・Embodiment 1
FIG. 1 is a diagram schematically showing an air conditioning system 5 having an air conditioner 100. As shown in FIG.
The air conditioning system 5 includes an air conditioner 100 , a sensor information storage unit 4 and a sensor information generation device 6 . The sensor information generation device 6 includes an activity meter 6a and/or a HEMS (Home Energy Management System) 6b.

For example, as shown in Table 1, the activity meter 6a provides the user with activity information indicating the activity state of the user, such as the number of steps per unit time, heart rate, and/or energy consumption of the user. It is generated in association with user identification information for identification. Table 1 shows an example of activity information indicating user's activity status.

For example, as shown in Table 2, the HEMS 6b includes user identification information for identifying a user, space identification information for identifying an air-conditioned space such as the user's home (for example, living room, bedroom, etc.), Information including electronic device identification information for identifying electronic devices (e.g., televisions, electromagnetic cookers, etc.) placed in the air-conditioned space, and the operating status of the electronic devices (operating, non-operating), etc. The information is stored in the sensor information storage unit 4 as activity information indicating the activity state of the user. The operating status of the electronic device may be determined based on a well-known technique, such as the presence or absence of power supply to the electronic device and/or the amount of power supplied per unit time. In addition, the electronic device identification information of the electronic device may be registered in association with, for example, a power tap connected to the outlet of the electronic device, the amount of power supplied to the electronic device per unit time, and/or It may be registered in association with the waveform of the power supplied to the electronic device when it rises. Table 2 shows an example of activity information indicating the activity status of the user.

The sensor information generation device 6 stores the generated activity information in the sensor information storage unit 4 via a network (not shown).

The sensor information storage unit 4 is a storage area provided on the network 3 and stores activity information. Here, the air conditioning system 5 may have two or more sensor information storage units 4 . The sensor information storage unit 4 may be individually provided by a plurality of businesses such as, for example, a business that provides the air conditioning system 5, a business that provides the activity meter 6a, and a business that provides the HEMS 6b. good.

The air conditioner 100 is a device that conditions air in a room, which is a space to be air-conditioned, for cooling, heating, dehumidification, and the like. An air conditioner 100 includes an indoor unit 1 and an outdoor unit 2 .

The indoor unit 1 is installed in the air-conditioned space. The indoor unit 1 conditions the air in the air-conditioned space by, for example, blowing out temperature- and/or humidity-adjusted air into the air-conditioned space.

The indoor unit 1 includes a memory 12, a processor 13, an air blower 14, a detector 15, a storage 16, a communication interface 11, an input/output interface 17, and an operation unit 18.

The operation unit 18 is, for example, a remote controller, and receives user's desired operations such as starting operation, stopping operation, setting a target temperature, and setting a target humidity.

The detection unit 15 has, for example, a sensor that detects the temperature and/or humidity of the air-conditioned space. The blower unit 14 has a blower fan provided inside the housing of the indoor unit 1 and a blower motor. The blower unit 14 rotates a blower fan with a blower motor to generate an airflow that blows into the air-conditioned space.

The processor 13 is, for example, a CPU (Central Processing Unit), processes input data, and outputs the processing results. The memory 12 is, for example, a DRAM (Dynamic Random Access Memory) functioning as a main memory. The memory 12 temporarily stores programs executed by the processor 13, for example. Memory 12 and processor 13 may be configured as one processing circuit. The storage unit 16 is, for example, an SSD (Solid State Drive) that stores data as an auxiliary storage device. The storage unit 16 stores data used in the processing of the processor 13, for example.

The communication interface 11 is, for example, a LAN adapter or a wireless LAN transceiver. The communication interface 11 connects to the sensor information storage unit 4 via the network 3 .

The input/output interface 17 is connected to the outdoor unit 2 installed outdoors via a communication cable (not shown).

FIG. 2 is a diagram schematically showing functions of the indoor unit 1. As shown in FIG.
The processor 13 of the indoor unit 1 implements the functions of an acquisition unit 131 , a determination unit 132 , and a control unit 133 by executing programs read from the memory 12 .

The acquisition unit 131 acquires the activity information indicating the user's activity state stored in the sensor information storage unit 4 as sensor information via the communication interface 11 .

The determination unit 132 determines whether the user's activity state is active or inactive based on the sensor information acquired by the acquisition unit 131 . Here, when the sensor information acquired by the acquisition unit 131 is the activity information generated by the activity meter 6a, the determination unit 132 determines each item included in the sensor information and the determination stored in the storage unit 16. By comparing with the threshold corresponding to each item defined in the table 132b (Table 3), it is determined whether the user's activity state is "active" or "inactive". Table 3 shows information set in the determination table 132b.

