Each 4 supports one shelf plate 18. Shelf 1
Although the support structure of 8 is arbitrary, for example, a structure in which a sleeve plate is hung between columns arranged in the depth direction, and the shelf plate 18 is supported by a pair of left and right sleeve plates when viewed from the article loading / unloading side. Good. The shelf plate 18 is a topmost shelf plate 18 which is hooked in a plurality of stages in the vertical direction and is shown in FIG.
An air purifier 30 as air purifying means is attached to the shelf plate 18 at the left end.

The shelf 18 to which the air purifier 30 is attached and the other shelf 18 located at the same height side by side with the shelf 18 extend across the shelf 18 and the air supply path 26. The air duct 24 including the intake path 28 is incorporated. The air duct 24 is originally an air passage that is continuous in the horizontal direction. As shown in FIG. 4 and FIG. 8, in the air duct 24, in the portion of the shelf plate 18 to which the air cleaner 30 is attached, the air duct 24 and the intake path are provided in the lengthwise direction of the air duct 24 by the air blocking plate 32. It is divided into 28. A plurality of horizontal air supply ports 36 are formed in the air supply path 26, and a plurality of horizontal air supply ports 38 are formed in the intake path 28.
In FIG. 1, the symbol E indicates the formation range of the air supply port 36, and the symbol I indicates the formation range of the intake port 38.

The air purifier 30 purifies the air sucked from the intake port 38 of the intake path 28, sends it to the air supply path 26, and discharges it from the air supply port 36. The air cleaner 30 has, for example, a photocatalytic titanium oxide filter, adsorbs and decomposes fine dust floating in the air, sterilizes bacteria in the air, and sterilizes. In FIGS. 3, 4, and 8, reference numeral 46 indicates an intake port of the air cleaner 30, and the intake port 46 communicates with the intake path 28. Reference numeral 48 indicates an air supply port of the air purifier 30, and the air supply port 48 communicates with one end of the air supply path 26.

The illustrated embodiment is a double shelf as described above and includes an air duct 24 and an air purifier 30.
Are two rows of shelf boards 18 arranged side by side in the depth direction.
Are individually incorporated into. Purified air is discharged horizontally forward from a plurality of air supply ports 36 of the air supply passage 26 on each of the front surfaces of the two rows of shelf boards 18, that is, on the side of the article take-out surface, and a plurality of intake air paths 28 are provided. The surrounding air is sucked horizontally by the intake port 38.

The shape of the air duct 24 is shown in FIG. Figure 7
In, the shelf 18 in which the air duct 24 is incorporated is
At least a frame 34 including a vertical wall is provided on the side of the storage / removal surface of the stored items. A flat cross-section hat-shaped member 44 and a flat channel-shaped member 45 are provided on the lower surface side of the shelf plate 18.
The air duct 24 formed of a space having a rectangular cross section formed by being fitted to each other is fixed. The part shown in FIG. 7 is a part of the air supply path 26, and an air supply port 36 is formed in the air duct 24 on the side of the take-in / out side of the stored articles. As described above, the plurality of air supply ports 36 are formed side by side in the horizontal direction. Further, the air supply port 36 is formed in a direction to horizontally inject air in the air supply path 26, and the flow of air horizontally discharged from the air supply port 36 is bent downward by the frame 34. It is like this.

The portion of the intake path 28 is also the above-mentioned air supply path 2
The cross-sectional shape is the same as that of 6, and an intake port 38 similar to the air supply port 36 is formed. An air filter is installed in the air cleaner 30. This air filter can be replaced and maintained regularly.
A door for attaching and detaching the air filter may be provided on the front side wall surface of the air purifier 30.

