[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the description of the drawings, the same elements are given the same reference numerals, and duplicated description will be omitted. Also, the dimensional ratios of the drawings are exaggerated for the convenience of explanation, and may differ from the actual ratios. In the following description, the up and down in the direction of gravity will be simply referred to as up and down.

[0011] <Embodiment> [Configuration of ventilation system 1] FIG. 1 shows an example of a schematic configuration of a ventilation system 1 according to an embodiment. The ventilation system 1 includes a ventilation device 100 and a cooking device 200. The ventilation device 100 and the cooking device 200 are configured to be able to communicate with each other, for example, by wire or wirelessly. The ventilation device 100 and the cooking device 200 are each configured to be able to connect to an external electronic device 300 via a network, for example. The ventilation system 1 is installed, for example, in a kitchen of a residence. A person to be watched lives in the residence. The electronic device 300 is owned by a person watching over the person. The person and the person watching over may be the same person. The ventilation system 1 ventilates the kitchen and detects any abnormality in the living situation of the person. Here, the ventilation device 100 corresponds to a specific example of a kitchen device of the present invention.

[0012] 2 and 3 show an example of the configuration of the ventilation device 100 and the cooking device 200 installed in a kitchen. FIG. 2 is a front view of the ventilation device 100 and the cooking device 200, and FIG. 3 is a right-side cross-sectional view of the ventilation device 100 and the cooking device 200. The ventilation device 100 is installed on top of the cooking device 200. When a subject uses the cooking device 200, odors, smoke, oily smoke, etc. are generated. The ventilation device 100 plays a role of sucking in the odors, smoke, oily smoke, etc. and discharging them to the outside. The outside is, for example, the outside of a residence in which a kitchen is installed, that is, outdoors. The cooking device 200 is used for cooking by the subject.

[0013] The ventilation device 100 includes, for example, a blower box 110, an operation receiving unit 120, a control unit 130, a display unit 140, a lighting unit 150, an audio output unit 160, a communication unit 170, an oil pack 180, and a sensor 190. Here, the blower box 110 corresponds to a specific example of a ventilation unit of the present invention. The ventilation device 100 is, for example, a range hood. The ventilation device 100 may also be a ventilation fan.

[0014] The blower box 110 exhausts odors, oily smoke, and the like generated by the cooking device 200. The blower box 110 is provided with, for example, an intake port 112, an exhaust port 114, a fan 116, a fan motor 117, a filter 118, and a filter motor 119. The intake port 112 is a portion that sucks in oily smoke generated by the cooking device 200. The exhaust port 114 is a portion that communicates with the outdoors. The fan 116 is provided in a passage that connects the intake port 112 and the exhaust port 114. The fan 116 is driven by the fan motor 117. The filter 118 is provided, for example, between the intake port 112 and the fan 116. The filter 118 removes oil from the oily smoke sucked from the intake port 112 by, for example, rotating. The filter 118 is driven by the filter motor 119. For example, when the fan 116 rotates, the filter 118 also rotates. The filter 118 may be non-rotating and may remove oil. The blower box 110 may not have a filter.

[0015] The operation receiving unit 120 and the display unit 140 are provided, for example, on the front side of the ventilation device 100. The operation receiving unit 120 receives, for example, an instruction from a subject regarding the operation of the ventilation device 100. The instruction received by the operation receiving unit 120 is transmitted, for example, to the control unit 130.

[0016] 4 shows an example of the configuration of the operation reception unit 120. The operation reception unit 120 includes an operation switch 121, a mode changeover switch 122, a timer switch 123, a constant ventilation switch 124, and a lighting switch 125.

[0017] The operation switch 121 is a switch for operating the ventilation device 100. When the subject presses the operation switch 121, an operation start signal is transmitted to the control unit 130. When the subject presses the operation switch 121 while the ventilation device 100 is operating, an operation end signal is transmitted to the control unit 130.

[0018] It is preferable that the ventilation device 100 is configured to be controllable based on instruction information transmitted from the electronic device 300. This allows the watcher to, for example, turn the ventilation device 100 on / off and adjust the air volume even when the watcher is in a location away from the ventilation device 100.

