  The present invention relates to a notification system including an air cleaner, and an air cleaner.

  2. Description of the Related Art In recent years, a technology that allows home appliances (household electronic devices) to be connected to a communication network and can be remotely operated and confirmed the operation status of home appliances from a communication terminal device such as a tablet terminal or a smartphone even from outside the home has become widespread. For example, Patent Literature 1 discloses a security management device that notifies a user's mobile terminal of the operation status of an electric lock on a door or window at home or the operation status of a home appliance via a communication network. Further, in this apparatus, the notification destination of the operation status can be a security company.

JP 2005-031984 (released February 3, 2005)

  Here, in the security management device disclosed in the cited document 1, it is necessary to newly attach a camera in order to monitor or watch the situation in the building. However, there are some users who have resistance to the introduction of cameras. In addition, the cost of the camera is excessive. Here, for example, as a watching system for watching a person, there is a system for notifying the outside of the operation of the home appliance by the watching target, but there is also a watching target that the operation is troublesome because the operation to the home appliance is required. .

  Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide a notification system that can perform watching or security management at a low cost without bothering the user.

  In order to solve the above problems, the present inventors have intensively studied and found that sensors such as a dust sensor and an odor sensor provided in an air cleaner can be effectively used, and have completed the present invention. There has never been an idea of using an air cleaner for watching a person or for security management (crime prevention).

  Therefore, the notification system according to one aspect of the present invention includes an air cleaner having a sensor unit that senses the environment of a space where the device is installed in order to control the air cleaning operation, and a result obtained by sensing the sensor unit. A determination unit that determines the presence or absence of movement of a person in the space and a notification unit that notifies an external device of information corresponding to a determination result by the determination unit.

  According to the said structure, since the sensor part senses the surrounding environment in order to perform air cleaning operation | movement, it is originally provided in the air cleaner. Moreover, although the sensing result by a sensor part changes with a motion of a person, it has nothing to do with operation which a user performs with respect to an air cleaner. That is, the movement of a person can be sensed indirectly by the sensor unit of the air cleaner. Also, according to the above configuration, the external device is notified of information corresponding to the determination result of the presence or absence of human movement, so that the user of the external device can immediately confirm the information.

  Therefore, according to the above configuration, watching or security management can be performed at low cost without bothering the user.

The air cleaner 10 performs an air cleaning operation so that the dust detection level is below a certain level. In addition, the air cleaner 10 performs an air cleaning operation in a weak operation when the detection level of illuminance is below a certain level (dark). As described above, the environment sensed by the odor sensor, the dust sensor, and the illuminance sensor is necessary for the air cleaner 10 to control the air cleaning operation. The odor sensor may be a sensor that senses not only odor but also gas. The dust sensor may be a sensor that senses not only dust but also fine particles such as pollen and PM2.5.

  Further, the sensor unit 14 includes a sensor for sensing the amount of water stored in the water tank 17 and a sensor for sensing clogging of the filter 18. You may have sensors other than these. The clogging of the filter 18 can be detected from changes in air volume and pressure, light transmittance of the filter 18 and the like.

(Management server device)
The management server device 20 is a server that manages the air purifier 10. There may be one management server device 20 or a plurality of servers. As illustrated in FIG. 2, the management server device 20 includes a control unit 21, a storage unit 22, and a communication unit 23. The control unit 21 is a block that includes, for example, a computer device including an arithmetic processing unit such as a CPU or a dedicated processor, and controls the operation of each unit of the management server device 20. In addition, the control unit 21 has a function as the determination unit 24.

  The determination unit 24 is a block that determines whether or not there is a person's movement in the user's home 50 in which the air cleaner 10 is installed, based on a sensing result by the sensor unit 14 of the air cleaner 1. If the sensing result is above a certain level or if there is a change in the sensing result, it is determined that there is human movement. If the sensing result is below a certain level or if there is no change in the sensing result, it is determined that there is no human movement. Specifically, how to determine which sensing result is used will be described later.

