Note that the operation device 5 may be provided integrally with a part of the management device 1 or the inwardly moving single sliding window device 3 or the like.

－Operating Modes of Natural Ventilation Window System－
The natural ventilation window system of this embodiment has an automatic operation mode in which the opening and closing of the internal sliding window device 3 is automatically controlled based on the opening and closing of the natural ventilation window device 2, and an internal sliding single sliding window device according to the user's operation. It is possible to set two electric opening/closing modes, a manual operation mode for controlling the opening/closing of the device 3, and a manual opening/closing mode for manually opening/closing the inwardly moving single sliding window device 3, and the single sliding window can be opened/closed in each mode. can.
The mode in the natural ventilation window system of the present embodiment means the method/style for opening and closing the internal sliding single sliding window device 3, and the method/style for opening and closing the window electrically and the method/style for opening and closing the window manually. Both the method and style of opening and closing are described as modes.

(automatic driving mode)
The automatic operation mode is an operation mode in which the opening and closing of the inward sliding sliding window device 3 is controlled according to the detection result of the detection device 4 and the opening and closing of the natural ventilation window device 2 .
In the automatic operation mode, the natural ventilation window system restricts the opening of the inward sliding sliding window device 3 and the natural ventilation window device 2 during bad weather such as strong wind and rain.

For example, when the wind speed sensor 401 inputs a signal indicating that the outdoor wind speed is equal to or higher than a predetermined wind speed, or when the rain sensor 402 inputs a signal indicating that rain has been detected, the management device 1 A closing process is executed and a closing instruction signal is output to the opening/closing window control unit 390 and the natural ventilation window control unit 290 .

The opening/closing window control unit 390 of the inwardly moving single sliding window device 3 that receives the closing instruction signal drives the electric motor device 340b in the closing direction. The driving of the electric motor device 340b in the closing direction is continued until the closing detection sensor 340d detects the closing of the inner shoji 320 and outputs a closed position signal indicating that the inner shoji 320 is in the closed position.

When the closing position signal output by the closing detection sensor 340d is input, the opening/closing window control unit 390 stops driving the electric motor device 340b and drives the electric crescent 360 in the locking direction to open the inward sliding single sliding window device 3. complete the closing process.

In addition, the natural ventilation window control unit 290 of the natural ventilation window 200 that receives the closing instruction signal drives the opening/closing electric motor 285 to rotate the opening/closing arm 240 in the closing direction, thereby forcibly closing the natural ventilation window 200. do. The driving of the opening/closing electric motor 285 is continued until the opening/closing detection sensor 260 of the natural ventilation window 200 outputs a closing signal indicating that the shoji 220 is closed.

The natural ventilation window control unit 290 stops driving the opening/closing electric motor 285 and drives the locking electric motor 286 of the lock device 250 in the locking direction when the closing signal output by the opening/closing detection sensor 260 is input. to complete the closing process of the natural ventilation window device 2.

Note that the natural ventilation window control unit 290 does not close and lock the natural ventilation window 200, but limits the opening angle depending on the degree of the signal from the wind speed sensor 401 or rainfall sensor 402 (such as the height of the wind speed). The opening/closing arm 240 may be driven as follows.

On the other hand, in the automatic operation mode, the natural ventilation window system opens and closes the internal sliding window device 3 according to the opening and closing of the natural ventilation window device 2 when the weather is fine.
For example, the management device 1 of the natural ventilation window system does not receive a signal from the wind speed sensor 401 indicating that the outdoor wind speed is above a predetermined value and a signal from the rainfall sensor 402 indicating that rain has been detected. When an open signal indicating that the natural ventilation window 200 has been opened is input from the opening/closing detection sensor 260 of No. 2, partial opening processing is executed to partially open the inward sliding single sliding window 300 to the opening/closing window control unit 390. Outputs an instruction signal.

The open/close window control unit 390 that receives the partially open instruction signal drives the electric motor device 340b in the closing direction for a predetermined time, and then drives the electric crescent 360 in the unlocking direction.

The opening/closing window control unit 390 drives the electric motor device 340b in the opening direction when the electric crescent 360 is unlocked. The drive of the electric motor device 340b in the opening direction is, as shown in FIG. This is continued until 340e outputs a partially open signal indicating that the inner shoji 230 is partially opened.

