Detailed Description
Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same or similar components are denoted by the same reference numerals, and description thereof will not be repeated.
(first embodiment)
An electronic device 1 according to a first embodiment of the present invention will be described below with reference to fig. 1 and 2. First, the electronic apparatus 1 is explained with reference to fig. 1. The electronic device 1 is installed indoors in a building. The electronic device 1 is, for example, a home appliance. Examples of household appliances are air purifiers, air conditioners, humidifiers, heaters, fans or lighting devices.
Fig. 1 is a diagram showing an electronic apparatus 1. As shown in fig. 1, the electronic apparatus 1 includes a detection section 3, a storage section 5, and a control section 7. The control unit 7 includes a determination unit 9 and an operation control unit 11.
The detection unit 3 detects whether or not a predetermined operation is performed on the electronic device 1. The detection unit 3 is, for example, a sensor. The detection unit 3 outputs a signal value (hereinafter referred to as "first signal value FV") indicating a detection result of the detection unit 3 to the control unit 7. The first signal value FV indicates whether or not a predetermined operation has been performed on the electronic apparatus 1. The first signal value FV may be output as an analog signal or as a digital signal.
The storage section 5 includes a storage device for storing data and computer programs. The storage section 5 includes a main storage device such as a semiconductor memory and an auxiliary storage device such as a semiconductor memory and/or a hard disk drive. The storage section 5 may also contain a removable medium.
The control Unit 7 includes a processor such as a CPU (Central Processing Unit). The processor of the control unit 7 executes the computer program stored in the storage device of the storage unit 5, and functions as the determination unit 9 and the operation control unit 11.
The determination unit 9 determines whether or not a person is present in the room in which the electronic apparatus 1 is installed, based on the detection result of the detection unit 3. Therefore, according to the first embodiment, whether or not a person is present in a room can be detected regardless of the presence or absence of a person in the room.
Specifically, when the detection unit 3 detects that the predetermined operation is performed on the electronic device 1, the determination unit 9 determines that a person is present in the room. On the other hand, when the detection unit 3 does not detect that the predetermined operation has been performed on the electronic device 1, the determination unit 9 determines that no person is present in the room.
The operation control unit 11 controls the electronic apparatus 1 based on the determination result of the determination unit 9. Therefore, the operation control unit 11 can operate the electronic apparatus 1 according to whether or not a person is present in the room.
Next, the processing executed by the electronic apparatus 1 is described with reference to fig. 1 and 2. Fig. 2 is a flowchart showing a process performed by the electronic apparatus 1. As shown in fig. 2, the process performed by the electronic apparatus 1 includes steps S1 to S7.
As shown in fig. 1 and 2, in step S1, the determination unit 9 of the electronic device 1 acquires the first signal value FV indicating the detection result of the detection unit 3 from the detection unit 3.
In step S3, the determination unit 9 determines whether or not there is a person in the room based on the first signal value FV.
Specifically, when the first signal value FV of the detection unit 3 indicates that the predetermined operation has been performed on the electronic device 1, the determination unit 9 determines that a person is present in the room (yes in step S3), and the process proceeds to step S5.
Then, in step S5, the operation control unit 11 executes first operation control on the electronic device 1. The first operation control indicates that the operation state of the electronic apparatus 1 is changed according to the presence of a person in the room. For example, the control for changing the operating state of the electronic device 1 is as follows: if the determination at step S3 is affirmative, the operation of the electronic apparatus 1 is started when the electronic apparatus 1 is in the stopped state. For example, the control for changing the operating state of the electronic device 1 is as follows: the operation of the electronic apparatus 1 is changed to an operation more active than the operation of the electronic apparatus 1 determined in step S3 as affirmative determination.
On the other hand, when the first signal value FV of the detection unit 3 indicates that the predetermined operation has not been performed on the electronic apparatus 1, the determination unit 9 determines that no person is present in the room (no in step S3), and the process proceeds to step S7.
Then, in step S7, the operation control unit 11 executes second operation control on the electronic device 1. The second operation control indicates that the operation state of the electronic device 1 is changed according to absence of a person in the room. For example, the control for changing the operating state of the electronic device 1 is as follows: in the negative judgment at step S3, the electronic apparatus 1 is stopped while the electronic apparatus 1 is operating. For example, the control for changing the operating state of the electronic device 1 is as follows: the operation of the electronic apparatus 1 is changed to an operation slower than the operation of the electronic apparatus 1 at the time of the negative determination at step S3.
