FIG. 5 is a flowchart of the sleep mode, and FIG. 6 is a flowchart of the irrigation mode.

(Normal operation mode)
First, as shown in FIG. 2, the control means 6 controls the operation of the ventilation fan 4 and the supply device 3 in principle in the normal operation mode during the daytime or during working hours when the installation location is an office or the like. It will be.

  Specifically, first, the normal operation mode is selected by turning on the air purification greening device 1 (or the normal operation mode may be automatically selected when the switch is turned on).

  Next, in the normal operation mode, as shown in FIG. 3, first, in step 1 (S1), the ventilation fan 4 is started to operate at a preset standard rotational speed. As described above, since the rotation speed (air flow rate) of the ventilation fan 4 can be set in multiple stages, differences in the installation environment such as outdoors and indoors (indoors, office space and pollution) Depending on the installation environment such as non-smoking rooms where the substance concentration is high), the rotation speed (aeration amount) to be used as the standard rotation speed is determined and set.

Next, if the preset standard rotation speed (standard rotation speed when the operation mode is selected) is not suitable for the installation environment, manually change the rotation speed stage to the installation environment. A suitable rotation speed is set to the standard rotation speed.
Next, an operation is performed at the set standard rotational speed, and it is determined in step 2 (S2) whether or not the measured value of the moisture sensor 5 (moisture content of the planting unit 2) is equal to or greater than the set value. And when a moisture content is less than a preset value, the supply apparatus 3 is operated, water and nutrient solution are supplied to the planting part 2, and it returns to step 2 (S2) again.

  Next, when the measured value of the moisture sensor 5 is greater than or equal to the set value (when greater than the set value), it is determined in step 3 (S3) whether or not a contaminant sensor is provided, and the contaminant is determined. If a sensor is provided, it is determined in step 4 (S4) whether or not a contaminant is detected. Then, when a contaminant is detected, the rapid operation mode to be described later is selected. When the contaminant is not detected, the process proceeds to step 5 (S5), and the time for shifting to the preset pause mode has elapsed. If the set time has elapsed, the ventilation fan 4 is stopped and a transition is made to a sleep mode to be described later. If the set time has not elapsed, step 2 is performed. Return to (S2).

  Next, if no contaminant sensor is provided in step 3 (S3), it is determined in step 6 (S6) whether a human sensor or a thermo sensor is provided, and the human sensor or thermo sensor is determined. In step 7 (S7), it is determined whether or not a person or a temperature rise has been detected (is the installation temperature or higher). Then, when a person or temperature rise is detected, the rapid operation mode described later is selected, and when no person or temperature rise is detected, the process proceeds to step 8 (S8) to shift to a preset sleep mode. When the set time has elapsed, the ventilation fan 4 is stopped and the operation mode is changed to the sleep mode described later, and the set time has not elapsed. Will return to step 2 (S2).

  Next, when a human sensor or a thermo sensor is not provided in step 6, it is determined whether or not the time set by the timer has elapsed in step 9 (S9), and the set time has elapsed. In this case, the rapid operation mode to be described later is selected, and if the set time has not elapsed, the process proceeds to step 10 (S10), and whether or not the time for shifting to the preset pause mode has elapsed. If the set time has elapsed, the ventilation fan 4 is stopped and the operation proceeds to a sleep mode to be described later. If the set time has not elapsed, the process returns to step 2 (S2). It will be. That is, when no pollutant sensor or human sensor is provided, the mode is periodically shifted to the rapid operation mode.

(Rapid operation mode)
When the rapid operation mode is selected, it is first determined in step 11 (S11) whether or not a photocatalyst unit is provided. When the photocatalyst unit is provided, the photocatalyst unit is operated and the normal operation mode is selected. The process returns to (Step 2 (S2)). Specifically, the light source is turned on, the ventilation fan 4 is operated at a rotational speed higher than the standard rotational speed for a predetermined time, and then the light source is turned off.

  Next, when the photocatalyst unit is not provided, the ventilation fan 4 is operated at a rotational speed higher than the standard rotational speed for a predetermined time, and then returns to the normal operation mode (step 2 (S2)).

(Pause mode)
When the sleep mode is selected, it is first determined in step 12 (S12) whether it is nighttime or outside working hours (or whether it has been operated for a certain period of time in normal operation mode), and at night or outside working hours. If it is (or if it has been operating for a certain period of time in the normal operation mode), it proceeds to step 13 (S13), and if it is not at night or outside working hours (or if it has not been operating for a certain period of time in the normal operation mode), it is predetermined. After the time elapses, the process returns to step 12 (S12) again.

  Next, in step 13 (S13), it is determined whether or not the preset irrigation time has elapsed. If the set time has elapsed, the irrigation mode will be described later. If it has not elapsed, the process returns to step 13 (S13) again after a predetermined time has elapsed.

  In addition, it is also possible not to provide the irrigation mode (step 13 (S13)). In that case, when it is nighttime or outside working hours in step 12 (S12) (or when it operates for a certain period of time in the normal operation mode). Returns to the normal operation mode (step 2 (S2)) after a predetermined time has passed after passing through step 13 (S13).

