It has one opening 1a which is located and opens to the outside. The left and right upper frames 20 and 20 (hereinafter referred to as single numbers; hereinafter omitted) of the ventilation fan mounting outer frame 2 are provided with slide rails 3, and the left and right lower frames 21 are provided with guide rails 30. The slide rail 3 is provided with a movable body 6 that supports a shutter frame 4 of a shutter via a bearing 7 so as to be movable. Next, the support relationship between the shutter frame 4 and the slide rail 3 and / or the guide rail 30 will be described. A stopper 8 is pivotally supported on the moving body 6, and the stopper 8 is attached to the upper frame 40 of the shutter frame 4. Pivot inside. Further, a stopper 80 is pivotally supported on the guide rail 30, and this stopper 80 is pivotally attached to the lower frame 41 of the shutter frame 4. Accordingly, when the movable body 6 is moved along the slide rail 3 to the inner side A1 of the house A, the shutter frame 4 is moved to the inner side A1, and the distal end side of the movable body 6 is positioned on the distal end side of the slide rail 3. At the same time, the lower frame 41 of the shutter frame 4 is positioned on the front end side of the guide rail 30 during this movement. That is, the slide rail 3 has a length approximately twice that of the guide rail 30 in order to reliably follow the moving body 6. As a result, the shutter frame 4 is moved in a substantially horizontal state, and the stability and safety of work and / or movement in the house A are ensured. Alternatively, a channel-shaped guide rail 30 may be used, and the lower frame 41 of the shutter frame 4 may be inserted into the recess of the guide rail 30. In the figure, reference numeral 10 denotes a shutter plate mounting plate provided on the shutter frame 4, and a plurality of shutter plates 11 are pivotally supported on the shutter plate mounting plate 10 so as to be freely opened and closed. The shutter plate 11 is opened by the rotation of the fan 12 and is closed by the rotation stop. Reference numeral 13 denotes a motor for driving the fan 12. Although not shown, the shutter plate 11 may be a static pressure type. The shutter plate 11 can be simultaneously opened and closed by a connecting plate (not shown).

  In the configuration as described above, in FIG. 1 showing an example in which one opening 1a functions for intake and the other opening 1b functions for exhaust by changing the direction of the ventilation fan, the moving body 6 is a slide rail 3. Of the shutter frame 4 (with the stoppers 8 and 80 or the fan 12 and the shutter frame 4 in the state where the stopper 8 is located at the approximate center). When the upper frame 40 is moved and / or stopped together), the lower frame 41 and / or the stopper 80 of the shutter frame 4 are positioned on the front end side of the guide rail 30. In this state, the shutter plate 11 is on the inner side A1 of the house A, and the fan 12 and the motor 13 are located on the wall side A2 of the house A. In this state, one opening 1a is on the intake side and the other opening 1b is on the exhaust side. In this state, by rotating the fan 12, the shutter plate 11 is opened and the outside air is introduced into the house A. This flow of air (wind) is indicated by an arrow “I”. From this state, the shutter frame 4 is rotated with the fasteners 8 and 80 as fulcrums, and the fan 12 and the motor 13 are simultaneously rotated. At the time of this rotation, the front end side of the shutter frame 4 can smoothly rotate without stopping at least on the cover 1 (in the example of stopping at other than the cover 1, it is treated), and a ventilation fan (shutter frame 4, stopper) 8, 80 or the fan 12 and the motor 13 etc.) are reversed and are in the opposite direction. Therefore, the movable body 6 (or a shutter or the like) is pushed, and substantially the entire movable body 6 is inserted into the slide rail 3, and the stopper 8 provided on the movable body 6 is attached to the base end side of the slide rail 3 (toward the drawing).

The stopper 8 is located on the tip side of the hole 300, and the shutter frame 4 is in the same position. Therefore, the shutter plate 11 is located on the inner side A1 of the house A, and the fan 12 and the motor 13 are located on the wall side A2 of the house A. In this state, one opening 1a is on the intake side and the other opening 1b is on the exhaust side. Accordingly, by rotating the fan 12, the shutter plate 11 is opened and the outside air is introduced into the house A. This air (wind) flow is indicated by an arrow “c”. From this state, the shutter frame 4 is rotated with the stopper 8 as a fulcrum, and the fan 12 and the motor 13 are simultaneously rotated. During this rotation, the front end of the shutter frame 4 can smoothly rotate without stopping against the cover 1, and the ventilation fan is inverted and reverses the above-described direction. Therefore, the ventilation fan is pushed, the stopper 8 of the shutter frame 4 is moved along the long hole 300, and the stopper 8 is brought to the base end side. Then, as shown in FIG. 9, the shutter frame 4 is the other opening 1b and is located on the same line as the ventilation fan mounting outer frame 2. In this state, the fan 12 and the motor 13 are located on the inner side A1 of the house A, and the shutter plate 11 is located on the outer side of the wall side A2 of the house A. In this state, the other opening 1b is on the intake side, and one opening 1a is on the exhaust side. Therefore, by rotating the fan 12, the shutter plate 11 is opened, and the air in the house A is exhausted outside the house A. This air flow is indicated by an arrow “d”.

The shutter frame 4 is pivotally supported by stoppers 8a and 80a on the distal end sides of the second upper and lower brackets 52 and 53. In this configuration, in the state shown in FIG. 12 in which the second upper and lower brackets 52 and 53 are superimposed on the first upper and lower brackets 50 and 51, the fasteners 8a and 80a provided on the second upper and lower brackets 52 and 53 are provided. And / or the shutter frame 4 is exactly on the axis of the ventilation fan mounting outer frame 2. Therefore, the shutter plate 11 is located on the inner side A1 of the house A, and the fan 12 and the motor 13 are located on the wall side A2 of the house A. In this state, one opening 1a is on the intake side and the other opening 1b is on the exhaust side. Accordingly, by rotating the fan 12, the shutter plate 11 is opened and the outside air is introduced into the house A. This air flow is indicated by an arrow “e”. Then, by rotating the shutter frame 4 with the shafts 54 and 55 supporting the shutter frame 4 as fulcrums, the second upper and lower side brackets 52 and 53 are simultaneously rotated. By this rotation, as shown in FIG. 13, the second upper and lower brackets 52 and 53 protrude from the distal end side of the first upper and lower brackets 50 and 51. As a result, the shutter frame 4 is supported via the stoppers 8a and 80a provided on the leading ends of the protruding second upper and lower brackets 52 and 53. In this state, the fan 12 and the motor 13 are located on the inner side A1 of the house A, and the shutter plate 11 is located on the outer side of the wall side A2 of the house A. In this state, the other opening 1b is on the intake side, and one opening 1a is on the exhaust side. Therefore, by rotating the fan 12, the shutter plate 11 is opened, and the air in the house A is exhausted outside the house A. This air flow is indicated by an arrow “to”.
Also in the third embodiment, other configurations and / or features are the same as those in the first and second embodiments described above.
