A microcomputer that controls the overall operation of the air conditioner in accordance with a stop signal, wherein the control means 116 is provided by the distance sensing means 104 such that the discharge air is diffused throughout the room in accordance with the on-key operation of the wide key. According to the sensed proximity distance of the human body and the left and right positions of the human body sensed by the position detecting means 110 controls the wind direction angle of the upper and lower and left and right wind vanes (11, 13) and the air volume of the indoor fan (17).

The indoor temperature detecting means 118 detects the temperature Tr of the indoor air sucked through the intake port 3 so as to detect the indoor temperature of the location where the indoor unit 1 is installed, and the compressor driving means 120 operates the operation. The compressor receives a control signal output from the control means 116 according to the difference between the temperature Ts set by the user 102 and the room temperature Tr sensed by the room temperature sensing means 118. Drive control 121 is performed.

In addition, the wind direction control means 122 is the proximity distance of the human body sensed by the distance sensing means 104 so that the air discharged through the discharge port 5 is spread throughout the room in accordance with the ON operation of the wide key According to the left and right positions of the human body sensed by the position detecting means 110 to adjust the direction of the discharge air up and down and left and right, the wind direction adjusting means 122 receives the pulse signal output from the control means 116 Up and down wind direction control unit 124 for driving the up and down wind stepping motor 125 to move the up and down wind vane 11 and the pulse signal output from the control means 116 to receive the left and right wind vane 13 to move.

The indoor fan 17 is driven by controlling the rotation speed of the indoor fan motor 129 by receiving a control signal output from the control means 116 to blow the air into the room.

In addition, in the drawing, the display means 130, the operation selection mode (automatic, cooling, dehumidification, blowing, heating, etc.) and temperature inputted by the operation operation means 102 under the control of the control means 116 and the temperature and In addition to displaying the time, the wide display lamp for displaying the wide operation state of the entire room is turned on / off.

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 mode selection control operation procedure of the wide mode to which the present invention is applied. 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 control means 116 transmits a control signal for driving the indoor fan motor 129 to the fan motor driving 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.

Therefore, the up and down and left and right wind direction control unit 124, 126 receives the control signal output from the control means 116 to drive the up and down and left and right wind direction blades 11 and left and right wind direction wings by driving the stepping motor (125, 127) Adjust the wind direction angle of (13) 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 Tr) is smaller than the set temperature Ts 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 wide key of the operation operation means 102 is turned on, and when the wide 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 discrimination in step S8, when the wide key is turned on (YES), the key signal corresponding to the wide operation mode is input from the driving operation means 102, so the control means 116 proceeds to the air conditioner. The control signal for displaying the wide operation state of the output to the display means (130).

Accordingly, the display means 130 displays a wide operation state by turning on the wide display lamp under the control of the control means 116, and in the stem S10, the position detecting means 110 determines whether the human body is within a close distance within 2 m. The near field detection unit 106 detects infrared rays generated by the human body to determine whether there is an input pulse.

As a result of the determination in step S10, when there is no input pulse in the near field sensing unit 106 (NO), the process proceeds to step S11 to determine whether the human body is within a center distance within 4 m. The mid-range detection unit 108 detects infrared rays generated by the human body to determine whether there is an input pulse.

As a result of the discrimination in step S11, when there is no input pulse in the intermediate distance detecting unit 108 (NO), the control unit 114 moves to the step S12 to determine the left and right positions of the human body. Infrared rays generated by the human body are detected to determine whether there is an input pulse, and when there is an input pulse in the right-side detection unit 114 (YES), the human body moves to the right away from the indoor unit 1. It is determined that it is, and enters the right remote mode.

As a result of the discrimination in step S12, when there is no input pulse in the right direction detecting unit 114 (NO), the process moves to step S13 to determine the left and right positions of the human body. Infrared rays generated by the human body are detected to determine whether there is an input pulse, and when there is an input pulse in the leftward sensing unit 112 (YES), the human body moves on the left side away from the indoor unit 1. It is determined that the system is present and enters the left principle mode.

As a result of the determination in step S13, when there is no input pulse in the leftward sensing unit 112 (NO), the flow advances to step S14 to determine whether the wide key is turned off, and when the wide key is not turned off (NO day). If), the process returns to step S10 and repeats the operation of step S10 or less.

