Hereinafter, the effect of the discharge airflow control device and method of the air conditioner configured as described above will be described.

4A and 4B are flowcharts showing the operation procedure of the discharge airflow control of the air conditioner according to the present invention. In Figs. 4A and 4B, 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 ( 116).

Therefore, in step S1, the DC voltage output from the power supply means 100 is input from the control means 116 to initialize the air conditioner.

At this time, when the user operates the operation operation means 102 and presses the operation key and inputs the set temperature Ts, the set air volume and the set direction of the room to be cooled or heated, the operation selection signal from the operation operation means 102. And an operation start signal are input to the control means 116.

Accordingly, in step S2, the control means 116 determines whether the operation key is on. If the operation key is not on (NO), the control means 116 keeps the air conditioner in operation standby until the operation key is on. Repeat the operation below S2.

As a result of the discrimination in step S2, when the operation key is turned on (YES), the flow advances to step S3, and the control means 116 transmits a control signal for driving the indoor fan motor 129 to the fan motor drive means 128. Output

Therefore, the fan motor driving means 128 controls the rotation speed (speed) of the indoor fan motor 129 according to the set air volume input by the driving operation means 102 to drive the indoor fan 17.

When the indoor fan 17 is driven according to the set air volume, the indoor air is sucked into the indoor unit 1 through the suction port 3, at which time the temperature Tr of the indoor air sucked through the suction port 3 is room temperature. The sensing means 118 detects and outputs the control means 116.

Subsequently, in step S4, the control means 116 adjusts the wind direction angles of the up-down wind vane 11 and the left-right wind vane 13 according to the set wind direction inputted by the driving operation means 102. The control signal for driving the 125 and 127 is output to the up and down and left and right wind direction control units 124 and 126.

Accordingly, the up and down and left and right wind direction adjusting units 124 and 126 receive control signals output from the control means 116 and drive the up and down and left and right wind stepping motors 125 and 127 to control the up and down wind vane 11 and the left and right wind vane 13. Adjust the wind angle according to the wind direction set by the user.

Subsequently, in step S5, the indoor temperature Tr sensed by the indoor temperature detecting means 118 is compared with the temperature Ts set by the user to the operation operation means 102 to determine whether the compressor 121 is a driving condition. Determine.

The driving condition of the compressor 121 is a case in which the room temperature Tr sensed by the room temperature sensing means 118 is greater than the set temperature Ts in the cooling operation, and the room temperature (in the heating operation). The case where Ts) is smaller than the set temperature Tr is described. In the present invention, the cooling or heating operation will be described as an example.

As a result of the discrimination in step S5, when it is not the driving condition of the compressor 121 (NO), the flow returns to the step S3 and repeatedly performs the operation of step S3 or less while continuously detecting the room temperature Tr, In the case of the driving condition of the compressor 121 (YES), the control means 116 determines the operating frequency of the compressor 121 according to the difference between the room temperature Tr and the set temperature Ts. The control signal for driving the compressor 121 is output to the compressor driving means 120.

Therefore, the compressor driving means 120 drives the compressor 121 according to the operating frequency determined by the control means 116.

When the compressor 121 is driven, the indoor fan 17 is driven into the indoor unit 1 through the suction port 3 while the indoor fan 17 is driven, and the indoor air sucked through the suction port 3 exchanges heat. Heat is exchanged by the latent heat of evaporation of the refrigerant flowing in the heat exchanger 15 while passing through the vessel 15.

The air heat-exchanged in the heat exchanger 15 is moved upward by the guide of the duct member 19 and according to the wind direction angle of the up-down wind vane 11 and the left-right wind vane 13 which are rotatably installed at the discharge port 5. Air conditioning is performed by adjusting the wind direction up and down or left and right.

In the normal operation of the air conditioner as described above, in step S8, it is determined whether the remote key of the operation operation means 102 is turned on, and when the remote key is not turned on (NO), the process returns to the step S7 and is normal. The operation below Step S7 is repeatedly performed while continuing operation.

As a result of the determination in step S8, when the remote key is turned on (YES), the key signal corresponding to the remote operation mode is input from the driving operation means 102, and the control means 116 proceeds to the air conditioner. A control signal for displaying the remote operation state of the output to the display means 130.