For example, when the number of steps of user A (4000 steps in Table 1) is equal to or greater than the threshold value for the number of steps (1000 steps in Table 3), the determination unit 132 determines that user A is active. Similarly, for example, when the number of steps of user B (500 steps in Table 1) is less than the threshold (1000 steps in Table 3), the determination unit 132 determines that the activity state of user B is "inactive". do. Here, although the determination unit 132 determines the user's activity state based on the number of steps, the user's activity state is determined by comparing the heart rate and the threshold, or the energy consumption and the threshold. is "active" or "inactive". In addition, the determination unit 132 does not make a determination based on only one result of comparing the activity information and the threshold value, but uses the larger number of "active" and "non-active" among a plurality of results. It may be determined that the person is active. The threshold may be set to different values depending on the user's age, sex, height, and/or weight, or may be set to any value by the user. Further, when the activity meter 6a can determine the user's sleep, the determination unit 132 determines "inactive" or "active" based on the determination result of the activity meter 6a instead of comparison with the threshold value. Also good.

Further, when the sensor information acquired by the acquisition unit 131 is the activity information generated by the HEMS 6b, the determination unit 132 uses the operation information of the electronic device included in the sensor information and the determination table stored in the storage unit 16 as 132b (Table 4) to determine whether the user's activity status is "active" or "inactive". Table 4 shows information set in the determination table 132b. The determination table 132b is set to determine that the user is active when the electromagnetic cooker is in operation. Further, the determination table 132b is set to determine that the user is inactive when the television is in operation.

For example, when the electromagnetic cooker installed in the kitchen of user B is in operation in Table 2, the determination unit 132 determines that the activity state of user B, who is presumed to be cooking, is "active". Similarly, for example, when user C's television is in operation, the determination unit 132 determines the activity state of user C, who is estimated to be watching (resting), to be "inactive". Here, when a plurality of electronic devices are present in one air-conditioned space, the order of priority may be determined in advance as to which electronic device is associated with a condition for determining that it is active. For example, even if the television of user C is in operation, if the television game machine used by connecting to the television is in operation, the determining unit 132 determines that the activity state of user C is presumed to be playing a game. may be determined as "active". The conditions set in the determination table 132b for determining that the user is active may be set to arbitrary values by the user.

By the way, the acquisition unit 131 may acquire both the activity information generated by the activity meter 6a and the activity information generated by the HEMS 6b as sensor information within a predetermined unit time. Then, if the determination result based on the activity information generated by the activity meter 6a (for example, active) is the same as the determination result based on the activity information generated by the HEMS 6b (for example, active), the determination unit 132 , the determination result is regarded as the activity state of the user. On the other hand, when the determination result based on the activity information generated by the activity meter 6a (for example, active) and the determination result based on the activity information generated by the HEMS 6b (for example, inactive) are different, the determination unit 132 considers the activity status of the user to be "active". In this way, priority is not given to either the determination result based on the activity information generated by the activity meter 6a or the determination result based on the activity information generated by the HEMS 6b. By giving priority to the fact that the inside is indicated, it is possible to prevent the comfort of the user from being impaired.

When the determination unit 132 determines that the user's activity state is "inactive", the control unit 133 makes the air volume of the blower unit 14 weaker than when the user's activity state is determined as "active". Control information for controlling the air blower 14 is output to the air blower 14 . Further, when the determination unit 132 determines that the user's activity state is “active”, the control unit 133 outputs to the blower unit 14 control information for controlling the air volume of the automatic operation mode.

FIG. 3 is a diagram showing the determination result of the determination unit and the air volume of the blower unit.
As shown in the figure, when the determination unit 132 determines that the user's activity state is "inactive," the control unit 133 is more sensitive than when the user's activity state is determined to be "active." , the air volume of the air blower 14 is controlled to be weak. By controlling the air volume of the blower 14 in this way, the control unit 133 can reduce the unpleasant feeling that the rotating sound of the blower fan of the blower 14 gives to the user.

In addition, when the determination unit 132 determines that the user's activity state is "active", the control unit 133 controls the air volume to the automatic operation mode. Here, when the indoor temperature and the target set temperature are different, the control unit 133 controls the air volume of the blower unit 14 to be stronger than when the user's activity state indicates inactivity. to control. In this way, the control unit 133 controls the air volume of the blower unit 14, thereby suppressing deterioration of comfort for the user who desires harmony between the indoor temperature and the target set temperature.

