Description

  The present invention relates to an air conditioner, and more particularly to an air conditioner that changes a driving index of comfort according to the number of people in a room.

  The conventional air conditioner calculates whether one person or a plurality of persons are present in the section, and in the case of one person, the environment is controlled to the optimum value of the stored individual, and in the case of a plurality of persons, the stored value is stored. Individual comfortable air conditioning is realized by controlling the average value or the predetermined value of the optimum values of a plurality of people (see, for example, Patent Document 1).

FIG. 42 shows an operation flowchart of the conventional environmental control device described in Patent Document 1.
As shown in FIG. 42, the card reader provided outside the room is checked in step 41, while the card reader provided inside the room is checked in step 42. The number of persons is calculated to determine whether there are multiple persons. When the number of people in the room is one, the optimum value of the person is extracted from the ROM in step 46 and controlled. When there are a plurality of people in the room, the average value of the optimum value of each person or The environment is controlled by extracting a predetermined value between the maximum value and the minimum value.

  Also, the occupants are identified based on the occupant identification information transmitted from the wireless ID tag, and the air volume is calculated based on the PMV value (PMV: Predicted Mean Vote) of the individual registered in advance. An air conditioning control system that realizes individual comfortable air conditioning by adjusting the above has been proposed (see, for example, Patent Document 2).

FIG. 43 shows a configuration of a conventional air conditioning control system 1 described in Patent Document 2. As shown in FIG.
As shown in FIG. 43, this air conditioning control system 1 is composed of a occupant management system 10 and a central monitoring system 20 connected to each other via a router 30, and the occupant management system 10 is One provided with PC11A-D which a room person operates, radio | wireless ID tag 12A-D which a room person holds, the antenna 13, a room person management server 14, and a room person identification part (not shown) The central monitoring system 20 includes an air conditioning control device 21, controllers 22 </ b> A and 22 </ b> B, a heat source device 23, an air conditioner 24, and a measurement unit 25.

The operation button group 102 is a generic name for various buttons for operating the indoor unit 200 and various operation buttons for setting and selecting. For example, an operation off / on button, a temperature setting button, a humidity setting button, and the like. is there. The feature setting unit 101 may be provided with an operation button alone or may be a function that can be set from the buttons of the operation button group 102. In the present embodiment, it is assumed that an operation button is provided alone. In addition, in the present embodiment, the characteristic setting means 101 displays unique information (unique name, biological information) and comfort characteristic (physical constitution, physical condition, activity state) by displaying selectable information on the display unit 104. The operation button group 102 is used to select and set a unique name and comfort characteristics (physical condition, physical condition, activity state), and biological information is set by the biological information acquisition means 207 (see FIG. 3) of the indoor unit 200. However, the present invention is not particularly limited to this and may be set by another method. However, the types of personal comfort features that can be set by the feature setting unit 101 are stored in the storage unit 103 in advance, and similar information is also stored in the storage unit 201 (see FIG. 3) of the indoor unit 200. And In addition, it is assumed that at least the unique name among the information set by the feature setting unit 101 is managed by the storage unit 103. As a result, the user can call and change / delete the set personal comfort feature based on the unique name.

  Below, the setting method of the personal comfort characteristic in this Embodiment is demonstrated using FIGS. 7-25.

  FIG. 7 shows a feature setting process flow. When the feature setting unit 101 is selected, the control unit 105 checks whether a unique name has already been registered in the storage unit 103 (S701). If no unique name is registered (NO in S702), a new feature setting process is performed. When the unique name is registered (YES in S702), the options of “new”, “change”, and “delete” are displayed on the display unit 104. The operator uses the operation button group 102 to select / determine a desired operation from the options of “new”, “change”, and “delete”. When the control unit 105 detects that “new” has been selected (YES in S703), the control unit 105 performs a new feature setting process (S704), and detects that “change” has been selected (NO in S703, and In step S705, a feature change process is performed (S706). When it is detected that “delete” is selected (NO in S703 and NO in S705), a feature deletion process is performed (S707).

  As a method for selecting / determining the options displayed on the display unit 104, the cursor may be displayed on the display unit 104, and the cursor may be operated with the buttons of the operation button group 102 to select / determine. Selection / determination may be performed by pressing a button corresponding to the same meaning from the buttons in the button group 102. When the feature setting unit 101 is provided with an operation button alone, new, change, or deletion may be selected by the number of times the feature setting unit 101 is pressed. There is no particular limitation as long as “new”, “change”, and “delete” can be selected by any method.

  Note that if the input from the operator cannot be detected for a certain period of time, the feature setting process is terminated.

[New feature setting process]
FIG. 8 shows a new feature setting process flow which is a subroutine of the feature setting process flow of FIG. In the new feature setting process, the control unit 105 first performs a unique name setting process (S801 in FIG. 8). If no input from the operator is detected for a certain period of time, the unique name setting process is terminated and the feature new setting process is terminated.

  FIG. 9 shows a unique name setting process flow which is a subroutine in the new feature setting process flow of FIG. The control unit 105 causes the display unit 104 to display a message requesting the setting of the unique name and the Japanese syllabary (S901). A display example of the display unit 104 is shown in FIG. The operator uses the operation button group 102 to select from the Japanese syllabary and set a unique name. At this time, all the fifty sounds may be displayed on the display unit 104 or may be displayed for each row. In addition, it is also possible to select a Japanese phonetic character as in the case of inputting a mail character of a mobile phone by continuously pressing any button of the operation button group 102 without displaying the Japanese phonetic character. Further, the remote controller 100 may be provided with voice input means and set by voice. The characters that can be displayed are not limited to hiragana, but may be katakana, kanji, or alphabet. If the unique name can be set by some method, it is not limited to this.

  When the control unit 105 detects the end of the setting of the unique name (YES in S902), the set unique name is insufficient in the number of characters (NO in S903), the number of characters is over (YES in S903 and YES in S904) or stored in the storage unit 103. If it is duplicated with the unique name to be managed (YES in S903, NO in S904, and YES in S905), it is determined as an error, and the display unit 104 is displayed to input again. If the storage unit 103 has insufficient area for managing the unique name (NO in S906), a message indicating that setting is not possible is displayed on the display unit 104 (S908), and the process ends. It should be noted that a confirmation process of whether or not there is a free area in the storage unit 103 may be inserted at the beginning of the unique name setting process. Thereby, an operator is not made useless work. If there is an empty area in the storage unit 103 (YES in S906), the unique name set in the storage unit 103 is stored in the temporary memory of the storage unit 103, and the process ends (S907).

  When the unique name is set, the control unit 105 performs comfort characteristic setting processing (S802 in FIG. 8). If no input from the operator is detected for a certain period of time, the comfort feature setting process is terminated and the feature new setting process is terminated. At this time, the unique name set in the unique name setting process is deleted.

