Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, and in particular to a refrigerator shell structure. Background Technology

[0002] Refrigerators are among the most commonly used household appliances, primarily used for refrigerating and freezing food and fruits to prevent spoilage from exposure to room temperature and extend the shelf life of food and fruits. Currently, in refrigerators on the market, the outer and inner shells are assembled, resulting in a height difference between the door edges of the inner and outer shells. This makes the edge where the refrigerator door contacts the sealing ring narrower, forcing the sealing ring on the refrigerator door to also be narrower. The smaller sealing contact area reduces the airtightness between the refrigerator door and the door edge, and the height difference also makes the refrigerator door less aesthetically pleasing. Utility Model Content

The inner edge of the first door edge piece is adapted to the shape of the outer edge of the second door edge piece and they are joined together, and the outer surface of the first door edge piece is flush with the outer surface of the second door edge piece.

[0005] According to the refrigerator shell structure described above, the second door edge extends toward the rear side of the first receiving cavity to form a continuous or spaced insert, and the inner edge of the first door edge extends toward the rear side of the first receiving cavity to form a continuous or spaced connector, and the insert is inserted into the corresponding slot on the connector.

[0006] According to the refrigerator shell structure described above, the insert abuts against an inner wall of the slot near the outer shell, or the insert abuts against another inner wall of the slot near the inner shell.

[0007] According to the refrigerator shell structure described above, the connecting body includes a first side panel, a second side panel, and a closed side. The first side panel and the second side panel are spaced apart from each other, and the closed side is located between the two. One end of the first side panel is connected to the inner edge of the first door edge piece, and the opposite sides of the closed side are respectively connected to the other end of the first side panel and the other end of the second side panel, so that the three of them form a slot.

[0008] According to the refrigerator shell structure described above, one end of the second side panel is positioned close to the inner side of the second door edge to form a cavity between them. The cavity is filled with a soft layer, and the front and rear sides of the soft layer respectively abut against one end of the second side panel and the inner side of the second door edge.

[0009] According to the refrigerator shell structure described above, one end of the second side panel extends toward the inner shell to form a baffle, and the outer wall of the baffle abuts against the rear side of the soft layer.

[0020] 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.

[0021] Example 1: The refrigerator shell structure described in this embodiment includes an outer shell 4 and an inner shell 5; wherein both the outer shell 4 and the inner shell 5 are made of thin metal sheets, and the inner shell 5 is integrally stamped from the thin metal sheet.

[0022] The outer shell 4 is provided with a first receiving cavity 41 and a front opening located on the front side of the first receiving cavity 41. The outer edge of the front opening extends inward to form a first door edge piece 42. The outer edge of the front opening of the first door edge piece 42 is continuously arranged so that the inner edge of the first door edge piece 42 defines a first inner opening 48 located within the range of the front opening. The first door edge piece 42 is annular and is integrated with the outer shell 4 to form an integral structure.

[0023] The inner shell 5 is placed in the first receiving cavity 41 through the first inner opening 48. The inner shell 5 is provided with a second receiving cavity 51 and a second inner opening 52 located in front of the second receiving cavity 51. The outer edge of the second inner opening 52 extends towards the outer edge of the front opening to form a second door edge piece 53. The second door edge piece 53 is continuously arranged along the outer edge of the second inner opening 52. The second door edge piece 53 is annular and is integrated with the inner shell 5 to form an integral structure.

[0024] A cavity 6 is formed between the inner wall of the first receiving cavity 41 and the outer wall of the outer shell 4. The cavity 6 is filled with an adhesive material to connect the outer shell 4 and the inner shell 5 and fix them together. The adhesive material is generally expanding foam. The inner edge of the first door edge piece 42 and the outer edge of the second door edge piece 53 are adapted to each other and fit together. The outer side of the first door edge piece 42 and the outer side of the second door edge piece 53 are flush. Therefore, the edge of the refrigerator door is wider, which increases the sealing contact surface. This allows the width of the sealing ring on the refrigerator door to be increased, thereby improving the sealing performance between the refrigerator door and the edge of the refrigerator door after sealing with the sealing ring. The flush setting also makes the edge of the refrigerator door more aesthetically pleasing.

[0025] Preferably, in order to make the refrigerator shell more aesthetically pleasing, the corners of the outer shell 4 or the inner shell 5 are rounded.

