For example, instantiating the drying of the core material 2 in manufacturing process and enclosure 4 at 100 DEG C in present embodiment 1
The case where being carried out by heat treatment in 2 hours down, but the temperature heated and time, as long as core material 2 can be removed
And temperature and the time of the moisture of enclosure 4, it's not limited to that.In addition, the drying of core material 2 and enclosure 4 is in benefit
Carried out in the state of having coated core material 2 with enclosure 4, but can also the drying for having carried out core material 2 and enclosure 4 respectively it
Afterwards, core material 2 is coated using enclosure 4.In addition, in the manufacturing process of Vacuumed insulation panel 1 involved in present embodiment 1,
Adsorbent 3 is configured between core material 2 and enclosure 4 after core material 2 and enclosure 4 are dry, but can also in core material 2 and
Adsorbent 3 is configured before enclosure 4 is dry.
Embodiment 2.
In present embodiment 2, to an example for having the hot box of Vacuumed insulation panel 1 involved in embodiment 1
It is illustrated.In addition, in present embodiment 2, it is identical as embodiment 1 in the project not described especially, for identical function
Energy, structure, are described using identical appended drawing reference.
Fig. 3 is the cross-sectional view for indicating the brief configuration of hot box involved in the embodiments of the present invention 2.Hot box
100 such as using in the refrigerator for requiring high heat-proof quality.
As shown in figure 3, hot box 100 has the interior case 110 of outer container 120 with the inside for being configured at the outer container 120.Moreover,
Configured with the Vacuumed insulation panel 1 illustrated in the embodiment 1 between interior case 110 and outer container 120, in interior case 110 and outer container 120
Between be thermally shielded.
For the position that Vacuumed insulation panel 1 configures, as long as the position that can be thermally shielded between interior case 110 and outer container 120
It sets, is just not particularly limited.For example, it is also possible to which Vacuumed insulation panel 1 is configured to and the face opposed with outer container 120 in interior case 110
Contact.In addition, for example, it is also possible to Vacuumed insulation panel 1 is configured to and the face contact opposed with interior case 110 in outer container 120.Separately
Outside, for example, it is also possible to which spacer etc. is arranged between interior case 110 or outer container 120 and Vacuumed insulation panel 1, and make interior case 110 and
