Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of household appliances, and in particular to a refrigeration appliance. Background Art

[0002] Traditional refrigeration appliances, such as refrigerators or freezers, are the most common refrigeration appliances in modern households. Their multi-door design meets people's diverse needs for storage space and ease of use. Taking refrigerators as an example, there are several main forms of door structure design, especially the structure of door handles, for double-door refrigerators and multi-door refrigerators.

[0003] First, it is common to use a separate plastic, aluminum alloy or polyvinyl chloride (PVC) extruded material to make the handle parts, which need to be assembled on the door body one by one. When the cross-sections of the handle area and the non-handle area are different, this design requires multiple parts to be connected, which undoubtedly increases the material cost and production process, making the entire structure more complicated.

[0004] Secondly, in order to pursue a high volume ratio and ultra-thin door design for refrigerators, some refrigerators use bent door shells and handles (usually made of aluminum alloy or plastic) and assemble them together through multiple connectors. Although this method can achieve an ultra-thin door design, it is not ideal in practical applications due to the complexity and high cost of the components.

[0005] Third, another solution is to use a full-length handle structure formed by bending the door shell as a whole. This solution can effectively reduce the number of components, but the upper and lower ends of the door shell are only partially flanged to cooperate with the upper and lower door edge clips of the door, and the door edge clips are also required to cover the door shell structure, which not only affects the user's perceived quality, but also the overall strength of the door shell is poor and prone to deformation, which in turn affects the heat preservation and refrigeration performance of the refrigerator.

[0006] In summary, although the existing refrigerator door design technology has met the requirements of ultra-thinness and high volume ratio to a certain extent, there are still many defects in the structure of the door handle and the strength of the door shell, such as high material cost, complex production process, poor user-perceived quality, and easy deformation of the door body. These are the technical problems that need to be solved in the future refrigerator door design. Utility Model Content

[0007] An object of the embodiments of the present utility model is to provide an improved refrigeration appliance.

[0009] Therefore, by adopting the full flange structure and the door side card, the strength of the whole door body is significantly improved, the deformation of the door body can be better solved, and the user experience is improved. Furthermore, the aesthetics and practicality of refrigerators or freezers and other refrigeration appliances are also improved, so that the refrigeration appliances can meet the design requirements of modern families for large capacity and high volume ratio while taking into account the performance and user experience of the product.

[0010] Optionally, in a plane perpendicular to the height direction of the door, the door edge clip does not exceed the area enclosed by the door shell. This helps to improve the aesthetics of the door and enhance the user experience. Furthermore, when this solution is applied to a double-door or multi-door refrigerator, it also helps to avoid interference between the doors when they are opened and closed.

[0011] Optionally, the door edge card is provided with a receiving groove, which is open toward the first side to receive the flange. Thus, it can be ensured that the door edge card will not protrude from the door shell after the door edge card and the door shell are assembled. Furthermore, through the cooperation of the flange and the receiving groove, the cooperation between the door edge card and the door shell can be made more secure and tight.

[0012] Optionally, the flange is bent and formed before the handle groove. Thus, during the manufacturing process, the mold is bent and formed before the handle groove is shaped, so as to obtain a full flange structure on the second wall integrated with the handle groove.

[0013] Optionally, the flange includes a first flange formed by bending from the edge of the handle groove, and the first flange extends continuously along the shape of the handle groove. Thus, the first flange of the entire handle groove is a continuous complete flange, which is beneficial to improving the structural strength of the handle groove area.

[0014] Optionally, the second wall includes a third wall, the handle groove is located between the first wall and the third wall, the third wall is used to form the side surface of the door, and the flange includes a second flange formed by bending from the edge of the third wall, and the second flange seamlessly connects with the first flange. Therefore, the connection between the third wall and the handle groove belongs to the front of the door, that is, it is visible to the user, and the continuous flange is conducive to reducing the sense of fragmentation on the front of the door and improving the appearance of the refrigeration appliance.

[0015] Optionally, a first notch is provided at the connection between the first flange and the second flange on a side away from the edge, and the first notch is used to make the first flange and the second flange avoid each other when the handle groove is bent and formed. Thus, under the premise that the first flange and the second flange are not separated, the two flanges are prevented from interfering with each other when the handle groove is bent and formed, making the manufacturing process smoother and ensuring that the processed flange is flat without obvious wrinkle areas to avoid affecting the subsequent assembly with the door edge card.

