Description

  The technology disclosed herein relates to a ventilation system.

  The ventilation system disclosed in Patent Literature 1 includes a ventilator that ventilates indoor air, a cooking device that is disposed indoors, and a controller. The ventilator is operable based on signals received from the cooking device and signals received from the controller.

JP 2014-228217 A

  In the configuration as in Patent Document 1, the ventilation device can operate based on the signal received from the cooking device and the signal received from the controller, and thus the air volume of the ventilation device may change frequently. For example, if the ventilator operates based on a signal received from the cooking device, then operates based on a signal received from the controller, and then operates again based on a signal received from the cooking device, the ventilation device The air volume changes frequently. Therefore, the present specification provides a technique capable of preventing frequent changes in the air volume of the ventilator.

  The ventilation system disclosed in this specification includes a ventilation device that ventilates indoor air, and a first indoor device and a second indoor device that are arranged indoors. The ventilator is operable based on a first signal transmitted by the first indoor device and a second signal transmitted by the second indoor device, and has received the first signal transmitted by the first indoor device. In the case of operating based on the first signal and not receiving the first signal transmitted by the first indoor device, the second signal when receiving the second signal transmitted by the second indoor device. It is possible to operate based on

  According to such a configuration, since the ventilation device always operates based on the first signal when receiving the first signal transmitted from the first indoor device, the air volume of the ventilation device does not change frequently. For example, even if the second signal transmitted by the second indoor device is received thereafter, the operation is not performed based on the second signal. Or after receiving the 1st signal which the 1st indoor unit transmits, the composition which cannot receive the 2nd signal which the 2nd indoor unit transmits may be sufficient. In other words, after receiving and operating the first signal transmitted by the first indoor device, the second indoor device does not operate based on the second signal transmitted. On the other hand, when the 1st signal which the 1st indoor unit transmits is not received, when the 2nd signal which the 2nd indoor unit transmits is received, it can operate based on the 2nd signal. Thereafter, when the first signal transmitted from the first indoor device is received, the operation is performed based on the first signal. Thus, since the operation based on the first signal transmitted by the first indoor device is prioritized, it is possible to prevent the air volume of the ventilation device from changing frequently.

  In said ventilation system, when the said ventilation apparatus is operate | moving based on the 1st signal which the said 1st indoor apparatus transmits, communication between the said ventilation apparatus and the said 2nd indoor apparatus may be restrict | limited. .

  According to such a configuration, since transmission / reception of the second signal is restricted, it is possible to prevent the ventilator from erroneously operating based on the second signal.

  The first indoor device and the second indoor device can communicate with each other. The ventilator may be capable of receiving a first signal from the first indoor device in a normal state while receiving a second signal through the first indoor device. Alternatively, the ventilator may be capable of receiving the second signal from the second indoor device in a normal state while receiving the first signal through the second indoor device. In the normal state, the ventilator may be operable based on a signal received from a device that relays the signal regardless of the order of reception of the first signal and the second signal. The ventilator may be configured to transmit the first signal to the first indoor device without relaying the first indoor device in a non-normal state in which communication between the first indoor device and the second indoor device is restricted. And the second signal may be received from the second indoor device without relaying the first indoor device. In a non-normal state, the ventilator operates based on the first signal when receiving the first signal transmitted by the first indoor device, and receives the first signal transmitted by the first indoor device. If not, the second indoor device may be operable based on the second signal when receiving the second signal transmitted.

  According to such a structure, the channel which a ventilator receives a signal at the time of normal can be unified. Further, even if communication between the first indoor device and the second indoor device is restricted during an abnormal time, the ventilator can receive a signal, and the air volume of the ventilator is operated so as not to change frequently. be able to.

  The ventilator may communicate with the first indoor device using a first communication method, and may communicate with the second indoor device using a second communication method.

  According to such a configuration, the first signal and the second signal received by the ventilator can be clearly distinguished by distinguishing the communication method.

  In the ventilation system, when the first indoor device and the second indoor device cannot communicate with each other, the second indoor device may transmit a third signal when a predetermined condition is satisfied. In addition, when the ventilation device receives the third signal transmitted by the second indoor device, the ventilation device converts the third signal into the third signal even if the first signal transmitted by the first indoor device is received. May operate based on.

  According to such a configuration, for example, when the user selects to temporarily give priority to the second indoor device, the second indoor device transmits the third signal having a high priority, whereby the second indoor device The ventilation operation based on can be executed with priority. As a result, it is possible to cause the ventilator to execute a ventilation operation reflecting the user's intention.

  The first indoor device may be a cooking device, and the second indoor device may be an air quality detection device that detects the air quality in the room. Moreover, the said heating cooking apparatus may be arrange | positioned under the said ventilation apparatus.

  According to such a configuration, it is possible to preferentially ventilate the periphery of the cooking device.

