Description

Technical Field

[0001] The embodiments of the present utility model relate to the technical field of refrigeration appliances, and more particularly to a refrigeration appliance. Background Art

[0002] Generally in the current market, for side-by-side refrigerators and multi-door refrigerators, a door body structure with left and right side-opening doors is commonly adopted. A vertical handle structure is provided on the side surfaces of the two doors facing each other to form a door handle. Users operate the door body through the door handle to open or close the storage compartment of the refrigerator.

[0003] In the existing door handle structure design, as long as the cross-sections of the handle area and the non-handle area on the side of the door are different, multiple components are required for connection. This will undoubtedly increase the material cost and production processes, and the assembly complexity is high. Summary of the Utility Model

[0004] An object of the embodiments of the present utility model is to provide an improved refrigeration appliance.

[0005] Therefore, the embodiments of the present utility model provide a refrigeration appliance, including: a box body and a door. The box body defines at least one storage compartment. The door is movably connected to the box body to open or close at least a part of the storage compartment. The door includes: a door shell, including a first wall and a second wall bent backward from one side edge of the first wall. The first wall is used to form the front surface of the door. The second wall includes a discontinuous first part and a second part along the height direction of the door. The first part is bent to form a handle groove, and the second part is used to form the side surface of the door; an end cap, disposed between the first part and the second part to block the opening between the first part and the second part.

[0006] In the prior art, a non-through handle groove is usually obtained by assembling multiple components, which is costly and has complex production processes. In contrast, in this application, the handle groove is disconnected from the remaining part of the door shell on the side where the handle groove is located, and the opening formed by the disconnection is blocked by an end cap, so that different cross-sections of the handle area and the non-handle area on the opening side can be realized on the same bent metal plate, thereby integrally manufacturing a non-through handle groove on the door shell. Thus, the number of components on the door is reduced, and on the basis of achieving the same functions and appearance, the component cost and the pre-assembly labor cost of the door body can be reduced.

[0007] Optionally, in a plane perpendicular to the height direction of the door, the cross-sectional shape of the first part is different from that of the second part. The end cap has opposite first and second sides. The first side cooperates with the first part to isolate the first part and the opening, and the second side cooperates with the second part to isolate the second part and the opening; and / or, the end cap forms the boundary of the handle groove in the height direction. Thus, a single component is used to transition between two different cross-sections for assembly, with fewer components on the door, which is beneficial for cost reduction and efficiency improvement.

[0008] Optionally, the first side is provided with a first groove to receive the edge of the first part facing the opening, and the second side is provided with a second groove to receive the edge of the second part facing the opening. Thus, the connection and cooperation between the end cap and the first part, and between the end cap and the second part both adopt a plug-in design, which is beneficial for better sealing and preventing leakage of foam.

[0009] Optionally, the opening direction of the first groove is parallel to the height direction of the door, and / or, the opening direction of the second groove is parallel to the width direction of the door. Thus, the grooves on both sides face different directions, facilitating assembly.

[0010] Optionally, the first part 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 at least part of the end cap is located between the third wall and the second part and is visible from the outside. Thus, in order to form a handle groove with a different cross-sectional shape and the side surface of the door on a single structure on the side of the door shell, a cut is formed on this structure, and the end cap completely seals the cut and forms a part of the appearance surface of the door. After the user opens the door, no obvious gap can be seen, improving the aesthetic appearance of the refrigerator.

[0011] Optionally, the end cap includes a first surface located between the third wall and the second part. Along the width direction of the door, the third wall, the first surface, and the second part are flush. Thus, there is no obvious concave-convex structure on the door, the lines are smooth, and the appearance is beautiful.

[0012] Optionally, the edge of the first part away from the first wall is bent inward towards the inside of the door to form a fourth wall, and the edge of the second part away from the first wall is bent inward towards the inside of the door to form a fifth wall. At least part of the end cap is located between the fourth wall and the fifth wall and is visible from the outside. Thus, the end cap completely seals the opening formed by cutting the side of the door shell (i.e., the second wall) for locally manufacturing the handle groove, avoiding foam leakage during door body foaming and also being beneficial for improving the overall aesthetic appearance of the door.

