Summary of the Invention

Problems to be Solved by the Invention

[0004] A user may sometimes feel a plurality of physical conditions simultaneously, such as "heavy head" and "dry throat". In Patent Document 1, it is not assumed that a plurality of physical conditions are input simultaneously. Also, the user's physical condition is not always improved only by temperature and humidity.

[0005] The present invention has been made in view of the above problems, and an object thereof is to realize an indoor environment that alleviates the symptoms by controlling a plurality of devices when a user inputs a plurality of symptoms.

Means for Solving the Problems

[0006] (1) The indoor environment adjustment system of the present invention comprises a plurality of devices for adjusting the indoor environment of a living room, a user terminal for receiving input from a user, and a controller for controlling the operation of the plurality of devices. The controller performs the following: a first operation process for starting the devices based on a first condition which includes predetermined operation content for each of the plurality of devices; a first acquisition process for acquiring a second condition which includes predetermined operation content for the first symptom information and a third condition which includes operation content for the second symptom information, based on at least first symptom information and second symptom information acquired from the user terminal; and a second operation process which, on the condition that it is determined that the second and third conditions cannot be executed simultaneously for at least one of the plurality of devices, causes that device to operate with the operation content that causes a greater change to the indoor environment from either the second or third condition.

[0007] The user can input multiple symptoms they are experiencing into the user terminal. The controller controls the indoor environment by operating multiple devices based on the operating conditions corresponding to these symptoms. If the user has entered two or more symptoms, and there are devices that cannot simultaneously execute the second and third conditions corresponding to each symptom, the controller operates the device based on the operating condition of the second and third conditions that will cause the greatest change to the indoor environment. This creates an indoor environment that alleviates the user's multiple symptoms.

[0008] (2) The indoor environment adjustment system further includes a sensor for detecting the indoor environment. In the second operation process described above, the indoor environment may be determined based on the detection signal of the sensor.

[0009] It can accurately detect the indoor environment. Furthermore, for equipment with defined operating conditions that have a range, it can determine whether the second or third condition causes a greater change in the indoor environment.

[0010] (3) In the second operation process described above, the indoor environment may be determined based on the first condition described above.

[0011] Even without sensors inside the room, the indoor environment can be determined based on the first condition.

[0012] (4) The indoor environment adjustment system further includes memory. The controller may record in the memory the operation details of each device determined in the second operation process as improvement operation conditions indicating improvement to the first symptom information and the second symptom information, provided that it does not acquire the first symptom information and the second symptom information from the user terminal within a predetermined time after executing the second operation process.

[0013] The operating conditions that improve the user's symptoms are recorded in memory.

[0014] (5) The controller may, provided that it has obtained the first symptom information and the second symptom information from the user terminal within a predetermined time after executing the second operation process, further execute a third operation process to operate the device that was the subject of the determination in the second operation process with an operation that was not selected from the second and third conditions.

[0015] If the first and second symptom information does not improve under the operating conditions determined in the second operation process, the device is operated under the unselected operating conditions to create an indoor environment that alleviates multiple symptoms of the user.

[0016] (6) The indoor environment adjustment system further includes memory. The controller may record in the memory the operation details of each device determined in the third operation process as improvement operation conditions indicating improvement to the first symptom information and the second symptom information, provided that it does not acquire the first symptom information and the second symptom information from the user terminal within a predetermined time after executing the third operation process.

[0017] The operating conditions that improve the user's symptoms are recorded in memory.

[0018] (7) The controller may, provided that it has obtained the first symptom information and the second symptom information from the user terminal within a predetermined time after executing the third operation process, further execute a fourth operation process in which, for the device whose operation content was not changed from the first condition in the third operation process, it obtains a fourth condition which includes operation content different from the first condition and operates the device according to the fourth condition.

[0019] If the user's multiple symptoms do not improve even when the equipment is operated under conditions 2 and 3, the controller changes the operating conditions of the equipment that have not been changed from condition 1 to create an indoor environment that alleviates the user's multiple symptoms.

[0020] (8) The indoor environment adjustment system further includes memory. The controller may record in the memory the operation details of each device determined in the fourth operation process as improvement operation conditions indicating improvement to the first symptom information and the second symptom information, provided that it does not acquire the first symptom information and the second symptom information from the user terminal within a predetermined time after executing the fourth operation process.

[0021] The operating conditions that improve the user's symptoms are recorded in memory.

[0022] (9) The controller may, provided that it has obtained the first symptom information and the second symptom information from the user terminal within a predetermined time after executing the fourth operation process, execute an advice output process to the user terminal which provides advice that is predetermined regarding the first symptom information and the second symptom information.

[0023] When an indoor environment that improves multiple symptoms cannot be achieved under any of the operating conditions, the system can provide advice on user actions.

[0024] (10) In the above-described first acquisition process, on the condition that the improved operation conditions are recorded in the memory, instead of the above-described second operation process, the device may be operated under the improved operation conditions.

[0025] By operating the device under the improved operation conditions in which the user's symptoms have improved in the past, an indoor environment in which a plurality of the user's symptoms are reliably alleviated is realized.

[0026] (11) The controller may update the first condition to the improved operation condition on the condition that the first symptom information and the second symptom information have been acquired from the user terminal a predetermined number of times.

[0027] When a plurality of devices operate under the first condition, when the frequency of occurrence of a plurality of symptoms in the user is high, the first condition for starting the plurality of devices is updated to the improved operation condition. Therefore, it is possible to reduce the user's feeling of symptoms after the plurality of devices are started.

[0028] (12) The controller performs a second acquisition process of acquiring a fifth condition including the operation content of the device for the third symptom information and a sixth condition including the operation content of the device for the fourth symptom information, which are acquired from each of two users within a predetermined time, a calculation process of calculating an index for each of the two users from the predetermined characteristics of the user and the weighting coefficient determined according to the characteristics, a determination process of determining the priority order of the two users according to the magnitude of the calculated index, and a fifth operation process of operating the device with the operation content obtained by combining the fifth condition and the sixth condition according to the determined priority order.

[0029] For the symptoms input by two users, the operation conditions can be combined to operate the device. Thereby, the symptoms of the two users can be improved simultaneously.

Advantages of the Invention

[0030] According to the present invention, when a user inputs multiple symptoms, an indoor environment that alleviates those symptoms is realized through the control of multiple devices. [Brief explanation of the drawing]

[0032] Embodiments of the present invention will be described below with reference to the drawings as appropriate. It should be noted that the embodiments described below are merely examples of how the present invention can be realized, and the embodiments can be modified as appropriate without altering the essence of the invention.

[0033] [Overview of Indoor Environment Control System 1] As shown in Figures 1 and 2, the indoor environment control system 1 is installed in a building 100 such as an accommodation facility or residence, and is a system that adjusts the indoor environment by adjusting the temperature, humidity, ventilation, airborne particles and odors, and illuminance inside the building 100 (indoors) using multiple devices 10. Multiple devices 10 are installed in the building 100. The indoor environment control system 1 controls the operation of the multiple devices 10. The indoor environment control system 1 comprises multiple devices 10, a user terminal 20, a sensor 30, and a control device 40.

[0034] As shown in Figure 1, the living room 50 is an interior space located inside the building 100. The living room 50 is, for example, a living-dining-kitchen (LDK) and is partitioned by an exterior wall 101, an interior wall 102, a ceiling 103, a floor 104, etc. The interior wall 102 separates the living room 50 from the corridor 51. Although not shown in Figure 1, the interior wall 102 is provided with openings and fittings.

[0035] In this embodiment, the multiple devices 10 are a whole-house air conditioning system 11, a humidity control device 12, a ventilation system 13, a radiant air conditioning system 14, an air purifier 15, and dimmable and color-adjustable lighting 16. As shown in Figure 1, openings 105 are located in the ceilings 103 of the corridor 51 and the living rooms 50. A duct 106 is installed in each of the openings 105. The ducts 106 connect each opening 105 to the whole-house air conditioning system 11, the humidity control device 12, and the ventilation system 13 so that air can flow through them. Note that in Figure 1, the illustrations of the whole-house air conditioning system 11, the humidity control device 12, and the ventilation system 13 are simplified, but the whole-house air conditioning system 11, the humidity control device 12, and the ventilation system 13 may each be connected to the living rooms 50 and corridor 51 by independent ducts.

[0036] The whole-house air conditioning system 11 is, for example, an air conditioning unit capable of supplying hot or cold air. The whole-house air conditioning system 11 can supply hot or cold air to the entire interior of the building 100 via ducts 106. The whole-house air conditioning system 11 is located in the space above the ceiling 103 (above the ceiling).

[0037] The humidity control device 12 is, for example, a device capable of humidifying and dehumidifying the air. Like the whole-house air conditioning system 11, the humidity control device 12 humidifies or dehumidifies the entire air inside the building 100 via the duct 106. The humidity control device 12, together with the whole-house air conditioning system 11, is located in the space above the ceiling 103.

[0038] The ventilation system 13 is, for example, a ventilation device that takes in air from outside the building 100 and discharges air to the outside of the building 100. The ventilation device, for example, uses the rotation of a fan to take in outside air through a duct 107 that opens to the outside of the building and supplies air to the inside of the building 100 through a part of the duct 106. The ventilation system 13 also uses the rotation of a fan to draw in air from the inside of the building 100 through a part of the duct 106. The ventilation device 13 discharges the drawn-in air to the outside through a duct 108. The ventilation system 13 may also be a total heat exchanger that performs heat exchange between the outside air taken in from the outside and the air drawn in from the inside to ventilate.

