Technical Field

[0001] This utility model relates to the field of refrigerators, and in particular to a hollow refrigerator door and its assembly tooling. Background Technology

[0002] With the development of technology, transparent hollow transparent door structures are being used more and more in refrigerators, such as in vending machines, where customers can directly see the beverages and food stored inside the refrigerator through the transparent door structure.

[0003] To improve the heat insulation of the hollow transparent door structure of the refrigerator, after the hollow door structure is completed, glue needs to be injected into the frame assembly through a foaming process. However, the existing frame assembly usually uses a single-port glue injection method, which is prone to uneven glue injection due to the long structure of the hollow door of the refrigerator. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a hollow refrigerator door.

[0005] A hollow refrigerator door includes: a door panel assembly; and a frame assembly connected to the outer periphery of the door panel assembly. The frame assembly has a foaming cavity that surrounds the outer periphery of the door panel assembly. The frame assembly includes at least a first foaming module located on both sides of the length direction of the door panel assembly and a second foaming module located on both sides of the width direction of the door panel assembly. Both the first and second foaming modules have chambers, and adjacent chambers are connected to form the foaming cavity. Each of the two first foaming modules has an injection hole.

[0006] With this configuration, the frame assembly and door panel assembly are set up independently, and the frame assembly is set up as a first foaming module and a second foaming module in two directions. Therefore, the first foaming module, the second foaming module and the door assembly can be processed separately, reducing the difficulty of the process and assembly. In addition, the first foaming module in the length direction is provided with glue injection holes, so glue can be injected into the cavity from two directions, thereby making the foaming inside the refrigerator hollow door more uniform and further improving the heat preservation effect of the refrigerator hollow door.

[0007] In one embodiment, the glue injection hole is covered with a cap, which is detachably connected to the wall of the glue injection hole.

[0008] In one embodiment, the first foaming module includes an end cap and a fixing beam, the end cap being connected to the fixing beam, the fixing beam being hollow and forming at least a portion of the foaming cavity, and the side of the fixing beam away from the end cap being connected to the door panel assembly.

[0009] In one embodiment, the first foaming module further includes a fixing plate and a connector. The fixing plate is located inside the fixing beam and connected to the inner wall of the fixing beam. The connector passes through the end cap, the fixing beam, and the fixing plate.

[0010] In one embodiment, the inner wall of the fixed beam near the door panel assembly is further provided with a plurality of reinforcing ribs, the plurality of reinforcing ribs extending along the width direction of the door panel assembly and being spaced apart.

[0011] In one embodiment, the first foaming module has a first snap-fit ​​portion at both ends, and the second foaming module has a second snap-fit ​​portion at both ends, and the two first foaming modules and the two second foaming modules are snap-fitted together end to end in sequence.

[0012] In one embodiment, the first latching part is configured as a latching claw, and the second latching part is configured as a latching plate, wherein the latching claw latches with the latching plate.

[0013] In one embodiment, the door panel assembly includes a base plate, a transparent plate, and a package. The transparent plate is connected to the base plate, and there are multiple transparent plates stacked along the thickness direction. The frame assembly is connected to the transparent plate, and the package is pressed onto the side of the transparent plate away from the base plate, and the package extends to the side of the frame assembly away from the base plate.

[0014] In one embodiment, the package has a mounting groove on the side away from the transparent panel, and the door panel assembly further includes a door seal that snaps into the mounting groove and abuts against the refrigerator body.

[0015] This utility model also provides an assembly fixture applicable to the hollow refrigerator door as described above. The assembly fixture further includes a mold structure that is rotatable, and the hollow refrigerator door is mounted on the mold structure.

[0016] Compared to existing technologies, this utility model allows for the independent processing of the frame assembly and door panel assembly, enabling the first foaming module, the second foaming module, and the door assembly to be processed separately. This reduces the difficulty of the process and assembly. Furthermore, the first foaming module, located along the length direction, has injection holes, allowing for injection of adhesive into the cavity from two directions. This results in more uniform foaming inside the refrigerator hollow door, further improving the insulation effect of the refrigerator hollow door. Attached Figure Description

[0031] Please see Figures 1-7 This utility model provides a refrigerator hollow door 100, in which the frame assembly 20 is injected with glue through a foaming process to improve the heat preservation effect of the refrigerator hollow door 100. Both ends of the frame assembly 20 in the length direction have glue injection holes, and glue is injected into the cavity from both directions, thereby making the foaming inside the refrigerator hollow door 100 more uniform.

