Description

  The present invention relates to a display case in which an exhibit can be stored and displayed for a long period of time in an environment of good air quality in an art museum, a museum, a cultural property preservation hall, and the like.

  As a conventional display case of this type, a storage space containing an exhibit is enclosed and sealed with a transparent glass plate or the like, and the air in this storage space is provided with an air cleaning means having a fan and a filter. In general, it is made to circulate through (see, for example, Patent Document 1).

  The circulation path as described above can be expanded and contracted, a humidity control means is provided in the circulation path (see, for example, Patent Document 2), or nitrogen gas can be supplied to the accommodation space ( For example, see Patent Document 3).

Japanese Patent No. 2902359 Japanese Patent No. 38882473 JP 2004-81306 A

In the conventional display case as described above, since the air in the storage space is repeatedly circulated, if there is a contamination source in the storage space, the storage space and the entire circulation path are contaminated with high concentration, and an expensive chemical filter is used. However, since the capacity of the chemical filter that can be accommodated in the display case is limited, contamination may not be sufficiently removed.
Many of these sources of pollution are emitted gas from interior materials of exhibition stands and caulking materials to ensure airtightness in the containment space, and such emitted gases are generated even after the exhibition starts. There is.
There are aldehydes (formaldehyde, acetaldehyde), organic acids (acetic acid, formic acid), ammonia, and the like as a problem gas.

  Therefore, for newly produced display cases, the storage space is opened and the doors are opened in a state in which the exhibits are not stored, and waiting for exhausted gas from these interior materials to be exhausted, that is, “withered” However, in many cases, it is not possible to secure the time required for such “withering”.

  In addition, in the conventional display cases as described above, mass production is difficult and expensive materials are often used, so that not only the manufacturing cost is high, but also expensive chemical filters and dust filters must be replaced frequently. In addition, there are problems such as rising maintenance costs.

  On the other hand, the air conditioning equipment of exhibition rooms such as art museums and museums with display cases has evolved significantly in recent years, and some of them are equipped with chemical filters as well as temperature and humidity control. Therefore, although the air quality in the exhibition room deteriorates, the air in the exhibition room is very clean during closing, especially during the time before the next opening.

  The present invention pays attention to such purified air in the exhibition room, and by using this, it is possible to improve the air quality in the exhibition space of the exhibit with simple equipment, It is an object of the present invention to provide an exhibition case that can solve the problems such as the above-mentioned increase in manufacturing cost and maintenance cost that the conventional technology has.

According to such a configuration, when a visitor visits the exhibition room in which the display case is arranged and observes the exhibits in the display case, the on-off valve in the display case is closed and the blower is stopped. Thus, it is possible to prevent the air in the exhibition room, whose air quality has deteriorated due to the passage of visitors, etc., from entering the case main body of the display case and adversely affecting the exhibits.
At night or closed days when visitors do not visit the exhibition room, the air in the exhibition room is purified by the air conditioner, and the air quality is improved. When such an exhibition room is not used, especially after a certain amount of time has elapsed since the exhibition room was not used, the on-off valve in the display case is opened and the blower is operated to The air is ventilated with the air in the clean indoor space.
As a result, a small amount of emitted gas generated from pollution sources such as interior materials and caulking materials inside the case body is discharged outside the case body during the period when the case body is sealed, and the inside of the case body is cleaned in the exhibition room. The exhausted gas generated during the ventilation period is immediately exhausted as well as being filled with the discharged air.
Therefore, without providing an expensive air purification device in the display case itself, it is possible to improve the air quality in the case body even if the exhibition item is accommodated only by providing a simple ventilation device, The temperature and humidity can be maintained, and thus problems such as the above-described increase in manufacturing cost and maintenance cost, which the conventional technology has, can be solved. In addition, it is possible to promote withering even when the exhibits are accommodated.
