Detailed Description
The present invention first provides a cabinet for a refrigerator, fig. 1 is a schematic structural view of a cabinet for a refrigerator according to one embodiment of the present invention, fig. 2 is a schematic structural exploded view of a cabinet for a refrigerator according to one embodiment of the present invention, fig. 3 is a schematic cross-sectional view of a cabinet for a refrigerator according to one embodiment of the present invention, and fig. 4 is a schematic enlarged view of a portion a of fig. 3. Referring to fig. 1 to 4, a cabinet 1 for a refrigerator according to the present invention includes a casing 10, a liner 20, and a thermal insulation layer (not shown) formed between the casing 10 and the liner 20. As is well known to those skilled in the art, the thermal insulation layer is formed by filling a foaming material between the outer shell 10 and the inner container 20.
In particular, the box 1 of the present invention further comprises a pre-buried connector 30 and a plate assembly 40. Fig. 5 is a schematic structural view of a pre-buried connection member according to an embodiment of the present invention, and fig. 6 is a schematic exploded view of a plate assembly according to an embodiment of the present invention. The embedded connector 30 is configured to be pre-installed between the inner container 20 and the outer shell 10 before forming the thermal insulation layer, and has a connection port 31 exposed to the inside of the inner container 20 through the through hole 21 on the inner container 20. The plate assembly 40 comprises a support plate 41 and a metal plate 42 arranged on the support plate 41, wherein one side of the support plate 41 departing from the metal plate 42 is provided with a connecting part 412 used for being matched with the embedded connecting piece 30. The plate assembly 40 is configured to be assembled on the liner 20 from the inside to the outside after the thermal insulation layer is formed, so that the connecting part 412 is connected to the embedded connecting part 30 through the connecting port 31, and the metal plate 42 covers at least part of the liner wall of the liner 20.
In the present invention, the direction "from the inside to the outside" is a direction from the inside of the inner container 20 to the outside of the inner container 20. It can be understood that, according to different requirements, the metal plate 42 may be disposed on the rear wall of the liner 20, and the metal plate 42 may also be disposed on the sidewall of the liner 20. When the inner container wall of the metal plate 42 is required to be provided differently, the specific direction indicated from the inside to the outside is also different. For example, when it is desired to provide the metal plate 42 on the rear wall of the liner, the direction in which the plate assembly 40 is assembled to the liner 20 (i.e., the above-described inside-out direction) is from front to back; when it is desired to provide the metal plate 42 on the left sidewall of the liner, the assembly direction of the plate assembly 40 to the liner 20 (i.e., the above-mentioned inside-outside direction) is from right to left; when it is desired to provide the metal plate 42 on the right sidewall of the liner, the assembly of the plate assembly 40 to the liner 20 is in a direction from left to right (i.e., the inside-out direction described above).
The inventor realizes that most of the inner containers are formed by adsorption, and the structures such as buckles, claws and the like cannot be directly formed on the inner container due to the limitation of the adsorption forming process. For this purpose, before the thermal insulation layer is formed (i.e. before foaming), a pre-embedded connector 30 is pre-installed between the inner container 20 and the outer shell 10. After foaming, the embedded connecting piece 30 is wrapped in the heat insulation layer, so that the structure is firm. The embedded connector 30 has a connection port 31 exposed to the inner container 20, and the support plate 41 supporting the metal plate 42 can be directly connected to the embedded connector 30 through the connection port 31, so that the metal plate 42 covers at least a part of the inner container wall of the inner container 20.
Because the connection position between metal sheet 42 and backup pad 41 is located the rear side of metal sheet 42, and metal sheet 42 passes through backup pad 41 and ground joint in inner bag 20 indirectly, consequently, need not set up any screw hole on the metal sheet 42 and can fix on inner bag 20 through very firm stable joint mode, improved the aesthetic measure of box 1 inner space and the steadiness that metal sheet 42 was fixed. Meanwhile, the plate assembly 40 formed by assembling the metal plate 42 and the support plate 41 is assembled on the inner container 20 after the box body 1 is foamed, after foaming, a heat insulation layer with a very stable structure is formed between the inner container 20 and the shell 10, the inner container 20 is not easy to deform after being stressed, and the operability of the assembly plate assembly 40 is greatly improved, so that the assembly operation is convenient for workers to implement.
In some embodiments, the metal plate 42 includes a main plate body 421 and a bendable piece 422 extending from an edge of the main plate body 421 to a direction close to the support plate 41. The bendable pieces 422 are used for bending to abut against the surface of the supporting plate 41 after the main plate 421 is attached to the supporting plate 41, so as to fix the metal plate 42 on the supporting plate 41.
