Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a structure for adjusting the temperature in a room of a building to an appropriate level by ventilation and eliminating air pollution in the room.

[0002]

[Prior art]

 Heretofore, as a method of controlling the indoor temperature, as disclosed in Japanese Patent Application Laid-Open No. 9-60138, the under-floor space and the under-ceiling space are ventilated through a communication space in the wall, and the ventilation is performed by a damper. Building structures have been proposed to control the airflow in the road to keep the indoor temperature at an appropriate temperature.

In this structure, the temperature of the air in the outer wall surface heated by the sun rises, and the high-temperature air flows upstream from the underfloor space to the underfloor space. In summer, in order to prevent the indoor temperature from rising, the high heat that rises and collects in the space behind the ceiling is opened to the outside of the room by opening the damper. At the same time, the low-temperature air in the underfloor space is sucked in from the open damper so that the communication space inside the wall and the space above the ceiling can be cooled.

In winter, in order to prevent the indoor temperature from dropping, high damping air that rises and collects in the space behind the ceiling is not closed and discharged to the outside without closing the damper in the underfloor space. A method is adopted in which warm air is circulated so as not to allow outside air at temperatures to enter.

Japanese Patent Application Laid-Open No. 2001-140368 discloses that harmful gas and moisture in a room pass through a permeable inner wall surface and are taken into a ventilation layer in the wall, and the harmful gas and moisture are incorporated in the ventilation layer. A ventilation control device has been proposed in which the air is purified by passing through the adsorbed material, and the purified air is discharged from the exhaust fan to the outside of the room or returned to the room.

In this method, although the adsorbent can be regenerated by passing outside air, it is difficult to remove the harmful gas once adsorbed, and the dirty air in the room is not adsorbed in the wall. It accumulates in the material and the purification function decreases over time. There is also a risk that air that is not completely purified and contaminated with harmful substances will return to the room.

[0007]

[Problems to be solved by the invention]

 The present invention has been made in view of the above-mentioned circumstances, and in order to prevent the temperature inside the building from rising by discharging the solar heat in the summer, and circulating the air heated by the solar heat in the winter to warm the room. Another object of the present invention is to provide an indoor introduction structure for purified air for purifying external air, taking it into a room, and replacing the air containing formaldehyde and the like generated in the room with fresh air for purification.

[0008]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the present invention provides a space 3 between the outer peripheral wall 1 and the indoor peripheral wall 2 of the house, which communicates with the underfloor space 4 and the space above the ceiling 5. The underfloor space 4 and the under-ceiling space 5 are provided with dampers 7a, 7b, 7c with vents 6a, 6b for controlling the intake and exhaust of outside air, and at least one of the spaces 3, 4, 5 is provided with a suction plate. Distribute 8. Further, a blower 9 for sending the air in the space 5 above the ceiling and / or the space 3 in the wall to the room is provided on the space 5 above the ceiling and / or the peripheral wall surface 2 of the room. The purified air is introduced into the room by purifying the outdoor air with the adsorbing plate 8 so as to be introduced into the room.

Further, in the above configuration, the adsorbing plate 8 is made of a porous adsorbent of a carbide type such as activated carbon or an inorganic type such as Kanuma earth.

[0010] Further, in the above configuration, the in-wall space 3 is formed by interposing a member 10 between the inner surface of the outer wall 1 and the inner surface of the outer wall material.

[0011]

[Embodiment of the invention]

 An embodiment of the present invention will be described below based on an embodiment of the drawings.

As shown in FIG. 1, the indoor air introducing structure of the purified air according to the present invention is provided between a peripheral wall 1 of a house and a peripheral wall 2 of a house, facing a space 4 under the floor and a space 5 above the ceiling. An in-wall space 3 is provided through an opening 3a to the space behind the ceiling and an opening 3b to the underfloor space in the wall.