  FIG. 11 shows a comfort feature setting process flow which is a subroutine in FIG. The control unit 105 causes the display unit 104 to display the settable comfort features stored in the storage unit 103 (S1101). A display example of the display unit 104 is shown in FIG. At this time, all comfort features including constitution, physical condition, and activity state may be displayed in a list, or may be displayed separately for constitution, physical condition and activity state, or may be displayed separately for each type of feature. Good. The user uses the operation button group 102 to select / set a comfort feature to be set from the displayed features. At this time, the comfort feature to be set may be one or plural. It is also possible to set only the constitution, only the physical condition, or only the activity state. However, it is not possible to set a constitution, physical condition, and activity state that conflict with each other such as cold and hot. Also, it is assumed that comfort features other than those registered in advance in the storage unit 103 cannot be set. If it is not set, it is automatically registered to be in the standard constitution / physical condition / activity state.

  Although the present embodiment has been described on the assumption that comfort characteristics that can be set are displayed on the display unit 104, buttons for various settings may be directly provided. If the comfort feature can be set by some method, it is not limited to this.

  When the control unit 105 detects the end of the setting (YES in S1102), the control unit 105 determines whether a comfort feature related to the constitution is set. When the comfort feature related to the constitution is not set (NO in S1103), a standard value is set as the comfort feature related to the constitution (S1104). When it is detected that the comfort feature related to the constitution is set (YES in S1103), the constitution setting process is performed (S1105).

  Next, it is determined whether or not a comfort feature related to physical condition has been set. If the comfort characteristic related to physical condition is not set (NO in S1106), a standard value is set as the comfort characteristic related to physical condition (S1107), and the set comfort characteristic is stored in the temporary memory of the storage unit 103 for processing. Exit. If it is detected that the comfort characteristic related to the physical condition is set (YES in S1106), the physical condition setting process is performed (S1108), the set comfort characteristic is stored in the temporary memory of the storage unit 103, and the process ends. .

  Note that the setting of the comfort characteristic related to the activity state is the same as the setting of the comfort characteristic related to the constitution or physical condition, and therefore the description thereof is omitted.

  FIG. 12 shows a comfort feature constitution setting process flow which is a subroutine of the comfort feature setting process flow shown in FIG. A set value corresponding to the constitution set as the comfort feature related to the constitution is set, and the number of settings is counted up (S1201). If no other constitution is set (NO in S1202), the constitution setting process is terminated. If another constitution is set (YES in S1202), it is checked whether or not the set number exceeds the maximum set number. If not (NO in S1203), the constitution is additionally set. If the maximum setting number is exceeded (YES in S1203), the constitution setting process is terminated.

  The maximum number of constitutions is determined for each system, and may be one or plural. Moreover, the set value for each constitution is also system-dependent and is not particularly limited.

  With this configuration, for example, adjust the temperature for a cold / hot constitution, adjust the humidity for an atopy or dry skin constitution, and the air purification function for an allergy constitution, etc. Can be operated.

  FIG. 13 is also a subroutine of FIG. 11 similar to FIG. 12, and shows a comfort characteristic physical condition setting process flow. Since the physical condition setting process flow is the same as the physical condition setting process flow, description thereof is omitted. When the unique name / comfort characteristic is set, the control unit 105 performs biometric information setting processing (S803 in FIG. 8).

  FIG. 15 shows a biometric information setting process flow which is a subroutine in FIG. The control unit 105 causes the display unit 104 to display a message requesting setting of biometric information, and requests the indoor unit 200 to acquire biometric information via the communication unit 300 (S1501).

  FIG. 16 shows a display example of the display unit 104, and FIG. 17 shows a message transmission / reception sequence with the indoor unit 200. When receiving the biometric information acquisition request from the remote controller 100, the control unit 208 of the indoor unit 200 acquires the biometric information by the biometric information acquisition unit 207, and acquires the empty information (described later) in the comfort management table 206 of the storage unit 201. Registered biometric information. The control unit 208 of the indoor unit 200 transmits the entry number registered in the comfort management table 206 to the control unit 105 of the remote controller 100 via the communication unit 300.

  Upon receiving the entry number (YES in S1502), the control unit 105 transmits the comfort characteristic and the unique name stored in the temporary memory of the set storage unit together with the entry number to the indoor unit 200 via the communication unit 300 ( S1503)), the storage unit 103 stores the unique name and the entry number in association with each other (S1504), displays a setting completion message on the display unit 104, and ends the processing (S1505). At this time, the unique name and the comfort feature stored in the temporary memory are deleted.

  In addition, when the control unit 105 receives a registration failure notification from the control unit 208 of the indoor unit 200 (NO in S1502 and YES in S1506), the comfort feature and the unique name stored in the temporary memory are deleted ( In step S1507, a message indicating that setting is not possible is displayed on the display unit 104, and the process ends (S1508).

  In addition, when a response cannot be received from the control unit 208 of the indoor unit 200 within the set time (NO in S1502, NO in S1506, and NO in S1509), the acquisition process is performed again. If the re-acquisition process has failed a plurality of times (NO in S1502, NO in S1506, YES in S1509, and YES in S1510), the same process as when a failure notification is received is performed.

  Note that one or more pieces of biometric information may be acquired. By obtaining a plurality, it becomes possible to determine an individual more accurately.

  Alternatively, the remote controller 100 may include biological information acquisition means, acquire biological information with the remote controller 100, and transmit all information to the indoor unit 200 (FIGS. 18 and 19). In this case, the number of the entry registered in the comfort management table 206 is received from the indoor unit 200 as a setting response, and the unique name and the entry number are stored in the storage unit 103 in association with each other. If no response is received from the control unit 208 of the indoor unit 200 within the set time, it is determined as an error, and all information is transmitted to the indoor unit 200 again. When a registration failure notification is received from the indoor unit control unit 208, a message indicating that setting is not possible is displayed on the display unit 104, and the process ends. At this time, the unique name and the comfort feature stored in the temporary memory in the storage unit 103 are deleted. In addition, when re-transmission fails a plurality of times, the same processing as when a failure notification is received is performed.

  The biological information acquisition unit of the remote controller 100 may be provided with a single button, or displays a biological information acquisition menu on the display unit 104, displays the cursor, and operates the cursor with the buttons of the operation button group 102. For example, if the display unit 104 of the remote controller 100 is a touch panel type, it may be possible to select by touching the screen directly. When using a device other than the remote controller 100, the settings may be set using an application or the like.

  Note that a confirmation process as to whether or not there is a free area in the storage unit 201 of the indoor unit 200 may be inserted at the beginning of the process. As a result, it is possible to confirm whether registration is possible first, and the operator is not made useless work.

[Feature change processing]
FIG. 20 shows a feature change processing flow which is a subroutine of the feature setting processing flow of FIG.
In the feature change process, the control unit 105 first performs a unique name selection process (S2001 in FIG. 20).

  FIG. 21 shows a unique name selection process flow in the feature change process flow shown in FIG. The control unit 105 causes the display unit 104 to display a message requesting selection of a unique name and a list of unique names registered in the storage unit 103 (S2101). The operator uses the operation button group 102 to select a unique name. If the input from the operator cannot be detected for a certain period of time (YES in S2102), the control unit 105 ends the feature change process.