As a result of the discrimination in step S14, when the wide key is turned off (YES), the key signal corresponding to the wide operation mode stop is input from the driving operation means 102, so the control means 116 proceeds to step S15. The control signal for displaying the operation stop is output to the display means 130.

Therefore, the display means 130 turns off the wide display lamp to display the wide operation stop state under the control of the control means 116, and returns to the step S7 to return the upper and lower and left and right wind vanes 11 and 13 and the indoor fan. Numeral 17 repeats the operation of step S7 or below while continuing normal operation to the cooling or heating operation mode set value before the wide mode.

On the other hand, when the determination result in the step S10, if there is an input pulse (in the case of YES) in the near-field detection unit 106, the flow of the left detection unit of the position detection means 110 to determine the left and right positions of the human body to go to step S16 ( 112 detects the infrared rays generated by the human body to determine whether there is an input pulse, the movement of the human body to the left near the indoor unit 1, if there is an input pulse (YES) in the left-side detection unit 112 It determines that it is, and enters the near-left mode.

As a result of the discrimination in step S16, when there is no input pulse in the leftward sensing unit 112 (NO), it is determined that there is movement of the human body on the right side near the indoor unit 1, and enters the right near-field mode.

Next, the discharge airflow control operation in the left far mode, the right far mode, the left near mode and the right near mode in accordance with the operation mode selected above will be described.

First, the control operation of the left far mode will be described with reference to FIGS. 5A and 5B.

5A and 5B are flowcharts showing an operation procedure of the discharge airflow control in the left far mode applied to the present invention.

When the air conditioner enters the left remote mode according to the proximity distance and the left and right positions of the human body, in step S20, the control means 116 outputs a driving pulse for moving the left and right wind vanes 13 to the left and right wind direction controller 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 S21 the control means 116 adjusts the air volume control signal to the data stored on the ROM table when the left and right wind direction blades 13 move to the left. 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 S22, 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 S22, when the left and right wind vanes 13 do not reach the left movement completion position (NO), the flow returns to step S20 to repeat the operation of step S20 and below.

On the other hand, when the determination result in step S22 indicates that the left and right wind direction blades 13 have reached the left movement completion position (YES), the control means 116 moves the up and down wind direction blades 11 to step S23. The driving pulse for the output to the up and down wind direction control unit 124.

Accordingly, the up and down wind direction control unit 124 receives the driving pulse output from the control means 116 and rotates the up and down stepping motor 125 to start the up and down wind vane 11 to move upward, and in step S24 The control means 116 outputs the air volume control signal to the fan motor driving means 128 so as to adjust the air volume when the up-and-down wind vane 11 moves upward 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 up-and-down wind vane 11 moves upward, and the indoor fan 17 ) Increase the air volume gradually.

At this time, in step S25, the control means 116 counts the number of output pulses to determine whether the up-down wind vane 11 has reached the ascending completion position, and the up-down wind vane 11 has not reached the ascending completion position. In the case of NO, the process returns to the step S23 to repeat the operation of the step S23 or less.

As a result of the discrimination in step S25, when the up-and-down wind vane 11 reaches the ascending completion position (YES), the flow advances to step S26, and the control means 116 moves the right and left wind vane 13 to the right. The driving pulse is output 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 S27. 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, so that the left and right wind direction wings 13 move to the right, the indoor fan ( 17) gradually reduce the air volume.

At this time, in step S28, the control means 116 counts the number of driving pulses to be output 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 flow returns to step S26 to repeat the operation of step S26 or less.

On the other hand, when the determination result in step S28 indicates that the left and right wind direction blades 13 have reached the right movement completion position (YES), the control means 116 moves the up and down wind direction blades 11 to step S29. The driving pulse for the output to the up and down wind direction control unit 124.

Accordingly, the up and down wind direction control unit 124 receives the driving pulse output from the control means 116 and rotates the up and down stepping motor 125 to start the up and down wind vane 11 to move downward, and step S30. The control means 116 outputs the air volume control signal to the fan motor driving means 128 to adjust the air volume when the up-and-down wind vane 11 moves downward to 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 up and down wind vane 11 moves downwards. 17) gradually reduce the air volume.