[0019] The mode changeover switch 122 is a switch for changing the air volume of the fan 116 and / or the rotation speed of the filter 118. By using the mode changeover switch 122, the subject can change the strength between three levels, for example, weak, medium, and strong. When the mode changeover switch 122 is set to weak, the fan 116 operates at the minimum air volume set, and / or the filter 118 operates at the minimum rotation speed set. When the mode changeover switch 122 is set to medium, the fan 116 operates at a larger air volume than weak, and / or the filter 118 operates at a faster rotation speed than weak. When the mode changeover switch 122 is set to strong, the fan 116 operates at a larger air volume than medium, and / or the filter 118 operates at a faster rotation speed than medium. The subject can, for example, manually change the air volume of the fan 116 and / or the rotation speed of the filter 118. The ventilation device 100 may detect the temperature above the cooking appliance 200, and may switch the air volume of the fan 116 and / or the rotation speed of the filter 118 according to the detected temperature.

[0020] The timer switch 123 is a switch for performing timer operation, which rotates the fan 116 and / or the filter 118 for a set time after cooking is completed. When the subject presses the timer switch 123, a normal operation end signal is sent to the control unit 130, and the ventilator 100 performs timer operation for a predetermined time.

[0021] The constant ventilation switch 124 is a switch for starting / stopping the constant ventilation by rotating / stopping the fan 116 and / or the filter 118.

[0022] The lighting switch 125 is a switch for turning the lighting unit 150 on and off.

[0023] The control unit 130 controls the operation of the ventilator 100. The control unit 130 is configured, for example, with a central processing unit (CPU) and memories such as a random access memory (RAM) and a read only memory (ROM). The control unit 130 controls each part of the ventilator 100 and performs calculation processing according to a program, for example. The control unit 130 may further include a hard disk drive (HDD) as a memory. Specific functions of the control unit 130 will be described later.

[0024] The display unit 140 is configured with, for example, a liquid crystal display or the like. The subject can visually confirm the information displayed on the display unit 140. The illumination unit 150 includes, for example, an LED (Light Emitting Diode) or the like. The illumination unit 150 is disposed at a position where it illuminates the cooking device 200.

[0025] The audio output unit 160 is configured by, for example, a speaker etc. The subject can confirm the information output from the audio output unit 160 by hearing it.

[0026] The communication unit 170 has a communication function. The ventilation device 100 has the communication unit 170, which enables transmission and reception of signals with the cooking appliance 200 and the electronic device 300. The communication unit 170 has a function of performing wireless communication according to a standard such as Wi-Fi or Bluetooth (registered trademark). The communication unit 170 communicates with the cooking appliance 200 and the electronic device 300 directly or via an access point. The ventilation device 100 may be connected to an external sensor via the communication unit 170.

[0027] Oil pack 180 is a member that receives oil accumulated in blower box 110. For example, an oil reservoir (not shown) is provided in blower box 110, and oil pack 180 is disposed below this oil reservoir.

[0028] The sensor 190 includes, for example, a human sensor, a temperature sensor, a gas sensor, an odor sensor, a light sensor, etc. Information detected by the sensor 190 is transmitted to the control unit 130, for example.

[0029] The human presence sensor detects the presence or absence of a person around the ventilation device 100. For example, when a subject is cooking using the cooking appliance 200, the human presence sensor detects the presence of a person. The human presence sensor is, for example, a pyroelectric infrared sensor, an ultrasonic sensor, a microwave sensor, a distance sensor, or the like. The control unit 130 can estimate the presence or absence of a person around the ventilation device 100 and the presence or absence of human movement based on, for example, information detected by the human presence sensor. For example, the lighting unit 150 may include a human presence sensor.

[0030] The temperature sensor includes, for example, an infrared sensor such as a single-eye temperature sensor or a multi-eye temperature sensor, and detects the temperature above the cooking appliance 200. The control unit 130 can estimate the usage state of the cooking appliance 200 based on, for example, information detected by the temperature sensor. Here, this temperature sensor corresponds to a specific example of a first detection unit of the present invention.