[0039] The radiant air conditioning system 14 is a device that uses radiant heat to raise or lower the temperature of the air in the living room 50. The radiant air conditioning system 14 exchanges heat between the pipes and the air in the living room 50 by circulating hot or cold water through pipes located below the floor 104. Specifically, the radiant air conditioning system 14 is, for example, floor heating or floor cooling located below the floor 104.

[0040] The air purifier 15 is a device that removes dust and particulate matter from the air in a room. The air purifier 15 is installed, for example, in a living room 50 and uses a fan or the like to supply and exhaust air from the living room 50. In the air purifier 15, the supplied air is exhausted into the living room 50 after passing through a filter (not shown).

[0041] The dimmable and color-tunable lighting 16 is a device that can change the color and brightness of the lighting. The dimmable and color-tunable lighting 16 is, for example, an LED light. The dimmable and color-tunable lighting 16 is installed on the ceiling of the living room 50. The dimmable and color-tunable lighting 16 is color-tuned by the emission of LED chips corresponding to each color. In addition, the dimmable and color-tunable lighting 16 is dimmed by adjusting the emission interval of the LED chips.

[0042] The user terminal 20 is, for example, an information and communication terminal such as a smartphone, tablet, or personal computer. The user terminal 20 is capable of receiving various inputs regarding the operation of multiple devices 10. For example, the user terminal 20 receives input from a user staying in a room 50, such as instructions to start and stop each device 10, as well as instructions to adjust temperature, humidity, wind direction, and airflow. In this embodiment, the user terminal 20 also receives input from a user staying inside the building 100 regarding symptoms they are experiencing. As shown in Figure 2, the user terminal 20 includes a display unit 21, an input unit 22, a transmitting / receiving unit 23, and a SOC (system on chip) 24. Note that multiple user terminals 20 may be provided to accommodate multiple users staying in the building 100.

[0043] The display unit 21 is, for example, a display. The display unit 21 is capable of displaying various information transmitted from the CPU, which will be described later. The display unit 21 can also display various information about multiple devices 10, as well as an input screen for entering symptoms.

[0044] The input unit 22 is, for example, a touch sensor positioned on top of the display. The input unit 22 may be, for example, a touch sensor that outputs a change in the capacitance of the sensor, which changes due to the user's finger touching the display. The input unit 22 may have a controller that calculates coordinates on the display unit 21 from the change in capacitance.

[0045] The transmitting / receiving unit 23 is a communication interface for LAN devices, short-range communication devices, etc. The transmitting / receiving unit 23 is connected to the control device 40 wirelessly or by wire. The transmitting / receiving unit 23 transmits and receives various types of data to and from the control device 40.

[0046] SOC24 is, for example, an integrated circuit that combines a CPU and memory. SOC24 controls the input unit 22 and the display unit 21. For example, SOC24 acquires input data indicating the user's input content entered into the input unit 22, and displays display data indicating the content to be displayed on the display unit 21.

[0047] Sensor 30 is installed in the living room 50 and the corridor 51. Sensor 30 can measure, for example, the black globe temperature, room temperature, humidity, and wind speed. Sensor 30 can convert the measured black globe temperature, room temperature, humidity, and wind speed into electrical signals and output them to the control device 40, which will be described later. Sensor 30 includes, for example, a temperature sensor 31, a humidity sensor 32, and a wind speed sensor 33.

[0048] The temperature sensor 31 is, for example, a sensor using a thermistor. Based on the resistance value of the thermistor, which changes with ambient temperature, the temperature sensor 31 outputs the room temperature and black globe temperature of the living room 50 as electrical signals.

[0049] The humidity sensor 32 is, for example, a sensor using a moisture-sensitive material and at least two electrodes. In the humidity sensor 32, for example, the two electrodes are in contact with the moisture-sensitive material. The resistance between the two electrodes changes depending on the amount of moisture absorbed by the moisture-sensitive material. The humidity sensor 32 calculates the humidity in the living room 50 based on the amount of moisture calculated based on the changed resistance. The calculated humidity in the living room 50 is output as an electrical signal.

[0050] The wind speed sensor 33 is, for example, an ultrasonic sensor. The wind speed sensor 33 has a transmitter that emits ultrasonic waves and a receiver that receives the emitted ultrasonic waves. The wind speed sensor 33 calculates the wind speed in the living room 50 based on the propagation time of the ultrasonic waves, which is affected by the wind speed. The wind speed sensor 33 outputs the calculated wind speed as an electrical signal.

[0051] As shown in Figure 1, the control device 40 is communicated via bus or wirelessly with a plurality of devices 10, a user terminal 20, and a sensor 30. The control device 40 is not limited to being inside the building 100, but may be located outside and connected to the user terminal 20 and the sensor 30 via a network. The control device 40 controls its operation based, for example, on instructions from the user terminal 20. The control device 40 comprises a CPU 41 (an example of a controller) and a memory 42.

[0052] The CPU 41 controls the user terminal 20 and multiple devices 10 by, for example, reading and executing various programs and data stored in the memory 42. The CPU 41 also calculates the temperature, humidity, airflow, and PMV (predicted mean vote) of the living room 50 based on the electrical signals output from the sensor 30.

[0053] Here, PMV is a value that takes into account four factors that determine thermal comfort (temperature (°C), humidity (%), wind speed (m / s), and thermal radiation (°C)) plus two factors related to the human body (metabolic equivalent (met) and clothing amount (clo)). When PMV = 0, thermal neutrality is considered to exist. PMV between 3 and -3 indicates human thermal comfort. For example, when PMV > 0, metabolic heat is greater than radiant heat. That is, when PMV > 0, the larger the number, the hotter a person feels. On the other hand, when PMV < 0, radiant heat is greater than metabolic heat. That is, when PMV < 0, the smaller the number, the colder a person feels. Note that PMV is calculated from, for example, the detected values ​​of sensor 30 (temperature, humidity, radiation, and airflow). Activity level is estimated to be seated, for example, since room 50 is an LDK (living room, dining room, kitchen). Clothing amount is estimated based on the current date and temperature. Here, at least one of the activity level and the amount of clothing worn may be entered by the user into the user terminal 20 as an arbitrary value.

[0054] The memory 42 is a ROM, RAM, EEPROM, etc., and is connected to the CPU 41 via a bus for data communication. The CPU 41 controls the operation of multiple devices 10 by executing programs stored in the ROM.

[0055] As shown in Figure 3, the memory 42 stores, for example, operating conditions for operating multiple devices 10. Each operating condition is associated with a specific type of symptom (an example of a second and third condition). The operating conditions include, for example, operating details that describe the operation of each device 10 in response to symptoms reported by the user.

[0056] The operating conditions corresponding to the symptoms are shown in each row corresponding to the symptom names in FIG. 3. The operating conditions include the operation details that define the operation of each of the plurality of devices 10. Specifically, when the symptom is "very tired", the corresponding operating conditions include, as the operation details, the whole-building air conditioner 11 "0 < PMV < 0.5", the radiant air conditioner 14 "ON", and the dimming and color-tuning lighting 16 "warm white 3500K". When the symptom is "heavy head", the corresponding operating conditions include, as the operation details, the whole-building air conditioner 11 "-0.5 < PMV < 0" and the radiant air conditioner 14 "ON". When the symptom is "headache" or "dizziness", the corresponding operating conditions include, as the operation details, the whole-building air conditioner 11 "room temperature difference ±1°C" and the ventilation equipment 13 "strong operation". When the symptom is "inability to concentrate", the whole-building air conditioner 11 "-0.5 < PMV < 0", the radiant air conditioner 14 "ON", the ventilation equipment 13 "strong operation", and the dimming and color-tuning lighting 16 "daylight white 5000K" are included as the operation details. When the symptom is "itchy eyes", the corresponding operating conditions include, as the operation details, the humidifying equipment 12 "humidification 50 - 60%", the air cleaner 15 "strong operation", and the dimming and color-tuning lighting 16 "2000 lm (lumens)". When the symptom is "runny nose / stuffy nose", the corresponding operating conditions include, as the operation details, the humidifying equipment 12 "dehumidification 40 - 50%", the air cleaner 15 "strong operation", and the ventilation equipment 13 "strong operation". When the symptom is "dry throat", the corresponding operating conditions include, as the operation details, the radiant air conditioner 14 "ON", the humidifying equipment 12 "humidification 50 - 60%", and the air cleaner 15 "weak operation". When the symptom is "cough", the corresponding operating conditions include, as the operation details, the humidifying equipment 12 "humidification 50 - 6%0" and the air cleaner 15 "strong operation". When the symptom is "dry face", the corresponding operating conditions include, as the operation details, the radiant air conditioner 14 "ON", the humidifying equipment 12 "humidification 50 - 60% or dehumidification 40 - 50%", and the air cleaner 15 "strong operation". When the symptom is "stuffy head and ears", the corresponding operating conditions include, as the operation details, the radiant air conditioner 14 "ON", the humidifying equipment 12 "humidification 5%0 - 60% or dehumidification 40 - 50%", and the air cleaner 15 "weak operation".When the symptom is "hands get dry", the corresponding operating conditions include the humidity control device 12 "humidify to 50 - 60% or dehumidify to 40 - 50%", and the air purifier 15 "strong operation" as the operation content. In Fig. 3, "-" indicates that the operation corresponding to the symptom has not been determined.

