The partition plate can partition the box into a first accommodating space for accommodating the refrigerator 200 and a second accommodating space for accommodating goods. In this way, the heat generated during the operation of the refrigerator 200 will not affect the temperature in the second accommodating space.

In the illustrated embodiment, the refrigerator 200 is fixedly mounted to the partition plate using connections such as bolts, although it can of course be pinned or welded to the partition plate.

Further, the number and position of the discharge grids 203 are determined according to the action range of the electric field, so as to ensure that all spaces inside the box body 100 of the refrigerated container are within the action range of the electric field.

The electric field generating device can generate an electric field inside the box body 100. When the electric field generator 201 is turned on, the discharge net 203 generates an electric field. Under the action of the electric field, the goods located inside the box body 100 can be kept fresh, especially those located in the second accommodating space. The goods are kept fresh. Further, in order to improve the fresh-keeping performance, a discharge net can be arranged in the side plate, and the area of the discharge net can cover most of the side plate. A plurality of discharge grids can also be arranged in the same side plate, and the plurality of discharge grids can be connected in series. Therefore, the preservation period of the refrigerated food inside the box 100 can be prolonged, the damage to the food caused by freezing can be reduced, the quality and freshness of the food can be maintained, and the growth of microorganisms can be inhibited. By generating a spatial electrostatic field, it resonates with the water molecules in the food, activates the cells and water molecules of the food, improves the thermal conductivity of the frozen food, and improves the freezing/thawing speed of the food.