(second embodiment)
An electronic device 1A according to a second embodiment of the present invention is described with reference to fig. 3 and 4. The second embodiment is mainly different from the first embodiment in that the electronic apparatus 1A according to the second embodiment includes a human body sensor 21. Hereinafter, differences between the second embodiment and the first embodiment will be mainly described.
First, the electronic apparatus 1A is explained with reference to fig. 3. The electronic device 1A is, for example, a home appliance as in the first embodiment.
Fig. 3 is a diagram showing the electronic apparatus 1A. As shown in fig. 3, the electronic device 1A further includes a human body sensor 21 in addition to the configuration of the electronic device 1 according to the first embodiment.
The human body sensor 21 detects the activity of a human in the room. In the second embodiment, the human body sensor 21 includes a pyroelectric sensor. The human body sensor 21 captures a change in heat (infrared ray amount) generated by the movement of the human body, and outputs a signal value (hereinafter referred to as "second signal value SV") indicating the detection result of the human body sensor 21 to the control unit 7. The second signal value SV indicates whether or not a person is present in the room. The second signal value SV may be output as an analog signal or as a digital signal.
The determination unit 9 determines whether or not a person is present in the room based on the detection result of the detection unit 3 and the detection result of the human body sensor 21. That is, the determination unit 9 determines whether or not a person is present in the room based on the detection results of the plurality of detection units (the detection unit 3 and the human body sensor 21 in the second embodiment) that adopt mutually different detection methods. Therefore, according to the second embodiment, it is possible to determine whether or not a person is present in the room with high accuracy, as compared with the case where only the human body sensor 21 or the detection unit 3 is provided. In other words, it is possible to suppress erroneous determination as to whether or not a person is present. For example, it is possible to suppress the determination that no person is present in the room when a person is actually present in the room.
Specifically, even when the human body sensor 21 does not detect a person in the room, the determination unit 9 determines that a person in the room is present when the detection unit 3 detects that the predetermined operation is performed on the electronic device 1A. For example, even when a person is present indoors and is located in an area outside the detection range of the human body sensor 21, the determination unit 9 determines that a person is present indoors as long as the detection unit 3 detects that a predetermined operation is performed on the electronic device 1A. That is, the detection unit 3 supplements the detection performance of the human body sensor 21, and can suppress erroneous determination as to whether or not a person is present.
On the other hand, even when the detection unit 3 does not detect the predetermined operation of the electronic device 1A, the determination unit 9 determines that a person is present in the room when the human body sensor 21 detects that a person is present in the room. That is, the human body sensor 21 supplements the detection performance of the detection unit 3, and can suppress erroneous determination as to whether or not a person is present.
On the other hand, when the human body sensor 21 does not detect a person in the room and the detection unit 3 does not detect a predetermined operation on the electronic device 1A, the determination unit 9 determines that no person is present in the room.
When the human body sensor 21 detects that a person is present in the room and the detection unit 3 detects that the electronic device 1A has been operated in a predetermined manner, the determination unit 9 determines that a person is present in the room.
The operation control unit 11 controls the electronic device 1A based on the determination result of the determination unit 9. Therefore, the operation control unit 11 can operate the electronic device 1A according to whether or not a person is present in the room.
Next, the processing executed by the electronic apparatus 1A is described with reference to fig. 3 and 4. Fig. 4 is a flowchart showing a process executed by the electronic apparatus 1A. As shown in fig. 4, the process performed by the electronic apparatus 1A includes steps S21 to S31.
As shown in fig. 3 and 4, in step S21, the determination unit 9 of the electronic device 1A acquires the second signal value SV indicating the detection result of the human body sensor 21 from the human body sensor 21.
In step S23, the determination unit 9 determines whether or not there is a person in the room based on the second signal value SV.
Specifically, when the second signal value SV from the human body sensor 21 indicates that a person is present in the room, the determination unit 9 determines that a person is present in the room (yes in step S23), and the process proceeds to step S29.
On the other hand, when the second signal value SV from the human body sensor 21 indicates that no person is present in the room, the determination unit 9 determines that no person is present in the room (no in step S23), and the process proceeds to step S25.
In step S25, the determination unit 9 acquires the first signal value FV indicating the detection result of the detection unit 3 from the detection unit 3.
In step S27, the determination unit 9 determines whether or not there is a person in the room based on the first signal value FV.