[0057] Also, in the memory 42, a first condition which is the operating condition for the plurality of devices 10 to operate first is recorded. In Fig. 3, the first condition includes the operating content of each device 10 shown in the row located directly below the device name. Specifically, the first condition includes the whole-building air conditioner 11 "-0.5 < PMV < 0.5, room-to-room temperature difference ±1°C", the radiant air conditioner 14 "OFF", the humidity control device 12 "humidity 40 - 60%", the air purifier 15 "OFF", the ventilation equipment 13 "0.5 times / h", and the dimming and color-tuning lighting 16 "white 4000K, 2500 lm (lumens)" as the operation content. Here, the room-to-room temperature difference is, for example, the temperature difference between the corridor 51 and the living room 50. The "0.5 times / h" of the ventilation equipment 13 means that half of the air inside the building 100 is replaced in one hour.

[0058] Also, as will be described later, when the plurality of operating conditions set for the device 10 are ordered with respect to the symptom information reported by the user, the memory 42 records the plurality of operating conditions and the order in which they are set. Also, as shown in Fig. 4, the memory 42 records question information indicating questions that are sent to the user terminal 20 to receive an answer input regarding the user's symptoms. Also, as shown in Fig. 5, for each user, the memory 42 records operation performance information including the symptoms input in the past, the input date and time (input date-time), the operation of the device 10 executed corresponding to the symptoms, a flag indicating improvement of the symptoms, a flag indicating frequently occurring symptoms, and the date and time when the operation of the device 10 was started. Also, the memory 42 records authentication information such as an identifier for identifying the user. Also, the memory 42 records a flag indicating whether the first condition has been updated by other operating conditions.

[0059] Furthermore, memory 42 stores user characteristics (for example, "hypersensitivity," "minor," "allergic," "female," and "18 years of age or older but under 40 years of age," hereinafter also referred to as user information) that have been registered in advance by the user, corresponding to an identifier for identifying the user. Memory 42 also stores weighting coefficients predetermined according to the user characteristics. In addition, memory 42 stores the number of symptoms entered by each user within the most recent predetermined time. For example, memory 42 stores the number of symptoms entered by each user within the most recent 2 hours. Furthermore, when symptom input is received from multiple users, memory 42 stores information about the user who is given priority in setting the operating conditions.

[0060] The question information, for example as shown in Figure 4, is information that allows the user to respond to each symptom name shown in Figure 3. The question information is, for example, information for displaying various symptom names on the user terminal's display, and information that allows the input of the corresponding symptom name to be received from the input unit 22. In this embodiment, the question information is laid out on the display unit 21 of the user terminal 20 so that each symptom and a checkbox for selecting each symptom are arranged side by side. The symptoms corresponding to the checkboxes checked by input to the input unit 22 of the user terminal 20 are transmitted to the control device 40 as symptom information.

[0061] As shown in Figure 5, a flag is a variable that indicates whether a symptom has improved or whether a symptom occurs frequently more than a certain number of times within a certain period. In Figure 5, a flag is indicated, for example, by "○" or "×". Flags are attached to operating conditions that include the symptom entered by the user and the improved behavior. In the following explanation, "setting a flag" means changing the variable to "1", which results in the state indicated by "○". "Removing a flag" or "clearing a flag" means setting the variable to "0", which results in the state indicated by "×". Note that the variables "1" and "○" indicate affirmation of improvement or frequent occurrence. The variables "0" and "×" indicate negation of improvement or frequent occurrence.

[0062] As shown in Figure 5, the operation record information is a log that records the operation details of the device 10 that was actually operated in response to the user's symptoms. The operation record information includes, for example, the user's name, the symptoms entered by the user, the operation details of the device 10 selected for those symptoms, a flag indicating whether the symptoms improved under those operating conditions, a flag indicating whether the symptoms occurred frequently, and the date and time the symptom information was received.

[0063] The identifier is a string that identifies the user who entered the symptoms. The identifier is predetermined for each user. The CPU 41 identifies the user who entered the symptoms by authenticating the user identifier and the password predetermined for each identifier, which are sent from the user terminal 20.

[0064] The weighting coefficients are predetermined, for example, according to information indicating the user's characteristics. Information indicating the user's characteristics is included in the user information pre-registered in the indoor environment adjustment system 1. User characteristics include, for example, "hypersensitivity," "minor," "allergic constitution," "female," and "18 years of age or older but under 40." As weighting coefficients, for example, "1.5" for users with "hypersensitivity," "1.4" for users with "minor constitution," "1.3" for users with "allergic constitution," "1.2" for users with "female" characteristics, and "1.1" for users aged 18 years or older but under 40 are predetermined.

[0065] [Operation of Indoor Environment Control System 1] Next, the operation of the indoor environment control system 1 will be explained with reference to Figures 6 to 21.

[0066] As shown in Figure 6, the CPU 41 performs user authentication (step S1). The user launches an application on the user terminal 20 to operate the indoor environment control system 1. The user enters their user identifier and password into the user terminal 20 and transmits the user identifier and password entered using the application to the control device 40. The CPU 41 of the control device 40 performs user authentication by comparing the identifier and password received from the user terminal 20 with the authentication information recorded in the memory 42. The CPU 41 identifies the user by confirming that the identifier and password match through user authentication and makes it possible to accept inputs from the user terminal 20 to operate the equipment 10.

[0067] The user inputs a device start signal to the user terminal 20 to start multiple devices 10 and sends it to the control device 40. The control device 40 receives the device start signal from the user terminal 20 (step S2). Based on the receipt of the device start signal, the CPU 41 of the control device 40 reads the first condition (see Figure 3) recorded in the memory 42 (step S3) and starts the multiple devices 10 according to the first condition (an example of the first operation process, step S4). The first condition indicates that among the multiple devices 10, the whole-house air conditioning 11, humidity control equipment 12, ventilation equipment 13, and dimmable and color-adjustable lighting 16 will be operated. The radiant air conditioning 14 and air purifier 15 are set to OFF and therefore will not operate. As a result, the indoor environment of the living room 50 becomes the state indicated in the first condition.

[0068] A user in room 50 may experience some discomfort in the indoor environment of condition 1. As shown in Figure 4, the application on the user terminal 20 lists several symptoms, with a checkbox to the left of each symptom. The user checks the checkbox corresponding to the discomfort they feel on the user terminal 20. In Figure 4, the checkbox for "heavy head" is checked, but multiple symptom checkboxes can be checked. After checking the symptoms on the screen shown in Figure 4, the user taps a send button (not shown). This sends symptom information indicating the symptoms checked by the user from the user terminal 20 to the control device 40. Of course, if the user does not experience discomfort in the indoor environment of condition 1, the user does not need to operate the screen shown in Figure 4 on the user terminal 20.

[0069] When CPU 41 receives symptom information (step S5_YES), it reads the operation history information stored in memory 42 and determines whether there are any symptoms that match the user's symptom information. If the operation history information does not contain any symptoms that match the user's symptom information (step S6_NO), that is, if the user's symptom is not a symptom that has been entered before, the process proceeds to step S7. If the operation history information contains any symptoms that match the user's symptom information (step S6_YES), that is, if the user's symptom has been entered at least once in the past, the process proceeds to step S11.

[0070] In step S7, the CPU 41 determines whether or not only one symptom information has been received. If there is only one symptom information (step S7_YES), the process proceeds to step S8. On the other hand, if there are multiple symptom information (step S7_NO), the process proceeds to step S10.

[0071] In step S8, the CPU 41 reads out the operating conditions corresponding to the symptom information from the operating conditions stored in the memory 42 (see FIG. 3) and sets them as the operating conditions (operation content) of the device 10 (step S9). Then, the CPU 41 operates a plurality of devices 10 under the set operating conditions (step S15).

[0072] For example, when the symptom information indicates "feeling heavy-headed", the operating conditions corresponding to "feeling heavy-headed" among the operating conditions shown in FIG. 3 are read out from the memory 42. For "feeling heavy-headed", from the first condition, the operation content of the central air conditioner 11 is changed to "-0.5 < PMV < 0", the operation content of the radiant air conditioner 14 is changed to "ON", and the operation content of the ventilation equipment 13 is changed to "strong operation". For those devices 10 where "-" is shown as the operation content, it indicates that no specific setting has been made for the operation content and the change is arbitrary. For example, the operation content of the device 10 where "-" is shown as the operation content is not changed from the first condition.

[0073] By changing the setting of the central air conditioner 11 from "-0.5 < PMV < 0.5" to "-0.5 < PMV < 0", the central air conditioner 11 operates so that the temperature of the living room 50 decreases. By changing the radiant air conditioner 14 from "OFF" to "ON", the living room 50 is warmed from the floor 104. By changing the ventilation equipment 13 from "0.5 times / h" to "strong operation", the ventilation volume of the living room 50 becomes maximum. As a result, the indoor environment of the living room 50 has its maximum temperature lowered compared to the first condition, and the proportion of carbon dioxide in the air decreases.

[0074] In step S10, as shown in FIG. 7, the CPU 41 reads out the operating conditions corresponding to each of the plurality of symptom information from the memory 42 (step S101). Next, the CPU 41 combines the read plurality of operating conditions (step S102). The CPU 41 combines the operating conditions so that, for example, the operation content of each device 10 included in each of the read plurality of operating conditions becomes one operation content. The CPU 41 records the combined operating conditions in the memory 42. The combination is executed, for example, as follows.

