  The odor sensor 212 and the dust sensor 213 are sensors for detecting the degree of air contamination.

  The odor sensor 212 detects the concentration of gas (particles) that causes air contamination. The odor sensor 212 typically detects the concentration in the air of ammonia, formaldehyde, carbon monoxide, or the like. The odor sensor 212 sends the detection result to the control device 210. In the air cleaner, a plurality of odor sensors may be provided depending on the type of gas to be detected.

  In the odor sensor 212, when odor molecules are adsorbed on the surface of a sensor made of a metal oxide semiconductor, the electrical conductivity increases and the resistance value decreases. The odor sensor 212 detects the change in the electrical resistance value and determines the concentration of the odorous substance. The measurement of odor is not limited to such a measurement method.

  The dust sensor 213 detects the dust concentration by detecting the amount of dust that causes air contamination. Typically, the dust sensor 213 detects the concentration in the air, such as pollen and a fine particulate matter (PM2.5) of 2.5 μm or less, using an issuing element and a light receiving element. The dust sensor 213 sends the detection result to the control device 210.

  There are a plurality of methods for obtaining the position information of the air purifier 200. The explanation is as follows.

  As a first method, the server apparatus 100 uses the address information in the user registration information received on the manufacturer's web page, and uses the address as position information.

  As a second method, the server apparatus 100 receives position information from the air purifier 200. As the position information, latitude and longitude by GPS can be used. In this case, the air purifier 200 needs to be equipped with a GPS reception antenna. Alternatively, the user may input a zip code using the operation panel 211, and the air cleaner 200 may transmit the input zip code to the server apparatus 100. In this case, the server apparatus 100 acquires a rough address from the zip code and uses the address as position information.

  In addition, the transmission timing of latitude / longitude information and the transmission timing of the postal code are not particularly limited. The air purifier 200 may be configured to transmit latitude / longitude information or a zip code to the server device 100 based on a user's transmission operation. Alternatively, for example, the air purifier 200 may include these pieces of information in a data frame used when transmitting the detection result.

  The server device 100 may further use the altitude information of GPS according to the latitude and longitude information.

  As a third method, the server apparatus 100 may use information on the installation location of the wireless router (access point) as position information. As a fourth method, the air purifier 200 performs pairing with another electronic device (TV, smartphone) in the building, thereby transmitting the position information of the other electronic device to the server device 100. There may be.

  As described above, the information system 1 includes the server device 100 and the plurality of air purifiers 200. Each air cleaner 200 detects the degree of air contamination and transmits the detection result to the server device 100. The server apparatus 100 manages the detection result in association with the ID (identification information) of the air cleaner 200. According to such a configuration, the operator of the server apparatus 100 can easily obtain information on air pollution.

  Moreover, the server apparatus 100 acquires the positional information showing the installation position of each air cleaner 200, and manages the said detection result further linked | related with positional information. According to such a configuration, the operator of the server apparatus 100 can know the relationship between the contamination status and the contamination location.

Hereinafter, a method of using the detection result acquired by the server apparatus 100 will be described.
(C2. Notification and notification)
The server apparatus 100 refers to the data table D4 and executes one of the following processes.

(1) First Processing Example The server apparatus 100 identifies an air cleaner 200 having a degree of air contamination exceeding a predetermined standard from among a plurality of air cleaners 200. Specifically, the server device 100 refers to the data table D4, and from among the plurality of air purifiers 200, the air purifier 200 in which the odor concentration (value) is equal to or higher than a reference value, The air cleaner 200 whose density (value) is equal to or higher than the reference value is specified. The odor reference value and the dust reference value are typically set individually.

  The server apparatus 100 causes the specified air purifier 200 to execute a predetermined notification. Specifically, by transmitting a predetermined command to the specified air purifier 200, the server apparatus 100 causes the air purifier 200 to output by voice that the air is particularly dirty. . Further, the server device 100 may cause the air purifier 200 to output the content for proposing filter replacement by voice.

  By causing the air cleaner 200 to execute such notification, the user of the specified air cleaner 200 visually recognizes that the air in the building such as home is particularly dirty on the display of the operation panel 211. Compared with, it can be recognized more clearly. In addition, it is good also as a structure which displays the content by said audio | voice on the operation panel 211 instead of an audio | voice.