[0013] Optionally, the end cap includes a second surface located between the fourth wall and the fifth wall, and the fourth wall, the second surface and the fifth wall are flush; and / or, the door further includes a door liner, and the door liner is respectively lapped on the fourth wall, the second surface and the fifth wall. Thus, there is no obvious concave-convex structure on the door, the lines are smooth, and the appearance is beautiful. Further, the flat surface is conducive to the reliable lapping of the inner liner.

[0014] Optionally, for at least one of the first part and the second part, the part is provided with a limiting part, and the end cap is provided with a matching part, and the matching part is used to cooperate with the limiting part to limit the edge of the part away from the first wall from tilting away from the door. Thus, it ensures that the appearance of the door (especially the side surface) is flat and improves the appearance aesthetics.

[0015] Optionally, the limiting part includes a flanging formed by bending the edge of the part towards the inside of the door, the flanging is substantially parallel to the side surface of the door, and the matching part includes a protruding part, and the protruding part is clamped between the side surface of the door and the flanging. Thus, the end cap is designed with a protruding part to hook the flanging on the door, ensuring that the edge of the side surface of the door will not tilt outwards, ensuring the beautiful appearance of the door body, and also avoiding the collided with other components of the refrigeration appliance (such as another adjacent door) during the opening and closing of the door by the tilted door shell.

[0016] Optionally, the end cap further includes a main body part for filling the opening, and the protruding part extends from the main body part towards the part.

[0017] Optionally, the distance between the first part and the second part ranges from 10 to 12 millimeters. On the premise of ensuring the cutting effect, the size of the cutting edge is minimized as much as possible, and the end cap is used to seal the cutting edge to avoid bubble leakage and ensure the integrity of the door body appearance. Further, the end cap can be a plastic part, and the door shell can be a metal part such as sheet metal. After the end cap is assembled to the door shell, the color of the surface of the end cap exposed outside the opening can be made as close as possible to the color of the door shell by painting or other means to further ensure the appearance consistency of the door body and optimize the overall visual effect.

Detailed implementation mode

[0028] As described in the background art, in the prior art, a non-through handle groove is usually obtained by assembling multiple components, which has a high cost and complex production processes.

[0029] Specifically, at present, there are the following situations for the handle structures on the door body: 1. A separate plastic, aluminum alloy extrusion, or polyvinyl chloride (PVC) extrusion handle component, assembled on the door body; 2. A through handle structure integrally bent and formed on the door shell; 3. A door body structure in which pre-coated metal plates such as PCM and VCM-coated metal plates are respectively bent and formed into the door shell and the handle, and then assembled together through multiple connectors.

[0030] The above-mentioned situation 2 is only applicable to the manufacture of a through-type handle structure, that is, the handle groove runs through the entire side surface of the door along the extending direction. If the handle structure only exists in a partial area of the door side surface, the prior art can only adopt the manufacturing methods of the above-mentioned situations 1 and 3, manufacturing multiple components separately and then assembling them to the door shell in sequence to complete the assembly of the door handle structure. The increase in the number of components will increase the material cost and production processes, and increase the assembly complexity on the production line.

[0031] To solve the above technical problems, an embodiment of the present utility model provides a refrigeration appliance, including: a box body and a door, the box body defining at least one storage chamber, the door movably connected to the box body to open or close at least a part of the storage chamber, the door including: a door shell, including a first wall and a second wall formed by bending backward from one side edge of the first wall, the first wall being used to form the front surface of the door, the second wall including a discontinuous first part and a second part along the height direction of the door, the first part being bent to form a handle groove, and the second part being used to form the side surface of the door; an end cap disposed between the first part and the second part to block the opening between the first part and the second part.