Further, the main plate body 421 has a continuous, complete and flat inward surface, and the inward surface of the main plate body 421 means a surface of the main plate body 421 facing the inner side of the inner container 20, that is, a surface of the metal plate 42 exposed to the inside of the inner container 20. The inward surface of the main board 421 is continuous, complete and flat, and has no any opening, groove, pit or protrusion, further improving the beauty of the inner space of the box 1.
In some embodiments, the pre-embedded connector 30 is pre-installed on the inner container 20 from the outside to the inside, the head portion 30a of the pre-embedded connector 30 is inserted into the through hole 21 of the inner container 20, and the tail portion 30b of the pre-embedded connector 30 is located between the inner container 20 and the outer shell 10. The "outside-in" in the present invention is the direction from the outside of the inner container 20 to the inside of the inner container 20, which is the opposite direction to the direction indicated by the "inside-out" in the above description. When the inner container wall of the metal plate 42 needs to be provided with different walls, the specific directions indicated from the outside to the inside are also different, and the description is omitted here.
Further, the middle part of the embedded connecting piece 30 is provided with a skirt part 32 which protrudes and extends outwards along the radial direction of the embedded connecting piece, and the skirt part 32 is adhered to the outer surface of the rear wall of the inner container 20 through double-sided adhesive foam 51. Therefore, the stability of preassembling between the embedded connecting piece 30 and the inner container 20 is improved, and the embedded connecting piece 30 is prevented from shifting or deviating during foaming. It is understood that the outward surface of the liner 20 means the surface of the liner 20 facing outward, i.e., the surface of the liner 20 facing the casing 10.
In some embodiments, the pre-buried connecting member 30 is a rotating body with a hollow interior and two open ends, the rotating body has an annular rib 33 inside, and the connecting portion 412 is connected to the annular rib 33 in a clamping manner. The box 1 further comprises a cap 60, and the cap 60 is used for sealing the outer port 34 of the rotating body between the inner container 20 and the outer casing 10 to prevent foaming material from overflowing through the outer port. Specifically, the cap 60 may be a corrugated paper tape, an injection molded part, or any other suitable part capable of sealing the outer port 34.
According to the invention, the embedded connecting piece 30 is set as the rotating body, and the annular convex rib 33 for being clamped with the connecting part is formed in the embedded connecting piece, so that no direction limitation is caused on the embedded connecting piece 30 when the embedded connecting piece 30 is assembled, an operator does not need to judge the direction to assemble the embedded connecting piece directly, and the assembly efficiency of the box body 1 is improved.
Further, the connecting portion 412 may include at least one elastic claw, and the elastic claw and the head portion of the embedded connector 30 are provided with guide slopes, so that when the operating personnel assemble the embedded connector 30, the position of the embedded connector 30 can be easily found even in a blind assembly state (the positions of the connecting portion 412 and the embedded connector 30 cannot be seen), and the elastic claw is smoothly connected to the annular rib 33 in a clamping manner. Meanwhile, the connection part 412 and the embedded connection part 30 can limit the support plate 41 in the up-down, left-right and front-back directions.
Fig. 7 is a schematic structural view of a buried connector according to another embodiment of the present invention, fig. 8 is a schematic sectional view of a plate assembly assembled with the buried connector shown in fig. 7, and fig. 9 is a schematic exploded view of the plate assembly according to another embodiment of the present invention. In other embodiments, referring to fig. 7 to 9, the inside of the embedded connector 30 is hollow, the head portion 30a of the embedded connector 30 is open to form the connection port 31, and the tail portion of the embedded connector 30 is closed. The inside of built-in connector 30 has along the bar fin 35 that predetermines the direction extension, and connecting portion 412 joint is in bar fin 35. Because the tail part of the embedded connecting piece 30 is positioned between the inner container 20 and the outer shell 10 and is closed, the foaming material can be prevented from overflowing without the sealing of other sealing pieces, and the structure is simplified.
The applicant has appreciated that if one end of the fastener insert 30 is closed to eliminate the need for a seal, the process of forming the fastener insert 30 inevitably results in ribs that are not annular but are strips having a certain orientation. In order to ensure the accurate clamping direction between the connecting part 412 on the supporting plate 41 and the strip-shaped ribs 35, the head of the embedded connecting piece 30 and the through hole 21 on the liner 20 are further configured to have a shape matched with each other, so that only the head of the embedded connecting piece 30 is allowed to be inserted into the through hole 21 according to a set direction, and the strip-shaped ribs 35 extend in a preset direction.