  In addition, when the detected indoor air quality is unsafe according to a predetermined safety standard, the air quality detection device may transmit an unsafe signal for specifying the fact. Moreover, the said ventilation apparatus is based on an unsafe signal, even when it is a case where the 1st signal which the said heating cooking apparatus receives is received when the unsafe signal which the said air quality detection apparatus transmits is received. May operate.

  According to such a configuration, when the indoor air quality is unsafe, priority is given to the unsafe signal transmitted by the air quality detection device, and the ventilator operates based on the unsafe signal. Thereby, the indoor air quality can be maintained in a safe state.

It is a figure for demonstrating the 1st operation | movement of 1st Example of a ventilation system. It is a figure for demonstrating the 2nd operation | movement of 1st Example of a ventilation system. It is a figure for demonstrating operation | movement of 2nd Example of a ventilation system.

  A ventilation system 1 according to an embodiment will be described with reference to the drawings. As shown in FIG. 1, the ventilation system 1 according to the embodiment includes a gas stove 20 (an example of a heating cooking device as one of the first indoor devices) and a sensor 40 (an air quality as one of the second indoor devices). An example of a detection device) and a range hood 30 (an example of a ventilation device) are provided.

  This ventilation system 1 is installed, for example, in a room 9 in a condominium or a detached house. The room 90 of the room 9 is divided into a kitchen area 91 and a dining area 92. In the kitchen area 91, the user U can perform cooking. In the dining area 92, the user U can eat.

  The gas stove 20 is disposed in the kitchen area 91 in the room 90. The gas stove 20 is disposed below the range hood 30. The gas stove 20 is a device for cooking by heating using a thermal power obtained by burning gas. The gas stove 20 includes a burner 21, an operation unit 22, and a communication unit 23. The gas stove 20 is cooked by the heating power of the burner 21.

  The operation unit 22 is configured so that the user U of the gas stove 20 can switch between ignition and extinguishing. Further, the operation unit 22 is configured to be able to switch the heating power of the burner 21 to “weak”, “medium”, and “strong”. The user U can switch the heating power of the gas stove 20 by operating the operation unit 22.

  The gas stove 20 can perform wireless communication via the communication unit 23. The gas stove 20 can transmit information regarding the operating state of the gas stove 20 to the range hood 30 via the communication unit 23. For example, the gas stove 20 can transmit information on ignition / extinguishment and information on thermal power “weak”, “medium”, and “strong” to the range hood 30.

  The sensor 40 is a device that detects the air quality in the room 90. The sensor 40 continuously detects the air quality in the room 90. The sensor 40 is disposed in the kitchen area 91 in the room 90. The sensor 40 includes a communication unit 43, and can perform wireless communication via the communication unit 43. The sensor 40 can transmit information regarding the air quality of the room 90 to the range hood 30 via the communication unit 43. For example, the sensor 40 can transmit information on “slightly bad”, “bad”, “very bad”, and “safe” / “unsafe” information of air quality, which will be described later, to the range hood 30.

  The sensor 40 can classify the air quality in the room 90 into “safe” and “unsafe” according to a predetermined safety standard. Further, when the air quality in the room 90 is “safe”, the sensor 40 can further classify it into four categories of “normal”, “slightly bad”, “bad”, and “very bad”. For example, when the user U is cooking with the gas stove 20 and smoke is generated, and the air quality of the room 90 is deteriorated, the sensor 40 classifies the detected air quality of the room 90 as “bad”. To do. Further, for example, when a strange odor is generated from a trash box (not shown) in the kitchen area 91 and the air quality of the room 90 is very deteriorated, the sensor 40 makes the detected air quality of the room 90 “very bad”. Classify. In addition, for example, when combustion exhaust gas is generated from the gas stove 20 and the air quality in the room 90 becomes unsafe, the sensor 40 classifies the detected air quality in the room 90 as “unsafe”. The state in which the air quality in the room 90 is unsafe is a state in which the air quality in the room 90 is deteriorated to such an extent that the physical condition of the user U in the room 90 is deteriorated, for example.

  The range hood 30 is a device that ventilates the air in the room 90. The range hood 30 is disposed in the kitchen area 91 of the room 90. The range hood 30 is disposed above the gas stove 20. The range hood 30 includes a fan 31, an operation unit 32, a communication unit 33, and a control unit 35. The control unit 35 controls the operation of the range hood 30.

  The fan 31 is rotated by the rotation of the motor and sends the air in the room 90 to the outside. When the rotation speed of the fan 31 changes, the air volume of the range hood 30 changes.

  The operation unit 32 is configured such that the user U can switch the range hood 30 on and off. Further, the operation unit 32 is configured to be able to switch the air volume of the range hood 30 to “weak”, “medium”, and “strong”. The user U can switch the air volume of the range hood 30 by operating the operation unit 32.