[0032] Adopting this implementation scheme, disconnect the handle groove and the remaining part of the door shell where the handle groove is located, and block the opening formed by the disconnection with an end cap, so that different cross-sections of the opening side handle area and the non-handle area can be realized on the same bent and formed metal plate, thereby integrally manufacturing a non-through-type handle groove on the door shell. Thus, the number of components on the door is reduced, and on the basis of realizing the same functions and appearance, the component cost and the labor cost of door pre-assembly can be reduced.

[0033] To make the above-mentioned objects, features, and advantages of the present utility model more obvious and understandable, the following specifically describes the specific embodiments of the present utility model with reference to the accompanying drawings.

[0034] Figure 1 It is a schematic diagram of a refrigeration appliance 1 according to an embodiment of the present utility model.

[0035] The refrigeration appliance 1 can be, for example, a refrigerator, a cold storage cabinet, a wine cabinet, etc. Figure 1 Taking a side-by-side refrigerator as an example for exemplary display. In practical applications, the relevant designs of the door and the door handle structure in this implementation scheme can also be applied to various forms of refrigeration appliances such as multi-door refrigerators and single-door refrigerators. In practical applications, the relevant designs of the door and the door handle structure in this implementation scheme can be applied to hinged doors and can also be applied to drawer-type doors.

[0036] Figure 1 One of the doors of the side-by-side refrigerator is omitted to more clearly show the specific structure on the opposite side of the two doors, which is usually used to set the door handle structure.

[0037] For ease of description, in this embodiment, the width direction of the refrigeration appliance 1 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 thereof, wherein the front or the front side refers to the direction facing the user when the refrigeration appliance 1 is in use, and the rear or the rear side refers to the direction away from the user when the refrigeration appliance 1 is in use.

[0038] Specifically, refer to Figure 1 The refrigeration appliance 1 may include a housing 10 and a door 11, wherein the housing 10 defines at least one storage chamber 101, and the door 11 is movably connected to the front of the housing 10 to open or close at least a portion of the storage chamber 101. The storage chamber 101 may be, for example, a freezer, a refrigerator, a temperature-changing chamber, or the like.

[0039] The door 11 may include a heat-insulating space 113 (eg, Figure 8 As shown). When the door 11 closes the storage chamber 101, the insulation layer formed by the insulation space 113 has the effect of isolating heat to ensure that the storage chamber 101 has a better refrigeration / freezing effect. The door 11 may include a door shell 2, a door liner 14 facing the box body 10 when the door 11 is closed, and at least side clips 111 arranged on opposite sides of the door 11. The insulation space 113 is located between the door shell 2 and the door liner 14. The door liner 14 is also called the inner liner, which is used to form the rear surface of the door 11. In some embodiments, the door shell 2 forms at least a portion of the front boundary of the insulation space 113 so that the insulation material contacts the rear side of the door shell 2. The door 11 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 2. The front panel may be a glass plate or a ceramic plate. The door 11 in this example may be a glass door.

[0040] Further, the door shell 2 may include a first wall 21 and a second wall 22 formed by bending backward from one side edge of the first wall 21. Bending backward means bending in a direction away from the front surface 11a, and the door 11 is bent toward the box body 10 when closing at least a portion of the storage chamber 101.

[0041] For example, refer to Figure 1 and Figure 5 The first wall 21 is suitable for forming the front surface 11a of the door 11, that is, the appearance of the refrigeration appliance 1. The first wall 21a is bent backwards on both sides opposite to each other along the x direction to form the second wall 22 and the sixth wall 24. The second wall 22 at least partially forms the side surface 11b of the door 11, and the sixth wall 24 is suitable for forming the side surface 11b of the door 11. Furthermore, the sixth wall 24 is close to the hinge side 112 of the door 11, and the corresponding side where the second wall 22 is located can be regarded as the door opening side. The second wall 22 is integrally formed with a handle groove 13 in a local area along the z direction. Among them, Figure 5 The door liner 14 is omitted.