The underfloor space 4 and the underfloor space 5 are provided with vents 6a and 6b having dampers 7a, 7b and 7c on the underfloor side and under the eaves for controlling the intake and exhaust of outside air. Then, suction plates 8 are attached to the spaces 3, 4, and 5, respectively. Further, a blower 9 for sending the air in the space 5 above the ceiling and the space 3 in the wall to the room is provided in the space 5 above the ceiling and the inner peripheral wall 2 so that the air outside the room can be purified by the suction plate 8 and introduced into the room. To

The adsorbing plate 8 has a size similar to that of a gypsum board or a plywood having an inner wall material made of a carbide-based porous adsorbent such as charcoal or activated carbon, or an inorganic porous adsorbent such as Kanuma soil or Oya stone. If you use the ones processed into a plate shape, it will be easier to attach them together.

As shown in FIGS. 2 and 3 (a) and (b), the in-wall space 3 is provided with one outer wall material so that ventilation is not obstructed by the pillar 11 portion and the cross beam portion. The ventilation member 10 is interposed between the inner surfaces of the members so that a ventilation path is secured in the formed gap.

[0016]

[Damper control method]

 The control method of the dampers 7a, 7b, 7c is as shown in FIG. 1, and in the summertime, in order to prevent the indoor temperature from rising, the high heat which rises and collects in the space 5 above the ceiling is removed. The damper 7b on the wife's side and the damper 7c on the back of the eaves to the ceiling space 5 are opened and discharged outside the room. At the same time, the damper 7a under the floor is opened to guide the low-temperature air entering the underfloor space 4 from the space 3 in the wall to the space 5 in the ceiling so that the room can be cooled.

In winter, as shown in FIG. 1, in order to prevent the room temperature from dropping, high hot air that rises in the space 3 on the south side on the south side (to the left in FIG. 1) and collects in the space 5 above the ceiling is removed. By closing the dampers 7b and 7c into the space above the ceiling, the dampers 7a and 7c in the underfloor space 4 are also closed so that low-temperature outside air does not enter. Then, the warm air in the space above the ceiling 5 descends in the space 3 in the north wall (to the right in FIG. 1), and the space 3 in the south wall, the space 5 above the ceiling, the space 3 in the north wall, and the space under the floor 4 in this order. A circulating flow occurs, which can maintain the indoor temperature efficiently.

[0018]

[Action and effect of the invention]

 The present invention is as described above. In summer, the heat energy heated by the sun is blocked by the space 3 inside the wall before being transmitted to the room, and the hot air there is guided to the space 5 above the ceiling, and the damper 7b, It is possible to prevent the room temperature from rising by discharging the air outside from the room 7c. At the same time, the low-temperature air sucked into the under-floor space 4 from the under-floor damper 7a is guided to the in-wall space 3 and the under-ceiling space 5, and the cool air prevents the indoor temperature from rising.

In winter, in order to prevent the room temperature from dropping, the air heated by the solar heat in the space 3 on the south side is collected in the space 5 above the ceiling by closing the dampers 7 b and 7 c, and The damper 7a is closed to prevent cold outside air from entering, so that the warmed air can be used effectively.

Then, the air from the outside sucked into the underfloor space 4 comes into contact with the adsorbing plate 8 in each of the spaces 3, 4, and 5, and causes nitrogen oxide or the like generated by combustion of a diesel engine or the like of an automobile. The harmful discharged fine particles are absorbed and purified by the adsorbing plate 8 and reach the space 5 above the ceiling. Then, the fresh purified air is taken into the room by the blower 9 from the space 5 above the ceiling.

As described above, in the present invention, in the summertime, the air containing harmful gas in the room is not purified and circulated for recycling as in the invention of JP-A-2001-140368, but is completely contaminated with formaldehyde. Since it is designed to take in fresh air and replace the room with fresh air, the deterioration of formaldehyde purification function due to the accumulation of formaldehyde in the adsorbent caused by long-term use as in the invention In addition, the possibility that the room is exposed to harmful substances, such as indoor reduction, can be eliminated. In winter, if all the dampers 7a, 7b, 7c are closed, the entire room can be warmed by circulating the air heated by the solar heat in the space 3 on the south wall to the spaces 3, 4, and 5. There is an advantage that can be.