[0032] The refrigerator hollow door 100 includes a door panel assembly 10 and a frame assembly 20. The frame assembly 20 is connected to the outer periphery of the door panel assembly 10. The frame assembly 20 has a foaming cavity that surrounds the outer periphery of the door panel assembly 10. The frame assembly 20 includes at least a first foaming module 21 located on both sides of the length direction of the door panel assembly 10 and a second foaming module 22 located on both sides of the width direction of the door panel assembly 10. Both the first foaming module 21 and the second foaming module 22 have chambers, and the adjacent chambers are connected to form a foaming cavity. Both first foaming modules 21 have glue injection holes. Thus, the frame assembly 20 and the door panel assembly 10 are set independently, and the frame assembly 20 is set as a first foaming module 21 and a second foaming module 22 located in two directions. Therefore, the first foaming module 21, the second foaming module 22 and the door assembly can be processed separately, reducing the difficulty of the process and assembly. In addition, the first foaming module 21 located in the length direction is provided with glue injection holes, so glue can be injected into the cavity from two directions, thereby making the foaming inside the refrigerator hollow door 100 more uniform, so as to further improve the heat preservation effect of the refrigerator hollow door 100.

[0033] Furthermore, the top cover of the injection hole is equipped with a cap 23, which is detachably connected to the wall of the injection hole. In this way, the cap 23 can seal the injection hole, preventing leakage during subsequent foaming. Moreover, because the cap 23 is detachable, it is possible to replenish the adhesive into the frame assembly 20 during later maintenance.

[0034] Specifically, the cover 23 is provided with multiple hooks, which engage with the inner wall of the cavity formed by the end cover 211 to prevent the cover 23 from coming off. At the same time, the outer periphery of the hook is provided with a bevel, so that when the hook is installed in place, the bevel allows the hook to avoid the edge of the glue injection port and partially enter the cavity.

[0035] The first foaming module 21 includes an end cap 211 and a fixing beam 213. The end cap 211 is connected to the fixing beam 213. The fixing beam 213 is hollow and forms at least a partial foaming cavity. The side of the fixing beam 213 away from the end cap 211 is connected to the door panel assembly 10. In this way, the fixing beam 213 can improve the structural strength of the first foaming module 21. The end cap 211 is used for matching with other components of the refrigerator. The end cap 211 is connected to the door panel assembly 10 through the fixing beam 213, thus facilitating the separate processing and assembly of the fixing beam 213 and the end cap 211.

[0036] The first foaming module 21 also includes a fixing plate 212 and a connector 214. The fixing plate 212 is located inside the fixing beam 213 and is connected to the inner wall of the fixing beam 213. The connector 214 passes through the end cap 211, the fixing beam 213, and the fixing plate 212. In this way, the end cap 211 is connected to the fixing plate 212 through the connector 214, and the fixing plate 212 is then separately connected to the fixing beam 213. Therefore, the end cap 211, the fixing plate 212, and the fixing beam 213 are all connected to the connector 214, resulting in a more balanced force distribution among the three components. The fixing plate 212 can also bear part of the load, making the structure stronger.

[0037] In this embodiment, the connector 214 is set as a screw or bolt, which is connected to the end cover 211, the fixing beam 213 and the fixing plate 212 in sequence from the outside of the refrigerator hollow door 100 to achieve the limiting of the three.

[0038] Specifically, the fixed beam 213 has a laterally extending slot, and the fixed plate 212 is engaged in the slot, thus being detachably connected to the fixed beam 213. Both can be machined separately and then installed together. In this embodiment, slots are constructed at both ends of the fixed beam 213 along its length, and the fixed plate 212 is engaged in each slot. Therefore, limiting structures are added from both ends of the end cap 211 and the fixed beam 213 along their length, greatly improving the connection strength between the two.

[0039] Furthermore, one end of the fixing plate 212 extends out of one end of the fixing beam 213 along its length and is bent vertically to form a flange 2121. The flange 2121 engages with the end of the fixing beam 213, thus ensuring the stability of the fixing plate 212 and preventing the fixing plate 212 from being completely inserted into the fixing beam 213, or from being installed too deep, making it unable to match the end cap 211, and difficult to remove.

[0040] Corresponding to the two fixed plates 212, both ends of the end cap 211 in the length direction are provided with receiving grooves 2112. The receiving grooves 2112 are used to accommodate the hinge structure 30. The end cap 211 is connected to the cabinet through the hinge structure 30. That is, the upper and lower first foaming modules 21 can be connected to the cabinet through the hinge structure 30 to realize the opening and closing of the refrigerator door.

[0041] The connector 214 passes through the bottom of the receiving groove 2112, and the position of the fixing plate 212 is also corresponding to the receiving groove 2112. In the vertical direction, the fixing plate 212 is located below the receiving groove 2112.

[0042] Both upper and lower first foaming modules 21 are constructed with receiving grooves 2112, and each receiving groove 2112 is provided with a hinge structure 30. The two hinge structures 30 are located on one side of the width direction of the refrigerator hollow door 100, and the side of the refrigerator hollow door 100 with the hinge structure 30 is connected to the refrigerator body.

[0043] Furthermore, in this embodiment, both ends of the first foaming module 21 in the length direction are provided with receiving grooves 2112. In one embodiment, only one side of the receiving groove 2112 is provided with a hinge structure 30. When the product requirements change and it needs to be installed on the other side of the refrigerator body, that is, when the door is opened from another direction, the two hinge structures 30 on the same side can be adjusted to the receiving groove 2112 on the other side in the width direction.

