Description

Refrigerator air duct based on glass luminous decorative painting and its production process

technical field

The invention belongs to the technical field of refrigerator air ducts, and particularly relates to a refrigerator air duct based on glass luminous decorative paintings and a manufacturing process thereof.

Background technique

At present, the volume of the refrigerator compartment of high-end refrigerators is constantly increasing, and the lighting of large-area light sources on the back of the refrigerator compartment has become a development trend. However, most of the current lighting sources use PMMA light guide plates and PS diffusers to achieve surface light source lighting, and large-area surface light sources only play the role of illuminants. Single function, lack of aesthetics and personalization.

The process plan of the PMMA surface light source used in the refrigerator industry, its lighting carrier is a multi-layer structure, which requires reflective paper, PMMA board, diffuser film and film, etc. The layers are sealed with double-sided tape, and the material is easy to wrinkle and interlayer. There are easily empty drums and dust, debris, and water droplets that affect the appearance; the surface light source often appears water in the refrigerator residual frost and frost blocking experiments. The structure is relatively complex, the requirements for the assembly process are high, and the lighting guide structure is relatively complex.

In the field of home appliances, the frameless shape has become an important pursuit point in the design of the appearance and structure of home appliances because of its simple and elegant appearance. The frameless design style has become an important development trend of high-end refrigerators. The original PMMA surface light source due to its material characteristics Can't get rid of the border structure. The water absorption rate of glass material is much lower than that of PMMA or MS material, the coefficient of expansion is extremely low, and it is resistant to high temperature. It can realize ultra-narrow frame or even frameless design, and the strength of glass is more than 26 times that of PMMA. The supporting effect of glass itself on lighting devices, The frame and backplate can be omitted.

Further, if a glass surface light source is used to achieve lighting, the glass needs to be made of special special glass. Ordinary glass cannot achieve a uniform light guide effect on the whole large surface, and dark areas will be generated in parts far away from LEDs, and special special glass is expensive.
