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 surround display lamp for displaying the surround operation status 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 surround mode applied to the present invention, in which S denotes a step (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. A 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 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 surround key of the operation operation means 102 is turned on, and if the surround 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 surround key is turned on (YES), the key signal corresponding to the surround operation mode is input from the driving operation means 102, so the control means 116 proceeds to the air conditioner. A control signal for displaying the surround operation state of the output to the display means (130).

Accordingly, the display means 130 displays the surround operation state by turning on the surround display lamp under the control of the control means 116, and in step S10, the position sensing means 110 to determine whether the human body is within a close distance of 2 m or less. 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, and when the mid-range detection unit 108 has an input pulse (YES), it is slightly away from the indoor unit 1. Judging that the movement of the human body in the center of the room enters the central mode.

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 far left mode.

As a result of the discrimination in step S13, if there is no input pulse in the leftward sensing unit 112 (NO), the flow advances to step S14 to determine whether the surround key is off, and if the surround key is not 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 surround key is turned off (YES), the key signal corresponding to the stop of the surround operation mode is input from the driving operation means 102, and the control means 116 proceeds to the surround. The control signal for displaying the operation stop is output to the display means 130.

Accordingly, the display means 130 displays the surround operation stop state by turning off the surround display lamp according to the control of the control means 116, and returns to the step S7 to move up and down and left and right wind vanes 11 and 13 and the indoor fan. Reference numeral 17 repeats the operations below Step S7 while continuing normal operation to the cooling or heating operation mode setting values before the surround 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, the right near mode and the center mode will be described according to the operation mode selected above.

First, the control operation of the left far mode will be described with reference to FIG. 5.

Fig. 5 is a flowchart showing the 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, the control means 116 at step S20 controls the driving pulse for moving the up and down and left and right wind vanes 11 and 13. Output to (124,126).

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. ) Starts to move upward, 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 the left and right mounted on the rotating shaft of the left and right stepping motor 127 The wind vane 13 starts to move to the left.

When the up-and-down wind vane 11 is moved upward and the left and right wind vane 13 is moved to the left side, in step S21, the control means 116 moves the upper and lower wind vanes 11 upwards from half of the whole, and the left and right wind vanes ( 13) outputs a driving pulse for swinging the left half of the whole to the upper and lower and left and right wind direction control unit (124,126).

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 wind stepping motor 125, the up and down wind vane 11 swings on the upper half of the whole. 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 direction blades 13 by rotating the left and right stepping motor 127.

At this time, in step S22, the control means 116 adjusts the air volume control signal to adjust the air volume when the upper, lower, left and right wind vanes 11 and 13 swing from the upper half or the left side of the whole to the data stored on the ROM table. Output to fan motor driving means 128.

Accordingly, 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 up and down and left and right wind vanes 11 and 13 are outward (up and down). The wind vane is at the top and bottom ends of the top half, and the left and right wind vane is at the left and right ends at the left half of the whole half. Is gradually increased to the air volume of the indoor fan 17 as it moves to the middle portion on the left half).

Subsequently, in step S23, 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 up, down, left and right wind vanes 11 and 13 stop. (I.e., up and down wind vane is halfway up halfway, left and right wind vane is halfway left half) from the outside (up and down wind vane up and down ends at half full top, left and right wind vane Is gradually reduced in the air volume of the indoor fan 17 as it moves to the left and right ends of the entire 1/2).

At this time, in step S24, it is determined whether the surround key is turned off. If the surround key is not turned off (NO), the process returns to the step S21 and repeats the operation of step S21 and below.

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. Under the guidance of (19) it is moved upward and discharged to the room through the discharge port (5), at this time the upper and lower wind direction blades 11 of the upper half of the left and right wind direction (13) is half of the whole As the upper and lower and left and right wind vanes (11, 13) move from the outside to the inside, the air volume gradually increases, and as the outside moves out, the air flow gradually decreases. As shown in the figure, a strong wind discharge air flows around the human body to supply air to the far left.

As a result of the discrimination in step S24, when the surround key is turned off (YES), the key signal corresponding to the stop of the surround operation mode is input from the driving operation means 102, and the flow proceeds to step S25 to the up and down and left and right wind vanes 11 13, the indoor fan 17 returns to the cooling or heating operation mode setting value before the surround mode, and repeats the operation of step S7 or below while continuing the normal operation in step S7.

Next, the control operation of the right far mode will be described with reference to FIG.

Fig. 6 is a flowchart showing the operation procedure of the discharge airflow control in the right far mode applied to the present invention.

When the air conditioner enters the right remote mode according to the proximity distance and the left and right positions of the human body, in step S30 the control means 116 is to move the driving pulse for moving the up and down and left and right wind vanes (11, 13) up and down and left and right wind direction control unit Output to (124,126).

