The air-cleaning control unit 11 transmits information to the server 20 via the communication unit 12 every predetermined time (for example, every 15 minutes). The air purification control unit 11 transmits information to the server 20 each time there is an irregular change in the detection information, or when operation is started, stopped, the operation type is changed, the operation mode is changed, etc. .

(Configuration of server 20)
As shown in FIG. 2, the server 20 includes a server control section 21 that controls the operation of each section of the server 20, a communication section 22, a storage section 23, and the like. The communication unit 22 enables communication between the server 20 and external devices (communication terminal 30, external server 43, air cleaner 10, etc.). The storage unit 23 stores various information and programs necessary for the operation of the server 20 .

The server control unit 21 is a computer device configured by, for example, an arithmetic processing unit such as a CPU and a dedicated processor, and controls the operation of each unit of the server 20 according to information and programs stored in the storage unit 23 . The information notification unit 24 described above is constructed in the server control unit 21 .

As described above, the information notification unit 24 estimates the impact of the disaster on the space where the air cleaner 10 is installed based on the detection information acquired from the sensor unit 15 provided in the air cleaner 10, and performs the estimation. to the communication terminal 30 capable of communicating with the air purifier 10. The estimation method and the like will be described later, but the information notification unit 24 compares the information detected by the sensor unit 15 before and after the occurrence of the disaster, and estimates the impact of the disaster by considering the presence or absence of change or the degree of change. Based on the estimation, the information notification unit 24 notifies, as message information corresponding to the estimation, information useful for estimating the impact of a disaster on one's home from outside.

Further, in the present embodiment, when the information notification unit 24 receives from the external server 43 disaster occurrence information indicating that a disaster has occurred in the area where the air purifier 10 is installed, the information notification unit 24 receives detection information acquired after the disaster occurs. Estimate impact based on information and notify message information.

In the case of a system in which a postal code is entered when registering a combination of the air purifier 10 and the communication terminal 30 in the server 20, the area where the user's home 41 is located is included in the disaster occurrence information area based on the postal code. It is possible to determine whether or not Also, whether or not the detection information was acquired after the occurrence of a disaster can be determined by comparing the information on the occurrence time included in the disaster occurrence information and the information on the acquisition time of the detection information. The storage unit 23 stores information necessary for the information notification unit 24 to judge, estimate, and transmit message information.

The information notifying unit 24 notifies such message information within a short period of time, for example, within five minutes after receiving the disaster information. As a result, the user who receives the notification of the message information can estimate the impact on his/her home from outside within a short period of time after the occurrence of the disaster, and take necessary countermeasures.

In addition, in the present embodiment, the information notification unit 24 proposes to stop the air purifier 10 together with notification of the message information as one of necessary countermeasures, and accepts a stop instruction. That is, when the user selects stop, an operation screen (see FIG. 7), which will be described later, for accepting an operation to start the application and stop the air purifier 10 is displayed.

Further, in this embodiment, the information notification unit 24 notifies the latest detection value of the sensor included in the sensor unit 15 or change information of the detection value together with the message information. As a result, the user who received the notification can confirm the detected value, and can more accurately estimate the impact on his or her home.

Further, in the present embodiment, when communication with the air cleaner 10 is interrupted, the information notification unit 24 waits until the notification is recovered, and when the communication is recovered, based on the detection information acquired after recovery. to estimate the impact of disasters and notify message information.

This is based on the assumption that a power outage occurs at the user's home 41 during a disaster. When a power failure occurs, the repeater 40 becomes unable to communicate, and the communication between the air cleaner 10 and the server 20 is interrupted. In this case, since the detection information after the disaster is not transmitted to the server 20, the detection information acquired after the occurrence of the disaster cannot be acquired, and the information notification unit 24 cannot estimate the impact of the disaster.

Therefore, in the event of a communication disruption, when communication is restored, by estimating the impact of the disaster based on the detection information acquired after recovery and notifying message information, useful message information is notified to the user even when communication is disrupted. can do.

Here, the information notification unit 24 determines whether the communication has been restored and estimates the influence when the communication is restored and transmits the message information. , together with the detected information, the information notifying unit 24 may be instructed to notify the message information.

Furthermore, in the present embodiment, after a predetermined period of time has passed since the notification of the message information, the information notification unit 24 estimates the impact of the disaster on the basis of the detection information acquired after the notification of the message information. Notify the follow-up message information. The detection information acquired after notification of the message information is the detection information already acquired at the time when the predetermined time has passed, or the detection information newly acquired at that time.