  The storage unit 22 is a block that stores various information (data) used in the management server device 20. Further, the storage unit 22 stores the operation status of the air cleaner 10 received from the air cleaner 10. Moreover, the air cleaner 10 and the communication terminal device 30 are managed in association (linked). A plurality of air cleaners 10 and one communication terminal device 30 may be managed in association with each other, a single air cleaner 10 and a plurality of communication terminal devices 30 may be managed in association with each other, A plurality of air cleaners 10 and a plurality of communication terminal devices 30 may be managed in association with each other.

  The communication unit 23 is a block that performs communication via the communication network 60. The communication unit 23 communicates with the air cleaner 10 via the communication network 60. In addition, communication with the communication terminal device 30 is performed.

  The communication unit 23 receives the operation status from the air cleaner 1. The operation status includes information on which mode is set. Further, the communication unit 23 receives a sensing result from the sensor unit 14. In addition, the communication unit 23 transmits (notifies) information corresponding to the determination result of the presence or absence of human movement by the determination unit 24 to the communication terminal device 30. Note that, when the management server device 20 manages a plurality of air purifiers 10 associated with a certain communication terminal device 30, the identification information of the air purifier 10 is also transmitted.

  In addition, the communication unit 23 may notify the server device 70 of the security company with which the user of the user home 50 has contracted information according to the determination result of the presence or absence of human movement by the determination unit 24. In this case, it can be used as a judgment material for the service person of the security company to be dispatched to the user home 50.

  When the air purifier 10 is set to the watching mode, the communication unit 23 notifies the information according to the determination result when the determination unit 24 determines that there is no human movement. That is, when there is no movement of a person, the watching target may fall down. When the air cleaner 10 is set to the watching mode, when the determination unit 24 determines that there is a person's movement, the notification may not be performed, but may be performed. This is because the communication terminal device 30 can confirm the safety of the monitoring target by performing the notification.

  Further, when the air purifier 10 is set to the security mode, the communication unit 23 notifies the information according to the determination result when the determination unit 24 determines that there is a person's movement. That is, when there is a person's movement, a suspicious person may have entered the user's home 50. When the air cleaner 10 is set to the security mode, the notification may not be performed when it is determined that there is no human movement.

  Here, the information according to the determination result may be the determination result itself that there is a person's movement when the air cleaner 10 is set to the security mode, or there is a suspicious person (possible For example), information for calling attention, or the like. In addition, when the air cleaner 10 is set to the watching mode, the determination result itself that there is no movement of the person may be used, information that the watching target has fallen (possibly), It may be information that calls attention. It is not limited to these.

(Communication terminal device)
The communication terminal device 30 is a communication device and is connected to the management server device 20 via the communication network 60. As the communication terminal device 30, a general-purpose device such as a smartphone or a tablet terminal is assumed.

  As illustrated in FIG. 3, the communication terminal device 30 includes a control unit 31 that controls the operation of each unit of the communication terminal device 30, a storage unit 32 that stores various types of information, and a display operation unit 33 that displays various types of information and accepts various types of operations. , And a communication unit 34 that performs communication via the communication network 60.

  In the communication terminal device 30, when the communication unit 34 receives information from the management server device 20 according to the determination result of the presence or absence of human movement at the user home 50 in which the air purifier 10 is installed, the display operation unit 33 receives the information. Display that information. In addition, voice notification may be performed. Therefore, the user can check the presence / absence of a person's movement at the user's home 50 using the communication terminal device 30. Such information display and voice notification can be performed by an application. By devising how to display the application, it becomes possible to play a role in crime prevention measures.

  In the present embodiment, communication between the communication terminal device 30 and the air purifier 10 is performed via the management server device 20, but may be directly performed.

  Further, the air cleaner 10 may be configured to be remotely operated from the communication terminal device 30. A known technique can be used for the configuration for remotely operating the air cleaner 10 from the communication terminal device 30.

(Judgment and notification)
The determination of the determination unit 24 and the notification of the communication unit 34 will be described with reference to FIG.

  First, the case where the air cleaner 10 is set to the security mode will be described. As shown in FIG. 5, in the day and night time zones, when the dust level sensed by the dust sensor of the sensor unit 14 is a certain level or higher, or the dust level sensed by the dust sensor is low to high. When it is changed, the determination unit 24 determines that there is a human movement. Then, the communication unit 23 notifies the communication terminal device 30 of information corresponding to the determination result that there is a person's movement. The same applies when the determination is made from the sensing result of the odor sensor of the sensor unit 14.

