<First embodiment>
A ventilation system 100 in this embodiment will be described with reference to FIGS. When the range hood 10 is operated for the purpose of taking in outside air from the opening of the building HS in order to bring the indoor air quality of the building HS (the house in this embodiment) closer to the outdoor air quality, the ventilation system 100 is used in a living room of the house. When it is not preferable from the viewpoint of crime prevention, such as leaving the window open, the range hood 10 is interlocked with fittings (windows, shutters, etc.) located at the opening. The cooker hood 10 is provided above the stove BN installed in the kitchen, and sucks the air containing oily smoke and the like generated when cooking on the stove BN and discharges it to the outside, thereby diffusing the oily smoke indoors. to prevent The range hood 10 in the ventilation system 100 functions as such a normal range hood, and also functions to bring the indoor air quality closer to the outdoor air quality.

In this specification, air quality refers to substances that make up air (for example, oxygen, carbon monoxide, carbon dioxide, etc.), substances contained in air (for example, moisture, oil, dust, odorous substances, etc.). or gaseous), an index (temperature) that indicates the kinetic energy of air, etc., and is a concept that indicates the quality of air that humans can feel or be affected by. Air quality is generally measured as temperature, humidity, carbon monoxide concentration, pollutant concentration, etc. using detectors (sensors) corresponding to each air quality.

The cooker hood 10 is installed near cooking utensils (stove BN, etc.) usually installed in the kitchen, and is used to collect substances such as oily smoke generated from cooking with a large exhaust air volume and discharge it to the outside. . When the range hood 10 discharges the air in the kitchen to the outside with a large exhaust air volume, the pressure inside becomes negative, so outside air is taken into the room through the openings of the building such as the windows of the living room and bedroom. Then, the outdoor air replaces and mixes with the indoor air, so that the indoor air quality gradually approaches the outdoor air quality. The inventors used this phenomenon to improve indoor air quality, including in living spaces other than the kitchen, as a new method of using range hoods, which have the largest exhaust air volume among exhaust fans installed in general houses. proposes a ventilation system 100 including a range hood 10 for achieving

On the other hand, such a new usage of the range hood 10 is also assumed to be performed remotely when the person living in the house is not at home. It is not preferable from the viewpoint of crime prevention to leave the window of the living room of the house open at night, or to live alone even if the person is at home. In view of this problem, the range hood 10 receives instructions from a controller 20 (control unit), which will be described later, and operates in conjunction with the window 40 and the shutter 30 at the opening.

The ventilation system 100 includes a range hood 10 installed inside the building HS, an electric window 40 provided in the building HS whose opening and closing can be controlled, and an electric shutter 30 provided outside the window 40 whose opening and closing can be controlled. , a screen door 50 located between the window 40 and the shutter 30, a controller 20 for controlling the range hood 10, the shutter 30 and the window 40, and a notification unit 60 for notifying the user. As shown in FIG. 2, the range hood 10 includes an RH control unit 11 that controls its own operation, an RH communication unit 13 that communicates with the controller 20, and an operation unit 12 that receives operations from the user. The RH control unit 11 starts/stops operation when a user operates an operation start/stop button or the like of the operation unit 12, and receives an operation start signal/operation stop signal from the controller 20 via the RH communication unit 13. Then start/stop operation.

The window 40 is an electrically operated window that can be opened and closed and is provided in the building HS. The window 40 includes a window communication section 43 that communicates with the controller 20 , a window drive section 42 that drives opening and closing of the window 40 , and a window position detection section 41 that detects the position of the window 40 . The window position detection unit 41 detects whether the window 40 is closed or open, and if it is open, how much it is open, and if it is a sliding window, which window is open. Then, the detection information is transmitted to the controller 20 via the window communication unit 43 . Upon receiving an open signal for opening the window 40 or a close signal for closing the window 40 from the controller 20 via the window communication unit 43 , the window driving unit 42 drives the window 40 to open and close it.

