Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION This invention relates to refrigerators, freezers, frozen containers and other fixed temperature storages for transporting fresh goods such as vegetables, flowers, seafood, etc., which prevents deterioration of fresh goods placed in the fixed temperature storage. It is a device that can be used for transport while transporting.

[0002]

2. Description of the Related Art For transporting fresh cargo such as vegetables, flowers, seafood, etc., the cargo is stored in trucks, ship refrigerators, freezers, frozen containers, etc. so that freshness can be maintained, and transported while maintaining a constant temperature. Is being done.

[0003]

[Problems to be Solved by the Invention] Perishable cargo such as vegetables, flowers, seafood, etc. generates waste gas while being stored in a storage such as a refrigerator and transported, and the phenomenon that freshness deteriorates due to this gas is generated. is there.

[0004]

[Means for solving the problem] The constant temperature storage of this invention is:
An oxygen cluster generator and a timer are provided to intermittently supply oxygen clusters obtained by passing air through a discharge tube to a constant temperature storage.

[0005]

[Function] Carbon dioxide, ethylene, and other wastes generated in the constant temperature storage during transportation of fresh cargo and accumulated in the storage are neutralized and rendered harmless by oxygen clusters, and accelerate the aging of fresh cargo. As a result, the freshness of the cargo during long-time transportation is reduced.

[0006]

1 shows a first embodiment of the present invention applied to a refrigerated truck.
An example will be described. A freezer 2 as a constant temperature storage is mounted on the vehicle body 1, and the inside thereof is maintained at a constant temperature by a refrigerator 3 driven by a dedicated engine. An oxygen cluster generator 4 is attached to the lower part of the vehicle body.

The oxygen cluster generator 4 generates oxygen clusters in which oxygen molecules are condensed by passing the air sucked through the filter 5 between the discharging electrodes of the oxygen cluster generator 6. Is
The air is sent into the freezer 2 through the feed duct 8 by the fan 7, and is replaced with air in the store discharged from the discharge duct 9.

In the freezer, gases such as carbon dioxide gas and ethylene gas discharged from fresh cargo, which accelerate the deterioration of freshness, gradually accumulate, and the freshness of fresh cargo gradually deteriorates due to these waste gases. The oxygen cluster sent into the freezer neutralizes these waste gases, so that the freshness of the cargo is prevented from deteriorating.

[0009] The operation of the oxygen cluster generator 4 is controlled by a timer (not shown) provided in the driver's seat, and a freezer stores a proper amount of oxygen clusters in a timely manner in accordance with the speed of accumulation of waste gas depending on the perishable cargo. To be sent to or,
Electric power for operating the oxygen cluster generator is supplied from a power supply provided in a truck or a power distribution facility provided in the vicinity of a container mounting portion in the case of a container.

[0010] In a constant-temperature storage box such as a container whose outer shape is box-shaped and the auxiliary equipment cannot be greatly protruded, a refrigerator is provided in a section provided by recessing a part of the container. The oxygen cluster generator can be provided by utilizing the above.

FIG. 2 shows a second embodiment of the present invention in which an oxygen cluster generator is provided at the upper corner of the constant temperature storage 2a.

A small section surrounded by a partition 10 is provided at the upper corner of the constant temperature storage 2a, and an evaporator 11, an electric fan 12, and an oxygen cluster generator 6 are installed therein.
Inside this small compartment, there are an outside air intake port 13 and an inside air intake port 1.
4, an appropriate amount of outside air and inside air is sucked in, cooled, and discharged from the cool air discharge port 15 into the inside of the refrigerator. A part of the cold air in the refrigerator is discharged from the outlet 16 and is replaced with the outside air entering from the outside air inlet 13. In this embodiment, the evaporator 1
1, only the fan 12 is provided in the partition 10, and other refrigerator components such as a compressor, a condenser and an engine are installed outside the storage.
It may be provided within 0. With this configuration, cold air containing oxygen clusters can be supplied into the constant temperature storage 2a.

[0013]

[Effects of the Invention] (1) Waste gas generated from fresh cargo is neutralized by oxygen clusters, so that the freshness of the cargo is hardly impaired.

(2) Therefore, it is possible to transport fresh cargo for a long time, and it is possible to extend the transport distance.
