The other end of the duct 27 connected to the outlet 21c is connected.

With this configuration, the moisture inside the shelf removed by the wet / dry dehumidifier 21 is stored in the humidifier 25 at high humidity such as summer, and the humidifier 2 is stored at low humidity such as winter.
By dissipating moisture from 5, the humidity inside the shelf can be kept constant for a long time with a simple configuration.

In the third embodiment and each of the modifications, the heater 16 may be attached to the lower portion of the bottom plate 8.

In each of the first to third embodiments and the modifications, the shelf 1 has a back plate 9 on the back of the shelf body 2.
Although one having a closed surface was used, the present invention is not limited to this. Two surfaces having a door on the front surface of the shelf body 2 were closed or two surfaces having no back plate 9 were opened. It can also be applied to shelves. In this case, when the two surfaces are closed, the air inside the shelf does not flow to the outside, so that a gap (not shown) is provided between each shelf plate 11 and each of the side plates 5 and 6, the partition plate 10 and the back plate 9. Is formed, each through-hole 10a,
11a is not always necessary. Further, in the case where the two surfaces are opened, it is preferable that the through holes 10a and 11a are formed because the air inside the shelf flows to the outside. However, the air inside the shelf becomes uniform with time. The through holes 10a and 11a are not necessarily required even if the two surfaces are open.

In each of the first to third embodiments and the modified examples, the passage 12 is provided only in one side plate 6, but the passage 12 is formed in each side plate 5 and 6, and each passage 12 is formed. It may be configured to be connected to the air cleaning means 3 or the air cleaning means 20.

The present invention may be applied to a shoe box 39 as a lower foot shelf provided with an openable and closable door 38 having 38a. in this way,
By applying the present invention to a shoe box, it is possible to prevent the generation of mold on shoes and to obtain an effect of preventing odor.

The above-described comparative confirmation test of the clean air humidification, convection action, bacteriostatic effect and sterilization effect was carried out by using a shelf having an air environment adjusting function substantially similar to the shelf 1 shown in FIG. went. In addition, the graph showing each experiment data shows the maximum value and the minimum value of a plurality of data for each shelf, respectively.

As shown in FIGS. 15 and 16 (a), in a normal shelf, the humidity inside the shelf changes within a range of 67 to 78%, and the humidity changes differently depending on each part of the shelf. As shown in FIGS. 15 and 16 (b), in the shelf with the air environment adjusting function, the humidity inside the shelf changes in a narrow range of 55 to 60%, and the humidity change in each part of the shelf is constant. You can see that. This proved that an optimal humidity environment was created in the shelf for the stored items, and clean air humidification was confirmed.

Further, as a result of measuring the humidity at the corner inside each shelf, as shown in FIG. 17, it was found that the whole humidity was reduced and the humidity change was constant in the air environment adjusting function shelf. It was confirmed that the air conditioned by the action spread to the corner inside the shelf.

Further, the inside of each shelf was dew-condensed, and a sample in which mold was planted in the center of a filter paper spread on a petri dish containing potato dextrose agar was placed on each shelf to minimize the effects of falling bacteria. As a result of conducting the experiment in the
As shown in the figure, the normal shelf showed a large change in humidity of 45 to 99%, the growth of mold in the center of the sample was confirmed, and the growth of falling bacteria that were difficult to adhere was also confirmed. In the attached shelves, the humidity was converged in the range of 65 to 85%, the growth of mold at the center of the sample was suppressed, and the bacteriostatic effect was confirmed.

Further, under the same conditions as described above,
As a result of placing the petri dish containing potato dextrose agar and evaluating the eradication effect by the number of fallen bacteria, the number of fallen bacteria on the normal shelf was large and grew on the entire dish, but on the shelf with air environment adjustment function the fallen bacteria were removed. Since the number was small and they did not grow, the eradication effect was also confirmed.

The humidity control function in each of the second and third embodiments and the modifications is based on the premise that the environment in which the shelf 1 is installed is adjusted to a certain humidity range by an air conditioner. The same applies to a shelf not having the back plate 9 and having two open sides of the shelf main body 2, as shown in FIGS.
The air-conditioning equipment is not always necessary in the closed shelves (shoe boxes) 36 and 39 having the back plate 9 and the front door as shown in FIG. Further, in the moving shelf 30 as shown in FIG. 11, when the respective shelf main bodies 2 are focused so that the interval between them is about 20 mm or less, the effect of the humidity control function is not affected by environmental conditions. Can be obtained.