[0026] In this embodiment, the second door edge piece 53 extends toward the rear side of the first receiving cavity 41 with continuously or spaced insert pieces 54, and the inner edge of the first door edge piece 42 extends toward the rear side of the first receiving cavity 41 with continuously or spaced connecting bodies. The insert pieces 54 are inserted into the corresponding slots 46 on the connecting bodies. The structure is designed so that the inner edge of the first door edge piece 42 and the outer edge of the second door edge piece 53 are adapted to each other and can be positioned to avoid misalignment due to moving the assembled refrigerator shell before applying expanding foam.

[0027] In this embodiment, the insert 54 abuts against an inner wall of the slot 46 near the outer shell 4, or the insert 54 abuts against another inner wall of the slot 46 near the inner shell 5. The insert 54 abuts against the inner wall of the slot 46, so that frictional resistance is formed between the insert 54 and the inner wall of the slot 46, making it difficult for the insert 54 to fall out of the slot 46. As a result, the inner shell 5 is more reliably positioned on the outer shell 4, making the structure more compact.

[0028] In this embodiment, the connector includes a first side stop 43, a second side stop 44, and a closed side 45. The first side stop 43 and the second side stop 44 are spaced apart from each other, and the closed side 45 is located between them. One end of the first side stop 43 is connected to the inner edge of the first door edge piece 42. The opposite sides of the closed side 45 are respectively connected to the other end of the first side stop 43 and the other end of the second side stop 44, so that the three form a slot 46. The second door edge piece 53, the first side stop 43, the second side stop 44, and the closed side 45 are combined into an integral structure.

[0029] Furthermore, the inner edge of the first door edge piece 42 is connected to one end of the first side block 43 through an arc transition, and the outer edge of the second door edge piece 53 is connected to the insert piece 54 through an arc transition. When the inner edge of the first door edge piece 42 and the outer edge of the second door edge piece 53 are joined together, their arc transition structures abut against each other, making the inner edge of the first door edge piece 42 and the outer edge of the second door edge piece 53 fit together more tightly, thus improving the compactness of the structure.

[0030] Preferably, one end of the second side guard 44 is positioned close to the inner surface of the second door edge piece 53 to form a cavity 7 between them. The cavity 7 is filled with a soft layer, and the front and rear sides of the soft layer respectively abut against one end of the second side guard 44 and the inner surface of the second door edge piece 53. The flexible layer 8 is made of sponge or soft rubber. Its structure enables flexible buffering and isolation between one end of the second side guard 44 and the inner surface of the second door edge piece 53, which has the effect of shock absorption and noise reduction.

[0031] Preferably, one end of the second side baffle 44 extends toward the inner shell 5 to form a baffle 47, the outer wall of the baffle 47 abuts against the rear side of the soft layer, wherein the baffle 47 is formed by bending a thin sheet at one end of the second side baffle 44.

[0032] In this embodiment, a partition 511 is provided in the second receiving cavity 51 so that at least two chambers 512 are formed in the second receiving cavity 51 by partitioning through the partition 511.

[0033] Example 2: The refrigerator shell structure described in this embodiment is the same as that in Embodiment 1, but the difference is that the shell includes 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 sealing sheet 2 is disposed in the opening 12. The two sides of the sealing sheet 2 in the longitudinal direction are respectively spliced ​​and welded to the opposite sides of the U-shaped frame 1 located in the opening 12 to close the opening 12. The straight sides of the U-shaped frame 1 and the sealing sheet 2 located in the doorway 11 are both formed into sheet-like door edges 13 extending into the doorway 11. A sheet-like corner edge 3 is disposed between every two sides of the sheet-like door edges 13 in the longitudinal direction. The end of each sheet-like corner edge 3 is spliced ​​and welded to the side of each sheet-like door edge 13 in the longitudinal direction. Each corner 14 of the U-shaped frame 1 is welded to the rear side of each piece of corner edge 3 at the doorway 11, 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 piece of door edge 13 of the U-shaped frame 1 and its doorway 11 is 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 piece of door edge 13 of the sealing plate 2 and its doorway 11 is 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.

[0034] Preferably, each corner 14 of the U-shaped frame 1 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 corners 14 of the refrigerator shell a rounded surface, making the outer side of the refrigerator more aesthetically pleasing.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.