[0075] (When the operation contents included in multiple operation conditions can be executed simultaneously) For example, consider the case where "unable to concentrate" and "runny nose / stuffy nose" are input as multiple symptom information. In the symptom information "unable to concentrate", the operation content for the whole-building air conditioner 11 is changed from the first condition to "-0.5 < PMV < 0". For the symptom information "runny nose / stuffy nose", it is indicated as "-" for the whole-building air conditioner 11. Therefore, the operation content of the whole-building air conditioner 11 can be changed from the first condition to "-0.5 < PMV < 0" corresponding to "unable to concentrate". Note that "unable to concentrate" and "runny nose / stuffy nose" are examples of the first symptom information and the second symptom information respectively. The operation condition corresponding to "unable to concentrate" is an example of the second operation condition. The operation condition corresponding to "runny nose / stuffy nose" is an example of the third operation condition.

[0076] Similarly, for the radiant air conditioner 14, when it is "unable to concentrate", the operation content is changed from the first condition to "ON", but for "runny nose / stuffy nose", it is indicated as "-" and the operation content is not changed. Therefore, the operation content of the radiant air conditioner 14 can be changed from the first condition to "ON" for "unable to concentrate".

[0077] Similarly, for the humidifying / dehumidifying equipment 12, when it is "unable to concentrate", it is indicated as "-" and the operation content is not changed from the first condition, but for "runny nose / stuffy nose", the operation content is changed from the first condition to "dehumidification 40 - 50%". Therefore, the operation content of the humidifying / dehumidifying equipment 12 can be changed from the first condition to "dehumidification 40 - 50%" for "runny nose / stuffy nose".

[0078] Similarly, for the air cleaner 15, when it is "unable to concentrate", it is indicated as "-" and the operation content is not changed from the first condition, but for "runny nose / stuffy nose", the operation content is changed from the first condition to "strong operation". Therefore, the operation content of the air cleaner 15 can be changed from the first condition to "strong operation" for "runny nose / stuffy nose".

[0079] Similarly, for the ventilation equipment 13, when the condition is "unable to concentrate", the operation mode is changed from the first condition to "strong operation", but when the condition is "runny nose or nasal congestion", it is indicated as "-" and the operation content remains unchanged. Therefore, for the condition of "unable to concentrate", the operation content of the ventilation equipment 13 can be changed from the first condition to "strong operation".

[0080] Similarly, for the dimming and color - adjustable lighting 16, when the condition is "unable to concentrate", the operation mode is changed from the first condition to "daylight white 5000K", but when the condition is "runny nose or nasal congestion", it is indicated as "-" and the operation content remains unchanged. Therefore, for the condition of "unable to concentrate", the operation content of the dimming and color - adjustable lighting 16 can be changed from the first condition to "daylight white 5000K".

[0081] As a result, for the two symptom information of "unable to concentrate" and "runny nose or nasal congestion", the CPU 41 determines the operation conditions as follows: the operation content of the whole - building air - conditioning 11 is set to "-0.5 < PMV < 0", the operation content of the radiant air - conditioning 14 is set to "ON", the operation content of the humidity - conditioning equipment 12 is set to "dehumidification 40 - 50%", the operation content of the air cleaner 15 is set to "strong operation", the operation content of the ventilation equipment 13 is set to "strong operation", and the operation content of the dimming and color - adjustable lighting 16 is set to "-".

[0082] (When the operation contents included in multiple operation conditions cannot be executed simultaneously) Also, for example, consider the case where "itchy eyes" and "dry throat" are input as multiple symptom information. The operation content of the air cleaner 15 under the first condition is "OFF". In contrast, the operation content of the air cleaner 15 for "itchy eyes" is "strong operation". On the other hand, the operation content of the air cleaner 15 for "dry throat" is "weak operation". "Strong operation" and "weak operation" cannot be executed simultaneously for the air cleaner 15. In this case, the CPU 41 sets the operation conditions in order from the operation content with a greater environmental change. In this example, as the operation content of the air cleaner 15 under the combined operation conditions, the CPU 41 first sets the operation conditions including the operation content of "strong operation" with a greater environmental change from the operation content of "OFF", which is the operation content of the air cleaner 15 under the first condition. Then, the CPU 41 sets the operation conditions including the operation content of "weak operation" with a smaller environmental change as the next operation conditions.

[0083] In addition, when the operation content of the device 10 is changed arbitrarily by the user (refer to FIG. 11 , step S30), the operation content with a greater environmental change is determined from the changed operation content. For example, when the air cleaner 15 is already operating in "strong operation", as the operation condition with a greater environmental change, " OFF ", and as the operation condition with a smaller environmental change, " Low power operation " is determined.

[0084] Also, for example, consider the case where "very tired" and "heavy head" are input as multiple symptom information. The operation content of the whole-building air conditioner 11 under the first condition is "-0.5 < PMV < 0.5, room-to-room temperature difference ±1°C". In contrast, the operation content of the whole-building air conditioner 11 for "very tired" is "0 < PMV < 0.5". On the other hand, " I have a heavy head.The operation content of the whole-building air conditioner 11 for "" is "-0.5 < PMV < 0". "0 < PMV < 0.5" and "-0.5 < PMV < 0" cannot be executed simultaneously. Also, there is no magnitude in environmental changes. In this case, the CPU 41 determines which operation content to include in the operation conditions for setting first according to whether the change in stimulation becomes larger or smaller with respect to the PMV value in the living room 50 calculated from the detection signal of the sensor 30 and the like.

[0085] For example, when the living room 50 is in an environment where PMV < 0, "0 < PMV < 0.5" becomes the operation condition for transitioning the living room 50 from a cold state to a warm state, and "-0.5 < PMV < 0" becomes the operation for maintaining the living room 50 in a cold state. Therefore, the CPU 41 determines that the operation content of "0 < PMV < 0.5" is the operation content with a large stimulation. Therefore, as the operation content of the whole-building air conditioner 11 in the combined operation conditions, the CPU 41 sets the operation conditions including "0 < PMV < 0.5" as the operation conditions to be set first. And the CPU 41 sets the operation conditions including the operation content of "-0.5 < PMV < 0" with a smaller stimulation as the operation conditions to be set next. Since other operation contents can be executed simultaneously, the CPU 41 sets the operation content of the radiant air conditioner 14 to "ON" and the operation content of the dimming and color-adjusting lighting 16 to "warm white 3500K". Also, the CPU 41 keeps the operation contents of the humidity control equipment 12, the air cleaner 15, and the ventilation equipment 13 under the first condition.

[0086] Also, as another example, as shown in FIG. 8, consider a case where four symptoms, namely "very tired", "heavy head", "itchy eyes", and "dry throat", are input as symptom information. The CPU 41 adopts a state of "-0.5 < PMV < 0" with a greater change from the current state of "PMV = 0.5" for the operation content of the whole-building air conditioning 11. The CPU 41 adopts "ON" which can be executed simultaneously corresponding to the four symptoms for the operation content of the radiant air conditioning 14. The CPU 41 adopts "humidification 50 - 60%" which can be executed simultaneously corresponding to the four symptoms for the operation content of the humidifying equipment 12. The CPU 41 adopts "strong operation" with a greater change for the operation content of the air cleaner 15 from the current "OFF" state. The CPU 41 adopts "strong operation" which can be executed simultaneously corresponding to the four symptoms for the operation content of the ventilation equipment 13. The CPU 41 adopts "warm white 3500K, 2000 lm (lumen)" which can be executed simultaneously corresponding to the four symptoms for the operation content of the dimming and color-tuning lighting 16.

[0087] Next, in step S103, the CPU 41 reads out the operation content of the device 10 that is not a control target in the operation conditions for the plurality of symptoms from the memory 42. When the symptoms are not improved by the operation of the device 10 according to the operation conditions determined by the magnitude of the above environmental change and the magnitude of the stimulus, the CPU 41 determines, as an operation condition (an example of the fourth condition), for operating the device 10 that is not a control target by adding it. The "device 10 that is not a control target" is a device 10 whose settings are not changed in common for the plurality of symptoms, and is the device indicated by "-" in FIG. 3. For example, when two symptom information, namely "very tired" and "unable to concentrate", are input from the user, the "humidifying equipment 12" and the "air cleaner 15" indicated by "-" in FIGS. 3 and 9 correspond to the "device 10 that is not a control target".

[0088] Then, as shown in FIG. 9, the CPU 41 adopts, as the "operating conditions for operating by adding the device 10 that is not the control target", the operating conditions including the following as the operating content: for the whole-building air conditioning 11, "-0.5 < PMV < 0"; for the radiant air conditioning 14, "ON"; for the humidity control device 12, "humidification 50 - 60%"; for the air cleaner 15, "strong operation"; for the ventilation equipment 13, "strong operation"; and for the dimming and color-tuning lighting 16, "white 3500K, 5000 lm (lumens)". In FIG. 9, directly below the name of each device 10, the operating content actually set for each device 10 or the detection value by the sensor 30 is shown with a line under it. Here, for the humidity control device 12, the CPU 41 sets, as the operating content, "humidification 50 - 60%", which has a greater change from the detection value "humidity 40%" currently detected by the sensor 30. Also, for the air cleaner 15, the CPU 41 sets, as the operating content, "strong operation", which has a greater change from the currently set operating content "OFF". The CPU 41 sorts the multiple operating conditions determined as described above and records them in the memory 42 as the operating conditions to be set for the device 10.

[0089] For example, the CPU 41 sorts them in the order of the operating conditions combined in step S102 and the fourth condition, and records them in the memory 42 as the operating conditions to be set for the device 10. For the operating conditions combined in step S102, the CPU 41 further sorts them in the order of the operating conditions with large environmental changes and stimuli and the operating conditions with small environmental changes and stimuli, and records them in the memory 42. Then, the process proceeds to step S15.