  Also, in the day and night time zones, when the level of illuminance sensed by the illuminance sensor of the sensor unit 14 changes (changes from a dark state to a bright state), the determination unit 24 determines that there is a person's movement. Then, the communication unit 23 notifies the communication terminal device 30 of information corresponding to the determination result that there is a person's movement.

  Next, the case where the air cleaner 10 is set to the watching mode will be described. As shown in FIG. 5, in the night time zone, when the dust level sensed by the dust sensor of the sensor unit 14 has not changed for a long time, the determination unit 24 determines that there is no human movement. It is determined that this is not a problem, and the communication unit 23 does not notify. The same applies when the determination is made from the sensing result of the odor sensor of the sensor unit 14. The same applies to the determination from the sensing result of the illuminance sensor of the sensor unit 14.

  On the other hand, in the daytime period, if the dust level sensed by the dust sensor of the sensor unit 14 has not changed for a long time, or even if the watched time has passed (the time can be set from the operation unit 15). Yes) If there is no change in the dust level sensed by the dust sensor, the determination unit 24 determines that there is no human movement. Then, the communication unit 23 notifies the communication terminal device 30 of information corresponding to the determination result that there is no human movement. The same applies to the determination based on the sensing result information by the odor sensor of the sensor unit 14.

  Also, in the daytime period, when the illuminance level sensed by the illuminance sensor of the sensor unit 14 does not change (still in a dark state), the determination unit 24 determines that there is no human movement. Then, the communication unit 23 notifies the communication terminal device 30 of information corresponding to the determination result that there is no human movement.

  In the above description, when the air cleaner 10 is set to the watching mode, information indicating that there is a person's movement is not notified. This is because notification is not performed when there is a person's movement, and only when there is no person's movement, there is no need to notify a lot of information, and there is no movement of the person in the communication terminal device 30. This is because it is possible to strongly recognize an emergency situation by receiving a notification only in an emergency situation (whether the watch target has fallen). However, information indicating that there is a person's movement may be notified. This is because the communication terminal device 30 can confirm the safety of the monitoring target by performing the notification.

  In addition, it is preferable that the case where the air cleaner 10 is set to the security mode is configured to perform the determination more severely than the case where the air cleaner 10 is set to the watching mode.

(Process after notification)
In the notification system 100, after the determination unit 24 transmits information according to the determination result of the presence or absence of human movement to the communication terminal device 30, the voice output unit 19 of the air purifier 10 according to an instruction from the communication terminal device 30. To output a predetermined sound. Further, instead of an instruction from the communication terminal device 30, the management server device 20 instructs the air cleaner 10 to output a predetermined sound from the sound output unit 19 according to the determination result by the determination unit 24. Also good.

  The predetermined sound output from the sound output unit 19 is preferably a sound for making an inquiry to the watching target, such as “OK?” When the watching mode is set. When the security mode is set, for example, a threatening voice such as “Is there anyone?” Is preferable. Furthermore, the air cleaner 10 may be provided with a lamp or the like so as to warn by flashing quickly.

  By outputting the predetermined sound in this way, it is possible to increase the effect of watching or security management.

  Further, in the notification system 100, the air cleaner 10 receives a response to the predetermined sound at the operation unit 15, transmits the received response to the management server device 20, and the management server device 20 receives the response from the communication unit 23. Information corresponding to the accepted response is notified to the communication terminal device 30. The response is a predetermined operation on the operation unit 15. For example, a specific button is provided on the operation unit 15 and a response is accepted when the button is pressed down. Alternatively, a voice input unit may be provided in the operation unit 15 and a voice response may be received. In this case, the management server device 20 performs voice recognition.

  Moreover, when the watching target has a communication terminal device and the communication terminal device is also managed in association with the air purifier 10, the communication terminal device may be able to respond.

  When the air cleaner 10 is set to the watching mode, when information corresponding to the response is notified in the communication terminal device 30, the user of the communication terminal device 30 confirms this, thereby The user can confirm the safety of the watching target.

