Next, the dust collecting performance of the storage shelf 1 according to the present embodiment will be described. The dust collection performance of the storage shelf 1 was evaluated by an attenuation test of the concentration of dust in the atmosphere surrounding the storage shelf 1. As the dust collection filter 32 of the air purification unit 3, a filter (JIS colorimetric method 90%) and a pre-filter integrated were used. The test method of the above attenuation test is as follows: (1) A test chamber (floor area: about 4000 mm × 4000 mm, ceiling height: about 3000 mm) composed of all stainless steel walls is placed in the same configuration as the storage shelf 1. 20
The shelf under test 1A shown in FIG. Here, by using stainless steel as the wall material in the test room, the influence of the dust concentration attenuation due to the adhesion of the dust to the wall surface can be reduced. (2) An incense was fired in the test chamber in a sealed state, and the air in the test chamber was well stirred by a fan. (3) Digital dust meter (hereinafter simply referred to as "dust meter")
Then, when the dust concentration reached 0.3 (mg / m ³ ), the fan was stopped and the air purification unit 3 of the storage shelf 1 was operated. (4) Simultaneously with the operation of the air purification unit 3, measurement of dust concentration was started by the dust meter, and the measurement results were sequentially recorded by a plotter arranged outside the test chamber. (5) The number of paths of the air duct in the storage shelf 1 (the number of paths is 1 for the one-way blowout, and the number of paths is 2 for the two-way blowout)
And the installation location of the above-mentioned dust meter, the above (2)-
The operation of (4) was repeated. (6) For comparative evaluation, the dust concentration in the test chamber when the air purification unit 3 was naturally attenuated without operating the air purification unit 3 in the above (3) was also measured by the dust meter.

On the shelf of the second stage / first stage of the shelf 1A to be tested shown in FIG. 20 (the position indicated by the circled symbol 1 in FIG. 20A).
Then, the dust meter 20 was installed, and the attenuation tests (2) to (6) were performed. As a result, a graph showing the relationship between the dust concentration (mg / m ³ ) and the time (min) shown in FIG. 21 was obtained.

(Test Example 1) In FIG. 21, a black circle "●"
Represents the test result when the dust concentration in the test chamber is naturally attenuated. From the broken line a, it can be seen that in the case of natural attenuation, the dust concentration is attenuated with the passage of time due to the effect of air flowing out of a small gap in the test chamber. That is,
In this case, the dust concentration, which was 0.3 (mg / m ³ ) at the start of the measurement, was changed to 0.1 after the start of the measurement (min).
Attenuated to a dust concentration of 95 (mg / m ³ ).

(Test Example 2) In FIG. 21, a broken line b on which a black triangle “▲” is plotted indicates a test result when the dust concentration in the test chamber was attenuated by the operation of the air purification unit 3. I have. In this attenuation test,
Book loading rate: 100%, number of air duct paths: 1, direction of circulating airflow; downward. In this case, from the polygonal line b, the dust concentration of 0.3 (mg / m ³ ) at the start of the measurement is changed to 0.07 after the start of the measurement (min).
It can be seen that the dust concentration is greatly reduced to (mg / m ³ ).

(Test Example 3) In FIG. 21, a broken line c in which a black square "■" is plotted indicates a test result when the dust concentration in the test chamber was attenuated by the operation of the air purification unit 3. I have. In this attenuation test,
Book loading ratio: 100%, number of air duct paths: 2, direction of circulating airflow; downward. In this case, the dust concentration, which was 0.3 (mg / m ³ ) at the start of the measurement, was changed from the above-mentioned line c to 0.04 at 60 (min) after the start of the measurement.
It can be seen that the dust concentration is greatly reduced to a dust concentration of 3 (mg / m ³ ).

As is clear from the results of the above (Test Example 2) and (Test Example 3), in the storage shelf 1 having the above configuration, it was confirmed that the higher the number of air duct paths, the higher the dust collection performance was obtained. Was done. Further, in both (Test Example 2) and (Test Example 3), it was confirmed that a higher dust collection performance was obtained than in the case of the natural attenuation of (Test Example 1).