Specifically, the head of the embedded connector 30 and the through hole 21 on the liner 20 may be both substantially square, and a chamfer may be provided only at a part of the corners thereof to limit the insertion direction of the embedded connector 30.
Further, the connecting portion 412 may include at least one elastic claw, and the elastic claw and the head of the embedded connector 30 are both provided with a guide slope, so that when the assembly is performed by an operator, even if the assembly is in a blind assembly state (the positions of the connecting portion 412 and the embedded connector 30 cannot be seen), the position of the embedded connector 30 can be easily found, and the elastic claw is smoothly connected to the strip-shaped rib 35 in a clamping manner. Meanwhile, the connection part 412 and the embedded connection part 30 can limit the support plate 41 in the up-down, left-right and front-back directions.
It will be appreciated that since the connection structure between the support plate 41 and the embedded connector 30 is covered by the metal plate 42, the operator is completely in a blind-mounted state when assembling the panel assembly 40. Also, the area of the plate assembly 40 is relatively large, making it more difficult to align the position. Therefore, in order to improve the assembly efficiency, in some embodiments, the box body 1 further includes a pre-buried locating member 70. Fig. 10 is a schematic structural view of an embedded positioning member according to an embodiment of the present invention, and fig. 11 is a schematic cross-sectional view of a plate assembly assembled with the embedded positioning member shown in fig. 10. The pre-embedded spacers 70 are configured to be pre-installed on the liner 20 prior to forming the thermal insulation layer. That is to say, the embedded positioning element 70 is also pre-installed on the inner container 20 before foaming, like the embedded connecting element 30, and after foaming, the tail of the embedded positioning element 70 is wrapped in the heat insulation material, so that the fixation is firm.
Correspondingly, referring to fig. 9 and 11, the side of the support plate 41 away from the metal plate 42 is further provided with a positioning portion 413 for being matched with the embedded positioning element 70, and the plate assembly 40 is configured to be positioned by matching the positioning portion 413 with the embedded positioning element 70 in the process of being assembled to the liner 20, and then the connection portion 412 is enabled to be connected with the embedded connection element 30, so that the position between the connection portion 412 and the embedded connection element 30 is found more easily, and the assembly efficiency is improved.
In some embodiments, the pre-embedded positioning element 70 is a rotating body, and there is no orientation limitation on the pre-embedded positioning element 70 when the pre-embedded positioning element 70 is assembled, so that an operator does not need to judge the direction to directly assemble the pre-embedded positioning element, and the assembly efficiency of the box body 1 is improved.
Further, the embedded positioning element 70 includes a cap portion 71 located inside the inner container 20, the cap portion 71 and the inward surface of the inner container 20 are spaced to form a positioning groove 72, and the positioning portion 413 is clamped into the positioning groove 72 from bottom to top. The inward facing surface of bladder 20 means the surface of bladder 20 facing the interior thereof.
Further, the embedded positioning member 70 further includes a rod portion 73 located between the inner container 20 and the outer shell 10 and a skirt portion 74 extending radially outward from the rod portion 73, wherein the skirt portion 74 is adhered to the outward surface of the inner container 20 through the double-sided adhesive foam 52. Therefore, the stability of preassembly between the pre-embedded positioning piece 70 and the inner container 20 is improved, and the pre-embedded positioning piece 70 is prevented from shifting or deviating during foaming. The outward surface of the inner container 20 means the surface of the inner container 20 facing the outside thereof, i.e., the surface facing the casing 10.
Specifically, the embedded locator 70 may be positioned above the embedded connector 30 to facilitate assembly. The embedded positioning member 70 can be used with the embedded connector 30 shown in fig. 7, or with the embedded connector 30 shown in fig. 5.
It should be understood that the number of the pre-embedded connectors 30, the pre-embedded positioning members 70, and the bendable pieces 422 may be one or more, and correspondingly, the number of the connecting portions 412, and the number of the positioning portions 413 may also be one or more.
The invention also provides a preparation method for the box body described in any embodiment, which comprises the following steps:
preassembling the inner container 20, the outer shell 10 and the embedded connecting piece 30 together to form a preassembly;
foaming the pre-assembly part to form a heat insulation layer between the inner container 20 and the outer shell 10, and enabling the pre-embedded connecting piece 30 to be positioned in the heat insulation layer; and
the preassembled plate assembly 40 is assembled to the liner 20 from the inside out.
The pre-embedded connector 30 is pre-installed between the inner container 20 and the outer shell 10 before foaming, so that a relatively stable connection structure is formed.