Specifically, when the first signal value FV of the detection unit 3 indicates that the predetermined operation has been performed on the electronic device 1A, the determination unit 9 determines that there is a person in the room (yes in step S27), and the process proceeds to step S29.
On the other hand, when the first signal value FV of the detection unit 3 indicates that the predetermined operation has not been performed on the electronic apparatus 1A, the determination unit 9 determines that no person is present in the room (no in step S27), and the process proceeds to step S31.
In step S31, the operation control unit 11 executes second operation control on the electronic device 1A. The second operation control of step S31 is the same as the second operation control of step S7 of fig. 2.
On the other hand, after the affirmative determination at step S23 or after the affirmative determination at step S27, the operation control unit 11 executes the first operation control on the electronic device 1A at step S29. The first operation control of step S29 is the same as the first operation control of step S5 of fig. 2.
The order of step S21 and step S25 is not particularly limited. For example, step S21 and step S23 may also be performed after step S25 and step S27.
(third embodiment)
An air cleaner 1B according to a third embodiment of the present invention will be described with reference to fig. 5 to 8. The third embodiment is mainly different from the second embodiment in that the electronic device according to the third embodiment is an air cleaner 1B. Hereinafter, differences between the third embodiment and the second embodiment will be mainly described.
Fig. 5 is a diagram showing the air cleaner 1B. The air cleaner 1B corresponds to an example of "electronic equipment". The air cleaner 1B is installed in a room of a building, and collects dust in the air. As shown in fig. 5, the air cleaner 1B further includes a fan 51, a filter 53, a display unit 55, and a sensor unit 57 in addition to the configuration of the electronic device 1A according to the second embodiment.
The sensor section 57 detects the state in the room. In the third embodiment, the sensor portion 57 includes at least one of a dust sensor and an odor sensor. The dust sensor detects the amount of dust in the room. The odor sensor detects an indoor odor. When the sensitivity of at least one of the dust sensor and the odor sensor is set to "high", the air cleaner 1B quickly detects and removes dust and odor.
The air cleaner 1B further includes a humidifier 31, an ion generation unit 33, a plate-like member 35, and a remote controller 37. The humidifier 31 includes a water storage container 31a that stores water used for humidifying the chamber. The detection unit 3 detects whether or not a predetermined operation is performed on the air cleaner 1B. Specifically, the detection unit 3 includes an operation unit 40, a water level detection unit 41, a first attachment/detachment detection unit 43, a second attachment/detachment detection unit 45, and an infrared ray reception unit 47.
The operation unit 40 detects a user operation and accepts the user operation. When the operation unit 40 receives the operation by the user, the determination unit 9 determines that the first predetermined operation is performed on the air cleaner 1B.
The determination that the first predetermined operation is performed corresponds to the determination that there is a person in the room. According to the third embodiment, the presence of a person in the room can be easily determined by detecting the operation of the user by the operation unit 40. The first prescribed operation corresponds to an example of "prescribed operation".
Specifically, the operation unit 40 outputs a signal value indicating the detection result of the operation unit 40 (hereinafter referred to as "operation signal value SG 1") to the control unit 7. The operation unit 40 includes, for example, one or more keys (not shown). Therefore, when the key is pressed, the operation unit 40 outputs an operation signal value SG1 indicating that the user operation is accepted to the control unit 7. On the other hand, when the key is not pressed, the operation unit 40 outputs an operation signal value SG1 indicating that the user operation is not accepted to the control unit 7.
The humidifier 31 vaporizes water stored in the water storage container 31a, and humidifies the room by including moisture in the air. The water level detector 41 detects the water level in the water reservoir 31 a. When the water level detector 41 detects a change from a water level lower than the predetermined threshold to a water level equal to or higher than the predetermined threshold, the determiner 9 determines that the air cleaner 1B has performed the second predetermined operation.
The determination that the second predetermined operation is performed corresponds to the determination that there is a person in the room. This is because a change from a water level below the predetermined threshold to a water level above the predetermined threshold indicates that the user has replenished water into the water storage tank 31 a. According to the third embodiment, the water level of the water storage container 31a is detected by the water level detecting unit 41, so that it is possible to easily determine that a person is present in the room. The second prescribed operation corresponds to an example of "prescribed operation".
Specifically, water level detector 41 outputs a signal value indicating the detection result of water level detector 41 (hereinafter referred to as "water level signal value SG 2") to controller 7. For example, the water level detector 41 includes a float (not shown), a magnet (not shown) provided inside the float, and a magnetic sensor (not shown). The float is disposed in the water storage tank 31 a. The magnetic sensor includes, for example, a hall element.
