Description

Technical Field

[0001] This utility model belongs to the field of household appliance technology, and in particular relates to a decorative panel for attaching to the surface of a refrigerator air duct panel. Background Technology

[0002] Refrigerators have become an essential household item in modern homes. At the same time, frost-free refrigerators have gradually replaced direct-cooling refrigerators. On the back of the refrigerator compartment of a frost-free refrigerator, there is usually an air duct. In order to improve the product's quality, refrigerator manufacturers often attach a decorative panel to the front panel of the air duct to enhance the product's appearance and increase its selling points.

[0003] Air duct decorative panels are generally made of plastic, with a base material of PS or ABS, and a thickness ranging from 0.5-2mm. The surface features various decorative textures. There are two existing methods for attaching these panels to the refrigerator's air duct panel: ultrasonic welding and tape bonding. Ultrasonic welding requires specialized welding equipment, and the base material of the decorative panel and the air duct panel must be the same material; otherwise, the weld strength will be affected. Furthermore, to avoid deformation and appearance defects caused by the heat of welding, the decorative panel thickness generally needs to be at least 2mm, increasing product costs. The other method, tape bonding, typically involves pre-applying tape to the air duct panel before attaching the decorative panel. During the bonding process, due to the thinness of the decorative panel, problems such as uneven bonding, air entrapment, and misalignment can easily occur, and the bonding efficiency is relatively low.

[0042] In each group of 40 positioning blocks, the number of positioning blocks 4 can be adjusted according to the actual situation.

[0043] like Figures 1 to 3 As shown, in some embodiments of this utility model, the adhesive layer 2 is PET double-sided tape.

[0044] like Figures 1 to 3 As shown, in some embodiments of this utility model, several adhesive layers 2 are arranged linearly and equally spaced on the top surface of the refrigerator air duct component 1.

[0045] like Figures 1 to 3 As shown, in some embodiments of this utility model, the distance between two adjacent adhesive layers 2 is 150-300mm.

[0046] like Figures 1 to 3 As shown, in some embodiments of this utility model, the length of the adhesive layer 2 is basically the same as the width of the refrigerator air duct component 1.

[0047] like Figures 1 to 3 As shown, in some embodiments of this utility model, the adhesive layer 2 can be provided in two groups, namely group A and group B; the adhesive layer 2 in group A is provided as two layers, and the two adhesive layers 2 are respectively attached to the upper end and the lower end of the top surface of the refrigerator air duct component 1; the adhesive layer 2 in group B is provided as multiple layers, and the multiple adhesive layers 2 are provided between the two adhesive layers 2 in group A, and are arranged linearly at equal intervals, and the straight line containing the long side of the adhesive layer 2 in group A is perpendicular to the straight line containing the long side of the adhesive layer 2 in group B.

[0048] like Figures 1 to 3 As shown, in some embodiments of this utility model, the bonding process of the bonding fixture for attaching decorative panels to the surface of a refrigerator air duct panel specifically includes the following steps:
