Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a humidifier installed in an exhibition case for displaying exhibits in museums, art galleries, etc. for viewing.

[Prior Art] In an exhibition case for displaying valuable items, in order to make it easier to see the exhibits displayed inside and to prevent theft and mischief, the exhibition space that houses the exhibits is completely separated from the outside while on display. It is important to create a sealed space that is blocked off.

However, when exhibiting antique works of art, etc., it is important to maintain appropriate humidity in the exhibition space for preservation purposes. For example, when handling lacquerware, etc., it is necessary to maintain a humid atmosphere of about 95%.

Therefore, conventionally, when an exhibition space needs to absorb moisture, a water receptacle such as a cup or tray is placed on the exhibition floor together with the exhibits as a moisture absorbing means to add moisture to the exhibition space.

[Problems that the invention aims to solve] However, with conventional moisture absorbing means, not only does the water receptacle get in the eyes of viewers, making it unsightly, but also when vibrations are applied to the display case due to earthquakes or other factors. When moving, etc., there is a risk that the water tray may topple or overflow, leading to accidents such as humidifying water flowing onto the exhibition floor and wetting the exhibits.

The present invention solves these problems and also facilitates maintenance. This is a new humidifying device for display cases.

[Means for solving the problem] In the present invention, an exhibition space and a base space formed below the space that can be opened to the outside are airtightly divided by an exhibition floor, and the space under this exhibition floor is A humidity box is installed on the side, and the inside of this humidity box is communicated with the exhibition space through a vent installed on the exhibition floor.
This moisture supply box is provided with a maintenance door for opening the interior of the moisture supply box to the space of the base portion, and a moistened water-absorbing polymeric material is placed inside the moisture supply box.

[Function] In other words, a moistened water-absorbing polymer material can impregnate and retain moisture at an extremely high rate without extracting it, and this can be stored in a moisture box that communicates with the exhibition space. Since the display space is placed in a high-humidity atmosphere, the moisture continuously evaporated from the water-absorbing polymer material can humidify the exhibition space.

In addition, the device of the present invention has a moisture box containing the polymer material at the bottom of the exhibition floor, and by opening the maintenance door, the water-absorbing polymer material can be freely placed inside the moisture box. It can be taken in and out. This not only reliably prevents moisture supply water from overflowing onto the exhibition floor, but also prevents water-containing water-absorbing polymer materials from accidentally dropping onto valuable exhibits when replacing them, etc. Not at all. Therefore, maintenance can be performed quickly and safely. Further, in this manner, the water-absorbing polymer material can be replaced, water can be replenished, etc. without significantly disturbing the humidity-controlled atmosphere in the exhibition space.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

First, the overall structure of the display case (peek case) will be outlined with reference to Figures 3 and 4.

As shown in Fig. 3, this display case consists of a case body 1 and an upper lid 2. It is divided into section 5. An upper lid 2 covers an exhibition space 6 formed inside the exhibition section 5 from the front. The upper lid 2 is made by rigidly bonding transparent glass plates 2a, 2b, and 2b together, and fixing the periphery to the display section 5 so that the lid cannot be opened or closed.

The case body 1 is constructed of a lower frame 7 and an upper frame 8 with struts 9, 9 erected at the four corners, and further has an upper frame 10 constructed on the upper part of the back side. Then, around these hollow frame bodies, there is a front panel 1
1. Side panels 12a, 12b and rear panels 13a, 13b are attached. Among these, the front panel 11 that covers the front surface of the base portion 4 has its lower end hinged to the lower frame 7 so that it can be opened and closed toward the front as shown by arrow a in the figure. That is, the base portion 4
The space can be opened to the outside by opening the front panel 11.

Further, an inner frame 14 is fixedly installed at a height position corresponding to the groove 3 in the case body 1.
The periphery of an exhibition floor 15 that can be raised and lowered is brought into contact with the lower surface of the display panel 4 via a seal 16. In other words, exhibition floor 15
can be raised and lowered in the space within the base section 4 in the direction of arrow b in the figure by means of an elevating mechanism 17 that supports it from below.In the lowered position, the front panel 11 is opened and the exhibition section X is placed above it. in and out of the
In the raised position, it comes into contact with the inner frame 14 to airtightly close off the upper exhibition space 6. A pipe 19 that forms a vent 18 that communicates the exhibition space 6 with the space of the base section 4 is installed through the front part of the exhibition floor 15.
A humidification box 20, which will be described later, is attached below it. That is, the inside of this humidity box 20 is communicated with the exhibition space 6 via the ventilation hole 18. Note that fabric-covered decorative panels are attached to the top plate 21 of the exhibition floor 15 and the back plate 22 of the exhibition space 6.