When the water level in the water reservoir 31a is equal to or higher than a predetermined threshold value, the magnetic sensor detects the magnet inside the float. As a result, water level detector 41 outputs water level signal value SG2 indicating that the water level is equal to or higher than the predetermined threshold value to controller 7. A water level above a predetermined threshold indicates "water" in the water reservoir 31 a.
On the other hand, when the water level in the water reservoir 31a is lower than the predetermined threshold value, the magnet inside the float is separated from the magnetic sensor, and therefore the magnetic sensor does not detect the magnet inside the float. As a result, water level detector 41 outputs water level signal value SG2 indicating that the water level is lower than the predetermined threshold value to controller 7. A water level below a prescribed threshold indicates "no" water in the reservoir 31 a.
The ion generating unit 33 generates ions and releases them into the air in the room. The ion generating unit 33 is detachable from the main body BD of the air cleaner 1B. The first attachment/detachment detecting portion 43 detects attachment/detachment of the ion generating unit 33 to/from the main body BD of the air cleaner 1B. When the first attachment/detachment detecting portion 43 detects that the ion generating unit 33 has been detached from the main body BD or that the ion generating unit 33 has been attached to the main body BD, the determining portion 9 determines that the air cleaner 1B has performed the third predetermined operation.
The determination that the third predetermined operation is performed corresponds to the determination that there is a person in the room. According to the third embodiment, by detecting the attachment/detachment of the ion generating unit 33, it is possible to easily determine the presence of a person in the room. The third prescribed operation corresponds to an example of "prescribed operation".
Specifically, the first attachment/detachment detecting unit 43 outputs a signal value (hereinafter referred to as "first attachment/detachment signal value SG 1A") indicating a detection result of the first attachment/detachment detecting unit 43 to the control unit 7. For example, the first attachment/detachment detection portion 43 includes a first terminal portion (not shown) and a second terminal portion (not shown).
When the ion generating unit 33 is mounted on the main body BD, a power supply voltage is supplied from the main body BD to the ion generating unit 33 via the first terminal portion. When the power supply voltage is supplied to the ion generating unit 33, the second terminal portion outputs a first loading/unloading signal value SG1A (for example, a voltage of the same level as the level of the power supply voltage) indicating that the ion generating unit 33 is connected to the main body BD to the control portion 7.
On the other hand, when the ion generating unit 33 is detached from the main body BD, the power supply voltage is not supplied to the ion generating unit 33. When the power supply voltage is not supplied to the ion generating unit 33, the second terminal portion outputs a first loading/unloading signal value SG1A (e.g., a voltage of zero level) indicating that the ion generating unit 33 is not connected to the main body BD to the control portion 7.
The plate-like member 35 constitutes an outer wall of the air cleaner 1B. The plate-like member 35 is detachable from the main body BD of the air cleaner 1B. The plate-like member 35 is, for example, a panel disposed on the rear surface of the air cleaner 1B. The second attachment/detachment detecting portion 45 detects attachment/detachment of the plate-like member 35 to/from the air cleaner 1B. When the second attachment/detachment detecting portion 45 detects that the plate-like member 35 has been detached from the main body BD or that the plate-like member 35 has been attached to the main body BD, the determining portion 9 determines that the air cleaner 1B has been subjected to the fourth predetermined operation.
The determination that the fourth predetermined operation is performed corresponds to the determination that there is a person in the room. According to the third embodiment, by detecting attachment and detachment of the plate-like member 35, it is possible to easily determine that a person is present in the room. The fourth specifying operation corresponds to an example of "specifying operation".
Specifically, the second attachment/detachment detecting unit 45 outputs a signal value indicating the detection result of the second attachment/detachment detecting unit 45 (hereinafter, referred to as "second attachment/detachment signal value SG 2A") to the control unit 7. For example, the second attachment/detachment detecting portion 45 includes a magnet (not shown) and a magnetic sensor (not shown) provided on the plate-shaped member 35. The magnetic sensor includes, for example, a hall element.
When the plate-like member 35 is attached to the main body BD, the magnetic sensor detects the magnet of the plate-like member 35. As a result, the second attachment/detachment detecting unit 45 outputs a second attachment/detachment signal value SG2A indicating that the plate-like member 35 has been attached to the main body BD to the control unit 7.
