UNDERFLOOR VENTILATION CONTROL DEVICE
To provide an underfloor ventilation control device capable of supplying sufficient outside air to an underfloor space by easily taking into the underfloor space a wind in a direction along an outer surface of a foundation in which the underfloor ventilation control device is disposed.SOLUTION: The present invention relates to an underfloor ventilation control device 100 comprising: a passage cylinder 10 which can be inserted into a through hole 220 of a foundation 200; an outside air take-in part 20 and a stationary part 30 formed in respective ends of the passage cylinder 10; a first spring 40 and a second spring 50 which are disposed between the outside air take-in part 20 and the stationary part 30 and at least one of which is formed from a spring consisting of a heat sensitive alloy; and a valve body 60 which is movable close to and separate from a valve seat 19 by a difference of energizing forces of the first spring 40 and the second spring 50 caused by a change of an outside air temperature. The outside air take-in part 20 includes a standing wall 14 erected in a flange 12 of the passage cylinder 10, and a closer 16 mounted in a tip end of the standing wall 14. An outside air take-in port 22 through which outside air can be taken in a direction orthogonal to an axial direction of the passage cylinder 10 is disposed in a part of the standing wall 14.SELECTED DRAWING: Figure 6
【課題】床下通気制御装置が配設される基礎の外表面に沿った方向からの風を床下空間に取り込み易くして、床下空間への十分な外部空気の供給が可能な床下通気制御装置を提供すること。【解決手段】基礎２００の貫通孔２２０に挿通可能な流路筒１０、流路筒１０の両端部にそれぞれ形成された外部空気取込部２０と固定部３０、外部空気取込部２０と固定部３０との間に配設され、少なくとも一方が熱感知式合金からなるばねにより形成された第１ばね４０および第２ばね５０、外気温の変化に伴って生じる第１ばね４０と第２ばね５０の付勢力の差によって弁座１９に接離動可能な弁体６０を具備し、外部空気取込部２０は、流路筒１０のフランジ部１２に立設された起立壁１４、起立壁１４の先端に取り付けられた閉塞体１６を有し、起立壁１４の一部に流路筒１０の軸線方向直交方向から外部空気を取り込み可能な外部空気取込口２２を配設した床下通気制御装置１００である。【選択図】図６