  The range hood 30 is configured to be capable of wireless communication via the communication unit 33. The communication unit 33 of the range hood 30 communicates wirelessly with the communication unit 23 of the gas stove 20. The range hood 30 receives information regarding the operating state of the gas stove 20 from the gas stove 20 via the communication units 33 and 23. The communication unit 33 of the range hood 30 communicates wirelessly with the communication unit 43 of the sensor 40. The range hood 30 receives information related to the air quality of the room 90 from the sensor 40 via the communication units 33 and 43.

  The communication unit 33 of the range hood 30 and the communication unit 23 of the gas stove 20 perform wireless communication by an infrared communication method (an example of a first communication method). The communication unit 33 of the range hood 30 and the communication unit 43 of the sensor 40 communicate wirelessly by a Bluetooth (registered trademark) communication method (an example of a second communication method). In the ventilation system 1 of the present embodiment, the infrared communication method between the range hood 30 and the gas stove 20 is a communication method having a higher priority than the Bluetooth communication method between the range hood 30 and the sensor 40. The infrared communication method is a primary communication method, and the Bluetooth communication method is a secondary communication method.

  Further, in the ventilation system 1 of the present embodiment, the gas stove 20 has a higher priority than the sensor 40. The gas stove 20 is a primary indoor device, and the sensor 40 is a secondary indoor device.

  Next, the air volume of the range hood 30 will be described. In the above range hood 30, when the user U uses the gas stove 20, there is an air volume suitable for the operating state of the gas stove 20. Therefore, the air volume of the range hood 30 corresponding to the operating state of the gas stove 20 is set in advance. Specifically, according to the fire extinguishing, “weak”, “medium”, and “strong” power of the gas stove 20, the air volume “0 (OFF)”, “weak”, “medium”, “Strong” is set.

  Further, in the above range hood 30, there is an air volume suitable for the air quality of the room 90 detected by the sensor 40. Therefore, the air volume of the range hood 30 corresponding to the air quality of the room 90 detected by the sensor 40 is set in advance. Specifically, corresponding to the air quality of “normal”, “slightly bad”, “bad”, “very bad” in the room 90, the air volume “0 (OFF)”, “weak”, “Medium” and “Strong” are set. Further, the air volume “strong” of the range hood 30 is set corresponding to the “unsafe” air quality in the room 90.

(First operation of the first embodiment)
Next, the operation of the ventilation system 1 will be described. First, the first operation of the first embodiment will be described. As shown in FIG. 2, in the initial state of the first embodiment, it is assumed that the gas stove 20 is not ignited and the heating power is “extinguishing”. Further, it is assumed that the air quality of the room 90 detected by the sensor 40 is “normal”. Further, it is assumed that the air volume of the range hood 30 is “0 (OFF)”.

  It is assumed that the user U of the gas stove 20 ignites the gas stove 20 by operating the operation unit 22 from this initial state. Further, it is assumed that the user U operates the operation unit 22 to set the fire power of the burner 21 to “weak”. Then, the gas stove 20 is ignited with the heating power “weak”. Further, the gas stove 20 transmits information on the thermal power “weak” to the range hood 30 (S11). The range hood 30 receives information on the thermal power “weak”.

  When the range hood 30 receives the information of the thermal power “weak” from the gas stove 20, the range hood 30 switches from OFF to ON and starts the ventilation operation. The range hood 30 ventilates the air in the room 90 by ventilation operation. At this time, the range hood 30 operates with an air volume “weak” corresponding to the heating power “weak” of the gas stove 20. The control unit 35 of the range hood 30 adjusts the air volume of the range hood 30 to “weak” based on the information on the heating power “weak” of the gas stove 20.

  In addition, when the range hood 30 operates with the air volume “weak” based on the information on the heating power “weak” of the gas stove 20, information for specifying that the range hood 30 is operating based on the information received from the gas stove 20 (operation factor specifying information) ) Is transmitted to the sensor 40 (S12). In FIG. 2, the operation factor specifying information is indicated as “gas stove”. The sensor 40 receives operating factor specifying information (gas stove). When the sensor 40 receives the operation factor specifying information (gas stove), the sensor 40 cannot transmit information related to the air quality in the room 90 to the range hood 30. Transmission of information related to the air quality of the room 90 from the sensor 40 to the range hood 30 is prohibited (S13).

  Thereafter, when the time has elapsed since the gas stove 20 ignited, the air quality in the room 90 changes from “normal” to “very bad”. For example, it is assumed that the air quality in the room 90 has changed to “very bad” due to smoke from the gas stove 20. The air quality in the room 90 is continuously detected by the sensor 40. The sensor 40 detects that the air quality in the room 90 has changed to “very bad”.

  When the air quality in the room 90 changes from “normal” to “very bad”, the sensor 40 detects the detected air quality “very bad” information when the operating factor specifying information (gas stove) is not received. However, when the operating factor specifying information (gas stove) is received, the detected air quality “very bad” information cannot be transmitted to the range hood 30 (S13). Transmission of the information on the air quality “very bad” detected by the sensor 40 to the range hood 30 is restricted. Since the range hood 30 does not receive the air quality “very bad” information from the sensor 40, the range hood 30 continues to operate with the air volume “weak” based on the information about the thermal power “weak” received from the gas stove 20.