[0090] Returning to Figure 6, in step S11, the CPU 41 determines whether more than one hour has passed since the reception date and time of the same and most recent symptom information included in the operation history information. This determination allows the CPU 41 to determine whether sufficient time has passed for the indoor environment to change due to the operating conditions changed as a result of receiving the latest symptom information. The CPU 41 compares the reception date and time of the most recent symptom information obtained from the user terminal 20 with the reception date and time of the same and most recent symptom information. If the obtained reception date and time is more than one hour after the reception date and time of the past symptom information (step S11_YES), the process proceeds to step S12. On the other hand, if less than one hour has passed (step S11_NO), the process proceeds to step S17.

[0091] In step S12, the CPU 41 determines whether the reception time of the most recently acquired symptom information is within two hours of the reception time of the same and latest symptom information included in the operation history information. This determination determines whether the symptom has not improved despite changes in the operating conditions since the previous (latest) symptom information was received. If two hours have not passed, it is determined that the symptom is still present. On the other hand, if two hours have passed, it is determined that this is a new symptom report. If two hours have not passed (step S12_YES), the process proceeds to step S13. On the other hand, if two hours have passed, the process proceeds to step S18.

[0092] In step S13, the CPU 41 determines whether there are any unset operating conditions in relation to the operating conditions already applied. Unset operating conditions are those that have been determined in steps S101 to S103 and recorded in memory 42 but have not yet been set on the device 10 and have not been used in operation. The CPU 41 reads the operating conditions to be set on the device 10 from memory 42. The CPU 41 reads the operation history information from memory 42. The CPU 41 compares the determined operating conditions (see step S10) with the operating conditions included in the operation history information to determine whether there are any unset operating conditions among the determined operating conditions. If there are unset operating conditions (step S13_YES), the process proceeds to step S14. On the other hand, if there are no unset operating conditions (step S13_NO), the process proceeds to step S19.

[0093] For example, consider a case in step S102 where the operating conditions are determined in the following order: operating condition with a large environmental change (changing the air purifier 15 from the first condition "OFF" to "high operation"), operating condition with a small environmental change (changing the air purifier 15 from "OFF" to "low operation"), and the fourth condition. If the device 10 is operating under the first condition, the operating condition with a large environmental change is determined to be an unset operating condition. If the device 10 is already operating under the operating condition with a large environmental change, the operating condition with a small environmental change is determined to be an unset operating condition. If the device 10 is operating under the operating condition with a small environmental change, the fourth condition is determined to be an unset operating condition.

[0094] For example, in step S102, consider the case where the operating conditions are determined in the order of the operating conditions with large environmental changes (changing the first condition from "0.5 times / h" to "strong operation" for the ventilation equipment 13), the operating conditions with small environmental changes (changing from "0.5 times / h" to "weak operation" for the ventilation equipment 13), and the fourth condition. When the device 10 is operating under the first condition, the operating condition with large environmental changes is determined as the unconfigured operating condition. When the device 10 is already operating under the operating condition with large environmental changes, the operating condition with small environmental changes is determined as the unconfigured operating condition. When the device 10 is operating under the operating condition with small environmental changes, the fourth condition is determined as the unconfigured operating condition.

[0095] For example, in step S102, consider the case where the operating conditions are determined in the order of the operating conditions with large environmental changes (changing the first condition from "white 4000K" to "daylight white 5000K" for the dimming and color-tuning lighting 16), the operating conditions with small environmental changes (changing from "white 4000K" to "warm white 3500K" for the dimming and color-tuning lighting 16), and the fourth condition. When the device 10 is operating under the first condition, the operating condition with large environmental changes is determined as the unconfigured operating condition. When the device 10 is already operating under the operating condition with large environmental changes, the operating condition with small environmental changes is determined as the unconfigured operating condition. When the device 10 is operating under the operating condition with small environmental changes, the fourth condition is determined as the unconfigured operating condition.

[0096] For example, in step S102, consider the case where the operating conditions are determined in the order of the operating conditions with large stimuli (changing to "0 < PMV < 0.5" for the central air-conditioning 11), the operating conditions with small stimuli (changing to "-0.5 < PMV < 0" for the central air-conditioning 11), and the fourth condition. When the device 10 is operating under the first condition, the operating condition with large stimuli is determined as the unconfigured operating condition. When the device 10 is already operating under the operating condition with large stimuli, the operating condition with small stimuli is determined as the unconfigured operating condition. When the device 10 is operating under the operating condition with small stimuli, the fourth condition is determined as the unconfigured operating condition.

[0097] For example, in step S102, as an example, when the indoor humidity is 45% (less than 50%), consider the case where the operating conditions are determined in the order of operating conditions with a large stimulus (changing the humidification of the humidifying and dehumidifying device 12 to 50 - 60%), operating conditions with a small stimulus (changing the dehumidification of the humidifying and dehumidifying device 12 to 40 - 50%), and the fourth condition. When the device 10 is operating under the first condition, the operating condition with a large stimulus is determined as an unconfigured operating condition. When the device 10 is already operating under the operating condition with a large stimulus, the operating condition with a small stimulus is determined as an unconfigured operating condition. When the device 10 is operating under the operating condition with a small stimulus, the fourth condition is determined as an unconfigured operating condition.

[0098] Also, for example, as shown in FIG. 8, when symptoms such as "very tired", "heavy head", "itchy eyes", and "dry throat" are input and the operating conditions are changed, the entire building air conditioner 11 "0 < PMV < 0.5" and the air purifier 15 "weak operation" are determined as unconfigured operating conditions.

[0099] In step S14, the CPU 41 sets the next operating condition to be set among the determined operating conditions for the device 10. For example, the CPU 41 sets either the unconfigured combination detected in step S13, the operating condition for which the flag indicating improvement set in step S19 is set, the operating condition for a single symptom set in step S9, or the operating condition set in step S10 for the device 10.

[0100] Next, the CPU 41 operates the device 10 under the set operating condition (an example of the second operation process, the third operation process, and the fourth operation process, step S15). Next, the CPU 41 adds the information for identifying the user, the symptoms, the set operating condition, and the reception date and time when the symptom information was obtained to the operation result information and records it in the memory 42 (step S16). That is, the operation condition used for the operation according to the symptom information is added to the operation result information, and the operation result information including the added operation condition is recorded in the memory 42.

[0101] For example, if the "operating conditions with significant environmental changes" set in step S104 is the operating condition set for device 10 instead of the first condition, the user identifier, the symptoms "itchy eyes" and "dry throat," the set operating conditions (radiant air conditioning 14 "ON", humidity control device 12 "humidification 50-60%", air purifier 15 "high operation", dimmable and color-adjustable lighting 16 "2000lm (lumens)"), and the specific date and time the symptom information was received are added as operational performance information.

[0102] In step S17, the CPU 41 causes the user terminal 20 to display an indication that less than one hour has elapsed since the last input. This allows the operating conditions to be maintained without change for a period of time after the change until the effect of the change becomes apparent. The process then returns to step S5.

[0103] In step S18, the CPU 41 determines whether there are any operating conditions in the operational history information that are flagged as having been improved for the same user with the same symptoms. If there are operating conditions that are flagged as having been improved (step S18_YES), the process proceeds to step S19. On the other hand, if there are no operating conditions that are flagged as having been improved (step S18_NO), the process proceeds to step S20.

[0104] In step S19, the CPU 41 sets the operating conditions included in the operational performance information that have been flagged to indicate improvement in symptoms (an example of an improved operating condition) as the operating conditions for device 10. The process then proceeds to step S15. The operation of marking conditions to indicate improvement in symptoms will be described later.

[0105] In step S20, the CPU 41 reads advice information, which is advice to improve the symptoms, from memory 42 and outputs it to the user terminal 20 (an example of advice output processing). The advice is a message that encourages lifestyle improvements, such as, as shown in Figure 10, "Are you feeling stressed at work? We recommend that you get more than X hours of sleep." After outputting the advice information to the user terminal 20, the CPU 41 returns the operating conditions of the device 10 to the first condition. This completes the processing in this flow.

[0106] Next, as shown in Figure 11, the CPU 41 determines whether or not it has received a signal from the user terminal 20 indicating a change in the settings of the device 10 (step S21). "Change in the settings of the device 10" refers to any change in the settings of the indoor environment made by the user, and means a change in at least one of the following: turning the device 10 on or off, temperature, humidity, airflow, lighting color, and lighting brightness. The instruction to change the settings is, for example, input from the user to the user terminal 20. The input instruction to change the settings is transmitted from the user terminal 20 to the control device 40. If the CPU 41 has not received a signal indicating an instruction to change the settings from the user terminal 20 (step S21_YES), the process proceeds to step S22. On the other hand, if the CPU 41 has received a signal from the user terminal 20 (step S21_NO), the process proceeds to step S30.

[0107] In step S22, the CPU 41 determines whether two hours have elapsed since the input of symptom information. If two hours have elapsed, the process proceeds to step 22. On the other hand, if two hours have not elapsed, the process proceeds to step S31. The processing in step S22 when the operation of device 10 is combined for symptom input from multiple users will be described later.

[0108] In step S23, the CPU 41 terminates the modification of the operating conditions corresponding to the symptoms included in the symptom information, provided that two hours have elapsed without acquiring symptom information. In other words, it indicates that the symptoms indicated by the symptom information have been alleviated by the operation of the device 10 whose operating conditions have been modified, and that there is no need to further modify and maintain the operating conditions. The CPU 41 flags the most recent operating conditions included in the operation performance information recorded in step S16 as operating conditions that have improved the symptoms (an example of improved operating conditions) and records them in memory 42. If multiple users have entered symptoms (see step S31), the CPU 41 flags the combined operating conditions as operating conditions that have improved the symptoms of the first user and the second user, as described later, and records them in memory 42.