An air supply path 26 constructed as shown in FIG.
According to the air duct 2 sent from the air purifier 30
Purified air passing through 4 is discharged from the air supply port 36 toward the front in the horizontal direction. However, since the vertical wall of the frame 34 of the shelf plate 18 exists in the front in the discharge direction, the air discharged in the horizontal direction is bent downward by the inner surface of the frame 34. Therefore, the discharged air flows downward along the front surface of the shelf 10. On the other hand, since the plurality of intake ports 38 of the intake path 28 are also configured similarly to the air supply port 36 of FIG. 7,
Air is sucked in from below the front of the shelf 18. As a result, the air discharged downward from the air supply port 36 is gradually changed in direction, and in the vicinity of the intake port 38, the air is directed upward and is sucked from the intake port 38. In this way, the air circulating on the front surface of the shelf 10 is sucked through the intake port 38, purified by the air purifier 30, and again discharged through the air supply port 36.

In the embodiment shown in FIGS. 1 to 7, the air duct 24 is formed on the shelf plate 18 which is continuous at the same height in the lateral direction, and the air purifier 3 is attached to one of these shelf plates.
Although 0 is attached, the air duct 24 and the air purifier 30 may be incorporated in the top plate 16. The shape of the air duct incorporated in the top plate 16 may be the same as the shape shown in FIG. 7. Further, the air duct 24 and the air cleaner 30 may be incorporated in the underframe 12. In this case, it is preferable that the air supply port discharges air upward and the air intake port sucks air downward.

1 to 6, reference numerals 20 and 22
Shows a side panel attached to the side of the shelf 10. Further, reference numeral 40 indicates a humidity control device. Humidity control device 40
Is attached to the side panel 20 and has an air intake port 42 and an exhaust port 43 on the inner surface side of the side panel 20. The air intake 42 sucks in a part of the air in the rack collected around the intake path 28 to dehumidify it, and in some cases humidifies it. The air whose humidity has been adjusted by the humidity control device 40 is sent from the communication path 45 to the intake path 28 via the outlet.
Air purifier 3 together with the air taken in through the intake port 38
It is purified by 0 and sent to the air supply path 26, so that the humidity environment of the shelf 10 can be maintained appropriately. Whether or not the humidity control device 40 is provided is arbitrary.

According to the embodiment described above, the air duct 24 extends in the horizontal direction, and the air duct 24 extends in the horizontal direction.
The air purifier 30 has a simple structure in which the air supply path 26 and the intake path 28 are divided according to 2.
Directly connected to. Therefore, the air purified by the air purifier 30 is efficiently guided to the air supply path 26 of the air duct 24 with a large amount of air, and is discharged from the air supply port 36. In this way, the air around the shelf 10 and the air around the article storage can be efficiently circulated, the number of air circulations per unit time can be increased, and the environment around the shelf 10 and the environment around the article storage can be promptly improved.

The air duct 24 is integrated by adding the plate 44 to the shelf plate 18 and does not need to be individually formed as a duct. Therefore, there is an advantage that the number of parts is small, and one continuous duct. Since 24 is divided into the air supply path 26 and the intake path 28 by the air blocking plate 32, the structure is simple, and the environment improving device for the container can be obtained at low cost. Furthermore, by integrally incorporating the air duct 24 into the shelf plate 18 or the top plate 16, even in the case of a multiple-type storage body in which the support surface 14 divides the storage / removal surface of the storage article into a plurality of storage shelves 18 or Top plate 1
Since the air duct 24 can be continuously formed over the area 6, the air duct 24 can be easily formed.

Next, the effects obtained by the present invention will be described together with various measurement data when the present invention is adopted. Although there is not a lot of experimental data, if the wind with a wind speed of about 0.5 m / sec or more directly hits the stored items, the response of the moisture content of the stored items to changes in relative humidity will become faster, which is not desirable. It is said. Therefore, we developed and designed the wind speed when it hits the stored items to be 0.5 m / sec or less. To that end, FIG.
As shown in FIG. 5, by increasing the number of outlets 36, the velocity of the air discharged from each outlet 36 is reduced. Further, as described with reference to FIG.
The air discharged from the horizontal direction is applied to the frame 34 of the shelf plate 18 to reduce the wind speed, and the wind direction is directed downward so that the strong wind does not hit the stored items directly. This prevents wind damage to the stored items.

