7, straightening plates 18, 18 in the duct and upper discharge duct 3B
Thus, a lower discharge passage 22 communicating with the lower discharge port 21 is formed.

With the above configuration, the amount of cool air flowing out of the upper discharge port 19 can be reduced, and the amount of cool air flowing out of the lower discharge port 21 can be increased. An air curtain is formed from the upper discharge port 19. To minimize the intrusion of outside air,
The cool air from the lower discharge port 21 can cool the cooled object 10 flowing on the conveyor section 5 or the cooled object 10 stored in the storage space 9.

Further, as shown in FIG. 6, the cool air discharge section 11 is slidable in the vertical direction, so that when the cooling object 10 is cooled on the conveyor section 5 while performing any work, the cool air discharge section 11 is required. Slide the part 11 upward,

When the number of objects to be cooled 10 to be further worked is small, the right low-temperature conveyor device 1A is used as a work table, and the central low-temperature conveyor device 1B is used for cooling. Then, the supply of cold air to the low-temperature conveyor device 1C on the left side is stopped to cool the low-temperature conveyor devices 1A, 1C.
Since cool air can be sent only to B, an energy saving effect is achieved.

The flow of cold air with the above configuration will be described.

First, as shown by a white arrow in FIG. 4, air from a blower (not shown) is sent to the lower discharge duct 3A of the discharge duct 3. Then, it passes through the openings 14, 14,... Provided in the partition plate 13, and passes through the upper discharge duct 3B.
Sent to

The openings 14 become gradually larger from the near side to the far side of the blower. That is, the opening 14 is formed small on the near side where the flow rate of the cool air is fast, and on the back side where the flow rate of the cool air is slow.
Is formed to make the cool air sent to each upper discharge duct 3B uniform.

Then, as shown by oblique arrows in FIG. 5, a part of the cool air introduced into the upper discharge duct 3B first strikes the wind direction plates 15A, 15A and is discharged from the intermediate discharge ports 15, 15. The other cool air is sent to the cool air discharge unit 11, and the upper discharge passage 20 and the lower discharge passage 2
2 respectively. Here, when the work to be cooled 10 is placed on the conveyor unit 5 and the work is performed, the cold air discharge unit 11 is pulled up and slid upward. As shown by the white arrow in FIG. 1, the cool air sent to the upper discharge passage 20 is smaller than the cool air sent to the lower discharge passage 22, and is discharged from the upper discharge port 19 as an air curtain. Further, the cool air discharged from the lower discharge port 21 is located below the air curtain from the upper discharge port 19, and the intermediate discharge port 15,
15 together with the cold air from the
It is sprayed in the direction.

Thereafter, the cool air that has exchanged heat with the object to be cooled 10 flows down between the rollers 8 of the conveyor section 5 and is sucked through the suction port of the suction duct 4.

When the conveyer section 5 is pulled up and the object to be cooled 10 is stored in the storage space 9 as shown in FIG. 2, the cool air discharge section 11 is lowered and slid downward. It has become.

Then, the cool air follows the same route as described above and exchanges heat with the object to be cooled 10 stored in the storage space 9 and then is sucked through the suction port of the suction duct 4.

[0032]

As described above in detail, according to the first aspect of the present invention, the position of the cool air discharge can be changed by allowing the cool air discharge portion to slide vertically with respect to the upper discharge duct. Therefore, the object to be cooled from the object to be cooled on the conveyor to the object to be cooled in the storage space formed below the conveyor can be efficiently cooled.

According to the second aspect of the present invention, the cool air from the upper discharge port is used as an air curtain, and the cool air from the lower discharge port is used for cooling, thereby preventing outside air from entering as much as possible.

As described above, by forming the air curtain, the outflow of cool air for cooling the object to be cooled can be prevented as much as possible.

According to the third aspect of the present invention, since the upper discharge duct and the lower discharge duct extending in the longitudinal direction are provided with the partition plate having the opening for adjusting the flow rate of the cool air,
Cold air can be blown uniformly.