  When detecting the selection of the unique name (NO in S2102 and YES in S2103), the control unit 105 ends the unique name selection process and performs the unique name change process (S2002 in FIG. 20).

  FIG. 22 shows a unique name change process flow in the feature change process flow shown in FIG. The control unit 105 causes the display unit 104 to display a message requesting change and a Japanese syllabary (S2201). Note that the unique name setting method is the same as the feature new setting process, and a description thereof will be omitted.

  At this time, if the input from the operator cannot be detected for a certain period of time, the unique name change process is terminated and the feature change process is terminated.

  Note that the unique name changing process may be omitted when a menu that allows the user to select “no change” is displayed in the display of S2201 and the unique name does not need to be changed.

  When the control unit 105 detects the end of the setting of the unique name (YES in S2202), it checks whether the unique name has been changed. If the unique name is terminated without being changed (NO in S2203), the unique name changing process is terminated. When the unique name is changed (YES in S2203), the set unique name is insufficient in the number of characters (NO in S2204), or when the number of characters is over (NO in S2204 and YES in S2205), it is determined as an error. It is displayed on the display unit 104 so as to input again. If it is set correctly (YES in S2204 and NO in S2205), the unique name is stored in the temporary memory (S2206).

  When the unique name process ends, the control unit 105 performs a comfort feature change process (S2003 in FIG. 20).

  The control unit 105 causes the display unit 104 to display a message requesting a change and a settable comfort feature stored in the storage unit 103 so that the currently set comfort feature can be recognized. Other processes are the same as the comfort feature setting process of FIG. When a message that requests a change is displayed and a menu that allows the user to select “no change” is displayed and the comfort feature change is not required, the comfort feature change process may be omitted.

  In this embodiment, the comfort feature change process has been described as being newly set in the same manner as the comfort feature setting process. However, the update process is performed by setting a difference from the registered comfort feature. Also good. In other words, the comfort characteristics (previously set contents) that have already been registered may be called and the user may reset only necessary portions.

  When the unique name change process and the comfort feature change process are completed, the control unit 105 performs a change notification process to transmit the information to the indoor unit 200 (S2004 in FIG. 20).

  FIG. 23 shows a message transmission / reception sequence with the indoor unit 200 in the change notification process in FIG. The control unit 105 requests the indoor unit 200 to change the comfort characteristics via the communication unit 300. At this time, the entry number of the comfort management table 206 stored in the storage unit 103 is specified based on the unique name, and the comfort characteristic to be changed is transmitted. When receiving the feature change request, the control unit 208 of the indoor unit 200 designates the entry number, transmits the feature change request to the storage unit 201, and updates the comfort feature managed by the comfort management table 206. When receiving the change response from the control unit 208 of the indoor unit 200, the control unit 105 transmits a feature update request to the storage unit 103 and formally stores the comfort feature stored in the temporary memory. At this time, if the control unit 105 fails to receive a response from the control unit 208 of the indoor unit 200 within the set time, it is determined as an error, and the change notification process is performed again. When the notification of the update failure is received from the control unit 208 of the indoor unit, a non-updateable message is displayed on the display unit 104, and the process is terminated. At this time, the comfort feature stored in the temporary memory is deleted.

[Feature deletion processing]
FIG. 24 shows a feature deletion processing flow which is a subroutine of the feature setting processing flow of FIG. In the feature deletion process, the control unit 105 first performs a unique name selection process (S2001 in FIG. 24). The unique name selection process is the same as the feature change process. When detecting the selection of the unique name, the control unit 105 performs a deletion notification process to transmit the information to be deleted to the indoor unit 200 (S2402 in FIG. 24).

  FIG. 25 shows a message transmission / reception sequence with the indoor unit 200 in the deletion notification process in the feature deletion process flow shown in FIG. The control unit 105 requests the indoor unit 200 to delete the comfort feature via the communication unit 300. At this time, the entry number of the comfort management table 206 stored in the storage unit 103 is designated and transmitted based on the unique name. When receiving the feature deletion request, the control unit 208 of the indoor unit 200 designates the entry number, transmits the feature deletion request to the storage unit 201, and deletes the comfort feature managed by the comfort management table 206. When receiving the deletion response from the control unit 208 of the indoor unit 200, the control unit 105 transmits a feature deletion request to the storage unit 103 and deletes the unique name managed by the storage unit 103. At this time, if the control unit 105 fails to receive a response from the control unit 208 of the indoor unit 200 within the set time, the control unit 105 determines that an error has occurred and performs the deletion notification process again. When notification of deletion failure is received from the control unit 208 of the indoor unit, a message indicating that deletion is not possible is displayed on the display unit 104, and the process ends.

[Functional configuration of indoor unit]
FIG. 3 is a block diagram showing a functional configuration of the indoor unit 200 according to Embodiment 1 of the present invention. In FIG. 3, the air conditioner 200 includes a storage unit 201, a human body detection unit 202, an air-conditioned space detection unit 210, a user determination unit 203, a control index determination unit 204, an air-conditioning control unit 205, a biological information acquisition unit 207, and a control unit. 208, a detection unit 209, and a communication unit 300. The detection unit 209 includes a human body detection unit 202 and a conditioned space detection unit 210 that detects the position of furniture and the like in the conditioned space, the amount of solar radiation, and the like, and a plurality of sensors that detect indoor environmental conditions such as a room temperature sensor and a humidity sensor. Means are provided to detect various temperatures, humidity, illuminance, air volume, and the like. The air-conditioned space detecting means 210 can detect the presence or absence of a person in the air-conditioned space and the position thereof. In this case, the human body detecting means 202 may be used instead. The storage unit 201 stores a comfort management table 206 in a nonvolatile memory (not shown). Note that the storage unit 201 stores comfort characteristics and the degree of correction for each comfort characteristic.

[Comfort management table]
FIG. 4A is a diagram schematically illustrating the configuration of the comfort management table 206.
In the comfort management table 206, individual comfort characteristics are managed for each individual unique information, and the management information includes a unique name, biological information, constitution, physical condition, and activity state. In addition, when there is information to be managed for each individual, it may be managed in this table as well. Hereinafter, this set of management information is referred to as an entry. An entry for which management information is not registered is called a free entry.

  The unique name is information for identifying an individual set by the feature setting unit 101 of the remote controller 100, and the user may freely register information that the user can easily remember, such as a name and a nickname. However, the same unique name cannot be set.

  The biometric information is information that uniquely identifies an individual set by the feature setting unit 101 of the remote controller 100, and personal biometric information that can uniquely identify the user, such as an image and sound, is registered. The biometric information registration means may be provided in the remote controller 100, or may be registered by the biometric information acquisition means 207 of the indoor unit 200. Further, a plurality of pieces of biometric information may be registered instead of one. By registering more than one, it is possible to improve the accuracy of identifying an individual. In addition, the biological information acquisition unit 207 may be provided with a camera in an air conditioner or a remote controller to photograph an individual, or may be provided with a microphone to record an individual voice. If you want to change or delete a set comfort feature by associating and managing the unique name and biometric information, you can specify the entry by specifying the unique name, and users can easily change or delete their information. It becomes possible. In addition, when switching driving, the unique name associated with the acquired biological information can be referred to and the user can be notified such as “Perform driving according to Mr. XX”. In addition, during personal comfort driving, the unique name or the room is displayed on the display unit 104 of the remote controller 100 or the display unit 104 provided in the indoor unit 200, so that it matches the comfort of anyone (or the room). The user can be notified in an easy-to-understand manner of driving.

