[0040] like Figure 1 and Figure 2 As shown, the refrigerator metal door shell 3 according to the first aspect of the present invention includes a door shell body 31 and a plurality of thickened portions 32. The door shell body 31 has an inner side surface 311. The plurality of thickened portions 32 are all disposed on the inner side surface 311 of the door shell body 31, and the plurality of thickened portions 32 are arranged around the periphery of the door shell body 31. The plurality of thickened portions 32 protrude from the inner side surface 311 at the same height.
[0041] Understandably, the door shell body 31 is used to install the front panel of the refrigerator door. The front panel of the refrigerator door can be a metal panel or a glass panel. Since metal panels are strong enough, they are usually thinner, while glass panels are thicker. Therefore, the production molds for metal panel refrigerator doors and glass panel refrigerator doors cannot usually be shared. To address this, the refrigerator metal door shell 3 of this embodiment aims to solve the problem of material compatibility between refrigerator glass doors and metal doors. By optimizing the structure of the metal panel, the metal panel can be produced entirely using the molds for the glass door.
[0042] According to an embodiment of this utility model, the refrigerator metal door shell 3 has multiple thickened portions 32 provided on the inner side 311 of the door shell body 31. These thickened portions 32 have the same thickness, resulting in a smooth surface during refrigerator door assembly. The thickened portions 32 are only located around the periphery of the door shell body 31, eliminating the need to cover the entire inner side 311, thus thickening the refrigerator metal door shell 3 and reducing overall weight. By optimizing the structure of the refrigerator metal door shell 3, its thickness is made the same as the glass panel thickness, allowing it to be assembled into a refrigerator door using glass door molds. Specifically, during production, the door shell body 31 is directly foamed by fixing it to the refrigerator door pillars 2 and end caps 5 via the multiple thickened portions 32 around its periphery, making it perfectly compatible with glass door molds.
[0043] It should be noted that the thickened portion 32 is located on the inner side 311 of the door shell body 31, which is the side facing away from the user, to facilitate installation and connection. The connection method between the door shell body 31 and the thickened portion 32 can be bonding, welding, threaded connection, etc., and is not limited here. In other embodiments, the two can also be an integrally formed structure to improve structural stability.
[0044] like Figures 2 to 4 As shown, according to one embodiment of the present invention, the thickened portion 32 includes a flange 321 and a flattened portion 322. The flange 321 protrudes from one edge of the inner surface 311, and the flattened portion 322 is connected to the flange 321 and extends toward the edge away from the inner surface 311. For example, the flange 321 protrudes perpendicular to the inner surface 311 to achieve a thickening effect. Simultaneously, the flattened portion 322, connected to the flange 321, increases the overall volume of the thickened portion 32, facilitating its connection and installation at the refrigerator door pillar 2, thereby improving connection stability.
[0045] According to one embodiment of the present invention, the folded portion 322 is spaced apart from the inner side surface 311. In this embodiment, the side of the door shell body 31 facing away from the inner side surface 311 is the outer side surface. That is, the thickness of the refrigerator metal door shell 3 is formed between the side of the folded portion 322 facing away from the inner side surface 311 and the outer side surface of the door shell body 31. This thickness is consistent with the thickness of the glass panel, so as to be suitable for the production of the refrigerator door using a glass door mold. By forming a gap between the folded portion 322 and the inner side surface 311, the weight of the folded portion 322 is reduced, thereby reducing production costs. In addition, the gap formed between the folded portion 322 and the inner side surface 311 can also be filled with foam material to improve insulation.
[0046] According to one embodiment of this utility model, the flat fold portion 322 is parallel to the inner surface 311. It is understood that the flat fold portion 322 is used to connect with the upright 2 of the refrigerator door. Having multiple flat fold portions 322 on the same plane improves the flatness of the connection and facilitates connection. It should be noted that parallelism here does not refer to absolute parallelism; certain production and installation errors are allowed. Of course, the inner surface 311 can be a flat surface or a non-flat surface. The flat fold portion 322 is approximately parallel to the inner surface 311 so that multiple flat fold portions 322 are on the same plane. In this way, the thickness of all parts of the refrigerator metal door shell 3 is the same, allowing for complete universal use of glass door molds.