  In addition, since the sleep mode is a mode that is selected during non-working hours such as at night or on holidays, as a rule, no water or nutrient solution is supplied to the planting unit 2, but holidays continue. For example, step 2 (S2) can be added between step 12 (S12) and step 13 (S13) as necessary to check the amount of water and operate the supply means.

(Irrigation mode)
When the irrigation mode is selected, first, in step 14 (S14), it is determined whether or not the measured value of the moisture sensor 5 (moisture content of the planting unit 2) is equal to or greater than a set value. And when the moisture content is less than the set value, the supply device 3 is operated to supply water or nutrient solution to the planting unit 2, and after a predetermined time has passed, the process returns to step 14 (S14) again. Become.

  Next, when the measured value of the moisture sensor 5 is equal to or greater than the set value (when equal to or greater than the set value), the process returns to the normal operation mode (step 2 (S2)).

  Thus, by adding the irrigation mode to the end of the dormant mode, it is possible to more effectively prevent plant death.

  Therefore, in this operation (control method), the minimum necessary air purification greening device is operated, and efficient air purification is performed.

(Operation (control method) when controlling multiple units, 2)
Next, as another example of controlling a plurality of the air purification greening devices 1 according to the present invention, as shown in FIG. 8, the air purification greening device 1 located in the vicinity of the source of contaminants such as tobacco. In other words, it works as one.
In order to perform this operation, the control means 6 of each air purification and greening device 1 has a communication function for mutually transmitting and receiving the measurement results of the respective moisture sensors 5 and the rotational speed information of the ventilation fan 4. There must be. Moreover, the control means 6 of each air purification greening device 1 has received other air purification greening devices received by each air cleaning greening device 1 in addition to the measurement results of the respective moisture sensors 5 and the rotational speed of the ventilation fan 4. It is necessary to perform control in consideration of the measurement result of one moisture sensor 5 and information on the rotational speed of the ventilation fan 4.

  And about the operation | movement (control method) of the air purification greening apparatus 1 used as the object in this case, about operation | movement (control method) of the air purification greening apparatus 1a located in the shortest distance first, [0033]-[0048] mentioned above. ] Will be controlled. Moreover, the information of the rotation speed of the ventilation fan 4 is transmitted to the adjacent air purification greening device 1.

  Next, regarding the operation (control method) of the air purification greening device 1b adjacent to the air purification greening device 1a located at the shortest distance, a ventilation fan is received by receiving a signal from the air purification greening device 1a located at the shortest distance. The control of [0033] to [0048] is performed by setting the rotational speed of 4 to a stage (rotational speed) that is one or two steps lower than the rotational speed of the ventilation fan 4 of the air cleaning greening device 1a located at the shortest distance. Will be. Moreover, the information of the rotation speed of the ventilation fan 4 is further transmitted to the adjacent air purification greening device 1.

  Next, regarding the operation (control method) of the air purification greening device 1c further adjacent to the “adjacent air purification greening device 1b”, a ventilation fan is received by receiving a signal from the “adjacent air purification greening device 1b”. The control of [0033] to [0048] is performed by setting the rotational speed of 4 to a stage (rotational speed) that is one or two steps lower than the rotational speed of the ventilation fan 4 of the “adjacent air cleaning greening device 1b”.

(Operations when controlling multiple units (control method), 3)
Next, as another example of controlling a plurality of the air purification greening devices 1 according to the present invention, the operation (control method) shown in FIG. 8 is developed, and greening is performed in addition to air purification. While considering the water content of the planting part 2 which is important in the air purification planting apparatus 1 which is also intended to perform, the plurality of air purification planting apparatuses 1 are controlled more efficiently.

Specifically, for example, when the operation (control method) as shown in FIG. 7 or FIG. 8 is performed, the rotation speed of the ventilation fan 4 is set when the air cleaning greening device 1a located at the shortest distance is in the rapid operation mode. The amount of air passing through the planting part 2 increases, and the moisture in the planting part 2 evaporates (the amount of water decreases). Here, if the operation in the rapid operation mode is short, there is no problem because water or nutrient solution is supplied from the supply device 3 in step 2 (S2). In an installation environment that requires a long time (installation environment in which the rapid operation mode is selected for a long time), the planting part 2 of the air purification planting device 1a located at the shortest distance as described above A lot of air always passes and water and nutrient solution are always supplied. If this state is maintained, plant growth is hindered and the purpose of greening cannot be achieved.
Therefore, about the operation | movement (control method) shown in FIG. 9, considering the moisture content of the planting part 2, the several air purifying greening apparatus 1 will be controlled more efficiently.

  In order to perform this operation as well, the control means 6 of each air purification and greening device 1 has a communication function for mutually transmitting and receiving the measurement results of the respective moisture sensors 5 and the rotational speed information of the ventilation fan 4. There must be. Moreover, the control means 6 of each air purification greening device 1 has received other air purification greening devices received by each air cleaning greening device 1 in addition to the measurement results of the respective moisture sensors 5 and the rotational speed of the ventilation fan 4. It is necessary to perform control in consideration of the measurement result of one moisture sensor 5 and information on the rotational speed of the ventilation fan 4.