  If the biometric information acquisition unit 207 is a camera, it can also be used as the human body detection unit 202. In this case, it is possible to suppress the load of image processing and the like because it is detected whether the occupants are one or more (or absent) before the occupant is determined. Further, when the air-conditioned space detection unit 210 is a camera, the human body detection unit 202 can be used as in the case where the biological information acquisition unit 207 is a camera. That is, the air-conditioned space detection unit 210, the human body detection unit 202, and the biological information acquisition unit 207 can be combined with one camera.

  The constitution is a personal comfort feature set by the feature setting unit 101 of the remote controller 100, and registers the individual constitution such as cold, hot and atopic constitution. The constitution may be strong or small. Thereby, individual comfort characteristics can be considered in more detail. If the constitutions are not contradictory, a plurality of constitutions may be registered. Thereby, after combining constitution, comfort can be considered.

  The physical condition is a personal comfort characteristic set by the characteristic setting means 101 of the remote controller 100, and registers a temporary physical condition of the individual such as heat and sleepiness. If there is no problem with the physical condition, it is not necessary to set.

  Furthermore, the activity state is a personal comfort feature set by the feature setting means 101 of the remote controller 100, such as taking a bath, doing housework (cleaning, etc.), exercising, after exercising, returning home, eating, resting ( Register the individual's temporary activity status, such as relaxation. If there is no particular need to consider the activity state, it may not be set.

  Also, the constitution may be registered only at the initial setting, and the physical condition or activity state may be registered whenever necessary.

  In this embodiment, the constitution, physical condition, and activity state are collectively managed by the comfort management table 206, but the physical condition and activity state are managed separately from the comfort management table 206 as shown in FIG. May be. In this case, by setting the addresses to the areas where the physical condition and the active state are managed in the physical condition column and the activity state column of the comfort management table 206, respectively, Since it is not necessary to prepare an area for an active state, memory can be reduced. Moreover, since management of physical condition and activity state is necessary only during driving, it may be managed by a volatile memory (not shown). Thereby, it can delete automatically, without performing a deletion process at the time of an operation stop. The storage unit 201 manages the current user.

  FIG. 6 shows an example of the user management table. In the user management table, the unique name of the user (in the room, indoors) and the address of the entry in the comfort management table 206 are managed. If the unique name is not managed in the user management table, the current user is absent. In addition, since management of a user is required only during driving | operation, you may manage by a volatile memory (not shown). Thereby, it can delete automatically, without performing a deletion process at the time of an operation stop.

  Further, as shown in FIG. 4B, a user column may be added to the comfort management table 206 and managed in the comfort management table 206. At this time, by preparing the indoor entry at the top of the table, the process of searching for the entry in the room can be shortened when changing from the driving suitable for the individual comfort to the driving suitable for the indoor comfort. Is possible. When the user column of all entries is OFF, the current user is absent.

[Biometric information registration / comfort feature registration]
The biometric information registration process and the comfort feature registration process will be described.
When the control unit 208 receives the biometric information acquisition request from the remote controller 100, the control unit 208 transmits the biometric information acquisition request to the biometric information acquisition unit 207. When the biometric information acquisition unit 207 receives a biometric information acquisition request from the control unit 208, the biometric information acquisition unit 207 acquires biometric information and transmits a biometric information setting request to the storage unit 201.

[Biometric information registration process (biological information acquisition means: air conditioner)]
FIG. 26 shows a biometric information registration process flow in the storage unit 201. When the storage unit 201 receives the biometric information setting request from the biometric information acquisition unit 207, the storage unit 201 confirms an empty entry in the comfort management table 206. If there is no empty entry (NO in S2601), an error response is returned to the biometric information acquisition unit 207, and the process is terminated (S2605). If there is an empty entry (YES in S2601), it is confirmed whether the same biometric information has already been registered in the comfort management table 206. If the same information is registered (YES in S2602), an error response is returned to the biometric information acquisition unit 207, and the process ends (S2605). If the same information is not registered (NO in S2602), biometric information is set in the empty entry in the comfort management table 206 (S2603), and the entry number is returned to the biometric information acquisition unit 207 (S2604).

  The biological information acquisition unit 207 returns a response from the storage unit 201 to the control unit 208. Upon receiving an error response from the biometric information acquisition unit 207, the control unit 208 transmits a registration failure notification to the remote controller 100 via the communication unit 300. When the entry number is received from the biological information 207, the entry number is transmitted to the remote controller 100 via the communication unit 300.

  When the control unit 208 receives the comfort feature setting request from the remote controller 100, the control unit 208 designates the entry number in the storage unit 201 and transmits the comfort feature setting request.

[Comfort registration process]
FIG. 27 shows a comfort feature registration process flow of the storage unit 201.
When the storage unit 201 receives the comfort feature setting request from the control unit 208, the storage unit 201 checks the validity of the entry number. If the entry number is not appropriate, such as the entry number does not exist in the comfort management table 206 (NO in S2701), an error response is returned to the control unit 208, and the process ends (S2703). If the entry number is appropriate (YES in S2701), various information is set in the designated entry of the comfort management table 206, and a success response is returned to the control unit 208 (S2702).

  In this embodiment, the error check process for the comfort feature information to be registered is performed by the remote controller 100 and is not performed by the comfort feature registration process. However, it may be performed by the comfort feature registration process. It may be implemented by either.

  Upon receiving an error response from the storage unit 201, the control unit 208 transmits a registration failure notification to the remote controller 100 via the communication unit 300. At this time, the storage unit 201 is requested to delete the biological information set in the storage unit 201. On the other hand, when a success notification is received from the storage unit 201, a success response is transmitted to the remote controller 100 via the communication unit 300.

[Biometric information registration processing / comfort characteristic registration processing (biological information acquisition means: remote controller)]
The biometric information registration process and the comfort feature registration process when biometric information is acquired by the controller 100 are shown below. This can be achieved by substantially the same processing except that the air conditioner 200 does not acquire biological information and the type of request message from the remote controller is different.

  When the control unit 208 receives the biometric information setting request from the remote controller 100, the control unit 208 sets the biometric information specified in the biometric information setting request as a request and transmits the biometric information setting request to the storage unit 201. The storage unit 201 performs biometric information registration processing shown in FIG.

  Upon receiving an error response from the storage unit 201, the control unit 208 transmits a registration failure notification to the remote controller 100 via the communication unit 300. When the entry number is received from the storage unit 201, the comfort feature setting request and the unique name specified in the biometric information setting request and the entry number are specified, and the comfort feature setting request is transmitted to the storage unit 201. The storage unit 201 performs the comfort feature registration process shown in FIG.