[0109] Next, CPU 41 refers to the operational performance information to count the frequency of the improved symptoms. CPU 41 determines whether the frequency of occurrence exceeds a predetermined level, for example, whether symptom information was obtained at least four days a week or at least once a week in a month (step S24). If symptom information was obtained (step S24_YES), the process proceeds to step S25. On the other hand, if no symptom information was obtained (step S24_NO), the process according to this flow ends.

[0110] In step S25, the CPU 41 flags the operating conditions that indicate the relevant symptoms included in the operation history information as frequently occurring operating conditions. For example, the CPU 41 flags the most recently improved operating condition as an operating condition corresponding to a frequently occurring symptom. Next, the CPU 41 determines whether there are other frequently occurring operating conditions (step S26). That is, the CPU 41 determines whether there are any operating conditions that indicate improvement for other symptoms of the same user and that correspond to symptoms different from the most recent symptom, among the operating conditions that have been determined to be frequently occurring. If there are other frequently occurring operating conditions (step S26_YES), the process proceeds to step S27. On the other hand, if there are no other frequently occurring operating conditions (step S26_NO), the process proceeds to step S28.

[0111] In step S27, the CPU 41 determines whether the other frequently occurring operating conditions and the most recent frequently occurring operating condition for which a flag has newly been set can be executed simultaneously. If they can be executed simultaneously (step S27_YES), the process proceeds to step S28. On the other hand, if they cannot be executed simultaneously (step S27_NO), the process proceeds to step S36.

[0112] For example, consider a case where the operating content “0 < PMV < 0.5” for “very tired” with respect to the whole-building air conditioner 11 is included in the most recent frequently occurring operating condition for which a flag has newly been set. As another frequently occurring operating condition, if the operating content “−0.5 < PMV < 0” for “heavy head” with respect to the whole-building air conditioner 11 is included, since the PMV ranges are different from each other, they cannot be executed simultaneously.

[0113] In step S28, the CPU 41 updates the most recent frequently occurring operating condition (an example of an improved operating condition) for which a flag has newly been set as the first condition. That is, the CPU 41 sets, as the operating condition when starting the device 10, the most recent operating condition (an example of an improved operating condition) improved for the frequently occurring symptom. Thereby, for example, when the operating content “0 < PMV < 0.5” for “very tired” with respect to the whole-building air conditioner 11 is included in the most recent frequently occurring operating condition, the whole-building air conditioner 11 is started with the operating content “0 < PMV < 0.5” instead of the first condition “−0.5 < PMV < 0.5” when starting the whole-building air conditioner 11. Further, the CPU 41 sets a flag indicating that the first condition has been updated and records it in the memory 42. Then, the process proceeds to step S29.

[0114] Note that the CPU 41 may set a flag indicating that it is to be set as the first condition for the most recent frequently occurring operating condition included in the operation result information and record it in the memory 42. In this case, when starting the device 10, the CPU 41 reads out the first condition and also reads out the operation result information from the memory 42. The CPU 41 may set, as the operating condition of the device 10, the operating condition for which the flag to be set as the first condition is set, instead of the first condition, among the operation result information read out.

[0115] In step S29, the CPU 41 returns the operation of device 10 to the operation under the first condition. That is, assuming that the user's symptoms have improved, the operation of device 10 is returned from the operating conditions for addressing the symptoms to the operating conditions for starting device 10. With this, the processing in this flow ends.

[0116] In step S30, the CPU 41 sets the operating conditions changed by the user to the device 10 and operates the device 10. The CPU 41 also updates the operating conditions that are currently in operation, which are determined in response to the symptom information, to the operating conditions instructed by the user. The updated operating conditions are recorded in memory 42. For example, the CPU 41 updates the latest operating conditions recorded in the operation history information to the changed operating conditions and records them in memory 42. The process then proceeds to step S22.

[0117] In step S31, the CPU 41 determines whether or not a symptom has been entered by another user via the user terminal 20. Here, "another user" refers to a user different from the user who previously entered the symptom, who is staying in the same building 100 (living room 50) as the user who previously entered the symptom, and who is logged into the indoor environment adjustment system 1. If a symptom has been entered by another user (step S31_YES), the process proceeds to step S32. On the other hand, if no symptom has been entered by another user (step S31_NO), the process proceeds to step S33. The CPU 41 processes users who have entered a symptom within a predetermined time (e.g., 2 hours) starting from the time the user who previously entered the symptom entered the symptom, as "other users". On the other hand, the CPU 41 does not treat users who entered a symptom more than 2 hours after the starting point as "other users", but instead treats them as new users and proceeds with the processing in step S5 (see step S22_YES).

[0118] In step S32, the CPU 41 determines the priority between the user who has already entered symptoms (hereinafter referred to as the first user) and other users (hereinafter referred to as the second user). In step S32, as shown in Figure 12, the CPU 41 reads the user information of the first user and the number of symptoms entered by the first user from the memory 42 (step S301).

[0119] Next, the CPU 41 reads the user information of the second user and the number of symptoms entered by the second user from the memory 42 (step S302). Next, the CPU 41 reads the weighting coefficients from the memory 42 (step S303).

[0120] Next, the CPU 41 calculates an index indicating the priority level of each user (step S304, an example of calculation process). Specifically, the CPU 41 calculates the index based on the read weighting coefficients, read user information, and read symptom counts. For example, the CPU 41 calculates the index as the product of the weighting result corresponding to the user information and the symptom count for each user.

[0121] For example, if the first user is a "minor" and reports one symptom, CPU41 calculates an index of 1 (number of symptoms) × 1.4 (weighting coefficient for "minor") = 1.4. If the second user is a "female" and reports one symptom, CPU41 calculates an index of 1 (number of symptoms) × 1.2 (weighting coefficient for "female") (hereinafter referred to as the first example).

[0122] Furthermore, for example, if the first user is a "female" who reports one symptom, CPU41 calculates an index of 1 (number of symptoms) × 1.2 (weighting coefficient for "female") = 1.2. If the second user is a "hypersensitive" user who reports one symptom, CPU41 calculates an index of 1 (number of symptoms) × 1.5 (weighting coefficient for "hypersensitive") = 1.5 (hereinafter referred to as the second example).

[0123] Next, in step S305, the CPU 41 compares the index of the first user with the index of the second user. If the index of the first user is greater than or equal to the index of the second user (step S305_YES, the first example), the process proceeds to step S306. On the other hand, if the index of the second user is greater than the index of the first user (step S305_NO, the second example), the process proceeds to step S307.

[0124] In step S306, the CPU 41 executes a process that prioritizes the first user (an example of a determination process). Specifically, the CPU 41 records, in the memory 42, information for identifying the first user as the prioritized user. The CPU 41 determines an operating condition that combines the operating conditions corresponding to the symptoms reported by the second user while prioritizing the operating conditions corresponding to the symptoms reported by the first user.

[0125] For example, in the above first example, assume that the symptom "very tired" (an example of the third symptom information) is input from the first user to the user terminal 20. The CPU 41 operates the devices with the operating conditions of the whole-building air conditioner 11 "0 < PMV < 0.5", the radiant air conditioner 14 "ON", the humidifying / dehumidifying device 12 "no operation", the air cleaner 15 "no operation", the ventilation equipment 13 "no operation", and the dimming / color-tuning lighting 16 "warm white 3500K" as the operating conditions of the device 10 (an example of the fifth condition, see FIG. 3).

[0126] Thereafter, assume that within two hours from the input of the symptom "very tired" by the first user, the symptom "throat is dry" (an example of the fourth symptom information) is input from the second user. Based on the symptom of the second user, the CPU 41 determines the operation of the device 10 for the second user as the whole-building air conditioner 11 "no operation", the radiant air conditioner 14 "ON", the humidifying / dehumidifying device 12 "humidification 50 - 60%", the air cleaner 15 "weak operation", and the ventilation equipment 13 and the dimming / color-tuning lighting 16 "no operation" (an example of the sixth condition, see FIG. 3).

[0127] The CPU 41 combines the operating conditions by adding the operating content for a device that can add the operating conditions according to the symptoms of the second user to the operating conditions according to the symptoms of the first user. As shown in FIG. 13, for the operating conditions for the symptoms of the first user, in the operating conditions for the symptoms of the second user, the operating contents of the radiant air conditioner 14 "ON", the humidifying equipment 12 "humidification 50 - 60%", and the air cleaner 15 "weak operation" are not set in the operating conditions for the symptoms of the first user, so they can be added to the operating conditions for the symptoms of the first user. Therefore, in the first example, as a result of combining the operating conditions of the first user and the operating conditions of the second user, the CPU 41 operates the devices with the operating contents of the whole-building air conditioner 11 "0 < PMV < 0.5", the radiant air conditioner 14 "ON", the humidifying equipment 12 "humidification 50 - 60%", the air cleaner 15 "weak operation", the ventilation equipment 13 "no operation", and the dimming and color-adjusting lighting 16 "warm white 3500K" (an example of the fifth operation process). Thereby, the process of FIG. 12 ends. The process proceeds to step S15 of FIG. 6.

[0128] In step S307, the CPU 41 executes a process that prioritizes the second user (an example of a determination process). Specifically, the CPU 41 records, in the memory 42, information for identifying the second user as the prioritized user. The CPU 41 determines the operating conditions by combining the operating conditions corresponding to the symptoms reported by the first user while prioritizing the operating conditions corresponding to the symptoms reported by the second user.

