AIR PERMEABLE DOOR
PROBLEM TO BE SOLVED: To provide an air permeable door that has a simple inner structure and can exert high sound insulation performance.SOLUTION: Partitioning an inner space of an air permeable door 1 by an air permeable region partition body 16, a left side guide partition body 17 and a right side guide partition body 18 forces air to pass through a rear side communication space 19a, an upper space 19b, a left side space 19c or a right side space 19d, a lower space 19e, and a front side communication space 19f before the air reaches a front side air permeable region 15a installed in a front door from a rear side air permeable region 15b installed in a rear door 11b. Thus a sound transmission distance elongates as the sound passes through the same route as the air, which increases distance attenuation of propagation sound transmitted through the door inner space, so that high sound insulation performance can be realized.SELECTED DRAWING: Figure 2
【課題】簡易な内部構造で高い遮音性能を発揮できる通気性扉を提供する。【解決手段】通気性扉１の内空部を通気領域仕切体１６と左側誘導仕切体１７と右側誘導仕切体１８で仕切ることにより、背面扉１１ｂに設けた背面側通気領域１５ｂから前面扉に設けた前面側通気領域１５ａへ空気が至るまでに、背面側連通空部１９ａと上方空部１９ｂと左側空部１９ｃ又は右側空部１９ｄと下方空部１９ｅと前面側連通空部１９ｆを通らなければならなくなり、音の伝搬距離も同じ経路となって長くなるため、扉内空部を伝わる伝搬音の距離減衰が大きくなり、高い遮音性能を実現できる。【選択図】図２