[0016] Optionally, the chamfer radius of the connection between the handle groove and the third wall is not less than 4 mm. Thus, the requirements of the molding process can be met without disconnecting the flange during the manufacturing process.

[0017] Optionally, the second wall includes a fourth wall, which is located between the first wall and the handle groove, the fourth wall is used to form the side surface of the door, the flange includes a third flange formed by bending from the edge of the fourth wall, and the first flange and the third flange are discontinuous. Thus, the discontinuous flange makes the chamfer of the bend at the connection between the fourth wall and the wall forming the handle groove as small as possible, so as to minimize the thickness of the door body and improve the volume ratio of the refrigerator. Furthermore, the discontinuous flange is set at the non-exterior surface of the door, that is, the surface that is invisible to the user when the door is closed, thereby ensuring the aesthetic appearance of the refrigerator.

[0018] Optionally, the chamfer radius of the connection between the fourth wall and the handle groove is 1 to 1.5 mm. Thus, the thickness of the door body can be reduced to the maximum extent, an ultra-thin door body can be achieved, and the volume ratio of the refrigerator can be improved.

[0019] Optionally, the edge of the first wall close to the second side is bent to form a front flange, and the front flange is seamlessly connected to the flange. Therefore, the connection between the first wall and the second wall also belongs to the front side of the door, that is, it is visible to the user, and the continuous flange is conducive to reducing the sense of separation on the front side of the door and improving the appearance of the refrigerator.

[0020] Optionally, a second notch is provided at the connection between the flange and the front flange on a side away from the edge, and the second notch is used to make the flange and the front flange avoid each other when the handle groove is bent and formed. Thus, under the premise that the flange and the front flange are not separated, the two flanges are prevented from interfering with each other when the handle groove is bent and formed, ensuring that the processed flange and the front flange have a smooth transition, and there is no obvious wrinkle area at the connection between the two to avoid affecting the subsequent assembly with the door edge card.

[0021] Optionally, the chamfer radius of the connection between the first wall and the second wall is not less than 4 mm. Thus, the requirements of the molding process can be met without disconnecting the flange and the front flange during the manufacturing process.

[0022] Optionally, the edge of the second wall away from the first wall is bent toward the inside of the door to form a fifth wall, and the door further includes a door liner, the door liner overlaps the fifth wall, and the edge of the fifth wall away from the second wall is bent toward the inside of the door to form a side flange. As a result, the wall that matches the door shell and the door liner is not a complete plane, but an L-shaped structure with a bent end, which can improve the structural strength of the door shell. Specifically, when performing the foaming process of the door body, it is necessary to place the first wall of the door body downward and place a heavy object on the door liner to avoid deformation of the door body caused by expansion of the foaming agent. The bending design of the fifth wall can support the fifth wall to prevent deformation of the door shell and the door liner due to external force.

[0023] Optionally, the door edge card is provided with a receiving cavity open toward the first side, and the fifth wall and the side flange are accommodated in the receiving cavity. Thus, the fifth wall and the side flange are hidden in the receiving cavity and cannot be seen from the outside, which is beneficial to improving the aesthetics of the door appearance and enhancing the user experience.

DETAILED DESCRIPTION

[0034] As mentioned in the background technology, the door shell of the existing refrigeration appliance only cooperates with the door edge clip of the door through partial flanges at the two ends of the handle groove, and the door edge clip needs to be used to cover the door shell structure. This not only affects the user's perceived quality, but also the overall strength of the door shell is poor and prone to deformation, which in turn affects the heat preservation and refrigeration performance of the refrigerator.

[0035] To solve the above technical problems, an embodiment of the utility model provides a refrigeration appliance, comprising: a box body and a door, the box body defines at least one storage chamber, the door is movably connected to the box body to open or close at least a part of the storage chamber, the door comprises: a door shell, the door shell comprises: a first wall for forming a front surface of the door, the first wall having a first side and a second side adjacent to each other; a second wall, bent backward from the first side, the second wall is bent to form a handle groove at least connected to the second side, the edge of the second wall close to the second side is bent to form a flange, and the flange extends basically continuously along the bending shape of the second wall; the door also comprises: a door edge card, connected to the second side in cooperation with the flange.

