According to the airtight ventilation fan flange structure of this embodiment, it is possible to reduce the size of the suction grille (7), which has a large peripheral portion because of the necessity of covering the conventional ventilation fan flange (11). If the opening area of the ventilation fan is the same, it is clear from the economical viewpoint that the suction grille should be smaller, and it is also preferable in terms of design. Further, according to the present embodiment, continuity with the airtight surface (12) of the upper surface of the ceiling base material (4) is easily ensured. Further, by providing the ventilation fan frame extension (8), the cut surface of the ceiling base material can be hidden, and the ceiling base material can be hit to enhance workability.

枠寸法と強度が確保できれば本実施例に限らない。The airtight ventilation fan flange structure according to the present embodiment according to the present embodiment is of a type in which a flange is mounted on a ceiling edge. Therefore, after forming a mounting frame on the ceiling edge, a ventilation fan frame is fitted over the mounting frame and fixed with mounting screws. Since the length of the ventilation fan extension has the width of the ceiling base material and the ceiling base material, the cut surface of the ceiling base material is hidden, the ceiling base material is hit, and the workability is improved. There is no difference from the first embodiment. Furthermore, since there is tightening from the top and support of the ceiling edge at the bottom, there is less danger of falling due to loosening of the mounting screws. The effect of airtightness is the same as in the first embodiment. In this embodiment, the ceiling edge and the mounting frame are each two sides, but depending on the structure, four sides may be the mounting frame, or three sides may be the mounting frame,
The present invention is not limited to this embodiment as long as the frame dimensions and strength can be secured.

The effect is great in terms of economy and design. Further, according to the present embodiment, air-tightness is also ensured, which is a disadvantage of the conventional flange structure, which is caused by discontinuity of the air-tight surface and impairs air-tightness. Further, the extension of the ventilation fan frame hides the cut surface of the ceiling base material, and can also be expected to have an effect of hitting the ceiling base material and improving workability.
