[Light emission control of the light emitter 24 by the light emission control device 25 in Embodiment 1]
Next, the flow of light emission control of the light emitter 24 by the light emission control device 25 will be explained. FIG. 6 is a flowchart showing the flow of light emission control by the light emission control device 25 of the first embodiment. The light emission control shown in FIG. 6 is executed by the CPU 101 in the light emission control device 25 while the air conditioning system 1 is operating.

In step S1, the light emission control device 25 acquires data indicating whether or not it is time to start operation of the air conditioning system 1 from the system control device 11, and determines whether the current time is the time to start operation of the air conditioning system 1. to judge.

If it is determined in step S1 that it is time to start operation, the light emitting body 24 of the air outlet 2 starts emitting light in the first color shown in FIG. 4 in step S2. Thereby, the user can recognize that it is time to start operation based on the color of the light emitted from the light emitter 24 of the air outlet 2.

On the other hand, if it is determined in step S1 that it is not the time to start operation, the light emission control device 25 acquires data indicating the current operation mode of the air conditioning system 1 from the system control device 11 in step S3. In step S4, the light emission control device 25 acquires current air volume control data in the air conditioning system 1 from the system control device 11. In step S5, the light emission control device 25 acquires air quality detection data by the air quality sensor 14 from the system control device 11.

In step S6, it is determined whether the air quality detection value is an abnormal value based on the air quality detection data acquired in step S5. Specifically, in step S6, for example, when the concentration of carbon dioxide detected by the vacancy sensor exceeds a predetermined threshold value, it is determined that the detected value of air quality is an abnormal value.

If it is determined in step S6 that the air quality detection value is not an abnormal value, in step S7, the emitted light color of the light emitter 24 at the air outlet 2 is changed to one of the second to fourth colors shown in FIG. The color is controlled to correspond to the current driving mode. Specifically, in step S7, the data table showing the relationship shown in FIG. 4 stored in the ROM is referred to, a luminescent color corresponding to the driving mode indicated by the data acquired in step S3 is selected, and the luminescent color is emitted in the selected luminescent color. The body 24 is made to emit light.

On the other hand, if it is determined in step S6 that the air quality detection value is an abnormal value, in step S8, the color of the light emitted from the light emitter 24 at the air outlet 2 is controlled to the fifth color shown in FIG. 4. Specifically, in step S8, the data table stored in the ROM is referred to, the fifth color corresponding to the warning state is selected, and the light emitter 24 is caused to emit light in the selected fifth color.

After step S7 and after step S8, proceed to step S9. In step S9, the amount of light emitted by the light emitting body 24 at the air outlet 2 is controlled to a color corresponding to the current air volume setting level among the amounts of light emitted from the light emitting amount shown in FIG. 5, and the process ends. Specifically, in step S9, the data table showing the relationship shown in FIG. The light emitter 24 is caused to emit light.

By repeatedly executing steps S1 to S9, the light emission control device 25 causes the light emitting body 24 of the air outlet 2 to emit light in the first color at the start of the operation of the air conditioning system 1, and then The light emitting body 24 of the air outlet 2 is caused to emit light in the second to fourth colors corresponding to the color. Thereby, the color of the light emitted from the light emitting body 24 at the air outlet 2 indicates which of the current operating state is at the start of operation, the cooling mode, the heating mode, and the ventilation mode. Thereby, the user can easily check the operating status including the operating status of the air conditioning system 1 by visually recognizing the luminescent color of the light emitter 24 of the air outlet 2.

Furthermore, in the light emission control device 25, when the light emitting body 24 of the air outlet 2 emits light in a color corresponding to the operating state, the current air volume control state is indicated by the amount of light emitted from the light emitting element 24 of the air outlet 2. It will be done. Thereby, the user can easily check the operating status of the air conditioning system 1 by visually checking the amount of light emitted from the light emitter 24 of the air outlet 2.

Furthermore, the light emission control device 25 causes the light emitting body 24 of the air outlet 2 to emit light in the fifth color when the air quality deteriorates. As a result, the deterioration of air quality in the current operating state is indicated by the color of the light emitted from the light emitter 24 at the air outlet 2. Thereby, the user can easily check the operating status including the operating status of the air conditioning system 1 by visually recognizing the luminescent color of the light emitter 24 of the air outlet 2.

In steps S2, S7, S8, and S9, as described above, if information to stop the execution of light emission control of the light emitter 24 is transmitted from the mobile terminal device 18, the light emission control of the light emitter 24 of the air outlet 2 is performed. Stop execution. If the mobile terminal device 18 transmits information to stop the execution of the light emission control of the light emitter 24, all steps S1 to S9 may not be executed.

In addition to the various sensors described above, an optical sensor is provided to detect the indoor brightness of the air-conditioned area, and the light emission control device 25 sends data on the indoor brightness detected by the optical sensor via the system control device 11. Alternatively, the light may be obtained directly from an optical sensor, and control may be executed to change the basic amount of light emitted by the light emitter 24 according to the current indoor brightness. For example, if the brightness in the room is brighter than the threshold, the basic light emission amount should be set brighter than the standard setting value, and if the indoor brightness is lower than the threshold value, the basic light emission amount should be set lower than the standard setting value. Bye. When performing such control, in steps S2, S7, S8, and S9, a process of changing the amount of light emission in accordance with a change in the standard setting value is executed.

Furthermore, as described above, even if the mobile terminal device 18 transmits information to stop the execution of the light emission control of the light emitter 24, when executing steps S1 to S9, steps S2, S7, and S9 are In this case, the execution of the light emission control may be stopped, and the light emission control may be executed in response to the warning in step S8. In this way, it is possible to warn the user about driving conditions related to the user's health condition, such as deterioration of air quality, by controlling the light emission of the light emitter 24. In this manner, the light emission control device 25 may stop at least part of the light emission control when the mobile terminal device 18 transmits information to stop the light emission control of the light emitter 24 . In this way, when the mobile terminal device 18 transmits information to stop the light emission control of the light emitters 24 and the light emission control device 25 stops at least part of the light emission control, the user can stop the light emission control of the light emitters 24. If such light emission control is unnecessary, such light emission control can be prevented from being executed, so that control of the light emission state of the light emitter 24 can be customized according to the user's judgment. Furthermore, power consumption can be reduced by stopping at least part of the light emission control.

Further, FIG. 4 shows an example in which the light emission control device 25 controls the color of the light emitted from the light emitter 24 according to the detected value of the temperature sensor 12. However, the present invention is not limited to this, and the light emission control device 25 may control the color of light emitted from the light emitter 24 according to the detected value of the humidity sensor 13.

Since the light emission control of the light emitter 24 provided at the air outlet 2 is easily visible to the user, it is possible to improve the user's recognition rate of driving conditions such as the driving mode. In addition, since the light emission control of the light emitter 24 provided at the air outlet 2 is easily visible to the user, it is possible to prevent the occurrence of poor ventilation due to the user forgetting to perform the ventilation operation, and to prevent infectious diseases caused by poor ventilation. The risk of infection can be suppressed.