[0036] Therefore, by adopting the full flange structure and the door side card, the strength of the whole door body is significantly improved, which can better avoid the problem of door body deformation, making it smoother for users to open and close the door, and improving the user experience. Furthermore, it also improves the aesthetics and practicality of refrigerators or freezers and other refrigeration appliances, so that refrigeration appliances can meet the design needs of modern families for large capacity and high volume ratio, while taking into account product performance and user experience.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0038] Figure 1 It is a schematic diagram of a refrigeration appliance 100 according to an embodiment of the present utility model.

[0039] refer to Figure 1 The refrigeration appliance 100 may be, for example, a refrigerator, a freezer, etc. Figure 1 A side-by-side refrigerator is used as an example for demonstration. In practical applications, the design of the door and door handle structure of this embodiment can also be applied to various forms of refrigeration appliances such as multi-door refrigerators and single-door refrigerators. In practical applications, the design of the door and door handle structure of this embodiment can be applied to hinged doors and drawer-type doors.

[0040] For ease of description, in this embodiment, the width direction of the refrigeration appliance 100 is recorded as the x direction, the depth direction is recorded as the y direction, and the height direction is recorded as the z direction. In this embodiment, the front-to-back direction refers to the y direction and the opposite direction when the door 102 closes the storage chamber 103, wherein the front or front side refers to the direction facing the user when the refrigeration appliance 100 is in use, and the rear or rear side refers to the direction away from the user when the refrigeration appliance 100 is in use. In this embodiment, the up-down direction refers to the z direction and the opposite direction.

[0041] Specifically, the refrigeration appliance 100 described in the embodiment of the utility model includes a box body 101 and a door 102 , the box body 101 defines at least one storage chamber 103 , and the door 102 is movably connected to the box body 101 to open or close at least a portion of the storage chamber 103 .

[0042] In some embodiments, the refrigeration appliance 100 may be, for example, a double-door or multi-door refrigerator, that is, there are two doors 102. Further, there may be multiple storage chambers 103, which may provide refrigeration spaces for storing different items, such as a refrigerator and a freezer.

[0043] Further, combined with Figure 1 and Figure 3The door 102 may include a door shell 1, a door liner 5, and a door edge card 2. The door shell 1 and the door liner 5 are connected together through the door edge card 2 to form the whole of the door 102.

[0044] In some embodiments, the door shell 1, the door liner 5 and the door edge card 2 together enclose a heat-insulating space 10 (such as Figure 7 and Figure 8 As shown). The heat-insulating material may be, for example, a foaming agent. Thus, the foaming agent can bond the door shell 1, the door liner 5 and the door edge card 2, so that the overall structural strength of the door 102 is further improved. When the door 102 closes the storage room 103, the heat-insulating layer formed by the heat-insulating space 10 can play a role in isolating heat, so as to ensure that the storage room 103 has a better refrigeration / freezing effect, further improve the cold-keeping effect of the refrigeration appliance 100, and reduce energy consumption.

[0045] The door shell 1 is suitable for forming the front surface of the door 102 (that is, the exterior surface of the refrigeration appliance 100) and a pair of opposite side surfaces. The door liner 5 faces the cabinet 101 when the door 102 is closed, and the door edge card 2 is at least arranged on two opposite sides of the door 102. The heat-insulating space 10 is located between the door liner 5 and the door shell 1. The door liner 5 is also called the inner liner and is suitable for forming the rear surface of the door 102. In some embodiments, the door shell 1 forms at least a part of the front boundary of the heat-insulating space 10 so that the insulation material contacts the rear side of the door shell 1. The door 102 in this example may be a steel plate door. In other embodiments, a front panel may be provided on the front side of the door shell 1. The front panel may be a glass plate or a ceramic plate. The door 102 in this example may be a glass door.

