Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a box that can be transported by a forklift, and to a box that can keep the inside of the refrigerator cool when it is stationary and transported.

[0002]

[Prior art]

 Stationary refrigerators used for storing fresh foods such as fresh fish and chemicals in a low temperature environment are well known. Also, a refrigerating vehicle having a sealed bed for keeping these items cold and transporting them is well known.

[0003]

[Problems to be solved by the device]

 For items that need to be transported in a cold state, such as fresh fish, remove the items from the refrigerator installed at the transport source, load them on the bed of the cold storage vehicle, transport them to the destination with the cold storage vehicle, and then install them at the transport destination. It is necessary to move the refrigerator from the cargo carrier of the refrigerated vehicle to the refrigerator again. It takes time and effort to transfer goods during such transportation, and since the fixed refrigerator and the cargo bed of the cold storage vehicle do not have the same volume and size, they can be transferred to one cold storage vehicle. There is also a problem that management of each item to be transported becomes troublesome, such as when a plurality of items to be transported are collectively loaded. In addition, when the goods are transferred between the refrigerator and the cold storage car, the cold storage condition cannot be maintained, which may deteriorate the quality of the goods. However, there was a problem of increasing the running cost of the refrigerator.

In view of the above problems, an object of the present invention is to make it possible to easily and efficiently carry and manage the storage and storage of articles that are stored and transported in a cold state.

[0005]

[Means for Solving the Problems]

 In this invention, a box 1 that can be transported by a forklift has a heat insulating structure, and a refrigerator 13 is attached to the box 1, and the refrigerator 13 can be operated by a commercial AC and a battery or a commercial AC and an AC power source of a vehicle-mounted generator. The above issues are solved by making it possible.

That is, the box with a refrigerating device of the present invention is provided with a space 3 below the floor surface 2 of the box 1 into which a fork of a forklift is inserted, and the floor surface 2, the ceiling surface 5, the wall surface 6 and the door panel 7 are provided. It is provided with a refrigerator 13 which is formed of a heat insulating wall and which is operated by commercial alternating current for cooling the inside of this box. The refrigerator 13 is provided with a DC / AC converter 18 and / or an AC / AC converter 29 for converting its output to a commercial AC, and a plug 16 for connecting this refrigerator to a commercial AC power supply.

[0007]

[Action]

 When the box of the present invention is used in a stationary state, the plug 16 is inserted into the outlet of the commercial AC power supply provided in the warehouse and the refrigerator 13 is operated to keep the inside of the box 1 at a low temperature. When carrying the goods in the box, the plug 16 is removed, and the box is placed on the bed of the vehicle by a forklift and carried together with the box. Upon arrival at the destination, the box 1 is unloaded to the destination warehouse by a forklift, and the plug 16 is inserted into the outlet of the commercial power source arranged in the destination warehouse to operate the refrigerator 13. Cooling in the box 1 during transportation is performed by converting the current from the battery 21 mounted on the vehicle or in the box into the alternating current by the DC / AC converter 18 to drive the refrigerator 13 or the power generation installed in the vehicle. The AC current generated by the machine is converted into commercial AC by the AC converter 29 to operate the refrigerator 13.

According to such a transportation method, the operation of the refrigerator 13 is stopped only when the box is loaded / unloaded to / from the vehicle, and the loading / unloading work involves storing the articles in a box in a sealed state. As it is carried out by the forklift promptly, there is no change in the temperature inside the refrigerator. In addition, since each box is maintained at a preset temperature according to its contents both during stationary and during operation, the cold storage temperature may change during storage and during transportation. Nonetheless, the independence of the cold insulation temperature of each box is maintained even when multiple containers are transported by one vehicle. In addition, when a DC exchange converter is provided and the battery is installed in the box 1, the operation of the refrigerator 13 is not interrupted even when the box is loaded and unloaded on the vehicle, and the internal temperature of the refrigerator can be improved. Can be maintained accurately.

【Example】

 1 and 2 are views showing a first embodiment of the present invention. The box 1 is formed to have the same external dimensions as, for example, a conventionally used container box, and an underframe 4 having a space 3 under which a forklift claw is inserted is fixed under the floor 2. ing. The floor surface 2, ceiling surface 5, wall surface 6 and door panel 7 of the box have a structure in which a heat insulating material 9 is sandwiched between iron plates 8 of the ginkgo, and a compressor 12 driven by an AC motor 11 is provided. The heat absorber 14 of the refrigerator 13 is arranged inside the box, and the radiator 15 is arranged outside the box. From the AC motor 11 for driving the refrigerator, a cable 17 connected to a plug 16 inserted into an outlet of a commercial power source and a cable 19 connected to an output side of a DC / AC converter 18 are connected in parallel. The DC-AC converter of the illustrated embodiment has a structure including a generator 23 driven by a DC motor 22 1 driven by a battery 21, and the output terminal of the generator 23 is connected to a cable 19 1. The battery 21 is mounted together with the DC / AC converter 18 on a receiving stand 24 provided on the underframe 4 of the box.

Since FIG. 5 shows an AC / AC converter 29 used in place of the DC / AC converter 18, it is equipped with an AC generator 23 rotatably driven by an AC motor 28. Is connected to a plug 27 connected to the outlet of the on-vehicle generator. In this structure, the plug 27 is connected to the outlet of the vehicle-mounted generator to rotate the AC motor 28, the AC generator 23 generates commercial AC, and the refrigerator 13 is driven.

The above embodiment uses the DC / AC converter 18 or the AC / AC converter 29 composed of a motor and a generator. These converters are inverters and transformers using thyristors and the like. Of course, it is also possible to configure by combining and.

[Effect of device]

 According to the invention described above, storage and transportation of perishable foods and chemicals that need to be kept in a cold state and the management thereof are very easy, and not only can the number of steps during transportation be greatly reduced. The effect is that fluctuations in cold storage temperature during transportation can be avoided.