On the other hand, when the plate-like member 35 is detached from the main body BD, the magnet of the plate-like member 35 is separated from the magnetic sensor, and therefore the magnetic sensor does not detect the magnet of the plate-like member 35. As a result, the second attachment/detachment detecting unit 45 outputs a second attachment/detachment signal value SG2A indicating that the plate-like member 35 has been detached from the main body BD to the control unit 7.
The remote controller 37 transmits infrared rays for operating the air cleaner 1B to the infrared ray receiving unit 47. The infrared receiving unit 47 receives infrared rays from the remote controller 37. When the infrared receiving unit 47 receives infrared rays from the remote controller 37, the determination unit 9 determines that the fifth predetermined operation is performed.
The determination that the fifth predetermined operation is performed corresponds to the determination that there is a person in the room. This is because the reception of infrared rays from the remote controller 37 indicates that a person as a user operates the remote controller 37 indoors. According to the third embodiment, it is possible to easily determine whether a person is present in a room by receiving infrared rays from the remote controller 37. The fifth specifying operation corresponds to an example of "specifying operation".
Specifically, infrared receiving unit 47 outputs a signal value indicating the detection result of infrared receiving unit 47 (hereinafter referred to as "infrared signal value SG 3") to control unit 7. For example, the infrared receiving unit 47 includes an infrared light receiving element (not shown).
When the remote controller transmits infrared rays, the infrared light receiving element detects the infrared rays. As a result, the infrared ray receiving unit 47 outputs an infrared ray signal value SG3 indicating that infrared rays have been received from the remote controller 37 to the control unit 7.
On the other hand, when the remote controller 37 does not transmit infrared rays, the infrared light receiving element does not detect infrared rays. As a result, the infrared ray receiving unit 47 outputs an infrared ray signal value SG3 indicating that no infrared ray has been received from the remote controller 37 to the control unit 7.
In addition, when a plurality of remote controllers including the remote controller 37 are present in the room in which the air cleaner 1B is installed, the infrared receiving unit 47 may receive infrared rays from all the remote controllers. In this case, the determination unit 9 determines that the fifth predetermined operation has been performed, as long as the predetermined infrared ray (hereinafter, referred to as "predetermined infrared ray PIR") is received. For example, the remote controller 37 among the plurality of remote controllers transmits a predetermined infrared PIR.
Specifically, the determination unit 9 determines whether or not the received infrared ray is a predetermined infrared ray PIR based on a predetermined code included in the infrared ray received by the infrared ray reception unit 47. The prescribed code is, for example, a manufacturer code or a model code. The determination unit 9 processes only the predetermined infrared ray PIR as the valid infrared ray and processes the infrared ray other than the predetermined infrared ray PIR as the invalid infrared ray in the determination of the presence or absence of the person.
That is, the determination unit 9 determines that the fifth predetermined operation has been performed when determining that the received infrared ray is the predetermined infrared ray PIR. That is, the determination unit 9 determines that a person is present in the room based on the reception of the predetermined infrared PIR. On the other hand, when determining that the received infrared ray is different from the predetermined infrared ray PIR, the determination unit 9 determines that the fifth predetermined operation is not performed. That is, the determination unit 9 determines that no person is present in the room based on the reception of infrared rays other than the predetermined infrared PIR ray.
The determination unit 9 determines whether or not a person is present in the room and the state of the room based on the detection result of the operation unit 40, the detection result of the water level detection unit 41, the detection result of the first detachable detection unit 43, the detection result of the second detachable detection unit 45, the detection result of the infrared ray reception unit 47, and the detection result of the human body sensor 21. That is, the determination unit 9 determines whether or not a person is present in the room and the state of the room based on the detection results of the plurality of detection units (the operation unit 40, the water level detection unit 41, the first detachable detection unit 43, the second detachable detection unit 45, the infrared ray reception unit 47, and the human body sensor 21 in the third embodiment) using different detection methods.
Therefore, according to the air cleaner 1B of the third embodiment, it is possible to determine with high accuracy whether or not a person is present in the room and the state of the room, as compared with the case where only the human body sensor 21 or the detection unit 3 is provided. The indoor state is represented by the presence or absence of a person and the state of the person. The state of a person is represented by the activity level of the person. The activity level of a person is, for example, "less activity of a person" or "more activity of a person".