  In addition, when the air cleaner 10 is set to the security mode, for example, there is an incorrect operation (for example, an incorrect button is pressed) as information corresponding to the response in the communication terminal device 30. If the information indicating that the response has not been received within a predetermined time is notified, the user of the communication terminal device 30 confirms this and determines that there may be an intrusion of the user's home 50 suspicious person. For example, you can contact a security company.

(Concrete example)
As a specific example using the notification system 100 including the air purifier 10 and the management server device 20, four people (users a to d) live in the user home 50, and the users a to d are the communication terminal devices 30 a to 30 d, respectively. A case where the communication terminal device 30a is attached to the air purifier 10 will be described.

  Assume that the air cleaner 10 is set to the security mode, and after the user a goes out, the user a is not sure whether the remaining three (users b to d) are in the user home 50. In this case, when the communication terminal device 30a receives a notification from the management server device 20 that there is a person's movement, the user a receives the remaining three communication terminal devices 30b to 30d and the air purifier from the communication terminal device 30a. Confirmation information for confirmation is transmitted to the machine 10 to prompt a reply.

  The users b to d of the communication terminal devices 30b to 30d that have received the confirmation information return to the communication terminal device 30a whether or not they are at home. On the other hand, the air cleaner 10 that has received the confirmation information outputs a voice message “please press the A button” from the voice output unit 19. Here, it is assumed that the A button is a button provided on the operation unit 15. When the A button is pressed, the information is sent from the air cleaner 10 to the communication terminal device 30a via the management server device 20, so that the communication terminal device 30a is informed that there is a resident in the user home 50. Can be confirmed. If the A button is not pressed, the communication terminal device 30a notifies the communication terminal device 30a of the information via the management server device 20 to indicate that there is a suspicious person in the user home 50. This can be confirmed by the device 30a.

  In addition, by setting the A button as a key that only the users a to d know (push order) in advance, the suspicious person can not cope with the voice. Such a configuration is more preferable for crime prevention. Of course, it is necessary to assume the situation when there are pets.

  In the above, the case where only the communication terminal device 30a is tied to the air cleaner 10 has been described. However, in the case where all of the communication terminal devices 30a to 30d are tied to the air cleaner 10, It becomes processing. In this case, all the communication terminal devices 30a to 30d associated with each other receive information (sensor reaction information) that there is a human movement. The communication terminal device that first transmits the confirmation information to the management server device 20 among the communication terminal devices 30a to 30d becomes the main terminal device, and waits for a reply from another communication terminal device. In this state, the other terminal devices cannot transmit the confirmation information, and are configured to be able to reply only to the received confirmation information and confirm (monitor) the state of the air purifier 10. With such a configuration, the air cleaner 10 receives only one confirmation information, and the sound output is also performed once.

  Further, when the A button is not pressed within a predetermined period or when the wrong button is pressed, the air purifier 10 may output a threatening predetermined sound from the sound output unit 19. Furthermore, if the air purifier 10 is configured such that the lamp blinks, the threatening predetermined sound does not stop, or recording or recording starts, security can be further enhanced.

(Effects of notification system)
As described above, in the notification system 100, the determination unit 24 determines the presence / absence of a human movement from the sensing result of the sensor unit 14. Since the sensor unit 14 senses the surrounding environment in order to control the air cleaning operation, it is originally provided in the air cleaner 10. Moreover, although the sensing result by the sensor part 14 changes with a person's movement, it is unrelated to the operation which a user performs with respect to the air cleaner 10. FIG. That is, the movement of a person can be indirectly sensed by the sensor unit 14 of the air cleaner 10. Further, according to the notification system 100, the communication terminal apparatus 30 is notified of the information immediately according to the communication terminal apparatus 30 in order to notify the communication terminal apparatus 30 of information corresponding to the determination result of the presence or absence of human movement. be able to.

  When the notification system 100 is used for watching, when the air purifier 10 is set to the watching mode and information indicating that there is no movement of the person being watched is notified, the occurrence of an abnormal situation is grasped by the external device. it can. When the notification system is used for security management (crime prevention), when information indicating that there is a person's movement is notified, the occurrence of an abnormal situation can be grasped by the external device.