  Further, the “predetermined standard” described above may be set for each region. For example, the standard may be set higher in urban areas, and the standard may be set lower in suburbs such as the countryside. According to such a configuration, it is possible to perform processing in consideration of regional characteristics. Note that the server device 100 determines to which region the air purifier 200 belongs based on the position information.

(2) Second processing example The server device 100 may be a smartphone or the like registered in advance by a user of the specified air purifier 200 instead of causing the specified air purifier 200 to execute a predetermined notification. A predetermined notification (typically, a message) is transmitted to the electronic device. Specifically, the server apparatus 100 transmits an e-mail for notifying the user that the air is particularly dirty to the electronic device. Moreover, the server apparatus 100 may transmit the email containing the content which proposes filter replacement | exchange to the air cleaner 200 addressed.

  By performing such notification to the electronic device, the specified user of the air cleaner 200 recognizes that the air in the building such as home is particularly dirty by means other than the air cleaner 200. be able to. Note that the server device 100 may perform the first processing example together with the second processing example.

(3) Third Processing Example The server apparatus 100 specifies a predetermined number of the air purifiers 200 that are installed in the same area in order of the degree of air contamination.

  When the air cleaner 200 is specified in this way, the server device 100 causes the air cleaner 200 to execute a predetermined notification in the same manner as described in the first processing example. Further, as described in the second processing example, a predetermined notification is transmitted to an electronic device such as a smartphone registered in advance by the user of the specified air purifier 200. The server device 100 may be configured. Further, in the case of this configuration, the indoor (indoor) air may be informed or notified as compared to the air in a nearby building.

  According to such a configuration, it is possible to alert or make a suggestion to the user of the air purifier 200 who lives in a building where indoor air is particularly dirty among buildings in the same region.

(C3. Creation and use of maps)
In addition to the notification or notification described above, the server device 100 refers to the data table D4 to create a pollution map that represents the indoor air pollution status and a pollution map that represents the outdoor air pollution status. create.

(1) Creation of pollution map representing indoor air pollution status The server apparatus 100 includes a detection result by the odor sensor 212 and a detection result by the dust sensor 213 of each air purifier 200, position information of the data table D4, Based on the map data D5 (see FIG. 6) stored in advance, a map showing the degree of dirt (contamination status) for each door (by building) is created. The map data D5 is data for separately displaying a building such as a house. As the map data D5, for example, house map data can be used.

  Specifically, the server device 100 includes an odor contamination map using the detection result by the odor sensor 212, a dust contamination map using the detection result by the dust sensor 213, a detection result by the odor sensor 212, and a detection result by the dust sensor 213. Create an odor and dust pollution map using.

(I) Odor Pollution Map When the server apparatus 100 creates an odor pollution map, the display mode of a graphic representing a building on the map is changed to a display mode corresponding to the pollution level indicated by the detection result by the odor sensor 212. .

  For example, when the detection result indicates a strong odor, the server apparatus 100 displays the building in which the air purifier 200 that has detected such a result is installed in a first mode (for example, red). . Moreover, when the detection result represents a moderate odor, the server apparatus 100 displays the building in which the air purifier 200 that has detected such a result is installed in the second mode (for example, yellow). indicate. Moreover, when the detection result represents weak odor, the server apparatus 100 displays the building in which the air purifier 200 that has detected such a result is installed in a third mode (for example, green). .

  Note that the server apparatus 100 keeps a default state (typically white) for a building from which the detection result by the odor sensor 212 is not obtained.

  According to such an odor pollution map, it is possible to easily visually determine which building's room is contaminated by odor.

(Ii) Dust Contamination Map When creating the dust contamination map, the server device 100 changes the display mode of the graphic representing the building on the map to a display mode corresponding to the contamination level indicated by the detection result by the dust sensor 213. .