[0046] Further, the door shell 1 may include: a first wall 11, used to form the front surface of the door 102, the first wall 11 having a first side 111 and a second side 112 adjacent to each other; a second wall 12, formed by bending the first side 111 backward (for example, in the opposite direction of the y direction), the second wall 12 being bent to form a handle groove 13 at least connected to the second side 112, the edge of the second wall 12 close to the second side 112 being bent to form a flange 14, the flange 14 extending substantially and continuously along the bending shape of the second wall 12. Further, the door edge card 2 is connected to the second side 112 in cooperation with the flange 14.

[0047] Bending backward refers to bending in a direction away from the front surface of the door 102 . When the door 102 closes at least a portion of the storage chamber 103 , it is bent toward the box body 101 .

[0048] Specifically, refer to Figure 1 and Figure 3 The first wall 11 may be, for example, a wall of the door shell 1 facing the y direction, that is, an appearance surface of the refrigeration appliance 100 .

[0049] In some embodiments, a whole tempered glass panel may be attached to the first wall 11 to enhance the overall aesthetics of the door 102 and also to improve the durability of the first wall 11 .

[0050] Furthermore, the first wall 11 has a first side 111 and a second side 112 adjacent to each other, wherein the first side 111 may be, for example, a side facing the x-direction, and the second side 112 may be, for example, a side facing the z-direction.

[0051] refer to Figure 1 and Figure 3 The first side 111 and the other side opposite to the first wall 11 along the x direction are bent backward to form the second wall 12 and the sixth wall 17, respectively. The second wall 12 is suitable for forming the handle groove 13, and the sixth wall 17 is suitable for forming the side surface of the door 102. Further, the sixth wall 17 is close to the hinge side of the door 102, and the corresponding side where the second wall 12 is located can be regarded as the door opening side, and the second wall 12 is integrally formed with the handle groove 13.

[0052] In some embodiments, the sixth wall 17, the first wall 11, and the second wall 12 can be made of the same plate material, in other words, the two are integrally formed. For example, in the manufacturing stage, the flat door shell 1 is first trimmed, and then the edge of the flat door shell 1 is bent multiple times to form the flange 14, the front flange 15, the side flange 16, the side surface of the door 102 (such as the second wall 12 and the sixth wall 17), and the wall that matches the door liner 5 (such as the fifth wall 123). Then, the second wall 12 is folded into a U-shape to form the handle groove 13.

[0053] Furthermore, side clips 2 are respectively provided on two opposite sides of the door shell 1 along the z direction, so that the door shell 1 , the door liner 5 and a pair of door side clips 2 together enclose a heat-insulating space 10 .

[0054] In some embodiments, the handle groove 13 is formed by bending the second wall 12. Figure 4 , Figure 7 and Figure 8 The handle groove 13 may include a front wall 132 and a rear wall 133 spaced apart along the depth direction (i.e., the x direction) of the door 102, and a bottom wall 134 located between the front wall 132 and the rear wall 133. Further, the front wall 132, the first wall 11, and the fourth wall 122 located therebetween together form a gripping portion 131, and a user's hand may be inserted into the handle groove 13 and then grasp the gripping portion 131, thereby conveniently operating the door 102 to open or close the storage chamber 103.

[0055] Furthermore, the gripping portion 131 is formed by the first wall 11 and the second wall 12. Also, from the user's perspective, the portion of the first wall 11 close to the first side 111 constitutes the surface of the gripping portion 131 facing the user, and the front surface of the door 102 (the surface facing the y direction) always remains flat and smooth, which is beneficial to improving the aesthetic appearance and enhancing the user experience.

[0056] Furthermore, the handle groove 13 is at least connected to the second side 112 .

[0057] In some embodiments, along the z direction, the handle groove 13 connects the second side 112 and the third side 113 opposite to the second side 112. In other words, along the extension direction of the handle groove 13 (eg, z direction), the entire second wall 12 is bent to form a through-length handle groove 13.

[0058] In other embodiments, along the z direction, the second wall 12 can be divided into two parts, one part is bent to form the handle groove 13, and the other part can form the side surface of the door 102 (similar to the sixth wall 17).

[0059] In an application scenario where there are multiple doors 102 , the position of the handle groove 13 may vary according to the specific design.