Therefore, in the display means 130, the remote display lamp is turned on according to the control of the control means 116 to display the remote operation state, and in step S10, the control means 116 is a place where the discharged air is far from the indoor unit 1; The driving pulse for adjusting the angle of the up-and-down wind vane 11 so as to reach (distance) is output to the up-down wind direction adjusting unit 124.

Accordingly, the up and down wind direction control unit 124 receives the driving pulse output from the control means 116 to rotate the up and down stepping motor 125, the up and down wind direction blade 11 mounted on the rotating shaft of the up and down stepping motor 125. ) Is moved upward at a predetermined angle (about 15 °), and then the driving of the up and down stepping motor 125 is stopped to fix the up and down wind vane 11.

Subsequently, in step S11, the right direction detecting unit 114 of the position detecting unit 110 detects the infrared rays generated by the human body to determine whether there is an input pulse, and inputs the right side detecting unit 114 to determine the left and right positions of the human body. If there is no pulse (NO), go to Step S12 to determine whether there is an input pulse by detecting the infrared rays generated by the human body in the left detection unit 112 of the position detecting means 110 to determine the left and right positions of the human body. do.

As a result of the discrimination in step S12, when there is an input pulse in the leftward sensing unit 112 (YES), it is determined that there is movement of the human body on the left side away from the indoor unit 1, and the flow proceeds to step S13. 116 outputs a driving pulse for swinging the left and right wind direction blades 13 to the left and right wind direction control unit 126.

Accordingly, the left and right wind direction control unit 126 receives the driving pulse output from the control means 116 and rotates the left and right stepping motor 127 to rotate the left and right wind vane 13 mounted on the rotating shaft of the left and right stepping motor 127. ) Starts moving to the left, and in step S14, the control means 116 adjusts the air volume control signal to the fan motor driving means so as to adjust the air volume when the left and right wind vanes 13 move to the left with data stored on the ROM table. 128).

Therefore, the fan motor driving means 128 controls the rotational speed of the indoor fan motor 129 according to the air volume control signal output from the control means 116, so that the left and right wind direction blades 13 move to the left, the indoor fan ( 17) Increase the air volume gradually.

At this time, in step S15, the control means 116 counts the number of output pulses to determine whether the left and right wind vane 13 has reached the left moving completion position, which means that the left and right wind vane 13 is at the left moving completion position. Since the number of pulses at the time of arrival is set in advance in the control means 116, the control means 116 counts the number of driving pulses output by the built-in counter so that the left and right wind vane 13 is moved to the left moving completion position. It can be determined whether it has reached.

As a result of the discrimination in step S15, when the left and right wind direction blades 13 do not reach the left movement completion position (NO), the control means 116 returns to the step S13. The operation of step S13 or less is repeated while outputting a drive pulse to the left and right wind direction adjustment unit 126 until the movement completion position is reached.

On the other hand, when the determination result in step S15 indicates that the left and right wind direction blades 13 have reached the left movement completion position (YES), the control means 116 moves the left and right wind direction wings 13 to the right. The driving pulse for outputting to the left and right wind direction control unit 126.

Accordingly, the left and right wind direction control unit 126 receives the driving pulse output from the control means 116 and rotates the left and right wind stepping motor 127 to start the left and right wind vane 13 to move to the right, step S17. The control means 116 outputs the air volume control signal to the fan motor driving means 128 to adjust the air volume when the left and right wind vanes 13 move to the right with the data stored on the ROM table.

Therefore, the fan motor driving means 128 controls the rotational speed of the indoor fan motor 129 according to the air volume control signal output from the control means 116 to allow the left and right wind vanes 13 to move to the right. The amount of air in (17) is gradually reduced.

At this time, in step S18, the control means 116 counts the number of output pulses to determine whether the left and right wind vane 13 has reached the right movement completion position, which means that the left and right wind vane 13 is at the right movement completion position. Since the number of pulses at the time of arrival is set in advance in the control means 116, the control means 116 counts the number of driving pulses to be output to determine whether the left and right wind vanes 13 have reached the right movement completion position. It is.