(Second operation of the first embodiment)
Next, the second operation of the first embodiment will be described. As shown in FIG. 3, it is assumed that the initial state of the second operation of the first embodiment is the same as the first operation initial state of the first embodiment. That is, it is assumed that the gas stove 20 is not ignited and the thermal power is “fire extinguishing”. Further, it is assumed that the air quality of the room 90 detected by the sensor 40 is “normal”. Further, it is assumed that the air volume of the range hood 30 is “0 (OFF)”.

  It is assumed that the air quality in the room 90 has changed from “normal” to “somewhat bad” from this initial state. For example, it is assumed that the air quality in the room 90 changes to “slightly bad” due to smoke generated from the gas stove 20. The air quality in the room 90 is continuously detected by the sensor 40. The sensor 40 detects that the air quality in the room 90 has changed to “slightly bad”.

  When the air quality in the room 90 changes from “normal” to “somewhat bad”, the sensor 40 transmits information on the detected air quality “somewhat bad” to the range hood 30 (S41). The range hood 30 receives air quality “slightly bad” information.

  When the range hood 30 receives the air quality “slightly bad” information from the sensor 40, the range hood 30 switches from OFF to ON and starts the ventilation operation. The range hood 30 ventilates the air in the room 90 by ventilation operation. At this time, the range hood 30 operates with the air volume “weak” corresponding to the air quality “slightly bad” in the room 90. The control unit 35 of the range hood 30 adjusts the air volume of the range hood 30 to “weak” based on the air quality “slightly bad” information in the room 90.

  Thereafter, it is assumed that the user U of the gas stove 20 has ignited the gas stove 20 by operating the operation unit 22 when the air quality in the room 90 has changed to “slightly bad”. Further, it is assumed that the fire power of the burner 21 is set to “medium” by the user U operating the operation unit 22. Then, the gas stove 20 is ignited with the heating power “medium”. In addition, the gas stove 20 transmits information on the thermal power “medium” to the range hood 30 (S42). The range hood 30 receives information about the thermal power “medium”.

  When the range hood 30 receives the information of the heating power “middle” from the gas stove 20, the range hood 30 operates with the air volume “middle” corresponding to the heating power “middle”. The control unit 35 of the range hood 30 adjusts the air volume of the range hood 30 to “medium” based on the information of the heating power “medium” of the gas stove 20. The air volume of the range hood 30 switches from “weak” to “medium”. Thus, the information on the thermal power transmitted from the gas stove 20 to the range hood 30 is prioritized over the information on the air quality in the room 90 transmitted from the sensor 40 to the range hood 30.

  In addition, when the range hood 30 operates at the air volume “medium” based on the information on the heating power “medium” of the gas stove 20, information for identifying that the range hood 30 is operating based on the information received from the gas stove 20 (operation factor identification information) ) Is transmitted to the sensor 40 (S12). The sensor 40 receives operating factor specifying information (gas stove). When the sensor 40 receives the operation factor specifying information (gas stove), the sensor 40 cannot transmit information related to the air quality in the room 90 to the range hood 30. Transmission of information related to the air quality of the room 90 from the sensor 40 to the range hood 30 is prohibited (S13).

  The operation of the first embodiment has been described above. As is apparent from the above description, the ventilation system 1 includes the range hood 30 for ventilating the air in the room 90, the gas stove 20 disposed in the room 90, and the sensor 40. The range hood 30 is operable based on the information on the thermal power (an example of the first signal) transmitted from the gas stove 20 and the information on the air quality in the room 90 (an example of the second signal) transmitted from the sensor 40. When the range hood 30 receives information on the thermal power transmitted by the gas stove 20, the range hood 30 operates based on the information. Moreover, the range hood 30 can operate | move based on the information, when the information of the air quality of the room | chamber 90 which the sensor 40 transmits is received, when the information of the thermal power which the gas stove 20 transmits is not received.

  According to such a configuration, when the range hood 30 receives thermal power information from the gas stove 20, the range hood 30 operates based on the thermal power information, so the air volume of the range hood 30 does not change frequently. For example, in the first embodiment described above, when the range hood 30 is operating based on the information on the thermal power received from the gas stove 20, transmission of information related to the air quality of the room 90 from the sensor 40 to the range hood 30 is prohibited. (S13). That is, if the range hood 30 operates based on the information on the thermal power received from the gas stove 20, the range hood 30 cannot operate based on the information on the air quality in the room 90 detected by the sensor 40. On the other hand, when the range hood 30 has not received the information on the thermal power from the gas stove 20, when the information on the air quality in the room 90 is received from the sensor 40, the operation can be performed based on the information on the air quality. After that, when the range hood 30 receives information on the thermal power from the gas stove 20, it operates based on the information on the thermal power. Thus, since the operation based on the information on the thermal power received from the gas stove 20 is prioritized, it is possible to prevent the air volume of the range hood 30 from changing frequently.

