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

4A to 4C are flowcharts showing the operation flow of the airflow control of the air conditioner according to the present invention. In FIGS. 4A to 4C, 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 inputted from the control means 116 to initialize the air conditioner. In step S2, the control means 116 uses the wind direction up and down control plate 9 as an operation origin. The control signal for driving the first wind direction control motor 125 is output to the first wind direction motor driver 124 to move to the closed state.

Accordingly, the first wind direction motor driver 124 receives the control signal output from the control means 116 and drives the first wind direction control motor 125 at an angular speed of 22.5 ° / sec in a clockwise direction to adjust the wind direction up and down control panel. Close (9).

Subsequently, in step S3, the control means 116 transmits a control signal to the second wind direction motor driver 126 to drive the second wind direction control motor 127 to move the wind direction left and right control plate 11 to the closed state, which is the operation origin. Output

Accordingly, the second wind direction motor driver 126 receives the control signal output from the control means 116 and drives the second wind direction control motor 127 at an angular speed of 22.5 ° / SEC in the clockwise direction to adjust the wind direction left and right control plate ( 11) Close it.

At this time, in step S4, the control means 116 counters the driving time of the first and second wind direction control motors 125 and 127 to determine whether a predetermined time (about 7 seconds) has elapsed, and when the predetermined time has not elapsed. In the case of NO, it is determined that the wind direction up and down control plate 9 and the wind direction left and right control plate 11 are not completely closed, and the flow returns to step S2 to repeat the operation of step S2 or less until a predetermined time elapses.

As a result of the determination in step S4, when a predetermined time has elapsed (YES), it is determined that the wind direction up and down control plate 9 and the wind direction left and right control plate 11 are completely closed, and the flow proceeds to step S5 to determine the first and second wind directions. The motor driving units 124 and 126 stop driving of the first and second wind direction regulating motors 125 and 127 under the control of the control means 116 to complete the closing operation of the wind direction up and down control plate 9 and the wind direction left and right control plate 11. This state is used as a starting point for operation.

On the other hand, the initialization routine from step S2 to step S5 is also performed at the time of driving off, which means that the wind direction up and down control plate 9 and the wind direction left and right control plate 11 are positioned by an arbitrary external operation when the power is turned on or when the operation is off. If it is changed to precise position control is difficult to perform the initialization routine to completely close the wind direction up and down control panel 9 and the wind direction left and right control panel (11).

Subsequently, in step S6, the set temperature Ts, the set air volume, and the set wind direction of the room to be cooled or heated by the operating operation means 102 are input to the control means 116, and in step S7, the operation / stop key (hereinafter referred to as " If the operation key is not turned on (NO), the operation of step S7 or less is repeated while the air conditioner is kept in operation standby until the operation key is turned on. .

As a result of the discrimination in step S7, when the operation key is turned on (YES), an operation command and an operation signal are input from the operation operation means 102 to the control means 116, so that the operation of cooling or heating can be performed in step S8. Further, the control means 116 outputs a control signal for driving the indoor fan motor 21 to the fan motor driving means 128.

Accordingly, the fan motor drive means 128 receives the control signal output from the control means 116 according to the set air volume inputted by the driving operation means 102 (speed) of the indoor fan motor 21. To drive the indoor fan (23).

When the indoor fan 23 is always driven according to the set air volume, the indoor air is sucked into the main body 1 through the suction port 3, and at this time, the temperature Tr of the indoor air sucked through the suction port 3 is measured as the room temperature. The sensing means 118 detects and outputs the control means 116.

Subsequently, in step S9, the control means 116 adjusts the wind direction angles of the wind direction up and down control plate 9 and the wind direction left and right control plate 11 according to the set wind direction inputted by the driving operation means 102. A control signal for driving the wind direction control motors 125 and 127 is output to the first and second wind direction motor drivers 124 and 126.

Accordingly, the first and second wind direction motor drivers 124 and 126 receive the control signals output from the control means 116 and drive the first and second wind direction control motors 125 and 127 to wind up and down the regulating plate 9 and the wind direction. The wind direction angle of the left and right adjustment plate 11 is adjusted according to the wind direction set by the user.

Subsequently, in step S10, 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 S10, when it is not the driving condition of the compressor 121 (NO), the process returns to the step S8 and repeatedly performs the operation of step S8 or below 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 23 is driven while the indoor fan 23 is driven, and the indoor air is sucked into the main body 1 through the suction port 3 and suspended in the indoor air sucked through the suction port 3. Foreign matter such as dust is removed while passing through the filter member 17, and the indoor air from which foreign matter such as dust is removed by the filter member 17 flows into the heat exchanger 19 while passing through the heat exchanger 19. Heat exchanged by latent heat of evaporation of the refrigerant.

