Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box freezer most suitable for storage and transportation of frozen foods.

[0002]

2. Description of the Related Art Generally, as a refrigerator for indoor installation for home use or for business use, a compressor type refrigerator using a 100V household AC power supply (AC100V) is often used as a cooling energy source.

On the other hand, most of vehicle-mounted refrigerators installed in, for example, camper vans are so-called absorption refrigerators that use an aqueous ammonia solution, and a 100V household AC power supply and 12V are used as energy sources for cooling. Or 24V DC power supply (DC12V or DC24V)
And 3 types of LP gas are available.

This type of 3-way refrigerator does not use a compressor, so that it does not generate noise or vibration at all, and is lightweight and excellent in vibration resistance.

Here, the above-mentioned refrigerator is generally used for food storage, and not only has no mechanism for loading and unloading to / from a vehicle, but it is also taken into consideration when carrying it outdoors. No, it cannot be easily moved from this place once it is installed in place.

[0006]

As described above, in the conventional refrigerator, since the contents such as frozen food are not moved while being housed in the refrigerator, the refrigerator is a single carrier. Therefore, the present situation is that it cannot always be used for transporting frozen food or the like in a frozen state.

That is, for example, in the case of shipping frozen foods, the frozen foods to be shipped are loaded on a frozen truck whose entire carrier is a refrigerator, and when the frozen foods arrive at the site, the frozen foods are taken out from the refrigerator and delivered. , The supplier who received the goods puts this frozen food in his own refrigerator,
Further, when selling beer, canned juice, or the like in a place where power cannot be taken, such as outdoors, it is generally carried out to transport these items raw and soak them in ice water for sale.

In view of the above, the present invention can be used as a single carrier while containing frozen food and the like, and can be refrigerated at all times during the process of transportation and storage. The purpose is to provide what has been done.

[0009]

In order to achieve the above object, a box freezer according to the present invention adopts a three-way system in which a DC power source, an AC power source and LP gas are used as cooling energy sources, and is mounted on a vehicle. It is characterized by being equipped with a vehicle-mounting part to be used when doing so that it can be stacked up and down.

The waterproof type can also be used outdoors.

[0011]

According to the present invention configured as described above, for example, when shipping frozen foods, the frozen foods are housed in the box freezer, loaded into the vehicle as they are, and then transported to each supplier of the box freezer. However, the box freezer can be collected when it becomes empty, and in the course of this storage and transportation, the box freezer that needs refrigeration is always maintained by the AC power source for household use or the DC power source from the dynamo of the vehicle. Moreover, the box freezer can be cooled by operating the box freezer by LP gas while operating while individually adjusting the temperature to cool.

Moreover, by stacking the box freezer up and down during transportation and storage, the transport efficiency and the storage space can be reduced.
