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

7A and 7B are flow charts showing the air direction control operation procedure of the air conditioner according to the present invention, in which S denotes a step STEP in FIGS. 7A and 7B.

As an initial condition for explaining the operation of the present invention, it is assumed that the upper cabinet 40 in which the discharge port 9 is formed is fixed in a straight line to the lower cabinet 30.

First, when power is applied to the air conditioner, the DC power supply unit 100 converts a commercial AC voltage supplied from an AC power terminal (not shown) into predetermined DC voltages required for driving the air conditioner, thereby driving circuits and control means. Output to 104.

Therefore, in step S1, the DC voltage output from the DC power supply means 100 is inputted from the control means 104 to initialize the air conditioner, and in step S2, the indoor set temperature to be cooled by the operation operation means 102. (Ts) and the set wind amount and set wind direction are input to the control means 104.

Subsequently, at step S3, it is determined whether the operation key is turned on. If the operation key is not turned on (NO), the operation of step S3 or less is repeated while the air conditioner is kept in operation standby until the operation key is turned on. do.

As a result of the discrimination in step S3, when the operation key is turned on (YES), the control means 104 proceeds to step S4 to perform the cooling operation of the air conditioner, and the control means 104 drives the indoor fan 19. Is output to the fan motor driving means (114).

Accordingly, the fan motor driving means 114 receives the control signal output from the control means 104 according to the set air volume input by the driving operation means 102 to control the rotation speed of the indoor fan motor 115 The indoor fan 19 is driven.

When the indoor fan 19 is driven according to the set air volume, the indoor air is sucked into the main body 1 through the suction port 3, and in step S5, the temperature Tr of the indoor air sucked through the suction port 3. Is detected by the room temperature sensing means 106 and output to the control means (104).

Therefore, in step S6, it is determined whether the room temperature Tr sensed by the room temperature sensing means 106 is greater than the set temperature Ts input by the driving operation means 102, so that the room temperature Tr is determined. If the temperature is not greater than the set temperature Ts (NO), there is no need to cool the room, and the flow returns to the step S5, and the operation of the step S5 or less is repeated while continuously detecting the room temperature Tr.

As a result of the discrimination in step S6, when the room temperature Tr is larger than the set temperature Ts (YES), the room should be cooled. In step S7, the compressor is protected for a predetermined time after the indoor fan 19 is driven. If the predetermined time has not elapsed (NO), the process returns to step S4 to drive only the indoor fan 19 until the predetermined time elapses. Let's do it.

As a result of the discrimination in step S7, when the predetermined time has elapsed (YES), even if the compressor 113 is driven because the current consumption is constant, the control unit 104 in step S8 has no difficulty. The operation frequency of the compressor 113 is determined according to the difference between the room temperature Tr and the set temperature Ts, and a control signal for driving the compressor 113 is output to the compressor driving means 112.

Accordingly, the compressor driving means 112 drives the compressor 113 according to the operating frequency determined by the control means 104.

When the compressor 113 is driven, the indoor fan 19 is driven in step S9 while the indoor air is sucked into the lower cabinet 30 through the suction port 3, and the indoor air sucked through the suction port 3. The foreign matter such as floating dust is removed while passing through the filter member 7, and the indoor air from which the foreign matter such as dust is removed by the filter member 7 passes through the heat exchanger 17. Heat exchanged with cold air by latent heat of evaporation of the flowing refrigerant.

The air heat-exchanged in the heat exchanger 17 is moved upward by the guidance of the duct member 21, and the air passing through the duct member 21 passes through the flow path portion 54a of the connecting member 54. As it rises up, it passes through the through hole 56a of the rotating plate 56 and the through hole 40a of the upper cabinet 40 and flows into the upper cabinet 40.

As described above, the heat-exchanged air introduced into the upper cabinet 40 is rotated according to the wind direction up and down control plate 11 and the wind direction left and right control plate 13 installed to be rotated to the discharge port 9 of the upper cabinet 40. Perform normal operation to cool the room while the wind direction is adjusted up and down or left and right.

In the normal operation of the air conditioner as described above, in step S10, it is determined whether the rotary key of the operation operation means 102 is turned on, and when the rotary key is not turned on (NO), the operation returns to the step S9 and is operated normally. Continue to run

As a result of the determination in step S10, when the rotation key is turned on (YES), the control means 104 advances the control signal 104 to the left side of the fixed upper cabinet 40, and the motor drive means 108. Output to

Accordingly, in the motor driving means 108, the first gear 53 coupled to the motor shaft member 52 rotates forward by driving the motor 51 under the control of the control means 104, and the first gear is rotated. As the second gear 54 geared with the one side of the 53 is reversely rotated, the connecting member 54 inserted into the second gear 54 rotates clockwise.