[0042] Further, edge clips 111 are respectively provided on two opposite sides of the door shell 2 in the z direction, so that the door shell 2, the door liner 14, and a pair of edge clips 111 together enclose a heat insulation space 113.

[0043] In a variant, the side surface 11b of the door 11 can also be formed by bending backward relatively from two opposite sides of the first wall 21 in the z direction, and edge clips 111 are respectively provided on two opposite sides of the door shell 2 in the x direction. The wall formed by bending the first wall 21 backward is integrally formed with a handle groove 13 at least partially in the x direction. Thus, a door handle structure can be provided at the upper edge or the lower edge of the door 11.

[0044] In a specific embodiment, referring to Figures 1 to 3 、 Figures 5 to 7 , the second wall 22 includes a discontinuous first part 221 and a second part 222 along the height direction of the door 11 (for example, the z direction). Among them, Figure 3 The door liner 14 is not shown.

[0045] Specifically, there is an opening 223 between the first part 221 and the second part 222. That is to say, the second wall 22 is disconnected, and there is a non-zero gap between the first part 221 and the second part 222. For example, after bending to obtain the second wall 22, the second wall 22 can be cut by a tool such as a cutter to obtain the discontinuous first step 221 and the second part 222.

[0046] Further, the first part 221 can be bent to form the handle groove 13. For example, during manufacturing, the initial shape of the first part 221 is the same as that of the second part 222, and the first part 221 is bent by a process such as die stamping to form a cross-sectional shape as shown in Figure 3 to integrally form the handle groove 13 on the side of the door shell 2.

[0047] Further, the second part 222 is used to form the side surface 11b of the door 11. In other words, the function of the second part 222 on the door 11 is similar to that of the sixth wall 24, except that the former does not connect the edge clips 111 on the upper and lower sides in the z direction, while the latter extends to the edge clips 111 on the upper and lower sides in the z direction.

[0048] Further, the handle groove 13 is partially formed on the side of the door 11 in the z direction. That is to say, the cross-sections of the hand-held area (i.e., the first part 221) and the non-hand-held area (i.e., the second part 222) on the side of the door 11 are different, where the cross-section refers to a plane perpendicular to the z direction.

[0049] Thus, the handle groove 13 formed on the door 11 is not the through-length handle structure introduced in the prior art, but can still be manufactured by using the integral molding process for manufacturing the through-length handle groove. Specifically, different cross-sections on the side of the door 11 no longer need to be achieved by disassembling parts, but the handle bending part (i.e., the first part 221) and the door shell bending part (i.e., the second part 222) can be combined into one part, and the two plastic parts connecting the two bending parts are cancelled.

[0050] In some embodiments, the first part 221 is located above the second part 222 in the z direction. Correspondingly, the shape of the end of the upper side edge clip 111 away from the hinge side 112 is adapted to the shape of the handle groove 13. For example, referring to Figure 5 , the handle groove 13 extends upward in the z direction to the edge clip 111 located on the upper side of the door shell 2 and stops at the opening 223 in the downward z direction.

[0051] In some other embodiments, the first part 221 can also be located below the second part 222. Correspondingly, the shape of the end of the lower side edge clip 111 away from the hinge side 112 is adapted to the shape of the handle groove 13.

[0052] In a specific implementation, referring to Figures 1 to 7 , the door 11 can further include an end cap 3, which is arranged between the first part 221 and the second part 222 to block the opening 223 between the first part 221 and the second part 222.

[0053] Specifically, the opening 223 can include a gap that connects the inside and outside of the door 11 formed by cutting a knife along the plane formed by the x direction and the y direction on the second wall 22 to disconnect the first part 221 and the second part 223. Further, the opening 223 can also include a region that is formed by bending the first part 221 and is connected to the inside and outside of the door 11 in the z direction. That is, the open mouth that connects the inside and outside of the door 11 caused by the part where the handle groove 13 is recessed into the door 11.