  FIG. 5 is a diagram showing an example of the dust contamination map. Referring to FIG. 5, server device 100 displays a building in which air cleaner 200 that has detected a large amount of dust is installed in a first mode (in the case of FIG. 5, bold hatching). Moreover, the server apparatus 100 displays the building in which the air purifier 200 that has detected a medium amount of dust is installed in the second mode (in the case of FIG. 5, thin line hatching). Furthermore, the server apparatus 100 displays the building in which the air purifier 200 that has detected a small amount of dust is installed in a third mode (in the case of FIG. 5, hatching with thin lines with wide intervals).

  According to such a dust contamination map, it is possible to easily visually determine which building's room is contaminated with dust.

(Iii) Odor and Dust Contamination Map When the server apparatus 100 creates the odor and dust pollution map, the pollution level indicated by the detection result by the odor sensor 212 and the dust sensor 213 indicate the display mode of the graphic representing the building in the map. The display mode is changed in consideration of the contamination level indicated by the detection result of. For example, when each of the pollution level due to odor and the pollution level due to dust is classified into three stages, the server apparatus 100 classifies the pollution levels into six stages by summing up each pollution level. The server apparatus 100 changes the display mode of the graphic representing the building on the map to a display mode corresponding to the six levels of division (level).

  According to such a dust contamination map, it is possible to easily visually determine which building's room is contaminated.

(2) Contamination map showing the outdoor air pollution status The detection result of the air cleaner 200 is influenced by the outside air. For example, when a window is opened for ventilation, contaminants in the outside air enter the room. Also, contaminants in the outside air enter the room by opening and closing the entrance door.

  Therefore, the detection result of the air cleaner 200 can be correlated with the contamination of the outside air. In particular, if the detection results of a plurality of air purifiers 200 in the same area are used, the state of contamination of the outside air can be determined.

  Therefore, the server apparatus 100 creates a pollution map (hereinafter also referred to as “air pollution map”) representing the degree of outdoor air contamination (contamination status) with reference to the data table D4. For example, the server device 100 applies a color scheme according to the contamination level to the entire map displayed based on the map data D5.

  When determining the outdoor pollution level in a certain area, the server device, as an example, detects a plurality of detection results excluding specific detection results from the detection results obtained by the plurality of air purifiers 200 installed in the area. The average of the results can be used.

  Note that the area includes an area (for example, chome) smaller than a municipality or a ward. Further, when the number of data obtained in one region is small, the server device 100 may be configured so that a region larger than the region is set as one region.

  According to the server apparatus 100, it is possible to create an air pollution map by using the detection result of the air cleaner 200.

  Further, when the server device 100 further uses the altitude information of GPS as described above, it is possible to create an air pollution map for each altitude.

(3) Another method of using the pollution map In order for the user of the air cleaner 200 to use the created pollution map (odor pollution map, dust pollution map, odor and dust pollution map, air pollution map), the server apparatus 100 May send the pollution map to an electronic device such as the smartphone 300 owned by the user.

  Moreover, in order for a third party to utilize the created pollution map, it may be provided (for example, sold) to the third party. Such provision can be performed, for example, when the server apparatus 100 transmits the contamination map data to an information processing apparatus such as a personal computer owned by a third party.

[Embodiment 2]
In the present embodiment, server device 100 creates an air pollution map after a predetermined time in addition to the four pollution maps described above.

  FIG. 8 is a diagram showing a schematic configuration of information system 1A according to the present embodiment. Referring to FIG. 8, information system 1A is different from information system 1 (FIG. 1) according to Embodiment 1 in that information system 1A further includes a server device 500 that is communicably connected to server device 100.

  The server device 500 is a device operated by the Japan Meteorological Agency or a weather company. The server device 500 stores weather information for various parts of the country.

  The server device 100 acquires wind information for each region from the server device 500. Specifically, the server apparatus 100 acquires information on the wind speed and the wind direction. The server apparatus 100 further creates a prediction map indicating that the outdoor air pollution status after a predetermined time has elapsed based on the wind information and the detection results of the odor sensor 212 and the dust sensor. . For example, the server apparatus 100 creates a prediction map after one hour for each region.

  The server apparatus 100 typically transmits a prediction map of an area where the air purifier is installed to each smartphone 400. Note that the server device 100 may transmit the prediction map to a cleaning company or the like.