  Here, when a person is moving, odors and dust are generated, and when a person is moving, a curtain is opened or a light is turned on to brighten the room. That is, the sensing results from the odor sensor, dust sensor, and illuminance sensor are closely related to human movement. Therefore, according to the notification system 100, it is possible to accurately determine the presence or absence of human movement.

  Moreover, in the notification system 100, since the air cleaner 10 has a watching mode and a security mode, the notification system 100 can perform monitoring of a person and security management when there is no person.

  Moreover, in the notification system 100, since the air cleaner 10 outputs a predetermined sound according to the determination result of the presence / absence of human movement by the determination unit 24 or according to an instruction from the communication terminal device 30, the watch system 10 Or the effect of security management can be improved.

  Further, in the notification system 100, information corresponding to the response to the predetermined voice can be notified to the communication terminal device 30, so that the communication terminal device 30 can check the information corresponding to the response. The response may be, for example, an operation of the operation unit 15 of the air cleaner 10 or an audio response. When the notification system 100 is used for watching, it is convenient to use if it is configured to be able to respond easily. Further, when the notification system 100 is used for security management, if the notification system 100 is configured so that a predetermined voice does not stop or recording or recording starts unless a complex response is made, security is further enhanced. it can.

  In the above description, the determination and notification using the sensing results from the dust sensor, the odor sensor, and the illuminance sensor have been described. However, for example, when the air cleaner 10 is set to the watching mode and the operation unit 15 of the air cleaner 10 has not been operated for a long time, it may be determined that there is no human movement and notification may be given. Or when the air cleaner 10 is set to security mode and the operation part 15 of the air cleaner 10 is operated, you may determine that there exists a person's movement and may notify. In addition, when the watch mode is set, there is no change in the amount of water stored in the water tank 17 of the air purifier 10 or a notification (display) that prompts the user to replace the filter 18 on a display unit (not shown). However, when the exchange is not performed, it may be determined that there is no movement of the person and notification may be given. In addition, notification may be performed when the value sensed by the temperature sensor or the humidity sensor is an abnormal value as a level at which a person lives.

  In the above description, the presence / absence of human movement based on the sensing result is determined for each sensor of the sensor unit 14, but the presence / absence of human movement is determined by combining the sensing results of the plurality of sensors. Also good. By performing the determination in combination, it is possible to perform a highly accurate determination.

[Embodiment 3]
Still another embodiment of the present invention will be described below. For convenience of explanation, members having the same functions as those described in the first or second embodiment are denoted by the same reference numerals and description thereof is omitted.

  In the present embodiment, in the notification system 100 according to the first embodiment or the notification system 100A according to the second embodiment, the determination unit 24 changes the determination reference according to the time zone.

  For example, people's movements often change according to the time of day, such as going to bed in the middle of the night, and eating in a certain time in the morning, some time in the day, and some time in the night. . Therefore, the determination part 24 can raise the precision of determination by changing the determination reference | standard of the presence or absence of a person's movement according to a time slot | zone.

  For example, when the air cleaner 10 is set to the security mode, it is considered to change the determination criterion for the presence or absence of human movement between the day and night. As shown in FIG. 5, since it is assumed that the user is sleeping at night, that is, it is assumed that the user is in the user's house 50, it is considered that there is some movement of the person. If this is sensed and notified, it will be annoying to the user. On the other hand, in the daytime, it is assumed that the user is away, and security needs to be strengthened. In view of these, the night detection level (determination criterion) of each sensor is set higher than the day detection level, and based on this, the determination unit 24 determines the presence or absence of human movement.

  Further, when the air purifier 10 is set to the watching mode, it is considered that the determination criterion for the presence or absence of human movement is changed between a meal time zone and other time zones. That is, since it is considered that the odor increases during the meal time zone, the detection level of the odor sensor during the meal time zone may be set high. If any sensor is set to a high detection level, it will not be detected by a small change. In other words, since the reference (threshold value) for determining that the detection has been increased, it is difficult for the sensor to detect.

  The determination criteria according to the time zone may be changed, specifically, the detection level of each sensor may be set by the user from the air cleaner 10 or the communication terminal device 30.