[0060] by Figure 1 Taking the double-door refrigerator shown as an example, the left and right doors 102 are usually opened and closed relatively. In this scenario, along the x direction, the handle groove 13 can be arranged on the left side of the (right) door 102 or the right side of the (left) door 102. In addition, the extension direction of the handle groove 13 is parallel to the height direction of the refrigeration appliance 100, that is, the z direction.

[0061] In a variation, the two doors 102 may also be arranged up and down along the z direction. In this scenario, the handle groove 13 may be provided on the lower side of the (upper side) door 102 or the upper side of the (lower side) door 102. At this time, the extension direction of the handle groove 13 is parallel to the width direction of the refrigeration appliance 100, that is, the x direction.

[0062] Further, refer to Figure 4 The edge of the second wall 12 close to the second side 112 is bent to form a flange 14 , and the flange 14 extends substantially continuously along the bent shape of the second wall 12 .

[0063] In a preferred embodiment, the flange 14 extends continuously along the bent shape of the second wall 12 to increase the contact area and matching points between the door shell 1 and the door edge card 2, making the connection between the two more secure.

[0064] Basically continuous means that the flange 14 may not be completely continuous, and a small cut may exist due to the limitation of the manufacturing process.

[0065] Furthermore, the door edge card 2 cooperates with the flange 14 to be connected to the second side 112 .

[0066] As described above, by adopting a full flange structure (making the flange 14 extend substantially and continuously along the bending shape of the second wall 12) in cooperation with the door edge clip 2, the strength of the entire door 102 is significantly improved, and the problem of deformation of the door 102 can be better solved, so that the user can open and close the door 102 more smoothly, thereby improving the user experience. Furthermore, the aesthetics and practicality of the refrigerator or freezer 100 are also improved, so that the refrigerator 100 can meet the design requirements of modern families for large capacity and high volume ratio, while taking into account the product performance and user experience.

[0067] Further, refer to Figure 2 In a plane perpendicular to the height direction of the door 102 (e.g., the z direction), the door edge clip 2 does not exceed the area surrounded by the door shell 1. This helps to improve the aesthetics of the door 102 and enhance the user experience. In addition, when this solution is applied to a double-door or multi-door refrigerator, it also helps to avoid mutual interference when the doors 102 are opened and closed.

[0068] Further reference Figure 5 and Figure 6 The extended shape of the door edge card 2 on the first side 111 is adapted to the extended shape of the second wall 12, and the door edge card 2 is provided with a receiving groove 21, which is at least open toward the first side 111 to receive the flange 14. Thus, it can be ensured that the door edge card 2 will not extend beyond the door shell 1 after the door edge card 2 and the door shell 1 are assembled. Furthermore, through the cooperation between the flange 14 and the receiving groove 21, the cooperation between the door edge card 2 and the door shell 1 can be made more secure and tight.

[0069] In some embodiments, continue to refer to Figure 4 The first wall 11 is at least bent at an edge close to the second side 112 to form a front flange 15, and the front flange 15 is seamlessly connected to the flange 14. Therefore, the connection between the first wall 11 and the second wall 12 also belongs to the front side of the door 102, that is, it is visible to the user, and the continuous front flange 15 and flange 14 reduce the sense of separation on the front side of the door 102, thereby improving the appearance of the refrigeration appliance 100.

[0070] Further, the receiving groove 21 is open toward the front surface and the side surface of the door 102 in a plane perpendicular to the height direction (eg, z direction) to receive the front flange 15 on the first wall 11 and the flange 14 on the second wall 12 .

[0071] Furthermore, the extended shape of the receiving groove 21 matches or is consistent with the extended shapes of the flange 14 and the front flange 15 to ensure that the flange 14 and the front flange 15 can be smoothly inserted into the receiving groove 21 .

[0072] Furthermore, the flange 14 is bent and formed before the handle groove 13. Therefore, during the manufacturing process, the mold is bent before the grip portion 131 is formed to form the flange 14, so as to obtain a full flange (including the front flange 15 and the flange 14) structure on the second wall 12 integrated with the handle groove 13, which is conducive to reducing the process difficulty of producing the door 102.