  Further, in the ventilation system 1 described above, when the range hood 30 is operating based on the information on the thermal power transmitted from the gas stove 20, transmission of information on the air quality of the room 90 from the sensor 40 to the range hood 30 is prohibited. (S13). That is, communication between the range hood 30 and the sensor 40 is restricted.

  According to such a configuration, since the information related to the air quality in the room 90 is not transmitted from the sensor 40 to the range hood 30, it is possible to prevent the range hood 30 from operating erroneously based on the information related to the air quality.

  In the ventilation system 1 described above, the range hood 30 communicates with the gas stove 20 using an infrared communication method, and communicates with the sensor 40 using a Bluetooth communication method.

  According to such a configuration, it is possible to clearly distinguish the information on the thermal power received by the range hood 30 and the information on the air quality in the room 90 by distinguishing the communication methods.

  Moreover, in said ventilation system 1, the priority of the gas stove 20 is high and the priority of the sensor 40 is low. The gas stove 20 is disposed below the range hood 30. According to such a configuration, the surroundings of the gas stove 20 can be preferentially ventilated.

  Although one embodiment has been described above, the specific mode is not limited to the above embodiment. In the following description, the same components as those in the above description are denoted by the same reference numerals and the description thereof is omitted.

(Second embodiment)
In said 1st Example, when the range hood 30 is operate | moving based on the information of the thermal power which the gas stove 20 transmitted, it is prohibited that the sensor 40 transmits the information of the air quality of the room | chamber 90 to the range hood 30. However, the present invention is not limited to this configuration (see S13 above). In the second embodiment, as shown in FIG. 4, when the range hood 30 is operating based on the information on the thermal power transmitted from the gas stove 20, the range hood 30 obtains the air quality information of the room 90 from the sensor 40. The configuration may be such that reception is prohibited (S21). Even with such a configuration, communication between the range hood 30 and the sensor 40 is restricted as in the first embodiment. Since the range hood 30 does not receive the air quality “very bad” information from the sensor 40, the range hood 30 continues to operate at the air volume “weak” based on the information on the thermal power “weak” transmitted from the gas stove 20. In this case, the range hood 30 does not transmit the operation factor specifying information to the sensor 40 (see S12 in FIGS. 2 and 3).

(Third embodiment)
In the above embodiment, when the range hood 30 is operating based on the information on the thermal power transmitted from the gas stove 20, the communication between the range hood 30 and the sensor 40 is limited. In the embodiment, in a specific case, the restriction on communication between the range hood 30 and the sensor 40 may be released.

  As shown in FIG. 5, in the third embodiment, it is assumed that the air quality in the room 90 has changed to “unsafe” when the time has elapsed since the air quality in the room 90 has changed to “very bad”. . For example, it is assumed that combustion exhaust gas is generated from the gas stove 20 and the air quality in the room 90 has changed to “unsafe”. The state in which the air quality in the room 90 is “unsafe” is a state in which the air quality in the room 90 has deteriorated to such an extent that the physical condition of the user U in the room 90 becomes worse. The air quality in the room 90 is continuously detected by the sensor 40. The sensor 40 detects that the air quality in the room 90 has changed to “unsafe”.

  When the air quality in the room 90 changes from “very bad” to “unsafe”, the sensor 40 transmits the detected air quality “unsafe” information (an example of an unsafe signal) to the range hood 30 (S31). . The range hood 30 receives air quality “unsafe” information.

  When the information on the air quality “unsafe” is received from the sensor 40, the range hood 30 operates with the air volume “strong” corresponding to the air quality “unsafe”. The control unit 35 of the range hood 30 adjusts the air volume of the range hood 30 to “strong” based on the air quality “unsafe” information in the room 90. The air volume of the range hood 30 is switched from “weak” to “strong”. When the air quality in the room 90 is “unsafe”, the restriction on communication between the range hood 30 and the sensor 40 is released.

  As described above, in the ventilation system 1 according to the third embodiment, when the air quality in the room 90 detected by the sensor 40 is “unsafe” in light of a predetermined safety standard, this is specified. The sensor 40 transmits information “safe” to the range hood 30. When the range hood 30 receives the “unsafe” information transmitted from the sensor 40, the range hood 30 is based on the “unsafe” information even if it receives the thermal power information transmitted from the gas stove 20. Operate.

  According to such a configuration, when the air quality in the room 90 is “unsafe”, the “unsafe” information transmitted by the sensor 40 is prioritized, and the range hood 30 operates based on the information. . Thereby, the air quality in the room 90 can be maintained in a safe state.

(Fourth embodiment)
In the above embodiment, the range hood 30 directly receives the information on the thermal power transmitted by the gas stove 20, but is not limited to this configuration. In 4th Example, the structure which the range hood 30 receives indirectly the information of the thermal power which the gas stove 20 transmits may be sufficient. In 4th Example, the gas stove 20 and the sensor 40 are comprised so that communication is possible. The communication unit 23 of the gas stove 20 and the communication unit 43 of the sensor 40 perform wireless communication using, for example, an infrared communication method or a Bluetooth communication method.

