Description

  The present invention relates to a humidity control panel used as an interior building material for a house.

In recent years, due to the progress of high thermal insulation and high airtightness in houses, the occurrence of condensation, mold, mites, etc. due to this has become a problem, and humidity control in the house is the next issue .
Therefore, a humidity control panel having a humidity control function that has been conventionally used for interior building materials of a residence has been proposed.
For example, Patent Document 1 below proposes a panel in which charcoal or the like is packed in a partition partitioned by a partition plate, and a breathable covering sheet is attached to the front and back surfaces.
On the other hand, Patent Document 2 below proposes a wall structure in which a ventilation layer is provided between a ventilation inner wall material of a building and an inner surface of a wall surface heat insulating member, and an adsorbent is incorporated in the ventilation layer. In this device, an exhaust fan is attached to the wall surface of the attic, and the exhaust fan allows outside air or room air to pass through the ventilation layer through the opening provided in the base or the room, and to pass through the attic. It is configured to exhaust outside.

Japanese Patent Laid-Open No. 10-8633 (see FIG. 1) Japanese Patent Laid-Open No. 2001-140368 (see FIG. 1)

The conventional humidity control panel as described in Patent Document 1 is configured to absorb and release moisture using natural convection of air in the indoor space, and efficiently and actively condition the air in the indoor space. It was difficult.
Moreover, in what was described in the said patent document 2, although it is set as the structure which takes in air actively to a ventilation layer using an exhaust fan etc., it is concerned with the whole structure of a building, There was a problem that the whole structure was complicated.

  This invention is made | formed in view of the said situation, and it aims at providing the humidity control panel which can humidity-control the air of indoor space efficiently.

  The humidity control panel according to the present invention includes a first air passage provided along the back side of the panel internal space, a second air passage provided along the front surface side of the panel internal space, and the panel An intake port provided at one end of the panel and communicated with any one of the air flow paths, an exhaust port provided at the other end of the panel and communicated with any one of the air flow paths, a blowing means, the first air flow path, and the The humidity control material is housed in a large number of housing cells provided between the second air passage and divided in multiple stages in the air blowing direction of both air passages, and air is communicated from one air passage to the other air passage. The humidity control material holding layer configured as described above and the air flow path communicating with the exhaust port by meandering the air introduced from the air intake port so as to alternately flow through both air flow paths through the humidity control material holding layer Airflow changing means configured to lead to And butterflies.

With this configuration, the indoor air that is forcibly taken in from the intake port by the air blowing unit is adjusted by the air flow changing unit via the air passage (the first air passage or the second air passage) communicating with the air inlet. The two air passages meander so as to alternately flow through the wet material holding layer, and are led out to the air passage communicating with the exhaust port. At this time, the indoor air is conditioned (dehumidified or humidified) when passing through the humidity-controlling material holding layer configured to allow air to pass from one blast path to the other blast path, and is conditioned from the exhaust port. The exhausted air is exhausted. Therefore, for example, compared with the case where the air passage is provided only on one of the front side and the back side of the inner space of the panel and the humidity control material holding layer is provided on the other side, the air is more efficiently supplied to the humidity control material It can be made to contact and moisture absorption / release property can be improved efficiently.
Moreover, since the humidity control material is stored in the storage cell, the humidity control material can be efficiently stored in the humidity control material holding layer.
That is, since the humidity control material is stored in the storage cell that is partitioned in multiple stages in the air flow direction of the air passage, compared to the case where the inside of the humidity control panel is configured in one space, the upstream side of the air passage is downstream. Thus, the humidity control material can be efficiently accommodated.
Further, since the humidity control material can be stored by being partitioned into the storage cells, the storage amount of the humidity control material can be adjusted for each storage cell.

In the present invention, the air flow changing means may be configured by a plurality of air passage blocking portions provided alternately in the middle of the first air passage and the second air passage.
In this case, since the air passage blockers are alternately provided in the middle of the first air passage and the second air passage, for example, the air flow through the first air passage is blocked by the air passage blocker. The air flows to the second air passage through the humidity conditioning material holding layer, and the air flow through the second air passage is blocked by the air passage blocking portion, and again passes through the humidity conditioning material holding layer to the first air passage. It flows to. As described above, it is possible to realize the meandering of the airflow by alternately flowing through the two air passages with a simple configuration.

In the present invention, the humidity control material may be accommodated so that a gap is formed above each of the accommodation cells.
In this way, if the humidity control material is stored so that a gap is formed above each storage cell, the air passing through the humidity control material holding layer can be easily passed above the storage cell formed. Since the pressure loss can be reduced, the air permeability of the humidity control material holding layer can be improved.
The gap formed here is not a gap formed between the granular humidity control materials filled in the containing cells, but a gap formed above each containing cell space.

