Machining method of refrigerator door plate

Abstract

The invention discloses a machining method of a refrigerator door plate. The machining method comprises the following steps: S1, material selection: a proper refrigerator door board is selected, steam fumigation disinfection is conducted on the plate, and washing and cleaning are then performed; S2, machining: after cleaning is completed, grooving machining is conducted on the board, and after grooving machining is conducted, a groove position is polished and modified; S3, heat preservation layer treatment: multiple layers of filling are arranged in a heat preservation layer, and the filler comprises sponge and a foamed plastic plate; and S4, gluing: the groove position is glued, and the heat preservation layer is pasted through the glue so that the heat preservation layer and the groove position are attached together. According to the method, the board is grooved, coordination grooves are formed in the grooves, the heat preservation layer is matched with the formed groove position and the coordination grooves, and then the glue is adopted for bonding so that the whole heat preservation layer can be conveniently replaced in the later period, the difficulty of upgrading of the heat preservation layer is reduced, it is guaranteed that the heat preservation performance of a refrigerator is maximized, the whole usage effect of the refrigerator is improved, and the service lifetime of the refrigerator is prolonged.

Description

technical field [0001] The invention relates to the technical field of refrigerator door panel production, in particular to a method for processing a refrigerator door panel. Background technique [0002] A refrigeration device that maintains a constant low temperature is also a civilian product that keeps food or other items in a constant low temperature and cold state. There are compressors, refrigerators or cabinets for freezing in the box, and storage boxes with refrigeration devices. The volume of household refrigerators is usually 20-500 liters. There are many types of refrigerators, which are generally classified according to their internal cooling, usage, climate environment, shape, and placement of cooling methods. Gas compression refrigerator: It relies on the heat absorption of low-boiling liquid refrigerant (such as Freon R12) to achieve the purpose of refrigeration, and then evaporates and compresses it with a compressor, and then makes it release heat and liq...

Problems solved by technology

[0003] The existing refrigerator door panels need to be filled with insulation layers inside the door panels during production. However, due to the rapid replacement of existing insulation materials, the traditional insulation layer installation is inconvenient to replace later, resulting in the failure of the entire refrigerator’s insulation performance. It is not conducive to prolonging the use effect and service life of the refrigerator, so we propose a processing method for refrigerator door panels
