The outdoor exhaust port 5 is connected to a duct penetrating the wall portion 9 and communicates with the outdoors.

また、室内側排気口４の中心位置（ａ）が湾曲基点６を結ぶ線１０より壁部９側に位置するように室内側排気口４を本体３の側面に設け、排気用ファン２の中心線（ｂ）を本体３の前面に形成された湾曲部７における膨張量が最大の部位１１を通る壁部９に対して垂直方向の線、すなわち、本体３の中心線（ｃ）より上方側となる一方側にずらし、他方側となる下面に室内側排気口４を設け構成する。   Further, the indoor exhaust port 4 is provided on the side surface of the main body 3 so that the center position (a) of the indoor exhaust port 4 is located on the wall 9 side from the line 10 connecting the curved base point 6, and the center of the exhaust fan 2 is provided. The line (b) is a line perpendicular to the wall portion 9 passing through the portion 11 having the maximum expansion amount in the curved portion 7 formed on the front surface of the main body 3, that is, above the center line (c) of the main body 3. The indoor side exhaust port 4 is provided on the lower surface on the other side.

また、排気用ファン２の回転軸線である中心線（ｂ）は壁部９に対して垂直方向に設けられ、排気用ファンの吸込口２ａは本体３の前面裏側と向かい合っている。   A center line (b), which is the rotational axis of the exhaust fan 2, is provided in a direction perpendicular to the wall portion 9, and the suction port 2 a of the exhaust fan faces the front back side of the main body 3.

The provided air supply ventilation means 16 is integrally provided to be a simultaneous supply / discharge type, and the suction center height (H) of the exhaust fan 2A and the supply fan 15 is provided in the wall portion 9A. The exhaust passage 18 and the air supply passage 19 communicate with each other, are formed at the same height as the center of the outdoor exhaust port 5A and the outdoor air supply port 13, and an outdoor hood is provided on the outdoor side of the two-layer pipe duct 17 20 is provided and configured.

上記構成において、排気用換気手段１４と給気用換気手段１６が同時に運転されると、排気用ファン２Ａが駆動し、本体３Ａの下面に設けた室内側排気口４より排気用ファン２Ａに吸い込まれた排気流は、室外側排気口５Ａより２層管ダクト１７の排気路１８を通り室外に排気され、給気用ファン１５が駆動し２層管ダクト１７の給気路１９より、室外の空気を吸気し、室外側給気口１３より給気用ファン１５を経て本体３の上面および前面に設けた室内側給気口２１より室内に給気されることとなる。   In the above configuration, when the exhaust ventilation means 14 and the supply ventilation means 16 are operated simultaneously, the exhaust fan 2A is driven and sucked into the exhaust fan 2A from the indoor side exhaust port 4 provided on the lower surface of the main body 3A. The exhaust flow is exhausted from the outdoor exhaust port 5A through the exhaust path 18 of the two-layer pipe duct 17 to the outside, and the air supply fan 15 is driven to drive the outdoor layer from the air supply path 19 of the two-layer pipe duct 17. Air is sucked in, and air is supplied into the room from the indoor air supply port 21 provided on the upper surface and the front surface of the main body 3 through the air supply fan 15 from the outdoor air supply port 13.

そして、排気用換気手段１４と給気用換気手段１６を一体的に設けたことにより、一本の２層管ダクト１７で給気と排気を同時に行うことができる。   Further, by providing the exhaust ventilation means 14 and the air supply ventilation means 16 integrally, it is possible to supply and exhaust air simultaneously with a single two-layer pipe duct 17.

また、排気用ファン２Ａおよび給気用ファン１５の吸い込み中心高さ（Ｈ）を室外側排気口５Ａと室外側給気口１３および２層管ダクト１７の高さと合致するように同一高さに形成していることにより、排気用ファン２Ａから室外側排気口５Ａを経て、２層管ダクト１７の排気路１８に流れる排気流はスムーズに流れ、その結果排気用ファン２Ａの吸気効率が高められるとともに、２層管ダクト１７の給気路１９より室外側給気口１３を経て給気用ファン１５に吸い込まれる給気流は、スムーズに流れ給気用ファン１５の吸気効率が高められることとなる。   Further, the suction center height (H) of the exhaust fan 2A and the air supply fan 15 is set to the same height so as to match the heights of the outdoor exhaust port 5A, the outdoor air supply port 13 and the two-layer pipe duct 17. By forming, the exhaust flow flowing from the exhaust fan 2A through the outdoor exhaust port 5A to the exhaust path 18 of the two-layer pipe duct 17 flows smoothly, and as a result, the intake efficiency of the exhaust fan 2A is increased. At the same time, the air supply air sucked into the air supply fan 15 from the air supply path 19 of the two-layer pipe duct 17 through the outdoor air supply port 13 flows smoothly and the intake efficiency of the air supply fan 15 is enhanced. .

本発明の換気装置は、同時に給気と排気を２層管ダクトを介して行う熱交換形換気装置などにも適用できる。   The ventilator of the present invention can also be applied to a heat exchange type ventilator that simultaneously supplies and exhausts air through a two-layer pipe duct.
