Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, for example, to a door structure for a refrigerator and a refrigerator. Background Art

[0002] Open foaming refers to applying a liquid foaming agent to the surface of the material to cause a chemical reaction, causing the foaming agent to expand and form a foam. The open foaming process is preferably used in the manufacture of refrigerator door bodies due to its advantages such as low cost, convenient construction, and high speed. In the process of manufacturing the refrigerator door body through the open foaming process, the door shell and the door lining need to be set separately first, and after applying the foaming agent to the door shell, the door lining is filmed to the door shell. However, when the refrigerator door body has electronic components such as cameras or light components, it is necessary to pre-set the wire body in the foaming space.

[0003] Specifically, the door shell and the door lining are first separately arranged, the output end of the wire body passes through the threading hole on the door lining and is fixed to the door lining, and the input end of the wire body passes through the threading hole on the door shell and is exposed to the outside of the door shell. Since the output end and input end of the wire body are respectively installed on the door lining and the door shell, this process results in a longer wire body being reserved in the foaming space. After the foaming agent is applied to the door shell and the door lining is filmed onto the door shell. Assemblers are required to hold the input end of the wire body and pull out the excess wire body from the foaming space in time through the threading hole on the door shell to avoid too much wire body being retained in the foaming space and affecting the foaming effect. This process requires manual operation, resulting in high labor intensity in assembling the door body of the refrigerator with wire body.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0044] In some embodiments, in combination Figures 1 to 3As shown, a door structure 1 for a refrigerator is provided, comprising a door shell 10, a wire support 20, a connecting wire 30 and a door lining 40. The door shell 10 defines a foaming space 110 for injecting foaming material. The wire support 20 comprises a supporting portion 210, which is arranged on the door shell 10 and located in the foaming space 110. The connecting wire 30 is located in the foaming space 110, and the output end of the connecting wire 30 is arranged on the supporting portion 210 of the wire support 20. The door lining 40 comprises a through portion 410, which is arranged to be molded to the door shell 10 after the foaming material is injected into the foaming space 110 of the door shell 10. After the door lining 40 is molded to the door shell 10, the supporting portion 210 is butted with the through portion 410, so that the output end of the connecting wire 30 arranged on the supporting portion 210 can be exposed to the through portion 410.

[0045] The door structure 1 provided by the embodiment of the present disclosure, by setting the wire support 20 on the door shell 10 and being located in the foaming space 110, and then setting the output end of the connecting wire 30 on the supporting part 210, allows the connecting wire 30 to be directly installed on the door shell 10 before the door lining 40 is molded to the door shell 10. Compared with the related art, the output end of the connecting wire 30 does not need to be set on the door lining 40. Therefore, there is no need to reserve a longer connecting wire 30, so that the connecting wire 30 can be pre-installed in place directly in the foaming space 110 before the foaming material is injected, thereby eliminating the subsequent manual wire pulling process and reducing the labor intensity of the refrigerator door assembly. In addition, after the door lining 40 is molded to the door shell 10, the supporting part 210 is connected to the through part 410, and the output end of the connecting wire 30 set on the supporting part 210 can be exposed to the through part 410, so that the assembly personnel can connect and set the electronic components and the output end of the connecting wire 30, and the operation is simple.

[0046] Optionally, combined Figure 3 , Figure 4 and Figure 6 As shown, the supporting portion 210 includes a docking wall 216 . The docking wall 216 docks with the through portion 410 , and a guide groove 214 is formed on the docking wall 216 , and the output end of the connecting line 30 is disposed in the guide groove 214 .

[0047] In this embodiment, a guide groove 214 is provided on the docking wall 216 of the supporting portion 210, and the guide groove 214 is used to guide the installation of the output end of the connecting wire 30. By installing the output end of the connecting wire 30 in the guide groove 214, the connecting wire 30 can be positioned and arranged before the foaming material is injected. At the same time, the output end of the connecting wire 30 is arranged in the guide groove 214, so that the output end of the connecting wire 30 can be protected to prevent the heat emitted during the chemical reaction and expansion of the foaming agent from damaging the output end of the connecting wire 30.

[0048] Optionally, combined Figure 4 and Figure 6As shown, the supporting portion 210 includes a supporting plate 212. The supporting plate 212 includes a foaming surface arranged opposite to the docking wall surface 216. The supporting plate 212 extends from the docking wall surface 216 toward the foaming surface, and a guide groove 214 is formed on the docking wall surface 216 side.

[0049] In this embodiment, the supporting portion 210 includes a supporting plate 212, and the supporting plate 212 includes a docking wall 216 and a foaming surface that are arranged opposite to each other. The docking wall 216 docks with the through portion 410. After the liquid foaming agent expands to form a foam body, the foaming surface abuts against the foam body. Extending from the docking wall 216 toward the foaming surface, the supporting plate 212 forms a guide groove 214 on the side of the docking wall 216. The guide groove 214 is formed integrally on the supporting plate 212 to improve the structural strength of the supporting portion 210 and improve the reliability of the wire support 20.