[0047] Of course, in other embodiments, the flat fold 322 may also be arranged non-parallel to the inner surface 311. For example, the inner surface 311 may be a concave arc surface. In this case, it is sufficient to ensure that multiple flat folds 322 are on the same plane.
[0048] According to one embodiment of the present invention, in order to facilitate the production and molding of the refrigerator metal door shell 3, a notch 323 is provided at the connection of two adjacent flat folds 322, and the notch 323 is provided at the corner of the door shell body 31. For example, the door shell body 31 is rectangular, and thickened portions 32 are provided on all four sides of the door shell body 31. A gap is formed between the ends of the flat folds 322 on two adjacent sides to form a notch 323, which facilitates the insertion of external production equipment from the notch 323 between the flat fold 322 and the inner side surface 311. The notch 323 can also be used to clamp the door shell body 31. In this way, the refrigerator metal door shell 3 will not have defects such as unevenness or paint peeling during its molding process.
[0049] Please refer to the reference. Figure 1 and Figure 2According to one embodiment of the present invention, each flat fold 322 has a guide bevel 3221 at one end adjacent to the notch 323. The guide bevel 3221 is inclined towards the flange 321 in the direction close to the notch 323. It can be understood that the guide bevels 3221 of two adjacent flat folds 322 are arranged opposite each other to form a notch 323 that is flared in the corner direction away from the door shell body 31, thereby increasing the notch 323 to avoid obstructing external production equipment. At the same time, the guide bevel 3221 is provided at the end of the flat fold 322 to prevent its end from being too sharp and scratching the external production equipment.
[0050] According to one embodiment of the present invention, the door shell body 31 and a plurality of thickened portions 32 are integrally formed. That is, the plurality of thickened portions 32 are formed by bending inward from the four edges of the door shell body 31, which saves installation steps and facilitates production.
[0051] Please refer to the reference. Figures 3 to 5 According to a second aspect embodiment of the present invention, the refrigerator door includes a door body and the aforementioned refrigerator metal door shell 3. A plurality of thickened portions 32 of the refrigerator metal door shell 3 are connected to the door body and enclose a foaming cavity 4. It is understood that since the thickened portions 32 around the refrigerator metal door shell 3 are connected to the door body, the overall thickness of the refrigerator door using the refrigerator metal door shell 3 is consistent with the overall thickness of the refrigerator door using a glass panel, allowing the use of the same set of production molds and reducing mold investment waste and material differentiation.
[0052] According to one embodiment of the present invention, the door body includes a door core 1 and two uprights 2. One upright 2 is located on one side of the door core 1, and the other upright 2 is located on the other side of the door core 1. Each upright 2 has a connecting portion 21, and a connecting gap is formed between the connecting portion 21 and the thickened portion 32. The connecting gap is used to fill the gap with fixing adhesive 6 to connect the connecting portion 21 and the thickened portion 32. It can be understood that the two uprights 2 help to improve the structural stability of the door body and prevent door deformation. Exemplarily, the upright 2 extends in a direction parallel to the thickened portion 32, and the length of the extension is greater than the distance between the thickened portion 32 and the edge of the door shell body 31, so as to facilitate the connection between the thickened portion 32 and the connecting portion 21. Specifically, the flattened portion 322 of the thickened portion 32 extends parallel to the connecting portion 21 of the upright 2 to form a connecting gap between them, thereby filling the gap with fixing adhesive 6 and improving the connection stability. In one embodiment, the door body also includes an end cap 5. The refrigerator metal door shell 3, the door liner 1, and the end cap 5 are arranged to form a foaming cavity 4. When producing the door, the refrigerator metal door shell 3 can be directly foamed by fixing it to the column 2 and the end cap 5 using VHB tape or glue.
[0053] The refrigerator according to the present utility model embodiment includes the above-mentioned refrigerator metal door shell 3, and therefore has all the technical effects of the above-mentioned refrigerator metal door shell 3, which will not be repeated here.
[0054] According to a third aspect embodiment of the present invention, the refrigerator includes a cabinet and the aforementioned cabinet door, the cabinet door being connected to the cabinet.
[0055] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
