In FIG. 3, the control device 200 of the automatic opening / closing device 1 has an opening / closing command unit 205 that generates an opening command signal when the opening button switch Wo is turned on and generates a closing command signal when the closing button switch Ws is turned on. The opening detection switch 221 as an opening detection means for detecting that the first and second windows 5 and 7 are opened and generating an opening detection signal, and the first and second windows 5 and 7 are provided. It is provided with a closing detection switch 222 as a closing detecting means for detecting closing and generating a closing detection signal. Here, the opening detection signal by the opening detection switch 221 is formed so as to be generated in a state where the first and second windows 5 and 7 are half-opened.

The control device 200 has a motor control unit 232 that drives the motor 21 via the motor drive unit 252 based on the opening command signal and stops the motor 21 based on the closing command signal, and has an opening detection signal. Drives the first and second ventilation fans 101 and 102 via the ventilation fan drive unit 254, and stops the first and second ventilation fans 101 and 102 via the ventilation fan drive unit 254 based on the closing detection signal. It is provided with a ventilation fan control unit 234. The AC power source e is input to the motor drive unit 252 and the ventilation fan drive unit 254.

Further, the control device 200 has an odor detection unit 260 that detects an odor inside the first and second windows 5 and 7 and generates an odor detection signal, and the odor detection value based on the odor detection signal is determined. It is provided with an opening determination unit 262 that generates an opening command signal while exceeding a predetermined odor value and generating a closing detection signal.

The operation of the automatic window opening / closing device having the ventilation fan and the curtain configured as described above will be described with reference to FIGS. 1 to 4.
<Operation from the closed state to the open window>
Now, when the release button switch Wo is pressed while the first and second windows 5 and 7 are closed (step S101), the open / close command unit 205 generates an open command signal (step S103). By rotating the motor 21 for the first time, the first and second ball screws 23 and 25 also rotate to move the first and second drive members 37 and 39, and the first and second windows 5 , 7 is moved in the opening direction (step S105). Eventually, when the first and second windows 5 and 7 reach a predetermined opening position, an opening detection signal is generated (step S107), and the motor control unit 232 uses the motor 21 via the motor drive unit 252. Is stopped (step S109).

The ventilation fan control unit 234 drives the first and second ventilation fans 101 and 102 via the ventilation fan drive unit 254 by the generation of the opening detection signal (step S111), and as shown in FIG. 2 (b), the outdoor and indoor areas. It is possible to reduce the odor in the room by circulating the air flow. Next, when the closing button switch Ws is pressed and a closing command signal is generated while the first and second ventilation fans 101 and 102 are being driven (step S113), the ventilation fan control unit 234 moves the ventilation fan. It stops via the drive unit 254 (step S115).

<Operation from open window to closed window>
Next, when the closing button switch Ws is pressed while the first and second windows 5 and 7 are open (step S101), the open / close command unit 205 generates a closing command signal (step S103). ), By rotating the motor 21 in the second direction opposite to the first rotation, the first and second ball screws 23 and 25 also rotate to move the first and second drive members 37 and 39. , The first and second windows 5 and 7 are moved in the closing direction (step S105). Eventually, when the first and second windows 5 and 7 reach a predetermined closing position, a closing detection signal is generated (step S117), and the motor control unit 232 passes through the motor drive unit 252. The motor 21 is stopped (step S119).

<Operation from the closed state to the open state of the window when the odor value exceeds the threshold value>
Now, in a state where the first and second windows 5 and 7 are closed, the open determination unit 262 sets the odor detection value based on the odor detection signal to exceed a predetermined odor value and also causes the closing detection signal. When is generated, an open command signal is generated (step S201). After that, the above steps S105 to S115 are executed to end the process.

Embodiment 2.
Other embodiments of the present invention will be described with reference to FIG. In FIG. 5, in the fixing release means, the first and second coils 137c and 139c are formed on the first and second drive members 137 and 139, which are L-shaped and columnar, respectively, and the switch SWc for the electromagnet is formed via the resistor 121. When the current is turned on, a current is passed from the DC power supply E, and the first and second drive members 137 and 139 become electromagnets, and the suction portions 137t and 139t of the first and second drive members 137 and 139 are the first and second. The liner 17 connected and fixed to the upper ends of the curtains 11 and 12 is attracted and fixed, and the current is cut off from the DC power supply E by turning off the electromagnet switch SWc to release the fixing. There is. Thereby, the movement of the first and second windows 3 and 5 and the movement of the first and second curtains 11 and 12 can be selected synchronously or asynchronously by turning on or off the switch SWc for the electromagnet.

The present invention is not limited to the description of the embodiments of the present invention. Various modifications are also included in the present invention to the extent that those skilled in the art can easily conceive without departing from the description of the scope of claims. For example, the automatic window opening / closing device 1 has the first and second ventilation fans 101 and 102, but may include either one of the first or second ventilation fans 101 and 102. In step 113 of FIG. 4, the first and second ventilation fans 101 and 102 were stopped due to the generation of the closing command signal (step 115), but in FIG. 1, the push button switch for stopping the ventilation fan was closed. When the push button switch is provided in the vicinity of Ws and the open button switch Wo, the ventilation fan control unit 234 may stop the first and second ventilation fans 101 and 102 via the ventilation fan drive unit 254. ..