[0050] Optionally, combined Figure 3 , Figure 4 and Figure 6 As shown, the guide groove 214 extends along the length or width direction of the door structure 1 , and one end of the guide groove 214 passes through the supporting plate 212 and communicates with the foaming space 110 .

[0051] In this embodiment, one end of the guide groove 214 is connected to the foaming space 110. The structure in which the guide groove 214 is connected to the foaming space 110 facilitates the assembler to place the output end of the connecting wire 30 in the guide groove 214 and arrange the connecting wire 30 along the direction extending from the guide groove 214 toward the connecting part.

[0052] Optionally, combined Figure 4 and Figure 6 As shown, the wire support 20 further includes a support portion 220. The first end 222 of the support portion 220 is connected to the door shell 10, and the second end 224 is connected to the supporting portion 210. The second end 224 of the support portion 220 extends toward the door lining 40 so that after the door lining 40 is molded to the door shell 10, the supporting portion 210 is butted against the through portion 410.

[0053] In this embodiment, the wire support 20 includes a supporting portion 220 and a holding portion 210. The holding portion 210 is used to hold the output end of the connecting wire 30. The supporting portion 220 is used to support the holding portion 210, so that after the door lining 40 is molded to the door shell 10, the holding portion 210 is docked with the through portion 410. The supporting portion 220 is provided to support the holding portion 210, so as to avoid the foaming material covering the supporting portion 210 and then covering the output end of the connecting wire 30 during the process of injecting the liquid foaming material into the foaming space 110. By reducing the probability that the foaming material covers the supporting portion 210 and the output end of the connecting wire 30 during the process of injecting the foaming material, damage to the output end of the connecting wire 30 is avoided, thereby improving the safety of the manufacturing process of the refrigerator door structure.

[0054] Optionally, combined Figure 4 and Figure 6 As shown, the support portion 220 includes a foaming cavity 226 and a communication port 228. The communication port 228 is located at the peripheral side of the support portion 220, and the foaming cavity 226 and the foaming space 110 are connected through the communication port 228.

[0055] In this embodiment, the foaming cavity 226 of the support portion 220 is connected with the foaming space 110 through the connecting port 228. By connecting the foaming cavity 226 with the foaming space 110, it is convenient to inject foaming material into the foaming space 110, and the liquid foaming material can enter the foaming cavity 226 through the connecting port 228, or after the foaming material expands to form a foam body, the foam body can cover the foaming cavity 226. By making the foam body cover the foaming cavity 226, the distribution uniformity of the foam body between the door lining 40 and the door shell 10 is improved, and the thermal insulation effect of the door structure 1 is improved.

[0056] Optionally, combined Figure 4 and Figure 6 As shown, there are a plurality of communication openings 228 , and the plurality of communication openings 228 are spaced apart and located around the support portion 220 .

[0057] In this embodiment, there are multiple communication openings 228. By increasing the number of communication openings 228, the through area between the foaming cavity 226 and the foaming space 110 is increased, so that the liquid foaming material can enter the foaming cavity 226, or after the foaming material expands to form a foam body, the coverage rate of the foam body on the foaming cavity 226 is increased.

[0058] It should be noted that the number, shape, size and distribution of the communication ports 228 need to be specifically set by technical personnel based on actual product equipment and are not specified here.

[0059] Optionally, combined Figure 4 and Figure 6 As shown, the line support 20 further includes a positioning portion 230. The positioning portion 230 is disposed at the first end 222 of the support portion 220, and the support portion 220 is fixedly connected to the door shell 10 through the positioning portion 230.

[0060] In this embodiment, the wire support 20 includes a supporting portion 210, a supporting portion 220 and a positioning portion 230. The supporting portion 220 includes a first end 222 and a second end 224 that are arranged opposite to each other. The positioning portion 230 is located at the first end 222, and the supporting portion 210 is located at the second end 224. The supporting portion 210 is used to support the output end of the connecting line 30, the supporting portion 220 is used to support the supporting portion 210, and the positioning portion 230 is used to connect the supporting portion 220 and the door shell 10, so that the wire support 20 is fixedly arranged on the door shell 10. By setting the positioning portion 230, the connection strength between the wire support 20 and the door shell 10 is improved, and the structural stability of the refrigerator door is improved.

[0061] Optionally, combined Figure 4 and Figure 6 As shown, the first end 222 of the support portion 220 is in an open cylindrical shape. A flange extending from the circumferential edge of the opening toward the radial outer side of the opening is formed at the opening of the first end 222 of the support portion 220 to form a positioning portion 230 .

[0062] In this embodiment, a flange extending from the circumferential edge of the opening toward the radially outer side of the opening is formed at the opening of the first end 222 of the support portion 220, thereby forming a positioning portion 230. The positioning portion 230 is used to connect the support portion 220 and the door shell 10, so that the wire support 20 is fixedly arranged on the door shell 10. By forming a flange structure, the contact area between the positioning portion 230 and the door shell 10 is increased, thereby improving the connection strength between the positioning portion 230 and the door shell 10. In addition, the structural strength of the wire support 20 is improved by integrally forming the support portion 220 and the positioning portion 230. By improving the connection strength between the positioning portion 230 and the door shell 10, the structural strength of the wire support 20 is improved, thereby further improving the structural stability of the refrigerator door.

