The members, arrangements, and the like described below do not limit the present invention, but can be variously modified within the scope of the present invention.
[0010]
The ventilation control device in this example has a ventilation controller 2 as ventilation driving means, and the ventilation controller 2 operates the ventilation fan 1 by a control signal from a CPU 5 used for the air conditioner 3. Things.
That is, the air conditioner 3 includes a humidity sensor 4 as a detecting means, a CPU 5 as a control signal generating means, and an interface circuit (abbreviated as "I / F" in FIG. 1) 6 for interfacing the CPU 5 with the humidity sensor 4. And a drive circuit 7.
[0011]
The humidity sensor 4 detects the humidity in the room, and the detection signal is input to the CPU 5 via the interface circuit 6.
The CPU 5 controls a lever and a fan (both not shown) of the air conditioner 3 via a drive circuit 7, and outputs necessary control signals to the ventilation controller 2 according to the detection result of the humidity sensor 4. It is something like that.
In this embodiment , the CPU 5 and the drive circuit 7 implement a periodic drive unit.
[0012]
FIG. 2 is a flowchart showing the procedure of the control operation of the present apparatus. Hereinafter, the operation of the present apparatus will be described with reference to FIG.
When the power is turned on to the apparatus, first, a louver and a fan (not shown) of the air conditioner 3 are started by a control signal from the CPU 5 via the drive circuit 7 at regular time intervals, and indoor air is taken in before the humidity measurement. (Step 100 in FIG. 2).
[0013]
Subsequently, the detection signal from the humidity sensor 4 is taken into the CPU 5 via the interface circuit 6 (step 102 in FIG. 2), and it is determined whether the humidity is equal to or higher than a predetermined value (step 104 in FIG. 2). .
If it is determined that the humidity is still less than the predetermined value, the driving of the lever and the fan is performed again after a predetermined time (step 104 in FIG. 2).
[0014]
On the other hand, when it is determined that the humidity is equal to or more than the predetermined value, a control signal is output from the CPU 5 to the ventilation fan controller, and the ventilation controller 2 starts the ventilation fan 1 according to the control signal, and the indoor ventilation is equal to or more than the predetermined value. Automatically at humidity of

Next, an embodiment of the present invention will be described with reference to FIGS.
Real施例This is obtained so as to drive the duct ventilator using the humidity detection result by the air conditioner provided in a plurality of room.
That is, as shown in FIG. 3, in the actual施例this, each to no room A to C air 3a~3c are provided.
The basic electrical configuration of each of the air conditioners 3a to 3c is the same as that shown in FIG.
[0016]
In each of the rooms A to C, ventilation controls 2a to 2c are provided, and output signals of the ventilation controllers 2a to 2c are input to the controller 8.
Each of the ventilation controllers 2a to 2c receives a control signal from each of the air conditioners 3a to 3c in the living room as described in FIG.
The controller 8 calculates the logical sum of the signals for driving the ventilation fans output from the ventilation controllers 2a to 2c and outputs the logical sum to the supply ventilation fan 9 and the exhaust fan 10 ( (See FIG. 4).
[0017]
Ventilation ports 11a to 11c are provided in each of the rooms A to C, and the ventilation ports 11a to 11c communicate with the air supply duct 12 and the exhaust duct 13. The other end of the air supply duct 12 communicates with the ventilation fan 9 for air supply, and the other end of the air duct 13 communicates with the fan 10 for exhaust air, so that air supply and exhaust are performed. ing.
[0018]
The air supply ventilation fan 9 and the exhaust fan 10 are driven when a drive signal is output from any of the ventilation controllers 2a to 2c via the controller 8.
[0019]
The operation in this configuration will be described. First, the louvers and fans (not shown) are periodically rotated in the air conditioners 3a to 3c of each living room, and then the humidity determination by the humidity sensor is performed as described with reference to FIG. This is the same as the case of the reference example described above (see steps 100 to 104 in FIG. 2).
[0020]
When the humidity is determined to be equal to or higher than the predetermined value in any of the air conditioners 3a to 3c of any of the rooms A to C, a control signal is sent from any of the air conditioners 3a to 3c to the corresponding ventilation controller 2a to 2c. A drive signal for driving the air supply ventilation fan 9 and the exhaust fan 10 is output from any of the ventilation controllers 2a to 2c. This drive signal starts the air supply ventilation fan 9 and the exhaust fan 10 via the controller 8, and the ventilation of each of the living rooms A to C is forcibly performed.
