Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to bran having hygroscopic properties.

(Conventional technology) For example, an apartment building made of reinforced concrete has a strong building structure and high airtightness in terms of soundproofing and fireproofing.
When each room is divided into small sections, it is difficult for indoor air to circulate and the air tends to stagnate, resulting in high indoor humidity and mold growth, both during the rainy season and winter. . Particularly in the winter, the walls on the north and both gable sides of apartment complexes are easily cooled and often cause condensation. There is almost no air convection in closed spaces such as insertion rooms and storage rooms, and the existence of the closet creates a heat-insulating layer, which keeps the surface temperature of the wall low, and the humidity inside the closet remains indoors. Condensation may occur as the temperature is high. Due to this phenomenon, there is a problem that walls, bedding, etc. are contaminated with mold. In order to solve this problem, in the past, for example, in the case of a closet, the sliding door was left open to ventilate the inside of the closet, thereby promoting air convection and removal of moisture inside the closet. It was hot.

(Problem that the invention aims to solve) However, the above method is ineffective unless the sliding door is left open, so in daily life it is impossible to leave it open all the time, and furthermore, the effect disappears if the sliding door is closed. However, the ventilation effect is not sustainable, and leaving the sliding door open all the time is inconvenient in daily life, making it difficult to enforce it on a daily basis.

(Means for solving the problem) The bran 1 of the present invention has a base aggregate 2 in the hollow interior.
Through holes 2a, 3 are arranged to communicate each space 1a partitioned by the base aggregate.
A is provided in large numbers through the base aggregate, a desiccant 4 is stored in the space, a moisture absorbing surface 5 is formed on at least one side of the fusuma, and an inner layer is formed on both the upper and lower sides of the side of the fusuma, that is, one side or both sides. Upper and lower ventilation holes 7a and 7b are formed, respectively, to communicate with each other.

(Function) Air passes through the inside of the sliding door 1 from the lower ventilation opening 7b and is discharged from the upper ventilation opening 7a to the outside of the sliding door, that is, into the room.
Moisture on the side is sucked into the fusuma 1 and absorbed by the desiccant 4. Depending on the type of desiccant used,
The absorbed moisture will be
The desiccant releases the absorbed moisture and discharges this moisture into the room by suctioning the air that enters through the vent.

(Example) An example of the present invention will be described below based on the drawings.

In the hollow interior of the sliding door 1, vertical ribs 2 and flat ribs 3, which are base aggregates combined in a lattice pattern, are arranged. A large number of spaces 1a partitioned by vertical bones 2 and flat bones 3 are
The vertical bones 2 and the flat bones 3 are in communication with each other through circular through holes 2a and 3a that are formed through the longitudinal bones 2 and the flat bones 3 in the thickness direction, respectively. A desiccant 4 is stored in all of the space 1a or in all but the upper and lower sides.

The inner surface of the sliding door 1 facing the push-in side (the left side in FIG. 1) is a moisture-absorbing surface 5, and this moisture-absorbing surface has a large number of small holes 5a that communicate with the space 1a. The surface is covered with cloth 6. Furthermore, four pairs of slit-shaped upper ventilation holes 7a and four lower ventilation holes 7b are provided on both upper and lower sides of the outer surface of the sliding door 1 on the room side in the width direction of the sliding door. Therefore, the air that has entered the lower vent 7b can exit the upper vent 7a through the space 1a of the sliding door 1.

Next, moisture absorption and ventilation inside the closet will be explained.

Indoor air enters the space 1a inside the sliding door 1 from the lower vent 7b as shown by the arrow in Fig. 1, passes through the vents 2a and 3a to the next space, and eventually reaches the upper vent 7a, where it enters the room. leaks to. Air is fusuma 1
In the process of passing through the interior, the moisture and air near the moisture absorbing surface 5 inside the closet are sucked into the sliding door through the small holes 5a of the moisture absorbing surface, where the moisture is absorbed by the desiccant, and as a result, the moisture inside the closet is reduced. Dropping and air convection are promoted.

Humidity is controlled by changing the amount of desiccant 4.

In the above example, 1200 g of silica gel type B (trade name) was used as the desiccant. This type of desiccant is
Has moisture absorption and desorption properties. In other words, this desiccant has the adsorption capacity to absorb 50% of the mass of the desiccant when the relative humidity is 80%, and conversely when the relative humidity is 60%.
When the water absorption rate decreases from 50% to 20%, the desiccant releases water equivalent to 30% of the water absorbed by the desiccant. As described above, this desiccant has a high water absorption rate especially at high humidity, and has a circulation function that releases absorbed moisture when the relative humidity decreases, so there is no need to replace the desiccant. Also, the amount of this type of desiccant to be used will be explained. Although it is very difficult to estimate the amount of water vapor generated indoors, it is possible to estimate the amount of water vapor generated per day using the standard quantification of the amount of water vapor generated during the daily activities of individual residents. investigated. Estimating the amount of moisture in the human body for two couples based on sleeping in a Japanese-style room, it is 35 g/h for adults x bedtime (gh) x 2 people =
The amount of steam generated is 560g/day. Other moisture,
The influence of humidity caused by heating and other daily activities in the living room shall be ignored.

Some of this water vapor becomes condensation water on the glass surface,
Bedding that absorbs moisture is dried outside, and the increased humidity inside the room is discharged outdoors through natural ventilation, etc., so the residual moisture in the bedding and other closets is 10% of the amount of water vapor, or 56g. /day was set. Based on this, 1200g of desiccant is sufficient for the bran.

The sliding door 1 is not necessarily limited to being used as a closet, and although the upper and lower ventilation holes 7a and 7b are provided on the outer surface of the sliding door, that is, on the same side as in the above example, they may also be provided on the inner and outer surfaces, that is, on the upper and lower sides of both sides. good.
Furthermore, moisture absorption surfaces 5 may be provided on both sides of the sliding door.

(Effects of the invention) As explained above, according to the invention, it is possible to promote moisture absorption and air convection in spaces such as insertion spaces, prevent the growth of mold on walls and bedding, and eliminate the need for fusuma as in the past. The trouble of opening and closing can be omitted.
