[0027] The surfaces of the upper polyurethane foam plastic layer 7 and the lower polyurethane foam plastic layer 8 are both covered with a covering layer 9 .
[0028] It should be noted that the inner cavity of the box body 1 is divided into a fresh-keeping area 3 and a refrigerated area 4 by a partition plate 2. The fresh-keeping area 3 can be used to store fresh food, and the refrigerated area 4 can be used to store frozen food.

The upper polyurethane foam plastic layer 7 and the lower polyurethane foam plastic layer 8 have good thermal insulation performance, which can avoid heat exchange between the fresh-keeping area 3 and the refrigerated area 4 during use, thereby improving the accuracy of temperature control of the fresh-keeping area 3 and the refrigerated area 4. The inner cavity of the hollow glass layer 6 is a vacuum structure. There is a lack of heat transfer medium in the hollow glass layer 6, so that heat cannot pass through the hollow glass layer 6, thereby avoiding heat exchange between the fresh-keeping area 3 and the refrigerated area 4, thereby improving the accuracy of temperature control of the fresh-keeping area 3 and the refrigerated area 4. The hollow glass layer 6 is corrosion-resistant, aging-resistant and has a long service life.
[0029] In this embodiment, if Figure 4 and Figure 5 As shown, both ends of the partition plate 2 are integrally formed with limiting protrusions 10, and both ends of the partition plate 2 are plugged into the inner wall of the box body 1 through the limiting protrusions 10, the upper polyurethane foam plastic layer 7 is composed of an upper partition layer 11 and a lower partition layer 12, and the upper partition layer 11 is located above the lower partition layer 12, and the lower polyurethane foam plastic layer 8 is composed of an upper partition layer 11 and a lower partition layer 12, and the upper partition layer 11 is located above the lower partition layer 12, and reinforcing ribs 13 are provided between the upper partition layer 11 and the lower partition layer 12, and the reinforcing ribs 13 are in a cross structure, and the horizontal edges at both ends of the reinforcing ribs 13 extend out of the upper partition layer 11 and the lower partition layer 12, and the horizontal edges at both ends of the reinforcing ribs 13 are plugged into the inner cavity of the limiting protrusions 10.
[0030] It should be noted that the upper polyurethane foam plastic layer 7 and the lower polyurethane foam plastic layer 8 are both composed of an upper partition layer 11 and a lower partition layer 12. Reinforcing ribs 13 are provided between the upper partition layer 11 and the lower partition layer 12. The reinforcing ribs 13 are arranged in a staggered manner.