Such a follow-up report can be sent, for example, after a predetermined period of time, for example, 1 hour after receiving the disaster information. It is meaningful to receive the follow-up notification while the user is out of the office. Therefore, it is preferable to wait about 30 minutes to 1 hour after notification of the first report. Note that the follow-up report may be sent multiple times.

By being notified of the follow-up message information, the user can estimate the impact on the home based on the new information. Therefore, it is possible to take more effective measures before returning home, and it is possible to quickly know when the effects have been improved.

(Configuration of communication terminal 30)
The communication terminal 30 includes a terminal control section 31 that controls the operation of each section of the communication terminal 30, a communication section 32, a storage section 33, a display section 34, an input section 35, an audio output section 36, an oscillation section 37, and the like. The communication unit 32 enables communication between the communication terminal 30 and an external device (server 20, another communication terminal, etc.). The storage unit 33 stores various information and programs necessary for the operation of the communication terminal 30 .

The display unit 34, the audio output unit 36, and the oscillation unit 37 are notification units that notify the user of information. The display unit 34 notifies the content of the notification information or the presence of the notification information by displaying characters, images, etc., the voice output unit 36 by sound or voice, and the oscillation unit 37 by vibrating the communication terminal 30 . The input unit 35 receives an instruction input from the user, such as an input using a key or button, an input using a touch operation using the display unit 34, an audio input using a microphone, or the like.

The terminal control unit 31 is a computer device configured by an arithmetic processing unit such as a CPU and a dedicated processor, and controls the operation of each unit of the communication terminal 30 according to information and programs stored in the storage unit 33 . An air cleaning operation unit 38 and a notification control unit 39 are constructed in the terminal control unit 31 .

The air cleaning operation unit 38 receives operations of the air cleaner 10 . The air-cleaning operation unit 38 is constructed by a dedicated application or the like downloaded to the communication terminal 30 . The air purification operation unit 38 displays an operation screen for operating the air purifier 10 on the display unit 34 and receives an instruction input using the operation screen. The contents of the instruction received by the air purification operation unit 38 are transmitted to the air purifier 10 via the server 20, and the air purifier 10 executes the instructed operation.

The notification control unit 39 controls the above-described notification units (the display unit 34, the audio output unit 36, and the oscillation unit 37), and when message information is notified from the server 20, the message information is activated at the timing at which it is received. to inform Here, active notification means displaying on the screen of the display unit 34 using the notification function of the communication terminal 30, for example. To display using the notification function means to notify as a notification.

As a result, a state in which a dedicated application for operating the air purifier 10 is not started (a state in which the operation screen is not opened), a state in which the screen is locked, or an image of another application is displayed on the screen. Even when displayed, the message information received from the server 20 can be notified to the user.

In this case, it is more preferable to use the voice output unit 36 and/or the oscillation unit 37 to display the message information on the display unit 34 together with the ring tone and/or vibration. If the notification unit is equipped with a light-emitting unit such as an LED, the light-emitting unit may also be used.

Further, even when message information is notified while the operation screen of the air purifier 10 is displayed, the notification control unit 39 displays the message information conspicuously by, for example, popping up the operation screen.

(Estimation and message information by the information notification unit 24)
Next, the method of estimation by the information notification unit 24 and the message information according to the estimation will be described with reference to FIG. FIG. 3 is an explanatory diagram showing a method for estimating the impact of a disaster on the installation space of the air purifier 10 based on the information detected by the sensor unit 15 and an example of message information by the information notification unit 24 .

As shown in FIG. 3, the information notification unit 24 includes a room temperature sensor, a humidity sensor, a dust sensor, an odor sensor, a PM2.5 sensor, an illuminance sensor, and a humidification tank water level sensor, which are included in the sensor unit 15 of the air purifier 10. , the rear panel sensor, and the PCI ion unit sensor. For example, it is estimated as follows from changes in room temperature and humidity.

<See No. 1 and No. 2 in Fig. 3>
For the room temperature sensor and humidity sensor, changes in the detected values are combined to estimate window cracks and air conditioner stoppages.

When the room temperature and humidity both change from low to high, it is estimated that the window may have been broken in the summer. In other words, it can be estimated that such a state change is a state in which outside air enters a room that is air-conditioned in summer, and that the window is open or broken.

When the room temperature and humidity both change from high to low, it is estimated that the window may have been broken in winter. In other words, it can be estimated that such a state change is a state in which outside air enters a heated room in winter, and the window is open or broken.