[0129] For example, in the above second example, assume that the user terminal 20 has input the symptom "very tired" (an example of the third symptom information) from the first user. The CPU 41 operates the devices with the operating contents of the whole-building air conditioner 11 "0 < PMV < 0.5", the radiant air conditioner 14 "ON", the humidifying equipment 12 "no operation", the air cleaner 15 "no operation", the ventilation equipment 13 "no operation", and the dimming and color-adjusting lighting 16 "warm white 3500K" as the operating conditions of the device 10 (an example of the fifth condition, see FIG. 3).

[0130] Subsequently, it is assumed that within two hours from the input of the symptom "very tired" by the first user, the second user inputs the symptom "heavy head" (an example of the fourth symptom information). Based on the symptom of the second user, the CPU 41 determines the operations of the device 10 for the second user as follows: the whole-building air conditioner 11 "-0.5 < PMV < 0", the radiant air conditioner 14 "ON", the humidity control device 12 and the air purifier 15 "not operating", the ventilation equipment 13 "weak operation", and the dimming and color-adjustable lighting 16 "not operating" (an example of the sixth condition, see Figure 3).

[0131] For devices that can add the operating conditions corresponding to the symptoms of the first user to the operating conditions corresponding to the symptoms of the second user, the CPU 41 combines the operating conditions by adding the operating conditions. As shown in Figure 14, for the operating conditions for the symptoms of the second user, the operation of the dimming and color-adjustable lighting 16 "warm white 3500K" in the conditions of the first user is not set in the operating conditions of the first user, so it can be added to the operating conditions for the symptoms of the second user. On the other hand, in the conditions of the first user, the whole-building air conditioner 11 "0 < PMV < 0.5" conflicts with the whole-building air conditioner 11 "-0.5 < PMV < 0" in the conditions of the second user, so the operating conditions of the second user take precedence. Therefore, the CPU 41 operates the device under the operating conditions of the whole-building air conditioner 11 "-0.5 < PMV < 0", the radiant air conditioner 14 "ON", the humidity control device 12 and the air purifier 15 "not operating", the ventilation equipment 13 "strong operation", and the dimming and color-adjustable lighting 16 "warm white 3500K" (an example of the fifth operation process). Thereby, the process in Figure 12 ends. The process proceeds to step S15 in Figure 6.

[0132] Returning to Figure 11, in step S33, the CPU 41 determines whether or not there is input of symptom information related to the same symptom from the user terminal 20. Specifically, when the CPU 41 receives symptom information from the user terminal 20 with new symptom input, it reads the operation history information from memory 42. The CPU 41 refers to the latest operation conditions included in the operation history information and determines whether the symptom information is from the same user and indicates the same symptom. If there is input of the same symptom from the same user (step S33_YES), the process proceeds to step S34. On the other hand, if there is no input of the same symptom from the same user (step S31_NO), the process returns to step S22.

[0133] This means that, for example, if symptom information regarding the same symptom is entered by the same user, it is determined whether or not the symptom has improved based on the operating conditions under which device 10 is currently running. If no symptom information regarding the same symptom is entered, the process waits for 2 hours to determine whether or not the symptom has improved.

[0134] In step S34, the CPU 41 determines that the same symptoms are still persisting and sets the operating conditions currently running the device 10, as "unimproved," in the operation history information, because no improvement in symptoms was obtained. That is, the CPU 41 sets the variable for the relevant operating conditions in the operation history information to "0" or "×" and records it in memory 42. The process then returns to step S6.

[0135] In step S35, the CPU 41 compares the number of occurrences of other frequently occurring operating conditions with the number of occurrences of the newly flagged frequently occurring operating conditions. If the number of occurrences of the newly flagged frequently occurring operating conditions is higher (step S33_YES), the process proceeds to step S27. On the other hand, if the number of occurrences of other frequently occurring conditions is higher (step S33_NO), the process proceeds to step S28.

[0136] Next, the process of returning the operating conditions set as the first condition in step S24 back to the original operating conditions will be explained with reference to Figure 15. The process in Figure 15 is, for example, a process that is performed at regular intervals.

[0137] First, CPU41 refers to the operational history information to determine whether there are any operational conditions that have been flagged as frequently occurring symptoms (step S201). If there are frequently occurring symptoms (step S201_YES), the process proceeds to step S202. On the other hand, if there are no frequently occurring symptoms (step S201_NO), the process in this flow terminates.

[0138] In step S202, CPU 41 determines whether the operating conditions flagged as frequently occurring symptoms in the operation history information have been entered as symptom information within the last month. That is, it determines whether any operating conditions with the same symptom information as the operating conditions flagged as frequently occurring symptoms in the operation history information are included in the reception date and time within the last month. If the symptom information has been entered within the last month (step S202_YES), the processing in this flow ends. On the other hand, if no symptoms have been entered within the last month (step S202_NO), the process proceeds to step S203.

[0139] In step S203, the CPU 41 removes the flag indicating frequent occurrence from operating conditions included in the operation history information that have not had symptom information entered within the last month and are flagged as frequent occurrences. That is, the CPU 41 updates the variable indicating frequent occurrence to "0" or "×" for operating conditions that are flagged as frequent occurrences. The CPU 41 records the operation history information, including the updated operating conditions, in memory 42. Next, the CPU 41 determines whether the operating conditions flagged as frequent occurrences were set as the first condition (step S204). The CPU 41 uses the flag indicating whether the first condition has been updated and the content of the updated first condition to determine whether the operating conditions flagged as frequent occurrences are set as the first condition. If it is set as the first condition (step S204_YES), the process proceeds to step S205. On the other hand, if it is not set as the first condition (step S204_NO), that is, if the operating conditions of other frequently occurring symptom information are set as the first condition, the process in this flow terminates.

[0140] In step S205, the CPU 41 determines whether there are any operating conditions marked as frequently occurring symptoms, in addition to the operating conditions from which the flag has been removed. That is, it determines whether there are any operating conditions that are not set as the first condition but are flagged as frequently occurring symptom information, within the reception date and time within the last month. If there are frequently occurring symptoms (step S205_YES), the process proceeds to step S206. On the other hand, if there are no frequently occurring symptoms (step S205_NO), the process proceeds to step S207.

[0141] In step S206, the CPU 41 changes the first condition to another frequently occurring operating condition. The CPU 41 records the updated first condition in memory 42. The CPU 41 also sets a flag on the other frequently occurring operating condition to indicate that the first condition has been updated. The CPU 41 records the operation history information, including the flagged operating condition, in memory 42. As a result, operating conditions that were flagged as frequently occurring but were not set as the first condition are updated to be the first condition. Furthermore, if, for example, several operating conditions related to different symptoms are flagged as operating conditions for frequently occurring symptoms, the CPU 41 updates the operating condition for the symptom with the highest frequency of occurrence as the first condition, and then records the first condition and the operation history information in memory 42. This completes the processing in this flow.

[0142] In step S207, the CPU 41 restores the first condition from the operating condition with the flag removed to the original first condition and records it in memory 42. The CPU 41 also erases the flag indicating that the first condition has been updated and records it in memory 42. This completes the processing in this flow.

[0143] (Explanation of when improvement is judged) Next, we will explain the timing at which improvement is determined when operating conditions are combined according to the symptoms of multiple users. The timing at which improvement is determined is determined, for example, by step S22 described above.

[0144] (In the case of the first example) As shown in Figure 16, the first user logs in via the user terminal 20 (step S401). After logging in, the first user inputs a symptom via the user terminal 20 (step S402). The CPU 41 changes the operating conditions of the device based on the input symptom (step S403).

[0145] Next, the second user logs in via user terminal 20 (step S404). After logging in, the second user enters the symptoms via user terminal 20 (step S405).

[0146] The CPU 41 determines the operating conditions for the device 10 according to step S32 in Figure 11 (step S406). If the CPU 41 does not receive further symptom input from the first user within two hours after the first user inputs a symptom (step S402), it records information indicating improvement for the first user in memory 42 (step S407). Similarly, if the CPU 41 does not receive further symptom input from the second user within two hours after the second user inputs a symptom (step S405), it records information indicating improvement for the second user in memory 42 (step S408). As described above, if the operating conditions determined for the first user's symptoms have not been changed by the symptoms input by the second user (i.e., the first user takes priority), the CPU 41 records information indicating improvement in memory 42 when two hours have passed since each user inputted their symptoms and there have been no further symptom inputs. If the same symptoms are input from either the first or second user before the two hours have elapsed, the timing for determining improvement is determined as follows.

[0147] (If the first user has entered the same symptoms) As shown in Figure 17, after determining the operating conditions of the device 10 taking into account the symptoms of the second user (step S406), consider the case where the first user inputs the same symptoms again within two hours of the first user inputting their symptoms (step S402) (step S507). The CPU 41 records information indicating that the first user's symptoms have not improved in the memory 42 (step S508).

[0148] Next, the CPU 41 reads operating conditions from memory 42 in the following order, based on the operating conditions of the first user currently in use. The CPU 41 also determines the operating conditions by combining the read operating conditions with the operating conditions of the second user (step S509). Two hours have passed since the first user entered the same symptoms, and the CPU 41 records information in memory 42 indicating the improvement of the symptoms for both the first and second users (step S510).

[0149] If the first user enters the same symptoms again before two hours have elapsed since the first user entered the same symptoms, steps S507 and below are repeated. If the second user enters the same symptoms before two hours have elapsed since the first user entered the same symptoms, steps S607 and below in Figure 18 are repeated.