The shutter 30 is an electrically operated shutter that is provided outside the window 40 and can be opened and closed, and has a vent hole 39 for ensuring ventilation even when the shutter 30 shown in FIG. 12 is closed. The shutter 30 includes an SH communication unit 35 that communicates with the controller 20, an SH driving unit 32 that drives the opening and closing of the shutter 30, an SH position detection unit 31 that detects the position of the shutter 30, and drives opening and closing of the vent 39. and a vent driver 34 that The SH position detection unit 31 detects whether the shutter 30 is closed, whether it is open, and if it is open, to what extent it is open, and transmits these detections to the controller 20 via the SH communication unit 35. Send information. Upon receiving an open signal for opening the shutter 30 or a close signal for closing the shutter 30 from the controller 20 via the SH communication section 35, the SH driving section 32 drives the shutter 30 to open and close it. The vent driver 34 opens and closes the vent 39 by opening and closing a louver 38 provided in front of the vent 39 . Upon receiving an open signal for opening the louver 38 or a close signal for closing the louver 38 from the controller 20 via the SH communication section 35 , the vent driving section 34 drives the louver 38 to open and close the vent 39 .

A screen door 50 is provided so as to be positioned between the window 40 and the shutter 30 . The screen door 50 includes a screen door communication unit 52 that communicates with the controller 20 and a screen door position detection unit 51 that detects the position of the screen door 50 . The screen door position detection unit 51 detects the position of the screen door 50 and transmits this detection information to the controller 20 via the screen door communication unit 52 . When the window 40 is a sliding window, the screen door 50 has a desirable position and an undesirable position depending on the positional relationship with the window 40, as shown in FIG.

In this figure (A1), since the left window 40 is open and the screen door 50 is in contact with the left window frame FL, the screen door 50 is properly closed. In this figure (A2), the window 40 on the right side is open and the screen door 50 is in contact with the window frame FL on the right side, so the screen door 50 is properly closed. In this figure (A3), the screen door 50 is properly closed because the window 40 on the right side is about half open and the screen door 50 is in contact with the window frame FL on the right side. This figure (A1) to (A3) is the most desirable state. In this figure (A4), the screen door 50 is properly closed because the left window 40 is about half open and the screen door 50 is in contact with the left window frame FL. However, since there is a gap between the screen door 50 and the left window 40, there is room for small insects and the like to enter through the gap.

In this figure (B1), the window 40 is closed, but since the screen door 50 is not in contact with either the left or right window frame FL, it cannot be said that the screen door 50 is in the proper position. In this figure (B2), the left window 40 is open and the screen door 50 is not in contact with either the left or right window frame FL, so it cannot be said that the screen door 50 is in the proper position. In this figure (B3), the left window 40 is open about 80% and the screen door 50 is not in contact with either the left or right window frame FL, so the screen door 50 is in the proper position. Absent. In this figure (B4), the window 40 on the right side is about 80% open and the screen door 50 is not in contact with either the left or right window frame FL. Absent. Therefore, it can be said that the screen door 50 in FIGS. (A1) to (4) is in a desirable position, but it can be said that the screen door 50 in (B1) to (B4) is in an undesirable position.

The detection methods of the SH position detection unit 31, the window position detection unit 41, and the screen door position detection unit 51 described above are detected by a known position detection method for this kind of fittings. Similarly, the SH drive section 32 and the window drive section 42 are driven by a known drive method for fittings of this type.

The notification unit 60 notifies people indoors by one or both of visual stimulation (such as blinking of a lamp, etc.) and auditory stimulation (such as ringing of a buzzer, etc.). In this embodiment, the notification unit 60 is provided integrally with the controller 20, but the notification device may be provided separately. The notification unit 60 notifies the user when the screen door 50 is not in the proper position.