Next, the ventilation frequency per unit time when the technical idea according to the present invention was adopted was measured in comparison with the case where the invention according to the above-mentioned application was adopted. The result is shown in FIG. Measurements were carried out at a frontage having 12 consecutive stations, and measurement was performed at 2 stations, 4 stations, 6 stations, 8 stations, 10 stations, and 12 stations. In FIG. 9, a curve A shows the case where the technical idea of the present invention is adopted, and a curve B shows the case where the invention according to the previous application is adopted. As is clear from the curves A and B, by adopting the technical idea of the present invention,
The number of ventilations per unit time is about 10 times that of the invention according to the previous application at any measurement point, which shows that the environmental improvement efficiency is high.

The wind speed from the air supply port 36 when the technical idea of the present invention was adopted was measured while changing the number of the air supply ports 36. The shelves to be measured had a structure of 10 stations, and measurement was performed at each station position. The diameter of the air supply port was 10 mm. In FIG. 10, the curve a has 15 air ports in each station, and the curve b has 20 air ports in each station.
The curve c has 40 air ports in each station, and the curve d has 10 air ports in the 2nd and 3rd stations, and 1 from the 4th station.
40 stations up to the 0th station, curve e has 15 stations for the second and third stations, 40 stations from the 4th station to the 10th station, and curve f has the second station and the third station for the number of outlets Shows the measurement results of 20 pieces, 40 pieces from the 4th station to the 10th station. The wind source or air purifier is installed in the first station. As you can see from this result, the wind speed becomes faster as it approaches the wind source. In particular, if the number of air supply ports is small as a whole, the wind speed becomes faster, and the wind speed becomes remarkably faster as it is closer to the wind source, which is not desirable. It was also found that a uniform air velocity could be obtained by decreasing the number of air outlets near the wind source and increasing the number of air outlets far from the air source. Among the measured ones, the number of air outlets for which the curve e was obtained was 15 at the 2nd and 3rd stations, and 40 from the 4th station to the 10th station. It is less than sec and is most desirable.

Then, next, the number of air supply ports set to 15 and 40 was measured by changing the number of stations. The result is shown in FIG. The curve a shows the measurement results of 10 stations, the curve b shows 9 stations, the curve c shows 6 stations, and the curve d shows the measurement results of 3 stations. Wind speed of almost 0.5m /
It is less than sec.

FIG. 12 shows the test results regarding the disinfecting effect. 90m diameter with mold medium inside and outside the shelf
The petri dish of m was placed at 5 places, and the dropping bacterium test was conducted intentionally under bad conditions. After the operation of the air purifier, the falling bacteria were collected every certain time and the culture was detected. The result is shown in FIG.
Shown in. In FIG. 12, a curve a is detected inside a shelf incorporating the inventive idea, a curve b is detected inside a shelf incorporating the inventive idea of the previous application, and a curve c.
Indicates those detected outside the shelf. The horizontal axis is the operating time, and the vertical axis is the attenuation rate. As can be seen from FIG. 12, it is understood that the one incorporating the inventive idea of the above-mentioned application is also excellent in the sterilizing effect, but the shelf incorporating the inventive idea is further excellent in the sterilizing effect. I understand.

Further, according to the shelf incorporating the concept of the present invention, it was found that what was in a strongly acidic environment before the operation was improved to a neutral environment, that is, a clean environment after 24 hours of operation. In this method of measuring the acid / alkaline environment, an environment monitor was installed in the article storage block of each shelf, and the change in color was judged by comparing with a color scale. As a result of measuring the invention incorporating the invention idea according to the earlier application, the environmental improvement effect was recognized, but the strong acidity before the operation became weak acid after 24 hours of operation, and the idea of the present invention was adopted. It was found that the shelf has a higher environmental improvement effect.

According to the shelf incorporating the concept of the present invention, the inside of the container is constantly air-conditioned and the temperature and humidity are controlled, so that each article storage space is maintained under stable environmental conditions.
Further, when the humidity controller is attached, the humidity condition is maintained even better.