[0073] Continue to refer Figure 4 The flange 14 includes a first flange 141 formed by bending from the edge of the handle groove 13, and the first flange 141 extends continuously along the shape of the handle groove 13. Therefore, the first flange 141 of the entire handle groove 13 is a continuous and complete flange, which is conducive to improving the structural strength of the handle groove 13 area.

[0074] In some embodiments, the second wall 12 includes a third wall 121, the handle groove 13 is located between the first wall 11 and the third wall 121, the third wall 121 is used to form the side surface of the door 102, and the flange 14 includes a second flange 142 formed by bending from the edge of the third wall 121, and the second flange 142 seamlessly connects with the first flange 141. In other words, the first flange 141 and the second flange 142 form a complete flange 14.

[0075] Furthermore, the fourth wall 122 is substantially parallel to the third wall 121, and along the x direction, the fourth wall 122 is closer to the inside of the door 102 than the third wall 121. In other words, the connection between the rear wall 133 and the third wall 121 belongs to the front of the door 102, and is visible to the user when the door 102 closes the storage chamber 103.

[0076] Therefore, the connection between the third wall 121 and the handle groove 13 belongs to the front side of the door 102 , that is, it is visible to the user. The continuous flange 14 is helpful to reduce the sense of separation on the front side of the door 102 and improve the appearance of the refrigeration appliance 100 .

[0077] Furthermore, a first notch 3 is provided at the connection between the first flange 141 and the second flange 142 on a side away from the edge, and the first notch 3 is used to make the first flange 141 and the second flange 142 avoid each other when the handle groove 13 is bent and formed. Thus, under the premise that the first flange 141 and the second flange 142 are not separated, the two flanges are prevented from interfering with each other when the handle groove 13 is bent and formed, making the manufacturing process smoother and ensuring that the processed flange 14 is flat without obvious wrinkle areas to avoid affecting the subsequent assembly with the door edge card 2.

[0078] In some embodiments, the chamfer radius of the connection between the handle groove 13 and the third wall 121 is not less than 4 mm. From the perspective of aesthetics, the smaller the chamfer radius of the connection between the handle groove 13 and the third wall 121, the better. However, from the perspective of the molding process, the larger the chamfer, the simpler the process. 4 mm is the minimum chamfer radius that meets the molding process requirements without disconnecting the flange 14. Therefore, by reasonably controlling the size of the chamfer radius, the molding process requirements can be met without disconnecting the flange 14 during the manufacturing process.

[0079] In some embodiments, continue to refer to Figure 4 , the second wall 12 includes a fourth wall 122, which is located between the first wall 11 and the handle groove 13, and the fourth wall 122 is used to form the side surface of the door 102. The flange 14 includes a third flange 143 formed by bending from the edge of the fourth wall 122, and the first flange 141 and the third flange 143 are discontinuous. Therefore, the discontinuous flange 14 makes the chamfer of the bend at the connection between the fourth wall 122 and the wall forming the handle groove 13 as small as possible, so as to minimize the thickness of the door 102 and improve the volume ratio of the refrigerator. Furthermore, the discontinuous flange 14 is set at the non-exterior surface of the door 102, that is, the surface that is invisible to the user when the door 102 closes the box body 101, thereby ensuring the aesthetic appearance of the refrigerator.

[0080] In some embodiments, when manufacturing the door shell 1, the edge of the second wall 12 close to the second side 112 is folded to form a flange 14 extending continuously from the connection between the second wall 12 and the first wall 11 to the entire second wall 12, and then the connection between the fourth wall 122 and the first flange 141 is cut to form a third notch 6, and the third notch 6 is connected to the edge of the second wall 12. After the handle groove 13 is bent and formed, the first flange 141 and the third flange 143 can be infinitely close to each other without interference, so as to visually eliminate the gap between the first flange 141 and the third flange 143 as much as possible.

[0081] Furthermore, since the third flange 143 and the first flange 141 are cut off to form the third notch 6, the radius of the chamfer at the connection between the fourth wall 122 and the front wall 132 can be appropriately reduced, for example, from 1 to 1.5 mm. Thus, the thickness of the door 102 can be reduced to the maximum extent, an ultra-thin door body can be achieved, and the volume ratio of the refrigerator can be improved.