[0150] (If a second user enters the same symptoms) As shown in Figure 18, after determining the operating conditions of the device 10 taking into account the symptoms of the second user (step S406), we consider the case where the second user inputs the same symptoms within two hours of the second user inputting the symptoms (step S405) (step S607). The CPU 41 records information indicating that the second user's symptoms have not improved in the memory 42 (step S608).

[0151] Next, the CPU 41 reads operating conditions from memory 42 in the following order, based on the operating conditions of the second user that are currently being used. The CPU 41 also determines the operating conditions by combining the read operating conditions with the operating conditions of the first user (step S609). When two hours have elapsed since the first user entered the symptoms, the CPU 41 records information in memory 42 indicating the improvement of the first user's symptoms (step S610). When two hours have elapsed since the second user entered the same symptoms, the CPU 41 records information in memory 42 indicating the improvement of the second user's symptoms (step S611).

[0152] If the first user enters the same symptoms again before two hours have elapsed since the first user entered the same symptoms, steps S507 and below in Figure 17 are repeated. If the second user enters the same symptoms before two hours have elapsed since the first user entered the same symptoms, steps S607 and below are repeated.

[0153] (In the case of the second example) As shown in Figure 19, the first user logs in via the user terminal 20 (step S501). After logging in, the first user inputs a symptom via the user terminal 20 (step S502). The CPU 41 changes the operating conditions of the device 10 based on the input symptom (step S503).

[0154] Next, the second user logs in via user terminal 20 (step S504). After logging in, the second user enters the symptoms via user terminal 20 (step S505).

[0155] The CPU 41 determines the operating conditions for the device 10 according to step S32 in Figure 11 (step S506). If there is no further input of symptoms from the first user or the second user within two hours after the input of symptoms from the second user (step S505), the CPU 41 records information indicating improvement for the first user and the second user in memory 42 (step S507). As described above, if the operating conditions corresponding to the symptoms of the first user are changed based on the operating conditions determined for the symptoms of the second user (i.e., the second user takes priority), the CPU 41 records information indicating improvement in memory 42 when two hours have passed since the input of symptoms from the second user without further input of symptoms. If the same symptoms are input from either the first user or the second user before the two hours have elapsed, the process is as follows.

[0156] (If the first user has entered the same symptoms) As shown in Figure 20, after determining the operating conditions of the device 10 taking into account the symptoms of the second user (step S504), consider the case where the first user inputs the same symptoms again within two hours of the first user inputting their symptoms (step S502) (step S707). The CPU 41 records information indicating that the first user's symptoms have not improved in the memory 42 (step S708).

[0157] Next, the CPU 41 reads operating conditions from memory 42 in the following order, based on the operating conditions of the first user currently in use. The CPU 41 also determines the operating conditions by combining the read operating conditions with the operating conditions of the second user (step S709). When two hours have elapsed since the second user entered the symptoms, the CPU 41 records information indicating the improvement of the second user's symptoms in memory 42 (step S710). When two hours have elapsed since the first user entered the symptoms, the CPU 41 records information indicating the improvement of the second user's symptoms in memory 42 (step S711).

[0158] If the first user enters the same symptoms again before two hours have elapsed since the first user entered the same symptoms, steps S707 and below are repeated. If the second user enters the same symptoms before two hours have elapsed since the first user entered the same symptoms, steps S807 and below in Figure 21 are repeated.

[0159] (If a second user enters the same symptoms) As shown in Figure 21, after determining the operating conditions of the device 10 taking into account the symptoms of the second user (step S506), we consider the case where the second user inputs the same symptoms within two hours of the second user inputting the symptoms (step S505) (step S807). The CPU 41 records information indicating that the second user's symptoms have not improved in the memory 42 (step S808).

[0160] Next, the CPU 41 reads operating conditions from memory 42 in the following order, based on the operating conditions of the second user that are currently being used. The CPU 41 also determines the operating conditions by combining the read operating conditions with the operating conditions of the first user (step S809). Two hours have passed since the second user entered the same symptoms, and the CPU 41 records information in memory 42 indicating the improvement of the symptoms of both the first and second users (step S810).

[0161] If the first user enters the same symptoms again before two hours have elapsed since the first user entered the same symptoms, steps S707 and below in Figure 20 are repeated. If the second user enters the same symptoms before two hours have elapsed since the first user entered the same symptoms, steps S807 and below are repeated.

[0162] (Effects and effects according to the embodiment) The user can input multiple symptoms they are experiencing into the user terminal 20. The CPU 41 controls the indoor environment by operating multiple devices 10 according to the operating conditions corresponding to the symptom information indicated by the input symptoms. If the user has input two or more symptoms, and there is a device 10 that cannot simultaneously execute the operating conditions corresponding to each symptom, the CU 41 operates the device 10 according to the operating condition that causes the greatest change in the indoor environment from among the multiple operating conditions. This creates an indoor environment in which the user's multiple symptoms are alleviated.

[0163] By using the sensor 30, the indoor environment can be accurately detected. Furthermore, for equipment 10 with defined operating conditions within a range, it is possible to determine which of multiple operating conditions causes the greatest change in the indoor environment.

[0164] If, among two operating conditions that cannot be executed simultaneously, the symptoms related to the two received symptom information do not improve under one of the operating conditions selected based on the relative strength of the environmental changes or the magnitude of the stimuli, the device 10 is operated under the other operating condition that was not selected, thereby creating an indoor environment that alleviates multiple symptoms of the user.

[0165] If operating device 10 under two operating conditions that cannot be executed simultaneously does not improve the user's multiple symptoms, the CPU 41 will create an indoor environment that alleviates the user's multiple symptoms by changing the operating conditions of device 10 from the first condition to a fourth condition.

[0166] When an indoor environment that improves multiple symptoms cannot be achieved under any of the operating conditions, the system can provide advice on user actions.

[0167] By operating device 10 based on past operating conditions that have been flagged to indicate an improvement in the user's symptoms, an indoor environment is created in which multiple symptoms of the user are reliably alleviated.

[0168] When multiple devices 10 are operated under the first condition, if the user frequently experiences multiple symptoms, the first condition for starting the multiple devices 10 is updated to a past operating condition where a flag indicating that the user's symptoms have improved is set. This reduces the likelihood of the user experiencing symptoms after the multiple devices 10 have been started.

[0169] The system can operate by combining operating conditions based on symptoms entered by two users. This allows for simultaneous improvement of symptoms for both users.

[0170] (modified version) In the above embodiment, one or two symptoms were described as examples of input symptoms, but the system is not limited to these. Three or more symptoms may be input. If two or more symptoms are input, the user may select which symptoms to prioritize for improvement. The indoor environment adjustment system 1 may prioritize the improvement of the symptoms that were selected for priority improvement, and then perform improvement of the remaining symptoms. Furthermore, if three or more symptoms are input, up to two symptoms that can be improved may be selected.

[0171] Furthermore, in the above embodiment, a whole-house air conditioning system 11 that controls the temperature, humidity, and airflow of both the living rooms 50 and the corridors 51 was described as an example of the equipment 10, but it is not limited to this. It may be air conditioning equipment, humidity control equipment 12, and ventilation equipment installed in each room that control the temperature, humidity, and airflow of only the living rooms 50 or the corridors 51.

[0172] Furthermore, although an example using sensor 30 was described in the above embodiment, the invention is not limited to this. Even if sensor 30 is not present, the device 10 may be operated by setting an operating condition that does not use the value of sensor 30 as the first condition. This makes it possible to determine the indoor environment by operating the device 10 based on the first condition, even if there is no sensor 30 in the room.

[0173] Furthermore, in the above embodiment, if multiple users input multiple symptoms, the operating conditions for each user may be determined by the flow from step S101 to step S108 (see Figure 8).

[0174] Furthermore, although the above embodiment described two hours as an example of a predetermined time or a time for determining improvement, it is not limited to this. Any time that allows for the determination that improvement has been achieved by changing the operating conditions may be longer or shorter than two hours.

[0175] Furthermore, although the above embodiment described a case where symptoms are entered by two users, the number is not limited to two, and may be three or more. If there are three or more users, priority may be assigned to each of the three or more users. The CPU 41 may combine operating conditions corresponding to each of the three or more users. If the combination of operating conditions results in a change in the operating conditions corresponding to the user's symptoms, the CPU 41 may determine that the symptoms have improved if the user does not input the same symptoms within two hours from the time of the change. If the combination of operating conditions does not result in a change in the operating conditions corresponding to the user's symptoms, the CPU 41 may determine that the symptoms have improved if the user does not input the same symptoms within two hours from the time the user input the symptoms.

[0176] Also, in the above embodiment, when the CPU 41 does not improve under the operating conditions shown in FIG. 3, it may further determine other operating conditions. For example, when the symptom "very tired" is input again, the CPU 41 may change the whole-building air conditioning 11 from "0 < PMV < 0.5" to "0.5 < PMV < 1.0". Also, when the symptom is improved by other operating conditions, the CPU 11 may start the device 10 under other operating conditions instead of the first condition.

[0177] Also, in the above embodiment, when the CPU 41 does not improve under the operating conditions shown in FIG. 3 and the operating conditions of the air cleaner 15 are included in the operating conditions (for example, symptoms such as "unable to concentrate", "runny nose or stuffy nose"), it may determine an operating condition to turn the operating content of the air cleaner 15 to "OFF". When the symptom is improved by turning the air cleaner 15 to "OFF", the CPU 41 may modify the operating content of the air cleaner 15 for the symptom information shown in FIG. 3 to be "OFF". Thereby, for example, when it is considered that the adverse effect of the air flow is greater than the removal ability of the air cleaner 15, it can be changed in advance so that the air cleaner 15 does not operate.
