Description

Technical Field

[0001] The utility model relates to the field of refrigerators, in particular to an anti-deformation shell of a vacuum refrigerator. Background Art

[0002] Current vacuum refrigerators require evacuating the interior of the refrigerator to create a vacuum or negative pressure environment to prolong the storage life of items. This constant vacuuming and pressure relief during use can easily cause the refrigerator's housing to deform, affecting its structural strength and, consequently, its lifespan and aesthetics. Utility Model Content

[0003] In order to solve the technical problem that repeated vacuuming of a vacuum refrigerator in the prior art easily affects the structural strength of the shell, the utility model provides an anti-deformation shell of a vacuum refrigerator.

[0004] A vacuum refrigerator anti-deformation shell, the shell comprising a main box body and a box door adapted to the main box body, the main box body comprising an inner shell and an outer shell, a rib frame being provided between each side of the inner shell and the outer shell, the rib frame being a grid-like frame composed of two or more transverse ribs and two or more longitudinal ribs interwoven; glue holes being provided on the longitudinal ribs between adjacent transverse ribs and on the transverse ribs between adjacent longitudinal ribs; one side of the rib frame being fixedly connected to the inner shell; the other side being fixedly connected to the outer shell; the outer shell being provided with a glue injection hole; and the space between the inner shell and the outer shell being filled with foam glue.

[0005] In a preferred embodiment of the anti-deformation shell of the vacuum refrigerator provided by the present invention, studs are provided at both ends of the transverse ribs and the longitudinal ribs, as well as at the intersection of the transverse ribs and the longitudinal ribs, and threaded holes are provided on the studs. The shell is fixedly connected to the threaded holes by screws.

[0006] In a preferred embodiment of the anti-deformation housing of the vacuum refrigerator provided by the present invention, a nut cover is provided at the nut of the screw.

[0007] In a preferred embodiment of the anti-deformation housing of the vacuum refrigerator provided by the present invention, the rib frame is an integrated frame made of plastic material.

[0008] Compared with the prior art, the anti-deformation shell of the vacuum refrigerator provided by the present invention reinforces the structural strength of the main box body through the setting of the rib frame, thereby preventing the main box body from being deformed due to repeated vacuuming and pressure relief operations; through the setting of the studs, the intersection of the longitudinal ribs and the transverse ribs is reinforced while fixing the outer shell, so that the inner shell, the rib frame and the outer shell are tightly connected and reinforce each other; through the setting of the glue holes, when the foam glue is injected between the inner shell and the outer shell, the foam glue can fill every place between the inner shell and the outer shell; the rib frame is made of plastic material, which effectively reduces heat conduction between the inner shell and the outer shell; through the setting of the nut cover, the nut of the outer shell is made more beautiful. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 This is a structural diagram of the anti-deformation shell of the vacuum refrigerator provided by the utility model;

[0010] Figure 2 yes Figure 1 Enlarged view of point A in the middle. DETAILED DESCRIPTION

[0011] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0012] Please refer to Figure 1 and Figure 2 , respectively, are the structural diagrams of the anti-deformation shell of the vacuum refrigerator provided by the utility model and Figure 1 Enlarged view of point A in the middle.

[0013] The anti-deformation shell of the vacuum refrigerator includes a main box body (not shown in the figure) and a door (not shown in the figure) adapted to the main box body.

[0014] The main box body includes an outer shell 1 and an inner shell 2, which together form the main box body. An integral rib frame 3 made of plastic is provided between the back of the inner shell 2 and the four sides adjacent to the opening and the outer shell 1.

[0015] The rib frame 3 comprises a grid-like frame formed by interweaving five transverse ribs and four longitudinal ribs. Studs 31 are located at each end of each transverse and longitudinal rib, as well as at their intersections. These studs 31 have threaded holes 32, and the outer shell 1 is fixedly connected to these threaded holes 32 via screws. These screws are fitted with nut caps (not shown). The inner shell 2 is fixedly welded to the rib frame 3 using plastic welding.

[0016] The longitudinal ribs between adjacent transverse ribs and the transverse ribs between adjacent longitudinal ribs are provided with glue holes 21. The housing 1 is provided with glue injection holes (not shown). For aesthetic reasons, the glue injection holes are provided with plugs (not shown).

[0017] The space between the inner shell 2 and the outer shell 1 is filled with foam glue (not shown in the figure).

[0018] During implementation, the inner plate frame 3 is first welded to the inner shell 2, and then the outer shell 1 is fixedly connected to the screw holes 32 of the inner plate frame 3 using screws. The prepared foam glue is injected between the inner shell 2 and the outer shell 1 through the glue injection hole, flows through the glue holes 21 into each grid of the inner plate frame 3, and fills the space between the inner shell 2 and the outer shell 1. The foam glue is allowed to solidify. The nut cap covers the nut, and the plug cap covers the glue injection hole.
