Detailed Description

As shown in fig. 1-4, one aspect of an embodiment of the present invention relates to an insulation member 10, comprising: a housing 12 made of plastic material and including a space 14 disposed therein; and an inert gas 16 located in the space 14.

The insulation 10 can be applied to various structures requiring insulation, such as a cabinet of a refrigerator.

The housing 12 may be made of plastic such as polyvinyl chloride (PVC), High Impact Polystyrene (HIPS), and the like. The plastic housing 12 with the interior space 14 can help to provide the insulation 10 with a lighter weight and lower cost. The high-strength plastic materials such as polyvinyl chloride (PVC) and High Impact Polystyrene (HIPS) are favorable for reducing the wall thickness of the housing 12, reducing the heat conduction path of the heat insulating member 10, and improving the heat insulating performance of the heat insulating member 10.

The space 14 may be formed by means of blowing. The housing 12 may be a hollow plate surrounded by a plurality of outer walls 13, and the space 14 may extend between the outer walls 13.

The inert gas 16 may enter and remain in the space 14 by any suitable means. In some embodiments, the housing 12 includes a gas flushing port 18 in fluid communication with the space 14. Inert gas 16 may enter the space 14 through a gas flushing port 18. After the inert gas 16 is injected, the injection opening 18 may be closed with a plug (not shown) or a stopper (not shown) having a sealing ring, and then a sealant may be applied for secondary sealing. The purge orifice 18 may be closed after the purge of inert gas 16 is completed in other ways.

Other structures may be included between the outer walls 13 of the housing 12. In some embodiments, referring to fig. 5 and 6, the housing 12 includes a porous structure 20, and the porous structure 20 includes a space 14. The porous structure 20 may help to improve the mechanical strength of the housing 12, the insulation 10.

The porous structure 20 may be of any suitable shape and configuration, and may be arranged in a single layer, or may be arranged in multiple layers, and may be arranged regularly or irregularly. In some embodiments, the porous structure 20 includes a plurality of side-by-side tubes 22. The side-by-side conduits 22 may help facilitate manufacture of the housing 12. The cross-section of the conduit 22 may be various shapes such as circular, oval, etc., so that the porous structure 20 may have pores of various shapes such as circular pores, oval pores, etc.

In some embodiments, the inert gas 16 includes at least one of helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and gas oxygen (Og). The inert gas 16 has a lower thermal conductivity than air, vacuum, etc., and may help to improve the thermal insulation properties of the thermal insulation member 10. Moreover, even if moisture enters the space 14, the influence of the moisture on the heat insulating performance of the heat insulating member 10 is very limited due to the presence of the inert gas 16 having high stability, so that the heat insulating stability of the heat insulating member 10 is high.

As shown in fig. 7-9, another aspect of the embodiment of the present invention relates to a refrigerator 50 comprising a cabinet 52, the cabinet 52 comprising a housing 54, a liner 56, and a thermal insulation material 58 and the thermal insulation 10 as described above between the housing 54 and the liner 56.

The heat insulator 10 can contribute to a reduction in the use of the heat insulating material 58, and the sum of the thicknesses of the heat insulator 10 and the heat insulating material 58 can be considerably reduced with respect to the thickness of the heat insulating material when only the heat insulating material is used, for the same heat insulating effect, and therefore, the heat insulator 10 can contribute to a reduction in the thickness of the cabinet 52 of the refrigerator 50, and an increase in the effective use space of stored articles. Moreover, the thermal insulation member 10 may be beneficial to improve the thermal insulation performance of the cabinet 52 of the refrigerator 50, reducing the energy efficiency of the refrigerator 50.

The insulation 10 may be used in any suitable location of the refrigerator 50 where insulation is desired. In some embodiments, the enclosure 54 includes side panels 60 and a back panel 62, and the thermal shield 10 is positioned between the side panels 60 and/or the back panel 62 and the inner bladder 56. In this way, the heat insulator 10 can contribute to improving the heat insulating performance of the side and/or rear surface of the box 52, and can contribute to the structural mechanical strength of the side and/or rear surface of the box 52.

The insulation 10 may be arranged with the side panels 60 and/or the back panel 62 in any suitable manner. In some embodiments, the insulation 10 is against the side panels 60 and/or the back panel 62. In this way, the heat insulator 10 can contribute to improving the heat insulating performance of the side and/or rear surface of the box 52, and can contribute to the structural mechanical strength of the side and/or rear surface of the box 52.

In some embodiments, an adhesive such as hot melt adhesive, AB adhesive, double-sided adhesive, or other glue can be applied to one side of the thermal insulation member 10, and then the thermal insulation member 10 can be adhered to the corresponding position of the side panel 60 and/or the back panel 62 of the refrigerator 50.

The shape, configuration, and size of the insulation 10 can be adjusted as desired. In some embodiments, insulation 10 corresponds in size to box 52. With a large box 52, the size of the insulation 10 can be larger and vice versa.

The insulating material 58 may be made in any of a variety of suitable ways. In some embodiments, the insulating material 58 is foamed from a foam material. The thermal insulation material 58 foamed by the foaming material can contribute to lighter weight, lower cost and better thermal insulation performance of the refrigerator 50. The thermal insulation member 10 has a good strength, and after foaming of the foaming material, the refrigerator body 52, such as the side panel 60 and/or the back panel 62, of the refrigerator 50 is not easy to have obvious shrinkage marks corresponding to the position of the thermal insulation member 10, which can be beneficial to ensure the flatness of the refrigerator body 52, such as the side panel 60 and/or the back panel 62, of the refrigerator 50.

The various embodiments described above and shown in the drawings are illustrative of the invention and are not exhaustive of the invention. Any modification of the present invention by a person of ordinary skill in the related art within the scope of the basic technical idea of the present invention is within the scope of the present invention.

Where the technical conditions warrant, the subject matter of any independent claim herein may be combined with any single subject matter or combination of subject matter recited in any dependent claim to form new claimed subject matter.
