DETAILED DESCRIPTION
[0024] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.
[0025] like Figures 1 to 5 As shown, a composite vacuum insulation panel of the present invention includes a first plate body 1 and a second plate body 2; the first plate body 1 includes a first vacuum insulation panel 11 and a first polyurethane foam layer 12, the first vacuum insulation panel 11 is arranged on the outside of the first polyurethane foam layer 12, and a first connecting structure 13 is arranged on the inside of the first polyurethane foam layer 12; the second plate body 2 includes a second vacuum insulation panel 21 and a second polyurethane foam layer 22, the second vacuum insulation panel 21 is arranged on the outside of the second polyurethane foam layer 22, and a second connecting structure 23 is arranged on the inside of the second polyurethane foam layer 22, and the second connecting structure 23 cooperates with the first connecting structure 13 to connect the first plate body 1 and the second plate body 2 together.
[0026] Thus, the composite vacuum insulation panel of the present invention, when in use, aligns the first connecting structure 13 of the first panel 1 with the second connecting structure 23 of the second panel 2. The second connecting structure 23 cooperates with the first connecting structure 13 to connect the first panel 1 and the second panel 2 together. By providing the first connecting structure 13 and the second connecting structure 23, relative sliding between the first panel 1 and the second panel 2 is prevented after the first panel 1 and the second panel 2 are connected. By providing the first vacuum insulation panel 11 and the second vacuum insulation panel 21, both the upper and lower surfaces of the first panel 1 and the second panel 2 provide good insulation after the first panel 1 and the second panel 2 are connected, achieving ideal insulation performance with a relatively thin overall thickness.
[0027] Optionally, the first connecting structure 13 is a slot 131 integrally formed with the first polyurethane foam layer 12; the second connecting structure 23 is an insert 231 integrally formed with the second polyurethane foam layer 22, and the insert 231 can be inserted into the slot 131. By providing the slot 131 and the insert 231, when connecting the first plate 1 and the second plate 2, the slot 131 is aligned with the insert 231, and the insert 231 is inserted into the slot 131, thereby achieving the connection between the first plate 1 and the second plate 2.
[0028] Specifically, if Figures 1 to 3 As shown, the slot 131 is a truncated cone-shaped slot 1311, and the insert 231 is a truncated cone-shaped insert 2311. The dimensions of the truncated cone-shaped insert 2311 are consistent with those of the truncated cone-shaped slot 1311. By providing the truncated cone-shaped slot 1311 and the truncated cone-shaped insert 2311, the truncated cone-shaped insert 2311 can be quickly inserted into the truncated cone-shaped slot 1311. Since the dimensions of the truncated cone-shaped insert 2311 are consistent with those of the truncated cone-shaped slot 1311, the first plate 1 and the second plate 2 will not slide relative to each other after they are connected.
[0029] Of course, if Figure 4 and Figure 5 As shown, the slot 131 may also be a rectangular slot 1312 , and the insert 231 may also be a rectangular insert 2312 . The size of the rectangular insert 2312 is consistent with the size of the rectangular slot 1312 .
[0030] In order to further improve the thermal insulation effect, such as Figure 3 As shown, in a preferred embodiment of the present invention, a first thermal insulation coating 132 is provided on the first connection structure 13, and a second thermal insulation coating 232 is provided on the second connection structure 23. By providing the first thermal insulation coating 132 and the second thermal insulation coating 232, after the first plate body 1 and the second plate body 2 are connected, the first thermal insulation coating 132 and the second thermal insulation coating 232 are located between the first plate body 1 and the second plate body 2, so that the overall thickness is thinner while achieving the same thermal insulation effect.
[0031] In this embodiment, a first groove 14 is provided outside the first polyurethane foam layer 12 , and the first vacuum insulation panel 11 is provided in the first groove 14 ; a second groove 24 is provided outside the second polyurethane foam layer 22 , and the second vacuum insulation panel 21 is provided in the second groove 24 .
[0032] The first vacuum insulation panel 11 and the second vacuum insulation panel 21 have better thermal resistance on both the cold side and the hot side. By providing the first groove 14 and the second groove 24, the first vacuum insulation panel 11 is embedded in the first polyurethane foam layer 12, and the second vacuum insulation panel 21 is embedded in the second polyurethane foam layer 22, which can protect the corners of the vacuum insulation panels and avoid damage due to collisions. The thermal bridge of the vacuum insulation panel mainly exists on the barrier film. Using the first polyurethane foam layer 12 and the second polyurethane foam layer 22 to isolate the first vacuum insulation panel 11 and the second vacuum insulation panel 21 can block the thermal bridge of the barrier film between the first vacuum insulation panel 11 and the second vacuum insulation panel 21, thereby reducing the thermal bridge effect. At the same time, compared with vacuum insulation panels of the same thickness, such a composite vacuum insulation panel uses less material, is lighter in weight, is simpler in method, has little change in insulation performance, and reduces production costs.
[0033] The utility model also discloses a panel body comprising a vacuum insulation panel and a polyurethane foam layer, wherein the vacuum insulation panel is arranged on the outside of the polyurethane foam layer, and a connecting structure is arranged on the inside of the polyurethane foam layer. When the panel body is used, the two panels can be connected to each other to achieve a quick connection between the two panels.
[0034] like Figure 6 As shown, the utility model also discloses a refrigeration appliance door body, including a first plate body 1, a second plate body 2, an inner liner 3 and an outer shell 4; the first plate body 1 is the first plate body 1 described above, and the first plate body 1 is arranged on the inner side of the inner liner 3, the second plate body 2 is the second plate body 2 described above, and the second plate body 2 is arranged on the inner side of the outer shell 4, and the inner liner 3 is arranged on the outer shell 4 so that the first plate body 1 and the second plate body 2 are located between the inner liner 3 and the outer shell 4.
[0035] When installing the door body, first fix the first plate body 1 on the inner liner 3, then fix the second plate body 2 on the outer shell 4, and finally align the inner liner 3 with the outer shell 4 so that the first connecting structure 13 is just connected to the second connecting structure 23, so that the inner liner 3 is accurately connected to the outer shell 4. The connection process of the inner liner 3 and the outer shell 4 is simple and convenient.
[0036] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention specification and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
