Is a flow chart.

It is assumed that one or both of the air conditioner 2 and the air cleaner 3 are in operation as a condition under which the process of FIG. 3 is started. Further, when the operation unit 12 directly receives the interlock control of the air conditioning system 1 regardless of the operating conditions of the air conditioner 2 and the air cleaner 3, the process shown in FIG. To be done. In addition, ST described in the flowchart of FIG. 3 and FIG. 4 represents a step, and the number following this represents each step number.

In FIG. 3, the control unit 15 checks whether or not the setting operation to set the interlock control of the air conditioning system 1 to “valid” or “invalid” is received from the operation unit 12 (ST1). When the operation to set interlock control is not performed (ST1-No), it is checked whether a signal for stopping the operation of the air conditioner 2 or the air purifier 3 is received from the operation unit 12 (ST2). Note that the reception for stopping the driving includes, for example, the stopping of the scheduled driving by an off timer (not shown).

When the control unit 15 receives a stop of the operation of the air conditioner 2 or the air purifier 3 in ST2 (ST2-Yes), the setting state of interlocking control of the air conditioning system 1 stored in the storage unit 14 described later. Whether or not "valid" is checked (ST3). When the setting state of interlocking control is "valid" (ST3-Yes), the storage unit 14 stores which of the air conditioner 2 and the air purifier 3 is the target device that has received the stop of the operation (ST4) . Subsequently, the time counting unit 13 starts time counting (ST5). Then, it is checked whether the time kept by the clock unit 13 has reached a predetermined absence continuation time (for example, 10 minutes) preset as a threshold value for determining that a person is not present in the room. To do (ST6).

In ST6, when the time kept by the clock unit 13 does not reach the predetermined absence continuation time (ST6-No), the control unit 15 confirms whether or not the signal from the human detection unit 11 has been received. To do (ST7). If a signal for detecting a person is received (ST7-Yes), the clocking unit 13 stops the clocking of the clocked time and resets the clocking time (ST8). And it returns to ST5.

On the other hand, when the control unit 15 receives an operation for setting the interlocking control of the air conditioning system 1 from the operation unit 12 in ST1 (ST1-Yes), "valid" or "valid" as the setting state of the interlocking control according to the received operation. "Invalid" is stored in the storage unit 14 (ST9). And jump to ST2. As the setting state of the interlocking control, either “valid” or “invalid” is stored in advance in the storage unit 14 as an initial value of the air conditioning system 1.

Further, in ST3, when the setting state of the interlocking control of the air conditioning system 1 stored in the storage unit 14 is not "valid" ("invalid") in ST3 (ST3-No), the storage unit 14 The operation of the target device (the air conditioner 2 or the air purifier 3) having received the stop stored in the is stopped. Then, the interlock control of the air conditioning system 1 is not performed, and the processing before the start of the interlock control is ended.

In addition, when the control unit 15 does not receive a signal from the human detection unit 11 that has detected a human in ST7 (ST7-No), the control unit 15 returns to ST6. In ST6, the control unit 15 causes the time counting unit 13 to count time (the elapsed time when the absence state continues after the person is absent due to processing and determination from ST5 to ST8) is a predetermined absence continuation time If reached (ST6-Yes), the process jumps to the process of interlocking control of the air conditioning system 1 according to the present invention shown in FIG.

In FIG. 4, the control unit 15 starts the blowing of the strong air flow that raises the dust accumulated in the room from the blowing unit 21 (ST21). Further, in parallel with the above-described processing of ST21, the dust collection unit 31 starts a dust collection operation for collecting dust in the air (ST22). Subsequently, the timing unit 13 starts timing of the interlocking control time (ST3). And it is confirmed whether the signal which detected the person from the person detection part 11 was received (ST24).

When the control unit 15 does not receive a signal from the human detection unit 11 for detecting a human being in ST24 (ST24-No), the elapsed time of interlocking control being clocked by the timekeeping unit 13 causes dust in the room to soar. It is checked whether a preset predetermined time (for example, 30 minutes) required to collect dust is reached (ST 25). When the elapsed time of interlocking control reaches a predetermined time (ST25-Yes), it is checked whether the target device that has received the stop of the operation stored in the storage unit 14 is the air conditioner 2 (ST26) .

In ST26, the control unit 15 receives the operation stop stored in the storage unit 14 when the target device receiving the operation stop stored in the storage unit 14 is not the air conditioner 2 (ST26-No). It is checked whether the target device is the air purifier 3 (ST27). If the target device that has received the stop of the operation stored in the storage unit 14 is the air purifier 3 (ST27-Yes), the operation of the air purifier 3 is stopped (ST28). Subsequently, the timing of the elapsed time of interlocking control being clocked by the clock unit 13 is stopped, and the clocking time is reset (ST29). Then, the processing of interlocking control of the air conditioning system 1 is ended.

On the other hand, when the control unit 15 receives a signal of detecting a person from the human detection unit 11 in ST24 (ST24-Yes), the blower unit 21 starts the ST21 to start the dust accumulated in the room. Stop the air flow (ST30). And it jumps to ST26. In ST25, when the elapsed time of the interlocking control being timed by the timer unit 13 has not reached the predetermined time in ST25 (ST25-No), the control unit 15 returns to ST24.

Further, in ST26, when the target device that received the stop stored in the storage unit 14 is the air conditioner 2 (ST26-Yes) in ST26, the control unit 15 stops the operation of the air conditioner 2 (ST31). And it jumps to ST29. Further, in ST27, in the case where the target device having received the stop stored in storage unit 14 is not air cleaner 3 (operation unit 12 directly receives interlock control of air conditioning system 1) (ST27). -No) Jump to ST29.

By performing the interlocking control process of the air conditioning system 1 described in FIGS. 3 and 4, the air flow blown out from the air blowing unit 21 of the air conditioner 2 causes dust accumulated in the room to soar, and soars. Can be collected by the dust collection unit 31 of the air cleaner 3.