Specifically, even when the human body sensor 21 does not detect a person in the room, the determination unit 9 determines that the person in the room is present when any one of the operation unit 40, the water level detection unit 41, the first attachment/detachment detection unit 43, the second attachment/detachment detection unit 45, and the infrared ray reception unit 47 detects that a predetermined operation is performed on the air cleaner 1B. For example, even when a person is present indoors and is located outside the detection range of the human body sensor 21, the determination unit 9 determines that a person is present indoors if any one of the operation unit 40, the water level detection unit 41, the first attachment/detachment detection unit 43, the second attachment/detachment detection unit 45, and the infrared ray reception unit 47 detects that a predetermined operation has been performed on the electronic device 1A. That is, the operation unit 40, the water level detection unit 41, the first detachable detection unit 43, the second detachable detection unit 45, and the infrared ray reception unit 47 complement the detection performance of the human body sensor 21, thereby making it possible to suppress erroneous determination as to whether or not a person is present.
On the other hand, even when the operation unit 40, the water level detection unit 41, the first attachment/detachment detection unit 43, the second attachment/detachment detection unit 45, and the infrared ray reception unit 47 do not detect the predetermined operation of the electronic device 1A, the determination unit 9 determines that the person is present in the room when the human body sensor 21 detects that the person is present in the room. That is, the motion sensor 21 can suppress erroneous determination as to whether or not a person is present by complementing the detection performance of the operation unit 40, the water level detection unit 41, the first attachment/detachment detection unit 43, the second attachment/detachment detection unit 45, and the infrared ray reception unit 47.
The first signal value FV (the operation signal value SG1, the water level signal value SG2, the first attachment/detachment signal value SG1A, the second attachment/detachment signal value SG2A, and the infrared ray signal value SG3) indicating the detection result of the detector 3 may be output as an analog signal or as a digital signal.
Next, the processing performed by the air cleaner 1B will be described with reference to fig. 5 and 6. Fig. 6 is a flowchart showing a process performed by the air cleaner 1B. As shown in fig. 6, the process performed by the air cleaner 1B includes steps S41 to S47.
As shown in fig. 5 and 6, in step S41, the determination unit 9 controls the storage unit 5 so as to store the second signal value SV indicating the detection result of the human body sensor 21 at a fixed time interval Ta. The second signal value SV is the same as the second signal value SV according to the second embodiment. The storage unit 5 stores the second signal value SV at a constant time interval Ta.
The second signal value SV from the human body sensor 21 is at the first level in the case of detecting "presence" of a human being, and is at the second level different from the first level in the case of detecting "absence" of a human being. The detection of "having" a person means that the human body sensor 21 detects a person, that is, indicates that a person is present in the room. Detecting "no" human means that the human sensor 21 does not detect a human, i.e., indicates that no human is in the room.
Specifically, the human body sensor 21 detects the presence or absence of movement of heat every predetermined time Tb, and determines the presence or absence of detection of a human body based on the presence or absence of movement of heat. The predetermined time Tb is, for example, 25 msec. For example, the human body sensor 21 determines that "there is a human being detected" when "there is a thermal movement" for 4 or more times out of 10 times, and determines that "there is no human being detected" when "there is a thermal movement" for 3 or less times out of 10 times. When the human body sensor 21 determines that "human presence" is detected, it outputs the second signal value SV of the first level indicating that "human presence" is detected to the control unit 7. When the human body sensor 21 determines that "no" has detected a human body, it outputs a second signal value SV of a second level indicating that "no" has detected a human body to the control unit 7.
In step S43, the determination unit 9 controls the storage unit 5 so as to store the first signal value FV indicating the detection result of the detection unit 3 at a fixed time interval Ta. The storage unit 5 stores the first signal value FV at a constant time interval Ta.
The first signal value FV includes an operation signal value SG1, a water level signal value SG2, a first loading/unloading signal value SG1A, a second loading/unloading signal value SG2A, and an infrared signal value SG 3. Therefore, the storage unit 5 stores each of the operation signal value SG1, the water level signal value SG2, the first attachment/detachment signal value SG1A, the second attachment/detachment signal value SG2A, and the infrared ray signal value SG3 at regular time intervals Ta.
In step S45, the determination unit 9 determines the state of the room in which the air cleaner 1B is installed, based on the determination result of the determination process. The judgment process shows the following processing: whether or not a person is present in the room is determined based on the detection result of the detection unit 3 stored in the storage unit 5 and the detection result of the human body sensor 21 stored in the storage unit 5.
