DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator for storing fresh foods, medicines and the like which need to be kept cool and transported by a transport vehicle such as a truck.

[0002]

2. Description of the Related Art Conventionally, when delivering goods such as fresh foods that need to be kept cool, goods from a client are once collected at a collection place, loaded on a transport vehicle from the collection place, and cooled while receiving the goods. A distribution system has been established to deliver the goods to a transportation vehicle. When the goods are to be mounted on a transportation vehicle, they are stored in a refrigerator beforehand, and the refrigerator is loaded on the transportation vehicle.

[0003] As a cooling structure of such a cool box, for example, one disclosed in Japanese Patent Application Laid-Open No. 1-306789 is known.

In this cool box, a cold storage agent, an evaporator for cooling the cold storage agent, and a cooling fan for circulating the cold stored in the cold storage agent in the main body are provided at the upper part of the cool box body. A machine room provided with a compressor, a condenser, and a fan for the condenser, and a battery room having a battery for supplying power to the cooling blower are provided below the cold storage main body.

[0005] When accumulating cold heat in the regenerator inside the cool box, power is supplied from an external power source to the compressor, the cooling fan, and the condenser fan to drive each device. Thereby, the cold air flows around the regenerator, and the regenerator is cooled. Then, when cold heat is accumulated in the cold storage agent, articles are stored in the cool box main body, and the articles are placed on a transport vehicle for delivery. During this delivery, the cooling fan is driven by the electric power of the battery, and the inside of the cool box main body is maintained at a desired temperature by the heat of fusion of the regenerator.

However, in this cool box, since the heat of fusion of the cold storage agent decreases with the lapse of the transportation time, a large amount of the cold storage agent must be filled in the cold storage body because of the necessity of long-term delivery. Therefore, there is a problem that the storage capacity of the articles is reduced accordingly. Further, since the weight of the regenerator increases, it is not preferable when the refrigerating agent is mounted on a vehicle having a limited weight. In addition, there is a problem that it is difficult to control the temperature in a system for keeping articles cool via the regenerator. .

[0007] Therefore, as a cold-retaining structure of the cold-storage main body, a compressor or the like of a refrigeration cycle is driven by a battery power source without using the cold storage agent, and the inside of the cold-reservoir main body is cooled by this refrigeration cycle during transportation. Has also been proposed.

[0008]

By the way, in the latter cold storage, when the power of this battery is consumed, the battery is carried to a place where the vehicle is to be charged or the charging operation is performed by lowering the cold storage from the vehicle. It is necessary to carry out charging work, or to prepare a large number of long cables and connect them to the cool box of the vehicle for charging.

However, according to the above-mentioned method, there is a problem that a large space is required in a collection and delivery center having a large number of vehicles, and it takes time to charge.

[0010] The object of the present invention is to solve the above-mentioned problems.
It is an object of the present invention to provide a cool box that allows a battery to be replaced and the battery can be attached and detached in a small space.

[0011]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a cold storage using a battery as a drive source of a cooling device for cooling an article in a cold storage main body. This battery is installed detachably.

According to the present invention, when power supply becomes necessary, it is sufficient to replace the battery with a pre-charged battery, and when charging the battery at night, it is possible to use the late-night power. it can. Furthermore, you may make it charge many batteries collectively.

Further , since the battery compartment is located at a lower position, a heavy battery can be easily replaced.
