The exhaust duct 42 of the hood main body 41 and the duct 12 are communicated with each other through a connection duct 43.

Since the exhaust port 42 of the hood body 41 is displaced from the center of the wooden frame 3, the connection duct 43 is inclined with respect to the vertical posture.
That is, in the case of a blower using a multiblade fan, the suction port is concentric with the rotation center of the fan, and the exhaust port is shifted from the rotation center of the fan. When attached to the section, the exhaust port 42 is displaced from the center of the hood body 41, and the position of the center of the wooden frame 3 is shifted as described above.

As described above, by attaching the closing plate 11 to the wooden frame 3, the duct 12 can be easily disposed in the wooden frame 3, and the gap between the duct 12 and the inner peripheral surface 3 a of the wooden frame 3 is closed. 11 can be occluded.
Accordingly, the wooden frame 3 attached to the mounting hole 2 of the outer wall 1 and the exhaust duct of the newly installed ventilator 40 can be easily arranged outside the room using the mounting hole 2, Since the opening of the wooden frame 3 is closed, the outer wall 1 is not required to be repaired, and the work of replacing the existing ventilator with a new ventilator is simple, and the labor and cost can be reduced.

Next, the detail of each member is demonstrated based on FIG. 5, FIG.
The wooden frame 3 is formed as a rectangular frame body by an upper horizontal plate 3b, a lower horizontal plate 3c, and left and right vertical plates 3d.
The closing plate 11 of the replacement tool 8 has a rectangular plate shape larger than the wooden frame 3 having an upper end surface 11a, a lower end surface 11b, a left vertical end surface 11c, and a right vertical end surface 11d, and has a duct through hole 13. In addition, a plurality of small holes 14 are formed on the periphery of the duct through-hole 13.
The closing plate 11 is made of aluminum.
The duct through-hole 13, is formed so that one of left and right direction and upper and lower contrast deviated toward the position of the center 11e of the closing plate 11 is the center.
In FIG. 5, the center of the duct through-hole 13 is formed so as to be shifted to the left vertical end surface 11 c and the lower end surface 11 b from the center 11 e of the closing plate 11.

The duct 12 includes a one-side tube 16 having a flange 15 and an other-side tube 17 having a smaller diameter than the duct through-hole 13, and the other-side tube 17 is fitted and connected to the one-side tube 16. The duct 12 is provided.
Then, the other side cylinder 17 is inserted into the duct through hole 13 of the closing plate 11 and the flange 15 is closed and pressed against the surface of the closing plate 11 (the surface facing the indoor side) via an airtight material 18 (ring-shaped seal plate). It is fixed. For example, the bolt 19a is inserted through the hole 15a of the flange 15 and the small hole 14 of the closing plate 11 and screwed into the nut 19b to connect the duct 12 to the closing plate 11. The center of the duct 12 is more than the center 11e of the closing plate 11. It is fixedly attached so as to be shifted to the left and right and up and down.
The one side cylinder 16 protrudes more indoors than the surface of the closing plate 11, the other side cylinder 17 protrudes outward from the rear surface of the closing plate 11, and the outer peripheral surface of the other side tube 17 (duct 12). There is a gap between the closing plate 11 and the duct through hole 13.

Since it is as mentioned above, in order to attach the replacement tool 8 to the wooden frame 3, the left and right sides of the closing plate 11 (near the right vertical end surface 11 d in FIG. 5) and the other side of the top and bottom (near the upper end surface 11 a in FIG. 5) That is, the direction opposite to the direction in which the duct 12 is displaced is cut in accordance with the size of the wooden frame 3 (left-right dimension, vertical dimension) as shown by a one-dot chain line in FIG. Same size as
Then, the closing plate 11 is fixedly attached to the wooden frame 3 with a fixing tool 10a such as a screw.
Since it is like this, it can attach to the wooden frame 3 from which a magnitude | size differs, and the opening part of the wooden frame 3 can be obstruct | occluded, and a cutting operation | work is easy.

The non-combustible layer 20 includes an upper horizontal plate 21a, a lower horizontal plate 21b, and left and right vertical plates 21c made of a non-combustible material having a heat insulating property of 9.5 mm or more, and the upper horizontal plate of the wooden frame 3 3 b, the lower horizontal plate 3 c, and the left and right vertical plates 3 d are attached to the inner surfaces of the plates by fixing them with fixing tools 22 such as screws.
The bird net 30 is attached to the left and right vertical plates 21c (left and right vertical inner surfaces) of the incombustible layer 20 with fixing tools 32 by bending the left and right vertical edges into the mounting piece 31. It is attached.

  As described above, since the closing plate 11 is attached in contact with the incombustible material 6, heat such as oil smoke flowing through the duct 12 is not easily transmitted from the closing plate 11 to the wooden frame 3, and the wooden frame 3 does not burn.

Since there is a gap between the duct through hole 13 and the duct 12 of the closing plate 11 as described above, the insulating layer is provided between the flange 15 of the duct 12 and the closing plate 11 to close the duct 12. Since it is difficult for heat to be transmitted to the plate 11, the wooden frame 3 is not burned by heat of oil smoke or the like flowing through the duct 12 even if the closing plate 11 is attached in contact with the wooden frame 3.
For example, the above-described airtight material 18 is made of a material having heat insulation properties.

  In addition, when the heat insulating layer is provided as described above, the duct 13 and the closing plate 11 are in metal contact by connecting the flange 15 to the closing plate 11 with a plurality of fixing tools (bolts 19a and nuts 19b) such as screws. Since the part to do becomes a point contact, the transmission of heat from the duct 13 to the closing plate 11 is further reduced.

  Examples of the non-combustible material having heat insulation include calcium silicate board, gypsum board, rock wool, glass wall, and a material called MOISS in which vermiculite, a clay mineral, is added to a calcium silicate base material. desirable.