Next, the dust meter 2 is placed on the shelf 1A to be tested shown in FIG.
0 was set, and the attenuation tests (2) to (6) were performed. As a result, a graph shown in FIG. 22 showing the relationship between the dust concentration (mg / m ³ ) and the time (min) was obtained. In this attenuation test, the book loading ratio was 100%, the number of paths in the air duct was 2, the blowing direction of the circulating airflow was downward.

In FIG. 22, a polygonal line a indicates a test result when the dust concentration in the test chamber is naturally attenuated. Also, in FIG. 22, circled symbols 1, 2, 3,.
Lines indicated by 4 and 5 indicate test results corresponding to the respective installation positions of the dust meter 20 shown in FIG.

As shown in the graph of FIG. 22, even if the installation location of the dust meter 20 is changed, the dust concentration in the storage section of the shelf 1A under test is attenuated at substantially the same attenuation rate, and It was confirmed that a substantially uniform dust collecting effect was obtained over the entire area. Further, as shown by the polygonal line 5 in FIG. 22, it has been found that the dust collecting effect can be obtained outside of the shelf 1A under test as far as the periphery of the shelf 1A is tested. The reason is,
This is because the air around the shelf under test 1A is also entrained by the air curtain, and the entrained air is purified by the air purification unit 3.

Next, the deodorizing performance of the air purification unit 3 will be described. Octyl alcohol (2-ethylhexyl alcohol) was used as an odor specimen for confirming the odor intensity. There are many unclear points about the odor component of this octyl alcohol. Therefore, in conducting the deodorization test for evaluating the deodorizing performance, first, a total of six persons (including one female)
An odor intensity confirmation test was conducted by a panel of (name).

As a test method of this odor intensity confirmation test, 0.7 g of octyl alcohol was intermittently heated and evaporated in a SUS container having a volume of 1 m ³ , and sensory evaluation was performed at predetermined intervals (theoretically). The peak value of the sample concentration of
About 20 ppm). In addition, nine samples were used as odor samples. Since the odor concentration reached the peak in the fifth odor sample, the test data of the fifth odor sample was used.

The above six panelists gave N
o. The odor intensity of each of the odor samples 1 to 5 is “6” shown in Table 1.
The sensory evaluation was performed to find out which level in the "Step Odor Strength Table". Table 2 shows the results of the sensory evaluation.

[0073]

[Table 1] 6-stage odor intensity table

[0074]

[Table 2] Sensory evaluation

Table 3 shows the sample concentration (gas concentration) of each odor sample and the average odor intensity of the sensory evaluation by the panelists based on the sensory evaluation shown in Table 2.

[0076]

[Table 3]

FIG. 23 shows the results of the odor intensity confirmation test shown in Table 3, that is, the odor intensity of octyl alcohol (6
4 is a graph showing the relationship between step strength) and odor concentration (ppm). From this graph, it was found that the odor component of the octy alcohol had an odor concentration of about 22 ppm and an odor intensity of one stage (odor that could be finally detected). This is a very high concentration when compared to major malodorous components such as ammonia.

Next, based on the test results of the above-mentioned odor intensity confirmation test, a deodorization test was conducted using octyl alcohol (2-ethylhexyl alcohol) as a test odor. As a test method of this deodorization test, 0.3 g (about 60 ppm) of octyl alcohol was heated and evaporated in a SUS container having a volume of 1 m ³ , and after stabilization, the air purification unit 3 was operated to check the remaining octyl alcohol. A concentration decay test was performed. As the deodorizing means 33 of the air purifying unit 3, a unit provided with a photocatalyst (titanium oxide catalyst) and a special INV lamp was used.

This attenuation test was repeated three times by the same operation. As a result, the residual concentration of octyl alcohol was
As shown in Table 4, it became clear that the attenuation occurred with the passage of time.