Specifically, the determination unit 9 includes a first determination unit 9a and a second determination unit 9 b. In the determination process, the first determination unit 9a determines whether or not a person is present in the room based on the first signal value FV and the second signal value SV at every predetermined time Tx. Next, the first determination unit 9a outputs the first information FN when determining that there is a person in the room. The first information FN indicates that a person is present in the room. On the other hand, when determining that no person is present in the room, the first determination unit 9a outputs the second information SN. The second information SN indicates that no person is present in the room.
The first determination unit 9a outputs either the first information FN or the second information SN every predetermined time Tx (for example, 1 second).
The second determination unit 9b counts the number of times NM1 that the first information FN is output within the predetermined determination time Ty, and then the second determination unit 9b calculates a first total time Ts1(═ NM1 × Tx) by multiplying the number of times NM1 by the predetermined time Tx, the first total time Ts1 indicates the total of the times in which it is determined that there is a person in the room within the predetermined determination time Ty, and the predetermined determination time Ty is longer than the predetermined time Tx.
The second determination unit 9b counts the number of times NM2 that the second information SN is output within the predetermined determination time Ty, and then the second determination unit 9b calculates a second total time Ts2(═ NM2 × Tx) by multiplying the number of times NM2 by the predetermined time Tx, the second total time Ts2 indicating the total of the times when it is determined that no person is present in the room within the predetermined determination time Ty.
The second determination unit 9b determines the indoor state based on the first total time Ts1 and the second total time Ts 2.
Specifically, the second determination unit 9b determines whether the indoor state is the state Sp1, the state Sp2, or the state Sp 3. State Sp1 represents an unmanned state in a room. The state Sp2 indicates a state in which there is a person in the room and the activity of the person is low. The state Sp3 represents a state in which there is a person in the room and the person is active.
The second determination unit 9b uses the first predetermined determination time Ty1 and the second predetermined determination time Ty2 as the predetermined determination time Ty in determining the indoor state. The first prescribed judgment time Ty1 is shorter than the second prescribed judgment time Ty 2. The first and second prescribed judgment times Ty1 and Ty2 are both longer than the prescribed time Tx.
The second determination unit 9b uses the first threshold TH1, the second threshold TH2, and the third threshold TH3 for determining the indoor state. The 1 st threshold TH1 is less than the 2 nd threshold TH 2.
The first predetermined determination time Ty1, the first threshold TH1, and the third threshold TH3 are used when the indoor state is the state Sp2 ("less active"). The second prescribed determination time Ty2 and the second threshold TH2 are used when the state of the room is the state Sp3 ("active-many").
Specifically, the second determination unit 9b determines the indoor state as follows.
That is, when the indoor state is the state Sp1 ("no person"), the second determination unit 9b determines that the indoor state has been switched from the state Sp1 to the state Sp2 ("low activity") when the first information FN is output.
When the indoor state is the state Sp2 ("low activity"), the second determination unit 9b determines that the indoor state has been switched from the state Sp2 to the state Sp3 ("high activity") when determining that the first total time Ts1 within the first predetermined determination time Ty1 (e.g., 1 minute) is equal to or longer than the first threshold TH1 (e.g., 25 seconds).
When the indoor state is the state Sp2 ("low activity"), the second determination unit 9b determines that the indoor state has been switched from the state Sp2 to the state Sp1 ("no person") when it determines that the second total time Ts2 is equal to or longer than the third threshold TH3 (e.g., 15 minutes).
When the indoor state is the state Sp3 ("active high"), the second determination unit 9b determines that the indoor state has been changed from the state Sp3 to the state Sp2 ("active low") when determining that the first total time Ts1 within the second predetermined determination time Ty2 (for example, 5 minutes) is less than the second threshold TH2 (for example, 30 seconds).
In step S47, the operation control unit 11 controls the air cleaner 1B according to the indoor state. Specifically, the operation control unit 11 controls the control target according to the indoor state. In the third embodiment, the control targets are the fan 51, the display unit 55, and the sensor unit 57.
For example, when the indoor state is determined to be the state Sp1 ("nobody"), the operation control unit 11 controls the display unit 4 to decrease the luminance of the display unit 4 or to turn off the display unit 4. For example, when the indoor state is determined to be the state Sp3 ("active high"), the operation control unit 11 sets the sensitivity of the sensor unit 57 to "high" and controls the fan 51 so as to increase the amount of air blown by the fan 51. For example, when the indoor state is determined to be the state Sp2 ("low activity"), the operation control unit 11 controls the air cleaner 1B to perform normal operation.
