Turning the wind direction forward and reverse motors on, and driving the wind direction forward and reverse motors to 65 ° (reverse forward) (S17), and determining whether the weak switch input is input at step S11 (S18); Wind direction tablet at the same time with the step (S19) to turn on the blower fan in the step (S18), A step S20 of driving the motor up to 70 ° (forward rotation), a step S21 of checking whether the key input switch is turned off in step S11, and a blower fan if the step S21 is determined And step S23 of returning the wind direction, forward and reverse motors to their original positions (reverse rotation) simultaneously with the step of driving off the engine (S22).

Referring to the operation and effects of the present invention configured as described above in detail.

First, in the present invention, the blowing air is provided at the output terminals P4, P5, P6, and P7 according to the input of the strong, medium, and weak switches SW1, SW2, and SW23 provided in the key input unit 1. The wind direction and inverse motor 50 controlling the fan 30 and the wind direction variable stage A at a predetermined angle is simultaneously controlled. This is a uniform method in which the conventional wind direction variable stage A control is manually operated. There is an effect to exclude.

Specifically, the initial power is applied to the circuit and the initialization state proceeds (S10), and at the same time, the microcomputer 2 waits for input of the strong, medium, and weak switches SW1, SW2, and SW3 (S11). In this case, when the user wants to acquire the strong wind (S12), when the user operates the strong switch SW1, the low level signal is input to the input terminal P1 of the microcomputer 2, and the microcomputer 2 inputs the strong switch SW1. It is determined that this is made, and a high level signal is applied to the output terminal P4.

This is because the high level signal turns on the transistor Q1 through the resistor R4 so that the power source AC is applied to the blowing fan 30 as it is, so that the blowing fan 30 discharges the strong wind forward as it is (S13). ). At the same time, the microcomputer 2 applies a high level to the output terminal P7 so that the strong blowing fan 30 can be effectively discharged, and the transistor Q4 is turned on so that the relay RY1 is energized. 50 is rotated forward to move the wind direction variable stage (A) at a predetermined angle (S14). That is, when the wind direction tablet and the reverse motor 50 installed in the support 12 are rotated forward, the nut 122 also rotates and rises at the same time according to the rotation of the bolt 121 that rotates in conjunction with it. The variable blade 125 and the plurality of ribs 124 are moved in accordance with the movement of the 123. At this time, since the angle is limited to only 60 ° in the present invention, it is preferable that the wind direction tablet and the reverse motor 50 operate only within that time by setting a different time in advance.

If the user wants to obtain only the above-mentioned wind, if the user operates the heavy switch SW2 (S15), the low level signal is inputted to the input terminal P2 of the microphone 2 and the heavy switch is input by the microcomputer 2. It is determined that the input of the SW2 is made, and a high level signal is applied to the output terminal P4. That is, the high level signal through the resistor R6 turns on the transistor Q2, but the power supply AC through the transistor Q2 is reduced to a predetermined value due to the voltage drop of the resistor R8. By being applied to the blower fan 30, the blower fan 30 discharges the middle wind forward (S16). At the same time, the microcomputer 2 applies a high level to the output terminal P7 in order to efficiently discharge the intermediate wind, so that the transistor Q4 is turned on and the relay RY1 is energized. 50, the forward direction variable stage (A) is moved by a predetermined angle (S17). That is, when the wind direction tablet and the reverse motor 50 installed in the support 12 are rotated forward, the nut 122 also rotates and rises at the same time according to the rotation of the bolt 121 that rotates in conjunction with it. The variable blade 125 and the plurality of ribs 124 are moved in accordance with the movement of the 123. At this time, since the angle is limited to only 65 ° in the present invention, the time according to the angle shift is set in advance so that the wind direction tablet and the reverse motor 50 operate only within the time.

On the other hand, when the user wants to acquire a weak wind (S18) when the user operates the weak switch (SW3) the low level signal is input to the input terminal (P3) of the microcomputer 2, the microcomputer 2 of the weak switch (SW3) It is determined that the input is made, and a high level signal is applied to the output terminal P6. That is, the high level signal through the resistor R10 turns on the transistor Q3, but the voltage at which the power supply AC through the transistor Q3 drops to a predetermined value due to the voltage drop of the resistors R8 to R9 is reduced. By being applied to the blower fan 30, the blower fan 30 discharges the lowest wind forward (S19). At the same time, the microcomputer 2 applies a high level to the output terminal P7 in order to discharge the wind efficiently and effectively, so that the transistor Q4 is turned on and the relay RY1 is energized. The wind direction variable stage (A) is moved to a predetermined angle by the forward rotation (S20). That is, when the wind direction reverse motor 50 installed in the support 12 is rotated forward, the nut portion 122 also rotates at the same time in accordance with the rotation of the bolt portion 121 to rotate in conjunction with it, and thus the folding table The variable blade 125 and the plurality of ribs 124 are moved in accordance with the movement of the 123. At this time, since the angle is limited to only 70 ° in the present invention, the time according to the angle shift is set in advance so that the wind direction tablet and the reverse motor 50 operate only within the time.

When it is determined that there is no input of the strong, medium, and weak switches SW1, SW2, and SW3 described above (S21), the microcomputer 2 inputs a high level signal to the input terminals P1, P2, and P3. The microcomputer 2 determines that there is no input of the strong, medium, and weak switches SW1, SW2, and SW3, and applies a low level signal to the output terminals P4, P5, and P6. This is because the low level signal through the resistors R4, R6, and R10 turns off the transistors Q1, Q2, and Q3 so that the power source AC is not applied to the blowing fan 30. 30) is driven off so that no wind is discharged at all (S22). At this time, the microcomputer 2 controls the wind direction variable stage A to return to its original state (S23), that is, the transistor Q4 is turned on by applying a high level to the output terminal P7 so that the relay RY1 is turned on. ), The wind direction tablet, the reverse motor 50 is reversely rotated to move the wind direction variable stage (A) at a predetermined angle. That is, when the wind direction tablet and the reverse motor 50 installed in the support 12 rotate in reverse rotation, the nut part 122 rotates simultaneously with the rotation of the bolt part 121 that rotates in conjunction with it, and thus the folding stand The variable blade 125 and the plurality of ribs 124 are moved in accordance with the movement of the 123.

As described above, the present invention provides a separate motor and a control means for controlling the motor in a vertical fan having a wind direction variable stage capable of discharging wind in all directions, and has an advantage of allowing the wind direction variable stage to be freely moved at a predetermined angle change. have.

The above description is only one embodiment of the present invention, and any change and modification can be made within the scope of the present invention.