[0054] Further, the end cap 3 is adapted to block the opening 223 in all directions to prevent the heat insulation material from overflowing from the opening 223 during foaming. Most of the structure of the end cap 3 is hidden inside the door 11 and is more firmly combined with the door shell 2 through the heat insulation material.

[0055] For example, the end cap 3 can include a main body part 36 for filling the opening 223.

[0056] As described above, by adopting this implementation solution, the handle groove 13 and the remaining part of the door shell 3 on the side where the handle groove 13 is located are disconnected, and the opening 223 formed by the disconnection is sealed with the end cap 3, so that different cross-sections of the door handle area and the non-door handle area on the opening side can be realized on the same bent and formed metal plate, thereby integrally manufacturing the non-through handle groove 13 on the door shell 2. Thus, the number of components on the door 11 is reduced. For example, only the door shell 2 and the end cap 3 are required to form the door handle structure. On the basis of achieving the same function and appearance, the component cost and the pre-assembly labor cost of the door body can be reduced.

[0057] In a specific implementation, referring to Figures 2 to 4 , Figure 6 and Figure 7 , in the plane perpendicular to the height direction of the door 11 (that is, the plane formed by the x direction and the y direction), the cross-sectional shape of the first part 221 is different from the cross-sectional shape of the second part 222. For example, the cross-sectional shape of the first part 221 at least includes the shape of the handle groove 13, and the cross-sectional shape of the second part 222 is similar to an L shape, without multiple bends and broken lines like the first part 221.

[0058] Furthermore, the end cap 3 can (for example, along the z direction) have opposite first side 31 and second side 32. The first side 31 cooperates with the first part 221 to isolate the first part 221 and the opening 223, and the second side 32 cooperates with the second part 222 to isolate the second part 222 and the opening 223. For example, the contour shape of the first side 31 is adapted to the cross-sectional shape of the first part 221, and the contour shape of the second side 32 is adapted to the cross-sectional shape of the second part 222.

[0059] Thus, using one component to complete the transition and assembly of two different cross-sections, the number of components on the door 11 is small, which is beneficial to cost reduction and efficiency improvement.

[0060] In a specific implementation, continuing to refer to Figure 1 and Figure 2 , the end cap 3 is adapted to form the boundary of the handle groove 13 along the height direction (that is, the z direction). Specifically, in the z direction, the first side 31 of the end cap 3 closes the end of the handle groove 13 near the opening 223. Further, the end of the handle groove 13 near the edge clip 111 can be open.

[0061] In a specific implementation, continuing to refer to Figures 1 to 7 , the first side 31 can be provided with a first groove 33 to receive the edge of the first part 221 facing the opening 223. For example, the opening direction of the first groove 33 can be parallel to the z direction.

[0062] Further, the second side 32 may be provided with a second groove 34 to receive the edge of the second part 222 facing the opening 223. For example, the opening direction of the second groove 34 may be parallel to the plane formed by the x-direction and the y-direction.

[0063] In some embodiments, the first groove 33 and the second groove 34 may be arranged substantially around the main body portion 36 in an adjoining manner to seal the opening 223 in all directions. The first groove 33 opens upward around the edge of the main body portion 36 on the first side 31 and the extending shape substantially conforms to the bending shape of the first part 221. The second groove 34 is provided on the surface of the main body portion 36 perpendicular to the x-direction and the surface perpendicular to the y-direction. The first groove 33 and the second groove 34 communicate at the connection point P. The connection point P may be located, for example, at a position on the first side 31 close to the first wall 21.

[0064] During assembly, when the end cap 3 approaches the opening 223, first move the end cap 3 in the z-direction so that the edge of the first part 221 is inserted into the first groove 33. Then, buckle the second part 222 into the door 11 in the opposite direction of the x-direction so that the folded edge 25 at the edge of the second part 222 is inserted into the second groove 34. Thus, the assembly of the end cap 3 and the door shell 2 is completed.

[0065] In some embodiments, the distance that the edge of the first part 221 extends into the first groove 33 is approximately 3 millimeters (mm). Similarly, the distance that the edge of the second part 222 extends into the second groove 34 is approximately 3 mm.

