[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1-4 As shown in the figure, this utility model embodiment proposes a refrigerator main control board mounting assembly, including:

[0025] The main control box 1 has mounting plates 4 fixedly installed on both sides. The mounting plates 4 have through-holes and are used to install the main control box 1 inside the refrigerator. The main control box 1 contains a main control board body 5. The main control board body 5 has positioning holes 6 through-holes at its four corners and is used to position the main control board body 5.

[0026] The main control box 1 is provided with a mounting cover 2. A hinge 3 is fixedly installed on one side of the main control box 1, and the other side of the hinge 3 is fixedly installed on one side of the mounting cover 2, so that the mounting cover 2 can be rotatably connected to the main control box 1 through the hinge 3.
