[0025] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the embodiments of the present invention, some technical features well known in the art are not described.

[0026] In order to fully understand the embodiments of the present invention, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other embodiments.

[0027] like Figure 1 and Figure 2 As shown, in order to improve the fresh-keeping performance of the goods inside the box of the refrigerated container, the present invention provides a refrigerated container 1. The refrigerated container 1 includes a box 10, a refrigerator 20 fixed to the box 10, and an electric field generating device fixed to the box 10. The refrigerator 20 can reduce the temperature inside the box 10 after being powered on, and the electric field generating device can generate an electric field inside the box 10 after being powered on. Figure 1-Figure 7 , a refrigerated container 1 according to the present invention is described in detail.

[0028] like Figure 1 As shown, the box body 10 may include a bottom plate 13, a top plate 12, a front plate 14, a rear plate 15, and two side plates 11. In order to further improve the heat preservation performance of the box body 10, the box body plates of the box body 10 may be made of heat preservation materials. Figure 4 and Figure 5 As shown, in the illustrated embodiment, the box body 10 includes an inner box body plate 111 , an outer box body plate 113 , and a heat-insulating layer 114 disposed between the inner box body plate 111 and the outer box body plate 113 .

[0029] The refrigerator 20, as a cold source of the refrigerated container 1, can be fixed to the box plate of the box body 10. When the refrigerator 20 is powered on, the refrigerator 20 can release cold air into the inside of the box body 10. Optionally, the refrigerator 20 can be fixed to the outside of the box plate of the box body 10. Figure 2As shown, in the illustrated embodiment, the refrigerator 20 is fixedly mounted on the outer side of the front plate 14 by a connector such as a bolt, and can also be pinned or welded to the box body plate. It should be noted that the cold source of the refrigerated container 1 according to the present invention is limited to the refrigerator 20, and other suitable refrigeration devices can also be used in the refrigerated container 1.

[0030] like Figure 3 As shown, the electric field generating device includes an electric field generator 30 and at least one electrode plate 31 (for example, 1, 2, or 4). The electric field generator 30 is fixed to the box 10. The electrode plate 31 is arranged inside the box 10. The electric field generator 30 is electrically connected to the electrode plate 31. For example, in the illustrated embodiment, the electric field generator 30 is connected to the electrode plate 31 through a wire 32. Among them, when the electric field generator 30 is powered on, the electric field generator 30 can convert a low voltage into a high voltage and transmit it to the electrode plate 31, so that the electrode plate 31 generates an electric field, thereby being able to keep the goods located inside the box 10 fresh.

[0031] Optionally, the electric field generator 30 is an alternating electric field generator, which can control the electrode plates 31 to generate an alternating electric field inside the box 10. Further, the number and position of the electrode plates 31 are determined according to the range of action of the electric field, so as to ensure that all spaces inside the box 10 of the refrigerated container 1 are within the range of action of the electric field.

[0032] According to the refrigerated container 1 provided by the present invention, it is provided with a refrigerator 20 for reducing the temperature inside the box body 10, and an electric field generating device capable of generating an electric field inside the box body 10. The electric field generating device after being energized can generate an electric field inside the box body, and under the action of the electric field, the shelf life of the refrigerated food inside the box body 10 can be extended, the damage to the food caused by freezing can be reduced, the quality and freshness of the food can be maintained, the growth of microorganisms can be inhibited, and corruption can be reduced.

[0033] By setting the refrigerator 20 and adjusting the intensity of the cold source delivered to the refrigerated container 1, the temperature inside the box 10 of the refrigerated container 1 can be adjusted. Further, under the action of the electric field, the refrigerated container 1 according to the present invention can have three working states of different temperature environments: a refrigerated working state of 4°C to 0°C, a supercooled refrigerated working state of 0°C to -5°C, and a frozen working state of -5°C to -18°C. By forming working states of different temperature environments, the refrigerated container 1 can adapt to the refrigeration needs of different foods such as fruits, vegetables, fish, meat, etc., and reduce the damage of low temperature to food as much as possible.

[0034] Specifically, when the refrigerator 20 and the electric field generating device of the refrigerated container 1 according to the present invention are powered on, the refrigerator 20 releases cold air inside the box 10, and the electric field generating device generates an electric field. When the inside of the box of the refrigerated container 1 is in the refrigerated temperature range of 4°C to 0°C, the electric field acting in the box can extend the shelf life of food, reduce food spoilage, and improve the retention time of the appearance quality of food; when the inside of the box of the refrigerated container 1 is in the supercooled refrigerated temperature range of 0°C to -5°C, the electric field acting in the box can achieve fish, meat, milk, etc. Not frozen, can extend the shelf life of food, and improve the retention time of the appearance quality of food; when the inside of the box of the refrigerated container 1 is in the freezing temperature range of -5°C to -18°C, the electric field acting in the box can reduce the tissue damage of freezing to food, extend the shelf life of food, and maximize the quality and freshness of food after thawing.