The opening/closing window control unit 390 stops driving the electric motor device 340b upon receiving the partially opened signal output by the partially opened detection sensor 340e, and completes the partially opened processing of the inner sliding single sliding window device 3. do.

In addition, since there is a possibility of a sudden change in the weather, in the automatic operation mode, the opening of the inner sliding single sliding window device 3 is limited to a partial opening (for example, an opening width (for example, about 300 mm) that is arbitrarily set in advance). Although it is preferable to keep it open, the inner shoji 320 may be kept open until it is fully opened.

(Hand operation mode)
The manual operation mode is an operation mode in which the user can open and close the internal sliding window device 3 using the operation device 5, and the internal sliding window 300 can be operated independently regardless of the open/closed state of the natural ventilation window 200. can be opened and closed.

The natural ventilation window system restricts the opening of the internal sliding window device 3 and the natural ventilation window device 2 in bad weather such as strong wind and rain in the manual operation mode.

For example, when the wind speed sensor 401 inputs a signal indicating that the outdoor wind speed is equal to or higher than a predetermined wind speed, or when the rain sensor 402 inputs a signal indicating that rain has been detected, the management device 1 A closing process is executed and a closing instruction signal is output to the opening/closing window control unit 390 and the natural ventilation window control unit 290 .

Since the user opens and closes the window in the manual operation mode, the window may be opened when it rains to some extent. Processing may be executed, and opening of the natural ventilation window device 2 and the inwardly moving single sliding window device 3 may be restricted.

The operation of the opening/closing window control unit 390 and the natural ventilation window control unit 290 during the closing process is the same as the operation during the closing process during the automatic operation mode, so the description thereof will be omitted here.

On the other hand, in the manual operation mode, the natural ventilation window system opens and closes the inward sliding single sliding window device 3 in accordance with the user's open/close instruction operation when the weather is fine.
For example, when a signal from the wind speed sensor 401 indicating that the outdoor wind speed is equal to or higher than a predetermined value is not input, when the user operates the "open button" displayed on the display screen of the operation device 5, the operation device 5 A release signal is output to the management device 1 .
The management device 1 that receives the shoji open signal executes a full open process and outputs a full open instruction signal to the open/close window control unit 390 .

The open/close window control unit 390 that receives the fully open instruction signal drives the electric motor device 340b in the closing direction for a predetermined time, and then drives the electric crescent 360 in the unlocking direction.

The opening/closing window control unit 390 drives the electric motor device 340b in the opening direction when the electric crescent 360 is unlocked. The driving of the electric motor device 340b in the opening direction is, as shown in FIG. This is continued until a full open signal indicating full open is output.

The opening/closing window control unit 390 stops driving the electric motor device 340b by inputting the full-open signal output by the full-open detection sensor 340f, and completes the full-opening process.

Note that the processing in the hand operation mode is such that the electric motor device 340b is driven only while the "open button" displayed on the display screen of the operation device 5 is being pressed by the user, and when the "open button" is released. The driving of the electric motor device 340b may be stopped immediately.

Further, when the user operates a “close button” displayed on the display screen of the operating device 5 , the operating device 5 outputs a shoji closing signal to the management device 1 .
The management device 1 that receives the shoji closing signal executes closing processing and outputs a closing instruction signal to the opening/closing window control unit 390 .

The operation of the opening/closing window control unit 390 during the closing process is the same as the operation during the closing process in the automatic operation mode, so the description thereof will be omitted here.

Further, when the user operates a “stop button” displayed on the display screen of the operation device 5 , the operation device 5 outputs an operation stop signal to the management device 1 .
The management device 1 that has received the operation stop signal executes stop processing and outputs a stop instruction signal to the opening/closing window control unit 390 .
Upon receiving the stop instruction signal, the opening/closing window control unit 390 stops driving the electric motor device 340b to complete the stop processing.

(Manual open/close mode)
In the natural ventilation window system, the user operates the operating lever 350c of the coupling device 350 downward to release the engagement between the piece member 340c of the shoji door opening/closing device 340 and the engaging portion 350b of the coupling device 350, thereby manually opening and closing the system. mode can be changed.
In the manual opening/closing mode, the natural ventilation window system can manually open the inner shoji 320 to any position as shown in FIG.

It is preferable to unlock the electric crescent 360 before shifting to the manual opening/closing mode by operating the operation lever 350c. The unlocking of the electric crescent 360 may be performed by automatic electric unlocking, or the electric crescent 360 may be unlocked manually.