[0080]

[Table 4]

Based on Table 4 above, a graph showing the results of the above-mentioned deodorization test, that is, the relationship between the residual concentration (ppm) of octyl alcohol and the time (min) was obtained as shown in FIG. As a result, the residual concentration of octyl alcohol, which was about 60 ppm at the start of the test, can be rapidly attenuated to about 5 ppm (about one-twelfth of the initial concentration) 15 minutes after the start by the air purification unit 3. Became clear. In addition, the results of the above three tests showed that the residual concentration of octyl alcohol can be attenuated without much variation.

The results of the above-mentioned deodorization test can be represented by the odor intensity shown in FIG. 23, which was about 2.5 at the start of the test, less than 1 (22 ppm) after 5 minutes, and less than 1 (22 ppm) after 15 minutes. It shows that the odor intensity can be reduced to 0.5 (8 ppm) or less. As a result, the air purification unit 3
It has been found that a sufficient deodorizing effect can be obtained. In addition, since the octyl alcohol is one of the mold odor components, it is determined that the air purification unit 3 is very effective for mold odor.

Next, the self-standing shelf under test 1B shown in FIG.
The results of measuring the temperature, humidity, falling bacteria count, dust concentration, environmental monitor, and the like in the storage section using the above will be described. Thermo-hygrometers 21a, 21b, 21c, and 21 are provided at the portions of the shelf under test 1B indicated by circles 1, 2, 3, and 4, respectively.
d, Petri dishes for falling bacteria 22a, 22b, 22c,
22d were installed, and the temperature and humidity inside and outside the storage part of the shelf 1B to be tested and the number of falling bacteria were measured. Further, an air checker 23a as a dust concentration measuring instrument was installed in the storage section of the shelf 1B to be tested, and the dust concentration inside and outside the storage section of the shelf 1B was measured. Further, an environmental monitor 24a is installed on the outer surface of the shelf under test 1B, and an environmental monitor 24b is installed in the storage section of the shelf under test 1B.
The environmental cleanliness inside and outside the storage section B was measured.

FIG. 26 shows the thermo-hygrometers 21a and 21b,
It is a graph which shows the temperature / humidity measurement result inside and outside the storage part of the said shelf under test 1B by 21c, 21d. As shown in this graph, before the air purification unit 3 operates,
The temperature and humidity environment in the storage unit of the shelf 1B under test is such that the lower part of the storage unit (circled symbol 3) is low temperature and high humidity, the upper part of the storage unit (circled code 1) is high temperature and low humidity, and the middle part of the storage unit (circled). Symbol 2)
Indicates an environment having an intermediate temperature and humidity.

Here, comparing the upper and lower sections,
The maximum temperature difference before the operation of the air purification unit 3 is 1.
9 (° C.), the average temperature difference was 1.7 (° C.), the maximum relative humidity difference was 6 (%), and the average relative humidity difference was 4 (%).

On the other hand, comparing the upper stage and the lower stage after the operation of the air purification unit 3 (switch ON), the average temperature difference is 0.3 (° C.) and the average relative humidity difference is 1 (° C.).
(%), And it can be seen that the temperature and humidity environment in the storage unit is improved to a substantially averaged state.

FIG. 26 shows a comparison between the temperature and humidity environment (circled symbols 1 to 3) inside the storage section of the shelf 1B to be tested and the temperature and humidity environment outside the storage section (circled symbols 4). In addition, it has been found that, by operating the air purification unit 3, the temperature and humidity environment inside the storage unit changes and converges while being affected by the temperature and humidity environment outside the storage unit. This indicates that an air flow (convection) is occurring in the storage section of the shelf under test 1B, which means that the storage environment of the stored items is maintained in a stable temperature and humidity environment.

FIG. 27 is a graph showing the relationship between the dust concentration (mg / m ³ ) measured by the air checker and the operation time (min) of the air purification unit as a graph. As is clear from this graph, after the operation of the air purification unit 3, the dust concentration is attenuated with the passage of time, and the air in the storage section is purified, and the dust concentration is reduced at a low dust concentration under general environmental conditions. It turned out to be effective even if it did.

