[0013] As a further solution of the utility model: the reinforcing ribs are distributed in a criss-cross pattern on the back of the lining box substrate, and are arranged in a circle along the edge of the lining box substrate.

[0014] As a further solution of the utility model: a filling glue is applied on the back side of the lining box substrate, and the thickness of the filling glue is equal to the height of the reinforcing rib.

[0015] Beneficial effects of the utility model:

[0016] (1) The utility model combines the pre-embedded lining boxes with different functions such as the wiring harness terminal lining box, evaporator fixing buckle, air duct fixing screw column, air duct clip, etc. in the existing refrigerator into one injection molded part, with the back side coated with glue.

[0026] The liner box substrate 1 and the components arranged on the liner box substrate 1 are all formed by one-piece injection molding, and a plurality of embedded liner boxes with different functions are combined into one injection molded part, thereby ensuring the overall installation of different components, providing a high degree of overall modularization of the internal structure of the refrigerator and improving the installation efficiency of refrigerator production.

[0027] The upper surface of the lining box substrate 1 is provided with a covering adhesive 2, and the covering adhesive 2 has the same appearance and structure as the lining box substrate 1 and corresponds to the components on the lining box substrate 1.

[0028] The lining box substrate 1 is provided with a plurality of substrate through grooves 8, and a plurality of pre-embedded lining box components are integrated on the lining box substrate 1. Therefore, in order to ensure the stability of the overall installation of the lining box substrate 1, the overall weight of the lining box substrate 1 is effectively reduced by providing the substrate through grooves 8, which facilitates its stable installation, and at the same time reduces the overall material usage of the injection molded lining box substrate 1, thereby saving production costs.

[0029] The lower part of the lining box substrate 1 is provided with an avoidance groove 9 for avoiding refrigerator components. Since the lining box substrate 1 needs to be installed on the back of the refrigerator 100, and other components are installed on the refrigerator 100, while ensuring that the components on the lining box substrate 1 are integrated and installed without interfering with other components, the avoidance groove 9 is provided to avoid other components, thereby ensuring that the lining box substrate 1 and other components are installed in an orderly and stable manner on the back of the refrigerator 100.

[0031] The back of the lining box base plate 1 is provided with reinforcing ribs 10, and the provision of the reinforcing ribs 10 can effectively ensure the overall strength and rigidity of the lining box structure.

[0032] The reinforcing ribs 10 are crisscrossed on the back of the lining box substrate 1 and are arranged in a circle along the edge of the lining box substrate 1. Reinforcing ribs 10 are arranged at the edges of the avoidance grooves 9 and the substrate through grooves 8, thereby improving the integrity of the lining box substrate 1 and ensuring stability when the components are installed.

[0033] The back of the lining box substrate 1 is coated with a filling glue 11, and the thickness of the filling glue 11 is equal to the height of the reinforcing rib 10. By setting the filling glue 11 to completely adhere to the back of the lining box substrate 1, on the one hand, the overall strength of the lining box mechanism is ensured, and on the other hand, the surface aesthetics of the lining box mechanism is improved.