The controller 20 (control unit) communicates with the range hood 10, the shutter 30, the window 40, the screen door 50, and the notification unit 60, collects detection information, and performs control. Also, the controller 20 communicates with an operation terminal TM located indoors or outdoors (including remote ones), and transmits detection information, notification information, and the like, and receives instruction signals. The controller 20 has a communication section 21 for communicating with the above. The communication unit 21 has a function of communicating with the remote operation terminal TM, a function of communicating with the RH communication unit 13, a function of communicating with the SH communication unit 35, a function of communicating with the window communication unit 43, and a screen door communication unit. 52 and a function of communicating with the notification communication unit 61 . Each communication function in the communication unit 21 is not particularly limited, and is appropriately executed by a known communication technique.

The controller 20 includes a microprocessor that performs various arithmetic processing, a control program such as an OS (Operating System), a program that defines various processing procedures, a memory for storing required data, predetermined air quality conditions, etc., communication A network interface and the like constituting the unit 21 are connected to each other via an internal bus or the like. Functions constituting the controller 20 are realized in cooperation with these hardware.

Since the range hood 10 has the ability to exhaust air with a large amount of exhaust air, the indoor pressure becomes negative when the air is exhausted to the outside, and the outside air is taken into the indoor from the opening of the building HS (for example, the open window 40). Then, the outdoor air replaces and mixes with the indoor air, so that the indoor air quality gradually approaches the outdoor air quality. The ventilation system 100 can also improve indoor air quality, including living spaces other than the kitchen, by using this phenomenon.

For example, before returning home, the user operates the operation terminal TM from a place away from the building HS to start the operation of the range hood 10 in order to improve the indoor air quality (e.g. temperature) of the building HS. Like, I give instructions on a midsummer night. In a room that is very hot and sunny during the day, the greenhouse effect can cause the indoor temperature to be very high. Then, in the evening, it rained due to a shower, etc., and the outdoor temperature dropped, but the indoor temperature did not drop so much if the windows were closed and the heat was trapped. In such a case, the range hood 10 having a large exhaust air volume is used to exhaust hot indoor air and take in relatively cool outdoor air, thereby gradually bringing the indoor temperature closer to the outdoor temperature. can be done. As a result, when the user returns home to the building HS, the interior is in a relatively cool state with no heat buildup.

In this case, taking in outdoor air through a large opening such as the window 40 is highly effective, but opening the window 40 when the user is not present is not preferable for crime prevention. Therefore, the controller 20 of the ventilation system 100 receives a signal for starting the operation of the range hood 10 from the operation terminal TM, and when controlling the start of the range hood 10, controls the shutter 30 to be in a closed state. The closed state of the shutter 30 is a state in which the shutter 30 is completely lowered and an intruder cannot enter through the opened window 40 . The controller 20 transmits a close signal to the SH drive unit 32 via the communication unit 21 and the SH communication unit 35, and the SH drive unit 32 that receives the close signal drives the shutter 30 to close. In this way, by controlling the shutter 30 to be in a closed state when controlling the start of operation of the range hood 10, the range hood for improving the indoor air quality including the living space other than the kitchen. In the ventilation system 100 including 10, the ventilation system 100 with good security can be provided.

Since the shutter 30 has a vent 39 for taking in outdoor air, the controller 20 drives a louver 38 for opening the vent 39 when the shutter 30 is closed. The signal may be sent to vent driver 34 via communication unit 21 and SH communication unit 35 . Thus, when the shutter 30 is provided with the vent 39, by controlling the vent 39 to be in an open state, it is possible to improve air quality while maintaining security.

Further, when controlling the start of operation of the range hood 10, the controller 20 preferably operates to open the window 40 that can be controlled to open and close and to close the shutter 30. FIG. The controller 20 transmits an open signal to the window driving section 42 via the communication section 21 and the window communication section 43 . To open the window 40 means to open the closed window 40 to some extent to form an opening through which outdoor air flows. Thus, when the window 40 can be controlled to open and close, by controlling the window 40 to open and the shutter 30 to close, high security is ensured even during the opening and closing operations of the shutter 30 and the window 40. can. Either the timing of opening the window 40 or the timing of closing the shutter 30 may come first. Control is preferred. Thus, by controlling the shutter 30 to be closed and completely closed before the window 40 is opened, high security can be ensured even during opening and closing operations of the shutter 30 and the window 40. .