Accordingly, the upper plate 40 coupled by the boss 56b protruding to the edge of the rotary plate 56 is rotated in conjunction with the rotary plate 56 coupled to the connecting member 54 to the left. Rotate

When the upper cabinet 40 is turned left, in step S12 the contact portion 59a provided on the lower left side of the rotating plate 56 is in contact with the second position sensor 59 provided on the upper left side of the lower cabinet 30 so that the upper cabinet The left turn position of the 40 is sensed, and the control means 104 receives the signal sensed by the second position sensor 59 to determine whether the upper cabinet 40 is completely turned left.

As a result of the discrimination in step S12, when the upper cabinet 40 does not turn left completely (NO), the motor 51 is continuously driven until the upper cabinet 40 turns completely left by returning to step S11. If the upper cabinet 40 is completely turned left (YES), the control means 104 outputs a control signal to the motor driving means 108 for turning the left upper cabinet 40 to the right. do.

Therefore, in the motor driving means 108, by driving the motor 51 under the control of the control means 104, the first gear 53 coupled to the motor shaft member 52 is reversed, the first As one side of the gear 53 and the second gear 54 engaged with the gear are rotated forward, the connecting member 54 inserted into the second gear 54 rotates counterclockwise.

Accordingly, the upper plate 40 coupled by the boss 56b protruding to the edge of the rotary plate 56 is rotated in conjunction with the rotary plate 56 coupled to the connecting member 54 to the right. Rotate

When the upper cabinet 40 is rotated to the right, in step S14, the contact portion 60a provided on the lower right side of the rotating plate 56 contacts the third position sensor 60 provided on the upper right side of the lower cabinet 30 so that the upper cabinet ( The right turn position of 40 is sensed, and the control means 104 receives the signal sensed by the third position sensor 60 to determine whether the upper cabinet 40 is completely turned right.

As a result of the discrimination in step S14, when the upper cabinet 40 does not turn completely right (NO), the motor 51 is continuously driven until the upper cabinet 40 turns completely right after returning to step S13. If the upper cabinet 40 is completely turned right (YES), the flow advances to step S15 to determine whether the operation key is turned off. If the operation key is not turned off (NO), the flow returns to step S11. The motor 51 is rotated forward and backward to repeat the operation of step S11 or less while reciprocating the upper cabinet 40 to the left and right.

Therefore, the indoor air sucked into the lower cabinet 30 through the suction port 3 in accordance with the operation of the indoor fan 19 passes through the heat exchanger 17 and is cooled by the latent heat of evaporation of the refrigerant flowing in the heat exchanger 17. Heat exchanged with air, the air heat exchanged in the heat exchanger 17 is moved to the upper side guided by the duct member 21, the air passing through the duct member 21 is the flow path of the connection member 54 is rotated It rises along the part 54a and passes through the through-hole 56a of the rotating plate 56 and the through-hole 41 of the upper cabinet 40, and flows into the upper cabinet 40 inside.

As described above, the heat-exchanged air introduced into the upper cabinet 40 is rotated according to the wind direction up and down control plate 11 and the wind direction left and right control plate 13 installed to be rotated to the discharge port 9 of the upper cabinet 40. The air discharged through the discharge port 9 is not limited to the front side of the main body 1 by controlling the discharge wind direction up and down or left and right and increasing the angle of the wind direction of the discharged air by the left and right rotation of the upper cabinet 40. As it is discharged in various directions without air conditioning, it is possible to eliminate the air conditioning restriction according to the excretion position of the air conditioner type air conditioner.

As a result of the discrimination in step S15, when the operation key is turned off (YES), the process proceeds to step S16 and the contact portion provided on the front side surface of the rotating plate 56 which rotates the upper cabinet 40 in accordance with the drive of the motor 51. 58a is in contact with the first position sensor 58 installed on the upper front side of the lower cabinet 30 to detect the home position of the upper cabinet 40 is fixed in a straight line with respect to the lower cabinet 30, the control means ( In 104, the signal sensed by the first position sensor 58 is input to determine whether the upper cabinet 40 is completely fixed at the original position.

As a result of the discrimination in step S16, when the upper cabinet 40 is not in its original position (NO), the motor 51 continues to be driven until the upper cabinet 40 is fixed to the original position by returning to the step S16. When the upper cabinet 40 is in the original position (YES), the motor driving means 108 stops the driving of the motor 51 under the control of the control means 104 and moves to the step S17. Complete the home position operation of.

Subsequently, in step S18, the control means 104 ends the operation while maintaining the air conditioner in the operation standby state until the operation key of the operation operation means 102 is turned on again.