[0031] The gas sensor detects, for example, a predetermined gas contained in the air surrounding the ventilation device 100. The gas sensor detects, for example, a combustible gas, carbon monoxide (CO), and carbon dioxide (CO 2 The control unit 130 can estimate the concentration of a predetermined gas contained in the air around the ventilation device 100, for example, based on information detected by the gas sensor.

[0032] The odor sensor detects odors around the ventilation device 100. For example, the odor sensor can detect odors generated from food being cooked by the cooking appliance 200. The odor sensor may detect odors throughout the entire residence. The odor sensor is provided, for example, in a passage connecting the air intake 112 and the exhaust 114. The odor sensor may be provided in a duct portion that connects the exhaust 114 to the outdoors. The control unit 130 can estimate odor components around the ventilation device 100, for example, based on information detected by the odor sensor. Here, this odor sensor corresponds to a specific example of a second detection unit of the present invention.

[0033] The light sensor detects light around the ventilation device 100. The control unit 130 can estimate whether the lights in the kitchen or in the rooms around the kitchen are on or not, based on the information detected by the light sensor.

[0034] Cooking device 200 has, for example, heat source 210, grill 220, control unit 230, operation reception unit 240, communication unit 250, cooking utensils 260, and sensor 270. Heat source 210 is, for example, a burner for a gas cooker or a trivet near the burner. Heat source 210 may be a heater for an IH (Induction Heating) cooker, or the like. Cooking device 200 has, for example, three heat sources 210. Cooking utensils 260 are, for example, a pot, a frying pan, or the like.

[0035] Cooking appliance 200 is preferably configured to be controllable based on instruction information transmitted from electronic device 300. This allows the watcher to, for example, turn on cooking appliance 200, turn off the fire, adjust the heat, set the child lock, and so on, even when the watcher is in a location away from cooking appliance 200.

[0036] 5 is a block diagram showing an example of the relationship between the control unit 230 and each part of the cooking device 200. The control unit 230 has a CPU, RAM, ROM, etc., similar to the control unit 130 of the ventilation device 100, and controls and performs calculation processing on each part of the cooking device 200. The operation reception unit 240 receives, for example, instructions from a subject regarding the operation of the cooking device 200. The instructions received by the operation reception unit 240 are transmitted, for example, to the control unit 230. The communication unit 250, similar to the communication unit 170 of the ventilation device 100, is capable of wireless communication using standards such as Wi-Fi and Bluetooth, and communicates with each device via an access point or directly.

[0037] Sensor 270 detects the state of each part of cooking device 200. Sensor 270 includes, for example, a heating temperature sensor that detects the temperature of heat source 210 and the temperature of grill 220. The heating temperature sensor may detect the temperature of the bottom of cooking utensil 260 provided on heat source 210. Sensor 270 transmits the detected information to control unit 230.

[0038] 6 is a block diagram showing an example of a schematic configuration of electronic device 300. Electronic device 300 is, for example, a smartphone, a tablet terminal, or a mobile phone carried by a watcher. Electronic device 300 may be a PC (Personal Computer). Electronic device 300 has, for example, a control unit 310, a communication unit 320, a display unit 330, an operation reception unit 340, and a voice input / output unit 350.

[0039] The control unit 310, like the control unit 130 of the ventilation device 100, has a CPU, RAM, ROM, etc., and controls each unit of the electronic device 300 and performs arithmetic processing.

[0040] The communication unit 320, like the communication unit 170 of the ventilator 100, is capable of wireless communication using standards such as Wi-Fi and Bluetooth, and communicates with each device directly or via an access point.

[0041] The display unit 330 and the operation receiving unit 340 are, for example, a touch panel display, which displays various information provided by the ventilation device 100 and receives input of instructions from the watcher for the ventilation device 100. The audio input / output unit 350 includes, for example, a microphone that converts sound into an electrical signal, and a speaker that converts the electrical signal into sound and outputs it as air vibrations.

