As an initial condition for describing the operation of the present invention, it is assumed that the discharge port door 13 and the horizontal blade 35 are closed.

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, the user inputs the operation mode (automatic, cooling, dehumidification, ventilation, heating, etc.) and the set temperature (Ts) of the desired air conditioner by operating the operation operation means 102, and then press the operation key, the operation operation An operation selection signal and an operation start signal (hereinafter referred to as an operation signal) are input from the means 102 to the control means 104.

Accordingly, in step S2, the control means 104 determines whether the driving signal is input, and if the driving signal is not input (NO), the operation of step S2 or less is repeated while maintaining the air conditioner in the operating standby state. Perform.

As a result of the discrimination in step S2, when the operation signal is input (YES), the control means 104 proceeds to step S3 and the control means 104 opens a control signal for opening the closed discharge port 7; )

Accordingly, the door motor driving means 108 is coupled to the shaft 22 of the door motor 21 while the door motor 21 is driven in the forward direction by driving the door motor 21 under the control of the control means 104. The pinion 23 is rotated downward along the rack 23 in conjunction with the pinion 23 to move the discharge port door 13 downward to open the discharge port 7.

Subsequently, in step S4, the position of the discharge opening door 13 moved downward by the driving of the door motor 21 is detected by the door opening and closing detecting means 110, and the control means 104 detects the door opening and closing means ( In response to the signal sensed by 110, it is determined whether the discharge port 7 is completely opened.

As a result of the discrimination in step S4, when the discharge port 7 is not fully opened (NO), the door motor 21 is continuously driven until the discharge port door 13 is fully opened by returning to the step S3. When the discharge opening 7 is completely open (YES), the process proceeds to step S5, and the door motor driving means 108 stops driving the door motor 21 under the control of the control means 104, thereby discharging the door opening ( Complete the opening operation of 13).

Subsequently, the control means 104 outputs the control signal for opening the closed horizontal blade 35 to the blade motor driving means 112 in step S6.

Accordingly, in the blade motor driving means 112, the plurality of link members 29 are interlocked by driving the blade motor 27 under the control of the control means 104 so that the plurality of horizontal blades 35 are simultaneously opened.

At this time, in step S7 the position of the horizontal blade 35 that is opened by the drive of the blade motor 27 is detected by the blade opening and closing detecting means 114, the control means 104 by the blade opening and closing detecting means (114). It is determined whether the horizontal blade 35 is opened by receiving the sensed signal.

As a result of the discrimination in step S7, when the horizontal blade 35 is not opened (NO), the flow returns to the step S6 to continue driving the blade motor 27 until the horizontal blade 35 is fully opened, When the horizontal blade 35 is opened (YES), the process proceeds to step S8, and the blade motor driving means 112 stops the driving of the blade motor 27 under the control of the control means 104. Complete the opening operation of.

When the horizontal blade 35 is completely open, the horizontal blade 35 is a state in the center.

Subsequently, in step S9, the fan motor driving means 118 drives the indoor fan 33 by controlling the rotation speed of the indoor fan motor 119 under the control of the control means 104.

The driving condition of the compressor 117 is a case in which the room temperature Tr sensed by the room temperature detecting means 106 is greater than the temperature Ts set by the user during the cooling operation. The room temperature Tr sensed by the room temperature detecting means 106 is smaller than the temperature Ts set by the user.

As a result of the discrimination in step S10, when it is not the driving condition of the compressor 117 (NO), the flow returns to the step S9 and repeats the operation of step S9 or less while continuing to sense the room temperature Tr. In the case of the driving condition of the compressor 117 (YES), the control means 104 determines the operating frequency of the compressor 117 according to the difference between the room temperature Tr and the set temperature Ts. The control signal for driving the compressor 117 is output to the compressor driving means 116.

Accordingly, the compressor driving means 116 drives the compressor 117 according to the operating frequency determined by the control means 104.

Heat is exchanged by cold air or warm air by the latent heat of evaporation of the refrigerant flowing in the heat exchanger 31 while passing through the air 31.

The air heat-exchanged by the cold or warm air in the heat exchanger 31 is moved upward and the discharge air direction is adjusted to the left and right according to the wind direction angle of the vertical blade 11 rotatably installed in the discharge hole 7 and at the same time the According to the vertical swing of the horizontal blade 35 installed to the outside, the air direction angle of the air discharged through the discharge port 7 becomes wider by increasing the wind direction angle of the discharged air. Perform.

In the normal operation of the air conditioner as described above, in step S13, the control means 104 determines whether the operation stop signal is input by turning off the operation key of the operation operation means 102, and when the operation stop signal is not input. In the case of NO, the process returns to the step S12 and continues the normal operation and repeats the operation of the step S12 or less.

As a result of the discrimination in step S13, when the operation stop signal is input (YES), the control means 104 advances the control signal for stopping the compressor 117 and the indoor fan motor 119. Output to the drive means 116 and the fan motor drive means (118).

Accordingly, the compressor driving means 116 stops the compressor 117 under the control of the control means 104, and the fan motor driving means 118 controls the indoor fan motor 119 under the control of the control means 104. To stop the driving of the indoor fan 33.

Subsequently, in step S15, the control means 104 outputs a control signal for closing the horizontal blade 35 to the blade motor driving means 112 so that the closing operation of the discharge port door 13 is smoothly performed.

Accordingly, the blade motor driving means 112 drives the blade motor 27 according to the control of the control means 104, so that the plurality of link members 29 are interlocked to close the plurality of horizontal blades 35 at the same time. .

At this time, in step S16, the blade opening and closing detecting means 114 detects the position of the horizontal blade 35 that is closed according to the driving of the blade motor 27, and in the control means 104 by the blade opening and closing detecting means 114. The horizontal blade 35 is closed by receiving the detected signal.

As a result of the discrimination in step S16, when the horizontal blade 35 is not closed (NO), the process returns to the step S15 to continue driving the blade motor 27 until the horizontal blade 35 is completely closed, If the horizontal blade 35 is closed (YES), the process goes to step S17 and the blade motor driving means 112 stops the driving of the blade motor 27 according to the control of the control means 104 and the horizontal blade 35 Completes the closing operation.

Subsequently, in step S18, the control means 104 outputs a control signal for closing the discharge port 7 which is open to the door motor driving means 108.

Therefore, the door motor driving means 108 is coupled to the shaft 22 of the door motor 21 while the door motor 21 is driven in the reverse direction by driving the door motor 21 under the control of the control means 104. The pinion 23, which is connected to the pinion 23, rotates upward along the rack 23 to move the discharge port door 13 upward to close the discharge port 7.

At this time, in step S19 the position of the discharge port door 13 moved upward by the drive of the door motor 21 is detected by the door opening and closing detecting means 110, the control means 104, the door opening and closing detecting means ( It is determined whether the discharge port 7 is completely closed by receiving the signal sensed by 110.

As a result of the discrimination in step S19, when the discharge port 7 is not completely closed (NO), the door motor 21 is continuously driven until the discharge port door 13 is completely closed by returning to the step S18. When the discharge port 7 is completely closed (YES), the process proceeds to step S20 and the door motor driving means 108 stops driving the door motor 21 under the control of the control means 104 to discharge the door door ( The closing operation of 13) is completed.

Subsequently, in step S21, the control means 104 returns to the step S2 while maintaining the air conditioner in the operation standby state until the operation signal is input again by the driving operation means 102, and repeats the operation of step S2 or less. Perform.