  As shown in FIG. 6, it is assumed that the initial state of the fourth embodiment is the same as the initial state of the first embodiment. It is assumed that the user U of the gas stove 20 ignites the gas stove 20 by operating the operation unit 22 from this initial state. Further, it is assumed that the user U operates the operation unit 22 to set the fire power of the burner 21 to “weak”. Then, the gas stove 20 is ignited with the heating power “weak”. Further, the gas stove 20 transmits information on the thermal power “weak” to the sensor 40 (S111). The sensor 40 receives information on the thermal power “weak”. When the sensor 40 receives the information on the thermal power “weak”, the sensor 40 transmits the information to the range hood 30 (S112). The range hood 30 receives information on the fire power “weak”.

  When the range hood 30 receives the information of the thermal power “weak” from the gas stove 20, the range hood 30 switches from OFF to ON and starts the ventilation operation. The range hood 30 ventilates the air in the room 90 by ventilation operation. At this time, the range hood 30 operates with an air volume “weak” corresponding to the heating power “weak” of the gas stove 20. The control unit 35 of the range hood 30 adjusts the air volume of the range hood 30 to “weak” based on the information on the heating power “weak” of the gas stove 20.

  Thereafter, when the time has elapsed since the gas stove 20 ignited, the air quality in the room 90 changes from “normal” to “very bad”. For example, it is assumed that the air quality in the room 90 has changed to “very bad” due to smoke from the gas stove 20. The air quality in the room 90 is continuously detected by the sensor 40. The sensor 40 detects that the air quality in the room 90 has changed to “very bad”.

  When the air quality in the room 90 changes from “normal” to “very bad”, the sensor 40 compares the detected air quality “very bad” information with the information of the gas stove 20 “fire” and more ventilation. Information on the air quality “very bad” that requires the air volume is transmitted to the range hood 30 (S113). The range hood 30 receives air quality “very bad” information.

  When the range hood 30 receives the information on the air quality “very bad” from the sensor 40, the range hood 30 operates with the air volume “strong” corresponding to the air quality “very bad”. The control unit 35 of the range hood 30 adjusts the air volume of the range hood 30 to “strong” based on the information of the air quality “very bad” in the room 90. The air volume of the range hood 30 is switched from “weak” to “strong”.

  As described above, the range hood 30 relays the sensor 40 and indirectly receives information on the thermal power transmitted from the gas stove 20. On the other hand, regarding the information transmitted by the sensor 40, the range hood 30 directly receives from the sensor 40 without relaying the gas stove 20. Therefore, the range hood 30 can directly receive the information regarding the air quality of the room 90 transmitted by the sensor 40 from the sensor 40 without relaying the gas stove 20.

(5th Example)
In the above embodiment, the gas stove 20 and the sensor 40 are configured to be communicable, but the gas stove 20 and the sensor 40 may be unable to communicate due to radio wave interference, for example. In the normal state, the gas stove 20 and the sensor 40 can communicate, and in the non-normal state, the gas stove 20 and the sensor 40 cannot communicate. That is, communication between the gas stove 20 and the sensor 40 is restricted in an abnormal state.

  In the fifth embodiment, in a normal state (a state where the gas stove 20 and the sensor 40 can communicate), as shown in FIG. 6, the gas stove 20 transmits information on the thermal power “weak” to the sensor 40 (S111). Further, when the sensor 40 receives information on the thermal power “weak”, the information is transmitted to the range hood 30 (S112). The range hood 30 relays the sensor 40 and indirectly receives information on the thermal power transmitted from the gas stove 20.

  On the other hand, in a non-normal state (a state where the gas stove 20 and the sensor 40 cannot communicate), as shown in FIG. 2, the gas stove 20 transmits information on the thermal power “weak” to the range hood 30 (S11). The range hood 30 receives the information of the thermal power transmitted from the gas stove 20 directly from the gas stove 20 without relaying the sensor 40. The control unit (not shown) of the gas stove 20 can determine whether the normal state or the non-normal state.

  In addition, about the information which the sensor 40 transmits, the range hood 30 receives directly from the sensor 40, without relaying the gas stove 20, even if it is a normal state or a non-normal state. Therefore, the range hood 30 can directly receive the information regarding the air quality of the room 90 transmitted by the sensor 40 from the sensor 40 without relaying the gas stove 20 (see S41 in FIG. 3 and S113 in FIG. 6). ).

(Sixth embodiment)
In the above embodiment, the range hood 30 directly receives the air quality information of the room 90 transmitted by the sensor 40, but the present invention is not limited to this configuration. In 6th Example, the structure which the range hood 30 receives indirectly the information of the air quality of the room | chamber 90 which the sensor 40 transmits may be sufficient. In 6th Example, the gas stove 20 and the sensor 40 are comprised so that communication is possible. The communication unit 23 of the gas stove 20 and the communication unit 43 of the sensor 40 perform wireless communication using, for example, an infrared communication method or a Bluetooth communication method.

