Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a mobile fresh food storage for keeping fresh foods at a low temperature for a long time and transporting them to long distances.

BACKGROUND ART Conventionally, in order to transport perishable foods over long distances, a method has been adopted in which perishable foods are loaded onto a refrigerated vehicle equipped with a refrigerating cycle.

However, in such refrigerator truck type refrigerators, the door of the refrigerator is opened and closed to load and unload food, etc., so warm air enters the refrigerator and the temperature inside the refrigerator rises rapidly, which has a negative impact on the food being transported. It was affecting me.

Therefore, recently, as shown in Figure 3, casters 1 are attached to the bottom of the refrigerator, and the evaporator of the refrigeration cycle is attached above the refrigerator, which is entirely covered with a heat insulating material 2, separated from the ceiling by a predetermined space. It is known that a cooling plate 4 is installed, and a cold storage tank 6 filled with a cold storage agent is placed above or below the cooling plate (Utility Model Publication No. 26071/1983).

In this type of product, the refrigeration cycle is operated to cool the refrigerant until just before it is placed on the transport vehicle, and after it is placed on the transport vehicle, the operation of the refrigeration cycle is stopped and the cold air stored in the refrigerant is released. Use to keep the inside of the refrigerator at a low temperature. When the delivery location is reached, only the refrigerator containing the food to be delivered is unloaded without having to open the doors of the remaining refrigerators, which has the advantage of preventing warm air from entering the food being transported. There is.

Problems that the invention aims to solve However, in this conventional system, a cold storage tank containing a cold storage agent is installed in the ceiling of the refrigerator, so even if a small amount of food is placed in the refrigerator, If a large amount is used, there is an inconvenience that the cold air may not be distributed evenly throughout the refrigerator.

Furthermore, if the refrigerator is installed only on the ceiling, the temperature of the panels inside the refrigerator will rise due to radiant heat from outside the refrigerator, causing the inconvenience that some parts of the refrigerator may become warm.

Furthermore, since the cooling plate is arranged directly in the storage, dew condensation water tends to adhere to the cooling plate, resulting in the inconvenience that water droplets fall onto the food.

SUMMARY OF THE INVENTION In view of the shortcomings of the prior art, it is an object of the present invention to provide a type of storage that can cool the inside of the refrigerator almost uniformly and that does not cause the temperature inside the refrigerator to rise easily due to external influences.

Means for Solving the Problems In other words, the present invention is a storage cabinet whose interior is sealed with a casing made of a heat insulating material and a door body made of a heat insulating material. A heat transfer panel is installed, the evaporator of the refrigeration cycle is placed in the space between the heat transfer panel and the heat insulating material, and a small bag filled with a cold storage agent is placed so as to sandwich the cooling pipe of the evaporator of the refrigeration cycle. This objective will be achieved by a mobile fresh storage facility.

Function In the storage according to the present invention, the refrigeration cycle is first operated until immediately before transportation. Then, since the evaporator of the refrigeration cycle cools the regenerator disposed around the cooling pipe, the regenerator is cooled, and the inside of the storage is cooled from multiple sides via the heat transfer panel.

After stopping the refrigeration cycle, the storage is placed on a transport vehicle and moved.

During movement, the cold air kept from the bag containing the cold storage agent is propagated into the storage via the heat transfer panel.

Furthermore, since the bags containing the cold storage agent are placed on multiple sides of the storage, the inside of the storage is cooled from multiple sides.

Furthermore, since many sides of the storage are covered with heat insulating materials, bags containing cold storage agents, and heat transfer panels, warm air from entering from outside is blocked by these members.

Embodiment Hereinafter, the present invention will be explained in detail according to an embodiment shown in FIGS. 1 and 2.

In the figure, 10 is a casing 1 made of a heat insulating material.
2 and a door body 14 made of a heat insulating material.

The back surface and both side surfaces of the storage 10 are divided into three rooms via heat transfer panels 20, 18, and 22 with a predetermined space in between.

In the space partitioned by the heat transfer panels 18, 20, and 22, three cooling pipes 26 distributed through a distributor 24 are evenly arranged so that the coolant flows from top to bottom.

In this embodiment, the cooling pipes 26 are arranged so that the intervals between the pipes gradually widen from the top to the bottom.