Further, it is preferable that the controller 20 does not open the window 40 when the screen door 50 is not at the position corresponding to the window 40 to be opened. For example, as shown in FIG. 13 (A1), when the sliding window on the left side is open, if the screen door 50 is on the left side, the window 40 is opened, but if the screen door 50 is on the right side, the window 40 is opened. Do not open. Conversely, as shown in FIG. 13A2, when the sliding window on the right side is open, the window 40 is opened if the screen door 50 is on the right side, but if the screen door 50 is on the left side, the window 40 is opened. Do not leave open. In this way, when there is no screen door 50 at the position corresponding to the window 40 to be opened, the window 40 is not opened, so that crime prevention as well as insect resistance can be ensured. In addition, when there is no screen door 50 at the position corresponding to the window 40 to be in the open state, the notification unit 60 may notify the user to that effect.

A processing flow of the controller 20 in the ventilation system 100 will be described with reference to FIGS. 3 to 7. FIG. Note that ST in the flow chart means a step. FIG. 3 shows the main flow of shutter-linked ventilation control. In ST100, the controller 20 receives a signal for starting operation of the range hood 10 (ventilation start signal) from the operation terminal TM. Then, the controller 20 confirms the states of the shutter 30, the vent 39, the window 40, and the screen door 50 in ST200.

More specifically, as shown in FIG. 4, the controller 20 acquires the state of the shutter 30 detected by the SH position detection section 31 via the communication section 21 and the SH communication section 35 in ST202. Check whether it is in the closed state. If the shutter 30 is not closed, the controller 20 turns on the shutter closed flag in ST210. If the shutter 30 is closed, nothing is done. In ST204, the controller 20 similarly acquires the state of the vent 39 detected by the vent opening/closing detector (not shown), and checks whether the vent 39 is open. If the vent 39 is not open, the controller 20 turns on the vent open flag in ST212. If the vent 39 is open, do nothing.

In ST206, the controller 20 acquires the state of the window 40 detected by the window position detection section 41 via the communication section 21 and the window communication section 43, and checks whether the window 40 is open. If the window 40 is not open, the controller 20 turns on the window open flag in ST214. If the window 40 is open, do nothing. In ST208, the controller 20 acquires the state of the screen door 50 detected by the screen door position detection section 51 via the communication section 21 and the screen door communication section 52, and checks whether or not the screen door 50 is in the proper position. If the screen door 50 is not in the proper position, the controller 20 turns on the improper position flag in ST216. If the screen door 50 is in the proper position, nothing is done.

After confirming each state, the controller 20 notifies in ST300 that the screen door 50 is in an inappropriate position. More specifically, as shown in FIG. 5, the controller 20 checks in ST302 whether or not the improper position flag is ON. If it is ON, in ST304, the controller 20 instructs the notification section 60 to notify that the screen door 50 is in the improper position. Thereby, the notification unit 60 performs notification. If the screen door 50 is in an improper position, the controller 20 checks the state of the screen door 50 and the like in ST200 without performing the following processing, and if the screen door 50 is in an appropriate position, performs the following processing. As a result of confirming the state of the screen door 50, even when it is detected that the screen door 50 is closed, the operation is restarted and the following processing is performed.

In ST400, the controller 20 performs opening/closing control processing of the shutter 30, the vent 39, and the window 40 before operating the range hood 10. FIG. More specifically, as shown in FIG. 6, the controller 20 checks whether the shutter closing flag is ON in S402. If the shutter closing flag is ON, that is, if the shutter 30 is open, in ST404, the shutter 30 is controlled to be closed. That is, the controller 20 instructs the SH driving section 32 to perform the closing operation via the communication section 21 and the SH communication section 35 . If the shutter closing flag is not ON, the controller 20 does nothing. Note that the controller 20 does not need to close the shutter 30 during the daytime. On the contrary, the closing of the shutter 30 may pose a security problem. Also, the controller 20 may control the lighting in the room facing the shutter 30 to be dark at night.