[0066] Thus, the connection and cooperation between the end cap 3 and the first part 221, and between the end cap 3 and the second part 222 both adopt a plug-in design, which is beneficial for better sealing and preventing air leakage. Further, the grooves on both sides of the end cap 3 face different directions, which facilitates assembly.

[0067] In a specific implementation, with continued reference to Figure 2 、 Figure 3 and Figure 8 , the first part 221 may include a third wall 221a. The handle groove 13 is located between the first wall 21 and the third wall 221a. The third wall 221a is used to form the side surface 11b of the door 11.

[0068] Specifically, in combination with Figure 6 and Figure 7 , the handle groove 13 may include a front wall 131 and a rear wall 132 that are spaced apart along the depth direction of the door 11 (i.e., the x-direction), and a bottom wall 133 located between the front wall 131 and the rear wall 132.

[0069] Further, the front wall 131, the first wall 21, and the connecting wall 221c of the first part 221 located therebetween together form a grasping portion. The user's hand can reach into the handle groove 13 and then grasp the grasping portion, thereby conveniently operating the door 11 to open or close the storage room 101.

[0070] Furthermore, the connecting wall 221c is also adapted to form the side surface 11b of the door 11.

[0071] In some embodiments, the connecting wall 221c is closer to the inside of the door 11 than the third wall 221a, that is, the third wall 221a extends beyond the connecting wall 221c in the x direction. This is beneficial for the user to more clearly see the specific position of the door handle structure on the door 11.

[0072] In a specific implementation, referring to Figures 2 to 4 , the end cap 3 is at least partially located between the third wall 221a and the second part 222 and is visible from the outside. That is, the appearance gap caused by cutting the second wall 22 on the side of the door 11 is filled by the outer surface of the end cap 3.

[0073] Specifically, the end cap 3 may include a first surface 3a located between the third wall 221a and the second part 222. More specifically, the first surface 3a may be the surface of the main body portion 36 facing the x direction. On the side of the door 11, the first surface 3a is exposed and visible to the user, and the first surface 3a also forms a part of the side surface 11b of the door 11.

[0074] Thus, in order to form the handle groove 13 with different cross-sectional shapes and the side surface 11b of the door 11 on the side structure of the door shell 2, a cut is formed on this structure, and the end cap 3 completely seals the cut and constitutes a part of the appearance surface of the door 11. After the user opens the door 11, no obvious gap can be seen, improving the aesthetic appearance of the refrigerator.

[0075] In some embodiments, continuing to refer to Figure 2 , along the width direction of the door 11 (for example, the x direction), the third wall 221a, the first surface 3a, and the second part 222 are flush. That is to say, the three can be understood as coplanar.

[0076] Specifically, in combination with Figure 3 , Figure 4 and Figure 7 , in the region where the main body portion 36 is located on the first side 31 above the first surface 3a, the first groove 33 can be cancelled and an assembly surface 361 can be formed instead.

[0077] Furthermore, the edge of the third wall 221a facing the opening 223 can be bent inward towards the door 11 to form a folded edge 25. When the first side 31 seals the opening 223 and the first part 221, the edges of the connecting wall 221c, the front wall 131, the bottom wall 133, and the rear wall 132 facing the opening 223 are inserted into the first groove 33, and the folded edge 25 overlaps the assembly surface 361.

[0078] Thus, there is no obvious concave-convex structure on the door 11, the lines are smooth, and the appearance is beautiful. Further, since the door handle structure is usually arranged on the adjacent sides of the double doors, the design that the first surface 3a is flush with the side surface 11b of the door 11 is beneficial to avoid affecting the opening and closing of the other door.

