  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

(Embodiment 1)
As shown in FIG. 1, a range hood 2 as a first exhaust ventilation fan, which is a first ventilation device, is installed in a kitchen 1, and a second ventilation device is provided on an outer wall 3 at a position away from the range hood 2. The air supply shutter 4 is installed. The range hood 2 is provided with an infrared transmission unit 6 that transmits an operation or stop signal 5, and the air supply shutter 4 is provided with a reception unit 7 that receives the signal 5 from the transmission unit 6 of the range hood 2. When the hood 2 is operated, an operation signal 5 is transmitted from the transmission unit 6, the signal 5 is received by the reception unit 7 of the supply shutter 4, the supply shutter 4 is opened, and the operation of the range hood 2 is stopped. Then, a stop signal 5 is transmitted and the air supply shutter 4 is closed.

  The stop operation of the operation of the range hood 2 and the transmission of the stop signal 5 are not simultaneously, but the transmission of the stop signal 5 is delayed for a predetermined time with respect to the stop operation.

  With the above configuration, when the range hood 2 is operated and the air in the kitchen 1 is exhausted, the air supply shutter 4 is opened in conjunction with this, and the outdoor air is supplied into the kitchen 1, and the differential pressure between the room and the outdoor is reduced. Thus, efficient exhaust can be performed, that is, ventilation efficiency is improved.

  When the operation of stopping the range hood 2 is stopped, the stop signal 5 is transmitted with a predetermined time delay, and the air supply shutter 4 is closed. Therefore, after the stop operation, air supply according to the exhaust of the range hood 2 that has been rotating with inertial force for a while can be obtained, and the differential pressure that has been reduced can be maintained.

  And the improvement of such ventilation efficiency can be achieved at a low installation cost by configuring without relatively wiring with a relatively inexpensive member that transmits and receives the infrared signal 5.

  On the other hand, the range hood 2 has a specification that allows the rotational speed to be switched between high speed, medium speed, and low speed. When the range hood 2 is operated at a high speed, the ventilation fan 8 opens the shutter 9 in conjunction with the operation. When the high speed operation is performed and the range hood 2 is operated at a medium speed, the shutter 9 is opened and the supply ventilation fan 8 is operated at a low speed. When the range hood 2 is operated at a low speed, the supply ventilation fan 8 opens the shutter 9. When the range hood 2 is stopped, the supply ventilation fan 8 closes the shutter 9.

  With the above-described configuration, the difference in pressure between the kitchen 1 and the outdoor increases during the high-speed operation of the range hood 2 by transmitting and receiving the signal 5 from the transmitter 6 of the range hood 2 to the receiver 7 of the ventilation fan 8 for supplying air. When the range hood 2 is switched to medium speed operation, the exhaust fan 8 is operated at low speed to obtain a small amount of air supply when the range hood 2 is switched to medium speed operation. When the range hood 2 is switched to low speed operation, the air supply ventilation fan 8 is stopped and the shutter 9 remains open in order to obtain a smaller amount of air corresponding to the range hood 2. Even when operated at a low speed, the differential pressure between the kitchen 1 and the outdoor space is properly maintained. When the range hood 2 is stopped, the shutter 9 is closed after a predetermined delay time.

(Embodiment 3)
The ventilator according to the third embodiment of the present invention allows the rotation speed of the range hood 2 to be switched between high speed, medium speed, and low speed with respect to the ventilator according to the second embodiment, and the supply ventilation fan 8 also rotates. The speed can be switched between high speed, medium speed, and low speed, and the rotational speed of the ventilation fan 8 is switched according to the switching of the rotational speed of the range hood 2, that is, according to the magnitude of the exhaust air volume. It is characterized by interlocking to increase or decrease the air volume.

  With the above configuration, the range hood 2 and the air supply ventilation fan 8 are interlocked so as to maintain an appropriate indoor / outdoor differential pressure at any rotational speed, and stable and efficient exhaust can be performed.

Is installed in the living room 11 communicating with the kitchen 1. The second exhaust ventilation fan 10 includes a shutter 12 for preventing outside wind from entering when stopped.

  Then, when the range hood 2 is operated while the second exhaust ventilation fan 10 is in operation, the second exhaust ventilation fan 10 stops with the shutter 12 open, and the differential pressure inside and outside the room due to the stop of the second exhaust ventilation fan 10. The range hood 2 efficiently exhausts by preventing the rise and the pressure difference due to the air supply obtained by opening the shutter 12 so that the pressure difference between the living room 11 and the outside of the kitchen 1 does not increase. It can be so. Then, when the range hood 2 is stopped, the exhaust in the living room 11 is resumed.

  In the fourth embodiment, the range hood 2 in which the first exhaust ventilation fan is installed in the kitchen 1 is used. However, the chamber in which the first exhaust ventilation fan is installed is not limited to the kitchen 1. And the second exhaust ventilator are installed in a room communicating with each other, the same effect is obtained.
