Subsequently, the intake fan motor 27 and the exhaust fan motor 37 are driven to rotate the intake fan 25 and the exhaust fan 35 so that air is introduced into the room from the outside and exhausted from the indoor air to the outside for ventilation. do. In addition, the warning light 14 (see FIG. 2) installed on the rear surface of the housing 10 sends a signal to a person in the room by a warning sound and a flashing light to recognize an abnormal temperature and a gas leak. When the room temperature drops below a predetermined temperature due to such ventilation, gas is no longer detected, or the air conditioner is no longer operated, the control unit controls the door motor 42 and the intake fan motor 27 by a signal from the sensor 15. And a signal is sent to the exhaust fan motor 37 to stop the intake fan 25 and the exhaust fan 35 to close the intake passage 22 and the exhaust passage 32.

When the user sets the ventilation device 100 to the manual mode by operating the remote control, it is possible to operate only by the remote control. The user can select three modes of intake, exhaust, intake and exhaust.

When the intake air is selected, the intake air passage 24 rotates to open the intake passage 22, and the intake fan 25 rotates to intake air from the outside. In this case, the exhaust door 34 is also opened by rotating the exhaust door 34 together with the intake door 24, but since the exhaust fan 35 does not rotate, exhaust is not performed.

When the exhaust gas is selected, the exhaust door 34 rotates as described above to open the exhaust passage 32, and the exhaust fan 35 rotates to exhaust the indoor air to the outside. As described above, the intake airway 24 is also rotated together with the exhaust door 34 to open the intake passage 22. However, since the intake fan 25 does not rotate, intake is not performed.

When the intake and exhaust are selected, the above-described intake and exhaust processes are simultaneously performed to provide ventilation.

Finally, when the ventilator 100 is set to the composite mode, not only can it be operated by the remote controller, but also the sensor 15 can detect the temperature abnormality, gas leakage, or wind pressure even if there is no operation by the remote controller. In the case of detection, the air is automatically driven and controlled by the control unit.

On the other hand, when the user cuts off the power of the ventilator 100 or suddenly cuts off the power of the ventilator 100 due to a power failure, the driving of the intake fan 25 and the exhaust fan 35 is controlled by the control of the controller. It stops and closes the intake passage 22 and the exhaust passage 32 to prevent foreign substances from entering the room.