When such estimation is performed, the information notifying unit 24 notifies message information such as "The temperature and humidity are suddenly changing (the window may be open). I'll wait and see." I).

When the room temperature changes from low to high and the humidity changes from high to low, it is estimated that the air conditioner in the same room may have stopped working in summer. In other words, such a state change is assumed to be a state in which the air conditioner stops in the summer, the room temperature rises, and the absolute humidity in the room does not change, but the relative humidity drops as the room temperature rises, and the air conditioner has stopped. can.

When the room temperature changes from high to low and the humidity changes from low to high, it is estimated that the air conditioner in the same room may have stopped working in winter. In other words, such a state change is assumed to be a state in which the air conditioner stops in winter, the room temperature drops, and the indoor absolute humidity does not change, but the relative humidity rises by the amount of the room temperature drop, and the air conditioner stops. can.

When such estimation is performed, the information notifying unit 24 notifies message information such as "The temperature and humidity are changing suddenly (the air conditioner may have stopped. We will wait and see.") (Notification I ).

In addition to the message information, the notification I includes the latest detected value or change information of the detected value. When you touch the underlined "Sudden change in temperature and humidity" part, the history screen (see Fig. 6), which will be described later, is displayed, and the latest detected value and change information of the detected value are displayed in graphs, etc. and is visually visible.

Then, when a predetermined time has passed after notification I was notified (here, 1 h after receiving the disaster information), the detection information acquired at that time is compared with the detection information when notification I was notified, and the state of notification I is determined. If there is a change such that is considered resolved, the status of notification I is presumed to be resolved. After making such an estimation, the information notification unit 24 notifies follow-up message information such as "The previously notified state has been resolved. Please confirm" (Notification II). On the other hand, if there is no change such that the state of notification I is considered resolved, it is assumed that the state of notification I continues. When such estimation is performed, the information notifying unit 24 notifies message information such as "The state previously notified continues. Please confirm" (Notification II).

In Notification II, along with the message information, the latest detection value or change information of the detection value is also notified. When you touch the given "Please check" part, the history screen (see Fig. 6) is displayed, and the latest detected value and change information of the detected value are displayed in graphs, etc., so that they can be visually recognized. It's becoming

<Refer to No. 3 to No. 5 in Fig. 3>
Regarding the dust sensor, odor sensor, and PM2.5 sensor, based on the same interpretation of the changes in the detected values, it is estimated that objects in the room have fallen over, windows have cracked, fires have occurred, and so on.

When the detected value changes slightly from low to high (1), it is estimated that "something in the room may have fallen over." If the detected value changes significantly from low to high (2), it is estimated that there is a risk of fire. Also, in both (1) and (2), it is estimated that the window may have been broken. If an object in the room falls over or the window is broken, the dust and PM2.5 sensor will rise or enter the room, increasing the detection value. Also, when a fire breaks out, the smoke greatly increases these detection values. Therefore, from such a change in the detection value, it is possible to estimate the overturning of objects in the room, the breakage of windows, the occurrence of fire, and the like. The accuracy of estimation can be improved by estimating changes in the detected values of these sensors in combination with the room temperature.

When such estimation is performed, the information notification unit 24 notifies message information such as "Dust (or odor or PM 2.5) has changed suddenly and greatly, please check" according to the sensor used (notification I). Also in this case, if you touch the underlined "Please check" part of the message text on the notification list screen (see Fig. 5) displaying the message information, the history screen (see Fig. 6) will be displayed. The latest detected value and change information of the detected value are displayed in a graph or the like, and can be visually recognized.

Then, when a predetermined time has passed after the notification I was sent, the detection information acquired at that time is compared with the detection information when the notification I was sent, similarly to the room temperature and humidity described above, and the state of the notification I is determined. Estimate whether the problem has been solved, and send follow-up message information according to the estimate (Notification II).

<Refer to No. 6 to No. 9 in Fig. 3>
From the illuminance sensor, the water amount sensor of the humidification tank, the rear panel sensor, and the PCI ion unit sensor, the fall of the air cleaner 10 is estimated from changes in the detected values.

When the detected value of the illuminance sensor changes from bright to dark or from dark to bright, it is estimated that the air purifier 10 has overturned or a nearby object has fallen or fallen. In other words, such a state change in the detection value of the illuminance sensor means that the amount of light received by the air purifier 10 has changed. can be estimated.

