Repeat the operation. When the operation switch is turned on (YES) in step S2, the fan motor is driven by the driving frequency output from the indoor unit microcomputer 47 in step S3, and the compressor starts operation in step S4. In step S5, it is determined whether the air freshener discharge operation, the insecticide spraying operation or the air conditioner performs normal operation of cooling / heating, and when it is determined that the air freshener discharge command is input in the step S5 (in the direction), in step S6 The fragrance unit is turned on, and the flow proceeds to step S7 to perform direction operation.

Then, when the direction operation is performed in step S7 and a predetermined time has passed, the flow proceeds to step S8 to receive the indoor air detection sensor 45 receiving the detected data of the indoor air detected by the indoor comfort sensor 45 to determine whether the indoor air is comfortable. If it is comfortable (YES), the flow proceeds to step S9 to block the output of the control signal from the output terminal O of the indoor unit microcomputer 47 to turn off the output signal of the control means 53 to turn off the fragrance unit 26. To stop the operation of the heater 26c to end the perfume operation.

On the other hand, if the indoor air is not comfortable (NO at step S8), the flow proceeds to step S10 to increase the heating voltage of the heater 26c of the perfume unit 26 to increase the calorific value of the heater 26c, thereby discharging the perfume. Is increased, and the flow returns to step S8 to repeat the operations of step S8 and below.

On the other hand, if it is determined that the operation command determined in step S5 is an insecticidal operation command, the flow advances to step S11 to output a control signal from the indoor unit microcomputer 47 to operate the switching means 59 to control the control valve 34 of the pesticide spraying unit 30. Open).

Next, in step S12, the insecticidal operation is carried out. In step S13, it is determined whether a predetermined time has elapsed. If a predetermined time has elapsed (YES), the process proceeds to step S14 to turn off the pesticide spraying unit 30 to control valves. The insecticide operation is terminated by crossing 34.

On the other hand, when a predetermined time has not elapsed in the step S13 (NO), the operation of step S13 is repeated.

Further, if it is determined that the operation is normal in step S5, normal operation is performed, and the flow proceeds to step S15 to receive the indoor temperature sensing data from the indoor temperature detecting unit 43 from the indoor microcomputer 47 to determine whether the indoor air is comfortable and to make it comfortable. If it is (YES), continue to operate the air conditioner in that state or terminate the operation of the air conditioner.

On the other hand, when the indoor temperature data detected in step S15 is not comfortable (NO), the operation of step S3 or less is repeated.

The above description will be described in detail with reference to FIG. 4. First, whether the direction control is to be strong or slow is determined by the rotational speed RPM of the fan motor 51, and the fan motor 51 When the strength and weakness of the fragrance combustion control is determined by the rotation speed (RPM) of the fragrance combustion operation is performed for a predetermined time.

In FIG. 4 (b), the rotation speed (RPM) of the fan motor 51 is changed from the low speed to the high speed by the first speed E ', the second speed D', the third speed C ', If the fan motor 51 is operating at the fastest fifth speed A 'while the fourth speed B' and the fifth speed A 'are set, the air freshener unit 26 of FIG. Or if the indoor fan is operating at the slowest speed at the first speed E 'to operate the control means 53 for operating the insecticide spraying unit 30, the fragrance unit 26 Alternatively, in order to operate the switching means 59 for operating the pesticide spraying unit 30, triggering at the point E of FIG. 4 (a) to generate heat at the heater 26c and the control valve 34 of the pesticide spraying unit 30. ), The variable control to open, enables the direction operation for a predetermined time, and after a predetermined time to notify the completion of the operation by the alarm function not shown. As described above, of course, the trigger is activated to operate the heater 26c or the control valve 34 of the units 26 and 30 at points B to D of FIG.

As another example, a powerful direction combustion operation is possible by heating the heater 26c at the Z point of FIG. 4 (a) regardless of the rotational speed (RPM) of the fan motor 51 by controlling the direction continuously. You can also

As described above, according to the air conditioner and the control method of the air freshener and the insecticide spraying unit of the present invention, the insecticide spray which can be used by filling the air freshener unit and the liquid insecticide which can attach and detach the solid air freshener to the air conditioner By installing a unit, air fresheners are mixed with air fresheners to remove odors such as CO ₂ and ammonia gas contained in indoor air, and to aromatize indoor air or spray insecticides to kill insects such as mold, flies and mosquitoes. In order to maintain comfortable indoor air, and to perform the insecticidal function, the air conditioner does not use the control circuit using high pressure discharge, but the stable control circuit using the triac and phototriac elements, which are power control elements, is used. This makes it easy to keep indoor air comfortable and There is an excellent effect capable of preventing the erroneous operation of the indoor unit microcomputer that was generated at the time of discharge.
