Refrigerator backplate

Abstract

The invention discloses a back board for a refrigerator, which is of hollow PP board, and can either be in a concave-back structure with a plurality of folded marks after foam forming, or be in a structure connected with the top plate after foam forming. The invention effectively takes use of the advantages of hollow PP boards such as the non-toxicity, the no smell, the light weight, the resistance to impact, the resistance to damp, the resistance to corrosion, the proofness to static, and the easy processing, etc.; the back board of hollow PP board can successfully replace the back board and back top plate of metallic material, guarantee the overall outline quality of the refrigerator, greatly reduce the cost; the product is of light weight, resistant to impact and corrosion, highly resistant to static, is easy to process, and good for environmental protection.

Description

technical field

[0001] The invention relates to the technical field of refrigerators, in particular to a refrigerator rear panel. Background technique

[0002] In the prior art, the back plate or the rear top plate of the refrigerator is generally made of metal material, which has high production cost, heavy weight, and poor electrostatic performance. As a new type of plastic packaging material, PP hollow plate, It has the advantages of non-toxic, odorless, light weight, impact resistance, moisture resistance, corrosion resistance, anti-static, easy to process, etc. It is used to make the back plate of the refrigerator, which can not only reduce the cost of the bottom refrigerator, but also is conducive to environmental protection ; However, because the properties of PP hollow boards are significantly different from those of metal materials, when they are used to make structural parts such as refrigerator rear panels, problems such as poor appearance, bubble leakage, and cre...