  As shown in FIG. 7, it is assumed that the initial state of the sixth embodiment is the same as the initial state of the first embodiment. It is assumed that the air quality in the room 90 has changed from “normal” to “somewhat bad” from this initial state. For example, it is assumed that the air quality in the room 90 changes to “slightly bad” due to smoke generated from the gas stove 20. The air quality in the room 90 is continuously detected by the sensor 40. The sensor 40 detects that the air quality in the room 90 has changed to “slightly bad”.

  When the air quality in the room 90 changes from “normal” to “somewhat bad”, the sensor 40 transmits information on the detected air quality “somewhat bad” to the gas stove 20 (S411). The gas stove 20 receives the air quality “slightly bad” information. When the gas stove 20 receives the air quality “slightly bad” information, the gas stove 20 transmits the information to the range hood 30 (S412). The range hood 30 receives the air quality “slightly bad” information.

  When the range hood 30 receives the air quality “slightly bad” information from the gas stove 20, the range hood 30 switches from OFF to ON and starts the ventilation operation. The range hood 30 ventilates the air in the room 90 by ventilation operation. At this time, the range hood 30 operates with the air volume “weak” corresponding to the air quality “slightly bad” in the room 90. The control unit 35 of the range hood 30 adjusts the air volume of the range hood 30 to “weak” based on the air quality “slightly bad” information in the room 90.

  Thereafter, it is assumed that the user U of the gas stove 20 has ignited the gas stove 20 by operating the operation unit 22 when the air quality in the room 90 has changed to “slightly bad”. Further, it is assumed that the fire power of the burner 21 is set to “medium” by the user U operating the operation unit 22. Then, the gas stove 20 is ignited with the heating power “medium”. Further, the gas stove 20 compares the information on the air quality “slightly bad” with the information on the thermal power “medium”, and transmits the information on the thermal power “medium” that requires a larger ventilation air volume to the range hood 30 (S413). ). The range hood 30 receives information about the thermal power “medium”.

  When the range hood 30 receives the information of the heating power “middle” from the gas stove 20, the range hood 30 operates with the air volume “middle” corresponding to the heating power “middle”. The control unit 35 of the range hood 30 adjusts the air volume of the range hood 30 to “medium” based on the information of the heating power “medium” of the gas stove 20. The air volume of the range hood 30 switches from “weak” to “medium”.

(Seventh embodiment)
In the above embodiment, the gas stove 20 and the sensor 40 are configured to be communicable, but the gas stove 20 and the sensor 40 may be unable to communicate due to radio wave interference, for example. In the normal state, the gas stove 20 and the sensor 40 can communicate, and in the non-normal state, the gas stove 20 and the sensor 40 cannot communicate. That is, communication between the gas stove 20 and the sensor 40 is restricted in an abnormal state.

  In the seventh embodiment, in a normal state (a state where the gas stove 20 and the sensor 40 can communicate), as shown in FIG. 7, the sensor 40 transmits air quality information in the room 90 to the gas stove 20 (S411). Further, when the gas stove 20 receives the air quality information of the room 90, the information is transmitted to the range hood 30 (S412). The range hood 30 receives the air quality information in the room 90 transmitted by the sensor 40 indirectly via the gas stove 20.

  On the other hand, in a non-normal state (a state where the gas stove 20 and the sensor 40 cannot communicate), as shown in FIG. 3, the sensor 40 transmits air quality information of the room 90 to the range hood 30 (S41). The range hood 30 directly receives the air quality information of the room 90 transmitted by the sensor 40 from the sensor 40 without relaying the gas stove 20. A control unit (not shown) of the sensor 40 can determine whether the normal state or the non-normal state.

  In addition, about the information which the gas stove 20 transmits, the range hood 30 receives directly from the gas stove 20 without relaying the sensor 40, even if it is a normal state or a non-normal state. Therefore, the range hood 30 can directly receive information on the thermal power transmitted from the gas stove 20 from the gas stove 20 without relaying the sensor 40 (see S42 in FIG. 3 and S413 in FIG. 7).

  The operation of the fourth to seventh embodiments has been described above. As apparent from the above description, in the ventilation system 1 described above, the gas stove 20 and the sensor 40 can communicate with each other. In addition, the range hood 30 can receive information on the thermal power from the gas stove 20 in a normal state, while receiving information on the air quality in the room 90 via the gas stove 20. Alternatively, the range hood 30 can receive information on the air quality in the room 90 from the sensor 40 in a normal state, while receiving information on the thermal power via the sensor 40. In a normal state, the range hood 30 is operable based on information received from a device that relays information regardless of the order of reception of thermal power information and air quality information. The range hood 30 can receive thermal power information from the gas stove 20 without relaying the sensor 40 in the non-normal state where communication between the gas stove 20 and the sensor 40 is restricted, and can receive air quality information in the room 90. The gas stove 20 can be received from the sensor 40 without being relayed. In the non-normal state, the range hood 30 operates based on the information on the thermal power when the information on the thermal power transmitted by the gas stove 20 is received. Further, in the non-normal state, the range hood 30 is based on the air quality information when the air quality information transmitted by the sensor 40 is received when the thermal power information transmitted by the gas stove 20 is not received. Operate.