[0079] In some embodiments, flanges 25 that bend towards the inside of the door 11 can be formed on the edges of the first part 221 and the second part 222 except for the area where the handle groove 13 is located. The flange 25 can be naturally formed when the opening 223 is cut. Further, the flanges 25 may originally exist on the edges of the handle groove 13 (i.e., the front wall 131, the bottom wall 133, and the rear wall 132) facing the opening 223 and are removed in subsequent processes. Similarly, the flanges 25 at the edges of the fourth wall 221b and the fifth wall 222a that need to cooperate with the step portion 362 can also be removed to ensure that the fourth wall 221b, the fifth wall 222a, and the second surface 3b are flush.

[0080] In some embodiments, the distance L between the first part 221 and the second part 222 can range from 10 to 12 millimeters. Specifically, the distance L refers to the interval distance between the first part 221 and the second part 222 on the side surface 11b of the door 11.

[0081] For example, L can be 10mm. Correspondingly, the dimension of the first surface 3a in the z direction is defined by the distance L to ensure that the notch on the side of the door 11 is completely filled.

[0082] Thus, on the premise of ensuring the cutting effect, the size of the cutting edge is minimized as much as possible. The cutting edge is blocked by the end cap 3 to avoid air leakage and ensure the integrity of the appearance of the door 11. Further, the end cap 3 can be a plastic part, and the door shell 2 can be a metal part such as sheet metal. After the end cap 3 is assembled to the door shell 2, the color of the surface of the end cap 3 exposed outside the opening 223 (for example, the first surface 3a) can be made as close as possible to the color of the door shell 2 by painting or other means to further ensure the appearance consistency of the door 11 and optimize the overall visual effect.

[0083] In a specific implementation, continue to refer to Figures 6 to 8 , the edge of the first part 221 away from the first wall 21 can be bent towards the inside of the door 11 to form the fourth wall 221b. The fourth wall 221b is substantially parallel to the first wall 21.

[0084] Further, the edge of the second part 222 away from the first wall 21 can be bent towards the inside of the door 11 to form the fifth wall 222a. The fifth wall 222a is substantially parallel to the first wall 21. In the y direction, the fourth wall 221b can be flush with the fifth wall 222a.

[0085] Furthermore, the end cap 3 is at least partially located between the fourth wall 221b and the fifth wall 222a and is visible from the outside. For example, the end cap 3 may include a second surface 3b located between the fourth wall 221b and the fifth wall 222a, and the second surface 3b may form the outer surface of the main body 36 along the y direction. The shape of the second surface 3b may be adapted to the shape of the gap between the fourth wall 221b and the fifth wall 222a.

[0086] Thus, the end cap 3 completely seals the opening 223 formed by cutting the side of the door shell 2 (i.e., the second wall 22) to locally manufacture the handle groove 13, preventing foam leakage during the foaming of the door 11 and also improving the overall aesthetics of the door 11.

[0087] In some embodiments, continuing to refer to Figure 6 , along the y direction, the fourth wall 221b, the second surface 3b, and the fifth wall 222a are flush.

[0088] Specifically, in combination with Figure 4 and Figure 7 , step portions 362 may be formed on both the upper and lower sides of the main body 36 at the second surface 3b. The end surface of the fourth wall 221b facing the opening 223 and the end surface of the fifth wall 222a facing the opening 223 are respectively lapped on the corresponding step portions 362, so that the fourth wall 221b, the second surface 3b, and the fifth wall 222a are substantially coplanar.

[0089] Thus, there is no obvious concave-convex structure on the door 11, the lines are smooth, and the appearance is beautiful.

[0090] In some embodiments, continuing to refer to Figure 8 , the inner door liner 14 is respectively lapped on the fourth wall 221b, the second surface 3b, and the fifth wall 222a. The flat surface (i.e., the surface where the fourth wall 221b, the second surface 3b, and the fifth wall 222a are located together) is conducive to the reliable lapping of the inner liner 14.

[0091] In a specific implementation, continuing to refer to Figure 3 , Figure 4 , Figures 6 to 8 , for at least one of the first part 221 and the second part 222, the part may be provided with a limiting part 23, and the end cap 3 may be provided with an adapting part 35, and the adapting part 35 is used to cooperate with the limiting part 23 to limit the edge of the part away from the first wall 21 from tilting away from the door 11.