[0042] [Functions of the control unit 130] 7 is a block diagram showing an example of the functions of the control unit 130. For example, in the control unit 130, the CPU reads out various programs stored in advance in the ROM into the RAM and executes them, thereby functioning as an acquisition unit 131, a determination unit 132, and an output unit 133.

[0043] The acquisition unit 131 acquires surrounding information related to the state of the surroundings of the ventilation device 100. The surrounding information includes, for example, device information related to the usage state of devices provided around the ventilation device 100. The devices include, for example, the cooking appliance 200.

[0044] The usage state of cooking appliance 200 is detected, for example, by a temperature sensor included in sensor 190. The temperature sensor detects the temperature in the vicinity of cooking appliance 200, and control unit 130 estimates the usage state of cooking appliance 200 based on information detected by this temperature sensor. For example, when the temperature above heat source 210 detected by the temperature sensor exceeds a predetermined temperature, control unit 130 estimates that heat source 210 has been ignited. For example, when the temperature above heat source 210 detected by the temperature sensor exceeds a predetermined temperature and then drops rapidly, control unit 130 estimates that heat source 210 has been extinguished.

[0045] The sensor 190 of the ventilation device 100 detects the usage state of the cooking appliance 200, so that the usage state of the cooking appliance 200 can be accurately detected even when a problem occurs in the communication state between the ventilation device 100 and the cooking appliance 200. In addition, the usage state of a cooking appliance not connected to the ventilation device 100 can also be accurately detected.

[0046] The usage state of the cooking appliance 200 may be estimated based on information from the control unit 230 of the cooking appliance 200. For example, the operation reception unit 240 of the cooking appliance 200 receives an instruction to turn on or off the heat source 210 from the subject person, and transmits the instruction to the control unit 230. The control unit 230 transmits the information received from the operation reception unit 240 to the control unit 130 via the communication unit 250. At this time, the control unit 130 estimates whether the heat source 210 has been turned on or off. The usage state of the cooking appliance 200 may be detected by, for example, a heating temperature sensor included in the sensor 270.

[0047] The device information may include information regarding the usage state of each of a plurality of devices provided around the ventilation device 100. The devices may be a refrigerator, a microwave oven, a rice cooker, a water supply, and the like.

[0048] The surrounding information includes, for example, human information related to the state of people around the ventilation device 100. For example, a human sensor included in the sensor 190 detects the movement of people around the ventilation device 100, and the control unit 130 estimates whether or not people are moving around the ventilation device 100 based on the detection information of the human sensor.

[0049] The surrounding information includes, for example, gas information related to the state of gas around the ventilation device 100. For example, a gas sensor included in the sensor 190 detects a predetermined gas around the ventilation device 100, and the control unit 130 estimates the concentration of the predetermined gas around the ventilation device 100 based on the information detected by the gas sensor. The gas information includes, for example, information related to the concentration of each of a plurality of types of gas.

[0050] The surrounding information includes, for example, odor information related to the state of odors around the ventilation device 100. For example, an odor sensor included in the sensor 190 detects odors around the ventilation device 100, and the control unit 130 estimates the components of the odors around the ventilation device 100 based on the information detected by the odor sensor. The ventilation device 100 has a relatively high ventilation performance within the residence. Therefore, the odor sensor installed in the passage connecting the intake port 112 and the exhaust port 114 can detect odors not only in the kitchen but throughout the residence.

[0051] The surrounding information includes, for example, light information related to the light conditions around the ventilation device 100. For example, a light sensor included in the sensor 190 detects the light around the ventilation device 100, and the control unit 130 estimates the brightness around the ventilation device 100 based on the information detected by the light sensor.

[0052] The acquisition unit 131 acquires surrounding information including at least one of, for example, device information, human information, gas information, odor information, and light information. The acquisition unit 131 may acquire the surrounding information continuously or intermittently. The acquisition unit 131 may acquire the surrounding information periodically or irregularly. The acquisition unit 131 may acquire the surrounding information when it receives an instruction from the watcher via the operation reception unit 340 of the electronic device 300, for example.