  Since the humidity control panel according to the present invention is configured as described above, the air in the indoor space can be efficiently conditioned.

It is a schematic longitudinal cross-sectional view which shows typically one Embodiment of the humidity control panel which concerns on this invention. It is a schematic longitudinal cross-sectional view which shows typically the modification of a synchronous moisture panel.

A path 5 is formed.

  The size of the humidity control panel 1 can be set as appropriate according to the installation location or the like. However, when the vertical panel is installed as a wall panel as in this embodiment, the length (height The length may be about 1500 mm to 2000 mm, the width is about 200 mm to 500 mm, and the thickness is about 30 mm to 60 mm. In the present embodiment, the humidity control panel 1 has a length (height) of about 1800 mm, a width of about 300 mm, and a thickness of about 45 mm.

The panel main body 9 composed of the front plate portion 9a, the back plate portion 9b, and the pair of side plate portions 9c, 9c may be formed integrally with a steel plate or the like. You may make it comprise.
Moreover, you may make it stick surface cosmetics, such as a decorative sheet, wallpaper, and a veneering board, to the surface of the front board part 9a used as the site | part exposed to the indoor space of the outer peripheral surface of this panel main body 9. FIG.
Furthermore, the ratio of the thickness dimension (thickness dimension along the thickness direction of the humidity control panel 1) of the front side air passage 6, the humidity control material holding layer 10 and the back side air passage 5 is 1: 2: 1 to 1. It may be about 1: 3: 1.

The humidity control material holding layer 10 opens on both sides in the thickness direction of the humidity control panel 1, and is divided into multiple stages in the vertical direction of the panel body 9 (the same direction as the blowing direction of both the air flow paths 5 and 6) and the width direction. Further, a core material composed of an assembly of a large number of hollow cylindrical accommodation cells 11 is used as a core material, and the upper and lower portions and both side portions of the outer periphery are the top plate portion and bottom plate portion of the panel body 9, and both side plate portions 9c and 9c. Etc. are fixed.
The accommodation cell 11 accommodates a humidity control material 12 having moisture absorption / release properties.
Moreover, the front surface side and back surface side of the core material which forms this accommodation cell 11 are opened.
In the figure, reference numeral 11a denotes an opening 11a of the containing cell 11, and breathable films 13 and 13 having air permeability and moisture permeability are respectively attached to the opening 11a.

  The core material for forming the storage cell 11 may be formed by stacking and adhering paper materials such as corrugated cardboard or kraft paper with an adhesive. Further, such a paper material may be further impregnated with a reinforcing resin such as an epoxy resin. In addition, it may be made of a metal material such as an aluminum material or a synthetic resin material such as a hard polyvinyl chloride resin or a polypropylene resin.

The cell shape of the accommodating cell 11 is a honeycomb-like honeycomb shape, a square shape, a rhombus shape, a cylindrical shape as defined in JIS A6931, a rib shape in which ribs are continuous in parallel, or a “<” shape. The origami shape may be a continuous origami shape.
The cell size (cell width) of the containing cell 11 may be about 10 mm to about 30 mm. In the present embodiment, the honeycomb-shaped accommodation cell 11 having a cell size of about 20 mm is made of a paperboard having a thickness of about 0.3 mm with little or no air permeability (non-breathable material).

The humidity control material 12 stored in the storage cell 11 is in the form of powder, charcoal such as charcoal and bamboo charcoal, clay such as talc, zeolite, diatomaceous earth, silica gel (preferably B-type), montmorillonite and sepiolite. Examples thereof include inorganic substances such as minerals, alumina, and silica. Or it is good also as a polymer moisture absorption / release material which has a reversible moisture absorption function and a moisture release function. In the present embodiment, silica gel is used as the humidity control material 12.
The particle diameter of the humidity control material 12 may be about 1.0 mm to about 6.0 mm from the viewpoint of humidity control and air permeability. As the particle size of the humidity control material 12 decreases, the surface area of the humidity control material accommodated per unit volume increases and the humidity control performance improves, but the gap between the humidity control materials tends to decrease and the air permeability tends to be hindered. On the other hand, as the particle size increases, the air permeability improves, but the humidity control property tends to be inhibited. In the present embodiment, the humidity control material 12 having an average particle size of about 2.0 mm is employed.
In addition, you may use the said various humidity control materials 12 in combination of 2 or more types. Moreover, it is not restricted to a particulate-form humidity control material, It is good also as a flaky shape or a short fiber piece shape.