  Upon receiving an error response from the storage unit 201, the control unit 208 transmits a registration failure notification to the remote controller 100 via the communication unit 300. At this time, the storage unit 201 is requested to delete the biological information set in the storage unit 201. On the other hand, when a success notification is received from the storage unit 201, a success response is transmitted to the remote controller 100 via the communication unit 300.

[Human body detection processing]
FIG. 28 shows a human body detection process flow.
The human body detection unit 202 receives the instruction from the control unit 208 and periodically detects the number of people in the room (S2801). If no occupant can be detected in the room (YES in S2802), the human body detection unit 202 sets “absent” in the user management table of the storage unit 201 (S2803). When a room occupant can be detected in the room, it is determined whether the number of persons is one or more. When the number of detected persons is plural (NO in S2802 and YES in S2804), the human body detection unit 202 sets “indoor” in the user management table of the storage unit 201 (S2805). It should be noted that when “absent” and “indoor” are set, it is not necessary to perform overwriting if the same setting has already been made. When the number of detected persons is one (NO in S2802, NO in S2804, and YES in S2806), the user determination unit 203 is requested to make a user determination (S2806), and the control index determination unit 204 is detected. Is transmitted (S2809). Thereby, a change of the user can be detected.

  On the other hand, when the occupant cannot be detected in the room (YES in S2802) and when the number of detected persons is plural (NO in S2802 and YES in S2804), the detection result is compared with the previous detection result. (S2807).

  FIG. 29 shows a detection result comparison processing flow in the human body detection flow shown in FIG. It is assumed that “absent” is set in the user management table of the storage unit immediately after activation.

  The human body detection unit 202 compares the detected result with the current user managed by the user management table of the storage unit 201. If the detection result is “absent” and the current user is a room or a specific individual (YES in S2901 and YES in S2902), it is determined that the occupant in the room has changed to absent (S2903). ). If the detection result is “multiple people” and the current user is absent or a specific individual (NO in S2901 and YES in S2905), it is determined that the number of people in the room has changed to multiple people. (S2906). In other cases, it is determined that there is no change in the room occupants (S2904).

  When it is determined that the number of persons has changed from the previous time as a result of the detection result comparison process (YES in S2808), the human body detection unit 202 transmits the detection result to the control index determination unit 204 (S2809). As a result of the detection result comparison process, when the number of persons from the previous time has not changed (NO in S2808), the process ends. However, the detection result is transmitted to the control index determination unit 204 only at the start of operation regardless of the change from the previous time.

  The human body detection means may be a means capable of detecting the number of people in the room at least in a non-contact manner, such as a pyroelectric infrared sensor, an infrared sensor such as a thermopile, an image sensor such as a CMOS image sensor or a CCD image sensor. That's fine.

[User judgment processing]
FIG. 30 shows a user determination processing flow.
When the user determination unit 203 receives a request for determining the current user from the human body detection unit 202, the biometric information acquisition unit 207 acquires biometric information of the occupant (S3001), and the comfort management of the storage unit 201 is performed. The biometric information of the entry managed in the table 206 is compared. If there is an entry with matching biometric information (YES in S3002), the unique name of the matching entry in the comfort management table 206 is set in the user management table of the storage unit 201 (S3003), and the control index determination unit 204 is set. The detection result of “match” is notified (S3004). If there is no entry with matching unique information (NO in S3002), “indoor” is set in the user management table of the storage unit 201 (S3005), and the detection result of “mismatch” in the control index determination unit 204 is set. Is notified (S3006). In addition, you may determine that it is inconsistent when all the results obtained by comparing the biometric information multiple times are different.

[Control index determination processing]
When the detection result is notified from the human body detection unit 202, the control index determination unit 204 determines a control index for performing air conditioning.

  The control index determination unit 204 determines the control index based on information from other than the human body detection unit 202, for example, a detection result from a sensor that detects indoor environmental conditions such as a room temperature sensor and a humidity sensor. The detection results of the human body detection unit 202 and the detection results of the air-conditioned space detection unit 210 will be described specifically.

  FIG. 31 shows a control index determination processing flow for determining a control index based on the detection result of the human body detection means 202.

  When receiving the detection result from the human body detection unit 202, the control index determination unit 204 calculates a control target value according to the comfort in the room if the detection result is absent or there are a plurality of persons (YES in S3101) (S3102). . When the detection result from the human body detection unit 202 is one person (NO in S3101), the determination result of the user determination unit 203 is confirmed. If the determination result of the user determination unit 203 is “match” (YES in S3103), the control correction value is determined according to the individual comfort set in the user management table of the storage unit 201, and the control target value Is set (S3104). On the other hand, when the determination result of the user determination unit 203 is “mismatch” (NO in S3103), the control target value is calculated according to the comfort in the room (S3102).

  Note that the control target value corresponding to the comfort in the room is a desired set temperature (room temperature) that is normally set by the remote controller 100, but is not limited to the suction temperature, the blow-out temperature, the outside air temperature, the humidity, etc. from each sensor. It is also possible to calculate the indoor comfort using information. In addition to this, it may be calculated based on information such as the number of people in the room and the floor plan. In addition, it is possible to use PMV (Predicted Mean Vote) that is a comfort index based on the thermal balance equation of the human body and the individual constitution and physical condition information registered in the comfort management table 206. .

  Further, the control correction value according to the individual comfort is calculated by referring to the personal constitution / physical condition / activity state managed by the user management table of the storage unit 201 from the comfort management table 206. The control correction value is determined such that, for example, when it is hot, the cooling temperature is decreased by 1 degree with respect to the control target value, and when the person is cold, it is increased by 1 degree with respect to the control target value. In addition, although the relationship between each comfort characteristic and a correction degree is memorize | stored in the memory | storage part 201, the example is shown in FIGS.

In the example shown in FIGS. 32 to 34, the room temperature stability condition is set as follows.
・ Cooling conditions: Temperature 28 ℃, humidity 50% RH
・ Heating conditions: Temperature 20 ℃, humidity 50% RH
In addition, the appropriate temperature is considered in consideration of comfort and energy saving. The reason why the appropriate humidity is set to 50% RH is that the virus easily propagates when the humidity falls below 30% RH, and it has an adverse effect on the skin and throat. This is because when the humidity exceeds 60% RH, discomfort increases and mold and mites are likely to occur. Further, the control amount is shifted in a direction in which the human body becomes comfortable, and energy saving is not always achieved.

  Furthermore, in the example shown in FIGS. 32 to 34, the temperature control for shifting the room temperature detected by the room temperature sensor and the humidity control for shifting the room humidity detected by the humidity sensor are performed simultaneously. Either one may be performed. 32 to 34, the reason for shifting the control target value is described. This is for easy understanding of the control correction, and the reason for shifting the control target value is the comfort management table 206. Is not recorded.

  In addition, when the determination result of the user determination unit is absent or there are a plurality of persons, it has been described that the control target value is calculated according to the comfort of the room, but in the absence, the operation with the control target value with reduced power consumption is described. May be performed. There is no occupant, so even if you drive with reduced power consumption, you will not feel uncomfortable, and the operation is automatically switched when you enter the room. realizable.