[0044] The inner wall of the fixed beam 213 near the door panel assembly 10 is further provided with multiple reinforcing ribs 2131. These reinforcing ribs 2131 extend along the width direction of the door panel assembly 10 and are spaced apart. This arrangement of reinforcing ribs 2131 increases the structural strength of the fixed beam 213. Preferably, the multiple reinforcing ribs 2131 are arranged in parallel to facilitate processing and provide more balanced support.

[0045] In other embodiments, the fixed beams 213 may also be arranged at an angle or staggered, so that multiple reinforcing beams can provide mutual support.

[0046] The first foaming module 21 has a first snap-fit ​​portion 2111 at both ends, and the second foaming module 22 has a second snap-fit ​​portion 222 at both ends. The two first foaming modules 21 and the two second foaming modules 22 are snapped together end to end. In this way, the first foaming modules 21 and the second foaming modules 22 can support each other, improving the torsional strength of the frame assembly 20. Moreover, the snap-fit ​​connection method allows the first foaming modules 21 and the second foaming modules 22 to be disassembled individually.

[0047] Furthermore, the first snap-fit ​​part 2111 is configured as a snap-fit ​​claw, and the second snap-fit ​​part 222 is configured as a snap-fit ​​plate, with the snap-fit ​​claw snapping into the snap-fit ​​plate. Thus, the connection structure between the first foaming module 21 and the second foaming module 22 is simple and stable.

[0048] The second foaming module 22 includes a vertical beam 221. The top of the vertical beam 221 is provided with the aforementioned second snap-fit ​​portion 222. The vertical beam 221 extends in the vertical direction and has a cross-section of C-shaped. It cooperates with the door assembly 10 to form a foaming cavity.

[0049] Furthermore, the door structure includes a base plate 12 and a transparent panel 11, which is connected to the base plate 12 and is made of a transparent material. A frame assembly 20 is connected to the transparent panel 11. It should be explained that the transparent material refers to the material through which the user can observe the items stored inside the refrigerator. For example, the transparent panel 11 may be made of glass or transparent plastic. In this embodiment, the base plate 12 and the transparent panel 11 are processed as two separate parts, reducing the difficulty of processing and assembly.

[0050] Preferably, at least two transparent panels 11 are provided, which are stacked and connected along the thickness direction, and both transparent panels 11 are hollow. Thus, taking the transparent panels 11 as being made of glass as an example, the stacking of two transparent panels 11 increases the overall thickness, and the overall structure consists of three layers of glass and two cavities, thereby further improving its thermal insulation performance.

[0051] Alternatively, in other embodiments, more layers of permeable panels 11 can be provided to further ensure the thermal insulation performance of the door structure.

[0052] Specifically, the permeable plate 11 is hollow and filled with argon gas. The stable chemical properties of argon gas ensure safety and improve heat insulation.

[0053] The frame structure is connected to the outer periphery of the transparent panel 11. The hollow refrigerator door 100 also includes a sealing member 13, which covers the side of the transparent panel 11 away from the substrate 12 and covers both the transparent panel 11 and the frame assembly 20, thereby sealing the outer side of the door structure. It should be noted that the outer side referred to here is the side away from the refrigerator body when the frame structure is installed on the refrigerator. Part of the sealing member 13 covers the transparent panel 11, and another part covers the frame structure, improving the connection strength and sealing performance between the two.

[0054] The side of the encapsulation component 13 away from the transparent panel 11 has a mounting groove 131. The door panel assembly 10 also includes a door seal 14, which snaps into the mounting groove 131 and abuts against the refrigerator body. In this way, the door seal 14 improves the sealing between the hollow door 100 of the refrigerator and the refrigerator body.

[0055] This utility model also provides an assembly fixture, including the refrigerator hollow door 100 as described above. The assembly fixture also includes a mold structure, which is rotatable, and the refrigerator hollow door 100 is installed on the mold structure.

[0056] Thus, after the two ends of the refrigerator hollow door 100 along its length are injected with glue, the mold can cause the refrigerator hollow door 100 to rotate and swing within a certain angle, ensuring that the liquid flows and collects well from top to bottom and from bottom to top, ensuring that the liquid fills the internal space. Especially for doors with larger dimensions, this ensures that there are no air bubbles in the upper and lower corners and the internal partitions of the side frames, ultimately achieving better heat insulation and solving the problems of poor door insulation and internal condensation.

[0057] Compared with the prior art, this utility model sets the frame assembly 20 and the door panel assembly 10 independently, allowing the first foaming module 21, the second foaming module 22 and the door assembly to be processed separately, reducing the difficulty of the process and assembly. In addition, the first foaming module 21 located in the length direction is provided with glue injection holes, so glue can be injected into the cavity from two directions, thereby making the foaming inside the refrigerator hollow door 100 more uniform, so as to further improve the heat preservation effect of the refrigerator hollow door 100.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
