[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0018] Example: This embodiment describes a refrigerator compressor 4 mounting structure, including a back plate 2, a cover 3, and an outer shell 1. The outer shell 1 has a rear opening 10, and the back plate 2 is installed on the rear opening 10 to partially close it, so that the unclosed part of the rear opening 10 forms a mounting port 11 for the compressor 4 to enter the inner cavity of the outer shell 1. The cover 3 is located in the inner cavity of the outer shell 1 corresponding to the position of the mounting port 11. The edge of the front opening of the cover 3 is connected and fixed to the mounting port 11. Side wings 331 are provided on opposite sides of the mounting port 11 on the cover 3, and the edges of the side wings 331 are connected to the edges of the mounting port 11. A mounting cavity 30 for mounting the compressor 4 is formed inside the cover 3. The inner shell 6 is provided in the inner cavity of the outer shell 1. The door edge 15 of the front opening edge of the inner shell 6 is spliced ​​and connected with the door edge 15 of the front opening edge of the outer shell 1. A part of the edge of the rear opening 10 and a part of the edge of the mounting port 11 are formed into U-shaped bodies 13. The edges of the back plate 2 and the side wing 331 extend to form plug-in pieces 22. The plug-in pieces 22 are inserted into the plug-in groove 131 of the U-shaped body 13. The inner wall of the outer shell 1, the inner wall of the back plate 2, the inner wall of the side wing 331 and the outer wall of the cover 3 are all filled with foam glue between them and the outer wall of the inner shell 6 so that the outer shell 1, the back plate 2, the side wing 331 and the cover 3 are connected to each other. This structure makes the installation of the back plate 2 convenient. The U-shaped body 13 is formed by stamping and bending the sheet of the rear opening 10 edge of the outer shell 1.

[0019] Preferably, an elastic layer 8 is provided between the inner wall of the back plate 2 and the side wing 331 and the end of the U-shaped body 13, or an elastic layer 8 is provided between the inner wall of the back plate 2 and the side wing 331 and the pad 132 at the end of the U-shaped body 13. The elastic layer 8 can be a sponge. Its structure allows the back plate 2 and the side wing 331 to achieve flexible buffer isolation with the U-shaped body 13, which has the effect of shock absorption and noise reduction.

[0020] Furthermore, the door edge 15 of the front opening edge of the inner shell 6 is formed with a insert 62, and the door edge 15 of the front opening edge of the outer shell 1 is formed with a U-shaped piece 16. The insert 62 is inserted into the slot 161 of the U-shaped piece 16 for positioning, and the abutting piece 162 at the end of the U-shaped piece 16 is flexibly isolated from the front opening edge of the inner shell 6 by a flexible layer 18, thereby achieving the effect of shock absorption and noise reduction.

[0021] In this embodiment, the cover 3 includes two side plates 33 and an L-shaped cover 32. The end of the transverse piece 321 of the cover 32 is connected to the upper side of the mounting port 11, and the end of the longitudinal piece 322 of the cover 32 is in contact with or connected to the bottom of the inner cavity of the outer shell 1, so that a cavity is formed between the mounting port 11 and the longitudinal piece 322 of the cover 32, and side openings are located at opposite ends in the width direction of the cavity. The two side plates 33 are respectively installed on each side opening to close them, thereby forming a mounting cavity 30. Each side wing 331 is respectively formed on the two side plates 33. Its structural configuration makes the cover 3 also a split structure, realizing a smaller manufacturing equipment used to manufacture the cover 3, thereby reducing manufacturing costs and manufacturing complexity.

[0022] Preferably, each of the side plates 33 has a baffle 333 extending toward the cover 32 on its side edge opposite to the edge of the cover 32. The baffle 333 is in close contact with the outer wall of the outer shell 1. The longitudinal piece 322 or the transverse piece 321 of the cover 32 has an extension piece 325 extending from both ends of its width direction. The baffle 333 or the side plate 33 has a through hole 335 corresponding to the position of the extension piece 325. The extension piece 325 passes through the through hole 335 and then bends. This structure makes it easier to install and fix the side plate 33 on the cover 32, and the structure design is reasonable.

[0023] In this embodiment, a support portion 21 is formed on the edge of the back plate 2 at the cavity opening 31 of the mounting cavity 30. The end of the transverse piece 321 of the cover 32 is supported by the support portion 21, and a third connecting piece 324 extends from the end of the longitudinal piece 322 of the cover 32. The third connecting piece 324 is attached to the bottom inner wall of the outer shell 1. It is designed to be pre-positioned during the assembly of the cover 32. Therefore, after the cover 32 is positioned, a first connecting piece 323 extends from the end of the transverse piece 321 and the upper end of the side wing 331 of the cover 32. Each first connecting piece 323 is attached to the support portion 21. The inner wall of the back plate 2 above the mounting opening 11 is covered by the first pressure strip 7, which is pressed against the inner wall of each of the first connecting pieces 323. The mounting cavity 30 is covered by a cover plate 9 at the cavity opening 31 on one side of the mounting opening 11. A first fastener is passed through the cover plate 9. The first fastener passes through the back plate 2 and the first connecting piece 323 and is fixedly connected to the first pressure strip 7, so that the cover plate 9, the first connecting piece 323 and the first pressure strip 7 are fixed on the back plate 2, and each of the first connecting pieces 323 is clamped and fixed between the back plate 2 and the first pressure strip 7. Therefore, the above structure makes it easier to fix the cover 32 on the back plate 2.

[0024] Preferably, the cover plate 9 is provided with vent holes so that the heat generated by the compressor 4 can be released through the vent holes.

[0025] In this embodiment, each side plate 33 has a second connecting piece extending from its bottom edge. Each second connecting piece is attached to the bottom inner wall of the outer shell 1. A second pressure strip 17 is pressed onto each second connecting piece. A bottom opening 12 is formed below the mounting cavity 30. A bottom plate 5 is provided at the bottom opening 12. Second fasteners are respectively passed through the opposite ends of the bottom plate 5. After passing through the outer shell 1 and the bottom plate, the second fasteners are fixedly connected to the second pressure strip 17 to fix the second pressure strip 17, the bottom plate, and the bottom plate 5 on the outer shell 1. The second connecting piece is clamped and fixed between the bottom inner wall of the outer shell 1 and the second pressure strip 17. The structural design combined with the installation method of the second pressure strip 17 makes the installation of the cover 3 on the outer shell 1 and the back plate 2 more stable and reliable, and improves the compactness of the structure.

[0026] Finally, a mounting hole 332 is provided on one side panel 33, and a power controller 14 is embedded in the mounting hole 332. The power cord of the power controller 14 passes through the through hole of the cover plate 9 and then comes out. Multiple sockets are also provided on the back panel 2 so that the contacts of the power plug on the power cord can be inserted into each socket to position the plug.

[0027] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
