However, the protruding dimension of the ventilation hood from the wall surface is large and the width dimension of the ventilation hood is also large, which detracts from the exterior appearance (aesthetic appearance) of the building. Therefore, the exhaust amount characteristic 24 and the air supply amount characteristic 25 are improved as shown in FIG. 6 while the exterior dimension is greatly improved by reducing the protruding size and size from the wall surface of the hood.

出される。Further, as shown in FIG. 7, when external air from the side surface is applied to the ventilation hood 12, static pressure is generated in the duct 11 due to the external air. As shown in FIG. 9, the conventional ventilation hood of FIG. 8 has a static pressure characteristic D, whereas the ventilation hood 10 of the present invention of FIG. 7 has a static pressure characteristic 26, which is small. This small static pressure characteristic, which is the resistance to exhaust gas, means that the amount of exhaust gas does not decrease even when outside wind acts, and more exhaust gas can be secured than conventional ventilation hoods. Since it is not necessary to increase the rotation speed of the ventilation fan, noise in the room is reduced. In addition, the slant of the side surface is set in the vertical direction and the inclination angle of the slant surface is set to about 20
By setting the angle to 15 degrees, the resistance of the opening 15 is small, and the side wind easily passes through the hood 12. In addition, the venturi effect due to the side wind occurs due to the horizontally long gully provided in the opening on the lower surface of the hood, and the air in the ventilation hood is sucked out.

ムーズにして正面から受ける風圧力を緩和できる。Since this ventilation hood is constructed as described above, even if rainwater of 200 mm / hr acts by outside wind (20 m / s) from any angle, very little rainwater enters the duct 11. This is because rainwater flows down along the vertical louver surface, so it rarely enters the duct directly. Also, even if rainwater enters the ventilation hood, it can be drained smoothly from the drain hole on the lower surface, so that a large amount of water does not accumulate in the hood. Further, since the ventilation hood has an inclined surface extending from the center to the tip, rainwater flows smoothly, and the flow of outside wind from the front can be smoothed to reduce the wind pressure received from the front.

Further, since the collision force of raindrops is dispersed by the slope and the collision noise is reduced, noise can be reduced. Further, since the side surface between the front surface portion 12b of the ventilation hood and the side surface louver 16 is configured to be closed with 12c, the front surface 1
It is possible to prevent the wind hitting 2b from blowing out sideways along the front of the hood, and it is possible to exhaust air diagonally forward along the angle of 20 degrees on the glazed surface, and the air supply / exhaust hoods are arranged side by side on the same wall surface. When installed in, the number of short circuits in which exhaust gas is sucked into the adjacent air supply hood can be reduced.

By setting it to 0 mm or more, it is possible to avoid the turbulent flow part of the external wind near the wall surface, and it is possible to further enhance the exhaust performance and the effect of preventing rainwater from entering the duct.
