foaming in-process lateral flow, and then improve the fillibility and the homogeneity of polyurethane foaming layer.

The kraft paper 5 and the felt layer 4 of this embodiment pass through the glue solution bonding connection, the preferred 1.5-5 millimeters of thickness of felt layer 4, the felt layer pass through the non-setting adhesive with the adhesion of metal sheet metal shell 1.

This embodiment plastics inlayer 2 is the plastic uptake plastics inlayer, polyurethane foam layer 3 will through the foaming plastics inlayer 2 with 5 adhesions of kraft paper, and then lead to metal panel beating shell, felt layer, kraft paper, polyurethane foam layer, the plastics inlayer formation overall structure with the refrigerator lid.

The above-mentioned embodiments are only for explaining the technical solution of the present invention in detail, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art should understand that all the modifications and substitutions based on the above-mentioned principle and spirit should be within the protection scope of the present invention.