  Specifically, the normal operation mode (for example, the rotational speed level 1) is first selected by starting all the air purification greening devices 1, and the control of the above [0033] to [0048] is started. Become.

  Next, when a pollutant or the like is detected, the rapid operation mode (for example, in step 3 (S3) or step 6 (S6) or step 9 (S9)) is first performed in the air purification greening device 1a located at the shortest distance. , The rotation speed level 3) is selected.

  Next, as shown in FIG. 9, in this operation (control method), each air clean greening as shown in FIG. 10 based on the moisture content of the planting part 2 of the air clean greening device 1a located at the shortest distance. The rotational speed of the ventilation fan 4 of the apparatus 1 is controlled.

  First, as shown in FIG. 10, it is determined whether or not the measured value of the moisture sensor 5 (moisture content of the planting unit 2) is equal to or greater than the first set value in the air clean greening device 1a located at the shortest distance ( Step 15 (S15)). Here, the first set value may be the value set in step 2 (S2), but in order to perform more efficient control, the planting unit 2 needs a minimum amount of water for cleaning. A set value is preferable.

If the moisture content is less than the first set value, a signal is transmitted to the control means 6 of the adjacent air purification greening devices 1b, 1c, and the adjacent air purification greening device 1b, which has received such information, The control means 6 of 1c starts the control which makes the rotational speed one or two steps higher than the speed control in the rapid operation mode or the normal operation mode.
In addition, the air purification and greening device 1a located at the shortest distance from which the signal is transmitted operates by reducing the rotational speed of the ventilation fan 4 to the rotational speed of the normal operation mode.
That is, in this operation, with respect to the air purification planting device 1a located at the shortest distance, the reduction of the cleaning function due to the drying of the planting part 2 or the plant rather than the maximization of the air flow utilizing the merit located at the shortest distance Therefore, when the moisture content is less than the first installation value, control is performed to suppress the ventilation rate. In addition, when performing a driving | running | working at the rotation speed, step 2 (S2) performed in normal operation mode is performed (operating the supply apparatus 3 and supplying water and nutrient solution to the planting part 2). You can also.

Next, when the measured value of the moisture sensor 5 (moisture content of the planting part 2) is not less than the first set value in step 15 (S15), the measured value of the moisture sensor 5 (in step 16 (S16)) ( It is determined whether the water content of the planting part 2 is equal to or greater than the second set value. Here, the second set value is set to a set amount that is such that the amount of water in the planting unit 2 does not fall below the first set value when the ventilation fan 4 is operated for 1 minute at the maximum amount of ventilation (number of rotations). become.
That is, after confirming that the planting unit 2 can secure the minimum amount of water necessary for cleaning even when the ventilation amount is maximized, the rapid operation of the air purification planting apparatus 1a located at the shortest distance is performed. Control to maintain the operation mode is performed.

  Next, when the amount of water is less than the second set value, a signal is transmitted to the control means 6 of the adjacent air purification greening devices 1b and 1c, and the adjacent air purification greening device 1b that has received such information is received. The control means 6 of 1c starts the control in the rapid operation mode or the rotational speed higher by one or two steps than the rotational speed in the normal operation mode. In addition, the air cleaning and greening device 1a located at the shortest distance from which the signal is transmitted operates with the rotational speed of the ventilation fan 4 set to a rotational speed (for example, rotational speed level 2) that provides a one-stage higher ventilation rate than the normal operation mode. Will do.

Next, when the measured value of the moisture sensor 5 (moisture content of the planting unit 2) is equal to or greater than the second set value in step 16 (S16), any adjacent air purification greening in step 17 (S17) It is determined whether or not the rotational speed of the ventilation fan 4 of the devices 1b and 1c is the rotational speed of the rapid operation mode (for example, rotational speed level 3), and the air purification greening that is operated at the rotational speed of the rapid operation mode When the devices 1b and 1c are present, the operation is performed with the rotational speed of the ventilation fan 4 set to a rotational speed (for example, rotational speed level 2) that provides a ventilation amount that is one step higher than the normal operation mode.
That is, when the adjacent air purification greening devices 1b and 1c are operated in the rapid operation mode, the air purification greening device 1a located at the shortest distance only slightly increases the rotational speed of the ventilation fan 4 (rapid By avoiding the operation in the operation mode as much as possible, the air purification is controlled by using the plurality of air purification greening devices 1 as a unit.

  Next, when there is no air purification greening device 1 that is operated at the rotational speed of the rapid operation mode in step 17 (S17), a quick cleaning operation is necessary, so that the adjacent air purification greening devices 1b, 1c are required. The control means 6 of the adjacent air purification and greening apparatuses 1b and 1c that have received the information is transmitted to the control means 6 and starts control in the rapid operation mode. Moreover, the operation | movement by rapid operation mode is maintained also about the air purifying greening apparatus 1a located in the shortest distance.

  Therefore, in this operation (control method), a plurality of air purification greening apparatuses 1 operate in cooperation with each other as shown by the dotted line in FIG. Air purification will be performed.

  The air purification greening device and the control method of the air purification greening device of the present invention can be used for outdoor and indoor air purification and greening.
