The indoor temperature detecting means 106 is sucked through the inlet port 3 to control the indoor temperature to the temperature Ts set by the user by the driving operation means 102 to perform the air cleaning operation of the air conditioner. The temperature Tr of the indoor air is sensed, and the outdoor temperature detecting means 108 detects the outdoor temperature To and outputs it to the control means 104.

In addition, the heater driving means 120 receives the control signal output from the control means 104 to heat the purified indoor air through the electrostatic precipitator 18 to drive control the electric heater 27, the compressor driving The means 122 controls the control means 104 according to the difference between the temperature Ts set by the user by the driving operation means 102 and the room temperature Tr sensed by the room temperature sensing means 106.

Hereinafter, the operation control device of the air conditioner configured as described above and the operational effects of the method will be described.

6 is a flowchart showing the operation control operation procedure of the air conditioner according to the present invention, in which S denotes a step.

First, when power is applied to the air conditioner, the power supply means 100 converts a commercial AC voltage supplied from an AC power terminal (not shown) into a predetermined DC voltage required for driving the air conditioner, thereby driving each circuit and control means ( Output to 104).

Therefore, in step S1, the DC voltage output from the power supply means 100 is input from the control means 104 to initialize the air conditioner.

At this time, when the user operates the operation operation means 102 and presses the operation key, and then inputs the operation mode (eg, the air cleaning mode) of the desired air conditioner, the operation selection signal and the operation selection signal from the operation operation means 102. An operation start signal (hereinafter referred to as an operation signal) is input to the control means 104.

Accordingly, in step S2, the control means 104 determines whether the driving signal is input from the driving operation means 102, and maintains the air conditioner in the operation standby state when the driving signal is not input (NO). The operation of step S2 and below is repeated.

As a result of the discrimination in step S2, when an operation signal is input (YES), the process proceeds to step S3 and the control means 104 determines whether the operation condition input by the operation operation means 102 is the air cleaning mode. If the air cleaning mode is not (NO), go to step S31 to determine the operating frequency of the compressor 33 according to the difference between the set temperature (Ts) and the room temperature (Tr) to perform the cooling operation of the air conditioner. While returning to step S3, the operation of step S3 or less is repeated.

As a result of the determination in step S3, in the case of the air cleaning mode (YES), to perform the air cleaning operation, the process proceeds to step S4 to sense the temperature To of the outdoor air in the outdoor temperature sensing means 108, and The means 104 receives analog data of the outdoor temperature To detected by the outdoor temperature detecting means 108 and converts the analog data into digital.

Subsequently, in step S5, the control means 104 has a predetermined temperature (T1; preset outdoor temperature for determining whether the room temperature is winter or summer temperature is high, about 10 ° C.) of which the outdoor temperature To is preset. Determine the authorization.

As a result of the determination in step S5, when the outdoor temperature To is equal to or higher than the predetermined temperature T1 (YES), it is determined that the room temperature is high, and the control means 104 proceeds to step S6 to perform the blowing air cleaning mode. ) Outputs control signals for driving the electrostatic precipitator 18 and the indoor fan motor 21 to the dust collecting driving means 128 and the indoor fan motor driving means 126.

Therefore, the dust collector driving means 128 drives the electrostatic precipitator 18 according to the control signal output from the control means 104, and the indoor fan motor driving means 126 controls the signal output from the control means 104. By controlling the rotation speed of the indoor fan motor 21 to drive the indoor fan (23).

When the electrostatic precipitator 18 and the indoor fan motor 21 are driven, in step S7, dust floating in the indoor air sucked through the suction port 3 is decomposed into fine particles in the precipitator 18 and ionized at the same time. Since the odor is removed while adsorbing and removing the dust on the dust collecting plate (not shown) having the opposite charge, the clean air is guided upward through the electrostatic precipitator 18 and discharged to the room through the discharge port 7. Perform.

In the blowing air cleaning operation of the air conditioner as described above, in step S8, the control means 104 determines whether the operation stop signal is input from the operation operation means 102, and when the operation stop signal is not input (NO In this case, the flow returns to the step S7, and the operation of the step S7 or less is repeated while continuing to perform the blowing air cleaning operation.

As a result of the discrimination in step S8, when the operation stop signal is input (YES), the control means 104 sends a control signal for stopping the electrostatic precipitator 18 and the indoor fan motor 21. Output to the dust collection driving means 128 and the indoor fan motor driving means (126).

Therefore, the dust collector driving means 128 turns off the electrostatic precipitator 18 by cutting off the power supply voltage applied to the electrostatic precipitator 18 under the control of the control means 104, and in the indoor fan motor driving means 126, While stopping the indoor fan motor 21 under the control of the control means 104, the control means 104 moves the air conditioner to the operation standby state until the operation signal is input again by the operation operation means 102. Returning to the step S2, the operation of step S2 or less is repeated while holding.

On the other hand, when the determination result in step S5 indicates that the outdoor temperature To is less than the predetermined temperature T1 (NO), it is determined that the room temperature is low, and the process proceeds to step S51 to perform the warm air cleaning mode. 104 is a dust collecting driving means 128, an indoor fan motor driving means 126, and a heater driving means 120 for controlling the control signals for driving the electric precipitator 18, the indoor fan motor 21 and the electric heater 27. )

Therefore, the dust collector driving means 128 drives the electrostatic precipitator 18 according to the control signal output from the control means 104, and the indoor fan motor driving means 126 controls the signal output from the control means 104. The indoor fan 23 is driven by controlling the rotation speed of the indoor fan motor 21, and the heater driving means 120 drives the electric heater 27 according to the control signal output from the control means 104. .

When the electrostatic precipitator 18, the indoor fan motor 21, and the electric heater 27 are driven, in step S52, dust floating in the indoor air sucked through the suction port 3 is converted into fine particles in the electrostatic precipitator 18. At the same time, the ions are removed while adsorbing and removing ionized dust on a dust collector plate (not shown) having a counter charge, so that clean air is guided upward through the electrostatic precipitator 18, and the air guided upward is an electric heater. Since the hot air is heated while passing (27), the warm air air cleaning operation is performed in which the warm air air purified through the discharge port 7 is discharged to the room.

In the warm air air cleaning operation of the air conditioner as described above, in step S53, the control means 104 determines whether the operation stop signal is input from the operation operation means 102, and when the operation stop signal is not input (NO In this case, the flow returns to step S52, and the operation of step S52 or less is repeated while continuing to perform the blowing air cleaning operation.

As a result of the discrimination in step S53, when the operation stop signal is input (YES), the flow advances to step S54, and the control means 104 controls the electric precipitator 18, the indoor fan motor 21 and the electric heater 18. The control signal for stopping is output to the dust collecting driving means 128, the indoor fan motor driving means 126, and the heater driving means 120.

Therefore, the dust collector driving means 128 turns off the electrostatic precipitator 18 by cutting off the power supply voltage applied to the electrostatic precipitator 18 under the control of the control means 104, and in the indoor fan motor driving means 126, The indoor fan motor 21 is stopped under the control of the control means 104, and the heater driving means 120 proceeds to step S10 while stopping the electric heater 27 under the control of the control means 104, and step S10. The following operation is repeated.