In S406, the controller 20 checks whether the vent open flag is ON. If the vent open flag is ON, that is, if the vent 39 is not in the open state, in ST408 the vent 39 is controlled to be in the open state. That is, the controller 20 instructs the vent driving section 34 to open via the communication section 21 and the SH communication section 35 . If the vent open flag is not ON, the controller 20 does nothing. In S410, the controller 20 checks whether the window open flag is ON. If the window open flag is ON, that is, if the window 40 is not in the open state, the window 40 is controlled to be in the open state in ST412. That is, the controller 20 instructs the window driving section 42 to open via the communication section 21 and the window communication section 43 . If the window open flag is not ON, the controller 20 does nothing. The controller 20 clears the shutter closed flag, vent open flag, and window open flag in ST414.

After performing each opening/closing control, the controller 20 controls the start of operation of the range hood 10 in ST500. That is, the controller 20 instructs the RH control section 11 via the communication section 21 and the RH communication section 13 to rotate the exhaust fan (not shown) to operate the range hood 10 . Thereby, the ventilation system 100 improves the indoor air quality including the living space other than the kitchen.

After starting the operation of the range hood 10, the controller 20 stops the operation of the range hood 10 under a predetermined condition. The predetermined conditions are, for example, when a predetermined time has passed, when a stop instruction is received from the operation terminal TM, when the indoor air quality approaches the outdoor air quality, and the like. After stopping the operation of the range hood 10, the controller 20 performs opening/closing control processing after stopping the range hood in ST600. More specifically, as shown in FIG. 7, in ST602, the controller 20 waits for whether or not the predetermined condition is satisfied and the operation of the range hood 10 is to be stopped. When the operation is stopped, the controller 20 causes the window driving section 42 to close the window 40 in ST604. In ST606, the controller 20 causes the vent driver 34 to close the vent 39 . Further, the controller 20 causes the SH driving section 32 to open the shutter 30 in ST608. In this manner, the controller 20 preferably controls the window 40 to be closed before opening the shutter 30 . According to this, it is possible to ensure high crime prevention even during the opening and closing operations of the shutter 30 and the window 40. - 特許庁Also, the shutter 30 does not have to be opened.

<Second embodiment>
A ventilation system 100A in this embodiment will be described with reference to FIGS. 1, 3 and 8 to 11. FIG. In order to avoid redundant description, the same elements are denoted by the same reference numerals and their description is omitted, and the description will focus on the differences from the above embodiment. The ventilation system 100A keeps the window of the living room of the house open when the range hood 10 is operated for the purpose of taking in outside air from the opening of the building HS in order to bring the indoor air quality of the building HS closer to the outdoor air quality. When it is not preferable in terms of crime prevention, such as when the door is closed, the range hood 10 and fittings (shutters) positioned at the opening are interlocked.

The ventilation system 100A includes a range hood 10 installed inside the building HS, a manually openable and closable window 40A provided in the building HS, an electric shutter 30 provided outside the window 40A and capable of opening and closing, A screen door 50 positioned between the window 40A and the shutter 30, a controller 20A for controlling the range hood 10 and the shutter 30, and a notification unit 60 for notifying the user are provided. As shown in FIG. 8, the window 40A is of a manual type, so it does not have the window driving section 42 that was provided in the first embodiment.

The window 40A includes a window communication section 43 that communicates with the controller 20A, and a window position detection section 41 that detects the position of the window 40A. The window position detection unit 41 detects whether the window 40A moved by the user is closed, whether it is open, if it is open, how much it is open, and if it is a sliding window, which window is open. It detects whether it is on or off, and transmits this detection information to the controller 20A via the window communication unit 43.