[0082] In some embodiments, continue to refer to Figure 4The connection between the flange 14 and the front flange 15 is provided with a second notch 4 on the side away from the edge, and the second notch 4 is used to make the flange 14 and the front flange 15 avoid each other when the handle groove 13 is bent and formed. Thus, the flange 14 and the front flange 15 are prevented from interfering with each other when the handle groove 13 is bent and formed without disconnecting, ensuring that the flange 14 and the front flange 15 obtained by processing have a smooth transition, and there is no obvious wrinkle area at the connection between the two to avoid affecting the subsequent assembly with the door edge card 2.

[0083] Further, similar to the shape and function of the first notch 3, the chamfer radius of the connection between the first wall 11 and the second wall 12 is not less than 4 mm. Therefore, during the manufacturing process, the flange 14 and the front flange 15 do not need to be disconnected and the molding process requirements can be met. The flange 14 and the front flange 15 are continuous and can also increase the stability of the connection between the door edge card 2 and the door shell 1.

[0084] In some embodiments, reference Figure 4 , Figure 7 and Figure 8 , the edge of the second wall 12 away from the first wall 11 is bent toward the inside of the door 102 to form a fifth wall 123, and the door 102 also includes a door liner 5, and the door liner 5 is overlapped on the fifth wall 123, and the edge of the fifth wall 123 away from the second wall 12 is bent toward the inside of the door 102 to form a side flange 16. In this scenario, the wall that the door shell 1 and the door liner 5 cooperate with is not a complete plane, but an L-shaped structure with a bent end, which improves the structural strength of the door shell 1. Specifically, when performing the foaming process of the door 102, it is necessary to place the first wall 11 of the door 102 downward and place a heavy object on the door liner 5 to prevent the expansion of the foaming agent from causing deformation of the door 102. The bending design of the fifth wall 123 can support the fifth wall 123 to prevent the connection between the door shell 1 and the door liner 5 from being deformed by external force.

[0085] The fifth wall 123 may be parallel to the first wall 11. The side flange 16 may be parallel to the side surface of the door 102.

[0086] In some embodiments, the fifth wall 123 and the side flange 16 may have the flange 14 structure removed at the edge facing the second side 12 to save production costs. Meanwhile, the fifth wall 123 may be easily bent to form the side flange 16 .

[0087] Continue to refer Figures 5 to 7 The door side card 2 is provided with a receiving cavity 22 opened toward the first side 11, and the fifth wall 123 and the side flange 16 are accommodated in the receiving cavity 22. Thus, the fifth wall 123 and the side flange 16 are hidden in the receiving cavity 22 and are not visible to the outside, which is beneficial to improving the appearance of the door 102 and enhancing the user experience.

[0088] Figure 8 yes Figure 1 The above mainly takes the upper side of the door shell 1 along the z direction (i.e., the second side 112) as an example for illustrative description. In order to clearly show the specific structure of the lower side of the door shell 1 along the z direction (i.e., the third side 112), Figure 8 The door edge card 2 connected to the third side 112 is omitted. It should be understood that in this embodiment, the structures and functions of the upper and lower door edge cards 2 can be the same.

[0089] refer to Figure 8 The door liner 5 is bent on one side close to the x direction to form an installation groove 51 for installing the door seal 7. The door seal 7 can seal the gap between the door 102 and the wall of the box body 101 when the door 102 closes the box body 101, so as to improve the cooling effect of the refrigeration appliance 100 and reduce energy consumption.

[0090] In some embodiments, the door seal 7 is further provided with a magnetic attraction portion 71 to allow the door seal 7 to be closely attached to the shell of the box body 101. Further, the door seal 7 may also include a mounting portion 72, which is used to cooperate with the mounting groove 51 to connect the door seal 7 to the door liner 5.

[0091] In some embodiments, one side of the door liner 5 facing the y direction overlaps the fifth wall 123 .

[0092] Furthermore, the edge of the door seal 7 may also overlap the fifth wall 123 .

[0093] Figure 8 For a detailed description of other structures formed on the third side 113 of the door shell 1 (such as the cooperation between the flange 14 of the second wall 12 near the third side 113 and the door edge card 2 connected to the third side 113, etc.), please refer to the above description of Figure 4 The relevant description is not repeated here.
