(Embodiment 1)
FIG. 1 is a control block diagram of the air conditioner according to Embodiment 1 of the present invention. In FIG. 1, the off timer means 1 always compares the timer set value with the operation time, and sends a stop signal for the air conditioner to the control means 9 when the timer set time is reached. After receiving this stop signal, the operation of the air conditioner is determined according to the human body temperature detecting means 2, the outside air temperature detecting means 3, and each detected value. About the air conditioner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  FIG. 2 is a flowchart showing the operation of the air conditioner according to Embodiment 1 of the present invention. In step 1 and step 2, the cut-off timer time is determined. If the timer time is reached, the air conditioner is stopped in step 3. In step 4, the temperature near the human body is detected. At this time, if the temperature in the vicinity of the human body is lower than the predetermined temperature T1 ° C., it is not necessary to operate the air conditioner. Therefore, in step 6, the stop state by the timer operation is continued. If the temperature in the vicinity of the human body is higher than the predetermined temperature T1 ° C., the outside air temperature is determined in step 5. At this time, if the outside air temperature is higher than the predetermined temperature T2 ° C., it is determined that the air conditioning load is large after the turn-off timer operation, and the air conditioner is cooled in step 7. On the other hand, if the outside air temperature is lower than the predetermined temperature T2 ° C., the indoor high temperature air is discharged to the outside in step 8 and the ventilation operation is performed to introduce the outdoor low temperature air. Further, in step 9, the degree of dirt in the outside air is determined. If the degree of dirt is high, an air cleaning operation is performed. As a result, indoor high temperature air can be discharged to the outside, and outdoor low temperature air can be introduced indoors to lower the room temperature, and dirty outdoor air can be cleaned by performing an air cleaning operation. .
