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 truck or other transport vehicle.

[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, mounted on a transport vehicle from this 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.

The structure of such a cool box will be described with reference to FIG. That is, the cool box 1 has a vertically rectangular cool box body 2 and a machine room 3 installed outside the lower rear portion of the cool box body 2. It consists of. In the machine room 3, a condenser 4, a condenser fan 5, a compressor 6, and the like, which are components of a cooling device, are installed. The evaporator 7 and the evaporator fan 8 are installed, and the air cooled by the evaporator 7 is circulated in the refrigerator by the evaporator fan 8, so that the cool storage body 2
The inside is kept cool.

[0004]

When the cool box 1 constructed as described above is loaded on a transport vehicle, the fork 9a of the forklift 9 is moved to the cool box body 2 and the machine room as shown in FIG. 3 and lift it into a transport vehicle.

However, the fork 9a often collides with the machine room 3 when loading the cool box 1, whereby the machine room 3 is deformed,
There is a problem that the compressor 6 and the like installed in the machine room 3 are damaged.

In order to solve such problems, it has been proposed to provide a machine room 3 in which the compressor 6 and the like are installed above the ceiling wall of the cool box main body 2. For example, the upper portions of adjacent cold storage main bodies 2 often collide with each other, and also have a problem that the machine room 3 is deformed.

[0007] In view of the above-mentioned conventional problems, an object of the present invention is to provide:
The machine room is not damaged when loading the transport vehicle,
Another object of the present invention is to provide a cool box that can sufficiently withstand an impact during traveling.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a method for installing a compressor, a condenser, a fan for a condenser, etc., which are components of a cooling device, in a machine room. In a cool box in which an evaporator, which is also a component of the cooling device, is installed in the cool box body, a machine room is formed on the ceiling wall of the cool box body, and at least a part of the peripheral wall of the machine room is made of a strong material. It has a structure formed by high heat insulating walls.

According to the present invention, since the machine room is formed above the ceiling wall of the cool box body, the fork of the forklift may hit the machine room when the cool box is loaded on the transport vehicle by the forklift. Absent. Further, since the peripheral wall of the machine room is formed of a high-strength heat insulating wall, it can sufficiently withstand an impact that occurs when the transport vehicle travels.

[0010]

1 to 3 show an embodiment of a cool box according to the present invention. FIG. 1 is a sectional view of the cool box.
FIG. 2 is a plan view of a machine room, and FIG. 3 is a cross-sectional view showing a structure of a heat insulating wall.

First, a schematic configuration of a cool box according to the present embodiment will be described with reference to FIG. The cool box 10 is movable and has a vertically long box-shaped cool box main body 11, and is formed of a heat insulating material so that articles stored in the cool box main body 11 are not affected by the outside air temperature. . A machine room 12 is installed on the ceiling wall 11a of the cool box main body 11, and a compressor 13, a condenser 14, a condenser fan 15, an electrical box 16, a battery 17, and the like are installed in the machine room 12. On the other hand, the cold storage agent 18
The evaporator 19 and the evaporator fan 20 provided with are installed, and these devices 13 to 20 constitute a cooling device.

The machine room 12 in which the cooling device is installed as described above.
In the peripheral wall 121, a front wall 121a is an iron-based air intake panel that takes in outside air, and other parts
(Back wall and both side walls) 121b is constituted by a heat insulating wall. Here, as shown in FIG. 3, the heat insulating walls of the cool box main body 11 and the machine room 12 are formed of a foamed resin A such as hard urethane foam between an iron-based inner plate A1 and an iron-based outer plate A2.
3 and has a high strength.

When the inside of the cool box main body 11 is cooled by the cooling device, each device 13 to 13 except for the evaporator fan 20 is used.
1, the outside air is sucked from the air suction panel of the front wall 121a as shown by the two-dot chain line arrow in FIG. 1 and is passed through the condenser 14 for heat exchange. Heat exchange is performed with the cold storage agent 18 to exchange heat with the cold storage agent 18. When the cold storage is completed, only the evaporator fan 20 is operated, and the cool heat of the cold storage agent 18 is introduced into the cold storage main body 11 through the duct 21 in the cold storage main body 11 as shown by the one-dot chain line arrow in FIG. It is circulated, and the inside of the cool box 11 is cooled to a predetermined temperature by a temperature sensor or the like (not shown). When the cold storage in the cool box main body 11 is completed, the front door 22 is opened to store articles such as fresh food products in the cool box main body 11, and the cool box 10 is loaded on a transport vehicle. to deliver.

As described above, the cool box 10 according to the present embodiment.
Since the machine room 12 is installed on the ceiling wall 11a of the cool box main body 11, the fork of the forklift does not hit the machine room 12 when loading the cool box 10 into a transport vehicle. Since the peripheral wall 121 is formed of a heat insulating wall having high strength, the peripheral wall 121 can sufficiently withstand an impact generated when the transport vehicle travels.

Although the front wall 121a is formed of a single panel made of an iron-based material in the above embodiment, it may be formed of a heat insulating wall having the above structure.

[0016]

As described above, according to the present invention, the machine room is formed above the ceiling wall of the cool box main body. The fork does not hit the machine room, and the peripheral wall of the machine room is formed of a high-strength heat-insulating wall, so that it can sufficiently withstand the impact that occurs when the transport vehicle travels.