With the electric crescent 360 unlocked, the inner shoji 320 can be opened by operating the operating lever 350c downward to move the inner shoji 320 leftward.
Further, by operating the operating lever 350c of the coupling device 350 upward after moving the inner shoji 320 to the closed position, it is possible to return to the automatic operation mode or the manual operation mode.

In addition, the inner shoji 320 opened in the manual opening/closing mode may be automatically closed after a predetermined period of time, for example.
For example, by moving the piece member 340c of the shoji door opening/closing device 340 to a position above the engaging portion 350b of the coupling device 350, the piece member 340c and the engaging portion 350b are automatically engaged, and the manual operation is performed. When the opening/closing mode has passed for a predetermined time or at a predetermined time, the opening/closing window control unit 390 drives the electric motor device 340b to move the piece member 340c to a position above the engaging portion 350b and engage the engaging portion 350b. A closing operation may then be performed.

－Opening and closing control in a natural ventilation window system－
An example of the control flow of the electric drive mode in the natural ventilation window system of this embodiment will be described with reference to the flow shown in FIG.

When the natural ventilation window system is powered on, in step S101, it checks whether the natural ventilation window system is in the automatic operation mode or the manual operation mode. The operation mode can be switched by the user selecting a mode selection button of “automatic operation button” or “hand operation button” displayed on the display screen of the tablet terminal (operation device) 5 .

(automatic driving mode)
When the automatic operation mode is selected, the natural ventilation window system proceeds to step S102 and checks whether the wind speed detected by the wind speed sensor 401 is equal to or greater than the threshold a.

If the wind speed detected by the wind speed sensor 401 is equal to or less than the threshold value a, the natural ventilation window system proceeds to step S103 and checks whether or not the rain sensor 402 has detected rain. The natural ventilation window system proceeds to step S107 when the wind speed detected by the wind speed sensor 401 is equal to or greater than the threshold value a in step S102 or when rain is detected by the rain sensor 402 in step S103.

On the other hand, if rain is not detected in step S103, the natural ventilation window system proceeds to step S104 and checks whether or not the natural ventilation window 200 is opened by the opening/closing detection sensor 260 of the natural ventilation window 200. However, when it is determined that the natural ventilation window 200 is open, the process proceeds to step S105, the inner sliding door 320 of the inner sliding single sliding window device 3 is driven to open, and the process returns to step S101.
On the other hand, if it is determined in step S104 that the natural ventilation window 200 is closed, the process proceeds to step S106 to drive the inner sliding single sliding window device 3 to be closed, and the process returns to step S101.

In step S107, the natural ventilation window system drives the inward sliding single sliding window device 3 to close.
The natural ventilation window system drives the inwardly moving single sliding window device 3 to close and counts the time, maintains the closed state until 30 minutes have elapsed, and returns to step S101 after 30 minutes have elapsed (step S108).

(Hand operation mode)
On the other hand, if the manual operation mode is selected, the natural ventilation window system proceeds to step S112 and checks whether the wind speed detected by the wind speed sensor 401 is equal to or greater than the threshold a.

When the wind speed detected by the wind speed sensor 401 is equal to or higher than the threshold value a, the natural ventilation window system proceeds to step S117 and drives the inward sliding single sliding window device 3 to close.
On the other hand, if the wind speed detected by the wind speed sensor 401 is equal to or less than the threshold a, the natural ventilation window system proceeds to step S113 and confirms the operation of the inward sliding single sliding window 300 selected by the user.

The natural ventilation window system drives the internally moving single sliding window device 3 to open when the operation of the internally moving single sliding window 300 selected by the user is the opening operation, and the operation of the selected internally moving single sliding window 300 is closed. If it is an operation, the inner-moving single-sliding window device 3 is driven to close, and if the operation of the selected inner-moving single-sliding window 300 is a stop operation, the inner-moving single-sliding window device 3 is driven to open or close. Stop and return to step S101.

In step S117, the natural ventilation window system that has closed the inner-moving single-sliding window device 3 drives the inner-moving single-sliding window device 3 to close and counts time, and then maintains the closed state until 30 minutes have passed. Then, the process returns to step S101 (step S118).
An example of the control flow of the electric drive mode in the natural ventilation window system of the present embodiment has been described above.