[0053] The determination unit 132 determines whether or not there is an abnormality in the living situation of the subject based on the surrounding information acquired by the acquisition unit 131. For example, the determination unit 132 determines whether or not there is an abnormality based on the device information included in the surrounding information. Specifically, when the cooking appliance 200 has not been used for a predetermined time, the determination unit 132 determines that there is an abnormality. When the cooking appliance 200 has not been used for a long time, it is suspected that the subject is not normally active in the residence. Therefore, it is possible to detect an abnormality in the living situation of the subject caused by poor health or the like.

[0054] The determination unit 132 determines whether or not there is an abnormality based on, for example, human information included in the surrounding information. Specifically, when there is no human movement around the ventilation device 100 for a predetermined time, the determination unit 132 determines that there is an abnormality. When there is no human movement around the ventilation device 100 for a long period of time, it is suspected that the subject is not acting normally in the residence. Therefore, it is possible to detect an abnormality in the living situation of the subject caused by poor physical condition, etc.

[0055] The determination unit 132 determines whether or not there is an abnormality based on, for example, gas information included in the surrounding information. Specifically, when the concentration of a predetermined gas around the ventilation device 100 exceeds a predetermined concentration, the determination unit 132 determines that there is an abnormality. The predetermined gas is, for example, a combustible gas, carbon monoxide, or carbon dioxide. When the concentration of the combustible gas around the ventilation device 100 is relatively high, incomplete combustion of the cooking device 200 or insufficient ventilation of the ventilation device 100 is suspected. Therefore, it is possible to detect an abnormality in the living conditions of the subject caused by a deterioration in the air environment in the residence.

[0056] The determination unit 132 determines whether or not there is an abnormality based on, for example, odor information included in the ambient information. Specifically, when the change in odor around the ventilation device 100 within a predetermined time period is within a predetermined range, the determination unit 132 determines that there is an abnormality. Since various odors are generated when humans live, the odor around the ventilation device 100 also changes when the subject is acting normally. For this reason, when the odor around the ventilation device 100 remains almost unchanged for a long period of time, it is suspected that the subject is not acting normally in the residence. Therefore, it is possible to detect abnormalities in the subject's living conditions due to poor physical condition, etc.

[0057] When a specific odor is contained in the odor around the ventilation device 100, the determination unit 132 may determine that there is an abnormality. The specific odor is, for example, the odor of death or decay. This makes it possible to detect an abnormality when something happens to a subject or his / her residence.

[0058] The determination unit 132 determines whether or not there is an abnormality based on, for example, light information included in the surrounding information. Specifically, when the brightness around the ventilation device 100 is equal to or lower than a predetermined brightness for a predetermined time, the determination unit 132 determines that there is an abnormality. When the lights around the ventilation device 100 are not turned on for a long period of time, including at night, it is suspected that the subject is not acting normally in the residence. Therefore, it is possible to detect an abnormality in the living situation of the subject caused by poor physical condition, etc.

[0059] When the determination unit 132 determines that an abnormality has occurred, the output unit 133 outputs abnormality information regarding this abnormality. The output unit 133 outputs the abnormality information, for example, by transmitting the abnormality information to the electronic device 300. The electronic device 300 displays the abnormality information received from the ventilation device 100, for example, on the display unit 330. This allows the watcher to notice that an abnormality has occurred in the living situation of the subject, even if he or she is in a place away from the subject's residence.

[0060] For example, a screen informing that the cooking appliance 200 has not been used for a long period of time is displayed on the display unit 330. This makes it possible for the watcher to notice that the subject is in poor health or that the subject is not at home.

[0061] The display unit 330 displays, for example, a screen informing that there has been no human movement around the ventilation device 100 for a long period of time. This makes it possible for the watcher to notice that the subject is in poor physical condition or that the subject is not at home.

[0062] For example, a screen is displayed on the display unit 330 to inform the user that the concentration of combustible gas around the ventilation device 100 is increasing. This makes it possible for the watcher to notice that the air environment in the subject's residence is deteriorating.

[0063] For example, a screen is displayed on the display unit 330 to inform the user that the odor around the ventilation device 100 has not changed for a long period of time. This makes it possible for the watcher to notice the subject's poor physical condition or the subject's absence from the residence.

