Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling container used for home delivery services and the like.

[0002]

2. Description of the Related Art Conventionally, as this type of cooling container, the one described in Japanese Patent Laid-Open No. 2000-186879 is known.

In this cooling container, a ceiling wall of a container body for accommodating articles is detachably provided, and a cooling device for cooling the interior of the container is installed on the ceiling wall, and a compressor is provided on an upper surface of the ceiling wall. While the condenser fan and the condenser are installed, the evaporator and the internal circulation fan are installed on the lower surface of the ceiling wall.

In this cooling container, when the cooling device is repaired, the cooling device can be removed from the container body by simply removing the ceiling wall, and the cooling device can be easily repaired. If a spare ceiling wall with a cooling device is attached to the container body, the container body can be used continuously, and efficient use of the cooling container is realized.

Further, even when one of the cooling device and the container body has reached the end of its life, it is sufficient to replace one of them, so that the long life of the entire cooling container is realized.

[0006]

However, in the cooling container, since the ceiling wall of the container main body is a flat plate, the evaporator and the circulation fan inside the container largely protrude to the inside of the container main body to store the article storage space. Had a problem of narrowing.

Further, when carrying articles in a cooling container, a plurality of cooling containers may be loaded on a loading platform such as a truck, so that the heat exhausted from the side surface of the cooling container on the loading platform. It is difficult to take space. On the other hand, since the ceiling wall is flat as described above, the air blown by the condenser fan is horizontal, that is, the side surface of the cooling container. There was a risk of causing.

In view of the above-mentioned conventional problems, an object of the present invention is to provide a cooling container that does not narrow the article storage space in the container body and does not cause defective heat discharge.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention according to claim 1 provides a ceiling wall of a container body for accommodating articles in a detachable manner for cooling the interior of the warehouse. In a cooling container equipped with a cooling device, the rear part is bulged upward from approximately the center in the front-rear direction of the ceiling wall to form a box body with an opening on the lower surface. It has a structure with an internal circulation fan and an evaporator installed.

According to the first aspect of the present invention, since the internal circulation fan and the evaporator, which are the indoor components of the cooling device, are installed in the box body, the indoor components are prevented from protruding into the container body. As a result, the space for storing the goods in the container body becomes wider.

According to a second aspect of the present invention, in the cooling container according to the first aspect, a condenser fan, a condenser and a compressor, which are components of a cooling device, are provided on the ceiling wall from the front side of the ceiling wall toward the center. The machine has been installed and the front wall of the box has a structure that extends obliquely upward toward the rear. According to the invention of claim 2, the air blown by the condenser fan is smoothly guided upward through the front wall of the box.

1 to 5 show an embodiment of a cooling container according to the present invention. FIG. 1 is a side sectional view of the cooling container, and FIG. 2 is a front sectional view of the cooling container. 3 is an assembled perspective view showing the connecting structure of the ceiling wall and the peripheral side wall, FIG. 4 is an assembled perspective view showing the connecting structure of the front upper wall and the installation plate, and FIG. 5 is a state in which the ceiling wall is removed from the container body. FIG.

As shown in FIGS. 1 to 3, the cooling container 1 has a container main body 2 having a heat insulating wall structure and a rectangular parallelepiped outer shape. The container body 2 has peripheral side walls 21 having front and upper openings, the front opening is opened and closed by a door wall 22, and the upper opening is removably closed by a ceiling wall 23. A front upper wall 24 is fixed to the upper front surface of the upper surface of the peripheral side wall 21.

In the container body 2 thus constructed, the ceiling wall 23 is constructed as follows. That is,
The ceiling wall 23 has a horizontal wall 23 from the front side to the front and rear substantially in the center.
In addition, a box body 232 is formed which is bulged upward from the approximate center in the front-rear direction of the ceiling wall 23 and has an open lower surface.

An installation plate 233 for equipment installation is fixed to the upper surface of the horizontal wall 231 so as to project forward. On the upper surface of this installation plate 233, the condenser 31, which is an outdoor component of the cooling device 3, is installed from the front. , A condenser fan 32 and a compressor 33 are sequentially installed. Inside the box body 232, an internal circulation fan 34 and an evaporator 35, which are indoor components of the cooling device 3, are installed. Also, the box body 232
The front wall 232a extends obliquely upward toward the rear.

The structure for attaching and detaching the ceiling wall 23 is constructed as shown in FIGS. That is, as shown in FIG. 3, stepped portions 211 and 234 are provided at the upper end of the peripheral side wall 21 and the lower end of the ceiling wall 23 so as to be mutually offset.
234 are superposed, and are attached and detachably connected with screws 26 using L-shaped attachment fittings 25.
Further, as shown in FIG. 4, the front end of the horizontal wall 231 of the ceiling wall 23 and the rear end of the front upper wall 24 have stepped portions 235 and 241 which are also cut out from each other.
241 are vertically stacked, and the installation plate 233 and the front upper wall 24 are connected by screws 27 so as to be attachable and detachable.

According to the cooling container 1 of this embodiment, the internal circulation fan 34 and the evaporator 35, which are indoor components, are housed in the box body 232 which is bulged upward.
As a result, the article storage space in the container body 2 becomes wider.

As shown by the solid arrow in FIG. 1, the air blown by the condenser fan 32 flows rearward through the condenser 31 and further around the compressor 33. The exchanged air is guided obliquely upward by the front wall 232a of the box body 232 and is smoothly discharged. here,
When the cooling container 1 is fully loaded on a loading platform such as a truck, there is almost no exhaust space on the side surface of the cooling container 1. On the other hand, a sufficient exhaust space is formed in the upper part of the cargo bed because no luggage can be placed above the cooling container 1. The cooling container 1 according to the present embodiment can reliably perform condensation exhaust heat by utilizing the space above the loading platform.

For maintenance of the cooling device 3, the screws 26 and 27 shown in FIGS. 3 and 4 are removed, and the cooling device 3 shown in FIG.
By raising the ceiling wall 23 upward as shown in FIG. 3, the cooling device 3 can be easily removed from the peripheral side wall 21 together with the ceiling wall 23.

[0020]

As described above, according to the first aspect of the invention, the internal circulation fan and the evaporator, which are the indoor components of the cooling device, have their rear portions upward from the approximate center in the front-rear direction of the ceiling wall. It is bulged toward and stored in a box body having an opening on the lower surface, which raises the installation position of the indoor component parts, so that the article storage space of the container body is correspondingly enlarged.

According to the second aspect of the present invention, even when the cooling container is fully loaded on the bed of a truck or the like, the air blown by the condenser fan is smoothly guided upward, and the exhaust heat failure does not occur.
