If the infrared signal is received, step S2 is performed. It is determined whether or not the signal is a signal when the wind direction adjusting switch 62 is operated, and if the signal is the signal of the wind direction adjusting switch 62, the flow shifts to a wind direction changing routine described later.

If it is in the non-driving state, the process proceeds to step S1.

If the electric motor 47 is driven in step S3, the process proceeds to step S4, and it is determined whether or not the infrared signal from the transmitter 61 is the signal of the air volume adjustment switch 63. In step S4, if the signal from the transmitter 61 is the signal from the air volume adjustment switch 63, the routine proceeds to the air volume setting routine described later.

If the signal from the transmitter 61 is not the signal from the air volume adjusting switch 63 in step S4, step S5
Then, it is determined whether or not the signal is the signal from the left / right swing switch 65. If the signal is from the left / right swing switch 65, the routine goes to a later-described left / right swing routine.

If the signal from the transmitter 61 is not the signal from the left / right swing switch 64 in step S5, step S6
Then, it is determined whether or not the signal is the signal of the vertical swing switch 66. If the signal is the signal of the vertical swing switch 66, the routine shifts to a vertical swing routine which will be described later.

If the signal from the transmitter 61 is not the signal of the vertical swing switch 66 in step S6, step S7
Then, it is determined whether or not the signal is the signal from the wind direction left movement switch 67, and if the signal is from the wind direction left movement switch 67, the flow proceeds to the wind direction left movement routine described later.

If the signal from the transmitter 61 is not the signal from the wind direction left switch 67 in step S7, step S7.

If the signal from the transmitter 61 is not the signal from the downwind moving switch 70 in step S10, step S10.
At step 11, it is determined whether or not the signal is from the timer switch 64, and if the signal is from the timer switch 64, then the procedure goes to a timer setting routine described later.

If the signal from the transmitter 61 is not the signal from the timer switch 64 in step S11, step S12
Then, it is determined whether or not the signal is the signal of the power-off switch 71, and if it is the signal of the power-off switch 71, the process proceeds to step S13, the electric motor 47 is stopped to stop the operation, and the step S
At 14 the fan direction changing motor 14 is driven to direct the fan head 43 toward the front of the base 1 and the vertical swing motor.
Drive 53 to orient the fan head 43 substantially horizontally. Therefore,
Since the fan head 43 is facing the front of the base 1,
At the time of restarting, the user can surely determine the position of the swing center, and the usability can be improved. Also,
Since the fan head 43 faces substantially horizontally in front of the base 1, repacking can be easily performed.

Next, the wind direction setting routine will be described with reference to FIG. 12. In step S15, the first, second, third,
The outputs of the fourth light receiving units 34, 35, 36, 37 are detected. When the outputs of the respective receiving units 34, 35, 36, 37 are impossible outputs, for example, the output of the second light receiving unit 35 and the output of the third light receiving unit 36 are both larger than the output of the first light receiving unit 34. In this case, that is, when the signal of the transmitter 61 is reflected and input to a wall or the like, the input is invalidated and the input does not operate.

Then, in step S16, the direction of the transmitter 61 is calculated from the ratio of the outputs of the first, second, third, and fourth light receiving portions 34, 35, 36, and 37. The calculation result may deviate from the actual direction of the transmitter 61 depending on the intensity of infrared rays. Therefore, the first, second, third and fourth light receiving sections 34,
The intensity of the infrared signal is detected based on the outputs of 35, 36 and 37 and the output of the AGC amplifier 76, and the detection result is corrected according to the intensity of the infrared signal to calculate the direction of the transmitter 61.

In step S17, the vertical swing motor 53
Is driving, that is, whether or not vertical swinging is being performed. If vertical swinging is being performed, the wind direction changing motor drive routine is executed, and if vertical swinging is not being performed, A wind direction changing motor drive routine and a vertical swing motor drive routine are executed.

The wind direction changing motor driving routine will be described with reference to FIG. 13. In step S18, the direction of the fan head 43 with respect to the base 1 is detected based on the output of the left and right position detecting sensor 16, and in step S19, the wind direction changing routine. It is determined whether or not the direction of the transmitter 61 calculated in step S16 and the current direction of the fan head 43 match. If the direction of the transmitter 61 and the current direction of the fan head 43 do not match in step S19, it is determined in step S20 whether the fan head 43 faces right of the direction of the transmitter 61 calculated in step S16. If it is determined that it is facing right, the wind direction changing motor 14 is driven to rotate the fan head 43 leftward in step S21. Steps S18 to S21 are repeated to match the direction of the transmitter 61 calculated in step S16 with the direction of the fan head 43.

In step S20, it is judged whether or not the fan head 43 faces the right side of the direction of the transmitter 61 calculated in step S16. If it does not face right, that is, if it faces left, step S22. At, the wind direction changing motor 14 is driven to rotate the fan head 43 to the right. Steps S18, S19, S20 and S22 are repeated to match the direction of the transmitter 61 calculated in step S16 with the direction of the fan head 43. During the adjustment of the direction of the fan head 43, the wind direction adjustment display LED 31 provided on the switch panel 19 of the base 1 blinks to indicate that the wind direction is being adjusted.

When the direction of the transmitter 61 and the direction of the fan head 43 coincide with each other in step S19, the wind direction changing motor 14 is stopped in step S23, and in step S24, the up / down swing motor driving routine described later is completed. Determine whether or not. If the vertical swing motor drive routine is completed, it is determined in step S25 whether or not the electric motor 47 is being driven. If the electric motor 47 is not being driven, the electric motor 47 is driven in step S26. Therefore, the transmitter 61
Just by controlling the wind direction adjustment switch 62 of the fan head 43
The air can be rotated in the direction of the transmitter 61 and the air blowing can be started, and the operability can be improved. Also, the electric motor 47
Means that the fan head 43 is driven after the fan head 43 faces the direction of the transmitter 61 to start the air blow, and the fan head 47 is blown to an unnecessary place until the fan head 47 is directed to the transmitter 61. There is no inconvenience such as scattering documents.

If the vertical swing motor drive routine is not executed in step S24, that is, the transmitter 61
When the elevation position of the fan and the elevation angle of the fan head 43 are the same, the end signal of the vertical swing motor drive routine is input.

Next, the vertical swing motor drive routine will be described with reference to FIG. 14. In step S27, the elevation angle of the fan head 43 with respect to the base 1 is detected based on the output of the elevation angle detection sensor 58, and in step S28. At, it is determined whether or not the height position of the transmitter 61 calculated in step S16 of the wind direction changing routine and the elevation angle of the fan head 43 match.