As a result of the discrimination in step S18, when the left and right wind vanes 13 do not reach the right movement completion position (NO), the control unit 116 returns to the step S16. The operation of step S16 or less is repeated while outputting a drive pulse to the left and right wind direction adjustment unit 126 until the movement completion position is reached.

On the other hand, when the determination result in step S18 indicates that the left and right wind vane 13 has reached the right movement completion position (YES), it proceeds to step S19 to determine whether the remote key is turned off, and the remote key is not turned off. In the case of NO, the process returns to the step S11 and repeats the operation of the step S11 or less.

Accordingly, the indoor air sucked through the suction port 3 is heat-exchanged by the latent heat of evaporation of the refrigerant flowing in the heat exchanger 15 while passing through the heat exchanger 15, and the air heat-exchanged in the heat exchanger 15 is ducted. Guided by (19) is moved to the upper and discharged into the room through the discharge port (5) at this time, the up and down wind vane 11 is fixed at a predetermined upward angle, the left and right wind vane 13 is swinging to the left Since the air volume gradually increases as it moves, and the air volume gradually decreases as it moves to the right side, discharge airflow is intensively supplied to the left side of the remote unit far from the indoor unit 1, thereby performing air conditioning of the far left side.

As a result of the discrimination in step S19, when the remote key is turned off (YES), the key signal corresponding to the remote operation mode stop is input from the driving operation means 102, so that the control means 116 proceeds to the far distance. The control signal for displaying the operation stop is output to the display means 130.

Therefore, in the display means 130, the remote display lamp is turned off under the control of the control means 116 to display the remote operation stop state, and in step S21, the vertical and horizontal wind vanes 11 and 13 and the indoor fan 17 Returns to the cooling or heating operation mode set value before the remote mode, and repeats the operation of step S7 or below while continuing the normal operation in step S7.

On the other hand, when the determination result in step S11 indicates that there is an input pulse in the right direction detecting unit 114 (YES), it is determined that there is movement of the human body on the right side away from the indoor unit 1, and the process proceeds to step S22. The control means 116 outputs a driving pulse for swinging the left and right wind vane 13 to the left and right wind direction control unit 126.

Accordingly, the left and right wind direction control unit 126 receives the driving pulse output from the control means 116 and rotates the left and right wind stepping motor 127 to start the left and right wind vane 13 to move to the left, and step S23. The control means 116 outputs the air volume control signal to the fan motor driving means 128 to adjust the air volume when the left and right wind vanes 13 move to the left with the data stored on the ROM table.

Therefore, the fan motor driving means 128 controls the rotational speed of the indoor fan motor 129 according to the air volume control signal output from the control means 116, so that the left and right wind direction blades 13 move to the left, the indoor fan ( 17) gradually reduce the air volume.

Accordingly, the left and right wind direction control unit 126 receives the driving pulse output from the control means 116 and rotates the left and right wind stepping motor 127 to start the right and left wind direction wing 13 to move to the right, step S26. The fan motor driving means 128 controls the rotation speed of the indoor fan motor 129 according to the air volume control signal output from the control means 116, so that the left and right wind vane 13 moves to the right, the indoor fan 17 Gradually increase the air volume.

At this time, in step S27, the control means 116 counts the number of output driving pulses and determines whether the left and right wind vane 13 has reached the right movement completion position, and the left and right wind vane 13 reaches the right movement completion position. If not (NO), the process returns to the step S25 to repeat the operation of the step S25 or less, and if the left and right wind vanes 13 have reached the right movement completion position (YES), the process goes to the step S19. Further, the operation of step S19 or less is repeated.

Accordingly, the indoor air sucked through the suction port 3 is heat-exchanged by the latent heat of evaporation of the refrigerant flowing in the heat exchanger 15 while passing through the heat exchanger 15, and the air heat-exchanged in the heat exchanger 15 is ducted. Guided by (19) is moved to the upper and discharged into the room through the discharge port (5) at this time, the up and down wind vane 11 is fixed at a predetermined upward angle, the left and right wind vane 13 is swinging to the left Since the air volume gradually decreases as it moves, and the air volume gradually increases as it moves to the right side, discharge airflow is intensively supplied to the right side of the remote unit far from the indoor unit 1 so as to perform air conditioning of the right remote region.