The air heat-exchanged in the heat exchanger 19 is moved to the upper side by the guide of the duct member 25 and according to the wind direction angle of the wind direction up and down control plate 9 and the wind direction left and right control plate 11 installed so as to be rotatable in the discharge port 7. 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, the step S13 detects and inputs infrared rays generated in the human body by the middle distance detection unit 108 of the perspective sensing means 104 to determine whether the human body is within a center distance within 4 m. If it is determined that there is a pulse, and if there is no input pulse in the intermediate distance detecting unit 108 (NO), the process moves to step S14 to determine the left and right positions of the human body. ) Detects the infrared rays generated by the human body to determine whether there is an input pulse.

As a result of the discrimination in step S14, when there is an input pulse in the leftward sensing unit 112 (YES), the process proceeds to step S15 and the rightward sensing unit 114 of the left and right sensing means 110 determines the left and right positions of the human body. ) Detects the infrared rays generated by the human body to determine whether there is an input pulse.

As a result of the discrimination in step S15, when 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 left and right sides away from the main body 1, and the process proceeds to step S16. Further, the control means 116 sets the operation mode of the air conditioner to the A mode, and when the right direction detecting unit 114 does not have an input pulse (NO), the left side far away from the main body 1 In step S17, the control means 116 sets the operation mode of the air conditioner to the B mode.

On the other hand, when the determination result in step S14 indicates that there is no input pulse in the leftward detection unit 112 (NO), the flow advances to step S18 to determine whether there is an input pulse in the rightward detection unit 114, and to the rightward direction. If there is an input pulse in the sensing unit 114 (YES), it is determined that there is movement of the human body only on the right side away from the main body 1, and the flow proceeds to step S19, whereby the control means 116 operates the air conditioner. Set the mode to C mode.

As a result of the discrimination in step S18, when there is no input pulse in the right direction detecting unit 114 (NO), it is determined that there is no movement of the human body on the left and right sides away from the main body 1, and the process proceeds to step S20. Further, the control means 116 sets the operation mode of the air conditioner to the D mode.

On the other hand, when the determination result in step S13 indicates that there is an input pulse in the intermediate distance detection unit 108 (YES), the process proceeds to step S20 and performs operations below step S20.

Subsequently, in step S21, it is determined whether the operation mode of the air conditioner is the D mode, and if it is not the D mode (NO), the control means 116 displays the remote operation state of the air conditioner. The control signal for the output to the display means 130.

Therefore, in the display means 130, the remote display lamp is turned on to display the remote operation state under the control of the control means 116. In step S23, the control means 116 has the air discharged through the discharge port 7 in the main body. A control signal for driving the indoor fan motor 21 is output to the fan motor driving means 128 so as to reach a far distance (distant) from (1).

Accordingly, the fan motor driving means 128 receives the control signal output from the control means 116 to drive the rotational speed of the indoor fan motor 21 at the turbo wind amount (about 670 RPM), and control in step S24. The means 116 outputs, to the first wind direction motor driver 124, a control signal for adjusting the angle of the wind direction up and down control plate 9 so that the discharged air reaches a distance.

Subsequently, in step S25, it is determined whether the operation mode of the air conditioner is A mode. If it is not in A mode (NO), the flow advances to step S26 to determine whether the operation mode of the air conditioner is B mode.

As a result of the discrimination in step S26, if it is not B mode (NO), it is determined that the operation mode is C mode, and the flow advances to step S27, whereby the control means 116 adjusts the wind direction left and right control plates 11 to reach the far distance.

As shown, after the movement to the right predetermined angle (about 15 °), the driving of the second wind direction control motor 127 is stopped.

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 19 while passing through the heat exchanger 19, and the air heat-exchanged in the heat exchanger 19 is ducted. The discharge air flow is moved to the upper side by the guide of the 25 and the discharge air flow is fixed by the fixed upward angle of the wind direction up and down control plate 9 installed in the discharge port 7 and the fixed right angle of the wind direction left and right control plate 11. The air volume of the discharged air increases as the turbo fan of the indoor fan motor 21 is driven while reaching the right side of a distant place, and the air conditioner of the far right is returned to the step S13 to repeat the operation of step S13 or less.

Perform.

In addition, when the determination result in step S25 is in the A mode (YES), the process proceeds to step S29, where the second wind direction motor driver 126 receives the control signal output from the control means 116 to adjust the second wind direction. After driving the motor 127 to move the angle of the wind direction left and right control plate 11 to the center constant angle as shown in FIG. 6 (b), the driving of the second wind direction adjustment motor 127 is stopped. .

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 19 while passing through the heat exchanger 19, and the air heat-exchanged in the heat exchanger 19 is ducted. The discharge air flow is moved to the upper side by the guide of the 25 and the discharge air flow is fixed in accordance with the fixed constant angle upward of the wind direction up and down control plate 9 installed in the discharge port 7, and fixed to the center constant angle of the wind direction left and right control plate 11.
