得る。In this way, in this embodiment, since the fitting recesses 20 to 22 are provided in which the engagement piece 18 is detachably fitted, any of the exhaust ports 3 to 5 of the hood body 1 can be selectively connected to the duct 8. When connecting the blower 10 to a heavy blower 10, the blower 10 can be temporarily held by fitting the engagement piece 18 into the fitting recess when reattaching the blower 10 after removing it and changing its direction. Unlike other devices that have to support the entire weight of the hood, the blower 10 can be easily installed, and the work efficiency can be improved by attaching the hood body 1 to the chamber wall 6.

し得る。Moreover, since the fitting recesses 20 to 22 are formed by bulging out the opening edges of the exhaust ports 3 to 5, this is different from a structure in which separately formed support pieces are welded to the peripheral edge of each exhaust port. Therefore, the number of parts can be reduced, contributing to cost reduction.

る。In addition, in this embodiment, the inner width of the fitting recesses 20 to 22 is formed approximately equal to the width of the engaging piece 18, so that the fan casing can be closed by fitting the engaging piece 18 into the fitting recess. 9 on the exhaust port 12 side, the through holes 23 and 24 of the joint plate 16 are connected to the female threaded portions 25 and 26 of the exhaust port.
Since the blower automatically matches the position of the blower, the work is extremely easy, unlike when positioning the blower while supporting it by hand.

加えて、係合片１８を嵌合凹部に嵌合したとき、ゴム製
のシール部材１９の弾性力により係合片１８が嵌合凹部

を防止できる。In addition, when the engaging piece 18 is fitted into the fitting recess, the elastic force of the rubber sealing member 19 presses the engaging piece 18 against the inner surface of the vertical wall of the fitting recess, so that there is no leakage from the fitting recess. Air leakage can be prevented.

尚、上記実施例ではレンジ用換気扇に適用したが、ダク
ト用換気扇などの換気装置一般に広く適用できる。Although the above embodiment is applied to a range ventilation fan, the present invention can be widely applied to ventilation devices in general such as a duct ventilation fan.

る。As explained above, even if the orientation of the duct differs depending on the house, the present invention eliminates the need for a heavy blower when selectively connecting the exhaust port of the outer box to the duct depending on the orientation. It can be installed while being held in the mating recess, improving work efficiency.Moreover, since the mating recess is a bark formed on the outer box by bulging molding, an increase in the number of parts can be prevented and costs can be reduced. It is possible to provide a ventilation device that can contribute to reducing the amount of waste.