  Next, a method for determining a control index based on the detection process of the air-conditioned space detection unit 210 and the detection result will be described with reference to FIGS. The air-conditioned space detection means 210 is a camera that takes an image.

  FIG. 35 schematically shows a method of photographing an interior from the position of the indoor unit 200 and detecting an obstacle, and is a room having walls on the front and left and right. FIG. 35 (a) shows that a person 3206 is present in the room, 3201 is a left side wall, 3202 is a front wall, 3203 is a right side wall, and 3204 is a door for entering and exiting the room, as viewed from the air-conditioned space detecting means 210. . Now, since the table 3205 is placed in the room, the person 3206 can move in the space surrounded by the left side wall 3201, the front wall 3202, and the right side wall 3203, but since there is the table 3205, a part of the table 3205 is Only around it can move. FIG. 35 (b) is FIG. 35 (a), and the history of the place where the person 3206 can walk is stored in the storage unit 201. The history when walking all the places where the person 3206 can walk is a blackened range, and this range becomes a movable place 3207. Conversely, it can be determined that there is an obstacle other than the movable place 3207.

  FIG. 36 schematically shows a method of detecting opening and closing of a door, and is the same room as FIG. FIG. 36A shows a state where the door 3204 is closed, and FIG. 36B shows a state where the door 3204 is opened. When the door 3204 is opened, a part of the door 3204 that is in the closed state becomes invisible, and the outside of the room can be seen at the position where the door 3204 has been located so far, so that the image when the door 3204 is closed is displayed. And the image in which the door 3204 is opened, a difference occurs in the portion in which the door 3204 is opened, and it can be detected that the door 3204 is opened. If images are taken at regular intervals, the time until the door 3204 is next closed can also be detected.

  FIG. 37 schematically shows a method for detecting the position of a person, and is the same room as in FIG. When the room is viewed from the position of the indoor unit 200, when a person stands near the indoor unit 200, the person appears in the lower position of the screen as in the person 3206 (a), and the person is near the indoor front wall. When standing, it appears in the upper position of the screen like person 3206 (c), and when a person stands in the center of the room, people 3206 (a) and 3206 (c) like person 3206 (b) It is reflected in the position between. In this way, it is possible to detect where the person 3206 is based on the position on the screen.

  Further, the distance from the camera to the person may be detected not by the position on the screen but by the size on the screen. When the room is viewed from the position of the indoor unit 200, when a person stands near the indoor unit 200, the person appears large on the screen like the person 3206 (a), and the person is near the front wall of the room. When standing, it looks small like a person 3206 (c), and when a person stands in the center of the room, it becomes an intermediate size between the person 3206 (a) and the person 3206 (c) like a person 3206 (b). . Therefore, the distance to the person can be obtained by creating a table as shown in FIG. 38 indicating the size on the image and the distance from the camera to the person in advance.

  FIG. 39 schematically shows a method of detecting a window. 3501 is a window, 3502 (a) is a curtain hung on the left side of the window 3501, and 3502 (b) is hung on the right side of the window 3501. It is a curtain. Normally, the curtains 3502 (a) and 3502 (b) opened in the daytime are stopped toward the left and right of the window 3501 (FIG. 39 (a)), and are closed toward the center from the left and right at night. For example, the movement when the left curtain 3502 (a) is closed starts from the state of FIG. 39 (a) and gradually moves toward the center as shown in FIG. 39 (b). Thus, the center of the window 3501 is reached. There is a similar movement in the right curtain 3502 (b). Also, when opening the curtain 3502 (a), the movement opposite to that at present, that is, from the state of FIG. 39 (c), is moved to the left as shown in FIG. 39 (b), as shown in FIG. 39 (a). Can be stopped at the left end. By capturing such movement with a camera, the position where the window is located can be determined.

  FIG. 40 schematically shows a method for detecting the amount of activity of a person. A person A 3601 and a person B 3602 are in the same room as in FIG. In FIG. 40, (a), (b), and (c) are images taken at fixed time intervals, for example, every second, and the person A3601 moves to the left and right while three images are taken. Yes. The broken line (A) is the center of the person 3601 in FIGS. 40A and 40C, the broken line (B) is the center of the person 3601 in (b), and the broken line (C) is (a), (b). , (C) represents the center of person B3602. As indicated by the arrow 3603, the person A 3601 moves to the right by the width of the arrow 3603 at the time (b) for 1 second from the time point (a), and further by the width of the arrow 3606 at the time (c) at 1 second later. It is moving to the left. During this period from (a) to (c), the person B 3602 hardly moves. In this way, by comparing images at regular intervals, you can understand the movement of a person, and the amount of activity of the person, for example, walking around the room or exercising, is reading a book, TV You can see whether the amount of activity is small.

  FIG. 41 shows a control index determination processing flow for determining a control index based on the detection result of the air-conditioned space detection means 210.

  The temperature is a control target value corresponding to the comfort in the room, and the control index determined based on the detection result of the air-conditioned space detection means 210 is the air volume and the wind direction.

  The air-conditioned space detection means 210 confirms the opening / closing of the indoor door, and if the door is open (YES in S3601), sets the air volume stronger and the front of the wind direction door as a control index (S3602). If the door is closed (NO in S3601) and the person is near the window (YES in S3603), the correction value for the air conditioning temperature window is set (S3604).

  When a person is near the window, it is affected by solar radiation through the window during cooling, so the temperature of the place where the person is is corrected to a predetermined temperature (for example, 1 ° C.) lower than the temperature set by the remote controller 100, During heating, since it is affected by cold radiation through the window, it is preferable to correct the temperature of the place where the person is present by a predetermined temperature (for example, 1 ° C.) higher than the temperature set by the remote controller 100. Is set as the correction value for windows. If no person is near the window, nothing is done (NO in S3603).

  Next, the activity amount of the person is detected (S3605), and the activity amount correction is set according to the detected activity amount (S3606). Specifically, for example, two threshold values (a first threshold value and a second threshold value larger than the first threshold value) are set for the human activity amount, and the case where the human activity amount is smaller than the first threshold value is expressed as “ “Small amount of activity (for example, at rest)”, “active amount” when the activity amount of the person is greater than or equal to the first threshold and less than the second threshold, and “ “Large amount of activity”. In the case of “small amount of activity”, the body temperature is lowered without being noticed by the person, so the temperature of the place where the person is located is corrected higher than the temperature set by the remote controller 100 (for example, 1 ° C.) during cooling. In the case of “high amount of activity”, the body temperature rises, and therefore the temperature of the place where the person is present is corrected to be lower than the temperature set by the remote controller 100 by a predetermined temperature (for example, 1 ° C.). Such a correction value is set as an activity amount correction value, and if it is “active amount”, no correction is made (NO in S3605). It should be noted that the amount of activity correction can be performed during heating as well as during cooling.