  According to such a configuration, the user of each air cleaner 200 can know in advance the contamination status of the outside air after a predetermined time has elapsed. Therefore, when it is predicted that the contamination will become severe, the user takes a precaution such as changing the operation mode of the air purifier 200 to a mode in which the cleaning function is strengthened or refraining from opening and closing the window. be able to.

[Embodiment 3]
In the present embodiment, server apparatus 100 uses a degree of indoor (indoor) air contamination and an outdoor air (outside air) contamination degree to search for a building where indoor air is locally contaminated.

  For example, the server apparatus 100 compares the detection results of the odor sensor 212 and the dust sensor 213 shown in the data table D4 described above with the degree of dirt in outdoor air (outside air). Specifically, the server apparatus 100 acquires the measurement result from the server apparatus that stores the measurement result of air pollution for each region, and the detection result from the plurality of air purifiers 200 is a reference value than the measurement result. The high air cleaner 200 is specified above.

  Such a comparison is performed because the degree of contamination of the outside air varies depending on the region. For example, in urban areas and suburbs, urban areas have a higher degree of outside air pollution. In order to consider such regional circumstances, the server device 100 uses the degree of dirtiness of the outside air.

  In this embodiment, an air pollutant wide area monitoring system operated by the country (Ministry of the Environment) can be used instead of the server device 500. Specifically, the server apparatus 100 acquires information representing the degree of contamination of outdoor air (outside air) in various places from the server apparatus of the air pollutant wide area monitoring system.

  The server apparatus 100 specifies the position of the building where the indoor air is more dirty than the reference value by the position information of the air cleaner 200. If the air purifier 200 is operating, the indoor air should normally be less dirty than the outside air. Nevertheless, the reason why the indoor air is more dirty than the outside air is because the filter of the air purifier 200 is deteriorated or the room is not properly cleaned.

  Therefore, various businesses can be developed by using information on buildings that are locally dirty in this way. For example, such information can be sold to a cleaner. In addition, the manufacturer of the air cleaner 200 can prompt the user to replace the filter. For example, the server apparatus 100 can send an e-mail that suggests replacing the filter to the user's smartphone 400 or the like. Or the server apparatus 100 outputs the audio | voice which urges | exchanges a filter from the speaker 214 of the air cleaner 200 by sending a command to the air cleaner 200 installed in a locally dirty room. According to such a configuration, indoor air can be kept clean.

[Embodiment 4]

  The air conditioner 600a is installed in the same building as the air purifier 200a. The air conditioner 600a includes an indoor unit 601a and an outdoor unit 602a. The outdoor unit 602a is provided with an odor sensor and a dust sensor. That is, the odor sensor and the dust sensor are installed outside the room where the air purifier 200 is provided.

  The odor sensor detects the concentration of gas (particles) that causes dirt in the outside air. The dust sensor detects the dust concentration by detecting the amount of dust that causes dirt in the outside air. The detection result by the odor sensor and the detection result by the dust sensor are periodically transmitted to the server apparatus 100 via the indoor unit 601a and the wireless router 300a. In addition, when the transmission period Td of the detection result of the air cleaner 200 is long, it is preferable that transmission of the detection result by the outdoor unit 602a and transmission of the detection result of the air cleaner 200 are synchronized.

  The air conditioner 600b includes an indoor unit 601b and an outdoor unit 602b. The air conditioner 600c includes an indoor unit 601c and an outdoor unit 602c. The air conditioner 600d includes an indoor unit 601d and an outdoor unit 602d. The outdoor units 602b, 602c, and 602d include an odor sensor and a dust sensor as with the outdoor unit 602a, and transmit detection results to the server apparatus 100 as with the outdoor unit 602a.

  The server apparatus 100 uses the detection results acquired from the outdoor units 602a, 602b, 602c, 602d,... As the measurement results of air pollution for each region. This eliminates the need for the server device 100 to acquire information representing the degree of contamination of outdoor air (outside air) in various locations from the server device of the air pollutant wide area monitoring system.

Even with such a configuration, the same effect as in the third embodiment can be obtained.
