FIG. 1 is a control block diagram and FIG. 2 is a flowchart.
The structure of the air conditioner is the same as the conventional one shown in FIG. As shown in FIG. 1, the output of the operation switch 36 of the air cleaning device 10 is input to the operation / stop means 43 of the air cleaning device of the control device 30. Here, the air cleaning device 10 is turned on / off based on ON / OFF of the operation switch 36. It will be decided to start or stop. The detection value of the dirt sensor 35 is input to the storage means 40 and stored therein, and at the same time is input to the comparison means 41, where the setting means is set.
The set value input from 42 is compared. As a result of the comparison, if the detected value is equal to or larger than the set value, the operation / stop means 43 of the air cleaning device receives the output of the comparing means 41 and determines the operation of the air cleaning device. The result is output to the air cleaning device 10, and the air cleaning device 10 starts operation. At the same time, this determination result is output to the timer 45, and the timer 45 starts counting. When the time set in the timer 45 has passed, that is, when the air cleaning device 10 is operated for a predetermined time, the timer
45 instructs the improvement degree determination means 46 to that effect. Then,
The improvement degree judging means 46 compares the detection value input from the dirt sensor 35 with the dirt degree stored in the storage means 40 to judge the change rate of dirt, that is, the improvement degree. Here, when it is determined that the degree of improvement is less than or equal to the set value set by the setting means 47, the result of this determination is the operation / stop means 43 of the air cleaning device.
The operation / stop means 43 decides to stop the air cleaning device. The above determination result is input to the ventilator actuation means 48, where the actuation of the ventilator is determined. The result of this determination is output to the ventilation damper 49 such as the exhaust damper 13, the inside / outside air switching damper 9, the power window device, and the indicator. Thus, one or more of the ventilation means 49 are activated, the exhaust damper 13 is opened, the inside / outside air switching damper 9 is switched to the outside air introduction, the window is opened by the power window device, and the indicator installed on the control panel is ventilated. Indicates that is required.

At 102, it is confirmed whether or not the degree of contamination is equal to or more than a predetermined value, and if so, at step 103, the air cleaning device 10 starts operation. Next, in step 104, it is confirmed whether or not a predetermined time has elapsed, and if it has elapsed, the dirt sensor 35 detects the degree of dirt in the vehicle interior air in step 105. Next, in step 106, it is confirmed whether or not the degree of improvement of dirt is equal to or more than a predetermined value, and if not, the air cleaning device is stopped in step 107, and then the ventilation means is operated in step 108. If No at Step 102 and Step
If YES is determined in 106, the process returns to step 101.
After step 108, the process proceeds from step 109 to the next control routine.