  Further, when the person is far away (YES in S3607) and there is an obstacle in front of the person (YES in S3608), the front of the strong air volume / wind direction obstacle is set as the control index (S3609). If there is no obstacle, the control index is set to increase the air volume and to be in front of the wind direction (S3610). If the person is not far away (NO in S3607) and is at an intermediate position (YES in S3611), and there is an obstacle in front of the person (YES in S3612), the air volume is increased and the front of the wind direction obstacle is set as a control index. (S3613). If the person is not far away (NO in S3607) and is at an intermediate position (YES in S3611) and there is no obstacle in front of the person (S3614), the air flow is weakened and the wind direction is in front of the person as a control index. If the person is not far away (NO in S3607) and is not in the middle position (NO in S3611), the person is near the indoor unit 200, so the air conditioning around the person is immediately comfortable even if the air volume is weak Therefore, the air volume of the control index is weakened, and the wind direction of the control index is human side so that direct wind is not applied (S3615).

  Note that the wind direction control is swingable to the indoor unit 200 and the angle of an up / down air direction change blade (not shown) that is attached to the indoor unit 200 so as to be swingable and changes the conditioned air blown from the indoor unit 200 up and down. The air conditioning control unit 205 controls the angle of left and right air direction changing blades (not shown) that change the air conditioning air blown from the indoor unit 200 to the left and right. In addition, the left and right wind direction changing blades usually have at least two sets of left and right wind direction changing blades that are independently angle-controlled, and “wind direction: human side” means the angle of the two sets of left and right wind direction changing blades This is control that delivers conditioned air to both sides of a person with a predetermined angle (for example, several degrees) shifted to the right and left. On the other hand, the air volume control is performed by controlling the rotation speed of an indoor fan (not shown) provided in the indoor unit 200 by the air conditioning control unit 205.

  As described above, the control index is calculated according to one or more of the position of the obstacle, the position of the person, the opening and closing of the door, the position of the window and the person detected by the air-conditioned space detection unit 210, and It is possible to provide comfortable air conditioning for people in the room according to the situation.

  In addition, although the explanation of judging the size of the obstacle etc. is not made this time, for example, the obstacle in front of the person is long horizontally, and even if the wind is sent in front of the obstacle, the air around the person is heated, for example When it is sometimes impossible to warm up, it is necessary to control such as sending wind over obstacles and next to people.

  The control index is determined based on the detection result of the human body detection means by determining a control correction value according to the individual comfort set in the registered comfort management table and setting a control target value. It is also possible to determine the control target value by combining the method and the method of setting the control target value according to the position of the person, the position of the obstacle, and the opening and closing of the door based on the detection result of the conditioned space detection means. is there. By combining the two methods, for example, when a person who is set to be hot is in the center of the room, the set temperature is reduced by 1 degree because it is hot, and the air volume is increased because it is hot and away from the indoor unit. It is possible to make a more comfortable air-conditioning by making a composite determination of a person's preference, where the person is, and the positional relationship with an obstacle.

[Air conditioning system]
An outline of the operation of the air conditioning system including the remote controller 100 and the indoor unit 200 configured as described above will be described.
Here, a description will be given assuming that the air conditioning system is installed in a family of four people (family A to D).

[Initial startup]
When the control unit 208 of the indoor unit 200 receives an operation start signal from the remote controller 100 via the communication unit 300, the control unit 208 requests the human body detection unit 202 to detect a person in the room. It is assumed that “absent” is set as an initial value in the user management table of the storage unit 201. The human body detection unit 202 performs human body detection processing and sets the current user in the user management table of the storage unit 201. Note that the detection result is transmitted to the control index determination unit 204 only at the start of operation regardless of the previous detection result. At this time, when the occupant cannot be detected or when the occupant detects a plurality of occupants, the control index determination unit 204 calculates a control target value according to the comfort in the room, and the control unit 208 requests the air conditioning control unit 205 to control the air conditioner. The air conditioning control unit 205 controls the air conditioner according to the index set by the control index determining unit 204.

  On the other hand, when the detected occupant is one person, the human body detection unit 202 requests the user determination process from the user determination unit 203. Here, since the air conditioner is initially activated and no entry is registered in the user management table of the storage unit 201, the user determination unit 203 causes the control index determination unit 204 to perform the user determination process. Send “mismatch”. Since the determination result is inconsistent, the control index determination unit 204 calculates a control target value according to the comfort in the room, and the control unit 208 requests the air conditioning control unit 205 to control the air conditioner. The air conditioning control unit 205 controls the air conditioner according to the index set by the control index determining unit 204.

  In addition, since the entry is not registered in the comfort management table 206 of the storage unit 201 at the start of the initial operation, it has been described that the entry is not registered. However, as the human body detection process is periodically repeated, the entry is updated. Once registered, air conditioning control according to individual comfort can be realized. In addition, when a new comfort feature setting / change / deletion occurs, the human body detection process may be performed without fail. This makes it possible to provide air conditioning that is always adapted to the latest comfort of the individual.

[Comfort feature setting]
The family A operates the remote controller 100 to set the comfort characteristics. In the present embodiment, it is assumed that the remote controller 100 is provided with a feature setting button alone. In addition, the indoor unit 200 includes a CCD camera as a biological information acquisition unit.
Family A presses the feature setting button to start the feature setting process. For initial registration, a unique name is not set in the storage unit of the remote controller 100, and the control unit 105 of the remote controller 100 performs a new feature setting process. The control unit 105 displays a message requesting the setting of the unique name and a Japanese syllabary on the display unit 104. The family A operates the temperature setting button of the operation button group 102 to select a character, sets it with the setting button, and inputs a name. When the input is completed, the temperature setting button of the operation button group 102 is operated on the “decision” menu, the cursor is set, and the input process is ended.

  When the control unit 105 detects the end of the setting of the unique name, the control unit 105 performs an error check on the input unique name, and if there is no error, stores the unique name in the temporary memory of the storage unit 103 and ends the process. Next, the control unit 105 performs a comfort feature setting process. The control unit 105 displays on the display unit 104 a message requesting the setting of comfort characteristics and choices of constitution and physical condition. The family A operates the temperature setting button of the operation button group 102 to select the constitution / physical condition and sets it with the setting button. Here, the constitution is not set, and “heat / cold” is set as the physical condition. When the setting is completed, the temperature setting button of the operation button group 102 is operated on the “decision” menu to place the cursor, and the setting process is ended. When detecting the end of the setting process, the control unit 105 checks whether the constitution and physical condition are set. Since the constitution was not set, the code indicating the standard as the constitution was saved in the temporary memory of the storage unit 103, while the code indicating “heat / cold” was set in the temporary memory of the storage unit 103. The process ends.