Table 5 shows the operating time (min) of the air purification unit 3 and the petri dishes 22a, 22b,
The measurement result of the number of falling bacteria consisting of mold and bacteria collected in 22c and 22d is shown. The medium is potato dextrose agar.

[0090]

[Table 5]

As is evident from Table 5, the number of bacteria falling was 13.5 when the average number of bacteria per petri dish was 13.5 when the air purification unit 3 was not operated. (Min) When operated, the average number of bacteria per petri dish was reduced to 1.7.

As described above, it was revealed that the air purification unit 3 also had a sterilization performance. In addition, similar results were observed at a portion outside the shelf to be tested, and it was found that the air purification range extended to outside the storage shelf.

FIG. 28 (a) shows the air purification unit 3
5 shows a measurement result by the environmental monitor 24a before the operation of the above. FIG. 28B shows the air purification unit 3.
7 shows the measurement results obtained by the environmental monitor 24b after the operation of (1).

According to the measurement results by the environmental monitors 24a and 24b, as shown in FIG. 28 (a), a reaction at level 1 indicating an acidic environment was observed before the operation of the air purification unit 3, As shown in FIG. 28 (b), after the operation of the air purification unit 3, the level 2 indicating the clean environment is obtained.
It was found that the cleanliness of the environment was improved to about level 3, which indicates an alkaline environment, and that acidic pollutants were removed. This indicates that the storage section is a favorable environment as a storage environment for the stored items.

The present invention, besides the storage shelf 1 according to the present embodiment, includes, for example, an exhibition table 101 as shown in FIG.
The present invention can be widely applied to an open type display case 100 composed of a support 102, a top plate 103, and the like, and a storage body such as a movable shelf, a fixed shelf, a display shelf, a closet, a shoe box, a storage room, and a toilet.

The present inventors have found that the structure of the air discharge port, the difference in the direction of the discharged air due to the difference in the structure, the air circulation effect in the storage section due to the difference in the direction of the discharged air, and the inside of the storage section. The air purification effect was examined, and the more preferable structure of the air outlet was examined.
FIG. 30 shows the transition of the structure of the air outlet examined in a stepwise manner, and FIGS. 31 and 32 show the state of the air flow when the air outlet has a desirable structure.

FIG. 30 (a) has the same structure as the shelf plate / exhaust duct shown in FIG. 4, and the clean air sent into the exhaust passage 5c of the shelf / exhaust duct 5 is
exhaust port 5d formed on the side surface of reinforcing plate 5b forming
From the horizontal direction, and further formed on the side surface (surface along the opening at the front of the storage shelf) of the shelf plate material 5a.
e is discharged horizontally to the outside of the storage shelf. The discharged air flows so as to wrap around the opening of the storage shelf from outside as described with reference to FIG. 13 and thereafter, is sucked from the intake port, purified by the filter, and discharged again from the exhaust port 5e.

In this way, even with the structure of the exhaust port as shown in FIG. 30A, an air curtain is formed around the storage shelf, and fine particles and fine particles from the opening of the storage section are removed. Prevent invasion of pests, etc., and contamination of air in the storage section,
In addition, the air inside the storage body and around the storage body can be purified. However, instead of discharging air horizontally from the exhaust port, if the structure of the exhaust port is such that air flows linearly toward the intake port, an efficient and stable air curtain can be made. It should be possible to circulate air efficiently. That is, when the exhaust port is at the top and the intake port is at the bottom, air is discharged from the exhaust port directly below.

Therefore, as shown in FIG. 30 (b), the clean air sent into the exhaust path 5c of the shelf plate / exhaust duct 5 is formed at the lower part of the reinforcing plate 5b forming the exhaust path 5c. It is configured to be discharged downward from the exhaust port 5f. This can also achieve the intended purpose. However, when the storage items 40 are placed on the shelf plate 6 below the shelf plate / exhaust duct 5, the air discharged downward from the exhaust port 5f flows at substantially the same flow speed as the discharge speed. It has been found that there is a possibility that the dust directly hits the container 40 and damages the stored item 40.