FIG. 4 is a flow chart showing the processing of the air conditioner.
The acquisition unit 131 acquires activity information indicating the activity state of the user as sensor information (step S100). The determination unit 132 determines whether the activity state of the user is active or inactive based on the sensor information acquired by the acquisition unit 131 (step S101). When the activity state of the user indicates that the user is active (S101: YES), the control unit 133 controls the blower unit 14 so as to achieve the air volume of the automatic operation mode (S102). On the other hand, when the user's activity state indicates that the user is inactive (S101: NO), the control unit 133 makes the wind volume in the silent mode, that is, the user's activity state, weaker than when it is determined to be "active." The air volume of the air blower 14 is controlled as follows (S103).

As described above, when the user's activity state indicates that the user is inactive, the control unit 133 of the air conditioner 100 determines that the user's activity state is "active". control to weaken As a result, the air conditioner 100 can reduce discomfort given to the user by the rotating sound of the blower fan. Further, when the determination unit 132 determines that the user's activity state is "active", the control unit 133 controls the air volume to be in the automatic operation mode. That is, when the indoor temperature and the target set temperature are different, the control unit 133 sets the air volume in the automatic operation mode to be higher than when the user's activity state indicates that the user is inactive. control so that the air volume of is strong. In this way, the control unit 133 controls the air volume of the blower unit 14, thereby suppressing deterioration of comfort for the user who desires harmony between the indoor temperature and the target set temperature.

・Embodiment 2
When the user returns home or moves from one air-conditioned space to another in the home, the user's comfort may be impaired due to the difference between the room temperature and the target set temperature. Therefore, in the second embodiment, based on not only the user's activity status but also the user's room presence history in the air-conditioned space and/or room presence information indicating the user's presence schedule, the presence of the air-conditioned space is determined. The room condition is determined, and the air conditioning in the air-conditioned space is controlled based on the determination result.

FIG. 5 is a diagram schematically showing the air conditioning system 5 having the air conditioner 100. As shown in FIG.
The air conditioning system 5 includes an air conditioner 100 , a sensor information storage unit 4 and a sensor information generation device 6 . The sensor information generation device 6 has an activity meter 6a and/or a HEMS 6b. The activity meter 6a and the HEMS 6b generate activity information used to determine the user's activity status, as in the first embodiment. Moreover, the sensor information generation device 6 has a HEMS 6b, a scheduler 6c, and/or a positioning device 6d. The HEMS 6b, the scheduler 6c, and the positioning device 6d generate occupancy information used to determine whether or not the user is in the air-conditioned space (hereinafter referred to as occupancy status).

The HEMS 6b includes user identification information for identifying a user, space identification information for identifying an air-conditioned space such as the user's home (e.g., living room, bedroom, etc.), and electronic equipment placed in the air-conditioned space. (e.g., television, electromagnetic cooker, etc.), and information including the operating status of the electronic device (operating, non-operating) to determine the user's room presence status is stored in the sensor information storage unit 4 as room occupancy information used for this purpose.

The scheduler 6c stores the user's schedule information in the sensor information storage unit 4 as room presence information used to determine the user's presence in the room. The schedule information includes, for example, a history of past occupancy in the air-conditioned space and/or information indicating a future occupancy schedule. In addition, the schedule information includes information such as the start date and time of being in the air-conditioned space, the end date and time of being in the air-conditioned space, and the air-conditioned space. include. The scheduler 6c accepts data input of user's schedule information via an operation unit (not shown), but the acquisition method and data format do not matter.

The positioning device 6d is, for example, a mobile terminal possessed by a user, and stores position information generated by measuring the position of its own terminal as sensor information used to determine the user's presence in the room. Store in part 4. The sensor information storage unit 4 stores the transition (movement history) of the user's position information from the past to the present.

The acquisition unit 131 acquires the room presence information stored in the sensor information storage unit 4 as sensor information. Based on the sensor information acquired by the acquisition unit 131, the determination unit 132 determines whether the user is “in the room” or “not in the room” in the air-conditioned space. In addition, when the user is "not present" in the air-conditioned space, the determining unit 132 determines the expected time of being in the room when the user is "present" in the air-conditioned space.