  When the comfort feature setting process ends, the control unit 105 performs a biological information setting process. The control unit 105 transmits a biometric information acquisition request signal to the control unit 208 of the indoor unit 200 via the communication unit 300. When the control unit 208 of the indoor unit 200 receives a biometric information acquisition request signal from the remote controller 100 via the communication unit 300, the control unit 208 performs biometric information acquisition processing. At this time, a message indicating that biometric information is being set is displayed on the display unit 104 of the remote controller 100. The control unit 208 of the indoor unit 200 requests the biometric information acquisition unit 207 to acquire biometric information. The biometric information acquisition unit 207 takes an image of the family A and requests the storage unit 201 to set biometric information. When the biometric information setting is successful, the storage unit 201 returns the entry number of the comfort management table 206. The biometric information acquisition unit 207 returns the entry number to the control unit 208, and the control unit 208 transmits the entry number to the control unit 105 of the remote controller 100 as a biometric information acquisition response via the communication unit 300. When receiving the biometric information acquisition response from the control unit 208 of the indoor unit 200 via the communication unit 300, the control unit 105 of the remote controller 100 stores the entry number in association with the unique name of the family A in the storage unit 103. Next, the control unit 105 transmits a comfort feature and unique name setting request signal to the control unit 208 of the indoor unit 200 by specifying an entry number via the communication unit 300. When the control unit 208 of the indoor unit 200 receives a comfort feature and a unique name setting request signal from the remote controller 100 via the communication unit 300, the control unit 208 performs comfort feature registration processing. The control unit 208 specifies an entry number in the storage unit 201 and requests setting of the comfort feature and the unique name. When the setting is successful, the storage unit 201 returns a setting response. When the control unit 208 receives the comfort feature setting response from the storage unit 201, the control unit 208 transmits the comfort feature setting response to the control unit 105 of the remote controller 100 via the communication unit 300. When the control unit 105 of the remote controller 100 receives the comfort characteristic setting response from the control unit 208 of the indoor unit 200 via the communication unit 300, the control unit 105 displays a message indicating that the setting has been completed on the display unit 104. The family A operates the temperature setting button of the operation button group 102 on the “end” menu, aligns the cursor, and ends the setting process.

Similarly, it is assumed that the families C to D operate the remote controller 100 and set the comfort characteristics as shown in the comfort management table of FIG.
Family A: Atsushi, Family B: Kayoko, Family C: Daddy, Family D: Mom

[Switching during operation]
The control unit 208 of the indoor unit 200 periodically requests the human body detection unit 202 to detect a person in the room after the start of operation.

It is assumed that the family A is currently in the room and that comfortable driving in accordance with the family A is being performed.
<1 person-> multiple people>
Here, it is assumed that family B has entered the room. When detecting that the number of people in the room has changed from one to a plurality of persons in the human body detection process, the human body detection detection unit 202 sets the current user of the storage unit 201 to “indoor” and determines the detection result as a control index. To the unit 204. When the control index determination unit 204 receives the detection result indicating that the human body detection unit 202 has changed to a plurality of persons, the control index determination unit 204 cancels the comfortable driving in accordance with the family A and re-determines the control index according to the comfort in the room.

<Multiple → 1>
On the other hand, suppose that family A leaves. When detecting that the number of people in the room has changed from a plurality of people to one in the human body detection process, the human body detection detection unit 202 transmits the detection result to the control index determination unit 204. Further, the user determination unit 203 is requested to determine the user. The user determination unit 203 performs user determination processing and detects that the image acquired by the biometric information acquisition unit 207 matches the image that is the biometric information of the family B managed by the comfort management table 206 of the storage unit 201. Then, the family B is set in the user management table of the storage unit 201 and the determination result “match” is transmitted to the control index determination unit 204. The control index determination unit 204 re-determines the control index according to the comfort of the family B from the determination result of the human body detection means and the determination result of the user determination unit 203.

<1 person-> multiple people (others)>
Suppose that there was a family visitor there. When detecting that the number of people in the room has changed from one to a plurality of persons in the human body detection process, the human body detection detection unit 202 sets the current user of the storage unit 201 to “indoor” and determines the detection result as a control index. To the unit 204. When the control index determination unit 204 receives a detection result indicating that the human body detection unit 202 has changed to a plurality of persons, the control index determination unit 204 cancels the comfortable driving in accordance with the family B, and re-determines the control index according to the comfort in the room.

<Multiple (others) → absent>
Here, it is assumed that the family B and the customer leave together, and there are no people in the room. When detecting that the number of people in the room has changed from a plurality of persons to the absence in the human body detection process, the human body detection detection unit 202 sets the current user of the storage unit 201 to “absent”, and sets the detection result as a control index determination unit. 204. When the control index determination unit 204 receives the detection result indicating the absence from the human body detection unit 202, the control index determination unit 204 re-determines the control index according to the comfort in the room.

<Absence-> 1 person>
Suppose family C enters the room. When detecting that the occupant has changed from being absent to one person in the human body detection process, the human body detection detection unit 202 transmits the detection result to the control index determination unit 204. Further, the user determination unit 203 is requested to determine the user. The user determination unit 203 performs user determination processing and detects that the image acquired by the biometric information acquisition unit 207 matches the image that is the biometric information of the family C managed by the comfort management table 206 of the storage unit 201. Then, the family C is set in the user management table of the storage unit 201 and the determination result of “match” is transmitted to the control index determination unit 204. The control index determination unit 204 re-determines the control index according to the comfort of the family C from the determination result of the human body detection means and the determination result of the user determination unit 203.

<1 person → absent → 1 person (others)>
Here, it is assumed that the family C leaves and a visitor enters the room. First, when the family C leaves, the human body detection detecting unit 202 sets the current user of the storage unit 201 to “absent” when detecting that the occupant has changed from one person to the absence in the human body detection process. Then, the detection result is transmitted to the control index determination unit 204. When the control index determination unit 204 receives the detection result indicating the absence from the human body detection unit 202, the control index determination unit 204 re-determines the control index according to the comfort in the room.

  Next, when detecting the arrival of a guest, the human body detection detecting unit 202 transmits the detection result to the control index determination unit 204 when detecting that the occupant has changed from being absent to one in the human body detection process. Further, the user determination unit 203 is requested to determine the user. The user determination unit 203 performs user determination processing, detects that the image acquired by the biometric information acquisition unit 207 does not match any entry in the comfort management table 206 of the storage unit 201, and uses the user of the storage unit 201. “Indoor” is set in the management table, and the determination result of “mismatch” is transmitted to the control index determination unit 204. The control index determination unit 204 re-determines the control index according to the comfort in the room from the determination result of the human body detection means and the determination result of the user determination unit 203.

[When stopped]
When receiving the operation stop signal from the remote controller 100 via the communication unit 300, the control unit 208 of the indoor unit 200 resets the physical condition information of each entry in the comfort management table 206 of the storage unit 201. According to such a configuration, it is possible to reduce the trouble of canceling the setting by the operator. In addition, when the setting is forgotten to be cancelled, temperature correction is not performed in consideration of comfort due to an incorrect physical condition at the start of the next operation.

  The storage unit 201 may manage the relationship between each physical condition and the effective period, set an effective period when setting the physical condition, and automatically reset the physical condition information when the effective period expires. According to such a configuration, it is possible to automatically return to a normal state without disturbing the operator's hand with respect to temporary changes in physical condition. In addition, the relationship between each physical condition managed by the storage unit 201 and the effective period may be registered in the air conditioner with a fixed value in advance, or may be changeable by the operator. According to such a configuration, it is possible to provide comfort related to physical condition that is more tailored to the individual operator.