[0064] For example, a screen is displayed on the display unit 330 to inform the user that the lights around the ventilation device 100 have not been turned on for a long period of time. This makes it possible for the person watching over the subject to notice that the subject is not in good health or that the subject is not at home.

[0065] 8 shows an example of the relationship between the ventilation system 1 and electronic devices (electronic devices 301, 302, 303). The output unit 133 may be configured to output abnormality information to each of the multiple electronic devices (electronic devices 301, 302, 303). This makes it possible to notify multiple watchers of an abnormality in the living situation of the subject. This makes it easier for the watchers to notice the abnormality.

[0066] The output unit 133 may output the abnormality information by causing the display unit 140 of the ventilator 100 to display a screen similar to that of the display unit 330 described above.

[0067] The output unit 133 may output the abnormality information by causing at least one of the audio output unit 160 and the audio input / output unit 350 to output a sound indicating that an abnormality has occurred in the living situation of the subject. When the determination unit 132 determines that there is no abnormality in the living situation of the subject, the output unit 133 may output normal information different from the abnormality information.

[0068] FIG. 9 is a flowchart showing the procedure of the process executed by the control unit 130.

[0069] First, the control unit 130 acquires surrounding information related to the surrounding conditions of the ventilation device 100 (step S101). Next, the control unit 130 determines whether or not there is an abnormality in the living situation of the subject based on the surrounding information acquired in step S101 (step S102).

[0070] When it is determined that no abnormality has occurred (step S102: NO), the control unit 130 repeats the processes of steps S101 and S102.

[0071] When it is determined that an abnormality has occurred (step S102: YES), the control unit 130 outputs abnormality information regarding the abnormality (step S103) and ends the process. The control unit 130 outputs the abnormality information, for example, by transmitting the abnormality information to the electronic device 300. The electronic device 300 that has received the abnormality information from the ventilation device 100 causes the display unit 330 to display a predetermined screen, for example.

[0072] [Functions and Effects of the Ventilation Device 100 and the Ventilation System 1] In the ventilation device 100 of the ventilation system 1 of this embodiment, the control unit 130 acquires surrounding information on the state of the surroundings of the ventilation device 100, and judges whether or not there is an abnormality in the living situation of the subject based on the surrounding information. Therefore, it becomes possible to detect an abnormality in the living situation of the person being watched. The effect of this will be described in detail below.

[0073] In the case of elderly people living alone, even if the resident becomes unwell, it is difficult for family members and relatives to notice the abnormality. For this reason, there is a need for the development of a technology that can notify the abnormality of the person being watched. For example, a method in which a device installed in the house detects the abnormality of the subject's living situation based on information about the status of the device itself is conceivable. However, with this method, the abnormality of the subject's living situation is detected only from information about the status of one device, so there is a risk that the abnormality will not be detected with sufficient accuracy.

[0074] In contrast, the ventilation device 100 of the ventilation system 1 judges whether there is an abnormality in the living situation of the subject based on surrounding information related to the conditions around the ventilation device 100. Therefore, it is possible to detect an abnormality in the living situation of the subject from various information over a wide range around the device. Therefore, it is possible to detect an abnormality in the living situation of the person being watched with higher accuracy. This makes it easier for the person watching over to notice an abnormality in the living situation of the subject, and to take necessary measures early.

[0075] As described above, in the ventilation device 100 and the ventilation system 1 of the present embodiment, the presence or absence of an abnormality in the living situation of the subject is determined based on the surrounding information related to the state around the ventilation device 100. Therefore, it becomes possible to detect an abnormality in the living situation of the person being watched over with high accuracy.

[0076] The following describes modified examples of the ventilation system 1 described in the above embodiment. In the following, in order to avoid duplication of explanation, detailed explanations of configurations similar to those of the ventilation system 1 described in the above embodiment will be omitted.

[0077] <Modification> 10 shows a schematic configuration of a ventilation system 1 according to a modified example. This ventilation system 1 has ventilation devices 100A, 100B, cooking appliances 200A, 200B, and a transmission device 400. Except for this point, the ventilation system 1 described in the modified example has a similar configuration to the ventilation system 1 described in the above embodiment, and exerts the same effects. Here, this ventilation system 1 corresponds to one specific example of a transmission system of the present invention.

