<P>PROBLEM TO BE SOLVED: To provide an air supply type ventilation device of good maintenance performance and good air distribution performance while reducing filter pressure loss. <P>SOLUTION: This air supply type ventilation device comprises a main body frame 8 provided with a flange portion 6 disposed on an indoor-side outer periphery of a cylindrical portion 5 mounted on a wind tunnel panel 4 buried in a wall portion 3 in a state of communicating the outside of room 1 and the inside of room 2, a motor 9 and a fan 10 connected to the cylindrical portion 5 of the main body frame 8 through a motor supporting portion, a square frame-shaped filter receiving portion 11 projecting to an indoor 2 side of the main body frame 8, a plate-shaped filter 12 received in the filter receiving portion 11, and a front panel 15. A position 16 of a depth part of the filter receiving portion 11 is determined at a cylindrical portion 5 side with respect to a face of the flange portion 6, and the plate filter 12 is disposed near a wall portion 3 side, thus the maintenance performance can be improved, and the good air distribution performance with small filter pressure loss can be achieved. <P>COPYRIGHT: (C)2008,JPO&INPIT |