In addition, 23 in FIG. 4 is a lighting box with a maintenance door 23a installed in the front part of the exhibition floor 15, and a front light 24 and a reflector 2 installed inside.
5 through the hot-cut glass 26 at the upper rear,
The exhibition space 6 is illuminated from the front. Reference numeral 27 denotes a maintenance door, which is equipped with a rear light 28 on the inside that illuminates the exhibition space 6 from behind through a cover 29, and is hinged to the top surface of the exhibition section 5 so that it can be opened and closed independently as shown by arrow c in the figure. Furthermore, 30 indicates casters attached to the lower frame 7.

The humidifier according to the present invention will now be described with reference to FIGS. 1 and 2.

As mentioned above, the exhibition floor 15 is provided with a ventilation hole 18, and a humidity box 20 is integrally attached to the exhibition floor 15 below the ventilation hole 18. This humidity supply box 20 has a lower surface side formed of a ventilation member 31 such as a mesh, and cool air flows into the box through the ventilation member 31 from the space of the base portion 4 which is open below, and further, the ventilation opening 18 Air is supplied to the interior of the exhibition space 6 through. As shown in FIG. 2, the humidity box 20 attached to the exhibition floor 15 has a maintenance door 20a hinged to its front side that can be opened and closed. A sheet-shaped moisture absorbing material 32 is freely inserted and removed on top of the ventilation member 31 as shown by the arrow d in the figure.

This moisture absorbing material 32 uses a moistened water-absorbing polymeric material according to the present invention. That is, natural or synthetic polymeric materials with high water absorption are used, and specific examples of their compositions include natural rubber,
It is made from a blend of ingredients such as vegetable rubber, hydrogel, polysaccharides, cellulose, starch, and glycogen. And this water-absorbing polymer material 3
2 is set in the humidity box 20 after soaking in water and making it sufficiently moist.
It impregnates and retains a certain amount of moisture, and continuously emits water vapor from the surface without dripping. Incidentally, the water-absorbing polymer material 32 can be a material conventionally used as a coolant for a welding heat-affected zone.

Now, in the case of an exhibition case equipped with a humidifying device configured as described above, cold air entering the space of the base section 4 will flow into the closed exhibition space 6 on the exhibition floor 15 as shown by the arrow e in the figure. The water comes into contact with the water-absorbing polymeric material 32 in the humidifier box 20 and is sufficiently humidified, and then flows through the vent hole 18. Therefore, a necessary high humidity atmosphere can be created for the exhibit X displayed on the exhibition floor 15. At this time, if the water-absorbing polymeric material 32 is sufficiently moistened in advance, it will be impregnated with moisture at a very high volume ratio, and the airflow from below will actively evaporate water vapor from the surface. Unlike the case where water is stored in a container where water vapor is released only from one side, moisture can evaporate from five or all sides, so it exhibits a superior moisturizing effect compared to when using a water receptacle. Become something to do.

In this device, the humidity box 2
0 is hidden under the floor of the exhibition floor 15 and is completely hidden from the viewers, and at the same time, since the water-absorbing polymer material 32 absorbs water without dripping, there have been reports of water accidentally flowing out due to vibrations etc. The biggest advantage is that it can eliminate problems.

If necessary, the water-absorbing polymer material 32 can be replaced easily by opening the front panel 11 and opening the maintenance door 20a exposed at the front. That is, according to such a configuration, after opening the front panel 11,
By opening this maintenance door 20a,
A water-absorbing polymer material 32 is placed inside the moisture box 20.
can be taken out and put in freely. Therefore,
As mentioned above, it is possible not only to reliably prevent moisture supply water from overflowing onto the exhibition floor 15, but also to prevent water-containing water-absorbing polymer material 32 from accidentally falling onto valuable exhibits when replacing it, etc. There is no fear that it will fall. Therefore, it is possible to obtain the effect that maintenance can be performed quickly and safely.

[Effects of the invention] As explained above, the humidifier of the invention has the following effects:
The exhibition space that houses the exhibits is made to absorb moisture using moistened water-absorbing polymer materials.
It is possible to reliably prevent troubles such as humidifying water flowing out onto the exhibition floor while ensuring the necessary humidifying effect. Moreover, in the device of the present invention, by opening the space in the base portion to the outside and then opening the maintenance door, the water-absorbing polymer material can be freely taken in and out of the moisture box. This not only reliably prevents moisture-supplying water from overflowing onto the exhibition floor as mentioned above, but also prevents water-absorbing polymer materials containing moisture from being accidentally spilled onto valuable exhibits when replacing them. There is no fear of it falling. Therefore, maintenance can be performed quickly and safely. In addition, with this configuration, the water-absorbing polymer material can be replaced or water can be replenished without significantly changing the humidity-controlled atmosphere in the exhibition space, so the humidity in the exhibition space can be temporarily reduced during maintenance. It is also possible to effectively prevent problems such as sudden changes in performance and adverse effects on exhibits.