Accordingly, the up and down wind direction control unit 124 receives the driving pulse output from the control means 116 by rotating the up and down stepping motor 125, the up and down wind direction blade 11 starts to move upwards, the left and right wind direction control The unit 126 receives the driving pulse output from the control means 116 and rotates the left and right stepping motor 127 to start the left and right wind vane 13 to move to the right.

When the up-and-down wind vane 11 is moved upward and the left and right wind vane 13 is moved to the right, in step S31, the control means 116 moves the upper and lower wind vanes 11 at the upper half of the whole, and the left and right wind vanes ( 13) outputs a driving pulse for swinging the right half of the whole to the upper and lower and left and right wind direction control unit (124,126).

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 wind stepping motor 125, the up and down wind vane 11 swings on the upper half of the whole. 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 so that the left and right wind vane 13 swings on the 1/2 right side.

At this time, in step S32, the control means 116 adjusts the air volume control signal to adjust the air volume when the upper and lower and left and right wind vanes 11 and 13 swing from the upper half or the right side of the whole with the data stored on the ROM table.

The wind vane is at the top and bottom ends of the top half, and the left and right wind vane is at the left and right ends at the right half of the entire half. Is gradually increased to the air volume of the indoor fan 17 as it moves to the middle portion at the right half.

(I.e., up and down wind vane is halfway up halfway, left and right wind vane halfway up halfway) from outside (up and down wind vane up and down ends at half full top, left and right wind vane Is gradually reduced in the air volume of the indoor fan 17 as it moves to the left and right ends at the right half.

At this time, in step S34, it is determined whether the surround key is turned off. If the surround key is not turned off (NO), the flow returns to step S31 to repeat the operation of step S31 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. Under the guidance of (19) it is moved upward and discharged to the room through the discharge port (5), at this time the upper and lower wind direction blades 11 of the upper half of the left and right wind direction (13) is half of the whole As the upper and lower and left and right wind vanes 11 and 13 move from the outside to the inside, the air volume gradually increases, and as the outside moves outside, the air flow gradually decreases, so the eddy curve is located on the right side of the remote unit far from the indoor unit 1. As shown in the figure, a strong wind discharge air flows around the human body and is supplied to perform air conditioning at the far right.

As a result of the discrimination in step S34, when the surround key is turned off (YES), the key signal corresponding to the stop of the surround operation mode is input from the driving operation means 102, and the flow proceeds to step S35 to the up and down and left and right wind vanes 11 13, the indoor fan 17 returns to the cooling or heating operation mode setting value before the surround mode, and repeats the operation of step S7 or below while continuing the normal operation in step S7.

When the up-and-down wind vane 11 is moved downward and the left and right wind vane 13 is moved to the left side, in step S41, the control means 116 moves the up and down wind vane 11 down from 1/2 of the whole, the left and right wind vane. The driving pulse for swinging (13) from the left half of the whole is output to the up and down and left and right wind direction control units 124 and 126.

At this time, in step S44, it is determined whether the surround key is off, and when the surround key is not off (NO), the process returns to the step S41 and repeats the operation of step S41 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. Under the guidance of (19) it is moved to the upper and discharged to the room through the discharge port (5) at this time, the upper and lower wind direction blades 11 are the lower half of the whole right and left wind direction wings (13) 1/2 of the whole As the upper and lower and left and right wind vanes (11, 13) move from the outside to the inside, the air volume gradually increases, and as the outside moves inward, the air volume gradually decreases, so a eddy curve is drawn on the left side of the short distance close to the indoor unit (1). As the wind flows around the human body, a strong wind discharge stream is supplied to perform air conditioning in the near left.

As a result of the discrimination in step S44, when the surround key is turned off (YES), the key signal corresponding to the stop of the surround operation mode is input from the driving operation means 102. 13, the indoor fan 17 returns to the cooling or heating operation mode setting value before the surround mode, and repeats the operation of step S7 or below while continuing the normal operation in step S7.

When the up-and-down wind vane 11 moves downward and the left and right wind vane 13 moves to the right, in step S51, the control means 116 moves the upper and lower wind vanes 11 down from the lower half of the whole, the left and right wind vanes. The driving pulse for swinging (13) from the right half of the whole is output to the up and down and left and right wind direction control units 124 and 126.

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, the up and down wind direction blades 11 swing below half of the whole. 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 so that the left and right wind vane 13 swings on the 1/2 right side.

At this time, in step S54, it is determined whether the surround key is turned off. If the surround key is not turned off (NO), the process returns to the step S51 and the operation of step S51 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. Under the guidance of (19) it is moved to the upper and discharged to the room through the discharge port (5) at this time, the upper and lower wind direction blades 11 are the lower half of the whole right and left wind direction wings (13) 1/2 of the whole As the upper and lower and left and right wind vanes (11, 13) move from the outside to the inside, the air volume gradually increases, and the air flow gradually decreases as the outside moves inward, so a eddy curve is drawn on the right side of the short distance close to the indoor unit (1).