When determining the expected time of being in the air-conditioned space based on the room presence information generated by the HEMS 6b, the determination unit 132 switches the operation status (operating or non-operating) of the electronic device included in the room presence information. The estimated time of stay in the air-conditioned space is determined from the statistical value of the time.

For example, as shown in Table 5, the statistical value of the time when the operating status of the lighting (electronic device) installed in the living room (air-conditioned space) switches from "non-operating" to "operating" is 17:00. In this case, the determination unit 132 determines that the expected time of being in the air-conditioned space is 17:00.

Further, for example, as shown in Table 6, the statistical value of the time when the operating status of the security terminal (electronic device) installed in the living room (air-conditioned space) switches from "operating" to "not operating" is 17: If it is 00, the determination unit 132 determines that the expected time of being in the living room (air-conditioned space) is 17:00.

When determining the expected time of being in the air-conditioned space based on the room occupancy information generated by the scheduler 6c, the determination unit 132 indicates the past occupancy history of the air-conditioned space and/or the future occupancy schedule. The expected time of occupancy in the air-conditioned space is determined from the statistical value of the start time of occupancy included in the information.

For example, as shown in Table 7, when the statistical value of the start time of stay in the living room (air-conditioned space) included in the past stay history is 17:00, the determining unit 132 The scheduled room time is determined to be 17:00.

When determining the expected time of being in the air-conditioned space based on the position information generated by the positioning device 6d, the determination unit 132 determines the air-conditioned space from the statistical value of the time when the user's position information indicates the air-conditioned space. Determine the expected time of being in the room.

For example, as shown in Table 8, when the statistical value of the time at which the user's position information indicates the air-conditioned space (home) is 17:00, the determining unit 132 determines the expected time of being in the air-conditioned space. Determined as 17:00.

By the way, the room presence information generated by the HEMS 6b acquired as sensor information, the room presence information generated by the scheduler 6c, and the room presence information generated by the positioning device 6d may differ from each other. In this case, the determination unit 132 determines whether the room presence information generated by any one of the room presence information generated by the HEMS 6b, the scheduler 6c, and the positioning device 6d is combined with the room presence information generated by the other device. may take precedence over information.

The control unit 133 controls the air volume of the blower unit 14 so that the difference between the indoor temperature of the air-conditioned space and the target set temperature is less than a threshold value by the expected time of occupancy in the air-conditioned space determined by the determination unit 132. Control information is output to the blower unit 14 .

FIG. 6 is a diagram showing the determination result of the determination unit, the air volume of the blower unit, and the temperature of the air-conditioned space.
If the temperature Te3 of the air-conditioned space is higher than the threshold temperature Te2 and the user is not in the room at the time Ti1 that is a predetermined time β before the expected room presence time Ti2 determined by the determination unit 132, The control unit 133 sets the air volume (automatic operation mode air volume) to the air blowing unit 14 so that the difference between the temperature of the air-conditioned space and the set temperature Te1 is less than the threshold Te2 by the scheduled occupancy time Ti2.

In addition, the control unit 133 sets the air volume to the automatic operation mode when the determining unit 132 determines that the user's activity state is "active" even if it is later than the expected time Ti2 of being in the room. Such an air volume (air volume in the automatic operation mode) is set in the air blower 14 .

Then, when the determination unit 132 determines that the user's activity state is "inactive", the control unit 133 determines that the air volume of the blower unit 14 is higher than when the user's activity state is determined to be "active". A weakened air volume is set in the air blower 14.例文帳に追加

By controlling the air volume of the blower unit 14 in this way, the control unit 133 can prevent the comfort of the user who desires harmony between the room temperature and the target set temperature from being impaired. In addition, by controlling the air volume of the blower 14 in this manner, the control unit 133 can reduce the unpleasant feeling that the rotating sound of the blower fan of the blower 14 gives to the user.　

FIG. 7 is a flow chart showing the processing of the indoor unit 1. As shown in FIG.
The acquisition unit 131 acquires the room presence information stored in the sensor information storage unit 4 as sensor information (step S104).

The determination unit 132 determines whether the user is "in the room" or "not in the room" in the air-conditioned space based on the sensor information acquired by the acquisition unit 131 (step S105).

If it is determined that the user is “not in the room” in step S105 (step S105; NO), the determination unit 132 determines that the user is “not in the room” in the air-conditioned space based on the sensor information acquired by the acquisition unit 131. ” is calculated (step S106).