In the remaining space formed by the heat transfer panel, small bags 28 made of plastic bags containing an alcohol-based cold storage agent are evenly arranged.

Further, the pouch 28 containing the refrigerant is arranged to sandwich the cooling pipe 26 forming the evaporator of the refrigeration cycle, and prevents the cooling pipe from moving due to vibrations or the like.

A heat transfer panel 30 is installed on the ceiling of the storage 10 with a predetermined space in between.
20, 22, and the heat transfer panels 18,
20 and 22 is configured so that the cooling heat is transmitted to the heat transfer panel 30.

The space defined by the heat transfer panel 30 and the casing 12 is provided to block warm air from entering from the outside.

Casters 32 are provided below the storage 10 for easy movement.

34 is a compressor of the refrigeration cycle, 36 is a condenser, 38 is a capillary reach tube (expansion valve),
40 is a header, and 42 is an accumulator.

In the above-described configuration, in the storage according to this embodiment, when the refrigeration cycle is operated, the refrigerant that has passed through the capillary reach tube 38 is distributed in three directions via the distributor 24, and directed from the top to the bottom of the storage. It flows.

Then, the cooling pipe 26 connects to the small bag 2 in which the cold storage agent is injected.
8, and the pouch 28 cools each heat transfer panel 1.
8, 20, and 22, the inside of the storage 10 is gradually cooled via the heat transfer panel.

In addition, in the apparatus of this embodiment, since the cooling pipes 26, which are refrigerant pipes, are arranged so that the intervals gradually become wider from the top to the bottom, the upper part of the storage is cooled more than the lower part. It's summery.

This is because cold air generally flows from top to bottom, so the heat transfer panels 18, 20, 22
This is because the cooling efficiency is higher when the upper part is cooled.

After the cold storage agent has completed storing cold, the operation of the refrigeration cycle is stopped, and the device is then loaded onto a vehicle and transported to a predetermined location.

Since the refrigeration cycle is stopped during transportation, the temperature inside the storage chamber tends to rise rapidly due to the influence of outside air, etc., but small bags 28 containing a cold storage agent are placed on the back and both sides of the storage chamber 10. Due to this relationship, when the temperature is about to rise, the cold air from the cold storage agent is propagated into the storage via the heat transfer panel, so the temperature rise can be suppressed.

In this embodiment, heat transfer panels containing a cold storage agent are placed on three of the six walls inside the storage 10, the back and both sides, so the inside of the storage can be cooled almost evenly. .

Furthermore, the heat transfer panels 18, 2 on the back and both sides
Since the heat transfer panels 30 on the ceiling are connected to the panels 0 and 22, cooling from the ceiling can be expected due to the propagation of cold air.

Regarding the intrusion of warm air from the outside, all six sides of the storage room are covered with a casing 12 made of a heat insulating material, and heat transfer panels 18, 20 are installed on the four sides of the ceiling, back and both sides with a predetermined space between them. ,2
2 and 30 are installed, these serve as a buffer space to prevent intrusion.

In this embodiment, a pouch 28 in which a cold storage agent is injected is arranged on the circumferential surface of the cooling pipe 26.

This is the heat transfer panel 18, 20, 2 that covers the evaporator.
It is most preferable to inject the regenerator into the space formed in step 2, but in such a case, it becomes necessary to properly join the heat transfer panels so that there are no gaps, and the entire evaporator must be injected with the regenerator. It is possible to cover it with an injected bag, but in this case, there is a disadvantage that the cool storage agent accumulates below due to the action of gravity, and there is less cool storage agent above.

Effects As mentioned above, the storage according to the present invention has poor cooling efficiency in conventional storage because the cold storage agent is placed only in the ceiling, but the storage is improved by cooling from multiple sides. This configuration improves cooling efficiency.

In addition, since the storage chamber is configured to be cooled through a heat transfer panel even though a cold storage agent is placed on the side, it is possible to prevent condensed water from dripping, which has frequently occurred in the past.

Furthermore, the storage is covered with a heat insulating material and is configured to cover a heat transfer panel with a predetermined space in between, making it less susceptible to external influences than traditional storage, allowing you to store food for long periods of time. Can be transported.