Then, next, as shown in FIG.
After the clean air sent into the exhaust path 5c of the shelf plate / exhaust duct 5 is horizontally discharged from the exhaust port 5d formed on the side surface of the reinforcing plate 5b forming the exhaust path 5c, the shelf board material 5a And a structure in which the flow in the horizontal direction is temporarily stopped by hitting the inner surface of the shelf 5a, and the length direction of the shelf 5a (when the storage body is viewed from the front) is located between the side of the reinforcing plate 5b and the inner surface of the shelf 5a. 5g slit-like space
Is formed, and air is discharged from the space 5g. Here, the exhaust port 5d is a first exhaust port, and the slit-shaped space 5g is a second exhaust port. According to the embodiment shown in FIG. 30 (c), the clean air discharged in the horizontal direction from the exhaust port 5d hits the inner surface of the shelf 5a and is temporarily prevented from flowing in the horizontal direction. The flow velocity of the air discharged from the slit-shaped space 5g, which is the exhaust port, is reduced, and the horizontal component of the air flow discharged from the exhaust port 5d and the component of the air flow that is going downward from the space 5g. Are discharged diagonally downward and out of the storage body.

As described above, according to the embodiment shown in FIG. 30C, the flow velocity of the air discharged from the slit-shaped space 5g is reduced, so that even if this air flow hits the storage 40, wind damage is reduced. You. In addition, since air is discharged obliquely downward from the storage space 5g to the outside of the storage body from the slit-shaped space 5g, which is the second exhaust port, the amount of exhaust air hitting the storage object 40 is small, and wind damage is reduced in this regard.

In any of the embodiments, clean air flows so as to wrap around the outside of the housing, and the air inside the housing is entrapped and circulated in this air flow. FIG.
FIG. 32 shows a result of analyzing by simulation how air flows in the embodiment shown in FIG. 30 (c). In the embodiment shown in FIG. 30 (c), the air discharged obliquely downward from the slit-shaped space 5g flows along the front surface (opening) of the housing 1
It flows downward toward the lower intake. In FIG. 32, reference numeral 41 indicates an airflow flowing along the front surface of the housing 1. A part of the air flow 41 enters the upper space between the upper and lower shelves 6 by the wind pressure of the air flow 41 as indicated by reference numeral 42. In the lower space between the upper and lower shelves 6, 6, as indicated by reference numeral 43, the air is sucked by the airflow 41, the direction of the airflow in the lower space is changed, and a part of the air between the shelves 6, 6 Is carried out. In this way, the shelf 6,
The air between 6 is also attracted to the air flow 41 and circulates, and the air inside the housing is also purified.

It is desirable that the clean air discharged from the exhaust port is uniformly discharged from the opening surface of the storage body. Similarly, the air sucked from the intake port is uniformly suctioned from the opening surface of the storage body. It is desirable to be done. Therefore, in a portion where the amount of air to be discharged or sucked tends to be insufficient, it is preferable to take measures such as increasing the area of the outlet or the inlet or increasing the number. FIG. 33 shows a case where discharge ports 5d are provided at regular intervals on the side surface of the shelf plate / exhaust duct 5 and some of the discharge ports 5d are appropriately closed in a portion where a large amount of air is discharged, thereby achieving a uniform discharge amount. It is.
The intake port may be similarly configured.

Next, another embodiment of the storage body with an air purifying function according to the present invention will be described with reference to FIGS. In this embodiment, the configuration is simplified as compared with the embodiments described so far, but the initial object can still be sufficiently achieved.