When the detected value of the water quantity sensor changes from yes to no or no to yes, it is estimated that the air purifier 10 has fallen over. It can be estimated that the float detecting water moved against gravity, that is, the air purifier 10 overturned, because the detected value of the water sensor changes state before and after receiving the disaster information.

When the detected value of the rear panel sensor changes from normal to abnormal installation, it is estimated that the air purifier 10 has fallen over. In other words, it can be estimated that the rear panel has come off or the air purifier 10 has fallen over when the state changes like this before and after receiving the disaster information.

As with the rear panel sensor, when the detected value of the PCI ion unit sensor changes from normal to abnormal installation, it is estimated that the air cleaner 10 has fallen over. In other words, it can be estimated that the PCI ion unit has come off or the air purifier 10 has been overturned from such state changes before and after receiving the disaster information.

When such an estimation is made, the information notifying unit 24 outputs "The air purifier or surrounding objects may have fallen or fallen. To stop operation, click here." A part has come off. The air purifier may have fallen over. Click here to stop operation." (notification I). In this case, on the notification list screen (see FIG. 5) displaying the message information, when the user touches the underlined "Click here to stop operation" part of the message text, the air purifier, which will be described later, An operation screen (see FIG. 7) for accepting an operation to stop 10 is displayed.

Then, if the air purifier 10 is not stopped, after a predetermined period of time has elapsed after the notification I was sent, the state around the air purifier 10 is estimated based on the detection information acquired at that time. It notifies message information of follow-up information in response (notification II). For example, "here is the current status of the vicinity of the air purifier" is notified. In this case as well, the current status of the air purifier 10 can be confirmed by touching the underlined "here" portion of the message text on the notification list screen (see FIG. 5) displaying the message information of the follow-up message. An operation screen (see FIG. 7) that can be used is displayed. In Notification I, when the air purifier 10 is stopped, the follow-up message information is not notified.

<Refer to No. 10 in Fig. 3>
If the information detected by the sensor unit 15 does not show any change in the state that can be assumed to be affected by the disaster, the information notification unit 24 will issue a notification I stating, "No environmental change has been detected in the room. We will continue to check." Notify message information.

Estimates the impact of the event and notifies the message information.

With such a configuration, message information can be notified without using disaster occurrence information received from the external server 43 . A communication interruption period that can be a trigger for notification of message information is about 25 to 120 minutes.

When a disaster such as an earthquake or bad weather occurs, a momentary power outage may occur. When such a momentary power failure occurs, the repeater 40 (see FIG. 1) is temporarily stopped and then restarted. Communication between the air purifier 10 and the server 20 then fails. If this failure occurs once, the regular communication is skipped once, and the communication interval originally about every 15 minutes is extended to about 30 minutes. The lower limit of 25 minutes for the interruption period is set so that communication interruption due to such a momentary power failure can be detected. The upper limit of 120 minutes for the interruption period is set based on the need for message information. Such notification of message information is effective if it is performed before the user returns home from outside. Therefore, it is preferable to notify when the message notification is interrupted for up to about 120 minutes when the effect of the message notification can be expected.

[Third Embodiment]

The information request section is built in the terminal control section 31 of the communication terminal 30 .

The information notification unit 24 performs message notification based on the detection information of the air purifier 10 belonging to the installation location. As in the example of FIG. 8, when two air purifiers 10 are registered at the installation location, message notification is performed based on the detection information of the two units. If the detection information of two air purifiers 10 is the same and the content of the message information to be notified is the same, the notification of the message information is narrowed down to one for one unit. For example, the status of the air purifier 10 at the top of the list is notified. Although not specifically mentioned in the above-described first and second embodiments, the same applies when a plurality of air purifiers 10 are installed in the user's home 41 and registered in the server 20 .

As another example, as shown in FIG. 9, an abnormality confirmation button 50 requesting notification of message information may be arranged above the list representing the air purifiers 10 on the home screen. In the list representing the air purifier 10, an abnormality confirmation button 50 and a power button 51 for starting/stopping the operation of the air purifier 10 are displayed. Touching (selecting) a portion other than these buttons in the list causes a transition to the aforementioned operation screen (see FIG. 7). When the power button 51 on the list is pressed, the operation can be started/stopped without transitioning to the operation screen.

In the first to third embodiments described above, the configuration in which the information notification unit 24 is provided in the server 20 was exemplified. Further, the information notification unit 24 may be provided separately for a plurality of servers, or may be provided separately for the server 20 and the communication terminal 30 or the air cleaner 10 . In other words, the function of estimating and the function of notifying message information according to the estimation may be installed in separate devices.