[0092] This specific implementation is described in detail by taking the example that both the first part 221 and the second part 222 are provided with the limiting part 23. Specifically, the limiting part 23 may include flanges 231 formed by bending from the edges of the first part 221 and the second part 222 toward the inside of the door 11. For example, the flange 231 formed by bending from the edge of the fourth wall 221b away from the third wall 221a toward the first wall 21 is suitable for forming the limiting part 23. For another example, the flange 231 formed by bending from the edge of the fifth wall 222a away from the side surface 11b of the door 11 toward the first wall 21 is suitable for forming the limiting part 23.

[0093] The flange 231 is substantially parallel to the side surface 11b of the door 11. In practical applications, considering factors such as manufacturing tolerance, there may be a small angle between the flange 231 and the side surface 11b of the door 11.

[0094] Further, the end cover 3 may include a protrusion 351 extending from the main body 36 toward the corresponding portion. For example, the protrusion 351 may include a first protrusion located at the first side 31 and extending from the main body 36 toward the first portion 221. For another example, the protrusion 351 may also include a second protrusion located at the second side 32 and extending from the main body 36 toward the second portion 222.

[0095] Further, refer to Figure 8 , the protrusion 351 is sandwiched between the side surface 11b of the door 11 and the flange 231. For example, along the x direction, the first convex portion is sandwiched between the third wall 221a and the flange 231 located at the first portion 221, and the second convex portion is sandwiched between the side surface 11b formed by the second portion 222 and the flange 231 located at the second portion 222. It should be noted that there may be a non-zero gap between the protrusion 351 and the side surface 11b, and the protrusion 351 and the flange 231 may be mutually abutted, virtually in contact, or have a smaller gap.

[0096] The end cover 3 is designed with a protrusion 351 to hook the flange 231 on the door 11, ensuring that the edge of the side surface 11b of the door 11 (for example, the fourth wall 221b) will not be lifted outward from the door 11 (for example, lifted in the x direction away from the door 11), thereby ensuring the door 11 has a beautiful appearance and preventing the lifted door shell 2 from colliding with other parts of the refrigeration appliance 1 (such as another adjacent door 11) during the opening and closing of the door.

[0097] Thereby, the appearance of the door 11 (especially the side surface 11 b ) is ensured to be flat, thereby improving the aesthetic appearance.

[0098] In a typical application scenario, the manufacturing process of the door shell 2 described in this embodiment may include the following steps:

[0099] s1, trimming to obtain a flat door shell 2, and punching a hole 223 on one side in the width direction.

[0100] In step s2, the four edges of the flat door shell 2 are bent twice to form the side surface 11b of the door 11 and the walls (for example, the fourth wall 221b and the fifth wall 222a) for cooperating with the door liner 14. At this time, the opening 223 formed in step s1 divides one side surface 11b of the door 11 into two parts, namely the first part 221 and the second part 222. When step s2 is completed, the cross-sectional shapes of the first part 221 and the second part 222 are the same.

[0101] In step s3, the first part 221 is bent into a U shape to form the handle groove 13. When this step is completed, the cross-sectional shape of the first part 221 is different from that of the second part 222.

[0102] In step s4, the end cap 3 is installed on the door shell 2 to fill the opening 223. Specifically, first, the edge of the first part 221 is inserted into the first groove 33 along the z direction, and then the second part 222 is pressed in the opposite direction of the x direction so that the folded edge 25 of the second part 222 is inserted into the second groove 34.

[0103] Next, the side clips 111 on the upper and lower sides are installed on the door shell 2, and the structure as shown in Figure 5 can be obtained. Subsequently, through processes such as installing the door liner 14 and filling heat-insulating materials, the door 11 is manufactured.

[0104] In some embodiments, in step s3, the handle groove 13 can be obtained by bending in multiple times. In other embodiments, the handle groove 13 can be formed by one-time stamping with a mold.
