[0042] Figure 1 This is a flowchart of an assembly method for a refrigerator main control board according to an embodiment of the present invention. The top of the housing 201 of the refrigerator 200 has a notch 202. See also Figure 1 The assembly method of the refrigerator main control board may include the following steps S102 to S108.

[0043] Step S102: Secure the deformable cover 203 to the notch 202 to cover the notch 202. In this step, the cover 203 can be secured to the notch 202 by adhesive or screws, or other methods may be used.

[0044] Step S104: Apply a force toward the interior of the housing 201 to the cover 203, causing the cover 203 in the notched area to recess toward the interior of the housing 201, forming the receiving box 206. In this step, a specific mold with a protruding structure can generally be used to apply the force toward the interior of the housing 201 to the cover 203. The protruding structure is aligned with the notch 202, and a force is applied toward the interior of the housing 201 to the cover 203, thereby forming the receiving box 206. A schematic diagram illustrating the recess of the cover 203 toward the interior of the housing 201 to form the receiving box 206 can be found in [reference needed]. Figure 2 , Figure 2 This is a schematic diagram of the structure of a refrigerator according to another embodiment of the present invention.

[0045] Step S106: Inject foam material into the housing 201. When the foam material filling is finished, stop applying force toward the interior of the housing 201 to the cover 203 in the gap area.

[0046] Step S108: Install the main control board 212 into the housing 206. A schematic diagram of the main control board 212 can be found in [reference needed].

[0047] In the assembly method of the refrigerator main control board in this embodiment, a deformable cover 203 is fixed at the notch 202 to cover the notch 202. A force is applied to the cover 203 toward the inside of the housing 201 so that the cover 203 in the notch area is recessed toward the inside of the housing 201 to form a receiving box 206. Foaming material is filled into the housing 201. When the foaming material filling is finished, the force applied to the cover 203 in the notch area toward the inside of the housing 201 is stopped. The main control board 212 is installed in the receiving box 206. This assembly method of the main control board 212 is easy to seal, has low requirements for sealing process and foaming mold precision, and is low in cost. It can effectively avoid the problem of foam overflow.

[0048] In one embodiment of the present invention, the step of fixing the deformable cover 203 at the notch 202 may include:

[0049] A frame 204 is fixed around the notch 202 of the housing 201;

[0050] The edge of the cover 203 is secured between the housing 201 and the frame 204.

[0051] In this embodiment, a frame 204 is fixed around the notch 202 of the housing 201, and the edge of the cover 203 is fixed between the housing 201 and the frame 204, which can more firmly fix the cover 203 at the notch 202. The frame 204 around the notch 202 of the housing 201 can be found in [reference needed]. Figure 4 , Figure 4 This is a schematic diagram of the structure of a refrigerator 200 according to another embodiment of the present invention. Figure 4 The diagram shows the view from the bottom to the top of the housing 201.

[0052] In one embodiment of the present invention, the covering 203 can be flocked fabric. Of course, the covering 203 can also be other covering materials that can achieve the above-mentioned functions. Flocked fabric has the advantages of strong three-dimensionality, soft feel, lifelike appearance, non-toxic and odorless, heat insulation and moisture protection, non-shedding, abrasion resistance, and smoothness, and can more naturally become integrated with the shell 201 of the refrigerator 200.

[0056] In one embodiment of the present invention, the edge of the main control board 212 is provided with at least one first fixing hole 207, and the bracket 205 has fixing posts 208 corresponding to the first fixing holes 207. The step of fixing the main control board 212 to the bracket 205 may include: passing a fastener through the first fixing hole 207 and inserting it into the fixing post 208 to fix the main control board 212 to the bracket 205.

[0057] In this embodiment, the main control board 212 is fixed to the bracket 205 by fasteners passing through the first fixing hole 207 and inserted into the fixing post 208. This method allows for relatively easy disassembly and installation of the main control board 212. Alternatively, clips or adhesive can be used to fix the main control board 212 to the bracket 205. Multiple first fixing holes 207 can be present and evenly distributed along the edge of the main control board 212.

[0058] In one embodiment of the present invention, after the step of placing the main control board 212 in the receiving box 206, the method may further include: fastening the protective cover 209 onto the notch 202 to cover the receiving box 206.

[0059] In this embodiment, by attaching the protective cover 209 to the notch 202 to cover the receiving box 206, dust accumulation in the receiving box 206 can be prevented, thereby keeping the main control board 212 clean. The protective cover 209 can be fixed to the housing 201 with fasteners. A schematic diagram of the protective cover 209 can be found in [reference needed]. Figure 5 , Figure 5 This is a schematic diagram of the structure of a refrigerator 200 according to another embodiment of the present invention.

[0060] In one embodiment of the present invention, the step of fixing the frame 204 around the notch 202 of the housing 201 may include:

[0061] A frame 204 is fixed around the notch 202 on the inner surface of the housing 201 so that the cover 203 is located inside the housing 201.

[0062] In this embodiment, a frame 204 is fixed around the notch 202 on the inner surface of the housing 201 so that the cover 203 is located inside the housing 201. This not only makes the overall structure of the refrigerator 200 more organized, but also prevents the edges of the cover 203 from being exposed to the outside of the refrigerator 200, thereby preventing dust from accumulating at the edges of the cover 203.

[0063] In one embodiment of the present invention, the periphery of the notch 202 of the housing 201 has a plurality of second fixing holes 210, and the frame 204 has third fixing holes 211 corresponding one-to-one with the second fixing holes 210. The step of fixing the frame 204 around the notch 202 of the housing 201 may include:

[0064] The frame 204 is fixed to the periphery of the notch 202 of the housing 201 by fasteners inserted into the second fixing hole 210 and the third fixing hole 211.

[0065] In this embodiment, the frame 204 is fixed to the periphery of the notch 202 of the housing 201 by fasteners inserted through the second fixing hole 210 and the third fixing hole 211, which facilitates the disassembly and installation of the frame 204. Of course, the frame 204 can also be fixed to the periphery of the notch 202 of the housing 201 by adhesive.

[0066] In one embodiment of the present invention, the frame 204 can be a frame 204 made of plastic.

[0067] In this embodiment, the hardness of the frame material 204 is generally greater than that of the covering material 203. The frame 204 is made of plastic, which is less prone to deformation and provides a better seal, preventing material spillage. Of course, the frame 204 can also be made of other materials with a hardness greater than that of the covering material 203.
