Next, the wind direction setting routine will be described with reference to FIG. 13. In step S17, the outputs of the first, second and third receivers 91, 99 and 105 are detected. Each of these receivers 9
When the outputs of 1, 99 and 105 are impossible outputs, for example, when the outputs of the second receiving unit 99 and the third receiving unit 105 are both larger than the output of the first receiving unit 91, that is, on the wall or the like. When the signal of the transmitter 84 is reflected and input, the input is invalidated so that the signal does not operate.

Then, in step S18, the direction of the transmitter 84 is calculated from the ratio of the outputs of the first, second and third receivers 91, 99 and 105. The calculation result may deviate from the actual direction of the transmitter 84 depending on the strength of the infrared signal. Therefore, the strength of the infrared signal is detected based on the outputs of the first, second, and third receivers 91, 99, 105 and the output from the AGC amplifier 97, and the detection result is corrected according to the strength of the infrared signal. Then, the direction of the transmitter 84 is calculated.

In step S19, the vertical swing motor 81
Is being driven, that is, whether or not vertical swing is being performed. If vertical swing is being performed, the process proceeds to step S20 and it is determined whether or not horizontal swing is being performed. If left / right swing is performed in step S20, the process proceeds to a swing center movement motor drive routine to be described later. If left / right swing is not performed, the swing center shift motor drive routine is executed and left / right swing is performed. The fan motor 69 is driven to vertically swing the fan head 69, and the fan head 69 is three-dimensionally swung by the horizontal swing and the vertical swing.

If the vertical swing is not performed in step S19, it is determined whether the horizontal swing is performed in step S21. If the horizontal swing is performed, the swing center moving motor drive routine is executed. At the same time, the vertical swinging motor is driven to perform horizontal swinging and vertical swinging with the center of swinging toward the transmitter 84. It should be noted that the direction of the transmitter 84 is driven by driving the motor 12 for moving the center of the swing so that the fan head 69 is moved.
Even when there is no range in which the beam can be directed to the transmitter 84, left and right swing is performed, so that the air can be blown in the direction of the transmitter 84, that is, in the direction of the user. Further, when the direction of the transmitter 84 drives the swing center moving motor 12 and the air cannot be blown in the direction of the transmitter 84 even in the state where left and right swing is performed, the sounding device is driven to notify the misuse. .

FIG. 1 shows a motor drive routine for moving the swing center.
Describing on the basis of 4, the swing center position of the fan head 69 with respect to the base 1 is detected based on the output of the swing center position detection sensor 16 in step S22, and in step S23, the transmitter 84 calculated in step S18 It is determined whether or not the direction and the current direction of the swing center position match. If the direction of the transmitter 84 does not match the swing center position in step S23, it is determined in step S24 whether or not the fan head 69 faces the right side of the direction of the transmitter 84 calculated in step S18. If it is, the motor 12 for swing center movement is driven in step S25 to drive the fan head 69.
Rotate the swing center of the to the left. The transmitter calculated in step S18 by repeating steps S22 to S25
The direction of 84 and the position of the center of swing of the fan head 78 are matched.

When it is determined in step S23 whether the swing center position of the fan head 69 and the transmitter 84 position match, the swing center position of the transmitter 84 calculated in step S18 is determined. Within a specified angle in the left-right direction centering on the
In this embodiment, when the transmitters 84 are within the range of about 2 °, it is determined that the transmitters 84 and the swing center position are coincident with each other. Since the air blown by the blower fan 76 is diffused, it can be blown in a relatively wide range centered on the direction of the fan head 69, and within a range of about 2 °, the fan 84 can be moved without moving the fan head 69. Can be blown in the direction of. Therefore, it is possible to reduce unnecessary driving of the swing center moving motor 12 and improve durability.

In step S24, it is determined whether or not the fan head 69 faces the right side of the direction of the transmitter 84 calculated in step S18. If it does not face the right side, that is, if it faces the left side, step S26. For swing center movement in
12 is driven to rotate the swing center of the fan head 69 to the right. Steps S22, S23, S24, and S26 are repeated, and the direction of the transmitter 84 calculated in step S18 and the position of the swing center of the fan head 69 are made to coincide with each other. During the adjustment of the direction of the fan head with respect to the center of the swing due to the movement of the swing center, the base 1
The wind direction adjustment display LED 29 provided on the switch panel 19 is blinked to indicate that the wind direction is being adjusted.

When the direction of the transmitter 84 and the swing center position of the fan head 69 coincide with each other in step S23, step S27
In step S, the motor 69 for swing center movement is stopped, and step S
In 28, it is determined whether or not the electric motor 74 is being driven. If the electric motor 74 is not being driven, the electric motor 74 is driven in step S29. Therefore, the fan head 69 can be rotated in the direction of the transmitter 84 and air blowing can be started only by controlling the wind direction adjustment switch 85 of the transmitter 84, and operability can be improved. Further, the electric motor 74 is driven after the fan head 69 faces the direction of the transmitter 84 to start blowing air, and it is an unnecessary place until the fan head 69 is directed toward the transmitter 84. There is no inconvenience such as blowing air to and scattering documents and the like.

Next, the air flow rate setting routine will be described with reference to FIG. 15. In step S30, it is determined whether "strong" operation is being performed, that is, whether the electric motor 74 is operating at high speed, and "strong" operation is performed. If you are driving, step S
At 31, a "light breeze" operation is performed, that is, the electric motor 74 is operated at an extremely low speed. If the "strong" operation is not performed in step S30, it is determined whether or not the "medium" operation is performed in step S32, that is, whether or not the electric motor 74 is in the medium speed operation, and the "medium" operation is performed. For example, "strong" operation is performed in step S33. If the "medium" operation is not being performed in step S45, it is determined in step S34 whether the "weak" operation is being performed, that is, whether or not the electric motor 74 is operating at a low speed. In step S35, "medium" operation is performed. If the "weak" operation is not performed in step S34, the "weak" operation is performed in step S36.

The timer setting routine will be described with reference to FIG. 16. In step S37, it is determined whether or not the 4-hour timer is set, and if it is set, the timer setting is canceled in step S38. Step S37
If the 4-hour timer is not set in step S39, it is determined whether or not the 2-hour timer is set in step S39. If it is set, the 4-hour timer is set in step S40. If the 2-hour timer is not set in step S39, step S39
In 41, it is determined whether or not the one-hour timer is set. If it is set, the two-hour timer is set in step S42. If the one-hour timer is not set in step S41, in step S43. Set a one hour timer.

Between each step of each routine,
When the receiving unit 31 receives the infrared signal of the transmitter 84, the routine being executed is executed, the process again shifts to the main routine, and the control based on the infrared signal received by the receiving unit 31 is performed.

As the above embodiment, the swing center moving motor 12 using the reversible motor and the left and right swing motor 80 using the one-way rotating motor are provided, but the left and right swing motor 80 is eliminated. Left and right swing may be performed using the swing center moving motor 12.