At a time Ti1 that is a predetermined time β before the expected time of occupancy Ti2 determined by the determination unit 132 (step S107: YES), the control unit 133 adjusts the temperature of the air-conditioned space to the set temperature by the expected time of occupancy Ti2. An air volume (air volume in the automatic operation mode) that makes the difference in Te1 less than the threshold α is set in the air blower 14 (step S108).

Based on the sensor information acquired by the acquisition unit 131, the determination unit 132 determines that the user is “in the room” in the air-conditioned space (step S105; YES), the activity indicating the activity state of the user. Information is acquired as sensor information (step S100). Since subsequent processing is the same as that of Embodiment 1, explanation is omitted.

As described above, in the second embodiment, the air conditioner 100 stores not only the user's activity status, but also the room presence information indicating the user's room presence history in the air-conditioned space and/or the room presence schedule. Based on this, the occupancy status of the air-conditioned space is determined, and the air in the air-conditioned space is conditioned based on the determination result. As a result, when the air conditioner 100 returns home or moves from one air-conditioned space to another air-conditioned space in the home, the difference between the indoor temperature and the target set temperature causes a loss of comfort. can be suppressed.

・Embodiment 3
In the above-described embodiment, the determination unit 132 calculated the expected time of occupancy in the air-conditioned space based on statistical values. However, the determination unit 132 may calculate the expected time of being in the air-conditioned space using a method other than the statistical value. For example, the determining unit 132 may calculate the expected time of occupancy in the air-conditioned space by using an estimation model generated using occupancy information indicating the occupancy status of the air-conditioned space as learning data.

FIG. 8 is a diagram schematically showing functions of the indoor unit 1. As shown in FIG.
The acquisition unit 131 acquires activity information indicating the activity state of the user stored in the sensor information storage unit 4 as sensor information.

The determination unit 132 inputs the sensor information acquired by the acquisition unit 131 to the estimation model 132a, and sets the time output from the estimation model 132a as the expected time of occupancy in the air-conditioned space.

・Embodiment 4
In the above-described embodiment, the control unit 133 controls the air volume of the blower unit 14 to reduce the unpleasant feeling given to the user by the rotation noise of the blower fan of the blower unit 14 . However, the notification sound from the indoor unit 1 may make the user feel uncomfortable. Therefore, the control unit 133 controls the volume of the sound emitting unit of the indoor unit 1 in addition to controlling the air volume of the air blowing unit 14, thereby reducing the discomfort given to the user by the notification sound of the sound emitting unit. may

1 and 2 in that a sound emitting unit 19 is provided.

FIG. 10 is a flow chart showing the processing of the indoor unit 1. As shown in FIG.
The acquisition unit 131 acquires activity information indicating the activity state of the user as sensor information (step S200). The determination unit 132 determines whether the activity state of the user is active or inactive based on the sensor information acquired by the acquisition unit 131 (step S201). When the activity state of the user indicates that the user is active (S201: YES), the control section 133 maintains the volume of the sound emitting section 19. FIG. Also, the control unit 133 maintains the air volume in the automatic operation mode (S202). On the other hand, when the activity state of the user indicates that the user is inactive (S201: NO), the control unit 133 controls the volume of the sound emitting unit 19 to be smaller than when the activity state is determined to be "active". to control. Further, the control unit 133 controls the air volume of the blower unit 14 so as to be weaker than the air volume in the silent mode, that is, when the user's activity state is determined to be "active" (S203).

As described above, the control unit 133 controls the volume of the sound emitting unit 19 to be lower when the user's activity state indicates inactivity than when the user's activity state indicates activity. Control. In this way, by performing air conditioning while suppressing noise generated from the indoor unit 1, the control unit 133 can achieve the effects of the first embodiment while not being active (for example, when sleeping). It is possible to suppress the user's discomfort such as being unable to fall asleep.

Other Application Examples In the above-described embodiment, when the activity state of the user indicates "active", the control unit 133 controls the air volume of the blower unit 14 so as to achieve the air volume of the automatic operation mode. However, the controller 133 is not limited to the air volume in the automatic operation mode, and may set any preset air volume (strong, medium, weak, etc.).

In the above-described embodiment, the determination unit 132 determines whether or not the user is present in the air-conditioned space based on the sensor information acquired by the acquisition unit 131 . However, the determination unit 132 may detect whether or not the user is present in the air-conditioned space based on the detection result of the detection unit 15 . In this case, the detection unit 15 detects, for example, imaging data generated by imaging the air-conditioned space, heat data generated by detecting heat in the air-conditioned space, or sound data generated in the air-conditioned space.
