In the hourly exhausting type of ventilators equipped with a communicating relationship solutions comb Yatta plate with cover air inlet and exhaust communication port and the cover outlet
The air supply and exhaust communication ports of the body casing
The cover air supply port and the cover exhaust port are located side by side and close to each other, and the shutter plate has vertical grooves.
The cover is provided with a diagonal slide groove.
There is a column that slidably passes through the groove and the groove of the shutter plate.
Provided example was damper shutter plate, grooves and slide the damper by lateral movement by the slide of the shutter <br/> ter plate
The support is moved by the displacement of the intersection with the groove, and the sliding position of the shutter plate that opens the air supply communication port and the exhaust communication port is in the position away from the shutter air supply port and the shutter exhaust port, and the air supply communication shea to solve the communication of the mouth and the exhaust communication port
When the shutter plate slides, close the shutter exhaust port.
A means that is configured to be at a stop position is adopted.

[0007]

According to the present invention, a shutter plate is provided by employing the above means.
To release the communication between the air supply port and the exhaust port.
Occasionally, the second shutter moves as the shutter plate slides.
The damper, which can be said to be a
Either the air intake port or the shutter exhaust port is closed
The air supply and exhaust ports of the main body casing can be
It becomes possible to provide the entrance very close.

Reference numeral 40 denotes a slide groove which is inclined below the shutter exhaust port and air supply port and is formed in the vertical direction.
Has the same length of stroke as the movement stroke. 4
Reference numeral 1 denotes a guide portion provided around the pipes 2 and 3 in the slide groove. Reference numeral 42 denotes a damper which is formed to be larger than the outer shape of each of the air supply communication port 30 and the exhaust communication port 31. Are connected. Reference numeral 44 denotes a mounting plate on which the supply pipe 3 and the exhaust pipe 2 are fitted at the same pitch as the discharge communication ports 30 and 31.

In the ventilation fan constructed as described above, the shutter plate 32 is provided in the cover 36 between the mounting plate 44 and the main body case 11 as shown in FIG. The support 42 is mounted by inserting the support 43 into the groove 35, and the support 43 is also inserted into the slide groove 40, so that the support 43 is incorporated into the back of the main body case 11. Then, the main body case 11 is mounted on the mounting plate 44 mounted on the wall, and the electric motor 14 is operated in the same manner as in the related art, so that the indoor air enters the main body casing 11 through the suction port 9 and is heated by the heat exchanger 19. It is exchanged and exhausted from the exhaust communication port 31 to the outside through the exhaust pipe 2. On the other hand, the outdoor air enters the main body case 11 from the air supply pipe 3 through the air supply communication port 30, exchanges heat with the heat exchanger 19, and is supplied into the room from the discharge port 10.
When the operation is stopped, the shutter plate 32 and the simultaneous support column 43 are moved upward while sliding in the groove 35 and the slide groove 40 as shown in FIG. Seals between the air supply communication port 30 and the air supply pipe 3. And shutter plate 3
When 2 is returned to its original position, the column 43 moves downward. Accordingly, when the interval between the exhaust pipe 2 and the supply pipe 3 is shorter than the diameter of each pipe 2, 3, the exhaust communication port 31 is connected to the damper 4.
Sealed at 2. Also, as shown in FIG.
The support column 43 is provided with the
