Also, in the case of a wall, objects often collide,
In order to secure impact resistance, it is necessary to reinforce the rear surface of the humidity control panel with studs, which has the drawback of poor workability.
And when the reinforcement by studs is added, if the studs are used in a high humidity state for a long period of time or the back space part of the humidity control panel is impaired, the studs will be corroded or deformed due to dew condensation, A new problem has arisen, such as contamination bleeding onto the surface of the humidity control panel.

The cross section of the humidity control unit (A) is, for example, as shown in FIG. 1, and the casing (3) used for this has a box-like shape with an open lower surface, and the humidity control panel is provided in the lower opening.
(B) is installed, and the moisture removal space (2) is provided on the back of the humidity control panel (B).
Are formed. Two duct connecting holes (4) are formed in at least one of the side surface and the upper surface of the casing (3). Further, a C-shaped bar (11) serving as a suspension portion (5) is installed on both sides of the upper surface of the casing (3), and an insertion hole (12) for inserting the suspension bolt (13) is formed. It is set up. A brim-shaped ceiling finishing material (9) around the entire circumference of the casing (3)

When turned on, low-humidity outside air is sucked through the outside air suction duct (6a), and then flows through the back surface moisture removal space (2). Here, the moisture in the back surface moisture removal space (2) is deprived of the moisture, flows into the air exhaust duct (6b), and is discharged to the outside. This allows
Moisture in the back surface moisture removal space (2) is continuously discharged to the outside. As a result, the humidity in the space (2) gradually decreases, and the moisture in the humidity control panel (B) causes the moisture in the humidity control panel (B) to quickly move to the back surface. As a result, the moisture content on the indoor side surface of the humidity control panel (B) gradually decreases, and the moisture absorbing filler works to continuously suck in the indoor moisture, and the indoor humidity converges toward the outdoor humidity. It gradually decreases in the form of doing.

Since the humidity control panel (B) is a part of the ceiling surface, unlike the wall surface, the panel is not blocked by obstacles, and a predetermined humidity control area is always secured. It can be done and there is no such thing as the humidity control performance being deteriorated. Also, since there are almost no objects that come into contact with the ceiling surface, there is no need to provide studs to ensure impact resistance like wall surfaces, and the strength of the panel itself is not so required. , You just need to hang it securely. Therefore, the structure is simple, and the cost can be reduced, and the problems (= deformability and contamination) when the studs are provided as described in the conventional example can be solved. Furthermore, since the installation place is the ceiling surface, a sufficient space can be secured unlike the case of a wall, and a sufficient space for the rear space part (2) and a duct installation space can be secured.

[0018]

The humidity control unit of the present invention comprises an inorganic plate to which a hygroscopic filler is internally added, a casing to which the inorganic plate is attached, and which forms a space on the back surface of the inorganic plate, and the casing. Since it is composed of at least two duct connecting holes formed in the housing and a suspending portion provided in the casing, the humidity control unit with the inorganic plate facing downward by the suspending bolt suspended from the ceiling body. Can be installed on the ceiling. Therefore, unlike the conventional case where a humidity control unit is installed on a wall, a sufficient space can be secured in the space behind the ceiling between the ceiling surface and the ceiling skeleton, and the casing can be made to have a sufficient size. A sufficient space can be secured in the back space of the plate, and the duct for connecting to the humidity control unit can be thick enough so that ventilation and moisture removal can be performed without difficulty. .
In addition, since there is a sufficient space in the space behind the ceiling between the ceiling surface and the ceiling frame, there is an advantage that the construction is easy.

Furthermore, since the humidity control unit of the present invention can be installed on the ceiling surface, unlike the case where it is installed on the wall surface, there is no obstacle installed in front of the inorganic plate, and the humidity control is as designed. The area can be secured at all times. In addition, because it is installed on the ceiling in this way, it is unlikely that something will come into contact with the inorganic plate, and the strength of the inorganic plate itself is not so required, so the strength of the inorganic plate is to be suspended. It is as strong as possible.

Furthermore, since the ventilation fan is installed in the duct connected to the casing of the humidity control unit installed on the ceiling, the dry outside air is sent to the back space by operating the ventilation fan, and the height of the space is increased. Humid air can be discharged to the outside through an exhaust duct, and indoor humidity can be continuously absorbed from the ceiling surface.

Since a plurality of humidity control units can be installed in parallel, the corresponding duct connection holes can be connected by the connection tube, and the ducts can be connected to at least two duct connection holes located outward. There is also an advantage that the humidity control unit can be freely laid out according to the size of the room.
