[0049] As shown in FIG. 5, an area 20a where the air cleaner 20 is installed is registered in the server 10. The registered area 20a is stored in the storage 104. The area 20a is registered using the smartphone 40. The area 20a may be registered by other methods. In FIG. 5, the case where the area 20a is "A" is illustrated.

[0050] In the server 10, areas 30a to 39a where the air cleaners 30 to 39 are respectively installed are registered. The registered areas 30a to 39a are stored in the storage 104. The areas 30a to 39a are respectively registered using the smartphones of the users who use the air cleaners 30 to 39. The areas 30a to 39a may be registered by other methods. In FIG. 5, the cases where the areas 30a to 39a are respectively "A", "B", "A", "A", "B", "A", "A", "A", "A" and "A" are illustrated.

[0051] Server 10 may identify the area where each air purifier 70 is installed from the Internet Protocol (IP) address of each air purifier 70. Each air purifier 70 may transmit the position measured by a positioning device provided in each air purifier 70, and server 10 may receive the transmitted position and identify the area where each air purifier 70 is installed from the received position.

[0052] The air purifier 20 transmits the usage status of the air purifier 20 to the server 10. The transmitted usage status of the air purifier 20 includes the operation content 20b of the air purifier 20. The transmitted usage status of the air purifier 20 may include the usage status of the air purifier 20 other than the operation content 20b of the air purifier 20. The operation content 20b of the air purifier 20 includes the air volume 20c of the air sent by the blower unit 701 provided in the air purifier 20 and the on / off 20d of humidification performed by the humidifying unit 703 provided in the air purifier 20. The operation content 20b of the air purifier 20 may include the operation content of the air purifier 20 other than the air volume 20c and the on / off 20d of humidification. FIG. 5 illustrates a case where the air volume 20c is "automatic" and the on / off 20d of humidification is "on".

[0053] Air purifiers 30 to 39 each transmit the usage status of air purifiers 30 to 39 to server 10. The usage status of air purifiers 30 to 39 to be transmitted each includes the operation contents 30b to 39b of air purifiers 30 to 39. The usage status of air purifiers 30 to 39 to be transmitted may each include the usage status of air purifiers 30 to 39 other than the operation contents 30b to 39b of air purifiers 30 to 39. The operation contents 30b to 39b of air purifiers 30 to 39 each include the air volume 30c to 39c of the air sent by the blower unit 701 provided in air purifiers 30 to 39, and each include the on / off 30d to 39d of humidification performed by the humidification unit 703 provided in air purifiers 30 to 39. The operation contents of air purifiers 30 to 39 may each include the operation contents of air purifiers 30 to 39 other than the air volume 30c to 39c and the on / off 30d to 39d of humidification. In FIG. 5, the air volumes 30c to 39c are respectively "pollen", "silent", "pollen", "pollen", "pollen", "pollen", "silent", "pollen", "auto", and "pollen", and the on / off 30d to 39d of humidification are respectively "off", "off", "on", "off", "off", "on", "off", "off", "off", and "off" as an example.

[0054] Server 10 receives the usage status of the transmitted air purifier 20 and stores the received usage status of air purifier 20 in storage 104.

[0055] Server 10 receives the usage status of the transmitted air purifiers 30 to 39 and stores the received usage status of air purifiers 30 to 39 in storage 104.

[0056] Server 10 acquires the statistics 10a of the usage status of all or part of the memorized air purifiers 30 to 39. The usage status on which the acquired statistics 10a are based is the usage status of a plurality of air purifiers 30, 32, 33, 35, 36, 37, 38, and 39 installed in the same area as the area 20a where the air purifier 20 is installed. The usage status on which the statistics 10a are based may be the usage status of a plurality of air purifiers other than the plurality of air purifiers 30, 32, 33, 35, 36, 37, 38, and 39 installed in the same area as the area 20a where the air purifier 20 is installed. For example, when the air purifiers 20 and 30 to 39 each include the usage time of the air purifiers 20 and 30 to 39, the usage status on which the statistics 10a are based may be the usage status of a plurality of other air purifiers having a usage time similar to the usage time of the air purifier 20.

[0057] The statistics 10a include the increase rate of specific operating contents included in the operating contents of the air purifiers 30, 32, 33, 35, 36, 37, 38, and 39. The increase rate is the increase rate at a set time or the like. In FIG. 5, the increase rate of "pollen" is +25%, the increase rate of "automatic" is -12.5%, the increase rate of "silent" is -12.5%, the increase rate of "in" is -25%, and the increase rate of "off" is +25% are illustrated as examples.

[0058] Server 10 determines the proposed content 10b regarding the operation performed by the air purifier 20 based on the acquired statistics 10a. Server 10 includes the specific operating content in the proposed content 10b when the increase rate of the specific operating content is greater than the reference increase rate. In FIG. 5, "pollen" and "off" having an increase rate of +25% greater than the reference increase rate of +20% are illustrated as examples of being included in the proposed content 10b.

[0059] Server 10 transmits the determined proposed content 10b to the smartphone 40. Server 10 may transmit the proposed content 10b only when the proposed content 10b is different from the operating content of the operation currently being performed by the air purifier 20, and may not transmit the proposed content 10b when the proposed content 10b is the same as the operating content of the operation currently being performed by the air purifier 20.