Next, the determination process of the air cleaner 1B will be described with reference to fig. 5, 7, and 8. Fig. 7 and 8 are flowcharts showing the judgment process. As shown in fig. 7 and 8, the judgment process includes steps S61 to S91.
As shown in fig. 5 and 7, in step S61, the first determination unit 9a sets a timer to a predetermined time Tx and starts the timer. As a result, the timer starts measuring time.
In step S63, the first determination unit 9a determines whether or not the time measured by the timer has reached a predetermined time Tx (e.g., 1 second).
In the case of a negative determination (no in step S63), the process waits in step S63.
On the other hand, in the case of an affirmative determination (yes in step S63), the process advances to step S65.
In step S65, the first determination unit 9a acquires the detection result of the human body sensor 21 (i.e., the plurality of second signal values SV stored for the predetermined time Tx) for the predetermined time Tx from the storage unit 5.
In step S67, the first determination unit 9a determines whether or not there is a person in the room based on the detection result of the human body sensor 21 for the predetermined time Tx.
In the case of an affirmative determination (yes in step S67), the process advances to step S89.
On the other hand, in the case of a negative determination (no in step S67), the process advances to step S69.
In step S69, first determination unit 9a acquires the detection result of operation unit 40 during predetermined time Tx (i.e., the plurality of operation signal values SG1 stored during predetermined time Tx) from storage unit 5.
In step S71, the first determination unit 9a determines whether or not there is a person in the room based on the detection result of the operation unit 40 during the predetermined time Tx.
In the case of an affirmative determination (yes in step S71), the process advances to step S89.
On the other hand, in the case of a negative determination (no in step S71), the process advances to step S73.
In step S73, first determination unit 9a obtains, from storage unit 5, the detection result of water level detection unit 41 for predetermined time Tx (i.e., the plurality of water level signal values SG2 stored for predetermined time Tx).
In step S75, the first determination unit 9a determines whether or not there is a person in the room based on the detection result of the water level detection unit 41 for the predetermined time Tx.
In the case of an affirmative determination (yes in step S75), the process advances to step S89.
On the other hand, in the case of a negative determination (no in step S75), the process proceeds to step S77 in fig. 8.
As shown in fig. 8, in step S77, the first determination unit 9a acquires, from the storage unit 5, the detection result of the first loading/unloading detection unit 43 within the predetermined time Tx (that is, the plurality of first loading/unloading signal values SG1A stored within the predetermined time Tx).
In step S79, the first determination unit 9a determines whether or not a person is present in the room based on the detection result of the first attachment/detachment detection unit 43 within the predetermined time Tx.
If the determination is affirmative (yes in step S79), the process proceeds to step S89 of fig. 7.
On the other hand, in the case of a negative determination (no in step S79), the process advances to step S81.
In step S81, the first determination unit 9a acquires, from the storage unit 5, the detection result of the second attachment/detachment detection unit 45 for the predetermined time Tx (that is, the plurality of second attachment/detachment signal values SG2A stored for the predetermined time Tx).
In step S83, the first determination unit 9a determines whether or not a person is present in the room based on the detection result of the second attachment/detachment detection unit 45 within the predetermined time Tx.
In the case of an affirmative determination (yes in step S83), the process advances to step S89.
On the other hand, in the case of a negative determination (no in step S83), the process advances to step S85.
In step S85, first determination unit 9a acquires the detection result of infrared ray reception unit 47 for predetermined time Tx (that is, the plurality of infrared ray signal values SG3 stored for predetermined time Tx) from storage unit 5.
In step S87, the first determination unit 9a determines whether or not there is a person in the room based on the detection result of the infrared ray reception unit 47 for the predetermined time Tx.
If the determination is affirmative (yes in step S87), the process proceeds to step S89 of fig. 7.
On the other hand, in the case of a negative determination (no in step S87), the process advances to step S91.
In step S91, the first determination unit 91a outputs the second information SN indicating that no person is present to the second determination unit 91 b. Then, the process returns to step S61 of fig. 7.
On the other hand, as shown in fig. 7 and 8, after the affirmative determination in step S67, step S71, step S75, step S79, step S83, or step S87, the first determination portion 91a outputs the first information FN indicating the presence of the person to the second determination portion 91b in step S89. Then, the process returns to step S61.