[0078] The ventilation devices 100A and 100B have a similar configuration to the ventilation device 100 described in the above embodiment. The cooking devices 200A and 200B have a similar configuration to the cooking device 200 described in the above embodiment.

[0079] The transmitting device 400 is connected to the ventilators 100A and 100B and the electronic device 300 via a network, for example. The transmitting device 400 is configured by, for example, a server or the like. The transmitting device 400 receives abnormality information output from each of the ventilators 100A and 100B, and transmits the received abnormality information to the electronic device 300. The transmitting device 400 functions as a receiving unit 411 and a transmitting unit 412, for example, by reading a program and executing processing.

[0080] The receiving unit 411 receives the abnormality information output from each of the ventilation devices 100A and 100B. The receiving unit 411 receives the abnormality information output from the ventilation device 100A and the abnormality information output from the ventilation device 100B while distinguishing them from each other.

[0081] The transmitting unit 412 transmits the abnormality information received by the receiving unit 411 to the electronic device 300. The transmitting unit 412 is configured to be able to distinguish the abnormality information output from the ventilation device 100A from the abnormality information output from the ventilation device 100B and transmit the abnormality information to one electronic device 300. This makes it easier for one watcher to watch over subjects living in multiple residences. For example, the ventilation device 100A and the cooking appliance 200A are arranged in the watcher's home, and the ventilation device 100B and the cooking appliance 200B are arranged in the residence of the watcher's parents.

[0082] The electronic device 300 receives the abnormality information transmitted by the transmission unit 412. For example, the electronic device 300 distinguishes between the abnormality information output from the ventilation device 100A and the abnormality information output from the ventilation device 100B and displays a predetermined screen on the display unit 330. This allows the watcher to easily know whether the abnormality has occurred at his or her own home or at his or her parents' residence.

[0083] In this manner, in the ventilation system 1 according to the modified example, as in the above embodiment, the presence or absence of an abnormality in the living situation of the subject is determined based on surrounding information on the state around the ventilation device 100. Therefore, it becomes possible to detect an abnormality in the living situation of the person being watched over.

[0084] In addition, since the ventilation system 1 includes the transmitting device 400, it is possible to transmit the abnormality information output from the ventilation devices 100A, 100B disposed in each of the multiple residences to one electronic device 300. This makes it easier for the watcher to watch over the multiple residences.

[0085] The ventilation system 1 may be composed of one ventilation device (for example, ventilation device 100A), one cooking appliance (for example, cooking appliance 200A), and transmission device 400. The ventilation system 1 may transmit the abnormality information output from the ventilation device 100A and the abnormality information output from the ventilation device 100B to a plurality of electronic devices 300 (see FIG. 8). Alternatively, the ventilation system 1 may transmit the abnormality information output from the ventilation device 100A to the electronic device 300, and transmit the abnormality information output from the ventilation device 100B to another electronic device.

[0086] The ventilation device and ventilation system of the present invention have been described above in the embodiments and modified examples. However, the present invention can be appropriately added to, modified, and omitted by a person skilled in the art within the scope of the technical concept. For example, the configurations, shapes, sizes, etc. of the components of the ventilation device and ventilation system described in the above embodiments are merely examples, and other configurations, shapes, sizes, etc. may be used.

[0087] For example, in the above embodiment, the ventilator 100 is a specific example of the kitchen apparatus of the present invention, but the cooker 200 may constitute the kitchen apparatus of the present invention.

[0088] In addition, in the above embodiment, an example was described in which the ventilation device 100 and the cooking appliance 200 each have the sensor 190 and the sensor 270, but a sensor that detects the condition around the ventilation device 100 may be provided outside the ventilation device 100 and the cooking appliance 200.

[0089] In the above modified example, the transmitting device 400 and the ventilation devices 100A, 100B are provided separately. However, at least one of the ventilation devices 100A, 100B may have the transmitting device 400. [Explanation of symbols]
