Description

Technical Field

[0001] The invention belongs to the technical field of refrigerator display, and in particular relates to a 3D diffraction display box cover and a manufacturing process thereof. Background Art

[0002] At present, the unique new technologies in terms of preservation, sterilization, humidity control, air circulation control, and variable temperature control inside refrigerators have become the core technologies for manufacturers' market competition. How to fully highlight the technologies owned by their own brands and explicitly display them to consumers to attract their attention has become the focus of breakthroughs in new materials and new processes.

[0003] Existing visualization designs of refrigerator functions mostly use processes such as "silk screen printing, hot stamping, lamination, and transfer printing" to promote 3D diffraction patterns and texts on the surface of functional parts. The appearance effects of the products are different, but they are all flat 2D effects.

[0004] In addition, the lighting design of the refrigerator's functional visualization design is mostly an atmosphere light design, which is mainly for decoration and rendering effects, and does not have the function of displaying the activation and operation of the refrigerator's related functions. After setting a function, consumers have no intuitive perception of whether the function is activated and its operating status.

[0005] With the continuous development of optical coating technology, the surface coating treatment of transparent substrates and the principle of optical diffraction, combined with lighting control technology, can not only display functions as three-dimensional effects, but also intuitively display the operating status of functions.

[0006] At the same time, with the continuous development of lighting technology, the breathing light can gradually change from bright to dark or from dark to bright under software control rules, which feels like breathing. It can be used as various status indicators such as operation indicator light and information prompt light to improve functional perception.

[0007] The present invention provides a 3D diffraction display box cover and a manufacturing process thereof. A first coating layer coated on the back of a function box cover is an optical medium capable of transmitting optical fiber. A 3D diffraction pattern is laser-engraved on the first coating layer. The slit diffraction generated by the 3D diffraction pattern lines of the 3D diffraction pattern coated inside the transparent function box cover is transmitted to the outer surface of the function box cover to form a diffraction screen, thereby generating a multi-layer 3D visual effect. Summary of the invention

[0008] The purpose of the present invention is to provide a 3D diffraction display box cover and its manufacturing process, wherein the first coating layer coated on the back of the functional box cover is an optical medium capable of transmitting optical fiber, and a 3D diffraction pattern is laser engraved on the first coating layer.
