Technical Field
[0001] This utility model relates to the field of refrigerator technology, and in particular to a refrigerator outer shell structure. Background Technology
[0002] Refrigerators are among the most commonly used household appliances. Currently, most refrigerators on the market use a bolted assembly structure, typically consisting of multiple side panels connected by bolts. This results in very noticeable seams, making existing refrigerators relatively unattractive, especially small household refrigerators. Furthermore, the bolted assembly of the side panels also leads to relatively poor sealing. Therefore, improvements are urgently needed to meet current societal demands for refrigerator exteriors. Utility Model Content
[0003] The purpose of this utility model is to design a refrigerator outer shell structure to overcome the shortcomings of the above-mentioned technology.
[0004] This utility model designs a refrigerator outer shell structure, including a sheet-like U-shaped frame. The U-shaped frame forms a doorway and an opening. A sealing plate is disposed in the opening. The two sides of the sealing plate along its length are respectively spliced and welded to the opposite two sides of the U-shaped frame located inside the opening to close the opening. The straight sides of the U-shaped frame and the sealing plate located at the doorway both form sheet-like door edges extending inward into the doorway. A sheet-like corner edge is disposed between the length-direction sides of every two sheet-like door edges. The end of each sheet-like corner edge is spliced and welded to the length-direction side of each sheet-like door edge. The edge of each corner of the U-shaped frame located at the doorway is spliced and welded to the rear side of each sheet-like corner edge.
[0005] According to the refrigerator outer shell structure described above, each corner of the annular frame is a rounded corner, and each piece of corner is also a rounded structure.
[0006] According to the refrigerator outer shell structure described above, the ends of each sheet-like corner edge extend toward the sheet-like door edge to form a first splicing piece, and the first splicing piece and the sheet-like door edge are stacked on top of each other.
[0007] According to the refrigerator outer shell structure described above, the first composite piece is stacked on the inner side of the sheet-like door edge. According to the refrigerator outer shell structure described above, the two sides of the closed piece extend along its length direction to form a second splicing piece, and the second splicing piece and the opposite sides of the U-shaped frame located in the opening are stacked on each other.
[0008] According to the refrigerator outer shell structure described above, the second composite piece is stacked on the inner side of the side of the U-shaped frame located inside the opening.
[0009] According to the refrigerator outer shell structure described above, each corner of the U-shaped frame forms a height difference between its edge at the doorway and each piece of door edge, so that a notch is formed on each corner of the U-shaped frame facing the doorway. Each piece of door edge has a piece on its rear side that is adapted to the notch and its edge, and the edge of the piece is spliced and welded to the edge of the notch.
[0010] According to the refrigerator outer shell structure described above, a third splicing piece is formed at the end of the sheet body. The third splicing piece located at the U-shaped frame body is stacked on the inner wall of the U-shaped frame body, and the third splicing piece located at the closing piece body is stacked on the inner side of the closing piece body.
[0011] According to the refrigerator outer shell structure described above, the U-shaped frame and the sheet-like door edges at the doorway are formed by stamping and bending a metal plate.
[0012] According to the refrigerator outer shell structure described above, the gaps formed by the splicing of each part are sealed by welding.
[0013] The present invention relates to a refrigerator shell structure, the technical effect of which is that the basic frame is integrally formed by stamping and bending a metal plate, and the sealing plate is sealed by splicing and welding the opening. The two ends of the plate-shaped corner edge are also spliced and welded to the two adjacent plate-shaped door edges. During welding, the splicing gap is sealed, thereby forming an integral refrigerator shell structure through splicing and welding. After being assembled into a refrigerator, the appearance is more beautiful and the sealing performance of the shell is further improved. Attached Figure Description

[0016] 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.
[0017] Example: This embodiment describes a refrigerator outer shell structure, including a U-shaped frame 1 in the form of a sheet 32. The U-shaped frame 1 forms a doorway 11 and an opening 12. A closing sheet 2 is disposed within the opening 12. The two sides of the closing sheet 2 along its length are respectively welded to the opposite sides of the U-shaped frame 1 located within the opening 12 to close the opening 12. Both the U-shaped frame 1 and the closing sheet 2 have sheet-like door edges 13 extending into the doorway 11 along their straight sides. A sheet-like corner edge 3 is disposed between every two sheet-like door edges 13 along their length. The end of each sheet-like corner edge 3 is welded to the side of each sheet-like door edge 13 along its length. Each U-shaped frame 1... Each corner 14 located at the doorway 11 is welded to the rear side of each piece of corner 3, and the gap formed by each splicing is sealed by welding to form an integrated refrigerator shell. The outer wall of the integrated refrigerator shell can be sprayed with a protective layer, which can be a paint layer. The U-shaped frame 1 and each piece of door edge 13 at the doorway 11 are formed by stamping and bending a metal plate, and the angle between the piece of door edge 13 and the piece of U-shaped frame 1 is a right angle. The sealing plate 2 and the piece of door edge 13 at the doorway 11 are also formed by stamping and bending a metal plate, and the angle between the piece of door edge 13 and the sealing plate 2 is also a right angle. The metal plate is generally a stainless steel sheet.
[0018] Preferably, each corner 14 of the annular frame is a rounded corner 14, and each piece-shaped corner 3 is also a rounded structure. The use of rounded corners 14 makes the outer side of the corner 14 of the refrigerator shell a rounded surface, making the outer side of the refrigerator more aesthetically pleasing.
[0019] In this embodiment, the ends of each sheet-like corner edge 3 extend toward the sheet-like door edge 13 to form a first splicing piece 31, and the first splicing piece 31 and the sheet-like door edge 13 are stacked on each other. The first splicing piece 31 is stacked on the inner side of the sheet-like door edge 13. Its structure allows the sheet-like corner edge 14 to be positioned after assembly to prevent it from coming out and causing misalignment of the welding seam, making welding more convenient. After welding and fixing, the sheet-like corner edge 14 is more stably fixed at the corner edge 14.
[0020] In this embodiment, the two sides of the closed piece 2 extend along its length direction to form a second splicing piece 21, and the second splicing piece 21 and the opposite sides of the U-shaped frame 1 located in the opening 12 are stacked on each other. The second splicing piece 21 is stacked on the inner side of the side of the U-shaped frame 1 located in the opening 12. Its structure allows the closed piece 2 to be positioned after assembly at the opening 12 to prevent it from coming out and causing misalignment of the welding seam, making welding more convenient. After welding and fixing, the closed piece 2 is more stably fixed in the opening 12.
[0021] In this embodiment, each corner 14 of the U-shaped frame 1 has a height difference between its edge at the doorway 11 and each piece of door edge 13, so that a notch 111 is formed on the side of each corner 14 of the U-shaped frame 1 facing the doorway 11. Each piece of door edge 3 has a piece 32 on its rear side that is adapted to the notch 111 and its edge. The edge of the piece 32 is spliced and welded to the edge of the notch 111. The gap formed by splicing is sealed by welding. This structural design makes it easier to weld and fix the corner 14 of the U-shaped frame 1 and the piece of door edge, and also easier to adapt. The piece 32 is also an arc structure.
[0022] Preferably, a third splicing piece 33 is formed at the end of the sheet body 32. The third splicing piece 33 located at the U-shaped frame 1 is stacked on the inner wall of the U-shaped frame 1, and the third splicing piece 33 located at the closing piece 2 is stacked on the inner side of the closing piece 2. The structure allows the sheet body 32 to be positioned after assembly at the notch 111 to prevent it from coming out and causing misalignment of the welding seam, making welding more convenient. After welding and fixing, the closing piece 2 is more stably fixed at the opening 12.
[0023] 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.