In FIG. 34, the storage shelf 1 has a support 9, a top plate 7, a shelf plate 6,
It has a side plate 12 and the like. The shelf 6 may be formed in a plurality of stages, or may be formed only in one stage. In any case, on the uppermost shelf 6, an air purification unit 3 as an air purification means is arranged near the side plate 12. The air purification unit 3 includes a dust collection filter, a deodorizing unit, a sirocco fan 31 as an air circulation unit, an intake unit, an exhaust unit, and the like, as in the above-described example. An exhaust path 35 is integrally connected to the exhaust unit.

Since the side plate 12 has an internal space having a width G between the side plate 12 and the outer surface of the column 9, this internal space is used as an intake duct. Side edges of the side plate 12, more precisely when the storage shelf 1 is viewed from the side,
2 are bent toward the main body of the storage shelf 1 when viewed from the front, and the edge of the bent portion is applied to the outer surface of the support 9. It is usual that there is a gap through which air can flow between the edge of the bent portion and the outer surface of the column 9 which forms a part of the storage shelf 1 body.
This gap communicates with the intake duct in the side plate 12.

A part of the shelf 6 constitutes an intake path communicating with an intake duct in the side plate 12, and the intake path 36 of the shelf 6 is directly connected to the intake section of the air purification unit 3. The shelf 6 also serves as an exhaust duct, and the exhaust path 35 is directly connected to the exhaust duct of the shelf 6. As a result, the exhaust path 35 and the exhaust duct are integrated in the intake section of the air purification unit 3. The intake path and the exhaust duct formed on the shelf 6 are separated by a partition plate or the like. An appropriate number of exhaust ports 37 are formed on the front surface of the shelf 6, and the exhaust ports 37 communicate with the exhaust duct. The exhaust port 37 is formed over the entire frontage direction of the storage shelf 1, and accordingly, the exhaust duct formed on the shelf 6 is also a long exhaust duct over the entire frontage direction of the storage shelf 1. In the example shown in FIG. 35, the storage shelves 1 have a triple configuration, the exhaust ports 37 are formed over the entire frontage direction of the triple shelf 6, and a corresponding long exhaust duct is formed.

As described above, according to the embodiment shown in FIG. 34, no special air inlet is provided, and the gap originally generated between the main body of the storage shelf 1 and the side plate 12 is used as the air inlet. ing. Further, the purified air discharged from the air purification unit 3 is discharged from an exhaust port 37 of the shelf 6 through a duct of the shelf 6 in which the air purification unit 3 is installed. Therefore, the configuration is simpler than that of the previously described embodiment. Nevertheless, tests have shown that an initial effect can be obtained. Next, the test results will be described.

As shown in FIG. 35A, the air purifying unit is installed at the left end of the uppermost shelf 6, and the purified air is discharged from the exhaust port of the shelf 6. FIG. 35 (a)
In (b), the line with the arrow indicates the result obtained by simulation of the direction in which the air discharged from the exhaust port flows. As can be seen from this figure, the purified air flows along the opening surface of the storage shelf 1 while diffusing from the upper shelf plate 6. The average wind speed at the bottom is 0.04m /
It was confirmed that an air flow was generated so as to wrap around the opening surface, even at a slight wind speed of about min. The air flowing along the opening surface is sucked from the gap between the main body of the storage shelf 1 and the side plate 12, purified by the air purification unit, and purified while being circulated by the above-described exhaust and intake air.

In order to confirm the air purifying effect of the storage body with the air purifying function according to the above embodiment, a drop bacteria measurement test was performed using the air checker as described above. In order to compare the effects, the air purification unit 3 is shown in FIGS.
(A) is provided at the same position as that shown in (a), and a special intake port is not provided, and an exhaust duct is provided only on a shelf plate for one frontage, and an air purification unit 3 as shown in FIG. The measurement was performed before the air purifying unit 3 was operated and immediately after the air purifying unit 3 was operated for 24 hours in the case where the exhaust port was provided on the shelf plate for the frontage. The containers used for the measurement are shown in FIGS.
As shown in FIG. 6, the frontage is triple and the shelf plate 6 has six steps.
There are five measurement points indicated by numerals 1 to 5 surrounded by a square in FIG. Board, uppermost right shelf, and lowermost right shelf. The measurement items are mold and bacteria.