[0035] Optionally, the outer side of the box body 10 has a receiving space for receiving the electric field generator 30, and the electric field generator 30 is fixed in the receiving space on the outer side of the box body 10. Figure 2 As shown, in the illustrated embodiment, the refrigerator 20 is arranged outside the front end plate 14 of the box 10, and the electric field generator 30 is fixed to the cable trough located below the refrigerator 20. Further, the electric field generator 30 can be connected to the power supply of the refrigerator 20, thereby providing power for the electric field generator 30. By arranging the electric field generator 30 outside the box 10, its dry environment and suitable temperature can increase the service life of the electric field generator 30, and can save the storage space inside the box 10.

[0036] Further optionally, if Figure 3 As shown, the refrigerator 20 has a through hole 21. The electric field generator 30 on the outside of the box 10 and the electrode plate 31 on the inside of the box 10 can be electrically connected through the through hole 21. It should be noted that the electric field generator 30 and the refrigerator 20 can be fixed at one or more of the six box plates of the box 10. For example, Figure 2 As shown, in one embodiment of the present invention, the electric field generator 30 and the refrigerator 20 can be fixed together at the front end plate 14, while in an embodiment not shown, the electric field generator 30 can be fixed to the front end plate 14 and the refrigerator 20 can be fixed to the rear end plate 15.

[0037] like Figure 4 and Figure 5As shown, in the illustrated embodiment, the electrode plate 31 is fixed to the inner box plate 111 of the side plate 11 of the box body 10. Specifically, the inner box body plate 111 is formed with an electrode plate mounting groove 112 opening toward the inside of the box body 10. The electrode plate 31 is installed in the electrode plate mounting groove 112. Optionally, the adjacently arranged electrode plates 31 can be arranged in the same electrode plate mounting groove 112 at intervals, or can be arranged in different electrode plate mounting grooves 112. Thus, by providing the electrode plate mounting groove 112, it can be ensured that the electrode plate 31 does not protrude from the inner box plate 111 after installation, so as to maintain the original internal storage width of the box body 10 of the refrigerated container 1. It should be noted that the electrode plate 31 can also be fixed to other positions inside the box body 10. For example, in one embodiment of the present invention, the electrode plate 31 is fixed to the top plate 12 of the box body 10.

[0038] According to the refrigerated container 1 of the present invention, the electrode plate 31 can be connected to the box body 10 in an insulated manner. Figure 5 As shown, an insulating member such as an insulating pad 33 may be provided between the electrode plate 31 and the box body 10. Figure 5 As shown, an insulating pad 33 may be provided in the electrode plate mounting groove 112. The electrode plate 31 is connected to the insulating pad 33 by a first fastener 35 such as a bolt, and the insulating pad 33 is connected to the box body 10 by a second fastener 36 such as a screw, wherein the first fastener 35 is spaced apart from the second fastener 36. Thus, the electricity on the electrode plate 31 will not be conducted to the box body 10, thereby avoiding the risk of leakage of the box body 10 and avoiding the influence on the electric field inside the box body 10. Optionally, in order to further avoid leakage of the box body 10, the inner box body plate of the refrigerated container 1 can be set to be insulated from the ground, for example, the insulation resistance is not greater than 1 ohm.

[0039] like Figure 6 and Figure 7 As shown, in the illustrated embodiment, the electric field generator 30 is connected to the electrode plate 31 through a wire 32. The electric field generating device also includes a conduit 34, and the wire 32 extends through the conduit 34. The conduit 34 can be made of an insulating material. Specifically, in the illustrated embodiment, the conduit 34 is configured to connect two adjacent electrode plate mounting grooves 112 in the box body 10, and the wire 32 passes through the conduit 34 to connect the electrode plate 31 set in the electrode plate mounting groove 112. By providing the conduit 34, it is possible to protect the wire 32 and avoid the risk of leakage of the wire 32. Optionally, the conduit 34 can be provided in an insulation layer 114 such as a side panel 11. Thereby, the impact on the internal storage space of the box body 10 can be reduced.

[0040] Optionally, the electrode plates 31 can be connected in series or in parallel with each other and connected to the electric field generator 30, or can be connected to the electric field generator 30 individually to form a closed current loop. Further optionally, the electrode plates 31 located on the same side wall of the box body 10 are connected in series. The electrode plate 31 located on one side wall is connected in parallel with the electrode plate 31 located on the other side wall. Figure 6 As shown, in the illustrated embodiment, three electrode plates 31 are symmetrically arranged on the two side plates 11 of the refrigerated container 1. The three electrode plates 31 located on the same inner box plate 111 are connected in series through wires 32, and the three electrode plates 31 located on the inner box plates 111 on different sides are connected in parallel as a whole. In this way, the number of wires 32 inside the box 10 can be reduced, and the arrangement of the wires 32 can be simplified. It should be noted that the setting position of the electrode plate 31 in the box 10 is not limited to the embodiment shown, and it can be set at any suitable position inside the box 10 according to actual needs.