  According to such a configuration, it is possible to unify the channels through which the range hood 30 receives information by unifying the apparatus in which the range hood 30 normally receives information into the gas stove 20 or the sensor 40. Further, for example, even if the gas stove 20 and the sensor 40 become incapable of communication due to radio interference or the like and become non-normal, if the air cooker operates based on the thermal power information received from the gas stove 20, the air quality of the room 90 detected by the sensor 40 is detected. Can not work based on information about. On the other hand, when the range hood 30 has not received the information on the thermal power from the gas stove 20, when the information on the air quality in the room 90 is received from the sensor 40, the operation can be performed based on the information on the air quality. After that, when the range hood 30 receives information on the thermal power from the gas stove 20, it operates based on the information on the thermal power. Thus, since the operation based on the information on the thermal power received from the gas stove 20 is given priority, the operation can be performed so that the air volume of the range hood 30 does not change frequently.

(Other examples)
In the above-described embodiment, when the range hood 30 is operating based on the information on the thermal power received from the gas stove 20, the communication between the range hood 30 and the sensor 40 is restricted in an abnormal state. However, the configuration is not limited to this configuration, and may be a configuration in which communication between the range hood 30 and the sensor 40 is not limited. However, when the range hood 30 is operating based on the information on the thermal power transmitted by the gas stove 20, even if the information on the air quality in the room 90 transmitted by the sensor 40 is received in an abnormal state, the information is included in the information. Does not operate based on (continues to operate based on information received from gas stove 20). When the range hood 30 receives the air quality information of the room 90 transmitted by the sensor 40, the range hood 30 operates based on the information received from the sensor 40 only when the information of the thermal power transmitted by the gas stove 20 is not received. To do.

  In the above embodiment, the gas stove 20 has been described as an example of the first indoor device. However, the present invention is not limited to this. Moreover, although the sensor 40 was demonstrated as an example of a 2nd indoor device, it is not limited to this. The combination of the first indoor device and the second indoor device is a combination of arbitrary devices arranged in the room 90.

  In the above embodiment, the communication unit 33 of the range hood 30 and the communication unit 23 of the gas stove 20 communicate wirelessly by an infrared communication method, and the communication unit 33 of the range hood 30 and the communication unit 43 of the sensor 40 are Bluetooth communication methods. However, the communication method is not particularly limited.

  In another embodiment, the control unit 35 of the range hood 30 may recognize the priority of the indoor devices (the gas stove 20 and the sensor 40) and the priority of the communication method, and determine according to the priority. Good.

  In addition, by changing the setting of the indoor device that the user U wants to temporarily prioritize, the indoor device temporarily transmits a high priority signal (an example of a third signal), and the range hood 30 temporarily You may operate | move based on a high priority signal.

  For example, it is assumed that the user U temporarily wants to operate the range hood 30 with an air volume corresponding to the air quality of the room 90 detected by the sensor 40. In this case, the user U inputs it to the sensor 40. That is, the user U inputs to the sensor 40 that the sensor 40 is temporarily given priority over the gas stove 20. For example, priority information is input to the sensor 40 by a remote controller or the like. In this case, the sensor 40 transmits priority information (high priority signal) to the range hood 30. The range hood 30 receives priority information. When the range hood 30 receives the priority information transmitted from the sensor 40, the range hood 30 detects the indoor 90 detected by the sensor 40 based on the priority information even if it receives the thermal power information transmitted from the gas stove 20. It operates with air volume according to the air quality. Such an operation is performed when the gas stove 20 and the sensor 40 cannot communicate. When the gas stove 20 and the sensor 40 cannot communicate with each other, for example, when the gas stove 20 and the sensor 40 cannot communicate with each other, or the gas stove 20 and the sensor 40 can communicate with each other, the gas stove 20 as in the above-described non-normal state. And the communication between the sensor 40 and the sensor 40 is restricted.

  As described above, when the gas stove 20 and the sensor 40 cannot communicate with each other, the sensor 40 receives priority information when a predetermined condition is satisfied (for example, when the user U inputs priority information to the sensor 40 with a remote controller or the like). May be sent. Moreover, the range hood 30 may operate | move based on priority information, even when it is the case where the information of the thermal power which the gas stove 20 transmits is received when the priority information which the sensor 40 transmits is received.

  According to such a configuration, it is possible to cause the range hood 30 to execute the ventilation operation reflecting the intention of the user U.