[0060] The smartphone 40 receives the transmitted proposed content 10b and displays the received proposed content 10b. Thereby, the user 50 can be prompted to cause the air cleaner 20 to perform an operation having the proposed content 10b. The usage situations suitable for the air cleaners 30, 32, 33, 35, 36, 37, 38, and 39 are likely to also be usage situations suitable for the air cleaner 20. Therefore, the proposed content 10b determined based on the usage statistics 10a of the air cleaners 30, 32, 33, 35, 36, 37, 38, and 39 is likely to be an operation content suitable for the air cleaner 20. Accordingly, by displaying the proposed content 10b, the user 50 can be prompted to cause the air cleaner 20 to perform an operation suitable for the air cleaner 20. This becomes particularly prominent when the usage situations on which the statistics 10a are based are the plurality of air cleaners 30, 32, 33, 35, 36, 37, 38, and 39 installed in the same area as the area 20a where the air cleaner 20 is installed. The proposed content 10b to be displayed is, for example, a message such as "Many people in the same area are using the pollen operation, so it is recommended."

[0061] The server 10 may transmit an instruction 10c to cause the air cleaner 20 to perform an operation having the determined proposed content 10b to the air cleaner 20. In this case, the air cleaner 20 receives the transmitted instruction 10c and performs an operation according to the received instruction 10c. For example, as shown in FIG. 5, when "pollen" and "on" are included in the proposed content 10b, the air cleaner 20 sets the air volume to "pollen" and sets the humidification on / off to "on".

[0062] 1.6 Flow of processing FIG. 6 is a flowchart showing the flow of processing performed by a server provided in the notification system of the first embodiment.

[0063] The server 10 executes steps S101 to S106 shown in FIG. 6.

[0064] In step S101, the processor 102 causes the communication unit 101 to receive from each of the air purifiers 30, 32, 33, 35, 36, 37, 38, and 39 the usage status thereof.

[0065] In the subsequent step S102, the processor 102 refers to regions 20a and 30a to 39a in which the air purifiers 20 and 30 to 39 are respectively installed and which are stored in the storage 104. Based on the referred regions 20a and 30a to 39a, the processor 102 extracts from the received usage statuses of the air purifiers 30, 32, 33, 35, 36, 37, 38, and 39 the usage statuses of the air purifiers 30, 32, 33, 35, 36, 37, 38, and 39 installed in the same region as the region 20a in which the air purifier 20 is installed.

[0066] In the subsequent step S103, the processor 102 obtains a statistic 10a of the extracted usage statuses of the air purifiers 30, 32, 33, 35, 36, 37, 38, and 39.

[0067] In the subsequent step S104, the processor 102 determines a proposed content 10b based on the obtained statistic 10a.

[0068] From step S102 to S104, the processor 102 determines the proposed content 10b based on the statistic 10a of the usage statuses of the air purifiers 30, 32, 33, 35, 36, 37, 38, and 39 installed in the same region as the region 20a in which the air purifier 20 is installed.

[0069] In the subsequent step S105, the processor 102 causes the communication unit 101 to transmit the determined proposed content 10b to the smartphone 40.

[0070] In the subsequent step S106, the processor 102 causes the communication unit 101 to transmit to the air purifier 20 an instruction to cause the air purifier 20 to perform an operation including the determined proposed content 10b.

[0071] 1.7 Advantages of the notification system According to the notification system 1, for example, even if the user 50 has not set the air volume to "pollen" despite knowing that a large amount of pollen is scattered, when many users in the same area have set the air volume to "pollen", the user 50 can recognize this. Therefore, the possibility that the user 50 sets the air volume to "pollen" increases. This is because the user 50 feels psychologically at ease if they do the same thing as the users in the same area. Thereby, it is possible to prompt the user 50 to cause the air purifier 20 to perform an operation suitable for the air purifier 20.

[0072] Also, according to the notification system 1, for example, when many users in the same area start setting the humidification on / off to "on" at the turn of the season or the like, the user 50 can recognize this. Thereby, it is possible to prompt the user 50 to set the humidification on / off to "on" and to perform preparations for setting the humidification on / off to "on". The said preparations are, for example, cleaning of the humidification filter etc. In addition, when a weather forecast is acquired and a proposal is made based on the acquired weather forecast, when the weather forecast that can be acquired is a weather forecast immediately after the same day, the next day, etc., there is a high possibility that the preparations will not be in time.

[0073] 2 Second Embodiment Hereinafter, the differences between the second embodiment and the first embodiment will be described. For points not described, the same configurations as those employed in the first embodiment are also employed in the second embodiment.

[0074] FIG. 7 is a diagram showing information processed by the notification system of the second embodiment.

[0075] In the second embodiment, as shown in FIG. 7, the acquired statistic 10a includes the ratio of a specific operation content included in the operation contents of the air purifiers 30, 32, 33, 35, 36, 37, 38, and 39. The ratio is, for example, the ratio of the specific operation content to all the operation contents. FIG. 7 illustrates a case where the ratio of "pollen" is 75%, the ratio of "automatic" is 12.5%, the ratio of "silent" is 12.5%, the ratio of "on" is 25%, and the ratio of "off" is 75%.

[0076] When the ratio of the specific operation content is greater than the reference ratio, the server 10 includes the specific operation content in the proposed content 10b. FIG. 5 illustrates a case where "pollen" and "off" having a ratio of 75% greater than the reference ratio of 70% are included in the proposed content 10b.

[0077] The present disclosure is not limited to the above embodiments, and may be replaced with a configuration that is substantially the same as the configuration shown in the above embodiments, a configuration that exhibits the same operational effects, or a configuration that can achieve the same purpose.
