Here, the thickness is the thickness of each layer in fig. 3, and fig. 3 is a structural view of a cross section of the vacuum thermal insulator 100 shown in fig. 1 and 2, that is, the thickness of each layer in the cross sectional direction of the vacuum thermal insulator 100, which is a dimension in the height direction.

Preferably, the thickness of the first gas barrier structure layer 11 and the thickness of the second gas barrier structure layer 13 are the same, for example, both may be 1mm or 1.1mm, so that the core material layer 12 may be coated from both sides of the core material layer 12.

In an alternative embodiment, the thickness of the core material layer 12 is 1.5-2.5mm, where the thickness of the core material layer 12 may be 1.8mm or 2mm, and the core material layer is in the shape of a net core material, so that the thickness of the whole vacuum heat insulator 100 can be controlled, and the thickness of the whole vacuum heat insulator 100 is suitable, so that the whole vacuum heat insulator 100 is not too thick, and the working space inside the household appliance is not occupied, and the heat insulation performance of the household appliance is not affected by too thin thickness.

Of course, the second gas barrier structure layer 13 may also include a multi-layer structure, which may be the same as the specific structure of the first gas barrier structure layer 11, and will not be described in detail herein.

As can be seen from fig. 5, the irregular-shaped structure plate 14 of the household appliance is a flat plate, in this case, the vacuum heat insulator 100 has a continuous Z-shaped structure, and the vacuum heat insulator 100 also has a sandwich-structured plate shape, and is disposed on the surface of the irregular-shaped structure plate 14 to wrap the irregular-shaped structure plate 14.