Tables 6 and 7 show that, as in the example shown in FIG.
Table 6 shows the measurement values before the air purification unit is operated, and Table 7 shows the measurement results immediately after the operation for 24 hours. Tables 8 and 9 show the measured values of the storage shelf 1 having an exhaust duct and an exhaust port only in one frontage.
Indicates the measurement results before the operation of the air purification unit, and Table 9 indicates the measurement results immediately after the operation for 24 hours.

Table 6 Table 7 Table 8 Table 9

As can be seen from Tables 6 and 7, those having the intake and exhaust ducts across the width of the front face of the storage shelf have a 71.0% improvement effect by operating the air purification unit for 24 hours. I understand.
On the other hand, as can be seen from Tables 8 and 9, the storage shelf 1
In the case where the intake and exhaust ducts are provided only in the frontage, the improvement effect when the air purification unit is operated for 24 hours is 17.5%. It was found that the effect of improving the difference by 53.5 points was higher in the storage shelf than in the storage shelf having the intake and exhaust ducts only for one frontage in the lateral direction.

According to the above-described embodiment in which the intake duct and the exhaust duct are provided substantially all over the housing in the frontage direction of the housing, the air purifying unit is operated for 180 minutes. There was an improvement effect of 4%, and it was found that there was immediate effect. However,
It has been found that it is sufficient for the storage body to be able to gradually improve the environment even with the lapse of time, and a satisfactory effect can be obtained even in a storage shelf without a special intake port as shown in FIG. In addition, if the intake duct and the exhaust duct are provided over almost the entire frontage direction of the storage body, it is possible to obtain a sufficiently satisfactory effect,
In addition, even in the case where the exhaust duct and the exhaust port are provided in a limited range of only one frontage, a satisfactory effect can be obtained as the operation time of the air purification unit elapses even if there is no immediate effect. I understood.

[0115]

According to the first to tenth aspects of the present invention, purified air is circulated in the storage section of the storage body,

According to the ninth aspect of the present invention, the shelf plate also serving as an air duct has an exhaust port for exhausting air from the air duct in a horizontal direction, and an inner surface for temporarily blocking the flow of air exhausted from the exhaust port. And a second exhaust port for discharging the air blocked by the inner surface downward, so that the flow velocity of the air discharged from the exhaust port is blocked by the inner surface of the shelf and weakened. 2 is discharged from the exhaust port. Even if this air flow hits the storage, the air flow is weakened,
Wind damage is reduced. In addition, the airflow discharged from the second exhaust port is discharged obliquely downward to the outside of the storage body, so that the amount of exhaust hitting the storage material is small, and wind damage is reduced in this respect as well.

According to the tenth aspect of the present invention, the air duct forming the intake path or the exhaust path includes a plurality of storage shelves in which a plurality of storage shelves in which the back surfaces of the storage portions are arranged back to back with a predetermined gap therebetween. Since it is arranged in the gap between the backs of the back to back, the air duct can be installed using the dead space of the storage body, and the storage body can be disassembled or significantly dismantled with the existing storage body The air duct can be assembled without remodeling.

According to the eleventh aspect of the present invention, since the odor in the air in the storage section can be removed by the deodorizing means, the contamination of the air in the storage section can be prevented.

According to the twelfth to sixteenth aspects of the present invention, no special air inlet is provided, but even if the operating time of the air purifying means becomes longer than a certain level, an air purifying effect appears. Satisfactory effects can be obtained for air purification of the body.

According to the thirteenth aspect of the present invention, since the space between the housing body and the side plate is used as the air inlet, it is not necessary to provide a special air inlet, and the configuration can be simplified. According to a fourteenth aspect of the present invention, an exhaust path and a duct are integrated with the exhaust part of the air purifying means. However, the configuration can be simplified by the shelf plate forming the intake path as in the invention of the sixteenth aspect.