It is good also as a material. Alternatively, a net-like member obtained by processing a synthetic resin material or a metal material into a mesh shape so as to form a ventilation hole, or a sheet member having a large number of ventilation holes may be used.
The cloth-like member may be a cross sheet in which fibers are plain woven, one knitted by various woven forms, or a non-woven fabric.
Such a gas permeable membrane 13 may be configured to be able to hold the humidity control material 12 without passing through, depending on the particle size of the humidity control material 12 described above.

For example, the humidity control material holding layer 10 having the above-described configuration is obtained by attaching the air-permeable film 13 to one side of the core material, and then supplying the humidity control material 12 to each containing cell 11 from the other side of the core material. May be accommodated, and the gas permeable membrane 13 may be attached to the other side to form a plate shape. In the present embodiment, the humidity control material holding layer 10 has a length (height) of about 1700 mm, a width of about 290 mm, a thickness of about 25 mm, and a total of about 6.0 kg of the humidity control material 12 in each containing cell 11. It is filled relatively densely so that no voids are formed therein.
By having such a large number of storage cells 11, the humidity control material 12 can be efficiently stored in the humidity control material holding layer 10. In particular, when the humidity control panel 1 is applied as a vertical wall panel installed so that the intake port 2 and the exhaust port 3 are vertically positioned as in the present embodiment, the inside of the humidity control panel is Compared with the case where it is configured in one space, the humidity control material can be efficiently accommodated from the upstream side to the downstream side of the air flow paths 5 and 6, and the humidity control material 12 is under the humidity control panel 1 by its own weight. It is possible to reduce the vertical deviation such that the humidity conditioning material 12 is filled only on the side.

The lower outer portion 20 connected to the lower side of the panel main body 9 has a casing shape for housing the cross flow fan 4 constituting the air blowing means, and a plurality of slit-like intake ports 2 are formed on the surface side thereof. A plurality of lattice members 21 are provided.

Moreover, you may make it provide the guide member which changes the airflow direction of the air ventilated toward the exhaust port 3 from the outlet port 8. FIG.

In the middle of the respective paths in the back surface side air passage 5 and the front surface side air passage 6, air passage blockers 14 and 15 constituting airflow changing means are provided at intervals. The air passage blocking portions 14 and 15 are configured by plates made of foamed polystyrene and the like, and the number of the installed air passages is not particularly limited, but in the present embodiment, a total of two pieces are provided at two locations on the back side air passage 5. An example is shown in which the air passage blocking section 14 is provided and a total of three air passage blocking sections 15 are provided at three locations on the front-side air passage 6.
The width dimensions (dimensions along the panel thickness direction) of these air passage blocking sections 14 and 15 are set to be approximately the same as the air path widths of both the air blowing paths 5 and 6, and the air passage blocking sections 14 and 15 hold the humidity control material. It arrange | positions between the accommodation cell 11 and the accommodation cell 11 so that the flow of the air which flows into the layer 10 may not be disturbed. The air passage blocking portions 14 and 15 are provided so as to be staggered so that the arrangement positions do not overlap when viewed in cross section as shown in FIG. 6 is configured to flow alternately.
These air passage blocking portions 14 and 15 may be fixed to the front surface side and the back surface side of the humidity control material holding layer 10 with an adhesive or the like, or fixed to both side plate portions 9c and 9c of the panel body 9. You may do it.

Next, the flow of air will be described with reference to arrows 40 to 48 in FIG.
In the humidity control panel 1 configured as described above, indoor air is taken in from the air intake 2 when the operation unit is operated to start the cross flow fan 4 (see arrow 40).
This taken-in air is introduced into the back surface side air passage 5 through the introduction port 7 communicating with the back surface side air passage 5 (see arrow 41), and is blown upward by the cross flow fan 4 (see arrow 42). . The air that has passed through the humidity-controlling material holding layer 10 and has flowed to the front-side air passage 6 (see arrow 43) passes through and contacts the humidity-controlling material 12 and the air-permeable membrane 13, and the air is conditioned at this time. The
Further, the air that flows upward and contacts the air passage block 14 is blocked by the air passage block 14 and loses its upward direction, and is forced to the air passage 6 through the humidity control material holding layer 10. Flow (see arrow 44).
Then, the air that flows upward through the front-side air passage 6 and contacts the air passage block 15 is blocked by the air passage block 15 and loses its place to go upward, and is forced through the humidity control material holding layer 10 again. It flows to the back surface side air passage 5 (see arrow 45).
Thus, the air taken in from the intake port 2 alternately passes through both air passages via the humidity control material holding layer by the air passage blockers 14 and 15 provided with a space between the air passages 5 and 6. The air can be efficiently brought into contact with the humidity control material 12 while flowing and meandering.
Finally, the air passing through the front side air passage 6 is led out to the rear side air passage 5 communicating with the exhaust port 3 by the air passage block 15 provided on the downstream side near the exhaust port 3 (arrow). 46). Then, the air flows from the back surface side air passage 5 to the exhaust port 3 through the outlet 8 (see arrow 47), and the air that has been sufficiently conditioned from the exhaust port 3 toward the indoor space is exhausted.
Although not described here, it goes without saying that even when the cross flow fan 4 is turned off, the air flowing into the air blowing paths 5 and 6 passes through the humidity control material holding layer 10 and the humidity is adjusted.