[0063] Optionally, combined Figures 1 to 5 As shown, the through portion 410 includes a through hole 412. The through hole 412 is configured to be connected to the guide groove 214 after the door liner 40 is molded to the door shell 10. The output end of the connection line 30 is exposed in the through hole 412.

[0064] In this embodiment, the through portion 410 includes a through hole 412. After the door liner 40 is molded to the door shell 10, the through hole 412 is connected to the guide groove 214. After the door liner 40 is molded to the door shell 10, the through hole 412 is connected to the guide groove 214, so that the output end of the connecting wire 30 located in the guide groove 214 can be exposed in the through hole 412. When the assembler is performing the connection setting between the electronic component and the output end of the connecting wire 30, the output end of the connecting wire 30 can be directly taken out through the through hole 412 to connect the electronic component, which is simple to operate.

[0065] Optionally, combined Figures 1 to 5 As shown, the shape and size of the through hole 412 are the same as the shape and size of the guide groove 214 parallel to the cross section of the door shell 10 .

[0066] In this embodiment, by setting the shape and size of the through hole 412 to be the same as the shape and size of the cross section of the guide groove 214 parallel to the door shell 10, the through area between the through hole 412 and the guide groove 214 is increased to avoid the phenomenon that the output end of the connecting wire 30 cannot be exposed in the through hole 412 due to the small through area between the through hole 412 and the guide groove 214, or the output end of the connecting wire 30 is exposed in the through hole 412 for a short length, which makes it inconvenient for assemblers to connect electronic components.

[0067] It should be noted that the shape and size of the through hole 412 may be different from the shape and size of the cross section of the guide groove 214 parallel to the door shell 10. The specific shape and size of the guide groove 214 and the through hole 412 need to be set by the technicians according to the actual product equipment, and are not specified here, as long as the output end of the connecting wire 30 located in the guide groove 214 can be exposed in the through hole 412 after the door lining 40 is molded to the door shell 10, and the length of the exposed connecting wire 30 is convenient for the assembler to connect the electronic components.

[0068] Optionally, combined Figure 1 and Figure 2 As shown, the door liner 40 includes a first side surface 420 and a second side surface 430 that are oppositely disposed. Extending from the first side surface 420 toward the second side surface 430 , the door liner 40 forms a groove on the first side surface 420 to form a through portion 410 .

[0069] In this embodiment, a groove is formed on the first side 420 of the door liner 40, extending from the first side 420 toward the second side 430, to form a through portion 410. The through portion 410 is formed integrally on the door liner 40 to improve the structural strength of the door liner 40, thereby further improving the structural stability of the door body of the refrigerator 2 and the reliability of the door body structure 1.

[0070] Optionally, combined Figure 1 and Figure 3 As shown, the door shell 10 includes a door frame 120 and a door panel 130. The door frame 120 and the door panel 130 define a foaming space 110. The wire support 20 is provided on the door panel 130. After the door lining 40 is molded to the door shell 10, the door lining 40 is connected to the door frame 120. The door frame 120 is provided with a threading hole 122. The input end of the connecting wire 30 passes through the threading hole 122 and is exposed outside the foaming space 110.

[0071] In this embodiment, the door frame 120 is provided with a threading hole 122. Before the door lining 40 is molded to the door shell 10, the output end of the connecting wire 30 is arranged on the supporting portion 210, and the input end of the connecting wire 30 passes through the threading hole 122 and is exposed outside the foaming space 110. By arranging the output end of the connecting wire 30 on the supporting portion 210 of the wire body bracket 20, the input end of the connecting wire 30 is passed through the threading hole 122 of the door shell 10, and the wire body bracket 20 is arranged on the door shell 10, the connecting wire 30 is directly arranged on the door shell 10 before the door lining 40 is molded to the door shell 10. Compared with the related art, the output end of the connecting wire 30 does not need to be arranged on the door lining 40, so there is no need to reserve a long connecting wire 30, which also avoids the subsequent manual wire pulling process, reduces the labor intensity of the door body assembly of the refrigerator 2, and improves the assembly efficiency of the door body of the refrigerator 2.

[0072] In some embodiments, in combination Figure 7 As shown, a refrigerator 2 is provided, comprising a box body 3 and a door structure 1 for a refrigerator as described in any of the above embodiments. The door structure 1 is rotatably connected to the box body 3 and is used to open or close the box body 3.

[0073] The refrigerator 2 provided in the embodiment of the present disclosure includes a door structure 1 for a refrigerator as described in any of the above embodiments, and the door structure 1 is rotatably connected to a box body 3. Since the door structure 1 provided in the present disclosure eliminates the process of manual wire pulling during the assembly process, the labor intensity of refrigerator door assembly is reduced and the assembly efficiency of the refrigerator door is improved. By reducing the labor intensity of refrigerator door assembly and improving the assembly efficiency of the refrigerator door, the labor intensity of refrigerator manufacturing is reduced, and the assembly efficiency and automation of the refrigerator are improved.