A processing flow of the controller 20A in the ventilation system 100A will be described with reference to FIGS. 3 and 9 to 11. FIG. In ST100, the controller 20A receives a signal for starting operation of the range hood 10 (ventilation start signal) from the operation terminal TM. Then, in ST200, the controller 20A confirms the states of the shutter 30, the air vent 39, and the window 40A.

More specifically, as shown in FIG. 9, the controller 20A acquires the state of the shutter 30 detected by the SH position detection unit 31 via the communication unit 21 and the SH communication unit 35 in ST202A. Check whether it is in the closed state. If the shutter 30 is not closed, the controller 20A turns on the shutter closed flag in ST208A. If the shutter 30 is closed, nothing is done. In ST204A, the controller 20A similarly acquires the state of the vent 39 detected by the vent opening/closing detector, and checks whether the vent 39 is open. If vent 39 is not open, controller 20A turns on the vent open flag in ST210A. If the vent 39 is open, do nothing.

In ST206A, controller 20A acquires the state of window 40A detected by window position detection section 41 via communication section 21 and window communication section 43, and checks whether window 40A is open. If the window 40A is not open, the controller 20A turns on the improper position flag in ST212A. Nothing is done when the window 40A is open.

After confirming each state, the controller 20A notifies in ST300 that the window 40A is in an inappropriate position. That is, the controller 20A causes the window position detection unit 41 to detect the position of the window when controlling the start of operation of the range hood 10, and when the window position detection unit 41 detects that the window is closed, the controller 20A notifies The unit 60 notifies that the window is closed. The controller 20A confirms the state of the window 40A, etc. in ST200 without performing the following processing when the window 40A is in the improper position, and performs the following processing when the window 40A is in the proper position.

Controller 20A performs opening/closing control processing of shutter 30 and vent 39 before operating range hood 10 in ST400A. More specifically, as shown in FIG. 10, the controller 20A checks whether the shutter closing flag is ON in S402A. If the shutter closing flag is ON, that is, if the shutter 30 is open, in ST404A, the shutter 30 is controlled to be closed. If the shutter closing flag is not ON, the controller 20A does nothing.

The controller 20A checks in S406A whether or not the vent open flag is ON. If the vent open flag is ON, that is, if the vent 39 is not in the open state, in ST408A, the vent 39 is controlled to be in the open state. If the vent open flag is not ON, the controller 20A does nothing. The controller 20A clears the shutter closed flag and the vent open flag in S410A.

After performing each opening/closing control, the controller 20A controls the start of operation of the range hood 10 in ST500. That is, the controller 20A instructs the RH control section 11 via the communication section 21 and the RH communication section 13 to operate the range hood 10 by rotating the exhaust fan. Thereby, the ventilation system 100A improves the indoor air quality including the living space other than the kitchen.

After starting the operation of the range hood 10, the controller 20A stops the operation of the range hood 10 under a predetermined condition. When the operation of the range hood 10 is stopped, the controller 20A performs opening/closing control processing after the range hood is stopped in ST600A. More specifically, as shown in FIG. 11, the controller 20A waits in ST602A to determine whether the predetermined condition is satisfied and the operation of the range hood 10 is to be stopped. When the operation is stopped, the controller 20A causes the vent driving section 34 to close the vent 39 in ST604A. Further, the controller 20A causes the SH driving section 32 to open the shutter 30 in ST606A.

As described above, when the window position detection unit 41 detects that the window 40A is closed, the notification unit 60 notifies that the window is closed. As a result of the confirmation, when the window position detection unit 41 detects that the window 40A is open, the shutter 30 may be controlled to be closed. Thus, when the window 40A is manually operated, the user is notified when the window 40A is closed, and when the user opens the window 40A, the shutter 30 is controlled to close. As a result, even with the manual window 40A, it is possible to improve the indoor air quality and ensure high security.