  As described above, according to the humidity control panel 1 according to the present embodiment, the air can be efficiently conditioned by forcibly circulating the indoor air as described above. In particular, as in the present embodiment, if the air intake port 2 is at the lower end side and the air exhaust port 3 is at the upper end side and installed vertically on the wall surface or indoor space, it is positioned near the indoor floor surface. The air sucked from the lower intake port 2 can be discharged from the upper exhaust port 3 located near the ceiling of the room, so that the indoor air can be circulated more efficiently. Can be conditioned more efficiently.

  In addition, the indoor air that is forcibly taken in from the air inlet by the cross flow fan 4 passes through the air passage (here, the rear air passage 5) that communicates with the air inlet 2 and is controlled by the air passage shielding plates 14 and 15. The air passages 5 and 6 meander alternately through the holding layer 10 and can be led out to the air passage (here, the rear air passage 5) communicating with the exhaust port 3. Therefore, for example, compared with the case where the air passage is provided only on one of the front side and the back side of the interior space of the panel and the humidity control material holding layer is provided on the other side, the air is more efficiently supplied to the humidity control material 12. It can be made to contact and moisture absorption / release property can be improved efficiently.

In the above embodiment shown in FIG. 1, the example in which the humidity control material 12 is accommodated relatively densely so that no gap is formed in each accommodation cell 11 has been described. However, as shown in FIG. 2, in the upper space of each accommodation cell 11. You may make it accommodate so that the space | gap of about 10%-50% may be formed.
Thus, if it accommodates so that a space | gap may be formed above each accommodation cell 11, space will be formed above the accommodation cell 11, and air will pass there through (refer arrow 50). The pressure loss of the air which passes the material 12 moisture-conditioning material holding layer 10 can be reduced, and the air permeability of the humidity-conditioning material holding layer 10 can be improved.

In addition, although the humidity control panel 1 attached to the existing wall surface 60 was demonstrated, it is not limited to this, It is one in order to become the same surface as the surface of another wall surface material or another humidity control panel. The part may be attached so as to be embedded inside the wall, or as a partition panel, an appropriate support member or the like may be provided at the lower end or the like, and installed in the indoor space.
Moreover, although the said embodiment demonstrated the example in which the inlet which connects an inlet port and the back surface side ventilation path of a panel main body was formed near the back surface side of the top-plate part of a lower outer shell part, You may comprise so that an inlet port may be formed and an inlet port and the surface side ventilation path of a panel main body may communicate. Similarly, in the above-described embodiment, an example in which the outlet port that connects the back surface side air passage and the exhaust port of the panel main body is formed near the back surface side of the bottom plate portion of the upper outer shell portion has been described. May be formed so that the front side air passage and the exhaust port of the panel body communicate with each other.
Further, the installation position of the air passage blocking unit constituting the air flow changing means is not limited to the example in the figure. In short, it does not disturb the air flow, but the air taken in from the intake port is inserted through the storage cells. It only has to be provided so as to flow while meandering between the air passages and to the air passage communicating with the exhaust port.

In the above embodiment, a vertically long and flat rectangular panel is illustrated as the humidity control panel, but a horizontally long and flat rectangular panel may be used, and each of the exhaust port and the intake port may be on the opposite side to the illustrated example. You may make it provide.
In addition, although an example in which the intake and exhaust ports constituting the pair of ventilation openings opened on the surface of the humidity control panel are separated from each other in the up and down direction is illustrated, Also good. That is, the humidity control panel may be installed horizontally as a horizontal panel.

Further, in the above-described embodiment, an example in which a crossflow fan is provided in the lower outer portion as a blowing means for blowing air may be provided in the upper outer portion, or at least one of them. You may make it provide in the middle site | part of one ventilation path.
And it is not restricted to a cross flow fan, You may make it provide a sirocco fan, an axial flow fan, etc. as a ventilation means.
